Techniques are disclosed relating to handling preemptive data services in cellular wireless transmissions. In some embodiments, a device wirelessly transmits uplink data for a first data service during a time dimension duplex (TDD) scheduled transmission interval using a first frequency band. While transmitting, in these embodiments, the device also monitors a downlink control channel that uses a second frequency band that does not overlap with the first frequency band. The downlink control channel may be dedicated for preemption indicators that indicate another service is preempting scheduled resources. In response to detecting an indicator in the downlink control channel of communications for a second data service in the first frequency band during the scheduled transmission interval, the device may reduce the transmission of the uplink data on resources used for the communications for the second data service (e.g., by blanking or transmitting at a lower power).
