Abstract
Systems and methods for signaling Pathloss Reference RS are provided. In some embodiments, a method performed by a wireless device for identifying which Transmission and Reception Point (TRP) an update refers to includes: receiving a configuration of a first and second Sounding Reference Signal (SRS) resource sets associated to a first and second TRP; receiving a control message indicating a Physical Uplink Shared Channel (PUSCH) pathloss reference update; where the control message comprises an indication of which TRP the update refers to. In some embodiments: the control message comprises a Medium Access Control (MAC) Control Element (CE); the pathloss reference update comprises a PUSCH Pathloss Reference Signal (RS) ID field; the pathloss reference update comprises one or more SRS Resource Indicator (SRI) ID fields. In this way, pathloss can be updated for SRIs associated with different SRS resource sets for per TRP power control in PUSCH repetition to multiple TRP.
