1. A baseband processor comprising:
one or more processors; and
memory storing instructions that when executed by the one or more processors, cause the one or more processors to perform operations comprising:
receiving a first configuration message from a base station of a wireless communications network, the first configuration message representing a search space set for monitoring the wireless communications network for an uplink cancellation message, wherein the search space set comprises a plurality of periodically repeating monitoring occasions;
receiving a first physical downlink control channel (PDCCH) from the wireless communications network, the first PDCCH comprising an uplink grant including scheduling information for an uplink transmission to the wireless communications network;
determining the search space set by determining an offset parameter between two adjacent ones of the periodically repeating monitoring occasions based on at least one of:
a time gap between an end of the uplink grant and an end of the uplink transmission indicated by the scheduling information, or
a duration of the uplink transmission indicated by the scheduling information;
monitoring the wireless communications network for the uplink cancellation message in accordance with the search space set, wherein the monitoring of the wireless communications network is triggered by the uplink grant and performed subsequent to the receipt of the uplink grant;
receiving a second PDCCH from the wireless communications network, the second PDCCH comprising the uplink cancellation message, the uplink cancellation message comprising an indication to cancel at least a portion of the uplink transmission; and
cancelling a transmission of at least the portion of the uplink transmission to the wireless communications network.
