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，尤其涉及无线通信中的随机接入的传输方案和装置。
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技术(NR，New Radio)的WI(Work Item，工作项目)，开始对NR进行标准化工作。
为了能够适应多样的应用场景和满足不同的需求，在3GPP RAN#75次全会上还通过了NR下的非地面网络(NTN，Non-Terrestrial Networks)的研究项目，该研究项目在R15版本开始。在3GPP RAN#79次全会上决定开始研究NTN网络中的解决方案，在3GPP RAN#86次全会上决定启动WI对相关技术进行标准化。
发明内容
在NTN网络或者类似于NTN具有很大的传输延时和很大的传输延时差异的网络中，由于大的传输延时差异和上下行同步传输的要求可能导致现有的(比如NR 5G Release 16版本)的基于传统地面通信(Terrestrial Networks)的设计无法直接重用，尤其传统的随机接入设计可能无法适用于NTN网络中，因而需要新的设计来支持大的传输延时和大的传输延时差异的网络，保证通信正常工作。
针对大延时网络中的由于大延时和大延时差所造成的现有设计无法工作或者无法有效地工作的问题，本申请公开了一种解决方案。需要说明的是，在本申请的的描述中，只是NTN场景作为一个典型应用场景或者例子；本申请也同样适用于面临相似问题的NTN之外的其它场景(比如其它大延时网络)，也可以取得类似NTN场景中的技术效果。此外，不同场景(包括但不限于NTN的场景)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，本申请的第一节点设备中的实施例和实施例中的特征可以应用到第二节点设备中，反之亦然。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TS36系列、TS38系列、TS37系列中的定义。
本申请公开了一种用于无线通信中的第一节点中的方法，其特征在于，包括：
接收第一信息；
接收第二信息，所述第二信息被用于确定第一定时偏移值；
确定第一定时补偿值，并且发送第一信号；
其中，所述第一信号的发送起始时刻和参考时刻之间的时间间隔长度等于目标定时补偿值，所述第一信号的发送起始时刻早于所述参考时刻，所述参考时刻是参考时域资源单元的边界时刻，所述第一信息被用于确定所述参考时域资源单元在时域的位置；所述第一定时补偿值和所述第一定时偏移值一起被用于确定所述目标定时补偿值，所述第一定时偏移值大于0；所述第一信号被用于随机接入，所述第一信号携带前导序列。
