Description

一种协同调度的方法及基站
本申请要求于2016年9月29日提交中国专利局、申请号为201610863948.9、发明名称为“一种协同调度的方法及基站”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
本发明涉及通信领域，尤其涉及一种协同调度的方法及基站。
背景技术
随着移动通信技术的发展，用户对数据速率的要求越来越高，与此同时频谱资源紧缺的问题日益严重。为了满足LTE-Advanced(Long Term Evolution Advanced)***对带宽的需求而提出了载波聚合(CA，Carrier Aggregation)技术。与LTE***相比，LTE-Advanced***需要在上下行控制信道设计、功率控制等多方面做相应的改变以支持载波聚合的功能。
载波聚合在第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)定义的LTE(Long Term Evolution)标准中由无到有，持续增强。在Rel-10版本中，引入载波聚合技术，规定最多聚合5个成员载波，可以为用户在高速移动状态下提供100Mbit/s和低速移动状态下提供1Gbit/s的峰值速率，支持频段内连续载波聚合和频段间载波聚合。随着上行业务需求的进一步凸显，Rel-11版本对载波聚合技术进行增强，增加了更多的CA配置，对频段间的上行载波聚合技术进行研究和标准化。
在现有3GPP定义的LTE***可用频谱中，Band7(FDD)和Band38(TDD)这两个频谱，都属于2600M频段，且Band7和Band38这两个频谱紧挨，由于频谱间存在阻塞和杂散等干扰，3GPP LTE标准没有定义Band7和Band38的CA能力，当只有2600M频谱的Band7和Band38载波聚波时会存在严重的频谱干扰。在其他标准频段中，只有FDD和TDD频谱聚合时也会存在严重的频谱干扰。现有技术中，当只有同一标准频段的FDD频谱和TDD频谱聚合时，会产生严重的频谱干扰。
发明内容

结合本发明实施例的第二方面，在本发明实施例第二方面的第一种实现方式中，所述基站还包括：发送单元，用于向用户设备UE发送聚合指示消息，所述聚合指示消息用于指示所述主分量载波与所述辅分量载波完成聚合，以使得所述UE根据所述聚合指示消息配置信道质量指示CQI；接收单元，用于接收所述UE发送的聚合载波的CQI，当所述主分量载波处于CQI上报的上行子帧时，所述基站不调度辅分量载波对应的下行子帧；第二调度单元，当所述主分量载波处于下行调度时，用于根据所述CQI中的辅分量载波的CQI获取辅分量载波的信道质量，调度所述信道质量达到第一阈值的辅分量载波对应的下行子 帧。可以看出，追加了载波聚合完成后，UE配置CQI的过程，完善了该聚合过程的实施方式，增加了可实现性。

为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”或“具有”及其任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、***、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本发明实施例可应用于如图1所示的网络架构，在该网络架构中，E-UTRAN包括eNodeB和其它eNodeB，还可以包括多播协调实体(Multicast Coordination Entity，MCE)。eNodeB可以通过回程(backhaul)(例如X2接口)与其它eNodeB连接。MCE可以为eMBMS分配时频无线资源，并且为eMBMS确定无线配置(例如，MCS)。MCE可以是独立于eNodeB的实体，也可以是eNodeB的一部分。
eNodeB提供UE到EPC的接入，eNodeB连接到EPC。EPC可以包括MME，HSS，其它MME，SGW，MBMS GW，BM-SC，PGW。MME是处理UE和EPC之间信令的控制节点，提供承载和连接管理。所有用户IP包通过SGW进行发送，SGW与PGW进行连接。PGW提供UE IP地址分配以及其它功能。PGW和BM-SC连接到IP业务，IP业务可以包括Internet、intranet、IP Multimedia Subsystem(IMS)、PS Streaming Service(PSS)和/或其它IP业务。BM-SC可以为MBMS用户服务定位和传递的功能。BM-SC可以作为内容供应商MBMS传输的入口，可以在PLMN内用于授权和发起MBMS承载业务，也可以用于调度和传送MBMS传输。MBMS Gateway可以用作发布MBMS业务到属于一个广播特定业务的MBSFN区域的eNodeB，也可以用于回话管理(开始/停止)和收集eMBMS相关的计费信息。

本发明实施例中，基站确定TDD频段中第一预置带宽的频段作为主分量载波，确定FDD频段中第二预置带宽的频段作为辅分量载波；基站将主分量载波与辅分量载波聚合；当主分量载波处于下行调度时，基站调度辅分量载波对应的下行子帧。基站确保载波聚合后调度的辅分量载波的下行子帧与主分量载波的特殊子帧和上行子帧不冲突，避免只有同一标准频段的FDD频谱和TDD频谱聚合时产生的频谱干扰。
请参阅图2，本发明实施例中协同调度的方法一个实施例包括：
201、基站确定时分双工TDD频段中第一预置带宽的频段作为主分量载波。
基站根据预置的规则确定第一预置带宽的大小，基站在TDD频段中选择第一预置带宽大小的频段，将该频段作为主分量载波；基站确定TDD频段中主分量载波之外的频段为隔离频段，隔离频段用于抑制频谱间的干扰。
202、基站确定频分双工FDD频段中第二预置带宽的频段作为辅分量载波。
基站根据预置的规则确定第二预置带宽的大小，基站在FDD频段中选择第二预置带宽大小的频段，将该频段作为辅分量载波。辅分量载波与主分量载波属于同一标准频段，该标准频段可以是2600M标准频段，还可以是其他标准频段，如2100M标准频段，具体此处不做限定。
203、基站将主分量载波与辅分量载波聚合。
基站根据预置的规则，将确定的主分量载波和辅分量载波利用载波聚合技术聚合在一起。
204、当主分量载波处于下行调度时，基站调度辅分量载波对应的下行子帧。
基站根据业务需要，在主分量载波处于下行调度状态时，基站调度辅分量载波的下行子帧，且该下行子帧与主分量载波的下行子帧对应，与主分量载波的上行子帧和特殊子帧都不冲突。
基站确定TDD频段中第一预置带宽的频段作为主分量载波，确定FDD频段中第二预置带宽的频段作为辅分量载波，FDD频段与TDD频段属于同一标准频段；基站将主分量载波与辅分量载波聚合；当主分量载波处于下行调度时，基站调度辅分量载波对应的下行子帧。基站确保载波聚合后调度的辅分量载波的下行子帧与主分量载波的特殊子帧和上行子帧不冲突，避免只有同一标准频段的FDD频谱和TDD频谱聚合时产生的频谱干扰。
请参阅图3，本发明实施例中协同调度的方法另一个实施例包括：
301、基站确定时分双工TDD频段中第一预置带宽的频段作为主分量载波。
302、基站确定频分双工FDD频段中第二预置带宽的频段作为辅分量载波。
303、基站将主分量载波与辅分量载波聚合。
本实施例中的步骤301至303与前述图2所示实施例中的步骤201至203类似，具体此处不再赘述。
304、基站向用户设备UE发送聚合指示消息。
基站确定需要使用聚合的载波的UE，向该UE发送载波聚合完成的消息，使得UE根据 该聚合指示消息配置信道质量指示CQI信息，基站根据CQI信息为UE调度主分量载波和辅分量载波。
305、UE根据聚合指示消息配置CQI。
UE接收到基站发送的聚合指示消息，UE根据该消息配置聚合后的载波的CQI，当主分量载波处于CQI上报的上行子帧时，基站不调度辅分量载波对应的下行子帧。
306、基站接收UE发送的周期性主分量载波的CQI或非周期性主分量载波的CQI。
基站接收UE发送的CQI信息，该CQI信息根据基站发送的聚合指示消息生成，该CQI信息包括主分量载波的CQI，该主分量载波可以是周期性的载波或者非周期性的载波。
307、基站接收UE发送的周期性辅分量载波的CQI或非周期性辅分量载波的CQI。
基站接收UE发送的CQI信息，该CQI信息根据基站发送的聚合指示消息生成，该CQI信息包括辅分量载波的CQI，该辅分量载波可以是周期性的载波或者非周期性的载波。
308、当主分量载波处于下行调度时，基站根据接收到的CQI调度辅分量载波对应的下行子帧。
UE具备使用聚合载波业务的能力，当UE需要使用聚合后的载波时，基站根据接收到的CQI信息获取载波的信道质量，开始调度聚合后的载波。在调度主分量载波的基础上，当主分量载波处于下行调度时，基站调度信道质量达到第一阈值的辅分量载波对应的下行子帧。当主分量载波处于下行调度时，基站还调度主分量载波的信道质量达到第二阈值的主分量载波对应的下行子帧。
基站确定TDD频段中第一预置带宽的频段作为主分量载波，确定FDD频段中第二预置带宽的频段作为辅分量载波，FDD频段与TDD频段属于同一标准频段；基站将主分量载波与辅分量载波聚合；当主分量载波处于下行调度时，基站调度辅分量载波对应的下行子帧。基站确保载波聚合后调度的辅分量载波的下行子帧与主分量载波的特殊子帧和上行子帧不冲突，避免只有同一标准频段的FDD频谱和TDD频谱聚合时产生的频谱干扰。
为便于理解，下面结合具体的应用场景对本实施例进行描述：
不同国家对于频谱有不同的划分，下面以波兰的频谱划分标准为基础进行详细的说明。如图4所示，波兰将2600M的标准频段的频谱划分给三个不同的运营商，分别是运营商A、运营商B和运营商C，其中运营商A拥有band7(FDD)和band38(TDD)两种频谱，运营商B和运营商C在2600M的标准频段中只拥有band38(TDD)一种频谱。运营商A拥有band7(FDD)和band38(TDD)两种频谱，所以该运营商A可以将两种频谱进行聚合。
运营商A将拥有TDD频谱50M和FDD频谱上下行各20M，当用户设备UE需要使用载波聚合业务功能时，此时，运营商A的基站K将TDD频谱中的40M大小的频谱确定为主分量载波，基站K将FDD频谱中的上下行各20M大小的频谱确定为辅分量载波，基站K将剩余的10M大小的TDD频谱确定为隔离频段，用于减少频谱间的干扰。主分量载波和辅分量载波的大小可以根据运营商的实际需要预先设置好。
基站K将主分量载波和辅分量载波聚合在一起；基站K向UE发送载波聚合完成的聚合指示消息，UE收到该聚合指示消息后，开始配置CQI信息，该CQI信息包括周期性的主分量载波的CQI和周期性的辅分量载波的CQI，基站K根据接收到的CQI信息对辅分量载波 进行调度；
当主分量载波处于下行调度时，基站K调度信道质量达到第一阈值的辅分量载波的下行子帧，且调用的该辅分量载波的下行子帧与主分量载波的上行子帧和特殊子帧都不冲突。换句话说，当主分量载波处于下行调度时，基站K只调用辅分量载波中与主分量载波下行子帧对应的部分下行子帧。当主分量载波处于下行调度时，基站K可以调度辅分量载波的上行子帧，不能调度辅分量的下行子帧。基站K将调度信息发送给UE，UE可以使用基站K调度的频谱进行网络服务。
上面对本发明实施例中协同调度的方法进行了描述，下面对本发明实施例中的基站进行描述，请参阅图5，本发明实施例中的基站包括：

第一调度单元504，当主分量载波处于下行调度时，用于调度辅分量载波对应的下行子帧。
