A wireless device receives configuration parameters comprising: a monitoring periodicity; and a first parameter indicating one or more symbols. A downlink control channel is monitored for a downlink control information indicating a slot format of an active bandwidth part. The monitoring is during at least one monitoring symbol determined based on the monitoring periodicity and the first parameter. The downlink control information comprising one or more fields indicating the slot format is received. One or more transport blocks in one or more uplink symbols determined based on a first slot format is transmitted via the active bandwidth part.
