[0152] Figure 1A is a schematic diagram illustrating the architecture of a communication system according to an embodiment of the present disclosure. As shown in Figure 1A, the communication system 100 may include a terminal and a network device. Optionally, the network device may include at least one of an access network device and a core network device.

[0153] In some embodiments, the terminal includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0154] In some embodiments, the access network device is, for example, a node or device that accesses a terminal to a wireless network.

[0155] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0156] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0158] 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.

[0159] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0160] 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).

[0161] Optionally, the device mentioned in the foregoing that collects energy and communicates based on the collected energy can be called an Ambient Internet of Things (A-IoT) device (or a low-power device). Optionally, the 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 downlink signal to the A-IoT device. After the A-IoT device receives the downlink signal, it can send a corresponding response message to the terminal and / or network device or perform a corresponding operation. When the A-IoT device sends a response message to the terminal and / or network device, it can use a backscatter working mode to send the response message or it can use an active sending working mode to send the response message. Optionally, the above-mentioned "backscatter working mode" can be, for example, as follows: the terminal and / or network device sends a continuous wave (CW) signal to the A-IoT device, and the A-IoT device obtains energy after receiving the CW signal (such as obtaining energy to activate the receiving and processing module inside the A-IoT device). Afterwards, the internal circuit of the A-IoT device can modulate the information to be sent based on the incident electromagnetic wave (i.e., the CW signal) through load impedance modulation and other methods, and then backscatter the modulated electromagnetic wave carrying the information to the terminal and / or network device, thereby realizing backscatter communications. The modulation mode of the A-IoT device during backscatter communications may include multiple types, for example, amplitude shift keying (ASK), frequency shift keying (FSK), phase shift keying (PSK), etc. Optionally, the aforementioned "active transmission working mode" can be understood, for example, as actively generating and transmitting signals without the need for CW signal excitation, wherein the A-IoT device can actively generate and transmit signals based on its stored energy, and the energy stored in the A-IoT device can be energy pre-charged for the A-IoT device by the terminal and / or network device. As can be seen from the above, the "backscattering working mode" requires the real-time transmission of CW signals to the A-IoT device, while the "active transmission working mode" does not require the real-time transmission of CW signals to the A-IoT device, and only requires the A-IoT device to be pre-charged.

[0162] Optionally, the above-mentioned A-IoT devices may be of different types, for example, including A-IoT device A, A-IoT device B, and A-IoT device C. Different types of A-IoT devices may have different corresponding capabilities.

[0163] Optionally, the above-mentioned A-IoT device A has no energy storage capability, does not support energy storage, and cannot perform independent signal generation or amplification, but needs to use a backscattering working mode to send an uplink signal (such as the aforementioned response information) to the terminal and / or network device, which has the lowest complexity and cost and consumes very little power. In addition, for the A-IoT device A, the energy for monitoring the downlink signal also needs to be provided by an external signal. Optionally, when the terminal and / or network device sends a downlink signal to the A-IoT device A, the downlink signal power received by the A-IoT device A needs to meet a certain power threshold (or called an "activation power threshold") to activate the A-IoT device A and provide the A-IoT device A with sufficient energy to detect the downlink signal.

[0164] Optionally, the above-mentioned A-IoT device B has energy storage capability but cannot generate independent signals. It can communicate using a backscattering working mode and can use the stored energy to amplify the reflected signal.

[0165] Optionally, the A-IoT device C has energy storage capabilities and can independently generate and transmit signals. For example, the A-IoT device C can include a radio frequency (RF) module for active signal transmission. Alternatively, the A-IoT device C can use stored energy to independently generate and transmit signals to achieve active transmission. However, the complexity and cost of the A-IoT device C are relatively high, and the power consumption is relatively high.

[0166] 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 architecture when the A-IoT device communicates with network devices and / or terminals according to embodiments of the present disclosure. Optionally, as shown in Figure 1B, data can be directly received and sent between the A-IoT device and the network device (such as a base station (BS)).

[0167] Optionally, as shown in FIG1C , data can be received and sent indirectly between the A-IoT device and the network device (such as a base station (BS)) 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.

[0168] 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 assisting node, which can be, for example, a relay, an IAB device, a terminal, or a repeater.

[0169] Optionally, as shown in FIG1E , downlink data can be directly transmitted between the A-IoT device and the network device (such as a base station (BS)), and uplink data can be indirectly transmitted between the A-IoT device and the network device (such as a base station (BS)) through an assisting node.

[0170] 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.

[0171] Optionally, for the communication architecture shown in Figures 1C and 1E above, when the terminal acts as an intermediate node or auxiliary 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 (BSR) to the network device to inform the terminal of the amount of data to be sent to the network device, so that the network device can schedule resources for the terminal to carry the data to be sent based on the BSR. However, the current BSR sending mechanism is usually triggered by the amount of data to be sent determined by the high-level layer of the terminal (for example, the amount of data to be sent generated by the terminal itself that needs to be sent to the network device). For the scenario in which the terminal in the communication architecture shown in Figures 1C and 1E needs to forward the data sent by the A-IoT device to the network device, the current BSR mechanism is not applicable. Therefore, there is an urgent need for a BSR sending method for the terminal in the communication architecture shown in Figures 1C and 1E to send BSR.

[0172] FIG2A is a flow chart of a sending method according to an embodiment of the present disclosure. As shown in FIG2A , the present disclosure embodiment relates to a sending method for use in a communication system 100, the method comprising:

[0173] Step 2101: The terminal determines a first data volume.

[0174] Optionally, the first data volume can be the data volume of the first data, and the first data can be, for example, data to be forwarded by the first device through the terminal. Optionally, the first device can be: a device that communicates based on energy collected from the outside world, and the first device can be, for example, the A-IoT device described before the embodiment of Figure 2A, wherein, when the first device is an A-IoT device, the first data can be the data of the first device that the terminal in Figures 1C and 1E needs to forward to the network device. For the relevant introduction to the A-IoT device, Figures 1C and 1E, please refer to the description before the embodiment of Figure 2A.

[0175] Optionally, the first data may be data that the first device has sent to the terminal and needs to be forwarded by the terminal to the network device, or the first data may be data that the first device is about to send to the terminal and needs to be forwarded by the terminal to the network device.

[0176] Optionally, when the first data is data sent by the first device to the terminal, the terminal may determine the actual data volume of the first data received from the first device as the first data volume.

[0177] Optionally, when the first data is data to be sent by the first device to the terminal, the first data amount may be determined based on first information sent by the first device. The first information is used to indicate the data amount of the data to be sent by the first device to the terminal. Optionally, the first device may send the first information to the terminal, and the terminal may determine the data amount indicated by the first information as the above-mentioned first data amount. Optionally, considering the communication overhead when the first device sends the first data amount to the terminal, the first device may quantize the first data amount and send the quantized first data amount to the terminal. Optionally, assuming that the above-mentioned first data amount is within the range of 1000 bits, the first device may quantize the 1000 bits to 0. In this case, the first information sent by the first device may be 0, and the first information is used to indicate that the first data amount is within the range of 1000 bits; or, assuming that the above-mentioned first data amount is within the range of 2000 bits, the first device may quantize the 2000 bits to 2. In this case, the first information sent by the first device may be 2, and the first information is used to indicate that the first data amount is within the range of 2000 bits.

[0178] Optionally, in some other embodiments, the first data amount may be determined by the terminal based on the terminal's ability to transmit the first signal and / or the first signal already transmitted by the terminal. Specifically, in some embodiments, since the first device may not have the ability to transmit data independently, the terminal usually needs to transmit a first signal (e.g., a CW signal) to the first device, which may be used to stimulate the first device to transmit the first data based on a backscattering working mode. For a detailed introduction to the "backscattering working mode," please refer to the previous description of the embodiment of FIG2A. Furthermore, when the first device sends the first data based on the backscattering working mode, the amount of first data that the first device can send is related to the excitation energy of the first signal, and the excitation energy of the first signal is related to the terminal's transmission capability for the first signal. When the terminal has a higher transmission capability for the first signal (for example, the terminal has more resources that can be allocated to the first signal), the excitation energy of the first signal is higher. In this case, the first device can backscatter more first data based on the first signal. When the terminal has a lower transmission capability for the first signal (for example, the terminal has fewer resources that can be allocated to the first signal), the excitation energy of the first signal is lower. In this case, the first device can backscatter less first data based on the first signal. Based on this, in some embodiments, the terminal can determine the amount of first data based on the terminal's transmission capability for the first signal and / or the first signal already sent by the terminal (such as the excitation energy of the first signal already sent).

[0179] It should be noted that in some embodiments, when a terminal is sending a first signal, if the terminal is also performing other transmissions, or if other transmissions have a higher priority, the terminal's ability to transmit the first signal will be relatively weak. In this case, the excitation energy of the first signal transmitted by the terminal will be relatively low, which will cause the amount of data that the first device can backscatter to the terminal to be less than the actual amount of data that the first device needs to send to the terminal. In this case, the first data amount determined by the terminal based on the transmission capability of the first signal will also be less than the actual amount of data that the first device needs to send to the terminal. For example, assuming that the actual amount of data that the first device needs to send to the terminal is M bits, but the terminal currently needs to prioritize other transmissions, which makes the terminal's ability to transmit the first signal relatively weak, resulting in the first signal actually transmitted by the terminal only supporting a portion of the data backscattered by the first device (e.g., M / 2 bits). In this case, the first data amount determined by the terminal based on its transmission capability for the first signal should be M / 2 bits, not M bits.

[0180] Optionally, in some embodiments, the first channel can be used for communication between the terminal and at least one first device, wherein the terminal can determine the first data volume for each first channel, that is, the terminal determines the data volume of the terminal to be forwarded corresponding to each first channel.

[0181] Optionally, in some embodiments, the first channel may be a logical channel or a physical channel. When the first channel is a physical channel, the terminal may also determine the first data volume corresponding to the first channel based on the bandwidth, number, or identifier of the first channel, wherein different bandwidths, different numbers, or different identifiers of the first channel correspond to different first data volumes, and the correspondence between the bandwidth, number, or identifier and the first data volume may be predefined based on the protocol. For example, assuming that the bandwidth of the first channel is AMHz, the first data volume corresponding to the first channel is f(A) bits, where f may be predefined; for another example, assuming that the number or identifier of the first channel is B, the first data volume corresponding to the first channel is f(B) bits, where f may be predefined.

[0182] Based on the above content, it should be noted that when the first channel is a physical channel and the terminal "determines the first data volume corresponding to the first channel based on the bandwidth, number or identifier of the first channel", then for the first device, when the first device sends the first data, it can be based on the first data volume of the first data to determine the first channel for sending the first data, so that when the terminal determines the first data volume corresponding to the first channel based on the bandwidth, number or identifier of the first channel, it can accurately determine the correct first data volume.

[0183] Step 2102: The terminal sends a first report to the network device based on the first data volume.

[0184] Optionally, the first report may be used to indicate a first data volume, for example, the first report may include the first data volume. Furthermore, the first report may be used to request the network device to schedule resources for the first data based on the first data volume, and the resources may be used by the terminal to forward the first data. Optionally, the first report may be, for example, a BSR. Optionally, the first report is used to request resources of a first bandwidth, where the first bandwidth is determined based on the first data volume. Optionally, the first report is used to request resources of a first duration, where the first duration is determined based on the first data volume.

[0185] Optionally, in some embodiments, when the terminal is in a connected state, after determining the first data amount, the terminal may directly send a first report based on the first data amount. Optionally, in other embodiments, when the terminal is in a non-connected state, if the terminal is configured with Small Data Transmission (SDT), then when the first data amount meets the first condition, the terminal may initiate SDT to the network device based on the first data amount. Optionally, the first condition may, for example, be: the first data amount is less than or equal to the threshold corresponding to the terminal's SDT. Here, the terminal may determine the first data amount in an appropriate manner to determine whether to initiate SDT. Optionally, the SDT may be used to send the above-mentioned first data.

[0186] Optionally, in some embodiments, when sending the first report, the terminal may send the first report via a first signaling, for example, the first report may be carried by the first signaling. The first signaling may be, for example, a BSR medium access control control element (MAC CE) signaling.

[0187] Optionally, in some embodiments, when the terminal sends the first report through the first signaling, if the terminal's current uplink resources (e.g., currently available uplink resources) can carry the first signaling and the subheader of the first signaling, the terminal can use the uplink resources to send the first signaling. If the terminal's current uplink resources cannot carry the first signaling and the subheader of the first signaling, the terminal can send a first request, which can be used to request a first resource for carrying the first signaling and the subheader of the first signaling. After that, the terminal can use the requested first resource to send the first signaling.

[0188] Optionally, in some embodiments, the first request may be a scheduling request (SR). Optionally, when sending the SR, the terminal may use any SR configuration to send the SR, or may use an SR configuration associated with a second channel to send the SR, wherein the second channel may be a channel used by the terminal to forward the first data to the network device. The SR configuration may be pre-configured by the network device to the terminal.

[0189] Step 2103: The network device schedules second resources to the terminal based on the first report.

[0190] Optionally, in some embodiments, the network device may determine a first amount of data to be forwarded by the terminal based on the first report, and then schedule a second resource sufficient to carry the first amount of data for the terminal based on the first amount of data.

[0191] Step 2104: The terminal forwards the first data to the network device based on the second resource.

[0192] In the above embodiment, the terminal will determine the first data volume and will send a first report to the network device based on the first data volume. The first data volume can be the data volume of the first data, and the first data can be the data to be forwarded by the first device through the terminal. The first report can be used to indicate the first data volume of the terminal and request the network device to schedule resources for the first data based on the first data volume, that is, the first report can be a buffer status report (BSR). It can be seen that the embodiment of the present disclosure provides a method for how a terminal sends a BSR for the scenario of "the first device forwards data through the terminal", so that the terminal can successfully send the BSR to the network device, and the network device can successfully schedule resources for the terminal to carry the data to be forwarded based on the BSR, ensuring that the terminal can successfully forward the data to be forwarded using the resources scheduled by the network device, ensuring the successful forwarding of the data of the first device by the terminal, and ensuring communication stability.

[0193] The sending method involved in the embodiment of the present disclosure may include at least one of steps 2101 to 2104. For example, step 2101 may be implemented as an independent embodiment, step 2102 may be implemented as an independent embodiment, and step 2101+S2102 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0194] 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.

[0195] FIG2B is a flow chart of a sending method according to an embodiment of the present disclosure. As shown in FIG2B , the present disclosure embodiment relates to a sending method for use in a communication system 100, the method comprising:

[0196] Step 2201: The terminal determines a first data volume.

[0197] For a detailed description of step 2201, please refer to the above embodiment description.

[0198] Step 2202: The network device sends a second signaling to the terminal.

[0199] Optionally, the second signaling may be used, for example, to indicate that the terminal does not support or is no longer configured to forward the first data.

[0200] Step 2203: The terminal does not send or cancels sending the first report or the first request.

[0201] Optionally, in some embodiments, when the terminal receives the second signaling, it indicates that the terminal currently does not support or is no longer configured to forward the first data of the first device, that is, the terminal will not forward the first data at all. At this time, the terminal does not need to send the first report to request resources for carrying the first data, and, based on the fact that the terminal does not need to send the first report, the terminal does not need to send the first request to request the first resources for carrying the first report. The terminal may not send the first report, or cancel the sending of the triggered or suspended first report, or cancel the sending of the triggered or suspended first request.

[0202] Optionally, in some other embodiments, when there is another situation, the terminal may not send or cancel sending the first report or the first request. Optionally, when the current uplink resources of the terminal can carry the first data, it means that the terminal can successfully send the first data through the current uplink resources. At this time, the terminal does not need to send the first report to request the resources for carrying the first data, and, based on the fact that the terminal does not need to send the first report, the terminal does not need to send the first request to request the first resources for carrying the first report. The terminal may not send the first report, or cancel sending the triggered or suspended first report, or cancel sending the triggered or suspended first request, and the terminal may forward the first data to the network device through the current uplink resources.

[0203] Alternatively, in some other embodiments, when the terminal is in a non-connected state, if the terminal is configured with SDT, then when the first data volume meets the first condition, the terminal may initiate SDT to the network device based on the first data volume. Optionally, the first condition may be, for example: the first data volume is less than or equal to the threshold corresponding to the terminal's SDT. Here, the terminal may determine the first data volume in an appropriate manner to determine whether to initiate SDT. Optionally, the SDT may be used to send the above-mentioned first data. At this time, since the SDT is sufficient to send the first data, the terminal does not need to send the first report to request resources for carrying the first data, and based on the fact that the terminal does not need to send the first report, the terminal does not need to send the first request to request the first resources for carrying the first report. The terminal may not send the first report, or cancel the sending of the triggered or suspended first report, or cancel the sending of the triggered or suspended first request, and the terminal may forward the first data to the network device through SDT.

[0204] In the above embodiment, when the current uplink resources of the terminal can carry the first data, it means that the current uplink resources of the terminal are sufficient for the terminal to forward the first data. At this time, the terminal does not need to send the first report to request the network device to schedule resources for the terminal to forward the first data. The terminal may not send the first report, or cancel the sending of the triggered or suspended first report, thereby avoiding unnecessary sending of the first report and saving communication resources. In addition, in the above embodiment, when the terminal receives the second signaling for indicating that the terminal does not support or is no longer configured to forward the first data, it means that the terminal will no longer forward the first data at this time. The terminal also does not need to send the first report to request the network device to schedule resources for the terminal to forward the first data. At this time, the terminal may not send the first report, or not send the first request for requesting resources to carry the first report, or cancel the sending of the triggered or suspended first report, or cancel the sending of the triggered or suspended first request, thereby avoiding unnecessary sending of the terminal and saving communication resources.

[0205] The sending method involved in the embodiment of the present disclosure may include at least one of steps 2201 to 2203. For example, step 2201 may be implemented as an independent embodiment, step 2202 may be implemented as an independent embodiment, and step 2201+S2202 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0206] 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.

[0281] The following is an exemplary introduction to the above method.

[0282] 1. A method for obtaining the amount of data to be transmitted by a low-power device when the terminal assists the low-power device in accessing the device;

[0283] a) Low-power devices are Ambient IoT devices;

[0284] b) The amount of data to be transmitted can be counted per LCH; (for example, if the network configures a logical channel for auxiliary transmission of data from low-power devices to the base station, the amount of data to be transmitted on this logical channel can be counted)

[0285] 2. Based on 1, when the terminal assists the low-power device to access, the amount of data to be transmitted is obtained according to this method and a specific type of BSR (connected terminal) is reported to the base station;

[0286] 3. Based on 1, when a non-connected terminal assists a low-power device in accessing, the amount of pending data in UL is obtained according to this method (non-connected terminal);

[0287] a) As an embodiment, for example, a terminal configured with SDT determines whether the conditions for sending SDT are met based on the amount of pending data in UL.

[0288] 4. Based on 1, the data volume statistics can be based on the data received from low-power devices, that is, buffered data from ambient devices, that is, the data volume decoded through tag backscatter (Type 1);

[0289] 5. Based on 1, the amount of data to be transmitted can be based on the amount of data to be transmitted received from low-power devices, that is, the amount of data to be transmitted by ambient devices (for the agent's understanding, the difference from type 1 is that this is the amount of data decoded from backscatter before being tagged, and is only the amount of data to be transmitted reported by ambient devices) (Type 2):

[0290] a) As an embodiment, the terminal may obtain the amount of data to be transmitted from the low-power device;

[0291] Considering the signaling overhead of data volume reporting, it may be quantized. For example, if 0 is reported, it is within 1000 bits, and if 2 is reported, it is within 2000 bits.

[0292] 6. Based on 1, the amount of data to be transmitted can be estimated based on the data transmission capability that the terminal intends to provide or plans to provide for low-power device data transmission (Type 3):

[0293] b) As an embodiment, the amount of data evaluated based on the terminal capability may be smaller than that of type 2.

[0294] For example, if a terminal needs to perform other transmissions, CW transmission can only support the collection of half the data volume, and cannot collect all the data. In this case, the terminal estimates the amount of data to be transmitted based on its own capabilities (or the resources given to the tag).

[0295] 7. Based on 2, the triggering conditions for a specific type of BSR include at least the following:

[0296] b) Data received from low-power device (trigger condition 1)

[0297] c) The amount of data received from the low-power device waiting to be transmitted (trigger condition 2)

[0298] d) A CW is sent to the low-power device for backscatter transmission of data to the terminal; (trigger condition 3)

[0299] 8. Based on 2, if a specific type of BSR is sent to the base station, if there is an uplink authorization at this time, the specific type of BSR MAC CE and its subheader can be placed, then the specific type of BSR MAC CE is sent, otherwise the SR is sent;

[0300] c) As an embodiment, for an SR triggered by a specific type of BSR, any SR configuration may be used for transmission;

[0301] d) As an embodiment, for an SR triggered by a specific type of BSR, the SR configuration associated with the logical channel configured by the terminal for uploading data for a low-power terminal may be used for transmission (if a logical channel configured for uploading data for a low-power terminal exists);

[0302] 9. Based on 2, for a specific type of BSR trigger, if it is in the pending state, if there is an uplink authorization at this time, the specific type of BSR MAC CE can be placed, and the triggered specific type of BSR will be canceled;

[0303] 10. Based on 2, for a specific type of BSR trigger, if it is in the pending state, it can be canceled (Cancel) if the network configuration terminal no longer supports uploading data for low-power terminals;

[0304] Based on 2, for an SR triggered by a specific type of BSR, if it is in the pending state, it can be canceled (Cancel) when the network configuration terminal no longer supports uploading data for low-power terminals.
