[0042] GNSS measurement-related processes suffer from high power consumption.

[0043] This disclosure provides an information indication method, apparatus and system, communication device and storage medium.

[0044] In a first aspect, embodiments of this disclosure provide an information indication method, wherein the method is executed by a terminal, and the method includes:

[0045] Receive the first message;

[0046] The first information is used to indicate whether the terminal should extend or not extend the first time; the first time is the effective time of the location information obtained by the terminal based on the Global Navigation Satellite System (GNSS).

[0047] In the above embodiments, the terminal can receive first information indicating whether or not to extend the first time. After receiving the first information, the terminal can extend or not extend the first time based on the first information. When it is determined to extend the first time, the terminal can extend the first time based on the first information. In this way, the number of times the terminal obtains location information can be reduced, thereby reducing the terminal's power consumption and extending the terminal's battery life.

[0048] In conjunction with some embodiments of the first aspect, in some embodiments, the first information indicates a second time; the method further includes: in response to determining that the duration of the second time is greater than the duration of the first time, extending the first time.

[0049] In the above embodiments, the terminal may trigger the terminal to extend the first time when it is determined that the duration of the second time indicated by the first information is greater than the duration of the first time.

[0050] In conjunction with some embodiments of the first aspect, in some embodiments, extending the first time period includes: extending the first time period corresponding to the first time period to a second time period; wherein the second time period includes the first time period and the third time period.

[0051] In the above embodiments, since the second time period includes the first time period and the third time period, the terminal expands the time period range and extends the first time, making the effective time of the location information acquired by GNSS longer.

[0052] In conjunction with some embodiments of the first aspect, in some embodiments, the third time period is predefined or configured by the network device.

[0053] In the above embodiments, the configuration of the third time period is more flexible because it can be predefined or configured by network devices.

[0054] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: receiving second information; wherein the second information is used to indicate a third time period;

[0055] In the above embodiments, the network device can indicate the third time period through the second information, and the configuration of the third time period is more flexible.

[0056] In conjunction with some embodiments of the first aspect, the duration of the third time period indicated by the second information sent at different times is different.

[0057] In the above embodiments, since the duration of the third time period indicated by the second information sent at different times can be different, the network device can dynamically configure different third time periods through the second information, making the configuration of the third time period more flexible.

[0058] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: determining a third time period based on a first value in the second information and a mapping relationship between the first value and a time period.

[0059] In the above embodiments, since the mapping relationship includes the correspondence between the first value and the time period, after the terminal receives the second information, it can quickly determine the third time period based on the first value and the mapping relationship in the second information. This explicit indication method can reduce the signaling overhead of the second information.

[0060] In some embodiments, in conjunction with the first aspect, the method further includes: receiving a first signaling; and determining a third time period based on the detection period of the first signaling and the mapping relationship between the detection period and the time period.

[0061] In the above embodiments, since the mapping relationship includes the mapping relationship between the detection period and the time period, after the terminal receives the first signaling, it can quickly determine the third time period based on the detection period and mapping relationship of the first signaling. This implicit indication method can reduce signaling overhead.

[0062] In conjunction with some embodiments of the first aspect, in some embodiments, the first signaling carries second information, which is used to indicate a third time period.

[0063] In the above embodiments, since the first signaling carries the second information, the terminal can determine the third time period based on either the indication of the second information or the detection period of the first signaling. In this way, the indication of the third time period will be more diverse.

[0064] In conjunction with some embodiments of the first aspect, in some embodiments, the mapping relationship is predefined or configured by the network device.

[0065] In the above embodiments, the mapping relationship can be predefined or configured by the network device, making the configuration of the mapping relationship more flexible.

[0066] In conjunction with some embodiments of the first aspect, in some embodiments, receiving the second information includes: receiving the second information via at least one of the following signaling methods: DCI; MAC CE.

[0067] In the above embodiments, since the second information can be received through DCI or MAC CE, on the one hand, at least one of the existing DCI and MAC CE can be reused without setting new signaling, which can save resources; on the other hand, the method of receiving the second information will be more flexible.

[0068] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: determining the start time of the third time period.

[0069] In the above embodiments, after determining the start time of the third time period, the terminal can determine the time period corresponding to the extended first time period.

[0070] In conjunction with some embodiments of the first aspect, in some embodiments, determining the start time of the third time period includes: determining the start time based on the failure time of the first time period.

[0071] In the above embodiments, since the start time of the third time period can be determined based on the failure time, the location information acquired by GNSS can be kept valid in a timely manner after the failure of the first time period.

[0072] In conjunction with some embodiments of the first aspect, in some embodiments, determining the start time based on the failure time of the first time includes: determining the start time as the failure time; or, determining the start time as a time after a first time interval following the failure time.

[0073] In the above embodiments, the failure time of the first time period can be determined as the start time of the third time period. This can reduce the intermittent failure of the location information acquired by GNSS. The start time can also be the time after the failure time, after a first time interval. The first time interval can be set to different lengths as needed, thus making the location configuration of the start time more flexible.

[0074] In conjunction with some embodiments of the first aspect, in some embodiments, the first duration is predefined or configured by the network device.

[0075] In the above embodiments, the first time period can be predefined or configured by the network device, and the configuration of the first time period is more flexible.

[0076] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: receiving third information, the third information indicating the start time; determining the start time of the third time period includes: determining the start time of the third time period based on the third information.

[0077] In the above embodiments, the third information can directly indicate the start time, thus enabling dynamic configuration of the start time.

[0078] In some embodiments, in conjunction with the first aspect, the method further includes: receiving fourth information; and determining the start time of the third time period based on the effective time of the fourth information.

[0079] In the above embodiments, since the start time of the third time period can be determined based on the effective time of the fourth information, the location information acquired by GNSS can be kept valid in a timely manner after the fourth information takes effect.

[0080] In conjunction with some embodiments of the first aspect, in some embodiments, the start time of the third time period is determined based on the effective time of the fourth information, including: determining the start time as the time after the effective time interval of the second duration.

[0081] In the above embodiments, the start time can be the time after the failure time, after a second time interval. The first time interval can be set to different sizes according to requirements, so the configuration of the start time will be more flexible.

[0082] In conjunction with some embodiments of the first aspect, in some embodiments, the second duration is predefined or configured by the network device.

[0083] In the above embodiments, the second duration can be predefined or configured by the network device, making the configuration method more flexible.

[0084] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: receiving fifth information during a third time period; and determining the time to perform GNSS measurements based on the fifth information.

[0085] In the above embodiments, the terminal can determine the time to perform GNSS measurements based on the instructions of the fifth information.

[0086] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: sending a sixth message; wherein the sixth message is used to indicate: the ability to maintain the terminal in a Radio Resource Control (RRC) connection state in the event that a first-time failure is determined.

[0087] In the above embodiments, the peer can know that the terminal has the ability to maintain the terminal in the Radio Resource Control (RRC) connection state when it is determined that the terminal has failed in the first instance.

[0088] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: determining an immediate failure and maintaining the terminal in an RRC connection state.

[0089] In the above embodiments, if an immediate failure is determined, the terminal can remain in the RRC connected state without switching to the RRC disconnected state. This reduces the power consumption caused by having to switch back to the RRC connected state after switching to the RRC disconnected state for GNSS measurements, thus extending the terminal's battery life.

[0090] In conjunction with some embodiments of the first aspect, the method further includes: receiving seventh information; wherein the seventh information instructs the terminal to maintain the terminal in a Radio Resource Control (RRC) connection state in the event that a first-time failure is determined.

[0091] In the above embodiments, the peer can instruct the terminal to maintain the terminal in the Radio Resource Control (RRC) connection state in the event of a first-time failure through the seventh information, so that the terminal can continue to perform GNSS measurements.

The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0174] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0175] 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), or 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.

[0177] 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... Figure 1a All or part of the main body, or may include Figure 1a Other entities besides the main body, the number and form of each entity are arbitrary, the connection relationship between the entities is illustrative, the entities may not be connected or may be connected, and the connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0178] 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, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0179] 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.

[0180] 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.

[0181] 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.

[0182] 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.

[0183] 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.

[0184] Figure 2 This is an interactive schematic diagram illustrating an information indication method according to an embodiment of the present disclosure. For example... Figure 2 As shown, this disclosure relates to an information indication method for an information indication system 100, the method comprising:

[0185] Step S2101: The terminal sends the sixth information to the network device.

[0186] In some embodiments, the network device receives sixth information sent by the terminal.

[0187] In some embodiments, the sixth information is the sixth indication information.

[0188] In some embodiments, the sixth piece of information may be information indicating the capabilities of the terminal. For example, terminal capability information.

[0189] In some embodiments, the sixth information is used to indicate the ability to maintain the terminal in a Radio Resource Control (RRC) connection state in the event of a determined first-time failure.

[0190] In some embodiments, the first time is the valid time of the location information acquired by the terminal based on the Global Navigation Satellite System (GNSS). The first time can be the first valid time.

[0191] In some embodiments, the sixth information may be carried through the first information field.

[0192] For example, when the first information field indicates "1", the sixth information field indicates that the terminal has the ability to maintain the terminal in the RRC connection state in the event that the terminal is determined to fail in the first time.

[0193] In some embodiments, the terminal determines whether it has the capability to maintain an RRC connection in the event of an immediate failure. If it does, the terminal sends a sixth message to the network device.

[0194] In some embodiments, keeping the terminal in the RRC connected state may mean that the terminal does not switch to the RRC idle state or the RRC inactive state. The RRC idle state or the RRC inactive state may also be referred to as the RRC disconnected state.

[0195] In step S2102, the network device sends the seventh information to the terminal.

[0196] In some embodiments, the terminal receives the seventh information sent by the network device.

[0197] In some embodiments, the seventh information is a seventh indication information.

[0199] In some embodiments, the seventh information can be carried through the second information field. For example, when the second information field indicates "1", the seventh information indicates that the terminal maintains the terminal in the RRC connection state in the event of a first-time failure.

[0200] In some embodiments, the network device may send the seventh information to the terminal based on the sixth information after receiving the sixth information.

[0201] In some embodiments, after receiving the sixth information, the network device determines, based on the sixth information, that the terminal has the ability to maintain the terminal in the RRC connection state in the event of a first-time failure, and sends the seventh information to the terminal.

[0208] In some embodiments, the duration of the second time indicated by the first information is longer than the duration of the first time.

[0209] In some embodiments, the end time of the second time indicated by the first information is after the end time of the first time.

[0210] In some embodiments, the duration of the second time indicated by the first information is longer than the duration of the first time, or the end time of the second time is after the end time of the first time, and the first information is used to instruct the terminal to extend the first time.

[0211] In some embodiments, the network device may send first information to the terminal based on the sixth information after receiving the sixth information.

[0212] In some embodiments, after receiving the sixth information, the network device determines, based on the sixth information, that the terminal has the ability to maintain the terminal in the RRC connection state in the event of a first-time failure, and sends the first information to the terminal.

[0213] Step S2104, terminal expansion is implemented immediately.

[0214] In some embodiments, the terminal determines that the duration of the second time indicated by the first information is greater than the duration of the first time, and the terminal extends the first time.

[0215] In some embodiments, if the second time indicated by the first information obtained from the terminal is greater than the first time, the terminal extends the first time period corresponding to the first time period to the second time period; wherein, the second time period includes the first time period and the third time period.

[0216] In one embodiment, after the terminal determines that the end time of the second time indicated by the first information is after the end time of the first time, the terminal extends the first time.

[0217] In some embodiments, if the end time of the second time indicated by the first information obtained from the terminal is after the end time of the first time, the first time period corresponding to the first time is extended to the second time period; wherein, the second time period includes the first time period and the third time period.

The physical layer signaling may be Downlink Control Information (DCI) signaling. The higher layer signaling may be MAC CE signaling or RRC signaling.

[0226] In some embodiments, the terminal determines the third time period based on the first value of the second information and the mapping relationship between the first value and the time period.

[0227] In some embodiments, the first value may be an indicator value.

[0228] In one embodiment, the mapping relationship is predefined or configured by the network device.

[0229] In some embodiments, the terminal determines a third time period based on a first value in the second information and a mapping relationship between the first value and a time period, wherein the mapping relationship and the second information may be obtained from a network device.

[0233]

[0234] Of course, the above mapping relationship can also be stored in the terminal in advance in a predefined way, or be directly specified by the communication protocol or pre-configured by the user, and there is no limitation here.

[0235] In some embodiments, the terminal determines a third time period based on a first value in the second information and a mapping relationship between the first value and a time period, wherein the mapping relationship may be predefined and the second information may be received from a network device.

Exemplarily, the first signaling may be a target signaling. The target signaling may be a signaling determined from multiple signaling signals, for example, a signaling carrying a command for time-frequency domain adjustment.

[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 indication information indicating the ability to maintain connectivity even after the GNSS validity duration has expired. The GNSS validity duration corresponds to the first validity period in this disclosure.

[0447] In some embodiments, if a terminal determines that it can be in a maintained connection (RRC connected) state when the original GNSS validity duration has expired, the determination method may include:

[0448] In some embodiments, the terminal receives an indication from the base station to determine that, even if the original GNSS validity period has expired, it can remain in the connected state without entering the IDLE state.

[0449] In some embodiments, the terminal receives GNSS validity duration configuration information sent by the base station. If it is determined that the GNSS validity duration indicated in the configuration information is greater than the GNSS validity duration reported by the terminal, then it is determined that the GNSS validity duration can be extended.

[0450] In some embodiments, the terminal determines the extended time of the GNSS validity duration, which can be achieved in the following ways:

[0451] In some embodiments, the fixed time is extended.

[0452] In this method, after the original GNSS validity duration of the terminal expires, it can be extended for a fixed period of time. This fixed period can be determined by the configuration information of the receiving base station or by a predefined method.

[0453] In some embodiments, extended variable time

[0454] In this method, after the original GNSS validity duration of the terminal expires, it can be extended for a period of time, the length of which can be dynamically indicated. The terminal can receive configuration information from the base station or determine the configuration information of the time period set through a predefined method. The terminal determines the specific time period that can be extended after the original GNSS validity duration expires, based on either explicit or implicit methods.

[0455] In one implementation, the terminal determines the specific extended time period information to be used through physical layer signaling or MAC CE sent by the base station.

[0456] In another implementation, the correspondence between target signaling and time period information can be predefined or preconfigured. The terminal determines the time period information to use based on the detected target signaling and the correspondence. For example, the target signaling can be signaling used to instruct the terminal on time-frequency domain adjustment commands, and the correspondence between the detection configuration of the time-frequency adjustment commands and the time period information can be predefined or preconfigured. For example, if the predefined signaling detection period is 5ms, it represents time period 1; if the predefined signaling detection period is 10ms, it represents time period 2. The terminal determines the extended time period information to use by detecting the target command and the correspondence.

[0457] In some embodiments, the terminal determines the starting position of the extended time of the GNSS validity duration, which can be achieved in the following ways:

[0458] In some embodiments, the determination is based on the GNSS validity duration expires.

[0459] In this method, the terminal determines the extension time based on the GNSS validity duration expiration time. The start position of the extension time can be either the GNSS validity duration expiration time or X subframes after the GNSS validity duration expiration time. X is predefined or pre-configured.

[0460] In some embodiments, the indication time is determined based on the extended signaling.

[0461] In this method, the terminal determines the extended time based on information carried in the target signaling. The target instruction may be signaling carrying information indicating the extended time period.

[0462] In some embodiments, the timeframe is within a predefined or configurable period following the effective time of the extended signaling.

[0463] In this method, the terminal determines the start position of the extended time based on a predefined or configurable time period after the target signaling takes effect. For example, the target signaling may be signaling carrying the extended time period indication information. In one implementation, the terminal uses the effective time of the target signaling as the starting position after an interval of X subframes. X is predefined or preconfigured.

[0464] In some embodiments, the terminal is in an RRC connected state during the extended time period. Communication with the base station can be maintained normally during this extended time period. Furthermore, the terminal can also receive trigger commands from the base station during the extended time period to determine the time for performing GNSS measurements.

[0465] 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.

[0466] 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.

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.

[0468] 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.
