[0045] Based on the above solution, the terminal receives the second information by receiving the MIB, which has the characteristic of simple implementation. Since the MIB is a broadcast message, the terminal can receive it regardless of whether it is in the Radio Resource Control (RRC) connected state, RRC idle state and / or RRC inactive state.

[0046] With reference to some embodiments of the first aspect, in some embodiments, the second network node is the same as the first network node, or the second network node is different from the first network node.

[0153] FIG1A is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0154] As shown in Figure 1A, communication system 100 includes a terminal 101 and a network device (i.e., a network node) 102. Network device 102 may include an access network device and / or a core network device. In some embodiments, the terminal may communicate with the core network node via the access network device. In other embodiments, the terminal communicates with the core network device using Non-Access Stratum (NAS) messages. The NAS messages may be transparently transmitted from the access network device to the core network device, or from the core network device to the terminal via the access network device.

[0155] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0156] In some embodiments, the terminal is also referred to as User Equipment (UE).

[0157] In some embodiments, the access network device may be, for example, a node or device that accesses a terminal to a wireless network. The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

[0158] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0159] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0160] In some embodiments, the core network device may be a single device including a first network element, or may be a plurality of devices or a group of devices, each including a first network element. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0161] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0162] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0163] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN), Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other information transmission methods, and next-generation systems based on and extending these systems. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0164] Figure 1B shows a schematic diagram of the architecture of a multi-operator core network (MOCN). In an MOCN, the CNs of multiple operators share the same radio access network (RAN). There are structures N1, N2, and N3 between the CN and the RAN. N1 can be used for non-access stratum (NAS) messages between the terminal and the network function (NF) of the CN. N2 can be used for communication between the RAN and the access management function (AMF). N3 can be used for communication between the RAN and the user plane function (UPF). The RAN of the MOCN structure is a type of shared network.

[0165] Some business data may arrive in bursts. To ensure successful data transmission, the terminal can report the arrival time of the data burst to the network device to ensure successful reception of the business data. However, when reporting the time information of the business data burst arrival, it must be reported based on a certain time. If the terminal and the network device interpret the time information reported by the terminal according to their own clocks, the problem of different understanding between the terminal and the network device may arise. In view of this,

[0166] FIG2 is an interactive diagram of an information transmission method according to an embodiment of the present disclosure. As shown in FIG2 , the present disclosure embodiment relates to an information transmission method for a communication system 100, the method comprising:

[0167] S2101: The second network node sends second information.

[0168] In some embodiments, the second network node may be any network node.

[0169] In some embodiments, the second network node may be any node currently providing a service to the terminal, or any node that is ready to or may provide a service to the terminal.

[0170] In some embodiments, the second network node may comprise an access network node.

[0171] In some embodiments, the second network node is an access network node of a serving cell of the terminal.

[0172] For example, when the terminal does not have dual connectivity, the second network node may be an access network node of a serving cell of the terminal.

[0173] For another example, when the terminal has established dual connectivity, the MN and / or SN of the second network node. In some embodiments, the second network node includes at least one of the following:

[0174] The terminal's master node MN,

[0175] The secondary node SN of the terminal;

[0176] The access network node of a cell specified by the network; the network here may include any network. For example, the core network and / or the access network. Specifically, the second network node may be the access network node of the cell specified by the terminal serving base station. For example, the second network node may be the access network node of the cell specified by the MN of the terminal. The second network node may be the access network node of the cell specified by the SN of the terminal;

[0177] The access network node of the cell agreed upon in the agreement.

[0178] In some embodiments, the second network node may also be an access network node of a non-serving cell of the terminal. For example, the non-serving cell may be a neighboring cell of the terminal's serving cell, or a cell corresponding to the terminal's geographical location when the terminal has not camped on any cell.

[0179] In some embodiments, when the network has a designated cell, the second network node may be an access network node of the designated cell.

[0180] In some embodiments, when the network does not specify a cell, the second network node may be an access node of a cell agreed upon by the protocol.

[0181] Exemplarily, the designated cell may be any serving cell of the terminal. For example, the designated cell may include but is not limited to a primary cell and / or a primary and secondary cell of the terminal.

[0182] Also illustratively, the designated cell designated by the network may be a neighboring cell of the terminal's serving cell, and / or a target cell that the terminal is about to access.

[0183] As another example, the access node of the cell agreed upon in the protocol. For example, the cell agreed upon in the protocol may include but is not limited to the primary cell and / or primary and secondary cells of the terminal.

[0184] In some embodiments, the reference time may be used to transmit any service data of the terminal. For example, the service data may include but is not limited to XR service data, augmented reality (AR) service data, and / or virtual reality (VR) service data.

[0185] In some embodiments, the reference time can also be used to send group-based service data. For example, a terminal group may include one or more terminals. These multiple terminals need to report group-based service data. The group here may include a service group and / or a device group.

[0186] For example, a terminal is connected to multiple different devices, all of which send service data to the terminal, which then reports it to the network device. Some of these devices connect to the terminal using WiFi, while others use Bluetooth. These different connections and / or changes in connections at different times can introduce jitter in data packet transmission.

[0187] Of course, the above is just an example of business data, and the specific implementation is not limited to the above example.

[0188] In some embodiments, the second network node sends the second information to the terminal.

[0189] In some embodiments, the second information is used to indicate a reference time to the terminal.

[0190] In some embodiments, the reference time indicated by the second information is determined based on the timing of the second network node. For example, the reference time specified by the second information is determined based on the timing of the second network node. The timing of the second network node may be determined based on a clock locally maintained by the first network node.

[0191] In some embodiments, the second information includes one of the following indications:

[0192] System frame number;

[0193] Subframe number;

[0194] Time slot number.

[0195] In some embodiments, the second information may further indicate a symbol number.

[0196] In some embodiments, the second network node broadcasts, multicasts, or unicasts the second information.

[0197] In some embodiments, the second network node broadcasts a system information block comprising the second information.

[0198] In some embodiments, the system information block includes, but is not limited to, a MIB.

[0199] In some embodiments, the system information block may also be a system information block on demand of the terminal.

[0200] In some embodiments, the second information may be carried in a reference time information element (IE).

[0201] S2102: The terminal sends first information.

[0202] In some embodiments, the first information indicates at least one of the following:

[0203] Data burst arrival time;

[0204] The jitter range of data arrival;

[0205] Data arrival cycle.

[0206] For example, the data burst arrival time may refer to the time when the first data packet of the burst transmission arrives at the network.

[0207] The data burst arrival time may be an average value of the first arriving data packet in the burst.

[0208] If the data packet is transmitted periodically, the first information may also indicate the period of data arrival.

[0209] The jitter range of data arrival may be caused by the time difference between the actual arrival time of the data packet and the scheduled time due to network jitter.

[0210] In some embodiments, the first information may be carried in a designated IE and reported.

[0211] Exemplarily, the designated IE may include but is not limited to Quality of Service (QoS) Uplink (Flow UL - Traffic Info) IE.

[0212] Figure 1B shows an example of QoS-FlowUL-TrafficInfo-r18. As shown in Figure 1B, the QoS-FlowUL-TrafficInfo-r18 also includes multiple IEs, including TrafficPeriodictiy-r18 that indicates the data arrival period, jitterRange-r18 that indicates the jitter range, and ReferenceTime that indicates the reference time.

[0213] In some embodiments, the terminal sends first information to the first network node.

[0214] In some embodiments, the terminal sends the first information to the first network node according to the second information.

[0215] In some embodiments, the terminal sends the first information to the first network node according to the reference time indicated by the second information.

[0216] Specifically, the terminal sends first information indicating the arrival time of the burst data according to the reference time.

[0217] In some embodiments, the terminal may not send the first information according to the reference time.

[0218] Specifically, when the terminal sends the first information indicating the jitter range and / or the burst data arrival period, the first information may not be sent based on the reference time.

[0219] In some embodiments, the first network node and the second network node may be the same or different.

[0220] In some embodiments, the terminal sends the first information to an access network node of a serving cell. In this case, the first network node may be an access network node of the serving cell of the terminal.

[0221] For example, when the terminal does not establish dual connectivity, the terminal sends the first information to the access network node of the serving cell.

[0222] For another example, when the terminal has established dual connections, the terminal may send the first information to the MN and / or the SN.

[0223] In some embodiments, the terminal sends the first information to an access network node of a non-serving cell. For example, the non-serving cell may include a target cell that the terminal is preparing to access. The target cell may be a target cell for cell handover and / or cell reselection. In another example, the non-serving cell may be a neighboring cell of the terminal's serving cell.

[0224] In some embodiments, the first network node receiving the first information may be at least one of the following:

[0225] Solution 1: The first network node is the second network node that provides the second information;

[0226] Solution 2: The first network node is an SN node. Exemplarily, Solution 2 may be an SN configured with a first SRB.

[0227] Solution 3: The first network node is the master node MN of the terminal;

[0228] Solution 4: The first network node includes the MN and SN of the terminal.

[0230] Option 1: The second information is provided by the master node MN, and the terminal sends the first information to the MN according to the reference time.

[0231] Option 2: The second information is provided by the secondary node SN, and the terminal sends the first information to the SN according to the reference time.

[0232] Option 3: The second information is provided by the MN and the SN respectively. The terminal sends the first information based on the reference time indicated by the second information provided by the MN to the MN, and the terminal sends the first information based on the reference time indicated by the second information provided by the SN to the SN. That is, in this embodiment, if both the MN and the SN provide two sets of second information, the terminal will send two sets of first information to the MN and the SN respectively according to the reference times specified by the two sets of second information. That is, the first information sent to the MN is determined based on the reference time specified by the second information provided by the MN, and / or, the first information sent to the SN is determined based on the reference time specified by the second information provided by the SN.

[0233] For solution 2, S2102 may include but is not limited to at least one of the following:

[0234] Option 1: When the first network node is a SN configured with a first SRB, the terminal sends the first information to the SN configured with the first SRB.

[0235] Option 2: If the SN is not configured with the first SRB, the terminal may send the first information to the MN.

[0236] Exemplarily, the first SRB may be any SRB configured for the SN, such as SRB3.

[0237] Exemplarily, the first SRB configured may be the SN of the primary and secondary cells of the terminal.

[0238] In some embodiments, when the first network node is a MN, the terminal sends the first information to the MN using the second SRB.

[0239] Illustratively, the first SRB may be SRB1 and / or SRB2.

[0240] Correspondingly, the first network node receives the first information sent by the terminal.

[0241] For solution 3, S2102 may include but is not limited to at least one of the following:

[0242] Regardless of whether the second information is provided by the MN, the terminal sends the first information to the MN;

[0243] Regardless of whether the SN is configured with the first SRB, the terminal sends the first information to the MN.

[0244] In summary, in the embodiment of the present disclosure, the terminal will only send the first information to the MN.

[0245] For solution 4, S2102 may include: sending the first part of the first information to the MN of the terminal and sending the second part of the first information to the SN of the terminal according to the reference time.

[0246] In some embodiments, the first portion and the second portion are at least partially different.

[0247] In some embodiments, the first portion indicates a data arrival period and / or a jitter range.

[0248] In some embodiments, the second portion is used to indicate a data burst arrival time.

[0249] In some embodiments, the first portion may not rely on a reference time.

[0250] In some embodiments, the arrival time of the data burst indicated by the second portion needs to be determined based on a reference time.

[0251] In some embodiments, the terminal sends a radio resource control (RRC) message, a media access control (MAC) signaling and / or uplink control information (UCI) including the first information.

[0252] As an optional method of solution 4, if the SN is configured with the first SRB, the first part is sent to the MN and the second part is sent to the SN configured with the first SRB. If the SN is not configured with the first SRB, the terminal can send both the first part and the second part to the MN.

[0253] In some embodiments, the terminal sends the UAI.

[0254] In some embodiments, the UAI includes first information.

[0255] In some embodiments, regardless of which of Schemes 1 to 4 a terminal uses to send the first information to the network, the following may be included: if the terminal sends the first information to the SN, the first information is sent using the first SRB. If the terminal sends the first information to the MN, the first information is sent using the second SRB. For example, the first SRB may be SRB3, and the second SRB may be SRB1 and / or SRB2. However, reporting the first information is not limited to using SRB1 to SRB3.

If the SN is not configured with the first SRB, the terminal can send both the first part and the second part to the MN.

[0330] In some embodiments, regardless of which of Schemes 1 to 4 a terminal uses to send the first information to the network, the following may be included: if the terminal sends the first information to the SN, the first information is sent using the first SRB. If the terminal sends the first information to the MN, the first information is sent using the second SRB. For example, the first SRB may be SRB3, and the second SRB may be SRB1 and / or SRB2. However, reporting the first information is not limited to using SRB1 to SRB3.

[0331] It is worth noting that: an optional embodiment in which the terminal sends the first information may refer to S2102 of FIG. 2 .

[0332] As shown in Figure 4, an embodiment of the present disclosure relates to an information transmission method for a first network node. Figure 4 illustrates an embodiment in which the first network node and the second network node are identical. Since the first network node and the second network node are identical, the second information is sent by the first network node to the terminal. Specifically, the method shown in Figure 4 may include:

[0333] S4101: Send the second information.

[0334] In some embodiments, the first network node sends the second information.

[0335] In some embodiments, the first network node may comprise an access network node.

[0336] In some embodiments, the first network node may be an access network node of a terminal serving cell.

[0337] In some embodiments, the terminal does not have dual connectivity established, and the first network node may be an access network node of a serving cell of the terminal.

[0338] In some embodiments, the terminal has dual connectivity established, and the first network node may be the MN and / or SN of the terminal.

[0339] In some embodiments, the first network node may be an access network node of a non-serving cell of the terminal. For example, the non-serving cell may include a target cell for the terminal to access. The target cell may be a target cell for cell handover and / or cell reselection. In another example, the non-serving cell may be a neighboring cell of the terminal's serving cell.

[0340] In some embodiments, the first network node may be at least one of the following:

[0341] The master node of the terminal;

[0342] Auxiliary nodes of the terminal;

[0343] The access network node of the designated cell of the network;

[0344] The access node of the cell agreed upon in the protocol.

[0345] In some embodiments, the second information sent by the first network node is determined according to a timing of the first network node. The timing of the first network node may be maintained locally by the first network node.

[0346] In some embodiments, the second information includes one of the following indications:

[0347] System frame number;

[0348] Subframe number;

[0349] Time slot number.

[0350] In some embodiments, the second information may further indicate a symbol number.

[0351] In some embodiments, the second information may be determined based on the timing of the first network node. For example, the reference time specified by the second information is determined based on the timing of the first network node. The timing of the first network node may be determined based on a clock maintained locally by the first network node.

[0352] In some embodiments, the first network node broadcasts, multicasts, or unicasts the second information.

[0353] In some embodiments, the first network node broadcasts a system information block, the system information block comprising the second information.

[0354] In some embodiments, the system information block includes, but is not limited to, a MIB.

[0355] In some embodiments, the second information may be carried in a reference time information element (IE).

[0356] Since the first network node and the second network node are the same, the optional manner of S4101 executed by the first network node may refer to S2101 of the corresponding embodiment of FIG. 2 .

[0357] S4102: Receive first information.

[0358] In some embodiments, the terminal sends first information to the first network node.

[0359] In some embodiments, the second network node may be the same as the first network node.

[0360] In other embodiments, the second network node may be different from the first network node.

[0361] The first information indicates at least one of the following:

[0362] Data burst arrival time;

[0363] The jitter range of data arrival;

[0364] Data arrival cycle.

[0365] For example, the data burst arrival time may refer to the time when the first data packet of the burst transmission arrives at the network.

[0366] The data burst arrival time may be an average value of the first arriving data packet in the burst.

[0367] If the data packet is transmitted periodically, the first information may also indicate the period of data arrival.

[0368] The jitter range of data arrival may be due to the time difference between the actual arrival time of the data packet and the scheduled time due to network jitter.

[0369] In some embodiments, the first information may be carried in a designated IE and reported.

[0370] Exemplarily, the designated IE may include but is not limited to Quality of Service (QoS) Uplink (Flow UL - Traffic Info) IE.

[0371] Figure 1B shows an example of QoS-FlowUL-TrafficInfo-r18. As shown in Figure 1B, the QoS-FlowUL-TrafficInfo-r18 also includes multiple IEs, including TrafficPeriodictiy-r18 that indicates the data arrival period, jitterRange-r18 that indicates the jitter range, and ReferenceTime that indicates the reference time.

[0372] In some embodiments, the first network node may be a network node that provides the second information. For example, the first network node may be a MN that provides the second information, or may be a SN that provides the second information.

[0373] In some embodiments, the first network node is always the MN of the terminal.

[0374] In some embodiments, the first network node may configure the SN of the first SRB for the terminal.

[0375] Exemplarily, the first SRB may be SRB 1. Also exemplarily, the SN configured with the first SRB may be the SN of the primary and secondary cells of the terminal.

[0376] In some embodiments, the first network node may be either a MN or a SN. In this case, if the first network node is a MN, the MN receives the first part of the first information from the terminal. If the first network node is a SN, the SN receives the second part of the first information from the terminal.

[0377] In some embodiments, the first portion indicates a data arrival period and / or a jitter range.

[0378] In other embodiments, the second portion is used to indicate the data burst arrival time.

[0379] In some embodiments, the first network node is a MN, and the first information sent by the receiving terminal using the second SRB.

[0380] Illustratively, the second SRB may be SRB1 and / or SRB2.

[0381] In some embodiments, the first network node is a SN, and the terminal receives first information sent using a first SRB.

[0382] Exemplarily, the first SRB may be SRB3.

[0383] In some embodiments, the first network node may also receive the first information based on a data radio bearer.

[0384] In some embodiments, the first information is carried in a Radio Resource Control (RRC) message, a Media Access Control (MAC) signaling and / or uplink control information (UCI).

[0385] In some embodiments, the first information is carried in the UAI.

[0386] It is worth noting that the second information may be provided to the terminal by a second network node different from the first network node. In this case, the first network node may also obtain the second information from the second network node. For example, the first network node obtains the second information from the second network node via an inter-base station interface, a backhaul link, or an inter-base station tunnel.

[0387] As shown in FIG5 , an embodiment of the present disclosure relates to an information transmission method for a second network node. FIG5 illustrates an embodiment in which the second network node is different from the first network node. Specifically, as shown in FIG5 , the method may include:

[0388] S5101: Send the second information.

[0389] In some embodiments, the second network node may be any network node.

[0390] In some embodiments, the second network node may be any node currently providing a service to the terminal, or any node that is ready to or may provide a service to the terminal.

[0391] In some embodiments, the second network node may comprise an access network node.

[0392] In some embodiments, the second network node is an access network node of a serving cell of the terminal.

[0393] For example, when the terminal does not have dual connectivity, the second network node may be an access network node of a serving cell of the terminal.

[0394] For another example, when the terminal has established dual connections, the MN and / or SN of the second network node.

[0395] In some embodiments, the second network node may also be an access network node of a non-serving cell of the terminal. For example, the non-serving cell may be a neighboring cell of the terminal's serving cell, or a cell corresponding to the terminal's geographical location when the terminal has not camped on any cell.

[0396] In some embodiments, the second network node may be at least one of the following:

[0397] The master node of the terminal;

[0398] Auxiliary nodes of the terminal;

[0399] The network may include any network. For example, a core network and / or an access network. Specifically, the second network node may be an access network node of a cell designated by a terminal serving base station. For example, the second network node may be an access network node of a cell designated by a MN of the terminal. The second network node may be an access network node of a cell designated by a SN of the terminal.

[0400] The access node of the cell agreed upon in the protocol.

[0401] The optional manner of S5101 here may refer to S2101 of the embodiment corresponding to Figure 2. In some embodiments, the second information includes one of the following indications: system frame number; subframe number; time slot number.

[0402] In some embodiments, the second information may further indicate a symbol number.

[0403] In some embodiments, the second network node broadcasts, multicasts, or unicasts the second information.

[0404] In some embodiments, the second network node broadcasts a system information block comprising the second information.

[0405] In some embodiments, the system information block includes, but is not limited to, a MIB.

[0406] In some embodiments, the system information block may also be a system information block on demand of the terminal.

[0407] In some embodiments, the second information may be carried in a reference time information element (IE).

[0408] In some embodiments, the reference time is used for the terminal to send the first information to the first network node.

[0409] In some embodiments, the first information indicates at least one of the following:

[0410] Data burst arrival time;

[0411] The jitter range of data arrival;

[0412] Data arrival cycle.

[0413] The embodiment of the present disclosure provides a method for a terminal to report service information or traffic information (Traffic info) auxiliary information, which may specifically include: the terminal reports traffic information (Traffic info) auxiliary information to a base station through user assistance information (User Assistance Information, UAI).

[0414] In some embodiments, the traffic information (Traffic info) auxiliary information carried by the UAI may include information about the burst arrival time (BAT), the jitter range, and the data transmission period. The service to which the data relates may be a specific service. The specific service may include, but is not limited to, an Extended Reality (XR) service. The service to which the data relates may also be a service of a specific priority.

[0415] Based on the UL jitter reported by the terminal, the terminal obtains a reference time for determining the auxiliary information of the traffic information from the base station node.

[0416] As an embodiment, the terminal obtains the system frame number (SFN), subframe number and / or time slot of the base station node from the base station node to determine the traffic information auxiliary information reference time and / or reference clock.

[0417] As an embodiment, the terminal obtains the system frame number (SFN) and subframe number of the base station node from the base station node, which can be obtained from the master information block (MIB) of the base station node.

[0418] As an embodiment, the base station node may be a base station node of a primary cell (PCell).

[0419] As an embodiment, the base station node may be a node of a primary secondary cell (PSCell).

[0420] As an embodiment, the base station node may be a node of a cell designated by the network.

[0421] As an embodiment: in the case where the base station node can be a cell designated by the network, if the network does not designate a cell, it can be a cell agreed upon by the protocol. The cell agreed upon by the protocol can be, for example, a primary cell and / or a secondary cell, but is not limited to the primary cell and / or the primary and secondary cells.

[0422] When the terminal reports the traffic information auxiliary information, it can be reported to the MN and / or SN node.

[0423] As an embodiment, the terminal reports to the SN node. For example, if the SN is configured with SRB3, the terminal can report to the SN via SRB3. If the SN is not configured with SRB3, the terminal can report to the MN node via SRB1.

[0424] As an embodiment, if the terminal only reports the traffic information auxiliary information to the MN, the reference time information of the traffic information auxiliary information is the network element node of the MN. The cell corresponding to the MN is the primary cell (Pcell).

[0425] When the terminal reports traffic information auxiliary information, part of it can be reported to the MN node and part of it can be reported to the SN node.

[0426] In one embodiment, the terminal may report BAT only to the SN node or the MN node. If the SN is configured with SRB3, BAT may be reported to the SN via SRB3. If the SN is not configured with SRB3, BAT may be reported to the MN node via SRB1. In other embodiments, the period and jitter range information may be reported only to the MN node.

[0427] In this way, period and jitter range information can be reported solely to the MN's time reference, rather than to both nodes simultaneously. BAT information, however, is reported separately to each node, taking into account the different timings of the MN and SN. This eliminates the need to report all service-assisted information to both nodes, saving signaling overhead.

[0428] If the terminal can report traffic information and auxiliary information to the SN node, then its reference time is the SN network node.

[0429] As an embodiment, the base station node serving as the SN of the reference time may be a PSCell.

[0430] As an embodiment: if the terminal reports traffic information auxiliary information to the MN and SN nodes: the reference times are PCell and PSCell respectively.

[0431] In some embodiments, the terminal may send a UAI carrying the aforementioned traffic information (Traffic info) auxiliary information to the MN or SN. The cell of the terminal may be divided into multiple cell groups. These cell groups may include a master cell group (MCG) and a secondary cell group (SCG). For each cell group, there is a corresponding prohibition timer for UAI transmission. For example, a prohibition timer for reporting traffic information UAI is maintained for each MCG and SCG.

[0432] While the inhibit timer is running, the terminal does not send UAI to the network node associated with the inhibit timer.

[0433] When the prohibit timer times out, the terminal may send the UAI to the network node associated with the prohibit timer.

[0434] In the case of dual connection release of the terminal, if the terminal is configured with SCG, the terminal will stop the prohibition timer associated with the SCG.

[0435] The primary cell group includes at least a primary cell. In some cases, the primary cell group may also include one or more secondary cells.

[0436] The secondary cell group includes one or more secondary cells.

[0437] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

[0438] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network node (e.g., an access network device or a core network device) in any of the above methods.

In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions.

Taking a field programmable gate array (FPGA) as an example, it can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by configuring the configuration file, thereby realizing the functions of some or all of the above units or modules. All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

The logical relationship of the above-mentioned hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document to implement the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
