The communication terms related to this application will be briefly introduced below.

(1) New Radio (NR) Positioning Standardization Progress

NR redesigned the downlink positioning reference signal NR DL PRS based on the NR system, including the following:

1) In the current protocol, the positioning reference signal only supports a single port.

2) Positioning Reference Signal (PRS) can come from multiple transmission and reception points (Transmission Reception Point, TRP), and multiple TRPs can come from serving cells or non-serving cells. The UE measures the PRSs of multiple TRPs, and then performs positioning measurement reporting or positioning calculation.

3) PRS supports transmission in frequency range 1 (Frequency range 1, FR1) up to 100M and FR2 up to 400M. NR PRS bandwidth configuration has nothing to do with the bandwidth part (Bandwidth Part, BWP) configuration. When the PRS bandwidth is greater than the BWP bandwidth, the user equipment (User Equipment, UE) is supported to use the measurement gap (Measurement Gap) to measure the PRS.

4) PRS supports beamforming, so the concept of PRS resource (resource) is introduced. The PRS resource ID can correspond to 1 beam in 1 TRP. One or more PRS resources can form a PRS resource set (resource set), or a PRS resource set can contain one or more PRS resources. A TRP can contain one or more PRS resources. At the same time, in order to increase the audibility of the UE, PRS beam scanning and PRS beam repetition are supported. In addition, PRS is supported to refer to adjacent cell Reference Signals (Reference Signals, RS) as spatial quasi-co-location (Quasi Co-Location, QCL) reference signals.

5) PRS supports staggered patterns and supports flexible pattern configuration. The comb structure of PRS resource can support {2,4,6,12}; the number of symbols can support {2,4,6,12}. The currently supported combination of symbol number and comb size (size) is shown in Table 1:

Table 1

Typical PRS patterns under different comb structures are shown in Figure 2.

(2) PRS port

Long Term Evolution (LTE) only supports single-port PRS transmission, and NR version 16 (Release16, Rel-16) discusses whether to support single-port and two-port PRS transmission. However, because the two-port PRS will introduce more resource overhead, and there is not enough argumentation, in the end Rel-16 only supports the single-port PRS.

(3) PRS sequence

The UE shall assume that the reference signal sequence r(m) is defined as:

where the pseudo-random sequence c(i) is defined in Section 5.2.1. The pseudorandom sequence generator should be initialized as:

in,

is the slot number, downlink PRS sequence ID

Given by the high layer parameter dl-PRS-SequenceID, l is an Orthogonal frequency division multiplex (Orthogonal frequency division multiplex, OFDM) symbol in the time slot to which the sequence is mapped.

The PRS sequence is a Gold sequence and is obtained by performing quadrature phase shift keying (Quadrature Phase Shift Keying, QPSK) modulation. Among them, the initialization function of the Gold sequence is c _init , and its design requires distinguishing the PRS of each TRP, and maintaining the interference randomization and good sequence cross-correlation characteristics between the DL PRS of each TRP.

(4) PRS mapping

For each downlink PRS resource configured, the UE shall assume that the sequence r(m) is scaled with a factor β _PRS and mapped to resource elements (k,l) _p,μ according to the following equation:

When the following conditions are met:

The resource unit (k, l) _{p, μ} is located in the resource block occupied by the downlink PRS resource for which the UE is configured;

Symbol l is not used by the serving cell for any Synchronization Signal (SS)/Physical broadcast channel (PBCH) block of downlink PRS transmitted from the same serving cell or any SS/PBCH of a non-serving cell Block usage, whose time-frequency location is provided by higher layers to the UE for downlink PRS transmitted from the same non-serving cell;

The slot number satisfies condition 7.4.1.7.4 in clause 7.4.

(5) Multi-port channel state information reference signal (Channel State Information Reference Signal, CSI-RS) design

The CSI-RS of multiple ports can be divided into different code division multiplexing (Code Domain Multiplexing, CDM) groups (groups), wherein the CSI-RS time-frequency positions of different CDM groups can be different; a CDM group occupies the time domain and /or continuous resource element (Resource Element, RE) position in the frequency domain, and different ports in a CDM group pass the frequency domain orthogonal code (Frequency Division Orthogonal Cover Code, FD-OCC) and/or the time domain orthogonal code ( Time Division Orthogonal Cover Code, TD-OCC) distinction, occupying the same time domain and frequency domain position, please refer to Table 2:

Table 2

(6) CSI-RS sequence design

The UE shall assume that the reference signal sequence r(m) is defined as:

At the beginning of each OFDM symbol, where

is the slot number in the radio frame, is the OFDM symbol number in the slot, and is equal to the high-level parameter scramblingID or sequenceGenerationConfig.

(7) CSI-RS mapping

For each configured CSI-RS, the UE shall assume that the sequence r(m) is mapped to resource elements (k,l) _p,μ according to:

When the following conditions are met:

The reference point of resource unit (k, l) _{p, μ} with k=0 in the resource block occupied by the CSI-RS resource configured by the UE is subcarrier 0 in common resource block 0. The value of ρ is given by the high-level parameter in CSI-RS-ResourceMapping IE or CSI-RS-CellMobility IE, and the number of ports X is given by the high-level parameter nrofPorts.
