1. A method for frequency range two (FR2) beam management, comprising:
configuring, via communications with a base station, a group identifier (ID) for physical uplink control channel (PUCCH) resources within a group of PUCCHs;
updating, based on a medium access control (MAC) control element (CE) received from the base station, one or more PUCCH resources within the group of PUCCHs, wherein the MAC CE includes one of a resource ID or the group ID;
receiving, from the base station, an update to a pathloss measurement reference signal (RS); and
continuing, when the updated pathloss measurement RS cannot be measured at least once prior to transmission of a subsequent signal, to use a pathloss estimate from a prior RS to determine an uplink open loop transmit power until a pathloss can be measured from the updated pathloss measurement RS.
