具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
图1示出的是本公开一个示意性实施例提供的通信系统的框图，如图1所示，该通信系统可以包括：接入网12和终端13。
接入网12中包括若干接入网设备120。接入网设备120可以是基站，基站是一种部署在接入网中用以为终端提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，在5G新空口(NR，New Radio)系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能描述，会变化。为方便描述，下文中将上述为终端提供无线通信功能的装置统称为接入网设备。
终端13可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备，移动台(Mobile Station，MS)，终端等等。为方便描述，上面提到的设备统称为终端。接入网设备120与终端13之间通过某种空口技术互相通信，例如Uu接口。
在NR系统中，为了降低终端实现的复杂度，NR R15仅支持顺序的HARQ调度。并且，针对上行传输，接入网设备不会向终端反馈确认(ACK)/否认(NACK)信息，而是直接通过调度信令中的新旧数据指示，指示终端是否进行数据重传，而且重传只能在同一个进程内完成。因此，在上行传输过程中终端就需要经历一个发送上行物理共享信道(Physical Uplink Shared Channel，PUSCH)，等待物理下行控制信道(Physical Downlink Control Channel，PDCCH)，再发送PUSCH重传的过程。
这种上行传输过程，增大了上行传输的时延。且上述过程中数据的重传合并，都在一个进程内进行，然而终端在覆盖受限的场景下(例如终端位于小区边缘)，若一个进程传输的都是错误的数据块，即使进行重传也难以保证合并后数据的准确性。
本公开实施例描述的通信系统以及业务场景是为了更加清楚地说明本公开实施例的技术方案，并不构成对本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着通信系统的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
图2是根据一示例性实施例示出的一种上行传输方法的流程图。参见图2，该方法包括以下步骤：
在步骤101中，接入网设备接收终端通过多个HARQ进程发送的相同上行传输。
这里，HARQ进程是指接入网设备通过调度进行一次上行传输重传的过程。这里多个HARQ进程是并发的。本公开实施例通过接入网设备同时调度产生多个HARQ进程传输相同的数据包。
在步骤102中，接入网设备对所述多个HARQ进程发送的上行传输进行合并处理。
在本公开的所有实施例中，上行传输(Uplink Transmission)可以为以下的 任一种：数据、信令、数据和信令混合传输；即上行传输可以为任何传输。
接入网设备将多个HARQ进程发送的上行传输进行跨进程软合并解码，由于单独的一个上行传输可以存在缺失或错误的问题，通过多个上行传输的软合并解码，提高信息正确解码的概率。
在本公开实施例中，通过接入网设备同时调度产生多个HARQ进程传输相同的上行传输，接入网设备将多个HARQ进程发送的上行传输进行合并处理，提高信息正确解码的概率。这样一方面可以降低传输时延，另一方面可以提高上行传输质量，从而增强上行业务信道覆盖。
可选地，所述对所述多个HARQ进程发送的上行传输进行合并处理，包括：
确定属于同一个HARQ进程包的HARQ进程；
将所述属于同一个HARQ进程包的HARQ进程发送的上行传输进行合并处理。
在本公开实施例中，将终端支持的HARQ进程分为HARQ进程包(bundle)，在同一个HARQ进程包内的HARQ进程可以调度同一个上行传输。因此，接入网设备只需要确定HARQ进程属于同一个HARQ进程包，即可将这些HARQ进程传输的上行传输进行合并。
在本公开实施例中，HARQ进程包的配置可以有多种方式，例如接入网设备和终端各自通过协议确定。也可以为由接入网设备确定后通知给终端，例如由接入网设备通过协议确定后，通知给终端。还可以由接入网设备基于网络状况进行配置，然后通知给终端。
例如，接入网设备可以基于终端性能，确定一个HARQ进程包中的HARQ进程数量，然后将相应数量的HARQ进程划分到一个HARQ进程包，然后指示给终端。
比如，终端性能越差，一个HARQ进程包包括的HARQ进程的数量越多，这样一方面保证传输质量，另一方面降低传输时延。相反，终端性能越好，一个HARQ进程包包括的HARQ进程的数量越少。
可选地，该方法还可以包括：
向所述终端发送用于指示属于同一个HARQ进程包的HARQ进程的控制指令。
一个HARQ进程包可以包括1个或多个HARQ进程，一个HARQ进程包中HARQ进程的数量默认可以为1；当应用本公开实施例提供的方案时，才将 一个HARQ进程包中HARQ进程的数量配置为2或者更多。
在本公开实施例中，接入网设备指示终端属于同一个HARQ进程包的HARQ进程的方式也有多种：
示例性地，所述控制指令包括：HARQ进程包的大小(bundle size)，所述HARQ进程包的大小用于指示所述终端按照所述HARQ进程包的大小将多个HARQ进程划分为至少一个HARQ进程包。
在该实现方式中，控制指令中仅指示进程包的大小，例如2、4、8、16，或者为1、2、3、4、5等，默认值为1。终端接收到该控制指令后，可以基于该数值，从设定的HARQ进程开始，将相应数量的HARQ进程划分为一个HARQ进程包。例如，从HARQ进程0开始，将2个HARQ进程，HARQ进程0和HARQ进程1划分到一个HARQ进程包中。
示例性地，所述控制指令包括：属于同一个HARQ进程包的HARQ进程号。
例如，控制指令中直接指示HARQ进程0和HARQ进程1属于同一个HARQ进程包。
示例性地，所述控制指令包括：指示HARQ进程传输的上行传输，传输相同上行传输的HARQ进程属于同一个HARQ进程包。
例如，接入网设备直接指示终端在每个HARQ进程上传输什么上行传输，传输相同上行传输的HARQ进程则属于同一个HARQ进程包，这种通知方式实际隐含了属于同一个HARQ进程包的HARQ进程的信息。
可选地，向所述终端发送用于指示所述属于同一个HARQ进程包的HARQ进程的控制指令，包括：
向所述终端发送携带所述控制指令的PDCCH。
可选地，向所述终端发送携带所述控制指令的PDCCH，包括：
在多个HARQ进程分别向所述终端发送PDCCH，在所述多个HARQ进程上发送的PDCCH携带的所述控制指令指示所述终端传输相同的上行传输。
比如，在PDCCH 0调度信令中，指示HARQ进程0传输上行传输A；在PDCCH 1调度信令中，指示HARQ进程1也传输上行传输A。此时HARQ进程0和HARQ进程1属于同一个HARQ进程包。
可选地，所述多个HARQ进程上发送的PDCCH中新旧数据指示相同，所述新旧数据指示用于指示传输的上行传输为新的上行传输或重传上行传输。
例如，同一个HARQ进程包中的多个HARQ进程在重传上行传输A时，新 旧数据指示(NDI)均标识为1，用于表示上行传输重传。而当多个HARQ进程在传输新的上行传输时，新旧数据指示均标识为0。当然，也可以采用相反的指示方式或者其他指示方式，只要多个HARQ进程的指示方式一致即可。
值得说明的是，前述步骤101～步骤102与上述可选步骤可以任意组合。
图3是根据一示例性实施例示出的一种上行传输方法的流程图。参见图3，该方法包括以下步骤：
在步骤201中，终端确定待传输的上行传输。
在步骤202中，终端通过多个HARQ进程向接入网设备发送所述待传输的上行传输，其中所述多个HARQ进程传输相同的所述上行传输。
这里，HARQ进程是指接入网设备通过调度进行一次上行传输重传的过程。这里多个HARQ进程是并发的。本公开实施例通过接入网设备同时调度产生多个HARQ进程传输相同的上行传输。
在本公开实施例中，通过接入网设备同时调度产生多个HARQ进程传输相同的上行传输，接入网设备将多个HARQ进程发送的上行传输进行合并处理，提高信息正确解码的概率。这样一方面可以降低传输时延，另一方面可以提高上行传输质量，从而增强上行业务信道覆盖。
可选地，通过所述多个HARQ进程向接入网设备发送所述待传输的上行传输，包括：
确定属于同一个HARQ进程包的HARQ进程；

可选地，所述控制指令包括：HARQ进程包的大小，所述HARQ进程包的大小用于指示终端按照所述HARQ进程包的大小将多个HARQ进程划分为至少一个HARQ进程包；
或者，所述控制指令包括：属于同一个HARQ进程包的HARQ进程号；
或者，所述控制指令包括：指示HARQ进程传输的上行传输，传输相同的上行传输的HARQ进程属于同一个HARQ进程包。
可选地，接收所述接入网设备发送的用于指示所述属于同一个HARQ进程包的HARQ进程的控制指令，包括：
接收所述接入网设备发送的携带所述控制指令的PDCCH。
可选地，接收所述接入网设备发送的携带所述控制指令的PDCCH，包括：
在多个HARQ进程分别接收所述接入网设备发送的PDCCH，在所述多个HARQ进程上发送的PDCCH携带的所述控制指令指示终端传输相同的上行传输。
可选地，所述多个HARQ进程上发送的PDCCH中新旧数据指示相同，所述新旧数据指示用于指示传输的上行传输为新的上行传输或重传上行传输。
值得说明的是，前述步骤201～步骤202与上述可选步骤可以任意组合。
图4是根据一示例性实施例示出的一种上行传输方法的流程图。参见图4，该方法包括以下步骤：
在步骤301中，接入网设备确定用于指示属于同一个HARQ进程包的HARQ进程的第一控制指令。
一个HARQ进程包可以包括1个或多个HARQ进程，一个HARQ进程包中HARQ进程的数量默认可以为1，只有采用本公开实施例提供的方案时，才将一个HARQ进程包中HARQ进程的数量配置为2或者更多。
在本公开实施例中，接入网设备指示终端属于同一个HARQ进程包的HARQ进程的方式也有多种：
示例性地，所述第一控制指令包括：HARQ进程包的大小(bundle size)，所述HARQ进程包的大小用于指示所述终端按照所述HARQ进程包的大小将多个HARQ进程划分为至少一个HARQ进程包。
在该实现方式中，第一控制指令中仅指示进程包的大小，例如2、4、8、16，或者为1、2、3、4、5等，默认值为1。终端接收到该第一控制指令后，可以基于该数值，从设定的HARQ进程开始，将相应数量的HARQ进程划分为一个HARQ进程包。例如，从HARQ进程0开始，将2个HARQ进程，HARQ进程0和HARQ进程1划分到一个HARQ进程包中。
示例性地，所述第一控制指令包括：属于同一个HARQ进程包的HARQ进程号。
例如，第一控制指令中直接指示HARQ进程0和HARQ进程1属于同一个 HARQ进程包。
需要说明的是，本公开提供的采用多个HARQ进程进行相同上行传输的方法，可以通过在接入网设备上进行配置，以激活该功能或者去激活该功能，只有在激活状态下，才会执行步骤301～步骤305。
在步骤302中，接入网设备发送第一控制指令。终端接收第一控制指令。
例如，接入网设备向所述终端发送携带所述第一控制指令的PDCCH。
可选地，所述多个HARQ进程上发送的PDCCH中新旧数据指示相同，所述新旧数据指示用于指示传输的上行传输为新的上行传输或重传上行传输。
例如，同一个HARQ进程包中的多个HARQ进程在重传上行传输A时，新旧数据指示(NDI)均标识为1，用于表示上行传输重传。而当多个HARQ进程在传输新的上行传输时，新旧数据指示均标识为0。当然，也可以采用相反的指示方式或者其他指示方式，只要多个HARQ进程的指示方式一致即可。
在步骤303中，终端确定待传输的上行传输。
这里，待传输的上行传输也即需要采用HARQ进行传输的上行传输。
在步骤304中，终端通过多个HARQ进程向接入网设备发送所述待传输的上行传输。接入网设备接收终端通过多个HARQ进程发送的相同上行传输。
这里，HARQ进程是指接入网设备通过调度进行一次上行传输重传的过程。这里多个HARQ进程是并发的。本公开实施例通过接入网设备同时调度产生多个HARQ进程传输相同的上行传输。
在步骤305中，接入网设备对所述多个HARQ进程发送的上行传输进行合并处理。
接入网设备将多个HARQ进程发送的上行传输进行跨进程软合并解码，由于单独的一个上行传输可以存在缺失或错误的问题，通过多个上行传输的软合并解码，提高信息正确解码的概率。
图5是根据一示例性实施例示出的一种上行传输方法的流程图。参见图5，该方法包括以下步骤：
在步骤401中，接入网设备确定第二控制指令，所述第二控制指令包括：指示HARQ进程传输的上行传输，传输相同上行传输的HARQ进程属于同一个HARQ进程包。
例如，接入网设备直接指示终端在每个HARQ进程上传输什么上行传输， 传输相同上行传输的HARQ进程则属于同一个HARQ进程包，这种通知方式实际隐含了属于同一个HARQ进程包的HARQ进程的信息。
需要说明的是，本公开提供的采用多个HARQ进程进行相同上行传输的方法，可以通过在接入网设备上进行配置，以激活该功能或者去激活该功能，只有在激活状态下，才会执行步骤401～步骤405。

比如，在PDCCH 0调度信令中，指示HARQ进程0传输上行传输A；在PDCCH 1调度信令中，指示HARQ进程1也传输上行传输A。此时HARQ进程0和HARQ进程1属于同一个HARQ进程包。
可选地，所述多个HARQ进程上发送的PDCCH中新旧数据指示相同，所述新旧数据指示用于指示传输的上行传输为新的上行传输或重传上行传输。
例如，同一个HARQ进程包中的多个HARQ进程在重传上行传输A时，新旧数据指示(NDI)均标识为1，用于表示上行传输重传。而当多个HARQ进程在传输新的上行传输时，新旧数据指示均标识为0。当然，也可以采用相反的指示方式或者其他指示方式，只要多个HARQ进程的指示方式一致即可。
在步骤403中，终端确定待传输的上行传输。
这里，待传输的上行传输即第二控制指令中指示的上行传输。
