A system that incorporates the subject disclosure may include, for example, a method for mitigating interference by filtering or redirection of communications traffic. Other embodiments are disclosed.

A system that incorporates aspects of the subject disclosure may perform operations including, for example, obtaining performance parameters in a communications network, identifying a degradation in performance of one or more nodes of the communications network according the monitored performance parameters, and initiating corrective action to mitigate the degradation in performance of the one or more nodes of the communications network. Other embodiments are disclosed.

A system that incorporates aspects of the subject disclosure may perform operations including, for example, obtaining performance measurements for a number of sectors or a number of paths and determining whether one or more of the performance measurements are below a threshold. A power level of at least a portion of a received uplink signal is adjusted to increase a performance measurement of an affected sector of the number of sectors or an affected path of the number of paths falling below the threshold. A determination is made as to whether the adjusting of the power level of at least the portion of the received uplink signal has improved the performance measurement of the affected sector or the affected path. Other embodiments are disclosed.

The disclosure describes embodiments for reducing adjacent channel interference for wireless vehicular messages. In some embodiments, a method includes monitoring, by an onboard vehicle computer, a channel of a Vehicle-to-Everything (V2X) radio for a V2X message. The method includes determining waveform data describing a waveform that is measured on the channel by the onboard vehicle computer when monitoring the channel. The method includes determining interference data which describes an adjacent channel interference waveform which is measured on the channel by the onboard vehicle computer when monitoring the channel. The waveform includes the adjacent channel interference waveform. The method includes canceling out the adjacent channel interference waveform described by the interference data from the waveform described by the waveform data to generate digital data describing a version of the V2X message that substantially does not include the adjacent channel interference waveform, thereby reducing the adjacent channel interference for the V2X message.

Compensation is provided for foreign interference within a cell. Uplink (UL) noise on an UL channel to a first base station (BS) device is detected. Whether the UL noise includes interference is determined. Interference can include any device other than a mobile device configured to communicate with a BS device associated with a cell. The first service area of the BS device can be modified, e.g., scaled based on determining that the UL noise includes interference. Scaling can include reducing the first service area to a second service area that does not include an imbalance region in the first service area caused by the foreign interference. Scaling can be effected by reducing the amount of downlink power from the first BS device, or by adjusting a re-selection parameter associated with reducing the range of the BS device.

Indication of an amount of processing performed in detection and removal of ingress noise may be provided. A frequency domain representation of a narrowband region of a digital input signal may be received. The received frequency domain representation of the narrowband region may be compared with a predetermined threshold. Results from the comparison of the received frequency domain representation of the narrowband region with the predetermined threshold may be aggregated. Based on the aggregated results, an indication of an amount of processing performed by an ingress exciser in removing the ingress noise may be provided.

A system that incorporates the subject disclosure may perform, for example, a method that determines at least one threshold for detecting signal interference in a first plurality of segments occurring in a first radio frequency spectrum of a first wireless communication system, detecting a pattern of recurrence over time of signal interference in a segment of the first plurality of resource blocks according to the at least one threshold, and performing one or more mitigation steps to mitigate the signal interference without filtering the signal interference where the one or more mitigation steps include at least one of transmitting signals out of phase from the signal interference, adjusting transmit power, increasing power in a resource block of a long term evolution communication session, performing beam steering, or changing time parameters for the resource block without changing to a new resource block. Other embodiments are disclosed.

A system that incorporates the subject disclosure may perform, for example, a method for receiving interference information from each of the plurality of communication devices detecting interference information in a plurality of segments of a radio frequency spectrum, correlating the interference information of the plurality of communication devices to generate correlated information, and identifying a plurality of interferers according to the correlated information. Other embodiments are disclosed.

A securely pre-coded orthogonal frequency division multiplexing (SP-OFDM) system includes a transmitter configured to transmit a secure transmit signal through a dynamic constellation and a receiver configured to recover the original signal from the received secure transmit signal. It is aimed to reinforce the physical layer security of wireless communications under hostile interference. Potential applications include 4G and 5G communication systems, ASTC3.0 HDTV systems, WiFi systems, and any future wireless systems that utilize OFDM.
