Description
Technical field
The present invention relates to the digital mobile communication technical field, relate in particular to a kind of management method of status report retransmission timer in buffer zone.
Background technology
Long Term Evolution (LTE, Long Term Evolution) universal land radio access web (E-UTRAN of evolution in system, Evolved Universal Terrestrial Radio Access Network) Radio interface protocols uplink layer 2 structures as shown in Figure 1, this Radio interface protocols uplink layer 2 is comprised of a plurality of base stations (eNB), wherein, media access control (MAC, Media Access Control) protocol layer comprises scheduling/processed (Scheduling/Priority handling) functional entity and mixed automatic retransfer (HARQ) functional entity, eNB realizes uplink scheduling function and processed function by Scheduling/Priority handling functional entity, and the realization of this uplink scheduling function and processed function also needs subscriber equipment (UE, what User Equipment) report comprises each logic channel group (LCG, logical Channel Group) Buffer Status Report of data cached situation (BSR, Buffer Status Reporting).
Different according to trigger condition, BSR is divided into three kinds: conventional Buffer Status Report (Regular BSR), filling Buffer Status Report (Padding BSR) and periodic buffer status report (Periodic BSR).
Wherein, the trigger condition of Regular BSR comprises: the Serving cell that new data waiting for transmission arrives empty buffering area, arrive buffering area, UE from the upper strata data to be transmitted of high priority logic channel changes, BSR retransmission timer (RETX_BSR_TIMER) is overtime and buffering area has data waiting for transmission;
Here, described RETX_BSR_TIMER is used for solving in the BSR transmitting procedure, if BSR loses, the mixed automatic retransfer functional entity can retransmit this BSR, and like this, BSR is not just to arrive according to the order of sequence eNB, make eNB because judging which BSR is up-to-date, be not used for sending Uplink Shared Channel (UL-SCH, the Upiink Shared Channel) resource of BSR and do not distribute to UE, and then cause UE because obtaining for a long time the problem that the UL-SCH resource can not send this BSR; At present the processing procedure of RETX_BSR_TIMER comprised: when sending BSR, start RETX_BSR_TIMER; After unlatching, all restart RETX_BSR_TIMER when receiving uplink authorization (UL Grant) or when again sending BSR, overtime and buffering area has data to be transmitted just to trigger Regular BSR as RETX_BSR_TIMER.
The trigger condition of Padding BSR comprises: UE has obtained ascending resource, in this ascending resource, filling bit is controlled (the MAC CE of unit more than or equal to the BSR key-course, MAC Control Element) size, and buffering area is both to be sent without Regular BSR, and is also to be sent without Periodic BSR.
The trigger condition of Periodic BSR comprises: (PERIODIC BSR TIMER) is overtime for the BSR cycle timer.
Regular BSR can trigger dispatch request (SR, Scheduling Request).SR is used for asking to distribute the UL-SCH resource to UE to eNB, the upper transmission of the capable physically control channel (PUCCH, Physical UplinkControl Channel) of SR, and eNB distributes the PUCCH resource for UE in advance.
After Regular BSR triggers SR, by this SR being processed ask eNB to distribute the flow process of UL-SCH resource as follows:
Step 1, at a transmission intercal (TTI), Regular BSR has triggered a SR, and UE is at the SR that processes, execution in step 2 begins to process this SR; If have, this SR is not processed, namely this SR is in suspension status, until when processing the flow process of described SR processing and finishing, cancel this SR;
Step 2, this SR is labeled as SR1, the SR counter is clear 0, judges whether UE has the PUCCH resource, if having, and execution in step 3; Otherwise, execution in step 9;
Step 3, transmission SR, the SR counter adds 1, execution in step 9;
Step 4, in current TTI, determine whether to receive UL Grant, if receive, execution in step 5; If confiscate, execution in step 6;
Step 5, cancel all SR, finish this handling process;
Wherein, the SR that all SR comprise the handled SR of this handling process and RegularBSR triggers in this handling process, the described SR that Regular BSR triggers in this handling process is the SR that is in suspension status;
Step 6, judge whether UE has the PUCCH resource, if having, execution in step 7; If no, execution in step 9;
Step 7, judge the maximum transmission times of the SR whether current value of counter equals to set in advance, if equal, discharge the PUCCH resource, execution in step 8; Otherwise, return to step 3;
Step 8, cancel all SR, finish this handling process, UE enters random access procedure;
Step 9, current TTI finish, and when entering next TTI, think that this next one TTI is current TTI, return to step 4.
By above-mentioned flow process as seen, the SR that triggers in a SR handling process all is in suspension status, on the not impact of this time SR handling process, that is, distributes the UL-SCH resource there is no help to request to UE, is unnecessary SR.But overtime in the handling process of certain SR as RETX_BSR_TIMER, and then when triggering SR, namely produced described unnecessary SR.
