摘要： A method for providing a single-frequency network (SFN) service between a base station (BS) and a mobile station (MS) in a wireless communication system. The BS sets a first segment indicator in a medium access control (MAC) message field before transmission, if a resource allocation scheme corresponds to general data transmission. The BS sets a second segment indicator in the MAC message before transmission, if the resource allocation scheme corresponds to single frequency-based data transmission. The MS receives the MAC message from the BS, and performs renumbering according to the first segment indicator or the second segment indicator included in the received MAC message.

摘要： Provided is an apparatus and method for simultaneously receiving data signals of two adjacent frequency allocation (FA) in a cellular environment. When there is another base station using an adjacent FA to an FA of the base station, a subcarrier mapper maps control information to subcarriers of predetermined sections such that a mobile station simultaneously receives data signals of the adjacent FAs. An inverse fast Fourier transform (IFFT) processor IFFT-processes data mapped to the subcarriers. Because two different BSs transmit the same data through independent paths, the mobile station can obtain a macro diversity gain. Also, it is possible to balance the loads of the two BSs.

摘要： Provided is a channel estimation apparatus and method in a broadband wireless communications system using a smart antenna are provided. In the channel estimation apparatus, an FFT processor converts a received time-domain signal into a frequency-domain signal by FFT-processing the received time-domain signal. A channel acquirer estimates a first channel information for an SDMA user using a preamble signal allocated to the SDMA user in the frequency-domain signal. A channel tracker estimates a second channel information for the SDMA user using pilots in a data area allocated to the SDMA user in the frequency-domain signal. A channel estimator estimates a final channel information by weighting the first channel information and the second channel information according to a channel change rate.
