METHOD AND DEVICE FOR RESERVING RESOURCES IN NR V2X - A simplified explanation of the abstract
This abstract first appeared for US patent application 17922831 titled 'METHOD AND DEVICE FOR RESERVING RESOURCES IN NR V2X
Simplified Explanation
The patent application describes a method for establishing sidelink communication between devices. Here is a simplified explanation of the abstract:
- The method involves transmitting a first SCI (Sidelink Control Information) to one or more devices using PSCCH (Physical Sidelink Control Channel).
- Data and a second SCI, different from the first SCI, are transmitted to the devices using PSSCH (Physical Sidelink Shared Channel) associated with the PSCCH.
- PSFCH (Physical Sidelink Feedback Channel) resources are determined for receiving sidelink HARQ (Hybrid Automatic Repeat Request) feedbacks associated with the data. The determination is based on the slot index associated with the PSSCH and the sub-channel index.
- Sidelink HARQ feedbacks associated with the data are received from the devices using the PSFCH resources.
- Based on the ratio of the total number of bits associated with ACK (acknowledgment) relative to the total number of bits associated with the sidelink HARQ feedbacks, a decision is made to reselect a sidelink transmission resource associated with the PSCCH or the PSSCH. This decision is made if the ratio is equal to or less than a threshold value.
Potential applications of this technology:
- This method can be applied in wireless communication systems where devices need to establish sidelink communication for various purposes such as device-to-device communication, vehicle-to-vehicle communication, or IoT (Internet of Things) applications.
- It can be used in scenarios where reliable and efficient transmission of data and feedback is required between devices.
Problems solved by this technology:
- The method addresses the challenge of establishing sidelink communication between devices in a wireless communication system.
- It provides a mechanism for transmitting data and receiving feedback reliably and efficiently.
Benefits of this technology:
- The method allows for efficient transmission of data and feedback by utilizing specific channels and resources.
- It enables devices to establish reliable sidelink communication, ensuring the successful delivery of data and feedback.
- The reselection of transmission resources based on the ratio of ACK bits to sidelink HARQ feedback bits helps optimize the overall communication performance.
Original Abstract Submitted
According to an embodiment of the present disclosure, provided is a method in which a first device establishes sidelink communication. The method can comprise the steps of: transmitting first SCI to at least one device by means of at least one PSCCH; transmitting data and second SCI which is different from the first SCI to the at least one device by means of at least one PSSCH associated with the at least one PSCCH; determining a plurality of PSFCH resources for receiving a plurality of sidelink HARQ feedbacks associated with the data, on the basis of an index of a slot associated with the at least one PSSCH and an index of a sub-channel; receiving, from the at least one device, at least one sidelink HARQ feedback associated with the data on the basis of at least one PSFCH resource among the plurality of PSFCH resources; and determining to reselect a sidelink transmission resource associated with the at least one PSCCH or the at least one PSSCH, on the basis that a ratio of the total number of bits associated with ACK relative to the total number of bits associated with the plurality of sidelink HARQ feedbacks is equal to or less than a threshold value.
