[0002] In a communication system, various positioning technologies have been further introduced to implement positioning of a terminal. For downlink, positioning technologies that combine downlink and uplink positioning, such as downlink time difference of arrival (DL-TDOA), downlink angle of arrival (DL-AOA), multi-round trip time (multi-RTT), etc., the terminal needs to obtain the configuration of a positioning reference signal (PRS) so as to perform relevant measurements on the PRS, and then the UE can be positioned.

[0137] Here, the exemplary embodiments will be described in detail, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0138] The parameter configuration method provided by the embodiments of the present disclosure can be applied to Figure 1 the wireless communication system shown in Figure 1 As shown, the wireless communication system includes a terminal and a network device. Information is transmitted and received between the terminal and the network device through wireless resources.

[0139] It can be understood that Figure 1 the wireless communication system shown in Figure 1 is only for illustrative purposes. The wireless communication system may further include other network devices, such as a core network device, a wireless relay device, and a wireless backhaul device, etc., which are not drawn in

[0140] It can be further understood that the wireless communication system of the embodiments of the present disclosure is a network that provides wireless communication functions. 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 FDMA (SC-FDMA), Carrier Sense Multiple Access with Collision Avoidance. According to factors such as the capacity, rate, and delay of different networks, the network can be divided into 2G (English: generation) network, 3G network, 4G network, or future evolved network, such as 5G network, and the 5G network can also be referred to as the New Radio (NR). For the convenience of description, the wireless communication network is sometimes simply referred to as the network in the present disclosure.

[0141] Furthermore, the network device involved in the present disclosure can also be referred to as a wireless access network device. The wireless access network device can be: a base station, an evolved node B (eNB), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP), etc. It can also be a gNB in the NR system, or it can also be a component or a part of the device that constitutes the base station. When it is a vehicle-to-everything (V2X) communication system, the network device can also be a vehicle-mounted device. It should be understood that in the embodiments of the present disclosure, the specific technologies and specific device forms adopted by the network device are not limited.

[0142] Further, the terminal involved in the present disclosure, which may also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., is a device that provides voice and / or data connectivity to users. For example, the terminal may be a handheld device with wireless connection capabilities, a vehicle-mounted device, etc. Currently, some examples of terminals are: smartphones (Mobile Phone), pocket personal computers (PPC), palm computers, personal digital assistants (PDA), laptop computers, tablet computers, wearable devices, or vehicle-mounted devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device may also be a vehicle-mounted device. It should be understood that the present disclosure embodiments do not limit the specific technologies and specific device forms adopted by the terminal.

[0143] In a communication system, various positioning technologies are further introduced to achieve the positioning of the terminal. For downlink, for positioning technologies that combine downlink and uplink positioning, such as DL-TDOA, DL-AOA, multi-RTT and other positioning technologies, the terminal needs to obtain the PRS configuration before it can perform positioning on the UE. Exemplarily, Figure 2 is a schematic diagram showing a method for obtaining the PRS configuration in the present disclosure. As Figure 2 shown, the UE can obtain the PRS configuration through the following process:

[0144] The core network location management function (LMF) network element actively provides positioning assistance information to the UE. The LMF can provide assistance positioning information to the UE through the positioning protocol (LPP), where the assistance information includes the PRS configuration.

[0145] Or, in another implementation, Figure 3 is another schematic diagram showing a method for obtaining the PRS configuration in the present disclosure. As Figure 3 shown, the UE sends a positioning assistance information request to the LMF. After receiving the request from the UE, the LMF sends assistance information to the UE, where the assistance information includes the PRS configuration.

[0146] The following embodiments will be combined with Figure 3 Taking the DL-AOA / DL-TDOA positioning technology as an example, the implementation of UE positioning will be described. Figure 4 is yet another schematic diagram showing a method for obtaining the PRS configuration in the present disclosure. As Figure 4As shown, the LMF sends an LPP Request capabilities message to the UE to request the positioning capabilities of the UE. The UE can provide its positioning capabilities to the LMF and receive positioning assistance information and positioning information requests sent by the LMF. The UE receives the PRS according to the measurement interval configured by the network and measures the PRS. The UE provides the measurement results to the LMF. The positioning assistance information includes the PRS configuration.

[0147] It can be seen from the above embodiments that during the positioning of the UE using the downlink positioning technology, the LMF needs to provide positioning assistance information to the UE through the LPP message, and configure the terminal PRS configuration through the positioning assistance information. During this process, the end-to-end delay is about 50 ms. However, in the related art, for the IIOT scenario, it is further proposed that the end-to-end delay is about 10 ms. Therefore, it is necessary to further reduce the delay of the existing positioning technology to meet the positioning requirements.

[0148] Based on this, the present disclosure proposes that the PRS configuration can be pre-configured for the UE, and it is not necessary to send the PRS configuration information to the UE during the positioning of the UE, thus achieving the effect of reducing the positioning delay. The network device pre-configures the PRS configuration information for the UE. When the UE needs to use the PRS configuration information, the network device activates the PRS configuration information used by the UE. The UE determines to measure the PRS based on the activated PRS configuration information to complete the positioning of the UE and reduce the positioning delay. It can be understood that in the embodiments of the present disclosure, the PRS configuration information can also be referred to as the PRS configuration parameters.

[0149] Figure 5 is a flowchart of a parameter configuration method shown according to an exemplary embodiment. As Figure 5 shown, the parameter configuration method is used in a terminal and includes the following steps.

[0150] In step S11, a pre-configured set of positioning reference signal PRS configuration parameters is determined.

[0151] In the embodiments of the present disclosure, the UE determines a set of PRS configuration parameters and pre-configures the set of PRS configuration parameters, where the set of PRS configuration parameters includes at least one set of PRS configuration parameters. The UE can measure the PRS based on at least one set of PRS configuration parameters to determine the UE positioning information.

[0152] Among them, the set of PRS configuration parameters can be one of the following situations:

[0153] In one implementation, the set of PRS configuration parameters can include the PRS configuration parameters of the same radio network device, and the set of PRS configuration parameters includes at least one set of PRS configuration parameters.

[0154] In one embodiment, the set of PRS configuration parameters may include PRS configuration parameters of multiple different wireless network devices. The set of PRS configuration parameters includes at least one set of PRS configuration parameters, and each set of PRS configuration parameters corresponds to PRS configuration parameters of multiple different wireless network devices.

[0155] In step S12, determine the PRS configuration parameters for receiving PRS based on the set of PRS configuration parameters.

[0156] In the embodiments of the present disclosure, the UE may determine the PRS configuration according to a pre-configured set of PRS configuration parameters, where the PRS configuration determined based on the set of PRS configuration parameters is used to receive PRS. As described above, in one embodiment, if the set of PRS configuration parameters includes PRS configuration parameters of the same wireless network device, the UE determines at least one set of PRS configurations based on different sets of PRS configuration parameters. In one embodiment, if the set of PRS configuration parameters includes PRS configuration parameters of different wireless network devices, the UE may determine at least one set of PRS configurations based on the pre-configured set of PRS configuration parameters. Each set of determined PRS configuration parameters corresponds to PRS configuration parameters of multiple different wireless network devices, and then determines the PRS configuration parameters for receiving PRS.

[0157] In some embodiments of the present disclosure, the UE may determine the pre-configured set of PRS configuration parameters according to the received first indication message. Wherein, the first indication information is used to indicate the UE the pre-configured set of PRS configuration parameters.

[0158] In the embodiments of the present disclosure, the UE may receive the first indication message based on the random access message (message, MSG) 4 (message)\MSG 2 in the random access process between the UE and a wireless network device (such as a base station).

[0159] In the embodiments of the present disclosure, the UE may receive the first indication message through a Radio Resource Control (RRC) message.

[0160] In the embodiments of the present disclosure, the UE may receive the first indication message through Downlink Control Information DCI.

[0161] In the embodiments of the present disclosure, the UE may receive the first indication message through the LPP message sent by the LMF.

[0162] It can be understood that in response to receiving the LPP message, the UE determines the pre-configured set of PRS configuration parameters included in the LPP message, and determines to use the pre-configured set of PRS configuration parameters included in the LPP message by receiving the pre-configured set of PRS configuration parameters through the RRC message or MSG 2 / MSG 4.

[0163] In an embodiment of the present disclosure, the UE may receive a second indication message, where the second indication message is used to instruct the terminal to determine the parameters of the PRS configuration based on a set of PRS configuration parameters. The UE may determine the parameters of the PRS configuration used by the UE to receive the PRS according to the received second indication message.

[0164] In an embodiment of the present disclosure, the PRS configuration determined by the UE for receiving the PRS may be a subset of the set of preconfigured PRS configuration parameters of the UE. In an embodiment of the present disclosure, the determined PRS configuration used by the UE to receive the PRS is referred to as a subset of PRS configuration parameters, that is, the network preconfigures a set of PRS configuration parameters for the UE through the first indication information. The set of PRS configuration parameters includes at least one set of PRS configuration parameters. The network configures the configuration parameters of the PRS for the UE through the second indication information. The PRS configuration parameters configured for the UE through the second indication information are one set of PRS configuration parameters among multiple sets of PRS configuration parameters in the set of PRS configuration parameters. In an embodiment of the present disclosure, the second indication information includes at least one of the following:

[0165] A first indicator, indicating that the terminal activates the PRS configuration parameters;

[0166] A second indicator, indicating that the terminal receives the PRS.

[0167] Among them, the PRS configuration parameters indicating the activation of the UE are the subset of PRS configuration parameters; the first indicator and / or the second indicator may be symbols such as bit positions.

[0168] In one manner of an embodiment of the present disclosure, in response to the received second indication information only including the first indicator, the UE determines the activated PRS configuration parameters and / or the subset of PRS configuration parameters, and receives the PRS. Among them, the first indicator may also implicitly instruct the UE to receive the PRS according to the activated PRS configuration parameters and / or the subset of PRS configuration parameters.

[0169] In one manner, in response to the received second indication information only including the second indicator, the UE determines to receive the PRS based on the preconfigured set of PRS configuration parameters. In an embodiment of the present disclosure, if the received second indication message includes the second indicator, it is determined that the preconfigured set of PRS configuration parameters of the UE only includes one set of PRS configuration parameters.

[0170] In one manner, in response to the received second indication information including the first indicator and the second indicator, the UE determines the activated PRS configuration parameters and / or the subset of PRS configuration parameters, and determines to receive the PRS based on the second indicator.

[0171] In an embodiment of the present disclosure, the second indication message may be determined according to the RRC and / or MAC and / or DCI messages sent by the base station. Alternatively, the second indication message may be determined based on the LPP message sent by the LMF.

[0172] In an embodiment of the present disclosure, the UE measures the PRS based on the PRS configuration parameters. Further, the UE receives the PRS according to the determined PRS configuration, measures the received PRS, and determines the PRS measurement result. Wherein, the measurement result may include location information.

[0173] In an embodiment of the present disclosure, the UE may also send the PRS measurement result or location information to the core network device (such as the LMF) and / or the radio network device.

[0174] Based on the same / similar concept, an embodiment of the present disclosure also provides a parameter configuration method.

[0175] Figure 6 is a flowchart of a parameter configuration method shown according to an exemplary embodiment. As Figure 6 shown, the parameter configuration method is used in the core network device and includes the following steps.

[0176] In step S21, a set of positioning reference signal (PRS) configuration parameters is determined.

[0177] In an embodiment of the present disclosure, the core network device may be the LMF. The LMF determines at least one set of PRS configuration parameters and determines a set of PRS configuration parameters according to the determined at least one set of PRS configuration parameters.

[0178] In one implementation, the LMF may indicate to the radio network device to provide at least one set of PRS configuration parameters by sending an NR positioning protocol (NRPPa) message to the radio network device. Wherein, the radio network device may include one or more. The LMF determines a set of PRS configuration parameters according to the at least one set of PRS configuration parameters sent by the received one or more radio network devices.

[0179] In an embodiment of the present disclosure, the LMF sends a first indication message to the UE. Wherein, the first indication message is used to indicate the terminal to pre-configure a set of PRS configuration parameters.

[0180] The LMF determines a set of PRS configuration parameters and indicates to the terminal to pre-configure the set of PRS configuration parameters by sending a first indication message. Wherein, the first indication message is used to indicate the terminal to pre-configure a set of PRS configuration parameters.

[0181] In an embodiment of the present disclosure, the LMF may send a first indication message to the UE based on the LPP message.

[0182] In some embodiments of the present disclosure, the LMF determines PRS configuration parameters for instructing the UE to receive PRS. The LMF may send a second indication message to the UE to instruct the UE to determine the PRS configuration parameters based on a set of PRS configuration parameters. Among them, the PRS configuration parameters are a subset of the set of PRS configuration parameters.

[0189] In one way, only the second indicator is included in the second indication information sent by the LMF, and it is determined to instruct the UE to receive the PRS based on a preconfigured set of PRS configuration parameters. In an embodiment of the present disclosure, if the second indication message sent by the LMF includes the second indicator, it is determined that a set of PRS configuration parameters is included in the preconfigured set of PRS configuration parameters of the UE.

[0190] In one way, both the first indicator and the second indicator are included in the second indication information sent by the LMF, and it is determined that the PRS configuration parameters and / or the subset of PRS configuration parameters for instructing the UE to activate are based on the first indicator, and the UE is explicitly instructed to receive the PRS based on the second indicator.

For example, the third indication message sent by the LMF includes the set of PRS configuration parameters and an indicator for indicating that the radio network device pre-configures the set of PRS configuration parameters for the UE. The radio network device pre-configures the set of PRS configuration parameters for the UE according to the received third indication message.

[0194] In one implementation, the LMF may indicate to the radio network device to pre-configure a set of PRS configuration parameters for the UE in an implicit indication manner. For example, if the third indication message sent by the LMF includes the set of PRS configuration parameters, it may implicitly indicate that the radio network device pre-configures the set of PRS configuration parameters for the UE. The radio network device pre-configures the set of PRS configuration parameters for the UE according to the received third indication message.

The radio network device determines the PRS configuration parameters for indicating UE activation according to the received fourth indication message, and sends the PRS to the UE according to the indicator for indicating that the radio network device sends the PRS included in the fourth indication message.

[0200] In one implementation, the LMF may implicitly indicate to the radio network device to determine PRS configuration parameters based on a set of PRS configuration parameters. For example, if the fourth indication message sent by the LMF includes the PRS configuration parameters, it may implicitly indicate to the radio network device to determine the PRS configuration parameters based on the set of PRS configuration parameters and determine to send the PRS to the UE.

[0213] Figure 8 is a flowchart of a parameter configuration method shown according to an exemplary embodiment. As Figure 8 shown, the parameter configuration method is used in a wireless network device and includes the following steps.

[0214] In step S41, a second indication message is determined.

[0215] In an embodiment of the present disclosure, the second indication message is used to instruct the terminal to determine PRS configuration parameters based on a set of PRS configuration parameters. The wireless network device determines the PRS configuration parameters based on the set of PRS configuration parameters, and then determines the second indication message.

[0216] In step S42, the second indication message is sent.

[0218] RRC message;

[0219] MAC message;

The wireless network device may determine the preconfigured set of PRS configuration parameters for the terminal according to the third indication message, and then may determine the first indication message to be sent to the UE.

[0222] In an embodiment of the present disclosure, the wireless network device may receive the third indication information sent by the LMF through an NRPPa message.

[0223] Among them, in one implementation manner, the LMF may indicate to the wireless network device to preconfigure a set of PRS configuration parameters for the UE in an explicit indication manner. For example, the third indication message sent by the LMF includes a set of PRS configuration parameters and an indicator for indicating that the wireless network device preconfigures the set of PRS configuration parameters for the UE, and the wireless network device preconfigures the set of PRS configuration parameters for the UE according to the received third indication message.

[0224] In one implementation, the LMF may implicitly indicate to the radio network device to pre-configure a set of PRS configuration parameters for the UE. For example, if the set of PRS configuration parameters is included in the third indication message sent by the LMF, it may implicitly indicate to the radio network device to pre-configure the set of PRS configuration parameters for the UE, and the radio network device pre-configures the set of PRS configuration parameters for the UE according to the received third indication message.

The radio network device may send PRS according to the determined PRS configuration parameters. The PRS configuration parameters are a subset of the set of PRS configuration parameters, and further, a second indication message sent to the UE may be determined.

[0226] In the embodiments of the present disclosure, the radio network device may receive the fourth indication information sent by the LMF through an NRPPa message.

[0227] In one implementation, the LMF may explicitly indicate to the radio network device to determine PRS configuration parameters based on a set of PRS configuration parameters. For example, the fourth indication message sent by the LMF includes PRS configuration parameters and an indicator for indicating that the radio network device sends PRS. The radio network device determines the PRS configuration parameters for indicating UE activation according to the received fourth indication message, and sends PRS to the UE according to the indicator for indicating that the radio network device sends PRS included in the fourth indication message.

[0228] In one implementation, the LMF may implicitly indicate to the radio network device to determine PRS configuration parameters based on a set of PRS configuration parameters. For example, if the PRS configuration parameters are included in the fourth indication message sent by the LMF, it may implicitly indicate that the radio network device determines PRS configuration parameters based on the set of PRS configuration parameters and determines to send PRS to the UE.

[0229] In the embodiments of the present disclosure, the second indication message includes at least one of the following:

[0234] In one aspect, the second indication information sent by the wireless network device only includes a second indicator, and it is determined to instruct the UE to receive the PRS based on a preconfigured set of PRS configuration parameters. In the embodiments of the present disclosure, if the second indication message sent by the wireless network device includes the second indicator, it is determined that a set of PRS configuration parameters is included in the preconfigured set of PRS configuration parameters of the UE.

[0235] In one aspect, the second indication information sent by the wireless network device includes a first indicator and a second indicator, and it is determined that the PRS configuration parameters and / or a subset of the PRS configuration parameters that the UE needs to activate are indicated based on the first indicator, and the UE is explicitly instructed to receive the PRS based on the second indicator.

[0236] In the embodiments of the present disclosure, the second indication message may be sent to the UE through an RRC and / or MAC and / or DCI message.

[0237] In the embodiments of the present disclosure, the wireless network device may receive the PRS measurement result reported by the UE.

[0238] In the embodiments of the present disclosure, after receiving the PRS measurement result reported by the UE, the wireless network device may send the PRS measurement result to a core network device (such as an LMF).

[0239] In the following embodiments, the serving cell of the UE is taken as the first base station and the neighboring cell is taken as the second base station as an example to illustrate the parameter configuration method provided by the present disclosure.

[0240] Figure 9 It is a schematic diagram of indication information shown according to an exemplary embodiment.

The first base station and / or the second base station are instructed through the NRPPa message to respectively provide at least one set of PRS configuration parameters to the LMF.

[0241] In response to receiving the NRPPa message, the first base station and / or the second base station determine at least one set of PRS configuration parameters, and send the determined at least one set of PRS configuration parameters to the LMF through the NRPPa message.

[0242] The LMF determines a set of PRS configuration parameters based on at least one set of received PRS configuration parameters, and sends a third indication message (i.e., 3-1 PRS pre-configuration indication information) indicating the pre-configured PRS configuration parameter set for the UE to the serving cell of the UE (i.e., the first base station). The first base station may send a first indication message based on the RRC message to indicate the UE to pre-configure the PRS configuration parameter set. Alternatively, the LMF sends the first indication message to the UE through the LPP message to indicate the UE to pre-configure the PRS configuration parameter set.

Among them, the fourth indication information includes a first indicator for indicating the activation of a subset of the PRS configuration parameters and / or a second indicator for indicating the terminal to receive the PRS.

[0245] The first base station sends a location information request to the UE through the RRC message. The location information request includes a second indication information, indicating the UE to activate the PRS configuration for receiving the PRS. Among them, the second indication information includes a first indicator for indicating the activation of a subset of the PRS configuration parameters and / or a second indicator for indicating the terminal to receive the PRS.

[0246] After receiving the second indication information sent by the first base station, the UE receives the PRS, completes the PRS measurement, and determines the PRS measurement result. The UE reports the PRS measurement result to the first base station, or the UE reports the PRS measurement result to the LMF through the LPP message.

As Figure 11As shown, in the embodiments of the present disclosure, the LMF may send a location information request to the UE through an LPP message (e.g., LPP information request).

The fourth indication information is used to instruct the terminal to activate the PRS configuration parameters for receiving the PRS. The fourth indication information includes a first indicator for activating a subset of the PRS configuration parameters and / or a second indicator for instructing the terminal to receive the PRS.

[0249] After receiving the second indication information sent by the LMF or the second indication message sent by the first base station, the UE determines to receive the PRS, completes the PRS measurement, and determines the accurate PRS measurement result. The UE reports the PRS measurement result to the LMF through an LPP message.
