Description

半双工系统下的子帧调度方法、数据收发方法、装置和系统 技术领域
本发明涉及通信领域，特别涉及一种半双工系统下的子帧调度方法、数据收发方法、装置和系统。
背景技术
超密集网络是5G(第五代移动通信技术)系统的关键技术之一。为了提升系统容量，服务宏小区(macro cell)和/或小小区(small cell)的基站(BS：Base Station)或传输点(TP：Transmission Point)间的协作成为了重要的研究方向。
在现有机制中，每个基站或传输点都按照一个指定的上下行子帧配置与UE通信。该上下行子帧配置由网络(如基站)通过系统信息或物理层的信令来进行配置且被UE(User Equipment，用户设备，简称为用户)所知道，并且在收到新的上下行子帧配置前，该上下行子帧配置不会被改变。也就是说，对于那些收到相同的上下行子帧配置的UE，如果只有部分UE在一个上行或下行子帧被调度，其他没有被调度的UE就不能在该子帧内得到服务，例如被其他的基站或传输点服务。这样就限制了系统容量的提升。
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。
发明内容
在现有的机制中，在收到新的上下行子帧配置前，UE只能按照当前的上下行子帧配置被调度。该方法实现起来比较简单，UE可以根据收到的上下行子帧配置来确定相关操作(如HARQ：Hybrid Automatic Repeat Request，混合自动重传请求)的时序。但是因为在上下行子帧配置固定的情况下，上行子帧只能调度上行数据，下行子帧只能调度下行数据，限制了系统容量的提升。

具体实施方式
参照附图，通过下面的说明书，本发明的前述以及其它特征将变得明显。在说明书和附图中，具体公开了本发明的特定实施方式，其表明了其中可以采用本发明的原则的部分实施方式，应了解的是，本发明不限于所描述的实施方式，相反，本发明包括落入所附权利要求的范围内的全部修改、变型以及等同物。下面结合附图对本发明的各种实施方式进行说明。这些实施方式只是示例性的，不是对本发明的限制。
本发明实施例的应用场景为半双工系统，也即，在任何时刻，每个传输点在一个载波上只能工作在上行或下行。考虑的场景是一个物理区域由多个传输点覆盖，每个传输点有一根或多根天线。如图1所示，每个传输点可以是一个基站且形成了工作在某个载波上的物理小区。或者，如图2和图3所示，多个传输点同时连接到一个BBU pool(Base band Unit pool，基带单元池)并形成了工作在某个载波上的一个物理小区(图2)或者多个物理小区(图3)。
在上述场景中，每个传输点可以以相同的或不同的上下行子帧配置工作。每个用户被配置了某个传输点的上下行子帧配置。这个配置定义了一个周期性的上下行子帧设置，在LTE(Long Term Evolution，长期演进)系统中，这个周期是10个子帧，即10ms，并且这个设置在一定时间内不会发生改变，如500ms。在LTE系统中，这个上下行子帧配置就是系统消息或下行控制信息(DCI：Downlink Control Information)中指定的TDD(Time Division Duplexing，时分双工)配置。为了方便说明，在本实施例中，将该配置称为第一上下行子帧配置。
实施例1
本发明实施例提供了一种半双工系统下的子帧调度方法，图4是该方法的流程图，请参照图4，该方法包括：
步骤401：网络侧向用户设备发送上下行子帧改变信息，通过所述上下行子帧改变信息指示所述用户设备改变所述网络侧的第一上下行子帧配置中的一个子帧或一组子帧的上下行设置；
步骤402：所述网络侧按照改变后的上下行设置在相应的子帧为所述用户设备服务。
在步骤401中，网络侧在改变其第一上下行子帧配置前(也即，用户设备在收到新的第一上下行子帧配置前)，对于一个上下行子帧或者一组上下行子帧，网络侧在该子帧或该组子帧开始前，向用户设备发送一个上下行子帧改变信息，来指示该用户设备改变该网络侧的第一上下行子帧配置中的该子帧或该组子帧的上下行设置，例如，如果该子帧或该组子帧为上行子帧，则将其改变为下行子帧，也即在该子帧或该组子帧上接收数据；反之，如果该子帧或该组子帧为下行子帧，则将其改变为上行子帧，也即，在该子帧或该组子帧上发送数据。
其中，该上下行子帧改变信息可以通过物理控制信道发送，例如PDCCH(Physical Downlink Control Channel，物理下行控制信道)，也可以通过其它消息发送，例如MAC(Media Access Control，媒体访问控制)层控制元素(control element)等。
其中，该网络侧的实体可以是基站(BS：Base Station)，也可以是其它具有控制功能的传输点(TP：Transmission Point)，本实施例并不以此作为限制。
在本实施例的一个实施方式中，该上下行子帧改变信息可以包含被改变上下行设置的子帧的位置信息。由此，用户设备可以确定该网络侧的第一上下行子帧配置中改 变了上下行配置的子帧或子帧组，从而根据改变后的上下行配置，在该子帧或子帧组上接收或发送数据。
其中，考虑到子帧是由序号表示，该位置信息可以通过子帧序号来指示，例如，如果该上下行子帧改变信息中包含序号5，则表示改变第5个子帧的上下行设置，或者如果该上下行子帧改变信息中包含一个序号范围(如3～6)或一组序号(如3，4，5，6)，则表示改变第3，4，5，6个子帧的上下行设置。
其中，该位置信息也可以通过位图(bitmap)的形式来指示，例如，如果该上下行子帧改变信息中包含bitmap“0100100110”，则表示改变第2，第5，第8和第9个子帧的上下行设置。
在本实施例的另一个实施方式中，该上下行子帧改变信息不包含上述位置信息，则表示被改变上下行设置的子帧与接收所述上下行子帧改变信息的子帧具有固定的时序关系。由此，用户设备可以根据该固定的时序关系确定该网络侧的第一上下行子帧配置中改变了上下行设置的子帧或子帧组，从而根据改变后的上下行配置，在该子帧或子帧组上接收或发送数据。
其中，例如，如果UE在第n个子帧接收到上下行子帧改变信息，则表示改变第n+m子帧或从第n+m子帧到第n+m+k子帧的上下行设置。这个固定的时序关系，也即该m以及该k的值可以预定义好或预配置好。其中，预定义是指由标准预先定义，网络侧和用户设备都知道的，预配置是指网络侧预先配置并通知用户设备的。
在本实施例的一个实施方式中，可选的，该上下行子帧改变信息还可以包含与被改变上下行设置的子帧相关的调度信息，例如分配给用户设备的资源的位置、调制编码方式、功率控制参数等等。由此，用户设备可以直接根据该调度信息在该改变了上下行设置的子帧上接收数据或发送数据。
图5是改变网络侧的第一上下行子帧配置中的子帧的上下行设置的一个示例的示意图，如图5所示，(a)为网络侧的第一上下行子帧配置的示意图；(b)为将第8个子帧的上下行方向由上行改为下行的示意图，也即在该示例中，第8个子帧由上行子帧改变为下行子帧；(c)为将第9个子帧的上下行方向由下行改为上行的示意图，也即在该示例中，第9个子帧由下行子帧改变为上行子帧。
在步骤402中，网络侧可以选择另外一个传输点按照改变后的上下行设置在相应的子帧为该用户设备服务，也可以自己按照改变后的上下行设置在相应的子帧为该用 户设备服务。下面通过举例进行说明。
图6是本实施例的另一个应用场景的示意图，如图6所示，两个用户(UE1和UE2)同在TP1和TP2的覆盖范围内。TP2按照图6所示的上下行子帧配置工作。假设UE2接收到一个上下行子帧改变信息，该信息指示将第8个子帧由上行改变为下行，则根据本实施例的方法，网络侧(TP2)可以有以下两种处理方式。
方式一，网络侧(TP2)在第8子帧选择TP1服务UE2的下行，同时TP2在第8子帧服务UE1的上行。由此，在TP2的覆盖范围内会出现在同一个子帧，两个不同的用户分别以上行和下行两种不同的方式同时工作的情况，从而实现了在这个小范围内的一个全双工的通信，提升了系统容量。
方式二，网络侧(TP2)在第8子帧服务UE2的下行，而不是其上下行子帧配置中指定的上行。由此，TP2可以在第8个子帧调度UE2的下行，提升了系统容量。
实施例2
本发明实施例还提供了一种半双工系统下的子帧调度方法，图7是该方法的流程图，请参照图7，该方法包括：
步骤701：网络侧向用户设备发送上下行可变子帧指示信息，通过所述指示信息指示所述网络侧的第一上下行子帧配置中可以改变上下行设置的子帧或子帧组；
步骤702：所述网络侧按照改变后的上下行设置在相应的子帧为所述用户设备服务。
在步骤701中，网络侧可以通过向用户设备发送一个指示上下行可变子帧的信息来指明第一上下行子帧配置中哪个或哪组子帧可以改变上下行设置，这类子帧可以称为上下行可变子帧。
其中，该指示信息可以通过系统消息，RRC(Radio Resource Control，无线资源控制协议)消息，MAC层控制元素或物理层信令(如下行控制信息)等发送。
在本实施例中，该指示信息可以通过如下方式来指示上下行可变子帧的位置，但本实施例并不以此作为限制。例如，通过上下行可变子帧的序号来指示；或者，通过表明上下行可变子帧的位置的位图(bitmap)来指示，如一个bitmap“0100100110”，则表示可以改变第2，第5，第8和第9个子帧的上下行设置；或者，通过配置一个不同于第一上下行子帧配置的上下行子帧配置来指示，也即，通过与所述网络侧的第一上下行子帧配置不同的上下行子帧配置来指示，由此，用户设备可以根据该不同， 认为那些在这两种配置中有着不同上下行设定的子帧就是上下行可变子帧；或者，通过预定义或预配置的方式来指示，也即将第一上下行子帧配置中预定义或预配置的子帧指示为上下行可变子帧。其中，预定义和预配置的方式与实施例1类似，在此不再赘述。
在本实施例中，该网络侧的实体可以是基站(BS：Base Station)，也可以是其它具有控制功能的传输点(TP：Transmission Point)，本实施例并不以此作为限制。
在本实施例的一个实施方式中，除了通过上述指示信息来指示上下行可变子帧以外，该网络侧还可以向用户设备发送上下行子帧改变信息，通过该上下行子帧改变信息指示该用户设备改变该网络侧的第一上下行子帧配置中一个子帧或一组子帧的上下行设置。
其中，对于该上下行子帧改变信息与实施例1相同，其内容被合并于此，在此不再赘述。
通过本实施例的方法，用户设备在接收到该指示信息后，可以确定可以改变上下行配置的子帧或子帧组(上下行可变子帧)，如果进一步接收到上述上下行子帧改变信息，则可以根据该上下行子帧改变信息进一步确定要改变哪个或哪些子帧的上下行设置；如果没有接收到上述上下行子帧改变信息，则可以根据预定策略决定是否改变该上下行可变子帧的上下行设置以及如何改变，具体将在以下进行说明。由此，如前所述，由于可以由同一个TP或不同的TP在同一个子帧调度不同用户的上下行传输，提升了系统容量。
实施例3
本实施例还提供了一种半双工系统下的数据收发方法，该方法是对应实施例1和实施例2的方法的用户设备侧的处理，图8是该方法的流程图，请参照图8，该方法包括：
步骤801：用户设备根据接收到的上下行子帧改变信息和/或上下行可变子帧指示信息确定网络侧的第一上下行子帧配置中被改变上下行设置的子帧或子帧组；
步骤802：所述用户设备根据改变了上下行设置的子帧或子帧组收发数据。
在本实施例中，如前所述，网络侧可能下发上下行子帧改变信息和/或上下行可变子帧指示信息，则在步骤801中，用户设备可以根据接收到的信息确定要改变上下行设置的子帧或子帧组。其中，上下行子帧改变信息和上下行可变子帧指示信息已经 分别在实施例1和实施例2中做了详细说明，其内容被合并于此，在此不再赘述。
在本实施例的一个实施方式中，如果该用户设备接收到上述上下行子帧改变信息，且该上下行子帧改变信息包含被改变上下行设置的子帧的位置信息，则该用户设备可以根据该位置信息确定网络侧的第一上下行子帧配置中被改变上下行设置的子帧或子帧组。
在本实施例的另一个实施方式中，如果该用户设备接收到上述上下行子帧改变信息，且该上下行子帧改变信息不包含被改变上下行设置的子帧的位置信息，则如前所述，由此表明被改变上下行设置的子帧与接收该上下行子帧改变信息的子帧之间具有固定的时序关系，则该用户设备可以根据该固定的时序关系确定网络侧的第一上下行子帧配置中被改变上下行设置的子帧或子帧组。
在本实施例的另一个实施方式中，如果该用户设备接收到上述上下行可变子帧指示信息，而没有接收到上述上下行子帧改变信息，则该用户设备可以确定该上下行可变子帧为默认的上下行设置。例如，与所述网络侧的第一上下行子帧配置一致，也即保持不变；或者都是上行子帧；或者都是下行子帧。
在本实施例的另一个实施方式中，如果该用户设备接收到上述上下行子帧改变信息和上述上下行可变子帧指示信息，则该用户设备可以确定该上下行可变子帧中由该上下行子帧改变信息所指定的子帧的上下行设置改变。其中，如果该上下行可变子帧中还有该上下行子帧改变信息没有指定的子帧，则该用户设备可以确定该没有被指定的子帧为默认的上下行设置。例如，与所述网络侧的第一上下行子帧配置一致；或者都是上行子帧；或者都是下行子帧。
以图5所示的上下行子帧配置(a)为例，如果上下行可变子帧指示信息所指示的上下行可变子帧为第8～10个子帧(也即，在该上下行子帧配置(a)中，可以改变第8～10个子帧的上下行设置)，而上下行子帧改变信息所指示的改变上下行设置的子帧为第8个子帧，则在该上下行子帧配置(a)中，第8个子帧由上行改为下行，而剩下的第9、10个子帧可以保持其原有配置，也即都为下行子帧，也可以都是上行子帧，或者都是下行子帧。
通过本实施例的方法，按照网络侧下发的信息改变子帧的上下行设置，如前所述，可以提升系统容量。
