Abstract

The embodiment of the invention provides a method and apparatus for determining beam failure detection reference signal BFD RS resources. The method is applied to user side equipment, and comprises the following steps: when BFD RS resources used for performing beam failure detection reference signal BFD RS measurement are not configured, determining the BFD RS resources according to a transmissionconfiguration indication (TCI) state of a control resource set CORESET. According to the embodiments of the present invention, when the user side device is not configured with the BFD RS resource forperforming the BFD RS measurement, the BFD RS resource can be determined according to the TCI state of the CORESET, thereby facilitating the user side device to perform the beam failure detection andthe beam failure recovery.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and equipment for determining BFD RS resources of beam failure detection reference signals. Background technique [0002] In high-frequency communication systems, due to the short wavelength of wireless signals, signal propagation is more likely to be blocked, resulting in interruption of signal propagation. Therefore, a beam failure recovery mechanism is currently introduced into the beamforming beam measurement mechanism. In the beam failure recovery mechanism, the network side equipment configures beam failure detection reference signal (beam failure detection reference signal, BFD RS) resources for the user equipment (user equipment, UE), and the UE measures the BFD RS according to the configured BFDRS resources, and After it is determined that the beam failure event occurs, a beam failure recovery request is reported to the network side device, so as to facilitate ...
