背景技术
为了更好的满足日益增长的业务类型需求，新的接入技术例如5G(New Radio，NR)技术中要求支持除了长期演进(Long Term Evolution，LTE)中已经支持的增强移动宽带(Enhanced Mobile Broadband，eMBB)和广播业务外，又额外引入了高可靠低延迟通信(Ultra-Reliable and Low Latency Communications，URLLC)和大规模机器通信(massive Machine Type Communication，mMTC)两种新的业务类型。其中，每种业务类型的业务特点，可靠性要求或者时延要求都具有明显的差异性。
URLLC业务期望的时延非常短，最低仅有1ms。可见，URLLC业务由于时延紧急，调度花费的时间短，并且在有数据到达时需要即刻调度分配资源，基本不能有等待。另一方面，URLLC业务对可靠性的要求也很高，一般要求能够达到99.999％的超高可靠性。
LTE中，混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)实体存在于介质控制访问(Media Access Control，MAC)层，发送数据时，MAC层通过将逻辑信道和控制单元复用以后，形成对应的传输块(Transport Block，TB)，然后将对应的TB块交给HARQ实体，HARQ实体将HARQ信息和TB分配给对应的HARQ进程，每个HARQ实体包含多个并行的HARQ进程，每个HARQ进程都有一个HARQ进程号。
并且每个HARQ进程都有一个对应的HARQ缓存，接收到的错误数据包会保存在一个HARQ缓存中，并与后续接收到的重传数据包进行合并，从而得到一个比单独解码更可靠的数据包(“软合并”的过程)。然后对合并后的数据包进行解码，如果还是失败，则重复“请求重传，再进行软合并”。
在载波聚合的情况下，每个载波上都存在一个HARQ实体。一个HARQ实体管理本载波的HARQ进程和HARQ缓存，在本载波上接收到的上行或下行数据的缓存需要放到本载波对应的HARQ进程的缓存中。现有技术将HARQ进程限制在每个载波的内部，当在不同载波同时传输数据时，无法实现载波间的软合并译码，降低译码成功率。
