Abstract: A channel information feedback device in a multi-antenna system and a method thereof are provided to reduce the amount of fed back channel information. A channel estimator(307) estimates a channel by using signals received through antennas. A code selector(309) selects codes for an Eigen vector corresponding to the channel information estimated by the channel estimator from a code book for expressing the channel information. A feedback controller(313) constructs a set of codes which are orthogonal to the codes selected by the code selector, and then controls so that the codes expressed as the amount of information can be fed back.

Abstract: A method and an apparatus for controlling transmission power in a mobile communication system based on fractional frequency reuse are provided to grasp a downlink interference degree of a terminal and control the maximum transmission power of a corresponding limit band, thereby increasing efficiency of using resources. Received signal strength indication(RSSI) information are received from corresponding adjacent base stations with regard to at least one assigned limit band(600,602). A backoff value of transmission power about the limit bands is calculated with reference to the RSSI information(610). Transmission power is determined by using a difference between the backoff value of the transmission power about the limit bands and the maximum transmission power(612).

Abstract: An apparatus and a method for acquiring an IP address in an MS(Mobile Station) which executes multi-FA(Frequency Allocation) communication in a broadband wireless communication system are provided to operate a single MS through a single IP address while operating each FA independently through a plurality of MAC(Media Access Control) addresses by establishing a basic MAC address in multi-FA access. An MS, which performs multi-FA communication in a broadband wireless communication system, comprises a driver(460), an MAC interface part(470), and an IP address management part(480). When the MS is initialized, the driver loads one among many MAC addresses for multi-FA access as a basic MAC address. The MAC interface part registers the loaded MAC address so as to be used at the upper layer of a MAC layer. If network entry is completed for at least one FA, the IP address management part acquires an IP address with the registered IP address.

Abstract: A method and a system for transmitting and receiving signals in a communication system are provided to minimize an increase in overheads and to extract band AMC(Adaptive Modulation and Coding) subchannel location/size information regardless of the ratio of multiple subchannel domains which are changed by a frame. In consideration of the CQI(Channel Quality Information) received from a mobile station, a base station allocates a portion of a frame as a band AMC subchannel domain and the other portion as a diversity subchannel domain(211). The base station allocates a MAP domain containing a MAP header part and a MAP body part in the diversity subchannel domain(213). The base station creates band AMC setup information, or information about the location and size of the band AMC subchannel domain, and maps the created band AMC setup information to the MAP header part(215). The base station maps all the diversity subchannel domain but the MAP domain with arbitrary data in the band AMC subchannel domain, creates a frame, and transmits the created frame to the mobile station in an FDM(Frequency Division Multiplexing) scheme(217).

Abstract: An apparatus and a method for dynamically allocating channels in a multichannel wireless communication system are provided to use a frame structure, where a band AMC(Adaptive Modulation and Coding) channel and diversity channels exist together at an identical time domain, by announcing channel distribution information through a MAP heading field. A base station in a multichannel wireless communication system comprises a scheduler(801), a message creator(805), and a subcarrier mapper(817). The scheduler classifies resources to be used for a band AMC channel, the first diversity channel, and the second diversity channel. The message creator creates a MAP heading field which contains physical distribution information for the band AMC channel and the first and second diversity channels. The subcarrier mapper maps the MAP heading field to a preappointed physical resource area. The MAP heading field includes bitmap information, channel-by-channel bit values enumerated in the order of frequency bands.
