A wireless device receives radio resource control messages including pathloss reference indicators for sounding reference signal (SRS) resource sets of a first cell. Each SRS resource set includes SRS resources, each identified by a respective SRS resource identifier, and is identified by a respective SRS resource set identifier. Each of the SRS resource set is associated with a respective pathloss reference indicator, of the pathloss reference indicators, that indicates: a cell identifier identifying a pathloss reference cell, and a RS identifier identifying a pathloss RS. SRSs are transmitted, via SRS resources of a first SRS resource set of the SRS resource sets, with a transmission power determined based on a first pathloss RS of a first pathloss reference cell. The first pathloss RS and the first pathloss reference cell are indicated by a first pathloss reference indicator, of the pathloss reference indicators, associated with the first SRS resource set.
