Abstract

一种动态时分双工的设置装置、方法以及通信***。所述设置方法包括：网络设备接收一个或多个用户设备在接收信号的强度大于第一阈值和/或跨链路干扰的强度小于第二阈值的情况下发送的强度指示信息；根据强度指示信息将服务小区内一个或多个用户设备配置为使用动态时分双工。由此，相邻小区进行动态TDD的用户设备之间距离较大，从而可以有效地抑制动态TDD***的跨链路干扰。

Description

动态时分双工的设置装置、方法以及通信*** 技术领域
本发明实施例涉及通信技术领域，特别涉及一种动态时分双工(TDD，Time Division Duplex)的设置装置、方法以及通信***。
背景技术
在新无线(NR，New Radio)***中，动态TDD支持以一个时间单元(例如一个时隙(slot))为基本单元动态地分配数据传输的上下行配置，因此每个网络设备(例如gNB)与用户设备之间的传输方向可能以一个时间单元(例如一个时隙)为基本单元而动态改变。
图1是动态TDD的传输方向的一示意图，如图1所示，在某一个时间单元(例如第1个时隙)网络设备的数据传输方向为下行(DL，Downlink)，在下一时间单元(例如第2个时隙)网络设备的数据传输方向可能变为上行(UL，Uplink)。
NR***中如果采用动态TDD，则需要频繁地改变数据传输方向，这可能导致相邻小区间严重的跨链路干扰(CLI，Cross-Link Interference)。
图2是NR***中采用动态TDD的一示意图，如图2所示，例如在某一时隙，网络设备gNB1采用动态TDD向本小区(小区1)的用户设备UE1发送下行数据，服务小区(小区2)的用户设备2采用动态TDD向网络设备gNB2发送上行数据；UE1和UE2之间可能产生跨链路干扰，gNB1和gNB2之间也可能产生跨链路干扰。
为了降低跨链路干扰，网络设备之间可以相互协调。例如，如果gNB2知道gNB1在该时隙与UE1之间的传输方向为下行，则可以在该时隙将gNB2与UE2之间的传输方向也调度为下行或者不进行传输数据，从而降低跨链路干扰。
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
但是，发明人发现：在网络设备之间进行协调需要很大的开销；并且还受限于网 络设备间的回路(backhaul)的时延。
例如，采用动态TDD时，某一时隙的上下行传输方向在该时隙的前一个或几个符号(或者该时隙的前一时隙)才被网络设备配置。如果采用传统的通过backhaul来交换这些信息(例如传输方向信息)，则由于非理想backhaul的时延比较大，这些信息很难在短时间内通知给邻居网络设备。
本发明实施例提供一种动态时分双工的设置装置、方法以及通信***。可以半静态地将小区划分为动态TDD区域和静态TDD区域，从而有效地抑制动态TDD***的跨链路干扰。
根据本发明实施例的第一个方面，提供一种动态时分双工的设置方法，包括：
网络设备接收一个或多个用户设备在接收信号的强度大于第一阈值和/或跨链路干扰的强度小于第二阈值的情况下发送的强度指示信息；
所述网络设备根据所述强度指示信息将服务小区内一个或多个用户设备配置为使用动态时分双工。
根据本发明实施例的第二个方面，提供一种动态时分双工的设置装置，包括：
强度指示接收单元，其接收一个或多个用户设备在接收信号的强度大于第一阈值和/或跨链路干扰的强度小于第二阈值的情况下发送的强度指示信息；
资源配置单元，其根据所述强度指示信息将服务小区内一个或多个用户设备配置为使用动态时分双工。
根据本发明实施例的第三个方面，提供一种动态时分双工的设置方法，包括：
用户设备进行跨链路干扰的测量和/或接收信号的测量；
所述用户设备在接收信号的强度大于第一阈值和/或跨链路干扰的强度小于第二阈值的情况下，向网络设备发送强度指示信息；以及
用户设备确定被所述网络设备配置为使用动态时分双工进行数据传输。
根据本发明实施例的第四个方面，提供一种动态时分双工的设置装置，包括：
测量单元，其进行跨链路干扰的测量和/或接收信号的测量；
强度指示发送单元，其在接收信号的强度大于第一阈值和/或跨链路干扰的强度小于第二阈值的情况下，向网络设备发送强度指示信息；以及
资源确定单元，其确定被所述网络设备配置为使用动态时分双工进行数据传输。
根据本发明实施例的第五个方面，提供一种通信***，包括：
网络设备，其包括如上第二方面所述的动态时分双工的设置装置；
用户设备，其包括如上第四方面所述的动态时分双工的设置装置。
本发明实施例的有益效果在于：根据强度指示信息配置使用动态TDD的用户设备，可以半静态地划分动态TDD区域，不同的动态TDD区域被隔离开；由此相邻小区进行动态TDD的用户设备之间距离较大，从而可以有效地抑制动态TDD***的跨链路干扰。

以下将以gNB和UE为例对本发明实施例进行详细说明。
实施例1
本发明实施例提供一种动态TDD的设置方法，应用于网络设备。图4是本发明实施例的动态TDD的设置方法的一示意图，如图4所示，所述设置方法包括：
步骤401，网络设备接收一个或多个用户设备在接收信号的强度大于第一阈值和/或跨链路干扰的强度小于第二阈值的情况下发送的强度指示信息；
步骤402，网络设备根据强度指示信息将服务小区内一个或多个用户设备配置为使用动态TDD。
在本实施例中，所述服务小区内使用所述动态TDD的一个或多个用户设备所形成的区域称为动态TDD区域。通过强度指示信息来配置使用动态TDD的用户设备，可以半静态地划分动态TDD区域，不同的动态TDD区域可以被隔离开。
例如，服务小区的动态TDD区域与邻居小区的动态TDD区域之间具有静态TDD区域。其中，该静态TDD区域内的用户设备采用静态TDD的方式服务，即时隙的上下行配置不会动态地发生改变。
图5是本发明实施例的动态TDD区域和静态TDD区域的一示意图，图6是本发明实施例的动态TDD区域和静态TDD区域的另一示意图。如图5和6所示，一个小区的覆盖范围可以被分成两个区域：静态TDD区域和动态TDD区域。其中，在图6中，静态TDD区域可能被gNB1服务，也可能被gNB2服务。
值得注意的是，本发明实施例所指的动态TDD区域和静态TDD区域并不限于物理意义上的区域，例如还可以是一种虚拟区域(或称为集合)。即，可以将使用动态TDD的一个或多个用户设备所形成区域称为动态TDD区域，将使用静态TDD的一个或多个用户设备所形成的区域称为静态TDD区域。
例如，gNB可以按照距离或者信号强度预先划分一个区域，将该区域内的用户设备都调度为使用动态TDD，而将该区域外的小区内用户设备都调度为使用静态TDD； 但本发明不限于此。
以上仅以静态TDD区域为例，示意性说明了不同的动态TDD区域被隔离开的情况；但本发明不限于此。例如不同的动态TDD区域之间还可以是空白区域，即不进行数据传输的上下行调度。
在本实施例中，网络设备可以向服务小区内一个或多个用户设备发送指示进行动态TDD的时域位置信息，从而可以配置或调度使用动态TDD的用户设备。但本发明不限于此，关于具体如何进行动态TDD的配置或调度，可以参考相关技术。
在本实施例中，对于两个不同的动态TDD区域来说，从这两个区域中任取一个用户设备，这样的两个用户设备间的距离比较大，因此即使这两个区域都采用动态TDD，也不会产生很大的用户设备与用户设备间的干扰。因此，网络设备(例如gNB)可以针对动态TDD区域内的用户设备采用动态TDD，能够动态地分配传输方向(例如上行或下行)。
在本实施例中，网络设备可以配置用户设备进行跨链路干扰的测量；以及接收所述用户设备发送的跨链路干扰的测量结果信息和/或指示是否有跨链路干扰的第一指示信息。
例如，为了设置一个合适的动态TDD区域，gNB可以向用户设备配置跨链路干扰的测量，然后由用户设备上报测量结果。另外，gNB也可以配置用户设备进行测量的时频资源的位置。
如果测量结果满足下述至少一个条件或多个条件的组合，则表明跨链路干扰比较严重：UE间跨链路干扰的强度大于某一个门限值，该门限值例如可以是gNB在配置跨链路干扰测量时发送给用户设备的；信干噪比(SINR，Signal to Interfere plus Noise Ratio)小于某一个门限值，该门限值例如可以是gNB在配置跨链路干扰测量时发送给用户的设备。但本发明不限于此，还可以包括其他的条件。
在本实施例中，网络设备还可以根据所述测量结果信息和/或所述第一指示信息对一个或多个用户设备进行重新配置，以调整所述动态时分双工区域。
例如，gNB可以根据测量结果来进行动态TDD区域的调整。如果测量结果表明跨链路干扰比较严重，gNB可以缩小动态TDD区域的范围；反之，如果测量结果表明跨链路干扰比较小，gNB可以扩大动态TDD区域的范围。
值得注意的是，上述缩小动态TDD区域的范围可以表示减少采用动态TDD的用 户设备的个数；反之，扩大动态TDD区域的范围可以表示增加采用动态TDD的用户设备的个数；但本发明不限于此。
再例如，除了上报测量结果，用户设备还可以上报指示是否有跨链路干扰的第一指示信息，例如是否有严重跨链路干扰的指示消息；然后gNB根据收到的该指示消息来调整动态TDD区域。
在本实施例中，网络设备之间还可以发送指示信息。即，网络设备可以向邻居网络设备发送指示是否有跨链路干扰的第二指示信息，使得所述邻居网络设备调整对应的动态时分双工区域。
例如，gNB1可以发送关于动态TDD区域内跨链路干扰的指示消息，然后收到该指示消息的gNB2会调整对应的动态TDD区域的设置。
表1是两个gNB调整动态TDD区域的例子。
表1
Figure PCTCN2016113609-appb-000001
这里，指示消息可以基于下述至少一个条件或多个条件的组合而产生：gNB的服务用户设备上报的跨链路干扰，且干扰较大；gNB的用户设备上报了存在较大跨链路干扰的指示消息；gNB发现小区的容量或动态TDD区域内的用户设备容量降低，并且降低量超过了某一个门限值。但本发明不限于此，还可以包括其他的条件。
在本实施例中，网络设备可以与邻居网络设备协商进行动态TDD的时域位置。
例如，gNB1可以向邻居gNB2发送信息，该信息中包含该gNB1以动态TDD方式为服务小区服务的时隙(可以称为动态时隙)的位置。和/或，还可以包含该gNB1以静态TDD方式为服务小区服务的时隙(可以称为静态时隙)的位置。
图7是本发明实施例的动态时隙的一示例图，以图7为例，一个时间段可以包含4个时隙，gNB可以在前两个时隙(第一和第二时隙)采用静态TDD(适用于静态TDD区域的UE)，即时隙的DL与UL配置不会动态地发生改变，gNB在最后两个时隙(第三和第四时隙)采用动态TDD(适用于动态TDD区域的UE)。
例如，gNB1将会向邻居gNB2发送一个消息，该消息指示该gNB1将在第三和第四个时隙采用动态TDD的方式服务其小区内的用户设备，通过这个消息，gNB2可以在相同的时隙来采用动态TDD。
在一个实施方式中，网络设备可以向邻居网络设备发送指示进行动态TDD的时域位置的第三指示信息，此外还可以接收所述邻居网络设备发送的确认信息；
例如，gNB1向gNB2发送指示信息指示该gNB1动态时隙的位置，然后gNB2可以设置相同的动态时隙并向gNB1发送确认消息。
在另一个实施方式中，网络设备可以向所述邻居网络设备发送指示进行动态时分双工的时域位置的第三指示信息，并接收所述邻居网络设备发送的建议进行动态时分双工的时域位置的第四指示信息；以及根据第三指示信息和/或第四指示信息确定进行动态时分双工的时域位置；
例如，gNB1向gNB2发送指示信息指示gNB1动态时隙的位置，如果gNB2有着不同的设置，可以发送一个建议的动态时隙的位置给gNB1，gNB1可以发送一个确认消息来接受gNB2建议的动态时隙的位置。
再例如，如果gNB1和gNB2有着不同的动态时隙的配置，且不愿意接受对方的设置，这两个gNB可以选择两者动态时隙位置的交集作为协商后的动态时隙的位置。
在另一个实施方式中，网络设备可以向所述邻居网络设备发送指示进行动态时分双工的时域位置的第三指示信息，并接收所述邻居网络设备发送的拒绝信息。
例如，如果两个gNB无法协商出一个合适的动态时隙的设置，一个gNB(gNB1)可以发送拒绝消息给另一个gNB(gNB2).这种情况下，就无法在任何一个gNB上采用动态TDD的机制。
在本实施例中，网络设备还可以决定处于动态TDD区域的用户设备。例如，gNB需要知道哪些用户设备处在动态TDD区域中，从而可以知道可以应用动态TDD到哪些用户设备。
在本实施例中，网络设备可以配置用户设备进行跨链路干扰的强度的测量和/或 接收信号的强度的测量。用户设备可以在接收信号的强度大于第一阈值和/或跨链路干扰的强度小于第二阈值的情况下，向网络设备发送强度指示信息。网络设备可以将发送了强度指示信息的用户设备确定为处于动态TDD区域的用户设备。
例如，gNB可以配置用户设备测量gNB的发送信号(即UE的接收信号)的强度；如果强度大于某一个门限值(例如可以由gNB配置)，用户设备就发送上报信息(该信息可能是一个指示信息，指示gNB的信号强度大于设定的该门限值，或者是包含测量结果的消息)。这样，gNB就可以认定该用户设备在动态TDD区域内。
再例如，gNB可以配置用户设备测量跨链路干扰的强度，如果干扰强度小于某一个门限值(例如可以由gNB配置)，用户设备就发送上报信息(该信息可能是一个指示信息，指示干扰强度小于设定的该门限值，或者是包含测量结果的消息)。这样，gNB就可以认定该用户设备在动态TDD区域内。
此外，gNB也可以配置用户设备进行测量(例如跨链路干扰测量和/或接收信号测量)的时频资源的位置。gNB可以向用户设备发送这些配置信息，UE在接收到这些配置信息后，可以在配置的时频资源上进行跨链路干扰测量和/或接收信号测量。

步骤801，网络设备与邻居网络设备协商进行动态TDD的时域位置；
步骤802，网络设备配置用户设备进行测量；
步骤803，用户设备进行测量；
例如，用户设备可以进行跨链路干扰的测量，也可以进行接收信号的测量。可以在接收信号的强度大于第一阈值和/或跨链路干扰的强度小于第二阈值的情况下，向网络设备发送强度指示信息。
步骤804，网络设备接收用户设备上报的强度指示信息；
例如，网络设备可以将发送了强度指示信息的用户设备确定为处于动态TDD区域的用户设备；但本发明不限于此，例如也可以从发送了强度指示信息的N个用户设备中再挑选信号强度最强的M个用户设备(M小于N)，等等。
步骤805，网络设备将服务小区内一个或多个用户设备配置为使用动态TDD；
例如，服务小区内被配置为进行动态TDD的用户设备形成动态TDD区域。
步骤806，网络设备接收用户设备上报的跨链路干扰测量结果和/或指示信息；
例如，用户设备可以根据步骤802的配置进行跨链路干扰的测量并上报测量结果；或者，用户设备不上报测量结果，可以仅在跨链路干扰比较严重的情况下上报指示信息，指示存在比较严重的跨链路干扰。
步骤807，网络设备调整动态TDD区域；
例如，网络设备在跨链路干扰比较严重的情况下，可以缩小动态TDD区域；在跨链路干扰不太严重或者较小的情况下，可以维持动态TDD区域或者扩大动态TDD区域。
步骤808，网络设备向邻居网络设备发送指示信息，使得邻居网络设备调整对应的动态TDD区域。
值得注意的是，以上图8仅对本发明实施例进行了示意性说明，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8的记载。
由上述实施例可知，根据强度指示信息配置使用动态TDD的用户设备，可以半静态地划分动态TDD区域，不同的动态TDD区域被隔离开；由此相邻小区进行动态TDD的用户设备之间距离较大，从而可以有效地抑制动态TDD***的跨链路干扰。
