The specific implementation of the mobile terminal of the present invention is substantially the same as the following embodiments of the antenna multiplexing method, and is not described herein again.
Based on the above structure, various embodiments of the antenna multiplexing method of the present invention are proposed.
The invention provides an antenna multiplexing method.
Referring to fig. 2, fig. 2 is a flowchart illustrating an antenna multiplexing method according to an embodiment of the present invention.
In the present embodiment, an embodiment of an antenna multiplexing method is provided, and it should be noted that, although a logical sequence is shown in the flowchart, in some cases, the steps shown or described may be performed in a sequence different from that here, and the present invention may be applied to an intelligent terminal.
In this embodiment, the antenna multiplexing method includes:
step S10, obtaining a time division multiplexing worksheet of a preset antenna;
the intelligent terminal receives and transmits various signals such as WiFi signals, GPS signals, Bluetooth signals and the like through an internal antenna, and because the frequencies of different signals are different, the bandwidth requirements for the antennas are also different, and in order to enable the intelligent terminal to meet the requirements of receiving and transmitting various signals, the antennas with different bandwidths are required to be arranged in the intelligent terminal or the antennas with wider frequency range are required to be arranged in the intelligent terminal, however, if various antennas with different bandwidths are arranged in the intelligent terminal, the difficulty of arranging the antennas in the intelligent terminal is caused, the two sides of the intelligent terminal close to the top end are positions for setting antenna priority, because the position is not easy to be held by the hand of the user, because the position for arranging the antenna is limited, the number of the antennas is more, when the positions between the antennas are arranged to be far away, more space of the mobile phone terminal is occupied, and when the positions between the antennas are arranged to be close, the problem of isolation occurs; if a wider frequency band range is set at the intelligent terminal, an antenna capable of multiplexing various signals can be arranged, and the signal transmission performance of the intelligent terminal can be reduced. Firstly, a plurality of antennas are reasonably arranged on the intelligent terminal, so that the space of the intelligent terminal is not excessively utilized, for example, when the intelligent terminal is a mobile phone terminal, two antennas are reasonably arranged, and the mobile phone terminal is used as the intelligent terminal for expansion and description. Two antennas arranged in the mobile phone terminal are preset antennas. And adjusting the working mode of the mobile phone terminal to be a time division multiplexing mode, and acquiring a working table of each preset antenna under the condition that the mobile phone terminal is in the time division multiplexing mode, namely the time division multiplexing working table. Time division multiplexing is a communication technology that different signals are interleaved in different time periods and transmitted along the same channel, and signals in various time periods are extracted and restored to original signals at a receiving end by using a certain method. The time division multiplexing worksheet of the preset antenna records the signal types of the preset antenna and the time period of multiplexing the preset antenna by each signal. It should be noted that the signal can be multiplexed with the predetermined antenna only if the frequency band range supported by the predetermined antenna satisfies the bandwidth of the transmission signal. The bandwidth of the signal WiFi 2.4G is 2400-2483.5MHz, the bandwidth of the signal WiFi 5G is 5150-5825MHz, the bandwidth of the signal WiFi 6G is 5925-7125MHz, the bandwidth of the signal WiFi 6.5G is 6240-6739.2MHz, the bandwidth of the signal WiFi 8G is 7737.6-8326.8MHz, and if the frequency band range supported by the predetermined antenna is 2400-8236.8MHz, the predetermined antenna can transmit the signal.
In some embodiments, step S10 further includes:
step a, acquiring an antenna code of a preset antenna;
and b, acquiring a time division multiplexing working table corresponding to the antenna codes based on a preset mapping relation.
When a plurality of preset antennas exist in the intelligent terminal, in order to distinguish each preset antenna, each preset antenna is numbered, for example, if two preset antennas exist in the mobile phone terminal, two preset antenna numbers are respectively given, namely a preset antenna 1 and a preset antenna 2. Each preset antenna in the intelligent terminal can work in a time division multiplexing mode, so each preset antenna has a time division multiplexing working table, and the mapping relation between the serial number of each preset antenna and the time division multiplexing working table is established in the embodiment. And when the serial number of the preset antenna is obtained, the time division multiplexing working table of the preset antenna can be obtained according to the mapping relation between the serial number of the preset antenna and the time division multiplexing working table.
In some embodiments, before step S10, the method further includes:
step c, determining the unit cycle length of the transmission signal of the preset antenna according to the preset communication requirement;
step d, dividing the unit cycle length into a first time period and a second time period for multiplexing the preset antenna;
and e, formulating a time division multiplexing working table according to the first time interval and the second time interval.
Since the preset antenna can realize multiplexing of multiple signals, in order to facilitate management of the order of transmitting different signals by the preset antenna by the intelligent terminal, the embodiment provides a method for making a time division multiplexing worksheet of the preset antenna, the preset antenna operates according to an operation mechanism in the time division multiplexing worksheet, and the intelligent terminal can effectively manage the order of transmitting different signals by the preset antenna. The unit cycle length is a time unit, the preset communication requirement can be set by a user, the unit cycle length is determined according to the preset communication requirement, the unit cycle length can be flexibly configured, and the experience of the user is improved. And the intelligent terminal carries out segmentation processing on the unit cycle length to obtain a plurality of time intervals, and each time interval transmits a signal, so that the preset antenna can transmit multiple paths of signals within the unit cycle length. The preset antenna repeatedly transmits signals according to the unit period length, so that the signals can be transmitted orderly. When two preset antennas exist in the mobile phone terminal, taking the preset antenna 1 as an example, the unit cycle length of the signal transmitted by the preset antenna 1 is set as T, if the preset antenna 1 has only two kinds of signals for multiplexing, the unit cycle length T is divided into two time periods, the first time period is T1, the second time period is T2(T1+ T2 is T), and then the time division multiplexing worksheet is formulated according to the first time period and the second time period.
Specifically, step e further includes:
step e1, determining a first bandwidth corresponding to a first signal for multiplexing the predetermined antenna in a first time period, and a second bandwidth corresponding to a second signal for multiplexing the predetermined antenna in a second time period;
step e2, a time division multiplexing worksheet is formulated based on the first bandwidth, the second bandwidth, the first time period and the second time period.
Assuming that two signals supportable by the mobile phone terminal are WiFi5/6G and WiFi 2.4G, respectively, regarding the signal WiFi5/6G as a first signal, regarding the signal WiFi 2.4G as a second signal, where the bandwidth of the signal WiFi5/6G is 5150 + 7125MHz, the bandwidth of the signal WiFi 2.4G is 2400-2438.5MHz, then the first bandwidth is 5150 + 7125MHz, the second bandwidth is 2400-2438.5MHz, and similarly, the first time period is T1, and the second time period is T2, the time division multiplexing duty table of the preset antenna based on the first bandwidth, the second bandwidth, the first time period and the second time period is as follows:
| kind of signal | Time period | Bandwidth of |
| WiFi 5/6G | T1 | 5150-7125MHz |
| WiFi 2.4G | T2 | 2400-2438.5MHz |
The time division multiplexing worksheet reflects that the WiFi5/6G signal and the WiFi 2.4G signal multiplex the preset antenna 1 (or preset antenna 2), the preset antenna 1 transmits the WiFi5/6G signal in the T1 period within the unit cycle length, and the preset antenna 1 transmits the WiFi 2.4G signal in the T2 period within the unit cycle length. The time division multiplexing worksheet of the preset antenna 2 may be the same as that of the preset antenna 1 or different from that of the preset antenna 1, but the types of signals transmitted by the preset antenna 1 and the preset antenna 2 are the same.
Step S20, determining the signal to be multiplexed of the preset antenna according to the time division multiplexing worksheet;
the time division multiplexing worksheet records the bandwidth of the signal transmitted in each time interval, and it can be understood that, when the signal received by the mobile phone terminal is not any signal in the time division multiplexing worksheet of the preset antenna, if the preset antenna supports the bandwidth of the signal, the mobile phone terminal allows the signal to multiplex the preset antenna, and regards the signal as a signal to be multiplexed, it should be noted that the signal to be multiplexed may multiplex the preset antenna, but the multiplexing of the preset antenna cannot be immediately realized (the premise that the signal to be multiplexed multiplexes the preset antenna will be explained below). The mobile phone terminal can obtain the bandwidth of the signal supported by the preset antenna by the time division multiplexing worksheet, and further can judge whether the received signal in the non-time division multiplexing worksheet is the signal to be multiplexed.
In some embodiments, step S30 further includes:
step f, acquiring a third bandwidth of a third signal;
and g, when the third bandwidth is overlapped with the first bandwidth, determining the third signal as a signal to be multiplexed.
And when the mobile phone terminal allowing the two signals to multiplex the preset antenna acquires the signal in the non-time division multiplexing table, namely the third signal, determining the bandwidth of the third signal, namely the third bandwidth. Judging whether the third bandwidth overlaps the first bandwidth, when the third bandwidth overlaps the first bandwidth, indicating that the third signal can multiplex the preset antenna, regarding the third signal as a signal to be multiplexed, when the third bandwidth does not overlap the first bandwidth, continuously judging whether the third bandwidth overlaps the second bandwidth, when the third bandwidth overlaps the second bandwidth, the third signal can also be regarded as the signal to be multiplexed, when the third bandwidth does not overlap the second bandwidth, indicating that the preset antenna does not support the transmission of the third signal, and not regarding the third signal as the signal to be multiplexed. It should be noted that the mobile phone terminal always allows only two signals to multiplex the preset antenna at different time intervals, and even if the mobile phone terminal receives the signal to be multiplexed, the mobile phone terminal must further determine whether to allow the signal to be multiplexed to replace the first signal or the second signal to multiplex the preset antenna.
For example, the first signal in the time division multiplexing worksheet is WiFi5/6G, the first bandwidth is 5150 + 7125MHz, the second signal is WiFi 2.4G, the second bandwidth is 2400-2438.5MHz, the third signal received by the mobile terminal is a UWB signal, the bandwidth of the UWB signal is 6240-8236.8MHz, and the overlapping portion of the third bandwidth and the first bandwidth is 6240 + 7125MHz, which indicates that the preset antenna supports the UWB signal, and the UWB signal is regarded as the signal to be multiplexed.
Step S30, when the level of the signal to be multiplexed satisfies a preset condition, controlling the preset antenna to transmit the signal to be multiplexed.
After the signal to be multiplexed is determined, the condition that the mobile phone terminal allows the signal to be multiplexed to multiplex the preset antenna also needs that the level of the signal to be multiplexed meets the preset condition, and when the level of the signal to be multiplexed meets the preset condition, the mobile phone terminal allows the signal to be multiplexed to multiplex the preset antenna. The step of determining whether the signal to be multiplexed satisfies the preset condition specifically includes: and when the level of the signal to be multiplexed is greater than the level of the first signal, determining that the level of the signal to be multiplexed meets a preset condition.
When the bandwidth of the signal to be multiplexed is overlapped with that of the first signal, comparing the level of the signal to be multiplexed with that of the first signal, and when the level of the signal to be multiplexed is greater than that of the first signal, determining that the level of the signal to be multiplexed meets a preset condition; when the bandwidth of the signal to be multiplexed is overlapped with that of the second signal, the level of the signal to be multiplexed is compared with that of the second signal, and when the level of the signal to be multiplexed is greater than that of the first signal, it can also be determined that the level of the signal to be multiplexed satisfies a preset condition. For example, the first signal WiFi5/6G overlaps with the bandwidth of the signal to be multiplexed UWB signal, the level of the WiFi5/6G signal is compared with the level of the UWB signal, the level of the UWB signal is greater than the level of the WiFi5/6G signal, and the level of the UWB signal satisfies the preset condition. It should be noted that, the mobile phone terminal sets the level for each signal, and the general transmission time is shorter and the level setting is higher. The transmission duration of the UWB signal is shorter than that of the WiFi5/6G signal.
Only when the level of the signal to be multiplexed meets the preset condition, the mobile phone terminal allows the signal to be multiplexed to multiplex the preset antenna, and it should be noted that the signal to be multiplexed replaces the signal multiplexing preset antenna having the overlapping bandwidth with itself. When the bandwidth of the signal to be multiplexed is overlapped with that of the first signal, the signal to be multiplexed replaces the first signal to multiplex a preset antenna, and the multiplexing of a second signal is not influenced; when the bandwidth of the signal to be multiplexed is overlapped with that of the second signal, the signal to be multiplexed replaces the second signal to multiplex the preset antenna, and the multiplexing of the first signal is not influenced.
In some embodiments, step S30 further includes:
and h, when the level of the signal to be multiplexed meets a preset condition, controlling the connection switch of the preset antenna and the first module where the first signal is located to be disconnected, and controlling the connection switch of the preset antenna and the module to be multiplexed where the signal to be multiplexed is located to be closed, so as to realize that the signal to be multiplexed multiplexes the preset antenna.
The method for realizing the multiplexing of the signal to be multiplexed and the preset antenna by the mobile phone terminal comprises the following steps: when the mobile phone terminal determines that the bandwidth of the signal to be multiplexed is overlapped with the bandwidth of the first signal and the level of the signal to be multiplexed meets a preset condition, the connection switch of the preset antenna and the module where the first signal is located (namely, the first module) is controlled to be disconnected, and the connection switch of the preset antenna and the module where the signal to be multiplexed is located (namely, the module to be multiplexed) is closed, so that the preset antenna for multiplexing the signal to be multiplexed is realized. It should be noted that the preset antenna 1 and the preset antenna 2 exist in the mobile phone terminal, both the preset antenna 1 and the preset antenna 2 can transmit a first signal, when the preset antenna 1 or 2 transmits the first signal, the preset antenna 1 and the preset antenna 2 are both connected to a first module where the first signal is located, when the preset antenna 1 receives the signal to be multiplexed, a connection switch between the preset antenna 1 and the first module is disconnected, and the connection switch between the preset antenna 1 and the module to be multiplexed where the signal to be multiplexed is located is closed, so that the preset antenna 1 transmits the signal to be multiplexed, and when the preset antenna 1 transmits the signal to be multiplexed, the preset antenna 2 and the connection switch between the first module can be in a closed state to continue transmitting the first signal, so that the mobile phone terminal does not terminate receiving and transmitting the first signal because the signal to be multiplexed replaces the first signal to multiplex the preset antenna 1. The first signal may also be selected to multiplex the predetermined antenna 2, in a similar process as described above.
Referring to fig. 3, fig. 3 is a schematic diagram illustrating connection between an antenna and a signal module in a mobile phone terminal, in which the mobile phone terminal is provided with a preset antenna 1 and a preset antenna 2, the preset antenna 1 and the preset antenna 2 can both transmit and receive a WiFi 2.4G signal and a WiFi5/6G signal, a WiFi 2.4G signal and a WiFi5/6G signal through a WiFi module, a UWB positioning signal is transmitted and received through a UWB module, when the bandwidth of the UWB positioning signal coincides with the bandwidth of the WiFi5/6G signal, and when the level of the UWB positioning signal meets the preset condition, the mobile phone terminal disconnects the connection switch between the preset antenna 1 (or 2) and the WiFi module, closes the connection switch between the preset antenna 1 (or 2) and the UWB module, so that the UWB positioning signal is multiplexed to the preset antenna 1 (or 2) instead of the WiFi5/6G signal to realize that the preset antenna 1 transmits the UWB positioning signal. Only two preset antennas are arranged in the mobile phone terminal, and in the time division multiplexing mode, when one preset antenna is multiplexed by a third signal, the transmission of the other preset antenna to the original two signals is still not influenced. As shown in fig. 3, when the preset antenna transmits a UWB positioning signal, the preset antenna 1 and the preset antenna 2 are required to be matched for transmission, and when the preset antenna receives a UWB signal, only the preset antenna 2 needs to be multiplexed.
It should be noted that, the UWB signal is higher than the WiFi5/6G signal, so the transmission duration of the UWB signal is shorter, and after the transmission of the UWB signal is finished, the mobile phone terminal opens the connection switch between the preset antenna and the UWB module, and closes the connection switch between the preset antenna and the WiFi module, so that the WiFi5/6G reuses the preset antenna.
In this embodiment, the time division multiplexing worksheet of the preset antenna is obtained, the signal to be multiplexed of the preset antenna is determined according to the time division multiplexing worksheet, specifically, the type, time period and bandwidth of the signal to be multiplexed of the preset antenna are obtained from the time division multiplexing worksheet, the signal to be multiplexed of the preset antenna is determined according to the bandwidth, and when the level of the signal to be multiplexed meets the preset condition, the signal to be multiplexed is controlled to multiplex the preset antenna, so that the intelligent terminal supports multiple signal operations without increasing the number of antennas. The signals replaced by the signals to be multiplexed can still be transmitted through other non-preset antennas, and the experience of the user is not influenced.
