User equipment and method for enhanced uplink power control

摘要

Embodiments of user equipment and methods for improved uplink transmission power management and scheduling, are generally described herein. For example, in an aspect, a method of uplink power management is presented, the method includes determining whether a total desired transmission power exceeds a total configured maximum output power for a subframe. When the total desired transmission power exceeds the total configured maximum output power, the method includes allocating a minimum proactive power limitation to each serving cell, assigning a remaining power to one or more channels based on priority, and computing a total power assignment based on the allocating and the assigning.

1. User Equipment (UE) comprising:
processing circuitry arranged to:
determine whether a total desired transmission power over a plurality of channels exceeds a total configured maximum output power for a subframe when the UE is scheduled for concurrent physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH) transmission by an enhanced node B (eNB) in the subframe; andin response to a determination that the total desired transmission power over the plurality of channels is less than the total configured maximum output power for the subframe:
initially allocate a minimum non-zero proactive power to each of the plurality of channels; andallocate any remaining power of a power budget to the plurality of channels based on priorities of the plurality of channels, and a transceiver configured by the processing circuitry to transmit the plurality of channels in accordance the minimum proactive power and the remaining power allocations, wherein the PUCCH of a primary cell (PCell) is allocated power as a first priority, PUSCH with downlink control information (DCI) of the PCell is allocated power as a second priority, and a PUSCH without DCI of a secondary cell (SCell) is allocated power as a lowest priority.
