Title:
POWER HEADROOM REPORT BASED ON DYNAMIC PATHLOSS ESTIMATION
Document Type and Number:
WIPO Patent Application WO/2021/142432
Kind Code:
A1
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.
