Description
本申请涉及无线通信系统中的传输方法和装置,尤其涉及无线通信系统中和Multi-TRP(Multiple Transmission Reception Point,多发射接收点)有关的方案和装置。
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。多天线技术是3GPP(3rd Generation Partner Project,第三代合作伙伴项目)LTE(Long-term Evolution,长期演进)系统和NR(New Radio,新无线电)系统中的关键技术。通过在通信节点处,比如基站或UE(User Equipment,用户设备)处,配置多根天线来获得额外的空间自由度。多根天线通过波束赋型,形成波束指向一个特定方向来提高通信质量。多天线系统提供的自由度可以用来提高传输可靠性和/或吞吐量。当多根天线属于多个TRP(Transmitter Receiver Point,发送接收节点)/panel(天线面板)时,利用不同TRP/panel之间的空间差异,可以获得额外的分集增益。在NR R(release)16和R17中,基于多波束/TRP/panel的下行和上行传输分别被支持,用于提高传输的可靠性和传输速率。在NR R18中,基于多波束/TRP/panel的传输的进一步增强被讨论。
为了增加可用频谱来满足日益增长的业务量的需求,从LTE R13及R14开始非授权频谱(共享频谱)上的通信被引入。在非授权频谱中,发射机(基站或者UE)在进行传输之前需要先进行信道接入过程以保证不对其他在非授权频谱上正在进行的传输造成干扰。在NR R17中,基于波束的信道接入过程被引入,以满足不同频率范围(频率范围2-2)的需求。
发明内容
发明人通过研究发现,当被应用于非授权频谱时,当前的基于多波束/TRP/panel的传输技术需要进行增强。
针对上述问题,本申请公开了一种解决方案。需要说明的是,虽然本申请的初衷是针对multi-TRP传输场景展开说明,本申请也能用于single-TRP(单发射接收点)的传输场景中。进一步的,对不同场景(包括但不限于multi-TRP和single-TRP)采用统一的设计方案还有助于降低硬件复杂度和成本。在不冲突的情况下,本申请的任一节点中的实施例和实施例中的特征可以应用到任一其他节点中。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。
