Description

一种信号发送、接收方法及装置
本申请要求在2018年8月27日提交中国专利局、申请号为201810983798.4、申请名称为“一种信号发送、接收方法及装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域,尤其涉及一种信号发送、接收方法及装置。
背景技术
在长期演进(long term evolution,LTE)系统中,物理上行共享信道(physical uplink shared channel,PUSCH)的解调使用上行解调参考信号(demodulation reference signal,DMRS)进行信道估计。上行DMRS的序列直接映射到频域子载波上。上行DMRS序列是基序列通过时域循环移位生成的序列,基序列由Zadoff-Chu序列(ZC序列)循环扩充获得。该ZC序列,是满足恒包络零自相关(constant amplitude zero auto-correlation,CAZAC)序列性质的序列。该DMRS信号的峰均功率比(peak-to-average power ratio,PAPR)较低,不同小区分配的不同的DMRS序列,互相关较小。
在新无线电接入技术(new radio access technology,NR)中,上行链路支持离散傅里叶变换扩频的正交频分复用(discrete fourier transform spread OFDM,DFT-s-OFDM)下的π/2二进制相移键控(binary phase shift keying,BPSK)调制方法,并且支持DFT-s-OFDMπ/2 BPSK调制时使用滤波,可以获得非常低的PAPR,而LTE系统中的PUSCH的DMRS信号PAPR相比而言就比较大,满足不了低PAPR的要求。上行DMRS可以通过DFT-s-OFDM的π/2 BPSK调制产生,该上行DMRS的序列可以使用基于Gold序列产生的序列。DMRS序列先进行π/2 BPSK调制,然后进行DFT变换,映射到频域子载波,生成DMRS信号。通过DFT-s-OFDMπ/2 BPSK生成的DMRS信号,其PAPR很低。不同的小区可以采用不同的Gold序列生成参考信号,但是使用基于Gold序列生成的序列时,特别是当Gold序列的长度较大时,不同的Gold序列个数远超需求(例如NR系统中的30个),但是Gold序列的互相关和自相关特性,会导致不同的参考信号之间的干扰较大,DMRS信号的频率平坦度较差,从而不利于进行信道估计。
也就是说,采用现有的用于PUSCH的DMRS所使用的序列,不能够满足目前利用PUSCH或物理上行控制信道(physical uplink control channel,PUCCH)或者探测参考信号(sounding reference signal,SRS)发送信号的通信应用环境。

该方法可由第二通信装置执行,第二通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置,当然还可以是其他通信装置,例如芯片系统。
通过使用本申请实施例提供的新的序列,可以在使用PUSCH或PUCCH发送信号时 保持较好的频域平坦度,同时保持较低的PAPR值和较低的信号间互相关性,从而满足利用PUSCH或PUCCH或SRS发送信号的通信应用环境。
在一个可能的设计中,N满足48≤N≤96时,N的取值为48、54、60、72、90或96;和/或,N满足768≤N≤1620时,N的取值为768、810、864、900、960、972、1080、1152、1200、1296、1350、1440、1458、1500或1536;和/或,N满足192≤N≤432时,N的取值为192、216、240、270、288、300、324、360、384或432。
提供了N的一些可能的取值,在本申请实施例中,N的取值不限于此。例如,N满足48≤N≤96时,只要是属于[48,96]范围的整数均可以作为N,或者,[48,96]范围的真子集中的整数均可作为N,例如属于[48,60]范围内的整数均可以作为N,或者属于[54,72]范围内的整数均可以作为N,或者属于[60,96]范围内的整数均可以作为N,等等。对于N满足768≤N≤1620或N满足192≤N≤432的情况来说也是同样。

第一序列集合所包括的序列,可以分配给不同的小区使用。而如果分配给不同的小区的序列的互相关性较高,可能导致小区间的干扰较大。因此本申请实施例中,将第一序列集合所包括的部分序列或全部序列进行分组,得到至少两个序列组,属于不同的序列组的两个序列,可以满足第一移位寄存器序列的初始状态相同,第二移位寄存器序列的初始状态不同,或者满足第一移位寄存器序列的初始状态相同,第二移位寄存器序列的初始状态也相同,但v不同,可以理解为,满足这两种性质种的任意一种性质的两个序列,对应的是不同的根序列,或者说,属于一个序列组的序列是由一个根序列生成的,而属于不同的序列组的序列是由不同的根序列生成的,由不同的根序列生成的序列之间,互相关性较小。那么本申请实施例中,可以将一个序列组仅分配给一个小区,也就是不会将一个序列组分配给两个或多个小区使用,这样,不同的小区所使用的序列之间的互相关性就比较小,减小了小区间的干扰。或者也可以将一个序列组分配给至少两个小区,但这至少两个小区需要不是相邻小区,这样,虽然至少两个小区使用的序列之间的互相关性较高,但由于这些小区不是相邻小区,因此干扰也不会很大。或者,如果序列{s(n)}是由第三移位寄存器序列,那么也可以将第一序列集合进行分组,得到至少两个序列组,也可以使得属于不同的序列组的序列是由不同的根序列生成的,因此互相关性较小。如果序列{s(n)}是由第三移位寄存器序列,本申请实施例对于分组方法不做限制。
在一个可能的设计中,所述方法还包括:第一通信装置根据所述第一移位寄存器序列的初始状态和所述第二移位寄存器序列的初始状态,从所述第一序列集合中选择序列{s(n)},其中,所述第二移位寄存器序列初始状态是根据序列组ID或小区ID确定的;或,第一通信装置根据所述第一移位寄存器序列的初始状态、所述第二移位寄存器序列的初始状态、以及v,从所述第一序列集合中选择序列{s(n)},其中,v是根据序列组ID或小区ID确定的。
第一序列集合例如是网络设备预配置给终端设备的,或者是由协议预先定义的,第一序列集合中包括多个序列,那么终端设备涉及到要从第一序列集合中选择序列{s(n)},以 得到序列{x(n)},从而生成第一信号。在本申请实施例中,终端设备可以根据第一移位寄存器序列的初始状态和第二移位寄存器序列的初始状态来选择序列{s(n)},其中,第一移位寄存器序列的初始状态例如是终端设备已知的,例如为固定序列,而第二移位寄存器序列的初始状态,终端设备可以根据分配给该终端设备所在的小区的序列组的ID或者根据该终端设备所在的小区的ID来确定。或者,终端设备也可以根据第一移位寄存器序列的状态、第二移位寄存器序列的状态、以及v,来选择序列{s(n)},其中,第一移位寄存器序列的初始状态和第二移位寄存器序列的初始状态例如是终端设备已知的,例如均为固定序列,而v,终端设备可以根据分配给该终端设备所在的小区的序列组的ID或者根据该终端设备所在的小区的ID来确定。

在一个可能的设计中,第一通信装置根据序列{x(n)}生成第一信号,包括:对所述序列{x(n)}中的N个元素进行离散傅里叶变换处理,得到序列{f(n)};将所述序列{f(n)}中的N个元素分别映射至连续的N个子载波上,得到所述第一信号,或者,将所述序列{f(n)}中的N个元素分别映射至等间隔的N个子载波上,得到所述第一信号。
给出了生成第一信号的具体的方式。
在一个可能的设计中,所述方法还包括:第一通信装置在对所述序列{x(n)}中的N个元素进行离散傅里叶变换处理之前,对所述序列进行滤波;或者,第一通信装置在对所述序列{x(n)}中的N个元素进行离散傅里叶变换处理之后,对离散傅里叶变换处理之后的序列{x(n)}进行滤波。
在本申请实施例中,可以选择不对序列进行滤波,减少生成第一信号的过程,提高生成第一信号的效率,或者,也可以选择对序列进行滤波,以降低PAPR。在滤波时,可以选择在离散傅里叶变换处理之前进行滤波,也可以选择在离散傅里叶变换处理之后进行滤波,具体的不做限制。
相应的,在一个可能的设计中,第二通信装置接收承载在N个子载波上的第一信号,获取所述第一信号承载的序列{x(n)}中的N个元素,包括:在连续的N个子载波上获取所述N个子载波上的所述第一信号,或者,在等间隔的N个子载波上获取所述N个子载波上所述的第一信号;获取序列{f(n)}中的N个元素,N为大于1的正整数,所述第一信号由所述序列{f(n)}映射至所述N个子载波上生成;对所述序列{f(n)}进行离散傅里叶逆变换处理,获取序列{x(n)}中的N个元素。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施例作进一步地详细描述。
以下,对本申请实施例中的部分用语进行解释说明,以便于本领域技术人员理解。
1)终端设备,包括向用户提供语音和/或数据连通性的设备,例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。该终端设备可以经无线接入网(radio access network,RAN)与核心网进行通信,与RAN交换语音和/或数据。该终端设备可以包括用户设备(user equipment,UE)、无线终端设备、移动终端设备、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point,AP)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、或用户装备(user device)等。例如,可以包括移动电话(或称为“蜂窝”电话),具有移动终端设备的计算机,便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,智能穿戴式设备等。例如,个人通信业务(personal communication service,PCS)电话、无绳电话、会话发起协议(session initiation protocol,SIP)话机、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)、等设备。还包括受限设备,例如功耗较低的设备,或存储能力有限的设备,或计算能力有限的设备等。例如包括条码、射频识别(radio frequency identification,RFID)、传感器、全球定位系统(global positioning system,GPS)、激光扫描器等信息传感设备。
作为示例而非限定,在本申请实施例中,该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备,是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称,如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上,或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备,更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能,例如:智能手表或智能眼镜等,以及只专注于某一类应用功能,需要和其它设备如智能手机配合使用,如各类进行体征监测的智能手环、智能头盔、智能首饰等。
2)网络设备,例如包括基站(例如,接入点),可以是指接入网中在空中接口上通过一个或多个小区与无线终端设备通信的设备。网络设备可用于将收到的空中帧与网际协议(internet protocol,IP)分组进行相互转换,作为终端设备与接入网的其余部分之间的路由器,其中接入网的其余部分可包括IP网络。网络设备还可协调对空中接口的属性管理。例如,网络设备可以包括长期演进(long term evolution,LTE)系统或演进的LTE系统(LTE-Advanced,LTE-A)中的演进型基站(NodeB或eNB或e-NodeB,evolutional Node B),或者也可以包括第五代移动通信技术(fifth generation,5G)新无线(new radio,NR)系统中的下一代节点B(next generation node B,gNB)或者也可以包括云接入网(cloud radio access netowrk,CloudRAN)系统中的集中式单元(centralized unit,CU)和分布式单元(distributed unit,DU),本申请实施例并不限定。
本文中所述的网络设备,不限于终端设备的服务小区或者服务基站,也可以是任何可以存储终端设备的能力信息的网络设备,例如移动性管理实体(mobility management entity,MME)。
3)本申请实施例中的术语“系统”和“网络”可被互换使用。“多个”是指两个或两 个以上,鉴于此,本申请实施例中也可以将“多个”理解为“至少两个”。“至少一个”,可理解为一个或多个,例如理解为一个、两个或更多个。例如,包括至少一个,是指包括一个、两个或更多个,而且不限制包括的是哪几个,例如,包括A、B和C中的至少一个,那么包括的可以是A,B,C,A和B,A和C,B和C,或A和B和C。“至少两个”,可理解为两个或更多个。同理,对于“至少一种”等描述的理解,也是类似的。“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,或单独存在B这三种情况。另外,字符“/”,如无特殊说明,一般表示前后关联对象是一种“或”的关系。
另外,为了便于清楚描述本申请实施例的技术方案,在本申请的实施例中,采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定,并且“第一”、“第二”等字样也并不限定一定不同。此外,本申请实施例和权利要求书及附图中的术语“包括”和“具有”不是排他的。例如,包括了一系列步骤或模块的过程、方法、系统、产品或设备没有限定于已列出的步骤或模块,还可以包括没有列出的步骤或模块。
如上介绍了本申请实施例涉及的一些概念,下面介绍本申请实施例中涉及的技术特征。
在通信系统中,通常使用参考信号求取信道估计矩阵,从而解调数据信息。目前,在LTE系统、4G系统、4.5G系统、5G系统,以及NR系统或NR类似场景中,支持在上行DFT-s-OFDM下的π/2 BPSK调制。上行可以采用DFT-s-OFDM下的π/2 BPSK调制的DMRS,该DMRS可以使用基于Gold序列的序列。但是,若该上行DMRS使用基于Gold序列的序列,会导致不同的DMRS信号之间的干扰较大,DMRS信号的频率平坦度较差,从而不利于进行信道估计。
为了确保LTE系统、4G系统、4.5G系统、5G系统,以及NR系统或NR类似系统中,甚至其他具有更高要求的通信系统或通信应用环境中,在利用PUSCH或PUCCH发送信号时,能够使信号保持较低的互相关特性,较好的频域平坦度,同时保持较低的PAPR值,本申请实施例提供了一种信号发送、接收的方法,在该方法中提供了新的序列。通过将本申请实施例提供的新的序列用于PUSCH的DMRS或PUCCH或者SRS,可以满足在使用PUSCH或PUCCH发送信号时保持较低的信号间的互相关性,较好的频域平坦度,同时保持较低的PAPR值,从而满足利用PUSCH或PUCCH或者SRS发送信号的通信应用环境。
本申请实施例提供的技术方案可应用于LTE系统、4G系统、4.5G系统、5G系统、NR系统或NR类似的系统,还可以应用于未来的通信系统,或者还可以应用于其他类似的通信系统。
请参考图1,为本申请实施例的一种应用场景。图1中包括网络设备和终端设备,终端设备能够与网络设备进行空口通信。当然图1中的终端设备的数量只是举例,在实际应用中,网络设备可以为多个终端设备提供服务,多个终端设备中的全部终端设备或者部分终端设备都可以采用本申请实施例提供的序列向网络设备发送信号。网络设备和终端设备之间的传输,可以通过无线电波来传输,也可以通过可见光、激光、红外、光量子、电力线、光纤、同轴电缆或铜绞线等传输。
图1中的网络设备例如为接入网(access network,AN)设备,例如基站。其中,接入网设备在不同的系统中对应不同的设备,例如在第四代移动通信技术(4G)系统中可以对应eNB,在5G系统中对应5G中的接入网设备,例如gNB,类似的,在其他的通信系统 中还可能对应其他的设备。
下面结合附图介绍本申请实施例提供的技术方案。
本申请实施例提供第一种信号发送、接收方法,该方法的流程图请参见图2a。该方法可应用于图1所示的场景,在下文的介绍过程中,就以本申请实施例提供的方法应用于图1所示的应用场景为例。另外,该方法可由两个通信装置执行,这两个通信装置例如为第一通信装置和第二通信装置,其中,第一通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置(例如芯片系统),或者第一通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置(例如芯片系统)。对于第二通信装置也是同样,第二通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置(例如芯片系统),或者第二通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置(例如芯片系统)。且对于第一通信装置和第二通信装置的实现方式均不做限制,例如第一通信装置可以是终端设备,第二通信装置是网络设备,或者第一通信装置和第二通信装置都是网络设备,或者第一通信装置和第二通信装置都是终端设备,或者第一通信装置是终端设备,第二通信装置是能够支持网络设备实现该方法所需的功能的通信装置,等等。其中,网络设备例如为基站。
为了便于介绍,在下文中,以该方法由网络设备和终端设备执行为例,具体的,以第一通信装置是终端设备、第二通信装置是网络设备为例。
S21、终端设备根据序列{x(n)}生成第一信号。
其中,序列{x(n)}包括N个元素,N为大于1的整数,x(n)为序列{x(n)}中的元素,序列{x(n)}满足x(n)=A·b(n)·j n
Figure PCTCN2019102892-appb-000025
n的取值为[0,N-1],元素b(n)满足b(n)=u·(1-2s(n)),A和u均为非零复数,
Figure PCTCN2019102892-appb-000026
由元素s(n)组成的序列{s(n)}是第一序列集合中的序列之一。
S21的执行,可选的,可以是终端设备在入网后,确定包括N个元素的序列{x(n)},例如,终端设备从第一序列集合中选择一个序列,根据该选择的序列得到序列{s(n)},从而根据所选择的序列{s(n)}得到包含N个元素的序列{x(n)}。也可以是,网络设备在终端设备接入网络时,由网络设备确定序列{b(n)}并配置给终端设备,由终端设备基于该序列{b(n)}确定包含N个元素的序列{x(n)}。或者是,网络设备在终端设备接入网络时,由网络设备确定序列{s(n)}并配置给终端设备,由终端设备基于该序列{s(n)}确定包含N个元素的序列{x(n)}。
需要说明的是,在计算的过程中,u的取值可以是固定的,或者也可以不是固定不变的,也就是说,u的取值也可以是对不同的序列{s(n)}可变。在具体实现中,u的取值针对当前选取的同一个序列中的所有元素是相同的。u的取值针对不同序列中的元素可以不同。
其中,由元素s(n)组成的序列{s(n)}为第一序列集合中的序列之一。
一种可能的示例中,终端设备在入网后,确定包含N个元素的序列{x(n)}的过程可以如图2b所示。具体流程为:
终端设备确定序列{b(n)}和A。n的取值为0到N-1。A为非零复数。序列{b(n)}可以是该终端设备存储的,也可以是由网络设备配置给该终端设备的,也可以是该终端设备根据预定义的公式计算得到的。
作为第一序列集合的第一种实施方式,第一序列集合包括序列{k(n)},元素k(n)满足 k(n)=c((n+t)mod 63),n=0,1,2,…,N-1,t为整数,t可以看做是一个循环移位。可以理解为,序列{k(n)}是对序列{c(n)}进行截取或扩充得到的,t就表示从序列{c(n)}的第t个元素开始作为序列{k(n)}的元素,例如t=0,则表示从序列{c(n)}的第一个元素开始作为序列{k(n)}的元素,t=1,则表示从序列{c(n)}的第二个元素开始作为序列{k(n)}的元素,以此类推。Mod表示取模运算,因为c(n)是一个长度为63的序列,因此如果序列{k(n)}的长度大于63,就需要对序列{c(n)}进行扩充,例如在取序列{c(n)}的第63个元素之后,再将序列{c(n)}的第一个元素拼接到后面作为第64个元素,从而通过对序列{c(n)}进行循环扩充来得到序列{k(n)}。
其中,元素c(n)满足c(n)=(c 1(n)+c 2(n))mod 2,n=0,1,2,…,62,c 1(n)为序列{c 1(n)}中的元素,c 2(n)为序列{c 2(n)}中的元素,序列{c 1(n)}是第一移位寄存器序列,序列{c 2(n)}是第二移位寄存器序列。第一移位寄存器序列的迭代公式为
Figure PCTCN2019102892-appb-000027
Figure PCTCN2019102892-appb-000028
也就是元素c 1(n)满足该公式,n=0,1,2,...56,第二移位寄存器序列的迭代公式为
Figure PCTCN2019102892-appb-000029
也就是元素c 2(n)满足该公式,n=0,1,2,...,57。
{c 1(n),n=0,1,2,3,4,5}是第一移位寄存器序列的初始状态,{c 2(n),n=0,1,2,3,4}是第二移位寄存器序列的初始状态。
其中,本文中所述的移位寄存器序列,可以是由移位寄存器生成的,或者也可以通过其他方式生成。
在第一序列集合的第一种实施方式下,N满足48≤N≤96,例如N的取值可以是48、54、60、72、90或96,其中,N可以取48、54、60、72、90和96中的任意一个,或者,N可以取48、54、60、72、90或96中的一部分值,例如N可以取48、54或60,也就是说,对于48<N<96这个范围,其中包括的每个取值都可以作为N的值,或者,也可以是其中包括的部分取值可以作为N的值,具体的不做限制。[h 0,h 1,h 2,h 3,h 4,h 5]和[p 0,p 1,p 2,p 3,p 4]分别为[1,0,0,0,0,1]和[1,1,0,0,0]、[1,1,0,0,1,1]和[1,0,0,0,1]、[1,1,0,1,1,0]和[1,1,0,0,0]、[1,0,1,1,0,1]和[1,0,0,0,1]、[1,1,1,0,0,1]和[1,1,0,0,0],或[1,1,0,0,0,0]和[1,0,0,0,1]。或者,[h 0,h 1,h 2,h 3,h 4,h 5]和[p 0,p 1,p 2,p 3,p 4]还可以有其他的取值,具体的不做限制。
例如,[h 0,h 1,h 2,h 3,h 4,h 5]和[p 0,p 1,p 2,p 3,p 4]分别为[1,0,0,0,0,1]和[1,1,0,0,0],对于第一移位寄存器序列来说,
Figure PCTCN2019102892-appb-000030
那么例如,c 1(1+6)=(c 1(1)+c 1(6))mod 2,再例如,c 1(2+6)=(c 1(2)+c 1(7))mod 2,以此类推。对于第二移位寄存器序列来说,
Figure PCTCN2019102892-appb-000031
那么例如,c 2(1+5)=((c(1)+c(2))mod 2,再例如,c 2(2+5)=((c(2)+c(6))mod 2,以此类推。
上述方式所得的序列{c(n)}是最小码距为26的循环码,即{c(n)}的互相关性和自相关性比较好,因此可以保证第一序列集合中的不同序列间的互相关性比较低,根据第一序列集合中的序列得到的第一信号的频域平坦度比较好。同时上述方式所得到的序列是个数可以满足系统需求,至少30个互相关比较低的序列,同时个数较少的序列。
在第一序列集合的第一种实施方式中,第一序列集合中包括的序列{k(n)}是通过两个移位寄存器序列得到的。在本申请实施例中,可以令第一移位寄存器序列的级数大于第二移位寄存器序列的级数,例如第一移位寄存器序列的级数为6,第二移位寄存器序列的级数为5。通过这样的机制生成的序列,当第一移位寄存器序列的初始状态相同时,如果两个 序列对应的第二移位寄存器序列的初始状态不同,则这两个序列的互相关性就比较小,或者可以认为,这两个序列是基于不同的根序列生成的。
因此,本申请实施例提出,如果第一序列集合中包括根据第一序列集合的第一种实施方式所得到的序列,则,可以将第一序列集合包括的序列进行分组。例如第一序列集合可以包括至少两个序列组,其中的每个序列组可以包括至少一个序列,当然,不同的序列组所包括的序列的数量可以相同,也可以不同。在分组时,可以是根据第二移位寄存器序列的初始状态来划分的,或者说,是根据第一移位寄存器序列的初始状态和第二移位寄存器序列的初始状态来划分的。例如,属于至少两个序列组中的不同序列组的两个序列,满足第一移位寄存器序列的初始状态相同,第二移位寄存器序列的初始状态不同。通过这样的方式划分得到的至少两个序列组,任意两个序列组之间的序列的互相关性都是较小的,例如任意两个序列组之间的序列的互相关性小于阈值。那么,可以将每个序列组分配给一个小区,或者说,一个序列组仅分配给一个小区,也就是,一个序列组不会分配给多个小区,那么,不同的小区所使用的序列组之间的互相关性是比较小的,从而减小了小区之间的干扰。或者,也可以将一个序列组分配给至少两个小区,例如分配给2个小区或3个小区等,而这至少两个小区需要是不相邻的小区,那么,即使至少两个小区使用的序列组是相同的序列组,因为至少两个小区不相邻,因此干扰也较小。其中,可以由网络设备通过动态方式为小区分配序列组,在不同的时刻,可能会为一个小区分配不同的序列组,且网络设备可以将分配给相应小区的序列组的信息通知给终端设备。一个序列组中可以包括至少一个序列,至少一个序列中不同的序列的长度可以是不同的,将一个序列组分配给一个小区之后,该小区可以根据实际需求,从该序列组中选择相应长度的序列使用,例如,一个小区在不同的时刻,可能会选择所分配的序列组中的不同长度的序列使用。另外,本文中所述的,第一序列集合中包括根据该种实施方式所得到的序列,可以是指,第一序列集合中包括根据该种实施方式所得到的序列中的全部或部分。
第一序列集合例如是预先配置给终端设备的,例如是由基站配置的,或者是由更高层的网元配置的,或者第一序列集合也可以是由协议规定的,具体的不做限制。
终端设备要根据序列{x(n)}生成第一信号,首先就要确定序列{x(n)},而序列{x(n)}是根据序列{s(n)}得到的,因此终端设备首先要确定序列{s(n)}。其中,终端设备可以从第一序列集合中选择一个序列作为序列{s(n)}。例如,终端设备可以根据第一移位寄存器序列的初始状态和第二移位寄存器序列的初始状态,从第一序列集合中选择一个序列作为序列{s(n)}。其中,第一移位寄存器序列的初始状态可以是固定序列,是终端设备已知的,而第二移位寄存器序列的初始状态,终端设备可以根据序列组的身份标识号(ID)或者根据终端设备所在的小区的ID来确定。其中,该序列组是网络设备为终端设备所在的小区所分配的序列组。
通过使用本申请实施例提供的第一序列集合中的序列生成的第一信号,可以在使用PUSCH或PUCCH或SRS发送第一信号时保持较好的频域平坦度,同时保持较低的PAPR值和较低的信号间互相关性,从而满足利用PUSCH或PUCCH或SRS发送信号的通信应用环境。
可选的,生成第一信号的过程,如图3所示,在具体实现中为:首先,终端设备对序列{x(n)}中的N个元素进行离散傅里叶变换(discrete fourier transform,DFT)处理,得到序列{f(n)}。这里主要指终端设备使用配置的序列{x(n)}中的N个元素进行DFT处理,得 到频域序列,这里的频域序列指序列{f(n)}。然后,终端设备将序列{f(n)}映射至N个子载波上,生成第一信号并发送给网络设备。
可选的,终端设备对包含N个元素的序列{x(n)}进行DFT处理得到频域序列,然后,将频域序列分别映射到N个子载波上得到第一信号的具体过程,如图3所示,包括:
S301、终端设备对包含N个元素的序列{x(n)}进行DFT处理,得到序列{f(n)}。
在S301,可选的,如图4a所示,终端设备对序列{x(n)}进行DFT处理得到序列{f(n)}的过程中,可以不使用滤波器。另外,终端设备对包含N个元素的序列{x(n)}进行DFT处理,除了序列{x(n)}外,终端设备所处理的序列还可以包括其他序列,可以理解为,终端设备是将序列{x(n)}和其他的至少一个序列进行拼接,得到新的序列,该新的序列的长度例如为M,终端设备再对M长的新的序列进行DFT,得到序列{f(n)}。例如参考图4b,为将序列{x(n)}和序列{Q(n)}进行拼接,得到新的序列,再对新的序列进行DFT的示意图。其中,图4b是以将序列{Q(n)}拆分为两部分,分别拼接在序列{x(n)}的头部和尾部为例,在实际应用中,也可以将序列{Q(n)}仅拼接在序列{x(n)}的头部或尾部。可以看到,由于图4b中序列{Q(n)}的长度为6,因此得到的序列{f(n)}的长度就是序列{x(n)}和序列{Q(n)}的长度之和,也就是N+6。当然,这里的序列{Q(n)}的长度为6只是一种示例,本申请实施例不限制序列{Q(n)}的长度。序列{Q(n)}承载的可以是数据,也可以是控制信息或其他信息。可选的,如图4c所示,终端设备对序列{x(n)}进行DFT处理得到序列{f(n)}的过程中,可以在使用滤波器之后,再进行DFT处理得到序列{f(n)}。可选的,如图4d所示,终端设备对序列{x(n)}进行DFT处理得到序列{f(n)}的过程中,可以在进行DFT处理之后,再使用滤波器得到序列{f(n)}。本申请实施例对于终端设备的处理方式不做限制。其中,使用滤波器有助于降低PAPR。
S302、终端设备将该序列{f(n)}分别映射至N个子载波上,得到N点的频域信号。
在具体实现中,N点的频域信号即包含N个元素的频域信号。
在下述本申请实施例公开的图5a和图5b中,s表示序列{f(n)}映射的N个子载波中的第一个子载波在通信系统中的子载波中的索引。
可选的,终端设备将序列{f(n)}中的N个元素分别映射至连续的N个子载波上。如图5a所示,可选的,序列{f(n)}中的元素f(0)到f(N-1)分别映射到N个连续的子载波,子载波标号为s+0,s+1,…,s+N-1。
在终端设备将序列{f(n)}中的N个元素分别映射至连续的N个子载波上的一种可能的示例中,终端设备将序列{f(n)}中的N个元素按照子载波从高到低的顺序,依次映射到连续的N个子载波上。其中,一个序列{f(n)}中元素映射到一个频域子载波。频域子载波是频域资源的最小单元,其用于承载数据信息。
在终端设备将序列{f(n)}中的N个元素分别映射至连续的N个子载波上的另一种可能的示例中,终端设备将序列{f(n)}中的N个元素按照子载波从低到高的顺序,依次映射到N个子载波上。将序列{f(n)}中一个元素映射到一个子载波就是在这个子载波上承载这个元素。映射之后,在该终端设备将数据通过射频发送时,相当于在这个子载波上发送这个元素。在通信系统中,不同的终端设备可以占用不同的子载波发送数据。N个子载波在通信系统中所存在的多个子载波中的位置可以是预定义或者网络设备通过信令配置的。
或者,终端设备也可以将序列{f(n)}中的N个元素分别映射至等间隔的N个子载波上。如图5b所示,以N个子载波之间的间隔是1为例,N个子载波在频域上是等间隔分布的。 序列{f(n)}中的元素f(0)到f(N-1)映射的子载波的间隔为1个子载波。具体为:分别映射到N个等间隔的子载波,子载波编号为s+0,s+2,…,s+2(N-1)。
S303、终端设备对包含N个元素的频域信号进行快速傅立叶逆变换(inverse fast Fourier transformation,IFFT),得到对应的时域信号,并为该时域信号添加循环前缀,生成第一信号。
需要说明的是,在本申请实施例中,生成第一信号的方式并不仅限于上述的终端设备对包含N个元素的序列{x(n)}进行DFT处理得到频域序列,然后,将频域序列分别映射至N个子载波上得到第一信号的实现方式。例如,终端设备还可以对序列{x(n)}使用成型滤波器得到序列{y(n)},然后将序列{y(n)}调制到载波上,得到第一信号。
S22、终端设备发送第一信号,网络设备接收来自终端设备的承载在N个子载波上的第一信号。
可选的,在执行S303时,终端设备将生成的N点的频域信号通过IFFT后得到的时域信号是一个正交频分复用(orthogonal frequency division multiplexing,OFDM)符号。在执行S303时,终端设备将第一信号通过射频发出去。也就是说,该终端设备在该N个子载波上发送承载序列{f(n)}的第一信号。
终端设备可以在一个OFDM符号上发送承载序列{f(n)}的第一信号。也可以在多个OFDM符号上发送承载序列{f(n)}的第一信号。
作为一种可选的方式,该第一信号可以为上行控制信息(uplink control information,UCI)、DMRS、探测参考信号(sounding reference signal,SRS)或控制信息。或者,第一信号还可以是确认应答(acknowledgment,ACK),或否定确认应答(negative acknowledgment,NACK),或者上行调度请求(scheduling request,SR)等。本申请实施例对于第一信号并不仅限于包括上述信息。
作为另一种可选的方式,第一信号为用于承载通信信息的信号。在具体实现中,该通信信息的承载方式可以是通过序列选择的方式承载,也可以是通过序列调制的方式承载,但不限于此。通信信息例如包括数据和/或控制信息。
其中,例如序列选择的方式为:为一个终端设备分配2 n个正交的序列。这2 n个正交的序列,例如是1个根序列的2 n个循环移位,这2 n个正交的序列能够承载n比特信息。例如,标号为0、1、2和3的4个序列。其中,00对应序列0,01对应序列1,10对应序列{2},11对应序列3,这样4个序列能够承载2比特信息。
例如序列调制的方式为:为一个终端设备分配1个序列,并且将该终端设备所需传输的信息生成调制符号。该调制符号包括但不限于BPSK符号,正交相移键控(quadrature phase shift keyin,QPSK)符号,8阶正交振幅调制(quadrature amplitude modulation,QAM)符号,16QAM符号等。将该调制符号与该序列相乘,生成实际的发送序列。例如,一个BPSK符合可能为1或者-1,对于一个序列{x(n)}而言,基于BPSK符号进行调制后,发送的序列就可以为{x(n)}或{-x(n)}。
在一种可能的示例中,如图2b对应说明书中的记载,终端设备在入网后,可以通过A和序列{b(n)}确定网络设备配置的包含N个元素的序列{x(n)}。需要说明的是,对于序列调制的方式,是通过序列{x(n)}中不同的A的取值,承载不同信息的。
例如,A可以为调制符号。此时,一路数据信息比特或者控制信息比特经过调制后,得到A。A承载在序列{x(n)}所包含的N个元素上,A不随着n的变化而改变。
或者,A为常数。例如A=1。例如,A可以是终端设备和网络设备都已知的符号。A也可以表示幅度。
需要说明的是,A是在一个发射时间单元上是常数,不代表A是固定不变的,在不同的时刻发送第一信号时,A可以是变的。例如,序列{x(n)}中包含的全部N个元素是参考信号,A是参考信号的幅度,终端设备在第一次发送第一信号时,可以按A=1发送。终端设备在第二次发送第一信号时,可以按A=2发送。
网络设备按照预定义或者预先配置的N个子载波在通信系统的子载波中的位置接收N个子载波上的信号。
例如,网络设备可以在连续的N个子载波上获取N个子载波上的第一信号,或者,在等间隔的N个子载波上获取N个子载波上的第一信号。
S23、网络设备获取第一信号承载的序列{x(n)}中的N个元素。
例如,获取序列{x(n)}中的N个元素的方式为,网络设备获取序列{f(n)}中的N个元素,对该序列{f(n)}进行离散傅里叶逆变换处理(inverse discrete fourier transformation,IDFT),得到序列{x(n)}中的N个元素。
根据前文的记载可知,该第一信号是由终端设备对序列{x(n)}中的N个元素进行DFT处理,得到序列{f(n)},再将该序列{f(n)}映射至N个子载波上生成的。该序列{x(n)}的具体说明可以参见前文,这里不再进行赘述。
那么,网络设备在连续的N个子载波上获取N个子载波上的第一信号,或者,在等间隔的N个子载波上获取所述N个子载波上的第一信号,去除第一信号的循环前缀,得到时域信号,对时域信号进行M点的DFT,得到包含N个元素的频域信号,该M大于等于N,然后,基于包含N个元素的频域信号,确定序列{f(n)}中的N个元素。
在具体实现中,终端设备在入网后,使用配置的序列{x(n)}发送PUSCH或PUCCH或SRS,而网络设备使用配置给终端设备的序列{x(n)}接收PUSCH或PUCCH或SRS。
S24、网络设备根据序列{x(n)}中的N个元素对第一信号进行处理。
可选的,网络设备对第一信号的处理过程示意图,如图6a所示,网络设备将获取的序列{y(n)}与所有可能的序列{x′(n)}分别相关处理并进行最大似然比较,获取终端设备传输的数据。其中,序列{y(n)}是网络设备根据接收的第一信号得到的,可参考图6b,网络设备将接收的第一信号去掉循环前缀,再进行快速傅立叶变换(fast Fourier transformation,FFT),和解映射等处理,得到序列{y(n)}。{x′(n)}是由{x(n)}生成的本地序列。结合前文的介绍,例如对于两比特信息,取值组合为{(0,0),(0,1),(1,0),(1,1)}。结合图2b,当两比特信息为(0,0)时,得到的序列x′(n)是序列x′ 1(n),当两比特信息为(0,1)时,得到的序列x′(n)是序列x′ 2(n),当两比特信息为(1,0)时,得到的序列x′(n)是序列x′ 3(n),当两比特信息为(1,1)时,得到的序列x′(n)是序列x′ 4(n)。所述的4个序列x′ 1(n),x′ 2(n),x′ 3(n),x′ 4(n),可以是同一个序列的循环移位序列,将序列{y(n)}与x′ 1(n),x′ 2(n),x′ 3(n),x′ 4(n)分别相关,得到4个相关值。在最大相关值对应的两比特信息的取值即为网络设备获取的数据。例如,最大相关值是序列{y(n)}与x′ 1(n)相关得到的,则两比特信息是(0,0)。
通过使用本申请实施例提供的新的序列,可以在使用PUSCH或PUCCH或SRS发送信号时保持较好的频域平坦度,同时保持较低的PAPR值和较低的信号间互相关性,从而满足利用PUSCH或PUCCH或SRS发送信号的通信应用环境。
为了解决同样的技术问题,下面通过另一个实施例提供第二种信号发送、接收方法。 其中,该方法所涉及的流程可参考图2a所示的实施例中的S21~S24,以及S301~S303。与图2a所示的实施例不同的是,在第二种信号发送、接收方法中,第一序列集合中包括的序列的生成方式可以是不同的。
作为第一序列集合的第二种实施方式,第一序列集合包括序列{k(n)},元素k(n)满足k(n)=c((n+t)mod 1023),n=0,1,2,…,N-1,t为整数,t可以看做是一个循环移位,关于t的介绍可参考第一序列集合的第一种实施方式中的相关介绍。Mod表示取模运算,因为c(n)是一个长度为1023的序列,因此如果序列{k(n)}的长度大于1023,就需要对序列{c(n)}进行扩充,例如在取序列{c(n)}的第1023个元素之后,再将序列{c(n)}的第一个元素拼接到后面作为第1024个元素,从而通过对序列{c(n)}进行循环扩充来得到序列{k(n)}。
元素c(n)满足c(n)=(c 1(n)+c 2((n+v)mod 31))mod 2,n=0,1,2,…,1022,v为整数,c 1(n)为序列{c 1(n)}中的元素,c 2(n)为序列{c 2(n)}中的元素,序列{c 1(n)}是第一移位寄存器序列,序列{c 2(n)}是第二移位寄存器序列,第一移位寄存器序列的迭代公式为
Figure PCTCN2019102892-appb-000032
也就是元素c 1(n)满足该公式,第二移位寄存器序列的迭代公式为
Figure PCTCN2019102892-appb-000033
也就是元素c 2(n)满足该公式。v是整数。
{c 1(n),n=0,1,2,3,4,5,6,7,8,9}是第一移位寄存器序列的初始状态,{c 2(n),n=0,1,2,3,4}是第二移位寄存器序列的初始状态。
本实施例中所述的第一移位寄存器序列,与图2a所示的实施例中所述的第一移位寄存器序列,可以是不同的移位寄存器序列,本实施例中所述的第二移位寄存器序列,与图2a所示的实施例中所述的第二移位寄存器序列,可以是不同的移位寄存器序列。
在第一序列集合的第二种实施方式下,N满足768≤N≤1620,例如N的取值可以是768、810、864、900、960、972、1080、1152、1200、1296、1350、1440、1458、1500或1536,其中,N可以取768、810、864、900、960、972、1080、1152、1200、1296、1350、1440、1458、1500或1536中的任意一个,或者,N可以取768、810、864、900、960、972、1080、1152、1200、1296、1350、1440、1458、1500或1536中的一部分值,例如N可以取768、810、864、900、960、972、1080或1152,也就是说,对于768≤N≤1620这个范围,其中包括的每个取值都可以作为N的值,或者,也可以是其中包括的部分取值可以作为N的值,具体的不做限制。[q 0,q 1,q 2,q 3,q 4,q 5,q 6,q 7,q 8,q 9]和[w 0,w 1,w 2,w 3,w 4]分别为

或者,除了以上列举的取值之外,[q 0,q 1,q 2,q 3,q 4,q 5,q 6,q 7,q 8,q 9]和[w 0,w 1,w 2,w 3,w 4]还可以有其他取值,具体的不做限制。
上述方式所得的序列{c(n)}是最小码距为496的循环码,即{c(n)}的互相关性和自相关性比较好,因此可以保证第一序列集合中的不同序列间的互相关性比较低,根据第一序列集合中的序列得到的第一信号的频域平坦度比较好。同时上述方式所得到的序列是个数可以满足系统需求,至少30个互相关比较低的序列,同时个数较少的序列。
在第一序列集合的第二种实施方式中,第一序列集合中包括的序列{k(n)}也是通过两个移位寄存器序列得到的。在本申请实施例中,也可以令第一移位寄存器序列的级数大于第二移位寄存器序列的级数,例如第一移位寄存器序列的级数为10,第二移位寄存器序列的级数为5。通过这样的机制生成的序列,当第一移位寄存器序列初始状态相同时,如果两个序列对应的第二移位寄存器序列的初始状态不同,则这两个序列的互相关性就比较小,或者可以认为,这两个序列是基于不同的根序列生成的。
因此,本申请实施例提出,如果第一序列集合中包括根据第一序列集合的第二种实施方式所得到的序列,则,可以将第一序列集合包括的序列进行分组。在分组时,可以根据第二移位寄存器序列的初始状态来划分,例如,v的取值是固定的,则可以根据第一移位寄存器序列的初始状态和第二移位寄存器序列的初始状态来划分,关于这种分组方式,可参考图2a所示的实施例中的相关介绍。或者,在分组时,也可以根据第一移位寄存器序列的初始状态、第二移位寄存器序列的初始状态、以及v的取值来划分,例如,第一移位寄存器序列的初始状态和第二移位寄存器序列的初始状态都是已知的,例如均为固定序列,v的取值可以根据序列组ID或小区ID确定。例如,第一移位寄存器序列的初始状态和第二移位寄存器序列的初始状态都是固定的,v的取值{v 1,v 2}使得v 1≠v 2(mod31),这样通过不同的v的取值就可以确定两个不同的序列(组),v的取值可以根据序列组ID确定或者根据小区ID确定。通过这种方式划分得到的至少一个序列组,同样满足不同的序列组之间的互相关性较小。在得到至少一个序列组后,如何为小区分配序列组,可参考图2a所示的实施例中的相关介绍。
另外,关于本实施例的其他相关内容,例如终端设备如何生成第一信号、如何发送第一信号、及网络设备如何接收和处理第一信号等过程,均可参考图2a所示的实施例中的相关介绍,不多赘述。其中,图2a所示的实施例中,可以认为包括了图3所示的内容。
为了解决同样的技术问题,下面通过再一个实施例提供第三种信号发送、接收方法。其中,该方法所涉及的流程可参考图2a所示的实施例中的S21~S24,以及S301~S303。与如上的两个实施例均不同的是,在第三种信号发送、接收方法中,第一序列集合中包括的 序列的生成方式是不同的。
作为第一序列集合的第三种实施方式,第一序列集合中包括的序列是由一个移位寄存器序列。
具体的,在第一序列集合的第三种实施方式下,第一序列集合包括序列{k(n)},元素k(n)满足k(n)=c((n+t)mod 254),n=0,1,2,…,N-1。

其中,序列{c 1(n)}可以是第三移位寄存器序列,c 1(n)∈{0,1,2,3},可以理解为,c 1(n)是一个四元序列,也就是可以有4种取值,c 1(n)∈{0,1,2,3}。第三移位寄存器序列的迭代公式为
Figure PCTCN2019102892-appb-000035
Figure PCTCN2019102892-appb-000036
也就是元素c 1(n)满足该公式。或者,第三移位寄存器序列的迭代公式为c 1(n)=(c 2(n)+2×c 3(n+v)mod254)mod 4,n=0,1,2,...246,v为整数,也就是元素c 1(n)也可以满足该公式。c 2(n)∈{0,1,2,3},c 3(n)∈{0,1},c 2(n)是序列{c 2(n)}中的元素,c 3(n)是序列{c 3(n)}中的元素,序列{c 2(n)}是第一移位寄存器序列,第一移位寄存器序列的迭代公式为
Figure PCTCN2019102892-appb-000037
也就是元素c 2(n)满足该公式。序列{c 3(n)}是第二移位寄存器序列,第一移位寄存器序列的迭代公式为
Figure PCTCN2019102892-appb-000038
也就是元素c 3(n)满足该公式。
本实施例中所述的第一移位寄存器序列,与前述的实施例中所述的第一移位寄存器序列,可以是不同的移位寄存器序列,本实施例中所述的第二移位寄存器序列,与前述的中所述的第二移位寄存器序列,可以是不同的移位寄存器序列。
在第一序列集合的第三种实施方式下,N满足192≤N≤432,例如N的取值可以是192、216、240、270、288、300、324、360、384或432,其中,N可以取192、216、240、270、288、300、324、360、384或432中的任意一个,或者,N可以取192、216、240、270、288、300、324、360、384或432中的一部分值,例如N可以取300、324、360、384或432,也就是说,对于192≤N≤432这个范围,其中包括的每个取值都可以作为N的值,或者,也可以是其中包括的部分取值可以作为N的值,具体的不做限制。[y 0,y 1,y 2,y 3,y 4,y 5,y 6]可以为[3,1,0,0,2,0,0]、[3,0,2,0,3,0,0]、[3,0,0,1,0,2,0]、[3,3,1,1,2,2,0]、[3,2,1,3,3,2,0]、[3,2,3,2,2,1,1]、[3,2,1,1,3,1,1]、[3,3,1,1,2,3,1]、[3,3,1,2,3,3,1]、[3,0,2,2,3,3,1]、[3,3,3,2,2,1,2]、[3,1,2,3,0,3,2]、[3,0,2,1,1,3,2]、[3,3,3,1,3,3,2]、[3,0,0,2,0,0,3]、[3,2,1,0,1,2,3]、[3,1,2,2,1,2,3]、或[3,1,2,3,2,2,3]。或者[y 0,y 1,y 2,y 3,y 4,y 5,y 6]也可以有其他取值,具体的不做限制。
上述方式所得的序列{c(n)}是最小码距为118的循环码,即{c(n)}的互相关性和自相关性比较好,因此可以保证第一序列集合中的不同序列间的互相关性比较低,根据第一序列集合中的序列得到的第一信号的频域平坦度比较好。同时上述方式所得到的序列是个数可以满足系统需求,至少30个互相关比较低的序列,同时个数较少的序列。
如果第一序列集合包括根据第一序列集合的第三种实施方式所得到的序列,也可以对第一序列集合包括的序列进行分组,例如第一序列集合可以包括至少两个序列组,其中的每个序列组可以包括至少一个序列,当然,不同的序列组所包括的序列的数量可以相同, 也可以不同。在分组时,也可以使得划分的任意两个序列组之间的序列的互相关性都较小,例如任意两个序列组之间的序列的互相关性小于阈值。那么,同样可以将每个序列组分配给一个小区,或者说,一个序列组仅分配给一个小区,也就是,一个序列组不会分配给多个小区,这样,不同的小区所使用的序列组之间的互相关性是比较小的,从而减小了小区之间的干扰。或者,也可以将一个序列组分配给至少两个小区,例如分配给2个小区或3个小区等,而这至少两个小区需要是不相邻的小区,那么,即使至少两个小区使用的序列组是相同的序列组,因为至少两个小区不相邻,因此干扰也较小。其中,可以由网络设备通过动态方式为小区分配序列组,在不同的时刻,可能会为一个小区分配不同的序列组,且网络设备可以将分配给相应小区的序列组的信息通知给终端设备。一个序列组中可以包括至少一个序列,至少一个序列中不同的序列的长度可以是不同的,将一个序列组分配给一个小区之后,该小区可以根据实际需求,从该序列组中选择相应长度的序列使用,例如,一个小区在不同的时刻,可能会选择所分配的序列组中的不同长度的序列使用。
在本申请实施例中,对于如上三个实施例所介绍的第一序列集合的三种实施方式来说,这三种实施方式中的全部实施方式或者部分实施方式可以是并存的,也就是如上的三个实施例可以全部结合应用,或者其中任意两个实施例可以结合应用,例如第一序列集合中可以包括根据如上的三种实施方式所得到的序列,或者第一序列集合中可以包括根据如上的第一种实施方式和第二种实施方式所得到的序列,或者第一序列集合中可以包括根据如上的第一种实施方式和第三种实施方式所得到的序列,或者第一序列集合中可以包括根据如上的第二种实施方式和第三种实施方式所得到的序列;或者,第一序列集合的如上三种实施方式也可以是分别应用的,也就是这三种实施方式不共存,或者说,如上的三个实施例需单独应用,例如,第一序列集合中可以包括根据如上的第一种实施方式所得到的序列,或者第一序列集合中可以包括根据如上的第二种实施方式所得到的序列,或者第一序列集合中可以包括根据如上的第三种实施方式所得到的序列。其中,本文中所述的,第一序列集合中包括根据第一种实施方式所得到的序列,可以是指,第一序列集合中包括根据第一种实施方式所得到的序列中的全部或部分,同理,本文中所述的,第一序列集合中包括根据第二种实施方式所得到的序列,可以是指,第一序列集合中包括根据第二种实施方式所得到的序列中的全部或部分,以及,第一序列集合中包括根据第三种实施方式所得到的序列,可以是指,第一序列集合中包括根据第三种实施方式所得到的序列中的全部或部分。
具体的,第一序列集合中究竟包括哪些序列,本申请实施例不做限制。
而如果第一序列集合中包括根据第一序列集合的第三种实施方式所得到的序列,则终端设备也可以根据相应的方法来从第一序列集合中选择序列{s(n)},对于具体的选择方式不做限制。
关于本实施例的其他相关内容,例如终端设备如何生成第一信号、如何发送第一信号、及网络设备如何接收和处理第一信号等过程,均可参考图2a所示的实施例中的相关介绍,不多赘述。
总之,通过使用本申请实施例提供的新的序列,可以在使用PUSCH或PUCCH或SRS发送信号时保持较好的频域平坦度,同时保持较低的PAPR值和较低的信号间互相关性,从而满足利用PUSCH或PUCCH或SRS发送信号的通信应用环境,减小小区之间的干扰。
