[0086] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the embodiments of this disclosure as detailed in the appended claims.

[0087] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. The singular forms “a” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0088] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to a determination."

[0089] For the sake of brevity and ease of understanding, the terms “greater than” or “less than” are used in this document to characterize size relationships. However, it will be understood by those skilled in the art that the term “greater than” also includes the meaning of “greater than or equal to”, and “less than” also includes the meaning of “less than or equal to”.

[0090] In wireless communication technology, sidelink (SL) relay terminals have been introduced, allowing remote terminals or remote UEs to access the network through SL relay terminals.

[0091] In related technologies, a terminal can send location capability indication information to a location management function (LMF) to indicate the terminal's status (e.g., the terminal is a remote terminal). However, during the positioning process, the terminal's status may change, and the LMF may not be able to determine that the terminal's status has changed.

[0092] 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 mobile communication technology. This wireless communication system may include several user equipments 110 and several base stations 120. It should be noted that the user equipment (UE) in this disclosure can be a terminal; it is understood that the terminal in this disclosure can be considered as the user equipment.

[0093] User equipment 110 may be a device that provides voice and / or data connectivity to users. User equipment 110 may communicate with one or more core networks via a Radio Access Network (RAN). User equipment 110 may be an Internet of Things (IoT) user equipment, such as sensor devices, mobile phones, and computers with IoT user equipment capabilities. For example, it may 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. Alternatively, user equipment 110 may also be a device from an unmanned aerial vehicle (UAV). Alternatively, user equipment 110 may also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless user equipment connected to an external vehicle computer. Alternatively, user equipment 110 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0094] Base station 120 can be a network-side device in a wireless communication system. This wireless communication system can be a fourth-generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system; or it can be a 5G system, also known as a New Radio (NR) system; or 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).

[0095] The base station 120 can be an evolved NB (eNB) used in a 4G system. Alternatively, the base station 120 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the base station 120 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 base station 120.

[0096] Base station 120 and user equipment 110 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.

[0097] In some embodiments, user equipment 110 can also establish E2E (End to End) connections. Examples include V2V (vehicle to vehicle), V2I (vehicle to Infrastructure), and V2P (vehicle to pedestrian) communication scenarios in vehicle-to-everything (V2X) communication.

[0098] Here, the user equipment mentioned above can be considered as the terminal equipment in the following embodiments.

[0099] In some embodiments, the wireless communication system described above may further include a network management device 130.

[0100] Several base stations 120 are connected to network management device 130. Network management device 130 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, it 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). The implementation of network management device 130 is not limited in this embodiment.

[0101] To facilitate understanding by those skilled in the art, this disclosure provides multiple embodiments to clearly illustrate the technical solutions of the embodiments of this disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in this disclosure can be executed individually, or in combination with the methods of other embodiments in this disclosure, or individually or in combination with some methods in other related technologies; this disclosure does not limit these aspects.

[0102] To better understand the embodiments of this disclosure, the following exemplary scenarios are provided:

[0103] In one embodiment, see Figure 2 This shows the user plane protocol stack for Layer 2 (L2) terminal network relay.

[0104] In one embodiment, see Figure 3 This shows the control plane protocol stack for Layer 2 (L2) terminal network relay.

[0105] It should be noted that, Figure 2 The boxes in the diagram represent protocol layers. For example, SDAP is the Service Data Adaptation Protocol Layer, and PDCP is the Packet Data Convergence Protocol Layer.

[0106] In one embodiment, for a remote UE, the base station (such as a gNB) can send Radio Resource Control (RRC) messages to the remote UE, but the gNB cannot send Media Access Control (MAC) control elements (CEs). During remote UE positioning, this may cause some positioning functions to be unavailable; for example, it may be impossible to configure aperiodic or semi-persistent Sounding Reference Signals (SRS), configure a Positioning Reference Signal Processing Window (PPW), or configure a pre-configured Measurement Gap (MG) for positioning. Therefore, this disclosure proposes that the remote UE can also send remote UE status indication information when reporting positioning capability information, i.e., the remote UE informs the LMF that it is a remote UE. It also proposes that when a remote UE undergoes a state transition, for example, from a remote UE to a relay UE, it may also send remote UE status indication information to the LMF.

[0107] In one embodiment, to reduce positioning latency, the Access and Mobility Management Function (AMF) can store the UE's positioning capabilities. Then, during the positioning process, the AMF sends the UE's positioning capability information to the LMF (e.g., the positioning capability information is carried in the positioning request sent by the AMF to the LMF), so that the LMF no longer needs to obtain the UE's positioning capability information, thereby reducing positioning latency.

[0108] It's important to note that the AMF stores the UE's capabilities and sends these capabilities to the LMF. However, the LMF does not obtain the latest remote UE status indication information from the UE. Alternatively, during inactive positioning (MT-LR), if the remote UE's status changes (e.g., in periodic positioning scenarios where remote UE status changes are more likely), the LMF will not obtain the latest remote UE status indication information from the UE. In this case, the LMF will be unaware that the terminal's status has changed.

[0109] like Figure 4 As shown, this embodiment provides an information indication method, wherein the method is executed by an access network device, and the method includes:

[0110] Step 41: Send the terminal's status indication information to the first network function;

[0111] The status indication information is used to indicate whether the terminal is a remote terminal or a non-remote terminal.

[0112] Here, the terminal involved in this disclosure may be, but is not limited to, a mobile phone, wearable device, vehicle terminal, roadside unit (RSU), smart home terminal, industrial sensing device and / or medical device, etc. In some embodiments, the terminal may be a Redcap terminal or a predetermined version of a New Radio (NR) terminal (e.g., an R17 NR terminal).

[0113] Here, the access network equipment involved in this disclosure can be various types of base stations, such as base stations of third-generation mobile communication (3G) networks, base stations of fourth-generation mobile communication (4G) networks, base stations of fifth-generation mobile communication (5G) networks, or other evolved base stations.

[0114] Here, the first network function involved in this disclosure may be LMF, but is not limited to LMF, and may also be other network functions.

[0115] In this disclosure, a non-remote terminal can be a relay terminal or a regular terminal. The term "remote terminal" can be understood as the terminal being in a first state; the term "non-remote terminal" can be understood as the terminal being in a second state.

[0116] In one embodiment, the status indication information of the terminal is sent to the first network function via a New Radio Positioning Protocol A (NRPPa) message associated with the terminal; the status indication information is used to indicate whether the terminal is a remote terminal or a non-remote terminal.

[0124] In one embodiment, in response to determining that the terminal has transitioned from a non-remote terminal state to a remote terminal state and updating the terminal's periodic uplink positioning reference signal based on a first configuration parameter to a periodic uplink positioning reference signal based on a second configuration parameter, the status indication information is sent to the first network function via the positioning information update message; wherein, the status indication information is used to indicate that the terminal is a remote terminal. Here, the first configuration parameter and the second configuration parameter may include a period. For example, the first configuration parameter includes a first period, the second configuration parameter includes a second period, and in response to determining that the terminal has transitioned from a non-remote terminal state to a remote terminal state and updating the terminal's periodic uplink positioning reference signal based on the first period to a periodic uplink positioning reference signal based on the second period, the status indication information is sent to the first network function via the positioning information update message; wherein, the status indication information is used to indicate that the terminal is a remote terminal.

[0125] In one embodiment, the status indication information is sent to the first network function via a positioning information failure message; wherein the status indication information is used to indicate that the terminal is a remote terminal or the terminal is a non-remote terminal.

[0126] In one embodiment, in response to receiving a second location information request message sent by the first network function and determining that the terminal is a remote terminal, the status indication information is sent to the first network function through the location information failure message; wherein, the second location information request message is used to request the configuration of an aperiodic uplink positioning reference signal or a semi-persistent uplink positioning reference signal for the terminal; the status indication information is used to indicate that the terminal is a remote terminal.

[0127] In one embodiment, a second location information request message sent by a first network function is received; wherein the second location information request message is used to request the configuration of an aperiodic uplink positioning reference signal or a semi-persistent uplink positioning reference signal for the terminal. A status indication message is sent to the first network function via a location information failure message; the status indication information is used to indicate that the terminal is a remote terminal.

[0128] In one embodiment, a second location information request message sent by a first network function is received; wherein the second location information request message is used to request the configuration of an aperiodic uplink positioning reference signal or a semi-persistent uplink positioning reference signal for the terminal. A status indication message is sent to the first network function via a location information failure message; the status indication information is used to indicate that the terminal is a remote terminal.

[0129] In one embodiment, the status indication information of the terminal is sent to the first network function via a measurement preconfiguration refuse message; wherein the status indication information is used to indicate whether the terminal is a remote terminal or a non-remote terminal.

[0130] In one embodiment, in response to receiving a measurement preconfiguration request message sent by the first network function and determining that the terminal is a remote terminal, the status indication information of the terminal is sent to the first network function via a measurement preconfiguration rejection message; wherein, the status indication information is used to indicate that the terminal is a remote terminal; the measurement preconfiguration request message is used to request the configuration of a positioning reference signal processing window (PPW) or a preconfigured measurement interval (MG) for the terminal.

[0132] In one embodiment, the information field of the location information failure message and / or the measurement pre-configuration rejection message includes a cause value information field, which indicates that the terminal is a remote terminal.

[0133] In this embodiment of the disclosure, a terminal status indication information is sent to a first network function; the status indication information is used to indicate whether the terminal is a remote terminal or a non-remote terminal. Here, since the access network device sends the status indication information indicating whether the terminal is a remote terminal or a non-remote terminal to the first network function, the first network function can determine the terminal's status based on the status indication information after the terminal's status changes. Compared to the situation where it is impossible to determine whether the terminal is a remote terminal or a non-remote terminal, this improves the reliability of wireless positioning during the wireless positioning process.
