Description

一种通信方法及装置 技术领域
本申请涉及无线通信技术领域，特别涉及一种通信方法及装置。
背景技术
无线通信系统中，资源块(resource block，RB)可以分为物理资源块(physical resource block，PRB)和虚拟资源块(virtual resource block，VRB)，在进行下行(或者上行)数据传输时，下行(或者上行)传输资源是基于VRB进行分配，然后再将其映射到PRB上。进一步地，无线通信系统可以支持基于资源块组(resource block group，RBG)的资源分配。其中，RBG可以包括一个或多个连续的VRB，RBG的大小表示RBG中包含的VRB的个数。
长期演进(Long Term Evolution，LTE)通信系统中，RBG的大小可以是根据小区的带宽(或者载波的带宽)确定的固定大小，例如，小区的带宽小于等于10个RB时，RBG的大小可以为1个VRB，即一个VRB为一个RBG；小区的带宽的大小为11～26个RB时，RBG的大小为2个VRB，即两个VRB为一个RBG。
第五代(the 5th generation，5G)通信系统中，一个载波的最大带宽可以到400MHz，但是终端设备支持的最大带宽能力可能达不到如此大的带宽。因此，在5G通信系统中引入了带宽部分(band width part，BWP)，BWP可以包括一个载波中的一个或多个PRB。网络侧设备可以为BWP配置RBG的大小，通常情况下，网络侧设备为BWP配置的RBG的大小小于或等于BWP的大小，此时，网络侧设备可以以RBG为粒度在BWP上调度终端侧设备的上行数据或下行数据。然而，在一些可能的场景中，网络侧设备为BWP配置的RBG的大小可能会大于BWP的大小，此种情形下，网络侧设备如何在BWP上调度终端侧设备的上行数据或下行数据，仍需进一步的研究。
发明内容
本申请实施方式的目的在于提供一种通信方法及装置，用于在为BWP配置的RBG的大小大于BWP的大小的场景下，实现网络侧设备和终端侧设备在BWP上进行数据传输。
第一方面，本申请实施例提供一种通信方法，该方法包括：
通信装置若确定BWP的大小小于为所述BWP配置的RBG的大小，则确定所述BWP对应第一RBG，所述第一RBG的大小等于所述BWP的大小；进而，通信装置在所述第一RBG中的虚拟资源块VRB映射的物理资源块PRB上进行数据传输。
在一种可能的设计中，上述通信装置可以为网络侧设备，此种情形下，该方法还可以包括：通信装置向终端侧设备发送第一配置信息，第一配置信息包括BWP的大小；以及，通信装置向终端侧设备发送第二配置信息，第二配置信息包括为BWP配置的RBG的大小。
在一种可能的设计中，上述通信装置可以为终端侧设备，此种情形下，该方法还可以包括：通信装置接收网络侧设备发送的第一配置信息，第一配置信息包括BWP的大小；以及，通信装置接收网络侧设备发送的发送第二配置信息，第二配置信息包括为BWP配置的RBG的大小。
采用上述方法，当确定BWP的大小小于配置的RBG的大小，本申请实施例中网络侧设备和终端侧设备均可确定BWP对应第一RBG，从而保证网络侧设备和终端侧设备所理解的BWP对应的RBG的大小一致，且由于第一RBG的大小等于BWP的大小，从而能够有效避免网络侧设备所调度的RBG中的VRB所映射的PRB包括不属于BWP的PRB，保证数据传输的准确性。
在一种可能的设计中，所述通信装置若确定BWP的大小小于为所述BWP配置的RBG的大小，则确定所述BWP对应第一RBG，包括：所述通信装置若确定BWP的大小小于为所述BWP配置的RBG的大小，且根据所述BWP的起始资源块索引、所述BWP的大小和配置的RBG的大小得到所述BWP对应的RBG的个数为1，则确定所述BWP对应第一RBG。
考虑到BWP对应的RBG的个数大于或等于2时，可以计算得到BWP对应的第一个RBG的大小以及计算得到BWP对应的最后一个RBG，进而得到BWP对应的RBG包括BWP对应的第一个RBG和BWP对应的最后一个RBG，此时不会出现网络侧设备和终端侧设备所理解的BWP对应的RBG的大小不一致。因此，本申请实施例中可以在BWP对应的RBG的个数为1的情况下，确定所述BWP对应第一RBG，以避免出现网络侧设备和终端侧设备所理解的BWP对应的RBG的大小不一致。
第二方面，本申请实施例提供一种通信方法，该方法包括：
通信装置若确定BWP的大小小于为所述BWP配置的RBG的大小，且根据所述BWP的起始资源块索引、所述BWP的大小和配置的RBG的大小得到所述BWP对应的RBG的个数为1，则确定所述BWP对应第二RBG或第三RBG；进而，通信装置在所述第二RBG或第三RBG中的部分或全部VRB映射的PRB上进行数据传输；其中，所述第二RBG的大小是根据所述BWP的起始资源块索引和所述配置的RBG的大小得到的；所述第三RBG的大小是根据所述BWP的起始资源块索引、所述BWP的大小和所述配置的RBG的大小得到的。
在一种可能的设计中，上述通信装置可以为网络侧设备，此种情形下，该方法还可以包括：通信装置向终端侧设备发送第一配置信息，第一配置信息包括BWP的大小；以及，通信装置向终端侧设备发送第二配置信息，第二配置信息包括为BWP配置的RBG的大小。
在一种可能的设计中，上述通信装置可以为终端侧设备，此种情形下，该方法还可以包括：通信装置接收网络侧设备发送的第一配置信息，第一配置信息包括BWP的大小；以及，通信装置接收网络侧设备发送的发送第二配置信息，第二配置信息包括为BWP配置的RBG的大小。
采用上述方法，当确定BWP的大小小于配置的RBG的大小，本申请实施例中网络侧设备和终端侧设备均可确定BWP对应第二RBG(或第三RBG)，从而保证网络侧设备和终端侧设备所理解的BWP对应的RBG的大小一致；且以BWP对应第二RBG为例，当第二RBG大于BWP的大小时，网络侧设备和终端侧设备可以在第二RBG中的部分VRB映射的PRB上进行数据传输(丢弃第二RBG中的VRB映射的PRB中不属于BWP的PRB)，当第二RBG等于BWP的大小时，网络侧设备和终端侧设备可以在第二RBG中的全部VRB映射的PRB上进行数据传输。
在一种可能的设计中，所述通信装置若确定BWP的大小小于为所述BWP配置的RBG的大小，且根据所述BWP的起始资源块索引、所述BWP的大小和配置的RBG的大小得 到所述BWP对应的RBG的个数为1，则确定所述BWP对应第三RBG，包括：所述通信装置若确定BWP的大小小于为所述BWP配置的RBG的大小，且第三RBG的大小大于0，以及根据所述BWP的起始资源块索引、所述BWP的大小和配置的RBG的大小得到所述BWP对应的RBG的个数为1，则确定所述BWP对应第三RBG。
在一种可能的设计中，所述通信装置在所述第二RBG中的部分或全部VRB映射的PRB上进行数据传输，包括：所述通信装置在所述第二RBG中的前N个VRB映射的PRB上进行数据传输；其中，N为所述BWP包括的PRB的个数。
在一种可能的设计中，所述通信装置在所述第三RBG中的部分或全部VRB映射的PRB上进行数据传输，包括：所述通信装置在所述第三RBG中的后N个VRB映射的PRB上进行数据传输；其中，N为所述BWP包括的PRB的个数。
第三方面，本申请实施例提供一种通信方法，该方法包括：
网络侧设备为终端侧设备配置BWP的大小；以及，网络侧设备为所述BWP配置RBG的大小，若确定所述BWP的大小大于或等于配置的RBG的大小，则向所述终端侧设备发送第三配置信息，所述第三配置信息包括为所述BWP配置的RBG的大小。
采用上述方法，网络侧设备在确定BWP的大小大于或等于配置的RBG的大小的情况下，方可向终端侧设备发送配置的RBG的大小，从而保证终端侧设备接收到的BWP的大小大于或等于配置的RBG的大小。
在一种可能的设计中，所述方法还包括：网络侧设备若确定所述BWP的大小小于所述配置的RBG的大小，则将所述BWP的大小调大，和/或，将所述配置的RBG的大小调小；调整后的BWP的大小大于或等于调整后的RBG的大小；并向终端侧设备发送第四配置信息，第四配置信息包括所述调整后的BWP的大小和/或所述调整后的RBG的大小。

下面对本申请实施例涉及的相关技术特征进行解释。需要说明的是，这些解释是为了让本申请实施例更容易被理解，而不应该视为对本申请所要求的保护范围的限定。
(1)BWP
5G通信系统中，将用于通信的频率按照其范围分为频率范围1(frequency range 1，FR1)和频率范围2(frequency range 2，FR2)。FR1对应的频率范围为450MHz至6000MHz，对应低频频段。FR2对应的频率范围为24250MHz至52600MHz，对应高频频段。位于不同FR时，信道带宽可以不同，比如FR1的带宽可以是5MHz，10MHz，15MHz，20MHz，25MHz，30MHz，40MHz，50MHz，60MHz，80MHz和100MHz，FR2的带宽可以是50MHz，100MHz，200MHz和400MHz等。
为适配终端侧设备的带宽能力，可以在一个载波支持的带宽(可称为载波带宽，具体取值可以为10MHz、15MHz、20MHz、50MHz、100MHz或400MHz等)内为终端侧设备配置BWP，一个载波中可配置多个BWP，例如一个载波可以配置4个BWP。BWP有时也可称为子带(subband)带宽、窄带(narrowband)带宽，或者其他的名称，本申请对名称并不做限定，为了便于描述，以名称是BWP为例说明。例如，一个BWP包含K(K>0)个子载波；或者，一个BWP为N个不重叠的RB所在的频域资源，该RB的子载波间隔可以为15KHz、30KHz、60KHz、120KHz、240KHz、480KHz或其他值；或者，一个BWP为M个不重叠的RBG所在的频域资源，例如，一个RBG包括P(P>0)个连续的RB，该RB的子载波间隔(subcarrier spacing，SCS)可以为15KHz、30KHz、60KHz、120KHz、240KHz、480KHz或其他值，例如为2的整数倍。
示例性地，一个BWP可以表示为在指定的载波内的BWP i，其中i表示BWP的编号；BWP i的大小可以是指BWP中包含的PRB的个数，可以表示为
Figure PCTCN2019101217-appb-000001
BWP i的起始资源块索引是指BWP i相对于CRB0的偏移量，可以表示为
Figure PCTCN2019101217-appb-000002
比如，BWP i相对于CRB0的偏移量为25，则BWP i的起始资源块索引为25。如图1b所述，为配置的3种不同的BWP 示例，其中，BWP1带宽40MHz，子载波间隔15kHz；BWP2带宽10MHz，子载波间隔15kHz；BWP3带宽20MHz，子载波间隔60kHz。
(2)VRB、PRB和公共资源块(common resource block，CRB)
NR通信系统中，定义了VRB、PRB和CRB三种资源块概念。其中，VRB可以定义在一个BWP(比如BWP i)内，VRB编号从0到
Figure PCTCN2019101217-appb-000003
频域资源分配通常先是分配VRB，再通过非交织或交织的方式从VRB向PRB映射。PRB可以定义在一个BWP(比如BWP i)内，PRB编号从0到
Figure PCTCN2019101217-appb-000004
CRB编号从0开始，CRB 0的子载波0的中心与Point A一致；其中，Point A可以理解为针对于一个小区的资源块网格的公共参考点。示例性地，在终端侧设备的初始接入阶段，网络侧设备可以将Point A包含在小区的系统消息中发送给正在接入该小区的终端侧设备，相应地，终端侧设备可以根据系统消息确定该小区的Point A，后续，网络侧设备可以基于Point A来为终端侧设备分配资源(比如BWP)。
示例性地，如图1c所示，在BWP i内，BWP i的子载波间隔参数为μ，BWP i内的PRB的编号(表示为
Figure PCTCN2019101217-appb-000005
)与CRB的编号(表示为
Figure PCTCN2019101217-appb-000006
)的关系可以为：
Figure PCTCN2019101217-appb-000007
其中，
Figure PCTCN2019101217-appb-000008
表示以CRB 0作为参考的BWP i的起始资源块索引。
(3)名义上RBG的大小(nominal RBG size)
示例性地，网络侧设备为终端侧设备配置一个或多个BWP后，可以再进一步为一个或多个BWP分别配置RBG的大小，网络侧设备为某一BWP(比如BWP1)配置的RBG的大小，可以理解为名义上RBG的大小，因为即使网络侧设备为BWP1配置了RBG的大小等于P，但是实际确定出的BWP1对应的RBG的大小所包括的PRB个数可能小于P。
本申请实施例中，为BWP配置的RBG的大小可以简称为配置的RBG的大小。
在一个示例中，网络侧设备可以向终端侧设备发送高层信令，高层信令中可以包括BWP1的配置参数rbg-Size，用于为BWP1配置的RBG的大小。
如下所示，为高层信令的部分结构示例：
PDSCH-Config::＝                       SEQUENCE{
…
rbg-Size                                ENUMERATED{config1,config2},
由此可以看出，rbg-Size有两种配置，分别为config1和config2，如表1所示，为不同配置下，为BWP配置的RBG的大小。
表1：为BWP配置的RBG的大小
BWP的大小 Configuration 1 Configuration 2
1–36 2 4
37–72 4 8
73–144 8 16
145–275 16 16
示例性地，当配置rbg-Size等于config1时，表示可以选取表1中的“Configuration 1”一列，当配置rbg-Size等于config2时，表示可以选取表1中的“Configuration 2”一列；进而终端侧设备可以根据BWP1的大小确定对应的为表1中的哪一行，从而结合行和列确定出为BWP1配置的RBG的大小。
举个例子，针对于BWP1配置的PDSCH-Config->rgb-Size等于config2，BWP1的大 小是20个PRB，则根据表1可知，BWP1大小为20个PRB时对应第一行，rgb-Size等于config2对应第二列，从而终端侧设备可以确定为BWP1配置的RBG的大小等于4。
(4)BWP对应的RBG的个数和各个RBG的大小
示例性地，终端侧设备确定出为BWP配置的RBG的大小后，可以进一步确定出BWP对应的RBG的个数和各个RBG的大小。
比如，终端侧设备可以采用如下公式确定BWP i对应的RBG的个数：
Figure PCTCN2019101217-appb-000009
其中，N RBG表示BWP i对应的RBG的个数，P表示为BWP i配置的RBG的大小，
Figure PCTCN2019101217-appb-000010
表示BWP i的大小，
Figure PCTCN2019101217-appb-000011
表示BWP i的起始资源块索引。
举个例子，参见图1d所示，BWP1的大小
Figure PCTCN2019101217-appb-000012
等于20个PRB，为BWP1配置的RBG的大小P等于4，BWP1的起始资源块索引
Figure PCTCN2019101217-appb-000013
为5，进而根据公式1可得到BWP1对应的RBG的个数为6。
此种情形下，若确定出BWP1对应的RBG的个数为6，则网络侧设备向终端侧设备发送DCI(假设采用的资源分配方式为type0)时，DCI中的频域资源分配指示(frequency domain resource assignment)域的比特长度可以为6，6个比特中的每一个比特用于指示对应的RBG是否用于数据传输，比如当其中一个比特的比特状态为“1”，则表示该比特对应的RBG用于数据传输(即该比特对应的RBG分配给了终端侧设备)，比特状态为“0”，则表示该比特对应的RBG不用于数据传输(即该比特对应的RBG没有分配给终端侧设备)。例如，对于BWP1，频域资源分配指示域的第一个比特对应第一个RBG，第二个比特对应第二个RBG，以此类推；终端侧设备接收到DCI后，若确定频域资源分配指示域为111000，则表示BWP1中的前3个RBG分配给终端侧设备用于数据传输，而后3个RBG未分配给终端侧设备；进而，终端侧设备可以在前3个RBG中的VRB所映射的PRB上进行数据传输。
考虑到不同BWP的起始位置和终止位置可能不同，参见图1d所示，BWP1的起始位置对应索引为5的CRB，终止位置对应索引为24的CRB，而BWP2的起始位置对应索引为10的CRB，终止位置对应索引为24的CRB；因此，为了使同一小区内的不同BWP在相同的nominal RBG size配置下得到的RBG尽量对齐，可以采用如下公式2来确定BWP i对应的第一个RBG，以及采用如下公式3来确定BWP i对应的最后一个RBG，且BWP i对应的除第一个RBG和最后一个RBG以外的其它RBG的大小等于P。

参见图1d所示的BWP1和BWP2，对于BWP1来说：

P＝4，
Figure PCTCN2019101217-appb-000020
对于BWP1来说：
Figure PCTCN2019101217-appb-000021
P＝4，
Figure PCTCN2019101217-appb-000022
(5)预编码资源块组(precoding resource block group，PRG)
NR通信系统中，引入了PRG，PRG可以理解为预编码粒度(precoding granularity)，， 假设PRG为一个频域上连续的P′ BWP,i个RB，P′ BWP,i可以是2、4或者调度带宽(wideband)中的一个值。终端侧设备在一个PRG内的连续分配的PRB使用相同的预编码矩阵，可以理解为一个PRG内的连续分配的PRB使用相同的线性变换。
其中，P′ BWP,i的取值解释如下：
①P′ BWP.i＝wideband，表示终端侧设备不期待被调度非连续的PRB，即网络侧设备给终端侧设备调度的PRB都是连续的，且终端侧设备假设这些调度的PRB都是用相同的预编码处理。
②P′ BWP.i＝2 or 4，表示一个PRG内包含连续P′ BWP,i个PRB，若干个PRG划分BWPi为多段。1个PRG内的连续PRB个数可能是1或多于1。
确定BWPi对应的PRG的方法与确定BWPi对应的RBG的方法类似。比如，BWPi对应的第一个PRG的大小等于
Figure PCTCN2019101217-appb-000023
如果
Figure PCTCN2019101217-appb-000024
则BWPi对应的最后一个PRG的大小等于
Figure PCTCN2019101217-appb-000025
如果
Figure PCTCN2019101217-appb-000026
则BWPi对应的最后一个PRG的大小等于P′ BWP,i。
网络侧设备可以通过高层信令配置P′ BWP,i，比如对于由小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)加扰的DCI format 1_1调度的PDSCH，当PDSCH-Config中没有配置prb-BundlingType时，P′ BWP,i默认为2；当prb-BundlingType设置为'dynamicBundling'时，bundleSizeSet1和bundleSizeSet2中配置2个取值集合，第一个集合可以在集合{2,4,wideband}中取1个或2个值，第二个集合只能在{2,4,wideband}集合中取1个值。
进一步地，如果PDSCH-Config中没有配置prb-BundlingType时或配置为'staticBundling'时，DCI format 1_1中的PRB bundling size indicator域的比特长度为0比特，即不能动态指示PRG。
如果PDSCH-Config中配置prb-BundlingType为'dynamicBundling'，则当取值为0时，终端侧设备可以使用第二个集合中的P′ BWP,i；取值为1且第一个集合中配置了一个值，终端侧设备可以使用这个值；取值为1且第一个集合中配置了两个值，'n2-wideband'(这个值对应2和wideband)或'n4-wideband'(这个值对应4和wideband)，终端侧设备可以使用这个值。也就是说，配置两个值时，网络侧设备会在这个集合内配置一个包含两个含义的一个信令，即会配置'n4-wideband'，而不会配置2个值'n4'和'wideband'。
本申请实施例中，如果调度的PRB是连续的且调度的PRB大于
Figure PCTCN2019101217-appb-000027
则P′ BWP,i等于调度带宽，否则P′ BWP,i分别等于配置的2或4。例如，BWP1的起始资源块索引
Figure PCTCN2019101217-appb-000028
大小为
Figure PCTCN2019101217-appb-000029
如果网络侧设备采用type 0来调度，则可以配置prb-BundlingType为'dynamicBundling＝n4-wideband'，DCI中的PRB bundling size indicator域等于'1'，当用于数据传输的PRB(或者说调度的PRB)个数不同时，对应的PRG如图1e和图1f所示。其中，图1e表示，调度的PRB个数大于
Figure PCTCN2019101217-appb-000030
此时
Figure PCTCN2019101217-appb-000031
等于调度带宽，即调度的PRB都是用相同的预编码处理。图1f表示，调度的PRB个数小于
Figure PCTCN2019101217-appb-000032
此时P′ BWP,i等于4，即BWP1中前3个PRB使用相同的预编码处理，第四个至第七个PRB使用相同的预编码处理。
基于上述介绍，下面对本申请实施例进行描述。
根据上述内容可知，当网络侧设备为终端侧设备配置的BWP的大小大于或等于为BWP配置的RBG的大小时，网络侧设备和终端侧设备可以依据上述公式1、公式2和公式3确定出BWP对应的RBG的个数以及各个RBG的大小，进而网络侧设备可以以RBG为粒度在BWP上调度终端侧设备的上行数据或下行数据。
然而，在一些可能的场景中，网络侧设备为终端侧设备配置的BWP的大小可能小于为BWP配置的RBG的大小。比如场景1，终端侧设备的能力支持BWP的大小小于为BWP配置的RBG的大小，此种情形下，网络侧设备为终端侧设备配置的BWP的大小可能小于为BWP配置的RBG的大小；又比如场景2，在没有配置同步信号块(synchronous signal block，SSB)的载波上，且不存在BWP的大小大于或等于SSB带宽的限制，因此，网络侧设备为终端侧设备配置的BWP的大小可能小于为BWP配置的RBG的大小。
本申请实施例将主要研究当BWP的大小小于为BWP配置的RBG的大小时，网络侧设备和终端侧设备如何在BWP上进行数据传输。
示例性地，当BWP的大小小于为BWP配置的RBG的大小时，本申请实施例提供一种可能的思路为，网络侧设备和终端侧设备依据上述公式1、公式2和公式3来确定BWP对应的RBG的个数以及RBG的大小，进而网络侧设备可以基于BWP对应的RBG在BWP上调度终端侧设备的上行数据和下行数据。但，由于网络侧设备为终端侧设备配置的BWP的大小小于为BWP配置的RBG的大小，因此，可能出现网络侧设备和终端侧设备对BWP对应的RBG的大小理解不一致的问题。
举个例子，
Figure PCTCN2019101217-appb-000033
P＝4，即BWP i的大小只有1个PRB，但是P＝4，此种情况下，根据公式1计算得到BWP i对应的RBG的个数为1，该RBG可以理解为BWP i对应第一个RBG，也可以理解为BWP i对应最后一个RBG。若将该RBG可以理解为BWP i对应第一个RBG，则根据上述公式2可得RBG的大小为4，若将该RBG可以理解为BWP i对应最后一个RBG，则根据上述公式3可得RBG的大小为1。如此，若网络侧设备将BWP i对应的RBG理解为BWP i对应的第一个RBG，而终端侧设备将BWP i对的应RBG理解为BWP i对应的最后一个RBG，则会出现网络侧设备和终端侧设备对BWP i对应的RBG的大小理解不一致的问题。
考虑到目前网络侧设备为BWP i配置的RBG的大小可以为2或4，在此基础上，BWP i的大小小于为BWP i配置的RBG的大小的情形可以包括：
情形1，P＝2，

的取值为4n+2、4n+3，根据公式1可计算得到BWP i对应2个RBG，进而可分别根据公式2和公式3得到第一个RBG的大小和最后一个RBG的大小，此时也不会出现理解不一致的问题。
基于上述对情形1至情形4的分析，本申请实施例提供三种可能的方案，分别为方案一、方案二和方案三。
需要说明的是，方案一、方案二中所涉及的通信装置可以为第一通信装置或第二通信装置。其中，第一通信装置可以是网络侧设备或能够支持网络侧设备实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片或芯片系统。第二通信装置可以是终端侧设备或能够支持终端侧设备实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片或芯片系统。
方案一
图2为本申请实施例方案一提供的一种通信方法所对应的流程示意图，如图2所示，包括：
步骤201，通信装置若确定BWP的大小小于为BWP配置的RBG的大小，则可以确定BWP对应第一RBG，或者说，确定BWP对应的RBG为第一RBG，第一RBG的大小等于BWP的大小。
步骤202，通信装置在第一RBG中的VRB映射的PRB上进行数据传输。
本申请实施例中，由于确定BWP对应第一RBG，因此从网络侧设备的角度来看，网络侧设备所发送的DCI中的频域资源分配指示域中可以包括1个比特，该比特的比特状态可以为1，指示第一RBG用于数据传输。
由于第一RBG的大小等于BWP的大小，因此通信装置在第一RBG中的VRB映射的PRB上进行数据传输，可以理解为，通信装置在第一RBG中的全部VRB映射的PRB上进行数据传输。
本申请实施例中，通信装置确定BWP对应第一RBG的实现方式可以有多种，下面描述几种可能的实现方式。
实现方式1
通信装置若确定BWP的大小小于为这个BWP配置的RBG的大小，则可以直接确定BWP对应第一RBG。在该种实现方式中，通信装置确定BWP的大小小于配置的RBG的大小后，可以无需根据上述公式1、公式2和公式3来进行相关计算，而是直接确定BWP对应第一RBG，能够降低处理复杂度，提高处理效率。
实现方式2
通信装置若确定BWP的大小小于为这个BWP配置的RBG的大小，且根据上述公式3计算得到BWP对应的最后一个RBG(即为
Figure PCTCN2019101217-appb-000080
)的大小大于0，则可以直接确定BWP对应第一RBG。通信装置若确定BWP的大小小于配置的RBG的大小，且根据上述公式3计算得到BWP对应的最后一个RBG(即为
Figure PCTCN2019101217-appb-000081
)的大小等于0，则可以根据上述公式2计算得到BWP对应的第一个RBG的大小(即为
Figure PCTCN2019101217-appb-000082
)，并确定BWP对应的RBG为BWP对应的第一个RBG(此时，BWP对应的第一个RBG的大小等于BWP的大小，也就是说，BWP对应的第一个RBG即是第一RBG)。
在该种实现方式中，通信装置确定BWP的大小小于为这个BWP配置的RBG的大小后，可以先根据上述公式3计算得到BWP对应的最后一个RBG的大小，若BWP对应的最后一个RBG的大小大于0，则可以根据公式2得到BWP对应的第一个RBG的大小，并确定BWP对应的RBG为BWP对应的第一个RBG，无需根据公式1计算BWP对应的RBG的个数；若BWP对应的最后一个RBG的大小等于0，则可以直接确定BWP对应第一RBG，而无需再根据公式2计算BWP对应的第一个RBG的大小，也无需根据公式1计算BWP对应的RBG的个数。
采用上述实现方式，通信装置将BWP对应的最后一个RBG的大小作为参考，由于当BWP对应的最后一个RBG的大小等于0时，可能不会出现网络侧设备和终端侧设备所理解BWP对应的RBG的大小不一致的问题，此时可以继续沿用前文所描述的方式来确定BWP对应的RBG；而当BWP对应的最后一个RBG的大小大于0时，可能会出现网络侧设备和终端侧设备所理解BWP对应的RBG的大小不一致的问题，此时可以确定BWP对应第一RBG，从而保证网络侧设备和终端侧设备所理解BWP对应的RBG的大小一致，且由于无需根据公式1计算BWP对应的RBG的个数，从而能够降低处理复杂度。
实现方式3
通信装置若确定BWP的大小小于为这个BWP配置的RBG的大小，且根据上述公式1计算得到BWP对应1个RBG，则可以直接确定BWP对应第一RBG。通信装置若确定BWP的大小小于配置的RBG的大小，且根据上述公式1计算得到BWP对应的RBG的个数大于或等于2，则可以根据上述公式2计算得到BWP对应的第一个RBG的大小以及根据上述公式3计算得到BWP对应的最后一个RBG，进而得到BWP对应的RBG包括BWP对应的第一个RBG和BWP对应的最后一个RBG。
在该种实现方式中，通信装置确定BWP的大小小于配置的RBG的大小后，可以先根据公式1计算得到BWP是否对应1个RBG，若是，则无需根据上述公式2和公式3来进行相关计算，而是直接确定BWP对应第一RBG。
采用上述实现方式，通信装置将BWP对应的RBG的个数作为参考，由于当BWP对应的RBG的个数大于或等于2时，可能不会出现网络侧设备和终端侧设备所理解BWP对应的RBG的大小不一致的问题，此时可以继续沿用前文所描述的方式来确定BWP对应的RBG；而当BWP对应的RBG的个数等于1时，可能会出现网络侧设备和终端侧设备所理 解BWP对应的RBG的大小不一致的问题，此时可以确定BWP对应第一RBG，从而保证网络侧设备和终端侧设备所理解BWP对应的RBG的大小一致，且由于无需根据公式2和公式3计算BWP对应的RBG的个数，从而能够降低处理复杂度。
实现方式4
通信装置若确定BWP的大小小于为这个BWP配置的RBG的大小，且根据上述公式1计算得到BWP对应1个RBG，以及根据上述公式3计算得到BWP对应的最后一个RBG的大小大于0，则确定BWP对应第一RBG。通信装置若确定BWP的大小小于配置的RBG的大小，且根据上述公式3计算得到BWP对应的最后一个RBG的大小等于0(根据上述表2至表5可以看出，BWP对应的最后一个RBG的大小等于0时，BWP只对应1个RBG)，则可以上述公式2计算得到BWP对应的第一个RBG的大小，并确定BWP对应的RBG为BWP对应的第一个RBG(此时，BWP对应的第一个RBG的大小等于BWP的大小，也就是说，BWP对应的第一个RBG即是第一RBG)。
采用上述实现方式，通信装置将BWP对应的RBG的个数和BWP对应的最后一个RBG的大小作为参考，从而能够给更加准确地确定当前场景是否为会出现网络侧设备和终端侧设备所理解BWP对应的RBG的大小不一致的问题的场景，若是，则可以确定BWP对应第一RBG，以保证网络侧设备和终端侧设备所理解BWP对应的RBG的大小一致。
方案二
图3为本申请实施例方案二提供的一种通信方法所对应的流程示意图，如图3所示，包括：
步骤301，通信装置若确定BWP的大小小于为这个BWP配置的RBG的大小，则可以确定BWP对应第二RBG或第三RBG，或者说，确定BWP对应的RBG为第二RBG或第三RBG。
其中，第二RBG的大小可以是根据BWP的起始资源块索引和配置的RBG的大小得到的，比如可以根据上述公式2计算得到，此时第二RBG可以理解为BWP对应的第一个RBG。第三RBG的大小是根据BWP的起始资源块索引、BWP的大小和配置的RBG的大小得到的，比如可以根据上述公式3计算得到，此时第三RBG可以理解为BWP对应的最后一个RBG。
在一种可能的实现方式中，通信装置确定BWP对应第二RBG，可以包括：通信装置若确定BWP的大小小于配置的RBG的大小，且根据上述公式1计算得到BWP对应1个RBG，则可以确定BWP对应第二RBG。
通信装置确定BWP对应第三RBG，可以包括：通信装置若确定BWP的大小小于配置的RBG的大小，且根据上述公式1计算得到BWP对应1个RBG，以及根据上述公式3计算得到BWP对应的最后一个RBG的大小大于0，则可以确定BWP对应第三RBG。
步骤302，通信装置在第二RBG或第三RBG中的VRB映射的PRB上进行数据传输。
本申请实施例中，由于确定BWP对应第二RBG(或第三RBG)，因此从网络侧设备的角度来看，网络侧设备所发送的DCI中的频域资源分配指示域中可以包括1个比特，该比特的比特状态可以为1，指示第二RBG(或第三RBG)用于数据传输。
由于第二RBG的大小可能大于或等于BWP的大小，因此，通信装置在第二RBG中的VRB映射的PRB上进行数据传输可以理解为，通信装置在第二RBG中的部分或全部VRB映射的PRB上进行数据传输。示例性地，通信装置可以在第二RBG中的前N个VRB 映射的PRB上进行数据传输，其中，N为BWP包括的PRB的个数。
由于第三RBG的大小可能大于或等于BWP的大小，因此，通信装置在第三RBG中的VRB映射的PRB上进行数据传输可以理解为，通信装置在第三RBG中的部分或全部VRB映射的PRB上进行数据传输。示例性地，通信装置可以在第三RBG中的后N个VRB映射的PRB上进行数据传输。
需要说明的是，若步骤301中通信装置确定BWP对应第二RBG，则在步骤302中通信装置可以在第二RBG中的VRB映射的PRB上进行数据传输；若步骤301中通信装置确定BWP对应第三RBG，则在步骤302中通信装置可以在第三RBG中的VRB映射的PRB上进行数据传输。
以通信装置确定BWP对应第二RBG，并在第二RBG中的VRB映射的PRB上进行数据传输为例，描述几种可能的示例。

通信装置可以根据公式2计算得到第二RBG的大小(即为3)，进而在第二RBG中的第一个VRB所映射的PRB上进行数据传输，丢弃第二RBG中的后两个VRB所映射的PRB或者说不在第二RBG中的后两个VRB所映射的PRB上进行数据传输。

通信装置可以根据公式2计算得到第二RBG的大小(即为2)，进而在第二RBG中的第一个VRB所映射的PRB上进行数据传输，丢弃第二RBG中的第二个VRB所映射的PRB或者说不在第二RBG中的第二个VRB所映射的PRB上进行数据传输。
示例3：BWP的大小为

为BWP配置的RBG大小配置为P＝4
当BWP的起始资源块索引为

时，通信装置可以根据公式2计算得到第二RBG的大小(即为4)，进而在第二RBG中的第一个VRB和第二个VRB所映射的PRB上进行数据传输，丢弃第二RBG中的后两个VRB所映射的PRB或者说不在第二RBG中的后两个VRB所映射的PRB上进行数据传输。
当BWP的起始资源块索引为

时，通信装置可以根据公式2计算得到第二RBG的大小(即为3)，进而在第二RBG中的第一个VRB和第二个VRB所映射的PRB上进行数据传输，丢弃第二RBG中的最后一个VRB所映射的PRB或者说不在第二RBG中的最后一个VRB所映射的PRB上进行数据传输。

时，通信装置可以根据公式2计算得到第二 RBG的大小(即为4)，进而在第二RBG中的前三个VRB所映射的PRB上进行数据传输，丢弃第二RBG中的最后一个VRB所映射的PRB或者说不在第二RBG中的最后一个VRB所映射的PRB上进行数据传输。
针对于上述方案一(或方案二)，下面从网络侧设备和终端侧设备交互的角度，描述一种可能的实现流程。
图4为本申请实施例提供的一种通信方法的交互流程示意图，如图4所示，包括：
步骤401，网络侧设备向终端侧设备发送第一配置信息，第一配置信息可以包括网络侧设备为终端侧设备配置的BWP的大小。示例性地，第一配置信息还可以包括所述BWP的资源块起始索引。
相应地，在步骤402中，终端侧设备接收来自网络侧设备的第一配置信息。
此处，网络侧设备向终端侧设备发送第一配置信息的方式可以有多种，比如通过广播消息或RRC信令来发送，具体不做限定。
需要说明的是，BWP的大小和所述BWP的资源块起始索引可以由一条信令来发送，或者，也可以通过多条信令来发送，具体不做限定。
步骤403，网络侧设备向终端侧设备发送第二配置信息，第二配置信息包括为BWP配置的RBG的大小，此处配置的RBG的大小即为名义上RBG的大小。
相应地，在步骤404中，终端侧设备接收来自网络侧设备的第二配置信息。
此处，网络侧设备向终端侧设备发送第二配置信息的方式可以有多种，比如通过广播消息或RRC信令来发送，具体不做限定。
需要说明的是，上述第一配置信息和第二配置信息可以通过同一条信令来发送，或者，也可以通过不同的信令来发送，具体不做限定。
步骤405，终端侧设备若确定BWP的大小小于配置的RBG的大小，则确定BWP对应第一RBG。
步骤406，网络侧设备若确定BWP的大小小于配置的RBG的大小，则确定BWP对应第一RBG。
步骤407，网络侧设备和终端侧设备在第一RBG中的VRB映射的PRB上进行数据传输。
采用上述方法，当确定BWP的大小小于配置的RBG的大小，本申请实施例中网络侧设备和终端侧设备均可确定BWP对应第一RBG，从而保证网络侧设备和终端侧设备所理解BWP对应的RBG的大小一致，且由于第一RBG的大小等于BWP的大小，从而能够有效避免网络侧设备所调度的RBG中的VRB所映射的PRB包括不属于BWP的PRB。
需要说明的是：(1)上述步骤401至步骤407为方案一对应的交互流程，方案二对应的交互流程可以参照方案一的交互流程，其与方案一的交互流程差异之处在于：在方案一对应的交互流程中，步骤405的终端侧设备和步骤406中的网络侧设备确定BWP对应第一RBG，进而步骤407中网络侧设备和终端侧设备在第一RBG中的VRB映射的PRB上进行数据传输；而在方案二对应的交互流程中，步骤405的终端侧设备和步骤406中的网络侧设备确定BWP对应第二RBG(或第三RBG)，进而步骤407中网络侧设备和终端侧设备在第二RBG(或第三RBG)中的VRB映射的PRB上进行数据传输。
(2)上述图4中所涉及的步骤编号仅为执行流程的一种可能的示例，并不构成对各 个步骤的执行先后顺序的限制。本申请实施例中，相互之间没有时序依赖关系的步骤之间没有严格的执行顺序。
(3)上述步骤401至步骤407仅是对交互流程进行描述，其中有些步骤(比如步骤405至步骤407)的具体实现可以参照上述方案一中的描述。
方案三
在方案三中，将主要研究在终端侧设备不期待被配置BWP的大小小于为BWP配置的RBG的大小的情形下，网络侧设备的一些可能的实现方式。
图5为本申请实施例方案三提供的一种通信方法所对应的流程示意图，如图5所示，包括：
步骤501，网络侧设备为终端侧设备配置BWP的大小。
步骤502，网络侧设备为BWP配置RBG的大小。
在该步骤中，网络侧设备可以基于现有方式为BWP配置RBG的大小。
步骤503，网络侧设备判断BWP的大小是否大于或等于配置的RBG的大小，若是，则执行步骤504，若否，则执行步骤505。
示例性地，网络侧设备判断BWP的大小是否大于或等于配置的RBG的大小的具体实现方式可以有多种，比如网络可以预先存储情形1至情形4，当确定BWP的大小和配置的RBG的大小属于上述情形1至情形4中的任一种情形时，则可以确定BWP的大小小于配置的RBG的大小，否则可以确定BWP的大小大于或等于配置的RBG的大小。
步骤504，网络侧设备向终端侧设备发送第三配置信息，所述第三配置信息包括BWP的大小和配置的RBG的大小。
步骤505，网络侧设备将BWP的大小调大，和/或，将配置的RBG的大小调小；调整后的BWP的大小大于或等于调整后的RBG的大小。
示例性地，网络侧设备将BWP的大小调大和/或将配置的RBG的大小调小的实现方式可以有多种。
在一种可能的实现方式中，网络侧设备可以根据配置的RBG的大小，按照预设调整值(比如1)将BWP的大小调大。比如，配置的RBG的大小为4，BWP的大小为2，网络侧设备可以先将BWP的大小调整为3(2+1)，此时BWP的大小依旧小于配置的RBG的大小，则可以再次调整，即将BWP的大小调整为4(3+1)，此时BWP的大小等于配置的RBG的大小，可以完成调整。
在又一种可能的实现方式中，网络侧设备可以根据配置的RBG的大小，将BWP的大小调大。比如，配置的RBG的大小为4，BWP的大小为2，网络侧设备可以直接将BWP的大小调整为等于配置的RBG的大小，即直接将BWP的大小调整4。
在又一种可能的实现方式中，网络侧设备可以根据BWP的大小，将配置的RBG的大小调小。比如，配置的RBG的大小为4，BWP的大小为2，网络侧设备可以直接将配置的RBG的大小调整为等于BWP的大小，即直接将配置的RBG的大小调整2。
步骤506，网络侧设备向终端侧设备发送第四配置信息，第四配置信息包括调整后的BWP的大小和/或调整后的RBG的大小。
采用上述方法，网络侧设备在确定BWP的大小大于或等于配置的RBG的大小的情况下，可向终端侧设备发送第三配置信息，网络侧设备若确定BWP的大小小于配置的RBG 的大小则可以对BWP和配置的RBG进行调整，并向终端侧设备发送调整后的BWP的大小和调整后的RBG的大小，从而保证终端侧设备接收到的BWP的大小大于或等于为BWP配置的RBG的大小，满足终端侧设备不期待被配置BWP的大小小于为BWP配置的RBG的大小的需求。
上述方案主要描述了当BWP的大小小于配置的RBG的大小的情况下的具体实施方案。当BWP的大小大于或等于配置的RBG的大小时，可以根据所述公式1、公式2和公式3分别计算得到BWP i对应RBG个数、第一个RBG的大小和最后一个RBG的大小，从而确定出BWP对应的RBG，可以参见现有方案，不再赘述。
方案四
上述主要是基于RBG进行描述的，对于PRG来说，也存在类似的问题，比如网络侧设备为BWP i配置的PRG的大小可以为2或4，在此基础上，BWP i的大小小于为BWP i配置的PRG的大小(表示为P′)的情形可以包括：
情形1，P′＝2，
Figure PCTCN2019101217-appb-000093
情形2，P′＝4，
Figure PCTCN2019101217-appb-000094
情形3，P′＝4，
Figure PCTCN2019101217-appb-000095
情形4，P′＝4，
Figure PCTCN2019101217-appb-000096
由于确定BWP i对应的PRG的方法与确定BWPi对应的RBG的方法类似，因此，针对PRG的情形1至情形4可以参照上述表2至表5。
基于此，本申请实施例还提供方案四，包括：通信装置(可以为网络侧设备或终端侧设备)若确定BWP i的大小小于为BWP i配置的PRG的大小，则可以确定BWP i对应第一PRG，第一PRG的大小等于BWP i中被调度的PRB的个数。其中，被调度的PRB的个数可以等于BWP i包括的PRB的个数(即BWP i包括的全部PRB均被调度)，或者，也可以小于BWP i包括的PRB的个数(即BWP i包括的部分PRB均被调度)。
举个例子，若
Figure PCTCN2019101217-appb-000097
由于BWP i包括的1个PRB，该PRB即为被调度的PRB，此时，第一PRG的大小可以等于BWP i的大小。
再举个例子，若P＝4，
Figure PCTCN2019101217-appb-000098
P′＝4，此时，BWP i可以对应两个RBG。在一个示例中，网络侧设备可能只调度其中的一个RBG(比如调度第一个RBG，而未调度第二个RBG)，此种情形下，由于BWP i中被调度的PRB的个数为1，因此，第一PRG的大小可以等于1。在又一个示例中，网络侧设备可能调度两个RBG，此种情形下，由于BWP i中被调度的PRB的个数为2，因此，第一PRG的大小可以等于2，从而能够有效避免针对BWP i中的两个PRB分别使用不同的预编码进行处理，提高处理性能。
需要说明的是：上述方案一、方案二、方案三和方案四可以分别单独实施，或者也可以结合实施。比如，可以将方案一和方案四结合实施，或者将方案二和方案四结合实施，具体不做限定。

在一种可能的设计中，处理单元602具体用于：若确定BWP的大小小于为所述BWP配置的RBG的大小，且第三RBG的大小大于0，以及根据所述BWP的起始资源块索引、所述BWP的大小和配置的RBG的大小得到所述BWP对应的RBG的个数为1，则确定所 述BWP对应第三RBG。
在一种可能的设计中，通信单元603具体用于：在所述第二RBG中的前N个VRB映射的PRB上进行数据传输；其中，N为所述BWP包括的PRB的个数。

需要说明的是，本申请实施例中对单元(模块)的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。在本申请的实施例中的各功能模块可以集成在一个处理模块中，也可以是各个模块单独物理存在，也可以两个或两个以上模块集成在一个模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。
所述集成的模块如果以软件功能模块的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。基于这样的理解，本申请实施例的技术方案本质上或者说对现有技术做出贡献的部分或者该技术方案的全部或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中，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络侧设备等)或处理器(processor)执行本申请各个实施例所述方法的全部或部分步骤。而前述的存储介质可以为存储器等各种可以存储程序代码的介质。
