Abstract

Apparatuses, systems, and methods for beam failure recovery based on a unified TCI framework. A UE may receive, from a base station, a configuration for a BFR procedure for a CCG. The CCG may include at least two CCs and the UE may periodically receive, from the base station, at least a first BFD RS and a first CBD RS in a first CC included in the CCG. The UE may detect, based on the first BFD RS, a beam failure in at least the first CC and send, to the base station, a BFRQ. The BFRQ may include a candidate beam selected based on at least the first CBD RS and may be sent via a PRACH or MAC CE. The UE may receive, from the base station, a BFR response and apply the candidate beam to the first CC and at least one additional CC of the CCG.
