Title:
FEEDBACK INFORMATION TRANSMISSION METHOD AND DEVICE, USER EQUIPMENT, AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2021/007783
Kind Code:
A1
Abstract:
The present disclosure relates to a feedback information transmission method and device, user equipment, a base station, and a computer-readable storage medium. The feedback information transmission method comprises: after a preset duration of transmission conflicts between feedback information of first service data and second service data, receiving first downlink control information (DCI) sent by a base station, wherein the priority of a first service is lower than that of a second service; obtaining, from the first DCI, a transmission resource for retransmitting the feedback information of the first service data; and retransmitting the feedback information of the first service data using the transmission resource. Embodiments of the disclosure resolve the issue regarding how to retransmit, in a scenario of mixed transmissions of first service data and second service data, feedback information of the first service data after the feedback information has been punctured or discarded, thereby preventing the base station from performing unnecessary first service retransmissions over PDSCH.
