    • Systems and methodologies are described that facilitate employing circular buffer based rate matching. Encoded block(s) that include systematic, parity 1, and parity 2 bits can be generated using turbo code. Bit type can be identified to separate bits into distinct groups. Systematic bits can be interleaved together to generate a randomized sequence of systematic bits, parity 1 bits can be interleaved together to yield a randomized sequence of parity 1 bits, and parity 2 bits can be interleaved together to output a randomized sequence of parity 2 bits. The randomized sequences of parity 1 bits and parity 2 bits can be interlaced together in an alternating manner. The randomized sequence of systematic bits can be inserted into a circular buffer, and upon inserting the entire sequence, the interlaced parity bits can be inserted into the circular buffer (e.g., until reaching capacity). Bits inserted into the circular buffer are transmitted.

    • Techniques for performing codeword level scrambling for a MIMO transmission are described. A transmitter station may perform channel encoding for multiple data streams being sent simultaneously for a MIMO transmission. The channel encoding may include forward error correction (FEC) encoding and/or rate matching. The transmitter station may perform scrambling for the multiple data streams with different scrambling codes after the channel encoding. The transmitter station may also perform channel interleaving, symbol mapping, and spatial processing for the multiple data streams after the channel encoding. A receiver station may receive the MIMO transmission, perform descrambling for the multiple data streams with the different scrambling codes, and then perform channel decoding for the multiple data streams. The scrambling may allow the receiver station to isolate each data stream by performing the complementary descrambling and to obtain randomized interference from the remaining data stream(s), which may improve performance.
    • 描述了用于执行MIMO传输的码字级加扰的技术。 发射机站可以针对MIMO传输同时发送的多个数据流执行信道编码。 信道编码可以包括前向纠错(FEC)编码和/或速率匹配。 在信道编码之后,发射机站可以对具有不同扰码的多个数据流执行加扰。 在信道编码之后,发射台还可以对多个数据流执行信道交织,符号映射和空间处理。 接收站可以接收MIMO传输,用不同的扰码对多个数据流执行解扰,然后对多个数据流执行信道解码。 加扰可以允许接收机站通过执行补充解扰来隔离每个数据流,并从剩余的数据流获得随机化的干扰,这可以提高性能。
