Description

Communication methods and devices

[0001] This application claims priority to Chinese Patent Application No. 202510134631.0, filed with the State Intellectual Property Office of China on February 6, 2025, entitled "Communication Method and Apparatus", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of wireless communication technology, specifically to a communication method and apparatus. Background Technology

[0003] In some communication systems, terminals operate in half-duplex mode. The protocol stipulates that after a period of continuous uplink transmission (e.g., 256 milliseconds), the terminal must enter an uplink transmission gap (UL Tx gap). Upon entering the gap, the terminal must cease uplink transmission and continuously receive downlink signals for a period of time (e.g., 40 milliseconds).

[0004] If the time when the terminal enters the interval state happens to fall within the duration of the terminal's uplink transmission, the terminal will enter the interval state after transmitting a portion of the data, pausing the uplink transmission. After the interval state ends, the terminal will continue uplink transmission of the remaining data that was not previously transmitted.

[0005] If the terminal has entered an interval state and suspended uplink transmission, but the network device is unaware that the terminal has suspended uplink transmission and still demodulates the terminal's data, it will introduce noise, reduce the demodulation performance of the network device, and waste the processing resources of the network device. Summary of the Invention

[0006] This application provides a communication method and apparatus. By actively reporting uplink transmission interval information to the network device, the terminal can alleviate the degradation in demodulation performance and waste of processing resources caused by the network device's lack of awareness that the terminal has paused uplink transmission. The technical solution is as follows.

[0007] Firstly, a communication method is provided. This method can be executed by a terminal, or by a component configured in the terminal (such as a circuit, chip, or chip system), or by a logic module or software capable of implementing all or part of the terminal's functions. This application does not limit this. The following description uses a terminal as an example. The method includes:

[0008] The terminal determines that it needs to enter an interval state during the duration of its uplink transmission to the network device; the terminal obtains uplink transmission interval information, which indicates the time point at which the terminal enters the interval state; before entering the interval state, the terminal sends the uplink transmission interval information to the network device.

[0009] By using the above method, since the terminal notifies the network device of the uplink transmission interval information in advance before entering the uplink transmission interval state, the network device can know when the terminal will enter the interval state based on the uplink transmission interval information. As a result, it can stop demodulating the terminal's data when the terminal enters the interval state, thereby reducing the risk of network device demodulation performance degradation and processing resource waste caused by the network device still demodulating the terminal's data when the terminal enters the interval state.

[0010] In one implementation, the uplink transmission interval information includes the time point at which the terminal enters the interval state; or,

[0011] The uplink transmission interval information includes the time difference between the time the uplink transmission interval information was sent and the time the terminal entered the interval state; or, the uplink transmission interval information includes the duration for which the terminal has been continuously transmitting uplink data at the time the uplink transmission interval information was sent.

[0012] The above implementation supports multiple forms of expression for uplink transmission interval information. For example, the terminal can notify the network device of the time point when it enters the interval state, or the terminal can notify the network device of the duration of continuous uplink transmission, or the terminal can notify the network device of how long after sending the uplink transmission interval information the terminal will enter the interval state. This makes it suitable for a wider range of application scenarios.

[0013] In one implementation, the terminal sends the uplink transmission interval information to the network device, including: the terminal sends a MAC CE to the network device, the MAC CE including the uplink transmission interval information.

[0014] Considering that MAC CE can be transmitted along with service data, using MAC CE to carry uplink transmission interval information requires less resources to send uplink transmission interval information, making it more suitable for scenarios where uplink service data is transmitted.

[0015] In one implementation, the MAC CE also includes a Logical Channel Group Identifier (LCG ID).

[0016] Since the protocol specifies that the content following the LCG ID is information identifying the transmission interval, sending the uplink transmission interval information together with the LCG ID to the network device achieves good compatibility with existing protocols and reduces implementation complexity.

[0017] In one implementation, the method further includes: the terminal sending the longest duration for which the terminal can continuously transmit upstream to the network device.

[0018] By announcing the maximum duration of continuous uplink transmission that the terminal can sustain, the network device can determine the timing for the terminal to enter the interval state based on the terminal's already sustained uplink transmission duration and the maximum duration it can sustain. In particular, even if the terminal enters the interval state continuously for k milliseconds instead of the protocol-specified 256 milliseconds, it can still report k to the base station, thus supporting more scenarios where terminals need to enter the interval state and improving flexibility.

[0019] In one implementation, the terminal sends the uplink transmission interval information to the network device, including: the terminal sends the uplink transmission interval information to the network device at a target time point, the target time point being before the time point when the terminal enters the interval state, and the time difference between the target time point and the time point when the terminal enters the interval state being greater than or equal to the sum of the transmission delay between the terminal and the network device and the demodulation delay of the network device.

[0020] Considering that the uplink transmission interval information takes a certain amount of time to be transmitted from the terminal to the network device, and the network device also needs a certain amount of time to demodulate the uplink transmission interval information to know when the terminal enters the interval state, the timing of the terminal sending the uplink transmission interval information is designed to be sent with an advance transmission delay plus a demodulation delay. This avoids the risk of the terminal's data being demodulated when the terminal has already entered the interval state, but the network device has not yet received the uplink transmission interval information or has not yet demodulated the uplink transmission interval information.

[0021] In one implementation, the duration of the uplink transmission is the duration of an orthogonal coverage code group (OCC group). The terminal determines that it needs to enter an interval state within the duration of its uplink transmission to the network device. This includes: the terminal determining that it needs to enter an interval state within the duration of the OCC group based on the duration of its continuous uplink transmission, the duration of the OCC group, and the longest duration that the terminal can continuously transmit uplink.

[0022] Since the probability of a terminal entering an interval state is relatively high during the period when the terminal is transmitting OCC group, the time point when the terminal enters the interval state within the duration of the OCC group can be determined relatively accurately based on the duration of the terminal's continuous uplink transmission, the duration of the OCC group, and the longest duration that the terminal can continuously transmit uplink.

[0023] In one implementation, the terminal sends the uplink transmission interval information to the network device, including: the terminal sending first uplink transmission interval information to the network device; if no acknowledgment message is received from the network device regarding the first uplink transmission interval information, the terminal sending second uplink transmission interval information to the network device.

[0024] Wherein, the first uplink transmission interval information includes the time difference between the time point when the first uplink transmission interval information is sent and the time point when the terminal enters the interval state, and the second uplink transmission interval information includes the time difference between the time point when the second uplink transmission interval information is sent and the time point when the terminal enters the interval state; or, the first uplink transmission interval information includes the duration for which the terminal has been continuously transmitting uplink information at the time point when the first uplink transmission interval information is sent, and the second uplink transmission interval information includes the duration for which the terminal has been continuously transmitting uplink information at the time point when the second uplink transmission interval information is sent.

[0025] Considering that uplink transmission interval information may fail to be transmitted successfully on the first attempt, the terminal improves the transmission success rate by transmitting the uplink transmission interval information multiple times. Furthermore, considering that different uplink transmission interval information is transmitted at different times, the later the transmission time of the uplink transmission interval information is, the closer it is to the time when the terminal enters the interval state. The specific value of the uplink transmission interval information transmitted by the terminal each time is different, allowing the uplink transmission interval information to more accurately indicate the time when the terminal enters the interval state.

[0026] Secondly, a communication method is provided. This method can be executed by a network device, or by a component (such as a circuit, chip, or chip system) configured in the network device, or by a logic module or software capable of implementing all or part of the functions of the network device. This application does not limit this. The following description uses a network device (such as a satellite) as an example. The method includes: the network device receiving uplink transmission interval information from a terminal; the network device obtaining, based on the uplink transmission interval information, the time point at which the terminal enters the interval state; and the network device canceling demodulation of the terminal's data at the time point at which the terminal enters the interval state.

[0027] In one implementation, the network device obtains the time point at which the terminal enters the interval state based on the uplink transmission interval information, including: the network device obtaining the time point at which the terminal enters the interval state carried by the uplink transmission interval information; or, the network device obtaining the time point at which the terminal enters the interval state based on the reception time point of the uplink transmission interval information and the time difference carried by the uplink transmission interval information; or, the network device obtaining the time point at which the terminal enters the interval state based on the duration of continuous uplink transmission carried by the uplink transmission interval information and the longest duration at which the terminal can continuously transmit uplink information.

[0028] In one implementation, before the network device receives uplink transmission interval information from the terminal, the method further includes: the network device allocating an uplink transmission duration segment for the terminal, wherein the time point at which the terminal enters the interval state falls within the uplink transmission duration segment.

[0034] In one implementation, a transceiver module is used to send a MAC CE to the network device, the MAC CE including the uplink transmission interval information.

[0035] In one implementation, the MAC CE also includes a Logical Channel Group Identifier (LCG ID).

[0036] In one implementation, the transceiver module is also used to send the network device the longest duration for which the terminal can continuously transmit upstream.

[0037] In one implementation, the transceiver module is used to send the uplink transmission interval information to the network device at a target time point. The target time point is before the time point when the terminal enters the interval state, and the time difference between the target time point and the time point when the terminal enters the interval state is greater than or equal to the sum of the transmission delay between the terminal and the network device and the demodulation delay of the network device.

[0038] In one implementation, the duration of the uplink transmission is the duration of the orthogonal coverage code group (OCC group). The processing module is used to determine, based on the duration of the uplink transmission that the terminal has been continuously transmitting, the duration of the OCC group, and the longest duration that the terminal can continuously transmit uplink, whether the terminal needs to enter an interval state within the duration of the OCC group.

[0039] In one implementation, the transceiver module is used to send a first uplink transmission interval information to the network device; if no acknowledgment message is received from the network device regarding the first uplink transmission interval information, it sends a second uplink transmission interval information to the network device.

[0040] Wherein, the first uplink transmission interval information includes the time difference between the time point when the first uplink transmission interval information is sent and the time point when the terminal enters the interval state, and the second uplink transmission interval information includes the time difference between the time point when the second uplink transmission interval information is sent and the time point when the terminal enters the interval state; or, the first uplink transmission interval information includes the duration for which the terminal has been continuously transmitting uplink information at the time point when the first uplink transmission interval information is sent, and the second uplink transmission interval information includes the duration for which the terminal has been continuously transmitting uplink information at the time point when the second uplink transmission interval information is sent.

[0069] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0070] The following examples illustrate the application scenarios provided in the embodiments of this application.

[0071] This application applies to a narrowband Internet of Things (NB-IoT) system. The NB-IoT system includes terminals and network devices. For example, please refer to Figure 1, which is a schematic diagram of the architecture of an NB-IoT system provided in this application embodiment. The system shown in Figure 1 includes a base station 1 and a terminal 2. This NB-IoT system is, for example, a non-terrestrial network (NTN) system. Base station 1 is, for example, a base station (gNodeB or gNB) in new radio (NR). Terminal 2 is, for example, an IoT terminal.

[0072] In this embodiment, the terminal needs to enter the uplink transmission interval state (UL Tx gap) after continuously uplinking data to the network device for a period of time. Taking the NB-IoT system as an example, in the NB-IoT system, the terminal operates in half-duplex mode. According to the protocol, after the terminal performs uplink transmission for 256 milliseconds, it must enter the uplink transmission interval state (UL Tx gap). From the moment it enters the interval state, the terminal must stop uplink transmission and continuously receive downlink signals for 40 milliseconds.

[0073] This situation, where a terminal enters an interval state during continuous uplink transmission, can have negative consequences when multiple terminals are transmitting Orthogonal Cover Code Groups (OCC groups). For example, if a terminal's UL Tx gap happens to occur within an OCC group, and that terminal performs a UL Tx gap after transmitting a portion of the OCC group's time slots, it will interfere with other terminals in that OCC group. In this case, the terminal should stop transmitting the entire OCC group and wait until it is no longer in a UL Tx gap state before resuming transmission of the OCC group.

[0074] If the terminal stops transmitting the entire OCC group due to entering the UL Tx gap state, but the base station is unaware that the terminal has stopped transmitting, and the base station still demodulates the terminal's uplink data, this will introduce noise and reduce the base station's demodulation performance.

[0075] Therefore, the base station needs to know when the terminals participating in the OCC group will perform the UL Tx gap. If the number of terminals served by the base station is very large (e.g., in an NTN system), the base station needs to maintain the uplink transmission time information of a large number of terminals, which is a very high maintenance workload for a system with a large number of terminals.

[0076] The method flow of the embodiments of this application is illustrated below.

[0077] Figure 2 is a flowchart of a communication method provided in an embodiment of this application. In some embodiments, the method shown in Figure 2 is applied to the system shown in Figure 1. For example, the terminal in the method shown in Figure 2 is terminal 2 in Figure 1, and the network device in the method shown in Figure 2 is base station 1 in Figure 1. The method shown in Figure 2 includes the following steps S210 to S260.

[0078] In step S210, the terminal determines that it needs to enter an interval state during the duration of the uplink transmission from the terminal to the network device.

[0079] The interval state, also known as the gap state, is a state in which the terminal suspends continuous uplink transmission. Optionally, the terminal receives downlink signals during the interval state.

[0080] In some implementations, if the duration of the uplink transmission exceeds the maximum duration for which the terminal can continuously transmit uplinks, the terminal determines that it needs to enter an interval state during the uplink transmission duration. For example, the terminal determines that it needs to enter an interval state during the uplink transmission duration based on the duration of its already continuous uplink transmission, the duration for which it needs to continue transmitting uplinks, and the maximum duration for which it can continuously transmit uplinks. For instance, if the maximum duration for which the terminal can continuously transmit uplinks is k milliseconds, and the terminal has already continuously transmitted uplinks for m milliseconds, and the terminal still needs to transmit uplinks for n milliseconds, if (m+n)>k, the terminal determines that it needs to enter an interval state during the subsequent uplink transmission duration.

[0081] Taking the OCC group scenario as an example, the terminal is assigned an OCC group. The OCC group is used for repeated transmission on the Narrowband Physical Uplink Shared Channel (NPUSCH). The duration of the uplink transmission is the duration of the OCC group. Based on the duration of the terminal's continuous uplink transmission, the duration of the OCC group, and the longest duration that the terminal can continuously transmit uplink, the terminal determines that within the duration of the OCC group, the terminal needs to enter the interval state and stop NPUSCH repetition transmission.

[0082] As a specific example, the longest duration for continuous uplink transmission by the terminal is 256 milliseconds, and the duration of the OCC group is 300 milliseconds. The terminal has already continuously transmitted the OCC group data for 100 milliseconds and still needs to transmit the OCC group for another 200 milliseconds. The terminal determines that in the 156th millisecond of the subsequent 200 milliseconds of uplink transmission, the longest duration for continuous uplink transmission has been reached, and it needs to enter the interval state. Therefore, the subsequent process of this embodiment is triggered to report the uplink transmission interval information to the network device.

[0083] Step S220: The terminal obtains the uplink transmission interval information.

[0084] Uplink transmission interval information indicates the time point at which the terminal enters the interval state, which can also be understood as the time point at which the terminal stops continuous uplink transmission. Uplink transmission interval information comes in many forms; examples are given below.

[0085] The first type of uplink transmission interval information includes the start time of the terminal entering the interval state.

[0086] The time point at which the terminal enters the interval state is, for example, the time point at which the terminal stops continuous uplink transmission, such as the time point at which the terminal stops OCC NPUSCH repetition transmission. In some implementations, the uplink transmission interval information includes a timeslot number, which is used to identify the timeslot in which the terminal enters the interval state.

[0087] The second type of uplink transmission interval information includes the time difference between the time point when the uplink transmission interval information is sent and the time point when the terminal enters the interval state.

[0088] For example, the terminal enters the interval state at time t1, and the terminal sends uplink transmission interval information to the network device at time t2. The uplink transmission interval information includes (t1-t2).

[0089] For example, the uplink transmission interval information includes the number of time slots that are delayed after the transmission time of the uplink transmission interval information. This number of time slots indicates that the terminal will enter the interval state after the transmission time of the uplink transmission interval information has been transmitted and after the number of time slots has elapsed.

[0090] For example, the uplink transmission interval information includes the number of milliseconds that the uplink transmission interval information is delayed from its transmission time. This number of milliseconds indicates that the terminal will enter the interval state after sending the uplink transmission interval information, after that number of milliseconds. For instance, if the uplink transmission interval information includes 13, it indicates that the terminal enters the interval state and stops uplink transmission after 13 milliseconds.

[0091] The third type of uplink transmission interval information includes the duration of uplink transmission that the terminal has been continuously transmitting at the time point when the uplink transmission interval information was sent.

[0092] For example, the uplink transmission interval information includes the number of milliseconds the terminal has been continuously transmitting uplink data at the time the uplink transmission interval information was sent. As another example, the uplink transmission interval information includes the number of time slots the terminal has been continuously transmitting uplink data at the time the uplink transmission interval information was sent. For instance, if the uplink transmission interval information includes 200, it indicates that the terminal has been continuously transmitting uplink data for 200 milliseconds.

[0093] In step S230, before entering the interval state, the terminal sends uplink transmission interval information to the network device.

[0094] If a terminal determines that it will enter an interval state during the duration of an uplink transmission, it will notify the network device in advance when it will enter the interval state by sending uplink transmission interval information.

[0095] Regarding the specific timing of the terminal sending uplink transmission interval information, in some implementations, the terminal sends the uplink transmission interval information to the network device at a target time point. The target time point is before the time the terminal enters the interval state, and the time difference between the target time point and the time the terminal enters the interval state is greater than or equal to the sum of the transmission delay between the terminal and the network device and the demodulation delay of the network device. For example, if the starting time point for the terminal to enter the interval state is t1, the transmission delay between the terminal and the network device is t2, the demodulation delay of the network device is t3, and the target time point for the terminal to send the uplink transmission interval information is before (t1-t2-t3). Considering that after the terminal sends the uplink transmission interval information, it takes a certain amount of time for the uplink transmission interval information to be transmitted from the terminal to the network device, and the network device also needs a certain amount of time to demodulate the uplink transmission interval information after receiving it, by sending the uplink transmission interval information by shifting forward by the sum of the transmission delay and demodulation delay based on the time point of entering the interval state, it is equivalent to reserving the transmission delay and demodulation delay in advance, thereby increasing the probability that the network device knows the time point of the terminal entering the interval state before the terminal enters the interval state.

[0096] In one possible implementation, to address the sources of transmission latency between a terminal and a network device, the network device sends its location to the terminal. The terminal determines the distance between itself and the network device based on its own location and the location of the network device. Finally, the terminal determines the transmission latency between itself and the network device based on the distance and the signal transmission speed.

[0097] Regarding the sources of demodulation latency in network devices, in one possible implementation, the terminal obtains the demodulation latency of the network device from configuration information, which can be sent to the terminal by the network device or obtained by the user through configuration operations on the terminal.

[0098] In some implementations, the terminal sends uplink transmission interval information during uplink transmission. For example, the terminal sends uplink transmission interval information when sending service data to a network device. For example, the terminal sends uplink transmission interval information on the NPUSCH during NPUSCH repetition transmission.

[0099] In step S240, the network device receives uplink transmission interval information from the terminal.

[0100] In step S250, the network device obtains the time point at which the terminal enters the interval state based on the uplink transmission interval information.

[0101] If the uplink transmission interval information includes the start time of the terminal entering the interval state, the network device can obtain the time of the terminal entering the interval state by demodulating the uplink transmission interval information.

[0102] When the uplink transmission interval information includes the time difference between the transmission time of the uplink transmission interval information and the time when the terminal enters the interval state, the network device determines the time when the terminal enters the interval state based on the reception time of the uplink transmission interval information and the time difference in the uplink transmission interval information. For example, if the network device receives the uplink transmission interval information at time t1, and the time difference in the uplink transmission interval information is t2, the network device determines that the terminal enters the interval state at (t1+t2).

[0103] When the uplink transmission interval information includes the duration of continuous uplink transmission by the terminal at the time the uplink transmission interval information was sent, the network device determines the time point when the terminal enters the interval state based on the duration of continuous uplink transmission already completed by the terminal and the longest duration the terminal can continuously transmit uplink. For example, the longest duration the terminal can continuously transmit uplink is k milliseconds, the terminal has been continuously transmitting uplink for m milliseconds when sending the uplink transmission interval information, the uplink transmission interval information includes m, and the network device receives the uplink transmission interval information at time point t1. The network device determines the time difference (km) between the longest duration k the terminal can continuously transmit uplink and the duration m the terminal has been continuously transmitting uplink, where (km) is the duration of subsequent continuous uplink transmission after receiving the uplink transmission interval information. The network device determines the sum of the time point when the uplink transmission interval information was received and the duration of subsequent continuous uplink transmission (t1+km) as the time point when the terminal enters the interval state.

[0104] As a specific example, the longest duration for which a terminal can continuously transmit uplink data is 256 milliseconds. The uplink transmission interval information sent by the terminal includes 200, indicating that the terminal has been continuously transmitting uplink data for 200 milliseconds. Based on the 200 in the uplink transmission interval information, the network device determines that the terminal can continue to transmit uplink data for a maximum of 256-200=56 milliseconds. Therefore, the network device demodulates the terminal's data in the 56th millisecond after receiving the uplink transmission interval information.

[0105] Regarding the methods by which network devices obtain the longest continuous uplink transmission duration that a terminal can transmit data for, in some implementations, the longest continuous uplink transmission duration is a value specified in the standard protocol. For example, the longest continuous uplink transmission duration is 256 milliseconds. In other implementations, the terminal sends the longest continuous uplink transmission duration to the network device. For example, if the terminal does not enter the interval state after continuous uplink transmission for 256 milliseconds as specified in the standard protocol, but instead enters the interval state after continuous uplink transmission for k milliseconds, then the terminal sends k to the network device.

[0106] The longest duration of continuous uplink transmission and the uplink transmission interval information that the terminal can transmit continuously can be sent sequentially or in parallel. In this embodiment, there is no limitation on the order of sending the longest duration of continuous uplink transmission and the uplink transmission interval information.

[0107] In step S260, the network device cancels the uplink transmission of data from the demodulation terminal at the time point when the terminal enters the interval state.

[0108] In some implementations, the network device cancels the demodulation of the terminal's OCC group data. For other terminals in the OCC group besides the terminal that reported uplink transmission interval information, the network device can continue to demodulate the data of the other terminals.

[0109] In some implementations, the network device determines the time point for resuming the demodulation terminal's data based on the duration of the interval state. For example, if the terminal is in the interval state for p milliseconds, the network device will resume the uplink transmission of the demodulation terminal's data at (t3+p) after canceling the data at time t3. For instance, according to standard protocols, if the terminal enters the UL Tx gap state and continuously stops uplink transmission for 40 milliseconds, the network device will resume the uplink transmission of the demodulation terminal's data at (t3+40) after canceling the data at time t3.

[0110] The method provided in this embodiment notifies the network device of the uplink transmission interval information in advance before the terminal enters the interval state (UL Tx gap). This allows the network device to know when the terminal will enter the interval state based on the uplink transmission interval information. This reduces the risk that the network device may still demodulate the terminal's data when the terminal enters the interval state because the network device is unaware of the time when the terminal enters the interval state. It also helps the network device to stop demodulating the terminal's data when the terminal enters the interval state, thereby avoiding a decrease in the demodulation performance of the network device and a waste of processing resources.

[0111] The above embodiments illustrate the overall process of the terminal notifying uplink transmission interval information. The following examples illustrate the method of carrying uplink transmission interval information.

[0112] In some implementations, a Medium Access Control Element (MAC CE) is defined to carry uplink transmission interval information. For example, in step S230 of the embodiment in Figure 2 above, the terminal fills the MAC CE with the uplink transmission interval information to obtain a MAC CE carrying the uplink transmission interval information. The terminal sends the MAC CE to the network device. In some implementations, during NPUSCH repetition transmission, the terminal sends a MAC CE carrying the uplink transmission interval information on the NPUSCH after a certain continuous uplink transmission time point. Considering that the MAC CE can be transmitted along with service data, using the MAC CE to carry the uplink transmission interval information requires fewer resources to send the uplink transmission interval information, making it more suitable for scenarios where uplink service data is transmitted.

[0113] In some implementations, the MAC CE also includes a Logical Channel Group ID (LCG ID). For example, please refer to Figure 3, which is a schematic diagram of a MAC CE format provided in an embodiment of this application. The MAC CE is 8 bits long and includes an LCG ID field and a UL gap field. The LCG ID field includes 3 bits and contains the LCG ID. The UL gap field includes 5 bits and contains uplink transmission interval information. For example, a UL gap field containing 13 can indicate that the terminal stopped uplink transmission at the 13th millisecond or 13*N milliseconds after sending the MAC CE, where the value of N can be predetermined. Alternatively, a UL gap field containing 20 indicates that the terminal has been continuously uplinking for 20 milliseconds when sending the MAC CE.

[0114] In other implementations, Radio Resource Control (RRC) signaling is used to carry uplink transmission interval information, and the terminal sends RRC signaling carrying uplink transmission interval information to the network device.

[0115] In some implementations, considering that uplink transmission interval information may fail to be transmitted successfully on the first attempt, the terminal improves the transmission success rate by sending the uplink transmission interval information multiple times. For example, the terminal sends uplink transmission interval information 1 to the network device; if the network device receives uplink transmission interval information 1 and, based on it, determines the time point at which the terminal entered the interval state, it sends an acknowledgment message back to the terminal. If no acknowledgment message is received from the network device for uplink transmission interval information 1, the terminal sends uplink transmission interval information 2 to the network device. If an acknowledgment message is received from the network device for uplink transmission interval information 1, the terminal does not need to resend the uplink transmission interval information to the network device.

[0116] In some implementations, when the terminal sends uplink transmission interval information multiple times, the terminal modifies the specific value in the uplink transmission interval information each time it sends the uplink transmission interval information.

[0117] For example, uplink transmission interval information 1 includes the time difference between the time of transmission of uplink transmission interval information 1 and the time when the terminal enters the interval state, and uplink transmission interval information 2 includes the time difference between the time of transmission of uplink transmission interval information 2 and the time when the terminal enters the interval state. As a specific example, when the terminal sends uplink transmission interval information 1, there are 30 milliseconds remaining before entering the interval state; uplink transmission interval information 1 includes 30. After sending uplink transmission interval information 1, 2 milliseconds later, the terminal sends uplink transmission interval information 2, at which point there are 28 milliseconds remaining before entering the interval state; uplink transmission interval information 2 includes 28.

[0118] For example, uplink transmission interval information 1 includes the duration of continuous uplink transmission at the time the uplink transmission interval information 1 was sent, and uplink transmission interval information 2 includes the duration of continuous uplink transmission at the time the uplink transmission interval information 2 was sent. As a specific example, when the terminal sends uplink transmission interval information 1, it has been continuously transmitting uplink for 100 milliseconds, and uplink transmission interval information 1 includes 100. After sending uplink transmission interval information 1, the terminal continues uplink transmission for 2 milliseconds, and then sends uplink transmission interval information 2. At this point, it has been continuously transmitting uplink for 102 milliseconds, and uplink transmission interval information 2 includes 102.

[0119] The method shown in Figure 2 will be illustrated below using the scenario where the terminal is assigned an OCC group for NPUSCH repetition transmission.

[0120] For example, please refer to Figure 4, which is a flowchart of NPUSCH repetition transmission between a terminal and a network device according to an embodiment of this application. In the scenario shown in Figure 4, the terminal is allocated 20 continuous uplink transmissions, and the OCC length is 4. As shown in Figure 4, the terminal determines that it needs to enter an interval state after the 13th uplink transmission, and the duration of each transmission is 1 millisecond. During the 5th to 8th continuous uplink transmissions, the terminal sends uplink service data and MAC CE to the network device on the NPUSCH. The MAC CE includes 13. The network device receives the MAC CE and determines that the terminal will enter the interval state after 13 milliseconds. Then, the terminal enters the interval state during the 13th millisecond of continuous uplink transmission, and the network device stops demodulating the terminal's uplink data at the 13th millisecond. After maintaining the interval state for 40 milliseconds, the terminal resumes continuous uplink transmission.
