Description

一种用于无线通信的通信节点中的方法和装置
本申请要求于2024年05月29日提交国家知识产权局、申请号为202410685277.6、申请名称为“一种用于无线通信的通信节点中的方法和装置”的中国专利申请的优先权，其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系统中的传输方法和装置，尤其涉及无线通信中的灵活的传输方向配置的传输方案和装置。
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(NR，New Radio)技术的WI(Work Item，工作项目)，开始对NR进行标准化工作。在3GPP RAN#86次全会上决定开始NR Rel-17的SI(Study Item，研究项目)和WI(Work Item，工作项目)的工作并且在3GPP RAN#94e次全会上对NR Rel-18的SI和WI进行立项。在3GPP RAN#102次全会上决定开始NR Rel-19的SI和WI的工作。
在NR Rel-19中包括了支持非重叠子带全双工(SBFD，Subband non-overlapping Full Duplex)的WI。非重叠子带全双工也是6G潜在支持的技术之一。
发明内容
在现有的NR系统中，频谱资源被静态地划分为FDD频谱和TDD频谱。而对于TDD频谱，基站和用户设备都工作在半双工模式。这种半双工模式避免了自干扰并能够缓解跨链路(Cross Link)干扰的影响，但是也带来了资源利用率的下降和延时的增大。针对这些问题，在TDD频谱或FDD频谱上支持灵活的双工模式成为一种可能的解决方案。
针对支持灵活的双工模式中的随机接入配置问题，本申请公开了一种解决方案。需要说明的是，在本申请的描述中，只是将灵活的双工模式作为一个典型应用场景或者例子；本申请也同样适用于6G网络或面临相似问题的其它场景(例如存在链路方向发生变化的场景，或者其它的支持多级配置传输方向的场景，或者具有更强能力基站或用户设备，比如支持同频全双工的场景，或者针对不同的应用场景，比如eMBB、URLLC、非陆地网络、通感一体化网络、智能超表面、太赫兹网络，也可以取得类似的技术效果。此外，不同场景(包括但不限于eMBB、URLLC、非陆地网络、通感一体化网络、智能超表面、太赫兹网络的场景)或不同的应用参数采用统一解决方案还有助于降低硬件复杂度和成本。在不冲突的情况下，本申请的终端的设备中的实施例和实施例中的特征可以应用到基站的设备中，反之亦然。
