Techniques for Node Directed Uplink (UL) Cancellation and Channel Access in Unlicensed Bands

A device comprising:

• an antenna;
• a radio operably coupled to the antenna;
• and
• a processor operably coupled to the radio;
• wherein the device is configured to:
• receive, from a first user device, cancellation capability information;
• receive, from a second user device, unlicensed frequency transmission capability information;
• receive, from the first user device, an uplink transmission over an unlicensed frequency band;
• determine, a need for a higher priority uplink transmission by the second user device;
• schedule an uplink cancellation time for the first user device based on the cancellation capability information and the unlicensed frequency transmission capability information;
• schedule an uplink transmission time for the second user device based on the cancellation capability information and the unlicensed frequency transmission capability information;
• transmit an uplink cancellation request to the first user device based on the scheduled uplink cancellation time;
• and
• transmit an uplink transmission time for the higher priority uplink transmission to the second user device based on the scheduled uplink transmission time.

An integrated circuit, comprising circuitry configured to cause a wireless device to receive, from a first user device, cancellation capability information;

• receive, from a second user device, unlicensed frequency transmission capability information;
• receive, from the first user device, an uplink transmission over an unlicensed frequency band;
• determine, a need for a higher priority uplink transmission by the second user device;
• schedule an uplink cancellation time for the first user device based on the cancellation capability information and the unlicensed frequency transmission capability information;
• schedule an uplink transmission time for the second user device based on the cancellation capability information and the unlicensed frequency transmission capability information;
• transmit an uplink cancellation request to the first user device based on the scheduled uplink cancellation time;
• and
• transmit an uplink transmission time for the higher priority uplink transmission to the second user device based on the scheduled uplink transmission time.
