[0003] At present, the reference signal used for carrier phase positioning technology is a sounding reference signal (SRS) or a positioning reference signal (PRS). However, the performance that can be achieved by the reference signal currently used in carrier phase positioning technology may not meet the positioning requirements of some scenarios. Summary of the invention

[0004] The embodiments of the present application provide a signal configuration method, device and system for configuring a reference signal to improve positioning effect.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

The following is an example of a terminal device executing the method, and the method includes: the terminal device receives first configuration information, and configures a reference signal according to the first configuration information. The reference signal corresponds to at least two subbands on the same time domain resource, and adjacent subbands of the at least two subbands are separated by at least one frequency domain unit in the frequency domain.

[0007] Based on the signal configuration method provided in the embodiment of the present application, reference signals occupying different frequency domain resources on the same time domain resource can be configured, thereby improving positioning accuracy, while also reducing the load and improving the overall signal interference noise ratio (SINR).

[0008] In a second aspect, a signal configuration method is provided, which can be executed by an access network device or by a module (such as a processor, a chip, or a chip system, etc.) applied to the access network device. The following is an example of an access network device executing the method, and the method includes: the access network device generates first configuration information and sends the first configuration information. The first configuration information is used to correspond to at least two subbands on the same time domain resource, and adjacent subbands in at least two subbands are separated by at least one frequency domain unit in the frequency domain.

[0010] Based on the signal configuration method provided in the embodiment of the present application, a first frequency domain resource can be configured through the first indication information, and the position of the subband of the reference signal in the first frequency domain resource can be configured through the corresponding second indication information, thereby realizing the configuration of the reference signal. Among them, the design of configuring the position of the subband of the reference signal in the first frequency domain resource through the second indication information can save the resource overhead of separately configuring the frequency domain position and bandwidth of each subband for the reference signal of multiple subbands, and realize that the multiple subband reference signals occupy different frequency domain resources on the same time domain resource.

[0011] In combination with the above-mentioned first aspect or second aspect, in a possible design, the first configuration information includes third indication information; the third indication information is used to indicate the interval between the frequency domain position of other subbands except the first subband in at least two subbands and the frequency domain position of the first subband.

[0012] Based on the signal configuration method provided in the embodiment of the present application, the reference signal of multiple subbands can be configured by configuring the offset of one subband and other subbands compared with the subband.

[0013] In combination with the above-mentioned first aspect or second aspect, in a possible design, the first configuration information includes fourth indication information; the fourth indication information is used to indicate identification information of signal sequences corresponding to at least two subbands respectively; and the identification information of the signal sequence is used to generate a signal sequence.

[0014] Based on the signal configuration method provided in the embodiment of the present application, different signal sequences can be configured for different subbands through different fourth indication information, so that different subbands of the reference signal can generate different signal sequences, thereby reducing the overall peak to average power ratio (PAPR) of the signal.

[0015] In combination with the above-mentioned first aspect or second aspect, in a possible design, the first configuration information includes at least one of fifth indication information and sixth indication information; wherein the fifth indication information is used to indicate the comb structure size corresponding to at least two subbands respectively; and the sixth indication information is used to indicate the reference signal corresponding to the transmission power of at least two subbands respectively.

[0048] In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction to the related technologies of the present application is first given as follows.

[0049] 1. Carrier phase positioning technology

[0050] Carrier phase positioning technology is one of the main methods of high-precision positioning at present. It measures the distance with integer ambiguity by measuring the carrier phase change of the reference signal from the transmitter to the receiver. Therefore, when the carrier phase integer ambiguity can be correctly solved, the carrier phase ranging accuracy can theoretically reach the centimeter to millimeter level, thus obtaining a high-precision positioning result.

[0051] Figure 1 Schematic diagram of the distance measurement of carrier phase positioning technology. Where d is the distance between the receiving end and the transmitting end; is the carrier phase measurement value; N represents the integer ambiguity, which is an integer, representing that N carrier cycles have passed. λ is the carrier wavelength, and the distance d is related to the carrier phase The following equation is satisfied:

[0052]

[0053] At present, the reference signal used by the carrier phase positioning technology is the existing SRS signal or PRS signal. Among them, the SRS signal is an uplink reference signal, and the PRS signal is a downlink reference signal. If the SRS signal is used, the terminal device can configure and send the SRS signal according to the configuration information sent by the network side for configuring the SRS signal, and the network side can measure the received SRS signal to locate the terminal device. If the PRS signal is used, the network side can send the PRS signal, and the terminal device can measure the received PRS signal to locate the device on the network side that sends the PRS signal.

[0054] According to the existing configuration method, the existing SRS signal or PRS signal occupies all resources corresponding to the configured bandwidth on the same symbol. Figure 2 As shown, assuming that the network side configures symbol 1 and a bandwidth of 100 MHz for the SRS signal, the SRS signal occupies all resources corresponding to the 100 MHz on symbol 1.

[0093] The following will be combined Figures 1 to 6 ,by Figure 5 Taking the interaction between the access network device 20 and the terminal device 30 as an example, the signal configuration method provided in the embodiment of the present application is described in detail.

[0094] It should be noted that the message names between network elements or the names of parameters in the messages in the following embodiments of the present application are merely examples, and other names may be used in specific implementations, and the embodiments of the present application do not impose any specific limitations on this.

[0095] like Figure 7 As shown, it is a process of a signal configuration method provided in an embodiment of the present application. Figure 7 The method is illustrated by taking the terminal device and the access network device as the execution subject of the process as an example, but the present application does not limit the execution subject of the process. Figure 7 The terminal device in the term "device" may also be a module applied to the terminal device, such as a chip, a chip system, or a processor, or a logical node, a logical module, or software that can implement all or part of the functions of the terminal device. Figure 7 The access network device in the signal configuration method may also be a module applied to the access network device, such as a chip, a chip system, or a processor, or a logical node, a logical module, or software that can realize all or part of the functions of the access network device. The signal configuration method includes steps S701-S702:

[0096] S701. The terminal device obtains first configuration information.

[0097] In S701, after the access network device generates first configuration information, it sends the first configuration information to the terminal device. The first configuration information is used to configure a reference signal.

[0098] Optionally, the access network device sending the first configuration information to the terminal device may be triggered by a request message sent by other network elements to the access network device requesting configuration of a reference signal for the terminal device.

[0099] For example, if the LMF network element wants to locate a certain terminal device, the LMF network element can send a request message to the access network device serving the terminal device, and the request message requests to configure a reference signal for the terminal device. After receiving the request message, the access network device generates first configuration information and sends it to the terminal device.

[0100] After receiving the first configuration information, the terminal device executes S702.

[0101] S702. The terminal device configures a reference signal according to the first configuration information; the reference signal corresponds to at least two subbands at the same time domain position, and adjacent subbands in the at least two subbands are separated by at least one frequency domain unit in the frequency domain.

[0102] The first configuration information may include information for configuring time domain resources of the reference signal and information for configuring frequency domain resources of the reference signal.

[0103] Optionally, the information for configuring the time domain resources of the reference signal may configure the starting time domain position of the reference signal and the length of the continuous time-frequency resources occupied. In a possible implementation, the information for configuring the time domain resources of the reference signal may configure the time domain unit in which the starting time domain position of the reference signal is located and the number of continuous time domain units occupied by the reference signal.

[0104] The time domain unit may be a time slot, a symbol or other time domain units, and the embodiments of the present application do not impose any specific restrictions on this.

[0105] Exemplarily, assuming that the symbol (which may be referred to as the starting symbol) at which the starting time domain position of the reference signal configured by the first configuration information is located is symbol 1, and the configured reference signal occupies 2 consecutive symbols in the time domain, then the reference signal configured based on the first configuration information can occupy a section of continuous time domain resources corresponding to symbol 1 to symbol 2 in the time domain.

[0106] In the embodiment of the present application, the reference signal configured by the first configuration information may correspond to at least two subbands on the same time domain resource, and in the at least two subbands, adjacent subbands are separated by at least one frequency domain unit in the frequency domain.

[0107] The same time domain resource may include one or more time domain units.

[0108] In the embodiment of the present application, a subband can be understood as a continuous frequency domain resource. A subband can occupy one or more frequency domain units.

[0109] Optionally, the frequency domain unit may be a resource block (RB), a resource element (RE) or other resource units occupied in the frequency domain, and the embodiments of the present application do not impose any specific restrictions on this.

[0110] Optionally, at least two subbands of the reference signal may be located in the same partial bandwidth (BWP).

[0111] Optionally, the first configuration information may configure multiple subbands of the reference signal by configuring a frequency domain resource and corresponding multiple sets of configuration parameters.

[0112] The specific implementation of configuring the subband of the reference signal by the first configuration information is introduced below.

[0113] Implementation method 1: The first configuration information includes first indication information, the first indication information is used to indicate the first frequency domain resource. The first configuration information also includes second indication information, the second indication information is used to indicate the positions of at least two subbands in the first frequency domain resource.

[0114] For the first indication information indicating the first frequency domain resource, optionally, the first indication information may indicate the starting frequency domain position of the first frequency domain resource, and the resource size of the first frequency domain resource. In one possible implementation, the first indication information may indicate the frequency domain unit where the starting time domain position of the first frequency domain resource is located, and the number of frequency domain units included in the first frequency domain resource.

[0115] For example, assuming that the frequency domain unit is an RB, the first indication information may indicate the BWP where the first frequency domain resource is located, and the number of resource blocks (RBs) between the starting frequency domain position of the first frequency domain resource and the starting frequency domain position of the BWP, so that the terminal device can determine the RB where the starting frequency domain position of the first frequency domain resource is located based on the first indication information. The first indication information may also indicate the number of RBs included in the first frequency domain resource, so that the terminal device can determine the first frequency domain resource in combination with the starting frequency domain position of the first frequency domain resource. For example, assuming that the first indication information indicates that the starting time domain position of the first frequency domain resource is RB0, and the first frequency domain resource includes 272 RBs, the terminal device can determine that the first frequency domain resource is a continuous frequency domain resource from RB0 to RB271.

[0116] Among them, optionally, the first indication information can directly indicate the number of frequency domain units included in the first frequency domain resource. For example, the first indication information is a field, and the value of the field (such as the decimal value converted from the bit value of the field) is the number of frequency domain units. Alternatively, the first indication information can also indirectly indicate the number of frequency domain units included in the first frequency domain resource. The following introduces an exemplary method of indirectly indicating the number of frequency domain units included in the first frequency domain resource.

[0117] In this manner, the terminal device and the access network device pre-agree / pre-define / pre-configure a mapping relationship between the value of a certain parameter included in the first indication information and the number of frequency domain units, and the access network device can indicate the number of frequency domain units included in the first frequency domain resource through the value of the parameter in the first indication information. After receiving the first indication information, the terminal device determines the number of frequency domain units corresponding to the value of the parameter as the number of frequency domain units included in the first frequency domain resource.

[0118] Exemplarily, it is assumed that the first indication information includes a freqHopping parameter, and the freqHopping parameter includes C SRS Parameters, pre-configured mapping relationship, C SRS The value of the parameter is related to m SRS,0 The values ​​of have a corresponding relationship, where m SRS,0 The value of represents the number of frequency domain units included in the first frequency domain resource. Assume that in the preconfigured mapping relationship, C SRS = 0, the corresponding m SRS,0 =4, C SRS =9, the corresponding m SRS,0 =32, then if C in the first indication information SRS =0, the terminal device may determine that the first frequency domain resource includes 4 frequency domain units. If C in the first indication information SRS =9, the terminal device can determine that the first frequency domain resources include 32 frequency domain units.

[0119] The above describes how the first indication information indicates the first frequency domain resource. As for how the second indication information indicates the positions of at least two subbands in the first frequency domain resource, in a possible implementation, if the first frequency domain resource is divided into several continuous frequency domain resources, the second indication information can indicate which frequency domain resource the at least two subbands corresponding to the reference signal are, thereby indicating the position of each subband in the first frequency domain resource. The following describes the specific implementation of dividing the first frequency domain resource into several frequency domain resources.

[0120] Optionally, the first configuration information may include information indicating the number of resource segments into which the first frequency domain resources are divided.

[0121] Among them, the access network device can directly indicate the number of resource segments into which the first frequency domain resource is divided. For example, the indication information is a field, and the value of the field is the number of resource segments. Alternatively, the indication information can also indirectly indicate the number of resource segments into which the first frequency domain resource is divided. For example, the terminal device and the access network device can pre-agree / pre-define / pre-configure the mapping relationship between the value of a parameter included in the first configuration information and the number of resource segments, and the access network device can indicate how many segments the first frequency domain resource is divided into through the value of the parameter in the first configuration information.

[0122] Optionally, the size of each segment of the first frequency domain resource may be the same or different.

[0123] Optionally, the first configuration information may include information indicating the number of frequency domain units included in each segment of the first frequency domain resources.

[0124] The information indicating the number of frequency domain units included in each segment of the first frequency domain resources may be carried in the first indication information or the second indication information, or may be information independent of the first indication information or the second indication information.

[0125] Among them, the information indicating the number of frequency domain units included in each segment of the first frequency domain resource can directly indicate the number of frequency domain units included in each segment of the first frequency domain resource. For example, the indication information is a field, and the value of the field is the number of frequency domain units included in each segment. Alternatively, the indication information can also indirectly indicate the number of frequency domain units included in each segment of the first frequency domain resource. For example, the terminal device and the access network device can pre-agree / pre-define / pre-configure the mapping relationship between the value of a parameter included in the first configuration information and the number of frequency domain units included in each segment of the first frequency domain resource. The access network device can indicate the number of frequency domain units included in each segment of the first frequency domain resource through the value of the parameter in the first configuration information.

[0126] Further, based on each segment of frequency domain resources into which the first frequency domain resources are divided, the second indication information may indicate the sequence number of one or more segments of frequency domain resources, and the terminal device may determine which segment of frequency domain resources the at least two subbands corresponding to the reference signal are based on the sequence number indicated by the second indication information. For example, if the second indication information indicates 1, 4, it means that one subband is the first segment of frequency domain resources in the first frequency domain resources, and the other subband is the fourth segment of frequency domain resources in the first frequency domain resources. Among them, the sequence number of each segment of frequency domain resources into which the first frequency domain resources are divided may be determined according to the position order of each segment of frequency domain resources in the frequency domain (for example, the order of frequency domain positions from high to low or from low to high).

[0127] The following introduces a specific example to introduce the specific implementation of the subband of the reference signal indicated by the first indication information and the second indication information.

[0128] Exemplarily, it is assumed that the first configuration information includes a freqHopping parameter and a freqDomainPosition parameter. The freqHopping parameter may include C SRS Parameters and B SRS Parameters. It is assumed that the frequency domain unit is the frequency domain resource occupied by the RB. The terminal device and the access network device are pre-configured with the mapping relationship shown in Table 1.

[0129] Table 1

[0130]

[0131] In Table 1, C SRS The corresponding m SRS,0 The value of is the number of frequency domain units occupied by the first frequency domain resource. SRS = i, the corresponding N i The value used to combine N1, N2, ..., N i-1 The value of determines how many segments the first frequency domain resource is divided into, and the corresponding m SRS,i The value of is the number of frequency domain units occupied by a segment of the first frequency domain resource. The value of the freqDomainPosition parameter is used to indicate the frequency domain resource corresponding to which segment of the first frequency domain resource each subband occupies.

[0132] For example, assuming that C SRS =9, B SRS =2, freqDomainPosition = 1, 4. As shown in Table 1, when C SRS =9, corresponding to C SRS =9 in the row, m SRS,0 =32, indicating that the first frequency domain resource occupies 32 frequency domain units. SRS =2, m SRS,2 =8, indicating that each segment of the first frequency domain resource occupies 8 frequency domain units, N2=2, combined with N1=2, we get 2×2=4, indicating that the first frequency domain resource can be divided into 4 segments. freqDomainPosition=1,4, indicating that the reference signal can correspond to two subbands, one of which occupies the frequency domain resource corresponding to the first segment of the first frequency domain resource, and the other subband occupies the frequency domain resource corresponding to the fourth segment of the first frequency domain resource. Figure 8 is a schematic diagram of the distribution of the reference signal corresponding to this example, such as Figure 8 As shown, the two subbands of the reference signal are respectively distributed at two ends of the first frequency domain resource.

[0133] Similarly, if C SRS =9, B SRS =3, as shown in Table 1, corresponding to C SRS=9, B SRS =3, m SRS,3 =4, indicating that each segment of the first frequency domain resource occupies 4 frequency domain units, N3=2, combined with N1=2, N2=2, we get 2×2×2=8, indicating that the first frequency domain resource can be divided into 8 segments. If freqDomainPosition=1, 5, 8, it means that the reference signal can correspond to three sub-bands, the first sub-band occupies the frequency domain resource corresponding to the first segment of the first frequency domain resource, the second sub-band occupies the frequency domain resource corresponding to the fifth segment of the first frequency domain resource, and the third sub-band occupies the frequency domain resource corresponding to the eighth segment of the first frequency domain resource. Fig. 9 is a schematic diagram of the distribution of the reference signal corresponding to this example, such as Fig. 9 As shown, the three subbands of the reference signal are respectively distributed at both ends and in the middle of the first frequency domain resource.

[0134] In particular, if freqDomainPosition=0, it means that the reference signal corresponds to one subband, and this subband occupies all the first frequency domain resources.

[0135] For example, the complete content of Table 1 can refer to the content shown in Table 6.4.1.4.3-1 (Table 6.4.1.4.3-1): SRS bandwidth configuration table (SRS bandwidth configuration) in the 38.211 protocol. Of course, the parameters in Table 1 can also be other values, and the embodiment of the present application does not specifically limit the content of Table 1.

[0136] Exemplarily, the freqDomainPosition parameter may be carried in the first configuration information in the following manner.

[0137]

[0138] Among them, freqDomainPosition1 can take any value in (0, ..., 67), for example, it can take 1, which is used to indicate that subband 1 occupies the frequency domain resources corresponding to the first segment in the first frequency domain resources. freqDomainPosition2 can take any value in (0, ..., 67), for example, it can take 4, indicating that subband 2 occupies the frequency domain resources corresponding to the fourth segment in the first frequency domain resources.

[0139] Exemplarily, the freqHopping parameter may be carried in the first configuration information in the following manner.

[0140]

[0141] Among them, C SRS It can take any value in (0, ..., 63), B SRSCan take any value in (0, ..., 3), C SRS and B SRS The specific implementation of indicating the first frequency domain resource can be referred to the above introduction and will not be elaborated here.

[0142] In the above implementation method 1, the access network device can configure a first frequency domain resource through the first indication information, and configure the position of the subband of the reference signal in the first frequency domain resource through the corresponding multiple sets of parameters (i.e., the second indication information), thereby configuring the reference signal. Among them, the design of configuring the position of the subband of the reference signal in the first frequency domain resource through the second indication information can save the resource overhead of separately configuring the frequency domain position and bandwidth of each subband for the reference signal of multiple subbands, and realize that the multiple subband reference signals occupy different frequency domain resources (such as occupying different RBs) on the same time domain resource (such as the same symbol).

[0143] Implementation method 2: The first configuration information includes third indication information; the third indication information is used to indicate the interval between the frequency domain starting position of other subbands except the first subband in at least two subbands and the frequency domain starting position of the first subband.

[0144] In this implementation manner, the first configuration information may include information for configuring frequency domain resources occupied by the first sub-band.

[0145] Optionally, the first configuration information may indicate the starting frequency domain position of the first subband, and the size of the frequency domain resources occupied by the first subband. In one possible implementation, the first configuration information may indicate the frequency domain unit where the starting time domain position of the first subband is located, and the number of frequency domain units occupied by the first subband. For details, please refer to the above introduction of the first indication information indicating the first frequency domain resource in the first implementation method, which will not be expanded here.

[0146] Optionally, the first configuration information may directly indicate the number of frequency domain units included in the first subband, or may indicate it indirectly. For details, reference may be made to the above introduction of the first indication information indicating the first frequency domain resource in implementation manner 1, which will not be elaborated here.

[0147] Further, the third indication information may indicate the number of frequency domain units (which may also be understood as an offset in the frequency domain) between the frequency domain starting position of other subbands except the first subband and the frequency domain starting position of the first subband. For example, assuming that the frequency domain starting position of the first subband of the reference signal is located at RB0, the third indication information may indicate that the frequency domain starting position of another subband of the reference signal differs from the frequency domain starting position of the first subband by 36 RBs, then the terminal device may determine that the frequency domain starting position of the subband is located at RB37.

[0148] Exemplarily, the third indication information may be a freqDomain offset parameter in the first configuration information. For example, a value of the freqDomain offset parameter is 36, indicating that a frequency domain starting position of another subband differs from a frequency domain starting position of the first subband by 36 RBs.

[0149] In the embodiment of the present application, the third indication information corresponds to the indicated subband in one-to-one correspondence. That is, one third indication information is used to indicate the interval between the frequency domain starting position of a subband and the frequency domain starting position of the first subband. If the reference signal corresponds to at least three subbands (at least two subbands in addition to the first subband), the first configuration information also includes at least two third indication information accordingly. Exemplarily, if the reference signal corresponds to 3 subbands, two freqDomainoffset parameters can be configured to indicate the offset between the starting frequency domain position of the remaining two subbands in the three subbands and the starting frequency domain position of the first subband.

[0150] Exemplarily, the freqDomainoffset parameter may be carried in the first configuration information in the following manner:

[0151] freqDomainoffset SEQUENCE{

[0152] offset1-r19 INTEGER(0..272),

[0153] offset2-r19 INTEGER(0..272),

[0154] Wherein, offset1-r19 can take any value in (0, ..., 272), which is used to indicate the offset between the frequency domain starting position of subband 1 and the frequency domain starting position of the first subband. Offset2-r19 can take any value in (0, ..., 272), which is used to indicate the offset between the frequency domain starting position of subband 2 and the frequency domain starting position of the first subband.

[0155] Optionally, in this implementation, the size of the frequency domain resources occupied by the other subbands of the reference signal and the first subband may be the same. That is, the information included in the first configuration information for configuring the size of the frequency domain resources occupied by the first subband may also be used to configure the size of the frequency domain resources occupied by other subbands. Alternatively, the size of the frequency domain resources occupied by the other subbands of the reference signal and the first subband may also be different. In this case, the first configuration information may also include information for configuring the size of the frequency domain resources occupied by other subbands.

[0156] In the above implementation method 2, the access network device can configure the reference signal of multiple subbands by configuring a subband and the offset of other subbands compared to the subband. Among them, the design of configuring the frequency domain position of other subbands by the offset indicated by the third indication information can save the resource overhead of configuring the frequency domain position and bandwidth of each subband separately for the reference signal of multiple subbands, and realize that the reference signals of multiple subbands occupy different frequency domain resources (such as occupying different RBs) on the same time domain resources (such as the same symbol).

[0157] The above describes a possible implementation method of configuring the frequency domain resources occupied by at least two sub-bands corresponding to the reference signal by the first configuration information. As described above, the signal configuration method provided in the embodiment of the present application can realize that the configured reference signal occupies different frequency domain resources on the same time-frequency resource. Fig.10 As shown, if the SRS corresponds to two subbands, and these two subbands only occupy the frequency domain resources at both ends of the entire bandwidth, and the middle part is not occupied, then this SRS can be called a dual-subband reference signal (DS-RS) (it can also be called other names, which are not limited by the embodiments of the present application). After verification by simulation results, when a reference signal such as DS-RS is designed for positioning, it can achieve higher-precision carrier phase positioning, and it can also reduce the load and improve the overall SINR of the signal. Therefore, based on the signal configuration method provided in the embodiment of the present application, it is possible to configure DS-RS, thereby achieving higher-precision carrier phase positioning, reducing the load, and improving the overall SINR of the signal.

[0158] Optionally, the first configuration information may further configure signal sequences corresponding to at least two subbands. In a possible implementation, the first configuration information may further include fourth indication information, wherein the fourth indication information is used to indicate identification information (e.g., an ID of the signal sequence) of the signal sequences corresponding to at least two subbands, and the identification information of the signal sequence is used to generate the signal sequence.

[0159] Optionally, the fourth indication information and the subband corresponding to the reference signal may correspond one to one, and the first configuration information may indicate the signal sequence corresponding to each subband of the reference signal through multiple fourth indication information. Alternatively, one fourth indication information may correspond to multiple subbands, and be used to indicate the signal sequences corresponding to the multiple subbands.

[0160] Exemplarily, the fourth indication information may be a sequenceId parameter in the first configuration information.

[0161] Exemplarily, the sequenceId parameter may be carried in the first configuration information in the following manner:

[0162] sequenceId-r19 SEQUENCE{

[0163] sequenceId1 INTEGER(0..65535),

[0164] sequenceId2 INTEGER(0..65535),

[0165] Wherein, sequenceId1 can take any value in (0, ..., 65535), which is used to indicate the ID of the signal sequence of subband 1. sequenceId2 can take any value in (0, ..., 65535), which is used to indicate the ID of the signal sequence of subband 2.

[0166] Based on this solution, different signal sequences can be configured for different subbands through different fourth indication information, thereby reducing the overall peak-to-average power ratio of the signal.

[0167] Optionally, the first configuration information may further include fifth indication information. The fifth indication information is used to indicate the comb size (combsize) corresponding to at least two subbands of the reference signal. Optionally, the fifth indication information and the subband may correspond one to one, and the first configuration information may indicate the combsize corresponding to each subband of the reference signal through multiple fifth indication information. Alternatively, one fifth indication information may correspond to multiple subbands, and is used to indicate the combsize corresponding to multiple subbands.

[0168] Exemplarily, the fifth indication information may be a combsize parameter in the first configuration information.

[0169] Optionally, the first configuration information may further include sixth indication information, and the sixth indication information is used to indicate the reference signal corresponding to the transmit power of at least two subbands of the reference signal. Optionally, the sixth indication information and the subband may correspond one to one, and the first configuration information may indicate the reference signal corresponding to the transmit power of each subband of the reference signal through multiple sixth indication information. Alternatively, one sixth indication information may also correspond to multiple subbands, and is used to indicate the reference signal corresponding to the transmit power of multiple subbands.

[0170] Exemplarily, the sixth indication information may be a spatialRelationInfoPos parameter in the first configuration information.

[0171] Optionally, the first configuration information may also include other information for configuring a reference signal, which is not limited in this embodiment of the present application.

[0172] Optionally, the reference signal configured by the first configuration information can be used in a carrier phase positioning scenario. In this scenario, after the terminal device configures the reference signal according to the first configuration information, it can send the reference signal to the access network device involved in the positioning. Correspondingly, the access network device can measure the received reference signal and report the measurement result to the core network element, which can perform corresponding calculations based on the measurement result to obtain the positioning result.

[0173] For example, if the signal configuration method provided in the present application is applied to a carrier phase positioning scenario, a possible specific process of carrier phase positioning can be as follows: Fig.11 As shown, the following steps are included:

[0174] S1101. The LMF network element sends a positioning information request message (NRPPaPositioninginformationrequest) to the UE's serving base station (ServinggNB) through the NR positioning protocol (NRpositioningprotocolA, NRPPa), requesting the configuration of SRS for the UE.

[0175] S1102, ServinggNB determines the available DS-RS resources (referring to the uplink resources that can be used for UE to send DS-RS), and sends the first configuration information to the UE, where the first configuration information is used to configure DS-RS. For details, please refer to the above introduction to S701 and S702, which will not be expanded here.

[0176] S1103. ServinggNB reports the first configuration information to the LMF network element through the NRPPa positioning information response message (NRPPaPositioninginformationresponse).

[0177] S1104. The LMF network element sends an NRPPa measurement request message (NRPPameasurementrequest) including the first configuration information to the neighboring base station (neighbourgNB) participating in the positioning through NRPPa, requesting to measure the DS-RS.

[0178] S1105. The UE sends DS-RS to each gNB (Serving gNB and neighbor NB) according to the first configuration information.

[0179] It should be noted that Fig.11 The timing sequence between S1103 , S1104 and S1105 shown is only an exemplary possible timing sequence, and the embodiment of the present application does not limit the timing sequence between S1103 , S1104 and S1105 .

[0180] S1106. Each gNB (Serving gNB and neighbor NB) measures the DS-RS sent by the UE to obtain the carrier phase measurement result.

[0181] S1107. Each gNB (Serving gNB and neighbor NB) reports the multi-frequency carrier phase measurement value to the LMF network element through the NRPPa measurement response message (NRPPa measurement response) based on the carrier phase measurement result.

[0182] S1108. The LMF network element performs carrier phase calculation according to the carrier phase measurement value to obtain a UE positioning result.
