A wireless device receives a downlink control information comprising: a first field indicating a number of scheduled time intervals; a modulation and coding scheme field; a transmit power control field; and a listen before talk (LBT) field indicating timing information for performing an LBT procedure. The LBT procedure for transmission in the number of scheduled time intervals is performed based on the timing information. A transmission power of each time interval in the number of scheduled time intervals is determined based on a same closed loop adjustment factor and the transmit power control field, wherein the transmission power of each time interval of the number of scheduled time intervals is adjusted in response to a total transmit power for a respective time interval exceeding a power value. The wireless device transmits, in each time interval of number of scheduled time intervals, employing the modulation and coding scheme field.
