Abstract: In certain scenarios, resource preemption may occur. A user equipment (UE) is configured to monitor for a preemption indication based on a specific downlink configuration. This configuration provides information about whether preemption is identified within a data space in terms of resource blocks. The UE receives data transmissions from a base station at different times and a preemption indication in a group common physical downlink control channel. Based on this preemption indication and the downlink configuration, the UE determines if a portion of the shared downlink resources occupied by the initial data is preempted from use. If the resources are not preempted, the UE proceeds to decode the initial data.
