  • the embodiments of the present invention relate to the field of communications technologies, and in particular, to a transmission apparatus, method, and communication system for suppressing interference information.
  • Dynamic Time Division Duplex supports dynamically allocating uplink and downlink configurations of data transmissions to a basic unit (for example, a slot).
  • the transmission direction between each network device (eg, gNB) and the user equipment may be dynamically changed with one time unit (eg, one time slot) as a basic unit.

Description

抑制干扰信息的传输装置、方法以及通信系统 技术领域
本发明实施例涉及通信技术领域，特别涉及一种抑制干扰信息的传输装置、方法以及通信系统。
背景技术
在新无线(NR，New Radio)系统中，动态时分双工(TDD，Time Division Duplex)支持以一个时间单元(例如一个时隙(slot))为基本单元动态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，网络设备之间需要相互协调。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：在采用动态TDD时配置信息是动态传输的，例如某一时隙 的上下行传输方向在该时隙内的第一个或前几个符号(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网络设备间的回路(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。

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抑制干扰信息的传输方法，应用于进行动态TDD的用户设备。图4是本发明实施例的抑制干扰信息的传输方法的一示意图，如图4所示，所述传输方法包括：
步骤402，用户设备向服务网络设备或者一个或多个邻居网络设备发送用于抑制动态TDD跨链路干扰的上报信息；
其中，所述上报信息可以包括如下的一种或多种：
服务小区在特定时间范围内的传输方向信息，
一个或多个邻居小区在特定时间范围内的传输方向信息，
用于指示所述用户设备在发送所述上报信息之前是否测量到来自一个或多个邻居小区的跨链路干扰的指示信息，
用于指示所述用户设备在发送所述上报信息之前是否对一个或多个邻居小区的用户设备产生跨链路干扰的指示信息，
来自一个或多个邻居小区的跨链路干扰的测量结果信息，
所述用户设备在发送所述上报信息之前受到跨链路干扰或者对其他用户设备造成跨链路干扰的资源位置信息，
所述用户设备在发送所述上报信息之后可能受到跨链路干扰或者会对其他用户设备造成跨链路干扰的资源位置信息。
值得注意的是，以上仅示意性示出了上报信息(即用于抑制跨链路干扰的信息)的一些具体信息，但本发明不限于此，例如还可以包括其他的可以用于抑制跨链路干扰的信息。
在本实施例中，所述特定时间范围可以是用于数据传输的时间段，例如可以包括如下的任一种：一个或多个时隙(slot)、一个或多个子帧(subframe)、一个或多个帧(frame)、一个或多个符号(symbol)。但本发明不限于此，还可以是使用其他时间单元表示的一段时间。
在本实施例中，用户设备发送所述上报信息的时频资源可以由所述服务网络设备或者所述邻居网络设备配置。此外，用户设备还可以基于通知信息(详细内容如后所述)中的发送功率信息和/或时间信息发送所述上报信息。
例如，每个gNB可以配置与邻居gNB相正交的时频资源来让各自小区内的服务用户设备发送上报信息(也可称为上报信令)。进一步，每个gNB还可以与邻居gNB交互这个时频资源配置的信息，并可以与邻居gNB协商这个时频资源的配置。
用户设备可以根据服务gNB发送的通知信息(也可称为通知信令)中指示的发送功率来发送上报信令。但本发明不限于此，例如这个发送功率的大小也可以由服务gNB通过其他信令通知用户设备，例如无线资源控制(RRC，Radio Resource Control)信令，介质访问控制(MAC，Media Access Control)层的控制信令等。
此外，用户设备还可以根据服务gNB发送的通知信令中指示的时间信息(例如时间提前信息，timing advance information)来发送该上报信令。但本发明不限于此，例如这个时间信息也可以由其他信令发送，如RRC信令，MAC层的控制信令等。
在本实施例中，可以对发送上报信息的用户设备进行配置，即可以限制哪些用户设备可以发送该上报信息。
例如，发送上报信息的用户设备可以满足如下一个或多个条件：
所述用户设备被所述服务网络设备配置为需要发送所述上报信息；
所述用户设备被所述服务网络设备调度为在发送了所述上报信息后进行数据的发送或者接收；
所述用户设备接收到所述邻居网络设备发送的所述通知信息；
所述用户设备发现所述服务网络设备的传输方向与所述邻居网络设备的传输方向不同；
所述用户设备在发送所述上报信息之前测量到来自一个或多个邻居小区的跨链路干扰，或者探测到会对一个或多个邻居小区的用户设备造成跨链路干扰；
所述用户设备预测在发送所述上报信息之后将受到一个或多个邻居小区的跨链路干扰或者将对一个或多个邻居小区的用户设备产生跨链路干扰。
值得注意的是，以上仅示意性示出了一些具体的条件，但本发明不限于此，例如还可以包括其他的条件。
以上对于本发明的上报信息进行了说明。由此通过用户设备向服务网络设备或者邻居网络设备上报抑制干扰信息，可以将这些信息及时地通知给邻居网络设备。
在本实施例中，在用户设备发送上报信息之前，还可以接收到网络设备发送的通知信息。
如图4所示，所述传输方法还可以包括：
步骤401，用户设备接收所述服务网络设备或者所述邻居网络设备的通知信息；
其中，所述通知信息可以包括如下的一种或多种：服务小区在特定时间范围内的传输方向信息、一个或多个邻居小区在特定时间范围内的传输方向信息、发送所述上报信息的发送功率信息、发送所述上报信息的时间信息、发送所述上报信息的用户设备信息；但本发明不限于此。
在本实施例中，所述特定时间范围可以是用于数据传输的时间段，例如可以包括如下的任一种：一个或多个时隙(slot)、一个或多个子帧(subframe)、一个或多个帧(frame)、一个或多个符号(symbol)。但本发明不限于此，还可以是使用其他时间单元表示的一段时间。
在本实施例中，用户设备接收所述通知信息的时频资源可以由所述服务网络设备或者所述邻居网络设备配置。此外，用户设备还可以基于该通知信息中的发送功率信息和/或时间信息发送所述上报信息。
例如，每个gNB可以配置与邻居gNB相正交的时频资源来发送该通知信息(也可称为通知信令)。进一步，每个gNB可以与邻居gNB交互这个时频资源配置的信息，并可以与邻居gNB协商这个时频资源的配置。
在本实施例中，所述通知信息可以由所述服务网络设备或者所述邻居网络设备使 用大于其他信号功率的功率发送。
图5是本发明实施例的网络设备发送通知信息的一示意图，如图5所示，与网络设备发送其他信号(例如下行控制信号、下行数据等)所采用的功率P1(形成如图5所示的信号接收区域A1)比较，网络设备可以以更大的功率P2(形成如图5所示的信号接收区域A2)发送该通知信息。此外，网络设备还可以将该发送功率P2的大小或者P2和P1的差值ΔP配置给用户设备。
由此，可以使更多的用户设备(包括本小区的用户设备和邻居小区的用户设备)接收到该通知信息，使得更多的用户设备能够根据该通知信息向服务网络设备或者邻居网络设备发送上报信息，从而提高信息传输的可靠性。
值得注意的是，图4仅示意性地对本发明进行了说明，但本发明不限于此。例如步骤401中发送通知信息的网络设备和步骤402中接收上报信息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。
例如，可以是该用户设备的服务网络设备发送该通知信息，而该用户设备的邻居网络设备接收该上报信息；或者，该用户设备的邻居网络设备发送该通知信息，而该用户设备的服务网络设备接收该上报信息；或者，该用户设备的服务网络设备发送该通知信息，该用户设备的服务网络设备和邻居网络设备都接收该上报信息；或者，该用户设备的邻居网络设备发送该通知信息，该用户设备的服务网络设备和邻居网络设备都接收该上报信息。图4为了简单起见，没有进行区分。
以下以两个实例对本发明实施例进行进一步说明。
图6是本发明实施例的信息传输方法的一示例图，如图6所示，gNB1是UE1的服务网络设备，gNB2是UE1的邻居网络设备。gNB1在时刻t1发送通知信息，例如指示gNB1(或者对应的小区)在一段时间内的上下行传输方向；UE1在t1接收到该通知信息，在时刻t2处UE1可以向gNB2发送上报信息，例如该上报信息指示gNB1(或者对应的小区)在一段时间内的上下行传输方向。
由此，通过邻小区(对应gNB1)的用户设备UE1，gNB2可以及时地获得抑制跨链路干扰的信息(例如来自gNB1)。
图7是本发明实施例的信息传输方法的另一示例图，如图7所示，gNB1是UE1的服务网络设备，gNB2是UE1的邻居网络设备。gNB2在时刻t1发送通知信息，例如指示gNB2(或者对应的小区)在一段时间内的上下行传输方向；UE1在t1接收到 该通知信息，在时刻t2处UE1可以向gNB1发送上报信息，例如该上报信息指示gNB2(或者对应的小区)在一段时间内的上下行传输方向。
由此，通过本小区(对应gNB1)的用户设备UE1，gNB1可以及时地获得抑制跨链路干扰的信息(例如来自gNB2)。
以上对于上报信息和通知信息进行了示意性说明。以下对于承载上报信息和通知信息的时间单元结构进行说明。其中，以下以该时间单元是时隙为例进行说明，但本发明不限于此，例如该时间单元还可以是子帧或帧，或者其他的时间单元。
在一个实施方式中，所述上报信息和所述通知信息可以被承载在包含下行数据的时间单元结构中，所述时间单元结构中在时域上依次承载有所述通知信息、所述上报信息以及所述下行数据。
图8是本发明实施例的时间单元结构的一示意图，如图8所示，该时间单元结构中可以承载通知信令(notification signalling)801、其他下行控制信令802、间隔(gap)803、上报信令(reporting signalling)804、其他上行控制信令805、数据区域806(包括下行数据+可选的下行控制信令)、空白区域807。
或者，所述上报信息和所述通知信息可以被承载在包含上行数据的时间单元结构中，所述时间单元结构中在时域上依次承载有所述通知信息、所述上报信息以及所述上行数据。
图9是本发明实施例的时间单元结构的另一示意图，如图9所示，该时间单元结构中可以承载通知信令(notification signalling)901、其他下行控制信令902、间隔(gap)903、上报信令(reporting signalling)904、其他上行控制信令905、数据区域906(包括上行数据+可选的下行控制信令)、空白区域907。
在本实施方式中，可以将图8和图9所示的时间单元结构称为格式1，在该格式1中，在时域上依次承载有所述通知信息、所述上报信息以及数据(上行数据或下行数据)。
其中，通知信令801或901可以如上所述；例如指示的传输方向是本时间单元(例如时隙)内数据的传输方向或本时间单元(例如时隙)之后的一个或多个时间单元(例如时隙)的数据传输方向。
上报信令804或904也可以如上所述，例如上报的传输方向是本时间单元(例如时隙)内本小区(即用户设备的服务小区)或相邻小区的传输方向，或者是本时间单 元(例如时隙)之后的一个或多个时间单元(例如时隙)内本小区或相邻小区的数据传输方向。
此外，其他下行控制信令802或902可以是类似于物理下行控制信道(PDCCH，Physical Downlink Control Channel)的下行控制信令(例如资源分配，前面时隙的上行数据的ACK/NACK等)。
对于其他上行控制信令805或905，例如可以包括前面时隙的下行数据的ACK/NACK、信道质量指示(CQI，Channel Quality Indicator)、跨链路干扰的测量结果，等等；可以包括其中的一种或多种。此外，如果没有上行控制信令需要发送，传输该其他上行控制信令的资源可以用来发送数据。
再例如，用户设备上报上述跨链路干扰的测量结果需要满足下述至少一个条件或几个条件的组合：用户设备发现其服务小区的传输方向与邻居小区不同；用户设备在发送上述其他上行控制信令前测量到其受到了跨链路干扰或者探测到其会造成跨链路干扰；用户设备预测在其发送上述上行控制信令后在发送数据时会造成对邻居小区用户设备的跨链路干扰，或在接收数据时会受到邻居小区用户设备造成的跨链路干扰；用户设备被服务gNB调度了数据的发送或接收。但本发明不限于此，例如还可以包括其他的条件。
对于数据区域806，可以包括下行数据；可选地，还可以包括下行控制信令。用户设备可以根据前述的下行控制信令802来接收下行数据。如果gNB根据用户设备的上报和自己的测量发现了跨链路干扰，可以通过在数据区域806发送下行控制信令来调整用户设备传输数据的调度。
对于数据区域906，可以包括上行数据；可选地，还可以包括下行控制信令。用户设备可以根据前述的下行控制信令802来发送上行数据。如果gNB根据用户设备的上报和自己的测量发现了跨链路干扰，可以通过在数据区域906发送下行控制信令来调整用户设备传输数据的调度。
而在空白区域807或907，gNB或UE不发送任何信息，旨在减少对邻居小区的干扰。但本发明不限于此，例如也可能没有该空白区域。
值得注意的是，上述发送各信息的时频资源的位置只是示例，实际系统中，可以根据gNB的配置来发送。
图10是本发明实施例的采用格式1的多个时间单元的一示意图，以两个时间单 元是两个时隙为例。如图10所示，时隙1中的通知信令可以指示该时隙1的服务小区的传输方向，时隙1中的上报信令可以上报该时隙1的服务小区的传输方向或者该时隙1的邻居小区的传输方向，时隙1中的下行数据的传输结果(ACK/NACK)可以在时隙2中的上行控制信令中指示。
在另一个实施方式中，所述上报信息和所述通知信息可以被承载在包含下行数据的时间单元结构中，所述时间单元结构中在时域上依次承载有所述通知信息、所述下行数据以及所述上报信息。
图11是本发明实施例的时间单元结构的一示意图，如图11所示，该时间单元结构中可以承载通知信令(notification signalling)1101、其他下行控制信令1102、数据区域1103(包括下行数据)、间隔(gap)1104、上报信令(reporting signalling)1105、其他上行控制信令1106、空白区域1107。
或者，所述上报信息和所述通知信息可以被承载在包含上行数据的时间单元结构中，所述时间单元结构中在时域上依次承载有所述通知信息、所述上行数以及据所述上报信息。
图12是本发明实施例的时间单元结构的另一示意图，如图12所示，该时间单元结构中可以承载通知信令(notification signalling)1201、其他下行控制信令1202、数据区域1203(包括上行数据)、间隔(gap)1204、上报信令(reporting signalling)1205、空白区域1206。
在本实施方式中，可以将图11和图12所示的时间单元结构称为格式2，在该格式2中，在时域上依次承载有所述通知信息、数据(上行数据或下行数据)以及所述上报信息。
其中，通知信令1101或1201可以如上所述；例如指示的传输方向是本时间单元(例如时隙)之后的一个或多个时间单元(例如时隙)的数据传输方向。
上报信令1105或1205也可以如上所述，例如上报的传输方向是本时间单元(例如时隙)之后的一个或多个时间单元(例如时隙)内本小区(即用户设备的服务小区)或相邻小区的数据传输方向。
此外，其他下行控制信令1102或1202可以是类似于物理下行控制信道(PDCCH，Physical Downlink Control Channel)的下行控制信令(例如资源分配，前面时隙的上行数据的ACK/NACK，等等)。
对于其他上行控制信令1106，例如可以包括前面时隙的下行数据的ACK/NACK、信道质量指示(CQI，Channel Quality Indicator)、跨链路干扰的测量结果，等等；可以包括其中的一种或多种。
在例如，用户设备上报上述跨链路干扰的测量结果需要满足下述至少一个条件或几个条件的组合：用户设备发现其服务小区在本时间单元(例如时隙)后的一个或多个时间单元(例如时隙)的传输方向与邻居小区不同；用户设备在发送上述其他上行控制信令前测量到其受到了跨链路干扰或者探测到其会造成跨链路干扰；用户设备预测在其发送上述上行控制信令后在发送数据时会造成对邻居小区用户设备的跨链路干扰，或在接收数据时会受到邻居小区用户设备造成的跨链路干扰；用户设备在本时间单元(例如时隙)后的一个或多个时间单元(例如时隙)被服务gNB调度了数据的发送或接收。但本发明不限于此，例如还可以包括其他的条件。
而在空白区域1107或1206，gNB或UE不发送任何信息，旨在减少对邻居小区的干扰。但本发明不限于此，例如也可能没有该空白区域。
值得注意的是，上述发送各信息的时频资源的位置只是示例，实际系统中，可以根据gNB的配置来发送。
图13是本发明实施例的采用格式2的多个时间单元的一示意图，以两个时间单元是两个时隙为例。如图13所示，时隙1中的通知信令可以指示时隙2的服务小区的传输方向，时隙1中的上报信令可以上报时隙2的服务小区的传输方向或者时隙2的邻居小区的传输方向。
值得注意的是，上述格式1或格式2可以在gNB采用了动态TDD来服务其小区内的用户设备时才采用，通知信令和上报信令可以在gNB采用了动态TDD来服务其小区内的用户设备后才发送；但本发明不限于此。
由上述实施例可知，通过用户设备向服务网络设备或者邻居网络设备上报抑制干扰信息，可以将这些信息及时地通知给邻居网络设备，从而有效地抑制动态TDD系统的跨链路干扰。
