METHOD AND APPARATUS FOR SIDELINK RESOURCE ALLOCATION IN UNLICENSED SPECTRUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17812704 titled 'METHOD AND APPARATUS FOR SIDELINK RESOURCE ALLOCATION IN UNLICENSED SPECTRUM
Simplified Explanation
The patent application describes methods and devices for allocating resources in unlicensed spectrum for sidelink communication in a wireless communication system. Here is a simplified explanation of the abstract:
- User equipment (UE) performs sensing on a sidelink interface to detect available resources.
- Based on the sensing, a set of available sidelink resources within a resource pool is determined.
- A slot within the sidelink resource pool is selected.
- A listen-before-talk (LBT) channel access procedure is performed before the selected slot to check for the presence of available resources.
- If the LBT procedure is successful and available resources are detected within the slot, the UE transmits using one of the available sidelink resources.
Potential applications of this technology:
- Wireless communication systems that utilize unlicensed spectrum.
- Internet of Things (IoT) devices that need to communicate with each other in a wireless network.
- Vehicle-to-vehicle (V2V) or vehicle-to-infrastructure (V2I) communication systems.
Problems solved by this technology:
- Efficient allocation of resources in unlicensed spectrum for sidelink communication.
- Avoiding interference with other devices operating in the same spectrum.
- Ensuring reliable communication by performing a listen-before-talk procedure.
Benefits of this technology:
- Improved utilization of unlicensed spectrum resources.
- Enhanced reliability of sidelink communication.
- Reduced interference with other devices operating in the same spectrum.
Original Abstract Submitted
Methods and apparatuses for sidelink (SL) resource allocation in unlicensed spectrum in a wireless communication system. A method of operating a user equipment (UE) includes performing sensing on a SL interface; determining, based on the sensing, a set of available SL resources within a SL resource pool; and selecting a slot within the SL resource pool. The method further includes performing a listen-before-talk (LBT) channel access procedure before the slot; determining a presence of available SL resources from the set of available SL resources within the slot; and transmitting, based on the LBT channel access procedure being successful and the presence being determined, in an available SL resource from the available SL resources within the slot.
