Exactly speaking, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0183] First, the relevant concepts mentioned in this application are briefly described as follows.

[0184] 1. Satellite communication system

[0185] In satellite communication, there are two working modes:

[0186] One is the transparent relay mode. The satellite only transparently relays the signal without any processing. The terminal communicates with the gateway station. That is, the satellite only performs operations such as frequency conversion and radio signal amplification on the uplink / downlink signal. Its function is similar to that of a radio frequency relay.

[0187] In satellite communication, the connection between the terminal user and the satellite is called the user link, and the connection between the satellite and the gateway station is the feeder link.

[0188] The other is the regenerative communication mode. At this time, the satellite can detect the information of the received signal, process and forward it, and complete the function of the base station, connecting the terminal and the gateway station. That is, the satellite can perform functions such as frequency conversion, radio signal amplification, encoding / modulation, and demodulation / decoding on the uplink / downlink signal. That is to say, the satellite can have all or part of the functions of the gNB and can regenerate the signal.

[0189] Earth-Fixed cell: It means that within a certain period of time, the ground coverage area of the satellite's service cell does not change with the movement of the satellite. That is, in the staring mode, the satellite is moving, but within a certain period of time, the satellite is similar to staring at a certain area on the ground. For example, when the satellite moves from time T1 to time T2, the satellite's coverage area on the ground is always area A. Quasi-Earth Fixed cell means approximately (similar to) Earth-Fixed cell, which means that the satellite stares at the ground for a relatively short time, that is, the interval between T1 and T2 is relatively short. In this scenario, as the satellite moves, the angle between the satellite antenna and the ground changes, so as to ensure that the area covered by the satellite antenna remains unchanged.

[0190] Earth-moving cell: It means that the ground coverage area of the satellite's service cell changes with the movement of the satellite. The satellite's coverage area is A at time T1 and B at time T2. In this scenario, as the satellite moves, the angle between the satellite antenna and the ground hardly changes.

[0191] Whether in the above-mentioned transparent forwarding mode or the regeneration mode, whether in quasi-Earth-Fixed cells or Earth-moving cells, in a Non-Terrestrial Network (NTN), signals and data need to pass through at least a bent pipe propagation of UE-satellite-UE. Some may need to pass through a bent pipe propagation of UE-satellite-ground station-satellite-UE. The delay of the above-mentioned bent pipe propagation can range from more than ten milliseconds to dozens of milliseconds, or even up to hundreds of milliseconds, depending on the satellite orbit altitude. This is much greater than the propagation delay of a Terrestrial Network (TN). The long propagation delay of NTN will severely limit the applications that can be applied in NTN because the end-to-end propagation delay requirement may not be met.

[0192] Therefore, how to solve the propagation delay caused by using NTN is the current key concern.

[0193] The embodiments of the present application will be described below with reference to the accompanying drawings. The information transmission method, device, terminal, and network device provided by the embodiments of the present application can be applied to a wireless communication system. The wireless communication system can be a system using the 5th Generation (5G) mobile communication technology (hereinafter simply referred to as the 5G system). Those skilled in the art can understand that the 5G NR system is only an example and not a limitation.

[0194] See Figure 1 , Figure 1 is a structural diagram of a network system to which the embodiments of the present application can be applied. As Figure 1 shown, it includes a user terminal 11 and a base station 12. Among them, the user terminal 11 can be a User Equipment (UE). For example, it can be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a Mobile Internet Device (MID), or a wearable device, etc. terminal-side devices. It should be noted that the specific type of the user terminal 11 is not limited in the embodiments of the present application. The above-mentioned base station 12 can be a base station of 5G and later versions (for example: gNB, 5G NR NB), or a base station in other communication systems, or called a Node B. It should be noted that only a 5G base station is taken as an example in the embodiments of the present application, but the specific type of the base station 12 is not limited.

[0195] Embodiments of the present application provide an information transmission method, apparatus, terminal, and network device to reduce the communication delay of using non-terrestrial networks, improve the enthusiasm for using non-terrestrial networks in related applications, and increase the network utilization rate of non-terrestrial networks.

[0196] It should be noted that the above non-terrestrial network may include satellite networks, such as geostationary satellite networks, medium-earth orbit satellite networks, or low-earth orbit satellite networks, etc.; it may also include near-space networks, such as communication networks composed of airships, drones, hot air balloons, etc. carrying communication modules. The types of non-terrestrial networks are not limited in this application.

[0197] Among them, the method and the apparatus are based on the same inventive concept. Since the principles of the method and the apparatus for solving problems are similar, the implementation of the apparatus and the method can be referred to each other, and the repeated parts will not be elaborated.

[0198] As Figure 2 shown, embodiments of the present application provide an information transmission method, which is executed by a terminal and includes:

[0199] Step S201: Receive downlink information from a first network, where the downlink information includes at least one of the following: downlink channel, downlink signaling, downlink data, downlink signal;

[0200] It should be noted that the downlink channel may include but is not limited to at least one of the following: Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH).

[0201] Step S202: Send uplink information to a second network, where the uplink information includes at least one of the following: uplink channel, uplink signaling, uplink data, uplink signal;

[0202] It should be noted that the uplink channel may include but is not limited to at least one of the following: Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH).

[0203] Among them, one of the first network and the second network is a terrestrial network (TN), and the other is a non-terrestrial network (NTN).

[0204] It should be noted that by separately transmitting the uplink information and the downlink information from the NTN and the TN respectively, the communication delay using the NTN can be reduced, the enthusiasm for relevant applications to use the NTN can be increased, and the network utilization rate of the NTN can be improved.

[0205] It should be noted that there is no obvious sequential relationship between step 201 and step 202. The limitation of the above two steps is only to show that the uplink information and the downlink information are transmitted separately and independently. That is to say, in the embodiments of the present application, it is only limited that the uplink information and the downlink information are transmitted independently.

[0206] Here, it should be noted that the first network includes the first network device, and the second network includes the second network device; for example, when the first network is the NTN and the second network is the TN, the first network device can be an NTN network base station. For example, it includes a satellite, that is, a satellite capable of realizing the base station function, which can also be called a satellite base station. Or, in the NTN transparent transmission mode, the satellite only transparently transmits the signaling or data between the terminal and the ground base station supporting satellite communication. Then, the first network device is a ground-based base station supporting satellite communication (necessary forwarding is done between the terminal and the ground base station supporting the satellite through the satellite), and the second network device is a TN network base station; for example, when the first network is the TN and the second network is the NTN, the first network device can be a TN network base station, and the second network device is an NTN network base station. For example, it includes a satellite base station, or in the transparent transmission mode, the second network device can be a ground-based base station supporting satellite communication (necessary forwarding is done between the terminal and the ground base station supporting the satellite through the satellite).

[0207] Optionally, in the embodiments of the present application, receiving from the first network can be understood as receiving from the first network device corresponding to the first network, and the abbreviated expression is: receiving from the first network device; sending to the second network in the embodiments of the present application can be understood as sending to the second network device corresponding to the second network, and the abbreviated expression is: sending to the second network device.

[0208] It should be noted that for the NTN, its corresponding ground base station can share the same station with the ground base station of the TN, or can also not share the same station.

[0209] It should be noted that the embodiments of the present application mainly provide two implementation schemes for the uplink and the downlink, that is, completing access in the network (the first network or the second network) where the terminal camps, and then configuring the uplink and downlink separation; and, in the random access phase, starting to use the uplink and downlink separation method for information transmission. The following will separately describe these two implementation schemes in detail as follows.

[0210] Implementation Scheme 1: Completing access in the network (the first network or the second network) where the terminal camps, and then configuring the uplink and downlink separation

[0211] Optionally, in this case, the method further includes at least one of the following:

[0212] A11. Receiving first uplink configuration information and first downlink configuration information sent by a first network, where the first uplink configuration information is for a second network, and the first downlink configuration information is for the first network;

[0213] It should be noted that this case can be understood as the terminal camping on the first network and receiving relevant configurations of the first network and the second network from the first network.

[0214] Here, it should be noted that the first uplink configuration information and the first downlink configuration information may be sent by the first network to the terminal through different messages respectively, or may be sent by the first network to the terminal through the same message simultaneously or respectively. For example, the first network sends the first downlink configuration information and / or the first uplink configuration information to the terminal through a Radio Resource Control (RRC) reconfiguration message.

[0215] Optionally, in one implementation, the first uplink configuration information includes at least one of the following:

[0216] A111. Indication information of the second network;

[0217] It should be noted that the indication information is mainly used to indicate the cell under the second network.

[0218] A112. Uplink resources of the second network;

[0219] Optionally, the uplink resources include at least one of the following:

[0220] A1121. PUSCH resources;

[0221] A1122. PUCCH resources;

[0222] A1123. Resources related to the Sounding Reference Signal (SRS);

[0223] A1124. Resources related to the Scheduling Request (SR).

[0224] Optionally, in one implementation, the first downlink configuration information includes at least one of the following:

[0225] A113. Indication information of the first network;

[0226] It should be noted that the indication information is mainly used to indicate the cell under the first network.

[0227] A114, PDCCH configuration information.

[0228] A12. Receive the second uplink configuration information and the second downlink configuration information sent by the second network, where the second uplink configuration information is for the second network and the second downlink configuration information is for the first network;

[0229] It should be noted that this situation can be understood as the terminal camping on the second network and receiving the relevant configurations of the first network and the second network from the second network.

[0230] Here, it should be noted that the second uplink configuration information and the second downlink configuration information can be sent by the second network to the terminal through different messages respectively, or can be sent by the first network to the terminal through the same message simultaneously.

[0231] For example, the second network sends the second downlink configuration information to the terminal through an RRC reconfiguration message. Optionally, the second network can also update the second downlink configuration information of the first network according to the change of the cell of the first network (including the change of the cell of the first network and the change of the downlink configuration for uplink-downlink separation when the cell of the first network remains unchanged).

[0232] Optionally, in one implementation, the second uplink configuration information includes at least one of the following:

[0233] A121. Indication information of the second network;

[0234] It should be noted that the indication information is mainly used to indicate the cell under the second network.

[0235] A122. Uplink resources of the second network;

[0236] Optionally, the uplink resources include at least one of the following:

[0237] A1221. PUSCH resources;

[0238] A1222. PUCCH resources;

[0239] A1223. SRS-related resources;

[0240] A1224. SR-related resources.

[0241] Optionally, in one implementation, the second downlink configuration information includes at least one of the following:

[0242] A123. Indication information of the first network;

[0243] It should be noted that the indication information is mainly used to indicate the cell under the first network.

[0244] A124, PDCCH configuration information.

[0245] For example, taking the first network as NTN and the second network as TN, the above implementation is illustrated as follows:

[0246] Case 1: The terminal accesses from TN, configures NTN, and completes the uplink and downlink separation configuration

[0247] As Figure 3 shown, it mainly includes the following processes:

[0248] Step 31: The terminal camps on TN and completes the RRC connection establishment in TN;

[0249] Step 32: TN configures NTN for the terminal;

[0250] Step 33: NTN performs downlink scheduling, uplink authorization, and / or downlink transmission;

[0251] Step 34: The terminal performs uplink transmission or transmits the hybrid automatic repeat request (HARQ) result for the downlink transmission;

[0252] Step 35: The base station of TN sends the HARQ result for the downlink transmission to the base station of NTN.

[0253] Case 2: The terminal accesses from NTN, configures TN, and completes the uplink and downlink separation configuration

[0254] As Figure 4 shown, it mainly includes the following processes:

[0255] Step 41: The terminal camps on NTN and completes the RRC connection establishment in NTN;

[0256] Step 42: NTN configures TN for the terminal;

[0257] Step 43: NTN performs downlink scheduling, uplink authorization, and / or downlink transmission;

[0258] Step 44: The terminal performs uplink transmission or transmits the HARQ result for the downlink transmission;

[0259] Step 45: The base station of TN sends the HARQ result for the downlink transmission to the base station of NTN.

[0260] It should be noted that if the base station gNB1 of the NTN network and the base station gNB2 of the TN network share the same site, the inter-site interaction can be avoided, that is, the HARQ results do not need to be interacted between sites. For example, in the above case 1, the TN configures the NTN for the terminal, or in case 2, the NTN configures the TN for the terminal. If the base stations of the TN network and the NTN network share the same site (deployed together or integrated together), then the inter-site interaction can be avoided. This situation exists. For example, the base station of the TN network is upgraded to support the NTN network.

[0261] Implementation solution 2: In the random access phase, start using the uplink-downlink separation method for information transmission

[0262] Optionally, in this case, the sending of the uplink information to the second network includes:

[0263] Sending a random access preamble to the second network;

[0264] The receiving of the downlink information from the first network includes:

[0265] Receiving a random access response (RAR) from the first network.

[0266] It should be noted that this case refers to the terminal starting to perform uplink-downlink separation in the random access phase, that is, the uplink information in the random access process is sent to the second network, and the downlink information in the random access process is received from the first network.

[0267] It should be noted that the operations performed by the terminal are slightly different depending on the network it camps on. The following will separately elaborate on the specific implementations in different camping scenarios in detail as follows.

[0268] 1. The terminal camps on the second network

[0269] It should be noted that in this case, the method further includes:

[0270] Obtaining the system information of the first network from the second network or obtaining the system information of the first network from the first network.

[0271] That is to say, when the terminal camps on the second network, the terminal can directly obtain the system information of the second network from the second network. The system information of the first network can be obtained by the terminal from the first network or from the second network. In the case of obtaining the system information of the first network from the second network, the first network needs to send the system information to the second network first, that is, the first network device corresponding to the first network needs to send the system information to the second network device corresponding to the second network.

[0272] Optionally, the system information of the first network includes: PDCCH configuration information. Optionally, the PDCCH configuration information includes the PDCCH configuration information of the RAR of the first network.

[0273] It should be noted that the random access process in this case is mainly as follows:

[0274] The terminal obtains the RACH configuration by listening to the system information of the second network, and sends a preamble on the second network; the terminal receives the RAR by using the PDCCH configuration information required for the RACH process obtained from the system information of the first network obtained, so that the RRC connection establishment can be completed through the random access process.

[0275] For example, the terminal obtains the Physical Random Access Channel (PRACH) configuration from the second network and sends a preamble. Then the terminal needs to know the PDCCH configuration information of the RAR of the first network. Usually, this PDCCH configuration information is indicated by the system information. For example, the PDCCH configuration information is indicated by the random access search space (ra-SearchSpace) in the PDCCH configuration (PDCCH-ConfigCommon) in the bandwidth part (BWP) configuration (BWP-DownlinkCommon) in the downlink common configuration in the serving cell common configuration (ServingCellConfigCommonSIB) in the SIB in the System Information Block 1 (SIB1). Other PDCCH configuration information other than the PDCCH configuration information of the RAR of the first network can be sent by dedicated signaling.

[0276] Optionally, in this case, the manner in which the terminal continuously obtains the system information of the first network may include one of the following:

[0277] B11. The second network sends the system information of the first network. For example, a separate SIB (such as SIBx) is defined. The change of SIBx does not trigger a system information change indication because the second network remains unchanged while the cells of the first network on it are constantly changing. Therefore, SIBx changes with the change of the first network. The terminal reads SIBx when needed (such as when a random access needs to be initiated). SIBx may include the configuration information of the cells of the first network, such as frequency, Synchronization Signal Block (SSB) information, etc.

[0278] B12. If the terminal has been in downlink synchronization with the cell of the first network, that is, it can always obtain the Master Information Block (MIB), then the terminal can read the SIB1 of the first network when needed.

[0279] II. The terminal camps on the first network

[0280] It should be noted that in this case, the method further includes one of the following:

[0281] C11. Obtain the system information of the second network from the second network;

[0282] That is to say, when the terminal camps on the first network, it can directly obtain the system information of the second network from the second network.

[0283] Optionally, in one implementation, the specific method of obtaining the system information of the second network from the second network includes one of the following:

[0284] C111. Continuously receive the system information of the second network from the second network;

[0285] It should be noted that in this case, when the terminal camps on the first network, it can continuously receive the system information of the first network and update the system information as needed.

[0286] C112. Obtain the system information from the second network when the terminal needs to access the network;

[0287] It should be noted that "needs to access the network" means that the terminal needs to access the network, and the terminal can determine whether it needs to access the network by itself. For example, the terminal determines that it needs to access the network after making a call or listening to a paging message.

[0288] It should be noted that in this case, the terminal does not continuously receive the system information of the second network, but reads the system information of the second network when needed. Since the system information retained by the terminal is not the latest in real time, therefore, the embodiments of the present application provide a method for updating system information. Optionally, the method further includes:

[0289] Receive a system information update notification of the second network from the first network;

[0290] Update the system information of the second network according to the system information update notification.

[0291] That is to say, the terminal sends a system information update notification of the second network through the first network. For example, define a system information SIBy, which transmits the system information update notification of the second network under the cell of the first network. For example, define a cell list of the second network, which contains the information of one or more cells of the second network. The information of the cells of the second network is mainly the system information change indication information of the corresponding cells of the second network, indicating whether the system information has changed and which system information has changed (needs to be updated), etc. Optionally, if the number of cells of the first network in the first network is too large, the area can be divided. For example, area 1 contains cells 1, 2,..., m. If the system information of any cell of the second network in area 1 changes, it indicates that the system information of the cells of the second network in area 1 has changed, and the terminals in area 1 all re-obtain the system information of the cells of the second network where they are located.

[0292] It should be noted that in this case, the embodiment of the present application does not limit the first acquisition method of the system information of the second network. For example, when the terminal is camped on the first network, based on the implementation of the terminal, the system information of a cell of the second network can be obtained simultaneously.

[0293] It should be noted that the random access process in this case is mainly as follows:

[0294] If the terminal needs to access the network, it determines the random access resource according to the system information of the cell of the second network, and initiates random access in the second network, that is, sends a preamble to the second network. The second network receives the preamble sent by the terminal, and sends a RAR through the cell of the first network (if it is L1 / L2 mobility enhancement, it can be an LTM (L1L2 triggering mobility) command). The TA carried in the RAR is the TA of the cell of the second network. The RAR is generated by the second network, sent to the first network, and forwarded to the terminal through the first network. The terminal receives the RAR from the first network, completes the uplink synchronization according to the downlink synchronization of the cell of the second network maintained by itself and the TA in the RAR, and sends Msg3. The terminal continuously receives the scheduling of the cell of the second network from the first network, and sends uplink in the cell of the second network. While the terminal resides in the cell of the first network, the cell of the second network that it needs to monitor may change due to the movement of the terminal. Cell reselection will not be triggered here because the cell where the terminal resides is the cell of the first network. However, the system information of the new second network cell can be obtained (for example, based on the terminal implementation), and then the system information of the new first network cell can be maintained based on the above process. If the system information of the cell of the first network or the cell of the second network monitored by the terminal changes, the terminal needs to ensure that the valid system information of the first network is obtained before initiating network random access through the second network (for example, based on the terminal implementation). For example, the terminal can switch to the cell of the second network to receive the system information of the cell of the second network when it does not need to monitor the downlink signaling / downlink signal in the first network.

[0295] C12. Acquire system information of the second network from the first network;

[0296] This situation means that the first network first obtains the system information of the second network, and then sends the system information of the second network to the terminal. That is to say, the second network needs to send the system information to the first network first, and the first network then sends the system information of the second network to the terminal. That is, the second network device corresponding to the second network needs to send the system information to the first network device corresponding to the first network first, and the first network device corresponding to the first network then sends the system information of the second network to the terminal.

[0297] It should be noted that there is interaction between base stations during the implementation of Solution 2, so the timing relationship needs to change. For example, after the preamble is sent, the second network needs to send the RAR to the first network before the first network can send the RAR. Therefore, the start time of the RA window may need to be delayed. The first network delays by one round-trip time (RTT) of the first network. Here, it may not be necessary to delay for that long, only half of the RTT of the second network and half of the RTT of the first network. It should also be noted that the start of the timers related to HARQ also needs to be adjusted accordingly.

[0298] Optionally, if the NTN network base station gNB1 and the TN network base station gNB2 share the same site, the inter-site interaction can be avoided, that is, the system information of the first network or the second network does not need to be interacted between sites.

[0299] Optionally, regarding how the first network obtains the resources of the second network's cell, the second network's cell can reserve resources for the first network's scheduling, such as a carrier, one or more BWPs in a carrier, etc. The first network schedules according to its needs on these reserved resources. It should be noted that the above situation requires base station interaction. Similarly, if the terminal accesses through the second network and configures the resources of the first network through the second network, the second network's cell also needs to configure the resources of the first network's cell for the terminal. The first network's cell can also reserve resources, such as a carrier, one or more BWPs in a carrier, etc. Of course, it can also be some time-division resources, such as defining a time period during which the resources are used for the downlink transmission of the second network or the uplink transmission of the first network.

[0300] For example, taking the first network as NTN and the second network as TN, the above implementation is illustrated as follows:

[0301] Case 1: The terminal camps in TN (the terminal can directly perform TN downlink synchronization and system information reception) and initiates network access from TN: The terminal needs to obtain the relevant configuration of NTN from the camped TN so that the terminal can listen for PDCCH from NTN.

[0302] Optionally, the terminal obtains the PRACH configuration from the TN, sends a preamble, and then the terminal needs to know the PDCCH configuration information of the NTN's RAR. Usually, this PDCCH configuration information is indicated in SIB1 -> ServingCellConfigCommonSIB -> DownlinkConfigCommon -> BWP-DownlinkCommon -> PDCCH-ConfigCommon -> ra-SearchSpace. Therefore, the terminal only needs to obtain the SIB1 of the NTN cell. The subsequent other PDCCH configuration information is implemented through dedicated signaling.

[0303] The specific process is as follows: The terminal obtains the RACH configuration by listening to the system information of the TN and sends a preamble on the TN; the terminal obtains the PDCCH (on the NTN) configuration required for the RACH process by obtaining the SIB1 of the NTN, receives the RAR, and can complete the RRC connection establishment through the random access process.

[0304] Optionally, the terminal camps on the TN and can continuously obtain the SIB1 of the NTN in one of the following ways:

[0305] Method 1: The TN can send the SIB1 covering the NTN cells covered by the TN;

[0306] For example, define a separate SIBx. The change of this SIBx does not trigger a system information change indication because the TN remains unchanged while the NTN cells on it are constantly changing. Therefore, SIBx changes with the change of the NTN. When needed (such as when a random access needs to be initiated), the terminal reads SIBx. SIBx can contain the configuration information of the NTN cell, such as frequency, SSB information, etc.

[0307] Method 2: If the terminal has been in downlink synchronization with the NTN cell, that is, the terminal can always obtain the MIB of the NTN, then, when needed, the terminal can read the SIB1 of the NTN.

[0308] Case 2: The terminal camps on the NTN (the terminal can directly perform downlink synchronization and system information reception of the NTN) and initiates network access from the TN

[0309] Specifically, the terminal obtains the system information of the TN. The specific methods for obtaining the uplink and downlink synchronization of the TN include one of the following:

[0310] 1. The terminal can receive the system information of the TN from the NTN

[0311] It should be noted here that because there are too many TN cells under the NTN cell, if the system information of the TN cell is broadcast through the NTN, there will be a problem of too large system overhead.

[0312] 2. The terminal obtains the system information of the TN from the TN

[0313] Specifically, it includes one of the following methods:

[0314] Method 1: While camping on the NTN cell, continuously receive the system information of the TN cell and update the system information as needed.

[0315] Method 2: When it is necessary to access the network (for example, after making a call or listening to a paging message), receive the configuration of the TN network again

[0316] It should be noted that in this case, the terminal needs to obtain and maintain the system information of the TN. The method for the first acquisition of the system information of the TN is not limited in this application. For example, when camping on the NTN, the terminal can obtain the system information of a TN cell at the same time (for example, based on the terminal implementation). Specifically, the method for maintaining the system information is as follows:

[0317] The NTN sends a system information update notification of the TN, and the terminal updates the system information of the TN based on this system information update notification.

[0318] For example, define a system information SIBy, which transmits the system information update notification of the TN under the NTN cell. For example, define a TN cell list, which contains the information of one or more TN cells. The information of the TN cell is mainly the system information change indication information of the corresponding TN cell, indicating whether the system information has changed and which system information has changed (needs to be updated), etc. Optionally, if the number of TN cells in the NTN is too large, the area can be divided. For example, area 1 contains TN1, TN2,..., TNm. If the system information of any TN cell in area 1 changes, it indicates that the system information of the TN in area 1 has changed, and the terminals in area 1 all re-obtain the system information of their respective TN cells.

[0319] The specific random access process is mainly as follows:

[0320] If the terminal needs to access the network, it determines the random access resources according to the system information of the TN cell and initiates random access in the TN cell. When the TN cell receives the preamble sent by the terminal, it sends an RAR (if it is L1 / L2 mobility enhancement, it can be an LTM command) through the NTN cell. The TA carried in the RAR is the TA of the TN cell. It should be noted that the RAR is generated by the TN, sent to the NTN, and forwarded to the terminal by the NTN. The terminal receives the RAR from the NTN cell, completes the uplink synchronization based on the downlink synchronization of the TN cell it maintains and the TA in the RAR, and sends Msg3. The terminal continuously receives the scheduling of the TN cell from the NTN and sends uplink data in the TN cell.

[0321] Optionally, for the security anchor point, that is, whether the encryption of data or signaling is performed at the NTN base station or the TN base station. For example, security operations can be completed at the TN network node, and the secure data packet (such as the Packet Data Convergence Protocol (PDCP)) is sent to the NTN base station and then sent to the terminal by the NTN base station.

[0322] It should be noted that in at least one embodiment of the present application, the uplink and downlink separation of a service greatly reduces the propagation delay and improves the participation rate of the NTN in supporting services; through this mechanism, the enthusiasm of the UE to use the NTN can be improved, and the utilization rate of the NTN system can be increased.

[0323] The technical solutions provided by the embodiments of the present application can be applicable to various systems, especially 5G systems. For example, the applicable systems can be Global System of Mobile Communication (GSM) systems, Code Division Multiple Access (CDMA) systems, Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS) systems, Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Long Term Evolution Advanced (LTE-A) systems, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) systems, 5G New Radio (NR) systems, etc. Both terminals (which can also be referred to as terminal devices) and network devices are included in these various systems. The core network part can also be included in the system, such as Evolved Packet System (EPS), 5G System (5GS), etc.

[0324] The terminal involved in the embodiments of the present application, which can also be referred to as a terminal device, can be a device that provides voice and / or data connectivity to users, such as a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem, etc. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device can be called a user equipment (UE). The wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted mobile device that exchanges voice and / or data with the radio access network. For example, devices such as personal communication service (PCS) phones, cordless phones, session initiated protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), etc. The wireless terminal device can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, which is not limited in the embodiments of the present application.

[0325] The network device involved in the embodiments of the present application may be a base station, which may include multiple cells that provide services to terminals. Depending on the specific application scenarios, the base station may also be referred to as an access point, or may be a device in the access network that communicates with wireless terminal devices through one or more sectors over the air interface, or other names. The network device can be used to mutually replace the received air frames and Internet Protocol (IP) packets, and act as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the management of the attributes of the air interface.

In some network architectures, the network device may include a centralized unit (centralized unit, CU) node and a distributed unit (distributed unit, DU) node, and the centralized unit and the distributed unit may also be geographically separated.

[0326] A network device and a terminal device can each use one or more antennas for multi-input multi-output (MIMO) transmission. The MIMO transmission can be single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). According to the form and number of antenna combinations, the MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, or it can also be diversity transmission, precoding transmission, beamforming transmission, etc.

[0327] As Figure 5 shown, an embodiment of the present application provides an information transmission method, which is executed by a first network device and includes:
