Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, a first base station may be referred to as a second base station, and similarly, a second base station may be referred to as a first base station, without departing from the scope of the present application. The first base station and the second base station are both base stations, but they are not the same base station.

Referring to fig. 1, a schematic diagram of a network system architecture according to an embodiment of the present application is shown. In the system architecture shown in fig. 1, the client premise equipment 10 may be connected to a first base station 20 in a first network system and access a core (core) network through the first base station 20. The customer premises equipment 10 is used for realizing a network access function, converting an operator public network WAN into a user home local area network LAN, and supporting a plurality of mobile customer premises equipment 10 to access the network. In addition, the vicinity of the customer premises equipment 10 may be also deployed with a cell of the second network system and a second base station, or may not be deployed with a cell of the second radio frequency system and a second base station. The first network system is different from the second network system, for example, the first network system may be a 4G system, and the second network system may be a 5G system; alternatively, the first network system may be a 5G system and the second network system may be a future PLMN system evolved after 5G; the embodiment of the present application does not specifically limit what kind of radio frequency system the first network system and the second network system specifically belong to.

When the customer premises equipment 10 is connected to the 5G communication system, the customer premises equipment 10 may transmit and receive data to and from a corresponding base station through a beam formed by the 5G millimeter wave antenna module, and the beam needs to be directed to an antenna beam of the base station, so as to facilitate the customer premises equipment 10 to transmit uplink data to the base station or receive downlink data transmitted by the base station.

The customer premises equipment 10 is used to implement a network access function to convert the operator public network WAN to the user home local area network LAN. According to the current internet broadband access mode, the access modes can be classified into FTTH (fiber to the home), DSL (digital telephone line access), Cable (Cable television line access), and Mobile (Mobile access, i.e. wireless CPE). The client front-end device is a mobile signal access device which receives mobile signals and forwards the mobile signals as wireless WIFI signals, and is also a device which converts high-speed 4G or 5G signals into WiFi signals and can support a plurality of mobile terminals 30 to access a network.

Referring to fig. 2 and 3, in an embodiment, the client front-end device 10 includes a main body portion including a housing 11 and a circuit board 12, and the client front-end device 10 further includes a radio frequency system 13 disposed in the main body portion. Further, in the present embodiment, the main body portion of the client premises equipment 10 may be understood as a structure other than the radio frequency system 13. The housing 11 forms a mounting cavity in which the circuit board 12 and the radio frequency system 13 are mounted and supported, positioned and protected by the housing 11. In the embodiment shown in fig. 2, the housing 11 is substantially cylindrical, and the external appearance of the customer premises equipment 10 is mainly presented by the housing 11. In other embodiments, the housing 11 may take on other shapes such as a prism shape, etc. Referring to fig. 4, the length of the circuit board 12 is the same as the length of the housing 11, and the rf system 13 is electrically connected to the circuit board 12. The circuit board 12 is provided with a plurality of interfaces 23 exposed to the housing 11, and the interfaces 23 are electrically connected to the circuit board 12. In the embodiment shown in fig. 3, the interface 23 includes a power interface 231, a USB interface 233, a network cable interface 235, and the like. The power interface 231 is used to connect an external power source to supply power to the client front-end device 10 by using the external power source, and the USB interface 233 is used for data transmission between the client front-end device 10 and the external device. Of course, the USB interface 233 and the power interface 231 may be integrated to simplify the arrangement of the interface 23 of the client front end device 10. The network cable interface 235 may further include a wired network access terminal and a wired network output terminal. Customer premises equipment 10 may be connected to the network via a wired network access port and then to other devices via one or more wired network output ports. Of course, in some embodiments, the wired network output may be default, that is, after the client front-end device 10 accesses the network using the wired network input, the radio frequency system 13 is used to convert the wired network into a wireless network (e.g., WIFI) for an external device to access the network. Of course, both the wired network access terminal and the wired network output terminal can be omitted, and in this embodiment, the customer premises equipment 10 can access a cellular network (also called a mobile network) through the radio frequency system 13 and then convert into a WiFi signal for an external device to access the network.

Referring to fig. 2 and 3, the housing 11 may further be provided with a key 261 or the like, and the key 261 is used to control the operation state of the client front-end device 10. For example, the user may turn on the client front end device 10 or turn off the client front end device 10 by pressing the button 261. Of course, the housing 11 may be further provided with an indicator light or the like for prompting the operating state of the customer premises equipment 10. In some embodiments, the keys 261 and the plurality of interfaces 23 are disposed on the same side of the circuit board 12 and exposed on the same side of the housing 11, which facilitates the assembly of the keys 261 and the interfaces 23 with the circuit board 12, improves the appearance of the client front device 10, and improves the convenience of use. Of course, this arrangement may be replaced with other arrangements, for example, the interface 23 and the keys 261 may be exposed on different sides of the housing 11, respectively.

Further, referring to fig. 4, the main body of the customer premises equipment 10 includes a first heat sink 16 and a heat dissipation fan 17, the first heat sink 16 is made of a metal material (e.g., aluminum alloy) with good heat dissipation performance and is connected to the circuit board 12, and the heat dissipation fan 17 is connected to the housing 11 and is electrically connected to the circuit board 12. The first heat dissipation element 16 has a relatively large heat dissipation surface area, which is beneficial for dissipating heat generated by the circuit board 12 and the electronic components thereon into the air relatively quickly. In some embodiments, the first heat dissipating element 16 is made of an aluminum alloy, and referring to fig. 5, the first heat dissipating element 16 includes a first carrier plate 161 and a plurality of first heat dissipating fins 163 disposed on one side of the first carrier plate 161, the plurality of first heat dissipating fins 163 are disposed at intervals, and the first carrier plate 161 is attached to the circuit board 12. Referring to fig. 6, in some embodiments, the housing 11 is provided with heat dissipation holes 111 at both ends thereof, respectively, and the heat dissipation fan 17 is disposed near one end of the housing 11. The heat radiation holes 111 may be provided in an end surface of the housing 11, or may be provided in the circumferential direction of the housing 11 and located near an end of the housing 11, as shown in fig. 6. When the heat dissipation fan 17 is operated, external air is sucked from one end of the housing 11 and blown to the circuit board 12 and the position of the first heat dissipation member 16, and the air carrying heat flows out from the other end of the housing 11. Further, referring to fig. 5, the gap formed by two adjacent first heat dissipation fins 163 extends along the length direction of the housing 11, so that the airflow blown by the heat dissipation fan 17 can flow through the gap between two adjacent first heat dissipation fins 163, and further flow out from one end of the housing 11 far away from the heat dissipation fan 17. Of course, in other embodiments, the heat dissipation fan 17 may draw air from the side of the circuit board 12 and the first heat dissipation member 16, and the air carrying heat flows through the heat dissipation fan 17 and then flows out of the housing 11. The arrangement of the first heat dissipation element 16 and the heat dissipation fan 17 can improve the heat dissipation performance of the customer premises equipment 10. Further, in some embodiments, the first heat dissipation elements 16 include two first heat dissipation elements 16, and the two first heat dissipation elements 16 are disposed on opposite sides of the circuit board 12, so that the heat dissipation performance of the customer premises equipment 10 is further improved.

The mm-wave antenna rf module 1340 can provide a continuous bandwidth of more than 100M and a very large data throughput, so that the customer premises equipment 10 has a relatively high communication performance. Further, the sub-6G antenna rf module 1330 includes an rf transceiver, a plurality of rf front-end modules, and N antennas, where N is an integer greater than or equal to 2. The N antennas may include directional antennas and/or omni-directional antennas. The N antennas may transmit and receive radio frequency signals in a predetermined frequency band, for example, the N antennas may be NR directional antennas or NR omni-directional antennas, and are configured to transmit and receive 5G signals. A Directional antenna (Directional antenna) is an antenna that emits and receives electromagnetic waves in one or more specific directions with a strong intensity, and emits and receives electromagnetic waves in other directions with a null or minimum intensity. The omnidirectional antenna shows 360-degree uniform radiation on a horizontal directional diagram, has no directivity, shows a beam with a certain width on a vertical directional diagram, and generally, the smaller the lobe width is, the larger the gain is.

The plurality of antenna interfaces may be understood as analog switches, which may be disposed outside the rf circuit 242 or may be embedded in the rf circuit 242. The control unit for controlling the antenna interface may be an MIPI control unit and/or a GPIO control unit. When the radio frequency paths between the first antenna, the second antenna and the radio frequency transceiving unit 2422 need to be conducted, the MIPI control unit may output clock and data signals to the MIPI interface connected to the first antenna or/and the second antenna correspondingly, so as to control the conduction of the radio frequency paths between the first antenna or/and the second antenna and the radio frequency transceiving unit 2422. Correspondingly, the GPIO control unit may be configured to output the clock signal and the data signal to a GPIO interface connected to the first antenna or/and the second antenna, so as to control the rf path on which the first antenna or/and the second antenna is/are connected.

Specifically, the client front-end device 10 may control any transceiver antenna group to correspondingly acquire channel quality information in the network information when the transceiver antenna group is in the working state. The channel quality information may include at least one of a modulation order, a code rate, or a spectral efficiency. The Quality of the Channel Quality can be characterized by an index quantized into a Channel Quality Indicator (CQI). The channel quality information acquired by the client front-end device 10 may reflect the quality of the current channel. The embodiments of the present application take frequency efficiency acquisition as an example for explanation.

Illustratively, the client front-end device 10 may obtain the per-flow CQI value CQI through Sinr according to the CQI-Sinr mapping table, as shown in table 1_kAnd correspondingly acquiring the code rate R of each stream according to the CQI-code rate mapping table as shown in Table 2_kAnd then obtaining the corresponding spectral efficiency according to a spectral efficiency formula:

table 1 is a CQI-Sinr mapping table

CQI	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15
																Sinr	-6	-4	-2.75	-0.75	1.25	2.75	5.0	6.75	8.5	10.75	12.5	14.5	16.25	17.75	20

TABLE 2 CQI-Rate mapping Table

The modulation order determines the number of bits transmitted in 1 symbol. For example, Quadrature Phase Shift Keying (QPSK) corresponds to a Modulation order of 2, 16QAM (quadrature amplitude Modulation) has a Modulation order of 4, and 64QAM has a Modulation order of 6.

The code rate is the ratio between the number of information bits in the transport block and the total number of bits of the physical channel.

The spectrum efficiency represents information bits that can be carried by one Resource Element (RE).

It can be understood that, before the base station sends the downlink data, it is not clear how the condition of the data channel is, and in order to improve the reliability of data transmission, the quality of the channel can be measured by the client front-end device 10 and fed back to the network device. The communication protocol quantizes the channel quality to a sequence of 0-15 and defines CQI. Each CQI corresponds to a mapping relationship.

With the advent of the 5G era, the client front-end device 10 supports a 5G NR network (including NSA and SA schemes) while supporting a conventional 2/3/4G network. When the client front-end device 10 supports 5G communication, antenna shaping is generally implemented by using a 4x4MIMO technology, so that the downlink 4x4MIMO obtains the best data transmission performance. When the client premises equipment 10 supports 4 × 4MIMO, the processor 22 may be configured to configure the rf circuit 242 to select four antennas from the N first antennas and the two second antennas to form a transceiving antenna group for transceiving antenna signals. The client front-end device 10 adopts a 4-antenna (four antennas are selected from multiple antennas) scheme, that is, four transmit-receive antennas on a radio frequency path are provided, which can implement 1T4R (one transmit four receiver, that is, one path is provided for transmission and four paths are provided for reception) and 2T4R (two transmit four receiver, that is, two paths are provided for transmission and four paths are provided for reception) in NSA and SA scenarios.

In one embodiment, the processor 22 may be configured to detect whether both of the two second antennas are conductively connected to the peripheral antenna interface 237. For example, the second antenna B1 may be connected to the peripheral antenna interface M1, and the second antenna B2 may be connected to the peripheral antenna interface M2. The antenna interfaces M1, M2 may be MIPI and/or general purpose input/output GPIO interfaces for the mobile industry processor 22. For example, when the peripheral antenna interface M1 is an MIPI1 interface and the peripheral antenna interface M2 is an MIPI2 interface, the processor 22 may correspondingly obtain clock and data signals input to the MIPI1 interface and the MIPI2 interface, and further may detect whether the peripheral antenna interface M1 turns on a radio frequency path between the second antenna B1 and the radio frequency transceiving unit 2422, and may detect whether the peripheral antenna interface M2 turns on a radio frequency path between the second antenna B2 and the radio frequency transceiving unit 2422.

When the MIPI1 interface turns on the rf path between the second antenna B1 and the rf transceiver unit 2422 and the MIPI2 interface turns on the rf path between the second antenna B2 and the rf transceiver unit 2422, it indicates that the rf circuit is currently controlling the two second antennas B1 and B2 to receive antenna signals.

In one embodiment, two of the radiation plane of the antenna group 1, the radiation plane of the antenna group 3, the radiation plane of the antenna group 2, and the radiation plane of the antenna group 4 that are adjacent in sequence form an acute angle or a right angle. The radiation surface is understood to be the plane on which the outward side of the radiation patch of the antenna is located, from which the antenna receives electromagnetic wave signals.

In the following examples, N ═ 8 is exemplified.

In one embodiment, the processor 22 may be configured to configure two first antennas from the eight first antennas as a first antenna set, where the two antennas in the first antenna set have two adjacently disposed radiating surfaces. Illustratively, the first set of antennas may include (a1, A3), (a2, A3), (a2, a4), (a4, a1), and so on. Any one of the first antenna sets and the two second antennas may be combined to form a first transceiving antenna group, so that the first transceiving antenna group includes the two first antennas and the two second antennas.

When the peripheral antenna interface conducts a radio frequency path between the two second antennas and the radio frequency circuit, the processor may configure the radio frequency circuit 242 to control the MIPI control unit and/or the GPIO control unit to sequentially control the radio frequency path between the two first antennas in each first antenna set and the radio frequency circuit, so that each first transceiving antenna group is in a working state, and further, network information of each first transceiving antenna group receiving antenna signal is correspondingly measured. The processor 22 may obtain network information corresponding to each first transceiving antenna group from the rf circuit 242, and may further determine a target transceiving antenna group. The first antenna set in the target transceiver antenna group may be referred to as a target antenna set. Processor 22 configures radio frequency circuitry 242 to control the target set of transmit and receive antennas to transmit and receive antenna signals.

Illustratively, a reference signal parameter is screened from at least one signal parameter of the network information, and a reference signal parameter having a maximum value is screened from the plurality of network information, and the network information of the maximum value reference signal parameter is taken as the target network information. In the embodiment of the present application, the description may be made by taking the network information as the reference signal received power as an example. That is, the processor may be configured to obtain multiple reference signal received powers of multiple transceiver antenna groups, obtain a maximum value of the multiple reference signal received powers, and use the maximum value as target network information, where a transceiver antenna group corresponding to the target network information is a target transceiver antenna group.

In one embodiment, the processor 22 may be further configured to configure two first antennas from the eight first antennas as a second antenna set, where the two antennas in the second antenna set have the same radiation plane. For example, the second antenna set may include (a1, a6), (a2, a5, (A3, a7), (a4, A8), where any one of the second antenna sets may be combined with two second antennas to form a second transceiving antenna group, such that the second transceiving antenna group includes two first antennas and two second antennas.

When the peripheral antenna interface simultaneously conducts radio frequency paths between the two second antennas and the radio frequency circuit, the processor may configure the radio frequency circuit 242 to control the MIPI control unit and/or the GPIO control unit to sequentially control the radio frequency paths between the two first antennas in each second antenna set and the radio frequency circuit, so that each second transceiving antenna group is in a working state, and further, network information of each second transceiving antenna group receiving antenna signal is correspondingly measured. The processor 22 may obtain network information corresponding to each second transceiving antenna group from the rf circuit 242, and may further determine a target transceiving antenna group. The second antenna set of the target transceiver antenna set may be referred to as a target antenna set. Processor 22 configures radio frequency circuitry 242 to control the target set of transmit and receive antennas to transmit and receive antenna signals.

In one embodiment, the processor 22 may configure a plurality of first transceiver antenna groups and a plurality of second transceiver antenna groups. The processor 22 may further configure the radio frequency circuit 242 to implement switching control of the plurality of transmit-receive antenna groups according to an alternating switching path of the first transmit-receive antenna group → the second transmit-receive antenna group → the first transmit-receive antenna group → … → the second transmit-receive antenna group. Specifically, two antennas in the first transceiving antenna group and the second transceiving antenna group which are switched adjacently have the same identification information.

The radio frequency circuit 242 may correspondingly and alternately measure network information of the antenna signals when the first and second transceiver antenna groups are in an operating state in a process of controlling the switching of the plurality of transceiver antenna groups. The processor 22 may determine the target transceiver antenna group according to the network information corresponding to the plurality of first transceiver antenna groups and the plurality of second transceiver antenna groups measured alternately by the radio frequency circuit 242.

For example, the network information with the maximum value may be screened from the plurality of network information, and the transceiver antenna group corresponding to the network information with the maximum value may be used as the target transceiver antenna group. The target transceiver antenna group can be a first transceiver antenna group or a second transceiver antenna group.

The client front-end device 10 can intelligently determine the target transceiving antenna group (the optimal four antennas are used as transmitting/receiving antennas) no matter where the base station is, the client front-end device 10 can dynamically determine the optimal antenna transmitting/receiving direction for communicating with the base station, and directionally and cater to the uplink and downlink incoming wave directions of the base station to complete the transceiving of 5G signals, so that the overall signal coverage is improved, the throughput effect is improved, the advantages of high speed and high communication capacity of 4x4MIMO are ensured, the antenna gain is improved, the coverage is increased, the energy consumption of other antennas with weak received signals during working is avoided, and the system heat dissipation is facilitated.

In one embodiment, when the processor 22 determines the target transceiver antenna group, it may be further configured to update the target transceiver antenna group as follows: and when the network information measured by the two second antennas does not accord with a preset condition, configuring the peripheral antenna interface to disconnect the radio frequency paths between the two second antennas and the radio frequency circuit, and controlling the radio frequency circuit to select four antennas from the eight first antennas so as to update the target transceiving antenna group.

The preset condition may be a minimum threshold for supporting 5G communication or a minimum threshold for accessing to the 5G network system. For example, the signal quality in the network information is less than a preset signal quality (e.g., reference signal received power RSRP is less than 10 dB). When the network information measured by the two second antennas is not enough to support 5G communication, the two second antennas and the radio frequency circuit may be disconnected, and a fourth first antenna may be selected from the eight first antennas to update the target transceiving antenna group.

In one embodiment, the processor 22 is further configured to update the target set of transceiver antennas as follows. Processor 22 may configure rf circuit 242 to control two first antennas of the target antenna set to continue receiving the antenna signals, and configure a plurality of third antenna sets with two first antennas from the remaining six first antennas. That is, the rf circuit 242 may still turn on the rf path where the two first antennas in the target antenna set are located, so that the two first antennas in the target antenna set continue to receive the antenna signal.

Wherein the radiation surface of each of the first antennas in the third antenna set and the target antenna set faces at least two directions.

Specifically, the radiation surfaces of four first antennas in the third antenna set and the target antenna set face two adjacent directions, and two radiation surfaces face the same antenna. Illustratively, if a first antenna in the target set of antennas includes an antenna (a1, a7), its corresponding third set of antennas includes an antenna (a6, A3).

Optionally, four first antennas in the third antenna set and the target antenna set have three sequentially adjacent radiation surfaces facing different directions. The three radiation surfaces adjacent in sequence comprise a first radiation surface, a second radiation surface and a third radiation surface, wherein the radiation surface of one first antenna is the first radiation surface, the radiation surfaces of the two first antennas are the second radiation surface, and the radiation surface of one first antenna is the third radiation surface. Illustratively, if a first antenna in the target antenna set includes an antenna (a1, a7), its corresponding third antenna set includes antennas (a6, a4), (a6, A8), (A3, a2), (A3, a 5).

The processor 22 may configure the rf circuit 242 to control the rf paths of the four first antennas in the target antenna set and any one of the third antenna sets to be turned on, so that the four first antennas in the target antenna set and any one of the third antenna sets receive the antenna signal at the same time, and correspondingly measure a plurality of network information of the antenna signals received by the four first antennas in different combinations. Processor 22 may obtain a plurality of network information from rf circuit 242 and may determine a new target set of transmit and receive antennas based on the plurality of network information. The processor 22 may configure the rf circuit 242 to control the new target antenna group to transmit and receive antenna signals to update the original target antenna group.

In one embodiment, when the network information measured by the two second antennas is not enough to support 5G communication, the two second antennas may be disconnected from the radio frequency circuit, and four first antennas may be selected from the eight first antennas to update the target transceiver antenna group.

The processor is further configured to configure a plurality of third transmit and receive antenna groups from the eight antennas of the first antenna. The third transceiving antenna group comprises four antennas, and the four antennas are provided with three radiation surfaces which are adjacent in sequence and face different directions. As shown in fig. 25, the four antennas in the third transceiving antenna group are distributed on three sequentially adjacent surfaces, and a group of antennas is disposed on the middle surface of the three sequentially adjacent surfaces. The three radiation surfaces adjacent in sequence comprise a first radiation surface, a second radiation surface and a third radiation surface, wherein the radiation surface of one antenna in the four antennas is the first radiation surface, the radiation surfaces of the two antennas are the second radiation surface, and the radiation surface of one antenna is the third radiation surface. For example, the third transceiving antenna group may be a third transceiving antenna group (a1, A6, A8, A3), (a4, A8, a2, A6), (a2, a5, A3, A8), (A3, a4, a2, A6), and so on.

Processor 22 may configure radio frequency circuit 242 to control the MIPI control unit and/or the GPIO control unit to control each third transceiver-antenna group to search for antenna signals and to measure network information measured by each third transceiver-antenna group. Specifically, the rf circuit 242 may sequentially control and conduct the rf path between each transceiver antenna group and the rf transceiving unit 2422, so that each third transceiver antenna group is in a working state, and further, network information of each third transceiver antenna group receiving antenna signal is correspondingly measured.

The processor 22 may obtain network information corresponding to each third transceiving antenna group from the rf circuit 242, and may further determine a target third transceiving antenna group. Illustratively, a reference signal parameter is screened from at least one signal parameter of the network information, and a reference signal parameter having a maximum value is screened from the plurality of network information, and the network information of the maximum value reference signal parameter is taken as the target network information. The processor 22 configures the radio frequency circuitry 242 to control the target third transmit/receive antenna group to transmit/receive antenna signals to update the target transmit/receive antenna group.

In one embodiment, each of the first antennas carries identification information indicating a radiation surface of each of the second antennas. Since the antennas a1, a6 have a radiation surface 1, the antennas a2, a5 have a radiation surface 3, the antennas A3, a7 have a radiation surface 4, and the antennas a4, A8 have a radiation surface 4. Illustratively, radiating surfaces 1, 2, 3, 4 may be identified by 001, 002, 003, 004, respectively. It should be noted that the identification information of the radiation surface may also be represented by at least one of numbers, letters and symbols, and the identification information of the radiation surface is not further limited in this application.

The processor is further configured to update the target set of transceiver antennas as follows: acquiring the polarization direction and the identification information of each antenna in the target transceiving antenna group; determining two first antennas to be switched in the target transceiving antenna group according to the identification information; and configuring the radio frequency circuit to update the target transceiving antenna according to the two first antennas to be switched.

When the processor 22 obtains the target third transceiver-antenna group, the processor 22 is further configured to obtain the polarization direction and identification information of each branch antenna in the target third transceiver-antenna group. And determining two first antennas to be switched in the target third transceiving antenna group according to the identification information. For example, if the target third transceiving antenna group is the third transceiving antenna group (a4, A6, a1, a7), it may be determined that the identification information of the two first antennas to be switched in the target third transceiving antenna group is 004 and 002 according to the identification information 004, 001, and 002, respectively, and then the first antenna a4 of the target third transceiving antenna group may be switched to the third antenna A8 having the same identification information as the first antenna a4 and having the opposite polarization direction, and the second antenna a7 may be switched to the fourth antenna A3 having the same identification information as the second antenna a7 and having the opposite polarization direction, so as to form a new third transceiving antenna group (A8, A6, a1, A3). The radio frequency circuit 242 may switch the target third transceiving antenna group to the transceiving antenna group (A8, a6, a1, A3) and measure network information of the antenna signal received by the third transceiving antenna group (A8, a6, a1, A3) correspondingly. The processor 22 may correspondingly obtain two network information corresponding to the target third transceiving antenna group (a4, a6, a1, a7) and the third transceiving antenna group (A8, a6, a1, A3), compare the two network information, and use the third transceiving antenna group corresponding to the network information with a larger size as a new target third transceiving antenna group, so as to update the original target third transceiving antenna group, and further configure the radio frequency circuit 242 to control the new target third transceiving antenna group to be in a working state to transceive an antenna signal. In this embodiment, the target third transceiving antenna group may be calibrated and updated, so that the antenna gain may be further improved.

In one embodiment, the processor is further configured to update the target set of transceiver antennas as follows. Specifically, the processor 22 may be configured to select four antennas from eight antennas based on a permutation and combination manner to form a plurality of fourth transceiving antenna groups. As shown in fig. 26, the four antennas of the fourth transceiving antenna group have two adjacent radiation surfaces facing different directions. It will also be appreciated that the fourth transmit and receive antenna group comprises two groups of antennas, wherein the two groups of antennas are distributed on two adjacent planes. For example, the four fourth transceiving antenna groups may be referred to as fourth transceiving antenna groups (a1, A6, A3, a7), (A3, a7, a2, a5), (a2, a5, a4, A8), (a4, A8, a1, A6), respectively.

Based on the configured plurality of fourth transceiving antenna groups, the processor 22 may control the radio frequency circuit 242 to turn on the radio frequency paths of the plurality of fourth transceiving antenna groups, so that the radio frequency circuit 242 correspondingly measures the network information of the antenna signals received by the plurality of fourth transceiving antenna groups. The processor 22 may determine a target fourth transceiver antenna group according to a plurality of network information measured by the radio frequency circuit 242, and further may configure the radio frequency circuit 242 to turn on a radio frequency path where the target fourth transceiver antenna group is controlled to enable the target fourth transceiver antenna group to be in a working state, so as to receive and transmit antenna signals, and further implement update processing on the target transceiver antenna group.

In one embodiment, the client front-end device 10 may determine the target third transceiver antenna group in another manner. Specifically, the processor 22 controls the radio frequency circuit 242 to implement the switching control of the multiple transceiver antenna groups according to the alternating switching path of the third transceiver antenna group → the fourth transceiver antenna group → the third transceiver antenna group → … → the fourth transceiver antenna group. Specifically, two antennas in the third transceiving antenna group and the fourth transceiving antenna group which are switched adjacently have the same identification information.

It should be noted that the radio frequency circuit 242 implements a plurality of alternate switching paths for controlling switching of the plurality of transceiver antenna groups.

The radio frequency circuit 242 may be configured to, in a process of controlling the switching of the multiple transceiver antenna groups, correspondingly and alternately measure network information of the antenna signals when the multiple third transceiver antenna groups and the multiple fourth transceiver antenna groups are in an operating state. The processor 22 may determine a target third transceiving antenna group according to the network information corresponding to the plurality of third transceiving antenna groups and the plurality of fourth transceiving antenna groups alternately measured by the radio frequency circuit 242.

Further, the processor 22 may obtain the identification information of each branch antenna radiation surface in the third transceiving antenna group currently in the working state. For example, as shown in fig. 27, if the current third transceiving antenna group is the third transceiving antenna group (a1, A6, A3, A4), a corresponding alternate switching path may be, the third transceiving antenna group (a1, A6, A3, A4) → the fourth transceiving antenna group (a1, A6, A3, A7) → the third transceiving antenna group (a2, a1, A3, A7) → the fourth transceiving antenna group (a2, A5, A3, A7) → the third transceiving antenna group (a2, A5, A3, A4) → the fourth transceiving antenna group (a2, A5, A4, A8) → the third transceiving antenna group (A8, A8) → the fourth transceiving antenna group (a 8672, A8).

The processor 22 may be configured to acquire network information measured based on the third transceiving antenna group (a1, a6, A3, a4) and the fourth transceiving antenna group (a1, a6, A3, a7) to select a switching path of the next transceiving antenna group. If the network information measured by the third transceiving antenna group (a1, A6, A3, a4) is greater than the network information measured by the fourth transceiving antenna group (a1, A6, A3, a7), the fourth transceiving antenna group (a1, A6, A3, a7) switches to the third transceiving antenna group (a1, A6, a4, A8). Otherwise, the fourth transceiving antenna group ((a1, a6, A3, a7) is switched to the third transceiving antenna group (a2, a1, A3, a 7).

In this embodiment, the client premises equipment may switch from the third transceiving antenna group to the fourth transceiving antenna group based on the alternate switching path, and in the switching process, a next switching transceiving antenna group may be preferentially selected from a plurality of switching paths of the alternate switching path, so that the efficiency of determining the target third transceiving antenna group may be improved.

In one embodiment, the processor is further configured to: configuring a plurality of fifth transceiving antenna groups from eight first antennas; the fifth transceiving antenna group comprises four first antennas, and the radiation surfaces of the four first antennas of the fifth transceiving antenna group face in different directions.

As shown in fig. 28, one antenna can be selected from each of the four antenna groups to form the fifth transceiver antenna group, and the radiation surfaces of the four antennas of the fifth transceiver antenna group face four different directions.

The processor 22 may be further configured to: and screening out a reference access antenna group according to at least one fifth transceiving antenna group. When the client front-end device is powered on, the distribution conditions of base stations and NR cells around the client front-end device are not known, and in order to enable the client front-end device to access the 5G network system with the maximum probability, any group of fifth transceiver antenna groups may be used as a reference access antenna group to attempt access. For example, the reference access antenna group may be a transceiving antenna group (A6, A8, a2, A3), a transceiving antenna group (A6, a4, a2, a7), a transceiving antenna group (a1, A8, a5, A3) and a transceiving antenna group (a1, a4, a5, a 7). It should be noted that, due to the band limitation of n41, the last scheme (a1, a4, a5, a7) does not serve as a reference access antenna group.

The fifth transceiver antenna group (a6, A8, a2, A3) is taken as an example of the reference access transceiver antenna group. The processor 22 may be further configured to control the radio frequency circuit 242 to perform a switching operation from the reference access antenna group to each third transceiver antenna group according to a first preset switching policy. The first preset switching strategy comprises that the reference access antenna group and the third transceiving antenna group are alternately switched, and the reference access antenna group is used as a starting transceiving antenna group.

For example, when the fifth transceiving antenna group (a6, A8, a2, A3) is successfully accessed, as shown in fig. 29, the specific traverse switching path according to the first preset switching policy is as follows: the fifth transceiving antenna group (A6, A8, a2, A3) → the third transceiving antenna group (a1, A6, A8, A3) → the fifth transceiving antenna group (A6, A8, a2, A3) → the third transceiving antenna group (A3, A7, a2, A6) → the fifth transceiving antenna group (A6, A8, a2, A3) → the third transceiving antenna group (a2, A5, A8, A3) → the fifth transceiving antenna group (A6, A8, a2, A3) → the third transceiving antenna group (A4, A8, a2, A6).

Further, the processor 22 may obtain identification information of the reference access antenna group, and determine, according to the identification information, a plurality of third transceiving antenna groups that need to be switched in a traversal manner in the first preset switching policy. And the identification information of three antennas in the plurality of third transceiving antenna groups needing traversing switching is the same as the identification information of three antennas in the reference access antenna group. Optionally, the plurality of third transceiver antenna groups that need to be switched in a traversing manner in the first preset switching policy may also be all the third transceiver antenna groups.

The radio frequency circuit 242 may correspondingly measure network information of antenna signals received by each transceiver antenna group when the plurality of transceiver antenna groups are controlled to be in the working state in sequence according to the first preset switching policy, and the processor 22 may be further configured to determine a target third transceiver antenna group according to the network information measured by the radio frequency circuit 242 and corresponding to the plurality of third transceiver antenna groups.

In this embodiment, because the antenna signal radiated by the NR cell has a very strong directivity, the client front apparatus 10 may access any fifth transceiver antenna group as a reference to the transceiver antenna group to the 5G network system, and when the two groups of third transceiver antenna groups are switched, both the fifth transceiver antenna groups will be connected, so that a network drop condition during the switching process can be avoided, and the stability of accessing the 5G network system is ensured.

In one embodiment, the processor 22 may be configured to determine a plurality of said fourth transceiver-antenna groups from said target third transceiver-antenna group. Specifically, the processor 22 may configure the radio frequency circuit 242 to obtain identification information of each branch antenna in the target third transceiving antenna group; screening out a plurality of fourth transceiving antenna groups for updating the target third transceiving antenna group according to the identification information; and configuring the radio frequency circuit to update the target third transceiving antenna group according to the network information corresponding to the plurality of fourth transceiving antenna groups.

For example, when the target third transceiving antenna group is the third transceiving antenna group (a1, a6, A3, a4), it may correspond to acquiring the identification information 001, 001, 003, 004 of each branch antenna. Further, the processor 22 may be configured to screen out multiple sets of fourth transceiving antenna groups (a4, A8, a6, a1, A3 or a7) and (a6, a1, A3, a7) for updating the target third transceiving antenna group according to the identification information 001, wherein two antennas in the screened out fourth transceiving antenna groups must have the radiation plane 1 with the identification information 001. Based on the network information measured by the plurality of fourth transceiving antenna groups correspondingly measured by the radio frequency circuit 242, the processor 220 may obtain the network information having the maximum value based on the network information of the antenna signal measured correspondingly by each fourth transceiving antenna group, compare the network information having the maximum value with the network information corresponding to the target third transceiving antenna group, if the network information having the maximum value is larger, use the fourth transceiving antenna group having the network information having the maximum value as a new target third transceiving antenna group, and further control the radio frequency circuit 242 to conduct a radio frequency path where the new target third transceiving antenna group is located, so as to enable the target third transceiving antenna group to transceive the antenna signal. Otherwise, the original target third transceiving antenna group is maintained unchanged.

In one embodiment, the processor 22 may be further configured to: and screening out a reference access antenna group according to at least one fifth transceiving antenna group. When the client front-end device is powered on, the distribution conditions of base stations and NR cells around the client front-end device are not known, and in order to enable the client front-end device to access the 5G network system with the maximum probability, any group of fifth transceiver antenna groups may be used as a reference access antenna group to attempt access.

The fifth transceiver antenna group (a6, A8, a2, A3) is taken as an example of the reference access transceiver antenna group. The processor 22 may be further configured to control the radio frequency circuit 242 to perform the switching operation from the reference access antenna group to each fourth transceiving antenna group according to the second preset switching policy. The second preset switching strategy comprises that the reference access antenna group and the fourth transceiving antenna group are alternately switched, and the reference access antenna group is used as a starting transceiving antenna group.

For example, the fifth transceiver antenna group (a6, A8, a2, A3) is taken as a reference access antenna group for explanation. When the fifth transceiving antenna group (a6, A8, a2, A3) is successfully accessed, as shown in fig. 30, the specific switching traversal path according to the second preset switching policy is as follows: the fifth transceiving antenna group (A6, A8, a2, A3) → the fourth transceiving antenna group (a1, A6, A8, A3) → the fifth transceiving antenna group (A6, A8, a2, A3) → the fourth transceiving antenna group (A6, A8, A4, a2) → the fifth transceiving antenna group (A6, A8, a2, A3) → the fourth transceiving antenna group (A8, a2, A5, A3) → the fifth transceiving antenna group (A6, A8, a2, A3) → the fourth transceiving antenna group (A6, a2, A3, A7).

In one embodiment, the processor 22 is further configured to: and constructing a third preset switching strategy according to the identification information of each branch antenna in the fifth transceiving antenna group, the fourth transceiving antenna group and the fifth transceiving antenna group. The third preset switching strategy at least comprises switching according to the fifth transceiving antenna group, the fourth transceiving antenna group and the fifth transceiving antenna group in sequence.

The processor 22 is further configured to control the radio frequency circuit 242 to control the plurality of transceiver antenna groups to be in an operating state in sequence according to a third preset switching policy, and correspondingly measure network information of the antenna signals received by each transceiver antenna group. The processor 22 may determine a target fifth transceiving antenna group based on the measured network information of the fifth transceiving antenna group, the fourth transceiving antenna group, and the fifth transceiving antenna group corresponding to the radio frequency circuit 242. The target fifth transceiving antenna group is a fifth transceiving antenna group, a fourth transceiving antenna group or a fifth transceiving antenna group, and the configurable radio frequency circuit 242 controls the target fifth transceiving antenna group to transceive the antenna signal.

In this embodiment, the client front-end device may perform switching between the transceiver antenna groups based on a third preset switching policy, so as to improve the efficiency of determining the target fifth transceiver antenna group.

In one embodiment, the client premises equipment 10 may operate in a non-standalone networking mode as well as in a standalone networking mode. The third Generation Partnership Project (3rd Generation Partnership Project, 3GPP) defines two schemes for 5G New air interface (New Radio, NR) networking, which are independent networking (SA) and Non-independent Networking (NSA). When the client front-end device 10 needs to perform 5G communication, the client front-end device 10 may access a cell with a capability of supporting non-independent networking or independent networking, and access an air interface of the NR according to different networking modes, so as to enjoy 5G services.

When the client front-end 10 is operating in the non-standalone networking mode, the processor 22 is further configured to: receiving a measurement instruction sent by a base station based on a first network system; the measurement instruction includes at least time information configured by the base station for instructing the client front-end device 10 to measure the antenna signal supported by the second network system; the first network system is a 4G network system, and the second network system is a 5G network system; and controlling a driving mechanism to drive the millimeter wave antenna module to rotate based on an interval stepping strategy according to the measurement instruction.

Specifically, the processor 22 may be configured to actively initiate a first network system network entry procedure and reside in the first network system. When successfully residing in the first network system, the client front-end device 10 may receive a measurement instruction transmitted from the base station through the first network system. The measurement instruction at least includes time information configured by the base station, a network access threshold value of the client front-end device 10 residing in the second network system, and the like. Wherein the time information is used to instruct the client front-end device 10 to measure the time of the second network system. For example, the time information may be periodic information or aperiodic information for the client front-end device 10 to perform the second network system measurement. The period information is an interval between the start time of the first measurement and the start time of the second measurement, or an interval between the end time of the first measurement and the start time of the second measurement, when the client front-end device 10 performs two adjacent measurements; or the interval between the end time of the first measurement and the end time of the second measurement.

The first network system and the second network system may correspond to respective frequency band ranges. Exemplarily, the first network system is a 4G network, and the corresponding network system is an LTE system; the second network system is a 5G network, and the corresponding network system is a 5G NR system.

The measurement instruction is configured by the base station, and the base station can set different time information according to the network deployment density of the NR system. Illustratively, the time information may be 1 second, 5 seconds, 10 seconds, and the like. For example, when the base station determines that the NR system has a good coverage to the area where the client front-end device 10 is located when the base station determines that the NR cells around the LTE cell where the client front-end device 10 is located are densely wired, the base station may control the client front-end device 10 to measure longer time information of the second network system, so as to reduce the power consumption of the client front-end device 10 better; when the base station determines that the NR cells around the LTE cell where the client front-end device 10 is located are sparsely networked, the base station may control the client front-end device 10 to measure the second network system in a shorter time, so as to ensure that the client front-end device 10 can detect whether the second network system is covered in time.

Alternatively, when the network in which the client front end device 10 resides is a first network system (4G network) and the second network system thereof may be a 5G network, the first network system (LTE system) supports the NSA function, that is, supports joint networking with the second network system (NR system).

Specifically, the processor 22 is configured to control the plurality of first transceiver antenna groups to be in an operating state according to the measurement instruction so as to correspond to the network information of the measurement antenna signal. The client front-end device 10 may periodically measure the network information of the antenna signal according to the measurement instruction configured by the base station, so as to avoid the disadvantage of increasing the power consumption of the client front-end device 10 caused by the real-time and continuous measurement of the network information of the antenna signal.
