[0032] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: several UEs 11, several access devices 12, and several core network devices 13.

[0033] UE 11 can be a device that provides voice and / or data connectivity to a user. UE 11 can communicate with one or more core networks via a Radio Access Network (RAN). UE 11 can be an IoT UE, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT UE. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, UE 11 can also be a device in an unmanned aerial vehicle (UAV). Alternatively, UE 11 can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, UE 11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0034] Access device 12 can be a network-side device in a wireless communication system. This wireless communication system can be a 4G system (also known as Long Term Evolution, LTE); or it can be a 5G system (also known as a New Radio, NR, or 5G NR system). Alternatively, it can be the next generation after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.

[0035] The access device 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, the access device 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the access device 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the access device 12.

[0036] Access device 12 and UE 11 can establish a wireless connection 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, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0037] Several access network devices 12 are connected to core network devices 13. The core network device 13 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, the core network device can 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); or the core network device 13 can be a core network device in 5G, such as 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 implementation of the core network device 13 is not limited in this embodiment.

[0038] like Figure 2 As shown, this embodiment of the disclosure provides an information processing method executed by a terminal, wherein the method further includes:

[0039] S101, Send request information, wherein the request information is used to request bandwidth aggregation of the positioning reference signal.

[0040] This terminal can be any type of communication device. It can be a mobile terminal or a fixed terminal.

[0041] The terminal can be a mobile phone, tablet computer, smart office equipment, smart home equipment, vehicle equipment and / or flight equipment.

[0042] For example, a terminal may send a request to a network device to request the network device to perform bandwidth aggregation on the positioning reference signal. By performing bandwidth aggregation on the positioning reference signal, the bandwidth for transmitting and receiving the positioning reference signal can be effectively increased, thereby achieving higher positioning accuracy.

[0043] The network device can be an access network device or a core network device; here, the access network device can be various types of base stations, such as third-generation mobile communication (3G) base stations. th Base stations for Generation 3G (3G) networks and fourth-generation mobile communication (4G) th Base stations for Generation 4G (4G) networks and fifth-generation mobile communication (5G) th Base stations for Generation (5G) networks or other evolved base stations.

[0044] It should be noted that the positioning reference signal is a reference signal that can be used to determine the spatial location of the terminal. For example, the positioning reference signal includes, but is not limited to, the downlink positioning reference signal (PRS) and / or the uplink sounding reference signal (SRS).

[0045] The terminal can measure the PRS (Pulse Signal Reduction) 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 understood that by measuring the received multiple PRS, the terminal can obtain information such as the reference signal time difference (RSTD) and / or reference signal receiving power (RSRP) of the PRS, and report this information to the core network device. The core network device then locates the terminal based on the known locations of each access network device and the aforementioned information.

[0046] Alternatively, the terminal can send SRS to multiple access network devices. The access network devices then perform measurements based on the received SRS and report the results to the core network device. The core network device then locates the terminal based on the measurement results from the multiple access network devices. It is understood that the access network devices, upon receiving the SRS measurements, can obtain information such as the RSRP, azimuth of arrival (AoA), and / or zenith of arrival (ZoA), and report this information to the core network device. The core network device then locates the terminal based on the known locations of each access network device and the aforementioned information.

[0047] In this embodiment of the disclosure, the request information is used to request bandwidth aggregation of multiple positioning reference signals in the frequency domain. The bandwidth-aggregated positioning reference signal can be equivalent to a positioning reference signal with a larger bandwidth. Here, the multiple positioning reference signals can be on different frequency resources or on different carriers.

[0048] The core network equipment includes, but is not limited to, Location Management Function (LMF).

[0049] Understandably, 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, limited by the maximum bandwidth of the carrier, it is impossible to effectively increase the bandwidth of a single positioning reference signal. Based on this, in this embodiment of the present disclosure, the terminal can send a request message to the network device to request the network device to aggregate the bandwidth of multiple positioning reference signals. Thus, during the positioning process, the terminal and / or the access network device can measure multiple positioning reference signals as an aggregated positioning signal with a larger bandwidth to achieve more accurate positioning of the terminal.

[0050] In some embodiments, the request information may further include: resource location information of multiple positioning reference signals for bandwidth aggregation; the resource location information is used to indicate the location of radio 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.

[0051] Frequency domain parameters are used to indicate the frequency domain location of the positioning reference signal; in one embodiment, frequency domain parameters may include, but are not limited to: frequency domain reference point, bandwidth, bandwidth part (BWP), sub-carrier spacing (SCS), starting physical resource block and / or resource unit offset, etc.

[0052] 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 symbols occupied, the number of transmissions and / or the transmission time interval, etc.

[0053] In some embodiments, the request information may also include information such as antenna port information that supports location reference signal aggregation.

[0054] In this embodiment of the disclosure, the terminal sends a request message to the network device to request 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 yield a frequency gain, thereby improving the positioning accuracy of the terminal and reducing the impact of inaccurate terminal positioning on information transmission performance.

[0055] In some embodiments, the request information includes: an on-demand location reference signal (PRS) request; or a sounding reference signal (SRS) request.

[0056] In this embodiment of the disclosure, the terminal sends an on-demand positioning reference signal (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 be bandwidth aggregated.

[0057] It should be noted that, in order to better meet the positioning needs of terminals, on-demand PRS is introduced in New Radio (NR) positioning, such as... Figure 3 As shown, the specific process of NR positioning based on on-demand PRS includes:

[0058] Step 0: The core network equipment obtains relevant information about the transmission and receiving points (TRPs) of multiple access network devices through the New Radio Positioning Protocol (NRPPa).

[0059] For on-demand PRS requests initiated by the terminal:

[0060] Step 1: The core network equipment provides the terminal with multiple predefined PRS configurations;

[0061] Step 2a: The terminal sends LPP request auxiliary data containing an on-demand PRS request to the core network equipment;

[0062] For on-demand PRS requests initiated by core network devices:

[0063] Step 2b: Core network equipment and terminals exchange LPP messages to determine the configuration of on-demand PRS;

[0064] Step 3: The core network equipment determines whether it is necessary to send a PRS or whether to change the transmission characteristics of the PRS.

[0065] Step 4: The core network device sends NRPPa PRS configuration requests to multiple access network devices;

[0066] Step 5: Multiple access network devices send NRPPa PRS configuration responses to the core network device;

[0067] Step 6: The core network equipment sends an LPP (Local Power Providing Assistance) data message containing an on-demand PRS response to the terminal.

[0068] In one embodiment, an on-demand PRS request includes at least one of the following: a PRS configuration requested by the terminal; a PRS configuration identifier requested by the terminal.

[0069] Understandably, a terminal can send an on-demand PRS request to the core network equipment according to its own needs, so that the core network equipment can provide PRS configuration to the terminal based on the terminal's on-demand PRS request; after obtaining the PRS configuration, the terminal receives the PRS based on the PRS configuration and completes the positioning measurement.

[0070] The terminal can 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 (SRS) 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.

[0071] Here, SRS is the uplink positioning reference signal, which is sent by the terminal to the access network device. Before sending SRS, the terminal can 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, so that the terminal can send SRS and complete the positioning measurement.

[0072] In this embodiment of the disclosure, the terminal sends on-demand PRS requests and / or SRS requests to the network device to request the network device to provide positioning reference signals on multiple different frequency domain resources that can be bandwidth aggregated, so that the positioning reference signal after bandwidth aggregation has a larger bandwidth and improves the positioning accuracy of the terminal.

[0073] In some embodiments, the request information includes at least one of the following:

[0074] Frequency information, indicating the frequency layer, carrier, frequency layer combination and / or carrier combination of bandwidth aggregation;

[0075] Priority information, indicating the priority of the corresponding frequency layer combination and / or carrier combination;

[0076] The first identifier ID includes the configuration ID, resource set ID, and / or resource ID associated with the location reference signal for the requested bandwidth aggregation;

[0077] The second identifier ID includes a predefined positioning reference signal configuration, wherein the predefined positioning reference signal configuration is a positioning reference signal configuration with bandwidth aggregation;

[0078] Access device indication, indicating the access device that performs bandwidth aggregation on the positioning reference signal.

[0079] In this embodiment of the disclosure, the request information may include frequency information of multiple positioning reference signals for request bandwidth aggregation.

[0080] Here, frequency information is used to indicate the frequency layer, carrier, frequency layer combination, and / or carrier combination of the positioning reference signal to be aggregated. In summary, frequency information can identify the frequency layer of the PRS and / or the carrier of the SRS for bandwidth aggregation.

[0081] It should be noted that frequency domain resources on frequency layers or carriers are a collection of frequency domain resources used for transmitting positioning reference signals. The terminal sends frequency information to the network device to indicate the location of the frequency domain resources for the positioning reference signal for which bandwidth aggregation is requested.

[0082] In one embodiment, the frequency information may be carried by a bitmap, where each indicator bit in the bitmap corresponds to a 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; the indicator bit is used to indicate that the terminal requests bandwidth aggregation for that frequency layer or carrier.

[0083] For example, an indicator bit in the bit diagram is 1 to indicate that the terminal requests bandwidth aggregation on that frequency layer or carrier; an indicator bit in the bit diagram is 0 to indicate that the terminal requests that bandwidth aggregation not be performed on that frequency layer or carrier.

[0084] In another embodiment, the frequency information may be carried by multiple bitmaps, each bitmap corresponding to a frequency layer combination or carrier combination.

[0085] It is understandable that the terminal sends frequency information to the network device based on one or more frequency layers or carriers it supports, so that the network device can know the frequency domain resource location of the positioning reference signal for which the terminal requests bandwidth aggregation.

[0086] In some embodiments, frequency information includes: a frequency band indication indicating frequency layering and / or carriers for bandwidth aggregation; and / or a frequency band combination indication indicating frequency layering combinations and / or carrier combinations capable of bandwidth aggregation.

[0087] In this embodiment of the disclosure, the frequency information may include: a frequency band indication and / or a frequency band combination indication. The frequency band indication is used to indicate multiple frequency layers and / or carriers of a bandwidth-aggregated positioning reference signal. The frequency band combination indication is used to indicate multiple frequency layer combinations and / or carrier combinations of a bandwidth-aggregated positioning reference signal; each frequency layer combination includes multiple frequency layers, and each carrier combination includes multiple carriers.

[0088] It is understandable that the terminal requests the network device to perform bandwidth aggregation on multiple frequency layers and / or carriers indicated by the frequency band indication by sending a frequency band indication; or requests 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 by sending a frequency band indication.

[0089] In one embodiment, the frequency information for 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.

[0090] In another embodiment, the frequency information for the SRS includes one of the following: the frequency band indication, indicating the carriers of the bandwidth-aggregated SRS; the frequency band combination indication, indicating the carrier combination of the SRS capable of bandwidth aggregation.

[0091] In some embodiments, the request information may further include priority information, which indicates the priority of the frequency layer combination and / or the carrier combination.

[0092] It is understandable that, for multiple frequency layer combinations and / or carrier combinations that can be bandwidth aggregated as indicated by frequency information, the frequency layer combination and / or carrier combination with the highest priority is determined according to 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.

[0093] In one embodiment, if the frequency information of the PRS includes the frequency band combination indication;

[0094] The request information for on-demand PRS also includes priority information, which indicates the priority of the frequency stratification combination of PRS.

[0095] In another embodiment, if the frequency information of the SRS includes the frequency band combination indication;

[0096] The SRS request information also includes priority information, indicating the priority of the carrier combination of the SRS.

[0097] In some embodiments, the request information may further include a first identifier ID, including a configuration ID, resource set ID, and / or resource ID associated with the location reference signal for the requested bandwidth aggregation.

[0098] Resource IDs can be used to uniquely identify location reference signal resources; a location reference signal resource is the smallest unit of configuration for a location reference signal, and one location reference signal resource corresponds to the transmission beam, carrier, or frequency layer of a location reference signal.

[0099] 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 that transmit 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.

[0100] A configuration ID is used to uniquely identify a positioning reference signal configuration. Different positioning reference signal configurations have different configuration IDs.

[0101] Network devices can send multiple predefined positioning reference signal configurations to terminals. It is understood that each positioning reference signal configuration may meet different positioning requirements. Terminals can select one positioning reference signal configuration from these configurations for positioning measurement based on their own positioning needs. It should be noted that different positioning reference signal configurations correspond to different transmission periods, bandwidths, and / or resources.

[0102] like Figure 4 As shown, this disclosure provides an information processing method, which is executed by a terminal device, and the method includes:

[0103] Step S201: Receive a first positioning reference signal configuration set sent by the network device; the first positioning reference signal configuration set includes a configuration ID, resource set ID, and / or resource ID associated with multiple positioning reference signals;

[0104] Step S202: Send request information containing a first identifier to the network device. The first identifier includes the configuration ID, resource set ID, and / or resource ID associated with the location reference signal for requesting bandwidth aggregation.

[0105] In this embodiment of the disclosure, the first positioning reference signal configuration set may include multiple positioning reference signal configurations predefined by the network device for the terminal; the positioning reference signal configuration includes a configuration ID, resource set ID and / or resource ID associated with the corresponding positioning reference signal.

[0106] The network device sends a first positioning reference signal configuration set to the terminal so that the terminal device can select the configuration ID, resource set ID, and / or resource ID associated with the positioning reference signal that meets the terminal device's requirements based on multiple positioning reference signal configurations within the first positioning reference signal configuration set. The terminal device then 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.

[0107] 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;

[0108] It should be noted that the second identifier ID can be used to indicate a predefined positioning reference signal configuration; it should also be noted that the network device predefines multiple positioning reference signal configurations for the terminal (i.e., the second positioning reference signal configuration set); and the second positioning reference signal configuration set includes at least one positioning reference signal configuration configured with bandwidth aggregation. Each positioning reference signal configuration within the second positioning reference signal configuration set has an identifier.

[0109] The terminal sends a request message carrying a second identifier ID to inform the network device of the location reference signal configuration requested by the terminal. If the terminal needs to perform bandwidth aggregation on the location reference signal, it can add the ID corresponding to the location reference signal configuration with bandwidth aggregation to the request message to request the network device to perform bandwidth aggregation on the location reference signal. If the terminal does not need to perform bandwidth aggregation on the location reference signal, it can add the ID corresponding to other location reference signal configurations to the request message.

[0110] In one embodiment, the location reference signal configuration may include at least one of the following: a partial bandwidth BWP identifier ID corresponding to the location reference signal resource; a frequency layer ID corresponding to the location reference signal resource; an access network device ID corresponding to the location reference signal resource; a TRP ID corresponding to the location reference signal resource; a location reference signal resource set ID; and a location reference signal resource ID.

[0111] like Figure 5 As shown, this disclosure provides an information processing method, which is executed by a terminal device, and the method includes:

[0112] Step S301: Receive a second positioning reference signal configuration set sent by the network device; the second positioning reference signal configuration set includes at least one positioning reference signal configuration configured with bandwidth aggregation.

[0113] Step S302: Send a request message containing a second identifier to the network device.

[0114] In this embodiment of the disclosure, the second positioning reference signal configuration set may include multiple positioning reference signal configurations predefined by the network device for the terminal; among the multiple positioning reference signal configurations, at least one positioning reference signal associated with the positioning reference signal configuration can be bandwidth aggregated.

[0115] The network device sends a second set of positioning reference signal configurations to the terminal so that the terminal device can select the positioning reference signal configuration associated with the positioning reference signal for positioning measurement based on multiple positioning reference signal configurations within the second set of positioning reference signal configurations.

[0116] If the second identifier carried by the terminal in the request information is the ID corresponding to the location reference signal configuration with bandwidth aggregation, it means that the terminal requests bandwidth aggregation of the location reference signal associated with the location reference signal configuration with bandwidth aggregation.

[0117] If the second identifier carried by the terminal in the request information is the ID corresponding to other positioning reference signal configurations within 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 bandwidth aggregation of the positioning reference signal corresponding to the positioning reference signal configuration.

[0118] In some embodiments, the request information may further include an access device indication, indicating the access device performing 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.

[0119] 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.

[0120] The terminal can send a request message containing an access device indication to the network device to inform the network device that the terminal requests bandwidth aggregation of the location reference signal associated with the access device corresponding to the access device indication.

[0121] In one embodiment, a terminal may send a request message to a network device; wherein the request message includes: frequency information, priority information, and / or access device indication.

[0122] Understandably, when the network device does not pre-configure positioning reference signals for the terminal, i.e., the network device does 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, so as to complete the bandwidth aggregation of multiple positioning reference signals.

[0123] It should be noted that the first identifier (or second identifier) ​​is the ID corresponding to one of the multiple positioning reference signal configurations selected by the terminal from the first positioning reference signal configuration set (or second positioning reference signal configuration set) sent by the network device. If the network device has not pre-configured positioning reference signals for the terminal, the request information sent by the terminal will not carry the first or second identifier. In this case, 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 positioning reference signals, requesting the network device to configure the required positioning reference signal resources; this achieves bandwidth aggregation of multiple positioning reference signals to meet the terminal's positioning needs.

[0124] This embodiment of the present disclosure carries frequency information, priority information, a first identifier ID, a second identifier ID, and / or access device indication in the request information, so that the network device can determine multiple positioning reference signal resources for bandwidth aggregation requested by the terminal based on the request information, thereby completing the configuration of multiple positioning reference signal resources and realizing bandwidth aggregation of multiple positioning reference signals; in the subsequent positioning process, the positioning reference signals after bandwidth aggregation are used for positioning measurement, thereby improving the positioning accuracy of the terminal.

[0125] In some embodiments, the frequency information includes at least one of the following: frequency band number; offset relative to a reference frequency value and / or bandwidth; identifier of the partial bandwidth (BWP).

[0126] In this embodiment of the disclosure, the frequency band number is used to indicate the frequency band of the positioning reference signal whose transmission bandwidth is aggregated. The offset relative to the reference frequency value can be the frequency offset between a reference frequency point and a measurement frequency point. In one embodiment, the reference frequency point can be reference point A or reference point B; the offset relative to the reference frequency value can be the frequency offset of point A or the frequency offset of point B.

[0127] The identifier of the BWP is used to indicate the BWP in which the frequency layer and / or carrier of the bandwidth aggregation is located, or to indicate the position of the frequency layer and / or carrier of the bandwidth aggregation on the BWP.

[0128] The terminal sends frequency information, including frequency band number, offset relative to reference frequency value, bandwidth and / or BWP identifier, to inform the network device that the terminal requests bandwidth aggregation of 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.

[0129] In some embodiments, any two positioning reference signals for bandwidth aggregation share at least one of the following parameters: resource period; resource set period; bandwidth; the amount of resources occupied by a positioning reference signal; and the repetition parameter of the positioning reference signal.

[0130] It should be noted that resource periodicity, resource set periodicity, resource bandwidth, the amount of resources occupied by a positioning reference signal, and resource repetition factor are configuration parameters of the positioning reference signal.

[0131] The prerequisite for bandwidth aggregation of two positioning reference signals is that the parameter values ​​of one or more configuration parameters among the resource period, resource set period, bandwidth, amount of resources occupied by the positioning reference signal, and repetition parameters of the positioning reference signal are all the same.

[0132] In this embodiment of the disclosure, the terminal sends a request message to the network device to request any two location reference signals for bandwidth aggregation to configure resources, so that the configuration parameters of the resources of any two location reference signals for bandwidth aggregation meet the prerequisites for bandwidth aggregation, so as to perform bandwidth aggregation on any two location reference signals requested by the terminal.

[0133] In some embodiments, the amount of resources occupied by a positioning reference signal includes: the number of time units occupied by a positioning reference signal; wherein, a time unit includes: a symbol, a micro-timeslot, or a timeslot; or, the amount of comb resources occupied by a positioning reference signal.

[0134] In this embodiment of the disclosure, the number of time units occupied by a positioning reference signal is used to describe the amount of time-domain resources occupied by the positioning reference signal; the time unit includes: a symbol, a micro-timeslot, or a time slot.

[0135] The positioning reference signal resource can have a comb structure, and the terminal can transmit the positioning reference signal on one of the comb structures; the number of comb resources (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, the number of comb resources occupied by the positioning reference signal is 4, which means that the positioning reference signal is carried on every 4th subcarrier of the positioning symbol.

[0136] In this embodiment of the disclosure, by sending a request message, the network device receives the request message and, based on the terminal's request, configures the resources of any two location reference signals for bandwidth aggregation so that the number of time units or comb resources occupied by any two location reference signals are the same. This ensures that the configuration parameters of the resources of any two location reference signals requesting bandwidth aggregation meet the prerequisites for bandwidth aggregation, so that bandwidth aggregation can be performed on any two location reference signals requested by the terminal.

[0137] In some embodiments, sending request information includes:

[0138] Send a request for a downlink location reference signal (PRS) to the core network equipment; or,

[0139] Send an uplink Sound Reference Signal (SRS) request message to the access network equipment.

[0140] In this embodiment of the disclosure, the positioning reference signal may include: an uplink detection reference signal SRS and a downlink on-demand positioning reference signal PRS.

[0141] Since SRS is sent by the terminal to the access network device, in order for the access network device to receive multiple bandwidth-aggregated SRS and perform positioning measurements based on the multiple bandwidth-aggregated SRS, the terminal can send an SRS request message to the access network device. This allows the access network device to configure SRS resources for the terminal based on the SRS request message, so that the terminal can send SRS and complete the positioning measurement.

[0142] Since the on-demand PRS is sent to the terminal by the access network equipment, in order for the terminal to receive multiple bandwidth-aggregated on-demand PRS and perform positioning measurements based on the multiple bandwidth-aggregated on-demand PRS, the terminal can send on-demand PRS request information to the core network equipment according to its own needs. The core network equipment can then provide 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.

[0143] In some embodiments, the request information is carried in a Long Term Evolution Positioning Protocol (LPP) Request for Assistance Data message sent to core network equipment.

[0144] In this embodiment of the disclosure, the terminal can add the request information of 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 can obtain the request information of on-demand PRS from the LPP request auxiliary data message.

[0145] It should be noted that LPP messages are signaling messages between terminals and core network equipment that exchange information such as positioning capabilities. Here, the terminal can carry on-demand PRS request information in the uplink LPP message.

[0146] In one embodiment, the LPP request auxiliary data message includes: one or more information fields for carrying the PRS request message. The information field may include multiple bits, which can be used to indicate frequency information, priority information, a first identifier ID, a second identifier ID, and / or access device indication of multiple location reference signals for bandwidth aggregation.

[0147] In this embodiment of the present disclosure, the terminal adds the request information for on-demand PRS to a dedicated signaling message. While the terminal transmits the dedicated signaling message to the core network device, it sends the request information for on-demand PRS to the core network device to request the core network device to perform bandwidth aggregation for PRS. In this way, no additional signaling or message is needed to carry the request information, which can reduce the signaling overhead.

[0148] In some embodiments, the request information sent to the access network device is carried in the Radio Resource Control (RRC) message; or in the Media Access Control (MAC) control unit (CE).

[0149] In this embodiment of the disclosure, the terminal can add the SRS request information to the RRC message, and then send the RRC message carrying the SRS request information to the access network device, so that the access network device can obtain the SRS request information from the RRC message.

[0150] It should be noted that RRC messages are signaling messages required for establishing, re-establishing, maintaining, and releasing RRC connections between the terminal and the access network equipment. Here, the terminal may carry SRS request information within the uplink RRC message.

[0151] Understandably, a terminal can carry different SRS request information by setting any one or more bits in the RRC message to different bit values.

[0152] The terminal can 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 can obtain the SRS request information from the MAC CE.

[0153] It should be noted that MAC CE is a signaling message required for the terminal and access network equipment to exchange MAC layer control information.

[0154] In this embodiment of the present disclosure, the terminal adds the SRS request information to a dedicated signaling message. While the terminal transmits the dedicated signaling message to the access network device, it sends the SRS request information to the access network device to request the access network device to perform bandwidth aggregation for SRS. In this way, no additional signaling or message is needed to carry the request information, which can reduce the signaling overhead.

[0155] like Figure 6 As shown, this disclosure provides an information processing method, which is executed by a network device, and the method includes:

[0156] Step S401: Receive request information, wherein the request information is used to perform bandwidth aggregation on the positioning reference signal.

[0157] In this embodiment of the disclosure, the network device receives request information sent by the terminal.

[0158] In this embodiment of the disclosure, the request information is used to request bandwidth aggregation of multiple positioning reference signals in the frequency domain. The bandwidth-aggregated positioning reference signal can be equivalent to a positioning reference signal with a larger bandwidth. Here, the multiple positioning reference signals can be on different frequency resources or on different carriers.

[0159] Understandably, according to the principle of positioning, the larger the bandwidth of the positioning reference signal used for positioning, the higher the positioning accuracy will be. However, limited by the maximum bandwidth of the carrier, it is impossible to effectively increase the bandwidth of a single positioning reference signal. Based on this, when the network device receives the request information, it aggregates the bandwidth of multiple positioning reference signals based on the terminal's request. Thus, during the positioning process, the terminal and / or access network device measure multiple positioning reference signals as an aggregated positioning signal with a larger bandwidth to achieve more accurate positioning of the terminal.

[0160] In some embodiments, the request information may further include: resource location information of multiple positioning reference signals for bandwidth aggregation; the resource location information is used to indicate the location of radio 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.

[0161] In some embodiments, the request information may also include information such as antenna port information that supports location reference signal aggregation.

[0162] In this embodiment of the present disclosure, the network device receives a request message sent by the terminal. Based on the request message, the network device performs bandwidth aggregation on positioning reference signals on multiple different frequency domain resources. Measuring the bandwidth-aggregated positioning reference signals yields the frequency gain, thereby improving the positioning accuracy of the terminal and reducing the impact of inaccurate terminal positioning on information transmission performance.

[0163] In some embodiments, the request information includes: an on-demand location reference signal (PRS) request; or a sounding reference signal (SRS) request.

[0164] In this embodiment of the disclosure, the network device can receive an on-demand Positioning Reference Signal (PRS) request sent by a terminal, and perform bandwidth aggregation on multiple downlink PRS based on the terminal's on-demand PRS request. Here, the network device can be a core network device.

[0165] In one embodiment, an on-demand PRS request includes at least one of the following: a PRS configuration requested by the terminal; a PRS configuration identifier requested by the terminal.

[0166] After receiving an on-demand PRS request, the core network equipment provides the PRS configuration to the terminal according to the terminal's on-demand PRS request; after obtaining the PRS configuration, the terminal receives the PRS based on the PRS configuration and completes the positioning measurement.

[0167] The network device receives a Sound Reference Signal (SRS) request sent by a terminal, and performs bandwidth aggregation on multiple uplink SRS requests based on the terminal's SRS request. Here, the network device can be an access network device.

[0168] In one embodiment, an 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.

[0169] Here, the access network device receives an SRS request and configures SRS resources for the terminal based on the SRS configuration or SRS configuration identifier in the terminal's SRS request, so that the terminal can send SRS and complete the positioning measurement.

[0170] In this embodiment of the disclosure, the network device receives on-demand PRS requests and / or SRS requests, and based on the on-demand PRS requests and / or SRS requests from the terminal, performs bandwidth aggregation on positioning reference signals on multiple different frequency domain resources, so that the bandwidth-aggregated positioning reference signals have a larger bandwidth and improve the positioning accuracy of the terminal.

[0171] In some embodiments, the request information includes at least one of the following:

[0172] Frequency information, indicating the frequency layer, carrier, frequency layer combination and / or carrier combination of bandwidth aggregation;

[0173] Priority information, indicating the priority of the corresponding frequency layer combination and / or carrier combination;

[0174] The first identifier ID includes the configuration ID, resource set ID, and / or resource ID associated with the location reference signal for the requested bandwidth aggregation;

[0175] The second identifier ID includes a predefined positioning reference signal configuration, wherein the predefined positioning reference signal configuration is a positioning reference signal configuration with bandwidth aggregation;

[0176] Access device indication, indicating the access device that performs bandwidth aggregation on the positioning reference signal.

[0177] In this embodiment of the disclosure, the request information may include frequency information of multiple positioning reference signals for request bandwidth aggregation.

[0178] Here, frequency information is used to indicate the frequency layer, carrier, frequency layer combination, and / or carrier combination of the positioning reference signal to be aggregated. In summary, frequency information can identify the frequency layer of the PRS and / or the carrier of the SRS for bandwidth aggregation.

[0179] It should be noted that frequency domain resources on frequency layers or carriers are a collection of frequency domain resources used for transmitting positioning reference signals. Network devices can determine the location of the frequency domain resources for the positioning reference signals for which the terminal requests bandwidth aggregation based on the frequency information sent by the terminal.

[0180] In one embodiment, the frequency information may be carried by a bitmap, where each indicator bit in the bitmap corresponds to a 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; the indicator bit is used to indicate that the terminal requests bandwidth aggregation for that frequency layer or carrier. For example, an indicator bit in the bitmap being 1 indicates that the terminal requests bandwidth aggregation for that frequency layer or carrier; an indicator bit in the bitmap being 0 indicates that the terminal requests no bandwidth aggregation for that frequency layer or carrier.

[0181] 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 it supports, so that the network device can know the frequency domain resource location of the positioning reference signal for which the terminal requests bandwidth aggregation.

[0182] In some embodiments, frequency information includes: a frequency band indication indicating frequency layering and / or carriers for bandwidth aggregation; and / or a frequency band combination indication indicating frequency layering combinations and / or carrier combinations capable of bandwidth aggregation.

[0183] In this embodiment of the disclosure, the frequency information may include: a frequency band indication and / or a frequency band combination indication. The frequency band indication is used to indicate multiple frequency layers and / or carriers of a bandwidth-aggregated positioning reference signal. The frequency band combination indication is used to indicate multiple frequency layer combinations and / or carrier combinations of a bandwidth-aggregated positioning reference signal; each frequency layer combination includes multiple frequency layers, and each carrier combination includes multiple carriers.

[0184] Understandably, the network device receives a frequency band indication and, based on the frequency band indication, determines multiple frequency layers and / or carriers for the bandwidth aggregation requested by the terminal. The network device also receives a frequency band combination indication and, based on the frequency band combination indication, determines multiple frequency layer combinations and / or carrier combinations for the bandwidth aggregation requested by the terminal.

[0185] In one embodiment, the frequency information for 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.

[0186] In another embodiment, the frequency information for the SRS includes one of the following: the frequency band indication, indicating the carriers of the bandwidth-aggregated SRS; the frequency band combination indication, indicating the carrier combination of the SRS capable of bandwidth aggregation.

[0187] In some embodiments, the request information may further include priority information, which indicates the priority of the corresponding frequency layer combination and / or carrier combination. It is understood 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. Then, bandwidth aggregation is performed on the multiple frequency layers within the frequency layer combination, and / or bandwidth aggregation is performed on the multiple carriers within the carrier combination.

[0188] In one embodiment, if the frequency information of the PRS includes the frequency band combination indication;

[0189] The request information for PRS also includes priority information, indicating the priority of the frequency stratification combination of PRS.

[0190] In another embodiment, if the frequency information of the SRS includes the frequency band combination indication;

[0191] The SRS request information also includes priority information, indicating the priority of the carrier combination of the SRS.

[0192] In some embodiments, the request information may further include a first identifier ID, including a configuration ID, resource set ID, and / or resource ID associated with the location reference signal for the requested bandwidth aggregation.

[0193] Resource IDs can be used to uniquely identify location reference signal resources; a location reference signal resource is the smallest unit of configuration for a location reference signal, and one location reference signal resource corresponds to the transmission beam, carrier, or frequency layer of a location reference signal.

[0194] 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 that transmit 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.

[0195] A configuration ID is used to uniquely identify a positioning reference signal configuration. Different positioning reference signal configurations have different configuration IDs.

[0196] Network devices can send multiple predefined positioning reference signal configurations to terminals; it is understood that each positioning reference signal configuration may meet different positioning requirements; the terminal can select one positioning reference signal configuration from the multiple positioning reference signal configurations for positioning measurement based on its own positioning requirements.

[0197] It should be noted that different positioning reference signal configurations correspond to different transmission periods, transmission bandwidths, and / or transmission resources for the positioning reference signals.

[0198] 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;

[0199] It should be noted that the second identifier ID can be used to indicate a predefined positioning reference signal configuration; it should also be noted that the network device predefines multiple positioning reference signal configurations for the terminal (i.e., the second positioning reference signal configuration set); and the second positioning reference signal configuration set includes at least one positioning reference signal configuration configured with bandwidth aggregation. Each positioning reference signal configuration within the second positioning reference signal configuration set has an identifier.

[0200] It is understandable that if the second identifier ID in the request information is the ID corresponding to the location reference signal configuration with bandwidth aggregation, it means that the terminal requests bandwidth aggregation of the location reference signal; if the second identifier ID in the request information is the ID corresponding to other location reference signal configurations, it means that the terminal does not request bandwidth aggregation of the location reference signal.

[0201] In one embodiment, the location reference signal configuration may include at least one of the following: a bandwidth part (BWP) identifier ID corresponding to the location reference signal resource; a frequency layer ID corresponding to the location reference signal resource; an access network device ID corresponding to the location reference signal resource; a TRP ID corresponding to the location reference signal resource; a location reference signal resource set ID; and a location reference signal resource ID.

[0202] In some embodiments, the request information may further include an access device indication, indicating the access device performing 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.

[0203] 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.

[0204] When a network device receives a request message containing an access device indication, it performs bandwidth aggregation on the location reference signal associated with the access device requested by the terminal, based on the access device indication.

[0205] This embodiment of the present disclosure carries frequency information, priority information, a first identifier ID, a second identifier ID, and / or access device indication in the request information, so that the network device can determine multiple positioning reference signal resources for bandwidth aggregation requested by the terminal based on the request information, thereby completing the configuration of multiple positioning reference signal resources and realizing bandwidth aggregation of multiple positioning reference signals; in the subsequent positioning process, the positioning reference signals after bandwidth aggregation are used for positioning measurement, thereby improving the positioning accuracy of the terminal.

[0206] In some embodiments, the frequency information includes at least one of the following: frequency band number; offset relative to a reference frequency value and / or bandwidth; identifier of the partial bandwidth (BWP).

[0207] In this embodiment of the disclosure, the frequency band number is used to indicate the frequency band of the positioning reference signal whose transmission bandwidth is aggregated. The offset relative to the reference frequency value can be the frequency offset between a reference frequency point and a measurement frequency point. In one embodiment, the reference frequency point can be reference point A or reference point B; the offset relative to the reference frequency value can be the frequency offset of point A or the frequency offset of point B.

[0208] The identifier of the BWP is used to indicate the BWP in which the frequency layer and / or carrier of the bandwidth aggregation is located, or to indicate the position of the frequency layer and / or carrier of the bandwidth aggregation on the BWP.

[0209] The terminal sends frequency information, including frequency band number, offset relative to reference frequency value, bandwidth and / or BWP identifier, to inform the network device that the terminal requests bandwidth aggregation of 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.

[0210] In some embodiments, the method further includes:

[0211] Send a predefined first positioning reference signal configuration set; the first positioning reference signal configuration set includes multiple configuration IDs, resource set IDs, and / or resource IDs associated with the positioning reference signals; or,

[0212] Send a predefined second set of positioning reference signal configurations; wherein the second set of positioning reference signal configurations includes at least one positioning reference signal configuration configured with bandwidth aggregation.

[0213] It should be noted that the first positioning reference signal configuration set may include multiple sets of positioning reference signal configurations predefined by the network device for the terminal; the positioning reference signal configuration includes the configuration ID, resource set ID and / or resource ID associated with the corresponding positioning reference signal.

[0214] The network device sends a first positioning reference signal configuration set to the terminal so that the terminal device can select 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 within the first positioning reference signal configuration set. The terminal device then carries the configuration ID, resource set ID, and / or resource ID associated with the positioning reference signal in a request message and sends the request message 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.

[0215] The second set of positioning reference signal configurations may include multiple positioning reference signal configurations predefined by the network device for the terminal; and at least one of the multiple positioning reference signal configurations is associated with a positioning reference signal that can be bandwidth aggregated.

[0216] The network device sends a second set of positioning reference signal configurations to the terminal so that the terminal device can select the positioning reference signal configuration associated with the positioning reference signal for positioning measurement based on multiple positioning reference signal configurations within the second set of positioning reference signal configurations.

[0217] If the second identifier ID in the request information received by the network device is the ID corresponding to the location reference signal configuration with bandwidth aggregation, it means that the terminal requests bandwidth aggregation of the location reference signal associated with the location reference signal configuration with bandwidth aggregation.

[0218] If the second identifier ID in the request information received by the network device is the ID corresponding to another positioning reference signal configuration within the second positioning reference signal configuration set, it indicates that the terminal requests to use the positioning reference signal corresponding to that positioning reference signal configuration for positioning measurement, but does not request bandwidth aggregation of the positioning reference signal corresponding to that positioning reference signal configuration. Figure 7 As shown, this disclosure provides an information processing method, executed by a network device, the method comprising:

[0219] Step S501: Configure parameters for any two of the positioning reference signals used for bandwidth aggregation;

[0220] Wherein, 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; the amount of resources occupied by a positioning reference signal; and the repetition parameter of the positioning reference signal.

[0221] It should be noted that resource periodicity, resource set periodicity, resource bandwidth, the amount of resources occupied by a positioning reference signal, and resource repetition factor are configuration parameters of the positioning reference signal.

[0222] The prerequisite for bandwidth aggregation of two positioning reference signals is that the parameter values ​​of one or more configuration parameters among the resource period, resource set period, bandwidth, amount of resources occupied by the positioning reference signal, and repetition parameters of the positioning reference signal are all the same.

[0223] In this embodiment of the disclosure, the network device receives request information and, based on the request information, configures resources for any two positioning reference signals for which the terminal requests bandwidth aggregation, so 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, so as to perform bandwidth aggregation on any two positioning reference signals requested by the terminal.

[0224] In some embodiments, the amount of resources occupied by a positioning reference signal includes: the number of time units occupied by a positioning reference signal; wherein, a time unit includes: a symbol, a micro-timeslot, or a timeslot; or, the amount of comb resources occupied by a positioning reference signal.

[0225] In this embodiment of the disclosure, the number of time units occupied by a positioning reference signal is used to describe the amount of time-domain resources occupied by the positioning reference signal; the time unit includes: a symbol, a micro-timeslot, or a time slot.

[0226] The positioning reference signal resource can have a comb structure, and the terminal can transmit the positioning reference signal on one of the comb structures; the number of comb resources (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, the number of comb resources occupied by the positioning reference signal is 4, which means that the positioning reference signal is carried on every 4th subcarrier of the positioning symbol.

[0227] In this embodiment of the disclosure, based on the terminal's request information, the network device configures resources for any two location reference signals in bandwidth aggregation so that the number of time units or comb resources occupied by any two location reference signals are the same, thereby ensuring that the configuration parameters of the resources of any two location reference signals requesting bandwidth aggregation meet the prerequisites for bandwidth aggregation, so as to perform bandwidth aggregation on any two location reference signals requested by the terminal.

[0228] In some embodiments, the receiving request information includes:

[0229] Receive downlink on-demand positioning reference signal (PRS) request information; wherein, the network device is a core network device;

[0230] Receives request information from an uplink probe reference signal (SRS); wherein, the network device is an access network device.

[0231] In this embodiment of the disclosure, the positioning reference signal may include: an uplink detection reference signal SRS and a downlink on-demand positioning reference signal PRS.

[0232] Since SRS is sent by the terminal to the access network device, in order for the access network device to receive multiple bandwidth-aggregated SRS and perform positioning measurements based on the multiple bandwidth-aggregated SRS, the terminal can send an SRS request message to the access network device. This allows the access network device to configure SRS resources for the terminal based on the SRS request message, so that the terminal can send SRS and complete the positioning measurement.

[0233] Since the on-demand PRS is sent to the terminal by the access network equipment, in order for the terminal to receive multiple bandwidth-aggregated on-demand PRS and perform positioning measurements based on the multiple bandwidth-aggregated on-demand PRS, the terminal can send on-demand PRS request information to the core network equipment according to its own needs. The core network equipment can then provide 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.

[0234] In some embodiments, the request information for On-Demand PRS is carried in a Long Term Evolution (LTE) Positioning Protocol (LPP) Request Assistance Data Message.

[0235] In this embodiment of the disclosure, the terminal can add the request information of on-demand PRS to the LPP request auxiliary data message. After receiving the LPP request auxiliary data message sent by the terminal, the core network device obtains the request information of on-demand PRS from the LPP request auxiliary data message, so as to perform bandwidth aggregation on multiple PRS based on the terminal's request.

[0236] It should be noted that LPP messages are signaling messages between terminals and core network equipment that exchange information such as positioning capabilities. Here, the terminal can carry on-demand PRS request information in the uplink LPP message.

[0237] In one embodiment, the LPP request auxiliary data message includes: one or more information fields for carrying the PRS request message. The information field may include multiple bits, which can be used to indicate frequency information, priority information, a first identifier ID, a second identifier ID, and / or access device indication of multiple location reference signals for bandwidth aggregation.

[0238] In this embodiment of the disclosure, by adding the request information into a dedicated signaling message, while the terminal and the core network device are transmitting the dedicated signaling message, the request information for on-demand PRS is sent to the core network device to request the core network device to perform bandwidth aggregation for PRS. In this way, no additional signaling or message is needed to carry the request information, which can reduce the signaling overhead.

[0239] In some embodiments, the SRS request information is carried in a Radio Resource Control (RRC) message; or in the Media Access Control (MAC) control unit (CE).

[0240] In this embodiment of the disclosure, by adding the SRS request information to the RRC message, the access network device receives the RRC message and obtains the SRS request information from the RRC message, so as to perform bandwidth aggregation on multiple SRS based on the terminal's request.

[0241] It should be noted that RRC messages are signaling messages required for establishing, re-establishing, maintaining, and releasing RRC connections between the terminal and the access network equipment. Here, the terminal may carry SRS request information within the uplink RRC message.

[0242] Understandably, one or more bits in an RRC message can be set to different bit values ​​to carry different SRS request information.

[0243] By adding the SRS request information to the MAC CE, the access network device receives the MAC CE and retrieves the SRS request information from the MAC CE to perform bandwidth aggregation on multiple SRSs based on the terminal's request.

[0244] It should be noted that MAC CE is a signaling message required for the terminal and access network equipment to exchange MAC layer control information.

[0245] In this embodiment of the 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 are transmitting the dedicated signaling message, so as to request the access network device to perform bandwidth aggregation for SRS. In this way, no additional signaling or message is needed to carry the request information, which can reduce the signaling overhead.

[0246] In one embodiment, the terminal sends a request for a location reference signal to the network device.

[0247] The ways in which a terminal sends request information to a network device may include:

[0248] The terminal sends a downlink on-demand positioning reference signal (PRS) request to the core network equipment;

[0249] The terminal sends an uplink probe reference signal (SRS) request to the access network equipment.

[0250] For on-demand PRS request information, the terminal can carry the on-demand PRS request information in the LPP request auxiliary data message.

[0251] On-demand PRS requests can be used as the request information for on-demand PRS, and the on-demand PRS request can be carried using the LPP request auxiliary data message; alternatively, an information field can be added to the LPP request auxiliary data message to carry the request information for on-demand PRS.

[0252] For example, an on-demand PRS request can be defined as:

[0253]

[0254] It should be noted that NR-On-Demand-DL-PRS-Request-r17 is the on-demand PRS request; DL-PRS-StartTime-and-Duration-r17 are the start time and duration parameters for downlink PRS; NR-On-Demand-DL-PRS-Information-r17 are the on-demand downlink PRS information parameters; dl-prs-configuration-id-PrefList-r17 is the predefined list of downlink PRS configuration identifiers; and 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 follows:

[0256]

[0257]

[0258] It should be noted that dl-prs-start-time-r17 is the start time of the downlink PRS; dl-prs-duration-r17 is the duration of the downlink PRS.

[0259] For each frequency stratum of the PRS, it can be defined as:

[0260]

[0261] It should be noted that NR-On-Demand-DL-PRS-PerFreqLayer-r17 is the frequency layer configuration for on-demand downlink PRS; dl-prs-FrequencyRangeReq-r17 is the frequency range parameter for downlink PRS; dl-prs-ResourceSetPeriodicityReq is the resource set period of downlink PRS; dl-prs-ResourceBandwidthReq is the resource bandwidth of downlink PRS; dl-prs-ResourceRepetitionFactorReq-r17 is the resource repetition parameter for downlink PRS; dl-prs-NumSymbolsReq-r17 is the number of symbols in downlink PRS; dl-prs-CombSizeN-Req-r17 is the number of comb resources in downlink PRS; and dl-prs-QCL-InformationReq is the QCL parameter for downlink PRS.

[0262] As one embodiment, the request information may include: a bandwidth aggregation frequency layer request;

[0263] The bandwidth aggregation frequency layer request is used to request bandwidth aggregation for multiple frequency layers associated with PRS.

[0264] A bandwidth aggregation frequency layer request includes at least one of the following:

[0265] Frequency layer indication for bandwidth aggregation; for example, a frequency layer indication for bandwidth aggregation used to request frequency layers f1 and f2 for bandwidth aggregation.

[0266] Frequency layer combination indication for bandwidth aggregation; for example, frequency layer combination indication for bandwidth aggregation to request bandwidth aggregation for frequency layers f1 and f2, and bandwidth aggregation for frequency layers f1 and f3.

[0267] Priority information indicates the priority of each frequency layer combination. For example, the priority information indicates {f1,f2}>{f1,f3}>{f1,f2,f3}.

[0268] As one embodiment, the request information may further include: a TRP indication for requesting bandwidth aggregation of PRS resources across multiple frequency layers of the TRP.

[0269] As one embodiment, the request information may also include:

[0270] The PRS configuration ID requests bandwidth aggregation across multiple frequency layers for the PRS associated with the PRS configuration ID.

[0271] The PRS resource set ID requests bandwidth aggregation of the PRS associated with the PRS across multiple frequency layers.

[0272] The PRS resource ID requests bandwidth aggregation of the PRS associated with the PRS across multiple frequency layers.

[0273] This embodiment can be used in combination with the previous embodiment.

[0274] For example, the request information may include: a TRP indication and a PRS resource set identifier, used to request bandwidth aggregation of the PRS associated with the resource set identifier within the TRP across multiple frequency layers.

[0275] For example, the request information may include: a TRP indication and a PRS resource identifier, used to request bandwidth aggregation of the PRS associated with the resource identifier within the TRP across multiple frequency layers.

[0276] As one embodiment, the terminal may receive multiple predefined PRS configurations (i.e., PRS configuration sets) sent by the core network device, wherein the multiple PRS configurations include at least one PRS configuration configured with bandwidth aggregation; the request information may include: PRS configuration identifier, PRS resource set identifier and / or PRS resource identifier.

[0277] It is understandable that if the PRS configuration identifier, PRS resource set identifier, and / or PRS resource identifier in the request information are predefined PRS configurations with bandwidth aggregation or configuration parameters within the PRS configuration, it means that the terminal requests bandwidth aggregation of the PRS associated with the PRS configuration identifier, PRS resource set identifier, and / or PRS resource identifier across multiple frequency layers.

[0278] If the PRS configuration identifier, PRS resource set identifier, and / or PRS resource identifier in the request information are not predefined PRS configurations with bandwidth aggregation or configuration parameters within the PRS configuration, it means that the terminal has not requested bandwidth aggregation of the PRS associated with the PRS configuration identifier, PRS resource set identifier, and / or PRS resource identifier across multiple frequency layers.

[0279] For example, the on-demand downlink PRS configuration set can be defined as:

[0280]

[0281] It should be noted that NR-On-Demand-DL-PRS-Configurations-r17 is the on-demand downlink PRS configuration set; On-Demand-DL-PRS-Configuration-r17 is the on-demand downlink PRS configuration; DL-PRS-Configuration-ID-r17 is the on-demand downlink PRS configuration identifier; nr-DL-PRS-PositioningFrequencyLayer-r17 is the downlink PRS frequency layer; and nr-DL-PRS-Info-r17 is the downlink PRS information.

[0282] The terminal sends a request to the core network device to configure the PRS resources for the requested bandwidth aggregation so that one or more of the following parameters are the same for any two PRSs in the requested bandwidth aggregation: PRS resource set period; PRS resource bandwidth; PRS resource repetition parameter; number of PRS symbols; PRS comb resources.

[0283] For example, the terminal may carry the PRS resource set period in dl-prs-ResourceSetPeriodicityReq-r17, the PRS resource bandwidth in dl-prs-ResourceSetPeriodicityReq-r17, the PRS resource repetition parameter in dl-prs-ResourceRepetitionFactorReq-r17, the number of PRS symbols in dl-prs-NumSymbolsReq-r17, and the PRS comb resources in dl-prs-CombSizeN-Req-r17.

[0284] For SRS request information, the terminal can carry the SRS request information in an RRC message or a MAC CE.

[0285] An SRS request can be carried as an SRS request message, using an RRC message or a MAC CE.

[0286] Alternatively, a new information field can be added to the RRC message or MAC CE to carry the PRS request information.

[0287] As one embodiment, the request information may include: bandwidth aggregation carrier indication; bandwidth aggregation carrier combination indication; priority information.
