Description
Technical field
The present invention relates to the digital mobile communication technical field, relate in particular in the wireless communication system processing method of periodic buffer status report timer and terminal in the Buffer Status Report flow process.
Background technology
Long Term Evolution (Long Term Evolution at 3G (Third Generation) Moblie, abbreviating LTE as) in the system, up medium access control (Media Access Control abbreviates MAC as) scheduler is positioned at base station (eNodeB, abbreviate eNB as), be the terminal distribution transfer resource.Before being the terminal distribution transfer resource, up MAC scheduler need be known the state information of the current buffering area of terminal (User Equipment abbreviates UE as).
At present, up MAC scheduler mainly is Buffer Status Report (the Buffer State Report by terminal to report, abbreviate BSR as) know the state information of the current buffering area of UE, such as, whether data, data what and data type etc. are arranged in the UE buffering area.
According to the type that BSR triggers, BSR can be divided into regular BSR (RegularBSR), fill BSR (Padding BSR) and periodicity BSR (Periodic BSR).In addition, according to data cached logic channel group number, Regular BSR, Periodic BSR and Padding BSR can be divided into two types again: short BSR (short BSR) and long BSR (long BSR).
For Regular BSR and Periodic BSR, if current Transmission Time Interval (Transmission Time Interval, abbreviate TTI as) only there are the data of a logic channel group to transmit, then this BSR is short BSR, if this TTI has the data of an above logic channel group to transmit, then this BSR is long BSR.
For Padding BSR, if the filler of BSR is equal to or greater than the short BSR that adds the son head, but less than the long BSR that adds the son head, two kinds of dispositions are arranged: if an above logic channel group has data cached, but transmit the highest priority logical channel transmitting data information of BSR, then this BSR is called brachymemma BSR (Truncated BSR); If there only have a logic channel group to have to be data cached, this BSR is called short BSR.If the filler of BSR is equal to or greater than the long BSR that adds the son head, this BSR reports the BSR into long.
Wherein, Regular BSR can trigger under following several situations: when (1) new data arrives empty buffering area; When (2) high preferential data arrive the buffering area of existing low prioritized data existence; When (3) Serving cell changes; (4) retransmit when having available data to transmit among the overtime and UE of BSR timer (RETX_BSR_TIMER).And Periodic BSR only may trigger in one case, and promptly periodically BSR timer (Periodic BSR Timer) is overtime.And Padding BSR has distributed at ascending resource, and the quantity of filler is equal to or greater than under the situation of size of control element (BSRMAC Control Element abbreviates BSR MAC CE as) of BSR media access control layer and triggers.
The schematic flow sheet that Fig. 1 reports for BSR in the prior art, as shown in Figure 1, whether UE is main according to having new transmitted up (Up Load abbreviates UL as) to authorize (Grant) (being also referred to as ascending resource) to determine whether to report BSR in the prior art, and it mainly comprises following processing:
(1) if do not have new transmitted UL Grant in current TTI, but Regular BSR triggers, and then UE sends dispatch request (SR) to eNodeB, triggers the dispatch request flow process.
(2) if new transmitted UL Grant is arranged at this TTI, and send from last BSR that at least one BSR of back is triggered always or at least one BSR triggers for the first time, then indicate multiplexing and assembling flow path generation BSR MAC CE, if and this BSR is not TruncatedBSR, start or restart Periodic BSR Timer, start then or restart RETX_BSR_TIMER.
(3) continuous BSR flow process is during the stage, if a plurality of BSR are triggered, can only send a BSR, and this BSR is included in Medium Access Control (MAC) Protocol Data Unit (MAC ProtocolData Unit, abbreviate MAC PDU as) middle transmission, wherein, Regular BSR and Periodic BSR priority are higher than Padding BSR, promptly when Regular BSR, PeriodicBSR and Padding BSR trigger simultaneously, preferentially carry out Regular BSR or PeriodicBSR.
In above-mentioned BSR flow process, in service as RETX_BSR_TIMER, be used for the Grant that Uplink Shared Channel (Up Link Shared Channel abbreviates UL-SCH as) new data transmits if receive, UE will be restarted RETX_BSR_TIMER.
Fig. 2 is for deleting the schematic diagram of the BSR that has been triggered in the present technology, as shown in Figure 2, the processing of the BSR that deletion has been triggered in the BSR flow process is divided into two kinds of situations.First kind of situation is: if when up grant can hold the capacity BSR MAC CE that all that can transmit hang data but can not be extra, all BSR that have been triggered are with deleted, as 1 place that is identified among Fig. 2.Second kind of situation is: transmit if there is a BSR to be comprised among the MAC PDU, all BSR that have been triggered are with deleted, as 2 places that identified among Fig. 2.
In the BSR flow process, in some cases, the buffering area of UE may not have the data that can send, and then may need to stop PERIODIC BSR TIMER, or do not start PERIODIC BSR TIMER, otherwise may cause the BSR of insignificant sky to report or unnecessary BSR triggering.
