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***中的传输方法和装置，尤其涉及无线通信中非地面网络(NTN，Non-Terrestrial Networks)中的传输方法和装置。
背景技术
未来无线通信***的应用场景越来越多元化，不同的应用场景对***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，然后在R16或R17版本中启动WI对相关技术进行标准化。
发明内容
在NTN网络中，当用户设备(UE，User Equipment)自身具有定位能力，且能够估计与卫星之间的传输延迟时，用户设备能够在给卫星发送上行信号时自行将发送提前，实现自行确定并调整TA(Timing Advance，定时提前)的操作，以保证到达卫星的信号能够对齐卫星自身的定时。
传统的LTE(Long-Term Evolution，长期演进)及5G***中，当一次PRACH的发送没有成功后，终端往往通过功率抬升(Power Ramping)的方式以更高的发送功率值发送PRACH以期待被基站正确接收。然而，当终端因为自行调整的TA不准确造成多次PRACH发送没有收到反馈后，终端可以采用传统的不调整TA下的PRACH发送，而此时，先前被累计的功率值抬升将需要被重新考虑是否需要计入新的发送功率值中。
针对上述问题的一个解决方案，本申请提供了一种解决方案。需要说明的是，上述问题描述中，NTN场景仅作为本申请所提供方案的一个应用场景的举例；本申请也同样适用于例如地面网络的场景，取得类似NTN场景中的技术效果。类似的，本申请也同样适用于例如存在UAV(Unmanned Aerial Vehicle，无人驾驶空中飞行器)，或物联网设备的网络的场景，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场景和地面网络场景)采用统一解决方案还有助于降低硬件复杂度和成本。
