Description

一种被用于无线通信的节点中的方法和装置 技术领域
本申请涉及无线通信系统中的传输方法和装置，尤其涉及支持蜂窝网的无线通信系统中的无线信号的传输的方法和装置。
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NR技术的WI(Work Item，工作项目)，开始对NR进行标准化工作。
在现有的NR系统中，频谱资源被静态地划分为FDD(Frequency Division Duplexing，频分双工)频谱和TDD(Time Division Duplexing，时分双工)频谱。对于TDD频谱，基站和UE(User Equipment，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干扰(Cross Link Interference,CLI)的影响，但是也带来了资源利用率下降和延时增大等问题。针对这些问题，在TDD频谱或FDD频谱上支持灵活的双工模式或可变的链路方向(上行或下行或灵活)成为一种可能的解决方案。在3GPP RAN#88e次会议和3GPP Rel-18(Release-18，版本18)workshop中，在NR Rel-18中支持更灵活的双工模式或全双工模式得到了广泛的关注和讨论，特别是gNB(NR节点B)端的子带非重叠全双工(SubBand non-overlapping Full Duplex，SBFD)模式。在这个模式下的通信会受到严重的干扰，包括自干扰和CLI。为了解决干扰问题，需要采用先进的干扰消除技术，包括天线隔离，波束赋形，RF(Radio Frequency，射频)级干扰消除和数字干扰消除。
发明内容
在SBFD场景中，干扰环境可以在SBFD符号和非SBFD符号之间显著变化，干扰源也不尽相同；在非SBFD符号中，基站在接收来自终端的上行传输时，干扰主要来在于其他终端的上行传输；在SBFD符号中，基站上行接收除了受到其他终端上行传输的干扰外，还会受到基站下行传输的信号的干扰，这种干扰可能来自于同一小区、同一网络的不同小区或其他基站的小区等。因此，SBFD场景下通过增强上行传输的功率控制(power control)以处理SBFD符号和非SBFD符号之间显著变化的干扰环境是一个值得研究的问题。
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SBFD场景，本申请也能应用其他非SBFD场景；进一步的，对不同场景(比如其他非SBFD场景，包括但不限于容量增强系统、近距离通信的系统、非授权频谱通信、IoT(Internet of Things，物联网)、URLLC(Ultra Reliable Low Latency Communication，超鲁棒低时延通信)网络、车联网等)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。
特别的，对本申请中的术语(Terminology)、名词、函数、变量的解释(如果未加特别说明)可以参考3GPP的规范协议TS38系列、TS37系列中的定义。在需要的情况下，可以参考3GPP标准TS38.211，TS38.212，TS38.213，TS38.214，TS38.215，TS38.300，TS38.304，TS38.305，TS38.321，TS38.331，TS37.355，TS38.423，以辅助对本申请的理解。
