Description

数据传输方法、装置、芯片、芯片模组及存储介质
本申请要求于2022年08月12日提交中国国家知识产权局、申请号为202210970208.0、发明名称为“数据传输方法、装置、芯片、芯片模组及存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种数据传输方法、装置、芯片、芯片模组及存储介质。
背景技术
由于时分复用(time division duplex，TDD)系统上下行时隙配比的限制，导致TDD系统的传输时延较大。为了降低基站的实现复杂度，一个TDD载波的所有频域资源在同一时刻的传输方向需相同，同为上行或下行，即一个TDD载波同一时刻不同频域资源的上下行时隙配比不能灵活配置。
随着业务的多元化，尤其是考虑垂直行业的业务需求，不同业务对上下行的传输需求不同，单一的上下行时隙配比不能满足不同业务的需求。基于以上两点，同时考虑基站实现复杂度，提出了子带全双工(sub-band full duplex，SBFD)的解决方案：在基站侧，利用子带的存在，在频域划分上下行传输，在保证同一时刻能进行上下行传输的同时，利用频分减少了干扰，降低了基站的复杂度，更易于实现，成为了标准化的热点。针对子带全双工，可以有不同的形式，如图1a-至图1d所示。其中，t表示时间，f表示频率，D表示下行(downlink)，U表示上行(uplink)。

需要说明的是，本申请实施例中的术语“系统”和“网络”可被互换使用。
首先介绍一下目前的频域资源分配：
1.1频域资源分配
下行控制信息(downlink control information，DCI)中的频域资源分配字段“Frequency domain resource assignment”会指示物理下行共享信道(physical downlink shared channel，PDSCH)/物理上行共享信道(physical uplink shared channel，PUSCH)的频域资源分配。PDSCH/PUSCH频域资源分配分为Type 0和Type 1两种类型。其中，Type 0支持非连续的分配，从而可以获得频率分集增益；Type 1支持连续资源分配，可减少该字段所需的比特数。
1.1.1Type 0资源分配
非连续资源分配类型采用资源块组(resource block group，RBG)为基本单位，由P个连续的物理资源块(physical resource block，PRB)组成，如下表1所示。表1中BWP大小是指BWP中包含的PRB的个数，RBG中包含的PRB的个数可以称为RBG的大小。一个RBG中包括的PRB的具体个数由高层参数“rbg-Size”和部分载波带宽(bandwidth part，BWP)的带宽决定。“rbg-Size”决定了P的取值是对应配置1(Configuration 1)还是配置2(Configuration2)。
表1常规RBG大小P
如表1的第1行所示，BWP包括最多36个PRB、且采用配置1时，一个RBG中包括2个PRB；采用配置2时，一个RBG中包括4个PRB。
那么，一个BWP i内的RBG数量NRBG为：
其中，为BWP i内包含的PRB个数；
第一个RBG的大小
如果最后一个RBG的大小
否则，
其它RBG的大小均为P。
其中，为BWP起始公共资源块(common resource block，CRB)的索引。
以PDSCH资源分配为例说明，PUSCH类似：
在Type 0资源分配类型下，“Frequency domain resource assignment”会作为一个位图(bitmap)来指示哪些RBG是分配给PDSCH的：一个bitmap中的每个比特代表一个RBG，最高比特对应RBG0，以此类推。比特为1表示该RBG分配给PDSCH，比特为0表示该RBG不分配给PDSCH，这样可以灵活地调度资源。一般情况下，RBG可以直接映射到相同编号的物理资源上。
1.1.2Type 1资源分配
在Type 1中，频域资源分配字段不通过bitmap指示，而是会指示一个资源指示值(resource indicator value，RIV)值，终端设备通过该值计算PDSCH的起始的虚拟资源块(virtual resource block，VRB)和连续的VRB个数，计算公式如下：
如果
否则，
其中，LRBs≥1且不会超过
其中，LRBs表示连续的VRB个数；表示BWP内包含的VRB个数；RBstart表示起始的VRB索引。
对于Type1资源，在进行数据的交织映射时有以下规定：
1.1.2.1交织资源块簇(resource-block bundle)
在BWP内，有两种资源块(resource block，RB)：VRB和PRB。其中，VRB是虚拟资源块，PRB是实际的物理资源块。上述PDSCH和PUSCH的频域资源分配都是以VRB为单位，然后将VRB映射到PRB上。映射方式分为交织映射和非交织映射。BWP内VRB和PRB的编号都是从BWP的起始位置编号为0开始增序排列。
非交织映射是指编号为n的VRB直接映射到编号为n的PRB上；
交织映射是指编号为n的VRB映射到编号为f(n)的PRB上，其中，f()是交织器函数。
PUSCH和PDSCH的另一个不同点在于PUSCH不支持交织映射。
交织映射将资源分散到了BWP的整个频带范围内，从而获得了频率分集增益。但是，为了降低信道估计的复杂度，交织以RB bundle为单位进行，RB bundle由连续几个RB组成，也就是说PDSCH交织就是将VRB组成的RB bundle映射到PRB组成的RB bundle上。
示例性的，在一种情况下，组成RB bundle的RB个数Li由高层信令指示，则一个BWP内的RB bundle个数为：
其中，为BWP i中包括的RB数量；为BWP i相对公共资源块(common resource block，CRB)0的起始CRB索引。这样可以将RB bundle从point A开始对齐，则：
编号为0的RB bundle大小为
编号为Nbundle-1的RB bundle大小为
其余RB bundle的大小为Li。
1.1.3预编码资源块组(precoding resource block group，PRG)
一个PRG包含连续的多个PRB。终端设备假设一个PRG内所有连续的PRB采用相同的预编码，从而便于终端设备根据接收到的DMRS进行解码。PRG也可以称为物理资源块簇(PRB bundling)。
其中，PRG内包含的PRB个数为P′BWP,i，取值为2，4。
第一个PRG大小为
若最后一个PRG大小为若则最后一个PRG大小为P′BWP,i。
在子带全双工场景下，同一时刻在有的频域资源上进行接收，在有的频域资源上进行发送。上面介绍的频域资源分配并没有考虑子带全双工场景下该资源用于上行传输或下行传输。
有鉴于此，本申请实施例提供了一种数据传输方案，通过确定子带全双工场景下进行上行或下行数据传输的资源，并根据该资源进行数据传输，实现了子带全双工场景下的数据传输。
下面对本申请实施例提供的数据传输方法进行具体阐述。
如图5所示，为本申请实施例提供的一种数据传输方法的流程示意图。示例性地，该方法可以包括以下步骤：
S501、终端设备在频域资源集合中确定M个资源。
S502、网络设备在频域资源集合中确定M个资源。
S503、终端设备根据M个资源与网络设备进行数据传输。相应的，网络设备也根据M个资源与终端设备进行数据传输。即终端设备和网络设备根据M个资源进行数据传输。
本申请中的数据比如可以为传输块(transport block，TB)或码字(codeword，CW)等。
本申请实施例中，频域资源集合可以是一个或多个BWP或载波。该频域资源集合中包括至少一段频域资源，至少一段频域资源包括至少一段上行频域资源和/或至少一段下行频域资源。为了方便描述，下文中以频域资源集合是一个BWP为例对本申请提供的技术方案进行示例性说明。
其中，上行频域资源是一段连续的频域资源，例如，一段连续的资源块(resource block，RB)或者子载波，是仅用于上行传输的频域资源。示例性的，该上行频域资源可以是子带全双工中的上行子带。
下行频域资源是一段连续的频域资源，例如，一段连续的RB或者子载波，是仅用于下行传输的频域资源。示例性的，该下行频域资源可以是子带全双工中的下行子带。
子带全双工场景中的子带的划分和/或每个子带上的传输方向(上行或下行)可以为网络设备配置的，或者协议规定的，或者通过其他方式确定的，本申请不作限制。
针对终端设备而言，频域资源集合可以是网络设备配置给终端设备的，或者预先设置在终端设备中的，或者协议规定的，或者终端设备和网络设备协商确定的，本申请不作限制。
在本申请实施例中，数据传输包括：发送数据和/或接收数据。例如，在S503中，终端设备可以根据M个资源向网络设备发送PUSCH和/或从网络设备接收PDSCH。
终端设备、网络设备采用同样的方式在上述频域资源集合中确定M个资源，M个资源为M个资源块组或M个资源块(即M个RB)，M为大于0的整数。以下分为情况1(M个资源为M个资源块组)和情况2(M个资源为M个RB)对本申请提供的技术方案进行示例性说明。
情况1、M个资源为M个资源块组。
在情况1下，M个资源是指对频域资源集合进行资源块组的划分后得到的资源，一个资源块组为一个资源。M个资源中的部分或全部资源可以在后续过程中由网络设备分配给终端设备用于数据传输。
在情况1下，在一种实现方式中，资源块组可以为上文中的RBG。此时，在下文中将资源块组描述为RBG，也就是说，下文中的RBG是指资源块组为RBG。
在情况1下，在另一种实现方式中，资源块组中的RB为VRB，资源块组可以为VRB组成的RB bundle，此时，在下文中将资源块组描述为RB bundle，也就是说，下文中的RB bundle是指资源块组为VRB组成的RB bundle。
在情况1下，在再一种实现方式中，资源块组可以为PRG，此时，在下文中将资源块组描述为PRG，也就是说，下文中的PRG是指资源块组为PRG。
为了使得本申请更加的清楚，分为情况1.1(资源块组为RBG)、情况1.2(资源块组为VRB组成的RB bundle)、情况1.3(资源块组为PRG)对本申请提供的技术方案进行示例性说明。
情况1.1、资源块组为RBG
在情况1.1下，M个RBG中的每个RBG包括多个连续的RB，即多个连续的RB被划分为一个RBG。
在情况1.1下，RBG划分可以采用现有的方式，也可以采用新的划分方式，以下通过情况1.1.1(RBG划分采用现有的方式)和情况1.1.2(RBG划分采用新的划分方式)分别进行说明。
情况1.1.1、RBG划分采用现有的方式。
在情况1.1.1下，可以理解的是，由于频域资源集合既包括上行频域资源，又包括下行频域资源，因此，某些RBG中可能包含传输方向不同的RB。示例性的，参见图6，图6为本申请实施例示例的一个频域资源集合的示意图，该频域资源集合包括下行频域资源1、下行频域资源2和上行频域资源1。上述频域资源集合被划分为8个RBG：RBG0～RBG7。其中，RBG0～RBG2、RBG7中包括的RB均为用于下行传输的RB；RBG4、RBG5中包括的RB均为用于上行传输的RB；RBG3、RBG6中既包括了用于上行传输的RB，又包括了用于下行传输的RB。
在情况1.1.1下，S503在具体实现时可以包括：终端设备根据M个RBG中的可用RBG与网络设备进行数据传输。相应的，网络设备也根据M个RBG中的可用RBG与终端设备进行数据传输。也即终端设备和网络设备根据M个RBG中的可用RBG进行数据传输。例如，终端设备根据M个RBG中的可用RBG向网络设备发送数据，网络设备根据M个RBG中的可用RBG从终端设备接收数据。或者，网络设备备根据M个RBG中的可用RBG向终端设备发送数据，终端设备根据M个RBG中的可用RBG从网络设备接收数据。
在一种情况下，可用RBG是指包含的所有的RB均为可用RB的RBG。此时，数据的大小根据用于传输数据的可用RBG中的RB确定。在另一种情况下，可用RBG是指包含的所有的RB中存在可用RB的RBG。此时，数据的大小根据用于传输数据的可用RBG中的可用RB确定。用于传输数据的可用RBG可以为全部可用RBG中的部分或全部可用RBG。本文中出现的可用RB是指与传输方向相同的RB，其余RB均为不可用RB。例如，若需要进行上行传输，则可以用于上行传输的RB为可用RB，可以用于下行传输的RB为不可用RB。若需要进行下行传输，则可以用于下行传输的RB为可用RB，可以用于上行传输的RB为不可用RB。示例性的，参见图6，若需要进行上行传输，则可以用于上行传输的PRB13～PRB24为可用RB，可以用于下行传输的PRB1～PRB12以及PRB25～PRB30为不可用RB。若需要进行下行传输，则可以用于下行传输的PRB1～PRB12以及PRB25～PRB30为可用RB，可以用于上行传输的PRB13～PRB24为不可用RB。
在情况1.1.1下，编号为n的VRB是映射到编号为n的PRB的。情况1.1.1下的可用RB是指可用PRB，但是编号为n的VRB是映射到编号为n的PRB的，因此，可用RB也可以 认为是可用VRB。
在情况1.1.1下，上述方法还包括：网络设备发送配置信息(记为第一配置信息)，第一配置信息用于配置N个RBG，N个RBG属于M个RBG，N为大于0的整数。相应的，终端设备接收第一配置信息，在N个RBG中确定用于传输数据的可用RBG。可以理解的是，为了向终端设备发送数据或者接收终端设备发送的数据，网络设备也需要在N个RBG中确定用于传输数据的可用RBG。
对于N个RBG的配置，可以有以下几个示例：
在一个示例中，网络设备配置的N个RBG中不允许包含不可用RB，即N个RBG中的RB均为可用RB。仍参考图6，如需配置进行下行传输的资源，虽然RBG3、RBG6中包括可用PRB，但RBG3、RBG6中也包括不可用RB(具体地，RBG3中包括用于上行传输的PRB13～PRB15，RBG6中包括用于上行传输的PRB24)，那么网络设备不配置RBG3、RBG6用于下行传输，当然，RBG4、RBG5中包括的RB全部为不可用RB，则网络设备配置的N个RBG中不包括RBG3～RBG6。如需配置进行上行传输的资源，虽然RBG3、RBG6中包括可用PRB，但RBG3、RBG6中也包括不可用RB(具体地，RBG3中包括用于下行传输的PRB12，RBG6中包括用于下行传输的PRB25～PRB27)，那么网络设备不配置RBG3、RBG6用于上行传输，当然，RBG0～RBG2、RBG7中包括的RB全部为不可用RB，则网络设备配置的N个RBG中不包括RBG0～RBG3、RBG6～RBG7。
在该示例中，不允许N个RBG中包含不可用RB，N个RBG中的RB均为可用RB，网络配置方式简单。
在另一个示例中，网络设备配置的N个RBG中允许包含不可用RB，即N个RBG中的每个RBG均包含可用RB。仍参考图6，如需配置进行下行传输的资源，虽然RBG3、RBG6中包括不可用RB(具体地，RBG3中用于上行传输的PRB13～PRB15不可用，以及RBG6中的用于上行传输的PRB24不可用)，但是网络设备配置的N个RBG可以包括RBG3、RBG6。如需配置进行上行传输的资源，虽然RBG3、RBG6中包括不可用RB(具体地，RBG3中用于下行传输的PRB12不可用，以及RBG6中的用于下行传输的PRB25～PRB27不可用)，但是网络设备配置的N个RBG可以包括RBG3、RBG6。
在该示例中，网络设备配置的N个RBG中允许包含不可用RB，提高了资源利用率。
示例性地，第一配置信息可以是DCI中的频域资源分配字段。以子带全双工场景下的下行传输为例，该频域资源分配字段通过一个位图来指示哪些RBG是分配给PDSCH传输的：一个位图中的每个比特代表一个RBG，最高比特对应RBG0，以此类推。比特为1表示该RBG分配给PDSCH传输，比特为0表示该RBG不分配给PDSCH传输。
以子带全双工场景下的上行传输为例，该频域资源分配字段通过一个位图来指示哪些RBG是分配给PUSCH传输的：一个位图中的每个比特代表一个RBG，最高比特对应RBG0，以此类推。比特为1表示该RBG分配给PUSCH传输，比特为0表示该RBG不分配给PUSCH传输，反之亦可。
示例性的，基于图6所示的示例，假设要进行下行传输，网络设备配置的N个RBG中允许包含不可用RB，网络设备配置的RBG可以是RBG0～RBG3、以及RBG6、RBG7中的N个。具体地，假设N＝4，网络设备发送的DCI中的频域资源分配字段的值为001100，则表示RBG2和RBG6被分配给了终端设备。网络设备可以在RBG2和RBG6上向终端设备发送数据，终端设备可以在RBG2和RBG6上从网络设备接收数据。数据的大小根据RBG2和RBG6中包括的RB确定。
假设要进行下行传输，网络设备配置的N个RBG中不允许包含不可用RB，网络设备配置的RBG可以是RBG0～RBG2和RBG7中的N个。具体地，假设N＝2，若网络设备发送的DCI中的频域资源分配字段的值为0011，则表示RBG2和RBG7被分配给了终端设备，也就是说，网络设备可以在RBG2和RBG7上向终端设备发送数据，终端设备可以在RBG2和RBG7上从网络设备接收数据。数据的大小根据RBG2和RBG7中的RB确定。
基于图6所示的示例，假设要进行上行传输，网络设备配置的N个RBG中允许包含不可用RB，网络设备配置的RBG可以是RBG3～RBG6中的N个。具体地，假设N＝2，网络设备发送的DCI中的频域资源分配字段的值为0011，则表示RBG5和RBG6被分配给了终端设备。也就是说，终端设备可以在RBG5和RBG6上向网络设备发送数据，网络设备可以在RBG5和RBG6上从终端设备接收数据。数据的大小根据RBG5和RBG6中包括的可用RB确定。
假设要进行上行传输，网络设备配置的N个RBG中不允许包含不可用RB，网络设备配置的RBG可以是RBG4和RBG5中的N个。具体地，假设N＝1，网络设备发送的DCI中的频域资源分配字段的值为01，则表示RBG5被分配给了终端设备。也就是说，终端设备可以在RBG5上向网络设备发送数据，网络设备可以在RBG5上从终端设备接收数据。数据的大小根据RBG5中的RB确定。
采用情况1.1.1，在子带全双工场景下可以采用已有的方式划分RBG，实现简单，对协议改动较小。
情况1.1.2、RBG划分采用新的划分方式。
新的划分方式可以为以下方式1或方式2。
方式1、RBG以频域资源为粒度进行划分。即针对每个频域资源，例如，针对每个子带，都按上文中介绍的“1.1.1Type 0资源分配”中的公式确定频域资源内第一个RBG，最后一个RBG，及中间RBG的个数。具体地，对于一个下行频域资源，确定频域资源集合中该下行频域资源内第一个RBG，最后一个RBG以及中间RBG的个数。对于一个上行频域资源，确定频域资源集合中该上行频域资源内第一个RBG，最后一个RBG以及中间RBG的个数。
示例性的，参见图7，为本申请实施例示例的另一个频域资源集合的示意图，频域资源集合包括下行频域资源1、下行频域资源2和上行频域资源1中的RB。分别对下行频域资源1、下行频域资源2和上行频域资源1进行RBG划分，下行频域资源1和下行频域资源2包括的RBG和上行频域资源1包括的RBG分别编号，下行频域资源1和下行频域资源2包括的RBG可以联合编号，也可以分别编号。图7中以下行频域资源1和下行频域资源2上的RBG联合编号为例进行示例。对于下行频域资源1(例如，下行子带1)，下行频域资源1包括RBG0～RBG3。对于上行频域资源1(例如，上行子带1)，上行频域资源1包括RBG0'～RBG3'。对于下行频域资源2(例如，下行子带2)，下行频域资源2包括RBG4～RBG5。
方式2、RBG以传输方向相同的部分或全部频域资源作为整体为粒度进行划分。例如，针对所有相同方向的频域资源(例如，所有相同方向的子带)，可以都按上文中介绍的“1.1.1Type 0资源分配”中的公式确定所有相同方向的频域资源内第一个RBG，最后一个RBG，及中间RBG的个数。具体地，对于频域资源集合中的所有下行频域资源，确定频域资源集合中这些下行频域资源内第一个RBG，最后一个RBG以及中间RBG的个数。对于频域资源集合中的所有上行频域资源，确定频域资源集合中这些上行频域资源内第一个RBG，最后一个RBG以及中间RBG的个数。如图8所示，为本申请实施例提供的又一个频域资源集合的示意图，两个下行频域资源的组合统一进行RBG划分，当两个下行频域资源之间存在上行频域资源时，可能会出现RBG内的RB非连续。例如，图8中，下行频域资源中被划分出的RBG3 包括PRB12、PRB25～PRB27，可见，RBG3内的RB是非连续的。
示例性的，参见图8，频域资源集合包括下行频域资源1、下行频域资源2和上行频域资源1中的RB，将下行频域资源1和下行频域资源2作为一个整体进行RBG的划分，划分出的用于下行传输的RBG0～RBG4均为下行可用的RBG；以及将上行频域资源1作为一个整体进行RGB的划分，划分出的用于上行传输的RBG0'～RBG3'均为上行可用的RBG。
上述2种方式，由于按照新的方式划分RBG，针对一个传输方向，RBG的数量减少，相应的，用于指示RBG的比特减少，因此，均需要在DCI内的频域资源分配字段的高位填充0，使DCI内的频域资源分配字段的长度不变。
在情况1.1.2中，S503在具体实现时可以包括：终端设备根据M个RBG中的可用RBG与网络设备进行数据传输。相应的，网络设备也根据M个RBG中的可用RBG与终端设备进行数据传输。
在情况1.1.2中，可以理解的是，RBG中不会包含传输方向不同的RB，即一个RBG中的RB的传输方向均相同。因此，可用RBG是指包含的所有的RB均为可用RB的RBG。数据的大小根据用于传输数据的可用RBG中的RB确定。
在情况1.1.2下，上述方法还包括：网络设备发送配置信息(记为第二配置信息)，第二配置信息用于配置N个RBG，N个RBG属于M个RBG，N为大于0的整数。相应的，终端设备接收第二配置信息，在N个RBG中确定可用RBG。可以理解的是，为了向终端设备发送数据或者接收终端设备发送的数据，网络设备也需要在N个RBG中确定可用RBG。另外，可以理解的是，若N个RBG中包括的RBG均为可用RBG，则终端设备无需在N个RBG中确定可用RBG，在接收到配置信息之后，直接根据N个RBG进行数据传输即可。
示例性地，第二配置信息可以是DCI中的频域资源分配字段。
以子带全双工场景下的下行传输为例，该频域资源分配字段通过一个位图来指示哪些RBG是分配给PDSCH传输的：一个位图中的每个比特代表一个RBG，最高比特对应RBG0，以此类推。比特为1表示该RBG分配给PDSCH传输，比特为0表示该RBG不分配给PDSCH传输。
以子带全双工场景下的上行传输为例，该频域资源分配字段通过一个位图来指示哪些RBG是分配给PUSCH传输的：一个位图中的每个比特代表一个RBG，最高比特对应RBG0，以此类推。比特为1表示该RBG分配给PUSCH传输，比特为0表示该RBG不分配给PUSCH传输，反之亦可。示例性的，基于图7所示的示例，假设要进行下行传输，网络设备发送的DCI中的频域资源分配字段包括6个比特，6个比特从前至后分别对应RBG0、RBG1、RBG2、RBG3、RBG4和RBG5。若6个比特的值为001101，则表示RBG2、RBG3和RBG5被分配给了终端设备，即N个RBG为RBG2、RBG3和RBG5，N个RBG中的可用为RBG2、RBG3和RBG5，也就是说，网络设备可以在RBG2、RBG3和RBG5上向终端设备发送数据，终端设备可以在RBG2、RBG3和RBG5上从网络设备接收数据。数据的大小根据RBG2、RBG3和RBG5中包括的RB确定。
示例性的，基于图8所示的示例，假设要进行下行传输，网络设备发送的DCI中的频域资源分配字段包括4个比特，4个比特从前至后分别对应RBG0'、RBG1'、RBG2'和RBG3'。若4个比特的值为0011，则表示RBG2'和RBG3'被分配给了终端设备，即N个RBG为RBG2'和RBG3'，N个RBG中的可用为RBG2'和RBG3'，也就是说，终端设备可以在RBG2'和RBG3'上向网络设备发送数据，网络设备可以在RBG2'和RBG3'上从终端设备接收数据。数据的大小根据RBG2'和RBG3'中的RB确定。
采用情况1.1.2所示的方式，可以充分的调度资源，不会存在不能被调度的RB，提高了资源的利用率。
情况1.2、资源块组为RB bundle
在情况1.2下，RB bundle划分可以采用现有的方式，也可以采用新的划分方式，以下通过情况1.2.1(RB bundle划分采用现有的方式)和情况1.2.2(RB bundle划分采用新的划分方式)分别进行说明。
情况1.2.1、RB bundle划分采用现有的方式。
在情况1.2.1下，可以理解的是，由于频域资源集合既包括上行频域资源，又包括下行频域资源，因此，某些RB bundle中可能包含传输方向不同的RB。示例性的，参见图9，图9为本申请实施例示例的又一个频域资源集合的示意图，该频域资源集合包括下行频域资源1、下行频域资源2和上行频域资源1。上述频域资源集合被划分为8个PRB bundle：PRB bundle0～PRB bundle7。其中，PRB bundle0～PRB bundle2、PRB bundle7中包括的RB均为用于下行传输的RB；PRB bundle4、PRB bundle5中包括的RB均为用于上行传输的RB；PRB bundle3、PRB bundle6中既包括了用于上行传输的RB，又包括了用于下行传输的RB。由于PRB和VRB存在映射关系，因此，用于下行传输的PRB对应的VRB也可以认为是用于下行传输的，用于上行传输的PRB对应的VRB也可以认为是用于上行传输的。
在情况1.2.1下，S503在具体实现时可以包括：终端设备和网络设备根据M个RB bundle中的可用RB bundle进行数据传输。例如，终端设备根据M个RB bundle中的可用RB bundle向网络设备发送数据，网络设备根据M个RB bundle中的可用RB bundle从终端设备接收数据。或者，网络设备备根据M个RB bundle中的可用RB bundle向终端设备发送数据，终端设备根据M个RB bundle中的可用RB bundle从网络设备接收数据。
在一种情况下，可用RB bundle是指包含的所有的RB均为可用RB的RB bundle。在另一种情况下，可用RB bundle是指包含的所有的RB中存在可用RB的RB bundle。用于传输数据的可用RB bundle可以为全部可用RB bundle中的部分或全部可用RB bundle。本文中出现的可用RB是指与传输方向相同的RB，其余RB均为不可用RB。例如，若需要进行上行传输，则可以用于上行传输的RB为可用RB，可以用于下行传输的RB为不可用RB。由于PRB和VRB存在映射关系，因此，可用PRB对应的VRB也可以认为是可用的，不可用PRB对应的VRB也可以认为是不可用的。
示例性的，参见图9，若需要进行上行传输，则可以用于上行传输的PRB13～PRB24为可用RB，可以用于下行传输的PRB1～PRB12以及PRB25～PRB30为不可用RB。若需要进行下行传输，则可以用于下行传输的PRB1～PRB12以及PRB25～PRB30为可用RB，可以用于上行传输的PRB13～PRB24为不可用RB。在这里，编号为n的VRB是映射到编号为f(n)的PRB的。
采用情况1.2.1所示的方式，在子带全双工场景下可以采用已有的方式划分RB bundle，实现简单，协议改动较小。
情况1.2.2、RB bundle划分采用新的划分方式。
新的划分方式可以为以下方式3或方式4。
方式3、RB bundle以频域资源为粒度进行划分。即在频域资源集合内，RB bundle的划分是按照频域资源进行的。即针对每个频域资源，都按上文中介绍的“1.1.2.1交织资源块簇”中的公式确定频域资源内第一个RB bundle，最后一个RB bundle，及中间RB bundle的个数。具体地，对于一个下行频域资源，确定频域资源集合中该下行频域资源内第一个RB bundle， 最后一个RB bundle以及中间RB bundle的个数。对于一个上行频域资源，确定频域资源集合中该上行频域资源内第一个RB bundle，最后一个RB bundle以及中间RB bundle的个数。
示例性的，参见图10，为本申请实施例示例的又一个频域资源集合的示意图，频域资源集合包括下行频域资源1、下行频域资源2和上行频域资源1中的RB。分别对下行频域资源1、下行频域资源2和上行频域资源1进行RB bundle划分，下行频域资源1包括的RB bundle和下行频域资源2包括的RB bundle可以联合编号，也可以分别编号，下行频域资源1、下行频域资源2包括的RB bundle和上行频域资源1包括的RB bundle分开编号。示例性的，下行频域资源1包括RB bundle0～RB bundle3。上行频域资源1包括RB bundle0'～RB bundle3'。下行频域资源2包括RB bundle4～RB bundle5。
方式4、RB bundle以传输方向相同的部分或全部频域资源作为整体为粒度进行划分。即在频域资源集合内，RB bundle的划分是按照传输方向进行的。例如，针对所有传输相同方向的频域资源，都按上文中介绍的“1.1.2.1交织资源块簇”中的公式确定第一个RB bundle，最后一个RB bundle，及中间RB bundle的个数。具体地，对于频域资源集合中的所有下行频域资源，确定第一个RB bundle，最后一个RB bundle以及中间RB bundle的个数。对于频域资源集合中的所有上行频域资源确定第一个RB bundle，最后一个RB bundle以及中间RB bundle的个数。如图11所示，为本申请实施例提供的又一个频域资源集合的示意图，两个下行频域资源作为整体统一进行RB bundle划分，当中间有上行频域资源时，可能会出现RB bundle内的RB非连续。例如，图11中，下行频域资源中被划分出的RB bundle3包括PRB12、PRB25～PRB27，可见，RB bundle3内的RB是非连续的。
示例性的，参见图11，频域资源集合包括下行频域资源1、下行频域资源2和上行频域资源1中的RB，将下行频域资源1和下行频域资源2作为一个整体进行RB bundle的划分，划分出的用于下行传输的RB bundle0～RB bundle4均为下行可用的RB bundle；以及将上行频域资源1作为一个整体进行RB bundle的划分，划分出的用于上行传输的RB bundle0'～RB bundle3'均为上行可用的RB bundle。
在情况1.2.2中，S503在具体实现时可以包括：终端设备和网络设备根据M个RB bundle中的可用RB bundle进行数据传输。
在情况1.2.2中，可以理解的是，针对PRB，RB bundle中不会包含传输方向不同的RB，即一个RB bundle中的RB的传输方向均相同。因此，针对PRB，可用RB bundle是指包含的所有的RB均为可用RB的RB bundle。针对VRB，RB bundle中会包含传输方向不同的RB，因此，针对VRB，可用RB bundle是指包含的所有的RB均为可用RB的RB bundle或者可用RB bundle是指包含的所有的RB中存在可用RB的RB bunble。需要说明的是，本申请若无特别说明，可用RB bunble可以是可用PRB bunble，也可以是可用VRB bunble。
采用情况1.2.2，可以充分的调度资源，不会存在不能被调度的RB，提高了资源的利用率。
在情况1.2下，上述方法还包括：网络设备发送配置信息(记为第三配置信息)，第三配置信息用于配置多个连续的VRB。相应的，终端设备接收第三配置信息。该多个连续的VRB包括M个VRB bundle中的可用VRB bundle中的部分或全部可用VRB。该情况下，上述步骤“终端设备和网络设备根据M个RB bundle中的可用RB bundle进行数据传输”在具体实现时可以包括：终端设备和网络设备在该多个连续的VRB中的可用VRB映射的PRB上进行数据传输。具体的，第三配置信息可以为RIV。
在情况1.2下，网络设备和终端设备确定VRB bundle后，将VRB bundle与PRB bundle 进行映射。之后，网络设备向终端设备发送第三配置信息，终端设备根据第三配置信息确定可用VRB，在可用VRB映射到的PRB上进行数据传输。
在情况1.2下，示例性的，基于图9、图10或图11所示的示例，假设要进行下行传输，网络设备发送的RIV指示的起始RB为RB16，连续的RB的个数为4，则终端设备在VRB16-VRB19映射到的PRB8-PRB11上发送数据，网络设备可以在VRB16-VRB19映射到的PRB8-PRB11上接收数据。数据的大小可以根据PRB8-PRB11确定。假设要进行上行传输，网络设备发送的RIV指示的起始RB为RB12，连续的RB的个数为4，则终端设备可以在VRB12-VRB15映射到的PRB20-PRB23上发送数据，网络设备可以在VRB12-VRB15映射到的PRB20-PRB23上接收数据。数据的大小可以根据PRB20-PRB23确定。
在情况1.2下，示例性的，基于图9、图10或图11所示的示例，假设要进行下行传输，网络设备发送的RIV指示的起始RB为RB16，连续的RB的个数为12，则终端设备在VRB16-VRB19以及VRB21-VRB24映射到的PRB8-PRB11、PRB12以及PRB25-PRB27上发送数据，网络设备可以在PRB8-PRB11、PRB12以及PRB25-PRB27上接收数据。数据的大小可以根据PRB8-PRB11、PRB12以及PRB25-PRB27确定。假设要进行上行传输，网络设备发送的RIV指示的起始RB为RB20，连续的RB的个数为8，则终端设备可以在VRB25-VRB27以及VRB20映射到的PRB13-PRB15以及PRB24上发送数据，网络设备可以在PRB13-PRB15以及PRB24上接收数据。数据的大小可以根据PRB13-PRB15以及PRB24确定。
情况1.3、资源块组为PRG
在情况1.3下，基于上述频域资源集合划分PRG，属于同一个PRG的RB可以采用相同的预编码。
在情况1.3下，PRG划分可以采用现有的方式，也可以采用新的划分方式，以下通过情况1.3.1(PRG划分采用现有的方式)和情况1.3.2(PRG划分采用新的划分方式)分别进行说明。
情况1.3.1、PRG划分采用现有的方式。
在情况1.3.1下，可以理解的是，由于频域资源集合既包括上行频域资源，又包括下行频域资源，因此，某些PRG中可能包含传输方向不同的RB。示例性的，参见图12，图12为本申请实施例示例的又一个频域资源集合的示意图，该频域资源集合包括下行频域资源1、下行频域资源2和上行频域资源1。上述频域资源集合被划分为8个PRG：PRG0～PRG7。其中，PRG0～PRG2、PRG7中包括的RB均为用于下行传输的RB；PRG4、PRG5中包括的RB均为用于上行传输的RB；PRG3、PRG6中既包括了用于上行传输的RB，又包括了用于下行传输的RB。
在情况1.3.1下，
采用情况1.3.1，在子带全双工场景下采用已有的方式划分PRG，实现简单，改动较小。
情况1.3.2、PRG划分采用新的划分方式。
新的划分方式可以为以下方式5或方式6。
方式5、PRG以频域资源为粒度进行划分。即在频域资源集合内，PRG的划分是按照频域资源进行的。即针对每个频域资源，按根据上文中介绍的“1.1.3预编码资源块组”中的公式确定频域资源内第一个PRG，最后一个PRG，及中间PRG的个数。具体地，对于一个下行频域资源，确定频域资源集合中该下行频域资源内第一个PRG，最后一个PRG以及中间PRG的个数。对于一个上行频域资源，确定频域资源集合中该上行频域资源内第一个PRG，最后一个PRG以及中间PRG的个数。
示例性的，参见图13，为本申请实施例示例的又一个频域资源集合的示意图，频域资源集合包括下行频域资源1、下行频域资源2和上行频域资源1中的RB。分别对下行频域资源1、下行频域资源2和上行频域资源1进行PRG划分，下行频域资源1包括的PRG和下行频域资源2包括的PRG可以联合编号，也可以分别编号，下行频域资源1、下行频域资源2包括的PRG和上行频域资源1包括的PRG分开编号。示例性的，参见图13，下行频域资源1(例如，下行子带1)，包括PRG0～PRG3。上行频域资源1(例如，上行子带1)包括PRG0'～PRG3'。下行频域资源2包括PRG4～PRG5。
方式6、PRG以传输方向相同的部分或全部频域资源作为整体为粒度进行划分。例如，在频域资源集合内，PRG的划分是按照传输方向进行的。即针对所有相同传输方向的频域资源，根据上文中介绍的“1.1.3预编码资源块组”中的公式第一个PRG，最后一个PRG，及中间PRG的个数。具体地，对于频域资源集合中的所有下行频域资源，确定频域资源集合中这些下行频域资源内第一个PRG，最后一个PRG以及中间PRG的个数。对于频域资源集合中的所有上行频域资源，确定频域资源集合中这些上行频域资源内第一个PRG，最后一个PRG以及中间PRG的个数。如图14所示，为本申请实施例提供的又一个频域资源集合的示意图，两个下行频域资源作为整体统一进行PRG划分，当两个下行频域资源之间有上行频域资源时，可能会出现PRG内的RB非连续。例如，图14中，频域资源集合包括下行频域资源1、下行频域资源2和上行频域资源1中的RB，将下行频域资源1和下行频域资源2作为一个整体进行PRG的划分，得到PRG0～PRG5；将上行频域资源1作为一个整体进行PRG的划分，得到PRG0'～PRG3'。其中，下行频域资源中被划分出的PRG3包括PRB12、PRB25～PRB27，可见，PRG3内的RB是非连续的。
采用情况1.3，可以简化终端设备决定预编码粒度的过程，如不会存在包含传输方向不同的RB的PRG。
在情况1.3下，针对下行传输，网络设备划分PRG后，对于一个PRG中所有连续的PRB采用相同的预编码。终端设备采用同样的方式划分PRG，接收网络设备配置的传输资源(例如，上文中的N个RBG，或者，RIV指示的连续的VRB)并确定用于传输数据的PRB。网络设备可以判断用于传输数据的PRB中哪些PRB属于同一个PRG，属于同一个PRG的PRB发送数据时采用相同的预编码。终端设备可以判断哪些PRB属于同一个PRG，属于同一个PRG的PRB统一进行解调。
在情况1.3下，针对上行传输，网络设备划分PRG后，对于一个PRG中所有连续的PRB采用相同的预编码。终端设备采用同样的方式划分PRG，在接收到网络设备配置的传输资源(例如，上文中的N个RBG，或者，RIV指示的连续的VRB)并确定用于传输数据的PRB后，可以判断哪些PRB属于同一个PRG，属于同一个PRG的PRB采用相同的预编码。相应的，网络设备可以判断用于传输数据的PRB中哪些PRB属于同一个PRG，属于同一个PRG的PRB统一进行解调。
情况2、M个资源为M个RB(或者说M个VRB)
在情况2下，上述方法还包括：接收指示信息，指示信息用于指示M个RB中的起始RB和RB个数，起始RB和RB个数以传输方向相同的部分或全部频域资源(该频域资源可以是由VRB组成的频域资源)作为整体确定的。此时，S503在具体实现时可以包括：终端设备和网络设备在M个RB上进行数据传输。
其中，指示信息可以为RIV。终端设备通过RIV计算数据的起始RB和RB个数。
已有的方法中，当存在多个相同方向的子带时，是无法支持PDSCH或PUSCH的资源跨 多个子带的方式的。该方法在具体实现时，在频域资源集合中，可以先将与传输方向不同的RB排除，并采用剩余的RB计算RIV。即上文中介绍的“1.1.2Type 1资源分配”中的数值不再是BWP内包含的RB个数，而是指传输方向相同的频域资源中的RB个数。根据上述方式得到RIV后，由于用于计算RIV的RB数量可能减少，因此，在DCI内的频域资源分配字段的高位填0，从而使得DCI内的频域资源分配字段的长度不变。
例如，参见图15，为本申请实施例示例的又一个频域资源集合的示意图，假设要进行下行传输、且VRB和PRB的映射方式为非交织映射，假设根据RIV确定的起始RB为RB8，RB个数为6，则用于传输PDSCH的PRB可参见图15所示的PRB8～PRB12以及PRB25。即网络设备在计算RIV时，先将与下行传输方向不同的PRB13～PRB24排除，然后再采用剩余的RB计算RIV。假设要进行上行传输、且VRB和PRB的映射方式为非交织映射，根据RIV确定的起始RB为RB15，RB个数为6，则用于传输PUSCH的PRB可参见图15所示的PRB15～PRB20。
采用情况2，RIV所指示的RB可以均为可用RB，可以在这些RB上进行数据传输，实现了子带全双工下的数据传输。
上述图6～图15所示的频域资源集合的示意图中，各资源块组包括的资源块的大小仅为示例，其也可以是其它的资源块的大小。例如，图6中，RB bundle0包括3个RB，实际上RB bundle0可以包括任意正整数个RB。又例如，图9中，RB bundle0包括3个VRB，实际上RB bundle0可以包括任意正整数个VRB。又例如，图12中，PRG0包括3个RB，实际上PRG0可以包括任意正整数个RB。
另外，图9～图11中VRB bundle与PRB bundle的映射关系也仅为示例，还可以是其它的映射关系。
上述情况1.1可以应用于子带全双工场景下的Type 0资源分配场景。
上述情况1.2和情况1.4可以应用于子带全双工场景下的Type 1资源分配场景。示例性的，具体可以应用于Type 1资源分配场景下的交织映射场景和非交织映射场景。
上述情况1.3可以应用于子带全双工场景下的PRG划分场景。
本申请实施例中的RB也可以替换为子载波。
根据本申请实施例提供的一种数据传输方法，通过确定子带全双工场景下进行上行或下行数据传输的资源，并根据该资源进行数据传输，实现了子带全双工场景下的数据传输。
需要说明的是，本申请虽然主要解决子带全双工场景下的数据传输问题，但是也可以应用于非子带双工场景下具有类似需求的场景中，本申请不作限制。
可以理解的是，以上各个实施例中，由终端设备实现的方法和/或步骤，也可以由可用于终端设备的部件(例如芯片或者电路)实现；由网络设备实现的方法和/或步骤，也可以由可用于网络设备的部件(例如芯片或者电路)实现。

本申请实施例可以根据上述方法实施例中对数据传输装置进行功能模块的划分，例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个处理模块中。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。需要说明的是，本申请实施例中对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。
基于上述数据传输方法的同一构思，本申请还提供了如下数据传输装置：
如图16所示，为本申请实施例提供的一种数据传输装置的结构示意图，该数据传输装置1600包括：处理单元161和收发单元162。
