DEVICE FOR TRANSMITTING DATA USING SIDELINK IN WIRELESS COMMUNICATION SYSTEM AND OPERATION METHOD THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 17953846 titled 'DEVICE FOR TRANSMITTING DATA USING SIDELINK IN WIRELESS COMMUNICATION SYSTEM AND OPERATION METHOD THEREOF

Simplified Explanation

The present disclosure describes methods and apparatuses for performing vehicle to everything (V2X) communication using sidelink technology.

  • The method involves receiving a physical sidelink control channel (PSCCH) and a first physical sidelink shared channel (PSSCH) during a first symbol period from a first device to a second device.
  • The PSCCH and first PSSCH are received based on a first transmission configuration indication (TCI) state assigned to the PSCCH.
  • The first symbol period includes specific symbols dedicated to receiving the PSCCH and first PSSCH.
  • The second device then receives a second PSSCH during a second symbol period that follows the first symbol period, based on a second TCI state.
  • The second symbol period includes specific symbols dedicated to receiving the second PSSCH.

Potential applications of this technology:

  • V2X communication in autonomous vehicles: This technology can enable seamless and efficient communication between autonomous vehicles, allowing them to exchange critical information such as location, speed, and intentions.
  • Traffic management systems: By facilitating V2X communication, this technology can enhance traffic management systems by enabling real-time data exchange between vehicles and infrastructure, leading to improved traffic flow and congestion management.
  • Emergency services: Sidelink-based V2X communication can enable faster and more reliable communication between emergency vehicles and other vehicles on the road, improving response times and overall safety.

Problems solved by this technology:

  • Limited bandwidth: Sidelink-based V2X communication optimizes the use of available bandwidth by assigning specific symbols for receiving control and shared channels, ensuring efficient and reliable data transmission.
  • Interference mitigation: By using transmission configuration indication (TCI) states, this technology helps mitigate interference and improve the overall quality of V2X communication.
  • Synchronization and coordination: The use of specific symbol periods for receiving different channels helps in synchronizing and coordinating communication between devices, ensuring seamless and reliable V2X communication.

Benefits of this technology:

  • Improved communication reliability: By utilizing specific symbols and TCI states, this technology enhances the reliability of V2X communication, reducing the chances of data loss or interference.
  • Efficient use of bandwidth: The allocation of specific symbols for different channels optimizes the use of available bandwidth, maximizing the efficiency of V2X communication.
  • Enhanced safety and efficiency: Sidelink-based V2X communication enables faster and more accurate exchange of information between vehicles, leading to improved safety and efficiency on the roads.


Original Abstract Submitted

The present disclosure provides methods and apparatuses for performing sidelink-based vehicle to everything (V2X) communication. In some embodiments, an operation method includes receiving, by the second device from the first device during a first symbol period, a physical sidelink control channel (PSCCH) and a first physical sidelink shared channel (PSSCH), based on a first transmission configuration indication (TCI) state assigned to the PSCCH. The first symbol period includes first symbols on which the PSCCH and the first PSSCH are received. The operation method further includes receiving, by the second device from the first device during a second symbol period that follows the first symbol period, a second PSSCH, based on a second TCI state. The second symbol period includes second symbols on which the second PSSCH is received.
