Description
本申请涉及的无线通信系统中的传输方法和装置,尤其涉及采用循环冗余校验和信道编码技术的无线通信系统中的传输方案和装置。
下一代移动通信系统会支持多种多样的业务,从高吞吐量要求的eMBB业务到低延迟、高可靠性要求的URLLC(Ultra-Reliable Low Latency Communication,超可靠低时延通信)业务。不同种类业务,比如eMBB业务和mMTC(massive Machine-Type Communications,大规模机器类型通信)业务,需要的传输块大小会有很大差异,从几十比特到几万比特都有可能。如何在同一个系统中支持大小差别迥异的传输块,并且同时保证每一种大小的传输块都能获得理想的传输效率是一个需要解决的问题。
