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.

Description

technical field [0001] The present invention relates to a wireless communication system, and more particularly, to a channelization method and equipment in a white space zone. Background technique [0002] Wireless Local Area Network (WLAN) technology standards are established through the IEEE 802.11 standards committee. IEEE 802.11a and 11b use unlicensed bands of 2.4.GHz and 5GHz to provide maximum data rates of 11Mbps and 54Mbps, respectively. IEEE802.11g adopts OFDM (Orthogonal Frequency Division Multiplexing) and provides a maximum data rate of 54 Mbps. IEEE 802.11n employs MIMO-OFDM and provides a maximum data rate of 300Mbps for 4 spatial streams. [0003] The IEEE 802 / 11af standard for defining the operation of unlicensed devices in the TV White Space (TVWS) band is currently under development. [0004] TVWS includes VHF (Very High Frequency) bands (54 to 60, 76 to 88 and 174 to 216MHz) and UHF (Ultra High Frequency) bands (470 to 698MHz) allocated for TV broadcas...
