1. An apparatus to be included in a user equipment (“
- UE”
), the apparatus comprising;
transmitter circuitry; and
processor circuitry coupled to the transmitter circuitry, the processor circuitry to simultaneously operate on a first wireless primary cell (“
PCell”
), provided by a first eNB (evolved Node B), and a second wireless PCell, provided by a second eNB, and to compute a first estimate of a power headroom (“
PHR”
) associated with the first wireless PCell and a second estimate of a PHR associated with the second wireless PCell;
the processor circuitry to identify an uplink transmission power based on the first estimate and the second estimate in response to transmission of the first estimate and the second estimate;
the processor circuitry to cause the transmitter circuitry to transmit an uplink communication based on said uplink transmission power in response to receipt of an indication of said uplink transmission power.

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.
