摘要： A passive intermodulation detection system is provided to remotely identify passive intermodulation at a base station site and diagnose the type of intermodulation and location of the non-linearity that is the source of the passive intermodulation. The passive intermodulation detection system can generate a test signal in a first band that is transmitted by an antenna. Another antenna can receive a signal in another band, and the passive intermodulation detection system can analysis the received signal to determine whether an intermodulation product due to a non-linearity is present. Based on the type of intermodulation product, period, order, frequency, and etc., the type and location of the non-linearity can be identified.

摘要： Aspects relate to temporarily disabling a message or a set of messages based on the detection that an uplink transmission power is reaching maximum power or is at maximum power. The detection can be based on observing that one or more uplink transmissions are near, or at, the maximum power. The message or set of messages that are disabled can be a non-call critical message(s), such as a non-signaling radio bearer related message(s). Disabling the message or set of messages can conserve resources, which can be utilized for call critical messages, which can include signaling radio bearer related messages, call maintenance messages, voice communications, and so forth. Disabling the message or set of messages can also mitigate the chances of a call being disconnected due to power demands that exceed the maximum power available.

摘要： Embodiments for port reconfiguration for passive intermodulation interference mitigation are presented herein. A base station device comprises a signal processing component comprising a passive intermodulation interference component and an antenna configuration component. The passive intermodulation interference component determines passive intermodulation interference corresponding to uplink signals that have been received, via a configurable cellular antenna array of the base station device, from respective wireless devices of a group of wireless devices that have been communicatively coupled to the base station device. The antenna configuration component selects a defined configuration of a group of cellular antenna ports of the configurable cellular antenna array to facilitate a reduction of the passive intermodulation interference corresponding to the uplink signals.

摘要： A passive intermodulation detection system is provided to remotely identify passive intermodulation at a base station site and diagnose the type of intermodulation and location of the non-linearity that is the source of the passive intermodulation. A passive intermodulation cancelation system can generate an equivalent signal to a received interference signal and use the equivalent signal to generate an error signal. The error signal can then be used to reinforce a learning system and converge on a steady state of the interference signal to cancel other interference signals.
