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，尤其涉及覆盖增强的传输方法和装置。
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(Message3，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效恢复，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的上行链路覆盖。
发明内容
在随机接入(Random Access)过程中执行PRACH重复(Repetition)是增强PRACH的上行链路覆盖的一种有效手段，多个PRACH重复关联到多个SSB(Synchronization Signal Block，同步信号块)可以在空域上提高随机接入成功概率。当PRACH重复关联到多个SSB时，如何确定监听PDCCH(Physical Downlink Control Channel，物理下行链路控制信道)的空间参数需要进行增强。
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。
