Abstract: A wireless communication system is disclosed. Specifically, a channelization method in a whitespace band and an apparatus for the same are disclosed. A method for providing whitespace operation information includes transmitting, by a first station (STA) to a second STA, a frame including a TV whitespace high throughput (TVHT) operation information field. The TVHT operation information field includes primary channel number, channel width, channel center frequency segment 0 and channel center frequency segment 1 subfields. A channel center frequency of frequency segment 0 or frequency segment 1 is determined based on a channel start frequency. The channel start frequency is determined as a function of a TV channel index corresponding to the frequency segment 0 or a TV channel index corresponding to the frequency segment 1.

Abstract: Proposed are a method and a device for transmitting and receiving important update information of another AP through an ML element in a WLAN system. Specifically, a receiving MLD receives a basic ML element from a transmitting MLD over a first link. The receiving MLD decodes the basic ML element. The basic ML element includes a profile field of the second transmitting STA. The profile field of the second transmitting STA includes a first CSF presence field. When the value of the first CSF presence field is set to 0, the profile field of the second transmitting STA includes a first CSF field. The first CSF field includes information about the current change sequence number of the second transmitting STA.

Abstract: A method performed by a first STA in a wireless local area network (WLAN) according to various embodiments may comprise transmitting or receiving a TWT setup request message and a TWT setup response message. The first STA may perform a TWT operation on the basis of the TWT setup request message and the TWT setup response message. The TWT setup request message and the TWT setup response message may be transmitted or received through a first link included in multiple links. The first STA may set the first link to be in an awake state in order to perform the TWT operation through the first link.

Abstract: In a wireless local area network (WLAN) system, a transmitting multi-link device (MLD) may defer the transmission of a PPDU on a first link, even if a back-off counter of a non-primary link reaches zero, as long as a back-off counter of a primary link does not reach zero. When the transmission of the PPDU is deferred, the back-off counter may be kept at zero.
