RX UE(S) ASSISTED CHANNEL ACCESS PROCEDURE FOR SIDELINK OPERATION IN UNLICENSED BAND - A simplified explanation of the abstract

This abstract first appeared for US patent application 18197715 titled 'RX UE(S) ASSISTED CHANNEL ACCESS PROCEDURE FOR SIDELINK OPERATION IN UNLICENSED BAND

Simplified Explanation

The patent application describes a system and method for a targeted receiving User Equipment (UE) to determine if a corresponding transmitting UE has a future reserved resource block. Here are the key points:

  • The receiving UE performs a Listen Before Talk (LBT) sensing to find a time period when an unlicensed channel is not being used.
  • This unoccupied time period can be used by the transmitting UE for future reserved sidelink transmission.
  • The receiving UE sends a reservation signal to the transmitting UE during the unoccupied time period to reserve the unlicensed channel.
  • The receiving UE switches to a receiving mode before or at the reserved slot boundary of the future reserved resource block.

Potential applications of this technology:

  • This technology can be used in wireless communication systems to efficiently allocate resources for future reserved sidelink transmissions.
  • It can improve the reliability and performance of communication between User Equipment devices.

Problems solved by this technology:

  • The system solves the problem of efficiently determining if a transmitting UE has a future reserved resource block.
  • It addresses the issue of finding an unoccupied time period in an unlicensed channel for the transmitting UE to use.

Benefits of this technology:

  • The system improves the overall efficiency of resource allocation in wireless communication systems.
  • It enhances the reliability and performance of communication between User Equipment devices.
  • The method allows for better coordination between transmitting and receiving UEs, leading to improved communication quality.


Original Abstract Submitted

A system and a method are disclosed for determining, by a targeted receiving User Equipment (UE), that a corresponding transmitting UE has a future reserved resource block. The receiving UE may perform a Listen Before Talk (LBT) sensing to identify a time period when an unlicensed channel is unoccupied and can be used by the corresponding transmitting UE for the future reserved sidelink transmission. The receiving UE may transmit a reservation signal for the unlicensed channel to the corresponding transmitting UE, during at least a portion of the time period when the unlicensed channel is unoccupied. Further, the receiving UE may, switch, to a receiving mode prior to or at a reserved slot boundary of the future reserved resource block.
