Description

混合自动重传请求反馈的传输方法、装置及存储介质 技术领域
本申请涉及无线通信技术领域但不限于无线通信技术领域，尤其涉及一种混合自动重传请求反馈的传输方法、装置及存储介质。
背景技术
机器类通信技术(MTC，Machine Type Communication)是蜂窝物联网技术的典型代表。目前，MTC已经广泛用于智慧城市，例如抄表；智慧农业，例如温度湿度等信息的采集；智慧交通，例如共享单车等诸多领域。
MTC在多传输块(TB，Transmission Block)交替传输调度中，多个TB的传输互相交错，若有TB传输不成功时，会发送混合自动重传请求(HARQ，Hybrid Automatic Repeat reQuest)反馈，但是针对MTC终端等设备在HARQ反馈的发送过程中出现异常，导致HARQ反馈发送失败率高的问题。
为减少HARQ反馈失败率高的问题，也可以由基站对HARQ反馈传输方式进行配置；频繁进行基站配置，会造成通信流程复杂，浪费信令开销的问题。

请参考图1，其示出了本公开实施例提供的一种无线通信***的结构示意图。如图1所示，无线通信***是基于蜂窝移动通信技术的通信***，该无线通信***可以包括：若干个终端11以及若干个基站12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网 进行通信，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、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)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment，UE)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信***中的网络侧设备。其中，该无线通信***可以是***移动通信技术(the 4th generation mobile communication，4G)***，又称长期演进(Long Term Evolution，LTE)***；或者，该无线通信***也可以是5G***，又称新空口(new radio，NR)***或5G NR***。或者，该无线通信***也可以是5G***的再下一代***。其中，5G***中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC***。
其中，基站12可以是4G***中采用的演进型基站(eNB)。或者，基站12也可以是5G***中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实 施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于***移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，终端11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信***还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信***中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
本公开实施例涉及的执行主体包括但不限于：采用MTC进行通信传输的设备，如MTC终端、物联网终端等MTC用户端。
本公开实施例的应用场景为，针对MTC的信号覆盖弱，MTC设备相对低造价和低处理能力等状况，MTC在多TB调度中使用了TB交替传输的机制，即交替重复传输不同TB，图2为对一个序列的TB进行交替重复 传输。
采用TB交替传输的方式，每个TB传输结束的时间比较接近，按照相关MTC中采用的传输HARQ反馈的方式，如图3所示，会导致针对任意TB中多个的HARQ反馈在时间上重叠，从而增加发送HARQ反馈的设备，即MTC用户端处理HARQ反馈的复杂程度，由于发送HARQ反馈的设备的性能限制，甚至引起发送HARQ反馈的设备无法工作。其中，P1至P4分别表示TB1至TB4是HARQ反馈，多个P1至P4表示P1至P4被重复传输多次。
可以对HARQ反馈传输进行配置来较少HARQ反馈在时间上重叠，但是HARQ反馈在时间上重叠的概率很大，每次都需要进行基站配置的话，会造成整个通信流程复杂，并且浪费信令开销。
如图4所示，本示例性实施例提供一种HARQ反馈的传输方法，HARQ反馈的传输方法可以用于终端等无线通信设备中，包括：
当满足预设条件时，针对多传输块TB调度传输，使用HARQ反馈的目标传输方式传输HARQ反馈，其中，所述使用HARQ反馈的目标传输方式传输HARQ反馈，包括：对接收的任意TB中多个的HARQ反馈进行编码，生成并传输HARQ反馈信息。
所述多TB调度传输为采用一个下行控制信道PDCCH资源传输多个TB。
在一些实施例中，所述交替传输TB包括：循环传输TB交替传输单元直至满足每个所述TB被配置的总重复传输次数，其中所述TB交替传输单元包含不同TB的N次重复传输，N为大于0并且小于M，M为所述总重复传输次数。
这里，所述终端可以是MTC用户端；一个TB交替传输单元包括：至少两个TB，这些TB按照一定的顺序进行排序，形成一个TB交替传输单 元。
其中，这里的TB是一种内容块；不同的TB包含的数据内容不同。如图2所示，一个TB的总重复传输次数为4，在一个TB交替传输单元中，一个TB被重复传输N次，图2中N为2。4次总重复传输的TB1中的数据内容相同，TB1和TB2中包含的数据内容不同。4次传输的TB1的内容相同。通过交替传输，可以实现同一个TB的接收功率的累加，从而增加快TB的接收端的解码成功率。
HARQ反馈发送端如MTC用户端可以预先设置HARQ反馈的传输方式规则；HARQ反馈的传输方式规则用于定义预设条件和HARQ反馈的目标传输方式。
HARQ反馈发送端如MTC用户端，接收多个TB后，对TB进行解调和解码，并确认TB是否解码成功，然后将各TB的HARQ反馈通过编码得到一个HARQ反馈信息，并发送该HARQ反馈信息，可以减少HARQ反馈在时间上重叠的情况，减HARQ反馈发送端处理HARQ反馈的复杂度，降低对HARQ反馈发送端的性能需求，进而提升HARQ反馈信息发送成功率，提高HARQ反馈发送端稳定性。这里，一个HARD反馈可以用一个时域资源进行传输。
将任意TB中多个的HARQ反馈编码生成HARQ反馈信息再进行传输的方式可以称为绑定传输。生成的HARQ反馈信息可以反应多个不同TB的解调状况。
MTC用户端的HARQ反馈的传输方式规则可以和基站的HARQ反馈的接收方式规则向对应，确保MTC用户端发送HARQ反馈信息时，基站采用对应的接收HARQ反馈信息的方式接收。
如此，当满足预设条件时，基站不需要额外的信令对MTC用户端的HARQ反馈传输方式进行配置，而是根据预先设置HARQ反馈的传输方式 规则进行处理，简化配置流程，节约信令开销。
在一些实施例中，一个TB具有一个HARQ反馈。
当然在另一些实施例中，多次重复传输的TB可具有多个HARQ反馈。若一个TB具有一个HARQ反馈，如此减少了不必要的HARQ反馈所占用的传输资源，节省了传输开销。
如图2所示的TB交替传输中，TB交替传输单元被传输两次，一个TB在一个TB交替传输单元中重复传输两次。重复传输的一个TB中的数据内容相同，如4次传输的TB1中的数据内容相同。
在交替传输中，一个TB会被交替重复传输多次，HARQ反馈发送端接收到多次传输的该TB后，会将多次接收到的该TB一起进行解调；解调结果通过HARQ反馈传输回TB发送端；HARQ反馈包括：ACK和NACK等。
具体地如，如果解调结果正确则反馈ACK，和/或，如果解调结果不正确则反馈NACK。
如图2所示，TB1在交替重复传输中共被传输4次，HARQ反馈发送端解析4次重复传输的TB1后会向基站发送一个HARQ反馈以反馈TB1是否被正确解调。图2所示的TB1至TB4的交替传输中，HARQ反馈发送端会向基站传输TB1至TB4各自分别对应的共4个HARQ反馈。
这里，可以将任意TB中多个的HARQ反馈进行预定编码，得到由多个HARQ反馈编码而成的HARQ反馈信息；HARQ反馈信息内容由可以根据预定编码确定，可以反应出多个TB的解调结果信息，如可以整体反馈反应出是否多个TB均被正确解调。
HARQ反馈信息可以是一个，从而在传输HARQ反馈信息过程中，可以减少任意TB中多个的HARQ反馈在时间上重叠的情况，减小HARQ反馈发送端处理HARQ反馈的复杂度，减缓HARQ反馈发送端的工作负担， 提高HARQ反馈发送端稳定性。
在一些实施例中，所述预设条件，包括：接收的TB的传输配置信息指示允许交替传输TB。
当MTC用户端被配置允许使用交替传输时，则MTC用户端默认采用将任意TB中多个的HARQ反馈编码生成HARQ反馈信息再进行传输。此时基站侧默认采用接收HARQ反馈信息的方式进行接收。
这里，确定所述传输配置信息确定允许交替传输TB的方式可以是：如果TB的传输配置信息中包含交替传输配置信息或其他预定信息，则确定允许交替传输TB。HARQ反馈对应的TB，可以是交替传输的TB，也可以是采用常用方式进行传输的TB。
如此，当所述传输配置信息确定允许交替传输TB时，说明有出现交替传输TB的可能，基站不需要额外的信令对MTC用户端的HARQ反馈传输方式进行配置，而是根据预先设置HARQ反馈的传输方式规则进行处理，简化配置流程，节约信令开销。
在一些实施例中，所述预设条件，包括：接收的TB的传输配置信息指示允许交替传输TB，并且激活了交替传输TB方式。
在一些实施例中，所述激活了交替传输TB方式，包括：确定在当前TB调度传输中使用所述交替传输TB方式。
这里，预先设置HARQ反馈的传输方式规则可以将预设条件设为只有当交替传输TB方式被激活时，即TB采用交替传输方式进行传输时，再将交替传输的任意TB中多个的HARQ反馈生成HARQ反馈信息再进行传输。其中，判断交替传输TB方式被激活的方式可以包括：传输配置信息中的交替传输配置信息被应用，或交替传输的标志位或激活位被置位，或当前TB调度传输中使用所述交替传输TB方式等。
对于按常规方式传输的TB，其对应的HARQ反馈仍然可以现有的一对 一传输，或重复传输等方式进行传输。
如此，仅对交替传输的TB的HARQ反馈，通过生成HARQ反馈信息的方式进行传输，可以减少任意TB中多个的HARQ反馈在时域资源上的重叠；
该方案适用的场景是：基站配置了MTC用户端允许使用交替传输，但是MTC用户端在后续的每次传输中并不一定会一直使用。只有当基站激活了交替传输功能时，MTC用户端才使用生成HARQ反馈信息的方式。
在一些实施例中，所述预设条件，包括：接收的TB的传输配置信息指示允许交替传输TB，并且传输所述接收的任意TB中多个的HARQ反馈的时域资源存在重叠。
在一些实施例中，可以根据所述传输配置信息和物理上行链路控制信道PUCCH重复传输次数，确定用于传输所述接收的任意TB中多个的HARQ反馈的时域资源。
具体的，可以根据TB交替传输中TB的重复次数、总重复次数、PUCCH重复传输次、传输各TB和HARQ反馈使用的时域资源等设置；基站和MTC用户端可以根据TB的传输配置信息的交替传输方式和PUCCH重复传输次数等推算用于传输HARQ反馈的时域资源存在重叠的可能性；交替传输方式可以是每个TB在一个交替传输单元内重复传输次数。如图3所示，一个交替传输单元内每个TB的重复传输次数为2，PUCCH的重复传输次数为4。此时如果采用一对一HARQ反馈，用于传输HARQ反馈的PUCCH时域资源重叠的可能性较高。此时，可以将所述任意TB中多个的HARQ反馈，生成HARQ反馈信息。其中，PUCCH重复传输次数可以表示出HARQ反馈在传输中被重复传输的次数。
当MTC用户端估算出用于传输HARQ反馈的PUCCH时域资源重叠时，将所述任意TB中多个的HARQ反馈，生成所述HARQ反馈信息，并 传输HARQ反馈信息。如此，可以避免传输HARQ反馈在时间上的重叠，从而减小HARQ反馈传输失败率。
例如，当所述传输配置信息确定允许交替传输TB，并且用于传输所述接收的任意TB中多个的HARQ反馈的时域资源存在重叠时；基站和MTC用户端采用默认方式传输，即MTC用户端根据所述任意TB中多个的HARQ反馈，生成HARQ反馈信息，再进行传输，基站接收HARQ反馈信息。
如果基站已经配置了默认采用HARQ反馈绑定传输，则按照配置的方式进行传输；
如果基站没有配置默认采用HARQ反馈绑定传输，在MTC用户端一次，MTC用户端可以根据配置给用户的交替传输方式和PUCCH重复传输次数进行推算，如果存在用于传输HARQ反馈的PUCCH时域资源重叠的情况，则采用生成HARQ反馈信息方式向基站传输HARQ反馈信息，如果不存在时域资源重叠的情况，则使用初始的一对一HARQ反馈传输方式向基站传输HARQ反馈。
在一些实施例中，所述预设条件，包括：接收的TB的传输配置信息指示允许交替传输TB，并且从基站接收的HARQ反馈传输配置指令指示对接收的任意TB中多个的HARQ反馈进行编码，生成HARQ反馈信息。
这里，可以采用基站指令的方式来控制MTC用户端是否采用生成HARQ反馈信息的方式进行HARQ反馈的传输。
在一些实施例中，所述对接收的任意TB中多个的HARQ反馈进行编码，包括：对所述任意TB中多个的HARQ反馈进行按位逻辑与操作，得到所述HARQ反馈信息。
例如，如图5所示，可以将TB1至TB4各自分别对应的HARQ反馈进行按位逻辑与处理，从而得到反映TB1至TB4整体解***况的HARQ反馈 信息。如：TB1的HARQ反馈为“0”表示解调失败，TB2、TB3和TB4的HARQ反馈为“1”表示解调成功，则将所有HARQ反馈按位逻辑与操作后得到HARQ反馈信息“0”，基站接收到HARQ反馈信息后可以得知TB1至TB4中至少有一个TB解调失败，可以将TB1至TB4重新进行发送等处理。
在一些实施例中，采用二相相移键控BPSK调制所述HARQ反馈信息；传输采用所述BPSK调制后的所述HARQ反馈信息。
这里，可以用BPSK调至HARQ反馈信息，以符合PUCCH的要求，将HARQ反馈信息承载在PUCCH进行传输。
将多个HARQ反馈编码为一个HARQ反馈信息，通过PUCCH进行传输，避免了HARQ反馈所承载的PUCCH时间重叠问题，减小了HARQ反馈发送端的工作负载。
在一些实施例中，所述对接收的任意TB中多个的HARQ反馈进行编码，包括：将所述任意TB中多个的HARQ反馈，按组进行HARQ反馈的按位逻辑与操作，得到不同组HARQ反馈；例如，可以将任意TB中多个的HARQ反馈，分为两组，如图6所示，可以将TB1至TB4各自分别对应的HARQ反馈分成两组；TB1的HARQ反馈和TB1的HARQ反馈组成一组，并进行按位逻辑与处理得到1比特的结果，TB3的HARQ反馈和TB4的HARQ反馈组成另一组，并进行按位逻辑与处理得到1比特的结果；将两组分别得到了逻辑与结果组合形成2bit的HARQ反馈信息。如：TB1的HARQ反馈为“0”表示解调失败，TB2、TB3和TB4的HARQ反馈为“1”表示解调成功，则将TB1和TB2的HARQ反馈按位逻辑与操作后得到HARQ反馈信息“1”，将TB3和TB4的HARQ反馈按位逻辑与操作后得到HARQ反馈信息“1”，基站接收到HARQ反馈信息后可以得知TB1和TB2中至少有一个TB解调失败，可以将TB1和TB2重新进行发送等处理。 其中，可以预先约定哪几个TB组成一组。
在一些实施例中，采用正交相移键控QPSK调制所述HARQ反馈信息；传输采用QPSK调制后的所述HARQ反馈信息。
这里，对于2比特的HARQ反馈信息，可以用QPSK调至HARQ反馈信息，以符合PUCCH的要求，将HARQ反馈信息承载在PUCCH进行传输。
将多个HARQ反馈编码为一个HARQ反馈信息，通过PUCCH进行传输，避免了多个HARQ反馈所承载的PUCCH时间重叠问题，减小了HARQ反馈发送端的工作负载。
在一些实施例中，利用PUCCH传输HARQ反馈信息，HARQ反馈信息在完成最后一个TB传输的第三时间间隔后的PUCCH资源上传输。
HARQ反馈信息发送时间以最后一个TB的传输结束时间点为参考点，在最后一个TB传输结束后比如4ms后开始传输。可以为HARQ反馈编码预留出时间。
如此可以确保在所有TB传输完成后在进行HARQ反馈信息的传输，减少出现时序混乱。
HARQ反馈信息可以是一个，从而在传输HARQ反馈信息过程中，可以减少任意TB中多个的HARQ反馈在时间上重叠的情况，减小HARQ反馈发送端处理HARQ反馈的复杂度，减缓HARQ反馈发送端的处理负担，提高HARQ反馈发送端稳定性。
如图7所示，本示例性实施例提供一种HARQ反馈的传输方法，可以应用于MTC***的基站中，但也不限于该***的基站，HARQ反馈的传输方法包括：
当满足预设条件时，针对多传输块TB调度传输，使用HARQ反馈的目标接收方式接收HARQ反馈，其中，所述使用HARQ反馈的目标接收方 式接收HARQ反馈，包括：接收终端对接收的任意TB中多个的HARQ反馈进行编码，生成并传输的HARQ反馈信息。
所述多TB调度传输为采用一个下行控制信道PDCCH资源传输多个TB。
在一些实施例中，所述交替传输TB包括：循环传输TB交替传输单元直至满足每个所述TB被配置的总重复传输次数，其中所述TB交替传输单元包含不同TB的N次重复传输，N为大于0并且小于M，M为所述总重复传输次数。
这里，一个TB交替传输单元包括：至少两个TB，这些TB按照一定的顺序进行排序，形成一个TB交替传输单元。
其中，这里的TB是一种内容块；不同的TB包含的数据内容不同。如图2所示，一个TB的总重复传输次数为4，在一个TB交替传输单元中，一个TB被重复传输N次，图2中N为2。4次总重复传输的TB1中的数据内容相同，TB1和TB2中包含的数据内容不同。4次传输的TB1的内容相同。通过交替传输，可以实现同一个TB的接收功率的累加，从而增加快TB的接收端的解码成功率。
在一些实施例中，一个TB具有一个HARQ反馈。
当然在另一些实施例中，多次重复传输的TB可具有多个HARQ反馈。若一个TB具有一个HARQ反馈，如此减少了不必要的HARQ反馈所占用的传输资源，节省了传输开销。
在交替传输中，一个TB会被交替重复传输多次，HARQ反馈发送端接收到多次传输的该TB后，会将多次接收到的该TB一起进行解调；解调结果通过HARQ反馈传输回TB发送端；HARQ反馈包括：ACK和NACK等。
具体地如，如果解调结果正确则反馈ACK，和/或，如果解调结果不正 确则反馈NACK。
如图2所示，TB1在交替重复传输中共被传输4次，HARQ反馈发送端解析4次重复传输的TB1后会向基站发送一个HARQ反馈以反馈TB1是否被正确解调。图2所示的TB1至TB4的交替传输中，HARQ反馈发送端会向基站传输TB1至TB4各自分别对应的共4个HARQ反馈。
这里，可以将任意TB中多个的HARQ反馈进行预定编码，得到由多个HARQ反馈编码而成的HARQ反馈信息；HARQ反馈信息内容由可以根据预定编码确定，可以反应出多个TB的解调结果信息，如可以整体反馈反应出是否多个TB均被正确解调。
HARQ反馈信息可以是一个，从而在传输HARQ反馈信息过程中，可以减少任意TB中多个的HARQ反馈在时间上重叠的情况，减小HARQ反馈发送端处理HARQ反馈的复杂度，减缓HARQ反馈发送端的工作负担，提高HARQ反馈发送端稳定性。
基站可以预先设置HARQ反馈的接收方式规则；HARQ反馈的传输方式规则用于定义预设条件和HARQ反馈的目标接收方式。当满足预设条件时，则采用HARQ反馈的目标接收方式接收HARQ反馈信息。
MTC用户端的HARQ反馈的传输方式规则可以和基站的HARQ反馈的接收方式规则向对应，确保MTC用户端发送HARQ反馈信息时，基站采用对应的接收HARQ反馈信息的方式接收。
如此，当预设条件时，基站不需要额外的信令对MTC用户端的HARQ反馈传输方式进行配置，而是根据预先设置HARQ反馈的接收方式规则进行处理，简化配置流程，节约信令开销。
在一些实施例中，所述预设条件，包括：发送的TB的传输配置信息指示允许交替传输TB。
当MTC用户端被配置允许使用交替传输时，则MTC用户端默认采用 将任意TB中多个的HARQ反馈编码生成HARQ反馈信息再进行传输。此时基站侧默认采用接收HARQ反馈信息的方式进行接收。
这里，确定所述传输配置信息确定允许交替传输TB的方式可以是：如果TB的传输配置信息中包含交替传输配置信息或其他预定信息，则确定允许交替传输TB。HARQ反馈对应的TB，可以是交替传输的TB，也可以是采用常用方式进行传输的TB。
如此，当所述传输配置信息确定允许交替传输TB时，说明有出现交替传输TB的可能，基站不需要额外的信令对MTC用户端的HARQ反馈传输方式进行配置，而是根据预先设置HARQ反馈的传输方式规则进行处理，简化配置流程，节约信令开销。
在一些实施例中，所述预设条件，包括：发送的TB的传输配置信息指示允许交替传输TB，并且激活了交替传输TB方式。
这里，预先设置HARQ反馈的传输方式规则可以将预设条件设为只有当交替传输TB方式被激活时，即TB采用交替传输方式进行传输时，接收HARQ反馈信息。其中，判断交替传输TB方式被激活的方式可以包括：传输配置信息中的交替传输配置信息被应用，或交替传输的标志位或激活位被置位，或当前TB调度传输中使用所述交替传输TB方式等。
对于按常规方式传输的TB，其对应的HARQ反馈仍然可以现有的一对一传输，或重复传输等方式进行传输。
如此，仅对交替传输的TB的HARQ反馈，通过生成HARQ反馈信息的方式进行传输，可以减少任意TB中多个的HARQ反馈在时域资源上的重叠。
该方案适用的场景是：基站配置了MTC用户端允许使用交替传输，但是MTC用户端在后续的每次传输中并不一定会一直使用。只有当基站激活了交替传输功能时，MTC用户端才使用生成HARQ反馈信息的方式。
在一些实施例中，所述预设条件，包括：发送的TB的传输配置信息指示允许交替传输TB，并且传输所述接收的任意TB中多个的HARQ反馈的时域资源存在重叠。
在一些实施例中，根据所述传输配置信息和物理上行链路控制信道PUCCH重复传输次数，确定用于传输所述接收的任意TB中多个的HARQ反馈的时域资源。
具体的，预设估算规则可以根据TB交替传输中TB的重复次数、总重复次数、PUCCH重复传输次、传输各TB和HARQ反馈使用的时域资源等设置；基站和MTC用户端可以根据TB的传输配置信息的交替传输方式和PUCCH重复传输次数等推算用于传输HARQ反馈的时域资源存在重叠的可能性；交替传输方式可以是每个TB在一个交替传输单元内重复传输次数。如图3所示，一个交替传输单元内每个TB的重复传输次数为2，PUCCH的重复传输次数为4。此时如果采用一对一HARQ反馈，用于传输HARQ反馈的PUCCH时域资源重叠的可能性较高。此时，可以将所述任意TB中多个的HARQ反馈，生成HARQ反馈信息。其中，PUCCH重复传输次数可以表示出HARQ反馈在传输中被重复传输的次数。
基站和MTC用户端基于同样预设估算规则，可以估算出用于传输HARQ反馈的PUCCH时域资源重叠；此时，MTC用户端将所述任意TB中多个的HARQ反馈，生成所述HARQ反馈信息，并传输HARQ反馈信息。基站接收HARQ反馈信息；如此，可以避免传输HARQ反馈在时间上的重叠，从而减小HARQ反馈传输失败率。
例如，当所述传输配置信息确定允许交替传输TB，并且用于传输所述接收的任意TB中多个的HARQ反馈的时域资源存在重叠时；基站和MTC用户端采用默认方式传输，即MTC用户端根据所述任意TB中多个的HARQ反馈，生成HARQ反馈信息，再进行传输，基站接收HARQ反馈信 息。
如果基站通过基站指令已经配置了HARQ反馈绑定传输，则基站和MTC用户端按照配置的方式进行传输。
如果没有配置HARQ反馈绑定传输，在基站一侧，基站根据配置给用户的交替传输方式和PUCCH重复传输次数进行推算，如果用于传输HARQ反馈的PUCCH时域资源存在重叠的情况，则接收HARQ反馈信息；如果不存在时域资源重叠的情况，则基站接收使用一对一HARQ反馈传输方式传输的HARQ反馈。
在一些实施例中，所述预设条件，包括：发送的HARQ反馈传输配置指令指示所述终端对接收的任意TB中多个的HARQ反馈进行编码，生成HARQ反馈信息。
这里，可以采用基站指令的方式来控制MTC用户端是否采用生成HARQ反馈信息的方式进行HARQ反馈的传输。
在一个实施例中，基站接收HARQ反馈信息，如图8所示，具体包括如下步骤：
步骤801：接收所述任意TB中多个的HARQ反馈进行编码的HARQ反馈信息；
步骤802：根据与所述编码对应的解调方式对所述HARQ反馈信息进行解码，得到解码序列；
步骤803：根据所述解码序列，确定所述多个TB的解调状况。
其中，交替传输多个不同TB包括：循环传输TB交替传输单元直至满足每个TB被配置的总重复传输次数，其中TB交替传输单元包含不同TB的N次重复传输，N为大于0并且小于被配置的总重复传输次数。
一个TB交替传输单元包括：至少两个TB，这些TB按照一定的顺序进行排序，形成一个TB交替传输单元。
这里，可以由基站等TB发送端发送TB交替传输单元；HARQ反馈发送端如MTC用户端，接收多个不同TB后，对TB进行解码，将各TB的HARQ反馈通过预定编码得到一个HARQ反馈信息，并经过与预定编码对应的调制方式调制后发送该HARQ反馈信息，可以减少HARQ反馈在时间上重叠的情况，减HARQ反馈发送端处理HARQ反馈的复杂度，降低对HARQ反馈发送端的性能需求，进而提升HARQ反馈信息发送成功率，提高HARQ反馈发送端稳定性。这里，一个HARD反馈可以用一个时域资源进行传输。其中，编码得到的HARQ反馈信息可以反应多个不同TB的解调状况。
HARQ反馈接收端如基站等，将接收到的HARQ反馈信息采用预定编码对应的解调方式进行解码，得到解码序列，解码出解码序列可以反应多个不同TB的解调状况。
在一些实施例中，若解码序列是预设序列，确定多个不同TB均成功接收。
预设序列可以根据预定编码方式确定。如预定编码产生的结果中“1”表示多个不同TB均成功接收，则可以将预设序列设置为“1”。
具体地如，如图5所示，HARQ反馈发送端如MTC用户端可以将TB1至TB4各自分别对应的HARQ反馈进行预定编码，如逻辑与处理，从而得到反映TB1至TB4整体解***况的HARQ反馈信息。HARQ反馈可以用“0”表示解调失败，“1”表示解调成功。如：TB1、TB2、TB3和TB4的HARQ反馈为“1”表示解调成功，则将所有HARQ反馈按位逻辑与操作后得到HARQ反馈信息“1”，表示TB1、TB2、TB3和TB4解调均成功，这里，可以将预设序列设置为“1”。
当预设序列为“1”时，HARQ反馈接收端接收到HARQ反馈信息进行解调后得到的解码序列为“1”，与预设序列一致，则认为多个TB均解调 成功。
在一些实施例中，若解码序列不是预设序列，确定至少一个TB未解调成功。
以预设序列为“1”为例，当TB1、TB2、TB3和TB4的HARQ反馈中有一个为“0”时，则将所有HARQ反馈按位逻辑与操作后得到HARQ反馈信息“0”，表示TB1、TB2、TB3和TB4中至少有一个解调失败。
HARQ反馈接收端如基站接收到HARQ反馈信息进行解调后得到的解码序列为“0”，与预设序列不一致，则认为至少一个TB未解调成功。
在一些实施例中，若至少一个TB未解调成功，重新传输整个TB交替传输单元。
这里，确定TB交替传输单元中至少一个TB未解调成功后，可以由基站重新传输TB交替传输单元。
在一些实施例中，利用BPSK或QPSK的解调方式进行HARQ反馈信息的解码，获得解码序列。
预定编码可以是对多个不同TB的HARQ反馈进行按位逻辑与操作，得到1比特的HARQ反馈信息；也可以将多个不同TB的HARQ反馈，按组进行HARQ反馈的按位逻辑与操作的组HARQ反馈；将不同组HARQ反馈进行组合得到2比特的HARQ反馈信息。
对于预定编码后产生1比特的HARQ反馈信息可以采用BPSK调制发送，因此，在HARQ反馈接收端可以采用BPSK的解调方式进行HARQ反馈信息的解码。
对于预定编码后产生2比特的HARQ反馈信息可以采用QPSK调制发送，因此，在HARQ反馈接收端可以采用QPSK的解调方式进行HARQ反馈信息的解码。
而本实施例中针对这种交替传输的多个不同TB的HARQ反馈，HARQ 反馈接收端接收多个不同TB的HARQ反馈进行预订编码的HARQ反馈信息，进而判断多个不同TB的解调状况。如此可以避免不同TB的HARQ反馈占用相同的时域资源，导致需要在时域上传输正交引入的复杂度，从而降低了HARQ反馈的发送端发送HARQ反馈时的处理复杂度，尤其对于处理能力较弱的MTC等终端而言，可以减少因为HARQ反馈的发送复杂度高导致的发送失败的现象，提升了HARQ反馈的发送成功率。
以下结合上述任意实施例提供几个具体示例：
方案核心：提前预定义一套HARQ反馈传输方式的规则，使得基站和MTC用户端能自动切换HARQ反馈的方式，避免任意TB中多个的HARQ反馈在时间上重叠，同时减少信令开销。
方案一：一旦MTC用户端被配置允许使用交替传输那么基站和MTC用户端默认采用HARQ反馈绑定传输；此时基站不需要额外的信令对用户的HARQ反馈方式进行配置。
这里，绑定传输，是指根据所述任意TB中多个的HARQ反馈，生成HARQ反馈信息并进行传输。
方案二：当MTC用户端被配置使用交替传输，并且存在用于传输HARQ反馈的PUCCH时域资源有重叠的情况时，基站和MTC用户端默认采用HARQ反馈绑定传输方式。
如果基站已经配置了HARQ反馈绑定传输，此时则按照配置的方式进行传输。
如果基站一开始没有配置HARQ反馈绑定传输，在基站端，基站根据配置给MTC用户端的传输块TB的传输配置信息中交替传输方式和PUCCH重复传输次数进行推算，如果存在用于传输HARQ反馈的PUCCH时域资源有重叠的情况时，则使用HARQ反馈绑定传输，如果不存在，则使用一对一HARQ反馈方式。
其中，基站和MTC用户端可以根据TB的传输配置信息的交替传输方式和PUCCH重复传输次数等推算用于传输HARQ反馈的时域资源存在重叠的可能性；交替传输方式可以是每个TB在一个交替传输单元内重复传输次数。如图3所示，一个交替传输单元内每个TB的重复传输次数为2，PUCCH的重复传输次数为4。此时如果采用一对一HARQ反馈，用于传输HARQ反馈的PUCCH时域资源重叠的可能性较高。此时，可以将所述任意TB中多个的HARQ反馈，生成HARQ反馈信息。
方案三：当MTC用户端被配置可以使用交替传输方式，并且交替传输方式被激活时，无论基站是否进行了配置，都使用HARQ反馈绑定传输
这种方案主要针对的场景是：基站配置了MTC用户端允许使用交替传输，但是MTC用户端在后续的每次传输中并不一定会一直使用。只有当基站激活了交替传输功能时MTC用户端才使用HARQ反馈绑定传输。
方案四：当MTC用户端被配置可以使用交替传输方式，并且用于传输HARQ反馈的PUCCH时域资源产生重叠的情况时，基站和用户默认采用HARQ反馈绑定传输方式。
