下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

首先，参见图1，图1是本申请实施例提供的一种无线回传一体化基站的示意图。如图1所示，可以看出，该无线回传一体化基站100包括片上系统101和射频集成装置102。其中，片上系统101包括主控和传输1011、基站处理芯片1012。一般来说，主控和传输1011可以包括基带处理单元(base band unite，BBU)、时钟分发、电源分发和空中接口等。基站处理芯片1012例如可以为专用集成电路(application-specific integrated circuit，ASIC)。可以看出，片上系统101可以支持主控、传输、第三代移动通信技术(the 3rdgeneration mobile communication technology，3G)、第四代移动通信技术(the 4th generation mobile  communication technology，4G)、无线回传技术(Relay)的L1、L2、L3基带处理和数字中频处理等。其中，L1基带处理主要是关于物理层(port physical layer，PHY)的处理，L2基带处理主要是关于媒体接入控制(media access control，MAC)或无线链路控制(radio link control，RLC)的处理、L3基带处理主要是关于无线资源控制(radio resource control，RRC)。Relay一般也基于LTE制式实现。射频集成装置102可以包括射频集成芯片1021和收发机装置1022。其中，射频集成芯片1021可以集成射频集成电路(radio frequency integrated circuit，RFIC)、射频本振、发送(transmit，TX)DAC、接收(receive，RX)ADC等。另外，射频集成芯片1021可以支持收发信机单元(transmission receiver unit，TRX)等。射频集成芯片1021主要采用零中频(zero intermediate frequency，ZIF)架构，可以支持TX通道、RX通道以及反馈(faceback，FB)通道等。收发机装置1022可以包括Relay收发机射频链路1022a、LTE或UMTS收发机射频链路1022b、Relay天线和LTE天线。First, referring to Fig. 1, Fig. 1 is a schematic diagram of a wireless backhaul integrated base station provided by an embodiment of the present application. As shown in FIG. 1, it can be seen that the integrated wireless backhaul base station 100 includes a system on chip 101 and a radio frequency integrated device 102. Among them, the system on chip 101 includes a main control and transmission 1011 and a base station processing chip 1012. Generally speaking, the main control and transmission 1011 may include a baseband unit (BBU), clock distribution, power distribution, and air interface. The base station processing chip 1012 may be, for example, an application-specific integrated circuit (ASIC). It can be seen that the system-on-chip 101 can support master control, transmission, the 3rd generation mobile communication technology (3G), the 4th generation mobile communication technology (4G), and wireless backhaul. Technology (Relay) L1, L2, L3 baseband processing and digital intermediate frequency processing, etc. Among them, L1 baseband processing is mainly about physical layer (port physical layer, PHY) processing, and L2 baseband processing is mainly about media access control (MAC) or radio link control (RLC). Processing and L3 baseband processing are mainly related to radio resource control (RRC). Relay is also generally implemented based on the LTE standard. The radio frequency integrated device 102 may include a radio frequency integrated chip 1021 and a transceiver device 1022. Among them, the radio frequency integrated chip 1021 may integrate a radio frequency integrated circuit (RFIC), a radio frequency local oscillator, a transmit (TX) DAC, a receive (receive, RX) ADC, and so on. In addition, the radio frequency integrated chip 1021 can support a transceiver unit (transmission receiver unit, TRX) and the like. The radio frequency integrated chip 1021 mainly adopts a zero intermediate frequency (ZIF) architecture, which can support TX channels, RX channels, and feedback (faceback, FB) channels. The transceiver device 1022 may include a relay transceiver radio frequency link 1022a, an LTE or UMTS transceiver radio frequency link 1022b, a relay antenna, and an LTE antenna.

进一步的，结合图1，参见图2，图2是图1中基站处理芯片1012对Relay数据、通用移动通信系统(universal mobile telecommunications system，UMTS)数据、LTE数据处理的示意图。其中，Relay数据可以包括Relay下行数据和Relay上行数据。可以理解的，Relay下行数据可以为利用Relay传输的下行数据，Relay上行数据可以为利用Relay传输的上行数据。UMTS数据可以包括UMTS下行数据和UMTS上行数据。可以理解的，UMTS下行数据可以为利用UMTS传输的下行数据，UMTS上行数据可以为利用UMTS传输的上行数据。LTE数据可以包括LTE下行数据和LTE上行数据。可以理解的，LTE下行数据可以为利用LTE传输的下行数据，LTE上行数据可以为利用LTE传输的上行数据。如图2所示，可以看出，基站处理芯片1012可以包括数字自动增益控制(digital automatic gain control，DAGC)、采样率转换器(sample rate converter，SRC)、数字控制振荡器(numerically controlled oscillator，NCO)、数字预失真(digital pre-distortion，DPD)、自动增益控制(analog auto gain control，AAGC)、模数转换器(analog-to-digital converter，ADC)和数模转换器(digital to analog converter，DAC)等。另外，针对Relay下行数据、UMTS下行数据和LTE下行数据，需要经过SRC、NCO、合路、削波、DPD、DAC等处理。针对Relay上行数据、UMTS上行数据和LTE上行数据，需要经过ADC、AAGC、分路、NCO、SRC等处理。其中，NCO相当于传统中频调制解调中的本振。削波可以对数据峰值进行平滑抑制处理，保护功放。DPD保证功放的线性，AAGC用于对ADC处理后的数据进行功率统计，根据动态范围的门限，计算衰减值通过模拟衰减器进行调整。Further, referring to FIG. 1 and FIG. 2, FIG. 2 is a schematic diagram of the base station processing chip 1012 in FIG. 1 processing Relay data, universal mobile telecommunications system (UMTS) data, and LTE data. Among them, Relay data may include Relay downlink data and Relay uplink data. It can be understood that the relay downlink data may be downlink data transmitted by the relay, and the relay uplink data may be uplink data transmitted by the relay. UMTS data may include UMTS downlink data and UMTS uplink data. It is understandable that the UMTS downlink data may be downlink data transmitted using UMTS, and the UMTS uplink data may be uplink data transmitted using UMTS. LTE data may include LTE downlink data and LTE uplink data. It is understandable that LTE downlink data may be downlink data transmitted using LTE, and LTE uplink data may be uplink data transmitted using LTE. As shown in Figure 2, it can be seen that the base station processing chip 1012 may include digital automatic gain control (DAGC), sample rate converter (SRC), and digitally controlled oscillator (DAGC). NCO), digital pre-distortion (digital pre-distortion, DPD), automatic gain control (analog auto gain control, AAGC), analog-to-digital converter (ADC) and digital-to-analog converter, DAC) and so on. In addition, for Relay downlink data, UMTS downlink data, and LTE downlink data, SRC, NCO, combining, clipping, DPD, DAC and other processing are required. For Relay uplink data, UMTS uplink data, and LTE uplink data, it needs to be processed by ADC, AAGC, branch, NCO, SRC, etc. Among them, NCO is equivalent to the local oscillator in traditional IF modulation and demodulation. Clipping can smoothly suppress the peak of the data to protect the power amplifier. DPD guarantees the linearity of the power amplifier. AAGC is used to perform power statistics on the data processed by the ADC. According to the threshold of the dynamic range, the calculated attenuation value is adjusted by an analog attenuator.

结合图1和图2，可以看出，目前，无线回传一体化基站多采用专用集成电路(application-specific integrated circuit，ASIC)片上系统(system-on-a-chip，SOC)芯片设计。通常来说，该芯片可以集成长期演进(long termrvolution，LTE)和无线回传(Relay)技术等处理功能，另外，Relay技术也是基于LTE制式实现的。可以看出，现有技术中，无线回传一体化基站的集成度高，通常只支持LTE制式，很难在一种无线通信制式的基础上实现另一种无线通信制式。因此，现有的无线回传一体化基站扩展性差，难以支持多种制式。Combining Fig. 1 and Fig. 2, it can be seen that, currently, the wireless backhaul integrated base station mostly adopts application-specific integrated circuit (ASIC) system-on-a-chip (SOC) chip design. Generally speaking, the chip can integrate processing functions such as long term evolution (LTE) and wireless backhaul (Relay) technology. In addition, the Relay technology is also implemented based on the LTE standard. It can be seen that in the prior art, the integrated wireless backhaul base station has a high degree of integration, and usually only supports the LTE standard, and it is difficult to implement one wireless communication standard on the basis of another wireless communication standard. Therefore, the existing integrated wireless backhaul base stations have poor scalability and are difficult to support multiple standards.

基于此，本申请实施例提出一种通信装置以解决上述问题，下面对本申请实施例进行详细介绍。Based on this, an embodiment of the present application proposes a communication device to solve the above-mentioned problem. The following describes the embodiment of the present application in detail.

As shown in FIG. 3, the communication device 300 includes a system on chip 301, a radio frequency integration device 302, and a sampling rate bandwidth adjustment device 303. Among them, the system on chip 301 includes a main control and transmission 3011, a base station processing chip 3012.

It can be understood that the communication device 300 may be an integrated wireless backhaul base station.

进一步的，该基站处理芯片3012，用于向采样速率带宽调整装置303传输第一GSM下行数据。可以理解的，第一GSM下行数据可以为利用GSM传输的下行数据。即进一步的，第一GSM下行数据可以为主控数据，该主控数据可以包括业务数据、控制面信令数据和跳频管理数据，业务数据例如可以为语音数据。Further, the base station processing chip 3012 is used to transmit the first GSM downlink data to the sampling rate bandwidth adjustment device 303. It can be understood that the first GSM downlink data may be downlink data transmitted using GSM. That is, further, the first GSM downlink data may be main control data, and the main control data may include service data, control plane signaling data, and frequency hopping management data, and the service data may be voice data, for example.

需要说明的，基站处理芯片3012可以通过周边装置互连高速(peripheral component interconnect express，PCIE)接口或串行千兆位媒质独立接口(serial gigabit media independent interface，SGMII)向采样速率带宽调整装置303传输第一GSM下行数据。It should be noted that the base station processing chip 3012 can transmit to the sampling rate bandwidth adjustment device 303 through the peripheral component interconnect express (PCIE) interface or the serial gigabit media independent interface (SGMII). The first GSM downlink data.

其中，若基站处理芯片3012通过PCIE接口向采样速率带宽调整装置303传输第一GSM下行数据，那么，第一GSM下行数据为包括主控数据的事务层报文(transaction layer packet，TLP)。若基站处理芯片3012通过SGMII接口向采样速率带宽调整装置303传输第一GSM下行数据，那么，第一GSM下行数据为包括主控数据的网际互连协议(internet protocol，IP)报文。Wherein, if the base station processing chip 3012 transmits the first GSM downlink data to the sampling rate bandwidth adjustment device 303 through the PCIE interface, then the first GSM downlink data is a transaction layer packet (TLP) including master control data. If the base station processing chip 3012 transmits the first GSM downlink data to the sampling rate bandwidth adjustment device 303 through the SGMII interface, then the first GSM downlink data is an internet protocol (IP) packet including master control data.

进一步的，该采样速率带宽调整装置303，用于向基站处理芯片3012发送第二GSM下行数据，该第二GSM下行数据是对第一GSM下行数据的采样速率和带宽进行调整后确定的。Further, the sampling rate bandwidth adjusting device 303 is configured to send second GSM downlink data to the base station processing chip 3012, and the second GSM downlink data is determined after adjusting the sampling rate and bandwidth of the first GSM downlink data.

需要说明的，采样速率带宽调整装置303可以通过类通用公共无线电接口(similar/simplecommon public radio interface，CPRI)向基站处理芯片3012发送第二GSM下行数据。It should be noted that the sampling rate bandwidth adjustment device 303 may send the second GSM downlink data to the base station processing chip 3012 through a similar/simple common public radio interface (CPRI).

可选的，该第二GSM下行数据的采样速率和带宽可以满足LTE下行数据的采样速率和带宽，也可以满足UMTS下行数据的采样速率和带宽，还可以满足通过(new radio nodeB,gNB)传输的下行数据的采样速率和带宽，在此不做限制。Optionally, the sampling rate and bandwidth of the second GSM downlink data can meet the sampling rate and bandwidth of LTE downlink data, can also meet the sampling rate and bandwidth of UMTS downlink data, and can also meet the requirements of (new radio nodeB, gNB) transmission The sampling rate and bandwidth of the downstream data are not limited here.

举例来说，第二GSM下行数据的采样速率为650兆位/秒(million bits per second，Mbps)，第二GSM下行数据的带宽为5兆赫(mega hertz，MHz)。For example, the sampling rate of the second GSM downlink data is 650 megabits/second (million bits per second, Mbps), and the bandwidth of the second GSM downlink data is 5 megahertz (MHz).

可以看出，上述技术方案中，基站处理芯片向采样速率带宽调整装置传输GSM下行数据，实现让采样速率带宽调整装置对GSM下行数据的采样速率和带宽进行调节，从而让只支持LTE制式的基站处理芯片可以支持对GSM下行数据的处理，也解决了现有的无线回传一体化基站只支持LTE制式、扩展性差、难以支持多种制式的问题。同时，节省了硬件成本。It can be seen that in the above technical solution, the base station processing chip transmits GSM downlink data to the sampling rate and bandwidth adjustment device, so that the sampling rate and bandwidth adjustment device can adjust the sampling rate and bandwidth of the GSM downlink data, so that the base station that only supports the LTE standard The processing chip can support the processing of GSM downlink data, and also solves the problem that the existing wireless backhaul integrated base station only supports the LTE standard, has poor scalability, and is difficult to support multiple standards. At the same time, hardware costs are saved.

参见图4，图4是图3中通过基站处理芯片3012、采样速率带宽调整装置303对Relay数据、UMTS数据、LTE数据、GSM数据处理的示意图。可以理解的，关于基站处理芯片3012可以参考图2中的基站处理芯片1012。另外，针对Relay数据、UMTS数据、LTE数据，也可以参考图2中关于Relay数据、UMTS数据、LTE数据的内容。Referring to FIG. 4, FIG. 4 is a schematic diagram of the processing of Relay data, UMTS data, LTE data, and GSM data by the base station processing chip 3012 and the sampling rate bandwidth adjustment device 303 in FIG. 3. It can be understood that, for the base station processing chip 3012, reference may be made to the base station processing chip 1012 in FIG. 2. In addition, for Relay data, UMTS data, and LTE data, reference may also be made to the contents of Relay data, UMTS data, and LTE data in FIG. 2.

结合图4，可以看出，针对第一GSM下行数据，需要先传输至采样速率带宽调整装置303中的FPGA装置3031，再传输至GSM基带处理装置3032，当GSM基带处理装置3032完成L1基带处理之后，再传输至FPGA装置3031，最后再返回至基站处理芯片3012。具体的，结合图4，可以理解的，第一GSM下行数据需要先按照图4中401a至404a的传输路径进行处理后，再经过SRC、NCO、合路、削波、DPD、DAC等处理。即，基站处理芯片3012需要先将第一GSM下行数据传输至FPGA装置3031中进行处理，得到第三GSM下行数据；FPGA装置3031再将第三GSM下行数据传输至GSM基带处理装置3032；GSM基带处理装置3032可以对第三GSM下行数据完成L1基带处理，得到第一基带IQ数据；GSM基带处理装置3032再将第一基带IQ数据传输至FPGA装置3031进行处理后，得到第二GSM下行数据；FPGA装置3031接着将第二GSM下行数据传输至基站处理芯片3012；基站处理芯片3012再对第二GSM下行数据进行SRC、NCO、合路、削波、DPD、DAC等处理。4, it can be seen that the first GSM downlink data needs to be transmitted to the FPGA device 3031 in the sampling rate bandwidth adjustment device 303, and then transmitted to the GSM baseband processing device 3032. When the GSM baseband processing device 3032 completes the L1 baseband processing After that, it is transmitted to the FPGA device 3031, and finally returned to the base station processing chip 3012. Specifically, in conjunction with FIG. 4, it can be understood that the first GSM downlink data needs to be processed according to thetransmission path 401a to 404a in FIG. That is, the base station processing chip 3012 needs to first transmit the first GSM downlink data to the FPGA device 3031 for processing to obtain the third GSM downlink data; the FPGA device 3031 then transmits the third GSM downlink data to the GSM baseband processing device 3032; GSM baseband The processing device 3032 can perform L1 baseband processing on the third GSM downlink data to obtain the first baseband IQ data; the GSM baseband processing device 3032 then transmits the first baseband IQ data to the FPGA device 3031 for processing, and obtains the second GSM downlink data; The FPGA device 3031 then transmits the second GSM downlink data to the base station processing chip 3012; the base station processing chip 3012 then performs SRC, NCO, combining, clipping, DPD, DAC and other processing on the second GSM downlink data.

具体的，向基站处理芯片3012发送第二GSM下行数据，FPGA装置3031，用于对第一GSM下行数据进行组帧，得到第三GSM下行数据，将第三GSM下行数据传输至GSM基带处理装置3032。GSM基带处理装置3032，用于对第三GSM下行数据进行L1基带处理，得到两路正交的第一基带IQ数据，将第一基带IQ数据传输至FPGA装置3031；FPGA装置3031，还用于向基站处理芯片传输第二GSM下行数据，以及将第二GSM下行数据传输至基站处理芯片3012。Specifically, the second GSM downlink data is sent to the base station processing chip 3012, and the FPGA device 3031 is used to frame the first GSM downlink data to obtain the third GSM downlink data, and transmit the third GSM downlink data to the GSM baseband processing device 3032. The GSM baseband processing device 3032 is used to perform L1 baseband processing on the third GSM downlink data to obtain two orthogonal first baseband IQ data, and transmit the first baseband IQ data to the FPGA device 3031; the FPGA device 3031 is also used for The second GSM downlink data is transmitted to the base station processing chip, and the second GSM downlink data is transmitted to the base station processing chip 3012.

其中，在拓展第一基带IQ数据的位宽时，一般对第一基带IQ数据的低位补零。在对第二基带IQ数据进行数字内插滤波时，可以采用6倍内插滤波。Wherein, when the bit width of the first baseband IQ data is expanded, the low bits of the first baseband IQ data are generally filled with zeros. When performing digital interpolation filtering on the second baseband IQ data, 6-fold interpolation filtering can be used.
