Definitions

  • the present invention relates to the field of communications technologies, and in particular, to a data transmission method, apparatus, and system.
  • the control channel is transmitted using cell-specific resources.
  • the base station transmits a control channel on the bandwidth of the entire 4G LTE system, and the user equipment (User Equipment, UE) performs blind detection on all possible resources in the entire system bandwidth, and the receiving base station sends the control channel. It controls signaling to complete the receipt of subsequent information.
  • the transmission resources of the control channel of the 5G NR system are still transmitted in the same system bandwidth as the 4G LTE system. On the one hand, it will cause waste of frequency resources; because the capacity of the control channel is small compared to the data; on the other hand, the cost of the UE will rise sharply because the bandwidth of the 5G NR defined above is the work of the base station.
  • Bandwidth since the base station serves multiple UEs at the same time, the working bandwidth of each UE is much smaller than the working bandwidth of the above base station.
  • each subframe of the 4G LTE can be divided into a control region and a data region, where the control region is located at the beginning of the subframe, and the control region of each subframe occupies an integer number of OFDM symbols, and the OFDM number can be Dynamically adjusted to meet real-time traffic requirements.
  • the base station Before transmitting the downlink control signaling, the base station determines how many OFDM symbols are occupied by the control region according to the traffic situation, and then transmits a Physical Format Format Indicator Channel (PCFICH) by using the fixed-location resource, and the PCFICH is used to indicate The number of OFDM symbols occupied by the control region.
  • PCFICH Physical Format Format Indicator Channel
  • the UE receives the PCFICH before receiving the downlink control signaling, and obtains the range of the control region.
  • Disadvantage 1 The resources used for control channel transmission will occupy the entire bandwidth in the frequency domain, so multiplexing is only performed in time. That is to say, PCFICH can only implement multiplexing of control resources in the time domain, and control resources in the frequency domain cannot be used for data transmission. For example, when there are few UEs to be scheduled in the 4G LTE network, only a small amount of resources are needed for the transmission of the downlink control signaling, and the base station informs the UE through the PCFICH that the current downlink control signaling occupies 1 OFDM symbol.
  • the control signaling is mapped to a resource element (RE) within the system bandwidth according to a certain rule, and the resource unit occupies one in the frequency domain.
  • Subcarriers occupy one OFDM symbol in the time domain.
  • other REs within the system bandwidth of the OFDM symbol can only be vacant and cannot be reused for data transmission.
  • the second disadvantage is that the PCFICH is the information defined by the cell, and the UE in the cell needs to receive the PCFICH correctly before receiving the downlink control signaling. Because, in the 5G NR system, the working bandwidth of different UEs is different within the entire system bandwidth of the base station.
  • the working frequency band of 5G NR includes high frequency band.
  • the path loss of high frequency signal will be very large in the process of high frequency band propagation.
  • wireless communication systems operating in high frequency band will often pass through the beam. Forming, the energy of the wireless signal is concentrated to a small angle range, thereby resisting serious path loss by obtaining a large power gain.
  • the beamforming can only cover a small range.
  • the PCFICH carried on the beam is the same, which means that the PCFICH is copied and sent multiple times, resulting in excessive signaling overhead. . Therefore, reducing the signaling overhead and implementing the idle resources in the control resource set can be dynamically used for data transmission is urgently needed.

Description

数据传输方法、装置及系统
本申请要求于2017年02月11日提交中国专利局、申请号为201710074546.5、申请名称为“数据传输方法、装置及系统的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及一种通信技术领域，尤其涉及一种数据传输方法、装置及系统。
背景技术
在4G LTE系统中，控制信道是利用小区特定的资源来发射的。例如，在频域中，基站会在整个4G LTE系统的带宽上发射控制信道，用户设备(User Equipment，UE)会在整个系统带宽范围内的所有可能的资源上进行盲检测，接收基站发给它的控制信令，以完成后续信息的接收。而5G NR系统的控制信道的发射资源仍与4G LTE系统的一样，在整个系统带宽上来发射。一方面，会造成频率资源的浪费；因为，控制信道的容量相比数据，是很小的；另一方面，会造成UE的成本急剧上升，因为，上述定义的5G NR的带宽是基站端的工作带宽，由于基站同时服务多个UE，因此每个UE的工作带宽远小于上述基站的工作带宽。
而现有技术的4G LTE系统中，4G LTE的每个子帧都可以分为控制区域和数据区域，其中控制区域位于子帧的开头，每个子帧的控制区域占用整数个OFDM符号，OFDM数量可以动态调整以适应实时通信量的要求。基站在发射下行控制信令前，会根据业务量情况确定控制区域占用多少个OFDM符号，然后用固定位置的资源发射一个物理格式指示信道信道(Physical Control Format Indicator Channel，PCFICH)，PCFICH用于指示控制区域所占用的OFDM符号个数。UE在接收下行控制信令前，先接收PCFICH，获得控制区域的范围。
上述方案有三个缺点。缺点一，用于控制信道发射的资源在频域上会占满整个带宽，因此复用只在时间上进行。也就是说PCFICH只能实现时域上的控制资源的复用，频域上控制资源无法用于数据传输。例如，当4G LTE网络中需要调度的UE很少时，这时只需要很少的资源用于下行控制信令的发射，基站通过PCFICH告知UE当前的下行控制信令会占用1个OFDM符号。在包括下行控制信令的时隙的第1个OFDM符号上，根据一定的规则在系统带宽内，将控制信令映射到资源单元(Resource element，RE)，该资源单元在频域上占用一个子载波，时域上占一个OFDM符号。系统带宽上除了用于发射下行控制信令的RE外，OFDM符号上的系统带宽范围内的其他RE只能空置，不能被复用于数据的发射。缺点二，PCFICH是小区定义的信息，小区内的UE需要在正确接收到PCFICH才能进行下行控制信令的接收。因为，在5G NR系统中，不同UE的工作带宽在基站整个系统带宽范围内是不同的，若为了保证每个UE都能接收到PCFICH信道，需要预先确定一个固定的资源用于发射PCFICH。但是， 两者在频率上很可能是不连续的，这就会使UE实现复杂度提高，从而增加UE的成本。缺点三，5G NR的工作频段包括高频频段，高频信号在高频频段传播的过程中路损会很大，为了抵抗严重的传播路损，工作于高频频段的无线通信系统往往会通过波束赋形，将无线信号的能量集中到很小的角度范围内，进而通过获得较大的功率增益抵抗严重的路损。波束赋形只能覆盖一个很小的范围，为了保证小区所有的UE能够接收到PCFICH，需要波束上承载的PCFICH是相同，也就是意味着PCFICH被复制发送多份，从而造成信令开销过大。因此，减少信令开销，实现控制资源集合中的空闲资源能够动态的用于数据传输是迫切需要实现的。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行描述。
在本发明实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本发明。在本发明实施例和所附权利要求书中所使用的单数形式的“一种”，“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。还应当理解的是，本文中的“第一”、“第二”也旨在叙述时对技术名词作区分，便于读者理解，不应理解对技术名词的限定。
下面首先结合图1对本发明实施例可能适用的系统架构进行介绍。图1为本发明实施例提供的一种可能的通信系统架构示意图。如图1所示，该通信系统架构包括：发送装置110、接收装置120以及接收装置130。在一个实施例中，发送装置或接收装置的数量可以不止一个，图1仅示出一个为例来进行说明。
在一个实施例中，发送装置110向接收装置120和接收装置130发送第一组控制资源集合；发送装置110向接收装置120和接收装置130发送第一信令，第一信令用于指示接收装置120和接收装置130在传输数据的时频资源上接收数据。
发送装置110、与接收装置120、与接收装置130之间的通信方式，例如，可以为无线电波，也可以通过可见光、激光、红光、光纤等通信方式。在本发明实施例中，发送装置可以包括，但不限于基站、无线接入点、用户装置；接收装置可以包括，但不限于用户装置、终端、移动台(Mobile station，MS)、UE或基站。
本申请中名词“网络”和“系统”经常交替使用，但本领域的技术人员可以理解其含义。本申请所涉及到的用户设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备(wearable device，WD)、计算设备或连接到无线调制解调器的其它处理设备,以及各种形式的移动台，终端(terminal)，终端设备(terminal equipment)等等。

本申请涉及的通信系统中，发送装置根据第一信令，动态的触发第二组控制资源 集合复用于数据发送，在不增加太多信令开销的前提下，提高无线资源的利用效率。
相应地，图2为本发明实施例提供的一种数据传输方法的通信示意图。如图2所示，该实施例包括步骤S201-步骤S204：
步骤201：发送装置向接收装置发送第一组控制资源集合。
在一个实施例中，发送装置向接收装置发送第一组控制资源集合和第二组控制资源集合。
在一个实施例中，发送装置向接收装置分开发送第一组控制资源集合和第二组控制资源集合。
具体地，发送装置将第一组控制资源集合和第二组控制资源集合分别通过不同的下行信令通知接收设备。
例如，发送装置为每个连接到其之上的接收装置预先配置第一组控制资源集合{C i,1≤i≤N}，通过下行信令通知给接收装置，其中，下标i表示接收装置的编号，N表示接收装置的个数。发送装置再将第二组控制资源集合R i通过另一条下行信令通知接收装置配置。
在一个实施例中，发送装置向接收装置同时发送第一组控制住资源集合和第二组控制资源集合。
具体地，发送装置将第一组控制资源集合和第二组控制资源集合通过同一条下行信令通知接收装置。
例如，当配置第一组控制资源集合C i的周期和配置第二组控制资源集合R i的周期相同时，可以同时配置第一控制资源集合C i的周期第二组控制资源集合R i，即在一条下行信令同时包括第一控制资源集合C i的周期第二组控制资源集合R i；也可以通过不同的下行信令通知接收装置。
在一个实施例中，发送装置采用半静态的方式，向接收装置发送第一组控制资源集合。
可选的，发送装置向接收装置发送第一组控制资源集合C i。假设，相邻的两个控制资源集合C i和C i+1，发送装置向接收装置发送C i和C i+1之间的时间间隔可以根据发送装置的调度情况确定，例如，时间间隔为几十、甚至几百毫秒。
在一个实施例中，发送装置采样半静态的方式，向接收装置发送第二组控制资源集合。
可选的，发送装置向接收装置发送第二组控制资源集合R i。假设，相邻的两个控制资源集合R i和R i+1，同样的，发送装置向接收装置发送R i和R i+1之间的时间间隔可以根据发送装置的调度情况确定。在此不赘述。
在一个实施例中，发送装置采用半静态的方式，向接收装置发送第一组控制资源集合和第二组控制集合。
可选的，发送装置分别向接收装置发送第一组控制资源集合C i和第二组控制资源集合R i，也就是不同时向接收装置发送第一组控制资源集合C i和第二组控制资源集合R i。假设，相邻的两个控制资源集合C i和C i+1，相邻的两个控制资源集合R i和R i+1，发送装置向接收装置发送C i和C i+1之间的时间间隔可以根据发送装置的调度情况确定，例如，时间间隔为几十、甚至几百毫秒。同样的，发送装置向接收装置发送R i和R i+1之 间的时间间隔可以根据发送装置的调度情况确定。在此不赘述。
需要说明的是，发送装置采用半静态的方式向接收装置发送第一组控制资源集合和第二组控制资源集合，与实时动态发送第一组控制资源集合和第二组控制资源集合相比，降低信令开销。
可选的，在半静态的发送方式下，发送装置为每个接收装置配置的控制资源集合相互之间的关系包括以下几种：
第一种，控制资源集合相互之间是独立的，相互不重叠(如图3)。例如，控制资源集合C i和C j相互之间是独立的，相互不重叠，及
Figure PCTCN2018075903-appb-000001
第二种，控制资源集合相互之间存在重叠，但是不完全重合(如图4)。
第三种，控制资源集合相互之间安全重合(如图5)。
在一个实施例中，第二组控制资源集合R i为第一组控制资源集合C i的子集；或者，第二组控制资源集合R i为第一组控制资源集合C i的补集的子集，即
Figure PCTCN2018075903-appb-000002
Figure PCTCN2018075903-appb-000003
表示C i的补集。
具体地，发送装置接收装置配置第二组控制资源集合R i，第二组控制资源集合R i是第一组控制资源集合
Figure PCTCN2018075903-appb-000004
的补集的一个子集
Figure PCTCN2018075903-appb-000005
其中，
Figure PCTCN2018075903-appb-000006
为C i的补集，
Figure PCTCN2018075903-appb-000007
表示在控制区域内，除了C i之外的控制资源集合，第二控制资源集合R i对应的时频资源与第一组控制资源集合C i对应的资源不重叠。
可选的，第一组控制资源集合{C i,1≤i≤N}在频域中是接收装置工作的系统带宽范围内连续或不连续的资源块，在时域中处于每个子帧的前1个或2个OFDM符号上。
需要说明的是，本发明实施例中的下行信令是高层配发指令。
步骤202：接收装置接收发送装置发送的第一组控制资源集合，第一组控制资源集合指示控制资源集合位置。
在一个实施例中，接收装置接收发送装置发送的第一组控制资源集合和第二组控制资源集合，第一组控制资源集合指示控制资源集合位置，第二组控制资源集合用于指示发送装置是否在第二组控制资源集合上发送数据，其中，第二组控制资源集合为第一组控制资源集合的子集；或者，第二组控制资源集合为第一组控制资源集合的补集的子集。
在一个实施例中，接收装置分别接收第一组控制资源集合和第二组控制资源集合。
具体地，接收装置接收两条下行信令，分别获得第一组控制资源集合和第二组控制资源集合。
在一个实施例中，接收装置接收一条信令，获得第一组控制资源集合和第二组控制资源集合。
在一个实施例中，接收装置采用半静态的方式，接收发送装置发送的第一组控制资源集合和第二组控制资源集合。
具体地，由于发送装置采用半静态的方式发送第一组控制资源集合和第二组控制资源集合，那么接收装置在接收的时候也会是半静态的方式进行接收。假设，接收装置在t0时刻，接收装置接收控制资源集合C i，在t1时刻，接收装置接收控制资源集 合C i+1，那么在t0和t1之间的通信过程中，由于t1时刻还没到来，接收装置还没有接收控制资源集合C i+1，接收装置将接收的控制资源集合C i作为自己的控制资源集合。
在一个实施例中，第二组控制资源集合R i为第一组控制资源集合C i的子集；或者，第二组控制资源集合R i为第一组控制资源集合C i的补集的子集，即
Figure PCTCN2018075903-appb-000008
Figure PCTCN2018075903-appb-000009
表示C i的补集。
具体地，发送装置接收装置配置第二组控制资源集合R i，第二组控制资源集合R i是第一组控制资源集合
Figure PCTCN2018075903-appb-000010
的补集的一个子集
Figure PCTCN2018075903-appb-000011
其中，
Figure PCTCN2018075903-appb-000012
为C i的补集，
Figure PCTCN2018075903-appb-000013
表示在控制区域内，除了C i之外的控制资源集合，第二控制资源集合R i对应的时频资源与第一组控制资源集合C i对应的资源不重叠。
可选的，第一组控制资源集合{C i,1≤i≤N}在频域中是接收装置工作的系统带宽范围内连续或不连续的资源块，在时域中处于每个子帧的前1个或2个OFDM符号上。
需要说明的是，接收装置采用半静态的方式接收第一组控制资源集合和第二组控制资源集合，与实时动态接收第一组控制资源集合和第二组控制资源集合相比，降低了信令开销。
步骤203：发送装置向接收装置发送第一信令，第一信令用于指示接收装置在传输数据的时频资源上接收数据。
在一个实施例中，发送装置向接收装置发送第二信令，第二信令用于指示接收装置在传输数据的时频资源和接收装置在第二组控制资源集合对应的时频资源上接收数据。
在一个实施例中，第二信令包括第一指令和第二指令，第一信令包括第一指令。第一指令用于指示传输数据的时频资源，第二指令用于指示是否复用第二组控制资源集合对应的时频资源用于数据传输。
具体地，发送装置完成调度后，例如，根据控制信道容量，也可以根据控制信道状况，确定是否将第二组控制资源集合用于数据传输，通知接收装置第二组控制资源集合是否用于数据传输的方法包括以下几种：
第一种方式：发送装置在确定第二组控制资源集合对应的时频资源不用于传输数据时，发送装置将发送给接收装置的第一信令在第一组控制资源集合和第二组控制资源集合上映射，且第二指令设置为第二控制资源集合对应的时频资源不用于数据传输。
例如，第二组控制资源集合R i对应的时频资源全部不用于数据传输时，则将第一信令在第一组控制资源集合C i对应的时频资源和第二组控制资源集合R i对应的时频资源上直接进行映射，并且将第二指令设置为“否”。
第二种方式：发送装置在确定第二组控制资源集合对应的时频资源全部用于传输数据时，发送装置将发送给接收装置的第一信令在第一组控制资源集合上映射，且第二指令设置为第二控制资源集合对应的时频资源用于数据传输，同时将数据而不是第一指令在第二组控制资源集合上映射。
例如，第二组控制资源集合R i对应的时频资源全部用于数据传输时，则将第一信令在第一组控制资源集合C i对应的时频资源上映射，并且将第二指令设置为“是”，同时在第二组控制资源集合R i对应的时频资源上不映射第一信令，而是将数据映射到第二控制资源集合R i对应的时频资源上。
第三种方式：发送装置在确定第二组控制资源集合对应的时频资源中的一段视频或几段用于传输数据时，发送装置在第一信令中添加用于指示数据区域起始位置的指示信令。
可选的，第一信令包括第三指令。第三指令用于指示数据区域的起始位置。
具体地，发送装置确定第二组控制资源集合R i对应的时频资源用于数据传输。发送装置将第一信令中增加用于指示数据区域起始位置的第三指令。
可选的，第一信令包括用于指示数据发送的资源指示，以及是否复用第二组控制资源集合的时频资源用于数据传输的触发指示。
可选的，触发指示可以只需要1～2比特物理层信令就可以完成控制第二组控制资源集合复用数据传输。与现有技术通过PCFICH传播物理层信令相比，降低了信令开销。
需要说明的是，本发明实施例中的第一信令是指下行控制信令，采用“第一”旨在叙述时对技术名词作区分。下文描述的时候，统称为下行控制信令。
步骤204：接收装置接收发送装置发送的第一信令，根据第一信令在传输数据的时频资源。
在一个实施例中，接收装置接收发送装置发送的第一信令，根据第一信令在传输数据的时频资源和第二组控制资源集合对应的时频资源上接收数据。
在一个实施例中，接收装置在接收到发送装置发送的下行信令时，接收装置在第一组控制资源集合对应的时频资源上，进行盲扫描。
具体地，接收装置在第一组控制资源集合对应的时频资源的任一段时频资源上进行信息解码，例如，通过调制和编码方式进行信息解码，将解码的信息与校验码进行比较，当解码的信息与校验码相同时，则解码的信息为发送装置发送给接收装置的下行控制信令；当解码的信息与校验码不同时，则在一下段时频资源以相同的方式继续进行盲检测。其中，校验码可以通过预设的方式在接收装置和发送装置生成。校验码的生成方式是常规操作，在此不做赘述。
在一个实施例中，第一信令包括第一指令和第二指令；第一指令用于指示传输数据的时频资源，第二指令用于指示是否复用第二组控制资源集合对应的时频资源用于数据传输。
具体地，当第二指令为第二组控制资源集合用于数据传输时，在传输数据的时频资源和第二组控制资源集合对应的时频资源上接收数据；或者，
当第二指令为第二组控制资源集合不用于数据传输时，在传输数据的时频资源上接收数据。
例如，当接收装置正确接收到来自发送装置的第一信令，并且其中触发第二组资源子集
Figure PCTCN2018075903-appb-000014
用于数据传输的第二指令为“是”时，则在第一指令指示的数据传输资源的频率位置对应的时频资源以及第二组控制资源集合R i对应的时频资源上接收数据；当触发第二组控制资源集合R i用于数据传输的第二指令为“否”时，则只在第一指令指示的数据传输资源的频率位置对应的时频资源上接收数据。
需要说明的是，第一指令为1～2个比特物理层信令，就可以完成第二组控制资源 集合R i复用于数据传输。
在一个实施例中，第一信令包括第三指令，第三指令用于指示数据区域的起始位置。
具体地，接收设置根据携带有第三指令的第一信令，与下行控制信令中的资源分配所指示的资源比较，自适应的确定每个频率资源内所对应的用于数据传输的资源。
接收装置可以通过以下方式之一自适应的确定每个频率资源内的用于数据传输的资源：
第一种方式：当数据资源在频域上与第二组控制资源集合R i在频域重合时，数据区域的起始位置则根据第一信令中指示的数据区域起始位置的第三指令确定；当数据资源在频域上与第二组控制资源集合R i在频域不重合时，数据区域的起始位置则是预先设定的位置。
以附图6为例，假设，控制资源集合C 1占用时隙的前2个OFDM符合，而UE1的控制资源集合R 1在第2个OFDM符合上，当R 1对应的时频资源复用于传输数据时，基站通过第一信令通知UE1：数据传输是从第2个OFDM符号开始，那么在区域a的频率资源，由于与R 1对应的时频资源不重合，那么这个频率范围内的数据传输从第3个OFDM符号开始；而对于区域b，区域b对应的频率资源与R 1对应的时频资源是对应的，数据传输是从第2个OFDM符号开始。
而对于UE2，由于没有收到第三指令，即使UE2分配的数据资源在频率上与R 2对应的时频资源是重合的，但是，R 2对应的时频资源不会被复用于数据传输，其数据传输的起始位置仍然从第3个OFDM符合开始。
第二种方式：当数据资源在频域上与第二组控制资源集合R i在频域重合时，数据区域的起始位置则是从预先设定的位置。当数据资源在频域上与第二组控制资源集合R i在频域不重合时，数据区域的起始位置则根据第一信令中指示的数据区域起始位置确定。
以附图7为例，假设，只复用控制区域内、第一组控制资源集合C 1外的控制资源对应的时频资源，基站通过下行控制信令通知UE1：数据传输的起始位置为第1个OFDM符号，在UE1接收下行控制信令后，UE1在区域a、b、c三个区域内的资源上接收数据。
以图8为例，假设，基站同时复用控制区域内、第一组控制资源集合C 1内外的控制资源对应的时频资源，基站通过下行控制信令通知UE1，数据传输从第2个OFDM符号开始。假设，基站给UE1配置了两段时频资源用于数据传输，其中a段对应的频率与控制资源集合R 1在频域上部分重叠，b段对应的频率与控制资源集合C 1完全重合，UE1在接收到下行控制信令后，根据数据传输起始位置，以及用于数据传输的指示的时频资源和控制资源集合R 1的位置，确定每一个数据资源在时间上的起始位置。假设，在区域a、b、c、d对应的时频资源上用于数据接收。
以图9为例，假设，只复用控制区域内、第一组控制资源集合C 1外的控制资源对应的时频资源，基站通过下行控制信令通知UE1，当第二指令为“是”，UE1在第一组控制资源集合中、以及第三指令指示的数据区域的起始位置对应的时频资源上映射数据。
或者，第一信令中只包括第三指令，UE1在在控制区域内、第一组控制资源集合以外的时频资源、以第三指令指示的起始位置开始的时频资源上接收数据。
以图10为例，假设，基站同时复用控制区域内、第一组控制资源集合C 1内外的控制资源对应的时频资源。基站通过下行控制信令通知UE1，当第一信令只包括第三指令时，UE1在控制区域内、第一组控制资源集合内外的时频资源、以第三指令指示的起始位置开始的时频资源上接收数据。但，在第一控制集合所对应的时频资源用于发送第一信令的时频资源上，基站不映射数据。
在本申请的实施例中，通过上述示例，本发明实施例提供的数据传输中，通过在下行控制信令中指示的数据传输资源的频率位置对应的时频资源、以及第二组控制资源集合对应的时频资源上接收数据。降低信令开销，同时在控制资源集合中实现控制信道与数据动态复用。
图2所示的数据传输方法具体可参见下述实施例一、实施例二提供的两个具体的实施例。
实施例一
本发明实施例一中的系统提供一种通信系统，该通信系统包括基站和UE1和UE2。该系统用于复用第一组控制资源集合C i内的空闲用于数据发送。第二组控制资源子集R i是第一组控制资源集合C i的子集。
具体地，如图3所示，基站分别为UE1配置控制资源集合C 1和控制资源子集R 1，以及UE2配置控制资源集合C 2和控制资源子集R 2。控制资源集合C 1和控制资源集合C 2处于子帧开头的控制区域内。在控制资源集合C 1和C 2对应的时频资源被用于承载UE1和UE2的下行控制指令的下行控制信道的传输，下行控制信令包括用于数据传输的资源指示、以及是否复用控制资源子集R 1和控制资源子集R 2中的时频资源用于数据传输的触发指示。由于，UE1的控制信道容量相对于控制资源集合C 1占比不大，因此，控制资源子集R 1被用于UE1的数据传输；而UE2的控制信道的容量相对于控制资源集合C 2占比较大，因此，控制资源子集R 2没有被触发用于数据传输。接下来基站通过向UE1发送下行控制信令通知控制资源子集R 1被用于UE1的数据传输，基站通过向UE2发送下行控制信令通知控制资源子集R 2不被用于UE1的数据传输。
在一个实施例中，C 1和C 2对应的时频资源中的一段资源或多段资源用于承载UE1和UE2的下行控制信令的下行控制信道PCFICH的传输，PCFICH对应指示C 1和C 2占用的OFDM符号的个数；其中，下行控制信令包括用于数据传输的资源指示，以及是否复用R 1和R 2对应的时频资源用于数据传输的触发指示。
实施例二
本发明实施例一中的系统提供一种通信系统，该通信系统包括基站和UE1和UE2。该系统用于复用控制区域内，第一组控制资源集合C i内外的空闲用于数据发送。第二组控制资源子集R i是第一组控制资源集合C i的补集的子集。
假设，控制区域包括前面的2个OFDM符号，UE1的控制资源子集也包含前面的2个OFDM符号。
在一个实施例中，通知UE，第二组控制资源集合R i对应的时频资源是否用于数据传输可以采用以下方式：
第一种方式：即在物理层信令中添加指示位来指示第二组控制资源集合R i对应的时频资源是否用于数据传输。
第二种方式：通过在物理层信令中添加数据区域开始符号的指示信令，来指示数据区域起始的符号位置。
当第二组控制资源子集R i复用用于数据传输时，对于数据的处理可以采用两种不同方式：
第一种方式：只复用控制区域内、控制资源集合外的资源，如图6所示，基站通过下行控制信令通知UE1：数据传输从第1个OFDM符号开始，那么UE1接收到下行控制信令后，在a、b、c三个区域内的资源上接收数据。
第二种方式：同时复用控制区域内、控制资源集合内外的资源，如图8所示，基站通过下行控制信令通知UE1：数据传输从第2个OFDM符号开始，假设在频域上，基站共为UE1分配了两段资源用于数据传输，其中上方一段频率资源与控制资源子集R 1在频域上部分重叠，而下方一段频率资源与控制资源集合在频域上完全重叠，那么UE1接收到下行控制信令后，根据数据传输起始位置，以及资源在频域上的位置与控制资源子集R 1的位置，确定每一个数据资源在时间上的起始位置，即假设在a、b、c、d四个区域内的资源用于数据接收。
