Embodiment approach

[0056] As an optional implementation manner, the determining the resource location of the PRS in the BWP includes:

[0057] Determine the initial common resource block (common resource block, CRB) index of the PRS resource in the BWP, and the bandwidth of the PRS resource in the BWP.

[0058] The starting PRB position of the above PRS resource may be expressed as: the RB offset of the lowest PRB of the PRS resource relative to common resource block 0 (CRB#0). The number of PRBs occupied by the PRS resource can be expressed as: the number of PRBs across which this PRS resource spans (Number of PRBs across which this PRS resource spans).

[0059] Further, when the index of the starting PRB position is smaller than the starting PRB index of the BWP, the index of the initial CRB is the starting PRB index of the BWP; or

[0060] In the case that the index of the starting PRB position is greater than or equal to the starting PRB index of the BWP, the index of the initial CRB is the...

Embodiment 1

[0173] The position of the PRS resource in the common resource block grid (common resource block grid) may be determined by the starting PRB position (startingRB) of the PRS resource and the number of PRBs occupied by the PRS (nrofRBs). The starting PRB position of the PRS resource is the RB offset of the lowest PRB of the PRS resource relative to (CRB#0). The number of PRBs occupied by the PRS resource is the number of PRBs across which this PRS resource spans (Number of PRBs across which this PRS resource spans).

[0174] Specifically, the frequency domain granularity of PRS resources can be 1RB, 2RB, 4RB or 8RB

[0175] If the frequency domain granularity of the PRS resource is 1RB, the starting PRB position of the PRS resource can be (0,1,2,3..275*8-1), and the unit is RB; the number of PRBs occupied by the PRS can be ( Xmin, Xmin+1, Xmin+2...Xmax). Xmin can take one of 1, 11, 12, 24 or 25, and Xmax can take one of 264, 272, 273, 275 or 2200.

[0176]If the frequency do...

Embodiment 2

[0184] This embodiment provides the behavior of the terminal determining the bandwidth for receiving the PRS in the frequency domain within the BWP when the measurement gap is not configured.

[0185] When the starting PRB position of the PRS resource The lowest CRB index of the PRS resource that the terminal can measure Otherwise, the terminal assumes that N initial RB =startingRB.

[0186] like If the number of PRBs occupied by the PRS resource Then the bandwidth of the PRS resource that the UE can measure is otherwise like If the number of PRBs occupied by the PRS resource Then the bandwidth of the PRS resource that the UE can measure is );otherwise

[0187] like Then the terminal does not perform measurement on the PRS resource.

[0188] The terminal behavior may be specified by an instruction on the network side or by a protocol.

Abstract

An embodiment of the present invention provides a PRS resource configuration method, a measurement interval configuration method, and related equipment. The method includes: determining the resource location of the PRS in the BWP according to the starting PRB location and the number of PRBs of the PRS resource; Perform measurements. The embodiment of the present invention can improve the probability that the terminal measures the PRS.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a positioning reference signal (Positioning Reference Signal, PRS) resource configuration method, a measurement interval configuration method and related equipment. Background technique [0002] In the positioning technology, the terminal can measure the positioning reference signal (Positioning Reference Signal, PRS) sent from multiple cells or multiple transmission points, so as to obtain the reference signal time difference (Reference Signal) between multiple cells or multiple transmission points. Time Difference, RSTD) and Reference Signal Received Power (Reference Signal Receiving Power, RSRP), and then send the measured result to the network side for positioning. Since the bandwidth part (BWP) is not supported in the target positioning technology, if the current positioning technology is adopted, there will be a problem that the probability of the terminal me...
