CHANNEL OCCUPANCY TIME (COT) STRUCTURE INDICATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18057786 titled 'CHANNEL OCCUPANCY TIME (COT) STRUCTURE INDICATION

Simplified Explanation

This patent application describes a system for a user equipment (UE) to receive channel occupancy time structure information (COT-SI) in a shared spectrum. The COT-SI includes information about the duration of the channel occupancy time (COT), the end symbol of the COT, and a pause indication for the COT.

  • The UE can receive COT-SI in both connected and idle states.
  • The COT-SI includes slot format indication for one or more slots.
  • The COT-SI signaling is hierarchical, with a set of short COT tables configured for the UE.
  • The UE receives concatenation of COT-SI signaling that identifies index values in a control channel corresponding to the set of COT tables.
  • The UE can communicate based on the occurrence of a COT.

Potential applications of this technology:

  • Wireless communication systems operating in shared spectrum.
  • Internet of Things (IoT) devices that need to efficiently use available spectrum.
  • Mobile devices that need to optimize their communication in shared spectrum environments.

Problems solved by this technology:

  • Efficient utilization of shared spectrum by providing information about channel occupancy time.
  • Improved communication reliability by indicating the end of channel occupancy and pauses.
  • Simplified signaling for UE devices by using a hierarchical approach to COT-SI.

Benefits of this technology:

  • Enhanced spectrum efficiency by allowing UEs to adapt their communication based on COT information.
  • Improved reliability and reduced interference by indicating the end of channel occupancy and pauses.
  • Simplified implementation for UE devices by using a hierarchical approach to COT-SI signaling.


Original Abstract Submitted

This disclosure provides systems, methods and apparatus for a user equipment (UE), operating in a shared spectrum in a connected state or an idle state, to receive a channel occupancy time structure information (COT-SI) which includes one or more of a COT duration, a COT end symbol, and a COT pause indication, in addition to slot format indication for one or more slots. Some aspects described herein define a hierarchical approach to COT structure information (COT-SI) signaling. For example, a UE may be configured with a set of short COT tables using remaining minimum system information (RMSI) signaling and may receive concatenation of COT-SI signaling identifying index values in a control channel corresponding to one or more of the set of COT tables. Based on receiving COT-SI signaling, the UE may communicate in accordance with an occurrence of a COT.
