1. A method for communication in a wireless system, comprising:
receiving, at a base station: (1) a capability report for each of a plurality of antenna panels of a user device; and (2) an initial antenna panel index for the user device;
transmitting, from the base station, to the user device, configuration information corresponding to each antenna panel of the plurality of antenna panels of the user device;
selecting, at the base station, first configuration information corresponding to a first antenna panel of the user device with the initial antenna panel index; and
receiving, at the base station, a first uplink (UL) transmission from the user device, wherein the UL transmission is transmitted using the first antenna panel corresponding to the initial antenna panel index and the first configuration information, and
receiving, at the base station, a power headroom report (PHR) from the user device, wherein the PHR corresponds to a second antenna panel, wherein a gap between a maximum transmission power of the second antenna panel and the first antenna panel is larger than a threshold.
