Description

基于HARQ的消息反馈方法及装置 技术领域
本发明涉及通信技术，尤其涉及一种基于HARQ的消息反馈方法及装置。
背景技术
混合式自动重传请求(Hybrid Automatic Repeat request，简称HARQ)是一种结合前向纠错(Forward Error Correction，简称FEC)和自动重传请求(Automatic Repeat request，简称ARQ)方法的技术。其中，FEC通过添加冗余信息，使得接收端能够纠正一部分错误，从而减少重传的次数，对于FEC无法纠正的错误，接收端会通过ARQ机制请求发送端重发数据。具体实现过程中，接收端使用检错码来检测收到的数据包是否出错，如果无错，则接收端向发送端发送一个确认(Acknowledgement，简称ACK)，如果出错，则接收端向发送端发送一个否定确认(Negative Acknowledgement，简称NACK)，发送端收到NACK后，会重发数据包。
现有技术中，接收端接收数据包后，会按照预设的时序回复ACK或NACK。为了提供更大的带宽，长期演进(Long Term Evolution，简称LTE)引入了载波聚合(Carrier Aggregation，简称CA)技术，针对聚合后的载波，如果还采用现有的时序回复ACK或NACK，会造成资源浪费或无法回复ACK或NACK。

具体实施方式
基站：又称为无线接入网(Radio Access Network，RAN)设备，是一种将终端接入到无线网络的设备，可以是全球移动通讯(Global System of  Mobile communication，简称GSM)或码分多址(Code Division Multiple Access，简称CDMA)中的基站(Base Transceiver Station，简称BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，简称WCDMA)中的基站(NodeB，简称NB)，还可以是长期演进(Long Term Evolution，简称LTE)中的演进型基站(Evolutional Node B，简称eNB或eNodeB)，或者中继站或接入点，或者未来5G网络中的基站等，在此并不限定。
终端：可以是无线终端也可以是有线终端，无线终端可以是指向用户提供语音和/或其他业务数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(Radio Access Network，简称RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service，简称PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol，简称SIP)话机、无线本地环路(Wireless Local Loop，简称WLL)站、个人数字助理(Personal Digital Assistant，简称PDA)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device or User Equipment)，在此不作限定。
本发明实施例中，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
载波聚合(Carrier Aggregation，简称CA)是将2个或更多的载波单元(Component Carrier，简称CC)聚合在一起形成载波组以支持更大的传输带宽。在CA场景下，多个载波单元可以分组工作。目前3GPP标准支持两个分组，一个可以称为“主物理上行控制信道(Physical Uplink Control  Channel，简称PUCCH)组(primary PUCCH group)”，另一个可以称为“辅PUCCH组(secondary PUCCH group)”，一个组内通过一个载波反馈该组内多个载波的HARQ的ACK/NACK信息，即一个组中所有载波收到数据包后的反馈信息(ACK或NACK)都由一个指定的载波来回复。载波聚合中，主小区(Primary cell，简称Pcell对应的载波称为主分量载波(Primary Component Carrier，简称PCC)，也称作主载波；辅小区(Secondary Cell，简称Scell)对应的载波称为辅分量载波(Secondary Component Carrier，简称SCC)，也称为辅载波。主小区负责基站与终端之间的无线资源控制(Radio Resource Control，简称RRC)；辅小区用于提供额外的无线资源，与终端之间不存在RRC通信。
PCell是primary PUCCH group中用来反馈HARQ的ACK/NACK信息的载波，在secondary PUCCH group中也有一个载波用来反馈HARQ的ACK/NACK信息，这个载波被称为PUCCH-SCell。随着技术的发展，载波分组的个数可以不限制为2个。由于在每个载波分组中，HARQ反馈信息(即HARQ的ACK/NACK信息)的发送原则是相同的，因此为了简单起见本发明只针对一个载波组的情况进行说明，用于反馈HARQ信息的载波统称为反馈载波。本发明的方案可以自动扩展到多个载波组的情况。
另外，需要说明的是，载波聚合下辅载波的下行HARQ时序是相对于反馈载波的，因此时序的关系只用考虑被反馈载波和反馈载波两个载波即可。
在LTE的TDD模式下，上下行配比用于表示在一个无线帧内上、下行子帧、以及特殊子帧的个数以及位置，也可以简称为配比。
图1为本发明提供的基于HARQ的消息反馈方法的应用场景示意图，如图1所示，该场景包括：基站01、终端02。
图1中终端02可以通过多个载波与基站01进行通信。
图2为载波调度方式示意图。
载波聚合中各载波的资源调度方式可以分为跨载波调度和自调度(即非跨载波调度)。跨载波调度指的是一个载波的资源是通过另一个载波进行调度的。
自调度(非跨载波调度)指的就是本载波的资源由本载波的控制信道进行调度。
基于载波指示域(Carrier Indicator Field，简称CIF)的跨载波调度允许一个服务小区(serving cell)的PDCCH调度另一服务小区上的无线资源，即控制信息在一个载波单元上传输，而对应的数据在另一个载波单元上传输，即PDCCH在一个小区上传输，但对应的PDSCH或物理上行共享信道(Physical Uplink Shared Channel，简称PUSCH)在另一个小区上传输。一般地，主小区通过自身的PDCCH进行调度，而当辅小区没有配置PDCCH时，可以通过另一个服务小区的PDCCH进行调度。需要说明的是这里的服务小区和载波是等价的概念，一个服务小区即一个载波。
如果一个终端支持载波聚合，那么这个终端对应的多个服务小区可以有如下几种配置方式：(1)其中某个服务小区的资源由本载波的PDCCH进行调度，即自调度(非跨载波调度)。(2)某个服务小区的资源被其它服务小区跨载波调度，PDCCH在调度载波上发送，那么该服务小区称为跨载波调度。
如图2所示，CC1和CC3都是非跨载波调度，即本载波的资源由本载波的PDCCH信令来调度。CC2和CC4都是跨载波调度，且都由CC1进行调度。
图2中，PDCCH可以用来调度物理下行共享信道(Physical Downlink Shared Channel，简称PDSCH)的下行资源；或者，PDCCH也可以用来调度物理上行共享信道(Physical Uplink Shared Channel，简称PUSCH)的上行资源。
对于下行HARQ，即终端对基站发送的下行数据进行确认的处理流程，下行数据的发送和确认消息的回复有一定的时序关系，在时分双工(Time Division Duplexing，简称TDD)场景下，多个下行子帧发送的数据包可能需要在同一上行子帧上回复ACK或NACK，例如当终端在第n-k个子帧(下行子帧)上检测到下行数据包时，终端会在第n个子帧(上行子帧)上回复ACK或NACK。
对于上行HARQ，即基站对终端发送的上行数据进行确认的处理流程，上行的时序关系包括两个：一个是上行数据的调度时序(也可以称为UL grant时序)，表示当终端在第n个子帧(下行子帧)检测到PDCCH中的上行调度信息后，会在第n+k个子帧(上行子帧)发送物理上行共享信道(Physical Uplink Shared Channel，简称PUSCH)数据；另一个是上行数据的HARQ反馈消息回复时序(也可以称为物理混合ARQ指示信道(Physical Hybrid ARQ  Indicator Channel简称PHICH)时序)，TDD场景下，类似地，当基站在第n-k个子帧(上行子帧)上检测到上行数据包时，基站会在第n个子帧(下行子帧)上回复ACK或NACK。其中，n和k都是大于0的正整数。
如上所述，针对单个载波存在预设的下行和上行HARQ时序。以下行HARQ时序为例，当终端在第n-k个子帧(下行子帧)上检测到下行数据包时，终端会在第n个子帧(上行子帧)上回复ACK或NACK。这里的k和n值在每种TDD的上下行配比下都有确定的数值进行对应。
载波聚合后，现有技术中一般会根据不同的载波资源调度方式选择一个已有的单载波的HARQ信息反馈时序作为载波聚合后辅载波的HARQ时序或者选择反馈载波和被反馈载波共有的上行子帧位置进行反馈。
图3为本发明提供的一种TDD的上下行配比示意图。
以下行HARQ时序为例，载波聚合中各载波的上下行配比可能不同，如果只依据另一个载波的预设时序确定辅载波的HARQ反馈时序的话，由于不同上下行配比所对应的上下行子帧位置不同，会导致某些载波的下行子帧没有对应的上行子帧进行HARQ信息反馈。例如载波1的子帧n为上行子帧，对应下行子帧n-k的HARQ信息反馈，在该载波1上子帧n本身是上行子帧因此不需要考虑其HARQ反馈子帧，也就不存在子帧n的HARQ反馈时序。但载波2与载波1有不同的上下行配比，该载波在子帧n的位置是下行子帧，如果选择载波1的HARQ反馈时序作为载波2的HARQ反馈时序的话，那么载波2的下行子帧n由于没有对应的上行反馈子帧而无法正常使用。如图3所示，第一载波的上下行配比为“TDD上下行配比1”、第二载波的上下行配比为“TDD上下行配比2”，第一载波为PCell，第二载波为SCell。根据现有技术当SCell采用跨载波调度时(即被PCell调度)，其HARQ时序需要采用主载波配比的下行HARQ时序，即“TDD上下行配比1”的下行HARQ时序。由于上下行配比1的子帧3和子帧8为上行子帧，因此其下行HARQ时序中不包括这两个帧的HARQ反馈位置，而上下行配比2下，子帧3和子帧8为下行子帧，由于下行HARQ反馈时序需要按照PCell的上下行配比1的时序来反馈，辅载波上由于子帧3和子帧8无对应的HARQ反馈子帧，因此导致SCell的子帧3和子帧8不能作为正常下行子帧进行数据发送，从而导致资源的浪费。
另外，在新的TDD上下行配比(包括定义新的上下行配比格式，或者对现有上下行配比的平移)引入后，使用新上下行配比的TDD载波进行载波聚合时，同样会出现某些载波的上行子帧对应另一些载波的下行子帧位置，如果采用现有技术同样会导致资源浪费。新TDD上下行配比的例子如图5所示。其中TDD上下行配比1是现有的一种TDD上下行配比，基于上下行配比1的向右循环移位2个子帧所得到的一个新的TDD上下行配比可以表示为TDD上下行配比7。在上下行配比的表示上两种表示方式等价，为了简单起见后面的描述中仅采用类似上下行配比7的循环移位表示方法来表示新的上下行配比。
本发明实施例针对载波聚合的场景，提出一种新的HARQ信息反馈方法，尽量考虑载波聚合中各载波的上下行配比来进行消息反馈。
图4为本发明实施例提供的一种基于HARQ的消息反馈方法的流程示意图，如图4所示，该方法包括：
S101、终端在载波聚合组的第一下行子帧上接收基站发送的数据包，其中，该载波聚合组包括：第一载波和第二载波。
其中，上述数据包可以为物理下行共享信道(Physical Downlink Shared Channel，简称PDSCH)数据包，或者，用于指示下行半持续调度(Semi-Persistent Scheduling，简称SPS)释放的物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)数据包，在此不作限制。
载波聚合组可以包括多个载波，上述第一载波和第二载波是泛指概念。
上述第一下行子帧可以是载波聚合组中的任一下行子帧。
S102、终端根据载波聚合组中上述第一载波的上下行配比和第二载波的上下行配比，确定第一时序。
其中，第一载波的上下行配比和/或第二载波的上下行配比为除TDD上下行配比0-6之外的其他上下行配比。
即第一载波和第二载波中至少1个的上下行配比是新的上下行配比。新的上下行配比可以是与现有TDD上下行配比0-6完全不同的上下行配比，也可以是将现有TDD上下行配比平移后的上下行配比，在此不作限定。
S103、终端根据上述第一时序在上述第一载波的上行子帧中确定第一上行子帧，或者，在第二载波的子帧中确定第一上行子帧。
载波聚合组中一般包括一个主载波和至少1个辅载波，一般地，上述第一载波代表主载波，第二载波代表辅载波。
本实施例中，载波聚合组中各载波上收到的下行数据包在第一载波上进行回复，或者，在第二载波上进行回复，可以预先配置好，在此不作限制。
可选地，如果是非跨载波调度，就在本载波的子帧中确定第一上行子帧，如果是跨载波调度，就在其调度载波的子帧中确定第一上行子帧。
这里的载波聚合场景可以是现有的TDD各种上下行配比的载波聚合，也可以是新的上下行配比的载波聚合。
本发明实施例中提到的载波聚合组中所包含的多个载波可以是上下行配比均相同，也可以存在不同的上下行配比，在此不作限制。
S104、终端在上述第一上行子帧上向基站发送HARQ反馈消息。
HARQ反馈消息指如果正确接收到数据包则回复ACK，否则回复NACK。
本实施例中，终端在第一下行子帧上接收基站发送的数据包，根据载波聚合组中上述第一载波的上下行配比和第二载波的上下行配比，确定第一时序，并根据第一时序在第一载波或第二载波的子帧上确定第一上行子帧，进而在第一上行子帧上向基站发送反馈消息。本发明实现了根据整个载波聚合的上下行配比确定时序，并确定回复反馈消息的子帧，即提供一种适用于载波聚合后的消息反馈方法，以保证下行子帧上收到的数据包有对应的上行子帧进行反馈，尽量避免资源浪费。
可选地，终端根据上述第一载波的上下行配比和第二载波的上下行配比，确定第一时序，可以是：终端先获取第一载波的上下行配比和第二载波的上下行配比，进而终端根据第一载波的上下行配比和第二载波的上下行配比上下行配比确定上述第一时序。
需要说明的是，终端可以有多种预设时序，第一时序为其中一种，这多种预设时序可以是终端中预先配置的，也可以是由上层信令通知的，在此不作限制。还可以预先配置好上下行配比与时序的映射关系，获取第一载波的上下行配比和第二载波的上下行配比后，根据上下行配比与时序的映射关系就可以确定对应的第一时序。
可选地，终端可以在连接建立时确定主载波，并读取主小区对应基站发送的系统消息，例如系统消息块(system information block，简称SIB)， 具体可以是SIB1，进而根据系统消息获取该主载波的上下行配比。
终端可以接收无线资源控制(Radio Resource Control，简称RRC)连接重配置消息，并根据RRC连接重配置消息添加/修改/释放辅小区，并从RRC连接重配置消息中读取辅载波的上下行配比。
上述第一时序用于指示第一下行子帧为第n-k个子帧时，上述第一上行子帧为第n个子帧，其中，n和k均为大于0的正整数。
此处k与上述第一上行子帧相对应，每个用于发送反馈消息的上行子帧可以对应至少1个k值。也就是说，第一载波中的多个上行子帧中有部分或全部用于发送反馈消息，假设第一载波的第n个上行子帧用于回复反馈消息，这个子帧反馈的ACK/NACK对应于向前间隔k个子帧的下行子帧n-k上数据包的接收情况。
可选地，k大于或等于4。
从不同的角度出发，不同时序方案中各子帧对应的k值可能不同，具体通过下述示例说明：
图5为本发明实施例提供的基于HARQ的消息反馈方法中的一种时序示意图，如图5所示，第一载波的上下行配比采用“TDD上下行配比1”，第二载波的上下行配比采用“平移两个子帧的TDD上下行配比1(例如可以记为TDD配比8)”，其中，带斜纹的格子标识“下行子帧”，带点的格子标识“上行子帧”，空白格子标识“特殊子帧”。各子帧对应的k值如表1所示，
表1 下行HARQ时序中的k值表
Figure PCTCN2016103852-appb-000001
如表1所示，第一载波的子帧编号为2的上行子帧对应的k值为6，即该子帧编号为2的上行子帧所反馈的ACK对应于向前间隔6个子帧的下行子帧所接收的数据包；第一载波的子帧编号为3的上行子帧对应的k值为5和6，即该子帧编号为3的上行子帧所反馈的ACK对应于向前间隔5和/或6个子帧的下行子帧所接收的数据包。其他类似，在此不再赘述。
图5和表1所示的时序，主要考虑了在各种载波聚合的调度方式下如何 在不损失任何一个下行子帧资源的情况下完成HARQ信息反馈问题，此外这种新的时序设计还考虑了第一载波中各上行子帧的负载，以实现每个上行子帧进行消息反馈带来的负载相对均衡。
图6为本发明实施例提供的基于HARQ的消息反馈方法中的另一种时序示意图，如图6所示，第一载波的上下行配比采用“TDD配比1”，第二载波的上下行配比采用“平移两个子帧的TDD配比1”，其中，带斜纹的格子标识“下行子帧”，带点的格子标识“上行子帧”，空白格子标识“特殊子帧”。各子帧对应的k值如表2所示，
表2
Figure PCTCN2016103852-appb-000002
如表2所示，第一载波的子帧编号为2的上行子帧对应的k值为5和6，即该子帧编号为2的上行子帧所反馈的ACK对应于向前间隔5和/或6个子帧的下行子帧所接收的数据包。其他类似，在此不再赘述。
图6和表2所示的时序，主要考虑的是在各种载波聚合的调度方式下如何在不损失任何一个下行子帧资源的情况下完成HARQ信息反馈问题，此外还考虑了尽可能快速进行反馈，因而尽可能采用距离第一下行子帧较近的上行子帧向基站回复反馈消息，在考虑快速反馈的基础上可以再兼顾上行子帧的负载均衡。
图7为本发明实施例提供的基于HARQ的消息反馈方法中的另一种时序示意图，如图7所示，第一载波的上下行配比采用“TDD配比1”，第二载波的上下行配比采用“平移两个子帧的TDD配比1”，其中，带斜纹的格子标识“下行子帧”，带点的格子标识“上行子帧”，空白格子标识“特殊子帧”。各子帧对应的k值如表3所示，
表3
Figure PCTCN2016103852-appb-000003
如表3所示，第一载波的子帧编号为3的上行子帧对应的k值为7和6， 即该子帧编号为2的上行子帧所反馈的ACK对应于向前间隔7和/或6个子帧的下行子帧所接收的数据包。其他类似，在此不再赘述。
图7和表3所示的时序，是在主小区和辅小区均为TDD小区时，沿用了主小区为TDD小区、且辅小区为频分双工(Frequency Division Duplexing，简称FDD)小区下的时序，即不采用新的时序，但是应用到该场景也不会造成资源浪费。
上述实施例中，某个上行子帧对应多个k值，即该子帧回复的ACK可以对应至少1个下行子帧收到的数据包，以表3为例，第一载波的子帧编号为2的上行子帧，向前间隔7和/或6个子帧的下行子帧中，如果在向前间隔7的下行子帧上检测到数据包，那么这个编号为2的上行子帧回复的ACK就对应向前间隔7的下行子帧，如果向前间隔7和6的下行子帧都检测到数据包，那么这个编号为2的上行子帧回复的ACK就同时对应向前间隔7和6的下行子帧上的数据包，在此不作限制。
当然，并不以上述举例为限：
可选地，第一载波的上下行配比采用“TDD配比2”，第二载波的上下行配比采用“平移两个子帧的TDD配比2”，各子帧对应的k值如表4所示：

其具体反馈方法均可参照前述实施例，在此不再赘述。
由上述实施例可知，载波聚合组中每个下行子帧上收到的数据包都有对应的上行子帧进行反馈，没有资源浪费。进一步地，还可以看出，实现了每个上行子帧携带的反馈消息(ACK或NACK)尽量平均，而不会某个上行子帧携带特别多的反馈消息。当然不以上述时序为限，其他上下行配比的组合均可参照前述实施例实现。
图8为本发明实施例提供的一种基于HARQ的消息反馈方法的流程示意图，与图8所示实施例类似地，针对上行HARQ，也需要提供一种消息反馈方法，如图8所示，该方法包括：
S201、基站在载波聚合组的第三上行子帧上接收终端发送的数据包，其中，该载波聚合组包括：第一载波或第二载波。
上述数据包可以是物理上行共享信道(Physical Uplink Shared Channel，简称PUSCH)数据包，在此不作限制。
具体地，该第三上行子帧可以属于第一载波，也可以属于第二载波，在此不作限制。
S202、基站根据上述第一载波的上下行配比和第二载波的上下行配比，确定第三时序。
其中，所述第一载波的上下行配比和/或所述第二载波的上下行配比为除时分双工TDD上下行配比0-6之外的其他上下行配比。
S203、基站根据上述第三预设时序在第一载波的子帧中确定第三下行子帧，或者，在上述第二载波的子帧中确定第三下行子帧。
可选地，如果是非跨载波调度，就在本载波的子帧中确定第三下行子帧， 如果是跨载波调度，就在其调度载波的子帧中确定第三下行子帧。
载波聚合组中一般包括一个主载波和至少1个辅载波，一般地，上述第一载波代表主载波，第二载波代表辅载波，也可以反之，但并不以此为限。
本实施例中，载波聚合组中各载波上收到的数据包都在第一载波上进行回复。
这里的载波聚合场景可以是现有的TDD各种上下行配比的载波聚合，也可以是新上下行配比的载波聚合或现有上下行配比平移后的载波聚合。
S204、基站在上述第三下行子帧上向终端发送反馈消息。
如果正确接收到数据包则回复ACK，否则回复NACK。
本实施例中，基站在第三上行子帧上接收终端发送的数据包，根据上述第一载波的上下行配比和第二载波的上下行配比，确定第三时序，并根据上述第三时序在第一载波的子帧或第二载波的子帧中确定第三下行子帧，并在上述第三下行子帧上向终端回复反馈消息，实现了根据整个载波聚合的上下行配比确定时序，并确定回复反馈消息的子帧，以保证上行子帧上收到的数据包有对应的下行子帧进行反馈，尽量避免资源浪费。
可选地，基站根据上述第一载波的上下行配比和第二载波的上下行配比，确定第三时序，包括：基站获取第一载波的上下行配比和第二载波的上下行配比；基站根据第一载波的上下行配比和第二载波的上下行配比、以及上下行配比与时序的映射关系，确定上述第三时序。
需要说明的是，基站可以有多种预设时序，第三预设时序为其中一种，这多种预设时序可以是基站中预先配置的，也可以是由上层信令通知的，在此不作限制。上下行配比与时序的映射关系也可以是预先配置的，或者由上层信令通知的。
上述第一载波可以是主载波、也可以是辅载波，类似地，上述第二载波可以是主载波也可以是辅载波，在此不作限制。具体主载波和辅载波的上下行配比获取方式可以参见前述方法实施例，在此不作限制。
可选地，上述第三时序用于指示当第三上行子帧为第n2-k2个子帧时，上述第三下行子帧为第n2个子帧，其中，n2和k2均为大于0的正整数，此处k2与上述第三下行子帧相对应，每个用于发送反馈消息的下行子帧可以对应至少1个k2值。也就是说，第一载波中的多个下行子帧中有部分或全部用 于发送反馈消息，假设第一载波的第n2个下行子帧用于回复反馈消息，这个子帧反馈的ACK/NACK可以对应于向前间隔k2的上行子帧上所收到的数据包。
可选地，k2大于或等于4。
图9为本发明实施例提供的基于HARQ的消息反馈方法中的另一种时序示意图，如图9所示，第一载波采用“TDD配比1”，第二载波采用“平移两个子帧的TDD配比1”，其中，带斜纹的格子标识“下行子帧”，带点的格子标识“上行子帧”，空白格子标识“特殊子帧”。各子帧对应的k2值如表8所示，其中最后一行为k2值，
表8
Figure PCTCN2016103852-appb-000009
如表8所示，第一载波的子帧编号为0的下行子帧对应的k2值为6，即该子帧编号为0的下行子帧所反馈的ACK对应于向前间隔6个子帧的上行子帧所接收的数据包。
图10为本发明实施例提供的基于HARQ的消息反馈方法中的另一种时序示意图，如图10所示，第一载波和第二载波上下行配比不同，第一载波采用“TDD上下行配比2”、第二载波采用“平移两个子帧的TDD配比1”，其中，带斜纹的格子标识“下行子帧”，带点的格子标识“上行子帧”，空白格子标识“特殊子帧”。各子帧对应的k2值如表9所示，其中最后一行为k2值，
表9
Figure PCTCN2016103852-appb-000010
如表9所示，第一载波的子帧编号为0的下行子帧对应的k2值为6，即该子帧编号为0的下行子帧所反馈的ACK对应于向前间隔6个子帧的上行子帧所接收的数据包。
由图9、图10所示的实施例可以看出，采用上述方法进行反馈，每个收 到数据包的上行子帧都有对应的下行子帧进行反馈，不会存在资源浪费，且每个下行子帧的负载尽量均衡，避免某个下行子帧承担过多的反馈消息。
在上述实施例的基础上，可选地，终端的资源分配信息(包括上行资源和下行资源)可以通过PDCCH上的DCI信息来获取。
图11为本发明实施例提供的另一种基于HARQ的子帧调度方法的流程示意图，对于载波聚合组，需要进行跨载波调度时也要遵循一定的时序，本实施例提供一种调度方法，如图11所示，该方法包括：
S301、基站根据载波聚合组中第一载波的上下行配比和第二载波的上下行配比，确定第二时序。
与前述实施例相同，载波聚合组包括：第一载波和第二载波。
其中，第一载波的上下行配比和/或第二载波的上下行配比为除TDD上下行配比0-6之外的其他上下行配比。
即第一载波和第二载波中至少1个的上下行配比是新的上下行配比，新的配比可以是与现有TDD上下行配比0-6完全不同的上下行配比，也可以是将现有TDD上下行配比平移后的上下行配比，在此不作限定。
S302、基站根据第二预设时序在第一载波的子帧中确定待调度上行子帧对应的第二下行子帧，或者在第二载波的子帧中确定第二下行子帧。
可选地，如果是非跨载波调度，就在本载波的子帧中确定第二下行子帧，如果是跨载波调度，就在其他载波的子帧中确定第二下行子帧。上下行配比上下行配比
S303、基站在上述第二下行子帧上发送第二上行子帧的调度信息。
S304、基站在上述第二上行子帧上接收终端发送的数据包。
本实施例中，基站根据载波聚合组中第一载波的上下行配比和第二载波的上下行配比，确定第二时序上下行配比，并根据第二时序确定第二下行子帧，进而在上述第二下行子帧上发送第二上行子帧的调度信息，在第二上行子帧上接收终端发送的数据包，实现了根据整个载波聚合的上下行配比对应的时序确定下行子帧发送调度信息，以保证待调度上行子帧有对应的下行子帧进行调度，避免资源浪费。
可选地，基站根据载波聚合组中第一载波的上下行配比和第二载波的上 下行配比，确定第二时序，包括：基站获取第一载波的上下行配比和第二载波的上下行配比上下行配比上下行配比；基站根据第一载波的上下行配比和第二载波的上下行配比、以及子帧配置与时序的映射关系，上下行配比上下行配比确定上述第二时序。
需要说明的是，基站可以有多种预设时序，第二预设时序为其中一种，这多种预设时序可以是基站中预先配置的，也可以是由上层信令通知的，在此不作限制。子帧配置与时序的映射关系也可以是预先配置的，或者由上层信令通知的。
上述第一载波可以是主载波、也可以是辅载波，类似地，上述第二载波可以是主载波也可以是辅载波，在此不作限制。具体主载波和辅载波的上下行配比获取方式可以参见前述方法实施例，在此不作限制。
第二时序用于指示当待调度上行子帧为第n1+k1个子帧时，上述第二下行子帧为第n1个子帧，其中，n1和k1均为大于0的正整数。
此处k1与上述第二下行子帧对应，每个用于调度下行子帧的上行子帧可以对应至少1个k1值。
可选地，k1大于或等于4。
图12为本发明实施例提供的基于HARQ的消息反馈方法中的另一种时序示意图，如图12所示，第一载波采用“TDD上下行配比1”，第二载波采用“平移两个子帧的TDD配比1”，其中，带斜纹的格子标识“下行子帧”，带点的格子标识“上行子帧”，空白格子标识“特殊子帧”。各子帧对应的k1值如表10所示，其中最后一行为k1值，
表10
如表10所示，第一载波的子帧编号为0的下行子帧对应的k1值为4，即该子帧编号为0的下行子帧可用于调度向前间隔4个子帧的上行子帧。
图13为本发明实施例提供的基于HARQ的消息反馈方法中的另一种时序示意图，如图13所示，第一载波和第二载波上下行配比不同，假设第一载波采用“上下行配比2”、第二载波采用“平移两个子帧的TDD上下行配比 1”，其中，带斜纹的格子标识“下行子帧”，带点的格子标识“上行子帧”，空白格子标识“特殊子帧”。各子帧对应的k1值如表11所示，其中最后一行为k1值，
表11
Figure PCTCN2016103852-appb-000012
如表11所示，第一载波的子帧编号为0的下行子帧对应的k1值为4，即该子帧编号为0的下行子帧可用于调度向前间隔4个子帧的上行子帧。
由图12、图13实施例可以看出，采用这种上述方法进行调度，每个需要调度的上行子帧都有对应的下行子帧进行调度，而不会存在资源浪费。
