METHOD AND DEVICE FOR CONFIGURING SL HARQ RTT TIMER IN NR V2X - A simplified explanation of the abstract

This abstract first appeared for US patent application 18051265 titled 'METHOD AND DEVICE FOR CONFIGURING SL HARQ RTT TIMER IN NR V2X

Simplified Explanation

The abstract describes a method and device for wireless communication using sidelink discontinuous reception (DRX). The method involves obtaining a sidelink DRX configuration, receiving sidelink control information (SCI) and data from a second device, determining a value for a sidelink DRX hybrid automatic repeat request (HARD) round trip time (RTT) timer, and starting the sidelink DRX retransmission timer.

  • The method involves obtaining a sidelink DRX configuration, which includes a value for a sidelink DRX retransmission timer.
  • Sidelink control information (SCI) for scheduling of second SCI and a physical sidelink shared channel (PSSCH) is received from a second device through a physical sidelink control channel (PSCCH).
  • The second device sends the second SCI and data through the PSSCH.
  • The value of the sidelink DRX HARD RTT timer is determined as zero when information related to the next retransmission resource is not included in the first SCI.
  • The sidelink DRX retransmission timer is started.

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 data transmission in scenarios where sidelink communication is required.

Problems Solved

  • The method solves the problem of efficient scheduling and transmission of sidelink control information and data in wireless communication.
  • It addresses the issue of determining the value for the sidelink DRX HARD RTT timer when information about the next retransmission resource is not included in the first SCI.

Benefits

  • The method allows for improved efficiency and reliability in wireless communication by utilizing sidelink DRX.
  • It enables better resource allocation and scheduling of sidelink control information and data.
  • The use of the sidelink DRX retransmission timer helps in reducing delays and improving overall system performance.


Original Abstract Submitted

Provided are a method for performing wireless communication by a first device, and a device for supporting same. The method may comprise: obtaining a sidelink (SL) discontinuous reception (DRX) configuration including a value of a SL DRX retransmission timer; receiving, from a second device through a physical sidelink control channel (PSCCH), first sidelink control information (SCI) for scheduling of second SCI and a physical sidelink shared channel (PSSCH); receiving, from the second device through the PSSCH, the second SCI and data; determining a value of a SL DRX hybrid automatic repeat request (HARD) round trip time (RTT) timer as zero, based on that information related to a next retransmission resource is not included in the first SCI; and starting the SL DRX retransmission timer.
