Patent Description:
In a long term evolution (Long Term Evolution, LTE) system, a positioning reference signal (Positioning Reference Signal, PRS) is a reference signal (Reference Signal, RS) used for downlink positioning. A terminal (User Equipment, UE) measures PRSs sent from a plurality of cells (cell) or a plurality of transmission points (Transmission Point, TP), and obtains a reference signal time difference (Reference Signal Time Difference, RSTD) between the plurality of cells or transmission points. Then the UE sends RSTD information obtained through measurement to a location server, and the location server obtains a location of the UE through calculation.

In a downlink positioning method, the UE does not obtain precise time of arrival (Time of Arrival, TOA), and an estimated location is determined by time differences of arrival (Time Difference of Arrival, TDOA) (represented by time difference of reference signal (Time Difference of Reference Signal, RSTD) in a standard) of at least three base stations, that is, determined by relative time rather than absolute time. In principle, two base stations participating in positioning can determine one hyperbolic trajectory of the UE, and three base stations participating in positioning can define the UE within a very small area. One more base station added may define the UE within another area, and a location range of the UE may be narrowed by using an overlapping part. In downlink positioning in LTE, the UE needs to measure PRSs from a plurality of base stations or a plurality of cells to obtain RSTDs, and then report RSTD information to a location server on a network side. Finally, the location server calculates the location of the UE.

Considering that in a new radio (New Radio, NR) system, a PRS is sent in a serving cell or a neighboring cell by beam sweeping (beam sweeping), the UE may need to measure PRSs of multiple beams (beam) from the serving cell or the neighboring cell during positioning. Reporting of multi-beam measurement results causes a great increase of complexity and overheads. In a case of multiple beams, how to properly report multi-beam measurement results has not been clearly defined, and needs to be resolved urgently.

<CIT> provides a method for measuring and reporting a positioning reference signal, which includes: measuring positioning reference signals (PRSs) to which beamforming is applied; and reporting, to a base station, measurement results for at least two of the PRSs, where the PRSs are received via different transmission beams, and the terminal reports to the base station at least one from among transmission beam identification information indicating through which transmission beam each of the at least two PRSs has been received and resource identification information indicating through which resource each of the at least two PRSs has been received, together with the measurement results.

<CIT> provides a method for receiving device position determination, which includes: receiving beamformed position reference signals (BF-PRSs) on communications beams from at least two transmitting devices in accordance with a BF-PRS configuration, making at least one observed time difference of arrival (OTDOA) measurement in accordance with the BF-PRSs on the plurality of communications beams, and transmitting OTDOA feedback including the at least one OTDOA measurement.

"NR beam management supporting multi-gNB measurements for positioning" (3GPP TSG RAN WG1 Meeting #<NUM>; R1-<NUM>; Fraunhofer IIS, Fraunhofer HHI) proposes how to enable the necessary measurements on reference signals used for positioning that are transmitted or received within highly directional beams from or at different locations.

Embodiments of this disclosure, as defined in the appended claims, provide methods for reporting positioning measurement information, a terminal, and a network device to resolve a problem of reporting multi-beam measurement results.

The scope of the present invention is determined only by the scope of the appended claims. More precisely, in a first aspect, the present invention provides a method for reporting positioning measurement information according to claim <NUM> and further detailed in the dependent claims referring back to this claim. A corresponding terminal is provided in claim <NUM>.

In a second aspect, the present invention provides a method for reporting positioning measurement information according to claim <NUM> and further detailed in the dependent claims referring back to this claim. A corresponding communication system is provided in claim <NUM>.

In the embodiments of this disclosure, during reporting of positioning measurement information, RSRP or TOA may be used to determine measurement results of N beams for reporting, so that reporting of positioning measurement information is implemented when PRSs of multiple beams are received. Because the beam measurement results to be reported may be properly selected based on the RSRP and the TOA, overheads for reporting the positioning measurement information can be reduced.

The following describes the embodiments of this disclosure with reference to the accompanying drawings. A method for reporting positioning measurement information, a terminal, and a network device provided in the embodiments of this disclosure may be applied to a wireless communications system. The wireless communications system may be a <NUM> system, or an evolved long term evolution (Evolved Long Term Evolution, eLTE) system, or a later evolved communications system.

<FIG> is a structural diagram of a network system to which an embodiment of this disclosure may be applied. As shown in <FIG>, the network system includes a terminal <NUM> and a network device <NUM>. The terminal <NUM> may be a user terminal or another terminal-side device, for example, a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (personal digital assistant, PDA), a mobile Internet device (Mobile Internet Device, MID), or a wearable device (Wearable Device). It should be noted that a specific type of the terminal <NUM> is not limited in this embodiment of this disclosure. The network device <NUM> may be a <NUM> base station, or a base station of a later version, or a base station in another communications system, or is referred to as a NodeB, or an evolved NodeB, or a transmission and reception point (Transmission Reception Point, TRP), or an access point (Access Point, AP), or other terms in the art. As long as a same technical effect is achieved, the network device is not limited to a specific technical term. In addition, the network device <NUM> may be a master node (Master Node, MN) or a secondary node (Secondary Node, SN). It should be noted that the <NUM> base station is used merely as an example in this embodiment of this disclosure, rather than limiting a specific type of the network device.

<FIG> is a flowchart of a method for reporting positioning measurement information according to an embodiment of this disclosure. The method is applied to a terminal.

Step <NUM>: Receive first configuration information from a network device.

In this embodiment of this disclosure, the first configuration information is used to configure the terminal to report measurement results of beams in each cell participating in positioning. Specifically, the network device may transmit PRSs on different beams in each cell by beam sweeping, and the terminal measures the PRSs transmitted on all the beams to obtain beam measurement results. Specifically, a manner of sending the first configuration information may be set based on an actual requirement, and is not further limited herein. For example, in an optional embodiment, the first configuration information may be sent by using higher layer signaling.

Step <NUM>: Report a measurement result of a beam group based on the first configuration information.

The beam group is used to transmit a positioning reference signal PRS, and the beam group includes N beams determined by reference signal received power (Reference Signal Received Power, RSRP) or time of arrival TOA, where N is a positive integer, the N beams are beams in a first cell, and the first cell is one of cells participating in positioning.

It should be noted that in an optional embodiment, the beam group of the first cell may be determined based on TOA; and in another optional embodiment, the beam group of the first cell may be determined based on RSRP and TOA. The N beams includes any one of the following:.

It should be understood that when the manner of determining the N beams is top L beams in ascending order of time of arrival TOA and top K beams in descending order of RSRP in the first cell, the N beams are the top L beams and the top K beams. The top K beams in descending order of RSRP may be top K beams in descending order of RSRP in the first cell, or may be all beams whose RSRP is higher than the preset threshold in the first cell, or may be top K beams selected from M beams whose RSRP is higher than the preset threshold in descending order of RSRP. The top L beams in ascending order of TOA may be top L beams in ascending order of TOA in the first cell, or may be top L beams selected from M beams whose RSRP is higher than the preset threshold in the first cell in ascending order of RSRP.

The top L beams selected based on the RSRP and the top K beams selected based on the TOA may include a same beam. In this case, a measurement result of only one beam is actually reported during measurement result reporting. Therefore, N < L + K. In other words, in a case in which the N beams are the top L beams and the top K beams, when the top L beams and the top K beams do not include a same beam, N = L + K; or when the top L beams and the top K beams include a same beam, N is the actual number of beams. In this way, repeated reporting of beam measurement results can be avoided, and overheads of beam measurement result reporting can be reduced.

For example, the top L beams in ascending order of TOA include beam A, beam B, and beam C, and the top K beams in descending order of RSRP include beam B, beam D, beam E, and beam F. In this case, the number of beams actually reported is <NUM>, that is, N = <NUM>.

Specifically, when the measurement result of the beam group is reported, report content may be set based on an actual requirement. For example, in this embodiment, the report content may include at least one of a beam identifier (beam ID), a cell identity (cell ID), a positioning reference signal identifier (PRS ID), a reference time difference (Reference time difference), an additional path (Additional path), reference quality (reference quality), a reference signal time difference, reference signal time difference quality (RSTD quality), RSRP, reference signal received power quality (RSRP quality), and a port (port).

In this embodiment of this disclosure, during reporting of positioning measurement information, RSRP or TOA may be used to determine measurement results of N beams for reporting, so that reporting of positioning measurement information is implemented when PRSs of multiple beams are received. Because the beam measurement results to be reported may be properly selected based on the RSRP and the TOA, overheads for reporting the positioning measurement information can be reduced.

Further, the measurement result of the beam group includes a first measurement result and/or a second measurement result, where the first measurement result is a measurement result associated with a downlink time difference of arrival (Down Link Time Difference Of Arrival, DL-TDOA), and the second measurement result is a measurement result associated with a downlink angle of departure (Down Link Angle Of Departure, DL-AoD).

It should be noted that for measurement results of beams, the terminal may report all or a part of the measurement results. For example, in an optional embodiment, the first configuration information may alternatively be used to indicate the terminal to report the first measurement result or the second measurement result.

Specifically, the network device can configure the DL-TDOA technology and the DL-AoD technology separately. For example, when the network device configures the DL-TDOA technology, the terminal only reports a measurement result associated with the DL-TDOA technology. For example, the measurement result may include at least one of an RSTD, RSTD quality, an additional path, reference quality, RSRP, and RSRP quality. When the network device configures the DL-AoD technology, the terminal only reports a measurement result associated with the DL-AoD technology. For example, the measurement result may include at least one of RSRP and RSRP quality.

In another optional embodiment, the network device may not configure the DL-TDOA technology and the DL-AoD technology separately. In this case, in an implementation solution, the terminal may report all measurement results of beams regardless of the technology. In another implementation solution, the measurement result associated with the DL-TDOA technology or the measurement result associated with the DL-AoD technology may be reported based on report content configured by the network device. Configuration information corresponding to the report content may be carried in a positioning assistance data signaling field of a higher layer protocol (such as LPP), or carried in positioning information request signaling.

Generally, the cells participating in positioning usually include at least three cells. Specifically, the cells participating in positioning include a reference cell and a neighboring cell; or the cells participating in positioning include a neighboring cell. The cells participating in positioning may be configured by the network device. The cell herein may not be limited to a physical cell, but may also be a virtual cell, such as a TP or a TRP. The reference cell may be an RSTD reference cell (the cell is used as a reference for calculating an RSTD), or may be an RSRP reference cell (the cell is used as a reference for calculating relative RSRP values of other cells and other beams). The neighboring cell is a cell participating in positioning other than the reference cell. In this embodiment, the RSTD reference cell and the RSRP reference cell may be a same cell or different cells.

It should be noted that during RSTD and RSRP calculation, it is usually necessary to perform calculation based on the reference beam reference beam. For different values of N, the following describes in detail a definition of a corresponding reference beam.

In an optional embodiment, when N is equal to <NUM>, a beam in a beam group of the reference cell is a reference beam.

In another optional embodiment, when N is greater than <NUM>, the method further includes:
receiving second configuration information from the network device, where the second configuration information is used to configure a reference beam, and the reference beam is a beam in a beam group of the reference cell.

The reference beam is used as a reference for calculating timing (timing) of a first beam; or the reference beam is used as a reference for calculating RSRP of a first beam; or the reference beam is used as a reference for calculating timing and RSRP of a first beam. The first beam is a beam in the beam group of the reference cell or a beam in a beam group of the neighboring cell, and the first beam is different from the reference beam.

In this embodiment, when N is equal to <NUM>, the terminal reports measurement information based on only a beam of the reference cell, where the beam may be considered as a reference beam (reference beam). When N is greater than <NUM>, the network device defines a reference beam for the terminal. In this way, it is convenient for the terminal to report timing and/or RSRP information of other beams in the reference cell or neighboring cell based on the timing and/or RSRP value of the reference beam. Specifically, the terminal may determine a beam as the reference beam based on an instruction of the network device; or the terminal may directly obtain information of the reference beam based on a network-side configuration.

For example, when N is greater than <NUM>, the reference beam is any one of the following beams:.

In other words, the reference beam may be a beam among multiple beams in the reference cell. The beam may be the beam with the largest RSRP, the beam with the smallest TOA, or one of other designated beams.

Further, a manner of reporting the measurement result of the beam group may be set based on an actual requirement. For example, in this embodiment, when N is greater than <NUM>, the reporting a measurement result of a beam group may include either of the following manners:.

In the foregoing manner <NUM>, the reporting a measurement result of each beam in the beam group may include:.

In the foregoing manner <NUM>, a manner of joint processing includes any one of the following:.

For example, in a specific implementation solution, firstly, the terminal obtains TOA information of multiple beams in the reference cell through measurement. Based on an instruction of the network side, the terminal directly performs one of the following processing on TOA information of N beams:.

Secondly, the terminal obtains TOA information of N beams of the neighboring cell through measurement. Based on an instruction of the network device, the terminal directly performs one of the following processing on TOA information of multiple beams of the neighboring cell:.

Finally, the terminal reports RSTD information, and information such as a cell ID, a beam ID, a PRS ID, and a port that are associated.

After joint processing is performed on the measurement result of the beam group in this embodiment of this disclosure, a joint processing result is reported. In this way, a size and complexity of information reported by the terminal can be reduced, and processing complexity of the network device can also be reduced.

For better understanding this disclosure, the following describes in detail a terminal reporting process corresponding to different values of N.
