通过设置RBG offset的粒度为RBG_S，从而使得基站的资源分配更加简单，降低了网络设备资源分配的复杂度。也可以降低终端计算的复杂度。当S’的粒度第三RBG的大小为RBG_S，可以进一步降低基站资源分配和终端计算的复杂度；当S’的粒度为RB时，第二频域位置可以从任一RB开始，更有利于资源合理分配。

N为第一BWP中包括的RB的总数，第一BWP包括第一频域资源和第二频域资源，或者说第一BWP是第一数据所在的BWP。RBG offset即为第一频域偏置值。
通过设置RB offset的粒度为RBG_L，与L的粒度进行了统一，使得相邻两次跳频的间隔是RBG_L的整数倍，如此使得频域资源能够实现连续分配，避免频域资源的浪费。并且每一跳的频域资源开始位置通过RB编号指示，也即开始位置可以从任一RB开始，更有利于资源的合理分配。

通过如上任一种RIV与S和L的公式设计，使得RIV所需的比特数相对于现有技术有效降低，也即频域资源指示的比特数有效降低，从而提高了PDCCH的可靠性。且RIV与S和L是一一对应的，因此终端设备确定的频域资源与网络设备侧实际指示的频域资源一致，避免了后续数据通信的失败。

Z为频域资源映射表的行数，该实现方式下频域资源索引所需的比特数为log 2Z，网络设备可以根据通信的实际情况，设计一个行数比较小的频域资源映射表，如此在保证通信灵活性的同时，还可以达到降低DCI比特数的效果，提高数据通信的可靠性。

通过设置RBG offset的粒度为RBG_S，从而使得基站的资源分配更加简单，降低了网络设备资源分配的复杂度。也可以降低终端计算的复杂度。当S’的粒度第三RBG的大小为RBG_S，可以进一步降基站低资源分配和终端计算的复杂度；当S’的粒度为RB时，第二频域位置可以从任一RB开始，更有利于资源合理分配。

2、网络设备。本申请实施例中网络设备是一种为终端设备提供无线通信功能的设备，也可称之为无线接入网(radio access network，RAN)设备等。网络设备包括但不限于：5G中的下一代基站(next generation nodeB，gNB)、演进型节点B(evolved node B，eNB)、基带单元(baseband unit，BBU)、收发点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、中继站、接入点等。网络设备还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器、集中单元(centralized unit，CU)、分布单元(distributed unit，DU)等。其中，网络设备可以支持至少一种无线通信技术，例如LTE、NR、WCDMA等。
3、终端设备与网络设备之间的通信。本申请实施例中终端设备和网络设备是通过无线接口(radio interface)进行通信的。
4、上行通信。本申请实施例中上行通信又可以称之为上行传输，指的是在终端设备与网络设备之间的通信中，终端设备向网络设备发送信号的过程。其中，终端设备向网络设备发送的信号可以称为上行信号或上行信息。示例的，上行信号包括上行控制信息(uplink control information，UCI)和上行数据。上行控制信息用于承载终端设备反馈的相关信息，例如信道状态信息(channel state information，CSI)、确认应答(acknowledgement，ACK)/否认应答(negative acknowledge，NACK)等。具体的，上行控制信息可以承载在物理上行控制信道(physical uplink control channel，PUCCH)上，也可以承载在物理上行共享信道(physical upnlink shared channel，PUSCH)上；上行数据可以承载在PUSCH上。
5、下行通信。本申请实施例中下行通信又可以称之为下行传输，指的是在终端设备与网络设备之间的通信中，终端设备接收网络设备发送的信号的过程。其中，终端设备接收网络设备发送的信号可以称为下行信号或下行信息。示例的，下行信号可以包括DCI和下行数据(downlink data)。下行控制信息是用于下行数据调度的相关信息，例如，数据信道的资源分配、调制编码方式等信息。具体的，DCI可以承载在PDCCH上，下行数据可以承载在物理下行共享信道(physical downlink shared channel，PDSCH)上。
上行数据的通信和/或下行数据的通信也可以被称为数据通信。
6、载波带宽部分。本申请实施例中的载波带宽部分可以简称为带宽部分(bandwidth part，BWP)，指的是载波上一段连续或非连续的频域资源，其中，这段连续或非连续的频域资源的带宽不超过终端设备的带宽能力，即BWP的带宽小于或等于终端设备支持的最大带宽。以BWP为载波上一段连续的频域资源为例，BWP可以是载波上一组连续的资源块(resource block，RB)，或者BWP是载波上一组连续的子载波，或者BWP是载波上一组连续的资源块组(resource block group，RBG)等。其中，一个RBG中包括至少一个RB，例如1个、2个、4个、8个或16个等，一个RB可以包括至少一个子载波，例如12个等。
本申请实施例中终端设备与网络设备通信所使用的BWP，可以是网络设备配置的，还可以是协议预定义的，该协议可以是第三代合作伙伴计划项目(the 3 rd generation partnership project，3GPP)。对于一个终端设备来说，网络设备可以为终端设备在一个载波内配置一个或多个BWP。例如，如图2(a)所示，网络设备为终端设备在一个载波内配置了一个BWP。其中，BWP的带宽不超过终端设备的带宽能力，且BWP的带宽不大于载波带宽。再例如，如图2(b)所示，网络设备为终端设备在一个载波内配置了两个BWP，分别为BWP1和BWP2， 其中，BWP1与BWP2存在重叠。又例如，如图2(c)所示，网络设备为终端设备在一个载波内配置了两个BWP，分别为BWP1和BWP2，其中BWP1和BWP2完全不重叠。需要说明的是，本申请实施例中网络设备为终端设备配置的BWP的个数不是无限制的。举例来说，网络设备为终端设备最多可以配置4个BWP。再例如，在频分双工(frequency division duplexing，FDD)的场景下，网络设备可以为终端设备的上、下行通信分别配置4个BWP。又例如，在时分双工(time division duplexing，TDD)的场景下，网络设备可以为终端设备的上、下行通信分别配置4个BWP。
此外，网络设备可以针对每个BWP，为终端设备配置系统参数。本申请实施例中，不同的BWP对应的系统参数可以相同，也可以不同。以图2(b)为例，BWP1对应的系统参数和BWP2对应的系统参数可以相同，也可以不同。
8、时隙(slot)。本申请实施例中的slot可以理解为在时域上的一段时间。一个slot的时长可以与子载波间隔的大小相关，不同大小的子载波间隔对应的slot的时长是不同的。例如，子载波间隔为15kHz时，一个时隙的时长可以为1毫秒(millisecond，ms)；子载波间隔为30kHz时，一个时隙的时长可以为0.5ms。示例的，本申请实施例中一个时隙可以包括一个或多个符号。比如，正常(normal)循环前缀(cyclic prefix，CP)下，一个时隙可以包括14个符号；扩展(extended)CP下，一个时隙可以包括12个符号。
9、RBG的大小(RBG size)。本申请实施例中RBG的大小可以指一个RBG中包含的RB的个数，它是一种衡量上行数据或者下行数据所占的频域资源大小的单位。例如，一个RBG中包含了4个RB，可以理解为RBG的大小为4个RB。也就是说以4个RB为单位进行频域资源的分配，上行数据信道或者下行数据信道所占的频域资源中包含的RB个数为4的整数倍。
关于指示频域资源的方式，一种可能的方法为：网络设备通过将资源指示值(resource indicator value，RIV)承载在DCI中发送给终端设备，指示一段频域资源。上行数据或下行数据所使用的频域资源至少包括了该段频域资源，或者说承载上行数据或下行数据的数据信道所使用的频域资源至少包括了该段频域资源。其中如前所述，该数据信道可以为PDSCH，或者PUSCH，分别对应承载下行数据和上行数据。该RIV的取值与该频域资源的开始位置S、该频域资源的长度L相关。具体的，可以通过如下公式(1)计算得出：
当
Figure PCTCN2020106486-appb-000035
时，RIV＝N*(L RBs-1)+RB start；
当
Figure PCTCN2020106486-appb-000036
时，RIV＝N*(N-L RBs+1)+(N-1-RB start)公式(1)
其中，N为BWP包括的RB个数，N为正整数。当S的粒度为RB时，RB start即为S，表示频域开始位置的资源块RB的编号，RB start为大于等于0的整数。L RBs即为L，表示频域连续RB的个数。1≤L RBs≤N-RB start，且L为整数。在本申请中，如果没有特别说明，BWP可以是上行BWP也可以下行BWP。
终端设备通过网络设备发送的RIV获得S和L，通过S和L，即可以唯一确定该频域资源。
举例来说，假设N＝10，RB start＝0，L RBs＝5，则根据上面的公式(1)，RIV＝40。网络设备在DCI中承载的RIV＝40，终端设备可以根据RIV＝40得出，开始位置S为RB0，长度为5个RB，也即图3所示的RB0至RB4为所要指示的频域资源。
采用该种频域资源的指示方法，RIV所需的比特数为
Figure PCTCN2020106486-appb-000037
当N较大时，RIV所需的比特数会变的很多，因此数据通信的可靠性，特别是超可靠低时延通信(ultra-reliable and low-latency communication，URLLC)场景下数据通信的可靠性，无法 得到很好的保证。为此，可以通过改变S和L的粒度来对以上方法进行优化获得第二种频域资源指示方式。其中，粒度指一种数据单位，在下文本申请实施例中将会详细解释。可以通过将以上方法中S和L的粒度从RB改到资源块组(resource block group，RBG)。S可以表示频域资源开始位置的RBG编号，L表示频域上连续的RBG的个数。则RIV可以通过如下公式(2)得出：
设
Figure PCTCN2020106486-appb-000038
若
Figure PCTCN2020106486-appb-000039
则RIV＝N1*(L-1)+S；
否则，RIV＝N1*(N1-L+1)+(N1-S-1)     公式(2)
其中，为L为≥1的整数，S为≥0的整数，且L+S≤N1，
Figure PCTCN2020106486-appb-000040
表示向下取整。
采用该种频域资源的指示方法，RIV所需的比特数为
Figure PCTCN2020106486-appb-000041
由于N1＝N/RBG siz，公式(2)相对于公式(1)，RIV所需要的比特数有效地降低了，即DCI中的频域资源指示域的比特数降低了，从而能够提高DCI的可靠性。
但是如上第二种频域资源指示方式中，L和S的粒度是一致的，以RBG size是4个RB为例，也就是说只能以4个RB为粒度分配资源：开始位置S的RB编号只能是4的整数倍(例如，RB0，RB4，或者RB8)；L指示的长度也只能是4个RB的整数倍。此时，假设N不是4的整数倍，则会出现有些RB永远无法被分配，出现资源浪费的情况。例如，假设下行BWP为10个RB，分别为RB0至RB9，则只有RB0至RB7可能被分配出去，RB8和RB9永远无法被使用。
基于如上的问题，可以通过分别配置S和L的粒度来对第二种频域资源指示方式进行优化获得第三种频域资源指示方式，以提高资源的合理利用率。由于S和L的粒度可以不同，这里将S的粒度对应的RBG大小记为RBG_S，将L的粒度对应的RBG大小记为RBG_L，那么RIV的计算方式可以分为如下两种情况：情况一：
Figure PCTCN2020106486-appb-000042
情况二：N2＝N/RBG_S。这两种情况N的取值不同，但是，都可以使用如下公式(3)：
若
Figure PCTCN2020106486-appb-000043
则RIV＝N2*(L-1)+S；
否则，RIV＝N2*(N2-L+1)+(N2-S-1)       公式(3)
其中，各个参数还需要满足：L*RBG_L+S*RBG_S≤N。
公式(3)中RIV所需的比特数为
Figure PCTCN2020106486-appb-000044
通过如上方式，可以有效解决某些RB无法被分配的问题，但是仍会导致新的问题产生。
例如对于情况一:设N为8个RB，RBG_L＝2个RB，RBG_S＝1个RB，则得到的RIV与S和L的对应关系如表1所示：
表1
L\S 0 1 2 3 4 5 6
1 0 1 2 3 4 5 6
2 4 5 6 7 8    
3 8 9 10        
4 7            
由于S的取值范围为0至
Figure PCTCN2020106486-appb-000045
的整数，L的取值范围为0至
Figure PCTCN2020106486-appb-000046
的整数。第一行取值代表S的可选值为0至6，第一列取值代表L的可选值1至4。因为还需要 满足L*RBG_L+S*RBG_S≤N，所以不满足该需求的S和L的组合(即表1中未填写RIV值所对应的S和L的组合)被进一步去除。需要说明的是，后续采用与表1类似的方法对表格2至表格5进行绘制，故后续相关部分不再赘述。
可以看出其中RIV的取值有很多重复的，例如，S＝4，L＝1时，RIV是4；S＝0，L＝2时，RIV还是等于4，也就是说RIV与S和L不是一一对应的，这就导致了频域资源指示出现模糊，网络设备和终端设备对于RIV可能出现不同的解读，当网络设备向终端设备指示RIV＝4时，终端设备无法判断此时是指示的是S＝4，L＝1，还是S＝0，L＝2。终端设备确定的频域资源与网络设备侧实际指示的频域资源不一致时，就会造成后续数据通信的失败。
又例如对于情况二：假设N为8个RB，RBG_L＝2个RB，RBG_S＝1个RB，则得到的RIV与S和L的对应关系如表2所示，
表2
L\S 0 1 2 3 4 5 6
1 0 1 2 3 4 5 6
2 8 9 10 11 12    
3 16 17 18        
4 47            
在表2中虽然可以看出其中RIV的取值与S和L是一一对应的，但是频域资源指示值RIV的最大值为47，如果要指示这个47，则需要6比特。但是即便是退回到第一种频域资源指示方式，即采用公式(1)计算RIV值，在相同的N的情况下，获得的RIV所需的比特数只有5比特，比特数不仅没有降低，还出现了增加，无法保证DCI的可靠性。
因此，需要使用一种新的频域资源指示方式，不仅能够使得RIV与S和L之间是一一对应的，而且还可以有效降低RIV的比特数。
实施例一
本申请实施例提供了一种频域资源指示方法，可以应用于图1所示的通信场景。该方法可以有效降低RIV的比特数、提高数据通信的可靠性。如图4所示，该方法可以包括：
S401、网络设备向终端设备发送RIV，该RIV用于指示第一频域资源的开始位置S和长度L，所述第一频域资源为第一数据所使用的部分或全部频域资源；其中，所述S的粒度为第一RBG，所述L的粒度为第二RBG，所述第一RBG的大小为RBG_S，所述第二RBG的大小为RBG_L。其中，所述S和所述RIV为大于等于零的整数，所述L、所述RBG_S和所述RBG_L为正整数。
对应的，终端设备接收来自网络设备的RIV。
S402、终端设备根据该RIV，确定该第一频域资源。
S403、终端设备在第一频域资源上向所述网络设备发送所述第一数据，或在所述第一频域资源上接收来自所述网络设备的第一数据。
这里终端设备向网络设备发送的第一数据即为上行数据；终端设备接收的来自网络设备的第一数据即为下行数据。它们都可以理解为终端设备和网络设备所交互的数据。第一数据可以承载于PDSCH上，或者承载于PUSCH上。可以理解的是，S403的具体方式是 本领域技术人员所熟悉知晓的，因此本申请不加赘述。
当本申请实施例不应用于跳频场景下时，该第一频域资源即为第一数据所使用的全部频域资源。当本申请实施例应用于跳频场景或者是第一数据重复发送的场景下时，该第一频域资源即为第一数据所使用的部分频域资源。关于跳频的详细介绍，将在本申请之后结合具体技术方案做详细介绍，可供此处参照。
RIV的物理意义与作用和前面所介绍的类似。可以通过设计新的公式来确定RIV与S和L之间的关系，并使得RIV达到如上所述的有益效果。
在S401中提到的S的粒度，与前文提及的概念一致，可以理解为S的单位。进一步的，所述S的粒度为第一RBG，可以理解为S的数据单位为第一RBG，也就是说这里S的值，可以是某段频域范围内的RBG编号。例如，第一RBG的大小RBG_S为4个RB，那么当S＝1时，代表了所述第一频域资源的开始位置的第一RBG编号为1，对应的RB编号为4；当S＝2时，代表了所述第一频域资源的开始位置的第二RBG编号为2，对应的RB编号为8。可以以同样的方式理解L的粒度，即为L的数据单位。所述L的粒度为第二RBG，可以理解为L的数据单位为第二RBG。例如第二RBG的大小RBG_L为8个RB，那么当L＝1时，代表了所述第一频域资源的长度为1个第二RBG，也就是8个RB；当L＝2时，代表了所述第一频域资源的长度为2个第二RBG，也就是16个RB。
当将S和L的粒度为RBG时，S可以表示频域资源开始位置的RBG编号，S还可以记做RBG start；L表示频域上连续的RBG的个数，还可以记做L RBGs。
需要说明的是RBG_S和/或RBG_L可以是根据第一数据所在的BWP包含的RB个数确定的。RBG_S和RBG_L可以由网络设备分别通过高层信令中的第一指示信息和第二指示信息发送给终端设备。该第一指示信息和第二指示信息可以位于同一条高层信令中，也可以位于不同的高层信令中。在本申请的各个实施例中，高层信令具体可以为媒体接入控制(medium access control，MAC)信令，或者无线资源控制(radio access control，RRC)信令等。RBG_S和/或RBG_L还可以替换为使用协议预定义的方式使终端设备获知。
进一步的，S401中，RIV的取值可以与RBG_S和/或RBG_L相关。下面通过如下具体实现方式1.1至实现方式1.3，结合S401对该特征进行具体介绍：
首先需要说明的是，如下实现方式1.1至实现方式1.3中：
N为第一BWP中包括的RB的总数，第一BWP包括第一数据所使用的频域资源，因为第一频域资源为第一数据所使用的部分或者全部频域资源，也即第一BWP包括了第一频域资源。或者说第一BWP是第一数据所在的BWP，也就是前文所述的上行BWP或下行BWP。所述L的取值范围为1至
Figure PCTCN2020106486-appb-000047
且L和S满足L*RBG_L+S*RBG_S≤N。
需要说明的是，之所以要使得L和S满足L*RBG_L+S*RBG_S≤N，是为了确保以此确定出来的第一频域资源位于第一BWP内。基于S的物理含义、以上L的取值范围和该不等式，还可以对S至少做出如下的限定：S的取值范围为
Figure PCTCN2020106486-appb-000048
实现方式1.1：通过如下公式(4)计算得出RIV：
当L等于1时，RIV等于S；
当L大于1时，
Figure PCTCN2020106486-appb-000049
其中，
Figure PCTCN2020106486-appb-000050
i是整数，且2≤i≤L。
进一步地，举一具体例子。设N＝8，RBG_S＝1个RB，RBG_L＝2个RB，则根据公式(4)，可以获得RIV与S和L的对应关系，如下表3所示：
表3
L\S 0 1 2 3 4 5 6
1 0 1 2 3 4 5 6
2 7 8 9 10 11    
3 12 13 14        
4 15            
从表3中可以看出所有RIV的取值在整数范围是连续的，也即，RIV的最小值和最大值范围内的所有整数(包括RIV的最小值、最大值)都能找到与其对应的S和L。同时RIV的最小值为0。此时RIV所需的比特数为
Figure PCTCN2020106486-appb-000051
S和L的有效组合个数满足L*RBG_L+S*RBG_S≤N的所有可能的S和L组成的组合。此时，RIV所需的比特数为
Figure PCTCN2020106486-appb-000052
小于采用公式(1)计算得出的比特数6。这种优势，在N较大时更加明显。由于RIV所需比特数降低，从而保证了DCI的可靠性较高。同时，通过表3可以发现，采用本实现方式，RIV与S和L是一一对应的，因此终端设备确定的频域资源与网络设备侧实际指示的频域资源一致，避免了后续数据通信的失败。
可选的，还可以从另外一种角度对本实现方式中RIV与S和L的对应关系进行表述。例如，通过计算机执行的伪代码表示出RIV与S和L之间的关系：
Figure PCTCN2020106486-appb-000053
实现方式1.2：通过如下公式(5)计算得出RIV：
Figure PCTCN2020106486-appb-000054
当
Figure PCTCN2020106486-appb-000055
时，RIV＝N_S*(L-1)+S；
当
Figure PCTCN2020106486-appb-000056
时，RIV＝N_S*(N_L-L+1)+(N_S-S-1)；      公式(5)
进一步地，举一具体例子。
设N＝10，RBG_S＝1个RB，RBG_L＝2个RB，则根据公式(5)，可以获得RIV与S和L的对应关系，如下表4所示：
表4
L\S 0 1 2 3 4 5 6 7 8
1 0 1 2 3 4 5 6 7 8
2 9 10 11 12 13 14 15    
3 18 19 20 21 22        
4 26 25 24            
5 17                
从表4中可以看出，此时RIV值与S和L是一一对应的，因此终端设备确定的频域资源与网络设备侧实际指示的频域资源一致，避免了后续数据通信的失败。此时RIV取值范围为0到26，因此，对应的RIV所述的比特数为5比特。而此时若使用公式(1)获得的RIV所需的比特数为6比特，因此降低了RIV指示所需的比特数，进一步提高了数据通信的可靠性。同时，通过表4可以发现，采用本实现方式，RIV与S和L是一一对应的，因此终端设备确定的频域资源与网络设备侧实际指示的频域资源一致，避免了后续数据通信的失败。
实现方式1.3：通过如下公式(6)计算得出RIV：
设
Figure PCTCN2020106486-appb-000057
当
Figure PCTCN2020106486-appb-000058
时，RIV＝N_L*(L-1)+S+offset1；
当
Figure PCTCN2020106486-appb-000059
时，RIV＝N_L*(N_L-L+1)+(N_L-S-1)+offset2；    公式(6)
其中，offset1和offset2为偏置值，其目的是为了避免产生例如使用前述公式(3)进行频域资源指示时可能发生的RIV与S和L不一一对应，也就是说避免了网络设备和终端设备对于频域资源指示值RIV可能出现不同的解读而造成后续数据通信的失败。
可选的，所述offset1和offset2的取值可以相同也可以不同，可以由网络设备通过高层信令中的第三指示信息和第四指示信息发送给终端设备。该第三指示信息和第四指示信息可以位于同一条高层信令中，也可以位于不同的高层信令中。当然，offset1和offset2中的至少一个还可以替换为使用协议预定义的方式使终端设备获知。
若offset1和offset2采用预定义的方式使得终端获知，在一种实现方式中，可以预定义offset1＝offset2＝(N_L-N_S)*(L-1)。将offset1和offset2的值带入公式(6)，此时本实现方式中的公式(6)进一步转换为(7)：
Figure PCTCN2020106486-appb-000060
当
Figure PCTCN2020106486-appb-000061
时，RIV＝N_L*(L-1)+S+(N_L-N_S)*(L-1)
当
Figure PCTCN2020106486-appb-000062
时，RIV＝N_L*(N_L-L+1)+(N_L-S-1)+(N_L-N_S)*(L-1)    公式(7)
此时举一具体例子。
设N＝8，RBG_S＝1个RB，RBG_L＝2个RB，则根据公式(7)，可以获得RIV与S和L的对应关系，如下表5所示：
表5
L\S 0 1 2 3 4 5 6
1 0 1 2 3 4 5 6
2 9 10 11 12 13    
3 18 19 20        
4 22            
从表5中可以看出，此时RIV值与S和L是一一对应的，因此终端设备确定的频域资源与网络设备侧实际指示的频域资源一致，避免了后续数据通信的失败。同时RIV所需的比特数也相对较小，可以获得与以上实施方式类似的有益效果。
需要说明的是，可以灵活地对S和L的粒度进行配置，使得RBG_S和RBG_L不同或者相同。特别的，为了降低终端设备的实现复杂度，更合理的利用资源可以进一步的使得RBG_S和RBG_L相同。此时，可以将S和L的粒度统一记为P，即RBG_S＝RBG_L＝P。P为正整数。
在此基础上，有如下实现方式1.4：
通过如下公式(8)得出：
若
Figure PCTCN2020106486-appb-000063
则RIV＝N2*(L-1)+S；
否则，RIV＝N2*(N2-L+1)+(N2-S-1)      公式(8)
其中，N2代表了第一BWP中的以P进行划分的RBG个数，N2还可以记为N RBG。L表示频域上连续的RBG的个数，所以L＝1,…,N RBG。S可以表示频域资源开始位置的RBG编号，所以S＝0,1,…,N RBG-1。L+S≤N2，
Figure PCTCN2020106486-appb-000064
表示向下取整。
下面对N2的计算方式进行说明：N2是根据第一BWP包括的RB总数N，以及P确定的：
Figure PCTCN2020106486-appb-000065
其中，在第一BWP的N2个RBG中，第一个RBG的大小为
Figure PCTCN2020106486-appb-000066
Figure PCTCN2020106486-appb-000067
最后一个RBG的大小为
Figure PCTCN2020106486-appb-000068
如果(N+N)mod P>0，则
Figure PCTCN2020106486-appb-000069
否则，
Figure PCTCN2020106486-appb-000070
在第一BWP中的其它的RBG的大小为P。
需要说明的是按照如上的计算方式，第一BWP中将最多包括三种RBG大小，本申请实施例中可以将除第一个RBG大小以及最后一个RBG大小外的其它RBG大小定义为第一BWP上S和L的粒度，也就是说将网络设备通过指示信息指示的P值定义为S和L的粒度。
例如，如图5所示，第一BWP中包括的RB个数为11个RB，假设P＝4个RB，则可以确定N2＝4。即该BWP中有4个RBG，其中第一个RBG的大小为1个RB，最后一个(第四个)RBG的大小为2个RB，中间的2个RBG(第二个RBG和第二个RBG)大小都是4RB。进一步的，如果通过RIV指示频域资源的S＝0，L＝2，即第一频域资源从第1个RBG开始，长度为2个RBG，即图中灰色部分所示。
通过实现方式1.4，频域资源指示域的比特数从公式(1)需要的
Figure PCTCN2020106486-appb-000071
比 特减小到了
Figure PCTCN2020106486-appb-000072
比特。N2小于N，从而节省了控制信令的开销，保证了通信的可靠性。
通过上述实现方式1.1至1.4，S402中终端设备可以通过接收来自网络设备发送的RIV，确定出第一频域资源的S和L，进而根据S和L确定该第一频域资源。需要说明的是终端设备根据RIV结合如上任一公式推算S和L的方式类似于现有技术中根据RIV，结合公式(1)推算S和L的方式，本领域技术人员是熟悉知晓的，因此本申请不再赘述。
实施例二
上述实施例沿用RIV指示S和L，但采用新的RIV与S和L的关系公式的方式解决现有技术中的缺陷。。本申请实施例还提供了一种新的方式对S和L进行指示的频域资源指示方法，可以应用于图1所示的通信场景。该方法同样可以有效降低DCI的比特数、提高数据通信的可靠性。如图6所示，该方法可以包括：
S501、网络设备向终端设备发送频域资源索引，所述频域资源索引用于指示第一频域资源的开始位置S和长度L，所述第一频域资源为第一数据所使用的部分或全部频域资源；其中，所述S的粒度为第一资源块组RBG，所述L的粒度为第二RBG，所述第一RBG的大小为RBG_S，所述第二RBG的大小为RBG_L；所述S为大于等于零的整数，所述L、所述RBG_S和所述RBG_L为正整数。
对应的，终端设备接收来自网络设备的频域资源索引。
S502、终端设备根据所述频域资源索引，确定所述第一频域资源。
S503、终端设备在第一频域资源上向所述网络设备发送所述第一数据，或在所述第一频域资源上接收来自所述网络设备的第一数据。S503的具体实现方式可以参考实施例一中的S403，这里不加赘述。
第一数据、第一频域资源、S的粒度为第一RBG以及L的粒度为第二RBG的定义可以参考实施例一中的表述。RBG_S和/或RBG_L的确定以及终端设备获得RBG_S和/或RBG_L的方式也可以参考实施例一中相关部分的表述，因此不加赘述。
本实施例中，网络设备通过向终端设备发送频域资源索引来指示第一频域资源的S和L。而该频域资源索引与S和L的关系，包含在一张频域资源映射表中。该频域资源映射表中的每一行可以指示一个S和一个L的值，该频域资源索引可以指向频域资源映射表中的某一行。终端设备根据网络设备发送的频域资源索引，结合该频域资源映射表即可获得所述第一频域资源的S和L。该频域资源索引可以包含在DCI中由网络设备发送给终端设备。
终端设备获取该频域资源索引的方式可以包括如下两种实现方式。需要说明的是，如下实现方式2.1中，i为正整数，所述L(i)的取值范围为1至
Figure PCTCN2020106486-appb-000073
且所述L(i)和所述S(i)满足L(i)*RBG_L+S(i)*RBG_S≤N。可选的，对S(i)进一步限定：所述S(i)的取值范围为0至
Figure PCTCN2020106486-appb-000074
实现方式2.1：
该频域资源映射表是预定义的。也即可以在协议中预定义该频域资源映射表，那么终端设备即可获知。
可选的，该频域资源表格的每一行从上到下可以按照所有可能的L值从小到大的顺序 排列，相邻两行的L值不变时，所有可能的S值按照从小到大的顺序排列。也就是说，所述频域资源指示表中第i行对应频域资源的开始位置和长度分别记为S(i)和L(i)，且第i行对应的频域资源索引为i；
所述频域资源指示表满足：
L(i+1)>L(i)；或者
L(i+1)＝L(i)时，S(i+1)>S(i)
进一步地，举一具体例子。
设N＝8，RBG_S＝1个RB，RBG_L＝2个RB，则由此设计出的频域资源表格如表6所示。
表6
Figure PCTCN2020106486-appb-000075
可选地，该表6中可以没有频域资源索引这一列，此时所述频域资源索引按照表格的第一行开始从上到到下依次编号。
可选的，该频域资源表格的每一行从上到下可以按照所有可能的S值从小到大的顺序排列，S值不变时，所有可能的L值按照从小到大的顺序排列。也就是说，所述频域资源指示表中第i行对应频域资源的开始位置和长度分别记为S(i)和L(i)，且第i行对应的频域资源索引为i；
所述频域资源指示表满足：
S(i+1)>S(i)；或者
S(i+1)＝S(i)时，L(i+1)>L(i)
进一步地，举一具体例子。
设N＝8，RBG_S＝1个RB，RBG_L＝2个RB，则由此设计出的频域资源表格如表7所示。
表7
Figure PCTCN2020106486-appb-000076
可选地，该表7中可以没有频域资源索引这一列，此时所述频域资源索引按照表格的第一行开始从上到到下依次编号。
从表6和表7可以看出，本实施例的频域资源索引与S和L是一一对应的，因此网络设备和终端设备对频域资源索引所指示的S与L理解是一致的。同时，该频域资源索引所需的比特数为
Figure PCTCN2020106486-appb-000077
S和L的有效组合为满足L*RBG_L+S*RBG_S≤N的所有可能的S和L组成的组合，其所需的比特数与实施例一实现方式一是一样的，因此可以达到与其类似的有益效果。
实现方式2.2：
该频域资源映射表为网络设备通过信令指示给终端设备的，具体可以通过高层信令指示给该终端设备。相比于本实施例实现方式一，网络设备可以根据实时的通信情况确定该频域资源映射表中的S和L，更加的灵活。
例如，网络设备通过信令指示的频域资源映射表包含了Z行。每一行对应一个S的可能取值和一个L的可能取值。若频域资源索引为大于等于零的整数，那么该频域资源索引加1 就代表了取第几行对应的S和L。此时的频域资源映射表可以如表8所示。
表8
Figure PCTCN2020106486-appb-000078
Z为频域资源映射表的行数，该实现方式二下频域资源索引所需的比特数为log 2Z，网络设备可以根据通信的实际情况，设计一个行数比较小的频域资源映射表，如此在保证通信灵活性的同时，还可以达到降低DCI比特数的效果，提高数据通信的可靠性。
通过上述各种实现方式，S502中终端设备可以通过接收来自网络设备发送频域资源索引，查表获得第一频域资源的S和L，进而根据S和L确定该第一频域资源。
需要说明的是，在实施例二中，频域资源映射表仅为一种实现方式。实际可以不限于表格的方式，也可以为集合的方式，或者清单(list)的方式。
当某一段频域资源对应的信道条件不佳时，如果将所有的数据都调度在该频域资源上进行收发，将导致数据通信错误的概率大大增加。因此现有技术中，支持将数据通信的资源在频域上分散开，这样将有效降低信道条件差的某一段频域资源对整个数据通信的影响。也就是说，可以通过如上方式获得频域分集增益。获得频域分集增益的一种具体实现方式为跳频。举例来说，如果没有跳频，原来在某一时间段内用于数据通信的频域资源为RB0至RB7，共8个RB；如果采用跳频技术，那么可以将该时间段分为时间上相邻的两个时间段：时间段一和时间段二，在时间段一为RB0至RB7，而在时间段二用于数据通信的频域资源变为RB80至RB87，从而获得了频域分集增益。在本申请中，RBn表示索引为n的RB，例如这里的RB0、RB7、RB80和RB87分别表示索引为0、7、80和87的RB。
进一步的，对于上行通信的跳频，具体包括slot内跳频和slot间跳频。
一、slot内跳频：
对于一个slot内的数据传输，仅支持两跳。DCI中指示的时域资源长度为K，该时域资源为上行通信的数据所使用的时域资源。可以将K分为两部分，第一部分长度为
Figure PCTCN2020106486-appb-000079
第二部分为
Figure PCTCN2020106486-appb-000080
在频域上，每一跳的开始位置S’可以根据公式(9)确定。
Figure PCTCN2020106486-appb-000081
其中，RIV指示的频域资源的开始位置S即为RB start，RB start为≥0的整数，N为上行BWP的RB个数。第一跳(first hop)RB start的位置就是RIV中指示的开始位置，第二跳(second hop)的开始位置RB start为第一跳位置加上一个频率偏移RB offset。其中RB offset的取值可以通过配置信息和DCI综合确定。例如终端设备接收网络设备发送配置信息，该配置信息配置多个RB offset的取值，在DCI中包含一个指示域，指示该多个RB offset中的一个取值即为第二跳时的RB offset。
举例来说，DCI指示时域资源长度为8，例如，为符号1到符号8，共8个符号。RIV指示开始位置S为RB0，指示RB offset为4个RB。则第一跳使用的时域资源为符号1到符号4，使用的频域开始位置为RB0，第二跳使用的时域资源符号为5到8，使用的频域开始位置为RB4。
二、slot间跳频：
对于在多个连续slot内的数据传输，支持每一个slot一跳。具体如下面的公式(10)所示:
Figure PCTCN2020106486-appb-000082
其中，RIV指示的频域资源的开始位置S即为RB start，RB start为≥0的整数，N为下行BWP的RB个数。
Figure PCTCN2020106486-appb-000083
是时隙的编号。如公式(9)，
Figure PCTCN2020106486-appb-000084
时，即编号为偶数的时隙对应的频域开始位置S就是DCI中RIV指示的开始位置。
Figure PCTCN2020106486-appb-000085
时，即编号为奇数的时隙对应的频域开始位置S’则需要加频域偏置RB offset。具体RB offset的确定方式如slot内跳频中所述，不再赘述。
三、上行数据多次重复发送的跳频：
对于在多次上行重复发送，支持每一次重复一跳。这里此时RB start(i)也可以称为第i+1次上行数据重复发送对应的频域资源的开始位置。设K为上行数据总的重复次数，则n的取值范围为0至K-1的整数。此时，不限于slot间的跳频。具体如下面的公式(11)所示:
Figure PCTCN2020106486-appb-000086
需要说明的是，对于重复发送的含义，举例来说，若为第0次上行数据重复发送，执行完该次发送，则代表上行数据重发发送了一次，若为第5次上行数据重复发送，执行完该次发送，则代表上行数据重发发送了六次，且每次发送的数据内容相同。
若RIV指示的开始位置S和长度L以RBG为粒度分别设置时，在slot内跳频或者slot间跳频时，终端设备如何准确地确定每一跳的开始位置，成为需要解决的问题。
实施例三
本实施例提供了一种跳频指示的方法，可以应用于图1所示的通信场景。该方法可以使得终端设备准确确定跳频时每一跳的频域开始位置，保证网络设备侧和终端对上行数据的频域位置有一致的理解。如图7所示，该方法包括：
S601、网络设备向终端设备发送第一频域偏置值，所述第一频域偏置值指示第二频域资源的开始位置S’与第一频域资源的开始位位置S在频域上的间隔，所述第一频域偏置值的粒度为第三RBG。
对应的，终端设备接收来自所述网络设备的第一频域偏置值
S602、终端设备确定所述第二频域资源。
这里所述的第一频域资源，即为实施例一或者二中所定义的第一频域资源。进一步的，在跳频场景下，第一频域资源为第一数据的第一跳对应的频域资源，第二频域资源为第一数据的第二跳对应的频域资源。需要说明的是，在跳频场景下，第一频域资源即为第一数据所使用的部分频域资源，第一数据所使用的频域资源应该还至少包括第二频域资源。
此处跳频既可以为slot内的跳频，也可以为slot间的跳频。对slot间的跳频，第一跳对应的频域资源可以理解为偶数slot编号下对应的频域资源，第二跳对应的频域资源可以理解为奇数slot编号下对应的频域资源。
本实施例中第一跳的S的粒度可以是第一RBG，且第一RBG的大小为RBG_S。第一频域资源的L的粒度可以是第二RBG，且第二RBG的大小为RBG_L。
下面具体介绍S602中，终端设备确定第二频域资源的实现方式。
需要说明的是本实施例中，N为第一BWP中包括的RB的总数，第一BWP包括第一频域资源和第二频域资源，或者说第一BWP是第一数据所在的BWP。RBG offset即为第一频域偏置值。RBG offset的确定方式可以与前述提及的slot内跳频中RB offset确定方式类似，不再赘述。
实现方式3.1：
S601中第一频域偏置值的粒度为第三RBG，且第三RBG的大小为RBG_S。
情况一：
若此时S’具体指的是第二跳的频域资源开始位置的RBG编号，也即S’的粒度为第四RBG，且第四RBG的大小为RBG_S。那么终端设备可以通过如下公式(12)确定S’:
S’＝(S+RBG offset)mod N’      公式(12)
其中，N’为
Figure PCTCN2020106486-appb-000087
进一步参照公式(9)和(10)，进行更完整的公式表述。需要说明的是，以下S”为第i+1跳对应的频域资源的开始位置(以RBG编号指示)。
1)Slot内跳频：
Figure PCTCN2020106486-appb-000088
2)Slot间跳频：i为slot在无线帧内的编号。
Figure PCTCN2020106486-appb-000089
还可以将上述跳频技术方案扩展应用到上行重复发送的场景。
3)例如，终端设备在进行上行通信时，不仅仅可以支持slot内跳频和slot间跳频，还可以支持上行数据重复发送的跳频场景(此时不限于slot间的跳频)。这里此时S”也可以称为第i+1次上行数据重复对应的频域资源的开始位置。设K为上行数据总的重复次数，则i的取值范围为0至K-1的整数。
Figure PCTCN2020106486-appb-000090
对于重复发送的含义，举例来说，如果上行数据重复发送5次，则代表，所述上行数据被发送了5次，且每次发送的数据内容相同。
4)又例如，还可以支持上行数据多次重复发送，且第i+1次重复发送的频域资源的起始位置相对于第i次重复发送的频域资源的起始位置固定相差RBG offset的跳频场景。此时S”也可以称为第i+1次上行数据重复对应的频域资源的开始位置。K为上行数据总的重复次数，则i的取值范围为0至K-1的整数。
Figure PCTCN2020106486-appb-000091
情况一下，通过设置RBG offset的粒度为RBG_S，通过这个方式可以使得每一跳的频域资源的开始位置对应的编号粒度相同，从而使得基站的资源分配更加简单，降低了网络设备资源分配的复杂度，也可以降低终端计算的复杂度。
情况二：
若此时S’具体指示的是第二跳的频域资源开始位置的RB编号，那么终端设备可以通过如下公式(17)确定S’:
S’＝(S*RBG_S+RBG offset*RBG_S)mod N      公式(17)
进一步参照公式(9)和(10)，进行更完整的公式表述。需要说明的是，S”为第i+1次跳频时对应的频域资源的开始位置(以RB编号指示)。
1)Slot内跳频：
Figure PCTCN2020106486-appb-000092
2)Slot间跳频：i为slot在无线帧内的编号。
Figure PCTCN2020106486-appb-000093
3)类似的，上行数据多次重复发送的场景下，S”也称为第i+1次上行数据重复对应的频域资源的开始位置。设K为上行数据总的重复次数，则i的取值范围为0至K-1的整数。
Figure PCTCN2020106486-appb-000094
4)上行数据多次重复发送，且第i+1次重复发送的频域资源的起始位置相对于第i次重复发送的频域资源的起始位置固定相差RBG offset的跳频场景下，此时S”也称为第i+1次上行数据重复对应的频域资源的开始位置。K为上行数据总的重复次数，则i的取值范围为0至K-1的整数。
Figure PCTCN2020106486-appb-000095
情况二下，通过设置RBG offset的粒度为RBG_S，有利于与S的指示统一，降低终端计算的复杂度。并且每一跳通过S”具体指示的是频域资源开始位置的RB编号，更有利于资源的合理分配。
实现方式3.2：
S601中第一频域偏置值的粒度为第三RBG，且第三RBG的大小为RBG_L。
若此时S’具体指示的是第二跳的频域资源开始位置的RB编号，那么终端设备可以通过如下公式(20)确定S’:
S’＝(S*RBG_S+RBG offset*RBG_L)mod N      公式(22)
进一步参照公式(9)和(10)，进行更完整的公式表述。需要说明的是，S”为第i+1次跳频时对应的频域资源的开始位置(以RB编号指示)。
1)Slot内跳频：
Figure PCTCN2020106486-appb-000096
2)Slot间跳频：i为slot在无线帧内的编号。
Figure PCTCN2020106486-appb-000097
3)类似的，上行数据多次重复发送的跳频场景下，此时S”也称为第i+1次上行数据重复对应的频域资源的开始位置(以RB编号指示)。设K为上行数据总的重复次数，则i的取值范围为0至K-1的整数。
Figure PCTCN2020106486-appb-000098
4)上行数据多次重复发送、且第i+1次重复发送的频域资源的起始位置相对于第i次重复发送的频域资源的起始位置固定相差RBG offset的跳频场景。此时S”也称为第i+1次上行数据重复对应的频域资源的开始位置。K为上行数据总的重复次数，则i的取值范围为0至K-1的整数。
Figure PCTCN2020106486-appb-000099
实现方式二中，通过设置RB offset的粒度为RBG_L，与L的粒度进行了统一，使得相邻两次跳频的间隔是RBG_L的整数倍，如此使得频域资源能够实现连续分配，避免频域资源的浪费。并且每一跳的频域资源开始位置通过RB编号指示，更有利于资源的合理分配。
实现方式3.3
当RBG_S＝RBG_L＝P时，S601中第一频域偏置值的粒度为第三RBG，且第三RBG的大小为P。即第一偏置值的粒度和S、L的粒度相同。
若此时S’具体指的是第二跳的频域资源开始位置的RBG编号，开始RBG编号可以记为RBG start，即S’的粒度为P，那么终端设备可以通过如下公式(27)确定S’:
S’＝(S+RBG offset)mod N2      公式(27)
其中，N2和S可以根据前述的实施例一的实现方式1.4示方式确定，不再赘述。
进一步参照公式(9)和(10)，进行更完整的公式表述。
1)Slot内跳频场景下，第i+1跳的开始RBG为：
Figure PCTCN2020106486-appb-000100
则i等于0代表第一跳对应的频域资源的开始位置，即第一频域资源的开始位置，i＝1代表第二跳对应的频域资源的开始位置即第一频域资源的开始位置。
2)Slot间跳频，slot i中的开始RBG为：
Figure PCTCN2020106486-appb-000101
则i mod 2＝0代表第一跳对应的频域资源的开始位置即第一频域资源的开始位置，也就是偶数个时隙内的频域资源的开始位置，i mod 2＝1代表第二跳对应的频域资源的开始位置即第二频域资源的开始位置，也就是奇数个时隙内的频域资源的开始位置。
3)上行数据多次重复发送的跳频，第i次重复发送的开始RBG为：
Figure PCTCN2020106486-appb-000102
则i mod 2＝0代表第一跳对应的频域资源的开始位置，即第一频域资源的开始位置，也就是偶数次重复发送对应的频域资源的开始位置，i mod 2＝1代表第二跳对应的频域资源的开始位置即第二频域资源的开始位置，也就是奇数次重复发送对应的频域资源的开始位置。
在上述各个实施例中，S″和S均可以记为RBG start。
通过设置RBG offset的粒度为RBG，通过这个方式可以使得每一跳的频域资源的开始位置对应的编号粒度相同，从而使得基站的资源分配更加简单，降低了网络设备资源分配的复杂度，也可以降低终端计算的复杂度。
需要说明的是，本实施例中定义的i值，虽然起始值为0，但也不排除起始值可以从1或者其它数值开始，且本领域技术人员无需通过创造性劳动即可直接对上述涉及i的公式做出相应的变换。本实施例可以单独于实施例一和实施例二，还可以和实施例一和实施例二中任一实施例进行结合，构成更为完整的通信方案，本申请不做限制。
S602中，终端设备在根据以上公式(12)至(31)中的任意一个确定出S’或S”之后，结合前述的实施例一的实现方式1.4示方式L的取值，便可确定出第二跳时对应的第二频域资源(或者后续某一跳时对应的频域资源)。随后，终端设备可以在第二频域资源上向网络设备发送第一数据，从而实现第一数据的跳频传输。
特别的，在实现方式3.3中，第二频域资源(或者称为第二跳、奇数次时隙或者第奇数次重复发送的频域资源)的长度L’的取值有如下2种方式：
方式a：L’＝L,所述L以P为粒度，则所述L’也以P为粒度。即每一跳的频域资源长度占用的RBG个数都相同，都是RIV值指示的L的粒度的大小。如实施例一实现方式1.4中所述，实际中第一BWP中包括的N2个RBG的大小可能不同，因此每一跳对应的频域资源包括的RB个数可能是不同的。
例如，第一BWP中，N＝11个RB,如实施例一实现方式1.4中图5对应的示例，N2＝4，即有4个RBG，其中第一个RBG为1个RB，其中第二个RBG和第三RBG为2个RB，其中第四个RBG为2个RB。假设RIV指示S＝0，L＝2，则第一频域资源包括的RBG个数为2个RBG。假设RBG offset＝1个RBG,则第一频域资源和第二频域资源均包括2个RBG，分别如图8中灰色的格子和划竖线的格子所示。
方式b：
L’＝L,所述L以P为粒度，则所述L’也以P为粒度。第二频域资源长度L ′可以根据第二频域资源对应的S”以及第一频域资源实际包括的RB个数确定。其中第一频域资源实际包括的RB个数为根据S和L确定出的RB的个数。例如，通过实施例一实现方式1.4，第一BWP中N2个RBG中每个RBG包含的RB个数可以确定出来，因此可以根据RIV指示的S和L确定出第一频域资源包括的RB个数。
具体来说，根据第二频域资源对应的S”以及第一频域资源实际包括的RB个数确定L’的方式为：确定参考频域资源，该参考频域资源为从第S”开始、连续包括第一频域资源实际包括的RB个数。如果参考频域资源的结束RB位置在N2个RBG中的第j个RBG内部，而非第j个RBG的开始RB,或者第j个RBG的结束RB，则该第二频域资源为从S”对应的RBG开始到第j个RBG结束，或者到第j-1个RBG结束。若参考频域资源的结束RB即为第j个RBG的结束RB，那么第二频域资源为从S”对应的RBG开始到第j个RBG结束。j为小于等于N2的正整数。
例如，第一BWP中，N＝11个RB,如实施例一实现方式1.4中图5对应的示例，N2＝4，即有4个RBG，其中第一个RBG为1个RB，第二个RBG和第三RBG为4个RB，第四个RBG为2个RB。假设RIV指示S＝0，L＝2，则第一频域资源包括第一个RBG和第二个RBG。L＝2个RBG，则第一频域资源实际包括的RB个数为5个RB。假设RBG offset＝1个RBG,对应第二频域资源对应的起始RB为第二个RBG的起始RB：第二个RB，则确定第三频域资源为从第二个RB开始，连续5个RB。第三频域资源的结束RB位置在第3个RBG内，即第三频域位置的结束RB位置不是第3个RBG的开始RB,也不是第3个RBG的结束RB，则该第二频域资源位置为从第二个RBG开始开始，到第3个RBG结束(如图9划横线的位置)，或者从第二个RBG开始，到第2个RBG结束(如图9划竖线的位置)。
实施例四
本实施例提供了一种跳频指示的方法，可以应用于图1所示的通信场景。该方法可以使得终端设备准确确定跳频时每一跳的频域开始位置，保证网络设备侧和终端对上行数据的频域位置有一致的理解。如图10所示，该方法包括：
S701、网络设备向终端设备发送第二频域偏置值，所述第二频域偏置值指示第二频域资源的开始位置S’与第一频域资源的开始位位置S在频域上的间隔，所述第二频域偏置值的粒度为RB。
对应的，终端设备接收来自所述网络设备的第二频域偏置值
S702、终端设备确定所述第二频域资源。
本实施例中所指的第一频域资源和第二频域资源的含义已经在实施例三种进行了阐 述，因此不再重复。同样的，本实施例中第一跳的S的粒度可以是第一RBG，且第一RBG的大小为RBG_S。
下面具体介绍702中，终端设备确定第二频域资源的实现方式。
需要说明的是本实施例中，N为第一BWP中包括的RB的总数，第一BWP包括第一频域资源和第二频域资源，或者说第一BWP是第一数据所在的BWP。RB offset即为第二频域偏置值，其粒度为RB。RB offset的确定方式可以参照slot内跳频中RB offset所述，不再赘述。
实现方式4.1：
若此时S’具体指示的是第二跳的频域资源开始位置的RBG编号，S’的粒度为第四RBG，第四RBG的大小为RBG_S。那么终端设备可以通过如下公式(32)确定S’:
Figure PCTCN2020106486-appb-000103
其中，N’为
Figure PCTCN2020106486-appb-000104
进一步参照公式(9)和(10)，进行更完整的公式表述。需要说明的是，S”为第i+1次跳频时对应的频域资源的开始位置(以RBG编号指示)。
1)Slot内跳频：
Figure PCTCN2020106486-appb-000105
2)Slot间跳频：i为slot在无线帧内的编号。
Figure PCTCN2020106486-appb-000106
还可以将上述跳频技术方案扩展应用到上行重复发送的场景。
3)例如，终端设备在进行上行通信时，
不仅仅可以支持slot内跳频和slot间跳频，还可以支持上行数据重复发送的跳频场景(此时不限于slot间的跳频)，此时S”也可以称为第i+1次上行数据重复对应的频域资源的开始位置。设K为上行数据总的重复次数，则i的取值范围为0至K-1的整数。
Figure PCTCN2020106486-appb-000107
4)又例如，还可以支持上行数据多次重复发送、且第i+1次重复发送的频域资源的起始位置相对于第i次重复发送的频域资源的起始位置固定相差RB offset的跳频场景。，此时S”也可以称为第i+1次上行数据重复对应的频域资源的开始位置。K为上行数据总的重复次数，则i的取值范围为0至K-1的整数。
Figure PCTCN2020106486-appb-000108
实现方式一中RB offset的粒度为RB，可以保证后向兼容性。并且保证了终端设备和网 络设备对RB offset理解一致，同时每一跳具体指示的是频域资源开始位置的RBG编号，与S保持一致，可以降低频域资源分配算法的复杂度。
实现方式4.2：
若此时S’具体指示的是第二的跳频域资源开始位置的RB编号，那么终端设备可以通过如下公式(30)确定S’:
S’＝(S*RBG+RB offset)mod N      公式(37)
进一步参照公式(9)和(10)，进行更完整的公式表述。需要说明的是，S”为第i+1次跳频时对应的频域资源的开始位置(以RB编号指示)。
1)Slot内跳频：

3)类似的，上行数据多次重复发送的跳频场景下，此时S”也称为第i+1次上行数据重复对应的频域资源的开始位置。设K为上行数据总的重复次数，则i的取值范围为0至K-1的整数。

4)上行数据多次重复发送、且第i+1次重复发送的频域资源的起始位置相对于第i次重复发送的频域资源的起始位置固定相差RB offset的跳频场景。此时S”也称为第i+1次上行数据重复对应的频域资源的开始位置。K为上行数据总的重复次数，则i的取值范围为0至K-1的整数。
Figure PCTCN2020106486-appb-000112
进一步的，如下实施例基于实施例一的实现方式1.4：
若此时RB start具体指的是第一跳的频域资源开始位置的RB编号，那么终端设备可以通过公式(9)到公式(11)确定每一跳的频域开始位置:
此时RB start可以根据S以及N2个RBG中每个RBG的RBG个数确定。例如，根据实施例一实现方式1.4确定第一BWP中各个RBG包含的RB数以及各个RBG的起始RB，根据S找到对应的RBG，则该RBG的起始RB即为RB start。
RB offset可以由网络设备发送指示信息向终端设备指示，为了保证资源利用率，该RB offset可以是P的整数倍。即RB offset＝C*P,其中C为正整数。
或者，可以配置RB offset具有多个候选值。候选值至少包括下面的一个：N2个RBG中第一个RBG中的RB个数、N2个RBG中最后一个RBG中的RB个数、N2个RBG中 剩余RBG中RB个数(即P)的整数倍，以及是第一个RBG的RB个数与剩余RBG中RB个数(即P)的整数倍之和。
此时S701中网络设备向终端设备发送第二频域偏置值具体为，网络设备向终端设备发送第二频域偏置值集合，该集合中至少包括下面的一个：N2个RBG中第一个RBG中的RB个数、N2个RBG中最后一个RBG中的RB个数、N2个RBG中剩余RBG中RB个数(即P)的整数倍，以及是第一个RBG的RB个数与剩余RBG中RB个数(即P)的整数倍之和。网络设备进而通过发送第五指示信息指示第二频域偏置值集合中的一个值从而指示第二频域偏置值。
终端设备接收第二频域偏置值集合和第五指示信息，从而确定出第二频域频域偏置值。
实现方式二中RB offset的粒度为RB，可以保证后向兼容性。并且保证了终端设备和网络设备对offset理解一致。
需要说明的本实施例可以单独于实施例一至实施例二，还可以和实施例一和实施例二中任一实施例进行结合，构成更为完整的通信方案，本申请不做限制。
S702中，终端设备根据以上公式(32)至(41)中的任意一个确定出S’或S”之后，结合L的取值，便可确定出第二跳时对应的第二频域资源(或者后续某一跳时对应的频域资源)。
第二频域资源的长度L’的取值方式可以参见实施例三中相关的表述，此处不再赘述。
随后，终端设备可以在第二频域资源上向网络设备发送第一数据，从而实现第一数据的跳频传输。
上述本申请提供的实施例中，从网络设备和终端设备作为执行主体的角度对本申请实施例提供的通信方法进行了介绍。为了实现上述本申请实施例提供的通信方法中的各功能，终端设备和网络设备可以包括硬件结构和/或软件模块，以硬件结构、软件模块、或硬件结构加软件模块的形式来实现上述各功能。上述各功能中的某个功能以硬件结构、软件模块、还是硬件结构加软件模块的方式来执行，取决于技术方案的特定应用和设计约束条件。
