CLEAR CHANNEL ASSESSMENT METHOD AND DEVICE

Title:

CLEAR CHANNEL ASSESSMENT METHOD AND DEVICE

Document Type and Number:

WIPO Patent Application WO/2017/004994

Kind Code:

A1

Abstract:

The present invention provides a clear channel assessment method and device. The method comprises: traversing a first channel of a plurality of channels for carrier aggregation, wherein the first channel is one or more channels currently transmitting signals; computing an adjacent channel interference of the transmitted signals of the first channel to a second channel of the plurality of channels statistically, wherein the second channel is a channel not transmitting signals; and determining whether the second channel is idle according to a difference between a signal receiving power of the second channel and the adjacent channel interference. The present invention addresses the problem in which the probability of performing carrier aggregation is low when performed on an unlicensed spectrum, thus increasing the probability of performing carrier aggregation.
