Title:
METHOD AND APPARATUS FOR ADAPTING A CHANNEL SENSING THRESHOLD
Document Type and Number:
WIPO Patent Application WO/2021/158030
Kind Code:
A1
Abstract:
Methods and apparatuses for adapting a channel sensing threshold in a wireless communication system operating with shared spectrum channel access. A method for operting a base station (BS) includes determining whether an antenna configuration for channel sensing is omni-directional or directional and determining a channel sensing threshold. The channel sensing threshold includes a first part of the channel sensing threshold being common for omni-directional and directional antenna configurations, and a second part of the channel sensing threshold depending on the antenna configuration. The method further includes performing a channel sensing procedure based on the antenna configuration and the channel sensing threshold and transmitting downlink (DL) data over a channel based on the channel being sensed as idle in the channel sensing procedure.
