1. A device comprising:
a processing system of a first network element including a processor, the first network element using a first inter-radio access technology (IRAT); and
a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations comprising:
receiving capability information for a user equipment (UE) communicating on a network that includes the first network element, the capability information indicating that the UE supports communication using the first IRAT and a second IRAT;
providing to the UE a first uplink power configuration for first data transmissions between the UE and the first network element;
sending the capability information to a second network element using the second IRAT;
providing to the UE a second uplink power configuration for second data transmissions between the UE and the second network element; and
performing a closed loop control procedure comprising:
obtaining uplink performance information comprising UE demand for each of the first IRAT and the second IRAT and an estimate of a remaining UE uplink transmission power for each of the first IRAT and the second IRAT, and
adjusting, based on the uplink performance information, a first transmit power control (TPC) value for the first data transmissions and a second TPC value for the second data transmissions to allocate the remaining UE uplink transmission power between the first IRAT and the second IRAT.
