Abstract: Embodiments described herein provide systems for processing high efficiency SIGB (HE-SIGB) symbols and extracting resource unit (RU) information in down link orthogonal frequency division multiple access (DL-OFDMA) and multi-user multiple input multiple output (DL-MUMIMO) communication. An HE-SIGB symbol is processed based on an RU size mapping table. An RU counter is used to process entries in the RU size mapping table and determine the RU size and starting tone index of the intended RU. The RU parameters extracted from the HE-SIGB symbol are used to decode data symbols in the DL-OFDMA or DL-MUMIMO packet. Pilot tone indices of the intended User block and adjacent pilot tone indices are determined for improved carrier phase error estimation.

Abstract: A method for deinterleaving a plurality of resource units (RUs) where each RU includes data and parameters. The method includes assigning each RU into one of a first deinterleaver and a second deinterleaver and storing the parameters of each respective RU to a respective buffer in an order. The method also includes processing the data of the respective RU in the one of the first deinterleaver and the second deinterleaver and upon completion of the processing of the data of a respective RU, outputting the data of the respective RU from the one of the first deinterleaver and the second deinterleaver into which the respective RU was assigned, outputting the parameters of the respective RU corresponding to one of the first deinterleaver and the second deinterleaver into which the respective RU was assigned, and aligning the parameters of the respective RU with the data of the respective RU based on the order of storage of the parameters in the respective buffer.
