Patent ID: 11445383

Abstract:
An information feedback method, device and system are provided. The method includes: determining, by a first communication node, feedback information for indicating a status of communication links between the first communication node and a serving communication node, where the feedback information includes at least one of the following: failure information of a first type of transmission link, a request for training signal of transmission modes and/or a request for training signal of receiving modes, and indication information of M preferred transmission links, and the first type of transmission link and the M preferred transmission links include transmission links from the serving communication node to the first communication node, where M is a positive integer greater than or equal to 1; and transmitting, by the first communication node, the feedback information to the serving communication node. The present disclosure solves the problem in the existing art of a low resource utilization rate because a receiving end and a transmitting end cannot learn a communication link failure in time, enables the receiving end and the transmitting end to learn a status of communication links between them in time, and effectively improves the resource utilization rate.
