Failover to a backup policy and charging rules function (PCRF) node
A telecommunication network associated with a wireless telecommunication provider can be configured to use a backup PCRF when a primary PCRF is detected as exhibiting a failure condition. Instead of the backup PCRF synchronizing with the primary PCRF as in a redundancy mode, the backup PCRF receives a copy of messages sent to the primary PCRF and maintains session information independently from the primary PCRF. In some configurations, a node within the call flow, such as a Diameter Routing Agent (DRA) transmits a copy of the message sent to the primary PCRF to the backup PCRF. In this way, the backup PCRF will not receive data from the primary PCRF that may be corrupted. When a routing agent detects a failure condition of the primary PCRF, the routing agent seamlessly transitions to use of the backup PCRF. |

Independent transmit and receive channel calibration for multiple-input multiple-output (MIMO) systems
This document describes techniques and systems for independent transmit and receive channel calibration for multiple-input multiple-output (MIMO) systems. Antenna responses are collected from each virtual channel of a MIMO system at an angle respective to an object. The transmit components and the receive components of the virtual channels are separated and organized into vectors (one for the transmit components and one for the receive components). Calibration values for elements of the vectors are computed and maintained in a transmit calibration matrix and a receive calibration matrix, respectively. Together, the transmit calibration matrix and the receive calibration matrix may include fewer elements than a calibration matrix for the virtual channels and, therefore, may require less memory and fewer computations to calibrate a MIMO system than using other calibration techniques. As such, described is a less expensive and less complex way to calibrate MIMO system by accurately approximating an ideal antenna array. |

Active duplexer
A front-end module of a wireless device can replace a passive duplexer with an active duplexer that uses metamaterial matching circuits. The active duplexer can be formed from a power amplifier circuit and a low noise amplifier circuit that each include a metamaterial matching circuit. The combination of a power amplifier circuit and a low noise amplifier circuit that each utilize metamaterials to form the associated matching circuit can provide the functionality of a duplexer without including the additional circuitry of a stand-alone or passive duplexer. Thus, in certain cases, the front-end module can provide duplexer functionality without including a separate duplexer. Advantageously, in certain cases, the size of the front-end module can be reduced by eliminating the passive duplexer. Further, the loss introduced into the signal path by the passive duplexer is eliminated improving the performance of the communication system that includes the active duplexer. |
