具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
参见图1，图1为本公开实施例提供的网络结构的示意图。该网络结构包括一个或多个用户终端(UE，User Equipment)11和基站12，在图1中以多个UE 11进行举例示意。UE 11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，简称PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端设备。需要说明的是，本公开实施例并不限定UE 11的具体类型。UE 11可以与基站12建立通信，图1中的网络可以表示UE 11与基站12建立的无线通信。基站12可以是演进型基站(eNB，evolved Node B)或者其他基站。需要说明的是，本公开实施例并不限定基站12的具体类型。
基于图1所示的网络结构，本公开实施例提供一种下行控制信息传输方法。该方法可以由基站执行，但本发明不局限于此。如图2所示，该下行控制信息传输方法包括以下步骤S201至S202。
S201：确定在下行传输时段内的TTI中为UE预留的下行控制信道资源，其中，下行控制信道资源为该TTI中的特定频域资源，该TTI包括N个OFDM符号，N为大于或者等于1的正整数。
S202：在该下行控制信道资源上使用下行控制信道向UE传输下行控制信息。
在本实施例中，下行控制信道资源可以是TTI包括的频域资源中的部分频域资源，例如下行控制信道资源可以是TTI包括的一个或者多个符号中包 括的频域资源中的部分频域资源。当然，在一些场景中也不排除该下行控制信道资源可以是TTI的所有频域资源，本实施例对此不作限定。另外，步骤S201确定下行控制信道资源可以理解为确定在该TTI内为UE预留的下行控制信道资源的位置，因为在TTI内每个频域资源都存在特定位置，所以确定频域资源可以理解为确定该频域资源在TTI中的位置。另外，为UE预留的下行控制信道资源可以是在执行步骤S201时为UE预留的下行控制信道资源，或者可以是预先在TTI中为UE预留的下行控制信道资源，再由步骤S201确定出等等，本实施例对此不作限定。
另外，下行控制信道资源所占的时域资源可以等于或者小于TTI所占的时域资源。TTI包括N个OFDM符号可以理解为TTI可以是一个或者多个OFDM。具体地，TTI包括N个OFDM符号还可以理解为TTI由N个OFDM符号组成。通过这种可变的TTI可以使本实施例中的下行控制信息传输方法支持未来丰富的业务类型。
另外，本公开实施例中提到的下行控制信道资源可以为用于下行控制信道传输的频域资源。
在本实施例中，下行控制信道可以是PDCCH，下行控制信息是调度信息或者其他控制信息，本实施例对此不作限定。
在本实施例中，该方法还可以应用于图1所示的网络结构中的基站12，即基站12可以实现该方法。
本公开实施例，在下行传输时段内的TTI中为UE预留的下行控制信道资源上使用下行控制信道向UE传输下行控制信息。该TTI包括N个OFDM符号，N为大于或者等于1的正整数。这样可以实现TTI的长度可变，且还可以在TTI的下行控制信道资源上使用下行控制信道传输下行控制信息，从而可以更好地支持未来丰富的业务类型。
参阅图3，图3是本公开实施例提供的下行控制信息传输方法的另一示例的流程图。该方法的另一示例可以由基站执行，但本发明不局限于此。如图3所示，该下行控制信息传输方法包括以下步骤S301至S303。
S301：确定在下行传输时段内的TTI中为UE预留的下行控制信道资源，其中，下行控制信道资源为用于下行控制信道传输的频域资源，该TTI包括 N个OFDM符号，N为大于或者等于1的正整数。
S302：在该下行控制信道资源上使用下行控制信道向UE传输下行控制信息。
可选的，下行控制信道资源可以是UE专属的下行控制信道资源，TTI内还包括为其他UE预留的下行控制信道资源，其中，TTI内为每个UE预留的下行控制信道资源不同。
在该实施方式中，可以实现在TTI内为多个UE预留的下行控制信道资源。这样在一些场景中可以在同一个TTI内向多个UE发送下行控制信息。另外，TTI内为多个UE预留下行控制信道资源可以理解为在TTI内为每个UE预留的下行控制信道资源的位置不同。其中，其他UE可以是除该UE之外的一个或者多个UE。
可选的，下行控制信道资源可以是为包括该UE在内多个UE预留的下行控制信道资源，其中，下行控制信道资源内的下行控制信道根据每个UE的RNTI来区分。
该实施方式中，可以实现多个UE共享相同下行控制信道资源，这样可以节省下行控制信息传输的开销。当然，这里预留的下行控制信道资源可以是一个或多个下行控制信道资源。下行控制信道资源可以包括多个控制信道单元(Control Channel Element(CCE))，这样在该下行控制信道资源内，可以根据各UE的RNTI区分每个UE的下行控制信道，以在不同的下行控制信道中发送下行控制信息，而每个UE可以根据各自的RNTI区分自己的下行控制信道，从而在该下行控制信道对应的CCE上进行盲检以获得基站发送的下行控制信息。另外，多个UE可以是所有UE或者一组UE。
可选的，TTI中预留的下行控制信道资源在不需要传输下行控制信息时用于下行数据传输。
该实施方式中，可以实现将在下行传输时段内的TTI中不需要传输下行控制信息的下行控制信道资源用于传输下行数据，即基站可以在不需要传输下行控制信息的下行控制信道资源上向UE传输下行数据，从而可以节省网络传输资源。因为在一些场景中，在下行传输时段内并不是所有预留的下行控制信道资源都需要传输下行控制信息。当然，在一些场景中，如果基站需 要向其他UE发送下行数据，当为UE预留的下行控制信道资源不需要发送下行控制信息时，基站可以在该预留的下行控制信道资源上向其他UE传输下行数据。
可选的，下行控制信息可以包括UE的下行数据传输资源的调度信息，方法还包括步骤S303。
S303：在由调度信息调度的下行数据传输资源上向UE传输下行数据。
其中，下行数据传输资源可以理解为向UE传输下行数据的数据区域。另外，下行数据传输资源可以包括步骤301的TTI中的部分资源。例如：步骤301中的TTI中除为UE预留的下行控制信道资源之外的所有资源都可以作为下行数据传输资源。另外，下行数据传输资源可以包括一个或多个TTI中的资源。例如：下行数据传输资源可以包括步骤301的TTI中除为UE预留的下行控制信道资源之外的所有资源，以及在该TTI之后一个或多个TTI的资源。
可选的，下行数据传输资源可以包括为其他UE预留的下行控制信道资源，其中，在下行数据传输资源包括的为其他UE预留的下行控制信道资源上禁止发送下行控制信息。
该实施方式中，可以实现使用为其他UE预留的下行控制信道资源向UE发送下行数据，从而可以节省传输资源。另外，在使用为其他UE预留的下行控制信道资源向UE发送下行数据时，基站不能在下行数据传输资源包括的为其他UE预留的下行控制信道资源中传输其他UE的下行控制信息。
可选的，下行数据传输资源可以不包括为其他UE预留的下行控制信道资源。
该实施方式中，可以实现在为UE调度的下行数据传输资源中不包括为其他UE预留的下行控制信道资源，即在向UE传输下行数据时不占用为其他UE预留的下行控制信道资源，这样可以不影响其他UE的下行控制信息的传输。具体实现可以通过调度来限制，以避免调度的下行数据传输资源包含为其他UE所预留的下行控制信道资源。
可选的，下行数据传输资源可以不包括为其他UE预留的需要发送下行控制信息的下行控制信道资源。
该实施方式中，可以实现为UE调度的下行数据传输资源中不包括为其他UE预留的需要发送下行控制信息的下行控制信道资源，即在向UE传输下行数据时不占用为其他UE预留的需要发送下行控制信息的下行控制信道资源，这样可以不影响其他UE的下行控制信息的传输。其中，这里需要发送的可以在下行传输时段内发送的下行控制信息。具体实现可以通过调度来限制。当需要使用其他UE的下行控制信道资源时，避免下行数据传输资源包含为其他UE所预留的下行控制信道资源。
可选的，下行数据传输资源可以包括为其他UE预留的不需要发送下行控制信息的下行控制信道资源。
该实施方式中，可以实现下行数据传输资源包括为其他UE预留的不需要发送下行控制信息的下行控制信道资源，即向UE发送下行数据时可以占用为其他UE预留的不需要发送下行控制信息的下行控制信道资源，从而可以节省传输资源。其中，不需要发送下行控制信息可以理解为在下行传输时段内不需要发送下行控制信息。
可选的，下行数据传输资源不包括为其他UE预留的需要发送下行控制信息的下行控制信道资源，但包括为其他UE预留的不需要发送下行控制信息的下行控制信道资源。
该实施方式中，可以实现在下行数据传输资源中不包括需要发送下行控制信息的下行控制信道资源，但包括不需要发送下行控制信息的下行控制信道资源，从而可以节省传输资源以及避免影响其他UE的下行控制信息传输。具体实现可以通过调度来限制。当需要使用其他UE的下行控制信道资源时，避免下行数据传输资源包含为其他终端所预留的下行控制信道资源，当不需要使用其他UE的下行控制信道资源时，可以将这部分资源作为下行数据传输资源分配给UE进行下行数据传输。
可选的，该方法还可以包括如下步骤：向UE发送通知消息，该通知消息用于通知下行数据传输资源是否存在不发送下行数据的资源，以使UE在下行数据传输资源存在不发送下行数据的资源时，在下行数据传输资源中除不发送下行数据的资源之外的资源上接收下行数据，和以使UE在下行数据传输资源不存在不发送下行数据的资源时，在下行数据传输资源中的所有资 源上接收下行数据。
其中，该通知消息可以是在下行控制信道资源上传输的，还可以是与下行控制信息一起传输的，本实施例对此不作限定。另外，该通知消息可以通知在为UE配置的下行数据传输资源中是否包含为其他UE预留的下行控制信道资源和/或是否需要预留其他UE的下行控制信道资源。即该通知消息可以通知下行数据传输资源是否包括为其他UE预留的下行控制信道资源，以及还可以通知是否需要预留这些下行控制信道资源，其中需要预留下行控制信道资源可以理解为该下行控制信道资源需要发送下行控制信息，从而在该下行控制信道资源中不发送下行数据。
例如：通知消息可以用1个比特通知是否包含。如果包含，则基站在为UE分配的下行数据传输资源中包含的为其他UE预留的下行控制信道资源中不传输该UE的下行数据。UE可以通过公共(common)的下行控制信道资源定义，确定在其被调度的下行数据传输资源中的除了下行控制信道资源以外的资源上接收下行数据。进一步，如果采用UE专属的下行控制信道资源划分方式，基站还可以通过下行控制信道通知UE，以让UE可以获得其他UE的下行控制信道资源的参数，如其他UE的RNTI。这样UE可以根据其他UE的RNTI确定包含在下行数据传输资源中的其他UE的下行控制信道资源，从而在下行数据传输资源中的除了其他UE终端的下行控制信道资源以外的资源上接收下行数据。如果不包含，则基站按照为UE所分配的下行数据传输资源传输下行数据，UE按照被分配的下行数据传输资源接收下行数据。
又例如，通知消息可以使用M个比特通知其他UE的下行控制信道资源的参数，如其他UE的RNTI，如果该参数为特定状态，例如全0，则表示下行数据传输资源中不包含其他UE的下行控制信道资源，否则表示下行数据传输资源中包含其他UE的下行控制信道资源，其中M为大于或者等于1的正整数。当指示包含时，基站在为UE分配的下行数据传输资源中包含的其他UE的下行控制信道资源中不传输该UE的下行数据。此时，该UE可以根据通知的RNTI隐式计算得到该UE被分配的下行数据传输资源中包含的其他UE的下行控制信道资源。如果不包含，则基站按照为UE分配的下行数据传输资源中传输下行数据，UE按照分配的下行数据传输资源接收下行数据。
可选地，步骤S303可以包括：在由调度信息调度的下行数据传输资源上向UE传输由特定RNTI加扰的下行数据。
其中，特定RNTI可以是基站与UE预先协商好的，例如UE的RNTI或者其他特定的RNTI。在UE接收到下行数据后，就可以使用该特定RNTI进行解扰，以获得下行数据。
该实施方式中，可以提高数据的安全性。
可选的，下行传输时段内每个TTI都可以存在为UE预留的下行控制信道资源。若下行数据传输资源中存在为UE预留的下行控制信道资源，则在该下行数据传输资源中为UE预留的下行控制信道资源中不发送下行控制信息。
该实施方式中，可以实现在下行数据传输资源内不发送UE的下行控制信息。这样，UE在该下行数据传输资源内的下行控制信道资源中不需要进行盲检，以节省UE的功耗。另外，下行传输时段内每个TTI还都可以包括其他UE的下行控制信道资源。
例如：在下行传输时间段中，假设最小TTI包含2个OFDM符号，每个TTI上均存在为UE预留的下行控制信道资源，但下行控制信道资源所占的时域资源小于最小TTI的长度，即下行控制信道所占的时域资源小于最小TTI的长度，如在时域上只占1个OFDM符号。当基站需要调度下行数据传输时，则需要在所调度的UE的下行控制信道资源上发送下行控制信息。UE需要在每个TTI上为自己预留的下行控制信道资源上进行盲检，当然，在UE的下行数据传输资源中包括的TTI中不需要进行盲检。如果UE在自己的下行控制信道资源上盲检获得自己的调度信息，则根据该调度信息获得下行数据传输资源，以在该资源上接收下行数据。其中，该调度信息可以调度同一个TTI上的部分或者所有资源，也可以调度多个TTI上的部分或者全部频域资源。基站在该下行数据传输资源内不再为其他UE分配下行控制信息。其他UE仍然需要在为自己预留的下行控制信道资源上尝试盲检下行控制信息。假设基站内共有两个UE，下行数据传输时间段内共有8个OFDM符号，具体示例如图4所示，其中，标号1和标号2对应于UE1，标号3对应于UE2。通过图4可知，基站在标号1和标号2的下行控制信道资源发送UE1的下行控 制信息，在标号1和标号2的下行数据传输资源发送UE1的下行数据，在基站在标号3的下行控制信道资源发送UE2的下行控制信息，并且在标号3的下行数据传输资源发送UE2的下行数据。如图4所示，UE1的下行数据传输资源占用两个TTI。这样如图5所示，UE1只需要在501、502和503所示的下行控制信道资源上进行盲检，而不需要在504所示的下行控制信道资源盲检，但UE2需要在下行控制信道资源505、506、507和508都需要进行盲检。
又例如，在下行传输时间段中，假设最小TTI包含2个OFDM符号，每个TTI上均存在为UE预留的下行控制信道资源，但下行控制信道资源所占的时域资源等于最小TTI的长度，如在时域上只占2个OFDM符号。当基站需要调度下行数据传输时，需要在所调度的UE的下行控制信道资源上发送下行控制信息。UE需要在每个TTI上为自己预留的下行控制信道资源上进行盲检，当然在UE的下行数据传输资源中包括的TTI中不需要进行盲检。如果UE在自己的下行控制信道资源上盲检获得自己的调度信息，则根据该调度信息获得下行数据传输资源，以在该资源上接收下行数据。该调度信息可以调度同一个TTI上的部分或者所有资源，也可以调度多个TTI上的部分或者全部频域资源。基站在该下行数据传输资源内不再为其他UE分配下行控制信息。其他UE仍然需要在为自己预留的下行控制信道资源上尝试盲检下行控制信息。假设基站内共有两个UE，下行数据传输时间段内共有8个OFDM符号，具体示例如图6所示，其中，标号1和标号2对应于UE1，标号3对应于UE2。如图6所示，基站在标号1和标号2的下行控制信道资源发送UE1的下行控制信息，以及在标号1和标号2的下行数据传输资源发送UE1的下行数据，在基站在标号3的下行控制信道资源发送UE2的下行控制信息，在标号3的下行数据传输资源发送UE2的下行数据。如图6所示，UE1的下行数据传输资源占用两个TTI。这样，如图7所示，UE1只需要在701、702和703所示的下行控制信道资源上进行盲检，而不需要在704所示的下行控制信道资源盲检，但UE2需要在下行控制信道资源705、706、707和708都需要进行盲检。
可选的，当下行传输时段内的前H个TTI存在为UE预留的下行控制信道资源，且除前H个TTI之外的所有TTI都不存在为UE预留的下行控制信 道资源时，若下行数据传输资源中存在为UE预留的下行控制信道资源，则在下行数据传输资源中为UE预留的下行控制信道资源中不发送下行控制信息，其中，H为大于或者等于1的整数。
该实施方式中，可以实现只有下行传输时段内的前H个TTI中存在为UE预留的下行控制信道资源，其他TTI中不存在下行控制信道资源。例如：只有下行传输时段内的第一个TTI中存在为UE预留的下行控制信道资源，其他TTI中不存在下行控制信道资源。这样可以减少UE盲检的资源，以节省UE功耗。同样的，也可以是只有前H个TTI中存在为其他UE预留的下行控制信道资源。
例如：在下行数据传输时间段内只在第一个TTI上为UE预留下行控制信道资源。即基站只在下行传输时间段内的第一个TTI上发送下行控制信息。UE只需要在下行传输时间段内的第一个TTI上和自己的下行控制信道资源上尝试盲检下行控制信息。基站可以在第一个TTI上发送所有或者部分UE的下行控制信息。没有发送下行控制信息的资源可以用于发送下行数据。UE需要在自己的下行控制信道资源上尝试盲检下行控制信息，无论基站是否在该资源上发送了下行控制信息。假设归属于基站的UE数目为四个，假设最小TTI长度为1个OFDM符号，基站传输下行控制信息和下行数据如图8所示，那么，UE1-UE4进行的盲检如图9所示，即UE1-UE4都只在第一个TTI中进行盲检。
可选的，在下行传输时段内存在为UE预留的下行控制信道资源的多个TTI彼此相隔M个TTI。当下行数据传输资源中存在为UE预留的下行控制信道资源时，在下行数据传输资源中为UE预留的下行控制信道资源中不发送下行控制信息，其中，M为大于或者等于1的正整数。
该实施方式中，可以实现相隔M个TTI发送下行控制信息。这样，UE只需要相隔M个TTI进行一次盲检，以节省UE功耗。同样，存在为其他UE预留的下行控制信道资源的多个TTI彼此也可以是相隔M个TTI。
例如：下行传输时间段内，存在下行控制信道资源的两个TTI间相隔M个TTI。在存在下行控制信道资源的TTI上，每个UE的下行控制信道资源可以是预先定义好的。UE在每个存在下行控制信道资源的TTI中的自己的下行 控制信道资源上尝试盲检下行控制信息。当预定义的下行控制信道资源没有下行控制信息需要发送时，该预定义的下行控制信道资源可用于下行数据的传输。某个TTI上的下行控制信息调度的下行数据传输资源要包含下一个存在下行控制信道资源的TTI。如果在某个TTI上UE的下行控制信息中调度的下行数据传输资源包含下一个存在下行控制信道资源的TTI，则该UE在下一个存在下行控制信道资源的TTI上不需要盲检下行控制信息。假设M为3，归属于该基站的UE数目为3，最小TTI长度为1个OFDM符号，则基站传输的下行控制信息和下行数据的示意如图10所示。由于UE1的下行数据传输资源占用了下行传输时段内的所有TTI，所以如图11所示，UE1只需要在下行控制信道资源111进行盲检，而在下行控制信道资源112不需要进行盲检，而UE2需要在下行控制信道资源113和114进行盲检，UE3需要在下行控制信道资源115和116进行盲检。
可选的，步骤S301可以包括：根据UE的RNTI和TTI在下行传输时段中的编号确定TTI中为UE预留的下行控制信道资源。
该实施方式中，可以实现根据UE的RNTI和TTI的编号确定下行控制信道资源。具体可以是预先获取RNTI和TTI在下行传输时段中的编号与下行控制信道资源的对应关系，当然，本实施例中对此不作限定。例如：还可以将UE的RNTI和TTI的编号进行特定运算，要根据运算结果确定下行控制信道资源等。从而，基站可以根据该对应关系确定下行控制信道资源。同理，UE也可以根据UE的RNTI和TTI在下行传输时段中的编号确定下行控制信道资源。
需要说明的是，本实施例中介绍的多种可选的实施方式可以相互结合实现，也可以单独实现。这里以通知消息的实现方式与下行传输时段内每个TTI都存在为UE预留的下行控制信道资源的实现方式结合实现为例，进行举例说明，具体如下。
例如：在下行数据传输时间段中，假设最小TTI包含2个OFDM符号。每个TTI上均存在为UE预留的下行控制信道资源，且下行控制信道资源所占的时域资源等于最小TTI的长度。当基站需要调度下行数据传输时，需要在所调度的UE的下行控制信道资源上发送下行控制信息。UE需要在每个 TTI上的为自己预留的下行控制信道资源上盲检下行控制资源。如果UE盲检获得自己的调度信息，则UE根据该调度信息确定下行数据传输资源，并在该下行数据传输资源上接收下行数据。该下行数据传输资源是同一个TTI上的部分或者所有资源，也可以是多个TTI上的部分或者全部频域资源。其中，UE在下行数据传输资源包含的为自己预留的下行控制信道资源上不再盲检下行控制信息。基站在第一个TTI中的下行数据传输资源中包含的为其他UE预留的下行控制信道资源上分配下行控制信息，并在第一个TTI中的UE的下行控制信息中用1比特告知该UE在基站为其他UE预留的下行控制信道资源上不能传输下行数据。进一步的，如果每个UE都配置下行控制信道资源，则还需要通知UE为其他全部或者部分UE预留的控制信道资源的位置信息。其他UE需要在为自己预留的下行控制信道资源上尝试盲检下行控制信息。假设基站内共有两个UE，下行传输时间段内共有8个OFDM符号，则具体示例如图12所示，基站在标号1和标号2的下行控制信道资源上传输UE1的下行控制信息，在标号1、标号2和标号3的下行数据传输资源上传输UE1的下行数据，这里需要说明的是，标号1的下行数据传输资源包括UE2的下行控制信道资源，从而这里可以跳过UE2的下行控制信道资源，因为这里的下行控制信道资源此时需要传输UE2的下行控制信息。但标号2的下行数据传输资源包括UE2的下行控制信道资源，这里可以不跳过UE2的下行控制信道资源，因为这里的下行控制信道资源此时不需要传输UE2的下行控制信息。在标号3的下行控制信道资源上传输UE2的下行控制信息，以及在标号4和标号5的下行数据传输资源上传输UE2的下行数据。这样UE1和UE2的盲检就可以如图13所示，UE1在下行控制信道资源131、132、133和134进行盲检，UE2在下行控制信道资源135、136、137和138进行盲检。
本实施例中，在图2所示的实施例的基础上增加了多种可选的实施方式，且都可以实现更好地支持未来丰富的业务类型。
