并且，通信系统中设备之间的通信可以根据任意阶段的通信协议进行，例如可以包括但不限于如下通信协议：1G(generation)、2G、2.5G、2.75G、3G、4G、4.5G以及未来的5G、新无线(NR，New Radio)等等，和/或其他目前已知或未来将被开发的通信协议。
在本发明实施例中，术语“网络设备”例如是指通信系统中将终端设备接入通信网络并为该终端设备提供服务的设备。网络设备可以包括但不限于如下设备：基站(BS，Base Station)、接入点(AP、Access Point)、发送接收点(TRP，Transmission Reception Point)、广播发射机、移动管理实体(MME、Mobile Management Entity)、网关、服务器、无线网络控制器(RNC，Radio Network Controller)、基站控制器(BSC，Base Station Controller)等等。
其中，基站可以包括但不限于：节点B(NodeB或NB)、演进节点B(eNodeB或eNB)以及5G基站(gNB)，等等，此外还可包括远端无线头(RRH，Remote Radio Head)、远端无线单元(RRU，Remote Radio Unit)、中继(relay)或者低功率节点(例如femto、pico等等)。并且术语“基站”可以包括它们的一些或所有功能，每个基站可以对特定的地理区域提供通信覆盖。术语“小区”可以指的是基站和/或其覆盖区域，这取决于使用该术语的上下文。

以下通过示例对本发明实施例的场景进行说明，但本发明不限于此。
图1是本发明实施例的通信系统的一示意图，示意性说明了以终端设备和网络设备为例的情况，如图1所示，通信系统100可以包括网络设备101和终端设备102。为简单起见，图1仅以一个终端设备和一个网络设备为例进行说明，但本发明实施例不限于此。
在本发明实施例中，网络设备101和终端设备102之间可以进行现有的业务或者未来可实施的业务。例如，这些业务可以包括但不限于：增强的移动宽带(eMBB，enhanced Mobile Broadband)、大规模机器类型通信(mMTC，massive Machine Type Communication)和高可靠低时延通信(URLLC，Ultra-Reliable and Low-Latency Communication)，等等。以下以新类型载波为NR载波为例说明，但本实施例并不以此作为限制。
例如，针对NR载波和LTE载波共存的情况，大致有如下部署方法：
例如，由于NR载波的范围较大，可以在其中预留一部分频域资源用作一个虚拟的LTE载波，MTC设备收发数据占用的PRB被限制在此虚拟LTE载波内；MTC设备可以使用6个PRB加上虚拟的LTE载波的中心直流DC子载波(即6*12+1＝73个子载波)。
图2是将NR载波虚拟出的LTE载波中的一部分作为MTC载波的示意图，如图2所示，在NR载波中可以虚拟出LTE载波，并且MTC载波(即MTC设备占用的PRB)可以位于该虚拟LTE载波中。对于LTE下行载波，其中心频点处具有DC子载波，并且该DC子载波不能被使用，需要进行预留，在进行初始同步时，终端设备需要按照73个子载波进行同步信号检测。图3是NR载波和LTE载波共存时PRB位置示意图，如图3所示，由于LTE载波中心空出了一个DC子载波，将使得PRB的位置产生偏移，对于MTC设备和NR设备来说，产生了对PRB的位置的理解分歧(例如该偏移导致在LTE载波上一个PRB的频域位置相当于占用了NR载波上两个PRB的部分频域位置)，在资源调度时，会导致部分空闲资源不可用。
在本实施例中，网络设备显示或隐式的指示该资源栅格偏移信息，未来系统(例如NR)终端设备可以根据网络设备发送的资源栅格偏移信息或在第一类型载波上配置的虚拟第二类型载波的信息，确定可供调度的资源的频域位置，使得MTC设备能 够和未来系统(例如NR)设备对可供调度的资源的频域位置有相同的理解，从而使得MTC设备能够和未来系统(例如NR)设备在新类型载波上进行良好共存，并正常工作。
以下将以NR系统为例，对本发明实施例进行说明；但本发明不限于此，还可以适用于任何存在类似问题的系统或场景中。此外，本申请以NR设备为例进行说明，但本发明不限于此，例如还可以是其他类型的终端设备。
下面结合附图对本发明实施例进行说明。
实施例1
图4是本实施例1的资源指示方法流程图，应用于网络设备侧。如图4所示，该方法包括：
步骤401，网络设备向终端设备发送资源指示信息，该资源指示信息用于指示第一类型载波上部分带宽的资源栅格偏移信息。
在本实施例中，该终端设备是工作在第一类型载波上的终端设备，例如，该第一类型载波可以是未来无线通信系统使用的新类型载波，例如NR载波，载波带宽可能达到400MHz，以上仅为示例说明，本实施例并不以此作为限制。
在本实施例中，该部分带宽表示在该第一类型载波上的网络设备为终端设备配置的部分带宽(BWP)，该网络设备和终端设备可以在该部分带宽上所分配的资源中进行数据的收发，其中，该部分带宽可以是上行BWP，终端设备可以在该上行BWP上所分配的资源上向网络设备发送数据，或者，该部分带宽也可以是下行BWP，终端设备可以在该下行BWP上所分配的资源上接收所述网络设备发送的数据。
在本实施例中，该网络设备可以为该终端设备预先配置并发送该部分带宽的相关信息BWP-DownlinkCommon，该相关信息可以包括BWP的位置信息、标识信息等，例如该位置信息包括BWP的中心频点(或起始位置)、带宽、子载波间隔等信息，此处不再一一举例。
在本实施例中，该部分带宽上对应预定时域位置传输的信号可以用资源栅格来表示，该资源栅格包括第一数量个子载波和第二数量个符号，该第一数量的大小根据部分带宽的频带宽度确定，该第二数量的大小可以根据标准预定义，图5是该资源栅格结构示意图，如图5所示，资源栅格由预定数量的资源粒子(RE)组成(频域上一 个子载波和时域上一个符号构成一个RE)，频域上RE的数量等于该第一数量，时域上RE的数量等于该第二数量。
在本实施例中，资源指示信息用于指示第一类型载波上部分带宽的资源栅格偏移信息，终端设备在确定可供收发数据的资源时，根据该资源指示信息即可确定资源栅格进行了频域偏移。
在本实施例中，该资源栅格偏移信息包括频域偏移量，该频域偏移量包括第一预定数量个子载波，该第一预定数量为整数，其中，该第一预定数量可以用第三数量个比特表示；例如，在第三数量等于1时，在比特值为0时，表示偏移量为0(即不发生偏移)，在比特值为1时，表示偏移量是1个子载波，该偏移的方向可以是物理资源块索引增大的方向，如图5所示，该资源栅格在频域上向物理资源块索引增大的方向偏移1个子载波(虚线表示)；例如，在第三数量大于1(例如2)时，在比特值为00时，表示偏移量为0(即不发生偏移)，在比特值为“11”时，表示偏移量是3个子载波，该偏移的方向可以是物理资源块索引增大的方向，以上仅以第三数量为2举例说明，但本实施例并不以此作为限制，例如，在该第三数量等于4时，即可以用于指示偏移量为0～11个子载波。
在本实施例中，该资源指示信息可以由无线资源控制(RRC)层信令或物理层信令承载，例如，可以在上述网络设备RRC层配置的相关信息BWP-DownlinkCommon中新建一个信息元(IE)携带该资源指示信息，但本实施例并不以此作为限制，例如还可以在其他信令，例如物理下行控制信道(PDCCH)信令中携带该资源指示信息。
在本实施例中，为了更加灵活的指示该资源栅格偏移信息，该方法还可以包括：
步骤402(可选)，该网络设备向该终端设备发送偏移基准位置指示信息，在该部分带宽中，频域上的位置大于等于该偏移基准位置的资源块与频域上的位置小于该偏移基准位置的资源块的频域偏移量不同；或者频域上的位置大于该偏移基准位置的资源块与频域上的位置小于等于该偏移基准位置的资源块的频域偏移量不同。
在本实施例中，该偏移基准位置指示信息为物理资源块索引index0，该index0可以是0～274，可以利用9比特表示该偏移基准位置指示信息；其中，该偏移基准位置根据第一类型载波上虚拟的第二类型载波的直流子载波的位置确定；即在该部分带宽中，PRB索引大于等于index0的资源块与PRB索引小于index0的资源块的频域偏移量不同；或者PRB索引大于index0的资源块与PRB索引小于等于index0的资源 块的频域偏移量不同。
在本实施例中，为了在第一类型载波上支持MTC设备收发数据，可以在第一类型载波中预留一部分频域资源用作一个虚拟的第二类型载波，MTC设备收发数据占用的PRB被限制在此虚拟的第二类型载波内，该第二类型载波与该第一类型载波的工作频段不同，例如该第二类型载波为LTE载波，具体工作频段可以参考现有技术，如图2所示，该第二类型载波的中心频点为直流子载波，可以将该直流子载波所在的PRB的索引作为该index0。
在本实施例中，终端设备可以结合该偏移基准位置指示信息以及资源指示信息确定资源栅格的偏移量，其具体实施方式将在如下实施例2中说明。
在本实施例中，该方法还包括：(未图示)
该网络设备向终端设备发送用于指示该资源栅格偏移信息生效的指示信息，该指示信息是机器类型通讯终端设备的可用子帧(例如子帧号)，该指示信息可以通过RRC信令或物理层信令承载，终端设备在接收到该指示信息后，可以确定该资源栅格偏移信息何时生效何时无效，其具体确定方式将在如下实施例2中说明。
通过上述实施例可知，未来系统(例如NR)终端设备可以根据网络设备发送的资源栅格偏移信息，确定可供调度的资源的频域位置，使得MTC设备能够和未来系统(例如NR)设备对可供调度的资源的频域位置有相同的理解，从而使得MTC设备能够和未来系统(例如NR)设备在新类型载波上进行良好共存，并正常工作。
实施例2
图6是本实施例2的资源指示方法流程图，应用于终端设备侧。如图5所示，该方法包括：
步骤601，终端设备接收网络设备发送的资源指示信息，该资源指示信息用于指示第一类型载波上部分带宽的资源栅格偏移信息。
在本实施例中，该资源指示信息的具体实施方式可以参考实施例1，步骤601的具体实施方式可以参考步骤401，此处不再赘述。
在本实施例中，该方法还可以包括：
步骤603，该终端设备根据该资源栅格偏移信息确定该部分带宽的资源栅格位置。
在本实施例中，终端设备可以根据该部分带宽的位置信息结合该资源栅格偏移信息确定该部分带宽的资源栅格位置，其中，该部分带宽的位置信息可以由网络设备配置并发送给该终端设备，例如该位置信息包括：BWP的中心频点(或起始位置)、带宽、子载波间隔等信息，终端设备根据该位置信息即可以确定该BWP的资源栅格的初始位置(其具体实施方式可以参考现有技术，例如根据BWP-DownlinkCommon中的locationAndBandwidth指示的起始位置和频带宽度以及subcarrierSpacing指示的子载波间隔确定该初始位置)，以该初始位置作为基准位置，在频域上加上资源栅格偏移信息包括的频域偏移量后，即可以确定偏移后的该BWP的资源栅格位置，即可供调度的资源的频域位置。
在本实施例中，可选的，为了更加灵活的指示该资源栅格偏移信息，该方法还可以包括：
步骤602(可选)，终端设备接收网络设备发送的偏移基准位置指示信息，在该BWP中，频域上的位置大于等于该偏移基准位置的资源块与频域上的位置小于该偏移基准位置的资源块的频域偏移量不同；或者频域上的位置大于该偏移基准位置的资源块与频域上的位置小于等于该偏移基准位置的资源块的频域偏移量不同。
在本实施例中，该偏移基准位置指示信息为物理资源块索引index0，其中，该偏移基准位置根据第一类型载波上虚拟的第二类型载波的直流子载波的位置确定该部分带宽的资源栅格位置。
在步骤603中，终端设备可以结合该偏移基准位置指示信息和该资源栅格偏移信息确定该部分带宽的资源栅格的偏移量，根据该偏移量和该部分带宽的位置信息，获得可供调度的资源的频域位置。
图7A和图7B是本实施例中直流子载波位置示意图，以下结合图7A和7B说明如何确定该偏移量。
如图7A所示，该直流子载波位于一个物理资源块内(频域位置为该物理资源块内子载波索引号最大)，将该包含直流子载波的物理资源块的索引index0作为该偏移基准位置指示信息，在该BWP中，频域上的位置大于该偏移基准位置的资源块与频域上的位置小于等于该偏移基准位置的资源块的频域偏移量不同；频域上的位置大于该偏移基准位置的资源块的偏移量等于资源栅格偏移信息指示的第一预定数量个子载波，频域上的位置小于等于该偏移基准位置的资源块的偏移量等于资源栅格偏移信 息指示的第一预定数量减1个子载波；例如，该资源栅格偏移信息包含的频域偏移为N个子载波，即频域上的位置大于该偏移基准位置的资源块的偏移量等于N个子载波，即频域上的位置小于等于该偏移基准位置的资源块的偏移量等于N-1个子载波。
如图7B所示，该直流子载波位于一个物理资源块内(频域位置为该物理资源块内子载波索引号非最大)，将该包含直流子载波的物理资源块的索引index0作为该偏移基准位置指示信息，在该BWP中，频域上的位置大于等于该偏移基准位置的资源块与频域上的位置小于该偏移基准位置的资源块的频域偏移量不同；频域上的位置大于等于该偏移基准位置的资源块的偏移量等于资源栅格偏移信息指示的第一预定数量个子载波，频域上的位置小于该偏移基准位置的资源块的偏移量等于资源栅格偏移信息指示的第一预定数量减1个子载波；例如，该资源栅格偏移信息包含的频域偏移为N个子载波，即频域上的位置大于等于该偏移基准位置的资源块的偏移量等于N个子载波，即频域上的位置小于该偏移基准位置的资源块的偏移量等于N-1个子载波。
在本实施例中，该方法还可以包括：(可选，未图示)该终端设备接收该网络设备发送的用于指示该资源栅格偏移信息生效的指示信息，该指示信息是机器类型通讯终端设备的可用子帧，并且，在该可用子帧内，该资源栅格偏移信息生效。
在本实施例中，网络设备可以通过无线资源控制层信令承载该指示该资源栅格偏移信息生效的指示信息，在该可用子帧内，终端设备确定该资源栅格偏移信息指示的频域偏移量生效，在不可用子帧，终端设备确定该资源栅格偏移信息指示的频域偏移量无效，即按照原有的第一类型载波的资源栅格调度资源，进行数据的接收。
在本实施例中，该方法还可以包括：(可选，未图示)终端设备根据确定的可供调度的资源的频域位置以及网络设备的资源调度信息确定接收数据的资源，在该资源上接收网络设备发送的数据。
通过上述实施例可知，未来系统(例如NR)终端设备可以根据网络设备发送的资源栅格偏移信息，确定可供调度的资源的频域位置，使得MTC设备能够和未来系统(例如NR)设备对可供调度的资源的频域位置有相同的理解，从而使得MTC设备能够和未来系统(例如NR)设备在新类型载波上进行良好共存，并正常工作。
实施例3
图8是本实施例3的资源指示方法流程图，应用于终端设备侧。如图8所示，该方法包括：
步骤801，终端设备接收网络设备发送的配置信息，该配置信息包括在第一类型载波上配置的虚拟第二类型载波的相关信息；
步骤802，该终端设备根据该配置信息确定该虚拟第二类型载波的中心是直流子载波；且确定在该第一类型载波中，频域上的位置大于或等于该直流子载波位置的子载波所在的资源栅格偏移预定量。
在本实施例中，该第一类型载波和第二类型载波的具体实施方式可以参考实施例1，此处不再赘述，以下以该第一类型载波为NR载波，第二类型载波为LTE载波为例说明，但本实施例并不以此作为限制。
在本实施例中，网络设备可以在第一类型载波中预留一部分频域资源用作一个虚拟的第二类型载波，MTC设备收发数据占用的PRB被限制在此虚拟第二类型载波内；网络设备可以为该终端设备配置并发送该虚拟第二类型载波的相关信息，该相关信息包括：虚拟第二类型载波的位置和/或频带宽度。
在本实施例中，可以在上述网络设备RRC层配置的BWP相关信息BWP-DownlinkCommon中新建一个信息元(IE)携带该相关信息，也可以在其他信令中携带该相关信息，但本实施例并不以此作为限制，例如还可以使用现有的IE(locationAndBandwidth)来携带该相关信息，此处不再一一举例。该相关信息的实施方式与实施例1中网络设备为终端设备配置的BWP的相关信息BWP-DownlinkCommon类似，即该相关信息包括中心频点(或起始位置)、和/或带宽等信息，另外还可以包括虚拟第二类型载波标识信息，此处不再一一举例。
在本实施例中，在步骤802中，终端设备在接收到该配置信息后，确定该虚拟第二类型载波的中心是直流子载波，且该直流子载波不携带数据，网络设备根据该配置信息隐式的指示终端设备第一类型载波的资源栅格偏移信息，即终端设备根据该配置信息确定该第一类型载波的频域上的位置大于或等于该直流子载波位置的子载波所在的资源栅格偏移预定量，该预定量包括第二预定数量M个子载波，该第二预定数量为整数。
在一个实施方式中，根据该配置信息确定该第一类型载波的频域上的位置大于或等于该直流子载波位置的子载波所在的资源栅格偏移1个子载波，偏移方向是朝向 PRB index增大的方向，该第一类型载波的频域上的位置小于该直流子载波位置的子载波所在的资源栅格不偏移。
在一个实施方式中，根据该配置信息确定该第一类型载波的频域上的位置大于或等于该直流子载波位置的子载波所在的资源栅格偏移M(大于1)个子载波，偏移方向是朝向PRB index增大的方向，该第一类型载波的频域上的位置小于该直流子载波位置的子载波所在的资源栅格偏移M-1个子载波。
在本实施例中，该方法还可以包括：(可选，未图示)该终端设备接收该网络设备发送的用于指示该资源栅格偏移信息生效的指示信息，该步骤的实施方式可以参考实施例2，此处不再赘述。
通过上述实施例可知，未来系统(例如NR)终端设备可以根据网络设备发送的在第一类型载波上配置的虚拟第二类型载波的信息，确定可供调度的资源的频域位置，使得MTC设备能够和未来系统(例如NR)设备对可供调度的资源的频域位置有相同的理解，从而使得MTC设备能够和未来系统(例如NR)设备在新类型载波上进行良好共存，并正常工作。
实施例4
本实施例4还提供一种载波配置方法流程图，应用于网络设备侧。该方法包括：(未图示)网络设备向终端设备发送配置信息，该配置信息包括在第一类型载波上配置的虚拟第二类型载波的相关信息，该配置信息用于隐式的指示终端设备第一类型载波的资源栅格偏移信息，该配置信息的具体实施方式可以参考实施例3，此处不再赘述。
通过上述实施例可知，未来系统(例如NR)终端设备可以根据网络设备发送的在第一类型载波上配置的虚拟第二类型载波的信息，确定可供调度的资源的频域位置，使得MTC设备能够和未来系统(例如NR)设备对可供调度的资源的频域位置有相同的理解，从而使得MTC设备能够和未来系统(例如NR)设备在新类型载波上进行良好共存，并正常工作。
实施例5
本实施例5还提供一种资源指示装置。由于该装置解决问题的原理与实施例1 的方法类似，因此其具体的实施可以参考实施例1的方法的实施，内容相同之处不再重复说明。
图9是本实施例5的资源指示装置示意图。如图9所示，装置900包括：

在本实施例中，该偏移基准位置指示信息为物理资源块索引，该偏移基准位置可以根据第一类型载波上虚拟的第二类型载波的直流子载波的位置确定。其具体实施方式可以参考实施例1，此处不再赘述。
在本实施例中，该第一发送单元901、第二发送单元902的具体实施方式可以参考实施例1步骤401-402，此处不再赘述。
