Exploitation of transmitter (tx) power for each band dual up-link (ul) carrier aggregation (ca)

A method comprising:

• receiving, at a network device from a user equipment (UE), an indication of a UE capability to support a per-band maximum power for a radio band combination (BC) used by the UE;
• determining whether the UE supports per-band maximum power for the radio BC based on the indication of the UE capability;
• and
• in response to determining the UE supports per-band maximum power for the radio BC, determining a total UE transmission power based on a sum of a maximum power of each band in the radio BC.

An apparatus comprising:

• at least one processor;
• and
• at least one memory storing instructions thereon that, when executed by the at least one processor, cause the apparatus to perform at least:
• indicating, to a network device, support for a maximum power based on a per-band power class (PC) for a radio band combination (BC) including two or more uplink carriers;
• and
• applying, in uplink power control, maximum user equipment (UE) transmission according to the per-band PC for each band in the radio BC.
