Problems solved by technology

Therefore, if the receiver is performing a task that requires precise timing measurements, and the beam with the highest received signal strength is subject to longer propagation delays, then the beam with the highest received signal strength may not be optimal for the task at hand

Abstract

Positioning methods suitable for use in a wireless network that utilizes beamformed communication are disclosed. In an aspect, a range and / or granularity for reporting a reference signal timing difference (RSTD) may be configurable according to one or more beam parameters (e.g., a repetition factor, a beam shape, a frequency band, a subcarrier spacing numerology, a cyclic prefix, etc.). In anotheraspect, a transmitting node may transmit one or more parameters associated with a beam used to transmit a positioning reference signal (e.g., an angle of departure, a zenith of departure, a beamwidth, etc.). According to another aspect, a cyclic prefix length for a positioning reference signal that a transmitting node transmits via one or more beams may be configured to increase a number of neighbor cells visible to a receiving node.
