[0031] in Addition, describes the different ways of implementation in relation to the mobile device. The mobile device may also be called a system, subscriber unit, subscriber station, mobile station, mobile devices, remote station, remote terminal, access terminal, user terminal, terminal, wireless communication device, user agent, user device, or user equipment (UE). The mobile device may be a cellular phone, phone, phone according to the Protocol Session Initiation (SIP), the local station communication (WLL), a personal digital assistant (PDA), a handheld device having wireless connection, the computing device or another processing device associated with a wireless modem. In addition, different ways of implementation are described here with respect to the base station. The base station can be used for communication with the mobile device(s) and may also be called an access point, a Node b or some other term.

[0032] in Addition to the CSO, various aspects or characteristics described herein may be implemented as a method, device, or product of manufacture using standard programming and/or engineering techniques. Used in the present description, the term "product manufacturing" is intended to encompass a computer program accessible from any machine-readable device, carrier or media. For example, machine-readable media may include, but are not limited to, magnetic storage devices (e.g. hard disk, floppy disk, magnetic tape, and so on), optical disks (such as compact disc (CD), digital versatile disk (DVD), and so on), smart cards and devices with flash memory (e.g., EPROM, card, stick, key drive etc).

The term "machine-readable medium" may include, but are not limited to, wireless channels and various other media capable of storing, contain and/or transfer command(s) and/or data.

[0033] Below with reference to FIG.1 illustrates a wireless communications system 100, in accordance with various aspects presented in this op is sanija. System 100 may contain one or more dots 102 access that receive, transmit, repeat, and so on, the wireless signals to each other and/or one or more terminals 104. Each base station 102 may contain multiple circuits of the transmitter and receiver circuit, for example, one for each transmit and receive antennas, each of which can, in turn, contain many components associated with transmission and reception of a signal (e.g., processors, modulators, multiplexers, demodulators, demultiplexes, antennas and so on). The terminal 104 may be, for example, cellular phones, smartphones, laptops, handheld communication devices, handheld computing devices, satellite radios, global positioning, assistant PDA and/or any other suitable device for communicating over the wireless communication system 100. In addition, each terminal 104 may include one or more circuits (schemes) of the transmitter circuits (schemes) of the receiver, such as are used for systems with many inputs and many outputs (MIMO). Each transmitter circuit and the receiver circuit may contain many components associated with transmission and reception of a signal (e.g., processors, modulators, multiplexers, demodulators, demultiplexes, antennas and so on), how would the ü clear to experts in the given field of technology.

[0034] As illustrated in FIG.1, each access point provides coverage due to a particular geographical region 106. The term "cell" can refer to an access point and/or its coverage area depending on the context. To improve system capacity, the coverage area of the access point can be divided into multiple smaller areas (e.g., three smaller areas 108A, 108B and 108C). Each smaller area is served by a respective base transceiver subsystem (BTS). The term "sector" can refer to a BTS and/or its coverage area depending on the context. For divided into sectors of a cell of the base transceiver subsystem for all sectors of the cell is typically combined within the access point for the cell.

[0035] the Terminal 104 is typically distributed throughout the system 100. Each terminal 104 may be stationary or mobile. Each terminal 104 may communicate with one or more points 102 to access the forward and reverse links at any given time.

[0036] For a centralized architecture, a system controller 110 is connected to the access points 102 and provides coordination and control points 102 access. For a distributed architecture point 102 access can communicate with each other somehow. Communication between access points using the system controller 110 sludge is similar might be called reverse alarm.

[0037] the Techniques described in the present description, can be used for system 100 with sektoritasandi cells, as well as for a system with resectorization cells. For clarity, a further description is given for a system with sektoritasandi cells. The term "access point" is used in a fixed station that serves a sector as well as for fixed station that serves a cell. The terms "terminal" and "user" are used interchangeably, and the terms "sector" and "access point" are also used interchangeably. Serving access point/sector is the access point/sector with which the terminal is transmitting traffic on the reverse link. The neighboring access point/sector is the access point/sector with which the terminal is no transmission of traffic on the reverse link. For example, an access point that serves only direct line of communication to the terminal should be considered neighboring sector for interference management purposes.

[0038] Below with reference to FIG.2 illustrates a system 200 is a wireless connection in accordance with the variations in the implementation presented in this description. The system 200 includes a base station 202, which may include multiple groups of antennas. For example, one group of antennas may include antennas 204 and 206, etc the guy group may contain antennas 208 and 210, and an additional group may include antennas 212 and 214. Illustrates two antennas for each group of antennas; however, for each group can be used more or fewer antennas. Base station 202 can further include a circuit (scheme) of the transmitter and the circuit (scheme) of the receiver, each of which can, in turn, contain many components associated with transmission and reception of a signal (e.g., processors, modulators, multiplexers, demodulators, demultiplexes, antennas and so on), as should be clear to a person skilled in the technical field.

[0039] the base station 202 can communicate (exchange information) with one or more mobile devices, such as mobile device 216 and the mobile device 222; however, it should be clear that the base station 202 can communicate, essentially, with any number of mobile devices similar to mobile devices 216 and 222. Mobile devices 216 and 222 can be, for example, cellular phones, smartphones, laptops, handheld communication devices, handheld computing devices, satellite radios, global positioning, assistant PDA and/or any other suitable device for communication system 200 wireless. As shown, the mobile device is about 216 is in communication with antennas 212 and 214, where the antenna 212 and 214 transmit information to the mobile device 216 in a straight line 218 and receive information from mobile device 216 through a return line 220. In addition, the mobile device 222 is in communication with antennas 204 and 206, where the antenna 204 and 206 transmit the information to the mobile device 222 in a straight line 224 and receive information from mobile device 222 through a return line 226. In the system duplex transmission with frequency division multiplexing (FDD) direct link 218 may use different frequency range than the one that uses reverse communication line 220, and a direct communication line 224 may use different frequency range than the one that uses reverse communication line 226, for example. Additionally, the duplex communication system with time division multiplexing (TDD) is a direct communication line 218 and a return line 220 can use a common frequency band, and a direct communication line 224 and a return line 226 can use a common frequency range.

[0040] the Set of antennas and/or the area in which they are assigned for communication, can be called a sector of the base station 202. For example, multiple antennas can be assigned for communication with the mobile device in a sector of the areas covered by base station 202. When communicating over a direct communication lines 218 and 224 transmitting antennas of the base station and 202 can use the formation of the pattern to improve the signal-to-noise direct communication lines 218 and 224 for mobile devices 216 and 222. In addition, while the base station 202 uses the formation of a pattern for transfer to mobile devices 216 and 222 located randomly within the associated coverage area, mobile devices in neighboring cells can be subject to less interference as compared with transmission of the base station through a single antenna to all its mobile devices.

[0041] According to the example, the system 200 may be a communication system with many inputs and many outputs (MIMO). Additionally, the system 200 may use essentially any type of technique duplex operation to separate communication channels (for example, a direct communication line, a return line...), such as FDD, TDD, etc., in Addition, the system 200 may use the broadcast information to implement dynamic power control for the reverse link. In accordance with the illustration, base station 202 can transmit information related to power control in direct communication lines 218 and 224 mobile devices 216 and 222. Information related to power control may be included in the assignment data channel of the reverse link, secured mobile devices 216 and 222. The base station 202 may broadcast the indication of interference from the other sector. For example, base station 202 may broadcast the importance of the regular interference of the other CE the Torah every supercar and values fast other sector interference for each subband in each frame of the reverse link. Interference from the other sector vemayca on a mobile device (not shown) in other sectors not served by base station 202. Additionally, mobile devices 216 and 222 receive transmitted by broadcasting the values of other sector interference from base stations other than the base station 202. Mobile devices 216 and 222 may also receive information relating to power management included in the assignment from the base station 202. Accordingly, the mobile device 216 and 222 may use the accepted values of other sector interference information and power control to adjust the power on the data channels of the reverse link. For example, mobile devices 216 and 222 may use values fast other sector interference of the support and adjustment of the values of Delta transfer used to adjust the spectral power density of the data channels of the reverse link. In addition, mobile devices 216 and 222 may use the value of regular interference from the other sector to support and adjust the slow Delta values, which may be associated with base station 202 using the reverse communication lines 220 and 226, respectively. Slow Delta values can be used by base station 202 as suggested values for future assignments.

[0042] Below with the link the mi in FIG.3 illustrates a system 300 wireless which implements the transmission power control on the reverse link based on the reviews produced values of interference, among others. The system 300 includes a base station 302 that communicates with the mobile device 304 (and/or any number of disparate mobile devices (not shown)). Base station 302 can transmit information related to power control, the mobile device 304 through the channel of direct lines of communication and broadcast values other sector interference to mobile devices located in other areas not serviced by base station 302. Additionally, the base station 302 can receive information from mobile device 304 through the channel of the reverse link. In addition, the system 300 can be a MIMO system.

[0043] the base station 302 can include block 306 plan, block 308 broadcast other sector interference (OSI) and the block 310 broadcast offset interference. Block 306 plan, among other things, provides a channel assignment to the mobile device 304. The assignment may include the ID of the channel that defines the set of ports of the transition in the tree channel. The appointment may also determine the format of the package. The packet format may be encoded and/or modulated, which should be used for transmission on the assigned resources. In addition, the appointment may includes the ü the parameters which indicate that the appointment is the appointment of an extended duration of transmission and/or whether to replace or Supplement an existing destination. In accordance with an aspect of the present disclosure, each package format has an associated minimum value of the ratio of carrier to interference (C/I) for the data channel (hereinafter referred to as DataCtoImin). Is DataCtoIminmeets the minimum C/I required to achieve a certain coefficient (frequency) errors in a particular try a hybrid query automatically repeat (HARQ). In addition, the block 306 plan passes the minimum and maximum values exceeding the carrier signal over thermal noise for the data channel (hereinafter referred to as DataCoTminand DataCoTmax). These values can be included in the appointment issued by the block 306 plan base station 302 to the mobile device 304. Additionally, the assignment from block 306 plan may include the value of C/I for the data transmission channel assigned to the mobile device 304, DataCtoIassigned. This value was selected based on the completion of the target HARQ. According to one aspect of the present disclosure, a reserved value DataCtoIassignedcan be used to instruct the mobile device to use them is the current value of the Delta on the alternation destination. In addition, the block 306 plan defines the maximum value of the increase in Delta (MaxDeltalncrease) and the maximum value of the reduction of the Delta (MaxDeltaReduction) for each class of quality of service (QoS). While these above-mentioned parameters (for example, DataCtoImin, DataCoTmin, DataCoTmax, DataCtoIassigned, step sizes, and so on) are assigned to the base station 304, it should be clear that the parameters should not be assigned using the same mechanisms or at the same time. For example, DataCoTmin, DataCoTmaxand the step size can be semi-static parameters, which should not be assigned for each service or destination. These parameters can be updated using the top-level messages or similar whenever an update is necessary.

[0044] These values can be used by the mobile device 304 in the decisions of management capacity. For example, these parameters can be used to set the destination range Delta transfer. This range can be defined in many ways. According to one aspect, an explicit value DataCtoIminand DataCtoImaxcan be assigned and used for the installation of this range. In addition, the relative boundary can be used, for example, through the parameters that define the maximum decrease or increase in the values of the deltas is or f/I. By way of illustration can be used the parameters MaxDeltalncrease and MaxDeltaReduction. According to another illustration, can be used is MaxCtoIIncrease and is MaxCtoIReduction. You must understand that combinations may also be possible (for example, MaxDeltalncrease and MaxCtoIReduction).

[0045] Block 306 plan allocates resources (channels, frequency, bandwidth, and so on) to mobile device 304. The base station 302 using block 306 plan, decides the destination based on various reviews. For example, the destination may trigger information downloaded through the channel request the return line (R-REQCH). The request may include the buffer size or the level of quality of service (QoS). In addition, the block 306 plan may base the decision assignment on feedback information received form the mobile device 304. Block 306 plan may take into account (calculated) adopted by the feedback information, such as the value of the slow Delta, which serves as the suggested values for future assignments. Feedback may additionally include a reserve power amplifier, display activity fast OSI, etc.

[0046] the base station 302 additionally includes block 308 broadcast OSI, which broadcasts information other sector interference to the mobile device in each the x sectors not serviced by base station 302. Each supercade base station 302 uses block 308 broadcast OSI to broadcast the importance of the regular OSI mobile device. The importance of regular OSI represents the average interference observed during the previous superquadra. It should be clear that it can be averaged more than one previous supercar. By means of example and not limited to, the value of the regular OSI may contain the mean interference observed during the previous three supercarb. In accordance with an aspect, the value of the regular OSI can veshatsa channel broadcasting, such as the pilot channel OSI direct lines of communication (F-OSICH). In addition, display regular OSI can be transmitted in the preamble of superquadra each superquadra. Power control based on the value of the Delta through the mobile device 304 based on the indication of the regular OSI from base stations in other sectors may lead to a dense distribution of interference in scenarios full buffer.

[0047] In situations of intermittent traffic may require a more dynamic management of power levels. Accordingly, the block 308 broadcast OSI also broadcasts the value of the fast OSI taken by the mobile device 304 and other mobile devices served by base station 302. Display fast OSI can veshatsa channel transfer fast what's OSI (F-FOSICH) on the segment control direct line of communication. By means of example and not limited to, reports fast OSI can be grouped in a collection of four bits each and each collection can be transmitted using six characters modulation, similar to the data transfer by the direct channel quality indicator pilot signal (F-PQICH). In this example, the erasing can be converted into a sequence of all zeros so that there was no indication fast OSI concerning any of the involved sub-bands. The value of the fast OSI can veshatsa for each subband at each alternation of each frame in the reverse link. The value of the fast OSI may be based on interference observed in a particular sub-band of a certain frame return line connection.

[0048] the base station 302 additionally includes block 310 broadcast offset interference. To reduce packet errors in the case of a large value exceeding the interference over thermal noise (IoT) increase due to the intermittent (pulsed) traffic in the adjacent sectors, the base station 302 using block 310 broadcast offset interference can use the quick reports IoT. Base station 302 can optionally use a block 306 plan to facilitate dynamic adjustment of the minimum Delta values for each assignment, as described here. Block broadcast offset p is the fur passes the value of the offset noise InterferenceOffsetsfor each subband. This value is based, at least in part, on the amount of interference observed by the base station 302 in the sub-band s, filtered by interleaving. This value can be passed by direct channel values exceeding the interference over thermal noise (F-IOTCH).

[0049] In addition to the above described reports the base station 302 can further transmit the quantized information about the adopted spectral power density (PSD) of the excess carrier signal over thermal noise (M) pilot-control signal for the mobile device 304, if active, and for all active mobile devices in a sector served by base station 302. This information can be transmitted over the F-PQICH. This information and the above described values can be used by the mobile device 304 when performing power control based on the value of Delta. According to the aspect of the present disclosure, the mobile device 304 supports and regulates the value of the slow Delta and the Delta value transfer.

[0050] the Value of Delta is the offset between PSD pilot control signal and the PSD of traffic. The Delta value associated with the accepted value of C/I (for example, DataCtoI) through PSD excess carrier signal over thermal noise (pCoT) control pilot signal and PSD exceed the recommended reading level of interference over thermal noise (IoT) traffic. For example, the Delta value can be displayed in the C/I data according to the following:

Δ=CoTdata-CoTcontrol

Δ=CoIdata+IoTdata-CoTcontrol

In accordance with this illustration, the value CoIdata is the excess carrier signal over thermal noise of the channel data or traffic. The value CoTcontrolis the excess carrier signal over thermal noise for the control channel, such as a value of the PSD (pCoT) of the transmission channel pilot signal received from the base station. Accordingly, the value of Delta, Δ, is the difference or offset between the values of the PSD management and traffic. CoTcontrolequivalent to the sum of the values of C/I channel data, CoIdataand the values exceeding the signal interference over thermal noise for channel data transmission, IoTdata. CoIdatacan be a value DataCtoI assigned to the mobile device base station, as described here. In addition, IoTdatamay be an interference offset value transmitted by the base station.

[0051] the Mobile device 304 supports and adjusts (sets) the value of Delta in accordance with the range of values of Delta. The range of Delta values is set by the mobile device 304 on the basis of the received information or broadcast information included in the assignment from the base station 302. For example, the mobile device 304 set is pouring the minimum value of the slow Delta, Δslow,minand the maximum value of the slow Delta, Δslow,maxon the basis of the following:

Values DataCoTminand DataCoTmax- the minimum value and maximum value, respectively, the values of the PSD of the excess carrier signal over thermal noise for channel traffic provided by base station 302 as part of the assignment. The pCoT valueRLSSis the PSD value is exceeded, the carrier signal over thermal noise for the pilot channel of the service sector reverse link. Thus, the mobile device 304 sets the range of values of the slow Delta on the basis of the indications, broadcast or assigned by base station 302.

[0052] the Mobile device 304 includes a block 312 estimate (calculate) the value of the slow Delta, which supports and regulates the value of the slow Delta, Δslow. Block 312 calculating the value of the slow Delta defines and regulates the value of the slow Delta on the basis of indications of the regular OSI broadcasting base station to another sector, similar to base station 302. Each supercade block 312 calculating the value of the slow Delta generates a set of control OSI. The set of control OSI is formed by applying a threshold to the configurations sectors straight line tie is, who can capture the mobile device 304. Additionally, a set of control OSI can be formed by applying a threshold to the values of the difference of the change (chandiff) other sectors. It should be clear that a separate set of control may be generated for the base stations of other sectors, broadcasting display fast OSI. The set of control fast OSI may be restricted to members of the active set of the mobile device 304. The sector contains a sector serving the opposite line of the mobile device 304, is not included in the set of control OSI. The set of control OSI includes sectors that can be affected by interference caused by mobile device 304. For each member of the set of control OSI block 312 calculate (estimate) the value of the slow Delta-computes the difference of the change. The difference changes based on the received power in relation to the pilot signal capture, at the same time taking into account the transmit power of each sector in the set of controls. Block 312 calculating the value of the slow Delta regulates the value of the slow Delta, on the basis of, in particular, the values of the regular OSI, we the members of the set of control OSI. Block 312 calculating the value of the slow Delta further consider the corresponding calculated values of the difference of the change, and tech is the future value of the slow Delta mobile device 304. The value of the slow Delta is regulated by constants so that this value does not fall below the value of minimum and does not exceed the maximum value. The mobile device 304 transmits the adjusted value of the slow Delta to the base station 302, the base station serves the opposite line. The passed value is used as the suggested values for future assignments, the base station 302.

[0053] the Mobile device 304 additionally includes block 314 calculate Delta transfer, which supports and regulates the Delta value transfer, Δτx. Block 314 calculate Delta transfer determines and changes the value of the Delta transmission, on the basis of indications fast OSI broadcasting base station to another sector, similar to base station 302. The adjustment can be performed for each subband, when display fast OSI are for each padepokan. After the appointment of the sub-band s, with explicit DataCtolassignedissued by block 306 plan base station 302, block 314 calculate the Delta values of the transmission sets the range for the value of Delta transfer. For each package (or subpackage), p, for transmission on the sub-band s, block 314 calculate the Delta values of the transmission sets the minimum value of Delta, Δmin,pand assigned or Maxi is the real value of Delta, Δmax,p, p, according to the following:

In accordance with this illustration, the value interferenceOffsetRLSS,sis the indication of the level of excess signal interference over thermal noise for subband s in the sector, the technician back line. This value is airing the base station 302 and received by the mobile device 304. The pCoT valueRLSSis PSD CoT pilot signal in the sector, the technician return line connection for the mobile device 304. Is DataCtolmin,pis the minimum value of C/I corresponding to the packet p. The mobile device 304 receives the value DataCtolassigned,pin appointment from block 306 plan in the base station 302. Block 314 calculate the value of Delta transmission uses the most recent (i.e., sestertii) values interferenceOffset and pCoT. Additionally, the value exceeding signal interference over thermal noise of a particular sector can be used by block 314 calculate the Delta values of the transmission if the channel that transmits the offset noise is erased for many intervals of the report.

[0054] After establishing a range for the value of Delta transfer, Δτxblock 314 calculate the Delta values of the transmission adjusts (sets) the value on the basis of indications fast OSI, broadcast neighboring sectors and adopted mobile is diversified devices 304. Initially, the value of Delta transfer is initialized equal to Δmaxas specified above. After initialization, the value of Delta transmission is controlled through a step-by-step increase or decrease values on the basis of the review meetings indications fast OSI. For re-transmission in the sequence, i, block 314 calculate the Delta values of the transmission adjusts the Delta value of the transmission in response to the indication of the fast OSI corresponding to the previous transmission of this alternation. The adjustment can be implemented according to the following:

In accordance with this example, the value fastOSIiis received indicating a fast OSI corresponding to the alternation, i. Values fastOSIStepUP and fastOSIStepDown is increased by the step value and reduced by the step value Delta transfer, respectively. Adjustment is done by block 314 calculate the Delta values of the transmission, with the limitation that the value of Delta transfer does not exceed the value of Δmaxand never falls below Δmin. For new packages or new assignments, which does not include an explicit value DataCtolassignedthe Delta value transfer is not initialized in Δmax. Instead, the block 314 calculate the value of Delta transmission uses the most recent value of Delta transfer and performs the same adjustment is, as explained above.

[0055] According to another aspect of the present disclosure, the mobile device 304 includes a block 316 adjustment PSD, which sets the PSD transfer assigned data channel return line connection (for example, R-DCH) for each destination. You must understand that the PSD transmission can be installed in each sub-band, when the value of Delta transfer and display fast OSI available for each subband. PSD transmission to the data transmission channel is established in accordance with the following:

In accordance with this illustration, j is the index of the subpackage and the values of the peaks (increase), AttemptBoostjare assigned to base station 302. The PSD valueR-PICHis the PSD of the pilot channel of the reverse link. If the resulting transmit power is greater than the maximum transmit power available for traffic, block 316 adjustment PSD scales PSD data so that the total transmission power is the maximum power transfer.

[0056] Additionally, in accordance with another aspect of the present disclosure, the mobile device 304 provides feedback to the base station 302. The mobile device 304 may send out-of-band reports and in-band reports. Out-of-band reports may include information regarding meant the th excess carrier signal over thermal noise or values of the difference changes. For example, mobile device 304 can transmit the maximum accepted value of Hundreds across the range. The value of a Hundred can be a indication of stock RA. This value can be calculated, using the feedback signal Hundred pilot signal received from the channel indication of the quality of the pilot signal a straight line. According to the example, this value is only after significant changes from the previous report. In addition, the mobile device 304 can tell the difference between the changes to the base station 302. Similarly communicated to the value of Hundreds, this value can be communicated only after significant changes.

[0057] In addition to the in-band request the mobile device 304 may communicate information regarding the power control. For example, the mobile device 304 may report the value of the stock amplifier is slow Delta or the Delta value of the transmission corresponding adjusted value. Similarly, out-of-band reports, these reports can be sent after significant changes from previous report.

Although for ease of description show the methods and describes how consistent is etelnost action must be understood and appreciated that these methods are not limited to actions, because some actions, in accordance with one or more variants of the implementation can take place in excellent order and/or concurrently with other actions to those shown and described in the present description. For example, specialists in the art will understand and appreciate that the method may be an alternative represented as a sequence of interacting States or events, such as the state diagram. In addition, not all illustrated steps may be required to implement a method in accordance with one or more variants of implementation.

The purpose, for example, may be a distribution of frequency resources or the value of the data channel return line connection on the mobile device. Parameters power control may include the minimum and the maximum value is exceeded, the carrier signal over thermal noise to the data transmission channel of the reverse link. In addition, the parameters of the power control may include assigned or target value C/I-specific sub-band, which must be assigned to the mobile device. Parameters power control may not be included in each assignment, since the quasi-static parameters can be assigned only when the settings need updating. At step 404 are assigned to the mobile device. Solution assignment can in particular be based on feedback information received form the mobile devices. Feedback may include Delta values (e.g., slow Delta and Delta values of the transfer), supply of the power amplifier, the buffer size, the level of QoS, the maximum allowable power based on alleged interference, and/or report an excessive activity of the fast OSI.

[0060] At step 406 is airing display regular OSI. Broadcasting may occur once every supercar, and the indication may be included in the preamble of superquadra. Display regular OSI is the average value of interference observed during the previous () supercade(s). This value facilitates the determination of the value of slow Delta. At step 408 is airing indication fast OSI. Broadcasting may occur for each subband in each frame of the reverse link. Indie is the situation fast OSI is interference, observed by some sub-band relative to a specific frame of the reverse link. Display fast OSI facilitates the determination of the value Delta transfer. At stage 410 is transferred to the offset value of the interference. The interference offset value is transmitted for each sub-band. This value represents the amount of interference observed on the specific sub-band, filtered through rotation. For example, the offset value of the interference may be IoT level sub-bands.

[0061] Below with reference to FIG.5 is illustrated a method 500 that implements the power control reverse lines of communication with the wireless connection. The method 500 may be used by the mobile device for, among other things, the generation of the slow Delta used by the base station for future decisions of destination. At step 502 determines the range for the value of the slow Delta. This range may be based on parameters included in the assignment. For example, the range may be based on considerations of the minimum and maximum values of the Cells included in the assignment, as well as PSD pilot channel. This range defines the minimum and maximum values for the value of the slow Delta so that the setting (adjustment) to the value of the slow Delta are limited within the range. This knowledge is to be placed may also be included in the previous assignment, not the most recent. For example, some parameters may be semi-static and require only periodic updates. At step 504 is slow Delta compute or regulate (adjust). This value is calculated on the basis of regular meetings OSI from members of the set control. In addition, the difference changes, the corresponding members of the set of control, as well as the current value of the slow Delta, can be considered. At step 506 is transmitted adjusted value of the slow Delta. This value can be transmitted to the base station serving the opposite line of the mobile device, for use in future decisions of the destination.

[0062] Below with reference to FIG.6 illustrates a method 600 that implements the power control of the reverse link. The method 600 may be used by the mobile device in the wireless communication system to install PSD for channel reverse traffic link. At step 602 sets the range for the value of Delta transfer. This range may be based on the values included in the assignment. In addition, the range can be determined based on the reviews of the offset values of interference, as well as the Hundreds of the pilot channel. At step 604, the value of Delta transfer calculate or adjust. The adjustment can be based on the broadcast is of ndicate fast OSI. For example, the Delta value may be initialized equal to the maximum value and then adjusted up or down by using a specified step size depending on indications fast OSI. Indication of increased interference in other sectors usually leads to a reduction step down Delta values of the transmission at that time if there are indications that this may lead to an increase of the step up value of the Delta gear. At step 606 sets the spectral power density channel of the reverse traffic link. PSD is set based on the value of Delta transfer. For example, in accordance with an aspect of the present disclosure, the PSD of the channel traffic is set equal to the sum of the PSD of the channel transmitting the pilot signal and the Delta values of the transmission. In addition, the assigned value increase can be included in the sum.

Although depicted which is separate from the processor 706, it is necessary to understand that the block 710 calculate the value of slow Delta, block 712 calculate the Delta values of the transmission, the controller 718 PSD and/or modulator 714 can be part of processor 706 or multiple processors (not shown).

[0070] FIG.8 illustrates a system 800 that facilitates the management capacity of the return line by giving information related to power control on the mobile device in a wireless communications system. The system 800 includes a base station 802 (e.g., access point,...) with receiver 810 that receives signal(s) from one or more mobile devices 904 through multiple antennas 806, and the transmitter 820, which transmits one or more mobile devices 804 via the antenna 808 transmission.

[0073] FIG.9 shows a system 900 wireless example. The system 900 wireless depicts one base station 910 and one mobile device 950 for the sake of brevity. However, it should be understood that the system 900 may include more than one base station and/or more than one mobile device, and additional base stations and/or mobile devices can be essentially the same or different from the exemplary base station 910 and the mobile device 950, described below. In addition, you must understand that the base station 910 and/or mobile device 950 can use system (FIG.1-3 and 7-8) and/or methods (FIG.4-6), described in the present description to facilitate wireless communication between them.

[0074] In the base station 910 traffic data for a set of data streams issued from a data source 912 processor 914 transmission (TX) data. According to the example, each data stream may be transmitted by the corresponding antenna. Processor 914 transmission (TX) data formats, encodes, and Premia is t the flow of data traffic based on a particular coding scheme, selected for data flow for issuance of coded data.

[0075] the Coded data for each data stream may be multiplexed with pilot data using methods of multiplexing orthogonal frequency division (OFDM). Additionally or alternatively, the pilot symbols may be multiplexed by frequency division (FDM), multiplexed with the separation time (TDM) or multiplexed code division (CDM). The pilot data is typically a known data sample, which is processed in a known manner and can be used in a mobile device 950 to assess the response of the channel. The multiplexed pilot and coded data for each data stream may be modulated (for example, a character converted) based on a particular modulation scheme (e.g., binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), M-phase-shift keying (M-PSK), M-quadrature amplitude-shift keying (M-QAM), and so on), the selected data stream to transmit the modulation symbols. The data rate, coding and modulation for each data stream may be determined by instructions executed or issued by the processor 930.

[0076] the modulation Symbols for the data streams may be issued on the processor 920 MIMO transmission TX, which could critique the sustained fashion to process the modulation symbols (e.g., for OFDM). The processor 920 MIMO transfer TX data then gives Ntstreams of modulation symbols for Nttransmitters (TMTR/RCVR) 922a-922t. In a different implementation, the processor 920 MIMO transfer TX data applies the weight of the beam forming the symbols of the data streams and to the antenna from which the symbol.

[0077] Each transmitter 922 receives and processes a respective symbol stream to issue one or more analog signals, and additionally results in the required conditions (e.g., amplifies, filters and converts with increasing frequency) analog signals for issuing a modulated signal suitable for transmission over the MIMO channel. Additionally, the modulated signals from the Nttransmitters 922a-922t transmitted from the NRantennas 924a-924t, respectively.

[0078] In the mobile device 950 transmitted modulated signals are received by NRantennas 952a-952r, and the received signal from each antenna 952 is issued to the appropriate receiver (TMTR/RCVR) 954a-954r. Each receiver 954 results in the required conditions (e.g., filters, amplifies and converts with decreasing frequency) corresponding signal, switches, refer to the specific requirements of the signal into digital form for delivery of samples and further processes these samples to issue a corresponding "received"symbol stream.

[0079] the Processor 960 receiving RX data can receive and process the received NRcharacter streams from the NRreceivers 954,,on the basis of specific processing method of the receiver to issue "identified" Ntcharacter streams. The processor 960 receiving RX data may demodulate, to perform a reversed interleaving and decoding of each detected symbol stream to recover the traffic data for the data flow. The CPU 960 receiving RX data is complementary to the processing performed by the processor 920 MIMO transmission TX and processor 914 transfer TX data to the base station 910.

[0080] the Processor 970 may periodically determine the matrix pre-encoding to use, as discussed above. Additionally, the processor 970 may formulate a message back line containing part of the index matrix and part of the estimated values.

[0081] the Message back to the communication line may contain various types of information regarding the communication line and/or the received data stream. Message return line may be processed by processor 938 transfer TX data, which also receives traffic data for multiple data streams from a source 936 data modulated by the modulator 980 given to the specific requirements of transmitters 954a-954r and passed called the d to the base station 910.

[0082] In the base station 910 modulated signals from a mobile device 950 accepted antennas 924, given to the specific requirements of receivers 922, demodulate the demodulator 940 and processed by the processor 942 receiving RX data to retrieve the message back line, transferred to the mobile device 950. Additionally, the processor 930 may process the extracted message to determine the matrix pre-coding be used to determine the weights of the beam forming.

[0083] the Processor 930 and 970 can control (for example, manage, coordinate, organize, and so on) at the base station 910 and the mobile device 950, respectively. The corresponding processors 930 and 970 may be associated with memory 932 and 972, which stores codes and program information. Processors 930 and 970 can also perform calculations to obtain the frequencies and the estimation of the impulse response for uplink communication and downlink, respectively.

While these above-mentioned parameters are assigned to the base station 80, you must understand what settings do not require the appointment through the same mechanisms or the same time. For example, step sizes and minimum/maximum values of the Honeycomb can be semi-static parameters, which do not require the assignment for each package or destination. These parameters can be updated by means of top-level messages or similar whenever an update is necessary. Additionally, logical grouping 1002 can include an electrical component for broadcasting values 1006 offset interference.

SUBSTANCE: invention relates to communication. Present invention discloses a method of configuring transmission power of a demodulation reference signal (DMRS) which comprises a step of configuring the ratio between transmission power of a DMRS at each layer in a resource element (RE) and transmission power of data at a corresponding layer in a RE to be a constant value. Furthermore, the present invention discloses an apparatus for configuring transmission power for the DMRS. The present invention greatly improves the rate of correct data frame decoding, and improves decoding performance. The present invention enables the network side to avoid the need to notify user equipment (UE) on the corresponding relationship between transmission power of DMRS at each layer and transmission power of data at the corresponding layer, which reduces the overhead of the control signalling at the network side. Since the corresponding relationship between transmission power of DMRS at each layer and transmission power of data at the corresponding layer is configured in the UE, the UE can implement channel estimation without waiting for the notification from the network side, which improves the channel estimation efficiency.

SUBSTANCE: in one aspect, power control (PC) is supported in several PC modes such as "up-down" PC mode and delete-based PC mode. One PC mode may be selected for use. Overhead may be sent to indicate the selected PC mode. If the "up-down" PC mode is selected, a base station assesses the quality of the received signal for the terminal and sends PC commands to instruct the terminal to adjust its transmission power. If the delete-based PC mode is selected, the base station sends delete indicators which indicate whether code words received from the terminal are deleted or not. In both PC modes, the terminal controls its transmission power based on a power control feedback (e.g. PC commands and/or delete indicators) in order to attain the desired level of efficiency (e.g. desired delete frequency for code words). Delete indicators may also be used for handover.
