Techniques for transmit power allocation in dual connectivity

A method for wireless communication at a user equipment (UE), comprising:

• establishing a first wireless connection with a first wireless device;
• establishing a second wireless connection with the first wireless device or a second wireless device, wherein the first wireless connection and the second wireless connection operate in a dual connectivity mode;
• identifying a first energy efficiency metric associated with the first wireless connection and a second energy efficiency metric associated with the second wireless connection;
• identifying one or more parameters associated with a transmit power of communications at the UE;
• comparing the first energy efficiency metric and the second energy efficiency metric;
• and
• allocating a first power resource to the first wireless connection and a second power resource to the second wireless connection based at least in part on an absence of voice traffic at the UE, or whether voice traffic at the UE is communicated via the first wireless connection, the second wireless connection, or a combination thereof.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• establish a first wireless connection with a first wireless device;
• establish a second wireless connection with the first wireless device or a second wireless device, wherein the first wireless connection and the second wireless connection operate in a dual connectivity mode;
• identify a first energy efficiency metric associated with the first wireless connection and a second energy efficiency metric associated with the second wireless connection;
• identify one or more parameters associated with a transmit power of communications at the UE;
• compare the first energy efficiency metric and the second energy efficiency metric;
• allocate a first power resource to the first wireless connection, a second power resource to the second wireless connection, or both, based at least in part on the comparison, the one or more parameters, or a combination thereof;
• and
• transmit a control message indicating a first set of one or more characteristics associated with wireless communications at the UE based at least in part on the first power resource, the second power resource, or a combination thereof, the control message further indicating a first message buffer queue associated with the first wireless connection and a second message buffer queue associated with the second wireless connection, the second message buffer queue different from the first message buffer queue.
