Description

一种资源配置的方法、终端通信的方法及相关设备 技术领域
本申请涉及电学领域，尤其涉及一种资源配置的方法、终端通信的方法及相关设备。
背景技术
第三代合作伙伴项目(the 3rd Generation Partnership Project，3GPP)协议定义的设备到设备(Device to Device，D2D)技术是用于设备与设备之间直接通信的技术，即两个设备之间可以不经过基站直接发送消息和相应的控制信息。目前，3GPP协议定义的D2D技术主要是面向公共安全的应用，其中定义了用于发送发现消息(discovery message)的物理旁路发现信道(Physical sidelink discovery channel，PSDCH)信道。
在典型应用场景，用户设备(User Equipment，UE)到网络的中继(UE-to-Network relay)场景中，通过中继设备(Relay User Equipment，Relay UE)中转演进型基站(evolved Node B，eNB)与远端设备(Remote User Equipment，Remote UE)之间的数据和控制信息。在3GPP协议定义的D2D技术中，发送设备和接收设备都支持全带宽的工作。例如，当***带宽是20MHz时，设备可以在20MHz频带上发送和接收发现消息。
现有技术中，中继设备在一个时间间隔上在全宽带选择一块资源用于发送discovery message，且该选择的资源可以在全频带内跳变，所以远端设备需要在全频带内接收整个工作带宽上的信号并解调。这种方式会增加远端设备的功耗。

中继终端(relay UE)向远端终端发送的discovery message(发现消息)在发现资源池中发送，将发现资源池按周期划分成若干个时频资源集合，这个周期称为discovery period。为提高远端终端接收discovery message的可靠性，在每个discovery period内，中继终端最多可以发送4次携带相同信息的discovery message，其中包括1次初次传输和3 次重传。如图2.a所示，将discovery period配置为320ms，中继设备可在PSDCH资源集合上选择资源用于发送discoverymessage。如图2.b所示，中继设备在PSDCH的一个周期内的资源集合中随机选择了一块资源用于发送discovery message。
下面对本申请实施例的流程进行描述，请参阅图3，本申请实施例资源配置方法和终端通信方法的一个方法实施例包括：
301、网络侧设备将可用带宽划分成至少两个子带；
在D2D技术中，第一终端在可用带宽上选择资源发送第一消息，其中可用带宽为用于第一终端和第二终端进行通信的频带。网络侧设备将该可用带宽进行划分得到至少两个子带，其中该至少两个子带中包括一个主子带和至少一个副子带，且网络侧设备划分该可用带宽的方式可以为均等划分或者不均等划分，即划分得到的各子带的带宽可以相同，也可以不相同，具体此处不做限定。
另外，网络侧设备可以根据第二终端的可支持带宽对可用带宽进行划分，例如第二终端所支持的宽带较窄，对应的，网络侧设备将可用带宽划分成带宽较小的各子带。实际应用中，网络侧设备划分可用带宽的依据有多种，例如网络设备确定第二终端的个数为N，则网络设备将可用带宽划分为N+1份，其中可包括1个主子带和N个副子带，故网络侧设备划分可用带宽的依据具体此处不做限定。
需要说明的是，为了便于表述，本申请中使用“子带”来表示可用带宽在频域上被划分后得到的资源集合，可以理解的是，子带包括一定频率资源和一定时间资源的资源集合。一个子带在频率上可以包括一个或多个子载波，也可以包括频率上粒度较大的一个或多个PRB，甚至一个或多个载波频率资源。实际应用中，子带也可以称为子信道、时频资源集合或者子频带，具体此处不做限定。
可选地，将可用带宽分成一个或多个子带还可以采用预配置的方式，即不需要网络侧设备对可用带宽进行划分。
302、网络侧设备配置资源配置信息；
网络侧设备将可用带宽划分得到一个主子带和至少一个副子带后，配置资源配置信息，其中，资源配置信息至少包括主子带的信息，主子带的信息具体可包括以下信息中的至少一种：主子带资源在时域上与SFN起始位置或者DFN起始位置的偏移量、主子带上的资源周期、主子带上每个资源周期内包含的时域资源、主子带在频域的位置、主子带在频域上占用的资源大小。需要说明的是，确定主子带所需要的全部信息包括主子带资源在时域上与SFN起始位置或者DFN起始位置的偏移量、主子带上的资源周期、主子带上每个资源周期内包含的时域资源、主子带在频域的位置和主子带在频域上占用的资源大小，若主子带的信息只包括该全部信息中的部分信息，则可在预配置的信息中获得全部信息中的其他信息。可选的，资源配置信息中还可以包括副子带的信息，其中副子带的信息可以为副子带的具体信息或映射关系。当副子带的信息为副子带的具体信息时，包括以下信息中的至少一种：副子带的时频域资源位置、副子带在频域上占用资源的大小、信号在副子带上的发送周期等。
可以理解的是，资源配置信息除了包括主子带的信息外，还可以包括终端接收资源池 的信息(例如资源池的时频资源位置)、目标子带上资源可使用的时间段等。
本发明中主(primary)子带和副(secondary)子带是一种相对概念。Relay UE在主子带上发送消息的资源由网络侧设备例如eNB配置，RelayUE在副子带上发送消息所使用的资源与主子带上所使用的资源有一定关联关系。
当副子带的信息为映射关系时，该映射关系为主子带资源与对应的副子带资源之间的关系，如表1所列举的一种简单的映射关系，将主子带上资源的序号与相同序号的副子带关联，假设主子带包含6个PRB，每个时间间隔(本申请中，时间间隔指一个固定的时间单位。目前LTE标准中，时间间隔长度等于子帧的时间长度，即时间间隔可用子帧表示)上的两个PRB组成一个资源块得到3个资源块，将该3个资源块分别编号资源块1、资源块2和资源块3，对副子带也进行编号，分别编号为副子带1～副子带3，将主子带上资源块1～资源块3分别与副子带1～副子带3关联，即如果配置第一终端在主子带资源块1发送信号，则第一终端后续发送信号在副子带1上的资源上发送，可以理解为副子带上的资源根据主子带上所配置的资源位置来决定。
表1
主子带上资源的序号 副子带序号
资源块1 副子带1
资源块2 副子带2
资源块3 副子带3
另外，网络侧设备在配置映射关系时，还可以采用动态配置的方式，即该映射关系可以是变化的，故映射关系的配置方式具体此处不做限定。
可以理解的是，表1的示例是将主子带上资源块与副子带直接映射，即一个主子带上的资源块映射到一个副子带相应的资源块集合；其他映射关系还可以是主子带上资源与副子带上资源映射，例如主子带上的一个或多个资源块映射到一个副子带上不同的资源块集合上，也可以是主子带上的N个资源块映射到M个副子带上的L个不同的资源块集合上。另外，主子带上不同时间间隔的资源块可以映射到副子带上不同的时域偏移或者频域偏移，即映射关系还可以为主子带资源与副子带上映射的资源在时域上的偏移量，即可以通过已知的主子带资源的位置，再根据偏移量，获得副子带上映射的资源的位置，同理映射关系也可以为主子带资源与副子带上映射的资源在频域上的偏移量，故映射关系的内容具体此处不做限定。
需要说明的是，本申请实施例中，网络侧设备通过步骤301和步骤302划分可用带宽为若干个子带，且配置资源配置信息，在实际应用中，可用带宽的划分和资源配置信息都可以预配置，具体此处不做限定。其中本申请实施例中，预配置的信息为根据协议约定的信息。
303、网络侧设备通过广播信道发送资源配置信息；
网络侧设备通过广播信道发送资源配置信息，以使得第一终端和网络侧设备覆盖范围内的第二终端均获得该资源配置信息。其中，该资源配置信息至少包括主子带的信息，通过该主子带的信息可确定主子带。
可选的，当该资源配置信息还包括副子带的信息时，副子带的信息可以为副子带的具体信息或者主子带资源与对应的副子带资源之间的映射关系。当副子带的信息为映射关系时，网络侧设备可动态配置该映射关系，例如网络侧设备每隔预置个数的主子带上资源的周期或者预置时间或者满足预设条件(如资源利用率信息)，便通过广播信道发送新的映射关系，使得第一终端和网络侧设备覆盖范围内的第二终端获得该新的映射关系。
304、网络侧设备接收第一终端发送的资源请求；
网络侧设备接收到第一终端发送的资源请求，该资源请求用于请求网络侧设备在可用带宽上为该第一终端配置发送第一消息所使用的资源，以让第一终端通过该资源向第二终端发送第一消息。
可以理解的是，303和304没有严格的先后顺序，由网络侧设备决定。
305、网络侧设备向第一终端发送第一信令；
网络侧设备接收到第一种端发送的资源请求后，向第一终端发送第一信令，其中该第一信令用于向第一终端配置第二目标资源，其中第二目标资源用于第一终端在主子带上发送第一消息。
可选的，当网络侧设备发送的资源配置信息中仅包括主子带的信息时，第一信令还可用于向第一终端配置目标副子带上的第一目标资源，该第一目标资源用于第一终端在目标副子带上发送第一消息，其中，该第一目标资源由基站为第一终端配置。
需要说明的是，网络侧设备通过第一信令向第一终端配置第一目标资源，该配置的方式可为动态配置，例如网络侧设备每隔预置个数的主子带上资源的周期，便向第一终端周期性再次发送第一信令，该第一信令用于向第一终端配置新的第一目标资源。
306、第一终端获取资源配置信息；
由于第一终端需要在目标子带上发送第一消息，故第一终端要获取目标子带的信息。当目标子带为主子带时，第一终端接收网络侧设备通过广播信道发送的主子带的信息，或者第一终端在预配置的信息中获得主子带的信息，故第一终端获得主子带的信息的方式具体此处不做限定。
可选的，当目标子带还包括目标副子带时，对应的资源配置信息还包括目标副子带的信息。其中第一终端获取目标副子带的信息的途径有多种，包括：
1、第一终端在预配置信息中获取目标副子带的信息，该目标副子带的信息可以为目标副子带的具体信息或者映射关系；2、第一终端接收到网络侧设备通过广播信道发送的目标副子带的信息，该目标副子带的信息可以为副子带的具体信息或者映射关系，需要说明的是，当映射关系由网络侧设备配置时，该映射关系可以是不变的或者是动态变化的，具体此处不做限定。故实际应用中，第一终端获取目标副子带的信息的方式具体此处不做限定。
其中，在本申请实施例中，第一终端可以为无线终端、智能终端、支持sidelink的其他终端、中继终端等，具体此处不做限定。
307、第一终端确定目标资源；
第一终端获取到资源配置信息后，确定目标资源进而通过该目标资源向第二终端发送第一消息。第一终端接收到网络侧设备发送的第一信令后，该第一信令至少用于向第一终 端配置主子带上的第二目标资源，该第二目标资源用于第一终端在主子带上发送第一消息。
可选的，若第一终端还在对应的目标副子带上发送第一消息时，目标资源还包括第一终端在目标副子带上发送第一消息所使用的资源即第一目标资源，故第一终端还需确定第一目标资源。由于第一终端获取得到的资源配置信息的方式和内容有多种，以及第一信令所包含的内容也有多种，对应的，第一终端确定第一目标资源的方式也有多种，包括：
①第一终端通过第一信令和映射关系确定第一目标资源；
由于第一信令用于向第一终端配置主子带上的第二目标资源，故通过该第一信令，第一终端确定主子带上的第二目标资源，当第一终端获得的资源配置信息中包括映射关系时，第一终端在该映射关系中找出与第二目标资源对应的第一目标资源，其中该映射关系为预配置的或者由网络侧设备通过广播信道发送。
②第一终端通过第一信令确定第一目标资源。
当第一信令还用于向第一终端配置目标副子带上的第一目标资源时，则第一终端可直接从第一信令中获得第一目标资源，其中，该第一目标资源由网络侧设备配置。
可以理解的是，当第一信令还用于向第一终端配置目标副子带上的第一目标资源时，由于该第一信令由网络侧设备向第一终端发送而未向第二终端发送，第二终端并不知道该第一目标资源，为了让第二终端接收到第一终端利用该第一目标资源发送的第一消息，第一终端在主子带上发送的第一消息中携带指示信息，该指示信息用于向第二终端指示该第一目标资源。
故第一终端获得目标副子带上发送第一消息所使用的资源的方式具体此处不做限定。
308、第一终端在目标子带上通过目标资源发送第一消息；
第一终端确定了目标资源后，在确定的目标资源上发送第一消息，其中，目标子带为主子带时，目标资源为第二目标资源，该第二目标资源为第一终端在主子带上发送第一消息所使用的资源。
当目标子带还包括目标副子带时，则目标资源还包括第一终端在目标副子带上发送第一消息所使用的资源，即第一目标资源。因此第一终端在主子带上通过第二目标资源发送第一消息，在目标副子带上通过第一目标资源发送第一消息。如图4所示，为第一终端在主子带和副子带上周期性发送第一消息的示意图，图中，可用带宽被均等划分成1个主子带和4个副子带，有三个第一终端分别为Relay UE1、Relay UE2和Relay UE3，都向网络侧设备发送资源请求，该资源请求用于请求网络侧设备配置发送第一消息所使用的资源。网络侧设备为这三个第一终端在主子带的某个子帧上分配了三个正交的资源块，分别编号为资源块1～资源块3，各第一终端在主子带上周期性发送第一消息，主子带上的资源块与副子带的序号存在映射关系，因此各第一终端在主子带上发送了第一消息后，分别转到对应的副子带上发送，如RelayUE1在主子带资源块1上发送了第一消息后，继续在副子带1指定的位置再周期发送一段时间，然后再重复上面的过程。
309、第二终端获取资源配置信息；
由于第二终端需要在目标子带上接收第一终端发送的第一消息，故第二终端要获取目标子带的信息。当目标子带为主子带时，第二终端接收网络侧设备通过广播信道发送的主 子带的信息，或者第二终端在预配置的信息中获得主子带的信息，第二终端获得主子带的信息的方式具体此处不做限定。
可选的，当目标子带还包括目标副子带时，对应的资源配置信息还包括目标副子带的信息。其中第二终端获取目标副子带的信息的途径有多种，包括：
1、第二终端在预配置信息中获取目标副子带的信息，该目标副子带的信息可以为目标副子带的具体信息或者映射关系；2、第二终端接收到网络侧设备通过广播信道发送的目标副子带的信息，该目标副子带的信息可以为副子带的具体信息或者映射关系，需要说明的是，当映射关系由网络侧设备配置时，该映射关系可以是不变的或者是动态变化的，具体此处不做限定。故实际应用中，第二终端获取目标副子带的信息的方式具体此处不做限定。
可以理解的是，本申请实施例中，当第二终端在网络侧设备覆盖范围外时，第二终端不能直接接收网络侧设备发送的消息，故当配置信息由网络侧设备通过广播信道发送时，对第二终端而言，该配置信息均由预配置信息替代。
其中，在本申请实施例中，第二终端可以为可穿戴设备、IoT设备、其他支持sidelink的终端或者远端终端等，具体此处不做限定。
310、第二终端确定主子带；
第二终端获取到资源配置信息后，根据资源配置信息中包括的主子带的信息确定主子带。第二终端可通过主子带在频域的位置确定主子带。需要说明的是，实际应用中，第二终端确定主子带的方式有多种，例如若资源配置信息中还包括主子带的标识时，则第二终端通过该主子带的标识找出主子带，或者资源配置消息中还包括主子带在频域上与固定频域位置在频域上的偏移量，则第二终端根据该偏移量确定主子带。故第二终端确定主子带的方式具体此处不做限定。
311、第二终端根据资源配置信息在主子带上接收第一终端发送的第一消息；
第二终端确定主子带后，第二终端在主子带上可以通过资源配置信息中主子带资源在时域上与SFN或DFN起始位置的偏移量以及主子带上资源的周期确定了主子带资源的位置信息，该主子带资源为第一终端在主子带上所使用的资源，故第二终端通过该主子带资源的位置信息在主子带上对应位置接收第一终端发送的第一消息，需要说明的是，该第一终端可以为多个终端。
312、第二终端确定目标终端；
第二终端在主子带上接收到第一终端发送的第一消息后，对接收到的第一消息进行解调，获得第一消息中携带的第一终端的信息，例如公共陆地移动网络(Public Land Mobile Network，PLMN)的标识、第一终端的标识等信息，以及第一消息的接收信号强度，该第二终端选择满足预设条件的第一终端作为目标终端。例如，第二终端选择接收信号强度最大的第一消息所对应的第一终端为目标终端。
需要说明的是，实际应用中，第二终端确定目标终端的方式有多种，例如，第二终端获取第一终端的综合信道质量，且综合信道质量为第一终端与网络侧设备用于通信的信道的质量和第一终端与第二终端用户通信的信道的质量中信道质量较低的信道质量，第二终端确定第一终端中综合信道质量最高的终端为目标终端。再例如，第二终端可以选择第一 消息的接收信号强度超过预设阈值且曾经与第二终端关联过的第一终端作为目标终端。故第二终端确定目标终端的方式具体此处不做限定。
313、第二终端确定目标副子带；
第二终端确定了目标终端后，需确定与该目标终端对应的目标副子带，以在目标副子带上接收第一终端发送的第一消息。需要说明的是，实际应用中，第二终端确定目标副子带的方式有多种，包括：
①第二终端通过主子带资源与对应的副子带资源之间的映射关系，和主子带的信息确定目标副子带；
第二终端获得资源配置信息后，若该资源配置信息包括该映射关系和主子带的信息，其中该映射关系和主子带的信息均可通过网络侧设备通过广播信道发送得到或者在预配置的信息中获得，则第二终端在该映射关系中找出
②第二终端根据指示信息确定目标副子带；
若第二终端在主子带上接收到的第一消息中携带有指示信息，且该指示信息用于指示目标副子带上的目标资源，该目标副子带上的目标资源为第一终端在目标副子带上发送第一消息的资源，且该指示信息由第一终端在该第一消息中添加，故第二终端找到该目标副子带上的目标资源对应的子带为目标副子带。
③第二终端根据目标副子带的具体信息确定目标副子带。
当第二终端获得的资源配置信息中包括目标副子带的具体信息时，其中，该目标副子带信息为预配置的或者由网络侧设备通过广播信道发送，目标副子带的具体信息中至少包括以下一种：副子带的时频资源位置、占用的资源大小或信号在副子带上的发送周期，第二终端通过该目标副子带的具体信息确定目标副子带。
314、第二终端在目标副子带接收第一消息；
第二终端确定目标副子带后，第二终端在目标副子带上根据第一目标资源的位置，对应接收到第一终端发送的第一消息，以通过该第一消息测量信号的质量，其中第一目标资源为第一终端在目标副子带上发送第一消息所使用的资源，且该第一目标资源的位置可以为预置的，或者由网络侧设备通过广播信道发送获得，还可以通过第一终端在主子带上发送的第一信息所携带的指示信息来确定，其中该指示信息用于指示第一目标资源的位置，故第一目标资源的位置的获得方式具体此处不做限定。
315、第二终端根据在副子带上接收到的第一消息测量信号质量；
第二终端检测副子带上接收到的第一消息，获得该第一消息的实际信号质量参数，例如，该信号质量参数为信号接收功率，将该实际信号接收功率与参考信号接收功率比较，来测量第一终端的信号质量。
实际应用中，第二终端还可以通过接收到的第一信息的过程，如根据误码率或信噪比等是否满足参考值，来测量信号质量。故测量方式具体此处不做限定。
316、第二终端在主子带上继续接收第一消息。
若目标终端的信号强度低于预置门限值时，第二终端从目标副子带返回主子带上继续接收第一消息，并对接收到的第一消息进行解调来重新确定新的目标终端，直到确定该新 的目标终端的信号强度大于预置门限值，则跳转到新的目标终端对应的副子带上接收第一终端发送的第一消息。
需要说明的是，实际应用中，触发第二终端返回主子带的触发方式有多种，还包括第二终端获取周期指令，该周期指令可以预先配置或者由网络侧设备通过广播信道发送，其中该周期指令用于指示第二终端在主子带副子带之间进行周期性切换，第二终端通过该周期指令在主子带上继续接收第一消息，并对接收到的第一消息进行解调，再从中选择合适的(比如信号强度最强的)第一消息所对应的第一终端为新的目标终端，进而跳转到新的目标终端对应的副子带上继续接收第一消息，依此周期重复。或者设置定时器，当定时器指示到达设定的时长时，第二终端在主子带上继续接收第一消息。故第二终端在主子带的触发方式具体此处不做限定。
本申请实施例中，网络侧设备将第一终端与第二终端之间进行通信的所使用的可用带宽划分，得到主子带和至少一个副子带，第一终端把第一消息分别放到主子带和副子带上发送，可以减小主子带的负荷，同时，也减小了第一终端之间的带内泄露干扰。
如无特别指出，本实施例中各个步骤之间没有严格的先后顺序，可以由各步骤的实施主体和/或其他实施主体发送的信号触发等决定。
上述图3所示的实施例中将第一终端与第二终端之间用于通信的可用带宽划分为一个主子带和至少一个副子带，实际应用中，还可将该可用带宽划分为多个主子带和多个副子带，具体如图5所示，本申请实施例中资源配置方法和终端通信方法的另一实施例包括：
501、网络侧设备将可用带宽划分成多个主子带和多个副子带；
在D2D技术中，存在多个终端在可用宽带上选择资源发送第一消息的情况，其中该可用宽带为用于终端之间进行通信的频带。网络侧设备将该可用带宽进行划分得到第一主子带、与该第一主子带关联的至少一个第一副子带、第二主子带和与第二主子带关联的至少一个第二副子带，其中该第一主子带的带宽与至少一个第一副子带的带宽相同，第二主子带的带宽与至少一个第二副子带的带宽相同，第一主子带的带宽与第二主子带的带宽不同，即相同带宽的主子带与副子带之间存在映射关系，如图6所示为不同带宽的子带在可用带宽上的划分方式，其中不同带宽的子带包括6PRB带宽的子带和1PRB带宽的子带。需要说明的是，对应相同带宽的子带在划分方式上是可以在连续的频域资源位置上，也可以在不连续的频域资源位置上，具体此处不做限定。
另外，实际应用中，不同带宽的子带可以都在时域上划分，或都在频域上划分，不同带宽的子带也可以采用时分复用的方式进行划分，如图7所示，当6PRB带宽的子带和1PRB带宽的子带在可用带宽上共存时，6PRB带宽的子带的划分可以为在一定频带内在时域上进行划分，1PRB带宽的子带的划分可以为在一定时间间隔内在频域上进行划分，故具体划分方式此处不做限定。
502、网络侧设备配置资源配置信息；
网络侧设备将可用带宽划分后，配置资源配置信息，其中，资源配置信息至少包括各主子带的信息，各主子带的信息具体可包括以下信息中的至少一种：主子带资源在时域上与SFN起始位置或者DFN起始位置的偏移量、主子带上每个资源周期内包含的时域资源、 主子带上资源的周期、主子带在频域的位置、主子带在频域上占用的资源大小。
可选的，资源配置信息中还可以包括各副子带的信息，其中，各副子带的信息可以包括以下信息中的至少一种：副子带的时频域资源位置、副子带在频域上占用资源的大小、主子带上资源的周期、信号在副子带上的发送周期等。
当各副子带的信息为映射关系时，本实施例中存在至少两个映射关系，即第一主子带资源与对应的第一副子带资源之间的关系，以及第二主子带资源与对应的第二副子带资源之间的关系，由网络侧设备通过广播信道发送该两个映射关系。
可以理解的是，资源配置信息除了包括主子带的信息外，还可以包括终端接收资源池的信息(例如资源池的时频资源位置)、目标子带上资源可使用的时间段等，具体此处不做限定。

本申请实施例中，将可用带宽划分得到的子带中包括多个主子带，考虑到了实际应用中需要在同一个频带内支持多个工作带宽不同的设备的情况，增加了本申请实施例的实现方式。
如无特别指出，本实施例中各个步骤之间没有严格的先后顺序，可以由各步骤的实施主体和/或其他实施主体发送的信号触发等决定。
上述图3和图5示出了将可用带宽划分得到的子带中包括至少一个主子带和至少一个副子带的情况，下面图9再对将可用带宽划分得到多个对等子带的情况进行说明。

902、网络侧设备配置资源配置信息；
网络侧设备将可用带宽均等划分成若干个对等子带后，网络侧设备配置资源配置信息，其中该资源配置信息包括该若干个对等子带的信息。其中，该对等子带的信息至少包括以下信息中的一种：子带划分方式、时域上的资源分配的位置和周期，其中，第一消息为广播消息。可选的，子带的信息中还可以包括第一消息的发送方式，且该第一消息的发送方式可以有多种，包括全宽带发送、梳状发送方式和跳变发送方式，具体此处不做限定。其中，全宽带方式用于指示第一终端使用一个或多个对等子带在一个时间间隔内的全部资源进行发送，梳状发送方式用于指示第一终端使用一个或多个对等子带在一个时间间隔内相同资源位置的资源进行发送，跳变发送方式用于指示第一终端使用一个或多个对等子带在不同时间间隔内不同资源位置的资源进行发送。
另外，对等子带的信息中还可包括第二终端所支持的带宽和对应的第一消息的发送周期之间的关系，该关系可用于针对所支持的带宽不同的第二终端，第一终端发送第一消息时采用不同的发送周期，例如当第二终端所支持的带宽较窄如IoT设备时，第一终端发送 采用较长的发送周期。
可以理解的是，资源配置信息除了包括主子带的信息外，还可以包括终端接收资源池的信息(例如资源池的时频资源位置)、目标子带上资源可使用的时间段等，具体此处不做限定。
需要说明的是，本申请实施例中，网络侧设备通过步骤901和步骤902划分可用带宽为若干个对等子带，且配置资源配置信息，在实际应用中，可用带宽的划分和资源配置信息都可以预配置，故具体此处不做限定。
903、网络侧设备通过广播信道发送资源配置信息；
网络侧设备配置资源配置信息后，网络侧设备通过广播信道发送资源配置信息，以使得第一终端和网络侧设备覆盖范围内的第二终端均获得该资源配置信息，其中该资源配置信息包括一个或多个对等子带的信息，该对等子带的信息用于确定该对等子带。
904、网络侧设备接收第一终端发送的资源请求；
本申请实施例中，步骤904与图3所示的步骤304类似，此处不再赘述。
905、网络侧设备向第一终端发送第一信令；
网络侧设备将资源配置信息通过广播信道发送后，向第一终端发送第一信令，该第一信令用于向第一终端配置一个或多个对等子带上的资源，其中该第一信令中至少包括资源位置和传输次数，需要说明的是，网络侧设备通过第一信令向第一终端配置一个或多个对等子带上的资源，该配置的方式可为动态配置或者固定采用一种配置方式，具体此处不做限定。
906、第一终端获取资源配置信息；
第一终端需要利用一个或多个对等子带上的资源发送第一消息，故第一终端需获取到该一个或多个对等子带的信息。需要说明的是，第一终端获取资源配置信息的方式有多种，包括从预配置的信息中获取，或者接收网络侧设备发通过广播信道发送的资源配置信息，故第一终端获取资源配置信息的方式具体此处不做限定。
907、第一终端在一个或多个对等子带上通过目标资源发送第一消息；
第一终端接收到网络设备发送的第一信令后，该第一信令用于向第一终端配置一个或多个对等子带上的资源。第一终端根据该第一信令和资源配置信息确定各对等子带上的目标资源，第一终端在一个或多个对等子带上通过各对等子带上的目标资源发送第一消息。
可选的，第一终端获得的资源配置信息中还可包括第一消息的发送方式，其中，第一终端获得该第一消息的方式有多种，例如可以获取预配置的第一消息的发送方式，或者由第一终端从对等子带的信息中提取第一消息的发送方式，故具体获得方式此处不做限定。当第一终端获得的资源配置信息中所包含的第一消息的发送方式为全宽带方式，则第一终端使用一个或多个对等子带在一个时间间隔内的全部资源发送第一消息，如图10所示，为第一终端通过全宽带方式发送第一消息的场景，其中，可用带宽被分为6个对等子带，则网络侧设备为每个第一终端分配一个时间间隔，其中编号相同的资源块对应同一个第一终端，使得第一终端在一个时间间隔上的整个频带发送第一消息，即第一终端使用了一个或多个对等子带在一个时间间隔内的全部资源发送第一消息。
当第一终端获得的资源配置信息中所包含的第一消息的发送方式为梳状发送方式时，则第一终端使用一个或多个对等子带在一个时间间隔内相同资源位置的资源发送第一消息，如图11所示，为第一终端通过梳状发送方式发送第一消息的场景，其中，可用频带被分为6个对等子带，网络侧设备在不同时间间隔上为第一终端分配发送资源，其中，相同编号的资源块对应同一个第一终端，可以看出，在一个时间间隔内，相同编号的资源块位于各对等子带的相同资源位置，即第一终端使用了一个或多个对等子带在一个时间间隔内相同资源位置的资源发送第一消息。
当第一终端获得的资源配置信息中所包含的第一消息的发送方式为跳变发送方式时，则第一终端使用一个或多个对等子带在不同时间间隔内不同资源位置的资源发送第一消息，如图12所示，为第一终端通过跳变发送方式发送第一消息的场景，其中，可用频带被分为6个对等子带，网络侧设备可以配置或预配置一种时频跳变规则，使得第一终端在全部对等子带上跳变发送第一消息，图12中，6个第一终端在6个对等子带和6个时间间隔上按照一定的跳变规则跳变，即一个或多个对等子带上对应相同的第一终端的匹配块的时域位置和频域位置均不相同，即第一终端用一个或多个对等子带在不同时间间隔内不同资源位置的资源发送第一消息。进一步地，可以将第一终端在一个时间间隔内发送第一消息占用的资源块数设为1，如13所示，可用频带被分为3个对等子带，在一个时间间隔内，每个对等子带上第一终端对应的资源块的时域和频域位置也均不相同，故第一终端通过该一个或多个对等子带在不同时间间隔内不同资源位置的资源发送第一消息。
908、第二终端获取资源配置信息；
第二终端需要接收第一终端在一个或多个对等子带上的资源上发送的第一消息，故第二终端需获取得到一个或多个对等子带的信息。需要说明的是，第二终端获取资源配置信息的方式有多种，包括从预配置的信息中获取，或者接收网络侧设备发通过广播信道发送的资源配置信息，故第一终端获取资源配置信息的方式具体此处不做限定。
909、第二终端根据资源配置信息在目标子带上接收第一终端发送的第一消息。
第二终端获取到资源配置信息后，第二终端在所支持的带宽中选择目标子带，并根据资源配置信息中该目标子带的信息在目标子带上接收第一终端发送的第一消息。
本申请实施例中，将可用资源均等划分为若干个对等子带，并提供了多种发送方式，使得第二终端在任一对等子带上都能接收到第一消息，使得工作频带窄的第二终端不需要切换工作频带，减少了第二终端的功耗。
如无特别指出，本实施例中各个步骤之间没有严格的先后顺序，可以由各步骤的实施主体和/或其他实施主体发送的信号触发等决定。
