20140023014 | METHOD FOR CHANNEL SWITCHING IN WIRELESS PERSONAL AREA NETWORK AND APPARATUS FOR SAME - A method for a user equipment switching an operation channel in a wireless personal area network (WPAN), disclosed in the present invention, comprises the following steps: setting a PAN coordinator and an association for a first frequency band; receiving from the PAN coordinator of the first frequency band information for channel switching to a second frequency band; and setting the PAN coordinator and the association for the second frequency band based on the switching information that is received. | 01-23-2014 |
20140024404 | Method of Initializing a Channel in a Medical Body Area Network - According to the disclosure of the present invention, a method of a Network Body Area Network (MBAN) master to control the channel defaulting of an MBAN terminal in an MBAN system is provided. The method includes: performing an association process with the MBAN terminal through a channel of a first frequency band; and transmitting control information for the channel initialization of the MBAN terminal to the MBAN terminal. The control information includes a channel defaulting timer, and a value of the channel defaulting timer indicates a time between the timing when the MBAN terminal cannot receive a signal from a channel of the first frequency band in use and the timing when the channel search of a second frequency band starts. | 01-23-2014 |
20140036863 | Channel Switching Method in a Medical Body Area Network - The disclosure of the present invention provides a method for a Medical Body Area Network (MBAN) to control, through a master, the channel switching of an MBAN terminal that uses a channel of a first frequency band in an MBAN system. The method includes: receiving information related to the use of each channel of a second frequency band from an MBAN controller; and transmitting information on a channel of the second frequency band that the MBAN terminal is to switch on the basis of the received information related to the use of each channel of the second frequency band. The first frequency band and the second frequency band are distinguished from each other based on whether the MBAN terminal uses a corresponding frequency band first. | 02-06-2014 |
20140314032 | Method and Apparatus for Transmitting and Receiving a Whitespace Map in a Wireless Communication System - The present invention relates to a wireless communication system, and more specifically, to a method and apparatus for transmitting and receiving a whitespace map. The method for transmitting whitespace map (WSM) information from a first station (STA) to a second STA includes the steps of: setting a map version bit value included in the WSM information as a predetermined value; and transmitting the WSM information including the predetermined map version bit value to the second STA. | 10-23-2014 |
20140376474 | METHOD FOR SETTING OPERATING CHANNEL IN WHITE SPACE BAND AND DEVICE THEREFOR - Disclosed are a method for setting an operating channel in a white space band and a device therefor. Particularly, a method for enabling a first device to set an operating channel in a white space band comprises the steps of: acquiring information on an available TV channel from a geo-location database; and setting an operating channel on the basis of the information on the available TV channel, wherein a center frequency of the operating channel can be set differently according to a TV channel used by an incumbent device among TV channels adjacent to the TV channel on which the operating channel is set. | 12-25-2014 |
20150043338 | Method for Selecting a Master CM in a Coexistence Network - The present invention relates to a method for requesting the selection of a master management apparatus through a server by a management apparatus enabling television white space (TVWS) apparatuses to coexist in a TVWS. The method includes the steps of: determining whether the trigger condition of the process for selecting the master management apparatus is satisfied; and requesting the selection of the master management apparatus by the server, wherein the master management apparatus is configured to determine a channel selection in the TVWS for terminals connected to the master management apparatus and a slave management apparatus, and the trigger condition can be based on the load balance parameters or geographical coverage parameters of the management apparatus. | 02-12-2015 |
20150063332 | METHOD FOR SETTING OPERATING CHANNEL IN WHITE SPACE BAND AND DEVICE THEREFOR - A method for setting an operating channel in a white space band and a device therefore are disclosed. Specifically, a method for setting an operating channel in a white space band by a device comprises the following steps: receiving a white space map including information on a an available TV channel and an offset value in the available TV channel; and setting an operating channel on the basis of the information on the available TV channel and the offset value in the available TV channel, wherein the offset value indicates a shift amount of the center frequency of the operating channel from the center frequency of the available TV channel. | 03-05-2015 |
20150078287 | METHOD AND APPARATUS FOR DETERMINING OPERATING CHANNEL IN WIRELESS COMMUNICATION SYSTEM - The present invention relates to a wireless communication system and, more specifically, to a method and an apparatus for determining an operating channel. The method for determining the operating channel of a station (STA) in a TV whitespace (TVWS) wireless LAN system, according to one embodiment of the present invention, comprises the steps of: receiving information on an index which indicates an operating class including channel start frequency, channel spacing, and channel set parameters; and determining a main frequency of the operating channel on the basis of the parameters indicated by the index of the operating class. The main frequency of the operating channel can be determined on the basis of a correction value which is set differently according to the configuration of a basic channel unit of the operating channel. | 03-19-2015 |
