This specification describes a method comprising causing a trackable device to transition between a first positioning mode and a second positioning mode, wherein, in the first positioning mode, the trackable device causes wireless transmission of one or more data packets each including a data portion for enabling determination of a bearing between the trackable device and a locator device and, in the second positioning mode, the trackable device causes wireless transmission of one or more data packets which do not include the data portion for enabling determination of the bearing between the trackable device and the locator device.

An antenna apparatus for use in a wireless network and method of operating such an antenna apparatus are provided. The antenna apparatus has omnidirectional antenna elements and RF chains, where there are fewer RF chains than omnidirectional antenna elements. A subset of the omnidirectional antenna elements are coupled to the RF chains and sampling circuitry coupled to the RF chains samples the signals received by the subset of the omnidirectional antenna elements. This forms part of a signal detection process in which different subsets of the omnidirectional antenna elements are iteratively coupled to the RF chains. A signal sample spatial covariance matrix for the omnidirectional antenna elements is constructed from the signals sampled by the sampling circuitry at each iteration and a beamforming algorithm applied to the signal sample spatial covariance matrix parameterizes the signals received by the omnidirectional antenna elements.

A method of direction finding (DF) positioning involving main lobe and grating lobe identification in a wireless communication network is proposed. A receiver performs DF algorithm on radio signals associated with multiple antennas over a first channel frequency and estimates a first set of DF solutions. The receiver performs DF algorithm on radio signals associated with multiple antennas over a second channel frequency and estimates a second set of DF solutions. The receiver then identifies the correct DF solution (e.g., the main lobe direction) by comparing the first set of DF solutions and the second set of DF solutions.

The disclosure relates to technology for iterative localization and channel estimation in a communication system. A radio network node detects user location information from user equipment in a geographic region, where the geographic region includes a location cluster having multiple location levels. A location signature profile is formed for each level based on the location signature of a corresponding location level in the cluster, and a filter is generated for each level based on the location signature. Upon application of the filter that matches the location level of the location user information, the channel is estimated and the user location information is updated based on the channel estimation. The process is repeated until the user location information converges with a preselected convergence value.

An angle-of-arrival antenna system uses two orthogonal arrays of patch antenna elements to measure the angle of arrival of a wireless signal irrespective of its polarization. Each antenna element has an antenna patch located over a corresponding ground patch. A shorting wall directly electrically connects one edge of the antenna patch to a corresponding edge of the underlying ground patch. The edge of the ground patch is also directly connected to a system ground plane. No other edges of the ground patch are connected to the system ground plane. The shorting wall acts as an impedance that isolates the ground patch from the system ground plane, and therefore improves isolation between the antenna elements. The antenna system may be constructed using conventional circuit-board fabrication techniques by implementing each shorting wall as an array of plated through-holes or slots.
