1. A method of operating of a radio access node to provide transmit power control commands to a wireless device for use in uplink transmission, comprising:
transmitting on a downlink control channel an indication to the wireless device for a cell that operates in unlicensed frequency spectrum, the indication including a dynamic transmit power control command that indicates a downlink-uplink allocation of upcoming subframes in the cell that operates in the unlicensed frequency spectrum, the indication indicating that the dynamic transmit power control command is one of an accumulative or absolute transmit power control command; and
the dynamic transmit power control command being applicable to physical uplink shared channel, short physical uplink control channel, enhanced physical uplink control channel, and sounding reference signal transmissions.
