Abstract
Embodiments of an uplink timing adjustment method and a terminal are disclosed. The method includes: when a Time Alignment Timer TAT corresponding to a first Timing Advance adjustment Group TAG fails, requesting, by a terminal, a serving cell corresponding to a second TAG to coordinate uplink timing of a serving cell corresponding to the first TAG; receiving, by the terminal, a Timing Advance Command TAC corresponding to the first TAG; and adjusting, by the terminal, the uplink timing of the serving cell corresponding to the failed first TAG according to the TAC corresponding to the first TAG.
Claims14
An uplink timing adjustment method, comprising:
- when a Time Alignment Timer TAT corresponding to a first Timing Advance adjustment Group TAG fails, requesting, by a terminal, a serving cell corresponding to a second TAG to coordinate uplink timing of a serving cell corresponding to the first TAG;
- receiving, by the terminal, a Timing Advance Command TAC corresponding to the first TAG;
- and
- adjusting, by the terminal, the uplink timing of the serving cell corresponding to the failed first TAG according to an uplink timing adjustment amount in the TAC corresponding to the first TAG.
A terminal, comprising:
- a processor and a transceiver and a memory, wherein the processor is communicatively coupled to the memory and the transceiver, the memory stores program codes and data, and the processor is configured to call the program codes and the data in the memory to perform:
- when a Time Alignment Timer TAT corresponding to a first Timing Advance adjustment Group TAG fails, request a serving cell corresponding to a second TAG to coordinate uplink timing of a serving cell corresponding to the first TAG;
- receive by the transceiver a Timing Advance Command TAC corresponding to the first TAG;
- and adjust the uplink timing of the serving cell corresponding to the failed first TAG according to an uplink timing adjustment amount in the TAC corresponding to the first TAG.
