Prioritized Messaging and Resource Selection in Vehicle-to-Vehicle (V2V) Sidelink Communication - A simplified explanation of the abstract

This abstract first appeared for US patent application 17993752 titled 'Prioritized Messaging and Resource Selection in Vehicle-to-Vehicle (V2V) Sidelink Communication

Simplified Explanation

The patent application describes a method and system for communication between a Generation Node-B (gNB) and User Equipment (UE) in a wireless network, specifically for vehicle-to-vehicle (V2V) sidelink transmissions.

  • The gNB allocates a resource pool of physical resource blocks (PRBs) and sub-frames for V2V sidelink transmissions.
  • The UE sends an uplink control message to the gNB, requesting a V2V sidelink transmission of a prioritized message.
  • The gNB selects specific PRBs and sub-frames for the V2V sidelink transmission of the prioritized message.
  • The gNB transmits a downlink control message to the UE and other UEs, indicating the selected PRBs and sub-frames.
  • The downlink control message also instructs the other UEs to mute their sidelink transmissions in the selected PRBs and sub-frames, enabling the V2V sidelink transmission of the prioritized message.

Potential Applications

  • This technology can be applied in V2V communication systems, allowing vehicles to exchange prioritized messages efficiently.
  • It can be used in intelligent transportation systems to enhance safety and coordination between vehicles on the road.
  • The system can also find applications in emergency response scenarios, where quick and reliable communication between vehicles is crucial.

Problems Solved

  • Prioritizing and efficiently transmitting V2V messages in a wireless network can be challenging, especially when multiple vehicles are involved.
  • This technology solves the problem of resource allocation for V2V sidelink transmissions, ensuring that prioritized messages are transmitted effectively.
  • It also addresses the issue of interference from other UEs by instructing them to mute their sidelink transmissions in specific PRBs and sub-frames.

Benefits

  • The method allows for efficient and reliable communication between vehicles, ensuring that prioritized messages are transmitted without interference.
  • By allocating specific PRBs and sub-frames, the system optimizes the use of available resources, improving overall network performance.
  • The technology enhances the coordination and safety of vehicles on the road, particularly in scenarios where quick and reliable communication is essential.


Original Abstract Submitted

Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may allocate a resource pool of physical resource blocks (PRBs) and sub-frames for vehicle-to-vehicle (V2V) sidelink transmissions. The gNB may receive, from a UE, an uplink control message that indicates that the UE requests a V2V sidelink transmission of a prioritized message. The gNB may select, for the V2V sidelink transmission of the prioritized message, one or more PRBs and one or more sub-frames. The gNB may transmit, to the UE and to other UEs, a downlink control message that indicates: the selected PRBs, the selected sub-frames, and that the other UEs are to mute sidelink transmissions in the selected PRBs in the selected sub-frames to enable the V2V sidelink transmission of the prioritized message.
