Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for configuring a frame structure, and a storage medium.

Background

In a mobile communication system, data is transmitted over a wireless air interface in units of frames, one frame being one data transmission period. For a Time Division Duplex (TDD) system, uplink data and downlink data are transmitted in a same data frame by time division multiplexing, and one frame simultaneously includes an uplink symbol, a downlink symbol, and a special symbol. In this case, there may be uplink and downlink cross interference between cells supporting different frame structures.

The general technique is generally to reduce interference by manually setting isolation regions (i.e., when deploying base stations, increasing the spatial distance between base stations supporting different frame structures, and setting an isolation region between two base stations). However, this approach may affect the continuity of signal coverage and affect the interference suppression effect.

Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs.

To facilitate an understanding of the present application, the relevant elements referred to in the present application will now be described.

Frame structure

In a mobile communication system, data is transmitted over a wireless air interface in units of frames, one frame being one data transmission period. According to the protocol, each network type has a corresponding standardized frame structure, and the frame structures corresponding to different network types are different. To support coexistence between different systems, different types of frame structures typically have the same frame length.

For any frame structure, a frame may be divided into smaller sub-transmission units, such as slots or subframes. Each sub-transmission unit contains a certain number of symbols. Each symbol corresponds to a symbol type. Different types of symbols are used to implement different transmission functions. The symbol types can be divided into uplink symbols, downlink symbols, special symbols. The uplink and downlink symbols are used for uplink and downlink data transmission, respectively. The special symbols do not carry out any data transmission.

For a TDD system, uplink and downlink data are transmitted in the same data frame by time division multiplexing. One frame includes uplink symbols, downlink symbols and special symbols. The number of uplink symbols, downlink symbols, and special symbols included in different types of frame structures, and the position arrangement of each symbol in the time domain may be different.

Taking the fifth generation mobile communication technology (5G) TDD system as an example, a frame is 10ms long, each frame includes a plurality of slots, and each slot includes 14 symbols. The length of each symbol and the number of symbols included in each frame vary according to the subcarrier spacing, and the symbol length is inversely proportional to the size of the subcarrier spacing in the frequency domain.

Illustratively, the 5G supports a maximum subcarrier spacing of 240KHz, a corresponding minimum symbol length of 4.46us, and a corresponding number of 2240 symbols per frame. The minimum subcarrier spacing is 15KHz, corresponding to a maximum symbol length of 71.35us, and each frame contains 140 symbols.

For a certain subcarrier interval, the 5G TDD system can also support different types of frame structures to meet the requirements of different service areas.

For example, when the subcarrier spacing is 15KHz, the 5G TDD cell may be configured with two different types of frame structures in different regions, as follows:

the first frame structure: DDDSU DDSUU

The second frame structure: DSUUUU DSUU

Wherein, a frame comprises 10 time slots, D represents a downlink time slot, and comprises 14 downlink symbols; u represents an uplink slot, which includes 14 uplink symbols; s represents a special time slot, which sequentially includes 10 downlink symbols, 2 special symbols (the base station transceiver does not perform any data transmission within the symbol time), and 2 uplink symbols in time order.

The frame structure of the TDD system is generally pre-configured, and a corresponding frame structure type is determined according to a service scenario corresponding to a cell and statically configured in a base station in a network planning process.

Exemplarily, in a 2C scenario, a service requirement is mainly downlink service, and a TDD cell is configured to have a frame structure (a first frame structure) in which the number of downlink symbols is large; if the 2B scene is dominated by the uplink service, a frame structure (second frame structure) with a larger uplink symbol number is configured.

For a TDD system, supporting multiple frame structures is beneficial to flexibly meeting service requirements of different scenes, but in general, it is necessary to keep frame structure types of adjacent cells consistent. If different types of frame structures are deployed in the same area, uplink and downlink cross interference is caused, and the performance of a cell is affected.

Illustratively, if the uplink symbol time of the first frame structure corresponds to the downlink symbol time of the second frame structure, the downlink signal of the second frame structure will fall into the base station receiver supporting the first frame structure, resulting in interference to the cell supporting the first frame structure.

As described in the general technology, in order to avoid the influence of the uplink and downlink cross interference on the performance of the cell, an isolation region is generally manually set (i.e., when the base stations are deployed, the spatial distance between the base stations supporting different frame structures is increased, and an isolation region is set between two base stations) to reduce the interference. However, this approach may affect the continuity of signal coverage and affect the interference suppression effect.

In view of the above problems, an embodiment of the present application provides a frame structure configuration method, where after a candidate frame structure of a target cell and an associated frame structure of an associated cell adjacent to the target cell are obtained, if the associated frame structure is different from the candidate frame structure, a time domain position and a symbol type of an interference symbol in the associated frame structure and the candidate frame structure are determined, and a target frame structure of the target cell and a target frame structure of the associated cell are determined according to the time domain position and the symbol type of the interference symbol, a traffic predicted value and a traffic type parameter predicted value of the target cell, and a traffic predicted value and a traffic type parameter predicted value of the associated cell. Therefore, the method and the device can reduce the inter-cell interference supporting different frame structures by adjusting the frame structure, meet the service performance requirement of the cell, and solve the technical problem of low interference suppression effect in the general technology.

The frame structure configuration method is suitable for a frame structure configuration system. Fig. 1 shows one structure of the frame structure configuration system. As shown in fig. 1, the frame configuration system includes, in a predetermined area: management module, base station 1 and base station 2.

Wherein, the management module is respectively connected with the base station 1 and the base station 2 in a communication way. The area covered by the base station 1 is a cell 1 (i.e. a target cell in the present application). The area covered by the base station 2 is a cell 2 (i.e. an associated cell in this application).

The predetermined area is an area defined in the network and includes at least one base station (fig. 1 illustrates a base station 1 and a base station 2 as an example). The cells in the preset area may be TDD cells, that is, both cell 1 and cell 2 are TDD cells.

The management module is used for realizing the frame structure management function in the preset area and has a message interaction interface with the base station where each cell in the preset area is located. The management module is a functional entity, and the physical entity may be located in a certain base station, core network equipment, and a base station operation and maintenance platform in a preset area, or may be located in an independent physical device.

Optionally, the management module may also be a server. The server may be one server in a server cluster (composed of a plurality of servers), a chip in the server, a system on chip in the server, or a virtual machine deployed on a physical machine, which is not limited in this embodiment of the present application.

As shown in fig. 3, the frame structure configuration means may comprise a processor 31 and a communication interface 32. The processor 31 is coupled to a communication interface 32.

The function of the processor 31 may refer to the description of the processor 21 above. The processor 31 also has a memory function and can function as the memory 22.

The communication interface 32 is used to provide data to the processor 31. The communication interface 32 may be an internal interface of the frame configuration apparatus, or may be an external interface (corresponding to the communication interface 23) of the frame configuration apparatus.

It is noted that the structure shown in fig. 2 (or fig. 3) does not constitute a limitation of the frame structure configuration means, which may include more or less components than those shown in fig. 2 (or fig. 3), or combine some components, or a different arrangement of components, in addition to the components shown in fig. 2 (or fig. 3).

The following describes a frame configuration method provided in an embodiment of the present application in detail with reference to the accompanying drawings.

As shown in fig. 4, the frame structure configuration method provided in the embodiment of the present application is applied to the management module shown in fig. 1. The frame structure configuration method comprises the following steps:

s401, the management module obtains a candidate frame structure of the target cell.

In an implementation manner, the target cell may obtain the traffic parameter corresponding to each unit time interval according to a preset cycle. Then, the management module may obtain a traffic parameter value of the target cell at any time period (e.g., within a preset historical time). Then, the management module may determine a candidate frame structure corresponding to the traffic parameter value based on a preset mapping rule.

Wherein the preset cycle length is the same as the unit time interval length. The traffic parameter includes uplink traffic and downlink traffic, which can be respectively defined as one or two combinations of uplink and downlink PRB resource utilization or data traffic.

Illustratively, the unit period is 5 minutes in length.

In another implementation manner, the frame structure of the TDD system in the general technology is pre-configured, and cannot be dynamically adjusted based on the uplink and downlink service change condition of the system, so that it is difficult to meet different uplink and downlink service requirements of the system in different time periods in real time. In this case, the management module may obtain a traffic parameter value of the target cell within a preset historical time, and then predict, based on the artificial intelligence algorithm model, to obtain a traffic prediction value of the target cell within a preset future time, and determine, based on a preset mapping rule, a candidate frame structure corresponding to the traffic prediction value.

Therefore, the management module dynamically determines the target frame structure in the preset future time according to the predicted traffic value of the target cell and the inter-cell interference situation supporting different frame structures, so as to adaptively match the uplink and downlink service requirements, and solve the technical problem that the general technology is difficult to meet different uplink and downlink service requirements of the system in different time periods in real time.

S402, the management module acquires the associated frame structure of the associated cell adjacent to the target cell.

The associated cell is any adjacent associated cell of the target cell. The associated frame structure is a frame structure currently configured for the associated cell.

Specifically, in order to avoid interference between cells supporting different frame structures, the management module may determine an associated cell corresponding to the target cell, identify a potential adjacent cell having interference with the target cell by determining, as the associated cell, an adjacent cell having a smaller distance from the target cell or having a signal coverage area including a base station where the target cell is located, and acquire an associated frame structure of the associated cell adjacent to the target cell.

In an implementation manner, the method for acquiring, by a management module, an association frame structure of an association cell adjacent to a target cell specifically includes:

the management module sends a first request message to a base station where the associated cell is located. The first request message is used for requesting to acquire a frame structure currently configured by the associated cell. The first request message carries the identification of the associated cell.

The management module receives a first response message sent by a base station where the associated cell is located. The first response message carries the identifier of the associated cell and the identifier of the currently configured frame structure of the associated cell.

And the management module determines the frame structure corresponding to the identifier of the frame structure currently configured by the associated cell as the associated frame structure.

Specifically, when acquiring the associated frame structure of the associated cell adjacent to the target cell, the management module may send a first request message to the base station where the associated cell is located, where the first request message is used to request to acquire the frame structure currently configured by the associated cell. The first request message carries the associated cell identifier. Next, the base station where the associated cell is located may send a first response message to the management module. The first response message carries the associated cell identifier and the frame structure identifier currently configured by the associated cell.

In the present application, the execution order of S401 and S402 is not limited. The management module may perform S401 first and then S402; or executing S402 first and then executing S401; s401 and S402 may also be performed simultaneously.

S403, if the associated frame structure is different from the candidate frame structure, the management module determines the time domain position and the symbol type of the interference symbol in the associated frame structure and the candidate frame structure.

Specifically, if the frame structure of the candidate frame of the target cell is different from that of the associated cell, it indicates that uplink and downlink cross interference will occur between the target cell and the associated cell. In this case, the management module may determine the time domain position and the symbol type of the interference symbol in the associated frame structure and the candidate frame structure according to the relationship between the associated cell frame structure and the target cell candidate frame structure, so as to facilitate subsequent adjustment of the candidate frame structure of the target cell or the frame structure of the associated cell according to the time domain position and the symbol type of the interference symbol to avoid interference and ensure the service performance of the cell.

And if the associated frame structure is the same as the candidate frame structure, the management module determines the candidate frame structure as a target frame structure of the target cell in a preset future time.

In one implementation, the target frame structure may be a frame structure to be configured within a preset future time.

Specifically, if the frame structure of the candidate frame structure of the target cell is the same as the frame structure of the associated cell, after the frame structure of the target cell is reconfigured into the frame structure of the candidate frame structure, there is no interference between the target cell and the associated cell, and the frame structure of the candidate frame structure is determined as the frame structure of the target. Otherwise, uplink and downlink cross interference will occur between the target cell and the associated cell. The management module needs to avoid interference by adjusting a candidate frame structure of a target cell or a frame structure of an associated cell, so as to ensure the service performance of the cell.

S404, the management module determines a target frame structure of the target cell and a target frame structure of the associated cell according to the time domain position and the symbol type of the interference symbol, the traffic predicted value and the traffic type parameter predicted value of the target cell, and the traffic predicted value and the traffic type parameter predicted value of the associated cell.

In an implementation manner, after determining the time domain position and the symbol type of the interference symbol in the associated frame structure and the candidate frame structure, the management module may determine a policy for adjusting the frame structures of the target cell and the associated cell according to the time domain position and the symbol type of the interference symbol.

When the strategy for adjusting the frame structures of the target cell and the associated cell is to adjust the uplink and downlink symbols in the frame structure to silent symbols, the strategy for adjusting the uplink and downlink symbols in the frame structure to silent symbols may cause the number of symbols available for uplink and downlink data transmission to be reduced and affect the service transmission delay and rate of the cell because data transmission and reception are not performed within the silent symbol time.

In this case, the management module may take into account the traffic volume prediction value and the traffic type parameter prediction value when determining the silence symbol. And determining the interference symbol as a silent symbol only when the predicted value of the traffic volume and the predicted value of the traffic type parameter meet a preset condition, namely the traffic volume of the cell in a preset future time is small and the low-delay service and the high-speed service account for less. Therefore, the management module determines the silent symbol according to the traffic predicted value and the traffic type parameter predicted value, and adjusts the candidate frame structure of the target cell or the associated frame structure of the associated cell, thereby avoiding the interference between cells and avoiding the influence of the frame structure adjustment on the service performance of the cell, and ensuring that the adjusted frame structure can simultaneously meet the requirements of the traffic and the service performance of the cell.

In one embodiment, the determining, by the management module, a target frame structure of the target cell and a target frame structure of the associated cell according to the time domain position and the symbol type of the interference symbol, the traffic predicted value and the traffic type parameter predicted value of the target cell, and the traffic predicted value and the traffic type parameter predicted value of the associated cell includes:

and corresponding to the time domain position of the interference grid, when the symbol type of the candidate frame structure is a downlink symbol and the target cell meets a preset condition, or the symbol type of the candidate frame structure is an uplink symbol and the associated cell does not meet the preset condition and the target cell meets the preset condition, adjusting the symbol corresponding to the interference grid in the candidate frame structure to be a silent symbol to obtain the adjusted candidate frame structure.

Wherein the preset conditions include: the predicted value of the traffic is smaller than a preset traffic threshold, and the predicted value of the service type parameter is smaller than a preset percentage threshold.

And corresponding to the time domain position of the interference grid, when the symbol type of the candidate frame structure is a downlink symbol, the target cell does not meet the preset condition and the associated cell meets the preset condition, or the symbol type of the candidate frame structure is an uplink symbol and the associated cell meets the preset condition, adjusting the symbol corresponding to the interference grid in the associated frame structure to be a silent symbol to obtain the adjusted associated frame structure.

And corresponding to the time domain position of the interference grid, when the symbol type of the candidate frame structure is a downlink symbol or an uplink symbol and the target cell and the associated cell do not meet the preset condition, determining the interference grid as a collision grid.

In this application, if the target cell candidate frame structure is different from the associated cell frame structure, the management module may determine, according to a relationship between the associated cell frame structure and the target cell candidate frame structure, a symbol position at which uplink and downlink cross interference exists between the target cell and the associated cell, and further determine the interference grid. Subsequently, the candidate frame structure of the target cell or the associated frame structure of the associated cell is adjusted, and the symbol corresponding to the interference grid is determined as a silent symbol, so that interference is avoided, and the service performance of the target cell and the associated cell can be guaranteed.

In addition, since data is not transmitted and received within the silent symbol time, the number of symbols available for uplink and downlink data transmission is reduced by adjusting the uplink and downlink symbols in the frame structure to silent symbols, which affects the service transmission delay and rate of the cell.

In this case, the management module takes into account the traffic and traffic type parameter predictors when determining the silence symbols. And determining the symbol corresponding to the interference grid as a silent symbol only when the predicted values of the service volume and the service type parameters meet the preset conditions, namely the cell has small service volume in the preset future time and the low-delay service and the high-speed service account for less, otherwise, determining the grid as a collision grid.

Therefore, the management module determines the silent symbol according to the traffic and the predicted value of the traffic type parameter, and adjusts the candidate frame structure of the target cell or the associated frame structure of the associated cell, thereby avoiding the interference between cells and avoiding the influence of the frame structure adjustment on the service performance of the cell, so that the adjusted frame structure can simultaneously meet the requirements of the traffic and the service performance of the cell.

In an implementation manner, before the management module determines the target frame structure of the target cell and the target frame structure of the associated cell according to the time domain position and the symbol type of the interference symbol, the traffic predicted value and the traffic type parameter predicted value of the target cell, and the traffic predicted value and the traffic type parameter predicted value of the associated cell, the management module further includes:

and the management module sends a fifth request message to the base station where the target cell is located. The fifth request message is used for requesting to acquire the currently configured frame structure of the target cell. And the fifth request message carries the identification of the target cell.

And the management module receives a sixth response message sent by the base station where the target cell is located. And the sixth response message carries the identifier of the target cell and the identifier of the frame structure currently configured by the target cell.

And if the ratio of the number of collision grids in the candidate frame structure or the associated frame structure is greater than a preset percentage threshold, determining the frame structure currently configured in the target cell as the target frame structure of the target cell, and determining the associated frame structure as the target frame structure of the associated cell.

And if the candidate frame structure and the number of collision grids in the associated frame structure are not more than a preset percentage threshold, determining the adjusted candidate frame structure as the target frame structure of the target cell and determining the adjusted associated frame structure as the target frame structure of the associated cell.

Wherein, the ratio of the number of collision grids is the ratio of the number of collision grids to the total number of grids.

As can be seen from the above description, in the present application, if the traffic volume and the predicted value of the service type parameter do not satisfy the preset condition, the interference grid is determined as the collision grid.

Because the collision grids are used for indicating time domain positions where interference exists between cells supporting different frame structures, and the number of the collision grids is large, the interference between the cells supporting different frame structures is serious, therefore, in order to avoid that the service performance of the cells is affected, the management module can determine the currently configured frame structures of the target cell and the associated cell as the target frame structure in the future time under the condition that the number of the collision grids is large, and keep the frame structure of each cell unchanged in the preset future time so as to guarantee the service performance of each cell.

the management module acquires the service quantity parameter value of the associated cell in the preset historical time.

And the management module predicts the traffic predicted value of the associated cell in the preset future time according to the traffic parameter value and the prediction model.

Specifically, the management module may input the initial prediction model with a traffic parameter value of each unit time period of the associated cell within a preset historical time as sample data, to obtain the trained prediction model. The predictive model reflects the correspondence between the traffic volume and each unit period.

For the description of the prediction model, reference may be made to the above description of the prediction model in S502, which is not repeated herein.

In an implementation manner, the method for acquiring, by a management module, a traffic parameter value of an associated cell within a preset historical time specifically includes:

and the management module sends a sixth request message to the base station where the associated cell is located. The sixth request message requests to acquire the traffic parameter of each unit time interval within the preset historical time.

And the management module receives a seventh response message sent by the base station where the associated cell is located. The seventh response message carries the identifier of the associated cell and the traffic parameter value of the associated cell in each unit time interval within the preset historical time.

Specifically, the management module may send a sixth request message to the base station where the associated cell is located, where the sixth request message is used to request to acquire the traffic parameter of each unit time period within the preset historical time. The sixth request message carries preset historical time information.

The preset historical time is a period of time before the current moment, and the preset historical time length can be preset in the management module.

Then, the base station where the associated cell is located may send a seventh response message to the management module, where the seventh response message carries the associated cell identifier and the traffic parameter value of the associated cell in each unit time period within the preset historical time.

In an embodiment, with reference to fig. 4 and as shown in fig. 5, in the above S401, the method for acquiring, by a management module, a candidate frame structure of a target cell specifically includes:

s501, the management module obtains the service volume parameter value of the target cell in the preset historical time.

In an implementation manner, the method for acquiring, by a management module, a traffic parameter value of a target cell within a preset historical time specifically includes:

and the management module sends a second request message to the base station where the target cell is located. The second request message requests to acquire the traffic parameter of each unit time interval in the preset historical time.

And the management module receives a second response message sent by the base station where the target cell is located. The second response message carries the identifier of the target cell and the traffic parameter value of the target cell in each unit time interval within the preset historical time.

Specifically, the management module may send a second request message to the base station where the target cell is located, where the second request message is used to request to acquire the traffic parameter of each unit time period within the preset historical time. The second request message carries preset historical time information.

Then, the base station where the target cell is located may send a second response message to the management module, where the second response message carries the target cell identifier and the traffic parameter value of the target cell in each unit time period within the preset historical time.

S502, the management module predicts the predicted value of the service volume of the target cell in the preset future time according to the service volume parameter value and the prediction model.

In an implementation manner, the prediction model may be an artificial intelligence algorithm model, such as an artificial intelligence algorithm model of differential Integrated Moving Average Autoregressive (ARIMA), PROPHET, Long-Short Term Memory (LSTM), neural network, and the like.

Specifically, the management module may input the initial prediction model with a traffic parameter value of each unit time period of the target cell within a preset historical time as sample data, to obtain the trained prediction model. The predictive model reflects the correspondence between the traffic volume and each unit period.

Alternatively, the initial prediction model may employ a time series prediction model.

Then, the management module may determine a traffic prediction value corresponding to each unit time interval in a preset future time based on the trained prediction model.

The preset future time is a period of time after the current moment, and the length of the preset future time can be preset in the management module.

Illustratively, the preset historical time duration is 7 × 24 hours, and the preset future time duration is 24 hours.

In the application, the management module obtains the traffic predicted value in the future time by obtaining the traffic parameter in the historical time and based on the artificial intelligence algorithm model, so that the traffic demand of the target cell in the future time can be obtained in advance, and the frame structure matched with the traffic demand in the future time can be determined, so that the traffic demand of the target cell can be met in real time.

S503, the management module determines a frame structure corresponding to the traffic predicted value based on a preset mapping rule, and determines the frame structure as a candidate frame structure.

The preset mapping rule reflects the mapping relation between the traffic predicted value and the preset frame structure type, and can be preset in the management module.

In an implementation manner, the method for determining, by a management module, a frame structure corresponding to a traffic prediction value and determining the frame structure as a candidate frame structure specifically includes:

and the management module determines a service characteristic value according to the service volume predicted value.

If the service characteristic value is in an interval, the management module determines a preset frame structure corresponding to the interval as a candidate frame structure.

For example, the preset mapping rule may be expressed as shown in table 1 below:

TABLE 1

Service characteristic value interval	First interval	Second interval	...	The Nth interval
					Identification of a Preset frame Structure	1	2	…	M

In table 1 above, the identifier of the preset frame structure corresponding to the first interval is 1, the identifier of the preset frame structure corresponding to the second interval is 2, and the identifier of the preset frame structure corresponding to the nth interval is M. And if the service characteristic value is located in the first interval, determining a preset frame structure which is corresponding to the first interval and is marked as 1 as a candidate frame structure.

Specifically, the management module may determine the service characteristic value according to the traffic prediction value. And if the service characteristic value is positioned in a certain interval, determining a certain preset frame structure corresponding to the interval as a candidate frame structure.

The traffic characteristic value is defined as an average value of a ratio of an uplink traffic predicted value and a downlink traffic predicted value corresponding to each unit time interval in a preset future time. It should be noted that the larger the service characteristic value is, the more uplink symbols are included in the corresponding candidate frame structure.

In practical applications, the service characteristic value interval may be a numerical range between 0 and 1.

In some embodiments, the [0,1] interval may be divided into L sub-intervals as traffic characteristic value intervals, which are respectively identified as a first interval [0, a ], a second interval (1/L,2/L ], … …, and an L-th interval ((L-1)/L, 1) according to a preset step size.

In still other embodiments, N +1 service characteristic value intervals may be determined according to N preset thresholds, for example, the first interval is [0, P [ ] ₁ ]The second interval is (P) ₁ ,P ₂ ]… …, the Nth interval is (P) _N ,1](ii) a Wherein, P ₁ 、P ₂ 、……P _N-1 ,、P _N Represents a plurality of preset thresholds, and satisfies 0<P ₁ <P ₂ <……<P _N <1。

The preset frame structure is a TDD system frame structure and comprises a plurality of frame structures of different types. The preset frame structure can be a frame structure defined by the existing standard of each network system, or a newly defined frame structure, and the preset frame structure information can be preset in the management module. The frame structure identification is used for representing the frame structure type, and different types of frame structures correspond to different frame structure identifications.

Illustratively, a frame structure is identified as 1, representing a first frame structure. And when the frame structure is identified as 2, the second frame structure is represented.

For any one preset frame structure, each frame comprises a plurality of symbols, and the duration of each symbol is the same. Each frame contains symbols each corresponding to a symbol type. The symbol types comprise uplink symbols, downlink symbols and special symbols. The uplink and downlink symbols are used for uplink and downlink data transmission, respectively. The special symbols do not carry out any data transmission;

the number of uplink symbols, downlink symbols, and special symbols included in different types of frame structures, and the position arrangement of each symbol in the time domain may be different. In addition, the frame lengths corresponding to different types of frame structures are the same, the symbol lengths may be different, and the symbol lengths are inversely proportional to the size of the subcarrier spacing in the frequency domain.

For example, it is assumed that the first frame structure and the second frame structure contain the same symbol length and number. A frame length is 10ms, each frame includes 10 slots, each slot includes 14 symbols, and the two frame structures are arranged in the time domain as follows:

the first frame structure: DDDSU DDSUU

The second frame structure: DDDSU

Wherein, D represents a downlink timeslot, which includes 14 downlink symbols; u represents an uplink slot, which includes 14 uplink symbols; s represents a special time slot, which sequentially includes 10 downlink symbols, 2 special symbols (the base station transceiver does not perform any data transmission within the symbol time), and 2 uplink symbols in time order.

In the application, the management module can determine the corresponding candidate frame structure according to the service characteristic value of the target cell and the preset mapping rule, so that the number of uplink and downlink symbols of the candidate frame structure is matched with the uplink and downlink traffic demands, the frame structure type is dynamically configured according to the traffic demands, and the uplink and downlink traffic demands of the target cell can be simultaneously met.

In an embodiment, with reference to fig. 4 and as shown in fig. 6, before the acquiring, by the management module, an association frame structure of an associated cell adjacent to the target cell, the method further includes:

s601, the management module determines at least one target adjacent cell adjacent to the target cell.

The target adjacent cell is at least one adjacent TDD cell corresponding to the target cell, and the base station where the target cell is located in the signal coverage area of the adjacent cell.

S602, if the target adjacent cell meets the preset association condition, the management module determines the target adjacent cell as an associated cell.

Wherein the preset association condition comprises at least one of the following items: and the distance between the base station of the target adjacent cell and the base station of the target cell is smaller than a preset distance threshold value. Or the average value of the signal intensity of the target adjacent cell in the preset time is greater than the preset intensity threshold value.

In an implementation manner, when the management module determines the target neighboring cell as the associated cell, the associated cell may be determined according to the latitude and longitude information of the base station.

Specifically, after determining at least one target neighboring cell of the target cell, if the distance between the base station where the target neighboring cell is located and the base station where the target cell is located is smaller than a preset distance threshold, the management module determines the target neighboring cell as the associated cell of the target cell.

The distance between the base station of the target cell and the base station of at least one target adjacent cell can be calculated according to the longitude and latitude information of each base station, and the longitude and latitude information of the base stations is preset in the management module.

In another implementation manner, when the preset association condition is: when the average value of the signal strengths of the target neighboring cells within the preset time is greater than the preset strength threshold, if the target neighboring cells satisfy the preset association condition, the method for determining the target neighboring cells as the associated cells by the management module specifically includes:

and the management module sends a third request message to the base station where the target cell is located. The third request message is used for requesting to acquire the information of the associated cell.

And the management module receives a third response message sent by the base station where the target cell is located. And the third response message carries the identification of the target cell and the identification of the associated cell. And the third response message is sent after the base station where the target cell is located determines that the target adjacent cell is the associated cell of the target cell. The associated cells are: and after the base station where the target cell is located measures the signal intensity of at least one target adjacent cell, the average value of the signal intensity in the preset time is larger than the target adjacent cell of a preset first threshold value.

Specifically, the management module sends a third request message to the base station where the target cell is located, where the third request message is used to request to acquire information of a cell associated with the target cell; the third request message carries the identifier of the target cell.

Then, the base station of the target cell measures the signal strength of each neighboring cell.

And if the average value of the signal intensity of a certain adjacent cell in the preset time is greater than a preset first threshold value, determining the adjacent cell as the associated cell of the target cell.

Wherein, the signal strength of the adjacent cell can be defined as the receiving level of the reference signal; and the base station of the target cell measures the signal intensity of each adjacent cell in each unit time interval according to a preset period, and calculates the average value of the signal intensity in preset time.

Then, the base station where the target cell is located may send a third response message to the management module, where the third response message carries the identifier of the target cell and the identifier of the associated cell.

And the management module receives a fourth response message sent by the base station where the target cell is located. And the fourth response message carries the identification of the target cell and the identification of the associated cell. And the fourth response message is sent after the base station where the target cell is located determines that the target adjacent cell is the associated cell of the target cell. The associated cells are: and the base station of the target cell determines at least one measuring terminal of the target cell, and obtains a target adjacent cell of which the average value of the signal strength is greater than a preset third threshold value after a measurement report of the at least one measuring terminal in a preset time is obtained. And the at least one measuring terminal is a terminal accessed to the target cell, and the average value of the signal intensity of the target cell measured by the at least one measuring terminal in the preset time is greater than a preset second threshold value. The measurement report carries the identifier and the signal strength measurement value of at least one target neighboring cell measured by at least one measurement terminal. The signal strength measurement value is an average value of a plurality of signal strength values measured by at least one measuring terminal within a preset time.

Then, the base station of the target cell determines at least one measuring terminal of the target cell.

The measuring terminal is a terminal accessed to the target cell, and the average value of the signal intensity of the target cell measured by the measuring terminal in the preset time is greater than a preset second threshold value.

Then, the base station of the target cell acquires the measurement report of each measurement terminal within the preset time.

The measurement report carries the identifier and the signal strength measurement value of each neighboring cell measured by the terminal. The signal strength measurement value of the adjacent cell is an average value of a plurality of signal strength values measured by the terminal within a preset time.

And if the signal intensity average value of the target adjacent cell is greater than a preset third threshold value, determining the target adjacent cell as the associated cell of the target cell. The signal strength average value of the target adjacent cell is the average value of the signal strength measured values measured by each measuring terminal.

Then, the base station where the target cell is located may send a fourth response message to the management module, where the fourth response message carries the target cell identifier and the associated cell identifier.

In the present application, if the candidate frame structure is inconsistent with the frame structure currently configured in the target cell, which indicates that the frame structure currently configured in the target cell does not meet the uplink and downlink traffic demand of the cell in the future time, the target frame structure meeting the uplink and downlink traffic and traffic performance requirements in the future time needs to be determined for the target cell.

In order to avoid interference among cells supporting different frame structures, the method and the device for determining the frame structure of the target cell can determine the associated cell corresponding to the target cell before determining the target frame structure of the target cell. By determining as the associated cell a neighbouring cell which is at a small distance from the target cell or whose signal coverage area includes the base station where the target cell is located, a neighbouring cell which is potentially interfering with the target cell can be identified. And determining different frame structures as the target frame structure of the target cell according to whether the candidate frame structure of the target cell is the same as the frame structure of the associated cell.

In an embodiment, referring to fig. 6, as shown in fig. 7, in the above S403, the determining, by the management module, the time domain position and the symbol type of the interference symbol in the associated frame structure and the candidate frame structure includes:

s701, the management module divides the frame length into a plurality of grids with continuous time domains.

Wherein the length of each grid is the same. Each grid corresponds to a time-domain position in the frame structure and a symbol located at a time-domain position. The length of each grid is determined according to the frame structure type of the associated frame structure, or, alternatively, the frame structure type of the candidate frame structure. The associated frame structure is a frame structure currently configured for the associated cell.

In an implementation manner, the management module may divide the frame length into a plurality of time-domain continuous grids, and the length of each grid is the same; each grid corresponds to a time-domain position in the frame structure and to a symbol located at that time-domain position.

The length of the grid can be determined according to the frame structure type supported by each base station in the preset area.

Optionally, the length of the grid is a minimum value of symbol lengths corresponding to each frame structure in the preset region.

Illustratively, the preset region includes a first frame structure and a second frame structure, the corresponding frame lengths are 10ms, the corresponding symbol lengths are 71.35us and 35.68us respectively, the length of the grid is 35.68us, the number of the corresponding grids is 280(10ms/35.68us), and the corresponding grid identifications are 1, 2, 3, … … and 280 respectively.

The correspondence of the grid to the symbols in the frame structure is shown in table 2 below:

TABLE 2

Taking grid 1 as an example, grid 1 corresponds to symbol 1 and symbol 2 in the first frame structure, and corresponds to symbol 1 in the second frame structure.

S702, corresponding to the time domain position of the interference grid, when the symbol type of the associated frame structure is an uplink symbol and the symbol type of the candidate frame structure is a downlink symbol, or the symbol type of the associated frame structure is a downlink symbol and the symbol type of the candidate frame structure is an uplink symbol, the management module determines the target grid as the interference grid.

Wherein the target grid is any one of the grids.

Specifically, if the symbol type of the associated frame structure is an uplink symbol and the symbol type of the candidate frame structure is a downlink symbol, or the symbol type of the associated frame structure is a downlink symbol and the symbol type of the candidate frame structure is an uplink symbol, corresponding to a certain trellis (i.e., a target trellis), the trellis is determined as an interference trellis.

Illustratively, assume 10ms per frame, containing several slots, each slot containing 14 symbols; d represents a downlink time slot, U represents an uplink time slot, and S represents a special time slot; d. u and s respectively represent a downlink symbol, an uplink symbol and a special symbol; slot D contains 14 downlink symbols; the time slot U comprises 14 uplink symbols; the slot S contains 10 downlink symbols, 2 special symbols (the base transceiver station does not transmit any data during the symbol time), and 2 uplink symbols.

If the symbol length of the associated frame structure is 71.35us, the associated frame structure comprises 140 symbols and 10 time slots; if the symbol length of the candidate frame structure is 35.68us, the candidate frame structure contains 280 symbols, 20 slots.

The associated frame structure is: DDDSU DDSUU

The candidate frame structure is: DDDDDDSSUU DDDDDDDDSSUU

Taking the example of the trellis identified as 225-252, the trellis corresponds to the 9 th slot (slot U) of the associated frame structure and to the 17 th to 18 th slots (both S slots) of the candidate frame structure.

Wherein the prediction model reflects the correspondence between the traffic type parameter value and each unit time interval.

Alternatively, the initial prediction model may be a time series prediction model, such as ARIMA, prophen, LSTM, etc.

Then, the management module may determine a predicted value of the service type parameter of the target cell corresponding to each unit time interval in a preset future time based on the trained prediction model.

S803, the management module determines a service type parameter predicted value of the associated cell in the preset future time according to the service type parameter value of the associated cell.

Wherein the prediction model reflects a correspondence between the traffic type parameter value and each unit time period.
