## Abstract

A method of transmitting a White Space Map information in a wireless local area network system (WLAN) is disclosed. A method of transmitting a white space map information from a first station to a second station in a regulatory domain where a licensed device and an unlicensed device are permitted to operate together in a wireless local area network (WLAN) comprises acquiring a first list of available channels at each location of a plurality of locations from a regulatory database; determining a second list of available channels at a white space zone (WSZ) using the first list of available channels at each location of a plurality of locations; and transmitting, to the second station, one of a beacon frame, a probe response frame and a white space map announcement frame comprising a white space map (WSM) element, the WSM element including information of the WSZ and the second list of available channels, wherein the WSZ is a geographical area in which common available channels are set.

## Claims

### Claim 1

A method for transmitting a signal by a station (STA) in a wireless communication system, the method comprising:
transmitting a channel availability query including multiple device location information;
receiving a channel availability query response that includes a White Space Map (WSM); and
transmitting signal via one or more channels indicated by one or more channel numbers included in the WSM,
wherein the one or more channels is commonly used within a bounded area defined by the multiple device location information, and
wherein the device location information includes a value indicating latitude, a value indicating longitude, and a value indicating altitude.

### Claim 2 (depends on 1)

The method of claim 1, wherein the device location information consists of 3-dimensional (3D) information.

### Claim 3

A station (STA) transmitting a signal by a in a wireless communication system, the STA comprising:
a transceiver; and
a processor configured to:
transmit a channel availability query including multiple device location information;
receive a channel availability query response that includes a White Space Map (WSM); and
transmit a signal via one or more channels indicated by one or more channel numbers included in the WSM,
wherein the one or more channels is commonly used within a bounded area defined by the multiple device location information, and
wherein the device location information includes a value indicating latitude, a value indicating longitude, and a value indicating altitude.

### Claim 4 (depends on 3)

The STA of claim 3, wherein the device location information consists of 3 dimensional (3D) information.
