本申请涉及无线通信系统中的传输方法和装置，尤其涉及非授权频谱上的传输方案和装置。
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)(或5G)进行研究,在3GPP RAN#75次全会上通过了新空口技术(NR，New Radio)的WI(Work Item，工作项目)，开始对NR进行标准化工作。
为了能够适应多样的应用场景和满足不同的需求，在3GPP RAN#75次全会上还通过NR下的非授权频谱(Unlicensed Spectrum)的接入的研究项目，该研究项目预期在R15版本完成，然后在R16版本中启动WI对相关技术进行标准化。
发明内容
在LTE(Long Term Evolution，长期演进)的LAA(License Assisted Access，授权辅助接入)项目中，为了确定非授权频谱可用，同时保证在非授权频谱上的同步，LTE基站(eNB)在非授权频域上传输DRS(Discovery Reference Signal，发现参考信号)。DRS只能在配置的可用于DRS传输的资源上进行传输同时要满足非授权频谱的接入法规要求(比如LBT，Listen Before Talk，先听后说)。在NR的非授权频谱接入中类似于DRS的信号也是需要的。在NR的非授权频谱中包括高频段的频谱(一般高于6GHz)，由于高频段频谱的传输损耗非常大，采用大规模天线来实现覆盖变得非常必要。但是为了实现简单与成本的限制，基于模拟波束赋形(Analog Beamforming)的波束扫荡(Beam Sweeping)会被广泛采用。当采用波束扫荡进行类似于DRS的信号传输时需要特别 的设计。
针对NR中的非授权频谱下的发现参考信号的设计，本申请提供了一种解决方案。需要说明的是，在不冲突的情况下，本申请的UE(User Equipment，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。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。
