Description

传输反馈信息的方法、终端设备和基站 技术领域
本发明实施例涉及通信领域，并且更具体地，涉及一种传输反馈信息的方法、终端设备和基站。
背景技术
一方面，长期演进(Long Term Evolution，LTE)系统中的物理下行共享信道(Physical Downlink Share Channel，PDSCH)支持混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)功能。终端设备与基站建立通信连接后，接收下行控制信令(Downlink Control Information，DCI)，获取PDSCH对应的调度信息(例如，可以包括物理资源位置及数量、调制编码等级等内容)。终端设备根据调度信息接收PDSCH，并对其中承载的传输块(Transport Block，TB)进行解调、译码。若译码结果为正确，则终端设备可以向基站反馈ACK(Acknowledgement)信息。若译码结果为错误，则终端设备可以向基站反馈NACK(Negative Acknowledgment)信息，以便于基站对该TB进行重复传输。
ACK信息或NACK信息可以通过物理上行共享信道(Physical Uplink Share Channel，PUSCH)或物理上行控制信道(Physical Uplink Control Channel，PUCCH)进行传输。当终端设备在上行子帧中无PUSCH传输时，该子帧内传输的ACK信息或NACK只能通过PUCCH传输。
另一方面，LTE系统为实现带宽扩展可以使用载波聚合(Carrier Aggregation，CA)技术，即将多个LTE载波(Component Carrier，CC)聚合在一起，实现更大的传输带宽。
针对载波聚合技术，现有技术提出了一种授权辅助接入(License Assisted Access，LAA)技术，实现授权载波和非授权载波的聚合。对于LAA系统中的非授权载波，基站完成一个子帧内的数据准备(编码、调制、资源映射等)，但是具体在哪个子帧传输上述数据是不确定的，即基站不能够完全了解任一下行子帧内各载波上的调度情况。因此，基站无法在DCI中设置信息指示终端设备需要反馈的反馈信息(ACK信息或NACK信息)的数量，使得基站与终端设备在传输反馈信息时效率低下。
发明内容
本发明实施例提供一种传输反馈信息的方法、终端设备和基站，可以提高传输反馈信息的效率。

由此，使用确定长度的反馈信息序列，基站在进行接收时不需要对反馈信息序列长度进行盲检测，简化检测算法，提高检测性能。对信息进行补位可以保证基站与终端设备对反馈信息序列中各比特信息的对应关系理解一致。

在第二方面的一种可能的实现方式中，所述方法还包括：
所述基站根据在所述非授权载波上发送的物理下行共享信道PDSCH的数量，确定M的值；或者，
所述基站根据发送PDSCH的所有所述非授权载波的最大的载波编号，确定M的值；或者，

在第一方面至第六方面及相应的实现方式中，L等于1，所述L个第一PUCCH资源为所述非授权载波中载波编号最大的非授权载波对应的第一PUCCH资源。
应理解，L等于1的方案，使得多个非授权载波的对应的反馈信息可以在相同的PUCCH资源上传输，对终端设备的功率要求更低，可以节省资源。
基于上述技术方案，本发明实施例的传输反馈信息的方法、终端设备和基站，终端设备接收基站发送的用于指示PUCCH资源的信令，并在聚合使用的授权载波和非授权载波上接收数据，生成反馈信息后，通过相应的PUCCH资源将反馈信息传输给基站，可以提高传输反馈信息的效率。

下面简要介绍本发明实施例的涉及的相关技术及概念。
载波聚合技术：
随着通信技术的发展，由LTE技术演进出了长期演进技术升级版(LTE-Advanced，LTE-A)技术。在LTE-A的版本10(Release10，R10)系统中，开始使用CA)技术实现带宽扩展，即可以将如图1所示的最多5个LTE载波CC1～CC5聚合在一起，实现最大100MHz的传输带宽。根据终端设备的能力及其传输的数据量，基站可以针对每个终端设备配置其进行聚合传输的载波数量，聚合的载波可以称为成员载波。
对于一个终端设备而言，聚合的多个成员载波包括：(1)主载波(Primary Cell，PCell)，主载波只有一个，终端设备在主载波上进行初始连接建立过程或开始连接重新建立过程，终端设备只在主载波上接收PDCCH的公共搜索空间，且终端设备只在主载波上发送PUCCH。(2)辅载波(Secondary Cell， SCell)，除主载波以外的其他成员载波都是辅载波，终端设备可在辅载波接收DCI、PDSCH，并在辅载波上发送PUSCH。
ACK信息或NACK信息的反馈：
终端设备与基站建立通信连接后，接收DCI，获取PDSCH对应的调度信息(例如，可以包括物理资源位置及数量、调制编码等级等内容)。终端设备根据调度信息接收PDSCH，并对其中承载的TB进行解调、译码。若译码结果为正确，则终端设备可以向基站反馈ACK信息。若译码结果为错误，则终端设备可以向基站反馈NACK信息，以便于基站对该TB进行重复传输。
ACK信息或NACK信息可以通过物理上行共享信道(Physical Uplink Share Channel，PUSCH)或物理上行控制信道(Physical Uplink Control Channel，PUCCH)进行传输。当终端设备在上行子帧中无PUSCH传输时，该子帧内传输的ACK信息或NACK只能通过PUCCH传输。
LAA技术：
目前，无线蜂窝系统中开始考虑通过使用非授权频段(Unlicensed频段，例如2.4GHz、5.8GHz等频段)扩展蜂窝系统的使用频率。其主要技术包括LAA技术。LAA技术的主要特点包括：(1)非授权频段需要与授权频段聚合使用，且非授权频段只能作为辅载波工作。为更好的支持LAA技术，LTE-A版本13(Release13，R13)系统可支持最多32个成员载波进行聚合。(2)非授权频段的使用不仅受限于基站的调度，也受限于非授权频段的负载，即需要经过竞争机制才能够使用。
对于传统载波聚合系统，基站的调度器对某一个子帧内各载波的数据统一调度，因此基站能够完全了解该子帧内各载波上的调度情况。因此，基站可以在DCI中设置某些信息域用于通知终端设备当前子帧内该终端设备需要反馈的ACK信息或NACK信息的总数量，从而提高终端设备与基站之间传输ACK信息或NACK信息的效率。
但是，对于LAA系统中的非授权载波，基站完成一个子帧内的数据准备(编码、调制、资源映射等)，但是具体在哪个子帧传输上述数据是不确定的，即基站不能够完全了解任一下行子帧内各载波上的调度情况。因此，基站无法在DCI中设置信息指示终端设备需要反馈的反馈信息(ACK信息或NACK信息)的数量，使得基站与终端设备在传输反馈信息时效率低下。
应理解，本文所称反馈信息可以包括ACK信息和/或NACK信息。
本发明各实施例中，在LAA系统中，基站可以对某一个子帧内各授权载波的数据统一调度，因此基站能够完全了解该子帧内各授权载波上的调度情况，因而基站可以预先知晓终端设备欲传输的授权载波对应的反馈信息的数量。对于非授权载波，终端设备可以以与基站约定好的方式生成一定数量的反馈信息，因而基站也可以根据约定好的方式获知终端设备欲传输的非授权载波的反馈信息的数量，因而解决基站由于不知终端设备传输的ACK信息或NACK信息的数量，从而造成的传输反馈信息时效率低下的问题。以上即为本发明的思想。
在本发明的一个实施例中，基站和终端设备可以依照协议或者预先设定的规则，约定一种确定非授权载波对应的M比特反馈信息的方式，由此便可以解决在LAA系统中基站无法知道终端设备传输的反馈信息的数量的问题。例如，(1)终端设备可以根据在非授权载波上接收到的PDSCH的数量，确定M的值。基站依照同样的规则可以确定M的值。
具体地，在一个示例中，终端设备根据接在一个下行子帧n上接收到的PDSCH总数量及各非授权载波上的传输模式确定反馈信息的序列的总长度。如图2所示，其中非授权载波配置为单码字传输模式时，一个PDSCH对应1比特反馈信息(ACK信息或NACK信息)；非授权载波配置为双码字传输模式时，一个PDSCH对应2比特反馈信息。终端设备在其使用的8个非授权载波上接收到PDSCH a～c，相应地，确定反馈信息的序列ba,0，bb,0，bb,1，bc,0。
或者，(2)终端设备可以根据接收到PDSCH的所有非授权载波的最大的载波编号，确定M的值。基站依照同样的规则可以确定M的值。
具体地，在一个示例中，终端设备根据接在一个下行子帧n上接收到的PDSCH的所有非授权载波中编号最大的非授权载波及各非授权载波上的传输模式确定反馈信息的序列的总长度M的值，并生成M比特反馈信息。如图3所示，其中X表示占位信息，对于接收到的PDSCH的所有非授权载波中编号最大的非授权载波之前的非授权载波，当其未接收到PDSCH时，不反馈ACK信息或NACK信息，以占位信息X表示。终端设备在其使用的8个非授权载波上接收到PDSCH a～c，相应地确定反馈信息的序列X，ba,0，X，X，X，X，bb,0，bb,1，X，bc,0。即，反馈信息到接收到的PDSCH的编号最大的非授权载波截至，后续的未接收到PDSCH的非授权载波不再以占位信 息X表示。应理解，与前一例子类似，本例子中每一非授权载波对应的反馈信息的比特数与非授权载波的传输模式相对应，此处不再赘述。
或者，(3)终端设备可以根据聚合的非授权载波的总数量，确定M的值。基站依照同样的规则可以确定M的值。
具体地，在一个示例中，终端设备根据聚合的所有非授权载波及各非授权载波上的传输模式确定反馈信息序列的总长度。如图4所示，其中X表示占位信息，对于所有非授权载波，当其未接收到PDSCH时，不反馈ACK信息或NACK信息，以占位信息X表示。终端设备在其使用的8个非授权载波上接收到PDSCH a～c，相应地确定反馈信息的序列X，ba,0，X，X，X，X，bb,0，bb,1，X，bc,0，X，X。应理解，与前两个例子类似，本例子中每一非授权载波对应的反馈信息的比特数与非授权载波的传输模式相对应，此处不再赘述。
此外，除以以上方法确定非授权载波对应的反馈信息的比特数外，如果本发明实施例所应用的系统为时分复用(Time Division Duplexing，TDD)系统时，由于下行子帧的数量与上行子帧的数量有可能是不相等的，则确定非授权载波对应的M比特反馈信息，还可以根据该第一下行子帧集合中的下行子帧的数量，确定M的值。其中，第一下行子帧集合，(例如下行子帧集合S)包括使用第一上行子帧传输反馈信息的所有下行子帧。即，将使用同一上行子帧(例如，第一上行子帧)传输反馈信息的所有下行子帧的反馈信息，集合在一起生成M比特反馈信息的序列一同发送。
上面详细介绍了终端设备与基站按约定确定M，以及终端设备生成M比特反馈信息的具体实现方式。应理解，终端设备与基站按约定确定M，以及终端设备生成M比特反馈信息的方法还可以有其他多种形式，本发明实施例对此不作限定。
下面详细介绍本发明实施例的基站与终端设备通过信令或消息等，交互传输反馈信息的流程。
首先介绍基站对PUCCH资源的配置。基站可以针对每一个非授权载波配置一个PUCCH资源，不同的非授权载波对应的PUCCH资源可以相同也可以不同。
在一个具体的实例中，如图5所示，传输反馈信息的方法100包括：
S110，基站向终端设备发送第一信令。相对应地，对于终端设备而言， 终端设备接收基站发送的第一信令。该第一信令用于指示K个第一PUCCH资源，该K个第一PUCCH资源用于在第一上行子帧传输第一下行子帧集合中该终端设备在非授权载波上接收数据的反馈信息，其中，K为正整数，该第一下行子帧集合包括使用该第一上行子帧传输反馈信息的所有下行子帧，该非授权载波与授权载波聚合使用。
具体而言，基站可通过高层信令以半静态方式配置PUCCH资源，也可以通过下行控制信令以动态方式配置PUCCH资源。基站可以为终端设备使用的每一个非授权载波配置一个PUCCH资源。任意两个非授权载波所配置的PUCCH资源可以相同，也可以不同。当所有非授权载波所配置的PUCCH资源相同时，K等于1。
S120，在该第一下行子帧集合S中，基站在聚合使用的授权载波和/或非授权载波上向终端设备发送数据。相对应地，该终端设备在授权载波和/或非授权载波上接收数据。其中，聚合使用的授权载波和/或非授权载波，是指基站授权终端设备可以在授权载波和非授权载波上同时接收数据。在实际实施的时候，根据数据的分发情况及载波的情况，基站可以在聚合使用的授权载波和非授权载波上均向终端设备发送数据，也可以只在授权载波上向终端设备发送数据，还可以只在非授权载波上向终端设备发送数据，本发明实施例对此不作限定。
在S130中，当基站在非授权载波上发送数据时，终端设备在非授权载波上接收数据，并对于非授权载波接收到的数据确定M比特反馈信息，其中，M为大于或等于0的整数。确定M的方法，以及M比特反馈信息的生成方法，可以依前文的描述，此处不再进行赘述。
在S140中，当基站在授权载波上发送数据时，该终端设备在授权载波上接收数据，并对于授权载波接收到的数据确定N比特反馈信息，其中，N为大于或等于0的整数。
具体地，确定N比特反馈信息，可以包括：根据DCI确定N的值。其中，DCI用于调度授权载波的数据传输。即，终端设备所使用的授权载波是基站通过发送DCI来调度的。因而，基站能够通过终端设备使用授权载波的情况预知终端设备发送反馈信息的情况，基站可以在DCI中设置一个信息域用于携带N的值，或者携带确定N的算法或规则，本发明实施例对此不作限定。终端设备根据DCI的信息域即可确定N的值。
应理解，S130和S140在本发明实施例中不都是必须的，但S130和S140至少会执行一个步骤，具体如S120中的描述相似，此处不再赘述。
对于现有的LAA系统而言，终端设备聚合A(A大于或等于1)个授权载波，B(B大于或等于1)个非授权载波。若M等于0，S150，终端设备可以在第一上行子帧中，在至少一个第二PUCCH资源上传输N比特反馈信息，其中，至少一个第二PUCCH资源可以是根据用于调度该授权载波的数据传输的DCI确定的。优选地，可以在一个第二PUCCH资源上传输N比特反馈信息。
当M大于0时，则可以选取S160和S170两种方案中的一种。
其中，将S160对应的方案简称为独立PUCCH方案。
具体而言，授权载波重用LTE R13载波聚合ACK信息或NACK信息反馈的工作方式。进行DCI设置时，基站只考虑授权载波上的调度情况。终端设备根据DCI确定传输反馈信息的第二PUCCH资源，并使用该第二PUCCH资源传输授权载波对应的反馈信息。相对应地，终端设备在该第一上行子帧，在至少一个第二PUCCH资源上传输该N比特反馈信息，其中，该至少一个第二PUCCH资源是根据用于调度该授权载波的数据传输的下行控制信息DCI确定的。
若终端设备在非授权载波上接收到数据，则在独立的第一PUCCH资源上只传输非授权载波对应的反馈信息。由于终端设备需要同时在多个PUCCH资源上(至少一个第一PUCCH资源和至少一个第二PUCCH资源)发送多个PUCCH，在终端设备发射功率有限制时，则优先保证授权载波对应的PUCCH传输，非授权载波对应的PUCCH功率甚至可降低为0，本发明实施例对此不作限定。
应理解，S160对应的方案可以与现有的授权载波对应的反馈信息的传输方案更好地兼容。由于授权载波的可靠性要求高于非授权载波，该方案可以优先保证授权载波对应的ACK/NACK信息的传输性能不受影响。
将S170对应的方案简称为联合PUCCH方案。
具体而言，终端设备在授权载波和非授权载波上，则使用根据非授权载波确定的第一PUCCH资源传输所有反馈信息(授权载波对应的N比特反馈信息和非授权载波对应的M比特反馈信息)。相对应地，终端设备在该第一上行子帧，在L个第一PUCCH资源上传输该N比特反馈信息。其中，L为 小于或等于K的正整数
应理解，S170对应的方案，授权载波对应的反馈信息和非授权载波的对应的反馈信息可以在相同的PUCCH资源上传输，对终端设备的功率要求更低，可以节省资源。
总而言之，不论是独立PUCCH方案还是联合PUCCH方案，终端设备在该第一上行子帧，在该K个第一PUCCH资源中的L个第一PUCCH资源上传输该M比特反馈信息，其中，L为小于或等于K的正整数。
当M大于0时，优选地一个方案为，L等于1，该L个第一PUCCH资源为该非授权载波中载波编号最大的非授权载波对应的第一PUCCH资源。
具体而言，若终端设备在下行子帧集合S中，同时在多个非授权载波上接收到下行数据，且不同非授权载波对应的第一PUCCH资源不同，终端设备可以根据约定的规则选择一个第一PUCCH资源，作为实际传输所使用的PUCCH资源。优选地，选择所有收到下行数据传输的非授权载波中编号最大的非授权载波对应的PUCCH资源。应理解，本发明实施例中，终端设备也可以使用其他约定规则，例如编号最小的非授权载波对应的PUCCH资源，本发明实施例对此不作限定。
应理解，L等于1的方案，使得多个非授权载波的对应的反馈信息可以在相同的PUCCH资源上传输，对终端设备的功率要求更低，可以节省资源。
此外，在该K个第一PUCCH资源中的L个第一PUCCH资源上传输该M比特反馈信息，可以包括：
当M小于Q时，对该M比特反馈信息进行补位，得到长度为Q比特的信息序列，在该K个第一PUCCH资源中的L个第一PUCCH资源上传输该长度为Q比特的信息序列，其中，Q为正整数，Q是协议约定的或由该基站配置的阈值。
应理解，使用确定长度的反馈信息序列，基站在进行接收时不需要对反馈信息序列长度进行盲检测，简化检测算法，提高检测性能。对信息进行补位可以保证基站与终端设备对反馈信息序列中各比特信息的对应关系理解一致。
在本发明实施例中，在该K个第一PUCCH资源中的L个第一PUCCH资源上传输该M比特反馈信息和该在该L个第一PUCCH资源上传输该N比特反馈信息，可以包括：
将该M比特反馈信息和该N比特反馈信息级联并进行联合编码后，在该L个第一PUCCH资源上进行传输。
具体而言，非授权载波对应的M比特反馈信息和授权载波对应的N比特反馈信息级联的方案可以有多种。
作为一个示例，如图6所示，可以将N比特反馈信息映射在前，M比特反馈信息映射在后，得到级联信息。应理解。反之，也可以将M比特反馈信息映射在前，N比特反馈信息映射在后，得到级联信息。
作为另一个示例，如图7所示，可以将N比特反馈信息与M比特反馈信息交织映射，得到级联信息。交织的方法可以参考现有的交织技术，本文对此不进行赘述。
对应方法100，图8从终端设备的角度，示出了根据本发明一个实施例的传输反馈信息的方法200，方法200包括：
S210，终端设备接收基站发送的第一信令，该第一信令用于指示K个第一物理上行控制信道PUCCH资源，其中，K为正整数；
S220，在第一下行子帧集合中，该终端设备分别在聚合使用的授权载波和非授权载波上接收数据，对于该授权载波确定N比特反馈信息，对于该非授权载波确定M比特反馈信息，其中，M为大于或等于0的整数，N为大于或等于0的整数，并且M和N中至少有一个不为0；
S230，该终端设备判断M的值是否大于0；
S240，当M大于0时，该终端设备在该第一上行子帧中，在该K个第一PUCCH资源中的L个第一PUCCH资源上传输该M比特反馈信息和该N比特反馈信息，或者，该终端设备在第一上行子帧中，在至少一个第二PUCCH资源上传输该N比特反馈信息，在该K个第一PUCCH资源中的L个第一PUCCH资源上传输该M比特反馈信息，其中，L为小于或等于K的正整数，该至少一个第二PUCCH资源是根据用于调度该授权载波的数据传输的下行控制信息DCI确定的；
其中，该第一下行子帧集合包括使用该第一上行子帧传输反馈信息的所有下行子帧。
应理解，本发明实施例中S240的中第一种方案对应方法100的联合PUCCH方案，第二种方案对应方法100的独立PUCCH方案。
其中，优选地，L等于1，该L个第一PUCCH资源为该非授权载波中 载波编号最大的非授权载波对应的第一PUCCH资源。
