Description

一种数据传输方法、终端以及基站
本申请要求在2017年5月5日提交中国专利局、申请号为201710314107.7、发明名称为“一种数据传输方法、终端以及基站”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
本申请涉及无线通信技术领域，尤其涉及一种数据传输方法、终端以及基站。
背景技术
随着移动通信业务需求的发展变化，国际电信联盟(International Telecommunication Union，ITU)和第三代产业合作计划(3rd Generation Partnership Project，3GPP)等组织都开始研究新的无线通信系统例如5G-NR(New Radio，NR)系统。在LTE系统中，终端与基站的数据传输是以传输块(TB，Transport Block)为单位进行的，即终端和基站都是基于TB进行数据传输的。以下行传输为例，例如终端接收TB后，仅针对TB进行ACK/NACK反馈，可以反馈肯定确认(ACKnowledgement，ACK)，或者反馈否定确认(Non-ACKnowledgement，NACK)，以告知基站终端接收的TB是否正确。通常一个TB包含至少一个CB，即只有一个TB中的所有CB都正确接收，该TB才算正确接收，终端会反馈ACK，只要该TB中有一个CB错误接收，该TB的反馈信息就为NACK。那么，基站接收到反馈信息为NACK之后，便重传该TB。可见，LTE系统中以TB为单位进行数据传输时，容易出现不必要的重传冗余，进而使得传输效率较低。而5G系统中支持更多的业务，如果仍然使用LTE系统的基于TB的数据传输方式将会影响业务的传输，所以LTE中的基于TB的数据传输方式不再适用于5G-NR系统或者其它新的无线通信系统中。

具体实施方式
本申请提供一种数据传输方法、终端以及基站，用以提供一种新的数据传输方式。
为了解决上述技术问题，本申请总体思路如下：
在本申请实施例提供的技术方案中，终端获取下行共享信道中的每个CBG对应的第一指示域；所述第一指示域包含第一指示信息，所述第一指示信息用于指示所述每个CBG的编号；所述终端根据所述第一指示信息识别所述每个CBG。即基站与终端之间以CBG为单位进行数据重传和ACK/NACK反馈，一个CBG通常包含至少一个CB，所以一个TB可以分割为至少一个CBG。并且，由于ACK/NACK传输本身的错误概率，可能导致终端对一个CBG传输的反馈信息为NACK，而基站理解为ACK，或者反之，从而导致终端和基站对重传的CBG的理解不一致，导致错误的混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)合并，本申请中每个CBG都具有编号，使得基站和终端对于每个重传的CBG的理解一致。
为了更好的了解上述技术方案，下面通过附图以及具体实施例对本申请技术方案进行详细的说明，应当理解本申请实施例以及实施例中的具体特征是对本申请技术方案的详细的说明，而不是对本申请技术方案的限定，在不冲突的情况下，本申请实施例以及实施例中的技术特征可以相互组合。
本申请实施例第一方面提供了一种数据传输方法，请同时参考图1和图2所示，图1为本申请实施例提供的终端侧的数据传输方法的流程图。终端侧的数据传输方法可以应用于例如LTE系统、NR系统等无线通信系统中的终端中，所述终端包括但不限于手机，平板电脑等。对应于图1的终端侧的数据传输方法，本申请还提供基站侧的数据传输方法。图2为本申请实施例提供的基站侧的数据传输方法的流程图。基站侧的数据传输方法的配置方法可以应用于例如长期演进(Long Term Evolution，LTE)系统、NR(New Radio，NR)系统等无线通信系统中的基站中，所述基站可以是宏基站、家庭基站等，还可以是其 它基站。如图1所示，终端侧的随机接入资源的配置方法包括：
步骤101：终端获取下行共享信道中至少一个CBG以及与所述至少一个CBG中每个CBG对应的第一指示域；所述第一指示域包含第一指示信息，所述第一指示信息用于指示所述每个CBG的编号；
步骤102：所述终端根据所述第一指示信息识别所述每个CBG。
如图2所示，基站侧的数据传输方法包括：
步骤201：基站产生至少一个CBG以及所述至少一个CBG中每个CBG对应的第一指示域；所述第一指示域包含第一指示信息，所述第一指示信息用于指示所述每个CBG的编号；
步骤202：基站在下行共享信道中发送所述至少一个CBG以及所述第一指示域。
在介绍步骤101之前，首先介绍LTE系统中终端与网络设备之间通信的方式，请参考图2所示，为本申请实施例提供的LTE系统中网络设备与终端之间通信的示意图。图2以网络设备是基站为例。如图所示，终端通过物理下行共享信道(Physical Downlink Shared Channel，PDSCH)接收网络设备发送的下行数据，通过物理上行共享信道(Physical Uplink Shared Channel，PUSCH)向基站发送上行数据，通过物理上行控制信道(Physical Uplink Control Channel，PUCCH)向基站发送接收到的下行数据的ACK/NACK反馈信息。在LTE系统中，终端与基站之间每次传输以传输块(Transport Block，TB)为单位，一个PDSCH或PUSCH信道可以支持1或2个TB来进行数据传输。由于编码器的处理程度的限制，一个TB需要分割为K个码块(Code Block，CB)，如果对于每个CB都进行一对一的ACK/NACK反馈和重传，那么ACK/NACK反馈比特数较大。
在本申请实施例中，基站产生至少一个CBG以及所述至少一个CBG中每个CBG对应的第一指示域，对应的，终端获取下行共享信道中至少一个CBG以及与所述至少一个CBG中每个CBG对应的第一指示域。也就是说，终端与基站之间每次重传输和ACK/NACK反馈都以CBG为单位，一个TB在初始传输时被分割为多个CBG，每一个CBG中包含至少一个CB，每个CBG都会对应ACK/NACK，则如果其中某些CBG的反馈为NACK，只需要在重传的时候重新传输该TB在初始传输时被分割为的多个CBG中传输错误的CBG，避免了整个TB的重传，即避免了本省正确的CBG的冗余重输，提高了传输效率。
可选的，在步骤101之前，所述方法还包括：
终端按照下述方式中的至少一种判断所述下行共享信道中的每个CBG是否存在对应的所述第一指示域或所述第一指示域是否有效。
这里需要说明的是，有效可以理解为终端需要读取某部分内容，并根据这部分内容的具体指示内容进行相应的操作，无效可以理解为虽然这部分内容的比特数存在(处于预留状态，即reserved)，但不要求终端进行读取操作，因此终端可以不知道这部分内容所指示 的是什么，所以终端也不会按照这部分内容所指示的进行相应的操作。当然，关于有效或者无效的定义，本领域技术人员可以根据实际情况而定，本申请不作具体的限定。
方式1：所述终端接收高层信令，所述高层信令配置所述终端是否支持基于CBG的传输，当确定支持时，确定存在所述第一指示域或所述第一指示域有效，否则，确定不存在所述第一指示域或所述第一指示域无效。
方式2：用于调度所述下行共享信道的下行控制信道中存在至少1比特第三指示域，所述第三指示域用于指示CBG是否存在对应的所述第一指示域或所述第一指示域是否有效。例如“1”表示包含，“0”表示不包含，或者反之。
方式3：所述下行共享信道中还包括第四指示域，所述第四指示域用于指示CBG是否存在对应的所述第一指示域或所述第一指示域是否有效。
可选的，每个CBG都可以对应一个第四指示域，即第四指示域可以独立指示每个CBG中是否包含第一指示域或第一指示域是否有效。例如一个CBG对应1比特第四指示域信息，为“0”时表示该CBG不包含第一指示域或第一指示域无效，为“1”时表示该CBG包含第一指示域或第一指示域有效。第四指示域也可以对应所有的CBG，即下行共享信道中仅包含一个第四指示域，该第四指示域对所有CBG有效，例如1比特信息，为“0”时表示所有CBG都不包含第一指示域或第一指示域无效，为“1”时表示所有CBG都包含第一指示域或第一指示域有效。
方式4：当判断所述下行共享信道为重传时，确定CBG存在所述第一指示域或所述第一指示域有效，否则，确定CBG不存在所述第一指示域或所述第一指示域无效。
具体的，可以通过用于调度所述下行共享信道的下行控制信道中的指示域判断所述下行共享信道是否为重传，例如，所述下行控制信道中所指示的HARQ进程号与前面已经接收到的一个数据包所对应的进程号相同，且所述下行控制信道中指示为重传(例如根据NDI判断为重传)；还可以根据用于调度所述下行共享信道的下行控制信道所使用的DCI格式的不同(例如比特数不同，或DCI中存在指示域指示为哪种格式)和/或所使用的RNTI不同来判断是否重传，例如使用DCI格式1为调度初传，使用DCI格式2为调度重传，DCI格式1和格式2的DCI大小不同，或者，使用RNTI1为调度初传，使用RNTI2为调度重传等，当然也可以是两者的组合。
所述终端首先根据所述方式1～4判断所述第一指示域中是否包存在或是否有效，当判断存在或有效时，进一步解析/读取第一指示域，否则，如果判断不存在，则在共享信道中仅解析CBG数据即可，如果判断无效，则在共享信道中还是认为存在第一指示域，且需要在第一指示域占用的资源以外接收CBG数据，但不要求终端进一步解析/读取第一指示域的内容。
可选的，所述第一指示域也可以预定为总是存在或总是有效，则所述终端不需要执行 上述方式去确定所述第一指示域是否存在或是否有效，而总是按照所述第一指示域中总是存在或总是有效进行处理。
以上描述的是终端执行步骤101之前的步骤，对应的，下面介绍基站执行步骤201之前的步骤，即在步骤201之前，所述方法还包括：基站按照下述方式中的至少一种判断所述下行共享信道中的每个CBG是否存在对应的所述第一指示域或所述第一指示域是否有效。
方法1：所述基站确定终端是否支持基于CBG的传输，并通过高层信令通知给终端，当确定支持时，确定存在第一指示域或第一指示域有效，否则，确定不存在第一指示域或第一指示域无效。
方法2：用于调度所述下行共享信道的下行控制信道中存在至少1比特第三指示域，所述第三指示域用于指示CBG是否存在对应的所述第一指示域或所述第一指示域是否有效；所述基站确定是否存在所述第一指示域息或所述第一指示域是否有效，并通过所述第三指示域通知给终端。
方法3：所述下行共享信道中的还包括第四指示域，所述第四指示域用于指示CBG是否存在对应的所述第一指示域或所述第一指示域是否有效；所述基站确定是否存在所述第一指示域息或所述第一指示域是否有效，并通过所述第四指示域通知给终端。
方式4：当判断所述下行共享信道为重传时，确定CBG存在所述第一指示域或所述第一指示域有效，否则，确定CBG不存在所述第一指示域或所述第一指示域无效。
关于基站判断所述下行共享信道中的每个CBG是否存在对应的所述第一指示域或所述第一指示域是否有效的方式，请参考前述终端判断所述下行共享信道中的每个CBG是否存在对应的所述第一指示域或所述第一指示域是否有效的方式的描述，为了说明书的简洁，在此不作赘述。
可选的，所述第四指示域与所述第一指示域独立编码。
可选的，所述第一指示域与所述第一指示域对应的CBG中的CB独立编码。
可选的，上述编码方式可以为使用重复编码，单一编码(simplex encoding)，瑞德-穆勒(RM，Reed-Muller)编码等。
可选的，所述每个CBG对应的第一指示域在所述CBG对应的预定义的资源中通过打孔或者速率匹配的方式传输。
以下行数据为例，第一指示域可以在该CBG中包含的至少一个CB中的一个预定的CB所对应的资源上传输，例如，在该CBG中的第一个CB或最后一个CB所对应的预定的资源中传输，请参考图3所示，第一指示域在CBG中的第一个CB即CB 1,1所对应的资源上传输，当然也可以在最后一个CB即CB N1,1在所对应的资源上传输。当确定了在哪一个CB所对应的资源上传输时，在该CB对应的资源上通过对该CB的数据进行打孔 (puncture)传输，即该CB数据传输时不考虑第一指示域的大小，在实际映射时，如果第一指示域映射到该CB的数据所对应的资源上时，则对这部分资源上的该CB数据进行打孔，即覆盖这部分CB数据。或者通过速率匹配进行传输，即在进行CB的编码和速率匹配时，考虑CB对应的资源上同时存在第一指示域和CB数据，所以对两者分别进行编码，并考虑两者的编码后信息进行速率匹配，即CB数据和第一指示域分别占用该CB对应的资源中的不同部分进行传输，CB数据不会被第一指示域打孔或覆盖。
步骤101中，第一指示信息的比特数基于所述下行共享信道中的CBG的个数确定。例如第一指示信息的比特数可以为[log 2M]比特，其中，M可以是一个TB被分割的CBG的个数，M也可以是固定值，也可以随着TBS改变。当M为固定值时，为预先约定或者配置，当M随着TBS改变时，可以是预先定义M和TBS的对应关系，当确定了TBS之后，就可以确定相应的M值，从而确定第一指示信息的比特数。
步骤102：终端根据第一指示信息识别每个CBG。
举例来说，一个TB在初始传输时经过码块分割得到A个CB，按照特定规则将A个CB分割为5个CBG，则终端在一个TB的初始传输中接收5个CBG，CBG1、CBG2、CBG3、CBG4和CBG5。然后，终端对每个CBG产生反馈信息，例如分别为ACK，NACK，ACK，NACK，ACK，并将反馈信息发送给基站，那么基站确定CBG2、和CBG4需要重传后，则在下一次对应同一个HARQ进程号的传输中仅重传CBG2和CBG4以提高传输效率，终端在接收到对应同一个HARQ进程号的重传时，并不知道重新接收的两个CBG是该TB的初始传输中被分割为的5个CBG中的哪一个，所以终端可以根据第一指示信息识别每个CBG。
一种可能的实现方式为，假设第一指示信息的比特数为3，那么可以用000、001、010、011、100分别表示5个CBG，即第一指示信息为“001”的CBG为CBG1，第一指示信息为“010”的CBG为CBG2，第一指示信息为“011”的CBG为CBG3，第一指示信息为“011”的CBG为CBG4，第一指示信息为“100”的CBG为CBG4。那么如果终端接收两个CBG的第一指示域，第一个CBG对应的第一指示域中的第一指示信息为“001”，则确定该CBG为该TB的初始传输中被分割为的5个CBG中的CBG2。第二个CBG对应第一指示域中的第一指示信息为“011”，则确定该CBG为该TB的初始传输中被分割为的5个CBG中的CBG4。通过这种方式，终端便知道接收每个CBG与前一次接收的CBG之间的联系，从而进行对应的HARQ合并，即将多次接收到的对应同一个CBG的数据进行合并，以提高解调性能。
可选的，所述第一指示域中还包含第二指示信息，所述第二指示信息用于指示所述第一指示信息所指示的CBG编号对应的CBG的前一次或前多次传输是否遭到破坏，和/或所述第二指示信息用于指示所述第一指信息所指示的CBG编号对应的CBG的前一次或前多 次传输中哪些CB遭到破坏，其中，所述CBG包含至少一个CB，和/或所述第二指示信息用于指示所述第一指信息所指示的CBG编号对应的CBG的前一次或前多次传输的哪些符号遭到破坏。请参考图4所示，为本申请实施例提供的一种第一指示域的示意图，图4只是以第一指示域(CBG field)包含第一指示信息(CBG index)和第二指示信息(PI)为例。
以下将通过举例说明数据遭到破坏的一种可能的情况，例如对于5G NR系统支持更多业务类型，例如支持低时延高可靠通信(URLLC，Ultra-Reliable and Low Latency Communication)业务和增强移动宽带(eMBB，enhanced Mobile Broadband)业务。URLLC可以在分配给eMBB的传输资源上传输，即对eMBB业务的传输资源进行抢占(pre-emption)此时URLLC业务在与eMBB重叠传输的部分会覆盖eMBB业务，即eMBB业务在与URLLC重叠传输部分会被打孔(puncture)，因此会对进行eMBB业务传输的终端的下行接收信息造成一定的破坏，即数据遭到破坏。进行eMBB业务的终端在重叠部分实际接收到的是URLLC业务的信息，如果进行eMBB业务的终端不能知道其接收到的下行信息是否被打孔，可能会将重叠部分的URLLC信息与其自身已经接收到的初传或重传信息进行合并，造成错误延展，影响eMBB业务的传输性能。
可选的，所述第二指示信息的比特数根据所述第二指示信息的指示内容确定。
举例来说，当第二指示信息用于指示终端前一次接收的CBG是否遭到破坏时，第二指示信息可以为1比特，“1”表示遭到破坏，“0”表示未遭到破坏，或者反之亦然。当第二指示信息指示前一次传输CBG中的哪些CB遭到破坏时，需要至少
Figure PCTCN2018083606-appb-000001
比特或L比特指示遭到破坏的CB的编号，即L比特中的每1比特对应一个CBG中的一个CB，例如“1”表示遭到破坏，“0”表示未遭到破坏，或者反之亦然，其中L为一个CBG的前一次传输中包含的CB个数或者最大CB个数。当指示一个CBG的前一次传输中的哪些符号遭到破坏时，需要至少
Figure PCTCN2018083606-appb-000002
比特指示一个遭到破坏的符号的编号，或A比特，采用bitmap方式指示每个符号是否遭到破坏，即A比特中的每1比特对前一次传输所占用的至少1个符号中的一个符号，其中A为一个CBG的前一次传输包含的符号个数或者最大传输符号个数。当然，还可以是上述指示方式的组合，例如指示一个CBG的前一次传输中包含的CB在哪些符号遭到破坏等。
可选的，第二指示信息可以在指示域中一直存在，当然为了节省空间，第二指示信息也可以仅在下行共享信道为重传信道时即基站向终端重传数据时存在。即所述方法还包括：终端按照下述方式中的至少一种确定在所述第一指示域中是否存在所述第二指示信息或所述第二指示信息是否有效。
方式1：所述第一指示域中包含第三指示信息，所述第三指示信息用于指示所述第一指示域中是否包含所述第二指示信息或所述第二指示信息是否有效；例如“1”表示包含，“0”表示不包含，或者反之；
可选的，第二指示信息有效可以理解为终端需要读取第二指示信息，根据第二指示信息的具体指示内容进行相应的操作；无效可以理解为虽然第二指示信息的比特数存在，但不要求终端读取该第二指示信息，因此第二指示信息所指示内容是什么终端可以不知道，所以终端也不会按照第二指示信息进行相应的操作。
方式2：所述下行共享信道中包含第二指示域，所述第二指示域用于指示所述第一指示域中是否存在所述第二指示信息或所述第二指示信息是否有效。
可选的，每个CBG都可以对应一个第二指示域，即第二指示域可以独立指示每个CBG中是否包含第二指示信息或第二指示信息是否有效；例如一个CBG对应1比特第二指示域信息，为“0”时表示该CBG不包含第二指示信息或第二指示信息无效，为“1”时表示该CBG包含第二指示信息或第二指示信息有效。所有CBG也可以都对应同一个第二指示域，即下行共享信道中仅包含一个第二指示域，对所有CBG有效，例如1比特信息，为“0”时表示所有CBG都不包含第二指示信息或第二指示信息无效，为“1”时表示所有CBG都包含第二指示信息或第二指示信息有效。
方式3：用于调度所述下行共享信道的下行控制信道中存在至少1比特第五指示域，所述第五指示域用于指示所述第一指示域中是否存在所述第二指示信息或所述第二指示信息是否有效。这里的第五指示域与前述的第二指示域类似。
方式4，当判断所述下行共享信道为重传时，确定所述第一指示域中包含所述第二指示信息或所述第二指示信息有效，否则，确定所述第一指示域中不包含所述第二指示信息或所述第二指示信息无效。
具体的，可以通过用于调度所述下行共享信道的下行控制信道中的指示域判断所述下行共享信道是否为重传，例如，所述下行控制信道中所指示的HARQ进程号与前面已经接收到的一个数据包所对应的进程号相同，且所述下行控制信道中指示为重传(例如根据NDI判断为重传，或者根据下行控制信道中包含的指示CBG是否重传的指示域确定，如果有一个CBG为重传状态，则表示调度重传)；还可以根据用于调度所述下行共享信道的下行控制信道所使用的DCI格式的不同(例如比特数不同，或DCI中存在指示域指示为哪种格式)和/或所使用的RNTI不同来判断是否重传，例如使用DCI格式1为调度初传，使用DCI格式2为调度重传，DCI格式1和格式2的DCI大小不同，或者，使用RNTI1为调度初传，使用RNTI2为调度重传等，当然也可以是两者的组合。
所述终端首先根据所述方式1～4判断所述第一指示域中是否包含第二指示信息或第二指示信息是否有效，当判断包含或有效时，进一步解析/读取第二指示信息，否则，如果判断不包含，认为第一指示域中仅包含第一指示信息，如果判断无效，则第一指示域中还是包含第二指示信息，即第一指示域中总是包含第一指示信息和第二指示信息，但不要求终端进一步解析/读取第二指示信息。
可选的，所述第二指示信息也可以预定为总是存在或总是有效，即所述第一指示域中总是包含所述第二指示信息或第二指示信息总是有效，则所述终端不需要执行上述方式去确定所述第一指示域中是否包含所述第二指示信息或第二指示信息是否有效，而总是按照所述第一指示域中总是包含所述第二指示信息或第二指示信息总是有效进行处理。
对应的，下面介绍基站如何确定在所述第一指示域中是否存在所述第二指示信息或所述第二指示信息是否有效，具体如下：基站按照下述方式中的至少一种确定在所述第一指示域中是否存在所述第二指示信息或所述第二指示信息是否有效。
方式1：所述第一指示域中包含第三指示信息，所述第三指示信息用于指示所述第一指示域中是否包含所述第二指示信息或所述第二指示信息是否有效；所述基站确定所述第一指示域中是否存在所述第二指示信息或所述第二指示信息是否有效，并通过所述第三指示信息指示给终端。
方式2：所述下行共享信道中还包含第二指示域，所述第二指示域用于指示所述第一指示域中是否存在所述第二指示信息或所述第二指示信息是否有效；所述基站确定所述第一指示域中是否存在所述第二指示信息或所述第二指示信息是否有效，并通过所述第二指示域指示给终端。
方式3：用于调度所述下行共享信道的下行控制信道中存在至少1比特第五指示域，所述第五指示域用于指示所述第一指示域中是否存在所述第二指示信息或所述第二指示信息是否有效；所述基站确定所述第一指示域中是否存在所述第二指示信息或所述第二指示信息是否有效，并通过所述第五指示域指示给终端；
方式4，当判断所述下行共享信道为重传时，确定所述第一指示域中包含所述第二指示信息或所述第二指示信息有效，否则，确定所述第一指示域中不包含所述第二指示信息或所述第二指示信息无效。
关于基站确定在所述第一指示域中是否存在所述第二指示信息或所述第二指示信息是否有效的方式，请参考前述终端确定在所述第一指示域中是否存在所述第二指示信息或所述第二指示信息是否有效的方式的描述，为了说明书的简洁，在此不作赘述。
可选的，所述第三指示信息与所述第一指示域中的所述第一指示信息或所述第二指示信息独立编码；
可选的，所述第二指示域与所述第一指示域独立编码。
可选的，上述编码方式可以为使用重复编码，单一编码(simplex encoding)，瑞德-穆勒(RM，Reed-Muller)编码等。
可选的，如果终端根据所述第二指示信息确定与所述第二指示信息对应的CBG(包含该第二指示信息的第一指示域对应的CBG)所包含的所述第一指示域中的所述第一指信息所指示的CBG编号对应的CBG的前一次或前多次传输遭到破坏，那么终端清除存储的所 述CBG的前一次或前多次传输中遭到破坏的数据，或者将通过所述下行共享信道接收的所述CBG中的对应的数据覆盖所述CBG的前一次或前多次传输中遭到破坏的数据。其中，与所述第二指示信息对应的CBG包含的所述第一指示域，即该第二指示信息所在的第一指示域，或包含该第二指示信息的第一指示域。
如果遭到破坏，那么终端不将前一次或者前几次接收的CBG中对应的遭到破坏的数据与本次接收的CBG中对应的数据进行合并；即终端可以在存储器(buffer)中清除/释放掉该CBG的前一次或者前几次接收中对应的遭到破坏的数据，或者将本次接收的CBG中的相应数据替换/覆盖该CBG的前一次或者前几次接收中对应的遭到破坏的数据。其中，如果所述第二指示信息指示的是CBG级别是否遭到破坏，所述终端对前一次或前几次传输中接收到的遭到破坏的CBG不与本次接收到的对应的CBG进行HARQ合并(例如终端在buffer中释放或清除掉上一次传输中受到破坏的CBG，或将本次收到的CBG覆盖buffer中存存储的该前一次传输中CBG的信息)，如果所述第二指示信息指示的是CB级别是否遭到破坏，所述终端对该CBG的前一次或前几次传输中接收到的遭到破坏的CB不与本次接收到的该CBG的对应的CB进行HARQ合并(例如终端在buffer中释放或清除掉上一次传输中受到破坏的CB，或将本次收到的CB覆盖buffer中存存储的前一次传输中该CB的信息)，如果所述第二指示信息指示的是符号级别是否遭到破坏，所述终端对该CBG的前一次或前几次传输中接收到的遭到破坏的符号上的数据不与本次接收到的该CBG的对应的符号上的数据进行HARQ合并(例如终端在buffer中释放或清除掉上一次传输中受到破坏的符号上的数据，或将本次收到的符号上的数据覆盖buffer中存存储的相应的前一次传输中该符号上的信息)。
以下将通过举例说明本申请提供的数据传输方法的完整过程。
举例来说，假设一个TB经过码块分割得到5个CBG，CBG1、CBG2、CBG3、CBG4和CBG5各包含4个CB；终端在时隙1中接收到一个下行控制信道调度TB1在一个共享信道传输进行初传传输，该下行控制信道中指示的HARQ进程号为0，即该TB1对应的HARQ进程号为0；
一种可能的实现方式：终端可以总是假设该TB1的每个CBG中包含第一指示域，则终端在时隙1中，根据调度的TB1的TBS确定其码块分割之后的CB数即20，然后按照每个CBG包含4个CB的方式进行CBG分组，得到5个CBG，在每个CBG中的对应的资源上接收第一指示域，则每个CBG的第一指示域中的第一指示信息为3比特，指示CBG的编号从0～4，或者从1到5；如果假设第一指示域中总是包含第二指示信息，因为是初次传输，所以第二指示信息指示数据未被破坏的状态。终端对每个接收到的CBG产生反馈信息，例如ACK，NACK，ACK，NACK，ACK，发送给基站；当基站正确接收到上述反馈信息时，确定TB1初始传输中的CBG2和CBG4需要重传，则向终端发送下行控制信 道调度进行CBG2和CBG4的重传。
另一种可能的实现方式：终端根据时隙1中调度该TB1传输的下行控制信道中的指示域确定该传输为初传，则判断其中的每个CBG都不包含第一指示域；但由于终端知道该TB1初始传输的大小，因此可以确定该TB1初始传输时的CBG划分以及CBG编号，用于重传做对应合并。
另一种可能的实现方式：终端根据时隙1中调度该TB1传输的下行控制信道中的第三指示域确定TB1的重传CBG中是否包含第一指示域，较优的，在初始传输中，可以指示不包含，例如将第三指示域置为“0”。
假设终端在时隙3中接收到一个下行控制信道调度该TB1在一个共享信道传输进行重传，该下行控制信道中指示的HARQ进程号为0，即该TB1对应的HARQ进程号，根据NDI判断为TB1的重传或者根据DCI大小或RNTI判断为重传，或者如果下行控制信道中存在指示域指示至少一个CBG为重传，则判断为重传。
一种可能的实现方式：终端总是假设该TB1的每个CBG中包含第一指示域，则终端在时隙3中，根据调度的TB1重传的TBS确定其码块分割之后的CB数，然后按照每个CBG包含4个CB的方式进行CBG分组，得到2个CBG，在每个CBG中的对应的资源上接收第一指示域，假设第一指示域包含第一指示信息，则第一个CBG(为TB1的初始传输中的CBG2的重传)对应的第一指示域中的第一指示信息为“001”，表示对应的CBG为TB1的初始传输中的CBG2，则第二个CBG(为TB1的初始传输中的CBG4的重传)对应的第一指示域中的第一指示信息为“011”，表示对应的CBG为TB1的初始传输中的CBG4。即终端通过第一指示域识别每个CBG，使得终端和基站对每个重传的CBG理解一致。
如果第一指示域包含第二指示信息，此时第二指示信息可以根据TB1的初始传输中的CBG2和CBG4的数据是否遭到破坏来进行指示；假设指示CBG2的数据遭到破坏，即该重传中的第一个CBG所对应的第一指示域中的第二指示信息指示为“1”，表示遭到破坏，假设指示CBG4的数据未遭到破坏，即该重传中的第二个CBG所对应的第一指示域中的第二指示信息指示为“0”，表示未遭到破坏，终端将在时隙3中的共享信道中接收到的第一个CBG(即重传的CBG2)的信息不与在时隙1中的初始传输中接收到的存储在buffer中的CBG2的信息进行合并，避免遭到破坏的数据对重传数据的影响，终端还可以清除在时隙1中的初始传输中接收到的存储在buffer中的CBG2的信息，释放这部分buffer，终端将在时隙3中的共享信道中接收到的第二个CBG(即重传的CBG4)的信息与在时隙1中的初始传输中接收到的存储在buffer中的CBG4的信息进行合并，以提高解调性能。当然也可以通过判断为重传而确定包含第二指示信息，或者根据第一指示域中的第三指示信息判断是否包含第二指示信息，较优的，重传中可以通过第三指示信息指示包含第二指示 信息，例如第三指示信息置为“1”，或者，根据调度该TB1重传的下行控制信道中的第二指示域的指示确定是否在共享信道中的每个CBG对应的第一指示域中包含第二指示信息，较优的，重传中可以通过设置第二指示域指示包含第二指示信息，例如第二指示域置为“1”。
另一种可能的实现方式：终端根据时隙3中调度该TB1重传的下行控制信道中的指示域确定该传输为重传，则判断TB1的重传CBG中包含第一指示域；按照上述类似的方式确定重传的CBG编号以及是否数据遭到破坏；
另一种可能的实现方式：终端根据时隙3中调度该TB1重传的下行控制信道中的第三指示域确定TB1的重传CBG中是否包含第一指示域，较优的，在重传中，指示包含，例如将第三指示域置为“1”。
