A wireless device receives a first downlink control information indicating a grant for transmission of one or more first transport blocks via a first bandwidth part during a transmission time. The first downlink control information indicates the transmission time. A second downlink control information indicating switching from the first bandwidth part to a second bandwidth part at a switching time is received. A switch is performed, at the switching time, from the first bandwidth part to the second bandwidth part as an active bandwidth part in response to the second downlink control information. The grant indicated by the first downlink control information is ignored in response to the switching time of the switch being earlier than the transmission time indicated by the first downlink control information.
