Description

本申请涉及无线通信系统中的传输方案，特别是涉及支持混合自动重传请求的过程中进行数据传输的方法和装置。
背景技术
未来无线通信系统的应用场景越来越多元化，不同的应用场景对系统提出了不同的性能要求。为了满足多种应用场景的不同的性能需求，在3GPP(3rd Generation Partner Project，第三代合作伙伴项目)RAN(Radio Access Network，无线接入网)#72次全会上决定对新空口技术(NR，New Radio)进行研究。在3GPP RAN#75次全会上通过了5G新空口技术(NR)的工作项目(WI，Working Item)的立项，开始对5G新空口技术进行标准化。
为了能够灵活适应多种不同的应用场景，未来的无线通信系统，特别是5G NR将可以支持更加灵活的混合自动重传请求(HARQ，Hybrid Automatic Repeat request)和对应的数据重传设计，比如支持基于CB(Code Block，编码块)或CBG(Code Block Group，编码块组)的HARQ重传。而在现有的LTE系统中，只支持基于TB(Transport Block，传输块)的HARQ重传，相应的在速率匹配(Rate Matching)过程中的缓存资源(Soft buffer bits)的分配也是按照整个TB块中包含的CB进行分配的。
