Title:
PUSCH TRANSMISSION METHOD AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/155934
Kind Code:
A1
Abstract:
The present application provides a PUSCH transmission method and a communication apparatus. The method may comprise: receiving first indication information and second indication information from a network device, wherein the second indication information indicates a time domain unit offset, and the first indication information indicates that the repetition type of PUSCH transmission is a repetition type A and indicates a rated number K of repetitions; determining a starting time domain unit of a rated transmission PUSCH according to the time domain unit offset, wherein the previous time domain unit of the starting time domain unit is a first time domain unit, or K time domain units of the rated transmission PUSCH comprise the first time domain unit and the first time domain unit does not satisfy a configured length and starting position, and the first time domain unit comprises a downlink symbol and a non-downlink symbol; determining a PUSCH transmission symbol in the first time domain unit; and performing PUSCH transmission on the PUSCH transmission symbol. Thus, PUSCH transmission can be performed by means of the non-downlink symbol in the first time domain unit, thereby reducing waste of non-downlink symbol resources.
