为了支持低时延高可靠业务传输需求，在5G新空口(New Radio，NR)系统中引入了重复传输机制。其中，重复传输机制可以是指通过多个路径传输相同的分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)协议数据单元(Protocol Data Unit，PDU)，这样通过多路径传输增益提升传输可靠性，并降低传输时延。具体是将PDCP层的一个无线承载(Radio Bearer，RB)(RB也可以称作业务承载)在无线链路控制(Radio Link Control，RLC)层通过多个逻辑信道分别进行传输，其中，一个逻辑信道对应一个RLC实体。然而，目前的重复传输机制中两个逻辑信道的数据需要在不同的小区进行传输，这样导致小区内资源利用率比较低。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
参见图1，图1是本公开实施例可应用的网络结构示意图，如图1所示，包括终端11和网络侧设备12，其中，终端11可以是用户终端(User Equipment，UE)或者其他终端设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，简称PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备，需要说明的是，在本公开实施例中并不限定终端的具体类型。网络侧设备12可以是基站，例如：宏站、LTE eNB、5G NR NB等；网络侧设备也可以是小站，如低功率节点(LPN：low power node)、pico、femto等小站，或者网络侧设备可以接入点(AP，access point)；基站也可以是中央单元(CU，central unit)与其管理是和控制的多个传输接收点(TRP，Transmission Reception Point)共同组成的网络节点。需要说明的是，在本公开实施例中并不限定网络侧设备的具体类型。
请参见图2，图2是本公开实施例提供的一种重复传输方法的流程图，如图2所示，包括以下步骤：
步骤201、终端接收网络侧发送的配置信令，所述配置信令包括重复传输配置，所述重复传输配置包括：一个RB映射到多个RLC实体上，且不同RLC实体配置不同的逻辑信道，以及不同的逻辑信道对应不同的BWP；
步骤202、所述终端根据所述重复传输配置进行重复传输操作。
其中，上述配置信令可以为RRC信令，当然对此不作限定，例如：还可以网络侧设备能够向终端发送的其他信令。
另外，上述RB可以是PDCP层重复传输的RB。上述重复传输配置可以如图3所示，将一个RB映射到不同的RLC实体，并为不同的RLC实体配置不同的逻辑信道，每个逻辑信道配置有对应的BWP，例如：如图3所示，每个逻辑信道配置一个BWP组(BWPG)，每个BWP组内包括两个BWP。
需要说明的是，图3所示的重复传输配置仅是一个示意，例如：可以为不同的逻辑信道配置不同数量的BWP，或者为部分逻辑信道配置相同数量的BWP，而另一些逻辑信道配置不同数量的BWP。
当终端接收到上述重复传输配置后，就可以根据该重复传输配置进行相应的重复传输。
需要说明的是，上述重复传输配置为上述RB配置的多个BWP可以是将小区的大带宽划分为多个BWP中的部分BWP。例如：在NR系统中，一个小区的网络侧带宽很大，如可以高达400MHz，因此，在NR系统中引入BWP的概念，将小区的大带宽划分为多个BWP。
通过上述步骤可以实现在将RB对应的多个逻辑信道数据在不同的BWP上传输，从而提高小区内资源利用率。另外，对于终端只有一个大带宽小区可用的情况，采用上述方法可以进行重复传输，从而获得重复传输对降低时延和提高可靠性的增益，进而满足高可靠低时延通信(Ultra-Reliable and Low Latency Communications，URLLC)业务需求。
作为一种可选的实施方式，所述重复传输配置包括：
LCID与BWP索引的对应关系，其中，该对应关系中一个LCID对应一个或者多个BWP索引；或者
LCID与BWP组标识的对应关系，其中，该对应关系中每个BWP组包括一个或者多个BWP。
其中，上述重复传输配置包括多个LCID与BWP索引(BWP index)的对应关系，这样通过该对应关系可以为不同的逻辑信道配置不同的BWP。该实施方式中，可以实现网络侧设备在配置信令中指示不同逻辑信道对应的一个或多个BWP。另外，上述重复传输配置中可以包括上行逻辑信道的配置，和/或下行逻辑信道的配置。
例如：网络侧设备在对PDCP重复传输的RRC配置信令中，配置对应一个RB的两个或更多RLC实体及每个RLC实体对应的逻辑信道号，并配置每个重复传输逻辑信道对应的一个或多个BWP index。
终端接收RRC配置信令，确定RB的PDCP重复传输配置，该配置包括对应的RLC实体和逻辑信道号，并通过每个重复传输逻辑信道号对应的BWP index确定该逻辑信道数据可以进行传输的BWP。
另外，上述实施方式中，通过上述LCID与BWP组标识(BWPG ID)的对应关系，可以实现在上述重复传输配置中指示不同逻辑信道对应的BWP 组标识，由于重复传输配置中只需要携带BWP组标识，从而可以降低传输开销。另外，在该实施方式中，可以是网络侧设备先将BWP分组，分配BWP组标识，再将LCID与BWP组标识(BWPG ID)对应。
例如：网络侧设备在对终端进行BWP配置的RRC信令中，将BWP进行分组，将不同BWP分配到不同的BWP组，每个BWP组包含一个或多个BWP。之后，在对PDCP重复传输的RRC配置信令中，配置对应一个RB的两个或更多RLC实体及每个RLC实体对应的逻辑信道号，配置每个重复传输逻辑信道对应的BWP组ID。
终端接收BWP配置的RRC信令，确定BWP和BWP组的映射关系；以及接收PDCP重复传输的RRC配置信令，确定RB的PDCP重复传输配置，包括对应的RLC实体和逻辑信道号，对应的BWP组ID，并通过BWP组ID和BWP的映射关系，确定每个重复传输逻辑信道号对应的BWP。
作为一种可选的实施方式，所述多个RLC实体中包括一个主RLC实体，在重复传输不激活的情况下，所述RB通过所述主RLC实体进行传输。
该实施方式中，可以实现在重复传输配置下，一个RB可以映射到两个或大于两个RLC实体，其中一个RLC实体定义为主RLC实体，这样在重复传输不激活的时候，该RB的实体只通过主RLC实体，以及对应的逻辑信道传输，而不需要再次进行配置，从而可以降低实现的复杂度。
作为一种可选的实施方式，所述重复传输配置通过如下方式激活或者去激活：
RRC信令激活或者RRC信令去激活，其中，所述RRC信令为所述配置信令。
需要说明的是，上述RRC信令激活或者RRC信令去激活可以理解为，通过激活和去激活是采用不同的RRC信令来实现的，但激活的RRC信令，以及去激活的RRC信令均可以是上述配置信令，也就是说，上述配置信令除了用于上述重复传输配置之外，还可以用于激活或者去激活上述重复传输配置，这样在激活或者去激活时，不需要传输其他信令，从而降低传输开销。
在一种实现方式中，上述所述RRC信令指示所述重复传输配置中的激活BWP，其中，若所述RB对应的逻辑信道中存在多个激活逻辑信道，则表示 所述RB重复传输激活，所述激活逻辑信道对应的BWP中存在激活BWP；若所述RB中对应的逻辑信道中存在未激活逻辑信道，则所述未激活逻辑信道不能进行传输。
该实现方式中，可以通过上述RRC信令指示重复传输配置中的激活BWP，例如：上述重复传输配置中包括RLC实体与BWP组的对应关系时，则该RRC信令可以指示BWP组中的激活BWP。如果网络侧设备指示了BWP组中的激活BWP，则表示该BWP组对应的逻辑信道可以在激活的BWP上传输，也表示该逻辑信道对应的重复传输激活。
另外，上述未激活逻辑信道可以是对应的至少一个BWP(或者BWP组)没有激活BWP配置的逻辑信道，例如：上述RRC信令指示的上述重复传输配置中的激活BWP中没有上述未激活逻辑信道对应至少一个BWP(或者BWP组)中的BWP。这样可以实现如果某逻辑信道对应的BWP组没有激活的BWP配置，则表示该逻辑信道不能进行传输，即PDCP层不会将复制包传递给该RLC实体传输。通过上述RRC信令可以实现激活RB对应的多个逻辑信道中的部分逻辑信道，以及不激活或者去激活另一部分逻辑信道，当然，也可以是激活RB对应的所有逻辑信道，从而可以提高重复传输的灵活性。
例如：网络侧设备可以在配置RLC实体与BWP组的对应关系的RRC信令中，同时配置激活BWP。
终端接收网络侧设备PDCP重复传输配置的RRC信令，确定重复传输逻辑信道与BWP组的对应关系，如果一个逻辑信道对应的BWP组中有激活BWP，则表示激活该重复传输逻辑信道，即可以在该BWP组中传输重复传输的数据；如果一个逻辑信道对应的BWP组中没有激活BWP配置，则表示不激活该重复传输逻辑信道，PDCP层不会将重复传输数据递交给该逻辑信道。
在另一种实现方式中，所述RRC信令指示所述RB是否激活重复传输，如果激活，则该RB对应的所有逻辑信道都要进行传输，如果不激活，则该RB的数据只在主逻辑信道上传输。
其中，上述主逻辑信道可以是指上述RB的主RLC实体对应的主逻辑信道，或者可以理解为上述主逻辑信道为激活状态为激活的逻辑信道。
该实现方式中，通过上述RRC信令激活或者去激活上述RB的所有逻辑信道的重复传输。可选的，可以是用1bit指示该RB的重复传输初始状态为激活或不激活，如果指示为不激活，则只有主RLC实体有数据传输，其他RLC实体(及其逻辑信道)对应的BWP组即使有激活BWP，也不传输重复数据包。由于直接通过上述RRC信令激活或者去激活上述RB的重复传输，从而可以节约RRC信令的开销，以及降低实现的复杂度。
例如：网络侧设备可以在PDCP重复传输配置命令中，同时指示该PDCP重复传输是否激活。
终端接收PDCP重复传输配置命令，如果RRC信令指示PDCP重复传输激活，则该RB对应的所有配置的重复传输逻辑信道都激活，即可以在对应的BWP组中进行重复传输；如果RRC信令指示PDCP重复传输不激活，则该RB的传输状态是只能在主RLC实体及其对应的逻辑信道进行传输。后续的激活去激活信令可以改变这种初始状态。
在另一种实现方式中，所述RRC信令分别指示所述RB对应的逻辑信道是否激活传输，指示激活的逻辑信道能够进行传输，指示非激活的逻辑信道不能进行传输。
其中，上述指示激活的逻辑信道能够进行传输可以理解为，终端可以在该逻辑信道进行传输。
该实现方式中，通过上述RRC信令以逻辑信道为单位进行激活或者去激活，也就是说，上述RRC信令可以激活上述RB对应的多个逻辑信道中的部分或者全部逻辑信道，从而在指示激活的逻辑信道进行传输。以逻辑信道与BWP组的对应关系进行举例，该实现方式可以实现针对重复传输逻辑信道，即BWP组激活重复传输，网络侧设备可以在配置逻辑信道与BWP组的对应关系时，同时指示该组传输是否激活，如果配置为不激活，即使该BWP组有激活BWP，也不进行该RLC实体的数据的传输，即PDCP层不会将复制包传递给该RLC实体。该实现方式中，可以提高重复传输的灵活性。
例如：网络侧设备可以在PDCP重复传输配置命令中，在配置逻辑信道与BWP组的对应关系时，同时指示该逻辑信道是否激活传输。
终端接收PDCP重复传输配置命令，如果配置为不激活，即使该BWP 组有激活BWP，也不进行该逻辑信道的数据的传输，即PDCP层不会将复制包传递给该RLC实体。
作为一种可选的实施方式，所述重复传输配置通过如下方式激活或者去激活：
MAC信令激活或者MAC信令去激活。
需要说明的是，上述MAC信令激活或者MAC信令去激活可以理解为，通过激活和去激活是采用不同的MAC信令来实现的。可选的，上述MAC信令可以为MAC控制单元(Control Element，CE)，即MAC CE。
一种实现方式中，所述MAC信令激活或者去激活特定RB的重复传输。
其中，上述特定的RB可以是上述重复传输配置中的RB。
该实现方式中，可以实现通过MAC信令激活或者去激活特定RB的重复传输，其中，激活表示激活所有重复传输路径，即RB对应的所有RLC实体及逻辑信道的重复传输；去激活表示只能在主RLC实体上传输，即完全没有重复数据包的传输。
在另一种实现方式中，上述MAC信令激活或者去激活特定重复传输路径，其中，所述特定重复传输路径为所述重复传输配置中一个或者多个重复传输路径，该重复传输路径包括逻辑信道和/或BWP。
该实现方式中，可以实现MAC信令激活或去激活特定重复传输路径，如RLC实体和逻辑信道的重复传输，和/或BWP的重复传输，从而提高重复传输的灵活性。
例如：网络侧设备发送MAC CE，该MAC CE指示激活或去激活特定RB的重复传输(MAC CE格式1)；或该MAC CE指示激活或去激活特定重复传输路径(MAC CE格式2)，即特定逻辑信道的重复传输。
终端接收网络侧设备发送的激活或者去激活的MAC CE，如果采用MAC CE格式1，激活表示激活所有重复传输路径，即激活该RB对应的所有RLC实体及逻辑信道的重复传输；去激活表示该RB只能在主RLC实体上传输，即完全没有重复数据包的传输。如果采用MAC CE格式2，终端根据MAC CE指示确定激活或去激活特定重复传输路径，PDCP层不将重复传输包递交给该去激活的逻辑信道。
作为一种可选的实施方式，所述重复传输配置通过如下方式激活或者去激活：
物理层信令激活或者物理层信令去激活。
需要说明的是，上述物理层信令激活或者物理层信令去激活可以理解为，通过激活和去激活是采用不同的物理层信令来实现的。可选的，上述物理层信令为物理下行控制信道(Physical Downlink Control Channel，PDCCH)携带的控制消息。
一种实现方式中，所述物理层信令激活或者去激活所述终端的重复传输。
其中，上述终端的重复传输可以是指终端的所有重复传输，该实现方式中，可以实现激活或者去激活终端的所有重复传输，即终端的所有RB同时激活或去激活。
需要说明的是，实施方式中，可以是临时挂起该终端的重复传输，而不改变RRC配置和/或MAC层指定的激活状态，以提高重复传输的灵活性。例如：由于信道环境恶化，部分BWP组不可用所致时，可以去激活该终端的重复传输。
另一种实现方式中，所述物理层信令激活或者去激活特定BWP或者特定BWP组承载的重复传输。
该实现方式中，可以实现通过物理层信令激活或者去激活部分BWP或部分BWP组可以承载的重复传输，这样针对该BWP组对应的所有重复传输RB的逻辑信道有效。
例如：网络侧设备发送PDCCH，该PDCCH携带控制消息指示进行重复传输激活或去激活。其中，该控制消息可以是下行控制信息(Downlink Control Information，DCI)，DCI格式1，激活或去激活该终端的重复传输；或DCI格式2：指示激活或去激活部分BWP或BWP组可以承载的重复传输。
终端接收网络侧设备发送的PDCCH命令。如果采用DCI格式1，指示激活时，终端确定激活针对该终端配置且高层信令已指示激活的所有RB的重复传输，指示去激活时，终端去激活所有配置了PDCP重复传输的RB的重复传输；如果采用格式2，针对PDCCH指示激活或去激活指定BWP或BWP组对应的所有重复传输RB的重复传输逻辑信道。
需要说明的是，上述介绍的重复传输的多种激活或者去激活的实施方式，步骤202在进行重复传输时，需要结合终端、逻辑信道、BWP等的激活状态进行传输。
作为一种可选的实施方式，所述终端根据所述重复传输配置进行重复传输操作，包括：
若所述重复传输配置中特定BWP组有多个激活BWP时，在所述特定BWP组对应的逻辑信道的数据在所述多个激活BWP中的一个或者多个BWP上传输；或者
若所述重复传输配置中一BWP组内发生激活BWP变更，该BWP组对应的逻辑信道的数据在该BWP组中新激活的BWP上进行HARQ重传；或者
若所述重复传输配置中的重复传输去激活，但存在未传输成功的RLC数据，则在所述终端的任意一个或者多个激活BWP上传输该RLC数据。
该实现方式中，可以实现若逻辑信道对应的BWP组有多个激活BWP时，可以选择部分或者全部激活BWP进行传输，从而提高传输的灵活性，以及传输性能。例如：当一个BWP组有多个BWP激活时，根据调度或资源预配置，该逻辑信道的数据可以在一个或多个BWP上传输。
另外，还可以实现若某一逻辑信道对应的BWP中发生激活BWP变更，则在新激活的BWP上进行HARQ重传，从而提高传输性能。例如：如果BWP组内发生激活BWP变更，该逻辑信道的数据可以在该新激活的BWP上进行HARQ重传。
另外，还可以实现若去激活，但存在未传输成功的RLC数据，则可以在任意一个或者多个激活BWP上传输该RLC数据，此时不再受BWP组限制，从而提高传输性能。例如：如果重复传输去激活，重复传输的RLC实体和逻辑信道不会有新数据，但未传输成功的RLC数据可以在任意一个激活BWP上传输(不再受BWP组限制)。
本公开实施例中，所述终端接收网络侧发送的配置信令，所述配置信令包括重复传输配置，所述重复传输配置包括：RB映射到多个RLC实体上，且不同RLC实体配置不同的逻辑信道，以及不同的逻辑信道对应不同的部分带宽BWP；所述终端根据所述重复传输配置进行重复传输操作。这样可以实 现在将RB对应的多个逻辑信道数据在不同的BWP上传输，从而提高小区内资源利用率。

可选的，所述重复传输配置包括：

可选的，所述RRC信令指示所述重复传输配置中的激活BWP，其中，若所述RB对应的逻辑信道中存在多个激活逻辑信道，则表示所述RB重复传输激活，所述激活逻辑信道对应的BWP中存在激活BWP；若所述RB中对应的逻辑信道中存在未激活逻辑信道，则所述未激活逻辑信道不能进行传输；或者
所述RRC信令指示所述RB是否激活重复传输，如果激活，则该RB对应的所有逻辑信道都要进行传输，如果不激活，则该RB的数据只在主逻辑信道上传输；或者
