[0058] In the above embodiments, the terminal can determine whether it supports uplink synchronization adjustment based on third information by comparing the duration of the second time with the duration of the first time. When it is determined that the duration of the second time is greater than or equal to the duration of the first time, it is determined that the terminal supports uplink synchronization adjustment based on third information.

The CU-DU structure can separate the protocol layer of the access network device. Some protocol layer functions are centrally controlled by the CU, while the remaining part or all protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0180] In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices, each comprising all or part of the aforementioned one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in this disclosure are also applicable to similar technical problems.

[0182] The following embodiments of this disclosure can be applied to Figure 1a The communication system 100 shown, or a part thereof, but not limited to it. Figure 1a The entities shown are illustrative; a communication system may include...

[0183] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Futuregeneration radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0184] The emergence of new internet applications such as Augmented Reality (AR), Virtual Reality (VR), and vehicle-to-vehicle communication has placed higher demands on wireless communication technologies, driving their continuous evolution to meet application needs. Cellular mobile communication technology is currently in a next-generation evolution phase. A key characteristic of this next-generation technology is its ability to support flexible configuration for multiple service types. Different service types have different requirements for wireless communication technologies. For example, Enhanced Mobile Broadband (eMBB) services primarily require high bandwidth and high speed; Ultra-reliable and Low Latency Communications (URLLC) services primarily require high reliability and low latency; and Massive Machine Type Communication (mMTC) services primarily require a large number of connections. Therefore, next-generation wireless communication systems need flexible and configurable designs to support the transmission of multiple service types.

[0185] In the research of wireless communication technology, satellite communication is considered an important aspect of the future development of wireless communication technology. Satellite communication refers to communication conducted by terrestrial radio communication equipment using satellites as relays. A satellite communication system consists of a satellite component and a terrestrial component. The characteristics of satellite communication are: large communication range; communication can be conducted between any two points within the coverage area of ​​the satellite's emitted radio waves; and it is less affected by land-based disasters (high reliability). As a supplement to current terrestrial cellular communication systems, satellite communication offers the following advantages: Extended coverage: For areas where current cellular communication systems cannot cover or have high coverage costs, such as oceans, deserts, and remote mountainous areas, satellite communication can solve communication problems. Emergency communication: In extreme situations such as disasters like earthquakes that render cellular communication infrastructure unavailable, satellite communication can quickly establish communication connections. Providing industry applications: For example, for long-distance, latency-sensitive services, satellite communication can reduce transmission latency. It is foreseeable that in future wireless communication systems, satellite communication systems and terrestrial cellular communication systems will gradually achieve deep integration, truly realizing the Internet of Things.

[0186] In some embodiments, in satellite communication scenarios, the long signal transmission distance between the transmitter and receiver results in significant data transmission time. For transmissions involving uplink and downlink relationships, it is determined that the terminal needs to compensate for propagation delay based on the base station configuration. Propagation delay compensation can be applied in various operations, such as the transmission of Physical Uplink Shared Channel (PUSCH) scheduled by Downlink Control Information (DCI); the transmission of Hybrid Automatic Repeat reQuest (HARQ) feedback information; and the transmission of Media Access Control Element (MAC CE), etc. Please refer to [link to relevant documentation]. Figure 1b This refers to a scenario involving uplink and downlink timing alignment at the base station side; please refer to [link to relevant documentation]. Figure 1c This refers to a scenario where uplink and downlink timings are misaligned on the base station side.

[0187] In some embodiments, the terminal needs to acquire location information to determine the timing compensation information for uplink transmission. The terminal can determine its own location information through a GNSS measurement module. For IoT terminals, simultaneous operation of the cellular module and the GNSS module is not required; only sporadic transmission may be supported.

[0188] In some embodiments, after acquiring GNSS measurement results, the terminal can report the GNSS availability time to the base station via the GNSS validity period. In some embodiments, the terminal determines the GNSS availability time as the reported GNSS validity period, and the base station does not perform any additional configuration. However, the terminal's GNSS availability time may be subject to changes in the base station's operation. The terminal can ensure its uplink synchronization based on the base station's control, such as time-frequency synchronization control. In this case, if the terminal performs GNSS measurements after the GNSS validity period has expired, it will cause unnecessary power consumption.

[0442] In some embodiments, the first information is used to indicate time information related to a first time; the first time is the valid time of location information obtained based on the Global Navigation Satellite System (GNSS).

[0444] In some embodiments, the above methods may include the methods described in the embodiments of the instruction information system side, terminal side, network device side, etc., which will not be repeated here.

[0445] This disclosure relates to an information indication method, the method comprising:

[0446] In some embodiments, the terminal reports information related to GNSS validity duration, which includes at least one of the following: the start position of the current GNSS validity duration; the full duration of the current GNSS validity duration; the remaining available time of the current GNSS validity duration; and the end position of the current GNSS validity duration. Here, GNSS validity duration corresponds to the validity period in this disclosure.

[0447] In some embodiments, the terminal determines the GNSS validity duration based on the second information from the base station.

[0448] In some embodiments, the terminal receives second information from the base station, such as higher-layer signaling (RRC), MAC CE, or physical-layer signaling (DCI), to determine the GNSS validity duration.

[0449] In some embodiments, the second information is used for the available time period of GNSS information for the terminal determiner.

[0450] In some embodiments, the length of the GNSS validity duration indicated in the second information is greater than or equal to the length of the GNSS validity duration reported by the terminal.

[0451] In some embodiments, the second information may include: the start position and length information of the GNSS validity duration; and the start position and end position information of the GNSS validity duration.

[0452] In some embodiments, if the GNSS validity duration configured by the base station is determined to be greater than the GNSS validity duration most recently reported by the terminal, the terminal determines that it supports adjusting its uplink synchronization based on the time-frequency adjustment command of the base station.

[0453] In some embodiments, the terminal receives a time-frequency adjustment command sent by the base station to determine its uplink time-frequency synchronization information. The time-frequency adjustment command can be sent via higher-layer signaling such as RRC signaling or MAC CE, or via physical-layer signaling such as DCI.

[0454] In some embodiments, the terminal determines the starting position for detecting the time-frequency adjustment command by including:

[0455] Method 1: Start listening from the point where the GNSS validity duration expires;

[0456] In this manner, after the terminal determines that the available time end position of the GNSS validity duration configured by the base station is the end position determined in the reporting information, the terminal starts receiving target instructions from the end position of the GNSS validity duration determined in the reporting information. The target instructions carry indication information related to the time and frequency adjustment command.

[0457] Alternatively, in another implementation, the terminal may begin receiving target instructions after a predefined time, such as after a subframe X, following the end position of the GNSS validity duration determined from the reported information. These target instructions carry indication information related to time-frequency adjustment commands. X is either predefined or determined by receiving second information from the base station.

[0458] Method 2: Start listening after receiving the second GNSS validity duration information;

[0459] In this method, after receiving the second GNSS validity duration information, the terminal starts receiving the target instruction after a predefined or pre-configured time delay or without delay. The target instruction carries indication information related to the time and frequency adjustment command.

[0460] Method 3: Always listen

[0461] In this method, regardless of whether the GNSS validity duration configured by the base station is greater than the GNSS validity duration most recently reported by the terminal, the terminal always receives the target instruction, which carries indication information related to the time-frequency adjustment command.

[0462] In some embodiments, the terminal autonomously determines the GNSS validity duration.

[0463] When the terminal does not receive the second information indication of GNSS validity duration from the base station, the terminal determines that the GNSS validity duration is the GNSS validity duration most recently reported by the terminal. If the terminal determines that the GNSS validity duration has expired, it receives a time-domain or frequency-domain adjustment command from the base station within a predefined time window. The start position of this predefined time window is the time when the GNSS validity duration expired, and its length is configurable.

[0464] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

[0465] This disclosure also provides apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units for implementing the steps performed by the network device in any of the above methods.

[0466] It should be understood that the division of the units in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing computer instructions. The processor calls the computer instructions stored in the memory to implement any of the above methods or to implement the functions of the units in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units in the device can be implemented as hardware circuits. The functionality of some or all units can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between these logic gates are configured through a configuration file, thereby achieving the functionality of some or all of the units. All units of the above device can be implemented entirely through processor-invoked software, entirely through hardware circuits, or partially through processor-invoked software with the remaining parts implemented through hardware circuits.

[0467] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a type of microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), a Deep Learning Processing Unit (DPU), etc.
