下面结合附图对本发明实施例进行说明。
实施例1
本实施例提供了一种传输资源的传输方向的配置方法，该方法应用于基站，图1是本实施例的方法的示意图，如图1所示，该方法包括：
步骤101：基站向用户设备发送指示信息，指示所述用户设备在某时间窗内某个或某些时间段的传输方向发生了改变，该指示信息包括传输方向发生了改变的时间段的位置信息。
在本实施例中，该基站是指该用户设备的服务基站，如前所述，可以是宏基站(例如eNB)，该宏基站产生的宏小区(例如Macro cell)可以为用户设备提供服务；也可以是微基站，该微基站产生的微小区(例如Pico cell)可以为用户设备提供服务； 也可以为其他服务基站。本发明不限于此，可以根据实际的需要确定具体的场景。
在本实施例中，该用户设备是在上述基站的服务下的用户设备，其可以是前述UE的任意一种，本发明实施例并不以此作为限制。
在本实施例中，预先定义了时间窗的概念，其可以是一个帧，也可以是一个子帧，或者是一个时隙。该时间窗包含多个时间单元(time unit)，该时间单元例如可以是正交频分复用(OFDM，Orthogonal Frequency Division Multiplexing)符号。图2是一个时间窗的示意图，如图2所示，例如在该时间窗内包含10个时间单元。图2只是举例说明，并不构成对本发明实施例的时间窗的限制。
在本实施例中，如果系统针对一个用户设备，将某时间窗配置成下行或上行传输，网络侧(例如前述的基站)可以向该用户设备发送指示信息，以改变该时间窗内某个或某些时间段的传输方向，由此实现了动态的上下行传输资源的需求。
在本实施例中，该传输方向发生了改变的时间段可以位于该时间窗的前部，也可以位于该时间窗的中部，或者位于该时间窗的后部，甚至可以位于该时间窗内多个分开的位置。
图3是传输方向发生了改变的一个示例，如图3所示，系统将该时间窗配置成下行传输，网络侧通过向用户设备发送指示信息来指示改变了该时间窗内前四个时间单元的传输方向。也即，在该示例中，该传输方向发生了改变的时间段位于该时间窗的前部。
图4是传输方向发生了改变的另一个示例，如图4所示，系统将该时间窗配置成下行传输，网络侧通过向用户设备发送指示信息来指示改变了该时间窗内后三个时间单元的传输方向。也即，在该示例中，该传输方向发生了改变的时间段位于该时间窗的后部。
图5是传输方向发生了改变的另一个示例，如图5所示，系统将该时间窗配置成下行传输，网络侧通过向用户设备发送指示信息来指示改变了该时间窗内第三个到第七个时间单元的传输方向。也即，在该示例中，该传输方向发生了改变的时间段位于该时间窗的中部。
图6是传输方向发生了改变的另一个示例，如图6所示，系统将该时间窗配置成下行传输，网络侧通过向用户设备发送指示信息来指示改变了该时间窗内第二、三、六、七个时间单元的传输方向。也即，在该示例中，该传输方向发生了改变的时间段 位于该时间窗内多个分开的位置。
图7-图10是传输方向发生了改变的另一个示例，如图7-10所示，系统将该时间窗配置成上行传输，网络侧通过向用户设备发送指示信息来指示改变了该时间窗内某个或某些时间段的传输方向，并且传输方向发生了改变的时间段位于该时间窗的前部(图8所示)、后部(图7所示)、或者多个分开的位置(图9所示为两个分开的位置、图10所示为三个分开的位置)。
图3-图10是以传输方向发生了改变的时间段包含整数个时间单元为例，但本实施例并不以此作为限制，在其他实施方式中，该传输方向发生了改变的时间段也可以包含非整数个时间单元。
在本实施例中，如前所述，该指示信息包括了传输方向发生了改变的时间段的位置信息，例如时频资源的位置，可以是起始位置和结束位置，也可以是起始位置和长度，通过该位置信息，可以确定该传输方向发生了改变的时间段。
在本实施例中，可选的，该指示信息还可以包括传输方向发生了改变的时间段内物理信号的特征，例如波形、符号长度、循环前缀长度、传输时间间隔(TTI，Transmission time interval)长度、子载波间隔等。由于这部分资源的传输方向发生了改变，相应的物理信号(或物理信道)的特征也发生了改变，该基站可以将这部分资源的物理信号的特征通过上述指示信息发给用户设备，以便用户设备据此进行后续处理。
在本实施例中，可选的，该指示信息还可以包括传输方向发生了改变的时间段的传输方向，例如上行或者下行，对于指示方式，本实施例不作限制。
在本实施例中，可选的，如果该传输方向发生了改变的时间段导致在该时间窗内出现了下行向上行的转换，如图11所示，则该指示信息中还可以包括保护间隔的长度，该保护间隔可以占用下行资源也可以占用上行资源。可选的，在该实施方式中，除了该保护间隔的长度，该指示信息还可以包括该保护间隔所占用的资源，例如上行资源或者下行资源，或者包括该保护间隔的位置，以表明该保护间隔所占用的资源是上行资源还是下行资源。
在本实施例中，可选的，当改变该时间窗内某个或某些时间段的上下行配置时，服务点，例如基站或者远端无线头(RRH，Remote Radio Head)等，也发生了改变，则该指示信息中还可以包括该新的服务点的标识信息，例如，该新的服务点的标识， 或者被该新的服务点服务的小区的标识等。
如图12所示，某个时间窗的前四个时间单元由下行变为上行，同时上行的服务点由TP1变为TP2，则该指示信息中还可以包含该TP2的标识信息，例如该TP2的标识或者被该TP2服务的小区的标识等。在本实施例中，如果服务点没有发生改变，则在指示信息中无需加入该服务点的标识信息。
在本实施例中，该基站可以利用该时间窗内的前部的下行资源发送上述指示信息，这种发送方式适用于该传输方向发生了改变的时间段位于该时间窗的前部或后部的情况。在本实施例中，该基站也可以利用该时间窗之前的时间窗内的下行资源发送上述指示信息，这种发送方式适用于该传输方向发生了改变的时间段位于该时间窗的任意位置的情况。在本实施例中，该基站也可以利用该时间窗内传输方向发生了改变的时间段之前的下行资源发送上述指示信息，这种发送方式适用于在该时间窗内的该传输方向发生了改变的时间段之前存在下行资源的情况。
通过本实施例的方法，基站向用户设备发送指示信息以改变某时间窗内某个或某些时间段的资源的传输方向，满足了动态的上下行传输资源的需求。
