Method and apparatus for dynamic station enablement procedure in a wireless local area network system
A method of dynamic station enablement procedure in a wireless local area network (WLAN) is disclosed. A method of performing an enablement procedure by a first 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 receiving, from a second station, an enabling signal including advertisement protocol element with an advertisement protocol identification (ID) field which indicates an advertisement protocol the second station supports; and exchanging DSE (dynamic station enablement) related messages with the second station using a GAS (generic advertisement service) protocol.
1. A method for a first station to operate in a TV White Space band, the method comprising:
receiving, from a second station, a message including an advertisement protocol element, the advertisement protocol element including an advertisement protocol ID indicating a specific protocol among multiple Generic Advertisement Service (GAS) protocols;
transmitting a query request message to the second station using the specific protocol when the specific protocol is a GAS protocol predefined to be used for acquiring information on available channel information within the TV White Space band; and
receiving a query response message comprising a WSM (White Space Map) using the specific protocol, the WSM comprising:
a channel number field comprising a list of available channels;
a type field indicating whether the list is a full channel list for all of the available channels or a partial channel list for a part of all the available channels; and
a version field indicating a Map version of the WSM,
wherein, when the first station receives multiple WSMs including the version field indicating the same Map version and including the type field indicating the partial channel list, the first station constructs the full channel list using the multiple WSMs, and
wherein the specific protocol comprises a Registered Location Query Protocol (RLQP).
2. The method of claim 1 , wherein:
the second station comprises an enabling station; and
the first station comprises a dependent station.
3. The method of claim 1 , wherein the WSM further comprises a maximum power field indicating maximum transmit powers on each of the available channels.
4. An apparatus operating in a TV White Space band as a first station, the apparatus comprising:
a transceiver configured to receive a message including an advertisement protocol element and a query response message comprising a WSM from a second station, the WSM comprising:
a channel number field comprising a list of available channels;
a type field indicating whether the list is a full channel list for all of the available channels or a partial channel list for a part of all the available channels; and
a version field indicating a Map version of the WSM; and
a processor connected to the transceiver,
wherein the advertisement protocol element includes an advertisement protocol ID indicating a specific protocol among multiple Generic Advertisement Service (GAS) protocols,
wherein the processor is configured to control the transceiver to transmit a query request message to the second station using the specific protocol when the specific protocol is a specific GAS protocol predefined to be used for acquiring information on available channel information within the TV White Space band,
wherein the query response message is received using the specific protocol,
wherein the processor is further configured to construct the full channel list when multiple WSMs having the version field indicating the same Map version and having the type field indicating the partial channel list are received by the transceiver, and
wherein the specific protocol comprises a Registered Location Query Protocol (RLQP).
5. The apparatus of claim 4 , wherein:
the first station comprises an dependent station; and
the second station comprises an enabling station.
6. The apparatus of claim 4 , wherein the WSM further comprises a maximum power field indicating maximum transmit powers on each of the available channels.
