Methods and systems related to the field of pointing devices are disclosed herein. A pointing device having a pointing direction can include at least two antennas aligned with the pointing direction. A pointing target can include at least one antenna that can transmit a signal to be received by the at least two antennas in the pointing device. A difference of the signal as received by each of the at least two antennas in the pointing device can be determined. An angle between the pointing direction and the pointing target can be determined using the difference.

An apparatus includes an antenna and a transceiver. The transceiver transmits a first signal via the antenna, the first signal including a unique identification of the apparatus and a request for receive information about the first signal at a receiver. The transceiver receives from the receiver a second signal via the antenna, the second signal including first information about a direction of arrival (DoA) of the first signal at the receiver and second information indicative of a location of the receiver.

A method for signal processing includes receiving at a given location at least first and second signals transmitted respectively from at least first and second antennas (34) of a wireless transmitter (24). The at least first and second signals encode identical data using a multi-carrier encoding scheme with a predefined cyclic delay between the transmitted signals. The received first and second signals are processed, using the cyclic delay, in order to derive a measure of a phase delay between the first and second signals. Based on the measure of the phase delay, an angle of departure (θ) of the first and second signals from the wireless transmitter to the given location is estimated.

A beacon network includes a plurality of beacons arranged at predetermined positions to periodically or intermittently emit a signal wave including identification information, and a radio wave absorber to adjust an emission angle of the signal wave emitted from at least one of the plurality of beacons.

A wireless communications device (100) includes a wireless interface (122) for conducting wireless communications with one or more network nodes (110) of a wireless communications network (102). The wireless communications device (100) further includes a control circuit (118) configured to receive a plurality of reference signals transmitted by the one or more network nodes (110), measure the plurality of reference signals to generate a plurality of positioning measurements, associate the plurality of positioning measurements with beam information, and select a set of positioning measurements with associated beam information for determining a positioning estimate of the wireless communications device (100).

The present application relates to devices and components including apparatus, systems, and methods for enhanced angle-based positioning calculations.

The position of a mobile device is estimated using angle based positioning measurements. The angle based positioning measurements are generated using transmit (Tx) beams or receive (Rx) beams from one or more base stations that generate the beams over an ultra-wide bandwidth, which produces frequency and spatial distortions and impairments in an array gain response. The array gain distribution variation as a function of angle and frequency for the set of beam weights used in beamforming is conveyed to indicate the frequency and spatial distortions. The array gain distribution variation may be provided to the mobile device in assistance data for a sub-band that is only a portion of the allocated bandwidth for the base stations, or as an aggregation of the array gain distribution variation for a plurality of sub-bands of the allocated bandwidth to reduce the overhead in signaling.
