Device.
Background technology
In existing Long Term Evolution (Long Term Evolution, abbreviation LTE) communication system, Yi Jigao
In level Long Term Evolution (LTE-Advanced, abbreviation LTE-A) communication system, user equipment (User
Equipment, abbreviation UE) data that is sent to base station is by Physical Uplink Shared Channel (Physical
Uplink Shared Channel, abbreviation PUSCH) transmit.The ascending resource that PUSCH uses is by BS
Distribute to UE.In order to reduce the waste of ascending wireless resource as far as possible, UE needs by sending logic channel group
Buffer Status Report (Buffer Status Report, abbreviation BSR) give base station so that base station is known
UE needs the size of data by PUSCH transmission, and then can make rational decision-making, to UE's
PUSCH distributes suitable ascending wireless resource.
In prior art, the BSR that UE reports base station is in media access control layer (Medium Access
Control, abbreviation MAC) protocol Data Unit (Protocol Data Unit, abbreviation PDU) insert
Bit information, each MAC PDU at most inserts the MAC control element (Control of a BSR
