Abstract: Techniques are provided for transmitting and receiving a mother code in an incremental redundancy hybrid automatic repeat-request protocol. A set of information bits corresponding to a message may be encoded and interleaved to produce the mother code. Each bit position of the mother code may be mapped to an output symbol, and each output symbol may be mapped to an antenna for transmission. One or more transmissions of symbols contained in the output symbols may be performed, where each transmission may include puncturing the mother code by selecting one or more symbols from the of output symbols, and transmitting each symbol in the one or more symbols on an antenna corresponding to that symbol. The mother code may be decoded, in part, by determining combinable bits contained within a set of received symbols, and computing one or more log-likelihood ratio values corresponding to each symbol in the set of received symbols.

Abstract: A first communication device determines assignment of at least a first orthogonal frequency division multiplex (OFDM) tone block and a second OFDM tone block for communication with a second communication device in a wireless local area network (WLAN). The first OFDM tone block is separated from the second OFDM tone block by a gap in frequency. The first communication device generates a physical layer (PHY) data unit for transmission to the second communication device, including generating a data portion of the PHY data unit that spans the first OFDM tone block and the second OFDM tone block. The first communication device transmits the PHY data unit to the second communication device via the first OFDM tone block and the second OFDM tone block such that no data is transmitted in the third OFDM tone block for the data portion of the PHY data unit.

Abstract: Embodiments described herein provide a method for resource unit signaling with reduced data bits in a wireless local area network. At a wireless transceiver, a data frame may be obtained for transmission. The data frame includes a first preamble portion and a second preamble portion compliant with a wireless local area network communication protocol. When an available resource unit for transmitting the data frame is less than an allowed bandwidth, the first preamble portion and the second preamble portion may be configured with resource unit signaling bits. When the available resource unit is greater than or equal to the allowed bandwidth, the resource unit may be virtually divided into a plurality of channels. At least one of the first preamble portion and the second preamble portion may be configured with a first number of bits representing a number of users spatially multiplexed on a channel from the plurality of channels.
