技术领域
本公开文本涉及通信的技术领域，尤其涉及一种数据传输方法、资源指示信息的获取方法、终端及基站。
背景技术
在第四代移动通信技术(the 4th Generation mobile communication technology，4G)的分时长期演进(Time Division-Long Term Evolution，TD-LTE)的阶段的设计之中，物理下行控制信道(Physical Downlink Control Channel，PDCCH)传输并不是完全可靠，用户设备(User Equipment，UE)可能丢失某些下行控制信息(Downlink Control Information，DCI)，从而导致混合自动重传请求(Hybrid Automatic Repeat request，HARQ)出错率变高。为了避免这类问题，PDCCH引入了一个下行链路分配索引(Downlink Assignment Index，DAI)字段，用于告知UE在HARQ反馈窗口内有多少个子帧包含下行传输。在HARQ bundling中，还可以帮助UE检测到是否丢失了下行DCI，并避免出现丢失了某些下行DCI却反馈ACK信息的情况。在HARQ multiplexing中，DAI可以辅助UE确定需要反馈多少比特的肯定确认(ACKnowledgement，ACK)/否定确认(Negative ACKnowledgement，NACK)信息。
而在第五代移动通信技术(the 5th Generation mobile communication technology，5G)的新空口(New Radio，NR)系统中，由于一个控制NR-PDCCH有可能调度多个下行的子帧，每个下行子帧包含一个或者多个码块(Code Block，CB)，相关技术无法一次性地在NR-PDCCH中给出各个子帧或者CB的资源编号，进而终端无法准确地确定所需反馈ACK/NACK/未接 收到的非连续传输(Discontinuous Transmission，DTX)信息的比特数。

如图1所示，本公开文本的一些实施例提供了一种数据传输方法，应用于基站，包括：
步骤101：根据预设资源编号与加扰模式的对应关系，确定与下行调度资源的资源编号对应的加扰模式。
这里，通过预设资源编号与加扰模式的对应关系，确定与下行调度资源的资源编号对应的加扰模式，以便后续通过该加扰模式对数据块进行加扰。
具体地，上述步骤101可包括根据预设资源编号与加扰模式的对应关系，确定与下行调度资源的资源编号对应的加扰序列组。该加扰序列组包括沃尔什(Walsh)序列、m序列或者金(Gold)序列。当然，该加扰序列组也可包括或者其他随机序列组的一个子集。
步骤102：根据所确定的加扰模式，对上述下行调度资源所承载的数据块的CRC进行加扰。
这里，通过对CRC进行加扰的方式来隐式指示下行要指示的资源编号，达到在物理下行控制信道中同时给出多个子帧或者多个码块的资源编号的目的。
步骤103：将加扰后的上述CRC和上述数据块发送给终端。
这里，将加扰后的上述CRC和上述数据块发送给终端，使得终端对所述 加扰后的CRC进行解加扰处理，得到CRC的加扰模式；根据预设资源编号与加扰模式的对应关系，获取与所述CRC的加扰模式对应的资源编号并作为所述下行调度资源的资源编号，实现了在物理下行控制信道中同时给出多个子帧或者多个码块的资源编号的目的，并减少了信令开销。

如图2所示，本公开文本的一些实施例还提供了另一种数据传输方法，应用于基站，包括：
步骤201：确定下行调度资源的资源编号。
这里，通过确定下行调度资源的资源编号，以便后续根据资源编号确定与该下行调度资源的资源编号对应的加扰模式。
具体地，本公开文本实施例中可根据下行调度资源中子帧的数目及每个子帧中的传输块(Transport Block，TB)的数目来确定下行调度资源中每个CB的数目。
下面结合附图3-5来具体说明本公开文本实施例中确定资源编号的具体实现方式。
实现方式一
上述下行调度资源包括至少一个子帧，每个子帧包括至少一个TB，每个所述TB包括至少一个CB；
上述确定下行调度资源的资源编号，包括：
对上述下行调度资源中的每个CB进行编号，得到每个CB的CB编号，其中，上述下行调度资源中不同的CB具有不同的CB编号；根据上述CB编 号，确定下行调度资源中每个CB的资源编号。
上述实现方式一中，对下行调度资源中的所有CB进行统一编号，且不同的CB具有不同的CB编号，如图3所示，假定下行调度资源包含一个子帧(时隙)，该子帧包含一个TB，每个TB包括六个CB，此时采用上述实现方式一对上述所有的CB进行编号，得到编号0-5，终端根据该资源编号0-5，确定该多个子帧的多个码块在一个上行子帧上反馈ACK/NACK的比特数，在上行子帧上进行反馈时的格式可具体为ACK/NACK 0-5。
如图4所示，下行调度资源包含两个子帧(时隙)，每个子帧包括两个TB，每个TB包括六个CB，则对下行调度资源中的所有CB进行编号，得到编号0-23。终端根据该资源编号，确定该多个子帧的多个码块在一个上行子帧上反馈ACK/NACK的比特数。在上行子帧上进行反馈时的格式可具体为ACK/NACK 0-23。
实现方式二
所述下行调度资源包括一个子帧，每个子帧包括至少两个TB，每个所述TB包括至少两个CB；
所述确定下行调度资源的资源编号，包括：
对上述下行调度资源中的每个CB及每个TB分别进行编号，得到每个CB的CB编号及每个所述TB的TB编号，其中，下行调度资源中不同的TB具有不同的TB编号，同一TB中的不同CB具有不同的CB编号；根据所述CB的CB编号及所述CB所在TB的TB编号，确定下行调度资源中每个CB的资源编号。
上述实现方式二中，当下行调度资源中包含一个子帧，该子帧包括多个TB时，则对每个TB进行编号，并对每个TB中的多个CB单独进行编号。如图5所示，下行调度资源包含一个子帧(时隙)，该子帧包括两个TB，每个TB包括六个CB，则对两个TB分别进行编号得到两个TB编号，并对每个TB编号中的6个CB分别进行编号，得到CB编号0-5，终端根据TB编号和CB编号的组合，得到每个CB的编号，如TB1-CB0或CB0-TB1表示的是第一个TB中的第一个CB。在上行子帧上进行反馈时的格式可具体为TB1：ACK/NACK 0-5；TB2：ACK/NACK 0-5。
在对TB编号和CB编号进行组合时，可以先是TB编号，再是CB编号；也可以先是CB编号，再是TB编号。
实现方式三
所述下行调度资源包括至少两个子帧，每个子帧包括至少两个TB，每个所述TB包括至少两个CB；
所述确定下行调度资源的资源编号，包括：
对所述下行调度资源中的每个CB、每个TB及每个子帧分别进行编号，得到每个所述CB的CB编号、每个所述TB的TB编号及每个子帧的子帧编号，其中，所述下行调度资源中不同的子帧具有不同的子帧编号，同一子帧中的不同的TB具有不同的TB编号，同一TB中的不同CB具有不同的CB编号；根据所述CB的CB编号、所述CB所在TB的TB编号及所述TB所在子帧的子帧编号，确定下行调度资源中每个CB的资源编号。
如图6所示，当下行调度资源中包含多个子帧，每个子帧包括多个TB时，则对每个子帧及TB分别进行编号，并对每个TB中的多个CB单独进行编号。如图6所示，下行调度资源包含两个子帧(时隙)，每个子帧包括两个TB，每个TB包括六个CB，则对两个子帧分别进行编号得到两个子帧编号，对两个TB分别进行编号得到两个TB编号，并对每个TB编号中的6个CB分别进行编号，得到CB编号0-5，终端根据子帧编号、TB编号和CB编号的组合，得到每个CB的编号，如子帧1-TB1-CB0或CB0-TB1-子帧1表示的是第一个子帧中第一个TB中的第一个CB。在上行子帧上进行反馈时的格式可具体为子帧1-TB1：ACK/NACK 0-5；子帧1-TB2：ACK/NACK 0-5；子帧2-TB1：ACK/NACK 0-5；子帧2-TB2：ACK/NACK 0-5。
在对子帧编号、TB编号和CB编号进行组合时，可以先是子帧编号，再是TB编号，最后为CB编号；也可以先是TB编号，再是CB编号，最后为子帧编号。
步骤202：根据预设资源编号与加扰模式的对应关系，确定与下行调度资源的资源编号对应的加扰模式。
这里，根据预设资源编号与加扰模式的对应关系，确定与下行调度资源的资源编号对应的加扰模式，实现了隐式指示资源编号的目的。
如图7所示，该步骤202可具体包括：
步骤2021：若下行调度资源的资源编号与DAI的值为一一对应关系，则根据预设资源编号与加扰模式的对应关系，确定与下行调度资源的资源编号对应的加扰模式。
具体地，如图8所示，DAI的值与资源编号为一一对应关系，资源编号D4、D5、S6及D8与下行DAI＝1、下行DAI＝2、下行DAI＝3及下行DAI＝4一一对应。此时，可在下述表1中查找与资源编号对应的加扰模式，表1中保存有按照对应关系存储的资源编号的值与加扰模式的对应关系，通过查找相应的加扰序列并对相应码块所承载的数据进行CRC加扰，以实现隐式指示资源编号的目的。
Figure PCTCN2017113965-appb-000001
表1
步骤2022：若下行调度资源的资源编号与DAI的值为多对一关系，则根据预设资源编号与DAI的值的对应关系，确定与下行调度资源的资源编号对应的DAI的值，并根据所确定的DAI的值和加扰模式之间的一一对应关系，唯一确定下行调度资源的加扰模式。
具体地，如图9所示，DAI的值与资源编号为多对一关系，资源编号D4、D9、D3与下行DAI＝1对应；资源编号D5、D0与下行DAI＝2对应；资源编号S6及S7与下行DAI＝3对应；资源编号D8、D2与下行DAI＝4对应。此时，可具体建立如表2和表3所示的对应关系，并进一步根据表2或者表3增加加扰模式的对应关系，得到如表4所示的对应关系，可在下述表4中查找与资源编号对应的DAI值，再根据DAI的值和加扰模式之间的一一对应关系，唯一确定下行调度资源的加扰模式，进而实现通过CRC加扰隐式指示资 源编号的目的。

表3

表4
步骤203：根据所确定的加扰模式，对上述下行调度资源所承载的数据块的CRC进行加扰。
这里，根据所确定的每个CB对应的加扰模式，分别对每个CB所承载数据块的CRC进行加扰，达到在物理下行控制信道中同时给出多个子帧或者多个码块的资源编号的目的。
上述加扰模式指的是一个由二进制位串组成的序列{sk，k＝0，1，2，3，…}，其作用于CRC比特进行XOR运算后的比特序列为{CRC’k，k＝0，1，2，3，…}，其中，CRC’k＝CRCk+sk，上述加扰模式对应的序列均可以和一个系数仅为‘0’或‘1’取值的多项式一一对应。
为了使得检测的性能更好，循环相邻的两个DAI值对应的加扰模式要满足欧式距离尽量大；
一种方法是选用Walsh序列作为CRC加扰序列，例如对于长度为K＝2N的CRC长度，通过如下公式，生成K行K列的矩阵，并在矩阵中选取M行作为M个加扰序列分配给M个下行要接收的资源编号的值(表1)。Walsh(K)由如下公式生成：
Figure PCTCN2017113965-appb-000005
其中
Figure PCTCN2017113965-appb-000006
运算是M与N克罗内克积。
选用Walsh序列后，各个序列之间的欧式距离为K/2，具有一定的抗干扰的能力。另外，当K不是2的幂次方的时候，即K≠2N，不能适用Walsh序列，可选用其他的序列，如m序列、Gold序列或者其他序列。
步骤204：将加扰后的上述CRC和上述数据块发送给终端。
这里，将加扰后的上述CRC和上述数据块发送给终端，使得终端对所述加扰后的CRC进行解加扰处理，得到CRC的加扰模式；根据预设资源编号与加扰模式的对应关系，获取与所述CRC的加扰模式对应的资源编号并作为所述下行调度资源的资源编号，实现了在物理下行控制信道中同时给出多个子帧或者多个码块的资源编号的目的，并减少了信令开销。
本公开文本实施例的数据传输方法，基站确定下行调度资源的资源编号；根据预设资源编号与加扰模式的对应关系，确定与下行调度资源的资源编号对应的加扰模式；根据所确定的加扰模式，对下行调度资源所承载的数据块的CRC进行加扰；将加扰后的CRC和数据块发送给终端，使得终端对所述加扰后的CRC进行解加扰处理，得到CRC的加扰模式；根据预设资源编号与加扰模式的对应关系，获取与所述CRC的加扰模式对应的资源编号并作为所述下行调度资源的资源编号。本公开文本实施例采用CRC加扰的方法来隐式指示下行要指示的资源编号的方式，实现了在物理下行控制信道中同时给出多个子帧或者多个码块的资源编号的目的，同时能够减少信令开销，保证协议的可工作性。
如图10所示，本公开文本的一些实施例还提供了一种资源指示信息的获 取方法，应用于终端，包括：
步骤1001：获取基站发送的数据块及加扰后的CRC，该加扰后的CRC为基站根据预设资源编号与加扰模式的对应关系，确定与下行调度资源的资源编号对应的加扰模式后，根据所确定的加扰模式对下行调度资源所承载的数据块的CRC进行加扰得到的。
这里，终端获取上述数据块及加扰后的CRC，以便后续对该加扰后的CRC进行解加扰，以获取相应的加扰模式。
步骤1002：对上述加扰后的CRC进行解加扰处理，得到数据块的CRC的加扰模式。
这里对上述加扰后的CRC进行解加扰处理，以得到每个码块所承载的数据块的CRC对应的加扰模式。
具体地，根据所述数据块生成校验CRC；
根据多个预设加扰模式，分别对所述加扰后的CRC进行解加扰处理，得到一组解加扰后的CRC；判断所述解加扰后的CRC中是否存在与所述校验CRC相同的CRC；若存在，则将与所述校验CRC相同的CRC所对应的加扰模式，作为所述数据块的CRC的加扰模式。
假定终端根据检测到的数据部分生成校验CRC_recv，终端根据预定义的映射表格中的各个加扰模式，将之分别加扰到上述加扰后的CRC上，得到{CRC1，CRC2，CRC3，…，CRCk}，如果存在某一个k使得CRCk和CRC_recv相同，则接收成功，并将该CRCk所对应的加扰模式作为该数据块的CRC的加扰模式。
步骤1003：根据预设资源编号与加扰模式的对应关系，获取与所述CRC的加扰模式对应的资源编号，并作为所述下行调度资源的资源编号。
这里，终端获取基站采用CRC加扰的方法隐式指示的资源编号，减少了信令开销。
如图11所示，该步骤1003包括：
步骤10031：若上述下行调度资源的资源编号与DAI的值为一一对应关系，则根据第一预设映射表中预设资源编号与加扰模式的对应关系，获取与当前CB的CRC的加扰模式对应的资源编号，并作为当前CB的资源编号。
终端可通过与基站预先商定的协议来获知，下行调度资源的资源编号与DAI是一一对应关系还是多对一关系，并进而选择相应的预设映射表，该第一预设映射表中保存有预设资源编号与加扰模式的一一对应关系，终端根据每个码块对应的加扰模式便可唯一确定每个码块的资源编号，减少了信令开销。每个码块的资源编号可具体为每个CB的CB编号，或者是TB编号和CB的组合，或者子帧编号、TB编号和CB的组合。
步骤10032：若上述下行调度资源的资源编号与DAI的值为多对一关系，则根据第二预设映射表中预设资源编号、DAI的值及加扰模式之间的对应关系，获取与当前CB的CRC的加扰模式对应的资源编号，并作为所述当前CB的资源编号。
由于当资源编号比较多时，为减小信令开销，基站先将资源编号先映射到DAI的值，其中，DAI的比特数目小于资源编号的数值所要占用的比特数目，再根据DAI的值映射到相应的加扰模式，因此，终端在进行接收时，若资源编号与DAI的值为多对一关系，则需要根据上述第二预设映射表中的对应关系来获取当前CB的资源编号。
具体地，若上述下行调度资源的资源编号与DAI的值为多对一关系，则根据第二预设映射表中预设资源编号、DAI的值及加扰模式之间的对应关系，确定与当前CB的CRC的加扰模式对应的DAI的值；在所述第二预设映射表中，查找出与所确定的DAI的值对应的候选资源编号集合；根据与当前CB相邻的前一个CB的资源编号，在上述候选资源编号集合中，选取一个CB编号作为与当前CB的CRC的加扰模式对应的资源编号，并作为当前CB的资源编号。
进一步地，可在候选资源编号集合中，选取前一个CB的资源编号接近的资源编号作为当前CB的资源编号，假定DAI＝1对应的候选编号集合为(1，5，9，13)，前一个CB的资源编号为8，则确定当前CB的资源编号为9。
本公开文本实施例的终端，对所述加扰后的CRC进行解加扰处理，得到CRC的加扰模式；根据预设资源编号与加扰模式的对应关系，获取与所述CRC的加扰模式对应的资源编号，并作为下行调度资源的资源编号，得到基站采用CRC加扰的方法来隐式指示的下行要指示的资源编号，减少了信令开 销。
如图12所示，本公开文本的实施例还提供了另一种资源指示信息的获取方法，应用于终端，包括：
步骤1201：获取基站发送的数据块及加扰后的CRC，该加扰后的CRC为基站根据预设资源编号与加扰模式的对应关系，确定与下行调度资源的资源编号对应的加扰模式后，根据所确定的加扰模式对下行调度资源所承载的数据块的CRC进行加扰得到的。
步骤1202：对上述加扰后的CRC进行解加扰处理，得到数据块的CRC的加扰模式。
步骤1203：根据预设资源编号与加扰模式的对应关系，获取与所述CRC的加扰模式对应的资源编号，并作为所述下行调度资源的资源编号。
该步骤1201-1203与上述步骤1001与1003相同，此处不再赘述。
步骤1204：根据所确定的资源编号的数目，确定向基站发送的反馈信息的比特数，其中，反馈信息携带有ACK、NACK或者未接收到的DTX信息。
这里，终端根据加扰模式获取资源编号，并进而根据该资源编号确定所需向基站反馈的ACK、NACK或者为接收到的DTX的信息，有利于终端检测是否丢失下行DCI，并进一步避免出现丢失了某些下行DCI却反馈ACK的情况。
本公开文本实施例的终端，对所述加扰后的CRC进行解加扰处理，得到CRC的加扰模式；根据预设资源编号与加扰模式的对应关系，获取与所述CRC的加扰模式对应的资源编号，并作为下行调度资源的资源编号，得到基站采用CRC加扰的方法来隐式指示的下行要指示的资源编号，并进而根据该资源编号确定所需向基站反馈的ACK、NACK或者为接收到的DTX的信息，有利于终端检测是否丢失下行DCI，并进一步避免出现丢失了某些下行DCI却反馈ACK的情况。
