Title:
FEEDBACK INFORMATION PROCESSING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/008434
Kind Code:
A1
Abstract:
Disclosed are a feedback information processing method and device. In the feedback information processing method, a terminal at least calculates feedback information on the basis of a PDSCH retransmitted by a first transmission time unit; and sending the feedback information on a first feedback time unit. The first transmission time unit is the last transmission time unit, for retransmitting the PDSCH, in a feedback window of the first feedback time unit. Therefore, the terminal sends the feedback information of the PDSCH on at least two feedback time units, such that the reliability of the feedback information can be ensured. In addition, the first feedback time unit is not the last one from among a plurality of feedback time units, such that a delay resulting from the terminal only being able to send the feedback information of the PDSCH on the last feedback time unit is avoided, namely, fast feedback can be realized. The technical solution provided in the present application is applicable to HARQ-ACK information feedback corresponding to a semi-static HARQ-ACK codebook and a dynamic HARQ-ACK codebook.
