PROBLEM TO BE SOLVED: To provide an allocation method with which interference suppression effects can be obtained by combining received pilot blocks in the case where a sequence such as a CAZAC sequence is used as a pilot sequence.SOLUTION: According to the present invention, 2K pieces of pilot sequences are divided into K pieces of sets like {[C_1, C_2], [C_3, C_4], ..., [C_(2K-1), C_2K]}. One set of pilot sequences is allocated to cells #1 to #K. For example, the pilot sequence {C_1, C_2} is allocated to pilot blocks (SB#1, #2) of the cell #1, the pilot sequence {C_3, C_4} is allocated to pilot blocks (SB#1, #2) of the cell #2, the pilot sequence {C_5, C_6} is allocated to pilot blocks (SB#1, #2) of the cell #3, and the pilot sequence {C_7, C_8} is allocated to pilot blocks (SB#1, #2) of the cell #4. |
