摘要
A plurality of resource pools and/or a plurality of transmission and/or reception points may be used in wireless communications. Different pathloss references may be used for different resource pools and/or different transmission and/or reception points. A wireless device may receive one or more messages indicating a plurality of power control parameter sets each associated with a respective resource pool and/or a respective transmission and/or reception point. The wireless device may control a transmission power based on a pathloss reference associated with a resource pool and/or a transmission and/or reception point.

A wireless device may use an SRI field, in DCI, to determine a pathloss reference signal for its future uplink transmission power determination, for example, if the DCI comprises the SRI field. The wireless device may determine/use a default pathloss reference, for example, if the wireless device receives DCI from which an SRI field is omitted. At least in some wireless communications, the wireless device may determine, for the TB, a transmission power based on a default pathloss reference signal mapped to a power control parameter set, among the power control parameter sets, with a power control parameter set index that is equal to zero, for example, if the DCI does not comprise the SRI field.
