Description
本申请要求在2017年1月4日提交中国专利局、申请号为201710005602.X、申请名称为“一种混合自动重传请求HARQ传输方法及相关设备”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。
本申请涉及通信技术领域,尤其涉及一种混合自动重传请求HARQ的传输方法及相关设备。
1、numerology介绍
Numerology,基带参数,是3GPP(3
rd Generation Partnership Project,第三代合作伙伴)无线物理层中的一个术语。不同的Numerology支持的子载波间隔不同。
2、TTI介绍
TTI(Transmission Time Interval,传输时间间隔),传统的LTE(Long Term evolution,长期演进)的系统中,TTI长度为1ms。从LTE R14开始,为了支持时延缩减,引入了不同TTI长度,如:1个OFDM(Orthogonal Frequency Division Multiplexing,正交频分复用)符号长度。
目前,在LTE系统中,一方面,不管是单小区工作模式还是CA(Carrier Aggregation,载波聚合)工作模式,终端只支持一种numerology;另一方面,LTE系统虽然支持TTI长度可变,但是TTI变化是半静态的,即一段时间内使用的TTI长度是固定的。
因此,针对LTE系统中的HARQ传输方案,对于单小区工作模式来说,一个HARQ实体对应的numerology/TTI相同;对于CA工作模式来说,CA下每个小区的HARQ实体所对应的numerology/TTI也相同。那么,相较于LTE 系统,5G系统是一个多numerology和/或多TTI共存的系统,而对于多numerology和/或多TTI共存的系统,现有技术中尚不存在一种针对该类型系统的HARQ传输方案。

为了使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请作进一步地详细描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例,都属于本申请保护的范围。
在本申请的背景技术部分介绍了numerology和TTI,下面简单介绍LTE 系统的HARQ传输方案,具体的:
1、单小区工作模式。
对于下行,支持异步HARQ。一个小区维护一个HARQ实体,一个HARQ entity维护一组并行的下行HARQ进程。每个HARQ进程对应一个进程号。物理层调度基于HARQ进程进行调度,HARQ进程号携带在物理层下行调度信令中。
对于上行,支持同步HARQ。一个小区维护一个HARQ实体,一个HARQ实体维护一组并行的上行HARQ进程。每个HARQ进程对应一个HARQ进程号。物理层调度同样基于HARQ进程进行调度,但是由于LTE系统上行是同步HARQ,所以物理层上行调度信令中不需要携带HARQ process ID。
且在LTE系统中HARQ相关的RRC(Radio Resource Control,无线资源控制)层配置参数只有一个,即maxHARQ-Tx,该参数的含义是上行HARQ最大传输次数。
2、CA
终端可以同时聚合多个小区的物理资源进行数据和/或控制信息的传输。对于CA系统,CA下每个小区的HARQ传输方法和上面提到的单小区的HARQ传输方法一致。一个HARQ entity对应的numerology/TTI都不变。
因此,基于上述LTE系统下的HARQ传输方案可知,LTE系统中HARQ实体对应的numerology/TTI都不变,且配置参数只有一个maxHARQ-Tx。显然,LTE系统中HARQ传输方案不能适用于支持多numerology和/或多TTI的5G系统,为了弥补这样的缺陷,本申请实施例提供一种混合自动重传请求HARQ的传输方法。
如图1所示,为本申请实施例提供的一种混合自动重传请求HARQ的传输方法,包括如下步骤:
步骤101:终端基于小区维护一个HARQ实体,所述HARQ实体支持多个并行HARQ进程;
步骤102:所述终端接收由网络侧设备发送的调度信令;
步骤103:所述终端根据所述调度信令,确定所述调度信令针对的所述HARQ实体的HARQ进程号及与所述HARQ进程号对应的基带参数和/或传输时间间隔。
本申请实施例提供的一种混合自动重传请求HARQ的传输方法既可以为上行HARQ的传输方法,也可以为下行HARQ的传输方法,在本申请实施例中不作具体限定。而在后续描述过程中,均以上行HARQ传输为例进行说明。
在本申请实施例中,首先执行步骤步骤101:终端基于小区维护一个HARQ实体,所述HARQ实体支持多个并行HARQ进程。
在具体实现过程中,终端基于小区维护一个HARQ实体,一个HARQ实体支持多个并行HARQ进程,多个并行HARQ进程中每个进程对应的基带参数和/或TTI可以相同或者不同,同一个HARQ进程初传和重传对应的基带参数和/或TTI也可以相同或者不同。
在本申请实施例中,在终端接收由网络侧设备发送的调度信令之前,所述方法还包括:
所述终端接收由所述网络侧设备发送的与所述终端对应的HARQ配置信息;
其中,所述HARQ配置信息包括以下任意一种或多种的组合:
最大上行/下行HARQ传输次数;
调度定时关系;
HARQ定时关系;
非连续接收DRX定时器相关配置信息。
进一步,在本申请实施例中,所述HARQ配置信息是由所述网络侧设备基于每个终端配置的一套参数;或,
所述HARQ配置信息是由所述网络侧设备基于每个基带参数和/或传输时间间隔配置的一套参数。
在本申请实施例中,最大上行/下行HARQ传输次数表明一个HARQ进程对应的数据的最大发送次数,在超出最大上行/下行HARQ传输次数后,则 放弃重传。
在本申请实施例中,调度定时关系为接收到网络侧设备发送的调度信令到对应的数据传输时刻之间的时间间隔。
HARQ定时关系为数据传输时刻和与该数据对应的HARQ反馈之间的时间间隔。
非连续接收DRX定时相关配置信息包括但不限于HARQ RTT timer(HARQ回程时间定时器)、drx-inactivity timer(DRX持续时间定时器)、drx-retransmission timer(DRX重传定时器)。
在本申请实施例中,在初传调度信令为上行调度信令时,终端接收由网络侧设备发送的包括最大上行HARQ传输次数、调度定时关系、HARQ定时关系及非连续接收DRX定时器相关配置信息HARQ配置信息;在初传调度信令为下行调度信令时,终端接收由网络侧设备发送的包括调度定时关系、HARQ定时关系及非连续接收DRX定时器相关配置信息的HARQ配置信息。
在本申请实施例中,HARQ配置信息可以是由网络侧设备基于每个终端配置的一套参数,即对不同的基带参数和/或TTI对应相同的HARQ配置参数。
在本申请实施例中,HARQ配置信息也可以是网络侧设备基于每个基带参数和/或TTI配置的一套参数,在该实现方式中,无论是初传还是重传都是根据该进程对应的基带参数和/或TTI配置确定对应的HARQ配置信息。下面分别进行描述。
在本申请实施例中,若初传和重传使用的基带参数和/或传输时间间隔不同;
所述最大上行和/或下行HARQ传输次数由与所述初传对应的第一基带参数和/或第一传输时间间隔确定的次数;或
所述最大上行和/或下行HARQ传输次数为由与所述重传对应的第二基带参数和/或第二传输时间间隔确定的次数。
在具体实现过程中,若重传和初传使用的基带参数和/或TTI相同,最大上行和/下行HARQ传输次数则为网络侧设备基于初传时的第一基带参数和/ 或第一传输时间间隔确定的次数。
若重传和初传时使用的基带参数和/或传输时间间隔不同,最大上行和/或下行HARQ传输次数则为网络侧设备根据与初传对应的第一基带参数和/或第一传输时间间隔确定的次数;或者为网络侧设备根据与重传对应的第二基带参数和/或第二传输时间间隔确定的次数。
在本申请实施例中,若初传和重传使用的基带参数和/或传输时间间隔不同,所述最大上行和/或下行HARQ传输次数由所述网络侧设备根据协议约定或网络侧设置确定由与所述初传对应的第一基带参数和/或第一传输时间间隔确定还是由与所述重传对应的第二基带参数和/或第二传输时间间隔确定。
在具体实现过程中,若初传和重传使用的基带参数和/或传输时间间隔不同,最大上行/下行HARQ传输次数则是由网络侧设备根据协议约定或由网络侧设置确定是采用根据第一基带参数和/或第一传输时间间隔确定还是根据第二基带参数和/或第二传输时间间隔确定。
在接收由网络侧设备发送的与终端对应的HARQ配置信息之后,则执行步骤102:所述终端接收由网络侧设备发送的调度信令。
在本申请实施例中,终端接收由网络侧设备发送的调度信令可以为初传调度信令,也可以为重传调度信令,下面分别对这两种情况进行描述。
第一种:
所述终端接收由所述网络侧设备发送的初传调度信令;

所述终端根据所述初传调度信令,确定所述初传调度信令针对的HARQ实体的HARQ进程号及与所述HARQ进程号对应第一基带参数和/或第一传输时间间隔。
在具体实现过程中,终端接收到由网络侧设备发送的初传调度信令后,则根据初传调度信令确定所述调度信令针对的HARQ实体的HARQ进程号及 与HARQ进程号对应的第一基带参数和/或第一传输时间间隔。
进一步,在本申请实施例中,终端根据初传调度信令确定第一基带参数和/或传输时间间隔的方式包括但不限于以下两种实现方式,这两种实现方式具体为:
所述终端根据所述初传调度信令中携带的HARQ进程号对应的第一基带参数和/或第一传输时间间隔确定所述第一基带参数和/或所述第一传输时间间隔;或,
所述终端根据所述初传调度信令中携带的HARQ进程号对应的第一传输时间间隔确定所述第一传输时间间隔;根据所述初传调度信令中携带的资源指示信息,以及资源和基带参数的映射信息确定所述第一基带参数。
在具体实现过程中,若初传调度信令中携带HARQ进程号及与HARQ进程号对应的第一基带参数和/或第一传输时间间隔,终端可以根据与HARQ进程号对应的第一基带参数和/或第一传输时间间隔确定与HARQ进程号对应的第一基带参数和/或第一传输时间间隔。
在本申请实施例中,若初传调度信令中仅携带与HARQ进程号对应的第一传输时间时间间隔,终端则根据HARQ进程号对应的第一传输时间间隔确定与该HARQ进程号对应的第一传输时间间隔,然后根据初传调度信令中包含的资源指示信息及资源与基带参数的映射信息确定第一基带参数。
对于上述两种实现方式,本领域普通技术人员可以根据实际需要进行选择,在本申请实施例中不作具体限定。
第二种:
所述终端接收由所述网络侧设备发送的重传调度信令;

在具体实现过程中,在终端接收由网络侧设备发送的重传调度信令后,终端则根据重传调度信令确定重传调度信令针对的HARQ实体的HARQ进程号及对应的第二基带参数和/或第二传输时间间隔。
在本申请实施例中,终端确定与HARQ进程号对应的第二基带参数和/或第二传输时间间隔包括但不限于以下三种方式,下面分别对这三种实现方式进行描述,具体的:
所述终端根据所述重新调度信令确定HARQ进程号,其中,第二基带参数和/或第二传输时间间隔等于所述HARQ进程号在初传使用的第一基带参数和/或第一传输时间间隔;或,
所述终端根据所述重传调度信令中携带的HARQ进程号对应的第二基带参数和/或第二传输时间间隔确定所述第二基带参数和/或所述第二传输时间间隔;或,
所述终端根据所述重传调度信令中携带的HARQ进程号对应的第二传输时间间隔确定所述第二传输时间间隔;根据所述重传调度信令中携带的资源指示信息,以及资源和基带参数的映射信息确定所述第二基带参数。
在具体实现过程中,在重传调度信令中仅包含HARQ进程号时,则表明重传时使用的第二基带参数和/或第二传输时间间隔与初传时使用的第一基带参数和/或第一传输时间间隔相同,此时,终端则根据重传调度信令确定HARQ进程号,及与该HARQ进程号对应的第一基带参数和/或第二基带参数。
在具体实现过程中,若重传调度信令中携带HARQ进程号及与HARQ进程号对应的第二基带参数和/或第二传输时间间隔,终端可以根据与HARQ进程号对应的第二基带参数和/或第二传输时间间隔确定与HARQ进程号对应的第二基带参数和/或第二传输时间间隔。
在本申请实施例中,若重传调度信令中仅携带与HARQ进程号对应的第二传输时间间隔,终端则根据HARQ进程号对应的第二传输时间间隔确定与该HARQ进程号对应的第二传输时间间隔,然后根据重传调度信令中包含的 资源指示信息及资源与基带参数的映射信息确定第二基带参数。
对于上述三种实现方式,本领域普通技术人员可以根据实际需要进行选择,在本申请实施例中不作具体限定。

HARQ定时关系;
非连续接收DRX定时器相关配置信息。
在本申请实施例中,最大上行/下行HARQ传输次数表明一个HARQ进程对应的数据的最大发送次数,在超出最大上行/下行HARQ传输次数后,则放弃重传。
在本申请实施例中,调度定时关系为接收到网络发送的调度信令到对应的数据传输时刻之间的时间间隔;

在本申请实施例中,网络侧设备可以通过包括但不限于以下两种方式确定与终端对应的HARQ配置信息,下面分别对这两种实现方式进行描述。
所述网络侧设备为所述每个聚合小区配置一套HARQ配置信息;或
所述网络侧设备根据每个基带参数和/或传输时间间隔配置一套HARQ配置信息。
在具体实现过程中,网络侧设备可以为每个聚合小区配置一套HARQ配置信息。
网络侧设备也可以基于每个基带参数和/或传输时间间隔配置一套HARQ配置信息,在该实现方式中,无论是初传还是重传都是根据该进程对应的基带参数和/或传输时间间隔配置确定对应的HARQ配置信息。下面分别进行描述。
在本申请实施例中,所述网络侧设备根据每个基带参数和/或传输时间间隔配置一套HARQ配置信息,包括:
若初传和重传使用的基带参数和/或传输时间间隔不同,所述网络侧设备根据与所述初传对应的第一基带参数和/或第一传输时间间隔确定所述最大上行和/或下行HARQ传输次数;或
所述网络侧设备根据与所述重传对应的第二基带参数和/或第二传输时间间隔确定所述最大上行和/或下行HARQ传输次数。
在具体实现过程中,在重传和初传时使用的基带参数和/或传输时间间隔相同时,网络侧设备则基于初传时的第一基带参数和/或第一传输时间间隔确定最大上行/下行HARQ传输次数。
在重传和初传时使用的基带参数和/或传输时间间隔不同时,网络侧设备可以基于初传时的第一基带参数和/或第一传输时间间隔确定最大上行/下行HARQ传输次数,也可以基于重传时的第二基带参数和/或第二传输时间间隔确定最大上行/下行HARQ传输次数。
在具体实现过程中,在重传和初传时使用的基带参数和/或传输时间间隔不同时,具体采用上述两种方式中的哪一种,包括如下步骤:
所述网络侧设备获取协议约定或网络侧设置;
所述网络侧设备根据所述协议约定或所述网络侧设置,确定根据与所述初传对应的第一基带参数和/或第一传输时间间隔确定所述最大上行和/或下行HARQ传输次数;或根据与所述重传对应的第二基带参数和/或第二传输时间间隔确定所述最大上行和/或下行HARQ传输次数。
在具体实现过程中,网络侧设备获取协议约定或网络侧设置,然后根据协议约定或网络侧设置来确定是采用根据与初传对应的第一基带参数和/或第一传输时间间隔确定最大上行/下行HARQ传输次数,还是采用根据与重传对应的第二基带参数和/或第二传输时间间隔确定最大上行和/或下行HARQ传输次数。
在本申请实施例中,在网络侧设备向终端发送与终端对应的HARQ配置信息之后,则执行步骤202:所述网络侧设备向所述终端发送调度信令,以使所述终端根据所述调度信令确定所述调度信令针对的所述HARQ实体的 HARQ进程号及与所述HARQ进程号对应的基带参数和/或传输时间间隔。
在网络侧设备向终端发送调度信令时,会根据终端的属性信息,如:终端的速度、终端对应的频点信息或终端的业务类型,或者上述任意一种或两种组合来确定确定HARQ实体中被调用的HARQ进程及与该进程号对应的第一基带参数和/或第一传输时间间隔,或者通过其它属性参数确定,在本申请实施例中不作具体限定。
在具体实现过程中,高速终端使用的numerology和低速终端使用的numerology不同;高频和低频使用的numerology也不相同;不同的业务,如:uRLLC(Ultra Reliable & Low Latency Communication,超可靠与超低时延业务)和eMBB(Enhanced Mobile Broadband,增强型移动互联网业务)使用的numerology可能不同,在此,就不再一一举例了。
在本申请实施例中,网络侧设备向终端发送的调度信令可以为初传调度信令,也可以为重传调度信令,下面分别对这两种情况进行描述。
第一种:
所述网络侧设备向所述终端发送初传调度信令;
其中,所述初传调度信令中携带与HARQ进程号对应的第一基带参数和/或第一传输时间间隔;或,
所述初传调度信令中携带与HARQ进程号对应的第一传输时间间隔和调度的资源指示信息。
在具体实现过程中,初传调度信令包括但不限于以下两种实现方式。
(1)、初传调度信令中携带与HARQ进程号对应的第一基带参数和/或第一传输时间间隔,以使终端根据初传调度信令,确定初传调度信令针对的HARQ进程号的第一基带参数和/或第一传输时间间隔。
(2)所述初传调度信令中携带与HARQ进程号对应的第一传输时间间隔和调度的资源指示信息。
在第二种实现方式中,所述方法还包括:
所述网络侧设备向所述终端发送资源和基带参数的映射信息,以使所述 终端根据所述资源指示信息及所述资源和基带参数的映射信息确定第二基带参数。
在具体实现过程中,初传调度信令中携带与HARQ进程号对应的第一传输时间间隔,以使终端根据初传调度信令确定与HARQ进程号对应的第一传输时间间隔,同时向终端发送资源和基带参数的映射信息,以使终端根据初传调度信令中包含的资源指示信息及资源和基带参数的映射信息确定与HARQ进程号对应的第一基带参数。
第二种:
所述网络侧设备向所述终端发送重传调度信令;
其中,所述重传调度信令携带HARQ进程号,不携带与所述HARQ进程号对应的第二基带参数和/或第二传输时间间隔;或,
所述重传调度信令携带HARQ进程号,以及与所述HARQ进程号对应的第二基带参数和/或第二传输时间间隔;或,
所述重传调度信令中携带的HARQ进程号对应的第二传输时间间隔和调度的资源指示信息。
在本申请实施例中,网络侧设备向终端发送重传调度信令的具体实现,包括如下步骤:
所述网络侧设备确定所述重传的次数是否达到所述最大上行/下行HARQ传输次数;
若未达到所述最大上行/下行HARQ传输次数,所述网络侧设备向所述终端发送重传调度信令。
在本申请实施例中,当网络侧设备为终端的每个聚合小区配置一套HARQ配置信息时,则直接从HARQ配置信息中确定最大上行/下行HARQ传输次数;若网络侧设备根据每个基带参数和/或传输时间间隔配置HARQ配置信息,则需要从HARQ配置信息中确定出与重传时采用的第二基带参数和/或第二传输时间间隔对应的最大上行/下行HARQ传输次数,然后确定重传的次数是否达到最大上行/下行HARQ传输次数,在未达到最大HARQ传输次 数时,网络侧设备向终端发送重传调度信令。
在本申请实施例中,重传调度信令包括但不限于以下三种实现方式。
(1)重传调度信令携带HARQ进程号,不携带与所述HARQ进程号对应的第二基带参数和/或第二传输时间间隔.
在该实现方式中,重传使用的第二基带参数和/或第二传输时间间隔与初传使用的第一基带参数和/或第一传输时间间隔相同。这样,在重传调度信令中仅携带HARQ进程号,以使终端根据重传调度信令确定该重传调度信令对应的HARQ进程号及与该进程号对应的第二基带参数和/或第二传输时间间隔。
(2)所述重传调度信令携带HARQ进程号,以及与所述HARQ进程号对应的第二基带参数和/或第二传输时间间隔。
在该实现方式中,重传使用的第二基带参数和/或第二传输时间间隔与初传使用的第一基带参数和/或第一传输时间间隔不同。这样,在重传调度信令则要携带与HARQ进程号对应的第二基带参数和/或第二传输时间间隔,以使终端根据重传调度信令确定重传调度信令针对的HARQ进程号及与HARQ进程号对应的第二基带参数和/或第二传输时间间隔。
(3)所述重传调度信令中携带的HARQ进程号对应的第二传输时间间隔和调度的资源指示信息。
在该实现方式下,所述方法还包括:
所述网络侧设备向所述终端发送资源和基带参数的映射信息,以使所述终端根据所述资源指示信息及所述资源和基带参数的映射信息确定第二基带参数。
在具体实现过程中,重传调度信令中携带与HARQ进程号对应的第二传输时间间隔,以使终端根据重传调度信令确定与HARQ进程号对应的第二恶传输时间间隔,同时向终端发送资源和基带参数的映射信息,以使终端根据重传调度信令中包含的资源指示信息及资源和基带参数的映射信息确定与HARQ进程号对应的第二基带参数。
