本发明涉及无线通信技术， 特别涉及一种进行接入的方法和装置。 背景技术  The present invention relates to wireless communication technologies, and in particular, to a method and apparatus for performing access. Background technique
随着 TD ( Time Division, 时分）频谱资源的增加， 以及芯片技术的飞速 发展， TD***承载和扩容能力也得到极大的提高。 TD-SCDMA( Time Division Synchronized Code Division Multiple Access, 时分同步码分多址 ) ***不仅应 用于 A、 B频段， 而且还将应用于 C频段。  With the increase of TD (Time Division) spectrum resources and the rapid development of chip technology, the capacity of TD system to carry and expand capacity has also been greatly improved. The TD-SCDMA (Time Division Synchronized Code Division Multiple Access) system is applied not only to the A and B bands but also to the C band.
如果 TD-SCDMA***引入 C频段， 那么基站就得同时支持 TD-SCDMA 和 TD-LTE ( Time Division Long Term Evolution, 时分长期演进 ) 两种***。 同一根天线将同时工作在 A、 B、 C三个频段， 而且对于 C频段还将同时收发 TD-SCDMA信号和 TD-LTE信号。  If the TD-SCDMA system introduces the C-band, the base station must support both TD-SCDMA and TD-LTE (Time Division Long Term Evolution) systems. The same antenna will work in the three frequency bands A, B and C at the same time, and will also transmit and receive TD-SCDMA signals and TD-LTE signals simultaneously for the C-band.
TD***的 RRU ( Remote Radio Unit,远端射频装置）上一般有两个光口， 通过不同配置场景可以实现 BBU ( Base Band Unit, 基带装置）和 RRU的多 种配置， 比如单光口不级联， 参见图 1A; 单光口级联， 参见图 1B; 双光口分 担级联， 参见图 1C。  The RRU (Remote Radio Unit) of the TD system generally has two optical ports. The BBU (Base Band Unit) and the RRU can be configured in different configurations. For example, the single optical port is inferior. For connection, see Figure 1A; single optical port cascading, see Figure 1B; dual optical port sharing cascade, see Figure 1C.
目前， RRU上的光口均使用同一标准化接口， RRU需要跟采用相同标准 化接口的 BBU (主站侧）相连完成接入。 而 TD-LTE***中有两种标准化接 口， 即 IR ( Interface between RRU and BBU, RRU和 BBU之间的接口）标准 化接口和 CPRI ( Common Public Radio Interface, 通用公共射频接口）标准化 接口， 这就造成配置 RRU时需要根据主站侧的接口类型进行配置， 从而增加 了配置 RRU的难度。 Currently, the optical ports on the RRU use the same standardized interface, and the RRU needs to connect to the BBU (the primary station side) that uses the same standardized interface to complete the access. In the TD-LTE system, there are two standardized interfaces, namely, an interface between the IR (Interface between RRU and BBU) interfaces and a standardized interface of the CPRI (Common Public Radio Interface). When configuring an RRU, you need to configure it according to the interface type on the primary station side. The difficulty of configuring the RRU.
综上所述， 目前在 RRU接入 BBU时， 需要根据 BBU的接口类型选择合 适的 RRU， 从而增加了接入的难度， 降低了接入的效率。 发明内容  In summary, when the RRU is connected to the BBU, the RRU needs to be selected according to the interface type of the BBU, which increases the difficulty of access and reduces the access efficiency. Summary of the invention

In the embodiment of the present invention, the RU has different standardized interfaces, and the protocol type corresponding to the interface is determined according to the information in the received data, so that when the RRU accesses the BBU, it is not necessary to select an appropriate RRU according to the interface type of the BBU. , each RRU can be accessed, thereby reducing access Difficulty.
下面结合说明书附图对本发明实施例作进一步详细描述。  The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.
如图 2所示， 本发明实施例的 RRU包括： 至少两组接口模块 100、 协议 类型确定模块 110和接入模块 120。  As shown in FIG. 2, the RRU of the embodiment of the present invention includes: at least two sets of interface modules 100, a protocol type determining module 110, and an access module 120.
每组接口模块 100用于接收数据， 其中， RRU中至少有两组接口， 每组 接口中至少有一个接口， 每组接口采用一个接口标准， 至少两组接口采用的 接口标准的种类不少于两种。  Each group of interface modules 100 is configured to receive data. The RRU has at least two interfaces, and each group has at least one interface. Each group interface adopts one interface standard, and at least two types of interfaces adopt interface standards of not less than Two.
协议类型确定模块 110， 用于在一组接口模块 100接收到数据后， 根据接 收到的数据的结构， 确定该数据采用的数据帧协议， 以及根据确定的数据帧 协议， 确定接收该数据的一组接口采用的接口标准。  The protocol type determining module 110 is configured to determine, according to the structure of the received data, a data frame protocol adopted by the data after receiving the data by the interface module 100, and determine, according to the determined data frame protocol, a data receiving the data. The interface standard used by the group interface.
接入模块 120， 用于采用协议类型确定模块 110确定的接口标准， 通过接 收该数据的一组接口模块进行接入。  The access module 120 is configured to adopt an interface standard determined by the protocol type determining module 110, and access is performed by a group of interface modules that receive the data.
至少两组接口采用的接口标准的种类中至少包括： IR接口标准和 CPRI 接口标准。  The types of interface standards used by at least two sets of interfaces include at least: an IR interface standard and a CPRI interface standard.
其中， 协议类型确定模块 110根据接收到的数据的结构确定接收该数据 的一组接口采用的接口标准的方式有多种。 下面列举几种确定接口协议类型 的方式：  The protocol type determining module 110 determines, according to the structure of the received data, a plurality of manners of using the interface standards adopted by the set of interfaces for receiving the data. Here are a few ways to determine the type of interface protocol:
方式一、 协议类型确定模块 110根据接收到的数据中的相邻两个 Comma 头之间的时间长度， 确定接口标准。  Method 1, the protocol type determining module 110 determines the interface standard according to the length of time between two adjacent Comma headers in the received data.
具体的， 预先设定时间长度和数据帧协议的对应关系以及数据帧协议和 接口标准的对应关系， 协议类型确定模块 110确定接收到的数据中的相邻两 个 Comma 头之间的时间长度， 根据预先设定的时间长度和数据帧协议的对 应关系， 确定相邻两个 Comma头之间的时间长度对应的数据帧协议， 根据 预先设定的数据帧协议和接口标准的对应关系， 确定该数据采用的数据帧协 议对应的接口标准， 并将确定的接口标准作为接收该数据的一组接口采用的 接口标准。  Specifically, the correspondence between the length of time and the data frame protocol and the correspondence between the data frame protocol and the interface standard are preset, and the protocol type determining module 110 determines the length of time between two adjacent Comma headers in the received data. Determining, according to a preset time length and a correspondence between data frame protocols, a data frame protocol corresponding to a length of time between two adjacent Comma headers, and determining the correspondence according to a correspondence between a preset data frame protocol and an interface standard. The interface standard corresponding to the data frame protocol adopted by the data, and the determined interface standard is used as an interface standard adopted by a set of interfaces that receive the data.
比如 IR接口协议类型对应的 Comma头之间的时间长度是 25 μβ, 所以可 以设定时间长度 25 对应 IR数据帧协议； 相应的， IR数据帧协议对应 IR 接口标准； For example, the length of time between the Comma headers corresponding to the IR interface protocol type is 25 μβ, so The IR data frame protocol is corresponding to the set time length 25; correspondingly, the IR data frame protocol corresponds to the IR interface standard;
CPRI接口协议类型对应的 Comma头之间的时间长度是 66.67 μδ, 所以可 以设定时间长度 66.67 对应 CPRI数据帧协议； 相应的 , CPRI数据帧协议 对应 CPRI接口标准。 The length of time between the Comma headers corresponding to the CPRI interface protocol type is 66.67 μ δ , so the length of time 66.67 can be set to correspond to the CPRI data frame protocol; correspondingly, the CPRI data frame protocol corresponds to the CPRI interface standard.
需要说明的是， 时间长度和数据帧协议的对应关系可以根据需要进行修 改， 比如 IR接口协议类型对应的 Comma头之间的时间长度如果发生变化， 则可以相应修改 IR接口协议类型对应的时间长度。  It should be noted that the correspondence between the length of the time and the data frame protocol can be modified as needed. For example, if the length of the time between the Comma headers corresponding to the IR interface protocol type changes, the length of the IR interface protocol type can be modified accordingly. .
方式二、 协议类型确定模块 110根据接收到的数据中 Comma头之后， 且 与该 Comma头相邻的数据包中 SGN ( Super Group Number, 超组序号）的数 量， 确定接口标准。  Manner 2: The protocol type determining module 110 determines an interface standard according to the number of SGN (Super Group Number) in the data packet adjacent to the Comma header after the Comma header in the received data.
具体的， 协议类型确定模块 110确定接收到的数据中 Comma头之后， 且 与该 Comma头相邻的数据包中 SGN的数量， 根据预先设定的数量范围和数 据帧协议的对应关系， 确定所述数据包中 SGN的数量所属的数量范围对应的 数据帧协议， 根据预先设定的数据帧协议和接口标准的对应关系， 确定该数 据采用的数据帧协议对应的接口标准， 并将确定的接口标准作为接收该数据 的一组接口采用的接口标准。  Specifically, the protocol type determining module 110 determines the number of SGNs in the data packet adjacent to the Comma header after the Comma header in the received data, and determines the location according to the preset number range and the correspondence relationship of the data frame protocol. The data frame protocol corresponding to the quantity range of the number of SGNs in the data packet, according to the correspondence between the preset data frame protocol and the interface standard, determining an interface standard corresponding to the data frame protocol used by the data, and determining the interface The standard is the interface standard used by a set of interfaces that receive this data.
数据中 Comma 头之后， 且与该 Comma 头相邻的数据包中会有多个 SGN, 即 1、 2、 3.....， 根据接口标准的不同， SGN的数量也不同。  After the Comma header in the data, there are multiple SGNs in the data packet adjacent to the Comma header, namely 1, 2, 3....., and the number of SGNs varies according to the interface standard.
比如 IR接口协议类型对应的 SGN的数量是 200, 所以可以设定数量范围 190 ~ 210对应 IR数据帧协议； 相应的， IR数据帧协议对应 IR接口标准， 当 然可以不查看 SGN的数量， 而是查看最后一个 SGN, IR数据帧协议对应的 最后一个 SGN是 199， 根据最后一个 SGN就可以推导出 SGN的数量， 即 200;  For example, the number of SGNs corresponding to the IR interface protocol type is 200, so the number of 190 to 210 corresponding IR data frame protocols can be set; correspondingly, the IR data frame protocol corresponds to the IR interface standard, and of course, the number of SGNs may not be viewed, but Viewing the last SGN, the last SGN corresponding to the IR data frame protocol is 199. According to the last SGN, the number of SGNs can be derived, that is, 200;
CPRI接口协议类型对应的 SGN的数量是 150， 所以可以设定数量范围 140〜 160对应 CPRI数据帧协议； 相应的， CPRI数据帧协议对应 CPRI接口 标准， 当然可以不查看 SGN的数量， 而是查看最后一个 SGN, CPRI数据帧 协议对应的最后一个 SGN是 149, 根据最后一个 SGN就可以推导出 SGN的 数量， 即 150。 The number of SGNs corresponding to the CPRI interface protocol type is 150, so the number of ranges from 140 to 160 can be set to correspond to the CPRI data frame protocol. Correspondingly, the CPRI data frame protocol corresponds to the CPRI interface standard. Of course, instead of viewing the number of SGNs, Last SGN, CPRI data frame The last SGN corresponding to the protocol is 149. According to the last SGN, the number of SGNs, that is, 150, can be derived.
需要说明的是， 数量范围和数据帧协议的对应关系可以根据需要进行修 改， 比如 IR接口协议类型对应的 SGN的数量如果发生变化， 则可以相应修 改 IR接口协议类型对应的数量范围。  It should be noted that the corresponding relationship between the quantity range and the data frame protocol can be modified as needed. For example, if the number of SGNs corresponding to the IR interface protocol type changes, the number range corresponding to the IR interface protocol type can be modified accordingly.
本发明实施例并不局限于上述两种方式， 其他能够根据接收到的数据中 的信息确定接口协议类型的方式都适用于本发明实施例。  The embodiments of the present invention are not limited to the foregoing two modes, and other manners for determining the interface protocol type according to the information in the received data are applicable to the embodiments of the present invention.
在具体实施过程中， 协议类型确定模块 110在一组接口模块 100接收到 数据后， 会根据数据的 Comma头中的信息还原出 R U帧结构， 从而能够按 照对应的接口标准完成和 BBU侧的数据信息交互。  In a specific implementation process, after receiving the data, the protocol type determining module 110 restores the RU frame structure according to the information in the Comma header of the data, so that the data of the BBU side can be completed according to the corresponding interface standard. Information exchange.
接入模块 120在接入前会先进行超组同步， 同步完成后会根据协议类型 确定模块 110所确定的接口协议类型， 通过接收该数据的一组接口模块进行 接入。  The access module 120 performs super-group synchronization before accessing. After the synchronization is completed, the interface protocol type determined by the module 110 is determined according to the protocol type, and is accessed by a group of interface modules that receive the data.
如图 3所示， 本发明实施例进行接入的方法包括：  As shown in FIG. 3, the method for accessing in the embodiment of the present invention includes:
步骤 301、 RRU通过一组接口接收数据。  Step 301: The RRU receives data through a set of interfaces.
其中 RRU中至少有两組接口， 每组接口中至少有一个接口， 每组接口采 用一个接口标准， 至少两组接口采用的接口标准的种类不少于两种。  There are at least two sets of interfaces in the RRU, and at least one interface in each set of interfaces, each interface adopts one interface standard, and at least two types of interfaces adopt at least two types of interface standards.
步骤 302、 RRU根据接收到的数据的结构， 确定该数据采用的数据帧协 议， 以及根据确定的数据帧协议， 确定接收该数据的一组接口采用的接口标 准。  Step 302: The RRU determines, according to the structure of the received data, a data frame protocol used by the data, and determines, according to the determined data frame protocol, an interface standard used by a group of interfaces that receive the data.
步骤 303、 RRU采用确定的接口标准， 通过接收该数据的一组接口进行 接入。  Step 303: The RRU adopts a determined interface standard, and accesses through a set of interfaces that receive the data.
步骤 302中， RRU根据接收到的数据的结构确定接收该数据的一组接口 采用的接口标准的方式有多种。 下面列举几种确定接口协议类型的方式： 方式一、 RRU根据接收到的数据中的相邻两个 Comma头之间的时间长 度， 确定接口标准。  In step 302, the RRU determines, according to the structure of the received data, a plurality of ways of using the interface standard adopted by the set of interfaces that receive the data. The following describes several ways to determine the type of interface protocol: Method 1: The RRU determines the interface standard based on the length of time between two adjacent Comma headers in the received data.
具体的， 预先设定时间长度和数据帧协议的对应关系以及数据帧协议和 接口标准的对应关系， R U确定接收到的数据中的相邻两个 Comma头之间 的时间长度， 根据预先设定的时间长度和数据帧协议的对应关系， 确定相邻 两个 Comma 头之间的时间长度对应的数据帧协议， 根据预先设定的数据帧 协议和接口标准的对应关系， 确定该数据采用的数据帧协议对应的接口标 准， 并将确定的接口标准作为接收该数据的一组接口采用的接口标准。 Specifically, pre-set the correspondence between the length of time and the data frame protocol, and the data frame protocol and The correspondence between the interface standards, the RU determines the length of time between two adjacent Comma headers in the received data, and determines the relationship between the adjacent two Comma headers according to the preset time length and the correspondence relationship of the data frame protocol. The data frame protocol corresponding to the length of time determines the interface standard corresponding to the data frame protocol adopted by the data according to the correspondence between the preset data frame protocol and the interface standard, and determines the determined interface standard as a group receiving the data. Interface standard used by the interface.
比如 IR接口协议类型对应的 Comma头之间的时间长度是 25 μδ, 所以可 以设定时间长度 25 对应 IR数据帧协议； 相应的， IR数据帧协议对应 IR 接口标准； For example, the length of time between the Comma headers corresponding to the IR interface protocol type is 25 μ δ , so the length of time 25 can be set to correspond to the IR data frame protocol; correspondingly, the IR data frame protocol corresponds to the IR interface standard;
CPRI接口协议类型对应的 Comma头之间的时间长度是 66.67 με, 所以可 以设定时间长度 66.67 对应 CPRI数据帧协议； 相应的， CPRI数据帧协议 对应 CPRI接口标准。  The length of the Comma header corresponding to the CPRI interface protocol type is 66.67 με, so the length of time 66.67 can be set to correspond to the CPRI data frame protocol. Correspondingly, the CPRI data frame protocol corresponds to the CPRI interface standard.
需要说明的是， 时间长度和数据帧协议的对应关系可以根据需要进行修 改， 比如 IR接口协议类型对应的 Comma头之间的时间长度如果发生变化， 则可以相应修改 IR接口协议类型对应的时间长度。  It should be noted that the correspondence between the length of the time and the data frame protocol can be modified as needed. For example, if the length of the time between the Comma headers corresponding to the IR interface protocol type changes, the length of the IR interface protocol type can be modified accordingly. .
方式二、 RRU根据接收到的数据中 Comma头之后， 且与该 Comma头相 邻的数据包中 SGN的数量， 确定接口标准。  Manner 2: The RRU determines an interface standard according to the number of SGNs in the data packet that is adjacent to the Comma header in the received data.
具体的， RRU确定接收到的数据中 Comma头之后， 且与该 Comma头相 邻的数据包中 SGN的数量， 根据预先设定的数量范围和数据帧协议的对应关 系， 确定所述数据包中 SGN的数量所属的数量范围对应的数据帧协议， 根据 预先设定的数据帧协议和接口标准的对应关系， 确定该数据采用的数据帧协 议对应的接口标准， 并将确定的接口标准作为接收该数据的一组接口采用的 接口标准。  Specifically, the RRU determines the number of SGNs in the data packet adjacent to the Comma header after the Comma header in the received data, and determines the data packet according to a preset relationship between the quantity range and the data frame protocol. The data frame protocol corresponding to the quantity range of the quantity of the SGN, according to the correspondence between the preset data frame protocol and the interface standard, determining the interface standard corresponding to the data frame protocol adopted by the data, and determining the interface standard as the receiving The interface standard used by a set of interfaces for data.
数据中 Comma 头之后， 且与该 Comma 头相邻的数据包中会有多个 SGN, 即 1、 2、 3.....， 根据接口标准的不同， SGN的数量也不同。  After the Comma header in the data, there are multiple SGNs in the data packet adjacent to the Comma header, namely 1, 2, 3....., and the number of SGNs varies according to the interface standard.
比如 IR接口协议类型对应的 SGN的数量是 200， 所以可以设定数量范围 190 ~ 210对应 IR数据帧协议； 相应的， IR数据帧协议对应 IR接口标准， 当 然可以不查看 SGN的数量， 而是查看最后一个 SGN， IR数据帧协议对应的 最后一个 SGN是 199, 根据最后一个 SGN就可以推导出 SGN的数量， 即 200; For example, the number of SGNs corresponding to the IR interface protocol type is 200, so the number of 190 to 210 corresponding IR data frame protocols can be set; correspondingly, the IR data frame protocol corresponds to the IR interface standard, and of course, the number of SGNs may not be viewed, but View the last SGN, corresponding to the IR data frame protocol The last SGN is 199. According to the last SGN, the number of SGNs can be derived, that is, 200;
CPRI接口协议类型对应的 SGN的数量是 150， 所以可以设定数量范围 140 ~ 160对应 CPRI数据帧协议； 相应的， CPRI数据帧协议对应 CPRI接口 标准， 当然可以不查看 SGN的数量， 而是查看最后一个 SGN, CPRI数据帧 协议对应的最后一个 SGN是 149， 根据最后一个 SGN就可以推导出 SGN的 数量， 即 150。  The number of SGNs corresponding to the CPRI interface protocol type is 150, so the CPRI data frame protocol can be set in the range of 140 to 160. Correspondingly, the CPRI data frame protocol corresponds to the CPRI interface standard. Of course, instead of viewing the number of SGNs, In the last SGN, the last SGN corresponding to the CPRI data frame protocol is 149. According to the last SGN, the number of SGNs, that is, 150, can be derived.
需要说明的是， 数量范围和数据帧协议的对应关系可以根据需要进行修 改， 比如 IR接口协议类型对应的 SGN的数量如果发生变化， 则可以相应修 改 IR接口协议类型对应的数量范围。  It should be noted that the corresponding relationship between the quantity range and the data frame protocol can be modified as needed. For example, if the number of SGNs corresponding to the IR interface protocol type changes, the number range corresponding to the IR interface protocol type can be modified accordingly.
本发明实施例并不局限于上述两种方式， 其他能够根据接收到的数据中 的信息确定接口协议类型的方式都适用于本发明实施例。  The embodiments of the present invention are not limited to the foregoing two modes, and other manners for determining the interface protocol type according to the information in the received data are applicable to the embodiments of the present invention.
在具体实施过程中， RRU通过一组接口接收到数据后， 会根据数据的 Comma头中的信息还原出 RRU帧结构， 从而能够按照对应的接口标准完成 和 BBU侧的数据信息交互。  In the specific implementation process, after receiving the data through a set of interfaces, the RRU restores the RRU frame structure according to the information in the Comma header of the data, so that the data information of the BBU side can be exchanged according to the corresponding interface standard.
步骤 303中 , RRU在接入前会先进行超組同步， 同步完成后根据确定的 接口协议类型， 通过接收该数据的一组接口模块进行接入。 即接入完成后， 就可以根据确定的接口协议类型， 通过对应的一组接口进行 数据传输。  In step 303, the RRU performs the super group synchronization before the access, and after the synchronization is completed, according to the determined interface protocol type, access is performed by a group of interface modules that receive the data. That is, after the access is completed, data transmission can be performed through a corresponding set of interfaces according to the determined interface protocol type.
以 RRU中有两组接口为例， 本发明实施例对于高速率传输， 不管单、 多 天线， 将 RRU中的两组接口配置成不同的接口标准， 即其中一组端口配制成 IR接口标准， 另一组接口配制成 CPRI接口标准， 以满足级联和不级联的灵 活接入的需求。  For example, in the embodiment of the present invention, the two sets of interfaces in the RRU are configured as different interface standards, that is, one of the ports is configured as an IR interface standard for high-rate transmission, regardless of single or multiple antennas. Another set of interfaces is configured as a CPRI interface standard to meet the needs of flexible access without cascading and non-cascading.
比如： 对于单天线 4.9152 Gbps传输， 一个 4.9152 Gbps IR接口最多支持 96个 IQ数据。 以 TD-SCDMA***码片速率 1.28 MHz, 载波带宽 1.6 MHz 计算所需 IQ数目， 可知 A频段 20 MHz, 需占用 12个栽波， 即 12个 IQ数 据； B频段 15 MHz， 需占用 9个载波， 即 9个 IQ数据； C频段 TD lO MHz, 需占用 6个载波， 即 6个 IQ数据； C频段 LTE两天线 20 MHz, 需占用 48 个 IQ数据， 合计 79个 IQ数据。 由于小于最大容量 96个 IQ数据， 所以单天 线的一个接口就可满足实际应用需求， 对于其他速率传输的 RRU可以通过需 要修改 CA (载波天线） 的配置满足需求。 For example: For a single antenna 4.9152 Gbps transmission, a 4.9152 Gbps IR interface supports up to 96 IQ data. Calculate the required number of IQs at a chip rate of 1.28 MHz and a carrier bandwidth of 1.6 MHz in the TD-SCDMA system. It can be seen that the A-band 20 MHz requires 12 carriers, that is, 12 IQ numbers. According to; B-band 15 MHz, it takes 9 carriers, that is, 9 IQ data; C-band TD lO MHz takes 6 carriers, that is, 6 IQ data; C-band LTE two antennas 20 MHz, takes 48 IQs Data, totaling 79 IQ data. Because it is less than the maximum capacity of 96 IQ data, one interface of a single antenna can meet the needs of practical applications. For other rate transmissions, the RRU can meet the requirements by modifying the configuration of the CA (carrier antenna).
其中， IQ数据是基带数据 I路和 0路（两路相位相差 90度)数据的总称， CA数据也是用 IQ表示的， 修改 CA配置就是修改 IQ数据个数， 使其满足不 同速率容量需求。  Among them, the IQ data is the general name of the data of the baseband data I and 0 (the phase difference between the two channels is 90 degrees), and the CA data is also represented by IQ. Modifying the CA configuration is to modify the number of IQ data to meet the different rate capacity requirements.
当不考虑单天线级联应用场景时， RRU不接设备的接口将处于闲置不使 用状态， 因此， 当将另一个接口设计成 CPRI接口标准， 就能基于同一 RRU 软硬件平台， 同时支持两种接口标准接入主站。 当主站侧是 IR接口标准时， 只需用对应的 IR接口接主站； 如果主站侧是 CPRI接口标准， 只需用对应的 CPRI接口接主站， 参见图 4A和 4B。  When the single antenna cascading application scenario is not considered, the interface of the RRU device that is not connected to the device will be idle and unused. Therefore, when the other interface is designed as the CPRI interface standard, it can be based on the same RRU hardware and software platform. The interface standard is connected to the primary station. When the primary station side is the IR interface standard, simply connect the primary station with the corresponding IR interface; if the primary station side is the CPRI interface standard, simply connect the primary station with the corresponding CPRI interface, see Figures 4A and 4B.
如果单天线支持级联场景， 若主站侧是 IR标准， 用 R U的 IR接口接主 站， 而 CPRI接口接下一级 RRU的 CPRI接口， 依次类推就可实现各级 RRU 的级联； 如果主站侧是 CPRI标准， 则用 CPRI接口接主站， 而 IR接口接下 一级 RRU的 IR接口， 依次类推也可实现各级 RRU的级联， 参见图 5A和 5B。  If the single antenna supports the cascading scenario, if the primary station side is the IR standard, the IR interface of the RU is connected to the primary station, and the CPRI interface is connected to the CPRI interface of the next-level RRU, and so on, the cascading of the RRUs of each level can be implemented; The primary station side is the CPRI standard, and the CPRI interface is connected to the primary station, and the IR interface is connected to the IR interface of the next-level RRU, and so on, the cascading of the RRUs of each level can also be implemented, see FIGS. 5A and 5B.
其中图 4A ~ 5B中都是一组接口中有一个接口， 还有可能是一组接口 中有两个接口， 比如釆用分担级联的方式， 参见图 6。  In Figure 4A ~ 5B, there is one interface in a group of interfaces, and there may be two interfaces in a group of interfaces, such as the way of sharing and cascading, see Figure 6.
其中， 分担级联的方式与上面的方式类似， 只是将一个接口传输的数据 通过两个接口传输， RRU接收到两个接口的数据后，会合成一个完整的数据。  The manner of sharing the cascading is similar to the above manner, except that the data transmitted by one interface is transmitted through two interfaces, and after receiving the data of the two interfaces, the RRU synthesizes a complete data.
