Description

信息指示方法、节点和存储介质
本申请要求在2020年08月07日提交中国专利局、申请号为202010790934.5的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，例如涉及一种信息指示方法、节点和存储介质。
背景技术
在无线通信领域，为了确保终端设备能够更好的接收和解调信号，终端设备通常需要获取天线端口的准共址(Quasi Co-Location，QCL)关系，以便于根据该QCL关系对数据进行解调处理。在长期演进(Long Term Evolution，LTE)和新空口(New Radio，NR)协议中，规定了对于不同的参考信号的类型，QCL参考类型的获取有以下几种情况：例如，通过无线资源控制(Radio Resource Control，RRC)配置，如周期性信道状态信息参考信号(Channel State Information-Reference Signals，CSI-RS)/追踪参考信号(Tracking Refernece Signal，TRS)；通过RRC配置，由媒体接入控制控制元素(Media Access Control-Control Element，MAC-CE)激活，如通过MAC-CE指示激活和去激活的周期CSI-RS/TRS，或指示激活和去激活的物理下行链路控制信道(Physical Downlink Control Channel，PDCCH)的解调参考信号(Demodulation Reference Signal，DMRS)；通过RRC配置，由MAC-CE激活，并利用下行控制信息(Downlink Control Information，DCI)进行指示，如非周期CSI-RS/TRS，或者，物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的DMRS。
MAC-CE有PDCCH和PDSCH两类，以NR R16标准为例，MAC-CE的内容如图1、2、3所示。但是，目前都是默认由终端设备根据QCL关系进行解调优化。在未接收到网络设备的进一步命令之前，终端设备默认PDCCH和PDSCH的DMRS与初始接入的同步信号(Synchronization Signal，SS)/物理广播信道(Physical Broadcast Channel，PBCH)具有QCL关系。若网络设备进行某些操作(例如，预补偿(pre-compensation))而终端设备无法获知，那么会导致网络设备和终端设备同时进行QCL操作从而造成解调性能下降或解调错误。
