METHOD AND DEVICE FOR TRANSMITTING PRACH IN NR V2X - A simplified explanation of the abstract

This abstract first appeared for US patent application 18035692 titled 'METHOD AND DEVICE FOR TRANSMITTING PRACH IN NR V2X

Simplified Explanation

The abstract describes an operating method for a device in a wireless communication system. Here are the key points:

  • The method involves transmitting a random access (RA) preamble to a base station.
  • The device receives a random access response (RAR) message from the base station in response to the RA preamble.
  • The device then transmits a physical uplink shared channel (PUSCH) to the base station as a response to the RAR message.
  • The device receives downlink control information (DCI) from the base station, which is generated based on a radio network temporary identifier (RNTI) related to the RA procedure.
  • The device determines if there is overlapping between sidelink (SL) communication and physical uplink control channel (PUCCH) transmission related to the DCI.
  • If there is overlapping, the device transmits a PUCCH to the base station based on the overlapping.

Potential applications of this technology:

  • This operating method can be applied in wireless communication systems to improve the efficiency and reliability of communication between devices and base stations.
  • It can be used in various wireless communication networks, such as cellular networks, IoT networks, and vehicle-to-vehicle communication systems.

Problems solved by this technology:

  • The method addresses the issue of efficient random access and response in wireless communication systems.
  • It solves the problem of coordinating sidelink communication and physical uplink control channel transmission to avoid interference and ensure reliable communication.

Benefits of this technology:

  • The method improves the overall performance and reliability of wireless communication systems by optimizing the random access procedure.
  • It allows for efficient transmission and reception of control information, leading to better coordination and reduced interference.
  • The technology enables seamless communication between devices and base stations, enhancing the user experience and enabling various applications in wireless networks.


Original Abstract Submitted

An operating method for a first device () in a wireless communication system is presented. The method may comprise the steps of: transmitting an RA preamble to a base station (); receiving, from the base station (), a random access response (RAR) message related to the RA preamble; transmitting, to the base station (), a physical uplink shared channel (PUSCH) as a response to the RAR message; receiving, from the base station (), downlink control information (DCI) generated on the basis of a radio network temporary identifier (RNTI) related to the RA procedure, as a response to the PUSCH; determining overlapping between sidelink (SL) communication and physical uplink control channel (PUCCH) transmission related to the DCI; and transmitting a PUCCH to the base station () on the basis of the overlapping.
