Description

反馈数据传输确认的方法、装置以及通信系统 技术领域
本发明涉及通信领域，特别涉及一种反馈数据传输确认方法、装置以及通信系统。
背景技术
第3代合作伙伴计划(3rd Generation Partnership Project，3GPP)正在研究下一代无线通信系统的相关议题来满足新业务的需求，包括支持具有多种时延要求的业务。原有长期演进(Long Term Evolution，LTE)系统的混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)机制中，针对同一个用户设备(User Equipment，UE)的数据传输与对应的确认反馈之间有时间上的一一对应关系。例如，针对每次数据传输，接收端会在4毫秒后反馈该次传输是否已经成功接收，“ACK”表示成功接收，“NACK”表示没有成功接收。
HARQ中数据传输的反馈(ACK/NACK)通常是通过物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)进行指示。目前LTE系统支持最多两个比特的反馈信息。
为了支持不同时延要求的数据传输，支持更加灵活的资源调度，下一代无线通信系统将支持针对同一个UE的多次数据传输在一次反馈中进行确认，即在一次反馈中指示同一个UE的多次数据传输是否成功。每次数据传输对应一个HARQ进程(process)。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现，为了支持对多次数据传输的确认反馈，需要设计新的PUCCH格式，用以支持更多比特的反馈信息，例如支持4或8比特的反馈信息。一次反馈可能对应一次或多次数据传输，例如多达8次的数据传输均在该次反馈中进行是否成功传输的确认。
因此，多比特的反馈信息与多次数据传输的对应关系需要由协议提前确定。一种最直接的对应关系是系统支持的每一个HARQ进程对应于反馈信息中的一个比特，即第i个HARQ进程(process ID)的数据传输的确认由反馈信息中的第i个比特指示。这样，PUCCH需要反馈的比特数目应该与系统支持的HARQ进程总数相同。例如，总共有8个HARQ进程的系统中，至少需要8比特的PUCCH信息进行反馈确认。
然而，PUCCH上信息的传输可靠性与其传输的比特数目有关。传输更多比特的信息必然降低PUCCH的可靠性。为了保证PUCCH上反馈信息的可靠性，要求传输较少的比特信息。例如，允许PUCCH传输的比特个数少于系统支持的HARQ进程总数。此时，传统的PUCCH反馈信息比特与所有的HARQ进程简单的一一映射的方法将失效。
针对上述问题，本发明实施例提供一种反馈数据传输确认的方法、装置以及通信系统，用以支持使用较少的反馈信息比特指示更多的HARQ进程。
根据本发明实施例的第一方面，提供了一种反馈数据传输确认的方法，其中，所述方法包括：

在本申请中，基站是指网络侧的设备，可以被称为传输点、接入点、广播发射机、节点B、演进节点B(eNB)、RRH等，并且可以包括它们的一些或所有功能。在文中将使用术语“网络设备”。每个网络设备对特定的地理区域提供通信覆盖。
在本申请中，终端或设备可以被称为“用户设备”。UE可以是固定的或移动的，并且也可以称为移动台、移动站、接入终端、用户单元、站等。UE可以是蜂窝电话、个人数字助理(PDA)、无线调制解调器、无线通信设备、手持设备、膝上型计算机、无绳电话、汽车等。
本发明实施例提供了一种反馈数据传输确认的方法，在反馈信息中仅指示被调度在当前时刻进行反馈(称为本次反馈)的HARQ进程的数据传输情况。为了方便说明，在本发明实施例中，仅以“网络侧向用户设备侧发送数据，用户设备向网络侧反馈数据传输确认”为例进行说明，但本发明实施例并不以此作为限制，本发明实施例的原理和方案也适用于“用户设备向网络侧发送数据，网络侧向用户设备侧反馈数据传输确认”的场景。
下面结合附图对本发明实施例进行说明。
实施例1
本实施例提供了一种反馈数据传输确认的方法，该方法应用于用户设备侧，图1是该方法的示意图，如图1所示，该方法包括：
步骤101：当用户设备被调度在当前上行传输信道进行数据传输确认的反馈时，所述用户设备对被调度在当前时刻进行数据传输确认的混合自动重传请求(HARQ)进程进行排序；
步骤102：所述用户设备使用反馈信息比特中的连续比特顺序指示排序后的所述被调度的HARQ进程的数据传输是否成功，所述连续比特的数量与所述被调度的HARQ进程的数量相同；
步骤103：所述用户设备将反馈信息通过所述上行传输信道发送给网络侧。
在本实施例中，如前所述，并不是所有的HARQ进程的数据传输都在本次反馈中进行确认，而每次调度多少个HARQ进程的数据传输在同一次反馈中进行确认是由网络侧决定的。网络侧通常会调度较少个数的HARQ进程在同一次反馈中进行确认，例如少于或等于上行传输信道所支持的用于反馈数据传输确认的比特数目。
在本实施例中，假设当前系统支持M个HARQ进程，其中N个HARQ进程的数据传输被调度在本次反馈中进行确认，本次用于反馈的上行传输信道支持L个比特，也即上行传输信道支持L个比特的反馈信息，该L个比特称为反馈信息比特。其中，N≤L，N≤M，L≤M。L，M，N的具体数值是网络设备(例如eNB)和用户设备(例如UE)所共同知晓的。
在本实施例中，当UE被调度在当前上行传输信道中进行数据传输确认的反馈时，其可以将被调度在当前时刻进行数据传输确认的N个HARQ进程进行排序，并使用L个比特中连续N个比特顺序指示该N个HARQ进程的数据是否成功传输。由此，由于在反馈信息中仅指示被调度在本次反馈中需要确认的HARQ进程的数据传输情况，可以使用较少的反馈信息比特指示更多的HARQ进程的数据传输情况，提高了反馈信道的传输可靠性。
在本实施例中，上述连续比特可以是上述反馈信息比特中的前N个连续比特，也可以是上述反馈信息比特中的后N个连续比特，还可以是上述反馈信息比特中任意位置的N个连续比特，如前所述，N为被调度在当前时刻进行数据传输确认的HARQ进程的个数。
在本实施例中，排序后的N个HARQ进程可以分别被命名为：排序后的第i个HARQ进程，i＝1,2,3,…,N，上述连续比特中的第i个比特可以用于指示上述排序后的被调度的HARQ进程中的第i个HARQ进程的数据传输是否成功。例如，通过“1”指示该HARQ进程的数据已经成功接收，通过“0”指示该HARQ进程的数据传输失败。该指示方式只是示意，本实施例并不以此作为限制。
在本实施例中，如果N＜L，也即系统支持的用于进行数据传输确认的反馈信息比特的数量(L)大于被调度在当前时刻进行数据传输确认的HARQ进程的数量(N)，则该L个反馈信息比特中的第N+1，N+2，N+3,…,L个比特不用于指示HARQ进程的数据传输确认，无意义，可以置为1或0。
在本实施例的一个实施方式中，该用户设备可以根据上述被调度的HARQ进程的进程编号对上述被调度的HARQ进程进行升序排序或降序排序。
例如，M＝8，N＝3，L＝4，8个HARQ进程的进程编号分别是0,1,2,3…,7，其中，HARQ进程3，HARQ进程4，HARQ进程6被调度在当前时刻进行确认反馈。则根据本实施方式，如果按照进程编号的升序进行排序，此时这4个反馈信息比特中的三 个连续比特中的第1个比特指示HARQ进程3的传输情况，第2个比特指示HARQ进程4的传输情况，第3个比特指示HARQ进程6的传输情况，第4个比特无意义。
在本实施例的另一个实施方式中，该用户设备可以根据上述被调度的HARQ进程的数据发送时刻对上述被调度的HARQ进程进行升序排序或降序排序。
例如，M＝8，N＝3，L＝4，8个HARQ进程的进程编号分别是0,1,2,3…,7，其中，HARQ进程3在第1个子帧进行数据传输，HARQ进程4在第5个子帧进行数据传输，HARQ进程6在第3个子帧进行数据传输，他们均被调度在当前时刻进行确认反馈。则根据本实施方式，如果按照数据发送时刻的升序进行排序，此时这4个反馈信息比特中的三个连续比特中的第1个比特指示HARQ进程3的传输情况，第2个比特指示HARQ进程6的传输情况，第3个比特指示HARQ进程4的传输情况，第4个比特无意义。
在本实施例的又一个实施方式中，该用户设备可以根据上述被调度的HARQ进程的数据所使用的物理层技术编号(numerology number)对上述被调度的HARQ进程进行升序排序或降序排序。
例如，M＝8，N＝3，L＝4，8个HARQ进程的进程编号分别是0,1,2,3…,7，其中，HARQ进程3使用的numerology ID是4，HARQ进程4使用的numerology ID是0，HARQ进程6使用的numerology ID是2，他们均被调度在当前时刻进行确认反馈。则根据本实施方式，如果按照数据使用的numerology ID升序进行排序，此时这4个反馈信息比特中的三个连续比特中的第1个比特指示HARQ进程4的传输情况，第2个比特指示HARQ进程6的传输情况，第3个比特指示HARQ进程3的传输情况，第4个比特无意义。
在本实施方式中，如果有任意两个以上的被调度的HARQ进程的数据所使用的物理层技术编号相同，则该用户设备还可以根据该两个以上的被调度的HARQ进程的进程编号或数据发送时刻对该两个以上的被调度的HARQ进程进行升序排序或降序排序。排序方法与前两个实施方式相同，此处不再赘述。
在本实施例中，当用户设备使用反馈信息比特中的上述连续比特顺序指示了排序后的所述被调度的HARQ进程的数据传输是否成功之后，该用户设备可以将反馈信息通过上述上行传输信道发送给网络侧。
在本实施例中，上行传输信道例如为PUCCH，但本实施例并不以此作为限制， 上行传输信道也可以是其他用于反馈数据传输确认的信道，例如物理上行链路共享信道(PUSCH)等。
在本实施例中，如前所述，如果N＜L，则没有被使用的反馈信息比特无意义，可以置为1或0。
通过本实施例的方法，在反馈信息中仅指示被调度在当前时刻进行反馈的HARQ进程的数据传输情况，可以在支持更多HARQ进程数目的系统中，使用较少的反馈信息比特进行数据传输确认的反馈，进而提高了反馈信道的传输可靠性。
实施例2
本实施例提供了一种反馈数据传输确认的方法，该方法应用于网络侧，其是对应实施例1的方法的网络侧的处理，其中与实施例1相同的内容不再重复说明。
图2是该方法的示意图，如图2所示，该方法包括：
步骤201：网络设备接收用户设备发送的被调度在当前时刻进行数据传输确认的混合自动重传请求(HARQ)进程的反馈信息；
步骤202：所述网络设备对所述被调度在当前时刻进行数据传输确认的HARQ进程(简称为被调度的HARQ进程)进行排序；
步骤203：所述网络设备根据所述反馈信息所指示的排序后的所述被调度的HARQ进程的数据传输情况，确定所述被调度的HARQ进程的数据是否成功传输。
在本实施例中，所述反馈信息通过反馈信息比特中的连续比特顺序指示了所述被调度的HARQ进程的数据传输情况，其中，该连续比特的数量与上述被调度的HARQ进程的数量相同。由此，由于在反馈信息中仅指示被调度在本次反馈中需要确认的HARQ进程的数据传输情况，可以使用较少的反馈信息比特指示更多的HARQ进程的数据传输情况，提高了反馈信道的传输可靠性。
在本实施例中，仍以“当前系统支持M个HARQ进程，其中N个HARQ进程被调度在本次反馈中进行确认，并且，系统支持L个比特的反馈信息用于进行上述数据传输确认的反馈”为例。网络侧在接收到UE反馈的L个比特的反馈信息后，对上述N个被调度的HARQ进程进行排序，根据反馈信息中的第i个比特判断排序后的第i个HARQ进程的数据是否成功传输，这里i的含义与实施例1相同，此处不再赘述。由此，用较少的比特指示了更多的HARQ进程的数据传输情况，提高了反馈信 道的传输可靠性。
在本实施例中，上述反馈信息通过上行传输信道(例如实施例1所述的PUCCH或PUSCH等)发送，本实施例对发送方式不作限制。
在本实施例中，与实施例1中用户设备对被调度的HARQ进程进行排序的方法类似，该网络设备可以根据所述被调度的HARQ进程的进程编号对所述被调度的HARQ进程进行升序排序或降序排序，也可以根据所述被调度的HARQ进程的数据发送时刻对所述被调度的HARQ进程进行升序排序或降序排序，还可以根据所述被调度的HARQ进程的数据所使用的物理层技术编号对所述被调度的HARQ进程进行升序排序或降序排序。如果有任意两个以上的被调度的HARQ进程的数据所使用的物理层技术编号相同，则该网络设备还可以进一步根据所述两个以上的被调度的HARQ进程的进程编号或数据发送时刻对所述两个以上的被调度的HARQ进程进行升序排序或降序排序。
在本实施例中，该网络设备还可以根据对上述被调度的HARQ进程进行排序的排序方法，确定排序后的该被调度的HARQ进程与被调度的HARQ进程的进程编号之间的对应关系。从而可以根据上述反馈信息所指示的排序后的该被调度的HARQ进程的数据传输情况，确定该被调度的HARQ进程的数据是否成功传输。
通过本实施例的方法，在反馈信息中仅指示被调度在当前时刻进行反馈的HARQ进程的数据传输情况，可以在支持更多HARQ进程数目的系统中，使用较少的反馈信息比特进行数据传输确认的反馈，进而提高了反馈信道的传输可靠性。
实施例3
本实施例提供了一种反馈数据传输确认的装置，由于该装置解决问题的原理与实施例1的方法类似，因此其具体的实施可以参考实施例1的方法的实施，内容相同之处不再重复说明。
图3是本实施例的反馈数据传输确认的装置的示意图，如图3所示，该装置300包括：排序单元301、指示单元302和发送单元303。该排序单元301在用户设备被调度在当前上行传输信道进行数据传输确认的反馈时，对被调度在当前时刻进行数据传输确认的混合自动重传请求(HARQ)进程进行排序；该指示单元302使用反馈信息比特中的连续比特顺序指示排序后的所述被调度的HARQ进程的数据传输是否成 功，所述连续比特的数量与所述被调度的HARQ进程的数量相同；该发送单元303将反馈信息通过所述上行传输信道发送给网络侧。
在本实施例的一个实施方式中，该排序单元301根据所述被调度的HARQ进程的进程编号对所述被调度的HARQ进程进行升序排序或降序排序。
在本实施例的另一个实施方式中，该排序单元301根据所述被调度的HARQ进程的数据发送时刻对所述被调度的HARQ进程进行升序排序或降序排序。
在本实施例的又一个实施方式中，该排序单元301根据所述被调度的HARQ进程的数据所使用的物理层技术编号对所述被调度的HARQ进程进行升序排序或降序排序。在该实施方式中，如果有任意两个以上的被调度的HARQ进程的数据所使用的物理层技术编号相同，则该排序单元301还可以根据所述两个以上的被调度的HARQ进程的进程编号或数据发送时刻对所述两个以上的被调度的HARQ进程进行升序排序或降序排序。
在本实施例中，上述连续比特是上述反馈信息比特中的前N个连续比特，或者后N个连续比特，或任意位置的N个连续比特，N为上述被调度的HARQ进程的数量。
在本实施例中，上述连续比特中的第i个比特用于指示上述排序后的被调度的HARQ进程中的第i个HARQ进程的数据传输是否成功，i＝1,2,3,…,N，N为上述被调度的HARQ进程的数量。
在本实施例中，上述上行传输信道例如为物理上行链路控制信道(PUCCH)。
通过本实施例的装置，在反馈信息中仅指示被调度在当前时刻进行反馈的HARQ进程的数据传输情况，可以在支持更多HARQ进程数目的系统中，使用较少的反馈信息比特进行数据传输确认的反馈，进而提高了反馈信道的传输可靠性。
本实施例还提供了一种用户设备，配置有前述的反馈数据传输确认的装置300。

在一个实施方式中，反馈数据传输确认的装置300的功能可以被集成到中央处理器401中。其中，中央处理器401可以被配置为实现实施例1所述的反馈数据传输确 认的方法。
例如，该中央处理器401可以被配置为进行如下控制：当用户设备被调度在当前上行传输信道进行数据传输确认的反馈时，对被调度在当前时刻进行数据传输确认的混合自动重传请求(HARQ)进程进行排序；使用反馈信息比特中的连续比特顺序指示排序后的所述被调度的HARQ进程的数据传输是否成功，所述连续比特的数量与所述被调度的HARQ进程的数量相同；将反馈信息通过所述上行传输信道发送给网络侧。
在另一个实施方式中，反馈数据传输确认的装置300可以与中央处理器401分开配置，例如可以将反馈数据传输确认的装置300配置为与中央处理器401连接的芯片，通过中央处理器401的控制来实现反馈数据传输确认的装置300的功能。
如图4所示，该用户设备400还可以包括：通信模块403、输入单元404、音频处理单元405、显示器406、电源407。值得注意的是，用户设备400也并不是必须要包括图4中所示的所有部件；此外，用户设备400还可以包括图4中没有示出的部件，可以参考现有技术。
