Abstract
本公开实施例公开了一种数据传输的方法、设备和系统,该方法可以包括:网络侧接收UE上报的能力信息;所述网络侧基于所述UE的能力信息与预先获取到的UE当前的业务类型中的至少一项,向所述UE发送配置指示信息;网络侧根据配置指示信息向UE发送数据,或根据配置指示信息接收由UE发送的数据。
Description
本公开涉及无线通信技术,尤其涉及一种数据传输的方法、设备和系统。
一个完整的混合自动请求重传请求(HARQ,Hybrid Automatic Repeat Request)进程process从传输到反馈所需要的环路时间(RTT,Round Trip Time)一共包含8个传输时间间隔(TTI,Transmission Time Interval),如图1所示,分别为eNB(effective noise bandwidth,有效噪声带宽)处理数据时间(1.5TTI);eNB传输数据延时(1TTI);UE处理数据时间(1.5TTI);UE处理反馈时间(1.5TTI);UE传输反馈时间(1TTI);eNB处理反馈时间(1.5TTI)。为了避免新传输数据和重传数据冲突,HARQ(Hybrid Automatic Repeat reQuest,混合自动重传请求)进程的数量可以限定为HARQ RTT的数量,
当前,通过HARQ进程进行传输和反馈的时间关系是固定的。但是对于跨基站载波聚合HARQ过程,需要说明的是,用户设备(UE,User Equipment)在次基站SeNB上接收下行数据,而在主基站MeNB上反馈上行数据。由于两个基站间的HARQ RTT为11TTI,而UE实际可用的HARQ process数量为8,则为了避免UE的新传和重传冲突,如图2中的null(无效)所示,网络侧会停止调度3个TTI,从而导致UE的数据传输率下降。
而对于如图3所示的跨基站协同多点传输(CoMP,Coordinated Multiple Points),需要说明的是,eNB2需要将接收到的数据传输到eNB1,eNB1将从UE接收到的数据和从eNB2接收到数据进行合并解码,来提高解码成功率。由于UE需要在n+4(其中n为UE发送数据的子帧)的子帧位置接收到网络侧的反馈,因此对于eNB间的延时需要小于3ms。
通过上述的场景描述,不难发现,当前HARQ进程进行传输和反馈的时间关系是固定的,就会导致限制网络部署的场景。对于不同的业务,由于有不同的延时需求,会导致UE的数据收发延时增加。

S603:网络侧将承载有配置指示信息的RRC连接重配置消息发送至UE;
S604:网络侧和UE按照配置指示信息中所指定的时间点进行数据传输。
可以理解地,当UE接收到配置指示信息后,解析获得配置指示信息中的时间点,于是就会与网络侧按照配置指示信息所指定的时间点进行数据传输。
示例性地,对于下行数据来说,如图7所示,网络侧在发送下行数据的时候可以指定HARQ进程编号,UE在子帧n接收到数据,在子帧n+5发送该接收数据的反馈信息;如果反馈为NACK,则UE在n+9接收网络侧在该HARQ进程的重传数据。需要说明的是,总共可以用的下行HARQ进程数量为10。
对于上行数据来说,如图7所示,UE在子帧n发送数据,在子帧n+5接收到网络侧针对该发送数据的反馈信息,如果反馈为NACK,则UE在n+9在该HARQ进程向网络侧发送重传数据。
示例性实施例二
与示例性实施例一相比,对于步骤S602和S603来说,在本示例性实施例中,对应为在网络侧通过PDCCH调度下行数据传输的时候,向UE发送配置指示信息,因此,此时配置指示信息包括以下至少一种信息:
下行数据传输的HARQ反馈时间;
下行数据传输的HARQ重传时间。
由于PDCCH仅用于传输下行控制数据,仍然以图7为例,UE在子帧n接收到数据,在子帧n+5发送该接收数据的反馈信息,如果反馈为NACK,则UE在n+9接收该HARQ进程的重传数据。
需要说明的是,UE可用的下行HARQ进程数量仍然可以通过网络侧将其承载于RRC配置消息之中进行发送。
示例性实施例三
与示例性实施例一相比,对于步骤S602和S603来说,在本示例性实施例中,对应为在网络侧通过PDCCH调度上行数据传输的时候,向UE发送配置指示信息,因此,此时配置指示信息包括以下至少一种信息:
上行数据传输的HARQ反馈时间;
上行数据传输的HARQ重传时间。
由于PUCCH仅用于传输上行控制数据,仍然以图7为例,UE在子帧n发送数据,网络侧在子帧n+5发送该发送数据的反馈信息,UE接收该发送数据的反馈信息,如果反馈为NACK,则UE在n+9发送该HARQ进程的重传数据。
需要说明的是,UE可用的上行HARQ进程数量仍然可以通过网络侧将其承载于RRC配置消息之中进行发送。
通过上述三个示例性实施例,可以得知,由于网络侧对UE进行HARQ的数据发送或反馈或重传的时间点进行了指示,因此,能够适应更为灵活的网络部署并降低UE的业务传输延时。
