Description
本申请涉及无线通信***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。
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
现有协议中,通过基于回退时间(backoff time)的随机接入(RandomAccess,RA)回退(backoff)机制解决小区过载(overload)问题,如果用户设备(User Equipment,UE)在随机接入过程中接收到一个回退指示(Backoff Indicator,BI),将PREAMBLE_BACKOFF设置为通过查表确定的一个回退参数值(Backoff Parameter value)和由RRC(Radio Resource Control,无线电资源控制)消息配置的一个回退因子(SCALING_FACTOR_BI)的乘积;如果随机接入过程没有被完成,根据PREAMBLE_BACKOFF确定一个回退时间,在这个回退时间之后才执行随机接入资源选择过程。随机接入回退机制在解决小区过载问题的同时,增加了当前的随机接入过程的时延。
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,由于PRACH重复会导致一次PRACH尝试所占用时频资源增加,当大量用户设备发起随机接入时,小区的过载状态(overload condition)以及针对PRACH重复的随机接入资源配置和传统网络相比会发生变化,现有的基于回退时间的随机接入回退机制不能很好的解决PRACH重复的小区负载均衡问题。因此,针对PRACH重复的小区负载均衡问题,随机接入回退机制需要增强。
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***作为一个例子;本申请也同样适用于例如LTE(Long Term Evolution,长期演进)***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。
