    摘要： Example systems, methods, and devices for mitigating interference in wireless networks are discussed. One example method includes the operations of passing channel frequency offsets of a plurality of LTF symbols on a plurality of subcarriers through a high pass frequency band, encoding the plurality of LTF symbols with a plurality of LTF sequences across frequency, and encoding the LTF symbols in time and/or frequency. Another example includes the operations of receiving a plurality of LTF symbols on a plurality of subcarriers for channel estimation of one or more streams, removing the encoding across time, removing the encoding across frequency, and removing the LTF sequence(s), and passing the modified LTF symbols through a smoothing filter, for example, a low pass filter for removing the interference due to CFOs. Methods, apparatus, and systems described herein can be applied to 802.11ax or any other wireless standard.

    摘要： The present disclosure relates to computer-implemented systems and methods for facilitating simultaneous poll responses. A method may include assigning respective subsets of subcarrier frequencies to a plurality of user devices for communication over a wireless channel. The method may also include transmitting, simultaneously, a channel status request poll to the user devices. Additionally, the method may include determining, based at least in part on a first channel status response received via a first subset of subcarrier frequencies over the wireless channel, that the first channel status response is received from the first user device. Similarly, the method may also include determining a second channel status response is received from a second user device. Furthermore, the method may include determining, based at least in part on the first channel status response and the second channel status response, to schedule simultaneous data communication for the first device and the second device.

    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.
