Description

发送上行控制信息的方法和移动台 技术领域
本发明涉及无线通信领域，并且具体涉及发送上行控制信息的方法和移动台。
背景技术
在通信系统中，在用户终端中对信道的空间特性进行测量，并且将测量结果以信道状态信息(CSI)的形式反馈给无线基站变得越发重要。根据信道状态不同，用户终端在进行CSI反馈时所报告的信道矩阵的秩也可能不同，相应地，进行CSI反馈所需要的比特数也不同。
在LTE系统中，由于输入多输出(MIMO)天线的规模有限，CSI反馈的比特数之间的差异不大，并且不会给接收侧，即基站，造成显著的影响。然而，在5G NR(New Radio)系统中，由于输入多输出(MIMO)天线规模的增加，CSI反馈的比特数之间的差异也随之增加。然而，根据目前的上行控制信息发送方法，5G NR系统中的基站不能确定包括CSI反馈的上行控制信息中所包含的比特数。

具体实施方式
下面将参照附图来描述根据本发明实施例发送上行控制信息的方法和 移动台。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。此外，这里所述的UE可以包括各种类型的用户终端，例如移动终端(或称为移动台)或者固定终端，然而，为方便起见，在下文中有时候可互换地使用UE和移动台。
在根据本发明的实施例中，上行控制信息可仅包括信道状态信息(CSI)。可替换地，在根据本发明的实施例中，除了信道状态信息(CSI)以外，上行控制信息还可包括HARQ反馈信息等其他控制信息。
以下，参照图1描述根据本发明一个实施例的发送上行控制信息的方法。图1示出了发送上行控制信息的方法100的流程图。
如图1所示，在步骤S101中，对初始控制信息添加填充比特，以生成上行控制信息。在此，初始控制信息可以是要在一个时隙中发送的上行控制信息的初始控制信息。此外，在步骤S101中的初始控制信息可包括对于不同信道矩阵的秩具有相同比特位数的第一信息和对于不同信道矩阵的秩具有相同或不同比特位数的第二信息。例如，第一信息可包括秩指示(RI)和/或CSI-RS资源指示(CRI)等，并且第二信息包括信道质量指示(CQI)和/或预编码矩阵指示(PMI)等。
图2示出了根据本发明的一个实施例的初始控制信息中包括的信道状态信息(CSI)的示意图。在图2所示的示例中，当信道矩阵的RANK(秩)为1时，对应的CSI为CSI 210；当RANK为2时，对应的CSI为CSI 220；当RANK为3或4时，对应的CSI为CSI 230；当RANK为5至8中的任意一个时，对应的CSI为CSI 240。如图2所示，CSI 210至240均包括RI、CQI和PMI。对于RANK 1至8中的任意一个，RI均具有相同的比特数，即，3比特。另一方面，当RANK取值不同时，CQI和PMI可具有不同的比特数。例如，当RANK为1时，PMI具有10个比特。当RANK为2时，PMI具有11个比特。又例如，当RANK为3或4时，CQI具有4个比特。当RANK为5至8时，CQI具有7个比特。
在图2所示的示例中，对应于不同RANK，CSI所包含的总比特数可能不同。具体地，CSI 210-240可分别具有17比特、18比特、17比特和19比特。在此情况下，包含CSI的上行控制信息的比特数也随着RANK的取值 不同而发生改变。
返回图1，在步骤S101中，可通过对初始控制信息添加填充比特，生成具有预定比特数量的上行控制信息。例如，可预先确定上行控制信息应具有X比特。可对初始控制信息添加填充比特，使得不论RANK的取值如何，上行控制信息均为X比特。
图3是示出了根据本发明的一个实施例，对图2中所示的初始控制信息添加填充比特的示意图。如图3所示，假设当RANK为5至8时，需要添加n个比特以便于上行控制信息达到X比特，则当RANK为1时，需要添加n+2个比特以便于上行控制信息达到X比特；当RANK为2时，需要添加n+1个比特以便于上行控制信息达到X比特；当RANK为3或4时，需要添加n+2个比特以便于上行控制信息达到X比特，其中X为大于0的整数，n为大于或等于0的整数。
在图3所示的示例中，填充比特作为一个整体被添加到上行控制信息中。可替换地，根据本发明的另一示例，初始控制信息中的第一信息和第二信息中的每个包括一个或多个分段，在步骤S101中，可对所述一个或多个分段中的至少部分分段分别添加填充比特。例如，第一信息和第二信息可包括对应于如RI、PMI、CQI等不同参数的各个分段。可对于这些分段中的一个或多个，分别添加填充比特。
图4是示出了根据本发明的另一实施例，对图2中所示的初始控制信息添加填充比特的示意图。图2中所示的初始控制信息可包括RI分段、PMI分段、CQI分段。可对RI分段、PMI分段、CQI分段都进行比特填充。如图4所示，可对RI分段添加填充a比特，对PMI分段填充b比特、并且对CQI分段添加填充c比特。可替换地，可仅对一部分分段进行比特填充。例如，在图4所示的示例中，对对PMI分段填充b比特、并且对CQI分段添加填充c比特，而不对RI分段添加填充a比特(如图4中的虚线框所示)。
此外，根据本发明的另一示例，除了CSI信息以外，初始控制信息还可包括例如混合自动重传(HARQ)信息等的其他信息。在此情况下，可对于CSI信息和HARQ信息分别添加填充比特。这里，CSI信息可以是对RI、PMI、CQI等多个参数进行了联合编码的比特序列，也可以是其中分别包括对应于各个参数的分段的比特序列。
在根据本发明的示例中，在步骤S101中添加的填充比特用于校验所述上行控制信息。例如，填充比特可用于上行控制信息的循环冗余校验(CRC)。在此情况下，基站可对UE发送的上行控制信息中的CRC进行盲检。又例如，填充比特可用于上行控制信息的奇偶校验。
例如，如上所述，填充比特可作为一个整体被添加到上行控制信息中。该整体被添加到上行控制信息中的填充比特可用于整个上行控制信息的循环冗余校验。又例如，如上所述，还可对初始控制信息中的一个或多个分段中的至少部分分段分别添加填充比特，被添加的填充比特可用于该分段的循环冗余校验。此外，在对初始控制信息中的一个或多个分段中的至少部分分段分别添加填充比特的情况下，还可添加填充比特以用于整个上行控制信息的循环冗余校验。
此外，根据本发明另一示例，在步骤S101中添加的填充比特可指示初始控制信息中第一信息的至少一部分。例如，可使用第一信息中的秩指示(RI)或秩指示(RI)的一部分作为填充比特。
此外，根据本发明的一个示例，可在对初始控制信息进行信道编码之前进行比特填充。具体地，在步骤S101中，可对初始控制信息添加填充比特，以生成填充比特序列，并且对所述填充比特序列进行信道编码，以生成上行控制信息。可替换地，也可在对初始控制信息进行信道编码时进行比特填充。
在步骤S102中发送生成的上行控制信息。例如，可在物理上行控制信道(PUCCH)或物理上行共享信道(PUSCH)等上行信道上发送所生成的上行控制信息。此外，可在一个时隙中发送所生成的上行控制信息。
在图1所示的发送上行控制信息的方法中，通过对初始控制信息添加填充比特，上行控制信息可具有特定的比特数。从而即使不向基站通知上行控制信息的长度，基站也能够根据确定的该特定比特数来确定上行控制信息的长度。
根据本发明的另一实施例，可通过长度指示信息来向基站通知上行控制信息的长度，以便于基站确定上行控制信息的长度。以下，参照图5描述根据本发明另一实施例的发送上行控制信息的方法。图5示出了发送上行控制信息的方法500的流程图。
如图5所示，在步骤S501中，发送指示上行控制信息的长度的长度指 示信息，其中所述上行控制信息包括对于不同信道矩阵的秩具有相同比特位数的第一信息和对于不同信道矩阵的秩具有相同或不同比特位数的第二信息。在此，初始控制信息可以是要在一个时隙中发送的上行控制信息的初始控制信息。
根据本发明的一个示例，可将解调参考信号(DMRS)中的部分信息作为长度指示信息。例如，可使用DMRS的扰码序列作为长度指示信息，以指示上行控制信息的长度。
然后在步骤S502中，在一个时隙中发送长度指示信息指示其长度的上行控制信息。例如，可在物理上行控制信道(PUCCH)或物理上行共享信道(PUSCH)等上行信道上发送所生成的上行控制信息。从而，基站可通过长度指示信息来确定在一子帧中接收到的上行控制信息的长度，并且可不需要添加填充比特。
此外，根据本发明的另一实施例，基站可向移动台通知关于信道矩阵的秩的信息，在此情况下，基站可根据向移动台通知的信息来预期移动台将返回的上行控制信息的长度，而不需要通过长度指示信息向基站进行通知。以下，参照图6描述根据本发明另一实施例的发送上行控制信息的方法。图6示出了发送上行控制信息的方法600的流程图。
如图6所示，在步骤S601中，根据接收到的指示信息确定信道矩阵的秩。根据本发明的一个示例，可根据基站发送的高层信令来确定所支持的空间的层数，并且从而确定信道矩阵的秩。
在步骤S602中，可根据所确定的信道矩阵的秩对用于多个信道矩阵的秩的初始控制信息进行联合编码，以生成上行控制信息，其中每个信道矩阵的秩的初始控制信息包括对于不同信道矩阵的秩具有相同比特位数的第一信息和对于不同信道矩阵的秩具有相同或不同比特位数的第二信息。
例如，当在步骤S601中确定信道矩阵的秩为RANK 1-2时，在步骤S602中，可对RANK 1所对应的初始控制信息和RANK 2所对应的初始控制信息进行联合编码，其中RANK 1所对应的初始控制信息和RANK 2所对应的初始控制信息中的每个都可包括对于不同信道矩阵的秩具有相同比特位数的第一信息(例如，RI)和对于不同信道矩阵的秩具有相同或不同比特位数的第二信息(例如，PMI或CQI)。又例如，当在步骤S601中确定信道矩阵的 秩为RANK 1-8时，在步骤S602中，可对RANK 1-8分别对应的初始控制信息进行联合编码。
图7是示出了根据本发明的一个实施例，对初始控制信息进行联合编码的示意图。如图7所示，当对RANK 1-2分别对应的初始控制信息进行联合编码时，上行控制信息可具有49151个状态，移动台需要使用16个比特来指示特定的上行控制信息的状态。因此，当基站可向移动台通知关于信道矩阵的秩为RANK 1-2的信息时，可预期上行控制信息的长度的为16比特。当对RANK 1-4分别对应的初始控制信息进行联合编码时，上行控制信息可具有81919个状态，移动台需要使用17个比特来指示特定的上行控制信息的状态。因此，当基站可向移动台通知关于信道矩阵的秩为RANK 1-4的信息时，可预期上行控制信息的长度的为17比特。当对RANK 1-8分别对应的初始控制信息进行联合编码时，上行控制信息可具有344063个状态，移动台需要使用19个比特来指示特定的上行控制信息的状态。因此，当基站可向移动台通知关于信道矩阵的秩为RANK 1-8的信息时，可预期上行控制信息的长度的为19比特。
为了减少用于发送控制信息的比特数，根据本发明的一个示例，可对通信系统中所支持的码本进行下采样。也就是说，以减少上行控制信息中需要表示的码本的数量。优选地，可在2＾n和2＾(n+1)之间设置预定阈值，当上行控制信息所需的表示的状态数量位于2＾n和2＾(n+1)之间，且小于预定阈值时，可对码本进行下采样以减少上行控制信息中需要表示的码本的数量，从而使用较少的比特数来发送上行控制信息。
返回图6，然后，在步骤S603中，发送上行控制信息。例如，可在物理上行控制信道(PUCCH)或物理上行共享信道(PUSCH)等上行信道上发送所生成的上行控制信息。此外，可在一个时隙中发送所生成的上行控制信息。
以上在结合图1-7描述的示例中，可通过填充比特、发送长度指示信息、或根据接收到的指示信息确定信道矩阵的秩等方式来确定上行控制信息的长度。可替换地，为了减少需要发送的控制信令，移动台或基站也不进行上述操作，而直接发送上行控制信息。在此情况下，基站可对于移动台发送的上行控制信息进行盲解码，以确定其长度。
此外，对于不同情况的上行控制信息的发送周期可能不同。例如，在某些情况下，移动台可需要以5ms为周期发送上行控制信息。而在其他情况下，移动台可需要以20ms为周期发送上行控制信息。在此情况下如果只配置一组上行控制信息资源(也可称为“资源组”)，可能造成不必要的上行控制信息发送。因此，根据本发明的另一示例，可配置多组资源以分别发送上行控制信息。
以下，参照图8描述根据本发明另一实施例的发送上行控制信息的方法。图8示出了发送上行控制信息的方法800的流程图。如图8所示，在步骤S801中，以第一时间间隔，使用第一资源(也可以称为“第一资源组”)以发送第一上行控制信息，并且在步骤S802中，独立于所述第一上行控制信息，以第二时间间隔，使用第二资源(也可以称为“第二资源组”)以发送第二上行控制信息。根据本发明的一个示例，第一上行控制信息和所述第二上行控制信息中的至少一个包括对于不同信道矩阵的秩具有相同比特位数的第一信息和对于不同信道矩阵的秩具有相同或不同比特位数的第二信息。例如，第一上行控制信息可以包括对于不同信道矩阵的秩具有相同比特位数的第一信息，第二上行控制信息可以包括对于不同信道矩阵的秩具有相同比特位数的第一信息、以及对于不同信道矩阵的秩具有相同或不同比特位数的第二信息。又例如，第一上行控制信息和第一上行控制信息都可包括对于不同信道矩阵的秩具有相同比特位数的第一信息、以及对于不同信道矩阵的秩具有相同或不同比特位数的第二信息。
此外，例如，可在一个时隙中配置第一资源和第二资源。图9是示出了根据本发明的一个实施例所配置的第一资源和第二资源的示意图。如图9所示，第一资源901和第二资源902可被位置为位于一个时隙所对应的资源池中的不同区域。图9中的一个小方格可以表示一个码元。第一资源901用于发送第一上行控制信息，并且第二资源902用于发送第二上行控制信息。由于第一上行控制信息和第二上行控制信息的发送周期不同，在有些时隙中可能只根据所配置的第一资源发送第一上行控制信息，而在有些时隙中可能既根据所配置的第一资源发送第一上行控制信息，又根据所配置的第二资源发送第二上行控制信息。
当在一个子帧中既发送第一上行控制信息又发送第二上行控制信息时， 可对第一上行控制信息的初始信息和第二上行控制信息的初始信息独立编码，以获得相互独立的第一上行控制信息和第二上行控制信息。另一方面，在当第一上行控制信息和/或第二上行控制信息内部包括多个分段或信息时，可在第一上行控制信息和/或第二上行控制信息内部进行以上结合图1-7描述的填充比特、联合编码等操作。例如，在可对第一上行控制信息的初始控制信息添加填充比特，以生成第一上行控制信息。又例如，可对第二上行控制信息中的各个信息进行联合编码。以上已结合图1-7对填充比特、联合编码等操作进行了详细描述，故在此不再赘述。
根据本发明的一个示例，第一上行控制信息可以是用于宽带(wideband)通信的上行控制信息。第二上行控制信息可以是用于子带(subband)通信的上行控制信息，反之亦然。
下面，参照图10来描述根据本发明一个实施例的移动台。图10示出了根据本发明一个实施例的移动台1000的框图。如图10所示，移动台1000包括填充单元1010和发送单元1020。除了这两个单元以外，移动台1000还可以包括其他部件，然而，由于这些部件与本发明实施例的内容无关，因此在这里省略其图示和描述。此外，由于根据本发明实施例的移动台1000执行的下述操作的具体细节与在上文中参照图1-4描述的细节相同，因此在这里为了避免重复而省略对相同细节的重复描述。
填充单元1010可对初始控制信息添加填充比特，以生成上行控制信息。在此，初始控制信息可以是要在一个时隙中发送的上行控制信息的初始控制信息。此外，初始控制信息可包括对于不同信道矩阵的秩具有相同比特位数的第一信息和对于不同信道矩阵的秩具有相同或不同比特位数的第二信息。例如，第一信息可包括秩指示(RI)和/或CSI-RS资源指示(CRI)等，并且第二信息包括信道质量指示(CQI)和/或预编码矩阵指示(PMI)等。
填充单元1010可通过对初始控制信息添加填充比特，生成具有预定比特数量的上行控制信息。例如，可预先确定上行控制信息应具有X比特。可对初始控制信息添加填充比特，使得不论RANK的取值如何，上行控制信息均为X比特。
根据本发明的一个示例，填充单元1010可将填充的比特作为一个整体添加到上行控制信息中。可替换地，根据本发明的另一示例，初始控制信息 中的第一信息和第二信息中的每个包括一个或多个分段。填充单元1010可对所述一个或多个分段中的至少部分分段分别添加填充比特。例如，第一信息和第二信息可包括对应于如RI、PMI、CQI等不同参数的各个分段。可对于这些分段中的一个或多个，分别添加填充比特。具体地，填充单元1010可对于每个分段都添加填充比特。可替换地，填充单元1010可仅对一部分分段进行比特填充。
此外，根据本发明的另一示例，除了CSI信息以外，初始控制信息还可包括例如混合自动重传(HARQ)信息等的其他信息。在此情况下，填充单元1010可对于CSI信息和HARQ信息分别添加填充比特。这里，CSI信息可以是对RI、PMI、CQI等多个参数进行了联合编码的比特序列，也可以是其中分别包括对应于各个参数的分段的比特序列。
在根据本发明的示例中，填充单元1010添加的填充比特用于校验所述上行控制信息。例如，填充比特可用于上行控制信息的循环冗余校验(CRC)。在此情况下，基站可对UE发送的上行控制信息中的CRC进行盲检。又例如，填充比特可用于上行控制信息的奇偶校验。
例如，如上所述，填充比特可作为一个整体被添加到上行控制信息中。该整体被添加到上行控制信息中的填充比特可用于整个上行控制信息的循环冗余校验。又例如，如上所述，还可对初始控制信息中的一个或多个分段中的至少部分分段分别添加填充比特，被添加的填充比特可用于该分段的循环冗余校验。此外，在对初始控制信息中的一个或多个分段中的至少部分分段分别添加填充比特的情况下，填充单元1010还可添加填充比特以用于整个上行控制信息的循环冗余校验。
此外，根据本发明另一示例，填充单元1010添加的填充比特可指示初始控制信息中第一信息的至少一部分。例如，可使用第一信息中的秩指示(RI)或秩指示(RI)的一部分作为填充比特。
此外，根据本发明的一个示例，可在对初始控制信息进行信道编码之前进行比特填充。具体地，移动台还可包括编码单元(未示出)。填充单元1010可对初始控制信息添加填充比特，以生成填充比特序列。然后，编码单元可对所述填充比特序列进行信道编码，以生成上行控制信息。可替换地，填充单元1010也可在对初始控制信息进行信道编码时进行比特填充。
然后，发送单元1020发送生成的上行控制信息。例如，发送单元1020可在物理上行控制信道(PUCCH)或物理上行共享信道(PUSCH)等上行信道上发送所生成的上行控制信息。此外，发送单元1020可在一个时隙中发送所生成的上行控制信息。
图10所示的移动台通过对初始控制信息添加填充比特，上行控制信息可具有特定的比特数。从而及时不向基站通知上行控制信息的长度，基站也能够根据确定的该特定比特数来确定上行控制信息的长度。
根据本发明的另一实施例，移动台可通过长度指示信息来向基站通知上行控制信息的长度，以便于基站确定上行控制信息的长度。以下，参照图11描述根据本发明另一实施例的移动台。图11示出了根据本发明另一实施例的移动台1100的框图。如图11所示，移动台1100包括发送单元1110。除了发送单元1110以外，移动台1100还可以包括其他部件，然而，由于这些部件与本发明实施例的内容无关，因此在这里省略其图示和描述。此外，由于根据本发明实施例的移动台1100执行的下述操作的具体细节与在上文中参照图5描述的细节相同，因此在这里为了避免重复而省略对相同细节的重复描述。
如图11所示，发送单元1110发送指示上行控制信息的长度的长度指示信息，其中所述上行控制信息包括对于不同信道矩阵的秩具有相同比特位数的第一信息和对于不同信道矩阵的秩具有相同或不同比特位数的第二信息。在此，初始控制信息可以是要在一个时隙中发送的上行控制信息的初始控制信息。
根据本发明的一个示例，可将解调参考信号(DMRS)中的部分信息作为长度指示信息。例如，可使用DMRS的扰码序列作为长度指示信息，以指示上行控制信息的长度。
然后发送单元1110，在一个时隙中发送长度指示信息指示其长度的上行控制信息。例如，可在物理上行控制信道(PUCCH)或物理上行共享信道(PUSCH)等上行信道上发送所生成的上行控制信息。从而，基站可通过长度指示信息来确定在一子帧中接收到的上行控制信息的长度，并且可不需要添加填充比特。
此外，根据本发明的另一实施例，基站可向移动台通知关于信道矩阵的 秩的信息，在此情况下，基站可根据向移动台通知的信息来预期移动台将返回的上行控制信息的长度，而不需要通过长度指示信息向基站进行通知。以下，参照图12描述根据本发明另一实施例的移动台。图12示出了根据本发明另一实施例的移动台1200的框图。如图12所示，移动台1200包括确定单元1210、生成单元1220和发送单元1230。除了图12中所示的三个单元以外，移动台1200还可以包括其他部件，然而，由于这些部件与本发明实施例的内容无关，因此在这里省略其图示和描述。此外，由于根据本发明实施例的移动台1300执行的下述操作的具体细节与在上文中参照图6-7描述的细节相同，因此在这里为了避免重复而省略对相同细节的重复描述。
在图12所示的示例中，确定单元1210根据接收到的指示信息确定信道矩阵的秩。根据本发明的一个示例，可根据基站发送的高层信令来确定所支持的空间的层数，并且从而确定信道矩阵的秩。
生成单元1220可根据所确定的信道矩阵的秩对用于多个信道矩阵的秩的初始控制信息进行联合编码，以生成上行控制信息，其中每个信道矩阵的秩的初始控制信息包括对于不同信道矩阵的秩具有相同比特位数的第一信息和对于不同信道矩阵的秩具有相同或不同比特位数的第二信息。
例如，当确定单元1210确定信道矩阵的秩为RANK 1-2时，生成单元1220可对RANK 1所对应的初始控制信息和RANK 2所对应的初始控制信息进行联合编码，其中RANK 1所对应的初始控制信息和RANK 2所对应的初始控制信息中的每个都可包括对于不同信道矩阵的秩具有相同比特位数的第一信息(例如，RI)和对于不同信道矩阵的秩具有相同或不同比特位数的第二信息(例如，PMI或CQI)。又例如，当确定单元1210确定信道矩阵的秩为RANK 1-8时，生成单元1220可对RANK 1-8分别对应的初始控制信息进行联合编码。
为了减少用于发送控制信息的比特数，根据本发明的一个示例，可对通信系统中所支持的码本进行下采样。也就是说，以减少上行控制信息中需要表示的码本的数量。优选地，可在2＾n和2＾(n+1)之间设置预定阈值，当上行控制信息所需的表示的状态数量位于2＾n和2＾(n+1)之间，且小于预定阈值时，移动台中的采样单元可对码本进行下采样以减少上行控制信息中需要表示的码本的数量，从而使用较少的比特数来发送上行控制信息。
然后，在发送单元1230可发送上行控制信息。例如，可在物理上行控制信道(PUCCH)或物理上行共享信道(PUSCH)等上行信道上发送所生成的上行控制信息。此外，可在一个时隙中发送所生成的上行控制信息。
以上在结合图10-12描述的示例中，可通过填充比特、发送长度指示信息、或根据接收到的指示信息确定信道矩阵的秩等方式来确定上行控制信息的长度。可替换地，为了减少需要发送的控制信令，移动台或基站也不进行上述操作，而由移动台的发送单元直接发送上行控制信息。在此情况下，基站可对于移动台发送的上行控制信息进行盲解码，以确定其长度。
此外，对于不同情况的上行控制信息的发送周期可能不同。例如，在某些情况下，移动台可需要以5ms为周期发送上行控制信息。而在其他情况下，移动台可需要以20ms为周期发送上行控制信息。在此情况下如果只配置一组上行控制信息资源(也可称为“资源组”)，可能造成不必要的上行控制信息发送。因此，根据本发明的另一示例，可配置多组资源以分别发送上行控制信息。
以下，参照图13描述根据本发明另一实施例的移动台。图13示出了根据本发明另一实施例的移动台1300的框图。如图13所示，移动台1300包括发送单元1310。除了图13中所示的发送单元1310以外，移动台1300还可以包括其他部件，然而，由于这些部件与本发明实施例的内容无关，因此在这里省略其图示和描述。此外，由于根据本发明实施例的移动台1300执行的下述操作的具体细节与在上文中参照图8-9描述的细节相同，因此在这里为了避免重复而省略对相同细节的重复描述。
如图8所示，发送单元1310以第一时间间隔，使用第一资源(也可以称为“第一资源组”)以发送第一上行控制信息，并且发送单元1310，独立于所述第一上行控制信息，以第二时间间隔，使用第二资源(也可以称为“第二资源组”)以发送第二上行控制信息。根据本发明的一个示例，第一上行控制信息和所述第二上行控制信息中的至少一个包括对于不同信道矩阵的秩具有相同比特位数的第一信息和对于不同信道矩阵的秩具有相同或不同比特位数的第二信息。例如，第一上行控制信息可以包括对于不同信道矩阵的秩具有相同比特位数的第一信息，第二上行控制信息可以包括对于不同信道矩阵的秩具有相同比特位数的第一信息、以及对于不同信道矩阵的秩具有 相同或不同比特位数的第二信息。又例如，第一上行控制信息和第一上行控制信息都可包括对于不同信道矩阵的秩具有相同比特位数的第一信息、以及对于不同信道矩阵的秩具有相同或不同比特位数的第二信息。
此外，例如，可在一个时隙中配置第一资源和第二资源。由于第一上行控制信息和第二上行控制信息的发送周期不同，在有些时隙中发送单元1310可能只根据所配置的第一资源发送第一上行控制信息，而在有些时隙中发送单元1310可能既根据所配置的第一资源发送第一上行控制信息，又根据所配置的第二资源发送第二上行控制信息。
移动台还可包括编码单元(未示出)。当发送单元1310在一个子帧中既发送第一上行控制信息又发送第二上行控制信息时，编码单元可对第一上行控制信息的初始信息和第二上行控制信息的初始信息独立编码，以获得相互独立的第一上行控制信息和第二上行控制信息。另一方面，移动台还可包括填充单元。在当第一上行控制信息和/或第二上行控制信息内部包括多个分段或信息时，编码单元和填充单元可在第一上行控制信息和/或第二上行控制信息内部进行以上结合图1-7描述的填充比特、联合编码等操作。例如，填充单元在可对第一上行控制信息的初始控制信息添加填充比特，以生成第一上行控制信息。又例如，编码单元可对第二上行控制信息中的各个信息进行联合编码。以上已结合图1-7对填充比特、联合编码等操作进行了详细描述，故在此不再赘述。
根据本发明的一个示例，第一上行控制信息可以是用于宽带(wideband)通信的上行控制信息。第二上行控制信息可以是用于子带(subband)通信的上行控制信息，反之亦然。
<硬件结构>

例如，处理器1410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1410可以通过一个以上的芯片来安装。
移动台1400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1410、内存1420等硬件上，从而使处理器1410进行运算，对由通信装置1440进行的通信进行控制，并对内存1420和存储器1430中的数据的读出和/或写入进行控制。
处理器1410例如使操作系统进行工作从而对计算机整体进行控制。处理器1410可以由包括与周边装置的接口、控制装置、运算装置、寄存器等的中央处理器(CPU，Central Processing Unit)构成。例如，上述的填充单元1010、确定单元1210、生成单元1220、编码单元等可以通过处理器1410实现。
此外，处理器1410将程序(程序代码)、软件模块、数据等从存储器1430和/或通信装置1440读出到内存1420，并根据它们执行各种处理。作为程序，可以采用使计算机执行在上述实施方式中说明的动作中的至少一部分的程序。

输入装置1450是接受来自外部的输入的输入设备(例如，键盘、鼠标、麦克风、开关、按钮、传感器等)。输出装置1460是实施向外部的输出的输出设备(例如，显示器、扬声器、发光二极管(LED，Light Emitting Diode)灯等)。另外，输入装置1450和输出装置1460也可以为一体的结构(例如触控面板)。
此外，处理器1410、内存1420等各装置通过用于对信息进行通信的总线1470连接。总线1470可以由单一的总线构成，也可以由装置间不同的总线构成。
此外，移动台1400可以包括微处理器、数字信号处理器(DSP，Digital Signal Processor)、专用集成电路(ASIC，Application Specific Integrated Circuit)、可编程逻辑器件(PLD，Programmable Logic Device)、现场可编程门阵列(FPGA，Field Programmable Gate Array)等硬件，可以通过该硬件来实现各功能块的部分或全部。例如，处理器1410可以通过这些硬件中的至少一个来安装。
(变形例)
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(Reference Signal)，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，Component Carrier)也可以称为小区、频率载波、载波频率等。
此外，无线帧在时域中可以由一个或多个期间(帧)构成。构成无线帧 的该一个或多个期间(帧)中的每一个也可以称为子帧。进而，子帧在时域中可以由一个或多个时隙构成。子帧可以是不依赖于参数配置(numerology)的固定的时间长度(例如1ms)。
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，Orthogonal Frequency Division Multiplexing)符号、单载波频分多址(SC-FDMA，Single Carrier Frequency Division Multiple Access)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，Transmission Time Interval)，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，Resource Block)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，Physical RB)、子载波组(SCG，Sub-Carrier Group)、资源单元组(REG，Resource Element Group)、PRG对、RB对等。
此外，资源块也可以由一个或多个资源单元(RE，Resource Element)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。

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，Downlink Control Information)、上行链路控制信息(UCI，Uplink Control Information))、上层信令(例如，无线资源控制(RRC，Radio Resource Control)信令、广播信息(主信息块(MIB，Master Information Block)、系统信息块(SIB，System Information Block)等)、媒体存取控制(MAC，Medium Access Control)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。
软件无论被称为软件、固件、中间件、微代码、硬件描述语言，还是以其它名称来称呼，都应宽泛地解释为是指命令、命令集、代码、代码段、程序代码、程序、子程序、软件模块、应用程序、软件应用程序、软件包、例程、子例程、对象、可执行文件、执行线程、步骤、功能等。
此外，软件、命令、信息等可以经由传输介质被发送或接收。例如，当使用有线技术(同轴电缆、光缆、双绞线、数字用户线路(DSL，Digital Subscriber Line)等)和/或无线技术(红外线、微波等)从网站、服务器、或其它远程资源发送软件时，这些有线技术和/或无线技术包括在传输介质的定义内。

在本说明书中，设为通过无线基站进行的特定动作根据情况有时也通过其上级节点(upper node)来进行。显然，在具有无线基站的由一个或多个网络节点(network nodes)构成的网络中，为了与终端间的通信而进行的各种各样的动作可以通过无线基站、除无线基站之外的一个以上的网络节点(可以考虑例如移动管理实体(MME，Mobility Management Entity)、服务网关(S-GW，Serving-Gateway)等，但不限于此)、或者它们的组合来进行。

本说明书中使用的“根据”这样的记载，只要未在其它段落中明确记载，则并不意味着“仅根据”。换言之，“根据”这样的记载是指“仅根据”和“至少根据”这两者。
本说明书中使用的对使用“第一”、“第二”等名称的单元的任何参照，均非全面限定这些单元的数量或顺序。这些名称可以作为区别两个以上单元 的便利方法而在本说明书中使用。因此，第一单元和第二单元的参照并不意味着仅可采用两个单元或者第一单元必须以若干形式占先于第二单元。
