A device and method for performing Internet Protocol (IP) configuration by a station (STA) of a wireless communication network. The method includes: prior to associating with an access point (AP), receiving, at the STA from the AP, a beacon frame including subnet information and IP type information of the AP; transmitting, by the STA to the AP, a request frame including a requested IP address. Here, the requested IP address is determined by the STA based on the subnet information and the IP type information of the AP. The method also includes: receiving, by the STA from the AP, a response frame including information on an availability of the requested IP address; and associating with the AP by the STA based on the response frame.

The present invention relates to a method for a first station (STA) comprising: obtaining available channel information by accessing a database that manages the available channel information within the white space band, and transmitting a white space map (WSM) generated according to the available channel information to a second STA, the WSM includes a channel map field having a variable length, a length field including the length of the channel map field, and map ID information indicating a type of the WSM and whether the WSM being updated; and if the available channel information obtained from the DB indicates that no available channel exists within the white space band, a map ID is set to indicate that the WSM is the updated WSM, and the first STA transmits the WSM which is set as the length field to indicate that the length of the channel map field is 0.
摘要:
When channel switching to a channel in a white space band is performed through tunneled direct link setup (TDLS) in a wireless local area network (WLAN) system, it is confirmed whether or not a white space band between STAs is operable by directly including white space band performance between communication target STAs and device identifier information in a TDLS request/response message. Thus, one STA performs a channel availability query (CAQ) procedure in order to obtain available channel information, and a TDLS channel switching request/response message is exchanged by selecting a target channel in an available channel. Therefore, TDLS-based channel switching to a white space band is efficiently performed.

A method for an enabler entity to indicate an event to a manager entity includes transmitting, from the enabler entity to the manager entity, an event indication message indicating an event in a device served by the enabler entity. The enabler entity enables communication between the device and the manager entity and the manager entity exchanges information required for coexistence between enabler entities comprising the enabler entity. The event indication message includes type information indicating that the event indication message is for indicating that a specific device is detected by the device, the specific device operating on a frequency not permitted to the specific device.

A method for receiving a measurement report includes: transmitting, by an apparatus including a coexistence manager (CM), a measurement request message for acquiring a measurement report from at least one device that uses a channel in a TV band to a coexistence enabler (CE); and receiving, by the apparatus, a measurement response message including the result of the measurement results from the CE. The measurement request message includes a first element indicating which of a primary detection, a detection of a device that uses the TV band, and a channel load measurement is requested. The measurement request message includes at least one of a start frequency, an end frequency, a channel list, and a measurement time related to the measurement, and the measurement report includes at least one selected from among the result of primary detection, the result of the detection of the device that uses the TV band.
摘要:
In a method of receiving one or more resources, an apparatus having a coexistence enabler entity transmits a request message containing information on one or more devices using channels within a TV band to a coexistence manager. Here, the information contains an available channel list obtained from the one or more devices using the channels within the TV band, and the request message further contains one or more of maximum power level, channel load and location information. In the method, the apparatus receives a response message for allocating the resources from the coexistence manager. Here, the response message further contains one or more of information on channel numbers, start frequency, end frequency and maximum power level.
