Broadcasts and public channels between slices of public private networks cannot be configured differentially. For SLA (Service Level Agreement, service level agreement) in specific private network scenarios, that is to say, solutions in related technologies cannot achieve public Data processing when private networks are divided into cells and spectrum resources are shared cannot achieve physical isolation between public and private networks, nor can data processing be achieved when the above-mentioned public and private networks are integrated.

In traditional mobile communication technology, carriers and physical cells have a one-to-one correspondence, that is, one carrier corresponds to one physical cell; in the field of 5G mobile communication technology, Multi-SSB (Multiple Synchronization Signal/PBCH Block, multi-synchronization/physical The concept of broadcast channel block); in the Multi-SSB scenario, there can be multiple cells on one carrier; the embodiment of this application adopts the Multi-CD SSB (Multiple Cell Defining SSB, multi-unit definition synchronization/physical broadcast channel block) method , supports the establishment of multiple physical cells on the same carrier, each physical cell has independent configuration parameters; due to the networking method of multiple physical cells, it can support independent configuration of parameters between physical cells, such as power configuration and beam direction, etc. , Therefore, when both public network physical cells and private network physical cells are established on the same carrier, scenarios with different coverage requirements of public and private networks can be met. Since broadcasts are independent of each other, the public private network can be configured with different paging strategies, reselection strategies, and neighboring cells. Configuration etc.

Figure 1 shows a schematic diagram of a carrier in a Multi-SSB scenario according to an exemplary embodiment of the present application. As shown in Figure 1, multiple SSBs (Synchronization Signal/Physical Broadcast Channel Block, Synchronization/Physical Broadcast) can be configured on one carrier. Channel block); among them, multiple SSBs can be classified into CD-SSB (Cell Defining SSB, unit-defined SSB) 110 and non-CD-SSB 120; for example, SSB1 and SSB3 in Figure 1 are CD-SSB, and SSB2 and SSB4 are non-CD-SSB. CD-SSB; the CD-SSB can define a physical cell, which can have PCI (Physical Cell Identifier, physical cell identifier), initial CORESET (Control Resource Set, control resource set), initial BWP (Bandwidth Part, bandwidth Part), RMSI (Remaining Minimum SI, remaining system message), etc.

Based on the carrier schematic diagram shown in Figure 1, an embodiment of the present application provides a cell model, which includes a carrier, a physical cell and a logical cell; Figure 2 shows a schematic diagram of a cell model provided by an exemplary embodiment of the present application. As shown in Figure 2, multiple physical cells 220 can be established on the same carrier 210, and each physical cell can correspond to at least one logical cell 230.

The carrier 210 is a physical NR (New Radio) carrier on the network side (base station) under the cell model, including baseband, radio frequency, and antenna software and hardware resources, and can support the functions of one or more physical cells.

The physical cell 220 is a physical cell that can be sensed by the terminal side under the cell model; the physical cell can accept synchronous wireless access from the terminal to perform uplink/downlink data transmission. A physical cell can support the functions of one or more logical cells, and each physical cell can correspond to different logical cells according to different operators. Each physical cell corresponds to a CD-SSB; the physical cell can also be called a physical NR cell or a physical DU (Distributed Unit) cell; it should be noted that in order to meet the public and private network convergence scenarios, the embodiment of this application , the physical cells built on the same carrier include at least one public network physical cell and at least one private network physical cell.

The logical cell 230 is a logical cell that can be sensed by the terminal side under the cell model; the terminal senses all logical cells by receiving the SIB1 (System Information Block Type 1, system message block type 1) message of the physical cell, and the terminal selects the When PLMN (Public Land Mobile Network) is used, a logical cell is also selected; the logical cell can also be called a logical NR cell or a logical DU cell.

Taking two physical cells built on the same carrier as an example, Figure 3 shows a cell model framework diagram according to an exemplary embodiment of the present application. As shown in Figure 3, two physical cells are built on the carrier 310, that is, the physical Cell 1 and physical cell 2, where physical cell 1 is used for access and business processing of public network terminals, and physical cell 2 is used for access and business processing of private network terminals. That is, physical cell 1 is a public network physical cell. Cell 2 is a private network physical cell, and the two physical cells share the same carrier spectrum resource. Both physical cells have independent configurations such as CD-SSB, initial CORESET, initial BWP, and RMSI.

In the scenario of integrated public and private network deployment, in order to achieve physical isolation between public and private networks, in a possible implementation method, the public network physical cell and the private network physical cell can be deployed separately with baseband boards, or the public network physical cell and the private network physical cell can be deployed separately. Network physical cells and private network physical cells can be divided into baseband processing units (Building Base band Unit (BBU) frame deployment, through cross-board/or cross-frame deployment of public network physical cells and private network physical cells, the hardware physical isolation of public network physical cells and private network physical cells can be achieved.

In the data processing stage, the network equipment can realize the data processing process of each physical cell of the public private network by cooperatively scheduling the air interface resources of each physical cell in the cell model.

This application takes the collaborative scheduling process of the air interface resources of the first physical cell in the cell model as an example. The air interface resource scheduling process of any physical cell in the cell model can refer to the air interface resource scheduling process of the first physical cell. This application No need to go into details; the first physical cell may be a public network physical cell or a private network physical cell. This data processing method includes:

When the target physical cell contains two physical cells, the target physical cell includes a public network physical cell and a private network physical cell; at this time, if the first physical cell is a public network physical cell, the second physical cell is a private network physical cell. network physical cell; if the first physical cell is a private network physical cell, the second physical cell The management cell is a public network physical cell, that is, the interaction of cell configuration parameters between the public network physical cell and the private network physical cell can be achieved through the above steps.

When the target physical cell contains more than two physical cells, the target physical cell includes at least one public network physical cell and at least one private network physical cell; at this time, the first physical cell can be a public network physical cell or a private network physical cell. network physical cell, and the second physical cell is another physical cell in the target physical cell except the first physical cell. Through the above steps, the interaction of cell configuration parameters between the first physical cell and other physical cells on the same carrier can be achieved. , this process may include cell configuration parameter interaction between the public network physical cell and the private network physical cell, the cell configuration parameter interaction between the public network physical cell and the public network physical cell, and the private network physical cell and the private network physical cell. Cell configuration parameter interaction between cells.

In a possible implementation, after the public and private network physical cells (ie, the public network physical cell and the private network physical cell) are established and configured, the physical cells can exchange configuration parameters of the physical cells with the first physical cell. Taking a cell as an example, after the first physical cell and the second physical cell are established and configured, the first physical cell can send the configuration parameters of the first physical cell to the second physical cell, and receive the second physical cell sent by the second physical cell. The configuration parameters of the cell.

Step 530: Receive the second information sent by the second physical cell through the first physical cell. The second information is sent by the second physical cell when a terminal performs shared channel service scheduling; the second information includes: second physical cell At least one of the scheduling size of the cell, terminal correlation information, and scheduling priority information of the second physical cell.

Illustratively, when the cell model contains two physical cells, and the second physical cell is a public network physical cell, and the first physical cell is a private network physical cell, when there are terminals in the public network physical cell for shared channel service scheduling , before performing data transmission on the shared channel, the second physical cell notifies the private network physical cell of the second information; at this time, the second information includes: the scheduling size of the public network physical cell, terminal correlation information and the public network physical cell At least one of the scheduling priority information.

The shared channel service scheduling can be implemented as PDSCH (Physical Downlink Shared Channel, physical downlink shared channel) service scheduling or PUSCH (Physical Uplink Shared Channel, physical uplink shared channel) service scheduling.

When the cell model contains two physical cells, and the second physical cell is a private network physical cell, and the first physical cell is a public network physical cell, when there are terminals in the private network physical cell for shared channel service scheduling, sharing is performed Before transmitting data on the channel, the second information is notified to the private network physical cell; at this time, the second information includes: at least one of: the scheduling size of the private network physical cell, the terminal correlation information, and the scheduling priority information of the public network physical cell. A sort of.

The scheduling size is used to indicate the size of the scheduling service corresponding to the terminal.

The terminal correlation information is information used to determine channel related information between the terminal and other terminals. Illustratively, when the first physical cell receives the second information and there is a first terminal access, the first The physical cell may determine the channel correlation between the first terminal and the second terminal based on terminal correlation information of the second terminal accessing the second physical cell and terminal correlation information of the first terminal.

The scheduling priority information is used to indicate the execution order of shared channel service scheduling requests received by the physical cell.

Optionally, the second information is sent by the second physical cell on the air interface n timeslots (slots) in advance when a terminal is scheduled for shared channel service; n is a positive number; where corresponding to different terminals, There are different settings for the number of time slots; schematically, it is assumed that for ordinary terminals, the second information can be sent over the air interface 1 time slot in advance; for URLLC (Ultra-Reliable and Low Latency Communications) terminals, the second information can be sent in advance The air interface sub-slot (mini slot) sends the second information, and the number of slots corresponding to the mini slot is less than 1; it should be noted that corresponding to different access terminals, relevant personnel can set the adaptive number of time slots. This application does not limit this.

Optionally, when a terminal in the first physical cell performs shared channel service scheduling, before data transmission on the shared channel is performed, the first information is notified to the second physical cell through the first physical cell, and the first information includes the first information. At least one of the scheduling size of a physical cell, terminal correlation information, and scheduling priority information of the first physical cell.

In a possible implementation, when the first terminal accesses the first physical cell, the terminal-level configuration parameters are notified to the second physical cell through the first physical cell. The terminal-level configuration parameters may include PDCCH ( Physical resources such as Physical Downlink Control Channel), PUCCH (Physical Uplink Shared Channel), SRS (Sounding Reference Signal), CSI-RS (CSI reference signal, CSI reference signal) Configuration parameters. Correspondingly, the terminal-level configuration parameters sent by the second physical cell when accessing the second terminal are received through the first physical cell.

Optionally, since the target physical cells are deployed across boards or frames, when the schedulers of each target physical cell perform collaborative scheduling, they can exchange parameter information based on the transmission channel between the schedulers.

Illustratively, when the first physical cell and the second physical cell are located on different baseband boards, the network device may send the configuration parameters of the first physical cell to the second physical cell through the first physical cell based on the baseband board transmission channel. , and receives the configuration parameters of the second physical cell fed back by the second physical cell through the first physical cell; based on the baseband board transmission channel, receives the second information sent by the second physical cell through the first physical cell; the baseband board transmission channel is used To achieve communication between baseband boards. That is to say, when the first physical cell and the second physical cell are deployed across boards, parameter information can be exchanged between the first physical cell and the second physical cell through the baseband board transmission channel.

In the case where the first physical cell and the second physical cell are located on different BBU frames, the network device may send the configuration parameters of the first physical cell to the second physical cell through the baseband processing unit transmission channel, and pass The first physical cell receives the configuration parameters of the second physical cell fed back by the second physical cell; and receives the second information sent by the second physical cell through the first physical cell based on the baseband processing unit transmission channel, which is used for Implement communication between baseband processing units. That is to say, when the first physical cell and the second physical cell are deployed across frames, parameter information can be exchanged between the first physical cell and the second physical cell through the baseband processing unit transmission channel.

Taking the target physical cell as an example including two physical cells, Figure 8 shows a schematic diagram of scheduler collaboration and interaction provided by an exemplary embodiment of the present application. As shown in Figure 8, the public network physical cell 810 and the private network The physical cells 820 realize collaboration between schedulers through transmission channels (including baseband board transmission channels and baseband processing unit transmission channels). The cooperation content includes: after the public private network physical cell is established, the two physical cells use transmission channels to The channel exchanges the configuration parameters of each physical cell, such as physical cell bandwidth, frequency domain location, BWP, SSB, PRACH configuration, etc.; after the terminal of the public private network physical cell is connected, the two physical cells exchange terminal-level information through the transmission channel. Configuration parameters, such as PDCCH, PUCCH, SRS, CSI-RS and other physical resource configurations; when there are terminals in the public network physical cell that need to perform PDSCH/PUSCH scheduling, the scheduling size, terminal correlation information and scheduling priority information will be set n slots in advance Notify the private network physical cell; when a terminal in the private network physical cell needs to perform PDSCH/PUSCH scheduling, notify the public network physical cell of the scheduling size, terminal correlation information, and scheduling priority information n slots in advance.

Step 540: Schedule the shared channel of the first physical cell through the first physical cell according to the scheduling information; wherein the scheduling information includes: configuration parameters of the first physical cell, configuration parameters of the second physical cell, first information, and Second information; the first information includes at least one of the scheduling size of the first physical cell, terminal correlation information, and scheduling priority information of the first physical cell.

That is to say, when the first physical cell schedules the shared channel of this physical cell, it needs to refer to the second information notified by the second physical cell, the configuration parameters of the second physical cell, and the configuration parameters and first information of this physical cell. Carry out comprehensive scheduling.

Optionally, according to the scheduling information, the process of scheduling the shared channel of the first physical cell through the first physical cell can be implemented as:

When the terminal correlation information of each target physical cell satisfies the spatial division condition, spatial division scheduling is performed on the shared channel of the first physical cell through the first physical cell. After spatial division scheduling, the frequency domain of the shared channel of the first physical cell is The location may overlap with the frequency domain location of the shared channel of the second physical cell.

That is to say, when the first physical cell determines that the channel correlation of each terminal satisfies the spatial division condition based on the received terminal correlation information of each second physical cell, the shared channel of the physical cell can be scheduled. The frequency domain location of the shared channel of the first physical cell may overlap with the frequency domain location of the shared channel of the second physical cell.

When the terminal correlation information of each target physical cell does not meet the spatial division condition, based on the frequency domain position of the cell definition synchronization block CD-SSB of each target physical cell, the shared channel of the first physical cell is used by the first physical cell.
