Techniques for Channel Access by a User Device with Uplink (UL) Cancellation in Unlicensed Bands - A simplified explanation of the abstract

This abstract first appeared for US patent application 17593754 titled 'Techniques for Channel Access by a User Device with Uplink (UL) Cancellation in Unlicensed Bands

Simplified Explanation

The abstract describes a technique for wireless communications in a wireless system. Here is a simplified explanation of the abstract:

• The technique involves transmitting unlicensed frequency transmission capability information from a second user device.
• Based on this information, the second user device receives an uplink transmission time.
• The second user device also receives a request to transmit a reservation transmission in an unlicensed frequency band, taking into account the cancellation time capability of a first user device and the uplink transmission time.
• The second user device then transmits the reservation transmission in the unlicensed frequency band.
• Additionally, the second user device transmits a higher priority uplink transmission in the same unlicensed frequency band.

Potential applications of this technology:

• Wireless communication systems that utilize unlicensed frequency bands.
• Networks where multiple user devices need to coordinate their transmissions in an efficient manner.
• Internet of Things (IoT) devices that operate in unlicensed frequency bands.

Problems solved by this technology:

• Efficient utilization of unlicensed frequency bands by coordinating transmission times between user devices.
• Avoiding interference and collisions between multiple user devices transmitting in the same frequency band.

Benefits of this technology:

• Improved efficiency and reliability of wireless communications in unlicensed frequency bands.
• Increased capacity for simultaneous transmissions in the same frequency band.
• Reduced interference and collisions between user devices.
• Enhanced performance of IoT devices operating in unlicensed frequency bands.

Original Abstract Submitted

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