1. A user equipment device (UE), comprising:
at least one antenna;
at least one radio, wherein the at least one radio is configured to perform cellular communication using at least one radio access technology (RAT);
one or more processors coupled to the at least one radio, wherein the one or more processors and the at least one radio are configured to perform voice and/or data communications;
wherein the one or more processors are configured to cause the UE to:
receive, from a base station, a first uplink beam configuration for a group of component carriers;
communicate, with the base station, using the first uplink beam configuration for the group of component carriers; and
receive, from the base station, a second uplink beam configuration for the group of component carriers, wherein the second uplink beam configuration includes a medium access control (MAC) control element (CE) that updates a pathloss reference signal (PRS) for the group of component carriers.
