1. A station (STA) for implementing spatial processing using stream-dependent modulation and coding schemes (MCSs), the station comprising:

  • at least one receive antenna; and

    a processor configured to at least;

    receive a first data stream and a second data stream via the at least one receive antenna, wherein the first data stream and the second data stream are space time block coding (STBC) processed;

    receive a third data stream via the at least one receive antenna, wherein the received third data stream is not STBC processed; and

    perform spatial decoding on the received first data stream to generate a first spatially decoded data stream and perform spatial decoding on the received second data stream to generate a second spatially decoded data stream;

    perform spatial decoding on the received third data stream to generate a third decoded data stream, wherein spatial decoding performed on the first data stream or the second data stream is based on a first modulation scheme, and wherein the spatial decoding performed on the third data stream is based on a second modulation scheme, and wherein the first modulation scheme is different than the second modulation scheme, wherein the first modulation scheme and the second modulation scheme are stream-dependent, and wherein the first modulation scheme and the second modulation scheme are based on a selected MCS.
