1. A method for communication in a wireless system, comprising:
scheduling, by a wireless station, a first uplink (UL) 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 that uses resources overlapping with the first UL transmission;
determining, by the wireless station, a reference region, within which a UL cancellation indication (CI) is to be applied;
determining, by the wireless station, a set of UL resources in the reference region for cancellation, wherein at least a subset of the UL resources in the reference region are interlaced;
sending, via a downlink (DL) control channel, indication of the determined set of UL resources for cancellation; and
receiving, at the wireless station, the higher priority uplink transmission via at least a subset of the determined set of cancelled UL resources.
