Description

资源映射方法、网络设备和终端设备
本申请要求于2017年05月04日提交中国专利局、申请号为201710309848.6、申请名称为“资源映射方法、网络设备和终端设备”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
本申请涉及通信技术，尤其涉及一种资源映射方法、网络设备和终端设备。
背景技术
在第五代通信******的新空口(New Radio，NR)标准中，下行传输资源被分为控制区域和数据区域。其中，控制区域用于传输控制信道，数据区域用于传输数据信道。控制信道承载的下行控制信息用于指示数据信道所使用的资源块(Resource Block，RB)在数据区域的频域位置，数据信道用于承载下行数据。
在NR标准中，控制信道可以使用一个或多个控制信道元素(Control Channel Elements，CCE)进行传输。其中，一个CCE由多个资源元素组(Resource Element Group，REG)组成。因此，基站发送控制信道时，需要在下行传输资源的控制区域内，对控制信道进行CCE到REG的资源映射。即，以REG为CCE的基本单位，把控制信道所使用的每个CCE映射到下行传输资源上。在使用这种方式进行资源映射时，下行传输资源的控制区域内未被控制信道占用的资源，即为控制区域内的空闲资源。
目前，NR标准中提出，当控制区域内存在空闲资源时，数据信道可以复用空闲资源进行数据传输，以提高资源利用率。因此，当数据信道使用控制区域的资源时，基站如何为数据信道进行资源分配，提高控制区域的资源的使用效率，是一个亟待解决的问题。

以5G通信***为例，5G通信***的NR标准中，下行传输资源在频域上为下行***带宽
Figure PCTCN2018084336-appb-000001
，在时域上由若干个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号(例如：7个或14个OFDM符号)组成。
图2为一种下行***带宽的示意图。如图2所示，
Figure PCTCN2018084336-appb-000002
的基本单位为资源块(Resource Block，RB)。其中，每个RB在频域上由12个连续的子载波组成，在时域上由6或7个OFDM符号组成。继续参照图2，在图2所示的RB的资源网格上的每个网格称为一个资源元素(Resource Element，RE)，每个RE包含一个OFDM符号内的一个子载波。
图3为一种下行传输资源的示意图。如图3所示，在本申请中，下行传输资源在时域上被分为控制区域和数据区域。也就是说，控制区域和数据区域在频域(frequency domain)上均由整个下行***带宽
Figure PCTCN2018084336-appb-000003
组成，但在时域(time domain)上由不同的时域符号组成。需要说明的是，后续所有附图中，时域均用time表示，频域均用frequency表示，不再一一解释。
其中，控制区域用于传输控制信道，数据区域用于传输数据信道。控制信道承载的控制信息能够指示数据信道所使用的RB在数据区域的频域位置(即数据信道的资源分配信息)，数据信道用于承载下行数据或上行数据。其中，这里所说的控制信道例如可以为物理下行控制信道(Physical Downlink Control Channel，PDCCH)，控制信道承载的控制信息例如可以为下行控制信息(Downlink Control Information，DCI)。这里所说的数据信道例如可以为物理下行共享信道(Physical Downlink Shared Channel，PDSCH)。
为了提高终端设备盲检控制信道的效率，NR标准提出了控制资源集合(control resource set)的概念。即，在控制区域为每个终端设备划分一个或多个控制资源集合。网络设备可以在终端设备对应的任一控制资源集合上，向终端设备发送控制信道。图3示出的是在控制区域上为终端设备划分了2个控制资源集合：控制资源集合1(control resource set1)和控制资源集合2(control resource set2)的下行传输资源。如图3所示，网络设备可以在控制资源集合1上，向终端设备发送控制信道，也可以在控制资源集合2上，向终端设备发送控制信道。
需要明确的是，发送控制信道可理解为在该控制信道上发送控制信息，当网络设备在控制资源集合1上发送控制信道时，也可理解为在控制资源集合1上发送控制信息。
另外，在NR标准中，控制信道在控制资源集合上，可以使用一个或多个CCE进行传输。这里所说的多个CCE例如可以为2个、4个或8个CCE。其中，一个CCE由多个REG组成，例如，一个CCE由4个REG或者6个REG组成。图4为一种REG的示意图。如图4所示，每个REG在频域上由12个连续的子载波组成，在时域上由一个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号组成，即由12个频域上连续的RE组成。也就是说，每个REG在频域占用的带宽与一个RB占用的带宽相同。
网络设备在向终端设备发送控制信道时，需要在该终端设备对应的控制资源集合上，对控制信道进行CCE到REG的资源映射。目前，NR支持如下几种CCE到REG的资源映射方式：连续式资源映射方式(Localized)、分布式资源映射方式(Distributed)、频域优先资源映射方式(Frequency-first)、时域优先资源映射方式(Time-first)。在使用Localized进行CCE到REG的资源映射时，属于同一个CCE的REG在下行传输资源的频域上是连续映射的。在使用Distributed进行CCE到REG的资源映射时，属于同一个CCE的REG在下行传输资源的频域上是离散映射的。在使用Frequency-first进行CCE到REG的资源映射时，属于同一个CCE的REG在下行传输资源上的映射顺序是先频域后时域。在使用Time-first进行CCE到REG的资源映射时，属于同一个CCE的REG在下行传输资源上的映射顺序是先时域频域后频域。另外，上述几种CCE到REG的资源映射方式在时域上和频域上均支持REG绑定(REG bundling)，每个REG bundling包括属于同一CCE的多个REG。在对控制信道进行CCE到REG的资源映射时，频域上的一个REG bundling的所有REG在下行传输资源的频域上是连续映射的，时域上的一个REG bundling的所有REG在下行传输资源的时域上是连续映射的，其中频域上的REG bundling大小(size)可看作控制信道的频域资源调度粒度。
网络设备在控制资源集合上，采用不同的上述CCE到REG的映射方式，以及，控制信道在时域上所占的符号不同时，频域上的REG bundling大小就可能不一样，而在控制信道进行资源映射时，控制区域中会存在空闲的资源。
目前，在NR标准中，允许数据信道复用控制区域的空闲资源，以提高资源利用率。即，控制区域上的空闲资源可以用于传输数据信道。其中，这里所说的控制区域的空闲资源也包括控制资源集合上的空闲资源。当数据信道使用这些空闲的资源时，在现有的LTE技术中，数据信道的频域资源调度粒度仅仅与***带宽相关，因此数据信道的频域资源调度粒度与控制信道的频域REG bundling size大小有可能不一致，从而造成控制区域中有些空闲的资源不能调度给数据信道，影响资源使用效率。
本申请提供的资源映射方法，旨在解决网络设备如何为数据信道进行资源分配的技术问题。下面通过一些实施例对本申请的技术方案进行详细说明。下面这几个实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图5为本申请提供的一种资源映射方法的信令流程图。本实施例涉及的是网络设备通过控制信息指示为终端设备调度的至少一个频域资源单元，以使得终端设备可以在该至少一个频域资源单元上传输数据信道。如图5所示，该方法可以包括：
S101、网络设备生成控制信息。
其中，控制信息用于指示以下信息中的至少一种：至少一个频域资源单元所在的至少一个带宽区域、频域资源单元的粒度和频域资源单元在带宽区域中的位置，频域资源单元为网络设备与终端设备进行数据信道传输时所使用的频域资源的调度单位，资源单元的粒度对应于网络设备与终端设备进行控制信道传输时的资源单元粒度，终端设备的工作带宽包括等间隔的多个带宽区域，至少一个带宽区域为多个带宽区域中的一个或多个。
其中，控制信息可以为承载于下行控制信道上的动态控制信息，比如承载于PDCCH上的DCI，也可以是其它动态信息，本申请对此不做限定。
其中，频域资源单元可以为资源块组(Resource Block Group，RBG)，其中RBG是 一组在频域上连续的资源块，也可以是其它频域资源单元，本申请实施例对此不做限定。
其中，带宽区域的大小P可以是***预先定义的，也可以通过高层信令配置，例如无线资源控制(Radio Resource Control，RRC)信令、媒体接入控制(Media Access Control，MAC)信令等，P的单位可以为资源块，作为一种可实施的方式，P可以为频域资源单元的最大粒度。因此，***带宽可以等间隔地划分成多个带宽区域，当***带宽值不能被P整除时，剩下的频域资源仍可视为一个带宽区域。
图6为本申请提供的一种终端设备工作带宽的示意图。如图6所示，针对一个特定终端设备，由于该终端设备的工作带宽可以是***带宽的一部分，并且终端设备在***带宽的接入位置具有灵活性，上述多个带宽区域可能不是根据该特定终端设备的工作带宽进行划分的，但该终端设备的工作带宽仍然可包括多个带宽区域。可选的，终端设备工作带宽的起始位置与一个带宽区域的起始位置对齐。
可选的，上述数据信道的资源单元的粒度为控制信道的至少一个资源单元粒度中的一个资源单元粒度。详见后续描述。
由于数据信道所调度的资源单元的粒度与控制信道的粒度相同，当上述数据信道传输时复用控制信道所在的资源区域时，不会出现由于调度粒度不同产生的资源浪费现象。这里所说的控制信道所在的资源区域例如可以为前述介绍的控制区域。也就是说，上述至少一个频域资源单元在时域上，可以位于下行传输资源的控制区域上和数据区域上。通过这种方式，使得数据信道可以复用控制区域内的空闲资源进行数据传输，以提高资源利用率。
在上述信息存在一个或多个预定义的信息时，上述控制信息仅用于指示非预定的信息。例如：在频域资源单元的粒度和频域资源单元在带宽区域中的位置为预定义的信息时，上述控制信息可以用于指示至少一个频域资源单元所在的至少一个带宽区域。在上述信息不存在预定义的信息时，上述控制信息可以用于指示至少一个频域资源单元所在的至少一个带宽区域、频域资源单元的粒度和频域资源单元在带宽区域中的位置。
或者，网络设备通过上述控制信息指示上述信息中的一部分信息，网络设备采用其他指示信息来指示上述信息的其他信息。例如：，网络设备通过上述控制信息指示频域资源单元的粒度和频域资源单元在带宽区域中的位置，通过其他指示信息指示至少一个频域资源单元所在的至少一个带宽区域。其中，这里所说的其他指示信息例如可以携带在下述任一信令中发送给终端设备，例如：物理层信令、无线资源控制(Radio Resource Control，RRC)信令、媒体接入控制(Media Access Control，MAC)信令等。
S102、网络设备向终端设备发送控制信息。
应理解，该终端设备可以为一个或多个终端设备。也即，网络设备可以为每个终端设备发送对应的控制信息，比如为每个终端设备发送控制信息所在的控制信道，也可以为多个终端设备发送公共或广播控制信息，比如为一组终端设备发送控制信息所在的公共控制信道(例如：Group-common PDCCH)。
S103、终端设备接收该控制信息。
S104、终端设备根据控制信息，在至少一个频域资源单元上传输数据信道。
例如，在控制信息指示至少一个频域资源单元所在的至少一个带宽区域，以及，频域资源单元的粒度和频域资源单元在带宽区域中的位置时，终端设备可以根据至少一个频域资源单元所在的至少一个带宽区域，以及，频域资源单元的粒度和频域资源单元在带宽区 域中的位置，确定该至少一个频域资源单元在频域的位置，进而在该至少一个频域资源单元上传输数据信道。例如：终端设备向网络设备发送上行数据信道，或者，网络设备向终端设备发送下行数据信道。
例如：在“至少一个频域资源单元所在的至少一个带宽区域，以及，频域资源单元的粒度和频域资源单元在带宽区域中的位置”存在预定义的信息时，终端设备可以根据控制信道所指示的未预定义的信息，以及，预定义的信息，得到至少一个频域资源单元所在的至少一个带宽区域，以及，频域资源单元的粒度和频域资源单元在带宽区域中的位置。进而，终端设备可以根据至少一个频域资源单元所在的至少一个带宽区域，以及，频域资源单元的粒度和频域资源单元在带宽区域中的位置，确定该至少一个频域资源单元在频域的位置，进而在该至少一个频域资源单元上传输数据信道。例如：终端设备向网络设备发送上行数据信道，或者，网络设备向终端设备发送下行数据信道。
例如：在网络设备通过上述控制信息指示上述信息中的一部分信息，采用其他指示信息来指示上述信息的其他信息时，终端设备可以通过控制信息和其他指示信息，得到至少一个频域资源单元所在的至少一个带宽区域，以及，频域资源单元的粒度和频域资源单元在带宽区域中的位置。进而，终端设备可以根据至少一个频域资源单元所在的至少一个带宽区域，以及，频域资源单元的粒度和频域资源单元在带宽区域中的位置，确定该至少一个频域资源单元在频域的位置，进而在该至少一个频域资源单元上传输数据信道。例如：终端设备向网络设备发送上行数据信道，或者，网络设备向终端设备发送下行数据信道。
本申请提供的资源映射方法，通过将***带宽划分成等间隔的多个带宽区域，使得网络设备以频域资源单元为频域资源的调度单位，在多个带宽区域的至少一个带宽区域上调度至少一个频域资源单元，作为网络设备与终端设备进行数据信道传输时所使用的频域资源，并通过控制信息来指示调度信息。由于该至少一个频域资源单元在时域上，可以位于下行传输资源的控制区域上和数据区域上。因此，通过这种方式，使得数据信道可以复用控制区域内的空闲资源进行数据传输，提高了资源利用率。
如上述实施例所说，上述频域资源单元的粒度用于表征频域资源单元在带宽区域占用的带宽。作为一种可实施的方式，上述频域资源单元的粒度可以对应于控制信道的资源单元粒度，其中，控制信道的资源单元粒度可以为频域上的REG bundling大小，其中频域上的REG bundling指的是在频域上一组连续的REG资源，也可以是其它控制信道的资源单元，本申请的实施例对此不做限定。
对于频域资源单元的粒度与控制信道的资源单元粒度的对应方式，可以包括下述两种情况：
第一种情况：控制区域中存在具有不同控制资源单元粒度的多个控制信道，终端设备的频域资源单元的粒度为所述控制信道的至少一个控制资源单元粒度中的一个控制资源单元粒度。
第二种情况：终端设备的频域资源单元的粒度与该终端设备的控制信道的控制频域资源单元(例如频域上REG bundling大小)粒度相同。
以第二情况为例，可由如下可能的实施方式：
以控制信道使用2个CCE进行传输为例，其中，每个CCE包括6个REG。该2个 CCE分别为CCE0和CCE1。CCE0包括的6个REG的索引分别为：0、1、2、3、4、5。CCE1包括的6个REG的索引分别为：6、7、8、9、10、11。
图7为本申请提供的一种资源映射示意图。如图7所示，该终端设备在控制信道的资源映射方式为连续式资源映射方式(Localized)和频域优先资源映射方式(Frequency-first)，控制信道在时域上占用1个OFDM符号，CCE在频域上的一个REG bundling的大小(size)为6，则该终端设备数据信道的RBG大小为6。
图8为本申请提供的另一种资源映射示意图。如图8所示，该终端设备在控制信道的资源映射方式为分布式资源映射方式(Distributed)和频域优先资源映射方式(Frequency-first)，控制信道在时域上占用1个OFDM符号，CCE在频域上的一个REGbundling的大小(size)为2，则该终端设备数据信道的RBG大小为2。
图9为本申请提供的又一种资源映射示意图。如图9所示，该终端设备在控制信道的资源映射方式为分布式资源映射方式(Distributed)和频域优先资源映射方式(Frequency-first)，控制信道在时域上占用1个OFDM符号，CCE在频域上的一个REGbundling的大小(size)为3，则该终端设备数据信道的RBG大小为3。
图10为本申请提供的又一种资源映射示意图。如图10所示，该终端设备在控制信道的资源映射方式为连续式资源映射方式(Localized)和时域优先资源映射方式(Time-first)，控制信道在时域上占用3个OFDM符号，CCE在频域上的一个REG bundling的大小(size)为2，则该终端设备数据信道的RBG大小为3。
图11为本申请提供的又一种资源映射示意图。如图11所示，该终端设备在控制信道的资源映射方式为连续式资源映射方式(Localized)和时域优先资源映射方式(Time-first)，控制信道在时域上占用2个OFDM符号，CCE在频域上的一个REG bundling的大小(size)为3时，则该终端设备数据信道的RBG大小为3。
图12为本申请提供的又一种资源映射示意图。如图12所示，该终端设备在控制信道的资源映射方式为分布式资源映射方式(Distributed)和时域优先资源映射方式(Time-first)，控制信道在时域上占用2个OFDM符号时，CCE在频域上的一个REG bundling的大小(size)为1，则该终端设备数据信道的RBG大小为1。
图13为本申请提供的又一种资源映射示意图。如图13所示，该终端设备在控制信道的资源映射方式为分布式资源映射方式(Distributed)和时域优先资源映射方式(Time-first)，控制信道在时域上占用3个OFDM符号，CCE在频域上的一个REG bundling的大小(size)为1，则该终端设备数据信道的RBG大小为1。
通过这种方式，可以使数据信道在频域上的资源映射粒度与控制信道在频域上的资源映射粒度保持一致。
频域资源单元的粒度可以对应于控制信道的资源单元粒度，带宽区域的大小可以预配置或高层信令配置，上述控制信息用于指示至少一个频域资源单元所在的至少一个带宽区域、频域资源单元的粒度和频域资源单元在带宽区域中的位置为例，介绍上述网络设备通过控制信息指示这些信息的实现方式。可以包括下述两种情况：
第一种情况：在本实施例中，网络设备和终端设备中可以预定义有第一资源映射模式集合。其中，该第一资源映射模式集合包括至少一个资源映射模式。每个资源映射模式包括频域资源单元的粒度，以及该频域资源单元在带宽区域中的一种频域位置。因此，上述 网络设备可以获取上述第一资源映射模式集合。
因此，上述网络设备可以根据在终端设备的工作带宽上的所有控制信道的资源调度情况(包括发送给当前终端设备的控制信道，以及发送给其他终端设备的控制信道)，从多个带宽区域中选择至少一个能够为终端设备调度的带宽区域。然后，网络设备可以将控制信道在进行资源映射时所使用的REG绑定的大小，选择频域资源单元的粒度。最后，网络设备可以根据每个带宽区域上的空闲资源所在的频域位置，以及，频域资源单元的粒度，在上述第一资源映射模式集合中选择一个资源映射模式，以使得数据信道可以最大化的复用控制区域内的空闲频域资源进行数据传输，提高了资源利用率。
则在上述场景下，上述控制信息可以包括第一信息域和第二信息域。
其中，第一信息域用于指示至少一个频域资源单元所在的至少一个带宽区域。本实施例不限定上述第一信息域指示至少一个频域资源单元所在的至少一个带宽区域的方式。在本申请的一种实现方式中，上述第一信息域可以包括用于指示至少一个频域资源单元所在的至少一个带宽区域的位图。该位图的每个比特对应一个带宽区域。也就是说，上述终端设备的工作带宽划分了多少个带宽区域，位图就有多少比特。可选的，当位图中的某一比特为1时，说明该比特对应的带宽区域为频域资源单元所在的带宽区域。或者，当位图中的某一比特为0时，说明该比特对应的带宽区域为频域资源单元所在的带宽区域，具体可以根据***设定确定。
其中，第二信息域用于指示第一资源映射模式集合中的某一资源映射模式，以通过所指示的资源映射模式，来指示该资源映射模式所指的频域资源单元的粒度，以及该频域资源单元在带宽区域中的频域位置。可选的，上述第一资源映射模式集合包括的至少一个资源映射模式中的每个资源映射模式对应一个标识，上述第二信息域可以通过携带某一资源映射模式对应的标识的方式，来指示该资源映射模式。上述所说的标识例如可以为任一能够唯一标识一个资源映射模式的标识。例如：该标识可以为每个资源映射模式在第一资源映射模式集合的索引号，还可以为每个资源映射模式的名称等。上述图13示出的是以每个资源映射模式在第一资源映射模式集合的索引号，作为每个资源映射模式对应的标识的示意图。
需要说明的是，第一信息域和第二信息域可以合并成一个信息域，即第一信息域和第二信息域可以是一个信息域中的两个字段。
需要说明的是，第二信息域的比特数根据可根据第一资源映射模式集合中第一资源映射模式的数目确定。
相应地，终端设备在接收到网络设备发送的控制信息后，也可以先获取第一资源映射模式集合，以结合第一资源映射模式集合和控制信息，确定控制信息所指示的该至少一个频域资源单元在频域的位置，进而在该至少一个频域资源单元上传输数据信道。
图14为本申请提供的一种第一资源映射模式集合的示意图。示例性的，以频域资源单元的粒度为6个RB、3个RB、2个RB或1个RB为例，此时，上述频域资源单元的最大粒度为6个RB。假定每个带宽区域包括6个RB资源。则在场景下，第一资源映射模式集合所包括的资源映射模式可以如图14所示。其中，每个资源映射模式对应的标识为每个资源映射模式在第一资源映射模式集合的索引。如果频域资源单元为资源块组RBG，则RBG的大小可以为1，2，3，6。
图14中每一行表示一个资源映射模式，其中，被线条填充的方格为频域资源单元。以索引号0的资源映射模式为例，说明在该资源映射模式中，频域资源单元的粒度为6个RB，该频域资源单元在带宽区域中的频域位置为该带宽区域的所有RB。以索引号4的资源映射模式为例，说明在该资源映射模式中，频域资源单元的粒度为2个REG，该频域资源单元在带宽区域中的频域位置为该带宽区域的第3个RB和第4个RB。以索引号8的资源映射模式为例，说明在该资源映射模式中，频域资源单元的粒度为1个RB，在该宽带宽区域中可以包括2个频域资源单元，其中，一个频域资源单元在带宽区域中的频域位置为该带宽区域的第3个RB，另一个频域资源单元在带宽区域中的频域位置为该带宽区域的第6个RB。且由于第一资源映射模式集合中第一资源映射模式的数目为9，则第二信息域的比特数为4。
需要说明的是，上述图14所示的带宽区域的大小仅为一种示意，本申请并不以此为限。可选的，当带宽区域的较大时，网络设备可以根据频域资源单元的粒度，在一个带宽区域中调度一个或多个频域资源单元等，其实现方式和原理与上述实施例类似，对此不再赘述。
第二种情况：与上述第一种情况不同的是，第一种情况中所示出的第一资源映射模式集合所包括的资源映射模式，可以适配控制信道的任一CCE到REG的资源映射方式。而在本实施例中，第一资源映射模式集合对应控制信道的一种CCE到REG的资源映射方式。也就是说，网络设备中可以预定义有多个备选资源映射模式集合。其中，每个备选资源映射模式集合对应的控制信道的一种CCE到REG的资源映射方式。每个备选资源映射模式集合包括至少一个资源映射模式。任意两个备选资源映射模式集合所包括的资源映射模式可以不完全相同。也就是说，任意两个备选资源映射模式集合中可以存在相同的资源映射模式。每个备选资源映射模式集合不同。
因此，上述网络设备可以根据在终端设备的工作带宽上的所有控制信道的资源调度情况(包括发送给当前终端设备的控制信道，以及发送给其他终端设备的控制信道)，从多个带宽区域中选择至少一个能够为终端设备调度的带宽区域。然后，网络设备可以根据控制信道的CCE到REG的资源映射方式，从多个备选资源映射模式集合中选择出第一资源映射模式集合。最后，网络设备可以将控制信道在进行资源映射时所使用的REG绑定的大小，选择频域资源单元的粒度。网络设备根据每个带宽区域上的空闲资源所在的频域位置，以及，频域资源单元的粒度，在上述第一资源映射模式集合中选择一个资源映射模式，以使得数据信道可以最大化的复用控制区域内的空闲频域资源进行数据传输，提高了资源利用率。
则在上述场景下，当上述终端设备也预定义有多个备选资源映射模式集合时，上述控制信息可以包括第一信息域、第二信息域和第三信息域。其中，第一信息域用于指示至少一个频域资源单元所在的至少一个带宽区域，第二信息域用于指示第一资源映射模式集合中的某一资源映射模式，第三信息域用于从多个备选资源映射模式集合中指示所述第一资源映射模式集合。可选的，上述多个备选资源映射模式集合包括的每个资源映射模式集合对应一个标识，上述第三信息域可以通过携带某一资源映射模式集合对应的标识的方式，来指示该资源映射模式集合。上述所说的标识例如可以为任一能够唯一标识一个资源映射模式集合的标识。例如：索引号、名称等。
相应地，终端设备在接收到网络设备发送的控制信息后，可以根据第三控制信息，从多个备选资源映射模式集合中获取第一资源映射模式集合，以结合第一资源映射模式集合和控制信息的第一信息域和第二信息域，确定控制信息所指示的该至少一个频域资源单元在频域的位置，进而在该至少一个频域资源单元上传输数据信道。
或者，上述控制信息仍然只有上述第一信息域和上述第二信息域。上述网络设备在获取第一资源映射模式集合之后，可以向终端设备发送指示信息。该过指示信息用于从多个备选资源映射模式集合中指示第一资源映射模式集合。这样，终端设备可以将指示信息，以及，控制信息结合在一起使用，以从多个备选资源映射模式集合中确定第一资源映射模式集合，然后基于第一信息域和第二信息域，确定该至少一个频域资源单元在频域的位置，进而在该至少一个频域资源单元上传输数据信道。可选的，上述指示信息可以携带在高层信令中发送给终端设备，例如：物理层信令、无线资源控制(Radio Resource Control，RRC)信令、媒体接入控制(Media Access Control，MAC)信令等。当上述指示信息携带在MAC信令中时，上述指示信息具体可以携带在MAC控制元素(Control Element，CE)中。
相应地，终端设备在接收到网络设备发送的指示信息和控制信息后，可以根据指示信息，从多个备选资源映射模式集合中获取第一资源映射模式集合，以结合第一资源映射模式集合和控制信息的第一信息域和第二信息域，确定控制信息所指示的该至少一个频域资源单元在频域的位置，进而在该至少一个频域资源单元上传输数据信道。
图15为本申请提供的另一种第一资源映射模式集合的示意图。图16为本申请提供的又一种第一资源映射模式集合的示意图。假定上述多个备选资源映射模式集合包括第一资源模式集合和第二资源模式集合。其中，第一资源映射模式集合对应控制信道的CCE到REG的资源映射方式为：频域优先资源映射模式。第二资源映射模式集合对应控制信道的CCE到REG的资源映射方式为：时域优先资源映射模式。
继续以频域资源单元的粒度为6个RB、3个RB、2个RB或1个RB为例，此时，上述频域资源单元的最大粒度为6个RB。假定每个带宽区域包括6个RB。
如前述实施例所说，在采用频域优先资源映射模式，对控制信道进行资源映射时，在频域上的REG bundling的大小可能为2、3、6，因此，第一资源映射模式集合所包括的资源映射模式可以如图15所示。其中，每个资源映射模式对应的标识为每个资源映射模式在第一资源映射模式集合的索引。
如前述实施例所说，在采用时域优先资源映射模式，对控制信道进行资源映射时，在频域上的REG bundling的大小可能为1、2、3。因此，第二资源映射模式集合所包括的资源映射模式可以如图16所示。其中，每个资源映射模式对应的标识为每个资源映射模式在第一资源映射模式集合的索引。
需要说明的是，上述图15和图16所示的带宽区域的大小仅为一种示意，本申请并不以此为限。可选的，当带宽区域的较大时，网络设备可以根据频域资源单元的粒度，在一个带宽区域中调度一个或多个频域资源单元等，其实现方式和原理与上述实施例类似，对此不再赘述。
本申请提供的资源映射方法，通过将***带宽划分成等间隔的多个带宽区域，使得网络设备以频域资源单元为频域资源的调度单位，在多个带宽区域的至少一个带宽区域上调度至少一个频域资源单元，作为网络设备与终端设备进行数据信道传输时所使用的频域资 源，并通过控制信息来指示调度信息。由于该至少一个频域资源单元在时域上，可以位于下行传输资源的控制区域上和数据区域上。因此，通过这种方式，使得数据信道可以复用控制区域内的空闲资源进行数据传输，提高了资源利用率。

处理器1180是手机的控制中心，利用各种接口和线路连接整个手机的各个部分，通过运行或执行存储在存储器1120内的软件程序和/或模块，以及调用存储在存储器1120内的数据，执行手机的各种功能和处理数据，从而对手机进行整体监控。可选的，处理器1180可包括一个或多个处理单元；例如，处理器1180可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作***、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器1180中。
