Method and apparatus for reporting buffer status

摘要

A method and an apparatus for reporting buffer status are provided. The method includes: obtaining multiple Transport Blocks (TBs) from a base station within one Transmission Time Interval (TTI); selecting a TB compliant with a condition of transmitting a Buffer Status Report (BSR) among the multiple TBs; and bearing a BSR of a Logical Channel Group (LCG) and a Control Element (CE) sub-header of the BSR onto the selected TB and sending the TB to the base station. In this way, a UE can make full use of the padding bits of the obtained multiple TBs, and report the buffer status flexibly.

1. A method for reporting buffer status applied in carrier aggregation, comprising:
obtaining, by a user equipment (UE) configured with at least one logical channel group (LCG), a plurality of transport blocks (TBs) in a transmission time interval (TTI) from a base station; selecting, by the UE, from the plurality of TBs, a TB that meets a buffer status report (BSR) transmission condition, wherein in instances where, among the plurality of TBs obtained in the TTI, there is more than one TB meeting the BSR transmission condition, all the more than one TB meeting the BSR transmission condition are selected for BSR transmission; carrying onto each selected TB, by the UE, a BSR of an LCG and a control element (CE) sub-header corresponding to the BSR; and sending, by the UE, the BSR and the corresponding CE sub-header to the base station via each selected TB, wherein the at least one LCG of the UE includes a LCG which does not contain any logical channel, the method further comprises: processing, by the UE, the LCG which does not contain any logical channel by setting a buffer value of the BSR of the LCG which does not contain any logical channel to 0 or to a null value.
