背景技术
在无线通信系统中，用于发送上行链路(UL)的共享数据信道的资源的选择一般是基于调度/授权的，并且调度和授权机制可以由基站控制。在具体应用过程中，用户设备向基站发送信道质量指示符(CQI)，并请求基站进行上行链路调度；当基站接收到上行链路调度请求，并获取CQI后，可以向用户设备分配资源，并且在已知精确的信号与干扰加噪声比(SINR)的基础上，在调制和编码方案(MCS)表中选择最适合的MCS，然后向用户设备通知所分配的资源和该MCS的索引；然后，用户设备利用所述MCS处理数据，并且利用所授权的资源发送该数据。上述基于调度/授权的上行链路接入方式能够与无线网络环境形成良好匹配，以利用当前网络环境获取高吞吐量，提高信道传输质量。
但是，在无需授权(without grant)的无线资源配置/重配置过程中，用户设备所采用的MCS索引对应的上行链路资源可能并非基于精确的SINR；此外，在例如5G新空口(NR)场景下，为了减少延迟并增加连接设备的数量，可能存在免授权(grant free)接入的方案，在此接入过程中也不能基于精确的SINR来确定MCS索引对应的上行链路资源。上述情况会导致在上行链路传输时，无法与当前的无线网络环境进行较好的匹配，从而无法获取更好的信道传输质量。

具体实施方式
下面将参照附图来描述根据本发明实施例的信息发送和接收方法、用户设备和基站。在附图中，相同的参考标号自始至终表示相同的元件。应当理解：这里描述的实施例仅仅是说明性的，而不应被解释为限制本发明的范围。
首先，参照图1来描述根据本发明实施例的无线通信系统。如图1所示，该无线通信系统可以包括基站10和用户设备(UE)20。UE 20可以接收基站10通过物理下行控制信道(PDCCH)和物理下行共享信道(PDSCH)发送的信息。需要认识到，尽管在图1中示出了一个基站和一个UE，但这只是示意性的，该无线通信系统可以包括一个或多个基站和一个或多个UE。此外，基站10可以是发送接收点(TRP)，或者可以利用同一个中央处理器调度管理多个TRP，在下文中，可互换地使用术语“基站”和“TRP”。
图2示出根据本发明一个实施例的信息发送方法200的流程图，所述方 法可以由用户设备执行。
如图2所示，在步骤S201中，接收指示信息，所述指示信息用于指示将待传输信息块进行分块所得到的多个子块的子块尺寸。
在本发明实施例中，待传输的信息块可以为传输块，相应地，信息块的子块的尺寸也可以为传输块的子块的尺寸。
在本发明实施例的第一实现方式中，所述指示信息可以包括各个子块对应的尺寸和/或尺寸分割比例。
在实际应用中，所述指示信息可以直接指示所划分的各个子块的尺寸，或直接指示所划分的各个子块的尺寸分割比例。或者，所述指示信息可以通过指示包含尺寸分割比例的表格中与某个/某些尺寸分割比例对应的特定内容，来间接指示各个子块的尺寸分割比例。所述表格可以由用户设备和基站两侧预先存储，可以由基站通过信令告知用户设备，或者可以由用户设备预先上报给基站，在此不做限制。
在本发明实施例的第二实现方式中，所述指示信息可以包括调制和编码方案表中的调制和编码方案索引(MCS index)和/或所述调制和编码方案索引对应的参数(例如调制阶数、目标码率和/或频谱效率等，或者后文提及的星座图映射信息)。例如，可以设置MCS索引与各个子块的子块尺寸和/或尺寸分割比例的对应关系表，使得可以通过指示信息指示的索引确定子块尺寸和/或尺寸分割比例。可替换地，可以设置传输块尺寸(TBS)分割表，该TBS分割表可以包括子块尺寸索引、与子块尺寸索引对应的子块尺寸和/或尺寸分割比例，并且MCS索引或其对应的参数可以与TBS分割表中的子块尺寸索引相对应，使得可以根据该MCS索引或其对应的参数，确定对应的子块尺寸和/或尺寸分割比例。
在上述通过MCS索引和/或对应的参数来确定各子块尺寸的实现方式中，所述MCS和/或对应的参数可以被包含在对应的MCS表中。
在一个示例中，所对应的调制和编码方案表可以为通过将第一调制和编码方案表中的一个或多个调制和编码方案索引对应的参数进行更改后得到的第二调制和编码方案表。第一调制和编码方案表可以为现有的MCS表中的一个或多个，例如为Rel-15NR的各个MCS表中的一个或多个。
在另一示例中，所对应的调制和编码方案表可以为通过在所述第一调制 和编码方案表中增加一个或多个调制和编码方案索引及其对应的参数后得到的第三调制和编码方案表。
在另一示例中，所对应的调制和编码方案表可以为基于调制和编码方案索引及其对应的参数构建得到的与第一调制和编码方案表分开的至少一个第四调制和编码方案表，其中所述第一调制和编码方案表和所述至少一个第四调制和编码方案表分别对应不同的信道条件和/或信道质量反馈条件。在这种情况下，可以根据信道条件和/或信道质量反馈条件来选择所述第一调制和编码方案表和所述至少一个第四调制和编码方案表中的表格。例如，可以设置多个第一表，分别对应较高频谱效率、较低频谱效率等情况，并且设置多个第四表，每个也分别对应较高频谱效率、较低频谱效率等情况。这样，当针对信道条件(较低可靠性要求)和信道质量反馈条件(CQI报告周期较短)的场景时，可以选择现有的第一调制和编码方案表中的具有较高频谱效率的表；当针对较高可靠性要求和CQI报告周期较短的场景时，可以选择现有的第一调制和编码方案表中的具有较低频谱效率的表；当针对较低可靠性要求和CQI报告周期较长的场景时，可以选择新建的第四调制和编码方案表中的具有较高频谱效率的表；当针对较高可靠性要求和CQI报告周期较长的场景时，可以选择第四调制和编码方案表中的具有较低频谱效率的表。当然，上述关于信道条件和信道质量反馈条件的内容仅为示例，在实际应用场景中，可以根据任何信道条件和信道质量反馈条件来对调制和编码方案表进行选择。
稍后将详细说明上文所述的第二调制和编码方案表、第三调制和编码方案表、第四调制和编码方案表。此外，第一调制和编码方案表、第二调制和编码方案表、第三调制和编码方案表、第四调制和编码方案表可以同时存在，也可以仅有其中的部分表格存在。可选地，用于选择上述表格的选择信息可以通过指示信息或RRC信令等指示给用户设备，以告知选择其中的哪个表格进行分块和/或调制。当然，针对表格的选择信息也可以由用户设备确定，并反馈给基站，在此不做限制。另外，当表格由用户设备进行选择，但并未通知给基站时，基站也可以通过盲检等方式接收用户设备所发送的发送数据，以确定所述发送数据的调制和编码方案。
在步骤S202中，根据所述指示信息将所述待传输信息块分为多个子块。
如上所述，所述指示信息可以包含各个子块对应的尺寸或尺寸分割比例。在所述指示信息包含各个子块对应的尺寸时，可以直接根据该尺寸将所述待传输信息块分为多个子块。
在所述指示信息包含各个子块对应的尺寸分割比例，可以按照下述方式将所述待传输信息块分为多个子块。
具体地，为了保证数据的正确性，在传输整个待传输信息块的情况下，需要对所述待传输信息块附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)然后传输。另一方面，在本发明的实施例中，将所述待传输信息块划分为多个子块进行传输，因此需要对每个子块附加传输附加比特进行传输。考虑到该传输附加比特，可以采用多种划分方式，例如下述两个示例方式，对待传输信息块进行分块。
具体地，待传输信息块的信息块尺寸可以表示为N info，其例如指示待传输的信息块中包含的比特数，其中，
Figure PCTCN2018098946-appb-000001
v为用户设备要传输的数据流数量，
Figure PCTCN2018098946-appb-000002
为每个物理资源块(PRB)的资源元素(RE)的量化数量，n PRB为PRB的数量，R为目标码率×[1024]，Q m为调制阶数。在此基础上，将大小为N info的待传输信息块划分为L(L≥1)个子块时，可以将各个子块的子块尺寸分别表示为N 1，N 2,…，N L。
在一个实现方式中，所述待传输信息块的信息块尺寸，可以等于各个子块的子块尺寸的和，即，
Figure PCTCN2018098946-appb-000003
这一示例能够将待传输的信息块中的所有比特通过所划分的多个子块进行传输，从而保证了最终所发送的发送数据的内容的完整性。具体地，在已知待传输信息块的信息块尺寸N info和各个子块对应的尺寸分割比例W l之后，可以将第l个子块的子块计算尺寸表示为N′ l＝N infoW l,1≤l≤L。考虑到在现有的TBS表(例如Rel-15NR的TBS表)中，包含有各已知的TBS(例如比特数目)，因此，首先可以判断所述第l个子块的子块计算尺寸N′ l是否存在于TBS表中，即，是否与TBS表中的某个TBS相同，如果存在，则认为第l个子块的子块尺寸N l就等于第l个子块的子块计算尺寸N′ l，即N l＝N′ l。如果第l个子块的子块计算尺寸N′ l的值并不在已知的TBS表中，则需要在已知的TBS表中寻找与第l个子块的子块计算尺寸N′ l最接近的值，记为
Figure PCTCN2018098946-appb-000004
对于每个子块都重复上述过程，然后 将L个子块的最接近值表示为一个最接近矢量
Figure PCTCN2018098946-appb-000005
另外，可以寻找m个满足
Figure PCTCN2018098946-appb-000006
的矢量T 1＝[N″ 1,…,N″ L]。例如，可以任取N 1，N 2,…，N L的值，使得
Figure PCTCN2018098946-appb-000007
并且将N 1，N 2,…，N L表示为T 1＝[N″ 1,…,N″ L]，重复此过程，直至获取m个满足
Figure PCTCN2018098946-appb-000008
的矢量T i＝[N″ 1,…,N″ L](i＝1～m)m为正整数。在获取到m个矢量T i之后，可以从这m个矢量T i中找出取得
Figure PCTCN2018098946-appb-000009
的第j个矢量T j，并将这一矢量T j中的各元素的值记为待传输信息块中L个子块各自的子块尺寸。以这种方式，能够在满足待传输信息块的信息块尺寸等于各个子块的子块尺寸的和的前提下，尽量保证各个子块对应的尺寸分割比例最接近实际应用场景的需求。
在另一个实现方式中，所述待传输信息块的信息块尺寸与所述待传输信息块的传输附加比特长度的和，等于各个子块的子块尺寸与各个子块的传输附加比特长度的和。这一示例能够保证在分块后所发送的发送数据与待传输信息块的发送数据的比特数相同，从而保证了相同的频谱效率。在这一个实现方式中，所述待传输信息块的信息块尺寸与所述待传输信息块的传输附加比特长度的和，等于各个子块的子块尺寸与各个子块的传输附加比特长度的和。具体地，可以将待传输信息块与各子块的尺寸表示为：
Figure PCTCN2018098946-appb-000010
Figure PCTCN2018098946-appb-000011
其中，CRC l为第l个子块的传输附加比特(此处以CRC比特为例)长度，CRC info为待传输信息块的传输附加比特长度。可以按照下述方式确定各个子块的子块尺寸。具体地，在已知待传输信息块的信息块尺寸N info和各个子块对应的尺寸分割比例W l之后，可以将第l个子块的子块计算尺寸表示为
Figure PCTCN2018098946-appb-000012
W l,1≤l≤L。考虑到在现有的TBS表(例如Rel-15NR的TBS表)中，包含有各已知的TBS(比特数目)，因此，首先可以判断所述第l个子块的子块计算尺寸N′ l是否存在于TBS表中，即，是否与TBS表中的某个TBS相同，如果存在，则认为第l个子块的子块尺寸N l就等于第l个子块的子块计算尺寸N′ l，即N l＝N′ l。如果第l个子块的子块计算尺寸N′ l的值并不在已知的TBS表中，则需要在已知的TBS表中寻找与第l个子块的子块计算尺寸N′ l最接近的值，记为

对于每个子块都重复上述过程，然后将L个子块的最接近值表示为一个最接近矢量

另外，可以寻找m个满足

Figure PCTCN2018098946-appb-000016
的矢量T 1＝[N″ 1,…,N″ L]。例如，可以任取N 1，N 2,…，N L的值， 使得
Figure PCTCN2018098946-appb-000017
并且将N 1，N 2,…，N L表示为T 1＝[N″ 1,…,N″ L]，重复此过程，直至获取m个满足
Figure PCTCN2018098946-appb-000018
Figure PCTCN2018098946-appb-000019
的矢量T i＝[N″ 1,…,N″ L](i＝1～m)，m为正整数。在获取到m个矢量T i之后，可以从这m个矢量T i中找出取得
Figure PCTCN2018098946-appb-000020
的第j个矢量T j，并将这一矢量T j中的各元素的值记为待传输信息块中L个子块各自的子块尺寸。以这种方式，能够在满足待传输信息块的信息块尺寸与所述待传输信息块的传输附加比特长度的和，等于各个子块的子块尺寸与各个子块的传输附加比特长度的和的前提下，尽量保证各个子块对应的尺寸分割比例最接近实际应用场景的需求。
可替换地，所述指示信息包括调制和编码方案表中的调制和编码方案索引(MCS index)和/或所述调制和编码方案索引对应的参数(例如调制阶数、目标码率和/或频谱效率等，或者后文提及的星座图映射信息)。在这种情况下，作为示例，MCS索引和/或对应的参数可以与TBS分割表中的子块尺寸索引相对应，从而所述根据所述指示信息将所述待传输信息块分为多个子块可以包括：根据所述调制和编码方案索引和/或所述调制和编码方案索引对应的参数，获取与其对应的子块尺寸索引，并根据所述子块尺寸索引确定各个子块的子块尺寸，其中，MCS索引和/或对应的参数所对应的调制和编码方案表可以包括前述的第一调制和编码方案表、第二调制和编码方案表、第三调制和编码方案表和/或第四调制和编码方案表。
图3(a)示出根据本发明上述实现方式的TBS索引与MCS索引对应关系的示意图；图3(b)示出根据本发明上述实现方式的TBS分割表的一个示例。如图3(a)所示，当根据所述指示信息直接获知MCS索引，或根据MCS索引对应的参数获知其对应的MCS索引之后，可以根据TBS索引与MCS索引的对应关系来确定MCS索引对应的TBS索引。随后，可以根据图3(b)中的TBS分割表确定TBS索引对应的各子块的尺寸分割比例。然后，可以按照上文所述的方式，根据各子块的尺寸分割比例将所述待传输信息块分为多个子块。当然，图3(a)和图3(b)所示仅为示例，在实际应用中，图3(a)和图3(b)中的对应关系可以用任何方式来表示，例如，也可以利用一个表格来表示图3(a)和图3(b)的各项内容。此外，图3(b)中的TBS分割表也可以不示出子块的尺寸分割比例，而替换为其他参 数，例如可以为各子块尺寸的具体比特数。图3(a)和/或图3(b)中的映射关系可以预先分别存储在基站和用户设备两端，也可以由基站通过信令告知用户设备，或者可以由用户设备预先上报给基站，在此不做限制。
在步骤S203中，对各个子块进行处理，以产生发送数据，并发送所述发送数据。
在一个实现方式中，可以对各个子块分别利用第一类型调制方式进行调制。其中，第一类型调制方式可以为相对低阶的调制方式，这里的低阶调制和之后的高阶调制为相对概念，并非对调制方式的严格限制。在本示例中，可以针对各个子块分别利用相对低阶的星座图进行映射，针对各个子块的映射方式可以相同或不同。随后，还可以针对调制后的各个子块分别利用签名(例如多址签名(MA signature))进行处理，并将处理后的发送数据进行其他处理(如果有的话)之后组合为单个数据序列并发送出去。其中，所述签名可以包括指示针对相应子块设置的功率、扩频序列、扰码序列、交织图案等中的至少一种的信息，或者可以是特定于相应子块的其他信息，在此不做限制。图4示出根据本发明这一示例的对各个子块分别利用第一类型调制方式进行调制的示意图。如图4所示，在对待传输信息块进行分块，得到子块1～子块L之后，可以对各个子块分别利用第一类型调制方式进行调制，并针对调制后的各个子块分别利用多址签名(MA signature)进行处理，然后将处理后的字块组合为单个数据序列，将其作为发送数据进行发送。在一个示例中，可以在将待传输信息块划分为多个子块之后，且在对各个子块分别利用第一类型调制方式之前，对各个子块进行信道编码。可选地，可以对各个子块分别利用前向纠错码(FEC)进行编码，例如可以对各个子块通过附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)的方式进行编码，然后再对编码后的子块分别利用第一类型调制方式进行调制。在另一个示例中，可以在将待传输信息块划分为多个子块之前，对待传输信息块进行例如前向纠错码(FEC)的信道编码。可选地，可以对待传输信息块通过附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)的方式进行编码，然后再对编码后的待传输信息块进行子块划分并分别利用第一类型调制方式进行调制。
在另一个实现方式中，还可以将所述各个子块转换为单个数据序列，并 对所述单个数据序列利用第二类型调制方式进行调制。具体地，可以将各个子块中的比特通过并串转换来转换为单个数据序列，该单个数据序列中的比特可以根据各个子块的尺寸分割比例而来源于相应的字块。例如，当第一子块的尺寸为第二子块的2倍时，可以按照例如2:1的方式分别提取第一子块和第二子块的比特，构成该单个数据序列的各比特：即，可以提取第一子块的2个比特，再提取第二子块的1个比特，构成该单个数据序列的3个比特，然后还可以用类似的方式，继续提取第一子块的后续2个比特以及第二子块的后续1个比特，以构成该单个数据序列的后续3个比特，以此类推。在将各个子块转换为单个数据序列之后，可以利用第二类型调制方式进行调制。其中，第二类型调制方式可以为相对高阶的调制方式，这里的高阶调制也为相对概念，并非对调制方式的严格限制。在本示例中，可以针对单个数据序列利用相对高阶的星座图进行映射，随后，还可以在调制后利用签名(例如MA签名(signature))进行处理，并将处理后的发送数据发送出去。例如，MA签名可以包括功率、扩频序列、扰码序列、交织图案等中的至少一种信息，当然，MA签名也可以不包括上述信息，在此不做限制。图5示出根据本发明这一示例的对转换后的单个数据序列利用第二类型调制方式进行调制的示意图。如图5所示，在对待传输信息块进行分块，得到子块1～子块L之后，可以对各个子块进行并串转换，合成为单个数据序列，并对此数据序列利用第二类型调制方式进行调制。随后，还可以针对调制后的结果利用多址签名(MA signature)进行处理，并将其作为发送数据进行发送。在一个示例中，可以在将待传输信息块划分为多个子块之后，且在将各个子块转换为单个数据序列并利用第二类型调制方式进行调制之前，对各个子块进行信道编码。可选地，可以对各个子块分别利用前向纠错码(FEC)进行编码，例如可以对各个子块通过附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)的方式进行编码，然后再将编码后的子块转换为单个数据序列并利用第二类型调制方式进行调制。在另一个示例中，可以在将待传输信息块划分为多个子块之前，对待传输信息块进行例如前向纠错码(FEC)的信道编码。可选地，可以对待传输信息块通过附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)的方式进行编码，然后再对编码后的待传输信息块进行子块划分和数据序列的转换，以利用第 二类型调制方式进行调制。
可选地，所述对所述单个数据序列利用第二类型调制方式进行调制可以包括：利用星座图映射信息，对所述单个数据序列进行映射。如上文所述，所述星座图映射信息可以被包括在所述调制和编码方案索引对应的参数中。
在一个示例中，第二类型调制方式中所采用的相对高阶的星座图可以是例如8QAM、16QAM、64QAM、128QAM等现有的星座图之一。此时，所述星座图映射信息可以包括初始星座图的信息，使得采用该初始星座图进行映射。此时，可以将所述单个数据序列划分为多个子信道，并利用初始星座图对所述单个数据序列的不同的子信道进行映射。在这种情况下，星座图映射信息还可以包括单个数据序列分别对应不同子信道的比特数，或者单个数据序列中的每个比特分别对应不同子信道的序号。例如，当采用16QAM星座图对包含4比特一组的数据序列进行映射时，可以定义两个子信道，一个子信道具有1个比特，另一个子信道具有3个比特，则星座图映射信息可以表示为：(16Q，1，3)，其分别表示16QAM星座图，一个比特组中的1个比特为第一子信道，3个比特为第二子信道。或者，星座图映射信息可以表示为(16Q，1，2，2，2)，其分别表示16QAM星座图，一个比特组中的第1比特为第一子信道，第2到4比特为第二子信道。此时，由于第二子信道比第一子信道具有的比特数多，第二子信道比第一子信道具有更大的容量，从而在传输相同数量的信息时有更高的可靠性。因此，可将具有较高优先级的数据映射到第二子信道，并将具有较低优先级的数据映射到第一子信道。每个子信道可传输独立的编码码字。
可替换地，第二类型调制方式中所采用的相对高阶的星座图可以是根据星座图映射信息生成的合成星座图。在一个示例中，所述星座图映射信息可以包括一个或多个初始星座图的信息和/或所述初始星座图对应的调整因子，其中调整因子可以包括所述初始星座图对应的功率比例和/或旋转角度。从而，对所述单个数据序列利用第二类型调制方式进行调制可以包括：利用所述初始星座图的信息、所述初始星座图对应的功率比例和/或旋转角度，生成合成星座图，利用所述合成星座图对所述单个数据序列进行映射。在上述示例中，所述初始星座图的信息可以是表示例如BPSK、QPSK、16QAM、64QAM、128QAM等星座图中的一个或多个的信息，此外，所述初始星座图的信息还 可以表示应用其指示的星座图的比特的信息。例如，可以用b 1,b 2,b 3,b 4等表示各个比特，进一步地，可以用B(b 1)、Q(b 1,b 2)或16Q(b 1,b 2,b 3,b 4)作为所述初始星座图的信息，其中B(b 1)表示用于b 1的BPSK，Q(b 1,b 2)可以表示用于b 1,b 2的QPSK，16Q(b 1,b 2,b 3,b 4)可以表示用于b 1,b 2,b 3,b 4的16QAM等。当然，也可以省略比特的表示，仅利用B表示BPSK，Q表示QPSK，16Q/M表示16QAM。以存在两个初始星座图的情况为例，与这两个初始星座图对应的功率比例可以分别为a 1和a 2，

上述功率比例和/或旋转角度可以由基站根据当前的信道反馈状况予以指示，并通过信令通知给用户设备，也可以由用户设备自行决定，在此不做限制。可选地，当单个数据序列中包含2个比特为一组的多个比特时，假设初始星座图的信息为(B,B,a 1,a 2,

图8中的合成星座图由两个QPSK星座图合成，并且功率比例为a 2的QPSK星座图旋转了
Figure PCTCN2018098946-appb-000033
如在图6-8所示的合成星座图中，可通过调整功率因子a 1和a 2的取值来调整各个星座点之间的距离，从而获取不同子信道对应的不同的可靠性，以实现速率分割，避免由于信道条件或信道反馈方式导致的信道传输性能和容量的下降。
在一个示例中，所述星座图映射信息可以来自前述的调制和编码方案索引对应的参数。具体地，指示信息可以通过指示调制和编码方案表中的调制和编码方案索引和/或所述调制和编码方案索引对应的参数，以指示相应的调制和编码方案表中所包含的星座图映射信息。
在另一个示例中，可以将所述星座图映射信息构建为一个或多个星座图映射信息表，所述星座图映射信息表中可以包含有初始星座图信息、初始星座图对应的功率比例和/或旋转角度等信息。从而，所述指示信息可以是用于指示星座图映射信息表中的星座图映射信息的指示信息，例如，所述指示信息可以通过所述星座图映射信息表中的索引来指示星座图映射信息中的初始星座图信息、初始星座图对应的功率比例和/或旋转角度。可选地，所述星座图映射信息表中可以包含有初始星座图对应的功率比例和/或旋转角度的信息，而所述指示信息可以通过所述星座图映射信息表中的索引来指示星座图映射信息中的初始星座图对应的功率比例和/或旋转角度。在这一示例中，初始星座图信息则可以通过RRC等信令另行指示。图9示出根据本发明一个实施例的星座图映射信息表。图9所示的星座图映射信息表包括了初始星座图对应的功率比例和旋转角度。具体地，星座图映射信息表中的功率比例和旋转角度信息可以通过指示信息发送的星座图映射信息索引来确定。例如，指示信息可以通过星座图映射信息表中的索引1来指示a 1和a 2的功率比例为2:1，旋转角度

根据本发明实施例的信息发送方法，能够利用基站发送的指示信息，将用户设备的待传输信息块划分为多个子块，并且对各个子块进行相应的处理，从而能够适应于不同的无线网络信道条件进行信息传输，提高信道传输质量。
以下将列举本发明实施例中关于第二调制和编码方案表、第三调制和编码方案表、第四调制和编码方案表的几个具体实现方式：
第二调制和编码方案表的实现方式
图10-12示出根据本发明实施例的第二调制和编码方案表的示例。也就是说，图10-12所示的第二调制和编码方案表是通过将已知的MCS表中的部分MCS索引对应的参数进行更改后得到的。具体地，图10中的5比特的MCS表是将已知的MCS表中MCS索引为16-31的对应参数进行更改而得到的(如阴影部分所示)。其中，以MCS索引16为例，调制阶数Q m栏中的B表示初始星座图BPSK，0.2、0.8表示两个子块中各子块的功率比例分别为0.2和0.8，pi/2表示旋转角度为π/2。在此示例中，两个初始星座图均为BPSK的情况下，代表根据上述参数所分割的两个子块的尺寸分割比例为1:1。另外，以MCS索引21为例，调制阶数Q m栏中的16Q表示16QAM星座图， 1表示第一子信道具有1比特，3表示第二子信道具有3比特。同理，图11中的5比特的MCS表是将已知的MCS表中MCS索引为16-30的对应参数进行更改而得到的(如阴影部分所示)。图12中的5比特的MCS表是将已知的MCS表中MCS索引为20-31的对应参数进行更改而得到的(如阴影部分所示)。
第三调制和编码方案表的实现方式
图13-14示出根据本发明实施例的第三调制和编码方案表的示例。图13-14所示的第三调制和编码方案表是通过在已知的MCS表中添加MCS索引及其对应的参数得到的。具体地，图13中的6比特的MCS表是在已知的5比特MCS表中添加MCS索引为28-63的对应参数而得到的(如阴影部分所示)。图14中的6比特的MCS表是在已知的5比特MCS表中添加MCS索引为29-63的对应参数而得到的(如阴影部分所示)。
第四调制和编码方案表的实现方式
图15-16示出根据本发明实施例的第四调制和编码方案表的示例。图15-16所示的调制和编码方案表是基于调制和编码方案索引及其对应的参数构建得到的与第一调制和编码方案表分开的第四调制和编码方案表。具体地，图15中的5比特的MCS表是重新构建的与已知MCS表不同的MCS索引为0-31的MCS表，其具有相对高可靠性和高频谱效率。图16中的5比特的MCS表是重新构建的与已知MCS表不同的MCS索引为0-27的MCS表，其具有相对高可靠性和低频谱效率。
图17示出根据本发明一个实施例的信息接收方法1700的流程图，所述方法可以由基站执行。
如图17所示，在步骤S1701中，发送指示信息，所述指示信息用于指示用户设备将待传输信息块进行分块所得到的多个子块的子块尺寸。
在本发明实施例中，待传输的信息块可以为传输块，相应地，信息块的子块的尺寸也可以为传输块的子块的尺寸。
在本发明实施例的第一实现方式中，所述指示信息可以包括用户设备将待传输信息块进行分块所得到的多个子块对应的尺寸和/或尺寸分割比例。
在实际应用中，所述指示信息可以直接指示所划分的各个子块的尺寸，或直接指示所划分的各个子块的尺寸分割比例。或者，所述指示信息可以通 过指示包含尺寸分割比例的表格中与某个/某些尺寸分割比例对应的特定内容，来间接指示各个子块的尺寸分割比例。所述表格可以由用户设备和基站两侧预先存储，可以由基站通过信令告知用户设备，或者可以由用户设备预先上报给基站，在此不做限制。
在上述场景的另一个示例中，所述待传输信息块的信息块尺寸与所述待传输信息块的传输附加比特长度的和，等于各个子块的子块尺寸与各个子块的传输附加比特长度的和。这一示例能够保证在分块后所发送的发送数据与待传输信息块的发送数据的比特数相同，从而保证了相同的频谱效率。
在本发明实施例的第二实现方式中，所述指示信息可以包括调制和编码方案表中的调制和编码方案索引(MCS index)和/或所述调制和编码方案索引对应的参数(例如调制阶数、目标码率和/或频谱效率等，或者后文提及的星座图映射信息)。例如，可以设置MCS索引与各个子块的子块尺寸和/或尺寸分割比例的对应关系表，使得可以通过指示信息指示的索引确定子块尺寸和/或尺寸分割比例。可替换地，可以设置传输块尺寸(TBS)表，该TBS分割表可以包括子块尺寸索引、与子块尺寸索引对应的子块尺寸和/或尺寸分割比例，并且MCS索引或其对应的参数可以与TBS分割表中的子块尺寸索引相对应，使得可以根据该MCS索引或其对应的参数，确定对应的子块尺寸和/或尺寸分割比例。
在上述通过MCS索引和/或对应的参数来确定各子块尺寸的实现方式中，所述MCS和/或对应的参数可以被包含在对应的MCS表中。
在一个示例中，所对应的调制和编码方案表可以为通过将第一调制和编码方案表中的一个或多个调制和编码方案索引对应的参数进行更改后得到的第二调制和编码方案表。第一调制和编码方案表可以为现有的MCS表中的一个或多个，例如为Rel-15NR的各个MCS表中的一个或多个。
在另一示例中，所对应的调制和编码方案表可以为通过在所述第一调制和编码方案表中增加一个或多个调制和编码方案索引及其对应的参数后得到的第三调制和编码方案表。
在另一示例中，所对应的调制和编码方案表可以为或基于调制和编码方案索引及其对应的参数构建得到的与第一调制和编码方案表分开的至少一个第四调制和编码方案表，其中所述第一调制和编码方案表和所述至少一个 第四调制和编码方案表分别对应不同的信道条件和/或信道质量反馈条件。在这种情况下，可以根据信道条件和/或信道质量反馈条件来选择所述第一调制和编码方案表和所述至少一个第四调制和编码方案表中的表格。例如，可以设置多个第一表，分别对应较高频谱效率、较低频谱效率等情况，并且设置多个第四表，每个也分别对应较高频谱效率、较低频谱效率等情况。这样，当针对信道条件(较低可靠性要求)和信道质量反馈条件(CQI报告周期较短)的场景时，可以选择现有的第一调制和编码方案表中的具有较高频谱效率的表；当针对较高可靠性要求和CQI报告周期较短的场景时，可以选择现有的第一调制和编码方案表中的具有较低频谱效率的表；当针对较低可靠性要求和CQI报告周期较长的场景时，可以选择新建的第四调制和编码方案表中的具有较高频谱效率的表；当针对较高可靠性要求和CQI报告周期较长的场景时，可以选择第四调制和编码方案表中的具有较低频谱效率的表。当然，上述关于信道条件和信道质量反馈条件的内容仅为示例，在实际应用场景中，可以根据任何信道条件和信道质量反馈条件来对调制和编码方案表进行选择。
稍后将详细说明上文所述的第二调制和编码方案表、第三调制和编码方案表、第四调制和编码方案表。此外，第一调制和编码方案表、第二调制和编码方案表、第三调制和编码方案表、第四调制和编码方案表可以同时存在，也可以仅有其中的部分表格存在。可选地，基站用于选择上述表格的选择信息可以通过指示信息或RRC信令等指示给用户设备，以告知选择其中的哪个表格进行分块和/或调制。当然，针对表格的选择信息也可以由用户设备确定，并反馈给基站，在此不做限制。另外，当表格由用户设备进行选择，但并未通知给基站时，基站也可以通过盲检等方式接收用户设备所发送的发送数据，以确定所述发送数据的调制和编码方案。
在步骤S1702中，接收用户设备的发送数据，所述发送数据由所述用户设备根据所述指示信息将所述待传输信息块分为多个子块，并对各个子块进行处理而产生。
如上所述，所述指示信息可以包含各个子块对应的尺寸或尺寸分割比例。在所述指示信息包含各个子块对应的尺寸时，可以直接根据该尺寸将所述待传输信息块分为多个子块。
在所述指示信息包含各个子块对应的尺寸分割比例，可以按照下述方式将所述待传输信息块分为多个子块。
具体地，为了保证数据的正确性，在传输整个待传输信息块的情况下，需要对所述待传输信息块附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)然后传输。另一方面，在本发明的实施例中，将所述待传输信息块划分为多个子块进行传输，因此需要对每个子块附加传输附加比特进行传输。考虑到该传输附加比特，可以采用多种划分方式，例如下述两个示例方式，对待传输信息块进行分块。
具体地，待传输信息块的信息块尺寸可以表示为N info，在此基础上，将大小为N info的待传输信息块划分为L(L≥1)个子块时，可以将各个子块的子块尺寸分别表示为N 1，N 2,…，N L。
在一个实现方式中，所述待传输信息块的信息块尺寸，可以等于各个子块的子块尺寸的和，即，
Figure PCTCN2018098946-appb-000035
这一示例能够将待传输的信息块中的所有比特通过所划分的多个子块进行传输，从而保证了最终所发送的发送数据的内容的完整性。具体地，在已知待传输信息块的信息块尺寸N info和各个子块对应的尺寸分割比例W l之后，可以将第l个子块的子块计算尺寸表示为N′ l＝N infoW l,1≤l≤L。以这种方式，能够在满足待传输信息块的信息块尺寸等于各个子块的子块尺寸的和的前提下，尽量保证各个子块对应的尺寸分割比例最接近实际应用场景的需求。
在另一个示例中，所述待传输信息块的信息块尺寸与所述待传输信息块的传输附加比特长度的和，等于各个子块的子块尺寸与各个子块的传输附加比特长度的和。这一示例能够保证在分块后所发送的发送数据与待传输信息块的发送数据的比特数相同，从而保证了相同的频谱效率。在另一个实现方式中，所述待传输信息块的信息块尺寸与所述待传输信息块的传输附加比特长度的和，等于各个子块的子块尺寸与各个子块的传输附加比特长度的和。，满足所述待传输信息块的信息块尺寸与所述待传输信息块的传输附加比特长度的和，等于各个子块的子块尺寸与各个子块的传输附加比特长度的和时，可以将待传输信息块与各子块的尺寸表示为：
Figure PCTCN2018098946-appb-000036
Figure PCTCN2018098946-appb-000037
其中，CRC l为第l个子块的传输附加比特长度，CRC info为待传输信息块的传输附加比特长度。以这种方式，能够在满足待传输信息块的信息 块尺寸与所述待传输信息块的传输附加比特长度的和，等于各个子块的子块尺寸与各个子块的传输附加比特长度的和的前提下，尽量保证各个子块对应的尺寸分割比例最接近实际应用场景的需求。
在本发明实施例的第二实现方式中，当所述指示信息包括调制和编码方案表中的调制和编码方案索引(MCS index)和/或所述调制和编码方案索引对应的参数(例如调制阶数、目标码率和/或频谱效率等，或者后文提及的星座图映射信息)时，作为示例，MCS索引和/或对应的参数可以与TBS分割表中的子块尺寸索引相对应，从而所述根据所述指示信息将所述待传输信息块分为多个子块可以包括：根据所述调制和编码方案索引和/或所述调制和编码方案索引对应的参数，获取与其对应的子块尺寸索引，并根据所述子块尺寸索引确定各个子块的子块尺寸，其中，MCS索引和/或对应的参数所对应的调制和编码方案表可以包括前述的第一调制和编码方案表、第二调制和编码方案表、第三调制和编码方案表和/或第四调制和编码方案表。
图3(a)示出根据本发明上述实现方式的TBS索引与MCS索引对应关系的示意图；图3(b)示出根据本发明上述实现方式的TBS分割表的一个示例。如图3(a)所示，当根据所述指示信息直接获知MCS索引，或根据MCS索引对应的参数获知其对应的MCS索引之后，可以根据TBS索引与MCS索引的对应关系来确定MCS索引对应的TBS索引。随后，可以根据图3(b)中的TBS分割表确定TBS索引对应的各子块的尺寸分割比例。然后，可以按照上文所述的方式，根据各子块的尺寸分割比例将所述待传输信息块分为多个子块。当然，图3(a)和图3(b)所示仅为示例，在实际应用中，图3(a)和图3(b)中的对应关系可以用任何方式来表示，例如，也可以利用一个表格来表示图3(a)和图3(b)的各项内容。此外，图3(b)中的TBS分割表也可以不示出子块的尺寸分割比例，而替换为其他参数，例如可以为各子块尺寸的具体比特数。图3(a)和/或图3(b)中的映射关系可以预先分别存储在基站和用户设备两端，也可以由基站通过信令告知用户设备，或者可以由用户设备预先上报给基站，在此不做限制。
在一个实现方式中，可以对各个子块分别利用第一类型调制方式进行调制。其中，第一类型调制方式可以为相对低阶的调制方式，这里的低阶调制和之后的高阶调制为相对概念，并非对调制方式的严格限制。在本示例中， 可以针对各个子块分别利用相对低阶的星座图进行映射，针对各个子块的映射方式可以相同或不同。随后，还可以针对调制后的各个子块分别利用签名(例如多址签名(MA signature))进行处理，并将处理后的发送数据进行其他处理(如果有的话)之后组合为单个数据序列并发送出去。其中，所述签名可以包括指示针对相应子块设置的功率、扩频序列、扰码序列、交织图案等中的至少一种的信息，或者可以是特定于相应子块的其他信息，在此不做限制。图4示出根据本发明这一示例的对各个子块分别利用第一类型调制方式进行调制的示意图。如图4所示，在对待传输信息块进行分块，得到子块1～子块L之后，可以对各个子块分别利用第一类型调制方式进行调制，并针对调制后的各个子块分别利用多址签名(MA signature)进行处理，然后将处理后的字块组合为单个数据序列，将其作为发送数据进行发送。在一个示例中，可以在将待传输信息块划分为多个子块之后，且在对各个子块分别利用第一类型调制方式之前，对各个子块进行信道编码。可选地，可以对各个子块分别利用前向纠错码(FEC)进行编码，例如可以对各个子块通过附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)的方式进行编码，然后再对编码后的子块分别利用第一类型调制方式进行调制。在另一个示例中，可以在将待传输信息块划分为多个子块之前，对待传输信息块进行例如前向纠错码(FEC)的信道编码。可选地，可以对待传输信息块通过附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)的方式进行编码，然后再对编码后的待传输信息块进行子块划分并分别利用第一类型调制方式进行调制。
在另一个实现方式中，还可以将所述各个子块转换为单个数据序列，并对所述单个数据序列利用第二类型调制方式进行调制。具体地，可以将各个子块中的比特通过并串转换来转换为单个数据序列，该单个数据序列中的比特可以根据各个子块的尺寸分割比例而来源于相应的字块。例如，当第一子块的尺寸为第二子块的2倍时，可以按照例如2:1的方式分别提取第一子块和第二子块的比特，构成该单个数据序列的各比特：即，可以提取第一子块的2个比特，再提取第二子块的1个比特，构成该单个数据序列的3个比特，然后还可以用类似的方式，继续提取第一子块的后续2个比特以及第二子块的后续1个比特，以构成该单个数据序列的后续3个比特，以此类推。在将 各个子块转换为单个数据序列之后，可以利用第二类型调制方式进行调制。其中，第二类型调制方式可以为相对高阶的调制方式，这里的高阶调制也为相对概念，并非对调制方式的严格限制。在本示例中，可以针对单个数据序列利用相对高阶的星座图进行映射，随后，还可以在调制后利用签名(例如MA签名(signature))进行处理，并将处理后的发送数据发送出去。例如，MA签名可以包括功率、扩频序列、扰码序列、交织图案等中的至少一种信息，当然，MA签名也可以不包括上述信息，在此不做限制。图5示出根据本发明这一示例的对转换后的单个数据序列利用第二类型调制方式进行调制的示意图。如图5所示，在对待传输信息块进行分块，得到子块1～子块L之后，可以对各个子块进行并串转换，合成为单个数据序列，并对此数据序列利用第二类型调制方式进行调制。随后，还可以针对调制后的结果利用多址签名(MA signature)进行处理，并将其作为发送数据进行发送。在一个示例中，可以在将待传输信息块划分为多个子块之后，且在将各个子块转换为单个数据序列并利用第二类型调制方式进行调制之前，对各个子块进行信道编码。可选地，可以对各个子块分别利用前向纠错码(FEC)进行编码，例如可以对各个子块通过附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)的方式进行编码，然后再将编码后的子块转换为单个数据序列并利用第二类型调制方式进行调制。在另一个示例中，可以在将待传输信息块划分为多个子块之前，对待传输信息块进行例如前向纠错码(FEC)的信道编码。可选地，可以对待传输信息块通过附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)的方式进行编码，然后再对编码后的待传输信息块进行子块划分和数据序列的转换，以利用第二类型调制方式进行调制。
可选地，所述调制和编码方案索引值对应的参数包括所述星座图映射信息；所述发送数据通过对所述单个比特序列利用所述星座图映射信息进行映射而产生。
在一个示例中，第二类型调制方式中所采用的相对高阶的星座图可以是例如8QAM、16QAM、64QAM、128QAM等现有的星座图之一。此时，所述星座图映射信息可以包括初始星座图的信息，使得采用该初始星座图进行映射。此时，可以将所述单个数据序列划分为多个子信道，并利用初始星座 图对所述单个数据序列的不同的子信道进行映射。在这种情况下，星座图映射信息还可以包括单个数据序列分别对应不同子信道的比特数，或者单个数据序列中的每个比特分别对应不同子信道的序号。例如，当采用16QAM星座图对包含4比特一组的数据序列进行映射时，可以定义两个子信道，一个子信道具有1个比特，另一个子信道具有3个比特，则星座图映射信息可以表示为：(16Q，1，3)，其分别表示16QAM星座图，一个比特组中的1个比特为第一子信道，3个比特为第二子信道。或者，星座图映射信息可以表示为(16Q，1，2，2，2)，其分别表示16QAM星座图，一个比特组中的第1比特为第一子信道，第2到4比特为第二子信道。此时，由于第二子信道比第一子信道具有的比特数多，第二子信道比第一子信道具有更大的容量，从而在传输相同数量的信息时有更高的可靠性。因此，可将具有较高优先级的数据映射到第二子信道，并将具有较低优先级的数据映射到第一子信道。每个子信道可传输独立的编码码字。
可替换地，第二类型调制方式中所采用的相对高阶的星座图可以是根据星座图映射信息生成的合成星座图。在一个示例中，所述星座图映射信息可以包括一个或多个初始星座图的信息和/或所述初始星座图对应的调整因子，其中调整因子可以包括所述初始星座图对应的功率比例和/或旋转角度。从而，对所述单个数据序列利用第二类型调制方式进行调制可以包括：利用所述初始星座图的信息、所述初始星座图对应的功率比例和/或旋转角度，生成合成星座图，利用所述合成星座图对所述单个数据序列进行映射。在上述示例中，所述初始星座图的信息可以是表示例如BPSK、QPSK、16QAM、64QAM、128QAM等星座图中的一个或多个的信息，此外，所述初始星座图的信息还可以表示应用其指示的星座图的比特的信息。例如，可以用b 1,b 2,b 3,b 4等表示各个比特，进一步地，可以用B(b 1)、Q(b 1,b 2)或16Q(b 1,b 2,b 3,b 4)作为所述初始星座图的信息，其中B(b 1)表示用于b 1的BPSK，Q(b 1,b 2)可以表示用于b 1,b 2的QPSK，16Q(b 1,b 2,b 3,b 4)可以表示用于b 1,b 2,b 3,b 4的16QAM等。当然，也可以省略比特的表示，仅利用B表示BPSK，Q表示QPSK，16Q/M表示16QAM。以存在两个初始星座图的情况为例，与这两个初始星座图对应的功率比例可以分别为a 1和a 2，

上述功率比例和/或旋转角度可以由基站根据当前的信道反馈状 况予以指示，并通过信令通知给用户设备，也可以由用户设备自行决定，在此不做限制。可选地，当单个数据序列中包含2个比特为一组的多个比特时，假设初始星座图的信息为(B,B,a 1,a 2,

图8中的合成星座图由两个QPSK星座图合成，并且功率比例为a 2的QPSK星座图旋转了

如在图6-8所示的合成星座图中，可通过调整功率因子a 1和a 2的取值来调整各个星座点之间的距离，从而获取不同子信道对应的不同的可靠性，以实现速率分割，避免由于信道条件或信道反馈方式导致的信道传输性能和容量的下降。
在一个示例中，所述星座图映射信息可以来自前述的调制和编码方案索引对应的参数。具体地，指示信息可以通过指示调制和编码方案表中的调制和编码方案索引和/或所述调制和编码方案索引对应的参数，以指示相应的调制和编码方案表中所包含的星座图映射信息。
在另一个示例中，可以将所述星座图映射信息构建为一个或多个星座图映射信息表，所述星座图映射信息表中可以包含有初始星座图信息、初始星座图对应的功率比例和/或旋转角度等信息。从而，所述指示信息可以是用于指示星座图映射信息表中的星座图映射信息的指示信息，例如，所述指示信息可以通过所述星座图映射信息表中的索引来指示星座图映射信息中的初始星座图信息、初始星座图对应的功率比例和/或旋转角度。可选地，所述星座图映射信息表中可以包含有初始星座图对应的功率比例和/或旋转角度的信息，而所述指示信息可以通过所述星座图映射信息表中的索引来指示星座 图映射信息中的初始星座图对应的功率比例和/或旋转角度。在这一示例中，初始星座图信息则可以通过RRC等信令另行指示。图9示出根据本发明一个实施例的星座图映射信息表。图9所示的星座图映射信息表包括了初始星座图对应的功率比例和旋转角度。具体地，星座图映射信息表中的功率比例和旋转角度信息可以通过指示信息发送的星座图映射信息索引来确定。例如，指示信息可以通过星座图映射信息表中的索引1来指示a 1和a 2的功率比例为2:1，旋转角度

以下参照图18来描述根据本申请实施例的用户设备。该用户设备可以执行上述信息发送方法。由于该用户设备的操作与上文所述的信息发送方法的各个步骤基本相同，因此在这里只对其进行简要的描述，而省略对相同内容的重复描述。
如图18所示，用户设备1800包括接收单元1810、分块单元1820和发送单元1830。需要认识到，图18仅示出与本申请的实施例相关的部件，而省略了其他部件，但这只是示意性的，根据需要，用户设备1800可以包括其他部件。
接收单元1810接收指示信息，所述指示信息用于指示将待传输信息块进行分块所得到的多个子块的子块尺寸。

具体地，为了保证数据的正确性，在传输整个待传输信息块的情况下，需要对所述待传输信息块附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)然后传输。另一方面，在本发明的实施例中，将所述待传输信息块划分为多个子块进行传输，因此需要对每个子块附加传输附加比特进行传输。考虑到该传输附加比特，可以采用多种划分方式，例如下述两个示例方式，对待传输信息块进行分块。
在一个示例中，待传输信息块的信息块尺寸可以表示为N info，其例如指示待传输的信息块中包含的比特数，其中，

为每个物理资源块(PRB)的资源元素(RE)的量化数量，n PRB为PRB的数量，R为目标码率×[1024]，Q m为调制阶数。在此基础上，将大小为N info的待传输信息块划分为L(L≥1)个子块时，可以将各个子块的子块尺寸分别表示为N 1，N 2,…，N L。
在一个实现方式中，所述待传输信息块的信息块尺寸，可以等于各个子块的子块尺寸的和，即，
Figure PCTCN2018098946-appb-000054
这一示例能够将待传输的信息块中的所有比特通过所划分的多个子块进行传输，从而保证了最终所发送的发送数据的内容的完整性。具体地，在已知待传输信息块的信息块尺寸N info和各个子块对应的尺寸分割比例W l之后，可以将第l个子块的子块计算尺寸表示为N′ l＝N infoW l,1≤l≤L。以这种方式，能够在满足待传输信息块的信息块尺寸等于各个子块的子块尺寸的和的前提下，尽量保证各个子块对应的尺寸分割比例最接近实际应用场景的需求。
在另一个实现方式中，所述待传输信息块的信息块尺寸与所述待传输信息块的传输附加比特长度的和，等于各个子块的子块尺寸与各个子块的传输附加比特长度的和。以这种方式，能够在满足待传输信息块的信息块尺寸与所述待传输信息块的传输附加比特长度的和，等于各个子块的子块尺寸与各个子块的传输附加比特长度的和的前提下，尽量保证各个子块对应的尺寸分割比例最接近实际应用场景的需求。
可替换地，所述指示信息包括调制和编码方案表中的调制和编码方案索引(MCS index)和/或所述调制和编码方案索引对应的参数(例如调制阶数、目标码率和/或频谱效率等，或者后文提及的星座图映射信息)。在这种情况下，作为示例，MCS索引和/或对应的参数可以与TBS分割表中的子块尺寸索引相对应，从而所述根据所述指示信息将所述待传输信息块分为多个子块可以包括：根据所述调制和编码方案索引和/或所述调制和编码方案索引对应的参数，获取与其对应的子块尺寸索引，并根据所述子块尺寸索引确定各个子块的子块尺寸，其中，MCS索引和/或对应的参数所对应的调制和编码方案表可以包括前述的第一调制和编码方案表、第二调制和编码方案表、第三调制和编码方案表和/或第四调制和编码方案表。
图3(a)示出根据本发明上述实现方式的TBS索引与MCS索引对应关 系的示意图；图3(b)示出根据本发明上述实现方式的TBS分割表的一个示例。如图3(a)所示，当根据所述指示信息直接获知MCS索引，或根据MCS索引对应的参数获知其对应的MCS索引之后，可以根据TBS索引与MCS索引的对应关系来确定MCS索引对应的TBS索引。随后，可以根据图3(b)中的TBS分割表确定TBS索引对应的各子块的尺寸分割比例。然后，可以按照上文所述的方式，根据各子块的尺寸分割比例将所述待传输信息块分为多个子块。当然，图3(a)和图3(b)所示仅为示例，在实际应用中，图3(a)和图3(b)中的对应关系可以用任何方式来表示，例如，也可以利用一个表格来表示图3(a)和图3(b)的各项内容。此外，图3(b)中的TBS分割表也可以不示出子块的尺寸分割比例，而替换为其他参数，例如可以为各子块尺寸的具体比特数。图3(a)和/或图3(b)中的映射关系可以预先分别存储在基站和用户设备两端，也可以由基站通过信令告知用户设备，或者可以由用户设备预先上报给基站，在此不做限制。
发送单元1830对各个子块进行处理，以产生发送数据，并发送所述发送数据。
在一个实现方式中，可以对各个子块分别利用第一类型调制方式进行调制。其中，第一类型调制方式可以为相对低阶的调制方式，这里的低阶调制和之后的高阶调制为相对概念，并非对调制方式的严格限制。在本示例中，可以针对各个子块分别利用相对低阶的星座图进行映射，针对各个子块的映射方式可以相同或不同。随后，还可以针对调制后的各个子块分别利用签名(例如多址签名(MA signature))进行处理，并将处理后的发送数据进行其他处理(如果有的话)之后组合为单个数据序列并发送出去。其中，所述签名可以包括指示针对相应子块设置的功率、扩频序列、扰码序列、交织图案等中的至少一种的信息，或者可以是特定于相应子块的其他信息，在此不做限制。图4示出根据本发明这一示例的对各个子块分别利用第一类型调制方式进行调制的示意图。如图4所示，在对待传输信息块进行分块，得到子块1～子块L之后，可以对各个子块分别利用第一类型调制方式进行调制，并针对调制后的各个子块分别利用多址签名(MA signature)进行处理，然后将处理后的字块组合为单个数据序列，将其作为发送数据进行发送。在一个示例中，用户设备可以在将待传输信息块划分为多个子块之后，且在对各个子 块分别利用第一类型调制方式之前，对各个子块进行信道编码。可选地，可以对各个子块分别利用前向纠错码(FEC)进行编码，例如可以对各个子块通过附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)的方式进行编码，然后再对编码后的子块分别利用第一类型调制方式进行调制。在另一个示例中，可以在将待传输信息块划分为多个子块之前，对待传输信息块进行例如前向纠错码(FEC)的信道编码。可选地，可以对待传输信息块通过附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)的方式进行编码，然后再对编码后的待传输信息块进行子块划分并分别利用第一类型调制方式进行调制。
在另一个实现方式中，还可以将所述各个子块转换为单个数据序列，并对所述单个数据序列利用第二类型调制方式进行调制。具体地，可以将各个子块中的比特通过并串转换来转换为单个数据序列，该单个数据序列中的比特可以根据各个子块的尺寸分割比例而来源于相应的字块。例如，当第一子块的尺寸为第二子块的2倍时，可以按照例如2:1的方式分别提取第一子块和第二子块的比特，构成该单个数据序列的各比特：即，可以提取第一子块的2个比特，再提取第二子块的1个比特，构成该单个数据序列的3个比特，然后还可以用类似的方式，继续提取第一子块的后续2个比特以及第二子块的后续1个比特，以构成该单个数据序列的后续3个比特，以此类推。在将各个子块转换为单个数据序列之后，可以利用第二类型调制方式进行调制。其中，第二类型调制方式可以为相对高阶的调制方式，这里的高阶调制也为相对概念，并非对调制方式的严格限制。在本示例中，可以针对单个数据序列利用相对高阶的星座图进行映射，随后，还可以在调制后利用签名(例如MA签名(signature))进行处理，并将处理后的发送数据发送出去。例如，MA签名可以包括功率、扩频序列、扰码序列、交织图案等中的至少一种信息，当然，MA签名也可以不包括上述信息，在此不做限制。图5示出根据本发明这一示例的对转换后的单个数据序列利用第二类型调制方式进行调制的示意图。如图5所示，在对待传输信息块进行分块，得到子块1～子块L之后，可以对各个子块进行并串转换，合成为单个数据序列，并对此数据序列利用第二类型调制方式进行调制。随后，还可以针对调制后的结果利用多址签名(MA signature)进行处理，并将其作为发送数据进行发送。在一个 示例中，用户设备可以在将待传输信息块划分为多个子块之后，且在将各个子块转换为单个数据序列并利用第二类型调制方式进行调制之前，对各个子块进行信道编码。可选地，可以对各个子块分别利用前向纠错码(FEC)进行编码，例如可以对各个子块通过附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)的方式进行编码，然后再将编码后的子块转换为单个数据序列并利用第二类型调制方式进行调制。在另一个示例中，可以在将待传输信息块划分为多个子块之前，对待传输信息块进行例如前向纠错码(FEC)的信道编码。可选地，可以对待传输信息块通过附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)的方式进行编码，然后再对编码后的待传输信息块进行子块划分和数据序列的转换，以利用第二类型调制方式进行调制。
可选地，所述对所述单个数据序列利用第二类型调制方式进行调制可以包括：利用星座图映射信息，对所述单个数据序列进行映射。如上文所述，所述星座图映射信息可以被包括在所述调制和编码方案索引对应的参数中。
在一个示例中，第二类型调制方式中所采用的相对高阶的星座图可以是例如8QAM、16QAM、64QAM、128QAM等现有的星座图之一。此时，所述星座图映射信息可以包括初始星座图的信息，使得采用该初始星座图进行映射。此时，可以将所述单个数据序列划分为多个子信道，并利用初始星座图对所述单个数据序列的不同的子信道进行映射。在这种情况下，星座图映射信息还可以包括单个数据序列分别对应不同子信道的比特数，或者单个数据序列中的每个比特分别对应不同子信道的序号。例如，当采用16QAM星座图对包含4比特一组的数据序列进行映射时，可以定义两个子信道，一个子信道具有1个比特，另一个子信道具有3个比特，则星座图映射信息可以表示为：(16Q，1，3)，其分别表示16QAM星座图，一个比特组中的1个比特为第一子信道，3个比特为第二子信道。或者，星座图映射信息可以表示为(16Q，1，2，2，2)，其分别表示16QAM星座图，一个比特组中的第1比特为第一子信道，第2到4比特为第二子信道。此时，由于第二子信道比第一子信道具有的比特数多，第二子信道比第一子信道具有更大的容量，从而在传输相同数量的信息时有更高的可靠性。因此，可将具有较高优先级的数据映射到第二子信道，并将具有较低优先级的数据映射到第一子信道。 每个子信道可传输独立的编码码字。
可替换地，第二类型调制方式中所采用的相对高阶的星座图可以是根据星座图映射信息生成的合成星座图。在一个示例中，所述星座图映射信息可以包括一个或多个初始星座图的信息和/或所述初始星座图对应的调整因子，其中调整因子可以包括所述初始星座图对应的功率比例和/或旋转角度。从而，对所述单个数据序列利用第二类型调制方式进行调制可以包括：利用所述初始星座图的信息、所述初始星座图对应的功率比例和/或旋转角度，生成合成星座图，利用所述合成星座图对所述单个数据序列进行映射。在上述示例中，所述初始星座图的信息可以是表示例如BPSK、QPSK、16QAM、64QAM、128QAM等星座图中的一个或多个的信息，此外，所述初始星座图的信息还可以表示应用其指示的星座图的比特的信息。例如，可以用b 1,b 2,b 3,b 4等表示各个比特，进一步地，可以用B(b 1)、Q(b 1,b 2)或16Q(b 1,b 2,b 3,b 4)作为所述初始星座图的信息，其中B(b 1)表示用于b 1的BPSK，Q(b 1,b 2)可以表示用于b 1,b 2的QPSK，16Q(b 1,b 2,b 3,b 4)可以表示用于b 1,b 2,b 3,b 4的16QAM等。当然，也可以省略比特的表示，仅利用B表示BPSK，Q表示QPSK，16Q/M表示16QAM。以存在两个初始星座图的情况为例，与这两个初始星座图对应的功率比例可以分别为a 1和a 2，

上述功率比例和/或旋转角度可以由基站根据当前的信道反馈状况予以指示，并通过信令通知给用户设备，也可以由用户设备自行决定，在此不做限制。可选地，当单个数据序列中包含2个比特为一组的多个比特时，假设初始星座图的信息为(B,B,a 1,a 2,

图8中的合成星座图由两个QPSK星座图合成，并且功率比例为a 2的QPSK星座图旋转了

如在图6-8所示的合成星座图中，可通过调整功率因子a 1和a 2的取值来调整各个星座点之间的距离，从而获取不同子信道对应的不同的可靠性，以实现速率分割，避免由于信道条件或信道反馈方式导致的信道传输性能和容量的下降。
在一个示例中，所述星座图映射信息可以来自前述的调制和编码方案索引对应的参数。具体地，指示信息可以通过指示调制和编码方案表中的调制和编码方案索引和/或所述调制和编码方案索引对应的参数，以指示相应的调制和编码方案表中所包含的星座图映射信息。
在另一个示例中，可以将所述星座图映射信息构建为一个或多个星座图映射信息表，所述星座图映射信息表中可以包含有初始星座图信息、初始星座图对应的功率比例和/或旋转角度等信息。从而，所述指示信息可以是用于指示星座图映射信息表中的星座图映射信息的指示信息，例如，所述指示信息可以通过所述星座图映射信息表中的索引来指示星座图映射信息中的初始星座图信息、初始星座图对应的功率比例和/或旋转角度。可选地，所述星座图映射信息表中可以包含有初始星座图对应的功率比例和/或旋转角度的信息，而所述指示信息可以通过所述星座图映射信息表中的索引来指示星座图映射信息中的初始星座图对应的功率比例和/或旋转角度。在这一示例中，初始星座图信息则可以通过RRC等信令另行指示。图9示出根据本发明一个实施例的星座图映射信息表。图9所示的星座图映射信息表包括了初始星座图对应的功率比例和旋转角度。具体地，星座图映射信息表中的功率比例和旋转角度信息可以通过指示信息发送的星座图映射信息索引来确定。例如，指示信息可以通过星座图映射信息表中的索引1来指示a 1和a 2的功率比例为2:1，旋转角度

根据本发明实施例的用户设备，能够利用基站发送的指示信息，将将用户设备的待传输信息块划分为多个子块，并且对各个子块进行相应的处理，从而能够适应于不同的无线网络信道条件进行信息传输，提高信道传输质量。
以下参照图19来描述根据本申请实施例的基站。该基站可以执行上述信息接收方法。由于该基站的操作与上文所述的信息接收方法的各个步骤基 本相同，因此在这里只对其进行简要的描述，而省略对相同内容的重复描述。
如图19所示，基站1900包括发送单元1910和接收单元1920。需要认识到，图19仅示出与本申请的实施例相关的部件，而省略了其他部件，但这只是示意性的，根据需要，基站1900可以包括其他部件。
发送单元1910发送指示信息，所述指示信息用于指示用户设备将待传输信息块进行分块所得到的多个子块的子块尺寸。
在本发明实施例中，待传输的信息块可以为传输块，相应地，信息块的子块的尺寸也可以为传输块的子块的尺寸。
在本发明实施例中，待传输的信息块可以为传输块，相应地，信息块的子块的尺寸也可以为传输块的子块的尺寸。
在本发明实施例的第一实现方式中，所述指示信息可以包括用户设备将待传输信息块进行分块所得到的多个子块对应的尺寸和/或尺寸分割比例。
在实际应用中，所述指示信息可以直接指示所划分的各个子块的尺寸，或直接指示所划分的各个子块的尺寸分割比例。或者，所述指示信息可以通过指示包含尺寸分割比例的表格中与某个/某些尺寸分割比例对应的特定内容，来间接指示各个子块的尺寸分割比例。所述表格可以由用户设备和基站两侧预先存储，可以由基站通过信令告知用户设备，或者可以由用户设备预先上报给基站，在此不做限制。
在上述场景的另一个示例中，所述待传输信息块的信息块尺寸与所述待传输信息块的传输附加比特长度的和，等于各个子块的子块尺寸与各个子块的传输附加比特长度的和。这一示例能够保证在分块后所发送的发送数据与待传输信息块的发送数据的比特数相同，从而保证了相同的频谱效率。
在本发明实施例的第二实现方式中，所述指示信息可以包括调制和编码方案表中的调制和编码方案索引(MCS index)和/或所述调制和编码方案索引对应的参数(例如调制阶数、目标码率和/或频谱效率等，或者后文提及的星座图映射信息)。例如，可以设置MCS索引与各个子块的子块尺寸和/或尺寸分割比例的对应关系表，使得可以通过指示信息指示的索引确定子块尺寸和/或尺寸分割比例。可替换地，可以设置传输块尺寸(TBS)表，该TBS分割表可以包括子块尺寸索引、与子块尺寸索引对应的子块尺寸和/或尺寸分割比例，并且MCS索引或其对应的参数可以与TBS分割表中的子块尺寸索 引相对应，使得可以根据该MCS索引或其对应的参数，确定对应的子块尺寸和/或尺寸分割比例。
在上述通过MCS索引和/或对应的参数来确定各子块尺寸的实现方式中，所述MCS和/或对应的参数可以被包含在对应的MCS表中。
在一个示例中，所对应的调制和编码方案表可以为通过将第一调制和编码方案表中的一个或多个调制和编码方案索引对应的参数进行更改后得到的第二调制和编码方案表。第一调制和编码方案表可以为现有的MCS表中的一个或多个，例如为Rel-15NR的各个MCS表中的一个或多个。
在另一示例中，所对应的调制和编码方案表可以为通过在所述第一调制和编码方案表中增加一个或多个调制和编码方案索引及其对应的参数后得到的第三调制和编码方案表。
在另一示例中，所对应的调制和编码方案表可以为或基于调制和编码方案索引及其对应的参数构建得到的与第一调制和编码方案表分开的至少一个第四调制和编码方案表，其中所述第一调制和编码方案表和所述至少一个第四调制和编码方案表分别对应不同的信道条件和/或信道质量反馈条件。在这种情况下，可以根据信道条件和/或信道质量反馈条件来选择所述第一调制和编码方案表和所述至少一个第四调制和编码方案表中的表格。例如，可以设置多个第一表，分别对应较高频谱效率、较低频谱效率等情况，并且设置多个第四表，每个也分别对应较高频谱效率、较低频谱效率等情况。这样，当针对信道条件(较低可靠性要求)和信道质量反馈条件(CQI报告周期较短)的场景时，可以选择现有的第一调制和编码方案表中的具有较高频谱效率的表；当针对较高可靠性要求和CQI报告周期较短的场景时，可以选择现有的第一调制和编码方案表中的具有较低频谱效率的表；当针对较低可靠性要求和CQI报告周期较长的场景时，可以选择新建的第四调制和编码方案表中的具有较高频谱效率的表；当针对较高可靠性要求和CQI报告周期较长的场景时，可以选择第四调制和编码方案表中的具有较低频谱效率的表。当然，上述关于信道条件和信道质量反馈条件的内容仅为示例，在实际应用场景中，可以根据任何信道条件和信道质量反馈条件来对调制和编码方案表进行选择。
稍后将详细说明上文所述的第二调制和编码方案表、第三调制和编码方 案表、第四调制和编码方案表。此外，第一调制和编码方案表、第二调制和编码方案表、第三调制和编码方案表、第四调制和编码方案表可以同时存在，也可以仅有其中的部分表格存在。可选地，基站用于选择上述表格的选择信息可以通过指示信息或RRC信令等指示给用户设备，以告知选择其中的哪个表格进行分块和/或调制。当然，针对表格的选择信息也可以由用户设备确定，并反馈给基站，在此不做限制。另外，当表格由用户设备进行选择，但并未通知给基站时，基站也可以通过盲检等方式接收用户设备所发送的发送数据，以确定所述发送数据的调制和编码方案。
接收单元1920接收用户设备的发送数据，所述发送数据由所述用户设备根据所述指示信息将所述待传输信息块分为多个子块，并对各个子块进行处理而产生。
如上所述，所述指示信息可以包含各个子块对应的尺寸或尺寸分割比例。在所述指示信息包含各个子块对应的尺寸时，可以直接根据该尺寸将所述待传输信息块分为多个子块。
在所述指示信息包含各个子块对应的尺寸分割比例，可以按照下述方式将所述待传输信息块分为多个子块。
具体地，为了保证数据的正确性，在传输整个待传输信息块的情况下，需要对所述待传输信息块附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)然后传输。另一方面，在本发明的实施例中，将所述待传输信息块划分为多个子块进行传输，因此需要对每个子块附加传输附加比特进行传输。考虑到该传输附加比特，可以采用多种划分方式，例如下述两个示例方式，对待传输信息块进行分块。
具体地，待传输信息块的信息块尺寸可以表示为N info，在此基础上，将大小为N info的待传输信息块划分为L(L≥1)个子块时，可以将各个子块的子块尺寸分别表示为N 1，N 2,…，N L。
在一个实现方式中，所述待传输信息块的信息块尺寸，可以等于各个子块的子块尺寸的和，即，

这一示例能够将待传输的信息块中的所有比特通过所划分的多个子块进行传输，从而保证了最终所发送的发送数据的内容的完整性。具体地，在已知待传输信息块的信息块尺寸N info和各个子块对应的尺寸分割比例W l之后，可以将第l个子块的子块计算尺 寸表示为N′ l＝N infoW l,1≤l≤L。以这种方式，能够在满足待传输信息块的信息块尺寸等于各个子块的子块尺寸的和的前提下，尽量保证各个子块对应的尺寸分割比例最接近实际应用场景的需求。
在另一个示例中，所述待传输信息块的信息块尺寸与所述待传输信息块的传输附加比特长度的和，等于各个子块的子块尺寸与各个子块的传输附加比特长度的和。这一示例能够保证在分块后所发送的发送数据与待传输信息块的发送数据的比特数相同，从而保证了相同的频谱效率。在另一个实现方式中，所述待传输信息块的信息块尺寸与所述待传输信息块的传输附加比特长度的和，等于各个子块的子块尺寸与各个子块的传输附加比特长度的和。，满足所述待传输信息块的信息块尺寸与所述待传输信息块的传输附加比特长度的和，等于各个子块的子块尺寸与各个子块的传输附加比特长度的和时，可以将待传输信息块与各子块的尺寸表示为：

Figure PCTCN2018098946-appb-000071
其中，CRC l为第l个子块的传输附加比特长度，CRC info为待传输信息块的传输附加比特长度。以这种方式，能够在满足待传输信息块的信息块尺寸与所述待传输信息块的传输附加比特长度的和，等于各个子块的子块尺寸与各个子块的传输附加比特长度的和的前提下，尽量保证各个子块对应的尺寸分割比例最接近实际应用场景的需求。
在本发明实施例的第二实现方式中，当所述指示信息包括调制和编码方案表中的调制和编码方案索引(MCS index)和/或所述调制和编码方案索引对应的参数(例如调制阶数、目标码率和/或频谱效率等，或者后文提及的星座图映射信息)时，作为示例，MCS索引和/或对应的参数可以与TBS分割表中的子块尺寸索引相对应，从而所述根据所述指示信息将所述待传输信息块分为多个子块可以包括：根据所述调制和编码方案索引和/或所述调制和编码方案索引对应的参数，获取与其对应的子块尺寸索引，并根据所述子块尺寸索引确定各个子块的子块尺寸，其中，MCS索引和/或对应的参数所对应的调制和编码方案表可以包括前述的第一调制和编码方案表、第二调制和编码方案表、第三调制和编码方案表和/或第四调制和编码方案表。
图3(a)示出根据本发明上述实现方式的TBS索引与MCS索引对应关系的示意图；图3(b)示出根据本发明上述实现方式的TBS分割表的一个示例。如图3(a)所示，当根据所述指示信息直接获知MCS索引，或根据 MCS索引对应的参数获知其对应的MCS索引之后，可以根据TBS索引与MCS索引的对应关系来确定MCS索引对应的TBS索引。随后，可以根据图3(b)中的TBS分割表确定TBS索引对应的各子块的尺寸分割比例。然后，可以按照上文所述的方式，根据各子块的尺寸分割比例将所述待传输信息块分为多个子块。当然，图3(a)和图3(b)所示仅为示例，在实际应用中，图3(a)和图3(b)中的对应关系可以用任何方式来表示，例如，也可以利用一个表格来表示图3(a)和图3(b)的各项内容。此外，图3(b)中的TBS分割表也可以不示出子块的尺寸分割比例，而替换为其他参数，例如可以为各子块尺寸的具体比特数。图3(a)和/或图3(b)中的映射关系可以预先分别存储在基站和用户设备两端，也可以由基站通过信令告知用户设备，或者可以由用户设备预先上报给基站，在此不做限制。
在一个实现方式中，可以对各个子块分别利用第一类型调制方式进行调制。其中，第一类型调制方式可以为相对低阶的调制方式，这里的低阶调制和之后的高阶调制为相对概念，并非对调制方式的严格限制。在本示例中，可以针对各个子块分别利用相对低阶的星座图进行映射，针对各个子块的映射方式可以相同或不同。随后，还可以针对调制后的各个子块分别利用签名(例如多址签名(MA signature))进行处理，并将处理后的发送数据进行其他处理(如果有的话)之后组合为单个数据序列并发送出去。其中，所述签名可以包括指示针对相应子块设置的功率、扩频序列、扰码序列、交织图案等中的至少一种的信息，或者可以是特定于相应子块的其他信息，在此不做限制。图4示出根据本发明这一示例的对各个子块分别利用第一类型调制方式进行调制的示意图。如图4所示，在对待传输信息块进行分块，得到子块1～子块L之后，可以对各个子块分别利用第一类型调制方式进行调制，并针对调制后的各个子块分别利用多址签名(MA signature)进行处理，然后将处理后的字块组合为单个数据序列，将其作为发送数据进行发送。在一个示例中，用户设备可以在将待传输信息块划分为多个子块之后，且在对各个子块分别利用第一类型调制方式之前，对各个子块进行信道编码。可选地，可以对各个子块分别利用前向纠错码(FEC)进行编码，例如可以对各个子块通过附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)的方式进行编码，然后再对编码后的子块分别利用第一类型调制方式 进行调制。在另一个示例中，可以在将待传输信息块划分为多个子块之前，对待传输信息块进行例如前向纠错码(FEC)的信道编码。可选地，可以对待传输信息块通过附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)的方式进行编码，然后再对编码后的待传输信息块进行子块划分并分别利用第一类型调制方式进行调制。
在另一个实现方式中，还可以将所述各个子块转换为单个数据序列，并对所述单个数据序列利用第二类型调制方式进行调制。具体地，可以将各个子块中的比特通过并串转换来转换为单个数据序列，该单个数据序列中的比特可以根据各个子块的尺寸分割比例而来源于相应的字块。例如，当第一子块的尺寸为第二子块的2倍时，可以按照例如2:1的方式分别提取第一子块和第二子块的比特，构成该单个数据序列的各比特：即，可以提取第一子块的2个比特，再提取第二子块的1个比特，构成该单个数据序列的3个比特，然后还可以用类似的方式，继续提取第一子块的后续2个比特以及第二子块的后续1个比特，以构成该单个数据序列的后续3个比特，以此类推。在将各个子块转换为单个数据序列之后，可以利用第二类型调制方式进行调制。其中，第二类型调制方式可以为相对高阶的调制方式，这里的高阶调制也为相对概念，并非对调制方式的严格限制。在本示例中，可以针对单个数据序列利用相对高阶的星座图进行映射，随后，还可以在调制后利用签名(例如MA签名(signature))进行处理，并将处理后的发送数据发送出去。例如，MA签名可以包括功率、扩频序列、扰码序列、交织图案等中的至少一种信息，当然，MA签名也可以不包括上述信息，在此不做限制。图5示出根据本发明这一示例的对转换后的单个数据序列利用第二类型调制方式进行调制的示意图。如图5所示，在对待传输信息块进行分块，得到子块1～子块L之后，可以对各个子块进行并串转换，合成为单个数据序列，并对此数据序列利用第二类型调制方式进行调制。随后，还可以针对调制后的结果利用多址签名(MA signature)进行处理，并将其作为发送数据进行发送。在一个示例中，用户设备可以在将待传输信息块划分为多个子块之后，且在将各个子块转换为单个数据序列并利用第二类型调制方式进行调制之前，对各个子块进行信道编码。可选地，可以对各个子块分别利用前向纠错码(FEC)进行编码，例如可以对各个子块通过附加传输附加比特(例如循环冗余校验 (CRC)比特或其他类型的附加比特)的方式进行编码，然后再将编码后的子块转换为单个数据序列并利用第二类型调制方式进行调制。在另一个示例中，可以在将待传输信息块划分为多个子块之前，对待传输信息块进行例如前向纠错码(FEC)的信道编码。可选地，可以对待传输信息块通过附加传输附加比特(例如循环冗余校验(CRC)比特或其他类型的附加比特)的方式进行编码，然后再对编码后的待传输信息块进行子块划分和数据序列的转换，以利用第二类型调制方式进行调制。
可选地，所述调制和编码方案索引值对应的参数包括所述星座图映射信息；所述发送数据通过对所述单个比特序列利用所述星座图映射信息进行映射而产生。
在一个示例中，第二类型调制方式中所采用的相对高阶的星座图可以是例如8QAM、16QAM、64QAM、128QAM等现有的星座图之一。此时，所述星座图映射信息可以包括初始星座图的信息，使得采用该初始星座图进行映射。此时，可以将所述单个数据序列划分为多个子信道，并利用初始星座图对所述单个数据序列的不同的子信道进行映射。在这种情况下，星座图映射信息还可以包括单个数据序列分别对应不同子信道的比特数，或者单个数据序列中的每个比特分别对应不同子信道的序号。例如，当采用16QAM星座图对包含4比特一组的数据序列进行映射时，可以定义两个子信道，一个子信道具有1个比特，另一个子信道具有3个比特，则星座图映射信息可以表示为：(16Q，1，3)，其分别表示16QAM星座图，一个比特组中的1个比特为第一子信道，3个比特为第二子信道。或者，星座图映射信息可以表示为(16Q，1，2，2，2)，其分别表示16QAM星座图，一个比特组中的第1比特为第一子信道，第2到4比特为第二子信道。此时，由于第二子信道比第一子信道具有的比特数多，第二子信道比第一子信道具有更大的容量，从而在传输相同数量的信息时有更高的可靠性。因此，可将具有较高优先级的数据映射到第二子信道，并将具有较低优先级的数据映射到第一子信道。每个子信道可传输独立的编码码字。
可替换地，第二类型调制方式中所采用的相对高阶的星座图可以是根据星座图映射信息生成的合成星座图。在一个示例中，所述星座图映射信息可以包括一个或多个初始星座图的信息和/或所述初始星座图对应的调整因子， 其中调整因子可以包括所述初始星座图对应的功率比例和/或旋转角度。从而，对所述单个数据序列利用第二类型调制方式进行调制可以包括：利用所述初始星座图的信息、所述初始星座图对应的功率比例和/或旋转角度，生成合成星座图，利用所述合成星座图对所述单个数据序列进行映射。在上述示例中，所述初始星座图的信息可以是表示例如BPSK、QPSK、16QAM、64QAM、128QAM等星座图中的一个或多个的信息，此外，所述初始星座图的信息还可以表示应用其指示的星座图的比特的信息。例如，可以用b 1,b 2,b 3,b 4等表示各个比特，进一步地，可以用B(b 1)、Q(b 1,b 2)或16Q(b 1,b 2,b 3,b 4)作为所述初始星座图的信息，其中B(b 1)表示用于b 1的BPSK，Q(b 1,b 2)可以表示用于b 1,b 2的QPSK，16Q(b 1,b 2,b 3,b 4)可以表示用于b 1,b 2,b 3,b 4的16QAM等。当然，也可以省略比特的表示，仅利用B表示BPSK，Q表示QPSK，16Q/M表示16QAM。以存在两个初始星座图的情况为例，与这两个初始星座图对应的功率比例可以分别为a 1和a 2，

上述功率比例和/或旋转角度可以由基站根据当前的信道反馈状况予以指示，并通过信令通知给用户设备，也可以由用户设备自行决定，在此不做限制。可选地，当单个数据序列中包含2个比特为一组的多个比特时，假设初始星座图的信息为(B,B,a 1,a 2,

如在图6-8所示的合成星座图中，可通过调整功率因子a 1和a 2的取值来调整各个星座点之间的距离，从而获取 不同子信道对应的不同的可靠性，以实现速率分割，避免由于信道条件或信道反馈方式导致的信道传输性能和容量的下降。
在一个示例中，所述星座图映射信息可以来自前述的调制和编码方案索引对应的参数。具体地，指示信息可以通过指示调制和编码方案表中的调制和编码方案索引和/或所述调制和编码方案索引对应的参数，以指示相应的调制和编码方案表中所包含的星座图映射信息。
在另一个示例中，可以将所述星座图映射信息构建为一个或多个星座图映射信息表，所述星座图映射信息表中可以包含有初始星座图信息、初始星座图对应的功率比例和/或旋转角度等信息。从而，所述指示信息可以是用于指示星座图映射信息表中的星座图映射信息的指示信息，例如，所述指示信息可以通过所述星座图映射信息表中的索引来指示星座图映射信息中的初始星座图信息、初始星座图对应的功率比例和/或旋转角度。可选地，所述星座图映射信息表中可以包含有初始星座图对应的功率比例和/或旋转角度的信息，而所述指示信息可以通过所述星座图映射信息表中的索引来指示星座图映射信息中的初始星座图对应的功率比例和/或旋转角度。在这一示例中，初始星座图信息则可以通过RRC等信令另行指示。图9示出根据本发明一个实施例的星座图映射信息表。图9所示的星座图映射信息表包括了初始星座图对应的功率比例和旋转角度。具体地，星座图映射信息表中的功率比例和旋转角度信息可以通过指示信息发送的星座图映射信息索引来确定。例如，指示信息可以通过星座图映射信息表中的索引1来指示a 1和a 2的功率比例为2:1，旋转角度

例如，处理器2010仅图示出一个，但也可以为多个处理器。此外，可以通过一个处理器来执行处理，也可以通过一个以上的处理器同时、依次、或采用其它方法来执行处理。另外，处理器2010可以通过一个以上的芯片来安装。
用户设备1800和基站1900中的各功能例如通过如下方式实现：通过将规定的软件(程序)读入到处理器2010、内存2020等硬件上，从而使处理器2010进行运算，对由通信装置2040进行的通信进行控制，并对内存2020和存储器2030中的数据的读出和/或写入进行控制。

另外，关于本说明书中说明的用语和/或对本说明书进行理解所需的用语，可以与具有相同或类似含义的用语进行互换。例如，信道和/或符号也可以为信号(信令)。此外，信号也可以为消息。参考信号也可以简称为RS(ReferenceSignal)，根据所适用的标准，也可以称为导频(Pilot)、导频信号等。此外，分量载波(CC，ComponentCarrier)也可以称为小区、频率载波、载波频率等。

进而，时隙在时域中可以由一个或多个符号(正交频分复用(OFDM，OrthogonalFrequencyDivisionMultiplexing)符号、单载波频分多址(SC-FDMA，SingleCarrierFrequencyDivisionMultipleAccess)符号等)构成。此外，时隙也可以是基于参数配置的时间单元。此外，时隙还可以包括多个微时隙。各微时隙在时域中可以由一个或多个符号构成。此外，微时隙也可以称为子时隙。
无线帧、子帧、时隙、微时隙以及符号均表示传输信号时的时间单元。无线帧、子帧、时隙、微时隙以及符号也可以使用各自对应的其它名称。例如，一个子帧可以被称为传输时间间隔(TTI，TransmissionTimeInterval)，多个连续的子帧也可以被称为TTI，一个时隙或一个微时隙也可以被称为TTI。也就是说，子帧和/或TTI可以是现有的LTE中的子帧(1ms)，也可以是短于1ms的期间(例如1～13个符号)，还可以是长于1ms的期间。另外，表示TTI的单元也可以称为时隙、微时隙等而非子帧。
在此，TTI例如是指无线通信中调度的最小时间单元。例如，在LTE系统中，无线基站对各用户终端进行以TTI为单位分配无线资源(在各用户终端中能够使用的频带宽度、发射功率等)的调度。另外，TTI的定义不限于此。
TTI可以是经过信道编码的数据包(传输块)、码块、和/或码字的发送时间单元，也可以是调度、链路适配等的处理单元。另外，在给出TTI时，实际上与传输块、码块、和/或码字映射的时间区间(例如符号数)也可以短于该TTI。
另外，一个时隙或一个微时隙被称为TTI时，一个以上的TTI(即一个以上的时隙或一个以上的微时隙)也可以成为调度的最小时间单元。此外，构成该调度的最小时间单元的时隙数(微时隙数)可以受到控制。
具有1ms时间长度的TTI也可以称为常规TTI(LTE Rel.8-12中的TTI)、标准TTI、长TTI、常规子帧、标准子帧、或长子帧等。短于常规TTI的TTI也可以称为压缩TTI、短TTI、部分TTI(partial或fractional TTI)、压缩子 帧、短子帧、微时隙、或子时隙等。
另外，长TTI(例如常规TTI、子帧等)也可以用具有超过1ms的时间长度的TTI来替换，短TTI(例如压缩TTI等)也可以用具有比长TTI的TTI长度短且1ms以上的TTI长度的TTI来替换。
资源块(RB，ResourceBlock)是时域和频域的资源分配单元，在频域中，可以包括一个或多个连续的副载波(子载波(subcarrier))。此外，RB在时域中可以包括一个或多个符号，也可以为一个时隙、一个微时隙、一个子帧或一个TTI的长度。一个TTI、一个子帧可以分别由一个或多个资源块构成。另外，一个或多个RB也可以称为物理资源块(PRB，PhysicalRB)、子载波组(SCG，Sub-CarrierGroup)、资源单元组(REG，Resource ElementGroup)、PRG对、RB对等。
此外，资源块也可以由一个或多个资源单元(RE，ResourceElement)构成。例如，一个RE可以是一个子载波和一个符号的无线资源区域。
另外，上述的无线帧、子帧、时隙、微时隙以及符号等的结构仅仅为示例。例如，无线帧中包括的子帧数、每个子帧或无线帧的时隙数、时隙内包括的微时隙数、时隙或微时隙中包括的符号和RB的数目、RB中包括的子载波数、以及TTI内的符号数、符号长度、循环前缀(CP，Cyclic Prefix)长度等的结构可以进行各种各样的变更。
此外，本说明书中说明的信息、参数等可以用绝对值来表示，也可以用与规定值的相对值来表示，还可以用对应的其它信息来表示。例如，无线资源可以通过规定的索引来指示。进一步地，使用这些参数的公式等也可以与本说明书中明确公开的不同。
在本说明书中用于参数等的名称在任何方面都并非限定性的。例如，各种各样的信道(物理上行链路控制信道(PUCCH，PhysicalUplink ControlChannel)、物理下行链路控制信道(PDCCH，PhysicalDownlink ControlChannel)等)和信息单元可以通过任何适当的名称来识别，因此为这些各种各样的信道和信息单元所分配的各种各样的名称在任何方面都并非限定性的。
本说明书中说明的信息、信号等可以使用各种各样不同技术中的任意一种来表示。例如，在上述的全部说明中可能提及的数据、命令、指令、信息、 信号、比特、符号、芯片等可以通过电压、电流、电磁波、磁场或磁性粒子、光场或光子、或者它们的任意组合来表示。
此外，信息、信号等可以从上层向下层、和/或从下层向上层输出。信息、信号等可以经由多个网络节点进行输入或输出。
输入或输出的信息、信号等可以保存在特定的场所(例如内存)，也可以通过管理表进行管理。输入或输出的信息、信号等可以被覆盖、更新或补充。输出的信息、信号等可以被删除。输入的信息、信号等可以被发往其它装置。
信息的通知并不限于本说明书中说明的方式/实施方式，也可以通过其它方法进行。例如，信息的通知可以通过物理层信令(例如，下行链路控制信息(DCI，DownlinkControlInformation)、上行链路控制信息(UCI，UplinkControlInformation))、上层信令(例如，无线资源控制(RRC，RadioResourceControl)信令、广播信息(主信息块(MIB，MasterInformationBlock)、系统信息块(SIB，SystemInformationBlock)等)、媒体存取控制(MAC，MediumAccessControl)信令)、其它信号或者它们的组合来实施。
另外，物理层信令也可以称为L1/L2(第1层/第2层)控制信息(L1/L2控制信号)、L1控制信息(L1控制信号)等。此外，RRC信令也可以称为RRC消息，例如可以为RRC连接建立(RRC Connection Setup)消息、RRC连接重配置(RRC Connection Reconfiguration)消息等。此外，MAC信令例如可以通过MAC控制单元(MAC CE(Control Element))来通知。
此外，规定信息的通知(例如，“为X”的通知)并不限于显式地进行，也可以隐式地(例如，通过不进行该规定信息的通知，或者通过其它信息的通知)进行。
关于判定，可以通过由1比特表示的值(0或1)来进行，也可以通过由真(true)或假(false)表示的真假值(布尔值)来进行，还可以通过数值的比较(例如与规定值的比较)来进行。
