Description

信息指示方法及装置、系统 技术领域
本发明实施例涉及通信领域,具体而言,涉及一种信息指示方法及装置、系统。
背景技术
长期演进(Long-Term Evolution,简称为LTE)系统、高级长期演进系统(Long-Term Evolution Advance,简称为LTE-Advance)系统、IMT-Advanced(International Mobile Telecommunication Advanced)高级的国际移动通信系统都是以OFDM(Orthogonal Frequency Division Multiplexing,正交频分复用)技术为基础,在OFDM系统中主要是时频两维的数据形式,在LTE、LTE-A中RB(Resource Block,资源块;资源块映射在物理资源上则称为Physical Resource Block,物理资源块)定义为在时间域上连续1个slot(时隙)内的OFDM符号,在频率域上连续12或24个子载波,所以1个RB由
Figure PCTCN2017092931-appb-000001
个RE(Resource Element,资源单元),其中Nsymb表示1个slot内的OFDM符号的个数,
Figure PCTCN2017092931-appb-000002
表示资源块在频率域上连续子载波的个数。
LTE系统、LTE-A系统中子帧类型主要分为用于点对点传输的单播子帧和点对多点传输的多播子帧(每个子帧共2个时隙)。循环前缀类型主要分为normal CP(normal Cyclic Prefix,正常循环前缀),此时每个子帧共14个OFDM符号,extended CP(extended Cyclic Prefix,扩展循环前缀),此时每个子帧共12个OFDM符号,其中OFDM符号序号从“0”开始编号,如“#0”表示第1个OFDM符号。
在相关技术中,上行数据如果传输失败,则上行数据重传采用的是上行同步HARQ(Hybrid Automatic Repeat Request,混合自动重传请求)传输,同步HARQ意味着重传子帧位置是收发两端事先约定好的,即每个HARQ process对应着不同的重传子帧位置,也就是说或HARQ process、 重传子帧位置均无需信令通知。此外,相关技术的通信系统中,通知发射端发射的上行数据是否被接收端接收正确的方式有两种:一是通过PHICH(Physical Hybrid-ARQ Indicator Channel,物理HARQ指示信道)指示,二是通过UL grant(UpLink grant,上行链路授权信息)指示。具体地,PHICH仅传输1bit或是2bits的DL ACK/NACK(DownLink Acknowledge/Nacknowledge,下行链路确认/非确认信息),即如果传输ACK则表明对应的上行数据接收正确,如果传输NACK则表明对应的上行数据接收错误,需要进行非自适应重传,其中非自适应重传表示重传时资源分配、编码调制等级等信息和首传相同。具体地,UL grant不仅传输NDI(New data indicator,新数据指示),也传输资源分配、编码调制等级等信息,即如果NDI与对应HARQ process的前一次传输相比发生了翻转,则表明对应的上行数据传输是新传,如果NDI与对应HARQ process的前一次传输相比没有翻转,则表明对应的上行数据传输是自适应重传,其中自适应重传表示重传时资源分配、编码调制等级等信息和之前的传输不同。
在相关技术的NR(New Radio)系统(或称为5G系统)中,有如下几个典型的特点:时间方向上调度颗粒度是非常灵活的;在较高的载波频率上通常使用数字、模拟、数字加模拟混合波束(或称为基带、射频、基带加射频混合波束)的传输方式来提高覆盖范围,为了降低时延引入UL self-contained反馈的结构。基于上述NR系统中的特点,如果继续沿用LTE、LTE-A系统中的上行同步HARQ传输,同步HARQ传输将会限制时间颗粒度的灵活性,不适合NR灵活的帧结构;不考虑终端地理、空间分布的码分方式下PHICH的传输不适合数字、模拟、数字加模拟混合波束传输;如果应用UL self-contained方式,过多的PHICH势必增加了GP(保护间隔)的开销。
针对相关技术中存在的上述问题,目前尚未发现有效的解决方案。

发射端:
新传时,新传的上行数据对应的HARQ process采用同步的方式,即某一特定子帧对应某一特定HARQ process number,也即新传的上行数据对应的HARQ process number没有显示的比特指示;
重传时,重传的上行数据对应的HARQ process采用异步的方式,以具体数值进行说明:P=3;使用P=3bits用于指示HARQ process number。
接收端:
根据NDI与对应HARQ process的前一次传输相比是否发生了翻转,如果翻转了,则表明对应的上行数据传输是新传,则新传的上行数据对应的UL grant的信息字段物理含义为第一物理含义,根据某一特定子帧位置判断此时的HARQ process number;
如果没有翻转,则表明对应的上行数据传输是重传,则重传的上行数 据对应的UL grant的部分信息资源物理含义为第二物理含义;根据3bits判断此时的HARQ process number。
具体实施例2
上行数据对应的新传或重传指示信息通过UL grant的部分信息字段承载,具体地,假设HARQ process number通过重用UL grant的部分信息字段。新传的上行数据对应的UL grant的信息字段物理含义为第一物理含义,新传的上行数据对应的HARQ process采用同步的方式。重传的上行数据对应的UL grant的部分信息资源物理含义为第二物理含义,重传的上行数据对应的HARQ process采用异步的方式,优选地,重传时,原有RA信息字段对应比特数为X bits,原有MCSRV信息字段对应比特数为Y bits,使用X bits中的M bits和/或Y bits中的N bits用于指示UL HARQ process number和非自适应重传、半自适应重传,其中M、N是大于等于0的整数。
发射端:
新传时,新传的上行数据对应的HARQ process采用同步的方式,即某一特定子帧对应某一特定HARQ process number,也即新传的上行数据对应的HARQ process number没有显示的比特指示;
重传时,重传的上行数据对应的HARQ process采用异步的方式,以具体数值进行说明:X=10,Y=5,M=4,N=0,假设使用M+N=4bits用于指示HARQ process number和非自适应重传、半自适应重传;使用1bit用于指示非自适应重传、半自适应重传;使用M+N-1=3bits用于指示HARQ process number;
非自适应重传时,重传时资源分配、编码调制等级等信息与新传或与上一次传输相同,此时X-M=6bits、Y-N=5bits的功能用于后续通信系统版本中扩展使用;
半自适应重传时,本次重传是在新传或上一次传输的RA基础上增加或减少2^(X-M)=2^6个资源块;
半自适应重传时,本次重传根据2^(Y-N)=2^5直接调整到对应的MCS等级、RV版本。
接收端:
根据NDI与对应HARQ process的前一次传输相比是否发生了翻转,如果翻转了,则表明对应的上行数据传输是新传,则新传的上行数据对应的UL grant的信息字段物理含义为第一物理含义,根据某一特定子帧位置判断此时的HARQ process number;
如果没有翻转,则表明对应的上行数据传输是重传,则重传的上行数据对应的UL grant的部分信息资源物理含义为第二物理含义;根据1bit判断此时是非自适应重传、半自适应重传;根据3bits判断此时的HARQ process number。
具体实施例3
上行数据对应的新传或重传指示信息通过UL grant的部分信息字段承载,具体地,假设HARQ process number通过额外信息字段指示。新传的上行数据对应的UL grant的信息字段物理含义为第一物理含义,新传的上行数据对应的HARQ process采用异步的方式。重传的上行数据对应的UL grant的部分信息资源物理含义为第二物理含义,重传的上行数据对应的HARQ process采用异步的方式,优选地,重传时,原有RA信息字段对应比特数为X bits,原有MCSRV信息字段对应比特数为Y bits,使用X bits中的M bits和/或Y bits中的N bits用于指示自适应重传、非自适应重传、半自适应重传,其中M、N是大于等于0的整数。
发射端:
以具体数值进行说明:X=10,Y=5,M=2,N=0,假设使用M+N=2bits用于指示自适应重传、非自适应重传、半自适应重传;使用2bits用于指示自适应重传、非自适应重传、半自适应重传;
自适应重传时,重传时资源分配、编码调制等级等信息与新传或与上一次传输可以不同,此时X-M=8bits、Y-N=5bits的功能用于自适应重传;
非自适应重传时,重传时资源分配、编码调制等级等信息与新传或与上一次传输相同,此时X-M=5bits、Y-N=5bits的功能用于后续通信系统版本中扩展使用;

半自适应重传时,本次重传根据2^(Y-N)=2^5直接调整到对应的MCS等级、RV版本。
接收端:
根据NDI与对应HARQ process的前一次传输相比是否发生了翻转,如果翻转了,则表明对应的上行数据传输是新传,则新传的上行数据对应的UL grant的信息字段物理含义为第一物理含义,根据HARQ process对应的额外信息字段判断此时的HARQ process number;
如果没有翻转,则表明对应的上行数据传输是重传,则重传的上行数据对应的UL grant的部分信息资源物理含义为第二物理含义;根据HARQ process对应的额外信息字段判断此时的HARQ process number;根据2bits判断此时是自适应重传、非自适应重传、半自适应重传。
该实施例也可以使用M=1,即发射端使用1bit用于指示非自适应重传、半自适应重传,接收端根据1bit判断此时是非自适应重传、半自适应重传,具体不再累述。
具体实施例4
上行数据对应的新传或重传指示信息通过UL grant的部分信息字段承载,具体地,假设UL grant中不包括HARQ process number。新传的上行数据对应的UL grant的信息字段物理含义为第一物理含义,新传的上行数据对应的HARQ process采用同步的方式。重传的上行数据对应的UL grant的部分信息资源物理含义为第二物理含义,重传的上行数据对应的HARQ process采用同步的方式,优选地,重传时,原有RA信息字段对应比特数为X bits,原有MCSRV信息字段对应比特数为Y bits,使用X bits 中的M bits和/或Y bits中的N bits用于指示自适应重传、非自适应重传、半自适应重传,其中M、N是大于等于0的整数。
发射端:
以具体数值进行说明:X=10,Y=5,M=2,N=0,假设使用M+N=2bits用于指示自适应重传、非自适应重传、半自适应重传;使用2bits用于指示自适应重传、非自适应重传、半自适应重传;
自适应重传时,重传时资源分配、编码调制等级等信息与新传或与上一次传输可以不同,此时X-M=8bits、Y-N=5bits的功能用于自适应重传;
非自适应重传时,重传时资源分配、编码调制等级等信息与新传或与上一次传输相同,此时X-M=5bits、Y-N=5bits的功能用于后续通信系统版本中扩展使用;
半自适应重传时,本次重传是在新传或上一次传输的RA基础上增加或减少2^(X-M)=2^5个资源块;
半自适应重传时,本次重传根据2^(Y-N)=2^5直接调整到对应的MCS等级、RV版本。
接收端:
根据NDI与对应HARQ process的前一次传输相比是否发生了翻转,如果翻转了,则表明对应的上行数据传输是新传,则新传的上行数据对应的UL grant的信息字段物理含义为第一物理含义,根据某一特定子帧位置判断此时的HARQ process number;
如果没有翻转,则表明对应的上行数据传输是重传,则重传的上行数据对应的UL grant的部分信息资源物理含义为第二物理含义;根据某一特定子帧位置判断此时的HARQ process number;根据2bits判断此时是自适应重传、非自适应重传、半自适应重传。
该实施例也可以使用M=1,即发射端使用1bit用于指示非自适应重传、半自适应重传,接收端根据1bit判断此时是非自适应重传、半自适 应重传,具体不再累述。
