Apparatus and methods are presented for synchronising a slave device signal to a reference timebase, in situations where the slave device lacks knowledge of the propagation delay for signals from the reference device, e.g. if the positions of one or both of the devices are unknown or classified, or the inter-device signal propagation distance is otherwise a-priori unknown. Reference signal propagation delay is determined using an exchange of signals between the devices, with each device using a differencing procedure for eliminating effects of receiver line bias and other hardware delays. In another aspect an exchange of signals between the devices is used to detect a time residual arising from an inaccurate propagation delay estimate. The synchronisation methods can be applied to a plurality of slave devices for providing a synchronised location network. In certain embodiments signals are transmitted wirelessly, while in other embodiments they are transmitted via a fixed line.

Methods and systems are described which use a sensing system in cooperation with a wireless communication system. Coordinate information (which may be from the sensing system, from an electronic device, or from a network-side device) and signal-related information (which may be from the wireless system) are associated with each other. The associated information may be used for wireless communication management, such as beam management operations, among others.

The invention relates to an antenna soft switching system of an Angle of Departure, AoD, direction finding transmitter unit. The soft switching system comprises: a timing unit for obtaining at least a starting time of a switching event, a switching network arranged on a radio frequency, RF, signal path between an RF port and a first antenna port and a second antenna port, and a generator unit for generating at least one waveform for controlling the switching network. The generator unit is configured to control the switching network so that the amplitude of the RF signal is switched substantially smoothly from the first antenna port to the second antenna port so that level of unwanted emissions of a transmitted RF spectrum of the AoD directional finding transmitter unit are reduced. The invention relates also to an AoD direction finding transmitter unit comprising the antenna soft switching system and to an antenna soft switching method for an AoD directional finding transmitter unit.

One variation of a method includes: defining a first capacitance gradient of capacitance thresholds spanning a capacitive touch sensor; defining a first pressure gradient of pressure thresholds spanning a pressure sensor; reading a capacitance value from the capacitive touch sensor proximal a first location; detecting presence of a first input at the first location in response to the capacitance value exceeding a capacitance threshold assigned to the first location; reading a pressure value from the pressure sensor proximal the first location; detecting presence of a second input proximal the first location in response to the pressure value exceeding a pressure threshold; in response to detecting the first input and detecting the second input: merging the first input and the second input into a confirmed touch input; and generating a first touch image representing the first location and the pressure value of the confirmed touch input.

Systems and methods determine a position using uncoordinated signals containing timing information. The systems and methods use uncoordinated signals of opportunity, such as radio time signals, to determine a position of a receiver by determining the relative synchronization of the signals of opportunity at a known location and, at a later time and unknown locations, using trilateration or multilateration of the signals of opportunity to determine the position of the receiver.

A radio frequency connection between a far field voice detection device and a further device is used to determine a first angular direction from the far field voice detection device to the further device. The determined first angular direction is then used to emphasize, during a noise processing of a plurality of sounds received via use of a plurality of microphones of the far field voice detection device, a first one of the plurality of sounds relative to a remainder of the plurality of sounds.

An ultra-wideband (“UWB”) communication system comprising a transmitter having two transmit antennas and a receiver having a single receive antenna. Respective selected portions of the UWB signal are transmitted by the transmitter via each of transmit antennas is received at the receive antenna. By comparing the phases of the received signal portions, the phase difference of departure can be determined. From this phase difference and the known distance, d, between the transmit antennas, the Cartesian (x,y) location of the transmitter relative to the receiver can be directly determined.

The method includes: A terminal device receives configuration information from the network device, where the configuration information includes reference signal configuration information and information about an association between N sets of frequency information and M sets of beam information. Then, the terminal device receives a reference signal corresponding to the reference signal configuration information, to obtain a measurement result, where the measurement result is obtained by measuring the reference signal based on an association relationship between frequency information and beam information. Finally, the terminal device reports the measurement result to the network device.
