    摘要: This disclosure describes systems, and methods related to parallel channel training in communication networks. A first computing device comprising one or more processors and one or more transceiver component may receive a first connection request from a second computing device, and a second connection request from a third computing device. The first computing device may determine a first training field associated with the first connection request and a second training field associated with the second request. The first computing device may send the first training field to the second computing device based at least in part on the first connection request and sending in parallel, the second training field to the third computing device based at least in part on the second connection request. The first computing device may establish a first spatial channel stream with the second computing device based at least in part on the first training field and a second spatial channel stream with the third computing device based at least in part on the second training field.

    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 of the disclosure provide auto-detection in wireless telecommunications. Certain embodiments provide or otherwise implement a specific sequence of bits and/or symbols for auto-detection. The specific sequence of bits can be embodied in or can include output codebits from an encoder in a communication device that can send a wireless transmission including the specific sequence. In one embodiment, the encoder can compute or otherwise generate cyclic redundancy checks (CRCs) or other types of validation checks at the communication device. The specific sequence can be determined using the payload of a packet frame. Both the manner in which the specific sequence is generated and the temporal order in which the specific sequence is received relative to other payload in the packet frame can provide specificity to the sequence.
