MCS SELECTION FOR NETWORK CODING IN SIDELINK - A simplified explanation of the abstract

This abstract first appeared for US patent application 17541099 titled 'MCS SELECTION FOR NETWORK CODING IN SIDELINK

Simplified Explanation

The patent application describes techniques for selecting a packet to be network coded for sidelink communication. Here is a simplified explanation of the abstract:

  • A transmitting UE (User Equipment) can encode a packet using a higher MCS (Modulation and Coding Scheme) than the normal MCS used for encoding the packet without network coding.
  • The encoded packet is then transmitted to one or more receiving UEs and a network coding device over a sidelink data channel.
  • The transmitting UE also sends a network coding request flag associated with the packet to initiate retransmissions of the packet by the network coding device.

Potential Applications:

  • This technology can be applied in wireless communication systems where sidelink communication is used, such as in cellular networks or Internet of Things (IoT) devices.
  • It can be used to improve the reliability and efficiency of data transmission over sidelink channels.

Problems Solved:

  • Network coding allows for improved reliability and throughput in wireless communication systems by combining packets from different sources.
  • However, selecting the right packets for network coding can be challenging, especially when considering the modulation and coding schemes used.
  • This technology solves the problem of selecting packets for network coding by using a higher MCS for encoding, improving the overall performance of sidelink communication.

Benefits:

  • By using a higher MCS for encoding, the technology enables better error correction and higher data rates for network coded packets.
  • The retransmissions initiated by the network coding request flag further enhance the reliability of the transmitted packets.
  • Overall, this technology improves the efficiency and reliability of sidelink communication, leading to better user experience and increased network capacity.


Original Abstract Submitted

Aspects relate to techniques for MCS selection of a packet to be network coded for sidelink communication. A transmitting UE may encode a packet using an MCS that is greater than a normal MCS that may be used for encoding the packet without network coding. The transmitting UE may then transmit the encoded packet to one or more receiving UEs and a network coding device over a sidelink data channel. The transmitting UE may further transmit a network coding request flag associated with the packet to initiate one or more retransmissions of the packet by the network coding device.
