    摘要: Provided is a resource allocation method capable of improving a reception quality when connecting a plurality of sub frames into one frame and performing a communication process for each of the frames. In this method, when a sub frame #1 is transmitted, LRB is selected as a resource allocation format according to CQI fed back from a mobile station and RB having a preferable propagation quality is allocated for transmission data according to the LRB format. When a sub frame #2 is transmitted, the same resource allocation method (LRB) as the head sub frame is used and the transmission data is allocated for the same RB. When a sub frame #3 is transmitted, the resource allocation method is switched from the sub frame #1 and the sub frame #2 and the transmission data is allocated for RB by using the DRB format.

    摘要: A radio transmission apparatus performs communications with high transmission efficiency. In this apparatus, a modulator modulates data and outputs to a first spreader. A second modulator modulates data under a modulation scheme having a higher M-ary number than the first modulator and outputs the modulated data to a second spreader. The first spreader spreads the data and outputs the spread data to a frequency domain mapping section. The second spreader spreads the data and outputs the spread data to a time domain mapping section. A frequency domain mapping section maps chips with spread data on subcarriers in the frequency domain and outputs the data with chips mapped on subcarriers to an IFFT section. The time domain mapping section maps chips with spread data on subcarriers in the time domain and outputs the data with chips mapped on subcarriers to the IFFT section.

    摘要: Provided is a base station capable of performing cell search of all mobile stations having different communicable frequency band widths in a scalable band width communication system to which a multi-carrier communication method such as the OFDM method is applied. The base station includes: a modulation unit (102) for modulating SCH data after being encoded; a sub carrier setting unit (105) for setting one of the sub carriers to a sub carrier (SCH sub carrier) constituting the OFDM symbol for SCH data transmission; and an IFFT unit (106) for mapping the SCH data to the sub carrier set by the sub carrier setting unit (105) among the sub carriers and performing IFFT to generate an OFDM symbol. The sub carrier setting unit (105) sets one of the sub carriers which has a frequency of a common multiple between the sub carrier interval and the cell search interval as an SCH sub carrier.

    摘要: A pilot reception power measuring section measures reception power of a pilot symbol and a data section reception power prediction section predicts reception power of data symbols based on the reception power of the pilot symbol. A power comparison section calculates a difference between this predicted value and the actual reception power of the data symbol, and when the difference is large, a collision position detection section regards the data symbol at the hopping position as colliding with data symbols in other cells. Then, an error correcting decoding section carries out error correcting processing by reducing likelihood of the data symbols detected to be involved in the collision and can thereby improve the error rate characteristic of decoded data.

    摘要: A base station apparatus wherein the interference suppression symbol combination can be performed in a case of using the repetition technique in a multicarrier communication. In a base station (100), a repetition part (103) repeats or copies each of data symbols received from a modulating part (102) to create a plurality of same data symbols. A phase rotating part (106) imparts, in accordance with a phase rotation angle set by a setting part (107), phase rotations to the pilot and data symbols received from a multiplexing part (105). At this moment, the phase rotating part (106) imparts the phase rotations of the same angle to the pilot and data symbols assigned to the same subcarrier. Further, the phase rotating part (106) causes the phase rotation difference between the same data symbols in a cell to be different from the phase rotation difference between the same symbols in an adjacent cell.
