[0095] 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 cellular mobile communication technology. The wireless communication system may include: a number of terminals 11 and a number of base stations 12.

[0096] Terminal 11 can be a device that provides voice and / or data connectivity to a user. Terminal 11 can communicate with one or more core network devices via a Radio Access Network (RAN). Terminal 11 can be an Internet of Things (IoT) terminal, such as a sensor device, a mobile phone (or "cellular" phone), or a computer with an IoT terminal. For example, it can 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, or user equipment (UE). Alternatively, Terminal 11 can also be a device from an unmanned aerial vehicle (UAV). Alternatively, Terminal 11 can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, terminal 11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0097] Base station 12 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 a 5G NR system. Alternatively, it can be a next-generation system after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.

[0098] In this embodiment, base station 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, base station 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When base station 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DU). The central unit is equipped with a protocol stack of Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), and Media Access Control (MAC) layers; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of base station 12.

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.

Network management device 13 can be a core network device in a wireless communication system, such as the 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 13 is not limited in this embodiment.

[0103] 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.

[0104] In Internet of Things (IoT) / Machine Type Communication (MTC) Non-terrestrial Network (NTN) systems, the UE needs to frequently receive GNSS signals to determine its location information, which is used to determine timing advance (TA) during communication. Due to UE capability limitations, the UE cannot simultaneously perform cellular network operation and GNSS signal reception. Furthermore, for GNSS signal reception, the UE may activate the GNSS module via a warm start or a cold start. If the UE activates the GNSS module via a warm start, it can complete GNSS signal reception in a short time, such as 1 or 2 seconds. If the UE activates the GNSS module via a cold start, it needs to gradually activate the components within the GNSS module, which may take a longer time to complete GNSS signal reception, such as 1 or 2 minutes. The UE cannot perform cellular network operation while receiving GNSS signals.

[0105] Therefore, how to coordinate the reception of GNSS signals and the communication of cellular networks to improve the communication stability of UEs, given the different GNSS module activation methods during UE GNSS signal reception, is an urgent problem to be solved.

[0106] like Figure 2 As shown, this exemplary embodiment provides an information transmission method that can be executed by a UE, including:

[0107] Step 201: Send UE capability information to the network-side device. The capability information is used to indicate the method by which the UE receives GNSS signals. The capability information is used by the network-side device to determine first configuration information, which is used by the UE to receive GNSS signals.

[0108] In one possible implementation, the network-side equipment includes, but is not limited to, at least one of the following: access network equipment such as base stations; and wired network equipment.

[0109] In one possible implementation, the network-side device can be a network-side device of the NTN network.

[0110] In one possible implementation, the UE includes, but is not limited to, at least one of the following: a UE that communicates via an NTN network, or a UE that communicates via a terrestrial network.

[0111] For example, the UE is a UE that communicates over an NTN network. Because the positions of the UE and the satellite are constantly changing, the UE needs to frequently determine its position in order to determine the TA during communication.

[0112] In one possible implementation, GNSS signals include, but are not limited to, positioning signals based on satellite positioning.

[0113] Network-side devices can receive capability information sent by the UE while maintaining a connection with the UE.

[0114] In one possible implementation, capability information is carried in the RRC message.

[0115] In RRC connected mode, the UE can send capability information to the network-side equipment.

[0116] The way a UE receives GNSS signals can be predetermined or can change according to the actual state of the UE.

[0117] In one possible implementation, the time required for the UE to receive GNSS signals varies depending on the method used.

[0118] For example, the UE may receive GNSS signals in a manner including but not limited to at least one of the following: the UE cold-starts the GNSS module and receives the GNSS signals; the UE warm-starts the GNSS module and receives the GNSS signals.

[0119] After receiving the capability information, the network-side equipment can determine the first configuration information for the UE to receive GNSS signals based on the way the UE receives GNSS signals.

[0120] In one possible implementation, the first configuration information is used to indicate, but is not limited to, the resource configuration for the UE to receive GNSS signals.

[0121] For example, the first configuration information can be associated with the gap in GNSS reception by the UE. During the gap, the UE only receives GNSS signals and does not perform any mobile cellular network-related operations; that is, the UE does not need to perform signal reception / transmission operations on the serving cell.

[0122] Thus, through capability information, the UE can indicate to the network-side device the method it uses to receive GNSS information, and the network-side device can determine the method the UE uses to receive GNSS signals. This allows the network-side device to determine the UE's status and reduces configuration errors caused by the network-side device's uncertainty about the UE's GNSS signal reception method. Based on the first configuration information, the UE can receive GNSS information. Since the first configuration information is set based on capability information, the UE's GNSS signal reception requirements can be configured. On the one hand, this improves the accuracy of the network-side device's configuration of the first configuration information and reduces resource waste. On the other hand, it increases the success rate of the UE receiving GNSS signals, thereby improving the positioning success rate.

[0123] In one embodiment, the UE receives the GNSS signal in two ways: a first method and a second method, wherein the first duration required for the UE to receive the GNSS signal using the first method is less than the second duration required for the UE to receive the GNSS signal using the second method.

[0124] Here, the UE can receive GNSS signals using at least two methods. Furthermore, the time required for receiving GNSS signals using the two methods differs. The UE can indicate the method used to the network-side equipment through capability information.

[0125] In one possible implementation, the first duration required to receive the GNSS signal via the first method or the second duration required to receive the GNSS signal via the second method can be predetermined or pre-agreed upon. The first duration corresponding to the first method and / or the second duration corresponding to the second method can be pre-agreed upon or determined by a communication protocol, etc.

[0126] In this way, by using capability information, network-side devices can determine whether the UE uses the first or second method to receive GNSS signals, thereby determining the duration required to receive GNSS, improving the accuracy of configuring the first configuration information, and increasing the success rate of UE positioning via GNSS information.

[0127] In one embodiment, the first configuration information includes at least one of the following:

[0128] The duration of the interval between receiving the GNSS signal;

[0129] The period of the gap;

[0130] The offset of the gap.

[0131] After receiving the capability information, the network-side equipment can determine the first configuration information for the UE to receive GNSS signals based on the way the UE receives GNSS signals, i.e., by using either the first or the second method.

[0132] The first configuration information is associated with the gap in GNSS reception by the UE. During the gap, the UE only receives GNSS signals and does not perform any mobile cellular network-related operations; that is, the UE does not need to perform signal reception / transmission operations on the serving cell.

[0133] In one possible implementation, if the UE receives GNSS signals using the first method, the interval duration is longer than the first duration. If the UE receives GNSS signals using the second method, the interval duration is longer than the second duration.

[0134] For example, if the network-side device determines that the UE is receiving GNSS signals using a first method, then the network-side device can configure a shorter interval duration. If the network-side device determines that the UE is receiving GNSS signals using a second method, then the network-side device can configure a longer interval duration.

[0135] In one possible implementation, the network-side device can determine the time slot period, the time slot offset, etc., based on the configured time slot duration.

[0136] In one possible implementation, the gap offset can be an offset from the gap start position.

[0137] For example, for gaps with longer durations, the network-side device can configure a longer time slot period for the UE.

[0138] In this way, by using capability information, network-side devices can determine the corresponding time slot configuration based on the way the UE receives GNSS signals, so that the time slot configuration can meet the needs of different GNSS signal reception methods, thereby enabling positioning based on GNSS signals.

[0139] In one embodiment, the duration of the gap is greater than or equal to the duration required for the UE to receive the GNSS signal in the manner indicated by the capability information;

[0140] And / or, the period of the gap is the GNSS update period.

[0141] The UE needs to complete the reception of GNSS signals within the time interval configured by the network-side equipment. Therefore, the time interval needs to be greater than or equal to the time required for the UE to receive GNSS signals.

[0142] Network-side equipment can configure the gap period based on the required GNSS update cycle, thereby meeting the GNSS update cycle's requirements for location information.

[0143] Here, the GNSS update cycle may include the update cycle of the UE location information.

[0144] In one embodiment, the UE receives the GNSS signal using a first method, including: the UE hot-starts the GNSS module and receives the GNSS signal;

[0145] The UE uses a second method to receive GNSS signals, including: the UE cold-starts the GNSS module and receives the GNSS signals.

[0146] like Figure 3 As shown, this exemplary embodiment provides an information transmission method that can be executed by a UE, including:

[0147] Step 301: Receive the first configuration information sent by the network-side device.

[0148] In one possible implementation, the first configuration information can be carried in an RRC message and sent to the UE by the network-side device.

[0149] For example, the network-side device configures the UE's gap configuration information (first configuration information) when receiving GNSS signals via RRC messages. The first configuration information indicates at least one of the following: gap duration (T); gap repetition period (Gap_Period); and gap offset. During the gap period, the UE only receives GNSS signals and does not perform any cellular-related operations; that is, the UE does not need to perform reception / transmission operations on the serving cell. T should be greater than or equal to the time corresponding to type 1 or type 2, and Gap_Period should be the GNSS update period.

[0150] like Figure 4 As shown, this exemplary embodiment provides an information transmission method that can be executed by a UE, including:

[0151] Step 401: When the UE's capability information indicates that the UE adopts the second method, the second configuration information is sent by the network-side device. The second configuration information is used by the UE to start the RRC reconstruction process or initiate initial access.

[0152] If the UE uses the second method to receive the GNSS signal, such as using a cold-start GNSS module, the second time required for the UE to receive the GNSS signal is relatively long. The UE may lose synchronization with the serving cell, or, in an NTN scenario, the UE may leave the serving cell due to satellite movement. Therefore, the network-side equipment can send second configuration information to the UE for UE access to the target cell. The second configuration information may include at least the information necessary for UE access to the target cell, such as: the target cell identifier; the target cell frequency band information, etc.

[0153] In one possible implementation, the network-side device can send the second configuration information to the UE before the UE receives the GNSS signal in the time slot.

[0154] The UE initiates an initial access procedure to access the target cell based on the second configuration information.

[0155] In one possible implementation, the second configuration information can be carried in the RRC message sent by the network-side device to the UE.

[0156] In one possible implementation, after the UE receives the GNSS signal in a time slot, if the time slot is too long and the UE loses synchronization with the serving cell, the UE can initiate an RRC reconstruction process to re-establish an RRC connection with the serving cell.

[0157] This can reduce the number of cases where a UE is unable to access the cell after receiving GNSS signals.

[0158] In one embodiment, the second configuration information is sent by the network-side device when it determines that the UE uses the second method to receive the GNSS signal and that the UE leaves its current serving cell after a gap in receiving the GNSS signal.

[0159] When a UE is in an NTN network scenario, the relative position between the UE and the serving cell (including static, semi-static, and / or dynamic cells) may change as the satellite and / or the UE moves, causing the UE to leave the serving cell. The network-side equipment can pre-determine whether the UE will leave the current serving cell after receiving GNSS signals based on the relative motion state between the UE and the serving cell, and then determine whether to send second configuration information to the UE.

[0160] For example, if the network-side device determines that it will use the cold start GNSS module to receive GNSS signals, and determines that the UE may leave the signal coverage area of ​​the current serving cell after completing the GNSS signal reception based on the UE serving cell and the relative movement of the UE, the network-side device may send second configuration information to the UE.

[0161] like Figure 5 As shown, this exemplary embodiment provides an information transmission method, which can be executed by a network-side device, including:

[0162] Step 501: Receive capability information sent by the UE, the capability information being used to indicate the way the UE receives GNSS signals.

[0163] In one possible implementation, the network-side equipment includes, but is not limited to, at least one of the following: access network equipment such as base stations; and wired network equipment.

[0164] In one possible implementation, the network-side device can be a network-side device of the NTN network.

[0165] In one possible implementation, the UE includes, but is not limited to, at least one of the following: a UE that communicates via an NTN network, or a UE that communicates via a terrestrial network.

[0166] For example, the UE is a UE that communicates over an NTN network. Because the positions of the UE and the satellite are constantly changing, the UE needs to frequently determine its position in order to determine the TA during communication.

[0167] In one possible implementation, GNSS signals include, but are not limited to, positioning signals based on satellite positioning.

[0168] Network-side devices can receive capability information sent by the UE while maintaining a connection with the UE.

[0169] In one possible implementation, capability information is carried in the RRC message.

[0170] In RRC connected mode, the UE can send capability information to the network-side equipment.

[0171] The way a UE receives GNSS signals can be predetermined or can change according to the actual state of the UE.

[0172] In one possible implementation, the time required for the UE to receive GNSS signals varies depending on the method used.

[0173] For example, the UE may receive GNSS signals in a manner including but not limited to at least one of the following: the UE cold-starts the GNSS module and receives the GNSS signals; the UE warm-starts the GNSS module and receives the GNSS signals.

[0174] In this way, by using capability information, network-side devices can determine how the UE receives GNSS, reducing misjudgments caused by the network-side devices not knowing how the UE receives GNSS.

[0175] like Figure 6 As shown, this exemplary embodiment provides an information transmission method, which can be executed by a network-side device, including:

[0176] Step 601: Determine first configuration information based on the capability information, wherein the first configuration information is used for the UE to receive GNSS signals.

[0177] After receiving the capability information, the network-side equipment can determine the first configuration information for the UE to receive GNSS signals based on the way the UE receives GNSS signals.

[0178] In one possible implementation, the first configuration information is used to indicate, but is not limited to, the resource configuration for the UE to receive GNSS signals.

[0179] For example, the first configuration information can be associated with the gap in GNSS reception by the UE. During the gap, the UE only receives GNSS signals and does not perform any mobile cellular network-related operations; that is, the UE does not need to perform signal reception / transmission operations on the serving cell.

[0180] Thus, through capability information, the UE can indicate to the network-side device the method it uses to receive GNSS information, and the network-side device can determine the method the UE uses to receive GNSS signals. This allows the network-side device to determine the UE's status and reduces configuration errors caused by the network-side device's uncertainty about the UE's GNSS signal reception method. Based on the first configuration information, the UE can receive GNSS information. Since the first configuration information is set based on capability information, the UE's GNSS signal reception requirements can be configured. On the one hand, this improves the accuracy of the network-side device's configuration of the first configuration information and reduces resource waste. On the other hand, it increases the success rate of the UE receiving GNSS signals, thereby improving the positioning success rate.

[0181] In one embodiment, the UE receives the GNSS signal in two ways: a first method and a second method, wherein the first duration required for the UE to receive the GNSS signal using the first method is less than the second duration required for the UE to receive the GNSS signal using the second method.

[0182] Here, the UE can receive GNSS signals using at least two methods. Furthermore, the time required for receiving GNSS signals using the two methods differs. The UE can indicate the method used to the network-side equipment through capability information.

[0183] In one possible implementation, the first duration required to receive the GNSS signal via the first method or the second duration required to receive the GNSS signal via the second method can be predetermined or pre-agreed upon. The first duration corresponding to the first method and / or the second duration corresponding to the second method can be pre-agreed upon or determined by a communication protocol, etc.

[0184] In this way, by using capability information, network-side devices can determine whether the UE uses the first or second method to receive GNSS signals, thereby determining the duration required to receive GNSS, improving the accuracy of configuring the first configuration information, and increasing the success rate of UE positioning via GNSS information.

[0185] In one embodiment, the first configuration information includes at least one of the following:

[0186] The duration of the interval between receiving the GNSS signal;

[0187] The period of the gap;

[0188] The offset of the gap.

[0189] After receiving the capability information, the network-side equipment can determine the first configuration information for the UE to receive GNSS signals based on the way the UE receives GNSS signals, i.e., by using either the first method or the second method.

[0190] The first configuration information is associated with the gap in GNSS reception by the UE. During the gap, the UE only receives GNSS signals and does not perform any mobile cellular network-related operations; that is, the UE does not need to perform signal reception / transmission operations on the serving cell.

[0191] In one possible implementation, if the UE receives GNSS signals using the first method, the interval duration is longer than the first duration. If the UE receives GNSS signals using the second method, the interval duration is longer than the second duration.

[0192] For example, if the network-side device determines that the UE is receiving GNSS signals using a first method, then the network-side device can configure a shorter interval duration. If the network-side device determines that the UE is receiving GNSS signals using a second method, then the network-side device can configure a longer interval duration.

[0193] In one possible implementation, the network-side device can determine the time slot period, the time slot offset, etc., based on the configured time slot duration.

[0194] In one possible implementation, the gap offset can be an offset from the gap's starting position.

[0195] For example, for gaps with longer durations, the network-side device can configure a longer time slot period for the UE.

[0196] In this way, by using capability information, network-side devices can determine the corresponding time slot configuration based on the way the UE receives GNSS signals, so that the time slot configuration can meet the needs of different GNSS signal reception methods, thereby enabling positioning based on GNSS signals.

[0197] In one embodiment, the duration of the gap is greater than or equal to the duration required for the UE to receive the GNSS signal in the manner indicated by the capability information;

[0198] And / or, the period of the gap is the GNSS update period.

[0199] The UE needs to complete the reception of GNSS signals within the time interval configured by the network-side equipment. Therefore, the time interval needs to be greater than or equal to the time required for the UE to receive GNSS signals.

[0200] Network-side equipment can configure the gap period based on the required GNSS update cycle, thereby meeting the GNSS update cycle's requirements for location information.

[0201] Here, the GNSS update cycle may include the update cycle of the UE location information.

[0202] In one embodiment, the UE receives the GNSS signal using a first method, including: the UE hot-starts the GNSS module and receives the GNSS signal;

[0203] The UE uses a second method to receive GNSS signals, including: the UE cold-starts the GNSS module and receives the GNSS signals.

[0204] A cold start to a GNSS module may include, but is not limited to, at least one of the following: powering the GNSS module back on; reconfiguring the GNSS module; or resetting the GNSS module.

[0205] A warm restart of a GNSS module may include, but is not limited to, at least one of the following: reactivating a configured GNSS module; or waking up a dormant GNSS module.

[0206] The time required for a cold start of the GNSS module is longer than the time required for a warm start. Therefore, the first time for the UE to warm start the GNSS module and receive GNSS signals is shorter than the second time for cold start the GNSS module and receive GNSS signals.

[0207] Capability information can be carried in different RRC fields.

[0208] For example, the information element (IE): NTN-Parameters-NB can include indication information (capability information) regarding the UE's supported GNSS signal reception method type. If the indication message is "Type 1", it indicates that the UE can warm-start the GNSS module to receive GNSS signals, and the network-side device can determine that the UE can complete GNSS signal reception in a short time, such as 1 second or 2 seconds. If the indication message is "Type 2", it indicates that the UE can cold-start the GNSS module to receive GNSS signals, and the network-side device can determine that the UE needs a longer time to complete GNSS signal reception, such as 1 minute or 2 minutes.

[0209] For example, the IE:NTN-Parameters section includes indication information (capability information) regarding the UE's supported GNSS signal reception methods. If the indication message is "type 1," it means the UE can warm-start the GNSS module to receive GNSS signals, and the network-side device can determine that the UE can complete GNSS signal reception in a short time, such as 1 or 2 seconds. If the indication message is "type 2," it means the network-side device can determine that the UE can cold-start the GNSS module to receive GNSS signals, and the UE needs a longer time to complete GNSS signal reception, such as 1 or 2 minutes.

[0210] In this way, by using capability information, the network-side equipment can determine the method used by the UE to receive GNSS signals, i.e., whether the GNSS module is cold-started or warm-started, and configure the first configuration information, such as the interval duration, based on the cold-start or warm-start GNSS module configuration. On the one hand, this can improve the accuracy of the network-side equipment in configuring the first configuration information and reduce resource waste. On the other hand, it can improve the success rate of the UE receiving GNSS signals, thereby improving the positioning success rate.

[0211] like Figure 7 As shown, this exemplary embodiment provides an information transmission method, which can be executed by a network-side device, including:

[0212] Step 701: Send the first configuration information to the UE.

[0213] In one possible implementation, the first configuration information can be carried in an RRC message and sent to the UE by the network-side device.

[0214] For example, the network-side device configures the UE's gap configuration information (first configuration information) when receiving GNSS signals via RRC messages. The first configuration information indicates at least one of the following: gap duration (T); gap repetition period (Gap_Period); and gap offset. During the gap period, the UE only receives GNSS signals and does not perform any cellular-related operations; that is, the UE does not need to perform reception / transmission operations on the serving cell. T should be greater than or equal to the time corresponding to type 1 or type 2, and Gap_Period should be the GNSS update period.

[0215] like Figure 8 As shown, this exemplary embodiment provides an information transmission method, which can be executed by a network-side device, including:

[0216] Step 801: When the UE's capability information indicates that the UE adopts the second method, send the second configuration information to the UE. The second configuration information is used by the UE to start the RRC reconstruction process or initiate initial access.

[0217] If the UE uses the second method to receive the GNSS signal, such as using a cold-start GNSS module, the second time required for the UE to receive the GNSS signal is relatively long. The UE may lose synchronization with the serving cell, or, in an NTN scenario, the UE may leave the serving cell due to satellite movement. Therefore, the network-side equipment can send second configuration information to the UE for UE access to the target cell. The second configuration information may include at least the information necessary for UE access to the target cell, such as: the target cell identifier; the target cell frequency band information, etc.

[0218] In one possible implementation, the network-side device can send the second configuration information to the UE before the UE receives the GNSS signal in the time slot.

[0219] The UE initiates an initial access procedure to access the target cell based on the second configuration information.

[0220] In one possible implementation, the second configuration information can be carried in the RRC message sent by the network-side device to the UE.

[0221] In one possible implementation, after the UE receives the GNSS signal in a time slot, if the time slot is too long and the UE loses synchronization with the serving cell, the UE can initiate an RRC reconstruction process to re-establish an RRC connection with the serving cell.

[0222] This can reduce the number of cases where a UE is unable to access the cell after receiving GNSS signals.

[0223] In one embodiment, the second configuration information is sent by the network-side device when it determines that the UE uses the second method to receive the GNSS signal and that the UE leaves its current serving cell after a gap in receiving the GNSS signal.

[0224] When a UE is in an NTN network scenario, the relative position between the UE and the serving cell (including static, semi-static, and / or dynamic cells) may change as the satellite and / or the UE moves, causing the UE to leave the serving cell. The network-side equipment can pre-determine whether the UE will leave the current serving cell after receiving GNSS signals based on the relative motion state between the UE and the serving cell, and then determine whether to send second configuration information to the UE.

[0225] For example, if the network-side device determines that it will use the cold start GNSS module to receive GNSS signals, and determines that the UE may leave the signal coverage area of ​​the current serving cell after completing the GNSS signal reception based on the UE serving cell and the relative movement of the UE, the network-side device may send second configuration information to the UE.

[0226] The following provides a specific example in conjunction with any of the above embodiments:

[0227] 1. Introduce UE capability indication information (first mode), and indicate to the network via RRC message the UE's mode of receiving GNSS signals (i.e., indicating the first mode or the second mode);

[0228] For example, the information element (IE): NTN-Parameters-NB can include indication information (capability information) of the UE's supported GNSS signal reception method type. If the indication message is "Type 1" (first method), indicating that the UE can warm-start the GNSS module to receive GNSS signals, the network-side device can determine that the UE can complete GNSS signal reception in a short time, for example, 1 second or 2 seconds. If the indication message is "Type 2" (second method), indicating that the UE can cold-start the GNSS module to receive GNSS signals, the network-side device can determine that the UE needs a longer time to complete GNSS signal reception, for example, 1 minute or 2 minutes.

[0229] For example, the IE:NTN-Parameters section includes indication information (capability information) regarding the UE's supported GNSS signal reception methods. If the indication message is "type 1" (first method), it indicates that the UE can warm-start the GNSS module to receive GNSS signals, meaning the network-side device can determine that the UE can complete GNSS signal reception in a short time, such as 1 or 2 seconds. If the indication message is "type 2" (second method), it indicates that the network-side device can determine that the UE can cold-start the GNSS module to receive GNSS signals, meaning the UE needs a longer time to complete GNSS signal reception, such as 1 or 2 minutes.

[0230] 2. Based on the capability indication information reported by the UE, the network configures the corresponding gap configuration information to the UE;

[0231] For example, the network-side device configures the UE's gap configuration information (indicating the first configuration information) when receiving GNSS signals via an RRC message. The configuration information includes at least one of the following: gap duration (T); gap repetition period (Gap_Period); and gap start position (offset). During the gap period, the UE only receives GNSS signals and does not perform any cellular-related operations; that is, the UE does not need to perform reception / transmission operations on the serving cell. T should be greater than or equal to the time corresponding to type 1 or type 2, and Gap_Period should be the GNSS update period.

[0232] 3. If the UE reports "type 2" capability indication information, configure the corresponding target cell configuration to the UE if necessary, depending on the NTN network type;

[0233] For example, if the NTN network type is earth-fixed, after the UE completes GNSS reception, due to the long gap time, the UE loses synchronization with the serving cell, and the UE initiates the RRC reconstruction process.

[0234] For example, if the NTN network type is earth-fixed, the network configures the target cell configuration (second configuration information) of the target cell through RRC messages, and the UE initiates the initial access procedure to access the target cell based on the target cell configuration information.

[0235] like Figure 9 As shown, this exemplary embodiment provides an information transmission device 100, which is disposed in a user equipment (UE) and includes:

[0236] The transceiver module 110 is configured to send UE capability information to the network-side device.

[0237] In one embodiment, the first configuration information includes at least one of the following:

[0241] In one embodiment, the duration of the gap is greater than or equal to the duration required for the UE to receive the GNSS signal in the manner indicated by the capability information;

[0242] And / or, the period of the gap is the GNSS update period.

[0246] In one embodiment, the UE receives the GNSS signal using a first method, including: the UE hot-starts the GNSS module and receives the GNSS signal;

[0247] The UE uses a second method to receive GNSS signals, including: the UE cold-starts the GNSS module and receives the GNSS signals.

[0248] In one embodiment, the transceiver module 110 is further configured to:

[0249] When the UE's capability information indicates that the UE adopts the second method, the UE receives second configuration information sent by the network-side device. The second configuration information is used by the UE to start the RRC reconstruction process or initiate initial access.

[0250] In one embodiment, the second configuration information is sent by the network-side device when it determines that the UE uses the second method to receive the GNSS signal and that the UE leaves its current serving cell after a gap in receiving the GNSS signal.

[0251] like Figure 10 As shown, this exemplary embodiment provides an information transmission device 200, which, disposed in a network-side device, includes:

[0255] In one embodiment, the first configuration information includes at least one of the following:

[0256] The duration of the interval between receiving the GNSS signal;

[0257] The period of the gap;

[0258] The offset of the gap.

[0259] In one embodiment, the duration of the gap is greater than or equal to the duration required for the UE to receive the GNSS signal in the manner indicated by the capability information;

[0260] And / or, the period of the gap is the GNSS update period.

[0261] In one embodiment, the transceiver module 210 is further configured to:

[0262] The first configuration information is sent to the UE.

[0263] In one embodiment, the UE receives the GNSS signal in two ways: a first method and a second method, wherein the first duration required for the UE to receive the GNSS signal using the first method is less than the second duration required for the UE to receive the GNSS signal using the second method.

[0264] In one embodiment, the UE receives the GNSS signal using a first method, including: the UE hot-starts the GNSS module and receives the GNSS signal;

[0267] In one embodiment, the second configuration information is sent by the network-side device when it determines that the UE uses the second method to receive the GNSS signal and that the UE leaves its current serving cell after a gap in receiving the GNSS signal.
