Method and Apparatus for Transmitting and Receiving a White Space Map Information in a Wireless Local Area Network System
First Claim
1. 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), the method comprising:
- obtaining, at the first station, a list of available channels with a first channel granularity and maximum allowed transmission powers of the available channels from a regulatory database; and
transmitting, from the first station, one of a beacon frame, a probe response frame and a white space map announcement frame comprising a white space map (WSM) element to the second station such that the second station operates as the unlicensed device using one or more channels having a second channel granularity and located only within the available channels identified by the WSM element,wherein the WSM element comprises a channel number field and a maximum power level field,wherein the channel number field indicates the list of available channels with the first channel granularity and the maximum power level field indicates maximum allowed transmission powers of the available channels.

Abstract
A method and an apparatus transmitting and receiving a White Space Map information between two stations in a wireless local area network system are disclosed. For 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 in a wireless local area network (WLAN), the method comprises: obtaining, at the first station, a list of available channels with a first channel granularity and maximum allowed transmission powers of the available channels from a regulatory database; and transmitting, from the first station, one of a beacon frame, a probe response frame and a white space map announcement frame comprising a white space map (WSM) element to the second station such that the second station operates as the unlicensed device using one or more channels having a second channel granularity and located only within the available channels identified by the WSM element, wherein the WSM element comprises a channel number field and a maximum power level field, wherein the channel number field indicates the list of available channels with the first channel granularity and the maximum power level field indicates maximum allowed transmission powers of the available channels.

15. An apparatus for transmitting a white space map information to a 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), the apparatus comprising:
-
a transceiver configured to transmit one of a beacon frame, a probe response frame and a white space map announcement frame to the station; and a processor configured to obtain a list of available channels with a first channel granularity and maximum allowed transmission powers of the available channels from a regulatory database, to generate one of the beacon frame, the probe response frame and the white space map announcement frame including a white space map (WSM) element, and to control the transceiver to transmit one of the beacon frame, the probe response frame and the white space map announcement frame comprising the WSM element to the station such that the station operates as the unlicensed device using one or more channels having a second channel granularity and located only within the available channels identified by the WSM element wherein the WSM element comprises a channel number field and a maximum power level field, wherein the channel number field indicates the list of available channels with the first channel granularity and the maximum power level field indicates maximum allowed transmission powers of the available channels. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
