发明名称 INTERLEAVING IN OFDMA DATA TONE PLANS
摘要 Methods and techniques for interleaving orthogonal frequency division multiple access (OFDMA) data are disclosed. An apparatus includes an interleaver configured to interleave encoded data for at least one of a 72, 120, or 312 data tone allocation. The interleaver is further configured to generate a series of interleaved bits, for transmission based on the interleaved encoded data. The interleaver includes one or more stream interleavers corresponding to one or more spatial streams. The one or more stream interleavers are further configured to interleave the encoded data and generate the series of interleaved bits. The apparatus further includes a transmission circuit configured to transmit the series of interleaved bits via the one or more spatial streams.

主权项 1. An apparatus for wireless communication, comprising: an interleaver configured to interleave encoded data for at least one of a 72, 120, or 312 data tone allocation, and generate a series of interleaved bits for transmission based on the interleaved encoded data, the interleaver comprising one or more stream interleavers corresponding to one or more spatial streams, wherein the one or more stream interleavers are configured to interleave the encoded data and generate the series of interleaved bits by using: an interleaver depth of: 2, 3, 4, 6, 8, 9, 12, 18, 24, or 36 for the 72 data tone allocation;2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, or 60 for the 120 data tone allocation; or2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, or 156 for the 312 data tone allocation;an interleaved rotation index of at least one of [0, 2, 1, 3], [0, 4, 2, 6, 1, 5, 3, 7], or [0, 5, 2, 7, 3, 6, 1, 4]; anda base subcarrier rotation of: any integer within the inclusive range between 1 and 22 for the 72 data tone allocation;any integer within the inclusive range between 1 and 34 for the 120 data tone allocation; orany integer within the inclusive range between 1 and 82 for the 312 data tone allocation; and a transmission circuit configured to transmit the series of interleaved bits via the one or more spatial streams.
