TRANSMISSION/RECEPTION APPARATUS AND METHOD FOR SUPPORTING BOTH HIGH RATE PACKET DATA TRANSMISSION AND ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING TRANSMISSION IN A MOBILE COMMUNICATION SYSTEM

摘要

A transmission apparatus for transmitting packet data in a forward link of a High Rate Packet Data (HRPD) system is disclosed. The apparatus includes a first transmission processor for modulating physical link packet data according to an Orthogonal Frequency Division Multiplexing (OFDM) transmission scheme; a second transmission processor for modulating the physical link packet data according to a Evolution Data Only (EV-DO) transmission scheme; an HRPD-compatible processor for generating a transmission signal based on a slot structure of the HRPD system using one of output signals of the first and second transmission processors, and transmitting the transmission signal to a wireless network; and a controller for controlling transmission of the transmission signal according to a selected one of the OFDM transmission scheme and the EV-DO transmission scheme.
