Background

With the continuous development of communication technology, base station products are more and more abundant and have various characteristics, wherein a distributed base station is a base station structure with the advantages of low cost, strong environmental adaptability, convenient engineering construction and the like, and particularly in a 3G mobile network, the distributed base station is widely applied.

The distributed Base station structure divides the traditional macro Base station equipment into a Base Band Unit (BBU) and a Radio Remote Unit (RRU) according to functions, and the BBU and the RRU are connected through optical fibers. When the network is deployed, the BBU, the core network and the wireless network control equipment are centralized in a machine room and connected with the RRU deployed on the planning station through optical fibers to complete network coverage.

However, the current distributed base station structure has the following problems:

1. currently, international mainstream 3G systems are various, such as CDMA2000, WCDMA, TD-CDMA, and the like, and each system has different stage versions, most distributed base station systems only support single-system signals, and mobile operators usually need to combine communication devices supporting signals of different systems to meet signal coverage, so that not only is the cost high, the device size large, but also the implementation is relatively complex;

2. in a distributed base station system, a BBU (base band unit) and an RRU (remote radio unit) can be connected only through optical fibers and are limited by difficult maintenance of an optical fiber network and high manufacturing cost of optical fiber resources;

3. the distributed base station system usually adopts the RRH (Radio Remote Head, Radio Remote front end) + electric tuning antenna technology to realize outdoor coverage, and 1-3 dB feeder loss exists between the RRH and the electric tuning antenna, so that the signal receiving sensitivity is reduced;

4. the distributed base station system adopts mechanical downtilt and electrical downtilt to realize the beam downtilt function, wherein the mechanical downtilt is a downtilt angle which is fixedly adjusted during engineering installation, and once the downtilt angle is adjusted, great workload is required for re-adjustment; the electric downtilt is realized by adjusting the phase of a transmission line in an antenna through a phase shifter, but the phase shifter has large volume, heavy weight and limited adjustment precision, and the phase can be changed after long-time work, and only the vertical beam downtilt function can be realized, so that the mechanical downtilt and the electric downtilt have certain limitation on realizing the beam downtilt function.

Specifically, the predetermined multiple systems may be set according to actual needs, and may include: GSM, WCDMA, CDMA, TD-SCDMAA, DCS, TD-SCDMAF and the like.

The transceiver device provided by the embodiment has the function of supporting multiple systems, and the structure of the device covers various systems, and simultaneously solves the problems of large volume and complex implementation of equipment caused by combining equipment supporting various different systems in the prior art.

Preferably, as shown in fig. 1(2), the transceiver apparatus provided in this embodiment further includes: a baseband processing unit 12, configured to receive and process an uplink baseband signal from the multi-system processing unit 11 in an uplink; in the downlink, a downlink baseband signal of any one of the predetermined multiple standards is generated, and the generated downlink baseband signal is sent to the multi-standard processing unit 11.

Specifically, when the transceiver device includes the baseband processing unit 12, the transceiver device itself has a baseband processing function, and can perform processing functions of layers such as a physical layer and a communication interface protocol on baseband signals of different systems without being connected to an external base station processing device.

In specific implementation, a network interface can be adopted to transmit baseband signals between the baseband processing unit 12 and the multi-system processing unit 11 based on an IP protocol, and compared with a technology of only supporting optical fiber to transmit baseband signals, the network interface based on the IP protocol can effectively utilize a network transmission mode with low manufacturing cost and convenient maintenance, and avoid the problems of high cost of optical fiber resources, inconvenient maintenance and the like caused by only supporting optical fiber transmission.

Preferably, as shown in fig. 1(3), the transceiver apparatus provided in this embodiment further includes: an external interface 13, configured to receive an uplink baseband signal from the multi-system processing unit 11 in an uplink, and send the uplink baseband signal to a base station processing apparatus; in the downlink, a downlink baseband signal of any one of the predetermined multiple systems is received from the base station processing apparatus and sent to the multi-system processing unit 11.

Specifically, when the transceiver device does not have the baseband processing function, the transceiver device can be connected with an external base station processing device having the baseband processing function by using the external interface 13, so as to achieve the purpose of sending the uplink baseband signal to the base station processing device for corresponding processing and receiving the downlink baseband signal from the base station processing device; the external interface 13 may be an optical fiber interface, and supports the function of transmitting baseband signals by using an optical fiber network.

Preferably, as shown in fig. 1(4), the multi-system processing unit 11 specifically includes: a multi-system amplification module 111, a multi-system radio frequency processing module 112 and a protocol data processing module 113; wherein,

a multi-system amplifying module 111, configured to receive, in an uplink, an uplink radio frequency signal in any one of the multiple predetermined systems, and send the uplink radio frequency signal to the multi-system radio frequency processing module 112; in the downlink, a downlink radio frequency signal is received from the multi-system radio frequency processing module 112, and the downlink radio frequency signal is sent out;

Specifically, the multi-system amplification module 111 has functions of identifying radio frequency signals of different system types, and performing corresponding filtering processing on the radio frequency signals of different system types;

the multi-system rf processing module 112 is configured to perform a function of mutual conversion between an rf signal and a digital signal, specifically, convert an uplink rf signal into an uplink digital signal by using an analog-to-digital conversion process, and convert a downlink digital signal into a downlink rf signal by using a digital-to-analog conversion process;

the protocol data processing module 113 is configured to complete conversion processing of a Digital signal and a baseband signal, and specifically perform DDC (Digital Down Converter), uplink Digital filtering, framing and other processing on an uplink Digital signal to obtain an uplink baseband signal, and perform de-framing, downlink Digital filtering, DUC (Digital Up Converter), Digital peak clipping and other processing on a downlink baseband signal to obtain a downlink Digital signal;

it should be noted that, because the radio frequency signals, the digital signals, and the baseband signals corresponding to different systems are different, when the multi-system amplifying module 111, the multi-system radio frequency processing module 112, and the protocol data processing module 113 process the radio frequency signals, the digital signals, and the baseband signals of different systems, different specific processing modes should also be adopted, for example: the multi-system amplification module 111 has different filter levels, filter suppression and the like configured for different systems; the multi-system radio frequency processing module 112 has different radio frequency filters for local oscillators configured in different systems; the protocol data processing module 113 has different configurations for DUC, DDC, digital peak clipping functions (including coefficients for peak clipping and number of steps for peak clipping), and the like.

Preferably, as shown in fig. 1(5), the multi-system amplification module 111 specifically includes: an antenna interface 1111, a standard selector 1112, and a plurality of standard circuits 1113; the plurality of standard circuits 1113 correspond to the predetermined plurality of standards one by one; wherein,

a standard selector 1112, configured to receive, in an uplink, an uplink radio frequency signal in any one of the predetermined multiple standards through the antenna interface 1111, and send the uplink radio frequency signal to a standard circuit 1113 corresponding to the standard of the uplink radio frequency signal; in downlink, a downlink radio frequency signal received from any standard circuit 1113 is sent out through the antenna interface 1111;

Specifically, in order to support processing of signals of multiple systems, the multi-system amplification module 111 needs to include multiple system circuits 1113, where each system circuit 1113 is dedicated to processing a signal of one system, for example, when the multiple predetermined systems are GSM, WCDMA, and CDMA, respectively, the multi-system amplification module 111 should have three system circuits 1113 for processing GSM signals, WCDMA signals, and CDMA signals, respectively; in addition, the multi-standard amplification module 111 employs the standard selector 1112 to send the signal to the corresponding standard circuit 1113 for processing according to the standard type of the signal, and in specific implementation, the standard selector 1112 is controlled by a software program, can automatically determine the standard type of the signal, and accurately send the signal to the corresponding standard circuit 1113 for processing.

In addition, it may also be set through a software program that the format selector 1112 is only used for processing a certain set format signal within a period of time, and when the format selector 1112 receives the set format signal, it will send it to the corresponding format circuit 1113 for processing, and when the format selector 1112 receives signals of other formats, it will not process. That is to say, the transceiver apparatus provided in this embodiment may, in addition to simultaneously supporting multi-system signal processing, enable the transceiver apparatus to process only single-system signals for a period of time by this arrangement.

Preferably, as shown in fig. 1(6), the standard circuit 1113 specifically includes: an uplink filter M1, a downlink filter M2, a receiver M3 and a transmitter M4; wherein,

a transmitter M4, configured to send, in a downlink, the downlink radio frequency signal received from the multi-system radio frequency processing module 112 to the downlink filter M2.

Specifically, since different standards have different uplink working frequency bands and downlink working frequency bands, in order to implement the function of the standard circuit 1113 in processing radio frequency signals of corresponding standards, a special uplink filter M1 should be designed for the uplink working frequency band of the standard, and a special downlink filter M2 should be designed for the downlink working frequency band of the standard, so as to achieve the purpose of processing the radio frequency signals of the standard;

in specific implementation, when an uplink working frequency band and a downlink working frequency band of a certain system are consistent (for example, in a TD-scdma system), the same filter can be used for realizing the functions of uplink filtering and downlink filtering;

in addition, when the uplink working frequency band and the downlink working frequency band of different systems are respectively consistent (such as a WCDMA system and a CDMA2000 system) or close (such as a DCS system and a TD-SCDMA system), a corresponding uplink filter M1 can be designed for the uplink working frequency band, a corresponding downlink filter M2 can be designed for the downlink working frequency band, and the system circuits 1113 corresponding to different systems share one set of uplink filter M1 and downlink filter M2, so that the same working frequency band uses the same filter, thereby simplifying equipment and saving resources;

specifically, the radio frequency signals transmitted and received in the circuits 1113 of different standards can also share one set of receiver M3 and transmitter M4 according to actual conditions, so as to further achieve the purposes of simplifying the device structure and saving resources.

each first standard circuit 72113 is configured to send, in an uplink, an uplink radio frequency signal received from the first standard selector 72112 to the first multi-standard radio frequency processing module 7212; in the downlink, the downlink rf signal received from the first multi-standard rf processing module 7212 is sent to the first standard selector 72112.

Specifically, in order to support processing of signals of multiple systems, the first multi-system amplification module 7211 needs to include multiple first-system circuits 72113, each first-system circuit 72113 is dedicated to processing signals of one system, for example, when the multiple predetermined systems are GSM, WCDMA, and CDMA, respectively, the first multi-system amplification module 7211 needs to include three first-system circuits 72113 for processing GSM signals, WCDMA signals, and CDMA signals, respectively; in addition, the first multi-standard amplification module 7211 uses the first standard selector 72112 to send the signal to the corresponding first standard circuit 72113 for processing according to the standard type of the signal, and in a specific implementation, the first standard selector 72112 is controlled by a software program, can automatically determine the standard type of the signal, and accurately send the signal to the corresponding first standard circuit 72113 for processing.

That is to say, the intermediate transceiver device 72 provided in this embodiment can, in addition to simultaneously supporting multi-system signal processing, enable the intermediate transceiver device 72 to process only single-system signals within a period of time through this setting; therefore, in the array antenna apparatus, each intermediate transceiver device 72 can be set to support only single-system signal processing, and different settings can be performed according to actual situations, for example, one intermediate transceiver device 72 is set to support only CDMA-system processing for a period of time, and the intermediate transceiver device 72 is set to support only GSM-system processing for another period of time, or some intermediate transceiver devices 72 are set to support CDMA-system processing for a period of time, and other intermediate transceiver devices 72 are set to support GSM-system processing for a period of time, so that the array antenna apparatus can have flexible and variable system coverage functions through different setting modes.

in specific implementation, when an uplink working frequency band and a downlink working frequency band of a certain system are consistent (for example, in TD-SCDMA system), the same filter can be used to realize the functions of uplink filtering and downlink filtering;

in addition, when the uplink working frequency bands and the downlink working frequency bands of different systems are respectively consistent (such as a WCDMA system and a CDMA2000 system) or close (such as a DCS system and a TD-SCDMA system), a corresponding first uplink filter C1 can be designed for the uplink working frequency band, a corresponding first downlink filter C2 can be designed for the downlink working frequency band, and circuits corresponding to the different systems share one set of a first uplink filter C1 and a first downlink filter C2, so that the same filters are used in the same working frequency band, thereby simplifying equipment and saving resources;
