一种支持广播信号的无线通信系统中的方法和装置 技术领域
本申请涉及移动通信技术领域中的方法和装置，尤其涉及支持广播信号的系统中的无线通信方案。
背景技术
根据3GPP(3rd Generation Partner Project，第三代合作伙伴项目)RAN1(Radio Access Network，无线接入网)的讨论，NR(New Radio，新型无线电通信)系统的设计要支持良好的前向兼容性。为了达到这个目的，NR系统的设计要具备足够的灵活性。但同时，灵活的设计增加了系统的不确定性，提高了UE(User Equipment，用户设备)的处理复杂度。在充分保证设计灵活性的前提下简化UE的处理复杂度，保证NR系统的正常工作是一个需要研究的方向。
发明内容
发明人通过研究发现，在灵活的系统设计下，NR系统的系统信息不会固定在一个特定的频域资源上发送，UE需要监测不同频域资源来接收系统信息。在现有的3GPP LTE(Long-Term Evolution，长期演进)系统中，RS(Reference Signal，参考信号)序列和RS所占据的子载波在整个系统带宽中的位置是相关联的。当UE(User Equipment，用户设备)对不同频域资源进行监测时，UE很难获知当前监测的频域资源在整个系统带宽中的位置，因此如果采用现有3GPP LTE系统中的方法，UE将无法获知当前监测的频域资源上RS序列，从而无法进行信道估计。
本申请针对上述问题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。
