Power sharing and power headroom reporting in dual connectivity scenarios
First Claim
1. A method for wireless communication by a user equipment (UE), comprising:
- determining a maximum available transmit power of the UE;
semi-statically configuring a first minimum guaranteed power available for uplink transmission to a first base station and a second minimum guaranteed power available for uplink transmission to a second base station; and
dynamically determining a first maximum transmit power available for uplink transmission to the first base station and a second maximum transmit power available for uplink transmission to the second base station based, at least in part, on the maximum available transmit power of the UE, the first minimum guaranteed power, and the second minimum guaranteed power, wherein dynamically determining the first maximum transmit power and the second maximum transmit power comprises;
determining an amount of the first minimum guaranteed power that is unused for uplink transmission to the first base station, andincluding at least a portion of the unused amount when determining the second maximum transmit power available for uplink transmission to the second base station.

Abstract
Certain aspects of the present disclosure provide procedures for power sharing, scaling, and power headroom reporting in dual connectivity operations. According to certain aspects, a method of wireless communication by a user equipment (UE) is provided. The method generally includes determining a maximum available transmit power of the UE, semi-statically configuring a first minimum guaranteed power available for uplink transmission to a first base station and a second minimum guaranteed power available for uplink transmission to a second base station, and dynamically determining a first maximum transmit power available for uplink transmission to the first base station and a second maximum transmit power available for uplink transmission to the second base station based, at least in part, on the maximum available transmit power of the UE, the first minimum guaranteed power, and the second minimum guaranteed power.
