UNLICENSED BAND USAGE BY BOTH UNLICENSED RADIO TECHNOLOGY AND A HIGHER PRIORITY RADIO TECHNOLOGY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18275673 titled 'UNLICENSED BAND USAGE BY BOTH UNLICENSED RADIO TECHNOLOGY AND A HIGHER PRIORITY RADIO TECHNOLOGY
Simplified Explanation
The patent application describes a method for protecting a higher priority radio technology (such as 3GPP New Radio or NR in Unlicensed spectrum) when co-existing with an unlicensed radio technology (such as Wi-Fi) in the same frequency band.
- Transmitting a Request to Send (RTS) frame within a Time Division Duplexing (TDD) radio frame on a cell served by the radio access node in an unlicensed frequency band.
- Transmitting a downlink transmission or receiving an uplink transmission from a wireless communication device on the cell served by the radio access node in the unlicensed spectrum during a period of time indicated in the RTS frame.
Potential Applications
This technology could be applied in cellular communications systems to ensure the protection of higher priority radio technologies when operating in the same frequency band as unlicensed radio technologies.
Problems Solved
1. Interference between different radio technologies operating in the same frequency band. 2. Ensuring the reliability and performance of higher priority radio technologies in the presence of unlicensed radio technologies.
Benefits
1. Enhanced co-existence of different radio technologies in the same frequency band. 2. Improved quality of service for higher priority radio technologies. 3. Efficient utilization of spectrum resources.
Potential Commercial Applications
This technology could be utilized by cellular network operators, equipment manufacturers, and wireless communication device providers to enhance the performance and reliability of cellular communications systems in the presence of unlicensed radio technologies.
Possible Prior Art
One potential prior art could be methods for managing interference in co-existing radio technologies, but specific techniques for protecting a higher priority radio technology in the presence of unlicensed radio technologies may be novel.

Original Abstract Submitted
Systems and methods are disclosed herein that enable protecting a higher priority radio technology (e.g., 3GPP New Radio (NR) or NR in Unlicensed spectrum (NR-U)) when co-existing with an unlicensed radio technology (e.g., the Wi-Fi wireless network technology) operating in the same frequency band. In one embodiment, a method of operation of a radio access node of radio access network of a cellular communications system comprises transmitting a Request to Send (RTS) frame within a Time Division Duplexing (TDD) radio frame on a cell served by the radio access node in an unlicensed frequency band. The method further comprises transmitting a downlink transmission to a wireless communication device or receiving an uplink transmission from the wireless communication device, on the cell served by the radio access node in the unlicensed spectrum during a period of time that corresponds to a duration of time indicated in the RTS frame.
