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.
