Fig. 2A is an interactive schematic diagram illustrating a positioning measurement processing method according to an embodiment of the present disclosure. As shown in fig. 2A, an embodiment of the present disclosure relates to a positioning measurement processing method, where the method includes:

in step S2101, the access network device sends a first positioning reference signal to the terminal.

In some embodiments, the access network device may send the first positioning reference signal to the terminal on a plurality of first frequency layers for sending the first positioning reference signal.

Wherein a plurality of first frequency layers (frequency layers) for transmitting the first positioning reference signal are used for bandwidth aggregation of the first positioning reference signal. That is, the terminal may be a terminal configured with bandwidth aggregation.

In some embodiments, the terminal may monitor the first positioning reference signal in the plurality of first frequency layers to obtain a positioning measurement result of the terminal by measuring the first positioning reference signal.

Wherein the first positioning reference signal may be a positioning reference signal (Positioning Reference Signal, PRS). Alternatively, the first positioning reference signal may be sent by the access network device to the terminal. For example, the access network device may send PRSs to the terminal on a plurality of first frequency layers.

In step S2102, the terminal determines at least one second frequency layer among a plurality of first frequency layers for transmitting the first positioning reference signal.

It should be noted that the terminal may have the capability of receiving the first positioning reference signal on a plurality of first frequency layers, but the first frequency layers of the first positioning reference signal used for measurement may be different when different types of positioning measurement results are obtained.

In some embodiments, the terminal may determine at least one second frequency layer among the plurality of first frequency layers. Alternatively, the terminal may have the capability of actively selecting the second frequency layer, or the terminal may perform the determination of the second frequency layer according to the indication of the core network device.

In some embodiments, the terminal has the capability to actively select the second frequency layers, e.g. the terminal may determine at least one second frequency layer from the plurality of first frequency layers according to the type of positioning measurement to be obtained.

In some embodiments, the positioning measurement is a carrier phase positioning (carrier phase positioning, CPP) related positioning measurement, and the terminal may select one first frequency layer from the plurality of first frequency layers as the second frequency layer.

The CPP-related positioning measurement result represents a measurement result obtained by measuring the carrier phase of the reference signal by the terminal. Alternatively, the CPP-related positioning measurements may include reference signal phase (reference signal carrier phase, RSCP) and/or reference signal phase difference (reference signal carrier phase difference, RSCPD), but are not limited thereto, and the CPP-related positioning measurements may also include other types of positioning measurements, and the embodiments of the present disclosure are not limited thereto.

For example, the terminal may select one second frequency layer from the plurality of first frequency layers to measure a first positioning reference signal (e.g., PRS) to obtain RSCP and/or RSCPD.

Optionally, the terminal may select one first frequency layer from the plurality of first frequency layers as a second frequency layer based on a first default condition, where the second frequency layer may be used to measure a CPP-related positioning measurement result.

For example, the terminal may determine a default frequency layer (default frequency layer) from the plurality of first frequency layers based on the first default condition, such that the default frequency layer may be used as a second frequency layer for measuring CPP-related positioning measurements.

Alternatively, the first default condition may include any one of the following:

That is, default frequency layer may be a frequency layer corresponding to the first frequency (frequency) in the frequency list; alternatively, default frequency layer can be the lowest frequency layer among the plurality of first frequency layers; alternatively, default frequency layer can be the largest bandwidth frequency layer among the plurality of first frequency layers.

In some embodiments, the positioning measurement result is a CPP related positioning measurement result, and the terminal may further determine each of the plurality of first frequency layers as a second frequency layer, so that measurement of the first positioning reference signal may be performed on each second frequency layer.

For an introduction of the CPP related positioning measurement result, reference may be made to the above embodiment, and details are not repeated here.

In some embodiments, the positioning measurement is a non-time dependent positioning measurement, and the terminal may select at least one first frequency layer from the plurality of first frequency layers as the second frequency layer.

The time-dependent positioning measurement result may include at least one of reference signal time difference (reference signal time difference, RSTD), terminal reception-transmission time difference (user equipment receive-transport time difference, UE Rx-Tx time difference), time of arrival (TOA), but is not limited thereto, and may include other types of positioning measurement results. It should be noted that other positioning measurements than those listed above are non-time dependent positioning measurements.

In some embodiments, the positioning measurement is a non-CPP related positioning measurement, the terminal may select at least one first frequency layer from the plurality of first frequency layers as the second frequency layer, or the terminal may determine the second frequency layer according to a bandwidth aggregation configuration of the first positioning reference signal.

Alternatively, the terminal may determine by what manner to determine the second frequency layer to use to obtain the non-CPP related location measurement result according to the protocol convention, or the terminal may freely select by what manner to determine the second frequency layer to use to obtain the non-CPP related location measurement result based on the implementation.

The non-CPP related positioning measurements may include, among other things, at least a reference signal received power (reference signal received power, RSRP) and/or a reference signal received path power (reference signal received path power, RSRPP). Optionally, the non-CPP related positioning measurement may further include a time related positioning measurement, for example, the non-CPP related positioning measurement may further include an angle of arrival (AOA).

For example, the terminal may select at least one first frequency layer from the plurality of first frequency layers to measure a first positioning reference signal (e.g., PRS) to obtain RSCP and/or RSRPP.

For another example, the terminal may measure the first positioning reference signal (e.g., PRS) according to a bandwidth aggregation configuration of the first positioning reference signal to obtain RSRP and/or RSRPP.

Through the above embodiment, the terminal may determine the second frequency layer for measuring the first positioning reference signal from the plurality of first frequency layers by itself, and in more possible implementations, the terminal may further determine the second frequency layer according to an instruction of the core network device.

In some embodiments, the core network device may send first indication information to the terminal, where the first indication information may be used to indicate the second frequency layer; the terminal may receive first indication information sent by the core network device, so as to select at least one second frequency layer from the plurality of first frequency layers based on the first indication information.

In some embodiments, the core network device may send a first positioning request message to the terminal, where the first positioning request message may include first indication information; the terminal may receive a first positioning request message sent by the core network device, so as to obtain first indication information included in the first positioning request message.

Optionally, the core network device may send the first positioning request message to the access network device, and the access network device transparently transmits the first positioning request message to the terminal, so that the terminal may receive the first positioning request message sent by the core network device.

The first positioning request message may be an LTE-based positioning protocol (LTE Positioning Protocol, LPP) message, for example, the first positioning request message may be a message (i.e. LPP request location information) for requesting location information in the LPP message, but is not limited thereto, and the first positioning request message may be another type of message, which is not limited thereto by the embodiments of the present disclosure.

In some embodiments, the first indication information may indicate the first frequency layer by any one of: a frequency point number; a reference frequency point; a common reference Point (Point a); a frequency layer index (frequency layer index); a first positioning reference signal resource set identification (PRS resource set ID); a first positioning reference signal resource identifier; frequency layer identification (frequency layer ID).

The reference frequency point may be an NR absolute radio frequency channel number (NR absolute radio frequency channel number, NR-ARFCN), but is not limited thereto, and the reference frequency point may be of another type, which is not limited thereto in the embodiments of the present disclosure.

Alternatively, the first indication information may further indicate the second frequency layer by other manners, which are not limited by the embodiments of the present disclosure.

In some embodiments, the positioning measurement result is a CPP related positioning measurement result, and the terminal may select one first frequency layer from the plurality of first frequency layers as the second frequency layer based on the first indication information.

For example, the terminal may select one second frequency layer for measuring RSCP and/or RSCPD from the plurality of first frequency layers according to an instruction of the core network device.

In some embodiments, the positioning measurement result is a non-time-dependent and/or non-CPP-dependent positioning measurement result, and the terminal may select at least one first frequency layer from the plurality of first frequency layers as the second frequency layer based on the first indication information.

For a description of the non-time-dependent positioning measurement result and the non-CPP-dependent positioning measurement result, reference may be made to the above-mentioned embodiments, and details thereof are omitted herein.

For example, the terminal may select at least one firstfrequency layer for measuring RSRP and/or RSRPP from the plurality of first frequency layers according to an instruction of the core network device.

In step S2103, the terminal measures the first positioning reference signal on the second frequency layer to obtain a positioning measurement result.

In some embodiments, after determining the second frequency layer from the plurality of first frequency layers, the terminal may perform measurement of the first positioning reference signal on the second frequency layer to obtain a positioning measurement result.

In some embodiments, the terminal may measure the first positioning reference signal on a second frequency layer determined from the plurality of first frequency layers to obtain a CPP-related positioning measurement.

For example, the terminal may measure PRS on a second frequency layer determined from the plurality of first frequency layers to obtain RSCP and/or RSCPD.

In some embodiments, the terminal may take each of the plurality of first frequency layers as a second frequency layer, and the terminal may measure the first positioning reference signal on each second frequency layer to obtain a CPP-related positioning measurement result.

For example, if the network configures the terminal with 3 first frequency layers, the terminal may select each of the 3 first frequency layers as a second frequency layer, i.e. determine 3 second frequency layers, and the terminal may measure PRS on each second frequency layer to obtain RSCP and/or RSCPD, i.e. the terminal may obtain 3 positioning measurements (i.e. RSCP and/or RSCPD), where each second frequency layer may correspond to one positioning measurement.

In some embodiments, the terminal may measure the first positioning reference signal on at least one second frequency layer determined from the plurality of first frequency layers to obtain non-time-dependent and/or non-CPP-dependent positioning measurements.

For example, the terminal may measure PRS on at least one second frequency layer determined from the plurality of first frequency layers to obtain RSRP and/or RSRPP.

In some embodiments, the terminal may perform measurement of the first positioning reference signal according to a bandwidth aggregation configuration of the first positioning reference signal to obtain a non-CPP related positioning measurement result.

For example, the terminal may measure PRS according to a bandwidth aggregation configuration of PRS to obtain RSRP and/or RSRPP.

In step S2104, the terminal sends the positioning measurement result to the core network device through the access network device.

In some embodiments, the terminal may send the positioning measurement result to the access network device, and the access network device may send the positioning measurement result to the core network device, so that the core network device may receive the positioning measurement result sent by the terminal.

In the case that the terminal determines the second frequency layer according to the indication of the core network device, the second frequency layer determined by the terminal is indicated by the core network device, so that the core network device already knows that the terminal measures the frequency layer of the first positioning reference signal, and therefore, the terminal only needs to directly send the positioning measurement result to the core network device.

For the case that the terminal selects the second frequency layer by itself, the terminal may send second indication information to the core network device, where the second indication information is used to indicate the second frequency layer, so that the core network device may perform terminal positioning according to the second frequency layer indicated by the second indication information.

In some embodiments, the terminal may send a first positioning response message to the core network device, where the first positioning response message may include second indication information to enable sending of the second indication information.

Optionally, the terminal may send the first positioning response message to the access network device, and the access network device transparently transmits the first positioning response message to the core network device, so that the core network device may receive the first positioning response message sent by the terminal.

The first positioning response message may be an LPP message, for example, the first positioning response message may be a message (i.e. LPP provide location information) for providing location information in the LPP message, but is not limited thereto, and the first positioning response message may also be another type of message, which is not limited thereto by the embodiments of the present disclosure.

In some embodiments, the second indication information may indicate the first frequency layer by any one of: a frequency point number; a reference frequency point; a common reference point; a frequency layer index; a first positioning reference signal resource set identifier; a first positioning reference signal resource identifier; a frequency layer identification; bandwidth aggregate identification.

The reference frequency point may be an NR-ARFCN, but is not limited thereto, and the reference frequency point may be of other types, which is not limited thereto in the embodiments of the present disclosure.

Alternatively, the second indication information may also indicate the second frequency layer by other methods, which are not limited by the embodiments of the present disclosure.

In step S2105, the core network device acquires a positioning measurement result.

In some embodiments, the core network device may receive the positioning measurement result sent by the terminal, so as to obtain the positioning measurement result measured by the terminal on the second frequency layer.

In addition, in the case that the terminal determines the second frequency layer according to the indication of the core network device, the second frequency layer determined by the terminal is indicated by the core network device, so that the core network device already knows the frequency layer of the first positioning reference signal measured by the terminal, and therefore, in this case, the core network device only needs to receive the positioning measurement result measured by the terminal on the second frequency layer.

For the case that the terminal selects the second frequency layer by itself, the terminal may further send second indication information for indicating the second frequency layer to the core network device, so in some embodiments, the core network device may further receive the second indication information sent by the terminal, so as to determine, according to the second frequency layer indicated by the second indication information, the frequency layer used by the terminal to measure the first positioning reference signal.

In some embodiments, the core network device may receive a first positioning response message sent by the terminal, where the first positioning message may include second indication information, so that the core network device may obtain the second indication information. The description of the first positioning response message and the second indication information may be referred to the above embodiments, and will not be repeated here.

It should be noted that, the frequency layer in the embodiments of the present disclosure may also be a partial Bandwidth (BWP) or a carrier (carrier), but is not limited thereto, and the embodiments of the present disclosure are not limited thereto.

It should be noted that, in the embodiment of the present disclosure, the first network element of the core network device may interact with the terminal. Wherein the first network element may be an LMF.

For example, step S2102 may be implemented as an independent embodiment, step S2104 may be implemented as an independent embodiment, step S2101 and step S2102 may be implemented as independent embodiments, step S2102 and step S2103 may be implemented as independent embodiments, and step S2103 and step S2104 may be implemented as independent embodiments, but are not limited thereto.

In some embodiments, steps S2101, S2102, S2103 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

In some embodiments, step S2104 is optional, and may be omitted or replaced in different embodiments.

In some embodiments, the access network device may monitor the second positioning reference signal in a plurality of third frequency layers to obtain positioning measurements to the terminal by measuring the second positioning reference signal.

Wherein the second positioning reference signal may be a sounding reference signal (Sounding Reference Signal, SRS). Alternatively, the second positioning reference signal may be sent by the terminal to the access network device. For example, the terminal may transmit SRS to the access network device on a plurality of third frequency layers.

In step S2202, the access network device determines at least one fourth frequency layer among the plurality of third frequency layers for transmitting the second positioning reference signal.

It should be noted that the access network device may have the capability to receive the second positioning reference signal on a plurality of third frequency layers, but the fourth frequency layer of the second positioning reference signal used for measurement may be different when different types of positioning measurements are obtained.

In some embodiments, the access network device may determine at least one fourth frequency layer among the plurality of third frequency layers. Alternatively, the access network device may have the capability to actively select the fourth frequency layer, or the access network device may make the determination of the fourth frequency layer according to an instruction of the core network device.

In some embodiments, the access network device is provided with the capability to actively select the fourth frequency layer, e.g. the access network device may determine at least one fourth frequency layer from the plurality of third frequency layers depending on the type of positioning measurement to be obtained.

In some embodiments, the positioning measurement is a CPP-related positioning measurement, and the terminal may select one third frequency layer from the plurality of third frequency layers as the fourth frequency layer.

The CPP-related positioning measurement result represents a measurement result obtained by measuring the carrier phase of the reference signal by the terminal. Alternatively, the CPP-related positioning measurements may include RSCP and/or RSCPD, but are not limited thereto, and the CPP-related positioning measurements may also include other types of positioning measurements, and the embodiments of the present disclosure are not limited.

For example, the access network device may select a fourth frequency layer from the plurality of third frequency layers to measure a second positioning reference signal (e.g., SRS) to obtain RSCP and/or RSCPD.

Optionally, the access network device may select one third frequency layer from the plurality of third frequency layers as a fourth frequency layer based on the second default condition, where the fourth frequency layer may be used to measure the CPP related positioning measurement result.

For example, the access network device may determine default frequency layer from the plurality of third frequency layers based on the second default condition, such that the default frequency layer may be used as a fourth frequency layer for measuring CPP-related positioning measurements.

Optionally, the second default condition may include any one of:

That is, default frequency layer may be a frequency layer corresponding to the first frequency (frequency) in the frequency list; alternatively, default frequency layer can be the lowest frequency layer among the plurality of third frequency layers; alternatively, default frequency layer can be the largest bandwidth frequency layer among the plurality of third frequency layers.

In some embodiments, the positioning measurement result is a CPP related positioning measurement result, and the terminal may further determine each of the third frequency layers as a fourth frequency layer, so that measurement of the second positioning reference signal may be performed on each fourth frequency layer.

In some embodiments, the positioning measurement is a non-time dependent positioning measurement, and the access network device may select at least one frequency layer from the plurality of third frequency layers as the fourth frequency layer.

The time-related positioning measurement result may include at least one of uplink relative arrival time (uplink relative time of arrival, UL RTOA), RSTD, base station receive-transmit time difference (gNB receive-transport time difference, gNB Rx-Tx time difference), TOA, but is not limited thereto, and the time-related positioning measurement result may also include other types of positioning measurement results. It should be noted that other positioning measurements than those listed above are non-time dependent positioning measurements.

For example, the access network device may select at least one fourth frequency layer from the plurality of third frequency layers to measure a second positioning reference signal (e.g., SRS) to obtain RSCP and/or RSRPP.

In some embodiments, the positioning measurement is a non-CPP related positioning measurement, the access network device may select at least one frequency layer from the plurality of third frequency layers as the fourth frequency layer, or the access network device may determine the fourth frequency layer according to a bandwidth aggregation configuration of the second positioning reference signal.

Alternatively, the terminal may determine by what manner to determine the fourth frequency layer to obtain the non-CPP related location measurement result according to the protocol convention, or the terminal may freely select by what manner to determine the fourth frequency layer to obtain the non-CPP related location measurement result based on the implementation.

In some embodiments, the positioning measurement result is a CPP related positioning measurement result, and the access network device may select, based on the third indication information, one frequency layer from the plurality of third frequency layers as the fourth frequency layer.

For example, the access network device may select one fourth frequency layer for measuring RSCP and/or RSCPD from the plurality of third frequency layers according to an instruction of the core network device.

In some embodiments, the positioning measurement is a non-time-dependent and/or non-CPP-dependent positioning measurement, and the access network device may select at least one third frequency layer from the plurality of third frequency layers as the fourth frequency layer based on the third indication information.

For example, the access network device may select at least one fourth frequency layer for measuring at least one of RSRP, RSRPP, and UL AOA from the plurality of third frequency layers according to an indication of the core network device.

In some embodiments, the access network device may use each of the plurality of third frequency layers as a fourth frequency layer, and the access network device may measure the second positioning reference signal on each fourth frequency layer to obtain a CPP-related positioning measurement result.

For example, if the network configures the access network device with 3 third frequency layers, the access network device may select each third frequency layer of the 3 third frequency layers as a fourth frequency layer, i.e. determine 3 fourth frequency layers, and the access network device may measure SRS on each fourth frequency layer to obtain RSCP and/or RSCPD, i.e. the access network device may obtain 3 positioning measurement results (i.e. RSCP and/or RSCPD), where each fourth frequency layer may correspond to one positioning measurement result.

It should be noted that, in the case that the access network device determines the fourth frequency layer according to the indication of the core network device, the fourth frequency layer determined by the access network device is indicated by the core network device, so that the core network device already knows that the access network device measures the frequency layer of the second positioning reference signal, and therefore, the access network device only needs to directly send the positioning measurement result measured on the fourth frequency layer to the core network device.

For the case that the access network device selects the fourth frequency layer by itself, the access network device may send fourth indication information to the core network device, where the fourth indication information is used to indicate the fourth frequency layer, so that the core network device may perform terminal positioning according to the fourth frequency layer indicated by the fourth indication information.

In some embodiments, the access network device may send a second positioning response message to the core network device, where the second positioning response message may include fourth indication information to enable sending of the fourth indication information.

The second positioning response message may be an NRPPa message, for example, the second positioning response message may be a measurement report message (i.e. NRPPa measurement report) or a measurement update message (i.e. NRPPa measurement update) in the NRPPa message, but is not limited thereto, and the second positioning response message may also be other types of messages, which are not limited thereto by the embodiments of the present disclosure.

In some embodiments, the core network device may receive the positioning measurement result sent by the access network device, so as to obtain a positioning measurement result measured by the access network device on the fourth frequency layer.

It should be noted that, in the case that the access network device determines the fourth frequency layer according to the indication of the core network device, the second frequency layer determined by the access network device is indicated by the core network device, so that the core network device already knows the frequency layer of the access network device for measuring the second positioning reference signal, and therefore, in this case, the core network device only needs to receive the positioning measurement result measured by the access network device on the fourth frequency layer.

For the case that the access network device selects the fourth frequency layer by itself, the access network device may further send fourth indication information for indicating the fourth frequency layer to the core network device, so in some embodiments, the core network device may further receive the fourth indication information sent by the access network device, so as to determine, according to the fourth frequency layer indicated by the fourth indication information, the frequency layer used by the access network device to measure the second positioning reference signal.

In some embodiments, the core network device may receive a second positioning response message sent by the access network device, where the second positioning message may include the fourth indication information, so that the core network device may obtain the fourth indication information. For the second response message and the fourth indication message, reference may be made to the above embodiments, and details thereof are not repeated here.
