Abstract: Example methods and systems for policy-aware traffic forwarding for multiple types of network traffic are described. In one example, a computer system may extract identification information associated with a first client, wherein the first client is associated with a first type of network traffic and obtain a first policy associated with the first client. In response to detecting first network traffic of the first type from the first client, the computer system may (a) interwork the first network traffic into a data plane entity associated with the second type of network traffic, and (b) forward the first network traffic via the data plane entity according to the first policy. In response to detecting second network traffic of the second type from a second client, the computer system may forward the second network traffic via the data plane entity according to a second policy associated with the second client.

Using the first timer, a second timestamp associated with an end time of the first client transaction is identified. Using the second timestamp, the first data frame is updated using the second timestamp. The first data frame is sent to the cloud computing device.

Abstract: A mobile device transmits data over a shared spectrum in an uplink channel to a base station in a contention-based access scheme. The mobile device obtains data to be wirelessly transmitted over the shared spectrum in the uplink channel to the base station. The uplink channel is formatted with a frame/subframe structure with a predetermined timing. The mobile device determines whether the shared spectrum is free for transmission according to a listen before transmit procedure. When the shared spectrum is free for transmission, the mobile device contends with other mobile device to gain access to the uplink channel. After gaining access to the uplink channel, the mobile device transmits the data over the shared spectrum in the uplink channel to the base station.

Abstract: An access point (AP) transmits Wi-Fi transmit frames according to a Wi-Fi protocol and Long-Term Evolution-Unlicensed (LTE-U) transmit frames according to an LTE-U protocol in a shared channel bandwidth that encompasses unlicensed channel bandwidth associated with the LTE-U protocol. The AP assigns a Wi-Fi access category to each Wi-Fi transmit frame and assigns to each LTE-U transmit frame an LTE-U access category. The AP schedules Wi-Fi and LTE-U transmit opportunities for the Wi-Fi transmit frames and the LTE-U transmit frames, respectively, in the shared channel bandwidth based on the Wi-Fi and LTE-U access categories. The scheduling includes, for each scheduled LTE-U transmit opportunity: constructing a Wi-Fi quiet message commanding Wi-Fi clients of the AP not to transmit in the shared channel bandwidth during the LTE-U transmit opportunity; and scheduling the Wi-Fi quiet message for transmission to the Wi-Fi clients.

Abstract: Data to be transmitted to a user device may be received at a network device. It may be determined that the user device has network connectivity to the network device via a wide area wireless network connection and that the user device also separately has connectivity to the network device via a local area wireless network connection to an access point. The data may be split so that some portion of the data is to be transmitted by the wide area wireless network connection and another portion of the data is to be transmitted by the local area wireless network connection.

Abstract: An LAA-LTE wireless device obtains data to be transmitted in subframes over a shared spectrum. The wireless device transmits a reservation message over the shared spectrum. The reservation message indicates that an initial synchronization message will be retransmitted a specified number of times at specified intervals, such as with a predetermined number of subframes between each retransmitted synchronization message. The wireless device transmits the initial synchronization message over the shared spectrum.

Abstract: A first wireless device determines the duration of a clear channel assessment interval based on feedback signals before transmitting data to a second wireless device. The first wireless device receives feedback signals, such as acknowledgement (ACK) and negative acknowledgement (NAK) signals, from one or more second wireless devices. The first wireless device determines a ratio of NAK/ACK signals in the feedback signals for a predetermined amount of time. The first wireless device determines whether the wireless medium is free by monitoring for wireless signals during a clear channel assessment interval. The duration of the clear channel assessment interval is based on the ratio of NAK/ACK signals. If the wireless medium is free for the duration of the clear channel assessment, the first wireless device wirelessly transmits data to at least one of the second wireless devices.

Abstract: A mobile device obtains data to be wirelessly transmitted over a shared spectrum in an uplink channel to a base station. The uplink channel is formatted with a frame/subframe structure with a predetermined timing. The mobile device determines whether the shared spectrum is free for transmission according to a Listen Before Transmit procedure. When the shared spectrum is free for transmission, the mobile device selects a start time in the uplink channel that mitigates interference from other mobile devices in proximity to the mobile device. Beginning at the start time, the mobile device transmits the data over the shared spectrum in the uplink channel to the base station.

Abstract: Modifications to frame/subframe structure are presented herein so that a wireless device can transmit its data within a fraction of a subframe. The device obtains data to be transmitted in an unlicensed spectrum and determines whether an entire subframe is required to completely communicate the data. If the data is small enough to not require the entire subframe, then the device generates a burst transmission to minimize the time period of the subframe used to communicate the data. The device transmits the burst transmission and a parameter indicating the duration of the burst transmission.

Abstract: A wireless access point (AP) configured to operate in accordance with both Wi-Fi and Long-Term Evolution (LTE-U) standards/protocols jointly schedules transmit opportunities for Wi-Fi and LTE-U frames. The AP assigns one of multiple, prioritized, Wi-Fi access categories to each Wi-Fi transmit frame based on a type of data in the transmit frame. The AP also assigns to each LTE-U transmit frame an LTE-U access category prioritized relative to the Wi-Fi access categories. The AP schedules Wi-Fi and LTE-U transmit opportunities for the Wi-Fi transmit frames and the LTE-U transmit frames, respectively, in the shared channel bandwidth based on the prioritized Wi-Fi and LTE-U access categories.

Abstract: A wireless device accesses a shared spectrum equitably in a self-organizing manner by determining success indices and adjusting courtesy parameters. The wireless device transmits wireless transmissions in a frame subframe structure over a shared spectrum, each of the subframes bounded by subframe boundaries at predetermined time intervals. The success index represents a measure of success in transmitting wireless transmissions in the shared spectrum. The wireless device performs a clear channel assessment to determine whether the shared spectrum is available at the end of the clear channel assessment time interval. The wireless device determines a gap interval between the end of the clear channel assessment time interval and the next subframe boundary and transmits the success index during the gap interval.

Abstract: A first network device may operate as a base station in a wireless wide area network (WWAN) and may establish a WWAN connection with a user device. A media access control (MAC) address of the user device may be obtained and sent to a second network device which operates an access point for a wireless local area network (WLAN). An acknowledgement containing a first service set identifier of the WLAN may be received from the second network device and sent to the user device to set up a secondary connection. An identifier for ordered data communication may used to enable in order communication through both the first and the second network devices. Data to be transmitted to the user device may be split into a first portion and a second portion, and transmitted through the WWAN connection and to the second network device for transmission to the user device via the WLAN respectively.
