Abstract: A wireless device receives message(s) comprising one or more configuration parameters. The one or more configuration parameters indicate a plurality of power control parameter sets, wherein each power control parameter set of the plurality of power control parameter sets is identified by a respective power control parameter set index; and comprising a pathloss reference signal update parameter enabling an activation command to update pathloss reference signals of an uplink channel. Based on the one or more configuration parameters comprising the pathloss reference signal update parameter, a determination is made, for a power headroom report, of a pathloss reference signal mapped to a power control parameter set with a lowest power control parameter set index among power control parameter set indexes of the plurality of power control parameter sets. The power headroom report computed based on a pathloss estimation of the pathloss reference signal is transmitted.

Abstract: This disclosure provides systems, methods and apparatus for partitioning a physical sidelink shared channel (PSSCH) into multiple shortened PSSCHs (sPSSCHs) within a slot and selecting a transmit power for each sPSSCH. In one aspect, a transmitting user equipment (UE) may select the transmit power for each sPSSCH in accordance with an open loop power control operation. In some examples, the transmitting UE may select a common transmit power for each sPSSCH. Alternatively, the transmitting UE may perform independent power control operations for each sPSSCH and may cap variation in transmit power across sPSSCHs as a result of employing lower and upper bound transmit powers. Additionally, or alternatively, the transmitting UE may provide a default beta offset for the set of receiving UEs via sidelink control information (SCI) part one (SCI-1) and may provide beta offset updates via each SCI part two (SCI-2) transmission in the multiple sPSSCHs.
