Abstract
Provided are a communication method and a communication apparatus. The method includes: performing, by a terminal device, first Small Data Transmission (SDT) on a pre-Configured Grant (CG) resource corresponding to a first Synchronization Signal Black (SSB), wherein the terminal device is in an inactive state; and performing, by the terminal device, second SDT on the CG resource corresponding to the first SSB. According to the method in the embodiments of the disclosure, SDT of a User Equipment (UE) in an inactive state can be implemented.
Claims20
A communication method, comprising:
- performing, by a terminal device, first Small Data Transmission (SDT) on a Configured Grant (CG) resource corresponding to a first Synchronization Signal Black (SSB), wherein the terminal device is in an inactive state;
- determining, by a terminal device, a first resource in a condition where Timing Advance (TA) corresponding to the terminal device is valid, Reference Signal Receiving Power (RSRP) of the first SSB meets a preset threshold and there is the CG resource corresponding to the first SSB;
- or, determining the first resource in a condition where the TA corresponding to the terminal device is valid, the first SSB does not meet the preset threshold, RSRP of a second SSB meets the preset threshold and there is a CG resource corresponding to the second SSB, wherein the first SSB is one of a plurality of SSBs, and the second SSB is an SSB in the plurality of SSBs other than the first SSB;
- and
- performing, by a terminal device, second SDT on the first resource.
