1. One or more non-transitory computer-readable media comprising compute device-executable instructions, wherein the instructions, in response to execution by a user equipment (“
- UE”
), cause the UE to;
generate a media access control (“
MAC”
) control element associated with power headroom (“
PHR”
) information for dual connectivity, wherein the MAC control element includes;
one or more first octets associated with a master cell group, the one or more first octets to include a PHR value associated with a first wireless primary cell (“
PCell”
) of the master cell group; and
one or more second octets associated with a secondary cell group, the one or more second octets to include a PHR value associated with a second wireless PCell of the secondary cell group; and
cause transmitter circuitry of the UE to transmit the MAC control element to one or more evolved Node Bs.

Abstract
Embodiments described herein relate generally to a communication between a user equipment (“UE”) and a plurality of evolved Node Bs (“eNBs”). A UE may be adapted to operate in a dual connected mode on respective wireless cells provided by first and second eNBs. The UE may be adapted to estimate respective power headroom (“PHR”) values associated with simultaneous operation on the first and second wireless cells. The UE may cause the first and second PHR estimates to be transmitted to both the first and second eNBs. The first and second eNBs may use these estimates to compute respective uplink transmission powers for the UE. Other embodiments may be described and/or claimed.
