[0001] this application claims priority in accordance with the provisional application for U.S. patent No. 61/323856 entitled "Determination of radio link failure with enhanced interference coordination and cancellation", filed on April 13, 2010, the disclosure of which is totally incorporated herein by reference.

The technical field to which the invention relates.

[0002] Aspects of the present disclosure generally relate to wireless communication systems and more specifically to the determination of fault lines Radiocommunication systems using improved coordination and interference suppression.

The level of technology

[0003] wireless communication Networks are widely used to provide various communication services such as voice, video, packet data, messaging, broadcast, etc., These wireless networks may be multiple access networks capable of supporting multiple users by allocating available network resources. Examples of such multiple access networks include network multiple access code division multiple access (CDMA)network multiple access with time division multiplexing (TDMA), network multiple access frequency division multiple access (FDMA), network multiple access with ortogonal the m frequency division multiplexing (OFDMA) network and multiple access frequency division channels on the basis of single-carrier (SC-FDMA).

[0004] wireless communications Network may include multiple base stations that can communicate with multiple units of user equipment (UE). UE can communicate with the base station both in downlink and uplink communications. Downward communication line

(or straight line) refers to the communication line, passing from the base station to the UE, and the upward communication line (or reverse link) refers to the communication line, passing from the UE to the base station.

[0005] the base station may transmit data and control information on the downlink to the UE and/or may receive data and control information for uplink communications from the UE. For downlink transmission from the base station may experience interference caused by transmissions from neighboring base stations or other wireless radio frequency (RF) transmitters. On the uplink communication transmission from the UE may encounter interference caused by transmissions in uplink communication, which is performed with other UE communicating with neighboring base stations or other wireless radio frequency (RF) transmitters. This interference can reduce the effectiveness of both downlink and uplink communications.

[0006] in View of the fact that the demand for access to broadband CE and mobile communications continues to grow, increases the possibility of interference and congestion of the networks because of the larger number of UE that access the wireless network long range, and also because of the larger number of systems short-range wireless communications that are used in residential areas. Research and development continues to improve UMTS technologies not only to meet the growing demand for access to mobile broadband, but also to enhance and expand the experience by the user of mobile phone.

The invention

[0007] Existing criteria for analysis of fault conditions of the radio link can be unsatisfactory to reflect conditions among the hundreds that support the coordination of collective resources. In General, if the UE announces failure of the radio link, the UE ceases to communicate with the serving base station and performs a search for a new base station. If the UE is in the area with strong signals in which the interference is agreed between base stations through cell interfering providing some resources, the results of measurements UE to determine the fault lines of communication (RLF) can vary greatly depending on whether the measured resources given by us shall go through the cell, disruptive. If the UE measures the resources that were provided through the cell which causes interference, the UE may incorrectly declare a fault RLF (for example, because of the strong interference), although the UE can still access serving cell through the use of the resources provided through the cell which causes interference. Accordingly, the disclosed aspects to find the fault RLF based on the negotiation of collective resources with the use of provided resources.

The processor accepts a specialized message, provided that identifies the resource from the base station interfering. In another aspect, the processor receives the broadcast message and/or service message, provided that identifies the resource. The processor determines the signal quality of the provided resource, and if a certain signal quality reaches a predefined threshold, then there is a malfunction of the radio link.

The computer-readable medium contains program code, which when executed by one or more processors induces one or more processors to perform operations of detecting interference from the base station interfering in the network that supports the coordination and interference suppression, which includes the step of providing at least one resource of the wireless transmission, and a step of allocating at least one of the provided resource from the base station interfering on serving base station. The code also encourages one or more processors to receive special messages, provided that identifies the resource from the base station interfering. In another aspect, the program code causes the processor to receive broadcast messages and/or service message, provided that identifies the resource. The code also encourages one or more processors to determine the signal quality of the provided resource, and if a certain signal quality reaches a predefined threshold, then there is a malfunction of the radio link.

For clarity it should be noted that certain aspects of the technology are described below for LTE, and most of the following description uses terminology LTE.

[0023] the Technology described herein can be used in various wireless networks, such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA, and other networks. The terms "network" and "system" are often used interchangeably. A CDMA network may implement a radio technology such as technology universal terrestrial radio access (UTRA), CDMA2000® from the telecommunications industry Association (TIA), etc. Technology UTRA includes wideband CDMA (WCDMA) and CDMA other varieties. Technology CDMA2000® includes standards IS-2000, IS-95 and is-856 from the electronic industry Association (EIA) and TIA.

[0024] the TDMA Network may implement a radio technology such as global system for mobile communications (GSM). An OFDMA network may implement a radio technology such as expanded UTRA (E-UTRA), ultra-wideband mobile communications (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDMA and other Technologies UTRA and E-UTRA are part of the universal mobile communication system (UMTS).

For clarity it should be noted that certain aspects of the technology are described below for LTE or LTE-A (alternative collectively referred to as "LTE-A"), and in the most part, the following description uses terminology LTE-A.

[0025] Figure 1 depicts a network 100 for wireless communication, which may be an LTE-A. Wireless network 100 includes many of deployed Nodes (eNodeB) 110 and other network objects. eNodeB may be a station that communicates with the UE, and may also be called a base station, a node B, an access point, etc. Each eNodeB 110 may provide a zone of radio communication in a specific geographical area. In the 3GPP project, the term "cell" can refer to this particular geographic coverage area eNodeB and/or the eNodeB subsystem serving the coverage area, depending on the context in which the term is used.

[0026] the eNodeB may provide a zone of happy is ovasi for macrosty, picosat, femtocells and/or cells of another type. Typically, microsata covers a relatively large geographic area (for example, a radius of several kilometers) and can provide unlimited access by UE from the subscription service provider network access. Picosat covers a smaller geographic area and can provide unlimited access by UE from the subscription service provider network access. Femtocell covers a relatively small geographic area (for example, within the house) and, in addition to unlimited access, can also provide limited access by UE having communication with the femtocell (for example, UES in a closed subscriber group (CSG), UE users who are within the house, and so on). eNodeB for macrosty can be called macro eNodeB. eNodeB for picosat can be called Pico eNodeB. And eNodeB for femtocells may be referred to as Femto eNodeB, or a home eNodeB. In the example, which is depicted in figure 1, the eNodeB 110a, 110b and 110c are macro eNodeB for microsot 102a, 102b and 102, respectively. eNodeB h is a Pico eNodeB for picosat 102x. And eNodeB 110y and 110z are Femto eNodeB femtocell 102y and 102z, respectively. eNodeB is able to support one or more (e.g. two, three, four, etc.) cells.

[027] the Wireless network 100 may also include relay stations. Relay station is a station that receives a transmission of data and/or other information from the preceding station (for example, from the eNodeB, UE, and so on) and sends the data and/or other information to a subsequent station (for example, UE or eNodeB). Relay station may be a UE, which relays the transmission to the other UE. In the example, which is depicted in figure 1, the relay station 110r can communicate with the eNodeB 110a and UE 120r to facilitate the interaction between the eNodeB 110a and UE 120r. Relay station may also be called retransmission eNodeB, relay, etc.

[0028] the Wireless network 100 may be a heterogeneous (heterogeneous) network, which includes eNodeB different types, for example, the macro eNodeB, Pico eNodeB, Femto eNodeB, repeaters, etc. These eNodeB different types may have different transmit power levels, different coverage and different impact on interference in wireless network 100. For example, the macro eNodeB can have a high level of transmission power (for example, 20 W), while the Pico eNodeB, Femto eNodeB and the relay can have a lower power level (for example, 1 W).

[0029] the Wireless network 100 supports synchronous operation. For synchronous operation eNodeB can have the same frame sync, and transfer from different eNodeB can be when listello agreed time. For asynchronous operation eNodeB may have different frame synchronization, and transmission between different nodes eNodeB may be inconsistent over time. The technology described herein can be used for both synchronous and asynchronous work. In one aspect, the wireless network 100 can support duplex communication with the channel frequency division (FDD) or a duplex connection with a time division multiplexing (TDD). The technology described herein can be used for both FDD mode and TDD mode.

[0030] the Network controller 130 may connect with a number of eNodeB 110, and to provide coordination and management of these eNodeB 110. Network controller 130 may communicate with the eNodeB 110 via transit (reverse) connection. eNodeB 110 may also directly or indirectly interact with each other, for example, transit through the wireless connection or a wired backhaul.

[0031] the UE 120 are dispersed throughout the wireless network 100, and each UE may be stationary or mobile. The UE may also be called a terminal, mobile station, subscriber unit, a station, etc. UE may be a cellular telephone, personal digital assistants (PDA), wireless modem, a wireless communication port of the active device, a portable computer, a wireless telephone, the local station communication (WLL), etc. UE may have the ability to interact with the macro eNodeB, Pico eNodeB, Femto eNodeB, relay, etc. In figure 1 the solid line with double arrows indicates the desired transmission between the UE and the serving eNodeB, the eNodeB which is designed for serving the UE on the downlink and/or uplink communication. A dashed line with double arrows indicates the transmission between the UE and eNodeB interfering.

[0032] LTE uses orthogonal frequency division multiplexing (OFDM) on the downlink and frequency division multiplexing-based single-carrier (SC-FDM) for uplink communication. Technology OFDM and SC-FDM divides the system bandwidth into multiple (K) orthogonal subcarriers, which are also referred to as tones, bins, etc. Each subcarriers may be modulated with data. Typically, the modulation symbols sent in the frequency domain by means of OFDM and in the time domain by means of SC-FDM. The spacing between adjacent subcarriers may be fixed, and the total number (K) subcarriers may depend on the system bandwidth. For example, the interval of the subcarriers may be equal to 15 kHz, and the minimum allocation of resources (called "resource block") may be equal to 12 subcarriers (or 180 kHz). Followed the Sabbath.) nominal FFT size may be equal to 128, 256, 512, 1024 or 2048 for the corresponding system bandwidth equal to 1,25, 2,5, 5, 10 or 20 megahertz (MHz), respectively. The system bandwidth may be divided into sub-bands. For example, the subrange can cover a 1.08 MHz (i.e. 6 resource blocks), you may attend 1, 2, 4, 8 or 16 sub-bands for the corresponding system bandwidth equal to 1,25, 2,5, 5, 10 or 20 MHz, respectively.

[0033] Figure 2 depicts the frame structure for downlink FDD used in LTE. The time sequence of transmission for the downlink may be divided into blocks radiokatu. Each radiocat may have a predetermined duration (for example, 10 milliseconds (MS)), and can also be divided into 10 podkatov with indexes from 0 to 9. Each podcat may include two slots. Therefore, each radiocat may include 20 slots with indices from 0 to 19. Each slot may include L symbol periods, for example, 7 symbol periods for a normal cyclic prefix (as shown in figure 2) or 14 symbol periods for an extended cyclic prefix. 2L symbol periods in each potcake can be assigned indexes from 0 to 2L-1. Available time and frequency resources can be divided into resource blocks. Ka is every resource block may cover N subcarriers (for example, 12 subcarriers in one slot.

[0034] In the LTE eNodeB may send a primary synchronization signal (PSC or PSS) and secondary synchronization signal (SSC or SSS) for each cell in the eNodeB. For the FDD mode of the primary and secondary sync signals may be sent in symbol periods 6 and 5, respectively, in each of podkatov 0 and 5 of each radicata with normal cyclic prefix, as shown in figure 2. The signals can be used by the UE to detect and query cell. For FDD mode eNodeB may send a physical broadcast channel (SRF) in symbol periods 0 to 3 in slot 1 podagra 0. Channel SRF can transport specific system information.

[0035] the eNodeB may send a physical channel indicator format control (PCFICH) in the first symbol period of each podagra, as shown in figure 2. PCFICH may transfer the number (M) of symbol periods used for control channels, and the value of M can be 1, 2 or 3, and can also vary among podkatov. The value M may be equal to 4 for a small system bandwidth, for example, comprise less than 10 resource blocks. In the example shown in figure 2, the value of M equals 3. eNodeB may send the physical channel HARQ indicator (PHICH) and a physical control channel downlink (PDCCH) in the first M symbol p is ridah each podagra. In the example shown in figure 2, the channels PDCCH and PHICH are also included in the first three character of the period. PHICH can convey information to support hybrid automatic retransmission (HARQ). PDCCH can convey information about resource allocation uplink communication and downlink for the UE, and information about the power control channel uplink communication. eNodeB may send the physical shared channel downlink (PDSCH) in the remaining symbol periods of each podagra. PDSCH can transport data for the UE, which is scheduled for data transmission on the downlink.

[0036] the eNodeB may send the PSC, SSC and SRF in the middle of 1.08 MHz of the system bandwidth used by eNodeB. eNodeB may send PCFICH and PHICH across the system bandwidth in each symbol period in which leave these channels. eNodeB may send the PDCCH to the UE groups in certain parts of the system bandwidth. eNodeB may send PDSCH to the UE groups in certain parts of the system bandwidth. eNodeB may send the PSC and SSC, the strategic missile forces, PCFICH and PHICH using broadcast to all UE may send the PDCCH using unicast to a specific UE and may send PDSCH, using unicast to a specific UE.

[0037] a Lot of nursnig items can be available in each symbol period. Each resource element may cover one of subcarriers in one symbol period, and can also be used to send one modulation symbol, which may be real or complex value. For symbols used for control channels, the resource elements that are not used for reference signal in each symbol period, can be collected into groups of resource elements (REG). Each REG may include four resource element in one symbol period. PCFICH may take four REG, which can be located at approximately the same frequency in symbol period 0. PHICH may take three groups REG that can be dispersed on a frequency of one or more configurable character periods. For example, all three REG for PHICH may belong to a character period 0, or can be scattered symbol periods 0, 1 and 2. PDCCH may take 9, 18, 36 or 72 REG that can be selected from the available REG in the first M symbol periods. For PDCCH may be available only for specific combinations of REG.

[0038] the UE may be known specific REG used for PHICH and PCFICH. UE can search for various combinations REG for PDCCH. Typically, the number of combinations to search is less than the number of available combinations for all UE in PDCCH. eNodeB which may send the PDCCH to the UE in any of the combinations, who will find the UE.

[0039] the UE may be located in the service area of a few eNodeB. One of these eNodeB may be selected to service the UE. Serving eNodeB may be selected based on various criteria such as received power, the losses in the transmission path, the signal-to-noise ratio (SNR), etc.

[0040] Figure 3 depicts a block diagram that conceptually depicts an exemplary structure podagra FDD and TDD (only non-podagra) in uplink communication technology long term evolution (LTE). The available resource blocks (RB) for uplink communication can be divided into a data section and a control section. The control section may be formed on the two boundaries of the system bandwidth and may have a configurable size. Resource blocks that are in the management section, can be allocated to the UE for transmission of control information. The data section may include all of the resource blocks that are not part of the management section. The structure, which is shown in figure 3, leads to the fact that the data section includes adjacent subcarriers, and this structure can provide the opportunity to highlight one UE all adjacent subcarriers in the data section.

[0041] For a UE may be assigned resource blocks in the control section, for transmitting control information on the eNodeB. The UE can also be assigned resource blocks in the data section, data on the eNodeB. The UE may send control information on a physical control channel uplink communication (PUCCH) through the allocated resource blocks in the control section. The UE may transmit a physical shared channel uplink communication (PUSCH) through the allocated resource blocks in the partition data, or data only or data and control information. Transmission via uplink communication may include two slots podagra, and can also jump in frequency, as shown in figure 3. In accordance with one aspect, when a soft work with one carrier parallel channels can be transmitted through the UL resources. For example, the control channel and data parallel control channels and parallel data channels can be transmitted by the UE.

[0042] Figure 4 depicts a block diagram of a design of a base station/eNodeB 110 and UE 120, which may be one of the base station/eNodeB and one of the UE shown in figure 1. According to the scenario of limited communication base station 110 may be a macro eNodeB 110c, which is depicted in figure 1, and UE 120 may be a UE 120y. Base station 110 may also be a base station of a different type. Base station 110 may be equipped with antennas 434a-434t, a UE 120 may be equipped with antennas 452a-452r.

[0043] the base station 110 plumage is surrounding the processor 420 may receive data from the source data 412, and to accept control information from controller/processor 440. The control information may be intended for the strategic missile forces, PCFICH, PHICH, PDCCH, etc. Data can be used for PDSCH, etc. the Processor 420 may be processed (for example, to encode and create the character table) data and control information to obtain data symbols and control symbols, respectively. The processor 420 may also generate reference symbols, for example, PSS, SSS, and the reference signal for a specific cell. Transmit (TX) processor 430 with multi-input and multi-output (MIMO), as required, may perform spatial processing (for example, pre-coding) of data characters, control characters and/or the reference symbols, and may also provide output character streams the modulators 432a-432t (MOD). Each modulator 432 can handle corresponding output character stream (for example, for OFDM, etc.) to obtain output samples. Each modulator 432 may be further processed (for example, to convert to analog form, amplification, filtering, and transformation with increasing frequency) the output stream of samples to obtain a signal downlink. Signals downlink from modulators 432a-432t can be transmitted via the antenna 434 is-434t, respectively.

[0044] AT UE 120 antenna a-452 g can receive signals downlink from the base station 110, and may provide received signals to demodulators 454a-454r (DEMOD), respectively. Each demodulator 454 is capable of handling (for example, to perform filtering, amplification, conversion with decreasing frequency and quantizing) the corresponding received signal to obtain input samples. Each demodulator 454 able to further process the input samples (for example, for OFDM, etc.) to obtain received symbols. The detector 456 MIMO capable of receiving the received symbols from all demodulators 454a-454r, as necessary to perform MIMO detection on the basis of the received symbols and provide detected symbols. The receive processor 458 able to handle (for example, to perform demodulation, reverse rotation and decode) the detected symbols, provide decoded data for UE 120 to a receiver 460 data, and provide decoded control information to a controller/processor 480.

[0045] On the uplink communication UE 120 transmit processor 464 able to accept and process data (for example, PUSCH) from the source 462 data and control information (for example, PUCCH) from controller/processor 480. The processor 464 is also able to generate about the priori symbols for the reference signal. As necessary, the symbols from transmit processor 464 may be pre-encoded by the transmitting (TX) processor 466 MIMO, further processed by modulators 454a-454r (for example, for SC-FDM, etc) and transmitted to the base station 110. At base station 110, the uplink signals from UE 120 may be received by antennas 434, processed by demodulators 432, as necessary, detected by detector 436 MIMO, and further processed by the receiving processor 438 to obtain decoded data and control information sent by UE 120. The processor 438 may provide the decoded data to the receiver 439 data, and the decoded control information to controller/processor 440. Base station 110 may send messages to other base stations, for example, the X2 interface 441.

[0046] the Controller/processor 440 and 480 may direct the operation at base station 110 and UE 120, respectively. The processor 440 and/or other processors and modules at base station 110 may perform or direct the execution of various processes on the technology described in this document. The processor 480 and/or other processors and modules UE 120 may also perform or direct the execution of the functional blocks, which illustria the Ana 7, and/or other processes for the techniques described herein. The storage device 442 and 482 may store data and program codes for base station 110 and UE 120, respectively. The scheduler 444 able to schedule the UE for data transmission on the downlink and/or uplink connection.

[0047] Figure 5 depicts a block diagram that illustrates the division of TDM in a heterogeneous network, in accordance with one aspect of the disclosure. The first row of blocks illustrates the allocation of podkatov for Femto eNodeB and the second row of blocks illustrates the allocation of podkatov for macro eNodeB. Each eNodeB is protected static podcat, during which another eNodeB has a static forbidden podcat. For example, Femto eNodeB has protected podcat (podcat U) in potcake About corresponding the forbidden podagra (podagra N) in potcake 0. Similarly, the macro eNodeB has protected podcat (podcat U) in potcake 7 corresponding to the forbidden podagra (podagra N) in potcake 7. Podckaji 1-6 dynamically allocated as a protected podagra (AU), forbidden podagra and General podagra (AC). In the process of dynamically allocating shared podkatov (AU) in podkraj 5 and 6, the Femto eNodeB, macro eNodeB may transmit data.

[0048] Protected podckaji (such as podckaji U/AU) have reduced the room is and the high quality of the channel in the that acting eNodeB does not intend to transfer unicast schedule. In other words affecting eNodeB does not prohibit the transfer, but rather intend to reduce interference in the protected pocketrak by refraining from scheduling unicast schedule. Forbidden podckaji (such as podckaji N/AN) have no data to provide nodes eNodeB, the affected, the ability to transfer data with low noise level. General podckaji (such as podckaji C/AC) have the quality of the channel, depending on the number of neighboring eNodeB, which transmit the data. For example, if the neighboring eNodeB transmit data through common podkatov, the quality of the shared channel podkatov may be lower quality protected podkatov. The quality of the shared channel podkatov may also be lower in the extended limited area (EBA) UE, which is strongly affected by influencing eNodeB. UE of the EBA may belong to the first eNodeB and reside in the service area of a second eNodeB. For example, a UE communicating with a macro eNodeB, which is near the border of the limit range of the service area Femto eNodeB, UE is EBA.

[0049] Another exemplary control scheme for interference, which can be used in LTE/-A, is a slow adaptive management interference. When used in the research Institute of the method for managing interference, resources are agreed and allocated within the required time, which far exceeds the duration of the intervals of the planning. The aim of the scheme is to search for combinations of transmission capacity for transmitting all eNodeB and UE for all time or frequency resources to the maximum extent increases the overall utility of the network. "Usefulness" can be defined as a function of the user data transmission rate, delay flow quality of service (QoS) and fairness metric. This algorithm can be computed via the main object that has access to all information used to solve optimization and controls all camera objects, such as, for example, network controller 130 (Fig 1). This is the main object may not always be practical or even desirable. Based on the above, in alternative aspects can be used a distributed algorithm that makes decisions about the use of the resource based on the information about the channel from a specific group of nodes. Therefore, the algorithm is slow adaptation of interference can be deployed using either the main subject or by allocation algorithm for different groups of nodes/objects in the network.

[0050] the UE can work with the dominant interference, in which the om UE may observe strong interference from one or more eNodeB, disruptive. The scenario with the dominant interference may occur due to limited communication. For example, in figure 1 UE 120y may be close to the Femto eNodeB 110y, and may have high received power for eNodeB 110y. However, the UE 120y may not be able to access the Femto eNodeB 110y due to limited communication, and may instead connect to the macro eNodeB 110c with lower received power (as shown in figure 1) or Femto eNodeB 110z, also with lower received power (not illustrated in figure 1). Then UE 120y may observe strong interference from a Femto eNodeB 110y on the downlink, and may also cause high interference to eNodeB 110y on the ascending line. When working in connected mode in this scenario, the dominant interference, the UE 120y may experience interference that are sufficient to UE 120y could no longer maintain an acceptable connection with the eNodeB 110 C.

[0051] In addition to the waiver of the signal power observed at the UE in such a scenario, with the dominant interference, the UE can also observe the delay synchronization signal downlink even in synchronous systems, due to different distances between the UE and many eNodeB. eNodeB in a synchronous system, presumably synchronized across the system. However, for example, if we consider the UE, which is located at a distance of 5 km from the macro eNode, the propagation delay of any signal downlink, received from the macro eNodeB will last approximately 16,67 ISS (5 km/3×10⁸then there is the speed of light, "c"). When comparing this signal downlink from the macro eNodeB signal on the downlink from much closer Femto eNodeB, the difference synchronization can approach the level of the error time to live (TTL).

[0052] in Addition, the difference synchronization can affect the suppression of interference in the UE. The suppression often uses the properties of the cross-correlation between the combination of multiple versions of the same signal. By combining multiple copies of the same signal interference can be easier identified, because if the interference will be present in each copy of the signal, then he most likely will not be in the same location. When using cross-correlation composite signals to define and distinguish the portion of the actual signal from the noise, allowing the opportunity suppression.

[0053] the Script with the dominant interference may also occur due to range expansion. Expansion of the range occurs when the UE connects to the eNodeB with fewer losses in the transmission path and a lower signal-to-noise ratio (SNR) among all the eNodeB, the detected group is a rotary UE. For example, in figure 1 UE 120x may detect macro eNodeB 110b and Pico eNodeB 110x. In addition, the UE may have lower received power for eNodeB 110x than eNodeB 110b. UE 120x may connect with Pico eNodeB 110x in case of loss in the transmission path for eNodeB 110x less than the losses in the transmission path to the macro eNodeB 110b. This may cause less interference to the wireless network at a given data rate for UE 120x.

[0054] In a wireless network with the permitted expansion of the range of improved coordination mistovich interference (eICIC) may provide the UE can receive service from the base station with less power (for example, Pico base station, Femto base station, repeater and so on) in the presence of the macro base station with the highest signal strength downlink, and may provide the UE with the possibility of obtaining service from the macro base station when the signal is present, creating a strong interference from the base station with which the UE to connect prohibited. As discussed above, eICIC can be used for alignment of resources so that the base station interfering, could free up some resources, but also allowed you to manage and transfer data between the UE and the serving base station. If your network supports eICIC, the base station negotiate and coordinate the use the of resources to reduce and/or eliminate interference from the cell, disruptive, releasing a part of its resources. Accordingly, the UE can access the serving cell even with strong signals through the use of the resources provided through the cell which causes interference.

[0055] For the UE which supports eICIC, the existing criteria for the analysis of fault conditions of the radio link may not satisfactorily reflect the consistent cells. In General, if the UE announces failure of the radio link, the UE ceases to communicate with the base station and performs a search for a new base station. If the UE is in the area with strong signals in which the interference is agreed between base stations through cell interfering providing some resources, the results of the measurement performed by the UE to measure the signal-to-noise ratio (SNR) or the error rate of the decoding channel PDCCH, may vary greatly depending on whether the measured resources provided through the cell which causes interference. If the UE measures the ratio of the SNR or the error rate of the channel decoding PDCCH for resources that are not provided through the cell which causes interference, the UE may incorrectly declare a fault RLF due to strong interference, despite the fact that the UE can still refer to servicing the th cell through the use of resources, provided by cell interfering.

[0056] 6 depicts a block diagram that conceptually illustrates macrosoma 601 within the wireless network 630, configured in accordance with one aspect of the present disclosure. Wireless network 630 is a heterogeneous network, in which macrosoma 601 served by the macro base station 600. Two additional cell, femtocell 603 served through Femto base station 602, and picosat 606 served by the Pico base station 605, are covered by the service area macrosty 601. Although figure 6 shows only macrosoma 601, the wireless network 630 may include many macroshot, such macrocode 601.

[0057] the UE 604 is located within macrosty 601, and within femtocells 603. Communication with the Femto base station 602, which is located in the femtocell 603 is available only for the allowed UE. In this example, the UE 604 are not allowed to communicate through the Femto base station 602. Accordingly, the UE 604 communicates with the macro base station 600. When entering UE 604 in the femtocell 603, interference caused by the Femto base station 602 via signal 608, disruptive impact on the quality of the signal 609 in the communication channel between the UE 604 and the macro base station 600. As you increase the Oia noise, UE 604, which supports eICIC, identifies resources that provides a Femto base station 602, based on the approval of interference from the macro base station 600. Resources can be defined in the time domain, frequency domain, or even in combination of resources frequency and time domains. If the resources are based on the time domain, the base station 602, disruptive, does not use some of their own available podkatov in the time domain, as discussed above with reference to figure 5. If the resources are based on the frequency domain, the base station 602, disruptive, does not use some of their own available subcarriers in the frequency domain. If the resources are based on a combination of frequency and time fields, the base station 602, disruptive, does not use the resources defined by frequency and time domains.

[0058] After the identification of resources UE 604 receives the signal quality of the provided resources. For example, the signal quality can be obtained by using the error rate for PDCCH (physical control channel downlink) provided resources. Information about the quality of the signal can be received by UE 604 by RA the personal analysis of the error rate, includes decoding channel PDCCH and the calculation of the error rate on the basis of the decoded signal, or by projecting the error rate of the analyzed signal-to-noise ratio (SNR) of the channel PDDCH. In one aspect, the measurement result is information about the state of the channel (CSI), which among other things may include the measurement result of one or more indicators of channel quality (CQI), indicators matrix pre-coding (PMI) or indicators rank (RI). If the error rate of the channel PDCCH in provided resources exceeds the predefined level of error rate, the UE 604 announces failure of the radio link signal and ends the connection with the macro base station 600. In one example declares a fault of a radio link if the frequency of occurrence of errors reflects an unacceptably high value, which does not allow the exposed resources accordingly to maintain the signal in the communication channel. If the error rate of resources does not exceed a predetermined level (for example, a level, which allows to provide resources accordingly to maintain the signal in the communication channel), the UE 604 may continue to access the macro base article is ncii 600 through resources provided Femto base station 602.

[0059] In another example, before receiving the error rate of the channel PDCCH resources, the UE 604 may identify and suppress interference from common control signals transmitted by a Femto base station 602 via the provided resources. Even if the Femto base station 602 provides resources in accordance with the protocols management agreement eICIC, the Femto base station 602 may only be clear and provide data slots provided podkatov. As for example in E-UTRAN, the Femto base station 602 supports the control slots for transmitting the common control signal, a common reference signal (CRS), channels PDCCH/PCFICH to support signal transmission, message with system information blocks (SIB), system message retrieval call, etc. In one example, before determining the quality of the signal and receiving the level of error rate, UE 604 identifies these common control signals and suppresses interference that relate to those signals.

[0060] In another example, before receiving the error rate of the channel PDCCH resources, the UE 604 identifies what resources were provided. To identify resources can be implemented in many ways. In one example, the UE 604 receives the configuration signal from the service of ivalsa base station, that is, from the macro base station 600 that identifies the resources. The configuration signal may be system messages of any type, such as specialized signals (for example, the message management radio resource (RRC)), broadcast messages (for example, service messages, such as messages system information blocks (SIB)), etc. Configuration signal, which is received from the serving base station may include information such as the range of physical identification of a base station or a power class of a base station, each of which UE 604 may be used to determine the considered base station, the resources which are available to obtain the error rate channel PDCCH.

[0061] In alternative examples, the UE 604 may receive service message, which is transmitted by the base station (for example, the Femto base station 602)interfering with, instead of receiving a message from the macro base station 600, identifying resources. When the Femto base station 602 provides specific resources in accordance with the agreement Protocol eICIC, she sends or transmits the service message to any of your own clients, identifying specific provided the e resources. In one example, the UE 604 intercepts such service signals and reads the information about available resources.

[0062] In other examples, the resources are configured according to the pattern of limited use for the Femto base station 602. In such alternative aspects of the negotiation Protocol eICIC instructs the Femto base station 602 periodic limit any use of specific resources. During this period of restriction Femto base station 602 cleanses and provides data slots provided podkatov, and also cleans and provides all other resources provided podkatov, including the reference signals. That is, the Femto base station 602 does not transmit the common control signals provided by resources. Can be defined different duration periods to Femto base station 602 did not use the resources for a certain period of time. In one example, the designated duration is measured in milliseconds (MS) (for example, every 8 MS, 10 MS, 40 MS, and so on). In such aspects, the UE 604 receives the frequency error channel PDCCH during periods of limited use, in addition UE 604 is not listening on any common control signals for additional inhibition is of interference. In one aspect of the periodic resources are polkadraai MBSFN (multimedia broadcast single frequency network), and therefore, the UE 604 does not extinguish common control signals.

[0063] the UE 607 is located within macrosty 601, as well as within picosat 606. In accordance with a feature to extend the range of your wireless network 630 LTE-A, the load on the cell is balanced by connecting UE 607 with Pico base station 605 for communication. However, the power level for signal 611 in the communication channel between the UE and the Pico base station 605 below the power level of the signal 610 that generates noise, which is transmitted from the macro base station 600. Interference caused by signal 610, disruptive, encourage UE 607 to the beginning of the analysis for failure radio link. UE 607 identifies the resources from the base station interfering, that is, from the macro base station 600. In one example, UE 607 can identify resources based on the message installation/separation, which is transmitted from the serving cell (for example, from the Pico base station 605). The message can also include a range of physical identification of the base station power class of a base station or other information about treated and provided resources base station interfering. As illustrated, picosat 06 overlaps macrosoma 601. Accordingly, the Pico base station 605 contains information that identifies the resources provided by the macro base station 600 to implement the functions of the expansion range. It is advisable that the Pico base station 605 passed on such information. In particular, in one aspect of the Pico base station is the dominant transmitter and may be easier to provide this information to the UE. After, UE 607 identifies these resources, UE 607 may receive the signal quality of the provided resources, for example, by obtaining the error rate of the channel PDCCH those resources. On the basis of the level of error rate UE 607 determines to declare whether the fault lines of communication (RLF).

[0064] In one example of a specific resource group time domain (for example, podckaji) and/or resource blocks (RB) frequency domain are assigned as resources. Resources can include a group of podkatov and/or frequency resource blocks that do not contain region of the channel PDCCH. To determine the failure radio link measured by this particular set of resources (for example, podckaji).

[0065] In another aspect of defining a new control channel, which was originally part of the data channel. The UE uses this new control channel R-PDCH to obtain the error rate to determine the fault line radio. For example, in a wireless network 630, which is illustrated in Fig.6, when the UE 604 detects interference from a signal 608, disruptive, which are sufficient to begin the analysis of the failure of the radio link, the UE 604 receives the identification information about the resources, which identifies the group of podkatov and/or frequency resource blocks (RB). In the example, when a group of podkatov and/or frequency resource blocks not contains the channel PDCCH, the UE 604 does not perform calculation of the error rate for the channel PDCCH. Instead, the UE 604 receives the signal quality of the provided resources in other ways (for example, through the use of channel R-PDCCH to obtain the error rate). If the group podkatov assigned in the quality of resources is determined in the time and frequency domains, the group is a subset of podkatov MBSFN cell which causes interference, the positions of the resource blocks configured to prevent conflict with the control channels/frequency domain data serving cell (i.e. the macro base station 600).

[0066] 7 illustrates a method 700 of determining the fault lines of communication (RLF) with improved coordination and interference. At step 702 UE detects interference from the base station interfering in the network that supports improved according to the Finance and suppression (eICIC). At step 704 UE receives a message that identifies the provided resource of the base station interfering. At step 706 UE determines the signal quality of the provided resource. At step 708 UE determines whether the signal quality is a pre-defined threshold value. Based on this determination, the management process may proceed to step 710 where the UE announces fault line communication (RLF). Alternatively, at step 712 UE may communicate with a serving cell.

[0067] In one configuration, the UE 120 is configured for wireless communication includes means of detecting interference. In one aspect, the detection device may be an antenna 452a-452r, demodulators 454a-454r, the receiving processor 458, controller/processor 480 and/or memory 482 configured with functions that are transferred by the picker. UE 120 is also configured with the ability to include a means of receiving messages. In one aspect, the tool may be an antenna 452a-452r, demodulators 454a-454r, the receiving processor 458, controller/processor 480 and/or memory 482 configured with functions that are transferred by means of transfer. UE 120 is also configured with the ability to include means which determine signal quality. In one aspect, the means for determining may be the controller/processor 480 and/or memory 482 configured with functions that are transferred by means of measurement. UE 120 is also configured with the ability to include a means of declaring a malfunction of the radio link. In one aspect, the means ads can be a storage device 482 and the controller/processor 480, configured to perform the functions transferred by means of ads. In another aspect, the aforementioned means may be a module or any device configured to perform the functions listed above tool.
