    摘要： This disclosure describes systems, methods, and devices related to long training field (LTF) sequence security protection. A device may determine a null data packet (NDP) frame comprising one or more fields. The device may determine a first long training field (LTF) and a second LTF, the first LTF and the second LTF being associated with a first frequency band of the NDP frame, wherein time domain LTF symbols of first LTF and the second LTF are generated using different LTF sequences. The device may determine a third LTF and a fourth LTF, the third LTF and the fourth LTF being associated with the a second frequency band of the NDP frame, wherein time domain LTF symbols of third LTF and the fourth LTF are generated using different LTF sequences. The device may cause to send the NDP frame to an initiating or a responding device. The device may cause to send a location measurement report (LMR) frame to the initiating or the responding device, wherein the LMR comprises timing information associated with the first frequency band and the second frequency band.

    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.

    摘要： Embodiments described herein relate generally to a user equipment (“UE”) that is to transmit and receive signals associated with synchronization. The UE may be receive signals associated with synchronization from a plurality of synchronization sources, such as an evolved Node B (“eNB”), a global navigation satellite system (“GNSS”), or another UE. The UE may synchronize to a signal received from a synchronization source based on a priority associated with that synchronization source and/or signal. However, if the UE does not receive any signals associated with synchronization, the UE may generate and transmit a signal that indicates a request for synchronization.

    摘要： In some embodiments a beamforming method is disclosed. The method can include transmitting a beam having a channel defined by a maximum ration transmission vector (MRT) and receiving a first response from a receiver, where the first response has first information such as parameters related to the transmitted beam. Using the parameters and the initial MRT another directional transmission can be made. A similar process can determine a maximum combining ratio for a receiver. Set up communications between the transmitter and the receiver can be reduced by omitting data from transmission that can be acquired by other means such as from memory or calculations. Additional embodiments are also disclosed.
