Abstract

The invention provides a method and a device for determining beam failure detection (BFD) resource, communication equipment and a medium, and belongs to the technical field of wireless communication. The method comprises: a terminal device determines configuration information sent by a network device, and determines a target transmit-receive point (TRP) and a target BFD resource corresponding to the target TRP according to the configuration information, so that the terminal device can detect whether a beam failure occurs in the target TRP based on the target BFD resource. Therefore, the terminal device can detect the beam failure of the target TRP in time based on the BFD resource so as to recover the beam failure as soon as possible, thereby ensuring the communication efficiency and communication reliability between the terminal device and the network device.

Description

technical field [0001] The present disclosure relates to the field of wireless communication technologies, and in particular to a method, device and communication equipment for determining BFD resources for beam failure detection. Background technique [0002] In NR (New Radio, new wireless technology or new air interface), especially when the communication frequency band is in the frequency range (frequency range) 2, because the high-frequency channel attenuates quickly, in order to ensure the coverage of the signal, you can use beam ( Beam) transmission and reception. Generally, the better the alignment between the beam and the communication equipment, the greater the signal gain provided by the beam. However, due to the influence of factors such as sudden fluctuations, faults or interruptions of the channel, and the occlusion of buildings, beam failures sometimes occur. When a beam failure occurs, the communication device needs to switch the current failed beam to other ...
