PROBLEM TO BE SOLVED: To provide a hybrid method for formatting of a signal for transmission, in a high data rate radio system. SOLUTION: While the format and timing of a HRPD frame are maintained, the data portion of a selected slot in the frame is given via OFDMA transmission, rather than CDMA transmission. Since OFDMA is robust with respect to self interference, low SINR (Signal-to-Interference-Noise Ratio) may limit pure CDMA data rate. High throughput is achieved with more slots, including at least several slots. COPYRIGHT: (C)2006,JPO&NCIPI |
