SIDELINK RESOURCE ALLOCATION IN UNLICENSED SPECTRUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18249360 titled 'SIDELINK RESOURCE ALLOCATION IN UNLICENSED SPECTRUM

Simplified Explanation

The patent application describes methods, systems, and devices for configuring a user equipment (UE) operating in unlicensed spectrum with a set of component carriers (CCs) for sidelink communications using the unlicensed spectrum.

  • UE can select a CC from a set of candidate CCs for sidelink communications in unlicensed spectrum.
  • UE can select a resource in the selected CC for sidelink communication.
  • UE can select multiple candidate resources for sidelink communication based on sensing and using a resource selection configuration.
  • UE can indicate the reservation of a candidate resource by indicating the CC and the location of the reserved resource within the carrier.
  • UE can transmit a sidelink message using a selected candidate resource in the unlicensed spectrum.

Potential Applications

  • This technology can be applied in wireless communication systems to support sidelink communications in unlicensed spectrum.
  • It can be used in various IoT (Internet of Things) applications where devices need to communicate with each other using unlicensed spectrum.

Problems Solved

  • The technology solves the problem of configuring a UE operating in unlicensed spectrum for sidelink communications.
  • It addresses the issue of selecting the appropriate CC and resource for efficient sidelink communication.
  • It provides a solution for indicating the reservation of a candidate resource in the unlicensed spectrum.

Benefits

  • The technology allows UEs to efficiently configure themselves for sidelink communications in unlicensed spectrum.
  • It enables UEs to select the most suitable CC and resource for their sidelink communication needs.
  • The ability to indicate the reservation of a candidate resource helps in avoiding interference and ensuring reliable communication.


Original Abstract Submitted

Methods, systems, and devices for wireless communication are described to support configuring a user equipment (UE) operating in unlicensed spectrum with a set of component carriers (CCs) for sidelink communications using the unlicensed spectrum. In a first example, a UE may select a CC from the set of candidate CCs, for example, using a carrier selection configuration, and may select a resource in the CC for a sidelink communication. In a second example, a UE may select multiple candidate resources for a sidelink communication, for example, using a resource selection configuration and based on sensing performed by the UE. To indicate the reservation of a candidate resource, the UE may indicate both a CC in which the reserved resource is located and a location of the reserved resource within the carrier. The UE may transmit a sidelink message using a selected candidate resource in the unlicensed spectrum.
