Abstract:
A user equipment (UE) is configured to establish a connection to a base station, wherein the base station configures the UE with a first beam corresponding to a first transmission reception point (TRP) and a second beam corresponding to a second TRP, wherein the first and second beam are in frequency range 2 (FR2) and wherein the UE does not support simultaneous reception of multiple beams in FR2, detect a beam failure during a beam failure detection (BFD) evaluation period, identify one or more candidate beams during a candidate beam detection (CBD) evaluation period and transmit a beam failure recovery (BFR) request to the base station.
