摘要： Provided are a system and method for providing a wireless network service to a user terminal free of charge, by providing a doorway page for exposing an advertisement on the user terminal provided with the wireless network service through an access point. Accordingly, the user terminal may be provided with the wireless network service free of charge, other than the cost of viewing the advertisement exposed on the doorway page. An advertiser and a proprietor may expose the advertisement at the cost of providing the free wireless network service.

摘要： The present invention provides a method of a node sending frames in a Cognitive Radio (CR) system. The method of the node includes being allocated a first channel as an operating channel where the node will be operated, sensing one or more candidate channels available as the operating channel of the node, determining whether to extend a frequency bandwidth of the operating channel, in addition to the first channel, based on a result of the sense for the one or more candidate channels, and sending the frames using a frequency bandwidth extended by adding a second channel, newly determined as the operating channel, to the first channel according to the determination.

摘要： A method and an apparatus for a transmitter to transmit data in a wireless communication system are provided. This method includes: generating a first signal field including at least one symbol; generating a second signal field configured by repeating at least one symbol of the first signal field; and transmitting a frame including the first signal field, the second signal field, and a data field and a first symbol of the second signal field is modulated through binary phase shift keying (BPSK) and symbols from a second symbol of the second signal field are modulated through Q-BPSK. According to the present invention, a service filed can be extended while maintaining compatibility with a wireless communication system in the related art by transmitting a frame using symbol repetition.
