The wireless communication system 100 may include a network device 110 and a terminal device 120. The network device 110 may be a device that communicates with the terminal device 120.

Optionally, the wireless communication system 100 may include multiple network devices, and each network device may include other numbers of terminal devices within its coverage area. This application embodiment does not limit this.

[0030] Optionally, the wireless communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in this embodiment.

Cellular phones and smart home devices communicate without relaying communication signals through a base station.

[0033] The network device in this application embodiment can be a device used to communicate with a terminal device. This network device can also be called an access network device or a wireless access network device, such as a base station. In this application embodiment, the network device can refer to a radio access network (RAN) node (or device) that connects the terminal device to the wireless network. A base station can broadly encompass, or be replaced by, various names including: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, transmitting and receiving point (TRP), transmitting point (TP), master MeNB, auxiliary SeNB, multi-mode radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, micro base station, relay node, donor node, or similar, or a combination thereof.

In other examples, a helicopter or drone can be configured as a device to communicate with another base station.

[0035] In some deployments, the network device in this application embodiment may refer to a CU or a DU, or the network device may include both a CU and a DU. The gNB may also include an AAU.

[0036] Network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenario in which the network devices and terminal devices are located.

[0037] It should be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform).

[0038] Traffic reporting

[0039] In the current uplink traffic (or data arrival status) reporting mechanism, network devices can configure uplink traffic reporting via the ul-TrafficInfoReportingConfig in the radio resource control (RRC) signaling otherConfig. After receiving this RRC configuration, the terminal device can monitor and report the traffic of the corresponding service.

[0040] The uplink traffic reporting configuration can include service-related identifiers, such as QoS flow identifiers (QFI) and / or PDU session identifiers (PDU-SessionID), so that the terminal device can monitor and report the traffic of related services based on the identifiers.

[0041] For example, the contents of the RRC signaling otherConfig are as follows:

[0042] In some embodiments, after obtaining the above configuration, the terminal device can report traffic through UL-Traffic signaling in the terminal device's auxiliary information (such as UEAssistanceInformation) message. The content reported by the terminal device may include the PDU session identifier, QFI, data arrival time, data arrival jitter range, and traffic cycle.

[0043] For example, the UL-Traffic signaling includes the following:

[0044] In some embodiments, the data arrival time can be indicated by the parameter burstArrivalTime.

[0045] In some embodiments, the data reaching the jitter range can also be understood as time offset or time bias, which can be indicated by the parameter jitterRange.

[0046] In some embodiments, burstArrivalTime can be used to indicate the expected arrival time of the first packet in the Data Burst associated with the QoS flow. If the UE provides both burstArrivalTime and jitterRange, burstArrivalTime is used as a reference time for the indicated jitter range.

[0047] In some embodiments, if burstArrivalTime is specified as a reference time, the specified time in 10ns from the origin is refDays*86400*1000*100000+refSeconds*1000*100000+refMilliSeconds*100000+refTenNanoseconds (if burstArrivalTime is indicated as reference time, the indicated time in 10ns unit from the origin is). The refDays field specifies the sequential number of days (with day count starting at 0) from 00:00:00 on Gregorian calendar date 6 January, 1980 (start of GPS time).

[0048] In some embodiments, if burstArrivalTime is specified as reference SFN-AndSlot, it refers to the uplink timing of the closest SFN and slot of the PCell with the specified sequence number.

[0049] In some embodiments, jitterRange can be used to indicate the maximum deviation of the arrival time of the first packet in a data burst compared to the time indicated by burstArrivalTime and the periodicity of the data bursts. lowerBound indicates a negative deviation, while upperBound indicates a positive deviation.

[0050] In some embodiments, the jitterRange field can only be reported together with burstArrivalTime, or after burstArrivalTime has been reported.

[0051] In some embodiments, the value 0dot5 corresponds to 0.5ms, the value ms1 corresponds to 1ms, and so on. The value beyondMs7 indicates that the jitter boundary is greater than 7ms. A value of 0 means that there is no data burst arrival time deviation compared to the indicated burstArrivalTime.

[0052] It should be noted that the current uplink traffic reporting only reports the data arrival time, but not the data volume corresponding to that arrival time.

[0053] In the field of sideline communication, there are also mechanisms for traffic reporting. Terminal devices can report traffic through sideline auxiliary information (such as SL-UE-AssistanceInformationNR) signaling.

[0054] In the sideline traffic reporting mechanism, the information reported by the terminal device may include traffic period, time offset, data arrival amount, and the identifier of the sideline QoS flow.

[0055] For example, the SL-UE-AssistanceInformationNR signaling contains the following content:

[0056] In some embodiments, the aforementioned data arrival volume can be indicated by the parameter messageSize. In some embodiments, messageSize is used to indicate the maximum TB size based on the observed traffic pattern.

[0057] In some embodiments, messageSize can be identified by an 8-bit variable, that is, messageSize can represent 0-255, where different values ​​correspond to different bit ranges.

[0058] In some embodiments, the value of messageSize can be found in Table 1.

[0059] Table 1

[0060] As can be seen from the above description, in the current traffic reporting mechanism, the uplink traffic reporting does not report the data volume, but only the arrival time; while the downlink traffic reporting reports the data arrival volume and data arrival time, but only reports the arrival status of existing data.

[0061] Based on this, the inventors believe that traffic prediction (or data arrival prediction) has broad application prospects in communication systems. For example, network devices can configure more reasonable sleep and / or wake-up times for terminal devices based on traffic prediction, such as configuring the duration of discontinuous reception (DRX) to save power consumption of terminal devices. Furthermore, network devices can configure reasonable pre-configured resources for terminal devices based on traffic prediction, such as configuring reasonable configured grant (CG) resources to reduce the occupation of invalid resources and improve resource utilization.

[0062] Therefore, embodiments of this application propose that the first terminal device can indicate the predicted data arrival amount through the first information. In this way, the recipient of the first information can utilize the first information to optimize network performance or communication performance. For example, the recipient of the first information can determine the sleep time and / or wake-up time of the first terminal device based on the first information to save energy consumption. As another example, the recipient of the first information can configure reasonable pre-configured resources for the first terminal device based on the first information to improve resource utilization.

[0063] The method embodiments of this application will be described below.

[0064] Figure 2 is a schematic flowchart of a wireless communication method provided in an embodiment of this application. The method shown in Figure 2 is described from the perspective of the interaction between a first terminal device and a network device (or a second terminal device). The first terminal device and the second terminal device can be the terminal device 120 shown in Figure 1, and the network device can be the network device 110 shown in Figure 1.

[0065] The method shown in Figure 2 may include step S210, which will be described below.

[0066] In step S210, the first terminal device sends a first message. For example, the first terminal device may send the first message to a network device or a second terminal device.

[0067] As an example, in an uplink transmission scenario, the first terminal device can send the first message to the network device.

[0068] As another example, in a side-sending scenario, the first terminal device can send a first message to the second terminal device.

[0069] In some embodiments, the first message may be a higher-layer message (such as an RRC message) from the first terminal device. For example, the first message may be an RRC message sent by the first terminal device to a network device. As another example, the first message may be an RRC message sent by the first terminal device to a second terminal device. Of course, the embodiments of this application are not limited to this; the first message may also be a Layer 1 or Layer 2 message. For example, the first message may be a medium access control element (MAC CE); as another example, the first message may be downlink control information (DCI); as yet another example, the first message may be sidelink control information (SCI).

[0070] In some embodiments, the first message may be auxiliary information of the first terminal device. For example, the first message may be a UE assistance information (i.e., UEAssistanceInformation) message. Another example is a side-channel UE assistance information (i.e., SL-UE-AssistanceInformationNR) message.

[0071] In some embodiments, the first message can be used by the first terminal device to send (or report) data arrival status. Alternatively, the first message can be used by the first terminal device to report traffic.

[0072] In some embodiments, the first message may include first information, which may be used to indicate the amount of data arriving at the first terminal device.

[0073] In some embodiments, the amount of data arriving as indicated by the first information is predicted. In other words, the first information is predicted. In this way, the recipient of the first information (such as a network device or a second terminal device) can use the first information to optimize network performance or communication performance.

[0074] This application does not limit the implementation method of the first information indicating the data arrival amount of the first terminal device. In some embodiments, the first information may explicitly indicate the data arrival amount of the first terminal device. In some embodiments, the first information may implicitly indicate the data arrival amount of the first terminal device.

[0075] For example, the first information may include one or more of the following: the amount of data arriving at the first terminal device within the prediction time window, the probability that the amount of data arriving at the first terminal device within the prediction time window exceeds a first threshold, and the data arrival pattern of the first terminal device corresponding to the prediction time window.

[0076] As an example, the first information may include the amount of data arriving at the first terminal device within the predicted time window.

[0077] As another example, the first information may include the probability that the amount of data arriving at the first terminal device within the prediction time window exceeds a first threshold.

[0078] As yet another example, the first information may include the data arrival pattern of the first terminal device within the predicted time window.

[0079] As another example, the first information may include the amount of data arriving at the first terminal device within the prediction time window and the probability that the amount of data arriving at the first terminal device within the prediction time window exceeds a first threshold.

[0080] As another example, the first information may include the amount of data arriving at the first terminal device within the prediction time window and the data arrival pattern of the first terminal device within the prediction time window.

[0081] As another example, the first information may include the probability that the amount of data arriving at the first terminal device within the prediction time window exceeds a first threshold and the data arrival pattern of the first terminal device within the prediction time window.

[0082] As another example, the first information may include the amount of data arriving at the first terminal device within the prediction time window, the probability that the amount of data arriving at the first terminal device within the prediction time window exceeds a first threshold, and the data arrival pattern of the first terminal device within the prediction time window.

[0083] This application does not limit the definition of the amount of data arriving at the first terminal device within the prediction time window. For example, the amount of data arriving at the first terminal device within the prediction time window may include one or more of the following: the total amount of data arriving at the first terminal device within the prediction time window, the amount of data arriving at the first terminal device at different times within the prediction time window, and the amount of data arriving at the first terminal device during different time periods (or sub-time periods) within the prediction time window.

[0084] As an example, the amount of data arriving at the first terminal device within the prediction time window can include the total amount of data arriving at the first terminal device within the prediction time window. Taking a prediction time window of 200ms as an example, the amount of data arriving at the first terminal device within the prediction time window can include the total amount of data arriving at the first terminal device within those 200ms.

[0085] As another example, the data arrival volume of the first terminal device within the prediction time window can include the data arrival volume of the first terminal device at different times within the prediction time window, that is, the data arrival volume of the first terminal device at discrete time points within the prediction time window. As a possible implementation, assuming the network device is configured to report the first information by reporting the data arrival volume at different times within the prediction time window, the data arrival volume of the first terminal device within the prediction time window can include the data arrival volume of the first terminal device at different times within the prediction time window. Taking a prediction time window of 200ms as an example, the data arrival volume of the first terminal device within the prediction time window can include the data arrival volume of the first terminal device at different times within that 200ms (such as time T1, time T2, time T3, etc.). For example, the data arrival volume of the first terminal device at time T1 is 870 bytes, at time T2 it is 160 bytes, and at time T3 it is 4189 bytes, etc.

[0086] As another example, the data arrival volume of the first terminal device within the prediction time window can include the data arrival volume of the first terminal device in different time periods within the prediction time window, that is, the data arrival volume of the first terminal device in each sub-time period within a continuous period. As a possible implementation, assuming the network device is configured to report the first information by reporting the data arrival volume in different time periods within the prediction time window, the data arrival volume of the first terminal device within the prediction time window can include the data arrival volume of the first terminal device in different time periods within the prediction time window. Taking a prediction time window of 200ms as an example, the data arrival volume of the first terminal device within the prediction time window can include the data arrival volume of the first terminal device in different time periods within that 200ms (e.g., every 40ms is a time period). That is, the first information reported by the first terminal device can be 5 data arrival volumes, where each data arrival volume is the data arrival volume within 40ms.

[0087] As another example, the amount of data arriving at the first terminal device within the prediction time window may include the amount of data arriving at the first terminal device at different times within the prediction time window and the total amount of data arriving at the first terminal device within the prediction time window.

[0088] As another example, the amount of data arriving at the first terminal device within the prediction time window may include the amount of data arriving at the first terminal device in different time periods within the prediction time window and the total amount of data arriving at the first terminal device within the prediction time window.

[0089] In some embodiments, when the first terminal device indicates the amount of data arriving at different times within a prediction time window in the first information, it may also indicate the time corresponding to the data arrival at those different times. As one possible implementation, the first information may include one or more times (i.e., discrete time points) and the amount of data arriving at each of those times. As another possible implementation, the first information may include one or more time offsets and the amount of data arriving at each of those time offsets. It should be noted that the one or more time offsets can be used to indicate the offset of the time when the data arrives at the first terminal device relative to a reference time; or, in other words, the one or more time offsets can be used to indicate the time offset of the time corresponding to the data arrival at the first terminal device relative to the reference time.

[0090] This application does not limit the way the reference time is defined. As one possible implementation, the reference time can be configured by the network device. As another possible implementation, the reference time can be predefined or preconfigured; for example, the reference time can be predefined or preconfigured as the start time of a prediction time window.

[0091] In some embodiments, the reference time can be an absolute time. For example, the reference time can be Coordinated Universal Time (UTC), system frame number, time slot, etc.

[0092] In some embodiments, the reference time can be a relative time. For example, the reference time can be the start time of the prediction time window. Alternatively, the reference time can be a relative time to the start time of the prediction time window.

[0093] In some embodiments, the amount of data arriving at the first terminal device within a predicted time window (e.g., total data arrivals, data arrivals at different times, and data arrivals over different time periods) can be indicated by the parameter messageSize. In some embodiments, messageSize is used to indicate the maximum transport block (TB) size based on the observed traffic pattern.

[0094] In some embodiments, messageSize can be identified by an 8-bit variable, that is, messageSize can represent 0-255, where different values ​​correspond to different bit ranges.

[0095] In some embodiments, the value of messageSize can be found in Table 1 mentioned above.

[0096] In some embodiments, the probability that the amount of data arriving at the first terminal device within the prediction time window exceeds a first threshold can refer to the probability that the total amount of data arriving at the first terminal device within the prediction time window exceeds the first threshold.

[0097] In some embodiments, the probability that the data arrival volume of the first terminal device exceeds a first threshold within the prediction time window can refer to the probability that the data arrival volume of the first terminal device exceeds the first threshold at different times within the prediction time window. Taking a prediction time window of 200ms as an example, the probability that the data arrival volume of the first terminal device exceeds the first threshold within the prediction time window can refer to the probability that the data arrival volume of the first terminal device exceeds the first threshold at different times (such as time T1, time T2, etc.) within the 200ms. That is, the first information reported by the first terminal device can include multiple probability values, where each probability value refers to the probability that the data arrival volume exceeds the first threshold at a given time (such as time T1). As an example, the first information reported by the first terminal device includes: the probability value at time T1 (such as 30%), the probability value at time T2 (such as 80%), the probability value at time T3 (such as 50%), etc.

[0098] In some embodiments, the probability that the data arrival volume of the first terminal device exceeds the first threshold within the prediction time window can refer to the probability that the data arrival volume of the first terminal device exceeds the first threshold in different time periods within the prediction time window. Taking a prediction time window of 200ms as an example, the probability that the data arrival volume of the first terminal device exceeds the first threshold within the prediction time window can refer to the probability that the data arrival volume of the first terminal device exceeds the first threshold in different time periods within the 200ms (e.g., every 40ms is a time period). That is, the first information reported by the first terminal device can be 5 probability values, where each probability value refers to the probability that the data arrival volume exceeds the first threshold in a 40ms time period.

[0099] In some embodiments, the probability that the amount of data arriving at the first terminal device within the prediction time window exceeds a first threshold is a value between 0% and 100%.

[0100] In some embodiments, the first threshold corresponding to the total amount of data arriving at the first terminal device within the prediction time window is different from the first threshold corresponding to the amount of data arriving at the first terminal device at different times within the prediction time window.

[0101] In some embodiments, the first threshold corresponding to the total amount of data arriving at the first terminal device within the prediction time window is different from the first threshold corresponding to the amount of data arriving at the first terminal device in different time periods within the prediction time window.

[0102] In some embodiments, the first threshold corresponding to the amount of data arriving at the first terminal device in different time periods within the prediction time window is different from the first threshold corresponding to the amount of data arriving at the first terminal device at different times within the prediction time window. In some embodiments, the first threshold corresponding to the amount of data arriving at the first terminal device in different time periods within the prediction time window is the same as the first threshold corresponding to the amount of data arriving at the first terminal device at different times within the prediction time window.

[0103] This application does not limit the value of the first threshold. For example, the first threshold may include one or more of the following: 160 bytes, 500 bytes, 1024 bytes, 2048 bytes, etc.

[0104] This application does not limit the method of obtaining the first threshold. In some embodiments, the first threshold is configured by the network device. In some embodiments, the first threshold is predefined or preconfigured. For example, the first threshold is predefined by the protocol.

[0105] In some embodiments, the data arrival pattern of the first terminal device within the predicted time window can be used by the receiver of the first information to determine the amount of data arriving at the first terminal device within the predicted time window. The first terminal device implicitly indicates the amount of data arriving through the data arrival pattern, thus eliminating the need to report detailed data amounts at every moment, which helps reduce the amount of air interface data transmitted.

[0106] In some embodiments, the data arrival pattern of the first terminal device in the predicted time window can be determined based on the first data arrival pattern and / or scaling factor.

[0107] As an example, the data arrival pattern of the first terminal device in the predicted time window can be determined based on the first data arrival pattern.

[0108] As another example, the data arrival pattern of the first terminal device within the prediction time window can be determined based on the first data arrival pattern and a scaling factor. It should be noted that in some embodiments, if the scaling factor corresponding to a certain first data arrival pattern is 1, then determining the data arrival pattern of the first terminal device within the prediction time window based on the first data arrival pattern and the scaling factor can also be understood as the data arrival pattern of the first terminal device within the prediction time window being determined based on the first data arrival pattern.

[0109] In some embodiments, the first data arrival mode can be understood as or replaced by a basic data arrival mode. The first data arrival mode may be configured by the network device, or it may be predefined or pre-configured.

[0110] This application embodiment does not limit the number of data arrival modes included in the first data arrival mode. For example, a network device can configure one or more first data arrival modes for a first terminal device; that is, the network device can configure one or more basic data arrival modes for the first terminal device. Subsequently, the first terminal device can determine the data arrival mode corresponding to the first terminal device in the prediction time window based on these one or more first data arrival modes.

[0111] This application does not limit the value of the scaling factor in its embodiments. In some embodiments, the scaling factor can be a positive integer. In some embodiments, the scaling factor can be a positive number.

[0112] In some embodiments, the data arrival pattern of the first terminal device in the predicted time window can be determined based on a first data arrival pattern and a scaling factor.

[0113] In some embodiments, the data arrival pattern of the first terminal device in the predicted time window can be determined based on a plurality of first data arrival patterns and scaling factors corresponding to the plurality of first data arrival patterns respectively.

[0114] In some embodiments, the data arrival pattern of the first terminal device within a prediction time window can be determined based on the product of the first data arrival pattern and a scaling factor. For example, if the data arrival pattern of the first terminal device within a prediction time window is determined based on one first data arrival pattern (e.g., first data arrival pattern A), the data arrival pattern of the first terminal device within the prediction time window can be equal to the product of first data arrival pattern A and a scaling factor. Alternatively, if the data arrival pattern of the first terminal device within a prediction time window is determined based on multiple first data arrival patterns (e.g., first data arrival pattern A and first data arrival pattern B), the data arrival pattern of the first terminal device within the prediction time window can be equal to the sum of the product of first data arrival pattern A and a scaling factor (e.g., scaling factor A) and the product of first data arrival pattern B and a scaling factor (e.g., scaling factor B).

[0115] To facilitate understanding, an example of determining the data arrival pattern of the first terminal device within the prediction time window is given below with reference to Figure 3.

[0116] As shown in Figure 3(a), the network device can configure one or more first data arrival modes for the first terminal device, such as configuring first data arrival mode A and first data arrival mode B. In first data arrival mode A, time T0 is the start time of the prediction time window, and data arrives at times T1 and T2 respectively; for example, a unit amount of data arrives at times T1 and T2 respectively. In first data arrival mode B, time T0 is the start time of the prediction time window, and data arrives at times T1 and T3 respectively; for example, a unit amount of data arrives at times T1 and T3 respectively. In this case, after the first terminal device predicts the amount of data arriving within the prediction time window, it can determine the corresponding data arrival mode for the first terminal device within the prediction time window based on the predicted data arrival amount, first data arrival mode A, and first data arrival mode B. For example, the first terminal device can determine that the data arrival mode corresponding to the first terminal device in the prediction time window is the sum of the product of the first data arrival mode A and the scaling factor (the scaling factor in Figure 3 is 1) and the product of the first data arrival mode B and the scaling factor (the scaling factor in Figure 3 is 2). That is, the first terminal device determines the data arrival mode corresponding to the first terminal device in the prediction time window as shown in Figure 3(b). In this way, the first terminal device can indicate the first data arrival mode A and its corresponding scaling factor, and the first data arrival mode B and its corresponding scaling factor in the first information, so as to reduce signaling overhead.

[0117] In some embodiments, the first message may include other information in addition to the first information. For example, the first message may also include one or more of the following: reference time, time offset, and first identifier.

[0118] For an explanation of reference time and time offset, please refer to the above text; it will not be repeated here.

[0119] In some embodiments, the first identifier can be used to indicate the QoS flow corresponding to the data arrival volume. Exemplarily, the first identifier may include one or more of the following: QFI, an identifier of the PDU session. As an example, the first identifier may include a QFI. As another example, the first identifier may include an identifier of the PDU session. As yet another example, the first identifier may include both a QFI and an identifier of the PDU session.

[0120] In some embodiments, the same first identifier may correspond to a set of reference times and time offsets. For example, the same QFI may correspond to a set of reference times and time offsets.

[0121] In some embodiments, different first identifiers may correspond to multiple sets of reference times and time offsets. For example, different QFIs may correspond to multiple sets of reference times and time offsets. Taking QFIs including QFI 1 and QFI 2 as an example, QFI 1 may correspond to one set of reference times and time offsets, while QFI 2 may correspond to another set of reference times and time offsets.

[0122] The content of the first information and other information included in the first message have been introduced above. The configuration of the first information will be introduced below.

[0123] In some embodiments, the network device may send configuration information to the terminal device. This configuration information may be used to instruct the first terminal device on relevant configurations for sending the first information; or, in other words, the configuration information may be used by the first terminal device to determine how to send the first information, such as how to report the first information to the network device or how to report the first information to the second terminal device. In other words, in this embodiment, the first terminal device may send the first information based on this configuration information.

[0124] This application embodiment does not limit the content of the configuration information. For example, the configuration information may include one or more of the following: first indication information, second threshold, first identifier, data volume reporting mode, and configuration of a first timer.

[0125] In some embodiments, the configuration information may include one of the information described above. As an example, the configuration information may include first indication information. As another example, the configuration information may include a second threshold. As yet another example, the configuration information may include a first identifier. As yet another example, the configuration information may include a data volume reporting mode. As yet another example, the configuration information may include a configuration of a first timer.

[0126] In some embodiments, the configuration information may include multiple of the information described above. As an example, the configuration information may include first indication information and a second threshold. As another example, the configuration information may include first indication information and a first identifier. As yet another example, the configuration information may include first indication information, a first identifier, and a quantity reporting mode. As yet another example, the configuration information may include a second threshold, a first identifier, and a first timer configuration. As yet another example, the configuration information may include first indication information, a second threshold, a first identifier, a data volume reporting mode, and a first timer configuration.

[0127] It should be noted that the configuration information may include any one or more combinations of the above information. The above examples are only examples, and other combinations will not be listed for the sake of brevity.

[0128] In some embodiments, the aforementioned first indication information can be used to indicate whether the first terminal device supports storing and reporting the data arrival amount. In some embodiments, if the network device supports the first terminal device storing and reporting the data arrival amount, the first terminal device can report the data arrival amount once at regular intervals (i.e., send the first information once at regular intervals). That is, if the network device supports the first terminal device storing and reporting the data arrival amount, the first terminal device can report the data arrival amount periodically. In some embodiments, if the network device does not support the first terminal device storing and reporting the data arrival amount, the first terminal device can report the predicted data arrival amount after each data arrival amount prediction (i.e., send the first information).

[0129] In some embodiments, the second threshold can be used to indicate a data volume threshold for the amount of data arriving at the first terminal device. In some embodiments, if the data arrival volume predicted by the terminal device is lower than the second threshold, the first terminal device may not report the data arrival volume (i.e., not send the first information). In some embodiments, if the data arrival volume predicted by the terminal device is higher than or equal to the second threshold, the first terminal device may report the data arrival volume (i.e., send the first information).

[0130] In some embodiments, the second threshold is set for the total amount of data arriving at the first terminal device within the prediction time window.

[0131] In some embodiments, the second threshold is set for the amount of data arriving at the first terminal device at different times within the prediction time window.

[0132] In some embodiments, the second threshold is set for the amount of data arriving at the first terminal device at different time periods within the prediction time window.

[0133] The embodiments of this application do not limit the value of the second threshold. For example, the second threshold can be 160 bytes, 320 bytes, 500 bytes, 1000 bytes, etc.

[0134] For more information about the first identifier, please refer to the above text. For the sake of brevity, it will not be repeated here.

[0135] In some embodiments, the data volume reporting mode described above can be used to indicate the amount of data arriving at the first terminal device. Exemplarily, the data volume reporting mode may include one or more of the following: a first reporting mode, a second reporting mode.

[0136] As an example, the data volume reporting mode can include the first reporting mode.

[0137] As another example, the data volume reporting mode can include a second reporting mode.

[0138] As yet another example, data reporting modes can include a first reporting mode and a second reporting mode.

[0139] In some embodiments, the first reporting mode can be used to indicate the amount of data arriving at the first terminal device during different time periods within the prediction time window.

[0140] In some embodiments, the second reporting mode can be used to instruct the first terminal device to report the data arrival volume at different times within the prediction time window. That is, the second reporting mode can instruct the first terminal device to report the data arrival volume at discrete time points within the prediction time window and the corresponding time points.

[0141] In some embodiments, the first timer described above can be used by the first terminal device to send first information. For example, the first terminal device can determine whether to send the first information and / or the time to send the first information based on the first timer. Alternatively, in some embodiments, the first timer can be used by the first terminal device to report data arrival volume. For example, the first terminal device can determine whether to report data arrival volume and / or the time to report data arrival volume based on the first timer.

[0142] In some embodiments, during the operation of the first timer, the first terminal device sends the first information. That is, from the start of the first timer to its expiration, the first terminal device continuously sends the first information. In this case, the first timer can be understood as or referred to as the activation timer.

[0143] In some embodiments, the first terminal device does not send the first information during the operation of the first timer. That is, the first terminal device does not send the first information from the start of the first timer until the first timer expires, but sends the first information when the first timer is not running. In this case, the first timer can be understood as or referred to as a deactivated timer.

[0144] This application embodiment uses a first timer to determine whether to send the first information, so that the first terminal device can send the first information or report the data arrival amount when needed, which helps to reduce useless data transmission and reduce the power consumption of the first terminal device.

[0145] This application does not limit the method of carrying the above configuration information. In some embodiments, the above configuration information may be carried in a higher-level message (such as an RRC message). As an example, the above configuration information may be carried in a UL-TrafficInfoReportingConfig message or its extended message. However, this application is not limited to this; for example, the above configuration information may be carried in a MAC CE or DCI.

[0146] In some embodiments, after receiving the above configuration information, the first terminal device may send first information to the network device or the second terminal device based on the configuration information.

[0147] As mentioned above, the amount of data arriving reported by the first terminal device can be predicted. The following section introduces the model for predicting the amount of data arriving.

[0148] In some embodiments, the amount of data arrival reported by the first terminal device is predicted by the first terminal device based on the first model.

[0149] In some embodiments, the first model may be deployed on the first terminal device side.

[0150] In some embodiments, the input to the first model may include one or more of the following: the amount of data arriving at the first terminal device at different time periods within the observation time window, the amount of data arriving at the first terminal device at different times within the observation time window, a first identifier, and auxiliary information of the first terminal device.

[0151] As an example, the input to the first model may include the amount of data arriving at the first terminal device at different time periods within the observation time window.

[0152] As another example, the input to the first model may include the amount of data arriving at the first terminal device at different times within the observation time window.

[0153] As yet another example, the input to the first model may include the amount of data arriving at the first terminal device at different time periods within the observation time window and a first identifier.

[0154] As yet another example, the input to the first model may include the amount of data arriving at the first terminal device at different times within the observation time window and a first identifier.

[0155] As another example, the input to the first model may include the amount of data arriving at the first terminal device at different time periods within the observation time window, the first identifier, and auxiliary information of the first terminal device.

[0156] As yet another example, the input to the first model may include the amount of data arriving at the first terminal device at different times within the observation time window, the first identifier, and auxiliary information of the first terminal device.

[0157] In some embodiments, the amount of data arriving at the first terminal device within the observation time window may include the total amount of data arriving at the first terminal device within the observation time window. Taking a 200ms observation time window as an example, the amount of data arriving at the first terminal device within the observation time window may include the total amount of data arriving at the first terminal device within those 200ms.

[0158] In some embodiments, the data arrival volume of the first terminal device within the observation time window may include the data arrival volume of the first terminal device in different time periods within the observation time window, that is, the data arrival volume of the first terminal device in each sub-time period within a continuous period. Taking a 200ms observation time window as an example, the data arrival volume of the first terminal device within the observation time window may include the data arrival volume of the first terminal device in different time periods within the 200ms (e.g., every 10ms is a time period), that is, the data arrival volume within each 10ms is counted every 10ms within the 200ms. As shown in Figure 4, the first terminal device can count the data arrival volume in different time periods within the observation time window, and then predict the data arrival volume in different time periods within the prediction time window.

[0159] In some embodiments, the amount of data arriving at the first terminal device within the observation time window can include the amount of data arriving at the first terminal device at different times within the observation time window, that is, the amount of data arriving at the first terminal device at discrete time points within the observation time window. Taking a 200ms observation time window as an example, the amount of data arriving at the first terminal device within the observation time window can include the amount of data arriving at the first terminal device at different times (such as T1, T2, T3, etc.) within the 200ms. For example, the amount of data arriving at the first terminal device at time T1 is 870 bytes, at time T2 is 160 bytes, and at time T3 is 4189 bytes, etc. As shown in Figure 5, the first terminal device can count the amount of data arriving at different times (such as T0, T1, T2, T3, etc.) within the observation time window, and then predict the amount of data arriving at different times (such as T4, T5, etc.) within the prediction time window.

[0160] In some embodiments, when the first terminal device counts the amount of data arriving at different times within the observation time window, it can also count the time corresponding to the amount of data arriving at different times.

[0161] In some embodiments, the observation time window and the prediction time window described above may be time-separated. For example, in the examples of Figures 4 and 5, the observation time window and the prediction time window are time-separated.

[0162] In some embodiments, the observation time window and the prediction time window may be adjacent in time, or the interval between them may be very small, such as the minimum time interval between them.

[0163] For more information about the first identifier, please refer to the above text; it will not be repeated here.

[0164] In some embodiments, the auxiliary information of the first terminal device refers to the auxiliary information provided by the first terminal device, which helps to improve the prediction accuracy of the first model. This application embodiment does not limit the auxiliary information of the first terminal device. For example, the auxiliary information of the first terminal device may include one or more of the following: the location information of the first terminal device, and the current time information.

[0165] As an example, auxiliary information for the first terminal device may include its location information. In this way, the first model can combine the location information of the first terminal device to predict the amount of data arrival. For example, if the location information of the first terminal device indicates that it is located in the user's home, the probability of data arrival is likely to be relatively high. Conversely, if the location information indicates that it is located outdoors (such as on a street), the probability of data arrival is likely to be relatively low.

[0166] As another example, the auxiliary information for the first terminal device may include the current time. In this way, the first model can combine the current time information to predict the amount of data arriving. For example, if the current time information indicates that it is daytime, the probability of data arriving at the first terminal device is likely to be relatively high. Conversely, if the current time information indicates that it is nighttime, the probability of data arriving at the first terminal device is likely to be relatively low.

[0167] As another example, the auxiliary information of the first terminal device may include the location information and the current time information of the first terminal device.

[0168] In some embodiments, the output of the first model may include one or more of the following: the amount of data arriving at the first terminal device within the prediction time window, and the probability that the amount of data arriving at the first terminal device within the prediction time window exceeds a first threshold.

[0169] As an example, the output of the first model may include the amount of data arriving at the first terminal device within the prediction time window.

[0170] As another example, the output of the first model may include the probability that the amount of data arriving at the first terminal device within the prediction time window exceeds a first threshold.

[0171] As yet another example, the output of the first model may include the amount of data arriving at the first terminal device within the prediction time window and the probability that the amount of data arriving at the first terminal device within the prediction time window exceeds a first threshold.

[0172] For details regarding the amount of data arriving at the first terminal device within the prediction time window and the probability that the amount of data arriving at the first terminal device within the prediction time window exceeds the first threshold, please refer to the above text. For the sake of brevity, it will not be repeated here.

[0173] In some embodiments, the method of this application may further include: a first terminal device sending second information to a network device.

[0174] In some embodiments, the second information can be used to indicate the first terminal device's capability to predict data arrival volume. Therefore, in some embodiments, the second information can also be understood or replaced as capability information.

[0175] In some embodiments, the second information may be used to indicate one or more of the following: whether the first terminal device supports reporting data arrivals (or whether the first terminal device supports sending the first information), and the model for predicting data arrivals supported by the first terminal device.

[0176] As an example, the second information can be used to indicate whether the first terminal device supports reporting data arrivals. One possible implementation is that the first terminal device can indicate whether it supports reporting data arrivals using 1 bit of information.

[0177] As another example, the second information can be used to indicate the model for the predicted data arrivals supported by the first terminal device. As one possible implementation, the first terminal device can indicate the supported model for the predicted data arrivals by reporting one or more of the following information: model identifier, model function, model input, model output, and model usage conditions.

[0178] As an example, the first terminal device can indicate the supported models for predictive data arrival by reporting model identifiers. For instance, the first terminal device can report supported models including Model 1, Model 2, etc.

[0179] As another example, the first terminal device can indicate the model that supports the predicted data arrival volume by reporting the model's functionality.

[0180] As yet another example, the first terminal device can indicate the model's supported predicted data arrival volume by reporting the model's inputs and outputs.

[0181] As yet another example, the first terminal device can indicate the supported model for the amount of predicted data arrival by reporting the model's usage conditions (such as the number of model inputs and / or outputs).

[0182] In some embodiments, the model supported by the first terminal device for predicting data arrivals may include one or more. In this case, the terminal device may predict data arrivals based on one of the one or more models (i.e., the first model mentioned above).

[0183] In some embodiments, the transmission of the second information is triggered by a request from the network device. That is, the network device may request (or query) whether the first terminal device supports the predicted data arrival amount and / or the supported model for the predicted data arrival amount. When the first terminal device receives the request from the network device, it can provide feedback to the network device through the second information.

[0184] In some embodiments, the network device may request the first terminal device, via higher-layer signaling (such as RRC signaling), whether it supports predicted data arrivals and / or a model for the predicted data arrivals.
