1. An apparatus for a user equipment (UE), the apparatus comprising:
a memory to store multiple power headroom (PHR) values for dual connectivity; and
one or more processors to:
generate a media access control (MAC) control element associated with the multiple power headroom (PHR) values for dual connectivity, wherein the MAC control element includes:
a first indication associated with a master cell group, the first indication corresponding to a first PHR value associated with a first wireless primary cell (PCell) of the master cell group; and
a second indication associated with a secondary cell group, the second indication corresponding to a second PHR value associated with a second wireless PCell of the secondary cell group; and
instruct the UE to transmit the MAC control element to one or more base stations.
