Power headroom report for uplink split bearer communications

A method of wireless communication, comprising:

• receiving a first power headroom report (PHR) from a user equipment (UE) at a first time;
• transmitting an uplink (UL) grant comprising radio resources based at least in part on the first PHR;
• receiving an adjusted PHR from the UE at a second time different from the first time, wherein the adjusted PHR is based at least in part on a characteristic associated with a link between a base station and a UE;
• and
• transmitting an adjusted UL grant comprising radio resources based at least in part on the adjusted PHR.

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• the processor and memory configured to:
• transmit a first power headroom report (PHR) to a first base station on a first link of a split bearer and to a second base station on a second link of the split bearer;
• evaluate a characteristic associated with the first link or the second link after transmitting the first PHR;
• adjust a transmit power value transmitted in the first PHR associated with the first link or the second link, or both based at least in part on the evaluating;
• and
• transmit an adjusted PHR to the first base station or the second base station, or both based at least in part on the evaluating.
