TPC command indication for multiple closed loops

A wireless device configured with multiple power control closed loops for a serving cell, the wireless device comprising:

• a receiver;
• and
• processing circuitry coupled to the receiver, the processing circuitry configured to:
• receive, via the receiver, an indication of a starting position of a transmit power control (TPC) command in a downlink control message and an indication of a number of bits used for indicating closed loop power control;
• receive, via the receiver, a downlink control message comprising a plurality of TPC commands;
• obtain the plurality of TPC commands from the downlink control message based on the received indication of the starting position of the TPC command and the indication of the number of bits used for indicating closed loop power control;
• determine a particular power control closed loop of the plurality of power control closed loops to which the TPC command should be applied, the particular power control closed loop determined using the downlink control message;
• and
• update the particular power control closed loop using the TPC command.
