METHOD AND APPARATUS FOR PERFORMING SL DRX OPERATION IN NR V2X - A simplified explanation of the abstract
This abstract first appeared for US patent application 18101063 titled 'METHOD AND APPARATUS FOR PERFORMING SL DRX OPERATION IN NR V2X
Simplified Explanation
The abstract describes a method and apparatus for wireless communication, specifically for sidelink communication. Sidelink discontinuous reception (DRX) configuration is obtained, which includes information about an SL DRX timer. The method involves receiving sidelink control information (SCI) and scheduling information for a physical sidelink shared channel (PSSCH) from a second apparatus through a physical sidelink control channel (PSCCH). Additionally, groupcast SCI and medium access control (MAC) packet data unit (PDU) related to the second apparatus are received through the PSCCH. Based on the sub-channel index and slot index, a physical sidelink feedback channel (PSFCH) resource is determined.
- The method enables wireless communication between two apparatuses using sidelink communication.
- Sidelink discontinuous reception (DRX) configuration is obtained, which includes information about an SL DRX timer.
- Sidelink control information (SCI) and scheduling information for a physical sidelink shared channel (PSSCH) are received through a physical sidelink control channel (PSCCH).
- Groupcast SCI and medium access control (MAC) packet data unit (PDU) related to the second apparatus are received through the PSCCH.
- A physical sidelink feedback channel (PSFCH) resource is determined based on the sub-channel index and slot index.
Potential Applications
- This technology can be applied in various wireless communication systems, such as cellular networks, IoT devices, and vehicle-to-vehicle communication.
- It can be used for efficient and reliable communication between devices in close proximity, enabling applications like real-time data sharing, collaborative tasks, and group communication.
Problems Solved
- The method solves the problem of establishing wireless communication between two apparatuses using sidelink communication.
- It addresses the challenge of managing sidelink discontinuous reception (DRX) and scheduling of physical sidelink shared channels (PSSCH) efficiently.
- The method also solves the problem of determining the physical sidelink feedback channel (PSFCH) resource based on sub-channel and slot indices.
Benefits
- The method provides a reliable and efficient way of wireless communication between two apparatuses using sidelink communication.
- It allows for optimized sidelink discontinuous reception (DRX) and scheduling of physical sidelink shared channels (PSSCH).
- The determination of physical sidelink feedback channel (PSFCH) resource based on sub-channel and slot indices ensures effective feedback communication.
Original Abstract Submitted
Proposed are a method by which a first apparatus performs wireless communication, and an apparatus supporting same. The method may comprise the steps of: obtaining a sidelink (SL) discontinuous reception (DRX) configuration including information related to an SL DRX timer; receiving, from a second apparatus through a physical sidelink control channel (PSCCH), second sidelink control information (SCI) and first SCI for scheduling a physical sidelink shared channel (PSSCH); receiving, from the second apparatus through the PSCCH, the second SCI related to groupcast and a medium access control (MAC) packet data unit (PDU); and determining, on the basis of an index of a sub-channel related to the PSSCH and an index of a slot, a physical sidelink feedback channel (PSFCH) resource.
