Abstract: The present invention provides a method and system for receiving a plurality of transmission signals at a receiver, the transmission signals each traveling through a corresponding transmission channel. The receiver includes a plurality of receiver channels, a receiver channel corresponding to each transmission channel. Each receiver channel receives a corresponding transmission signal. The received transmission signals are detected to determine whether the received transmission signals are dominated by noise or interference. If the received transmission signals are dominated by noise, then a first set of weights are selected as a receiver weighting. If the received transmission signals are dominated by interference, then a second set of weights are selected as the receiver weighting. The received transmission signals are estimated based upon the receiver weighting. Detecting whether the received transmission signals are dominated by noise or interference includes determining a level of correlation between the received transmission signals. Detecting whether the received transmission signals are dominated by noise or interference can be determined during a time slot of nulled transmission signals. If the transmission signals are multiple carrier signals, then detecting whether the received transmission signals are dominated by noise or interference can be determined during a frequency and time slot of a nulled carrier of the transmission signals. The first set of weights can be based upon a first covariance matrix, wherein the first covariance matrix represents received noise and interference covariance. The second set of weights can be based upon the second covariance matrix, wherein the second covariance matrix represents interference covariance. The first set of weights and the second set of weights can also be used for transmission mode selection and receiver soft decoding.

Abstract: An integrated WLAN/WWAN architecture is described, in which signaling used to control the integration of the WLAN/WWAN architecture is performed over the Radio Resource Control (“RRC”) plane. The integrated architecture may provide a network-controlled framework for performing traffic steering and radio resource management. Additionally, according to the disclosure provided herein, the integrated architecture may interwork with legacy systems (e.g., architectures that do not support the integrated WLAN/WWAN architecture).

Abstract: Embodiments of wireless communication devices (WCDs) and methods for cancelling signal interference in the WCDs are generally described herein. Some of these embodiments describe a WCD that includes a receiver to generate a received signal, which includes at least a first signal transmitted to the WCD by a network station that operates in a full-duplex mode while the WCD operates in a half-duplex mode. The WCD also includes a module to generate an interference cancellation signal for the received signal based on interference information obtained from at least the received signal. The interference information is associated with a second signal transmitted to the network station by an additional device. The first signal is transmitted while the second signal is transmitted. The first and second signals include the same radio-frequency (RF) carrier.

Abstract: Embodiments of a base station and method for reducing asynchronous interference in a multi-tier OFDMA overlay network are generally described herein. In some embodiments, a lower-tier base station is configured to adjust OFDMA frame boundaries to cause frames communicated by a higher-tier to arrive within a cyclic prefix at the lower-tier base station. The lower-tier base station may also be configured to adjust OFDMA frame boundaries to cause frames communicated by a lower-tier of the network to arrive within a cyclic prefix at a higher-tier mobile station. Accordingly, frames from one tier may arrive within the cyclic prefix of another thereby reducing asynchronous interference.

Abstract: Embodiments of computer-implemented methods, systems, computing devices, and computer-readable media are described herein for opportunistically transitioning service flows of mobile devices between being direct and indirect. In various embodiments, a proximity between first and second mobile devices that are in wireless communication with each other may be monitored. In various embodiments, a selective transition of a service flow between the first and second mobile devices from being indirect through the radio network access node using a first radio access technology (“RAT”) to being direct using a second RAT may be facilitated, e.g., responsive to a determination that a first criterion has been met. In various embodiments, a selective transition of the service flow from being direct using the second RAT to being indirect using the first RAT may be facilitated, e.g., responsive to a determination that a second criterion has been met.

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.

Abstract: The method (600) involves receiving a configuration of discontinuous reception (610) that is levelled with a multi-radio wireless device e.g. cell phone, from an evolved node B. The wireless device is arranged with a set of radio operated transmitter-receivers. The configuration of discontinuous reception is applied (620) to one of the set of radio operated transmitter-receivers. A shift period is selected (630) among a cycle of 2 milliseconds (ms), 5ms, and 8ms for long discontinuous reception cycle. Independent claims are also included for the following: (1) a multi-radio wireless device (2) a computer readable medium comprising instructions for performing an interference reduction method.
