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
Technical field
The present invention relates to communication technical field, the processing method and the subscriber equipment of particularly a kind of buffer status report and dispatch request.
Background technology
Long Term Evolution (LTE, Long Term Evolution) LTE (LTE-A of system and evolution, LTE-Advanced) system all is based on the communication system of scheduling of resource, subscriber equipment (UE, UserEquipment) by buffer status report (BSR, Buffer State Report) comes to report the data volume of the medium upstream data to be sent of the buffer memory of this UE to the base station, the base station is according to the data volume of the upstream data of this UE needs transmission, divide the uplink transmission resource that is used in the carrying upstream data for UE, wherein, trigger the triggering mode that BSR reports according to UE, BSR is divided into three types, is specially:
First type, conventional BSR (Regular BSR): if UE detects the higher data arrival of priority than the data of current storage in the buffer memory, then trigger reporting of Regular BSR, if UE has detected data and has arrived when not having data in the script buffer memory, then trigger reporting of Regular BSR, if store data in the overtime and buffer memory of Retx_BSR_Timer, then trigger reporting of Regular BSR;
Second type, periodicity BSR (Periodic BSR):, then trigger reporting of Periodic BSR if Periodic_BSR_Timer is overtime;
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, then trigger Padding BSR.
After UE is distributed to uplink transmission resource in the base station, if UE just can all be carried on all upstream datas that need send in the uplink transmission resource of distribution, then UE no longer reports BSR to the base station, but directly send upstream data, if UE can not all be carried on all upstream datas that need send in the uplink transmission resource of distribution, then UE reports BSR to the base station, the BSR that the base station reports according to UE, determine the data volume of the upstream data that this UE need send, and then carry out the scheduling of uplink transmission resource according to the data volume of determining, if there is multiple BSR to trigger simultaneously, then UE only reports the highest BSR of priority.
If UE has triggered reporting of conventional BSR, and there is not an available uplink transmission resource, then this UE triggers dispatch request (SR, Scheduling Request), promptly send SR to the base station, the request base station distributes uplink transmission resource for this UE, and as shown in Figure 1, UE is as follows according to the detailed process of the uplink transmission resource transmission upstream data of base station assigns:
Step 11, UE sends SR to the base station;
Step 12, base station assigns are used to transmit 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 are divided the uplink transmission resource that is used in transmit ascending data according to the BSR that receives for UE;
Step 15, UE is according to the uplink transmission resource of base station assigns, and the upstream data that needs is transferred to the base station sends to this base station.
If UE has comprised up-to-date BSR or whole upstream data in uplink, then cancel BSR and the SR that has triggered.In the Rel-9 stage, also introduced dispatch request and forbidden timer SR-ProhibitTimer.In the version before Rel-9, SR is once triggering, will follow-up all can send the Physical Uplink Control Channel (PUCCH of special-purpose SR (D-SR), Physical Uplink Control Channel) send on the resource, introducing SR-ProhibitTimer is in order to limit the time interval of twice SR transmission.SR-ProhibitTimer starts when D-SR sends or restarts, and just can send D-SR next time after SR-ProhibitTimer is overtime, and the SR cancellation need stop SR-ProhibitTimer simultaneously.
Based on competition (CB, Contention Based) uplink is meant that the base station will be carried at based on the uplink transmission resource distribution of competition based on sending to UE in the transmitting and scheduling order of competing, 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, the base station will send to UE based on the uplink configuration information of competition, comprise the transmitting and scheduling identification information etc. based on competition in this uplink configuration information;
Step 22, this UE receives and stores above-mentioned uplink configuration information;
Step 23, the base station sends based on the transmitting and scheduling order of competing to this UE;
Step 24, this UE sends based on the transmission of competing to the base station according to the transmitting and scheduling order that receives;
Step 25, base station after receiving the transmission that UE sends based on competition, solutions that be at war with, and will comprise competition result that competition solves sign and feed back to and compete successful UE.
In the prior art, when the base station is that UE has distributed uplink transmission resource, and this UE based on the uplink transmission resource of distributing after the base station sends upstream data, this UE will cancel the BSR and the SR of triggering, if the carrying out of this UE is the competition failure based on the competition result of the transmission of competition, and this moment, this UE can not send BSR and SR to the base station again, non-competing uplink transmission resource just can not be distributed for this UE in the base station, this has just caused the upstream data of this UE in time to be dispatched, can not send to the base station, overlong time can cause losing of UE storage data.
