A method according to an embodiment includes receiving UWB data indicative of a distance of a mobile device relative to the access control device and a SNR of signals received by a plurality of UWB antennas, inferring a side of the passageway at which the mobile device is located based on the distance of the mobile device relative to the access control device and also based on the SNR of the signals, estimating a travel time of the mobile device to the passageway based on the UWB data if the inferred side of the passageway based on the distance of the mobile device is different from the side of the passageway inferred based on the SNR of the signals, and determining the side of the passageway at which the mobile device is located to be an unsecure side of the passageway if the travel time exceeds a predefined threshold time.

The present disclosure provides a service beginning using a UWB OWR, and a user gesture input method. A method of an ultra-wide band (UWB) device, according to various embodiments of the present disclosure, comprises the steps of: receiving, from a second UWB device, a first UWB advertisement message for measurement of an angle of arrival (AoA) with a third UWB device, the UWB advertisement message being a message for UWB one-way ranging (OWR) and including information about a transmission period of the UWB advertisement message; and determining, on the basis of the information about the transmission period, a mode for identifying a user gesture input of the first UWB device, wherein the mode for identifying the user gesture input can be one of a first mode using the UWB OWR in order to identify the user gesture input and a second mode using both the UWB OWR and UWB two-way ranging (TWR) with the third UWB device in order to identify the user gesture input.

A position of a first entity of a wireless communication network is determined on the basis of one or more measurements between the first entity and a second entity. For one of the measurements, a reference signal is transmitted between the first and the second entities. The first and the second entities use respective antenna patterns for transmitting or receiving the reference signal. The position of the first entity is determined using antenna pattern information about the antenna pattern used by the first entity and/or antenna pattern information about the antenna pattern used by the second entity.

In an aspect, a first network entity may engage in a positioning session with a second network entity. The first network entity may determine that a plurality of positioning errors associated with a corresponding plurality of positioning error causes occurred during the positioning session. The first network entity may report a positioning error cause of a positioning error of the plurality of positioning errors to the second network entity during the positioning session based on priorities assigned to the plurality of positioning error causes.
