本申请主张在2018年11月1日在中国提交的中国专利申请No.201811296928.3的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种混合自动重传的传输方法、装置、网络设备及终端。
背景技术
随着移动通信业务需求的发展变化，3GPP等多个组织对未来移动通信系统都开始研究新的无线通信系统(5 Generation New RAT，5G NR)。在5G NR系统中，一个重要的需求是低时延、高可靠的通信，出现了超高可靠低时延(The Ultra Reliable Low Latency Communications，URLLC)等传输方案。单纯的低时延需求或者单纯的高可靠需求，均比较容易实现，但是，低时延需求和高可靠需求同时满足是难实现的，通常以高复杂度为代价来实现。
对于URLLC业务，在NR标准中，将会支持上行免调度方案，以减少空口传输时延，同时会支持重复传输方案，以增加可靠性。
在NR标准中，混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)反馈方案是：在UE侧设置一个定时器(timer)，如果物理上行共享信道(Physical Uplink Shared Channel，PUSCH)接收错误，gNB在timer到时之前发送一个PUSCH重新传输的下行控制信息(DCI)调度信令，指示UE重新传输这个PUSCH；如果PUSCH接收正确，gNB可以不做任何反馈，UE会在timer到时之后自动认为PUSCH已被正确接收了。
如图1所示，UE在完成一个传输块TB(包括K次重复传输)的传输后，立即启动内部的定时器。在定时器到时之前，如果UE收到gNB的下行控制信息(Downlink Control Information，DCI)，调度对该TB进行重新传输，那么UE认为收到了NACK，即TB传输没有被正确接收；在定时器到时之前， 如果UE没有收到gNB的针对该TB的重新传输的调度DCI，那么UE认为收到了ACK，即TB传输被正确接收。
如果UE发送了PUSCH，但是gNB什么也没有检测到，即gNB认为UE没有发送PUSCH，这种情况称为漏检(miss-detection)，这时gNB不会有任何HARQ反馈，在定时器到时之后，UE认为TB传输被正确接收。这就会严重影响URLLC业务的可靠性和时延特性。
相关技术的缺点是HARQ反馈会大量消耗掉下行控制信令资源，使得下行控制信令资源出现不足的问题。

如果系统支持早期终止(early termination)功能，那么在接收完一次重复传输之后(如图3中一个TB中第0次传输)，基站可以开始发送下行控制信令，包括PDCCH和显式HARQ；
如果系统不支持早期终止(early termination)功能，那么在接收完所有重复传输(如图3中的一个TB的结束，即第3次传输)之后，基站可以开始发送下行控制信令。基站在接收完所有重复传输时启动一个定时器，等定时器到时后，基站不能发送针对所述PUSCH的下行控制信令。

基站在接收完所有重复传输(如图4中的一个TB的结束，即第3次传输)时启动一个定时器，等定时器到时后，基站不能发送针对所述PUSCH的下行控制信令。
(i)在接收到部分或全部重复传输后，基站向UE发送PDCCH用同样的HARQ ID调度新的PUSCH传输。
(ii)在接收到部分或全部重复传输后，基站向UE发送PDCCH用同样的HARQ ID调度PUSCH的重新传输。

步骤2：UE在配置的资源上进行PUSCH传输，如图所示，在时隙(slot)/微时隙(mini-slot)上进行K＝4次重复传输。
步骤3：如果系统支持early termination功能，那么在一次重复传输之后， UE需要开始监测是否有关于PUSCH的下行控制信令；如果系统不支持early termination功能，那么在K次重复传输(即一个TB，TB为传输块)之后，UE需要开始监测是否有关于PUSCH的下行控制信令。
步骤4：UE在K次重复传输完成后，启动一个定时器。在定时器到时之后，UE停止监测是否有关于PUSCH的下行控制信令。
步骤5：如果UE监测到PDCCH调度了上述PUSCH对应的HARQ ID的新TB，那么UE结束掉自己当前的重复传输后，按照PDCCH的信息传输新的TB；
如果UE监测到PDCCH调度了上述PUSCH对应的HARQ ID的重新传输，那么UE结束掉自己当前的重复传输后，按照PDCCH的信息重新传输该TB；
如果UE监测到下行控制信令中有NACK信息，那么UE结束掉自己当前的重复传输后，使用新的HARQ ID重新传输该TB；
如果UE监测到下行控制信令中有DTX信息，那么UE结束掉自己当前的重复传输后，使用新的HARQ ID重新传输该TB。
当UE监测到下行控制信令后，UE即停止定时器。
步骤6：在定时器到时之后，UE认为PUSCH已经被正确接收。
如图4所示，上述实施例的另一种实现过程包括：
步骤1：在RRC配置信令Configured Grant Config中，增加一个新的字段，比如HARQ-explicit，用于指示基站是否会向UE发送显式HARQ信息；或者在激活信令DCI中，增加一个比特或修改已有比特的含义，比如重新定义激活信令DCI中HARQ process number这个字段的最高比特位，用于指示基站是否会向UE发送显式HARQ信息；
UE接收基站发送的上行免调度传输的配置信息；对应Type 2上行免调度传输，UE还需要接收激活DCI，以启动上行免调度传输。
步骤2：UE在配置的资源上进行PUSCH K次重复传输。
步骤3：如果系统可以支持early termination功能，那么在一次重复传输之后，UE需要开始监测是否有关于PUSCH的下行控制信令；如果系统明确不支持early termination功能，那么在K次重复传输之后，UE需要开始监测 是否有关于PUSCH的下行控制信令。
步骤4：UE在K次重复传输完成后，启动一个定时器。在定时器到时之后，UE停止监测是否有关于PUSCH的下行控制信令。
步骤5：如果UE监测到PDCCH调度同一个HARQ ID的新TB，那么UE结束掉自己当前的重复传输后，按照PDCCH的信息传输新的TB；
如果UE监测到PDCCH调度同一个HARQ ID的重新传输，那么UE结束掉自己当前的重复传输后，按照PDCCH的信息重新传输该TB；
如果UE监测到下行控制信令中有ACK信息，那么UE结束掉自己当前的重复传输后，可以继续传输新的TB。当UE监测到下行控制信令后，UE即停止定时器。
步骤6：在定时器到时之后，UE认为PUSCH没有被正确接收，将使用同样的HARQ ID进行重新传输，或者使用新的HARQ ID进行重新传输。
本公开的上述实施例，UE收到基站发送的PUSCH没有被正确接收的下行控制信令后，使用新的HARQ ID进行PUSCH的重新传输。在解决miss-detection的前提下，可以实现解决HARQ反馈消耗太多下行控制信令资源的问题。
