Description

反馈信息的发送、接收方法、装置及介质 技术领域
本公开涉及无线通信技术领域,尤其涉及反馈信息的发送、接收方法、装置及介质。
背景技术
新型互联网应用的不断涌现对于无线通信技术提出了更高的要求,驱使无线通信技术不断演进以满足应用的需求。当下,蜂窝移动通信技术正在处于新一代技术的演进阶段。
车联网通信也称为车与其它设备(vehicle to everything,V2x)包括以下三种通信方式:车载设备间(vehicle to vehicle,V2V)通信方式、车载设备和路边设备间(vehicle to Infrastructure,V2I)通信方式、车载设备和行人间(vehicle to pedestrian,V2P)通信方式。车联网通信技术可以有效提升交通安全,改善交通效率以及丰富人们的出行体验。
利用现有的蜂窝通信技术支持车联网通信可以有效利用现有基站部署,减少设备开销,也更有利于提供具有服务质量(Quality of Service,QoS)保证的服务,满足车联网业务的需求。因此,在长期演进(LongTerm Evolution,LTE)术中的Rel-14/15中提供了蜂窝网络对于车联网通信V2x的支持,即基于蜂窝网络的V2x(cellular based V2x,C-V2x)。在C-V2x中车载设备和其他设备之间的通信可以通过基站以及核心网进行中转,即利用原有蜂窝网络中终端设备和基站之间的通信链路(例如上行链路UL或下行链路DL)进行通信,也可以直接通过设备之间的直连链路(sidelink)进行通信。与上行链路/下行链路相比,直连链路通信具有时延短、开销小等特点,非常适合用于车载设备和地理位置接近的其他周边设备进行直接通信。
LTE中的V2x sidelink通信只能支持一些基础的安全方面的V2x应用,如协同感知消息(Cooperative Awareness Messages,CAM)或分散式环境通知消息(Decentralized Environmental Notification Message,DENM)等基础安全信息(BSM–Basic Safety Message)进行语音广播通信等。近来随着自动驾 驶等技术的发展,为了支持新的V2x业务,对于V2x技术的性能又提出了新的要求。利用5G新空口(New Radio,NR)技术支持新的V2x通信服务和场景已经被3GPP计划为Rel16的一项重要内容。3GPP工作组已经设立了一些新的V2x通信需要满足的业务需求,包括车队管理(Vehicles Platooning),感知扩展(Extended Sensors),先进驾驶(Advanced Driving),和远程驾驶(remote driving)等。总体来说,NR V2x sidelink需要提供更高的通信速率,更短的通信延时,更可靠的通信质量。

具体实施方式
现结合附图和具体实施方式对本发明实施例进一步说明。
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
在NR V2x的讨论中,RAN WG1(RAN1)决议支持对于直连通信的单播、组 播业务使用物理层的混合自动重传请求(Hybrid automatic repeat request,HARQ)机制。对于HARQ反馈信息,使用物理层直连反馈信道(Physical Sidelink Feedback Channel,PSFCH)来传输。
在NR Uu上行HARQ反馈中,定义了物理上行控制信道(Physical Uplink Control Channel,PUCCH)格式0(format0)和PUCCH format1用于进行小于或者等于2比特的HARQ反馈;其中,format 0使用1或者2个OFDM时域符号进行传输,format 1使用大于等于4个OFDM时域符号进行传输。考虑到NR V2x需要支持很多对于延时要求严格的业务,使用较短的OFDM时域符号会更有利。
NR PUCCH format 0的格式见TS 38.211 6.3.2.3。Format 0使用序列检测的方法传输HARQ信息。Format 0的信号为一个长度为12的序列,占用1个物理资源块(Physical Resource Block,PRB)的频域资源进行传输。上述序列是对一个基序列进行循环移位(cyclic shift)得到的,不同的循环移位的值代表不同的反馈信息。
对基序列进行循环移位的方式如下:
Figure PCTCN2019083956-appb-000001
0≤n<M ZC;其中α是循环移位的值,
Figure PCTCN2019083956-appb-000002
是基序列,M ZC为基序列的长度。
PUCCH format0序列的循环移位取值为:
Figure PCTCN2019083956-appb-000003
其中
Figure PCTCN2019083956-appb-000004
是一常数(例如,一个PRB的子载波数目是12),m 0是基站侧为用户设备配置的初始值,
Figure PCTCN2019083956-appb-000005
是根据传输发生的时间位置(即子帧(subframe)和时隙(slot)号)通过特定的伪随机序列生成的值。基站预先已知m 0,而且可以使用同样的伪随机序列生成
Figure PCTCN2019083956-appb-000006
不同的反馈信息对应不同的循环移位配置值m cs。反馈信息和循环移位配置值m cs的对应关系如下表(引自TS38.213)。
表9.2.3-3,用于表示PUCCH format0中1个HARQ-ACK信息比特与序列循环移位配置值的映射关系
Figure PCTCN2019083956-appb-000007
表9.2.3-3,用于表示PUCCH format0中2个HARQ-ACK信息比特与序列循 环移位配置值的映射关系
Figure PCTCN2019083956-appb-000008
用户设备发送将基序列经过循环移位后的循环移位序列,基站侧确定用户发送的循环移位序列的循环移位配置值,得到m cs,根据上述表中的映射关系恢复出用户的反馈信息。
NR PUCCH format 0的频域带宽为固定的1PRB,在V2x场景中,通信的两端都在移动,所以在这种应用场景下需要应对更加恶劣的信道条件;而且由于采用分布式调度的方式,干扰条件也更加恶化。另外,NR PUCCH format 0使用不同的循环移位配置值来标识反馈信息中的NACK或者ACK,循环移位配置值的测量对于延时的影响较为敏感。NR Uu中每个用户设备会按照从用户设备到基站的延时不同向前调整发送时间以保证到达基站的信号不受到传输延时的影响。但是和NR Uu不同的是,NR V2x中不存在中心节点以及通信的目标接收端分布在整个区域内的情况,所以不做类似的发送时间调整,从而,不同的用户设备间距离会造成不同的延时,对循环移位配置值的测量准确度会造成影响,进而降低HARQ反馈的可靠性。HARQ反馈的可靠性要求相对数据要高一个量级,降低其可靠性会严重影响数据传输的效率。所以,本申请提出了一种新的解决方案来解决NR V2x中传输延时导致的对循环移位配置值的测量准确度的影响,以及降低HARQ反馈的可靠性的问题。
图1是根据一示例性实施例示出的一种反馈信息的发送方法的流程图,此方法应用于两个传输设备中的第一传输设备中,如图1所示,包括:
步骤S11,对基序列进行配置,生成N个循环移位序列,其中,N是大于1的整数;
步骤S12,将所述N个循环移位序列发送给第二设备。
上述两个传输设备是指通过直连链路(sidelink)进行通信的两个传输设备,适用于各种直连通信应用场景。传输设备可以是应用在直连通信应用场景下的各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备,以及各种形式的用户设备 (UserEquipment,UE),移动台(Mobile Station,MS),终端设备(terminal device)等等。
在一种可能的实施方式中,步骤S11包括:
步骤S11-1,确定待传输的反馈信息对应的循环移位配置值的相对值或者相对值集合;
步骤S11-2,根据所述相对值或者相对值集合确定所述N个循环移位配置值;
步骤S11-3,对所述基序列使用所述N个循环移位配置值进行循环移位,得到N个循环移位序列。
本方法中的相对值可以是指循环移位配置值的差值,或者是循环移位配置值的差值与基序列长度的模值,或者是,循环移位配置值的差值的函数运算值,此函数运算可以是移位、倍数等运算。
相对值集合包括N-1个相对值,所述N-1个相对值是按顺序排列的N个循环移位配置值中两两相邻的循环移位配置值之间的相对值。步骤S11-2中根据相对值集合确定N个循环移位配置值包括:使N个循环移位配置值中两两相邻的循环移位配置值之间的相对值分别对应N-1个相对值。
用户设备发送的反馈信道在传输过程中会因为链路质量而出现延迟,反馈信道的信号延时造成的影响相当于在循环移位上增加一个固定的偏移值,本方法中,同一用户设备向相同目标地址发送至少N个循环移位序列,此N个循环移位序列的信号延时可以认为是基本相等的,使用循环移位的相对值关系可以消除信号延时对循环移位检测的影响,从而有效提高反馈信道的可靠性和传输效率。
本方法中的反馈信道包括但不限于HARQ格式。
在步骤S11-1之前,本方法还包括:设置映射关系集合,此映射关系集合包括反馈信息的取值与循环移位配置值的相对值或者相对值集合的映射关系;不同的反馈信息的取值对应不同的循环移位配置值的相对值或者相对值集合。步骤S11-1中确定待传输的反馈信息对应的循环移位配置值的相对值或者相对值集合包括:根据映射关系集合确定待传输的反馈信息的取值所对应的循环移位配置值的相对值或者相对值集合。
本方法使用NR PUCCH format0的基序列,循环移位后的序列如公式(1)所示:
Figure PCTCN2019083956-appb-000009
其中,
Figure PCTCN2019083956-appb-000010
为基序列,M为基序列的长度,
Figure PCTCN2019083956-appb-000011
为循环移位值。循环移位配置值为m cs。下述示例中循环移位配置值的相对值以循环移位配置值的差值为例。
N的取值包括两种情况:
第一种情况:N为2。
应用方式是:循环移位配置值共包括第一循环移位配置值和第二循环移位配置值,循环移位配置值的差值是指第一循环移位配置值与第二循环移位配置值的差值。不同的反馈信息的取值对应不同的差值。
具体示例一
使用NR PUCCH format0的基序列,此基序列的长度L为12。设置N的值为2。
循环移位后的序列如公式(1)中所示。
其中,

Figure PCTCN2019083956-appb-000016
不同的反馈信息的取值对应于不同差值
Figure PCTCN2019083956-appb-000017
反馈比特长度为1比特时,反馈信息和循环移位配置值差值映射关系如表1所示:
表1
Figure PCTCN2019083956-appb-000018
反馈比特长度为2比特时,反馈信息和循环移位配置值差值映射关系如表2所示:
表2
Figure PCTCN2019083956-appb-000019
具体示例二
相比于具体示例一中,使用更长的序列时,会占据更多的频域资源,循环移位的差值也会相应的改变。具体示例二中使用长度L为24的序列,需要占据2个PRB的频域资源。使用NR PUCCH format0的基序列。以N的值是2为例。
反馈比特长度为1比特时,反馈信息和循环移位配置值差值映射关系如表3所示:
表3
Figure PCTCN2019083956-appb-000020
反馈比特长度为2比特时,反馈信息和循环移位配置值差值映射关系如表4所示:
表4:
Figure PCTCN2019083956-appb-000021
表1、表2、表3和表4中所示的映射关系中,在相同的反馈比特长度下,循环移位配置值对的差值为L/(2^M)的向下取整的整数倍,其中,L是基序列长度,M是反馈信息的比特数,即循环移位配置值的差值均匀或者非均匀式的分布于0至L-1的区间内,L是基序列的长度。此均匀分布的方式能够增加对检测误差的容忍度,提高传输方法的鲁棒性。
上述均分分布的方式是一种应用场景中可能的实施方式,在不同的应用场景中采用非均匀分布的方式。例如表1中反馈信息的取值分别为0和1时,第一循环移位配置值与第二循环移位配置值的差值分别取其它不同的值。再例如 表2中,HARQ-ACK值分别为{0,0}、{0,1}、{1,1}、{1,0}时,第一循环移位配置值与第二循环移位配置值的差值分别取其它不同的值。
第二种情况:N大于2。
应用方式是:差值集合包括N-1个循环移位配置值差值,对应于按顺序排列的N个循环移位配置值中两两相邻的循环移位配置值之间的差值。步骤S11-2中根据差值集合确定N个循环移位配置值包括:使N个循环移位配置值中两两相邻的循环移位配置值之间的差值分别对应所述N-1个循环移位配置值差值。作为一种可能的实现方式:按序排列的N个循环移位配置值中两两相邻的循环移位配置值之间的差值相同。
具体示例三
使用NR PUCCH format0的基序列,此基序列的长度L为12。N的值为3。
反馈比特长度为1比特时,反馈信息和循环移位配置值差值的映射关系如表5所示:

反馈比特长度为2比特时,反馈信息和循环移位配置值差值的映射关系如表6所示:
表6

除了如上述表5,表6所示的,设置同一反馈信息对应的相邻循环移位配置值的差值均相同的情况外,在其它情况下,设置同一反馈信息对应的相邻循环 移位配置值的差值中每对循环移位配置值的差值不相同。

在步骤S12中,发送N个循环移位序列的方式是重复发送的方式,包括以下方式中的一种:

方式二,在Y个时域资源上分别确定一段频域资源,将每段频域资源分为N份,每一所述N个循环移位序列占用一段频域资源,每个循环移位序列占用一份。

在步骤S12中,发送N个循环移位序列的方式还是采用发送附加序列的方 式,包括:构建T组附加序列,每组附加序列中包含的循环移位序列的个数均为N,每组附加序列中第i个循环移位序列与所述N个循环移位序列中的第i个循环移位序列的循环移位配置值的差值相同;i为大于0小于N的整数;在步骤S12中发送N个循环移位序列包括:发送N个循环移位序列和T组附加序列。
图7是一种用于发送循环移位序列的时频资源的示意图。如图7所示,N的值为2,在本方法的基础上即在构建有序列1和序列2的基础上,再构建一组序列,此组序列中包含2个循环移位序列即序列3和序列4,序列3和序列1所处的频域资源相同,序列4和序列2所处的频域资源相同。序列3的循环移位配置值与序列1的循环移位配置值的差值等同于序列4的循环移位配置值的与序列2的循环移位配置值的差值。从而,序列3与序列4的循环移位配置值的差值等同于序列1与序列2的循环移位配置值的差值。
