下面将对本申请实施例涉及的术语进行简单介绍。
符号：包含但不限于正交频分复用(orthogonal frequency division multiplexing，OFDM)符号、稀疏码分多址技术(sparse code multiplexing access，SCMA)符号、过滤正交频分复用(filtered orthogonal frequency division Multiplexing，F-OFDM)符号、非正交多址接入(non-orthogonal multiple access，NOMA)符号等，本申请实施例在此不作限制。
子帧：一个子帧在频域上占用整个系统带宽的时频资源、在时域上为一固定时间长度的时频资源单元，例如1ms。
时隙：时隙是指一个基本的时频资源单元，在时域上占用连续的7个符号。本申请实施例在此不作限制。
子载波宽度：频域上最小的粒度。例如，在LTE系统中，1个子载波的子载波宽度为15kHz，在5G系统中，1个子载波宽度可能为15kHz，30kHz，或60kHz等。本申请实施例在此不作限制。
物理资源块(physical resource block，PRB)：频域上占用的P个连续的子载波，在时域上占用的资源为连续的Q个OFDM符号。其中P和Q为大于1的自然数。例如，一个物理资源块在频域上可占用12个连续的子载波，在时域上可占用7个连续OFDM符号，其中，P＝12，Q＝7；或者，P＝12，Q＝14。本申请实施例在此不作限制。
资源单元组(resource element group，REG)：频域上占用的P个连续的子载波，在时域上占用的资源为连续的Q个OFDM符号。其中P为大于1的自然数。例如，一个资源单元组在频域上可占用12个连续的子载波，在时域上可占用1个OFDM符号，其中，P＝12，Q＝1。本申请实施例在此不作限制。
控制信道单元(control channel element，CCE)：对应多个资源单元组，一个控制信道单元对应的资源单元组的数量固定，例如，6。本申请实施例在此不作限制。
终端设备初始接入系统时，需要检测同步信号块，图1是同步信号块结构的示意图，从图1中可以看出，同步信号块包括同步信号和广播信道。同步信号包括主同步信号(primary synchronization signal，PSS)和辅同步信号(secondary synchronization signal，SSS)，同步信号以同步信号序列的格式发送的，不同的同步信号序列对应不同小区标识。广播信道占24个PRB，主同步信号和辅同步信号占12个PRB，同步信号块在时域上占4个符号长度。终端设备接收广播信道承载的广播信息获得控制信道所在的时频资源，控制信道所在的时频资源内至少包括公共搜索空间，公共搜索空间为服务小区内，终端设备接收广播信令的时频资源，而广播信令包括调度寻呼信息的控制信息和指示随机接入应答信息的控制信息中的至少一种。
在LTE系统中，广播信息承载系统带宽信息，而系统带宽信息用于指示控制信道资源 集合的频域资源，例如，广播信息中包括3比特信息，分别对应系统带宽中包括{6,15,25,50,75,100}个物理资源块，或对应{1.4MHz，3MHz，5MHz,10MHz,15MHz,20MHz}带宽值。
在5G系统中，系统带宽信息不会包括在广播信息中，因此用户设备无法获取接入带宽信息。此外，有相关技术方案提出，广播信息指示的控制信道资源集合占用连续的频域资源，如图2所示，图2是现有技术中公共搜索空间的时频资源的示意图，图2中，横轴为频域，每个小区的公共搜索空间(common search space，CSS)由多个CCE组成，例如，8个，其中，每个CCE在频域上包括6个PRB，所述控制信道在时域上占用1个OFDM符号，图2中的2、1、0、-1、-2分别为不同小区的控制信道的频域资源相对于广播信息的中心频点的偏移量，正值和负值分别代表相反方向的偏移量。从图2中可以看出，对于一个小区而言，控制信道所占的频域资源是连续的，即8个CCE之间没有间隔，而且，图2中所示的5个不同的小区的控制信道的频域是有部分重叠的，这样，使得控制信息容易受到邻小区的干扰，控制信道在频域上的连续，若信道环境导致信号多径较多，则传输的控制信息不容易获得频率分集增益。而且，在5G系统中，广播信息中不在包含系统带宽信息，因此，用户无法控制信道的时频资源，这样，用户便无法获得接入带宽信息。
基于上述问题，本申请实施例提供了一种信息传输的方法，可以通过同步信号块的配置信息向终端设备通知控制信道的时频资源，并且，在保证邻小区干扰较低的情况下，尽可能获得更多的频率分集增益。
图3是适用于本申请的信息传输的方法和装置的通信系统的示意图。如图3所示，该通信系统100包括网络设备102，网络设备102可包括多个天线例如，天线104、106、108、110、112和114。另外，网络设备102可附加地包括发射机链和接收机链，本领域普通技术人员可以理解，它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、编码器、解复用器或天线等)。
网络设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而，可以理解，网络设备102可以与类似于终端设备116或122的任意数目的终端设备通信。终端设备116和122可以是，例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA和/或用于在无线通信系统100上通信的任意其它适合设备。
如图3所示，终端设备116与天线112和114通信，其中天线112和114通过前向链路118向终端设备116发送信息，并通过反向链路120从终端设备116接收信息。此外，终端设备122与天线104和106通信，其中天线104和106通过前向链路124向终端设备122发送信息，并通过反向链路126从终端设备122接收信息。
例如，在FDD系统中，例如，前向链路118可利用与反向链路120所使用的不同频带，前向链路124可利用与反向链路126所使用的不同频带。
再例如，在TDD系统和全双工(full duplex)系统中，前向链路118和反向链路120可使用共同频带，前向链路124和反向链路126可使用共同频带。
被设计用于通信的每个天线(或者由多个天线组成的天线组)和/或区域称为网络设备102的扇区。例如，可将天线组设计为与网络设备102覆盖区域的扇区中的终端设备通信。在网络设备102通过前向链路118和124分别与终端设备116和122进行通信的过程 中，网络设备102的发射天线可利用波束成形来改善前向链路118和124的信噪比。此外，与网络设备通过单个天线向它所有的终端设备发送信号的方式相比，在网络设备102利用波束成形向相关覆盖区域中随机分散的终端设备116和122发送信号时，相邻小区中的移动设备会受到较少的干扰。
在给定时间，网络设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时，无线通信发送装置可对数据进行编码以用于传输。具体地，无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中，传输块可被分段以产生多个码块。
此外，该通信系统100可以是PLMN网络或者D2D网络或者M2M网络或者其他网络，图3只是举例的简化示意图，网络中还可以包括其他网络设备，图3中未予以画出。
下面结合图4详细说明本申请提供的信息传输的方法，图4是本申请一个实施例的信息传输的方法200的示意性流程图，该方法200可以应用在图3所示的场景中，当然也可以应用在其他通信场景中，本申请实施例在此不作限制。
如图4所示，该方法200包括：
S210，终端设备接收控制信道资源集合的配置信息，该配置信息用于指示控制信道的资源集合，该配置信息包括该控制信道的时频资源块的数量和相邻两个时频资源块的间隔中的至少一个。
S220，该终端设备根据该配置信息确定该控制信道的时频资源。
S230，该终端设备在该控制信道的时频资源上接收控制信息。
具体而言，在S210中，终端设备在初始接入系统的过程中，会首先确定控制信道的时频资源，在确定控制信道的时频资源后，便会在该控制信道的时频资源上接收控制信息，控制信道主要用于传输控制信息或者同步数据，主要由公共搜索空间信道CSS和终端设备专属搜索空间中的一种或多种组成。公共搜索空间为服务小区内，终端设备接收广播控制信息或终端设备专属控制信息的时频资源，而广播控制信息包括调度寻呼信息的控制信息和指示随机接入应答信息的控制信息中的至少一种。同步信号块包括广播信息和同步信号，广播信息包括该控制信道资源集合的配置信息，该同步信号携带小区标识。终端设备会接收网络设备发送的控制信道资源集合的配置信息，该配置信息用于指示控制信道的资源集合，该配置信息包括该控制信道的时频资源块的数量和相邻两个时频资源块的间隔中的至少一个，例如，当该配置信息包括该控制信道的时频资源块的数量时，该相邻两个时频资源块的间隔可以是系统预定义的，或者当该配置信息包括该控制信道的相邻两个时频资源块的间隔时，该控制信道的时频资源块的数量可以是系统预定义的。该控制信道在时频资源上是不连续的，该控制信道的时频资源由多个时频资源块组成，多个时频资源块之间是存在间隔的，例如，可以在频域具有一定的间隔或者时域上具有一定的间隔。
在S220中，终端设备根据该配置信息确定该控制信道的时频资源，即根据该时频资源块的数量和相邻两个时频资源块的间隔信息，确定控制信道的时频资源。
在S230中，在确定了控制信道的时频资源，该终端设备在控制信道的时频资源上接收控制信息，根据接收到的控制信息，确定接入的小区以及小区带宽，用于后续的和网络设备进行通信。
应理解，该控制信道资源集合的配置信息除了包括该控制信道的时频资源块的数量和相邻两个时频资源块的间隔之外，还可以包括关于控制信道资源集合的其他信息或者内容，本申请实施例在此不作限制。
还应理解，该控制信道资源集合的配置信息还可以包括该控制信道资源集合的其他信息，例如。该控制信道的频域范围等信息。本申请实施例在此不作限制。
还应理解，该时频资源块可以是协议规定的任何粒度的时频资源块，例如，以PRB为单位等。本申请实施例在此不作限制。
本申请实施例提供的信息传输的方法，通过控制信道资源集合的配置信息通知控制信道的时频资源，该控制信道在时频资源上是不连续的，该控制信道的时频资源由多个时频资源块组成，多个时频资源块之间是存在间隔的，这样，即使信道环境导致信号多径较多，终端设备在该控制信道上接收控制信息时可以获得更好的频率分集增益，提高传输效率。
可选的，作为一个实施例，该时频资源块包括至少一个资源单元组REG集合，该REG集合包括时域或频域为连续或邻近的多个REG。
为了提供信道估计的精度，可以将频域或者时域连续的多个REG组成一个REG集合，或者，将频域或者时域连续的多个REG绑定(bundling)在一起组成一个REG束(bundle)。所述REG集合可称为REG束(bundle)，也可以称为REG组(group)，本申请对REG集合的具体名称不作限定。由于物理下行控制信道(physical downlink control channel,PDCCH)通过CCE映射到REG，每个CCE对应的多个REG绑定在一起组成一个或者多个REG集合。对于每个REG集合，终端设备可以利用所述REG集合而不是单个REG中可供使用的解调参考信号(demodulation reference signal，DMRS)进行联合信道估计，从而提供信道估计的精度。图5和图6是本申请实施例的REG的示意图。图5中，REG由12个RE组成，其中，有2个RE用于DMRS，10个RE用于下行控制信息(downlink control infornation，DCI),图6中，有4个RE用于DMRS，6个RE用于DCI。
该时频资源块包括至少一个REG集合，每个REG集合包括时域或频域为连续或邻近的多个REG。频域上连续的REG指的是REG编号在频域上是连续的，即相邻两个REG之间不存在子载波间隔，相邻两个REG的子载波是连续的，无空闲的频域部分。时域上连续的REG指的是REG编号在时域上是连续的，即相邻两个REG之间不存在OFDM符号间隔，相邻两个REG的OFDM符号是连续的。频域上邻近的REG指的是REG编号在频域上是不连续的，即相邻两个REG之间存在子载波间隔，该子载波间隔可以用来和其他终端设备进行通信或者传输其他信令，相邻两个REG的子载波不是连续的。时域上邻近的REG指的是REG编号在时域上是不连续的，即相邻两个REG之间存在OFDM符号间隔，相邻两个REG的OFDM符号是不连续的。
图7是本申请一个实施例REG集合的示意图。图7中，REG集合可以分别为四种不同的格式。格式1所示的REG集合包括一个REG，格式2所示的REG集合包括2个频域上连续的REG，格式3所示的REG集合包括3个频域上连续的REG，格式4所示的REG集合包括6个频域上连续的REG。
图8是本申请另一个实施例REG集合的示意图。REG集合可以分别为2种不同的格式。格式5所示的REG集合包括2个时域上连续的REG，格式6所示的REG集合包括6REG，其中，REG编号为0、1和2的三个REG在频域上连续，REG编号为7、8和9的 三个REG在频域上连续，REG编号为0和7的REG在时域上连续，REG编号为1和8的REG在时域上连续，REG编号为2和9的REG在时域上连续。

应理解，从REG集合的格式可以得到频域或者时域上连续或者邻近的REG的个数。
该REG绑定大小或者REG绑定的格式可以基于控制资源集合或者搜索空间预定义，因此终端设备神和网络设备是共知的。该REG绑定大小或者REG绑定的格式也可以由网络设备通过信令通知给终端设备，例如通过高层信令,如无线资源控制协议(radio resource control,RRC)信令通知给终端设备。例如,可以基于控制资源集合或者搜索空间配置信息通知终端设备。
可选的，作为一个实施例。该至少一个REG集合中任意一个REG集合满足下列条件中的至少一个：频域上连续或者邻近的m个PRB，m为正整数，或者时域上连续或者邻近的n个符号，n为正整数。
例如，m可以取值为1、2、3、6、12等或者2、4、8、16，n可以取值为1、2、3等。
需要指出的是，此处该频域上邻近是指在控制资源集合配置的多个RB可能在频域上不连续，但是按照频域升序或者降序排列后，其索引可以连续。此处该时域上邻近是指在控制资源集合配置的多个RB可能在时域上不连续，但是按照时域升序或者降序排列后，其索引可以连续。
该时频资源块包括至少一个REG集合。例如，该控制信道在频域上包括多个REG集合，该多个REG集合中相邻的两个REG集合存在间隔，该间隔包括至少一个不为0的值。即对于一个小区来说，控制信道在频域上是不连续的，组成控制信道的时频资源的多个REG集合之间是具有间隔的，该间隔的值可以预定义，或者可以根据不同的情况配置成不同的值。该间隔的值至少包括一个不为0的值，若间隔的值为0，则相当于控制信道的时频资源在频域上是连续的。该间隔的值可以包括多个，多个间隔的值可以相同,也可以不相同。
下面结合图10详细说明本申请实施例的信息传输的方法，图10是本申请一个实施例的控制信道资源集合的示意图，如图5所示，控制信道资源集合在时域上仅包括1个OFDM符号，且在整个频域上占了48个REG，即REG的编号从0到47，但是控制信道在频域并不是连续的，控制信道在频域上总共包括4个REG集合，相邻两个REG集合之间是具有间隔的，即有4个间隔，每个间隔包括6个REG，而每个REG集合也包括频域上连续的6个REG，即终端设备在这4个REG集合所在的频域上接接收控制信息。
应理解，图10所示的控制信道的频域的示意图仅是本申请实施例的一个具体例子，而不应对本申请实施例造成任何限制。例如，控制信道在整个频域上也可以占据其他数目的REG,控制信道在频域上也可包括其他数目的REG集合等，多个间隔也可以不相同。该间隔的频域可以大于REG集合对应的频域，可以等于REG集合对应的频域，也可以小于REG集合对应的频域。本申请实施例在此不作限制。
还应理解，上述的控制信道在频域上的占据的频域资源的单位是REG集合或者REG， 在本申请的实施例中，控制信道在频域上的占据的频域资源的单位也可以是PRB或者PRB集合，或者CCE等，本申请实施例在此不作限制。
可选的，作为一个实施例。该REG集合包括N个REG，其中，N的值为1、2、3、2或3的正整数倍数中的任意一个。
具体而言，REG集合是由REG组成的，该REG包括时域一个OFDM符号，频域上连续的12个子载波。而该REG集合可以包括N个REG，N的值为1、2、3、2或3的正整数倍数中的任意一个。即该REG集合可以由2个REG组成，由3个REG组成，或者由6个REG组成等，只要组成REG集合的REG个数为1、2、3、2或3的正整数倍数即可。
应理解，该REG集合也可以包括其他个数的REG，本申请实施例在此不作限制。
可选的，作为一个实施例。该相邻时频资源块的间隔在频域上包括整数个REG对应的频域资源或整数个该REG集合对应的频域资源。
具体而言，该相邻时频资源块的频域间隔的粒度可以是以REG为单位的，即该频域间隔可以包括整数个REG对应的频域资源，例如，该频域间隔为5个REG对应的频域资源，由于该频域间隔包括多个不同的值，因此，该频域间隔对应频域资源也可以不同。该频域间隔可以大于一个REG集合对应的频域，可以等于一个REG集合对应的频域，也可以小于一个REG集合对应的频域。
应理解，该频域间隔的粒度也可以是以PRB所占频域大小或者其他频域单元为单位，本申请实施例在此不作限制。
可选的，作为一个实施例。该相邻时频资源块的间隔在频域包括整数个REG集合对应的频域资源。
具体而言，该相邻时频资源块的频域间隔的粒度可以是以REG集合为单位的，即该频域间隔可以包括整数个REG集合对应的频域资源，例如，该频域间隔为5个REG集合对应的频域资源，当该频域间隔为1个REG集合对应的频域资源时，即该频域间隔的频域和REG集合对应的频域相同，即为图5所示的控制信道的资源。
应理解，该频域间隔的粒度也可以是以PRB集合或者其他频域单元集合为单位，本申请实施例在此不作限制。
可选的，作为一个实施例，该终端设备根据该相邻时频资源块的间隔和/或至少一个REG集合，确定该终端设备的接入带宽信息。
具体而言，终端设备接入系统的带宽信息可以由控制信道在频域上的资源确定，由于控制信道在频域上是有间隔的，因此，可以由该间隔和该至少一个时频资源块来确定，以图10所示的控制信道的频域示意图为例进行说明，在图10中，相邻的两个时频资源块之间间隔6个REG，即该间隔为6个REG对应的频域，4个时频资源块中，每个时频资源块包括11个REG，即具有4个间隔和4个时频资源块，因此，该终端设备的接入带宽为4x6+4x6＝48,即终端设备的接入系统的带宽为48个REG对应的带宽值。
或者，终端设备根据该间隔来确定终端设备接入系统的带宽信息，例如，可以根据预定义，确定该间隔对应的频域资源的K倍为终端设备接入系统的带宽，又例如，可以是通过和该间隔对应的频域资源有关的方程来确定终端设备接入系统的带宽信息，本申请实施例在此不作限制。同样，对于终端设备根据至少一个时频资源块确定终端设备接入系统的 带宽信息，也可以是根据预定义，确定至少一个时频资源块对应的频域资源的K倍为终端设备接入系统的带宽，又例如，可以是通过和至少一个时频资源块对应的频域资源有关的方程来确定终端设备接入系统的带宽信息等，本申请实施例在此不作限制。
可选的，作为一个实施例，该资源集合的频域中心位置与同步信号块的频域中心位置的偏移的偏移量为预定义的，或者由该配置信息指示，该同步信号块包括该配置信息。
具体而言，由于不同的小区的控制信道的频域是可能是有部分重叠的，即不同小区的控制信道在频域上可能是有重叠部分，这样，不同小区的在各自控制信道上接收控制信息时容易受到邻小区的干扰。在本申请实施例中，每个小区的控制信道的频域中心位置相对于该广播信息的频域中心位置存在偏移，不同的小区的偏移值是不同的。即该资源集合的频域中心位置与同步信号块的频域中心位置的存在偏移，该偏移的偏移量与小区标识对应。同步信号块包括广播信息和同步信号，广播信息包括该控制信道资源集合的配置信息，该同步信号携带小区标识。即该终端设备根据该同步信号中的小区标识，确定该偏移的偏移量，便可以确定该控制信道的时频资源。小区的标识是承载在网络设备发送的同步信号块上的。该资源集合的频域中心位置相对于同步信号块的频域中心位置的偏移的偏移量是根据该同步信号块中的小区标识确定的。这样，对于不同的小区的控制信道的频域就不会重叠或者重叠较少，可以降低不同小区的在各自控制信道上接收控制信息时容易受到邻小区的干扰。而该偏移的偏移值可以是系统预定义的，即协议规定好的，或者由可以由该配置信息指示。本申请实施例在此不作限制。
可选的，所述控制信道资源集合的频域中心位置与同步信号块的频域中心位置的偏移的偏移量的个数，可由所述时频资源块和相邻两个时频资源块的间隔确定。
根据所述时频资源块和相邻两个时频资源块的间隔确定所述终端设备的接入带宽，根据接入带宽可导出控制信道资源集合相对于频率偏移量的个数。
具体的，在一种可实现方法中，如图11所示，小区1的控制信道资源集合为20MHz，对应的时域偏移个数为4；小区2的接入带宽为10MHz，对应的时域偏移为2个。
图11是本申请一个实施例的不同小区的控制信道资源集合的频域偏移的示意图，图11中，小区1的控制信道资源集合为20MHz,小区2的控制信道资源集合为10MHz,小区1和小区2的控制信道资源集合在频域上都是不连续的，小区1的控制信道资源集合和小区2的控制信道资源集合的频域中心相对于该同步信号块的频域中心位置各自存在一个偏移值，小区1的控制信道资源集合的频域中心相对于该同步信号块的频域中心位置向左偏移了一个REG集合所对应的频域，小区2的控制信道资源集合的频域中心相对于该同步信号块的频域中心位置向右偏移了一个REG集合所对应的频域，偏移之后，小区1的控制信道资源集合的和小区2的控制信道资源集合在频域上就重叠的比较少，或者不重叠。可以降低不同小区的在各自控制信道资源集合上接收控制信息时容易受到邻小区的干扰。
图12是本申请另一个实施例的不同小区的控制信道资源集合的频域偏移的示意图，图12中，小区1的控制信道资源集合在频域上也是不连续的，具有间隔，因此，可以配置小区2在小区1的控制信道资源集合的频域间隔部分接收控制信息，即小区1的控制信道资源集合的频域间隔部分为小区2的控制信道资源集合频域部分。这样，小区1的控制信道资源集合的频域和小区2的控制信道资源集合的频域就不会重叠，也可以降低不同小 区的在各自控制信道资源集合上接收控制信息时容易受到邻小区的干扰。
应理解，上述的图11和图12仅以两个小区的控制信道资源集合的频域不重叠为例来说明不同小区的控制信道在频域上不叠进行说明，但本申请实施例并不限于此，例如，可以是更多的小区的控制信道在频域上不重叠，即相对于广播信息的频域中心位置存在不同的偏移值，本申请实施例在此不作限制。
本申请实施例提供的信息传输的方法，对于一个小区的控制信道在整个频域是不连续的，具有频域间隔，终端设备在这种格式的控制信道上接收控制信息，也可以获得更好的频率分集增益，提高传输效率。而对于不同的小区的控制信道的频域中心位置相对于该控制信道的资源集合的频域中心位置存在不同的偏移值，即不同小区的控制信道的频域不会重叠，可以降低不同小区的在各自的控制信道上接收控制信息时受到的邻小区干扰。并且，通过控制信道资源集合的配置信息来指示控制信道的时频资源，即确定控制信道的频域资源，解决了5G中无法通知控制信道的时频资源的问题。
应理解，该时频资源块的数量和该相邻两个时频资源块的间隔中的至少一个为预定义。
具体而言，控制信道包括的时频资源块的数量可以是协议预定义的，当控制信道包括的时频资源块的数量是协议预定义时，可以不用向终端设备通过信令进行通知，这样，可以节省信令开销。或者。控制信道包括的时频资源块的数量也可以是网络设备配置的，当网络设备配置时频资源块的数量的时，可以配置多个不同数量的时频资源快，并且通过该配置信息指示给终端设备其中的某一个数量的时频资源块。这样可以提供资源配置的灵活性，提高频谱的利用率。
同样，该相邻两个时频资源块的间隔也可以是协议预定义的，也可以是网络设备配置的，并且通过该配置信息指示给终端设备。本申请实施例在此不作限制。
应理解，该时频资源块包括的该REG集合的个数和该REG集合包括的REG个数中的至少一个为预定义，或者由该配置信息指示。
具体而言，时频资源块包括的该REG集合的个数，可以是协议预定义的，也可以是网络设备配置的，并且通过该配置信息指示给终端设备。该REG集合包括的REG个数也可以是协议预定义的，也可以是网络设备配置的，并且通过该配置信息指示给终端设备。本申请实施例在此不作限制。

具体而言，网络设备在终端设备在初始接入系统的过程中，会向终端设备通知控制信道的时频资源，用于终端设备在该时频资源上接收控制信息，控制信道主要用于传输信令或者同步数据。由于在5G系统中，广播信息中不再包含系统带宽信息。因此，在S310中，网络设备会生成控制信道资源集合的配置信息，该配置信息用于指示控制信道的资源 集合。该控制信道包括公共搜索空间CSS、广播信道和专用控制信道，该配置信息包括该控制信道的时频资源块的数量和相邻两个时频资源块的间隔中的至少一个，例如，当该配置信息包括该控制信道的时频资源块的数量时。该相邻两个时频资源块的间隔可以是系统预定义好的，或者当该配置信息包括该控制信道的相邻两个时频资源块的间隔时。该控制信道的时频资源块的数量可以是系统预定义好的。该控制信道在时频资源上是不连续的，该控制信道的时频资源由多个时频资源块组成，多个时频资源块之间是存在间隔的。例如。可以在频域具有一定的间隔或者时域上具有一定的间隔。在网络上设备生成该控制信道资源集合的配置信息后，便会向终端设备发送该配置信息，该终端设备在确定了控制信道的时频资源后，在控制信道的时频资源上接收控制信息，根据接收到的控制信息，确定接入的小区以及小区带宽，用于后续的和网络设备进行通信。

可选的，作为一个实施例，该资源集合的频域中心位置与同步信号块的频域中心位置的偏移的偏移量为预定义的，或者由该配置信息指示，该同步信号块包括该配置信息。
具体而言，由于不同的小区的控制信道的频域是可能是有部分重叠的，即不同小区的控制信道在频域上可能是有重叠部分，这样，不同小区的在各自控制信道上接收控制信息时容易受到邻小区的干扰。在本申请实施例中，每个小区的控制信道的频域中心位置相对于该广播信息的频域中心位置存在偏移，不同的小区的偏移值是不同的。即该资源集合的频域中心位置与同步信号块的频域中心位置的存在偏移，该偏移的偏移量与小区标识对应。同步信号块包括广播信息和同步信号，广播信息包括该控制信道资源集合的配置信息，该同步信号携带小区标识。即该终端设备根据该同步信号块中的小区标识，确定该偏移的偏移量。该资源集合的频域中心位置相对于同步信号块的频域中心位置的偏移的偏移量是根据所述同步信号块中的小区标识确定的。这样，对于不同的小区的控制信道的频域就不会重叠或者重叠较少，可以降低不同小区的在各自控制信道上接收控制信息时容易受到邻小区的干扰。而该偏移的偏移值可以是系统预定义的，即协议规定好的，或者由可以由该配置信息指示。本申请实施例在此不作限制。
