支持eMBMS的方法、MCE、基站和终端 技术领域
本发明实施例涉及通信领域，尤其涉及支持eMBMS(Evolved Multimedia Broadcast Multicast Service，增强型多媒体广播多播业务)的方法、MCE(Multi-cell/multicast CoordinationEntity，多小区多播协作实体)、基站和终端。
背景技术
MBMS(Multimedia BroadcastMulticast Service，多媒体广播多播业务)是3GPP(The3rd Generation Partnership Project，第三代合作伙伴计划)提出的基于移动通信系统的多媒体业务。3GPP的LTE(Long Term Evolution，长期演进)系统支持eMBMS，以支持更高品质的流媒体和及时性广播服务。
LTE定义了1.4MHz、3MHz、5MHz、10MHz、15MHz和20MHz的标准带宽。在网络实际应用中，存在非标准带宽的需求，比如只有8MHz、9MHz或19MHz的非标准带宽。
当前的3GPP协议中eMBMS没有调度机制，演进基站(evolved NodeB，eNB)和终端(User Equipment，UE)只能按照小区系统消息中的标准带宽对承载eMBMS数据的资源进行调制和解调，因此，非标准带宽小区无法支持eMBMS，限制了eMBMS的应用范围。
发明内容
本发明实施例提供了一种支持eMBMS业务的方法、MCE、基站和终端，可以通过配置可用带宽信息，使基站能够对承载eMBMS数据的资源按照实际可用带宽进行调制以及终端按照实际可用带宽解调资源，从而使得非标准 带宽小区能够支持eMBMS，扩展了eMBMS的应用范围。
第一方面，本发明实施例提供了一种支持eMBMS的方法，该方法包括：配置可用带宽信息；将可用带宽信息发送给基站，以使基站将可用带宽信息发送给终端以及按照可用带宽信息对资源进行调制。
本发明实施例提供的支持eMBMS的方法可以使基站按照可用带宽信息对承载eMBMS数据的资源进行调制，使得非标准带宽小区也具有支持eMBMS的功能，扩大了eMBMS的应用范围。
第二方面，本发明实施例提供了另一种支持eMBMS的方法，该方法包括：接收可用带宽信息，或者配置可用带宽信息；将可用带宽信息发送给终端；根据可用带宽信息对资源进行调制；将根据可用带宽信息进行调制后的资源发送给终端。
本发明实施例提供的支持eMBMS的方法可以接收或配置可用带宽信息，并按照可用带宽信息对承载eMBMS数据的资源进行调制，已将将调制后的资源发送给终端，使得非标准带宽小区也具有支持eMBMS的功能，扩大了eMBMS的应用范围。
第三方面，本发明实施例提供了又一种支持eMBMS的方法，该方法包括：接收可用带宽信息，以及根据实际可用带宽进行调制后的资源；根据可用带宽信息对所述资源进行解调。
本发明实施例提供的支持eMBMS的方法可以接收可用带宽信息以及根据该可用带宽信息进行调制的资源，然后，可以根据可用带宽信息对该资源进行解调，从而使得非标准带宽小区也具有支持eMBMS的功能，扩大了eMBMS的应用范围。

具体实施方式
本发明实施例涉及支持eMBMS的方法、MCE、基站和终端，MCE可以配置可用带宽信息，并发送给基站。基站可以接收MCE发送的可用带宽信息后，也可以配置可用带宽信息，并且可以将可用带宽信息发送给终端；基站根据可用带宽信息对资源进行调制，并将调制后的资源发送给终端；终端接收可用带宽信息以及调制后的资源后，可以根据可用带宽信息解调资源，以获取资源信息。
本发明实施例提供的支持eMBMS的方法、MCE、基站和终端可以按照可用带宽信息对承载eMBMS数据的资源进行解调和调制，使得非标准带宽小区也具有支持eMBMS的功能，扩大了eMBMS的应用范围。
下文对本发明实施例涉及到的非标准带宽进行介绍。
LTE定义了1.4MHz、3MHz、5MHz、10MHz、15MHz和20MHz的标准带宽。对于非标准带宽，可以通过减少标准带宽的有效带宽的方式来实现，可以既充分利用频率资源、而又不影响现有终端。
减少有效带宽的技术是把实际可用带宽配置成标准带宽使用，把标准带宽进行一些限制和压缩处理，让标准带宽中传输数据的带宽在实际可用带宽范围内。这种方案适用的范围更广。
如表1所示，不同的带宽容纳不同的RB(Resource Block，资源块)数。减少标准带宽有效带宽的方法包括压缩RB数和信道特殊处理。以实现8MHz的非标准带宽为例，基站可以通过压缩10个RB，将容纳50个RB的10MHz的标准带宽压缩到40个RB以实现8MHz的非标准带宽。
表1 带宽及其可容纳RB数
带宽(MHz) 1.4 3 5 8 9 10 15 19 20
可容纳RB数 6 15 25 40 46 50 75 98 100
压缩RB对终端透明。在通过压缩标准带宽以得到的非标准带宽下，为了降低压缩RB产生的性能损失，基站将对相关物理信道的资源管理算法进行调整，保证不在压缩的RB位置分配资源。相关的物理信道如下文所述。
上行物理信道：
PRACH(Physical Random Access Channel，物理随机接入信道)：PRACH占用6个RB，与PUCCH在频域相邻，对PRACH无影响。
PUCCH(Physical Uplink Control CHannel，物理上行链路控制信道)：通过配置码道号和CQI(Channel Quality Indicator，信道质量指示)占用RB使得两端压缩的RB空出，PUCCH资源向频带中心移动。
PUSCH(Physical Uplink Shared Channel，物理上行共享信道)通过调度保证分配资源不占用压缩的RB。
SRS(Sounding Reference Signal，信道探测参考信号)只使用可用的RB，资源分配方式不变。
下行物理信道：
PCFICH(Physical Control Format Indicator Channel，物理控制格式指示信道)，限制PCI(Protocol Control Information，协议控制信息)的分配保证PCFICH不占用压缩的RB上的子载波。
PHICH(Physical Hybrid ARQ Indicator Channel，物理混合自动重传指示信道)限制PCI分配和PHICH的Ng参数，保证PHICH不占用压缩的RB上的子载波。
PDCCH：physical downlink control channel,物理下行控制信道，某些UE的CCE，Control Channel Element控制信道单元，会映射到压缩RB上，需要提高PDCCH解调性能。
PDSCH：Physical Downlink Shared Channel--物理下行共享信道，需要限制不调度压缩带宽上的RB资源。
下文对本发明实施例涉及到的eMBMS相关概念进行介绍。
eMBMS采用点到多点单向下行方式，在基站下的小区分配一份可共享的广播业务承载资源，可同时给多个终端提供业务传输。eMBMS的特性是采用多小区联合广播，点对多点传输方式，通过公共的广播信道传送控制面和用户面的数据，小区下对于同一个eMBMS业务感兴趣的终端，可以在相同的无线资源上接收和共享同一份eMBMS业务数据。具备eMBMS业务接收能力的终端，支持在连接态或空闲态进行eMBMS业务数据的接收，且eMBMS业务的接收不应受终端是否同时进行单播业务影响。不具备eMBMS业务接收能力的终端，需要根据SIB2(System Information Block Type 2，系统消息块2)消息内容识别MBSFN子帧配置信息，在下行测量中避开MBSFN(MBMS Single Frequency Network，MBMS单频点组网)子帧。
一个MBSFN同步区里的小区对应相同的频点；一个基站中相同频点的小区对应一个MBSFN同步区。一个MBSFN同步区下可以存在多个MA(MBSFN Area，MBMS单频点组网区域)。一个MA下面有MBSFN小区和MA保留 小区两种小区。一个MA下面的所有MBSFN小区和MA保留小区应具有完全一致的MBSFN无线资源分配策略。一个小区可以属于多个MA，即MA可以重叠。MA与MBMS服务区之间是独立的，没有必然联系。但为了资源利用最大化和业务规划维护便利性，在MBMS业务规划时，要求在一个MBMS服务区下规划一个或多个完整的MA。
下文结合图1对本发明实施例涉及到的eMBMS的系统框架进行介绍。
如图1所示，eMBMS相关的网络结构可以包括BM-SC(Broadcast Multicast Service Centre，广播多播服务中心)、MBMS GW(MBMS GateWay，MBMS网关)、MME(Mobility Management Entity，移动管理实体)、MCE、基站(例如，演进型基站或其他类型的基站)。BM-SC负责提供eMBMS业务和发起eMBMS承载建立过程，并与MBMS GW实现相应功能。MBMS GW一方面采用IP多播的方式向基站传输用户平面数据，另一方面和MME交互eMBMS会话控制信令。MME根据从MBMS GW收到的eMBMS会话控制信令与MCE通信实现MBMS会话的控制，如MBMS业务的开始和停止。MCE负责MBSFN区域中基站发送eMBMS的无线资源的分配。MCE既可以作为一个实体独立存在，也可以集成在基站中。
下文结合图2对本发明实施例涉及到的eMBMS的空中接口信道进行介绍。
如图2所示，eMBMS空中接口信道包括MCCH(Multicast Common Control Channel，多播公共控制信道)、MTCH(Multicast Traffic Control Channel、MCH(Multicast Channel，多播信道)、PMCH(Physical Multicast Channel，物理多播信道)。
MCCH和MTCH是eMBMS的逻辑信道。MCCH信道用于向处于空闲态或连接态的终端传送下行点对多点的控制面信息。一个MA下只存在一个MCCH，用于传递该MA下的无线资源配置(例如：PMCH配置、MTCH配置等)信息。MCCH映射在MCH上进行传输，在空中接口，基站可以通过 SIB13(System Information Block Type 13，系统信息块13)通知终端当前小区下是否配置了MCCH信道。MCCH信道可以和MTCH信道复用在同一个MCH上进行传输。
MTCH信道用于向处于空闲态或连接态的终端传送下行点对多点的用户面信息。MTCH映射在由MCCH指定的MCH上进行传输。多个MTCH可以被映射到同一个MCH上进行传输。
另外，MTCH可以与MCCH映射在同一个MCH上进行传输，此时MTCH使用的MCS由MCCH使用的MCS(Modulation and Coding Scheme，调制与编码策略)决定。需要说明的是，MTCH和MCCH使用的MCS可根据需要单独静态配置。由于MCCH会携带有MTCH的配置信息，因此，为了保证MCCH的正确解调，优选地，MCCH使用的MCS要低于或等于MTCH使用的MCS。
MCH是eMBMS的传输信道，其在空中接口上映射在PMCH上进行传输，MCH无HARQ(Hybrid Automatic Repeat Request，混合自动重传请求)机制。MCH与PMCH一一对应。单个MA下的多个eMBMS业务可以被映射在同一个MCH上传输。
PMCH：是eMBMS的物理信道，其用于承载传输信道MCH，其由一个或多个MBSFN子帧传输。对于eMBMS业务传输而言，同一个MA下的多个小区在PMCH上传输相同的内容，由终端在接收时进行合并。MCE通过配置决定单个PMCH由多少个MBSFN子帧进行传输及MBSFN子帧调度的具体位置。基站将PMCH配置信息通过MCCH消息通知终端。
下文结合图3对本发明实施例涉及到的MBSFN子帧进行介绍。
在一个示例中，eMBMS的特性可以遵循3GPP TS 36.213协议内容，采用混合子帧传输方式实现，即MBSFN子帧与普通子帧在时域上采用时分分配方式混合传输。FDD(Frequency Division Duplexing，频分双工)的MBSFN子帧与普通子帧混合方式如图3a所示，子帧0/4/5/9固定为普通子帧，子帧 1/2/3/6/7/8可以配置为MBSFN子帧，即一个子帧最多可配置6个MBSFN子帧用以传输eMBMS业务。
如图3b所示，单个MBSFN子帧由非MBSFN区域和MBSFN区域组成，非MBSFN区域中仍可以传输PDCCH信息。
MBSFN子帧特点如下。
MBSFN子帧的小区参考信号(详情可参见3GPP TS 36.211V10.7.0中6.10.2"MBSFN reference signals"节描述)固定在天线端口4发送。MBSFN子帧中的符号，可以划分为非MBSFN区域和MBSFN区域。其中，非MBSFN区域可配置1～2个符号，除去非MBSFN区域外，剩下的符号为MBSFN区域。
eMBMS特性相关的无线资源均以MA为单位进行配置，即单个MA下所有小区的无线资源配置需保持一致，由MCE统一进行调度。无线资源配置的最小单位为MBSFN子帧，其配置信息通过系统消息广播给终端，终端根据收到的配置信息到对应的无线资源上获取对应的eMBMS业务内容。
在一个示例中，单个MA的资源配置信息内容和广播方法如下。
MA的基站可以根据MCE下发的无线资源配置，可以将当前MA下MBMS业务对应的无线资源调度情况携带在SIB13中进行广播。无线资源调度情况具体可以包括：MA配置信息列表(由SIB13中的MBSFN-AreaInfoList信元承载)和MBMS业务通知配置(由SIB13中的MBMS-NotificationConfig信元承载)。
终端通过接收SIB13，确定MA的MCCH发送的以及MCCH变更通知占用的无线资源的位置，以获取MCCH消息。然后，终端基于获取的MCCH消息，获取MBMS业务相关无线资源调度信息，包括公共子帧分配和PMCH配置。
下文结合图4对本发明实施例提供的支持eMBMS的方法进行介绍，该方法的执行主体为MCE。
401、配置可用带宽信息；
MCE负责MBSFN区域中基站发送eMBMS的无线资源的分配，可以在MCE中配置实际可用的带宽信息。MCE可以作为一个实体独立存在，也可以集成在基站中。
402、将所述可用带宽信息发送给基站，以使所述基站将所述可用带宽信息发送给终端以及按照所述可用带宽信息对资源进行调制。
MCE可以将可用带宽信息发送给基站，基站获取可用带宽信息后，将可用带宽信息发送给终端，使得终端能够根据可用带宽信息解调承载有eMBMS数据的资源。基站还可以根据可用带宽信息对承载有eMBMS数据的资源进行调制，以用于后续的资源发送。
本发明实施例提供的支持eMBMS的方法，通过MCE配置可用带宽信息，使得基站能够根据可用带宽信息进行资源调制，以及终端能够根据可用带宽信息进行资源解调，从而使得非标准带宽的小区也能够支持eMBMS，扩大了eMBMS的应用范围。
在一个示例中，可用带宽信息包括实际可用RB数。在MCE可以配置实际可用RB数，并将实际可用RB数发送给基站。基站可以根据实际可用RB数对资源进行调制。基站可以将实际可用RB数发送给终端，使得终端能够解调MBSFN子帧中下行实际可用的RB。
在一示例中，可用带宽信息包括标准带宽的压缩系数。在MCE可以配置标准带宽的压缩系数，并将标准带宽的压缩系数发送给基站。基站可以根据标准带宽的压缩系数获得非标准带宽信息，进而可以根据非标准带宽信息进行资源调制。基站可以将标准带宽的压缩系数发送给终端，使得终端能够根据标准带宽的压缩系数获得非标准带宽的信息，进而可以根据非标准带宽信息进行资源解调。

在一个示例中，上述可用带宽信息可以包括实际可用RB数或标准带宽压缩系数。
在一个示例中，上述可用带宽信息可以通过空口消息进行发送，空口消息包括SIB13。本发明实施例提供的支持eMBMS的方法可以通过SIB13扩展增加MBSFN子帧的下行可用带宽信息。

在另一个例子中，可以将标准带宽的压缩系数携带在SIB13中，可以在SIB13的bandWidthReduceFactor信元上承载标准带宽的压缩系数，例如0.9、0.8、0.7、0.6。以10M标准带宽为例，10MHz标准带宽可容纳50个RB数， 如果压缩系数为0.8，则表明将10MHz带宽压缩为8MHz非标准带宽，8MHz非标准带宽可容纳40个RB数。具体配置如下：
