SCALABILITY OF LOCATION IN THE CLOUD WITH ANGLE OF ARRIVAL (AOA) SEARCH ON THE EDGE

Determining a device's location in a space in real time is computing intensive. To offload some of the workload in conducting this hyperlocation, the access points in the network conduct some of process in determining the location of a device. The cloud determines a restricted AoA search area based on previous client locations. After this determination, a three-dimensional (3D) AoA search is conducted by each AP in the restricted area (restricted by a range of azimuth directions) for a device. Finally, each AP reports a location(s) for the device, which comprises weights for selected angular sectors. The cloud can then construct a probability heat map for location computation from the weights provided from each AP for the device.

TIME-DOMAIN WAVEFORM REPORTING FOR POSITIONING

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may report measurements of a signal transmitted by a base station via a waveform. Based on the waveform, the base station may determine a position of the UE. The UE may measure the signal in a frequency band, where additional signaling in an adjacent frequency band causes interference on the signal. The UE may determine characteristics for measuring the signal based on the interference and may generate samples of the signal based on the measurement characteristics. Additionally, the UE may identify one or more antennas for measuring the signal and generate the samples based on the identified antennas. The UE may transmit the waveform report to the base station based on the samples. In some cases, the waveform may be based on a fractional symbol reporting scheme or a time mask with an offset and sampling rate.
