移动通信网络通常采用蜂窝系统，即在不同的地点架设不同的基站，每个基站形成一个小区，负责该地方的移动用户的通信。一般的移动通信网络中，存在一些通信业务量较大的热点地区。为实现对热点地区提供较高的系统容量，通常在热点地区架设微小区，通过微小区对热点地区的移动用户提供业务。
因此，移动通信网络通常为多层小区结构（Heterogeneous Network，Het Net）。首先使用宏基站创建宏小区实现大范围的连续网络覆盖，然后在热点地区使用微基站创建微小区进行重叠覆盖，微小区提供较高的系统容量。
系统信息广播（System Information Broadcase）是通信系统中的一个重要功能，主要提供了接入网系统的主要信息，以便于用户设备（User Equipment，UE）建立无线连接。系统信息广播中的系统信息是连接UE和网络的纽带，UE演进的通用陆基无线接入网之间通过系统信息的传递，完成无线通信各类业务和物理过程。
在很多技术中，广播消息具有很强的地域性，如小小区发现过程中，很多时候需要系统信息提供邻区的小小区信息，如物理小区标识，频率信息，参考信令信息，而设备对设备（Device-to-Device，D2D）通信用户设备，需要判断在其附近区域是否有可用的资源存在等等。
现有的广播消息的方法，为了节省无线资源，通常向小区中所有UE广播相同的系统信息，因此无法减少随着新技术需求产生的系统信息。另外，用户设备也有可能因此接收到与自己无关的消息，从而触发不必要的行为。

【具体实施方式】
基于现有技术存在的不足，本发明实施例提供一种广播消息的方法及基站、用户设备，旨在解决如何针对用户设备群需求广播针对用户设备群的系统信息的技术问题，从而有效减少随着新技术需求产生的系统信息，并避免用户设备接收到与自己无关的消息触发不必要的行为。
以下结合附图和具体实施例，对本发明的技术方案进行详细阐述：
请参阅图1，图1是本发明实施例提供的第一种广播消息的方法的流程图，本实施例的广播消息的方法以基站的角度来进行描述，本实施例的广播消息的方法包括：
S101：基站确定第一小区下的系统信息的至少一个系统子组信息；
每个系统子组信息包括应用在与系统子组信息对应的用户设备群组的系统信息内容。具体地，每个用户设备群组对应的系统子组信息包括用户设备群组所在区域相邻的小小区信息、用于设备对设备通信连接的无线资源信息的至少一种。其中，第一小区是指基站控制的一个小区，用户设备群组是第一小区下的至少一个用户设备组成的群体。
比如用户设备群组1的系统子组信息可以包括用户设备群组1所在区域相邻的小小区信息，而小小区信息可以包括物理小区标识（Physical Cell Identifier，PCI）、频率信息、专用参考信号信息、信道状态信息参考信号信息、公共的物理配置以及系统信息块（System Information Block，SIB）信息中的至少一种。用户设备群组1的系统子组信息还可以包括可用的用于设备对设备（Device to Device，D2D）通信连接的无线资源信息，而无线资源信息可以包括分配的资源、位置信息以及干扰水平中的至少一种。
每个用户设备群组对应的的系统子组信息通过增强下行物理控制信道（Physical Downlink Shared Channel，PDSCH），或增强下行物理控制信道和增益下行控制信道Enhanced Downlink Control Channels，EPDCCH）进行区分。比如，不同用户设备群组对应的系统子组信息使用的不同的PDSCH资源，同时不同的系统子组信息使用的下行控制信道（Downlink Control Channels， PDCCH）资源相同;或者不同的系统子组信息使用的不同的EPDCCH资源；或者不同的系统子组信息使用的不同的PDSCH资源，同时不同的系统子组信息使用不同的码资源对PDCCH进行加扰。
更进一步地，系统子组信息中还可以包括指示系统子组对应的标识或者标号或者子组指示。系统子组信息的标识或标号用于标识不同的系统子组信息，子组指示用于指示系统子组信息、用户设备群组与用户设备群组所在区域的对应关系。
基站确定第一小区下的系统信息的至少一个系统子组信息的步骤可以是通过配置解调参考信号、扰码序列索引、天线端口以及预编码（Precoding）中的至少一种参数来实现。其中预编码可以是利用小区参考信号（Cell-specific Reference Signals，CRS）预定义的预编码。比如通过precoding1(P1)来编码的波束1来广播系统子组信息1，通过precoding2,3(P2,3)来编码的波束2、3分别广播系统子组信息2、3。其中，波束1的波束宽度和波束指向可以覆盖用户设备群组1所在区域，波束2、3的波束宽度和波束指向分别可以覆盖用户设备群组2、3所在区域。
其中，这些参数的配置可以是静态的，也可以是半静态的。比如可以根据用户设备群组所在区域的处于连接态UE上报的参考信号接收功率/参考信号接收质量，或者是对信道状态信息（Channel Status Information，CSI）上报取个长周期的平滑值，如平均值或加权平均值。
S102：向用户设备群组广播用户设备群组对应的系统子组信息；
基站向用户设备群组广播用户设备群组对应的系统子组信息。比如基站向用户设备群组1的用户设备广播系统子组信息1，向用户设备群组2、3分别广播系统子组信息2、3，其中，系统子组信息1包括应用在用户设备群组1的系统信息内容，系统子组信息2、3包括应用在用户设备群组2、3的系统信息内容。
本实施例中具体实现基站向用户设备群组广播该用户设备群组对应的系统子组信息的实现方式，可以包括：
1、通过每个用户设备群组所在区域对应的波束来实现向用户设备群组的用户设备广播用户设备群组对应的系统子组信息。
比如通过波束1来广播系统子组信息1，通过波束2、3分别广播系统子组信息2、3。其中，波束1的波束宽度和波束指向可以覆盖用户设备群组1所在区域，波束2、3的波束宽度和波束指向分别可以覆盖用户设备群组2、3所在区域。
2、通过每个用户设备群组所在区域对应的系统信息无线网络临时标识（SI-RNTI）向每个用户设备群组的用户设备广播每个用户设备群组对应的系统子组信息，每个用户设备群组对应的系统子组信息分别对应不同的系统信息无线网络临时标识。
比如通过SI-RNTI-1来加扰广播系统子组信息1的信息，通过SI-RNTI-2来加扰广播系统子组信息2的消息。系统子组信息1对应的用户设备群组中的UE通过事先获得的SI-RNTI-1来解扰广播系统信息，从而获得广播系统子组信息1的信息；系统子组信息2对应的用户设备群组中的UE通过事先获得的SI-RNTI-2来解扰广播系统信息，从而获得广播系统子组信息2的信息。
当然，在可以实现本发明实施例目的的情况下，本领域技术人员也可以通过其他的实现方式来向每个用户设备群组的用户设备广播每个用户设备群组对应的系统子组信息。
用户设备在接收到其所在用户设备群组的系统子组信息后，可以执行以下操作：
当用户设备为第一小区（例如宏小区）用户设备时，其可以根据系统子组信息来判断是否去触发异频小区发现和测量。其中，第一小区是基站控制下的广播系统消息的服务小区。比如当用户设备发现系统子组信息里指示有异频的相邻小小区（small cell），则触发异频测量；如果系统子组信息里没有指示存在异频的相邻小小区，则不触发异频测量。
当用户设备为D2D用户设备时，用户设备可以根据系统子组信息来判断是否有可用的D2D资源存在。
当用户设备为支持新载波类型（New Carrier Type，NCT）的用户设备，用户设备可以根据系统子组信息从宏小区获取同覆盖的NCT系统信息。
通过上述实施例的描述，可以理解，本实施例提供的广播消息的方法，基站确定第一小区下的系统信息的至少一个系统子组信息，该每个系统子组信息包括应用在与系统子组信息对应的用户设备群组的系统信息内容，向用户设备群组广播用户设备群组对应的系统子组信息。通过这样的方式，使系统信息广播更加具有针对性，用户设备只接收跟自己有关的系统子组信息，不会因此而触发不必要的行为。
请参阅图2，图2是本发明实施例提供的第二种广播消息的方法的流程图，本实施例的广播消息的方法以基站的角度来进行描述，本实施例的广播消息的方法包括以下步骤：
S201：基站将用户设备群组划分为不同的区域；
基站可以预先将其控制范围的用户设备群组划分为不同的区域。
具体实现时，区域之间的分界线可以由宏基站根据邻区关系的聚集情况来界定，如某个区域的小小区较密集部署，可以在那里形成一个区域，该区域内的用户设备群组划分到该区域。
又或者，区域之间的分界线可以由用户设备的数量来决定。如当某区域的用户设备的数量较多时，可以将该分界线向里设置，即将区域设置得小一些，当用户设备的数量较小时，可以将该分界线向外设置，即将区域设置得更大一些，以容纳更多的用户设备。具体的用户设备的数量可以根据实际情况而设定，不同的用户设备群组对应的区域在宏小区内可以是连续覆盖，也可以是离散覆盖的。
其中，区域的划分可以是静态的，也可以是半静态的。比如用户设备A固定划分到区域1，或者用户设备A第一时间段划分到区域1，第二时间段划分到区域2或区域3等等。其中，第一时间段与第二时间段的时间间隔为预先设定的某个值，比如1个月、3个月或者1年等等。
当用户设备群组所在区域发生变化时，如果是通过波束向用户设备群组的用户设备发送该用户设备群组对应的系统子组信息，可以通过调整高定向性天线的波束宽度和波束指向即可实现通过波束对改变后的区域发送系统子组信息。
其中，本实施例的广播消息的方法还包括：将用户设备划分为不同的用户设备群组。
将用户设备划分为不同的用户设备群组可以通过以下方式来实现：比如将第一小区下的不同的区域的用户设备分别划分为不同的用户设备群组；或将第一小区下的不同种类的用户设备分别划分为不同的用户设备群组；或将第一小区下的运行不同业务类型的用户设备分别划分为不同的用户设备群组。
当然，以上用户设备的划分只是一种示意性的，在可以实现本发明目的的前提下，用户设备划分为不同的用户设备群组的实现也可以是其他方式。
S202：基站广播公共系统信息；
公共系统信息可提供映射信息在不同的系统子组信息对应的配置信息和辅助的识别指纹信息（Fingerprint Information）。其中，系统子组信息对应的配置信息如天线端口数或预编码信息。辅助的识别指纹信息可以是定位信息，也可以是1-3个相邻的和/或同覆盖的小区的信息（如频率、PCI、参考信号接收功率/参考信号接收质量等）。
其中，公共系统信息还可以进一步包括系统子组信息的标识或标号。
S203：基站确定第一小区下的系统信息的至少一个系统子组信息；
每个系统子组信息包括应用在与系统子组信息对应的用户设备群组的系统信息内容。具体地，每个用户设备群组对应的系统子组信息包括用户设备群组所在区域相邻的小小区信息、用于设备对设备通信连接的无线资源信息的至少一种。其中，第一小区是指基站控制的一个小区，用户设备群组是第一小区下的至少一个用户设备组成的群体。
比如用户设备群组1的系统子组信息可以包括用户设备群组1所在区域相邻的小小区信息，而小小区信息具体可以包括PCI、频率信息、专用参考信号信息、信道状态信息参考信号信息、公共的物理配置以及SIB信息中的至少一种。用户设备群组1的系统子组信息还可以包括可用的用于D2D通信连接的无线资源信息，而无线资源信息可以包括分配的资源、位置信息以及干扰水平中的至少一种。
每个用户设备群组对应的系统子组信息通过PDSCH，或PDSCH和EPDCCH进行区分。比如，不同用户设备群组对应的系统子组信息使用的不同的PDSCH资源，同时不同的系统子组信息使用的PDCCH资源相同;或者不同的系统子组信息使用的不同的EPDCCH资源；或者不同的系统子组信息使用的不同的PDSCH资源，同时不同的系统子组信息使用不同的码资源对PDCCH进行加扰。
更进一步地，系统子组信息中还可以包括指示系统子组对应的标识或者标号或者子组指示。系统子组对应的标识或标号用于标识不同的系统子组信息，子组指示用于指示系统子组信息、用户设备群组与用户设备群组所在区域的对应关系。
基站确定第一小区下的系统信息的至少一个系统子组信息的步骤可以是通过配置解调参考信号、扰码序列索引、天线端口以及预编码中的至少一种参数来实现。其中预编码可以是利用CRS预定义的预编码。
其中，这些参数的配置可以是静态的，也可以是半静态的。比如可以根据用户设备群组所在区域的处于连接态UE上报的参考信号接收功率/参考信号接收质量，或者是对CSI上报取个长周期的平滑值，如平均值或加权平均值。
S204：对每个用户设备群组对应的系统子组信息进行多用户多入多出预编码；
在通过高定向性天线形成的波束来广播系统子组信息时，多个不同的用户设备群组对应的系统子组信息之间可能存在干扰，因此，在利用波束进行系统子组信息广播之前，可以先对每个用户设备群组对应的系统子组信息进行多用户多入多出（Multiple User-Multiple Input Multiple Output，MU-MIMO）预编码，在预编码完成后，再通过波束广播经预编码后的系统子组信息。
S205：通过每个用户设备群组所在区域对应的波束向用户设备群组广播每个用户设备群组对应的进行多入多出预编码后的系统子组信息；
在通过波束广播进行多入多出预编码后的系统子组信息之前，基站根据每个用户设备群组所在区域的位置信息设置高定向性天线的波束宽度和波束指向，以使得高定向性天线形成的波束能够覆盖其对应的区域。
具体地，基站获取用户设备群组所在区域的位置信息，然后根据该区域的位置信息，使用波束成性算法来来设置高定向性天线的波速宽度和波束指向。其中，不同热点地区对应的高定向性天线的波束宽度和波束执行是不同的。与波束宽度和波束指向对应的波束可以覆盖该区域。其中，位置信息可以是以下至少一个区域的面积、形状、方位角等。
其中，基站可以利用高定向性天线形成的至少两个波束对至少两个区域形成覆盖。
高定向性天线形成的波束中提供用户设备群组所在区域的系统子组信息对应的公共控制信道、业务信道等多个物理信道。
另外，更进一步的，可以根据需要某个系统子组信息的区域的数量来灵活设置高定向性天线的数量。若需要进行广播的区域的数量较少，基站可以根据区域的位置信息设置一个高定向性天线的数量。
比如若数量较少，基站可以根据区域的位置信息设置一个高定向性天线的波束宽度和波束指向，利用该高定向性天线为需要某个系统子组信息的所有区域提供系统子组信息。
若数量较多，基站可以根据位置信息设置高定向性天线的波束宽度和波束指向，不同的高定向性天线分别为不同的区域提供对应的系统子组信息，可以在多个高定向性天线之间灵活分配资源。举例来说，在一个实施例中如果区域数为4个，那么可以根据这4个区域的位置信息设置两个高定向性天线的波束宽度和波束指向，使每个高定向性天线分别为两个区域提供系统子组信息。比如可以参见图3，图3是本发明实施例提供的阵列天线的示意图。
高定向性天线可以为阵列天线，当然还可以为其它类型的天线，例如在信号频率较高时，例如微波频段，则高定向性天线可以为抛物面天线。当采用线性阵列时，由于在垂直方向上没有形成波束，则可以形成扇形微小区。当采用平面阵列时，可以是32阵元的8×4均匀平面阵列，则可以在水平和垂直两个方向同时形成较窄的波束，即3D波束成型，也就是同时在水平和垂直方案形成波束，从而可以更好地生成区域覆盖。另外，还可以是圆形阵列和三维网格阵列天线也能实现3D波束成型。
利用高定向性天线形成的波束向多个用户设备群组的用户设备分别广播对应的预编码后的系统子组信息。本实施例中，通过预先设置合适的预编码向量，可以消除不同的多个用户设备群组的系统子组信息之间的干扰，可以进一步提高通行系统容量。
用户设备可以通过公共系统信息中获取的预编码信息，对应接收用户设备群组所在区域对应的预编码的系统子组信息，并根据系统子组信息执行后续操作。
比如当用户设备为第一小区（比如宏小区）用户设备时，用户设备可以根据系统信子组信息来判断是否去触发异频小区发现和测量。
当用户设备为D2D用户设备时，用户设备可以根据系统子组信息来判断是否有可用的D2D资源存在。
当用户设备为支持新载波类型（New Carrier Type，NCT）的用户设备，可以根据系统子组信息从宏小区获取同覆盖的NCT系统信息。
请参阅图4，图4是本发明实施例提供的第三种广播消息的方法的流程图，本实施例以用户设备的角度来进行描述，本实施例的广播消息的方法包括：
S301：用户设备获取用户设备所在用户设备群组对应的系统子组信息相关的配置信息；
基站向每个用户设备群组的用户设备广播用户设备群组对应的系统子组信息。用户设备需要预先获取用户设备所在用户设备群组对应的系统子组信息相关的配置信息，以用于接收对应的系统子组信息。
其中，处于连接态的用户设备可以通过专用信息获得用户设备所在用户设备群组对应的系统子组信息相关的配置信息。处于空闲态的用户设备可以通过和网络临时交互过程中的消息来获取用户设备所在用户设备群组对应的系统子组信息相关的配置信息，比如，附着过程的无线资源控制（Radio Resource Control，RRC）释放消息。
这里，系统子组信息相关的配置信息可以包括天线端口数或预编码信息。
S302：根据配置信息接收用户设备所在用户设备群组对应的系统子组信息；
用户设备根据获取的配置信息，接收用户设备所在用户设备群组对应的系统子组信息。用户设备在接收系统子组信息后，可以根据系统子组信息决定是否执行进一步的操作。
比如对于一个宏小区用户设备，它可以根据接收的系统子组信息来判断是否去触发异频小区发现和测量。
对于一个D2D用户设备，它可以根据接收的系统子组信息来判断是否有可用的D2D资源存在。
对于一个支持NCT的用户设备，该用户设备可以根据接收的系统子组信息获取同覆盖的NCT系统信息。因为对于NCT用户设备优先选择NCT小区接收服务，如果发现驻留的服务小区的系统信息里指示有同覆盖的NCT小区的存在，则触发到NCT小区的切换。但NCT小区相对覆盖范围小，如果在全小区广播的，这样可能使得支持NCT的用户设备触发无用的测量和切换。
请参阅图5，图5是本发明实施例提供的第四种广播消息的方法的流程图，本实施例以用户设备的角度来进行描述，本实施例的广播消息的方法包括：
S401：用户设备接收公共系统信息；
基站预先向所有用户设备广播公共系统信息，用户设备接收该公共系统信息。
公共系统信息可提供映射信息在不同的系统子组信息对应的配置信息和辅助的识别指纹信息（Fingerprint Information）。其中，系统子组信息对应的配置信息如天线端口数或预编码信息。辅助的识别指纹信息可以是定位信息，也可以是1-3个相邻的和/或同覆盖的小区的信息（如频率、PCI、参考信号接收功率/参考信号接收质量等）。
其中，公共系统信息还可以进一步包括系统子组信息的标识或标号。
S402：用户设备获取用户设备所在用户设备群组对应的系统子组信息相关的配置信息；
基站向每个用户设备群组的用户设备广播用户设备群组对应的系统子组信息。用户设备需要预先获取用户设备所在用户设备群组对应的系统子组信息相关的配置信息，以用于接收对应的系统子组信息。
其中，处于连接态的用户设备可以通过专用信息获得用户设备所在用户设备群组对应的系统子组信息相关的配置信息。处于空闲态的用户设备可以通过附着过程的RRC释放消息获取用户设备所在用户设备群组对应的系统子组信息相关的配置信息。
这里，系统子组信息相关的配置信息可以包括天线端口数或预编码信息。
S403：根据配置信息接收用户设备所在用户设备群组对应的系统子组信息；
用户设备根据获取的配置信息，接收用户设备所在用户设备群组对应的系统子组信息。用户设备在接收系统子组信息后，可以根据系统子组信息决定是否执行进一步的操作。
比如对于一个宏小区用户设备，它可以根据接收的系统子组信息来判断是否去触发异频小区发现和测量。
对于一个D2D用户设备，它可以根据接收的系统子组信息来判断是否有可用的D2D资源存在。
对于一个支持NCT的用户设备，该用户设备可以根据接收的系统子组信息获取同覆盖的NCT系统信息。
S404：当用户设备接收到指示系统信息改变的信息或系统信息保持预定时间不变时，用户设备重新获取公共系统信息；
系统信息不会一直不变，在用户设备侧看来，如果系统信息长时间（例如：3小时）不变，用户设备会尝试重新获取系统信息。另外，如果网络侧系统信息发生改变了，那么网络侧就需要通知用户设备更新系统信息。对于连接态和空闲态的用户设备，都可以通过寻呼来通知。但是，系统信息不是随时都可以变更的，只在特定的无线帧处更新。由此引入修改周期的概念。在修改周期内的系统信息内容不能发生变化，系统信息修改只能从下一个修改周期起始时刻开始，即当得知系统信息改变后，在下一个修改周期开始时刻监听新的系统信息以重新获取系统信息。
长期演进（Long Term Evolution，LTE）两种系统信息变更的通知方式：1. 网络侧使用携带指示系统信息变更内容的寻呼消息来通知空闲状态和连接状态用户设备系统信息改变，用户设备在下一个修改周期开始时监听新的系统信息。2. SIB1中携带系统信息变更标签信息，如果用户设备读取的变更标签和之前存储的不同，则表示系统信息发生变更，需要重新读取；用户设备存储系统信息的有效期为3小时，超过该时间，用户设备需要重读系统信息。
当系统信息保持预定时间（3小时）不变或用户设备接收到寻呼或其他指示系统信息改变的信息，这时，用户设备重新获取公共系统信息。
S405：判断是否有用户设备所在用户设备群组对应的系统子组信息改变的指示信息；
在重新获取公共系统信息之后，可以根据重新获取的公共系统信息或指示系统信息改变的信息中，进一步判断是否有用户设备所在用户设备群组对应的系统子组信息改变的指示信息，从而决定是否需要重新获取对应的系统子组信息。
另一种情况，在用户设备发生移动的时候，也需要根据上述判断决定是否需要重新获取系统子组信息。
当有用户设备所在用户设备群组对应的系统子组信息改变的指示信息时，判断出需要进一步重新获取对应的系统子组信息，执行S406，否则，执行S407。
S406：重新获取用户设备所在用户设备群组对应的系统子组信息；
在需要重新获取用户设备群组对应的系统子组信息时，用户设备重新获取用户设备所在用户设备群组对应的系统子组信息。
S407：不执行操作。
在不需要重新获取用户设备群组对应的系统子组信息时，用户设备不执行操作。
用户设备在接收其所在区域对应的系统子组信息和/或上述重新获取用户设备所在用户设备群组对应的系统子组信息之后，可以根据系统子组信息进一步决定后续操作。
比如对于宏小区用户设备，可以根据系统子组信息来判断是否去触发异频小区发现和测量。
对于一个D2D用户设备，其可以根据系统子组信息来判断是否有可用的D2D资源存在。
对于一个支持NCT的用户设备，其可以根据系统子组信息，从宏小区获取同覆盖的NCT系统信息。
通过上述实施例的阐述，用户设备通过获取用户设备所在用户设备群组对应的系统子组信息相关的配置信息，并根据相关的配置信息获取用户设备所在用户设备群组对应的系统子组信息，可以根据系统子组信息确定是否执行进一步操作。通过这样的方式，使系统信息广播更加具有针对性，用户设备只接收跟自己有关的系统子组信息，不会因此而触发不必要的行为。
请参阅图6，图6是本发明实施例提供的第一种基站的结构示意图，本实施例的基站100包括确定模块11和广播模块12，其中：
确定模块11用于确定第一小区下的系统信息的至少一个系统子组信息，每个系统子组信息包括应用在与系统子组信息对应的用户设备群组的系统信息内容，其中，第一小区是指基站控制的一个小区，用户设备群组是第一小区下的至少一个用户设备组成的群体。
每个系统子组信息包括应用在与系统子组信息对应的用户设备群组的系统信息内容。具体地，每个用户设备群组对应的系统子组信息包括用户设备群组所在区域相邻的小小区信息、用于设备对设备通信连接的无线资源信息的至少一种。其中，第一小区是指基站控制的一个小区，用户设备群组是第一小区下的至少一个用户设备组成的群体。
比如用户设备群组1的系统子组信息可以包括用户设备群组1所在区域相邻的小小区信息，而小小区信息可以包括PCI、频率信息、专用参考信号信息、信道状态信息参考信号信息、公共的物理配置以及SIB信息中的至少一种。用户设备群组1的系统子组信息还可以包括可用的用于D2D通信连接的无线资源信息，而无线资源信息可以包括分配的资源、位置信息以及干扰水平中的至少一种。
每个用户设备群组对应的的系统子组信息通过PDSCH，或PDSCH和EPDCCH进行区分。比如，不同用户设备群组对应的系统子组信息使用的不同的PDSCH资源，同时不同的系统子组信息使用的PDCCH资源相同;或者不同的系统子组信息使用的不同的EPDCCH资源；或者不同的系统子组信息使用的不同的PDSCH资源，同时不同的系统子组信息使用不同的码资源对PDCCH进行加扰。
更进一步地，系统子组信息中还可以包括指示系统子组对应的标识或者标号或者子组指示。系统子组对应的标识或标号用于标识不同的系统子组信息，子组指示用于指示系统子组信息、用户设备群组与用户设备群组所在区域的对应关系。
确定模块11确定第一小区下的系统信息的至少一个系统子组信息可以是通过配置解调参考信号、扰码序列索引、天线端口以及预编码中的至少一种参数来实现。其中预编码可以是预定义的CRS。
其中，这些参数的配置可以是静态的，也可以是半静态的。比如可以根据用户设备群组所在区域的处于连接态UE上报的参考信号接收功率/参考信号接收质量，或者是对CSI上报取个长周期的平滑值，如平均值或加权平均值。
广播模块12用于根据确定模块11确定的第一小区下的系统信息的至少一个系统子组信息，向用户设备群组广播所述用户设备群组对应的系统子组信息。
广播模块12向用户设备群组广播用户设备群组对应的系统子组信息。比如基站通过广播模块12向用户设备群组1的用户设备广播系统子组信息1，向用户设备群组2、3分别广播系统子组信息2、3，其中，系统子组信息1包括应用在用户设备群组1的系统信息内容，系统子组信息2、3包括应用在用户设备群组2、3的系统信息内容。
本实施例中具体实现基站通过广播模块12向用户设备群组广播用户设备群组对应的系统子组信息的实现方式，可以包括：
1、广播模块12通过每个用户设备群组所在区域对应的波束向用户设备群组的用户设备广播用户设备群组对应的系统子组信息。
比如通过波束1来广播系统子组讯息1，通过波束2、3分别广播系统子组信息2、3。其中，波束1的波束宽度和波束指向可以覆盖用户设备群组1所在区域，波束2、3的波束宽度和波束指向分别可以覆盖用户设备群组2、3所在区域。
2、广播模块12通过每个用户设备群组所在区域对应的系统信息无线网络临时标识（SI-RNTI）向每个用户设备群组的用户设备广播每个用户设备群组对应的系统子组信息，每个用户设备群组对应的系统子组信息分别对应不同的系统信息无线网络临时标识。
当然，在可以实现本发明实施例目的的情况下，本领域技术人员也可以通过其他的实现方式来向每个用户设备群组的用户设备广播每个用户设备群组对应的系统子组信息。
广播模块12还用于广播公共系统信息，公共系统信息包括系统子组信息对应的配置信息和辅助的识别指纹信息。
公共系统信息可提供映射信息在不同的系统子组信息对应的配置信息和辅助的识别指纹信息（Fingerprint Information）。其中，系统子组信息对应的配置信息如天线端口数或预编码信息。辅助的识别指纹信息可以是定位信息，也可以是1-3个相邻的和/或同覆盖的小区的信息（如频率、PCI、参考信号接收功率/参考信号接收质量等）。
其中，公共系统信息还可以进一步包括系统子组信息的标识或标号。
本实施例所述的基站能够执行上述图1所示实施例的广播消息的方法中各个步骤，本实施例的基站各个功能模块的划分只是示意性的，在能够实现本发明目的的基础上，其功能模块的划分并不限于以上方式，可以是其他任何可能实现的方式。例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。
请参阅图7，图7是本发明实施例提供的第二种基站的结构示意图，本实施例的基站200包括确定模块21、广播模块22、划分模块23以及设置模块24，其中：
确定模块21用于确定第一小区下的系统信息的至少一个系统子组信息，每个系统子组信息包括应用在与系统子组信息对应的用户设备群组的系统信息内容，其中，第一小区是指基站控制的一个小区，用户设备群组是第一小区下的至少一个用户设备组成的群体。
广播模块22用于根据确定模块21确定的第一小区下的系统信息的至少一个系统子组信息，向用户设备群组广播用户设备群组对应的系统子组信息。
其中，确定模块21与广播模块22的具体功能实现跟实施例6所述的基本一致，请参阅图6所示实施例的详细描述，在此不再赘述。
划分模块23用于将用户设备划分为不同的用户设备群组。其中，划分模块23可以将第一小区下的不同的区域的用户设备分别划分为不同的用户设备群组；或将第一小区下的不同种类的用户设备分别划分为不同的用户设备群组；或将第一小区下的运行不同业务类型的用户设备分别划分为不同的用户设备群组。
划分模块23用于根据邻区关系的聚集情况将用户设备群组划分为不同的区域；或用于根据用户设备的数量将用户设备群组划分为不同的区域。
基站通过划分模块23可以预先将其控制范围的用户设备群组划分为不同的区域。
具体实现时，区域之间的分界线可以根据邻区关系的聚集情况来界定，如某个区域的小小区较密集部署，可以在那里形成一个区域，该区域内的用户设备划分到属于该区域。
又或者，区域之间的分界线可以由用户设备的数量来决定。如当某区域的用户设备的数量较多时，可以将该分界线向里设置，即将区域设置得小一些，当用户设备的数量较小时，可以将该分界线向外设置，即将区域设置得更大一些，以容纳更多的用户设备。具体的用户设备的数量可以根据实际情况而设定，不同的用户设备群组对应的区域在宏小区内可以是连续覆盖，也可以是离散覆盖的。
其中，区域的划分可以是静态的，也可以是半静态的。比如用户设备A固定划分到区域1，或者用户设备A第一时间段划分到区域1，第二时间段划分到区域2或区域3等等。其中，第一时间段与第二时间段的时间间隔为预先设定的某个值，比如1个月、3个月或者1年等等。
当用户设备群组所在区域发生变化时，如果是通过波束向用户设备群组的用户设备发送该用户设备群组对应的系统子组信息，设置模块24可以通过调整高定向性天线的波束宽度和波束指向即可实现通过波束对改变后的区域发送系统子组信息。
当广播模块22通过每个用户设备群组所在区域对应的波束向每个用户设备群组的用户设备广播每个用户设备群组对应的系统子组信息时，设置模块24用于根据每个用户设备群组所在区域的位置信息设置高定向性天线的波束宽度和波束指向，以使得高定向性天线形成的波束能够覆盖其对应的区域。广播模块22通过设置模块24设置的高定向性天线形成的波束广播相应的系统子组信息。
具体地，设置模块24获取用户设备群组所在区域的位置信息，然后根据该区域的位置信息，使用波束成性算法来来设置高定向性天线的波速宽度和波束指向。其中，不同热点地区对应的高定向性天线的波束宽度和波束执行是不同的。与波束宽度和波束指向对应的波束可以覆盖该区域。其中，位置信息可以是以下至少一个区域的面积、形状、方位角等。
其中，基站可以利用高定向性天线形成的至少两个波束对至少两个区域形成覆盖。
高定向性天线形成的波束中提供用户设备群组所在区域的系统子组信息对应的公共控制信道、业务信道等多个物理信道。
另外，更进一步的，设置模块24可以根据需要某个系统子组信息的区域的数量来灵活设置高定向性天线的数量。若需要该系统子组信息的区域的数量较少，基站可以根据区域的位置信息设置一个高定向性天线的数量。
比如若数量较少，设置模块24可以根据区域的位置信息设置一个高定向性天线的波束宽度和波束指向，利用该高定向性天线为需要某个系统子组信息的所有区域提供系统子组信息。
若数量较多，设置模块24可以根据位置信息设置高定向性天线的波束宽度和波束指向，不同的高定向性天线分别为不同的区域提供对应的系统子组信息，可以在多个高定向性天线之间灵活分配资源。举例来说，在一个实施例中如果区域数为4个，那么可以根据这4个区域的位置信息设置两个高定向性天线的波束宽度和波束指向，使每个高定向性天线分别为两个区域提供系统子组信息。
高定向性天线可以为阵列天线，当然还可以为其它类型的天线，例如在信号频率较高时，例如微波频段，则高定向性天线可以为抛物面天线。当采用线性阵列时，由于在垂直方向上没有形成波束，则可以形成扇形微小区。当采用平面阵列时，可以是32阵元的8×4均匀平面阵列，则可以在水平和垂直两个方向同时形成较窄的波束，即3D波束成型，也就是同时在水平和垂直方案形成波束，从而可以更好地生成区域覆盖。另外，还可以是圆形阵列和三维网格阵列天线也能实现3D波束成型。
在广播模块22通过高定向性天线形成的波束来广播系统子组信息时，多个用户设备群组对应的系统子组信息之间可能存在干扰，因此，在利用波束进行系统子组信息广播之前，广播模块22可以先对每个用户设备群组对应的系统子组信息进行多用户多入多出（Multiple User-Multiple Input Multiple Output，MU-MIMO）预编码，在预编码完成后，再通过波束广播经预编码后的系统子组信息。
广播模块22利用高定向性天线形成的波束向多个用户设备群组的用户设备分别广播对应的预编码后的系统子组信息。本实施例中，广播模块22通过预先设置合适的预编码向量，可以消除不同的多个用户设备群组的系统子组信息之间的干扰，可以进一步提高通行系统容量。
用户设备可以通过公共系统信息中获取的预编码信息，对应接收用户设备群组所在区域对应的预编码的系统子组信息，并根据系统子组信息执行后续操作。
比如当用户设备为第一小区（比如宏小区）用户设备时，用户设备可以根据系统子组信息来判断是否去触发异频小区发现和测量。
当用户设备为D2D用户设备时，其可以根据系统子组信息来判断是否有可用的D2D资源存在。

请参阅图8，图8是本发明实施例提供的第三种基站的结构示意图，本实施例中的基站300包括处理器31、存储器32、接收器33、发送器34以及总线系统35，其中：
处理器31控制基站300的操作，处理器31还可以称为CPU（Central Processing Unit，中央处理单元）。处理器31可能是一种集成电路芯片，具有信号的处理能力。处理器31还可以是通用处理器、数字信号处理器（DSP）、专用集成电路（ASIC）、现成可编程门阵列（FPGA）或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件。通用处理器可以是微处理器或者该处理器也可以是任何常规的处理器等。
存储器32可以包括只读存储器和随机存取存储器，并向处理器31提供指令和数据。存储器32的一部分还可以包括非易失性随机存取存储器（NVRAM）。
基站300的各个组件通过总线系统35耦合在一起，其中总线系统35除包括数据总线之外，还可以包括电源总线、控制总线和状态信号总线等。但是为了清楚说明起见，在图中将各种总线都标为总线系统35。
存储器32存储了如下的元素，可执行模块或者数据结构，或者它们的子集，或者它们的扩展集:
操作指令：包括各种操作指令，用于实现各种操作。
操作系统：包括各种系统程序，用于实现各种基础业务以及处理基于硬件的任务。
在本发明实施例中，处理器31通过调用存储器32存储的操作指令（该操作指令可存储在操作系统中），执行如下操作：
处理器31确定第一小区下的系统信息的至少一个系统子组信息，每个系统子组信息包括应用在与系统子组信息对应的用户设备群组的系统消息内容，控制发送器34向用户设备群组广播用户设备群组对应的系统子组信息，其中，第一小区是指基站控制的一个小区，用户设备群组是第一小区下的至少一个用户设备组成的群体。
处理器31还用于控制接收器33从网络接收通信数据。
存储器32还用于存储每个用户设备群组对应的系统子组信息。
每个系统子组信息包括应用在与系统子组信息对应的用户设备群组的系统信息内容。具体地，每个用户设备群组对应的系统子组信息包括用户设备群组所在区域相邻的小小区信息、用于设备对设备通信连接的无线资源信息的至少一种。其中，第一小区是指基站控制的一个小区，用户设备群组是第一小区下的至少一个用户设备组成的群体。
比如用户设备群组1的系统子组信息可以包括用户设备群组1所在区域相邻的小小区信息，而小小区信息可以包括PCI、频率信息、专用参考信号信息、信道状态信息参考信号信息、公共的物理配置以及SIB信息中的至少一种。用户设备群组1的系统子组信息还可以包括可用的用于D2D通信连接的无线资源信息，而无线资源信息可以包括分配的资源、位置信息以及干扰水平中的至少一种。
每个用户设备群组对应的的系统子组信息通过PDSCH，或PDSCH和EPDCCH进行区分。比如，不同用户设备群组对应的系统子组信息使用的不同的PDSCH资源，同时不同的系统子组信息使用的PDCCH资源相同;或者不同的系统子组信息使用的不同的EPDCCH资源；或者不同的系统子组信息使用的不同的PDSCH资源，同时不同的系统子组信息使用不同的码资源对PDCCH进行加扰。
更进一步地，系统子组信息中还可以包括指示系统子组对应的标识或者标号或者子组指示。系统子组对应的标识或标号用于标识不同的系统子组信息，子组指示用于指示系统子组信息、用户设备群组与用户设备群组所在区域的对应关系。
具体地，处理器31确定第一小区下的系统信息的至少一个系统子组信息可以是通过配置解调参考信号、扰码序列索引、天线端口以及预编码中的至少一种参数来实现。其中预编码可以是预定义的CRS。
其中，这些参数的配置可以是静态的，也可以是半静态的。比如可以根据用户设备群组所在区域的处于连接态UE上报的参考信号接收功率/参考信号接收质量，或者是对CSI上报取个长周期的平滑值，如平均值或加权平均值。
处理器31进一步控制发送器34向用户设备群组广播用户设备群组对应的系统子组信息。比如向用户设备群组1的用户设备广播系统子组信息1，向用户设备群组2、3分别广播系统子组信息2、3，其中，系统子组信息1包括应用在用户设备群组1的系统信息内容，系统子组信息2、3包括应用在用户设备群组2、3的系统信息内容。
具体地，处理器31可以通过每个用户设备群组所在区域对应的波束向用户设备群组的用户设备广播用户设备群组对应的系统子组信息；或通过每个用户设备群组所在区域对应的系统信息无线网络临时标识向每个用户设备群组的用户设备广播每个用户设备群组对应的系统子组信息，每个用户设备群组对应的系统子组信息分别对应不同的系统信息无线网络临时标识。
当然，在能实现本发明目的的前提下，处理器31也可以采用其他的实现方式来向每个用户设备群组的用户设备广播每个用户设备群组对应的系统子组信息。
当处理器31通过波束来广播相应的系统子组信息时，可以根据每个用户设备群组所在区域的位置信息设置高定向性天线的波束宽度和波束指向，以使得高定向性天线形成的波束能够覆盖其对应的区域。通过设置的高定向性天线形成的波束来广播相应的系统子组信息。
具体地，处理器31获取用户设备群组所在区域的位置信息，然后根据该区域的位置信息，使用波束成性算法来来设置高定向性天线的波速宽度和波束指向。其中，不同热点地区对应的高定向性天线的波束宽度和波束执行是不同的。与波束宽度和波束指向对应的波束可以覆盖该区域。其中，位置信息可以是以下至少一个区域的面积、形状、方位角等。
其中，处理器31可以利用高定向性天线形成的至少两个波束对至少两个区域形成覆盖。
高定向性天线形成的波束中提供区域的系统子组信息对应的公共控制信道、业务信道等多个物理信道。
另外，更进一步的，处理器31可以根据需要某个系统子组信息的区域的数量来灵活设置高定向性天线的数量。若需要该系统子组信息的区域的数量较少，基站可以根据区域的位置信息设置一个高定向性天线的数量。
比如若数量较少，处理器31可以根据区域的位置信息设置一个高定向性天线的波束宽度和波束指向，利用该高定向性天线为需要某个系统子组信息的所有区域提供系统子组信息。
若数量较多，处理器31可以根据位置信息设置高定向性天线的波束宽度和波束指向，不同的高定向性天线分别为不同的区域提供对应的系统子组信息，可以在多个高定向性天线之间灵活分配资源。举例来说，在一个实施例中如果区域数为4个，那么可以根据这4个区域的位置信息设置两个高定向性天线的波束宽度和波束指向，使每个高定向性天线分别为两个区域提供系统子组信息。
高定向性天线可以为阵列天线，当然还可以为其它类型的天线，例如在信号频率较高时，例如微波频段，则高定向性天线可以为抛物面天线。当采用线性阵列时，由于在垂直方向上没有形成波束，则可以形成扇形微小区。当采用平面阵列时，可以是32阵元的8×4均匀平面阵列，则可以在水平和垂直两个方向同时形成较窄的波束，即3D波束成型，也就是同时在水平和垂直方案形成波束，从而可以更好地生成区域覆盖。另外，还可以是圆形阵列和三维网格阵列天线也能实现3D波束成型。
当通过高定向性天线形成的波束来广播系统子组信息时，多个用户设备群组对应的系统子组信息之间可能存在干扰，因此，在利用波束进行系统子组信息广播之前，处理器31可以先对用户设备群组对应的系统子组信息进行MU-MIMO预编码，在预编码完成后，再通过波束广播经预编码后的系统子组信息。
另外，处理器31还用于广播公共系统信息，公共系统信息包括系统子组信息对应的配置信息和辅助的识别指纹信息。
公共系统信息可提供映射信息在不同的系统子组信息对应的配置信息和辅助的识别指纹信息（Fingerprint Information）。其中，系统子组信息对应的配置信息如天线端口数或预编码信息。辅助的识别指纹信息可以是定位信息，也可以是1-3个相邻的和/或同覆盖的小区的信息（如频率、PCI、参考信号接收功率/参考信号接收质量等）。
其中，公共系统信息还可以进一步包括系统子组信息的标识或标号。
在另一个实施例中，处理器31还用于将用户设备划分为不同的用户设备群组。其中，处理器31可以将第一小区下的不同的区域的用户设备划分为不同的用户设备群组，或将第一小区下的不同种类的用户设备分别划分为不同的用户设备群组，或将第一小区下的运行不同业务类型的用户设备分别划分为不同的用户设备群组。
在另一个实施例中，处理器31还可以根据邻区关系的聚集情况将用户设备群组划分为不同的区域；或根据用户设备的数量将用户设备群组划分为不同的区域。
处理器31可以将基站控制范围的用户设备划分为不同的区域。具体实现时，区域之间的分界线可以根据邻区关系的聚集情况来界定，如某个区域的小小区较密集部署，可以在那里形成一个区域，该区域内的用户设备划分到属于该区域。
又或者，区域之间的分界线可以由用户设备的数量来决定。如当某区域的用户设备的数量较多时，可以将该分界线向里设置，即将区域设置得小一些，当用户设备的数量较小时，可以将该分界线向外设置，即将区域设置得更大一些，以容纳更多的用户设备。具体的用户设备的数量可以根据实际情况而设定，不同的用户设备群组对应的区域在宏小区内可以是连续覆盖，也可以是离散覆盖的。
其中，区域的划分可以是静态的，也可以是半静态的。比如用户设备A固定划分到区域1，或者用户设备A第一时间段划分到区域1，第二时间段划分到区域2或区域3等等。其中，第一时间段与第二时间段的时间间隔为预先设定的某个值，比如1个月、3个月或者1年等等。
当用户设备群组所在区域发生变化时，如果是通过波束向用户设备群组的用户设备发送该用户设备群组对应的系统子组信息，处理器31可以通过调整高定向性天线的波束宽度和波束指向即可实现通过波束对改变后的区域发送系统子组信息。
上述本发明实施例揭示的方法可以应用于处理器31中，或者由处理器31实现。在实现过程中，上述方法的各步骤可以通过处理器31中的硬件的集成逻辑电路或者软件形式的指令完成。可以实现或者执行本发明实施例中的公开的各方法、步骤及逻辑框图。结合本发明实施例所公开的方法的步骤可以直接体现为硬件译码处理器执行完成，或者用译码处理器中的硬件及软件模块组合执行完成。软件模块可以位于随机存储器，闪存、只读存储器，可编程只读存储器或者电可擦写可编程存储器、寄存器等本领域成熟的存储介质中。该存储介质位于存储器32，处理器31读取存储器32中的信息，结合其硬件完成上述方法的步骤。
请参阅图9，图9是本发明实施例提供的第一种用户设备的结构示意图，本实施例的用户设备400包括获取模块41和接收模块42，其中：

基站向每个用户设备群组的用户设备广播用户设备群组对应的系统子组信息。用户设备需要预先通过获取模块41获取用户设备所在用户设备群组对应的系统子组信息相关的配置信息，以用于接收对应的系统子组信息。
其中，处于连接态的用户设备的获取模块41可以通过专用信息获得用户设备所在用户设备群组对应的系统子组信息相关的配置信息。处于空闲态的用户设备的获取模块42可以通过附着过程的无线资源控制（Radio Resource Control，RRC）释放消息获取用户设备所在用户设备群组对应的系统子组信息相关的配置信息。

接收模块42用于根据获取模块41获取的配置信息接收用户设备所在用户设备群组对应的系统子组信息。
接收模块42根据获取模块41获取的配置信息，接收用户设备所在用户设备群组对应的系统子组信息。用户设备在接收系统子组信息后，可以根据系统子组信息决定是否执行进一步的操作。
本实施例的用户设备能够执行图3所示实施例的广播消息的方法的各个步骤，其模块、功能的实现在本发明实施例中只是示意性说明，在能够实现本发明目的的基础上，其功能模块的划分并不限于以上方式，可以是其他任何可能实现的方式。例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。

接收模块52用于根据获取模块51获取的配置信息接收用户设备所在用户设备群组对应的系统子组信息。
其中，获取模块51以及接收模块52的具体功能实现与图9所示实施例的基本相同，请参阅图9所示实施例的详细描述，这里不再赘述。
本实施例中的接收模块52还用于接收指示系统信息改变的信息，获取模块51用于在接收模块52接收到指示系统信息改变的信息或系统信息保持预定时间不变时，重新获取公共系统信息。
系统信息不会一直不变，在用户设备侧看来，如果系统信息长时间（例如：3小时）不变，用户设备会尝试重新获取系统信息。另外，如果网络侧系统信息发生改变了，那么网络侧就需要通知用户设备更新系统信息。对于连接态和空闲态的用户设备，都可以通过寻呼来通知。但是，系统信息不是随时都可以变更的，只在特定的无线帧处更新。由此引入修改周期的概念。在修改周期内的系统信息内容不能发生变化，系统信息修改只能从下一个修改周期起始时刻开始，即当得知系统信息改变后，在下一个修改周期开始时刻监听新的系统信息以重新获取系统信息。
当系统信息保持预定时间（例如：3小时）不变或用户设备接收到寻呼或其他指示系统信息改变的信息，这时，用户设备重新获取公共系统信息。
判断模块53用于判断是否有用户设备所在用户设备群组对应的系统子组信息改变的指示信息。
其中，判断模块53可以从指示系统信息改变的信息或重新获取的公共系统信息中，判断是否有用户设备所在用户设备群组对应的系统子组信息改变的指示信息。其中，指示系统信息改变的信息可以是寻呼消息。
另一种情况，在用户设备发生移动的时候，也需要根据上述判断决定是否需要重新获取系统子组信息。

请进一步参阅图11，图11是本发明实施例提供的第三种用户设备的结构示意图，本实施例的用户设备600包括处理器61、存储器62、接收器63、发送器64以及总线系统65，其中：
处理器61控制用户设备600的操作，处理器61还可以称为CPU（Central Processing Unit，中央处理单元）。处理器61可能是一种集成电路芯片，具有信号的处理能力。处理器31还可以是通用处理器、数字信号处理器（DSP）、专用集成电路（ASIC）、现成可编程门阵列（FPGA）或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件。通用处理器可以是微处理器或者该处理器也可以是任何常规的处理器等。

存储器62存储了如下的元素，可执行模块或者数据结构，或者它们的子集，或者它们的扩展集:
操作指令：包括各种操作指令，用于实现各种操作。

当系统信息保持预定时间（例如：3小时）不变或用户设备接收到寻呼或其他指示系统信息改变的信息，这时，处理器61重新获取公共系统信息。
在重新获取公共系统信息后，处理器61进一步判断是否有用户设备所在用户设备群组对应的系统子组信息改变的指示信息。
其中，处理器61可以从指示系统信息改变的信息或重新获取的公共系统信息中，判断是否有用户设备所在用户设备群组对应的系统子组信息改变的指示信息。其中，指示系统信息改变的信息可以是寻呼消息。
