Description

数据传输方法及装置 技术领域
本发明涉及通信技术领域，尤其涉及一种数据传输方法及装置。
背景技术
由于不同业务类型对于无线通信技术有不同的服务质量要求，如增强移动宽带(eMBB，enhanced Mobile Broad Band)业务类型主要的要求侧重于大带宽、高速率等方面，高可靠低时延通信(URLLC，Ultra Reliable Low Latency Communication)业务类型主要的要求侧重于较高的可靠性以及低的时延方面，海量机器类通信(mMTC，massive machine type of communication)业务类型主要的要求侧重于大的连接数方面，因此，新一代的无线通信系统需要通过灵活和可配置的设计来支持多种业务类型的传输。
相关技术中，在物理下行共享信道(PDSCH，Physical Downlink Shared CHannel)/物理上行共享信道(PUSCH，Physical Uplink Shared CHannel)的映射类型B(mapping typeB)中，允许从一个时隙(slot)的任意一个符号开始传输，且对于PDSCH传输，允许传输持续时间可以为2个符号、4个符号或7个符号，对于PUSCH允许的传输时间可以为1-14个符号任意的取值；同时，相关技术规定了一个传输突发不能跨slot边缘。但是，若当前slot内可以用的物理资源少于实际需要的物理资源，则会导致速率匹配输出的码率增高，从而使传输质量变差，而这对于诸如URLLC业务及eURLLC业务等对传输可靠度要求较高的业务来说，难以满足业务高可靠性服务质量要求，严重影响业务质量。
