Title:
WIRELESS COMMUNICATION METHOD AND APPARATUS, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/205419
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a wireless communication method and apparatus, and a system. The method comprises: a terminal device receiving a PDSCH, wherein the PDSCH is scheduled by a PDCCH, and the PDCCH corresponds to two PDCCH candidates; and if a PUCCH carrying HARQ-ACK information of the PDSCH is not earlier than a first time point, the terminal device providing a piece of valid HARQ-ACK information, wherein the first time point is related to an overlapping symbol of the PDSCH and one PDCCH candidate in the two PDCCH candidates.
