Method of sending dispatching request in mobile communication system and terminal device to this end

FIELD: information technology.

SUBSTANCE: radio resource management unit gives a priority for retransmitting a dispatching request and repeatedly transmits the priority over a downlink. A terminal repeatedly transmits the dispatching request when the highest priority included in the dispatching request which must be transmitted is lower than the least priority for repeated transmission of the dispatching request. Alternatively, the radio resource management unit sets cycles (timers) for repeatedly transmitting dispatching requests in accordance with priorities and transmits the cycles over the downlink. The terminal does not repeatedly transmit the dispatching request before the cycle (timer), corresponding to the highest priority included in the dispatching request, finishes after the dispatching request is initially transmitted or repeatedly transmitted.

EFFECT: preventing inefficient consumption of radio resources and inefficient consumption of the power of the terminal, elimination of excessive noise.

The technical field

The present invention relates to a method and apparatus for transmission of request scheduling in uplink communication in a mobile communications system.

The level of technology

The multiplexing scheme used in wireless communication, can be divided into scheme multiplexing time division channels, the scheme of multiplexing, code division multiplexing, the multiplexing scheme with orthogonal frequency division multiplexing, etc. multiplexing Scheme, the most widely used today, is the scheme of multiplexing, code-division multiplexing, which, in turn, is divided into a synchronous circuit and the asynchronous circuit. However, the scheme of multiplexing, code-division multiplexing suffers from a lack of resources, because it is based uses codes, and thus, the orthogonal codes is not enough. Consequently, the scheme of multiplexing orthogonal frequency division multiplexing (hereinafter OFDM) is now in the spotlight.

OFDM scheme, one of the transmission schemes using a variety of bearing is a type of modulation scheme with many carriers (hereinafter MCM)in which a serial stream of input symbols is converted into parallel sub-characters, converted sub-symbols is delirous using multiple subcarriers (i.e. many sub-channels orthogonal to each other, and then modulated streams of characters transmitted. OFDM is a scheme similar to the scheme of multiplexing frequency division multiplexing (hereinafter FDM), but is different from the FDM schema that orthogonality between multiple subcarriers is maintained during transmission, and the frequency spectra are overlapping way. Thus, the OFDM scheme is effective when using frequencies that are resistant to frequency selective fading and multipath fading, and can reduce the effect of intersymbol interference (hereinafter referred to as "ISI") through the use of a guard interval. Additionally, the OFDM scheme can provide optimal transfer, effective for high-speed data transmission because it gives an opportunity to design the structure of the equalizer in the hardware and has the advantage of high resistance to impulse noise.

3GPP Partnership project third generation) is currently discussing the mobile communication system of the next generation as a replacement system universal mobile services (hereinafter UMTS), which is the standard for mobile communication of the third generation. This system next generation mobile system called Long-term evolution (LTE next).

Referring to Figa, user equipment (hereinafter referred to as UE) 11 is a terminal for the system, 3GPP LTE, and developed the radio access network (hereinafter E-RAN) 14 - this equipment is a base station participating in the communication with the terminal in the existing 3GPP system. E-RAN 14 acts not only as a node B to control cells, but also as a radio network controller (hereinafter RNC) for managing the set of nodes B and radioresource. In this respect, the E-RAN 14 may include the evolved node B (hereinafter E-NB) 12 and developed RNC (hereinafter E-RNC) 13, which are physically separated on different nodes in the existing 3GPP system, or integrated in a single unit. As an example, this paper assumes that the E-NB 12 and E-RNC 13 is physically integrated in a single unit. Nevertheless, it is obvious that the present invention can be applied in the same way, even if the E-RNC 13 is physically separated from the E-NB 12.

Developed core network (hereinafter E-CN) 15 - this is a site that combines the functions of the serving GPRS support node (hereinafter SGSN) and gateway GPRS support node (hereinafter GGSN) in the existing 3GPP system. E-CN 15 is placed between the packet data network (hereinafter PDN) and the E-RAN 14 and serves as the gateway for the destination address, an Internet Protocol (hereinafter IP) for the UE 11 and the UE connection 11 with PDN 1. Because the definitions and functions of the SGSN and GGSN follow the standards specified in 3GPP, their detailed description is omitted in this document.

Referring to Figv, the developed network of the UMTS radio access (hereinafter E-RAN) 110 has a simplified structure with two nodes of the evolved node B (hereinafter E-NB) 120, 122, 124, 126, 128 and anchor node 130, 132. The user equipment (hereinafter UE or terminal) 101 is connected to the IP network via the E-RAN 110. Each E-NB 120-128 corresponds to an existing node B UMTS system and connected to the UE 101 via radio. In contrast to the existing node B, E-NB 120-128 perform more complex functions. In the LTE system, since all user traffic including provided real-time services over IP, such as service voice-over-IP (hereinafter VoIP)service through a shared channel that requires the device to collect and scheduling information of the UE location. E-NB 120-128 function of such a device.

In General, one E-NB manages many hundreds, and adaptive modulation and coding (hereinafter AMC) to determine the modulation scheme and the speed channel coding in accordance with the channel state of the UE is in E-NB. Additionally, similar packet access high speed downlink (hereinafter HSDPA) or packet access high speed uplink communication (HSUPA), also known as separation of the th channel enhanced uplink communication (or E-DCH) UMTS-system, LTE-a system uses a hybrid automatic request for retransmission (hereinafter HARQ) between E-NB 120-128 and UE 101. However, because of different requirements for quality of service QoS) cannot be satisfied only through HARQ, the upper level can execute a separate ARQ (hereinafter outer ARQ), which is also performed between the UE 101 and the E-NB 120-128. HARQ refers to methods of increasing the frequency of successful techniques by soft combining the re-transmitted data with the previously accepted data without discarding the previously received data and is used to improve the transmission efficiency in high-speed packet communication, such as HSDPA. In order to transmit a maximum of 100 Mbps, the LTE system is expected to use OFDM scheme as a radio access technologies with a bandwidth of 20 MHz.

Figure 2 illustrates the procedure in which the UE transmits the request dispatching or report the status of the buffer in the E-NB technology HSUPA 3GPP.

If data or control signals that must be transmitted by the UE, are formed when resources are not allocated to the UE, the UE transmits the request dispatching or report the status of the buffer in the E-NB to request E-NB to allocate radioresource data or control signals.

Request dispatching and report status buffer distinguish the I from each other only by name and in fact, are the same. I.e. they correspond to the procedure of the message in the E-NB information about the priorities of data or control signals that must be transmitted, the amount of data or control signals according to the priorities, filled in the buffer, etc. to request E-NB to allocate radioresource data or control signals in the uplink communication. After receiving the request dispatching or report the state of the buffer from the UE, the E-NB allocates radioresource for the UE. In the present invention, the request dispatching is abbreviated as SR, and report the status of the buffer is reduced as the BSR. SR or BSR can be transmitted through the service signals PHY (physical layer) or official signals the MAC (media access).

Referring to Figure 2, if data or control signals, which must be passed, are formed in each of the UE#1, UE#2, ..., UE#N 201, 202, 203 by means of the upper level, each of the UE#1, UE#2, ..., UE#N 201, 202, 203 transmits the SR/BSR 231, 232, 233 in the E-NB 211. After receiving the SR/BSR 231, 232, 233 from the UE, the E-NB 211, usually allocates radioresource each of the UE#1, UE#2, ..., UE#N 201, 202, 203, when the honeycomb radio resource is not loaded. Radioresource allocated to each UE#1, UE#2, ..., UE#N 201, 202, 203, determined by information included in the SR/BSR 231, 232, 233, transmitted from each of the UE, i.e. the respective priorities of the data or control signals, who should be transferred, amounts of data or control signals according to the priorities, filled in the buffer.

In figure 2, the requested radioresource cannot be allocated to the UE, since the honeycomb loaded resources, as indicated by reference number 221. If the E-NB 211 accepts the SR/BSR 231, 232, 233, but cannot allocate radioresource all of the UE#1, UE#2, ..., UE#N 201, 202, 203, the UE identifiers and information selection radioresource not included in the information dispatch transmitted in downlink. If the UE 201, 202, 203 may not be highlighted radioresource for transmission on the uplink communication of the information dispatch transmitted over the downlink after the transmission of the SR/BSR 231, 232, 233, they retransmit the SR/BSR 241, 242, 243 in the E-NB 211. This is done under the assumption that the E-NB 211 can't take the SR/BSR 231, 232, 233, transmitted by UE. However, at the moment in time when the UE re-transmits the SR/BSR 241, 242, 243 after the transmission of the SR/BSR 231, 232, 233, information about the priorities of data or control signals that must be transmitted, the amount of data or control signals according to the priorities, filled in the buffer may vary, and thus the SR/BSR 241, 242, 243 may include values other than the values in the SR/BSR 231, 232, 233.

Although E-NB 211 accepts the SR/BSR 241, 242, 243, it may not allocate radioresource for transmission on the uplink communication, the requested what exploits UE#1, UE#2, ..., UE#N 201, 202, 203, since the honeycomb loaded radio resource as the time when the E-NB 211 accepts the SR/BSR 231, 232, 233. If the UE identifiers and information selection radioresource not included in the information dispatch transmitted in downlink after the SR/BSR 241, 242, 243 transmitted, the UE can know that radioresource for transmission on the uplink communication is not selected.

If UE#1, UE#2, ..., UE#N 201, 202, 203 may not be highlighted radioresource for transmission on the uplink connection after sending the SR/BSR 241, 242, 243, they retransmit the SR/BSR 251, 252, 253 in the E-NB 211. If the E-NB 211 does not emit radioresource for UE even after receiving the SR/BSR 251, 252, 253, UE 201, 202, 203 retransmit the SR/BSR 261, 262, 263 in the E-NB 211. I.e. if the UE cannot be selected radioresource for transmission on the uplink connection after sending the SR/BSR, they repeatedly transmit the SR/BSR. However, when the E-NB 211 does not emit radioresource for transmission on the uplink communication UE not because he can't take the SR/BSR, but because honeycomb loaded radio resource regardless of successful reception of the SR/BSR, not only repeating the SR/BSR 241, 242, 243, 251, 252, 253, 261, 262, 263 not applied, but also can be caused by many problems, including inefficient consumption radioresource and the power consumption of the UE, as well as unnecessary interference.

A detailed description of the preferred embodiments

The following describes preferred embodiments of the present invention with reference to the accompanying drawings. It should be noted that similar components are denoted by similar numbers of reference, although they are illustrated in different drawings. In addition, in the following description, a detailed description of known functions and configurations contained in this document is omitted for purposes of clarity and brevity. Additionally, it should be noted that only the parts essential for understanding the operations according to the present invention, the op is studying, and description of parts, non-essential parts, is also omitted for brevity.

According to the first variant implementation of the present invention to prevent unnecessary transmission or re-transmission of the SR/BSR, E-NB informs the UE in the lowest priority on the downlink. The lowest priority means the least of the priorities included in the SR/BSR, for which radioresource successfully isolated from the SR/BSR, received via E-NB. When each UE transmits or retransmits the SR/BSR, it compares the lowest priority highest priority priority included in the SR/BSR to be transmitted or re-transmitted, and determines whether to transmit or retransmit the SR/BSR, based on the comparison result. I.e. E-NB optimizes the transmission/retransmission SR/BSR by prohibiting useless transmission or re-transmission of the SR/BSR.

Figure 3 illustrates the mode of transmission/retransmission SR/BSR according to the first variant implementation of the present invention.

Referring to Figure 3, if data or control signals that must be transmitted in uplink communication, are formed in the UE 301 through the upper level and transmitted to the transmit buffer, the UE 301 transmits the SR/BSR 321 in the E-NB 311 to request E-NB 311 to allocate radioresource data or control signals. SR/BSR 321 incl is no information on the priorities of the services under unidirectional radio, relevant information such as data or control signals and the amount of data or control signals. If the data and control signals are transmitted together in the transmit buffer or the data corresponding to the various applications that are transmitted together in the transmit buffer, the set of priorities associated with the relevant data or control signals may be included in the SR/BSR. In this case, the SR/BSR includes information on the volume of data or control signals according to the priorities, starting with the highest priority. Figure 3 assumes that the highest priority included in the SR/BSR 321 is "X".

Next, the E-NB 311 transmits an alert 331 of the lowest priority, i.e. the criteria for permitting transmission of the SR/BSR, on the downlink in the UE within a cell. As an example, the lowest priority for permitting the transmission of the SR/BSR can be set taking into account the radio resource control (hereinafter RRM) and the lowest priority included in the SR/BSR, for which radioresource successfully allocated, the SR/BSR, which E-NB 311 previously received from the UE within the corresponding cell. For example, when significant resources remain, the SR/BSR from all UE can be resolved by setting the lowest priority for permitting the transmission of the SR/BSR, which is transmitted in the UE, is equal to 1 (or 0), while the lowest priority for allocation radioresource in radiusim TTI is equal to 6.

The lowest priority for permitting the transmission of the SR/BSR (next lowest allowed priority), which is transmitted through the alert 331, allows UE within a cell to control the transmission of the SR/BSR.

Ie UE 301 compares the minimum priority that is included in the alert 331, with the highest priority from the priority services, the relevant data or control signals transmitted in the transmit buffer by means of the upper level, which are included in the SR or BSR, which must be passed. If the comparison result shows that the highest priority of the priority of services is less than the minimum allowed priority, the UE 301 does not perform retransmission SR/BSR, because E-NB 311 does not emit radioresource, even if the UE 301 re-transmits the SR/BSR. On the contrary, if the highest priority equal to or greater than the highest allowed priority, the UE 301 re-transmits the SR/BSR. The lowest priority may be cyclically transmitted on the common channel. As an example, in this document it is assumed that the lowest priority, together with information dispatch (hereafter SI) for a message UE within a cell information selection radioresource for transmission on the uplink communication is transmitted in each cupcake (here Subcat is the minimum allocation unit radioresource for transmission on the uplink communication in the UE, and information of the allocation radioresource for transmission on the uplink communication may be sent to the UE in each cupcake on the General channel. However, the present invention does not exclude the schema in which the lowest priority cyclic or acyclic transmitted via a dedicated channel assigned to each UE, and not on the General channel. Figure 3 assumes that the lowest allowed priority included in the notification 331 is "Y".

If the UE 301 transmits the SR/BSR 321 in the E-NB 311, but E-NB 311 does not emit radioresource for transmission on the uplink communication in the UE 301, the UE 301 compares the minimum allowed priority Y, recently notified by E-NB 311, with the highest priority X included in the SR/BSR 321, which must be passed, as indicated by reference number 341. If X is less than Y (X<Y), the UE 301 does not perform retransmission SR/BSR.

Reference number 332 indicates that the lowest priority for permitting the transmission of the SR/BSR cyclically transmitted via E-NB 311, and the reference number 342 indicates that the UE 301 receives cyclically transferred to the lowest priority Y and compares it with the highest priority included in the SR/BSR, which must be passed.

Figure 3 smallest permitted priority continuously transmitted from the E-NB 311 in the UE 301 through alerts 332-351. Meanwhile, 301 does not perform retransmission SR/BSR, as sent to the lowest priority Y still more highest priority for X SR/BSR.

However, if the minimum allowed priority is changed from Y to Z due to a change in state of the load cell, UE 301 compares the highest priority for X SR/BSR, which must be passed with a modified minimum priority Z, as indicated by reference number 361.

If the comparison result shows that X is equal to or greater than Z, UE 301 re-transmits the SR/BSR 371 E-NB 301. E-NB 311 allocates radioresource for transmission on the uplink communication in the UE 301 and transmits SI on downlink by using information included in the SR/BSR 371, as indicated by reference number 372.

Additionally, when you are configuring or reconfiguring a unidirectional channel in order to receive a particular service, E-NB specifies the priority of the logical channel MAC logical channel corresponding to a particular service, thus, to coincide with the service and informs the UE specified priority logical channel MAC, thereby providing synchronization of priority between E-NB and UE.

In figure 3, when data or control signals are formed through the upper layer and thus the SR/BSR must be submitted in order to request the allocation of resources for uplink communication, the UE is allowed to initially transmit the SR/BSR, but it can retransmit the SR/BSR, when the highest priority SR/BSR is equal to or larger than the lowest priority for permitting the transmission of the SR/BSR, which is communicated down the line p which means E-NB. In other words, when E-NB does not emit radioresource for the appropriate transfer of upward communication in the UE (i.e. the ID of the UE and information selection radioresource not included in the SI taken from the E-NB) after the initial transmission of the SR/BSR, and thereby the UE shall re-transmit the SR/BSR, only the SR/BSR, which includes the highest priority that is equal to or larger than the lowest priority notified by E-NB, can be resubmitted.

Although not illustrated in Figure 3, the lowest priority for permitting the transmission of the SR/BSR, which communicates via a downlink via E-NB, can be applied in order to form the initial SR/BSR. I.e. should I send the initial SR/BSR, can be defined by the first definition, equal to or greater than the lowest priority highest priority included in the initial SR/BSR.

Additionally, although not illustrated in Figure 3, the permitted level of class UE/user or allowed data rate for services can be used in alerts 331, 332 and 351 instead of using the lowest priority for permitting the transmission of the SR/BSR. In this case, the SR/BSR is transmitted only when the level of the class UE or the user sending the SR/BSR, equal to or more than the permitted level class UE/user, and is not transmitted, when the level of the class UE or user is on of the motor is less than the permitted level class UE/user. Similarly, the SR/BSR is transmitted only when the target data rate for services SR/BSR equal to or less than the allowed data rate for services, and is not transmitted, when the target data rate for services is more than the allowed data rate for services. Additionally, the priorities of the services included in the SR/BSR, can be used in combination with the permitted level of class UE/user and allowed data rate for services, for example.

Figa and 4B illustrate the operation of the UE according to the first variant implementation of the present invention. From these two drawings Figa relates to a method for managing re-transmission of the SR/BSR through the lowest priority without control the initial transmission of the SR/BSR, and Figv relates to a method of re-transmitting the SR/BSR, as well as the initial transmission of the SR/BSR through the lowest priority.

Referring to Figa, if data or control signals that must be transmitted in uplink communication, are formed through the upper level and transmitted to the transmit buffer at the step 401, and thereby the UE should transmit the SR/BSR, the UE sends an initial SR/BSR in the E-NB at step 402 and receives the grant channel resources from the E-NB in step 403. SI is transmitted over the channel resource allocation and UE within a cell can know through SI what radioresource in the divided what UE.

At step 411 UE that transmitted the SR/BSR, determines whether information selection radioresource for transmission on the uplink by the UE in SI adopted for the grant channel resources. If the information selection radioresource included in SI, the UE proceeds to step 421 and transmits data or control signals in the transmit buffer by using a dedicated radioresource. However, if the information selection radioresource for transmission on the uplink by the UE is not included in SI, adopted on the grant channel resources, the UE proceeds to step 422 and requests the lowest priority for permitting the transmission of the SR/BSR, which is cyclically transmitted on the downlink.

At step 431 UE determines what is the highest priority included in the SR/BSR transmitted at step 402, less than the lowest priority for permitting the transmission of the SR/BSR, adopted at step 422.

If the result shows that the highest priority included in the SR/BSR, less than the lowest priority for permitting the transmission of the SR/BSR, the UE returns to step 403 and accepts the grant channel resources. However, if the highest priority is not less than the lowest priority, the UE proceeds to step 442, re-transmits the SR/BSR, and then returns to step 403.

Referring to Figv, if data or control signals, which D. who should be transferred upward communication formed through the upper level and transmitted to the transmit buffer at step 451, and thereby the UE should transmit the SR/BSR, at step 452 UE receives the lowest priority for permitting the transmission of the SR/BSR, which is cyclically transmitted on the downlink from the E-NB. At step 461 UE compares the highest priority included in the SR/BSR transmitted at step 451, the lowest priority for permitting the transmission of the SR/BSR, obtained in step 452.

If the comparison result shows that the highest priority included in the SR/BSR, less than the lowest priority for permitting the transmission of the SR/BSR, the UE returns to step 451. However, if the highest priority is not less than the lowest priority, the UE proceeds to step 472, transmits (or resubmit) SR/BSR, and then accepts the grant channel resources at step 473.

At step 481 UE that transmitted the SR/BSR at step 472 determines whether information selection radioresource for transmission on the uplink by the UE in the grant channel resources, adopted at step 473. If the result shows that the information selection radioresource included in the grant channel resources, the UE proceeds to step 491 and transmits data or control signals in the transmit buffer by using a dedicated radioresource. However, if the information selection radioresource not included the in the grant channel resources UE returns to step 452.

Figure 5 illustrates the E-NB according to the first variant implementation of the present invention.

Referring to Figure 5, if the cycle in which the lowest priority for permitting the transmission of the SR/BSR transferred, is fed to step 501, in step 511, E-NB specifies the lowest priority for permitting the transmission of the SR/BSR through consideration of the least of the priorities included in the SR/BSR, for which radioresource successfully isolated from the SR/BSR, which E-NB already received from the UE within a cell, RRM to control the state of the load cell and other factors. At step 521 E-NB transmits the lowest priority for permitting the transmission of the SR/BSR specified at step 511, down the line at a desired time by using a specified channel.

6 illustrates the structure of a UE according to the first variant implementation of the present invention.

Referring to Fig.6, the UE includes the top level 601, block 611 buffer Manager data service signals unit 621 of the transceiver unit 631 determine transmission (retransmission) SR/BSR and the timer 641. The upper level 601 includes an upper control unit for generating control signals and the upper application unit to generate the data.

Data or control signals generated at the top level 601 are transmitted in a transmission buffer (not shown). If the buffer is re the ACI filled with data or control signals, transferred from the upper level, 601, block 611 buffer Manager data service signals transmits the SR/BSR in the E-NB through the block 621 transceiver to request E-NB to allocate radioresource for transmission on the uplink communication. Using the signal channel provisioning, take in downlink through block 621 transceiver after the transmission of the SR/BSR, the UE determines the selection radioresource for transmission on the uplink by the UE. If radioresource for transmission on the uplink by the UE is allocated, the UE transmits data or control signals in the transmit buffer by using a dedicated radioresource. However, if radioresource for transmission on the uplink by the UE is not allocated, the block 631 define the transfer of SR/BSR determines whether to retransmit the SR/BSR, on the basis of the lowest priority for permitting the transmission of the SR/BSR, which is received in downlink through block 621 transceiver. By definition, the module 631 define the transfer of SR/BSR re-transmits the SR/BSR or continue to accept the grant channel resources and the lowest priority for permitting the transmission of the SR/BSR, which is cyclically transmitted on the downlink. As described in connection with Figure 3, the module 631 define the transfer of SR/BSR determines the Torno to transmit the SR/BSR, only when the highest priority included in the SR/BSR, which must be re-transmitted, is equal to or larger than the lowest priority for permitting the transmission of the SR/BSR passed down the line. The timer 641 defines a loop which is passed to the lowest priority for permitting the transmission of the SR/BSR.

Although not illustrated in Figure 3, even when the initial transmission of the SR/BSR managed by using the lowest priority for permitting the transmission of the SR/BSR, as already described, the lowest priority for permitting the transmission of the SR/BSR taken down the line through the block 621 transceiver before the initial SR/BSR transmitted, and the module 631 define the transfer of SR/BSR uses adopted the lowest priority to determine whether to transmit the initial SR/BSR. Additionally, based on the determination unit 621 transceiver transmits the initial SR/BSR or does not perform retransmission SR/BSR and continues to be the lowest priority for permitting the transmission of the SR/BSR, which is cyclically transmitted.

7 illustrates the structure of the E-NB according to the first variant implementation of the present invention.

Referring to Fig.7, the E-NB according to this variant implementation includes the timer 701, block 721 transceiver and block 711 determine the lowest priority.

The timer 701 defines a loop in which descending Lin and communication is sent to the lowest priority for permitting the transmission of the SR/BSR. Block 711 determine the lowest priority specifies the lowest priority for permitting the transmission of the SR/BSR through consideration of the least of the priorities included in the SR/BSR, for which radioresource successfully isolated from the SR/BSR, which E-NB already received from the UE within a cell, or condition of the load cell. Block 721 transceiver cyclically transmits the lowest priority for permitting the transmission of the SR/BSR specified by block 711 determine the lowest priority for downlink to the UE through the corresponding channel.

In the above-mentioned first embodiment of the present invention lowest priority, reported on the downlink to the UE, compared with the highest priority included in the SR/BSR, but the level of class UE/user or the data rate for services, which must be requested, may be compared with the permitted level of class UE/user or allowed data rate for services.

In the second embodiment of the present invention timers retransmission according to the priorities set. If the requested radioresource not allocated after the SR/BSR originally passed, the SR/BSR resubmitted after the time specified by the timer retransmission corresponding to the highest priority of priorities included the x in the SR/BSR, which must be passed. Thus, the SR/BSR with a lower priority are transmitted relatively less often than the SR/BSR with higher priority, so that retransmission of the SR/BSR can be optimized.

Fig illustrates the procedure for re-transmitting the SR/BSR according to the second variant of implementation of the present invention.

Referring to Fig, as indicated by reference number 821, UE 801 within a cell requests information cycle (timer for re-transmitting the SR/BSR, which is defined according to the priorities. The cycle information can be transferred via the system information transmitted in the broadcast mode within a cell transmitted from the UE to the UE through the service signals or pre-established between the UE 801 and E-NB 811 by implicit rules. If the information cycle preset by implicit rules, it can be implemented as hard coding in the UE. Although the present invention is not limited to a specific scheme for Pig it is assumed that the UE 801 requests information cycle through system information.

If data or control signals that must be transmitted in the ascending line, are formed in the UE 801 through the upper level and transmitted to the transmit buffer, the UE 801 transmits the SR/BSR 831 E-NB 811 and starts the cycle (timer)corresponding to the highest priority list of the etu, included in the SR/BSR 831, through the use of the requested information cycle according to the priorities. I.e. provided on Fig that the highest priority included in the SR/BSR 831 is "X", cycle (timer)corresponding to X, start.

If the UE 801 receives the grant channel resources after sending the SR/BSR 831, but cannot be selected radioresource for UE 801 through SI, adopted during the cycle of re-transmitting the SR/BSR corresponding to the highest priority X, it re-transmits the SR/BSR, when the cycle (timer) retransmission expires and resets the retransmission timer, as indicated by reference number 832. If the UE 801 cannot be selected radioresource even during the second cycle of re-transmission, it re-transmits the SR/BSR, when restarted the timer expires, as indicated by reference number 833. I.e. if radioresource for UE 801 is not selected, UE 801 performs retransmission according to the information cycle corresponding to the highest priority included in the SR/BSR.

The cycle of re-transmission can be set differently according to the priorities. I.e. the longer the cycle of re-transmission is set for the SR/BSR with a relatively low priority, so that the SR/BSR transmitted less often and shorter cycle re-transmission is set for the SR/BSR with a relatively high priority, so that the SR/BSR before the was more often. Thus, the re-transmission of the SR/BSR can be optimized.

Although not illustrated in Fig, you can also start the cycle (timer) retransmission corresponding to the highest priority X, not when UE 831 transmits the SR/BSR, and when the UE 801 determines that it received the grant channel resources, but it cannot be allocated resources for the UE 801 through SI.

Additionally, the highest priority included in the SR/BSR, can be changed in the process of re-transmitting the SR/BSR, and then UE 801 re-transmits the SR/BSR according to the cycle of re-transmission, the corresponding modified the highest priority.

Fig.9 illustrates the UE according to the second variant of implementation of the present invention.

Referring to Fig.9, if data or control signals that must be transmitted in the ascending line, are formed through the upper level and transmitted to the transmit buffer at step 901, and thereby the UE detects the need to transfer the SR/BSR, the UE transmits the SR/BSR in the E-NB in step 902. Additionally, using the information cycle (timer) re-transmission according to the priorities that have already requested through system information or a service signals according to the UE, the UE starts the cycle (timer) retransmission corresponding to the highest priority included in the SR/BSR transmitted at step 902.

Next, the UE receives the channel pre is leaving resources in step 903. At step 911, using SI included in the received channel resources, the UE determines the selection radioresource for the UE. If radioresource allocated for the UE, the UE proceeds to step 921 and transmits data or control signals in the transmit buffer by using a dedicated radioresource. However, if radioresource for the UE is not allocated, the UE proceeds to step 931 and determines expired if the cycle (timer)running on stage 902. If the cycle (timer) has not expired, the UE returns to step 903. However, if the cycle (timer) has expired, the UE proceeds to step 941 and re-transmits the SR/BSR, starts the cycle (timer) retransmission corresponding to the highest priority included in the retransmitted SR/BSR, and then returns to step 903.

Figure 10 illustrates the E-NB according to the second variant of implementation of the present invention.

Referring to Figure 10, at step 1001 E-NB detects that the time has come to pass the information cycle (timer) re-transmitting the SR/BSR according to the priorities through the system information, or finds the need to transfer information through the service signals according to the UE. At step 1011 E-NB specifies the information cycle (timer) re-transmitting the SR/BSR according to the priorities by reviewing information such as the status radioresource (for example, the state of the load cell) and the SR/BSR received from UE, the cell. At step 1021 E-NB transmits the information cycle (timer) re-transmitting the SR/BSR according to the priorities in the UE through system information or a service signals according to the UE.

11 illustrates a structure of a UE according to the second variant of implementation of the present invention.

Referring to 11, the UE includes the top level 1101, block 1111 buffer Manager data service signals unit 1121 of the transceiver and the timer 1131.

The upper level 1101 includes an upper control unit for generating control signals and the upper application block for data generation. Data or control signals generated at the top level 1101, transmitted in the transmission buffer (not shown). If the transmit buffer is filled with data or control signals transmitted from the upper level 1101, block 1111 buffer Manager data service signals transmits the SR/BSR in the E-NB through block 1121 transceiver to request E-NB to allocate radioresource for transmission on the uplink communication. Using the information cycle (timer) re-transmission according to the priorities that have already requested through the service signals according to the UE, the timer 1131 starts the cycle (timer) retransmission corresponding to the highest priority included in the SR/BSR, transmitted by UE. According to the signal of channel resources, adopted in which the PTO in downlink through block 1121 transceiver after the transmission of the SR/BSR, The UE determines the selection radioresource for transmission on the uplink by the UE. If radioresource for transmission on the uplink by the UE is allocated, the UE transmits data or control signals in the transmit buffer through the block 1121 transceiver through the use of dedicated radioresource. However, if radioresource for transmission on the uplink by the UE is not allocated, the UE determines the expired if the previously running cycle (timer). If the cycle (timer) has expired, the UE re-transmits the SR/BSR through the block 1121 transceiver and starts the cycle (timer)corresponding to the highest priority included in the retransmitted SR/BSR.

Fig illustrates the structure of the E-NB according to the second variant of implementation of the present invention.

Referring to Fig, E-NB includes block 1201 job cycle/timer priorities, block 1211 transceiver and the timer 1221.

Block 1201 job cycle/timer sets priorities cycles (timers) re-transmitting the SR/BSR according to the priorities. I.e. block 1201 job cycle/timer priorities sets the corresponding cycle (timer) re-transmission on the basis of priorities by reviewing information such as the status radioresource (for example, the state of the load cell) and the SR/BSR received from the UE in the cell. Unit 1211 transceiver of the E-NB lane who gives a specified cycle (timer) retransmission according to each priority in the corresponding UE through system information or a service signals according to the UE. If the cycle (timer) retransmission specified on the basis of the priorities is transmitted through system information, system information can be cyclically transmitted according to the timer settings 1221.

The above-described first and second embodiments of the present invention can be carried out simultaneously and not separately. For example, retransmission of the SR/BSR can repeatedly and cyclically performed according to the cycles of re-transmission in accordance with the priorities through the application of a first variant implementation of the present invention, when the highest priority is transmitted in the E-NB by UE, is less than the minimum priority of the received E-NB, and the simultaneous application of the first and second embodiments of the present invention, when the highest priority equal to or greater than the minimum allowed priority.
