NETWORK CODED SIDELINK COMMUNICATION USING RESERVED RESOURCES FOR RETRANSMISSION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17532894 titled 'NETWORK CODED SIDELINK COMMUNICATION USING RESERVED RESOURCES FOR RETRANSMISSION

Simplified Explanation

The patent application describes a method for a sidelink device to perform network coded sidelink transmission without increasing resource overhead. Here are the key points:

  • The sidelink device can use reserved resources for retransmission of a packet to perform network coded sidelink transmission.
  • The reserved resources can be reused when retransmission is not needed, based on feedback from the initial sidelink transmission.
  • The sidelink device can transmit network coded sidelink data received from other sidelink devices using the reserved retransmission resources.
  • The sidelink device can also transmit a network coded transmission that includes a retransmission of its own sidelink data and sidelink data from other devices.

Potential Applications

  • This technology can be applied in wireless communication systems that use sidelink transmissions, such as device-to-device communication or vehicle-to-vehicle communication.
  • It can be used in scenarios where retransmission resources are limited or need to be efficiently utilized.

Problems Solved

  • The method solves the problem of resource overhead in sidelink transmissions by utilizing reserved retransmission resources.
  • It addresses the challenge of efficiently using limited retransmission resources in wireless communication systems.

Benefits

  • By reusing reserved retransmission resources, the method reduces resource overhead in sidelink transmissions.
  • It allows for network coded sidelink transmission, which can improve the reliability and efficiency of communication.
  • The method enables efficient utilization of limited retransmission resources, leading to improved overall system performance.


Original Abstract Submitted

A sidelink device can perform a network coded sidelink transmission without increasing resource overhead by using resources originally reserved for retransmission of a packet, The sidelink device can reuse the reserved resources when retransmission is not needed based on feedback of the initial sidelink transmission. In one aspect, the sidelink device can use reserved retransmission resources to transmit a network coded transmission of sidelink data received from other sidelink devices. In one aspect, the sidelink device can use the reserved retransmission resources to transmit a network coded transmission including a retransmission of the sidelink device's own sidelink data and sidelink data from other devices.
