In order to facilitate understanding of the technical solution of the embodiments of the present application, the technical solution of the present application is described in detail below through specific embodiments. The following related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application. Embodiments of the present application include at least some of the following.

The positioning architecture introduced in Release 16, R16 and Release 17, R17 is mainly composed of a terminal (UE), a plurality of base stations (gNB), an access and mobility management function (ACCESS AND Mobility Management Function, AMF) entity and a location management function (Location Management Function, LMF) entity. In a first step, the UE and/or the gNB transmit Sounding REFERENCE SIGNAL, SRS and/or Positioning Reference Signals (PRS) according to a known configuration pattern. And then, the gNB and/or the UE measure the SRS and/or the PRS according to the known configuration style, and obtain measurement quantities related to positioning such as departure angle, arrival angle, distance difference and the like. And finally, summarizing the measurement quantities to a terminal or an LMF to perform positioning, and obtaining a final positioning result.

In a 5G positioning system, the orthogonality of the reference signals sent by different terminals/gnbs should be maintained, so that the signals measured by each party in the system can be ensured to fix the position of a point from one point, and the ensuring is fundamental to the positioning estimation. In addition, orthogonality may be ensured in at least one of the time/frequency/code domains.

Specifically, for example, the configuration of SRS and PRS and their measurements may be illustrated based on a positioning method of multiple round trip transmission times (multi Round Trip Time, multi-RTT), as shown in fig. 2. In step 3a in fig. 2, the gNB configures resources of the uplink SRS for the terminal (UE), and then activates the terminal (UE) to perform SRS transmission operation in step 5 a. In step 6, the LMF informs each gNB of the SRS resource configuration of the terminal (UE) nearby through an NR positioning protocol a (New Radio Positioning Protocol a, NRPPa) measurement request (measurement Request), and requires each gNB to measure the SRS sent by the terminal (UE), and finally in step 11, each gNB reports the measurement results collected by each gNB to the LMF entity. In addition, for the downlink measurement direction, in the 7 th and 8 th steps, the network firstly transmits unique downlink PRS configuration information of each gNB to the terminal (UE), then activates the terminal (UE) to perform downlink measurement, and finally in the 10 th step, the terminal (UE) transmits a message (ProvideLocationInformation msg) that the measurement result provides location information through a long term evolution positioning protocol (Evolution Positioning Protocol, LPP) to the LMF entity.

For better understanding of the embodiments of the present application, the downlink positioning reference signals (downlink positioning REFERENCE SIGNALS, DL PRS) related to the present application are described.

Configuration information of the NR DL PRS is provided to the UE by the LMF through LPP protocol signaling. The parameter configuration of DL PRS adopts a four-layer signaling structure, expressed from top layer to bottom layer as:

A positioning frequency layer (Positioning Frequency Layer, PFL);

Transmitting a reception point (Transmission Reception Point, TRP);

DL PRS resource set (PRS resource set);

DL PRS resources (PRS resources).

Within each positioning frequency layer (positioning frequency layer), the UE is configured with multiple TRPs to transmit DL PRS signals at the same frequency point. And one or two DL PRS resource sets can be configured in each TRP, which configures all DL PRS resources that this TRP transmits on a certain frequency point. And multiple DL PRS resources may be configured within each set of DL PRS resources, each DL PRS resource may represent a transmit beam of one TRP and different DL PRS resources may represent different transmit beams of the TRP.

According to the specifications of R16, a DL PRS configuration of 4 Positioning Frequency Layers (PFLs) may be provided at most for one terminal (UE). The configuration parameters of the following PRS signals are provided in the parameter structure of each Positioning Frequency Layer (PFL):

subcarrier spacing of PRS signals;

A Cyclic Prefix (CP) length of the PRS signal;

Frequency domain resource bandwidth of PRS: the value of the parameter is the number of physical resource blocks (Physical Resource Block, PRB) allocated to the PRS signal, the minimum value of the PRS resource bandwidth is 24 PRBs, the granularity is 4 PRBs, and the maximum value is 272 PRBs;

frequency domain starting frequency position of PRS resources: this parameter defines an index number of a starting PRB allocated in the frequency domain from the PRS signal, the index number of the PRB being defined with respect to a point a (PointA) of the PRS;

a frequency domain reference point PointA of the PRS signal;

comb (Comb) size combN of the PRS signal.

The PRS parameters configured within each Positioning Frequency Layer (PFL) are applied to all PRS resources contained within the Positioning Frequency Layer (PFL). That is, within one Positioning Frequency Layer (PFL), all PRS signals from multiple different TRPs may be transmitted on the same frequency subband using the same subcarrier spacing and CP length, the same comb size, and occupy exactly the same bandwidth. Such a design may support that the UE is able to receive and measure PRS signals from multiple different TRPs on the same frequency point at the same time.

The parameters of the TRP layer include an ID parameter for uniquely identifying the positioning TRP, the physical cell ID of the TRP, the NR cell global identity (NR Cell Global Identity, NCGI) of the TRP and the absolute radio channel number (Absolute Radio Frequency Channel Number, ARFCN) of the TRP. A maximum of 2 DL PRS resource sets may be configured within each TRP layer. The layer parameters of the DL PRS resource set configure the following parameters that apply to all DL PRS resources contained within the resource set:

DL PRS resource set identification ID (nr-DL-PRS-ResourceSetID);

Transmission period and slot offset of DL PRS (DL-PRS-Periodicity-and-ResourceSetSlotOffset): this parameter defines the time domain transmission behavior of all DL PRS resources contained within this set of DL PRS resources; the transmission period of the configurable DL PRS is a minimum of 4 milliseconds and a maximum of 10240 milliseconds; the configuration of DL PRS supports flexible subcarrier spacing including 15KHz,30KHz,60KHz and 120KHz; the range of DL PRS transmission period values that can be configured is the same with different subcarrier spacing;

Repetition factor of DL PRS resource (DL-PRS-ResourceRepetitionFactor): the parameter defines the repeated transmission times of one PRS resource in each PRS period, the repeated transmission of the same DL PRS resource can be used by the UE to aggregate the DL PRS signal energy of multiple transmissions so as to increase the coverage distance and the positioning precision of the DL PRS, and in the FR2 system, the repeated transmission of the DL PRS resource is used by the UE to do the receiving beam scanning operation; the UE may receive repeated transmissions of the same DL PRS resource with different receive beams to find the best TRP transmit beam to UE receive beam matching; in another aspect, repeated transmission of DL PRS resources increases PRS overhead, and in the R16 specification, the repetition factor of DL PRS resources takes on values of 1,2,4,6,8, 16 and 32.

Time interval for DL PRS resource repeat transmission (DL-PRS-ResourceTimeGap): this parameter defines the number of slots between two consecutive repeated transmissions of the same PRS resource;

Muting (multiplexing) configuration of DL PRS: this parameter is used to define that DL PRS signals are not transmitted on some allocated time-frequency resources (called multiplexing), muting means that DL PRS signals are not transmitted on all allocated time-frequency resources, but are not intended to be transmitted on some designated time-frequency resources, which on the one hand may avoid collisions with other signals, such as SSBs, and on the other hand may avoid interference between signals transmitted by different TRPs, for example, to switch off DL PRS transmission of a TRP at some time instants so that the UE can receive DL PRS signals from distant TRPs, the multiplexing operation of PRS will be explained in detail in the following description, which is not repeated here.

The number of OFDM symbols occupied by DL PRS resources (DL-PRS-NumSymbols): the number of orthogonal frequency division multiplexing (Orthogonal frequency-division multiplexing, OFDM) symbols allocated for one DL PRS resource within one slot is defined.

As previously described, all parameters configured within this layer configuration of one DL PRS resource set will apply to all DL PRS resources contained within this resource set. Thus, all DL PRS resources within the same DL PRS resource set may be transmitted with the same periodicity, the same number of repeated transmissions, and occupy the same number of OFDM symbols.

Each DL PRS resource may be configured with the following parameters:

a DL PRS resource identification ID (nr-DL-PRS-ResourceID);

Sequence ID of DL PRS (DL-PRS-SequenceID);

Initial frequency domain resource unit offset for DL PRS (DL-PRS-CombSizeN-AndReOffset): the parameter defines a frequency domain resource unit offset value used by the resource mapping of the DL PRS resource on the first allocated OFDM symbol in a time slot, and according to the parameter and the relative offset value, the UE can determine the frequency domain resource unit offset value used by the resource mapping on each OFDM symbol;

Resource slot offset for DL PRS (DL-PRS-ResourceSlotOffset): this parameter defines a slot offset relative to the set of DL PRS resources, which can determine the slot position where each DL PRS resource is located;

OFDM symbol offset for DL PRS (DL-PRS-ResourceSymbolOffset): this parameter defines the time-frequency resource allocation position of a DL PRS resource within a slot, which indicates the starting OFDM symbol index number within a slot;

QCL information of DL PRS (DL-PRS-QCL-Info): this parameter provides Quasi Co-sited information (QCL) of the DL PRS signal.

In order to better understand the embodiment of the present application, the configuration of the positioning SRS signal related to the present application is described.

Configuration information of the positioning SRS signals is provided to the user UE by the gNB of the serving cell through radio resource control (Radio Resource Control, RRC) signaling. The system configures the positioning SRS signals in the same manner as multiple-input multiple-output (Multiple Input Multiple Output, MIMO) SRS signals. One user UE may be configured with one or more sets of positioning SRS signal resources. And one set of positioning SRS signal resources may include one or more positioning SRS signal resources. The biggest difference between the positioning SRS signals and the MIMO SRS signals is that the positioning SRS signals need to be transmitted to the TRP of the non-serving cell, so that multiple TRPs can measure the uplink positioning measurement value of the same user and thus calculate the position of the user.

In terms of time domain transmission, the positioning SRS signal inherits all time domain transmission behaviors supported by the MIMO SRS signal. That is, the positioning SRS signal supports periodic transmission, semi-persistent transmission and aperiodic transmission. The semi-persistent transmission is performed by a medium access control layer control unit (MEDIA ACCESS Control Control Element, MAC CE) to activate or deactivate the transmission. And the aperiodic positioning SRS signal is triggered and transmitted by downlink control information (Downlink Control Information, DCI). These are the same as the existing SRS signal transmission mechanism for MIMO.

Specifically, the UE positioning measurement result reporting procedure may be as shown in fig. 3. The request location information (RequestLocationInformation) in a long term evolution positioning protocol (Evolution Positioning Protocol, LPP) message sent by the location server is used by the location server to request a positioning measurement or location estimate from the target device, reflecting the positioning method selected by the positioning system and the reporting mode.

Specifically, for example, the request location information (RequestLocationInformation) field always contains a request location information generic element (commonIEsRequestLocationInformation) field in which the relevant configuration for reporting the result is specified. If the network decides to apply a certain positioning method, the network will further include a field or element corresponding to the positioning method, such as NR 16 request location information multiple RTT (NR-Multi-RTT-RequestLocationInformation-r 16) field.

Specifically, periodic reporting is supported by including a periodic report (periodicalReporting) field. For example, it is supported to configure event triggered reporting by including a trigger report (triggeredReporting) field, where the event is each time the primary cell is changed and/or the event is the maximum duration for which the trigger report is reached, in which the terminal reports the requested location information to the network when the primary cell is changed for the maximum duration of the trigger reporting.

For a better understanding of embodiments of the present application, the positioning of the relevant side rows (Sidelink) of the present application is described.

In an out-of-coverage (OOC) scenario of the network for lateral positioning, an Anchor terminal (Anchor UE) and a Target terminal (Target UE) which function similarly to the gNB (TRP) are both in a state of no connection with the 5G system. In this case, their sidelink positioning reference signals (sidelink positioning REFERENCE SIGNALS, S-PRS) are not governed by the positioning management function (Location Management Function, LMF) and the base station (gNB). In out-of-coverage scene, the system performs measurement on the S-PRS sent by the positioning target terminal through the anchor terminal, or the target terminal performs measurement on the S-PRS sent by the anchor terminal, and the system completes positioning by combining the position information of the anchor terminal.

In an in-coverage (IC) scenario of sideline positioning, both the anchor terminal and the positioning target terminal are in a state that the 5G system is connected, where the configuration of the S-PRS is controlled by the LMF and/or the gNB, and possible options are as follows:

The S-PRS of the anchor terminal is controlled by LMF (similar to NR DL PRS), and the S-PRS of the target terminal is controlled by gNB (similar to NR SRS);

S-PRS of the anchor terminal and the target terminal are controlled by gNB;

the S-PRS of the anchor terminal and the target terminal are controlled by LMF.

In the network Partial coverage (Partial coverage) scenario, some anchor terminals and positioning target terminals are in an IC scenario, and some anchor terminals and positioning target terminals are in an OOC scenario. In this case, it is considered whether the configuration of the S-PRS still requires LMF and/or gNB management.

However, the current stage positioning only supports absolute positioning, i.e. the absolute position of the target terminal is acquired. Whereas for Sidelink positioning, relative positioning is an important part of the functionality. The target terminal may obtain relative location information with respect to the anchor terminal, such as distance, angle, etc. with respect to the anchor terminal.

In order to facilitate a better understanding of the embodiments of the present application, the problems addressed by the present application will be described.

Unlike absolute positioning, relative positioning reflects the relative positional relationship between the target UE and the anchor UE (e.g., the change in relative distance between the front and rear vehicles in a car networking scenario). The existing periodic position information is reported, if the periodic configuration is too sparse, the change condition of the relative position relation cannot be reflected in real time; if the periodic configuration is too dense, excessive signaling overhead may result. Therefore, methods such as reporting of position information triggered by the introduction of a change in the relative position relationship are required.

Based on the above problems, the application provides a terminal positioning scheme, which can reflect the relative position change condition between the first terminal and the second terminal in real time by determining whether to report the measurement result for determining the relative position information between the first terminal and the second terminal based on event-triggered measurement report condition information, thereby improving the sideways positioning effect.

The technical scheme of the application is described in detail below through specific embodiments.
