Abstract
Description
Information processing method, device and storage medium related to uplink transmission Technical Field
[0001] The present disclosure relates to the field of communication technologies, and in particular to an information processing method, 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.

[0028] Embodiments of the present disclosure provide a method, device, and storage medium for processing information related to uplink transmission.
[0029] In a first aspect, an embodiment of the present disclosure provides an information processing method related to uplink transmission, which is executed by a terminal and includes: when the satellite positioning information of the terminal meets a first condition, uplink transmission is performed during the operation of the uplink transmission timer.
[0030] Based on the above scheme, on the one hand, the terminal can continue to perform uplink transmission based on the uplink transmission timer when the satellite positioning information meets the first condition, so that the terminal does not need to stop uplink transmission after the satellite positioning information meets the first condition or re-acquire valid or high-precision satellite positioning information before uplink transmission. This is beneficial for the terminal to be able to perform uplink transmission in time when it cannot re-acquire satellite positioning information that meets the first condition in time, thereby reducing the delay of uplink transmission.
[0031] On the other hand, the uplink transmission timer is used to limit the time range for the terminal to perform uplink transmission when the satellite positioning information meets the first condition, thereby controlling the uplink transmission of the terminal when the satellite positioning information meets the first condition, so that the network device can determine the time range for receiving the uplink transmission of the terminal when the satellite positioning information of the terminal meets the first condition, which is beneficial for the network device and the terminal to achieve the unification of the transmission time of the uplink transmission that continues to be performed when the satellite positioning information meets the first condition.
[0032] In combination with some embodiments of the first aspect, in some embodiments, a time alignment timer TAT of the terminal is in a running state.
[0033] Based on the above solution, when the satellite positioning information meets the first condition and the TAT is running, the terminal can continue uplink transmission based on the uplink transmission timer. This not only ensures uplink time synchronization performance by utilizing the running TAT, but also allows for timely uplink transmission even if the terminal cannot promptly reacquire satellite positioning information that meets the first condition, thereby reducing uplink transmission latency.
[0034] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes one of the following:
[0035] The uplink transmission timer is in operation, restarting the uplink transmission timer;
[0036] The uplink transmission timer stops running and is restarted.
[0037] Based on the above scheme, when the satellite positioning information meets the first condition and the uplink transmission timer is running or stopped, the terminal restarts the uplink transmission timer so as to perform uplink transmission during the running period of the uplink transmission timer and reduce the delay of uplink transmission.
[0038] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:
[0039] The uplink transmission timer is not running, and the uplink transmission timer is started.
[0040] Based on the above solution, when the satellite positioning information meets the first condition and the uplink transmission timer is not running, the terminal starts the uplink transmission timer, so as to perform uplink transmission during the running period of the uplink transmission timer and reduce the delay of uplink transmission.
[0041] In conjunction with some embodiments of the first aspect, in some embodiments, the timing duration of the uplink transmission timer includes one of the following:
[0042] A first duration configured by the network device;
[0043] The second duration is determined by predefined rules.
[0044] Based on the above solution, the timing duration of the uplink transmission timer can be configured by the network device, or can be configured by the terminal according to predefined rules, thereby improving the flexibility of the duration configuration of the uplink transmission timer.
[0045] In conjunction with some embodiments of the first aspect, in some embodiments, the predefined rule includes one of the following:
[0046] The TAT timing duration is a predetermined value, and the second duration is determined based on the first duration;
[0047] The timing duration of the TAT is not the predetermined value, and the second duration is determined according to the remaining duration of the TAT.
[0048] Based on the above scheme, when configuring the timing duration of the uplink transmission timer, the terminal configures different timing durations for the uplink transmission timer according to different timing duration values of the terminal's TAT. Since the timing duration of the TAT is related to the effective time of the timing advance adjustment amount of the uplink transmission, the terminal can continue to use the effective timing advance adjustment amount to perform uplink transmission during the operation period of the uplink transmission timer.
[0049] In combination with some embodiments of the first aspect, in some embodiments, the method further includes: receiving first information sent by a network device, where the first information is used to indicate the first duration.
[0050] Based on the above scheme, the terminal can receive the first information from the network device to obtain the first duration of the uplink transmission timer configured by the network device, and use the second information to enable the network device to control the length of time the terminal continues to perform uplink transmission when the satellite positioning information meets the first condition.
[0051] In combination with some embodiments of the first aspect, in some embodiments, the first information is carried in a system broadcast message or a radio resource control RRC message.
[0052] Based on the above solution, the existing signaling can be directly reused to transmit the first information, effectively reducing signaling overhead.
[0053] In conjunction with some embodiments of the first aspect, in some embodiments, the stop time of the uplink transmission timer includes one of the following:
[0054] The stop time of the uplink transmission timer is the time when the uplink transmission timer times out;
[0055] The stop time of the uplink transmission timer is the time when the satellite positioning information does not meet the first condition;
[0056] The stop time of the uplink transmission timer is the time when the terminal stops the TAT.
[0057] Based on the above scheme, the stop time of the uplink transmission timer can be the time when the uplink transmission timer times out, the time when the satellite positioning information does not meet the first condition, or the time when the terminal stops TAT. In this way, the terminal can stop the uplink transmission timer in time according to the stop time of the uplink transmission timer, thereby reducing the situation where the current state of the terminal is no longer suitable for continuing to perform uplink transmission, and continues to perform uplink transmission during the operation period of the uplink transmission timer.
[0058] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:
[0059] Whether to stop the TAT is determined according to a conflict resolution result of the random access.
[0060] Based on the above solution, since TAT can be used to maintain the validity of the timing advance adjustment amount, the terminal can determine whether to stop TAT based on the conflict resolution result of random access, thereby reducing the terminal from continuing to use an inappropriate timing advance adjustment amount to perform uplink transmission, affecting uplink synchronization.
[0061] In conjunction with some embodiments of the first aspect, in some embodiments, the first condition includes at least one of the following:
[0062] The satellite positioning information of the terminal is invalid;
[0063] The satellite positioning information of the terminal is valid and the accuracy of the satellite positioning information is less than an accuracy threshold.
[0064] Based on the above solution, under normal circumstances, when the satellite positioning information of the terminal is out of date or the satellite positioning information of the terminal is valid and the accuracy of the satellite positioning information is less than the accuracy threshold, the terminal needs to suspend uplink transmission or re-acquire high-precision satellite positioning information before uplink transmission to ensure uplink synchronization. In the embodiment of the present disclosure, when the satellite positioning information of the terminal meets one of the above conditions, the terminal can continue to perform uplink transmission based on the uplink transmission timer, which is beneficial for the terminal to be able to perform uplink transmission in a timely manner even if it cannot re-acquire satellite positioning information that meets the first condition in a timely manner, thereby reducing the delay of uplink transmission.
[0065] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:
[0066] receiving second information sent by a network device, where the second information is used to indicate the accuracy threshold; or,
[0067] The accuracy threshold is determined according to the protocol.
[0068] Based on the above solution, the terminal can receive the second information from the network device or determine the accuracy threshold according to the protocol agreement, so that the terminal can flexibly select the implementation method according to needs.
[0069] In a second aspect, 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:

[0071] In combination with some embodiments of the second aspect, in some embodiments, a time alignment timer TAT of the terminal is in a running state.
[0072] In conjunction with some embodiments of the second aspect, in some embodiments, the method further includes:
[0073] Sending a timing advance command TAC to the terminal; the TAC is used by the terminal to restart the uplink transmission timer when the satellite positioning information meets the first condition and the uplink transmission timer is in operation.
[0074] In conjunction with some embodiments of the second aspect, in some embodiments, the timing duration of the uplink transmission timer includes one of the following:
[0075] A first duration configured by the network device;
[0076] The second duration is determined by predefined rules.
[0077] In combination with some embodiments of the second aspect, in some embodiments, the method further includes: sending first information to the terminal, where the first information is used to indicate the first duration.
[0078] In conjunction with some embodiments of the second aspect, in some embodiments, the stop time of the uplink transmission timer includes one of the following:
[0079] The stop time of the uplink transmission timer is the time when the uplink transmission timer times out;
[0080] The stop time of the uplink transmission timer is the time when the satellite positioning information does not meet the first condition;
[0081] The stop time of the uplink transmission timer is the time when the terminal stops the TAT.
[0082] In conjunction with some embodiments of the second aspect, in some embodiments, the first condition includes at least one of the following:
[0083] The satellite positioning information of the terminal is invalid;
[0084] The satellite positioning information of the terminal is valid and the accuracy of the satellite positioning information is less than an accuracy threshold.
[0085] In combination with some embodiments of the second aspect, in some embodiments, the method further includes: sending second information to the terminal, where the second information is used to indicate the accuracy threshold.

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.
[0125] 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 communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).
[0126] FIG1B shows an NTN communication system, which may include:
[0127] 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);
[0128] Gateway;
[0129] There is a service link (SL) between the terminal and the base station in the air.
[0130] There is a Feeder Link (FL) between the base station in the air and the ground gateway.
[0131] The gateway will be connected to the Data Network (DN).
[0132] 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.
[0133] 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.
[0134] 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.
[0135] The following are descriptions of several NTNs:
[0136] NTN cells may include: terrestrial fixed cells and terrestrial mobile cells.
[0137] The coverage area of a ground-fixed cell does not change over time.
[0138] The area of an earth-moving cell on the ground changes over time.
[0139] 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.
[0140] 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.
[0141] 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:
[0142] S2101: The network device sends a network message to the terminal.
[0143] In some embodiments, the network device broadcasts, multicasts, or unicasts the network message to the terminals.
[0144] In some embodiments, the network message may include the first information and / or the second information.
[0145] In some embodiments, the first information and the second information may be sent to the terminal via different network messages.
[0146] In some embodiments, the first information and the second information may be sent to the terminal via the same network message.
[0147] In some embodiments, the first information is used to indicate a configuration parameter associated with an uplink transmission timer.
[0148] In some embodiments, the first information is used to indicate a first duration configured by the network device for an uplink transmission timer.
[0149] It can be understood that the first information may be configuration information of the uplink transmission timer.
[0150] In some embodiments, the second information is used to indicate information related to the first condition.
[0151] In some embodiments, the second information is used to indicate a threshold associated with the first condition.
[0152] In some embodiments, the second information is used to indicate an accuracy threshold associated with the first condition.
[0153] In some embodiments, the network device broadcasts a system information block carrying the first information and / or the second information.
[0154] In some embodiments, the system information block (SIB) 1 and / or SIB19, etc.
[0155] In some embodiments, SIB19 may also carry ephemeris information of NTN satellites.
[0156] 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).
[0157] It is worth noting that: in some embodiments, S2101 is an optional step. For example, the threshold value related to the first condition and / or the timing duration of the uplink transmission timer can be agreed upon by the protocol. In this case, the network device does not need to send the network message to the terminal.
[0158] 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.
[0159] 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.
[0160] S2102: When the satellite positioning information of the terminal meets the first condition, the terminal determines whether uplink transmission can be performed.
[0161] In some embodiments, the satellite positioning information may include but is not limited to at least one of the following:
[0162] Global Navigation Satellite System (GNSS) position information, which may be position information obtained based on GNSS positioning;
[0163] Beidou Navigation Satellite System (BDS) location information may be location information obtained based on BDS positioning.
[0164] 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.
[0165] 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.
[0166] In some embodiments, the satellite positioning information meeting the first condition may include but is not limited to at least one of the following:
[0167] Satellite positioning information fails;
[0168] The satellite positioning information is valid and the accuracy of the satellite positioning information is less than an accuracy threshold.
[0169] In some embodiments, the accuracy threshold may be an accuracy threshold indicated by the second information.
[0170] It is understood that the accuracy threshold may be configurable by the network device.
[0171] In some embodiments, the accuracy threshold may be determined according to a protocol agreement.
[0172] It is understandable that if the terminal determines the accuracy threshold associated with the first condition by protocol agreement, there is no need for the network device to send the second information, thereby effectively reducing signaling overhead.
[0173] In some embodiments, different accuracy thresholds are associated with different frequency ranges used by a terminal. For example, the frequency ranges of a terminal may include FR1, FR2, and / or FR3. For example, the average frequency in FR2 may be higher than the average frequency in FR1. The average frequency in FR3 may be lower than the frequency range in FR2 and higher than the frequency range in FR1.
[0174] In some embodiments, the magnitude of the average frequency of FR is negatively correlated with the magnitude of the accuracy threshold. For example, the accuracy threshold corresponding to FR1 is 50 meters; and the accuracy threshold corresponding to FR2 is 15 meters.
[0175] It is worth noting that, in the case where the accuracy threshold associated with the first condition is determined according to a protocol agreement, the terminal may select an accuracy threshold corresponding to the frequency range used by the terminal.
[0176] In some embodiments, satellite positioning information failure may include but is not limited to at least one of the following:
[0177] The validity period of satellite positioning information has expired;
[0178] The accuracy of the satellite positioning information is lower than the minimum accuracy threshold for valid satellite positioning information.
[0179] In some embodiments, the accuracy threshold associated with the first condition may be higher than a minimum accuracy threshold for valid positioning information.
[0180] In some embodiments, the accuracy threshold associated with the first condition 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.
[0181] In the embodiment of the present disclosure, the uplink transmission may include uplink transmission of any service data.
[0182] In some embodiments, when the satellite positioning information of the terminal meets the first condition, it is determined whether the terminal can perform uplink transmission according to a time alignment timer (TAT) of the terminal.
[0183] It is understandable that when the satellite positioning information satisfies the first condition, the terminal may determine the current state of its own TAT and determine whether uplink transmission can be performed.
[0184] In some embodiments, when the satellite positioning information of the terminal meets a first condition and the TAT of the terminal is in a running state, it is determined that the terminal is capable of performing uplink transmission.
[0185] In some embodiments, when the satellite positioning information of the terminal meets the first condition and the TAT of the terminal is not running or stops running, it is determined that the terminal is unable to perform uplink transmission.
[0186] The TAT may be a time alignment timer, and the TAT may be started after receiving a timing advance command (TA Command, TAC).
[0187] In some embodiments, the TAT may be a TAT used by the terminal when performing small data transmission.
[0188] In some embodiments, small data transmission (SDT) may include: configured grant (CG) SDT and / or random access channel (RACH) SDT.
[0189] 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.
[0190] The RA-SDT may be an SDT sent using a random access procedure, for example, an SDT sent using Msg1 and / or MsgA.
[0191] In some embodiments, the TAT may be a CG-SDT TAT.
[0192] The TAT may be the TAT used by the terminal when performing CG-SDT in an inactive state. For example, the TAT may be cg-SDT-TimeAli gnmentTimer.
[0193] In some embodiments, the TAT may be a RACH-SDT TAT.
[0194] The TAT may be the TAT used when the terminal performs RACH-SDT in an inactive state.
[0195] In some embodiments, the TAT may be a non-active state positioning POS TAT.
[0196] The TAT may be a TAT used when the terminal sends a positioning sounding reference signal (SRS) in an inactive state. For example, the TAT may be inactivePosSRS-TimeAlignmentTimer.
[0197] In some embodiments, the TAT may be a TAT for random access.
[0198] The TAT may be a TAT for random access performed by the terminal in an inactive state.
[0199] In some embodiments, when the satellite positioning information of the terminal satisfies the first condition and the TAT of the terminal is in a running state, determining the state of the uplink transmission timer of the terminal capable of performing uplink transmission includes one of the following:
[0200] The uplink transmission timer is running;
[0201] The uplink transmission timer is not running;
[0202] The uplink transmission timer stops running.
[0203] Here, the uplink transmission timer not running can be understood as the uplink transmission timer not being started.
[0204] The uplink transmission timer stopping can be understood as the uplink transmission timer stopping after being started and running at least once.
[0205] It is worth noting that when the satellite positioning information of the terminal meets the first condition, if the TAT of the terminal is in a running state and the uplink transmission timer of the terminal is in operation, it is determined that the terminal can perform uplink transmission.
[0206] When the satellite positioning information of the terminal meets the first condition, if the TAT of the terminal is in a running state and the uplink transmission timer of the terminal is not running, it is determined that the terminal can perform uplink transmission.
[0207] When the satellite positioning information of the terminal meets the first condition, if the TAT of the terminal is in a running state and the uplink transmission timer of the terminal stops running, it is determined that the terminal can perform uplink transmission.
[0208] It can be understood that when the satellite positioning information of the terminal meets the first condition and the TAT of the terminal is in the running state, if the state of the uplink transmission timer of the terminal is any of the above states, the terminal can perform uplink transmission when the satellite positioning information meets the first condition.
[0209] In some embodiments, the start time of the uplink transmission timer includes one of the following:
[0210] The start time of the uplink transmission timer is the time when the terminal starts TAT;
[0211] The start time of the uplink transmission timer is the time when the terminal receives the TAC while the uplink transmission timer is running;
[0212] The uplink transmission timer is started at the time when the satellite positioning information of the terminal meets the first condition.
[0213] It is understood that the terminal may start the uplink transmission timer at the start time of the uplink transmission timer. Here, starting the uplink transmission timer may be initially starting the uplink transmission timer. That is, the uplink transmission timer is started when the uplink transmission timer is not running. Alternatively, starting the uplink transmission timer may be restarting the uplink transmission timer. That is, the uplink transmission timer is started when the uplink transmission timer stops running or is running.
[0214] In some embodiments, when the satellite positioning information satisfies the first condition before the TAT is started, the start time of the uplink transmission timer may be the time when the terminal starts the TAT.
[0215] In some embodiments, when the satellite positioning information satisfies the first condition after the TAT is started, the start time of the uplink transmission timer may be the time when the satellite positioning information satisfies the first condition.
[0216] In some embodiments, the timing duration of the uplink transmission timer includes one of the following:
[0217] A first duration configured by the network device;
[0218] The second duration is determined by predefined rules.
[0219] In some embodiments, the first information may be used to indicate a first duration of configuration of the network device.
[0220] It is worth noting that the terminal can receive the first information sent by the network device and determine the timing duration of the uplink transmission timer according to the first duration indicated by the first information. In other words, the terminal can configure the duration of the uplink transmission timer according to the first information.
[0221] In some embodiments, the predefined rules include one of the following:
[0222] The timing duration of TAT is a predetermined value, and the second duration is determined based on the first duration;
[0223] The timing duration of TAT is not a predetermined value, and the second duration is determined according to the remaining duration of TAT.
[0224] It is worth noting that the terminal can configure the duration of the uplink transmission timer according to different timing duration configurations of TAT.
[0225] Here, the predetermined value can be set according to actual needs, and the embodiment of the present disclosure does not limit this. In some embodiments, the predetermined value can be an infinite value (infinity).
[0226] In some embodiments, the stop time of the uplink transmission timer may include one of the following:
[0227] The stop time of the uplink transmission timer is the time when the uplink transmission timer times out;
[0228] The stop time of the uplink transmission timer is the time when the satellite positioning information does not meet the first condition;
[0229] The stop time of the uplink transmission timer is the time when the terminal stops TAT.
[0230] It is understandable that the terminal can stop the uplink transmission timer at the stop moment of the uplink transmission timer. Here, after stopping the uplink transmission timer, the state of the uplink transmission timer is switched from running to stopped.
[0231] S2103: The terminal sends an uplink transmission to the network device based on the uplink transmission timer.
[0232] In some embodiments, the satellite positioning information of the terminal satisfies a first condition, and the terminal performs uplink transmission based on an uplink transmission timer.
[0233] When the satellite positioning information meets the first condition, the terminal can send an uplink transmission to the network device based on the uplink transmission timer.
[0234] In some embodiments, the satellite positioning information of the terminal satisfies the first condition, and the terminal performs uplink transmission during the operation of the uplink transmission timer. In some embodiments, the uplink transmission timer is used to indicate the length of time the terminal can perform uplink transmission when the satellite positioning information satisfies the first condition.
[0235] In some embodiments, if the satellite positioning information satisfies the first condition and the uplink transmission timer is not running, the terminal may start the uplink transmission timer.
[0236] It is understood that, when it is determined that the terminal is capable of performing uplink transmission when the satellite positioning information satisfies the first condition, the terminal may start the uplink transmission timer to perform uplink transmission during the running period of the uplink transmission timer. In this case, the uplink transmission timer is initially started.
[0237] In some embodiments, the satellite positioning information satisfies the first condition and the uplink transmission timer is not running, and the terminal may start the uplink transmission timer at the moment when the satellite positioning information satisfies the first condition.
[0238] In this case, the uplink transmission timer is started at the time when the satellite positioning information of the terminal meets the first condition.
[0239] It is worth noting that the prerequisite for the terminal to perform uplink transmission when the satellite positioning information meets the first condition is that the terminal's TAT is running. If the satellite positioning information meets the first condition and the uplink transmission timer is not running, it means that the terminal's satellite positioning information met the first condition after the TAT was started. In this case, the terminal can determine the start time of the uplink transmission timer as the time when the terminal's satellite positioning information meets the first condition.
[0240] In some embodiments, if the satellite positioning information satisfies the first condition and the uplink transmission timer is running, the terminal may restart the uplink transmission timer.
[0241] It is understandable that when the satellite positioning information meets the first condition and the uplink transmission timer is running, the terminal can restart the uplink transmission timer to adjust the length of time the terminal can perform uplink transmission when the satellite positioning information meets the first condition.
[0242] In some embodiments, the satellite positioning information satisfies the first condition and the uplink transmission timer is running, and the terminal restarts the uplink transmission timer upon receiving the TAC.
[0243] In this case, the start time of the uplink transmission timer may be the time when the terminal receives a timing advance command TAC when the uplink transmission timer is running.
[0244] In some embodiments, if the satellite positioning information satisfies the first condition and the uplink transmission timer stops running, the terminal may restart the uplink transmission timer.
[0245] In some embodiments, the satellite positioning information satisfies the first condition and the uplink transmission timer stops running, and the terminal may restart the uplink transmission timer at the moment of starting the TAT.
[0246] In this case, the start time of the uplink transmission timer is the time when the terminal starts the TAT.
[0247] It is worth noting that, since the uplink transmission timer stops running, it can be understood that the uplink transmission timer stops running after being started and run at least once. In this case, the terminal restarts the uplink transmission timer.
[0248] The satellite positioning information meets the first condition and the uplink transmission timer stops running, indicating that the terminal's TAT is not running, that is, the satellite positioning information has met the first condition before TAT is started. At this time, the terminal can determine the start time of the uplink transmission timer as the time when the terminal starts TAT.
[0249] In some embodiments, after the terminal restarts the uplink transmission timer, the terminal also needs to reconfigure the timing duration of the uplink transmission timer.
[0250] It is worth noting that the timing duration configuration when the terminal restarts the uplink transmission timer is the same as the timing duration configuration when the uplink transmission timer is initially started.
[0251] In some embodiments, the timing duration of the restarted uplink transmission timer may include:
[0252] A first duration configured by the network device;
[0253] The second duration is determined by predefined rules.
[0254] In some embodiments, the predefined rules include one of the following:
[0255] The timing duration of TAT is a predetermined value, and the second duration is determined based on the first duration;
[0256] The timing duration of TAT is not a predetermined value, and the second duration is determined according to the remaining duration of TAT.
[0257] In some embodiments, the uplink transmission timer times out and the terminal stops sending uplink transmissions to the network device.
[0258] It is understandable that since the uplink transmission timer is used to indicate the length of time the terminal can perform uplink transmission when the satellite positioning information meets the first condition, when the uplink transmission timer times out, the uplink transmission timer triggers the terminal to stop performing uplink transmission.
[0259] In some embodiments, the method further comprises:
[0260] The terminal may determine whether to stop TAT according to the conflict resolution result of random access.
[0261] In some embodiments, the terminal may determine whether to stop TAT based on a random access conflict resolution result, which may include one of the following:
[0262] The random access is triggered by RRC connection establishment of the terminal and a conflict resolution result of the random access is failure, stopping the TAT;
[0263] The random access is triggered by a system message request and a conflict resolution result of the random access is successful, and the TAT is stopped.

[0282] A first duration configured by the network device;

[0288] The stop time of the uplink transmission timer is the time when the uplink transmission timer times out;
[0289] The stop time of the uplink transmission timer is the time when the satellite positioning information does not meet the first condition;
[0290] The stop time of the uplink transmission timer is the time when the terminal stops TAT.
[0291] In short, for the optional implementation of S3102, please refer to any optional implementation of the corresponding embodiment of Figure 2.
[0292] S3103: Send an uplink transmission to the network device based on the uplink transmission timer.
[0293] In some embodiments, the satellite positioning information of the terminal satisfies a first condition, and the terminal performs uplink transmission during the running of the uplink transmission timer.
[0294] In some embodiments, if the satellite positioning information satisfies the first condition and the uplink transmission timer is not running, the terminal may start the uplink transmission timer.
[0295] In some embodiments, the satellite positioning information satisfies the first condition and the uplink transmission timer is not running, and the terminal may start the uplink transmission timer at the moment when the satellite positioning information satisfies the first condition.

[0300] In some embodiments, the uplink transmission timer times out and the terminal stops sending uplink transmissions to the network device.
[0301] It is worth noting that: in some embodiments, S3101 is an optional step. For example, the threshold value related to the first condition and / or the timing duration of the uplink transmission timer can be agreed upon by the protocol. In this case, the network device does not need to send the network message to the terminal.
[0302] 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:
[0303] S4101: Send network message.
[0304] In some embodiments, the network message may include the first information and / or the second information.
[0305] The optional step of S4101 here can refer to S2101 of the corresponding embodiment in Figure 2.
[0306] In some embodiments, the first information is used to indicate a configuration parameter associated with an uplink transmission timer.
[0307] In some embodiments, the first information is used to indicate a first duration configured by the network device for an uplink transmission timer.
[0308] In some embodiments, the second information is used to indicate information related to the first condition.
[0309] In some embodiments, the second information is used to indicate a threshold associated with the first condition.
[0310] In some embodiments, the second information is used to indicate an accuracy threshold associated with the first condition.
[0311] In some embodiments, the network device broadcasts a system information block carrying the first information and / or the second information.
[0312] In some embodiments, the system information block (SIB) 1 and / or SIB19, etc.
[0313] In some embodiments, SIB19 may also carry ephemeris information of NTN satellites.
[0314] 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).
[0315] It is worth noting that: in some embodiments, S4101 is an optional step. For example, the threshold value related to the first condition and / or the timing duration of the uplink transmission timer can be agreed upon by the protocol. In this case, the network device does not need to send the network message to the terminal.
[0316] S4102: Receive uplink transmission.
[0317] In some embodiments, the network device receives an uplink transmission sent by the terminal.
[0318] In some embodiments, the network device receives an uplink transmission sent by the terminal when the satellite positioning information meets the first condition.
[0319] In some embodiments, the uplink transmission is sent by the terminal based on an uplink transmission timer.

[0321] The optional step of S4102 here can refer to S2103 of the corresponding embodiment of Figure 2.
[0322] The initial transmission time error for the terminal is Te_NTN=Te+Te_GNSS+Te_SAT.
[0323] 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.
[0324] 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.
[0325] 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.
[0326] 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.
[0327] 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.
[0328] The embodiments of the present disclosure provide a method for uplink transmission, which allows a terminal to perform uplink transmission if the GNSS position information of the UE cannot be located for a short period of time or the positioning accuracy is insufficient.
[0329] 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.
[0330] Furthermore, the terminal can still send uplink transmissions to the NTN cell, which requires the UE to meet at least one of the following conditions:
[0331] The terminal's time alignment timer TAT is in the running state; the terminal's TAT is in the running state, and the uplink transmission timer is also in the running state;
[0332] The terminal's TAT is in the running state, and the uplink transmission timer is not running or is in the stopped state.
[0333] In some embodiments, the start time of the uplink transmission timer includes at least one of the following:
[0334] If the terminal's GNSS location information becomes invalid or the accuracy does not meet the requirements before TAT starts, the uplink transmission timer is started when TAT starts;
[0335] If the moment when the GNSS position information of the terminal becomes invalid or the accuracy does not meet the requirement is after the TAT is started, the uplink transmission timer is started at the moment when the GNSS position information of the terminal becomes invalid or the accuracy does not meet the requirement.
[0336] In some embodiments, the duration of the uplink transmission timer is set to include at least one of the following:
[0337] If the TAT timer duration is configured as non-infinity, the duration of the uplink transmission timer is the remaining TAT duration at the time the timer is started;
[0338] If the TAT timer is configured as infinity, the uplink transmission timer duration is the network configuration value;
[0339] Regardless of the TAT timer duration configuration value, the uplink transmission timer duration is the network configuration value.
[0340] In some embodiments, the duration of the uplink transmission timer may be configured through a system broadcast message or dedicated signaling.
[0341] For example, the system broadcast message is SIB1 or SIB19. The dedicated signaling is RRC Release message or RRC reconfiguration message.
[0342] In some embodiments, if the uplink transmission timer times out, the terminal stops uplink transmission.
[0343] Exemplarily, if the terminal is performing random access and the uplink transmission timer times out, the terminal terminates the random access procedure. Furthermore, illustratively, if the terminal is performing CG-SDT and the uplink transmission timer times out, the terminal terminates CG-SDT. Furthermore, illustratively, if the terminal is performing RA-SDT and the uplink transmission timer times out, the terminal terminates RA-SDT.
[0344] In some embodiments, if the UE receives a timing advance command (TAC) again while the uplink transmission timer is running, the UE performs one of the following:
[0345] The terminal restarts the uplink transmission timer. If the TAT timer duration is configured to be non-infinity, the uplink transmission timer duration is set to the remaining TAT duration.
[0346] The terminal restarts the uplink transmission timer. If the TAT timer duration is configured to infinity, the uplink transmission timer duration is set to the network configuration value.
[0347] The terminal restarts the uplink transmission timer. Regardless of the TAT timer duration configuration value, the uplink transmission timer duration is the network configuration value.
[0348] In some embodiments, the TAT timer may be a CG-SDT TAT timer, a non-active positioning POS TAT timer, or a TAT timer.
[0349] In this embodiment, the CG-SDT TAT timer (cg-SDT-TimeAlignmentTimer) is the TAT timer used when the terminal performs CG-SDT in the inactive state. The inactive positioning POS TAT timer (inactivePosSRS-TimeAlignmentTimer) is the TAT timer used when the terminal transmits a positioning SRS in the inactive state. The TAT timer (timeAlignmentTimer) is the TAT timer used when the terminal performs random access and RACH-based SDT in the inactive state.
[0350] In some embodiments, when the GNSS location information of the terminal becomes valid or the accuracy meets the requirement, the uplink transmission timer is stopped.
[0351] In some embodiments, if the terminal stops the TAT timer, the terminal also stops the uplink transmission timer.
[0352] Embodiment: When contention resolution of a terminal fails (Contention Resolution is considered not successful), the terminal stops TAT and stops the uplink transmission timer at the same time.
[0353] Embodiment: When the contention resolution of the SI request of the terminal is successful (Contention Resolution is considered successful for SI request), the terminal stops the TAT and stops the uplink transmission timer at the same time.
[0354] 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.
[0355] System default values do not require network devices to send network messages. System configuration values may require network devices to configure via network messages.
[0356] Example: For the system default value, the GNSS position information accuracy of FR1 is 50 meters.
[0357] Example: For system preset values, the accuracy of GNSS position information in FR2 and / or FR3 is 15 meters.
[0358] Example: If a system configuration value is used, it can be configured through a system broadcast message or dedicated signaling.

For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods.
