Abstract:
A method of beam failure recovery request (BFRQ) transmission is proposed. UE can search for UE-specific control channel in a search space that is signaled specifically for monitoring network response of the BFRQ. Furthermore, configurations indicated specifically for BFRQ can be carried by dedicated signaling such as high-layer radio resource control (RRC) signaling. After successfully rebuilding connection, UE assumes the demodulation reference signal (DMRS) ports of UE-specific control channel to be spatially quasi-co-located (QCL-ed) with the reference signals identified during the beam failure recovery procedure.
