    Abstract: Embodiments of a packet structure for frequency offset estimation and method for UL MU-MIMO communication in high-efficiency Wi-Fi (HEW) are generally described herein. In some embodiments, the packet structure may comprise a short training field (STF), a number of long-training fields (LTFs) following the STF, a signal field (SIGB)to follow the LTFs, and a data field to follow the signal field. The data field may comprise an UL MU-MIMO transmission from a plurality of scheduled stations. The number of LTFs may be equal to or greater than a number of data streams as part of the UL MU-MIMO transmission, and the plurality of scheduled stations may share the number of LTFs by transmitting on different orthogonal tone sets.

    Abstract: This disclosure describes systems, methods, computer readable media, and/or apparatus related to encoding wireless communication preamble structures with cyclic redundancy check (CRC) that is performed on both a common part, as well as, station specific parts of a signaling field. The signaling field generated by this mechanism may be relatively shorter, resulting in less preamble overhead, than if a separate CRC was to be provided for each of the station specific parts, as well as the common part of the signaling field. In additional embodiments, tail bits may be provided for a combination of the common part of the signaling field and each station specific part of the signaling field. Compared to providing tail bits separately for the common part and each of the station specific parts, removing the tail bits from the tail bits form the common part may result in relatively less overhead of the preamble structure.
