Transmitting with an Uplink Transmission Power Based on a Pathloss Reference Identified by a Pathloss Index

摘要

A wireless device receives at least one radio resource control message from a base station. The at least one radio resource control message comprises configuration parameters of a cell. The configuration parameters comprise: a cell index identifying the cell; and an index identifying downlink subcarriers as a pathloss reference signal of the cell. The downlink subcarriers identified by the index are measured to determine a pathloss for uplink transmission of at least one uplink signal. An uplink transmission power for the at least one uplink signal is determined based on the pathloss. The wireless device transmits, via uplink subcarriers, the at least one uplink signal employing the uplink transmission power.
