现有技术中有三种频域资源分配方法：Type 0、Type1和type2，以上三种方式指示的是带宽部分(Band Width Part，BWP)范围内的资源分配。
上述三种频域资源分配方法做简要介绍：
1、Type0。
Type0是通过位图(bitmap)的形式指示分配给UE的资源块组(Resource Block Groups，RBGs)，RBG是一组连续的虚拟资源块，RBG的大小通过高层配置的rbg-Size参数(指示config1或config2)和带宽部分(bandwidth part，BWP)的大小
Figure PCTCN2022133310-appb-000001
确定，如下表1(示出的是标准带宽部分的大小P)所示。

带宽部分的大小 配置1 配置2
1–36 2 4
37–72 4 8
73–144 8 16
145–275 16 16
位图的每个比特指示一个RBG，位图的bit长度等于N RBG，其中：
Figure PCTCN2022133310-appb-000002
其中，
Figure PCTCN2022133310-appb-000003

if
Figure PCTCN2022133310-appb-000008
带宽部分中出第一个RBG和最后一个RBG外，其它RBG的长度等于P。
2、Type1。
Type1是通过资源指示值(resource indication value，RIV)指示分配给UE在激活BWP内的起始RB(RB start)和长度(L RBs)，RIV的定义如下：
if
Figure PCTCN2022133310-appb-000009
then
Figure PCTCN2022133310-appb-000010
else
Figure PCTCN2022133310-appb-000011
where L RBs≥1and shall not exceed
Figure PCTCN2022133310-appb-000012
3、Type2。
对于μ＝0，资源分配字段的高6比特位通过RIV指示以m 0为起始索引的一组索引m 0+l。当0≤RIV<M(M+1)/2，对应起始交织(interlace)索引m 0和连续的交织索引个数L，其中l＝0,1,…,L-1，m 0∈{0,1,…,M-1}包含CPRB(common resource blocks){m,M+m,2M+m,3M+m，…}，M＝10，RIV定义为：
if
Figure PCTCN2022133310-appb-000013
then
RIV＝M(L-1)+m 0
else
RIV＝M(M-L+1)+(M-1-m 0)
当RIV≥M(M+1)/2，对应起始交织(interlace)索引m 0和l的取值集合，具体定义为表2。
表2
RIV-M(M+1)/2 m 0 l
0 0 {0,5}
1 0 {0,1,5,6}
2 1 {0,5}
3 1 {0,1,2,3,5,6,7,8}
4 2 {0,5}
5 2 {0,1,2,5,6,7}
6 3 {0,5}
7 4 {0,5}
对于μ＝1，此时M＝5，因为m0∈{0,1,…,M-1}，此时共有5个交织行，资源分配字段的高5bit通过位图的形式指示分配给UE的交织行，interlace 0to interlace M-1按照从高位到低位的顺序映射到位图。
对于μ＝0和μ＝1，通过SCS-SpecificCarrier确定载波带宽和位置，根据 IntraCellGuardBandsPerSCS中的GuardBand(包含startCRB和nrofCRBs对应

从上述内容可以看出，现有技术通过DCI动态通知载波信道或者BWP范围内的频域资源，当把载波信道或者BWP划分成多个sub-band分别用于上行和下行传输时，仍然采用上述全信道或者全BWP范围内的频域资源分配，并不支持单独用于上行和下行传输的频域资源指示，使得终端无法获得上行和下行传输的频域资源，同时还会出现资源分配字段对应的状态富余，导致DCI开销浪费的问题。
本申请实施例提供了一种频域资源确定的方法、终端、基站及存储介质，用以解决现有技术中终端难以确定上下行传输对应的频域资源的技术问题。
其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。
本公开实施例提供一种数据传输的方法，应用于终端，请参见图1，该方法的处理过程如下：
步骤101：确定在同一个频谱资源内，同一时刻用于上行和下行传输的频域资源；
步骤102：根据频域资源进行数据传输。
步骤101中的同一时刻可以是指相同的符号、时隙、子帧等，如同一符号中用于上行和下行传输的频域资源，即为同一时刻用于上行和下行传输的频域资源；同一时隙中用于上行和下行传输的频域资源，即为同一时刻用于上行和下行传输的频域资源；同一子帧中用于上行和下行传输的频域资源，即为同一时刻用于上行和下行传输的频域资源。
同一时刻用于上行和下行传输的频域资源可以是在全部时间单元有效，如在全部的符号、时隙、子帧或无线帧等有效；同一时刻用于上行和下行传输的频域资源也可以在部分时间单元有效，如在部分的符号、时隙、子帧或无线帧等有效，可以通过协议预定义，基站以配置的方式通知UE生效/失效的时间单元，从而解决对频谱资源划分为上下行资源之后，部分信道/信号无法传输的问题，例如SSB。
在本公开提供的实施例中，同一时刻用于上行和下行传输的频域资源可以分布在同一频谱资源内的同一频点，也可以是上行和下行频域资源的间隔小于某一门限值。上述频谱资源包括TDD band、用于上行的FDD band、用于下行的FDD band、载波(carrier)、BWP或者用于部署全双工的band。
例如，上行和下行频域资源所分布的频谱资源为TDD band时，上行和下行频域资源可以分布在TDD band内的同一频点，也可以分布在不同频点，且不同频点间的频点间隔小于一某一门限值；同理，上行和下行频域资源所分布的频谱资源为用于上行的FDD band、用于下行的FDD band、载波carrier、BWP或者用于部署全双工的band时，上行和下行频域资源分布在对应频谱资源内的同一频点，或不同频点，且不同频点间的频点间隔小于某一门限值。
上述同一频谱资源可以是3GPP有关标准中定义的单独的NR工作频段， 如3GPP TS38.101v h.4.0协议版本或TS38.104v h.4.0协议版本中定义的单独的NR工作频段。如表3所示，某标准中定义的FR1中的NR工作频段。

Figure PCTCN2022133310-appb-000025
可选的，上述频谱资源的宽度需要满足一定的条件，比如频谱资源的宽度大于或等于5MHz。通过将频谱资源的宽度设置为大于或等于5MHz，可以在频谱资源进行上下行资源划分后，满足在上行资源上承载随机接入信道(Random Access Channel，RACH)信道和在下行资源上承载SSB的要求。例如频谱资源为BWP，支持上下行子带划分的BWP宽度需要大于或等于5MHz。
可选的，本实施例中上行传输的频域资源的宽度也需要满足一定的条件，比如上行传输的频域资源的宽度大于或等于6个RB。通过将上行传输的频域资源的宽度设置为大于或等于6个RB，可以使上行传输的频域资源满足承载RACH信道等的要求。
在本公开提供的实施例中，同一时刻用于上行和下行传输的频域资源， 可以只有一个上行和下行传输的频域资源，也可以有多个上行和/或下行传输的频域资源。上行和下行传输的频域资源相互不重叠，若有多个上行和/或下行传输的频域资源，则任意两个相互不重叠。
在本公开提供的实施例中，可以通过预定义方式、半静态方式或动态方式，确定在同一个频谱资源内，同一时刻用于上行和下行传输的频域资源。
第一种：采用预定义方式。
若采用预定义方式，确定在同一个频谱资源内，同一时刻用于上行和下行传输的频域资源，可以通过下列方式实现：
根据预设的上下行资源划分方式，获取同一时刻用于上行和下行传输的频域资源；其中，频域资源是根据预先规定的划分方式对频谱资源划分得到的。
上述预设的上下行资源划分方式可以是相关通信协议中预先规定的划分方式，如在未来的通信协议中规定了上下行传输使用的频域资源的划分规则，基站或终端在使用上行和下行传输的频域资源时，可以根据预设的上下行资源划分方式，直接获取同一时刻用于上行和下行传输的频域资源。
如，规定频谱资源内的第X个RB至第Y个RB为上行传输的频域资源。例如，请参见图2为本公开实施例提供的一种预设的上下行资源划分方式的示意图。图2中大小为5MHz的频谱资源，示出了第0个RB～第24个RB，在相关通信协议中预先规定了中间的第10个RB至第14个RB为上行传输对应的频域资源(即上行频域资源)，剩余频域资源为下行传输对应的频域资源(即下行频域资源)或者部署TDD模式。上述上行频域资源与下行频域资源互相不交叠。
又如请参见图3为本公开实施例提供的另一种预设的上下行资源划分方式的示意图。图3是大小为10MHz的频谱资源，示出了第0个RB～第51个RB，相关协议中预先规定了中间的第22个RB至第29个RB为上行传输对应的频域资源，其余频域资源可以用于静态/动态TDD部署。
根据上述预设的上下行资源划分方式，终端可以确定出同一时刻用于上 行和下行传输的频域资源，进而根据同一时刻用于上行和下行传输的频域资源进行数据传输。
此处的上行和下行传输资源可以是应用于某一个终端，即该终端在同一时刻分别在上行和下行传输的频域资源上面传输上行和下行；也可以是应用于不同的终端，即同一时刻，终端1用上行传输的频域资源传输上行数据，终端2用下行传输的频域资源接收下行数据。
在本公开提供的实施例中，频谱资源的两侧还可以预留部分资源，这部分资源不做上行和下行传输的频域资源划分。这样可以抑制相邻运营商之间的干扰。
对于同一时刻用于上行和下行传输的频域资源中只有一个上行和下行传输的频域资源的情况，终端可以直接使用对应的频域资源。
例如，终端根据预设的上下行资源划分方式，确定在同一个频谱资源内，同一时刻用于上行和下行传输的频域资源包括上行频域资源为第6个RB，以及下行频域资源为第8个RB，终端在需要进行上行数据传输时，可以根据采用预定义方式确定的同一时刻用于上行和下行传输的频域资源(上行：第6个RB，下行：第8个RB)，直接使用第6个RB进行上行数据传输；终端在需要进行下行数据接收时，可以直接使用第8个RB进行下行数据接收。
上述频域资源的粒度可以是RB级别的，也可以是RB组级别的，还可以是载波级别的等。用于上行/下行传输的频域资源的粒度包括以6个资源块RB为单位，用于上行和/或下行传输的频域资源的起始资源块(Resource Block，RB)索引为6的整数倍。比如核心集(又称控制资源集，CORESET)的频域资源是6个RB的倍数，以及CORESET的起始RB索引是6的整数倍，因此，用于下行传输的频域资源的粒度以6个RB为单位，同时用于下行传输的频域资源的起始RB索引为6的整数倍，能够有效的匹配控制信道的设计。同时，为了保持用于上行传输和下行传输的频域资源的划分粒度一致，上行传输的频域资源的粒度也以6个RB为单位，以及上行传输的频域资源的起始RB索引也为6的整数倍。
在本公开提供的实施例中，根据预设的上下行资源划分方式，获取的同一时刻用于上行和下行传输的频域资源，可以在基站指示双工切换时生效，也可以在基站指示双工切换后的第k个符号或时隙生效，k为整数，所述k值可以通过DCI配置、RRC信令通知或预定义。
第二种：采用半静态方式。
若采用半静态方式，确定在同一个频谱资源内，同一时刻用于上行和下行传输的频域资源，可以通过下列方式实现：
接收无线资源控制(Radio Resource Control，RRC)信令，RRC信令用于在频谱资源内配置同一时刻用于上行和下行传输的频域资源；根据RRC信令，确定同一时刻用于上行和下行传输的频域资源。
例如，基站通过RRC信令通知终端，在TDD band内，确定的同一时刻用于上行和下行传输的频域资源包括：上行频域资源为TDD band内的第M个RB至第N个RB，和/或下行频域资源为TDD band内的第P个RB至第Q个RB，其中M、N、P和Q为非负整数，N大于M，Q大于P。终端接收到上述RRC信令后，可以据此确定TDD band内，同一时刻用于上行和下行传输的频域资源包括：上行频域资源为TDD band内的第M个RB至第N个RB，和/或下行频域资源为TDD band内的第P个RB至第Q个RB。
同理，当频谱资源为用于上行的FDD band，或用于下行的FDD band，或载波carrier，或BWP或者用于部署全双工的band时，处理方式与上述频谱资源为TDD band时类似，故不再赘述。
在本公开提供的实施例中，RRC信令用于配置小区级或终端组级或终端级对应的频域资源。即基站在配置同一时刻用于上行和下行传输的频域资源时，可以按小区级或UE组级，或UE级进行配置。配置的同一时刻用于上行和下行传输的频域资源，可以是在一个频带或一个载波或一个BWP的范围内，基站通过RRC信令，将配置的小区级或终端组级或终端级的频域资源发送给终端。
例如，基站可以在同一频谱资源内，为其所辖的每个小区配置同一时刻 用于上行和下行传输的频域资源，也可以为每个UE组配置同一时刻用于上行和下行传输的频域资源，还可以为每个UE配置同一时刻用于上行和下行传输的频域资源。基站在完成上述配置后，可以通过RRC信令通知终端上述配置结果。终端在接收到上述RRC信令后，根据RRC信令，确定同一时刻用于上行和下行传输的频域资源。在本公开提供的实施例中，频谱资源的两侧还可以预留部分资源，这部分资源不做上行和下行传输的频域资源划分。这样可以抑制相邻运营商之间的干扰。
如，对于上行频域资源为某个频谱资源的第M个RB～第N个RB，和下行频域资源为频谱资源的第P个RB～第Q个RB，可以限制M和P大于K，其中K大于或等于频谱资源的第一个RB的编号，P和Q小于频谱资源的最大RB的编号。如对于5MHz信道对应的频谱资源，规定其中第2个RB至第6个RB为上行频域资源，第8至第12个RB为下行频域资源，这样在上行频域资源的两端有第0～第1个RB、第7个RB这部分资源不做上行和下行传输的频域资源划分，在下行频域资源的两端有第7个RB、第13个RB这部分资源不做上行和下行传输的频域资源划分，因此可以在上行频域资源和下行频域资源的两侧都预留部分资源形成保护间隔，从而可以抑制上下行传输方向不一致导致的运营商之间的干扰。
第三种：动态方式。
当采用上述预定义或半静态的方式，确定在同一个频谱资源内，同一时刻用于上行和下行传输的频域资源包括多个用于上行传输和/或用于下行传输的频域资源时，基站通过DCI通知终端多个用于上行传输和/或用于下行传输的频域资源中使用的一个或多个用于上行传输和/或用于下行传输的频域资源。此时，终端确定在同一个频谱资源内，同一时刻用于上行和下行传输的频域资源包括多个用于上行传输和/或用于下行传输的频域资源，可以通过下列方式实现：
接收下行控制信息DCI，DCI用于通知终端使用多个用于上行传输和/或用于下行传输的频域资源中的一个或多个用于上行传输和/或用于下行传输的 频域资源；根据DCI，确定一个或多个用于上行传输和/或用于下行传输的频域资源。当终端需要进行数据传输时，可以根据DCI确定的一个或多个用于上行传输和/或用于下行传输的频域资源进行数据传输。
不管使用上述何种方式确定在同一个频谱资源内，同一时刻用于上行和下行传输的频域资源，在使用同一时刻用于上行和下行传输的频域资源时，可以只使用其中一个传输方向的频域资源、也可以同时使用两个传输方向的频域资源或者不使用任意一个传输方向的频域资源。
例如，在TDD band内，确定的同一时刻用于上行和下行传输的频域资源包括一个上行频域资源和一个下行频域资源，基站可以使用下行频域资源向终端1发送下行数据，同时使用上行频域资源接收终端2发送的上行数据，对于终端1而言其使用下行频域资源接收该基站发送的下行数据，对终端2而言，使用上行频域资源向该基站发送上行数据。若在当前时刻只有终端1需要接收该基站的下行数据，没有终端发送上行数据，则基站只用下行频域资源向终端1发送下行数据。若在某一时刻，既没有上行数据传输也没有下行数据传输，此时不使用任意一个传输方向的频域资源。
又如，在BWP内，确定的同一时刻用于上行和下行传输的频域资源包括3个上行频域资源和3个下行频域资源，基站通过DCI通知终端1使用其中的上行频域资源2和下行频域资源2进行数据传输，还通过DCI通知终端2使用上行频域资源3和下行频域资源3进行数据传输，在某一时刻，终端1需要向基站发送上行数据，终端2需要接收基站发送的下行数据，则终端1使用上行频域资源2向基站发送上行数据，同时终端2使用下行频域资源3接收基站下行数据。
动态方式的方案介绍如下：
方案一、基于预定义的动态方式：
若采用预定义方式，确定在同一个频谱资源内，同一时刻用于上行和下行传输的频域资源有多个时，基站通过DCI通知终端多个用于上行传输和/或用于下行传输的频域资源中的一个或多个用于上行传输和/或用于下行传输的 频域资源。
通过上述预定义的方式，将同一个频谱资源划分成多个上/下行子带，子带的大小和个数决于频谱资源的大小或者网络/基站配置。基站通过DCI动态配置UE具体使用的子带。
例如，对于频谱资源的大小大于或等于L个RB，子带的大小(size)为k1；对于频谱资源的大小小于或等于L个RB，子带的大小为k2；或者网络/基站通过RRC/DCI配置子带的大小。子带的个数(记为num)通过频谱资源的大小和子带的大小(记为sub-band size)确定，即num＝ceil(频谱资源的带宽/sub-band size)，ceil为向上取整的函数，/为除法符号。当频谱资源为BWP时，上述公式中频谱资源的带宽为BWP的大小。进一步，还可以将频谱资源划分成多个区间(如划分为3个或3个以上区间)，每个区间定义不同的子带大小，每个区间的子带大小可以是预定的、RRC配置的或者DCI配置的。每个区间的子带个数分别根据每个区间的子带大小计算，计算方法和上述不分区间的情况相同，此处不再赘述。
此外，在频谱资源的两侧还可以预留部分资源，不做上行和下行传输的频域资源划分。如，可以在频谱资源的两侧预留z个RB不做上行和下行传输的频域资源划分，z为自然数。如，可以在频谱资源的两侧分别预留z1和z2个RB不做上行和下行传输的频域资源划分，z1和z2为自然数，z1和z2可以不同。
请参见图4为本公开实施例提供的一种子带划分示意图，BWP的第0-第1个RB及第22-24个RB作为预留的部分频域资源，其它RB划分为sub-band。每个sub-band包括5个RB，共划分为4个sub-band：DL-SB0(第2-第6个RB)、UL-SB0(第7-第11个RB)、DL-SB1(第12-16个RB)、UL-SB1(第17-21个RB)，这样通过在BWP的两侧预留部分不做上行和下行传输的频域资源划分的RB来抑制相邻运营商的干扰。
此外，还可以在上述预留RB上面部署静态或动态TDD，来保持相邻运营商之间的上下行传输方向对齐，实现抑制相邻运营商之间的交叉干扰。
在本公开提供的实施例中，多个上行和下行频域资源中上行频域资源和下行频域资源具有关联关系，这种关联关系可以是上行频域资源和下行频域资源成对配置的关系，如图4中UL-SB0和DL-SB 0可以组成子带对(sub-band pair)来形成上述关联关系。基站可以成对的配置子带对，如，上行配置了UL-SB0，下行便相应的被配置为DL-SB0，不再专门配置下行子带，反之亦可；当存在多个子带对时，例如UL-SB0和DL-SB 0组成子带对0(记为sub-band pair 0)，UL-SB1和DL-SB1组成子带对1(记为sub-band pair 1)，基站可以通过DCI指示子带对的编号来通知终端具体使用的上行子带和下行子带。终端根据接收到的DCI可以确定其具体使用的子带对的编号，进而根据该编号选用对应的子带进行数据传输。
基站通过DCI动态通知终端使用预定义的子带集合中的具体使用的某个子带，可以通过调度PDSCH或PUSCH的DCI通知，在上述DCI中定义专门的指示字段，如在上述DCI中定义一个比特长度为1的字段指示图4中2个上行子带或下行子带中的某一个。
基站通过DCI动态通知终端使用预定义的子带集合中的具体使用的某个子带，还可以在DCI种使用频域资源分配字段的第X比特位进行指示，如使用频域资源分配字段的最高位比特位或最低比特位指示图4中2个上行或下行子带中的一个。
DCI中具体用多少个比特位指示终端实际使用的上行子带或下行子带，可以根据预定义中包含的上行子带的总数量或下行子带的总数量确定。
基站通过DCI动态通知终端使用预定义的子带集合中的具体使用的某个子带，还可以用配置上行和/或下行频域资源的DCI通知。在该DCI中可以指示终端使用预定义的子带集合中的某个子带，上述指示可以立即生效，也可以在指定的间隔时长后生效，如终端在时隙(slot)n收到上述DCI的指示，即刻更新上行/下行传输的sub-band，即在slot n传输的上行/下行便采用该DCI中指示的sub-band。也可以根据指定的间隔时长(如间隔offset个时隙)，在n+offset时隙更新上行/下行传输的sub-band，即在n+offset时隙传输的上行/ 下行采用该DCI中指示的sub-band。上述offset的取值与终端的射频能力(即切换sub-band所需要的时间)有关系，可以给不同能力的终端定义不同的offset。基站可以根据实现算法判断UE是否成功接收该DCI。对于该DCI调度下行sub-band，sub-band生效后，基站可以根据在该sub-band上面发送的传输块对应的HARQ-ACK反馈情况决定是否重新发送该DCI，例如在连续发送的K个传输块对应的HARQ-ACK全部为NACK，则基站决定重新发送该DCI。对于该DCI调度的是上行sub-band，当sub-band生效后，基站可以根据在该sub-band上面接收的传输块的情况决定是否重新发送该DCI，例如连续M个传输块接收失败，则基站决定重新发送该DCI。终端在成功接收上述DCI后，根据DCI通知的频域资源进行数据传输。
方案二、基于半静态配置的动态方式：
基站确定在同一个频谱资源内，同一时刻用于上行和下行的多个频域资源后，通过RRC信令将同一时刻用于上行和下行的多个频域资源发送给终端，并通过DCI动态通知终端使用的是多个用于上行传输和/或用于下行传输的频域资源中的一个或多个。
基站通过RRC信令配置某个频谱资源的上行子带集合包含{UL-SB0，UL-SB1，……，UL-SB n}和下行子带集合包含{DL-SB0，DL-SB1，……，DL-SB n}组成同一时刻用于上行和下行传输的频域资源；其中，UL-SB0包含频谱资源内的第X0至第Y0个RB,UL-SB1包含频谱资源内的第X1至第Y1个RB，UL-SBn包含频谱资源内的第Xn至第Yn个RB，X0<Y0<X1<Y1…<Xn<Yn；DL-SB0包含频谱资源内的第P0至第Q0个RB，DL-SB1包含频谱资源内的第P1至第Q1个RB，DL-SBn包含频谱资源内的第Pn至第Qn个RB，其中P0<Q0<P1<Q1…<Pn<Qn，n为正整数，可选的，n的大小可以取决于频谱资源的大小。X0，X1，Xn，Y0，Y1，Yn，P0，P1，Pn，Q0，Q1，Qn为非负整数。基站可以通过DCI动态通知终端其使用的子带(如下行传输使用DL-SB1子带，上行传输使用UL-SB1)。终端根据DCI通知的频域资源进行数据传输。
在上述上行子带集合和下行子带集合的两端可以设置部分资源不做上行和下行传输的频域资源划分，具体在设置时可以限制X0和/或P0大于α，Yn和Qn与频谱资源内最大RB索引之差大于β，其中α和β大于等于0。所述α和β可以是协议中规定的、RRC配置的或者DCI配置的。如对于5MHz频谱资源(包括第0个RB～第24个RB)，上行子带集合包含{UL-SB0，UL-SB1}，下行子带集合包含{DL-SB0，DL-SB1}，各个子带对应的RB如下图5所示，图5为本公开实施例提供的另一种子带划分示意图，第2个RB(即P0)大于1，第22个RB(即Yn)与最大RB索引(即24)之差为2(大于1)。通过在频谱资源两侧预留RB，在预留RB范围内部署静态TDD/动态TDD，可以起到抑制相邻运营商之间的干扰作用。
上述上行子带集合与下行子带集合中的上行子带和下行自带可以具有绑定或关联关系，如UL-SB0和DL-SB 0组成子带对(sub-band pair)，基站可以为终端成对配置上行子带和下行子带(如终端使用的上行子带配置为UL-SB0，则下行子带即为DL-SB0，反之亦然)。可选的，终端也可以将上行子带和下行子带组成子带对(如将UL-SB1和DL-SB1组成子带对1)，基站通过DCI指示子带对编号，终端通过DCI指示的子带对编号可以确定其实际使用的上行子带和下行子带，进而根据DCI通知的上行子带和下行子带进行数据传输。
基于基站配置的同一时刻用于上行和下行传输的多个频域资源后，基站可以通过调度PDSCH/PUSCH的DCI中定义专门的频域资源配信息对应的字段(如频域资源分配字段、子带指示字段、子带分配字段)将配置的上述多个频域资源中的某一个或多个发送给终端，如，针对DCI Format 0_1/Format0_2/Format 1_1/Format 1_2，定义新的子带分配字段，专门用于指示UE的上行子带或下行子带。终端接收到调度PDSCH/PUSCH的DCI后，根据调度PDSCH/PUSCH的DCI中频域资源分配信息对应的字段，确定一个或多个用于上行传输和/或用于下行传输的频域资源进行数据传输。
基站还可以用调度PDSCH/PUSCH的DCI中的频域分配信息对应字段的 高或低X个bit(s)位指示终端实际使用的子带的位置。如，针对DCI Format0_1/Format 0_2/Format 1_1/Format 1_2，利用频域资源分配字段的高/低X位bit(s)指示UE的上行子带或下行子带。
在调度PDSCH/PUSCH的DCI中，还可以通过预定义的方式确定基站分配给终端的上行子带或下行子带，如对于DCI Format 0_0/DCI Format 1_0中的频域分配字段没有指示子带位置，可以预定义RRC配置的上行或下行子带集合中的第一个或最后一个上行或下行子带为基站分配给终端的上行或下行子带。这样就无须使用DCI中的频域分配字段通知终端使用的频域资源，从而可以节约信令开销。
可选的，基站通过调度PDSCH/PUSCH的DCI中频域资源分配字段的全部或部分比特，通知终端实际使用的频域资源，如可以用Type0/Type1/Type2方法动态通知终端具体使用的频域资源，对于Type2，可以预定义M为除了5和10之外的其它正整数值。
基站还可以用配置上行和/或下行频域资源的DCI通知终端使用的频域资源的具体位置，如新定义的DCI格式用于指示RRC配置的子带集合中的某个子带，终端在可以在收到该DCI后即时更新所使用的子带，也可以在收到DCI后的一段时间后再更新所使用的子带。如终端在时隙n收到新定义的DCI通知上行传输使用子带1，即刻更新上行传输的子带为子带1；或，终端在时隙n收到新定义的DCI通知上行传输使用子带1，可以在间隔offset个时隙后更新上行传输的子带为子带1，即在第n+offset个时隙更新上行传输的子带为子带1。上述offset可以根据终端的射频能力(如切换子带所需要的时长)确定，可以为具有不同射频能力的终端设置不同的offset。所述offset为预定义的、RRC配置的或者DCI配置的。
可选的，基站可以根据实现算法判断UE是否成功接收该DCI。对于该DCI调度下行sub-band，sub-band生效后，基站可以根据在该sub-band上面发送的传输块对应的HARQ-ACK反馈情况决定是否重新发送该DCI，例如在连续发送的K个传输块对应的HARQ-ACK全部为NACK，则基站决定重新 发送该DCI。对于该DCI调度的是上行sub-band，当sub-band生效后，基站可以根据在该sub-band上面接收的传输块的情况决定是否重新发送该DCI，例如连续M个传输块接收失败，则基站决定重新发送该DCI。
可选的，基站也可以根据UE对该DCI正确接收反馈的ACK信息确定UE成功接收该DCI。可选的，该DCI生效时间可以为接收到该DCI的时刻；也可以为反馈正确接收该DCI之后生效，即基站收到该DCI正确接收的反馈之后，基站再在该DCI通知的子带上面进行数据传输。通过该DCI配置子带的生效时长，可以通过高层信令配置具体时长，也可以通过再次配置子带来更新该子带配置。
在本公开提供的实施例中，通过确定在同一个频谱资源内，同一时刻用于上行和下行传输的频域资源，使终端能够确定同一时刻用于上下行传输的频域资源，进而进行数据传输。此外，在本公开提供的实施例中，由于基站可以通过DCI动态调度上行或下行频域资源，相较于现有技术中通过全信道带宽内的动态调度方式，可以节约DCI开销，提高DCI传输的可靠性。
基于同一发明构思，本公开实施例还提供一种数据传输的方法，应用于基站，该方法包括：
确定在同一个频谱资源内，同一时刻用于上行和下行传输的频域资源；根据所述频域资源进行数据传输。
上述频谱资源包括TDD band、用于上行的FDD band、用于下行的FDD band、载波carrier、BWP或者用于部署全双工的band。对于上述同一时刻、同一时刻用于上行和下行传输的频域资源的相关解释可以参加终端侧中的描述，在此不做赘述。
同一时刻用于上行和下行传输的频域资源可以是在全部时间单元有效，如在全部的符号、时隙、子帧或无线帧等有效；同一时刻用于上行和下行传输的频域资源也可以在部分时间单元有效，如在部分的符号、时隙、子帧或无线帧等有效，可以通过协议预定义，基站以配置的方式通知UE生效/失效的时间单元，从而解决对频谱资源划分为上下行资源之后，部分信道/信号无 法传输的问题，例如SSB。
可选的，上述频谱资源的宽度需要满足一定的条件，比如频谱资源的宽度大于或等于5MHz。通过将频谱资源的宽度设置为大于或等于5MHz，可以在频谱资源进行上下行资源划分后，满足在上行资源上承载RACH信道和在下行资源上承载SSB的要求。例如频谱资源为BWP，支持上下行子带划分的BWP宽度需要大于或等于5MHz。
可选的，本实施例中上行传输的频域资源的宽度也需要满足一定的条件，比如上行传输的频域资源的宽度大于或等于6个RB。通过将上行传输的频域资源的宽度设置为大于或等于6个RB，可以使上行传输的频域资源满足承载RACH信道等的要求。
在本公开提供的实施例中，同一时刻用于上行和下行传输的频域资源，可以只有一个上行和下行传输的频域资源，也可以有多个上行和/或下行传输的频域资源。上行和下行传输的频域资源相互不重叠，若有多个上行和/或下行传输的频域资源，则任意两个相互不重叠。
与终端侧类似的，基站侧也可以通过预定义方式、半静态方式或动态方式，确定在同一个频谱资源内，同一时刻用于上行和下行传输的频域资源，具体如下：
采用预定义的方式：
确定在同一个频谱资源内，同一时刻用于上行和下行传输的频域资源，可以通过下列方式实现：
根据预设的上下行资源划分方式，获取同一时刻用于上行和下行传输的频域资源；其中，所述频域资源是根据预先规定的划分方式对所述频谱资源划分得到的。
上述预设的上下行资源划分方式可以是相关通信协议中预先规定的划分方式，如在未来的通信协议中规定了上下行传输使用的频域资源的划分规则，基站或终端在使用上行和下行传输的频域资源时，可以根据预设的上下行资源划分方式，直接获取同一时刻用于上行和下行传输的频域资源。具体的实 施例可以参见终端侧的描述，在此不再赘述。
发明提供的实施例中，频谱资源的两侧还可以预留部分资源，这部分资源不做上行和下行传输的频域资源划分。这样可以抑制相邻运营商之间的干扰。
对于同一时刻用于上行和下行传输的频域资源中只有一个上行和下行传输的频域资源的情况，基站可以直接使用对应的频域资源。
上述频域资源的粒度可以是RB级别的，也可以是RB组级别的，还可以是载波级别的等。用于上行/下行传输的频域资源的粒度包括以6个资源块RB为单位，用于上行和/或下行传输的频域资源的起始RB索引为6的整数倍。比如CORESET的频域资源是6个RB的倍数，以及CORESET的起始RB索引是6的整数倍，因此用于下行传输的频域资源的粒度以6个RB为单位，同时用于下行传输的频域资源的起始RB索引为6的整数倍，能够有效的匹配控制信道的设计。同时，为了保持用于上行传输和下行传输的频域资源的划分粒度一致，上行传输的频域资源的粒度也6个RB为单位，以及上行传输的频域资源的起始RB索引也为6的整数倍。
在本公开提供的实施例中，根据预设的上下行资源划分方式，获取的同一时刻用于上行和下行传输的频域资源，可以在基站指示双工切换时生效，也可以在基站指示双工切换后的第k个符号或时隙生效，k为整数，所述k值可以通过DCI配置、RRC信令通知或预定义。
采用半静态的方式：
确定在同一个频谱资源内，同一时刻用于上行和下行传输的频域资源，即由基站确定在同一个频谱资源内，同一时刻用于上行和下行传输的频域资源，之后基站通过RRC信令，将上述频域资源发送给终端。终端接收到上述RRC信令后，根据RRC信令，确定在同一个频谱资源内，同一时刻用于上行和下行传输的频域资源。这样双方就能根据上述频谱资源进行数据传输。
一种可能的实施方式，通过无线资源控制RRC信令，将频域资源发送给终端，还可以通过下列方式实现：
RRC信令是小区级或终端组级或终端级的；通过RRC信令，将小区级或终端组级或终端级的频域资源发送给终端。
基站在配置同一时刻用于上行和下行传输的频域资源时，可以按小区级或UE组级，或UE级进行配置。配置的同一时刻用于上行和下行传输的频域资源，可以是在一个频带或一个载波或一个BWP的范围内，基站可以通过RRC信令通知终端同一时刻用于上行和下行传输的频域资源。
基站可以在同一频谱资源内，为其所辖的每个小区配置同一时刻用于上行和下行传输的频域资源，也可以为每个UE组配置同一时刻用于上行和下行传输的频域资源，还可以为每个UE配置同一时刻用于上行和下行传输的频域资源。基站在完成上述配置后，可以通过RRC信令通知终端上述配置。
在本公开提供的实施例中，频谱资源的两侧还可以预留部分资源，这部分资源不做上行和下行传输的频域资源划分。这样可以抑制相邻运营商之间的干扰。
采用动态的方式：
基站先确定在同一个频谱资源内，同一时刻用于上行和下行传输的频域资源，该频域资源包括多个用于上行传输和/或用于下行传输的频域资源；之后再从多个用于上行传输和/或用于下行传输的频域资源中确定终端使用的一个或多个用于上行传输和/或用于下行传输的频域资源；并通过下行控制信息DCI，将一个或多个用于上行传输和/或用于下行传输的频域资源信息发送给终端。
上述基站确定在同一个频谱资源内，同一时刻用于上行和下行传输的频域资源可以是通过自定义的方式或半静态的方式确定的。具体动态方式的方案介绍如下：
基于预定义的动态方式：
基站根据预设的上下行资源划分方式，获取同一时刻用于上行和下行传输的频域资源；其中，频域资源是根据预先规定的划分方式对所述频谱资源划分得到的，该频域资源包括多个用于上行传输和/或用于下行传输的频域资 源，基站从多个用于上行传输和/或用于下行传输的频域资源中确定终端使用的一个或多个用于上行传输和/或用于下行传输的频域资源，通过DCI将一个或多个用于上行传输和/或用于下行传输的频域资源的位置信息发送给终端。
终端接收到上述DCI后，根据预设的上下行资源划分方式，获取同一时刻用于上行和下行传输的频域资源；其中，频域资源是根据预先规定的划分方式对所述频谱资源划分得到的，该频域资源包括多个用于上行传输和/或用于下行传输的频域资源(即采用预定义的方式确定同一时刻用于上行和下行传输的频域资源)，根据DCI中通知的位置信息，从多个用于上行传输和/或用于下行传输的频域资源中确定一个或多个用于上行传输和/或用于下行传输的频域资源。
基于半静态的动态方式：
基站通过RRC信令，将确定的同一时刻用于上行和下行传输的频域资源发送给终端，该频域资源包括多个用于上行传输和/或用于下行传输的频域资源。之后，基站根据从多个用于上行传输和/或用于下行传输的频域资源中确定终端使用的一个或多个用于上行传输和/或用于下行传输的频域资源，通过DCI将一个或多个用于上行传输和/或用于下行传输的频域资源的位置信息发送给终端。
终端接收到上述DCI后，根据上述RRC信令，确定同一时刻用于上行和下行传输的频域资源。并根据DCI中通知的位置信息，从多个用于上行传输和/或用于下行传输的频域资源中确定一个或多个用于上行传输和/或用于下行传输的频域资源。
具体的实施例可以参见终端侧对应实施例的描述，在此不再赘述。
在本公开提供的实施例中，通过下行控制信息DCI，将一个或多个用于上行传输和/或用于下行传输的频域资源发送给终端，可以通过下列方式实现：
通过DCI的频域资源分配信息，将一个或多个用于上行传输和/或用于下行传输的频域资源送给终端。上述频域资源分配信息包括频域资源分配字段、子带指示字段，或子带分配字段指示。
可选地，多个上行和下行频域资源中上行频域资源和下行频域资源具有关联关系，这种关联关系可以是上行频域资源和下行频域资源成对配置的关系。具体实施例可以参见终端侧中的介绍，在此不再赘述。
可选地，DCI为用于调度PDSCH或PUSCH的DCI，或用于配置上行和/或下行频域资源的DCI。
基站侧动态方式的方案介绍可以参见终端侧的介绍，在此不再赘述。
