[0077] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers are used to indicate the same elements throughout the several figures. The embodiments described in the following exemplary embodiments are not meant to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0078] The present disclosure provides a positioning reference signal configuration method, which can be applied to Figure 1 The wireless communication system is shown in FIG. 1, and a terminal accesses a wireless access network through a wireless access network device such as a base station, and the wireless access network device and a core network device complete data backhaul and forward transmission to perform various communication services. Figure 1

[0079] ​It can be understood that the wireless communication system is a network providing wireless communication function. The wireless communication system can adopt different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), carrier sense multiple access / collision avoidance (CSMA / CA). According to different network capacity, rate, delay and other factors, the network can be divided into 2G (English: generation) network, 3G network, 4G network or future evolution network, such as 5G network, 5G network can also be called new radio network (New Radio, NR). For the convenience of description, the wireless communication network in the present disclosure will be referred to as network or system for short. The network in the present disclosure can include a radio access network (RAN) and a core network (CN). The network includes network devices, such as wireless network devices, core network devices, etc. The wireless network device can also be referred to as a base station. The network can provide network services for terminals through network devices. Different operators can provide different network services for terminals, and different operators can also be understood as corresponding to different operator networks. For example, in 5G NR, the wireless network device can be referred to as gNB.

[0080] A terminal, sometimes called a mobile station (MS), user equipment (UE), or mobile terminal (MT), is a device that provides voice and / or data connectivity to a user. For example, a terminal can be a handheld device with wireless connectivity, an in-vehicle device, etc. Currently, examples of terminals include: smartphones (Mobile Phones), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablets, wearable devices, or in-vehicle devices. In this embodiment, the terminal is referred to as a UE for illustrative purposes.

[0081] 5G R16 introduces various positioning technologies to locate the UE. For some of these technologies, the network needs to send the PRS configuration to the UE. The network can... Figure 2 and Figure 3 The communication process shown sends the PRS configuration to the UE. The process of configuring the PRS for the UE is described using the downlink time difference of arrival (DL-TDOA) as an example. Figure 2 This is an exemplary embodiment illustrating the interaction flowchart of PRS configuration between a wireless network device and a core network device. (See also...) Figure 2 As shown, the LMF sends a DL-TDOA request message to the gNB via the NR Positioning Protocol A (NRPPa). Upon receiving the request, the gNB sends a DL-TDOA response message to the LMF, which contains the base station's PRS configuration information. After receiving the PRS configuration information, the LMF can then... Figure 3 The process shown sends PRS configuration information to the UE. Figure 3 This diagram illustrates an interactive flowchart of a core network device configuring PRS configuration information for a terminal in an exemplary embodiment. (See also...) Figure 3 As shown, the LMF includes the base station's PRS configuration information in the LTE Positioning Protocol (LPP) message sent to the UE. Alternatively, the LMF provides a positioning system message to the gNB, and the gNB sends a positioning system message containing the PRS configuration information.

[0082] However, the PRS configuration procedure of R16 is for periodic PRS configuration, i.e., after the network sends the periodic PRS configuration to the UE, the UE can always determine the PRS according to the PRS configuration, and the network periodically sends the PRS configuration according to the PRS. R17 considers introducing aperiodic PRS and semi-persistent PRS. The current PRS configuration procedure for the UE cannot meet the requirements of configuring aperiodic PRS and semi-persistent PRS configuration. Therefore, the existing PRS configuration procedure needs to be enhanced.

[0083] The embodiments of the present disclosure provide a PRS configuration method, in which a core network device requests and indicates PRS configuration information to a wireless network device, the PRS configuration information including at least one of periodic PRS configuration, aperiodic PRS configuration and semi-persistent PRS configuration. The core network device and / or the wireless network device determine the PRS configuration information and configure the PRS configuration information to a terminal, so as to realize downlink positioning by using aperiodic positioning reference signal or semi-persistent positioning reference signal, improve positioning accuracy and reduce positioning time delay.

[0084] It can be understood that the PRS configuration involved in the embodiments of the present disclosure can be downlink positioning PRS. For the convenience of description, the request information in which the core network device requests PRS configuration information and indicates the type of PRS to the wireless network device is referred to as first request information. The first request information is used to request PRS configuration information and to indicate the type of PRS. The type of PRS includes at least one of periodic PRS, aperiodic PRS and semi-persistent PRS. The PRS configuration information configured by the core network device / or the wireless network device to the terminal based on the type of PRS indicated by the first request information is referred to as first PRS configuration information.

[0085] Figure 4 A PRS configuration method according to an exemplary embodiment is shown in a flowchart as shown in Figure 4 The PRS configuration method is used in a core network device, such as LMF, and includes the following steps.

[0086] In step S11, the first request information is sent to the wireless network device, the first request information is used to request PRS configuration information and to indicate the type of PRS, and the type of PRS includes at least one of periodic PRS, aperiodic PRS and semi-persistent PRS.

[0087] In an example, the first request information can be an NRPPa message, and the NRPPa message includes indication information used to indicate that at least one of the following PRS is requested:

[0088] • Periodic PRS

[0089] • Aperiodic PRS

[0090] • Semi-Persistent PRS

[0091] The core network can determine the type of PRS used for positioning according to the positioning requirement, and thus indicates in the first request information whether the requested PRS is periodic PRS, aperiodic PRS or semi-persistent PRS. Further, the PRS configuration information involved in the embodiments of the present disclosure can be downlink PRS configuration information used for downlink positioning of the terminal.

[0092] The wireless network device receives the first request information sent by the core network device, and sends response information, hereinafter referred to as first response information. The core network device receives the first response information sent by the wireless network device. The first response information includes the PRS configuration information configured by the wireless network device.

[0095] The first PRS configuration information is determined based on the type of PRS.

[0096] In some embodiments, the first PRS configuration information also needs to be the PRS configuration supported by the wireless network device. For example, the core network device requests aperiodic PRS, and the wireless network device supports aperiodic PRS. Then, the first response information sent by the wireless network device to the core network device includes aperiodic PRS configuration.

[0097] In an implementation, the core network device can send the first request information to the wireless network device to which the serving cell of the terminal belongs and the wireless network device to which the neighbor cell of the terminal belongs, to request configuration of the indicated PRS configuration information. For the convenience of description, the wireless network device to which the serving cell of the terminal belongs is referred to as the first wireless network device, and the wireless network device to which the neighbor cell of the terminal belongs is referred to as the second wireless network device. That is, the wireless network device includes the first wireless network device and the second wireless network device, wherein the first wireless network device is the wireless network device to which the serving cell of the terminal belongs, and the second wireless network device includes the wireless network device to which the neighbor cell of the terminal belongs.

[0098] ​In an embodiment, the second wireless network device comprises a wireless network device participating in terminal positioning, and the core network device further needs to send the first PRS configuration information corresponding to the wireless network device participating in terminal positioning to the first wireless network device.

[0100] In step S13, the first PRS configuration information corresponding to the wireless network device participating in terminal positioning is sent to the first wireless network device.

[0102] In an example, in the embodiment of the present disclosure, the core network device can send the first PRS configuration information in an LPP message.

[0103] In an embodiment, the first PRS configuration information comprises a periodic PRS configuration, and the terminal can periodically receive PRS signals based on the periodic PRS configuration in a traditional manner. In another embodiment, the first PRS configuration information comprises aperiodic PRS configuration information and / or semi-persistent PRS configuration information. The terminal needs to wait for an indication from the network to determine the PRS. In the embodiment of the present disclosure, the core network device can send first indication information to the wireless network device, and the first indication information is used to instruct the wireless network device to activate the aperiodic PRS configuration information and / or the semi-persistent PRS configuration information, i.e., the wireless network device starts to send PRS after receiving the first indication information.

[0104] In an example, in the embodiment of the present disclosure, the core network device can send the first indication information in an NRPPa message.

[0109] In an implementation manner, the wireless network device can send the activation instruction to the terminal based on downlink control information (DCI).

[0140] In step S31, the first PRS configuration information is received. The first PRS configuration information is determined based on the type of PRS.

[0141] In an example, the first PRS configuration information is PRS configuration information supported by the wireless network device.

[0142] In the example, the type of PRS is indicated by the first request information sent by the core network device, and includes at least one of the periodic PRS configuration information, the aperiodic PRS configuration information, and the semi-persistent PRS configuration information.

[0147] Figure 14 is a flowchart of a PRS configuration method according to an exemplary embodiment, the PRS configuration method being used in a terminal. As shown in Figure 14 The PRS configuration method further includes step S33.

[0148] In step S33, if the first PRS configuration information includes aperiodic PRS configuration information and / or semi-persistent PRS configuration information, it is confirmed that the second indication information is received, the second indication information being used to activate the aperiodic PRS configuration information and / or the semi-persistent PRS configuration information.

[0149] The PRS configuration method provided by the embodiments of the present disclosure enables the terminal to utilize aperiodic PRS or semi-persistent PRS when performing downlink positioning, thereby improving positioning accuracy and reducing positioning latency.

[0150] It can be understood that the PRS configuration method provided by the embodiments of the present disclosure can also be applied to the interaction process of the terminal, the wireless network device and the core network device. The methods performed by the terminal, the wireless network device and the core network device in the implementation process of the PRS configuration method can be referred to the related descriptions of the above embodiments.

[0151] The PRS configuration method related to the embodiments of the present disclosure will be described below in combination with actual applications. In the embodiments of the present disclosure, the core network device is taken as an LMF, the wireless network device is taken as a gNB, and the terminal is taken as a UE. The main process of the LMF, the gNB and the UE to implement the PRS configuration is as follows.

[0152] 1. The LMF sends an NRPPa message to the gNB, the NRPPa message including indication information used to indicate that the PRS type requested by the LMF to the gNB is at least one of periodic PRS configuration, aperiodic PRS configuration and semi-persistent PRS configuration.

[0153] 2. After receiving the above NRPPa message, the gNB determines to send PRS configuration information to the LMF according to the PRS type requested by the LMF in the above indication. For example, the PRS type requested by the LMF is aperiodic PRS, then the gNB sends aperiodic PRS configuration to the LMF.

[0154] 3.1. The LMF sends at least one PRS configuration of the periodic PRS configuration information, the aperiodic PRS configuration information and the semi-persistent PRS configuration information sent by the gNB to the UE through the LPP message.

[0155] Wherein, it can be understood that the PRS configuration information requested by the LMF and the configuration information sent by the gNB to the LMF are not coupled. For example, the LMF requests the periodic PRS configuration information from the gNB, but the gNB sends the aperiodic PRS configuration information to the LMF.

[0156] 3.2. The LMF sends the PRS configuration information of multiple gNBs participating in the positioning of the UE to the gNB receiving the NRPPa message.

[0157] Wherein, for the positioning of the UE, multiple TRPs need to participate, on the one hand, it can be multiple TRPs of one gNB, on the other hand, it can also be multiple TRPs of multiple gNBs. When the positioning of the UE needs multiple TRPs corresponding to multiple gNBs, the PRS configuration information of other gNBs is also sent to the gNB corresponding to the serving cell of the UE. If multiple TRPs of one gNB participate in the positioning of the UE, step 3.2 does not need to be performed.

[0158] 4. The gNB sends the PRS configuration information to the UE.

[0159] 5. If the UE receives the periodic PRS configuration, the UE receives the PRS according to the PRS configuration. If the UE receives the aperiodic PRS or the semi-persistent PRS, it needs to wait for the indication of the network to receive the PRS.

[0160] 6. If the LMF configures the UE with semi-static or aperiodic PRS, the LMF sends indication information to the gNB, which is used to instruct the gNB to activate semi-static or aperiodic PRS transmission.

[0161] Wherein, when the gNB receives the PRS configuration information of other gNBs, and / or the LMF instructs the gNB to activate the PRS transmission of other gNBs, the gNB sends indication information to other gNBs through the Xn interface, instructing other gNBs to activate semi-static or aperiodic PRS transmission.

[0162] Understandably, when multiple TRPs involved in UE positioning are multiple gNBs, the LMF needs to send indication information to multiple gNBs. Specifically, the LMF sends the indication information to the gNB to which the UE's serving cell belongs, and the gNB to which the UE's serving cell belongs then sends the indication information to the other gNBs.

[0163] 7. The gNB sends an activation command (DCI) to the UE. After receiving the activation command, the UE receives the PRS according to the received PRS configuration.

[0164] Figure 15 This is a flowchart illustrating a PRS configuration method according to an exemplary embodiment. The PRS configuration method is used in the interaction process between the LMF, gNB, and UE. See also... Figure 15 As shown, gNB1 is the base station corresponding to the UE's serving cell (typically, a base station contains multiple cells). gNB2 is the base station corresponding to the UE's neighboring cells, participating in the UE's positioning. Specifically, the LMF requests aperiodic PRS configuration from gNB1 via an NRPPa message. The LMF also requests aperiodic PRS configuration from gNB2 via an NRPPa message. gNB1 determines the aperiodic PRS configuration and sends it to the LMF via an NRPPa message. gNB2 determines the aperiodic PRS configuration and sends it to the LMF via an NRPPa message. The LMF sends the aperiodic PRS configuration to the UE via LPP; the aperiodic PRS configuration includes the PRS configurations of gNB1 and gNB2. The LMF sends an activation aperiodic PRS configuration to gNB1 via an NRPPa message, and gNB sends the aperiodic PRS. The LMF sends an activation aperiodic PRS configuration to gNB2 via an NRPPa message, and gNB sends the aperiodic PRS. gNB1 sends an activation aperiodic PRS indication to the UE via DCI, and the UE receives the PRS according to the configuration.

[0165] Understandable, Figure 15 The PRS configuration process shown can also be performed without the participation of the base station corresponding to the UE's neighboring cell, i.e. without the participation of gNB2. In this case, multiple TRPs corresponding to gNB1 can complete the location of the UE.

[0166] Figure 16 This is a flowchart illustrating a PRS configuration method according to an exemplary embodiment. The PRS configuration method is used in the interaction process between the LMF, gNB, and UE. See also... Figure 16As shown, gNB1 is the base station corresponding to the serving cell of the UE (usually one base station contains multiple cells). gNB2 is the base station corresponding to the neighboring cell of the UE, participating in the positioning of the UE. Among them, the LMF requests the gNB1 to configure the aperiodic PRS through the NRPPa message. The LMF requests the gNB2 to configure the aperiodic PRS through the NRPPa message. The gNB1 decides the aperiodic PRS configuration and sends the aperiodic PRS configuration to the LMF through the NRPPa message. The gNB2 decides the aperiodic PRS configuration and sends the aperiodic PRS configuration to the LMF through the NRPPa message. The LMF sends the aperiodic PRS configuration to the gNB1 through the NRPPa, which includes the PRS configuration of the gNB1 and the gNB2. The gNB1 sends the received aperiodic PRS configuration to the UE through the RRC message. The LMF sends the gNB1 to activate the aperiodic PRS configuration through the NRPPa message, and the gNB1 sends the aperiodic PRS. The gNB1 sends the gNB2 to activate the aperiodic PRS configuration through the Xn message, and the gNB2 sends the aperiodic PRS. The gNB1 sends the UE to activate the aperiodic PRS indication through the DCI, and the UE receives the PRS according to the activated PRS configuration.

[0167] It can be understood that, Figure 16 The PRS configuration process involved in the above embodiment can also be carried out without the participation of the base station corresponding to the neighboring cell of the UE, that is, without the participation of the gNB2, and the positioning of the UE can be completed by the multiple TRPs corresponding to the gNB1.

[0168] The PRS configuration method provided by the present disclosure enables the core network device and the wireless network device to configure the aperiodic PRS or the semi-persistent PRS, and the terminal can utilize the aperiodic PRS or the semi-persistent PRS when performing downlink positioning, thereby improving the positioning accuracy and reducing the positioning delay.
