    摘要: An OFDM communication system which performs appropriate feedback flexibly adapted to channel states, while suppressing an amount of feedback information. The OFDM communication system has first and second communication apparatuses. In a second receiver of the second communication apparatus, a channel quality measurement part measures channel quality for each of sub-carriers. A time variation measurement part and a frequency measurement part respectively measure variation of channel quality in a time domain and a frequency domain, respectively, and output the variation of channel quality as time variation information and frequency variation information, also respectively. Based on the measured time variation information and frequency variation information, a two-dimensional control part performs two-dimensional blocking for forming two-dimensional blocks each from plural adjacent sub-carriers which are adjacent to each other in the time domain and the frequency domain. The two-dimensional control part measures and outputs channel quality of each two-dimensional block, as feedback information.

    摘要: An object of the present invention is to reduce the amount of calculation performed in a mobile station and amount of information exchanged between a base station and mobile station in a mobile communication system where the base station autonomously assigns a scramble code. In the mobile communication system, the base station starts communication by using a predetermined initialization scramble code used only at its activation time. The mobile station positioned in a cell determines whether the scramble code identified upon cell search time is the initialization scramble code. Only when the scramble code is the initialization scramble code, the mobile station determines a candidate scramble code, determines whether the candidate scramble code is usable in communication, and notifies the base station of the control information including the determination result. Based on the control information, the base station determines a service scramble code to be used, from the candidate scramble codes, and applies the service scramble code to start communication.

    摘要: A wireless communication apparatus is provided that is capable of achieving both the suppression of interference between base stations and the capability to track mobile stations that are moving at a high speed. A moving speed estimating unit estimates the moving speed of each mobile station based on reception signals. A directivity determining unit determines reception antenna directivity for each mobile station based on the reception signals and the estimated moving speeds. A signal separating unit separates the reception signals into signal components that have been transmitted from respective mobile stations, based on the directivities. A signal recovering unit recovers transmission signals from respective mobile stations based on the respective signal components. A resource assigning unit determines radio resource assignments of transmission signals to the respective mobile stations based on a service quality signal and the estimated moving speed. A transmission signal generating unit generates transmission signals based on transmission information, the directivities, and the resource assignments. A transmission signal multiplexes the transmission signals, using the resource assignment signals, and outputs the multiplexed transmission signal.

    摘要: A channel quality measurement method that accomplishes efficient channel quality measurement for each mobile station is presented. In a frequency band including a plurality of frequency blocks, a base station measures the channel quality of each of a plurality of mobile stations. With respect to each mobile station, when a pilot resource for demodulation is not allocated in at least one of the frequency blocks, the base station allocates a specific pilot resource for channel quality measurement in that frequency block. The channel quality of each mobile station in the plurality of frequency blocks is measured by using one or both of the pilot resource for demodulation and the dedicated pilot resource for channel quality measurement.

When a weighted absolute value signal sum obtained by multiplying the absolute weighted value signal sum by a shift factor determined on the basis of the received signal intensity is greater than all of preceding absolute response value signals as absolute response value signals higher in response speed than the precursor candidate signal set, n impulse response signals next in response speed to, the precursor response signal set are made to be a postcursor response signal set.
