Abstract  Abstract

PROBLEM TO BE SOLVED: To disclose a terminal device capable of reducing interference between sequences in a pilot signal between terminals while suppressing interference between sequence low in a plurality of pilot signals used by the same terminal even when simultaneously applying SU-MIMO and MU-MIMO.

SOLUTION: In a terminal device 200 a pilot information determination section 204 determines a Walsh sequence of each of first and second stream groups where at least one group includes a plurality of streams on the basis of assignment control information and a pilot signal generation section 205 diffuses the streams included in the first and second stream groups according to the determined Walsh sequence thereby forming a transmission signal. At such a time Walsh sequences which are orthogonal to each other are set to the first and second stream groups and a user is assigned for the unit of a stream group.
