Description

一种下行控制信道传输方法及设备 技术领域
本发明涉及通信技术领域，尤其涉及一种下行控制信道传输方法及设备。
背景技术
在长期演进(Long Term Evolution，LTE)标准中，一般认为一个传输时间间隔(Transmission Time Interval，TTI)的时间长度为1ms，即一个子帧(subframe，SF)的大小，即1TTI＝1ms＝1SF。其中，1SF包含2个时隙(Slot)。如图1所示，在LTE通信***中用于下行传输的子帧上，一个TTI可以划分为：用于传输物理下行控制信道的控制区域和用于传输物理下行数据信道的数据区域，其中，物理下行控制信道用于承载物理下行数据信道的控制信息。
其中，为了缩短数据的传输往返时间(Round-Trip Time，RTT)和数据的传输时延，业界提出了一种设置TTI＝0.5ms与1TTI＝1ms兼容进行数据传输的方案，即如图2所示，将原有的1个Normal TTI(简称：N-TTI)划分为分别对应于1SF中的2个时隙(时隙0和时隙1)的2个Shorten TTI(简称：S-TTI)。其中，数据的RTT为从发送方发送数据开始，到发送方接收到接收方的确认指示后，下一个时刻为此发送方再次向此接收方发送数据截止的时间。
如图2所示，N-TTI可以划分为：控制区域(阴影部分)和数据区域(非阴影部分)。在上述TTI＝0.5ms与1TTI＝1ms兼容进行数据传输的方案中，由于时隙0所对应的S-TTI(S-TTI 0)与N-TTI的控制区域重合，因此，S-TTI 0可以复用N-TTI的控制区域，以作为S-TTI 0的控制区域，传输S-TTI 0中的PDCCH；但是，存在的问题是，时隙1所对应的S-TTI(S-TTI 1)处于N-TTI的数据区 域的，该部分原来是用于传输N-TTI中的物理下行数据信道的，S-TTI-1是无法复用N-TTI的控制区域的。此时，用户设备不知道从哪些控制区域去接收S-TTI-1的物理控制信道；由于无法确定S-TTI-1的控制区域，则无法通过S-TTI-1的控制区域传输TTI-1的物理控制信道，进而则无法进行S-TTI-1的物理数据信道的传输。

基站(例如，接入点)可以是接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。基站还可协调对空中接口的属性管理。例如，基站可以是LTE中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，本发明并不限定。
如图3a或3b所示，本发明实施例中，将原有的1个Normal传输时间间隔(Transmission Time Interval，TTI)(简称：N-TTI，N-TTI＝1ms)划分为2个Shorten TTI(简称：S-TTI，S-TTI＝0.5ms：第一TTI和第二TTI。其中，一子帧(SubFrame，SF)中包含2个时隙(Timeslot)：第N时隙和第N+1时隙。其中，第一TTI对应于第N时隙，第二TTI对应于第N+1时隙。即第一TTI和第二TTI分别为属于同一SF的S-TTI，第一TTI＝0.5ms，第二TTI＝0.5ms。

需要说明的是，本实施例中N为大于等于零的正整数。其中，一个子帧包含2个时隙，即第N时隙和第N+1时隙为同一子帧内的两个时隙。可以对每一个时隙的时隙号ns进行“ns mod 2”运算，这样则可以将每个子帧中的两个时隙分别设置为时隙0和时隙1。示例性的，第N时隙的时隙号ns＝N，第N+1时隙的时隙号ns＝N+1；假设经过“ns mod 2＝N mod 2＝0”运算，可以将第N时隙确定为时隙0，那么经过“ns mod 2＝(N+1)mod 2＝1”运算，可以将第N时隙确定为时隙1。
需要说明的是，本实施例中第N时隙(即第一TTI所对应的时隙)的控制区域即为现有技术的1ms TTT(即N-TTI)的控制区域，1ms TTT的控制区域在频域资源块区域是占有本载波上全部的RB，1ms TTT的控制区域的时域时间单元区域是根据1ms TTT的控制区域中的PCFICH信道指示，可以是1-3个单载波频分多址(Signle-Carrier Frequency Division Multiple Access，SC-FDMA) 符号。
S102、基站在第N+1时隙的控制区域上，向用户设备发送第N+1时隙的物理控制信道，以使得用户设备根据第N+1时隙的物理控制信道确定第N+1时隙的物理数据信道或第N+1+k时隙的物理数据信道，k≥4。

其中，在本发明实施例中，时域控制指示信息用于指示第N+1时隙的控制区域在第N+1时隙中所占用的时域时间单元区域，时域时间单元区域可以为单载波频分多址SC-FDMA符号为单位的时间持续长度，或者占用时间更短的符号为单位的时间持续长度。

相应的，第N+1+k时隙的物理数据信道可以为第N+1+k时隙的PDSCH；或者，第N+1+k时隙的物理数据信道可以为第N+1+k时隙的PUSCH；或者，第N+1+k时隙的物理数据信道可以包括第N+1+k时隙的PDSCH和第N+1+k时隙的PUSCH，k为大于等于4的整数。
其中，如图3a所示，第N+1时隙的PDCCH中可以承载用于指示第N+1+k时隙的PDSCH的控制信息；或者，第N+1时隙的PDCCH中可以承载用于指示第N+1+k时隙的PUSCH的重传指示HARQ信息。如图3b所示，第N+1+k时隙的PHICH可以用于承载用于指示第N+1+k时隙的PUSCH的重传指示HARQ信息。示例性的，如图3a或3b所示，第N+1+k时隙为从第N+1时隙所在的N-TTI的下一个N-TTI开始的第k个S-TTI，k为大于等于4的整数。

本发明一实施例提供一种下行控制信道传输方法，在该下行控制信道传输方法中，如图3a或3b所示，一子帧包括第N时隙和第N+1时隙，第N时隙对应于第一TTI，第N+1时隙对应于第二TTI，如图5所示，该下行控制信道传输方法包括：

S202、用户设备根据第N+1时隙的控制区域指示信息，确定第N+1时隙的控制区域。
其中，由于第N+1时隙的控制区域指示信息包括频域控制指示信息和时域控制指示信息，且频域控制指示信息用于指示第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域，时域控制指示信息用于指示第N+1时隙的控制区域在第N+1时隙中所占用的时域时间单元区域，因此，用户设备可以根据频域控制指示信息和时域控制指示信息的指示，确定第N+1时隙的控制区域。
S203、用户设备在第N+1时隙的控制区域上接收第N+1时隙的物理控制信道，以根据第N+1时隙的物理控制信道确定第N+1时隙的物理数据信道或第N+1+k时隙的物理数据信道，k≥4。
需要说明的是，本实施例中第N时隙的物理控制信道、第N+1时隙的物理控制信道、第N+1时隙的物理数据信道和第N+1+k时隙的物理数据信道(k≥4)的具体内容均可以参考本发明其他实施例中的相关描述，本实施例这里不再赘述。
需要说明的是，本发明实施例中的第N时隙、第N+1时隙以及N的具体描述均可以参考本发明其他实施例中的相关内容，本实施例这里不再赘述。
需要说明的是，本实施例中第N+1时隙的频域资源块区域和时域时间单元区域的具体内容均可以参考本发明其他实施例中的相关描述，本实施例这里不再赘述。

本发明一实施例提供一种下行控制信道传输方法，在该下行控制信道传输方法中，如图3a或3b所示，一子帧包括第N时隙和第N+1时隙，第N时隙对应于第一TTI，第N+1时隙对应于第二TTI，如图6所示，该下行控制信道传输方法包括：

可选的，在本实施例的第一种应用场景中，第N时隙的物理控制信道可以为第N时隙的PDCCH。
在第一种应用场景中，如图7所示，S301可以替换为S301a，S302可以替换为S302a：
S301a、基站通过在第N时隙的控制区域上的第N时隙的PDCCH中承载的下行控制信息DCI，向用户设备发送频域控制指示信息和时域控制指示信息。
其中，频域控制指示信息中包含第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的起始频域资源块位置和第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的长度；其中，频域资源块区域的长度以RB或者RBG为单位。
示例性的，假设频域资源块区域的长度以RB为单位，如图10a 所示，以图10a中频域上的一个单元格为一RB，那么频域控制指示信息则指示第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的起始频域资源块位置则可以为加粗的单元格所代表的RB；第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的长度则可以为6RB(即六个单元格)；第N+1时隙的控制区域在第N+1时隙中所占用的时域时间单元区域则为如图10a所示的时域上3个单元格所代表的3个SC-FDMA符号时域时间。
S302a、用户设备通过第N时隙的控制区域上的第N时隙的PDCCH中承载的(Downlink Control Indicator，DCI)，接收频域控制指示信息和时域控制指示信息。
需要说明的是，在第一种应用场景中，基站可以将频域控制指示信息和时域控制指示信息均通过第N时隙的控制区域上的第N时隙的PDCCH中承载的DCI发送至用户设备。
可选的，在本实施例的第二种应用场景中，第N时隙的物理控制信道可以包括：第N时隙的PDCCH和第N时隙的物理控制格式指示信道(Physical Control Format Indicator Channel，PCFICH)。
在第二种应用场景中，如图8所示，S301可以包括S301b和S301c，S302可以包括S302b和S302c：
S301b、基站通过在第N时隙的控制区域上的第N时隙的PDCCH中承载的DCI，向用户设备发送频域控制指示信息。
S301c、基站通过在第N时隙的控制区域上的第N时隙的PCFICH中承载的控制格式指示CFI，向用户设备发送时域控制指示信息。
其中，第N时隙的PCFICH中承载的CFI包含第N时隙的控制区域在第N时隙中所占用的时域时间单元区域的指示信息，第N+1时隙的控制区域在第N+1时隙中所占用的时域时间单元区域与第N时隙的控制区域在第N时隙中所占用的时域时间单元区域相同。
示例性的，第N时隙的控制区域在第N时隙中所占用的时域时间单元为如图10a所示的时域上3个单元格所代表的SC-FMDA符号 索引0到符号索引2的时域时间，那么，第N+1时隙的控制区域在第N+1时隙中所占用的时域时间单元区域也为如图10a所示的时域上3个单元格所代表的SC-FMDA符号索引0到符号索引2的时域时间。
S302b、用户设备通过第N时隙的控制区域上的第N时隙的PDCCH中承载的DCI，接收频域控制指示信息。
S302c、用户设备通过第N时隙的控制区域上的第N时隙的PCFICH中承载的控制格式指示(Control Format Indicator，CFI)，接收时域控制指示信息。
需要说明的是，在第二种应用场景中，基站可以将频域控制指示信息通过第N时隙的控制区域上的第N时隙的PDCCH中承载的DCI发送至用户设备，将时域控制指示信息通过第N时隙的控制区域上的第N时隙的PCFICH中承载的CFI发送至用户设备。
可选的，在本实施例的第三种应用场景中，第N时隙的物理控制信道可以包括：第N时隙的PDCCH和第N时隙的PCFICH。
在第三种应用场景中，如图9所示，S301可以包括S301b和S301d，S302可以包括S302b和S302d：
S301b、基站通过在第N时隙的控制区域上的第N时隙的PDCCH中承载的DCI，向用户设备发送频域控制指示信息。
S301d、基站通过在第N时隙的控制区域上的第N时隙的PDCCH中承载的DCI和第N时隙的PCFICH中承载的CFI，向用户设备发送时域控制指示信息。
其中，第N时隙的PCFICH中承载的CFI包含第N时隙的控制区域在第N时隙中所占用的时域时间单元区域的指示信息，第N+1时隙的控制区域在第N+1时隙中所占用的参考时域时间单元区域与第N时隙的控制区域在第N时隙中所占用的时域时间单元区域相同。
需要说明的是，假设以图10b所示的时域上的一个单元格作为时域时间单元区域的单位时间，由于第N+1时隙的控制区域在第N+1时隙中所占用的时域时间单元区域可能会在第N时隙的控制区 域在第N时隙中所占用的时域时间单元区域的基础上存在一个或几个单元格的上下波动，即第N+1时隙的控制区域在第N+1时隙中所占用的参考时域时间单元区域与第N时隙的控制区域在第N时隙中所占用的时域时间单元区域相同，第N+1时隙的控制区域在第N+1时隙中所占用的时域时间单元区域可能会在第N+1时隙的控制区域在第N+1时隙中所占用的参考时域时间单元区域存在一个或几个单元格的上下波动，其中，第N+1时隙的控制区域所占用的时域时间单元区域的起始位置均为此第N+1时隙的第一个符号。
例如，如图10b所示，第N时隙的控制区域在第N时隙中所占用的时域时间单元为如图10a所示的时域上3个单元格所代表的SC-FDMA符号索引0到符号索引2的时域时间，即第N+1时隙的控制区域在第N+1时隙中所占用的参考时域时间单元区域为如图10a所示的时域上3个单元格所代表的SC-FDMA符号索引0到符号索引2的时域时间，而第N+1时隙的控制区域在第N+1时隙中所占用的时域时间单元区域则可能会比第N+1时隙的控制区域在第N+1时隙中所占用的参考时域时间单元区域少一个或几个单元格，或者可能会比第N+1时隙的控制区域在第N+1时隙中所占用的参考时域时间单元区域多一个或几个单元格。如图10b所示，第N+1时隙的控制区域在第N+1时隙中所占用的时域时间单元区域比第N+1时隙的控制区域在第N+1时隙中所占用的参考时域时间单元区域少一个单元格，即第N+1时隙的控制区域在第N+1时隙中所占用的时域时间单元区域为如图10b所示的时域上2个单元格所代表的SC-FDMA符号索引0到符号索引1的时域时间。
其中，第N时隙的PDCCH中承载的DCI包含第N+1时隙的控制区域的时间单元区域偏移指示信息，该第N+1时隙的控制区域的时间单元区域偏移指示信息可以为1bit或多个bit的指示信息。以1bit信息为例，当1bit的第N+1时隙的控制区域的时间单元区域偏移指示信息为0时，用于指示第N+1时隙的控制区域在第N+1时隙中所占用的时域时间单元区域比第N+1时隙的控制区域在第N+1 时隙中所占用的参考时域时间单元区域少一个单元格；或者，当1bit的第N+1时隙的控制区域的时间单元区域偏移指示信息为1时，用于指示第N+1时隙的控制区域在第N+1时隙中所占用的时域时间单元区域比第N+1时隙的控制区域在第N+1时隙中所占用的参考时域时间单元区域多一个单元格。
示例性的，以下分别以第N+1时隙的控制区域的时间单元区域偏移指示信息(简称：偏移指示信息)为2bit信息和3bit信息为例，对“第N+1时隙的控制区域在第N+1时隙中所占用的时域时间单元区域”与“第N+1时隙的控制区域在第N+1时隙中所占用的参考时域时间单元区域”之间的关系进行说明。
当偏移指示信息为2bit信息时，偏移指示信息可以为00、01、10、11中的任意一个，以下以列表(表1)的方式给出偏移指示信息分别为00、01、10、11时，所指示的“第N+1时隙的控制区域在第N+1时隙中所占用的时域时间单元区域”与“第N+1时隙的控制区域在第N+1时隙中所占用的参考时域时间单元区域”之间的关系：

当偏移指示信息为3bit信息时，偏移指示信息可以为000、001、010、011、100、101、110、111中的任意一个，以下以列表(表2)的方式给出偏移指示信息分别为000、001、010、011、100、101、110、111时，所指示的“第N+1时隙的控制区域在第N+1时隙中所占用的时域时间单元区域”与“第N+1时隙的控制区域在第N+1时隙中所占用的参考时域时间单元区域”之间的关系：

S302b、用户设备通过第N时隙的控制区域上的第N时隙的PDCCH中承载的DCI，接收频域控制指示信息。
S302d、用户设备通过第N时隙的控制区域上的第N时隙的PDCCH中承载的DCI和第N时隙的PCFICH中承载的CFI，接收时域控制指示信息。
其中，由于第N+1时隙的控制区域在第N+1时隙中所占用的参考时域时间单元区域与第N时隙的控制区域在第N时隙中所占用的时域时间单元区域相同，用户设备在通过第N时隙的PCFICH中承载的CFI接收到第N时隙的控制区域在第N时隙中所占用的时域时间 单元区域的指示信息后，则可以确定第N+1时隙的控制区域在第N+1时隙中所占用的参考时域时间单元区域(如图10b所示的时域上3个单元格所代表的时域时间)；用户设备在通过第N时隙的控制区域上的第N时隙的PDCCH中承载的DCI接收到第N+1时隙的控制区域的时间单元区域偏移指示信息(假设为“0”)；用户设备则可以根据第N+1时隙的控制区域在第N+1时隙中所占用的参考时域时间单元区域和第N+1时隙的控制区域的时间单元区域偏移指示信息确定第N+1时隙的控制区域在第N+1时隙中所占用的时域时间单元区域(如图10b所示的时域上2个单元格所代表的时域时间)。
其中，在上述三种应用场景中，基站均可以采用为用户设备分配的小区无线网络临时标识(Cell-Radio Network Temporary Identifier，C-RNTI)，通过第N时隙的控制区域上的第N时隙的PDCCH中承载的DCI，向用户设备发送频域控制指示信息。
对应的，用户设备则可以采用基站为该用户设备分配的C-RNTI从第N时隙的控制区域上检测基站向该用户设备发送的第N时隙的PDCCH，以获取第N时隙的PDCCH中承载的DCI，并从第N时隙的PDCCH中承载的DCI中获取频域控制指示信息。
优选的，基站可以为多个用户设备分配一个公共Common C-RNTI，并采用该Common C-RNTI，通过第N时隙的PDCCH中承载的(Downlink Control Indicator，DCI)，向用户设备发送频域控制指示信息。
对应的，用户设备则可以采用基站分配的Common C-RNTI从第N时隙的控制区域上检测基站发送的第N时隙的PDCCH，以获取第N时隙的PDCCH中承载的DCI，并从第N时隙的PDCCH中承载的DCI中获取频域控制指示信息。
需要说明的是，如果基站为多个用户设备分配一个公共C-RNTI，那么对于其中一个0.5msTTI的用户设备是来说，可能同时被配置两个C-RNTI，一个是专用的C-RNTI，一个是公共的C-RNTI。其中，用户设备采用专用的C-RNTI检测第N时隙的第一 PDCCH，此第一PDCCH承载用于解调第N时隙的PDSCH的指示信息或者用于指示第N时隙之后的第k个时隙的PUSCH的重传指示HARQ信息；同时，用户设备采用共同的C-RNTI检测第N时隙的第二PDCCH，第二PDCCH中承载实施例中描述的第N+1时隙的控制区域指示信息。

S601、基站向用户设备指示第N+1时隙的S-PCFICH的资源元素位置信息。
示例性的，本发明实施例中，基站可以通过高层信今向用户设备发送第N+1时隙的S-PCFICH的资源元素位置信息。

进一步可选的，在本实施例的第二种应用场景中，第N+1时隙的S-PCFICH中承载有频域资源长度信息和时域控制指示信息。其中，频域资源长度信息用于指示第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的长度。
S603、基站在第N+1时隙的控制区域上，向用户设备发送第N+1时隙的物理控制信道。
S604、用户设备确定第N+1时隙的S-PCFICH的资源元素位置信息。
示例性的，本发明实施例中，用户设备可以通过高层信今或预定义的，确定第N+1时隙的S-PCFICH的资源元素位置信息。
其中，当用户设备通过预定义方式确定第N+1时隙的S-PCFICH的资源元素位置信息，即用户设备中预先定义有第N+1时隙的S-PCFICH的资源元素位置信息时，则可以不执行S601，即基站可以直接在第N+1时隙的S-PCFICH的资源元素位置信息所指示的资源元素位置上，向用户设备发送第N+1时隙的S-PCFICH(即直接执行S602)。
S605、用户设备在第N+1时隙的S-PCFICH的资源元素位置信息所指示的资源元素位置上，接收第N+1时隙的S-PCFICH信道。
S606、用户设备根据第N+1时隙的S-PCFICH的资源元素位置信息和第N+1时隙的S-PCFICH，确定第N+1时隙的控制区域指示信息。
其中，控制区域指示信息包括频域控制指示信息和时域控制指示信息，频域控制指示信息用于指示第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域，时域控制指示信息用于指示第N+1时隙的控制区域在第N+1时隙中所占用的时域时间单元区域。
示例性的，频域控制指示信息中可以包含第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的起始频域资源块位置和第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的长度；其中，频域资源块区域的长度以RB或者RBG为单位。
在本实施例的第一种应用场景中，第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的起始频域资源块位置与第N+1时隙的S-PCFICH在第N+1时隙中所占用的频域资源块区域的起始频域资源块位置相同；第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的长度等于第N+1时隙的S-PCFICH所在第N+1时隙中的频域资源块区域的长度+L，L为大于等于0的整数；第N+1时隙的S-PCFICH中承载有时域控制指示信息。如图14所示，在第一种应用场景中，S606可以包括S606a和S606b：
S606a、用户设备根据第N+1时隙的S-PCFICH的资源元素位置信息，确定频域控制指示信息。
具体的，用户设备可以根据资源元素位置信息中包含的第N+1时隙的S-PCFICH在第N+1时隙中所占用的频域资源块区域的起始频域资源块位置，确定第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的起始频域资源块位置；其中，第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的起始频域资源块位置与第N+1时隙的S-PCFICH在第N+1时隙中所占用的频域资源块区域的起始频域资源块位置相同。
示例性的，假设频域资源块区域的长度以RB为单位，如图16所示，以图16中频域上的一个单元格为一RB为例。若频域控制指示信息指示第N+1时隙的S-PCFICH在第N+1时隙中所占用的频域资源块区域的起始频域资源块位置为加粗的单元格所代表的RB，由于第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的起始频域资源块位置与第N+1时隙的S-PCFICH在第N+1时隙中所占用的频域资源块区域的起始频域资源块位置相同，因此，第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的起始频域 资源块位置也即为加粗的单元格所代表的RB。
用户设备可以根据第N+1时隙的S-PCFICH所在第N+1时隙中的频域资源块区域的长度，确定第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的长度；其中，第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的长度等于第N+1时隙的S-PCFICH所在第N+1时隙中的频域资源块区域的长度+L，L为大于等于0的整数。
示例性的，如图16所示，可知第N+1时隙的S-PCFICH所在第N+1时隙中的频域资源块区域的长度为5RB(五个单元格所代表的频域资源块区域的长度，即图16中加粗圆圈所标示的频域资源块区域)。由于第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的长度等于第N+1时隙的S-PCFICH所在第N+1时隙中的频域资源块区域的长度+L，L≥0；因此，第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的长度则至少可以为5RB(即六个单元格所代表的频域资源块区域的长度)。
S606b、用户设备根据根据第N+1时隙的S-PCFICH中承载的辅控制格式指示信息(Secondary-Control Format Indicator，S-CFI)，确定时域控制指示信息。
其中，第N+1时隙的S-PCFICH中承载的S-CFI中可以包含用于指示第N+1时隙的控制区域在第N+1时隙中所占用的时域时间单元区域的时域控制指示信息。
在本实施例的第二种应用场景中，第N+1时隙的控制区域在所述第N+1时隙中所占用的频域资源块区域的起始频域资源块位置与第N+1时隙的S-PCFICH在第N+1时隙中所占用的频域资源块区域的起始频域资源块位置相同；但是，与本实施例的第一种应用场景中不同的是，基站是通过第N+1时隙的S-PCFICH中承载的频域资源长度信息向用户设备指示第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的长度的。在第二种应用场景中，如图15所示，S606可以包括S606c：
S606c、用户设备根据第N+1时隙的S-PCFICH的资源元素位置信息，确定第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的起始频域资源块位置。
其中，第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的起始频域资源块位置与第N+1时隙的S-PCFICH在第N+1时隙中所占用的频域资源块区域的起始频域资源块位置相同。
S606d、用户设备根据第N+1时隙的S-PCFICH中承载的S-CFI，确定第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的长度和时域控制指示信息。
其中，第N+1时隙的S-PCFICH中承载的S-CFI中可以包含时域控制指示信息和第N+1时隙的控制区域在第N+1时隙中所占用的频域资源块区域的长度的指示信息。
S607、用户设备根据第N+1时隙的控制区域指示信息，确定第N+1时隙的控制区域。
S608、用户设备在第N+1时隙的控制区域上接收第N+1时隙的物理控制信道，以根据第N+1时隙的物理控制信道确定第N+1时隙的物理数据信道或第N+1+k时隙的物理数据信道，k≥4。

并且，在本方案中第N时隙(第一TTI对应的时隙，即S-TTI-0对应的时隙)的控制区域即为N-TTI的控制区域，即第一TTI仍复用N-TTI的控制区域，即本方案中基站可以采用N-TTI的控制区域向用户设备指示第N+1时隙(第二TTI对应的时隙，即S-TTI-1所对应的时隙)的控制区域，即通过本方案可以实现1ms N-TTT与0.5ms S-TTI的兼容，可以避免第N+1时隙的控制区域的传输对1ms N-TTT的物理数据信道的传输的影响。
