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无线信号的传输方法和装置，尤其是支持蜂窝网的无线通信系统中的无线信号的传输方法和装置。
背景技术
在无线通信系统中，参考信号一直是保证通信质量的必要手段之一。和传统的LTE(Long Term Evolution，长期演进)系统相比，NR(New Radio，新型无线电通信)系统既要支持低频段(<6GHz)，也要支持高频段(>6GHz)传输。在高频段，相位噪声对信道估计性能的影响不容忽视，因此在3GPP(3rd Generation Partner Project，第三代合作伙伴项目)NR讨论中已经同意发送PTRS(Phase-Tracking Reference Signal，相位跟踪参考信号)用于接收端进行相位跟踪，通过在信道估计中进行相位补偿来提升信道估计精度。
在3GPPNR讨论中已同意给UE(User Equipment，用户设备)配置一个或两个DMRS(Demodulation Reference Signal，解调参考信号)端口组，一个PTRS端口与一个DMRS端口组中的一个DMRS端口有关，并且在一个给定RB(Resource Block，资源块)内，该PTRS端口被承载在该DMRS端口对应的一个子载波上。上行PTRS端口数目与上行DMRS端口组的数量和UE侧发送上行DMRS所使用的射频通道的振荡器数量有关。下行PTRS端口数目与下行DMRS端口组的数量和基站侧发送下行DMRS所使用的射频通道的振荡器数量有关。此外，PTRS还与给数据传输分配的MCS(Modulation and Coding Scheme，调制编码方式)和调度带宽有关，只有MCS和调度带宽的取值在一定范围内时，才发送PTRS，否则不发送PTRS。
发明人通过研究发现，在NR系统中，当上行DMRS端口组的数量为2时，这两组DMRS端口是否可以共用一个上行PTRS端口与UE侧发送这两组DMRS所使用的振荡器数目有关。此时，如果基站无法获知UE侧发送这两组DMRS所使用的射频通道是否共振荡器，为了保证 信道估计性能，基站需要配置2个上行PTRS端口分别对应这两组DMRS端口。如果UE侧发送这两组DMRS只使用了一个振荡器，那么这两组DMRS对应的相位噪声可以认为是相同的，因此只需配置1个上行PTRS端口，从而减少导频开销，提升系统性能。因此，如何让基站获得UE侧的振荡器相关信息是一个需要解决的问题。此外，由于NR系统要支持小时隙(mini-slot)，URLLC(Ultra-Reliable and Low Latency Communications，高可靠性低延时通信)业务，非授权上行传输以及动态TDD等，干扰的变化相比传统的LTE系统可能更快，因此为了更为精确的干扰信息，用于干扰测量的导频需要在时域上较密集，在频域上可以较稀疏。
针对上述问题，本申请公开了一种解决方案。需要说明的是，在不冲突的情况下，本申请的UE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。进一步的，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。
