相关申请的交叉引用
本申请基于申请号为201710687231.8、申请日为2017年08月11日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及但不限于通信领域，尤其涉及一种资源位置的指示、接收方法、装置、设备及存储介质。
背景技术
在未来无线通信系统(例如第五代移动通信技术(5G，5th-Generation))中，将会采用比第四代通信系统所采用的载波频率更高的载波频率进行通信，比如28GHz、45GHz等等，5G new无线接入技术(Radio Access Technology，RAT)系统潜在工作频段达到100GHz。由于高频通信对应的载波频率具有更短的波长，所以可以保证单位面积上能容纳更多的天线元素，而更多的天线元素意味着可以采用波束赋形的方法来提高天线增益，从而保证高频通信的覆盖性能。
采用波束赋形的方法后，发射端可以将发射能量集中在某一方向上，而在其它方向上能量很小或者没有，也就是说，每个波束具有自身的方向性，每个波束只能覆盖到一定方向上的终端，发射端即基站需要在几十个甚至上百个方向上发射波束才能完成全方位覆盖。现有技术中，倾向在终端初始接入网络的过程中进行初步波束方向的测量与识别，并集中在一个时间间隔内将基站侧发射波束轮询一遍，供终端测量识别优选的波束或端口。具体的，在一个同步信号发送周期内有多个同步信号块(SS block)， 每个SS block内承载特定波束/端口(组)的同步信号，一个同步信号发送周期完成一次波束扫描，即完成所有波束/端口的发送。
在现有技术中，物理载波中心频点(即直流频率)被放置在各个信道号(channel number)对应的频域位置上。相邻信道号之间的频率间隔被称为信道栅格(channel raster)或载波栅格(carrier raster)间隔。终端搜索同步信号的频域步长被称为频率栅格(frequency raster)或终端栅格(UE raster)间隔。在LTE系统中，终端栅格间隔与信道栅格间隔相同，即终端在所有可能的信道号(即信道编号)对应的频域位置上搜索同步信号，图1是现有技术中终端栅格与信道栅格相同的示意图，如图1所示。
在NR中，为了更灵活地进行频谱部署，并降低终端频域搜索的复杂度，工业界提出使用更大的终端栅格间隔，即终端栅格间隔可以大于信道栅格间隔。在这种情况下，同步信号、广播信道或其它相关信号/信道的中心频点很可能与物理载波的中心频点不同。目前标准讨论中已经确定了最小载波带宽以及同步带宽，这就意味着确定了终端栅格间隔的最大值，而且终端栅格间隔的最小值大于或等于信道栅格间隔。如果终端栅格间隔取中间的某个值，由于NR系统带宽通常较大，因此一个物理载波带宽在频域上可能包含多个SS blocks。
另外，高频通信的工作带宽通常较高，高达几百MHz，为了减小资源调度开销，也为了让小带宽能力的终端能够正常通信，相关技术中可以将未来无线通信系统(New Radio，NR)的物理载波带宽划分成多个带宽部分(Bandwidth part，BWP)，在BWP内为终端调度用于数据传输的资源，或者向终端传输广播类的信息。在NR中，公共控制信息承载在公共控制资源集common CORESET(s)中，是非常重要的信息，例如寻呼、部分UE specific的控制信息以及部分广播类型的信息都与公共控制信息有关，common CORESET(s)调度的频谱资源需要在某个BWP或者物理下行共享信道(Physical Downlink Shared Channel，PDSCH)资源内，因此基站如何 指示BWP、PDSCH以及common CORESET(s)的资源位置至关重要。

可选实施例1
本可选实施例描述利用相对于参考点的频域上的偏移指示第一和第二资源的频域位置。
如图3给出了SS block、BWP以及Common CORESET在NR载波中的频域位置，其中，n为SS block的中心频点对应的信道编号，m为BWP的中心频点对应的信道编号，m+k为Common CORESET中心频点对应的信道编号。

表1
Figure PCTCN2018098377-appb-000001
在一实施例中，基站可以利用物理广播信道或者RRC专用信令向终端发送BWP和Common CORESET的中心频点相对于SS block中心频点的偏移量、左右偏移指示以及BWP和Common CORESET的带宽等信息，或者，一部分利用物理广播信道，一部分利用RRC专用信令向终端发送BWP和Common CORESET的中心频点相对于SS block中心频点的偏移量、左右偏移指示以及BWP和Common CORESET的带宽等信息。
在一实施例中，所述RRC专用信令也可以由相邻基站发送给终端。
用相对信道编号来表示BWP或者Common CORESET的中心频点相对于SS block的中心频点的偏移仅仅是一个示例。如果BWP或者Common CORESET的中心频点与SS block的中心频点之间的频率差不是信道栅格的整数倍，则仅仅用相对信道编号无法准确表示BWP或者Common CORESET的中心频点相对于SS block的中心频点的偏移，这时需要考虑其它的方法。
BWP或者Common CORESET的中心频点相对于SS block的中心频点的偏移还可以用BWP或者Common CORESET的中心频点相对于SS block的中心频点的相对子载波编号来表示，其中相对子载波编号指BWP或者Common CORESET的中心频点所在频域位置与SS block的中心频点所在的频域位置相差的子载波数，BWP或者Common CORESET的中心频点高于 SS block的中心频点时是右偏移，BWP或者Common CORESET的中心频点低于SS block的中心频点时是左偏移。比如BWP的中心频点所在的频域高于SS block的中心频点所在的频率(子载波按照由低频到高频递增的顺序编号)，且两者相差K个子载波波，则BWP的中心频点相对于SS block的中心频点的偏移为相对子载波编号为K，且为右偏移；或者，
用BWP或者Common CORESET的中心频点相对于SS block的中心频点的相对PRB编号来表示；或者，
用BWP或者Common CORESET的中心频点相对于SS block的中心频点的相对PRB编号，以及BWP或者Common CORESET的中心频点相对于相对PRB编号对应的频域位置的相对子载波编号来表示；或者，
用BWP或者Common CORESET的中心频点相对于SS block的中心频点的相对信道编号以及BWP或者Common CORESET的中心频点相对于相对信道编号对应的频域位置的相对子载波编号来表示；或者，
用BWP或者Common CORESET的中心频点相对于SS block的中心频点的相对信道编号以及BWP或者Common CORESET的中心频点相对于相对信道编号对应的频域位置的相对PRB编号来表示；或者，
用BWP或者Common CORESET的中心频点相对于SS block的中心频点相对信道编号以及BWP或者Common CORESET的中心频点相对于相对信道编号对应的频域位置的相对PRB编号，以及BWP或者Common CORESET的中心频点相对于相对PRB编号对应的频域位置的相对子载波编号来表示。
对于第一资源和第二资源的带宽不限于表1中的指示方式，也可以预定义N1种带宽，则只需用log2(N1)比特信息就可以表示某个资源的带宽，比如4种带宽：100个RB，50RB，30个RB，20个RB。则只需用2比特信息就可以表示某个资源的带宽。
如果BWP的带宽是固定的，比如50个RB，则基站无需向终端指示 BWP的带宽。同样地，如果Common CORESET的带宽是固定的，比如20个RB，则基站无需向终端指示Common CORESET的带宽。也就是说基站只需向终端指示BWP或者Common CORESET的中心频点相对于SS block的中心频点的偏移就可以了。
另外，如果BWP或者Common CORESET的中心频点相对于SS block的中心频点的偏移是固定的，例如偏移量和左右偏移是固定的，则基站只需向终端指示带宽的大小，如果仅仅偏移量固定，则只需指示是左偏移还是右偏移，以及带宽的大小。
另外，BWP或者Common CORESET的位置也可以用BWP或者Common CORESET的边界(例如左边界，即起始频域位置，或者右边界，即终止频域位置)相对于SS block的中心频点的偏移来指示，可以用相对于参考点偏移的RB数来表示，例如偏移0个RB表示与SS block中心频点位置重合，指示方法与用BWP或者Common CORESET的中心频点相对于SS block的中心频点的偏移的指示方法类似。
在一实施例中，可以利用1比特的左右偏移指示以及资源指示值(Resource Indication Value，RIV)，来指示BWP或者Common CORESET的中心或者边界(例如左边界，即起始频域位置，或者右边界，即终止频域位置)相对于SS block的中心频点的偏移量和BWP的带宽或者Common CORESET的带宽。
所述RB的带宽可以是根据SS block采用的子载波间隔确定的，也可以是PBCH或者最小系统信息(RMSI)或者RRC专用信令通知的子载波间隔确定的。一个RB在频域上包含12个子载波。
另外需要说明的是：如下两种情况基站向终端指示资源的方式与上述实施例类似：1)第一资源是下行业务信道PDSCH占用的资源，第二资源是Common CORESET；2)第一资源是Common CORESET，第二资源是BWP或者下行业务信道PDSCH占用的资源。
上述实施例中，参考点以SS block的中心频点为例进行说明，参考点为NR载波的中心或者边界、下行同步信号带宽的中心或者边界、SS block边界时可以采用类似的方式指示BWP或者Common CORESET的中心频点相对于参考点的偏移。例如参考点为SS block的右边界时，表2给出了BWP和Common CORESET的中心频点相对SS block的右边界频点的偏移和带宽。
表2
Figure PCTCN2018098377-appb-000002
综上，BWP或者Common CORESET的位置是中心频点、边界中任意一个，参考点是NR载波的中心或者边界、下行同步信号带宽的中心或者边界、SS block的中心或者边界中任意一个时，都可以采用上述实施例类似的方法来指示BWP或者Common CORESET的频域位置。
可选实施例2
本可选实施例描述利用相对于参考点的频域上的偏移指示第一资源的频域位置，利用相对于第一资源的频域上的偏移指示第二资源的频域位置。
如图4给出了SS block、PDSCH以及Common CORESET在NR载波中的频域位置，其中，k1、k2和k3分别为SS block、PDSCH以及Common CORESET的中心频点对应的子载波编号，基站可以利用Common CORESET承载的PDCCH调度PDSCH占用的资源。第一资源以PDSCH 占用的资源为例，第二资源以Common CORESET为例，参考点以SS block的中心为例。在本实施例中基站向终端指示PDSCH的中心频点相对于SS block中心频点的偏移和PDSCH的带宽，以及Common CORESET的中心频点相对于PDSCH的中心频点的偏移和Common CORESET的带宽，具体指示的内容包括相对子载波编号、左右偏移指示和带宽，如表3所示。
其中，PDSCH的中心频点相对于SS block的中心频点的相对子载波编号指PDSCH的中心频点所在频域位置与SS block的中心频点所在的频域位置相差的子载波数，PDSCH的中心频点高于SS block的中心频点时是右偏移，PDSCH的中心频点低于SS block的中心频点时是左偏移。
其中，Common CORESET的中心频点相对于PDSCH的中心频点的相对子载波编号指Common CORESET的中心频点所在频域位置与PDSCH的中心频点所在的频域位置相差的子载波数，Common CORESET的中心频点高于PDSCH的中心频点时是右偏移，Common CORESET的中心频点低于PDSCH的中心频点时是左偏移。
表3
Figure PCTCN2018098377-appb-000003
对于第一资源是Common CORESET、第二资源是PDSCH占用的资源的情况，可以采用类似的方式来指示。具体地，基站向终端指示Common CORESET的中心频点相对于SS block中心频点的偏移和Common  CORESET的带宽，以及PDSCH的中心频点相对于Common CORESET的中心频点的偏移和PDSCH的带宽，具体指示的内容包括相对子载波编号、左右偏移指示和带宽，如表4所示。需要注意的是由于PDSCH的中心频点低于Common CORESET的中心频点，因此指示PDSCH的中心频点相对于Common CORESET的中心频点的偏移时，左右偏移指示为0，即PDSCH的中心频点相对于Common CORESET的中心频点是左偏移。
表4
Figure PCTCN2018098377-appb-000004
如果PDSCH的带宽是固定的，比如50个RB。则基站无需向终端指示PDSCH的带宽。同样地，如果Common CORESET的带宽是固定的，比如20个RB。则基站无需向终端指示Common CORESET的带宽。
基站可以利用物理广播信道或者RRC专用信令向终端通知PDSCH、Common CORESET的频域位置，或者，利用物理广播信道通知PDSCH占用的资源的频域位置，利用RRC专用信令通知Common CORESET的频域位置，或者，利用物理广播信道通知Common CORESET的频域位置，利用RRC专用信令通知PDSCH专用的资源的频域位置。其中所述RRC专用信令也可以由相邻基站发送给终端。
可选实施例3
本可选实施例描述利用相对于参考点的频域上的偏移指示第一资源的 频域位置，第二类节点根据预定义规则计算第二资源的频域位置。
如图5给出了SS block、BWP以及Common CORESET在NR载波中的频域位置。第一资源以BWP为例，第二资源以Common CORESET为例，参考点以SS block的中心为例。在本实施例中基站向终端指示BWP的中心频点相对于SS block中心频点的偏移和BWP的带宽，Common CORESET的带宽，具体指示的内容包括相对子载波编号、左右偏移指示和带宽，如表5所示，其中-表示所述项不存在。
其中，BWP的中心频点相对于SS block的中心频点的相对子载波编号指BWP的中心频点所在频域位置与SS block的中心频点所在的频域位置相差的子载波数，BWP的中心频点高于SS block的中心频点时是右偏移，PDSCH的中心频点低于SS block的中心频点时是左偏移。
终端根据预定义规则计算Common CORESET的中心频点相对于BWP的中心频点的偏移。
所述预定义规则定义了一个或多个因素和Common CORESET的中心频点相对于参考点或者BWP的中心频点的偏移量之间的关系，所述因素包括如下至少一项：同步信号块索引、物理小区标识、系统帧号、频带信息。
所述预定义规则可以是一个默认频域偏移量，例如偏移4个RB；也可以根据定时信息、物理小区标识、频带信息中任意一项或多项来定义，具体地例如：SS block index，物理小区标识Cell ID，系统帧号(System Frame Number，SFN)，频带范围等。其中SS block index是终端完成下行同步时同步信号所在的SS block的Index，SFN是终端完成下行同步时同步信号所在的无线帧的编号。频带范围是提前划分好的，每个频带范围对应唯一一个频带范围标识。确定预定义规则的原则是根据不同的SS block index(组)、物理小区标识Cell ID(组)、系统帧号SFN(组)、频带范围(组)计算的Common CORESET的中心频点相对于BWP的中心频点的偏移尽可能不同，以减小使用Common CORESET传输信息时相邻小区间的相互干扰。
例如，预定义规则可以是SS block index N2对应Common CORESET的中心频点相对于BWP的中心频点偏移N2个RB；或者，
SS block index N2对应Common CORESET的中心频点相对于BWP的中心频点偏移K*floor(N2/M)个RB，其中floor表示下取整；或者，
SS block index N2对应Common CORESET的中心频点相对于BWP的中心频点偏移K*mod(N2，M)个RB，其中mod是取模运算；或者，
也可以采用类似的方式，根据物理小区标识Cell ID，SFN，频带范围确定预定义规则。
例如，预定义规则是偏移K*floor(X/M)或者K*mod(X，M)个RB，其中X可以是Cell ID，SFN，频带范围标识。
预定义规则也可以是上述各种方式的组合，例如偏移K*floor(N2/M)+L*mod(Cell ID，M)个RB。
在上述公式中，N2和X是非负整数，K和L是正整数，M是大于1的整数。
例如以终端成功完成下行同步的同步信号所在的SS block index为2为例，按照预定义规则SS block index N2对应Common CORESET的中心频点相对于BWP的中心频点偏移N2个RB，则Common CORESET的中心频点相对于BWP的中心频点偏移2个RB，然后再根据左右偏移指示1和Common CORESET的带宽为20个RB，就可以知道Common CORESET的频域位置。
上述偏移量以RB为单位仅仅是举例，实际偏移量不限于RB，可以是任何能够度量频率的单位，例如Y kHz/MHz，RB组，子载波，子载波组，信道栅格，信道栅格组等。
如下几种情况基站向终端指示资源的方式与上述实施例类似：1)第一资源是Common CORESET，第二资源是BWP；2)第一资源是Common CORESET，第二资源是下行业务信道PDSCH占用的资源；3)第一资源是 下行业务信道PDSCH占用的资源，第二资源是Common CORESET。主要思想都是第一资源是相对于参考点指示的频域上的偏移，第二资源是相对于第一资源且由终端根据预定义规则计算的频域上的偏移。
表5

可选实施例4
本可选实施例描述通过指示BWP索引来指示BWP的频域位置。
基站将系统带宽(即物理载波的带宽)均匀划分若干个BWP，如图6所示基站将物理载波划分成4个BWP，对应索引分别为0，1，2，3。假设终端已经知道了物理载波的中心频点以及系统带宽内BWP的划分方式，则基站可以利用2比特信息，直接向终端指示BWP的索引，例如直接向终端指示BWP的索引为3，终端根据物理载波的中心频率和带宽以及BWP的划分方式就可以获得BWP3的频域位置，就可以知道Common CORESET承载的控制信息调度的资源位于BWP3内。这样做的好处是与指示BWP3相对参考点的偏移以及带宽相比大大地降低了指示BWP3频域位置的开销。
另外，基站可以通过上述各实施例中的方法指示Common CORESET的频域位置，这里就不在赘述。
基站可以利用RRC专用信令向终端指示BWP索引、Common  CORESET的频域位置，或者，利用物理广播信道通知BWP索引，利用RRC专用信令通知Common CORESET的频域位置，或者，利用物理广播信道通知Common CORESET的频域位置，利用RRC专用信令通知BWP索引。
可选实施例5
本可选实施例描述利用指示配置的SS block的频域位置索引，以及指示Common CORESET相对配置的SS block的频域位置的偏移，来指示资源的频域位置。
基站在系统带宽内配置一个或者多个SS block，每个SS block的频域位置对应一个索引，如图7所示，基站在系统带宽内配置了两个SS block，对应索引分别为0，1，假设终端已经知道了每个SS block的频域位置，以及它所在的BWP和BWP的带宽。则基站可以利用1比特信息，直接向终端指示配置的SS block的频域位置索引，终端根据SS block的配置信息就可以获得配置的SS block的频域位置，就可以知道Common CORESET承载的控制信息调度的资源位于BWP2内。这样做的好处是与指示BWP2相对参考点的偏移以及带宽相比大大地降低了指示BWP2频域位置的开销。
然后基站向终端指示Common CORESET的中心频点或者边界相对配置的SS block的中心频点或者边界的偏移，以及Common CORESET的带宽，以便终端获取Common CORESET资源的频域位置，终端再根据Common CORESET调度的资源所在的BWP(即BWP2)以及用其他方法获取的Common CORESET资源的时域位置，就可以成功地获得Common CORESET携带的信息。
可选实施例6
本可选实施例描述了利用Common CORESET资源的带宽与BWP或者PDSCH的资源的带宽的关系联合指示Common CORESET、BWP和PDSCH的带宽的方法。
如果第一资源的带宽和第二资源的带宽有固定的关系，则可以联合指 示第一资源和第二资源的带宽。假设第一资源的带宽和第二资源的带宽有多种固定关系，可以指示其中一个资源的带宽，以及指示两个资源的带宽属于哪种关系。
例如第一资源为BWP，第二资源为Common CORESET，则第一资源的带宽和第二资源的带宽有2种关系：1)第二资源的带宽与第一资源的带宽相同；2)第二资源的带宽是第一资源的带宽的一半。基站只需指示第一资源的带宽，以及第一资源的带宽和第二资源的带宽间的关系是第一种或者第二种即可，而不必分别指示两个资源的带宽，从而节省指示的资源开销，尤其是带宽较大时。
可选实施例7
本可选实施例以指示BWP的频域位置为例，描述了指示资源的频域位置的具体实现方法。
可以利用1比特的左右偏移指示以及资源指示值RIV，来指示BWP的边界或者中心相对于参考点的偏移和BWP的带宽，包括以下几种情况：
1)BWP的带宽是固定的，也就是说BWP的带宽对于基站和终端是事先知道的，则RIV占用的比特数由BWP左边界或者右边界或者中心相对于参考点的最大偏移量确定，即由表示最大偏移量需要的比特数来确定，RIV的取值等于BWP的左边界或者右边界或者中心相对于参考点的偏移量。例如，最大偏移量为31个RB，BWP中心相对于参考点的偏移量为12个RB，因为表示最大偏移量至少需要5比特信息，因此RIV占用的比特数为5，RIV＝12，用二进制表示RIV＝01100。
2)BWP的带宽不是固定的，且参考点在BWP的外面，指示方法：当BWP位于参考点的右侧时，指示BWP的左边界以及带宽；当BWP位于参考点的左侧时，指示BWP的右边界以及带宽，具体地，BWP的边界相对于参考点的最大偏移量为物理载波带宽或者固定值，基站根据BWP的边界相对于参考点的偏移量、BWP的带宽确定RIV值，将RIV值发送给终端， 然后终端根据收到的RIV值反计算出BWP的边界相对于参考点的偏移量以及带宽，再根据获取的左右偏移指示，从而获得BWP的边界位置以及带宽。假设最大偏移量为物理载波带宽，用N个RB表示。用L表示BWP的带宽为L个RB，用S表示BWP的边界相对于参考点的偏移量为S个RB，BWP的左边界位于参考点的右侧，如图8所示；BWP的右边界位于参考点的左侧，如图9所示。则RIV占用的比特数为
Figure PCTCN2018098377-appb-000006
RIV的取值为：
如果
Figure PCTCN2018098377-appb-000007
则RIV＝N(L-1)+S          公式1
否则RIV＝N(N-L+1)+N-1-S                公式2
终端接收到RIV后先计算
Figure PCTCN2018098377-appb-000008
的值。
对于公式1，
Figure PCTCN2018098377-appb-000009
对于公式2，
Figure PCTCN2018098377-appb-000010
其中％表示取余运算，由于L+S≤N(否则BWP就会超出物理载波的带宽范围)，因此对于公式1，
Figure PCTCN2018098377-appb-000011
而对于公式2，
Figure PCTCN2018098377-appb-000012
因此终端根据
Figure PCTCN2018098377-appb-000013
的值与N的大小关系就可以知道RIV的计算采用的是公式1还是公式2。
如果采用的是公式1，则
Figure PCTCN2018098377-appb-000014
S＝RIV％N；如果采用的是公式2，则
Figure PCTCN2018098377-appb-000015
S＝N-1-RIV％N。终端获得了S和L的值，也就获得了BWP的边界相对于参考点的偏移量和带宽，再加上左右偏移指示，从而确定是左边界还是右边界，从而获得了BWP的频域位置，即BWP的边界位置和带宽。
3)BWP的带宽不是固定的，指示BWP的中心频点位置以及带宽，包括：BWP的中心频点相对于参考点的偏移量以及左右偏移指示，BWP的带宽。具体方法如下：协议预先确定BWP的中心频点相对于参考点的最大偏 移量N，基站根据BWP的中心频点相对于参考点的偏移量、BWP的带宽确定RIV值，然后终端根据收到的RIV值反计算出BWP的中心频点相对于参考点的偏移量以及带宽，再根据获取的左右偏移指示，从而获得BWP的中心频点位置以及带宽。假设最大偏移量为物理载波带宽，用N表示物理载波的带宽为N个RB，用2L表示BWP的带宽为2L个RB(也就是说带宽为偶数个RB)，即BWP带宽的一半为L个RB，用S表示BWP的中心频点相对于参考点的偏移量为S个RB，BWP的中心频点位于参考点的右侧，如图10所示；BWP的中心频点位于参考点的左侧，如图11所示。则RIV占用的比特数为
Figure PCTCN2018098377-appb-000016
RIV的取值为：
RIV＝N(L-1)+S              公式5
终端收到RIV后，计算L和S的值，即
Figure PCTCN2018098377-appb-000017
S＝RIV％N；因此终端根据RIV就可以获得BWP的带宽为
Figure PCTCN2018098377-appb-000018
偏移量为S＝RIV％N，终端获得了S和2L的值，也就获得了BWP的中心频点相对于参考点的偏移量和带宽，再加上左右偏移指示，从而获得了BWP的频域位置。
在实现时，根据实际情况选择对应的方法。
在上述所有实施例中，基站还需要向终端指示Common CORESET的时域位置，以便终端快速接收Common CORESET所承载的信息。所述Common CORESET的时域位置可用其他方法指示，例如，如果Common CORESET是周期发送的，则可以指示发送周期，周期的起始位置所在的无线帧，以及每个发送周期内Common CORESET的起始位置以及持续正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号数。如果是Common CORESET是非周期发送的，则可以指示Common CORESET相对于某个参考位置的时域偏移(例如延迟n个OFDM符号)， 以及持续OFDM符号数。
本实施例给出了一种指示资源位置的方法，包括：第一类节点向第二类节点指示资源的频域位置，包括以下至少一项：指示第一资源的频域位置，指示第二资源的频域位置。其中，第一资源指BWP或者PDSCH占用的资源，第二资源指common CORESET(s)的资源。或者，第一资源指common CORESET(s)的资源，第二资源指BWP或者PDSCH占用的资源，使得基站能够向终端指示BWP、PDSCH以及common CORESET(s)的资源位置，解决了相关技术中基站无法指示BWP、PDSCH以及common CORESET(s)的资源位置的问题。另外，第二资源的频域位置由终端根据预定义则计算，减小了指示开销，且在一定程度上能够减小使用指示的资源传输信息时相邻小区间的相互干扰。另外，联合指示资源带宽的方法也可以降低资源指示的开销。
上述各个实施例中的技术特征，在不冲突的情况下，可以组合在一个实施例中使用。每个实施例仅仅是本申请的最优实施方式。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明实施例的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如随机存取存储器(RAM，Random Access Memory)/只读存储器(ROM，Read-Only Memory)、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例所述的方法。
