Title:
BEAM FAILURE RECOVERY
Document Type and Number:
WIPO Patent Application WO/2020/010630
Kind Code:
A1
Abstract:
Embodiments of the present disclosure provide method, device and computer readable medium for beam failure recovery. In example embodiments, a method implemented at a terminal device is provided. The method comprises determining a configuration for receiving Physical Downlink Control Channels (PDCCHs) from a network device, the network device communicating with the terminal device via first and second Transmission and Reception Points (TRPs), wherein the configuration indicates which one of the first and second TRPs are the PDCCHs to be received from. The method further comprises determining whether a beam failure occurs in at least one of the first and second TRPs. In addition, the method further comprises, in response to determining that a beam failure occurs in at least one of the first and second TRPs, performing beam failure recovery (BFR) for the first and second TRPs at least based on the configuration.
