具体实施方式
下面结合附图及实施例对本申请再作进一步详细的描述。
终端监听PDCCH的载波(英文可以表达为carrier)位置的方式主要包括以下两种：
第一种方式，自载波调度，终端在本载波上监听PDCCH；
第二种方式，跨载波调度，当一个载波被配置为跨载波调度时，会同时配置他的调度载波，即对该载波而言，需要在他的调度载波上该载波对应的搜索空间上监听他的PDCCH。
其中，可以通过媒体访问控制控制元素(MAC CE，也可以称为MAC-CE)激活或者去激活RRC配置的载波。
对于上述第一种方式，终端需要在所有激活的载波上盲检测PDCCH，以确定是否存在数据调度。对应上述第二种方式，终端需要在所有激活的调度载波上对应被调度载波的搜索空间中盲检测PDCCH。也就是说，无论是第一种方式还是第二种方式，对于终端来说，在MAC CE激活的载波均需要进行盲检测，这就意味着盲检测的能耗是随着激活的载波个数的增加而增加的，如此会大大增加终端的功耗。
因此，需要一种更加灵活的指示方式，以减少多载波工作情况下终端不必要的盲检测，同时能够实现灵活调度各个载波的目的。
另一方面，面对越来越丰富的频谱，例如FR1 6G以下频段，FR224.25GHz–52.6GHz频段，大于52.6G频段等，再考虑到低频的一些零散频谱，因此期望引入更灵活的频谱使用方式，能够更高效的使用所有的频谱，同时降低网络开销。
通过多个载波构成同一个小区，多个载波中只有一个载波作为锚点载波，多个载波中其他载波作为非载波的方式提高载波的利用率。在锚点载波上接收系统消息，寻呼消息等，其他载波可以供终端进行随机接入，进行数据传输。即，对于空闲态的终端，可见一个下行锚点载波，用于接收必要的系统消息，同时可见多个上行载波，能够在这些载波上选择接入；对于连接态的终端，希望能够进行载波调度的增强，使得载波的使用更加灵活，提高载波利用效率。
基于此，在本申请的各种实施例中，终端先通过在一个载波(即锚点载波)上接收一个不承载用于资源分配信息的DCI，获得接下来需要监听的载波信息，再在获得的载波信息对应的载波上进行控制信道的检测。
本申请实施例提供的方案，网络侧指示终端待检测PDCCH的载波，而不需要检测所有的载波，如此，能够动态地选择激活的载波数量，实现了载波的灵活调度，同时能够按需实现节能。
本申请实施例提供一种信息传输方法，应用于终端，如图1所示，该方法包括：
步骤101：在第一载波上接收DCI；所述DCI携带第一信息，且所述DCI不承载用于资源分配的信息；所述第一信息至少包括第二信息；所述第二信息指示待检测PDCCH的至少一个载波的载波信息；
步骤102：利用所述第二信息，确定所述待检测PDCCH的至少一个载波。
其中，实际应用时，所述终端可以称为UE，也可以称为用户。
本申请实施例中，可以通过多个载波构成同一个小区，在多个载波中只有一个锚点载波的情况下，所述终端可以通过锚点载波获取系统消息等，可以选择从非锚点载波进行随机接入。其中，本申请实施例对如何选择非锚点载波进行随机接入的过程不作限定。当所述终端通过一个非锚点载波进行随机接入后，这个非锚点载波可以称为主载波(英文可以表达为Pcarrier)，通过这个非锚点载波接收所述DCI。
这里，随着所述终端位置的变化，可以进行主载波的变化，比如基站基于所述终端的测量信号，发现终端的最佳主载波发生变化时，可以进行主载波的切换，相应地，接收所述DCI的第一载波也随着发生变化，即变为切换后的主载波。
其中，实际应用时，主载波的切换可以是半静态的，具体可通过RRC信令配置的方式来实现主载波的切换。
主载波的切换也可以是动态的，具体可通过DCI信令配置的方式来实现主载波的切换；其中，相应的配置信息可由所述DCI承载。
基于此，在一实施例中，所述第一信息还可以包含第五信息，所述第五信息指示载波索引；
利用所述第五信息确定后续接收所述DCI的第二载波。
示例性地，所述DCI中的M比特实现动态地主载波的切换；其中，M＝ceil(log2(N))，其中ceil()表示上取整操作，N对应于当前小区中关联的锚点载波和非锚点载波的个数。假设，当前小区中关联的锚点载波为1个，非锚点载波的个数为4，则N＝1+4＝5。
示例性地，所述DCI会绑定一个搜索空间，在所述第一载波上接收所述DCI时，所述终端可以基于绑定的搜索空间进行周期性的检测。
由于所述DCI携带指示待检测PDCCH的载波的载波信息，且不承载用于资源分配的信息，所述终端需要在所述DCI指示的载波上进行控制信道检测，因此，所述DCI可以称为第一级DCI，所述DCI指示的载波上检测的DCI可以称为第二级DCI。
实际应用时，所述第二信息可以表征待检测PDCCH的至少一个载波的载波标识，比如载波索引(英文表达为index)，即所述第二信息指示待检测PDCCH的至少一个载波中每个载波的载波索引，也就是说，所述第二信息的指示方式是待检测PDCCH的至少一个载波中每个载波的载波索引。所述终端可以基于所述第二信息指示的需要检测PDCCH的载波索引，确定对应的载波，再到对应的载波的激活BWP上检测对应的PDCCH。而对于那些不需要检测PDCCH的载波，所述终端则不再需要检测PDCCH，节省了终端在每个激活的载波上进行盲检测的复杂度，从而节省了终端能耗。
还可以通过比特位图(bitmap)指示待检测PDCCH的至少一个载波，因此，所述第二信息指示的指示方式可以是bitmap。所述终端可以基于bitmap确定对应的载波，再到对应的载波的激活BWP上检测对应的PDCCH。而对于那些不需要检测PDCCH的载波，所述终端则不再需要检测PDCCH，节省了终端在每个激活的载波上进行盲检测的复杂度，从而节省了终端能耗。
在一实施例中，所述第一信息还可以包含第三信息，所述第三信息指示所述第二信息的有效时间长度；
利用所述第三信息确定所述第二信息的有效时间长度。
其中，通过所述第三信息即通过时间长度指示，能够指示所述终端待检测的至少一个载波的生效时间。示例性地，假设所述DCI的检测周期为5ms，说明每间隔5ms才会检测一次所述DCI。同时，所述DCI中可以指示当前需要检测载波的状态持续多长时间，例如持续5ms，3ms或1ms等。
这里，实际应用时，可以先通过高层信令(比如RRC信令)配置多个时间长度，然后所述终端根据所述DCI的指示从配置的多个时间长度中选择一个生效时间长度。
基于此，在一实施例中，该方法还可以包括：
接收第四信息，所述第四信息指示多个候选有效时间长度；
利用所述第三信息从所述多个候选有效时间长度中确定一个作为所述第二信息的有效时间长度。
其中，所述终端可以通过高层信令接收所述第四信息。
实际应用时，当超过所述第三信息指示的时间长度，且仍未到下一个DCI检测时间点指示的生效时间的情况下，所述终端可以返回到一个默认的检测状态，比如检测全部载波(即在全部激活的载波上检测PDCCH)，或者只检测主载波(即只在主载波上检测PDCCH)。
基于此，在一实施例中，在第三指示信息指示的有效时间长度之外(英文可以表达为Expired)，在预先配置或预先定义的至少一个载波上检测所述PDCCH。
实际应用时，通常，终端在每个载波上进行控制信道检测，再读取控制信道中的BWP指示域，获得需要切换的BWP，这种方式下，网络侧需要在调度DCI中指示终端切换到下一个BWP，终端才能切换到下一个BWP上，因此终端需要等待调度DCI才能进行BWP的切换，如此，增加了BWP切换的中断时间。因此，在本申请实施例中，所述DCI还可以指示载波上的激活BWP，即在指示载波的同时还指示BWP，所述终端可以同时进行载波和BWP的调整工作，能够提前进行BWP的切换，从而节省了BWP切换的中断时间。
基于此，在一实施例中，所述第一信息还包含第六信息，所述第六信息指示所述至少一个载波中每个载波上的激活BWP；
利用所述第六信息确定所述至少一个载波中每个载波的激活BWP。
示例性地，如图2所示，上半部分为相关技术的方案，终端在时隙n检测载波0上的位于BWP1的控制信道，指示要进行BWP切换，切换到BWP2，假设BWP切换转换时间为2个时隙，那么在n+2时隙完成BWP切换。而在载波1上PDCCH的检测时隙为n+1，那么该PDCCH指示的BWP切换只能在n+3时隙才能完成。下半部分为本申请实施例的方案，通过周期性的主载波上的DCI指示需要检测的载波上的激活BWP，在时隙n的载波0的BWP1上检测到载波0和载波1的BWP切换指示，则不需要等待载波1的控制信道检测时刻，即时隙n+1，考虑到生效时间为2个时隙，则对于载波1能够在时隙n+2实现切换BWP上的传输，相比于相关技术的在时隙n+3完成切换，减少了传输时延。
实际应用时，如果所述终端本次漏检了所述DCI，按照相关技术，所述终端的默认(英文可以表达为default)行为是：基于上次收到的所述DCI的指示进行载波的控制信道检测。那么就会出现基站发送数据调度的载波和终端接收数据调度的载波的不一致。举个例子来说，假设通过MAC CE激活了载波1～10，上一次正确接收的所述DCI指示只需要检测载波1～3，本次DCI指示所述终端需要检测载波2～6，然而由于所述终端本次漏检了DCI，那么按照相关技术，所述终端仍然按照载波1～3来检测，那么载波4～6上的调度均会被漏检测。为了解决这种情况，可以为所述DCI设置HARQ反馈机制。
基于此，在一实施例中，所述第一信息还包含第七信息，所述第七信息指示所述DCI的HARQ-ACK的定时；
利用所述第六信息确定所述DCI的HARQ-ACK的反馈时隙；
在确定的反馈时隙上发送所述DCI的HARQ信息。
示例性地，所述DCI中的一个信息域，比如命名为DCI到HARQ反馈定时指示符(DCI-to-HARQ_feedback timing indicator)，所述信息域的信息指示所述DCI的HARQ-ACK的定时，通过所述DCI信息域的信息的指示，所述终端能够确定所述DCI的HARQ反馈的时隙，可以将这类非对应PDSCH的HARQ反馈比特串联在对应PDSCH的反馈比特后面构成HARQ反馈码本，当所述终端确定本次漏检测了所述DCI后，可以向基站反馈否定应答(NACK)或者不连续传输(DTX)，基站收到反馈后，对于上述例子，在后续的调度中可以避免将数据调度在载波4～6载波上，而是将数据调度到载波1～3上，从而避免基站和终端理解的不一致。
其中，所述终端可以基于在各个载波上的控制信息携带的DAI发现所述DCI是否漏检测了。
基于此，在一实施例中，所述第一信息还包含第八信息，所述第八信息为DAI，即所述第八信息指示DAI；
基于所述第八信息，确定所述DCI是否存在漏检，在确定所述DCI存在漏检的情况下，在预先配置或预先定义的至少一个载波上检测所述PDCCH，即基于默认行为进行载波的控制信道检测。
这里，基于DAI的检测机制是一种基站对同一个反馈窗口内的调度进行计数的机制，对于上述例子，通常来说，对于一个调度了PDSCH的PDCCH，该PDCCH携带的DAI能够让终端发现自身是否存在数据漏检。而本申请实施例中，第一载波上携带第一信息的DCI并不真正的调度数据传输，但为了让终端能够发现该DCI的漏检，在该DCI中也携带DAI信息，并与其他真正调度数据的DCI中的DAI统一计数，通过计数，所述终端能够发现自己接收了载波1～3的控制信道。如果DAI是不连续的，那么所述终端就可以判断出有些载波没有被自己检测，从而判断有可能是所述DCI漏检导致的。为了避免后续的继续漏检，所述终端会回到全部检测载波1～10的状态，即所述终端会回到将通过MAC CE激活的所有载波全被检测的状态，从而避免漏检。
相应地，本申请实施例还提供了一种信息传输方法，应用于网络设备，具体为基站，比如gNB，如图3所示，该方法包括：
步骤300：确定第一信息；
步骤301：在第一载波上向终端发送DCI；所述DCI携带第一信息，且所述DCI不承载用于资源分配的信息；所述第一信息至少包括第二信息；所述第二信息指示待检测PDCCH的至少一个载波的载波信息。
其中，实际应用时，所述网络设备根据需要确定所述第一信息，本申 请实施例对此不作限定。
在一实施例中，该方法还可以包括：
向所述终端发送第四信息，所述第四信息指示多个候选有效时间长度；其中，所述第三信息指示所述多个候选有效时间长度中的一个有效时间长度。
本申请实施例还提供了一种信息传输方法，如图4所示，该方法包括：
步骤401：网络设备在第一载波上向终端发送DCI；所述DCI携带第一信息，且所述DCI不承载用于资源分配的信息；所述第一信息至少包括第二信息；所述第二信息指示待检测PDCCH的至少一个载波的载波信息；
步骤402：所述终端接收到所述DCI后，利用所述第二信息，确定所述待检测PDCCH的至少一个载波。
这里，需要说明的是：所述终端和网络设备的具体处理过程已在上文详述，这里不再赘述。
利用本申请实施例提供的方案，还可以实现小区休眠(英文可以表达为cell dormancy)，具体地，如图5所示，当网络侧需要将某个载波用于休眠时，可以连续指示终端不需要在对应的载波上进行PDCCH检测，从终端的角度来说，由于不需要消耗功能在对应的载波上进行PDCCH检测，因此，这个载波就可以理解为处于休眠的状态了，即可以等效于实现了小区休眠的功能。其中，在图5中，在时隙n中通过DCI中的第二信息，指示终端在后续载波1，3，4上检测控制信道。则其他载波可以休眠。在时隙n+2指示终端后续在载波1，2，4，5上检测控制信道，其他载波可以休眠。
