摘要： A method of transmitting universal serial bus (USB) frames over a communications channel is disclosed. A USB device receives one or more USB frames from a host device via a network, wherein the one or more USB frames are encapsulated in one or more data packets based on a communications protocol associated with the network. The USB device further synchronizes a local clock signal with a clock signal of the host device using a clock synchronization mechanism of the communications protocol. The USB device then determines a number of USB frames transmitted by the host device and processes the one or more USB frames based, at least in part, on the synchronized local clock signal. For some embodiments, the USB device may receive a frame count value and a corresponding media time value from the host device.

摘要： Methods, devices, and computer program products for collision management of wireless devices in a peer-to-peer network are described herein. In one aspect, a method of communicating via a wireless medium by a wireless communications apparatus within a neighborhood aware network is provided. The network is configured with periodic discovery windows, and sized for a maximum number of devices M. The method includes determining a discovery window interval K, the smallest integer greater than or equal to one, such that the probability that more than a threshold M devices will transmit during the same discovery window is less than a threshold probability P. The method further includes selecting a random or pseudo-random integer m in the range from 0 to K-1, deferring for at least m discovery windows after a previous interval K-1 has elapsed, and transmitting a discovery frame during the next discovery window after said deferring.

摘要： This disclosure provides methods, devices and systems for improving the security of secure long training field (LTF) transmissions. In some implementations, a transmitting device may perform windowing on a secure LTF, in the frequency domain, so that the resulting time-domain LTF signal is difficult, if not impossible, to predict by any device that observes a portion of the LTF signal. In some aspects, the transmitting device may negotiate the windowing of secure LTFs with a receiving device based on fine timing measurement (FTM) negotiation frames exchanged at the start of an FTM procedure. In some other aspects, the transmitting device may dynamically or adaptively perform windowing on secure LTFs. In such aspects, the transmitting device may indicate whether windowing is performed on a secure LTF based on information carried in a signal field of a physical layer convergence protocol (PLCP) protocol data unit (PPDU) that includes the secure LTF.

摘要： Methods, systems, and devices for wireless communication are described. A ranging message procedure may employ protection by modifying a cyclic prefix of the ranging message to prevent an attacking device from transmitting a time-advanced copy of the cyclic prefix during symbol of the copied signal. For example, the modified cyclic prefix may include pseudo random training sequences or a set of zero-value symbols. The receiving device may determine a channel estimation technique that accounts for the modified cyclic prefix. The wireless devices performing the ranging measurement process may determine a modulation and coding scheme (MCS) for the ranging message. The wireless devices may negotiate an MCS value and cyclic prefix configuration for the ranging measurement process. In some examples, the ranging message be encoded by applying a sequence of phase rotations or amplitude variations to the base sequence used to generate the sounding training signal.

摘要： This disclosure provides systems, methods and apparatuses for dynamically changing one or more operating parameters of a wireless network. In some aspects, an AP may detect the presence of an overlapping BSS having the same color as its own BSS. Upon detecting a color collision, the AP may temporarily disable color-related features (such as intra-PPDU power save, multi-NAV operation, spatial reuse, and the like) of its associated STAs. If the color collision persists beyond a threshold duration, the AP may dynamically change the color of its own BSS to a different BSS color. In some other aspects, the AP may detect the presence of an overlapping BSS having the same TBTT as its own. Upon detecting a beacon collision, the AP may expedite or delay the timing of its own TBTT so that it does not interfere or overlap with the TBTT of another BSS.

摘要： A wireless device (e.g., a station (STA)) may receive a transmission soliciting a control transmission (e.g., a soliciting transmission). The STA may identify a transmission parameter indicator, which may indicate a change in one or more parameters in a control response transmission parameter set (e.g., a set of parameters used for control transmissions in response to the soliciting transmission). The STA may transmit the control transmission in response to the soliciting transmission based on the identified transmission parameter indicator. The control response transmission parameter set may include a frame format, a physical layer convergence protocol (PLCP) protocol data unit (PPDU) format, a bandwidth, a modulation scheme, an encoding scheme, a modulation and coding scheme (MCS), a number of spatial streams (NSS), and/or a PPDU duration. In some cases, the transmission parameter indicator may indicate disabling or resumption of extended range (ER) single user (SU) PPDU format usage.
