Sidelink Channel Occupancy Time Sharing - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240381395 titled 'Sidelink Channel Occupancy Time Sharing
Simplified Explanation: The patent application discusses apparatuses, systems, and methods for managing sidelink unlicensed band (SL-U) cyclic prefix extension (CPE) starting positions and identifier (ID) restrictions for channel time occupancy (COT) sharing in 5G NR systems and beyond.
Key Features and Innovation:
- Systems and mechanisms for COT sharing for PSFCH multi-channel transmission
- Determination of CPE starting positions in SL-U
- ID restrictions for SL-U COT sharing
- Decision-making on when to use Type 2A, Type 2B, and/or Type 2C in SL-U COT sharing
Potential Applications: This technology can be applied in wireless communication systems to efficiently manage channel time occupancy and enhance data transmission in SL-U scenarios.
Problems Solved: The technology addresses the challenges of coordinating COT sharing among multiple user equipment (UE) devices in SL-U environments, ensuring efficient use of available resources.
Benefits:
- Improved spectral efficiency
- Enhanced reliability of data transmission
- Optimal utilization of channel resources
Commercial Applications: The technology can find commercial applications in telecommunications, IoT devices, and other wireless communication systems where efficient COT sharing is essential for data transmission.
Prior Art: Readers interested in prior art related to this technology can explore research papers, patents, and industry publications on COT sharing and resource allocation in wireless communication systems.
Frequently Updated Research: Stay updated on the latest advancements in COT sharing mechanisms, resource allocation strategies, and spectral efficiency enhancements in wireless communication systems.

Original Abstract Submitted
apparatuses, systems, and methods for sidelink unlicensed band (sl-u) cyclic prefix extension (cpe) starting position as well as identifier (id) restrictions for channel time occupancy (cot) sharing, including systems, methods, mechanisms for cot sharing for psfch multi-channel transmission, cpe starting position determination in sl-u, id restrictions for sl-u cot sharing, and determination of when to use type 2a, type 2b, and/or type 2c in sl-u cot sharing, e.g., in 5g nr systems and beyond. a ue may initiate channel access in a sl-u via an nr downlink type a or type b multi-channel access procedure to perform multi-channel psfch transmissions. the ue may secure a cot and when the cot is initiated by psfch type 1 channel access, the cot may not be shared with other ues, the cot may be shared with a corresponding ue, or the cot may be shared with ues expecting feedback during the cot.
