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: Systems and methods for providing host-neutral small cells include communicating with a first User Equipment (UE) at a small cell. The first UE communicates with the small cell via a first Evolved Node B (eNodeB) base station associated with a first Evolved Packet Core (EPC). The small cell further communicates with a second UE. The second UE communicates with the small cell via a second eNodeB base station associated with a second EPC. Although a different wireless carrier may be associated with each of the first and second UEs, they may both communicate with the host-neutral small cell.

Abstract: A Long-Term Evolution-Unlicensed (LTE-U) access point (AP) is configured to operate wirelessly on any of multiple RF channels in an unlicensed frequency band. The AP detects other LTE-U APs and Wi-Fi APs operating on active ones of the multiple channels. The AP determines AP channel statistics for each detected AP. The AP determines, for each active channel, a per-channel metric based on the AP channel statistics. The AP ranks the active channels according to the corresponding per-channel metrics, and selects a best channel on which to transmit in the unlicensed frequency band from among the ranked active channels based on the rankings.

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: A controller controls access points (APs) in a network of APs. The controller causes the first AP to establish an Internet Protocol (IP) tunnel with a router connected with a wired network and over which data packets are routed between the wired network and a client device wirelessly connected to the first AP. The controller receives a roam indication that the client device is wirelessly connected with a second AP. In response to the indication, the controller instructs the first AP to maintain the IP tunnel with the router and instructs the second AP to establish an inter-AP tunnel with the first AP in order to route traffic between the wired network and the client device over both the IP tunnel and the inter-AP tunnel.

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: 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.

The mechanisms enhance the baseline energy detection mechanism by incorporating methods to decode cross-technology physical layer elements and media access control (MAC) layer elements in the Wi-Fi system to elements in the SAC-LTE system. The methods described improve the detection potential for transmitters, thereby reducing chances of cross-technology collisions.

Abstract: Modifications to frame/subframe structure are presented herein so that a wirelessdevice 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 method and apparatus are provided for managing radio access point (RAP) devices and enterprise controller devices in a wireless communication network. An enterprise controller device registers with a gateway device, and the enterprise controller device receives a registration request from multiple RAP devices that are serviced by the enterprise controller device. As the RAP devices register with the enterprise controller device, the enterprise controller device generates a list of the RAP devices registered with the enterprise controller. As the enterprise controller receives additional registration requests from additional RAP devices, the enterprise controller updates the list. The enterprise controller sends the list to the gateway device with which it registers so that the gateway device is aware of RAP devices serviced by the enterprise controller device. In this way, aggregated messages may be sent from the gateway device to the enterprise controller.
