为便于理解本申请实施例的技术方案,以下对本申请实施例的相关技术进行说明,以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。
下面介绍URLLC中的CG增强:
在本申请实施例中,需要考虑在干扰受控的NRU场景下支持URLLC业务。具体地,可以考虑在NRU场景下考虑NRU CG和ULRRC CG增强的使用方式,例如:引入NRU和URLLC中协调UL CG增强,以适用于未授权频谱。
为了支持URLLC业务的高时延要求,URLLC增强了CG周期,支持任意slot-level的业务周期。
为了支持多种URLLC业务和URLLC业务的高时延要求,URLLC引入了multiple(多个)CG。不同CG配置的HARQ(Hybrid Automatic Repeat Request,混合自动重传请求)进程不同,并通过HARQ-ProcID-Offset2(HARQ进程标识-偏移2)保证不同CG的进程不同。
由于存在CG资源和其他资源冲突的情况,为了保证CG资源中已经组包的MAC(Medium Access Control,介质访问控制)PDU(Protocol Data Unit,协议数据单元)(例如Deprioritized(低优先的)MAC PDU)不被丢弃/尽快传输,引入了针对CG的自动传输。对该组包MAC PDU的、由于资源冲突不能传输的CG,可以使用后续的、相同HARQ进程的、同一个CG配置中的CG资源,进行新传传输。通过自动传输参数(例如autonomousTx)确定使用自动传输。
下面介绍NRU的相关内容:
NRU项目的目标是使得NR工作在非授权频段,例如包括如下几种工作场景:
场景A:载波聚合场景,PCell(Primary cell,主小区)为授权频谱,通过载波聚合方式聚合工作在非授权频谱上的SCell(Secondary Cell,辅小区);
场景B:双连接工作场景,PCell为LTE授权频谱,PScell(Primary Secondary Cell,主辅小区)为NR非授权频谱;
场景C:独立工作场景,NR作为一个独立小区工作在非授权频谱;
场景D:NR单小区场景,UL(Uplink,上行链路)工作在授权频谱,DL(Downlink,下行链路)工作在非授权频谱;
场景E:双连接工作场景,PCell为NR授权频谱,PScell为NR非授权频谱。
一般来说,NRU的工作频带(Band)为5GHz非授权频谱和6GHz非授权频谱。在非授权频谱上,NRU的设计应该保证与其他已经工作在这些非授权频谱上的系统之间的公平性,比如,WiFi(WirelessFidelity,无线保真)等。公平性的原则包括,NRU对于已经部署在非授权频谱上的系统(比如,WiFi)的影响不能超过这些系统之间的影响。
为了保证在非授权频谱上各系统之间的公平性共存,能量检测已经被同意作为一个基本的共存机制。一般的能量检测机制为LBT(Listen Before Talk,先听后说)机制。该机制的基本原理为,基站或者终端(传输端)在非授权频谱上传输数据之前,需要先按照规定侦听一段时间。如果侦听的结果表示该信道为空闲状态,则传输端可以给接收端传输数据。如果侦听的结果表示该信道为占用状态,则传输端需要根据规定回退一段时间再继续侦听信道,直到信道侦听结果为空闲状态,才能向接收端传输数据。
目前在NRU中包括四种信道接入机制(category):
机制(Category)1:直接传输机制
这种机制用于TX侧可以在COT内的转换间隙(switching gap)之后迅速传输;Switching gap是指接收到传输的转换时间,典型值为不超过16us。
机制(Category)2:不需要随机回退(back-off)的LBT机制
这种机制是指UE侦听信道的时间是确定的,一般比较短,比如25us。
机制(Category)3:随机back-off的LBT机制(竞争窗口固定)
在LBT流程中,传输侧随机的在竞争窗口中去一个随机值来决定侦听信道的时间。
机制(Category)4:随机back-off的LBT机制(竞争窗口不固定)
在LBT流程中,传输侧随机的在竞争窗口中取一个随机值来决定侦听信道的时间,竞争窗口是可变的。
综上,对于终端而言,基站给终端传输数据需要在最大信道占用时间(Maximum Channel Occupancy Time,MCOT)时间之内。如果基站没有抢占到信道,也就是在MCOT时间之外,终端是不会收到基站给该终端的调度数据的。
下面介绍NR-U中的上行LBT失败:
对于UE发起的上行传输,主要有包括如下几类:
SR(Scheduling Request,调度请求):用于请求上行资源;
PRACH(Physical Random Access Channel,物理随机接入信道)传输:由于RACH(Random Access  Channel,随机接入信道)触发,UE需要发送msg1(消息1);
PUSCH(PhysicalUplinkSharedChannel,物理上行共享信道)传输:包括基于CG的上行数据传输以及基于DG(Dynamic Grant,动态授权)的上行数据传输;
物理层信令传输:包括ACK/NACK(确认/非确认)反馈,CSI(Channel State Information,信道状态信息)上报等;
在非授权频带上,UE传输SR、PRACH或者PUSCH之前需要先用LBT来侦听信道是否可用。如果不可以用,即LBT失败,则UE需要等到下一个传输机会再次执行LBT。若检测到LBT失败,需要通知给MAC层LBT失败的信息。
下面介绍NRU中的CG增强:
为了灵活资源选择,NRU CG的HARQ进程不是根据公式计算的,而是UE自己选择的。对一个CG资源,RRC配置一个HARQ进程集合,UE可以在该集合中选择一个HARQ进程用于本次CG传输。具体配置的HARQ进程区间由harq-ProcID-Offset和nrofHARQ-Processes确定。
为了支持back-to-back的资源配置,NRU引入了multiple CG。多个CG配置可以共享HARQ进程。
引入了CG重传定时器(cg-RetransmissionTimer,简称CG retx Timer),以支持由于LBT失败导致的CG资源不能传输时的资源的自动重传。在cg-RetransmissionTimer超时后,若CG定时器(configuredGrantTimer,简称CG timer)未超时,可以对对应的HARQ进程进行重传。
CG传输可以被动态调度DCI(Downlink Control Information,下行控制信息)和DFI(Downlink Feedback Information,下行反馈信息)打断。例如,如下表1所示,CG定时器(CG timer)DFI为ACK时停止(stop),在DFI为NACK时不受影响(No impact),DCI为新传(new tx)或重传(retx)时开始(start)或重新开始(restart)。在CG定时器超时时,停止CG重传定时器(CG retx timer)。CG重传定时器(CG retx timer)在DFI为ACK、NACK、新传或重传时停止(stop)。

Figure PCTCN2020124072-appb-000001
在NRU中的CG定时器(CG timer)和CG重传定时器(CG retx timer)都在PUSCH传输的第一个符号开始的时候开启。但是若该PUSCH对应低优先资源,可能有部分符号传输,但是完整的符号没有传输。因此,在PUSCH的第一个符号传输,可能造成后面的CG资源不能用于这个低优先资源的UE自动传输(因为CG timer开启了),导致这个低优先资源的传输时延(需要在CG retx timer超时后,才能自动重传)。另外,如果认为定时器开启就是传输执行了,那么,UE自动传输功能就不起作用了。

又例如:若autonomous TX,该CG对应的传输未执行,或者,若该CG对应的传输未执行且未收到来自低层的LBT失败指示,UE认为对应的HARQ进程为not pending,同时若CG timer和CG retx timer定时器正在运行,停止CG timer和CG retx timer。在后面的CG资源,使用URLLC自动传输进行UE自动传输。
在本示例中,CG retx timer和autonomous TX配置情况下,可以对低优先MAC PDU/CG进行传输,避免了该资源传输的时延。
