Title:

PDSCH TRANSMITTING METHOD AND APPARATUS, PDSCH RECEIVING METHOD AND APPARATUS, AND COMMUNICATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2022/222879

Kind Code:

A1

Abstract:

The present application relates to the technical field of communications, and discloses a physical downlink shared channel (PDSCH) transmitting method and apparatus, a PDSCH receiving method and apparatus, and a communication device. The PDSCH transmitting method of embodiments of the present application comprises: in the case that a second hybrid automatic retransmission request (HARQ) process corresponding to a second PDSCH scheduled by a network side device is the same as a first HARQ process corresponding to a first PDSCH, the network side device determines a first time, wherein the first PDSCH is a PDSCH scheduled by the network side device before scheduling the second PDSCH, the first time is related to first information, and the first information indicates whether a terminal feeds back hybrid automatic retransmission request acknowledgement (HARQ-ACK) of the first PDSCH; and the network side device sends the second PDSCH at a time not earlier than the first time.
