Abstract
一种基于动态时分双工的传输装置、方法以及通信系统。所述传输方法包括:用户设备向多个网络设备发送用于指示所述用户设备在被第一网络设备调度时出现跨链路干扰的上报信息;接收所述多个网络设备中的某一个网络设备发送的调度信息;其中所述调度信息指示所述用户设备的服务网络设备从所述第一网络设备变更为第二网络设备;所述用户设备根据所述调度信息与所述第二网络设备进行数据传输。由此,能够提高用户设备调度的灵活性,并且可以大大提高频谱效率。
Description
本发明实施例涉及通信技术领域,特别涉及一种基于动态时分双工(TDD,Time Division Duplex)的传输装置、方法以及通信系统。
在新无线(NR,New Radio)系统中,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系统中如果采用动态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系统中采用动态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UE2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,网络设备可以采用调整用户设备功率的方式,例如降低用户设备发送上行数据的功率;或者采用延迟调度用户设备的方式,例如将用户设备发送上行数据的时间延迟一个时隙。
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。

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基于动态时分双工的传输方法,应用于用户设备;其中该用户设备基于共信道与多个网络设备连接。
图4是本发明实施例的基于动态TDD的传输方法的一示意图,从用户设备的角度进行说明。如图4所示,所述传输方法包括:

在本实施例中,可以采用共信道多连接(co-channel multiple connectivity)的方式降低跨链路干扰。在共信道多连接的机制下,一个用户设备可以同时与多个工作在相同频率的网络设备(例如TRP)连接,在这种情况下,一个用户设备发送的数据可以被多个网络设备(例如TRP)收到,或者多个网络设备(例如TRP)发送的信息可以被一个用户设备收到。
图5是本发明实施例的共信道多连接的一示例图,如图5所示,UE1可以同时与工作在相同频率(例如f1)的gNB1和gNB2连接。例如,如果UE1在某个时间单元(例如时隙1)被gNB2调度进行上行数据传输,则可以在该时间单元(例如时隙1)称gNB2为UE1的服务网络设备。
图6是本发明实施例的共信道多连接的另一示例图,如图6所示,UE1可以同时与工作在相同频率(例如f2)的gNB1和gNB2连接。例如,如果UE1在某个时间单元(例如时隙2)被gNB1调度进行下行数据接收,则可以在该时间单元(例如时隙2)称gNB1为UE1的服务网络设备。
在本实施例中,某个用户设备在被某个网络设备调度时,可能会出现跨链路干扰;其中,用户设备可以根据网络设备的资源配置信息进行干扰测量,由此可以探测到出现了跨链路干扰。关于具体如何进行跨链路干扰的测量,可以参考现有技术,此处不再赘述。
图7是本发明实施例的用户设备造成跨链路干扰的一示例图,如图7所示,在某个时间单元(例如时隙1),UE1与gNB1进行上行数据传输,UE3和gNB3进行下行数据传输,UE1对UE3造成了跨链路干扰。
图8是本发明实施例的用户设备受到跨链路干扰的一示例图,如图8所示,在某个时间单元(例如时隙2),UE1与gNB1进行下行数据传输,UE2和gNB2进行上行数据传输,UE1受到来自UE2的跨链路干扰。
在本实施例中,用户设备在探测到出现跨链路干扰(对其他用户设备造成了干扰,和/或,受到来自其他用户设备的干扰)的情况下,可以向基于共信道连接的多个网络设备发送上报信息,并基于调度信息变更服务网络设备。
例如,用户设备可以在被第一网络设备调度时该用户设备对其他用户设备造成的跨链路干扰的强度超过第一预设阈值的情况下,向所述多个网络设备发送所述上报信息;
和/或,用户设备可以在被所述第一网络设备调度时所述用户设备受到来自其他用户设备的跨链路干扰的强度超过第二预设阈值的情况下,向所述多个网络设备发送所述上报信息。
值得注意的是,第一预设阈值或第二预设阈值可以由网络设备预先配置,也可以预先被定义或设置,此外第一预设阈值或第二预设阈值的具体数值例如可以根据经验值确定;本发明不限于此。
在本实施例中,所述上报信息可以包括如下的一种或多种信息:
所述用户设备对其他用户设备造成的跨链路干扰的强度信息或强度指示信息,例如信干噪比(SINR,Signal-to-Interference plus Noise Ratio),或者干扰噪声比(INR,Interference Noise Ratio),等等;
值得注意的是,以上仅对上报信息进行了示意性说明,但本发明不限于此,例如还可以包括其他的上报信息。
在本实施例中,基于共信道连接的多个网络设备接收到该上报信息后,其中的一个或多个可以基于预设的条件或者共识确定是否变更该用户设备的服务网络设备,此外还可以确定哪个网络设备为该用户设备服务。可以由某一个网络设备生成调度信息并发送给该用户设备。
在本实施例中,所述调度信息还可以用于指示所述用户设备的传输方向被变更。即,调度信息可以指示:变更服务网络设备,但不变更用户设备的传输方向;或者变更服务网络设备,并且变更用户设备的传输方向。
在本实施例中,所述调度信息可以包括如下的一种或多种信息:
值得注意的是,以上仅对调度信息进行了示意性说明,但本发明不限于此,例如还可以包括其他的调度信息。
在本实施例中,网络设备可以将需要进行传输的调度信息都包含在某个信令中,通过步骤402发送给用户设备。或者,所述一种或多种信息中的部分被所述调度信息所指示,部分通过信令被预先配置。
例如,gNB可以只在调度信息中包含服务gNB的标识信息,其他信息(例如被调度用户设备的传输方向,分配的资源位置等)已经通过其他信令(例如无线资源控制(RRC,Radio Resource Control)信令,介质访问控制(MAC,Media Access Control)层信令,等等)配置给用户设备;当用户设备收到调度信息后,可以自动按照与该服务gNB的标识信息确定对应的其他信息,并根据这些信息进行数据接收和发送。
在本实施例中,所述调度信息还可以包括指示上述一种或多种信息的索引。即,上述调度信息中的内容可以用一个标识(或称为索引)来表示,每个标识对应了一种调度信息的内容;那么gNB可以在调度信息中只发送调度信息标识,这样用户设备就可以根据该标识来确定调度信息的内容。
例如,index 1对应gNB1、上行、功率为10、……;index 2对应gNB2、上行、功率为8、……;index 3对应gNB3、下行、……;……。则网络设备可以仅在调度信息中包含2(表示采用index 2所对应的信息),用户设备可以根据该调度信息将服务网络设备变更为gNB2,并进行功率为8的上行传输。
图9是本发明实施例的基于动态TDD的传输方法的另一示意图,从网络设备和用户设备的角度进行说明。如图9所示,所述传输方法包括:
步骤901,网络设备配置用户设备进行跨链路干扰的测量;
步骤902,用户设备进行跨链路干扰的测量。
步骤903,用户设备向网络设备发送指示出现跨链路干扰的上报信息;
在本实施例中,用户设备可以在被第一网络设备调度时该用户设备对其他用户设备造成的跨链路干扰的强度超过第一预设阈值的情况下,和/或,在被所述第一网络设备调度时所述用户设备受到来自其他用户设备的跨链路干扰的强度超过第二预设阈值的情况下,向多个网络设备发送所述上报信息。
步骤904,网络设备生成调度信息;
在本实施例中,基于共信道连接的多个网络设备接收到该上报信息后,其中的一个或多个可以基于预设的条件或者共识确定是否变更该用户设备的服务网络设备,此外还可以确定哪个网络设备为该用户设备服务。可以由某一个网络设备生成调度信息并发送给该用户设备。
步骤905,用户设备接收所述调度信息;其中所述调度信息指示所述用户设备的服务网络设备从所述第一网络设备变更为第二网络设备;
步骤906,用户设备与网络设备进行数据传输。
例如,可以与变更后的第二网络设备进行基于动态TDD的数据传输;但本发明不限于此,例如也可以不是动态TDD的数据传输。
值得注意的是,以上图9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9的记载。
此外,步骤901中配置测量的网络设备、步骤904中生成调度信息的网络设备、和步骤906中进行调度的网络设备可以不是同一网络设备;当然也可以是同一网络设备。图9为了简单起见,没有进行区分。
以下通过两个实例进行进一步说明。
图10是本发明实施例的基于动态TDD的数据传输的一示例图,示出了变更服务网络设备之前的情况。如图10所示,UE1在某个时间单元(例如时隙1)被调度为向gNB1发送上行数据(可以包括收到向gNB1发送上行数据的调度信息,或者完成了向gNB1发送上行数据);在该时间单元(例如时隙1),UE1与gNB1进行上行数据传输,UE3与gNB3进行下行数据传输,UE1探测到出现了跨链路干扰(UE1对
UE3造成跨链路干扰)。
UE1可以向基于共信道连接的gNB1、gNB2和gNB3发送跨链路干扰的指示信息。gNB1、gNB2和gNB3中的某个网络设备(例如gNB2)可以生成并发送调度信息,将UE1的服务基站由gNB1变为gNB2,但传输方向不发生改变。
图11是本发明实施例的基于动态TDD的数据传输的另一示例图,示出了变更服务网络设备之后的情况。如图11所示,UE1的服务基站被变更为gNB2,在某个时间单元(例如时隙2),UE1与gNB2进行上行数据传输,UE3与gNB3进行下行数据传输。由于gNB2和UE1传输数据时的功率可以较小,能够极大地降低UE1和UE3之间的跨链路干扰。
以上示意性示出了变更服务网络设备但不变更传输方向的例子,以下示出既变更服务网络设备又变更传输方向的例子。
图12是本发明实施例的基于动态TDD的数据传输的一示例图,示出了变更服务网络设备之前的情况。如图12所示,UE1在某个时间单元(例如时隙1)被调度为接收gNB1发送的下行数据(可以包括收到接收gNB1的下行数据的调度信息,或者完成了接收gNB1发送的下行数据);在该时间单元(例如时隙1),UE1与gNB1进行下行数据传输,UE2与gNB2进行上行数据传输,UE1探测到出现了跨链路干扰(UE1受到来自UE2的跨链路干扰)。
UE1可以向基于共信道连接的gNB1、gNB2发送跨链路干扰的指示信息。gNB1、gNB2中的某个网络设备(例如gNB2)可以生成并发送调度信息,将UE1的服务基站由gNB1变为gNB2,且传输方向发生改变(由下行变更为上行)。
图13是本发明实施例的基于动态TDD的数据传输的另一示例图,示出了变更服务网络设备之后的情况。如图13所示,UE1的服务基站被变更为gNB2,在某个时间单元(例如时隙2),UE1与gNB2进行上行数据传输,UE2与gNB2进行上行数据传输,UE1和UE2之间不再产生跨链路干扰。
由上述实施例可知,在基于共信道连接的用户设备被调度时出现跨链路干扰的情况下,服务网络设备从第一网络设备变更为第二网络设备。由此,能够提高用户设备调度的灵活性,可以大大提高频谱效率。
