Abstract

The present application discloses a beam failure reporting information indication method based on data scheduling, which is used for terminal equipment, including the following steps: reporting failed carrier information, wherein the number of reported identified carriers does not exceed the third threshold, according to the first signal quality parameter A threshold, detecting carrier beams, determining failed beams or candidate beams; reporting failed beams or candidate beam information, wherein the number of reported failed beams or candidate beams does not exceed the second threshold. Solve the problem of large amount of data in the signaling process when the beam fails.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a beam failure reporting information indication method for a new air interface. Background technique [0002] In high-band millimeter-wave communication, the angle coverage of the control channel is limited, which may easily cause holes in the coverage of the control channel, unable to ensure reliable reception of the control channel, and beam failure. Therefore, NR introduces a fast and reliable beam failure detection and recovery process, enabling network devices to quickly resume transmission from beam failure. The main process is as follows: the quality of each downlink control channel beam received by the terminal is lower than a specified threshold, so that the terminal equipment cannot effectively receive the control information sent by the PDCCH. Assuming that the network device has M beams for downlink control channel transmission, a dedicated...
