TECHNIQUES FOR CROSS CHANNEL OCCUPANCY TIME HYBRID AUTOMATIC REPEAT REQUEST FEEDBACK TRANSMISSION FOR SIDELINK COMMUNICATION IN UNLICENSED SPECTRUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18031562 titled 'TECHNIQUES FOR CROSS CHANNEL OCCUPANCY TIME HYBRID AUTOMATIC REPEAT REQUEST FEEDBACK TRANSMISSION FOR SIDELINK COMMUNICATION IN UNLICENSED SPECTRUM

Simplified Explanation

The patent application describes techniques for transmitting feedback in sidelink communication using unlicensed spectrum.

  • The techniques involve a receiving user equipment (UE) receiving a transmission from a transmitting UE in a specific channel occupancy time (COT).
  • The receiving UE determines the timing for sending feedback based on the last slot of the COT.
  • The receiving UE also determines one or more feedback configurations.
  • The receiving UE then transmits a feedback message to the transmitting UE indicating the decoding of the transmission in either the first feedback occasion or a second feedback occasion based on the feedback configurations.


Original Abstract Submitted

Techniques for cross channel occupancy time (COT) hybrid automatic repeat request (HARQ) feedback transmission for sidelink communication in unlicensed spectrum may be performed. In an example, a receiving user equipment (UE) may receive, from a transmitting UE, a first transmission in a first channel occupancy time (COT). The receiving UE may also determine a first feedback occasion is after a last slot of the first COT. The receiving UE may also determine one or more feedback configurations. The receiving UE may also transmit, to the transmitting UE, a feedback message indicating decoding of the first transmission in the first feedback occasion or a second feedback occasion based on the one or more feedback configurations.
