1. A user equipment (UE), comprising:
one or more memories comprising executable instructions; and
one or more processors configured to execute the executable instructions and cause the UE to:
receive, from a network, a plurality of power control configurations, wherein:
each power control configuration of the plurality of power control configurations comprises a respective plurality of power control parameters;
each power control configuration of the plurality of power control configurations applies to a respective uplink channel or reference signal object associated with a common transmission configuration indication (TCI) state;
each respective power control configuration of the plurality of power control configurations depends on:
the respective uplink channel or reference signal object associated with that respective power control configuration; and
a respective common TCI state of a plurality of common TCI states associated with that respective power control configuration; and
at least one power control configuration of the plurality of power control configurations is configured implicitly based on:
a periodic uplink beam reference signal configured for the respective common TCI state associated with the at least one power control configuration; and
a radio resource control (RRC) flag in an RRC message received by the UE indicating a separate pathloss reference signal not being signaled by the network; and
transmit at least one uplink channel or reference signal object at a transmission power that is based on a measured path loss and at least one of the power control configurations of the plurality of power control configurations.
