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.

說明書

The wireless device 2012 may determine/compute/calculate a transmission power, for example, based on the pathloss reference RS. The wireless device 2012 may determine/compute/calculate a downlink path loss estimate for the transmission power based on a quality (e.g., L1-RSRP or L3-RSRP or a higher filtered RSRP of) of a pathloss RS (e.g., provided/indicated by a higher layer parameter referenceSignal, ssb-index, csi-RS-Index, NZP-CSI-RS-ResourceId in FIG. 17) indicated by the pathloss reference RS. The wireless device 2012 may use the downlink path loss estimate in determining/computing/calculating the transmission power for transmission of the transport block 1921, 1923, 2022, or 2032. The transmission power may comprise (or may be based on) the downlink path loss estimate. The wireless device 2012 may determine/calculate/compute a higher filtered RSRP (e.g., L3-RSRP) value of the pathloss RS for the downlink path loss estimate (or a path loss measurement). The wireless device 2012 may determine/calculate/compute the higher filtered RSRP for transmission of the transport block 1921, 1923, 2022, or 2032.

The wireless device 1911 may send/transmit a transport block 1923 (e.g., PUSCH at time T_11 in FIG. 19), for example, after or in response to receiving the activation command 1922 (e.g., after time T1 in FIG. 19). The wireless device 1911 may send/transmit the transport block 1923, for example, after using information comprised in the activation command 1922 (or after the activation command is active).
