Abstract
A base station transmits at least one message to a wireless device. The at least one message comprises one or more configuration parameters of: a plurality of cells grouped into a plurality of groups, and a pathloss reference of a secondary cell. The base station receives uplink signals on the secondary cell. Transmission power of the uplink signals in the secondary cell is determined, at least in part, employing measurement of downlink signals of the pathloss reference of the secondary cell.
Claims20
A method comprising:
- receiving, by a wireless device from a base station, at least one radio resource control (RRC) message comprising one or more configuration parameters of a plurality of cells comprising a cell, wherein the one or more configuration parameters comprise:
- a cell index identifying the cell;
- and
- a pathloss reference index identifying a plurality of downlink subcarriers as a pathloss reference of the cell;
- measuring the plurality of downlink subcarriers identified by the pathloss reference index to determine a pathloss for uplink transmission of at least one uplink signal;
- determining an uplink transmission power for the at least one uplink signal based on the pathloss;
- and
- transmitting, by the wireless device via a plurality of uplink subcarriers, the at least one uplink signal employing the uplink transmission power.

A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- receive, from a base station, at least one radio resource control (RRC) message comprising one or more configuration parameters of a plurality of cells comprising a cell, wherein the one or more configuration parameters comprise:
- a cell index identifying the cell;
- and
- a pathloss reference index identifying a plurality of downlink subcarriers as a pathloss reference of the cell;
- measure the plurality of downlink subcarriers identified by the pathloss reference index to determine a pathloss for uplink transmission of at least one uplink signal;
- determine an uplink transmission power for the at least one uplink signal based on the pathloss;
- and
- transmit, via a plurality of uplink subcarriers, the at least one uplink signal employing the uplink transmission power.
