    Abstract: Systems and methods are disclosed for operating an interface of an electronic device in an active mode or a power save mode based, at least in part, on a condition of a data exchange module buffer. When buffer space is available, incoming data may be stored locally and the interface used to access remote memory storage may be in a power save mode. The interface may revert to active mode to transfer data to the remote memory, such as after a configurable reception interval. Outgoing data may also be stored in a buffer, allowing the interface to be in a power save mode with information transmitted from the buffer.

    Abstract: Methods, systems, and devices are described for establishing a virtual communication link including at least a first and second physical link between two devices. A single virtual packet queue of a device may receive one or more data packets to be transmitted via the virtual communication link. The single virtual packet queue may attach a virtual sequence number to each of the one or more data packets and send the one or more data packets to one or more of the first or the second physical link according to the assigned virtual sequence numbers. The one or more packets may then be communicated via the first and/or second physical links according to link specific sequence numbers, such as medium access control (MAC) sequence numbers, assigned to the one or more data packets by the first and/or second physical links.

    Abstract: A method of performing MIMO wireless communication includes identifying a first wireless device that qualifies for inclusion in a multi-user (MU) group and identifying a set of one or more candidate wireless devices, distinct from the first wireless device, that qualify for inclusion in the MU group. The set includes a second wireless device. A determination is made that an estimated MU-mode net goodput for the first and second wireless devices is greater than an estimated average single-user-mode net goodput for the first and second wireless devices. The first and second wireless devices are included in the MU group based at least in part on the determination. A transmission is sent to the MU group. Net goodput corresponds to a number of bits that may be successfully transmitted divided by a sum of a time to transmit the number of bits and a time associated with network overhead.

    Abstract: Embodiments of the present invention provide for content optimization of a physical layer preamble. In one embodiment of the invention, a method for encapsulating a payload for transmission through a network is disclosed. The method comprises the step of programming a legacy physical layer length value in a legacy physical layer preamble. The legacy physical layer preamble is configured such that it can be received by any legacy stations that may be on the network, and such that a separate physical layer length value can be derived from the legacy physical layer preamble. Using such a system, content optimization of a physical layer preamble is provided.

    Abstract: This disclosure includes systems and methods for determining the location of each of a plurality of STAs of a WLAN where an AP measures the round-trip time (RTT) and the angle of arrival (AOA) to each STA from implicit packet exchange, such as data frame and ACK frame. The AP may then report the RTT and AOA measurements to each STA using a dedicated beacon information element (IE) which multicasts RTT and AOA measurements to the STAs. By employing an additional parameter, namely, angle of arrival AOA, a single AP may compute the two-dimensional location of each associated STA. Further, another beacon IE may multicast mapping of the AIDs to MAC addresses so that the associated STAs can understand such mapping for STAs in a network so that one STA may know the location of other STAs. Encryption may be employed to achieve privacy.

    Abstract: A method and apparatus for broadcasting short interframe space information to aid in determining a round trip time are provided. The round trip time is used as an aid in locating nodes within a WiFi or WLAN network. The method begins with capturing a time of transmission of a frame by a transmitting station. The receiving station then captures the time of arrival of the frame just sent by the transmitting station. The receiving station replies with a received frame message and the time of departure is captured. The transmitting station then captures the time of arrival of the received frame message. The captured arrival and departure times of the frame and the received frame message allow the round trip time to be computed. The RTT may then be included as part of a network message.
