CHANNEL ACCESS PRIORITY FOR SIDELINK AND RELAY COMMUNICATIONS IN NR-U - A simplified explanation of the abstract

This abstract first appeared for US patent application 18450831 titled 'CHANNEL ACCESS PRIORITY FOR SIDELINK AND RELAY COMMUNICATIONS IN NR-U

Simplified Explanation

The abstract of this patent application describes wireless communication devices, systems, and methods that help a user equipment (UE) determine the channel access priority (CAPC) to use for a data radio bearer (DRB) on sidelink, which includes multiple quality of service (QoS) flows for transmission. The UE can receive an indication from a base station (BS) regarding the CAPC to use, or it can determine the CAPC itself based on a rule. The UE then maps the QoS flows to the DRB and transmits them using the selected CAPC.

  • The patent application focuses on mechanisms to assist a UE in determining the CAPC for a DRB on sidelink.
  • The UE can receive an indication from a base station or determine the CAPC itself based on a rule.
  • The UE maps the QoS flows to the DRB and transmits them using the selected CAPC.

Potential applications of this technology:

  • Wireless communication systems and devices that involve multiple QoS flows for transmission.
  • Sidelink communication scenarios where determining the CAPC for a DRB is crucial.
  • Networks that require efficient channel access prioritization for data transmission.

Problems solved by this technology:

  • Ensuring efficient channel access prioritization for multiple QoS flows on sidelink.
  • Simplifying the process of determining the CAPC for a DRB.
  • Improving the overall performance and reliability of wireless communication systems.

Benefits of this technology:

  • Improved efficiency in channel access prioritization for data transmission.
  • Enhanced reliability and performance of wireless communication systems.
  • Simplified process for determining the CAPC for a DRB on sidelink.


Original Abstract Submitted

Wireless communication devices, systems, and methods related to mechanisms to aid a user equipment (UE) in determining the channel access priority (CAPC) to use for a data radio bearer (DRB) on sidelink that includes multiple quality of service (QoS) flows for a transmission. The UE may receive an indication from a base station (BS) regarding what CAPC to use, or it may itself determine the CAPC based on a rule. The UE may map the plurality of QoS flows to the DRB and transmit the QoS flows using the DRB and the selected CAPC.
