    Abstract: Systems and methods are described herein that allow information carrying bits of a transmission block to be placed at higher-reliability positions prior to transmission. An exemplary method includes generating a set of payload bits to be encoded for transmission, wherein the set of payload bits includes at least one known bit, interleaving the set of payload bits to generate an interleaved set of payload bits, wherein the interleaved set includes the at least one known bit in a predetermined position in the interleaved set, providing the interleaved set to a cyclic redundancy check (CRC) encoder to generate CRC-interleaved set of payload bits, wherein the CRC-interleaved set includes the at least one known bit in a predetermined position within the CRC-interleaved set, and encoding the CRC-interleaved set for transmission to a wireless device. Associated network nodes and wireless devices are included.

    Abstract: A first communication device generates a physical layer (PHY) preamble of a PHY data unit. A signal field of the PHY preamble includes i) a common block of information bits having information for multiple second communication devices and ii) a plurality of user blocks of information bits, each user block having information for a respective one of the multiple second communication devices. The common block includes a frequency resource unit allocation field that defines a plurality of frequency resource units corresponding to a PHY payload of the PHY data unit. The user blocks respectively correspond to frequency resource units defined by the frequency resource unit allocation field. Each user block includes an indication of a modulation and coding scheme (MCS) used in the corresponding frequency resource unit. Each group of two user blocks is encoded as a respective second encoded block to allow the multiple second communication devices to efficiently decode the signal field.

    Abstract: A shaping encoder configured to generate a stream of output bit-words, wherein different bit-word values have different respective rates of occurrence to cause the optical transmitter connected to the shaping encoder to transmit constellation symbols of relatively high energy less frequently than constellation symbols of relatively low energy. The stream of output bit-words is self-referencing in that it encodes one of the input bitstreams applied to the shaping encoder in one or more designated bits of the output bit-words and is generated using a dither stream that can be recovered by the shaping decoder solely based on those one or more designated bits. As a result, some of the circuitry used in the shaping encoder at the transmitter and in the shaping decoder at the receiver can be identical, which can advantageously be used, e.g., to reduce the production costs.
