图2示出了从网络设备描述的根据本发明一实施例的传输调度信息的方法100的示意性流程图，该方法100在包括至少两级用于下行控制的专用信道的通信系统中执行，各级专用信道所对应的时频资源不同，其中，该专用信道在仅被所分配至的终端设备检测，如图2所示，该方法100包括：
S110，网络设备为目标终端设备分配第一级专用信道和第二级专用信道；
S120，该网络设备通过预设的第一时频资源发送该第一级专用信道的指示信息；
S130，该网络设备通过该第一级专用信道，向该目标终端设备发送该第二级专用信道的指示信息；或
该网络设备通过该第一级专用信道，向该目标终端设备发送第三时频资源的指示信息，并通过该第三时频资源，向该目标终端设备发送该第二级专用信道的指示信息，其中，该第三时频资源属于下行数据信道PDSCH的时频资源；
S140，该网络设备通过该第二级专用信道，向该目标终端设备发送针对该目标终端设备的专用调度信息。
在本发明实施例中，使用至少两级用于下行控制的专用信道传输终端设备的专用调度信息。
这里，“专用信道”是指仅被所分配至终端设备检测的信道，不失一般性，例如，如果专用信道#1被网络设备分配给终端设备#A(即，目标终端设备的一例)，则网络设备可以向终端设备#A下发该专用信道#1所对应的时频资源(也可以称为，“搜索空间”)的指示信息，从而终端设备#A能够在该专用信道#1所对应的时频资源进行检测(或者说，搜索)，以获取网络设备下发的信息，例如，该针对终端设备#A的专用调度信息。并且，系统内的除 终端设备#A以外的终端设备不会在专用信道#1所对应的时频资源上进行检测。
另外，“专用调度信息”是指网络设备需要对一个终端设备进行资源调度时下发给该用户设备的用于该资源调度的信息，作为示例而非限定，上述“针对终端设备#A的专用调度信息”可以包括现有技术中需要通过在EPDCCH或PDCCH的专用搜索区域传输给终端设备#A的信息，例如，针对终端设备#A的下行调度的分配信息，或者，针对终端设备#A的上行调度的授权信息等。
并且，在本发明实施例中，通过至少两级专用信道下发专用调度信息。
其中，第二级专用信道用于下发专用调度信息，第一级专用信道用于下发用于指示第二级专用信道的时频资源(或者说，搜索空间)的指示信息。
不失一般性，对于针对终端设备#A的专用调度信息，承载于分配给终端设备#A的第二级专用信道(以下，为了便于理解和说明，记做专用信道#2)。
网络设备可以通过分配给终端设备#A的第一级专用信道(例如，上述专用信道#1)下发用于指示专用信道#2的时频资源的指示信息。
例如，网络设备可以通过上述专用信道#1直接下发专用信道#2的时频资源的指示信息(以下，为了便于理解和区别，记做指示信息#1)。
或者，网络设备也可以上述专用信道#1，通过例如下行控制信息(DCI，Downlink Control Information)消息下发PDSCH中的某一时频资源的指示信息(以下，为了便于理解和区别，记做指示信息#2)，并通过该指示信息#2所指示的PDSCH中的时频资源，下发指示信息#1。
从而终端设备#A可以通过专用信道#1直接或间接获取指示信息#1，并根据该指示信息#1，确定专用信道#2(具体地说，是专用信道#2的时频资源)，并在专用信道#2的时频资源上，获取针对终端设备#A的专用调度信息。
并且，网络设备可以根据预设的用于传输系统信息(例如，MIB)的时频资源(即，第一时频资源的一例)向终端设备#A下发EPDCCH#1的时频资源的指示信息，从而终端设备#A可以通过上述预设的时频资源，获取专用信道#1的时频资源的指示信息，从而确定专用信道#1的时频资源，并在专用信道#1的时频资源上，通过专用信道#1获取上述专用信道#2的时频资源的指示信息。
由此可见，在传输针对终端设备#A的专用调度信息的过程中，仅在传输专用信道#1的时频资源的指示信息时，占用了用于传输系统信息的时频资源，能够提高传输调度信息的灵活性，改善系统性能和用户体验。
可选地，该专用信道为专用的EPDCCH。
具体地说，在本发明实施例中，通信系统中的EPDCCH可以分为专用的EPDCCH和公用的EPDCCH(随后对该公用的EPDCCH进行详细说明)，其中，“专用的EPDCCH”是指仅被所分配至终端设备检测的EPDCCH，例如，如果专用的EPDCCH#1(以下，为了便于理解和说明，简称EPDCCH#1)被网络设备分配给终端设备#A，则网络设备可以向终端设备#A下发该EPDCCH#1所对应的时频资源(也可以称为，“搜索空间”)的指示信息，从而终端设备#A能够在该EPDCCH#1所对应的时频资源进行检测(或者说，搜索)，以获取网络设备下发的信息，例如，该针对终端设备#A的专用调度信息。并且，系统内的除终端设备#A以外的终端设备不会在EPDCCH#1所对应的时频资源上进行检测。
应理解，以上列举的以EPDCCH作为专用信道的方案仅为示例性说明，本发明并未限定于此，例如，还可以使用下一代增强的下行控制信道(英文全称可以为：Future Enhanced Physical Downlink Control Channel，英文简称可以为：FEPDCCH)或专用的PDCCH作为专用信道。
为了便于理解和说明，以下，以EPDCCH作为专用信道为例，对上述方法100的具体过程进行详细说明。
不失一般性，以向终端设备#A(即，目标终端设备的一例)下发控制信息的过程为例，对上述方法100进行详细说明。
网络设备可以从系统提供的时频资源中，确定第一级EPDCCH(即，第一级专用信道的一例)的时频资源(以下，为了便于理解和区分，记做，时频资源A)。
可选地，网络设备为目标终端设备分配第一级专用EPDCCH包括：
网络设备根据需要调度的终端设备的数量确定第一级专用EPDCCH的时频资源的大小。
具体地说，在本发明实施例中，上述至少两级EPDCCH中的第一级EPDCCH可以是被视为分配给当前需要调度的所用终端设备的EPDCCH，或者说，该第一级EPDCCH的时频资源被作为承载当前需要调度的所有终 端设备的搜索空间。
此情况下，网络设备可以根据当前需要调度的终端设备的数量，确定时频资源A的大小，例如，如果当前需要调度的终端设备的数量较大，则需要分配给各终端设备的第二级EPDCCH的数量也较大，相应地，第二级EPDCCH的时频资源的指示信息(或者，用于承载第二级EPDCCH的时频资源的指示信息的PDSCH中的时频资源)的数量也较多，因此，可以分配较多的时频资源(例如，符号、子载波或资源块)作为上述时频资源A。
通过根据当前需要调度的终端设备的数量，分配第一级EPDCCH的时频资源，能够避免在需要调度的终端设备较少时，仍占有较多的时频资源进行资源调度，能够避免对系统资源的浪费。
如上所述可知，上述EPDCCH#1的时频资源(以下，为了便于理解和区分，记做，时频资源A1)可以视为时频资源A的一部分。
作为实例而非限定，网络设备可以根据当前需要调度的各终端设备(以下，为了便于理解和区分，记做，终端设备#A～终端设备#N)的数量N、指示分配给各终端设备的第二级EPDCCH的时频资源的指示信息(即，指示信息#1)的长度或大小，或PDSCH中用于承载该指示信息#1的时频资源的指示信息(即，指示信息#2)的长度或大小，将时频资源A分为X个子时频资源(以下，为了便于理解和区分，记做，子时频资源#A1～子时频资源#AX)，其中，X≥N，并且终端设备#A～终端设备#N与子时频资源#A1～子时频资源#AN之间的一一对应，即，每个子时频资源被分配给所对应的终端设备。
此情况下，由于分配给多个终端设备的指示信息#1或指示信息#2均承载于时频资源A，需要使各终端设备能够区分出哪个指示信息是需要获取的。
对此，例如，网络设备在通过专用EPDCCH#1向终端设备#A下发指示信息#1或指示信息#2时，可以将终端设备#A的相关信息承载于该终端设备#A所对应的子时频资源(即，上述时频资源A1)上。从而，终端设备#A在获知时频资源A的位置后，可以在时频资源A上进行检测，将携带该终端设备#A的相关信息的子时频资源作为时频资源A1，并在该时频资源A1上接收网络设备发送给该终端设备#A的指示信息#1(即，EPDCCH#2的时频资源的指示信息)或指示信息#2(即，PDSCH中用于承载指示信息#1的时频资源的指示信息)。
再例如，该指示信息#1或指示信息#2可以包括资源指示部分(承载时频资源的指示信息的部分)和设备相关信息部分(承载终端设备的相关信息的部分)。从而，终端设备#A在获知时频资源A的位置后，可以在时频资源A上进行检测，将携带该终端设备#A的相关信息的指示信息，视为网络设备发送给该终端设备#A的指示信息#1或指示信息#2。
再例如，网络设备可以获取预设的映射规则，该映射规则可以指示终端设备#A～终端设备#N的相关信息与子时频资源#A1～子时频资源#AN之间的一一对应关系。并且，终端设备可以获取相同或相对应的映射规则，从而，例如，对于终端设备#A，网络设备和该终端设备#A能够从时频资源A确定相同的子时频资源，作为时频资源A1，并在该时频资源A1上接收网络设备发送给该终端设备#A的指示信息#1或指示信息#2。
作为实例而非限定，终端设备的相关信息可以包括终端设备的设备标识，应理解，以上列举的终端设备#A的相关信息仅为实例性说明，本发明并未限定于此，其他能够唯一地指示一个用户设备的信息均落入本发明的保护范围内，只要确保网络设备和各终端设备所使用的信息相同或相对应即可，例如，终端设备的相关信息还可以包括终端设备的媒体接入控制(英文全称可以为：Media Access Control，英文简称可以为：MAC)地址或网际协议(英文全称可以为：Internet Protocol，英文简称可以为：IP)地址等。
应理解，以上列举的分配第一级EPDCCH的方法，或者说，确定第一级EPDCCH的时频资源的方法仅为示例性说明，本发明并未限定于此，也可以根据网络设备的能力，确定该网络设备能够在一个调度周期内调度的终端设备的最大数量，并根据该最大数量和各第二级EPDCCH的指示信息(即，上述指示信息#1或指示信息#2)的大小或长度，在每次分配时，分配固定数量的时频资源给第一级EPDCCH，只要使第一级EPDCCH的时频资源能够满足各第二级EPDCCH的指示信息(即，上述指示信息#1或指示信息#2)的传输需求即可。
可选地，该用户设备在同一时刻仅检测所述第一级EPDCCH和所述第二级EPDCCH中的一方。
具体地说，在本发明实施例中，在终端设备#A在通过上述时频资源A1获知网络设备分配给该终端设备#A的第二级EPDCCH的时频资源(以下，为了便于理解和区分，记做，时频资源B)之前，无法对第二级EPDCCH 进行检测或搜索，而仅检测第一级EPDCCH。
当终端设备#A在通过上述时频资源A1获知时频资源B之后，该终端设备#A可以仅在该时频资源B进行搜索或检测，而停止在时频资源A1上进行的针对第一级EPDCCH的搜索和检测。
相对应地，网络设备可以将该时频资源A1释放并重新分配给其他终端设备。
下面，对第一级EPDCCH(即，第一级专用信道的一例)的时频资源的配置方式进行详细说明。
可选地，该第一级专用信道的时频资源属于至少两个资源块RB
具体地说，第一级EPDCCH(即，第一级专用信道的一例)的时频资源的分配可以以资源块(英文全称可以为：Resource Block，英文简称可以为：RB)为单位，即，第一级EPDCCH的时频资源可以属于至少两个RB，需要说明的是，“属于至少两个RB”是指，该第一级EPDCCH的时频资源可以包括至少两个RB的全部时频资源，也可以包括该至少两个RB的部分时频资源，例如，包括每个RB的一半数量的子载波或符号。
可选地，该第一级专用信道的时频资源所属于的至少两个RB非连续。
具体地说，图4示出了第一级EPDCCH的时频资源的分布方式的另一例的示意图，如图4所示，第一级EPDCCH的时频资源可以承载于不相邻的至少两个RB中。从而，能够提高传输的分集增益。
可选地，该第一级专用信道的时频资源在频域上位于预先设定的带宽的两端。
具体地说，图3示出了第一级EPDCCH的时频资源的分布方式的一例。如图3所示，第一级EPDCCH的时频资源可以属于预先设定的带宽两端的至少两个RB。
并且，在本发明实施例中，该预先设定的带宽是指网络设备和终端设备预先约定的带宽，作为示例而非限定，该预先设定的带宽可以是通信系统所使用的系统带宽。
可选地，该第一级专用信道的时频资源所属于的至少两个RB连续，其中，属于第一RB的该第一级专用信道的时频资源与属于第二RB的该第一级专用信道的时频资源非连续。
具体地说，第一级EPDCCH的时频资源可以属于至少两个RB，并且， 该至少两个RB中，只有部分(例如，一半数量)的子载波被用于作为第一级EPDCCH的时频资源。并且，当第一级EPDCCH的时频资源可以所属于两个RB相邻时，这两个RB中被用于作为第一级EPDCCH的时频资源的子载波不连续。
可选地，该第一级专用信道的时频资源包括同一传输时间间隔TTI的前K个符号，K≥1。
具体地说，图5示出了第一级EPDCCH的时频资源的分布方式的另一例的示意图，如图5所示，第一级EPDCCH的时频资源可以为所属于的RB的前K个符号，并且该RB的剩余符号可以作为例如，PDSCH的时频资源。
应理解，以上列举的一个RB内除作为第一级EPDCCH的时频资源以外的符号的作用仅为示例性说明，本发明并未特别限定。
并且，上述K的具体数值可以根据需要任意确定，作为示例而非限定，例如，当一个RB包括7个符号时，第一级EPDCCH的时频资源可以为所属于的RB的第1个符号，或，前4个符号。
可选地，该网络设备为该目标终端设备分配第一级专用信道和第二级专用信道，包括：
根据该目标终端设备所访问的业务的时延要求，为述目标终端设备分配第一级专用信道。
具体地说，例如，当终端设备所访问的业务对时延要求较高时，终端设备无需检测一个RB的所有符号，便能够通过第一级专用EPDCCH的时频资源，获得第二级专用EPDCCH的时频资源的指示信息，从而能够加快针对该终端设备的调度速度，减少终端设备的业务访问时延。
可选地，该第一级专用信道的时频资源属于同一TTI中的M个资源块RB，M≥1。
具体地说，第一级EPDCCH的时频资源可以为一个TTI所属于的RB的M个RB，并且该TTI中剩余的RB可以作为例如，PDSCH的时频资源。
并且，上述M的具体数值可以根据需要任意确定，本发明并未特别限定。
可选地，该第一级专用信道包括第一TTI内的至少一个信道单元CE。
具体地说，在本发明实施例中，该第一级专用信道(具体地说，是该第一级专用信道的时频资源)可以以信道单元(CE，Channel Element)为单位 进行划分，即，该第一级专用信道可以包括一个TTI(即，第一TTI的一例)中的至少一个CE。
可选地，该第一级专用信道的时频资源在该第一TTI内集中式配置或分布式配置，其中，
分布式配置是指：当该第一TTI内的被分配给该第一级专用信道的RB仅用于承载该第一级专用信道时，每个该CE的时频资源属于该第一TTI内的至少两个RB，或
当该第一TTI内的被分配给该第一级专用信道的RB用于承载该第一级专用信道和其他信道时，每个该CE所包括的资源单元RE在频域上非连续；
集中式配置是指：当该第一TTI内的被分配给该第一级专用信道的RB仅用于承载该第一级专用信道时，每个该CE的时频资源属于该第一TTI内的同一RB，或
当该第一TTI内的被分配给该第一级专用信道的RB用于承载该第一级专用信道和其他信道时，每个该CE所包括的资源单元RE在频域上连续。
具体地说，在本发明实施例中，第一级专用信道可以集中式配置在同一TTI中，或者，第一级专用信道也可以分布式配置在同一TTI中。
首先，对分布式配置的情况进行详细说明。
在本发明实施例中，该第一级专用信道可以与其他信道采用频分复用方式复用同一TTI内的各RB，即，在一个TTI内的被分配给第一专用信道的RB仅用于承载第一级专用信道，而不能用于承载其他信道(例如，PDSCH)。
此情况下，例如，网络设备可以将时频资源A分为子时频资源#A1～子时频资源#AX，每个子时频子时频资源用于承载一个终端设备的第一级专用信道，如果上述各子时频资源包括同一TTI内的一个或多个CE，并且，每个CE可以属于至少两个RB，则可以认为第一级专用信道分布式配置在该TTI中。
如图7所示，网络设备分配给一个终端设备的CE(例如，CE#1，可以用于承载第一级专用信道)可以属于至少两个RB，进一步，该CE可以包括至少两个RB的部分时频资源，例如，包括每个RB的部分符号，并且，同一RB的剩余符号可以分配给其他终端设备的CE而作为分配给其他终端设备的第一级专用信道。
或者，网络设备分配给一个终端设备的CE(例如，CE#1，可以用于承 载第一级专用信道)可以属于至少两个RB，并且该CE可以包括至少两个RB的部分时频资源，例如，包括每个RB的部分子载波。
需要说明的是，图7中所示的CE#1～CE#4可以分别被分配给多个终端设备而分别作为多个终端设备的第一级专用信道。
或者，图7中所示的CE#1～CE#4中的部分或全部CE也可以被分配给多同一终端设备而分别作为一个终端设备的第一级专用信道。
在第一级专用信道与其他信道采用频分复用方式复用同一TTI时，通过使第一级专用信道包括一个或多个CE，并使每个CE的时频资源属于至少两个RB中，能够使第一级专用信道分布式(或者说，分散地)配置在系统带宽中，从而能够有效增加分集增益，进一步提高本发明的可靠性和实用性。
在本发明实施例中，该第一级专用信道可以与其他信道采用时分复用方式复用同一TTI内的各RB，例如，如图5所示，在一个TTI内的被分配给第一专用信道的RB中的部分符号用于承载第一级专用信道，同一RB中的其他符号可以其他信道(例如，PDSCH)。
此情况下，如果第一级专用信道包括同一TTI内的一个或多个CE，并且，每个CE所包括的资源单元(RE，Resource Element)不连续，则可以认为第一级专用信道分布式配置在该TTI中。
如图8所示，网络设备分配给一个终端设备的CE(例如，CE#1)可以属于同一TTI中的部分(例如，2个RB)，进一步，该CE可以包括2个RB的部分符号(例如，第一个符号)，同一RB的剩余符号可以分配给其他信道(例如，PDSCH)。
在第一级专用信道与其他信道采用时分复用方式复用同一TTI时，通过使第一级专用信道包括一个或多个CE，并使每个CE所包括的RE非连续，能够使第一级专用信道分布式(或者说，分散地)配置在系统带宽中，从而能够有效增加分集增益，进一步提高本发明的可靠性和实用性。
下面，对集中式配置的情况进行详细说明。
在本发明实施例中，该第一级专用信道可以与其他信道采用频分复用方式复用同一TTI内的各RB，即，在一个TTI内的被分配给第一专用信道的RB仅用于承载第一级专用信道，而不能用于承载其他信道(例如，PDSCH)。
此情况下，例如，网络设备可以将时频资源A分为子时频资源#A1～子时频资源#AX，每个子时频子时频资源用于承载一个终端设备的第一级专用 信道，如果上述各子时频资源包括同一TTI内的一个或多个CE，并且，并且，每个CE的时频资源可以属于同一RB，则可以认为第一级专用信道集中式配置在该TTI中。
如图9所示，网络设备分配给一个终端设备的CE(用于承载该终端设备的第一级专用信道)可以属于同一RB。并且，该分配给一个终端设备的CE可以仅占用一个RB中的部分符号或部分子载波，其他的符号或子载波可以被分配给其他终端设备，而作为其他终端设备的第一级专用信道的时频资源。
需要说明的是，图9中所示的CE#1～CE#4可以分别被分配给多个终端设备而分别作为多个终端设备的第一级专用信道。
在第一级专用信道与其他信道采用频分复用方式复用同一TTI时，通过使第一级专用信道包括一个或多个CE，并使每个CE的时频资源属于同一RB中，能够使第一级专用信道集中式(或者说，集中地)配置在系统带宽中，从而能够根据信道的干扰情况，选择信道质量较好的信道集中配置第一级专用信道，进一步提高本发明的可靠性和实用性。
在本发明实施例中，该第一级专用信道可以与其他信道采用时分复用方式复用同一TTI内的各RB，例如，如图5所示，在一个TTI内的被分配给第一专用信道的RB中的部分符号用于承载第一级专用信道，同一RB中的其他符号可以其他信道(例如，PDSCH)。
此情况下，如果第一级专用信道包括同一TTI内的一个或多个CE，并且，每个CE所包括的资源单元(RE，Resource Element)连续，则可以认为第一级专用信道集中式配置在该TTI中。
如图10所示，网络设备分配给一个终端设备的CE(例如，CE#1)可以属于同一TTI中的全部RB，进一步，该CE可以包括同一TTI中的全部RB的部分符号(例如，第一个符号)，同一RB的剩余符号可以分配给其他信道(例如，PDSCH)。
在第一级专用信道与其他信道采用时分复用方式复用同一TTI时，通过使第一级专用信道包括一个或多个CE，并使每个CE所包括的RE连续，能够使第一级专用信道集中式(或者说，集中地)配置在系统带宽中，从而能够根据信道的干扰情况，选择信道质量较好的信道集中配置第一级专用信道，进一步提高本发明的可靠性和实用性。
应理解，以上列举的时频资源的分布方式仅为示例性说明，本发明并未限定于此，也可以根据需求进行调整。
另外，如图3至图10所示，第一级专用信道中还可以包括用于承载参考信道(或者说，导频信号)的时频资源。
并且，在本发明实施例中，每个端口可以独立的占用一个时频资源，例如，图3至图7中所示的端口，例如，端口#1～端口#4，或端口#A～端口#D中的任意端口，可以为一个端口。
或者，在本发明实施例中，多个端口可以复用同一时频资源，例如，图8至图10中所示的端口，例如，端口#E可以包括多个(例如，4个)端口，或者，图10中端口#F可以包括多个(例如，4个)端口，并且，端口#E与端口#F所包括的端口不同。
下面，对第二级EPDCCH(即，第二级专用信道的一例)的时频资源的配置方式进行详细说明。
可选地，该第二级专用信道的时频资源属于至少两个资源块RB。
具体地说，第二级EPDCCH的时频资源的分配可以以RB为单位，即，第二级EPDCCH的时频资源可以属于至少两个RB，需要说明的是，“属于至少两个RB”是指，该第二级EPDCCH的时频资源可以包括至少两个RB的全部时频资源，也可以包括该至少两个RB的部分时频资源，例如，包括每个RB的一半数量的子载波或符号。
可选地，该第二级专用信道的时频资源所属于的至少两个RB非连续。
具体地说，第二级EPDCCH的时频资源可以承载于不相邻的至少两个RB中。从而，能够提高传输的分集增益。
可选地，该第二级专用信道的时频资源在频域上位于预先规定的带宽的两端。
具体地说，第二级EPDCCH的时频资源可以属于预先规定的带宽两端的至少两个RB。
并且，在本发明实施例中，该预先设定的带宽是指网络设备和终端设备预先约定的带宽，作为示例而非限定，该预先设定的带宽可以是通信系统所使用的系统带宽。
可选地，该第二级专用信道的时频资源所属于的至少两个RB连续，其中，属于第三RB的该第二级专用信道的时频资源与属于第四RB的该第二 级专用信道的时频资源非连续。
具体地说，第二级EPDCCH的时频资源可以属于至少两个RB，并且，该至少两个RB中，只有部分(例如，一半数量)的子载波被用于作为第二级EPDCCH的时频资源。并且，当第二级EPDCCH的时频资源可以所属于两个RB相邻时，这两个RB中被用于作为第二级EPDCCH的时频资源的子载波不连续。
可选地，该第二级专用信道的时频资源包括同一传输时间间隔TTI的前K个符号，K≥1。
具体地说，第二级EPDCCH的时频资源可以为所属于的RB的前K个符号，并且该RB的剩余符号可以作为例如，PDSCH的时频资源。
应理解，以上列举的一个RB内除作为第二级EPDCCH的时频资源以外的符号的作用仅为示例性说明，本发明并未特别限定，例如，图6示出了第二级EPDCCH的时频资源的分布方式的另一例的示意图，如图6所示，分配给一个终端设备的第二级EPDCCH的时频资源可以为所属于的RB的前K个符号，并且该RB的剩余符号可以作为例如，分配给另一个终端设备的第二级EPDCCH的时频资源。
并且，上述K的具体数值可以根据需要任意确定，作为示例而非限定，例如，当一个RB包括7个符号时，第二级EPDCCH的时频资源可以为所属于的RB的第1个符号，或，前4个符号。
可选地，该网络设备为该目标终端设备分配第一级专用信道和第二级专用信道，包括：
根据该目标终端设备所访问的业务的时延要求，为述目标终端设备分配第二级专用信道。
具体地说，例如，当终端设备所访问的业务对时延要求较高时，终端设备无需检测一个RB的所有符号，便能够通过第二级专用EPDCCH的时频资源，获得调度信息，从而能够加快针对该终端设备的调度速度，减少终端设备的业务访问时延。
可选地，该第二级专用信道的时频资源属于同一TTI中的M个资源块RB，M≥1。
具体地说，第二级EPDCCH的时频资源可以为一个TTI所属于的RB的M个RB，并且该TTI中剩余的RB可以作为例如，PDSCH的时频资源。
并且，上述M的具体数值可以根据需要任意确定，本发明并未特别限定。
可选地，该第二级专用信道包括第一TTI内的至少一个信道单元CE。
具体地说，在本发明实施例中，该第二级专用信道(具体地说，是该第二级专用信道的时频资源)可以以信道单元(CE，Channel Element)为单位进行划分，即，该第二级专用信道可以包括一个TTI(即，第一TTI的一例)中的至少一个CE。
可选地，该第二级专用信道的时频资源在该第一TTI内集中式配置或分布式配置，其中，
分布式配置是指：当该第一TTI内的被分配给该第二级专用信道的RB仅用于承载该第二级专用信道时，每个该CE的时频资源属于该第一TTI内的至少两个RB，或
当该第一TTI内的被分配给该第二级专用信道的RB用于承载该第二级专用信道和其他信道时，每个该CE所包括的资源单元RE在频域上非连续；
集中式配置是指：当该第一TTI内的被分配给该第二级专用信道的RB仅用于承载该第二级专用信道时，每个该CE的时频资源属于该第一TTI内的同一RB，或
当该第一TTI内的被分配给该第二级专用信道的RB用于承载该第二级专用信道和其他信道时，每个该CE所包括的资源单元RE在频域上连续。
具体地说，在本发明实施例中，第二级专用信道可以集中式配置在同一TTI中，或者，第二级专用信道也可以分布式配置在同一TTI中。
首先，对分布式配置的情况进行详细说明。
在本发明实施例中，该第二级专用信道可以与其他信道采用频分复用方式复用同一TTI内的各RB，即，在一个TTI内的被分配给第一专用信道的RB仅用于承载第二级专用信道，而不能用于承载其他信道(例如，PDSCH)。
此情况下，如果第二级专用信道包括同一TTI内的一个或多个CE，并且，每个CE可以属于至少两个RB，则可以认为第二级专用信道分布式配置在该TTI中。
如图7所示，网络设备分配给一个终端设备的CE(例如，CE#1，可以用于承载第二级专用信道)可以属于至少两个RB，进一步，该CE可以包括至少两个RB的部分时频资源，例如，包括每个RB的部分符号，并且， 同一RB的剩余符号可以分配给其他终端设备的CE。
或者，网络设备分配给一个终端设备的CE可以属于至少两个RB，并且该CE可以包括至少两个RB的部分时频资源，例如，包括每个RB的部分子载波。
需要说明的是，图7中所示的CE#1～CE#4可以分别被分配给多个终端设备而分别作为多个终端设备的第二级专用信道。
或者，图7中所示的CE#1～CE#4中的部分或全部CE也可以被分配给多同一终端设备而分别作为一个终端设备的第二级专用信道。
在第二级专用信道与其他信道采用频分复用方式复用同一TTI时，通过使第二级专用信道包括一个或多个CE，并使每个CE的时频资源属于至少两个RB中，能够使第二级专用信道分布式(或者说，分散地)配置在系统带宽中，从而能够有效增加分集增益，进一步提高本发明的可靠性和实用性。
在本发明实施例中，该第二级专用信道可以与其他信道采用时分复用方式复用同一TTI内的各RB，例如，如图5所示，在一个TTI内的被分配给第一专用信道的RB中的部分符号用于承载第二级专用信道，同一RB中的其他符号可以其他信道(例如，PDSCH)。
此情况下，如果第二级专用信道包括同一TTI内的一个或多个CE，并且，每个CE所包括的资源单元(RE，Resource Element)不连续，则可以认为第二级专用信道分布式配置在该TTI中。
如图8所示，网络设备分配给一个终端设备的CE(例如，CE#1)可以属于同一TTI中的部分(例如，2个RB)，进一步，该CE可以包括2个RB的部分符号(例如，第一个符号)，同一RB的剩余符号可以分配给其他信道(例如，PDSCH)。
在第二级专用信道与其他信道采用时分复用方式复用同一TTI时，通过使第二级专用信道包括一个或多个CE，并使每个CE所包括的RE非连续，能够使第二级专用信道分布式(或者说，分散地)配置在系统带宽中，从而能够有效增加分集增益，进一步提高本发明的可靠性和实用性。
下面，对集中式配置的情况进行详细说明。
在本发明实施例中，该第二级专用信道可以与其他信道采用频分复用方式复用同一TTI内的各RB，即，在一个TTI内的被分配给第一专用信道的RB仅用于承载第二级专用信道，而不能用于承载其他信道(例如，PDSCH)。
此情况下，如果一个第二级专用信道包括同一TTI内的一个或多个CE，并且，并且，每个CE的时频资源可以属于同一RB，则可以认为该第二级专用信道集中式配置在该TTI中。
如图9所示，网络设备分配给一个终端设备的CE(用于承载该终端设备的第二级专用信道)可以属于同一RB。并且，该分配给一个终端设备的CE可以仅占用一个RB中的部分符号或部分子载波，其他的符号或子载波可以被分配给其他终端设备，而作为其他终端设备的第二级专用信道的时频资源。
需要说明的是，图9中所示的CE#1～CE#4可以分别被分配给多个终端设备而分别作为多个终端设备的第二级专用信道。
在第二级专用信道与其他信道采用频分复用方式复用同一TTI时，通过使第二级专用信道包括一个或多个CE，并使每个CE的时频资源属于同一RB中，能够使第二级专用信道集中式(或者说，集中地)配置在系统带宽中，从而能够根据信道的干扰情况，选择信道质量较好的信道集中配置第二级专用信道，进一步提高本发明的可靠性和实用性。
在本发明实施例中，该第二级专用信道可以与其他信道采用时分复用方式复用同一TTI内的各RB，例如，如图5所示，在一个TTI内的被分配给第一专用信道的RB中的部分符号用于承载第二级专用信道，同一RB中的其他符号可以其他信道(例如，PDSCH)。
此情况下，如果第二级专用信道包括同一TTI内的一个或多个CE，并且，每个CE所包括的资源单元(RE，Resource Element)连续，则可以认为第二级专用信道集中式配置在该TTI中。
如图10所示，网络设备分配给一个终端设备的CE(例如，CE#1)可以属于同一TTI中的全部RB，进一步，该CE可以包括同一TTI中的全部RB的部分符号(例如，第一个符号)，同一RB的剩余符号可以分配给其他信道(例如，PDSCH)。
在第二级专用信道与其他信道采用时分复用方式复用同一TTI时，通过使第二级专用信道包括一个或多个CE，并使每个CE所包括的RE连续，能够使第二级专用信道集中式(或者说，集中地)配置在系统带宽中，从而能够根据信道的干扰情况，选择信道质量较好的信道集中配置第二级专用信道，进一步提高本发明的可靠性和实用性。
应理解，以上列举的时频资源的分布方式仅为示例性说明，本发明并未限定于此，也可以根据需求进行调整。
另外，如图3至图10所示，第二级专用信道中还可以包括用于承载参考信道(或者说，导频信号)的时频资源。
并且，在本发明实施例中，每个端口可以独立的占用一个时频资源，例如，图3至图7中所示的端口，例如，端口#1～端口#4，或端口#A～端口#D中的任意端口，可以为一个端口。
或者，在本发明实施例中，多个端口可以复用同一时频资源，例如，图8至图10中所示的端口，例如，端口#E可以包括多个(例如，4个)端口，或者，图10中端口#F可以包括多个(例如，4个)端口，并且，端口#E与端口#F所包括的端口不同。

该第一配置图案是，该第一级专用信道的每个该CE中用于传输参考信号的时频资源该的配置图案；
该第二配置图案是，该第二级专用信道的每个该CE中用于传输参考信号的时频资源该的配置图案。
具体地说，在本发明实施例中，第一级专用信道(例如，第一级EPDCCH)中用于承载参考信号(或者说，导频信号)的时频资源的配置图案可以与第二级专用信道(例如，第二级EPDCCH)中用于承载参考信号(或者说，导频信号)的时频资源的配置图案相同。
可选地，第三配置图案与第四配置图案相异，其中，

该第四配置图案是，当该第二级专用信道的时频资源在该第一TTI内分布式配置该时，该第二级专用信道的每个该CE中用于传输参考信号的时频资源的配置图案。
需要说明的是，在本发明实施例中，上述CE可以是控制信道单元CCE(Control Channel Element)，也可以是增强的控制信道单元(ECCE，Enhanced Control Channel Element)还可以是其他类型的控制信道单元，本发明并未特别限定。
图11示出了第一级专用信道、第二级专用信道和下行数据信道的配置方式的一例的示意图。如图11所示，在本发明实施例中，专用信道(包括第一级和第二级专用信道)和部分下行数据信道可以采用时分复用的方式配置，另外，专用信道和另一部分下行数据信道可以采用频分复用的方式配置，并且第一级专用信道和第二级专用信道可以采用频分复用方式配置。
应理解以上列举的第一级专用信道、第二级专用信道和下行数据信道的配置方式仅为示例性说明，本发明并未限定于此。
可选地，该通信系统还包括公共信道，该公共信道的时频资源与该专用信道的时频资源不同，其中，该公共信道被该通信系统中的所有终端设备检测，该方法还包括：

其中，该公共消息包括随机接入响应消息、寻呼消息或系统消息中的至少一种。
这里，“公共信道”可以被系统中的各终端设备检测。
另外，“公共消息”可以是网络设备通过例如广播形式发送给系统内的各终端设备的消息，作为示例而非限定，上述“公共消息”可以包括现有中需要通过在PDCCH的公共搜索区域传输给各终端设备的消息，例如，系统消息、如随机接入响应消息或寻呼消息等。
可选地，该公共信道为公共的增强的下行控制信道EPDCCH信道。
具体地说，在本发明实施例中，通信系统中的EPDCCH可以分为专用的EPDCCH和公用的EPDCCH，“公共的EPDCCH”是指被系统中的所有终端设备检测的EPDCCH。
应理解，以上列举的以EPDCCH作为专用信道的方案仅为示例性说明，本发明并未限定于此，例如，还可以使用下一代增强的下行控制信道(英文全称可以为：Future Enhanced Physical Downlink Control Channel，英文简称可以为：FEPDCCH)或公共的PDCCH作为公共信道。
网络设备可以根据预设的用于传输系统信息(例如，MIB)的时频资源 (即，第二时频资源的一例)向终端设备下发公共信道的时频资源的指示信息，从而，系统内的终端设备可以通过上述预设的时频资源，获取公共信道的时频资源的指示信息，从而确定公共信道的时频资源。
例如，网络设备可以通过公共信道发送上述公共消息，从而，终端设备可以在公共信道的时频资源上进行接收处理(或者说，搜索处理)，以获取上述公共消息。
或者，网络设备可以通过公共信道发送PDSCH中的某一时频资源的指示信息，并在该PDSCH中的时频资源上发送公共消息，从而，终端设备可以通过公共信道获取该PDSCH中的时频资源的指示信息，进而确定PDSCH中用于承载公共消息的时频资源，并在该时频资源上进行接收处理，以获取上述公共消息。
需要说明的是，在本发明实施例中，公共信道(例如，公共EPDCCH)的时频资源的指示信息和第一级专用信道(例如，第一级EPDCCH)的时频资源的指示信息可以通过相同的消息发送也可以通过不同的消息发送本发明并未特别限定。
并且，在本发明实施例中，公共EPDCCH的时频资源的分布方式可以与上述第一级EPDCCH的时频资源的分布方式(例如，图3至图8所示方式)相似，这里，为了避免赘述，省略其详细说明，即：

并且，由于第一级专用信道和第二级专用信道均至被分配给一个终端设备，从而，能够使本发明的传输调度信息的方法适用于多输入多输出(MIMO，Multiple-Input Multiple-Output)传输的场景。
