Description

[0002] In a dual connectivity (DC) scenario, maintaining the connection between the master cell group (MCG) and the SCG at the same time consumes a lot of energy.

[0047] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0048] SCG activation and deactivation

[0049] In the dual connectivity (DC) scenario, it will consume a lot of energy for the terminal device to maintain the connection between the master cell group (MCG) and the SCG at the same time. Therefore, some communication technologies have introduced the deactivation state of SCG. When the terminal device does not have much data service, the SCG can be deactivated. When the SCG is deactivated, the terminal device will not transmit the physical uplink shared channel (PUSCH), sounding reference signal (SRS) and channel state information (CSI) report on the SCG, and the terminal device does not need to monitor the physical downlink control channel (PDCCH) of the SCG or receive the downlink shared channel (DL-SCH), thereby achieving the purpose of saving power for the terminal device. When the data service of the terminal device increases again and the amount of data reaches the SCG activation threshold, the master node (MN), secondary node (SN) or terminal device can initiate the SCG activation process. The activation process of the SCG can be triggered by the terminal device receiving an SCG activation media access control element (MAC CE).

[0050] Figure 2 is an example diagram of the activation and deactivation of an SCG. As shown in Figure 2, as the data service (i.e., user traffic) of the terminal device gradually increases, the connection setup is started at time t1, and the primary cell (PCell) begins to serve the terminal device. As the data service increases, at time t2, SCG addition occurs. The added SCG is in an activated state, that is, the SCG can be used to transmit user services. In the subsequent process, the user service gradually decreases, and at time t3, the SCG or secondary cell (SCell) is deactivated. At time t4, due to the increase in user service, the SCG or SCell is activated. Due to the continued low traffic volume, at time t5, the inactivity timer expires and the connection is released.

[0051] Activating an SCG requires some time. This means there's a delay between when the SCG activation conditions are met and when the SCG is successfully activated. For ease of description, the time between when the SCG activation conditions are met and when the SCG is successfully activated is referred to as the SCG activation time. The SCG activation time depends on the actions taken by the terminal device on the deactivated SCG.

[0052] In extreme cases, the SCG activation time can be the same as the SCG addition scenario (the terminal device takes the same action to deactivate the SCG as when releasing the SCG). That is, the upper limit of the SCG activation time can be the SCG addition duration (that is, the primary secondary cell (PSCell) addition delay). In this scenario, the SCG activation time can be increased by the PSCell addition delay T config_PSCell Indicates. T config_PSCell Can meet: T config_PSCell =T RRC_delay +T processing +T search +T Δ +T PSCell_DU +2ms. Among them, T RRC_delay Indicates the radio resource control (RRC) processing delay, which can be 16ms. processing Indicates the physical layer processing delay, which may include software loading delay and data structure and cache initialization delay. The software loading delay is, for example, 20ms, and the data structure and cache initialization delay is, for example, 20ms, for a total of 40ms. search It can represent the PSS / SSS detection delay. Its value can be 0 when the target cell is known. Δ It can represent the downlink fine synchronization delay, and its value range can be 5-160ms. PSCell_ DU It can represent the uncertain delay of obtaining the first physical random access channel (PRACH) occasion of PSCell, and the value is about 10ms.

[0053] As can be seen from the above formula, the SCG activation time can reach approximately 200ms. A longer SCG activation time will affect the communication process. For example, in low-traffic scenarios with short periods of low activity, the SCG may be frequently activated and deactivated. A longer SCG activation time will significantly affect the possibility of MCG data offloading.

[0054] It can be seen from the above formula that the downlink fine synchronization delay is a major delay that affects the upper limit of the SCG activation time. For the downlink fine synchronization delay, if the terminal device can always maintain the downlink fine synchronization of the deactivated SCG, the delay can be completely eliminated. In some implementations, by continuously performing radio link monitoring (RLM) and / or beam failure detection (BFD) on the deactivated SCG, the downlink fine synchronization of the deactivated SCG can be maintained, thereby eliminating the downlink fine synchronization delay. Relevant technologies (such as 3GPP TS37.340) state that if the network device is configured, the terminal device can perform RLM and BFD operations on the deactivated SCG.

[0055] Continuously performing BFD and / or RLM on a deactivated SCG may introduce significant measurement and energy consumption overhead on the terminal device. However, adopting a relaxed measurement mechanism may result in delayed or inaccurate downlink fine synchronization, thereby increasing the SCG activation time.

[0056] FIG3 is a schematic flow chart of a method for activating an SCG according to an embodiment of the present application to solve the above problem. The method shown in FIG3 can be executed by a terminal device. The method shown in FIG3 can include step S310.

[0057] Step S310: The terminal device performs BFG and / or RLM on the deactivated SCG.

[0058] Performing BFG and / or RLM on a deactivated SCG can achieve downlink fine synchronization for the deactivated SCG in advance, thereby reducing the SCG activation time. As shown in Figure 4, if BFG and / or RLM are performed before the SCG activation conditions are met, the SCG activation time can exclude the downlink fine synchronization delay, thereby reducing the SCG activation time.

[0059] The activation of BFG and / or RLM requires certainty or prediction. In other words, BFG and / or RLM are only executed after BFG and / or RLM are confirmed to be activated. If BFG and / or RLM are not activated, BFG and / or RLM are not executed. In other words, BFG and / or RLM do not need to be continuously activated. In other words, BFD and / or RLM may not be executed for part of the time period when the SCG is in the deactivated state. Therefore, this application can reduce energy consumption in terminal devices.

[0060] As shown in FIG5 , the duration of continuous RLM and / or BFD for the deactivated SCG may be T1. Based on the present application, RLM and / or BFD may be enabled at a predicted moment, and the duration of performing RLM and / or BFD is T2. It is understandable that, under the same RLM and / or BFD detection cycle, the longer the duration of performing RLM and / or BFD, the greater the energy consumption of the terminal device. As can be seen from FIG5 , within the duration T1-T2, the terminal device may not perform RLM and / or BFD, thereby reducing the energy consumption of the terminal device.

[0061] The activation of BFD and / or RLM may be determined based on prediction information of the data traffic of the terminal device. The prediction information may be information related to the data traffic of the terminal device after the current moment.

[0062] The prediction information is related to data traffic, and data traffic is related to SCG activation. Therefore, based on the prediction information, the future SCG activation status can be predicted. In other words, the activation of BFD and / or RLM can be determined based on the predicted SCG activation status. Based on this, the present application can predict the future SCG activation status based on the data traffic prediction information of the terminal device, and thus, based on the future SCG activation status, turn on BFD and / or RLM in a targeted manner, thereby reducing the downlink fine synchronization delay during the SCG activation time while reducing the energy consumption of the terminal device.

[0063] In some embodiments, the prediction information can be determined based on the first information. For example, the first information can be input into a first model, and the first model can output the prediction information. In other words, the first model can be used to determine the prediction information based on the first information.

[0064] It should be noted that the prediction information obtained based on the first model can not only be used in the embodiments provided in this application, but can also be applied to other technical solutions that require prediction information, and this application does not impose any restrictions on this.

[0065] Optionally, the first information may include one or more of the following information: location information of the terminal device, data arrival information of the terminal device, current time, serving cell information of the terminal device, neighboring cell information of the terminal device, carrier frequency information of the terminal device, BSR-related information of the terminal device, SR-related information of the terminal device, SCG activation threshold configured by the network device, first threshold, first duration, and second duration. These pieces of information are explained below respectively.

[0066] Location information of the terminal device

[0067] In some embodiments, the location information of the terminal device may be used to indicate the location of the terminal device. For example, the location information of the terminal device may include one or more of the following: coordinates of the terminal device, and a relative position to a reference point (eg, a network device).

[0068] In some embodiments, the location information of a terminal device can be used to indicate the movement of the terminal device. For example, the location information of a terminal device can include one or more of the following: multiple locations of the terminal device over a period of time, the locations of N consecutive points of the terminal device, the movement speed of the terminal device, and the displacement of the terminal device over a period of time. N is a positive integer. If the location information of a terminal device includes multiple pieces of location information, the location information of the terminal device can be used to indicate the movement of the terminal device.

[0069] In some embodiments, the location information of the terminal device may include the current location information of the terminal device and / or the historical location information of the terminal device. For example, the location information of the terminal device may include one or more of the following information of the terminal device: the current location, the locations of N consecutive points before the current location, the location information within a second time window before the current location, etc.

[0070] The present application does not limit the device for determining the location information of the terminal device. For example, the location information of the terminal device can be measured by the terminal device and / or the network device.

[0071] Data arrival information of terminal devices

[0072] In some embodiments, the data arrival information may be used to indicate the amount of data arriving at the terminal device and / or the time of data arrival.

For example, the data arrival information may include one or more of the following information: the current data arrival amount, the data arrival amount and / or data arrival time for M consecutive sampling points before the current time, and the data arrival amount and / or data arrival time within a second time window before the current time. Where M is a positive integer.

[0074] In some embodiments, the data arrival information may be used to indicate the arrival of uplink and / or downlink data.

[0075] This application does not limit the device that obtains data arrival information. For example, data arrival information can be determined by a terminal device and / or a network device. When data arrival information is determined from the perspective of a terminal device, the arrival of uplink and / or downlink data can be referred to as the arrival of uplink and / or downlink data on the terminal device side. When data arrival information is determined from the perspective of a network device, the arrival of uplink and / or downlink data can be referred to as the arrival of uplink and / or downlink data on the network device side.

[0076] Current moment

[0077] The current time may be, for example, a time at which the first information is used. For example, the current time may be a time at which the prediction information is determined based on the first information.

[0078] This application does not limit the method of indicating a moment. As an implementation method, a moment can be represented by universal time. For example, the moment can be 23:12:34:23 milliseconds on July 19, 2023. As another implementation method, a moment can be represented by a time unit. A time unit may include, for example, a frame, a subframe, an OFDM symbol, etc. The current moment and other moments in this application can be represented by the above methods.

For example, the serving cell information may include one or more of the following information: an identifier of the serving cell, a signal quality of the serving cell. The identifier of the serving cell may include a physical cell identifier (PCI). The signal quality of the serving cell may include one or more of the following: reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), and signal-to-interference-plus-noise ratio (SINR).

P is a positive integer.

For example, neighboring cell information may include one or more of the following: neighboring cell identification and neighboring cell signal quality. The neighboring cell identification may include PCI. The neighboring cell signal quality may include one or more of the following: RSRP, RSRQ, and SINR.

For example, BSR-related information may include one or more of the following: the BSR at the current moment, the BSRs of R consecutive sampling points before the current moment, and the BSR within a second time window before the current moment. Where R is a positive integer.

For example, SR-related information may include one or more of the following: the SR at the current moment, the SRs of S consecutive sampling points before the current moment, and the SR within a second time window before the current moment. Where S is a positive integer.

[0089] The first threshold

[0090] The first threshold may be used to determine whether to activate the SCG based on the predicted data traffic. For example, if the predicted data traffic is greater than or equal to the first threshold, the SCG may be activated.

[0091] The first threshold may meet one or more of the following: configured by the network device, pre-set, pre-defined, or specified by a standard.

[0092] First duration

[0093] The first duration is associated with the first threshold. The first duration may be used to indicate that the SCG may be activated if the predicted data traffic volume is greater than or equal to the first threshold for a duration that reaches the first duration. In some embodiments, the duration may be a duration. That is, the SCG may be activated if the predicted data traffic volume is greater than or equal to the first threshold for a duration that reaches the first duration.

[0094] The first duration may satisfy one or more of the following: configured by the network device, pre-set, pre-defined, or specified by a standard.

[0095] SCG activation threshold

[0096] The SCG activation threshold can be used to determine whether to activate the SCG based on actual data traffic. That is, the SCG activation threshold can be a threshold used to activate the SCG in related art or a conventional threshold used to activate the SCG. For example, if the actual data traffic is greater than or equal to the SCG activation threshold, the SCG can be activated.

[0097] The SCG activation threshold may meet one or more of the following: configured by the network device, pre-set, pre-defined, or specified by a standard.

[0098] The first threshold may be the same as or different from the SCG activation threshold. For example, the first threshold and the SCG activation threshold may be the same threshold. In other words, the SCG activation threshold may also be used to determine whether to activate the SCG based on predicted data traffic. Alternatively, the first threshold and the SCG activation threshold may be different values, so that different thresholds are used to activate the SCG in different situations.

[0099] Second duration

[0100] The second duration is related to the SCG activation threshold and can be used to indicate that the SCG is activated when the actual data traffic is greater than or equal to the SCG activation threshold for a period of time that reaches the second duration.

[0101] The second duration may satisfy one or more of the following: configured by the network device, pre-set, pre-defined, or specified by a standard.

[0102] It should be noted that some of the information in the first information may be unique to the network device, that is, it can only be obtained from the network device. For example, information configured by the network device (such as the SCG activation threshold configured by the network device, the first threshold configured by the network device, the first duration configured by the network device, and the second duration configured by the network device) may be unique to the network device. Some of the information in the first information may be unique to the terminal device, that is, it can only be obtained from the terminal device. Some of the information in the first information can be collected, monitored or obtained by the network device and / or the terminal device. For example, the location information of the terminal device may be collected in real time by the terminal device and / or the network device.

[0103] In the related art, the prediction of data arrival reflects the total data arrival of the network device, that is, the total data arrival of all terminal devices served by the network device. The tidal characteristics of data arrival of network devices make their data arrival patterns easier to predict. Therefore, the prediction performance of the total data arrival of network devices is better. For a single terminal device, the arrival of data services is sudden. Therefore, it is more difficult to make predictions based purely on the data volume of a single terminal device than to predict the data arrival of a network device. Currently, except for research related to discontinuous reception (DRX), there are few literatures discussing the prediction of the data volume of a single terminal device. The present application proposes that, based on the first information, prediction information of data traffic with terminal device as the granularity can be determined. Among them, the information included in the first information can take into account the similarity of the movement rules of the terminal devices (for example, the same trajectory for commuting every day), thereby improving the accuracy of data traffic prediction. In addition, the first information can include more contextual information (such as location information, timestamp information). With the supplement of these contextual information, the prediction accuracy of the data service of the terminal device is higher. It can be seen from this that the traffic information at the terminal device granularity is predicted based on the content included in the first information proposed in this application, the prediction accuracy is higher, and the service experience of the terminal device is better.

[0104] As described above, the prediction information can be determined based on the first information based on the first model. The first model can be an artificial intelligence (AI) model. For example, the type of the first model can be: a supervised model, a semi-supervised model, or a reinforcement learning model. This application does not limit the training process of the first model. The first model used below can be a model that has been trained and can be used for reasoning.

[0105] It should be noted that the first model can be deployed on a terminal device or on a network device. In the case where the first model is deployed on a terminal device, if part or all of the information in the first information is configured or obtained by the network device, the network device can send the corresponding information to the terminal device. For example, the network device can send one or more of the first threshold, SCG threshold, first duration, and second duration configured by the network device to the terminal device. In the case where the first model is deployed on a network device, if part or all of the information in the first information is obtained by the terminal device, the terminal device can send the corresponding information to the network device. For example, the terminal device can send the location information of the terminal device obtained by its own measurement to the network device.

[0106] In some embodiments, the prediction information may include one or more of the following information: the target data traffic of the terminal device within the first time window; whether the target data traffic reaches the first threshold; whether the duration for the target data traffic to reach the first threshold reaches the first duration; whether the target data traffic reaches the SCG activation threshold; whether the duration for the target data traffic to reach the SCG activation threshold reaches the second duration; the probability that the target data traffic reaches the first threshold; the probability that the duration for the target data traffic to reach the first threshold reaches the first duration; the probability that the target data traffic reaches the SCG activation threshold; the probability that the duration for the target data traffic to reach the SCG activation threshold reaches the second duration; the target data traffic The first target moment when the target data traffic reaches the first threshold; the second target moment when the duration of target data traffic reaching the first threshold reaches the first duration; the third target moment when the target data traffic reaches the SCG activation threshold; the fourth target moment when the duration of target data traffic reaching the SCG activation threshold reaches the second duration; the duration from the current moment of the terminal device to the first target moment; the duration from the current moment of the terminal device to the second target moment; the duration from the current moment of the terminal device to the third target moment; the duration from the current moment of the terminal device to the fourth target moment; BSR-related information of the terminal device in the first time window; and, SR-related information of the terminal device in the first time window.

[0107] The first time window may be a period of time after the current moment. The first time window may meet one or more of the following: configured by the network device, pre-set, pre-defined, or specified by a standard.

[0108] It should be noted that the BSR related information of the terminal device in the first time window may include the BSR size in the first time window. The SR related information of the terminal device in the first time window may include the requested resource amount in the first time window.

[0109] Based on the prediction information, the second information may be determined. The activation of RLM and / or BFD may be determined based on the second information. It is understood that the second information may directly guide the communication process.

[0110] The second information may include one or more of the following: whether RLM and / or BFD are enabled, the enabling time of RLM and / or BFD, and the third duration, which will be described below.

[0111] In some embodiments, if the second information indicates to enable RLM and / or BFD, the terminal device may enable RLM and / or BFD. For example, upon receiving or calculating the second information, the terminal device may immediately enable RLM and / or BFD according to the instruction of the second information.

[0112] In some embodiments, if the second information indicates a start time, the terminal device may start RLM and / or BFD at the start time.

[0113] The third duration is used to indicate the time remaining until the RLM and / or BFD is turned on. For example, the third duration may be the time between the current moment and the turn-on moment. In some embodiments, if the second information indicates the third duration, the terminal device turns on RLM and / or BFD after the third duration has elapsed. For example, for the terminal device, the terminal device may turn on RLM and / or BFD at the moment corresponding to the third duration after the moment the second information is received or calculated. In some embodiments, the prediction information is input into the second model, and the second model may output the second information. That is, the second model may be used to determine the second information based on the prediction information. In some embodiments, the prediction information may include the second information. For example, the information output by the first model may also include the second information. In other words, the first model may also have the functionality of the second model.

[0114] The second model may be an AI model. For example, the type of the second model may be a supervised model, a semi-supervised model, or a reinforcement learning model. This application does not limit the training process of the second model.

[0115] The second model can be deployed on the terminal device, or the second model can be deployed on the network device.

[0116] In some embodiments, the method shown in FIG3 may further include step S305 .

[0117] Step S305: The network device sends an indication message to the terminal device. The indication message may be related to the terminal device performing RLM and / or BFD on the deactivated SCG. The content of the indication message may also be different depending on the device deployed in the second model.

[0118] In some embodiments, when the second model is deployed on a network device, the instruction information may include first instruction information. The first instruction information may be used to instruct the terminal device to enable RLM and / or BFD. In other words, the network device may determine the second information and, based on the second information, determine the first instruction information to instruct the terminal device to enable RLM and / or BFD.

[0119] The first indication information may include, for example, one or more of the following: second information, a start command, and a first timer.

[0120] In the case where the first indication information includes the second information, the terminal device may determine the time to start RLM and / or BFD according to the second information.

[0121] The enable command can be used to instruct the terminal device to enable RLM and / or BFD. The network device can determine the time to issue the enable command based on the second information. If the second information only instructs the terminal device to enable RLM and / or BFD, the network device can immediately issue the enable command to instruct the terminal device to enable RLM and / or BFD. If the second information includes the enable time of RLM and / or BFD, the network device can issue the enable command at the enable time. If the second information includes a third duration, the network device can wait for the third duration before issuing the enable command.

[0122] The first timer can be used to determine the start time of beam failure detection and / or wireless link monitoring. For example, if the first indication information includes the first timer, the terminal device can start the first timer in response to receiving the first indication information. In response to the expiration of the first timer, the terminal device can turn on RLM and / or BFD. If the second information includes the start time and / or the third duration of RLM and / or BFD, the network device can immediately issue a start command and indicate the first timer in the first indication information. The duration of the first timer can be determined based on the start time and / or the third duration. For example, the duration of the first timer is equal to the difference between the current time and the start time or the third duration.

[0123] When the second model is deployed on a terminal device, the indication information may include third indication information. That is, the network device may send the third indication information to the terminal device. The terminal device may obtain the second information based on the third indication information and local information of the terminal device in combination with the prediction information.

[0124] Exemplarily, the third indication information may be used to indicate one or more of the following information: information related to the network device required by the second model; whether the network device sends information related to the network device; and whether the activation of RLM and / or BFD is determined based on prediction information.

[0125] The information related to the network device required for the second model may include one or more of the following: information configured on the network device, information measured on the network device, etc. For example, the information related to the network device required for the second model may include one or more of: a first threshold configured on the network device, a first duration configured on the network device, an SCG activation threshold configured on the network device, and a second duration configured on the network device.

[0126] If the third indication information indicates that the activation of RLM and / or BFD is not determined based on the prediction information, RLM and / or BFD may continue to be performed, or downlink fine synchronization may be performed within the SCG activation time. In other words, if the third indication information indicates that the activation of RLM and / or BFD is not determined based on the prediction information, a fallback to the solution of the related art may be performed.

[0127] Whether RLM and / or BFD is enabled based on the prediction information can be indirectly indicated by whether the network device sends information related to the network device. For example, if the network device does not send information related to the network device, it can fall back to the solution of the related art.

[0128] In some embodiments, the network device may proactively send the third indication information. For example, the network device may periodically send the third indication information. Alternatively, the network device may send the third indication information in response to a first event occurring. The first event may, for example, include SCG deactivation.

[0129] In some embodiments, the terminal device may send a second request to the network device, where the second request may be used to request the network device to send third indication information. In response to the network device receiving the second request, the network device may send the third indication information. It will be appreciated that in some embodiments, the network device will only send the third indication information if it receives the second request. For example, after the terminal device obtains a target data flow rate, if the target data flow rate is greater than the current data flow rate or the previously predicted target data flow rate, the terminal device may send a second request to the network device.

[0130] When the second model is deployed on the network device, the terminal device may send second indication information to the network device. The second indication information may be used to indicate one or more of the following information: information related to the terminal device required by the second model; whether the terminal device sends information related to the terminal device; and whether the activation of RLM and / or BFD is determined based on the prediction information.

[0131] The information related to the terminal device required by the second model may be obtained by the terminal device through self-measurement. For example, the information related to the terminal device may include location information of the terminal device.

[0132] Whether the terminal device sends the information related to the terminal device may include: agreeing to send the information related to the terminal device, and not agreeing to send the information related to the terminal device.

[0133] If the second indication information indicates that the activation of RLM and / or BFD is not determined based on the prediction information, RLM and / or BFD may continue to be performed, or downlink fine synchronization may be performed within the SCG activation time. In other words, if the second indication information indicates that the activation of RLM and / or BFD is not determined based on the prediction information, a fallback to the solution of the related art may be used.

[0134] Whether RLM and / or BFD is enabled based on the prediction information can be indirectly indicated by whether the terminal device sends information related to the terminal device. For example, if the terminal device does not send information related to the terminal device, it can fall back to the solution of the related art.

[0135] In some embodiments, the terminal device may proactively send the second indication information to the network device. In some embodiments, the network device may send a first request to the terminal device, requesting the terminal device to send the second indication information. In response to the terminal device receiving the first request, the terminal device may send the second indication information. It will be understood that in some embodiments, the terminal device will only send the second indication information after receiving the first request.

[0136] It should be noted that if the first indication information, the second indication information, or the third indication information contains multiple pieces of information, the multiple pieces of information may be reported together or independently. For example, if the second indication information includes information related to the terminal device and whether the terminal device sends information related to the terminal device, these two pieces of information may be included in one RRC message for transmission, or may be stored in two independent RRC messages and reported separately.

[0137] When the second model is deployed on the terminal device, the terminal device can directly enable beam failure detection and / or radio link monitoring at an appropriate time according to the second information output by the second model. For example, when the second information only includes whether to enable the beam failure detection and / or radio link monitoring, the terminal device can immediately enable RLM and / or BFD without waiting. Alternatively, when the second information includes the enable time and / or third duration of RLM and / or BFD, the terminal device can wait until the enable time or wait for the third duration before enabling RLM and / or BFD.

[0138] The first model and the second model can be deployed on the same device or on different devices.

[0139] As an implementation method, both the first model and the second model can be deployed on the terminal device. The terminal device can obtain the prediction information and the second information locally. This approach requires high computing power and energy consumption from the terminal device, but it can avoid reporting sensitive terminal device information to network equipment, thereby improving the security and reliability of the communication process.

[0140] As another implementation, both the first model and the second model can be deployed on the network device. When part or all of the first information is acquired or collected by the terminal device, the terminal device needs to continuously report the information to the network device, resulting in a large amount of data transmission.

[0141] As another implementation, the first model can be deployed on the terminal device, and the second model can be deployed on the network device. After the terminal device obtains the prediction information, it can determine whether to report the prediction information to the network device based on the prediction information. The network device can input the second information reported by the terminal device into the second model to determine whether to enable RLM and / or BFD.

[0142] It should be noted that, as mentioned above, the first model may also include the functionality of the second model. In this case, the transmission of one or more of the first indication information, the second indication information, and the third indication information described above may be performed depending on whether the first model is deployed on a terminal device or a network device.

[0143] Figure 6 is a schematic flow chart of another method for activating an SCG provided by an embodiment of the present application. The method shown in Figure 6 can be executed by a terminal device and a network device. The method shown in Figure 6 can include step S610.

[0144] Step S610: The terminal device receives a first activation command sent by the network device.

[0145] The first activation command can be used to activate the SCG of the terminal device in advance. Activating the SCG of the terminal device in advance may include: activating the SCG before the SCG activation condition is met. For example, before the SCG activation condition is met, some or all operations related to SCG activation may be performed in advance. For example, the time to activate the SCG may be predicted, and the process of activating the SCG may be started before the predicted time to activate the SCG. Based on the present application, even if the terminal device has not yet met the conditions for activating the SCG at the current moment, the SCG activation may be started. At the moment when the SCG activation condition is met, the SCG activation process has been executed for a period of time, thereby reducing the SCG activation time. Optionally, the SCG activation condition may include, for example, that the actual data traffic of the terminal device reaches the SCG activation threshold. In other words, the SCG activation condition may include that the actual data traffic is greater than or equal to the SCG activation threshold.

[0146] It should be noted that this application does not limit the method for determining the SCG activation threshold associated with the first activation command. For example, the SCG activation threshold can be used to determine whether to activate the SCG based on actual data traffic. Alternatively, the SCG activation threshold can be used to determine whether to activate the SCG based on predicted data traffic. The SCG activation threshold can meet one or more of the following: pre-configured, network device configured, or protocol specified.

[0147] For example, before the SCG activation conditions are met, RRC processing and / or physical layer processing can be performed in advance, thereby reducing the RRC processing delay and / or physical layer processing delay. As can be seen from the above, RRC processing delay and physical layer processing delay are the main delays that affect the upper limit of the SCG activation time. Therefore, based on this application, the SCG activation time can be significantly reduced.

[0148] It should be noted that the first activation command may be a MAC CE command. In other words, the first activation command may also be referred to as SCG early activation of MAC CE.

[0149] For ease of understanding, an exemplary explanation is given below using FIG. 7 .

[0150] As shown in Figure 7, in the early SCG activation scheme, RRC processing and physical layer processing can be performed in advance before the data volume reaches the SCG activation threshold. As can be seen from Figure 7, compared with related technologies, the early RRC processing and physical layer processing greatly reduces the time required to activate the SCG.

[0151] In some embodiments, the first activation command may be determined based on predicted information about the data traffic of the terminal device. For a description of the predicted information, reference may be made to the above. For example, by predicting the target data traffic of the terminal device, it may be determined that the data traffic of the terminal device meets the SCG activation condition at a first moment in the future, and the first activation command may be determined based on the first moment.

[0152] In some embodiments, the prediction information can be determined based on the first information. In some embodiments, the first information can be input into a first model to determine the prediction information. For details about the prediction information, the first information, or the first model, please refer to the above and will not be repeated here.

[0153] In some embodiments, the first activation command may be determined based on third information. The third information may be determined based on prediction information. The third information may include, for example, one or more of the following: whether the first activation command is sent, the time at which the first activation command is sent, and a fourth duration. The fourth duration may be used to indicate the length of time since the first activation command was sent.

[0154] In some embodiments, the time at which the network device sends the first activation command can be determined based on the third information. For example, the network device can send the first activation command immediately after determining the first activation command. Alternatively, the network device can send the first activation command a fourth time period after determining the first activation command or at the time the first activation command is sent.

[0155] In some embodiments, the time at which the terminal device executes the first activation command can be determined based on the third information. For example, upon receiving the first activation command, the terminal device may immediately begin executing the first activation command. Alternatively, the terminal device may begin executing the first activation command a fourth time period after receiving the first activation command. In another example, the network device may send a second timer to the terminal device. The second timer may be used to determine the time at which the first activation command is executed. Exemplarily, the terminal device may execute the first activation command when the second timer expires.

[0156] The third information may be determined based on a third model. The third model may be used to determine the third information based on the predicted information. In other words, the input of the third model may be the predicted information, and the output of the third model may be the third information.

[0157] In some embodiments, the third information may be included in the prediction information. For example, the prediction information output by the first model may include the third information. In other words, the first model may include the functionality of the third model, i.e., the first model may also output the third information.

[0158] The third model can be deployed on terminal devices or network devices.

[0159] When the third model is deployed on the network device, the network device may send the first activation command according to the third information.

[0160] For example, when the third information only includes whether to send the first activation command, the network device can immediately send the first activation command. Alternatively, when the third information includes the sending time and / or the fourth duration of the first activation command, the network device can wait until the sending time or wait for the fourth duration before sending the first activation command. Alternatively, when the third information includes the sending time and / or the fourth duration of the first activation command, the network device can immediately send the first activation command and the second timer. After receiving the second timer, the terminal device starts the second timer. When the second timer times out, the terminal device starts to execute the first activation command.

[0161] In the case where the third model is deployed on the terminal device, the terminal device needs to send the third information to the network device so that the network device sends the first activation command according to the third information.

[0162] The first model and the third model can be deployed on the same device or on different devices.

[0163] As an implementation method, both the first and third models can be deployed on the terminal device. The terminal device can obtain the prediction information and the third information locally. This approach requires high computing power and energy consumption from the terminal device, but it can avoid reporting sensitive terminal device information to network equipment, thereby improving the security and reliability of the communication process.

[0164] As another implementation, both the first model and the third model can be deployed on the network device. When part or all of the first information is acquired or collected by the terminal device, the terminal device needs to continuously report this information to the network device, resulting in a large amount of data transmission.

[0165] As another implementation method, the first model can be deployed on the terminal device, and the third model can be deployed on the network device. Since the third model is not deployed on the terminal device, this method can reduce the energy consumption and computing power requirements of the terminal device. In addition, what the terminal device reports to the network device can be prediction information rather than the first information. Since the first information contains sensitive information of the terminal device, this method can also avoid reporting the sensitive information of the terminal device to the network device. Optionally, after the terminal device obtains the prediction information, it can determine whether to report the prediction information to the network device based on the prediction information, thereby reducing the amount of information that needs to be reported. For example, the terminal device can determine whether the SCG needs to be activated. The terminal device can report the prediction information to the network device only when the SCG needs to be activated.

[0166] In some embodiments, if the terminal device fails to activate the SCG based on the first activation command (for example, the first activation command fails to be decoded), the terminal device may activate the SCG based on a second activation command. The second activation command may be used to activate the SCG if the SCG meets the activation conditions. It is understood that if the actual data traffic of the terminal device meets the SCG activation conditions, the network device may issue the second activation command to activate the SCG. For example, the second activation command may be the SCG activation command in the related art.

[0167] It should be noted that the first activation command and the second activation command can be distinguished by an explicit identifier.

[0168] It should be noted that the embodiments described above can be implemented individually or in combination. For example, the activation of RLM and / or BFD can be determined based on the predicted information of the data traffic of the terminal device, and the first activation command can be sent based on the predicted information. As shown in Figure 8, the above two solutions are combined, RRC processing and physical layer processing can be performed before the SCG activation time, and the downlink fine synchronization delay can also be reduced. As can be seen from Figure 8, the SCG activation time can be reduced to less than 50ms.

[0169] For ease of understanding, the present application is described in detail below through Examples 1 to 3.

[0170] Example 1

[0171] Embodiment 1 provides a method for predicting data traffic of a terminal device.

[0172] In the first embodiment, the first information can be input into the first model to obtain prediction information. The prediction information can be input into the fourth model. The fourth model can output a data traffic prediction result for the terminal device. The fourth model can include the second model and / or the third model described above. That is, the data traffic prediction result for the terminal device output by the fourth model can include the second information and / or the third information.

[0173] The first information may be information collected / monitored in real time by the terminal device and / or the network device. The first information may be used to predict the arrival of data from the terminal device to obtain prediction information.

[0174] The first information may include one or more of the following information.

[0175] 1) Terminal device location information. For example, the terminal device location information may include one or more of the following: the current location, the locations of N consecutive points before the current location, or the location within a second time window before the current location. The length of the second time window is defined by the network.

[0176] 2) Data arrival information. For example, data arrival information may include: uplink / downlink data arrival information on the terminal device side and / or uplink / downlink data arrival information on the network device side. Data arrival information may include the amount of data arriving and / or the time of data arrival at the following times: the current time, N consecutive sampling points before the current time, or within a second time window before the current time.

[0177] 3) Current moment.

[0178] 4) Serving cell information. For example, the serving cell information may include one or more of the following: PCI, RSRP, RSRQ, SINR. The serving cell information may be information corresponding to the following time periods: the current moment, N consecutive sampling points before the current moment, or within a second time window before the current moment.

[0179] 5) Neighboring cell information. For example, neighboring cell information may include one or more of the following: PCI, RSRP, RSRQ, SINR. Neighboring cell information may be information corresponding to the following time periods: the current moment, N consecutive sampling points before the current moment, or within a second time window before the current moment.

[0180] 6) Carrier frequency information.

[0181] 7) BSR information: For example, the BSR information may include one or more of the following: the BSR at the current moment, the BSRs of N consecutive sampling points before the current moment, and the BSR within the second time window before the current moment.

[0182] 8) SR requested resource amount. For example, the SR requested resource amount may include one or more of the following: the requested resource amount within the second time window before the current moment)

[0183] 9) SCG activation threshold configured on network devices.

[0184] 10) A first threshold configured on the network device. The first threshold is used to determine whether to activate the SCG based on the predicted information. For example, the SCG may be activated when the predicted service data arrival volume exceeds the first threshold. Optionally, the first information may also include a first duration. If the first duration exists, the SCG may be activated if the predicted service data arrival volume continues to exceed the first threshold within the first duration.

[0185] It should be noted that, among the above information, except for the SCG activation threshold configured by the network device, the first threshold configured on the network side, and the first duration configured by the network device, which are unique information of the network device, the rest of the information can be collected / obtained by the network device or the terminal device.

[0186] The first model can be used to perform predictions based on the data. The first model can be an AI model. For example, the first model can be a supervised model, a semi-supervised model, or a reinforcement learning model. This application does not limit the specific form and training process of the first model. In Example 1, Example 2, or Example 3, it is assumed that the first model has been trained and can directly perform model inference.

[0187] The prediction information may indicate the data arrival prediction result of the terminal device. The prediction information may include one or more of the following information.

[0188] 1) The amount of data arriving in the first time window after the current time of the terminal device. The first time window can be defined by the network device.

[0189] 2) Whether the data of the terminal device reaches the SCG activation threshold in the first time window after the current moment.

[0190] 3) The probability that the data of the terminal device reaches the SCG activation threshold in the first time window after the current moment.

[0191] 4) The moment when the data in the first time window after the current moment of the terminal device reaches the SCG activation threshold.

[0192] 5) The moment when the amount of data arrival reaches the SCG activation threshold.

[0193] 6) The time from the current moment to the time when the data arrival amount reaches the SCG activation threshold.

[0194] 7) Whether the amount of data arriving at the terminal device within the first time window after the current moment reaches a first threshold.

[0195] 8) The probability that the amount of data arriving at the terminal device within the first time window after the current moment reaches a first threshold.

[0196] 9) The moment when the amount of data arriving in the first time window after the current moment of the terminal device reaches the first threshold.

[0197] 10) The moment when the amount of data arrival reaches the first threshold.

[0198] 11) The time from the current moment to the time when the data arrival amount reaches the first threshold.

[0199] 12) BSR information of the terminal device in the first time window after the current moment.

[0200] 13) The amount of SR resources requested by the terminal device in the first time window after the current moment.

[0201] The fourth model can be used to further process the output results (prediction information) of the first model, so as to obtain results / commands that can directly guide the optimization of the communication network (represented below by the terminal device data traffic prediction results).

[0202] The terminal device data traffic prediction result may include, for example, a result related to RLM and / or BFD activation (i.e., the second information). The result related to RLM and / or BFD activation may include one or more of the following: whether RLM and / or BFD is activated, the time when RLM and / or BFD is activated (i.e., the activation time), and the time until RLM and / or BFD is activated (i.e., the third duration).

[0203] The terminal device data traffic prediction result may include, for example: SCG activation MAC CE related results (i.e., third information). The SCG activation MAC CE related results may include one or more of the following information: whether to send the SCG early activation MAC CE, the time when the SCG early activation MAC CE is sent (i.e., the sending time), and the time until the SCG early activation MAC CE is started (i.e., the fourth time).

[0204] Example 2

[0205] The terminal device can enable RLM and / or BFD measurements for the deactivated SCG based on the RLM and / or BFD activation related results and / or network side indication commands in the data traffic prediction results of the terminal device obtained locally, so as to achieve downlink precise synchronization of the deactivated SCG in advance, reduce the SCG activation time and reduce the energy consumption of the terminal device.

[0206] The following three situations are described with examples.

[0207] Case 1: The fourth model is deployed on the terminal device, and the terminal device determines to enable RLM and / or BFD based on local information and information on the network device side.

[0208] If the fourth model is deployed on the terminal device, the terminal device needs to obtain network side information (such as the first threshold and first duration configured on the network side) and calculate the RLM and / or BFD activation related results in combination with the local information of the terminal device.

[0209] If the result only indicates to enable RLM and / or BFD, the terminal device enables RLM and / or BFD operations without waiting.

[0210] If the result includes the time to start RLM and / or BFD or the time until RLM and / or BFD is started, the terminal device starts RLM and / or BFD measurement when the start time arrives or the time until RLM and / or BFD is started has passed.

[0211] The terminal device may obtain the information of the network device in method 1 or method 2.

[0212] Method 1: The terminal device proactively sends a request (i.e., a second request) to the network device based on the predicted information, requesting information from the network device. For example, if the terminal device uses the first model to determine the amount of data arriving within the second time window after the current moment of the terminal device, and this amount of data arrival is higher than the previously predicted result, the terminal device may request the network device to determine whether to activate the SCG by setting the SCG activation threshold and / or the first threshold.

[0213] Method 2: The network device proactively sends network device information. For example, when the SCG is deactivated, the network device may send the SCG activation threshold and / or the first threshold to the terminal device.

[0214] Case 2: The fourth model is deployed on a network device, which determines whether to enable RLM and / or BFD based on local information.

[0215] The network can send the RLM and / or BFD activation results to the terminal device. The terminal device determines the time to activate RLM and / or BFD based on the RLM and / or BFD activation results. The terminal device's determination process is similar to that in scenario 1 and will not be repeated here.

[0216] The network device may send an RLM and / or BFD enable command to the terminal device based on the RLM and / or BFD enablement related results to indicate whether to enable RLM and / or BFD.

[0217] Optionally, if the RLM and / or BFD activation related result only indicates that RLM and / or BFD are to be activated, the network device may send an activation command to the terminal device. Based on the activation command, the terminal device activates measurement.

[0218] Optionally, if the RLM and / or BFD activation-related result includes the time to activate RLM and / or BFD or the time until RLM and / or BFD is activated, the network device may wait for the time to be reached or the time until RLM and / or BFD is activated before issuing an RLM and / or BFD activation command to the terminal device. Based on the activation command, the terminal device activates measurement.

[0219] Optionally, if the RLM and / or BFD activation-related results include the time to activate RLM and / or BFD or the time until RLM and / or BFD is activated, the network device may send an RLM and / or BFD activation command and a first timer to the terminal device. The terminal device may start measurement after the first timer expires. The first timer duration may be equal to the time until RLM and / or BFD is activated, or equal to the difference between the time to activate RLM and / or BFD and the current time.

[0220] Case 3: The fourth model is deployed on a network device. The network device can combine local information with information from the terminal device to determine whether to enable RLM and / or BFD.

[0221] When the fourth model is deployed on a network device and it is impossible to determine whether to enable RLM and / or BFD by relying solely on information obtained from the network, it is necessary to make a judgment based on the information of the terminal device (such as the location information of the terminal device).

[0222] The process of the network device obtaining the information of the terminal device may include: the network device side sends an information request command (ie, a first request) to the terminal device; and according to the request command, the terminal device returns second indication information.

[0223] The second indication information may include: consent to report information and / or information of the terminal device requested by the network; or disagreement to report information of the terminal device requested by the network. If the terminal device disagrees to report, the data flow prediction of the terminal device cannot be completed, and the terminal device may fall back to the technical solution in the related art, that is, continuing to perform RLM and / or BFD or performing downlink fine synchronization within the SCG activation time.

[0224] If the second indication information includes both the consent to report information and the terminal device information requested by the network device, these two pieces of information may be reported together or separately. For example, the consent to report information and the terminal device information requested by the network may be included in a single RRC message for transmission, or may be stored in two separate RRC messages for separate reporting.

[0225] Example 3

[0226] In embodiment three, the terminal device can receive the SCG to activate MAC CE in advance and complete RRC processing and physical layer processing according to the instruction command of the network device, thereby reducing the SCG activation time.

[0227] If the fourth model is deployed on a terminal device, the terminal device may report the locally calculated SCG activation MAC CE related results to the network side. If the fourth model is deployed on a network device, the network device may locally calculate the SCG activation MAC CE related results.

[0228] In some embodiments, if the SCG activation MAC CE related result only indicates sending the SCG early activation MAC CE, the network device may send the SCG early activation MAC CE to the terminal device. Upon receiving the MAC CE, the terminal device may start RRC processing and physical layer processing.

[0229] In some embodiments, the SCG early activation MAC CE may explicitly indicate that the MAC CE is an early activation command, rather than the SCG activation MAC CE in the related art. If the SCG early activation fails (e.g., the SCG early activation MAC CE decoding fails), the SCG activation method in the related art may be reverted to, i.e., the SCG activation MAC CE in the related art may be used to activate the SCG.

[0230] If the SCG MAC CE activation related results include the time of sending the SCG early activation MAC CE or the time until the SCG early activation MAC CE is started, the network device can send the SCG early activation MAC CE and a second timer. The second timer can be used to indicate the execution time of the SCG early activation MAC CE, and the second timer duration is equal to the difference between the time of the SCG early activation MAC CE and the current time or the time until the SCG early activation MAC CE is started. When the second timer times out, the terminal device can start RRC processing and physical layer processing.

[0231] If the SCG Activation MAC CE related results include the time of sending the SCG Early Activation MAC CE or the time until the start of sending the SCG Early Activation MAC CE, the network device can wait until the time of SCG Early Activation MAC CE or the time until the start of sending the SCG Early Activation MAC CE, and then send the SCG Early Activation MAC CE to the terminal device. The terminal device can then start RRC processing and physical layer processing.
