MECHANISM FOR SHARING CHANNEL OCCUPANCY TIME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18571075 titled 'MECHANISM FOR SHARING CHANNEL OCCUPANCY TIME
Simplified Explanation: The patent application describes a method for sharing channel occupancy time (COT) among devices for sidelink transmission over unlicensed spectrum bands.
- First device determines which second devices will share the COT for transmission.
- Information about the COT is transmitted to the selected devices.
- Second devices determine transmission gaps within the COT and perform LBT/CCA on the unlicensed spectrum bands.
- This method improves spectrum efficiency and prevents resource waste.
Key Features and Innovation:
- Sharing channel occupancy time (COT) among devices for sidelink transmission.
- Determining transmission gaps within the COT for efficient spectrum usage.
- Performing LBT/CCA on unlicensed spectrum bands to avoid interference.
- Improving spectrum efficiency and preventing resource waste.
Potential Applications: This technology can be applied in:
- Wireless communication systems
- Internet of Things (IoT) devices
- Smart city infrastructure
Problems Solved:
- Efficient sharing of channel occupancy time (COT) among devices.
- Preventing resource waste in spectrum usage.
- Avoiding interference in unlicensed spectrum bands.
Benefits:
- Improved spectrum efficiency.
- Enhanced communication reliability.
- Optimal resource utilization.
Commercial Applications: Potential commercial applications include:
- Wireless network providers
- IoT device manufacturers
- Smart city developers
Questions about Channel Occupancy Time (COT): 1. What is the significance of sharing COT among devices for sidelink transmission? 2. How does determining transmission gaps within the COT improve spectrum efficiency?

Original Abstract Submitted
According to embodiments of the present disclosure, a first device determines one or more second devices to share a channel occupancy time (COT) for a sidelink transmission over an unlicensed spectrum bands. The first device transmits the information which indicates the COT to be shared by the first device and the one or more second devices. The second device determines a transmission gap within the COT and performs a LBT/CCA on the unlicensed spectrum bands based on the determined gap. In this way, it achieves sharing the COT among SL devices. It can improve spectrum efficiency and avoid resource waste.
