    摘要： A STA, AP and method of reducing channel allocation control overhead are disclosed. The STA receives a high-efficiency Physical Layer Convergence Protocol Data Unit (HE PPDU) having a HE SIG-A field followed by a HE SIG-B field. The SIG-B field has user-specific subfields (USS), each having a stream allocation value (SAV) for an associated STA and associated with a unique stream index number (SIN) indicating a position among the USSs. The SINs increase with increasing position from the SIG-B field. The number of channels allocated in each USS is constrained to stay the same or monotonically change with increasing SIN. The STA determines channel allocation from the SAV, SIN and number of USSs. The channels may be allocated non-contiguously. The SAVs in most USSs may indicate an allocation to increasing or decreasing channels and in the final USS to at least one channel starting from a final or initial channel.

    摘要： Apparatuses, methods, and computer readable media for indicating a communication and information in a signal field are disclosed. A high-efficiency wireless local area network (HEW) device comprises circuitry is disclosed. The circuitry may be configured to: generate a HEW packet comprising a legacy signal (L-SIG) field, where the L-SIG field comprises a plurality of subcarriers, and an R-L-SIG field, where the R-L-SIG field comprises a repeat of the plurality of subcarriers partitioned into a plurality of groups, and where information is encoded into one or more groups of the plurality of groups by a same modulation to each subcarrier partitioned into the corresponding group. A HEW device comprising circuitry is disclosed. The circuitry may be configured to: receive a L-SIG field; receive a R-L-SIG field; and determine whether the R-L-SIG field is a repeat of the L-SIG field with piggybacked information.

    摘要： Embodiments herein relate to wireless communication using combined channel training and physical layer header (SIG) signaling. Devices that comply with the 802.11ax or High Efficiency WLAN (HEW) standard may generate and transmit packets that include such combined information. The combined information may be beamformed to a receiver device via an OFDM signal, which may be decoded by the receiver device to obtain subsequent data included in the signal. For example, initial training symbols associated with channel training subcarriers in the signal may be detected and used to perform a rough estimate of the channel. The rough estimate may thereafter be refined using data symbols detected from adjacent data subcarriers using the channel training symbols. In this way, data subcarriers may also be used to determine a channel response along with channel training subcarriers. Channel training information may be transmitted with data, such as user-specific information, in a single symbol.
