本发明实施例的方案可以应用于现有的蜂窝通信系统，如全球移动通讯 (英文全称可以为：Global System for Mobile Communication，英文简称可以为：GSM)，宽带码分多址(英文全称可以为：Wideband Code Division Multiple Access，英文简称可以为：WCDMA)，长期演进(英文全称可以为：Long Term Evolution，英文简称可以为：LTE)，码分多址(英文全称可以为：Code Division Multiple Access，英文简称可以为：CDMA)等系统中，所支持的通信主要是针对语音和数据通信的。通常来说，一个传统基站支持的连接数有限，也易于实现。
可选地，该网络设备为基站，该终端设备为用户设备。
本发明结合终端设备描述了各个实施例。终端设备也可以称为用户设备(英文全称可以为：User Equipment，英文简称可以为：UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备可以是无线局域网(英文全称可以为：Wireless Local Area Networks，英文简称可以为：WLAN)中的站点(英文全称可以为：STAION，英文简称可以为：ST)，可以是蜂窝电话、无绳电话、会话启动协议(英文全称可以为：Session Initiation Protocol，英文简称可以为：SIP)电话、无线本地环路(英文全称可以为：Wireless Local Loop，英文简称可以为：WLL)站、个人数字处理(英文全称可以为：Personal Digital Assistant，英文简称可以为：PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及未来5G网络中的终端设备。

此外，本发明实施例的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包 括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘，例如，压缩盘(英文全称可以为：Compact Disk，英文简称可以为：CD)、数字通用盘(英文全称可以为：Digital Versatile Disk，英文简称可以为：DVD)等，智能卡和闪存器件，例如，可擦写可编程只读存储器英文全称可以为：Erasable Programmable Read-Only Memory，英文简称可以为：EPROM)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
在本发明实施例中，通信系统使用的频域资源可以是指网络设备使用的具有规定带宽的一个载波所对应的频谱资源，其中，该载波可以包括多个子载波(Sub-carrier)，或者，该载波也可以包括多个资源块(RB，Resource Block)。
并且，在本发明实施例中，该频域资源的带宽可以根据系统要求或者协议规定任意设定，本发明并未特别限定，例如，该频域资源的带宽可以为20MHz或100MHz等。
图1示出了本发明实施例的频域资源的划分方式的一例的示意图。如图1所示，该频域资源(即，一个载波所对应的频谱资源)可以被划分为N个频域资源组(或者，也可以称为：“宽子带”)，即，图1所示的频域资源组#0～频域资源组#N，N≥2。
其中，每个频域资源组包括RB，或者，每个频域资源组包括至少至少两个子载波。
需要说明的是，在本发明实施例中，该N个频域资源组中每个频域资源组的带宽(或者说，所包括的子载波或RB的数量)可以相同也可以相异，本发明并未特别限定。
可选地，该至少两个频域资源组在该频域资源中连续分布。
具体地说，在本发明实施例中，在本发明实施例中，任意两个相邻的频域资源组彼此之间可以连续配置，或者说，任意两个相邻的频域资源组彼此之间可以不设置保护间隔，从而，能够提高带宽利用率。
应理解，以上列举的频域资源组彼此之间配置关系仅为示例性说明，本发明并未限定于此，例如，该N个频域资源组中部分或全部的彼此相邻的两个频域资源组之间也可以配置保护间隔。
可选地，至少两个频域资源组与至少两个混合自动重传请求HARQ实体一一对应，每个HARQ实体用于进行针对所对应的频域资源组的HARQ处理。
具体地说，如图2所示，在本发明实施例中，网络设备中可以配置N个混合自动重传请求(HARQ，Hybrid Automatic Repeat reQuest)实体，并且，该N个HARQ实体与N个频域资源组一一对应，即，每个HARQ实体仅用于进行所对应的频域资源组所承载的传输(包括上行传输和下行传输)的反馈处理，从而，能够避免因通过一个HARQ实体处理多个频域资源组的反馈处理而导致传输错误，能够进一步提高本发明实施例的实用性。
在本发明实施例中，该N个频域资源组彼此之间可以主从配置(即，配置方式1)，或者，该N个频域资源组彼此之间也可以独立配置(即，配置方式2)下面，分别对这两种配置方式进行详细说明。
配置方式1
可选地，该至少两个频域资源组包括主频域资源组和至少一个从频域资源组。
具体地说，由于上述N个频域资源组属于同一载波所对应的频谱资源，因此，该N个频域资源组可以属于同一小区，或者说，该N个频域资源组所对应的小区的小区配置可以相同。
从而，在本发明实施例中，可以在该N个频域资源组中设定一个(或者多个)频域资源组作为主频域资源组，例如，图1所示的频域资源组#0。
并且，可以将其他频域资源组作为从频域资源组。
需要说明的是，在本发明实施例中，该主频域资源组可以由协议规定，或者，也可以由网络设备和终端设备(包括该目标终端设备)协商确定，本发明并未特别限定。
另外，在本发明实施例中，该主频域资源组可以作为终端设备进行针对该网络设备的初始接入所使用的频域资源。
即，网络设备可以预设的用于传输系统信息，例如，主信息块(MIB，Master Information Block)的时频资源向终端设备下发主频域资源组的指示信息，例如，该主频域资源组的序号或者在频域资源中的位置等的信息，从而，终端设备可以确定该主频域资源组，并通过该主频域资源组进行接入处理。
并且，在接入后，网络设备还可以例如，根据终端设备的处理能力(即，所能够处理频谱资源的宽度)等，为该终端设备分配其他频域资源组，例如，对于处理能力较低的终端设备，可以仅使用该主频域资源组进行通信；对于处理能力较高的终端设备，可以使用该主频域资源组和一个或多个从频域资源组进行通信。
或者，在接入后，网络设备还可以例如，根据终端设备所访问的业务的业务类型(或者说，业务的带宽要求)等，为该终端设备分配其他频域资源组，例如，如果终端设备访问的是带宽要求较大的业务，则可以仅使用该主频域资源组进行通信；如果终端设备访问的是带宽要求较小的业务，则可以使用该主频域资源组和一个或多个从频域资源组进行通信。
可选地，该主频域资源组中配置有控制信道，该主频域资源组的控制信道用于传输在同一个调度周期内被使用的所有频域资源组的调度信息。
具体地说，如图3所示，可以仅在频域资源组#0(即，主频域资源组的一例)上配置控制信道，而不在从频域资源组(例如，可以包括该频域资源组#1～该频域资源组#N)中设置控制信道，并且，可以在该频域资源组#0的控制信道中，传输针对各从频域资源组的控制信息，例如，下行控制信息(DCI，Downlink Control Information)。
作为示例而非限定，当需要在一个调度周期内通过该主频域资源组的控制信道传输多个终端设备的控制信息时，该多个终端设备的控制信息可以采用例如，码分复用方式、时分复用或频分复用等方式，共享该主频域资源组的控制信道。
另外，在本发明实施例中，当需要将多个频域资源组(例如，可以包括主频域资源组和至少一个从频域资源组)分配给一个终端设备时：
例如，分配给该终端设备的每个频域资源组可以具有独立的DCI，每个DCI可以包括频域资源组指示信息(或者说，频域资源组指示域)，用于指示该DCI所调度的频域资源组。并且，每个DCI可以包括TB指示信息(或者说，TB域)，用于指示该频域资源组所承载的TB的个数。并且，每个DCI可以包括资源块指示信息(或者说，资源块指示域)，用于指示各TB所映射于该频域资源组中的具体的资源块，这里，每个频域资源组所承载的所有的TB可以承载于该频域资源组中相同的资源块，或者，每个频域资源组所承载的各TB可以分别承载于该频域资源组中不同的资源块，本发明并未特比 限定。
或者，分配给该终端设备的每个频域资源组可以共用同一DCI，即：
可选地，该目标频域资源组包括至少两个频域资源组，以及
该网络设备通过该目标频域资源组，与该目标终端设备进行无线通信，包括：
通过一个调度信息进行针对所述该目标频域资源组中的各频域资源组的资源调度。
在一种实施方式中，可以使各频域资源组的资源分配方式相同(例如，每个频域资源组所承载的TB的数量相同，并且，每个频域资源组中的用于承载TB的资源块的位置也相同)，从而通过一个DCI指示各频域资源组的资源分配方式(或者说，调度方式)。
即，可选地，所述调度信息中包括用指示所述目标频域资源组所包括的频域资源组的指示信息。
具体地说，可以在DCI中配置例如比特映射(Bitmap)等用于指示当前小区中的所有频域资源组中被分配给该目标终端设备的频域资源组的指示信息，以使目标终端设备根据DCI中承载的Bitmap，确定能够使用该Bitmap所指示的频域资源组传输信息。
或者，也可以为小区中的各频域资源组分配频域资源组标识，以使一个频域资源组标识能够唯一地指示一个小区中的一个频域资源组，从而可以在DCI中承载当前小区中被分配给该目标终端设备的频域资源组的频域资源组标识，以使目标终端设备根据DCI中承载的频域资源组标识，确定能够使用该频域资源组标识所指示的频域资源组传输信息。
在另一种实施方式中，可以使该DCI包括多个信息分片，每个部分用于指示所对应的频域资源组上的资源分配方式，例如，当为一个终端设备分配的目标频域资源组包括M(N≥M≥2)个频域资源组(例如，频域资源组#1～频域资源组#M)时，该DCI包括M个信息分片(例如，信息分片#1～信息分片#M)，信息分片#1用于指示频域资源组#1上的资源分配方式，例如，可以包括该频域资源组#1的标识，该频域资源组#1所承载的TB的数量，和该频域资源组#1中承载TB的资源块的位置等。类似地，信息分片#M用于指示频域资源组#M上的资源分配方式，例如，可以包括该频域资源组#M的标识，该频域资源组#M所承载的TB的数量，和该频域资源组#M中承载 TB的资源块的位置等。
即，可选地，该调度信息包括至少两个信息分片，所述至少两个信息分片与所述目标频域资源组包括的至少两个频域资源组一一对应，每个信息分片用于指示所对应的频域资源组上的资源分配方式。
另外，作为示例而非限定，该集中控制信道可以是物理下行控制信道(PDCCH，Physical Downlink Control Channel)，或者，增强物理下行控制信道(EPDCCH，Enhanced Physical Downlink Control Channel)等，本发明并未特别限定。
通过仅在主频域资源组中设置控制信道，并通过该控制信道传输各频域资源组(包括主频域资源组和从频域资源组)的调度信息，能够节省控制信道的资源开销，提高通信系统的数据吞吐量。
可选地，该主频域资源组中配置有上行反馈信道，该主频域资源组的上行反馈信道用于传输在同一个下行传输周期内被使用的所有频域资源组所承载的下行传输的反馈信息。

另外，作为示例而非限定，该集中上行反馈信道可以是物理上行控制信道(PUCCH，Physical Uplink Control Channel)等，本发明并未特别限定。
通过仅在主频域资源组中设置上行反馈信道，并通过该上行反馈信道传输各频域资源组(包括主频域资源组和从频域资源组)的上行反馈信息，能够节省上行反馈信道的资源开销，提高通信系统的数据吞吐量。
可选地，该主频域资源组中配置有下行反馈信道，该主频域资源组的下行反馈信道用于传输在同一个上行传输周期内被使用的所有频域资源组所承载的上行传输的反馈信息。

另外，作为示例而非限定，该集中下行反馈信道可以是物理混合自动重 传指示信道(PHICH，Physical Hybrid ARQ Indicator Channel)等，本发明并未特别限定。
通过仅在主频域资源组中设置下行反馈信道，并通过该下行反馈信道传输各频域资源组(包括主频域资源组和从频域资源组)的下行反馈信息，能够节省下行反馈信道的资源开销，提高通信系统的数据吞吐量。
需要说明的是，在使用配置方式1时，该主频域资源组中的各信道可以被系统中的需要在当前通信周期内进行通信的所有终端设备检测。
配置方式2

具体地说，如图6所示，可以在各频域资源组(例如，频域资源组#0～频域资源组#N)上均配置控制信道，并在各频域资源组的控制信道中，传输针对各频域资源组的控制信息，例如，下行控制信息(DCI，Downlink Control Information)。
另外，作为示例而非限定，该控制信道可以是物理下行控制信道(PDCCH，Physical Downlink Control Channel)，或者，增强物理下行控制信道(EPDCCH，Enhanced Physical Downlink Control Channel)等，本发明并未特别限定。

应理解，以上列举的配置方式1和配置方式2可以单独使用也可以配置使用，本发明并未特别限定，例如，可以通过配置在主频域资源组上的控制信道传输控制信息，以通知终端设备为其分配的从频域资源组，并通过配置在各从频域资源组上的控制信道传输各从频域资源组的控制信息。
以上，结合图1至图8详细说明了本发明实施例中频域资源的划分方式，下面，结合图9至图11详细说明本发明实施例的无线通信的方法。
图9示出了从网络设备角度描述的本发明一实施例的无线通信的方法100的示意性流程图。该方法100应用于使用具有规定的带宽的频域资源的通信系统，该频域资源被划分为至少两个频域资源组，每个频域资源组包括至少一个资源块，该至少两个频域资源组属于同一小区，如图9所示，该方法100包括：

该网络设备根据该终端能力信息，从该至少两个频域资源组中，确定分配给目标终端设备的目标频域资源组。
具体地说，终端设备#A可以例如，通过主频域资源组中的时频资源，将终端能力信息发送给网络设备，在本发明实施例中，该终端能力信息可以指示终端设备#A能够处理的带宽，从而，网络设备可以基于该终端能力信息为终端设备#A分配目标频域资源组。
例如，如果终端设备#A能够处理的带宽较小，则可以仅分配给终端设备#A较少的(例如，一个)频域资源组作为目标频域资源组，作为示例而非限定，此情况下，可以将上述主频域资源组作为该目标频域资源组。
再例如，如果终端设备#A能够处理的带宽较大，则可以分配给终端设备#A多个频域资源组作为目标频域资源组。
可选地，该网络设备从该至少两个频域资源组中，确定分配给目标终端设备的目标频域资源组，包括：

该网络设备根据该业务类型信息，从该至少两个频域资源组中，确定分配给目标终端设备的目标频域资源组。
具体地说，终端设备#A可以例如，通过主频域资源组中的时频资源，将业务类型信息发送给网络设备，在本发明实施例中，该业务类型信息可以 指示终端设备#A所访问的业务所需要的带宽，从而，网络设备可以基于该业务类型信息为终端设备#A分配目标频域资源组。
例如，如果该终端设备#A所访问的业务为传统的语音、短消息等业务，则其需要的带宽较小，则可以仅分配给终端设备#A较少的(例如，一个)频域资源组作为目标频域资源组，作为示例而非限定，此情况下，可以将上述主频域资源组作为该目标频域资源组。
例如，如果该终端设备#A所访问的业务为视频、高清图像等大数据业务，则可以分配给终端设备#A多个频域资源组作为目标频域资源组。
应理解，上述目标频域资源组的分配过程可以在上述接入过程中进行，也可以在接入过程完成之后进行，本发明并未特别限定。
其后，该网络设备可以向该目标终端设备发送如上所述分配的该目标频域资源组的指示信息(即，第一指示信息)。
可选地，该网络设备向该目标终端设备发送第一指示信息，包括：
该网络设备通过该主频域资源组，向该目标终端设备发送该第一指示信息。
具体地说，当如上所述划分的N个频域资源组中包括主频域资源组时，网络设备可以通过该主频域资源组(例如，该主频域资源组中的集中控制信道)向终端设备#A发送该目标频域资源组的指示信息。
应理解，以上列举的该目标频域资源组的指示信息的发送方式仅为示例性说明，本发明并未限定于此，例如，还可以通过MIB消息等向终端设备#A发送该目标频域资源组的指示信息。
在网络设备和终端设备#A双方协商确定上述目标频域资源组之后，网络设备和终端设备#A能够通过目标频域资源组进行无线通信。
在本发明实施例中，网络设备可以通过目标频域资源组上的独立控制信息，或者，主频域资源组上的集中控制信息向终端设备#A发送调度信息，并且，终端设备#A可以根据该调度信息通过目标频域资源组传输数据。
例如，在下行传输时，网络设备可以将需要发送给终端设备#A的传输块(TB，Transport Block)映射在上述调度信息所指示的目标频域资源组中的全部或部分时频资源上，从而，能够通过目标频域资源组将TB发送至终端设备#A。
再例如，在上行传输时，终端设备#A可以将需要发送给网络设备的TB 映射在上述调度信息所指示的目标频域资源组中的全部或部分时频资源上，从而，能够通过目标频域资源组将TB发送至网络设备。
下面，对TB在目标频域资源组中的映射方式进行详细说明。
在本发明实施例中，每个频域资源组可以映射至少一个TB，其中，每个频域资源组映射的TB可以相同也可以相异，本发明并未特别限定。
可选地，该目标频域资源组包括至少两个频域资源组，以及
该网络设备通过该目标频域资源组，与该目标终端设备进行无线通信，包括：
该网络设备通过该目标频域资源组，与该目标终端设备传输至少两个传输块TB，其中，该至少两个TB中的第一TB承载于该目标频域资源组中的第一频域资源组，该至少两个TB中的第二TB承载于该目标频域资源组中的第二频域资源组，第一频域资源组与该第二频域资源组不同。
具体地说，在本发明实施例中，当终端设备#A需要传输(例如，发送或接收)的TB为两个或两个以上时，可以将这些TB分别承载(或者说，映射)于不同的频域资源组。
例如，目标频域资源组中的每个频域资源组可以承载1个TB。即，如果终端设备#A需要传输N个TB，则可以为终端设备#A分配N个(例如，频域资源组#0～频域资源组#N-1)作为目标频域资源组，并且，该N个TB与N个频域资源组一一对应，即，每个频域资源组承载所对应的TB。
或者，目标频域资源组中的部分频域资源组可以承载1个TB，其他频域资源组可以承载2个(或者，2个以上)TB。
可选地该网络设备通过该目标频域资源组，与该目标终端设备进行无线通信，包括：
该网络设备通过该目标频域资源组，与该目标终端设备传输至少三个传输块TB，其中，
该目标频域资源组包括至少两个频域资源组，且该目标频域资源中的至少一个频域资源组用于承载至少两个TB；或者
该目标频域资源组包括至少三个频域资源组，该目标频域资源组中的每个该频域资源组用于承载至少一个TB。
具体地说，当目标频域资源组包括至少三个频域资源组时，在目标频域资源组所包括的每个频域资源组中可以映射有一个TB，例如，如图10所示， 当发送端设备(即，网络设备或终端设备#A中的一方)需要发送的TB的数量可以为例如，4个，并且，目标频域资源组所包括的频域资源组的数量为例如，4个时，TB#1可以映射在频域资源组#1、TB#2可以映射在频域资源组#2、TB#3可以映射在频域资源组#3、TB#4可以映射在频域资源组#4。
或者，当目标频域资源组包括至少两个频域资源组时，在目标频域资源组所包括的一个或多个频域资源组中可以映射有两个或两个以上的TB，同时，在目标频域资源组所包括的其他频域资源组中可以映射有一个TB。
再或者，当目标频域资源组包括至少两个频域资源组时，在目标频域资源组所包括每个频域资源组中可以映射有两个或两个以上的TB。
在现有技术中，在一个传输周期内，通过一个载波，最多能够传输一个终端设备的两个TB。与此相对，在本发明实施例中，通过为一个终端设备分配同一载波内的两个以上的频域资源组，在一个传输周期内，能够传输终端设备#A的三个以上的TB。因此，根据本发明实施例的无线通信的方法，能够缩短针对终端设备个体的数据传输时间。
另外，在现有技术中当通过一个载波传输一个终端设备的两个TB时，这两个TB采用空分复用方式等技术复用该一个载波内的相同的频域资源。与此相对，在本发明实施例中，通过为一个终端设备分配同一载波内的两个以上的频域资源组，能够通过不同的频域资源组传输不同的TB，无需使用空分复用等技术，能够降低网络设备和终端设备的处理要求和负担。
应理解，以上列举的映射方式仅为示例性说明，本发明并未限定于此，目标频域资源组所包括的频域资源组的数量可以任意设定，终端设备#A的TB的数量也可以任意设定，本发明并未特别限定。
