Problems solved by technology

[0007] For a UE in the cross-site offload mode, since multiple sites provide uplink scheduling for the UE, the base station may send uplink scheduling resources, but the UE has no uplink data to send, resulting in a waste of scheduling resources

Abstract

Embodiments of the present invention provide a data transmission method, user equipment, and a base station. The method includes: the user equipment UE compares the data volume of the UE's cached data with a first cached data volume threshold value corresponding to the UE's cached data; if the data volume of the UE's cached data is smaller than the corresponding first cached data volume threshold value, the UE sends low buffered data amount indication information to the second base station, and the low buffered data amount indication information is used to instruct the second base station to stop providing uplink scheduling for the UE; wherein, the UE accepts the first The offload service of at least two base stations including the base station and the second base station. In the embodiment of the present invention, by comparing the data volume of the UE's cached data with the corresponding first cached data volume threshold value, and indicating when the data volume of the UE's cached data volume is less than the corresponding first cached data volume threshold value The second base station stops providing uplink scheduling for the UE, which improves utilization efficiency of scheduling resources.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and more specifically, relate to a data transmission method, user equipment, and a base station. Background technique [0002] Multiple logical channels of a user equipment (User Equipment, UE) are classified into different logical channel groups (Logical Channel Group, LCG), and each logical channel group has a different priority during scheduling by the base station. When the UE reports a buffer status report (Butter Status Report, BSR), it counts the amount of data to be sent for each logical channel group and reports them separately for the base station to make accurate scheduling decisions. If the UE does not trigger the BSR, but there are still some free radio resources after putting the data packets, and the data cannot be put, then the UE will send a truncated BSR or Padding BSR. If the UE has multiple logical channel groups with data to be sent at this time, the UE sends ...
