A method and apparatus for providing orthogonal spot beams (14a, 14b), sectors (16a, 16b), and picocells (18). The transmissions can be made orthogonal by using orthogonal auxiliary pilots and different Walsh traffic channels in adjacent areas. In accordance with the IS-95 standard, the pilot signal is covered with the 64-chip Walsh sequence zero. The 64-chip all zeros Walsh sequence can be designated as P and the 64-chip all one sequence can be designated as M. In the present invention, additional pilot signals can be provided by concatenating 64-chip all zeros P and all ones M sequences. Thus, for two pilot signals, pilot Walsh sequences of PP and PM can be used. For four pilot signals, pilot Walsh sequences of PPPP, PMPM, PPMM, and PMMP can be used. The present invention can be extended such that any required number of pilot Walsh sequences can be generated by substituting each bit in an K-bit Walsh sequence with the 64-chip all zeros P or all ones M sequence depending on the value of that bit.
