METHOD AND DEVICE FOR RECEIVING SIDELINK RETRANSMISSION PACKET IN NR V2X - A simplified explanation of the abstract

This abstract first appeared for US patent application 17920994 titled 'METHOD AND DEVICE FOR RECEIVING SIDELINK RETRANSMISSION PACKET IN NR V2X

Simplified Explanation

The abstract describes a method for a first device to carry out sidelink communication. The method involves starting a timer for a PSFCH resource when sidelink HARQ feedback information is not transmitted to a second device based on a first priority. Once the timer expires, a second timer is started for a sidelink HARQ retransmission packet for a PSSCH or SCI. The first device then receives the sidelink HARQ retransmission packet from the second device.

  • The method allows for efficient sidelink communication between devices.
  • It ensures that sidelink HARQ feedback information is transmitted based on priority.
  • Timers are used to control the transmission and reception of sidelink HARQ retransmission packets.
  • The method can be implemented in wireless communication systems.

Potential Applications

  • This method can be applied in cellular networks to improve sidelink communication between devices.
  • It can be used in Internet of Things (IoT) applications where devices need to communicate with each other directly.
  • The method can be implemented in vehicle-to-vehicle (V2V) communication systems to enhance data transmission reliability.

Problems Solved

  • The method solves the problem of efficiently transmitting sidelink HARQ feedback information based on priority.
  • It addresses the issue of ensuring reliable reception of sidelink HARQ retransmission packets.
  • The method solves the challenge of coordinating communication between multiple devices in a sidelink scenario.

Benefits

  • The method improves the overall efficiency and reliability of sidelink communication.
  • It allows for prioritization of sidelink HARQ feedback information transmission.
  • The use of timers ensures proper timing and coordination of sidelink HARQ retransmission packets.
  • The method can enhance the performance of wireless communication systems.


Original Abstract Submitted

Provided, according to one embodiment of the present disclosure, is a method for a first device carrying out sidelink communication. The method comprises the steps of: starting a first timer associated with a PSFCH resource on the basis that sidelink HARQ feedback information is not transmitted to a second device through the PSFCH resource on the basis of a first priority associated with the sidelink HARQ feedback information; on the basis that the first timer has expired, starting a second timer associated with a sidelink HARQ retransmission packet for a PSSCH or SCI; and receiving the sidelink HARQ retransmission packet from the second device after the second timer starts.
