    摘要: A method is provided for recognizing the frequency bandwidth of a base station in a mobile communication system with frequency bandwidth scalability where the transmission frequency bands of base stations and mobile stations having different frequency bandwidths are overlaid with one another. The base stations transmit to a mobile station first information, including information about their frequency bandwidths at the same frequency position over a minimum frequency bandwidth with the same center frequency. The mobile station recognizes the presence of the base stations by comparing the first information from the base stations and detects the frequency bandwidth information in the first information.

    摘要: Disclosed is a method for estimating a channel using a pilot signal in a wireless communication system based on multi-carrier multiple access. A transmission side generates a pilot symbol correlated with spread data symbols which is included in a spread symbol generated through a band spreading, inserts the pilot symbol into the spread symbol, and transmits the spread symbol. A reception side receives the spread symbol and detects the pilot signal by using the spread data symbols and pilot symbol included in the spread symbol. Therefore, it is possible to simultaneously obtain both the position optimization of a pilot symbol, according to a channel state such as a correlation band or correlation time (which is an advantage over the pilot-tone-based channel estimation method), and a noise reduction effect by the averaging procedure (which is an advantage over the pilot-channel-based channel estimation method), so that the accuracy of channel estimation can be improved.

The method includes, when a preamble scanning duration arrives, acquiring preamble information on at least one neighbor BS through preamble scanning. It is determined whether to scan a header for at least one neighbor BS among neighbor BSs for which the preamble information are acquired, in consideration of at least one of the acquisition or non-acquisition of new preamble information through the preamble scanning and a variation of an environment of a preamble acquired through the preamble scanning. And, in case that it is determined to scan the header, a header for a corresponding neighbor BS is scanned and header information of the neighbor BS is acquired.

    摘要: A method and apparatus for transmitting and receiving a signal in a wireless communication system. The wireless communication system includes a transmitter with at least four transmit antennas and a receiver with at least one receive antenna. Space Frequency Block Coding (SFBC) processes are performed for input signals on a basis of two antenna pairs. Signal blocks whose number corresponds to the number of transmit antennas are output. A Space Time Block Coding (STBC) process is performed for the signal blocks generated according to the antenna pairs. Signals carried by single carriers are transmitted through the at least four transmit antennas mapped to the signal blocks.
