US 12,192,917 B2 · Techniques for reporting power headroom for multiple uplink shared channel repetitions

Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive control signaling scheduling multiple uplink transmission repetitions including first and second sets of repetitions associated with first and second sounding reference signal (SRS) resource sets, respectively. The UE may determine first and second power headroom (PHR) values for the respective sets of repetitions, where at least the second PHR value is determined in accordance with a first rule as either an actual value based on a transmission power of one of the uplink transmission repetitions or a virtual value based on default transmission power settings, the first rule pertaining to PHR determination for multiple sets of repetitions corresponding to multiple SRS resource sets. The UE may generate a PHR report that includes the first PHR value, the second PHR value, or both, and may transmit the PHR report to the base station.

Dependent claims

A user equipment (UE), comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
receive, from a network device, control signaling scheduling a plurality of uplink transmission repetitions, the plurality of uplink transmission repetitions comprising a first set of repetitions associated with a first sounding reference signal resource set and a second set of repetitions associated with a second sounding reference signal resource set;
determine a first power headroom value for the first set of repetitions and a second power headroom value for the second set of repetitions, at least the second power headroom value being determined as a virtual value based at least in part on one of an ordered pair of sets of default transmission power settings;
generate a power headroom report that includes the first power headroom value, the second power headroom value, or both;
and
transmit the power headroom report to the network device.
