Description

Frame structure configuration method, device and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a frame structure configuration method, a device, and a storage medium.

Background

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

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

For ease of understanding the present application, relevant elements referred to in the present application will now be described.

Frame structure

In a mobile communication system, data is transmitted in units of frames over a wireless air interface, and one frame is one data transmission period. According to the protocol, each network system has a corresponding standardized frame structure, and the frame structures corresponding to different network systems 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. Symbol types can be classified into uplink symbols, downlink symbols, and special symbols. The uplink and downlink symbols are used for data transmission in the uplink and downlink, respectively. The special symbol does not perform any data transmission.

For a TDD system, uplink and downlink data are transmitted in a time division multiplexing manner in the same data frame. One frame contains uplink symbols, downlink symbols and special symbols. The frame structures of different types may include different arrangements of uplink symbols, downlink symbols, and the number of special symbols, and the positions of the symbols in the time domain.

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

The 5G support is shown as 240KHz for the largest subcarrier spacing, 4.46us for the smallest symbol length, 2240 symbols per frame. The minimum subcarrier spacing is 15KHz and the corresponding maximum symbol length is 71.35us, with 140 symbols per frame.

For a certain subcarrier spacing, the 5G TDD system may 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 in different areas as two different types of frame structures as follows:

first frame structure: DDDSU DDSUU

Second frame structure: DSUUU

Wherein, a frame comprises 10 time slots, D represents a downlink time slot, and 14 downlink symbols are included; u represents an uplink time slot, which contains 14 uplink symbols; s represents a special slot in which 10 downlink symbols, 2 special symbols (the base transceiver station does not transmit any data during the symbol time), and 2 uplink symbols are sequentially included in chronological order.

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

For example, in the 2C scenario, the service requirement is mainly downlink service, and the TDD cell is configured as a frame structure (first frame structure) with a relatively large number of downlink symbols; the 2B scenario is mainly configured as a frame structure (second frame structure) with a relatively large number of uplink symbols.

For the TDD system, supporting multiple frame structures is beneficial to flexibly meeting the service requirements of different scenarios, but in general, it is required to keep the 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 cell performance is affected.

For example, 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 uplink and downlink cross interference on the cell performance, the interference is generally reduced by manually setting an isolation region (i.e., increasing the spatial distance between base stations supporting different frame structures when the base stations are deployed, and setting an isolation region between two base stations). However, this approach affects the continuity of signal coverage and affects the interference suppression effect.

In view of the above problems, an embodiment of the present application provides a frame structure configuration method, after obtaining a candidate frame structure of a target cell and an associated frame structure of an associated cell adjacent to the target cell, if the associated frame structure is different from the candidate frame structure, determining a time domain position and a symbol type of an interference symbol in the associated frame structure and the candidate frame structure, and determining 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, a traffic volume predicted value and a traffic type parameter predicted value of the target cell, and a traffic volume predicted value and a traffic type parameter predicted value of the associated cell. In this way, the inter-cell interference supporting different frame structures can be reduced by adjusting the frame structure, the service performance requirement of the cell is met, and the technical problem of low interference suppression effect in the general technology is solved.

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

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

The preset 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, i.e. cell 1 and cell 2 are both 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 can be located in a certain base station, core network equipment and a base station operation maintenance platform in a preset area or can be located in independent physical equipment.

Alternatively, the base station may be a base station or a base station controller for wireless communication, or the like.

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 acquires a candidate frame structure of the target cell.

In one implementation, the target cell may measure the traffic parameter corresponding to each unit period according to a preset period. The management module may then obtain the traffic parameter values of the target cell during any period (e.g., 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 period length is the same as the unit period length. The traffic parameters include uplink traffic and downlink traffic, which may be defined as one or a combination of both of uplink and downlink PRB resource utilization or data traffic, respectively.

Illustratively, the unit time period is 5 minutes in length.

In another implementation manner, the frame structure of the TDD system in the general technology is preconfigured, and cannot be dynamically adjusted based on the change condition of the uplink and downlink service 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 history time, and then predict, based on the artificial intelligence algorithm model, 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.

In this way, the management module dynamically determines the target frame structure in the preset future time according to the traffic prediction value of the target cell and the inter-cell interference condition supporting different frame structures so as to adaptively match the uplink and downlink traffic demands, thereby solving the technical problem that the general technology is difficult to meet the different uplink and downlink traffic demands 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 the currently configured frame structure of the associated cell.

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

In one implementation manner, the method for obtaining the association frame structure of the association cell adjacent to the target cell by the management module 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 currently configured frame structure of the associated cell. The first request message carries the identification of the associated cell.

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

The management module determines the frame structure corresponding to the identification of the currently configured frame structure of the associated cell as the associated frame structure.

Specifically, when the management module obtains the associated frame structure of the associated cell adjacent to the target cell, a first request message may be sent to the base station where the associated cell is located, where the first request message is used to request to obtain the currently configured frame structure of the associated cell. The first request message carries an associated cell identifier. The base station where the associated cell is located may then send a first response message to the management module. The first response message carries the associated cell identifier and the currently configured frame structure identifier of the associated cell.

The execution order of S401 and S402 is not limited in this application. The management module may execute S401 first and then S402; s402 may be executed first, and S401 may be executed later; 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 candidate frame structure of the target cell is different from the frame structure of the associated cell, it is indicated that uplink and downlink cross interference will occur between the target cell and the associated cell. In this case, the management module can determine the time domain position and the symbol type of the interference symbol in the associated frame structure and the candidate frame structure of the target cell according to the relation between the frame structure of the associated cell and the candidate frame structure of the target cell, so that the subsequent interference avoidance in the mode of adjusting 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 is facilitated, and the service performance of the cell is ensured.

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 within 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 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 to the candidate frame structure, no interference exists between the target cell and the associated cell, and the candidate frame structure is determined to be the target frame structure. 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 the candidate frame structure of the target cell or the frame structure of the 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 volume predicted value and the traffic type parameter predicted value of the target cell, and the traffic volume predicted value and the traffic type parameter predicted value of the associated cell.

In one implementation, 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 of 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, since data transmission and reception are not performed in the silent symbol time, the strategy of adjusting the uplink and downlink symbols in the frame structure to silent symbols may result in a decrease in the number of symbols available for uplink and downlink data transmission, affecting the service transmission delay and rate of the cell.

In this case, the management module may consider the traffic prediction value and the traffic type parameter prediction value in determining the silence symbol. Only when the traffic volume predicted value and the traffic type parameter predicted value meet the preset condition, namely the cell has smaller traffic volume in the preset future time and the low-delay traffic and the high-speed traffic occupy smaller time, the interference symbol is determined as the silence symbol. In this way, the management module determines the silence symbol according to the traffic volume 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, so that the inter-cell interference can be avoided, the influence of the frame structure adjustment on the traffic performance of the cell can be avoided, and the adjusted frame structure can simultaneously meet the traffic volume and the traffic performance requirements of the cell.

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

and when the symbol type of the candidate frame structure is a downlink symbol and the target cell meets the 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 so as to obtain an adjusted candidate frame structure.

The preset conditions comprise: the traffic prediction value is less than a preset traffic threshold and the traffic type parameter prediction value is less than a preset percentage threshold.

And when the symbol type of the candidate frame structure is a downlink symbol and 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, so as to obtain the adjusted associated frame structure.

And corresponding to the time domain position of the interference grid, and determining the interference grid as a collision grid when the symbol type of the candidate frame structure is a downlink symbol or an uplink symbol and neither the target cell nor the associated cell meets a preset condition.

In the present application, if the frame structure of the candidate frame of the target cell is different from the frame structure of the associated cell, the management module may determine, according to the relationship between the frame structure of the associated cell and the frame structure of the candidate frame of the target cell, a symbol position where uplink and downlink cross interference exists between the target cell and the associated cell, thereby determining an interference grid. Subsequently, by adjusting the candidate frame structure of the target cell or the associated frame structure of the associated cell, the symbol corresponding to the interference grid is determined to be a silent symbol, so that interference avoidance is realized, and the service performance of the target cell and the associated cell can be ensured.

In addition, since data is not transmitted and received in the silent symbol time, the adjustment of the uplink and downlink symbols in the frame structure to the silent symbols will reduce the number of symbols available for uplink and downlink data transmission, affecting the service transmission delay and rate of the cell.

In this case, the management module considers traffic and traffic type parameter predictors when determining silence symbols. And determining the symbol corresponding to the interference grid as a silent symbol only when the predicted value of the traffic and the traffic type parameter meets the preset condition, namely, the cell has smaller traffic in the preset future time and the occupation ratio of the low-delay traffic to the high-speed traffic is smaller, otherwise, determining the grid as a conflict grid.

In this way, the management module determines the silence symbol according to the traffic 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, so that the inter-cell interference can be avoided, the influence of the frame structure adjustment on the traffic performance of the cell can be avoided, and the adjusted frame structure can simultaneously meet the traffic and the traffic performance requirements of the cell.

In one implementation, before determining the target frame structure of the target cell and the target frame structure of the associated cell, the management module further includes:

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. 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. The sixth response message carries the identification of the target cell and the identification of the currently configured frame structure of the target cell.

If the number of conflict grids in the candidate frame structure or the associated frame structure is larger than a preset percentage threshold, determining the currently configured frame structure of 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.

If the candidate frame structure and the conflict grid number in the associated frame structure are not more than the preset percentage threshold, the adjusted candidate frame structure is determined to be the target frame structure of the target cell, and the adjusted associated frame structure is determined to be the target frame structure of the associated cell.

Wherein the conflict grid number duty ratio is the ratio of the conflict grid number to the total number of grids.

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

The conflict grids are used for indicating the time domain positions where the interference exists among the cells supporting different frame structures, the number of the conflict grids occupies a large amount, which indicates that the interference among the cells supporting different frame structures is serious, so that in order to avoid the influence on the service performance of the cells, 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 conflict grids are more, and keep the frame structure of each cell unchanged in the preset future time so as to ensure the service performance of each cell.

and the management module acquires the traffic parameter value of the associated cell within the preset historical time.

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

Specifically, the management module may input the traffic parameter value of each unit period of the associated cell in a preset historical time as sample data into an initial prediction model to obtain a 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 description of the prediction model in S502, which is not repeated here.

In one implementation manner, the method for obtaining the traffic parameter value of the associated cell by the management module in the preset history time specifically includes:

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 period within a preset history 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 identification of the associated cell and the traffic parameter value of each unit time period of the associated cell in 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 obtain a traffic parameter of each unit period in a preset history 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 each unit period of time of the associated cell in a preset history time.

In one embodiment, referring to fig. 4, as shown in fig. 5, in S401, a method for obtaining a candidate frame structure of a target cell by a management module specifically includes:

S501, the management module acquires the traffic parameter value of the target cell within the preset history time.

In one implementation manner, the method for obtaining the traffic parameter value of the target cell by the management module in the preset history 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 parameters of each unit time period within 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 identification of the target cell and the traffic parameter value of each unit time period of the target cell in 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 obtain the traffic parameter of each unit period in the preset history 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 period within a preset history time.

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

In one implementation, the predictive model may be an artificial intelligence algorithm model, such as a differential integrated moving average autoregressive model (Autoregressive Integrated Moving Average model, ARIMA), PROPHET, long Short-Term Memory (LSTM), neural network, or the like.

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

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

The management module may then determine a traffic prediction value corresponding to each unit period within a preset future time based on the trained prediction model.

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

Illustratively, the predetermined historical time length is 7 x 24 hours and the predetermined future time length is 24 hours.

In the method, the management module obtains the traffic forecast value in the future time based on the artificial intelligence algorithm model by obtaining the traffic parameter in the history time, and can acquire the traffic demand of the target cell in the future time in advance, so that the frame structure matched with the traffic demand in the future time can be determined, and 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 prediction value based on a preset mapping rule, and determines the frame structure as a candidate frame structure.

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

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

the management module determines a traffic characteristic value according to the traffic prediction value.

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

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

TABLE 1

Business characteristic value interval	A first section	A second interval	...	Nth interval
					Presetting the identification of a frame structure	1	2	…	M

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

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

Wherein, the traffic characteristic value is defined as the average value of the ratio of the uplink traffic prediction value to the downlink traffic prediction value corresponding to each unit time period in the preset future time. The larger the service characteristic value is, the larger the number of uplink symbols included in the corresponding candidate frame structure is.

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 subintervals according to a preset step size, and the L subintervals 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].

In still other embodiments, n+1 service characteristic value intervals may be determined according to preset N thresholds, for example, the first interval is [0, p ₁ ]The second interval is (P ₁ ,P ₂ ]… … the N-th interval is (P _N ,1]The method comprises the steps of carrying out a first treatment on the surface of the Wherein P is ₁ 、P ₂ 、……P _N-1 ,、P _N Representing a plurality of preset thresholds, satisfying 0<P ₁ <P ₂ <……<P _N <1。

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

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

For any preset frame structure, each frame comprises a plurality of symbols, and the duration of each symbol is the same. Each symbol contained in each frame corresponds to a symbol type. The symbol types include uplink symbol, downlink symbol, and special symbol. The uplink and downlink symbols are used for data transmission in the uplink and downlink, respectively. Special symbols do not perform any data transmission;

the frame structures of different types may include different arrangements of uplink symbols, downlink symbols, and the number of special symbols, and the positions of the symbols in the time domain. 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 subcarrier spacing sizes in the frequency domain.

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

first frame structure: DDDSU DDSUU

Second frame structure: DDDSU

Wherein D represents a downlink slot, which includes 14 downlink symbols; u represents an uplink time slot, which contains 14 uplink symbols; s represents a special slot in which 10 downlink symbols, 2 special symbols (the base transceiver station does not transmit any data during the symbol time), and 2 uplink symbols are sequentially included in chronological 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 one embodiment, in conjunction with fig. 4, before the management module obtains the association frame structure of the association cell adjacent to the target cell, as shown in fig. 6, 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 association cell.

Wherein the preset association condition comprises at least one of the following: 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. Or the average value of the signal intensity of the target adjacent cell in the preset time is larger than a preset intensity threshold value.

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

Specifically, after determining at least one target neighboring cell of the target cell, the management module determines the target neighboring cell as an associated cell of the target cell if a distance between a 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 distance between the base station where the target cell is located and the base station where at least one target adjacent cell is located can be calculated according to longitude and latitude information of each base station, and the longitude and latitude information of the base station is preset in the management module.

In yet another implementation, when the preset association condition is: when the average value of the signal intensities of the target adjacent cells in the preset time is larger than a preset intensity threshold value, if the target adjacent cells meet preset association conditions, the method for determining the target adjacent cells as the associated cells by the management module specifically comprises the following steps:

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 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. 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: 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 the preset first threshold value.

Specifically, the management module sends a third request message to the base station where the target cell is located, and the third request message is used for requesting to acquire information of an associated cell of the target cell; the third request message carries the identification of the target cell.

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

If the average value of the signal intensity of a certain adjacent cell in the preset time is larger than a preset first threshold value, the adjacent cell is determined to be the associated cell of the target cell.

Wherein, the signal strength of the adjacent cell can be defined as the reference signal receiving level; and the base station of the target cell measures the signal intensity of each adjacent cell in each unit time period 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. 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: the base station of the target cell determines at least one measuring terminal of the target cell, and obtains a measurement report of the at least one measuring terminal within a preset time, and then the average value of the signal strength is larger than a preset third threshold value. The at least one measurement 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 measurement terminal in the preset time is larger than a preset second threshold value. The measurement report carries the identification and the signal strength measurement value of at least one target adjacent 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 measurement terminal in a preset time.

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

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

And then, the base station where the target cell is located acquires a measurement report of each measurement terminal in a preset time.

The measurement report carries the identifiers of the adjacent cells and the signal strength measured values measured by the terminal. The signal strength measured value of the adjacent cell is an average value of a plurality of signal strength values measured by the terminal in a preset time.

If the signal intensity mean value of the target adjacent cell is larger than a preset third threshold value, determining the target adjacent cell as an associated cell of the target cell. The average value of the signal intensity of the target adjacent cell is the average value of the signal intensity measured values measured by all the measuring terminals.

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

In order to avoid interference among cells supporting different frame structures, the method and the device can determine the associated cell corresponding to the target cell before determining the target frame structure of the target cell. By determining, as an associated cell, a neighboring cell having a small inter-cell distance from the target cell or a signal coverage area including the base station where the target cell is located, a potential neighboring cell having interference with the target cell can be identified. And determining the 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 one embodiment, referring to fig. 6, as shown in fig. 7, in S403, the management module determines a time domain position and a symbol type of the interference symbol in the association frame structure and the candidate frame structure, including:

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

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 based on the frame structure type of the associated frame structure, or the frame structure type of the candidate frame structure. The associated frame structure is the currently configured frame structure of the associated cell.

In one implementation, the management module may divide the frame length into a plurality of time-domain continuous grids, each of which has the same length; each grid corresponds to a time domain position in the frame structure and a symbol located at the 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 the minimum value in the symbol lengths corresponding to the frame structures in the preset area.

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

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 of the first frame structure, and corresponds to symbol 1 of 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 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 grid (i.e., the target grid), the grid is determined to be an interference grid.

By way of example, assume that 10ms per frame contains 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; time slot D contains 14 downlink symbols; the time slot U contains 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 DDDDDDSSUU

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

The symbol types of the associated frame structure and the candidate frame structure corresponding to the grid are shown in the following table 3:

TABLE 3 Table 3

Corresponding to grids 225-234 and 239-248, the symbol types of the candidate frame structures are all downlink symbols (d), the symbol types of the associated frame structures are all uplink symbols (u), and then the grids are all interference grids.

Corresponding to grids 235-238, 249-252, the candidate frame structure and the symbol type of the associated frame structure are both uplink symbols (u) or special slots(s), and neither the grids belong to an interference grid.
