Abstract

The invention discloses a method for processing a cache state report and a scheduling request and user equipment. The method comprises the steps of receiving a contention-based transmission scheduling command transmitted by a base station by UE (User Equipment); transmitting a contention-based transmission to the base station according to the received transmission scheduling command, wherein the contention-based transmission comprises BSR (Buffer State Report) of the UE or all uplink data to be transmitted; and after receiving contention success identifier information transmitted by the base station, cancelling the BSR and/or SR having been triggered while the contention-based transmission is transmitted. By using a technical scheme of the invention, the problem that the uplink data of the UE cannot possibly be scheduled in time because the triggered BSR and SR are cancelled after the UE finishes the transmission of the contention-based transmission in the prior art is solved.

Description

The processing method of buffer status report and dispatch request and subscriber equipment

Technical field

The present invention relates to communication technical field, particularly the processing method of a kind of buffer status report and dispatch request and subscriber equipment.

Background technology

Long Term Evolution (LTE, Long Term Evolution) LTE (LTE-A of system and evolution, LTE-Advanced) system is all the communication system based on scheduling of resource, subscriber equipment (UE, UserEquipment) by buffer status report (BSR, Buffer State Report) to base station, report the data volume of the medium upstream data to be sent of buffer memory of this UE, the data volume of the upstream data that base station need to send according to this UE, for UE divides the uplink transmission resource that is used in carrying upstream data, wherein, according to UE, trigger the triggering mode that BSR reports, BSR is divided into three types, be specially:

The first type, conventional BSR (Regular BSR): arrive if UE detects the data higher than the priority of the data of current storage in buffer memory, trigger reporting of Regular BSR, if UE has detected data and has arrived while there is no data in script buffer memory, trigger reporting of Regular BSR, if Retx_BSR_Timer is overtime and buffer memory in store data, trigger reporting of Regular BSR;

The second type, periodically BSR (Periodic BSR): if Periodic_BSR_Timer is overtime, trigger reporting of Periodic BSR;

The third type, incidentally BSR (Padding BSR): if UE is when needs send MAC PDU, in uplink transmission resource, except the upstream data that carrying needs to send, also have available uplink transmission resource, trigger Padding BSR.

Base station is distributed to uplink transmission resource after UE, if UE just can all be carried on all upstream datas that send that need in the uplink transmission resource of distribution, UE no longer reports BSR to base station, but directly send upstream data, if UE can not all be carried on all upstream datas that send that need in the uplink transmission resource of distribution, UE reports BSR to base station, the BSR that base station reports according to UE, determine the data volume of the upstream data that this UE need to send, and then according to the data volume of determining, carry out the scheduling of uplink transmission resource, if there is multiple BSR to trigger simultaneously, UE only reports the BSR that priority is the highest.

If UE has triggered reporting of conventional BSR, and there is no an available uplink transmission resource, this UE triggers dispatch request (SR, Scheduling Request), to base station, send SR, request base station distributes uplink transmission resource to this UE, and as shown in Figure 1, the detailed process that UE sends upstream data according to the uplink transmission resource of base station assigns is as follows:

Step 11, UE sends SR to base station;

Step 12, base station assigns is for transmitting the uplink transmission resource of BSR;

Step 13, the uplink transmission resource that UE distributes in step 12 according to this base station, reports current BSR to this base station;

Step 14, base station is according to the BSR receiving, for UE divides the uplink transmission resource that is used in transmit ascending data;

Step 15, UE is according to the uplink transmission resource of base station assigns, and the upstream data that need to be transferred to base station sends to this base station.

If UE has comprised up-to-date BSR or whole upstream data in uplink, cancel BSR and the SR having triggered.In the Rel-9 stage, also introduced dispatch request and forbidden timer SR-ProhibitTimer.In version before Rel-9, SR is once triggering, will be at follow-up all Physical Uplink Control Channel (PUCCH that can send special-purpose SR (D-SR), Physical Uplink Control Channel) in resource, send, introducing SR-ProhibitTimer is in order to limit the time interval of twice SR transmission.SR-ProhibitTimer starts or restarts when D-SR sends, and SR-ProhibitTimer is overtime just can send D-SR next time afterwards, and SR cancels needs to stop SR-ProhibitTimer simultaneously.

Based on competition (CB, Contention Based) uplink refers to that base station is carried at the uplink transmission resource distribution based on competition in the transmitting and scheduling order based on competition and sends to UE, UE sends upstream data according to the uplink transmission resource based on competition of base station assigns, as shown in Figure 2, its concrete processing procedure is as follows:

Step 21, base station sends to UE by the uplink configuration information based on competition, and this uplink configuration information comprises the transmitting and scheduling identification information based on competition etc.;

Step 22, this UE receives and stores above-mentioned uplink configuration information;

Step 23, base station sends the transmitting and scheduling order based on competition to this UE;

Step 24, this UE, according to the transmitting and scheduling order receiving, sends the transmission based on competition to base station;

Step 25, base station after receiving the transmission based on competition that UE sends, solutions that be at war with, and the competition results that comprises competition and solve sign is fed back to and competes successful UE.

In prior art, when base station is that UE has distributed uplink transmission resource, and the uplink transmission resource of this UE based on distributing sends after upstream data to base station, this UE will cancel BSR and the SR of triggering, if the competition results of the transmission of the carrying out of this UE based on competition is for to compete unsuccessfully, and now this UE can not send BSR and SR again to base station, non-competing uplink transmission resource just can not be distributed for this UE in base station, this has just caused the upstream data of this UE to be dispatched in time, can not send to base station, overlong time can cause the loss of UE storage data.
