For example, the WiFi system and the 3GPP Long Term Evolution (LTE) system or the 5G New air interface (NR) system have mutual interference such as adjacent frequency, harmonic, common frequency, and intermodulation. Specifically, as shown in fig. 1, the spectrum includes an Industrial, Scientific, Medical (ISM) Band, and this frequency Band (2.4GHz to 2.4835GHz) is mainly open to Industrial, Scientific, Medical, and three major organizations, and the frequency Band is defined by the Federal Communications Commission (FCC) in the united states and belongs to a Free License (Free License) frequency Band, i.e., there is no limitation of so-called usage authorization. Wherein, 2.4GHz is the common ISM frequency band of each country, so that wireless networks such as WiFi wireless local area network, Bluetooth and ZigBee can work on the 2.4GHz frequency band. Adjacent frequency mutual interference can be generated between a 2.4GHz channel in a WiFi network system and B40/n40, B7/n7 and B41/n41 frequency bands in a cellular network, and the receiving performance of the frequency bands of the cellular network can be influenced during WiFi transmission; correspondingly, the transmission of the cellular network also affects the reception performance of the WiFi antenna.

The technical scheme provided by the embodiment of the application can solve the problem of mutual interference generated when the cellular network system and the WiFi network system work in adjacent frequency or same frequency bands under various scenes. Before describing the technical solution in detail, first, the antenna distribution of different network systems in the terminal device is described. As shown in fig. 2, a schematic diagram of a possible antenna distribution is provided. The figure shows a distribution of two antenna systems, wherein the first antenna system comprises at least one first antenna, such as a WiFi antenna 1 and a WiFi antenna 2, said WiFi antenna 1 and WiFi antenna 2 being used for antennas for performing communication traffic under a WiFi network system.

Further, which antenna of the first antenna system and the second antenna system is used by the terminal device to perform communication transmission in different systems may be determined by a smart antenna selection policy, for example, the terminal device may select different antennas according to different states of sliding open or closing of upper and lower screens, unfolding or folding of left and right screens, and the like in a multi-screen mobile phone.
In addition, the terminal equipment described in this embodiment may be mobile terminals such as mobile phones (or so-called "cellular" phones) and computers with mobile terminals, for example, portable, pocket, hand-held, computer-included, or vehicle-mounted mobile devices, which exchange language and/or data with a radio access network. Such as Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like.

The methods provided in the examples of the present application are explained in detail below. Referring to fig. 4, this embodiment provides an antenna selection method, which is applied to a terminal device, where the terminal device includes a first antenna system and a second antenna system, the first antenna system includes at least one first antenna, the second antenna system includes at least one candidate second antenna, further, the first antenna system further includes a first processing module, and the second antenna system further includes a second processing module.
Optionally, the first processing module and the second processing module may be respectively arranged in the terminal device as independent communication chips, or alternatively, the two processing modules are integrated in one Chip, such as a System on Chip (SoC), the method provided in this embodiment is described by taking the second processing module or a Chip where the second processing module is located as an example, and the method is shown in fig. 4 and includes:
step 101: first frequency configuration information and second frequency configuration information are obtained. The first frequency configuration information corresponds to a first antenna system of a first communication system, the second frequency configuration information corresponds to a second antenna system of a second communication system, the first antenna system comprises at least one first antenna, the second antenna system comprises at least one candidate second antenna, and the second communication system is different from the first communication system.
Further, the first frequency configuration information includes a first frequency (frequency) and a first Bandwidth (BW), the second frequency configuration information includes a second frequency and a second bandwidth, and the first frequency and the first bandwidth may be configured by a router or an access point of WiFi, and the second frequency and the second bandwidth may be configured by a cellular communication base station.
Specifically, the acquiring, by the terminal device, the first configuration information includes: a second processing module corresponding to a second antenna system acquires the first frequency configuration information reported by a first processing module corresponding to the first antenna system; further, a first antenna system of the terminal device receives first indication information sent by an access point, a first processing module of the first antenna system analyzes the first indication information to obtain a first frequency and a first bandwidth, and selects a first antenna to execute a communication service of a first system using the first frequency and the first bandwidth, and the first processing module sends the first configuration information to the second processing module through a communication bus, which may be described with reference to fig. 6 specifically.
Similarly, the terminal device acquiring the second configuration information includes: a second processing module of the second antenna system receives second indication information sent by the base station, the second processing module analyzes the second indication information to obtain a second frequency and a second bandwidth, and can further select a second antenna to execute a communication service of a second communication system by using the second frequency and the second bandwidth. The first antenna system is a WiFi system, and the second antenna system is a cellular network system. Further, in the WiFi system, the first frequency and the first bandwidth in the first frequency configuration information may be configured by a network device, such as a router or an access point of WiFi. In the cellular network system, the second frequency and the second bandwidth are configured by a cellular communication base station. Alternatively, the first antenna system may also be a GPS system, or a system integrating the WiFi and GPS functions.
It can be understood that, the first frequency configuration information obtained in step 101 may also be dynamically changed, for example, if the first antenna system detects that the first indication information sent by the router or the access point of the WiFi changes, that is, the first frequency and the first bandwidth configured to the terminal device change, the first frequency and the first bandwidth of the first antenna system are updated accordingly, and the updated first frequency configuration information is notified to the second processing module of the second antenna system, so that the second processing module of the second antenna system obtains the updated first frequency and the updated first bandwidth. Similarly, if the second processing module of the second antenna system needs to send the second configuration information to the first processing module of the first antenna system, the second processing module of the second antenna system may also dynamically update the second frequency and the second bandwidth, and send the second frequency and the second bandwidth to the first processing module of the first antenna system.
Step 102: determining a target antenna among the at least one candidate second antenna according to the first frequency configuration information and the second frequency configuration information, the target antenna being a second antenna adapted to perform simultaneous transmission with the at least one first antenna.
Specifically, step 102 includes: and determining the target antenna according to the first frequency and the first bandwidth, the second frequency and the second bandwidth and a pre-configured frequency relation table. Wherein the frequency relationship table comprises: a plurality of first frequency bands of the first antenna system and at least one first bandwidth corresponding to each of the first frequency bands; a plurality of second frequency bands of the second antenna system and at least one second bandwidth corresponding to each of the second frequency bands; at least one second antenna corresponding to each first frequency band, each first bandwidth, each second frequency band, and each second bandwidth. Wherein the at least one second antenna is included in the at least one candidate second antenna and includes the target antenna.
For example, table 2 shows a frequency relationship table. The table is used to select a target antenna among the at least one candidate second antenna, i.e. to select one second antenna as the target antenna in case the first antenna in the first antenna system is unchanged. Alternatively, in another case, the antennas in the table may be configured as first antennas, and then the first antennas are selected as target antennas for communication under the condition that the second antennas are not changed. The present embodiment is described by taking the former case as an example.
TABLE 2
In table 2, the first antenna system corresponds to two first frequency bands, which are a frequency range 1 and a frequency range 2, respectively, where the frequency range 1 and the frequency range 2 both correspond to 4 bandwidths, which are: 20MHz, 40MHz, 80MHz and 160 MHz. Similarly, the second antenna system comprises a second frequency band, i.e. a second frequency range, wherein a plurality of bandwidths, for example: 5MHz, 10MHz and 15MHz … …. The second antenna system may have a plurality of second frequency bands, each of which may correspond to a table shown in table 2, or the tables corresponding to the plurality of second frequency bands of the second antenna system are combined together to form a table, and table 2 only uses one second frequency band as an example, but is not limited to the invention.
Further, a table lookup operation may be performed in step 102. For example, at least one second antenna corresponding to the first frequency (range) and the first bandwidth, and the second frequency (range) and the second bandwidth are respectively determined in the frequency relation table, and if the second antenna is determined to be "antenna 1 or 2" by looking up the table, one of the two antennas is selected as the target antenna. Before determining the target antenna in step 102, the method may further include: judging whether a first antenna system generates mutual interference with a second antenna system, namely whether a first antenna used in the first antenna system generates interference with a second antenna used in the second antenna system, and further judging whether the first frequency is positioned in one of a plurality of first frequency bands and whether the second frequency is positioned in one of a plurality of second frequency bands; and if the first frequency is located in one of the plurality of first frequency bands and the second frequency is located in one of the plurality of second frequency bands, triggering the operation of determining the target antenna according to the first frequency configuration information and the second frequency configuration information. In this embodiment, if it is determined that the first frequency is in the frequency range 1 or the frequency range 2 and the second frequency is in the second frequency range, it is determined that the currently used first antenna interferes with at least one second antenna; otherwise, no interference is generated.
Step 103: and executing a first communication service of the first communication system by using the at least one first antenna, and executing a second communication service of the second communication system by using the target antenna. The first communication system is cellular communication, and the second communication system is WiFi communication or GPS communication. Or, optionally, the first communication system is WiFi communication or GPS communication, and the second communication system is cellular communication. The first communication service and the second communication service include: at least one of communication data and communication control information and the like is transmitted or received.
According to the method provided by the embodiment, the target antenna suitable for simultaneous transmission of two different antenna systems is selected by acquiring the antenna configuration information, such as frequency and bandwidth information, of the two different antenna systems, the target antenna is one of the candidate second antennas in the second antenna system, and the target antenna is used for executing the communication service of the corresponding communication system, so that interference with the first antenna system is avoided.
It should be noted that, in this embodiment, the frequency relationship table may be set and generated according to the isolation between the first antenna and the second antenna in the terminal device. The isolation is used for representing the interference degree between at least one first antenna and at least one second antenna, wherein the interference degree is smaller for two antennas with higher isolation. For example, in the terminal device antenna distribution diagram shown in fig. 2, the distance between the antenna 3 or the antenna 4 and the WiFi antenna 1 and the WiFi antenna 2 in the first antenna system is short, and the isolation is small; the distance between the antenna 1 or the antenna 2 and the WiFi antenna 1 and the WiFi antenna 2 is far, the isolation degree is large, so the isolation degree of the antenna 1 and the antenna 2 is larger than the isolation degree of the antenna 3 and the antenna 4, so when interference is generated between the antenna 3 or the antenna 4 in the second antenna system and the WiFi antenna 1 and the WiFi antenna 2 in the first antenna system, the antenna 1 or the antenna 2 is preferentially switched and used as a target antenna to increase the isolation degree of the two systems and reduce the interference, and therefore the table can be configured in advance based on the isolation degree conditions of different antennas obtained in production line calibration or test. In addition, product forms of the current two antenna systems are also considered in the pre-configuration of the frequency relationship table, mutual interference characteristics of products are extracted, for example, which second frequency bands in the second antenna systems interfere with the first antenna system, for example, a WiFi network, preset antenna parameters are obtained through a series of experimental combinations, and finally the frequency relationship table is generated.
The method of the above-described embodiment of the present application will be described in detail below with reference to a specific embodiment. In this embodiment, taking the terminal device shown in fig. 2 as an example, the terminal device includes a first antenna system and a second antenna system, where the first antenna system is a WiFi system, and the second antenna system is a cellular system; further, the first antenna system comprises two first antennas, namely a WiFi antenna 1 and a WiFi antenna 2; the first antenna system comprises 4 second antennas, namely an antenna 1 to an antenna 4.
The terminal equipment is started to operate, the WiFi antenna 1 or 2 in the first antenna system executes WiFi communication, and the antenna 3 or 4 in the second antenna system executes cellular communication. At this time, the first configuration information corresponding to the first antenna system includes a first frequency (f1) and a first bandwidth (BW1), and the second configuration information corresponding to the second antenna system includes a second frequency (f2) and a second bandwidth (BW 2). In this example, f1 is 2460MHz and BW1 is 20M, f2 is 2570MHz and BW2 is 10 MHz.
The processor of the terminal device obtains the first frequency configuration information and the second frequency configuration information, i.e. obtains the above configuration information of f1, BW1 and f2, BW2, etc. The processor of the terminal device may include two processing modules, which respectively correspond to the two communication systems, and may include two processing modules, and one of the processing modules, for example, the first processing module, acquires the configuration information f2, BW2 of the other processing module, for example, the second processing module, through bus transmission.
And the first processing module searches the target antenna in at least one preset frequency relation table according to the configuration information. That is, for the cellular network system, one second frequency band range may correspond to a plurality of relationship tables, in this embodiment, 3 frequency relationship tables are illustrated, which are table 3 to table 5 respectively.
TABLE 3
TABLE 4
TABLE 5
Tables 3 to 5 show the correspondence of at least one second antenna with the first frequency range at different second frequency ranges (1 to 3). Specifically, the second frequency range 1 in table 3 is [2496, 2550 ], the second frequency range 2 in table 4 is [2550, 2630 ], and the second frequency range 3 in table 5 is [2630, 2690], respectively. Wherein "[" and "]" means including an end value or a critical value, and "(" and ")" means not including an end value or a critical value. The first frequency range comprises 3 different frequency ranges, respectively: the first frequency range 1 is [2412, 2445 ], the first frequency range 2 is [2445, 2475 ], the first frequency range 3 is [2475, 2484 ].
The step 102 specifically includes: the second processing module corresponding to the second antenna system first determines whether interference is generated with the first antenna system according to the first frequency f1 and the second frequency f2, that is, whether f1 is located in the first frequency range [2412,2484] in tables 3 to 5, and whether f2 is located in the second frequency range [2496, 2690 ]; after the judgment, f 1-2460 MHz and f 2-2570 MHz are both located in the first frequency range and the second frequency range, so that interference is generated. Then, the "frequency relation table" of table 4 is specifically determined as the relation table for determining the target antenna according to f1 and f2, because f2 in the second frequency configuration information is located in the second frequency range 2[2550, 2630) in table 4. Finally, the second antenna with "antenna 1/2/3" as a candidate is determined according to the correspondence between BW1 and BW2, which are 20MHz and 10MHz in table 4, and then any one of the antennas "antenna 1/2/3" is selected as the target antenna, and "antenna 1" is selected as the target antenna in this embodiment.
Therefore, with the method of the present embodiment, cellular communication is performed using the antenna 1 for the second antenna system, and WiFi communication is performed using the WiFi antenna 1 and the WiFi antenna 2 for the first antenna system, and since the isolation between the antenna 1 selected for the second antenna system and the first antenna system is large, interference does not occur between the first antenna system under the operation of the first frequency and the first bandwidth and the second antenna system under the operation of the second frequency and the second bandwidth, and concurrent coexistence of the two antenna systems is achieved.
In this embodiment, a process of using the frequency relationship table to select the target second antenna for use when the second antenna in the second antenna system interferes with the first antenna system is illustrated, so as to avoid interference with the first antenna system. It is understood that the method may further include a method flow of selecting and using the target first antenna when the first antenna system determines that the first antenna system interferes with the second antenna system, so as to avoid interference with the two antenna systems.
Specifically, the process of the first antenna system selecting a target first antenna and switching and using is similar to the foregoing embodiment, except that the second antenna used in the second antenna system is not changed, and the first antenna in the first antenna system needs to be determined and switched according to the "frequency relation table". The frequency relationship table is shown in table 6 below, and similar to table 2 of the above embodiment, it is needless to say that other more table relationships may be included, which is not limited in this embodiment.
TABLE 6
In addition, when the first antenna system and the second antenna system determine whether the operating frequency and bandwidth thereof interfere with the other system, the priorities of the two systems are also considered. For example, if the priority of the cellular network system is lower than that of the WiFi system, the transmission power of the cellular system needs to be reduced, and then matching is performed according to the correspondence in tables 3 to 5, and the corresponding operating frequency range and bandwidth information, and the selectable antenna combination applicable to the first antenna system are searched.
Specifically, for setting the priority among the antenna systems, when the terminal device is concurrently operating in the cellular network system and the WiFi system, if the cellular network system and the WiFi system are operating simultaneously and generate mutual interference, priority processing of emergency services is required to be guaranteed, or the priority of the cellular network system and the WiFi system is set on the principle that the influence on user experience is minimal, in the service scenarios of the above tables 3 to 5, when the cellular network system and the WiFi system interfere with each other, the priority of the WiFi system may be set higher than the cellular network, so as to guarantee that the service of the WiFi system communication is preferentially executed.
In the method provided by this embodiment, the processing module corresponding to the antenna system of the cellular network determines that interference occurs between the two systems by using the acquired frequency and bandwidth information and the operating frequency and bandwidth information reported by the processing module corresponding to the WiFi antenna system, and selects the target antenna for selection or switching, so that the isolation of the selected or switched antenna combination is higher, thereby avoiding mutual interference between the two antenna systems, achieving the beneficial effect of concurrent coexistence of the cellular network and the WiFi network, and ensuring the user experience of the terminal product. It is to be understood that handover is a special case of antenna selection, i.e. stopping the use of the original antenna and instead using the selected new antenna to perform the communication service.
Referring to fig. 5, an antenna selection apparatus 500 is provided for the present embodiment, and is used to implement the method in the foregoing embodiments. Specifically, as shown in fig. 5, the apparatus includes: an obtaining unit 501, configured to obtain first frequency configuration information and second frequency configuration information, where the first frequency configuration information corresponds to a first antenna system of a first communication system, the second frequency configuration information corresponds to a second antenna system of a second communication system, the first antenna system includes at least one first antenna, the second antenna system includes at least one candidate second antenna, and the second communication system is different from the first communication system.
