1. Dragon-primary lens antenna

A lens antenna is an antenna capable of obtaining a pencil-shaped, fan-shaped or other beam by converting spherical waves or cylindrical waves of a point source or line source into plane waves by electromagnetic waves. The luneberg lens is a lens, as shown in fig. 1, fig. 1 is a schematic structural diagram of a luneberg lens diverging electromagnetic wave, the luneberg lens is a complete spherical lens, electromagnetic wave emitted by a feed source can be converted into plane wave for emission through refraction of the luneberg lens, and three-dimensional layering multibeam can be rapidly realized by adjusting the position of the feed source and increasing the number of the feed sources.

The divergent beams generated by the electromagnetic wave feed source after passing through the Longber lens are shown in figure 2, and the divergent beams of multiple channels of electromagnetic waves can be generated by passing through the Longber lens, so that the overlapping among all sub beams is less, the anti-interference capability is strong, the beams are mainly divergent in the horizontal direction, and the directivity is strong. The electromagnetic wave conversion rate of the traditional base station antenna is about 70%, and the conversion efficiency of the Robert lens can be up to more than 90%.

The Robert lens antenna has the characteristics of high gain, wide vertical beam, multiple beams and the like, is suitable for high-speed rails, highways, super bridge linear scenes, remote rural punctiform scenes and near-sea ultra-far coverage scenes, and can achieve the advantages of coverage and cost. The multi-beam lens antenna is applied to communication service scenes such as urban capacity expansion and cell deep coverage of a communication system, and the signal coverage area of the communication network system can be enlarged by deployment of the multi-beam lens antenna, so that the spectrum utilization rate is improved.

However, due to the existence of denser high-rise cells and office buildings in cities, reflection generated between city buildings may destroy the excellent directivity and small sidelobe interference characteristics of the lens antenna in open scenes. Meanwhile, due to the fact that the cells are relatively close to each other, strong signal interference is formed in the overlapping area of the adjacent cells due to the fact that signals of the different cells possibly form strong signal interference due to the influence of strong reflected waves and refraction waves of signals of the adjacent cells, and therefore performance of the lens antenna cells is affected. In order to ensure the communication service experience of the user, how to ensure the signal quality of the serving cell under the condition of generating signal interference is a technical problem to be solved in the present technology.

In order to solve the above technical problems, the present disclosure provides a method, an apparatus, and a storage medium for determining the number of transmitting ports, which are used for solving the technical problem of how to guarantee the signal quality of a serving cell under the condition of generating signal interference.

The target adjacent cell 301b is the adjacent cell with the same network configuration as the target signal overlapping cell 301a in the adjacent cells of the target signal overlapping cell 301 a; and after determining the target signal overlapping cell 301a and the target neighbor cell 301b in the lens antenna cell, determining the number of transmitting ports corresponding to each first type terminal in the target signal overlapping cell 301a based on the signal strength of the first type terminal accessing the target signal overlapping cell 301 a.

As shown in fig. 5, fig. 5 is a diagram illustrating a method for determining the number of transmitting ports according to an embodiment of the present disclosure, and the method may be applied to the apparatus for determining the number of transmitting ports shown in fig. 4, and the method includes the following steps S501 to S502, which are described in detail below.

S501, a transmitting port number determining device determines a target signal overlapping cell in a preset area.

The target signal overlapping cell is a cell in which the duty ratio of a second type terminal accessing the target signal overlapping cell in a first type terminal accessing the target signal overlapping cell is smaller than a first preset threshold value, and the duty ratio of a third type terminal accessing the target signal overlapping cell in the first type terminal accessing the target signal overlapping cell is smaller than a second preset threshold value; the signal intensity of the neighbor cell measured by the first type terminal is larger than the signal intensity of the serving cell, the signal intensity of the serving cell measured by the second type terminal is smaller than a third preset threshold, and the signal intensity of the serving cell measured by the third type terminal is larger than a fourth preset threshold.

In a possible implementation manner, the transmitting port determining means instructs the base station of the cell in the preset area to transmit a synchronization signal block (Synchronization Signal Block, SSB) signal, so that the terminal in the preset area performs signal strength measurement, and the transmitting port determining means determines the first type of terminal, the second type of terminal, and the third type of terminal based on the signal strength measurement report.

The first preset threshold is 60%, the second preset threshold is 70%, and the transmitting port number determining means determines that a cell of a certain cell within the preset area is a target signal overlapping cell when the duty ratio of the second type terminal of the first type terminals is less than 60% and the duty ratio of the third type terminals of the first type terminals is less than 70%.

It can be understood that the duty ratio of the second type of terminal with the signal strength smaller than the third preset threshold in the first type of terminal accessed in the target signal overlapping cell is smaller than the first preset threshold, and the duty ratio of the third type of terminal with the signal strength larger than the fourth preset threshold in the first type of terminal accessed in the target signal overlapping cell is smaller than the second preset threshold, that is, the target signal overlapping cell is a target signal overlapping cell with a close duty ratio of a coverage overlapping region with stronger signal strength and a coverage overlapping region with weaker signal strength.

S502, the transmitting port number determining device determines the transmitting port number corresponding to each first type terminal based on the signal strength of the first type terminal accessing the target signal overlapping cell.

The target adjacent cell is the adjacent cell which has the same network configuration with the target signal overlapping cell in the adjacent cells of the target signal overlapping cell; the number of the transmitting ports is the number of the ports of the joint transmission of the target signal overlapping cell and the target adjacent cell to the first type terminal, and the number of the transmitting ports is in direct proportion to the average signal intensity.

It will be appreciated that a neighbor cell may act as a co-cell for joint transmission when its network configuration is the same as that of the target signal overlay cell.

It will be appreciated that the larger the duty cycle of the second type of terminals in the first type of terminals to which the target signal overlap cell is connected, the higher the signal strength of the target signal overlap cell. Under the condition that the signal quality of the target signal overlapping cell is strong, the number of ports of joint transmission is determined according to the duty ratio of the overlapping area with strong signal strength, the number of ports of joint transmission is increased, the transmission is carried out with a plurality of ports, the coverage area of the signal and the capacity of data transmission are improved, and the signal quality of the signal transmitted by the ports is ensured.

The technical scheme provided by the embodiment at least has the following beneficial effects: the transmitting port number determining device in the present disclosure firstly determines a target signal overlapping cell in a preset area; the target signal overlapping cell is a cell in which the duty ratio of a second type of terminals in the accessed first type of terminals is smaller than a first preset threshold value and the duty ratio of a third type of terminals in the first type of terminals is smaller than a second preset threshold value; the signal intensity of the neighbor cell measured by the first type terminal is larger than the signal intensity of the service cell, the signal intensity measured by the second type terminal is smaller than a third preset threshold, and the signal intensity measured by the third type terminal is larger than a fourth preset threshold; namely, a target signal overlapping cell which generates an overlapping area in a preset area and has a similar duty ratio of the overlapping area with stronger signal strength to the overlapping area with weaker signal strength is determined. Then determining the number of transmitting ports corresponding to each first type terminal based on the signal intensity of the first type terminal accessed into the target signal overlapping cell, wherein the target adjacent cell is the adjacent cell with the same network configuration as the target signal overlapping cell in the adjacent cells of the target signal overlapping cell; the number of the transmitting ports is the number of the ports of the joint transmission of the target signal overlapping cell and the target adjacent cell to the first type terminal, and the number of the transmitting ports is in direct proportion to the average signal intensity. Under the condition that the coverage overlapping area with stronger signal strength is determined to be similar to the coverage overlapping area with weaker signal strength, the number of ports of joint transmission is determined according to the signal strength of each first type terminal, the first type terminal with stronger signal strength improves the number of ports of joint transmission, the transmission is performed with more ports, the coverage area of the signal and the capacity of data transmission are improved, the signal strength of the transmitted signal is ensured, the first type terminal with weaker signal strength reduces the number of ports of joint transmission, the transmission is performed with fewer ports, and channel resources are distributed by fewer ports, so that the signal strength of the transmitted signal is ensured, namely the signal quality of the joint transmission is ensured under the condition of generating signal interference.

In a possible implementation manner, as shown in fig. 6 in connection with fig. 5, the above-mentioned process of determining the target signal overlapping cells in the preset area by using the transmitting port number determining device in S501 may be implemented specifically by the following S601-S606, which will be described in detail below.

S601, the transmitting port number determining device receives a measurement report of at least one preset terminal.

In a possible implementation manner, as shown in fig. 7 in conjunction with fig. 6, before the determining device of S604 determines that, in the first type of terminal, the average value of the measured signal strength of the serving cell and the signal strength of the target neighbor cell is greater than the second preset threshold is the second type of terminal, it is further required to determine the target neighbor cell in the neighbor cell of the serving cell, and this process may be implemented in the following steps S701-S702, which are described in detail below:

s701, the transmitting port number determining device obtains the network configuration of the service cell, and the network configuration and the PRB utilization rate of each adjacent cell of the service cell.

In a possible implementation manner, the transmitting port number determining device may obtain the service cell and the identifier of each neighboring cell of the service cell through a measurement report, and obtain the network configuration and the PRB utilization rate of each neighboring cell of the service cell from the service cell and the base station of the neighboring cell based on the service cell and the identifier of each neighboring cell of the service cell.

In one possible implementation, the network configuration information includes, but is not limited to, at least one of: frequency band, uplink and downlink frequency point, uplink and downlink bandwidth, subcarrier interval, time slot ratio, cyclic prefix length and uplink and downlink shared channel configuration.

S702, the transmitting port number determining device determines that the neighbor cell with the PRB utilization ratio greater than a fifth preset threshold is a target neighbor cell in the neighbor cells of the serving cell, wherein the network configuration of the neighbor cells is the same as that of the serving cell.

The transmitting port number determining device determines the frequency band, uplink and downlink frequency points, uplink and downlink bandwidths of the neighbor cells of the serving cell, the subcarrier interval, the time slot ratio, the cyclic prefix length and the uplink and downlink shared channel configuration, and determines that the frequency band, the uplink and downlink frequency points, the uplink and downlink bandwidths, the subcarrier interval, the time slot ratio, the cyclic prefix length and the uplink and downlink shared channel configuration of the neighbor cells are the same, and the neighbor cells with the PRB utilization ratio greater than 60% are the target neighbor cells.

The technical scheme provided by the embodiment at least has the following beneficial effects: the transmitting port number determining device obtains the network configuration of the serving cell, the network configuration of each neighbor cell of the serving cell and the physical resource block PRB utilization rate through the measurement report, and determines that a target neighbor cell which is the same as the network configuration of the serving cell and has low physical resource block PRB utilization rate is a collaborative cell for joint transmission.

In a possible implementation manner, as shown in fig. 7, the process of determining the number of transmitting ports corresponding to each first type of terminal by the transmitting port number determining device based on the signal strength of the first type of terminal accessing the target signal overlapping cell as shown in fig. 8 may be specifically implemented by the following S801-S803, which will be described in detail below.

S801, the transmitting port number determining device determines the product of the maximum combinable transmitting port number and the preset proportion as a sixth preset threshold.

The maximum combinable transmitting port number is the minimum value of the configurable port number of the target signal overlapping cell and the configurable port number of the target adjacent cell.

In a possible implementation, the preset proportion is a preset proportion determined based on the target signal overlapping cell scene.

In one possible implementation, the current joint transmission supports a maximum of 32 antenna ports, and the number of configurable ports of the joint transmission may be 1, 2, 4, 8, 12, 16, 24, and 32.

The preset proportion is one half, and the transmitting port number determining device determines one half of the maximum combinable transmitting port number of the target signal overlapping cell as a sixth preset threshold.

S802, the transmitting port number determining device determines the transmitting proportion of the joint transmitting port number based on the average signal intensity of the first type terminal in a preset time period.

Wherein the transmission ratio is proportional to the average signal strength of the first type of terminal in a preset time period.

It can be understood that the stronger the average signal strength of the first type terminal in the preset time period is, the stronger the signal strength of the target signal overlapping cell is, at this time, the transmitting proportion of the ports needs to be improved, and the signals are transmitted with a larger number of ports, so that the signal coverage area and the data transmission quantity are enlarged, and the signal quality is improved.

S803, the transmitting port number determining device determines the number of the combined transmitting ports based on the product of the sixth preset threshold and the transmitting proportion.

In a possible implementation, the signals are jointly transmittedNumber of antenna ports P _set The following formula is satisfied:

and P is greater than or equal to P _set ≥1

wherein ,a sixth preset threshold; m is the preset minimum signal intensity, rsrp _{n average} The average signal intensity of the first type terminal in a preset time period is obtained; rsrp _Thrl A third preset threshold value; rsrp _Thrh A fourth preset threshold value. In a possible implementation manner, in a scenario where the target signal overlaps the cell, when the transmitting port number determining device determines the number of configurable ports of the joint transmitting port number non-joint transmitting based on the product of the third preset threshold and the transmitting proportion, the configurable port number is taken upwards.

Exemplary, when Rsrp _{n average} At-100 dBm, the transmitting port number determining device determines that the product of the third preset threshold and the transmitting proportion is 24, when Rsrp _{n average} When the transmission port number is-116 dBm, the product of the third preset threshold value and the transmission proportion is determined to be 11.2, and the combined transmission port number is up to the configurable port number 12.

The technical scheme provided by the embodiment at least has the following beneficial effects: the transmitting port number determining device determines the transmitting proportion of the joint transmitting port number based on the average signal intensity of the first type terminal in the preset time period, and determines the joint transmitting port number based on the transmitting proportion, the preset proportion and the maximum configurable port number of the joint transmitting. The higher the average signal intensity of the first type terminal in the preset time period is, the stronger the signal intensity of the target signal overlapping cell is, at the moment, the transmitting proportion is increased, the signals are transmitted with more ports, the average signal intensity of the first type terminal in the preset time period is weaker, at the moment, the transmitting proportion is reduced, the signals are transmitted with fewer ports, and the number of the combined transmitting ports for improving the signal quality is determined.

In a possible implementation manner, as shown in fig. 9 in connection with fig. 5, after determining the number of transmitting ports corresponding to each first type of terminal based on the signal strength of the first type of terminal accessing the target signal overlapping cell, the transmitting port number determining device further needs to determine a signal transmitting mode, and this method can be implemented in the following S901-S904, which will be described in detail below.

S901, the transmission port number determining means determines a first spectral efficiency, a second spectral efficiency, and a third spectral efficiency.

The first spectrum efficiency is the spectrum efficiency of the signal received by the target terminal when the target signal overlapping cell transmits the measurement signal alone.

And the second spectrum efficiency is the spectrum efficiency of the signal received by the target terminal when the target neighbor cell singly transmits the measurement signal.

The third spectrum efficiency is the spectrum efficiency of the signal received by the target terminal when the target signal overlapping cell and the target adjacent cell jointly transmit the measurement signal based on the number of the joint transmission ports; the target terminal is any one of the terminals of the first type.

And S902, the transmitting port number determining device determines that the target signal overlapped cell transmits data to the target terminal independently under the condition that the first frequency spectrum efficiency is larger than the second frequency spectrum efficiency and is larger than the third frequency spectrum efficiency.

In one possible implementation, the target signal overlapping cell transmits a channel sounding reference signal (Sounding Reference Signal, SRS) to terminals within the coverage area of the cell, and the spectral efficiency of reception by the target terminal is determined when the target signal overlapping cell transmits the measurement signal alone.

In yet another possible implementation manner, the target signal overlapping cell may determine, by transmitting a channel state information reference signal (Channel State Information Reference Signal, CSI-RS), a spectral efficiency of reception by the target terminal when the target signal overlapping cell and the target neighbor jointly transmit the measurement signal based on the number of joint transmission ports.

In one possible implementation, the joint transmission may improve the signal coverage, i.e. the signal strength, but the processing complexity and the power increase may improve the interference to other cells, and it may be determined whether to perform the joint transmission by setting a spectrum efficiency ratio threshold, where the larger the value set by the spectrum efficiency ratio threshold is, the smaller the possibility of adopting the joint transmission is under the condition of considering the signal interference to other cells.

In this case, S902 may be specifically implemented as: and when the product of the first spectral efficiency and the spectral efficiency ratio threshold is larger than the product of the second spectral efficiency and the spectral efficiency ratio threshold and is larger than the third spectral efficiency, determining that the target signal overlapping cell independently transmits data to the target terminal.

For example, the spectral efficiency ratio threshold may be set to 1.2, where it is determined that data is transmitted by the target signal overlapping cell alone to the target terminal when the product of the first spectral efficiency and 1.2 is greater than the product of the second spectral efficiency and 1.2 and greater than the third spectral efficiency.

S903, the transmitting port number determining device determines that the target neighbor cell transmits data to the target terminal independently under the condition that the second spectrum efficiency is larger than the first spectrum efficiency and is larger than the third spectrum efficiency.

In one possible implementation, when the product of the second spectral efficiency and the spectral efficiency ratio threshold is greater than the product of the first spectral efficiency and the spectral efficiency ratio threshold, and greater than the third spectral efficiency, it is determined that data is transmitted by the target neighbor cell alone to the target terminal.

S904, the transmitting port number determining device determines that the target signal overlaps the cell and the target neighbor cell under the condition that the third frequency spectrum efficiency is larger than the first frequency spectrum efficiency and larger than the second frequency spectrum efficiency, and transmits data based on the combined transmitting port number.

In one possible implementation, when the third spectral efficiency is greater than the product of the first spectral efficiency and the threshold of the ratio of spectral efficiency and the product of the second spectral efficiency and the threshold of the ratio of spectral efficiency, determining that the target signal overlaps the target neighbor cell, and jointly transmitting data based on the number of joint transmission ports.

The technical scheme provided by the embodiment at least has the following beneficial effects: the transmitting port number determining device predicts the first frequency spectrum efficiency received by the target terminal when the target signal overlapping cell transmits the measurement signal alone; when the target neighbor cell singly transmits a measurement signal, the target terminal receives second spectrum efficiency; when the target signal overlapping cell and the target adjacent cell jointly transmit the measurement signal based on the number of the joint transmission ports, the target terminal receives the third frequency spectrum efficiency, and the optimal signal transmission mode with highest frequency spectrum efficiency is determined.

The processing unit is further configured to determine that, among the at least one preset terminal, a terminal with measured neighbor cell signal strength greater than a signal strength of a serving cell is the first type terminal;

the processing unit is further configured to determine that, in the first type of terminal, a terminal whose average value of the measured signal strength of the serving cell and the signal strength of the target neighbor cell is smaller than the third preset threshold is the second type of terminal;

the processing unit is further configured to determine that, in the first type of terminal, a terminal whose average value of the measured signal strength of the serving cell and the signal strength of the target neighbor cell is greater than the fourth preset threshold is the third type of terminal;

the processing unit is further configured to determine that the target cell is the target signal overlapping cell when a duty cycle of a second type terminal in the first type terminals is smaller than the first preset threshold and a duty cycle of a third type terminal in the first type terminals is smaller than the second preset threshold.
