Title:
COMMUNICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/262531
Kind Code:
A1
Abstract:
A communication method and apparatus, which are used for determining how a terminal device monitors a PDCCH after DCI is received during a retransmission time period. The method comprises: a terminal device receiving first DCI from a network device, receiving second DCI from the network device in a second time domain length after receiving the first DCI, and determining, according to the second DCI, that the terminal device does not monitor a PDCCH in a third time domain length, wherein the first DCI indicates that the terminal device does not monitor a PDCCH in a first time domain length; the second time domain length belongs to the first time domain length; and the starting position of the third time domain length is the ending position of the second time domain length or is located after the second time domain length, and the ending position of the third time domain length is the ending position of the first time domain length. In this way, when a terminal device receives DCI during a retransmission time period, it is possible to keep the time for skipping a PDCCH, which is indicated by initially transmitted DCI, still valid.
