System and method for simultaneous UL cancellation and UL CI monitoring
An example method for wireless communication includes: receiving, by a wireless station, an uplink transmission from a wireless device of a set of two or more wireless devices; determining, by the wireless station, a need for a higher priority uplink transmission; determining, by the wireless station, a minimum cancellation processing time for the set of two or more wireless devices; and transmitting an uplink cancellation request to the set of two or more wireless devices based on the minimum cancellation processing time.

determine an amount of uplink monitoring resources that are available for uplink cancellation request monitoring and prioritization request monitoring, the uplink monitoring including:
resources for monitoring a wireless device search space (UESS), the UESS resources monitoring a Physical Downlink Control Channel (PDCCH) scheduling for an uplink interval corresponding to a first priority for a first application running on the wireless device, or higher priority traffic of another application running on the wireless device, and allowing prioritization between applications with different priorities running on the wireless device, and
resources for monitoring a common search space (CSS), the CSS resources monitoring a Group Common PDCCH that includes an uplink cancellation indication that allows prioritization between wireless devices with different priorities;
determine a maximum amount of the uplink monitoring resources useable for monitoring for the uplink cancellation indication on the CSS;
