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...
Embodiment 2
[0079] 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 positioning server side, please refer to image 3 shown, including:
[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...
