Abstract  Abstract

The present invention relates to an apparatus and method for configuring a dedicated pilot allocation for MIMO support and a MIMO dedicated interlace slot in a CDMA 2000 Nx-EV-DO compatible system. A transmission method for transmitting packet data in a forward link of a system includes: checking whether a current interlace is a specific interlace into which a multiple input multiple output (MIMO) signal is inserted for channel estimation at a receiver; And inserting and transmitting the MIMO signal in the specific interlace according to a predetermined transmission scheme when the current interlace corresponds to the specific interlace. Accordingly, according to the present invention, MIMO dedicated pilot / pilot tones for multiple antennas are transmitted in a specific MIMO interlace, and thus, MIMO can be effectively used in a system in which EV-DO, MIMO-EV-DO, OFDM, or MIMO-OFDM users coexist. Can be.
