Techniques for Node Directed Uplink (UL) Cancellation and Channel Access in Unlicensed Bands - A simplified explanation of the abstract

This abstract first appeared for US patent application 17593750 titled 'Techniques for Node Directed Uplink (UL) Cancellation and Channel Access in Unlicensed Bands

Simplified Explanation

The patent application describes a technique for wireless communications in a wireless system. Here are the key points:

• The technique involves receiving cancellation capability information from a first user device and unlicensed frequency transmission capability information from a second user device.
• The first user device transmits an uplink transmission over an unlicensed frequency band.
• If the second user device requires a higher priority uplink transmission, the technique schedules an uplink cancellation time for the first user device and an uplink transmission time for the second user device.
• An uplink cancellation request is then transmitted to the first user device based on the scheduled uplink cancellation time.
• Finally, an uplink transmission time for the higher priority uplink transmission is transmitted to the second user device based on the scheduled uplink transmission time.

Potential applications of this technology:

• Wireless communication systems that require efficient management of uplink transmissions.
• Networks where multiple user devices need to share limited resources.
• Systems that prioritize certain uplink transmissions over others based on their importance.

Problems solved by this technology:

• Efficiently managing uplink transmissions in wireless systems with limited resources.
• Prioritizing higher priority uplink transmissions over lower priority ones.
• Coordinating the scheduling of uplink transmissions between multiple user devices.

Benefits of this technology:

• Improved efficiency in managing uplink transmissions, leading to better overall system performance.
• Enhanced ability to prioritize important uplink transmissions, ensuring critical data is transmitted in a timely manner.
• Effective coordination of uplink transmission scheduling, minimizing conflicts and maximizing resource utilization.

Original Abstract Submitted

A technique for wireless communications in a wireless system including: receiving, from a first user device, cancellation capability information, receiving, from a second user device, unlicensed frequency transmission capability information, receiving, from the first user device, an uplink transmission over an unlicensed frequency band, determining, a need for a higher priority uplink transmission by the second user device, scheduling an uplink cancellation time for the first user device based on the cancellation capability information and unlicensed frequency transmission capability information, scheduling an uplink transmission time for the second user device based on the cancellation capability information and unlicensed frequency transmission capability information, transmitting an uplink cancellation request to the first user device based on the scheduled uplink cancellation time, and transmitting an uplink transmission time for the higher priority uplink transmission to the second user device based on the scheduled uplink transmission time.
