[0037] The following is a brief introduction to the communication terms related to this application.

[0038] (1) Progress in New Radio (NR) positioning standardization

[0039] NR has redesigned the downlink positioning reference signal NR DL PRS based on the NR system, including the following:

[0040] 1) In the current protocol, the positioning reference signal only supports a single port.

[0041] 2) The Positioning Reference Signal (PRS) can come from multiple Transmission Reception Points (TRPs), which can originate from the serving cell or non-serving cells. The UE measures the PRS of multiple TRPs and then performs positioning measurement reporting or positioning calculation.

[0042] 3) PRS supports transmission up to 100 Mbps in FR1 and up to 400 Mbps in FR2. NR PRS bandwidth configuration is independent of the Bandwidth Part (BWP) configuration. When the PRS bandwidth is greater than the BWP bandwidth, the User Equipment (UE) is supported in using the Measurement Gap to measure the PRS.

[0043] 4) PRS supports beamforming, thus introducing the concept of PRS resources. A PRS resource ID can correspond to one beam in a TRP. One or more PRS resources can form a PRS resource set, or a PRS resource set can contain one or more PRS resources. A TRP can contain one or more PRS resources. Furthermore, to improve UE audibility, PRS beam scanning and PRS beam repetition are supported. Additionally, PRS reference neighbor signals (RS) are supported as quasi-co-location (QCL) reference signals.

[0044] 5) PRS supports interleaved patterns and flexible pattern configuration. The PRS resource comb structure can support {2, 4, 6, 12}; the number of symbols can support {2, 4, 6, 12}. The currently supported combinations of symbol number and comb size are shown in Table 1.

[0045] Table 1

[0046] 2 symbols 4 symbols 6 symbols 12 symbols 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}

[0047] Typical PRS patterns under different comb structures are as follows: Figure 2 As shown.

[0048] (2) PRS port

[0049] Long Term Evolution (LTE) only supports single-port PRS transmission. NR Rel-16 discussed whether to support single-port and two-port PRS transmission. However, since two-port PRS would introduce more resource overhead and there was insufficient justification, Rel-16 ultimately only approved support for single-port PRS.

[0050] (3) PRS sequence

[0051] The UE should assume that the reference signal sequence r(m) is defined as:

[0052]

[0053] The pseudo-random sequence c(i) is defined in Section 5.2.1. The pseudo-random sequence generator should be initialized as follows:

[0054]

[0055] in, The timeslot number is the downlink PRS sequence ID. It is given by the higher-level parameter dl-PRS-SequenceID, where l is the OFDM symbol in the time slot to which the sequence is mapped.

[0056] The PRS sequence is obtained by modulating a Gold sequence using Quadrature Phase Shift Keying (QPSK). The initialization function for the Gold sequence is c. init Its design requires distinguishing the PRS of each TRP, maintaining the randomization of interference between the DL PRS of each TRP and good sequence cross-correlation characteristics.

[0057] (4) PRS mapping

[0058] For each configured downlink PRS resource, the UE should assume that the sequence r(m) is factored by β. PRS Scale and map to resource units (k, l) according to the following equation. p，μ :

[0059]

[0060] m = 0, 1, ...

[0061]

[0062]

[0063] When the following conditions are met:

[0064] Resource unit (k,l)p,μ Located within the resource block occupied by the downlink PRS resources configured for the UE;

[0065] Symbol l is not used by any synchronization signal / physical broadcast channel block (SS / PBCH) block of downlink PRS transmitted from the same serving cell by the serving cell or by any SS / PBCH block of a non-serving cell. Its time-frequency position is provided by a higher layer to the UE for transmission of downlink PRS from the same non-serving cell.

[0066] The timeslot number satisfies condition 7.4.1.7.4 in clause 7.4.

[0067] (5) Design of Multi-Port Channel State Information Reference Signal (CSI-RS)

[0068] CSI-RS with multiple ports can be divided into different Code Domain Multiplexing (CDM) groups, where the time-frequency positions of CSI-RS in different CDM groups can be different. A CDM group occupies contiguous resource element (RE) positions in the time and / or frequency domains, and different ports in a CDM group are distinguished by frequency domain orthogonal codes (FD-OCC) and / or time domain orthogonal codes (TD-OCC), occupying the same time and frequency domain positions. Please refer to Table 2.

[0069] Table 2

[0070]

[0071] (6) CSI-RS sequence design

[0072] The UE should assume that the reference signal sequence r(m) is defined as:

[0073]

[0074] The pseudo-random sequence c(i) is defined in Section 5.2.1. The pseudo-random sequence generator should be initialized as follows:

[0075]

[0076] At the beginning of each OFDM symbol, where It is the slot number within the radio frame, and the OFDM symbol number within the slot, which is equal to the higher-layer parameter scrapblingID or sequenceGenerationConfig.

[0077] (7) CSI-RS mapping

[0078] For each configured CSI-RS, the UE should assume that the sequence r(m) is mapped to resource element (k,l). p,μ ,according to:

[0079]

[0080]

[0081]

[0082]

[0083]

[0084] n = 0, 1, ...

[0085] When the following conditions are met:

[0086] Resource unit (k,l) p,μ Within the resource block occupied by the CSI-RS resources configured in the UE, the reference point with k=0 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 number of ports X is given by the higher-layer parameter nrofPorts.

[0087] The multi-port positioning reference signal configuration method, apparatus, and communication equipment provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0088] To address the issue of insufficient positioning accuracy when using a single-port positioning reference signal for positioning, please refer to... Figure 3 This application provides a multi-port positioning reference signal configuration method, including:

[0098] In this application embodiment, the receiving node may optionally include, but is not limited to: UE, TRP, RSU in the sidelink, base station in the sidelink, and / or UE in the sidelink.

[0099] For example: in UU interface-based positioning, the downlink positioning sending node is the TRP or base station, and the receiving node is the UE; in uplink positioning, the sending node is the UE, and the receiving node is the TRP or base station. In PC5 interface-based positioning, the sending node is the Sidelink UE, and the receiving node is another sidelink UE; or, the sending node is the RSU or UE, and the receiving node is the UE or RSU.

[0106] 2) Port index;

[0107] Optionally, the port index can be a local port index, such as 0, 1, ...; or a general port index, such as 5000, 5001, ... 5000 + N - 1, i.e., Port i = 5000 + i.

[0108] 3) Locate the reference signal port group;

[0109] 4) Port location identifier.

[0110] In this embodiment of the application, optionally, positioning reference signal ports with different location identifiers are not co-located, while positioning reference signal ports with the same location identifier are co-located.

[0111] The configuration of the positioning reference signal port group is described below.

[0116] In this embodiment of the application, optionally, each of the positioning reference signal port groups corresponds to its own positioning reference signal port group index.

[0117] In this embodiment of the application, optionally, the positioning reference signal port groups corresponding to different location identifiers are non-co-located.

[0118] In this embodiment of the application, optionally, different positioning reference signal port groups correspond to their respective number of positioning reference signal ports, and the number of positioning reference signal ports in different positioning reference signal port groups may be the same or different.

[0128] The location PMI is explained as follows: the receiving node measures the location reference signals of multiple ports, obtains the channel response of different ports, and performs a codebook traversal process to obtain the best codebook that matches the channel. The best codebook index is the location PMI.

[0129] In this embodiment of the application, optionally, different positioning reference signal port groups correspond to different positions and / or orientations within the positioning reference signal transmitting node.

[0130] In this embodiment, a positioning reference signal port group corresponds to an antenna reference point (ARP), or a positioning reference signal port group corresponds to a distributed antenna in a sidelink UE.

[0141] In this embodiment of the application, the coordinates may optionally be two-dimensional or three-dimensional coordinates.

[0142] In this embodiment of the application, optionally, the relative position information between the positioning reference signal port groups is obtained with reference to the position of a reference point, wherein the position of the reference point is the position of the reference port group or a specified position.

[0148] Optionally, if the CDM port group contains one positioning reference signal port, the CDM port group is equivalent to the positioning reference signal port.

[0149] In other words, if the positioning reference signal ports within a positioning reference signal port group are mapped to the same time-frequency location and can be distinguished by CDM, then the positioning reference signal port group can also be called a CDM port group.

[0150] In this embodiment of the application, optionally, the positioning reference signal port of the positioning reference signal transmitting node is determined by at least one of the following IDs:

[0151] 1) Locate the reference signal port ID;
