Claim of US Patent No. 10,993,192

1. A method for a user equipment (UE), the method comprising:using multiple beams for transmission;
triggering, by the UE, a power headroom report due to a change of a pathloss being larger than a threshold, wherein the pathloss is associated with a specific beam, wherein the pathloss is derived from a synchronization signal, and wherein a UE transmission power for an uplink (UL) transmission by the UE is controlled per a set of the multiple beams; and
determining, by the UE, whether the pathloss has changed if a transmission associated with the specific beam is scheduled.
