Abstract

A beam detection method and device are used to solve the problem of lack of good communication quality for detecting downlink beams in the prior art. The beam detection method includes: the terminal equipment receives the beam quality monitoring signals sent by the network equipment using M beams; determining the signal quality indicators of the M beam quality monitoring signals, based on the signal of each beam quality monitoring signal in the M beam quality monitoring signals The quality index determines the beam quality index of the beam used to send the beam quality monitoring signal; generates the first detection report, including: the indication information of the beam whose beam quality index does not meet the first threshold among the M beams, at least one beam quality index At least one of the beam quality indicators of beams that do not meet the first threshold, the indication information of beams with at least one beam quality indicator that meets the second threshold, and the beam quality indicators of at least one beam quality indicator that meets the second threshold; to the network The device sends a first detection report.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a beam detection method and device. Background technique [0002] Beamforming technology is a multi-antenna transmission technology. By adjusting the weighting factor on each antenna unit, the width and direction of the beam can be flexibly adjusted to transmit wireless signals in a specific direction. [0003] The network device can perform beamforming on the downlink control channel (physical downlink control channel, PDCCH) to obtain the space diversity gain of the multi-antenna array. A possible beamforming method for the PDCCH is: the time available for PDCCH transmission / Frequency resources are divided into multiple components, and each component is called a control resource set (control resource set, CORESET). The network device can transmit downlink control information (downlink control information, DCI) on any CORESET through the downlink beam. ) of the ...
