Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the embodiment of the invention, by combining the characteristics of the multi-beam NR system, when the measurement configuration operation is executed, the measurement configuration information carries the resource identification information of the target reference signal to be measured (i.e. which beam the target reference signal is located in), so that the terminal can perform more targeted and purposeful measurement instead of monitoring all beams and detecting monitored signals when the terminal executes the measurement operation, thereby improving the measurement efficiency.
The above measurement configuration can be applicable to measurement configuration for terminal positioning, and also applicable to other measurement configuration scenarios, such as a scenario for configuring signal quality measurement, and at this time, resource identification information may also be added to the signal quality measurement configuration issued by the network side, so as to implement signal quality measurement on a certain beam, rather than signal quality measurement of a cell.
Fig. 1 is a schematic flow chart of a measurement configuration method according to an embodiment of the present invention, where the method is applied to a network node. As shown in fig. 1, the measurement configuration method includes:
step 101, sending a first measurement configuration message, where the first measurement configuration message carries first resource identification information, and the first resource identification information is used to indicate a transmission resource carrying a target reference signal to be measured.
The transmission resource may be one beam or a part of beams in multiple beams sent by a network side node, the first measurement configuration message carries resource identification information corresponding to the beams one to one, and the beam corresponding to the resource identification information can be determined by identifying the resource identification information.
Therefore, after the base station or the network management server and other network side nodes send the multi-beam signals at the same time, each beam can be distinguished through the first resource identification information corresponding to the beams one by one, so that measurement and report in units of beams are achieved, and the accuracy of measurement results is improved.
In addition, after receiving the first measurement configuration message, the terminal may perform measurement indicated by the first measurement configuration message for a target reference signal, and report a measurement result in a manner associated with a transmission resource carrying the target reference signal. The measurement configuration is carried out by taking the wave beams as units, so that the pertinence of the measurement configuration method can be improved, and the method is more suitable for an NR system adopting a multi-beam technology.
In a specific embodiment of the present invention, the measurement configuration method may be used for terminal positioning, and when the measurement configuration method is used for terminal positioning, the first measurement configuration message further carries parameters to be measured, where the parameters to be measured include at least one of the following parameters: reference signal time difference, sending and receiving time difference, reference signal time delay and first path time delay.
Therefore, the positioning entity can more accurately position the terminal according to the measured values of the reference signal time difference, the sending and receiving time difference, the reference signal time delay and the first path time delay.
However, in the conventional positioning technology, the positioning server sends auxiliary information for positioning (including information such as a cell ID and a Reference Signal configuration for measurement) to the terminal, and requests location information, and the terminal starts measurement of RSTD (Reference Signal Time difference) or Rx-Tx Time difference (Time difference between transmission and reception), and reports the measurement result. Wherein, if the terminal only supports the measurement of the same-frequency RSTD, or under the condition of the existing measurement interval configuration of the different-frequency RSTD, the procedures are invisible to the base station. Only when the terminal needs to perform inter-frequency RSTD measurement and is not configured with a measurement interval yet, the terminal needs to trigger a Radio Resource Control (RRC) procedure to request the base station to configure the measurement interval of the inter-frequency RSTD.
In NR, due to the introduction of multiple beams, when the transmission beam direction of the reference signal is exactly aligned with the terminal, then due to the gain of beamforming, the terminal is likely to be able to detect the arrival time of this direct-view path; when the transmission beam of the reference signal deviates from the terminal, the terminal receives the reflected signal only when there is a scatterer in the direction that can form a reflected path to the terminal, and the arrival time is delayed compared with that of the direct-view path. Therefore, in NR, if a relatively suitable direct-view beam can be found and a positioning reference signal is sent to the terminal, the accuracy of estimating the arrival time of the reference signal by the terminal can be effectively improved.
However, in the existing NR channel state reporting framework, only the signal quality of the beam can be reported, and the time of arrival, the resolution direct view path, and the like of the signal on each beam cannot be determined, so that the measurement and reporting based on the beam cannot be performed in the existing positioning technology, and the positioning accuracy is reduced.
In the embodiment of the present invention, in the process of reporting the positioning measurement value of NR, reporting of indication information for a beam may be added, reporting for first path delay may be added in the process of reporting the channel state of NR, and an RRC procedure configured by a terminal triggering a base station may be added, so as to assist the base station to implement positioning based on the beam, and perform selection of a transmission beam of PRS (positioning reference Signals), thereby improving positioning accuracy of NR.
It should be noted that the parameter to be measured may be a parameter for measuring the service quality, in addition to the reference signal time difference, the transmission/reception time difference, the reference signal time delay, and the first path time delay, as described above, for example: received power, etc.
Further, the first measurement configuration message also carries at least one of the following information:
indication information for indicating a subcarrier spacing used by a reference cell reference signal to be measured;
indicating information for indicating a neighbor cell reference signal subcarrier spacing to be measured; and the number of the first and second groups,
indication information for indicating a reference subcarrier spacing.
In addition, if the Rx-Tx reception time difference is being measured, the subcarrier interval corresponding to the measured value may be the subcarrier interval of the reference cell to be measured; if the RSTD value is measured, the subcarrier spacing corresponding to the measured value may be based on the configured reference subcarrier spacing, that is, the reference subcarrier spacing configured by the positioning server, or may be the smaller value of the subcarrier spacing between the reference cell to be measured and its neighboring cells.
In addition, the network side node may be a network side device such as a base station and a positioning server.
It should be noted that the measurement configuration method may be applied to positioning of the terminal device, and may also be applied to other technical solutions such as improving quality of signal transmission, for example: according to the quality parameters of each beam obtained by measurement, the beam with the best transmission quality can be selected to serve the terminal, and the service quality is improved.
In the embodiment of the present invention, the above configuration may be performed for all available beams, but in order to improve efficiency, the available beams may also be screened, and the screened beams may be configured in a targeted manner, so that the terminal only measures the screened beams, thereby improving efficiency.
In the embodiment of the present invention, the screening process may be processed by combining the existing CSI (Channel state information) measurement and reporting process. That is, in the specific embodiment of the present invention, before step 101, the measurement configuration method may further include:
sending a second measurement configuration message to the terminal under the trigger of the terminal, where the second measurement configuration message is a channel state information measurement configuration message, the second measurement configuration message carries parameters to be measured, and the parameters to be measured include at least one of the following parameters: reference signal time difference, sending and receiving time difference, reference signal time delay and first path time delay;
receiving a channel state information measurement report message sent by a terminal, wherein the channel state information measurement report message carries a second measurement value of the parameter to be measured;
the target reference signal is a reference signal selected by the network side node according to the second measurement value.
The second measurement value may be a measurement result for at least one of a reference signal time difference, a transmission/reception time difference, a reference signal time delay, and a head path time delay, and beams with a smaller deflection between a transmission direction and a terminal may be determined according to the measurement result, and then reference signals to be measured are configured on the beams, so as to improve measurement pertinence and efficiency.
In a specific embodiment of the present invention, the first path delay is a time interval between the arrival time of the first path of the detected reference signal and the start time of the subframe or time slot or symbol in which the reference signal is located.
That is to say, in this embodiment, before the network side node sends the target reference signal to the terminal to be measured, the network side node selects the beam carrying the target reference signal to be measured from the multiple beams, so as to avoid the terminal performing invalid measurement (for example, the measurement transmission direction completely deviates from the terminal or the beam greatly deflects from the terminal), and improve the measurement pertinence and efficiency.
In addition, in the NR system, in addition to Channel related information such as a CQI (Channel Quality Indicator), an RI (Rank Indication), and a PMI (Precoding matrix Indicator), a layer 1RSRP (L1 referred signal Receiving Power) may be reported in the report of the CSI, which is to report the beam Quality, and the beam selection may also be combined with these parameters, for example, when the RSRP measured on a certain reference signal is higher than a certain threshold, it means that the reception Quality of the terminal in the direction of the reference signal is good enough, and the terminal reports the information to the base station, which may be used for the base station to perform beam selection.
The first resource identification information is a resource indicator (Positioning reference signal) associated with a Positioning reference signal, and is used for associating with a transmission resource such as a beam.
As an alternative embodiment, the resource indication "referrencignalresourceindex" of the reference signal is added through the prsInfo field in the following code:
Figure BDA0001816177100000081
Figure BDA0001816177100000091
in the embodiment of the invention, a first measurement configuration message is sent to a terminal, wherein the first measurement configuration message carries first resource identification information, and the first resource identification information is used for indicating transmission resources carrying target reference signals to be measured. Thus, when the method is applied to the multi-beam technology, the first resource identification information can be used for indicating the beam carrying the target reference signal, so that the measurement method which takes the beam as a unit for measurement and reporting can be used for solving the problem that the measurement method which takes the cell as a unit for measurement and reporting is not suitable for an NR system.
Fig. 2 is a schematic flow chart of a measurement method according to an embodiment of the present invention, where the method is applied to a terminal. As shown in fig. 2, the measuring method includes the steps of:
step 201, receiving a first measurement configuration message, where the first measurement configuration message carries resource identification information, and the resource identification information is used to indicate a transmission resource carrying a target reference signal to be measured.
The first measurement configuration message may be a positioning measurement configuration message, the network side sends the positioning measurement configuration message, and adds indication information corresponding to the beam, and when the terminal reports a measurement result after the measurement is completed, the measurement result and the resource identification information may be associated, thereby implementing measurement in units of beams.
Of course, the above measurement can also be applied to other measurement scenarios, such as a scenario of measuring signal quality, and at this time, the resource identifier information may also be added to the signal quality measurement configuration received by the terminal, so as to implement signal quality measurement on a certain beam, instead of signal quality measurement of a cell.
In this step, the resource identifier information is added to the first measurement configuration message, so as to achieve the effect of distinguishing transmission resources.
Step 202, measuring the target reference signal on the transmission resource indicated by the resource identification information, and obtaining a first measurement value.
In the measurement process, the terminal only measures the transmission resource indicated by the resource identification information, and compared with the measurement taking the cell as a unit, the embodiment of the invention does not need to measure other reference signals of the cell, thereby improving the pertinence and the efficiency of the measurement process.
In addition, the terminal can report the measurement result to the network side node in a manner of being associated with the transmission resource carrying the target reference signal, and the measurement is performed by taking the beam as a unit, so that the pertinence of the measurement method can be improved, and the method is more suitable for an NR system adopting a multi-beam technology.
For example: the positioning server sends a positioning reference signal to be measured to the terminal based on the triggering of the terminal, and identifies the indication information of the beam carrying the positioning reference signal, the terminal measures the RSTD value or the Rx-Tx receiving time difference, and feeds back the measurement result and the indication information of the corresponding beam to the positioning server together, so that the positioning server can distinguish the measurement values corresponding to different reference signals, the network side can determine the measurement value corresponding to the beam with the minimum transmission distance to perform positioning, or select the beam with the best transmission quality to serve the terminal.
In this step, the terminal only measures on the corresponding transmission resource according to the received identification information, thereby avoiding measuring and reporting in a cell unit, and when the terminal is applied to an NR system using a multi-beam technology, the measurement result of each beam can be distinguished, thereby facilitating measuring and reporting of one or a part of beams among the multi-beams. And the network side can also select the beam to carry out corresponding processing according to different scenes, so that the processing precision is improved.
In a specific embodiment of the present invention, the measurement method may be used for terminal positioning, and when the measurement method is used for terminal positioning, the first measurement configuration message further carries parameters to be measured, where the parameters to be measured include at least one of the following parameters: reference signal time difference, sending and receiving time difference, reference signal time delay and first path time delay.
Thereby, the first measurement value comprises at least one of the following measurement values: the measurement value of the reference signal time difference, the measurement value of the sending and receiving time difference, the measurement value of the reference signal time delay and the measurement value of the first path time delay. And the positioning entity positions the terminal more accurately according to the measured values of the reference signal time difference, the sending and receiving time difference, the reference signal time delay and the first path time delay.
In the embodiment of the present invention, the above measurement may be performed for all available beams, but in order to improve efficiency, the available beams may be screened, and the screened beams may be measured in a targeted manner, so as to improve efficiency.
In the embodiment of the present invention, the screening process may be processed by combining the existing CSI (Channel state information) measurement and reporting process. That is, in the embodiment of the present invention, before step 201, the measurement method further includes:
receiving a second measurement configuration message sent by a network side node under the trigger of the terminal, where the second measurement configuration message is a channel state information measurement configuration message, and the second measurement configuration message carries parameters to be measured, where the parameters to be measured include at least one of the following parameters: reference signal time difference, sending and receiving time difference, reference signal time delay and first path time delay;
executing channel state information measurement to obtain a second measurement value of the parameter to be measured;
the target reference signal is a reference signal selected by the network side node according to the second measurement value.
In this embodiment, before the terminal triggers the network side node to send the target reference signal to the terminal to be measured, the terminal selects the beam carrying the target reference signal to be measured from the multiple beams, so as to avoid the terminal performing invalid measurement (for example, the measurement transmission direction deviates from the terminal completely or deflects from the terminal greatly), and improve the pertinence and efficiency of the measurement.
As an optional implementation manner, the terminal reports the measured RSTD value or Rx-Tx receiving time difference to the positioning server, wherein the RSTD value or Rx-Tx receiving time difference is associated with the PRS Resource index on the primary cell; is also associated with the neighbour ID and the neighbour PRS Resource index.
For example: the measurement reporting process for RSTD in LTE is as follows, and the specific embodiment of the present invention can add "referrencignalresource index" of the primary cell and the neighboring cell in this field, thereby realizing association between measurement and measurement result reporting and beams.
Figure BDA0001816177100000111
Figure BDA0001816177100000121
Figure BDA0001816177100000131
The method is applied to wireless positioning, the terminal reports the measured RSTD value, the Rx-Tx receiving time difference or the first path delay to a positioning server, and the measured result of the terminal is associated with the PRS resource identifier on the main cell by adding 'referreSignalResourceIndex' in a NotSameAsRef0 field and NotSameAsRef 2; or the measured value is associated with the neighboring cell ID and the neighboring cell PRS Resource index, and in addition, in the LET, the report of the measured value only needs to be associated with the neighboring cell ID.
In the embodiment of the present invention, the terminal performs measurement only for a transmission resource carrying a target reference signal according to the received first measurement configuration message, so as to obtain a first measurement value. When the terminal executes the measurement operation, the terminal can carry out more targeted and purposeful measurement instead of monitoring all the beams and detecting monitored signals, so that the measurement efficiency can be improved.
Please refer to fig. 3, which is a flowchart illustrating a measurement reporting method applied to a terminal according to an embodiment of the present invention, as shown in fig. 3, the method includes the following steps:
step 301, sending a first measurement report message, where the first measurement report message carries a first measurement value of a target reference signal and resource identifier information indicating a transmission resource carrying the target reference signal.
In this step, the terminal reports the measured value of the target reference signal in a manner of associating the measured value with the resource identification information carrying the target reference signal. Therefore, the network side node can determine which transmission resource the measured value is transmitted through according to the first measurement report message reported by the terminal, when the network side node is applied to the multi-beam technology, different measured values obtained aiming at each beam can correspond to the corresponding beam, the disorder of the measuring result of the multi-beam is avoided, and the network side node is more suitable for an NR system adopting the multi-beam technology.
In an embodiment of the present invention, the measurement configuration method may be used for terminal positioning, and when the measurement configuration method is used for terminal positioning, the first measurement value includes at least one of the following measurement values: the measurement value of the reference signal time difference, the measurement value of the sending and receiving time difference, the measurement value of the reference signal time delay and the measurement value of the first path time delay.
Therefore, the network side node can position the terminal more accurately according to the measured values of the reference signal time difference, the sending and receiving time difference, the reference signal time delay and the first path time delay.
Specifically, when the first measurement value is a measurement value of a reference signal time difference, the resource identification information includes: first resource identification information indicating resources carrying reference signals of a reference cell and second resource identification information indicating resources carrying reference signals of an adjacent cell;
alternatively, the first and second electrodes may be,
under the condition that the first measurement value is a measurement value of a sending and receiving time difference, a measurement value of a reference signal time delay or a measurement value of a reference signal first path time delay, the resource identification information includes: first resource identification information indicating resources carrying reference signals of a reference cell, or second resource identification information indicating resources carrying reference signals of a neighbor cell.
In the embodiment of the present invention, the measurement report described above may be performed for all available beams, but in order to improve efficiency, the available beams may also be screened, and the screened beams may be measured and reported in a targeted manner, so that the terminal only performs measurement and report on the screened beams, thereby improving efficiency.
In the embodiment of the present invention, the screening process may be processed by combining the existing CSI (Channel state information) measurement and reporting process. That is, in an embodiment of the present invention, before step 301, the method further includes:
sending a second measurement report message, where the second measurement report message is a channel state information measurement report message, and the second measurement report message carries a measurement value of a parameter to be measured, where the parameter to be measured includes at least one of the following parameters: reference signal time difference, sending and receiving time difference, reference signal time delay and first path time delay;
the target reference signal is a reference signal selected by the network side node according to the second measurement value.
In this embodiment, at least one of the reference signal time difference, the sending and receiving time difference, the reference signal time delay, and the first path time delay is measured and reported by the terminal, so that the network side node can determine the beams with smaller deflection between the transmission direction and the terminal according to the parameters, further bear the reference signals on the beams, instruct the terminal to measure the reference signals on the beams, and report the measurement results of the beams, so as to improve the pertinence and efficiency of measurement and measurement reporting.
As an optional implementation manner, the terminal triggers an RRC procedure, and requests the base station to configure the reported amount of channel measurement as "arrival time", or "arrival time + RSRP"; or the base station configures the channel measurement report quantity into 'first path arrival time', or 'first path arrival time + RSRP'. It is necessary to add beam-related reference information configuration, such as Resource indication (Positioning RS Resource index) of Positioning reference signals, to assist the base station to transmit PRS(s) with proper beams.
Specifically, the "First Path arrival time" (pri-First Detected Path) or "First Path arrival time + RSRP" (pri-First Detected Path-RSRP) may be added to the report message of the terminal by executing the following codes:
Figure BDA0001816177100000151
