Description

应答消息的反馈、接收方法及装置 技术领域
本文涉及但不限于通信领域，具体而言，涉及一种应答消息的反馈、接收方法及装置。
背景技术
根据高级国际移动通信(International Mobile communications-Advanced，简称为IMT-Advanced)的技术需求，高级长期演进(Long Term Evolution Advanced，简称为LTE-A)为了满足下行峰速1Gbps，上行峰速500Mbps的要求，需要提供最大100MHz的传输带宽，但由于这么大带宽的连续频谱的稀缺，LTE-A提出了载波聚合的解决方案。载波聚合(Carrier Aggregation,简称为CA)是将2个或更多的载波单元(Component Carrier,简称为CC)聚合在一起以支持更大的传输带宽(最大为100MHz)。目前载波聚合已经在第三代合作伙伴计划(3rd Generation Partnership Project，简称为3GPP)R10阶段被标准化。
辅助授权接入(License Assisted Access，简称为LAA)作为3GPP Rel-13重要的研究课题，LAA将授权载波与非授权载波通过载波聚合的方式进行工作，其中授权载波作为主小区，为终端提供基本的网络连接以及移动性能力，非授权载波作为辅小区，为终端提供数据信道容量提升，因此LAA载波聚合的基本架构将采用原有的载波聚合模式。于此同时，由于LAA站点信道接入时需要执行先听后讲(Listen Before Talk，简称为LBT)，因此在LAA站点信号发送中将出现部分子帧的情况，如何对该部分子帧中的物理下行共享信道(Physical Downlink Shared Channel，简称为PDSCH)进行下行信道控制信息(Downlink Control Information，简称为DCI)指示以及如何进行HARQ-ACK反馈是LAA标准研究亟需解决的问题。
其中，在混合自动请求重传(Hybrid Automatic Repeat Request，简称为HARQ)方式中，发端发送的码，不仅能够检错，而且还具有一定的纠错能力。接收端译码器收到码字后，首先检验错误情况，如果在码的纠错能力以 内，则自动进行纠错，如果错误很多，超过了码的纠错能力，但能检测错误出来，则接收端通过反馈信道给发端发一个判决信号，要求发端重发信息。在正交频分复用(Orthogonal Frequency Division Multiplex，简称为OFDM)系统中，通过正确/错误应答(Acknowledgement/Negative-acknowledgement，简称为ACK/NACK)控制信令来表示传输正确/错误，以此来判断是否需要重传，所述的ACK和NACK统称为HARQ-ACK应答信息。
在相关技术中，涉及LAA(License Assisted Access)载波聚合的下行HARQ ACK/NACK反馈问题，尤其当LAA基站执行LBT(Listen Before Talk)后需要发送部分子帧，并且该部分子帧的DCI信息指示在下一个子帧发送，因此该工作场景中下行HARQ ACK/NACK反馈有待研究。
针对相关技术中，部分子帧的HARQ的ACK/NACK应答信息反馈问题，目前还没有有效解决方案。

针对上述LAA下行部分子帧ACK/NACK反馈问题，本可选实施例提供了一种LAA下行HARQ ACK/NACK反馈方案。本发明实施例所采用的技术方案主要包括3个部分：1.反馈定时关系，2.反馈方式，3.传输方式，在下述可选实施例中，需要说明的是，上述第一数据所在子帧和其对应调度信息所在子帧可以不限于n+3和n+4相邻子帧场景，也可以包括其他情况，如：间隔1个或多个子帧等。
该方案还可以应用非授权载波独立运营的场景，或者，未来授权载波也支持后调度场景；通过该方法可以解决后调度场景下ACK/NACK反馈问题，提高下行PDSCH传输性能和系统吞吐量。
1.反馈定时关系：
当PDSCH相应的DCI所在子帧晚于所述PDSCH所在子帧时，所述PDSCH的ACK/NACK反馈子帧根据所述DCI所在子帧确定或者根据所述PDSCH所在子帧确定；
n-4部分子帧的PDSCH的DCI信息指示放在n-3子帧，n-3子帧的PDSCH的DCI信息指示放在n-3子帧，因此对于n-4部分子帧PDSCH的ACK/NACK反馈存在2种定时关系，包括：1)图5是根据本发明可选实施例的n-4子帧PDSCH定时关系示意图，如图5所示，n-4子帧PDSCH定时关系；2)图6是根据本发明可选实施例的n-3子帧(e)PDCCH定时关系，如图6所示，n-3子帧(e)PDCCH(EPDCCH(增强型PDCCH\Enhanced-Physical Downlink Control Channel))定时关系。
2.反馈方式：
对于n-4部分子帧和n-3子帧的PDSCH发送，存在2种反馈方式：1)独立方式；2)捆绑(Bundling)方式，其中，上述独立方式相当于上述实施中的该第一数据的ACK/NACK和该第二数据的ACK/NACK一起反馈，而捆绑方式相当于该第一数据的ACK/NACK和该第二数据的ACK/NACK合并后反馈。
图7是根据本发明可选实施例的.部分子帧PDSCH与PDCCH指示关系1，如图7所示，n-4部分子帧的PDSCH与n-3子帧的PDSCH分别使用独立的DCI进行指示。
图8是根据本发明可选实施例的.部分子帧PDSCH与PDCCH指示关系2，如图8所示，n-4部分子帧的PDSCH与n-3子帧的PDSCH分别使用一个新的DCI进行指示。
可以根据反馈容量和后调度载波数量，确定是否进行spatial bundling，然后按照先载波索引后子帧顺序，将待反馈ACK/NACK串联后一起反馈。
在捆绑(Bundling)方式中，包括：
1)在DCI信息中引入DAI(Downlink Assignment Index)，通过DAI信息去指示n-4部分子帧和n-3子帧是否存在两个PDSCH还是一个PDSCH， 这样可以指示终端是否有PDCCH丢失；
2)在DCI信息中不引入DAI，利用资源区分，通过(e)PDCCH对应的资源位置不同，代表当前调度的是一个PDSCH，还是有两个PDSCH，以解决(e)PDCCH丢失问题，比如将PDCCH资源分为2个资源集合，在其中一个资源集合中发送DCI信息则表示有2个PDSCH，在另一个资源集合中发送DCI信息则表示只有1个PDSCH。
3)在DCI信息中不引入DAI，将n-4部分子帧和n-3子帧联合调度，只存在一个PDSCH(在一个子帧上传输或在两个子帧上传输)；或一个(e)PDCCH可以调度一个PDSCH或2个PDSCH；
3.传输方式：
根据载波的配置情况，传输方式可以分为3种：1)PUCCH格式1b信道选择方式(PUCCH Format 1b with channel selection)；2)PUCCH格式3(PUCCH Format 3)；3)新的PUCCH格式(新的PUCCH Format)。
当授权载波和非授权载波数为2时，终端可以通过PUCCH Format 1b with channel selection方式进行上行反馈ACK/NACK信息，n-4部分子帧PDSCH的DCI信息指示可以如图7或如6所示。
传输方式为PUCCH格式1b信道选择的情况下包括：
eNodeB通过n1-PUCCH-AN-CS-List-r10字段给UE配置了2个PUCCH Format 1资源列表，每个列表分别包含4个PUCCH 1资源，分别为a0/a1/a2/a3和b0/b1/b2/b3。终端根据需要回复的ACK/NACK信息查36.213的Table 10.1.2.2.1-3/4/5可知PUCCH Format1资源以及对应比特信息，UE从A个PUCCH资源中选择相应的资源将PUCCH format 1b携带的2比特信息反馈给eNodeB。
当A＝3时，示例(Case)1：
当授权载波和非授权载波数之和为2时，图9是根据本发明可选实施例的下行HARQ-ACK反馈方案示意图，如图9所示，终端在Pcell上n-3子帧有1个TB进行发送；终端在Scell上n-4部分子帧有1个TB发送，n-3子帧有1个TB发送。

  17. 根据权利要求11所述的方法，其中，所述第二节点根据所述第一数据所在子帧确定所述第一数据对应的正确应答ACK或者错误应答NACK反馈子帧包括：
    当所述第一节点聚合两个服务小区时，跨载波使能后，根据调度信息中资源指示信令确定所述调度信息对应ACK或者NACK的对应上行控制信道资源。
  18. 根据权利要求10所述的方法，其中，所述第二节点根据所述调度信息所在子帧确定所述第一数据对应的正确应答ACK或者错误应答NACK反馈子帧包括：
    在所述调度信息所在子帧上不传输本帧调度信息；所述第二节点在根据所述调度信息所在子帧确定ACK或者NACK反馈子帧上不接收所述调度信息所在子帧上的ACK或者NACK信息。
  19. 一种应答消息的反馈装置，位于终端侧，包括：
    接收模块，设置为接收第二节点发送的第一数据和第一数据相应的调度信息；
    第一确定模块，设置为确定所述第一数据对应的正确应答ACK或者错误应答NACK反馈子帧，在所述确定的子帧上反馈所述ACK或者NACK信息， 其中，传输所述第一数据子帧早于传输所述调度信息的子帧；
    第一确定模块是设置为通过如下方式实现确定所述第一数据对应的正确应答ACK或者错误应答NACK反馈子帧：根据所述第一数据所在子帧确定所述第一数据对应的正确应答ACK或者错误应答NACK反馈子帧，或者，根据所述调度信息所在子帧确定所述第一数据对应的正确应答ACK或者错误应答NACK反馈子帧。
  20. 一种应答消息的接收装置，包括：
    发送模块，设置为发送第一节点的第一数据和第一数据相应的调度信息，其中，传输所述第一数据子帧早于传输所述调度信息的子帧；
    第二确定模块，设置为确定所述第一数据对应的正确应答ACK或者错误应答NACK反馈子帧，在所述确定的子帧上接收所述ACK或者NACK信息，其中，确定所述第一数据对应的正确应答ACK或者错误应答NACK反馈子帧包括：根据所述第一数据所在子帧确定所述第一数据对应的正确应答ACK或者错误应答NACK反馈子帧，或者，根据所述调度信息所在子帧确定所述第一数据对应的正确应答ACK或者错误应答NACK反馈子帧。
