The UE transmits, to a location server, a capability message that indicates position capabilities of the UE to support different positioning methods and common information related to the position methods, including that the UE is a NB UE. The UE receives a request for location information that includes a request for positioning measurement for a particular positioning method, a NB message size limit that indicates a limit on an amount of location information to return, and a NB response time to provide the positioning measurements. At least one of the response time or message size limit is different than for the NB UE than for non-NB UEs. The UE enters an idle state, performs the measurements, and transmits at expiry of or before the NB response time, a message containing the measurements.

  • Patent number: 11405872
    Abstract: Systems and methods are provided for managing uplink interference in a high noise environment. In response to determining that an observed received signal strength indicator (RSSI) exceeds a reference RSSI, a user device may be determined to be disposed in a high noise environment. In order to mitigate the impact of the high noise environment on the uplink, one or more interference mitigation procedures may be executed that may directly, or result in, the handoff of the user device from a first cell with a greater noise to a second cell with less noise.

  • Patent number: 11329679
    Abstract: Methods and systems for interference management are described. Methods and systems can be used for minimizing interference among communication and/or electronic devices. Interference data can be gathered/received from interference sources such as weather and natural patterns, various electronic devices, and one or more network protocols. The interference data can be used to generate interference patterns of each interference source in an interference map. The interference map can be used to determine how a particular interference pattern can affect a system. The interference map can also be used to evaluate a new source of interference (e.g., cordless phones, weather conditions) to determine how a system can be affected. The interference data can also be associated with an interference signature (e.g., an interference pattern, a fingerprint) for an interference source in a database. The database can be used based on the interference signature to identify known and/or unknown interference sources.

  • Patent number: 11228474
    Abstract: A method of recovering information encoded by a modulated sinusoidal waveform having first, second, third and fourth data notches at respective phase angles, where a power of the modulated sinusoidal waveform is reduced relative to a power of an unmodulated sinusoidal waveform within selected ones of the first, second, third and fourth data notches so as to encode input digital data. The method includes receiving the modulated sinusoidal waveform and generating digital values representing the modulated sinusoidal waveform. A digital representation of the unmodulated sinusoidal waveform is subtracted from the digital values in order to generate a received digital data sequence, which includes digital data notch values representative of the amplitude of the modulated sinusoidal waveform within the first, second, third and fourth data notches. The input digital data is then estimated based upon the digital data notch values.

  • Patent number: 11206560
    Abstract: A wireless relay mitigates cross-relay interference when serving wireless user devices. A network transceiver detects wireless access points and determines signal strengths for the wireless access points. The network transceiver transmits test signals to the wireless access points and directs a user transceiver to detect interference levels during the test. The network transceiver uses the interference level reported by user transceiver to calculate the interference level it would receive from the transmitter of user transceiver with a certain algorithm. The network transceiver selects wireless access points based on their signal strength and calculated cross-relay interference levels. The network transceiver exchanges user data with the selected wireless access points. The user transceiver exchanges the user data with the wireless user devices.
