频带配置装置、方法以及通信系统 技术领域
本发明涉及通信技术领域，特别涉及一种半双工系统中的频带配置装置、方法以及通信系统。
背景技术
在现有的半双工(Half Duplex)系统中，一个频带要么被配置成时分复用(TDD，Time Division Duplex)频带，要么被配置成频分复用(FDD，Frequency Division Duplex)频带。具体来说，TDD频带会使用一个载频(例如f1)在不同时隙内被分配为上行传输或下行传输，而FDD频带会包含两个不同的载频(例如f1和f2)，分别用作上行传输和下行传输。因此，对于处在同一小区的用户设备(UE，User Equipment)来说，在同一时间，只能在同一频率上进行上行传输或者进行下行传输。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。

实施例1
本发明实施例提供一种频带配置方法，应用于半双工系统的用户设备。图1是本发明实施例的频带配置方法的一示意图，如图1所示，所述频带配置方法包括：
步骤101，用户设备确定一半双工频带，并获得该半双工频带的配置信息；
步骤102，用户设备接收网络侧设备发送的用于重新配置该半双工频带的指示信息；其中该指示信息指示该半双工频带既被用于上行传输也被用于下行传输。
在本实施例中，网络侧设备可以为宏基站(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；或者网络侧设备也可以为微基站，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；或者网络侧设备也可以为其他设备。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，该半双工频带可以为TDD频带，或者也可以为FDD的下行频带，或者也可以为FDD的上行频带，或者还可以为非授权频带。当用户设备搜索到一个半双工频带后，可以接收到网络侧设备(例如基站)发送的系统消息(例如SIB1)，该系统消息中指示了该频带的配置信息。由此，用户设备可以根据该配置信息确定该半双工频带是TDD频带还是FDD频带等。
在本实施例中，在搜索到该半双工频带并获得相应的配置信息之后，用户设备还可以接收到网络侧设备发送的重新配置该半双工频带的指示信息；其中该指示信息指示该半双工频带既被用于上行传输也被用于下行传输。
例如，当用户设备搜索到一个频带后，接收到基站(例如eNB)发送的系统消息(例如SIB1)指示了该频带的TDD配置信息，则该用户设备就将该频带认定为TDD频带。此外，该基站会发送指示信息来指明该TDD频带可以同时作为上行频带和下行频带。因此，该TDD频带被动态地重新进行了配置。可选的，该指示信息中可以指定该频带的相关信息，例如载波频率、带宽等。
图2是本发明实施例的TDD频带被动态配置为上行频带和下行频带的一示意图。如图2所示，该传统的TDD频带的载频为f1，TDD配置信息指示该TDD频带包括2个上行子帧和4个下行子帧，即在某一时刻，该TDD频带只能进行上行传输(在上行子帧上)或者进行下行传输(在下行子帧上)。在被指示信息重新配置之后，该TDD频带在任意时刻，均可以进行上行传输和下行传输。至于在某一时刻具体是上行传输还是下行传输，例如可以由调度信息确定。
再例如，当用户设备搜索到一个频带后，接收到基站(例如eNB)发送的系统消息(例如SIB2)指示了与该频带对应的FDD配置信息，则该用户设备就将该频带认定为FDD下行频带。此外，该基站会发送指示信息来指明该FDD下行频带可以同时作为上行频带和下行频带。因此，该FDD下行频带被动态地重新进行了配置。可选的，该指示信息中可以指定该频带的相关信息，例如载波频率、带宽等。
图3是本发明实施例的FDD下行频带被动态配置为上行频带和下行频带的一示意图。如图3所示，该传统的FDD下行频带的载频为f1，FDD上行频带的载频为f2，即在任一时刻，该FDD下行频带只能进行下行传输。在被指示信息重新配置之后，该FDD下行频带在任意时刻，均可以进行上行传输和下行传输。至于在某一时刻具体是上行传输还是下行传输，例如可以由调度信息确定。
再例如，当用户设备搜索到一个频带后，接收到基站(例如eNB)发送的系统消息(例如SIB2)指示了与该频带对应的FDD配置信息，则该用户设备就将该频带对应的上行频带认定为FDD上行频带。此外，该基站会发送指示信息来指明该FDD上行频带可以同时作为上行频带和下行频带。因此，该FDD上行频带被动态地重新进行了配置。可选的，该指示信息中可以指定该频带的相关信息，例如载波频率、带宽等。
图4是本发明实施例的FDD上行频带被动态配置为上行频带和下行频带的一示意图。如图4所示，该传统的FDD上行频带的载频为f2，FDD下行频带的载频为f1，即在任一时刻，该FDD上行频带只能进行上行传输。在被指示信息重新配置之后，该FDD上行频带在任意时刻，均可以进行上行传输和下行传输。至于在某一时刻具体是上行传输还是下行传输，例如可以由调度信息确定。
再例如，当用户设备搜索到一个频带后，确定该频带为非授权频带。此外，基站会发送指示信息来指明该非授权频带可以同时作为上行频带和下行频带。因此，该非 授权频带被动态地重新进行了配置。可选的，该指示信息中可以指定该频带的相关信息，例如载波频率、带宽等。
图5是本发明实施例的非授权频带被动态配置为上行频带和下行频带的一示意图。如图5所示，该传统的非授权频带的载频为f1。在被指示信息重新配置之后，该非授权频带在任意时刻，均可以进行上行传输和下行传输。至于在某一时刻具体是上行传输还是下行传输，例如可以由调度信息确定。
在本实施例中，指示信息可以通过系统消息或特定消息发送给用户设备。对于系统消息，小区内所有能够理解该消息的用户设备可以收到并采用。对于特定消息，基站会通过该消息发送给特定的用户设备，因此只有收到该消息的用户设备才会采用该指示消息。
由此，通过重新配置半双工频带的指示信息；可以支持半双工频带同时被配置成上行频带和下行频带。
在本实施例中，在半双工频带上进行下行服务的传输点不同于进行上行服务的传输点。从一个小区的角度来看，同一小区的多个用户设备中部分用户设备在半双工频带上进行上行传输，同时另一部分用户设备在该半双工频带上进行下行传输；同一小区的多个用户设备中部分用户设备被一个或多个传输点服务，同时另一部分用户设备被一个或多个其他传输点服务。
其中，传输点可以是宏基站，也可以是微基站，还可以是远端无线头(RRH，Remote Radio Head)等，但本发明不限于此。
图6是本发明实施例的同一小区内多个用户设备进行上下行传输的一示意图，如图6所示，在宏基站形成的小区(使用频带f1)内可以有传输点1和传输点2，UE1和传输点1在该频带f1上进行上行传输，而UE2和传输点2在该频带f1上进行下行传输。由此，小区容量不会受到太多限制，并且能够很好地支持上下行容量都比较大的情况。
以下对于用户设备的行为进行进一步说明。
在本实施例中，用户设备还可以接收网络侧设备发送的调度信息，根据该调度信息在该半双工频带进行上行传输或下行传输。
图7是本发明实施例的频带配置方法的另一示意图，示出了在被重新配置的半双工频带上进行调度的情况；如图7所示，所述方法包括：
步骤701，用户设备搜索一半双工频带；
步骤702，用户设备获得该半双工频带的配置信息；
步骤703，用户设备接收网络侧设备发送的用于重新配置该半双工频带的指示信息；其中该指示信息指示该半双工频带既被用于上行传输也被用于下行传输。
步骤704，用户设备接收网络侧设备发送的调度信息；
其中，用户设备可以在该半双工频带上接收该调度信息，或者还可以通过跨载波调度的方式在不同于该半双工频带的其他频带上接收该调度信息。
其中，该调度信息可以包括如下信息的一种或多种：被调度的频带信息、被调度的方向信息(例如上行或者下行)、被调度的时隙信息、被调度的资源信息、调制编码方式信息，等等。
步骤705，用户设备在该半双工频带上根据该调度信息进行上行传输或下行传输。
例如，在某一时隙，用户设备在该半双工频带上被调度的情况下，该用户设备在该时隙根据该调度信息在该半双工频带上进行上行传输或下行传输。
值得注意的是，图7仅示意性地对本发明实施例进行了说明，但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序，此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图的记载。
在本实施例中，在某一时隙，用户设备在该半双工频带上没有被调度的情况下，可以在该时隙根据预定的默认设置在该半双工频带上进行上行传输或下行传输。
例如，如果用户设备在当前时隙内在该频带上没有被调度，则该用户设备就按照默认值处在上行传输状态或下行接收状态。
在本实施例中，在某一时隙，用户设备在该半双工频带上没有被调度的情况下，可以在该时隙根据配置信息在该半双工频带上进行上行传输或下行传输。
例如，如果该频带是TDD频带，用户设备可以按照接收到的TDD配置信息(例如，该TDD配置信息指示了每个时隙的上下行配置)来确定该时隙的上下行配置。如果该频带是FDD下行频带，用户设备可以按照接收到的FDD配置信息来确定在该时隙处在下行接收状态。如果该频带是FDD上行频带，用户设备可以按照接收到的FDD配置信息来确定在该时隙处在上行传输状态。
在本实施例中，用户设备还可以按照FDD模式的时序关系在该半双工频带上进 行上行传输或下行传输。即无论该频带是哪种频带，均按照FDD模式工作。
例如，用户设备遵循FDD模式下的时序关系，如果用户设备在时隙n内被调度为上行或下行，则可以在时隙n+4内反馈ACK/NACK。
由上述实施例可知，用户设备接收网络侧发送的用于重新配置半双工频带的指示信息；其中该指示信息指示该半双工频带既被用于上行传输也被用于下行传输。由此，可以支持半双工频带同时被配置成上行频带和下行频带，小区容量不会受到太多限制，并且能够很好地支持上下行容量都比较大的情况。

如图8所示，所述方法还可以包括：
步骤803，基站向该用户设备发送调度信息，使得该用户设备在该半双工频带上根据该调度信息进行上行传输或下行传输。

由上述实施例可知，网络侧设备发送用于重新配置半双工频带的指示信息；其中该指示信息指示该半双工频带既被用于上行传输也被用于下行传输。由此，可以支持半双工频带同时被配置成上行频带和下行频带，小区容量不会受到太多限制，并且能够很好地支持上下行容量都比较大的情况。
