Systems and methods for wireless communications are disclosed herein. In one embodiment, a base station configures a first uplink resource. The first uplink resource is defined using configuration parameters including at least one of a time-domain starting point of the first uplink resource, a time-domain duration of the first uplink resource, or a frequency-domain range of the first uplink resource. The base station transmits to a wireless communication device an indication that uplink transmission on a second uplink resource within the first uplink resource is canceled. The wireless communication device cancels the uplink transmission on the second uplink resource.
