In the description of the present invention, the term "plurality" means two or more unless otherwise specified.
Location-based services and emergency call positioning drive the development of positioning in wireless networks. Positioning support in third generation partnership long term evolution is introduced in release 9. This enables the operator to retrieve location information for location-based services and meet regulatory emergency call positioning requirements. Global positioning system enabled terminals are able to meet the requirements for positioning, but they do not provide the required availability due to the satellite signals being blocked in urban and indoor environments. Accordingly, other techniques are needed in such environments.
In LTE, OTDOA is a terminal-assisted method by observing the arrival time differences, and the terminal estimates the arrival time differences of positioning reference signals from different base stations, and these reference signal time difference measurements are quantized and reported to E-SMLC (Evolved Serving Mobile Location center) via LPP (light Presentation Protocol) together with accuracy estimates. Based on the known locations of the base stations and their mutual time synchronization, the E-SMLC uses multipoint positioning to estimate the terminal location from reference signal time difference measurements and covariance reports. The accuracy depends on the radio conditions of the received signals, the number of received signals, and the deployment, which means that it will be spatially different.
However, in OTDOA, the terminal is required to detect multiple adjacent cell signals, but these signals suffer from poor testability. However, no positioning reference signal design exists in the current 5G NR, and a terminal-assisted positioning technology and a corresponding measurement process are not supported yet.
Therefore, the embodiment of the invention provides a positioning reference signal for positioning measurement and a reference symbol for RRM measurement, and the positioning measurement is carried out by virtue of the terminal.

in the first mode, the positioning request information sent by the positioning node to the network side device contains a specific configuration value.
Specifically, the positioning node sends the positioning request message to the network side device, the network side device determines whether the configuration value in the positioning request message is available when replying the positioning response message, if so, the network side device can directly reply the specific configuration value in the positioning request message received before or reconfigure and reply to the positioning node through the positioning response message, and if not, the network side device reconfigures and replies to the positioning node through the positioning response message.
For example, the positioning request information sent by the positioning node to the network side device is: the PRS bandwidth of the cell positioning reference signal is 10MHz, the SSB transmission period is 80ms, the offset value is 20ms, and the duration is 2ms, the network side device determines that these configuration values are available, and replies to the positioning node through the positioning response information after confirming these configuration values, or reconfigures, for example, the positioning response information that the network side device replies to the positioning node after reconfiguring is: the PRS bandwidth of the cell positioning reference signal is 10MHz, the SMTC sending period is 60ms, the offset value is 20ms, and the duration is 2 ms.
And in the second mode, the positioning request information sent by the positioning node to the network side equipment does not contain a specific configuration numerical value.
Specifically, the network side device receives the positioning request information sent by the positioning node, and replies the positioning request information to the positioning node after the positioning request information only includes the configuration request information requesting the network side to configure the cell positioning reference signal and the SSB, but does not include the specific configuration values of the cell positioning reference signal and the SSB, that is, only includes the cell ID and the corresponding configuration request information.
For example, a positioning node sends positioning request information to a network side device, where the positioning request information includes configuration request information of a cell positioning reference signal PRS bandwidth, an SSB sending period, an offset value, and a duration, and the positioning node requests the network side device to reply specific configuration information, for example, positioning response information replied by the positioning node is: the PRS bandwidth of the cell positioning reference signal is 10MHz, the SSB sending period is 60ms, the offset value is 20ms, and the duration is 2 ms.
It should be noted that, the manner in which the positioning node and the network side device perform the positioning request and the positioning response in the embodiment of the present invention is only an example, and any manner in which the positioning node and the network side device perform the positioning request and the positioning response is applicable to the embodiment of the present invention.
In the embodiment of the present invention, after receiving the positioning response information containing the SSB configuration information sent by the network side device, the positioning node determines the positioning assistance data according to the received positioning response information.
In an embodiment of the invention, the positioning assistance data comprises part or all of the following:
physical cell ID, positioning reference signal configuration information, measurement interval configuration information, BWP configuration information.
Wherein the measurement interval configuration information includes, but is not limited to, some or all of the following:
a measurement interval period for positioning measurements, an offset value, a measurement interval length for positioning measurements, a measurement interval sharing factor for positioning measurements.
Wherein the BWP configuration information includes, but is not limited to, some or all of the following:
frequency domain location of BWP, bandwidth, identifier of BWP.
For example, the positioning response information containing the SSB configuration information, which is received by the positioning node and sent by the network side device, is: the PRS bandwidth of the cell positioning reference signal is 10MHz, the SSB sending period is 60ms, the deviant is 20ms, the duration is 2ms, and the positioning node determines the positioning auxiliary data as follows according to the received positioning response information: the measurement interval period for positioning measurement is 10ms, and the measurement interval length for positioning measurement is 10 ms.
There are many ways in determining the physical cell ID, several of which are listed below:
in the first mode, the positioning node can select the cells with the same frequency domain position and different time domain transmission positions of the SSB and the PRS in the same frequency cell, and the cells with the same frequency domain position allow the terminal to measure, so that the terminal can be ensured not to conflict when RRM and positioning measurement are carried out.
As shown in fig. 2, there are 3 cells with the same frequency, which are cell 1, cell 2, and cell 3, respectively, where SSB and PRS of the 3 cells have different time domain transmission positions, but have the same frequency domain position, the 3 cells may be selected to allow the terminal to perform measurement, and the 3 cell IDs are transmitted to the terminal through the positioning assistance data.
And secondly, the positioning node can select SSB and PRS time domain sending positions to be overlapped and frequency domain positions to send different cells to measure by the terminal.
Optionally, a BWP including the SSB and PRS frequency-domain transmission positions may be configured according to the SSB and PRS frequency-domain transmission positions, so as to ensure that a measurement interval can simultaneously perform RRM measurement and positioning measurement.
As shown in fig. 3, the transmission positions of the SSB and PRS of the cell 1 in the frequency domain are shown, and the black part in the figure is the currently active BWP, where a part of the bandwidth of the currently active BWP overlaps with the SSB bandwidth, a part of the bandwidth overlaps with the PRS bandwidth, the bandwidth of the currently active BWP is greater than that of the PRS bandwidth, and the transmission positions of the SSB and PRS of the cell 1 in the time domain are the same, then the RRM measurement and the positioning measurement can be performed simultaneously in the same measurement interval, and the positioning node transmits the ID of the cell 1 to the terminal through the positioning assistance data.
In a third mode, the positioning node may select a cell with non-overlapping SSB and PRS time domain transmission positions in the inter-frequency cell to allow the terminal to perform measurement, so that the terminal may need different measurement intervals to perform RRM measurement and positioning measurement, and at this time, the positioning node may configure a measurement interval for the terminal to perform positioning measurement.
As shown in fig. 4, 3 inter-frequency cells in the diagram are cell 1, cell 2, and cell 3, and the SSB and PRS time domain transmission positions of the 3 cells are not overlapped, then the 3 cells may be selected to allow the terminal to perform measurement, and the 3 cell IDs are transmitted to the terminal through the positioning assistance data. Alternatively, the terminal needs different Measurement intervals to perform the RRM Measurement and the positioning Measurement, where MG1(Measurement Gap1, first Measurement interval) represents a first Measurement interval for the RRM Measurement, and MG2(Measurement Gap 2, second Measurement interval) represents a second Measurement interval for the positioning Measurement.
It should be noted that the manner for determining the physical cell ID in the embodiments of the present invention is only an example, and any manner capable of determining the physical cell ID is applicable to the embodiments of the present invention.
In the embodiment of the invention, after receiving the message for starting the positioning measurement sent by the high layer, the terminal sends the indication information for starting the positioning measurement to the network side equipment.
For example, after receiving a message for starting positioning measurement sent by a positioning protocol layer, the terminal sends instruction information for starting positioning measurement to the network side device, where the instruction information for starting positioning measurement is various, and several examples are listed below.
And indicating information I, and starting positioning measurement of a required measurement interval.
If the positioning measurement needs to use a measurement interval, and the network-side device does not configure a measurement interval for the terminal at this time, or the configured measurement interval is invalid, for example, the configured measurement interval cannot perform the positioning measurement or does not include a valid positioning measurement reference signal, the terminal instructs the network-side device to "start the positioning measurement requiring the measurement interval".
Optionally, the terminal places measurement interval configuration information for assisting the network side device to configure the measurement interval in the indication information for starting the positioning measurement.
There are many ways for the terminal to configure the measurement interval configuration information for assisting the network side device to configure the measurement interval, and the following are listed as some:
in configuration mode 1, the positioning assistance data sent by the positioning node to the terminal includes measurement interval configuration information, and the terminal sends the measurement interval configuration information in the received positioning assistance data to the network side device.
For example, the positioning assistance data received by the terminal is: the bandwidth of the cell 1 positioning reference signal is 10MHz, the measurement interval period for positioning measurement is 10ms, and the measurement interval length for positioning measurement is 10ms, where the measurement interval period includes measurement interval configuration information for positioning measurement, and the terminal sends the measurement interval configuration information in the positioning assistance data to the network side device.
In configuration mode 2, the positioning assistance data sent by the positioning node to the terminal does not include measurement interval configuration information, and the terminal determines the required measurement interval configuration according to the received positioning assistance data and sends the measurement interval configuration to the network side device.
For example, the positioning assistance data received by the terminal is: a PRS bandwidth of a cell 1 positioning reference signal is 10MHz, a PRS transmission period is 10ms, a BWP bandwidth is 15MHz, and measurement interval configuration information for positioning measurement is not included therein, then the terminal determines a required measurement interval configuration according to the received positioning assistance data, for example, the terminal determines, according to the received PRS transmission period of the cell 1, configuration information for assisting a network side device to configure a measurement interval as follows: the measurement interval period for positioning measurement is 10ms, and the measurement interval length for positioning measurement is 10 ms.
It should be noted that, the manner in which the terminal configures the measurement interval configuration information for assisting the network-side device to configure the measurement interval recited in the embodiment of the present invention is merely an example, and any manner in which the terminal configures the measurement interval configuration information for assisting the network-side device to configure the measurement interval is applicable to the embodiment of the present invention.
Indication information two, start positioning measurement that needs to switch BWP.
If the positioning measurement needs to switch BWP, that is, the currently active BWP cannot perform positioning measurement, for example, the bandwidth of the currently active BWP is smaller than that of the PRS, or the location of the BWP does not include the PRS, the terminal instructs the network-side device to "turn on the positioning measurement that needs to switch BWP".
As shown in fig. 5A, the black part in the diagram represents the location of the currently active bandwidth, and the shaded part below the currently active BWP represents the location of the PRS frequency domain, and it can be known from the diagram that the positioning measurement cannot be performed in the currently active bandwidth, because the location of the BWP does not include the PRS, the terminal is required to instruct the network-side device to "turn on the positioning measurement that needs to switch BWP".
As shown in fig. 5B, the black part in the figure represents the position of the current active bandwidth, the shaded part represents the position of the PRS frequency domain, the position of the current active bandwidth includes the PRS, and the bandwidth of the current active BWP is greater than that of the PRS, at this time, the terminal does not need to instruct the network-side device to "turn on the positioning measurement that needs to switch BWP", and if the terminal needs the network-side device to reconfigure BWP without using the current active bandwidth, the terminal may still instruct the network-side device to "turn on the positioning measurement that needs to switch BWP".
Optionally, the terminal places BWP configuration information for assisting the network-side device to configure BWP in the indication information for starting positioning measurement.
For example, if the BWP bandwidth required by the terminal is 10KHz and the center frequency point of the BWP is 5KHz, the terminal places the configuration information including the BWP bandwidth and the center frequency point in the indication information of the start positioning measurement, and may also place the difference between the BWP bandwidth and the currently activated BWP as the offset value offset in the indication information of the start positioning measurement.
In the embodiment of the invention, the network side equipment sends RRC message to the terminal after receiving the indication information for starting positioning measurement sent by the terminal.
Wherein the RRC message includes, but is not limited to, some or all of the following:
measurement interval configuration information, BWP configuration information.
Wherein the measurement interval configuration information includes, but is not limited to, some or all of the following:
a measurement interval period for positioning measurements, an offset value, a measurement interval length for positioning measurements, a measurement interval sharing factor for positioning measurements.

For example, the sharing factor is 25%, and of all measurement gap resources, 25% is used for performing intra-frequency measurement, and 75% is used for performing including positioning measurement.
