METHOD AND DEVICE FOR TRANSMITTING FRAME THROUGH DETERMINATION OF CHANNEL EXPANSION IN BROADBAND WIRELESS COMMUNICATION NETWORK

Title:

METHOD AND DEVICE FOR TRANSMITTING FRAME THROUGH DETERMINATION OF CHANNEL EXPANSION IN BROADBAND WIRELESS COMMUNICATION NETWORK

Document Type and Number:

WIPO Patent Application WO/2020/222584

Kind Code:

A1

Abstract:

A method for operating a first communication node in a wireless communication network may comprise: a step for measuring the channel busy ratio of a first channel; a step for allowing fallback transmission of a first frame in the first channel on the basis of information about the channel busy ratio of the first channel; a step for performing a channel sensing operation in the first channel and a second channel; and a step for performing fallback transmission of the first frame in the first channel when, as a result of the channel sensing operation, the state of the first channel is an idle state and the state of the second channel is a busy state.
