Description

应答信息的传输方法、装置及设备 技术领域
本发明实施例涉及通信技术，尤其涉及一种应答信息的传输方法、装置及设备。

长期演进(Long Term Evolution，简称：LTE)系统的时分双工(Time Division Duplex，简称：TDD)制式，即LTE TDD系统支持载波聚合(Carrier Aggregation，简称：CA)技术，可以把多个成员载波或服务小区同时分给一个用户设备(User equipment，简称：UE)以支持更高的数据速率传输。
现有技术中，最多可以给一个UE配置5个载波或服务小区。但是，如果某个载波或服务小区的配置是上下行配置5，就会限制应答信息的传输。例如，对于物理上行控制信道(Physical Uplink Control Channel，简称：PUCCH)格式3的传输模式，其支持的应答信息最大比特数为20，现有技术中，在载波聚合的场景下有一个载波是在某些TDD上下行配置下或该载波在某些参考上下行配置下，最多可以给UE配置两个载波。此外，在某些TDD参考配置下，辅服务小区的所有下行子帧对应的应答信息都在一个或少数几个上行子帧上反馈，导致反馈时延增加且反馈性能下降。

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

图2为本发明应答信息的传输装置实施例二的结构示意图；
图3为本发明应答信息的传输设备实施例一的结构示意图；
图4为本发明应答信息的传输方法实施例一的流程示意图；

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在LTE TDD系统中，收发在同一载波的不同时间完成，即上下行传输在时间上以子帧粒度进行区分。LTE TDD系统中的子帧包括下行子帧、上行子帧和特殊子帧，其中，特殊子帧包括下行导频时隙(Downlink Pilot Time Slot，简称：DwPTS)，保护间隔(Guard Period，简称：GP)和上行导频时隙(Uplink  Pilot Time Slot，简称：UpPTS)，其中，GP主要用于下行到上行的转换时间和传播时延的补偿。特别地，特殊子帧的DwPTS可以传输下行数据，因此，有时也可以把特殊子帧看做下行子帧来处理，比如DwPTS上传输的下行数据需要有相应的应答信息反馈。其中，应答信息的状态包括确认(ACKnowledge，简称：ACK)或不确认(NACKnowledge，简称：NACK)。
LTE TDD系统可以支持7种不同的上下行配置，具体的配置如表1所示。在表1中，D表示下行子帧，S表示特殊子帧，U表示上行子帧，其中，上下行配置0、1、2和6的下行-上行转换周期为5毫秒(ms)，上下行配置3、4和5的下行-上行转换周期为10 ms。
表1 LTE TDD系统不同的上下行配置

另外，TDD CA包括相同上下行配置的CA，比如两个上下行配置1的CA；和，不同上下行配置的CA，比如上下行配置1和配置2的CA。CA包括一个主服务小区和至少一个辅服务小区，且承载HARQ-ACK的PUCCH仅发送在主服务小区上。CA中PUCCH的发送模式包括信道选择模式和PUCCH格式3两种模式。
对于相同上下行配置的CA，主辅服务小区的混合自动重传请求应答信息(Hybrid Automatic Repeat Request Acknowledge，简称：HARQ-ACK)时序关系与单载波时TDD的时序关系相同。对于不同上下行配置的CA，主服务小区的HARQ-ACK时序关系遵循主服务小区自身的上下行配置的HARQ-ACK时序关系，但辅服务小区的HARQ-ACK时序关系遵循参考上下行配置的 HARQ-ACK时序关系，该参考上下行配置可以为主服务小区的上下行配置，也可以为辅服务小区自己的上下行配置，还可以为不同于主辅服务小区的上下行配置。具体的参考上下行配置由主辅服务小区对的上下行配置组合来确定，如表2所示。
表2 基于主辅服务小区对的辅服务小区的HARQ-ACK时序关系
Figure PCTCN2014086854-appb-000002
这里，举例说明上下行配置5下的最多两个载波CA的限制问题，以CA组合(2,5)为例进行说明如下。
表3 主服务小区配置2和辅服务小区配置5进行CA的载波数量限制问题
Figure PCTCN2014086854-appb-000003
假设主服务小区为上下行配置2，辅服务小区为上下行配置5。如表3所示，当只有一个辅服务小区时，根据上述表2可以确定辅服务小区的参考上下行配 置为该辅服务小区自身的上下行配置5。具体的数据调度和HARQ-ACK反馈流程为，假设辅服务小区的子帧8调度了物理下行共享信道(Physical Downlink Shared Channel，简称：PDSCH)，需要在下一个无线帧的子帧2上反馈该PDSCH对应的HARQ-ACK，这个具体的HARQ时序关系可以根据表3中的上行子帧2上包含的数字集合中的数字个数4看出，即当子帧2为HARQ-ACK反馈子帧时，该子帧上反馈的HARQ-ACK对应的承载PDSCH的子帧为n-4，即上一个无线帧的子帧8。辅服务小区对应该子帧上的数字集合的总数为9，辅服务小区上的所有9个下行子帧上传输的PDSCH对应的HARQ-ACK都需要在该上行子帧上反馈。将这个总数定义为M值，此时，该M值＝9。
由于信道选择模式最大支持M值＝4，因此，信道选择模式不支持上下行配置5，CA中PUCCH的发送模式采用PUCCH格式3模式。而PUCCH格式3模式最大支持大小为20比特的HARQ-ACK，若主服务小区为上下行配置2，两个辅服务小区均为上下行配置5时，子帧2上的所有小区各自的M值总和为4+9+9＝22，该总和大于20，因此，PUCCH格式3模式无法支持多于两个上下行配置5的辅服务小区的CA。另外，对于一个辅服务小区为上下行配置5的情况，其HARQ-ACK反馈时序延时很长，比如最长的时序为n-13，即13个子帧的延时；且由于M值为9，导致HARQ-ACK性能下降。特别的，对于上行子帧2上包含的数字集合中的数字顺序不受限制，即任何顺序都可以，只要对应的PDSCH子帧个数和子帧号一致就行。对于其他TDD上下行配置和其他TDD上下行配置下的其他反馈HARQ-ACK的上行子帧都适用，即都不考虑PDSCH子帧顺序问题。
将来网络部署的一个重要场景是主服务小区在宏基站上，且TDD配置为上行子帧多的上下行配置以保证反馈性能和时延，比如上下行配置1或2；而辅服务小区在微基站或微微基站上，且TDD配置为下行子帧多的上下行配置以保证高下行数据速率的传输，即把宏基站的下行业务向微基站卸载，比如配置上下行配置5。鉴于(0/1/2,5)这些CA组合的大量部署和配置，且考虑到上述载波数量限制和反馈时延以及反馈性能的问题，需要新的解决方案来克服，以达到TDD某些上下行配置下可以配置更多载波，且缩短反馈时延并提高反馈性能。
基于上述问题，本发明实施例提供了一种应答信息的传输方法、装置及 设备，应用于LTE TDD系统，可以分别用于基站侧和UE侧，具体的，以下进行详细说明。
图1为本发明应答信息的传输装置实施例一的结构示意图。本发明实施例提供一种应答信息的传输装置，该装置应用于TDD系统，该装置可以集成在例如基站等设备中。如图1所示，该装置包括：发送模块11、确定模块12和接收模块13。
其中，确定模块12用于确定在辅服务小区上向UE发送PDSCH；发送模块11用于在辅服务小区上向UE发送确定模块12确定的PDSCH；确定模块12还用于确定辅服务小区对应的HARQ时序关系，该HARQ时序关系为PDSCH与HARQ-ACK的HARQ时序关系；接收模块13用于根据确定模块12确定的HARQ时序关系，在主服务小区上接收PDSCH所对应的HARQ-ACK。该实施例中，主服务小区为基站为UE配置的TDD主服务小区，辅服务小区为基站为UE配置的N个TDD辅服务小区中的辅服务小区，N为大于或等于1的自然数。

当所述主服务小区的上下行配置为上下行配置1时，所述主服务小区的上行子帧包括子帧2、子帧3、子帧7和子帧8，在所述主服务小区的子帧2上反馈对应于所述子帧2向前偏移7个和/或向前偏移6个子帧后所对应的所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧3反馈对应于所述子帧3向前偏移6个子帧、向前偏移5个子帧和向前偏移4个子帧后所对应的至少一个所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧7上反馈对应于所述子帧7向前偏移7个子帧和/或向前偏移6个子帧后所对应的所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧8上反馈对应于所述子帧8向前偏移6个子帧、向前偏移5个子帧和向前偏移4个子帧后所对应的至少一个所述辅服务小区的子帧的HARQ-ACK。
当所述主服务小区的上下行配置为上下行配置2时，所述主服务小区的上行子帧包括子帧2和子帧7，在所述主服务小区的子帧2上反馈对应于所述子帧2向前偏移8个子帧、向前偏移7个子帧、向前偏移6个子帧、向前偏移5个子帧和向前偏移4个子帧后所对应的至少一个所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧7上反馈对应于所述子帧7向前偏移8个子帧、向前偏移7个子帧、向前偏移6个子帧、向前偏移5个子帧和向前偏移4个子帧后所对应的至少一个所述辅服务小区的子帧的HARQ-ACK。
当所述主服务小区的上下行配置为上下行配置6时，所述主服务小区的上行子帧包括子帧2、子帧3、子帧4、子帧7和子帧8，在所述主服务小区的子帧2上反馈对应于所述子帧2向前偏移8个和/或向前偏移7个子帧后所对应的所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧3反馈对应于所述子帧3向前偏移7个和/或向前偏移6个子帧后所对应的所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧4上反馈对应于所述子帧4向前偏移6个子帧和/或向前偏移5个子帧后所对应的所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧7上反馈对应于所述子帧7向前偏移7个子帧后所对应的所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧8上反馈对应于所述子帧8向前偏移7个、向前偏移6个子帧和向前偏移5个后所对应的至少一个所述辅服务小区的子帧的HARQ-ACK。
本发明实施例通过重新定义载波聚合中HARQ时序关系，限定主服务小区的上下行配置为上述任一上下行配置，以对满足上述限定条件的载波聚合在TDD某些上下行配置下可以配置多个载波，如，当一辅服务小区配置为上下行配置5时，PUCCH格式3模式可支持多于两个上下行配置5的辅服务小区的CA，并且通过上述载波聚合中HARQ时序关系，能够将需要反馈的HARQ-ACK分散于多个不同的上行子帧进行反馈，缩短了反馈时延并提高反馈性能。
需要说明的是，所述主服务小区的上行子帧包含不属于所述辅服务小区的上行子帧的上行子帧。
在上述实施例的基础上，主服务小区为不同上下行配置时，主服务小区的不同子帧能够反馈的辅服务小区子帧的HARQ-ACK所对应的辅服务小区子帧个数是有差异的，存在以下几种情况：

本发明实施例的设备，可以用于执行如图5所示方法实施例的技术方案，其实现原理和技术效果类似，此处不再赘述。
图4为本发明应答信息的传输方法实施例一的流程示意图。本发明实施例提供一种应答信息的传输方法，该方法应用于LTE TDD系统，可以由应答信息的传输装置执行，该装置可以集成在例如基站等设备中。如图4所示，该方法包括：
S101、确定在辅服务小区上向UE发送PDSCH；
S102、在辅服务小区上向UE发送PDSCH，其中，该辅服务小区为基站为该UE配置的N个TDD辅服务小区中的辅服务小区，N为大于或等于1的自然数。
S103、确定辅服务小区对应的HARQ时序关系，该HARQ时序关系为PDSCH与HARQ-ACK的HARQ时序关系。
S104、根据HARQ时序关系，在主服务小区上接收PDSCH所对应的HARQ-ACK，其中，该主服务小区为基站为上述UE配置的TDD主服务小区。
具体地，UE接入网络建立无线资源控制(Radio Resource Control，简称：RRC)连接以后，基站可以为该UE添加或删除服务小区，例如，根据该UE的业务量和/或功耗能力等，为该UE添加或删除服务小区。当UE被配置多于一个服务小区时，该UE由一个主服务小区和N个辅服务小区提供服务，其中，N小于或等于4，但对于上述主服务小区为上下行配置2，辅服务小区为上下行配置5的CA，PUCCH格式3模式最多支持两个服务小区，即N＝1。具体的，基站可以通过RRC信令为UE添加或删除辅服务小区，或通过切换流程为UE更换主服务小区。本发明实施例针对TDD CA，即该UE所有的服务小区均为TDD服务小区。
UE被基站配置了CA后，基站就可以在辅服务小区上向UE发送PDSCH，该辅服务小区为基站为该UE配置的N个辅服务小区中任意一个。基站确定所述辅服务小区对应的HARQ时序关系，所述HARQ时序关系为PDSCH与HARQ-ACK的HARQ时序关系。为了解决上述两个服务小区限制的问题， 该HARQ时序关系不是当前机制下的参考上下行配置5，而是引入一个新的HARQ时序关系；进而，根据该时序关系，在主服务小区上接收所述PDSCH所对应的HARQ-ACK。
在基站接收或UE发送该HARQ-ACK之前，需要确定承载该HARQ-ACK的PUCCH信道资源，例如，根据RRC信令的配置，确定承载该HARQ-ACK的PUCCH信道资源，或，根据其他与物理下行控制信道隐式对应的资源，确定承载该HARQ-ACK的PUCCH信道资源；还需要确定PUCCH格式3模式下的HARQ-ACK反馈子帧的M值，并进而确定该反馈子帧上所有HARQ-ACK比特的顺序，以及这些比特的总数，即码本大小。这些步骤可以是现有的机制或其他机制，在此不做限定；另外，步骤之间的实施顺序也不做限定。
本发明实施例通过重新定义载波聚合中HARQ时序关系，限定主服务小区的上下行配置为上述任一上下行配置，以对满足上述限定条件的载波聚合在TDD某些上下行配置下可以配置多个载波，如，当一辅服务小区配置为上下行配置5时，PUCCH格式3模式可支持多于两个上下行配置5的辅服务小区的CA，并且通过上述载波聚合中HARQ时序关系，能够将需要反馈的HARQ-ACK分散于多个不同的上行子帧进行反馈，缩短了反馈时延并提高反馈性能。
表4 辅服务小区在主服务小区采用不同上下行配置的情况下分别对应的HARQ时序关系
Figure PCTCN2014086854-appb-000004
其中，表4所示为辅服务小区在主服务小区采用不同上下行配置的情况下分别对应的HARQ时序关系，以下对本发明实施例提供的HARQ时序关系进行详细说明。
如图4所示，该HARQ时序关系包括：所述主服务小区的上下行配置为上下行配置0、上下行配置1、上下行配置2和上下行配置6中任一个。
具体地，当所述主服务小区的上下行配置为上下行配置0时，所述主服务小区的上行子帧包括子帧2、子帧3、子帧4、子帧7、子帧8和子帧9，在所述主服务小区的子帧2上反馈对应于所述子帧2向前偏移5个和/或向前偏移6个子帧后所对应的所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧3反馈对应于所述子帧3向前偏移4个和/或向前偏移5个子帧后所对应的所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧4上反馈对应于所述子帧4向前偏移4个子帧后所对应的所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧7上反馈对应于所述子帧7向前偏移6个和/或向前偏移5个子帧后所对应的所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧8上反馈对应于所述子帧8向前偏移5个和/或向前偏移4个子帧后所对应的所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧9上反馈对应于所述子帧9向前偏移4个子帧后所对应的所述辅服务小区的子帧的HARQ-ACK；
当所述主服务小区的上下行配置为上下行配置1时，所述主服务小区的上行子帧包括子帧2、子帧3、子帧7和子帧8，在所述主服务小区的子帧2上反馈对应于所述子帧2向前偏移7个和/或向前偏移6个子帧后所对应的所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧3反馈对应于所述子帧3向前偏移6个子帧、向前偏移5个子帧和向前偏移4个子帧后所对应的至少一个所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧7上反馈对应于所述子帧7向前偏移7个子帧和/或向前偏移6个子帧后所对应的所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧8上反馈对应于所述子帧8向前偏移6个子帧、向前偏移5个子帧和向前偏移4个子帧后所对应的至少一个所述辅服务小区的子帧的HARQ-ACK；
当所述主服务小区的上下行配置为上下行配置2时，所述主服务小区的上行子帧包括子帧2和子帧7，在所述主服务小区的子帧2上反馈对应于所述子帧2向前偏移8个子帧、向前偏移7个子帧、向前偏移6个子帧、向前偏移5个子帧和向前偏移4个子帧后所对应的至少一个所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧7上反馈对应于所述子帧7向前偏移8个子帧、向前偏移7个子帧、向前偏移6个子帧、向前偏移5个子帧和向前偏移4个子帧后所对应的至少一个所述辅服务小区的子帧的 HARQ-ACK；
当所述主服务小区的上下行配置为上下行配置6时，所述主服务小区的上行子帧包括子帧2、子帧3、子帧4、子帧7和子帧8，在所述主服务小区的子帧2上反馈对应于所述子帧2向前偏移8个和/或向前偏移7个子帧后所对应的所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧3反馈对应于所述子帧3向前偏移7个和/或向前偏移6个子帧后所对应的所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧4上反馈对应于所述子帧4向前偏移6个子帧和/或向前偏移5个子帧后所对应的所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧7上反馈对应于所述子帧7向前偏移7个子帧后所对应的所述辅服务小区的子帧的HARQ-ACK，在所述主服务小区的子帧8上反馈对应于所述子帧8向前偏移7个、向前偏移6个子帧和向前偏移5个后所对应的至少一个所述辅服务小区的子帧的HARQ-ACK。
本发明实施例方案仅考虑主服务小区的TDD上下行配置为如表1所示7种上下行配置中有限的几种，例如，如表4所示，上下行配置0，上下行配置1，上下行配置2和上下行配置6中的任意一种，即下行-上行的转换周期均为5个子帧的长度的上下行配置。辅服务小区可以为如表1所示7种上下行配置中的任何一种，在此不做限定。但对于主辅小区组合有一定限定。具体地，本发明实施例考虑组合场景限制，主服务小区的上行子帧包含不属于辅服务小区的上行子帧的上行子帧，即主服务小区的上行子帧不被辅服务小区的上行子帧所包含。该限定可以分为两种情况：
第一种为主服务小区的上行子帧包含辅服务小区的上行子帧，例如，主辅服务小区组合为(1,2)，(2,5)，(0,5)，或(1,5)等；
第二种为主辅服务小区两者的上行子帧集合互不完全包含，例如，主辅服务小区组合为(2,4)，或(2,3)等。
同时参考表1和表4。例如，当主服务小区的上下行配置为上下行配置0时，主服务小区的子帧2、子帧3、子帧4、子帧7、子帧8和子帧9均为上行子帧，共6个上行子帧；当主服务小区的上下行配置为上下行配置1时，主服务小区的子帧2、子帧3、子帧7和子帧8均为上行子帧，共4个上行子帧，其他上下行配置时类似，以保证反馈性能和时延。
在本发明任一实施例中，当所述主服务小区的上下行配置为上下行配置0时，所述主服务小区的子帧2、子帧3、子帧7和子帧8能够反馈的辅服务小区子帧的HARQ-ACK所对应的辅服务小区子帧个数为2，所述主服务小区的子帧4和子帧9能够反馈的辅服务小区子帧的HARQ-ACK所对应的辅服务小区子帧个数为1；当所述主服务小区的上下行配置为上下行配置1时，所述主服务小区的子帧2和子帧7能够反馈的辅服务小区子帧的HARQ-ACK所对应的辅服务小区子帧个数为2，所述主服务小区的子帧3和子帧8能够反馈的辅服务小区子帧的HARQ-ACK所对应的辅服务小区子帧个数为3；当所述主服务小区的上下行配置为上下行配置2时，所述主服务小区的子帧2和子帧7能够反馈的辅服务小区子帧的HARQ-ACK所对应的辅服务小区子帧个数为5；当所述主服务小区的上下行配置为上下行配置6时，所述主服务小区的子帧2、子帧3和子帧4能够反馈的辅服务小区子帧的HARQ-ACK所对应的辅服务小区子帧个数为2，所述主服务小区的子帧7能够反馈的辅服务小区子帧的HARQ-ACK所对应的辅服务小区子帧个数为1，所述主服务小区的子帧8能够反馈的辅服务小区子帧的HARQ-ACK所对应的辅服务小区子帧个数为3。
其中，表4中，主服务小区子帧序号中的子帧为用于反馈辅服务小区子帧的HARQ-ACK的上行子帧，每一上行子帧所对应的列中各数字分别表示在当前的上行子帧n上需要反馈辅服务小区子帧n-k(k属于K)的这些下行子帧上的PDSCH所对应的HARQ-ACK，例如，对于主服务小区的上下行配置为上下行配置1的主服务小区，主服务小区的子帧n＝2中的K＝{7，6}表示这个n＝2的上行子帧用来反馈辅服务小区子帧n-7和/或n-6这两个下行子帧上的PDSCH所对应的HARQ-ACK，具体地，子帧n-7就是以当前主服务小区的子帧n＝2的子帧时间为基准，往前数7个子帧，即上个无线帧的子帧5；同理，n-6对应子帧6。
本发明实施例通过重新定义载波聚合中HARQ时序关系，限定主服务小区的上下行配置为上述任一上下行配置，以对满足上述限定条件的载波聚合在TDD某些上下行配置下可以配置多个载波，如，当一辅服务小区配置为上下行配置5时，PUCCH格式3模式可支持多于两个上下行配置5的辅服务小区的CA，并且通过上述载波聚合中HARQ时序关系，能够将需要反馈的HARQ-ACK分散于多个不同的上行子帧进行反馈，缩短了反馈时延并提高反 馈性能。
接下来以主辅服务小区组合为(2,5)和主辅服务小区组合为(1,2)为例分别进行详细说明。其中，基于传输模模式的不同，UE包括全双工UE和半双工UE。
一、对于主辅服务小区组合为(2，5)，或主服务小区为上下行配置2，上下行配置5的多个辅服务小区的场景
一种实际应用场景中，UE为全双工UE，即UE支持在两个服务小区上同时接收和发送，例如，假设主服务小区是上行子帧，辅服务小区是下行子帧，全双工UE可以同时在主服务小区上发送信息和在辅服务小区上接收信息。
S104可以包括：根据接收PDSCH对应的HARQ-ACK的子帧确定M值，其中，M值为主服务小区的子帧能够反馈辅服务小区子帧的HARQ-ACK所对应的辅服务小区子帧个数减去辅服务小区子帧中是上行子帧的个数所获得的数值；根据上述M值，确定信道选择模式下的HARQ-ACK反馈表格；根据所述HARQ-ACK反馈表格，在主服务小区上接收PDSCH所对应的HARQ-ACK。
具体地，如表4所示，上下行配置2的主服务小区的子帧2和子帧7为反馈辅服务小区子帧的HARQ-ACK的子帧，UE需要分别确定该子帧的M值。以子帧为子帧2为例，由于子帧2能够反馈辅服务小区子帧的HARQ-ACK所对应的辅服务小区子帧中包含数字集合{8,7,6,5,4}共5个子帧；该数字集合中所有子帧能够反馈的、对应于该上下行配置5的辅服务小区的子帧均为下行子帧或特殊子帧，具体为辅服务小区子帧4，5，6，7和8，因此不需要扣除，即M值为5。
以子帧为子帧7为例，同理，由于子帧7能够反馈辅服务小区子帧的HARQ-ACK所对应的辅服务小区子帧中包含数字集合{8,7,6,5,4}共5个子帧，该数字集合中子帧能够反馈的、对应于该上下行配置5的辅服务小区的上行子帧的个数为1，具体的该上行子帧对应数字集合{8,7,6,5,4}共5个子帧，该数字集合中的数字5对应的该上行子帧为辅服务小区的上行子帧2，那么上行子帧7的M值为5-1＝4。需要说明的是，这里对数字集合中的数字顺序不做限定。
在确定M值之后，基站和UE就可以根据该M值，确定信道选择模式下的HARQ-ACK反馈表格；进一步地，根据该HARQ-ACK反馈表格，在主服务小区上接收PDSCH所对应的HARQ-ACK。另外需要说明的是，由于该例中M值 可以等于5，所以，当UE为全双工UE时，主辅服务小区组合为(2，5)的PUCCH发送模式不支持信道选择模式。
其中，上述HARQ-ACK反馈表格是预先设置的，然后根据M的取值，比如M＝2，或3，或4，来选择对应的表格。当M＝2时，HARQ-ACK反馈表格如表5所示；当M＝3时，HARQ-ACK反馈表格如表6所示；当M＝4时，HARQ-ACK反馈表格如表7所示。在表5、表6和表7中，自每个表格的最左端数起，第一列表示HARQ-ACK的状态，即ACK还是NACK；第二列为选择出的传输HARQ-ACK的信道；第三列表示发送HARQ-ACK的调制符号的状态，其中，N/A表示不考虑。

在本发明实施例中，对全双工UE使用上下行配置5的辅服务小区的情况，可以最多支持3个上下行配置5的辅服务小区，即最多4个服务小区的CA；且对于辅服务小区的HARQ-ACK性能和反馈时延都进行了优化。
另一种实际应用场景中，UE为全双工UE，S104可以包括：根据接收PDSCH对应的HARQ-ACK的子帧确定M值，其中，M值为主服务小区的子帧能够反馈辅服务小区子帧的HARQ-ACK所对应的辅服务小区子帧个数减去所述辅服务小区中是上行子帧的个数所获得的数值；根据上述M值，确定PUCCH格式3模式下的HARQ-ACK的码本大小；根据HARQ-ACK的码本大小，在主服务小区上接收PDSCH所对应的HARQ-ACK。其中，码本大小为HARQ-ACK的信息比特数。比如，若调度了下行数据的一个传输块，则需反馈1比特的HARQ-ACK；如果调度了下行数据的N个传输块，就需反馈N个比特的HARQ-ACK。该应用场景与上一应用场景的区别仅在于根据所确定的M值，所确定PUCCH发送模式的不同，此处不再赘述。
再一种实际应用场景中，UE为半双工UE，即UE不支持在两个服务小区上同时接收和发送，例如，假设主服务小区是上行子帧，辅服务小区是 下行子帧，半双工UE不可以同时在主服务小区上发送信息和在辅服务小区上接收信息。具体的，UE可以采用主服务小区子帧方向优先级高的原则，即UE可以在主服务小区上发送信息，但同时不能辅服务小区上接收信息，当然基站也不会在这个子帧为该UE在辅服务小区上调度下行信息。反之也成立，如果主服务小区是下行子帧，同时辅服务小区是上行子帧，那么UE可以在主服务小区上接收信息，但同时不能辅服务小区上发送信息。
该应用场景中，S104可以包括：根据接收PDSCH对应的HARQ-ACK的子帧确定M值，其中，M值为主服务小区的子帧能够反馈辅服务小区子帧的HARQ-ACK所对应的辅服务小区子帧个数减去所述辅服务小区中是上行子帧的个数，再减去所述辅服务小区子帧中是下行子帧的个数所获得的数值，其中，与下行子帧时刻相同的子帧在所述主服务小区上是上行子帧或特殊子帧；根据上述M值，确定信道选择模式下的HARQ-ACK反馈表格；根据HARQ-ACK反馈表格，在主服务小区上接收PDSCH所对应的HARQ-ACK。
具体的，如表4所示，上下行配置2的主服务小区的子帧2和子帧7为反馈辅服务小区子帧的HARQ-ACK的子帧，UE需要分别确定该子帧的M值。以子帧为子帧2为例，由于子帧2能够反馈辅服务小区子帧的HARQ-ACK所对应的辅服务小区子帧中包含数字集合{8,7,6,5,4}共5个子帧；该数字集合中所有子帧能够反馈的、对应于该上下行配置5的辅服务小区的子帧均为下行子帧或特殊子帧，具体为辅服务小区子帧4，5，6，7和8，但对应于数字5的辅服务小区子帧为子帧7，考虑到主服务小区的子帧7为上行子帧，那么半双工UE在该辅服务小区的子帧7是不可以接收PDSCH的；此外，对应于数字6的辅服务小区子帧为下行子帧6，考虑到主服务小区的子帧6为特殊子帧，那么半双工UE在该辅服务小区的下行子帧6上也是不可以接收PDSCH的，因此，需要减去2个子帧(5和6)，即M值为5-2＝3。可选地，也可以只减去上述子帧中的一个，即可以只减去上述数字为5对应的辅服务小区的子帧7，而不减去上述数字为6对应的辅服务小区的子帧6，此时M值为4；也可以只减去上述数字为6对应的辅服务小区的子帧6，而不减去上述数字为5对应的辅服务小区的子帧7，此时M值也为4。
以子帧为子帧7为例，由于子帧2中能够反馈辅服务小区子帧的HARQ- ACK所对应的辅服务小区子帧中包含数字集合{8,7,6,5,4}共5个子帧，而该数字集合中子帧能够反馈的、对应于该上下行配置5的辅服务小区的上行子帧的个数为1，具体的该数字集合中数字5对应的上行子帧为辅服务小区的上行子帧2，则该子帧7上的M值为5-1＝4。本发明实施例中，对数字集合中的数字顺序不做限定。
在确定M值之后，基站和UE就可以根据该M值确定信道选择模式下的HARQ-ACK反馈表格；进一步地，根据该HARQ-ACK反馈表格，在主服务小区上接收PDSCH所对应的HARQ-ACK。该发明实施例中，由于M值都小于或等于4，所以，当UE为半双工UE时，主辅服务小区组合为(2,5)的PUCCH发送模式可以支持信道选择模式。
在本发明实施例中，对半双工UE使用上下行配置5的辅服务小区的情况，可以最多支持4个上下行配置5的辅服务小区，即最多5个服务小区的CA；且对于辅服务小区的HARQ-ACK性能和反馈时延都进行了优化。
又一种实际应用场景中，UE为半双工UE，S104可以包括：根据接收PDSCH对应的HARQ-ACK的子帧确定M值，其中，M值为主服务小区的子帧能够反馈辅服务小区子帧的HARQ-ACK所对应的辅服务小区子帧个数减去所述辅服务小区中是上行子帧的个数，再减去所述辅服务小区中是下行子帧的个数所获得的数值，其中，与下行子帧时刻相同的子帧在所述主服务小区上是上行子帧或特殊子帧；根据所述M值，确定PUCCH格式3模式下的HARQ-ACK的码本大小；根据HARQ-ACK的码本大小，在主服务小区上接收PDSCH所对应的HARQ-ACK。该应用场景与上一应用场景的区别仅在于根据所确定的M值，所确定PUCCH发送模式的不同，此处不再赘述。
二、对于主辅服务小区组合为(1,2)，或主服务小区为上下行配置1，上下行配置2的多个辅服务小区的场景
具体地，在表8中，根据辅服务小区的当前时序，主辅服务小区组合(1,2)下的上下行配置2的辅服务小区的参考上下行配置为辅服务小区自身的上下行配置2。如表8所示，可以看到反馈该辅服务小区的HARQ-ACK的子帧为主服务小区的4个上行子帧中的两个，且各自的M值均为4；采用辅服务小区的新时序后，表8的新时序和表4对于主辅小区组合(1,2)是一致的，获取M值的方法也是一致的。另外，采用新时序之后，反馈辅服务小区的HARQ-ACK的 子帧扩展到了所有主服务小区的上行子帧上，因此，优化了M值在多个子帧间的平衡，且由于M值的减小带来了性能的提升。此外，对于部分子帧的反馈延时也进行了优化，例如，PDSCH子帧4和子帧9的反馈时延缩短了一个4个子帧。

该实施例对其他TDD CA组合满足条件“主服务小区的上行子帧不被辅服务小区的上行子帧所包含”的情况，若不考虑上下行配置5，可以最多支持5个服务小区的CA；且，对于辅服务小区的HARQ-ACK性能和反馈时延都进行了优化。
这里仅说明全双工UE对应的场景，对于半双工UE对应的场景与上述实施例类似，此处不再赘述。
另外，由于当前系统中存在双工能力的上报，所以本发明用于指示所述UE为全双工UE或半双工UE的信令，可以与当前系统中的双工能力上报复用一条信令，也可以是独立于当前系统中的半双工能力。
在上述实施例的基础上，S101之前，该方法还可以包括：接收UE上报的能力信息，该能力信息用于指示UE是否支持HARQ时序关系；并，根据该能力信息，确定所述UE支持所述HARQ时序关系。
具体的，由于当前系统中存在已有的TDD CA下的HARQ时序关系，暂且叫做原HARQ时序关系；新添加的能力信息引入了上述HARQ时序关系。此外，鉴于当前系统中还支持TDD-FDD的CA，因此，该能力信息的上报可以与上述TDD-FDD CA的能力绑定或复用一条上报信令，即一旦UE上报了支持TDD-FDD CA的能力，那么该UE也就同时具备了支持上述HARQ时序关系的能力。可选地，也可以是独立于当前系统中的TDD-FDD CA能力的能力上报。
在上述实施例中，所述主服务小区的上下行配置满足下述条件中的至少 一个：
条件一：当所述主服务小区的上下行配置为上下行配置0时，所述主服务小区的子帧2、子帧3、子帧4、子帧7、子帧8和子帧9中至少一个子帧所反馈的辅服务小区的子帧的HARQ-ACK所对应的辅服务小区的子帧减少至少一个。
条件二：当所述主服务小区的上下行配置为上下行配置1时，所述主服务小区的子帧2、子帧3、子帧7和子帧8中至少一个子帧所反馈的辅服务小区的子帧的HARQ-ACK所对应的辅服务小区的子帧减少至少一个。
条件三：当所述主服务小区的上下行配置为上下行配置2时，所述主服务小区的子帧2和子帧7中至少一个子帧所反馈的辅服务小区的子帧的HARQ-ACK所对应的辅服务小区的子帧减少至少一个。
条件四：当所述主服务小区的上下行配置为上下行配置6时，所述主服务小区的子帧2、子帧3、子帧4、子帧7和子帧8中至少一个子帧所反馈的辅服务小区的子帧的HARQ-ACK所对应的辅服务小区的子帧减少至少一个。
可选地，所述辅服务小区的TDD上下行配置可以为上下行配置5。当所述辅服务小区的上下行配置为5时，所述主服务小区的上下行配置满足上述条件中的至少一。且此时仍具有本发明实施例的效果：在TDD某些上下行配置下可以配置多个载波，如，当一辅服务小区配置为上下行配置5时，PUCCH格式3模式可支持多于两个上下行配置5的辅服务小区的CA，并且通过上述载波聚合中HARQ时序关系，能够将需要反馈的HARQ-ACK分散于多个不同的上行子帧进行反馈，缩短了反馈时延并提高反馈性能。
