摘要： A system including a direct current tone, guard tone, data tone allocation, mapping, and inverse Fourier transform (IFT) modules. The direct current tone module determines a number of direct current tones based on whether a network device is operating in a single user or multi-user mode. The guard tone module determines a number of guard tones based on whether the network device is operating in the single user or multi-user mode. The data tone allocation module determines a number of data tones based on the number of direct current and guard tones. The mapping module receives data and based on the number of data tones, maps the data to the data tones. The IFT module performs a frequency to time domain conversion of an output of the mapping module to generate orthogonal frequency division multiplexing (OFDM) symbols during the single user mode and OFDM access symbols during the multi-user mode.

摘要： Disclosed is a wireless communication base station apparatus whereby it is possible to prevent degradation of throughput of LTE terminals, even when LTE terminals and LTE+ terminals are present together. In this apparatus, a setting section (105) sets in each subframe a resource block in which is arranged a reference signal that is employed solely by LTE+ terminals, based on the pattern of arrangement of reference signals employed solely by LTE+ terminals. In the case of symbols that are mapped to antennas (110-1) to (110-4), an arrangement section (106) arranges the characteristic cell reference signals employed by both LTE terminals and LTE+ terminals in all of the resource blocks in a single frame. In contrast, in the case of the symbols that are mapped to the antennas (110-5) to (110-8), the arrangement section (106) arranges in some of the resource blocks, that are set in accordance with the setting results input from a setting section (105), the characteristic cell reference signals that are employed solely by the LTE+ terminals.

摘要： A terminal apparatus is disclosed wherein even in a case of applying SU-MIMO and MU-MIMO at the same time, the inter-sequence interference in a plurality of pilot signals used by the same terminal can be suppressed to a low value, while the inter-sequence interference in pilot signal between terminals can be reduced. In this terminal apparatus (200): a pilot information deciding unit (204) decides, based on allocation control information, Walsh sequences of the respective ones of first and second stream groups at least one of which includes a plurality of streams; and a pilot signal generating unit (205) forms a transport signal by using the decided Walsh sequences to spread the streams included in the first and second stream groups. During this, Walsh sequences orthogonal to each other are established in the first and second stream groups, and users are allocated on a stream group-by-stream group basis.
