Abstract
The present invention relates to a wireless communication system, and more particularly, to a method and apparatus for transceiving channel availability query and response in a wireless communication system. According to the present invention, a scheme is provided to enable devices which operate in TVWS to request/response information on an available channel in a plurality of geographical locations in a more accurate and efficient manner.
Claims10
A method for performing channel availability query using a Generic Advertisement Service (GAS) protocol by a requester station (STA) in a wireless communication system, the method comprising:
- transmitting a GAS query request including a Registered Location Query Protocol (RLQP) element, comprising a first information ID field and a location information field, to a responder STA, the location information field comprising information on a plurality of locations of the requester STA;
- and
- receiving a GAS query response comprising a RLQP element, comprising a second information ID field and a White Space Map (WSM) information field, from the responder STA, the first information ID field and the second information ID field each comprising a value corresponding to a Channel Availability Query (CAQ), the WSM information field comprising a WSM information applicable for any location within the bounded area defined by the plurality of locations.
A requester station (STA) adapted to perform channel availability query using a Generic Advertisement Service (GAS) protocol in a wireless communication system, the station comprising:
- a processor configured to generate a GAS query request comprising a Registered Location Query Protocol (RLQP) element, comprising a first information ID field and a location information field, the location information field comprising information on a plurality of locations of the requester STA;
- and
- a transceiver configured to:
- transmit the generated GAS query request to a responder STA;
- and
- receive a GAS query response comprising a RLQP element, comprising a second information ID field and a White Space Map (WSM) information field, from the responder STA, the first information ID field and the second information ID field each comprising a value corresponding to a Channel Availability Query (CAQ), the WSM information field comprising a WSM information applicable for any location within the bounded area defined by the plurality of locations.
