Embodiment Construction

[0028] The principles of the disclosure will now be described with reference to some example embodiments. It should be understood that these embodiments are only described to illustrate and help those skilled in the art to understand and implement the present disclosure, without implying any limitation on the scope of the present disclosure. The disclosure described herein can be implemented in various ways other than those described below.

[0029] In the following description and claims, unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.

[0030] As used herein, the term "base station" (BS) refers to a device via which user equipment (UE) can access a communication network. Examples of base stations include Relay, Access Point (AP), Transmission Point (TRP), Node B (NodeB or NB), Evolved NodeB (eNodeB or eNB), New Radio (NR) NodeB (gNB), R...

Abstract

The embodiment of the invention relates to a packet-based positioning reference signal (PRS) resource mapping and configuration method and device and a computer readable storage medium. In an example embodiment, a location server determines a set of neighboring base stations based on geographic locations of the base stations. A location server allocates at least one time domain resource and a set of frequency domain resources for a set of PRSs to be transmitted by a set of neighboring base stations. The location server also sends an indication to a set of neighboring base stations indicating at least one time domain resource and a set of frequency domain resources.

Description

technical field [0001] The embodiments of the present invention generally relate to the communication field, and in particular, relate to a method, device, and computer-readable storage medium for packet-based positioning reference signal (PRS) resource mapping and configuration. Background technique [0002] Observed Time Difference of Arrival (OTDOA) is a downlink positioning technique in Long Term Evolution (LTE) Release 9 (Rel-9). This technology employs a multipoint measurement method in which a user equipment (UE) measures the time of arrival (TOA) of signals received from multiple base stations (eg, eNBs). In LTE, Positioning Reference Signals (PRS) have been introduced to allow UEs to make proper timing measurements of signals from base stations, thereby improving OTDOA positioning performance. [0003] A positioning technique for a New Radio (NR) system is being developed in the 3rd Generation Partnership Project (3GPP) standardization. Positioning technology need...
