本申请要求于2020年08月05日提交的申请号为2020107777577，发明名称为“信息传输方法、装置、终端、基站及存储介质”的中国专利申请的优先权，其通过引用方式全部并入本文。
技术领域
本申请涉及通信技术领域，尤其涉及一种信息传输方法、装置、终端、基站及存储介质。
背景技术
R17标准新引入了功能降低的NR设备(Reduced capability NR devices，简称“Redcap UE”)，Redcap UE是以5G通用终端UE为基础，在能力上或者复杂度上的进行裁剪后的UE。
5G基站(gNB)是通过物理下行控制信道(Physical Downlink Control Channel,PDCCH)提供UE物理下行共享信道(Physical Downlink Shared Channel,PDSCH)的调度信息。5G基站会通过PDCCH调度一个PDSCH发给UE，UE根据PDSCH是否正确解码反馈HARQ-ACK信息。
由于Redcap UE天线个数的减少导致PDCCH的解调性能会下降，需要增强PDCCH的解调性能。常规的手段是用更大的聚合等级(Aggregation Level,AL)。
但RedCap受限于带宽大小，AL也是受限的，无法提高PDCCH的解调性能，因此，针对Redcap UE，如何提高PDCCH的解调性能，是亟需解决的技术问题。

具体实施方式
本申请主要解决在第五代移动通信新空口(the 5th generation mobile communication New Radio,5G NR)系统中，由于半静态配置的物理下行控制信道重复传输(PDCCH repetition)次数无法自适应的根据信道变化来调整PDCCH repetition次数，这会影响PDCCH解调性能下降或者网络开销增大的技术问题。
Redcap终端主要是针对目前的5G通用终端进行能力上或者复杂度上的进行裁剪例如：支持最大带宽的裁剪(从100MHz带宽减少到20MHz带宽)，天线数的减少(从4根接收天线减少到2根或者1根接收天线)。
目前5G基站(gNB)是通过物理下行控制信道(PDCCH)提供UE物理下行共享信道(PDSCH)的调度信息。
图1是物理下行控制信道调度示意图，如图1所示。5G基站会通过PDCCH调度一个PDSCH发给终端，终端根据PDSCH是否正确解码反馈混合自动重传请求确认(Hybrid Automatic Repeat reQuest Acknowledge,HARQ-ACK)信息。
图2是终端带有不同接收天线的下行覆盖示意图，如图2所示，具有不同数目接收天线的终端的下行覆盖半径是不同的(UE 4RX>UE 2RX>UE 1RX),这是由于天线数减少导致UE的传输性能不能达到原本4天线的覆盖范围，如果要将1根天线和2根天线的UE恢复到4根天线的下行覆盖范围，就需要对PDCCH进行增强。
由于Redcap UE天线个数的减少导致PDCCH的解调性能会下降，因此需要增强PDCCH的解调性能。常规的手段是用更大的聚合等级 (Aggregation Level,AL)，但RedCap受限于带宽大小，AL也是受限的，因此可能考虑PDCCH repetition，但是常规的repetition方法是一种半静态调度的，如果信道发生快速变化，PDCCH repetition次数不能够及时的更新，这会影响PDCCH解调性能和网络开销。
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
图3是本申请实施例提供的一种信息传输方法示意图之一，如图3所示，本申请实施例提供一种信息传输方法，其执行主体可以为终端，该方法包括：
步骤301、根据默认的物理下行控制信道PDCCH重复传输次数接收PDCCH重复传输指示信息；所述PDCCH重复传输指示信息是由基站根据当前的信道质量确定的。
具体来说，图4是本申请实施例提供的信息传输方法的交互流程示意图，如图4所示，基站根据当前的信道质量确定PDCCH重复传输指示信息。
PDCCH重复传输指示信息中至少包括PDCCH重复传输次数RepK。还可以包括新数据指示符NDI。
基站确定PDCCH重复传输指示信息之后，根据默认的PDCCH重复传输次数将PDCCH重复传输指示信息发送至终端。该默认的PDCCH重复传输次数可以是由基站预先通过广播信令发送给终端的。
终端根据默认的PDCCH重复传输次数接收PDCCH重复传输指示信息。
步骤302、根据所述PDCCH重复传输指示信息接收PDCCH信 息。
具体来说，终端接收到PDCCH重复传输指示信息之后，根据PDCCH重复传输指示信息接收PDCCH信息。
终端接收到PDCCH重复传输指示信息之后，还可以向基站发送对应的确认信息。基站在接收到对应的确认信息之后，延迟预设时长T之后，向终端发送PDCCH信息。
本申请实施例提供的信息传输方法，由基站根据当前的信道质量向终端发送PDCCH重复传输指示信息，终端根据PDCCH重复传输指示信息接收PDCCH信息，能够自适应地调整PDCCH重复传输次数，提高了PDCCH的解调性能。
基于上述任一实施例，所述PDCCH重复传输指示信息通过PDCCH、媒体访问控制控制元素MAC CE或者无线资源控制RRC信令承载。
具体来说，在本申请实施例中，终端接收到的PDCCH重复传输指示信息可以通过PDCCH承载，即，在下行控制信息(Downlink Control Information,DCI)中增加一个PDCCH RepK指示域。
也可以通过媒体访问控制控制元素MAC CE承载，即，在MAC CE中增加PDCCH重复传输的信息单元并且该MAC CE通过PDSCH承载。
还可以无线资源控制(Radio Resource Control,RRC)信令承载。
本申请实施例提供的信息传输方法，可以通过PDCCH、媒体访问控制控制元素MAC CE或者无线资源控制RRC信令承载PDCCH重复传输指示信息，提高了系统的灵活性。
基于上述任一实施例，所述PDCCH重复传输指示信息通过下行控制信息DCI携带。
具体来说，在本申请实施例中，终端接收到的PDCCH重复传输指示信息可以通过PDCCH承载，即，在下行控制信息(Downlink  Control Information,DCI)中增加一个PDCCH RepK指示域，由DCI携带PDCCH重复传输指示信息。
本申请实施例提供的信息传输方法，通过DCI携带PDCCH重复传输指示信息，降低了信令开销。
基于上述任一实施例，所述根据所述PDCCH重复传输指示信息接收PDCCH信息，具体包括：
若成功解调出PDCCH调度的物理下行共享信道PDSCH，则向基站反馈确认ACK信息；
延迟预设时长T之后，根据所述PDCCH重复传输指示信息指示的PDCCH重复传输次数接收PDCCH信息。
具体来说，在本申请实施例中，终端成功解调出PDCCH调度的物理下行共享信道PDSCH之后，向基站反馈确认ACK信息。
PDCCH重复传输指示信息所指示的PDCCH重复传输次数在PDSCH的HARQ-ACK反馈之后的预设时长T之后开始生效。
基站接收终端反馈的确认ACK信息。
基站接收到终端反馈的确认ACK信息之后，再延迟预设时长T，然后，根据PDCCH重复传输指示信息指示的PDCCH重复传输次数向终端发送PDCCH信息。
终端向基站反馈确认ACK信息之后，再延迟预设时长T，然后根据PDCCH重复传输指示信息指示的PDCCH重复传输次数接收PDCCH信息。
本申请实施例提供的信息传输方法，基站接收到ACK信息之后，延迟预设时长发送PDCCH信息，终端发送ACK信息之后，延迟预设时长接收PDCCH信息，明确了更新的PDCCH重复传输次数的实施时间点，保证了终端和基站对于实施点理解一致，避免PDCCH信息接收混乱。
基于上述任一实施例，当承载所述ACK信息的物理上行控制信 道PUCCH未配置重复传输机制时，所述T的起始时间为所述ACK信息所在时隙slot的最后一个正交频分复用OFDM符号，或者为所述ACK信息所在slot的第一个OFDM符号，或者为所述ACK信息所占用的OFDM符号中的最后一个OFDM符号，或者为所述ACK信息所占用的OFDM符号中的第一个OFDM符号；
当承载所述ACK信息的PUCCH配置重复传输机制时，所述T的起始时间为整个PUCCH重复束的最后一个OFDM符号，或者为整个PUCCH重复束的第一个OFDM符号。
具体来说，在本申请实施例中，确定PDCCH重复传输次数更新的时间点方法如下：
PDCCH重复传输次数更新的时间点是终端确定所述指示信息所指示的PDCCH重复传输次数在所述PDSCH的HARQ-ACK反馈之后的预设时长之后开始生效。
进一步说明：PDSCH的HARQ-ACK反馈之后的预设时长之后开始生效是指承载ACK的PUCCH所在的OFDM符号之后T时间之后的第一个监听时间(Monitoring Occasion,MO)生效。
方法1：预设时长T表现为以符号为单位的数值，起始时间参考点可以是承载HARQ-ACK的PUCCH的第一个符号或最后一个符号，当然也可以定义为承载HARQ-ACK的PUCCH所在时隙或子时隙的第一个符号或最后一个符号，即以符号为单位的定义更为细致。
如果HARQ-ACK使用重复传输，则起始时间参考点可以是承载HARQ-ACK的PUCCH重复传输中的最后一次传输的第一个符号或最后一个符号或第一次传输的第一个符号或最后一个符号，当然也可以定义为承载HARQ-ACK的PUCCH重复传输中的最后一次传输所在时隙或子时隙的第一个符号或最后一个符号或第一次传输所在时隙或子时隙的第一个符号或最后一个符号。
方法2：预设时长T表示为以时隙或子时隙为单位的数值，起始 时间参考点可以是承载HARQ-ACK的PUCCH传输所在的时隙或子时隙。
如果HARQ-ACK使用重复传输，则起始时间参考点可以是承载HARQ-ACK的PUCCH重复传输中的最后一次传输或第一次传输所在的时隙或子时隙。
其中，上述HARQ-ACK具体可以为ACK，即当PDSCH正确解析时，基于ACK反馈的时刻以及T时间确定重复传输次数的生效时间；对于反馈是NACK的情况，因为理解为重复传输次数可能并未成功接收到，因此不需要判断是否生效。
本申请实施例提供的信息传输方法，基站接收到ACK信息之后，延迟预设时长发送PDCCH信息，终端发送ACK信息之后，延迟预设时长接收PDCCH信息，明确了更新的PDCCH重复传输次数的实施时间点，保证了终端和基站对于实施点理解一致，避免PDCCH信息接收混乱。
基于上述任一实施例，所述延迟预设时长T之后，根据所述PDCCH重复传输指示信息指示的PDCCH重复传输次数接收PDCCH信息，具体包括：
从延迟所述T之后的第一个PDCCH监听时间MO开始，将m个PDCCH MO划分为一组；m为所述PDCCH重复传输指示信息指示的PDCCH重复传输次数；
按照m个PDCCH MO为一组接收PDCCH信息。
具体来说，在本申请实施例中，PDCCH检测窗的确定方法：
如果PDCCH重复传输次数为m，终端从发送确认信息ACK所在OFDM符号加上一个确定时间之后的第一个PDCCH MO开始按照m个PDCCH MO为一组进行PDCCH MO划分，并按照m个PDCCH MO为一组进行PDCCH接收。
对m个PDCCH MO计数处理有两种方法：
(1)对m个PDCCH MO所在的slot进行连续计数，如果一个MO是否包含flexible符号或UL符号一并计入到m个PDCCH MO之中。
(2)在统计m个PDCCH MO时，一个MO是否包含flexible符号或UL符号不计入PDCCH MO统计。
本申请实施例提供的信息传输方法，根据自适应地调整的PDCCH重复传输次数，将m个PDCCH MO划分为一组，按照m个PDCCH MO为一组接收PDCCH信息，进一步提高了PDCCH的解调性能。
基于上述任一实施例，所述按照m个PDCCH MO为一组接收PDCCH信息，具体包括：
逐个利用一组PDCCH MO中的PDCCH MO接收PDCCH信息；
若利用当前的第k个PDCCH MO成功解调出PDCCH信息，则不再利用本组中剩余的PDCCH MO接收PDCCH信息，其中，k<m。
具体来说，在本申请实施例中，按照m个PDCCH MO为一组接收PDCCH信息的具体步骤如下：
终端逐个利用一组PDCCH MO中的PDCCH MO接收PDCCH信息，一边接收，一边解调。
如果利用当前的第k个PDCCH MO成功解调出PDCCH信息，则不再利用本组中剩余的PDCCH MO接收PDCCH信息，其中，k<m。
例如，PDCCH重复传输次数为10，终端在利用第6个PDCCH MO已经成功解调出PDCCH信息，则不再利用第7-10个PDCCH MO接收PDCCH信息。
本申请实施例提供的信息传输方法，终端根据自适应地调整的PDCCH重复传输次数接收PDCCH信息的过程中，一边接收，一边解调，进一步降低了网络开销。
基于上述任一实施例，所述PDCCH重复传输指示信息包括 PDCCH重复传输次数和新数据指示符NDI；
所述根据所述PDCCH重复传输指示信息接收PDCCH信息，具体包括：
若成功解调出PDCCH调度的PDSCH，则向基站反馈确认ACK信息；
接收基站发送的未翻转的NDI；所述未翻转的NDI是所述基站接收到非确认NACK信息之后发送的；
根据旧的PDCCH重复传输次数接收PDCCH信息；所述旧的PDCCH重复传输次数为基站在上一PDCCH重复传输次数调整周期中为终端配置的PDCCH重复传输次数。
具体来说，为了防止基站和终端由于HARQ-ACK反馈的误检和漏检导致对于PDCCH重复传输次数理解不一致的情况，本申请实施例采用如下机制：PDCCH重复传输指示信息包括PDCCH重复传输次数和新数据指示符NDI，即，引入一个新的指示信息域PDCCH Repk NDI，这个指示域的作用就是在Repk更新的时候进行翻转(从0变成1或者从1变成0)。如果基站在PDCCH重复传输次数更新的时间点实施新的PDCCH重复传输次数地同时将PDCCH RepK NDI进行翻转。但是，当终端发送的HARQ-ACK的信息为ACK时，基站接收到的是NACK，这时候，基站会在PDCCH重复传输次数更新的时间点按照旧的PDCCH重复传输次数传输PDCCH同时PDCCH RepK NDI保持不变，当终端接收到PDCCH的时候，在检测PDCCH RepK NDI没有翻转就知道当前的PDCCH重复传输次数没有改变会按照旧的PDCCH重复传输次数接收后续的PDCCH。
终端根据PDCCH重复传输指示信息接收PDCCH信息的具体步骤如下：
如果成功解调出PDCCH调度的PDSCH，则终端向基站反馈确认ACK信息。
但是，由于各种因素导致基站接收到的是非确认NACK信息，然后基站将未翻转的NDI发送至终端。
终端接收基站发送的未翻转的NDI。
然后，根据旧的PDCCH重复传输次数接收PDCCH信息；该旧的PDCCH重复传输次数为基站在上一PDCCH重复传输次数调整周期中为终端配置的PDCCH重复传输次数。
本申请实施例提供的信息传输方法，PDCCH重复传输指示信息包括PDCCH重复传输次数和NDI，避免了基站和终端由于HARQ-ACK反馈的误检和漏检导致对于PDCCH重复传输次数理解不一致的情况。
基于上述任一实施例，所述PDCCH重复传输指示信息包括PDCCH重复传输次数和新数据指示符NDI；
所述根据所述PDCCH重复传输指示信息接收PDCCH信息，具体包括：
若成功解调出PDCCH调度的PDSCH，则向基站反馈确认ACK信息；
接收基站发送的翻转的NDI；所述翻转的NDI是所述基站接收到所述确认ACK信息之后发送的；
根据所述PDCCH重复传输指示信息中包含的PDCCH重复传输次数接收PDCCH信息。
具体来说，为了防止基站和终端由于HARQ-ACK反馈的误检和漏检导致对于PDCCH重复传输次数理解不一致的情况，本申请实施例采用如下机制：PDCCH重复传输指示信息包括PDCCH重复传输次数和新数据指示符NDI，即，引入一个新的指示信息域PDCCH Repk NDI，这个指示域的作用就是在Repk更新的时候进行翻转(从0变成1或者从1变成0)。
终端根据PDCCH重复传输指示信息接收PDCCH信息的具体步 骤如下：
如果成功解调出PDCCH调度的PDSCH，则终端向基站反馈确认ACK信息。
基站接收到ACK信息之后，将翻转的NDI发送至终端。
终端接收基站发送的翻转的NDI。
然后，根据PDCCH重复传输指示信息中包含的PDCCH重复传输次数接收PDCCH信息。
本申请实施例提供的信息传输方法，PDCCH重复传输指示信息包括PDCCH重复传输次数和NDI，避免了基站和终端由于HARQ-ACK反馈的误检和漏检导致对于PDCCH重复传输次数理解不一致的情况。
基于上述任一实施例，所述根据所述PDCCH重复传输指示信息接收PDCCH信息，具体包括：
根据所述PDCCH重复传输指示信息接收PDCCH信息；
统计未成功接收PDCCH信息的次数；
若未成功接收PDCCH信息的次数超过预设阈值，则向基站发起随机接入，其中，所述预设阈值是通过高层信令进行配置的或者是一个预设常数。
具体来说，当终端发送的HARQ-ACK的信息为NACK时，基站接收到的是ACK，然后，基站在PDCCH重复传输次数更新的时间点实施新的PDCCH重复传输次数同时将PDCCH RepK NDI进行翻转。这时候终端会有两种情况：
情况1：PDCCH的重复传输次数在PDCCH承载，这时候如果终端成功解调PDCCH但是无法解调PDSCH，终端回复NACK但是基站接收到ACK，那么终端继续能够按照旧的PDCCH重复传输次数进行解调。如果终端没有成功解调PDCCH，终端只能尝试去盲解PDCCH以及重复传输次数，这时候终端和基站对于PDCCH重复传 输次数理解上出现不一致。
情况2：PDCCH的重复传输次数在MAC CE承载并且在PDSCH上传输。这时候终端发送的HARQ-ACK的信息为NACK时，基站接收到的是ACK。这也会造成在基站在PDCCH重复传输次数更新的时间点实施新的PDCCH重复传输次数的时候，终端和基站对于PDCCH重复传输次数理解上出现不一致。
针对上述终端和基站对PDCCH重复传输次数理解不一致的情况，引入一个PDCCH重置reset机制，即，终端按照旧的PDCCH重复次数在PDCCH重复次数更新时间点接收PDCCH，如果接收失败，reset计数器加1并反馈NACK，当终端reset计数器达到预设次数N后，终端重置PDCCH Repk为默认值M，reset计数器清零，并向基站发起随机接入请求。
本申请实施例提供的信息传输方法，引入一个PDCCH reset机制，避免终端一直无法成功解调PDCCH，陷入死循环，提高了系统的可靠性。
基于上述任一实施例，所述向基站发起随机接入之后，还包括：
根据所述默认的PDCCH重复传输次数接收PDCCH信息。
具体来说，在本申请实施例中，终端进行随机接入过程结束后，基站将PDCCH重复传输次数重置为M，例如，M取值为4，基站按照PDCCH重复传输次数为M发送PDCCH，使得基站和终端对于PDCCH Repk进行重新设置，从而保持基站和终端对于PDCCH重复传输次数理解保持一致。
本申请实施例提供的信息传输方法，终端进行随机接入过程结束后，终端根据默认的PDCCH重复传输次数接收PDCCH信息，基站根据默认的PDCCH重复传输次数发送PDCCH信息，从而保持基站和终端对于PDCCH重复传输次数理解保持一致，提高了系统的可靠性。
基于上述任一实施例，所述默认的PDCCH重复传输次数是由基站预先通过广播信令发送给终端的。
具体来说，默认的PDCCH重复传输次数是由基站预先通过广播信令发送给终端的。
本申请实施例提供的信息传输方法，默认的PDCCH重复传输次数由基站预先通过广播信令发送给终端的终端，使终端在多次解调PDCCH失败之后，保持基站和终端对于PDCCH重复传输次数理解保持一致，提高了系统的可靠性。

步骤501、根据当前的信道质量确定物理下行控制信道PDCCH重复传输指示信息。

下面以两个具体的例子对上述各实施例中的方法进行说明：
例1：
本实施例通过PDCCH承载PDCCH重复传输指示信息(PDCCH RepK)，该指示信息用于更新PDCCH重复传输次数。UE确定了PDCCH传输次数从而就能够确定接收PDCCH时间窗。UE通过对接收窗内的PDCCH进行合并来提高PDCCH解调性能。PDCCH时间窗的大小与RepK相关，图6是本申请实施例提供的基于DCI指示的PDCCH重复机制示意图，如图6所示。如果RepK＝2，终端从发送确认信息ACK所在OFDM符号加上一个确定时间之后的第一个PDCCH MO开始按照m个PDCCH MO为一组进行划分PDCCH MO并按照m个PDCCH MO为一组进行接收PDCCH。对m个PDCCH MO计数处理有两种方法，具体如下：
方法1：对m个PDCCH MO所在的slot进行连续计数，如果遇到flexible slot或者UL slot一并计入到m个PDCCH MO之中，方法2：m个PDCCH MO是非连续的，在统计m个PDCCH MO的时候，不考虑flexible slot或者UL slot并且flexible slot或者UL slot不计入统计。图7是本申请实施例提供的PDCCH检测窗示意图，如图7所示。具体PDCCH重复传输更新机制如下：
(1)gNB在PDCCH MO中发送PDCCH重复传输指示信息RepK＝2用于将当前的1次传输更新为2次重复传输。
(2)gNB会在终端发送确认信息的所在OFDM符号加上T之后的第一个PDCCH MO实施RepK＝2，RepK＝2在PDCCH MO生效后，gNB在PDCCH detection window窗内，发送2次相同的PDCCH给 UE同时gNB在PDCCH MO中发送PDCCH重复传输指示信息RepK＝3用于将当前的PDCCH 2次重复传输更新为3次重复传输。
(3)gNB按照终端发送确认信息的时间加上T之后的第一个PDCCH MO实施RepK＝3，RepK＝3在PDCCH MO生效后，gNB在PDCCH detection window窗内，发送3次相同PDCCH给UE同时gNB在PDCCH MO中发送PDCCH重复传输指示信息RepK＝1用于将当前的PDCCH 3次重复传输更新为1次传输。
(4)gNB会在终端发送确认信息的所在OFDM符号加上T之后的第一个PDCCH MO实施RepK＝1，RepK＝1在PDCCH MO生效后，gNB在PDCCH detection window窗内，发送1次PDCCH给UE同时gNB在PDCCH MO中发送PDCCH重复传输指示信息RepK＝4用于将当前的PDCCH 1次传输更新为4次重复传输。
接下来需要确定PDCCH重复次数的生效起始点，图8是本申请实施例提供的PDCCH重复传输次数更新的生效起始点示意图，如图8所示，首先PDCCH的重复指示RepK是在DCI携带的，其次PDCCH重复次数的生效起始点是根据PDCCH所调度的PDSCH反馈信息确定。也就是当UE成功接收到PDCCH同时又成功解调PDSCH之后，UE会在PUCCH反馈一个ACK给gNB。gNB收到UE的ACK就会知道UE已经成功接收到携带PDCCH的重复指示RepK的PDCCH。因此gNB会在终端发送确认信息的所在OFDM符号加上T之后的第一个PDCCH MO实施新的PDCCH重复传输次数。对于UE，UE在发送携带PDCCH的重复指示RepK的PDCCH所调度的PDSCH反馈信息ACK之后，等待一个T(T>0，T主要为gNB预留的处理时间)，之后的第一个PDCCH MO实施新的PDCCH重复传输次数。目前设计的PDCCH Repk>0比特，例如，3比特，可以支持最小是单次传输，最大8次的PDCCH重复传输，其范围为[1,8]，具体定义见表1。

Figure PCTCN2021096604-appb-000001
T的起始时间参考点就是PUCCH反馈的ACK所在slot的最后一个OFDM符号者PUCCH反馈的ACK所在slot的第一个OFDM符号。如果PUCCH带有repetition的话，那么T(T的单位是时隙(Slot)或者OFDM符号)的起始时间参考点就是整个PUCCH repetition bundle的最后一个OFDM码元或者PUCCH repetition bundle的第一个OFDM符号。或者根据PUCCH反馈的ACK所在OFDM符号为起始时间参考点，如果PUCCH反馈的ACK占用几个OFDM符号，可以将占用的最后一个OFDM符号作为起始时间参考点或者根据第一个OFDM符号作为起始时间参考点。
图9是本申请实施例提供的PDCCH和PDSCH之间的K0的参考点示意图，如图9所示，下行调度DCI与其调度的PDSCH之间的Slot间隔K0的起始参考点为PDCCH检测window的最后一个PDCCH即PDCCH重复传输的最后一个PDCCH为起始参考点。
另外，为了解决在更新RepK的时候，防止基站和终端对于Repk理解不一致的情况主要分两种场景：
1、当终端发送的ACK给基站，但是基站接收到的NACK，然后基站依然按照旧的Repk发送给终端但是这时候终端会认为基站会按照更新的Repk发送PDCCH；
2、当终端发送的NACK给基站，但是基站接收到的ACK，这时候基站会按照更新的Repk发送给终端，但是终端却依然按照旧的Repk接收
引入一个新的指示信息域PDCCH Repk NDI，这个指示域的作用就是在Repk更新的时候进行翻转(从0变成1或者从1变成0)， 图10是本申请实施例提供的RepK NDI工作流程示意图，如图10所示。同时引入一个PDCCH reset机制即在基站收到若干次NACK之后，将PDCCH Repk重置为M，例如M取值为4，使得基站和终端对于PDCCH Repk进行重新设置从而保持基站和终端对于PDCCH重复传输次数理解保持一致。如果基站在PDCCH重复传输次数更新的时间点实施新的PDCCH重复传输次数地同时将PDCCH RepK NDI进行翻转。但是，当终端发送的HARQ-ACK的信息为ACK时，基站接收到的是NACK，这时候，基站会在PDCCH重复传输次数更新的时间点按照旧的PDCCH重复传输次数传输PDCCH同时PDCCH RepK NDI保持不变，当终端接收到PDCCH的时候，在检测PDCCH RepK NDI没有翻转就知道当前的PDCCH重复传输次数没有改变会按照旧的PDCCH重复传输次数接收后续的PDCCH。当终端发送的HARQ-ACK的信息为NACK时，基站接收到的是ACK，然后，基站在PDCCH重复传输次数更新的时间点实施新的PDCCH重复传输次数同时将PDCCH RepK NDI进行翻转。这时候终端会有两种情况，
情况1：PDCCH的重复传输次数在PDCCH承载，这时候如果终端成功解调PDCCH但是无法解调PDSCH，那么终端继续能够按照新的PDCCH重复传输次数进行解调。如果终端没有成功解调PDCCH，终端只能尝试去盲解PDCCH以及重复传输次数，这时候终端和基站对于PDCCH重复传输次数理解上出现不一致。
情况2：PDCCH的重复传输次数在MAC CE承载并且在PDSCH上传输。这时候终端发送的HARQ-ACK的信息为NACK时，基站接收到的是ACK。这也会造成在基站在PDCCH重复传输次数更新的时间点实施新的PDCCH重复传输次数的时候，终端和基站对于PDCCH重复传输次数理解上出现不一致。
对于上述终端和基站对于PDCCH重复传输次数理解上出现不一致的情况，引入一个PDCCH reset机制，即终端按照旧的PDCCH 重复次数在PDCCH重复次数更新时间点接收PDCCH，如果接收失败，reset计数器加1并反馈NACK，当终端reset计数器达到N次后，终端reset PDCCH Repk成默认值。reset计数器清零。终端重置PDCCH重复传输次数重置为M，并向基站发起随机接入请求，等随机接入过程结束后，基站将PDCCH重复传输次数重置为M，例如，M取值为4，基站按照PDCCH重复传输次数为M发送PDCCH，使得基站和终端对于PDCCH Repk进行重新设置从而保持基站和终端对于PDCCH重复传输次数理解保持一致。
图11是本申请实施例提供的基站和终端交互流程图，如图11所示，从网络角度上，一个完整的流程可以包含以下6个步骤：
1、基站首先发送PDCCH重复传输指示信息PDCCH RepK(用于更新PDCCH重复传输次数)Repk NDI＝0。
2、gNB会在终端发送确认信息ACK的所在OFDM符号加上T之后的第一个PDCCH MO实施更新的RepK，翻转RepK NDI从0到1。
3、基站发送翻转的NDI信息并且等待反馈信息。
4、基站接收到反馈信息后，如果反馈信息是ACK，基站按照新的PDDCH RepK发送PDCCH。
5、如果反馈信息是NACK，再次按照旧的PDCCH重复发送次数发送PDCCH并承载更新的PDCCH Repk给终端以及翻转RepK NDI设置为0，同时等待终端反馈。
6、基站在收到终端的随机接入请求后，完成随机接入流程并将PDCCH重复发送次数重置成默认值，然后发送PDCCH给终端。
从终端角度上，一个完整的流程可以包含以下9个步骤：
1、当终端接收到PDCCH重复传输指示信息PDCCH RepK之后，终端通过消息确认(ACK)机制(针对PDCCH调度的PDSCH的确认机制)发送确认信息ACK给基站。
2、终端在等待基站实施新的PDCCH重复传输次数期间，依然使用旧的PDCCH重复传输指示信息接收基站发送的PDCCH。
3、从终端发送确认信息ACK所在OFDM符号加上T时间之后，终端如果没有成功接收到PDCCH之后，就反馈NACK，reset计数器加1。
4、终端如果成功接收到PDCCH之后，首先check Repk NDI值，如果NDI没有翻转就是旧的PDCCH Repk值，终端成功解调PDSCH之后回复ACK并且使用旧的PDDCH Repk继续解调后续的PDCCH。
5、如果NDI翻转就是新的PDCCH Repk值，需要check是否收到了新的PDCCH Repk值，如果收到了，在成功解调PDSCH之后就回复ACK并且按照新的PDCCH Repk值继续解调后续的PDCCH，如果没有收到新的PDCCH Repk，就反馈NACK，reset计数器加1同时使用旧的PDDCH Repk继续解调后续的PDCCH。
6、终端reset计数器达到N次后，终端将PDCCH重复发送次数重置成默认值。reset计数器清零，并发起随机接入。
7、随机接入过程结束后，按照默认的PDCCH重复发送次数接收PDCCH。
另外当终端没有收到PDCCH重复传输指示信息PDCCH RepK的处理流程。
8、当终端没有接收到PDCCH重复传输指示信息PDCCH RepK之后，终端回复NACK eset计数器加1同时使用旧的PDDCH Repk继续解调后续的PDCCH。
9、终端reset计数器达到N次后，终端将PDCCH重复发送次数重置成默认值。reset计数器清零，并发起随机接入。
例2：
本实施例主要是通过MAC CE下发重复传输指示信息(PDCCH RepK)承载在PDSCH上，该指示信息用于更新PDCCH重复传输次 数。UE确定了PDCCH传输次数从而就能够确定接收PDCCH时间窗，图12是本申请实施例提供的基于MAC CE指示的PDCCH重复机制示意图，如图12所示，具体PDCCH重复传输更新机制如下：
(1)gNB在PDCCH MO i调度的PDSCH中发送PDCCH重复传输指示信息RepK＝2用于将当前的1次传输更新为2次重复传输。
(2)gNB会在终端发送确认信息的所在OFDM符号加上T之后的第一个PDCCH MO实施RepK＝2，RepK＝2在PDCCH MO j生效后，gNB在PDCCH detection window窗内，发送2次相同的PDCCH给UE同时gNB在PDCCH MO j调用的PDSCH中发送PDCCH重复传输指示信息RepK＝3用于将当前的PDCCH 2次重复传输更新为3次重复传输。
(3)gNB会在终端发送确认信息的所在OFDM符号加上T之后的第一个PDCCH MO实施RepK＝3，RepK＝3在PDCCH MO k生效后，gNB在PDCCH detection window窗内，发送3次相同PDCCH给UE同时gNB在PDCCH MO k调用的PDSCH中发送PDCCH重复传输指示信息RepK＝1用于将当前的PDCCH 3次重复传输更新为1次传输。
(4)gNB会在终端发送确认信息的所在OFDM符号加上T之后的第一个PDCCH MO实施RepK＝1，RepK＝1在PDCCH MO p生效后，gNB在PDCCH detection window窗内，发送1次PDCCH给UE同时gNB在PDCCH MO p调用的PDSCH中发送PDCCH重复传输指示信息RepK＝4用于将当前的PDCCH 1次传输更新为4次重复传输。
图13是本申请实施例提供的基于MAC CE指示的PDCCH重复传输次数更新的生效起始点示意图，如图13所示，确定PDCCH重复次数的生效起始点的方法如下：
首先PDCCH的重复指示RepK是在MAC CE携带并由PDSCH 承载，其次PDCCH重复次数的生效起始点是根据承载MAC CE(包含PDCCH重复传输指示)的PDSCH反馈信息确定。当UE成功解调PDSCH之后，UE会在PUCCH反馈一个ACK给gNB。gNB收到UE的ACK就会知道UE已经成功接收到携带PDCCH的重复指示RepK的MAC CE。因此gNB会在终端发送确认信息的所在的OFDM符号加上T之后的第一个PDCCH MO实施新的PDCCH重复传输次数。对于UE，UE在发送携带PDCCH的重复指示RepK的PDSCH反馈信息ACK之后，按照ACK所在的OFDM符号加上一个T(T>0，T主要为gNB预留的处理时间)，之后的第一个PDCCH MO实施新的PDCCH重复传输次数。目前设计的PDCCH Repk>0比特，图14是本申请实施例提供的MAC CE指示PDCCH重复传输的信息单元，图14中为4比特的PDCCH重复次数MAC CE信息单元，可以支持最小是单次传输，最大16次的PDCCH重复传输，其范围为[1,16]。
根据图9所示，下行调度DCI与其调度的PDSCH之间的Slot间隔K0的起始参考点为PDCCH检测window的最后一个PDCCH即PDCCH重复传输的最后一个PDCCH为起始参考点。
基于MAC CE指示的PDCCH重复传输次数，也需要引入一个新的指示信息域PDCCH Repk NDI和一个PDCCH reset机制来保持基站和终端对于PDCCH重复传输次数理解保持一致。
本申请实施例通过引入动态的PDCCH重复传输机制来增强PDCCH SINR从而降低PDCCH的解调门限。同时灵活的动态PDCCH重复传输机制可以根据信道条件动态调节PDCCH重复次数，从而在保证PDCCH解调性能的同时又有效的减少了网络的开销。
