Title:

HARQ TRANSMISSION ENHANCEMENT METHOD, COMMUNICATION DEVICE, AND READABLE STORAGE MEDIUM

Document Type and Number:

WIPO Patent Application WO/2022/147660

Kind Code:

A1

Abstract:

Disclosed in the present application is an HARQ transmission enhancement method, comprising: receiving downlink transmission sent by a base station; when sending of an HARQ feedback signal for the downlink transmission is abnormal, determining whether the HARQ feedback signal satisfies a condition for postponing feedback; and if yes, selecting an uplink channel after an originally scheduled sending time unit of the HARQ feedback signal to transmit at least part of the HARQ feedback signal. Further disclosed in the present application are a communication device and a readable storage medium.
