Description

[0001] The present invention relates to the field of wireless communication technology, and in particular to a parameter setting method, a parameter setting device, and a storage medium. Background Technology

[0002] In a communication system, positioning for a terminal is implemented by introducing multiple positioning technologies. For positioning technologies that combine downlink, downlink, and uplink positioning, such as Downlink Time Difference Of Arrival (DL-TDOA), Downlink Angle Of Arrival (DL-AOA), and Multi-Round Trip Time (multi-RTT), the terminal must obtain a configuration of a positioning reference signal (PRS) and perform relevant measurements on the PRS in order to position the UE.

[0003] For application scenarios of the Industrial Internet of Things (IIOT), there is a demand for end-to-end latency reduction; therefore, the latency of conventional positioning technologies must be further reduced to satisfy business requirements.

[0121] Exemplary embodiments are described in detail below. Such embodiments are illustrated in the drawings, and where the following description relates to the drawings, the same numbers in different drawings indicate the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not representative of all embodiments consistent with the present invention. On the contrary, they are merely examples of apparatuses and methods consistent with some aspects of the present invention described in detail in the appended claims.

[0122] The parameter setting method provided in an embodiment of the present invention can be applied to a wireless communication system illustrated in FIG. 1. As illustrated in FIG. 1, the wireless communication system includes a terminal and a network device. Transmission and reception of information are performed between the terminal and the network device via wireless resources.

[0123] It should be understood that the wireless communication system illustrated in FIG. 1 is for illustrative purposes only, and the wireless communication system may further include other network devices. For example, it may further include core network devices, wireless relay devices, and wireless return devices, which are not illustrated in FIG. 1. The embodiments of the present invention are not limited to the number of network devices and terminals included in the wireless communication system.

[0124] It is further understood that the wireless communication system of the embodiment of the present invention is a network that provides wireless communication functions. The wireless communication system may use different communication technologies. For example, it may use 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), and Carrier Sense Multiple Access with Collision Avoidance. Depending on factors such as capacity, speed, and latency of the different networks, the network may be divided into a 2G network, a 3G network, a 4G network, or a future evolution network. For example, it may be divided into a 5G network, and the 5G network may be a New Radio (NR). For convenience of explanation, the present invention may, in some cases, abbreviate a wireless communication network as a network.

[0125] Furthermore, the network device mentioned in the present invention may be a wireless access network device. Such wireless access network device may be a base station, an evolved node B (base station), a femtocell, an access point (AP) of a wireless fidelity (WIFI) system, a wireless relay node, a wireless return node, a transmission point (TP), or a transmission and reception point (TRP), etc., or it may be a gNB of an NR system, or it may be an assembly or part of a device constituting a base station. In the case of a Vehicle-to-Everything (V2X) communication system, the network device may be a vehicle-mounted device. It should be understood that the specific technology and specific device form used by the network device in the embodiments of the present invention are not limited.

[0126] Furthermore, the terminal mentioned in the present invention may be referred to as a terminal device, User Equipment (UE), Mobile Station (MS), Mobile Terminal (MT), etc., and is a device that provides voice and / or data connectivity to a user. For example, the terminal may be a portable device equipped with wireless connectivity functions, a vehicle-mounted device, etc. Currently, examples of terminals include smartphones (Mobile Phones), Pocket Personal Computers (PPCs), Palmtop Computers, Personal Digital Assistants (PDAs), laptops, Tablet PCs, wearable devices, or vehicle-mounted devices. Additionally, in the case of a Vehicle-to-Everything (V2X) communication system, the terminal device may be a vehicle-mounted device. It should be understood that the embodiments of the present invention are not limited to specific technologies or specific device forms used by the terminal.

[0127] In a communication system, positioning for a terminal is implemented by introducing multiple positioning technologies. For positioning technologies that combine downlink, downlink, and uplink positioning, such as DL-TDOA, DL-AOA, and multi-RTT, the terminal must acquire all PRS settings to be positioned for the UE. For example, FIG. 2 is a schematic diagram of acquiring PRS settings illustrated in the present invention. As shown in FIG. 2, the UE can acquire PRS settings through the following process.

[0128] Network elements of the core network positioning management function (LMF) proactively provide auxiliary positioning information to the UE, and the LMF provides auxiliary positioning information to the UE via the positioning protocol (LPP), wherein the auxiliary information includes PRS settings.

[0129] Alternatively, in another method of execution, FIG. 3 is a schematic diagram for obtaining other PRS settings illustrated in the present invention. As illustrated in FIG. 3, the UE transmits a positioning auxiliary information request to the LMF, and after receiving the UE's request, the LMF transmits auxiliary information to the UE, wherein the auxiliary information includes PRS settings.

[0130] The following embodiment describes the implementation of UE positioning in combination with FIG. 3, using DL-AOA / DL-TDOA positioning technology as an example. FIG. 4 is a schematic diagram for obtaining another PRS setting illustrated in the present invention. As illustrated in FIG. 4, the LMF requests the UE's positioning capabilities by transmitting an LPP Request capabilities message to the UE, and the UE provides the positioning to the LMF and can receive positioning auxiliary information and a positioning information request transmitted from the LMF. The UE receives the PRS and measures the PRS according to the measurement interval of the network setting. The UE provides the measurement results to the LMF. Here, the positioning auxiliary information includes the PRS setting.

[0131] As can be seen from the above embodiment, in the process of positioning a UE using downlink positioning technology, the LMF must provide positioning assistance information to the UE via an LPP message, set the terminal's PRS settings using the positioning assistance information, and in this process, the end-to-end delay is approximately 50ms. However, in related technology, a requirement was submitted for an end-to-end delay of approximately 10ms for an IIOT scenario. Therefore, the positioning requirement must be satisfied by reducing the delay of the conventional positioning technology.

[0132] Based on this, the present invention provides for pre-setting PRS settings in a UE, and since it is not necessary to transmit PRS setting information to the UE during the positioning process for the UE, it achieves the effect of reducing positioning delay. A network device pre-sets PRS setting information in a UE, and when the UE needs to use the PRS setting information, the network device activates the PRS setting information used by the UE, and the UE measures the PRS based on the activated PRS setting information, completes positioning for the UE, and reduces positioning delay. It should be understood here that, in the embodiments of the present invention, the PRS setting information may also be referred to as PRS setting parameters.

[0133] FIG. 5 is a flowchart of a parameter setting method according to an exemplary embodiment. As illustrated in FIG. 5, the parameter setting method is applied to a terminal and includes steps S11 to S12.

[0134] In step S11, a preset set of positioning reference signal (PRS) setting parameters is determined.

[0135] In an embodiment of the present invention, the UE determines a set of PRS setting parameters and pre-sets the set of PRS setting parameters, wherein the set of PRS setting parameters includes at least one set of PRS setting parameters. The UE measures the PRS based on at least one set of PRS setting parameters and determines UE positioning information.

[0136] Here, the PRS setting parameter set can be one of the following situations.

[0137] In the method of performing the work, the PRS setting parameter set may include PRS setting parameters of the same wireless network device, and the PRS setting parameter set includes at least one set of PRS setting parameters.

[0138] In the method of performing the work, a set of PRS setting parameters may include PRS setting parameters of a plurality of different wireless network devices, and said set of PRS setting parameters includes at least one set of PRS setting parameters, and each set of PRS setting parameters corresponds to a PRS setting parameter of a plurality of different wireless network devices.

[0139] In step S12, PRS setting parameters for receiving PRS are determined based on the set of PRS setting parameters.

[0140] In an embodiment of the present invention, the UE can determine a PRS setting according to a preset set of PRS setting parameters, wherein the PRS setting determined based on the PRS setting parameter set is used to receive PRS. As described above, in a method of execution, if the set of PRS setting parameters includes PRS setting parameters of the same wireless network device, the UE determines at least one set of PRS settings based on a different set of PRS setting parameters. In a method of execution, the set of PRS setting parameters includes PRS setting parameters of different wireless network devices, and the UE can determine at least one set of PRS settings based on a preset set of PRS setting parameters, and since each determined set of PRS setting parameters corresponds to PRS setting parameters of a plurality of different wireless network devices, the PRS setting parameters for receiving PRS are determined.

[0141] A UE in some embodiments of the present invention may determine a preset set of PRS setting parameters according to received first instruction information. Here, the first instruction information is used to instruct the UE to preset the set of PRS setting parameters.

[0142] In an embodiment of the present invention, the UE can receive first instruction information based on a random access message (message, MSG) 4 (message) \ MSG 2 of a random access process of the UE and a wireless network device (e.g., a base station).

[0143] In an embodiment of the present invention, the UE can receive first instruction information through a Radio Resource Control (RRC) message.

[0144] In an embodiment of the present invention, the UE can receive first instruction information through downlink control information (DCI).

[0145] In an embodiment of the present invention, the UE can receive first instruction information through an LPP message transmitted from the LMF.

[0146] It should be understood that the UE can determine a preset set of PRS setting parameters included in the LPP message in response to the receipt of an LPP message, receive a preset set of PRS setting parameters through an RRC message or MSG 2 / MSG 4, and decide to use the preset set of PRS setting parameters included in the LPP message.

[0147] In an embodiment of the present invention, a UE may receive second instruction information, wherein the second instruction information is used to instruct a terminal to determine parameters of a PRS setting based on a set of PRS setting parameters. The UE may determine parameters of a PRS setting used to receive the PRS according to the received second instruction information.

[0148] In an embodiment of the present invention, a PRS setting for receiving a PRS determined by a UE may be a subset of a set of PRS setting parameters pre-set by the UE. In an embodiment of the present invention, a PRS setting for receiving a determined PRS is referred to as a subset of PRS setting parameters. That is, a network pre-sets a set of PRS setting parameters to a UE through first instruction information, and said set of PRS setting parameters includes at least one set of PRS setting parameters, and a network sets a set of PRS setting parameters to a UE through second instruction information, and the set of PRS setting parameters set to a UE through second instruction information is a set of PRS setting parameters of one set among a plurality of sets of PRS setting parameters. In an embodiment of the present invention, the second instruction information is

[0149] A first indicator that instructs the terminal to activate PRS setting parameters;

[0150] It includes at least one of a second indicator that instructs the terminal to receive PRS.

[0151] Here, the PRS setting parameter activated by directing the UE is a subset of the PRS setting parameter; and the first indicator and / or the second indicator may be bit-like symbols.

[0152] In one manner of an embodiment of the present invention, the UE determines an activated PRS setting parameter and / or a subset of PRS setting parameters in response to receiving second instruction information containing only a first indicator, and receives a PRS. Here, the first indicator may implicitly instruct the UE to receive a PRS according to the activated PRS setting parameter and / or subset of PRS setting parameters.

[0153] In one method, the UE determines to receive a PRS based on a preset set of PRS setting parameters in response to the received second instruction information containing only a second indicator. In an embodiment of the present invention, when the second instruction information received by the UE contains a second indicator, the UE determines to include only one set of PRS setting parameters in the preset set of PRS setting parameters.

[0154] In one method, the UE determines an activated PRS setting parameter and / or a subset of PRS setting parameters in response to receiving second instruction information including a first indicator and a second indicator, and determines to receive a PRS based on the second indicator.

[0155] In an embodiment of the present invention, the second instruction information may be determined according to an RRC and / or MAC and / or DCI message transmitted from a base station. Alternatively, the second instruction information may be determined based on an LPP message transmitted from an LMF.

[0156] In an embodiment of the present invention, the UE measures the PRS based on PRS setting parameters. Furthermore, the UE receives the PRS according to the determined PRS setting, measures the received PRS, and determines the PRS measurement result. Here, the measurement result may include location information.

[0157] In an embodiment of the present invention, the UE may transmit PRS measurement results or location information to a core network device (e.g., LMF) and / or a wireless network device.

[0158] Based on the same / similar concept, embodiments of the present invention further provide a parameter setting method.

[0160] In step S21, a set of positioning reference signal (PRS) setting parameters is determined.

[0161] In an embodiment of the present invention, the core network device may be an LMF, and the LMF determines at least one set of PRS setting parameters and determines a set of PRS setting parameters according to the determined at least one set of PRS setting parameters.
