Method and apparatus for performing a channel availability query for a plurality of locations

A station device operable as a first station (STA) of a channel query procedure in a wireless communication system, the station device comprising:

• a transceiver supporting the channel query procedure, and configured to:
• transmit a first message comprising device location information of one or more locations for the channel availability query to a second STA supporting the channel query procedure and corresponding to a channel availability responding STA of the channel query procedure;
• and
• receive a second message including channel availability information from the second STA;
• and
• a processor connected to the transceiver and configured to control the transceiver to operate the first STA as a channel availability query requesting STA of the channel query procedure,
• wherein, when the device location information of the first message is for multiple locations within an area and the second message indicates that the channel availability information is commonly applicable to the multiple locations, the channel availability information is commonly applicable to the multiple locations within the area, and
• wherein, when the device location information of the first message is for the multiple locations within the area and there is no channel availability information commonly applicable to the multiple locations, the channel availability information is applicable to the first location among the multiple locations.

A method for a station (STA) to perform a channel query procedure in a wireless communication system, the method comprising:

• receiving, from a first STA corresponding to a channel availability query requesting STA, a first message at a second STA supporting the channel availability query process, the second STA corresponding to a channel availability query responding STA, the first message comprising device location information of one or more locations for the channel availability query;
• and
• transmitting, to the first STA by the second STA, a second message comprising channel availability information,
• wherein, when the device location information of the first message is for multiple locations within an area and the second message indicates that the channel availability information is commonly applicable to the multiple locations, the channel availability information is commonly applicable to the multiple locations within the area, and
• wherein, when the device location information of the first message is for the multiple locations within an area and there is no channel availability information commonly applicable to the multiple locations, the channel availability information is applicable to a first location among the multiple locations.

A station device operable as a second station (STA) of a channel query procedure in a wireless communication system, the station device comprising:

• a transceiver configured to:
• receive a first message comprising device location information of one or more locations for a channel availability query from a first STA corresponding to a channel availability query requesting STA of the channel query procedure and
• transmit a second message comprising channel availability information to the first STA;
• and
• a processor connected to the transceiver, and configured to control the station device to support the channel query procedure and operate as a channel availability responding STA of the channel query procedure,
• wherein, when the device location information of the first message is for multiple locations within an area and the channel availability information is commonly applicable to multiple locations, the channel availability information is commonly applicable to the multiple locations within the area, and
• wherein, when the device location information of the first message is for the multiple locations within the area and there is no channel availability information commonly applicable to the multiple locations, the channel availability information is applicable to a first location among the multiple locations.
