Abstract

Embodiments of the present invention provide a method for uplink transmission, a base station and user equipment. The method includes: receiving uplink offload information sent by the first base station, the uplink offload information is used to instruct the second base station to receive data in the cache corresponding to N1 logical channel groups of the user equipment, wherein the N1 logical channel groups are provided by the first The base station determines from the buffer status report BSR sent by the UE, and N1 is a positive integer greater than 0; determines N2 logical channel groups from N1 logical channel groups, and N2 is a non-negative integer less than or equal to N1; sends to the first base station Feedback information, where the feedback information is used to indicate the above determination result. In the embodiment of the present invention, during uplink transmission, the macro base station and the micro base station coordinate to determine the distribution mode of uplink data, which improves the flexibility of uplink transmission.

Description

technical field [0001] Embodiments of the present invention relate to the field of wireless communication, and more specifically, relate to an uplink transmission method, a base station, and user equipment. Background technique [0002] In the Long Term Evolution-Advanced (LTE-A) system, the shared channel is used to transmit data, and the user equipment (User Equipment, UE) and the evolved base station (evolved Node B, eNB) establish a radio bearer (Radio Barrier, RB) After that, there is no fixed data uplink resource. When the UE has uplink data to send, it requests uplink resources from the eNB. After the eNB allocates uplink resources, the UE uses the uplink resources to send uplink data. [0003] The UE may request uplink resources from the eNB in ​​a buffer status report (Buffer Status Report, BSR) manner. BSR is a more detailed notification method, which not only notifies the eNB that the UE has data to be uploaded, but also notifies the eNB of the amount of data t...
