Description

一种下行控制信息的配置方法及装置 技术领域
本公开涉及通信技术领域，尤其涉及一种下行控制信息的配置方法及装置。
背景技术
相关技术中，终端可以通过自身的载波带宽值来确定DCI(Downlink Control Information，下行控制信息)的长度值。在载波带宽值已知的情况下，DCI的长度值是固定长度值。
在一个DCI中可以包含多个信息所对应的信息域，比如用于指示资源分配的资源分配信息所对应的信息域，用于指示资源分配方式的资源分配指示信息所对应的信息域等等。这些信息域在该DCI中的固定位置上，且长度值为固定的比特长度值。
在新一代通信系统中，一个DCI需要支持的信息是可以配置的，比如以指示传输方向SFI(Slot Format Information，时隙格式信息)的DCI为例，传输方向的变化可能是非常动态的。因此在标准化的讨论中，同意使用GC-PDCCH(Group Common-Physical Downlink Control Channel，分组共用物理下行控制信道)来指示时隙格式。
但是当一个GC-PDCCH用来指示多个带宽部分上的时隙格式的时候，或者当终端支持多个带宽部分的情况下，相关技术中还没有如何配置DCI的方案。

本公开的实施例提供的技术方案可以包括以下有益效果：
本公开实施例中，基站可以为终端配置目标下行控制信息DCI，所述目标DCI包括：至少一个目标带宽部分上的至少一个目标时域传输单元所需要的控制信息。进一步地，终端将承载所述目标DCI的物理下行控制信道PDCCH发送给所述终端，由所述终端从所述PDCCH中解调出目标DCI之后，在被所述目标DCI所指示的目标带宽部分的目标时域传输单元上分别执行对应的控制操作。通过上述过程，可以由基站为终端配置至少一个目标带宽部分上的至少一个目标时域传输单元所需要的控制信息， 提高了5G系统的性能。

本公开实施例提供了一种下行控制信息的配置场景，如图1所示，可以在基站100需要传输公共DCI，或终端200需要进行数据传输时，发送承载目标DCI的PDCCH到终端200。其中，所述目标DCI包括：至少一个目标带宽部分上的至少一个目标时域传输单元所需要的控制信息；所述目标带宽部分是所述目标DCI所指示的带宽部分，所述带宽部分是所述基站与所述终端之间的每个载波上预先指定的频域资源；所述目标时域传输单元是所述目标DCI所指示的所述目标带宽部分上的时域传输单元。
由终端200从所述PDCCH中解调出所述目标DCI之后，被所述目标DCI所指示的目标带宽部分的目标时域传输单元上分别执行对应的控制操作。
下面先从基站侧介绍本公开实施例提供的下行控制信息的配置方法。
本公开实施例提供了一种下行控制信息的配置方法，参照图2所示，图2是根 据一示例性实施例示出的一种下行控制信息的配置方法流程图，可以用于图1所示场景中的基站100，包括以下步骤：
在步骤101中，为终端配置目标下行控制信息DCI；所述目标DCI包括：至少一个目标带宽部分上的至少一个目标时域传输单元所需要的控制信息；
在步骤102中，发送承载所述目标DCI的物理下行控制信道PDCCH到终端，所述目标DCI用于所述终端在被指示的目标带宽部分的目标时域传输单元上分别执行对应的控制操作；其中，所述目标带宽部分是所述目标DCI所指示的带宽部分，所述带宽部分是所述基站与所述终端之间的每个载波上预先指定的频域资源；所述目标时域传输单元是所述目标DCI所指示的所述目标带宽部分上的时域传输单元。
上述实施例中，基站可以为终端配置目标下行控制信息DCI，所述目标DCI包括：至少一个目标带宽部分上的至少一个目标时域传输单元所需要的控制信息。进一步地，终端将承载所述目标DCI的物理下行控制信道PDCCH发送给所述终端，由所述终端从所述PDCCH中解调出目标DCI之后，在被所述目标DCI所指示的目标带宽部分的目标时域传输单元上分别执行对应的控制操作。通过上述过程，可以由基站为终端配置至少一个目标带宽部分上的至少一个目标时域传输单元所需要的控制信息，提高了5G系统的性能。
针对上述步骤101，首先介绍一下带宽部分，如图3所示，带宽部分是基站与所述终端之间的每个载波上预先指定的频域资源，每个终端可以支持至少一个带宽部分。
本公开实施例中，基站为终端配置的目标DCI包括：至少一个目标带宽部分上的至少一个目标时域传输单元所需要的控制信息。其中，所述目标带宽部分是所述目标DCI所指示的所述带宽部分，所述目标时域传输单元则是目标DCI所指示的所述目标带宽部分上的时域传输单元。其中，所述时域传输单元可以是时隙(slot)。
参照4所示，图4是根据图2所示实施例示出的另一种下行控制信息的配置方法流程图，步骤101可以包括以下步骤：
在步骤101-1中，为每个所述目标带宽部分上的每个所述目标时域传输单元分别配置所需要的控制信息，每个目标时域传输单元所需要的控制信息的长度值为预设长度值；
本步骤中，基站可以为每个目标带宽部分上的每个目标时域传输单元分别按 照相关技术，配置所需要的控制信息可选地，每个目标时域传输单元所需要的控制信息的长度值可以为预设长度值，例如5比特。本公开实施例中，每个目标时域传输单元所需要的控制信息可以用于指示数据传输方向、资源分配方式和调制与编码策略中的任一项。
以所述控制信息用于指示数据传输方向为例，则基站可以为2个目标带宽部分，带宽部分1和带宽部分2上的3个时域传输单元n、n+1、n+2分别配置所需要的用于指示数据传输方向的控制信息，例如图5A所示。
在步骤101-2中，将所有所述目标带宽部分上的所有所述目标时域传输单元所需要的所述控制信息，按照预设顺序进行排列，得到目标DCI。
本步骤中，基站可以将上述为每个目标带宽部分上的每个目标时域传输单元所需要的所述控制信息，按照预设顺序进行排列，从而得到目标DCI，所述预设顺序可以是按照带宽部分的编号由小到大，且目标时域传输单元的编号由小到大的顺序，例如图5B所示。
通过上述过程，实现了由基站为终端配置至少一个目标带宽部分上的至少一个目标时域传输单元所需要的所述控制信息的目的，提高了5G系统的性能。
针对上述步骤102，基站可以按照相关技术，通过PDCCH来承载所述目标DCI，进而按照相关技术将所述PDCCH发送给所述终端，所述终端会按照相关技术从所述PDCCH中解调出所述目标DCI，进而在被所述目标DCI所指示的目标带宽部分的目标时域传输单元上分别执行对应的控制操作。
其中，所述控制操作可以包括数据传输操作、资源分配操作和调制编码操作中的任一项。
在本公开实施例中，配置的目标DCI的长度值可以是固定值，例如为预设总长度值；或者所述目标DCI的长度值也可以是可变的，为可配置的总长度值，所述可配置的总长度值可以基于所述目标带宽部分上的所述目标传输单元所需要的控制信息的长度值之和。
如果目标DCI的长度值为所述预设总长度值，则为了避免所有所述目标带宽部分上的所有所述目标时域传输单元所需要的控制信息的长度值之和超过所述预设总长度值，基站在配置所述目标DCI时，可以设置所述目标带宽部分的总数目不超过预设带宽部分数目，所述目标时域传输单元的总数目同样不超过预设时域传输单元数目。
也就是说，可以限定基站在配置长度值为所述预设总长度值的目标DCI时，目标带宽部分的总数目不超过预设带宽部分数目，所述目标时域传输单元的总数目同样不超过预设时域传输单元数目。
例如，预设带宽部分数目可以为2，预设时域传输单元数目为3，则基站在一个目标DCI中最多包括2个目标带宽部分、且每个目标带宽部分最多3个目标时域传输单元所对应的DCI。
在一实施例中，所有所述目标带宽部分上的所有所述目标时域传输单元所需要的控制信息的长度值之和可能小于所述预设总长度值，例如终端支持一个带宽部分，一个DCI只需要传输3个时域传输单元上的传输方向，则所述目标DCI中共有15个比特用来传输不同的时域传输单元所对应的数据传输方向，预设总长度值为30，还有15个比特的字段空闲。
则参照6所示，图6是根据图2所示实施例示出的另一种下行控制信息的配置方法流程图，上述方法还可以包括以下步骤：
在步骤103中，将所述目标DCI中未被目标时域传输单元所需要的控制信息占用的字段设置为保留字段。
本步骤中，基站可以将所述目标DCI中未被目标时域传输单元所需要的控制信息占用的字段设置为保留字段；所述保留字段是不携带任何信息的字段。如果不设置保留字段，则未被目标时域传输单元所需要的控制信息占用的字段会被用来传输其他信息，则在终端侧根据预设总长度值解调出的目标DCI就包括了其他信息，使得解调出的目标DCI不准确。
例如将上述未被所述DCI占用的15比特字段作为保留字段，如图7所示。该保留字段不携带任何信息。
通过上述过程，如果目标DCI的长度值为所述预设总长度值，而所有所述目标带宽部分上的所有所述目标时域传输单元所需要的控制信息的长度值之和小于所述预设总长度值，则可以在所述目标DCI中设置保留字段，该保留字段是未被目标时域传输单元所需要的控制信息占用的且不携带任何信息的字段。通过上述过程，可以在终端按照预设总长度值解调出目标DCI后，确保所获得每个目标带宽部分上的每个所述目标时域传输单元所需要的控制信息的准确性。
在一实施例中，参照8所示，图8是根据图2所示实施例示出的另一种下行控 制信息的配置方法流程图，在执行步骤101之前，上述方法还可以包括以下步骤：
在步骤100中，将所述目标DCI的长度值发送给所述终端，所述目标DCI的长度值用于所述终端从所述PDCCH中解调出所述目标DCI。
其中，如果所述目标DCI的长度值为所述预设总长度值，则所述基站可以通过目标信令将所述预设总长度值发送给所述终端，其中，所述目标信令可以是无线资源控制信令、系统信息、媒体访问控制地址控制单元和物理层信令中的任一个。
所述基站可以通过单独的所述目标信令将所述预设总长度值发送给终端，也可以将所述预设总长度值与某个目标信令中所包括的信息复用该目标信令，从而通过所述目标信令将所述预设总长度值发送给所述终端。
或者，基站还可以将所述预设总长度值通过预定义的方式发送给所述终端，例如在通信协议中预先规定好所述预设总长度值，基站发送触发信令到所述终端，所述终端根据所述触发信令自动获取所述预设总长度值。其中，所述触发信令可以是无线资源控制信令、系统信息、媒体访问控制地址控制单元和物理层信令中的任一个。
如果所述目标DCI的长度值是所述可配置的总长度值，则所述基站可以通过所述目标信令将指示所述可配置的总长度值发送给所述终端。当然，所述目标信令可以是无线资源控制信令、系统信息、媒体访问控制地址控制单元和物理层信令中的任一个。所述基站可以通过单独的所述目标信令将所述实时总长度值发送给终端，也可以将所述实时总长度值与某个目标信令中所包括的信息复用该目标信令，从而通过所述目标信令将所述实时总长度值发送给所述终端。
例如，基站为终端配置的目标带宽部分的数目为1，该目标带宽部分上的目标时域传输单元的数目为3，每个目标时域传输单元所需要的控制信息占5比特。基站将上述信息作为指示可配置的总长度值的信息通过目标信令发送给终端，终端就可以确定目标DCI的长度值为15比特。
上述实施例中，基站还可以在为终端配置目标DCI之前，将所述目标DCI的长度值发送给终端，确保后续终端可以根据所述目标DCI的长度值，在承载目标DCI的PDCCH中成功解调出所述目标DCI。可选地，如果所述目标DCI的长度值为所述预设总长度值，则通过目标信令或预定义的方式将所述预设总长度值发送给所述终端；如果所述目标DCI的长度值为所述可配置的总长度值，则可以通过所述目标信令将指示所述可配置的总长度值的信息发送给所述终端。通过上述过程，可以确保终端解调 出的目标DCI的准确性。
下面从终端侧介绍本公开实施例提供的下行控制信息的配置方法。
参照图9所示，图9是根据一示例性实施例示出的一种下行控制信息的配置方法流程图，可以用于图1所示场景中的终端200，包括以下步骤：
在步骤201中，接收基站发送的承载目标下行控制信息DCI的物理下行控制信道PDCCH；所述目标DCI包括：至少一个目标带宽部分上的目标时域传输单元所需要的控制信息；
在步骤202中，从所述PDCCH中解调出所述目标DCI；
在步骤203中，在被所述目标DCI所指示的目标带宽部分的目标时域传输单元上分别执行对应的控制操作；
其中，所述目标带宽部分是所述目标DCI所指示的带宽部分，所述带宽部分是所述基站与所述终端之间的每个载波上预先指定的频域资源；所述目标时域传输单元是所述目标DCI所指示的所述目标带宽部分上的时域传输单元。
上述实施例中，终端可以接收基站发送的承载目标下行控制信息DCI的物理下行控制信道PDCCH；其中，所述目标DCI包括：至少一个目标带宽部分上的目标时域传输单元所需要的控制信息。进一步地，从所述PDCCH中解调出所述目标DCI，从而在被所述目标DCI所指示的目标带宽部分的目标时域传输单元上分别执行对应的控制操作。上述过程中，终端可以根据基站配置的至少一个目标带宽部分上的至少一个目标时域传输单元所需要的控制信息，在被所述目标DCI所指示的目标带宽部分的目标时域传输单元上分别执行对应的控制操作，提高了5G系统的性能。
针对上述步骤201，基站会在配置完成目标DCI之后，通过PDCCH承载所述目标DCI，进而将所述PDCCH发送给所述终端，所述终端直接接收即可。
其中，所述目标DCI包括：至少一个目标带宽部分上的目标时域传输单元所需要的控制信息；所述目标带宽部分是所述目标DCI所指示的带宽部分，所述带宽部分是所述基站与所述终端之间的每个载波上预先指定的频域资源；所述目标时域传输单元是所述目标DCI所指示的所述目标带宽部分上的时域传输单元。
针对上述步骤202，参照图10所示，图10是根据图9所示实施例示出的另一种下行控制信息的配置方法流程图，步骤202可以包括以下步骤：
在步骤202-1中，接收所述基站发送的所述目标DCI的长度值；
本步骤中，如果所述目标DCI的长度值是预设总长度值，则所述基站可以通过目标信令或预定义的方式将所述目标DCI的长度值发送给所述终端；如果所述目标DCI的长度值是可配置的总长度值，则所述基站可以通过所述目标信令将指示所述可配置的总长度值的信息发送给所述终端，所述终端直接接收后，可以根据指示可配置的总长度值的信息来确定目标DCI的长度值。
其中，所述目标信令可以是无线资源控制信令、系统信息、媒体访问控制地址控制单元和物理层信令中的任一个。
在步骤202-2中，根据所述目标DCI的长度值，从所述物理下行控制信道中解调出所述目标DCI。
本步骤中，终端在确定了目标DCI的长度值之后，就可以按照相关技术，从PDCCH中解调出目标DCI。
针对上述步骤203，参照图11所示，图11是根据图9所示实施例示出的另一种下行控制信息的配置方法流程图，步骤203可以包括以下步骤：
在步骤203-1中，根据每个DCI所对应的预设顺序和预设长度值，从所述目标DCI中获取每个所述目标带宽部分上的每个所述目标时域传输单元所需要的控制信息；
本步骤中，如果预设顺序是按照目标带宽部分的编号由小到大，且目标时域传输单元的编号由小到大的顺序，预设长度值为5比特，则终端可以将所述目标DCI中前5个比特作为目标带宽部分1上的目标时域传输单元1所需要的控制信息，以此类推，可以从所述目标DCI中获取到每个所述目标带宽部分上的每个所述目标时域传输单元所需要的控制信息。
在步骤203-2中，分别在当前所述目标带宽部分上的当前所述目标时域传输单元上执行与当前控制信息对应的控制操作。
本步骤中，如果当前控制信息指示了数据传输方向，则终端在当前目标带宽部分上的当前所述目标时域传输单元执行数据传输操作，当前控制信息指示的是下行，则进行下行数据传输操作；当前控制信息指示的传输方式是上行，则进行上行数据传输操作。
如果当前控制信息指示了资源分配方式，则终端在当前目标带宽部分上的当前 所述目标时域传输单元执行资源分配操作，同样可以根据当前控制信息进行上行资源的分配或下行资源的分配。
如果当前控制信息指示了调制与编码策略，则终端在当前目标带宽部分上的当前所述目标时域传输单元对传输的数据按照所述调制与编码测量进行调制编码操作。
上述实施例中，终端可以根据基站配置的至少一个目标带宽部分上的至少一个目标时域传输单元所需要的控制信息，在被所述目标DCI所指示的目标带宽部分的目标时域传输单元上分别执行对应的控制操作，提高了5G系统的性能。
参照图12所示，图12是根据一示例性实施例示出的一种下行控制信息的配置方法流程图，包括以下步骤：
在步骤301中，基站将目标DCI的长度值发送给终端，所述目标DCI包括：至少一个目标带宽部分上的至少一个目标时域传输单元所需要的控制信息；
其中，所述目标带宽部分是所述目标DCI所指示的带宽部分，所述带宽部分是所述基站与所述终端之间的每个载波上预先指定的频域资源；所述目标时域传输单元是所述目标DCI所指示的所述目标带宽部分上的时域传输单元。
果所述目标DCI的长度值为预设总长度值，则所述基站可以通过目标信令或预定义的方式将所述预设总长度值发送给所述终端。如果所述目标DCI的长度值为可配置的总长度值，则所述基站可以通过目标信令将指示所述可配置的总长度值的信息发送给所述终端。在步骤302中，基站为终端配置目标DCI；
配置的方法如上述实施例所述，在此不再赘述。
可选地，如果所述目标DCI的长度值为所述预设总长度值，所有所述目标带宽部分上的所有所述目标时域传输单元所对应的所述DCI的长度值之和小于所述预设总长度值，则将所述目标DCI中未被控制信息占用的字段设置为保留字段；所述保留字段是不携带任何信息的字段。
在步骤303中，基站发送承载所述目标DCI的物理下行控制信道到终端。
在步骤304中，终端根据所述目标DCI的长度值，从所述物理下行控制信道中解调出所述目标DCI。
在步骤305中，终端根据每个DCI所对应的预设顺序和预设长度值，从所述目标DCI中获取每个所述目标带宽部分上的每个所述目标时域传输单元所需要的控制信息。
在步骤306中，终端分别在当前所述目标带宽部分上的当前所述目标时域传输单元上执行与当前控制信息对应的控制操作。
上述实施例中，由基站为终端配置至少一个目标带宽部分上的至少一个目标时域传输单元所需要的控制信息，终端可以根据基站配置的目标DCI，分别在当前所述目标带宽部分上的当前所述目标时域传输单元上执行与当前控制信息对应的控制操作，提高了5G系统的性能。
