DOWNLINK CONTROL CHANNEL SIGNALING FOR UL COEXISTENCE OF MULTIPLE SERVICE TYPES

Abstract:

Systems, devices, and techniques for controlling uplink transmissions including cancelling previously scheduled transmissions are described. A described technique includes receiving, by a user equipment (UE), a configuration information that provides a search space set configuration associated with a control resource set (CORESET) to monitor for an uplink cancellation indication; receiving, by the UE, scheduling information that schedules one or more uplink transmissions; monitoring, by the UE via a physical downlink control channel (PDCCH), for the uplink cancellation indication based on the configuration information; receiving, by the UE via the PDCCH, a downlink control information (DCI) message that comprises the uplink cancellation indication; and cancelling, by the UE, at least part of the one or more uplink transmissions in response to the uplink cancellation indication.
