POWER HEADROOM REPORTING WITH DUAL CONNECTIVITY

摘要

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.

1. A method to be performed by a user equipment (“UE”), the method comprising:
simultaneously operating on a first wireless primary cell (“PCell”), provided by a first eNB, and a second wireless PCell, provided by a second eNB; computing a first estimate of a power headroom (“PHR”) associated with the first wireless cell; computing a second estimate of a PHR associated with the second wireless cell; transmitting the first estimate; and transmitting the second estimate.
