[0047] Details

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0049] Referring to Figure 1, Figure 1 is a flow chart of an antenna selection method provided in an embodiment of the present disclosure. As shown in Figure 1, the antenna selection method may include the following steps:

[0050] Step 101: Obtain K performance parameter values ​​corresponding to N data ports under K level signal combinations, wherein each of the N data ports supports outputting i level signals, i is an integer greater than 1, and K is equal to i raised to the Nth power;

[0051] Step 102: Based on the K performance parameter values, determine an optimal level signal combination from the K level signal combinations, wherein the optimal level signal combination is the level signal combination corresponding to the optimal performance parameter value among the K performance parameter values; and

[0052] Step 103: Based on the optimal level signal combination, control N antenna switches to select N target antennas from M antennas to connect to N radio frequency ports.

[0053] It should be noted that the antenna selection method provided in the embodiments of the present disclosure is applied to a communication module, which includes a processor, M antennas, N antenna switches, and N data ports and N RF ports corresponding to the N antenna switches. The processor is connected to the N antenna switches via the N data ports, and the N data ports are used to output different level signals to control the conduction state of the N antenna switches to select different antennas to connect to the N RF ports. The N RF ports are used to transmit and receive RF signals, where N is an integer greater than or equal to 1, and M is a multiple of N. For example, assuming that the antenna switch is a single-pole double-throw switch, the data port can output two level signals. By providing four single-pole double-throw switches, it is possible to expand four antennas to eight antennas, so that four antennas can be selected from the eight antennas to connect to the RF ports, thereby expanding the antenna selection range of the communication module and enabling the communication module to maintain optimal performance using the selected four antennas. The structure of the communication module is shown in Figure 2. Specifically, each antenna switch in Figure 2 can be selectively connected to two antennas. When the data port outputs a first level signal (such as a high level signal), the RF port can be connected to the antenna on the left through the antenna switch; when the data port outputs a second level signal (such as a low level signal), the RF port can be connected to the antenna on the right through the antenna switch. Of course, it is also possible that when the data port outputs a first level signal (such as a high level signal), the RF port can be connected to the antenna on the right through the antenna switch; when the data port outputs a second level signal (such as a low level signal), the RF port can be connected to the antenna on the left through the antenna switch. This is not limited in the embodiments of the present disclosure. Of course, the antenna switch in the embodiments of the present disclosure can also be a single-pole three-throw switch or a single-pole four-throw switch, etc., and the data port can also support the output of three or four equal-level signals depending on the type of the antenna switch. The above examples do not constitute a limitation on the present disclosure.

[0054] In step 101, the processor can control the level signal of each data port to switch between K level signal combinations, thereby obtaining the corresponding performance parameter value under each level signal combination. For example, in the communication module shown in Figure 2, since the level signal output by each data port can be a high level signal or a low level signal, the four antenna switches can obtain a total of 16 (i.e., 2 to the power of 4) level signal combinations, so that 16 performance parameter values ​​can be obtained. Among them, the performance parameter values ​​here can be parameters such as reference signal received power RSRP, reference signal received quality RSRQ, signal to interference & noise ratio (SINR), and spectrum efficiency (SE).

[0055] In step 102, after obtaining the K performance parameter values, the K performance parameter values ​​can be sorted to select the optimal performance parameter value among the K performance parameter values, and then based on the optimal performance parameter value, an optimal level signal combination is obtained. The optimal level signal combination here refers to the combination of level signals output by the N data ports of the communication module when the optimal performance parameter value is reached.

[0056] In step 103, after determining the optimal level signal combination, the N data ports can be controlled to output N level signals corresponding to the optimal level signal combination to control the N antenna switches to select N target antennas from M antennas to connect to the N RF ports.

[0057] 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, and then control N antenna switches through N data ports, select N target antennas corresponding to the optimal level signal combination and connect them to N RF ports, so that the communication module can automatically maintain the optimal performance state without the need to use tools such as logs or web pages to manually check the index performance of each antenna, nor to manually adjust the antenna position and direction to adjust the antenna index performance, thereby improving adjustment efficiency and simplifying manual operations.

[0058] In some embodiments, the above step 102 of determining the optimal level signal combination from the K level signal combinations based on the K performance parameter values ​​includes:

[0059] Determine the optimal performance parameter value from the K performance parameter values;

[0060] Determining the level signal combination corresponding to the optimal performance parameter value from the K level signal combinations; and

[0061] The level signal combination corresponding to the optimal performance parameter value is determined as the optimal level signal combination.

[0062] In certain embodiments, when determining the optimal level signal combination, K performance parameter values ​​can be sorted first to select the optimal performance parameter value from the K performance parameter values, and 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 then the level signal combination corresponding to the optimal performance parameter value is determined as the optimal level signal combination. For example, continuing to take the communication module shown in Figure 2 as an example, a total of 16 performance parameter values ​​corresponding to 16 level signal combinations can be obtained. At this time, these 16 performance parameter values ​​can be sorted in order from large to small, and the level signal combination corresponding to the largest performance parameter value is selected as the optimal level signal combination. In this way, it can be ensured that the optimal level signal combination selected by the communication module each time is the level signal combination corresponding to the optimal performance parameter value, so as to ensure that the communication module signal is in the optimal state, thereby improving the competitiveness of the product.

[0063] In certain embodiments, before the above step of determining the level signal combination corresponding to the optimal performance parameter value as the optimal level signal combination, the method further includes:

[0064] determining whether the optimal performance parameter value is greater than a preset threshold; and

[0065] In the case where it is determined that the optimal performance parameter value is greater than the preset threshold, the step of determining the level signal combination corresponding to the optimal performance parameter value as the optimal level signal combination is executed.

[0066] In certain embodiments, before determining the level signal combination corresponding to the optimal performance parameter value as the optimal level signal combination, it is 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 steps of: determining the level signal combination corresponding to the optimal performance parameter value as the optimal level signal combination; and if the optimal performance parameter value is less than or equal to the preset threshold, maintaining the states of the N antenna switches unchanged, that is, maintaining the antenna currently connected to the communication module unchanged. It should be noted that the preset threshold here can be set according to actual circumstances and is not specifically limited in the present disclosed embodiments.

[0067] In this way, the conditions for antenna switching can be increased. Only when the optimal performance parameter value is greater than the preset threshold will the communication module switch the currently connected antenna, thereby avoiding too frequent antenna switching, which in turn affects the normal use of the communication module.

[0068] In certain embodiments, the optimal performance parameter value is used to characterize the maximum spectrum efficiency of the communication module under a combination of K level signals;

[0069] The above step of determining whether the optimal performance parameter value is greater than a preset threshold includes:

[0070] Determine whether the maximum spectrum efficiency is greater than a preset threshold.

[0071] In certain implementation schemes, spectrum efficiency can be selected as a performance parameter. In this way, when determining whether the optimal performance parameter value is greater than a preset threshold, it is only necessary to determine whether the maximum spectrum efficiency is greater than the preset threshold. In this way, it is more accurate than the prior art of selecting parameters such as reference signal received power RSRP, reference signal received quality RSRQ or signal-to-irritability ratio SINR as performance parameters. This is because spectrum efficiency is also called system capacity and frequency band utilization. It is defined as the effective information rate R of system transmission divided by the communication channel bandwidth B, that is, the number of bits that can be transmitted per second on a unit bandwidth transmission channel. In other words, spectrum efficiency comprehensively considers multiple factors such as base station overload and environmental interference, and is therefore more comprehensive than parameters such as reference signal received power RSRP, reference signal received quality RSRQ or signal-to-irritability ratio SINR.

[0072] In some embodiments, step 103, controlling N antenna switches to select N target antennas from M antennas to connect to N RF ports based on the optimal level signal combination, includes:

[0073] Determining, based on the optimal level signal combination, N level signals required to be output by the N data ports, wherein the data ports in the N data ports correspond one-to-one to the level signals in the N level signals;

[0074] The N data ports are controlled to output N level signals to the N antenna switches, so that the N antenna switches select N target antennas from the M antennas under the control of the N level signals and connect the N target antennas to the N RF ports.

[0075] In certain embodiments, after determining the optimal level signal combination, the N level signals required to be output by N data ports can be determined based on the optimal level signal combination. These N data ports are then controlled to output the N level signals to N antenna switches. Under the control of the N level signals, the N antenna switches select N target antennas from M antennas and connect the N target antennas to the N RF ports. This allows the communication module to quickly find the optimal signal when operating in a weak environment or during rapid movement, ensuring optimal signal conditions and improving product competitiveness.

[0076] In some embodiments, the above step 101 of obtaining K performance parameter values ​​corresponding to N data ports under K level signal combinations includes:

[0077] The level signal of each of the N data ports is switched in turn, and the performance parameter value corresponding to the current level signal combination is obtained after each switching, until each of the N data ports completes the switching.

[0078] In certain embodiments, when obtaining K performance parameter values, the level signal of each of the N data ports can be switched in sequence, and the corresponding performance parameter value under the current level signal combination can be obtained 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 spectrum efficiency can be obtained by issuing a QMI-GET instruction, and after obtaining the spectrum efficiency, the original spectrum efficiency under the level signal combination is updated. In this way, the performance parameter values ​​of the communication module can be known without manually swinging the antenna or checking the log, thereby obtaining a good user experience.

[0079] In some embodiments, the antenna selection process provided by the embodiment of the present disclosure is shown in FIG3 and may include the following steps:

[0080] Step 301: Determine whether all level signal combinations of the data port are switched;

[0081] If all level signal combinations of the data port are switched, step 302 is executed; if all level signal combinations of the data port are not switched, step 305 is executed;

[0082] Step 302: Obtain maximum spectrum efficiency;

[0083] Step 303: Determine whether the maximum spectrum efficiency is greater than a preset threshold. The preset threshold may be a preset threshold value of the switching spectrum efficiency;

[0084] If the maximum spectrum efficiency is greater than the preset threshold, step 304 is executed; if the maximum spectrum efficiency is less than or equal to the preset threshold, the process ends;

[0085] Step 304: Control the antenna switch to switch according to the level signal combination corresponding to the maximum spectrum efficiency;

[0086] Step 305: Continue switching the level signal combination of the data port;

[0087] Step 306: Issue a QMI-GET command to obtain spectrum efficiency; and

[0088] Step 307: Update the spectrum efficiency of the current level signal combination.

[0089] Through steps 301 to 307 above, the redundant General Purpose Input / Output Port (GPIO) designed in the hardware on the Radio Frequency (RF) front end can be used to control the diversity antenna switch, facilitating operation and debugging. Furthermore, the SPEFF value for each combination can be obtained through self-adjustment to select the optimal antenna channel. This parameter is more accurate than previous parameters such as RSRP, RSRQ, and SINR. Furthermore, end users no longer need to constantly monitor the antenna placement and orientation; instead, the software automatically matches and selects the optimal antenna channel.
