摘要： 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.

摘要： One example according to the present specification relates to a method for identifying the format of a PPDU in a wireless LAN (WLAN) system. A receiving STA may receive a first PPDU. The receiving STA may check at least one extra tone of at least one symbol of the first PPDU. The receiving STA may determine, on the basis of the at least one extra tone, the format of the first PPDU as a repeated PPDU format. Thereafter, the receiving STA may receive a second PPDU including the same data as the first PPDU.

摘要： A transmitting multi-link device (MLD) in a wireless local area network system enables a first station (STA) to perform a back-off operation again without transmitting PPDU, if a second STA is in the middle of receiving even when a back-off counter (BC) of the first STA becomes 0. The first STA and the second STA are included in the same transmitting MLD. The first STA operates on a first link and the second STA operates on a second link. The first and second links are included in a non-simultaneous transmit and receive (NSTR) link pair.

摘要： In a wireless local area network (LAN) system, a sharing access point (AP) may transmit a first selection frame to a first shared AP and transmit a second selection frame to a second shared AP on the basis of information relating to channels between a reception station (STA) and the first shared AP and between the reception STA and the second shared AP. The sharing AP may receive a first selection response frame from the first shared AP. The sharing AP may determine to use the first shared AP in multi-AP transmission on the basis of the first selection response frame.
