CHANNEL OCCUPANCY TIME (COT) MAINTENANCE FOR SIDELINK COMMUNICATIONS IN UNLICENSED BANDS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17740059 titled 'CHANNEL OCCUPANCY TIME (COT) MAINTENANCE FOR SIDELINK COMMUNICATIONS IN UNLICENSED BANDS
Simplified Explanation
- The patent application describes a method of wireless communication using a first wireless communication device. - The method aims to maintain a channel occupancy time (COT) in a shared frequency band during a physical sidelink feedback channel (PSFCH) instance. - The first wireless communication device transmits a first sidelink (SL) communication in a portion of the COT based on a listen-before-talk (LBT) approach. - The first SL communication includes SL communication information (SCI) that indicates a second wireless communication device to transmit a signal in a gap symbol preceding a PSFCH resource. - The first wireless communication device receives the signal from the second wireless communication device during the gap symbol. - The first wireless communication device then transmits a second SL communication in another portion of the COT based on the LBT approach. - The second portion of the COT occurs after the PSFCH resource.
Original Abstract Submitted
A method of wireless communication performed by a first wireless communication device may maintain a channel occupancy time (COT) in a shared frequency band during at least one physical sidelink feedback channel (PSFCH) instance. In some aspects, the method includes transmitting, in a first portion of a COT based on a listen-before talk (LBT), a first sidelink (SL) communication comprising SL communication information (SCI), the SCI indicating a second wireless communication device to transmit a signal in at least one gap symbol preceding a PSFCH resource. The method further includes receiving, from the second wireless communication device, the signal during the at least one gap symbol. The method further includes transmitting, in a second portion of the COT based on the LBT, a second SL communication, wherein the second portion of the COT is subsequent to the PSFCH resource.
