The wireless device starts the RAR window from a starting time based on the preamble transmission occasion, the first time offset, and a second time offset. The wireless device receives, during the RAR window, an RAR of the preamble transmission.

A predetermined rule may be used to determine on which downlink (DL) BWP of multiple active DL BWPs, and/or on which uplink (UL) BWP of multiple active UL BWPs, a message is to be sent. A wireless device and/or a base station may reduce the quantity of active DL BWPs and/or active UL BWPs to monitor for a response.

Abstract: Systems, apparatuses, and methods are described for wireless communications. A base station may transmit wireless device-specific downlink control information comprising HARQ feedback to a wireless device. Coordinating a plurality of HARQ feedbacks may result in complicated processing at the base station and/or a delay to schedule a HARQ feedback for the wireless device. The transmission of the downlink control information may not require HARQ feedback from a wireless device. By reducing the transmission of HARQ feedback, the channel capacity utilized for error correction transmissions can be reduced, thereby enhancing resource utilization.
