Description

Positioning method, terminal device and network device Technical Field

[0001] The present application relates to the field of communication technology, and more specifically, to a positioning method, terminal device, and network device. Background Art

[0002] In satellite communication systems, terminal devices need to determine their own location information based on satellites. After determining their location, the terminal device can estimate the two-way transmission delay of the service link between the satellite and the terminal device and pre-compensate for this delay during each uplink transmission. This pre-compensation for transmission delay enables the satellite communication system to maintain synchronization between terminal devices. However, if the satellite signal deteriorates or the terminal device loses satellite signal reception, there is currently no suitable solution for how the terminal device should respond.

[0047] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move based on the location of the mobile base station.

[0048] In some deployments, the network device in the embodiments of the present application may refer to a CU or a DU, or the network device may include a CU and a DU. The gNB may also include an AAU.

[0049] The network equipment and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; they can also be deployed in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the scenarios in which the network equipment and terminal devices are located.

[0050] As an example and not a limitation, in an embodiment of the present application, the network device may have a mobile feature, for example, the network device may be a mobile device. In some embodiments of the present application, the network device may be a satellite or a balloon station. For example, the satellite may be a low earth orbit (LEO) satellite, a medium earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. In some embodiments of the present application, the network device may also be a base station set up in a location such as land or water.

[0051] In an embodiment of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through the transmission resources used by the cell (for example, frequency domain resources, or spectrum resources). The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0052] For example, Figure 1A is a schematic diagram of the architecture of a communication system provided in an embodiment of the present application. As shown in Figure 1A, the communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or also referred to as a communication terminal or terminal). The network device 110 may provide communication coverage for a specific geographic area and may communicate with terminal devices located within the coverage area.

[0053] Figure 1A exemplarily shows a network device and two terminal devices. In some embodiments of the present application, the communication system 100 may include multiple network devices and each network device may include other number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0054] For example, FIG1B is a schematic diagram of the architecture of another communication system provided in an embodiment of the present application. Referring to FIG1B , a terminal device 1101 and a satellite 1102 are included, and wireless communication can be performed between the terminal device 1101 and the satellite 1102.

In the architecture of the communication system shown in FIG1B , the satellite 1102 can have the function of a base station, and the terminal device 1101 and the satellite 1102 can communicate directly. In the system architecture, the satellite 1102 can be referred to as a network device. In some embodiments of the present application, the communication system may include multiple network devices 1102, and each network device 1102 may include other numbers of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0055] For example, FIG1C is a schematic diagram of the architecture of another communication system provided in an embodiment of the present application.

Wireless communication can be performed between the terminal device 1201 and the satellite 1202, and communication can be performed between the satellite 1202 and the base station 1203. The network formed between the terminal device 1201, the satellite 1202, and the base station 1203 can also be referred to as an NTN. In the architecture of the communication system shown in FIG1C , the satellite 1202 may not have the function of a base station, and the communication between the terminal device 1201 and the base station 1203 needs to be transferred through the satellite 1202. In this system architecture, the base station 1203 can be referred to as a network device. In some embodiments of the present application, a plurality of network devices 1203 may be included in the communication system, and each network device 1203 may include other number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0056] It should be noted that Figures 1A-1C are only examples of the system to which this application is applicable. Of course, the method shown in the embodiment of this application can also be applied to other systems, such as 5G communication systems, LTE communication systems, etc., and the embodiment of this application does not make specific limitations on this.

[0057] In some embodiments of the present application, the wireless communication system shown in Figures 1A-1C may also include other network entities such as a mobility management entity (MME) and an access and mobility management function (AMF), but the embodiments of the present application are not limited to this.

[0058] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system 100 shown in FIG1A as an example, the communication device may include a network device 110 and a terminal device 120 having a communication function. The network device 110 and the terminal device 120 may be the specific devices described above and will not be described in detail here. The communication device may also include other devices in the communication system 100, such as a network controller, a mobility management entity, and other network entities, which are not limited in the embodiments of the present application.

[0059] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0060] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0061] The “configuration” in the embodiment of the present application may include configuration through at least one of system messages, radio resource control (RRC) signaling and media access control element (MAC CE).

[0062] In some embodiments of the present application, "predefined" or "preset" may be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (e.g., a terminal device or a network device). This application does not limit the specific implementation method. For example, predefined may refer to information defined in a protocol.

[0063] In some embodiments of the present application, the "protocol" may refer to a standard protocol in the field of communications, for example, it may include an LTE protocol, an NR protocol, and related protocols used in future communication systems, and this application does not limit this.

[0064] The Third Generation Partnership Project (3GPP) is currently researching NTN technology. NTN typically uses satellite communications to provide communication services to terrestrial users. Compared to terrestrial cellular networks, satellite communications offer many unique advantages.

[0065] First, satellite communications are not restricted by user geography. For example, conventional terrestrial communication networks cannot cover areas where network equipment cannot be deployed, such as oceans, mountains, and deserts. Similarly, terrestrial communication networks do not cover certain sparsely populated areas. However, because satellite communications can cover a large ground area and orbit the Earth, theoretically, every corner of the Earth can be covered by a satellite communication network.

[0066] Secondly, satellite communications have significant social value. They can provide low-cost coverage to remote, mountainous areas and impoverished countries and regions, enabling people in these areas to enjoy advanced voice communications and mobile internet technologies. From this perspective, satellite communications help narrow the digital divide with developed regions and promote their development.

[0067] Again, satellite communication has the advantage of long distance, and the increase in communication distance does not significantly increase the cost of communication.

[0068] Finally, satellite communications are highly stable and not affected by natural disasters.

[0069] Communication satellites are classified according to their orbital altitude into low Earth orbit (LEO), medium Earth orbit (MEO), geostationary Earth orbit (GEO), and high elliptical orbit (HEO). Currently, research focuses on LEO and GEO satellites.

[0070] LEO satellites typically operate at altitudes between 500 and 1500 km. Accordingly, their orbital period is approximately 1.5 to 2 hours. For LEO satellites, the signal propagation delay for single-hop communication between users is typically less than 20 milliseconds. The maximum satellite visibility time for LEO satellites is approximately 20 minutes. LEO satellites offer advantages such as short signal propagation distances, low link loss, and low transmit power requirements for user devices.

[0071] GEO satellites orbit at an altitude of 35,786 km. They orbit the Earth every 24 hours. For GEO satellites, the signal propagation delay for single-hop communication between users is typically about 250 milliseconds.

[0072] To ensure satellite coverage and increase the capacity of the entire satellite communication system, satellites typically use multiple beams to cover the ground. Therefore, a single satellite can form dozens or even hundreds of beams to cover the ground. A single satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers.

[0073] Currently, the NTN system includes the NR-NTN system and the Internet of Things (IoT)-NTN system.

[0074] Currently, 3GPP is considering two types of satellites: those with transparent payloads and those with regenerative payloads. The following describes the network architectures for satellites with transparent payloads and those with regenerative payloads, respectively, using Figures 2 through 4.

[0075] In the satellite network architecture shown in Figures 2 to 4, the satellite network architecture may include a terminal device 210, a satellite node 222, and a ground receiving station 221 (referred to as a "ground station"). Wireless communication exists between the terminal device 210 and the satellite node 222. The terminal device 210 can send data to the satellite node 222 via the link between the terminal device 210 and the satellite node 222. For example, data can be sent to the satellite node 222 via a service link. Accordingly, after receiving the data, the satellite node 222 can send the data to the ground receiving station 221 via the link between the satellite node 222 and the ground receiving station 221. For example, the data can be transmitted to the ground receiving station 221 via a wireless link (such as a feeder link). Accordingly, after receiving the data from the satellite node 222, the ground receiving station 221 transmits the data to the core network (data network), which then processes the data via the core network, such as for data exchange with other terminals. It can be understood that the service link here refers to the link between the terminal device 210 and the satellite node 222, and the feeder link refers to the link between the satellite node 222 and the ground receiving station 221. In other possible embodiments, the link between the terminal device and the satellite node, and / or the link between the satellite node and the ground receiving station can also be expressed by other terms, which are not limited in this application.

[0076] The above-mentioned satellite nodes 222 can be divided into three types. The first type of satellite node is only used for forwarding, that is, it only has a transparent forwarding function. In some implementations, such satellite nodes may only provide one or more of a radio frequency filtering function, a frequency conversion function, and a power amplification function. For this type of satellite node, the received terminal device signal is amplified and then sent to the ground receiving station without any processing on the satellite node, as shown in Figure 2; wherein, the terminal device and the satellite node can communicate through the NR-Uu interface, the satellite node and the ground receiving station (such as the NTN radio frequency remote unit (RRU) and gNB) can communicate through the NR-Uu interface, the ground receiving station and the 5G core network (5G CN) can communicate through the N1 / 2 / 3 interface, and the 5G CN and the data network can communicate through the N6 interface.

[0077] The second type of satellite node has complete base station processing functions. The satellite node is a base station for the terminal equipment on the ground. The communication between the satellite node and the terminal equipment is basically the same as normal 5G communication, as shown in Figure 3. In some implementations, such satellite nodes can also provide one or more of the following functions: demodulation function, decoding function, routing function, conversion function, encoding function, and modulation function. Among them, the terminal equipment and the satellite node can communicate through the NR-Uu interface, and the satellite node and the ground receiving station can communicate through the satellite radio interface (SRI). The SRI interface can be used to send interface messages between the satellite node and the 5G CN (such as N2 / N3 interface messages). The ground receiving station and the 5G CN can communicate through the N1 / 2 / 3 interface, and the 5G CN and the data network can communicate through the N6 interface.

[0078] The third type of satellite node has DU processing capabilities. To ground-based terminal devices, the satellite node appears as a DU. Communication between the satellite node and terminal devices is essentially the same as that between terminal devices and DUs in a normal 5G terrestrial communication system, as shown in Figure 4. Terminal devices and satellite nodes can communicate via the NR-Uu interface, while satellite nodes and ground receiving stations (such as gNB-CUs) can communicate via the SRI interface, which transmits F1 interface messages between the satellite and ground receiving stations. Ground receiving stations and 5G CNs can communicate via the N1 / 2 / 3 interfaces, and the 5G CN and data networks can communicate via the N6 interface.

[0079] In a satellite communication system (such as the NTN system), the terminal device needs to support satellite-based positioning capabilities (for example, the terminal device needs to have global navigation satellite system (GNSS) capabilities) to determine the location of the terminal device. After determining the location information of the terminal device, the terminal device can evaluate the two-way transmission delay of the service link between the satellite and the terminal device, and pre-compensate the transmission delay during each uplink transmission. By pre-compensating the transmission delay, the satellite communication system is able to maintain synchronization between terminal devices. However, in certain situations (such as when the terminal device enters a tunnel, or the global positioning system (GPS) of the terminal device is unavailable), the satellite-based positioning accuracy of the terminal device deteriorates, or it may be temporarily unable to update its own location information based on the satellite. If the above situation occurs, the location information of the terminal device may become less accurate for a period of time. At this time, there is no suitable solution for how the terminal device should respond.

[0080] In response to the above problems, the embodiments of the present application are described in detail below.

[0081] Figure 5 is a flowchart illustrating a positioning method provided in an embodiment of the present application. The method in Figure 5 is described from the perspective of the interaction between a terminal device and a network device. The terminal device may be a terminal device in an NTN NR communication system. Alternatively, the terminal device may be a terminal device in an NTN IoT system. Alternatively, the terminal device may be any type of terminal device capable of supporting the positioning method provided in an embodiment of the present application.

[0082] 5 , in step S510 , the terminal device sends first information to the network device. The first information may be carried in MAC CE, radio resource control (RRC) or uplink control information (UCI).

[0083] In some implementations, the first information is associated with the validity of the first location information. The first location information mentioned here is determined based on a first positioning method. The first positioning method mentioned in the embodiments of the present application refers to a satellite-based positioning method. The satellites mentioned here may refer to positioning navigation satellites. Positioning navigation satellites may include, for example, one or more of the following: GPS satellites, GNSS satellites, Galileo satellites, and Beidou satellites.

[0084] In some implementations, the first information being associated with the validity of the first location information may include or be replaced by: the first information being associated with measurements of the first positioning method. For example, the first information being associated with GNSS measurements.

[0085] In some implementations, the validity association between the first information and the first location information may include or be replaced by: the first information is used to indicate one or more of the following: a first time period, the first time period is the valid time period of the first location information; the first location information is invalid or is about to expire; the accuracy of the first location information does not meet the conditions (or, the accuracy of the first location information deteriorates).

[0086] In some implementations, the first information is sent when measurement based on the first positioning method is unavailable, has deteriorated in accuracy, is about to become unavailable, or is about to deteriorate in accuracy.

[0087] In some implementations, the validity association of the first information with the first location information may include or be replaced by: the first information is used to determine a remaining validity period of the terminal device's location information (or location information determined based on a satellite positioning method). In other words, if the remaining validity period determined based on the first information expires, the terminal device's location information (or location information determined based on a satellite positioning method) becomes invalid.

[0088] In an embodiment of the present application, a terminal device sends first information to a network device. This first information is important to the network device and helps the network device better schedule the terminal device. For example, the network device can accurately obtain the remaining validity period of the location information determined based on satellite positioning based on the first information. Then, after the remaining validity period expires, the network device can enable the terminal device to use other positioning methods for positioning to restore the terminal device's location information. Alternatively, the network device can schedule the terminal device to suspend the transmission of important information after the remaining validity period expires, thereby avoiding information loss.

[0089] In some implementations, when the first location information of the terminal device fails or is about to fail, or when the terminal device cannot obtain satellite positioning data (such as GNSS data) or the satellite positioning data is unavailable, the network device may enable a second positioning method. The second positioning method is another positioning method different from the first positioning method. In other words, the second positioning method is other positioning methods that are not based on satellites. The second positioning method can be used to locate the terminal device when the first location information fails (that is, the location information determined based on the satellite fails). Since the network device may not know that the first location information of the terminal device has failed or is about to fail, the terminal device may request the second positioning method. For example, the terminal device may request the network device to enable the second positioning method based on the first information mentioned above.

[0090] In some implementations, the method of FIG. 5 further includes step S520, where the terminal device receives second information sent by the network device. The second information is associated with a second positioning method. For example, the second information is used to enable the second positioning method. After enabling the second positioning method, the terminal device can obtain accurate location information based on the second positioning method. The second positioning method can, for example, be a positioning method based on positioning reference signal resources.

[0091] In some implementations, the above-mentioned second information associated with the second positioning method may include or be replaced by: the second information is used to activate the positioning reference signal resource. It should be understood that the positioning reference signal mentioned here can be any type of reference signal that can play a positioning role. For example, it can be a positioning reference signal (PRS) or a sounding reference signal (SRS) that can be used for positioning. In some implementations, the network device can pre-configure one or more positioning reference signal resources for the terminal device, and the one or more positioning reference signal resources are in an inactivated state by default. After the terminal device receives the second information from the network device, the one or more positioning reference signal resources are activated.

[0092] The embodiment of the present application does not specifically limit the carrying method of the second information. For example, the second information can be carried by downlink control information (DCI) or by MAC CE. Two possible implementation methods are given below.

[0093] Implementation method 1: The second information is carried by the first DCI (or the first DCI format)

[0094] If the second information is used to activate the positioning reference signal resource, the second information is carried in the first DCI, indicating that activation of the positioning reference signal resource is triggered by the first DCI.

[0095] The embodiment of the present application does not specifically limit the type of the first DCI. For example, the first DCI may include DCI for scheduling PUSCH and / or PDSCH. Exemplarily, the DCI format of the first DCI is DCI format 1_0, DCI format 1_1, DCI format 0_0 or DCI format 0_1. The above-mentioned DCI format can use the cell radio network temporary identifier (C-RNTI) for cyclic redundancy check (CRC) scrambling. For another example, the first DCI may include DCI that is not used for scheduling PUSCH and / or PDSCH. For another example, the first DCI may include group common DCI.

[0096] In some implementations, the first DCI may be used to activate: positioning reference signal resources corresponding to one or more cells; and / or positioning reference signal resources corresponding to one or more TRPs.

[0097] For example, the first DCI may include activation information of the first cell (belonging to the second information mentioned above). The activation information is located at the first position in the first DCI, and the first position is preconfigured by the network device for the terminal device.

[0098] For another example, the first DCI may include activation information of the first TRP (belonging to the second information mentioned above). The activation information is located at the first position in the first DCI, and the first position is preconfigured by the network device for the terminal device.

[0099] In some implementations, the first DCI includes one or more indication fields. The one or more indication fields are used to activate a positioning reference signal. For example, the first DCI includes an indication field for activating a positioning reference signal. The indication field may be a newly added indication field (relative to legacy DCI). Alternatively, the indication field may reuse an existing indication field in the DCI. For another example, the first DCI may include multiple indication fields. The combination of values ​​of the multiple indication fields may be predefined or configured based on a network device. Once the combination of values ​​of the multiple indication fields meets a condition, the terminal device determines that the multiple indication fields are used to indicate activation of a positioning reference signal.

[0100] In some implementations, the first DCI is transmitted in a monitoring occasion (MO) of the DCI configured by the network device. The monitoring occasion can be determined based on the configuration information of the network device. Since the network device may not be able to know in advance whether the first location information of the terminal device is valid, the network device does not actively activate the positioning reference signal configured for the terminal device. Therefore, the terminal device does not need to monitor the DCI in the monitoring occasion before sending the first information to the network device. After the terminal device sends the first information to the network device, the terminal device can start to monitor the DCI through the monitoring occasion. Accordingly, the network device can transmit the first DCI through the monitoring occasion after receiving the first information sent by the terminal device.

[0101] Implementation method 2: The second information is carried by the first MAC CE

[0102] If the second information is used to activate the positioning reference signal resource, the second information is carried in the first MAC CE, indicating that activation of the positioning reference signal resource is triggered by the first MAC CE.

[0103] In some implementations, the effective time of the second information (or the activation time of the positioning reference signal resource) may be determined based on the transmission time of the feedback information (e.g., acknowledgment (ACK) information) corresponding to the first MAC CE and / or the first delay. For example, the effective time of the second information may be the transmission time of the feedback information plus the first delay. The first delay mentioned here may be determined based on predefined information or by configuration information of the network device.

[0104] In some implementations, the first MAC CE is used to activate one or more of the following: positioning reference signal resources corresponding to one or more cells; positioning reference signal resources corresponding to one or more transmission reception points (TRPs); and positioning reference signal resources corresponding to one or more bandwidth parts (BWPs).

[0105] For example, the first MAC CE may include identifiers of one or more cells and their corresponding activation fields (used to store activation information of the positioning reference signal).

[0106] For another example, the first MAC CE may include identifiers of one or more BWPs and their corresponding activation fields (used to store activation information of the positioning reference signal).

[0107] For another example, the first MAC CE may include identifiers of one or more TRPs and their corresponding activation fields (used to store activation information of the positioning reference signal).

[0108] In some implementations, the terminal device expects to receive the second information before the end of the second time period. Alternatively, the terminal device does not expect to receive the second information after the end of the second time period.

[0109] The second period mentioned above may be the same period as the first period mentioned above, or may be a different period from the first period. In some implementations, the start time of the second period is associated with the time when the first information is sent. For example, the start time of the second period is the same as the time when the first information is sent. The duration of the second period may be determined based on protocol predefined information and network device configuration information. Alternatively, the duration of the second period may be reported by the terminal device.

[0110] In some implementations, the second information is carried in the first MAC CE, and the transmission time of the feedback information corresponding to the first MAC CE should be earlier than the end time of the second time period.

[0111] In some implementations, after the first period ends, the terminal device enters an idle state, which can save power consumption.

[0112] In some implementations, if the second information is not received, the terminal device enters an idle state. When the terminal device enters the idle state, power consumption can be saved.

[0113] In some implementations, the terminal device sends third information to the network device. The third information is used to notify the network device that the terminal device is about to enter the idle state. The third information can be carried in a physical random access channel (PRACH).

[0114] In some implementations, if the second information is not received, the terminal device sends third information to the network device. The third information is used to notify the network device that the terminal device is about to enter the idle state. The third information can be carried in the PRACH.

[0115] In some implementations, after the first period ends, if the time alignment timer (TAT) is still running, the terminal device continues uplink transmission. This is because during the TAT period, the network device can still correct the time error by adjusting the timing advance (TA).

[0116] In some implementations, if the second information is not received and the TAT is still running, the terminal device continues to perform uplink transmission.

[0117] In some implementations, after the first time period ends, if the location information of the terminal device is still in an invalid state, the terminal device performs downlink transmission instead of uplink transmission.

[0118] Alternatively, in some implementations, the first information refers to information sent when the first location information fails, is about to fail, or deteriorates, and the first information is used to request the second positioning method.

[0119] Figure 6 is a flowchart illustrating a positioning method provided by another embodiment of the present application. The method in Figure 6 is described from the perspective of the interaction between a terminal device and a network device. The terminal device may be a terminal device in an NTN NR communication system. Alternatively, the terminal device may be a terminal device in an NTN IoT system. Alternatively, the terminal device may be any type of terminal device capable of supporting the positioning method provided by an embodiment of the present application.

[0120] Referring to Figure 6, in step S610, the terminal device receives second information sent by the network device. The second information is associated with a second positioning method, which is used to locate the terminal device when the first location information (for a description of the first location information, see the embodiment corresponding to Figure 5) fails.

[0121] For example, the second information is used to enable a second positioning method. After the second positioning method is enabled, the terminal device can obtain accurate location information based on the second positioning method. The second positioning method can be, for example, a positioning method based on positioning reference signal resources.

[0122] In some implementations, the association of the second information with the second positioning method may include or be replaced by: the second information is used to activate positioning reference signal resources. It should be understood that the positioning reference signal mentioned here can be any type of reference signal resource that can play a positioning role, such as a PRS or SRS. For example, the network device may pre-configure one or more positioning reference signal resources for the terminal device, and the one or more positioning reference signal resources are in an inactivated state by default. After the terminal device receives the second information from the network device, the one or more positioning reference signal resources are activated.

[0123] The embodiment of the present application does not specifically limit the carrying method of the second information. For example, the second information can be carried by DCI or MAC CE. Two possible implementation methods are given below.

[0124] Implementation method 1: The second information is carried by the first DCI (or the first DCI format)

[0125] If the second information is used to activate the positioning reference signal resource, the second information is carried in the first DCI, indicating that activation of the positioning reference signal resource is triggered by the first DCI.

[0126] The embodiment of the present application does not specifically limit the type of the first DCI. For example, the first DCI may include DCI for scheduling PUSCH and / or PDSCH. Exemplarily, the DCI format of the first DCI is DCI format 1_0, DCI format 1_1, DCI format 0_0, or DCI format 0_1. The above DCI formats can use C-RNTI for CRC scrambling. For another example, the first DCI may include DCI that is not used for scheduling PUSCH and / or PDSCH. For another example, the first DCI may include group-common DCI.

[0127] In some implementations, the first DCI may be used to activate: positioning reference signal resources corresponding to one or more cells; and / or positioning reference signal resources corresponding to one or more TRPs.

[0128] For example, the first DCI may include activation information of the first cell (belonging to the second information mentioned above). The activation information is located at the first position in the first DCI, and the first position is preconfigured by the network device for the terminal device.

[0129] For another example, the first DCI may include activation information of the first TRP (belonging to the second information mentioned above). The activation information is located at the first position in the first DCI, and the first position is preconfigured by the network device for the terminal device.

[0130] In some implementations, the first DCI includes one or more indication fields. The one or more indication fields are used to activate a positioning reference signal. For example, the first DCI includes an indication field for activating a positioning reference signal. The indication field may be a newly added indication field (relative to legacy DCI). Alternatively, the indication field may reuse an existing indication field in the DCI. For another example, the first DCI may include multiple indication fields. The combination of values ​​of the multiple indication fields may be predefined or configured based on a network device. Once the combination of values ​​of the multiple indication fields meets a condition, the terminal device determines that the multiple indication fields are used to indicate activation of a positioning reference signal.

[0131] In some implementations, the first DCI is transmitted in the MO of the DCI configured by the network device. The monitoring opportunity can be determined based on the configuration information of the network device. Since the network device cannot obtain a priori information on whether the first location information of the terminal device is valid, the network device does not actively activate the positioning reference signal configured for the terminal device. Therefore, the terminal device does not need to monitor the DCI in the monitoring opportunity before sending the first information to the network device, but only needs to start monitoring the DCI through the monitoring opportunity after the terminal device sends the first information to the network device. Accordingly, the network device can transmit the first DCI through the monitoring opportunity after receiving the first information sent by the terminal device.

[0132] Implementation method 2: The second information is carried by the first MAC CE

[0133] If the second information is used to activate the positioning reference signal resource, the second information is carried in the first MAC CE, indicating that activation of the positioning reference signal resource is triggered by the first MAC CE.

[0134] The effective time of the second information (or the activation time of the positioning reference signal resource) is determined based on the transmission time of the feedback information (e.g., ACK information) corresponding to the first MAC CE and / or the first delay. For example, the effective time of the second information may be the transmission time of the feedback information plus the first delay. The first delay mentioned here may be based on predefined information or determined by configuration information of the network device.

[0135] In some implementations, the first MAC CE is used to activate one or more of the following: positioning reference signal resources corresponding to one or more cells; positioning reference signal resources corresponding to one or more TRPs; and positioning reference signal resources corresponding to one or more BWPs.

[0136] For example, the first MAC CE may include identifiers of one or more cells and their corresponding activation fields (used to store activation information of the positioning reference signal).

[0137] For another example, the first MAC CE may include identifiers of one or more BWPs and their corresponding activation fields (used to store activation information of the positioning reference signal).

[0138] For another example, the first MAC CE may include identifiers of one or more TRPs and their corresponding activation fields (used to store activation information of the positioning reference signal).

[0139] In some implementations, the terminal device expects to receive the second information before the end of the second time period. Alternatively, the terminal device does not expect to receive the second information after the end of the second time period.

[0140] The second period mentioned above may be the same period as the first period mentioned above, or may be a different period from the first period. In some implementations, the start time of the second period is associated with the time when the first information is sent. For example, the start time of the second period is the same as the time when the first information is sent. The duration of the second period may be determined based on protocol predefined information and network device configuration information. Alternatively, the duration of the second period may be reported by the terminal device.

[0141] In some implementations, the second information is carried in the first MAC CE, and a transmission time of feedback information corresponding to the first MAC CE is earlier than an end time of the second time period.

[0142] In some implementations, after the first period ends, the terminal device enters an idle state, which can save power consumption.

[0143] In some implementations, if the second information is not received, the terminal device enters an idle state. When the terminal device enters the idle state, power consumption can be saved.

[0144] In some implementations, the terminal device sends third information to the network device. The third information is used to notify the network device that the terminal device is about to enter the idle state. The third information can be carried in the PRACH.

[0145] In some implementations, if the second information is not received, the terminal device sends third information to the network device. The third information is used to notify the network device that the terminal device is about to enter the idle state. The third information can be carried in the PRACH.

[0146] In some implementations, after the first period ends, if the time to TAT is still running, the terminal device continues uplink transmission. This is because during the TAT running period, the network device can still correct the time error by adjusting the TA.

[0147] In some implementations, if the second information is not received and the TAT is still running, the terminal device continues to perform uplink transmission.

[0148] In some implementations, after the first time period ends, if the location information of the terminal device is still in an invalid state, the terminal device performs downlink transmission instead of uplink transmission.

[0149] It should be noted that the embodiments of Figures 5 and 6 may include a capability reporting process of a terminal device. For example, the terminal device sends capability information to a network device, and the capability information is used to indicate that the terminal device supports a positioning method based on a positioning reference signal. The positioning reference signal can be sent by a base station or by a network element in the core network (such as a location management function (LMF)).
