Description
本公开涉及通信技术领域,尤其涉及一种传输HARQ反馈信息的方法、终端及基站。
在无线通信***中,由于无线信道的时变特性以及多径衰落的影响,会对信号的传输带来影响从而导致数据传输的失败。为了解决这个问题,无线通信***引入了HARQ(Hybrid Automatic Repeat reQuest,混合自动重传请求)的机制,通过接收端的HARQ反馈信息即ACK信号或NACK信号,来反馈数据接收的正确与否;发送端依据上述HARQ反馈信息决定是否需要重新发送已经发送的数据包。在传统的LTE(Long Term Evoluttion,长期演进)***中,数据的传输与ACK/NACK反馈的时间之间存在定时关系。受限于终端的处理能力,在LTE***中,数据的传输与ACK/NACK反馈的时间之间至少有4ms。
随着无线通信技术的发展,移动通信网络逐渐向5G NR(New Radio,新空口)网络演进。新一代通信网络已经可以支持灵活的HARQ反馈机制。对于上行数据传输的HARQ反馈,基站可以通过调度指令来指示是否需要重传已经传输的上行数据。然而,针对每一个HARQ反馈信息使用一个调度信令来携带,信令开销会比较大,另外,对于非授权频谱上工作的通信***来讲,由于信道占用的不确定性,可能会出现基站要在同一个传输单元上传输针对一个终端多个上行数据传输的HARQ反馈信息,此种情况下,对每一个HARQ反馈信息使用单独的调度信令来携带是不合适的。

本公开涉及的执行主体包括:基站和终端,其中,基站可以是设置有大规模天线阵列的基站、子基站等。终端可以是用户设备(User Equipment,UE)、用户节点、移动终端或平板电脑等。在具体实现过程中,基站和终端各自独立,同时又相互联系,共同实现本公开提供的技术方案。
参见图1根据一示例性实施例示出的一种传输HARQ反馈信息的方法流程图,应用于终端中,所述方法可以包括以下步骤:
在步骤11中,获取预设下行HARQ配置信息,所述预设下行HARQ配置信息用于告知所述终端目标下行控制信令的传输特性,所述目标下行信令用于承载任一终端的、至少两个上行数据传输的HARQ反馈信息;
本公开中,终端获取上述预设下行HARQ配置信息的方式可以包括:
方式一,若上述预设下行HARQ配置信息是***协议规定的,上述预设下行HARQ配置信息可以是运营商或终端设备制造商在终端出厂或初始化时,预置于终端中的信息。
方式二,终端可以接收基站下发的预设下行HARQ配置信息。即,上述预设下行HARQ配置信息可以是基站发送给终端的。
其中,终端获取上述预设下行HARQ配置信息的时机,可以包括:
在一实施例中,终端接入小区网络时,通过基站广播的***信息获取,即基站将预设下行HARQ配置信息广播至终端。或者,基站通过单播方式将上述预设下行HARQ配置信息发送给终端。
在另一实施例中,终端可以在准备向基站发送多个上行数据传输之前,从基站获取上述预设下行HARQ配置信息。
例如,终端可以主动请求基站下发所述预设下行HARQ配置信息。或者,基站按照相关技术比如识别到该终端首次接入小区,主动将上述预设下行HARQ配置信息发送给终端。本公开对终端获取上述下行HARQ配置信息的方式不作限制。
在本公开一实施例中,上述预设下行HARQ配置信息可以是基站基于当前终端支持HARQ进程的能力,针对当前终端个性化配置的。
针对此种情况,参见图2根据一示例性实施例示出的另一种传输HARQ反馈信息的方法流程图,上述步骤11可以具体为步骤111。
在步骤111中,接收基站下发的所述预设下行HARQ配置信息。
在上述步骤111之前,所述方法还可以包括:
在步骤10中,向所述基站上报所述终端的设备能力信息,所述设备能力信息表示所述终端对HARQ反馈进程的支持数量,以使所述基站根据所述终端对HARQ反馈进程的支持数量确定所述下行HARQ配置信息。
关于终端上报上述设备能力信息的触发机制,可以是终端在接入基站覆盖的小区网络时,主动向基站上报上述设备能力信息;也可以是终端响应基站的要求,被动上报上述设备能力信息,本公开对此不作限制。
本公开实施例中,若终端UE1当前可以支持的HARQ进程数量为4,则UE1上报的设备能力信息用于告知基站UE1当前可支持的最大HARQ进程数量为4。则基站可以根据UE1的上述设备能力信息,将上述目标下行控制信令的信息比特长度设置为4bit,并通过上述预设下行HARQ配置信息将上述预设信息比特长度告知UE1。
在步骤12中,根据所述预设下行HARQ配置信息,确定所述目标下行控制信令的特征信息;
本公开实施例中,上述预设下行HARQ配置信息至少包括:目标下行控制信令的特征信息。终端在获取上述特征信息之后,可以依据上述特征信息从基站发送的下行信息中确定上述目标下行控制信令。
本公开实施例中,用于确定所述目标下行控制信令的特征信息可以包括以下至少一项:
针对所述终端的下行HARQ反馈信息的预设比特长度信息;
所述目标下行控制信令对应的预设标记信息;
所述目标下行控制信令的传输特性信息。
其中,上述目标下行控制信令的传输特性信息可以包括:预设时频位置、预设HARQ-RNTI值、预设加扰序列。
在步骤13中,根据所述特征信息获取所述终端的目标下行控制信令;
本公开中,终端在完成多个上行数据传输之后,可以利用上述目标下行控制信令的特征信息,监测基站在预设的时频位置上下发的所述目标下行控制信令,所述目标下行控制信令专门用于承载上述多个上行数据传输的HARQ反馈信息。
本公开中,根据目标下行控制信令特征信息的不同,终端可以采用以下至少一种方式检测属于自身的所述目标下行控制信令。
方式一、若所述目标下行控制信令的特征信息为:针对所述终端的下行HARQ反馈信息的预设比特长度信息;其中,上述预设比特长度可以是协议规定的预设比特长度,或者是,基站根据当前终端的能力固定配置或是适时配置的长度信息。
参见图3根据一示例性实施例示出的另一种传输HARQ反馈信息的方法流程图,上述步骤13可以包括:
在步骤1311中,按照所述预设比特长度信息监测下行控制信息;
仍以终端UE1为例,假设,UE1从基站下发的预设下行HARQ配置信息,确定上述目标下行控制信令的特征信息为N个bit。
则UE1根据上述预设比特长度信息N,确定PDCCH(Physical Downlink Control Channel,物理下行控制信道)的最大盲检次数,在PDCCH上监测预设比特长度N的DCI(Downlink Control Information,下行控制信息)。
在步骤1312中,若监测到符合所述预设比特长度的下行控制信息,将所述下行控制信息确定为所述终端的所述目标下行控制信令。
若终端监测到符合预设比特长度N的DCI,则将当前检测到的信息比特长度为N的DCI,确定为上述目标下行控制信令。
本公开实施例,适用于每个终端用于承载HARQ反馈信息的信令长度不同的应用场景中,即通过预设比特长度即可明确识别出上述目标下行控制信令,可以采用针对该终端的下行HARQ反馈信息的预设比特长度信息,简单快捷地识别出上述针对该终端的目标下行控制信令。
方式二、适用于上述目标下行控制信令的信息比特长度与其它类型DCI的信息比特长度相同的场景中。
若***或基站配置的、所述目标下行控制信令的特征信息为:预设标记信息。参见图4根据一示例性实施例示出的另一种传输HARQ反馈信息的方法流程图,上述步骤13可以包括:
在步骤1321中,获取属于所述终端的下行控制信息;
根据相关知识,终端按照最大盲检次数如44,从PDCCH上检测属于自身的DCI。
在步骤1322中,确定当前下行控制信息是否携带有所述预设标记信息;
若检测到属于自身的一个或多个DCI,确定符合目标信息比特长度的每个DCI中是否携带有预设标记信息flag,该预设标记信息用于标识当前DCI属于用于承载上行数据传输的HARQ反馈信息的目标DCI。若在当前DCI中未检测到上述预设标记信息,确定当前DCI并非上述目标下行控制信令;反之,执行下述步骤1323。
在步骤1323中,若所述当前下行控制信息中携带有所述预设标记信息,将所述当前下行控制信息确定为所述目标下行控制信令。
方式三,根据目标下行控制信令的传输特性信息,检测所述目标下行控制信令。
根据上述传输特性信息的不同,上述步骤13的实施可以包括以下至少一种实施方式:
第一种实施方式,对应上述传输特性信息为:传输所述目标下行控制信令的预设时频位置。
则上述步骤13可以包括:若终端在传输单元的预设时频位置检测到属于自身的下行控制信息,则确定所述下行控制信息为目标下行控制信令。
本公开实施例中,基站或***约定将上述目标下行控制信令设置于一个或多个下行传输单元的预置时频位置。假设上述传输单元为一个时隙slot,可以约定在一个时隙的控制区域的预设时频位置承载上述目标下行控制信令。本公开中,上述传输单 元可以是:时隙slot、迷你时隙mini-slot、符号symbol等时域资源单位,本公开对此不作限制。
当终端在一个下行传输单元的控制区域的预设时频位置监测到属于自身的DCI时,可以将上述DCI确定为上述目标下行控制信令。
第二种实施方式,对应上述传输特性信息为:预设HARQ-RNTI值;
则上述步骤13可以包括:若终端采用上述预设HARQ-RNTI值成功检测到属于自身的DCI,则将上述DCI确定为目标下行控制信令。
本公开实施例中,基站或***约定采用预设HARQ-RNTI值标识上述目标下行控制信令。并在通过目标下行控制信令发送多个上行数据传输的HARQ反馈信息时,将上述HARQ-RNTI值加载于针对该终端的目标下行控制信令中。
相应的,终端在监测DCI时,若检测到DCI中的RNTI(RNTI Radio Network Tempory Identity,无线网络临时标识)值与上述预设HARQ-RNTI值相同,将所述DCI确定目标下行控制信令。
第三种实施方式,对应上述传输特性信息为:预设加扰码。
则上述步骤13可以包括:若终端采用上述预设加扰码对检测到的下行控制信息的CRC成功解扰,确定所述DCI属于目标下行控制信令。
本公开实施例中,基站或***约定采用预设加扰码对目标下行控制信令的预设信息字段进行加扰,以标识该下行控制信息属于上述目标下行控制信令。示例性的,上述预设信息字段可以是CRC(Cyclic Redundancy Check循环冗余校验码),或者,该DCI信息域的预设字段。
相应的,终端在检测到属于自身的DCI后,该DCI存在加扰信息,若终端利用上述预设加扰码对加扰部分信息成功解扰,则确定该DCI属于上述目标下行控制信令。
需要说明的是,终端可以结合上述多种检测方式对目标下行控制信令进行检测。例如,当终端按照预设比特长度信息同时检测到多个待选DCI时,还可以依据上述预设标记信息,和/或,传输特性信息进一步识别目标下行控制信令。本公开并不限制仅采用一种方式进行目标下行控制信令识别。
在步骤14中,对所述目标下行控制信令进行解析,得到至少两个上行数据传输的HARQ反馈信息。
参见图5根据一示例性实施例示出的另一种传输HARQ反馈信息的方法流程图,上述步骤14可以包括:
在步骤141中,根据所述下行HARQ配置信息确定每个上行数据传输对应的目标信息域,所述目标信息域用于承载一个预设上行数据传输的HARQ反馈信息;
该步骤的实施可以包括两种情况:
第一种情况,***协议规定有不同上行数据传输的HARQ反馈信息在目标下行信令中的承载位置。比如,对于按照时间由远及近的顺序排列的三个上行数据传输,其HARQ反馈信息分别设置于目标下行控制信令的第1、2、3号信息比特中。即将最早完成的第一上行数据传输的HARQ反馈信息,承载于上述目标下行控制信令的第1个bit中。
此种情况,***可以默认按照时序承载各个上行数据传输的HARQ反馈信息,无需花费信令开销告知终端HRAQ反馈信息的承载位置。
第二种情况,终端获取基站下发的HRAQ反馈信息的传输配置信息。
参见图6根据一示例性实施例示出的另一种传输HARQ反馈信息的方法流程图,上述步骤141可以包括:
在步骤1411中,获取HRAQ反馈信息的传输配置信息;所述HARQ反馈信息的传输配置信息用于告知所述终端至少两个所述上行数据传输的HARQ反馈信息在所述目标下行控制信令中的承载位置;
本公开中,基站可以采用单独的信令将上述HRAQ反馈信息的传输配置信息发送给终端,或者,和上述目标下行控制信令的特征信息通过同一个信令发送至终端。
在步骤1412中,根据所述HARQ反馈信息的传输配置信息,确定每个所述上行数据传输对应的目标信息域。
本公开实施例的适用场景可以是:终端已完成的各上行数据传输的时延敏感度不同,基站可以依据不同数据传输的时延敏感度,将对时延要求较高的上行数据传输的HARQ反馈信息优先设置在前序信息比特中,以便终端可以较早解析出上述时延敏感上行数据传输的HARQ反馈信息,满足不同业务需求。
在步骤142中,从所述目标下行控制信令的不同信息域中获取各个所述上行数据传输的HARQ反馈信息。
终端在确定了不同时序的上行数据传输对应的目标信息域后,从相应信息域中准确解析每个上行数据传输的HARQ反馈信息。
综上,采用本公开提供的传输HARQ反馈信息的方法,终端可以从一个目标下行控制信令中一次性获取多个已完成上行数据传输的HARQ反馈信息,与相关技术相比,可以避免解析多个调度信令,从而提升HARQ反馈信息的解析效率,节约*** 信令开销。
相应的,本公开还提供了一种传输下行混合自动重传请求HARQ反馈信息的方法,可以应用于5G NR***的基站中。
参见图7根据一示例性实施例示出的一种传输HARQ反馈信息的方法流程图,所述方法可以包括:
在步骤21中,确定预设下行HARQ配置信息,所述预设下行HARQ配置信息用于告知终端目标下行控制信令的传输特性,所述目标下行控制信令用于承载任一终端的、至少两个上行数据传输的HARQ反馈信息;
本公开中,上述预设下行HARQ配置信息是针对一种预设HARQ反馈机制确定的配置信息,该HARQ反馈机制为采用一个目标下行控制信令一次向终端反馈多个上行数据传输的HARQ反馈信息。本公开中,每个上行数据传输对应一个HARQ反馈信息。
本公开一实施例中,基站可以在预设触发条件下,启用上述预设HARQ反馈机制。其中,上述预设触发条件可以是:基站检测到终端通过非授权频段资源完成上述多个上行数据传输。在本公开另一实施例中,上述预设触发条件也可以是:基站在预设时间范围内检测到一个终端的多个上行数据传输。
本公开另一实施例中,基站也可以默认采用上述HARQ反馈机制。
本公开中,上述预设下行HARQ配置信息可以包括:所述目标下行控制信令的特性信息,所述特征信息用于告知所述终端如何识别所述目标下行控制信令。
在本公开一实施例中,所述目标下行控制信令的特征信息可以包括以下至少一项:
针对所述终端的下行HARQ反馈信息的预设比特长度信息;
用于标识所述目标下行控制信令的预设标记信息;
所述目标下行控制信令的传输特性信息。其中,所述传输特性信息包括以下至少一项:
传输所述目标下行控制信令的预设时频位置;
预设HARQ-RNTI值;
所述目标下行控制信令的预设加扰序列。
在本公开一实施例中,若所述目标下行控制信令的特征信息为:针对所述终端的下行HARQ反馈信息的预设比特长度信息。上述预设比特长度信息可以是基站为终端随机指定的一个固定信息,比如5bit。在本公开另一实施例中,基站也可以根据终 端当前支持HARQ反馈进程的能力,为所述终端动态配置的一个长度信息。
参见图8根据一示例性实施例示出的另一种传输HARQ反馈信息的方法流程图,上述步骤21可以包括:
在步骤211中,获取所述终端的设备能力信息,所述设备能力信息表示所述终端对HARQ反馈进程的支持数量;
该步骤与上述步骤10对应,具体实施过程可以参见上述步骤10的描述,此处不再赘述。其中,终端支持HARQ反馈进程的能力可以是固定配置的,或者,适时配置的。本公开中,终端支持HARQ反馈进程的能力可以表示为终端可支持HARQ反馈进程的最大数量。
在步骤212中,根据所述终端对HARQ反馈进程的支持数量确定所述目标下行控制信令的预设比特长度信息;
其中,上述预设比特长度可以不小于所述终端对HARQ反馈进程的支持数量。例如,若终端当前可以最多支持4个HARQ反馈进程,则上述预设比特长度信息可以不小于4bit,比如5bit。
在步骤213中,根据预设比特长度信息确定所述下行HARQ配置信息。
参见图9根据一示例性实施例示出的另一种传输HARQ反馈信息的方法流程图,在上述步骤21之后,所述方法还可以包括:
在步骤22中,将所述预设下行HARQ配置信息发送给所述终端,以使所述终端根据所述预设下行HARQ配置信息获知所述目标下行控制信令。
该实施例与上述图2所示实施例相对应,具体实施过程相互参见即可。
其中,基站可以下述任一信令将所述预设下行HARQ配置信息发送给所述终端:广播信令、上层信令或物理层的PDCCH(Physical Downlink Control Channel,物理下行控制信道)信令,下发给目标UE。其中,上层信令可以是RRC(Radio Resource Control,无线资源控制)信令、MAC(Medium Access Control,媒介访问控制)CE(Control Element,控制单元)信令。
在步骤23中,根据所述预设下行HARQ配置信息,将HARQ反馈信息加载于所述目标下行控制信令中,发送给所述终端。
假设基站需要对终端已完成的4个上行数据传输反馈HARQ信息,则基站可以采用至少一种方式,将HARQ反馈信息加载于所述目标下行控制信令中,发送给所述终端:
方式一、将上述4个HARQ反馈信息加载于长度为5bit的目标下行控制信令 中。
方式二,将上述4个HARQ反馈信息加载于固定长度的DCI中,该固定长度也是其它类型DCI的长度;之后,在该DCI的预设信息域中添加预设标记信息,该预设标记信息用于表示当前DCI属于专门承载HARQ反馈信息的专用信令。
方式三,在一个DCI中加载上述4个HARQ反馈信息之后,还可以设置上述至少一种传输特性信息,比如,采用预设加扰序列对该DCI的预设信息字段进行加扰;或者,在该DCI中添加针对上述终端的预设HARQ-RNTI值;或者,将上述DCI加载于控制区域预设时频位置的资源中,发送给终端。
关于基站按照什么顺序在上述目标下行控制信令中加载各个HARQ反馈信息,本公开一实施例中,基站可以按照每个上行数据传输的完成时序,按照先后顺序将HARQ反馈信息依次加载于目标控制信令的信息域中。
仍以4个上行数据传输为例,假设分别对应HARQ进程1、HARQ进程2、HARQ进程3、HARQ进程4;在DCI中利用第1、2、3、4bit承载上述各个进程的HARQ反馈信息。则,HARQ进程与承载位置的对应关系,可以如表一所示:
HARQ进程编号 | 承载位置标识 |
HARQ进程1 | 第1bit |
HARQ进程2 | 第2bit |
HARQ进程3 | 第3bit |
HARQ进程4 | 第4bit |
表一
加载后的目标下行控制信令,可以如图10-1所示,其中,第0号比特可以用于记载预设标记信息。
在本公开另一实施例中,考虑到不同上行数据传输业务的时延敏感特性,基站可以综合考虑数据传输时序和业务敏感性,将时延敏感业务如eMBB(enhanced Mobile Broad Band,增强带宽)业务的HARQ反馈信息设置在靠前位置。
例如,假设上述HARQ进程4对应的是时延敏感业务,则基站可以将其反馈信息设置于第1bit,若其余3个上行数据传输业务具有相同的、较次的时延敏感性,比如mMTC(massive Machine Type Communication,海量机器通信类)等业务,可以按照时序设置目标信息域。示例性地,本公开实施例中,HARQ进程与承载位置的对应关系,可以如表二所示:
HARQ进程编号 | 承载位置标识 |
HARQ进程4 | 第1bit |
HARQ进程1 | 第2bit |
HARQ进程2 | 第3bit |
HARQ进程3 | 第4bit |
表二
相应的,基站可以根据上述表二生成HARQ反馈信息的传输配置信息,并将该传输配置信息发送给终端。之后,根据所述传输配置信息,将所述至少两个上行数据传输的HARQ反馈信息加载于所述目标下行控制信令的指定信息域中。如上示例,加载后的目标下行控制信令,可以如图10-2所示。
本公开实施例中,基站可以兼顾不同上行数据传输的时序和所承载业务的时延敏感性确定不同HARQ反馈信息的承载位置,尽可能满足不同业务需求,提升5G NR网络的用户体验。
