摘要： A link adaptation method and others wherein feedback information amount can be reduced. According to this method, a receiving apparatus (100) calculates, based on a channel matrix, a capacity (C) and a stream ratio (r) that is a ratio of the reception qualities of streams, and then transmits, as feedback information, the calculated capacity (C) and stream ratio (r) to a transmitting apparatus. In the transmitting apparatus (200), the number of transmittable streams, the modulation scheme and the fed-back capacity (C) are used to calculate the encoding ratio (R) and sequence length (S) of spatial multiplexed symbols. Then, the modulation scheme (M1-Mn) of each stream is decided based on the fed-back stream ratio (r) and the sequence length (S) of spatial multiplexed symbols.

摘要： A multicarrier communication apparatus and the like wherein the arithmetic amount required for calculating a reception weight by which a multicarrier signal is to be multiplied is suppressed, while the reception characteristic for the multicarrier signal is improved. In the apparatus, a subcarrier transmission weight generating part (513) generates a transmission weight of each subcarrier, based on channel information of each subcarrier received from a channel information generating part (511) and a reception weight of each subcarrier group received from a subcarrier group reception weight generating part (512). The subcarrier transmission weight generating part (513) inputs the generated transmission weights of the respective subcarriers to the corresponding ones of multipliers (522).

摘要： There are disclosed a multiantenna radio transmitting apparatus and others wherein control information can be transmitted with enhanced reliability while overheads of transport signals being reduced. This apparatus uses a transmission antenna (Tx) (119) to SDM transmit transport data (1) (CW1) and also uses a transmission antenna (120) to SDM transmit transport data (2) (CW2). In this apparatus, when the transmission quality of the transmission antenna (Tx) (119) is better than that of the transmission antenna (Tx) (120), the control information (2) related to the transport data (2) (CW2) is transmitted in a space division multiplex mode via the transmission antenna (Tx) (119), while the control information (1) related to the transport data (1) (CW1) is transmitted in a diversity mode.

摘要： Provided are a radio communication terminal and a radio communication base station device which are installed in a Multi-User MIMO system even if the ability to suppress interference is low. According to beam combination information fed back from NON-MIMO UE, and beam information and a CQI fed back from another MIMO UE, a scheduler section (102) allocates a space resource to the NON-MIMO UE and allocates the remaining resource to the another MIMO UE. According to the beam combination information, a beam weight generating section (104) generates weight. A transmission beam forming section (105) multiplies each stream outputted from modulation sections (103-1, 103-2) by the weight to form a transmission beam.
