Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a method, apparatus and storage medium for determining the number of transmission ports. Background Technology

[0002] Currently, lens antenna technology is being applied to communication service scenarios such as urban expansion and deep coverage of communication systems due to its advantages such as high electromagnetic wave conversion efficiency, less overlap between sub-beams, strong anti-interference ability, ease of implementation of multi-beams, and ability to significantly improve spectrum utilization. Deploying multi-beam lens antennas can expand the signal coverage area of ​​communication network systems and improve spectrum utilization.

[0003] However, because the signal transmitted through the lens antenna is interfered with by strong reflected and refracted waves from the signals transmitted by neighboring cells through the lens antenna during propagation, the signal quality in the overlapping area of ​​the serving cell is poor. How to ensure the signal quality of the serving cell under the condition of signal interference has become an urgent technical problem to be solved. Summary of the Invention

[0043] 1. Luneburg lens antenna

[0044] A lens antenna is an antenna that can convert spherical or cylindrical waves from point or line sources into plane waves, thereby obtaining pencil-shaped, fan-shaped, or other shaped beams. Luneburg lenses are a type of lens, such as... Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a Luneburg lens that emits diverging electromagnetic waves. A Luneburg lens is a perfectly spherical lens. Electromagnetic waves emitted by the feed source are refracted by the Luneburg lens and converted into plane waves for emission. By adjusting the position of the feed source and increasing the number of feed sources, multi-beam, three-dimensional layering can be quickly achieved.

[0045] The diverging beam generated by the electromagnetic wave feed after passing through the Luneburg lens is as follows: Figure 2 As shown, a Luneburg lens can generate multiple diverging electromagnetic wave beams with minimal overlap between sub-beams, strong anti-interference capabilities, and beams that primarily diverge horizontally, exhibiting strong directionality. Traditional base station antennas have an electromagnetic wave conversion efficiency of around 70%, while Luneburg lenses can achieve conversion efficiencies exceeding 90%.

[0046] Luneburg lens antennas feature high gain, wide vertical beamwidth, and multi-beam capability, making them suitable for linear scenarios such as high-speed rail, highways, and large bridges, as well as point-like scenarios in remote rural areas and ultra-long-range coverage scenarios near the sea, balancing coverage and cost advantages. Due to their high electromagnetic wave conversion efficiency, low sub-beam overlap, strong anti-interference capability, ease of multi-beam implementation, and ability to significantly improve spectrum utilization, they are used in communication system expansion and deep cell coverage scenarios. Deploying multi-beam lens antennas can expand the signal coverage area of ​​communication network systems and improve spectrum utilization.

[0047] However, due to the dense concentration of high-rise residential buildings and office buildings in cities, reflections between these buildings can compromise the excellent directivity and low sidelobe interference characteristics of lens antennas in open environments. Furthermore, because cells are relatively close together, strong reflected and refracted waves from neighboring cells can cause significant signal interference in overlapping areas, thus affecting the performance of the lens antenna cell. To ensure a good user communication experience, the serving cell needs to jointly transmit network data with neighboring cells. Therefore, ensuring the signal quality of the serving cell under conditions of signal interference is a pressing technical challenge.

[0048] To address the aforementioned technical problems, this disclosure provides a method, apparatus, and storage medium for determining the number of transmission ports, used to solve the technical problem of ensuring the signal quality of a serving cell under signal interference. The method includes: determining target signal-overlapping cells within a preset area; wherein, the target signal-overlapping cell is a cell where the proportion of second-type terminals among the first-type terminals accessing the cell is less than a first preset threshold, and the proportion of third-type terminals among the first-type terminals is less than a second preset threshold; the signal strength of neighboring cells measured by the first-type terminals is greater than the signal strength of the serving cell, the signal strength measured by the second-type terminals is less than a third preset threshold, and the signal strength measured by the third-type terminals is greater than a fourth preset threshold; determining the number of transmission ports corresponding to each first-type terminal based on the signal strength of the first-type terminals accessing the target signal-overlapping cell; wherein, the target neighboring cell is a neighboring cell among the neighboring cells of the target signal-overlapping cell with the same network configuration as the target signal-overlapping cell; the number of transmission ports is the number of ports jointly transmitted from the target signal-overlapping cell and the target neighboring cell to the first-type terminals, and the number of transmission ports is proportional to the average signal strength.

[0049] In one possible implementation, the above-described method for determining the number of transmission ports can be applied to the transmission port number determination system 300. The following, in conjunction with... Figure 3 This application provides a detailed description of a system 300 for determining the number of transmit ports, as described in an embodiment. Figure 3 As shown, Figure 3 A transmit port number determination system 300 is provided for embodiments of this disclosure. The system includes: a base station 301 of a lens antenna cell and a transmit port number determination device 302.

[0050] In this context, the base station 301 of the lens antenna cell refers to the base station of multiple lens antenna cells within a preset area, including a target signal overlapping cell 301a and a target neighbor cell 301b. The transmit port number determining device 302 is used to determine the target signal overlapping cell 301a and the target neighbor cell 301b within the lens antenna cells. The target signal overlapping cell 301a is a cell where the proportion of second-type terminals among the first-type terminals accessing the cell is less than a first preset threshold, and the proportion of third-type terminals among the first-type terminals is less than a second preset threshold. The signal strength measured by the second-type terminals is less than a third preset threshold, and the signal strength measured by the third-type terminals is greater than a fourth preset threshold. The target neighbor cell 301b is a neighbor cell of the target signal overlapping cell 301a with the same network configuration as the target signal overlapping cell 301a. After determining the target signal overlapping cell 301a and the target neighbor cell 301b within the lens antenna cells, the transmit port number corresponding to each first-type terminal in the target signal overlapping cell 301a is determined based on the signal strength of the first-type terminals accessing the target signal overlapping cell 301a.

[0051] In one possible implementation, the hardware structure of the transmitter port number determination device 302 in the aforementioned transmitter port number determination system 300 includes: Figure 4 The components included in the transmit port number determining device 400 shown below are as follows: Figure 4 Taking the transmit port number determination device 400 shown as an example, the hardware structure of the transmit port number determination device 302 is introduced. For example... Figure 4 As shown, the transmitter port number determination device 400 includes at least one processor 401, a communication line 402, and at least one communication interface 404, and may also include a memory 403. The processor 401, memory 403, and communication interface 404 are connected via the communication line 402.

[0052] The processor 401 may be a central processing unit (CPU), an application-specific integrated circuit (ASIC), or one or more integrated circuits configured to implement the embodiments of this disclosure, such as one or more digital signal processors (DSPs), or one or more field-programmable gate arrays (FPGAs).

[0053] Communication line 402 may include a path for transmitting information between the aforementioned components.

[0054] Communication interface 404 is used to communicate with other devices or communication networks. It can use any transceiver-like device, such as Ethernet, radio access network (RAN), wireless local area network (WLAN), etc.

[0055] The memory 403 may be a read-only memory (ROM) or other type of static storage device capable of storing static information and instructions, random access memory (RAM) or other type of dynamic storage device capable of storing information and instructions, or electrically erasable programmable read-only memory (EEPROM), compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed optical discs, laser discs, optical discs, digital universal optical discs, Blu-ray discs, etc.), magnetic disk storage media or other magnetic storage devices, or any other medium capable of including or storing desired program code in the form of instructions or data structures and accessible by a computer, but not limited thereto.

[0056] In one possible design, the memory 403 can exist independently of the processor 401, meaning the memory 403 can be an external memory of the processor 401. In this case, the memory 403 can be connected to the processor 401 via a communication line 402 to store execution instructions or application code, and its execution is controlled by the processor 401 to implement the method for determining the number of transmit ports provided in the following embodiments of this disclosure. In another possible design, the memory 403 can also be integrated with the processor 401, meaning the memory 403 can be an internal memory of the processor 401. For example, the memory 403 can be a cache, which can be used to temporarily store some data and instruction information.

[0057] As one possible implementation, processor 401 may include one or more CPUs, for example Figure 4 CPU0 and CPU1 in the example. Alternatively, the transmit port number determining device 400 may include multiple processors, such as... Figure 4 The processors 401 and 407 are included. Alternatively, the transmit port number determining device 400 may also include an output device 405 and an input device 406.

[0058] The following provides a detailed description of the method for determining the number of transmission ports provided in the embodiments of this disclosure.

[0059] like Figure 5 As shown, Figure 5 The method for determining the number of transmit ports provided in this disclosure can be applied to, for example... Figure 4 The method in the device for determining the number of transmission ports shown includes the following steps S501-S502, which will be described in detail below.

[0060] S501, The transmitter port number determination device determines the target signal overlap cell within the preset area.

[0061] Among them, the target signal overlapping cell is a cell in which the proportion of the second type of terminals accessing the target signal overlapping cell among the first type of terminals accessing the target signal overlapping cell is less than a first preset threshold, and the proportion of the third type of terminals accessing the target signal overlapping cell among the first type of terminals accessing the target signal overlapping cell is less than a second preset threshold; the signal strength of the neighboring cell measured by the first type of terminal is greater than the signal strength of the serving cell, the signal strength of the serving cell measured by the second type of terminal is less than a third preset threshold, and the signal strength of the serving cell measured by the third type of terminal is greater than a fourth preset threshold.

[0062] In one possible implementation, the transmit port determination device instructs the base station of a cell within a preset area to send a Synchronization Signal Block (SSB) signal so that the terminal within the preset area can perform signal strength measurement. The transmit port determination device then determines a first type of terminal, a second type of terminal, and a third type of terminal based on the signal strength measurement report.

[0063] For example, the first preset threshold is 60%, and the second preset threshold is 70%. When the proportion of the second type of terminal among the first type of terminals in a cell within the preset area is less than 60%, and the proportion of the third type of terminal among the first type of terminals is less than 70%, the transmit port number determining device determines that the cell is the target signal overlapping cell.

[0064] It is understandable that in the target signal overlapping cell, the proportion of the second type of terminals whose signal strength is less than the third preset threshold among the first type of terminals accessed is less than the first preset threshold, and the proportion of the third type of terminals whose signal strength is greater than the fourth preset threshold among the first type of terminals accessed is less than the second preset threshold. That is, the target signal overlapping cell is a target signal overlapping cell in which the proportion of coverage overlapping areas with strong signal strength is similar to that of coverage overlapping areas with weak signal strength.

[0065] S502, The transmitter port number determination device determines the number of transmitter 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.

[0066] Among them, the target neighbor cell is the neighbor cell of the target signal overlapping cell with the same network configuration as the target signal overlapping cell; the number of transmission ports is the number of ports jointly transmitted from the target signal overlapping cell and the target neighbor cell to the first type of terminal, and the number of transmission ports is proportional to the average signal strength.

[0067] It is understandable that when the network configuration of a neighboring cell is the same as that of the cell whose target signal overlaps with it, the neighboring cell can act as a cooperating cell for joint transmission.

[0068] Understandably, the higher the proportion of Type II terminals among the Type I terminals accessing the target signal overlapping cell, the higher the signal strength of the target signal overlapping cell. When the signal quality of the target signal overlapping cell is strong, the number of ports for joint transmission is determined based on the proportion of the overlapping area with strong signal strength. Increasing the number of ports for joint transmission improves signal coverage and data transmission capacity, thereby ensuring the signal quality of the transmitted signals.

[0069] The technical solution provided by the above embodiments can bring at least the following beneficial effects: The transmission port number determination device in this disclosure first determines the target signal overlapping cell within a preset area; wherein the target signal overlapping cell is a cell in which the proportion of the second type terminal among the first type of access terminals is less than a first preset threshold and the proportion of the third type terminal among the first type of terminals is less than a second preset threshold; the signal strength of the neighboring cell measured by the first type of terminal is greater than the signal strength of the serving cell, the signal strength measured by the second type of terminal is less than a third preset threshold, and the signal strength measured by the third type of terminal is greater than a fourth preset threshold; that is, the target signal overlapping cell within the preset area that generates coverage overlapping area, and the proportion of coverage overlapping area with strong signal strength and coverage overlapping area with weak signal strength is similar. Then, based on the signal strength of the first type of terminal accessing the target signal overlapping cell, the number of transmission ports corresponding to each first type of terminal is determined, wherein the target neighboring cell is a neighboring cell in the target signal overlapping cell with the same network configuration as the target signal overlapping cell; the number of transmission ports is the number of ports jointly transmitted from the target signal overlapping cell and the target neighboring cell to the first type of terminal, and the number of transmission ports is proportional to the average signal strength. In other words, when the proportions of overlapping coverage areas with strong signal strength and those with weak signal strength are similar, the number of ports for joint transmission is determined based on the signal strength of each Type 1 terminal. Type 1 terminals with stronger signal strength increase the number of ports for joint transmission, transmitting with more ports to improve signal coverage and data transmission capacity, thereby ensuring the signal strength of the transmitted signal. Type 1 terminals with weaker signal strength decrease the number of ports for joint transmission, transmitting with fewer ports, allocating channel resources to fewer ports, thus ensuring the signal strength of the transmitted signal. In other words, the signal quality of joint transmission is guaranteed even in the event of signal interference.

[0070] In one possible implementation, combining Figure 5 ,like Figure 6 As shown, the process of determining the target signal overlapping cell within the preset area by the above-mentioned S501 and the transmitter port number determination device can be specifically implemented by the following S601-S606, which will be described in detail below.

[0071] S601, The transmitter port number determination device receives a measurement report from at least one preset terminal.

[0072] The preset terminal is the terminal that accesses the target cell; the target cell is any cell within the preset area.

[0073] In one possible implementation, the transmit port number determination device instructs the target cell to send an SSB signal. Upon receiving the SSB signal, the terminal performs signal measurements based on the SSB signal, generates a measurement report based on the measurement results, and sends the SSB signal measurement report to the target cell. The transmit port number determination device obtains the measurement report sent by the terminal from the target cell and determines the measurement report for event A3 that satisfies the following formula 1.

[0074] S602, the transmitter port number determination device determines the serving cell signal strength, neighboring cell signal strength, and target neighboring cell signal strength measured by each preset terminal based on the measurement report of at least one preset terminal.

[0075] It is understandable that the serving cell is the target cell for the preset terminal to access.

[0076] In one possible implementation, after receiving a measurement report within a preset time period, the transmitter port number determination device acquires the measurement results, frequency offset, and specific offset of the serving cell in the measurement report; as well as the measurement results, frequency offset, and specific offset of each neighboring cell; the measurement results include signal strength.

[0077] S603, The transmitter port number determination device determines that among at least one preset terminal, the terminal whose measured neighbor cell signal strength is greater than the signal strength of the serving cell is a first type of terminal.

[0078] In one possible implementation, when the signal strength of the serving cell and the signal strength of the neighboring cell satisfy the following formula 1 within a preset time period, the measured signal strength of the neighboring cell is greater than the signal strength of the serving cell.

[0079] Mn + Ofn + Ocn – Hys > Ms + Ofs + Ocs + Off Formula 1

[0080] Where Ms represents the measurement result of the serving cell; Mn represents the measurement result of the neighboring cell; Ofs represents the frequency offset of the serving cell and Ofn represents the frequency offset of the neighboring cell; Ocs represents the specific offset of the serving cell and Ocn represents the specific offset of the neighboring cell; Hys represents the amplitude hysteresis of the measurement result; and Off represents the offset of the measurement result.

[0081] For example, the transmitter port number determination device determines that the terminal that satisfies Mn+Ofn+Ocn–Hys>Ms+Ofs+Ocs+Off and the duration of this relationship is greater than a preset duration is a first type of terminal, and determines the number of first type terminals.

[0082] S604. The transmitter port number determination device determines that among the first type of terminals, the terminal whose average signal strength of the serving cell and the target neighbor cell is less than a third preset threshold is a second type of terminal.

[0083] In one possible implementation, within a preset time period, the transmit port number determining device determines, based on the measurement reports of each preset terminal within the preset time period, the number of second-type terminals in the first-type terminals whose average signal strength of the serving cell and the target neighboring cell is less than a third preset threshold.

[0084] For example, the third preset threshold is -110dBm, and the transmit port number determination device determines the number of second type terminals in each first type terminal whose average signal strength of the receiving serving cell and the target neighboring cell is less than -110dBm through the signal strength measurement report.

[0085] S605, The transmitter port number determination device determines that among the first type of terminals, the terminal whose average signal strength of the serving cell and the target neighbor cell is greater than the fourth preset threshold is a third type of terminal.

[0086] In one possible implementation, within a preset time period, the transmit port number determining device determines, based on the measurement reports of preset terminals within the preset time period, the number of third-type terminals in each first-type terminal whose average signal strength of the serving cell and the target neighboring cell is greater than a fourth preset threshold.

[0087] S606. If the proportion of second-type terminals in the first type of terminals is less than a first preset threshold and the proportion of third-type terminals in the first type of terminals is less than a second preset threshold, the transmission port number determining device determines the target cell as the target signal overlapping cell.

[0088] It is understandable that a target signal overlapping cell is a target signal overlapping cell where the proportion of coverage overlapping areas with strong signal strength and coverage overlapping areas with weak signal strength is similar due to signal overlap and interference between target cells. When the proportion of the second type of terminal is less than the first preset threshold and the proportion of the third type of terminal is less than the second preset threshold, it can be determined that the proportion of coverage overlapping areas with strong signal strength and coverage overlapping areas with weak signal strength in the target cell is similar, that is, the target cell is determined to be a target signal overlapping cell.

[0089] For example, the first preset threshold is 60%, the second preset threshold is 70%, and when the proportion of the second type of terminal is less than 60% and the proportion of the third type of terminal is less than 70%, the target cell is determined to be the target signal overlapping cell.

[0090] It is understood that the above embodiment is a method for a transmitter port number determination device to determine a cell in a preset area as a target signal overlapping cell. The transmitter port number determination device can perform the method provided in the above embodiment on all cells in the preset area to determine all target signal overlapping cells in the preset area.

[0091] The technical solution provided by the above embodiments can bring at least the following beneficial effects: The transmit port number determination device receives the measurement report of the preset terminal, and based on the measurement report of the preset terminal, determines the signal strength of the neighboring cell, the signal strength of the serving cell, and the signal strength of the target neighboring cell measured by each preset terminal, and further determines that among the preset terminals, the terminal whose measured neighboring cell signal strength is greater than the signal strength of the serving cell is a first type terminal. That is, it determines the number of first type terminals affected by signal overlap in the target cell within the preset area. The transmit port number determination device determines that among the first type terminals, the terminal whose average measured signal strength of the serving cell and the signal strength of the target neighboring cell is less than a third preset threshold is a second type terminal, and the terminal whose average measured signal strength of the serving cell and the signal strength of the target neighboring cell is greater than a fourth preset threshold is a third type terminal. That is, it determines the number of second type terminals with weaker signal strength after signal overlap and the number of third type terminals with stronger signal strength among the first type terminals affected by signal overlap. When the proportion of the second type of terminal is less than the first preset threshold and the proportion of the third type of terminal is less than the second preset threshold, it is determined that the proportion of the coverage overlap area with strong signal strength and the coverage overlap area with weak signal strength of the target cell is similar, and the target cell is determined to be the target signal overlap cell.

[0092] In one possible implementation, combining Figure 6 ,like Figure 7 As shown in S604, before the transmitting port number determining device determines that the terminal in the first type of terminal whose average signal strength of the serving cell and the target neighboring cell is greater than the second preset threshold is a second type of terminal, it is also necessary to determine the target neighboring cell in the neighboring cells of the serving cell. This process can be implemented through the following S701-S702, which are described in detail below:

[0093] S701, the transmitter port number determination device obtains the network configuration of the serving cell, as well as the network configuration and PRB utilization of each neighboring cell of the serving cell.

[0094] In one possible implementation, the transmitter port number determination device can obtain the identifier of the serving cell and each neighboring cell of the serving cell through a measurement report, and obtain the network configuration and PRB utilization of each neighboring cell of the serving cell from the base station of the serving cell and the neighboring cells based on the identifier of the serving cell and each neighboring cell of the serving cell.

[0095] In one possible implementation, the network configuration information includes, but is not limited to, at least one of the following: frequency band, uplink and downlink frequency points, uplink and downlink bandwidth, subcarrier spacing, time slot ratio, cyclic prefix length, and uplink and downlink shared channel configuration.

[0096] S702, The transmitting port number determination device determines the target neighboring cell among the neighboring cells of the serving cell that has the same network configuration as the serving cell and whose PRB utilization rate is greater than the fifth preset threshold.

[0097] For example, the transmit port number determination device determines the frequency band, uplink and downlink frequency points, uplink and downlink bandwidth, subcarrier spacing, time slot ratio, cyclic prefix length, and uplink and downlink shared channel configuration of the neighboring cells of the serving cell, and determines the target neighboring cells as those that have the same frequency band, uplink and downlink frequency points, uplink and downlink bandwidth, subcarrier spacing, time slot ratio, cyclic prefix length, and uplink and downlink shared channel configuration as the serving cell and have a PRB utilization rate greater than 60%.

[0098] The technical solution provided by the above embodiments can bring at least the following beneficial effects: the transmission port number determination device obtains the network configuration of the serving cell, the network configuration and physical resource block (PRB) utilization rate of each neighboring cell of the serving cell through the measurement report, and determines the target neighboring cell with the same network configuration as the serving cell and a lower PRB utilization rate as the cooperating cell for joint transmission.

[0099] In one possible implementation, combining Figure 7 ,like Figure 8 As shown, the process of determining the number of transmission ports for each first-type terminal based on the signal strength of the first-type terminal in the overlapping cell of the target signal, as described above in S502, can be specifically implemented through the following S801-S803, which will be explained in detail below.

[0100] S801, The transmitter port number determination device determines the product of the maximum number of transmitter ports that can be combined and a preset ratio, which is the sixth preset threshold.

[0101] The maximum number of joint transmission ports is the minimum of the number of configurable ports in the target signal overlapping cell and the number of configurable ports in the target neighboring cell.

[0102] In one possible implementation, the preset ratio is a preset ratio determined based on the target signal overlapping cell scenario.

[0103] In one possible implementation, the joint launch currently supports a maximum of 32 antenna ports, and the number of configurable ports for the joint launch can be 1, 2, 4, 8, 12, 16, 24, or 32.

[0104] For example, the preset ratio is one-half, and the transmit port number determining device determines one-half of the maximum number of transmit ports that can be jointly transmitted in the target signal overlapping cell, which is the sixth preset threshold.

[0105] S802, The device for determining the number of transmission ports determines the transmission ratio of the joint transmission ports based on the average signal strength of the first type of terminal within a preset time period.

[0106] The transmission ratio is proportional to the average signal strength of the first type of terminal within a preset time period.

[0107] It is understandable that the stronger the average signal strength of the first type of terminal within a preset time period, the stronger the signal strength of the target signal overlapping cell. At this time, it is necessary to increase the transmission ratio of the port, transmit the signal with more ports, expand the signal coverage and data transmission volume, thereby improving the signal quality.

[0108] S803, the transmitter port number determination device determines the joint transmitter port number based on the product of the sixth preset threshold and the transmitter ratio.

[0109] In one possible implementation, the number P of antenna ports for joint transmission of signals set Satisfy the following formula:

[0110] And P≥P set ≥1

[0111] in, The sixth preset threshold; M is the preset minimum signal strength, Rsrp n平均 Rsrp represents the average signal strength of the first type of terminal within a preset time period. Thrl The third preset threshold; Rsrp Thrh The fourth preset threshold is used. In one possible implementation, in the scenario of overlapping target signals in cells, when the transmit port number determining device determines the number of configurable ports for joint transmission (excluding joint transmission) based on the product of the third preset threshold and the transmission ratio, the configurable port number is taken upwards.

[0112] For example, when Rsrp n平均 When the value is -100dBm, the transmitter port number determination device determines that the product of the third preset threshold and the transmission ratio is 24, and when Rsrp n平均 When the value is -116dBm, the product of the third preset threshold and the transmission ratio is 11.2, and the number of joint transmission ports is taken up to the configurable number of ports, which is 12.

[0113] The technical solution provided by the above embodiments can bring at least the following beneficial effects: The transmission port number determining device determines the transmission ratio of the joint transmission port number based on the average signal strength of the first type of terminal within a preset time period, and determines the joint transmission port number based on the transmission ratio, the preset ratio, and the maximum configurable number of joint transmission ports. The higher the average signal strength of the first type of terminal within the preset time period, the stronger the signal strength of the target signal overlapping cell; in this case, increasing the transmission ratio allows for signal transmission with more ports. Conversely, if the average signal strength of the first type of terminal within the preset time period is weak, decreasing the transmission ratio allows for signal transmission with fewer ports, thus determining the joint transmission port number that improves signal quality.

[0114] In one possible implementation, combining Figure 5 ,like Figure 9 As shown in S502, after determining the number of transmission ports for each type of terminal based on the signal strength of the first type of terminal in the overlapping cell of the target signal, the device also needs to determine the signal transmission mode. This method can be implemented through the following S901-S904, which will be described in detail below.

[0115] S901, the transmitter port number determining device determines the first spectral efficiency, the second spectral efficiency, and the third spectral efficiency.

[0116] The first spectral efficiency is the spectral efficiency of the signal received by the target terminal when the target signal overlapping cell transmits the measurement signal alone.

[0117] The second spectral efficiency is the spectral efficiency of the signal received by the target terminal when the target neighboring cell transmits the measurement signal alone.

[0118] The third spectral efficiency is the spectral efficiency of the signal received by the target terminal when the target signal overlapping cell and the target neighboring cell jointly transmit measurement signals based on the number of joint transmission ports; the target terminal is any terminal in the first type of terminal.

[0119] S902, the transmitter port number determination device determines that data will be transmitted separately from the target signal overlapping cell to the target terminal when the first spectral efficiency is greater than the second spectral efficiency and the third spectral efficiency.

[0120] In one possible implementation, the target signal overlapping cell sends a channel sounding reference signal (SRS) to terminals within the cell's coverage area to determine the spectral efficiency received by the target terminal when the target signal overlapping cell transmits the measurement signal alone.

[0121] In another possible implementation, the target signal overlapping cell can determine the spectral efficiency received by the target terminal when the target signal overlapping cell and the target neighboring cell jointly transmit measurement signals based on the number of joint transmission ports by transmitting a Channel State Information Reference Signal (CSI-RS).

[0122] In one possible implementation, joint transmission can improve signal coverage and signal strength, but the increased processing complexity and power will increase interference to other cells. Whether to conduct joint transmission can be determined by setting a spectral efficiency ratio threshold. Considering the interference to other cell signals, the larger the spectral efficiency ratio threshold is set, the less likely joint transmission will be adopted.

[0123] In this case, S902 can be specifically implemented as follows: when the product of the first spectral efficiency and the spectral efficiency ratio threshold is greater than the product of the second spectral efficiency and the spectral efficiency ratio threshold, and is greater than the third spectral efficiency, it is determined that data will be transmitted separately from the target signal overlapping cell to the target terminal.

[0124] For example, the spectral efficiency ratio threshold can be set to 1.2. In this case, 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 is also greater than the third spectral efficiency, it is determined that the target signal overlapping cell will transmit data to the target terminal separately.

[0125] S903, the transmitter port number determination device determines that data will be transmitted from the target neighbor cell to the target terminal separately when the second spectral efficiency is greater than the first spectral efficiency and the third spectral efficiency.

[0126] 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 is also greater than the third spectral efficiency, it is determined that the target neighboring cell will transmit data to the target terminal separately.

[0127] S904. When the third spectral efficiency is greater than the first spectral efficiency and greater than the second spectral efficiency, the transmission port number determination device determines that the target signal overlapping cell and the target neighbor cell jointly transmit data based on the joint transmission port number.

[0128] In one possible implementation, when the third spectral efficiency is greater than the product of the first spectral efficiency and the spectral efficiency ratio threshold and the product of the second spectral efficiency and the spectral efficiency ratio threshold, it is determined that the target signal overlapping cell and the target neighbor cell jointly transmit data based on the number of joint transmission ports.

[0129] The technical solution provided by the above embodiments can bring at least the following beneficial effects: the transmission port number determination device determines the optimal signal transmission mode with the highest spectral efficiency by predicting the first spectral efficiency received by the target terminal when the target signal overlapping cell transmits the measurement signal alone; the second spectral efficiency received by the target terminal when the target neighbor cell transmits the measurement signal alone; and the third spectral efficiency received by the target terminal when the target signal overlapping cell and the target neighbor cell jointly transmit the measurement signal based on the joint transmission port number.
