The following first describes the communication terms relevant to the present application in brief.

(1) New Radio (NR) positioning standardization progress

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

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

2) The positioning reference signals (Positioning Reference Signal, PRS) may be from a plurality of transmission and reception points (Transmission Reception Point, TRP), and the plurality of TRPs may be from a serving cell or a non-serving cell. The UE measures PRSs of a plurality of TRPs, and then performs positioning measurement reporting or positioning calculation.

3) PRS supports transmission at FR1 max 100M and FR2 max 400M. The NR PRS Bandwidth configuration is independent of a Bandwidth Part (BWP) configuration, and when the PRS Bandwidth is greater than the BWP Bandwidth, a supporting User Equipment (UE) uses a Measurement Gap to measure PRS.

4) PRS supports beamforming, thus introducing the concept of PRS resources (resources). The PRS resource ID may correspond to 1 beam of 1 TRP. 1 or more PRS resources may constitute 1 PRS resource set (resource set), or 1 or more PRS resources may be contained within 1 PRS resource set. One TRP may contain 1 or more PRS resources. Meanwhile, PRS beam scanning and PRS beam repetition are supported in order to increase the audibility of the UE. In addition, PRS reference neighbor cell reference signals (Reference Signals, RS) are supported as spatially Quasi Co-located (QCL) reference signals.

5) PRSs support interleaved patterns (patterns) and support flexible pattern configurations. Comb structures of PRS resources can support {2,4,6,12}; the number of symbols (symbols) may support {2,4,6,12}. The currently supported combinations of symbol numbers and comb size are shown in table 1:

TABLE 1

	2symbols	4symbols	6symbols	12symbols
					Comb-2	{0,1}	{0,1,0,1}	{0,1,0,1,0,1}	{0,1,0,1,0,1,0,1,0,1,0,1}
Comb-4	NA	{0,2,1,3}	NA	{0,2,1,3,0,2,1,3,0,2,1,3}}
					Comb-6	NA	NA	{0,3,1,4,2,5}	{0,3,1,4,2,5,0,3,1,4,2,5}
Comb-12	NA	NA	NA	{0,6,3,9,1,7,4,10,2,8,5,11}

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

(2) PRS ports

Long term evolution (Long Term Evolution, LTE) supports PRS transmissions for only a single port, NR Rel-16 positioning discusses whether single port and dual port PRS transmissions are supported. But since two-port PRS will introduce more resource overhead and there is not enough demonstration, finally Rel-16 passes only PRS supporting a single port.

(3) PRS sequences

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

wherein the pseudo-random sequence c (i) is defined in section 5.2.1. The pseudo-random sequence generator should be initialized to:

wherein,,

for time slot number, downlink PRS sequence ID +.>

Given by the higher layer parameter dl-PRS-sequence id, l is the OFDM symbol within the slot to which the sequence is mapped.

The PRS sequence is Gold sequence and is obtained by quadrature phase shift keying (Quadrature Phase Shift Keying, QPSK) modulation. Wherein the initialization function of the Gold sequence is c _init Its design requires distinguishing PRSs for each TRP, maintaining interference randomization and good sequence cross correlation properties between DL PRSs for each TRP.

(4) PRS mapping

For each downlink PRS resource configured, the UE shall assume that the sequence r (m) is factored by β _PRS Scaled and mapped to resource units (k, l) according to the following equation _p，μ ：

m＝0,1,…

When the following condition is satisfied:

resource unit (k, l) _p,μ Is positioned in a resource block occupied by a downlink PRS resource for which the UE is configured;

symbol l is not used by any synchronization signal/physical broadcast channel block (SS/PBCH) blocks used by the serving cell for downlink PRS transmitted from the same serving cell or by any SS/PBCH blocks of non-serving cells, the time-frequency position of which is provided by higher layers to the UE for downlink PRS transmitted from the same non-serving cell;

the slot number satisfies the condition 7.4.1.7.4 in clause 7.4.

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

The CSI-RS of the multiple ports may be divided into different code division multiplexing (Code Domain Multiplexing, CDM) groups, wherein the CSI-RS time-frequency positions of the different CDM groups may be different; one CDM group occupies time-domain and/or frequency-domain continuous Resource Element (RE) positions, and different ports in one CDM group are distinguished by frequency-domain orthogonal codes (FD-OCCs) and/or time-domain orthogonal codes (TD-OCCs), occupy the same time-domain and frequency-domain positions, 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 within the radio frame, is the OFDM symbol number within the slot, and is equal to the higher layer parameter scramblingID or sequence generation config.

(7) CSI-RS mapping

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

n＝0，1，...

when the following condition is satisfied:

resource unit (k, l) _p,μ The reference point of k=0 within 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 higher layer parameters in the CSI-RS-ResourceMapping IE or CSI-RS-CellMobility IE and the port number X is given by the higher layer parameter nrofPorts.

1) A port number N;

for example, the port number may support at least one of 1,2,4,6,8,16,32,64.

3) Positioning a reference signal port group;

4) Port location identification.

In this embodiment, optionally, the positioning reference signal ports identified by different positions are not co-located, and the positioning reference signal ports identified by the same position are co-located.

The configuration of the positioning reference signal port group is explained below.

In this embodiment, optionally, each of the positioning reference signal port groups includes at least one positioning reference signal port.

In this embodiment, optionally, the configuration information of the positioning reference signal port group includes at least one of the following: the number of positioning reference signal port groups, the positioning reference signal port group index, the number of positioning reference signal ports within a positioning reference signal port group, the positioning reference signal port index within a positioning reference signal port group, the positioning reference signal port group location (or co-location) identification, the CDM port group number within a positioning reference signal port group, the CDM port group index within a positioning reference signal port group, the positioning reference signal port number within a CDM port group, the positioning reference signal port index within a CDM port group.

Alternatively, if the positioning reference signal port group includes 1 CDM port group, the positioning reference signal port group is equivalent to the CDM port group (i.e., only one concept of positioning reference signal port group or CDM port group appears).

Alternatively, if the CDM port group includes 1 positioning reference signal port, the CDM port group is equivalent to the positioning reference signal port.

In this embodiment, optionally, each positioning reference signal port group corresponds to a respective positioning reference signal port group index.

In other words, the receiving node either jointly processes the measurement results of the position reference signal ports of the same position reference signal port group, or allows joint processing for co-located position reference signals, according to protocol conventions or other node indications.

Optionally, the receiving node does not want to jointly process measurements of the positioning reference signal ports from different positioning reference signal port groups, or does not want to jointly process measurements of non-co-located positioning reference signal ports (or positioning reference signal port groups or CDM port groups), or does not want to jointly process measurements of positioning reference signal ports from different positioning reference signal CDM port groups.
