Document Type and Number:

WIPO Patent Application WO/2020/226462

Kind Code:

A1

Abstract:

An operating method of a communication node in a wireless communication network comprises the steps of: performing a first monitoring operation on a first link and a second link during a preset period; performing a first random backoff operation in the first link for a first random backoff period, if the first link and the second link are in an idle state according to the result of the first monitoring operation; performing, in the second link, a second random backoff operation for a second random backoff period which is different from the first random backoff period in length; and transmitting a frame at the same point in time in the first link and the second link, if the first link is in an idle state according to the result of the first random backoff operation, and if the state of the second link is an idle state according to the execution result of the second random backoff operation.
