终端设备可以是能够接收网络设备调度和指示信息的无线终端设备，无线终端设备可以是指向用户提供语音和/或数据连通性的设备，或具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端设备可以经无线接入网(如，radio access network，RAN)与一个或多个核心网或者互联网进行通信，无线终端设备可以是移动终端设备，如移动电话(或称为“蜂窝”电话，手机(mobile phone))、计算机和数据卡，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、平板电脑(Pad)、带无线收发功能的电脑等设备。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile station，MS)、远程站(remote station)、接入点(access point，AP)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户站(subscriber station，SS)、用户端设备(customer premises equipment，CPE)、终端(terminal)、用户设备(user equipment，UE)、移动终端(mobile terminal，MT)等。无线终端设备也可以是可穿戴设备以及下一代通信系统，例如，5G网络中的终端设备或者未来演进的公共陆地移动网络(public land  mobile network，PLMN)网络中的终端设备，NR通信系统中的终端设备等。
网络设备是网络侧中一种用于发射或接收信号的实体，如新一代基站(generation Node B，gNodeB)。网络设备可以是用于与移动设备通信的设备。网络设备可以是无线局域网(wireless local area networks，WLAN)中的AP，全球移动通信系统(global system for mobile communication，GSM)或码分多址(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的基站(NodeB，NB)，还可以是长期演进(long term evolution，LTE)中的演进型基站(evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的公共陆地移动网络(public land mobile network，PLMN)网络中的网络设备，或NR系统中的gNodeB等。另外，在本申请实施例中，网络设备为小区提供服务，终端设备通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与网络设备进行通信，该小区可以是网络设备(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(small cell)对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。此外，在其它可能的情况下，网络设备可以是其它为终端设备提供无线通信功能的装置。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。为方便描述，本申请实施例中，为终端设备提供无线通信功能的装置称为网络设备。
无线通信技术已经渗透到许多传统行业当中，并且衍生出很多新兴的应用，例如自动驾驶，远程医疗，智能机器人等。智能机器人是现代工业控制领域的重要应用，它不仅要求机器人的通信网络达到低时延高可靠的数据传输功能，而且需要从通信网络中获得统一的、标准的时钟信息，用以保证机器人之间协同工作。目前在某些高精度工业控制领域，要求机器人之间的绝对时钟偏差要在1微秒(us)以内，即机器人基于指令，同时进行操作，如同时搬运某个零部件，或2个机器手臂抬起零部件，其他手臂进行焊接、喷漆等操作。
目前标准讨论的方法是，网络设备和终端设备之间周期性的交互TSN相关信息，该信息可以在配置的configured grant(CG，免授权调度)资源或SPS(semi-persistent scheduling半静态调度)资源上进行传输，其中，CG目前应用在上行，SPS是下行。
在NR中，上行传输分为以下三种：
1、基于动态授权(grant)的上行传输。
即在下行控制信息中发送上行调度信息(UL grant in a DCI)。
2、没有动态grant的上行传输。
没有动态grant的上行传输也称为配置授权(configured grant，CG)或免授权(grant free，GF)。
该上行传输方式分为以下两种：
2.1、Configured grant Type1
该Type1是半静态调度(semi-persistent scheduling，SPS)，具体的，终端设备接收包含rrc-ConfiguredUplinkGrant的高层参数configuredGrantConfig，且不需要接收DCI，在协议中称为“configured uplink grant”。
终端设备接收到高层配置的参数后，即可在周期配置的时频资源上发送数据信息。
2.2、Configured grant Type2
该Type2类似于LTE中的SPS，终端设备先接收不包含rrc-ConfiguredUplinkGrant的高层参数configuredGrantConfig，再由L1信令激活或者去激活，称为“configured uplink grant based on L1signalling”。
终端设备接收到高层配置的参数，并在DCI中收到激活指令后，即可在周期配置的时频资源上发送数据信息。
在NR中，下行传输分为两种：
1、基于动态授权(grant)的下行传输
即在下行控制信息(Downlink control information，DCI)中发送下行调度信息(DL grant in a DCI)。
2、半静态调度(Semi-Persistent Scheduling，SPS)
SPS与上行传输中的Configured grant Type2相近，都是通过高层信令配置一些参数，再由DCI激活。
针对时间敏感网络(Time sensitive network，TSN)，TSN的业务是周期到达的，但业务的周期可能和目前协议配置的资源周期不能完全匹配。
目前NR协议给出的上行CG的资源周期的取值范围如表1所示：
表1 上行CG的资源周期的取值范围
Figure PCTCN2020072863-appb-000001
目前NR协议给出的下行CG的资源周期最小是10ms，后续可能会减小到1个时隙(slot)或者更小。
针对上述协议给出的多种资源的周期，可能存在协议给出的资源的周期的取值范围(或称为资源的周期的候选值)内找不到业务的周期的情形。比如，当业务的周期为3个符号或者16.67ms时，则上述资源的周期的取值范围中并没有3个符号或者16.67ms。
针对上述问题，目前给出的解决方案包括：
1)、配置更小的资源的周期。
该方法存在的缺陷是：可能导致资源的浪费。因为该方法可能需要把资源的周期配置 的非常小以便于可以匹配业务的周期，从而造成资源的浪费。
比如，业务的周期为6个slot，可能需要用1个slot的资源周期来满足要求，相当于每个业务的周期内配置了6份资源。此外，网络设备或终端设备需要频繁的检测数据，因为CG/SPS都是半静态调度，发送端每次发送数据不需要调度信令而是在提前配置的周期性的资源上进行发送，而如果发送端没有业务就不发送。而半静态配置导致接收端无法预知发送端是否有数据发送，所以就需要在对应的配置资源上进行盲检测数据，这样浪费功耗和资源。
2)、采用多套资源的周期联合配置。
该方法也存在资源浪费和功耗问题。例如业务的周期为3个slot，为了匹配则可能需要配置2套周期为2个slot的资源，且这两份资源错开一个slot，因此该2套周期为2个slot的资源可以联合得到周期为1个slot的资源配置。因此，当业务的周期为3个slot时，则在每份业务的周期上配置了3份资源，因此也会导致浪费功耗和资源。
并且，在方法2)的最小的资源的周期也是基于符号，如果业务的周期为非符号的整数倍，如0.833ms或者16.6667ms，则该方法2)也可能无法找到合适的资源的周期。
综上所述，上述两种实现方法都不能很好地解决业务的周期与资源的周期不匹配的问题。而且，随着业务的周期性的发送，业务和资源之间的偏差会不断累积，导致无法满足业务的时延要求。
为解决上述问题，本申请提供多种确定资源的方法，本申请给出的解决方案的总体思路是：对资源的使用时间进行动态调整，以使得业务的到达时间可以与调整后的资源的使用时间进行匹配。本申请中的“匹配”可以指重叠，即业务的到达时间与调整后的资源的使用时间重叠，或者也可以指“在一个预设的误差范围内”，即业务的到达时间与调整后的资源的使用时间的差值小于预设的误差/偏差。
本申请中，当候选的资源的周期(即资源的周期的取值范围、或资源的周期的候选值)中没有与业务的周期相同的周期时，作为一种实现方法，本申请可以从候选的资源的周期中选择一个与业务的周期最接近的一个资源的周期，作为该业务对应的资源的周期。比如，可以从候选的资源的周期中选择一个大于该业务的周期的最小周期，或者可以从候选的资源的周期中选择一个小于该业务的周期的最大周期。
为方便说明，本申请以从候选的资源的周期中选择一个大于该业务的周期的最小周期为例进行说明。
如图2所示，为本申请提供的资源的周期与业务的周期关系示例图。其中，业务的周期为Pt，资源的周期为P，且P-Pt＝d。该资源的周期P为候选的多个资源的周期中的大于该业务的周期的最小周期。由于业务的周期Pt和资源的周期P都是定值，因此，二者的差值d也是定值。
第一次业务到达时，资源的使用时间与业务的到达时间吻合(或重叠)，因此终端设备可以在R1时刻直接使用该资源；
第二次业务到达时，资源的使用时间还未到达，终端设备等待时长d之后，资源的使用时间才到达(即R2时刻)，因此业务的到达时间与资源的使用时间之间的偏差的累积值＝d；
第三次业务到达时，资源的使用时间还未到达，终端设备等待时长2d之后，资源的使用时间才到达(即R3时刻)，因此业务的到达时间与资源的使用时间之间的偏差的累积 值＝2d；
第四次业务到达时，资源的使用时间还未到达，终端设备等待时长3d之后，资源的使用时间才到达(即R4时刻)，因此业务的到达时间与资源的使用时间之间的偏差的累积值＝3d；
第五次业务到达时，资源的使用时间还未到达，终端设备等待时长4d之后，资源的使用时间才到达(即R5时刻)，因此业务的到达时间与资源的使用时间之间的偏差的累积值＝4d；
第六次业务到达时，资源的使用时间还未到达，终端设备等待时长5d之后，资源的使用时间才到达(即R6时刻)，因此业务的到达时间与资源的使用时间之间的偏差的累积值＝5d；
以此类推。
因此，随着时间增大，业务的到达时间与资源的使用时间之间的偏差的累积值会越来越大。为此，本申请给出的一种实现方法是：当业务的到达时间与资源的使用时间之间的偏差的累积值大于预设的偏差阈值时，则调整资源的使用时间，使得终端设备的业务的到达时间与资源的使用时间匹配。
如图3所示，为申请提供的一种确定资源的方法示意图。该方法由通信设备执行，该通信设备可以是终端设备，也可以是网络设备。也即，网络设备和终端设备都执行图3所示的方法，使终端设备和网络设备对于资源的使用时间做出相同的调整，以保证终端设备与网络设备之间通信的正确性。
该方法包括以下步骤：
步骤301，通信设备根据调整值，调整资源的使用时间，使终端设备的业务的到达时间与所述资源的使用时间匹配。
该业务为周期性业务，该资源为周期性资源。
步骤302，通信设备根据调整后的资源的使用时间，为业务确定传输资源。
基于上述方案，通信设备通过调整资源的使用时间，使终端设备的业务的到达时间与所述资源的使用时间匹配，从而可以实现终端设备的业务到达时间与资源的使用时间相匹配，减小了终端设备等待资源的延迟时间，有助于提升终端设备与网络设备之间的通信效率。
下面给出图3实施例的多种不同的具体实现方法，下面分别介绍。
实现方法1、终端设备和网络设备分别自主调整。
基于该实现方法，图3实施例的通信设备为终端设备时，则在步骤301之前，终端设备若确定终端设备的业务的到达时间与网络设备配置的资源的使用时间之间的偏差的累积值大于偏差阈值，则根据该累积值，确定上述调整值。
比如，参考图2，若预设偏差阈值为3.5d，则网络设备和终端设备可以预期当第五次业务到达时，确定此时的终端设备的业务的到达时间与网络设备配置的资源的使用时间之间的偏差的累积值等于4d，因此大于偏差阈值，因而触发终端设备根据该累积值确定上述调整值。比如，当该累积值是符号或时隙的整数倍时，可以将该累积值作为调整值；再比如，当该累积值不是符号或者不是时隙的整数倍时，则可以对该累积值稍微处理，比如四舍五入为符号的整数倍或时隙的整数倍，得到一个调整值。
或者也可以是，在偏差的累积值超过预设偏差阈值后再进行调整，如本例子中在第五 次累计偏差值达到4d，超过了预设阈值3.5d之后，调整第六次业务对应的资源的使用时间。
比如，参考图2，可以将资源出现的时间R5往前调整一个调整值(图2中用R表示)，使得该资源的调整后的使用时间为R5’，即使终端设备的业务的到达时间与所述资源的使用时间匹配。从而终端设备无需等待，可以快速使用资源进行收发数据，可以减小时延和提升通信效率。
可选的，该预设的偏差阈值可以是预配置的，或协议预定义的。具体的，所述偏差阈值的确定可以是网络设备确定，并提前通过信令配置给终端设备的；也可以是终端设备和网络设备根据所述业务的时延要求确定的，如所述偏差阈值等于所述业务的时延要求，或所述偏差阈值等于所述业务的时延要求的一半，或所述时延要求中减掉硬件设备误差值的最大值。其中，时延要求可以是接收端等待接收发送端发送的数据的最大等待时长。
基于该方案，则终端设备根据调整值调整资源的使用时间的方法，包括但不限于以下方法：
方法1，终端设备根据该调整值，在预设的时间范围内，调整资源的使用时间，使终端设备的业务的到达时间与所述资源的使用时间匹配。
方法2，终端设备根据该调整值，在约定的后续第N次业务到达之前或之后，调整资源的使用时间，N为正整数，使终端设备的业务的到达时间与所述资源的使用时间匹配。
即，调整第N次或第(N+1)次或第(N-1)次业务对应的资源的使用时间。
比如，N为1，则终端设备根据该调整值，在约定的后续第1次业务到达之前，调整资源的使用时间。再比如，N为2，则终端设备根据该调整值，在约定的后续第2次业务到达之前，调整资源的使用时间，等等。
方法3，终端设备确定出调整值后，触发终端设备启动预配置的定时器，终端设备根据该调整值，在定时器超时前调整资源的使用时间，或者，根据该调整值对定时器超时后的第一个资源的使用时间进行调整，使终端设备的业务的到达时间与所述资源的使用时间匹配。
对于网络设备，也使用与上述终端设备相同的方法，对资源的使用时间进行调整，使终端设备的业务的到达时间与所述资源的使用时间匹配。可以参考前述表述，不再赘述。
实现方法2、网络设备自主调整，并通知终端设备进行相应调整。
基于该方法，网络设备可以预先获取各个业务的业务属性，如业务的周期等，因此网络设备可以自主调整，并通知终端设备进行相应调整。
其中，网络设备自主调整的具体实现方法，可以参考上述实现方法1中网络设备的调整方法，不再赘述。
针对终端设备，则是由网络设备通知其进行调整。具体的，当网络设备确定需要对资源的使用时间进行调整时，比如网络设备若确定终端设备的业务的到达时间与网络设备配置的资源的使用时间之间的偏差的累积值大于偏差阈值，则根据该累积值，确定调整值，并根据该调整值，通知终端设备进行调整。
可选的，网络设备向终端设备发送通知信令，该通知信令用于通知终端设备调整资源的使用时间。该通知信令可以是DCI、或媒体接入控制控制单元(medium access control control element，MAC CE)，或者无线资源控制(Radio Resource Control，RRC)信令。
可选的，该通知信令指示了调整值，该通知信令指示调整值的实现方法包括但不限于 以下方法：
方法1、通知信令包括上述调整值。
比如，该调整值为如2、4等，单位可以是符号、时隙、毫秒、微秒等。
方法2、通知信令包括指示信息，该指示信息用于指示预定义的多个调整值中的一个。
比如，终端设备预设或是网络设备向终端设备预配置(如半静态配置)了多个候选的调整值，该通知信令通过该指示信息的不同取值(即比特状态)来指示不同的调整值。比如，指示信息为2比特，高层配置0，2符号，4符号，8符号四种调整值，则可以用指示信息分别为00,01,10,11来指示网络设备期望终端设备进行调整的具体数值(即调整值)。当然，网络设备也按照同样的调整值进行调整。
方法3，网络设备不通知调整值。
该方法中，终端设备和网络设备预先约定好相同的调整值的计算方法，则终端设备收到该通知信令后，触发终端设备计算调整值，并根据该调整值对资源的使用时间进行调整。
可选的，该通知信令可以包括1比特信息，当终端设备确定该1比特信息为“1”时，则触发终端设备计算调整值，并根据该调整值对资源的使用时间进行调整。
可选的，基于上述指示调整值的任一实现方法，该通知信令还可以包括一个或多个终端设备的标识。或者，该通知信令包括一个终端组标识，该终端组标识用于指示一个终端群组，该终端群组包括一个或多个终端设备。如用不同的标识(ID)来标识不同的终端设备，用不同的终端组标识来标识不同的终端组，或配置不同的信令资源位置来区别不同的终端设备或终端组。
其中，该调整信令可以通知一个终端群组内的终端设备按照相同的调整值进行调整，或者该调整信令也可以实现通知终端群组内的不同终端设备按照不同的调整值进行调整。比如，利用上述方法2，调整信令包括指示信息，该指示信息为“11”时，则不同的终端设备对于“11”的理解不同，比如终端设备1理解为“11”对应的调整值是3个符号，终端设备2理解“11”对应的调整值是5个符号等等，从而实现一个调整信令指示不同终端设备按照不同的调整值进行调整。
基于该实现方法2，则终端设备接收到通知信令后，根据调整值，调整资源的使用时间，具体的方法包括但不限于以下方法：
方法1、终端设备根据调整值，在预设时间范围内，调整资源的使用时间。
方法2、终端设备根据调整值，在约定的后续第N次业务到达之前或之后，调整所述资源的使用时间，N为正整数。
该资源可以是第N次业务对应的资源，也可以是第N-1次业务对应的资源，也可以是第N+1次业务对应的资源。
方法3、通知信令包括调整时间；则通信设备根据调整值，在该调整时间内，调整资源的使用时间。
方法4、终端设备在收到通知信令后，启动预配置的定时器，并根据调整值在定时器超时前调整资源的使用时间，或者，根据调整值对定时器超时后的第一个资源的使用时间进行调整。
下面给出该实现方法2的一种具体实现方式。
比如，上述通知信令是一个DCI。目前，CG type2和SPS的激活/去激活都是采用DCI来做的，具体协议中是通过以下表格2，将某些信息域设为固定值来传递消息，已通知终 端设备激活，如某个或多个域都设置为全“0”；以及，通过以下表格3，将某些信息域设为固定值来传递消息，已通知终端设备去激活，如某个或多个域都设置为全“0”或“1”。
如表2所示，为激活的表格。如表3所示，为去激活的表格。
表2 激活的表格
Figure PCTCN2020072863-appb-000002
表3 去激活的表格
Figure PCTCN2020072863-appb-000003
根据表2，可以看到，当DCI中用于指示重传进程号和冗余版本的所有比特均设置为“0”时，表示该DCI用于指示终端设备激活。
根据表3，可以看到，当DCI中用于指示重传进程号和冗余版本的所有比特均设置为“0”、且用于指示调制编码方式和频域资源分配的所有比特均设置为“1”时，表示该DCI用于指示终端设备去激活。
基于上述现有的定义，本申请可以新增以下表格4，该表格4用于指示终端设备进行资源的使用时间的调整。
表4 资源的使用时间的调整的指示
Figure PCTCN2020072863-appb-000004
基于表4，本申请定义如下：当DCI中用于指示重传进程号、冗余版本、调制编码方式和频域资源分配的所有比特均设置为“0”时，表示该DCI用于指示终端设备对资源的使用时间进行调整。
基于该表4，关于资源的使用时间的调整值，则可以使用DCI中的时域资源分配域(time domain resource assignment)进行指示。
目前，时域资源的指示方法为高层预先配置多组(最多16组)信息，每组信息可以指示出时域资源的slot偏移(DCI和数据之间的时偏，即收到DCI后多少个slot发送数据信息)，slot内的起始符号和发送信息的持续时间。基站实际调度的时候，在DCI的时域资源分配域指示出采用哪组预配置的信息(最多4比特)。本发明可以复用该指示域(4比特)对调整值进行指示：
方法1、复用现有的指示方法，DCI的时域资源分配域指示收到DCI后的下一次数据传输的时间信息，而其他信息，如频域资源、周期、调制与编码策略(Modulation and Coding Scheme，MCS)等这些信息都沿用之前的指示，可以不做改变。当然，也可以在频率资源、MCS等域指示，新的取值或对应的频率/MCS调制值，用其他信息的固定值指示该DCI类型，这里不做限制。
基于该方法，则DCI的时域资源分配域指示的信息可以表示调整后的使用资源的时间位置，单位可以是符号、slot等。
即该方法通过DCI的时域资源分配域可以指示16个时间位置中的一个，并将该位置作为调整后的使用资源的时间位置。
方法2、由于DCI的时域资源分配域为4比特因此可以定义指示可以使用4比特中2比特指示slot，2比特指示符号，从而4比特构成一个调整值；或者是4比特均用于指示符号；或者是3比特用于指示slot，1比特用于指示符号，等等。或者，4比特中1比特用于指示所述调整值为负值或正值，即向前调整还是向后调整，4比特中3比特用于指示所述调整值。
基于该方法，在DCI的时域资源分配域中携带具体的调整值。
方法3，由于DCI的时域资源分配域为4bits，因此可以预先定义16个调整值的取值，然后通过4比特指示16种调整值中的一种。
实现方法3、网络设备基于终端设备的触发进行调整，并通知终端设备进行相应调整。
该实现方法3与上述实现方法2类似，但不同点在于：对于上行的TSN数据发送，网络设备并不知道终端设备的业务的周期，或者由于终端设备的业务的到达时间存在抖动(比如终端设备的时钟存在偏差等原因导致抖动)，而导致网络设备不能准确地获取网络设备确定使用的资源与业务的到达时间之间的偏差值，因而网络设备不能准确地得到上述调整值。
因此，该实现方法3中，在实现方法2的基础上，在网络设备确定调整值之前，终端设备确定调整参考值，然后终端设备向网络设备发送该调整参考值，该调整参考值用于辅助网络设备确定调整值，即网络设备可以根据该调整参考值，确定调整值。
其中，终端设备可以用以下方法确定调整参考值：终端设备确定业务的到达时间与资源的使用时间之间的偏差的累积值大于预设的偏差阈值时，则将此时的累积值作为调整参考值，或者是根据该累积值得到上述调整值，并该将调整值作为调整参考值。该实现方法3的其它部分内容，与上述实现方法2相同，可以参考前述描述。
或者，在又一种实现方法中，所述终端设备也可以不发送上述调整参考值，而是向网络设备发送一个上行信令，以触发网络设备进行资源的使用时间的调整或重配，则网络设备在接收到该上行信令后，可以按照如上述实现方法的方法对网络设备的资源的使用时间进行调整，以及通知终端设备对资源的使用时间进行调整。
此外，本申请还给出另外一种解决背景技术问题的实现方法4，该实现方法4与图3实施例及上述实现方法1-3均为不同的方法。
实现方法4、增加缩放因子。
目前的资源的周期的配置方法之所以有资源浪费的问题，是因为资源的周期的候选值中可能不存在与业务的周期相同的资源的周期，而如果只是简单的目前的资源的周期的候选值基础上增加更多的资源的周期的候选值，则将导致资源的周期的候选值的总数量比较多，这将需要更多的比特来指示这些信息。比如，当资源的周期的候选值为8个时，需要3比特指示；当资源的周期的候选值为9-16个时，则需要4比特指示，等等。
基于此，本申请的该实现方法4中，在现有的资源的周期的候选值的基础上不再增加资源的周期的候选值，而是在资源的周期的候选值中不存在与终端设备的业务的周期相匹配的周期时，通过增加一个缩放因子，来指示为该终端设备的业务选择的资源的周期。
比如，业务的周期为6个slot，15kHz对应的资源的周期的候选值包括：2,7,n*14,其中，n＝{1,2,4,5,8,10,16,20,32,40,64,80,128,160,320,640}，可以发现资源的周期的候选值中并不存在周期为6个slot，则网络设备可以为该终端设备配置资源的周期为2个slot，以及确定缩放因子等于3，因此网络设备将资源的周期(值为2slot)和缩放因子(值为3)通过DCI发送给终端设备，则终端设备可以计算得到网络设备配置的实际的资源的周期为：2slot*3＝6slot。即，该示例中，网络设备为终端设备实际配置的资源的周期是6个slot，且通过资源的周期为2slot和缩放因子为3来通知终端设备。
其中，缩放因子可以是整数值，如3等，也可以是小数值，如0.5等。
网络设备可以在为终端设备配置的资源的周期的信令中携带缩放因子，也可以是在独立的信令中携带缩放因子，可以是高层信令或者是动态信令中携带缩放因子。
该实现方法，不需要增加资源的周期的候选值，且可以实现为终端设备配置更多的适配周期值。因而实现了在不显著增加信令开销的前提下，实现了为终端设备配置合适的资源的周期。
