Description

Antenna selection method, terminal and medium

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a method, a terminal and a medium for selecting an antenna.

Background

With the development of communication technology, a terminal can support multiple antennas, that is, the terminal can select a part or all of multiple antennas to transmit/receive signals simultaneously according to the signal quality of each antenna, thereby enhancing the signal transmission capability of the terminal. The antenna is generally disposed at a side of the terminal or at a back cover of the terminal in consideration of an exterior design of the terminal. However, during the use of the terminal, the position of the terminal and the use habit of the user often affect the signal quality of the antenna, for example, the terminal placed on the bracket may be shielded by the bracket; the user holds the terminal with both hands to watch a video or play a game, and the side antenna is shielded by the fingers. At this time, the terminal needs to detect the signal quality of each antenna one by one and select an antenna with better signal quality to transmit/receive signals. However, as the number of antennas increases, the process of detecting the signal quality of each antenna by the terminal becomes more and more time consuming, and causes additional performance overhead to the terminal, thereby affecting the user experience.

Detailed Description

Embodiments of the present application include, but are not limited to, an antenna selection method, a terminal, and a medium.

In order to facilitate understanding of the technical solutions of the present application, the following explains the technical terms related to the technical solutions of the embodiments of the present application.

1. Terminal transceiver frame, TX channel, RX channel, 1T4R, 2T4R

Fig. 1a is a schematic structural diagram of a terminal transceiver frame according to an embodiment of the present application. As shown in fig. 1a, the transceiving frame of the terminal may be divided into three parts of baseband, radio Frequency (RF) and antenna. The baseband may include a modem (modem) module for processing the baseband signal. The radio frequency may include a radio frequency integrated circuit (radio frequency integrated circuit, RFIC) and a radio frequency front end (radio frequency front end, RFFE) for processing radio frequency signals. The antenna is used for receiving signals or transmitting signals.

The terminal has a TX (transmit) channel for transmitting data and an RX (receive) channel for receiving data. The TX channel and the RX channel may be further refined because of the different locations. For example, a TX channel located in the radio frequency part may be referred to as a radio frequency transmit channel, and an RX channel located in the radio frequency part may be referred to as a radio frequency receive channel.

The number of TX channels and the number of RX channels in the terminal are not limited in the embodiment of the present application.

1T4R means that there are 1 TX channels and 4 RX channels. For example, as shown in FIG. 1a, 1 TX channel is labeled TX1 and 4 RX channels are labeled RX1 through RX4.

2T4R means that there are 2 TX channels and 4 RX channels. For example, as shown in FIG. 1b, 2 TX channels are labeled TX 1-

TX

2, and 4 RX channels are labeled RX 1-RX 4.

The number of the antennas in the terminal is not limited in the embodiment of the application. At present, the terminal can support various frequency bands in 2G-5G communication, and different frequency bands can correspond to different antennas. The number of antennas in each frequency band is not limited in the embodiment of the present application. For convenience of explanation, the embodiment of the present application uses 8 antennas as examples. A terminal with 8 antennas may be referred to as an 8 antenna terminal. A terminal with 8 antennas, 1T4R is called a 1T4R/8 antenna terminal. A terminal with 8 antennas, 2T4R, is called a 2T4R/8 antenna terminal.

2. Correspondence between TX channel, RX channel and antenna

In one embodiment of the present application, 1 TX channel corresponds to 1 antenna and 1 RX channel corresponds to 1 antenna.

For A1T 4R/8 antenna terminal, as shown in fig. 2a, TX1 corresponds to antenna A1 (solid line in the figure), and RX1 to RX4 correspond to antennas A1 to A4, respectively (broken line in the figure). The antenna corresponding to TX1 is not limited in this embodiment of the present application. For example, TX1 may also correspond to antenna A2.

In another embodiment of the present application, 1 TX channel may also correspond to 2 antennas, and 1 RX channel may correspond to 2 antennas. Illustratively, as shown in fig. 2B, TX1 corresponds to antennas A1 and B1, RX1 corresponds to antennas A1 and B1, it being understood that RX2 may correspond to antennas A2 and B2, RX3 may correspond to antennas A3 and B3, and RX4 may correspond to antennas A4 and B4.

In another embodiment of the present application, for a 2T4R/8 antenna terminal, as shown in fig. 3a, TX1 corresponds to antenna A1, TX2 corresponds to antenna A3, and RX0 to RX3 correspond to antennas A1 to A4, respectively. The antenna corresponding to each of TX1 and TX2 is not limited in this embodiment of the present application. For example, TX1 corresponds to antenna A2, TX2 corresponds to antenna A4; alternatively, TX1 corresponds to antenna A1 and TX2 corresponds to antenna A2.

In another embodiment of the present application, for a 2T4R/8 antenna terminal, one of the 2 TX channels may correspond to 2 antennas. For example, as shown in fig. 3B, TX1 corresponds to antennas A1 and B1, TX2 corresponds to antennas A3 and B3, and RX1 to RX4 correspond to antennas A1 to A4, respectively. The antenna corresponding to TX1 and TX2 is not limited in this embodiment of the present application.

In the embodiment of the application, the 1T4R/8 antenna terminal and the 2T4R/8 antenna terminal can support a maximum of 4 antennas for receiving signals.

3. Antenna Gain (Gain value), phase (Phase)

The antenna gain refers to the gain in each direction generated by the antenna, and is used to measure the signal quality of the antenna for transmitting and receiving signals in a specific direction, and the unit is dBi, dBd or dB. As represented by the antenna pattern, the narrower the main lobe of the radiation of the antenna in the pattern, the smaller the side lobe, and the higher the gain.

The phase refers to the radiation angle of the antenna. The antenna gain and phase may form an antenna pattern.

Having described terms of art to which embodiments of the present application relate, a scene diagram of a communication system 10 to which embodiments of the present application are applicable is described below with reference to fig. 4.

As shown in fig. 4, the terminal 100 communicates with the network device 200, the terminal 100 transmits data to the network device 200, and the network device 200 receives the data transmitted by the terminal 100; accordingly, the network device 200 transmits data to the terminal 100, and the terminal 100 receives the data transmitted by the network device 200.

The name and type of the terminal 100 are not limited in the embodiment of the present application. A terminal may also be referred to as an electronic device, a terminal device, a User Equipment (UE), a Mobile Terminal (MT), etc., which is a device that provides voice/data connectivity to a user. Examples of some terminal devices are: a mobile phone, tablet, notebook, palm, wearable device, mobile internet device (mobile internet device, MID), virtual Reality (VR) device, augmented reality (augmented reality, AR) device, wireless terminal in self-driving (self-driving), or wireless terminal in smart home (smart home), etc.

The name and type of the network device 200 are not limited in the embodiments of the present application. A network device is a means for transmitting and receiving signals, e.g. a radio access network (radio access network, RAN) node that accesses a terminal to a wireless network. Currently, examples of some network devices are: a new generation base station (generation Node B, gNB), a transmission reception point (transmission reception point, TRP), an evolved Node B (eNB), or a relay station in the 5G system.

Fig. 5a and 5b show a block diagram of a transceiving frame 1001 of a terminal 100 according to a scenario of an embodiment of the present application described in fig. 4. As shown in fig. 5a, the terminal 100 may have 8 antennas, and antennas 1 to 8,8 antennas may be located at the back cover and side of the terminal 100. As shown in fig. 5b, the baseband 10011 of the terminal 100 may sequentially select 1 antenna with signal quality meeting a preset condition from the antennas 1 to 8 through the radio frequency switch 100121, for receiving or transmitting signals. The preset condition here may be to select an antenna with the best signal quality from among the antennas. It can be seen that although the terminal 100 can receive or transmit signals using antennas whose signal quality meets a preset condition, for the terminal 100 having 8 antennas, the terminal 100 intelligently selects 1 antenna among them to transmit/receive signals, and does not make full use of the antennas.

Fig. 6a and 6b are structural diagrams of a transceiving frame 1001 of another terminal 100, compared to fig. 5a and 5 b. As in fig. 5a, the type of terminal 100 may be a non-folding mobile phone, the terminal 100 may have 8 antennas, and antennas 1 to 8,8 may be located at the back cover and side of the terminal 100. The baseband 10011 of the terminal 100 may sequentially select a plurality of antennas with signal quality meeting a preset condition from the antennas 1 to 8 through the demultiplexer 100122, for example: antennas 1 to 4 for receiving or transmitting signals. It can be seen that, in the embodiment of the present application shown in fig. 6a, the transceiver frame 1001 of the terminal 100 may select an antenna combination with signal quality meeting a preset condition to receive or transmit a signal. Therefore, in different scenarios, the transceiver frame 1001 of the terminal 100 may use different antenna combinations to achieve the best antenna combination in the scenario, so as to improve the signal transmission capability of the terminal 100. It can be seen that, in the embodiment of the present application shown in fig. 6a and fig. 6b, the terminal 100 performs signal quality detection on each antenna and selects the antenna with the signal quality meeting the preset condition to combine, so as to select the best antenna combination.

However, in the embodiment of the present application shown in fig. 6b, in order that the antenna gains of the antennas 1 to 4 may be superimposed to improve the signal transmission capability of the terminal 100 through beamforming, the antennas 1 to 4 may be disposed at one side of the terminal 100, that is, in a range where the sides of the antennas 1 to 4 are disposed, the signal transmission capability of the terminal 100 is stronger, and in other ranges, the terminal 100 may be in a weak transmission region, and if the sides where the antennas 1 to 4 are disposed are shielded, the signal transmission capability of the whole terminal 100 may be affected. Meanwhile, as the number of antennas included in the terminal 100 increases, if the antennas of the terminal are not screened first, but signal quality detection is directly performed on the antennas of the terminal and antenna pattern analysis is performed on an antenna combination composed of the antennas, the amount of computation in the above process increases greatly. For example, taking a terminal with 1T4R/8 antennas as an example, it is necessary to determine a set of antenna combinations including 1 to 4 antennas from 8 antennas, and then perform antenna pattern analysis on each antenna combination in the set, and further screen out an antenna combination that meets an antenna pattern value threshold (where the antenna pattern value threshold may represent that an antenna pattern value of the antenna combination is the largest). This may make the process of screening the antenna combinations by the terminal 100 more and more time consuming, thereby reducing the efficiency of determining the optimal antenna combination by the terminal 100.

In order to solve the problem that the process of determining the optimal antenna combination by the terminal is more and more time-consuming, some embodiments of the present application provide an antenna selection method, which includes: the terminal divides each antenna into a plurality of antenna areas according to the position of each antenna configured at the terminal; before the terminal performs signal quality detection on each antenna and screens out the antennas meeting the preset conditions, the terminal can determine a target antenna area from a plurality of antenna areas, wherein the target antenna area can be an unmasked antenna area or an antenna area corresponding to the incoming wave direction of the network equipment. Wherein, the antenna area that is not shielded may mean that the antenna area is not shielded by a shielding object or the terminal itself, for example: for a mobile phone horizontally placed on a desktop, the back cover area of the mobile phone can be a shielded antenna area, and the side edge of the mobile phone can be an unshielded antenna area; the antenna area corresponding to the incoming wave direction of the network device may refer to a direction of an antenna of the antenna area facing the incoming wave direction of the network device.

If a target antenna area exists, the terminal can ignore the antennas contained in other antenna areas, namely, the terminal does not detect the signal quality of the antennas contained in the antenna areas outside the target antenna area, but only detects the signal quality of the antennas contained in the target antenna area, selects the antennas with the signal quality meeting the preset condition from the antennas contained in the target antenna area to be combined, namely, acquires a set of antenna combinations with the signal quality meeting the preset condition, screens out the optimal antenna combinations in a polling mode from the set, and finally synthesizes the synthesized field pattern of the antennas through the optimal antenna combinations.

In the embodiment of the application, the terminal may also use the RX channels to perform signal quality detection on each antenna at the same time. For example, the target antenna area determined by the terminal includes 4 antennas, antennas A1 to A4; the terminal has 4 receiving channels from RX1 to RX4, and the terminal can switch the antennas A1 to A4 to be connected with the antennas RX1 to RX4 at the same time, and detect the signal quality of the antennas A1 to A4 through the antennas RX1 to RX4 to determine that the signal quality meets the preset condition. Compared with a method of performing signal quality detection on the antennas A1 to A4 respectively through only a single reception channel, the number of times of switching transmission paths between the terminal and each antenna can be reduced. The method of the embodiment of the application improves the efficiency of determining the optimal antenna combination by the terminal and reduces the performance cost of the terminal.

It may be understood that in the embodiment of the present application, the method for dividing each antenna of the terminal into the antenna areas may be to divide each antenna into the antenna areas corresponding to the positions according to the positions where each antenna is configured in the terminal. For example, fig. 7 shows a structural diagram of an antenna of the terminal 100 adopting the above method. As shown in fig. 7, the terminal 100 may be A1T 4R/8 antenna terminal, and the type of the terminal 100 may be a non-folding mobile phone, which has 8 antennas, antennas A1 to A4 and antennas B1 to B4, the antennas A1 to A4 being disposed at the side of the terminal 100, and the antennas B1 to B4 being disposed at the back cover of the terminal 100. The terminal 100 may divide the antennas A1 to A4 into the antenna area-1, that is, the side antenna area; the antennas B1 to B4 are divided into an antenna area-2, that is, a back cover antenna area.

In the embodiment of the present application, after the terminal 100 divides the antennas A1 to A4 and the antennas B1 to B4 into the antenna area-1 and the antenna area-2, if the terminal 100 is placed on the stand, the terminal 100 may detect that the back cover of the terminal 100 is shielded by the stand through the SAR sensor/proximity sensor, in this case, the terminal 100 ignores the back cover antenna area, that is, the antennas B1 to B4 of the antenna area-2, but detects the signal quality of the antennas A1 to A4, and selects the antennas with signal quality meeting the preset condition to combine, thereby screening out the optimal antenna combination.

After the structure of the antenna applied to the terminal according to the embodiment of the present application is described through fig. 7, a method for selecting the antenna of the terminal according to the embodiment of the present application will be described in detail through fig. 8. Fig. 8 is a flowchart illustrating an antenna selection method according to an embodiment of the present application, where the method is applied to a terminal 100, and the terminal 100 may be a 1T4R/8 antenna terminal, and the antenna selection method includes, but is not limited to, steps S801 to S806, where:

s801: the terminal 100 divides each of the antennas that it has into a plurality of antenna areas.

The terminal 100 divides each antenna into a plurality of antenna areas according to the position where each antenna is arranged in the terminal 100.

The following description takes a mobile phone with a 1T4R/8 antenna as an example of the terminal 100, and fig. 9 shows a structure diagram of an antenna of the terminal 100 to which another embodiment of the present application is applied. As shown in fig. 9, the type of the terminal 100 may be a non-folder phone, and the terminal 100 may have 8 antennas, and the 8 antennas are divided into an antenna area-1: antennas A1 to A4 and an antenna area-2: antenna B1-antenna B4, wherein antenna area-1 is located at the side of terminal 100 and antenna area-2 is located at the back cover of terminal 100. Referring to the structure of the antenna of the terminal 100 shown in fig. 7, for the antennas A1 to A4 included in the antenna area-1, the positions of the antennas A1 to A4 located at the sides of the terminal 100 may also include three cases, where the antennas A1 to A4 are located at each side of the terminal 100 and the antennas A2 and A3 are not located on the same horizontal line; the antennas A1 to A4 are respectively positioned on each side of the terminal 100, and the antenna A2 and the antenna A3 are positioned on the same horizontal line; the antenna A1 and the antenna A4 are located at one side of the mobile phone 100 at the same time.

S802: the terminal 100 determines whether there is an unmasked antenna area.

If the terminal 100 detects that one of the plurality of antenna areas is not shielded, and the other antenna areas are shielded antenna areas, since the antennas in the shielded antenna areas are affected by shielding, the signal quality of the antennas is poor, and at this time, S803 is performed, the terminal 100 may exclude the antenna areas other than the non-shielded antenna areas, and only need to measure the signal quality of each antenna that the non-shielded antenna areas have, and select the antenna with better signal quality from the non-shielded antenna areas to form a target antenna combination, and receive or transmit signals through the target antenna combination. If the terminal 100 detects that there are a plurality of non-shielded antenna areas among the plurality of antenna areas, or the plurality of antenna areas are all shielded antenna areas, since the terminal 100 cannot primarily exclude antenna areas with poor signal quality of the antennas through S802, the terminal 100 performs S804 to measure the signal quality of each antenna, selects the antenna with better signal quality, forms a target antenna combination, and receives or transmits signals through the target antenna combination.

In the embodiment of the present application, the terminal 100 may determine whether each of the antenna areas determined in step S801 is shielded by the shielding object or the terminal itself, if so, the antenna area is a shielded antenna area, and if not, the antenna area is an unshielded antenna area. The terminal 100 may determine whether one antenna area is shielded by the SAR sensor (Specific Absorption Ratio, specific absorption rate)/proximity sensor. The SAR sensor is used to detect electromagnetic radiation energy absorbed by an object of unit mass per unit time, i.e., the closer the terminal 100 is to the object, the greater the electromagnetic radiation energy absorbed by the object. Proximity sensors are used to identify the proximity of an object by a change in a physical characteristic of the approaching object, for example, by refraction and reflection of light. In the embodiment of the present application, taking the terminal 100 shown in fig. 7 as an example, for example, the user places the terminal 100 on a stand to play a movie with the terminal 100, the terminal 100 may determine that the antenna area-2 (back cover antenna area) of the terminal 100 in fig. 7 is shielded by the stand as a shielded antenna area, and the antenna area-1 (side antenna area) is an unshielded antenna area through the SAR sensor/proximity sensor. For another example, when the user holds the terminal 100 with both hands to play a game, the antenna area-1 (side antenna area) of the terminal 100 is shielded by the finger as a shielded antenna area, and the antenna area-2 (back cover antenna area) is an unshielded antenna area.

S803: the terminal 100 measures signal quality of each antenna that the non-shielded antenna area has.

In the embodiment of the present application, the terminal 100 may detect signal quality of each antenna that the terminal 100 has through the transceiving frame 1001. Fig. 10 is a schematic structural view of a transceiver frame 1001 of the terminal 100. As shown in fig. 10, the transceiver frame 1001 includes: the baseband 10011, the radio frequency circuit 10012 and the radio frequency front end 10013, the radio frequency front end 10013 includes a lossy multiplexer 100131 and an antenna path selector 100132. The antenna path selector 100132 is disposed between the antenna and the variable-loss multiplexer 100131, and may be a circuit module composed of a plurality of radio frequency switches, and determines transmission paths between the TX channel and the RX channel and the antenna by switching the radio frequency switches.

Either the baseband 10011 or the radio frequency circuit 10012 may control the antenna path selector 100132 to switch the TX channel and the RX channel and the transmission paths between the antennas, and obtain the signal quality of each antenna, that is, the antenna gain and phase, through the RX channel and each antenna, to determine the antenna meeting the preset condition.

The variable loss multiplexer 100131 is disposed between the baseband 10011 and the antenna path selector 100132, and is configured to determine a target antenna combination from the antennas determined by the baseband 10011 and meeting the preset conditions, and the terminal 100 receives or transmits signals through the target antenna combination.

Taking step S802 to determine that the antenna area-1 is an unshielded antenna area as an example, as shown in fig. 10, the transmit channel TX1 and the receive channel RX1 are connected to the antenna A1 of the antenna area-1 through the impairment multiplexer 100131 and the antenna path selector 100132. The reception channels RX2 to RX4 are connected to the antennas A2 to A4 through the antenna path selectors 100132, respectively, and the baseband 10011 may obtain the signal qualities, i.e., the antenna gains and phases, of the antennas A1 to A4 through the reception channels RX1 to RX4, respectively.

S804: the terminal 100 measures signal quality of each antenna that the plurality of antenna areas have.

In the embodiment of the present application, for example, a user holds the terminal 100 with one hand to make a call, the side antenna area of the terminal 100 may be shielded by the user's finger, and the back cover antenna area of the terminal 100 may be shielded by the user's palm. Since the terminal 100 fails to exclude a part of antennas with poor signal quality through step S802, the terminal 100 needs to measure the signal quality of each antenna that it has. Taking the transceiver frame 1001 of the terminal 100 with 1T4R/8 antennas as an example, the receiving channels RX1 may be connected to the antennas A1 to A4 and the antennas B1 to B4 through the variable loss multiplexer 100131 and the antenna path selector 100132, and the receiving channels RX2 to RX4 may be connected to the antennas A1 to A4 and the antennas B1 to B4 through the antenna path selector 100132, and the baseband 10011 obtains the signal qualities of the antennas A1 to A4 and the antennas B1 to B4 through the receiving channels RX1 to RX4, respectively.

In the embodiment of the present application, fig. 11 shows a structure diagram of a variable multiplexer 100131 and an antenna path selector 100132 of a transceiver frame 1001 of A1T 4R/8 antenna terminal 100, where the antenna path selector 100132 includes four switches, namely, a switch 1 to a switch 4, and the switch 1 may be a Single-Pole Two-Throw (SP 2T) switch for switching an antenna A1 and an antenna B1 connected to a receiving channel RX 1; the switches 2 to 4 may be DPDT switches (Double-Pole Double-Throw), and taking the switch 2 as an example, the switch 2 may connect the receiving channel RX2 to the antenna A2 or the antenna B2, respectively, and for the receiving channel RX2, the switch 2 is used to switch the antenna A2 and the antenna B2 connected to the receiving channel RX 2; it will be appreciated that the switch 3 and the switch 4 may connect the receive path RX3 and the receive path RX4 to the antenna A3 or the antenna B3 and the antenna A4 or the antenna B4, respectively. The switches 2 to 4 may also connect the variable-loss multiplexer 100131 to the antennas A2 to A4 or the antennas B2 to B4, where the variable-loss multiplexer 100131 obtains the signals from the antennas A1 to A4 or the antennas B1 to B4, and performs a field pattern feature analysis on the signals to determine a target antenna combination with the best signal quality.

The variable loss multiplexer 100131 may include a switch provided with four channels a-B, and each channel may establish a transmission path with 4 antennas among the 8 antennas, that is, antennas A1 to A4 and antennas B1 to B4, respectively, and perform field type feature analysis on signals of the antennas corresponding to the four channels to determine a target antenna combination.

For example: when each antenna is the antennas A1 to A4, the switch 1 may be switched to the antenna A1, and the reception channel RX1 is connected to the antenna A1 through the loss multiplexer 100131; the switches 2 to 4 may be switched to the antennas A2 to A4 such that the reception channels RX2 to RX4 are connected to the antennas A2 to A4. The baseband 10011 may acquire signal qualities of the antennas A1 to A4 through the reception channels RX1 to RX 4.

S805: the terminal 100 selects an antenna meeting a preset condition according to the signal quality of each antenna.

In the embodiment of the present application, the preset condition may be preset in a storage area of the terminal 100, for example: in the memory, the signal quality threshold of the antenna is set, and after acquiring the signal quality of each antenna, the transceiver frame 1001 of the terminal 100 selects an antenna whose signal quality is higher than the signal quality threshold.

Taking step S802 to determine that the antenna area-1 is an unmasked antenna area as an example, the baseband 10011 of the transceiver frame 1001 may sequentially obtain the signal qualities of the antennas A1 to A4, for example: antenna gain and phase are, respectively, antenna A1: the antenna gain is-3.55 dB, and the phase is 170 degrees; antenna A2: the antenna gain is-4.49 dB, and the phase is 0 degree; antenna A3: the antenna gain is-3.28 dB, and the phase is 0 degree; antenna A4: the antenna gain is-3.12 dB and the phase is 0 deg.. When the preset condition is-5 dB, the baseband 10011 of the transceiver frame 1001 may determine that the antennas A1 to A4 are antennas that meet the preset condition.

It will be appreciated that the values of the signal quality of the antennas A1 to A4 are exemplary, and that in another embodiment of the present application, the values of the signal quality of the antennas A1 to A4 may take other values.

S806: the terminal 100 screens antennas meeting preset conditions, determines a target antenna combination, and receives or transmits signals through the target antenna combination.

In the embodiment of the present application, the terminal 100 may traverse the set of antenna combinations formed by the antennas selected in step S805 in a polling manner, compare the composite benefits of the antenna combinations, determine an optimal antenna combination as a target antenna combination, and generate a composite field pattern through the synthesis of the target antenna combination. For example: step S805 determines antennas A1 to A4, and each antenna combination of antennas A1 to A4 may include: 1 to 4 antennas A1 to A4. According to the signal quality corresponding to the synthesized field type generated by synthesizing the antenna combinations, a target antenna combination with the best signal quality is determined, so that the signal transmission capability of the terminal 100 is optimal.

In the embodiment of the present application, the impairment multiplexer 100131 of the transceiver frame 1001 of the terminal 100 may perform a pattern feature analysis on the signal quality of the combination of the antennas to determine a target antenna combination with the best signal quality. Fig. 12a and 12b show a schematic diagram of a impairment multiplexer 100131 performing a pattern analysis of the combined signal quality of the antennas. Taking the signal quality of the antennas A1 to A4 selected in step S805 as an example, fig. 12a shows the pattern characteristics of each of the antennas A1 to A4, and fig. 12b shows the pattern characteristics of the antenna combination of the antennas A1 to A4 and the pattern characteristics of the antenna combination of the antennas A2 to A4, it can be seen that the antenna pattern values of the antenna combination of the antennas A1 to A4, namely: the antenna gain is-9 dB, and the antenna pattern value of the antenna combination of the antennas A2 to A4 is-0.94 dB. As can be seen from fig. 12a and 12b, due to the phase difference between the antenna A1 and the antennas A2 to A4, so that there is a destructive property between the antenna A1 and the antennas A2 to A4, the baseband 10011 can determine that, among the set of antenna combinations made up of the antennas A1 to A4, the antenna combination that meets the threshold value of the antenna pattern value is the antennas A2 to A4, that is, the antenna pattern value of the antenna combination made up of the antennas A2 to A4 is the largest, that is, the antennas A2 to A4 are the target antenna combinations.

Figures 8 to 12a and 12b above describe the practice of the present applicationIn the embodiment, the transceiver frame 1001 of the terminal 100 determines the antenna area of each antenna of the terminal 100 and selects the target antenna combination from the antenna area that is not shielded to receive or transmit the signal, and in the case where the terminal 100 is a terminal of 1T4R/8 antennas (antennas A1 to A4 and antennas B1 to B4), in the embodiment of the present application, if the scheme described in fig. 8 is not used, the transceiver frame 1001 of the terminal 100 may indicate that the transmission path is turned on and 0 indicates that the transmission path is not turned on by using fig. 13a and 13B according to the antenna combinations that can be determined between each antenna and the TX channel and the RX channel, and in fig. 13a and 13B, the value 1 indicates that the transmission path is turned on. It can be seen that for the terminal of 1T4R/8 antennas shown in fig. 11, it is necessary to determine one set of antenna combinations including 1 to 4 antennas from among 8 antennas, and taking an antenna combination including 2 antennas as an example, these 2 antennas cannot be 2 antennas connected to the same switch, as the antennas A1 and B1 shown in fig. 11. Similarly, for an antenna combination including 3 antennas, any 2 antennas in the antenna combination cannot be 2 antennas connected to the same switch, such as the antennas A1, B1, and A2 shown in fig. 11. Thus, for the terminal of 1T4R/8 antennas shown in fig. 11, the method for determining a set of antenna combinations including 1 to 4 antennas from 8 antennas may be, taking an antenna combination including 1 antenna as an example, the number of antenna combinations including 1 antenna is

I.e. 8, the number of antenna combinations comprising 2 antennas is +.>

But excluding 2 antennas connected to the same switch, it may be determined that the number of antenna combinations including 2 antennas is 24, and so on, as shown in fig. 13a and 13b, the transceiving frame 1001 of the terminal 100 may determine that 80 antenna combinations exist, and the transceiving frame 1001 of the terminal 100 may determine one target antenna combination from among the 80 antenna combinations, through which signals are received or transmitted.

In an embodiment of the present application, in addition to the description of step S802 of fig. 8, the terminal 100 may select one target antenna combination among the antennas of the non-shielded antenna areas by determining the non-shielded antenna areas among the plurality of antenna areas, and a scheme of receiving or transmitting signals through the target antenna combination; fig. 14a to 14c also show a scenario diagram (scenario 1 to scenario 3) in which the terminal 100 determines an antenna area corresponding to an incoming wave direction through an incoming wave direction, and selects one target antenna combination from among antennas of the antenna area corresponding to the incoming wave direction, and receives or transmits a signal through the target antenna combination, where the incoming wave direction may be a signal direction of the network device, and the antenna area corresponding to the incoming wave direction may be a direction of an antenna of the antenna area facing the incoming wave direction of the network device. Fig. 14a shows a position where the incoming wave direction is the antenna area-2, that is, the back cover of the terminal 100, and the terminal 100 may determine that the antenna area corresponding to the incoming wave direction is the antenna area-2. Fig. 14b shows a screen in which the incoming wave direction is the terminal 100, and the terminal 100 may determine an antenna area corresponding to the incoming wave direction as the antenna area-1. Fig. 14c shows that the incoming wave direction is a side of the terminal 100, and the terminal 100 may determine an antenna area corresponding to the incoming wave direction as an antenna area-1. It can be seen that, in the scenario of fig. 14a to 14c, as shown in fig. 15, in the scenario described in fig. 14a to 14c, after determining the antenna region corresponding to the incoming wave direction, the terminal 100 may determine the target antenna combination from among 15 antenna combinations of each antenna in the antenna region, compared with 80 antenna combinations shown in fig. 13a and 13b, which reduces the amount of computation of the signal quality detection and combination analysis performed by the terminal 100 on each antenna.

Fig. 8 to 12a and 12b describe the scheme that in the embodiment of the present application, the transceiver frame 1001 of the terminal 100 determines the antenna areas of the antennas of the terminal 100 and selects the target antenna combination to receive or transmit the signal from the unshielded antenna areas, and the loss multiplexer 100131 of the transceiver frame 1001 in the embodiment of the present application is described below through fig. 16a and 16 b.

The variable loss multiplexer 100131 can be switched on with multiple transmission paths between the antennas through the switch 100131-1, and signal quality corresponding to the antenna combination of each antenna is different according to the number of the switched on transmission paths, and the variable loss multiplexer 100131 determines an antenna combination with the best signal quality, where the signal quality corresponding to the different antenna combinations can be represented by a difference loss.
