The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.

In the conventional mobile communication technology, carriers and physical cells are in one-to-one correspondence, that is, one carrier corresponds to one physical cell; in the technical field of 5G mobile communication, a concept of multiple synchronization/physical broadcast channel blocks (Multiple Synchronization Signal/PBCH Block, multi-SSB) is introduced; in a Multi-SSB scenario, there may be multiple cells on one carrier; in the embodiment of the application, a Multi-CD SSB mode is adopted to support the establishment of a plurality of physical cells on the same carrier, and each physical cell has mutually independent configuration parameters; because the independent configuration of parameters between physical cells, such as power configuration and beam direction, can be supported by networking multiple physical cells, when the public network physical cells are built on the same carrier, and the private network physical cells are built, the different coverage requirements of the public and private networks can be met. Because the broadcasting is independent, the public and private network can be configured with different paging strategies, reselection strategies, neighbor cell configurations and the like.

Fig. 1 shows a schematic carrier diagram in a Multi-SSB scenario, which is shown in an exemplary embodiment of the present application, and as shown in fig. 1, multiple SSBs (Synchronization Signal/Physical Broadcast Channel Block, synchronization/physical broadcast channel blocks) may be configured on one carrier; among them, the plurality of 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 FIG. 1 are CD-SSB, SSB2 and SSB4 are non-CD-SSB; the CD-SSB may define a physical cell that may have PCI ((Physical Cell Identifier, physical cell identity), initial CORESET (Control Resource Set ), initial BWP (Bandwidth Part), RMSI (Remaining Minimum SI, remaining system messages), etc.

Based on the carrier schematic diagram shown in fig. 1, the embodiment of the application provides a cell model, where the cell model includes a carrier, a physical cell and a logical cell; fig. 2 illustrates a schematic diagram of a cell model provided in an exemplary embodiment of the present application, as shown in fig. 2, a plurality of physical cells 220 may be established on the same carrier 210, and each physical cell may correspond to at least one logical cell 230.

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

The physical cell 220 is a physical cell perceivable by a terminal side under a cell model; the physical cell can accept synchronous wireless access of the terminal, thereby carrying out uplink/downlink data transmission. The physical cells may support the functionality of one or more logical cells, each of which may correspond to a different logical cell according to a different operator. A CD-SSB corresponding to each physical cell; the physical cell may also be referred to as a physical NR cell or a physical DU (Distributed Unit) cell; in order to meet the convergence scenario of public and private networks, in the embodiment of the present application, the physical cells set up on the same carrier wave include at least one public network physical cell and at least one private network physical cell.

The logical cell 230 is a logical cell perceivable at a terminal side under a cell model; the terminal perceives all the logic cells by receiving SIB1 (System Information Block Type, system message block type 1) information of the physical cells, and when PLMN (Public Land Mobile Network ) is selected during terminal access, the logic cells are also selected simultaneously; the logical cell may also be referred to as a logical NR cell or a logical DU cell.

Taking the example that two physical cells are set up on the same carrier, fig. 3 shows a cell model frame diagram shown in an exemplary embodiment of the present application, as shown in fig. 3, two physical cells, namely, a physical cell 1 and a physical cell 2, are set up on a carrier 310, where the physical cell 1 is used for access and service processing of a public network terminal, the physical cell 2 is used for access and service processing of a private network terminal, namely, the physical cell 1 is a public network physical cell, the physical cell 2 is a private network physical cell, and the two physical cells share the same carrier spectrum resource. On both physical cells there are independent CD-SSB, initial CORESET, initial BWP, RMSI etc. configurations.

In a scenario of public-private network convergence deployment, in order to achieve the purpose of physical isolation between public-private networks, in one possible implementation manner, a public-network physical cell and a private-network physical cell may be deployed in a baseband board, or a public-network physical cell and a private-network physical cell may be deployed in a baseband processing unit (Building Base band Unit, BBU) frame, and hardware physical isolation between the public-network physical cell and the private-network physical cell may be achieved through cross-board and/or cross-frame deployment of the public-network physical cell and the private-network physical cell.

Based on the cell model shown in fig. 2 or fig. 3, fig. 4 shows a flowchart of a data processing method provided in an exemplary embodiment of the present application, where the method may be performed by a network device, and the network device may be a management device on a base station side, as shown in fig. 4, and the data processing method includes:

step 410, a cell model is established, wherein the cell model comprises a public network physical cell and a private network physical cell, and the public network physical cell and the private network physical cell are built on the same carrier; the public network physical cell and the private network physical cell are positioned on different baseband boards, or the public network physical cell and the private network physical cell are positioned on different baseband processing unit BBU frames.

In the embodiment of the present application, the physical cell of the public network and the physical cell of the private network may be used to refer to the functional classification of the physical cells carried on the same carrier, without limiting the number of the physical cells carried on the same carrier; that is, at least one physical cell of the public network and at least one physical cell of the private network may be carried on the same carrier, and the number of physical cells of the public network and the number of physical cells of the private network carried on the same carrier are not limited in this application.

Step 420, cooperatively scheduling air interface resources through each target physical cell in the cell model; the target physical cell includes a public network physical cell and a private network physical cell.

In this embodiment of the present application, the physical public network cell and the physical private network cell are disposed across boards (on different baseband boards) or across frames (on different baseband processing units), and because the public network and the private network share the same carrier resource, when the physical public network cell and the physical private network cell perform data processing in this scenario, the air interface resource needs to be scheduled to meet the data processing requirement between the physical public network cell and the physical private network cell. The target physical cells can realize cooperative scheduling of air interface resources through cooperative processing of a scheduler.

And step 430, respectively performing data processing through the physical layer of each target physical cell based on the air interface resources respectively corresponding to each target physical cell.

That is, the physical layer of each target physical cell performs data processing based on the respective air interface resources obtained after the coordinated scheduling.

Step 440, combining and transmitting the in-phase quadrature IQ data of each target physical cell; the IQ data is data obtained after data processing by the physical layer.

Since the target physical cells share the same carrier resource, when transmitting IQ data of each target physical cell, IQ data of each target physical cell needs to be combined, where the combination may refer to that IQ data of each target physical cell is superimposed into one data.

In summary, in the data processing method provided in the embodiment of the present application, by establishing the cell model, the public network physical cell and the private network physical cell are carried on the same carrier, and the public network physical cell and the private network physical cell are deployed across boards or frames, so that the independent configuration of the public network physical cell parameters is realized, and the physical isolation of the public network physical cell is also realized;

Correspondingly, the configuration parameters of the terminal level transmitted by the second physical cell under the condition of accessing the second terminal are received through the first physical cell.

Alternatively, due to cross-board or cross-frame deployment between the target physical cells, when schedulers of the respective target physical cells perform cooperative scheduling, parameter information interaction can be performed based on transmission channels between the schedulers.

Illustratively, in the case that the first physical cell and the second physical cell are located in different baseband boards, the network device may send, based on the baseband board transmission channel, configuration parameters of the first physical cell to the second physical cell through the first physical cell, and receive, through the first physical cell, configuration parameters of the second physical cell fed back by the second physical cell; receiving second information sent by a second physical cell through the first physical cell based on a baseband board transmission channel; the baseband board transmission channel is used for realizing communication between the baseband boards. That is, in the case of the cross-board deployment of the first physical cell and the second physical cell, the interaction of the parameter information between the first physical cell and the second physical cell may be performed through the baseband board transmission channel.

That is, in the case of the cross-frame deployment of the first physical cell and the second physical cell, the interaction of the parameter information between the first physical cell and the second physical cell may be performed through the baseband processing unit transmission channel.

Taking an example that the target physical cell includes two physical cells, fig. 8 shows a schematic diagram of scheduler cooperation interaction provided in an exemplary embodiment of the present application, as shown in fig. 8, where cooperation between schedulers is implemented between the public network physical cell 810 and the private network physical cell 820 through a transmission channel (including a baseband board transmission channel and a baseband processing unit transmission channel), and cooperation contents include: after the physical cells of the public and private network are established, the configuration parameters of each physical cell, such as the bandwidth of the physical cell, the frequency domain position, BWP, SSB, PRACH configuration and the like, are interacted between the two physical cells through a transmission channel; after the terminal of the physical cell of the common private network is accessed, the configuration parameters of the terminal level, such as PDCCH, PUCCH, SRS, CSI-RS and other physical resource configuration, are interacted between the two physical cells through a transmission channel; when a public network physical cell has a terminal to carry out PDSCH/PUSCH scheduling, n slots are advanced to inform a private network physical cell of scheduling size, terminal correlation information and scheduling priority information; when a terminal needs to perform PDSCH/PUSCH scheduling in a private network physical cell, n slots are advanced to inform a public network physical cell of scheduling size, terminal correlation information and scheduling priority information.

That is, when the first physical cell determines that the channel correlation of each terminal satisfies the space division condition based on the received terminal correlation information of each second physical cell, the shared channel of the own physical cell may be scheduled, and the frequency domain position of the shared channel of the scheduled first physical cell may overlap with the frequency domain position of the shared channel of the second physical cell.

And under the condition that the terminal correlation information of each target physical cell does not meet the space division condition, scheduling the shared channel of the first physical cell through the first physical cell based on the frequency domain position of the cell definition synchronization block CD-SSB of each target physical cell.

In one possible implementation, the first physical cell schedules the shared channel of the physical cell based on a relative frequency band relationship of a first frequency domain location where the CD-SSB of the physical cell is located relative to a second frequency domain location where the CD-SSB of the second physical cell is located.

Taking an example that the target physical cell includes two physical cells, fig. 9 shows a schematic diagram of shared channel scheduling provided in an exemplary embodiment of the present application, and as shown in fig. 9, the shared channel scheduling process includes:

S901, the physical cell judges whether the channel correlation between the terminals meets the space division condition according to the terminal correlation information notified by the opposite-end physical cell. If yes, S902 is executed, otherwise S903 is executed.

The physical cell can refer to any one of a private network physical cell and a public network physical cell, and when the physical cell is the public network physical cell, the opposite-end physical cell is the private network physical cell; when the physical cell is a private network physical cell, the opposite-end physical cell is a public network physical cell.

The frequency domain locations of the two physical cells after scheduling may overlap.

S903, judging the frequency band of the first frequency domain position relative to the second frequency domain position; if the first frequency domain position is in the low frequency band with respect to the second frequency domain position, S904 is performed, and if the first frequency domain position is in the high frequency band with respect to the second frequency domain position, S905 is performed.

The first frequency domain position is the frequency domain position where the CD-SSB of the physical cell is located, and the second frequency domain position is the frequency domain position where the CD-SSB of the opposite physical cell is located.

S904, the physical cell allocates resource blocks of the shared channel in the order from the low frequency to the high frequency.

in a carrier interval where the first frequency domain position is located, allocating resource blocks to a shared channel of a first physical cell through the first physical cell according to the sequence from low frequency to high frequency;

Optionally, the frequency domain ranges corresponding to the at least three carrier intervals are not coincident; illustratively, taking an example that the target physical cell includes three physical cells, if the frequency domain position 2 of the physical cell 2 is located in a middle frequency band relative to the frequency domain position 1 of the physical cell 1 and the frequency domain position 3 of the physical cell 3, the frequency domain position 1 is located in a lowest frequency band, and the frequency domain position 3 is located in a highest frequency band, the carrier bandwidth can be divided into three carrier intervals; the frequency domain ranges of the three carrier intervals are not overlapped; the physical cell 1 is allocated with resource blocks in the order from the low frequency to the high frequency of the carrier, the physical cell 3 is allocated with resource blocks in the order from the high frequency to the low frequency of the carrier, and the physical cell 2 is allocated with resource blocks in the order from the low frequency to the high frequency of the carrier in the carrier section where the frequency domain position 2 is located.

Optionally, when the scheduling information includes scheduling priority information, it needs to ensure that the physical cell with higher scheduling priority performs advanced scheduling, and at this time, when the sum of the number of the first resource blocks and the number of the second resource blocks is greater than the number of the resource blocks of the carrier bandwidth, the physical shared channel of the first physical cell is allocated by the first physical cell according to the scheduling priority sequence indicated by the scheduling priority information;

the first resource block number is the resource block allocated by the first physical cell, and the second resource block is the resource block pre-allocated by the second physical cell.

Illustratively, in the case that the target physical cell includes two physical cells, if the scheduling priority of the second physical cell is higher than that of the first physical cell, and the sum of the number of the first resource blocks and the number of the second resource blocks exceeds the number of the carrier bandwidth resource blocks, the resource blocks of the second physical cell need to be allocated first, and then the resource blocks of the first physical cell need to be allocated.
