Description

信息传输装置、方法以及通信系统 技术领域
本发明涉及无线通信技术领域，特别涉及一种信息传输装置、方法以及通信系统。
背景技术
在对第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)中长期演进(LTE，Long Term Evolution)的时分双工(TDD，Time Division Duplex)系统的研究中，增强的干扰管理和业务自适应(eIMTA，enhanced Interference Mitigation and Traffic Adaption)作为一种自适应技术用于打破固定的TDD帧结构配置，灵活地改变上下行配比。
然而，改变一个小区的TDD帧结构配置会对相邻小区产生影响，例如两个相邻的小区采用相反的上下行配置，这将使得系统中不再单纯地存在基站对用户设备的干扰以及用户设备对基站的干扰，而是出现了基站对基站的干扰以及用户设备对用户设备的干扰。
通常，由于基站架设的比较高，基站和基站之间多为直传路径，衰减较小，在一定程度上增加了基站和基站之间的干扰。在eIMTA的研究中为了减少干扰，对各个小区的上下行重新配置进行了诸多限制；例如，宏基站的TDD帧结构是不做重新配置的，或者仅允许上行被重配为下行，或者仅在个别子帧上允许上下行重配等。
然而，在未来第五代(5G)移动通信系统中，通信场景会更加多样化，网络架构也越来越灵活，同时上下行业务配比的需求也越来越灵活多变。在这种情况下，eIMTA中设置的诸多限制将不能满足未来业务需求。
因而，5G将需要更加灵活的双工方式：即在兼顾系统干扰的情况下，每个小区都可以根据自己用户的业务状况来选择上下行配置。以异构网络为例，在宏基站(例如称为MTP)的覆盖范围下，多个传输点(TP，Transmission Point)可以同时支持上行和下行传输业务。例如宏基站(MTP)进行下行通信；而其覆盖范围内的小基站(例如称为STP)既可以进行下行通信，也可以进行上行通信，与该STP的覆盖范围内用户的业务需求有关。
反过来，MTP也可以进行上行通信；而该MTP覆盖范围内的STP既可以进行下 行通信，也可以进行上行通信；这种灵活传输方式可以实现灵活的上下行业务传输。
此外，与多点传输不同，灵活的上下行调度中不仅距离较近的基站可以联合进行传输，距离较远的多个基站(甚至彼此无X2接口连接的多个基站)也可能被调度为同时进行灵活的上下行传输。因此，干扰(例如基站和基站间的干扰)抑制方案需要进一步增强。
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。

在本申请中，移动站或设备可以被称为“用户设备”(UE，User Equipment)。UE可以是固定的或移动的，并且也可以称为移动台、终端、接入终端、用户单元、站等。UE可以是蜂窝电话、个人数字助理(PDA)、无线调制解调器、无线通信设备、手持设备、膝上型计算机、无绳电话等。
实施例1
本发明实施例提供一种信息传输方法，应用于用户设备。图1是本发明实施例的信息传输方法的一示意图，从用户设备侧进行说明。如图1所示，该信息传输方法包括：
步骤101，用户设备接收第一基站发送的对应该第一基站和第二基站之间信道的第一信道信息；
步骤102，用户设备将该第一信道信息所对应的第一基站的标识信息和/或该第一信道信息上报给该第二基站。
在本实施例中，以异构网络为例进行说明。其中，第二基站可以为宏基站(或宏传输点，本文可称为MTP)，该宏基站产生的宏小区(例如Macro cell)可以为用户设备提供服务；第一基站可以为小基站(本文可称为STP)，该小基站产生的小小区(例如Small cell)可以为用户设备提供服务。第一基站和第二基站之间可以通过X2接口进行信息交互，也可以不具有X2接口而通过定义新的空口格式进行信息交互。
值得注意的是，本发明不限于此，可以根据实际的需要确定具体的场景。以下仅以异构网络中，MTP进行下行传输而STP进行上行传输为例进行说明；此外还可以适用于其他的网络结构或场景，例如还适用于MTP进行上行传输而STP进行下行传输的场景。
在异构网络中MTP进行下行传输而STP进行上行传输的场景下，MTP作为发送端会对作为接收端的STP产生干扰。通常，接收端是可以通过信道估计得到发送端与接收端之间的信道信息的。然而，在当前的LTE系统中，下行采用的是正交频分复用(OFDM，Orthogonal Frequency Division Multiplexing)传输，而上行采用的是单载波频分复用(SC-FDMA，Simple-Carrier Frequency Division Multiplexing)传输，即作为接收端的STP不能估计到MTP和STP之间的信道信息。
在本实施例中，为获得MTP和STP之间的信道信息，STP可以在空闲时隙接收MTP发送的参考信号，并估计出MTP和STP之间的信道状态信息(CSI，Channel State Information)；即通过信道估计获得第一基站和第二基站之间的CSI。
此外，也可进行相应的无线资源测量而获得第一基站和第二基站之间的信道测量信息；例如参考信号接收功率(RSRP，Reference Signal Received Power)，和/或参考信号接收质量(RSRQ，Reference Signal Received Quality)，等等。
由此，即使第一基站和第二基站之间没有X2连接，通过用户设备的转发，第二基站也可以获得第一基站和第二基站之间信道的第一信道信息，该第一信道信息可以是表征短期或瞬时的参数(例如CSI)，也可以是表征长期的参数(例如RSRP和/或RSRQ)。
在步骤101中，用户设备可以接收一个或多个第一基站发送的第一信道信息。该第一信道信息可以由第一基站通过主信息块(MIB，Master Information Block)和/或系统信息块(SIB，System Information Block)发送，或者通过下行控制信息(DCI，Downlink Control Information)发送。
图2是本发明实施例的第一基站向用户设备发送第一信道信息的一示意图，如图2所示，该异构网络中例如包括两个第一基站STP1和STP2；STP1可以向其覆盖范围内的用户设备UE1和UE2广播STP1和MTP之间的第一信道信息，STP2可以向其覆盖范围内的用户设备UE2和UE3广播STP2和MTP之间的第一信道信息。
在步骤102中，用户设备可以将一个或多个第一信道信息所对应的第一基站的标识信息上报给该第二基站；此外还可以将一个或多个第一信道信息上报给第二基站。
图3是本发明实施例的用户设备向第二基站上报信息的一示意图，如图3所示，UE1可以向MTP上报STP1和MTP之间的第一信道信息和/或STP1的标识信息；UE2可以向MTP上报STP2和MTP之间的第一信道信息和/或STP2的标识信息。
此外，图3没有示出UE3上报的情况。用户设备可以根据需要进行反馈，例如具体哪些用户设备需要上报第一信道信息和/或STP标识信息，可以由第二基站发送高层信令进行配置。
由此，通过用户设备的转发，MTP可以获得灵活双工传输所必要的第一信道信息，此外MTP还可以获得用户设备和MTP之间信道的第二信道信息；MTP可以根据这些信道信息进行合理的调度决策，因而可以支持STP和用户设备同时进行灵活 的上下行传输。
图4是本发明实施例的信息传输方法的另一示意图，从用户设备侧进行进一步说明。如图4所示，该信息传输方法包括：
步骤401，用户设备接收第一基站发送的对应该第一基站和第二基站之间信道的第一信道信息；
步骤402，用户设备获得该用户设备与该第二基站之间信道的第二信道信息；
在本实施例中，该第二信道信息可以是表征短期或瞬时的参数(例如通过信道估计而获得的CSI)，也可以是表征长期的参数(例如通过无线资源测量而获得的RSRP和/或RSRQ)。
步骤403，用户设备确定需要向第二基站上报的反馈信息；
在本实施例中，用户设备可以将第一信道信息所对应的第一基站的标识信息和/或该第一信道信息上报给该第二基站；此外也可以将该第二信道信息上报给该第二基站。
关于反馈信息的具体内容，可以根据实际的场景确定，例如可以如后所述地根据方向信息确定；但本发明不限于此。
步骤404，用户设备在某一个或多个上行时隙向第二基站上报该反馈信息。
在本实施例中，第一信道信息所对应的第一基站的标识信息和/或该第一信道信息可以在某一时隙反馈给第二基站，而第二信道信息可以在另一时隙反馈给第二基站；或者，也可以在一个时隙中发送上述反馈信息。本发明不限于此，可以根据实际需要确定反馈的时机和方式。
步骤405，用户设备接收第二基站发送的调度信息，并根据该调度信息进行上下行传输。
在本实施例中，例如第二基站可以同时调度该第一基站和该用户设备。由此，用户设备可以和第一基站同时进行灵活的上下行传输，避免或者缓解多个设备之间进行上下行传输的干扰。
以上从用户设备侧进行了说明，以下从多个设备(第一基站、用户设备和第二基站)的角度进行说明。
图5是本发明实施例的信息传输方法的另一示意图，示出了用户设备、第一基站和第二基站之间交互的情况。如图5所示，该信息传输方法包括：
步骤501，第一基站获得第一基站和第二基站之间的第一信道信息；
在本实施例中，可以通过信道估计而获得第一基站和第二基站之间的CSI，和/或通过无线资源测量而获得第一基站和第二基站之间的RSRP和/或RSRQ等。例如，STP可以在空闲时隙接收MTP发送的参考信号，并估计出STP和MTP之间的CSI。
为了简单起见，以下仅以第一信道信息是CSI为例进行说明，其中CSI包含方向信息；例如如下信息的其中一种或多种：波束编号(BI，Beam Index)，预编码矩阵指示(PMI，Precoding Matrix Indicator)，信道状态信息参考信号资源指示(CRI，CSI-RS resource indicator)。但本发明不限于此，对于其他第一信道信息可以类似地进行处理。
步骤502，第一基站向用户设备发送第一信道信息；
在本实施例中，例如STP可以广播/发送STP和MTP之间信道的CSI和STP的编号给该STP覆盖范围内的用户设备。例如，STP可以通过MIB或者SIB广播，或者通过DCI发送。
步骤503，用户设备获得该用户设备与该第二基站之间信道的第二信道信息；
在本实施例中，例如用户设备可以通过信道估计而获得该用户设备与该第二基站之间信道的CSI，和/或通过无线资源测量而获得该用户设备与该第二基站之间信道的RSRP和/或RSRQ，等等。
步骤504，用户设备将反馈信息上报给该第二基站。
在本实施例中，用户设备可以上报该第一信道信息所对应的第一基站的标识信息和/或该第一信道信息；此外还可以上报该第二信道信息。例如，具有下行通信需求的用户设备将收到的STP的信息连同自己的待反馈信息，在上行时隙转发给MTP。
在本实施例中，用户设备可以通过周期性反馈方式向第二基站上报信息，也可以通过非周期性反馈方式向第二基站上报信息。此外，可以同时上报上述反馈信息，也可以在不同的时刻分别上报上述反馈信息。
在一个实施方式中，上报信息中的第一基站的标识信息可以包括：与第二信道信息的方向相同(例如BI/PMI/CRI相同，即不适合同时进行上下行传输)的第一信道信息所对应的第一基站的标识信息。
例如，每个用户设备向MTP反馈自已的BI/PMI/CRI，并且反馈具有相同BI/PMI/CRI的STP的编号。以图3和BI为例，如果UE 1自己的BI(即UE1与MTP之间信道的BI)为4，STP 1向UE 1发送的BI(即STP 1与MTP之间信道的BI) 也为4，则UE1将该STP 1的标识信息发送给MTP。这样MTP就可以避免将该用户设备和该STP调度到一起进行灵活的上下行传输，由此可以避免或者缓解干扰。
在另一个实施方式中，上报信息中的第一基站的标识信息可以包括：与该用户设备适合同时进行上下行传输的一个或多个第一基站的标识信息。
例如，每个用户设备向MTP反馈自己的BI/PMI/CRI，并且反馈适合与该用户设备一起进行灵活的上下行传输的STP的编号，此外还可以反馈该STP的BI/PMI/CRI。这里适合与该用户设备进行灵活的上下行传输的STP可以是一个或多个。
在另一个实施方式中，上报信息中的第一基站的标识信息可以包括：用户设备接收到的全部第一信道信息所对应的第一基站的标识信息。
例如，每个用户设备向MTP反馈自己BI/PMI/CRI，并且反馈接收到的所有STP的编号，此外还可以反馈所有的STP发送的BI/PMI/CRI；这种实施方式可能将涉及到较大的反馈量。
值得注意的是，这里STP的编号既可以是在整个网络中STP的唯一编号，也可以是在例如宏基站覆盖范围内的为所有STP临时设置的编号；本发明不限于此。此外，以上实施方式仅以BI/PMI/CRI为例进行了说明，对于其他的信道信息可以相应地进行处理。
步骤505，第二基站根据上报的反馈信息进行调度决策。
在本实施例中，第二基站可以基于第二信道信息以及第一信道信息所对应的第一基站的标识信息进行调度决策，或者也可以基于第二信道信息、第一信道信息以及该第一信道信息所对应的第一基站的标识信息进行调度决策。
步骤506，第二基站向第一基站和/或用户设备发送调度信息；
在本实施例中，例如第二基站可以同时调度该第一基站和该用户设备，使得该第一基站和该用户设备同时进行上下行传输。
在本实施例中，一个或多个用户设备可以同时和一个或多个第一基站进行上下行传输(例如一个用户设备处于下行传输，而多个第一基站处于上行传输)，不同的用户设备对应的第一基站可以是不同的；可以根据实际需求确定具体的场景。
值得注意的是，图5仅示意性地对本发明实施例进行了说明，但本发明不限于此。可以适当地调整各个步骤之间的执行顺序，例如步骤503可以在步骤501之前执行，也可以与步骤501并行执行。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，例如步骤504可以在不同的时刻执行，分别发送第一信道信息和第二信道信息。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的记载。
由上述实施例可知，第一基站获得该第一基站和第二基站之间的信道信息并发送给用户设备，用户设备将该信道信息转发给第二基站；由此，进行调度决策的第二基站可以获得灵活双工传输所必要的信道信息，因而可以支持多个设备同时进行灵活的上下行传输，避免或者缓解多个设备之间进行上下行传输的干扰。
实施例2
本发明实施例提供一种信息传输方法，应用于第一基站中，与实施例1相同的内容不再赘述。
图6是本发明实施例的信息传输方法的一示意图，如图6所示，该信息传输方法包括：
步骤601，第一基站获得该第一基站与该第二基站之间信道的第一信道信息；
步骤602，第一基站向用户设备发送该第一基站和该第二基站之间信道的第一信道信息。
在本实施例中，第一信道信息可以包括：通过信道估计而获得的CSI。例如，为获得MTP和STP之间的信道信息，STP可以在空闲时隙接收MTP发送的参考信号，并估计出MTP和STP之间的CSI；即通过信道估计获得第一基站和第二基站之间的CSI。
或者，第一信道信息也可以包括：通过无线资源测量而获得的信道测量信息。例如，第一基站可以进行相应的无线资源测量，从而获得第一基站和第二基站之间的RSRP和/或RSRQ，等等。
由此，第一基站可以获得第一基站和第二基站之间信道的第一信道信息，该第一信道信息可以是表征短期或瞬时的参数(例如CSI)，也可以是表征长期的参数(例如RSRP和/或RSRQ)。并且，第一基站可以将该第一信道信息发送给用户设备。
如图6所示，该信息传输方法还可以包括：
步骤603，第一基站接收第二基站发送的调度信息；
在本实施例中，例如第二基站可以同时调度该第一基站和该用户设备，使得该第一基站和该用户设备同时进行上下行传输。
在本实施例中，一个或多个用户设备可以同时和一个或多个第一基站进行上下行传输(例如一个用户设备处于下行传输，而多个第一基站处于上行传输)，不同的用户设备对应的第一基站可以是不同的；可以根据实际需求确定具体的场景。
在本实施例中，该调度信息可以使用不同于现有DCI格式1至5的新的DCI格式来发送。例如，可以将该新的DCI格式定义为DCI格式6(DCI format 6)。
例如，在MTP进行下行传输而STP进行上行传输时，DCI format 6用于相关的上下行传输调度，可以包含以下信息：
Figure PCTCN2016074129-appb-000001
与STP进行上行传输的用户设备所使用的物理上行控制信道(PUCCH，Physical Uplink Control Channel)和/或物理上行共享信道(PUSCH，Physical Uplink Shared Channel)资源；和/或
Figure PCTCN2016074129-appb-000002
进行上行传输的用户设备的PUSCH和PUCCH的发送功率控制命令。
或者除了以上信息外，同时还包含DCI format 2D中的信息。MTP可以通过DCI format 6发送调度信息，STP和相应的用户设备可以接收通过DCI format 6承载的调度信息，由此进行灵活的上下行传输。
由上述实施例可知，第一基站获得该第一基站和第二基站之间的信道信息并发送给用户设备，用户设备将该信道信息转发给第二基站；由此，进行调度决策的第二基站可以获得灵活双工传输所必要的信道信息，因而可以支持多个设备同时进行灵活的上下行传输，避免或者缓解多个设备之间进行上下行传输的干扰。
实施例3

图7是本发明实施例的信息传输方法的一示意图，如图7所示，该信息传输方法包括：

步骤702，第二基站接收用户设备上报的该用户设备和该第二基站之间信道的第二信道信息。
其中，第一信道信息和/或第二信道信息可以包括：通过信道估计而获得的CSI， 和/或通过无线资源测量而获得的信道测量信息；但本发明不限于此，例如还可以是其他的信道信息。
在本实施例中，步骤701和步骤702可以同时进行，例如可以同时接收到用户设备发送的第一信道信息和第二信道信息。此外，步骤701和步骤702也可以不同时进行，例如可以在不同的时刻分别接收到用户设备发送的第一信道信息和第二信道信息。步骤701和步骤702之间的执行顺序不限于此，例如步骤702还可以在步骤701之前执行。
如图7所示，该信息传输方法还可以包括：
步骤703，第二基站基于用户设备上报的反馈信息进行调度决策；
在本实施例中，第二基站可以基于一个或多个用户设备上报的反馈信息进行调度决策。此外，第二基站在进行调度决策时，还可以参考一个或多个用户设备发送的第一信道信息。
步骤704，第二基站向第一基站和用户设备发送调度信息；
在本实施例中，例如第二基站可以同时调度该第一基站和该用户设备，使得第一基站和用户设备同时进行上下行传输。
其中，调度信息可以使用不同于现有DCI格式1至5的新的DCI格式来发送。例如，可以将该新的DCI格式定义为DCI格式6(DCI format 6)，可以参考实施例2中的相关内容。
由上述实施例可知，第一基站获得该第一基站和第二基站之间的信道信息并发送给用户设备，用户设备将该信道信息转发给第二基站；由此，进行调度决策的第二基站可以获得灵活双工传输所必要的信道信息，因而可以支持多个设备同时进行灵活的上下行传输，避免或者缓解多个设备之间进行上下行传输的干扰。

在本实施例中，第一信道信息和/或第二信道信息可以包括：通过信道估计而获得的CSI，和/或通过无线资源测量而获得的信道测量信息。但本发明不限于此，还可以是其他的信道信息。

本发明实施例还提供一种用户设备，配置有上述的信息传输装置800。
图9是本发明实施例的用户设备的一示意图。如图9所示，该用户设备900可以包括中央处理器100和存储器140；存储器140耦合到中央处理器100。值得注意的 是，该图是示例性的；还可以使用其他类型的结构，来补充或代替该结构，以实现电信功能或其他功能。
在一个实施方式中，信息传输装置800的功能可以被集成到中央处理器100中。其中，中央处理器100可以被配置为实现实施例1中所述的信息传输方法。
例如，中央处理器100可以被配置为进行如下的控制：接收第一基站发送的对应所述第一基站和第二基站之间信道的第一信道信息；将所述第一信道信息所对应的第一基站的标识信息和/或所述第一信道信息上报给所述第二基站。
在另一个实施方式中，信息传输装置800可以与中央处理器100分开配置，例如可以将信息传输装置800配置为与中央处理器100连接的芯片，通过中央处理器100的控制来实现信息传输装置800的功能。
如图9所示，该用户设备900还可以包括：通信模块110、输入单元120、显示器160、电源170。其中，上述部件的功能与现有技术类似，此处不再赘述。值得注意的是，用户设备900也并不是必须要包括图9中所示的所有部件，上述部件并不是必需的；此外，用户设备900还可以包括图9中没有示出的部件，可以参考现有技术。
在本实施例中，用户设备可以被配置为使用不同于现有传输模式1至10的新的传输模式(TM，Transmission Mode)；例如该新的传输模式可以被定义为TM 11。
例如，如果用户设备被高层配置为通过小区无线网络临时标识(C-RNTI，Cell Radio Network Temporary Identifier)加扰的循环冗余校验(CRC，Cyclic Redundancy Check)来为物理下行控制信道(PDCCH，Physical Downlink Control Channel)译码，则用户设备按照下表1来为PDCCH和相应的物理下行共享信道(PDSCH，Physical Downlink Shared Channel)译码。

Figure PCTCN2016074129-appb-000004
现有标准中例如TM 9和TM 10，均是最多可以支持8个数据流的多输入多输出(MIMO，Multiple Input Multiple Output)传输，但TM 10中使用DCI format 2D，而TM 9使用DCI format 2C，即TM 10中支持发送端多个天线不在同一个基站上。
如上表1和2所示，TM 11也可以与TM 9类似，最多支持8个数据流的MIMO传输。然而相比TM 10，TM 11中同时发送数据的发送天线甚至可以不全是在基站处，也可以是在用户设备处(进行上行传输的UE)。
所以TM 11可以配置给与MTP进行下行传输的用户设备，同时进行上行传输的STP也可以接收到相应的TM配置，并进而搜索DCI format 6，获得利用STP进行上行传输的用户设备的调度信息。同时与MTP进行下行传输的用户设备也可以通过搜索DCI format 6而获得下行调度信息，尤其是天线端口信息。
值得注意的是，表1和表2仅示意性示出了TM 11的内容，但本发明不限于此。此外，关于传输模式(例如TM 1至10)的内容可以参考相关的标准，此处不再详细说明。
由上述实施例可知，第一基站获得该第一基站和第二基站之间的信道信息并发送给用户设备，用户设备将该信道信息转发给第二基站；由此，进行调度决策的第二基站可以获得灵活双工传输所必要的信道信息，因而可以支持多个设备同时进行灵活的上下行传输，避免或者缓解多个设备之间进行上下行传输的干扰。
