Abstract

According to the reference signal configuration and positioning method and a device, and a storage medium, each network element in the management range of the positioning server determines available TRS sending resources which can be used for sending the TRS at present, and sends the available TRS sending resources to the positioning server; the positioning server respectively receives the available TRS sending resources sent by each network element, determines TRS suggestion configuration information in combination with the available TRS sending resources of each network element, and then sends the TRS suggestion configuration information to each network element; each network element configures a TRS resource for sending the TRS based on the TRS suggestion configuration information; and the UE performs TRS detection according to the TRS suggestion configuration information sent by the positioning server or each network element so as to determine the position of the UE. Under the condition that the system complexity is not obviously increased, the existing reference signal mechanism is adjusted, the audibility of the reference signal is improved, and the positioning accuracy is improved.

Description

technical field

[0001] Embodiments of the present invention relate to but are not limited to the field of communication, and specifically, relate to but are not limited to a reference signal configuration and positioning method, device, and storage medium. Background technique

[0002] Location requirements from business services and emergency call management drive the development of location in wireless networks. The 3rd Generation Partnership Project Long Term Evolution (3GPP LTE) has introduced support for positioning since release 9.

[0003] The Global Positioning System (GPS) can well support the needs of outdoor positioning, but in places where some indoor and outdoor satellite signals are blocked, the effect of GPS positioning will be seriously affected. Such scenarios require other localization methods. Since release 9, 3GPP has introduced a positioning method based on observed time difference of arrival (OTDOA, Observed Time Difference of Arrival) of downlink sig...

Embodiment 1

[0056] In order to solve the technical problem of low positioning accuracy caused by the relatively limited audibility of reference signals used in related technologies for positioning, an embodiment of the present invention provides a reference signal configuration method. This embodiment provides The reference signal configuration method is applied to the NE side, see figure 1 shown, including:

[0057] S101. Determine currently available TRS transmission resources that are currently available for sending TRS.

[0058] Wherein, the network element determines the resources currently available for sending a tracking reference signal (TRS, CSI-RS for tracking) according to its own current channel and resource allocation of reference signals. As an implementation of this embodiment, TRS can be used The sending resource is a resource that can be used to send the TRS in the whole frequency band of the network element.

[0059] Optionally, available TRS transmission resources inc...

[0080] S301. Respectively receive available TRS transmission resources sent by network elements within a preset management range; the TRS transmission resources are used for network elements to transmit TRS.

[0081] In the embodiment of the present invention, the network element determines the resources currently available for sending TRS according to its current resource allocation of each channel and reference signal. As an implementation of this embodiment, the available TRS sending resources are A resource for transmitting TRS in a frequency band. ...

Embodiment 3

[0093] In order to better understand the present invention, this embodiment uses several specific examples to describe the reference signal configuration method in detail.

[0094] In one implementation of this embodiment, as Figure 4 Shown is a schematic diagram of available resources of network elements provided by this embodiment, wherein, Figure 4 a is network element a i A schematic diagram of available resources, Figure 4 b is network element b i A map of available resources. Assume that the frequency band of the network elements managed by a positioning server is below 3Ghz, the bandwidth of all network elements is 50Mhz, half of the network elements a i SSB is sent at 30Khz subcarrier intervals, the SSB sending cycle is 5ms, the SSB sending mode is case C, and the number of SSBs sent in one cycle is 4. The other half of the network element b i SSB is sent at 30Khz subcarrier intervals, the SSB sending cycle is 5ms, the number of SSBs sent in one cycle is 2, an...
