摘要： This invention relates to a transmitter apparatus, a receiver apparatus, a transmission method and a notification method that, when a switching between MIMO communication and non-MIMO communication is performed, can suppress the increase of an SRS (Sounding Reference Signal) resource, while suppressing the degradation of trackability of temporal variation of a channel. In a terminal (200), a mapping unit (212) maps an SRS sequence, which is received from a pilot, generating unit (216), on the basis of information related to an SRS hopping pattern, received from a base station (100). For this SRS hopping pattern, the frequency of the SRS transmissions via a first one of a plurality of antennas of the terminal (200) is higher than that of the SRS transmissions via a second one of the plurality of antennas of the terminal (200).

摘要： A wireless communication base station apparatus which is able to prevent deterioration in the throughput of LTE terminals even when LTE terminals and LTE+ terminals coexist. In this apparatus, based on the mapping pattern of the reference signals used only in LTE+ terminals, a setting unit (105) sets, in each subframe, the resource block groups where the reference signals used only by the LTE+ terminals are mapped. For symbols mapped to the antennas (110-1 to 110-4), an mapping unit (106) maps, to all the resource blocks within one frame, cell specific reference signals used for both LTE terminals and LTE+ terminals. For the symbols mapped to the antennas (110-5 to 110-8), the mapping unit (106) maps, to the plurality of resource blocks, of which part of the resource block groups is comprised, in the same subframe within one frame, the cell specific reference signals used only for LTE+ terminals, based on the setting results inputted from the setting unit (105).

摘要： Provided are a wireless communication apparatus and a reference signal generating method, wherein inter-cell interference is reduced inside and outside a CoMP set. A CoMP mode setting unit (101) sets whether the terminal (100) thereof is a CoMP terminal or a Non-CoMP terminal.

摘要： A wireless communication base station apparatus wherein when a frequency scheduling transmission and a frequency diversity transmission are performed in a multicarrier communication at the same time, the adaptive control of a channel for performing the frequency scheduling transmission can be prevented from being complicated. In this apparatus, a modulating part modulates an encoded Dch data to generate Dch data symbols. A modulating part modulates an encoded Lch data to generate Lch data symbols. An assigning part assigns the Dch and Lch data symbols to subcarriers constituting OFDM symbols and outputs them to a multiplexing part. At this moment, the assigning part assigns a set of Dch and Lch data symbols to each subcarrier for a respective subband.
