Description

资源指示和接收方法、装置及通信系统 技术领域
本发明实施例涉及通信技术领域，特别涉及一种资源指示和接收方法、装置及通信系统。
背景技术
在长期演进(LTE，Long Term Evolution)系统中，网络设备(例如基站)可以向用户设备(UE，User Equipment)发送下行数据，当物理下行共享信道(PDSCH，Physical Downlink Shared Channel)的数据符号映射到资源块(RB，Resource Block)时，需要避开其他物理信道和/或参考信号所占用的资源粒子(RE，Resource Element)。并且，网络设备需要通过配置信令或者指示信号告知UE这些被占用的RE的位置，使UE能够正确地对数据符号进行解映射，进而正确地进行解码。
在LTE-A(LTE Advanced)系统中，周期性的信道状态信息参考信号(CSI-RS，Channel State Information Reference Signal)由高层信令，例如无线资源控制(RRC，Radio Resource Control)信令配置。网络设备在进行PDSCH映射时，可以根据配置信息获取占用的RE位置及数量，从而进行数据符号的速率匹配。
而非周期性的CSI-RS由RRC信令配置，并且由下行控制信息(DCI，Downlink Control Information)触发，在进行PDSCH速率匹配时可以将分为两种情况：当该非周期性的CSI-RS与PDSCH是发送给同一UE时，该速率匹配将根据该UE的非周期性CSI-RS的配置信息完成；而当该非周期性的CSI-RS与PDSCH不是发送给同一UE时，则可以使用LTE release 11中引入的用于对PDSCH进行RE映射的配置信令。
其中，该配置信令可以给UE配置4个零功率CSI-RS(ZP CSI-RS)，进一步地由DCI指示其中的一个ZP CSI-RS资源，PDSCH速率匹配时将避开这个被其他UE的CSI-RS占用的资源。此时，其他UE也在收到的DCI中被指示出了占用该资源的非周期性CSI测量被触发。
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
发明人发现：现有的资源指示方法中，同一CSI-RS资源出现在针对被调度了下行数据的UE的DCI中以及针对触发了CSI-RS测量的UE的DCI中，即同一CSI-RS资源在这两者的DCI中分别占用了一定的开销。在第五代(5G)通信系统中，由于新无线(NR，New Radio)支持多个非周期性CSI-RS资源出现在同一子帧内，目前的资源指示方法将增加系统整体的下行控制信令开销。

本发明实施例的有益效果在于：网络设备发送用于指示信道状态信息参考信号资源的用户设备组的公共信令；并且发送用于调度下行数据和/或用于指示信道状态信息测量的一个或多个用户设备的专用信令。
由此，能够由通过高层统一配置用于PDSCH速率匹配及CSI测量的资源，可以简化高层配置信息的描述；并且通过公共信令指示UE组的公共信息，能够有效地减少系统整体的控制信令开销；此外通过所述公共信令，能够同时实现用于PDSCH速率匹配的CSI-RS资源的指示和CSI-RS的触发。

实施例1
本发明实施例提供一种资源接收方法，应用于用户设备侧。
图2是本发明实施例的资源接收方法的一示意图，从用户设备侧进行说明。如图2所示，所述方法包括：
步骤201，用户设备接收网络设备发送的用于指示CSI-RS资源的由多个用户设备组成的组的公共信令；其中，所述公共信令被所述组内的用户设备解码；
步骤202，用户设备接收所述网络设备发送的用于调度下行数据和/或用于指示CSI测量的专用信令。
在NR中规定了非周期性CSI-RS资源的发送由DCI触发，在PDSCH速率匹配时也需要由动态信令指示突发出现的非周期性CSI-RS资源。当PDSCH中发送了非周期性CSI-RS资源时，不仅接收数据的UE需要由动态信令指示该非周期性CSI-RS资源占用的RE以便进行PDSCH的速率匹配，接收CSI-RS的UE同样需要由动态信令指示其非周期性CSI-RS资源被触发。
虽然这些动态信令用于不同的目的(PDSCH速率匹配或者CSI-RS触发)，但都是在向UE指示CSI-RS资源被发送。如果在所涉及的各个UE-specific PDCCH中都发送该指示信息，将增加系统整体的控制信令开销。例如，若该指示信息需要M比特而N个UE需要接收该指示信息时，则该指示信息在系统信令中的开销将为M*N比特。
在本实施例中，由UE组公共的控制信令(例如group common PDCCH)承载指 示非周期性CSI-RS资源的指示信息，组内每个UE(即组内所有的UE，但本发明不限于此)都会对公共信令进行解码，从而判断是否有非周期性CSI-RS资源被发送。因此，本发明实施例将发送给不同用户设备的非周期性CSI-RS资源的指示信息合并在一条公共信令中，能够有效地减少系统整体的控制信令开销。
在本实施例中，进行数据接收的用户设备在对所述下行数据进行解映射时，可以避开所述公共信令中指示的所述信道状态信息参考信号资源，以对所述下行数据进行速率匹配。进行CSI测量的用户设备可以根据所述专用信令确定是否触发所述信道状态信息测量；在确定所述信道状态信息测量被触发的情况下，利用所述信道状态信息参考信号资源进行所述信道状态信息测量。
在本实施例中，所述公共信令可以承载在组公共PDCCH(group common PDCCH)中，所述组公共PDCCH中的DCI可以包含一个或多个非周期性CSI-RS的资源信息。所述专用信令可以承载在用户设备专用PDCCH(UE-specific PDCCH)中，所述用户设备专用PDCCH中的DCI可以包括承载所述下行数据的PDSCH的指示信息和/或确认进行非周期CSI测量的确认信息。
例如，组内的某个用户设备可以通过以下两步获取PDSCH映射速率匹配及非周期性CSI-RS触发的相关信息：
第一步，组内所有的UE解码group common PDCCH，确定是否有非周期性CSI-RS资源的传输；若有，则表示该资源上的非周期性CSI-RS被触发。此外，如果某一UE的资源设置(resource setting，如后面所述)中配置了该非周期性CSI-RS资源，UE则认为该非周期性CSI-RS资源可能是发送给自己的。
第二步，UE读取各自的UE-specific PDCCH，当其被调度了下行数据时，解数据映射将避开第一步中指示出CSI-RS资源所占用的RE。另外，同一资源可能被配置给多个用户设备，因此，资源设置中配置了被指示的资源的UE，可以读取UE-specific PDCCH中的1比特确认信息，确定是否是自己需要利用被指示的资源进行CSI测量。
在本实施例中，还可以为每个组配置公共资源池并为每个UE配置资源。
图3是本发明实施例的资源接收方法的另一示意图，从用户设备侧和网络设备侧进行说明。如图3所示，所述方法可以包括：
步骤301，网络设备向用户设备发送用于配置资源的高层信令；其中，所述组内的用户设备被配置有公共的资源池，并且每个用户设备被配置有从所述资源池中选择 的一个或多个资源或资源集。
其中，所述资源池中可以包括一种或多种如下资源：周期性CSI-RS资源，半持续性CSI-RS资源和非周期性CSI-RS资源。
例如，网络设备可以通过高层信令(例如RRC信令)对所服务的UE进行分组，并配置一个公共的CSI-RS资源池给组内UE(可以称为池设置，即pool setting)，资源池中的各CSI-RS资源被配置了不同的参数(例如密度，天线端口数，RE资源样式等)。此外，还可以给各个UE配置CSI测量的参数(可以称为资源设置，即resource setting)，各UE的资源可以是从资源池中选择的。
图4是本发明实施例的配置给UE组的公共资源池的一示意图，如图4所示，在pool setting中，可以根据周期性不同(例如包括周期、半持续、非周期)分别对资源进行编号。
如图4所示，UE 2的resource setting中选择了资源池中的周期性资源1，半持续性资源3和6，以及非周期性资源2，3和7；这些资源可以配置给UE 2用于CSI测量。而对于每个UE来说，由resource setting可以知道resource pool中的哪些资源用于CSI测量，但并不需要知道哪些资源被配置给了其他UE用于CSI测量。
表1示出了图4中各个UE用于CSI测量的资源配置的一个示例。
表1
Figure PCTCN2017096885-appb-000001
对于组内的所有UE，只要资源池中的CSI-RS资源出现在传输该UE下行数据的PDSCH上时，无论该CSI-RS resource是否是发送给该UE的，该UE的数据映射都需要避开这些资源所占用的RE。
如图3所示，所述方法还可以包括：
步骤302，网络设备向用户设备发送用于激活由所述高层信令配置的一个或多个资源或资源集的控制信令。该控制信令例如可以为介质访问控制(MAC，Medium  Access Control)控制元素(Control Element)；但本发明不限于此。
步骤303，网络设备向组内的用户设备发送用于指示CSI-RS资源的公共信令。
在本实施例中，公共信令中的DCI中可以包括：指示所述非周期性CSI-RS资源的比特映射(bitmap)字段；所述bitmap字段中的每一个或每多个比特对应一个非周期性CSI-RS的资源或资源集。
即，为了实现同时指示多个CSI-RS资源，该指示信息可以设计为bitmap的形式，bitmap的各个比特指示某一资源(resource)/资源集(resource set)是否发送。例如，‘0’表示没有发送，‘1’表示发送。此外，根据测量目的的不同，一次测量可能同时触发多个资源，例如波束管理时可能同时触发多个非周期性CSI-RS资源，因此，该bitmap中的1比特可能指示的是一个资源集(resource set)。
例如，假设图4中资源池包含9个非周期CSI-RS资源，而其中资源3和7属于一个资源集，资源4、5和6属于一个资源集，他们始终以资源集的形式被调度。因此，6比特的bitmap中的3，4比特均指示的是资源集的出现与否。
表2示出了包含非周期性CSI-RS指示信息的bitmap的一个示例。

Bitmap 1 2 3 4 5 6
资源池中的非周期性资源编号 1 2 3，7 4，5，6 8 9
然而，group common PDCCH同样需要考虑开销问题，当资源池中配置的非周期性资源的数量较大时，bitmap占用开销将增大，会影响group common PDCCH的覆盖。因此，可以考虑由步骤302中的MAC CE激活资源池中一定数量的资源或资源集，再由group common PDCCH中bitmap来指示触发的资源或资源集。该bitmap的位数与被激活的资源或资源集数目相同。
例如，group common PDCCH中由6比特的bitmap指示非周期性资源，当资源池中的非周期性资源或资源集大于6个时，由MAC CE信令激活其中的6个，再由group common PDCCH中的bitmap来指示其触发情况；当非周期性资源或资源集小于或等于6个时，则可以跳过步骤302中MAC CE的激活，直接由bitmap来指示。
步骤304，网络设备向一个或多个用户设备分别发送用于调度下行数据和/或用于 指示信道状态信息测量的专用信令。
值得注意的是，以上图3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3的记载。
由上述实施例可知，网络设备发送用于指示信道状态信息参考信号资源的用户设备组的公共信令；并且发送用于调度下行数据和/或用于指示信道状态信息测量的一个或多个用户设备的专用信令。
由此，能够由通过高层统一配置用于PDSCH速率匹配及CSI测量的资源，可以简化高层配置信息的描述。并且通过公共信令指示组的公共信息，能够有效地减少系统整体的控制信令开销；例如在PDSCH承载了多个CSI-RS资源和PDSCH在多用户多输入多输出(MU-MIMO)的发送方式下，该指示信息需要通知多个UE时。此外通过所述公共信令，能够同时实现用于PDSCH速率匹配的CSI-RS资源的指示和CSI-RS的触发。
