Transmission repetition may be used in wireless communications. Control channel repetition may be used for scheduling communications between a base station and a wireless device. A time period between the control channel and the scheduled communications may be less than a threshold time period. The wireless device may determine, for communicating with the base station, a wireless resource corresponding to a default resource pool, a resource pool used for at least one repetition of the control channel, and/or based on a resource pool indicated via the control channel.
