Abstract:
An apparatus and method for allocating dedicated pilots for supporting MIMO and setting MIMO-only interlace slots in a CDMA 2000 Nx-EV-DO compatible system. The method includes determining whether a current interlace is a particular interlace in which a Multiple Input Multiple Output (MIMO) signal for channel estimation in a receiver is inserted; and inserting the MIMO signal into the particular interlace when the current interlace is the particular interlace and then transmitting the MIMO signal according to a predetermined transmission scheme. By the apparatus and method, it is possible to effectively use the MIMO in a system in which EV-DO users, MIMO EV-DO users, OFDM users, MIMO-OFDM users co-exist.
