Description

Information processing method, communication device and storage medium related to uplink transmission Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to an information processing method, communication device, and storage medium related to uplink transmission. Background Art

[0002] Within a cell, there are multiple terminals located at varying distances from the base station. For example, the transmission lengths of the wireless links between a terminal at the cell edge and a terminal at the cell center differ. Therefore, by setting a timing advance (TA) for each terminal, uplink synchronization between terminals at different locations and the base station can be achieved.

[0003] Non-terrestrial networks (NTNs) can also be referred to as non-terrestrial networks. NTN base stations or their wireless components may be carried on satellites or drones. As a result, NTN communication wireless paths are generally longer than those used in TNs. Furthermore, in some cases, satellites or drones are moving relative to the ground, so the relative position between the terminal and the base station's wireless component can change dynamically. To maintain uplink synchronization, the terminal needs to accurately know its own location information to facilitate uplink synchronization compensation.

[0026] Embodiments of the present disclosure provide an information processing method, a communication device, a communication system, and a storage medium related to uplink transmission.

[0027] A first aspect provides an information processing method related to uplink transmission, which is executed by a terminal. The method includes: when satellite positioning information of the terminal meets a first condition, determining that the terminal can perform uplink transmission; and sending uplink transmission.

[0028] Based on the above scheme, under normal circumstances, when the satellite positioning information meets the first condition, the terminal will suspend uplink transmission or re-acquire high-precision satellite positioning information before uplink transmission. Since it is determined that the terminal can still perform uplink transmission, the delay of uplink transmission can be reduced.

[0029] In some embodiments of the first aspect,

[0030] When the satellite positioning information of the terminal meets the first condition and the terminal is in an idle state or an inactive state, it is determined that the terminal can perform the first uplink transmission.

[0032] Based on the above scheme, when the satellite positioning information meets the first condition, whether the uplink transmission can be performed is determined according to the Radio Resource Control (RRC) status of the terminal, rather than for all uplink transmissions, thereby reducing the confusion of the wireless environment caused by performing all uplink transmissions when the satellite positioning information of the terminal meets the first condition, and the low bit error rate of the uplink transmission received by the network device.

[0033] In some embodiments of the first aspect, the first uplink transmission includes at least one of the following: the first uplink transmission when the terminal does not maintain the timing advance adjustment value, the first uplink transmission after the terminal has a maintenance timing advance adjustment value and the terminal's time alignment timer TAT is not running or has timed out, a random access request, and a small data transmission SDT.

[0034] The above solution illustrates the first uplink transmission by way of example, and the specific implementation is not limited to the above example.

[0035] In some embodiments of the first aspect, the second uplink transmission includes at least one of the following: a random access request and a small data transmission SDT.

[0099] FIG1A is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0100] As shown in Figure 1A, a communication system 100 includes a terminal 101 and a network device 102. The network device 102 may include an access network device and / or a core network device.

[0101] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0105] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0106] In some embodiments, the core network device may be a single device including a first network element, or may be a plurality of devices or a group of devices, each including a first network element. The network element 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).

[0107] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0108] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0109] The embodiments of the present disclosure 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), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (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 utilizing other information processing methods related to uplink transmission, and next-generation systems based on these. Furthermore, multiple systems may be combined (for example, a combination of LTE and NR).

[0110] FIG1B shows an NTN communication system, which may include:

[0111] An aerial base station or a platform carrying the wireless portion of a base station; the platform may be a satellite and / or an unmanned aerial vehicle (UVA);

[0112] Gateway;

[0113] There is a service link (SL) between the terminal and the base station in the air.

[0114] There is a Feeder Link (FL) between the base station in the air and the ground gateway.

[0115] The gateway will be connected to the Data Network (DN).

[0116] Beam communication can be used between the base station and the terminal in the air. In this way, the beam is projected onto the ground to form a beam foot print.

[0117] Depending on how the satellite processes signals, it can be divided into transparent transmission mode and regeneration mode. In transparent transmission mode, as shown in Figure 1C, the NTN ground station transmits the gNB signal to the satellite. The satellite converts the signal to the satellite frequency band and then transmits it to the UE. Besides frequency conversion and signal amplification, the satellite does not demodulate the gNB signal, acting like a repeater.

[0118] The regeneration mode is shown in Figure 1D. After the NTN ground station sends the gNB signal to the satellite, the satellite first demodulates and decodes the signal, then re-encodes and modulates it (this process is called regeneration) and sends the regenerated signal through the satellite frequency band.

[0119] The following are descriptions of several NTNs:

[0120] NTN cells may include: terrestrial fixed cells and terrestrial mobile cells.

[0121] The coverage area of ​​a ground-fixed cell does not change over time.

[0122] The area of ​​an earth-moving cell on the ground changes over time.

[0123] In some cases, for a terrestrial fixed cell, service time information is broadcast in a system message, so that the terminal can determine the time when the terrestrial fixed cell provides service and / or stops providing service based on the service time information.

[0124] For NTN communications, the terminal needs to obtain satellite positioning information, perform uplink synchronization compensation based on the satellite positioning information, and then perform uplink transmission based on the compensated uplink synchronization. If the terminal's satellite positioning information fails or is not accurate enough, it is usually necessary to re-acquire the satellite positioning information before uplink transmission. However, it may be difficult for the terminal to obtain satellite positioning information with sufficient accuracy. In this case, the terminal's uplink transmission may not be possible or the uplink transmission delay may be large.

[0125] In view of this, an embodiment of the present disclosure provides an information processing method related to uplink transmission, which can be performed by the communication system shown in Figures 1A to 1D. As shown in Figure 2, the method may include:

[0126] S2101: The network device sends a network message to the terminal.

[0127] In some embodiments, the network device broadcasts, multicasts, or unicasts the network message to the terminals.

[0128] In some embodiments, the network message may include the first information and / or the second information.

[0129] In some embodiments, the first information and the second information may be sent to the terminal via different network messages.

[0130] In some embodiments, the first information and the second information may be sent to the terminal via the same network message.

[0131] In some embodiments, the first information is used to indicate a threshold associated with the second condition.

[0132] In some embodiments, the second information is used to indicate a threshold associated with the third condition.

[0133] In some embodiments, the network message may further include third information.

[0134] The third information may be used to indicate information related to the first condition.

[0135] In some embodiments, the network device broadcasts a system information block carrying configuration information.

[0136] In some embodiments, the system information block (SIB) 1 and / or SIB19, etc.

[0137] In some embodiments, SIB19 may also carry ephemeris information of NTN satellites.

[0138] In some embodiments, the network message carrying the first information and / or the second information may further include: an RRC message and / or a Media Access Control (MAC) message or downlink control information (DCI).

[0139] It is worth noting that: in some embodiments, S2101 is an optional step. For example, the condition information such as the thresholds related to the first condition, the second condition and the third condition can be agreed upon by the protocol. In this case, the network device does not need to send the network message to the terminal.

[0140] In some embodiments, the first information and / or the second information may be carried in an RRC release message and sent to a terminal in a connected state. In this case, the terminal in the connected state enters an idle state or an inactive state after receiving the RRC release message. In this way, when in the inactive state or idle state, the terminal can determine whether to continue uplink transmission when the satellite positioning information meets the first condition based on the network message.

[0141] In some embodiments, the first information and / or the second information may be carried in an RRC reconfiguration message and sent to a terminal in an idle state and / or an inactive state. In this case, the terminal in the idle state and the inactive state enters a connected state after receiving the RRC reconfiguration message. In this way, the terminal in the connected state can determine whether to continue uplink transmission when the satellite positioning information meets the first condition based on the network message.

[0142] S2102: When the satellite positioning information of the terminal meets the first condition, the terminal determines that uplink transmission can be performed.

[0143] In some embodiments, the satellite positioning information may include but is not limited to at least one of the following:

[0144] Global Navigation Satellite System (GNSS) position information, which may be position information obtained based on GNSS positioning;

[0145] Beidou Navigation Satellite System (BDS) location information may be location information obtained based on BDS positioning.

[0146] Of course, the above is merely an example of satellite positioning information. In a specific implementation, the satellite positioning information may be location information obtained based on satellite system positioning and / or location information obtained based on NTN.

[0147] In some embodiments, the satellite positioning information of the terminal satisfies the first condition if: the last satellite positioning information acquired by the terminal satisfies the first condition, or any satellite positioning information acquired by the terminal satisfies the first condition.

[0148] In some embodiments, the satellite positioning information meeting the first condition may include but is not limited to at least one of the following:

[0149] Satellite positioning information fails;

[0150] The accuracy of the satellite positioning information is lower than the specified accuracy threshold;

[0151] The satellite positioning information of the terminal is valid and the accuracy of the satellite positioning information does not meet the third condition.

[0152] In some embodiments, satellite positioning information failure may include but is not limited to at least one of the following:

[0153] The validity period of satellite positioning information has expired;

[0154] The accuracy of the satellite positioning information is lower than the minimum accuracy threshold for valid satellite positioning information.

[0155] In some embodiments, the satellite positioning information of the terminal is valid and the accuracy of the satellite positioning information does not meet the third condition, which may include: the satellite positioning information is valid and the accuracy of the satellite positioning information is less than a second accuracy threshold.

[0156] In some embodiments, the second accuracy threshold may be higher than a minimum accuracy threshold for valid positioning information.

[0157] In some embodiments, the second accuracy threshold may be higher than a minimum accuracy threshold for valid positioning information and lower than a minimum accuracy threshold for high-precision satellite positioning information.

[0158] In some embodiments, the second accuracy threshold may be lower than a minimum accuracy threshold for high-precision satellite positioning information.

[0159] In the embodiment of the present disclosure, the uplink transmission may include uplink transmission of any service data.

[0160] Exemplarily, the uplink transmission may include but is not limited to at least one of the following:

[0161] Arbitrary configuration of transmission on the physical uplink shared channel and / or random access channel;

[0162] Uplink transmission with a transmission delay tolerance value less than the specified value;

[0163] Uplink transmission with data volume less than the data volume threshold;

[0164] Uplink transmissions where the transmission resources occupied are less than the resource threshold;

[0165] Uplink transmission of designated resources occupied;

[0166] In some embodiments, the uplink transmission may be uplink transmission having any two or more of the above characteristics.

[0167] In some embodiments, when the satellite positioning information of the terminal meets the first condition, determining that the terminal can perform uplink transmission includes: when the satellite positioning information of the terminal meets the first condition and the terminal is in an idle state or an inactive state, determining that the terminal can perform the first uplink transmission.

[0168] In some embodiments, the first uplink transmission may also be referred to as an initial uplink transmission.

[0169] In some embodiments, when the satellite positioning information of the terminal meets the first condition, determining that the terminal can perform uplink transmission includes: when the satellite positioning information of the terminal meets the first condition and the terminal is in a connected state, determining that the terminal can perform a second uplink transmission.

[0170] In some embodiments, when the satellite positioning information of the terminal meets the first condition, determining that the terminal is capable of performing uplink transmission includes: when the satellite positioning information of the terminal meets the first condition and the terminal is in an idle state or an inactive state, determining that the terminal is capable of performing a first uplink transmission; and when the satellite positioning information of the terminal meets the first condition and the terminal is in a connected state, determining that the terminal is capable of performing a second uplink transmission.

[0171] When the terminal is in an idle state or an inactive state, there is no wireless connection established between the terminal and the base station. If the satellite positioning information of the terminal meets the first condition, the initial uplink transmission can be sent.

[0172] The initial uplink transmission here can be understood as the first uplink transmission or the first transmission when the terminal accesses the network again.

[0173] In some embodiments, the initial uplink transmission includes at least one of the following:

[0174] The first uplink transmission when the terminal does not maintain the timing advance adjustment value;

[0175] The first uplink transmission after the terminal has maintained the timing advance adjustment value and the terminal's time alignment timer (TAT) is not running or has timed out;

[0176] Random access request;

[0177] Small data transmission SDT

[0178] In some embodiments, the timing advance adjustment value may be a TA adjustment value sent by a timing advance control (TA Command, TAC) of the network device.

[0179] The TAT may be a time alignment timer that may be started after receiving the TAC.

[0180] TAT not started means TAT ​​is not started.

[0181] If TAT runs overtime, it means that TAT has been started and run at least once and then timed out.

[0182] The random access request may include a four-step random access random access request and / or a two-step random access request.

[0183] The random access request for the four-step random access may include a message (Msg) 1. The random access request for the two-step random access may include a message A.

[0184] In some embodiments, small data transmission (SDT) may include: configured grant (CG) SDT and / or random access (RA) SDT.

[0185] CG-SDT is an SDT sent on CG resources. The CG resources may be resources configured on the Physical Uplink Shared Channel (PUSCH), but are not limited to resources configured on the PUSCH.

[0186] The RA-SDT may be an SDT sent using a random access procedure, for example, an SDT sent using Msg1 and / or MsgA.

[0187] In some embodiments, the second uplink transmission may include but is not limited to a random access request and / or a small data transmission.

[0188] In some embodiments, the SDT for a terminal in a connected state may also include a CG-SDT and / or a RA-SDT. The random access request for a terminal in a connected state may also include: Msg1 and / or MsgA.

[0189] In some embodiments, when the satellite positioning information of the terminal meets a first condition and the current state of the terminal meets a second condition, it is determined that the terminal is capable of performing uplink transmission.

[0190] That is, when the terminal meets the first condition and the second condition, the terminal is allowed to continue uplink transmission.

[0191] In some embodiments, the current state of the terminal satisfies the second condition, including at least one of the following:

[0192] The distance between the current estimated position of the terminal and the last invalid satellite positioning information is less than a first distance threshold;

[0193] The time interval between the current time and the expiration time of the last expired satellite positioning information is less than the first time threshold;

[0194] The accuracy of the satellite positioning information of the terminal is greater than a first accuracy threshold;

[0195] The terminal's TAT ​​has timed out, is not running, or has stopped.

[0196] In some embodiments, the first distance thresholds associated with different uplink transmissions are different, for example, the first distance threshold corresponding to a random access request and the first distance threshold corresponding to an SDT.

[0197] In some embodiments, different frequency ranges used by a terminal may be associated with different first distance thresholds. For example, the frequency ranges used by the terminal may include FR1, FR2, and / or FR3. For example, the average frequency of FR2 may be higher than the average frequency of FR1. The average frequency of FR3 may be lower than the frequency range of FR2 and higher than the frequency range of FR1.

[0198] In some embodiments, the magnitude of the average frequency of FR is negatively correlated with the magnitude of the first distance threshold.

[0199] In some embodiments, different terminal movement speeds are associated with different first distance thresholds. It is worth noting that the movement speed can be the absolute movement speed of the terminal relative to the ground, or the relative movement speed relative to the carrying platform.

[0200] In some embodiments, the moving speed is negatively correlated with the first distance threshold.

[0201] In some embodiments, in some embodiments, the current state of the terminal satisfies the second condition including:

[0202] The terminal is expected to be unable to regain valid satellite positioning information or satellite positioning information with an accuracy higher than the second accuracy threshold within the specified time. In this case, if you continue to wait for regaining valid or high-precision satellite positioning information before sending the uplink transmission, it will cause a serious timeout of the uplink transmission. If it is expected that valid satellite positioning information or satellite positioning information with an accuracy higher than the second accuracy threshold can be regained within the specified time, you can wait to regain valid satellite positioning information or satellite positioning information with an accuracy higher than the second accuracy threshold, and perform uplink transmission based on the regained satellite positioning information to ensure the high reliability of the uplink transmission. Of course, this is just an example, and the specific implementation is not limited to the above example.

[0203] The second condition corresponding to the terminal being unable to regain valid satellite positioning information or satellite positioning information with an accuracy higher than a second accuracy threshold within a specified time may be implemented in combination with any one of the aforementioned second condition examples.

[0204] In some embodiments, the first time thresholds associated with different uplink transmissions are different. For example, the first time thresholds associated with random access requests and / or SDTs are different.

[0205] In some embodiments, different frequency ranges used by the terminal are associated with different first time thresholds.

[0206] In some embodiments, the first time thresholds associated with different moving speeds of the terminal are different.

[0207] In some embodiments, the first accuracy thresholds associated with different uplink transmissions are different.

[0208] In some embodiments, different frequency ranges used by the terminal are associated with different first accuracy thresholds.

[0209] In some embodiments, different first accuracy thresholds are associated with different moving speeds of the terminal.

[0210] In some embodiments, when the satellite positioning information of the terminal is invalid and the distance between the current estimated position of the terminal and the last invalid satellite positioning information is less than a first distance threshold, it is determined that the terminal is capable of performing uplink transmission.

[0211] In some embodiments, when the satellite positioning information of the terminal is invalid and the time interval between the current moment and the invalidation moment of the last invalid satellite positioning information is less than a first time threshold, it is determined that the terminal is capable of performing uplink transmission.

[0212] In some embodiments, when the satellite positioning information of the terminal is valid and the accuracy of the satellite positioning information does not meet the second condition, and the accuracy of the satellite positioning information is greater than a first accuracy threshold, it is determined that the terminal is capable of performing uplink transmission.

[0213] In some embodiments, when the satellite positioning information of the terminal is valid and the accuracy of the satellite positioning information does not meet the second condition, and the distance between the current estimated position of the terminal and the last invalid satellite positioning information is less than the second distance threshold, it is determined that the terminal can perform uplink transmission.

[0214] In some embodiments, when the satellite positioning information of the terminal is valid and the accuracy of the satellite positioning information does not meet the second condition, and the time interval between the current moment and the expiration moment of the last invalid satellite positioning information is less than the second time threshold, it is determined that the terminal is capable of performing uplink transmission.

[0215] S2103: The terminal sends an uplink transmission to the network device.

[0216] For example, when the satellite positioning information meets the first condition, the terminal sends an executable uplink transmission to the network device.

[0217] In some embodiments, when the satellite positioning information meets the first condition, the terminal in the idle state and / or the inactive state sends a first uplink transmission to the network device.

[0218] In some embodiments, when the satellite positioning information meets the first condition, the terminal in the connected state sends a second uplink transmission to the network device.

[0219] In some embodiments, when a terminal in an idle state and / or an inactive state has a first uplink transmission, the terminal sends the first uplink transmission to the network device.

[0220] In some embodiments, when a terminal in an idle state and / or an inactive state has a second uplink transmission, the terminal sends the second uplink transmission to the network device.

[0221] As shown in FIG3 , an embodiment of the present disclosure provides a method for processing information related to uplink transmission, wherein the method is performed by a terminal and includes:

[0222] S3101: Receive network messages.

[0223] In some embodiments, the network message may include the first information and / or the second information.

[0224] In some embodiments, for the related description of the first information and / or the second information, please refer to the related description of the embodiment corresponding to FIG2 .

[0225] S3102: When the satellite positioning information of the terminal meets the first condition, determine that the terminal is capable of performing uplink transmission.

[0226] In some embodiments, when the satellite positioning information of the terminal meets a first condition and the terminal is in an idle state or an inactive state, it is determined that the terminal is capable of performing the first uplink transmission.

[0227] In some embodiments, when the satellite positioning information of the terminal meets the first condition and the terminal is in a connected state, it is determined that the terminal is capable of performing the second uplink transmission.

[0228] In some embodiments, the first uplink transmission includes at least one of the following: the first uplink transmission when the terminal does not maintain the time advance adjustment value; the first uplink transmission after the terminal has a maintenance time advance adjustment value and the terminal's time alignment timer TAT is not running or has timed out; a random access request; a small data transmission SDT.

[0229] In some embodiments, the second uplink transmission includes at least one of the following:

[0230] Random access request; small data transmission SDT.

[0231] In some embodiments, when the satellite positioning information of the terminal meets a first condition and the current state of the terminal meets a second condition, it is determined that the terminal is capable of performing uplink transmission.

[0233] The distance between the current estimated position of the terminal and the last invalid satellite positioning information is less than a first distance threshold;

[0234] The time interval between the current time and the expiration time of the last expired satellite positioning information is less than the first time threshold;

[0235] The accuracy of the satellite positioning information of the terminal is greater than a first accuracy threshold;

[0236] The terminal's TAT ​​has timed out, is not running, or has stopped.

[0237] In short, for the optional implementation of S3102, please refer to any optional implementation of the corresponding embodiment of Figure 2.

[0238] S3103: Send uplink transmission.

[0239] In some embodiments, uplink transmission may also be referred to as uplink transmission, and may also be abbreviated as UL transmission.

[0240] In some embodiments, the terminal in an idle state or an inactive state has a first uplink transmission, and sends the first uplink transmission to the network device when the satellite positioning information meets the first condition.

[0241] In some embodiments, the terminal in an idle state or an inactive state has a second uplink transmission, and sends the second uplink transmission to the network device when the satellite positioning information meets the first condition.

[0242] It is worth noting that: S3101 and / or S3103 are optional steps. For example, the first information and the second information can be determined according to the protocol, and there is no need to receive a network message from the network device. In some embodiments, when the satellite positioning information meets the first condition, whether to send an uplink transmission is determined based on the corresponding uplink transmission.

[0243] As shown in FIG4 , an embodiment of the present disclosure provides a method for processing information related to uplink transmission, wherein the method is performed by a network device and includes:

[0244] S4101: Send network message.

[0245] In some embodiments, the network message may include the first information and / or the second information.

[0246] The optional step of S4101 here can refer to S2101 of the corresponding embodiment in Figure 2.

[0247] In some embodiments, the first information is used to indicate a threshold associated with the second condition.

[0248] In some embodiments, the second information is used to indicate a threshold associated with the third condition.

[0249] In some embodiments, the network message may further include third information.

[0250] The third information may be used to indicate information related to the first condition.

[0251] In some embodiments, the network device broadcasts a system information block carrying configuration information.

[0252] In some embodiments, the system information block (SIB) 1 and / or SIB19, etc.

[0253] In some embodiments, SIB19 may also carry ephemeris information of NTN satellites.

[0254] In some embodiments, the network message carrying the first information and / or the second information may further include: an RRC message and / or a Media Access Control (MAC) message or downlink control information (DCI).

[0255] It is worth noting that: in some embodiments, S4101 is an optional step. For example, the condition information such as the thresholds related to the first condition, the second condition and the third condition can be agreed upon by the protocol. In this case, the network device does not need to send the network message to the terminal.

[0256] S4102: Receive uplink transmission.

[0257] In some embodiments, the network device receives an uplink transmission sent by the terminal.

[0258] For example, the network device receives uplink transmission sent by the terminal when the first condition and the second condition are met.

[0259] In some embodiments, the network device receives a first uplink transmission sent by a terminal in an idle state or an inactive state.

[0260] In some embodiments, the network device receives a second uplink transmission sent by a connected terminal.

[0261] The first uplink transmission and / or the second uplink transmission here may refer to any of the aforementioned embodiments.

[0262] It is worth noting that the above S4101 may be an optional step. For example, the condition information of the first condition, the second condition and / or the third condition may be agreed upon by the protocol, so the network device does not need to send a network message to the terminal.

[0263] The initial transmission time error for the terminal is Te_NTN=Te+Te_GNSS+Te_SAT.

[0264] Te may be a legacy timing error; Te_GNSS may be the accuracy of GNSS position information; and Te_SAT may be a position trajectory error of a serving satellite.

[0265] If the GNSS accuracy is less than 50m, the above formula is not applicable to determine Te_NTN. This is for application scenarios where the accuracy of GNSS position information in frequency range (FR) 1 exceeds 50m.

[0266] If the number of satellites is insufficient, a satellite is unavailable, or the satellite signal is weak, it is difficult to ensure that the accuracy of the GNSS position information obtained by the terminal does not exceed 50m.

[0267] If GNSS accuracy exceeds 50m, or the terminal is temporarily unable to acquire GNSS, it may still be able to perform uplink (UL) transmission. This is because the terminal's TA pre-compensation absorbs the round-trip time (RTT). Therefore, the cyclic prefix (CP) only needs to absorb UL desynchronization caused by other factors. The cyclic prefix is ​​a specific waveform with a specified duration for each symbol. This symbol may include, but is not limited to, Orthogonal Frequency Division Multiplexing (OFDM) symbols.

[0268] As shown in the table below, UL transmission can still function normally within a certain range of GNSS error. Furthermore, the GNSS tolerances for pre-transmission and push transmission are different.

[0269] The embodiments of the present disclosure provide an uplink transmission method, which allows the terminal to execute Msg1 or MsgA or CG-SDT, PUSCH or PUSCH if the GNSS position information of the UE cannot be located for a short time or the positioning accuracy is insufficient.

[0270] For a terminal in idle, inactive or connected state, if the terminal does not have valid GNSS location information or the accuracy of the GNSS location information does not meet certain requirements, the terminal can still send uplink transmissions to the NTN cell when certain conditions are met.

[0271] For example, for an idle or inactive terminal, if the terminal does not have valid GNSS location information or the accuracy of the GNSS location information does not meet certain requirements, the terminal can still send an initial uplink transmission to the NTN cell when certain conditions are met.

[0272] Example 1: The initial uplink information includes Msg1, MsgA, CG-SDT or initial uplink transmission of PUSCH transmission in the random access procedure.

[0273] Example 2: The initial uplink information can be N which is not maintained by the terminal. TA The first uplink transmission at the time.

[0274] Example 3: The initial uplink information can be N maintained by the terminal. TA However, the first uplink transmission after the TAT timer is not running or is stopped or times out.

[0275] Furthermore, the terminal can still send Msg1 / MsgA of the random access procedure to the NTN cell, but at least one of the following conditions needs to be met:

[0276] The terminal does not have valid GNSS location information, and the distance between the terminal's current estimated location and the most recent valid GNSS location is less than the threshold;

[0277] The terminal does not have valid GNSS location information, and the time from the current moment to the moment when the terminal GNSS location information becomes invalid is less than the threshold;

[0278] The terminal has low-precision GNSS location information, and the accuracy of the GNSS location information is greater than the accuracy threshold corresponding to the valid GNSS location information;

[0279] The terminal has relatively low-precision GNSS location information, and the distance between the terminal's current estimated location and the nearest valid GNSS location that meets the accuracy requirement is less than a threshold.

[0280] If the GNSS location information is invalid, it means that the GNSS location information is unavailable. The terminal supports mobile position estimation based on sensors such as inertial sensors when the GNSS location information is unavailable, thereby determining the distance between the terminal's current position and the position indicated by the invalid GNSS location information or the low-precision GNSS location information.

[0281] In some embodiments, the distance threshold is configured via a system broadcast message or dedicated signaling, or is agreed upon by the system.

[0282] For example, the system broadcast message is SIB1 or SIB19. The dedicated signaling is RRC Release message or RRC reconfiguration message.

[0283] In some embodiments, the distance threshold may be configured separately for differentiating Msg1, MsgA, CG-SDT, RA-SDT, and PUSCH transmissions.

[0284] In some embodiments, the distance threshold can be configured separately for FR1, FR2, and FR3 frequency bands.

[0285] In some embodiments, the time threshold is configured via a system broadcast message or dedicated signaling, or is agreed upon by the system.

[0286] In some embodiments, the system broadcast message is such as SIB1 or SIB19. The dedicated signaling is such as RRC Release message and RRC Reconfiguration message.

[0287] In some embodiments, the time threshold may distinguish Msg1, MsgA, CG-SDT PUSCH, and PUSCH separate configuration.

[0288] In some embodiments, the time threshold may be configured separately for differentiating between the FR1 and FR2 frequency bands.

[0289] In some embodiments, the time threshold can be configured separately for different terminal movement speeds.

[0290] Example: For example, the terminal's mobile speed can be divided into N intervals, and a time threshold can be configured for each interval. For example, a threshold can be configured for only one speed interval, and the thresholds for other speed intervals can be scaled based on the speed interval. For example, if the time threshold configured for the speed interval [1, 10] is 100 seconds, then the time threshold for the speed interval [10, 100] is 10 seconds, and so on.

[0291] In some embodiments, the accuracy threshold is configured via a system broadcast message or dedicated signaling, or is agreed upon by the system.

[0292] Example: System broadcast message such as SIB1 or SIB19. Dedicated signaling such as RRC Release message and RRC Reconfiguration message.

[0293] In some embodiments, the location accuracy threshold may be configured to distinguish Msg1, MsgA, CG-SDT PUSCH, and PUSCH separately.

[0294] In some embodiments, the location accuracy threshold can be configured separately for FR1, FR2, and FR3 frequency bands.

[0295] In some embodiments, the GNSS position information accuracy not meeting certain requirements includes the position information accuracy being less than a system preset value or a system configured value.

[0296] System default values ​​do not require network devices to send network messages. System configuration values ​​may require network devices to configure via network messages.

[0297] Example: For the system default value, the GNSS position information accuracy of FR1 is 50 meters.

[0298] Example: For system preset values, the accuracy of GNSS position information in FR2 and / or FR3 is 15 meters.

[0299] Example: If a system configuration value is used, it can be configured through a system broadcast message or dedicated signaling.

[0300] In some embodiments, the method is applicable to the case where the TAT (time Alignment Timer) timer of the terminal times out or is not running.

[0301] In the embodiments of the present disclosure, 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 of other embodiments.

[0302] In the embodiments of the present disclosure, 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 of other embodiments.

[0303] The embodiments of the present disclosure also provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device or a core network device) in any of the above methods.

[0304] It should be understood that the division of the various units or modules in the above devices is merely a division of logical functions. In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions.

All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

[0305] In the embodiments of the present disclosure, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction reading and execution capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP); in another implementation, the processor can implement certain functions through the logical relationship of the hardware circuit, and the logical relationship of the above-mentioned hardware circuit is fixed or reconfigurable, such as a hardware circuit implemented by a processor as 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 to implement the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. 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.

[0306] As shown in FIG5A , an embodiment of the present disclosure provides a terminal, wherein the terminal includes:

[0307] The processing module 5101 is configured to determine that the terminal can perform uplink transmission when the satellite positioning information of the terminal meets a first condition.
