CATEGORY-2 LISTEN-BEFORE-TALK (LBT) OPTIONS FOR NEW RADIO-UNLICENSED (NR-U) - A simplified explanation of the abstract

This abstract first appeared for US patent application 18325314 titled 'CATEGORY-2 LISTEN-BEFORE-TALK (LBT) OPTIONS FOR NEW RADIO-UNLICENSED (NR-U)

Simplified Explanation

This patent application describes wireless communication systems and methods for performing a listen-before-talk (LBT) process before transmitting data in a frequency spectrum shared by multiple network operating entities.

  • The first wireless communication device receives a first communication signal from a second wireless communication device.
  • The first wireless communication device determines a measurement period in a gap duration between the first and second communication signals, specifically in a portion adjacent to the start time of the second communication signal.
  • The first wireless communication device performs an LBT process based on a channel measurement taken during the determined measurement period.
  • The first wireless communication device then transmits a second communication signal to the second wireless communication device based on the LBT process.


Original Abstract Submitted

Wireless communications systems and methods related to performing listen-before-talk (LBT) before a transmission after a link switch in a frequency spectrum shared by multiple network operating entities are provided. A first wireless communication device receives, from a second wireless communication device, a first communication signal. The first wireless communication device determines a first measurement period in a first portion of a gap duration between the first communication signal and a second communication signal, the first portion being adjacent to a start time of the second communication signal. The first wireless communication device performs an LBT based at least in part on a first channel measurement in the first measurement period. The first wireless communication device transmits, to the second wireless communication device, the second communication signal based on the LBT.
