摘要： Unmanned aerial vehicle drive testing and mapping of carrier signals is disclosed. An example method may include determining that an unmanned aerial vehicle is travelling on a flight route at an altitude for determination of network performance of a cellular network. The method may further include determining, using an antenna, signal diagnostics of the cellular network during travel of the unmanned aerial vehicle on the flight route. The method may conclude with transmitting the signal diagnostics of the cellular network to a service provider.

摘要： Systems and methods are described herein for communications bandwidth enhancement using Orthogonal Spatial Division Multiplexing (OSDM). For example, large sparse antenna arrays may be able to distinguish between signals emitted by multiple nearly collocated antennas, even if the signals have the same frequency, polarization, and coverage. Thus, the use of a large sparse antenna array may be able to resolve/isolate individual antennas on a single platform, allowing for OSDM, analogous to Orthogonal Frequency Divisional Multiplexing (OFDM). Using OSDM, multiple antennas on the same vehicle are able to reuse the same frequencies/polarizations without interference, thereby increasing spectrum availability while still providing the same transmitter power spectral density and total RF power emission.

摘要： In this invention, we disclose methods for enabling ad hoc cellular base station functionality within a user equipment when the connection quality between a base station and the user equipment is limited or nonexistent. These methods include measuring a connection quality between a user equipment and its serving base station. If the connection quality is below a threshold, the user equipment can enable its internal ad hoc cellular base station functionality. This is done by running a software within the user equipment that (a) checks the connection quality periodically, and (b) enables ad hoc cellular base station functionality of the connection threshold dips below a certain value. In one embodiment, that threshold could be the same threshold value that a user equipment would use if it were making a decision to handoff to another base station based on poor connection quality.

摘要： Representative implementations of devices and techniques provide communication between networked nodes operating on a communication network medium. In an implementation, a node generates a broadcast frame that includes at least a preamble and a payload. The preamble of the broadcast frame may include auxiliary information. The auxiliary information may be associated with one or more symbols of the preamble. The auxiliary information may contain power boost information.

摘要： A user equipment device (UE) reduces receive beam selection time. An antenna array forms receive beams to receive synchronization signal blocks (SSBs) transmitted by a base station (BS). Each SSB comprises OFDM symbols. Each SSB includes a BS-assigned index. The receive beams are switched in time such that, for each SSB, two or more of the receive beams are used to receive corresponding two or more mutually exclusive sets each having at least one but less than all of the OFDM symbols of the SSB. A processor is programmed to, for each receive beam/SSB index pair, measure a signal quality based on the at least one but less than all of the OFDM symbols of the indexed SSB received by the receive beam of the pair. The processor uses the measured signal qualities to select one of the receive beams to use to receive subsequent communications from the BS.
