Method and apparatus for multi-channel operation in wireless local area network system

摘要

Disclosed are a method and apparatus for multi-channel operation, performed by an access point (AP), in a WLAN system, the method includes: transmitting channel assignment information to a plurality of stations (STAs), in which the channel assignment information is for assigning at least one of a first channel and a second channel to each of the plurality of STAs; transmitting channel activity information to the plurality of STAs, in which the channel activity information is for indicating an activity duration where the AP transmit or receive a frame through each of the first channel and the second channel; and transmitting or receiving a frame through the first channel or the second channel on the basis of the channel activity information.

1. A method for operating on at least one operation channel, performed by an access point (AP), in a wireless local area network (WLAN) system, the method comprising:
transmitting operating channel information and channel activity information to a plurality of stations (STAs), wherein the operating channel information is for indicating at least one of a first channel and a second channel as the at least one operation channel to each of the plurality of STAs, the channel activity information being for indicating an activity duration where the AP transmit or receive a frame through each of the first channel and the second channel; and transmitting or receiving a frame through the first channel or the second channel on the basis of the channel activity information, wherein the channel activity information includes:
a channel indicator,an activity offset indicating a point of time when the activity duration first starts for a channel indicated by the channel indicator,a length of the activity duration, andan interval between the activity durations.
