混合自动重传请求HARQ码本的生成方法及相关设备

技术领域
本申请涉及通信领域，尤其涉及HARQ码本的生成方法及相关设备。
背景技术
为了更好的满足日益增长的业务类型需求，在新的接入技术，例如5G技术中，要求支持除了长期演进(Long Term Evolution，LTE)中已经支持的增强移动宽带(Enhanced Mobile Broadband，eMBB)和广播业务外，又额外引入了高可靠低延迟通信(Ultra-Reliable and Low Latency Communications，URLLC)和大规模机器通信(massive Machine Type Communication，mMTC)两种新的业务类型。其中，每种业务类型的业务特点都具有明显的差异性，因此每种业务对于子载波间隔及符号长度等系统参数的需求不同。
为满足不同业务类型对于载波参数的需求，在LTE-Advanced中，第三代合作伙伴计划(Third Generation Partnership Project，3GPP)提出了载波聚合技术，它很好地将多个载波聚合成一个更宽的频谱，同时也可以把一些不连续的频谱聚合到一起。
但是被聚合的载波使用的传输时间单位都相同，都为1ms。而在New Radio(NR)中，会存在聚合的载波使用的传输时间单位不同的情况，当传输时间单位不同时，接入网设备下发给终端的下行数据，终端根据之前的传输时间单位相同的情况下设置的混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)反馈的HARQ码本，对于传输时间单位不同的情况下来说，HARQ码本是错误的，影响了接入网设备和终端之间的数据传输。

具体实施方式
本申请提供了HARQ码本的生成方法及相关设备，使得载波聚合的成员载波中具有不同传输时间单元长度的载波时，可以正确的生成HARQ码本，不影响接入网设备和终端之间的数据传输。
下面将结合本申请中的附图，对本申请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。
首先简单介绍本发明应用的系统构架或场景。
本发明可以用于但不限于LTE系统及其演进的系统中，也可以用于5G技术中，系统构架如图1所示，接入网设备和接入网设备之间及接入网设备和终端之间均可传输数据，终 端想要接入网络时，可以通过向接入网设备发送接入请求，接入网设备为终端分配配置的载波，使得终端可与接入网设备进行数据传输，为满足不同业务类型对于载波参数的需求，在LTE-Advanced中，3GPP提出了载波聚合技术，它很好地将多个载波聚合成一个更宽的频谱，同时也可以把一些不连续的频谱聚合到一起。现有的被聚合的载波使用的传输时间单位都相同，都为1ms，现有的HARQ码本可以是通过配置的载波数确定HARQ码本或者通过调度的载波数确定HARQ码本，配置的载波指的是在终端接入接入网设备时，接入网设备为终端配置的终端能够使用的载波，每一个载波的状态可以是激活状态或者未激活状态；激活状态的载波指的是一个载波处于激活状态，终端可以使用该载波来传输数据；调度的载波指的是终端实际用来传输数据的载波。
在LTE-Advanced中，可以将配置的载波分为1个或2个Cell Group，每个Cell Group中有1个载波可以进行物理上行控制信道(Physical Uplink Control Channel，PUCCH)传输，比如主载波(Primary Serving Cell，Pcell)，该Pcell需要联合反馈Cell Group中其它载波的HARQ信息。例如，接入网设备为终端配置了5个载波，编号从0到4，载波0为Pcell，其它4个载波为辅载波(Secondary Serving Cell，Scell)，5个载波都为时分双工(Time Division Duplexing，TDD)载波，并且配比相同。在Pcell的某个上行子帧上，需要确定反馈的HARQ码本，如图2所示，D0、D4和D5为下行子帧，S1和S6为特殊子帧，U2、U3、U7和U8为上行子帧，在子帧7(U7)上，需要反馈的时间窗为子帧0(D0)和子帧1(S1)，而终端只在Pcell的子帧0上正确接收数据，并且在其他辅载波上未正确接收数据，则反馈的HARQ码本为1000000000，其中HARQ码本中的10为Pcell上的HARQ反馈信息，HARQ反馈信息表示的是终端对于子帧0和子帧1上承载数据的接收情况，1表示终端正确接收数据，0表示终端未正确接收数据；HARQ码本中后面的8位0，则是4个Scell中对应于子帧7的子帧中HARQ反馈信息，可见HARQ码本的码本大小为10个bit。
但是，在本发明中LTE或者5G技术中，聚合载波中的第一载波(即现有技术的Pcell)和第二载波((即现有技术的Scell)的传输时间单元的长度并不是一致的，传输时间单元可以是现有技术中的子帧，也可以是时隙等，由于第一载波和第二载波的传输时间单元的长度并不相等，那么的按照上述所述的方式是得到的HARQ码本大小是不准确的，因此需要重新设置HARQ码本的生成方式。
下面对本申请中涉及的几个术语做一些解释：HARQ反馈信息表示的是终端对于传输时间单元中承载的数据的数据接收情况，接收情况可以为正确接收或错误接收，时间窗表示的是需要反馈的传输时间单元的集合，例如，一个传输时间单元要反馈2个传输时间单元的数据接收情况，且接入网设备和终端之间的数据传输使用1个传输块(Transmit Block,TB),则该传输时间单元的时间窗大小为2bit，HARQ定时表示终端在传输时间单元u之后的第i个传输时间单元反馈传输时间单元u的数据接收情况。HARQ码本表示的是接入网设备向终端下发数据时，终端对于数据的接收情况，接入网设备根据HARQ码本可以知道终端的数据接收情况，从而调整与终端之间的信道、发射功率或编码方式等等，使得接入网设备与终端之间的数据传输条件可以满足通信标准。
终端综合时间窗、HARQ反馈信息或HARQ定时就可以生成HARQ码本，
下面通过接入网设备和终端之间的交互对HARQ码本的生成方法进行说明，请参阅图3， 本发明实施例提供一种HARQ码本的生成方法，包括：
301、接入网设备为终端分配配置的载波；
本实施例中，接入网设备在终端接入时，需要为终端分配终端可以使用的载波，即分配配置的载波，配置的载波包括第一载波和第二载波，第一载波的HARQ反馈信息和第二载波的HARQ反馈信息在第一载波上的上行控制信道进行反馈，即第一载波相当于现有技术中的Pcell，而第二载波相当于现有技术中的Scell，其中，第一载波的传输时间单元长度与第二载波的传输时间单元长度不相等。
第一载波的传输时间单元长度与第二载波的传输时间单元长度不相等可以是由于第一载波和第二载波对应的参数集合(还可以称为numerology)不同导致的，也可以是由于第一载波和第二载波的子载波间隔不同所导致的。302、接入网设备根据分配生成第一信息；
本实施例中，接入网设备根据上述的配置的载波的分配情况生成第一信息，第一信息可以包含向终端发送的消息中，该消息具体可以是系统消息的系统信息块(System Information Block，SIB)中，现有的SIB的种类有上十种，每一种SIB都具有不同的用途，比如SIB2用于小区更新或小区切换等，可以在现有的特定SIB中包含第一信息，也可以生成新的SIB用于包含第一信息，第一信息用于向终端指示接入网设备为终端配置的载波，配置的载波包括第一载波和第二载波，第一载波的HARQ反馈信息和第二载波的HARQ反馈信息在第一载波的上行控制信道上传输，其中，第一载波的传输时间单元长度与第二载波的传输时间单元长度不相等，需要说明的是，如果配置的载波的HARQ定时是接入网设备实时设置的，那么可以将配置的载波的HARQ定时也通过第一信息指示，或者通过与第一信息所包含在不同消息中的不同的第二信息指示给终端。如果配置的载波的HARQ定时是接入网设备和终端之间预先约定，那么不需要包含在第一信息中。
303、接入网设备并将第一信息发送至终端，终端接收接入网设备发送的第一信息；
本实施例中，为了能够使得终端和接入网设备之间传输数据，接入网设备需要将第一信息发送至终端，具体发送时，第一信息还可以包含在消息中，终端接收接入网设备发送的该信息，从该消息中得到第一信息。
304、终端根据配置的载波的HARQ定时、第一载波的传输时间单元长度和第二载波的传输时间单元长度之间的关系，生成在第一载波的上行控制信道上传输的HARQ码本。
本实施例中，终端从接收到的第一信息中可以得到第一载波的传输时间单元长度和第二载波的传输时间单元长度之间的关系，或者从与第一信息所包含在不同消息中的不同的第三信息中得到。如果配置的载波的HARQ定时是接入网设备实时设置的，那么根据第一信息可以得到配置的载波的HARQ定时，或者，根据接入网设备和终端之间预先约定可以知道配置的载波的HARQ定时，根据配置的载波的HARQ定时、第一载波的传输时间单元长度和第二载波的传输时间单元长度之间的关系，可以确定第一载波的HARQ反馈信息和第二载波的HARQ反馈信息，根据第一载波的HARQ反馈信息和第二载波的HARQ反馈信息生成在第一载波的上行控制信道上传输的HARQ码本。
本发明实施例中，由于终端是根据接入网设备配置的载波的HARQ定时、第一载波的传输时间单元长度和第二载波的传输时间单元长度之间的关系，生成在第一载波的上行控制信道上传输的HARQ码本，第一载波的传输时间单元长度和第二载波的传输时间单元长度不 相等，如果还是采用现有的HARQ码本生成方式，终端生成的HARQ码本将会是错误的，本发明实施例可以使得终端正确的生成HARQ码本，不影响接入网设备和终端之间的数据传输。
上述实施例中只限定了第一载波的传输时间单元长度和第二载波的传输时间单元长度不相等，具体的第一载波的传输时间单元长度和第二载波的传输时间单元长度之间的关系的不同，可能会影响到HARQ码本的生成，下面通过实施例对不同的第一载波的传输时间单元长度和第二载波的传输时间单元长度之间的关系下，HARQ码本的生成进行具体说明。
可选的，本发明的一些实施例中，第一载波的传输时间单元长度和第二载波的传输时间单元长度之间的关系为：第一载波的传输时间单元长度为第二载波中的传输时间单元长度的N倍；一个第一载波的传输时间单元n与N个第二载波的传输时间单元在时域上对齐，N个第二载波的传输时间单元中包括传输时间单元m；其中，N为大于1的正整数，n和m为自然数；
配置的载波的HARQ定时包括第二载波的传输时间单元m的HARQ定时，用于指示终端在第一载波的传输时间单元n后的第k个传输时间单元上传输传输时间单元m的HARQ反馈信息；
终端根据配置的载波的HARQ定时、第一载波的传输时间单元长度和第二载波的传输时间单元长度之间的关系，生成在第一载波的上行控制信道上传输的HARQ码本，包括：
终端生成在第一载波的传输时间单元n后的第k个传输时间单元上传输的HARQ码本；其中，HARQ码本中所包括的第二载波的HARQ码本大小为N倍的第二载波的时间窗大小，时间窗大小为需要在一个上行传输时间单元上传输HARQ反馈信息的下行传输时间单元的个数。
本发明实施例中，具体可以如图4所示，第一载波的传输时间单元长度为第二载波中的传输时间单元长度的4倍；一个第一载波的传输时间单元与4个第二载波的传输时间单元在时域上对齐，与第一载波的传输时间单元0对应的4个第二载波的传输时间单元中包括第二载波的下行传输时间单元1和3，与第一载波的传输时间单元1对应的4个第二载波的传输时间单元中包括第二载波的下行传输时间单元5，第一载波的HARQ定时的设置与现有技术中的一致，图4中在第一载波的传输时间单元2传输第一载波的传输时间单元0的HARQ反馈信息和第一载波的传输时间单元1的HARQ反馈信息，而第二载波的传输时间单元1和3的HARQ定时用于指示终端在第一载波的传输时间单元2上传输第二载波的传输时间单元1和3的HARQ反馈信息，而第二载波的传输时间单元5的HARQ定时用于指示终端在第一载波的传输时间单元2上传输第二载波的传输时间单元5的HARQ反馈信息，终端生成在第一载波的传输时间单元2的HARQ码本，HARQ码本中所包括的第一载波的HARQ码本大小为2位bit，第一载波的时间窗大小与HARQ码本大小相同为2位bit，由于第二载波上的4个传输时间单元与第一载波的一个传输时间单元对齐，第二载波的时间窗大小也为2位bit，而第二载波的HARQ码本大小为4倍的第二载波的时间窗大小，即8位bit，假设第一载波的传输时间单元0的数据接收正确，而第一载波的传输时间单元1的数据接收错误，那么第一载波的HARQ反馈信息为10，假设第二载波的传输时间单元1、3和5的数据接收正确，那么第二载波的HARQ反馈信息为01010100，将第一载波和第二载波的HARQ 反馈信息进行级联得到的HARQ码本为1001010100，需要说明的是，本方案中的级联方式得到的HARQ码本中第一载波的HARQ反馈信息处于前端，如“10”，第二载波的HARQ反馈信息处于第一载波的HARQ反馈信息之后，如“01010100”。在实际实施中，级联方式也可以是第二载波的HARQ反馈信息处于前端，第一载波的HARQ反馈信息处于第二载波的HARQ反馈信息之后，HARQ码本为“0101010010”。除此之外，具体的级联方式还可以是其他形式，不做限定。
需要说明的是，在图4中只选择了传输时间单元长度为1/4的第一载波的传输时间单元长度的第二载波，在具体实施时，还可以有其他传输时间单元长度的载波。这些具有其他传输单元长度的载波也同样需要在第一载波上传输HARQ反馈信息，终端只需采用和第二载波相同的处理方式生成需要在所述第一载波上反馈的码本，再和其它同样需要在第一载波上反馈的码本进行级联即可。
为了方便表述，第二载波的时间窗大小可以记作W，那么第二载波的HARQ码本大小为记作W乘以N(W*N)。
在该实施例的一些具体实现方式中，为了避免过大的反馈开销，接入网设备还可以配置一个最大值U，即第二载波的HARQ码本大小为U和W*N中的较小值，记作min(W*N,U)。当W*N>U时，第二载波的HARQ码本大小为U。可选地，若检测到调度的物理下行共享信道(physical downlink shared channel，PDSCH)的个数超过了U，则仅反馈最先检测到的U个PDSCH的HARQ反馈信息；或者,仅反馈由携带DAI值小于U的下行控制信息(downlink control information，DCI)调度的PDSCH的HARQ反馈信息。可选的，每个载波配置一个U值；或者所有载波共用1个U值。
另外，一个时间窗内，第二载波中可能存在一些传输时间单元为高层信令,比如无线资源控制协议(radio resource control，RRC)信令或者系统信息块(system information block，SIB)等,配置的上行传输时间单元，这些传输时间单元没有下行数据传输，故而不需要终端反馈信息，可以配置第二载波的HARQ码本大小为W*N-X，其中X为一个第二载波时间窗内通过高层信令配置为上行传输时间单元的个数。
在上述实施例中，物理下行控制信道(physical downlink control channel，PDCCH)(用于调度PDSCH的DCI或者所在的资源集合)的监测周期为1个传输时间单元。在本实施例的另一些具体实现方式中，PDCCH的监测周期可配置为T，T≥1，且T为整数。基于上述实施例，此时，第二载波的HARQ码本大小为min(W*N/T,U)。若W*N不能被T整除，则可以对W*N/T向上取整，或者对W*N/T向下取整，即，第二载波的HARQ码本大小为
Figure PCTCN2017108077-appb-000001
或者
Figure PCTCN2017108077-appb-000002
采用向上取整还是向下取整可以由PDCCH的监测起始传输时间单元(或者偏移)确定。
本领域的技术人员可以将上述描述的各个实施例进行结合，即综合考虑上述各种因素中的一种或者多种来生成反馈的码本，在这里不做任何限制。
上述实施例是基于第一载波的传输时间单元长度为粒度定义和/或者配置的反馈窗。例 如，以第一载波的传输时间单元长度为粒度定义或者配置的反馈窗为{n+1,n+2}，意味着图4中的第一载波上时间单元0(对应n+2)和时间单元1(对应n+1)可以在时间单元2上反馈,因此第一载波的码本大小为2；图4中的第二载波上时间单元0(对应n+2)、时间单元1(对应n+2)，时间单元2(对应n+2)、时间单元3(对应n+2)，时间单元4(对应n+1)、时间单元5(对应n+1)，时间单元6(对应n+1)、时间单元7(对应n+1)可以在第一载波时间单元2上反馈,因此第一载波的码本大小为8。又例如，如图4所示，对于第一载波，PDSCH在第一载波传输时间单元n＝0上传输，其HARQ反馈信息可以在第一载波传输时间单元n+2(即第一载波传输时间单元2)上反馈；对于第二载波，PDSCH在第二载波传输时间单元m＝1上传输，对应第一载波的传输时间单元为n＝0。其HARQ反馈信息可以在第一载波传输时间单元n+2(即第一载波传输时间单元2)上反馈。其中时间单元粒度为第一载波的传输时间单元，因此第二载波的HARQ码本大小根据W*N确定。
此外，还可以基于第二载波的传输时间单元长度的粒度定义或者配置时间窗(各载波的时间窗是基于自身的传输时间单元长度粒度定义和/或配置)，即这样，以第二载波的传输时间单元长度为粒度定义或者配置的第二载波反馈窗为{n+1,n+2}，意味着图4中的第二载波上时间单元6(对应n+2)、时间单元7(对应n+1)可以在第一载波时间单元2上反馈,因此第一载波的码本大小为2。此时，第二载波的HARQ码本大小为W；与上述实施例类似，若考虑额外引入配置最大值U，则第二载波的HARQ码本大小为min(W,U)；若额外考虑PDCCH监测周期，则第二载波的HARQ码本大小为min(W/T,U)，或者

或者

可选的，本发明的一些实施例中，第一载波的传输时间单元长度和第二载波的传输时间单元长度之间的关系为：第一载波的传输时间单元长度为第二载波的传输时间单元长度的N倍；一个第一载波的传输时间单元n与N个第二载波传输的时间单元在时域对齐，N为大于1的正整数，n为自然数；
配置的载波的HARQ定时包括第二载波的HARQ定时，用于指示终端在第二载波的N个传输时间单元中的至少一个上传输HARQ反馈信息；
终端根据配置的载波的HARQ定时、第一载波的传输时间单元长度和第二载波的传输时间单元长度之间的关系，生成在第一载波的上行控制信道上传输的HARQ码本，包括：
终端根据第二载波的HARQ定时，确定在第一载波上的传输时间单元n上传输需要在N个传输时间单元中的至少一个上传输的HARQ反馈信息；
终端生成在第一载波上的传输时间单元n上传输的HARQ码本，其中，HARQ码本中所包括的第二载波的HARQ码本大小为N倍的第二载波的时间窗大小，时间窗大小为需要在一个上行传输时间单元上传输HARQ反馈信息的下行传输时间单元的个数。
本发明实施例中，如图5所示，第一载波的传输时间单元长度为第二载波中的传输时间单元长度的4倍；一个第一载波的传输时间单元与4个第二载波的传输时间单元在时域上对齐，与第一载波的传输时间单元0对应的4个第二载波的传输时间单元中包括第二载波的下行传输时间单元0、1和2，第一载波的HARQ定时的设置与现有技术中的一致，图5 中在第一载波的传输时间单元1传输第一载波的传输时间单元0的HARQ反馈信息，而第二载波的传输时间单元0的HARQ定时用于指示终端在第二载波的传输时间单元4传输传输时间单元0的HARQ反馈信息，并且终端会将传输时间单元4中的HARQ反馈信息对应到第一载波的传输时间单元1上；第二载波的传输时间单元1的HARQ定时用于指示终端在第二载波的传输时间单元6传输时间单元1的HARQ反馈信息，并且终端会将传输时间单元6中的HARQ反馈信息对应到第一载波的传输时间单元1上；第二载波的传输时间单元2的HARQ定时用于指示终端在第二载波的传输时间单元7传输传输时间单元2的HARQ反馈信息，并且终端会将传输时间单元7中的HARQ反馈信息对应到第一载波的传输时间单元1上。终端生成在第一载波的传输时间单元1的HARQ码本，第一载波和第二载波的时间窗大小都为1位bit，HARQ码本中所包括的第一载波的HARQ码本大小为1位bit，第二载波的HARQ码本大小为4倍第二载波的时间窗大小，假设第一载波的传输时间单元0的数据接收正确，那么第一载波的HARQ反馈信息为1，假设第二载波的传输时间单元0和1的数据接收正确，传输时间单元2的数据接收错误，那么第二载波的HARQ反馈信息为1100，将第一载波和第二载波的HARQ反馈信息进行级联得到的第一载波的传输时间单元1的HARQ码本为11100。
在图5所示的实施例中第二载波的HARQ码本大小是N倍第二载波的时间窗大小，而另一种第二载波的HARQ码本大小是M个第二载波的上行传输时间单元的时间窗大小，具体如下：
可选的，本发明的一些实施例中，第一载波的传输时间单元长度和第二载波的传输时间单元长度之间的关系为：第一载波的传输时间单元长度为第二载波的传输时间单元长度的N倍；一个第一载波的传输时间单元n与N个第二载波传输的时间单元在时域对齐，N个第二载波的传输时间单元中包括M个上行传输时间单元，N为大于1的正整数，M为正整数，n为自然数，M≤N，
配置的载波的HARQ定时包括第二载波的HARQ定时，用于指示终端在第二载波的M个上行传输时间单元中的至少一个上传输HARQ反馈信息；
终端根据配置的载波的HARQ定时、第一载波的传输时间单元长度和第二载波的传输时间单元长度之间的关系，生成在第一载波的上行控制信道上传输的HARQ码本，包括：
终端生成在第一载波上的传输时间单元n上传输的HARQ码本，其中，HARQ码本中所包括的第二载波的HARQ码本大小为M倍的第二载波的时间窗大小，时间窗大小为需要在一个上行传输时间单元上传输HARQ反馈信息的下行传输时间单元的个数。
本发明实施例中，基于如图5所示的分配配置的载波，第一载波和第二载波的时间窗大小都为1位bit，HARQ码本中所包括的第一载波的HARQ码本大小为1位bit，由于第二载波的传输时间单元4-7中包括3个上行传输时间单元(传输时间单元4、6和7)，那么第二载波的HARQ码本大小为3倍第二载波的时间窗大小，假设第一载波的传输时间单元0的数据接收正确，那么第一载波的HARQ反馈信息为1，假设第二载波的传输时间单元0和1的数据接收正确，传输时间单元2的数据接收错误，那么第二载波的HARQ反馈信息为110，将第一载波和第二载波的HARQ反馈信息进行级联得到的第一载波的传输时间单元1的HARQ码本为1110。
上述实施例中描述的是第一载波的传输时间单元长度为第二载波的传输时间单元长度的N倍，下面具体说明第二载波的传输时间单元长度为第一载波的传输时间单元长度的N倍的情况。
可选的，本发明的一些实施例中，第一载波的传输时间单元长度和第二载波的传输时间单元长度之间的关系为：第二载波的传输时间单元长度为第一载波的传输时间单元长度的N倍，N个第一载波的传输时间单元与一个第二载波的传输时间单元n在时域上对齐，N个第一载波的传输时间单元中在时域上的最后一个传输时间单元为传输时间单元m，N为大于1的正整数，n，m为自然数，
配置的载波的HARQ定时包括第二载波的传输时间单元n上的HARQ定时，用于指示终端在第一载波的传输时间单元m后的第k个传输时间单元上传输传输时间单元n的HARQ反馈信息；
终端根据配置的载波的HARQ定时、第一载波的传输时间单元长度和第二载波的传输时间单元长度之间的关系，生成在第一载波的上行控制信道上传输的HARQ码本，包括：
终端生成在第一载波的传输时间单元m后的第k个传输时间单元上进行HARQ反馈信息反馈的HARQ码本；其中，HARQ码本中所包括的第二载波的HARQ码本大小为1/N倍的第二载波的时间窗大小，或等于第一载波的时间窗大小，时间窗大小为需要在一个上行传输时间单元上传输HARQ反馈信息的下行传输时间单元的个数。
本发明实施例中，如图6所示，第二载波的传输时间单元长度为第一载波中的传输时间单元长度的2倍；一个第二载波的传输时间单元与2个第一载波的传输时间单元在时域上对齐，与第一载波的传输时间单元0和1对齐的第二载波的传输时间单元0为下行传输时间单元，第一载波的传输时间单元2和3对齐的第二载波的传输时间单元1为下行传输时间单元，第二载波的传输时间单元0的HARQ定时用于指示终端在第一载波的传输时间单元4传输第二载波的传输时间单元0的HARQ反馈信息，第二载波的传输时间单元1的HARQ定时用于指示终端在第一载波的传输时间单元5传输第二载波的传输时间单元1的HARQ反馈信息，由于第一载波的传输时间单元4和5需要反馈两个传输时间单元(第二载波的传输时间单元0和1)的HARQ反馈信息，那么当第二载波的时间窗大小为2位bit，HARQ码本中所包括的第二载波的HARQ码本大小为1/2个第二载波的时间窗大小，即第二载波的HARQ码本大小为1位bit，假设第二载波的传输时间单元0和1的数据接收正确，在第一载波的传输时间单元4和5上的第二载波的HARQ码本都为1，而第一载波的HARQ码本的生成方式与上述实施例中一致，而且第一载波的HARQ码本和HARQ码本级联得到第一载波的上行控制信道的HARQ码的方式也是采用级联的方式。
可选的，本发明的一些实施例中，第一载波的传输时间单元长度和第二载波的传输时间单元长度之间的关系为：第二载波的传输时间单元长度为第一载波的传输时间单元长度的N倍，N个第一载波的传输时间单元与一个第二载波的传输时间单元n在时域上对齐，且N个第一载波的传输时间单元中包括M个上行传输时间单元，N为大于1的正整数，n，m为自然数，M≤N，
配置的载波的HARQ定时包括第二载波的HARQ定时，用于指示终端在第二载波的传输时间单元n上传输HARQ反馈信息；
终端根据配置的载波的HARQ定时、第一载波的传输时间单元长度和第二载波的传输时间单元长度之间的关系，生成在第一载波的上行控制信道上传输的HARQ码本，包括：
终端根据第二载波的HARQ定时，确定在第一载波上的M个传输时间单元之一传输需要在第二载波的传输时间单元n上传输HARQ反馈信息；
终端生成在第一载波上的M个传输时间单元之一的HARQ码本，其中，HARQ码本中所包括的第二载波的HARQ码本大小为1/M倍的第二载波的时间窗大小，时间窗大小为一个上行传输时间单元需要反馈的下行传输时间单元的个数。
本发明实施例中，如图7所示，第二载波的传输时间单元长度为第一载波中的传输时间单元长度的2倍；一个第二载波的传输时间单元与2个第一载波的传输时间单元在时域上对齐，与第一载波的传输时间单元0和1对齐的第二载波的传输时间单元0为下行传输时间单元，第一载波的传输时间单元2和3对齐的第二载波的传输时间单元1为下行传输时间单元，第一载波的传输时间单元4和5对齐的第二载波的传输时间单元2为上行传输时间单元，两个个第一载波的传输时间单元4和5中均为上行传输时间单元，第二载波的传输时间单元0的HARQ定时用于指示终端在第二载波的传输时间单元2传输第二载波的传输时间单元0的HARQ反馈信息，第二载波的传输时间单元1的HARQ定时用于指示终端在第二载波的传输时间单元2传输第二载波的传输时间单元1的HARQ反馈信息，第二载波的传输时间单元2需要反馈传输时间单元0和1的HARQ反馈信息，那么第二载波的时间窗大小可以为2为bit。第二载波的传输时间单元2中的HARQ反馈信息实际上是需要在第一载波上对应的传输时间单元4和5上传输的，可以采取先后及均分的原则，第二载波的传输时间单元0的HARQ反馈信息在第一载波的传输时间单元4上传输，第二载波的传输时间单元1的HARQ反馈信息在第一载波的传输时间单元5上传输。因此，HARQ码本中所包括的第二载波的HARQ码本大小为1/2个第二载波的时间窗大小，第二载波的HARQ码本大小为1位bit，假设第二载波的传输时间单元0的数据接收正确，第二载波的HARQ码本为1，而第一载波的HARQ码本的生成方式与上述实施例中一致，而且第一载波的HARQ码本和HARQ码本级联得到第一载波的上行控制信道的HARQ码的方式也是采用级联的方式，不做具体的说明。
或者，也可以将第二载波的传输时间单元0和1上的反馈信息全都在第一载波的传输时间单元4或者5进行反馈。
也即，1个第二载波传输时间单元与N个第一载波的传输时间单元对齐时，在所述N个第一载波的传输时间单元中第一个上行传输时间单元传输HARQ反馈信息，或者终端预先知道所述N个第一载波的传输时间单元的传输方向：其中，有N1个是上行传输时间单元，终端可以将第二载波的码本均分为N1份分别在所述N1个上行传输时间单元进行反馈。
应理解的是，半静态码本大小除了受载波数和时间窗大小影响外，还受码字数和CBG(code block group)个数相关。以上实施例都是假设单码字传输并且没有开启CBG反馈模式的情况。若某个载波上的时间窗内存在至少1个2码字传输且不采用混合自动重传请求-确认回答捆绑(HARQ-ACK bundling)方式，则半静态码本下该载波对应的反馈比特数 为还需在上述实施例基础上乘以2。当网络设备通过RRC信令为终端设备在某个载波上配置了CBG级传输和CBG反馈，且配置最大CBG个数为N时，半静态码本中该载波的HARQ-ACK信息比特数需要在上面得到的大小基础上乘以N。各TB对应位置的N比特中前M比特对应该TB的各CBG的HARQ-ACK信息，后N-M可以为默认的NACK。
除了上述实施例之外，终端还可以根据DAI信息生成HARQ码本进行详细说明，具体如下:
接入网设备根据至少两种传输时间单元长度中最短的传输时间单元长度，确定总DAI的值和累计DAI的值；
接入网设备将总DAI的值和累计DAI的值发送给终端，终端接收接入网设备发送的总DAI的值和累计DAI的值；
终端根据总DAI的值和累计DAI的值确定HARQ码本。
可选的，本发明的一些实施例中，多载波中包括的最长的传输时间单元长度为最短的传输时间单元长度的N倍，即N个最短的传输时间单元与一个最长的传输时间单元在时域上对齐，
接入网设备根据至少两种传输时间单元长度中最小的传输时间单元长度，确定总DAI的值和累计DAI的值，包括：
若多载波中第一载波上存在第一传输时间单元的头部与N个最短的传输时间单元中一个的头部在时域上对齐，且第一载波在所述第一传输时间单元持续的时间内被调度，则将第一载波计算入总DAI和累计DAI中。
本发明实施例中，如下表1，终端生成HARQ码本的具体方式如下：
载波0到载波2的传输时间单元长度为0.5ms，载波3到载波6的传输时间单元长度为0.25ms，载波7到载波10的传输时间单元长度为0.125ms，表1中显示与载波7到载波10的最小长度的传输时间单元0对齐的载波0到载波2中调度载波有载波0和载波2，载波3到载波6中调度载波有载波4和载波6，载波7到载波10中调度载波有载波8；与载波7到载波10的最小长度的传输时间单元1对齐的载波7到载波10中调度载波有载波7和载波9；与载波7到载波10的最小长度的传输时间单元2对齐的载波3到载波6中调度载波有载波3，与载波7到载波10的最小长度的传输时间单元2对齐的载波7到载波10中调度载波有载波8和载波10；与载波7到载波10的最小长度的传输时间单元4对齐的载波7到载波10中调度载波有载波8和载波9，终端根据接入网设备配置的表1的调度载波信息，接入网设备可以以最小传输时间单元0.125ms为统计单位，在第一个0.125ms传输时间单元时，与该子帧对齐的其它子帧中共有5个载波被调度，则该5个被调度的载波的总DAI的值为5，累计DAI的值为1、2、3、4或5，以载波编号从低到高计算。在二个0.125ms传输时间单元时，与该传输时间单元头部对齐的其它传输时间单元只有两个载波被调度，则总DAI的值为7，累计DAI的值为6或7；在第三个0.125ms传输时间单元时，与该传输时间单元头部对齐的其它传输时间单元只有3个载波被调度，则总DAI的值为10，累计DAI的值为8、9或10，在第四个0.125ms传输时间单元时，与该传输时间单元头部对齐的其它传输时间单元只有2个载波被调度，则总DAI的值为12，累计DAI的值为11 或12，得到的HARQ码本大小为12位bit，而根据每一个调度载波的传输时间单元中数据接收状况可以得到HARQ码本。
