A hybrid approach is provided to the formatting of signals for transmission in a high-data-rate wireless system. We retain the format and timing of an HRPD frame, but the data portions of selected slots within the frame are given over to OFDMA transmission instead of CDMA transmission. Because OFDMA is robust against self-interference, high throughput can be achieved in a greater number of slots, including at least some in which a low signal-to-interference-noise ratio (SINR) might limit a pure CDMA data rate.
