  • Publication number: 20160183281
    Abstract: In a multiple Radio Access Technology (multi-RAT) heterogeneous wireless network, a user equipment (UE) is capable of communicating via multiple types technologies, such as both WiFi and Long Term Evolution (LTE) cellular. The evolved node B that the UE communicates with may be a small network, encompassing distances of 200 meters or less. A method communicating in such a network may involve using an on-time throughput scheduling algorithm that maximizes the throughput by handing off certain users and prioritizing communications based on specific criteria. These criteria may include prioritizing communications of users closest to a target threshold. The UE may communicate with the network to negotiate which radio access technology is to be used, a range of acceptable data rates.

  • Publication number: 20160173165
    Abstract: Disclosed are a method, computing device, and a non-transitory computer-readable medium storing computer-executable instructions which, when executed, cause a processor to perform operations, which may include: sending a transmit signal including non-linear elements; receiving another signal comprising at least a portion of the transmit signal through a receive chain of a computing device; simulating the transmit chain; generating, by the simulated transmit chain, a first signal associated with the transmit signal; generating a second signal by frequency shifting the first signal; generating one or more first kernels associated with the second signal; performing decimation of the one or more first kernels; transforming the one or more first kernels using a lower triangular matrix, into one or more second kernels; combining the one or more second kernels to generate an echo cancellation signal; and subtracting the echo cancellation signal from the received at least a portion of the transmit signal.

  • Publication number: 20160119939
    Abstract: Systems and methods for bearer splitting among multiple radio links are disclosed herein. User equipment (UE) may be communicatively coupled to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB) by multiple radio links (e.g., an LTE link and a WLAN link). A transmitter may dynamically determine a splitting policy for how to split traffic among each link (e.g., what proportion to send over each link). In some embodiments, the transmitter may determine the splitting policy explicitly based on lower layer metrics. Alternatively, or in addition, each radio access interface may request data when a transmission opportunity becomes available, and the splitting policy may be determined implicitly from the data requests. For a UE, the splitting policy may be determined with network assistance, which may include a resource allocation for an LTE link, a probability of successful transmission over a WLAN link, and/or the like.

  • Publication number: 20160073287
    Abstract: Technology for a user equipment (UE) to communicate in a multiple radio access technology (multi-RAT) heterogeneous network (HetNet) is described. A radio-link-selection hysteresis threshold can be determined at the UE for a radio link between the UE and a node in the multi-RAT HetNet. A reliability value of a throughput estimate can be measured for the radio link in the multi-RAT HetNet. The radio-link-selection hysteresis threshold can be adjusted at the UE based on the reliability value to increase network stability in the multi-RAT HetNet.

  • Publication number: 20160043937
    Abstract: A User Equipment is disclosed that is configured to perform traffic steering from a RAN (e.g., 3GPP system) to a WLAN, or vice versa, based on one or more rules. In an embodiment, the UE performs the traffic steering to the WLAN based on whether data is to be transmitted from or received by the UE. In another embodiment, the UE performs the traffic steering based on receipt of RAN assistance parameters without checking the status of the UE upload buffers or the eNB/AP download buffers. In yet another embodiment, the UE performs the traffic steering based on the latest RAN assistance information and a time elapsed since the last transmission or receipt of data.

  • Patent number: 9198184
    Abstract: A system provides dynamic interference avoidance in integrated multi-radio access technology (RAT) heterogeneous networks (Het-Nets). A multi-mode user equipment accesses mobile communications services using RATs. An integrated node provides a primary cell and at least one secondary cell to the multi-mode user equipment. Initial radio access technologies (RATs) are assigned to the multi-mode user equipment from among a plurality of RATs for use by the multi-mode user equipment. Quality metrics are collected across the plurality of RATs. RAT assignments are re-evaluated based on the collected quality metrics. To provide dynamic interference mitigation in multi-RAT Het-Nets, RAT assignments are periodically repartitioned from among the plurality of RATs for use by the multi-mode user equipment based on the re-evaluation of RAT assignments using the collected quality metrics.

  • Publication number: 20150271848
    Abstract: A user equipment (UE) is configured to receive a maximum probability of accessing a wireless local area network (WLAN) for communication. The maximum probability is received via a 3rd Generation Partnership Project (3GPP) communication link with an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). The UE is further configured to determine that there is a queued transmission for the UE and, in response to determining that there is a queued transmission, to determine whether the UE is authorized to access to the WLAN using a probability less than or equal to the maximum probability. The UE is further configured to delay contention for access to the WLAN for at least a pre-backoff duration in response to determining that the UE is not authorized.

  • Patent number: 8953482
    Abstract: Methods and devices for optimizing on-time throughput in a wireless network. An enhanced node B (eNodeB) integrating two or more air interfaces schedules transmissions, for a measurement period, over at least one of the two or more air interfaces. The eNodeB estimates, based on the transmissions, a metric of on-time throughput for the user equipment (UE) within the cell, where on-time throughput is a measure of an amount of data that arrives at a destination before a delay threshold has been reached and at a bit-rate greater than or equal to a target bit-rate. The eNodeB then assigns UEs within the cell to an air interface of the two or more air interface to maximize the metric of on-time throughput for the UEs within the cell.
