The present invention provides a method for allocating a pilot sequence that can obtain effect of reducing interference by combining received pilot blocks when sequence such as the CAZAC sequence as a pilot sequence is used. In the present invention, the pilot sequences by the number of 2K are divided into K sets of {C_1, C_2}, {C_3, C_4}, ..., {C_(2K-1), C_2K} and allocated a set of the pilot sequences to each of the cells #1 to #K. For example, pilot sequences: {C_1, C_2} are allocated to pilot blocks (SB #1, #2) of the cell #1, pilot sequences: {C_3, C_4} are allocated to pilot blocks (SB #1, #2) of the cell #2, pilot sequences :{C_5, C_6} are allocated to pilot blocks (SB #1, #2) of the cell #3, and pilot sequences {C_7, C_8} are allocated to two pilot blocks (SB #1, #2) of the cell #4.( Fig. 3 ) |
