[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] See Figure 1 , Figure 1 This is a flowchart illustrating an antenna selection method provided in an embodiment of this application. Figure 1 As shown, the antenna selection method may include the following steps:

[0045] Step 101: Obtain the K performance parameter values ​​corresponding to the N data ports under the K level signal combinations. Each of the N data ports supports outputting i level signals, where i is an integer greater than 1, and K is equal to i raised to the power of N.

[0046] It should be noted that the antenna selection method provided in this application is applied to a communication module. This communication module includes a processor, M antennas, N antenna switches, and N data ports and N radio frequency (RF) ports corresponding to the N antenna switches. The processor is connected to the N antenna switches through the N data ports. The N data ports output different level signals to control the conduction state of the N antenna switches, thereby selecting different antennas to connect to the N RF ports. The N RF ports are used to transmit and receive RF signals. N is an integer greater than or equal to 1, and M is a multiple of N. For example, assuming the antenna switch is a single-pole double-throw (SPDT) switch, the data port can output two levels of signals. By setting four SPDT switches, four antennas can be expanded to eight antennas. This allows for the selection of four antennas from the eight antennas to connect to the RF ports, expanding the antenna selection range of the communication module and enabling the communication module to maintain optimal performance using the four selected antennas. The structure of this communication module is as follows: Figure 2 As shown. Specifically, Figure 2 Each antenna switch can be selectively connected to two antennas. When the data port outputs a first-level signal (e.g., a high-level signal), the RF port can be connected to the left antenna via the antenna switch; when the data port outputs a second-level signal (e.g., a low-level signal), the RF port can be connected to the right antenna via the antenna switch. Alternatively, when the data port outputs a first-level signal (e.g., a high-level signal), the RF port can be connected to the right antenna via the antenna switch; when the data port outputs a second-level signal (e.g., a low-level signal), the RF port can be connected to the left antenna via the antenna switch. This embodiment does not impose limitations. Furthermore, the antenna switch in this embodiment can also be a single-pole three-throw switch or a single-pole four-throw switch, etc., and the data port can also support three or four equal-level signal outputs depending on the type of antenna switch. The above examples do not constitute a limitation of this application.

[0047] In this step, the processor can control the level signal of each data port, thereby switching between K combinations of level signals to obtain the corresponding performance parameter value for each combination of level signals. For example, in Figure 2In the communication module shown, since each data port can output either a high-level or low-level signal, the four antenna switches can acquire a total of 16 (2 to the power of 4) combinations of level signals, thus providing 16 performance parameter values. These performance parameters can include parameters such as Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal-to-Interference & Noise Ratio (SINR), and Spectral Efficiency (SE).

[0048] Step 102: Based on the K performance parameter values, determine the optimal level signal combination from the K level signal combinations, where the optimal level signal combination is the level signal combination corresponding to the optimal performance parameter value among the K performance parameter values.

[0049] In this step, after obtaining K performance parameter values, these K values ​​can be sorted to select the optimal performance parameter value. Then, based on the optimal performance parameter value, the optimal level signal combination is obtained. Here, the optimal level signal combination refers to the combination of level signals output by the N data ports of the communication module when the performance parameter values ​​are optimal.

[0050] Step 103: Based on the optimal level signal combination, control N antenna switches to select N target antennas from M antennas and connect them to N radio frequency ports.

[0051] In this step, after determining the optimal combination of level signals, the N data ports can be controlled to output the N level signals corresponding to the optimal combination of level signals, so as to control the N antenna switches to select N target antennas from the M antennas and connect them to the N radio frequency ports.

[0052] In this embodiment, the communication module can automatically obtain the optimal level signal combination corresponding to the optimal performance parameter value under K level signal combinations. Then, it controls N antenna switches through N data ports to select N target antennas corresponding to the optimal level signal combination and connect them to N radio frequency ports. This allows the communication module to automatically maintain its optimal performance state without the need to manually check the performance of each antenna using logs or web pages, or to manually adjust the antenna position and direction to adjust the antenna performance. This improves adjustment efficiency and simplifies manual operation.

[0053] Further, step 102 above, determining the optimal level signal combination from the K level signal combinations based on the K performance parameter values, includes:

[0054] Determine the optimal performance parameter value from K performance parameter values;

[0055] From K combinations of level signals, determine the combination of level signals corresponding to the optimal performance parameter value;

[0056] The combination of level signals corresponding to the optimal performance parameter value is determined as the optimal level signal combination.

[0057] In one embodiment, when determining the optimal level signal combination, the K performance parameter values ​​can be sorted first to select the optimal performance parameter value among the K performance parameter values. Then, based on the optimal performance parameter value, the level signal combination corresponding to the optimal performance parameter value is determined from the K level signal combinations, and this level signal combination corresponding to the optimal performance parameter value is determined as the optimal level signal combination. For example, continuing with... Figure 2 Taking the communication module shown as an example, a total of 16 performance parameter values ​​corresponding to 16 different level signal combinations can be obtained. These 16 performance parameter values ​​can then be sorted in descending order, and the level signal combination corresponding to the largest performance parameter value can be selected as the optimal level signal combination. This ensures that the optimal level signal combination selected by the communication module each time corresponds to the optimal performance parameter value, thus guaranteeing that the communication module signal is in an optimal state and improving the product's competitiveness.

[0058] Furthermore, before determining the optimal level signal combination corresponding to the optimal performance parameter value as the optimal level signal combination in the above steps, the method further includes:

[0059] Determine whether the optimal performance parameter value is greater than a preset threshold;

[0060] If the optimal performance parameter value is determined to be greater than the preset threshold, the following steps are performed: the combination of level signals corresponding to the optimal performance parameter value is determined as the optimal level signal combination.

[0061] In one embodiment, before determining the level signal combination corresponding to the optimal performance parameter value as the optimal level signal combination, it is also necessary to determine whether the optimal performance parameter value is greater than a preset threshold. If the optimal performance parameter value is greater than the preset threshold, the following steps are performed: determining the level signal combination corresponding to the optimal performance parameter value as the optimal level signal combination; if the optimal performance parameter value is less than or equal to the preset threshold, the state of the N antenna switches remains unchanged, that is, the currently connected antennas of the communication module remain unchanged. It should be noted that the preset threshold here can be set according to the actual situation, and this embodiment does not impose a specific limitation.

[0062] In this way, the conditions for antenna switching can be increased. The communication module will only switch the currently connected antenna when the optimal performance parameter value is greater than the preset threshold, thereby avoiding excessive antenna switching, which would affect the normal use of the communication module.

[0063] Furthermore, the optimal performance parameter value is used to characterize the maximum spectral efficiency of the communication module under the combination of K level signals;

[0064] The above steps, including determining whether the optimal performance parameter value is greater than the preset threshold, include:

[0065] Determine whether the maximum spectral efficiency is greater than a preset threshold.

[0066] In one embodiment, spectral efficiency can be selected as a performance parameter. This way, when determining whether the optimal performance parameter value is greater than a preset threshold, it is only necessary to check whether the maximum spectral efficiency is greater than the preset threshold. This approach is more accurate than using parameters such as Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), or Signal-to-Noise Ratio (SINR) as performance parameters in existing technologies. This is because spectral efficiency, also known as system capacity or bandwidth utilization, is defined as the effective information rate R of the system divided by the communication channel bandwidth B, i.e., the number of bits that can be transmitted per second on a unit bandwidth channel. In other words, spectral efficiency comprehensively considers factors such as base station overload and environmental interference, thus providing a more comprehensive consideration than parameters such as Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), or SINR.

[0067] Further, step 103 above, based on the optimal level signal combination, controls N antenna switches to select N target antennas from M antennas to connect with N RF ports, including:

[0068] Based on the optimal combination of level signals, determine the N level signals that need to be output from the N data ports, where each of the N data ports corresponds one-to-one with a level signal in the N level signals.

[0069] Control N data ports to output N level signals to N antenna switches, so that the N antenna switches, under the control of the N level signals, select N target antennas from M antennas and connect the N target antennas to the N RF ports.

[0070] In one embodiment, after determining the optimal combination of signal levels, the required N signal levels for output from the N data ports can be determined based on this optimal combination. Then, the N data ports are controlled to output the N signal levels to the N antenna switches. Under the control of these N signal levels, the N antenna switches select N target antennas from the M antennas and connect these N target antennas to the N RF ports. This allows the communication module to quickly find the optimal signal in weak environments or during rapid movement, ensuring the signal remains in its optimal state and thus improving the product's competitiveness.

[0071] Furthermore, step 101 above, obtaining the K performance parameter values ​​corresponding to the N data ports under K combinations of level signals, includes:

[0072] The level signal of each of the N data ports is switched sequentially, and the performance parameter value corresponding to the current level signal combination is obtained after each switch, until each of the N data ports has been switched.

[0073] In one embodiment, when acquiring K performance parameter values, the level signal of each of the N data ports can be switched sequentially, and the corresponding performance parameter value under the current level signal combination can be acquired after each switch, until each of the N data ports has completed the switch. It should be noted that after switching the level signal combination, the spectral efficiency can be obtained by issuing a QMI-GET command, and the original spectral efficiency under that level signal combination can be updated after obtaining the spectral efficiency. In this way, the performance parameter values ​​of the communication module can be known without manually adjusting the antenna or checking logs, resulting in a better user experience.

[0074] In one embodiment, the antenna selection process provided by this application is as follows: Figure 3 As shown, the specific steps may include the following:

[0075] Step 301: Determine whether the switching of all level signal combinations of the data port is complete.

[0076] If all level signal combinations of the data port have been switched, proceed to step 302; if all level signal combinations of the data port have not been switched, proceed to step 305.

[0077] Step 302: Obtain the maximum spectral efficiency.

[0078] Step 303: Determine whether the maximum spectral efficiency is greater than a preset threshold. This preset threshold can be a pre-set threshold value for switching spectral efficiency.

[0079] If the maximum spectral efficiency is greater than the preset threshold, then proceed to step 304; if the maximum spectral efficiency is less than or equal to the preset threshold, then end the process.

[0080] Step 304: Switch the antenna switch according to the combination of level signals corresponding to the maximum spectral efficiency.

[0081] Step 305: Continue switching the level signal combination of the data port.

[0082] Step 306: Issue the QMI-GET command to obtain the spectrum efficiency.

[0083] Step 307: Update the spectral efficiency of the current level signal combination.

[0084] Through steps 301 to 307 above, the redundant general-purpose input / output ports (GPIOs) in the radio frequency (RF) front-end design can be used to control the diversity antenna switching, facilitating operation and debugging. Furthermore, the SPEFF value for each combination can be obtained through self-adjustment to select a better antenna channel; this parameter is more accurate than previous parameters such as RSRP, RSRQ, and SINR. Additionally, end users do not need to constantly monitor the antenna placement and orientation; instead, the software automatically matches and selects the best antenna channel.

[0085] See Figure 4 This application also provides a communication module, which includes:

[0086] M antennas 410;

[0088] N data ports 430 and N radio frequency ports 440 are provided corresponding to N antenna switches 420.

[0089] The processor 450 is connected to N antenna switches 420 through N data ports 430. The processor 450 is used to acquire K performance parameter values ​​corresponding to K combinations of level signals for the N data ports 430. Each of the N data ports 430 supports outputting i kinds of level signals, where i is an integer greater than 1 and K is equal to the power of i. Based on the K performance parameter values, the processor 450 determines the optimal level signal combination from the K combinations of level signals. The optimal level signal combination is the level signal combination corresponding to the best performance parameter value among the K performance parameter values. Based on the optimal level signal combination, the processor 450 controls the N antenna switches 420 to select N target antennas from M antennas 410 and connect them to the N radio frequency ports 440.

[0090] Furthermore, the processor 450 is also used to determine the optimal performance parameter value from the K performance parameter values; to determine the level signal combination corresponding to the optimal performance parameter value from the K level signal combinations; and to determine the level signal combination corresponding to the optimal performance parameter value as the optimal level signal combination.

[0091] Furthermore, the processor 450 is also used to determine whether the optimal performance parameter value is greater than a preset threshold; if it is determined that the optimal performance parameter value is greater than the preset threshold, the following step is performed: the combination of level signals corresponding to the optimal performance parameter value is determined as the optimal level signal combination.

[0092] Furthermore, the optimal performance parameter value is used to characterize the maximum spectral efficiency of the communication module under the combination of K level signals; the processor 450 is also used to determine whether the maximum spectral efficiency is greater than a preset threshold.

[0093] Furthermore, the processor 450 is also used to determine the N level signals required to be output by the N data ports 430 based on the optimal combination of level signals, wherein the data ports 430 of the N data ports 430 correspond one-to-one with the level signals of the N level signals; and control the N data ports 430 to output the N level signals to the N antenna switches 420, so that the N antenna switches 420 select N target antennas from the M antennas 410 under the control of the N level signals, and connect the N target antennas to the N radio frequency ports 440.

[0094] Furthermore, the processor 450 is also used to sequentially switch the level signal of each of the N data ports 430, and obtain the corresponding performance parameter value under the current level signal combination after each switch, until each of the N data ports 430 has completed the switch.
