图1中的网络设备可以为接入网设备，例如基站。其中，接入网设备在不同的系统对应不同的设备，例如在第四代移动通信技术(the 4 th generation，4G)系统中可以对应eNB，在5G系统中对应5G中的接入网设备，例如gNB。尽管在图1中仅示出了终端设备120、终端设备130和终端设备140，应理解，网络设备可以为多个终端设备提供服务，本申请实施例对通信系统中终端设备的数量不作限定。同理，图1中的终端设备是以手机为例进行说明的，也应理解，本申请实施例中的终端设备不限于此。
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)终端设备，又可称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备。所述终端设备可以经无线接入网(radio access network，RAN)与核心网进行通信，与RAN交换语音和/或数据。例如，终端设备可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端设备的示例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备、虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
2)网络设备，是网络中用于将终端设备接入到无线网络的设备。所述网络设备可以为无线接入网中的节点，又可以称为基站，还可以称为无线接入网(radio access network，RAN)节点(或设备)。网络设备可用于将收到的空中帧与网际协议(IP)分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。网络设备还可协调对空口的属性管理。例如，网络设备可以包括长期演进(long term evolution，LTE)系统或演进的LTE系统(LTE-Advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括第五代移动通信技术(5th generation，5G)新无线(new radio，NR)系统中的下一代节点B(next generation node B，gNB)，或者还可以包括传输接收点(transmission reception point，TRP)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或WiFi接入点(access point，AP)等，再或者还可以包括云接入网(cloud radio access network，CloudRAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，本申请实施例并不限定。
3)带宽部分(bandwidth part，BWP)，一个BWP在频域上包括若干个连续的资源块(resource block，RB)，该RB可以为物理资源块(physical resource block，PRB)，如图2所示，一个PRB包括频域上连续的K个子载波，K可以为12。在LTE系统中，一个资源块包括12个子载波，在5G NR系统中，一个资源块也包括12个子载波。随着通信系统的演进，一个资源块中包括的子载波的数量也可以是其他值，本申请并不限定。
4)上行数据信道，用于承载上行数据信息。例如为物理上行共享信道(physical uplink shared channel，PUSCH)，或者为增强的物理上行共享信道(enhanced physical uplink control channel，EPUSCH)，或者可以是其他的上行数据信道。在本文中，上行数据信道是以PUSCH为例进行介绍的。
5)本申请实施例中的术语“系统”和“网络”可被互换使用。“多个”是指两个或两个以上，鉴于此，本申请实施例中也可以将“多个”理解为“至少两个”。“至少一个”，可理解为一个或多个，例如理解为一个、两个或更多个。例如，包括至少一个，是指包括一个、两个或更多个，而且不限制包括的是哪几个。例如，包括A、B和C中的至少一个，那么包括的可以是A、B、C，A和B，A和C，B和C，或A和B和C。同理，对于“至少一种”等描述的理解，也是类似的。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。
除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词，用于区分多个对象，但不用于限定多个对象的顺序、时序、优先级或者重要程度，并且“第一”、“第二”的描述也并不限定对象一定不同。
请参考图3，为本申请实施例提供的一种通信方法的流程示意图。该方法包括如下的步骤S301至步骤S304：
步骤S301、网络设备向终端设备发送第一消息，该第一消息用于指示终端设备在N个子载波上向网络设备发送上行数据信号。
本申请实施例中，上行数据信号承载在上行数据信道上，例如可以是PUSCH，所述N个子载波为PUSCH占用的子载波，即用于发送上行数据信号的子载波。但应注意的是，这N个子载波分布在M个资源块(resource block，RB)中，且只占用M个RB中每个RB中的部分子载波，M为大于等于2的正整数。也就是说，M个RB中的每个RB中用于发送上行数据信号的子载波的数量为L，L小于K，K为一个RB中包括的子载波的个数，例如K可以是12。
可以理解，M个RB中的每个RB包括连续的K个子载波，但只有其中的L个子载波用于发送上行数据信号。鉴于此，本申请实施例中，第一消息还可以用于指示M个RB中的每个RB中用于发送上行数据信号的L个子载波，给出PUSCH到L个子载波的映射方式。
一种可能的映射方式为，每个RB包括的子载波按照从0到K-1的顺序编号，其中，该RB中用于发送上行数据信号的L个子载波在该RB中的编号具体为s，s+S，…，s+(L-1)*S。这里，S为步长，S＝K/L，S可以大于等于2，s为小于S的非负整数，s+(L-1)*S小于等于K-1。
例如，S的值可以为2、3、4、6、8、12。作为一种示例，图4示出了s＝0，且S分别为2、3、4、6时用于发送上行数据信号的子载波的分布。如图4所示，一个RB中包括 12个子载波，S＝2时，PUSCH占用一个RB中的6个子载波即L＝6，这6个子载波在图4中用实线表示，按照步长2间隔排列，其余的6个子载波用虚线表示。S＝3时，PUSCH占用一个RB中的4个子载波即L＝4，这4个子载波在图4中用实线表示，按照步长3间隔排列，其余的8个子载波用虚线表示。S＝4时，PUSCH占用一个RB中的3个子载波即L＝3，这3个子载波在图4中用实线表示，按照步长4间隔排列，其余的9个子载波用虚线表示。S＝6时，PUSCH占用一个RB中的2个子载波即L＝2，这2个子载波在图4中用实线表示，按照步长6间隔排列，其余的10个子载波用虚线表示。
由图4可知，PUSCH可占用一个RB中的部分子载波，且PUSCH占用的子载波在RB中不连续排列。若将非连续的K个子载波称为一个离散资源块(discrete resource block，DRB)，那么在采用该子载波的映射方式时，PUSCH占用的一个DRB可由S个RB中用于发送上行数据信号的子载波组成。若将DRB关联的RB的个数记做DRB的度，此时DRB的度为S。因此，图4中分别示出了S＝2、S＝3、S＝4、S＝6时PUSCH占用的一个DRB，S不同时，DRB关联的RB的个数也不同，即DRB的度也不同。其中，S＝2时，一个DRB由2个RB中用于发送上行数据信号的子载波组成，DRB的度为2；S＝3时，一个DRB由3个RB中用于发送上行数据信号的子载波组成，DRB的度为3；S＝4时，一个DRB由4个RB中用于发送上行数据信号的子载波组成，DRB的度为4；S＝6时，一个DRB由6个RB中用于发送上行数据信号的子载波组成，DRB的度为6。需要说明的是，此处的DRB和度仅是为了方便指代，并不对名称进行限定。
再例如，当步长S为一设定值，但s的值不同时，第一消息中指示的M个RB中的每个RB中用于发送上行数据信号的L个子载波的位置也不同。如图5所示。在S为4时，一个DRB包括来自4个RB中的子载波，即DRB的度为4。当s取不同值时，L个子载波在一个RB中可具有4种可能的分布位置，因此，第一消息中指示的L个子载波可以为第一位置、第二位置、第三位置和第四位置中的一种。
另一种可能的映射方式为，每个RB包括的子载波按照从0到K-1的顺序编号，其中，该RB中用于发送上行数据信号的L个子载波在该RB中的编号具体为s，s+1，s+S，s+1+S，…，s+(L-1)*S，s+1+(L-1)*S，S＝2*K/L，这里，S为步长，S＝2*K/L，S可以大于等于2，s为小于S-1的非负整数，s可以为偶数，s+1+(L-1)*S小于等于K-1。
例如，S的值可以为6。如图6所示，一个RB中包括12个子载波，采用该子载波的映射方式，S＝6时，PUSCH可占用一个RB中的4个子载波即L＝4，这4个子载波在图6中用实线表示。在一个RB中，若将PUSCH占用的子载波分为两组，那么第一组中的第一个子载波与第二组中的第一个子载波之间的间隔为6，即步长S，第一组中的第二个子载波与第二组中的第二个子载波之间的间隔也为6。同理，在采用该子载波的映射方式时，PUSCH占用的一个DRB可由S/2个RB中用于发送上行数据信号的子载波组成，DRB的度为S/2，S为步长。例如，S＝6时，一个DRB由3个RB中用于发送上行数据信号的子载波组成。
需要说明的是，本申请实施例中，M个RB中的每个RB可采用相同的子载波映射方式，也就是说，PUSCH在M个RB中的每个RB中占用的子载波的位置和编号可以是相同的。
步骤S302、终端设备从网络设备接收该第一消息。
步骤S303、终端设备在该N个子载波上向网络设备发送上行数据信号。
在步骤S302和步骤S303中，终端设备可从所述M个RB中确定PUSCH占用的N个子载波，并在该N个子载波上发送上行数据信号。
该M个RB可位于第一频域资源包括的X个RB中，X为大于等于M的正整数，该第一频域资源可以为网络设备配置的上行发送资源，例如可以是带宽部分(bandwidth part，BWP)。相应地，第一消息还可用于指示M个RB在该X个RB中的位置、M的值、L的值、M×L/K值、S的值中的一项或多项信息，以便于终端设备确定该M个RB，根据子载波的映射方式确定该M个RB中包括的用于发送上行数据信号的N个子载波。M×L/K等于N/K，是指M个RB中DRB的个数。
在一种可能的设计中，N个子载波可视为被调度的一个或多个DRB，M个RB中包括该被调度的一个或多个DRB。因此，第一消息指示M个RB在X个RB中的位置可以为：第一消息中包括用于指示DRB的度、DRB的起始位置和DRB的个数的信息。其中，DRB的度可以为预设取值集合中的一个，例如，该预设取值集合可以为{2、4、6}。
DRB的起始位置为被调度的DRB在X个RB中的起始位置。若第一频域资源为网络设备调度的给定BWP，将该BWP中所有可用的度为n的集合称为离散带宽部分(discrete bandwidth part-n，DBWP-n)，那么X个RB可以为该DBWP-n中占用的RB。DRB的起始位置可以是被调度的DRB中编号最小的DRB的编号，也可以是编号最小的DRB中包含的编号最小的RB的编号，从而使终端设备能够确定被调度DRB的起始位置。
DRB的个数为被调度的DRB的个数。在预设取值集合为{2，4，6}时，DBWP-2中的DRB个数为N2，DBWP-4中的DRB个数为N4，DBWP-6中的DRB个数为N6。通常，N2>N4>N6。当被调度的DRB的个数N<＝N6时，终端设备可采用度为6的DRB发送上行数据信号；当被调度的DRB的个数N6<N<＝N4时，终端设备可采用度为4的DRB发送上行数据信号；当被调度的DRB的个数N4<N<＝N2时，终端设备可采用度为2的DRB发送上行数据信号；当被调度的DRB的个数N>N2时，终端设备可采用PRB发送上行数据信号。从而使得终端设备能够根据第一信息中携带的DRB的位置和DRB的个数确定被调度的DRB的频域位置。
步骤S304、网络设备接收终端设备在该N个子载波上发送的上行数据信号。
本申请实施例中，第一频域资源包括连续的Z个RB，Z个RB的编号从0到Z-1，Z为大于等于X的正整数。所述X个RB在第一频域资源中的位置或编号可由网络设备调度，也可以由终端设备通过预设的规则确定。
在一种可能的设计中，终端设备可从网络设备接收第二消息，该第二消息用于指示该X个RB在第一频域资源中的位置或编号，以及X的值。其中，X×L/K为整数，表示X个RB中包括的DRB的个数。例如，终端设备可在接收第一消息之前，从网络设备接收该第二消息，若第一频域资源为网络设备调度的给定的BWP，该BWP中所有可用的度为n的集合称为离散带宽部分(discrete bandwidth part-n，DBWP-n)，那么X个RB可为该DBWP-n占用的RB。该第二消息可具体指示该DBWP-n中起始RB的位置以及该DBWP-n包含的RB的个数。本申请实施例中，网络设备可同时为终端设备配置多个不同度的DBWP。如图6所示，DBWP的度为不同取值时，DBWP的位置和带宽也不同。
在另一种可能的设计中，该X个RB可以为第一频域资源中编号为0到X-1的X个RB；或者，也可以为第一频域资源中编号为Z-X到Z-1的X个RB；或者，还可以为第一频域资源中编号为floor(A/2)到B×z+floor(A/2)-1的X个RB，其中，X＝floor(Z×L/K)×K/L， B＝floor(Z×L/K)，A＝Z-B×L/K。
应理解，本申请实施例中提及的第一消息和第二消息，可以为物理上行控制信道(physical uplink control channel，PUCCH)上承载的上行控制信息(uplink control information，UCI)，或者也可以为网络设备通过物理层控制信令、媒体访问控制(medium access control，MAC)层信令或无线资源控制(radio resource control，RRC)等方式发送的信令或消息，具体并不限定。
由此可知，采用本申请实施例提供的技术方案，用于发送上行数据信号的N个子载波可分布在M个RB中，并且PUSCH可占用一个RB中的部分子载波以发送上行数据信号，从而能够拓宽PUSCH所经历的信道的频域范围，充分获取信道的频域选择性带来的分集增益，提升PUSCH的传输性能。
本申请实施例提供的方法还可以扩展用于下行通信。请参考图8，为本申请实施例提供的另一种通信方法的流程示意图，该方法包括如下的步骤S801至步骤S804：
步骤S801、网络设备向终端设备发送第一消息，该第一消息用于指示终端设备在N个子载波上从网络设备接收下行数据信号；
本申请实施例中，下行数据信号承载在下行数据信道上，该下行数据信号可以是为物理下行共享信道(physical downlink shared channel，PDSCH)，或者可以是其他的下行数据信道。在下文中，将以下行数据信道为PDSCH为例进行介绍。
该N个子载波为PDSCH占用的子载波，即用于发送下行数据信号的子载波。但应注意的是，这N个子载波分布在M个资源块(resource block，RB)中，且只占用M个RB中每个RB中的部分子载波，M为大于等于2的正整数。也就是说，M个RB中的每个RB中用于发送下行数据信号的子载波的数量为L，L小于K，K为一个RB中包括的子载波的个数，例如K可以是12。
可以理解，M个RB中的每个RB包括连续的K个子载波，但只有其中的L个子载波用于发送下行数据信号。鉴于此，本申请实施例中，第一消息还可以用于指示M个RB中的每个RB中用于发送下行数据信号的L个子载波，给出PDSCH到L个子载波的映射方式。
一种可能的映射方式为，每个RB包括的子载波按照从0到K-1的顺序编号，其中，该RB中用于发送下行数据信号的L个子载波在该RB中的编号具体为s，s+S，…，s+(L-1)*S。这里，S为步长，S＝K/L，S可以大于等于2，s为小于S的非负整数，s+(L-1)*S小于等于K-1。
另一种可能的映射方式为，每个RB包括的子载波按照从0到K-1的顺序编号，其中，该RB中用于发送下行数据信号的L个子载波在该RB中的编号具体为s，s+1，s+S，s+1+S，…，s+(L-1)*S，s+1+(L-1)*S，S＝2*K/L，这里，S为步长，S＝2*K/L，S可以大于等于2，s为小于S-1的非负整数，s可以为偶数，s+1+(L-1)*S小于等于K-1。
应理解，本申请实施例中，PDSCH到子载波的映射方式(即PDSCH在一个RB中占用的子载波的位置或编号)可参照图4至图7中示出的PUSCH到子载波的映射方式来实施，区别在于将PUSCH替换为了PDSCH，因此，在此不再赘述。
步骤S802、网络设备向终端设备发送下行数据信号。
本申请实施例中，网络设备可以先发送第一消息后发送下行数据信号，也可以同时发送第一消息和下行数据信息，本申请并不限定。也就是说，上述步骤S802可以在步骤S801 之后执行，也可以与步骤S801同时执行。
步骤S803、终端设备从网络设备接收该第一消息。
步骤S804、终端设备在该N个子载波上从网络设备接收下行数据信号。
在步骤S803和步骤S804中，终端设备可从所述M个RB中确定PDSCH占用的N个子载波，并在该N个子载波上接收下行数据信号。
类似的，M个RB可位于第一频域资源包括的X个RB中，X为大于等于M的正整数，该第一频域资源可以为网络设备配置的下行发送资源，例如可以是带宽部分BWP。相应地，第一消息还可用于指示M个RB在该X个RB中的位置、M的值、L的值、M×L/K值、S的值中的一项或多项信息，以便于终端设备确定该M个RB，根据子载波的映射方式确定该M个RB中包括的用于接收下行数据信号的N个子载波。M×L/K等于N/K，是指M个RB中DRB的个数。
在一种可能的设计中，N个子载波可视为被调度的一个或多个DRB，M个RB中包括该被调度的一个或多个DRB。因此，第一消息指示M个RB在X个RB中的位置可以为：第一消息中包括用于指示DRB的度、DRB的起始位置和DRB的个数的信息。其中，DRB的度、DRB的起始位置和DRB的个数的信息等可参考上一方法实施例，在此不再赘述。
本申请实施例中，终端设备也可从网络设备接收第二消息，该第二消息用于指示该X个RB在第一频域资源中的位置或编号，以及X的值。其中，X×L/K为整数，表示X个RB中包括的DRB的个数。例如，终端设备可在接收第一消息之前，从网络设备接收该第二消息，若第一频域资源为网络设备调度的给定的BWP，该BWP中所有可用的度为n的集合称为离散带宽部分DBWP-n，那么X个RB可为该DBWP-n占用的RB。该第二消息可具体指示该DBWP-n中起始RB的位置以及该DBWP-n包含的RB的个数。本申请实施例中，网络设备可同时配置多个不同度的DBWP。
或者，X个RB也可以通过预设规则来确定，例如X个RB可以为第一频域资源中编号为0到X-1的X个RB，或者也可以为第一频域资源中编号为Z-X到Z-1的X个RB，或者还可以为第一频域资源中编号为floor(A/2)到B×z+floor(A/2)-1的X个RB，其中，X＝floor(Z×L/K)×K/L，B＝floor(Z×L/K)，A＝Z-B×L/K。
应理解，本申请实施例中提及的第一消息和第二消息，可以为物理下行控制信道(physical downlink control channel，PDCCH)上承载的下行控制信息(downlink control information，DCI)，或者也可以为网络设备通过物理层控制信令、媒体访问控制(medium access control，MAC)层信令或无线资源控制(radio resource control，RRC)等方式发送的信令或消息，具体并不限定。

当需要发送数据时，处理器对待发送的数据进行基带处理后，输出基带信号至射频电路，射频电路将基带信号进行射频处理后将射频信号通过天线以电磁波的形式向外发送。当有数据发送到终端设备时，射频电路通过天线接收到射频信号，将射频信号转换为基带信号，并将基带信号输出至处理器，处理器将基带信号转换为数据并对该数据进行处理。为便于说明，图10中仅示出了一个存储器和处理器。在实际的终端设备产品中，可以存在一个或多个处理器和一个或多个存储器。存储器也可以称为存储介质或者存储设备等。存储器可以是独立于处理器设置，也可以是与处理器集成在一起，本申请实施例对此不做限制。
在本申请实施例中，可以将具有收发功能的天线和射频电路视为终端设备的收发单元，将具有处理功能的处理器视为终端设备的处理单元。如图10所示，终端设备包括收发单元1010和处理单元1020。收发单元也可以称为收发器、收发机、收发装置等。处理单元也可以称为处理器，处理单板，处理模块、处理装置等。可选的，可以将收发单元1010中用于实现接收功能的器件视为接收单元，将收发单元1010中用于实现发送功能的器件视为发送单元，即收发单元1010包括接收单元和发送单元。收发单元有时也可以称为收发机、收发器、或收发电路等。接收单元有时也可以称为接收机、接收器、或接收电路等。发送单元有时也可以称为发射机、发射器或者发射电路等。应理解，收发单元1010用于执行上述方法实施例中终端设备侧的发送操作和接收操作，处理单元1020用于执行上述方法实施例中终端设备上除了收发操作之外的其他操作。
