Information transmission method, device, electronic device and storage medium

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202311811336.1 filed in China on December 26, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the field of communication technology, and in particular to an information transmission method, device, electronic device, and storage medium. Background Art

[0004] New Radio Dual Connectivity (NR-DC) is a key technology in 5G networks. It provides higher data rates and a better user experience by enabling the collaboration of two 5G cells. Selective cell group activation is a key feature of NR-DC that improves the efficiency and performance of handovers between user equipment (UE) and cells without requiring Radio Resource Control (RRC) reconfiguration.

[0005] In the selective cell group activation mechanism, the network will pre-configure multiple primary and secondary cells (PSCell) configurations for the UE in advance and set the corresponding execution conditions. These PSCells can have the same or different execution conditions, and the UE will select the appropriate PSCell for connection by evaluating the execution conditions. After the UE selects a PSCell, it will not release the stored configuration, but will continue to evaluate the execution conditions and select the next suitable PSCell. During this process, the network does not need to perform RRC reconfiguration, and can implement cell group switching without affecting UE communication, thereby improving the capacity and performance of the system. The selective cell group activation of NR-DC is also called continuity CPAC, that is, continuity conditional primary and secondary cell addition and / or change (Subsequent Conditional PSCell Addition / Change, S-CPAC).

[0006] As can be seen, for S-CPAC, the network needs to configure multiple PSCells for the UE, and these cells need to reserve corresponding resources for the UE. However, in reality, the UE's movement trajectory changes dynamically, and some candidate PSCells may not be accessed by the UE during the S-CPAC process, but corresponding resources must still be reserved for the UE, resulting in a certain amount of resource waste.

[0039] In order to make the purpose, technical solutions and advantages of the present disclosure more apparent, the following will describe in detail exemplary embodiments of the present disclosure with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited to the exemplary embodiments described herein.

[0040] First, an application scenario according to an embodiment of the present disclosure is summarized with reference to FIG. 1 .

[0041] FIG1 is a schematic diagram illustrating an application scenario of the information transmission method according to an embodiment of the present disclosure. As shown in FIG1 , the application scenario includes at least: a network-side device (e.g., network-side device 10, network-side device 11, network-side device 12, network-side device 13, ..., network-side device 1N) and a terminal 20.

[0042] Among them, the network side device (for example, network side device 10, network side device 11, network side device 12, network side device 13, ..., network side device 1N) can be a device for communicating with the terminal, and the network device can be a base transceiver station (BTS) in a global system for mobile communications (GSM) or a code division multiple access (CDMA) communication system, a base station (nodeB, NB) in a wideband code division multiple access (WCDMA) communication system, an evolved base station (eNB or eNodeB) in a long term evolution (LTE) communication system, a next generation evolved node B (ng-eNB) in a new radio (NR) communication system, a next generation node B (gNB) in an NR communication system, or a base station in a future communication system or other devices in a core network (CN), such as an access and mobility management function (AMF), a user plane function ( In addition, the network device may also be an access point (AP) in a wireless local area network (WLAN), a relay station, a network device in a future evolved public land mobile network (PLMN) network, or a network device in a non-terrestrial network (NTN) network. As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiment of the present disclosure, only the base station in the NR system is taken as an example, but the specific type and specific number of the base station are not limited.

[0043] The terminal 20 may refer to a user equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a wireless terminal, a user agent, or a user device. Optionally, the terminal 20 may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal in a fifth generation mobile communication system (5GS), or a terminal in a future evolved network, etc. It should be noted that the specific type and specific number of the terminal 20 are not limited in the embodiments of the present disclosure.

[0044] Furthermore, the terminal 20 can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can be deployed on the water surface (such as ships, etc.); it can also be deployed in the air (such as airplanes, balloons and satellites, etc.).

[0045] Furthermore, the terminal 20 may be a mobile phone, 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, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or a wireless terminal device in a smart home, etc.

[0046] Figure 2 is a schematic diagram illustrating NR-DC in a 5G network according to an embodiment of the present disclosure. As shown in Figure 2, in a 5G network, New Radio Dual Connectivity (NR-DC) allows a UE to simultaneously connect to two 5G base stations (using network-side device 10 and network-side device 11 as examples in Figure 2), thereby achieving higher data transmission rates and better network performance.

[0047] In NR-DC, there are Master Nodes (MN) and Secondary Nodes (SN). The Master Node can be understood as the main base station (such as the network-side device 10 in Figure 2), which is responsible for providing the main services and coverage. Specifically, it is responsible for establishing a connection with the UE and handling data transmission and communication. The Secondary Node can be understood as an affiliated base station (such as the network-side device 11 in Figure 2), which collaborates with the Master Node to provide additional capacity, coverage or specific business support. The Secondary Node can increase network capacity, improve data transmission rate, and provide users with a better communication experience by connecting to the Master Node. This can effectively utilize multiple base station resources and provide better network performance and user experience.

[0048] In addition, the UE can also access only a single 5G base station. This situation can be simply referred to as the UE being in a single connection (standalone, SA) state. The UE can perform the conditional primary and secondary cell addition and / or change (Conditional PSCell Addition / Change, CPA / CPC) process to add and / or change the appropriate PSCell.

[0049] When a UE initiates a connection, it first connects to the primary node and then adds secondary nodes as needed. Both the primary and secondary nodes can internally support multiple carriers for carrier aggregation (CA), bundling multiple carriers to increase transmission rates. A cell group is the basic unit for CA implementation. The primary node corresponds to the Master Cell Group (MCG), while the secondary nodes correspond to the Secondary Cell Group (SCG).

[0050] Under an MCG, there may be multiple cells. The cell used to initiate initial access is called the primary cell (PCell), which can be understood as the most "important" cell in the MCG, such as cell M1 in Figure 2. Other cells under the MCG are called secondary cells (SCells), such as cells M2, ..., and Mn in Figure 2. The PCell and SCell in the MCG are combined using the Carrier Access Control (CA) technology.

[0051] Similarly, the cell that initiates initial access within an SCG is called the Primary Secondary Cell (PScell). The PSCell can be understood as the most "important" cell in the SCG, such as cell S1 in Figure 2. Other cells within the SCG are called Secondary Cells (SCells), such as cells S2, ..., and Si in Figure 2. The PSCell and SCell within the SCG are also combined using Carrier Access Control (CA) technology.

[0052] The selective cell group activation mechanism is an important concept in NR-DC. It can be used to dynamically select which cell groups to activate in dual connectivity to achieve higher data rates and a better user experience. Specifically, the selective cell group activation mechanism improves the efficiency and performance of handovers between UEs and cells without the need for RRC reconfiguration.

[0053] In the selective cell group activation mechanism, the network pre-configures multiple PSCell configurations for the UE and sets the corresponding execution conditions. These PSCell configurations can have the same or different execution conditions. The UE selects the appropriate PSCell for connection by evaluating the execution conditions. The selection process is similar to the previous CPA / CPC, but it can be executed continuously. No RRC reconfiguration is expected during this process.

[0054] Selective cell group activation in NR-DC is also called continuous CPAC, or S-CPAC. The configuration optimization method for S-CPAC is described in further detail below with reference to FIG3 .

[0055] Figure 3 is a flowchart illustrating an overall information transmission method according to an embodiment of the present disclosure. As described above, the technical solutions proposed in this disclosure are primarily implemented by terminals and network-side devices. As shown in Figure 3, the overall process for S-CPAC configuration optimization may include at least the following steps.

[0056] 1. The network-side device configures the terminal to record S-CPAC related information. The S-CPAC related information may include at least one or more of the following.

[0057] 3-1.1 Identification of the service and / or candidate primary and secondary cells accessed by the terminal

[0058] As described above, in the selective cell group activation mechanism, the network pre-configures multiple PSCells for the UE to activate. These pre-configured PSCells are referred to as candidate primary and secondary cells. Among these candidate primary and secondary cells, the one that the UE actually accesses is referred to as the serving primary and secondary cell, collectively referred to as serving and / or candidate primary and secondary cells.

[0059] The UE may record the identifiers of the accessed services and / or candidate primary and secondary cells to form a list.

[0060] In one embodiment of the present disclosure, the list may be recorded in the order of access, such as {PSCell1, PSCell2, PSCell3, ...}. If the same PSCell is accessed repeatedly, the PSCell ID will be recorded multiple times based on the actual access situation, such as {PSCell1, PSCell2, PSCell3, ..., PSCell1, ...}.

[0061] In another embodiment of the present disclosure, the list may be in the form of recording in the order of access, but each PSCell ID is recorded only once, and each PSCell ID is provided with an additional indication showing the number of times the cell has been accessed, for example {PSCell1(2), PSCell2, PSCell3, ...}, where (2) indicates access to PSCell1 2 times, and the default access without additional indication is 1 time.

[0062] 3-1.2 Time when the terminal accesses the serving and / or candidate primary and secondary cells

[0063] The time of accessing a serving and / or candidate primary and secondary cell may include at least: the start time, end time, or residence time in the cell. The network-side device may optimize resources based on the residence time of the UE in each serving and / or candidate primary and secondary cell. For example, more resources may be allocated to candidate primary and secondary cells with a long historical residence time, and fewer resources may be allocated to candidate primary and secondary cells with a short historical residence time, to avoid resource shortage and / or waste.

[0064] 3-1.3 Measurement Results of Serving and / or Candidate Primary and Secondary Cells

[0065] The measurement results of the serving and / or candidate primary and secondary cells include at least the cell quality of the serving cell and / or other candidate primary and secondary cells, such as Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ). Cell quality generally refers to an assessment of the wireless signal coverage and transmission quality within the cell.

[0066] 3-1.4 Execution Conditions for Serving and / or Candidate Primary and Secondary Cells

[0067] The execution condition can be understood as one or more triggering events. When the UE evaluates that the candidate primary and secondary cells meet the triggering events, the PSCell is added or changed.

[0068] The network can comprehensively judge whether the execution condition settings are reasonable based on the service accessed by the terminal and / or the execution conditions of the candidate primary and secondary cells, and / or the cell quality, and then optimize the thresholds of each trigger event in the execution condition to make it more reasonable.

[0069] 3-1.5 Location of the service and / or candidate primary and secondary cells accessed by the terminal

[0070] The UE's access location can be used in conjunction with other information. For example, the network can use the terminal's location and cell quality to determine the most appropriate cell for the terminal to access, and further optimize the configuration of execution conditions. Furthermore, the network can analyze and optimize network coverage and performance based on the signal quality received by the UE at different access locations.

[0071] 3-1.6 SK-counter for used and / or unused keys in the serving and / or candidate primary and secondary cells accessed by the terminal

[0072] In one embodiment of the present disclosure, for example, multiple SK-counters are configured for candidate primary and secondary cells {PSCell 1, PSCell 2, PSCell 3} of SN1, with the SK-counter list being {1, 2, 3, 4}. The UE records the SK-counters based on actual usage. When PSCell 1 accesses, SK-counter 1 is used; when PSCell 2 accesses, SK-counter 2 is used. SK-counters {3, 4} are not used until the process completes.

[0073] This means that too many SK-counters are configured for SN1, resulting in a waste of SK-counters {3, 4}. The number of configured SK-counters can be optimized based on the number of actually used and / or unused SK-counters.

[0074] 3-1.7S-CPAC Configuration

[0075] The configuration of S-CPAC may include at least one or more of the following: configuration of serving and / or candidate primary and secondary cells, reference configuration, configured SK-counter list, execution conditions, etc.

[0076] Among them, the S-CPAC configuration can be the configuration initially sent down by the network side device, or it can be the latest configuration (for example, the network side device updates the configuration to the UE, and the UE only needs to save the latest configuration), or it can be configuration information containing intermediate updates, and further can include PCell ID and / or PSCell ID, time and other information when receiving the updated configuration information.

[0077] The configuration information updated in the middle is recorded and can be used to send it to the corresponding SN for subsequent configuration optimization, minimizing reconfiguration during the UE's S-CPAC execution process and reducing signaling load.

[0078] These configurations are sent by the network-side device to the UE. The UE needs to record them and report them to the network-side device later. This is mainly because after the UE completes this process, the network-side device will release these configurations, or after the UE releases the connection with the network-side device, the network-side device will delete the UE context, and these configurations are also deleted. The UE report may have a certain lag, so the previous configuration needs to be recorded and reported to the network-side device later for subsequent configuration optimization.

[0079] 3-1.8 Status of the service and / or candidate primary and secondary cells accessed by the terminal

[0080] The terminal status here may include dual connectivity (DC) and single connectivity (standalone, SA).

[0081] Specifically, when the terminal state is DC, the network-side device can optimize the execution conditions of CPC of the corresponding candidate primary and secondary cells based on the relevant information recorded and subsequently reported by the UE (such as measured cell quality and execution conditions);

[0082] When the terminal state is SA, the network side device can optimize the execution conditions of CPA of the corresponding candidate primary and secondary cells based on relevant information recorded and subsequently reported by the UE (such as measured cell quality and execution conditions).

[0083] 3-1.9 Reasons and / or Time for S-CPAC Configuration Release

[0084] The release reason may be, for example, receiving a network instruction, a PCell change, an execution failure, an SCG failure, etc. The network side device collects the configuration release reasons and can use them to optimize the resource reservation time.

[0085] 3-1.10 Information on Failed CPAC Execution

[0086] Information on S-CPAC failure, such as PSCell measurement results, can be used by subsequent network-side devices to analyze the cause of the S-CPAC failure.

[0087] Optionally, the S-CPAC related information recorded by the terminal can also be preset. For example, the protocol stipulates which S-CPAC information the terminal needs to record, and there is no need for dynamic configuration of the network-side equipment. The network can also configure the trigger conditions and / or events for the terminal to record S-CPAC related information. When the trigger conditions and / or events are met, the terminal records the relevant information. The trigger conditions and / or events include but are not limited to: at what time or time period to record (such as recording during the entire S-CPAC process), at what location to record, when there are candidate primary and secondary cells that are not connected, record and report when there are unused SK-counters, and so on.

[0088] 2. The terminal records S-CPAC related information. As described above, step 1 describes which related information the network device requires the UE to record (such as one or more of the above 3-1.1 to 3-1.10, which are not repeated here, and similarly, the subsequent steps 2-5 are not repeated here). This step is for the UE to record this related information.

[0089] 3. The terminal notifies the network device that it has recorded or has available S-CPAC related information. As described above, in step 2, the UE performs recording of S-CPAC related information. In this step, after the UE completes the recording, it sends a message to the network device to inform it that the recording is complete.

[0090] 4. The network device requests the terminal to report all or part of the S-CPAC related information. As mentioned above, in step 3, the UE notifies the network device that its recording is complete. In this step, after the network device learns of this, it will send a message to the UE when it needs to instruct and / or request the UE to report this information.

[0091] Among them, steps 3 and 4 are optional. The network-side device can allow the terminal to report all or part of the recorded relevant information based on its own preferences, or selectively allow certain terminals to report relevant information and certain terminals not to report relevant information. These methods can reduce the signaling load of the air interface. In addition, the network can also configure some trigger conditions and / or events. When the trigger conditions and / or events are met, the terminal reports the recorded S-CPAC related information; it can also allow the terminal to report S-CPAC related information through preset rules (such as protocol regulations, etc.). Trigger conditions and / or events include but are not limited to: reporting time or time period, reporting location, reporting after the S-CPAC process is completed, reporting when there are candidate primary and secondary cells that have not been connected, reporting when there are unused SK-counters, etc.

[0092] 5. The terminal reports S-CPAC related information. As described above, in step 4, the network-side device instructs and / or requests the UE to report the S-CPAC related information it has recorded. This step is performed by the UE.

[0093] Specifically, the UE may report the above information by reporting through a random access report or reporting through a newly defined message. For example, the UE may report the above information based on the following situations.

[0094] Case 1: The network side device requests the UE to report;

[0095] Case 2: UE proactively reports;

[0096] Case 3: The UE notifies the network device of the above information and then requests the network device to send it; a field is introduced to indicate the existence of the S-CPAC record;

[0097] Case 4: The network-side device pre-configures some trigger conditions / events for the UE, or the protocol specifies some trigger conditions / events, such as the reporting time interval, reporting location, reporting after the S-CPAC process is completed, reporting when there are no connected candidate primary and secondary cells, reporting when there are unused SK-counters, etc. It should be noted that the trigger conditions proposed in this disclosure for triggering the UE to report the above information are only exemplary and do not constitute a specific limitation.

[0098] 6. The network-side device optimizes the S-CPAC configuration. The specific implementation of this step depends primarily on the network implementation. As described above, in step 5, the UE has uploaded S-CPAC-related information. In this step, the network-side device optimizes the S-CPAC configuration based on this information after receiving it. The S-CPAC configuration optimization may include at least one or more of the following:

[0099] (1) Optimize the list of candidate primary and secondary cells based on the service accessed by the terminal and / or the identifier of the candidate primary and secondary cells. As described above, 3-1.1 includes the identifier of the accessed service and / or the candidate primary and secondary cells. The network-side device can analyze which candidate primary and secondary cells are not accessed by the UE or have not been accessed by the UE for a long time. The network-side device can consider not configuring the candidate primary and secondary cells for the UE during subsequent pre-configuration, that is, optimizing the list of candidate primary and secondary cells to conserve the resources of the candidate primary and secondary cells.

[0100] (2) Optimizing execution conditions based on measurement results and / or execution conditions. As described above, 3-1.3 includes the measurement results of the accessed serving primary and secondary cells and the measurement results of other candidate primary and secondary cells, and 3-1.4 includes the execution conditions of the serving and / or candidate primary and secondary cells. The network-side device can determine whether the configuration of the execution conditions is reasonable based on the above information, and then adjust the thresholds of each trigger event in the execution conditions to optimize the thresholds to make them more reasonable.

[0101] (3) Optimizing the value and / or number of SK-counters reserved for candidate primary and secondary cells based on the SK-counters used and / or unused by the service and / or candidate primary and secondary cells accessed by the terminal. As mentioned above, 3-1.6 includes the SK-counters used and / or unused by the service and / or candidate primary and secondary cells. The network-side device can adjust the number or specific value of SK-counters subsequently reserved for candidate primary and secondary cells / SNs based on this information.

[0102] In one embodiment of the present disclosure, for example, the network side device reserves 5 SK-counters for SN1, but the actual UE only uses 2. The number of reserved SK-counters can be reduced later to avoid wasting resources.

[0103] In another embodiment of the present disclosure, for example, if some candidate primary and secondary cells / SNs have been accessed multiple times by the UE and no SK-counters are available, the network device may configure more SK-counters for the candidate primary and secondary cells / SNs. For example, if the network device configures the SK-counter list {1, 2, 3} for the candidate primary and secondary cells {PSCell1, PSCell2, PSCell3} of SN1, and all three SK-counters have been used, the network device may subsequently configure more SK-counters for SN1.

[0104] (4) Optimizing the reservation time of candidate primary and secondary cell resources based on the time the terminal accesses the service and / or candidate primary and secondary cells. As described above, 3-1.2 includes the time the terminal accesses the service and / or candidate primary and secondary cells. The network-side device can optimize the reservation time of candidate primary and secondary cell resources based on this information. For example, more resources may be allocated to candidate primary and secondary cells with a long historical residence time, and fewer resources may be allocated to candidate primary and secondary cells with a short historical residence time, to avoid resource shortage and / or waste.

[0105] (5) Optimize the coverage of candidate primary and secondary cells based on location and / or measurement results. As described above, 3-1.3 includes the measurement results of the accessed serving primary and secondary cells, the measurement results of other candidate primary and secondary cells, and 3-1.4 includes the location of the serving and / or candidate primary and secondary cells accessed by the terminal. The network-side device can analyze the network coverage effect and performance based on the above information and optimize it. For example, if the measurement results at a certain location are relatively poor, then consider increasing the coverage of the candidate primary and secondary cells at that location.
