在现有技术中，在基站发送的下行控制信息中定义了相应字段，用于承载相应的指示信息。对于第一种多用户叠加传输类型，指示信息包括两个字段：第一字段用于指示是否存在干扰，第二字段用于指示功率配比值。对于第三种多用户叠加传输类型，指示信息包括三个字段，第一字段用于指示是否存在干扰，第二字段用于指示配对用户的调制方式，第三字段用于指示配对用户的预编码向量。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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，所描述的实施例是本发明一部分实施例，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作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例涉及的消息的处理方法，可用于LTE/LTE-A系统下的MUST通信中。在MUST通信中包括多种MUST传输类型，其中，第一种多用户叠加传输类型为基站采用相同空分复用的传输模式服务两个配对用户终端且为两个用户终端分配的预编码向量相同；第三种多用户叠加传输类型为基站采用相同空分复用的传输模式服务两个配对的用户终端且为两个用户终端分配的预编码向量不同。为了能够使得进行MUST传输的终端设备对信息进行正确接收，基站需要通知终端设备传输类型对应的传输参数。在现有技术中，基站可以在发送的下行控制信息中定义相应的字段，用于承载传输参数。对于第一种多用户叠加传输类型，指示信息包括两个字段：第一字段用于指示是否存在干扰，第二字段用于指示功率配比值。对于第三种多用户叠加传输类型，可以在指示信息中另外定义三个字段，第一字段用于指示是否存在干扰，第二字段用于指示配对用户的调制方式，第三字段用于指示配对用户的预编码向量。这样，就需要在下行控制信息中采用多个字段同时指示传输类型及该传输类型对应的传输参数，使得下行控制信息的开销非常大。
因此，本发明实施例提供的消息的处理方法和装置，旨在解决现有技术中的下行控制信息的开销较大，造成系统的传输效率较低的技术问题。
下面以具体地实施例对本发明的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图1为本发明消息的处理方法实施例一的流程示意图。本发明实施例提供了一种消息的处理方法，该方法可以由任意执行消息的处理方法的装置来执行，该装置可以通过软件和/或硬件实现。本实施例中，该装置可以集成在基站中。如图1所示，本实施例的方法可以包括：
步骤101、基站确定向终端设备发送信息的传输类型和传输类型对应的传输参数。
步骤102、基站向终端设备发送携带指示字段的通知消息，该指示字段用于指示传输类型和传输参数，以使终端设备根据传输类型和传输参数接收数据，该指示字段的至少一种状态指示传输类型为第一种多用户叠加传输类 型，该指示字段的至少一种状态指示传输类型为第三种多用户叠加传输类型。
在本实施例中，基站在确定出向终端设备发送信息的传输类型和该传输类型对应的传输参数之后，将向该终端设备发送携带有指示字段的通知消息，该指示字段的至少一种状态可以指示传输类型为第一种多用户叠加传输类型，指示字段的至少一种状态也可以指示传输类型为第三种多用户叠加传输类型。终端设备在接收到基站发送的携带有指示字段的通知消息后，将根据该指示字段指示的传输类型和传输参数接收数据。
需要进行说明的是，通知消息可以采用显示的方式携带指示字段，也可以采用隐式的方式携带指示字段，例如通过在通知消息中加扰码的方式来携带指示字段。
另外，该指示字段还可以包括至少两部分，本实施例中以两部分为例进行说明，其中，第一部分用于指示第一种多用户传输类型及对应的传输参数，第二部分用于指示第二种多用户传输类型及对应的传输参数。
具体地，当基站采用秩为2的空分复用传输类型为终端设备传输数据时，指示字段指示的传输类型可以包括单用户传输和第一种多用户叠加传输类型；当基站采用秩为1的空分复用传输模式为终端设备传输数据时，指示字段指示的传输类型包括单用户传输、第一种多用户叠加传输类型和第三种多用户叠加传输类型。
可选地，若指示字段指示的传输类型为第一种多用户叠加传输类型时，该指示字段指示的传输参数包括终端设备和配对终端设备的功率配比。
具体的，当基站采用秩为2的空分复用传输模式向终端设备发送信号且基站采用秩为1的空分复用传输模式向终端设备发送信号时，所述终端设备和配对终端设备的功率配比为基站在第一空间层上向终端设备发送第一信号与基站在第一空间层上向配对终端设备发送第二信号的功率配比。另外，基站在第一空间层和第二空间层上向终端设备发送信号的功率相等，同时基站不在第二空间层上向配对终端设备发送信号。其中，第一信号为终端设备需要的信号，而第二信号为配对终端设备需要的信号。
为了方便理解，将基站在第一空间层上向终端设备发送的第一信号表示为x，将基站在第二空间层上向终端设备发送的信号表示为y，将基站在第一空间层上向配对终端设备发送的第二信号表示为z，则x与y的功率相等。
可选地，若指示字段指示的传输类型为第三种多用户叠加传输类型时，该指示字段指示的传输参数包括终端设备与配对终端设备的功率配比，配对终端设备的预编码信息和配对终端设备的调制方式中的至少一个。
具体地，当指示字段指示的传输类型为第三种多用户叠加传输类型，指示的传输参数包括配对终端设备的预编码信息，指示字段的取值与传输类型和传输参数之间的对应关系如表1所示。另外，指示字段指示第一种多用户叠加传输类型对应的功率配比值不限于4种，指示字段指示第三种多用户叠加传输类型对应的预编码信息不限于3个。
