Patent attributes
A wireless device transmits a first message comprising a preamble and a transport block. The wireless device receives, during a time window, a first downlink control information (DCI) scheduling a response to the first message. The first DCI indicates a first transmit power control (TPC) command value. A decoding failure of the response and an expiry of a timing alignment timer is determined. The wireless device receives, based on the determining and during the time window, a second DCI rescheduling the response. The second DCI indicates a second TPC command value. The wireless device selects, based on a decoding success of the response rescheduled by the second DCI, the second TPC command value as a transmit power adjustment value among the first TPC command value and the second TPC command value. The wireless device transmits a feedback using a transmit power determined based on the transmit power adjustment value.
