Figure 1

Illustration of B-IFDMA using subcarriers and OFDM symbols per subcarrier block within a time-frequency resource denoted as chunk. SC-FDMA with localized mapping (LFDMA) and SC-FDMA with distributed mapping (IFDMA) are shown for comparison. In B-IFDMA, high rate users are allocated more blocks within the chunks in either the time or the frequency direction. (A similar illustration is included in [12].)
