Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The present disclosure provides a method for configuring a positioning reference signal, which may be applied to a wireless communication system shown in fig. 1, as shown in fig. 1, a terminal accesses to a radio access network through a radio access network device such as a base station, and the radio access network device and a core network device complete backhaul and forward transfer of data to perform various communication services.

It is understood that a wireless communication system is a network providing wireless communication functions. Wireless communication systems may employ 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 (Carrier Sense Multiple Access). Networks can be classified into 2G (english: generation) networks, 3G networks, 4G networks or future evolution networks, such as 5G networks, according to factors such as capacity, rate and delay of different networks, and the 5G networks can also be referred to as New Radio Networks (NR). For ease of description, this disclosure will sometimes simply refer to a wireless communication network as a network or system. In the present disclosure, a Network may include a Radio Access Network (RAN) and a Core Network (Core Network, CN). Included in the network are network devices, which may be, for example, wireless network devices, core network devices, and the like. The wireless network device may also be referred to as a base station, among others. The network can provide network services for the terminal through the network device, different operators can provide different network services for the terminal, and different operators can also be understood as different operator networks corresponding to different operators. For example, in 5G NR, a wireless network device may be referred to as a gNB.

A Terminal (Terminal), sometimes referred to as a Mobile Station (MS), may also be referred to as a User Equipment (UE), a Mobile Terminal (MT), etc., is a device that provides voice and/or data connectivity to a User, for example, the Terminal may be a handheld device, a vehicle-mounted device, etc. with a wireless connection function. Currently, some examples of terminals are: a smart Phone (Mobile Phone), a Pocket Computer (PPC), a palm top Computer, a Personal Digital Assistant (PDA), a notebook Computer, a tablet Computer, a wearable device, or a vehicle-mounted device, etc. In the embodiments of the present disclosure, a terminal is referred to as a UE as an example.

5G R16 introduces a variety of positioning technologies that can enable positioning of a UE, some of which the network needs to send a configuration of PRS to the UE. The network may transmit the PRS configuration to the UE through the communication procedures shown in fig. 2 and 3. The procedure of configuring PRS for UE is described by taking downlink time difference of arrival (DL-TDOA) as an example. Fig. 2 is an interaction flow diagram for PRS configuration by a wireless network device and a core network device in an exemplary embodiment. Referring to fig. 2, the LMF transmits DL-TDOA request information to the gNB through NR Positioning Protocol a (NRPPa), and the gNB transmits a DL-TDOA response message to the LMF after receiving the request, where the response message includes PRS configuration information of the base station. When the LMF receives the PRS configuration information, the PRS configuration information may be transmitted to the UE through a procedure as shown in fig. 3. Fig. 3 shows an interaction flowchart of configuring PRS configuration information for a terminal by a core network device in an exemplary embodiment. Referring to fig. 3, the LMF includes PRS configuration information of a base station in an LTE Positioning Protocol (LPP) message transmitted to the UE. Or, the LMF provides a positioning system message to the gNB, and the gNB sends the positioning system message, wherein the positioning system message includes the configuration information of the PRS.

However, the PRS configuration procedure of R16 is for a periodic PRS configuration, that is, after the network sends a periodic PRS configuration to the UE, the UE can always determine the PRS according to the PRS configuration, and meanwhile, the network sends the PRS configuration periodically according to the PRS. R17 considers introducing aperiodic PRS and semi-persistent PRS, the current procedure of configuring PRS to UE will not satisfy the requirement of configuring aperiodic PRS and semi-persistent PRS configuration, and therefore, the existing PRS configuration procedure needs to be enhanced.

The embodiment of the present disclosure provides a PRS configuration method, in which a core network device requests and indicates PRS configuration information to a wireless network device, where the PRS configuration information includes at least one of a periodic PRS configuration, a non-periodic PRS configuration, and a semi-persistent PRS configuration. The core network equipment and/or the wireless network equipment determine the PRS configuration information and configure the PRS configuration information to the terminal, so that the downlink positioning is carried out by using the non-periodic positioning reference signal or the semi-continuous positioning reference signal, the positioning precision is improved, and the positioning time delay is reduced.

Fig. 14 is a flowchart illustrating a PRS configuration method for use in a terminal according to an exemplary embodiment. The PRS configuration method as shown in fig. 14 further includes step S33.

The PRS configuration method provided by the embodiment of the disclosure enables the terminal to utilize the non-periodic PRS or the semi-continuous PRS when performing downlink positioning, thereby improving the positioning accuracy and reducing the positioning delay.

It can be understood that the PRS configuration method provided by the embodiment of the present disclosure may also be applied to an interaction process of a terminal, a wireless network device and a core network device. The method for implementing the implementation process of the PRS configuration method interactively implemented by the terminal, the wireless network device and the core network device may refer to the relevant description of the above embodiments.

The PRS configuration method according to the embodiment of the present disclosure is described below with reference to practical applications. In the embodiment of the present disclosure, a core network device is an LMF, a wireless network device is a gNB, and a terminal is a UE. The main flow of implementing the PRS configuration by the LMF, the gNB and the UE is as follows:

The LMF sends an NRPPa message to the gNB, wherein the NRPPa message comprises indication information for indicating that the PRS type requested by the LMF to the gNB is at least one of PRS configuration information of periodic PRS configuration, aperiodic PRS configuration and semi-persistent PRS configuration.

And 2, after receiving the NRPPa message, the gNB determines to send PRS configuration information to the LMF according to the PRS type requested by the LMF in the indication. For example, if the PRS type requested by the LMF is aperiodic PRS, then the gNB sends an aperiodic PRS configuration to the LMF.

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

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 periodic PRS configuration information from the gNB, but the gNB sends aperiodic PRS configuration information to the LMF.

3.2. the LMF sends PRS configuration information of a plurality of gNBs participating in UE positioning to the gNB receiving the NRPPa message.

For positioning of the UE, multiple TRPs are required to participate, which may be multiple TRPs of one gNB on one hand, and multiple TRPs of multiple gnbs on the other hand. When the positioning of the UE needs a plurality of TRPs corresponding to a plurality of gnbs, PRS configuration information of other gnbs is also sent to the gnbs corresponding to the UE serving cell. If it is multiple TRPs of one gNB that participate in UE positioning, step 3.2 need not be performed.

And 4, the gNB sends the PRS configuration information to the UE.

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

6. If the LMF configures semi-static or non-periodic PRS to the UE, the LMF sends indication information to the gNB, wherein the indication information is used for indicating the gNB to activate the semi-static or non-periodic PRS transmission.

When the gNB receives the PRS configuration information of other gNBs and/or the LMF indicates the gNB to activate PRS transmission of other gNBs, the gNB sends indication information to other gNBs through the Xn interface to indicate the other gNBs to activate semi-static or non-periodic PRS transmission.

It can be understood that when the multiple TRPs participating in UE positioning are multiple TRP scenarios of multiple gnbs, the LMF is required to send indication information to the multiple gnbs. The LMF sends the indication information to the gNB to which the UE serving cell belongs, and the gNB to which the UE serving cell belongs sends the indication information to other gNBs.

And 7, the gNB sends a DCI (DCI) to the UE, and the UE receives the DCI and receives the PRS according to the received PRS configuration.

Fig. 15 is a flowchart illustrating a PRS configuration method used in an interaction procedure of an LMF, a gNB, and a UE according to an exemplary embodiment. Referring to fig. 15, the gNB1 is a base station corresponding to a serving cell of the UE (generally, one base station includes multiple cells). The gNB2 is a base station corresponding to a neighboring cell of the UE, and participates in positioning of the UE. Wherein the LMF requests the aperiodic PRS configuration from the gNB1 through an NRPPa message. The LMF requests aperiodic PRS configuration from the gNB2 through NRPPa message. The gNB1 decides the aperiodic PRS configuration and sends the aperiodic PRS configuration to the LMF through an NRPPa message. The gNB2 decides the aperiodic PRS configuration and sends the aperiodic PRS configuration to the LMF through an NRPPa message. The LMF transmits an aperiodic PRS configuration to the UE through the LPP, the aperiodic PRS configuration including PRS configurations of the gNB1 and the gNB 2. The LMF sends an active aperiodic PRS configuration to the gNB1 through an NRPPa message, and the gNB sends aperiodic PRS. The LMF sends an active aperiodic PRS configuration to the gNB2 via an NRPPa message, which sends an aperiodic PRS. And the gNB1 sends an indication of activating the aperiodic PRS to the UE through the DCI, and the UE receives the PRS according to the configuration.

It can be understood that the PRS configuration procedure shown in fig. 15 may also be performed without participation of a base station corresponding to a UE neighboring cell, that is, without participation of the gNB2, where multiple TRPs corresponding to the gNB1 may complete positioning of the UE.

Fig. 16 is a flowchart illustrating a PRS configuration method used in an interaction procedure of an LMF, a gNB, and a UE according to an exemplary embodiment. Referring to fig. 16, the gNB1 is a base station corresponding to a serving cell of the UE (generally, one base station includes multiple cells). And the gNB2 is a base station corresponding to the adjacent cell of the UE and participates in the positioning of the UE. Wherein the LMF requests the aperiodic PRS configuration from the gNB1 through an NRPPa message. The LMF requests aperiodic PRS configuration from the gNB2 through NRPPa message. The gNB1 decides the aperiodic PRS configuration and sends the aperiodic PRS configuration to the LMF through an NRPPa message. The gNB2 decides the aperiodic PRS configuration and sends the aperiodic PRS configuration to the LMF through an NRPPa message. The LMF sends an aperiodic PRS configuration to the gNB1 through the NRPPa, the aperiodic PRS configuration including PRS configurations of the gNB1 and the gNB 2. The gNB1 transmits the received aperiodic PRS configuration to the UE through an RRC message. The LMF sends an activated aperiodic PRS configuration to the gNB1 through an NRPPa message, and the gNB1 sends an aperiodic PRS. The gNB1 sends an active aperiodic PRS configuration to the gNB2 via an Xn message, and the gNB2 sends an aperiodic PRS. And the gNB1 sends an indication of activating the aperiodic PRS to the UE through the DCI, and the UE receives the PRS according to the activated PRS configuration.

It can be understood that the PRS configuration procedure in fig. 16 may also be performed without participation of base stations corresponding to UE neighboring cells, that is, without participation of the gNB2, where multiple TRPs corresponding to the gNB1 may complete positioning of the UE.

By the PRS configuration method provided by the disclosure, the core network equipment and the wireless network equipment can carry out the configuration of the non-periodic PRS or the semi-continuous PRS, and the terminal can utilize the non-periodic PRS or the semi-continuous PRS when carrying out downlink positioning, thereby improving the positioning accuracy and reducing the positioning time delay.
