在本发明实施例中，发送下行(上行)信道可以是指发送下行(上行)信道上承载的数据或信息，其中，该数据或信息可以是指经过信道编码后的数据或信息。
以控制资源为例，为提高终端设备盲检测效率，NR提出了控制资源集合(Control Resource Set，CORESET)的概念。网络设备为每个终端设备划分一个或多个控制资源集合，并在终端设备对应的任一控制资源集合上，向终端设备发送控制信道。终端设备接入服务小区，获取CORESET在频域上包括的资源块集合(RB set)的信息，所述控制资源集合包括的资源块集合位于一个下行BWP内。NR中进行控制资源分配时，频域上的所述资源块集合分配粒度为连续的6个资源块(RB)。
一般来说，BWP的在频域上占用的资源可以由终端设备的专属信令配置，例如RRC信令，这里并不限定。一个终端设备可最多配置4个BWP用于下行传输，并且还可最多配置4个BWP用于上行传输；且不同终端设备的BWP的配置可以不同，实际传输时只有1个上行/下行BWP被激活以用于传输。带宽区域BWP的资源位于系统载波带宽内，系统载波包括的公共索引区域的物理资源块数量可根据如下表1确定，其中，终端设备接收指示信息确定子载波宽度的指示信息为μ，并根据μ和表1确定公共索引区域的物理资源块的数量；或者接收网络设备的通知以确定，又或者根据标准或者协议的规定确定，这里不做限定，下面以查表的方式为例阐述。
表1
μ 物理资源块的数量
0 275
1 275
2 275
3 275
4 138
5 69
其中，μ对应子载波宽度的大小，如表2所示。例如，μ＝0对应的物理资源块为275，则公共资源块索引(Common RB index)为从编号{0}到编号{274}，即{0,1,2,3,…,274}。所述Common RB index用于配置BWP在频域上所占的资源，其中，一个BWP包括的资源块集合在频域上连续，且在频域上最小粒度为1个资源块。所述Common RB index可以由网络设备配置，对于给定子载波宽度，网络设备配置Common RB index中编号为0的RB相对于频域参考点的偏移量，所述频域参考点为预先配置或定义的、或者网络设备通知(例如，高层信令)的频域位置，其中频域参考点可以为主小区(Pcell,Primiary serving cell，简称Pcell)内同步/广播信道块(Synchronization signal\Physical broadcast channel Block，SS/PBCH Block,Synchronization signal\Physical broadcast channel Block)所包括的编号最小的物理资源块、主小区(Primiary serving cell，Pcell)内由系统信息通知的上行频域位置、辅小区(Secondary serving cell，Scell,Secondary serving cell)内由辅小区配置信息指示的频域位置，以及在辅上行(SUL，Supplement Uplink)频域内由辅上行频域配置信息指示的频域区域中的一种，这里不做具体限定。
表2
μ 子载波宽度
0 15
1 30
2 60
3 120
4 240
5 480
例如，网络设备为两个终端设备UE0和UE1分别配置1个BWP，即BWP0和BWP1，BWP0所在的资源为Common RB index中从RB编号{1}到RB编号{14}的14个频域连续的资源块，即对应Common RB index{1,2,3,4,5,6,7,8,9,10,11,12,13,14}对应的资源块；而BWP1所在资源为Common RB index中RB编号{12}到RB编号{23}的12个频域连续的资源块，即对应Common RB index中RB编号{12,13,14,15,16,17,18,19,20,21,22,23}对应的资源块，如图4所示。BWP0包括的Common RB index为{1,2,3,4,5,6,7,8,9,10,11,12,13,14}，而对应BWP RB index为{0,1,2,3,4,5,6,7,8,9,10,11,12,13}。同理，BWP1对应的BWP RB index也可以从0开始计数。
具体的，网络设备可以配置BWP0为UE0的带宽区域，BWP1为UE1的带宽区域，或者BWP0和BWP1为网络设备为同一个UE配置的两个候选带宽区域，实际场景中还可能存在更多的BWP2、BWP3等，这里不做限定。为了避免不同BWP中的CORESET占用相同RB产生控制信道资源的碰撞问题。进而在BWP0和BWP1以及更多BWP中进行CORESET资源分配时，重叠的RB资源上只配置一个BWP的CORESET资源，下面以图5作为示例性解释。
在图5中，资源指示信息用于指示用于终端设备的多个资源块，可以用位图的方式指 示，位图中的每个比特对应于6个资源块(以RE set的资源分配粒度为6个资源块为例说明)。BWP0包括CORESET0且位图的资源分配指示信息为{`100`}，即CORESET0包括的BWP0的物理资源块编号为{0,1,2,3,4,5}；BWP1包括CORESET1且位图的资源分配指示信息为{`11`}，即CORESET1包括的BWP1的物理资源块编号为{0,1,2,3,4,5,6,7,8,9,10,11}。
由于CORESET0的RB编号{10,11,12,13}与CORESET1中的RB编号{0,1,2,3}对应的Common RB index相同，如图4所示。则在BWP0中，RB编号{10,11,12,13}不能分配给CORESET0，而且，由于CORESET资源分配粒度为6RB，则对应的BWP0中RB编号为{6,7,8,9}的四个RB由于不满足资源分配粒度大小(6个RB)，无法给BWP0中的CORESET0使用，也无法分配给其它BWP使用。因此BWP0中的RB编号{6,7,8,9}成为了资源碎片，导致频谱利用率降低。
由于CORESET在频域上的资源粒度(6RB)与带宽区域在频域上的资源粒度(1RB)不匹配，导致在一个带宽区域内存在无法用于配置CORESET的资源碎片，降低了频谱利用率。数据信道的传输中存在同样的问题。
需要说明的是，本发明实施例涉及术语“起始资源块”，该术语的含义可以是一定区域(例如公共索引区域或者带宽区域)所包括的资源块中对应的子载波编号最小的资源块，或者说是对所包括的资源块从低频向高频方向进行编号时编号最小的资源块；或者，是一定区域(例如公共索引区域或者带宽区域)所包括的资源块中对应的子载波编号最大的资源块，或者说是对所包括的资源块从低频向高频方向进行编号时编号最大的资源块，其中，低频和高频是相对子载波编号定义的，低频位置的子载波编号比高频位置的子载波编号小。实施例中不做具体限定，具体以实际通信系统的要求、网络设备的通知或者标准或者协议的规定为准。
还需要说明的是，本发明实施例涉及“第一个比特”、“第二个比特”、“最后一个比特”等表述，“第一个比特”的含义为多个比特中的最高有效位(Most Significant Bit，简称MSB)，“第二个比特”的含义为多个比特中除所述MSB之外的最高有效位，以此类推。“最后一个比特”的含义为多个比特中的最低位(Least Significant Bit，简称LSB)。本发明实施例采用第一个以及第二个等类似的表述是为了方便进行方案的阐述。
需要说明的是，公共索引区域的起始资源块的频域位置、频域参考点的频域位置、公共索引区域的资源块数量、BWP的起始资源块位置、BWP包含的资源块数量以及子载波宽度之间的任意两个或多个之间可能存在对应关系，所述对应关系可以是标准或协议定义的，也可以是网络设备确定的，或者是网络设备获取的，这里不做具体限定。这些映射关系不影响本发明实施例的实现，本发明实施例涵盖所有的可能。
例如，公共索引区域的起始资源块对于不同子载波宽度，相对于频域参考点的频域位置都相同或者不同；
又如，多个BWP所在的多个公共索引区域的起始资源块在频域上对齐或者不对齐，且所述多个BWP配置的子载波宽度相同或者不相同。
下面将基于上面所述的本发明涉及的共性方面，对本发明实施例进一步详细说明。在实施例的阐述中，忽略上下行可能存在的时延，假设网络设备的发送时刻与终端设备的 接收时刻相同。对于网络设备的发送和终端设备的接收相对应的处理，实施例中多从终端设备侧角度阐述，本领域技术人员可以理解，终端设备从网络设备接收，意味着网络设备进行了发送。本发明中涉及“资源块单元”的表述，本领域技术人员可以理解，所述资源块单元是逻辑上对资源块的划分，便于按照相应的资源分配粒度进行资源配置，可以涵盖其它用于资源块划分的表述。
另外，本发明实施例中各个步骤的编号不限定具体执行过程中的先后顺序，在不同的可选设计中，上述各个步骤执行先后顺序会进行适应性的调整。本发明实施例涉及的用字母来代表的参数的值均为非负整数，即所述字母所指示的值均为非负整数。
实施例1

图6示出了本发明实施例1中通信方法的一种具体实现方式，如下根据图6对本发明的实施例1提供的方案进行说明。
步骤600：网络设备确定多个资源块，所述多个资源块被配置用于第一终端设备；
可选的，所述网络设备还为第二终端设备配置与所述多个资源块部分冲突或者不冲突的多个资源块，后续为了表述方便，将网络设备为其配置了多个资源块的任一个终端设备的表述简化为终端设备。
该确定和/或配置步骤可由网络设备的处理器201执行。
步骤601：所述网络设备向所述终端设备发送资源指示信息，所述资源指示信息用于指示步骤600中的所述多个资源块；
该步骤可以网络设备的收发器202执行，或者由网络设备的处理器201控制收发器202执行。
可选的，所述资源指示信息可以包含多个比特，例如可以为位图(bitmap)。所述多个比特中的每一个比特用于指示至少一个资源块(当所述至少一个资源块为多个资源块时，多个资源块为频域连续的多个资源块)是否用于所述终端设备。具体的，当比特的值为0时，所述比特的值用于指示所述比特对应的至少一个资源块不可用于所述终端设备；当比特的值为1时，所述比特的值用于指示所述比特对应的至少一个资源块可用于所述终端设备。
所述资源指示信息中可以包含多个比特值为1的比特，这些比特所对应的至少一个资源块的集合被配置用于所述终端设备。
这里需要说明的是，所述资源指示信息包含的多个比特的个数以及每个比特对应的至少一个资源块的位置和资源块的个数根据具体的配置方式不同而不同，后文会进行示例性说明，为了阐述方便，所述资源指示信息包含的比特个数称为S，S为正整数。
这里还需要说明的是，网络设备可以为每个终端设备配置多组候选资源块，例如配置多个候选BWP，每个候选BWP中都包含所述终端设备可用的资源块。这里所提到的多个资源块涉及其中一组候选资源块或者所述多个候选BWP中的某一BWP中的资源块，所述终端设备确定通过所述多组候选资源块中的一组资源块向网络设备发送数据信道，或者从网络设备接收或发送控制信道。
可选的，所述资源指示信息为控制资源集合CORESET的频域资源配置信息，例如资源块集合(Resource Block set，RB set)或者，所述资源指示信息为数据资源集合的频域资源配置信息，例如物理上行共享信道PUSCH和/或物理下行共享信道PDSCH的频域资源配置信息。
步骤602，所述终端设备获取资源指示信息，所述资源指示信息指示用于所述终端设备的多个资源块；
该获取步骤可由终端设备的收发器301或者处理器304执行，或者由处理器304控制收发器301执行。
步骤603：所述终端设备确定所述多个资源块的索引信息；
其中，所述索引信息可以为多个资源块在公共索引区域的索引信息，或者在带宽区域的索引信息。
可选的，所述所述多个资源块的索引信息可以为所述多个资源块中的任一个或多个资源块的资源块编号。例如，通过所述多个资源块的起始资源块的索引信息，可以确定所述多个资源块中其它资源块的索引信息；又如，通过所述多个资源块的起始资源块的索引信息，确定所述多个资源块的位置，无需确定所述多个资源块中所有资源块的索引信息。
该确定步骤可由终端设备的处理器304执行。
具体的，所述终端设备确定所述多个资源块的索引信息后，在所述多个资源块上接收所述网络设备发送的控制或数据信道，或者向所述网络设备发送数据信道。
通过上述步骤600-603所实现的通信方法，可以实现网络设备通过资源指示信息通知终端设备分配或重分配的下行或下行资源，使得终端设备可以及时高效的获取所述资源位置，提高终端设备的处理效率。
需要说明的是，本发明实施例1中所涉及的网络设备的确定操作可以通过处理器201执行，网络设备的收发操作可以通过收发器202执行，或者通过处理器201控制收发器202执行；终端设备的确定操作可以通过处理器304执行，终端设备的获取操作可以通过处理器304或者收发器301执行，或者由处理器304控制收发器301执行，具体视获取方式而定，终端设备的收发操作可以通过收发器301执行。
本发明实施例1中，所述用于终端设备的多个资源块的索引可以根据公共索引区域的资源块索引(简称Common RB index)配置，也可以根据带宽区域的资源块索引(简称BWP RB index)配置，具体的配置方式可以由网络设备确定，或者根据标准或协议的规定确定，或者其他方式确定，这里不做具体限定。其中，所述BWP的起始资源块相对于 所述公共索引区域的起始资源块可能存在一定的偏移量，下文中称为第二偏移量。需要说明的是，公共索引区域和BWP区域的资源块索引独立设置时，即分别编号时，公共索引区域的资源块索引和BWP的资源块索引均可以起始资源块为任意数字开始连续编号，例如从0开始或者从1开始等，本发明实施例1不做具体限定，具体实现方式中多以从0开始编号例举。
第一种可选的设计中，所述用于终端设备的多个资源块的索引根据Common RB index配置，该可选的设计中，所述公共索引区域的资源块上配置的一个或多个BWP的索引可以沿用Common RB index，也可以重新定义新的BWP RB index，例如从RB 0开始编号，但是用于所述终端设备的多个资源块的索引是根据Common RB index配置的。
可选的，所述方法还包括步骤6021：所述终端设备获取第一偏移量，所述第一偏移量为公共索引区域的起始资源块与频域参考点之间的偏移量，所述偏移量可以为偏移的RB数量。其中，所述频域参考点的解释参见上文的阐述。不同子载波宽度对应的第一偏移量可能相同或不同，这里不做具体限定。
可选的，终端设备还获取所述公共索引区域的资源块的个数，所述资源块的个数的具体获取方式参见上文中对所述公共索引区域的资源块的个数的阐述，这里不做具体限定，终端设备可以以任何方式获取所述资源块个数。为阐述方便，本发明实施例1称上述公共索引区域的资源块的个数为X1。
可选的，网络设备向所述终端设备发送第一偏移量，所述终端设备从网络设备接收第一偏移量，例如通过高层信令，所述高层信令可以为RRC信令，或者所述终端设备通过预先配置的表格或者对应关系确定所述第一偏移量，所述对应关系可以为第一偏移量与子载波宽度之间的对应关系，或者其他可能用于获取所述第一偏移量的对应关系；或者，所述第一偏移量还可以根据指示或者对应所述第一偏移量的其他值来获取。
可选的，所述第一偏移量可以为RB数目，即所述第一偏移量为公共索引区域的起始资源块相对所述频域参考点偏移的RB数目。
第一种可能的实现中，所述多个资源块的配置以公共索引区域的起始资源块为边界进行对齐。
在该可能的实现中，所述S个比特中第一个比特用于指示所述公共索引区域中从起始资源块开始的n个资源块是否用于所述终端设备。
其中，所述n的值等于m，所述m为资源分配的粒度，可以为预先配置的，或者网络设备确定或者通知给终端设备的，m为正整数。
例如，NR中CORESET在频域上的RB set的分配粒度为连续的6个RB，不足连续6个RB的资源不能用于RB set的资源分配，则m等于6。
参见示例性说明上述资源配置方式的图7，图7根据Common RB index配置所述多个资源块，例如，24个RB，并以公共索引区域的起始资源块作为边界对齐时，所述S个比特中前四个比特分别指示频域上连续的6个RB，且第一个比特指示的为从所述起始资源块开始的连续6个RB。可选的，若所述多个资源块的数量不为6的整数倍，则最后一个资源块单元包含的资源块个数小于6。
又如，针对数据信道的传输，例如物理下行共享信道PDSCH和物理上行共享信道PUSCH的资源配置是以资源块组RBG为分配粒度，但是RBG大小(即每个RBG中包含的RB数)可能与BWP带宽相关，并且每个BWP可能对应多种不同的RBG大小，所述对应关系可以是预先配置的，或者网络设备确定的。可选的，所述对应关系可以以表格的形式体现，例如下表3。所述表中每项对应于一个BWP带宽大小，例如RB数量，每项包含两种REG大小的配置。因此，所述m的值需要根据BWP带宽等相关的参数确定，并且在BWP对应多种RBG大小的情况下，网络设备还需要确定其中的一种RBG大小作为m，并通知给终端设备，所述通知方式可以为高层信令，例如RRC信令。例如，所述，m可以为1、2、4、8、3、6或者12。

可选的，所述S个比特中第二个比特用于指示m个资源块是否用于所述终端设备，所述m个资源块与所述S个比特中第一个比特所指示的n个资源块相邻。
进一步可选的，所述S个比特中第三个比特指示的m个资源块与所述第二个比特所指示的m个资源块相邻。
在该可能的实现中，所述S的值可以为以下的任一种：
第一种，

所述
Figure PCTCN2018095899-appb-000005
代表上取整，所述S个比特中最后一个比特所指示的资源块个数小于m。
通过该可能的实现，可以从公共索引区域的起始资源块开始，连续m个RB作为一个资源块单元进行资源配置。这种配置方式可以实现网络设备以资源块单元边界对齐的方式为多个终端设备配置资源，即，为多个终端设备或多个资源尽量以m个RB为单元进行资源配置，保证终端设备被配置的资源块相对所述起始RB在边界上以m个资源块为资源块单元对齐，或者说，保证终端设备被配置的每个资源块单元的边界与所述起始RB之间偏移的RB数目均为m的倍数，尽量避免出现无法进行分配的资源块碎片(不足m个RB的碎片)，提高了资源利用效率。所述边界可以为所述资源块单元低频和高频边界资源块中的至少一个。
需要说明的是，本发明实施例1中这种资源块单元的划分只是逻辑上的划分，并未在物理资源上体现。
第二种可能的实现中，所述多个资源块的配置以频域参考点为边界进行对齐。
在该可能的实现中，所述S个比特中第一个比特用于指示从所述公共索引区域的起始资源块开始的n个资源块是否用于所述终端设备。其中，所述n的值是根据所述第一偏 移量和m确定的，n大于0，所述m的解释参见上文阐述，这里不再赘述。
可选的，在所述n的值根据所述第一偏移量和m确定的情况下，所述n等于y1，或者n的值等于m减去y1的差值，其中所述y1的值等于第一偏移量与m取模后的值，即:第一偏移量mod m。
第一种可选的实现，当所述第一偏移量为所述起始资源块RB相对于频域参考点向低频方向偏移时，若y1不等于0，则所述n等于y1，若y1等于0，则n等于m减去y1的值。这样使得所述第一个比特指示的为从所述起始RB开始的y1个资源块，从所述第y1+1个资源块开始，尽量以m个RB为资源块单元进行资源配置，以实现所述频域参考点位于逻辑上资源块单元分配的边界。
又如，当所述第一偏移量为所述起始资源块RB相对于频域参考点向高频方向偏移时，所述n的值等于m减去y1的差值，其中所述y1的值等于第一偏移量与m取模后的值，即第一偏移量mod m。这样使得所述第一个比特指示的为从所述起始RB开始的(m-y1)个资源块，该(m-y1)个资源块可以与第一偏移量中的y1个RB的碎片在数量上组成m个资源块的资源块单元，以实现所述频域参考点位于逻辑上资源块单元分配的边界。
可选的，所述S个比特中第二个比特用于指示m个资源块是否用于所述终端设备，所述m个资源块与所述S个比特中第一个比特所指示的n个资源块相邻。
进一步可选的，所述S个比特中第三个比特指示的m个资源块与所述第二个比特所指示的m个资源块相邻。
在该可能的实现中，所述S的值可以为以下的任一种，具体取决于实际通信场景的要求或者配置：

该可能的实现与第一种可能的实现的区别在于对齐位置不同，第一种可能的实现以公共索引区域的起始RB为对齐位置，而第二种可能的实现以频域参考点为对齐位置，但是处理方式类似。
通过该可能的实现，可以实现以频域参考点作为资源块单元配置的边界。这种配置方式可以实现网络设备以资源块单元边界对齐的方式为多个终端设备配置资源，即，以频域参考点作为以m个RB为单元进行资源配置的资源块单元的边界，保证每个终端设备被配置的资源块相对所述频域参考点在边界上以m个资源块为资源块单元对齐，或者说，保证终端设备被配置的每个资源块单元的边界与所述频域参考点之间偏移的RB数目均为m的倍数，尽量避免出现无法进行分配的资源块碎片(不足m个RB的碎片)，提高了资源利用效率。所述边界可以为所述资源块单元低频和高频边界资源块中的至少一个。
第三种可能的实现中，步骤603中所述终端设备确定所述多个资源块的索引信息是通过偏移量指示信息确定。
所述方法还包括步骤6023，所述网络设备向所述终端设备发送偏移量指示信息，所述终端设备获取所述偏移量指示信息，所述偏移量指示信息用于指示资源指示参考资源块相对于公共索引区域的起始资源块偏移的RB数量Q，其中，所述资源指示参考资源块可 以是预先配置或者网络设备确定的，或者是协议或者标准规定的，可以为资源指示信息第一个比特所指示的至少一个资源块中的第一个RB或者最后一个RB，这里的第一个和最后一个或者为低频位置第一个和最后一个，或者为高频位置第一个和最后一个，高频和低频的定义参见上文中的解释。在功能上，所述资源指示参考资源块的配置用于所述终端设备确定所述多个资源块的索引信息。
例如，所述偏移的RB数量Q用于指示从公共索引区域的起始资源块开始向高频方向的连续的Q个资源块，例如，资源块从0开始编号时，公共索引区域的连续Q个资源块RB 0、RB 1……RB m-1。所述Q大于或者等于0，并且小于m，所述m的值参见上文的阐述；
又如，所述资源指示参考资源块为资源指示信息中第一个比特所指示的至少一个资源块中的最后一个RB时，所述S个比特中第一个比特对应从所述起始RB开始的连续Q个资源块，所述Q不为0；
再如，所述资源指示参考资源块为资源指示信息中第一个比特所指示的至少一个资源块中的第一个RB时，若所述Q为0，则所述S个比特第一个比特对应所述公共索引区域的起始资源块开始的连续m个资源块；若所述Q不为0，则所述S个比特的第一个比特对应所述公共索引区域中与从起始资源块开始的连续Q个资源块相邻的m个连续资源块。
进一步可选的，所述S个比特的第二个比特对应于所述公共索引区域内与所述第一个比特所对应的资源块相邻的m个资源块。
可选的，所述偏移指示信息承载于下行控制信息DCI或者高层信令中，由所述网络设备通知给所述终端设备，又或者由网络设备预先通知给所述终端设备，由所述终端设备存储。
进一步可选的，所述偏移指示信息可以为多个比特，所述多个比特所指示的值代表偏移的RB数量，如下表4所示：
表4
偏移量指示信息 偏移量
000 0RB
001 1RB
010 2RB
011 3RB
100 4RB
101 5RB
通过该可能的实现，网络设备向终端设备发送资源指示信息的同时，还向所述终端设备指示所述资源指示信息所指示的部分资源块的位置信息，使得终端设备可以准确高效的获取资源配置信息，提高了终端设备处理效率。
第二种可选的设计中，所述用于终端设备的多个资源块是根据BWP的资源块索引RB index配置的。
可选的，所述方法还包括第一种可选设计中的步骤6021，具体参见上文的阐述。
可选的，所述方法还包括步骤6022，所述终端设备获取第二偏移量，所述第二偏移 量为所述公共索引区域的起始资源块与载波带宽区域BWP的起始资源块之间的偏移量，所述偏移量可以为偏移的RB数量。
可选的，终端设备还获取所述BWP的资源块个数，所述BWP的资源块个数可以查表确定，或者接收网络设备的通知以确定，又或者根据标准或者协议的规定确定，这里不做限定。例如，所述BWP的资源块个数可以通过高层信令，例如RRC信令指示。为阐述方便，本发明实施例1称上述BWP的资源块个数为X2。
进一步可选的，网络设备向所述终端设备发送第二偏移量，所述终端设备从网络设备接收第二偏移量，例如通过高层信令，所述高层信令可以为RRC信令，或者所述终端设备通过预先配置的表格或者对应关系确定所述第二偏移量，所述对应关系可以为第二偏移量与子载波宽度之间的对应关系，或者其他可能用于获取所述第二偏移量的对应关系，或者，所述第二偏移量还可以根据指示或者对应所述第二偏移量的其它值获取，这里不做具体限定。
具体的，所述第二偏移量可以为RB数目，即所述第二偏移量为所述BWP的起始资源块相对于所述公共索引区域的起始资源块偏移的RB数目。
第一种可能的实现中，所述多个资源块的配置以公共索引区域的起始资源块为边界进行对齐。
在该可能的实现中，所述S个比特中第一个比特用于指示带宽区域BWP中从起始资源块开始的连续n个资源块是否用于所述终端设备，或者，所述S个比特中第一个比特用于指示与带宽区域BWP中从起始资源块开始的连续n个资源块相邻的m个资源块是否用于所述终端设备。其中，所述n的值是根据所述m以及所述第二偏移量确定的，n大于0。所述m的解释参见上文中的阐述，这里不再赘述。
由于BWP的频域资源是所述公共索引区域的频域资源的部分或者全部资源块。基于此，所述第二偏移量为所述BWP的起始资源块相对于公共索引区域的起始RB向高频方向的偏移。
具体的，所述n的值等于m减去y2的差值，所述y2的值等于所述第二偏移量与m取模后的值，即：第二偏移量mod m。
可选的，若y2等于0，所述S个比特中第一个比特用于指示带宽区域BWP中从起始资源块开始的连续n个资源块是否用于所述终端设备；
可选的，若y2不等于0，所述S个比特中第一个比特用于指示与带宽区域BWP中从起始资源块开始的连续n个资源块相邻的m个资源块是否用于所述终端设备；
可选的，若y2不等于0，所述S个比特中第一个比特用于指示带宽区域BWP中从起始资源块开始的连续n个资源块是否用于所述终端设备。
参见图8，网络设备为至少一个终端设备配置的BWP0和BWP1均位于公共索引区域的资源块内，所述BWP0的起始位置相对所述公共索引区域的起始资源块向高频方向偏移1个RB，BWP1的起始位置偏移量为4个RB。为了实现以公共索引区域的起始资源块作为资源块单元配置的边界，将所述BWP0的从起始资源块开始RB 0-RB 4前5个RB作为一个资源块单元，RB 5-RB 10作为一个资源块单元，以此类推。这样可以保证BWP中第二个资源块单元的起始资源块RB 5相对于所述公共索引区域的起始资源块偏移的RB数量为6的整数倍，同样，BWP0中第三个资源块单元的起始资源块RB 11相对于所述公共索引区 域的起始资源块偏移的RB数量也为6的整数倍。同理，BWP1的RB 0-RB 1作为一个资源块单元。在这种实现下，即使网络设备配置的BWP0和BWP1，可能还有更多的BWP，由于每个资源块单元的起始或者最后一个资源块相对于所述公共索引区域的起始资源块RB的偏移的RB数量均为m的整数倍，在所述多个BWP的重叠部分，也能够保证出现尽可能少的资源碎片。
可选的，所述S个比特中第二个比特用于指示m个资源块是否用于所述终端设备，所述m个资源块与所述S个比特中第一个比特所指示的n个资源块相邻。
进一步可选的，所述S个比特中第三个比特指示的m个资源块与所述第二个比特所指示的m个资源块相邻。
在该可能的实现中，所述S的值可以为以下的任一种：

通过该可能的实现，可以实现以公共索引区域的起始资源块作为资源块单元配置的边界。这种配置方式可以实现网络设备以资源块单元边界对齐的方式为多个终端设备配置资源，即，以m个RB为单元进行资源配置，保证终端设备被配置的资源块相对所述起始RB在边界上以m个资源块为资源块单元对齐，或者说，保证终端设备被配置的每个资源块单元的边界与所述起始RB之间偏移的RB数目均为m的倍数，尽量避免出现无法进行分配的资源块碎片(不足m个RB的碎片)，提高了资源利用效率。所述边界可以为所述资源块单元低频和高频边界资源块中的至少一个。
第二种可能的实现中，所述多个资源块的配置以频域参考点为边界进行对齐。
在该可能的实现中，所述S个比特中第一个比特用于指示带宽区域BWP中从起始资源块开始的连续n个资源块是否用于所述终端设备，或者，所述S个比特中第一个比特用于指示与带宽区域BWP中从起始资源块开始的连续n个资源块相邻的m个资源块是否用于所述终端设备，所述n的值是根据所述m以及第三偏移量确定的，n大于0，所述m的解释参见上文阐述，这里不再赘述。
可选的，所述n等于y3，或者，等于m与y3的差值，其中所述y3的值等于第三偏移量与m取模后的值，所述第三偏移量与所述第一和第二偏移量有关。具体的，所述第三偏移量为所述BWP的起始资源块与所述频域参考点之间的偏移量。可替代的，所述第三偏移量还可以根据指示或者对应所述第三偏移量的其他值来获取，而并非根据第一和第二偏移量确定。
进一步可选的，所述第三偏移量可以为偏移的RB数量，即所述第三偏移量为所述BWP的起始资源块相对所述频域参考点偏移的RB数。
例如，当所述第三偏移量为所述BWP的起始资源块RB相对于频域参考点向低频方向偏移时，所述n等于y3，或者等于m减去y3的值，其中所述y3的值等于第三偏移量与m取模后的值，即第三偏移量mod m。这样使得所述第一个比特指示的为从所述BWP的起始资源块开始的y3个资源块，从所述第y3+1个资源块开始，尽量以m个RB为资源块单元进行资源配置，以实现所述频域参考点位于逻辑上资源块单元分配的边界。
在这种情况下：
可选的，若y3不等于0，则n等于y3，所述S个比特中第一个比特用于指示带宽区域BWP中从起始资源块开始的连续n个资源块是否用于所述终端设备，或者，所述S个比特中第一个比特用于指示与带宽区域BWP中从起始资源块开始的连续n个资源块相邻的m个资源块是否用于所述终端设备；
可选的，若y3等于0时，n等于m减去y3的值，即等于m本身；所述S个比特中第一个比特用于指示带宽区域BWP中从起始资源块开始的连续n个资源块是否用于所述终端设备。
又如，当所述第三偏移量为所述BWP的起始资源块相对于频域参考点向高频方向偏移时，所述n的值等于m减去y3的差值，即(m-y3)，其中所述y3的值等于第三偏移量与m取模后的值，即第三偏移量mod m。这样使得所述第一个比特指示的为从所述BWP的起始资源块开始的(m-y3)个资源块，该(m-y3)个资源块可以与第三偏移量中的y3个RB的碎片在数量上组成m个资源块的资源块单元，以实现所述频域参考点位于逻辑上资源块单元分配的边界。
在这种情况下：
可选的，若y3等于0，所述S个比特中第一个比特用于指示带宽区域BWP中从起始资源块开始的连续n个资源块是否用于所述终端设备；
可选的，若y3不等于0，所述S个比特中第一个比特用于指示带宽区域BWP中从起始资源块开始的连续n个资源块是否用于所述终端设备，或者，所述S个比特中第一个比特用于指示与带宽区域BWP中从起始资源块开始的连续n个资源块相邻的m个资源块是否用于所述终端设备。

例如，所述偏移的RB数量Q用于指示从公共索引区域的起始资源块或者所述BWP的起始资源块开始的连续的Q个资源块；例如公共索引区域或者BWP起始资源块开始的连续Q个资源块RB 0、RB 1……RB m-1。所述Q大于或者等于0，并且小于m，所述m的值参见上文的阐述。
又如，所述资源指示参考资源块为资源指示信息中第一个比特所指示的至少一个资源块中的最后一个RB时，所述S个比特中第一个比特对应从所述公共索引区域或者BWP起始资源块起始资源块开始的连续Q个资源块，所述Q不为0。
再如，所述资源指示参考资源块为资源指示信息中第一个比特所指示的至少一个资源块中的第一个RB时，所述S个比特第一个比特对应所述公共索引区域或BWP的起始资源块开始的连续m个资源块，所述Q为0。
其中，由于该可选的设计中，所述网络设备根据BWP的资源块索引RB index配置用于所述终端设备的资源块。当所述偏移量指示信息指示从公共索引区域的起始资源块开始的连续的Q个资源块时，所述终端设备通过所述偏移量指示信息和所述第二偏移量确定所述多个资源块的索引信息。
进一步可选的，所述S个比特的第二个比特对应于所述公共索引区域或者BWP内与所述第一个比特所对应的资源块相邻的m个资源块。
可选的，所述偏移指示信息承载于下行控制信息DCI或者高层信令中，由所述网络设备通知给所述终端设备，又或者由网络设备预先通知给所述终端设备，由所述终端设备存储。

例如，所述Common起始资源块的RB编号为0，则所述BWP的起始资源块的在所述公共索引区域中的编号为(0+第二偏移量)。
由于BWP的频域资源是所述公共索引区域的频域资源的部分或者全部资源块。基于此，所述第二偏移量为所述BWP的起始资源块相对于所述Common index scheme的起始资源块向高频方向的偏移。
具体的，所述n的值等于m减去y2的差值，所述y2的值等于所述第二偏移量与m取模后的值，即：第二偏移量mod m。关于y2的值与S个比特中第一个比特位所指示的资源块位置之间存在的可选的对应关系，可以参考第二种可选的设计中的第一种可能的实现中的阐述。

进一步可选的，所述第三偏移量可以为偏移的RB数量，即所述第三偏移量为所述BWP的起始资源块R0相对所述频域参考点偏移的RB数。
例如，当所述第三偏移量为所述BWP的起始资源块相对于频域参考点向低频方向偏移时，所述n等于y3，或者等于m减去y3的值，其中所述y3的值等于第三偏移量与m取模后的值，即第三偏移量mod m。这样使得所述第一个比特指示的为从所述BWP的起始资源块开始的y3个资源块，从所述第y3+1个资源块开始，尽量以m个RB为资源块单元进行资源配置，以实现所述频域参考点位于逻辑上资源块单元分配的边界。
