The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0162] 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).

[0163] In the field of communications technology, some Internet of Things (IoT) user equipment (UE) terminals cannot simultaneously receive GNSS signals and transmit and receive communication data. The GNSS position fix obtained by the UE is only valid for a period of time, after which the UE's GNSS becomes outdated. The UE needs to reacquire GNSS signals, but because these terminals do not support simultaneous GNSS reception and data transmission, they can only perform one or the other.

[0164] In order to extend the uplink transmission of such terminals in the present disclosure, after the GNSS of the terminal is outdated, the GNSS is not acquired. Instead, a first indication message is sent to the terminal while the UE still maintains uplink synchronization, instructing the UE to continue uplink transmission within an extension duration time period.

[0165] For example, a timer (such as T390) can be maintained. T390 will start when the GNSS times out. Its value can be equal to the remaining time of the time alignment timer (timeAlignmentTimer, TAT) (if the configured value of TAT is not infinity), or equal to a specified value (such as ul-TransmissionExtensionValue) (if TAT is infinity). In this way, the terminal and network equipment can maintain uplink transmission before T390 times out.

[0166] Alternatively, in order to avoid GNSS timeout, TAT may also timeout, so that when the remaining time (0) of TAT is set to the timing value of T390, the extension of uplink transmission cannot be truly achieved. Alternatively, after the GNSS of the terminal expires, a first timing value greater than 0 can be directly determined. At this first timing value, when the configuration value of TAT is not infinite, it can be the configuration value of TAT, or the remaining time value of TAT after restart, or, when the configuration value of TAT is infinite, it can be a specified value, etc.

[0167] FIG2A is an interactive diagram of a transmission control method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a transmission control method for a terminal 101 and a network device 102, the method comprising:

[0168] Step S2101: The network device 102 sends first indication information.

[0169] In some embodiments, the network device 102 may be a base station, or may be a wireless access point (such as a wireless network access point), etc., which is not limited in the present disclosure.

[0170] In some embodiments, the terms "wireless network access point", "Wireless Fidelity Access Point", "WiFi AP", etc. can be used interchangeably.

[0171] In some embodiments, the first indication information is used to indicate uplink transmission extension, that is, to instruct the terminal to maintain uplink transmission for a period of time after the GNSS expires.

[0172] In some embodiments, terms such as "first indication information", "ul-TransmissionExtensionEnabled", "ul-TransmissionExtensionEnabled MAC CE", "UL transmission Extension", and "UL transmission Extension MAC CE" can be used interchangeably.

[0173] In some embodiments, terms such as "MAC CE", "media access control element", "media access control element", and "media access control element" can be used interchangeably.

[0174] In some embodiments, the network device 102 may send the first indication information via a media access control (MAC) packet data unit (PDU).

[0175] In some embodiments, the first indication information is a MAC CE in a MAC PDU.

[0176] In some embodiments, the MAC CE is a 0-byte MAC CE.

[0177] In some embodiments, the terminal 101 receives first indication information.

[0178] In step S2102 , the terminal 101 receives the first indication information, and the configured value of the time alignment timer TAT is not infinite, and determines the configured value of TAT as the first timing value.

[0179] In step S2103 , the terminal 101 and the network device 102 set the timing value of the first timer to the first timing value.

[0180] The timing value of the first timer is greater than zero.

[0181] In some embodiments, the terms "first timer", "T390" and the like can be replaced with each other. It should be noted that the first timer is a timer set to control the extended duration of uplink transmission, and this disclosure does not limit its name.

[0182] In some embodiments, terms such as "infinity" and "infinity" can be used interchangeably.

[0183] In some embodiments, after sending the first indication information, the network device 102 may determine the configuration value of the TAT associated with the terminal as the first timing value.

[0184] In some embodiments, the terminal 101 receives the first indication information via a MAC PDU.

[0185] In some embodiments, the configuration value of TAT may be agreed upon by a protocol, or may be configured by the network device 102 for the terminal device 101, which is not limited in this disclosure.

[0186] Step S2104: Before the first timer times out, the terminal 101 and the network device 102 maintain uplink transmission.

[0187] The transmission control method according to the embodiment of the present disclosure may include at least one of steps S2101 to S2104. For example, steps S2102 and S2104 may be implemented as independent embodiments, and steps S2102, 2103, and 2104 may be implemented as independent embodiments, but the present disclosure is not limited thereto.

[0188] 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.

[0189] In the embodiments of the present disclosure, each step can also be implemented independently.

[0190] In this embodiment, the network device sends first indication information to the terminal to instruct it to extend uplink transmission. If the configured TAT value is not infinite, the terminal and the network device may determine the configured TAT value as a first timer value and maintain uplink transmission within the first timer value. This ensures that GNSS outdatedness is prevented, maintains uplink transmission for a certain period of time, extends the uplink transmission maintenance time, and improves the reliability of uplink transmission.

[0191] FIG2B is an interactive diagram of a transmission control method according to an embodiment of the present disclosure. As shown in FIG2B , the embodiment of the present disclosure relates to a transmission control method for terminal 101 and network device 102, the method comprising:

[0192] In step S2201, the network device 102 sends first indication information and second indication information.

[0193] The second indication information is used to instruct restarting TAT.

[0194] In some embodiments, terms such as "second indication information", "TA command", "TA command MAC CE" and the like can be used interchangeably.

[0195] In some embodiments, the network device 102 may send the first indication information and the second indication information simultaneously.

[0196] In some embodiments, the network device 102 may send the first indication information and the second indication information via the same MAC PDU. That is, the first indication information and the second indication information may be different MAC CEs in the same MAC PDU.

[0197] In some embodiments, the network device 102 may send the second indication information before determining to send the first indication information.

[0198] In some embodiments, network device 102 may send the second indication information at a specified time before sending the first indication information. For example, if the first indication information is sent at a first time, the second indication information may be sent at a second time whose time difference from the first time is less than a first duration threshold and greater than a second duration threshold. The first duration threshold is less than a configured value of TAT, and the second duration threshold is a value greater than the time required for the terminal to respond to the second indication information.

[0199] That is, when the network device 102 sends the first indication information and the second indication information, it is necessary to ensure that the terminal 101 has completed the operation indicated by the second indication information when receiving the first indication information, and the current remaining time value of TAT is greater than 0.

[0200] Step S2202: When the terminal 101 receives the first indication information and the second indication information and the configured value of the TAT is not infinite, the terminal 101 restarts the TAT and determines the remaining time value of the restarted TAT as the first timing value.

[0201] In step S2203 , the terminal 101 and the network device 102 set the timing value of the first timer to the first timing value.

[0202] In some embodiments, the terminal 101 may receive the first indication information and the second indication information simultaneously.

[0203] In some embodiments, the terminal 101 may also receive the second indication information first and then receive the first indication information.

[0204] In some embodiments, the first indication information and the second indication information may be carried in different MAC PDUs.

[0205] In some embodiments, the terminal 101 may simultaneously receive the first indication information and the second indication information through the same MAC PDU.

[0206] In some embodiments, when the terminal 101 receives the first indication information and the second indication information at the same time, it can first respond to the second indication information to restart TAT, and then respond to the first indication information to determine the remaining time value of the restarted TAT as the timing value of the first timer.

[0207] Step S2204: Before the first timer times out, the terminal 101 and the network device 102 maintain uplink transmission.

[0208] For a detailed description of step S2204, reference may be made to step S2104 in the embodiment shown in FIG2A , which will not be repeated here.

[0209] The transmission control method according to the embodiment of the present disclosure may include at least one of steps S2201 to S2204. For example, steps S2202 and S22043 may be implemented as independent embodiments, and steps S2202, S2203, and S2204 may be implemented as independent embodiments, but are not limited thereto.

[0210] 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.

[0211] In the embodiments of the present disclosure, each step can also be implemented independently.

[0212] In this embodiment, the network device sends a first indication message indicating an uplink transmission extension and a second indication message indicating a restart of the TAT to the terminal. If the configured TAT value is not infinite, the terminal can restart the TAT and set the remaining time of the restarted TAT as the timing value of the first timer. The terminal then maintains uplink transmission until the first timer expires. This ensures that GNSS outages are prevented, maintains uplink transmission for a certain period of time, extends the uplink transmission maintenance time, and improves the reliability of uplink transmission.

[0213] FIG2C is an interactive diagram of a transmission control method according to an embodiment of the present disclosure. As shown in FIG2C , the embodiment of the present disclosure relates to a transmission control method for terminal 101 and network device 102, the method comprising:

[0214] Step S2301: The network device 102 sends first indication information.

[0215] For a detailed description of step S2301, reference may be made to step S2101 in the embodiment shown in FIG2A or to step S2201 in the embodiment shown in FIG2B, which will not be repeated here.

[0216] In step S2302 , the terminal 101 receives the first indication information but does not receive the second indication information, and the configured value of the TAT is infinite. The TAT is not restarted, and the remaining time value of the TAT that is not restarted is determined as the first timing value.

[0217] In step S2303, the terminal 101 and the network device 102 set the timing value of the first timer to the first timing value.

[0218] In some embodiments, network device 102 does not simultaneously send the second indication information when sending the first indication information, resulting in terminal 101 not receiving the second indication information when receiving the first indication information. Alternatively, terminal 101 does not simultaneously receive the second indication information when receiving the first indication information due to some other reason. In this case, since TAT cannot be restarted, the current remaining time value of TAT can be determined as the timing value of the first timer, thereby ensuring a certain degree of extension of uplink transmission as much as possible.

[0219] Step S2304: Before the first timer times out, the terminal 101 and the network device 102 maintain uplink transmission.

[0220] For a detailed description of step S2304, please refer to step S2104 in the embodiment shown in FIG2A , which will not be repeated here.

[0221] The transmission control method according to the embodiment of the present disclosure may include at least one of steps S2301 to S2304. For example, steps S2302 and 2304 may be implemented as independent embodiments, and steps S2302, 2303, and 2304 may be implemented as independent embodiments, but are not limited thereto.

[0222] 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.

[0223] In the embodiments of the present disclosure, each step can also be implemented independently.

[0224] In this embodiment, if the configured value of TAT is not infinite, then upon receiving the first indication information but not the second indication information, the terminal may not restart TAT. Instead, the remaining time of the TAT after the restart is determined as the timing value of the first timer, and uplink transmission is maintained until the first timer expires. This ensures that GNSS outages are avoided, and uplink transmission can be maintained for a certain period of time as much as possible, thereby extending the uplink transmission maintenance time and improving the reliability of uplink transmission.

[0229] In step S2403 , the terminal 101 and the network device 102 set the timing value of the first timer to the first timing value.

[0230] In some embodiments, when the configuration value of the time alignment timer TAT is infinite, the terminal 101 and the network device 102 may also determine a specified value as the timing value of the first timer. For example, the uplink transmission extension value may be determined as the timing value of the first timer, which is not limited in this disclosure.

[0231] In some embodiments, terms such as "uplink transmission extension value", "UL Transmission Extension Value", and "uplink Transmission Extension Value" can be used interchangeably.

[0232] In some embodiments, when the terminal 101 receives the first indication information and the configured value of TAT is infinite, the terminal 101 can determine the designated value as the timing value of the first timer regardless of whether the second indication information is received.

[0233] Step S2404: Before the first timer expires, the terminal 101 and the network device 102 maintain uplink transmission.

[0234] For a detailed description of step S2404, please refer to step S2104 in the embodiment shown in FIG2A , which will not be repeated here.

[0235] The transmission control method according to the embodiment of the present disclosure may include at least one of steps S2401 to S2404. For example, steps S2402 and 2404 may be implemented as independent embodiments, and steps S2402, 2403, and 2404 may be implemented as independent embodiments, but are not limited thereto.

This ensures that GNSS is not outdated, and that uplink transmission can be maintained for a certain period of time as much as possible, thereby extending the maintenance time of uplink transmission and improving the reliability of uplink transmission.

[0240] In step S2501, the network device 102 sends first indication information and second indication information.

[0241] In step S2502 , the terminal 101 receives the first indication information, and in response to the configuration value of the TAT not being infinite and the MAC PDU including the first indication information including the second indication information, restarts the TAT.

[0242] Step S2503: Determine the remaining time value of the TAT after the restart as the first timing value.

As shown in FIG5 , the embodiment of the present disclosure relates to a transmission control method for a communication system, including: a terminal 101 and a network device 102, and the method includes:

[0335] Step S5101: The network device 102 sends first indication information to the terminal to determine a first timing value associated with the terminal.

[0336] Step S5102: Terminal 101 receives the first indication information and determines the first timing value.

[0337] In step S5103 , the network device 102 and the terminal 101 maintain uplink transmission of the terminal within the first timing value.

[0338] For a detailed description of steps S5101 - S5103 , please refer to the above embodiment description.

[0339] In the disclosed embodiments, after transmitting the first indication information, the network device and the terminal can determine a first timing value and maintain uplink transmission within the first timing value. This ensures that GNSS outdatedness is avoided, and uplink transmission can be maintained for a certain period of time as much as possible, thereby extending the uplink transmission maintenance time and improving the reliability of uplink transmission.

[0340] The following is an exemplary introduction to the above method.

[0341] This disclosure aims to solve the problem of how to ensure reliable extension of UE uplink transmission after the UE's GNSS timeout. The optional implementation solutions are as follows:

[0342] Solution 1: For scenarios where the configured value of TAT (timeAlignmentTimer) is not infinity, when the UE receives the UL Transmission Extension MAC CE, the UE sets the value of T390 to the configured value of TAT.

[0343] Solution 2: For scenarios where the configured TAT value is not infinity, the network device (e.g., base station) sends a second indication message (e.g., TA command MAC CE) simultaneously with the UL Transmission Extension MAC CE. Upon receiving both the UL Transmission Extension MAC CE and the TA command MAC CE, the UE first executes the TA command MAC CE and then the UL Transmission Extension MAC CE.

[0344] That is, after receiving the UL transmission extension MAC CE, the UE first determines whether to restart T390. If T390 is to be restarted, T390 is restarted according to the first timing value.

[0345] Optionally, the UL transmission Extension MAC CE is a 0-byte MAC CE.

[0346] Optionally, after receiving the UL transmission Extension MAC CE, if the configured value of TAT is not infinity, the UE restarts T390 and sets the value of T390 to the configured value of TAT.

[0347] Optionally, after receiving the UL transmission Extension MAC CE, if the configured value of TAT is not infinity, if the UE receives the TA command MAC CE at the same time, the UE first executes the TA command MAC CE, and then the UE executes the UL transmission Extension MAC CE, restarts T390, and sets the value of T390 to the remaining value of TAT.

[0348] Optionally, the UL transmission Extension MAC CE and the TA command MAC CE are received simultaneously, including receiving both in the same MAC PDU.

[0349] Optionally, after receiving the UL transmission Extension MAC CE, if the configured value of TAT is not infinity and if the UE does not receive the TA command MAC CE at the same time, the UE does not restart T390, that is, continues to run T390.

[0350] Optionally, after receiving the UL transmission Extension MAC CE, if the configured value of TAT is infinity, the UE restarts T390 and sets the value of T390 to a specified value, such as ul-TransmissionExtensionValue.
