Communications device, infrastructure equipment, and methods for determining whether to transmit first data using first uplink communication resources

A communications device for operating in a wireless communications network, the communications device comprising:

• a transmitter configured to transmit signals via a wireless access interface provided by an infrastructure equipment in a cell of the wireless communications network,
• a receiver configured to receive signals via the wireless access interface, and
• a controller configured to control the transmitter and the receiver so that the communications device is operable:
• to receive at a time A an uplink grant indication, the uplink grant indication indicating first uplink communication resources of the wireless access interface allocated for transmission of first data by the communications device,
• to receive at a time B an uplink cancellation indication (UL-CI), the UL-CI indicating second uplink communication resources, the second uplink communication resources including at least a portion of the first uplink communication resources allocated for transmission of second data, and
• in response to receiving the uplink grant indication and the uplink cancellation indication, to determine to transmit the first data using the first uplink communication resources based on one relationship between the time A at which the uplink grant indication was received and the time B at which the UL-CI was received and determine to refrain from transmitting the first data using the first uplink communication resources based on another relationship between the time A at which the uplink grant indication was received and the time B at which the UL-CI was received, including:
• when the time A precedes the time B by less than a first pre-determined time, transmitting the first data using the first uplink communication resources, and
• when the time A is after the time B and is less than a second pre-determined time later than the time B, transmitting the first data using the first uplink communication resources.

• to receive an uplink grant indication, the uplink grant indication indicating first uplink communication resources of the wireless access interface allocated for transmission of first data by the communications device,
• to receive an uplink cancellation indication (UL-CI), the UL-CI indicating resources within a reference uplink region, the reference uplink region associated with the UL-CI and defining uplink communication resources,
• to determine that the first uplink communication resources are within the resources indicated by the UL-CI,
• to determine a time window associated with the UL-CI,
• to determine that the uplink grant indication was received within the time window associated with the UL-CI, and
• in response to determining that the uplink grant indication was received within the time window associated with the UL-CI, to transmit the first data using the first uplink communication resources.
