Title:
CHANNEL FEEDBACK METHOD, TERMINAL DEVICE AND NETWORK DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/056725
Kind Code:
A1
Abstract:
The present application provides a channel feedback method, a terminal device and a network device, capable of avoiding the problem of disorder when receiving downlink data under the condition that the value of a feedback time sequence corresponding to a downlink channel is an invalid value. The channel feedback method comprises: the terminal device receives configuration information which is used to configure the terminal device to receive a second downlink channel after a first downlink channel, wherein the value of a feedback time sequence corresponding to the first downlink channel is an invalid value, feedback information corresponding to the second downlink channel is transmitted through a first uplink channel, and resources of the first uplink channel are configured by high-level signaling; and under the condition that target downlink control information is not received before a first time, the terminal device clears feedback information corresponding to the first downlink channel, or the terminal device does not demodulate the second downlink channel, wherein the target downlink control information is used to instruct the terminal device to send the feedback information corresponding to the first downlink channel before or during a time unit where the first uplink channel is located.
