This abstract first appeared for US patent application 18309516 titled 'SIDELINK CONTROL INFORMATION (SCI) IN NEW RADIO (NR) UNLICENSED

Simplified Explanation

The patent application describes a user equipment (UE) device that can operate in an unlicensed network for vehicle to everything (V2X) communication.

  • The UE device includes a V2X device, a baseband processor, or other network device.
  • The UE device can acquire a channel occupancy time (COT) for sidelink (SL) transmission in the unlicensed network.
  • The UE device can provide sidelink control information (SCI) to other UE devices.
  • The SCI is provided in two stages - a first stage SCI in a physical sidelink control channel (PSCCH) and a second stage SCI in a physical sidelink shared channel (PSSCH).
  • The first stage SCI or the second stage SCI can provide COT indications to receiving UE devices.
  • The COT indications enable COT sharing in a sidelink unlicensed COT (SL-U COT) for SL communication.
