[0001] Cross-reference to related applications

[0002] The present disclosure is based on and claims priority from Chinese patent application 2024108498733 filed on June 27, 2024, the disclosure of which is incorporated herein in its entirety by reference. TECHNICAL FIELD

[0003] Embodiments of the present disclosure relate to the field of communication, in particular to a resource configuration method based on carrier aggregation service. BACKGROUND

[0004] Since new radio communication technology (NR) carrier aggregation involves cross-site and cross-carrier scenarios, it is very difficult to implement a dynamic codebook. Currently, the industry usually configures Sounding Reference Signal (SRS) periodic resources, Channel State Information (CSI) resources, etc. when adding a carrier, and the Physical Uplink Control Channel (PUCCH) uses a semi-static codebook. When the secondary carrier is activated, it is directly activated through a Medium Access Control Control Element (MAC CE). The PUCCH scheduling notification format 3 PUCCH AN format 3 resource is statically allocated for each UE, so it is easy to cause resource constraints; similarly, the SRS periodic resource is also easy to be limited by capacity. However, in fact, most users in the actual network are in the state of adding a secondary carrier but not activating it. For these users, there is no need to offload data to the secondary carrier, and there is no need to allocate wireless resources to the secondary carrier. Directly activating the previously configured resources causes resource waste.

[0005] How to reasonably allocate resources based on carrier aggregation has not yet been effectively solved. SUMMARY

[0006] Embodiments of the present disclosure provide a resource configuration method based on carrier aggregation service, to at least solve the problem of resource waste caused by directly activating previously configured resources when activating a secondary carrier after configuring resources for the secondary carrier in the related art.

[0019] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings and in conjunction with embodiments.

[0020] It should be noted that the terms "first", "second", and the like in the specification and claims of the present disclosure and the above-described drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence.

[0021] The method embodiments provided in the embodiments of the present disclosure can be executed in a mobile terminal, a computer terminal or similar computing device. Taking an example of running on a mobile terminal, FIG. 1 is a hardware structure block diagram of a mobile terminal of a resource configuration method based on carrier aggregation service according to an embodiment of the present disclosure. As shown in FIG. 1, the mobile terminal can include one or more (only one is shown in FIG. 1) processors 102 (the processor 102 can include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal can further include a transmission device 106 for communication function and an input and output device 108. Those skilled in the art can understand that the structure shown in FIG. 1 is only schematic, which does not limit the structure of the mobile terminal. For example, the mobile terminal can further include more or less components than those shown in FIG. 1, or have a different configuration from that shown in FIG. 1.

[0022] The memory 104 can be used to store computer programs, for example, software programs of application software and modules, such as a computer program corresponding to the resource configuration method based on carrier aggregation service in the embodiments of the present disclosure. The processor 102 executes various functional applications and data processing by running the computer programs stored in the memory 104, that is, implements the above method. The memory 104 can include a high-speed random access memory, and can further include a non-volatile memory, such as one or more magnetic storage devices, flash memories, or other non-volatile solid-state memories. In some examples, the memory 104 can further include a memory remotely arranged with respect to the processor 102, which can be connected to the mobile terminal through a network. Examples of the above network include but are not limited to the Internet, an intranet, a local area network, a mobile communication network and a combination thereof.

[0023] The transmission device 106 is used to receive or send data via a network. Specific examples of the above network can include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, NIC for short), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (Radio Frequency, RF for short) module, which is used to communicate with the Internet in a wireless manner.

[0024] Figure 2 is a network architecture diagram of carrier aggregation according to an embodiment of the present disclosure, and the embodiment of the present disclosure can run on the network architecture shown in Figure 2, as shown in Figure 2, 5G core network (5th Generation Core Network, 5GC), primary carrier (Primary Cell, PCell), primary secondary carrier (Primary Secondary Cell, PSCell), secondary carrier (Secondary Cell, SCell) and user equipment (User Equipment, UE), wherein the interaction and functions between 5GC, PCell, PSCell, SCell and UE can be as follows:

[0025] 5GC: 5G core network is the central component of 5G network, responsible for processing user data transmission, managing user identity, charging and network configuration, etc. 5GC communicates with UE (user equipment) to realize user data transmission and management.

[0026] PCell: The primary carrier is the main channel for UE to connect to the network, responsible for carrying the main control information and data transmission. PCell usually has high priority to ensure the stability of critical communication when the network load is high.

[0027] PSCell: The primary secondary carrier is an auxiliary carrier associated with the PCell, which can provide additional bandwidth and capacity based on the PCell. PSCell is mainly used to carry UE's data traffic to improve data transmission rate. PSCell and PCell have close coordination to ensure the stability and efficiency of data transmission.

[0028] SCell: The secondary carrier is another auxiliary carrier associated with the primary carrier PCell or the primary secondary carrier PSCell. SCell can be used to expand bandwidth, improve data transmission rate or achieve load balancing. SCell works with PCell or PSCell through specific protocols.

[0029] UE: User equipment is a terminal device connected to the network, such as smartphones, tablets, etc. UE realizes data reception and transmission through interaction with PCell, PSCell and SCell.

[0030] As an example, UE can establish a connection with 5GC through PCell to realize basic communication functions.

[0031] When the network needs to expand bandwidth or improve data transmission rate, UE can work with PCell through PSCell or SCell. For example, UE can receive data through PSCell, or achieve load balancing through SCell.

[0032] Information exchange between PCell, PSCell and SCell can be carried out through a specific protocol (such as Xn interface) to ensure stability and efficiency of data transmission.

[0033] The 5GC can dynamically adjust the configuration of PCell, PSCell and SCell according to network conditions and the needs of the UE to achieve the best network performance.

[0034] A resource configuration method based on carrier aggregation service running on the above mobile terminal or network architecture is provided in the embodiment. FIG. 3 is a flowchart of resource configuration based on carrier aggregation service according to the embodiment of the disclosure. As shown in FIG. 3, the flow includes the following steps:

[0035] Step S301, determine the configuration state of the secondary carrier of the user equipment, and obtain the current state information of the cell and the current carrier resource configuration information.

[0036] In the embodiment of the disclosure, the configuration state of the secondary carrier of the user equipment can include a configured state or an unconfigured state. The configuration state of the secondary carrier of the user equipment can be determined first, and then the current state information of the cell and the current carrier resource configuration information can be obtained.

[0037] In an exemplary embodiment, the determination of the configuration state of the secondary carrier of the user equipment and the acquisition of the current state information of the cell and the current carrier resource configuration information include:

[0038] When the configuration state of the secondary carrier is determined to be configured, the current state information of the cell and the current carrier resource configuration information are obtained.

[0039] When the configuration state of the secondary carrier is determined to be unconfigured, the current state information of the cell is obtained, and resources are configured for the carrier according to the current state information of the cell to generate the current carrier resource configuration information.

[0040] For example, when the configuration state of the secondary carrier is configured, the current state information of the cell and the current carrier resource configuration information can be obtained directly. When the configuration state of the secondary carrier is unconfigured, the current state information of the cell can be obtained, and resources can be configured for the carrier according to the current state information of the cell to generate the current carrier resource configuration information.

[0041] In an exemplary embodiment, the current state information of the cell is used to indicate at least one of the following information: cell load state, resource consumption, cell coverage intensity, cell traffic size, interference level, and cell user density.

[0042] As an example, the cell current state information can indicate cell load state, resource consumption, or cell coverage intensity, cell traffic size, interference level, cell user density, etc. For example, the cell coverage intensity can be classified as weak coverage and medium-strong coverage scenarios, etc.; the cell traffic size can be classified as dense and sparse traffic, or small bandwidth or large bandwidth, etc.; the interference level can be classified as strong interference scenario and weak interference scenario, etc.; the cell user density can be classified as dense urban and suburban scenarios, etc.

[0043] As an example, the carrier resource configuration information can be used to indicate resource configuration of the secondary carrier, for example, the secondary carrier is currently configured with PUCCH resource or SRS resource or CSI resource, etc.

[0044] The embodiments of the present disclosure take the cell current state information indicating the cell load state or resource consumption as an example for illustration.

[0045] Exemplarily, in a wireless network, when it is determined that a user equipment (UE) needs to add a secondary carrier, the load state or resource consumption of the cell where the UE currently locates can be counted.

[0046] As an example, data samples of different UEs in each cell in the wireless network can be collected in real time, and different states of each cell and each UE are determined, and then resources can be configured for which users according to the different states of each cell and each UE. Thus, higher resource configuration efficiency is achieved, and the purpose of intelligent network operation is achieved.

[0047] As an example, in the carrier aggregation service process, the resource consumption of the secondary carrier can be counted in real time, and the terminal to be added and activated is configured with appropriate resources, so as to more reasonably optimize the allocation of wireless resources and improve system performance.

[0048] In an exemplary embodiment, the cell current state information is used to indicate the cell load state, and the cell current state information includes at least one of the following information: the number of radio resource control (RRC) connection users, the number of cell carrier aggregation (CA) added users, the number of cell CA activated users, the physical resource block (PRB) utilization rate, the control channel element (CCE) allocation failure rate, the single board processor utilization rate, and the cell throughput rate.

[0049] In an exemplary embodiment, the cell current status information is used to indicate resource consumption, and the cell current status information comprises at least one of the following information: PUCCH AN FORMAT3 resource utilization or resource consumption, PUCCH AN FORMAT3 resource allocation failure rate or number of allocation failures, number of users or queue length of PUCCH AN FORMAT3 resource application queue, SRS periodic resource utilization, SRS short period preemption failure rate, CSI resource allocation failure rate.

[0050] In an exemplary embodiment, the cell current status information is obtained, and resources are configured for the carrier according to the cell current status information, comprising:

[0051] According to the cell current status information and a preset first status information threshold, a cell current status level is determined; the cell current status level comprises a first status level and a second status level.

[0052] Resources are configured for the carrier according to the cell current status level.

[0053] Exemplarily, the cell current status level can be determined according to the cell current status information and the preset first status information threshold, and resources can be configured for the carrier according to the cell current status level.

[0054] For example, when the cell current status information is lower than the preset first status information threshold, the cell current status level is determined as the first status level, and when the cell current status information is higher than the preset first status information threshold, the cell current status level is determined as the second status level.

[0055] For example, the first status level can be used to indicate that the cell is in a low load or low resource consumption state, and the second status level can be used to indicate that the cell is in a medium load or medium resource consumption state.

[0056] In an exemplary embodiment, the resources are configured for the carrier according to the cell current status level, comprising:

[0057] When the cell current status level is the first status level, a PUCCH semi-static codebook is configured for a primary secondary carrier, or a CSI resource is configured for a secondary carrier, or an SRS short period resource is configured for a secondary carrier.

[0058] The first status level is a status level when the cell current status information is lower than the preset first status information threshold.

[0059] Exemplarily, if the configuration state of the secondary carrier is not configured, the current state information of the cell can be acquired, and the resource of the carrier is configured according to the current state information of the cell, and the current carrier resource configuration information is generated.

[0060] As an example, in the case that the current state level of the cell is the first state level, that is, if the cell is judged to be in a low load or low resource consumption state, the secondary carrier and the radio resource can be directly configured, wherein the radio resource can include at least one of the following: PUCCH semi-static codebook, SRS short period resource, CSI resource, etc.

[0061] In an exemplary embodiment, the resource of the carrier is configured according to the current state level of the cell, including:

[0062] In the case that the current state level of the cell is the second state level, the PUCCH dynamic codebook of the secondary carrier is configured, or the CSI resource is not configured, or the SRS aperiodic resource of the secondary carrier is configured.

[0063] The second state level is the state level when the current state information of the cell is higher than the preset first state information threshold.

[0064] As an example, in the case that the current state level of the cell is the second state level, that is, if the cell is judged to be in a medium load or medium resource consumption state, when the UE configures the secondary carrier, the PUCCH dynamic codebook, SRS aperiodic resource, and CSI resource of the secondary carrier can be configured.

[0065] In step S302, according to the current state information of the cell and the current carrier resource configuration information, the carrier resource is reconfigured when the secondary carrier is activated.

[0066] Exemplarily, when the secondary carrier is activated, the resource of the secondary carrier can be reconfigured according to the current state information of the cell and the current carrier resource configuration information.

[0067] As an example, the resource can include but is not limited to PUCCH resource, SRS resource, CSI resource, etc.

[0068] As an example, at the time of RRC reconfiguration of the resource, for the PUCCH resource, SRS resource, and CSI resource, any one of them can be selected, any two of them can be selected, three of them can be selected, and other possible options can be added, which are not limited by the embodiments of the present disclosure.

[0069] In an exemplary embodiment, the resource of the carrier is configured according to the current state level of the cell, including:

[0070] in a case that the current carrier resource configuration information is PUCCH dynamic codebook configured for the secondary carrier, reconfiguring the PUCCH dynamic codebook as PUCCH semi-static codebook when the secondary carrier is activated;

[0071] in a case that the current carrier resource configuration information is aperiodic SRS resource configured for the secondary carrier, reconfiguring the aperiodic SRS resource of the secondary carrier as SRS short period resource when the secondary carrier is activated;

[0072] in a case that the current carrier resource configuration information is no CSI resource configured, configuring carrier resource with no CSI resource and reconfiguring CSI resource when the secondary carrier is activated.

[0073] As an example, when the cell state level is the first state level, i.e., the cell state is low load or low resource consumption state, if the current secondary carrier configuration of the user is PUCCH dynamic codebook, the PUCCH dynamic codebook can be reconfigured as semi-static codebook when the secondary carrier is activated; or in a case that the current carrier resource configuration information is aperiodic SRS resource configured for the secondary carrier, the aperiodic SRS resource of the secondary carrier is reconfigured as SRS short period resource when the secondary carrier is activated; or in a case that the current carrier resource configuration information is no CSI resource configured, the carrier resource with no CSI resource is configured and CSI resource is reconfigured when the secondary carrier is activated.

[0074] In an exemplary embodiment, the method further comprises:

[0075] determining that the cell state level is the first state level, and the current carrier resource configuration information is PUCCH semi-static codebook, SRS short period resource or CSI resource configured for the secondary carrier, and activating the secondary carrier.

[0076] As an example, when the cell state level is the first state level, i.e., the cell state is low load or low resource consumption state, if the current secondary carrier configuration of the user is PUCCH semi-static codebook or SRS short period resource or CSI resource, the secondary carrier can be directly activated.

[0077] In an exemplary embodiment, the reconfiguring carrier resource when the secondary carrier is activated according to the current cell state level and the current carrier resource configuration information comprises:

[0078] in a case that the current carrier resource configuration information is PUCCH dynamic codebook configured for the secondary carrier, reconfiguring the PUCCH dynamic codebook as PUCCH semi-static codebook when the secondary carrier is activated;

[0079] In a case that the current carrier resource configuration information is that the secondary carrier is configured with a PUCCH dynamic codebook, the PUCCH dynamic codebook is reconfigured as a PUCCH semi-static codebook when the secondary carrier is activated.

[0080] In a case that the current carrier resource configuration information is that the secondary carrier is configured with aperiodic SRS resources, the aperiodic SRS resources of the secondary carrier are reconfigured as SRS short period resources when the secondary carrier is activated.

[0081] In a case that the current carrier resource configuration information is that no CSI resource is configured, CSI resources are reconfigured when the secondary carrier is activated.

[0082] Exemplarily, in a case that the cell state level is the second state level, i.e., the cell state is a medium load or the resource consumption is in a medium state, and the secondary carrier is configured with a PUCCH dynamic codebook, when the secondary carrier needs to be activated, the wireless resources of the secondary carrier can be re-allocated, and the wireless resources can include at least one of the following: PUCCH AN format 3 resources, SRS short period resources, CSI resources, etc.

[0083] As an example, in a case that the current carrier resource configuration information is that the secondary carrier is configured with a PUCCH dynamic codebook, the PUCCH dynamic codebook can be reconfigured as a PUCCH semi-static codebook when the secondary carrier is activated.

[0084] As an example, in a case that the current carrier resource configuration information is that the secondary carrier is configured with aperiodic SRS resources, the aperiodic SRS resources of the secondary carrier can be reconfigured as SRS short period resources when the secondary carrier is activated.

[0085] As an example, in a case that the current carrier resource configuration information is that no CSI resource is configured, CSI resources can be reconfigured for the secondary carrier when the secondary carrier is activated.

[0086] In an exemplary embodiment, the current state level of the cell further includes a third state level; and the method further includes:

[0087] In a case that the current state of the cell is the third state level, and the current carrier resource configuration information is that the secondary carrier is configured with a PUCCH dynamic codebook or no CSI resource, or the secondary carrier is configured with aperiodic SRS resources, the secondary carrier is not activated.

[0088] The third state level is higher than the second state level, and the second state level is higher than the first state level.

[0089] Exemplarily, the current state level of the cell can further include a third state level, which can be a level higher than the second state level.

[0090] As an example, the third state level can be used to indicate that the cell is in a high load or high resource consumption state, and when the UE adds a secondary carrier, a PUCCH dynamic codebook or SRS aperiodic resource strategy can be adopted.

[0091] As an example, in the case where the current carrier resource configuration information is that the secondary carrier is configured with a PUCCH dynamic codebook or no CSI resource, or the secondary carrier is configured with an aperiodic SRS resource, when the secondary carrier needs to be activated, it can be processed according to a high load activation strategy, for example, the secondary carrier is not activated, or it is processed according to a medium load or medium resource consumption state.

[0092] In the embodiments of the present disclosure, by determining the configuration state of the secondary carrier of the user equipment, and obtaining the current state information of the cell and the current carrier resource configuration information, according to the current state information of the cell and the current carrier resource configuration information, when the secondary carrier is activated, the carrier resource is reconfigured, so as to more reasonably optimize the allocation of wireless resources and improve the system performance, and the problem that in the related art, after the secondary carrier is configured with resources, when the secondary carrier needs to be activated, the previously configured resources are directly activated, which causes waste of resources for users who do not need the secondary carrier to offload data.
