[0029] The embodiments of the present disclosure provide a communication method, a communication device, a communication system, and a storage medium.

[0030] In a first aspect, an embodiment of the present disclosure provides a communication method, which is executed by a terminal. The method includes:

[0031] The first layer of the terminal sends a first indication to the second layer of the terminal based on first data; wherein the first layer is used to send data to the second layer, and the second layer is used to count the amount of data to be sent by the terminal, the first data is: data received by the first layer and not yet reached the second layer, the first data is data of a first device, and the first device is: an environmental Internet of Things device; the first indication is used to indicate a first data amount corresponding to the first data;

[0032] The second layer sends a first report to the network device based on the first indication, where the first report is used to indicate the amount of data to be sent by the terminal.

[0033] In the above embodiment, the first layer of the terminal will determine the first data it has received and has not yet reached the second layer, and will indicate the first data volume corresponding to the first data to the second layer of the terminal. In addition, the second layer can determine the amount of data to be sent by the terminal based on the first data volume indicated by the first layer, and further send a first report to the network device based on the amount of data to be sent to request resources. Among them, the first data is the data of the first device, and the first device is an environmental Internet of Things device. It can be seen that the present disclosure provides a method for a terminal to determine the first report for the environmental Internet of Things system, so that when the terminal determines the first report (i.e., when counting the amount of data to be sent), it can take into account the data of the environmental Internet of Things device received by the terminal. When the subsequent network device schedules resources for the terminal based on the first report reported by the terminal, the scheduled resources can also take into account the data of the environmental Internet of Things device to be sent by the terminal, thereby ensuring the successful transmission of the data of the environmental Internet of Things device by the terminal and ensuring the communication stability of the environmental Internet of Things device. Furthermore, in the above embodiment, the first layer of the terminal pre-indicates first data (i.e., data from the ambient IoT device) that has reached the first layer but has not yet reached the second layer to the second layer, so that the second layer can pre-calculate the data that will arrive at the second layer. Thus, when the first report is triggered, the second layer can use the first report to request resources for the data that has not yet reached the second layer but is about to arrive at the second layer. This allows the data to be directly transmitted using the requested resources when it reaches the second layer, without the need to request resources again. This improves communication efficiency, simplifies communication steps, and saves communication resources and costs.

[0034] In conjunction with some embodiments of the first aspect, in some embodiments, the first layer of the terminal sends a first indication to the second layer of the terminal based on the first data, including at least one of the following:

[0035] The first data amount is greater than a first threshold, and the first layer sends the first indication to the second layer;

[0036] The terminal determines that the number of times the first data is received is greater than or equal to a second threshold, and the first layer sends the first indication to the second layer;

[0037] When the timer of the terminal times out, the first layer sends the first indication to the second layer; wherein the timer is started at: when the first layer receives the first data;

[0038] The terminal autonomously determines that the first layer sends the first indication to the second layer.

[0039] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0040] Each time the first layer receives the first data, it starts or restarts the timer.

[0041] In the above embodiment, the specific execution conditions for the first layer to send the first indication to the second layer are defined, so that when the corresponding conditions are met, the first layer can successfully send the first indication to the second layer, so that the second layer can successfully know the first data volume of the first data based on the first indication, so that the second layer can take the first data into consideration when subsequently determining the first report (i.e., when counting the amount of data to be sent), and when the subsequent network device schedules resources for the terminal based on the first report reported by the terminal, the scheduled resources can also take the first data to be sent by the terminal into consideration, thereby ensuring that the terminal can successfully send the first data (i.e., data of the environmental Internet of Things device) based on the resources scheduled by the network device, thereby ensuring the communication stability of the environmental Internet of Things device.

[0042] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0043] The first layer of the terminal updates the first data amount and / or updates the number of times the first data is received based on the data received from the at least one first device.

[0044] In the above embodiment, the first layer of the terminal updates the first data volume and / or the number of times the first data is received in real time based on data received from at least one first device, thereby ensuring the accuracy of the first layer's statistics on the "first data volume and / or the number of times the first data is received." This allows the first layer to accurately determine whether the condition for "sending the first indication" is currently met based on the first data volume and / or the number of times the first data is received, thereby ensuring that the first layer can accurately send the first indication to the second layer at the right time, thereby ensuring communication accuracy. Furthermore, under the premise that the first layer accurately counts the first data volume, it can also ensure that the first layer accurately indicates the first data volume to be sent to the second layer. Subsequently, when the second layer subsequently submits a first report requesting resources to the network device based on the first data volume, it can ensure that the second layer accurately requests resources whose size is adapted to the first data volume. This avoids the situation where "due to inaccurate statistics on the first data volume by the first layer, the network device ultimately schedules fewer resources, resulting in failure to successfully send the first data, or the network device ultimately schedules more resources, resulting in waste of resources." This ensures the successful transmission of the first data and avoids waste of resources.

[0045] In combination with some embodiments of the first aspect, in some embodiments, the first threshold, the second threshold, and the timing duration of the timer are determined based on at least one of network device configuration, pre-configuration, and protocol agreement.

[0046] In the above embodiment, a specific method for determining the first threshold, the second threshold, and the timing duration of the timer is provided, so that the first layer of the terminal can successfully determine the first threshold, the second threshold, and the timing duration of the timer, and then the first layer can determine when to send the first indication to the second layer based on at least one of the first threshold, the second threshold, and the timing duration of the timer, and determine the successful sending of the first indication.

[0047] In conjunction with some embodiments of the first aspect, in some embodiments, the second layer sending a first report to the network device based on the first indication includes:

[0048] The first report is triggered, and the second layer counts the first data amount indicated by the first indication into the amount of data to be sent by the second layer to send the first report.

[0049] In the above embodiment, a method is provided for how the second layer of a terminal sends a first report to a network device based on a first data volume, so that the second layer can successfully send the first report to the network device, and then the network device can schedule resources for sending data to be sent to the terminal based on the first report, thereby ensuring the successful sending of the data to be sent by the terminal and ensuring communication stability.

[0050] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes at least one of the following:

[0051] The first layer sends second data to the second layer, and the first layer sends a second indication to the second layer, wherein the second data is part or all of the first data, and the second indication is used to indicate that an amount of the second data belongs to the first amount of data indicated by the first indication;

[0052] The first layer sends second data to the second layer, and the first layer sends a third indication to the second layer; the third indication is used to indicate a second data amount, and the second data amount is: the data amount obtained by subtracting the data amount corresponding to the second data from the first data amount.

[0053] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes at least one of the following:

[0054] The second layer receives the second data and the second indication, subtracts a data amount corresponding to the second data from a first data amount indicated by the first indication to obtain a third data amount, and when the first report is triggered, the second layer counts the third data amount into a to-be-sent data amount of the second layer to send the first report;

[0055] The second layer receives the second data and the third indication. When the first report is triggered, the second layer adds the second data amount indicated by the third indication to the amount of data to be sent by the second layer to send the first report.

[0056] In the above embodiment, since the first indication is the first data amount corresponding to the first data indicating "has reached the first layer but has not reached the second layer", after the first layer sends the first indication to the second layer, if the first layer sends part or all of the first data to the second layer, wherein, since the part or all of the data has been previously counted by the first layer as data "has reached the first layer but has not reached the second layer", at the same time, after the part or all of the data reaches the second layer, the second layer will also count the part or all of the data as data to be sent, thereby causing repeated statistics of the part or all of the data, resulting in the amount of data to be sent counted by the second layer being greater than the actual amount of data to be sent, resulting in inaccurate statistics. Therefore, in order to avoid this situation, after the first layer sends the first indication to the second layer, if part or all of the first data is also sent to the second layer, the first layer needs to instruct the second layer to update the statistics. For example, the first layer can send the above-mentioned second indication and / or third indication to the second layer, so that the second layer can know, based on the second indication and / or third indication, that the data sent by the first layer to the second layer is already counted data, thereby avoiding repeated statistics of the data and ensuring the accuracy of the second layer's data volume statistics. When the second layer subsequently reports the first report requesting resources to the network device based on its counted data volume, it can ensure that the second layer can accurately request resources whose resource size is adapted to the amount of data to be sent, avoiding the situation where "the amount of data to be sent counted by the second layer is greater than the actual amount of data to be sent, resulting in more resources being scheduled by the network device and causing resource waste", thereby ensuring the successful transmission of data and avoiding resource waste.

[0057] In conjunction with some embodiments of the first aspect, in some embodiments, at least one of the following is included:

As shown in Figure 1A, the communication system 100 may include a first device, a terminal, and a network device. Optionally, the first device may be an IoT device, and the terminal may serve as an intermediate node for communication between the first device and the network device, for enabling communication between the first device and the network device.

[0129] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0130] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0132] Optionally, in order to realize battery-free IoT communication, a new low-power ambient Internet of Things (A-IoT) device is introduced, wherein the A-IoT device may also be referred to as: ambient Internet of Things user equipment (A-IoT UE), A-IoT terminal, A-IoTTag, low-power device, ambient Internet of Things device, passive Internet of Things device, etc., which is not limited in the present disclosure. Optionally, the newly introduced A-IoT device does not need to be configured with a battery or replace the battery, nor does it need to generate energy by itself. It can collect energy from the outside, such as collecting energy based on the surrounding environment or signals sent by surrounding devices, and can communicate based on the collected energy.

[0133] Optionally, the above-mentioned A-IoT device can communicate with the terminal and / or network device based on the energy collected from the outside world. Specifically, in some embodiments, the terminal and / or network device can send a signal to the A-IoT device. After receiving the signal, the A-IoT device can send corresponding response information to the terminal and / or network device or perform corresponding operations. Among them, when the A-IoT device sends response information to the terminal and / or network device, it can be sent in a backscatter working mode or in an active sending working mode. Optionally, the above-mentioned "backscatter working mode" can be, for example: the terminal and / or network device sends an electromagnetic wave (continuous wave, CW) signal to the A-IoT device, and the A-IoT device adjusts the matching between the receiving antenna and the impedance according to the information to be sent, enhances the reflection of the incident CW signal, and modulates the perception data obtained by itself onto the reflected signal to complete the transmission of the data, thereby realizing backscatter communication. Optionally, the above-mentioned "active transmission working mode" can be understood as, for example: actively generating signals and actively sending signals without CW signal excitation, wherein the A-IoT device can actively generate signals and actively send signals based on its stored energy, and the energy stored in the A-IoT device can be the energy that the terminal and / or network device pre-charges the A-IoT device.

[0134] Optionally, the aforementioned A-IoT devices may include multiple different types of devices, such as first type A-IoT devices and second type A-IoT devices, wherein different types of A-IoT devices have different corresponding capabilities.

[0135] Optionally, the above-mentioned first type A-IoT device has energy storage capability, but does not have independent signal generation and / or amplification capability, and its uplink transmission relies on backscatter transmission; that is, the first type A-IoT device needs to use the backscatter working mode to send signals to the terminal and / or network device (such as the aforementioned response information), which has the lowest complexity and cost and very low power consumption.

[0136] Optionally, the above-mentioned second type A-IoT device has energy storage capability and independent signal amplification capability, and its uplink transmission can be based on internally generated signals, or its uplink transmission can rely on backscatter transmission; that is, the second type A-IoT device can actively send signals to the terminal and / or network device based on the internally generated signal, or the second type A-IoT device can use the backscatter working mode to send signals to the terminal and / or network device.

[0137] Alternatively, the device types of the aforementioned A-IoT devices can be "backscatter" and "non-backscatter," where "backscatter" can, for example, refer to sending signals based on backscattering, and "non-backscatter" can, for example, refer to actively sending signals. It should be noted that the aforementioned device types are merely examples, and other naming formats for device types may exist, which are not specifically limited in this disclosure.

[0138] Optionally, in an IoT system, there are three types of data transmission by A-IoT devices:

[0139] Example 1: An A-IoT device reports data based on demand from network devices, such as inventory counts.

[0140] Example 2: Triggering an A-IoT device to report based on environmental IoT. For example, when the A-IoT device detects that the temperature of a sensor is higher than the configured threshold, the A-IoT device reports the relevant data.

[0141] Example 3: Periodic data reporting. For example, network devices can periodically request data from A-IoT devices to implement periodic environmental IoT data reporting; or they can trigger A-IoT devices to implement periodic environmental IoT data reporting.

[0142] Optionally, the above-mentioned A-IoT device can be applied to a variety of different communication architectures in the communication system, wherein Figures 1B-1F are schematic diagrams of the communication architecture of the A-IoT device according to an embodiment of the present disclosure. Optionally, as shown in Figure 1B, the A-IoT device (i.e., the Ambient IoT device in Figure 1B) and the network device (such as the base station (BS)) can directly receive and send data.

[0143] Optionally, as shown in Figure 1C, the A-IoT device and the network device (such as a base station (BS)) can indirectly receive and send data through an intermediate node, where the intermediate node can be, for example, a relay, an integrated access backhaul (IAB) device, a terminal, or a repeater. Optionally, the network device and the intermediate node can communicate through a user to network interface universal (Uu) link.

[0144] Optionally, as shown in FIG1D , uplink data can be directly transmitted between the A-IoT device and the network device (such as a base station (BS)), and downlink data can be indirectly transmitted between the A-IoT device and the network device (such as a base station (BS)) through an intermediate node. The intermediate node can be, for example, a relay, an IAB device, a terminal, or a repeater. Optionally, the network device and the intermediate node can communicate via a Uu link.

[0145] Optionally, as shown in Figure 1E, downlink data can be transmitted directly between the A-IoT device and the network device (such as a base station (BS)), and uplink data can be transmitted indirectly between the A-IoT device and the network device (such as a base station (BS)) through an intermediate node. Optionally, the network device and the intermediate node can communicate via a Uu link.

[0146] Optionally, as shown in FIG1F , data can be directly received and sent between the A-IoT device and the terminal (or user equipment (UE)). The terminal can be responsible for collecting data from the A-IoT device and forwarding the collected data to the network device.

[0147] Optionally, for the communication architecture shown in Figures 1C and 1E above, when the terminal acts as an intermediate node, it usually needs to receive data from the A-IoT device and forward the data to the network device. Among them, for the terminal, when it has data to be sent to the network device, the terminal usually needs to send a buffer status report (Buffer Status Report, BSR) to the network device to inform the terminal of the amount of data to be sent, so that the network device can schedule resources for carrying the data to be sent for the terminal based on the BSR. However, at present, for the communication architecture shown in Figures 1C and 1E above, there is no method for how the terminal calculates the BSR. Therefore, there is an urgent need for a BSR determination method for the terminal to calculate the BSR of the terminal for the communication architecture shown in Figures 1C and 1E.

[0148] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0149] Step 2101: At least one first device sends data.

[0150] Optionally, the first device may be an environmental Internet of Things device. In some embodiments, the first device may be an A-IoT device described before the embodiment of FIG. 2 . For relevant introductions to the A-IoT device, please refer to the description before the embodiment of FIG. 2 .

[0151] In some embodiments, at least one first device may send data on a resource or channel (e.g., a designated resource or channel). The resource or channel may be configured or preconfigured. In some embodiments, the resource or channel may be specified by a protocol. In some embodiments, the resource or channel may be dynamically indicated, for example, via an instruction, command, or signaling. Furthermore, this disclosure does not specifically limit how the at least one first device obtains the resource or channel.

[0152] Optionally, in some embodiments, when at least one first device sends data on a resource or channel, the terminal may receive the data sent by the first device on the resource or channel. The terminal may be an intermediate node for communication between the first device and the network device, and the terminal may be used to forward the data of the first device. For example, the terminal may be an intermediate node in FIG. 1C or 1E above, wherein a detailed introduction to the intermediate node may refer to the description before the embodiment of FIG. 2 . Also, optionally, the terminal in the embodiment of the present disclosure may refer to a terminal in a Radio Resource Control Connected (RRC_Connected) state.

[0153] Step 2102: The first layer of the terminal sends a first indication to the second layer of the terminal based on the first data.

[0154] Optionally, the first layer may be used to send data to the second layer, and the second layer may be used to count the amount of data to be sent by the terminal. For example, in some embodiments, the first layer may be, for example, the Radio Resource Control (RRC) layer of the terminal, and the second layer may be, for example, the Packet Data Convergence Control (PDCP) layer. Furthermore, the first data may be data received by the first layer and not yet reached the second layer, and the first data may be data of the first device.

[0155] Specifically, in some embodiments, when the RRC layer of the terminal receives data, it is usually necessary to first encapsulate the data into RRC signaling, and then submit the RRC signaling to the PDCP layer so that it can be submitted layer by layer until it is sent to the network device. Based on this, in some embodiments, the above-mentioned first data can be, for example, a service data unit (SDU) corresponding to data that has reached the RRC layer but has not yet reached the PDCP layer. The first data can also be called, for example, a virtual SDU, an estimated SDU, a potential SDU, or other names, which are not specifically limited in this disclosure.

[0156] Optionally, the first indication may be used to indicate a first data amount corresponding to the first data. For example, the first data amount may be the size of an SDU corresponding to the first data. The first data amount may also be referred to as a virtual SDU size, an estimated SDU size, a potential SDU size, or other names, which are not specifically limited in this disclosure. In some embodiments, the first data amount may be calculated in bytes.

[0157] In some embodiments, the first layer of the terminal may send the first indication to the second layer based on at least one of the following methods.

[0158] Method 1: When the first data amount is greater than a first threshold, the first layer sends a first indication to the second layer.

[0159] Optionally, in some embodiments, because one or more first devices send data to the terminal, the first layer of the terminal needs to count the first data volume in real time. For example, the first layer of the terminal may update the first data volume based on the data received from the one or more first devices. For example, assuming that each time the first layer of the terminal receives data from the first device, it may determine that the current first data volume = the first data volume counted last time + the size of the data received from the first device this time.

[0160] And, optionally, when the first layer determines that the first data volume is greater than the first threshold, it means that the first layer currently caches a large amount of first data. At this time, the first layer can send a first indication to the second layer to indicate the first data volume, so that the second layer can subsequently request resources for sending the first data from the network device based on the first data volume.

[0161] In some embodiments, the first threshold value may be determined by the terminal based on at least one of network device configuration, pre-configuration, protocol agreement, and terminal implementation. The first threshold value may be, for example, called TagDataThreshold, TagDataByte, or other names, which are not specifically limited in this disclosure. When the first threshold value is TagDataByte, it can also be understood that the TagDataByte indicates that the first threshold value is in bytes.

[0162] Method 2: When the terminal determines that the number of times the first data is received is greater than or equal to the second threshold, the first layer sends a first indication to the second layer.

[0163] Optionally, in some embodiments, because one or more first devices send data to the terminal, the first layer of the terminal needs to count the number of times the first data is received in real time. For example, the first layer of the terminal may update the number of times the first data is received based on the data received from the one or more first devices. For example, assuming that each time the first layer of the terminal receives data from the first device, it may determine that the current number of times the first data is received = the last counted number of times the first data is received + 1.

[0164] And, optionally, when the first layer determines that the number of times the first data is received is greater than or equal to the second threshold, it means that the first layer currently caches the first data of a large amount of devices. At this time, the first layer can send a first indication to the second layer to indicate the amount of the first data, so that the second layer can subsequently request resources for sending the first data from the network device based on the first data amount.

[0165] In some embodiments, the second threshold may be determined by the terminal based on at least one of network device configuration, pre-configuration, protocol agreement, and terminal implementation. The second threshold may be called TagNumberThreshold, or may be named otherwise, which is not specifically limited in this disclosure.

[0166] Method three: When the timer of the terminal times out, the first layer sends a first indication to the second layer.

[0167] Optionally, the timer may be started when the first layer receives the first data; and each time the first layer receives the first data, the first layer starts or restarts the timer. In some embodiments, the timer duration may be determined by the terminal based on at least one of network device configuration, pre-configuration, protocol agreement, and terminal implementation.

[0168] And, optionally, when the timer times out, it means that a long time has passed since the first layer started to receive the first data. At this time, it means that the first layer may have cached a large amount of first data. The first layer can send a first indication to the second layer to indicate the amount of the first data, so that the second layer can subsequently request resources for sending the first data from the network device based on the amount of the first data.

[0169] Method 4: The terminal autonomously determines that the first layer sends a first instruction to the second layer.

[0170] Optionally, in some embodiments, the terminal may determine that the first layer sends the first indication to the second layer based on implementation.

[0171] In the above embodiment, the first layer of the terminal updates the first data volume and / or the number of times the first data is received in real time based on data received from at least one first device, thereby ensuring the accuracy of the first layer's statistics on the "first data volume and / or the number of times the first data is received." This allows the first layer to accurately determine whether the condition for "sending the first indication" is currently met based on the first data volume and / or the number of times the first data is received, thereby ensuring that the first layer can accurately send the first indication to the second layer at the right time, thereby ensuring communication accuracy. Furthermore, under the premise that the first layer accurately counts the first data volume, it can also ensure that the first layer accurately indicates the first data volume to be sent to the second layer. Subsequently, when the second layer subsequently submits a first report requesting resources to the network device based on the first data volume, it can ensure that the second layer accurately requests resources whose size is adapted to the first data volume. This avoids the situation where "due to inaccurate statistics on the first data volume by the first layer, the network device ultimately schedules fewer resources, resulting in failure to successfully send the first data, or the network device ultimately schedules more resources, resulting in waste of resources." This ensures the successful transmission of the first data and avoids waste of resources.

[0172] Step 2103: The second layer sends a first report to the network device based on the first indication.

[0173] Optionally, the first report may be used to indicate the amount of data to be sent by the terminal. For example, the first report may include the amount of data to be sent by the terminal. Furthermore, the first report may be used to request the network device to schedule resources for the terminal based on the first report. The resources may be used by the terminal to send the data to be sent. Optionally, the first report may be, for example, a BSR.

[0174] Optionally, in some embodiments, when the first report is triggered, the second layer may count the first data amount indicated by the first indication into the amount of data to be sent of the second layer to send the first report. The above-mentioned "first report is triggered" can be understood as: the first report needs to be generated and / or sent. For example, when the terminal needs to send data to the network device but there are no available resources, the first report is triggered to request resources. In addition, the above-mentioned "amount of data to be sent on the second layer" can be the same concept as the aforementioned "amount of data to be sent by the terminal", or the "amount of data to be sent on the second layer" can be a subset of the aforementioned "amount of data to be sent by the terminal".

[0175] And, for example, in some embodiments, when the second layer is a PDCP layer, the PDCP layer may count the amount of data to be sent at the PDCP layer based on the following procedure:

[0176] For the purpose of media access control (MAC) buffer status reporting, the transmitting PDCP entity may regard the following as the amount of data to be sent at the PDCP layer:

[0177] - potential PDCP SDUs from the RRC layer;

[0178] - PDCP SDUs without constructing PDCP data PDUs;

[0179] -PDCP data PDUs that have not yet been submitted to lower layers

[0180] -the PDCP Control PDUs;

[0181] - for AM DRBs, retransmitted PDCP SDUs according to clauses 5.1.2 and 5.13;

[0182] - For AM DRBs, retransmit the PDCP data PDU according to clause 5.5.

[0183] Optionally, the aforementioned “potential PDCP SDU from the RRC layer” is the aforementioned first data amount.

[0184] For example, assuming that the first data amount indicated by the first indication sent by the first layer of the terminal in the above step 2102 is 30 bytes, when the first report is triggered, the second layer can count the first data amount 30 bytes into the amount of data to be sent by the second layer to send the first report.

[0185] Step 2104: The first layer sends second data to the second layer.

[0186] Optionally, the second data may be part or all of the aforementioned first data.

[0187] Step 2105: The first layer sends a second indication and / or a third indication to the second layer.

[0188] Optionally, the second indication may be used to indicate that the data volume of the second data belongs to the first data volume indicated by the first indication.

[0189] Optionally, the third indication can be used to indicate a second data amount, which can be: the data amount obtained by subtracting the data amount corresponding to the second data from the first data amount. In other words, the second data amount is "data received but not yet reached the first device of the second layer" after the first layer submits the second data to the second layer. It is understandable that the second data amount is defined the same as the first data amount, except that it is an update of the first data amount after the first layer submits the second data to the second layer, and is used to indicate the data amount of "data received but not yet reached the first device of the second layer" after the first layer submits the second data to the second layer.

[0190] For example, assuming that the first data amount determined by the terminal in the above step 2102 is 30 bytes, and that the first layer sends 10 bytes of second data in the 30 bytes of first data to the second layer in the above step 2104, the first layer can send a second indication to the second layer, and the second indication can be used to indicate that the 10 bytes of second data belong to the first data amount of 30 bytes, or the first layer can send a third indication to the second layer, and the third indication can indicate the second data amount, and the second data amount can be: (30-10)=20 bytes. The second data amount is actually: after the first layer sends the second data to the second layer, the data amount corresponding to the "data received by the first device but not yet reached the second layer" of the first layer.

[0191] Step 2106: The second layer sends a first report to the network device based on the second indication and / or the third indication.

[0192] Optionally, in some embodiments, when the second layer receives the second indication, the second layer may subtract the data amount corresponding to the second data from the first data amount indicated by the first indication to obtain a third data amount, and when the first report is triggered, the second layer may count the third data amount into the data amount to be sent of the second layer to send the first report.

[0193] For example, assume that the first data amount determined by the terminal in step 2102 is 30 bytes, and that in step 2104, the first layer sends 10 bytes of second data from the 30 bytes of first data to the second layer, and that the first layer sends a second indication to the second layer, indicating that the 10 bytes of second data belong to the first data amount of 30 bytes. In this case, the second layer can subtract the data amount corresponding to the second data from the first data amount of 30 bytes to obtain a third data amount of 20 bytes. This third data amount of 20 bytes is essentially the data amount corresponding to the "data received by the first layer but not yet reaching the first device on the second layer" after the first layer sends the second data to the second layer. In this case, when the first report is triggered, the second layer can count the third data amount of 20 bytes into the data amount to be sent by the second layer in order to send the first report.

[0194] Optionally, in some other embodiments, when the second layer receives the third indication, if the first report is triggered, the second layer may count the second data amount indicated by the third indication into the amount of data to be sent by the second layer to send the first report. For an introduction to the first report, please refer to the above description.

[0195] For example, assuming that the first data amount determined by the terminal in step 2102 is 30 bytes, and that in step 2104, the first layer sends 10 bytes of second data from the 30 bytes of first data to the second layer, and that the first layer sends a third indication to the second layer indicating that the second data amount is 20 bytes, then after the first layer sends the second data to the second layer, the data amount corresponding to "data received by the first layer but not yet reaching the first device in the second layer" is 20 bytes. Therefore, when the first report is triggered, the second layer can count the 20 bytes of second data as part of the amount of data to be sent by the second layer in order to send the first report.

[0196] It can be seen from the above steps 2104-2106 that since the first indication is the first data amount corresponding to the first data indicating "has reached the first layer but has not reached the second layer", therefore, after the first layer sends the first indication to the second layer, if the first layer sends part or all of the first data to the second layer, wherein, since the part or all of the data has been previously counted by the first layer as data "has reached the first layer but has not reached the second layer", at the same time, after the part or all of the data reaches the second layer, the second layer will also count the part or all of the data as data to be sent, which will cause repeated statistics of the part or all of the data, resulting in the amount of data to be sent counted by the second layer being greater than the actual amount of data to be sent, resulting in inaccurate statistics. Therefore, in order to avoid this situation, after the first layer sends the first indication to the second layer, if part or all of the first data is also sent to the second layer, the first layer needs to instruct the second layer to update the statistics. For example, the first layer can send the above-mentioned second indication and / or third indication to the second layer, so that the second layer can know, based on the second indication and / or third indication, that the data sent by the first layer to the second layer is already counted data, thereby avoiding repeated statistics of the data and ensuring the accuracy of the second layer's data volume statistics. When the second layer subsequently reports the first report requesting resources to the network device based on its counted data volume, it can ensure that the second layer can accurately request resources whose resource size is adapted to the amount of data to be sent, avoiding the situation where "the amount of data to be sent counted by the second layer is greater than the actual amount of data to be sent, resulting in more resources being scheduled by the network device and causing resource waste", thereby ensuring the successful transmission of data and avoiding resource waste.

[0197] Step 2107: The network device schedules resources for the terminal based on the first report.

[0198] Optionally, the network device may schedule resources for the terminal to send the data to be sent based on the amount of data to be sent indicated in the first report. Optionally, the terminal may receive the resources scheduled by the network device for the terminal.

[0199] Step 2108: The terminal sends data based on the resources scheduled by the network device.

[0200] Alternatively, the second layer of the terminal may send data based on resources scheduled by the network device, or other layers of the terminal may send data based on resources scheduled by the network device. Alternatively, the terminal may send data to the network device, and the network device may receive data sent by the terminal based on the scheduled resources.

[0201] In the above embodiment, the first layer of the terminal will determine the first data it has received and has not yet reached the second layer, and will indicate the first data volume corresponding to the first data to the second layer of the terminal. In addition, the second layer can determine the amount of data to be sent by the terminal based on the first data volume indicated by the first layer, and further send a first report to the network device based on the amount of data to be sent to request resources. Among them, the first data is the data of the first device, and the first device is an environmental Internet of Things device. It can be seen that the present disclosure provides a method for a terminal to determine the first report for the environmental Internet of Things system, so that when the terminal determines the first report (i.e., when counting the amount of data to be sent), it can take into account the data of the environmental Internet of Things device received by the terminal. When the subsequent network device schedules resources for the terminal based on the first report reported by the terminal, the scheduled resources can also take into account the data of the environmental Internet of Things device to be sent by the terminal, thereby ensuring the successful transmission of the data of the environmental Internet of Things device by the terminal and ensuring the communication stability of the environmental Internet of Things device. Furthermore, in the above embodiment, the first layer of the terminal pre-indicates first data (i.e., data from the ambient IoT device) that has reached the first layer but has not yet reached the second layer to the second layer, so that the second layer can pre-calculate the data that will arrive at the second layer. Thus, when the first report is triggered, the second layer can use the first report to request resources for the data that has not yet reached the second layer but is about to arrive at the second layer. This allows the data to be directly transmitted using the requested resources when it reaches the second layer, without the need to request resources again. This improves communication efficiency, simplifies communication steps, and saves communication resources and costs.

For example, step 2101 may be implemented as an independent embodiment, step 2102 may be implemented as an independent embodiment, step 2103 may be implemented as an independent embodiment, and step 2101+step 2102 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0262] In some embodiments, the above method may include the method described in the above embodiments of the communication system side, the first device side, the terminal side, the network device side, etc., which will not be repeated here.

[0263] The communication method involved in the embodiment of the present disclosure may include at least one of steps 5101 to 5105. For example, step 5101 may be implemented as an independent embodiment, and step 5102 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0264] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0265] The following is an exemplary introduction to the above method.

[0266] The present disclosure proposes a BSR calculation method in an A-IOT scenario, which solves the problem of how the data of A-IOT devices affects the BSR calculation of intermediate nodes under the A-IOT topology 2 architecture (i.e., the communication architecture shown in Figure 1C above).

[0267] Optional Example 1: The RRC layer (ie, the aforementioned first layer) of the UE (ie, the aforementioned terminal) instructs the PDCP layer (ie, the aforementioned second layer) of the "estimated SDU" size.

[0268] Example: When an RRC_CONNECTED UE receives a tag (or ambient IoT device), the tag data size variable TagData = TagData + tag data size. If TagData > TagDataByte, the UE's RRC layer indicates the PDCP virtual SDU size based on the tag data size. TagDataByte is a threshold configured by the network, pre-configured, specified by the protocol, or determined by the UE implementation. The data volume can be calculated in bytes. The virtual SDU is also called an estimated SDU, but the specific name is not limited.

[0269] Example: When an RRC_CONNECTED UE receives a tag (or ambient IoT device), the tag number variable TagNumber = TagNumber + 1. If TagNumber >= TagNumberThreshold, the UE's RRC layer indicates the PDCP virtual SDU size based on the size of the received tag data. TagNumberThreshold is a threshold configured or pre-configured by the network, specified by the protocol, or determined by the UE implementation.

[0270] Example: When an RRC_CONNECTED UE receives data reported by the first tag, it starts timer T1. If the timer expires, the UE's RRC layer indicates the PDCP virtual SDU size based on the tag data size. The timer size is configured or pre-configured by the network, specified by the protocol, or determined by the UE implementation. Optionally, the UE starts or restarts timer T1 each time it receives data from a tag. If timer T1 expires, the UE's RRC layer indicates the PDCP virtual SDU size based on the tag data size.

[0271] Embodiment: The UE determines based on implementation that the RRC layer indicates the PDCP virtual SDU size according to the Tag data size.

[0272] Example: The RRC layer of the UE delivers a PDCP SDU to the PDCP layer and updates the estimated SDU size. For example, if the tag data is encapsulated at the RRC layer and delivered to the PDCP layer, the RRC layer needs to update the estimated SDU size, which indicates the size of a potential PDCP SDU that has not yet been delivered.

[0273] Optional Example 2: The PDCP of the UE counts the estimated SDU size into the amount of data to be sent.

[0274] Example: When the BSR triggers the need to count the data to be sent by the PDCP, the PDCP counts the estimated SDU indicated by the RRC layer into the data to be sent.

[0275] Example: The specific protocol changes are as follows:

[0276] For the purpose of MAC buffer status reporting, the transmitting PDCP entity shall consider the following as PDCP data volume:

[0277] -the potential PDCP SDUs from RRC layer;

[0278] -the PDCP SDUs for which no PDCP Data PDUs have been constructed;

[0279] -the PDCP Data PDUs that have not been submitted to lower layers;

[0280] -the PDCP Control PDUs;

[0281] -for AM DRBs, the PDCP SDUs to be retransmitted according to clause 5.1.2 and clause 5.13;

[0282] -for AM DRBs, the PDCP Data PDUs to be retransmitted according to clause 5.5.
