COMMUNICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18024876 titled 'COMMUNICATION SYSTEM

Simplified Explanation

The patent application describes a method for a user equipment (UE) to maintain information for configuring the timing of fixed frame periods (FFPs) in a listen-before-talk (LBT) procedure when communicating with a radio access network (RAN).

  • The UE performs a clear channel assessment (CCA) to check if the communication channel is clear before transmitting data.
  • If the CCA indicates that the channel is clear, the UE initiates a channel occupancy time (COT) within the next FFP and starts transmitting the data.
  • However, if the UE receives an indication from the RAN node to stop the transmission, it ceases transmitting the data.


Original Abstract Submitted

A method is disclosed in which a user equipment (UE) that communicates with a radio access network (RAN) maintains information for configuring timing of fixed frame period (FFPs) for a listen-before-talk (LBT) procedure. When the UE has data to be transmitted, it performs a clear channel assessment, CCA, to determine if a communication channel is clear. When the CCA indicates that the communication channel is clear a channel occupancy time, COT, is initiated for the UE within a subsequent FFP and transmission of the data commences. However, transmission of the data ceases following receipt of an indication, from a node of the RAN, that the transmission should be stopped.
