Description

通信设备和长期演进系统中基站回传的方法
本申请要求于2014年03月10日提交中国专利局、申请号为201410085813.5、发明名称为“通信设备和长期演进系统中基站回传的方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
【技术领域】
本发明涉及无线通信技术领域，特别是涉及一种通信设备和长期演进LTE系统中基站回传的方法。
【背景技术】
基站的回传(backhaul)指在移动无线接入网（Radio Access Network，RAN）层，通过多种物理媒介在基站和基站控制器之间建立一个安全可靠的电路传输手段。由于所有客户终端通过RAN接入移动网络、获得移动业务，因此，基站的回传的网络质量直接影响运营商是否能够快速响应业务发展需求。
随着长期演进（Long Term Evolution, LTE）技术的不断发展，低功率、小覆盖的演进型基站（evolved Node B，eNB）逐渐成为容量扩展的主要手段。由于eNB站点数目不断增加，相应的网络部署和维护问题日益凸显。
eNB回传包括eNB之间的传输和eNB与移动管理实体（Mobility Management Entity，MME）/服务网关（Serving Gateway，S-GW）之间的传输。图1现有技术的LTE系统中eNB的回传的示意图。如图1所示，eNB回传包括S1接口和X2接口，采用光纤方式。其中，S1是eNB和MME/SGW之间的接口，S1接口允许一个eNB连接到多个MME/SGW POOL（池），实现负载均衡、冗灾等。每个eNB支持最多16个S1接口。X2接口是相邻eNB间的分布式接口，主要用于移动性管理和相邻小区的干扰抑制，每个eNB可定义32个X2接口，实际部署时相邻基站数量由覆盖情况决定。由于eNB的回传采用传统的光纤方式，建设周期长、成本高。
【发明内容】

【附图说明】
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。其中：

图7是本发明第二实施例的LTE系统中通信设备的结构示意图。
【具体实施方式】
下面结合附图和实施方式对本发明进行详细说明。
首先请参见图2，LTE系统包括第一基站10、第二基站20以及MME/S-GW 30，第一基站10与第二基站20之间的X2接口，以及第二基站20与MME/S-GW 30之间的S1接口都采用无线传输方式。需要说明的是，基站和核心网之间为了实现回传，一般有专门的传输设备，包括具有天线的无线传输设备（微波等），以进行无线传输。
在本实施例中，第一通信设备可以是第一基站10，为从基站，通过第二基站20进行回传，而相应地，第二通信设备是第二基站20，为主基站，并且具有与MME/S-GW 30之间形成无线回传信道的能力。或者，第一通信设备可以是第二基站20，并且具有与MME/S-GW 30之间形成无线回传信道的能力，而相应地，第二通信设备是MME/S-GW 30。图中的U表示上行子帧，D表示下行子帧，S表示特殊子帧，第一基站10通过第二基站20进行回传的同时，可以与对应的用户设备（图未示）进行通信。
第一通信设备确定第一类帧中至少一个传输子帧，第一类帧由第一通信设备生成，并且是长期演进系统中任一种子帧配置的时分双工(Time Division Duplexing，TDD)帧，传输子帧为第一类帧中与第二类帧中的上行子帧对应的下行子帧，或者，第一类帧中与第二类帧中的下行子帧对应的上行子帧，其中，第二类帧是由第二通信设备根据第一类帧进行子帧偏移后得到的。第一类帧中除传输子帧之外的其他子帧确定为接入子帧，如此第一类帧中的各子帧被划分为传输子帧和接入子帧。第一通信设备通过接入子帧与用户设备传输信息。第一通信设备通过传输子帧与第二通信设备传输信息。具体地，第一类帧的传输子帧和第二类帧的传输子帧形成第一通信设备与第二通信设备之间的无线回传信道，第一通信设备利用该无线回传信道接收第二通信设备发送的回传信息和向第二通信设备发送回传信息。在LTE系统中采用的是混合自动重传请求（Hybrid Automatic Repeat Request，HARQ）的无线传输技术，而上述过程中没有改变第一类帧和第二类帧原来的时序。同时，如果第一类帧与第二类帧没有关联起来，例如第一类帧中与第二类帧中的下行子帧对应的上行子帧是用于接收其他通信设备如终端，而非第二通信设备的传输信息，但是由于帧格式相同，在实际传输过程中，第一类帧中与第二类帧中的下行子帧对应的上行子帧可能会错误地接收第二通信设备发送的信息，同样地第二类帧中与第一类帧中的下行子帧对应的上行子帧可能会错误地接收第一通信设备发送的信息，如此会造成上下行的干扰。而在本发明实施例中，第一类帧中的传输子帧的下行子帧与第二类帧中的传输子帧的上行子帧对应，第一类帧中的传输子帧的上行子帧与第二类帧中的传输子帧的下行子帧对应，即第一类帧中与第二类帧中的下行子帧对应的上行子帧是用于接收第二通信设备发送的信息，以使第二通信设备通过第一通信设备进行回传，从而能够将普通长期演进系统中 eNB之间可能存在的上下行干扰转化为互助传输。
在本发明实施例中，通过第一通信设备确定第一类帧中至少一个传输子帧，第一类帧由第一通信设备生成，并且是长期演进系统中任一种子帧配置的时分双工帧，传输子帧为第一类帧中与第二类帧中的上行子帧对应的下行子帧，或者，第一类帧中与第二类帧中的下行子帧对应的上行子帧，其中，第二类帧是由第二通信设备根据第一类帧进行子帧偏移后得到的，如此，实现对应子帧上的基带优化，保持了HARQ时序，将普通长期演进系统中eNB之间可能存在的上下行干扰转化为互助传输，第一通信设备通过传输子帧与第二通信设备传输信息，利用长期演进系统中eNB自身资源，实现无线方式的基站回传，大大降低了网络部署时间和成本。
在更具体的实施例中，第一类帧和第二类帧为LTE系统中任一种子帧配置的LTE TDD帧。LTE TDD帧长10ms，包括10个子帧，为子帧0～9，LTE TDD 帧包括2个半帧(half-frame)，每个半帧长5ms，每个半帧包括5个子帧，每个子帧长lms。在一个LTE TDD帧中包括的10个子帧中，包括标准子帧和特殊子帧，特殊子帧包括三个域(field)，分别为下行导频时隙(Downlink Pilot Time Slot，DwPTS)，保护间隔(Guard Period，GP)和上行导频时隙(Uplink Pilot Time Slot，UpPTS)。在LTE TDD 系统中，对于LTE TDD 帧，共有7种上行/下行子帧配置(Uplink/Downlink subframeconfiguration)，LTE系统中的7种上行/下行子帧配置的LTE TDD帧记为0～6。
在本发明实施例中，第一类帧为LTE系统中子帧配置为1的LTE TDD 帧，第二类帧为LTE 系统中子帧配置为1的LTE TDD 帧向前或向后偏移预定数量个子帧的帧。第一类帧也可以为LTE 系统中子帧配置为2的LTE TDD 帧，对应的，第二类帧为LTE 系统中子帧配置为2的LTE TDD 帧向前或向后偏移预定数量个子帧的帧。其中，预定数量为正整数，不包括帧长的整数倍。在本发明的其它实施例中，第一类帧可以为LTE系统中子帧配置为0~6的任意一个的LTE TDD 帧，而第二类帧为第一类帧对应向前或向后偏移预定数量个子帧后得到的帧，取第一类帧中，与第二类帧中的上行子帧对应的下行子帧，以及与第二类帧中的下行子帧对应的上行子帧为第一类帧中的传输子帧，其余子帧为第一类帧中的接入子帧，第二类帧中对应的上行子帧和下行子帧为第二类帧中的传输子帧，其余子帧为第二类帧中的接入子帧。
如图3所示，第一类帧为LTE系统中上行下行子帧配置为1的LTE TDD帧，即此时第一类帧的帧结构为：第7子帧为上行子帧，第8子帧为上行子帧，第9子帧为下行子帧，第0子帧为下行子帧，第1子帧为特殊子帧，第2子帧为上行子帧，第3子帧为上行子帧，第4子帧为下行子帧，第5子帧为下行子帧，第6子帧为特殊子帧。由于第二类帧与第一类帧相比，仅是在时域上进行了偏移，因此，第二类帧的帧结构并没有发生变化，第二类帧的结构和第一类帧的结构相同。在本实施例中，第二类帧为LTE系统中子帧配置为1的LTE TDD帧向前偏移3个子帧的帧。因此，第二类帧的帧结构为：第0子帧为下行子帧，第1子帧为特殊子帧，第2子帧为上行子帧，第3子帧为上行子帧，第4子帧为下行子帧，第5子帧为下行子帧，第6子帧为特殊子帧，第7子帧为上行子帧，第8子帧为上行子帧，第9子帧为下行子帧。在同一个帧周期中，第二类帧与第一类帧不同，即在同一个帧周期中，第一类帧的子帧与所对应的第二类帧的子帧不同。例如，第一类帧为LTE系统中上行下行子帧配置为1 的LTE TDD 帧，则在同一个帧周期，即在10ms 中，第一类帧的第7个子帧为上行子帧，对应第二类帧的子帧为下行子帧，第一类帧的第8个子帧为上行子帧，对应第二类帧的子帧为特殊子帧，第一类帧的第9个子帧为下行子帧，对应第二类帧的子帧为上行子帧，第一类帧的第0个子帧为下行子帧，对应第二类帧的子帧为上行子帧，第一类帧的第1个子帧为特殊子帧，对应第二类帧的子帧为下行子帧，第一类帧的第2个子帧为上行子帧，对应第二类帧的子帧为下行子帧，第一类帧的第3个子帧为上行子帧，对应第二类帧的子帧为特殊子帧，第一类帧的第4个子帧为下行子帧，对应第二类帧的子帧为上行子帧，第一类帧的第5个子帧为下行子帧，对应第二类帧的子帧为上行子帧，第一类帧的第6个子帧为特殊子帧，对应第二类帧的子帧为下行子帧。其中，U表示上行子帧，D表示下行子帧，S表示特殊子帧。可见，第一类帧的第7子帧和第2子帧为上行子帧，且对应的第二子帧为下行子帧，第一类帧的第9子帧、第0子帧、第4子帧以及第5子帧为下行子帧，且对应的第二子帧为上行子帧，因此，可以将第一类帧的第7子帧、第9子帧、第0子帧、第2子帧、第4子帧以及第5子帧划分为传输子帧，其它子帧划分为接入子帧，同样的将第二类帧的第0子帧、第2子帧、第3子帧、第5子帧、第7子帧以及第8子帧划分为传输子帧，其它子帧划分为接入子帧，使得第一类帧的传输子帧的上行子帧对应第二类帧的传输子帧的下行子帧，而第一子帧的上行子帧对应第二类帧的下行子帧。
依此类推，当第一类帧为LTE系统中上行下行子帧配置为2或者其它子帧配置的LTE TDD帧时，同样可以确定第二类帧。
第一类帧的传输子帧和第二类帧的传输子帧用于第一通信设备与第二通信设备传输信息，第一类帧的接入子帧用于第一通信设备与对应的用户设备传输信息。具体地，第一类帧的传输子帧中的上行子帧用于接收第二通信设备发送的回传信息，第一类帧的传输子帧中的下行子帧用于向第二通信设备发送回传信息。第二类帧的传输子帧中的上行子帧用于接收第一通信设备发送的回传信息，第二类帧的传输子帧中的下行子帧用于向第一通信设备发送回传信息。如果第一通信设备是第一基站10，第二通信设备是第二基站20，则第二类帧的接入子帧用于第二基站20与对应的用户设备传输信息。
图3中，第一通信设备的第一类帧中的第7个子帧、第9个子帧、第0个子帧、第2个子帧、第4个子帧以及第5个子帧为传输子帧，第二通信设备的第二类帧中的第0个子帧、第2个子帧、第3个子帧、第5个子帧、第7个子帧以及第8个子帧为传输子帧，用于实现第一通信设备与第二通信设备之间传输信息。第一通信设备的第一类帧中的第8个子帧、第1个子帧、第3个子帧以及第6个子帧为接入子帧，用于第一通信设备与对应的用户设备传输信息，第二通信设备的第二类帧中的第1个子帧、第4个子帧、第6个子帧以及第9个子帧为接入子帧。第一通信设备的第一类帧中的第7个子帧表示第一类帧中的第7个子帧的上行子帧中接收第二通信设备发送的下行子帧。第一通信设备的第一类帧中的第2个子帧与此相同，不再赘述。第一通信设备的第一类帧中的第8个子帧表示第一类帧中的第8个子帧的上行子帧中接收第二通信设备发送的特殊子帧。第一通信设备的第一类帧中的第3个子帧与此相同。第一通信设备的第一类帧中的第9个子帧表示第一类帧中的第9个子帧的下行子帧中向第二通信设备发送上行子帧。第一通信设备的第一类帧中的第0个子帧、第4个子帧以及第5个子帧与此相同，不再赘述。第一通信设备的第一类帧中的第1个子帧表示第一通信设备向其对应的用户设备发送特殊子帧，同时第二通信设备向其对应的用户设备发送下行子帧。第一通信设备的第一类帧中的第6个子帧与此相同。如此，通过将第一类帧中的各子帧划分为传输子帧和接入子帧，第一类帧的接入子帧用于第一通信设备与用户设备传输信息，第一类帧的接入子帧用于第一通信设备与第二通信设备传输信息。从而实现对应子帧上的基带优化，保持了HARQ时序，将普通长期演进系统中 eNB之间可能存在的上下行干扰转化为互助传输，并利用长期演进系统中 eNB自身资源，实现无线方式的基站回传，大大降低了网络部署时间和成本。
如图4所示，第一类帧为LTE系统中上行下行子帧配置为2的LTE TDD帧，第二类帧为LTE系统中子帧配置为2的LTE TDD帧向前偏移3个子帧的帧。第一通信设备的第一类帧的第7子帧和第2子帧为上行子帧，且对应的第二子帧为下行子帧，第一类帧的第9子帧和第4子帧为下行子帧，且对应的第二子帧为上行子帧，因此，可以将第一类帧中的第7个子帧、第9个子帧、第2个子帧以及第4个子帧划分为传输子帧，对应的第二通信设备的第二类帧中的第0个子帧、第2个子帧、第5个子帧以及第7个子帧划分为传输子帧，这样第一类帧的传输子帧的上行子帧对应第二类帧的传输子帧的下行子帧，而第一子帧的上行子帧对应第二类帧的下行子帧，可以用于实现第一通信设备与第二通信设备之间传输信息。同时，第一通信设备的第一类帧中的第8个子帧、第1个子帧、第3个子帧、第5个子帧以及第6个子帧划分为接入子帧，第二通信设备的第二类帧中的第1个子帧、第3个子帧、第4个子帧、第8个子帧、第6个子帧、第8个子帧以及第9个子帧划分为接入子帧，用于第一通信设备和第二通信设备分别与对应的用户设备进行通信。第一通信设备的第一类帧中的第7个子帧表示第一类帧中的第7个子帧的上行子帧中接收第二通信设备发送的下行子帧。第一通信设备的第一类帧中的第2个子帧与此相同，不再赘述。第一通信设备的第一类帧中的第8个子帧表示第一通信设备向对应的用户设备发送下行子帧，同时第二通信设备向其对应的用户设备发送特殊子帧。第一通信设备的第一类帧中的第3个子帧与此相同。第一通信设备的第一类帧中的第9个子帧表示第一类帧中的第9个子帧的下行子帧中向第二通信设备发送上行子帧。第一通信设备的第一类帧中的第4个子帧与此相同。第一通信设备的第一类帧中的第0个子帧表示第一通信设备向其对应的用户设备发送下行子帧，同时第二通信设备向其对应的用户设备发送下行子帧。第一通信设备的第一类帧中的第5个子帧与此相同。第一通信设备的第一类帧中的第1个子帧表示向其对应的用户设备发送特殊子帧，同时第二通信设备向其对应的用户设备发送下行子帧。第一通信设备的第一类帧中的第6个子帧与此相同。
在本发明实施例中，第一通信设备生成第一类帧，并确定第一类帧中与第二类帧中的上行子帧对应的下行子帧，或者第一类帧中与第二类帧中的下行子帧对应的上行子帧为传输子帧，其中，第二类帧是由第二通信设备根据第一类帧进行子帧偏移后得到的，从而实现对应子帧上的基带优化，保持了HARQ时序，将普通长期演进系统中eNB之间可能存在的上下行干扰转化为互助传输。第一通信设备通过传输子帧与第二通信设备传输信息，从而利用长期演进系统中eNB自身资源，实现无线方式的基站回传，大大降低了网络部署时间和成本。
请参阅图5，图5是本发明第一实施例的LTE系统中通信设备的结构示意图。如图5所示，通信设备40包括电路元件41和天线元件42。电路元件41用于确定第一类帧中至少一个传输子帧，第一类帧由电路元件41生成，并且是长期演进系统中任一种子帧配置的时分双工帧，传输子帧为第一类帧中与第二类帧中的上行子帧对应的下行子帧，或者，第一类帧中与第二类帧中的下行子帧对应的上行子帧，其中，第二类帧是由另一通信设备根据第一类帧进行子帧偏移后得到的。天线元件42用于通过传输子帧与另一通信设备传输信息。

在本发明实施例中，电路元件还用于确定第一类帧中除传输子帧之外的其他子帧为接入子帧；天线元件还用于通过接入子帧与用户设备传输信息。而第二类帧中与第一类帧中的上行子帧对应的下行子帧，或者，第二类帧中与第一类帧中的下行子帧对应的上行子帧确定为传输子帧，第二类帧中除传输子帧之外的其他子帧确定为接入子帧。天线元件42通过第一类帧的传输子帧和第二类帧的传输子帧与另一通信设备传输信息，通过第一类帧的接入子帧与用户设备传输信息。具体地，天线元件42通过第一类帧的传输子帧中的上行子帧接收另一通信设备发送的回传信息，通过第一类帧的传输子帧中的下行子帧向另一通信设备发送回传信息。另一通信设备通过第二类帧的传输子帧中的上行子帧接收通信设备40发送的回传信息，通过第二类帧的传输子帧中的下行子帧向通信设备40发送回传信息。如果第一通信设备是第一基站10，另一通信设备是第二基站20，则第二基站20还通过第二类帧的接入子帧与用户设备传输信息。

请参阅图6，图6是本发明本发明第一实施例的LTE系统中基站回传的方法的流程示意图。如图6所示，基站回传的方法包括：
S10：第一通信设备40确定第一类帧中至少一个传输子帧，第一类帧由第一通信设备40生成，并且是LTE系统中任一种子帧配置的LTE时分双工TDD帧，传输子帧为第一类帧中与第二类帧中的上行子帧对应的下行子帧，或者，第一类帧中与第二类帧中的下行子帧对应的上行子帧，其中，第二类帧是由第二通信设备根据第一类帧进行子帧偏移后得到的。

S11：第一通信设备通过传输子帧与第二通信设备传输信息。
在本发明实施例中，第一类帧的传输子帧和第二类帧的传输子帧用于第一通信设备与第二通信设备传输信息。具体地，第一类帧的传输子帧和第二类帧的传输子帧形成第一通信设备与第二通信设备之间的无线回传信道。无线回传信道包括上行无线回传信道和下行无线回传信道。第一类帧的传输子帧中的上行子帧形成第一通信设备的上行无线回传信道，用于接收第二通信设备发送的回传信息，第一类帧的传输子帧中的下行子帧形成第一通信设备的下行无线回传信道，用于向第二通信设备发送回传信息。第二类帧的传输子帧中的上行子帧用于接收第一通信设备40以及MME/S-GW 30发送的回传信息，如果第一通信设备是第一基站10，第二通信设备是第二基站20，则第二类帧的接入子帧用于第二基站20与对应的用户设备之间的通信。
在本发明实施例中，通过第一通信设备40确定第一类帧中至少一个传输子帧，第一类帧由第一通信设备生成，并且是LTE系统中任一种子帧配置的LTE时分双工TDD帧，传输子帧为第一类帧中与第二类帧中的上行子帧对应的下行子帧，或者，第一类帧中与第二类帧中的下行子帧对应的上行子帧，其中，第二类帧是由第二通信设备根据第一类帧进行子帧偏移后得到的，从而实现对应子帧上的基带优化，保持了HARQ时序，将普通长期演进系统中 eNB之间可能存在的上下行干扰转化为互助传输，第一通信设备通过传输子帧与第二通信设备传输信息，从而利用长期演进系统中 eNB自身资源，实现无线方式的基站回传，大大降低了网络部署时间和成本。
