Description

数据传输方法、装置、设备及存储介质 技术领域
本申请涉及移动通信技术领域，特别涉及一种数据传输方法、装置、设备及存储介质。
背景技术
免授权频谱是一种共享频谱，为了使得各个通信设备在免授权频谱上能够友好共存，一些国家或地区规定了使用免授权频谱需要满足的法规要求。如需要遵循先监听后使用的原则，且在一次数据传输中，传输时长不能超过最大信道占用时间，从而实现数据传输。
对于接入网设备来说，当通过监听抢占到信道后，通过PDCCH发送COT(Channel Occupation Time，信道占用时间)指示信息，该COT指示信息包括COT开始时间、COT结束时间、COT内的时隙个数等，之后，接入网设备通过PDCCH发送调度信息。对于UE(User Equipment，终端设备)来说，一般先以较小监听时机间隔的PDCCH(Physical Downlink Control CHannel，物理下行控制信道)检测方式检测PDCCH，以监听COT指示信息。当UE监听到COT指示信息后，根据该COT指示信息进入其他信道接收阶段，即从COT开始时间之后的第一个时隙的起始位置至COT结束时间内，采用监听时机间隔较大的PDCCH检测方式来检测PDCCH，以接收接入网设备发送的调度信息，从而根据该调度信息接收数据。另外，当检测时间达到COT结束时间后，该UE切换回以较小监听时机间隔的PDCCH检测方式检测PDCCH。
然而，无论UE当前采用何种PDCCH检测方式检测PDCCH，当UE一直未检测到COT指示信息时，就会一直采用当前的PDCCH检测方式进行检测，即始终无法切换至其他信道接收阶段，从而导致接入网设备与UE之间无法成功传输数据。

具体实施方式
在对本申请实施例提供的数据传输方法进行详细介绍之前，先对本申请实施例涉及的名词、实施环境和应用场景予以介绍。
首先，对本申请实施例涉及的名词进行介绍。
免授权频谱：通常被认为是共享频谱，即不同通信系统中的通信设备只要满足国家或地区在该免授权频谱上设置的法规要求，就可以使用该免授权频谱，而不需要向政府申请专有的频谱授权。
PDCCH：是一组物理资源粒子的集合，可以用于承载DCI(Downlink Control Information，下行控制信息)，还可以用于承载COT指示信息。根据其作用域不同，PDCCH信道承载的控制信息包括公共控制信息和专用控制信息。
搜索空间：定义了UE盲检的开始位置和PDCCH的搜索方式。
控制资源集(Control Resource Set，CORESET)：是一类时频资源集合，UE在对应的控制资源集进行PDCCH的检测。控制资源集由一组REG(Resource Element Group，资源粒子组)组成。
其次，对本申请实施例涉及的实施环境进行简单介绍。
请参考图1，该图1是根据一示例性实施例示出的一种实施环境的示意图，本申请实施例提供的数据传输方法可以应用于图1所示的实施环境中，该实施环境中主要包括UE 110和接入网设备120，该UE 110与该接入网设备120之间可以通过移动通信网络实现通信。
其中，该接入网设备120可以用于PDCCH信道发送。示例性地，接入网设备120可以在PDCCH信道上发送用于数据调度的信息，以指示UE 110如何进行上下文的数据传输。作为一种示例，在NR(New Radio，新无线)系统中，该接入网设备可以为eNB(evolutional Node B，演进型基站)等，本申请实施例对此不做限定。
其中，该UE 110主要用于执行本申请实施例提供的数据传输方法，比如，可以用于根据接入网设备120配置的PDCCH检测方式检测PDCCH，接收PDCCH传输的调度数据，从而实现上下文的传输数据等。
接下来，对本申请实施例涉及的应用场景进行简单介绍。
本申请实施例提供的数据传输方法应用于非授权频谱的信道场景中。为了让使用免授权频谱进行无线通信的各个通信系统在该免授权频谱上能够友好共存，一些国家或地区规定了使用免授权频谱必须满足的法规要求。如需遵循“LBT”(Listen-Before-Talk，先听后说)原则，即通信设备在免授权频谱的信道上进行信号发送前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，该通信设备才能进行信号发送；如果通信设备在免授权频谱的信道上的信道侦听结果为信道忙，该通信设备不能进行信号发送。且为了保证公平性，在一次传输中，通信设备使用免授权频谱的信道进行信号传输的时长不能超过MCOT(Maximum Channel Occupation Time，最大信道占用时间)。
其中，对于接入网设备来说，在成功抢占到信道后，即可进行信道发送。对于UE来说，对下行信道的接收一般包括三个阶段：Phase A、Phase B和Phase C，在不同阶段的信道监听时机可能不同。如图2所示，接下来，分别对该三个阶段进行简单介绍：
Phase A：在此阶段，为了能够尽快获取到COT指示信息，UE一般会在间隔较小的监听时机上监听PDCCH，如可以采用mini-slot based监听时机来进行监听，即监听周期小于一个时隙(slot)。
Phase B：当UE检测到COT指示信息时，可以确定接入网设备处于COT内，如图2所示，从该COT开始到第一个时隙的起始位置的阶段为该Phase B阶段。作为一种示例，在该Phase B阶段内，该UE可以继续采用Phase A阶段的PDCCH检测方式检测PDCCH，这里不做限定。
Phase C：是指从COT内的第一个时隙的起始位置到COT结束。在该Phase C阶段，UE在间隔较长的监听时机上监听PDCCH，如可以采用slot based监听时机来进行监听，即监听周期大于等于一个时隙。另外，在该阶段，UE接收接入网设备发送的调度信息，从而进行上下行的数据传输。
由此可见，对于UE来说，需要根据COT指示信息，确定从一个阶段切换至另一个阶段的时机。然而，如果UE漏检了COT指示信息，则无法正常进入其他信道检测阶段，比如无法从Phase C阶段进入Phase A阶段。为此，本申请实施例提供了一种数据传输方法，该方法可以解决这一问题，其具体实现请参见如下各个实施例。
在介绍完本申请实施例涉及的应用场景和实施环境后，接下来将结合附图对本申请实施例提供的数据传输方法进行详细介绍。
请参考图3，该图3是根据一示例性实施例示出的一种数据传输方法的流程图，该数据传输方法可以应用于上述图1所示的实施环境中，该数据传输方法可以包括如下几个实现步骤：
在步骤301中，根据第一PDCCH检测方式，检测第一PDCCH。
作为一种示例，该第一PDCCH检测方式对应的搜索空间的PDCCH监听周期大于等于 一个时隙，示例性地，该第一PDCCH检测方式对应的监听时机间隔包括M个时隙，M＞0。也可以认为该第一PDCCH检测方式为slot based监听时机的方式，即监听时机间隔是以时隙为单位。此时，该UE的监听时机间隔较大，也就是说，该第二PDCCH检测方式不是频繁监听，通常认为此时该UE处于Phase C阶段。
该第一PDCCH的检测结果可能包括多种情况，比如，可能会检测到该第一PDCCH，也可能未检测到该第一PDCCH。进一步地，当检测到该第一PDCCH时，该第一PDCCH可能携带COT指示信息，也可能未携带COT指示信息，或者，还可能携带数据调度的DCI。
在步骤302中，根据第一PDCCH的检测结果和第一时间信息，确定按照第一PDCCH检测方式检测第一PDCCH的结束时间。
作为一种示例，该第一时间信息可以用于指示按照第一PDCCH检测方式检测第一PDCCH的最晚结束时间。另外，至于具体何时为按照第一PDCCH检测方式检测第一PDCCH的结束时间，还可以结合第一PDCCH的检测结果来确定。
作为一种示例，根据该第一PDCCH的检测结果和第一时间信息，确定按照该第一PDCCH检测方式检测该第一PDCCH的结束时间，包括：当所述第一时间信息用于指示第一时刻时，若在该第一时刻到达时仍未在该第一PDCCH上接收到信道占用时间COT指示信息，则将该第一时刻确定为按照该第一PDCCH检测方式检测该第一PDCCH的结束时间。
也即是，当在该第一时刻到达之前一直未在第一PDCCH上接收到COT指示信息，且在该第一时刻到达时仍未在该第一PDCCH上接收到COT指示信息，说明UE可能漏检了或者接入网设备没有发COT指示信息，在该种情况下，可以换一种PDCCH检测方式来检测信道，结束当前的第一PDCCH检测方式。也即是，将该第一时刻确定为按照该第一PDCCH检测方式检测该第一PDCCH的结束时间，从而结束该第一PDCCH检测方式。
需要说明的是，上述仅是以该第一时间信息用于指示第一时刻为了进行说明，在另一实施例中，该第一时间信息还可以用于指示一个时长，在该种情况下，若在该第一时长内一直未在第一PDCCH上接收到COT指示信息，则将该第一时间信息指示的时长的结束点确定为检测该第一PDCCH的结束时间。
作为一种示例，在按照该第一PDCCH检测方式检测该第一PDCCH的结束时间之后，按照第二PDCCH检测方式，检测第二PDCCH。
其中，该第二PDCCH检测方式与该第一PDCCH检测方式不同。作为一种示例，该第二PDCCH检测方式与该第一PDCCH检测方式不同可以为以下任意一种情况：
第一种情况：该第一PDCCH检测方式与该第二PDCCH检测方式对应不同的搜索空间。
也就是说，该第一PDCCH检测方式检测与该第二PDCCH检测方式所检测的搜索空间不同或者CORESET不同，比如，该第一PDCCH检测方式检测的是PDCCH的第一搜索空间，该第二PDCCH检测方检测的是PDCCH的第二搜索空间。
第二种情况：该第一PDCCH检测方式与该第二PDCCH检测方式对应相同的搜索空间的不同PDCCH监听周期。
在该种实现方式中，可以将该第一PDCCH检测方式与该第二PDCCH检测方式对应相同的搜索空间，但这两种检测方式的监听周期不同，从而使得该第一PDCCH检测方式与该第二PDCCH检测方式不同。
作为一种示例，该第二PDCCH检测方式对应的搜索空间的PDCCH监听周期小于一个时隙，示例性地，该第二PDCCH检测方式对应的监听时机间隔包括N个符号symbol，0＜N＜7。也可以说，该第二PDCCH检测方式为mini-slot-based监听时机的方式，即监听时机间隔是以符号为单位，此时，该UE实际上采用频繁监听的方式来监听PDCCH，通常可以认为UE切换至Phase A阶段。
另外，该第一PDCCH检测方式与该第二PDCCH检测方式可以是由接入网设备预先配置给UE的，作为一种示例，该第一PDCCH检测方式和该第二PDCCH检测方式可以是由该接入网设备在UE随机接入后配置给该UE。
作为一种示例，按照第二PDCCH检测方式检测第二PDCCH的实现可以包括：UE在上述确定的结束时间之后的第一个时隙的边界，通过该第二PDCCH检测方式检测第二PDCCH，也就是说，切换至该第二PDCCH检测方式的时机可以为上述确定的结束时间之后的第一时隙的边界，或者，也可以说是上述确定的结束时间之后的最早的时隙边界。其中，结束时间之后的第一个时隙的边界可以通过第二PDCCH检测方式对应的PDCCH监听时机来确定。
作为一种示例，当在第一时间信息指示的时间到达之前接收到COT指示信息时，该UE可以根据该COT指示信息来确定按照第一PDCCH检测方式检测第一PDCCH的结束时间。或者，当在第一时间信息指示的时间到达之前接收到COT指示信息时，该UE也可以继续根据该第一时间信息指示的时间来确定按照第一PDCCH检测方式检测第一PDCCH的结束时间，本申请实施例对此不作具体限定。
在本申请实施例中，根据第一PDCCH检测方式检测第一PDCCH，根据该第一PDCCH的检测结果和第一时间信息，确定按照第一PDCCH检测方式检测所述第一PDCCH的结束时间。也即是，这里不再单纯依赖于COT指示信息来确定PDCCH检测方式的切换，而是根据检测结果和第一时间信息来确定，如此可以避免由于UE漏检COT指示信息等原因导致无法进入其他信道接收阶段的问题，提高了数据成功传输的概率。
请参考图4，该图4是根据另一示例性实施例示出的一种数据传输方法的流程示意图。该数据传输方法可以应用于图1所示的实施环境中，该数据传输方法可以包括如下几个实现步骤：
在步骤401中，根据第一PDCCH检测方式，检测第一PDCCH。
作为一种示例，该第一PDCCH检测方式对应的搜索空间的PDCCH监听周期大于等于一个时隙，示例性地，该第一PDCCH检测方式对应的监听时机间隔包括M个时隙，M＞0。也可以认为该第一PDCCH检测方式为slot based监听时机的方式，即监听时机间隔是以时隙为单位。此时，该UE的监听时机间隔较大，也就是说，该第二PDCCH检测方式不是频繁监听。通常认为此时该UE处于Phase C阶段，也即是，UE可能需要从Phase C阶段向Phase A阶段切换。
该第一PDCCH的检测结果可能包括多种情况，比如，可能会检测到该第一PDCCH，也可能未检测到该第一PDCCH。或者，当检测到第一PDCCH时，该第一PDCCH可能携带COT指示信息，也可能未携带COT指示信息，或者，还可能携带数据调度的DCI。
在步骤402中，根据该第一PDCCH的检测结果和第一时间信息，确定按照该第一PDCCH检测方式检测该第一PDCCH的结束时间。
作为一种示例，该第一时间信息包括第一时长，该第一时长是通过接收到的第一配置信息确定的或是预定义。
当该第一时长是通过接收到的第一配置信息确定时，该第一配置信息可以携带该第一时长，该第一配置信息由接入网设备发送的。作为一种示例，该第一配置信息可以为但不限于RRC(Radio Resource Control，无线资源控制)信令、广播信息，本申请实施例对此不作限定。
需要说明的是，上述仅是以该第一时长是通过接收到的第一配置信息确定的或是预定义的为例进行说明，在另一实施例中，该第一时长还可以是根据预设的规则确定的，本申请实施例对此不作限定。
作为一种示例，该第一时长的起始点由根据该第一PDCCH检测方式检测该第一PDCCH的目标监听时机确定，其中，在该目标监听时机未检测到携带公共DCI的第一PDCCH或者检测到携带目标DCI的第一PDCCH。
作为一种示例，该公共DCI包括COT指示信息，也即是，UE在该目标监听时机未检测到携带公共DCI的第一PDCCH包括：UE在该目标监听时机未检测到携带COT指示信息的第一PDCCH，此时，根据该目标监听时机，确定该第一时长的起始点。
作为一种示例，目标DCI包括用于数据调度的DCI，该目标DCI还可以称为UE特定的DCI，不包括COT指示信息。也即是，UE在该目标监听时机检测到携带目标DCI的第一PDCCH包括：UE在该目标监听时机检测到携带数据调度的DCI的第一PDCCH，也就是说，该UE在该目标监听时机可能会检测到第一PDCCH，但该第一PDCCH携带的是数据调度的DCI。此时，根据该目标监听时机，确定该第一时长的起始点。
示例性的，该第一时长的起始点为该第一PDCCH检测方式指示的目标监听时机的最后一个控制资源集的符号结束时间点。譬如，请参考图5，该第一时长的开始点为图5中的A时刻。
作为一种示例，根据该第一PDCCH的检测结果和第一时间信息，确定按照该第一PDCCH检测方式检测该第一PDCCH的结束时间的具体实现可以包括：当在该第一时长的结束点到达时仍未在该第一PDCCH上接收到信道占用时间COT指示信息时，将该第一时长的结束点确定为按照该第一PDCCH检测方式检测该第一PDCCH的结束时间。
譬如，请参考图5，从该第一时长的起始点，UE进行时间统计，在统计时间未超过该第一时长之前，UE采用第一PDCCH检测方式检测第一PDCCH。如果检测到COT指示信息，比如检测到携带COT指示信息的GC-PDCCH(Group Common PDCCH，组公共PDCCH)，则可以终止时间统计操作，该种情况下，该UE可以根据该COT指示信息来确定按照该第一PDCCH检测方式检测该第一PDCCH的结束时间。
反之，当统计时间达到该第一时长且在该第一时长内一直未接收时COT指示信息，则说明接入网设备可能未成功抢占到信道，或者UE漏检了第一PDCCH，在该种情况下，当统计时间达到该第一时长，比如，请参考图5，在B时刻达到该第一时长，在该种情况下，该UE将该第一时长的结束点确定为按照该第一PDCCH检测方式检测该第一PDCCH的结束时间。
在步骤403中，在按照该第一PDCCH检测方式检测该第一PDCCH的结束时间之后，按照第二PDCCH检测方式，检测第二PDCCH。
作为一种示例，请参考图5，UE在该第一时长之后的第一个时隙的边界，通过该第二PDCCH检测方式检测第二PDCCH。也就是说，切换至该第二PDCCH检测方式的时机可以为所确定的结束时间之后的第一时隙的边界，或者，也可以说是所确定的结束时间之后的最早的时隙边界。其中，该第一时长之后的第一个时隙的边界可以通过第二PDCCH检测方式确定的第二PDCCH监听时机来确定。
在本申请实施例中，根据第一PDCCH检测方式检测第一PDCCH，根据该第一PDCCH的检测结果和第一时间信息，确定按照第一PDCCH检测方式检测所述第一PDCCH的结束时间。也即是，这里不再单纯依赖于COT指示信息来确定PDCCH检测方式的切换，而是根据检测结果和第一时间信息来确定，如此可以避免由于UE漏检COT指示信息等原因导致无法进入其他信道接收阶段的问题，提高了数据成功传输的概率。
请参考图6，该图6是根据另一示例性实施例示出的一种数据传输方法的流程示意图。该数据传输方法可以应用于图1所示的实施环境中，该数据传输方法可以包括如下几个实现步骤：
在步骤601中，根据第一PDCCH检测方式，检测第一PDCCH。
作为一种示例，该第一PDCCH检测方式对应的搜索空间的PDCCH监听周期大于等于一个时隙，示例性地，该第一PDCCH检测方式对应的监听时机间隔包括M个时隙，M＞0。也可以认为该第一PDCCH检测方式为slot based监听时机的方式，即监听时机间隔是以时隙为单位。此时，该UE的监听时机间隔较大，也就是说，该第二PDCCH检测方式不是频繁监听。通常认为此时该UE当前处于Phase C阶段，也即是，UE可能需要从Phase C阶段向Phase A阶段切换。
该第一PDCCH的检测结果可能包括多种情况，比如，可能会检测到该第一PDCCH，也可能未检测到该第一PDCCH。或者，当检测到第一PDCCH时，该第一PDCCH可能携带 COT指示信息，也可能未携带COT指示信息，或者，还可能携带数据调度的DCI。
在步骤602中，当通过该第一PDCCH检测方式检测到第一PDCCH时，获取该第一PDCCH携带的目标DCI。
在这里，该第一时间信息可以通过该步骤602和该步骤603来确定，首先，当UE检测到第一PDCCH携带目标DCI时，可以获取该目标DCI。
在步骤603中，根据该目标DCI确定第一时间信息。
作为一种示例，当该目标DCI用于数据调度时，根据该目标DCI确定第一时间信息的实现可以包括：根据调度信息，确定该第一时间信息，该调度信息是由该目标DCI携带的或者是通过接收的第二配置信息确定的。
也即是说，当该目标DCI用于数据调度时，UE可以获取调度信息，以根据该调度信息来确定该第一时间信息。作为一种示例，该UE可以从目标DCI中获取该调度信息，即该调度信息由目标DCI携带，或者，还可以通过接收到的第二配置信息来获取该调度信息，该第二配置信息与该第一配置信息可以相同，也可以不同，示例性地，该第二配置信息可以为高层信令，即该调度信息还可以是接入网设备通过高层信令预先配置给UE的。作为一种示例，该高层信令可以为RRC信令等。
进一步地，由于该目标DCI可能是由PDSCH(Physical Downlink Shared Channel，物理下行共享信道)调度的，也可能是由PUSCH(Physical Uplink Shared Channel，物理上行共享信道)调度的，根据实际情况不同，根据该调度信息确定第一时间信息的具体实现可以包括如下几种可能的实现方式：
作为一种示例，当该目标DCI是由PDSCH调度时，获取该目标DCI中的用于指示PDCCH和PDSCH之间间隔的时隙个数的第一参数值和用于指示PDSCH和PUCCH(Physical Uplink Control Channel，物理上行控制信道)之间间隔的时隙个数的第二参数值，根据该第一参数值和该第二参数值，确定该第一时间信息。
当接入网设备通过下行授权(DL grant)的目标DCI调度下行数据传输时，会在调度信息中携带一个TDRA(Time Domain Resource Allocation，时间域资源分配)的域，该TDRA域通常为4bit，可以携带用于指示一个资源分配表格中的16个不同的行的配置信息，其中，每一行包含不同的资源分配组合。另外，该调度信息还可以包括用于指示PDCCH和PDSCH之间间隔的时隙个数的第一参数值，该第一参数值一般采用K0表示。另外，由于UE接收到PDSCH之后，需要反馈ACK(Acknowledgement，肯定确认)/NACK(Negative Acknowledgement，否定确认)，因此，接入网设备还通常会在该调度信息中进一步指示传输该PDSCH对应的ACK/NACK的时隙位置以及PUCCH资源，即该调度信息还包括用于指示PDSCH和PUCCH之间间隔的时隙个数的第二参数值，比如，该第二参数值可以表示为K1。例如，若该PDSCH在时隙n中传输，若该K1的取值为4，则表示对应的反馈信息ACK/NACK在时隙n+4中传输。进一步地，该PUCCH资源的配置信息可以用于指示预定义资源列表中的一个行，包括PUCCH在一个时隙内的时域资源、频域资源和扩频序列资源(该扩频序列资源针对某些PUCCH格式存在，某些PUCCH格式不需要)。
如此，UE可以从调度信息中获取第一参数值和第二参数值，即获取K0和K1，然后根据该K0和K1确定该第一时间信息。
作为一种示例，根据第一参数值和第二参数值确定该第一时间信息的具体实现可以包括：基于该第一参数值和第二参数值，通过公式(1)确定该第一时间信息：
T2＝K0+K1+1-S1-S2  (1)
其中，上述T2为第一时间信息，S1是指PDCCH时频资源所占的符号数，S2是指PUCCH占据的最后一个符号距离时隙结束位置之间的符号数。
当然，上述根据第一参数值和第二参数值确定该第一时间信息的实现方式仅是示例性的，在另一实施例中，还可以采用其他方式根据该第一参数值和第二参数值确定该第一时间信息，比如，还可以基于该第一参数值和第二参数值，通过如下公式(2)确定该第一时间信息：
T2＝K0+K1+1  (2)
需要说明的是，上述仅是以该第一参数值和第二参数值是根据调度信息确定为例进行说明，在另一实施例中，该第一参数值和第二参数值还可以是按照预定义的规则确定，本申请实施例对此不做限定。
作为一种示例，当目标DCI是由PUSCH调度时，获取该调度信息中的用于指示该目标DCI所在的时隙与PUSCH所在的时隙之间的偏移时隙个数的第三参数值；根据该第三参数值，确定该第一时间信息。
当接入网设备通过上行授权(UL grant)的目标DCI调度上行数据传输时，会在调度信息中携带一个TDRA的域，该TDRA域通常为4bit，可以携带用于指示一个资源分配表格中的16个不同的行的配置信息，其中，每一行包含不同的资源分配组合。另外，该调度信息还可以包括目标DCI所在的时隙与PUSCH所在的时隙之间的偏移时隙个数的第三参数值，该第三参数值一般采用K2表示。如此，UE可以从该调度信息中获取第三参数值，即获取K2，然后根据该K2确定该第一时间信息。
作为一种示例，根据第三参数值确定该第一时间信息的具体实现可以包括：基于该第三参数值，通过公式(3)确定该第一时间信息：
T2＝K2+1-S1-S2  (3)
其中，上述T2表示第一时间信息，S1是指PDCCH时频资源所占的符号数，S2是指PUCCH占据的最后一个符号距离时隙结束位置之间的符号数。
当然，上述根据第三参数值确定该第一时间信息的实现方式仅是示例性的，在另一实施例中，还可以采用其他方式根据该第三参数值确定该第一时间信息，比如，还可以基于该第三参数值，通过如下公式(4)确定该第一时间信息：
T2＝K2+1  (4)
作为一种示例，当该第一时间信息用于指示第三时长时，该第三时长的起始点可以为第一PDCCH的控制资源集的最后一个符号的结束时间点。譬如，如图7所示，该第三时长的起始点为图7中的A时刻。
作为一种示例，当该第一时间信息还可以指示一个目标时刻，譬如，请参考图8，该目标时刻为图8中的A时刻。
另外，需要说明的是，上述仅是以第三参数值是根据调度信息确定为例进行说明，在另一实施例中，该第三参数值还可以是按照预定义的规则确定的。
在步骤604中，根据该第一PDCCH的检测结果和第一时间信息，确定按照第一PDCCH检测方式检测第一PDCCH的结束时间。
作为一种示例，根据该第一PDCCH的检测结果和第一时间信息，确定按照该第一PDCCH检测方式检测该第一PDCCH的结束时间的具体实现可以包括：当该第一时间信息用于指示第三时长时，若在该第三时长的结束点到达时仍未在该第一PDCCH上接收到信道占用时间COT指示信息，则将该第三时长的结束点确定为按照该第一PDCCH检测方式检测该第一PDCCH的结束时间。
譬如，请参考图7，当该第一时间信息用于指示第三时长时，从该第三时长的开始点，UE进行时间统计，当统计时间为超过该第三时长之前，UE采用第一PDCCH检测方式检测第一PDCCH。如果检测到COT指示信息，比如检测到携带COT指示信息的GC-PDCCH，该种情况下，该UE可以根据该COT指示信息确定按照第一PDCCH检测方式检测该第一PDCCH的结束时间。反之，当统计时间达到该第三时长且在该第三时长内一直未接收时COT指示信息，则说明接入网设备可能未成功抢占到信道，或者UE漏检了第一PDCCH，在该种情况下，当统计时间达到第三时长，比如，请参考图7，在B时刻达到该第三时长，在该种情况下，该UE将该第三时长的结束点B确定为按照第一PDCCH检测方式检测该第一PDCCH的结束时间。
作为一种示例，根据该第一PDCCH的检测结果和第一时间信息，确定按照该第一PDCCH 检测方式检测该第一PDCCH的结束时间的具体实现可以包括：当该第一时间信息用于指示目标时刻时，若在该目标时刻到达时仍未在该第一PDCCH上接收到信道占用时间COT指示信息，则将该目标时刻确定为按照该第一PDCCH检测方式检测该第一PDCCH的结束时间。
如，请参考图8，当该第一时间信息指示的为一个目标时刻时，如果UE在该目标时刻之前检测到COT指示信息，比如检测到携带COT指示信息的GC-PDCCH，则可以根据该COT指示信息，确定按照第一PDCCH检测方式检测该第一PDCCH的结束时间。反之，若在到达目标时刻时仍一直未检测到COT指示信息，则说明接入网设备可能未成功抢占到信道，或者UE漏检了该第一PDCCH，在该种情况下，当到达该目标时刻，比如，到达图8中的A时刻，在该种情况下，该UE将该图8中的A时刻确定为按照第一PDCCH检测方式检测该第一PDCCH的结束时间。
在步骤605中，在按照该第一PDCCH检测方式检测该第一PDCCH的结束时间之后，按照第二PDCCH检测方式，检测第二PDCCH。
作为一种示例，请参考图7或8，UE在该第一时间信息之后的第一个时隙的边界，通过该第二PDCCH检测方式检测第二PDCCH。也就是说，切换至该第二PDCCH检测方式的时机可以为所确定的结束时间之后的第一时隙的边界，或者，也可以说是所确定的结束时间之后的最早的时隙边界。其中，该第一时长之后的第一个时隙的边界可以通过第二PDCCH检测方式确定的第二PDCCH监听时机来确定。
在本申请实施例中，根据第一PDCCH检测方式检测第一PDCCH，根据该第一PDCCH的检测结果和第一时间信息，确定按照第一PDCCH检测方式检测所述第一PDCCH的结束时间。也即是，这里不再单纯依赖于COT指示信息来确定PDCCH检测方式的切换，而是根据检测结果和第一时间信息来确定，如此可以避免由于UE漏检COT指示信息等原因导致无法进入其他信道接收阶段的问题，提高了数据成功传输的概率。
请参考图9，该图9是根据另一示例性实施例示出的一种数据传输方法的流程示意图。该数据传输方法可以应用于图1所示的实施环境中，该数据传输方法可以包括如下几个实现步骤：
在步骤901中，根据第一PDCCH检测方式，检测第一PDCCH。
作为一种示例，该第一PDCCH检测方式对应的搜索空间的PDCCH监听周期大于等于一个时隙，示例性地，该第一PDCCH检测方式对应的监听时机间隔包括M个时隙，M＞0。也可以认为该第一PDCCH检测方式为slot based监听时机的方式，即监听时机间隔是以时隙为单位。此时，该UE的监听时机间隔较大，也就是说，该第二PDCCH检测方式不是频繁监听。通常认为此时该UE当前处于Phase C阶段，也即是，UE可能需要从Phase C阶段向Phase A阶段切换。
该第一PDCCH的检测结果可能包括多种情况，比如，可能会检测到该第一PDCCH，也可能未检测到该第一PDCCH。或者，当检测到第一PDCCH时，该第一PDCCH可能携带COT指示信息，也可能未携带COT指示信息，或者，还可能携带数据调度的DCI。
在步骤902中，当通过该第一PDCCH检测方式检测到第一PDCCH时，获取该第一PDCCH携带的目标DCI。
在这里，该第一时间信息可以通过该步骤902和该步骤903来确定，首先，当UE检测到第一PDCCH携带目标DCI时，可以获取该目标DCI。
在步骤903中，根据该目标DCI确定第一时间信息。
作为一种示例，根据该目标DCI中的指示信息确定该第一时间信息。也即是，相比于已有的通信系统技术，该目标DCI中新增了一个用于指示该第一PDCCH所在的时隙与第一时间信息之间的时隙偏移的指示信息，UE获取该指示信息，比如，假设该第一PDCCH所在的时隙为n，该指示信息为4，则可以确定该第一时间信息为n+4。
作为一种示例，该指示信息为第二时长，该第二时长用于确定该第一时间信息，该第二 时长为预定义的至少一个第二时长中的任一个。
也就是说，该指示信息可以直接为一个时长信息，并且，可以预先定义至少一个时长信息，该指示信息可以包括预定义的至少一个时长信息中的任一个。
在步骤904中，根据该第一PDCCH的检测结果和第一时间信息，确定按照第一PDCCH检测方式检测第一PDCCH的结束时间。
作为一种示例，根据该第一PDCCH的检测结果和第一时间信息，确定按照该第一PDCCH检测方式检测该第一PDCCH的结束时间的具体实现可以包括：当该第一时间信息用于指示第一时刻时，若在该第一时刻到达时仍未在该第一PDCCH上接收到信道占用时间COT指示信息，则将该第一时刻确定为按照该第一PDCCH检测方式检测该第一PDCCH的结束时间。
如果UE在该第一时刻到达之前检测到COT指示信息，比如检测到携带COT指示信息的GC-PDCCH，则可以根据该COT指示信息确定按照该第一PDCCH检测方式检测该第一PDCCH的结束时间。反之，若在到达该第一时刻仍未检测到COT指示信息，则说明接入网设备可能未成功抢占到信道，或者UE漏检了第一PDCCH，在该种情况下，当到达该第一时刻，比如，请参考图8，在达到A时刻时，该UE将该第一时刻(如A时刻)确定为按照该第一PDCCH检测方式检测该第一PDCCH的结束时间。
在步骤905中，在按照该第一PDCCH检测方式检测该第一PDCCH的结束时间之后，按照第二PDCCH检测方式，检测第二PDCCH。
作为一种示例，请参考图8，UE在该第一时间信息之后的第一个时隙的边界，通过该第二PDCCH检测方式检测第二PDCCH。也就是说，切换至该第二PDCCH检测方式的时机可以为所确定的结束时间之后的第一时隙的边界，或者，也可以说是所确定的结束时间之后的最早的时隙边界。其中，该第一时间信息之后的第一个时隙的边界可以通过第二PDCCH检测方式确定的第二PDCCH监听时机来确定。
在本申请实施例中，根据第一PDCCH检测方式检测第一PDCCH，根据该第一PDCCH的检测结果和第一时间信息，确定按照第一PDCCH检测方式检测所述第一PDCCH的结束时间。也即是，这里不再单纯依赖于COT指示信息来确定PDCCH检测方式的切换，而是根据检测结果和第一时间信息来确定，如此可以避免由于UE漏检COT指示信息等原因导致无法进入其他信道接收阶段的问题，提高了数据成功传输的概率。
请参考图10，该图10是根据一示例性实施例示出的一种数据传输方法的流程图，该数据传输方法可以应用于图1所述的实施环境中，该数据传输方法可以包括：
在步骤1001中，检测解调参考信号DMRS。
UE在检测PDCCH之前，可以先检测DMRS(Demodulation Reference Signal，解调参考信号)。示例性的，该DMRS可以为宽带DMRS。
进一步地，如果UE检测到DMRS，则说明当前处于COT内，也即是，接入网设备成功抢占信道，否则，如果UE未检测到DMRS，说明当前未处于COT内。
在步骤1002中，根据该DMRS的检测结果和第二时间信息，确定按照第一PDCCH检测方式检测第一PDCCH的结束时间。
示例性的，该第二时间信息为通过接收的第三配置信息确定的或是预定义的。进一步地，当该第二时间信息为通过接收的第三配置信息确定时，该第三配置信息可以由接入网设备发送的，比如可以为RRC信令等。该第三配置信息可以与该第一配置信息和第二配置信息不同，或者，也可以与该第一配置信息或者第二配置信息相同。
作为一种示例，根据该DMRS的检测结果和第二时间信息，确定按照第一PDCCH检测方式检测第一PDCCH的结束时间的具体实现可以包括：当该第二时间信息用于指示第二时刻时，若检测到该DMRS，则将根据该第二时刻确定为按照该第一PDCCH检测方式检测该第一PDCCH的结束时间。
需要说明的是，上述仅是以该第二时间信息用于指示第二时刻为例进行说明，在另一实 施例中，该第二时间信息还可以用于指示一个时长，在该种情况下，若在该第二时间信息指示的时长内检测到该DMRS，则将该第二时间信息指示的时长的结束点确定为按照该第一PDCCH检测方式检测该第一PDCCH的结束时间。
当检测到该DMRS后，可以根据启动该第二时间信息，作为一种示例，当该第二时间信息指示的是一个时长时，该第二时间信息指示的时长的起始点可以为检测到DMRS的符号位置或者其相邻的符号位置。之后，可以根据该第二信息来确定按照该第一PDCCH检测方式检测该第一PDCCH的结束时间。
进一步地，在该第一PDCCH检测方式检测该第一PDCCH的结束时间之后，按照目标检测方式，检测DMRS。
也就是说，该UE在在该第一PDCCH检测方式检测该第一PDCCH的结束时间之后，可以继续按照目标检测方式检测DMRS，而不是直接按照第二PDCCH检测方式检测第二PDCCH。示例性地，当该UE按照目标检测方式检测到DMRS时，可以按照第二PDCCH检测方式检测第二PDCCH，即进入Phase A阶段。
在本申请实施例中，检测DMRS，根据该DMRS的检测结果和第二时间信息，确定按照第一PDCCH检测方式检测第一PDCCH的结束时间。也即是，这里不再单纯依赖于COT指示信息来确定PDCCH检测方式的切换，而是该DMRS的检测结果和第二时间信息来确定，如此可以避免由于UE漏检COT指示信息等原因导致无法进入其他信道接收阶段的问题，提高了数据成功传输的概率。
请参考图11，该图11是根据另一示例性实施例示出的一种数据传输方法的流程示意图。该数据传输方法可以应用于图1所示的实施环境中，该数据传输方法可以包括如下几个实现步骤：
在步骤1101中，根据第二PDCCH检测方式检测第二PDCCH。
其中，该第二PDCCH检测方式的监听时机间隔小于第一PDCCH检测方式的监听时机间隔时，此时，通常认为是UE当前处于Phase A阶段，需要从Phase A阶段向Phase C阶段切换。
在步骤1102中，根据该第二PDCCH的检测结果和第三时间信息，确定从该第二PDCCH检测方式切换至第一PDCCH检测方式。
为了避免UE由于漏检COT指示信息导致一直处于Phase A阶段，无法进入Phase C阶段，可以设定第三时间信息。
示例性的，若在第三时间信息指示的时间内未在第二PDCCH上接收到COT指示信息，从当前的第二PDCCH检测方式切换至第一PDCCH检测方式，该第二PDCCH检测方式与该第一PDCCH检测方式不同。
作为一种示例，该第三时间信息可以为通过接收到的第四配置信息确定的或是预定义的。进一步地，该第四配置信息由接入网设备发送，该第四配置信息可以为但不限于RRC信令、广播信息，本申请实施例对此不作限定。
该第四配置信息可以分别与第一配置信息、第二配置信息和第三配置信息不同，或者，该第四配置信息也可以与第一配置信息、第二配置信息或第三配置信息相同，本申请实施例对此不做限定。
需要说明的是，上述仅是以该第三时间信息是通过接收到的第四配置信息确定的或是预定义的为例进行说明，在另一实施例中，该第三时间信息还可以是根据预设的规则确定的，本申请实施例对此不作限定。
作为一种示例，该第三时间信息指示的时长的开始点为通过该第二PDCCH检测方式对第二PDCCH进行检测的开始时间。譬如，请参考图12，该第三时间信息指示的时长的开始点为图12中的A时刻。
从该第三时间信息指示的时长的开始点，UE进行时间统计，若统计时间未超过该第三时 间信息指示的时长，则UE采用第二PDCCH检测方式检测第二PDCCH。如果检测到COT指示信息，可以终止时间统计操作，该种情况下，该UE可以根据该COT指示信息从Phase A阶段切换至Phase C阶段，因此，可以不再根据该第三时间信息指示的时长来进行后续的信道接收方式的切换。
反之，当统计时间达到该第三时间信息指示的时长且在该时长内一直未接收时COT指示信息，则说明接入网设备可能未成功抢占到信道，或者UE漏检了第二PDCCH，在该种情况下，当统计时间达到该时长，如图12中的B时刻，该UE从当前的第二PDCCH检测方式切换至第一PDCCH检测方式，即从Phase A阶段切换至Phase C阶段。
值得一提的是，一方面，UE在接入网设备长时间没有抢占到信道的情况下，可以减少PDCCH的检测频次，从而节省UE的耗电；另一方面，也可以避免因PDCCH的漏检造成UE接收PDCCH的行为无法相应的改变的问题，即可以避免UE一直按照第二PDCCH检测方式检测第二PDCCH。
在步骤1103中，通过第一PDCCH检测方式检测第一PDCCH。
作为一种示例，请参考图12，UE在该第三时间信息指示的时长之后的第一个时隙的边界，通过该第一PDCCH检测方式对PDCCH进行检测，也就是说，切换至该第一PDCCH检测方式的时机可以为预定时间之后的第一时隙的边界，或者，也可以说是该预定时间之后的最早的时隙边界。其中，该第三时间信息指示的时长之后的第一个时隙的边界是通过第一PDCCH检测方式确定的PDCCH监听时机。
在本申请实施例中，当在第三时间信息指示的时间内未检测到第二PDCCH上的COT指示信息，UE不再采用当前的第二PDCCH检测方式检测，而是切换至第一PDCCH检测方式检测，以避免由于UE漏检COT指示信息等原因导致无法进入其他信道接收阶段，从而使得数据能够成功传输。
