Description

一种被用于无线通信的用户设备、基站中的方法和装置 技术领域
本申请涉及无线通信系统中的方法和装置，尤其是涉及支持多天线传输的无线通信系统中的方法和装置。
背景技术
和传统的3GPP(3rd Generation Partner Project，第三代合作伙伴项目)LTE(Long-term Evolution，长期演进)系统相比，5G系统支持更加多样的应用场景，比如eMBB(enhanced Mobile BroadBand，增强移动宽带)，URLLC(Ultra-Reliable and Low Latency Communications，超高可靠性和低延迟通信)和mMTC(massive Machine-Type Communications，大规模机器类型通信)。和其他应用场景相比，URLLC对传输可靠性和延时都有更高的要求。3GPP R(Release，版本)15支持采用不同的MCS(Modulation and Coding Scheme，调制编码方式)表格和重复传输来提高传输可靠性。在R16中，URLLC场景下的性能会被进一步增强。
发明内容
发明人通过研究发现，基于多天线技术的空域发送分集(spatial diversity)是进一步提高URLLC场景下传输可靠性的潜在解决方案。对一个TB(Transport Block，传输块)进行多次重复传输，并用不同的预编码矩阵/向量来发送不同的重复传输，能利用空域分集增益提高传输可靠性。目前3GPP支持基于码本和非码本的上行传输。对基于码本的上行传输，调度信令指示所使用的预编码矩阵。对于一个TB多次重复传输的情况，如何为不同的重复传输指示不同的预编码矩阵，并尽可能降低带来的信令开销和对标准的影响，是需要解决的问题。
针对上述问题，本申请公开了一种解决方案。在不冲突的情况下，本申请的用户设备中的实施例和实施例中的特征可以应用到基站中，反之亦然。在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。
