具体实施方式
为了能够更加详尽地了解本申请实施例的特点与技术内容，下面结合附图对本申请实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本申请实施例。
首先，对本申请中涉及的概念做出解释：
1、PDCCH的设计机制
在5G新空口(new radio，NR)和其他系统如长期演进技术(Long Term  Evolution，LTE)的控制信道采用的是单时隙多符号的传输方式。一个PDCCH的传输可在一个搜索空间(Search Space，SS)中传输，SS映射在某一控制信道资源集合(Control Resource Set，CORESET)中。
具体的，PDCCH、SS、CORESET和带宽部分(Bandwidth part，BWP)之间的映射关系如下：一个PDCCH映射在一个SS中，一个SS映射在一个CORESET中，一个CORESET中映射在一个BWP中，即：PDCCH->SS->CORESET->BWP
2、NR BWP对带宽资源的定义
NR可以支持较大的工作带宽。但不要求终端设备总是工作在完整的系统带宽上。也不需要终端设备知道系统带宽。这样可以根据不同业务对带宽的不同需求接入。对终端设备的节能更加友好。为此，NR引入了BWP的概念。在一个小区里，终端设备可以配置最多4个BWP。
对于终端设备的每一个BWP，网络可以配置最多10个PDCCH search space；配置最多3个PDCCH CORESET。
3、控制资源集合CORESET
在5G NR系统中，引入了CORESET的概念，用于定义承载控制信息的时频资源集合，UE在该时频资源集合中检测NR-PDCCH信道，以获得调度信息。CORESET的配置信息主要包含以下等信息：
CORESET占用的物理资源块(Physical Resource Block，PRB)；
CORESET占用的连续正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号数目；
PDCCH解调参考信号(Demodulation Reference Signal，DMRS)扰码序列初始值；
频率域的预编码粒度；
控制候选单元(Control Candidate Element，CCE)与资源粒子组(resource Element Group，REG)之间的映射类型；
天线端口的准共址信息，用于指示用于PDCCH接收的DMRS天线端口的准共址信息，该信息从高层信令配置的TCI-States中选取一个TCI state并通过媒体接入控制(Media Access Control，MAC)控制单元(Control Element，CE)配置给终端设备；
指示下行控制信息(Downlink control information，DCI)format 1_1中是否出现传输配置指示(transmission configuration indication，TCI)域。
4、NR的PDCCH SS Set
NR UE的PDCCH监听是在PDCCH search space set中进行的。由于每一个不同的聚合等级的candidates构成一个Search Space，一个Search Space Set下多个Search Space构成。PDCCH search space set的配置信息包含如下等信息：
Search space set ID；
Control Resource Set Id指示control resource set的配置的ID，配置PDCCH search space set的时频资源；
监听的时隙的周期以及在周期内的偏置；目前NR支持的周期包括1、2、4、5、8、10、16、20、40、80、160、320、640、1280、2560个时隙；
所在监听时隙的起始符号；
Duration指示在PDCCH search space set一个周期起点连续监听的时隙个数；
Monitoring Symbols Within Slot指示在PDCCH监听的时隙内哪些符号上进行PDCCH监听；
候选PDCCH指示PDCCH candidate的配置信息。其中，包含每一聚合等级下候选PDCCH数量的信息；
Search space的类型：指示PDCCH search space是common search space还是UE-specific search space。
目前，PDCCH可以在某一候选PDCCH传输，根据现在的PDCCH search  space set配置，如果类型为是common search space，最大的传输聚合等级为16，即一个候选PDCCH有16个CCE作为传输的资源。而对于UE-specific search space，最大只能配给一个候选PDCCH8个CCE。由于common search space的资源多，编码增益可能更高，因此覆盖强于UE-specific search space。
对于现有技术中存在的问题，具体可通过以下实施例进行解决。
实施例一
本申请实施例提供了一种信息传输方法，应用于终端设备，图1为本申请实施例提供的一种信息传输方法流程图一，如图1所示，信息传输方法可以包括：
S100、接收多个第一物理下行控制信道PDCCH，多个第一PDCCH用于调度相同的第一数据。

在本申请实施例中，终端设备接收多个第一PDCCH的方式，具体为终端设备利用无线通信的方式接收多个第一PDCCH。
在本申请实施例中，第一PDCCH承载网络侧发送给终端设备的下行控制信息，这些下行控制信息包括上下行数据传输相关的控制信息，如数据传输的资源分配信息、时隙内上/下行资源的格式信息，以及上行数据信道和信号的功率控制信息等，动态时隙配置信息，资源抢占信息等。终端设备在接收到该第一PDCCH的情况下，终端设备可以根据该第一PDCCH中承载的下行控制信息调度第一数据。
在本申请实施例中，多个第一PDCCH承载的下行控制信息相同。
在本申请实施例中，多个第一PDCCH的数量为正整数，示例性的，多个第一PDCCH的数量可以为4个；多个第一PDCCH的数量也可以为5个；多个第一PDCCH的数量还可以为6个，具体的可根据实际情况进行确定，本申请实施例对此不作限定。
在本申请实施例中，第一数据包括物理上行共享信道PUSCH数据或者物理下行共享PDSCH数据。
在本申请实施例中，终端设备接收的多个第一PDCCH可用于调度PUSCH数据；终端设备接收的多个第一PDCCH也可用于调度PDSCH数据，具体的可根据实际情况进行确定，本申请实施例对此不作限定。
在本申请实施例中，终端设备接收多个第一PDCCH包括：终端设备确定第一PDCCH的重复次数N，终端设备根据该重复次数N接收多个第一PDCCH。
需要说明的是，第一PDCCH的重复次数N为重复传输第一PDCCH的次数，其中，该重复次数N为不小于2的正整数。
在本申请实施例中，多个第一PDCCH的数量就是第一PDCCH的重复次数N。
在本申请实施例中，终端设备根据该重复次数N接收多个第一PDCCH的方式可以为：若重复次数N为4次，则终端设备接收4个第一PDCCH；若重复次数N为5次，则终端设备接收5个第一PDCCH；若重复次数N为6次，则终端设备接收6个第一PDCCH，具体的可根据实际情况进行确定，本申请实施例对此不作限定。
在本申请实施例中，重复次数N携带在第一PDCCH中，终端设备确定第一PDCCH的重复次数N，包括：终端设备依次解码接收到的第一PDCCH，若终端设备解码到第K个第一PDCCH时成功解码，则终端设备就可以从该第K个PDCCH中得到重复次数N。
需要说明的是，K为不大于N的正整数。
在本本申请实施例中，终端设备接收到第一PDCCH时，终端设备就对该第一PDCCH进行解码，当终端设备接收到第K个PDCCH时，终端设备就开始对第K个PDCCH进行解码，若终端设备对该第K个PDCCH解码成功时，终端设备就可以从该第K个PDCCH中得到重复次数N。
示例性的，重复次数N可以为5，K可以为2，当终端设备接收到网络侧发送的第一PDCCH时，终端设备就开始对该第一PDCCH进行解码，当终端设备对第1个第一PDCCH解码未成功，且终端设备对第2个第一PDCCH解码成功时，终端设备就可以从第2个第一PDCCH中得到重复次数N为5的信息。
在本申请实施例中，终端设备对该多个第一PDCCH进行解码的方式，可以为合并解码，也可以为联合解码，具体的可根据实际情况进行确定，本申请实施例对此不作限定。
在本申请实施例中，终端设备在解码到第K个第一PDCCH时成功解码，得到重复次数N的过程，包括：终端设备在解码到第K个第一PDCCH时成功解码，则终端设备就可以根据该第K个第一PDCCH中得到下行控制信息DCI；该DCI中包括指示域，该指示域用于指示重复次数N。
在本申请实施例中，第一PDCCH中包括DCI，该DCI中包括指示域，指示域中设置有重复次数N，终端设备通过对第K个第一PDCCH进行解码，终端设备就可以得到DCI的指示域得到重复次数N。
在本申请实施例中，指示域包括比特值，终端设备根据该比特值，可以确定出重复次数N。
在本申请实施例中，指示域中设置有比特值，该比特值可以为数字形式的信息，该比特值也可以为符号形式的信息，具体的可根据实际情况进行确定，本申请实施例对此不作限定。
在本申请实施例中，终端设备确定重复次数N的方式，还可以是终端 设备根据预设比特值和预设可选值之间的映射关系，确定出该比特值对应的可选值，终端设备得到可选值之后，终端设备就可以将该可选值作为重复次数N。
在本申请实施例中，终端设备中设置有预设比特值和预设可选值之间的映射关系，当终端设备得到比特值时，终端设备就可以从预设比特值和预设可选值之间的映射关系中确定出与该比特值匹配的第一预设比特值，并将该第一预设比特值对应的第一预设可选值作为可选值，从而得到重复次数N。
在本申请实施例中，预设比特值和预设可选值之间的映射关系可以是网络侧发送至终端设备的信息，预设比特值和预设可选值之间的映射关系可以是终端设备中预设的信息，具体的可根据实际情况进行确定，本申请实施例对此不作限定。
在本申请实施例中，终端设备根据重复次数N，接收多个第一PDCCH的过程，包括：终端设备继续接收多个第一PDCCH中剩余的N-K个第一PDCCH。
在本申请实施例中，在终端设备对第K个第一PDCCH成功解码，得到第一PDCCH的重复次数N的情况下，终端设备就继续接收多个第一PDCCH中剩余的N-K个第一PDCCH。
在本申请实施例中，K为小于等于N的正整数。
在本申请实施例中，在K小于N的情况下，终端设备就继续接收多个第一PDCCH中剩余的N-K个第一PDCCH；在K等于N的情况下，终端设备就不再继续接收第一PDCCH。
示例性的，当终端设备对第2个第一PDCCH成功解码，得到第一PDCCH的重复次数N为5的情况下，则终端设备就继续接收多个第一PDCCH中剩余的3个第一PDCCH；当终端设备对第4个第一PDCCH成功解码，得到第一PDCCH的重复次数N为4的情况下，则终端设备就不 再继续解码剩余第一PDCCH。
在本申请实施例中，终端设备继续接收多个第一PDCCH中的剩余N-K个第一PDCCH之后，终端设备就不对该剩余的N-K个第一PDCCH进行解码。
可以理解的是，通过设置多个第一PDCCH的多时隙重复传输时的重复次数N，在终端设备对第K个第一PDCCH成功解码，终端设备确定出重复次数N的情况下，终端设备就可以停止解码多个第一PDCCH中的剩余第N-K个PDCCH，节省了终端设备与网络通信时的信道资源，提高了多个第一PDCCH的传输速度。
在本申请实施例中，终端设备还可以接收网络侧的第一指示信息，该第一指示信息用于指示第一PDCCH的最大解码次数M；若终端设备依次解码了M个接收到的第一PDCCH后，终端设备仍未成功解码该第一PDCCH，则终端设备停止对该第一PDCCH的解码。
需要说明的是，第一指示信息可以为网络侧为终端设备配置的信息，配置的信息中包括第一PDCCH的最大解码次数M，终端设备可直接从该配置的信息中得到第一PDCCH的最大解码次数M。
在本申请实施例中，终端设备可根据配置的第一PDCCH的最大解码次数M，来确定是否对继续该第一PDCCH的进行解码。
在本申请实施例中，第一指示信息可以是终端设备与网络进行连接时，网络侧发送至终端设备的信息，也可以是终端设备首次接收到第一PDCCH时接收到的信息，具体的可根据实际情况进行确定，本申请实施例对此不作限定。
在本申请实施例中，第一PDCCH的最大解码次数M可以与第一PDCCH的重复次数N相同，第一PDCCH的最大解码次数M可以小于第一PDCCH的重复次数N，具体的可根据实际情况进行确定，本申请实施例对此不作限定。

在本申请实施例中，终端设备根据重复次数N，接收多个第一PDCCH的过程，包括：终端设备接收N个第一PDCCH。
在本申请实施例中，终端设备在对第K个第一PDCCH成功解码之后，终端设备就可以得到第一PDCCH的重复次数N，终端设备可以按照该第一PDCCH的重复次数N来接收第一PDCCH。
示例性的，若重复次数N为5，则终端设备接收5个第一PDCCH；若重复次数N为4，则终端设备接收4个第一PDCCH；若重复次数N为6，则终端设备接收6个第一PDCCH。
在本申请实施例中，终端设备确定第一PDCCH的重复次数N的过程，还可以为终端设备利用循环冗余校验CRC掩码对第一PDCCH进行多轮校验；若第一PDCCH校验成功，则终端设备统计多轮校验对应的校验次数；终端设备根据校验次数，确定重复次数N。
示例性的，终端设备利用循环冗余校验CRC掩码对第一PDCCH进行3轮校验时，第一PDCCH校验成功，则终端设备就确定重复次数N为3；终端设备利用循环冗余校验CRC掩码对第一PDCCH进行5轮校验时，第 一PDCCH校验成功，则终端设备就确定重复次数N为5。
在本申请实施例中，终端设备可以在一个搜索空间的多个传输位置处接收多个第一PDCCH。

在本申请实施例中，多个第一PDCCH对应一个聚合等级，多个第一PDCCH在聚合等级下对应一个序号。
在本申请实施例中，多个第一PDCCH对应一个聚合等级，即多个第一PDCCH的聚合等级相同，该多个第一PDCCH的聚合等级可以为2，该多个第一PDCCH的聚合等级可以为4；该多个第一PDCCH的聚合等级可以为8，该多个第一PDCCH的聚合等级可以为16，具体的可根据实际情况进行确定，本申请实施例对此不作限定。
在本申请实施例中，一个聚合等级对应一个CCE，若第一PDCCH的聚合等级为2，则该第一PDCCH中包括2个CCE；若第一PDCCH的聚合等级为4，则该第一PDCCH中包括4个CCE；若第一PDCCH的聚合等级为8，则该第一PDCCH中包括8个CCE；若第一PDCCH的聚合等级为16，则该第一PDCCH中包括16个CCE。
在本申请实施例中，多个第一PDCCH在聚合等级下对应一个序号，即多个第一PDCCH在聚合等级下的序号相同。
在本申请实施例中，多个传输位置中的相邻传输位置之间的传输间隔与多个第一PDCCH的数量相同。
在本申请实施例中，若多个第一PDCCH的重复次数为N，则多个传输位置中的相邻传输位置之间的传输间隔为N个时隙。示例性的，多个第一PDCCH的重复次数为5，则多个传输位置中的相邻传输位置之间的传输间隔为5个时隙；多个第一PDCCH的重复次数为3，则多个传输位置中的相邻传输位置之间的传输间隔为3个时隙。
在本申请实施例中，多个传输位置在以多个第一PDCCH的数量为倍数 的时隙中。
在本申请实施例中，终端设备也可以在多个搜索空间接收多个第一PDCCH，该多个搜索空间和多个第一PDCCH一一对应。
在本申请实施例中，终端设备可以在一个搜索空间的多个传输位置处接收多个第一PDCCH，终端设备也可以在多个搜索空间接收多个第一PDCCH，具体的终端设备接收多个第一PDCCH的方式，可根据实际情况进行确定，本申请实施例对此不作限定。
在本申请实施例中，多个搜索空间对应多个配置信息，多个搜索空间和多个配置信息一一对应；多个搜索空间被配置为聚合搜索空间；多个第一PDCCH对应一个聚合等级；多个第一PDCCH在聚合等级下对应一个序号。
在本申请实施例中，多个搜索空间对应多个配置信息，则该多个搜索空间为配置信息不同的多个搜索空间，终端设备通过对该配置信息不同的多个搜索空间进行聚合，从而得到聚合搜索空间。
在本申请实施例中，多个第一PDCCH的频域位置固定。
可以理解的是，多个第一PDCCH在多时隙重复传输时的频域位置固定，即在多时隙重复传输多个第一PDCCH的过程中，将根据时隙的移位而从下一个时隙的开始位置处重新传输第一PDCCH，使得多时隙重复传输时的第一PDCCH的频率响应趋近于固定频率，终端设备可以在该固定频率处对多个第一PDCCH进行信道估计和信道解码，提高了终端设备解码第一PDCCH时的准确率。
S200、根据多个第一PDCCH，传输第一PDCCH调度的第一数据。
在本申请实施例中，终端设备接收多个第一PDCCH之后，终端设备就根据该多个第一PDCCH传输第一PDCCH调度的第一数据。
在本申请实施例中，终端设备可以根据多个第一PDCCH携带的指示信息和重复次数N，确定第一数据的时域位置；终端设备在确定出第一数据 的时域位置的情况下，终端设备就可以在该时域位置处传输第一数据。
在本申请实施例中，指示信息包括多个第一PDCCH中的每一个PDCCH在时域上的偏移量。
示例性的，若多个第一PDCCH的重复次数N为5次，则指示信息中包括5个PDCCH在时域上的偏移量；若多个第一PDCCH的重复次数N为4次，则指示信息中包括4个PDCCH在时域上的偏移量；若多个第一PDCCH的重复次数N为3次，则指示信息中包括3个PDCCH在时域上的偏移量。
在本申请实施例中，终端设备确定多个第一PDCCH中首次接收的PDCCH的起始时域位置；终端设备确定出起始时域位置之后，终端设备就根据偏移量、重复次数N和起始时域位置，确定出第一数据的时域位置。
示例性的，如图2所示，图2中的左边位置处的物理下行控制信道1、物理下行控制信道2和物理下行控制信道3，表征第一PDCCH在3个时隙上重复传输了三次，物理下行控制信道3后面的是第一PDCCH调度的数据；图2中中间位置处有1个物理下行控制信道1，表征第二PDCCH在1个时隙上传输了一次，物理下行控制信道1后面的是第二PDCCH调度的数据；图2中右边位置处的物理下行控制信道1、物理下行控制信道2、物理下行控制信道3和物理下行控制信道4，表征第三PDCCH在4个时隙上重复传输了4次，物理下行控制信道4后面的是第三PDCCH调度的数据，其中，第三PDCCH第一次传输的时域位置为图2中右边位置处的物理下行控制信道1传输的时域位置，第三PDCCH重复次数为4次，第三PDCCH的偏移量为图2中最右边的物理下行控制信道4与图2中右边位置处的第三PDCCH调度的数据之间的间隔，根据第三PDCCH的偏移量、重复次数和起始时域位置(第三PDCCH第一次传输的时域位置)，可以确定第三PDCCH的调度的第一数据的时域位置。
在本申请实施例中，终端设备在确定出第一数据的时域位置之后，终 端设备就确定第一数据的时域位置所在的时隙，并在该时隙上传输该第一数据。
示例性的，第一数据的时域位置所在的时隙为第5个时隙，则终端在第5个时隙上传输该第一数据。
在本申请实施例中，终端设备从第一数据的时域位置所在的时隙开始，终端设备在多个时隙分别传输多个第一数据。
本申请实施例中，终端设备也可以通过多时隙重复接收网络传输的PUCCH、PUSCH、PDSCH等信道，来提高PUCCH、PUSCH、PDSCH等信道的覆盖，进而提高终端设备与网络进行通信时的可靠性，具体的终端设备多时隙重复接收网络传输的PUCCH、PUSCH、PDSCH的实施步骤，可根据终端设备多时隙重复接收网络传输的PDCCH的实施步骤进行确定。
需要说明的是，终端设备多时隙重复接收网络传输的PUCCH的方式，可以为PUCCH的多时隙重复传输的重复次数为N，若终端设备依次解码接收到的PUCCH，在终端设备解码到第K个PUCCH时成功解码，则终端设备继续接收剩余N-K个PUCCH，终端设备不对剩余的N-K个PUCCH进行解码；终端设备多时隙重复接收网络传输的PUSCH的方式，可以为PUSCH的多时隙重复传输的重复次数为N，若终端设备依次解码接收到的PUSCH，在终端设备解码到第K个PUSCH时成功解码，则终端设备继续接收剩余N-K个PUSCH，终端设备不对剩余的N-K个PUSCH进行解码；终端设备多时隙重复接收网络传输的PDSCH的方式，可以为PDSCH的多时隙重复传输的重复次数为N，若终端设备依次解码接收到的PDSCH，在终端设备解码到第K个PDSCH时成功解码，则终端设备继续接收剩余N-K个PDSCH，终端设备不对剩余的N-K个PDSCH进行解码。
可以理解的是，终端设备通过接收用于调度相同的第一数据的多个第一PDCCH，增加了第一PDCCH的传输数量，提高了第一PDCCH的覆盖。
