Description

一种被用于无线通信的通信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，尤其涉及随机接入的传输方法和装置。
背景技术
覆盖(Coverage)是运营商在进行蜂窝通信网络商业化时考虑的关键因素之一，因为它直接影响服务质量(service quality)以及资本支出(CAPEX)和运营成本(OPEX)。在实际部署的大多数场景中，上行链路(Uplink，UL)性能可能是瓶颈，而在一些新兴的垂直用例中，上行链路流量很大，例如视频上传。在Rel-17“NR(New Radio，新空口)覆盖增强”工作项目(work item，WI)中，针对PUSCH(Physical uplink shared channel，物理上行链路共享信道)、PUCCH(Physical uplink control channel，物理上行链路控制信道)和Msg3(Message 3，消息3)的NR覆盖率进行了扩展增强。然而，PRACH(Physical random access channel，物理随机接入信道)覆盖的提高尚未得到解决。由于PRACH传输在许多过程中都是非常重要的，如初始接入和波束失败恢复，Rel-18成立了“NR覆盖的进一步增强(Further NR coverage enhancements)”工作项目，进一步增强PRACH的上行覆盖。
发明内容
为提高随机接入成功概率，在一次发送Preamble之后，再次发送Preamble时，根据一个计数器和一个功率步长确定Preamble的发送功率的增量。针对Rel-18PRACH增强，一种可行的方式是PRACH重复。当UE通过PRACH重复发送Preamble时。确定Preamble的发送功率的增量的现有机制不能满足通过PRACH重复发送Preamble的需求，难以保证随机接入性能。因此，在通过PRACH重复发送一次Preamble之后，再次通过PRACH重复发送Preamble时，如何确定发送功率的增量需要进行增强，尤其是如何更新一个计数器，或者，如何确定一个功率步长。
针对上述问题，本申请提供了一种随机接入的解决方案。针对上述问题描述中，采用NR系统作为一个例子；本申请也同样适用于例如LTE系统的场景；进一步的，虽然本申请的初衷是针对Uu空口，但本申请也能被用于PC5口。进一步的，虽然本申请的初衷是针对终端与基站场景，但本申请也同样适用于V2X(Vehicle-to-Everything，车联网)场景，终端与中继，以及中继与基站之间的通信场景，取得类似的终端与基站场景中的技术效果。进一步的，虽然本申请的初衷是针对终端与基站场景，但本申请也同样适用于IAB(Integrated Access and Backhaul，集成接入和回传)的通信场景，取得类似的终端与基站场景中的技术效果。进一步的，虽然本申请的初衷是针对地面网络(Terrestrial Network，地面网络)场景，但本申请也同样适用于非地面网络(Non-Terrestrial Network，NTN)的通信场景，取得类似的TN场景中的技术效果。此外，不同场景采用统一解决方案还有助于降低硬件复杂度和成本。
作为一个实施例，对本申请中的术语(Terminology)的解释参考3GPP的规范协议TS36系列的定义。
作为一个实施例，对本申请中的术语的解释参考3GPP的规范协议TS38系列的定义。
作为一个实施例，对本申请中的术语的解释参考3GPP的规范协议TS37系列的定义。
作为一个实施例，对本申请中的术语的解释参考IEEE(Institute of Electrical and Electronics Engineers,电气和电子工程师协会)的规范协议的定义。
需要说明的是，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。
