Description

Method and device for reporting measurement of aperiodic positioning reference signal

Technical Field

The present application relates to the field of wireless communications technologies, and in particular, to a method and an apparatus for reporting measurement of an aperiodic positioning reference signal.

Background

In the 3GPP standard, various positioning techniques such as a downlink-time of arrival (DL-TDOA), a downlink-angle of departure, DL-AOD, an uplink-time of arrival (UL-TDOA), an uplink-angle of arrival (UL-AOA), and a multi-user round trip time (multi-RTT) are supported. The DL-TDOA, UL-TDOA and multi-RTT algorithm are positioning technologies based on arrival time, that is, a receiving end is required to measure the arrival time of a signal sent by a sending end, and then the arrival time is converted into distance information between the two signals, so as to obtain the position of a target to be positioned. DL-AOD and UL-AOA are angle-based positioning techniques, i.e., a receiving end measures the angle of arrival of a reference signal transmitted by a transmitting end, and then infers the location of the receiving end from angle information of the receiving end with a plurality of transmitting ends of known locations.

The premise of realizing the positioning function is that the receiving and transmitting parties need to coordinate to measure positioning reference signals (positioning reference signal, PRS), and follow-up positioning calculation is carried out according to the measurement result of the PRS. In the NR Rel-16 protocol version, only periodic PRS transmissions are supported, i.e. once the positioning function is turned on, the network device continuously transmits PRS according to a configured period, which causes the following two problems:

In the first aspect, data cannot be transmitted and received on symbols of the PRS, resulting in a decrease in data throughput rate, and for a User Equipment (UE), the UE needs to receive PRS from multiple network devices, which is too resource-intensive and may even interrupt data reception. On the other hand, the UE needs to receive PRS in a specific period, if the period is too large, the delay of the entire positioning increases, and if the period is too small, the resource overhead of the positioning increases.

Disclosure of Invention

The embodiment of the application provides a measurement reporting method and device of aperiodic PRS (packet data channel), which are used for reducing positioning time delay and positioning resource overhead.

In a first aspect, a measurement reporting method of aperiodic PRS is provided. The method may be performed by the terminal device or a chip that resembles the functionality of the terminal device. In the method, the terminal device may receive aperiodic PRS configuration information. The terminal device may also receive a first value from the network device. The first value may be used to indicate reporting configuration information of n aperiodic PRSs of the terminal device. The reporting configuration information of one aperiodic PRS may include m aperiodic PRS reporting time information. n and m are integers greater than 0. The terminal device may receive the aperiodic PRS based on the aperiodic PRS configuration information. The terminal device may report a measurement report of the aperiodic PRS based on one of the received aperiodic PRS and n×m aperiodic PRS reporting time information.

Based on the above scheme, the network device may trigger the terminal device to perform measurement and reporting of the aperiodic PRS, and the network device may indicate n×m aperiodic PRS reporting time information to the terminal device. Therefore, the terminal device may determine the reporting time of the aperiodic PRS at one of the n×m reporting time information of the aperiodic PRS, and report the measurement report of the aperiodic PRS at the reporting time of the aperiodic PRS. Since the PRS is an aperiodic PRS, positioning resource overhead can be reduced, and positioning of a terminal device can be achieved by the aperiodic PRS when there is a positioning requirement.

In one possible implementation, the terminal device may receive the second value from the network device. The terminal device may determine, based on the second value, one aperiodic PRS reporting time information from the n×m aperiodic PRS reporting time information; one aperiodic PRS reporting time information may be used to determine a transmission time of a measurement report reporting the aperiodic PRS.

Based on the above scheme, the terminal device may determine, through the second value from the network device, one aperiodic PRS report time information, and then determine a transmission time of a measurement report of the aperiodic PRS, so that the transmission time of the measurement report of the aperiodic PRS accords with scheduling of the network device.

In one possible implementation, the second value may be used to indicate transmission time information of communication data of the terminal device. Alternatively, the communication data may not include measurement reports of aperiodic PRS and aperiodic CSI.

Based on the scheme, the terminal equipment can determine the reporting time information of the aperiodic PRS according to the transmission time information of the communication data, and the possibility of collision between the measurement report of the aperiodic PRS and the communication data can be reduced.

In one possible implementation, when n is equal to 1, the terminal device may select one aperiodic PRS reporting time information indicated by the second value from the m aperiodic PRS reporting time information. Or when n is greater than 1, the terminal device may select the aperiodic PRS reporting time information indicated by the second value from the reporting configuration information of each aperiodic PRS, and the terminal device may select one aperiodic PRS reporting time information from the n aperiodic PRS reporting time information.

Based on the scheme, the terminal equipment can determine the reporting time information of the aperiodic PRS based on the second value indicated by the network equipment, so that the possibility of collision between the measurement report of the aperiodic PRS and the communication data can be reduced.

In one possible implementation manner, the terminal device may select the aperiodic PRS reporting time information with the largest value from the n aperiodic PRS reporting time information.

Based on the above scheme, when the network device indicates the reporting configuration information of the plurality of aperiodic PRSs to the terminal device, the terminal device may select n aperiodic PRS reporting time information according to the second value, and select the aperiodic PRS reporting time information with the largest value from the n aperiodic PRS reporting time information, and then determine the sending time of the measurement report of the aperiodic PRS, so that the terminal device has a longer time to receive and measure the PRS, and may improve positioning accuracy.

In one possible implementation, when the terminal device has communication data transmitted in the transmission time information indicated by the second value, the terminal device may determine a value with a large value in the determined one aperiodic PRS reporting time information and the second value. The terminal device can report the measurement report of the aperiodic PRS based on the value with large value.

Based on the above scheme, if the terminal device has communication data to be transmitted, the terminal device can report time information on the second value and the determined one aperiodic PRS, and report a measurement report of the aperiodic PRS, so that the terminal device can have a longer time to receive and measure the PRS.

In one possible implementation, when the terminal device does not have communication data to be transmitted at the transmission time indicated by the second value, the terminal device may report the measurement report of the aperiodic PRS based on the reporting time information of the aperiodic PRS.

Based on the above scheme, if the terminal device does not have communication data to be transmitted, the terminal device can report time information based on the determined one aperiodic PRS, report measurement report of the aperiodic PRS, and reduce positioning delay.

In one possible implementation, the terminal device may receive a third value indicating aperiodic CSI reporting time information for the terminal device to report aperiodic channel state information (channel state information, CSI). When the terminal device has communication data transmitted at the transmission time information indicated by the second value, the terminal device may determine a value having a large value among the fourth value and the second value. Wherein the fourth value is determined based on the third value and the determined one aperiodic PRS reporting time information. The terminal device can report the measurement report of the aperiodic PRS based on the value with large value.

Based on the scheme, when the terminal equipment is triggered to report the aperiodic CSI and report the aperiodic PRS and the communication data to be transmitted is to be transmitted, the terminal equipment can determine a value with a larger value based on the aperiodic CSI reporting time information, the transmission time information of the communication data and the aperiodic PRS reporting time information, so that the terminal equipment can report a measurement report of the aperiodic PRS based on the value with the larger value. Accordingly, the terminal device may be made more time to receive and measure PRS and aperiodic channel state information reference signals (channel state information reference signal, CSI-RS).

In one possible implementation, the fourth value is specifically a sum of the third value and a time indicated by the determined one aperiodic PRS reporting time information.

Based on the scheme, when the terminal equipment is triggered to report the aperiodic CSI and report the aperiodic PRS and the communication data to be transmitted is transmitted, the terminal equipment can sum the reporting time of the aperiodic CSI and the reporting time of the aperiodic PRS, then compare the sum with the second value, select a larger value, report the aperiodic PRS, and enable the terminal equipment to have more time to receive and measure the CSI-RS and PRS.

In one possible implementation, the terminal device receives a third value, which may be used to instruct the terminal device to report aperiodic CSI reporting time information of the aperiodic channel state information CSI report. The terminal device may report the measurement report of the aperiodic PRS based on the time information and the third value reported by the aperiodic PRS. Optionally, the terminal device may report a measurement report of the aperiodic PRS based on the fifth value; the fifth value may specifically be a sum of one aperiodic PRS reporting time information and the third value.

Based on the scheme, when the terminal equipment is triggered to report the aperiodic CSI and report the aperiodic PRS at the same time but has no communication data to be transmitted, the terminal equipment can report the aperiodic PRS based on the reporting time of the aperiodic CSI and the reporting time of the aperiodic PRS, so that the terminal equipment has more time to measure and report the CSI-RS and the PRS.

In one possible implementation, the terminal device may send the first capability information to the positioning server and/or the network device. The first capability information may include a positioning of the terminal device supporting aperiodic PRS.

Based on the scheme, the terminal equipment can send the capability information supporting the positioning of the aperiodic PRS to the positioning server and the network equipment, so that the network equipment and the positioning server trigger the terminal equipment to execute the reporting of the aperiodic PRS when the positioning service needs to be executed, and the overhead of positioning resources can be reduced.

In one possible implementation, the terminal device may send second capability information to the positioning server and/or the network device, where the second capability information may include that the terminal device supports aperiodic PRS reporting and aperiodic CSI reporting to trigger simultaneously. Alternatively, the second capability information may include that the terminal device does not support the aperiodic PRS reporting and the aperiodic CSI reporting are triggered simultaneously.

Based on the above scheme, the terminal device can report whether the aperiodic CSI report and the aperiodic PRS report are triggered simultaneously, and if the terminal device does not support the aperiodic CSI report and the aperiodic PRS report are triggered simultaneously, the network device or the positioning server does not send the first value and the third value to the terminal device at the same time, so that the terminal device can execute the aperiodic PRS report or execute the aperiodic CSI report.

In one possible implementation, the first value and the second value may be carried in downlink control information (downlink control information, DCI). Based on the above scheme, the network device may trigger the terminal device to execute reporting of the aperiodic PRS through DCI.

In a second aspect, an aperiodic PRS measurement reporting method is provided. The method may be performed by a network device or a chip that resembles the functionality of a network device. In the method, the network device may send a first value to the terminal device, where the first value may be used to indicate reporting configuration information of n aperiodic PRSs of the terminal device. The reporting configuration information of one aperiodic PRS may include m aperiodic PRS reporting time information, where n and m are integers greater than 0. The network device may receive a measurement report of the aperiodic PRS from the terminal device based on one of n x m aperiodic PRS reporting time information.

In one possible implementation, the network device may send a second value to the terminal device, which may be used to determine one of n×m aperiodic PRS reporting time information. The method for determining the aperiodic PRS reporting time information from the n×m aperiodic PRS reporting time information may be referred to in the description related to the first aspect, and will not be described herein.

Based on the above scheme, the network device may indicate a second value to the terminal device for determining the aperiodic PRS reporting time information such that the transmission time of the measurement report of the aperiodic PRS conforms to the scheduling of the network device.

In one possible implementation, the second value is used to indicate transmission time information of communication data of the terminal device.

When n is greater than 1, the network device may receive a measurement report of the aperiodic PRS based on one of the reporting time information of the n aperiodic PRS.

Based on the above scheme, the network device can determine the reporting time information of one aperiodic PRS to receive the measurement report of the aperiodic PRS based on the second value, so that the possibility of collision between the measurement report of the aperiodic PRS and communication data can be reduced.

In one possible implementation, the network device receives a measurement report of the aperiodic PRS based on one aperiodic PRS reporting time information with a maximum value of the reporting time information of the n aperiodic PRSs.

In one possible implementation, the network device may receive a measurement report of the aperiodic PRS based on the second value and a value of the determined one aperiodic PRS reporting time information that is large. Alternatively, the network device may receive measurement reports of aperiodic PRSs from the terminal device based on the determined one aperiodic PRS reporting time information.

Based on the above scheme, the network device may attempt to receive measurement reports of aperiodic PRS at the above two times. The network device receives the measurement report of the aperiodic PRS with a large value in the second value and the determined reporting time information of the aperiodic PRS, so that the possibility of collision between the measurement report of the aperiodic PRS and communication data transmitted by the terminal device can be reduced. The network equipment reports time information on the determined aperiodic PRS, and receives the measurement report of the aperiodic PRS, so that the time delay of positioning can be reduced.

In one possible implementation, the network device may send a third value to the terminal device, where the third value may be used to instruct the terminal device to report aperiodic CSI reporting time information of the aperiodic CSI report. The network device may receive a measurement report of the aperiodic PRS based on a value of the fourth value and the second value, where the fourth value is determined based on the third value and the determined one aperiodic PRS reporting time information. Alternatively, the network device may receive a measurement report of the aperiodic PRS from the terminal device based on the determined one aperiodic PRS reporting time information and the third value.

Based on the scheme, when the network equipment triggers the terminal equipment to execute the aperiodic CSI reporting at the same time, the network equipment can determine the reporting time of the aperiodic PRS based on the reporting time of the aperiodic CSI and the reporting time of the aperiodic PRS, so that the terminal equipment has more time to receive and measure PRS and CSI-RS.

In one possible implementation, the network device may receive second capability information from the terminal device; . The second capability information includes that the terminal equipment supports the simultaneous triggering of aperiodic PRS reporting and aperiodic CSI reporting. Or the second capability information includes that the terminal equipment does not support the simultaneous touch of aperiodic PRS reporting and aperiodic CSI reporting.

Based on the above scheme, the terminal device can report whether the aperiodic CSI report and the aperiodic PRS report are triggered simultaneously, and if the terminal device does not support the aperiodic CSI report and the aperiodic PRS report are triggered simultaneously, the network device does not send the first value and the third value to the terminal device at the same time, so that the terminal device can execute the aperiodic PRS report or execute the aperiodic CSI report.

In one possible implementation, the network device may send aperiodic PRS configuration information to the terminal device; the network device may transmit the aperiodic PRS based on the aperiodic PRS configuration information.

TDOA location techniques estimate the position of a target by calculating the intersection of hyperbolas. As shown in fig. 2, assuming that the locations of 3 base stations are known, the coordinates of the i-th base station are defined herein as (x _i ,y _i ) The coordinates of the object to be positioned are (x _UE ,y _UE ). Assuming that the 1 st base station is used as a reference base station, the UE respectively measures the arrival time difference Deltat between PRSs of other base stations and the reference base station _i1 . According to the definition of a hyperbola, where the distance between two fixed points on the hyperbola is the arrival time difference of PRS and the UE is located on the hyperbola with two base stations as focus, the following set of equations can be listed:

in the two equations above, c is the speed of light, since there are only two unknowns (x _UE ,y _UE ) By combining equations (1) and (2), we can obtain (x) _UE ,y _UE ) I.e. the location coordinates of the UE.

The positioning process and the positioning method can find that the premise of realizing the positioning function is that the receiving and transmitting sides need to coordinate to measure PRS, and the subsequent positioning calculation is performed based on the obtained related measurement result. In the NR Rel-16 protocol version, only periodic PRS transmission is supported, i.e. once the positioning function is started, the base station continuously transmits PRS according to a configured period, which causes the following two problems: in the first aspect, the UE cannot send and receive data on the symbol of the PRS, resulting in a decrease in data throughput rate, and for the UE, the UE needs to receive PRS from multiple network devices, which is too high in resource overhead and may even interrupt data reception. On the other hand, the UE needs to receive PRS with a specific period, if the period is too large, the delay of the entire positioning increases, and if the period is too small, the resource overhead of the positioning increases, as shown in fig. 3A.

Based on the above problems, the embodiment of the application provides a measurement reporting method of an aperiodic PRS. In the method, network equipment transmits an aperiodic PRS at a certain time, and terminal equipment measures the aperiodic PRS at a corresponding receiving time and reports a measurement result. The location management function network element (location management function, LMF) may process to obtain location information of the terminal device based on the measurement result reported by the terminal device.

Hereinafter, a data transmission time and an aperiodic channel state information reference signal (channel state information reference signal, CSI-RS) reporting time according to an embodiment of the present application will be described. First, the base station transmits downlink control information (down link control information, DCI) to the UE, wherein the DCI includes an indication field, CSI request (CSI request). The field indicates an aperiodic CSI trigger state, and each aperiodic CSI trigger state is associated with reporting configurations of one or more aperiodic CSI. The reporting configuration of the aperiodic CSI includes a CSI reporting time parameter list, and the numerical value in the parameter list represents a time slot offset for reporting the CSI. And the UE is specifically applicable to reporting configuration of which aperiodic CSI and time slot offset of which reporting CSI, and is indicated by DCI. In addition, a resource configuration of some CSI-RS is associated in one aperiodic CSI reporting configuration, that is, the UE needs to measure which CSI-RS resources and then report the CSI-RS resources, or the measurement result reported by the UE is obtained according to which CSI-RS measurements.

In addition, the DCI carries a field, which is used to indicate the time domain position where the physical uplink shared channel (physical uplink shared channel, PUSCH) is located and the number of occupied time domain symbols (Time domain resource assignment). Here, assuming that the time slot where the PUSCH is located is Ks, the time slot interval between the PUSCH scheduled by the DCI and the DCI is k2, and the time slot offset of the aperiodic CSI report is Y, the timing relationships among the DCI, the PUSCH, and the time slot where the aperiodic CSI report is located are shown in fig. 3B.

Specifically, if the time domain resource allocation field and the CSI request field are simultaneously present in one DCI, the actual time slot in which the PUSCH is located is determined by both fields. In version TS38.214-g30 of the standard protocol, there are the following provisions:

when the UE receives a DCI, the PUSCH indicated by the DCI is only used for data transmission without scheduling aperiodic CSI reporting, or the PUSCH is both scheduled for data transmission and indicated for aperiodic CSI reporting, and the time slot in which the PUSCH is actually located is indicated by the time-domain allocation field in the DCI, that is, the field indicates a time-slot offset value K ₂ The time slot of the PUSCH is: k (K) _s ＝n+K ₂ ；

When the UE receives a DCI, the PUSCH indicated by the DCI is only used to carry aperiodic CSI reporting information, and there is no data transmission, and at this time, the timeslot in which the PUSCH is located is determined not by the time-domain allocation field but by the CSI reporting time indicated by the CSI request field: k (K) ₂ ＝max _j Y _j (m+1)。

Wherein m is indicated by a time domain allocation field, Y _j Refers to the time slot offset, max, of the j-th aperiodic CSI report in one aperiodic CSI report configuration of DCI scheduling _j Refers to taking Y _j Is a maximum value of (a). The maximum value is taken because one DCI may trigger reporting of multiple aperiodic CSI, where the maximum slot offset in all aperiodic reports is taken as the aperiodic CSI reporting slot offset and the slot offset where PUSCH is located. The advantage of this is that it can ensure that the UE can get access to the PUSCH after measuring all the aperiodic CSI-RSs.

Note that aperiodic PRS is very different from aperiodic CSI-RS. First, aperiodic PRSs are issued by multiple network devices to UEs, which need to receive PRSs from the multiple network devices, and for each received PRS, the UE needs to perform correlation detection to determine its arrival time and received power, which can occupy a lot of chip resources. First, for positioning, at least PRSs of 3 network devices need to be measured to satisfy a basic positioning function, and a time interval for PRSs sent by different network devices to reach a UE is also uncertain. Also for most UEs, a measurement interval needs to be requested from the network device for PRS measurements, i.e. the UE only receives PRS during this measurement time window and does not receive other data or signals.

In summary, the UE needs to ensure enough time to receive and measure a valid PRS before reporting the aperiodic PRS measurements without affecting positioning accuracy.

The technical scheme of the embodiment of the application can be applied to various communication systems, such as: long term evolution (long term evolution, LTE) systems, worldwide interoperability for microwave access (worldwide interoperability for microwave access, wiMAX) communication systems, future fifth generation (5th Generation,5G) systems such as new generation radio access technologies (new radio access technology, NR), and future communication systems such as 6G systems.

The present application will present various aspects, embodiments, or features about a system that may include a plurality of devices, components, modules, etc. It is to be understood and appreciated that the various systems may include additional devices, components, modules, etc. and/or may not include all of the devices, components, modules etc. discussed in connection with the figures. Furthermore, combinations of these schemes may also be used.

The network architecture and the service scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided by the embodiments of the present application, and those skilled in the art can know that, with the evolution of the network architecture and the appearance of the new service scenario, the technical solution provided by the embodiments of the present application is applicable to similar technical problems.

To facilitate understanding of the embodiments of the present application, a communication system suitable for use in the embodiments of the present application will be described in detail with reference to the communication system shown in fig. 4. Fig. 4 shows a schematic diagram of a communication system suitable for use in the communication method of an embodiment of the application. As shown in fig. 4, the communication system 400 comprises a terminal device 401 and a network device 402, an access and mobility management function network element AMF403 and a location management function network element LMF404.

The functions of each network element or device of the communication system according to the embodiment of the present application are described in detail below:

the terminal device, which may also be referred to as a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device that provides voice and/or data connectivity to a user. For example, the terminal device may include a handheld device having a wireless connection function, an in-vehicle device, and the like. Currently, the terminal device may be: a mobile phone, a tablet, a notebook, a palm, a mobile internet device (mobile internet device, MID), a wearable device, a Virtual Reality (VR) device, an augmented reality (augmented reality, AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned (self-driving), a wireless terminal in teleoperation (remote medical surgery), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation security (transportation safety), a wireless terminal in smart city (smart city), or a wireless terminal in smart home (smart home), and the like. The terminal device shown in fig. 4 is shown as a UE, and is merely exemplary and not limited thereto.

A network device, which may also be referred to as AN access network device (AN), provides radio access services to the terminal device. The access network device is a device for accessing the terminal device to a wireless network in the communication system. The access network device is a node in a radio access network, which may also be referred to as a base station, and may also be referred to as a radio access network (radio access network, RAN) node (or device). Currently, some access network devices are exemplified by: gNB, transmission reception point (transmission reception point, TRP), transmission contact (transmission point, TP), evolved Node B (eNB), radio network controller (radio network controller, RNC), node B (Node B, NB), base station controller (base station controller, BSC), base transceiver station (base transceiver station, BTS), home base station (e.g., home evolved NodeB, or home Node B, HNB), baseband unit (BBU), or wireless fidelity (wireless fidelity, wifi) Access Point (AP), etc.

The access and mobility management function network element AMF may be used for managing access control and mobility of the terminal device, and in practical application, it includes mobility management functions in a mobility management entity (mobility management entity, MME) in a network frame in long term evolution (long term evolution, LTE), and adds access management functions, which may be specifically responsible for registration, mobility management, tracking area update procedure, reachability detection, selection of session management function network elements, mobility state transition management, and so on of the terminal device. For example, in 5G, the access and mobility management function element may be a AMF (access and mobility management function) element, such as shown in fig. 4, and in future communications, such as 6G, the access and mobility management function element may still be an AMF element, or have other names, which is not limited by the present application. When the access and mobility management function network element is an AMF network element, the AMF may provide Namf services.

The location management function network element LMF, which may also be referred to as a location server, may be used to determine the location of the UE, obtain downlink location measurements or location estimates from the UE, etc. For example, in 5G, the location management function element (location management function, LMF) is shown in fig. 4, and in future communication systems, such as 6G, the location management function element may be an LMF element, or have other names, which is not limited by the present application.

Referring to fig. 5, an exemplary flowchart of a measurement reporting method for aperiodic PRS provided in an embodiment of the present application may include the following steps.

Step 501: and the terminal equipment receives the PRS configuration information.

The PRS configuration information may be sent to the terminal device by a network device that is providing services to the terminal device or may be sent to the terminal device by an LMF. The LMF may request the network device to report PRS configuration information when receiving the positioning request information.

The PRS configuration information may include information such as a bandwidth, a period, and a number of symbols of PRS. In addition, a resource type may be included, where the resource type may be used to indicate a type of PRS. The resource types may include periodic, semi-static, and aperiodic, among others. The resource type in the PRS configuration information is aperiodic. It should be understood that, in the embodiment of the present application, other information included in PRS configuration information may refer to the prior art, and the present application only focuses on describing the configuration information of the above PRS configuration information as non-periodic PRS configuration information.

Step 502: the network device sends the first value to the terminal device, and the corresponding terminal device receives the first value.

The first value may be used to indicate reporting configuration information of n aperiodic PRSs of the terminal device. The reporting configuration information of one aperiodic PRS may include reporting time information of m aperiodic PRSs. Where n and m are integers greater than 0.

Step 503: the terminal equipment receives PRS based on PRS configuration information.

The terminal device may receive PRS sent by the network device based on PRS configuration information. The terminal device may receive PRSs sent by the plurality of network devices according to the plurality of PRS configuration information.

In one example, the terminal device may measure the received PRS to obtain a measurement result. The measurement result may be a signal-to-interference-and-noise ratio (signal to interference plus noise ratio, SINR) of PRS, a reference signal received power (reference signal receiving power, RSRP), a reference signal received quality (reference signal receiving quality, RSRQ), a relative time of arrival (relative time of arrival, RTOA), or an angle of arrival (AOA). Alternatively, the measurement result may be a quantized result of the above-described plurality of measurement amounts.

Step 504: and the terminal equipment reports the measurement report of the PRS based on the received PRS.

The terminal device may report the measurement report of the PRS based on one of the reporting time information of the n×m aperiodic PRS. The measurement report of PRS herein may contain the measurement result of PRS. Alternatively, the terminal device may report the measurement report of the PRS to the network device, or the terminal device may send the measurement report of the PRS to the LMF.

The first value will be explained and explained first.

The first value may be used to indicate an aperiodic trigger state, where each aperiodic trigger state may be associated with one or more aperiodic PRS reporting configuration information. The network device may send the first value to the terminal device via DCI. For example, a new field "PRS request (PRS request)" is added in DCI format 0_1/0_2 for indicating an aperiodic trigger state. In the following, signalling one carrying the above first value is described. The signaling one may contain the following information elements:

1. the aperiodic prstriggerstatelist is interpreted as an aperiodic trigger state table. Wherein, the value (SEQUENC) of the apersidioPRSTriggerStateList is defined as the first value, and is interpreted as the aperiodic trigger state indicated by the first value in the aperiodic trigger state table. The first value may range from 1 to the maximum value of the values of the aperiodic trigger state (maxNrofPRS-TriggerStates).

2. The aperiodic prstriggerstatelist is interpreted as an aperiodic trigger state indicated by the first value described above. Wherein, the value (SEQUENC) of the aperiodic PRSTriggerStateList is used for one or more PRSReportConfigList indicating aperiodic PRS reporting configuration information. The PRS reporting configuration information table may include one or more values, where each value may be used to indicate one aperiodic PRS reporting configuration information. The range of the value of the PRS reporting configuration information may be from 1 to the maximum value of the aperiodic PRS reporting configuration information (maxnrofreportconfigperaeriodictrigger).

It should be noted that, the one or more aperiodic PRS reporting configuration information tables may be configured to the terminal device by the network device before triggering the aperiodic PRS reporting. For example, the network device may indicate one or more aperiodic PRS reporting configuration information to the terminal device via higher layer signaling. In the following, a second signaling carrying aperiodic PRS reporting configuration information is described. The second signaling may include the following information elements:

1. PRSReportConfig, interpreted as aperiodic PRS reporting configuration information. Wherein, one aperiodic PRS report configuration information corresponds to one value.

2. reportsloffsetlist, interpreted as an aperiodic PRS report slot offset table. The table may include one or more values, each of which may indicate an aperiodic PRS reporting slot offset. The aperiodic report slot offset herein refers to a slot offset between a slot in which a measurement report of an aperiodic PRS is reported and a signaling triggering an aperiodic PRS measurement is received. Alternatively, the aperiodic PRS reporting slot offset table may also be a transmission schedule of measurement reports of the aperiodic PRS, where each value in the table may be used to indicate a transmission time of a measurement report of one aperiodic PRS.

Optionally, the second signaling may further include an identifier of the downlink PRS resource set, an identifier of the downlink PRS resource, and so on. The identifier of the downlink PRS resource set is used to indicate the downlink PRS resource set configured by the network device, and the identifier of the downlink PRS resource may be used to indicate the downlink PRS resource that may be received by the terminal device in the downlink PRS resource set.

In one possible implementation, the network device may trigger the terminal device to receive the aperiodic PRS through the signaling described above, and report a measurement report of the aperiodic PRS.

The time for the terminal device to report the measurement report of the aperiodic PRS will be described below. The terminal device may determine, according to the reporting configuration information of the n aperiodic PRSs indicated by the first value and the reporting time information of the m aperiodic PRSs included in the reporting configuration information of each aperiodic PRS, a time for reporting a measurement report of the aperiodic PRS. Wherein the terminal device may receive the second value from the network device. The second value may be used to indicate transmission time information of communication data of the terminal device. For example, the second value may be a value of a time domain resource allocation field in the DCI. The terminal device may determine, according to the second value, one aperiodic PRS reporting time information from the n×m aperiodic PRS reporting time information. The aperiodic PRS reporting time information may be a transmission time of a measurement report of the aperiodic PRS or may be time difference information between a transmission time of a measurement report of the aperiodic PRS and a reception time of a first value. The terminal device may determine a transmission time of a measurement report of the aperiodic PRS based on the determined one aperiodic PRS reporting time information. Alternatively, the second value may be a transmission time of communication data indicated by the network device.

In one possible implementation, when n is equal to 1, the terminal device determines, from m pieces of aperiodic PRS reporting time information included in the reporting configuration information of one aperiodic PRS indicated by the first value, one aperiodic PRS reporting time information indicated by the second value. The value of the second value may be defined as j, and the information of reporting time of one aperiodic PRS indicated by the second value may be information of reporting time of the jth aperiodic PRS. For example, the reporting configuration information of one aperiodic PRS indicated by the first value includes m aperiodic PRS reporting time information (a 1, a2, a3, a4, a5, a 6), respectively, and the second value is 3, and then the aperiodic PRS reporting time information indicated by the second value may be a3.

In another possible implementation manner, when n is greater than 1, the terminal device may determine the aperiodic PRS reporting time information indicated by the n second values from the n aperiodic PRS reporting time information, respectively. The terminal device may select one aperiodic PRS reporting time information from the n aperiodic PRS reporting time information. Optionally, the terminal device may randomly select one aperiodic PRS reporting time information from the n aperiodic PRS reporting time information, or the terminal device may select one aperiodic PRS reporting time information with a maximum value from the n aperiodic PRS reporting time information. For example, the first value indicates reporting configuration information of three aperiodic PRSs, A1, A2, and A3, respectively. The aperiodic PRS reporting time information included in A1 may be (A1, A2, A3, a4, a5, a 6), the aperiodic PRS reporting time information included in A2 may be (b 1, b2, b3, b4, b 5), and the aperiodic PRS reporting time information included in A3 may be (c 1, c2, c3, c4, c5, c 6). The second value may be 4, and the terminal device may determine three aperiodic PRS reporting time information, a4, b4, and c4 according to the second value. The terminal device may randomly select one aperiodic PRS reporting time information in a4, b4, and c4, and determine a transmission time of a measurement report of the aperiodic PRS according to the selected one aperiodic PRS reporting time information. For example, the terminal device may select a4, and determine a transmission time of the measurement report of the aperiodic PRS according to a 4. Or the terminal equipment can select the aperiodic PRS reporting time information with the maximum value in a4, b4 and c4, and determine the sending time of the measurement report of the aperiodic PRS according to the aperiodic PRS reporting time information with the maximum value. For example, a4 < b4 < c4, the terminal device may determine the transmission time of the measurement report of the aperiodic PRS according to c4.

Optionally, assuming that the second value is 6, since A2 includes 5 aperiodic PRS reporting time information, that is, there is no 6 th aperiodic PRS reporting time information, the terminal device may determine two aperiodic PRS reporting time information, a6 and c6, in A1, A2 and A3. The terminal equipment can select one aperiodic PRS reporting time information in a6 and c6 to further determine the sending time of the measurement report of the aperiodic PRS, or can select one aperiodic PRS reporting time information with the largest value in a6 and c6 to further determine the sending time of the measurement report of the aperiodic PRS.

The terminal device may determine the transmission time of the measurement report of the aperiodic PRS according to the determined reporting time information of the one aperiodic PRS. The method for determining the sending time of the measurement report of the aperiodic PRS by the terminal device may include the following two methods. In the following embodiments, the determined one aperiodic PRS reporting time information may be defined as P.

And firstly, the terminal equipment is not triggered to report the aperiodic CSI.

If the terminal device is not triggered to report the aperiodic CSI within the preset duration, the sending time of the measurement report of the aperiodic PRS may be determined according to the sending time of the communication data to be transmitted of the terminal device and the determined information of the reporting time of the aperiodic PRS. The preset duration may be a duration between the time when the terminal device receives the first value and the time when the terminal device reports the measurement report of the aperiodic PRS. Or if the signaling carrying the first value does not trigger the aperiodic CSI reporting, the terminal device may determine the sending time of the measurement report of the aperiodic PRS according to the sending time of the communication data to be transmitted and the determined information of the reporting time of the aperiodic PRS.

In one example, if the terminal device has communication data to transmit at the time indicated by the second value, the terminal device may select a value with a larger value from the determined one aperiodic PRS reporting time information and the second value. The terminal device may send a measurement report of the aperiodic PRS based on the selected larger one of the values.

For example, referring to fig. 6A, the terminal device receives DCI from the network device in slot n, the DCI scheduled PUSCH has communication data transmission on and the DCI triggers aperiodic PRS reporting. Wherein, the second value K2 is indicated in the DCI. The PUSCH transmission slot carrying the measurement report of the aperiodic PRS may be determined by n+max (K2, P). Assuming K2 > P, the terminal device may send PUSCH carrying measurement reports of aperiodic PRS on slot n+k2.

Alternatively, the transmit slot for the measurement report carrying the aperiodic PRS may be determined by max (K2, P). Assuming K2 > P, the terminal device may send PUSCH carrying measurement reports of aperiodic PRS on K2. Optionally, the PUSCH may also carry communication data of the terminal device.

In another example, if the terminal device has no communication data transmission at the time indicated by the second value, the terminal device may send a measurement report of the aperiodic PRS based on the determined one aperiodic PRS reporting time information.

For example, referring to fig. 6B, the terminal device receives DCI from the network device in slot n, the DCI schedules PUSCH without communication data transmission and the DCI triggers aperiodic PRS reporting. The PUSCH transmission time instant for carrying the measurement report of the aperiodic PRS is determined by n+p. Wherein, the terminal device may send PUSCH carrying measurement reports of aperiodic PRS on time slot n+p.

Alternatively, the transmit slot for the measurement report carrying the aperiodic PRS may be determined by P. Wherein, the terminal device may send PUSCH carrying measurement reports of aperiodic PRS on time slot P.

And triggering the terminal equipment to report the aperiodic CSI.

If the terminal device is triggered to report the aperiodic CSI within the preset duration, the terminal device may determine the transmission time of the measurement report of the aperiodic PRS according to the time for reporting the aperiodic CSI, the transmission time of the communication data to be transmitted, and the determined one aperiodic PRS reporting time information. The preset duration may be described in the first method. Or if the signaling carrying the first value triggers the aperiodic CSI reporting, the terminal device may determine the sending time of the measurement report of the aperiodic PRS according to the time for reporting the aperiodic CSI, the sending time of the to-be-transmitted communication data, and the determined one aperiodic PRS reporting time information.

It should be noted that, the method for determining the reporting time of the aperiodic CSI may be the same as the method for reporting time information of the aperiodic PRS in the embodiment of the present application. For example, the network device may determine reporting configuration information of one or more aperiodic CSI for the terminal device. The reporting configuration information of each aperiodic CSI may include k reporting times of the aperiodic CSI. If the network device determines reporting configuration information of one aperiodic CSI for the terminal device, the terminal device may select a corresponding reporting time of one aperiodic CSI from the k reporting times of the aperiodic CSI according to the second value. If the network device determines the reporting configuration information of y aperiodic CSI for the terminal device, the terminal device may select the reporting time of the aperiodic CSI indicated by the y second values from the reporting times of k×y aperiodic CSI. The terminal device may select a maximum reporting time of the aperiodic CSI from among the reporting times of the y aperiodic CSI.

In one example, if the terminal device has communication data to transmit at the time indicated by the second value, the terminal device may determine a larger value among the second value and the fourth value. The fourth value here may be the sum of the third value and the time indicated by the determined one aperiodic PRS reporting time information P; the third value may be an offset of n from a time slot for reporting aperiodic CSI indicated in the CSI request field, or the third value may be a time slot for reporting aperiodic CSI indicated in the CSI request field. The terminal device may determine a transmission time of the measurement report of the aperiodic PRS according to a larger one of the second value and the fourth value.

For example, referring to fig. 7A, the terminal device receives DCI from the network device in time slot n, the DCI scheduled PUSCH has communication data transmission and triggers aperiodic PRS reporting and aperiodic CSI reporting. Wherein, the second value K2 is indicated in the DCI. The third value Y is also indicated in the DCI above. The transmission slot of PUSCH carrying measurement reports of aperiodic PRS may be determined by n+max (K2, y+p). Assuming K2 < y+p, the terminal device may send PUSCH carrying measurement reports of aperiodic PRS on time slot n+y+p.

Alternatively, the transmission slot of PUSCH carrying measurement reports of aperiodic PRS may be determined by max (K2, y+p). Assuming K2 < y+p, the terminal device may send PUSCH carrying measurement reports of aperiodic PRS on slot y+p. Optionally, the PUSCH may further include communication data and/or aperiodic CSI. It should be appreciated that the timing of receiving the CSI-RS and receiving the PRS in fig. 7A is exemplary and is not limited to the terminal device receiving the CSI-RS first and then the PRS, or to the terminal device receiving the PRS first and then the CSI-RS.

In another example, if the terminal device has no communication data transmission at the time indicated by the second value, the terminal device may determine a transmission time of the measurement report of the aperiodic PRS according to the fifth value. The fifth value may be the sum of the determined one aperiodic PRS reporting time information P and the third value Y.

For example, referring to fig. 7B, the terminal device receives DCI from the network device in time slot n, the DCI scheduled PUSCH has no communication data transmission and triggers aperiodic PRS reporting and aperiodic CSI reporting. Wherein, the second value K2 is indicated in the DCI. The third value Y is also indicated in the DCI above. The transmission slot of PUSCH carrying measurement reports of aperiodic PRS may be determined by n+y+p. The terminal device may send PUSCH carrying measurement reports of aperiodic PRS on slot n+y+p.

Alternatively, the transmission slot of the PUSCH carrying the measurement report of the aperiodic PRS may be determined with y+p. The terminal device may send PUSCH carrying measurement reports of aperiodic PRS on slot y+p. Optionally, the PUSCH may further include communication data and/or aperiodic CSI. It should be appreciated that the timing of receiving the CSI-RS and receiving the PRS in fig. 7B is exemplary and is not limited to the terminal device receiving the CSI-RS first and then the PRS, or to the terminal device receiving the PRS first and then the CSI-RS.

Based on the first and second methods, the transmission time of the measurement report of the aperiodic PRS of the terminal device in different situations can be as shown in table 1 below.

TABLE 1

Alternatively, the transmission time of the measurement report of the aperiodic PRS determined by the terminal device based on the first and second methods may be the transmission time of the measurement report of the aperiodic PRS that the terminal device actually transmits. Alternatively, a time offset may be set between the actual time when the terminal device transmits the measurement report of the aperiodic PRS and the determined transmission time. For example, the terminal device determines, based on the first and second methods, that the transmission time of the measurement report of the aperiodic PRS is n+y+p, and the actual time for the terminal device to transmit the measurement report of the aperiodic PRS may be n+y+p+offset. The offset here is a value of the time offset, which may be transmitted by the network device to the terminal device, or may be specified by a protocol, or may be negotiated by the network device and the terminal device.

The network device may receive the measurement report of the aperiodic PRS from the terminal device at the transmission time of the measurement report of the aperiodic PRS or at the actual transmission time of the measurement report of the aperiodic PRS. The network device may send the measurement results of the aperiodic PRS to the LMF. The LMF may process to obtain location information of the terminal device based on the measurement result of the aperiodic PRS. The LMF can adopt an UL-AOA positioning technology or an UL-TDOA positioning technology to process and obtain the position information of the terminal equipment. It should be noted that, the LMF may also determine the location information of the terminal device by using other positioning technologies, and the present application is not limited specifically.

Based on the above scheme, the network device can trigger the terminal device to perform aperiodic PRS reporting through DCI. The terminal device may determine a transmission time of the measurement report of the aperiodic PRS according to one or more of a communication data transmission time, an aperiodic CSI reporting time, and an aperiodic PRS reporting time. Therefore, when the aperiodic CSI report and the aperiodic PRS report are triggered simultaneously, the terminal device can have enough time to receive and measure the PRS, so that the positioning accuracy can be improved, and the positioning performance of the aperiodic PRS can be improved.

In one possible implementation, the terminal device may send the first capability information to the positioning server and/or the network device. The first capability information here includes positioning that the terminal device supports aperiodic PRS. Optionally, the first capability information may also include a processing capability of the terminal device for PRS, a measurement capability of the terminal device for PRS, and so on.

In another possible implementation, the terminal device may send the second capability information to the positioning server and/or the network device. The second capability information may be used to indicate that the terminal device supports simultaneous triggering of aperiodic CSI reporting and aperiodic PRS reporting, or the second capability information may be used to indicate that the terminal device does not support simultaneous triggering of aperiodic CSI reporting and aperiodic PRS reporting. Optionally, if the terminal device supports aperiodic CSI reporting and aperiodic PRS reporting, the network device may trigger the terminal device to perform aperiodic PRS reporting and aperiodic CSI reporting through one DCI.

If the terminal equipment does not support the simultaneous triggering of the aperiodic CSI and the aperiodic PRS, the network equipment can not trigger the terminal equipment to report the aperiodic CSI when triggering the terminal equipment to report the aperiodic PRS through one DCI. For example, the DCI triggering the terminal device to perform aperiodic PRS reporting does not include the CSI request field or the third value.

In one example, when the terminal device does not support simultaneous triggering of aperiodic CSI and aperiodic PRS, the transmission time of the measurement report of the aperiodic PRS may be shown in table 2 below.

The method for reporting the measurement of the aperiodic PRS provided by the present application is described below by way of specific embodiments.

Example 1,

Referring to fig. 8, an exemplary flowchart of a measurement reporting method for aperiodic PRS provided in an embodiment of the present application may include the following steps:

step 801, LMF receives a location request message.

The location request information here may be used to request location information of the terminal device. The location request information may be sent by the terminal device, or may be initiated by a third party server that wants to obtain location information of the terminal device. The location request information may be a location service request (location service request) message or may be a new definition message.

Step 802, the LMF sends a location capability request message to the terminal device.

The location capability request message here may be used to request location capability information of the terminal device. Wherein the LMF may send the location capability request message to the terminal device through a long term evolution location protocol (long term evolution positioning protocol, LPP) message. The positioning capability request message may be an LPP request capability (request capabilities) message or may be a new definition message.

Step 803, the terminal device sends the first capability information to the LMF.

Optionally, the terminal device may also send the second capability information to the LMF. The first capability information and the second capability information may be referred to the related description in the method embodiment shown in fig. 5, which is not described herein.

Step 804, LMF requests configuration information of the aperiodic PRS from the network device.

Wherein the LMF may send a transmission reception point (transmission and reception point, TRP) information (information) request (request) message to the network device. The TRP information request message may be used to request the network device to report configuration information for the aperiodic PRS. Alternatively, the LMF may send configuration information of the aperiodic PRS to the terminal device.

Step 805, the network device sends configuration information of the aperiodic PRS to the LMF.

The configuration information of the aperiodic PRS may be referred to as related description in the method embodiment shown in fig. 5, and will not be described herein. Alternatively, the LMF may send configuration information of the aperiodic PRS to the terminal device, or the network device may send configuration information of the aperiodic PRS to the terminal device.

Step 806, the network device sends DCI to the terminal device.

The DCI here may be used to trigger the terminal device to perform aperiodic PRS reporting. The DCI may include a first value. Optionally, the DCI may further include a second value and a third value. The DCI may refer to descriptions related to signaling one and signaling two in the method embodiment shown in fig. 5, which are not described herein.

Step 807: the network device transmits the aperiodic PRS, and the corresponding terminal device receives the aperiodic PRS.

Wherein the plurality of network devices may broadcast the aperiodic PRS, and the terminal device may receive the aperiodic PRS from the plurality of network devices.

Step 808, the terminal device measures the received aperiodic PRS.

The terminal device may receive PRSs from one or more network devices according to configuration information of aperiodic PRSs from the network device or from the LMF and measure the received PRSs.

Step 809, the terminal device sends a measurement report of the aperiodic PRS to the network device.

The terminal device may carry measurement reports of aperiodic PRS on PUSCH. The transmission time of the measurement report of the aperiodic PRS may be referred to as related description in the method embodiment shown in fig. 5, and will not be described herein.

Step 810, the network device sends measurement results of the aperiodic PRS to the LMF.

And 811, the LMF processes and obtains the position information of the terminal equipment according to the measurement result of the aperiodic PRS.

The LMF can adopt an UL-AOA positioning technology or an UL-TDOA positioning technology to process and obtain the position information of the terminal equipment. It should be understood that the LMF may also use other positioning technologies to obtain the location information of the terminal device, and the present application is not limited in particular.

The embodiment of the application provides a time sequence logic relation when the aperiodic PRS is reported, so that the terminal equipment and the base station have unified understanding on the PUSCH when to transmit the measurement report carrying the aperiodic PRS. For example, if the DCI only triggers reporting of the aperiodic PRS, the time slot in which the PUSCH carrying the measurement report of the aperiodic PRS is located may be determined by the aperiodic PRS reporting time information, which may allow the UE enough time to measure the aperiodic PRS. For the scenario that the aperiodic CSI and the aperiodic PRS reporting are triggered simultaneously, the terminal device needs to measure not only the CSI-RS but also the PRS, and both also need to be measured in a time-sharing manner, so that enough time needs to be reserved for the terminal device to measure, and therefore, the reporting time needs to be determined by the aperiodic CSI reporting time information and the aperiodic PRS reporting time information. Thus, the integrity of the CSI-RS measurement can be improved, and the positioning accuracy of the aperiodic PRS can be improved.
