[0033] Please refer to Figure 1, which shows a schematic diagram of the structure of a wireless communication system provided by an embodiment of the present disclosure. As shown in Figure 1, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: a plurality of UEs 11, a plurality of access devices 12, and a plurality of core network devices 13.

[0034] UE 11 may refer to a device that provides voice and / or data connectivity to a user. UE 11 may communicate with one or more core networks via a Radio Access Network (RAN).

Alternatively, the UE 11 may also be a roadside device, for example, a street lamp, a traffic light, or other roadside device with a wireless communication function.

[0035] The access device 12 may be a network-side device in a wireless communication system. The wireless communication system may be a fourth generation mobile communication technology (4G) system, also known as a long term evolution (LTE) system; or, the wireless communication system may be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a next generation system of the 5G system. The access network in the 5G system may be referred to as NG-RAN (New Generation-Radio Access Network). Alternatively, an MTC system.

[0036] Among them, the access device 12 can be an evolved access device (eNB) adopted in a 4G system. Alternatively, the access device 12 can also be an access device (gNB) that adopts a centralized distributed architecture in a 5G system. When the access device 12 adopts a centralized distributed architecture, it usually includes a centralized unit (CU) and at least two distributed units (DU). The centralized unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link layer control protocol (RLC) layer, and a media access control (MAC) layer; the distributed unit is provided with a physical (PHY) layer protocol stack. The embodiment of the present disclosure does not limit the specific implementation method of the access device 12.

[0037] A wireless connection can be established between the access device 12 and the UE 11 via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

[0038] Several access network devices 12 are respectively connected to a core network device 13. The core network device 13 may be a core network device in a wireless communication system, for example, a mobility management entity (MME) in an evolved packet core (EPC). Alternatively, the core network device may be other core network devices, such as a serving gateway (SGW), a public data network gateway (PGW), a policy and charging rules function (PCRF), or a home subscriber server (HSS). Alternatively, the core network device 13 may be a core network device in 5G, for example, a policy control function (PCF), a session management function (SMF), an access and mobility management function (AMF), a unified data management (UDM), or a user plane function (UPF). The embodiment of the present disclosure does not limit the implementation form of the core network device 13.

[0039] As shown in FIG2 , an embodiment of the present disclosure provides an information processing method, which is executed by a terminal, wherein the method further includes:

[0040] S101: Send request information, where the request information is used to request bandwidth aggregation of positioning reference signals.

[0041] The terminal may be any type of communication device, a mobile terminal or a fixed terminal.

[0042] The terminal may be a mobile phone, a tablet computer, a smart office device, a smart home device, a vehicle-mounted device and / or an aircraft device.

[0043] For example, the terminal may send a request to the network device to request the network device to perform bandwidth aggregation on the positioning reference signals. By performing bandwidth aggregation on the positioning reference signals, the bandwidth for transmitting and receiving positioning reference signals can be effectively increased, achieving higher positioning accuracy.

[0044] The network device may be an access network device or a core network device; here, the access network device may be a base station of various types, for example, a third generation mobile communication (3 th Generation, 3G) network base stations, fourth generation mobile communications (4 th Generation, 4G) network base stations, fifth generation mobile communications (5 th Base stations of 5G (5th Generation) networks, or other evolved base stations.

[0045] It should be noted that the positioning reference signal is a reference signal that can be used to determine the spatial position of the terminal. For example, the positioning reference signal includes but is not limited to: a positioning reference signal (PRS) in the downlink and / or a sounding reference signal (SRS) in the uplink.

[0046] The terminal can measure the PRSs sent by multiple access network devices and report the measurement results to the core network device, which then locates the terminal based on the measurement results. It is understandable that the terminal can obtain information such as the reference signal time difference (RSTD) and / or reference signal received power (RSRP) of the PRSs by measuring the multiple PRSs received, and report the above information to the core network device; the core network device locates the terminal based on the known locations of the various access network devices and the above information.

[0047] Alternatively, the terminal may send SRSs to multiple access network devices, which then perform measurements based on the received SRSs and report the measurement results to the core network device. The core network device then locates the terminal based on the measurement results of the multiple access network devices. It is understood that the access network device can obtain information such as the RSRP, horizontal angle of arrival (AoA), and / or vertical angle of arrival (ZoA) of the SRS by measuring the received SRSs, and report the above information to the core network device. The core network device then locates the terminal based on the known locations of the access network devices and the above information.

[0048] In this embodiment of the present disclosure, the request information is used to request bandwidth aggregation of multiple positioning reference signals in the frequency domain. The bandwidth-aggregated positioning reference signals are equivalent to positioning reference signals with a larger bandwidth. The multiple positioning reference signals can be on different frequency resources or on different carriers.

[0049] The core network equipment includes but is not limited to a location management function (LMF).

[0050] It can be understood that according to the positioning principle, the larger the bandwidth of the positioning reference signal used for positioning, the higher the positioning accuracy will be. However, due to the maximum bandwidth of the carrier, the bandwidth of a single positioning reference signal cannot be effectively increased. Based on this, in the embodiment of the present disclosure, the terminal can send a request message to the network device to request the network device to perform bandwidth aggregation on multiple positioning reference signals, so that during the positioning process, the terminal and / or access network device measures multiple positioning reference signals as an aggregated, larger bandwidth positioning signal to achieve more accurate positioning of the terminal.

[0051] In some embodiments, the request information may further include resource location information of multiple positioning reference signals for bandwidth aggregation; the resource location information indicates the locations of wireless resources used to transmit the multiple positioning reference signals. The resource location information may include, but is not limited to, frequency domain parameters and / or time domain parameters.

[0052] Frequency domain parameters are used to indicate the frequency domain position of the positioning reference signal. In one embodiment, the frequency domain parameters may include, but are not limited to, a frequency domain reference point, bandwidth, bandwidth part (BWP), sub-carrier spacing (SCS), a starting physical resource block and / or a resource unit offset, etc.

[0053] The time domain parameters are used to indicate the time domain position of the positioning reference signal. In one embodiment, the time domain parameters may include but are not limited to: the starting time slot position, the starting symbol position, the number of occupied symbols, the number of transmissions and / or the transmission time interval, etc.

[0054] In some embodiments, the request information may also include information of antenna ports supporting positioning reference signal aggregation, etc.

[0055] In the embodiment of the present disclosure, a terminal sends a request message to a network device, requesting the network device to provide a positioning reference signal configuration that can perform bandwidth aggregation on multiple different frequency domain resources. Measuring the positioning reference signal after bandwidth aggregation will obtain a frequency gain, thereby improving the positioning accuracy of the terminal and reducing the impact of inaccurate terminal positioning on information transmission performance.

[0056] In some embodiments, the request information includes: a request for a positioning reference signal (PRS) on demand; or a request for a sounding reference signal (SRS).

[0057] In an embodiment of the present disclosure, the terminal sends an on-demand PRS request to the core network device, and uses the on-demand PRS request to request the core network device to provide multiple downlink positioning reference signals PRS that can perform bandwidth aggregation.

[0058] It should be noted that in order to better meet the positioning requirements of terminals, on-demand PRS is introduced in New Radio (NR) positioning. As shown in Figure 3, the specific process of NR positioning based on on-demand PRS includes:

[0059] Step 0: The core network device obtains the transmission and receiving point (TRP) information of multiple access network devices through the New Radio Positioning Protocol a (NRPPa);

[0060] For on-demand PRS requests initiated by terminals:

[0061] Step 1: The core network device provides a plurality of predefined PRS configurations to the terminal;

[0062] Step 2a: The terminal sends LPP request assistance data including an on-demand PRS request to the core network device;

[0063] On-demand PRS request initiated for core network equipment:

[0064] Step 2b: The core network device and the terminal exchange LPP messages to determine the configuration of the on-demand PRS;

[0065] In step 3, the core network device determines whether to send the PRS or whether to change the transmission characteristics of the PRS.

[0066] Step 4: The core network device sends an NRPPa PRS configuration request to multiple access network devices;

[0067] Step 5: Multiple access network devices send NRPPa PRS configuration responses to the core network device;

[0068] Step 6: The core network device sends an LPP provide assistance data message including an on-demand PRS response to the terminal.

[0069] In one embodiment, the on-demand PRS request includes at least one of the following: a PRS configuration requested by the terminal; and a PRS configuration identifier requested by the terminal.

[0070] It can be understood that the terminal can send an on-demand PRS request to the core network device according to its own needs, so that the core network device can provide the PRS configuration to the terminal according to the on-demand PRS request of the terminal; after obtaining the PRS configuration, the terminal receives the PRS based on the PRS configuration to complete the positioning measurement.

[0071] The terminal may also send a Sounding Reference Signal (SRS) request to the access network device, requesting the access network device to provide multiple uplink Sounding Reference Signals (SRSs) that can be bandwidth aggregated. In one embodiment, the SRS request includes at least one of the following: an SRS configuration requested by the terminal; and an SRS configuration identifier requested by the terminal.

[0072] Here, SRS is an uplink positioning reference signal, which is a positioning reference signal sent by the terminal to the access network device. Before sending the SRS, the terminal may first send an SRS request to the access network device so that the access network device can configure SRS resources for the terminal based on the SRS configuration or SRS configuration identifier in the SRS request of the terminal, so that the terminal can send the SRS and complete the positioning measurement.

[0073] In the embodiment of the present disclosure, the terminal sends an on-demand PRS request and / or SRS request to the network device, so as to request the network device to provide positioning reference signals on multiple different frequency domain resources that can be bandwidth aggregated through the on-demand PRS request and / or SRS request, so that the positioning reference signal after bandwidth aggregation has a larger bandwidth, thereby improving the positioning accuracy of the terminal.

[0074] In some embodiments, the request information includes at least one of the following:

[0075] Frequency information indicating frequency layers, carriers, frequency layer combinations and / or carrier combinations for bandwidth aggregation;

[0076] Priority information, indicating the priority of the corresponding frequency layer combination and / or the carrier combination;

[0077] A first identification ID includes a configuration ID, a resource set ID, and / or a resource ID associated with a positioning reference signal for which bandwidth aggregation is requested;

[0078] A second identifier ID includes a predefined positioning reference signal configuration, wherein the predefined positioning reference signal configuration is a positioning reference signal configuration configured with bandwidth aggregation;

[0079] The access device indication indicates the access device that performs bandwidth aggregation on the positioning reference signal.

[0080] In the embodiment of the present disclosure, the request information may include frequency information of multiple positioning reference signals for which bandwidth aggregation is requested.

[0081] Here, the frequency information is used to indicate the frequency layer, carrier, frequency layer combination and / or carrier combination of the positioning reference signals to be aggregated. In short, the frequency information can identify the frequency layer of the PRS to be bandwidth aggregated and / or the carrier of the SRS.

[0082] It should be noted that the frequency domain resources on the frequency layer or carrier are a collection of frequency domain resources used to transmit positioning reference signals. The terminal sends frequency information to the network device to indicate the frequency domain resource location of the positioning reference signal for which the terminal requests bandwidth aggregation.

[0083] In one embodiment, the frequency information may be carried by a bitmap, where each indicator bit in the bitmap corresponds to one frequency layer or carrier. It should be noted that the length of the bitmap depends on the number of frequency layers or carriers supported by the terminal. Each indicator bit in the bitmap corresponds to one frequency layer or carrier supported by the terminal; the indicator bit is used to indicate that the terminal requests bandwidth aggregation for that frequency layer or carrier.

[0084] Exemplarily, the indication bit in the bitmap is 1, which is used to indicate that the terminal requests bandwidth aggregation in the frequency layer or carrier; the indication bit in the bitmap is 0, which is used to indicate that the terminal requests not to perform bandwidth aggregation in the frequency layer or carrier.

[0085] In another embodiment, the frequency information may be carried by multiple bitmaps, each bitmap corresponding to a frequency layer combination or carrier combination.

[0086] It is understandable that the terminal sends frequency information to the network device based on one or more frequency layers or carriers supported by the terminal, so that the network device can know the frequency domain resource location of the positioning reference signal for which the terminal requests bandwidth aggregation.

[0087] In some embodiments, the frequency information includes: a frequency band indication indicating a frequency layer and / or carrier for bandwidth aggregation; and / or a frequency band combination indication indicating a frequency layer combination and / or carrier combination capable of bandwidth aggregation.

[0088] In the embodiments of the present disclosure, frequency information may include: a frequency band indicator and / or a frequency band combination indicator. The frequency band indicator is used to indicate multiple frequency layers and / or carriers of a bandwidth-aggregated positioning reference signal. The frequency band combination indicator is used to indicate multiple frequency layer combinations and / or carrier combinations of positioning reference signals capable of bandwidth aggregation; each frequency layer combination includes multiple frequency layers, and each carrier combination includes multiple carriers.

[0089] It can be understood that the terminal sends a frequency band indication to request the network device to perform bandwidth aggregation on multiple frequency layers and / or carriers indicated by the frequency band indication; and sends a frequency band combination indication to request the network device to perform bandwidth aggregation on multiple frequency layers within each frequency layer combination indicated by the frequency band combination indication, or requests the network device to perform bandwidth aggregation on multiple carriers within each carrier combination indicated by the frequency band combination indication.

[0090] In one embodiment, the frequency information of the PRS includes one of the following: the frequency band indication indicating the frequency layering of the bandwidth-aggregated PRS; the frequency band combination indication indicating the frequency layering combination of the bandwidth-aggregated PRS.

[0091] In another embodiment, the frequency information of the SRS includes one of the following: the frequency band indication indicating the carrier of the bandwidth-aggregated SRS; the frequency band combination indication indicating the carrier combination of the bandwidth-aggregated SRS.

[0092] In some embodiments, the request information may further include priority information, where the priority information indicates the priority corresponding to the frequency layer combination and / or the carrier combination.

[0093] It can be understood that for multiple frequency layer combinations and / or carrier combinations that can be bandwidth aggregated as indicated by the frequency information, the frequency layer combination and / or carrier combination with the highest priority is determined based on the priority information corresponding to each frequency layer combination and / or carrier combination, and the multiple frequency layers within the frequency layer combination are bandwidth aggregated, and / or the multiple carriers within the carrier combination are bandwidth aggregated.

[0094] In one embodiment, if the frequency information of the PRS includes the frequency band combination indication;

[0095] The on-demand PRS request information further includes priority information indicating the priority of the frequency layer combination of the PRS.

[0096] In another embodiment, if the frequency information of the SRS includes the frequency band combination indication;

[0097] The SRS request information further includes priority information indicating the priority of the SRS carrier combination.

[0098] In some embodiments, the request information may further include a first identification ID, including a configuration ID, a resource set ID, and / or a resource ID associated with the positioning reference signal for which bandwidth aggregation is requested.

[0099] The resource ID can be used to uniquely identify a positioning reference signal resource. A positioning reference signal resource is the minimum granularity of a positioning reference signal configuration. One positioning reference signal resource corresponds to a positioning reference signal transmission beam, carrier, or frequency layer.

[0100] The resource set ID can be used to uniquely identify a positioning reference signal resource set. A positioning reference signal resource set is a group of positioning reference signal resources for transmitting positioning reference signals. The positioning reference signal resources within a positioning reference signal resource set have the same period, number of symbols, etc. A positioning reference signal resource set may include one or more reference positioning signal resources.

[0101] The configuration ID can be used to uniquely identify the positioning reference signal configuration. Different positioning reference signal configurations have different configuration IDs.

[0102] Network equipment can send multiple predefined Positioning Reference Signal (PRS) configurations to a terminal. It is understood that each PRS configuration may meet different positioning requirements. Based on its own positioning requirements, the terminal can select one of these PRS configurations for positioning measurement. It should be noted that different PRS configurations may correspond to different PRS transmission periods, transmission bandwidths, and / or transmission resources.

[0103] As shown in FIG4 , an embodiment of the present disclosure provides an information processing method, which is executed by a terminal device and includes:

[0104] Step S201: receiving a first positioning reference signal configuration set sent by a network device; the first positioning reference signal configuration set includes a plurality of configuration IDs, resource set IDs and / or resource IDs associated with the positioning reference signals;

[0105] Step S202: Send a request message including a first identifier to a network device, where the first identifier includes a configuration ID, a resource set ID, and / or a resource ID associated with a positioning reference signal for which bandwidth aggregation is requested.

[0106] In an embodiment of the present disclosure, the first positioning reference signal configuration set may include a plurality of positioning reference signal configurations predefined by a network device for a terminal; the positioning reference signal configuration includes a configuration ID, a resource set ID and / or a resource ID associated with the corresponding positioning reference signal.

[0107] The network device sends a first positioning reference signal configuration set to the terminal, so that the terminal device selects the configuration ID, resource set ID and / or resource ID associated with the positioning reference signal that meets the needs of the terminal device based on multiple positioning reference signal configurations in the first positioning reference signal configuration set, and sends the configuration ID, resource set ID and / or resource ID associated with the positioning reference signal to the network device, and requests the network device to perform bandwidth aggregation on the positioning reference signal associated with the configuration ID, resource set ID and / or resource ID.

[0108] In some embodiments, the request information may further include a second identifier ID, including a predefined positioning reference signal configuration, wherein the predefined positioning reference signal configuration is a positioning reference signal configuration configured with bandwidth aggregation;

[0109] It should be noted that the second identifier ID can be used to indicate a predefined positioning reference signal configuration. It should be noted that the network device predefines multiple positioning reference signal configurations for the terminal (i.e., a second positioning reference signal configuration set). The second positioning reference signal configuration set includes at least one positioning reference signal configuration configured with bandwidth aggregation. Each positioning reference signal configuration in the second positioning reference signal configuration set has an identifier.

[0110] The terminal informs the network device of the positioning reference signal configuration requested by the terminal by sending a request message carrying the second identification ID; if the terminal needs to perform bandwidth aggregation on the positioning reference signal, the ID corresponding to the positioning reference signal configuration configured with bandwidth aggregation can be added to the request message to request the network device to perform bandwidth aggregation on the positioning reference signal; if the terminal does not need to perform bandwidth aggregation on the positioning reference signal, the ID corresponding to other positioning reference signal configurations can be added to the request message.

[0111] In one embodiment, the positioning reference signal configuration may include at least one of the following: a partial bandwidth BWP identifier ID corresponding to the positioning reference signal resource; a frequency layer ID corresponding to the positioning reference signal resource; an access network device ID corresponding to the positioning reference signal resource; a TRP ID corresponding to the positioning reference signal resource; a positioning reference signal resource set ID; and a positioning reference signal resource ID.

[0112] As shown in FIG5 , an embodiment of the present disclosure provides an information processing method, which is executed by a terminal device and includes:

[0113] Step S301: Receive a second positioning reference signal configuration set sent by a network device; the second positioning reference signal configuration set includes at least one positioning reference signal configuration configured with bandwidth aggregation.

[0114] Step S302: Send request information including a second identifier to the network device.

[0115] In an embodiment of the present disclosure, the second positioning reference signal configuration set may include a network device pre-defining multiple positioning reference signal configurations for the terminal; among the multiple positioning reference signal configurations, there is at least one positioning reference signal configuration associated with a positioning reference signal capable of bandwidth aggregation.

[0116] The network device sends the second positioning reference signal configuration set to the terminal, so that the terminal device selects a positioning reference signal configuration associated with a positioning reference signal for positioning measurement based on multiple positioning reference signal configurations in the second positioning reference signal configuration set.

[0117] If the second identifier carried by the terminal in the request information is the ID corresponding to the positioning reference signal configuration configured with bandwidth aggregation, it indicates that the terminal requests bandwidth aggregation for the positioning reference signals associated with the positioning reference signal configuration configured with bandwidth aggregation.

[0118] If the second identifier carried by the terminal in the request information is the ID corresponding to other positioning reference signal configurations in the second positioning reference signal configuration set, it means that the terminal requests to use the positioning reference signal corresponding to the positioning reference signal configuration for positioning measurement, but does not request to perform bandwidth aggregation on the positioning reference signal corresponding to the positioning reference signal configuration.

[0119] In some embodiments, the request information may further include an access device indication, indicating the access device that performs bandwidth aggregation on the positioning reference signal. It should be noted that the access device may be a base station or a TRP, and the access device indication may include: a base station ID and / or a TRP ID.

[0120] An access device may be associated with one or more positioning reference signal resource sets, and each positioning reference signal resource set may include one or more positioning reference signal resources.

[0121] The terminal may send request information including an access device indication to the network device to inform the network device that the terminal requests bandwidth aggregation of the positioning reference signal associated with the access device corresponding to the access device indication.

[0122] In one embodiment, the terminal may send request information to the network device; wherein the request information includes: frequency information, priority information and / or access device indication.

[0123] It can be understood that when the network device does not pre-configure the positioning reference signal for the terminal, that is, the network device will not send the first positioning reference signal configuration set or the second positioning reference signal configuration set to the terminal, the terminal can directly send a request message containing frequency information, priority information and / or access device indication to the network device to request the network device to determine multiple positioning reference signals for bandwidth aggregation based on the request message to complete the bandwidth aggregation of multiple positioning reference signals.

[0124] It should be noted that the first identifier (or second identifier) ​​is the ID corresponding to a positioning reference signal configuration selected by the terminal from multiple positioning reference signal configurations in the first positioning reference signal configuration set (or second positioning reference signal configuration set) sent by the network device; when the network device has not pre-configured a positioning reference signal for the terminal, the request information sent by the terminal will not carry the first identifier or the second identifier. At this time, in order to achieve bandwidth aggregation of multiple positioning reference signals, the terminal can directly send a request message containing frequency information, priority information and / or access device indication, that is, the terminal actively informs the network device of its own configuration requirements for the positioning reference signal, and requests the network device to configure the required positioning reference signal resources for it; so as to achieve bandwidth aggregation of multiple positioning reference signals and meet the positioning requirements of the terminal.

[0125] In the embodiment of the present disclosure, by carrying frequency information, priority information, a first identification ID, a second identification ID, and / or an access device indication in a request message, the network device determines, based on the request information, multiple positioning reference signal resources for bandwidth aggregation requested by the terminal, thereby completing the configuration of the multiple positioning reference signal resources and realizing bandwidth aggregation of the multiple positioning reference signals. In a subsequent positioning process, positioning measurements are performed using the bandwidth-aggregated positioning reference signals, thereby improving the positioning accuracy of the terminal.

[0126] In some embodiments, the frequency information includes at least one of the following: a frequency band number; an offset and / or bandwidth relative to a reference frequency value; and an identifier of a partial bandwidth BWP.

[0127] In the disclosed embodiment, the frequency band number indicates the frequency band of the positioning reference signal for transmission bandwidth aggregation. The offset relative to the reference frequency value may be the frequency offset between a reference frequency point and a measurement frequency point. In one embodiment, the reference frequency point may be reference point A or reference point B; the offset relative to the reference frequency value may be the frequency offset of point A or the frequency offset of point B.

[0128] The identifier of the BWP is used to indicate the BWP where the frequency layer of the bandwidth aggregation and / or the carrier is located, or to indicate the position of the frequency layer of the bandwidth aggregation and / or the carrier on the BWP.

[0129] The terminal sends frequency information including the frequency band number, the offset relative to the reference frequency value, the bandwidth and / or the BWP identifier to inform the network device that the terminal requests bandwidth aggregation for the positioning reference signal associated with the above frequency information so that the network device can configure resources for the positioning reference signal associated with the above frequency information.

[0130] In some embodiments, at least one of the following parameters of any two positioning reference signals subjected to bandwidth aggregation is the same: resource period; resource set period; bandwidth; number of resources occupied by one positioning reference signal; and repetition parameter of the positioning reference signal.

[0131] It should be noted that resource periodicity, resource set periodicity, resource bandwidth, the number of resources occupied by one positioning reference signal, and resource repetition factor are configuration parameters of the positioning reference signal.

[0132] The prerequisite for bandwidth aggregation of two positioning reference signals is that the parameter values ​​of one or more configuration parameters of the resource period, resource set period, bandwidth, number of resources occupied by the positioning reference signals, and repetition parameters of the two positioning reference signals are all the same.

[0133] In an embodiment of the present disclosure, a terminal sends a request message to request a network device to configure resources for any two positioning reference signals for bandwidth aggregation requested by the terminal, so that the configuration parameters of the resources of any two positioning reference signals for bandwidth aggregation meet the prerequisites for bandwidth aggregation, so as to perform bandwidth aggregation on any two positioning reference signals requested by the terminal.

[0134] In some embodiments, the number of resources occupied by a positioning reference signal includes: the number of time units occupied by a positioning reference signal; wherein the time unit includes: a symbol, a mini-slot or a time slot; or, the number of comb resources occupied by a positioning reference signal.

[0135] In the embodiment of the present disclosure, the number of time units occupied by a positioning reference signal is used to describe the number of time domain resources occupied by the positioning reference signal; the time unit includes: a symbol, a mini-slot, or a time slot.

[0136] The positioning reference signal resource may have a comb structure, and the terminal may send a positioning reference signal on one of the comb structures. The comb resource number (Comb Size N) is used to describe the number of inner subcarriers carrying the positioning reference signal in each symbol period of the positioning reference signal resource configuration. For example, if the number of comb resources occupied by the positioning reference signal is 4, it means that every 4th subcarrier of the positioning symbol carries the positioning reference signal.

[0137] In the disclosed embodiment, after receiving the request information, the network device performs resource configuration for any two positioning reference signals for bandwidth aggregation based on the terminal's request by sending the request information, so that the number of time units or comb resources occupied by any two positioning reference signals is the same. This ensures that the configuration parameters of the resources of any two positioning reference signals for which bandwidth aggregation is requested meet the prerequisites for bandwidth aggregation, thereby enabling bandwidth aggregation to be performed on any two positioning reference signals requested by the terminal.

[0138] In some embodiments, sending the request information includes:

[0139] Sending a request message for a downlink on-demand positioning reference signal (PRS) to a core network device; or

[0140] Send uplink sounding reference signal (SRS) request information to the access network device.

[0141] In the embodiment of the present disclosure, the positioning reference signal may include: an uplink sounding reference signal SRS and a downlink on-demand positioning reference signal PRS.

[0142] Since the SRS is sent by the terminal to the access network device, in order for the access network device to receive multiple bandwidth-aggregated SRSs and perform positioning measurements based on the multiple bandwidth-aggregated SRSs, the terminal can send SRS request information to the access network device so that the access network device can configure SRS resources for the terminal based on the SRS request information so that the terminal can send SRS and complete positioning measurements.

[0143] Since the on-demand PRS is sent to the terminal by the access network device, in order to enable the terminal to receive multiple bandwidth-aggregated on-demand PRSs and perform positioning measurements based on the multiple bandwidth-aggregated on-demand PRSs, the terminal can send on-demand PRS request information to the core network device according to its own needs, so that the core network device can provide the PRS configuration to the terminal based on the on-demand PRS request information; after obtaining the PRS configuration, the terminal receives the on-demand PRS based on the PRS configuration and completes the positioning measurement.

[0144] In some embodiments, the request information is carried in a Long Term Evolution Positioning Protocol (LPP) assistance data request message sent to a core network device.

[0145] In an embodiment of the present disclosure, the terminal may add the request information of the on-demand PRS to the LPP request auxiliary data message, and then send the LPP request auxiliary data message to the core network device, so that the core network device obtains the request information of the on-demand PRS from the LPP request auxiliary data message.

[0146] It should be noted that the LPP message is a signaling message for exchanging positioning capability and other related information between the terminal and the core network equipment. Here, the terminal can carry on-demand PRS request information in the uplink LPP message.

[0147] In one embodiment, an LPP assistance data request message includes one or more information fields for carrying a PRS request message. The information fields may include multiple bits, each of which may be used to indicate frequency information, priority information, a first identifier, a second identifier, and / or an access device indicator for multiple positioning reference signals aggregated in bandwidth.

[0148] In an embodiment of the present disclosure, the terminal adds the request information of the on-demand PRS to a dedicated signaling message. While the terminal and the core network device transmit the dedicated signaling message, the terminal sends the request information of the on-demand PRS to the core network device to request the core network device to perform bandwidth aggregation on the PRS. In this way, no additional signaling or message is required to carry the request information, which can reduce the signaling overhead.

[0149] In some embodiments, the request information sent to the access network device is carried in a radio resource control RRC message; or in a control unit CE of a medium access control MAC.

[0150] In an embodiment of the present disclosure, the terminal may add SRS request information to an RRC message, and then send the RRC message carrying the SRS request information to the access network device, so that the access network device obtains the SRS request information from the RRC message.

[0151] It should be noted that the RRC message is a signaling message required for establishing, re-establishing, maintaining and releasing an RRC connection between a terminal and an access network device. Here, the terminal may carry SRS request information in the uplink RRC message.

[0152] It is understandable that the terminal can carry SRS request information with different contents by setting any one or more bits in the RRC message to different bit values.

[0153] The terminal may also add the SRS request information to the MAC CE, and then send the MAC CE to the terminal, so that the access network device obtains the SRS request information from the MAC CE.

[0154] It should be noted that MAC CE is a signaling message required for exchanging MAC layer control information between a terminal and an access network device.

[0155] In an embodiment of the present disclosure, the terminal adds the SRS request information to a dedicated signaling message. While the terminal and the access network device are transmitting the dedicated signaling message, the terminal sends the SRS request information to the access network device to request the access network device to perform bandwidth aggregation on the SRS. In this way, no additional signaling or message is required to carry the request information, thereby reducing the signaling overhead.

[0156] As shown in FIG6 , an embodiment of the present disclosure provides an information processing method, which is executed by a network device and includes:

[0157] Step S401: Receive request information, where the request information is used to perform bandwidth aggregation on positioning reference signals.

[0158] In the embodiment of the present disclosure, the network device receives request information sent by the terminal.

[0159] In this embodiment of the present disclosure, the request information is used to request bandwidth aggregation of multiple positioning reference signals in the frequency domain. The bandwidth-aggregated positioning reference signals are equivalent to positioning reference signals with a larger bandwidth. The multiple positioning reference signals can be on different frequency resources or on different carriers.

[0160] It is understandable that, according to the positioning principle, the larger the bandwidth of the positioning reference signal used for positioning, the higher the positioning accuracy will be. However, due to the limitation of the maximum bandwidth of the carrier, the bandwidth of a single positioning reference signal cannot be effectively increased. Based on this, the network device receives the request information and, based on the request of the terminal, aggregates the bandwidth of multiple positioning reference signals. Therefore, during the positioning process, the terminal and / or access network device measures multiple positioning reference signals as an aggregated, larger bandwidth positioning signal to achieve more accurate positioning of the terminal.

[0161] In some embodiments, the request information may further include resource location information of multiple positioning reference signals for bandwidth aggregation; the resource location information indicates the locations of wireless resources used to transmit the multiple positioning reference signals. The resource location information may include, but is not limited to, frequency domain parameters and / or time domain parameters.

[0162] In some embodiments, the request information may also include information of antenna ports supporting positioning reference signal aggregation, etc.

[0163] In the embodiment of the present disclosure, a network device receives a request message sent by a terminal. Based on the request message, the network device performs bandwidth aggregation on positioning reference signals on multiple different frequency domain resources. Frequency gain is obtained by measuring the positioning reference signals after bandwidth aggregation, thereby improving the positioning accuracy of the terminal and reducing the impact of inaccurate terminal positioning on information transmission performance.

[0164] In some embodiments, the request information includes: an on-demand positioning reference signal PRS request; or a sounding reference signal SRS request.

[0165] In an embodiment of the present disclosure, a network device may receive an on-demand positioning reference signal (PRS) request sent by a terminal, and based on the on-demand PRS request from the terminal, perform bandwidth aggregation on multiple downlink positioning reference signals (PRSs). Here, the network device may be a core network device.

[0166] In one embodiment, the on-demand PRS request includes at least one of the following: a PRS configuration requested by the terminal; and a PRS configuration identifier requested by the terminal.

[0167] After receiving the on-demand PRS request, the core network device provides the PRS configuration to the terminal according to the on-demand PRS request of the terminal; after obtaining the PRS configuration, the terminal receives the PRS based on the PRS configuration and completes the positioning measurement.

[0168] The network device receives a sounding reference signal (SRS) request sent by a terminal, and based on the SRS request of the terminal, performs bandwidth aggregation on multiple uplink sounding reference signals (SRS). Here, the network device may be an access network device.

[0169] In one embodiment, the SRS request includes at least one of the following: an SRS configuration requested by the terminal; and an SRS configuration identifier requested by the terminal.

[0170] Here, the access network device receives the SRS request and configures SRS resources for the terminal according to the SRS configuration or SRS configuration identifier in the SRS request of the terminal, so that the terminal sends the SRS and completes the positioning measurement.

[0171] In the embodiment of the present disclosure, the network device receives an on-demand PRS request and / or SRS request, and based on the on-demand PRS request and / or SRS request of the terminal, performs bandwidth aggregation on the positioning reference signals on multiple different frequency domain resources, so that the positioning reference signal after bandwidth aggregation has a larger bandwidth, thereby improving the positioning accuracy of the terminal.

[0172] In some embodiments, the request information includes at least one of the following:

[0173] Frequency information indicating frequency layers, carriers, frequency layer combinations and / or carrier combinations for bandwidth aggregation;

[0174] Priority information, indicating the priority of the corresponding frequency layer combination and / or the carrier combination;

[0175] A first identification ID includes a configuration ID, a resource set ID, and / or a resource ID associated with a positioning reference signal for which bandwidth aggregation is requested;

[0176] A second identifier ID includes a predefined positioning reference signal configuration, wherein the predefined positioning reference signal configuration is a positioning reference signal configuration configured with bandwidth aggregation;

[0177] The access device indication indicates the access device that performs bandwidth aggregation on the positioning reference signal.

[0178] In the embodiment of the present disclosure, the request information may include frequency information of multiple positioning reference signals for which bandwidth aggregation is requested.

[0179] Here, the frequency information is used to indicate the frequency layer, carrier, frequency layer combination and / or carrier combination of the positioning reference signals to be aggregated. In short, the frequency information can identify the frequency layer of the PRS to be bandwidth aggregated and / or the carrier of the SRS.

[0180] It should be noted that the frequency domain resources on the frequency layer or carrier are a collection of frequency domain resources used to transmit positioning reference signals. The network device can determine the frequency domain resource location of the positioning reference signal for which the terminal requests bandwidth aggregation based on the frequency information sent by the terminal.

[0181] In one embodiment, the frequency information may be carried by a bitmap, where one indicator bit in the bitmap corresponds to one frequency layer or carrier. It should be noted that the length of the bitmap depends on the number of frequency layers or carriers supported by the terminal. Each indicator bit in the bitmap corresponds to a frequency layer or carrier supported by the terminal; wherein the indicator bit is used to indicate that the terminal requests bandwidth aggregation for the frequency layer or carrier. Exemplarily, the indicator bit in the bitmap is 1, indicating that the terminal requests bandwidth aggregation for the frequency layer or carrier; the indicator bit in the bitmap is 0, indicating that the terminal requests not to perform bandwidth aggregation for the frequency layer or carrier.

[0182] In another embodiment, the frequency information may be carried by multiple bitmaps, each bitmap corresponding to a frequency layer combination or carrier combination. It is understood that the terminal sends frequency information to the network device based on one or more frequency layers or carriers supported by the terminal, so that the network device can obtain the frequency domain resource location of the positioning reference signal for which the terminal requests bandwidth aggregation.

[0183] In some embodiments, the frequency information includes: a frequency band indication indicating a frequency layer and / or carrier for bandwidth aggregation; and / or a frequency band combination indication indicating a frequency layer combination and / or carrier combination capable of bandwidth aggregation.

[0184] In the embodiments of the present disclosure, frequency information may include: a frequency band indicator and / or a frequency band combination indicator. The frequency band indicator is used to indicate multiple frequency layers and / or carriers of a bandwidth-aggregated positioning reference signal. The frequency band combination indicator is used to indicate multiple frequency layer combinations and / or carrier combinations of positioning reference signals capable of bandwidth aggregation; each frequency layer combination includes multiple frequency layers, and each carrier combination includes multiple carriers.

[0185] It is understood that the network device receives the frequency band indication and, based on the frequency band indication, determines the multiple frequency layers and / or carriers for which the terminal requests bandwidth aggregation. The network device receives the frequency band combination indication and, based on the frequency band combination indication, determines the multiple frequency layer combinations and / or carrier combinations for which the terminal requests bandwidth aggregation.

[0186] In one embodiment, the frequency information of the PRS includes one of the following: the frequency band indication indicating the frequency layering of the PRS for bandwidth aggregation; the frequency band combination indication indicating the frequency layering combination of the PRS capable of bandwidth aggregation;

[0187] In another embodiment, the frequency information of the SRS includes one of the following: the frequency band indication indicating the carrier of the bandwidth-aggregated SRS; the frequency band combination indication indicating the carrier combination of the bandwidth-aggregated SRS.

[0188] In some embodiments, the request information may further include priority information, where the priority information indicates the priority of the corresponding frequency layer combination and / or the carrier combination. It is understandable that, for multiple frequency layer combinations and / or carrier combinations capable of bandwidth aggregation indicated by the frequency information, the frequency layer combination and / or carrier combination with the highest priority is determined based on the priority information corresponding to each frequency layer combination and / or carrier combination, and bandwidth aggregation is performed on multiple frequency layers within the frequency layer combination, and / or bandwidth aggregation is performed on multiple carriers within the carrier combination.

[0189] In one embodiment, if the frequency information of the PRS includes the frequency band combination indication;

[0190] The PRS request information further includes priority information indicating the priority of the frequency layer combination of the PRS.

[0191] In another embodiment, if the frequency information of the SRS includes the frequency band combination indication;

[0192] The SRS request information further includes priority information indicating the priority of the SRS carrier combination.

[0193] In some embodiments, the request information may further include a first identification ID, including a configuration ID, a resource set ID, and / or a resource ID associated with the positioning reference signal for which bandwidth aggregation is requested.

[0194] The resource ID can be used to uniquely identify a positioning reference signal resource. A positioning reference signal resource is the minimum granularity of a positioning reference signal configuration. One positioning reference signal resource corresponds to a positioning reference signal transmission beam, carrier, or frequency layer.

[0195] The resource set ID can be used to uniquely identify a positioning reference signal resource set. A positioning reference signal resource set is a group of positioning reference signal resources for transmitting positioning reference signals. The positioning reference signal resources within a positioning reference signal resource set have the same period, number of symbols, etc. A positioning reference signal resource set may include one or more reference positioning signal resources.

[0196] The configuration ID can be used to uniquely identify the positioning reference signal configuration. Different positioning reference signal configurations have different configuration IDs.

[0197] The network device can send multiple pre-defined sets of positioning reference signal configurations to the terminal; it is understandable that each set of positioning reference signal configurations may meet different positioning requirements; the terminal can select one set of positioning reference signal configurations from multiple sets of positioning reference signal configurations for positioning measurement based on its own positioning requirements.

[0198] It should be noted that different positioning reference signal configurations correspond to different positioning reference signal transmission periods, transmission bandwidths and / or transmission resources.

[0199] In some embodiments, the request information may further include a second identifier ID, including a predefined positioning reference signal configuration, wherein the predefined positioning reference signal configuration is a positioning reference signal configuration configured with bandwidth aggregation;

[0200] It should be noted that the second identifier ID can be used to indicate a predefined positioning reference signal configuration. It should be noted that the network device predefines multiple positioning reference signal configurations for the terminal (i.e., a second positioning reference signal configuration set). The second positioning reference signal configuration set includes at least one positioning reference signal configuration configured with bandwidth aggregation. Each positioning reference signal configuration in the second positioning reference signal configuration set has an identifier.

[0201] It can be understood that if the second identification ID in the request information is the ID corresponding to the positioning reference signal configuration configured with bandwidth aggregation, it means that the terminal requests bandwidth aggregation of the positioning reference signal; if the second identification ID in the request information is the ID corresponding to other positioning reference signal configurations, it means that the terminal does not request bandwidth aggregation of the positioning reference signal.

[0202] In one embodiment, the positioning reference signal configuration may include at least one of the following: a bandwidth part (BWP) identifier ID corresponding to the positioning reference signal resource; a frequency layer ID corresponding to the positioning reference signal resource; an access network device ID corresponding to the positioning reference signal resource; a TRP ID corresponding to the positioning reference signal resource; a positioning reference signal resource set ID; and a positioning reference signal resource ID.

[0203] In some embodiments, the request information may further include an access device indication, indicating the access device that performs bandwidth aggregation on the positioning reference signal. It should be noted that the access device may be a base station or a TRP, and the access device indication may include: a base station ID and / or a TRP ID.

[0204] An access device may be associated with one or more positioning reference signal resource sets, and each positioning reference signal resource set may include one or more positioning reference signal resources.

[0205] The network device receives the request information including the access device indication, and based on the access device indication, performs bandwidth aggregation on the positioning reference signal associated with the access device requested by the terminal.

[0206] In the embodiment of the present disclosure, by carrying frequency information, priority information, a first identification ID, a second identification ID, and / or an access device indication in a request message, the network device determines, based on the request information, multiple positioning reference signal resources for bandwidth aggregation requested by the terminal, thereby completing the configuration of the multiple positioning reference signal resources and realizing bandwidth aggregation of the multiple positioning reference signals. In a subsequent positioning process, positioning measurements are performed using the bandwidth-aggregated positioning reference signals, thereby improving the positioning accuracy of the terminal.

[0207] In some embodiments, the frequency information includes at least one of the following: a frequency band number; an offset and / or bandwidth relative to a reference frequency value; and an identifier of a partial bandwidth BWP.

[0208] In the disclosed embodiment, the frequency band number indicates the frequency band of the positioning reference signal for transmission bandwidth aggregation. The offset relative to the reference frequency value may be the frequency offset between a reference frequency point and a measurement frequency point. In one embodiment, the reference frequency point may be reference point A or reference point B; the offset relative to the reference frequency value may be the frequency offset of point A or the frequency offset of point B.

[0209] The identifier of the BWP is used to indicate the BWP where the frequency layer of the bandwidth aggregation and / or the carrier is located, or to indicate the position of the frequency layer of the bandwidth aggregation and / or the carrier on the BWP.

[0210] The terminal sends frequency information including the frequency band number, the offset relative to the reference frequency value, the bandwidth and / or the BWP identifier to inform the network device that the terminal requests bandwidth aggregation for the positioning reference signal associated with the above frequency information so that the network device can configure resources for the positioning reference signal associated with the above frequency information.

[0211] In some embodiments, the method further comprises:

[0212] Sending a predefined first positioning reference signal configuration set; the first positioning reference signal configuration set includes a plurality of configuration IDs, resource set IDs and / or resource IDs associated with the positioning reference signals; or,

[0213] A predefined second positioning reference signal configuration set is sent; wherein the second positioning reference signal configuration set includes at least one positioning reference signal configuration configured with bandwidth aggregation.

[0214] It should be noted that the first positioning reference signal configuration set may include multiple sets of positioning reference signal configurations pre-defined by the network device for the terminal; the positioning reference signal configuration includes the corresponding positioning reference signal associated configuration ID, resource set ID and / or resource ID.

[0215] The network device sends a first positioning reference signal configuration set to the terminal, so that the terminal device selects the configuration ID, resource set ID and / or resource ID associated with the positioning reference signal for positioning measurement based on multiple positioning reference signal configurations in the first positioning reference signal configuration set, and carries the configuration ID, resource set ID and / or resource ID associated with the positioning reference signal in the request information, and sends the request information to the network device to request the network device to perform bandwidth aggregation on the positioning reference signal associated with the configuration ID, resource set ID and / or resource ID.

[0216] The second positioning reference signal configuration set may include multiple positioning reference signal configurations predefined by the network device for the terminal; and a positioning reference signal associated with at least one positioning reference signal configuration among the multiple positioning reference signal configurations can perform bandwidth aggregation.

[0217] The network device sends the second positioning reference signal configuration set to the terminal, so that the terminal device selects a positioning reference signal configuration associated with a positioning reference signal for positioning measurement based on multiple positioning reference signal configurations in the second positioning reference signal configuration set.

[0218] If the second identification ID in the request information received by the network device is the ID corresponding to the positioning reference signal configuration configured with bandwidth aggregation, it indicates that the terminal requests bandwidth aggregation for the positioning reference signals associated with the positioning reference signal configuration configured with bandwidth aggregation.

[0219] If the second identification ID in the request information received by the network device is the ID corresponding to another positioning reference signal configuration in the second positioning reference signal configuration set, it means that the terminal requests to use the positioning reference signal corresponding to the positioning reference signal configuration for positioning measurement, but does not request to perform bandwidth aggregation on the positioning reference signal corresponding to the positioning reference signal configuration. As shown in Figure 7, an embodiment of the present disclosure provides an information processing method, which is executed by a network device, and the method includes:

[0220] Step S501: configuring parameters for any two positioning reference signals for bandwidth aggregation;

[0221] Among them, at least one of the following parameters of any two positioning reference signals after parameter configuration is the same: resource period; resource set period; bandwidth; number of resources occupied by one positioning reference signal; repetition parameter of the positioning reference signal.

[0222] It should be noted that resource periodicity, resource set periodicity, resource bandwidth, the number of resources occupied by one positioning reference signal, and resource repetition factor are configuration parameters of the positioning reference signal.

[0223] The prerequisite for bandwidth aggregation of two positioning reference signals is that the parameter values ​​of one or more configuration parameters of the resource period, resource set period, bandwidth, number of resources occupied by the positioning reference signals, and repetition parameters of the two positioning reference signals are all the same.

[0224] In an embodiment of the present disclosure, a network device receives request information and, based on the request information, performs resource configuration for any two positioning reference signals for which bandwidth aggregation is requested by a terminal, such that configuration parameters of the resources of any two positioning reference signals for which bandwidth aggregation is requested meet prerequisites for bandwidth aggregation, thereby enabling bandwidth aggregation to be performed on any two positioning reference signals requested by the terminal.

[0225] In some embodiments, the number of resources occupied by a positioning reference signal includes: the number of time units occupied by a positioning reference signal; wherein the time unit includes: a symbol, a mini-slot or a time slot; or, the number of comb resources occupied by a positioning reference signal.

[0226] In the embodiment of the present disclosure, the number of time units occupied by a positioning reference signal is used to describe the number of time domain resources occupied by the positioning reference signal; the time unit includes: a symbol, a mini-slot, or a time slot.

[0227] The positioning reference signal resource may have a comb structure, and the terminal may send a positioning reference signal on one of the comb structures. The comb resource number (Comb Size N) is used to describe the number of inner subcarriers carrying the positioning reference signal in each symbol period of the positioning reference signal resource configuration. For example, if the number of comb resources occupied by the positioning reference signal is 4, it means that every 4th subcarrier of the positioning symbol carries the positioning reference signal.

[0228] In an embodiment of the present disclosure, based on the request information of a terminal, a network device configures resources for any two positioning reference signals for bandwidth aggregation so that the number of time units or comb resources occupied by any two positioning reference signals is the same. This ensures that the configuration parameters of the resources of any two positioning reference signals for which bandwidth aggregation is requested meet the prerequisites for bandwidth aggregation, allowing bandwidth aggregation to be performed on any two positioning reference signals requested by the terminal.

[0229] In some embodiments, the receiving request information includes:

[0230] Receiving downlink on-demand positioning reference signal PRS request information; wherein the network device is a core network device;

[0231] Receive uplink sounding reference signal SRS request information; wherein the network device is an access network device.

[0232] In the embodiment of the present disclosure, the positioning reference signal may include: an uplink sounding reference signal SRS and a downlink on-demand positioning reference signal PRS.

[0233] Since the SRS is sent by the terminal to the access network device, in order for the access network device to receive multiple bandwidth-aggregated SRSs and perform positioning measurements based on the multiple bandwidth-aggregated SRSs, the terminal can send SRS request information to the access network device so that the access network device can configure SRS resources for the terminal based on the SRS request information so that the terminal can send SRS and complete positioning measurements.

[0234] Since the on-demand PRS is sent to the terminal by the access network device, in order to enable the terminal to receive multiple bandwidth-aggregated on-demand PRSs and perform positioning measurements based on the multiple bandwidth-aggregated on-demand PRSs, the terminal can send on-demand PRS request information to the core network device according to its own needs, so that the core network device can provide the PRS configuration to the terminal based on the on-demand PRS request information; after obtaining the PRS configuration, the terminal receives the on-demand PRS based on the PRS configuration and completes the positioning measurement.

[0235] In some embodiments, the on-demand PRS request information is carried in a Long Term Evolution Positioning Protocol (LPP) request assistance data message.

[0236] In an embodiment of the present disclosure, the terminal may add the request information of the on-demand PRS to the LPP request auxiliary data message. After the core network device receives the LPP request auxiliary data message sent by the terminal, it obtains the request information of the on-demand PRS from the LPP request auxiliary data message to perform bandwidth aggregation on multiple PRSs based on the request of the terminal.

[0237] It should be noted that the LPP message is a signaling message for exchanging positioning capability and other related information between the terminal and the core network equipment. Here, the terminal can carry on-demand PRS request information in the uplink LPP message.

[0238] In one embodiment, an LPP assistance data request message includes one or more information fields for carrying a PRS request message. The information fields may include multiple bits, each of which may be used to indicate frequency information, priority information, a first identifier, a second identifier, and / or an access device indicator for multiple positioning reference signals aggregated in bandwidth.

[0239] In the embodiment of the present disclosure, by adding request information to a dedicated signaling message, while the terminal and the core network device transmit the dedicated signaling message, the request information of the on-demand PRS is sent to the core network device to request the core network device to perform bandwidth aggregation on the PRS. In this way, no additional signaling or message is required to carry the request information, which can reduce the signaling overhead.

[0240] In some embodiments, the SRS request information is carried in a radio resource control RRC message; or in a control element CE of a medium access control MAC.

[0241] In the embodiment of the present disclosure, by adding SRS request information to the RRC message, the access network device obtains the SRS request information from the RRC message after receiving the RRC message, so as to perform bandwidth aggregation on multiple SRSs based on the request of the terminal.

[0242] It should be noted that the RRC message is a signaling message required for establishing, re-establishing, maintaining and releasing an RRC connection between a terminal and an access network device. Here, the terminal may carry SRS request information in the uplink RRC message.

[0243] It can be understood that any one or more bits in the RRC message can be set to different bit values ​​to carry SRS request information with different contents.

[0244] By adding the SRS request information to the MAC CE, the access network device obtains the SRS request information from the MAC CE after receiving the MAC CE, so as to perform bandwidth aggregation on multiple SRSs based on the request of the terminal.

[0245] It should be noted that MAC CE is a signaling message required for exchanging MAC layer control information between a terminal and an access network device.

[0246] In the embodiment of the present disclosure, by adding the SRS request information into a dedicated signaling message, the SRS request information is sent to the access network device while the terminal and the access network device transmit the dedicated signaling message to request the access network device to perform bandwidth aggregation on the SRS. In this way, no additional signaling or message carrying the request information is required, which can reduce the signaling overhead.

[0247] In one embodiment, the terminal sends positioning reference signal request information to the network device.

[0248] The terminal may send a request message to the network device in the following ways:

[0249] The terminal sends a request message for a downlink on-demand positioning reference signal (PRS) to the core network device;

[0250] The terminal sends request information for an uplink sounding reference signal SRS to the access network device.

[0251] Regarding the request information of the on-demand PRS, the terminal may carry the request information of the on-demand PRS in the LPP request assistance data message.

[0252] The on-demand PRS request can be used as the on-demand PRS request information, and the LPP request assistance data message can be used to carry the on-demand PRS request; or a new information field can be added to the LPP request assistance data message to carry the on-demand PRS request information.

[0253] For example, an on-demand PRS request may be defined as:

[0254] It should be noted that NR-On-Demand-DL-PRS-Request-r17 is an on-demand PRS request; DL-PRS-StartTime-and-Duration-r17 is the start time and duration parameters of the downlink PRS; NR-On-Demand-DL-PRS-Information-r17 is the on-demand downlink PRS information parameter; dl-prs-configuration-id-PrefList-r17 is the predefined downlink PRS configuration identifier list parameter; DL-PRS-Configuration-ID-r17 is the downlink PRS configuration identifier requested by the terminal.

[0255] The start time and duration parameters of the downlink PRS can be defined as:
