本发明涉及通信领域，特别涉及一种资源重叠的检测和处理方法、装置和系统。
背景技术
在5G网络中，为了提高系统容量，一个终端(UE，User Equipment)可能会被多个传输点(Transmission point：TP)服务。由于这些传输点离用户的距离不一样，而且发送数据的时钟不同，会导致与用户通信时的时钟不同步。因此，有可能当终端在向一个传输点发送数据或从一个传输点接收数据时，另一个传输点已经开始向该终端发送数据或准备接收该终端发送的数据。这样就会导致用户数据的丢失，损失终端性能。

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。
在本发明实施例中，为了方便说明，以终端被两个传输点服务为例，每个传输点可能是一个独立的基站，也可能是连接到同一个虚拟基站池的传输节点。这两个传输点可能覆盖具有不同小区ID的不同小区，也可能覆盖具有相同小区ID的不同小区。
在本发明实施例中，传输点的时钟参考点表示当终端接收传输点的数据时，时隙n的起始时刻。例如，如图1所示，如果终端要在时隙n接收传输点的下行数据，传输点对于时隙n的时钟参考点就是T。
在本发明实施例中，上行传输的时间提前量表示如果终端在时隙n发送上行数据，其需要相对于传输点在时隙n的时钟参考点提前该提前量所指示的时间长度来发送上行数据。例如，如图2所示，如果传输点在时隙n的时钟参考点为T，终端需要在T-TA时刻开始发送上行数据。
因为两个传输点的时钟不同步，终端在时隙n-1与一个传输点通信的资源会与在时隙n与另一个传输点通信的资源重合。具体的包括下述的四种情况，如图3-图6所示，其中，T1和T2分别表示TP1和TP2在时隙n的时钟参考点，即终端需要从T1开始接收TP1在时隙n发送给终端的数据，同理，终端需要从T2开始接收TP2在时隙n发送给终端的数据；TA1和TA2分别表示如果终端需要向TP1或TP2发送上行数据，其相对于时钟参考点的发送提前量。在图3-图6中，时隙的编号是针对终端来说的。
如图3所示，终端在时隙n-1接收TP1的下行数据，然后，在时隙n接收TP2的下行数据。但是，在时隙n，TP2的时钟参考点比TP1的时钟参考点提前，即针对时隙n，T1>T2(T1-T2>0)。因此，终端不能在阴影区内同时收两个TP的数据。
如图4所示，终端在时隙n-1接收TP1的下行数据，然后，在时隙n向TP2发送上行数据。但是，上行发送的起始时间早于终端在时隙n-1接收TP1的下行数据的结束时间，即T2-TA2<T1(T1-T2>-TA2)。因此，终端只能在阴影区内要么接收TP1的下行数据，要么向TP2发送上行数据。
如图5所示，终端在时隙n-1内向TP1发送上行数据，然后，在时隙n内接收TP2的下行数据。但是，接收TP2的下行数据的起始时间早于在时隙n-1内向TP1发送上行数据的结束时间，即T2<T1-TA1(T1-T2>TA1)。因此，终端在阴影区内要么接收TP2的下行数据，要么向TP1发送上行数据。
如图6所示，终端在时隙n-1内向TP1发送上行数据，然后，在时隙n内向TP2发送上行数据。但是在时隙n向TP2发送上行数据的起始时间早于在时隙n-1内向TP1发送上行数据的结束时间，即T2-TA2<T1-TA1(T1-T2>TA1-TA2)。因此，终端不能在阴影区域内同时向TP1和TP2发送上行数据。
为了解决图3-图6的资源重叠的问题，本发明实施例提出了一种资源重叠的检测和处理方法、装置和系统，下面结合附图对本发明实施例的方法、装置和系统进行说明。然而，本领域技术人员可以清楚，本实施例并不限于图3-图6所示的场景，也适用于其它场景下关于资源重叠的检测和处理。
实施例1

在该例子中，如果TP1和TP2知道各自的TA1和TA2，则该发送单元701可以向TP1发送T1和T2或者T1-T2/T2-T1，然后TP1可以将从该终端接收到的上述信息连同自己的TA1发送给TP2。可选的，TP2还可以将自己的TA2发送给TP1。类似的，该发送单元701可以向TP2发送T1和T2，或者发送T1-T2/T2-T1，然后TP2可以将从该终端接收到的上述信息连同自己的TA2发送给TP1。可选的，TP1也可以将自己的TA1发送给TP2。
在该例子中，如果TP1和TP2不知道各自的TA1和TA2，则该发送单元701可以向TP1发送T1和T2或者T1-T2/T2-T1，以及TA1和/或TA2，然后TP1可以将从该终端接收到的上述信息发送给TP2。类似的，该发送单元701可以向TP2发送T1和T2或者T1-T2/T2-T1，以及TA1和/或TA2，然后TP2可以将从该终端接收到的上述信息发送给TP1。
在该实施方式中，为所述终端服务的所有传输点的时钟参考点之差是指该所有传输点中任意两个传输点的时钟参考点之差，以该终端被三个传输点TP1、TP2、以及TP3服务为例，该所有传输点的时钟参考点之差是指T1-T2/T2-T1，T1-T3/T3-T1，以及T2-T3/T3-T2。类似的，为所述终端服务的部分传输点的时钟参考点之差是指该部分传输点中任意两个传输点的时钟参考点之差，仍以该终端被三个传输点服务为例，该部分传输点的时钟参考点之差是指T1-T2/T2-T1和T1-T3/T3-T1，或者T1-T3/T3-T1和T2-T3/T3-T2，或者T1-T2/T2-T1和T2-T3/T3-T2。
在另一个实施方式中，该发送单元701向为该终端服务的所有传输点发送上述时间参考信息。在该实施方式中，向一个传输点发送的时间参考信息可以包括以下信息的任意一种：为所述终端服务的所有或部分传输点的时钟参考点以及上行传输时间提前量；或者，为所述终端服务的所有或部分传输点的上行传输时间提前量；或者，为所述终端服务的所有或部分传输点的时钟参考点之差以及上行传输时间提前量。
在该实施方式中，时钟参考点之差的概念与前述相同，此处不再赘述。
仍以该终端UE被两个传输点TP1和TP2服务为例。
在该例子中，如果TP1和TP2知道各自的TA1和TA2，则发送单元701可以向TP1发送T1和T2或者T1-T2/T2-T1，以及TA2，并且向TP2发送T1和T2或者T1-T2/T2-T1，以及TA1。
在该例子中，如果TP1和TP2不知道各自的TA1和TA2，则发送单元701可以向TP1和TP2发送T1和T2或者T1-T2/T2-T1，以及TA1和/或TA2。
在本实施例中，该时间参考信息中所包含的时钟参考点或者上行传输的时间提前量或者时钟参考点之差所对应的时隙可以通过该时间参考信息中的时隙指示信息来指示，也可以是预先约定的，还可以有其它指示方式，本实施例并不以此作为限制。
通过本实施例的装置，在一个终端被多个传输点服务时，将与该多个传输点有关的时间参考信息发送给某个或某些传输点，以便各传输点检测其为终端分配的资源是 否与其它传输点为该终端分配的资源存在重叠，以采取适当的措施避免该重叠，由此解决了背景技术指出的问题。

在该实施方式中，该时钟参考点或者该时钟参考点之差可以是终端发送的，如实施例1所述，也可以是该传输点已知的，例如为该终端服务的所有传输点都已知自己的时钟参考点，通过传输点之间的信息交互，各个传输点可以得到所有传输点的时钟参考点或者时钟参考点之差。由此，该传输点可以通过上述第一判断模块8011和第一确定模块8012判断自己为该终端分配的资源是否与其它传输点为该终端分配的资源存在重叠。
以图3所示的场景为例，如果第一判断模块8011判断为T1＞T2，或者T1-T2＝0，则第一确定模块8012确定为存在资源重叠。
在另一个实施方式中，该时间参考信息包括：为所述终端服务的所有传输点的时钟参考点或者所有传输点的时钟参考点之差，以及所述传输点(如图5所示的TP1)的上行传输的时间提前量，则在本实施方式中，如图8所示，该检测单元801可以包括第二判断模块8013和第二确定模块8014。
在本实施方式中，该第二判断模块8013针对同一个时隙(如图5所示的时隙n)， 判断是否其它传输点(如图5所示的TP2)的时钟参考点比所述传输点(如图5所示的TP1)的上行发送时间提前；该第二确定模块8014在第二判断模块8013判断为是时，确定所述传输点为所述终端分配的资源与其它传输点为所述终端分配的资源存在重叠。
在本实施方式中，与前一实施方式类似，上述时钟参考点或者上述时钟参考点之差可以是该终端发送的，也可以是各传输点已知并通过信息交互确定的，此处不再赘述。
在本实施方式中，该传输点的上行传输的时间提前量可以是该传输点已知的，也可以是终端发送的，还可以是其它传输点发送的，如实施例1所述。由此，该传输点可以通过上述第二判断模块8013和第二确定模块8014进一步判断出自己为终端分配的资源是否与其它传输点为该终端分配的资源存在重叠。
以图5所示的场景为例，如果第二判断模块8013判断为T2＜T1-TA1，也即T2-T1＜-TA1，或者T1-T2＞TA1，则第二确定模块8014确定为存在资源重叠。
在再一个实施方式中，该时间参考信息包括：为所述终端服务的所有传输点的时钟参考点或者所有传输点的时钟参考点之差，以及其它传输点(例如图4所示的TP2)的上行传输的时间提前量，则在本实施方式中，如图8所示，该检测单元801可以包括第三判断模块8015和第三确定模块8016。
在本实施方式中，该第三判断模块8015针对同一个时隙(例如图4所示的时隙n)，判断是否其它传输点(例如图4所示的TP2)的上行发送时间点比所述传输点(例如图4所示的TP1)的时钟参考点提前；该第三确定模块8016在第三判断模块8015判断为是时，确定所述传输点为所述终端分配的资源与其它传输点为所述终端分配的资源存在重叠。
在本实施方式中，与前一实施方式类似，上述时钟参考点或者上述时钟参考点之差可以是该终端发送的，也可以是各传输点已知并通过信息交互确定的，此处不再赘述。
在本实施方式中，该其它传输点的上行传输的时间提前量可以是该其它传输点发送的，也可以是上述终端发送的，如实施例1所述。由此，该传输点可以通过上述第三判断模块8015和第三确定模块8016进一步判断出自己为终端分配的资源是否与其它传输点为该终端分配的资源存在重叠。
以图4所示的场景为例，如果第三判断模块8015判断为T2-TA2＜T1，也即T2-T1＜TA2，或者T1-T2＞-TA2，则第三确定模块8016确定为存在资源重叠。
在又一个实施方式中，该时间参考信息包括：为所述终端服务的所有传输点的时钟参考点或者所有传输点的时钟参考点之差，以及所有传输点的上行传输的时间提前量，则在本实施方式中，如图8所示，该检测单元801可以包括第四判断模块8017和第四确定模块8018。
在本实施方式中，该第四判断模块8017针对同一个时隙(例如图6所示的时隙n)，判断是否其它传输点(例如图6所示的TP2)的上行发送时间比所述传输点(例如图6所示的TP1)的上行发送时间提前；该第四确定模块8018在第四判断模块8017判断为是时，确定所述传输点为所述终端分配的资源与其它传输点为所述终端分配的资源存在重叠。
在本实施方式中，与前一实施方式类似，上述时钟参考点或者上述时钟参考点之差可以是该终端发送的，也可以是各传输点已知并通过信息交互确定的，此处不再赘述。
在本实施方式中，所有传输点的上行传输的时间提前量中，所述传输点的上行传输的时间提前量可以是所述传输点已知的，也可以是上述终端发送的，其它传输点的上行传输的时间提前量可以是该其它传输点发送的，也可以是上述终端发送的，如实施例1所述。由此，该传输点可以通过上述第四判断模块8017和第四确定模块8018进一步判断出自己为终端分配的资源是否与其它传输点为该终端分配的资源存在重叠。
以图6所示的场景为例，如果第四判断模块8017判断为T2-TA2＜T1-TA1，也即T2-T1＜TA2-TA1，或者T1-T2＞TA1-TA2，则第四确定模块8018确定为存在资源重叠。
在本实施例中，上述四个实施方式可以合并也可以任意组合，并不限于图8所示的组成。
在本实施例中，与实施例1类似，该时间参考信息中所包含的时钟参考点或者上行传输的时间提前量或者时钟参考点之差所对应的时隙可以通过该时间参考信息中的时隙指示信息来指示，也可以是预先约定的，还可以有其它指示方式，本实施例并不以此作为限制。
通过本实施例的装置，各传输点可以根据时间参考信息检测其为终端分配的资源是否与其它传输点为该终端分配的资源存在重叠，以便采取适当的措施避免该重叠，由此解决了背景技术指出的问题。
实施例3
本发明实施例提供了一种资源重叠的处理装置，应用于传输点，传输点的概念如前所述，此处不再赘述。图9是该装置的组成示意图，如图9所示，该装置900包括：发送单元901，其向其它传输点或终端发送指示信息，所述指示信息用于指示所述传输点为所述终端分配的资源与所述其它传输点为所述终端分配的资源存在重叠，和/或重叠的资源的调度方式(分配方式)。
在本实施例中，所述传输点和所述其它传输点共同为所述终端提供服务。
在发送单元901的一个实施方式中，当传输点检测到其为终端分配的资源与其它传输点为该终端分配的资源存在重叠时，该传输点通过上述指示信息告知该其它传输点或者该终端这一情况，由此，该其它传输点或者该终端可以据此采取相应的规避措施。
在发送单元901的另一个实施方式中，当传输点检测到其为终端分配的资源与其它传输点为该终端分配的资源存在重叠时，该传输点通过上述指示信息将重叠的资源的调度方式(分配方式)告知该其它传输点或者该终端，由此，该其它传输点或者该终端可以据此采取相应的规避措施。
例如，该指示信息可以指示以下内容：所述传输点或所述其它传输点不在重叠的时隙调度同一个终端。
仍以一个终端被两个传输点TP1和TP2提供服务为例，在本实施方式中，TP1可以向TP2发送指示信息表明TP1在时隙n-1内不调度该终端，或者指示信息建议TP2在时隙n内不调度该终端。相应的，TP1还可以向该终端发送指示信息表明终端不会在时隙n-1被TP1调度，或者向该终端发送指示信息表明终端不会在时隙n内被TP2调度。
类似的，TP2可以向TP1发送指示信息表明TP2在时隙n内不调度该终端，或者指示信息建议TP1在时隙n-1内不调度该终端。相应的，TP2还可以向该终端发送指示信息表明终端不会在时隙n内被TP2调度，或者向该终端发送指示信息表明终 端不会在时隙n-1内被TP1调度。
在这里例子中，可以通过设置各传输点的优先级来默认由哪个传输点不在重叠的时隙调度该终端，例如，优先级低的传输点不在重叠的时隙调度该终端。
再例如，该指示信息可以指示以下内容：所述传输点或所述其它传输点会提前或推迟预定时间来调度同一个终端在重叠的时隙与所述传输点或所述其它传输点通信。
仍以一个终端被两个传输点TP1和TP2提供服务为例，在该实施方式中，TP1可以向TP2发送指示信息表明TP1会提前t时间来调度该终端在时隙n-1内与TP1通信，或者发送指示消息建议TP2推迟t时间来调度该终端在时隙n内与TP2通信。相应的，TP1或TP2可以向该终端发送相应的信息来表明这种行为。
类似的，TP2可以向TP1发送指示信息表明TP2会推迟t时间来调度用户在时隙n内与TP2通信，或者发送指示信息建议TP1提前t时间来调度用户在时隙n-1内与TP1通信。相应的，TP1或TP2可以向该终端发送相应的信息来表明这种行为。
在这个例子中，可以通过改变上行传输和下行传输转换时的保护时间(GT：Guard Time)的长度来实现上述提前/推迟，也可以通过预设固定的时间长度来实现上述提前/推迟，本实施例并不以此作为限制。
在这个例子中，可以通过设置各传输点的优先级来默认由哪个传输点提前或推迟上述预定时间来调度终端，例如，优先级低的传输点推迟上述预定时间。
再例如，该指示信息可以指示以下内容：所述传输点或所述其它传输点不在重叠的时隙的重合区域为同一个终端分配资源。由此，该终端可以在整个重叠时隙内与所述其它传输点或者所述传输点通信。
仍以一个终端被两个传输点TP1和TP2提供服务为例，在该实施方式中，TP1可以向TP2发送指示信息表明TP1不会在时隙n-1内的某些资源位置为该终端分配资源，或者发送指示信息建议TP2在整个时隙n内为该终端分配资源，由此该终端可以在整个时隙n与TP2通信。相应的，TP1或TP2可以向终端发送指示信息表明终端可以在整个时隙n内与TP2通信，或发送指示信息表明TP1不会在时隙n-1内的某些区域为该终端分配资源，进而终端不在该区域内与TP1通信。
类似的，TP2可以向TP1发送指示信息表明TP2不会在时隙n内的某些资源位置为终端分配资源，或者发送指示信息建议TP1可以在整个时隙n-1内为该终端分配资源，由此该终端可以在整个时隙n-1与TP1通信。相应的，TP1或TP2可以向终端 发送指示信息表明终端会在整个时隙n-1内与TP1通信，或发送指示信息表明TP2不会在时隙n内的某些区域为该终端分配资源，进而终端不在该区域内与TP2通信。
在本实施方式中，如果所述传输点和所述其它传输点在重叠的资源同时服务于该终端的下行，则上述指示信息可以指示以下内容：所述传输点和所述其它传输点为所述终端发送了相同或不同的数据。
仍以一个终端被两个传输点TP1和TP2提供服务为例，如果TP1和TP2在重叠的资源同时服务于该终端的下行，则这两个传输点可以向该终端发送相同或不同的数据，这些数据可以叠加到该重叠的资源上传输，并通过不同的发送功率来区分，本实施例并不以此作为限制。在这个例子中，TP1或TP2可以通过向TP2或TP1发送上述指示信息来表明这一行为。在这个例子中，TP1或TP2还可以向该终端发送上述指示信息来表明这一行为。
在本实施方式中，如果所述传输点和所述其它传输点在重叠的资源同时服务于同一个终端的上行，则上述指示信息可以指示以下内容：所述终端可以同时向所述传输点和所述其它传输点发送相同或不同的数据。
与上一个例子类似，如果TP1和TP2在重叠的资源同时服务于该终端的上行，则该终端可以同时向这两个传输点发送相同或不同的数据，这些数据可以叠加到该重叠的资源上传输，并通过不同的发送功率来区分，本实施例并不以此作为限制。在这个例子中，类似的，TP1或TP2可以通过向TP2或TP1发送上述指示信息来表明这一行为，并且TP1或TP2还可以向该终端发送上述指示信息来表明这一行为。
以上通过不同的实施方式和例子对存在资源重叠时各传输点采取的措施做了说明，然而本实施例并不以此作为限制，只要传输点能够通过发送上述指示信息来表明这种重叠和/或规避这种重叠，都包含于本申请的保护范围。
在本实施例中，传输点用于检测资源重叠的方法包括但不限于本发明实施例2所提供的方法。
在一个实施方式中，如图9所示，该装置还可以包括：检测单元902，其检测所述传输点为所述终端分配的资源是否与其它传输点为所述终端分配的资源存在重叠。
在检测单元902的一个实施方式中，该检测单元902可以根据时间参考信息来进行上述检测。关于时间参考信息以及检测的方式，已经在实施例2中做了说明，其内容被合并于此，此处不再赘述。
在检测单元902的其它实施方式中，该检测单元902也可以根据其它信息来进行上述检测，此处不再赘述。
通过本实施例的装置，在检测到资源重叠时，传输点可以采取适当的措施来避免该重叠，由此解决了背景技术指出的问题。

在本实施例中，该终端被上述传输点和上述其它传输点共同服务。
在本实施例中，通过上述指示信息，该传输点可以知道在哪些时隙存在资源重叠，和/或，重叠的资源的调度方式(分配方式)，由此，该传输点可以采取相应的措施来避免重叠，例如不在重叠的时隙调度该终端，或者在重叠的时隙提前/推迟预定时间调度该终端，或者不在重叠的时隙的重合区域调度终端等。由此，避免了由于资源重叠导致的性能损失。
