Title:
FEEDBACK INFORMATION SENDING AND RECEIVING METHOD AND DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/215222
Kind Code:
A1
Abstract:
The present disclosure relates to a feedback information sending and receiving method and device, and a medium, wherein the sending method is applied to a first transmission device of two transmission devices, comprising: configuring a base sequence to generate N cyclic shift sequences, wherein, N is an integer greater than 1; and sending the N cyclic shift sequences to a second device. The receiving method is applied to a second transmission device of two transmission devices, comprising: receiving the N cyclic shift sequences sent by the first device; determining N cyclic shift configuration values of the N cyclic shift sequences; and determining feedback information returned by the first device according to the N cyclic shift configuration values. The present disclosure can eliminate the influence of signal delay on cyclic shift detection, and effectively improve the reliability and transmission efficiency of a feedback channel.
