Abstract  Abstract

The invention claims a terminal device which can control and reduce the interference between a plurality of pilot signal frequency sequence used by one terminal under the condition of using SU-MIMO and MU-MIMO at the same time. In the terminal device (200) the pilot frequency information determins unit (204) based on an assignment control information and determins at least one of the respective Walsh sequence of the first flow group and the second flow group comprising a plurality of flows a pilot signal generates unit (205) through using the determined reduction ratio in the Walsh sequence included in the first flow group and the second storage unit in the storage process forming the sending signal. At this time the mutually orthogonal Walsh sequence is set to the first flow group and the second flow group and the unit of allocating the user is flow group.

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.
