具体实施方式
下文中将结合附图对本申请的实施例进行详细说明。需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且,虽然在流程图中示出了逻辑顺序,但是在某些情况下,可以以不同于此处的顺序执行所示出或描述的步骤。
对于下行时隙聚合,3GPP在38.213规范中提到:基站需连续发送pdsch-AggregationFactor(该参数的取值在38.331规范中定义)个时隙的数据(包括新 传数据和重传数据),终端在连续接收完pdsch-AggregationFactor个时隙的数据后进行HARQ(Hybrid Automatic Repeat reQuest,混合自动重传请求)反馈。
对于上行时隙聚合,3GPP在38.321规范中提到:终端需连续发送pusch-AggregationFactor(该参数的取值在38.331规范中定义)个时隙的数据(包括新传数据和重传数据),基站在连续接收完pusch-AggregationFactor个时隙的数据后才进行HARQ反馈处理。
由上可知,目前的时隙聚合处理策略存在以下不足:终端(或基站)是在接收完pdsch-AggregationFactor(或pusch-AggregationFactor)个时隙的数据才反馈HARQ确认,如此一来,增加了数据传输的时延、降低了HARQ进程的使用效率、降低了资源块(RB,Resource Block)和控制信道单元(CCE,Control Channel Element)的使用效率。
本申请实施例提出一种时隙聚合处理方法,以弥补目前的时隙聚合处理策略的不足,相较于目前的时隙聚合处理策略,本申请实施例提供的时隙聚合处理方法可以缩短时隙聚合数据的解码时长,降低数据传输时延,提高HARQ进程的使用效率。
图1为本申请实施例提供的时隙聚合处理方法的应用场景示意图。如图1所示,实施本申请实施例提供的时隙聚合处理方法的通信系统可以包括网络设备120和终端设备100。
应理解,图1所示的通信系统仅仅是一个示例,本申请实施例不限定于此。本申请实施例的技术方案可以应用于各种通信系统,例如:长期演进(Long Term Evolution,LTE)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、5G新空口(New Radio NR)通信系统等。
其中,网络设备120可以是LTE中的演进型基站(Evolutional Node B,eNB或eNodeB)、5G网络中的基站设备、或者未来通信系统中的基站等。
终端设备100也可称为接入终端、用户设备(User Equipment,UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。例如,终端设备100可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、或者5G网络中的终端设备等。然而,本申请对此并不限定。
图2为本申请实施例提供的一种时隙聚合处理方法的流程图。本实施例提供的时隙聚合处理方法可以应用于接收端;比如,接收端可以为网络设备,发送端可以为终端设备; 或者,接收端可以为终端设备,发送端可以为网络设备。
如图2所示,本实施例提供的时隙聚合处理方法包括以下过程:
S201、接收端接收发送端发送的时隙聚合数据;
S202、当接收端正确解码本次时隙聚合中第N个时隙发送的数据,则接收端进行HARQ ACK反馈处理,并停止解码本次时隙聚合中第N个时隙之后的时隙发送的数据;其中,N为正整数且N小于本次时隙聚合的聚合因子。
其中,一次时隙聚合的聚合因子可以指一次时隙聚合中的总时隙的个数。
在本实施例中,接收端在接收时隙聚合数据后,进行数据解码,只要在最后一个时隙数据之前正确解码数据即可以提前进行HARQ ACK反馈处理,无需在接收完本次时隙聚合的全部时隙的数据后再进行HARQ ACK反馈处理,从而可以降低数据传输时延,提高HARQ进程的使用效率。
在本实施例中,在S201之后,本实施例的时隙聚合处理方法还可以包括:当接收端未正确解码本次时隙聚合中第N个时隙发送的数据,则接收端接收并解码本次时隙聚合中第N+1个时隙发送的数据。
在一示例性实施方式中,本实施例的时隙聚合处理方法还可以包括:当接收端接收到本次时隙聚合中最后一个时隙发送的数据,且未正确解码最后一个时隙发送的数据,则接收端进行HARQ非确认(NACK)反馈处理。
在一示例性实施方式中,发送端可以为网络设备,接收端可以为终端设备;相应地,接收端进行HARQ ACK反馈处理,可以包括:接收端向发送端发送HARQ ACK消息。其中,网络设备接收到HARQ ACK消息后,可以释放对应的HARQ进程,以便再次使用,从而提高HARQ进程的使用效率。
在本示例性实施方式中,对于下行时隙聚合,基站(作为发送端)从本次时隙聚合的第一个时隙发送数据,终端(作为接收端)的物理层接收到基站发送的数据后就解码数据,只要正确解码数据就停止解码本次时隙聚合中后面时隙发送的数据、将数据提交给高层并给基站反馈HARQ确认消息;基站接收到终端反馈的HARQ确认消息后就释放相应的HARQ进程(HARQ Process)以便再次使用。在本示例中,如果本次时隙聚合中还有时隙没有发送,则基站可以停止这些时隙上的数据发送,以便节省资源块(RB,Resource Block)和控制信道单元(CCE,Control Channel Element)资源,并提高RB和CCE资源的利用率。
在一示例性实施方式中,发送端可以为终端设备,接收端可以为网络设备;相应地,接收端进行HARQ ACK反馈处理,可以包括:接收端的物理层向介质访问控制(MAC,Media  Access Control)层反馈HARQ ACK消息;MAC层接收到HARQ ACK消息后,释放对应的HARQ进程。
在本示例性实施方式中,接收端进行HARQ ACK反馈处理之后,本实施例的时隙聚合处理方法还可以包括:当本次时隙聚合中存在尚未发送数据的时隙,接收端通过下行控制指示(DCI,Downlink Control Information)消息的新数据指示(NDI,New Data Indication)信息,通知发送端在本次时隙聚合中尚未发送数据的时隙上发送下一次时隙聚合的数据。如此一来,可以节省RB和CCE资源,并提高RB和CCE资源的利用率。
在本示例性实施方式中,对于上行时隙聚合,终端(作为发送端)从本次时隙聚合的第一个时隙发送数据,基站(作为接收端)的物理层接收到数据后就解码数据,只要正确解码数据就停止解码本次时隙聚合中后面时隙发送的数据、将数据提交给高层并给MAC层反馈HARQ确认消息;基站的MAC层收到HARQ确认消息后就释放相应的HARQ进程(HARQ Process)以便再次使用。在本示例中,如果本次时隙聚合中还有时隙没有发送,则基站通过DCI的NDI来通知终端在这些时隙上发送下次时隙聚合的数据,而非本次时隙聚合的数据,以便节省RB和CCE资源并提高RB和CCE资源的利用率。
相较于目前的时隙聚合策略,本申请实施例提供的时隙聚合处理方法中,在一次时隙聚合的最后一个时隙数据之前正确解码数据,即可进行HARQ确认反馈,并停止解码本次时隙聚合中后面时隙发送的数据,从而可以缩短时隙聚合数据的解码时长,降低数据传输时延;而且,通过提前进行HARQ确认反馈可以提前释放HARQ进程,以便HARQ进程再次使用,提高了HARQ进程的使用效率;另外,在接收端提前进行HARQ确认反馈时,发送端可以停止时隙聚合中未发送时隙的数据发送,从而可以节省RB和CCE资源,并提高RB和CCE资源的利用率。
图3为本申请实施例提供的时隙聚合处理方法的一种示例流程图。本示例性实施例中,以发送端为基站,接收端为终端为例,说明下行时隙聚合处理过程。
如图3所示,本示例实施例提供的时隙聚合处理方法,包括以下过程:
S300、基站发送时隙聚合数据。其中,当有下行数据发送时,基站从第一个可用的下行时隙开始连续pdsch-AggregationFactor(对应上述的聚合因子)个时隙发送数据,其中,本时隙聚合中第一个时隙发送的是新传数据,后面时隙发送的是重传数据。
S301、终端接收基站下发的数据。
S302、终端解码收到的数据,并确定是否正确解码收到的数据。如果终端正确解码了基站下发的数据,则执行S303;如果终端未正确解码基站下发的数据,则执行S305。
S303、在终端正确解码基站下发的数据时,终端给基站发送HARQ ACK消息,停止解调本次时隙聚合中后面时隙发送的数据,并将解码出的数据提交给高层。
S304、基站接收到终端反馈的HARQ ACK消息后,进行HARQ ACK处理。其中,基站接收到终端的HARQ ACK消息后就释放相应的HARQ进程;如果本次时隙聚合中还有时隙没有发送,则基站停止这些时隙的数据发送。
S305、在终端没有正确解码基站下发的数据时,终端确定是否接收到本次时隙聚合的最后一个时隙发送的数据。其中,如果终端接收了pdsch-AggregationFactor个时隙的数据,则说明本时隙是一次时隙聚合的最后一个时隙,执行S306,即终端向基站反馈HARQ NACK消息;否则(即终端当前未正确解码的数据不是最后一个时隙数据),返回S301。
S307、基站接收到终端反馈的HARQ NACK(非确认)消息后,进行HARQ NACK处理。其中,基站接收到终端反馈的HARQ NACK消息后,说明传输数据失败,会在随后对本次时隙聚合进行重传。
图4为本申请实施例提供的时隙聚合处理方法的另一种示例流程图。本示例性实施例中,以发送端为终端,接收端为基站为例,说明上行时隙聚合处理过程。
如图4所示,本示例实施例提供的时隙聚合处理方法,包括以下过程:
S400、终端发送时隙聚合数据。其中,当有上行数据发送时,终端从第一个可用的上行时隙开始连续pusch-AggregationFactor(对应上述的聚合因子)个时隙发送数据,其中,本时隙聚合中第一个时隙发送的是新传数据,后面时隙发送的是重传数据。
S401、基站接收终端发送的数据。
S402、基站解码收到的数据,并确定是否正确解码收到的数据。如果基站正确解码了终端发送的数据,则执行S403;如果基站未正确解码终端发送的数据,则执行S405。
S403、在基站正确解码终端发送的数据时,基站的物理层向基站的MAC层发送HARQ ACK消息、停止解调本次时隙聚合中后面时隙发送的数据,并将解码出的数据提交给高层。
S404、基站进行HARQ ACK处理。其中,基站的MAC层接收到HARQ ACK消息后就释放相应的HARQ进程;如果本次时隙聚合中还有时隙没有发送,则基站通过DCI的NDI来通知终端在这些时隙上发送下次时隙聚合的数据,而非本次时隙聚合的数据。
S405、在基站没有正确解码终端发送的数据时,基站确定是否接收到本次时隙聚合的最后一个时隙发送的数据。其中,如果基站接收了pusch-AggregationFactor个时隙的数据,则说明本时隙是一次时隙聚合的最后一个时隙,执行S406,即基站的物理层向MAC层发送HARQ NACK消息;否则(即基站当前未正确解码的数据不是最后一个时隙数据),返 回S401。
S407、基站的MAC层接收到HARQ NACK消息后,进行HARQ NACK处理。其中,基站的MAC层接收到HARQ NACK消息后,说明传输数据失败,会在随后对本次时隙聚合进行重传。

图8为本申请实施例中TDD制式下聚合因子为4时上行时隙聚合的处理示例图。在图8中,D表示下行时隙,U表示上行时隙,S表示特殊时隙,数字表示时隙编号。
在本示例性实施例中,TDD制式下,对于上行时隙聚合,不同帧结构,设置不同的聚合因子;基站能在时隙聚合内的最后一个时隙前正确解码数据、将数据提交给高层并释放HARQ进程,基站通过DCI的NDI来通知终端在本次时隙聚合中未发送数据的时隙发送下次时隙聚合的数据,而非本次时隙聚合的数据。图8描述了2.5ms帧结构聚合因子为4的情况下上行时隙聚合确认(ACK)反馈处理,采用本实施例提供的时隙聚合处理方法的HARQ ACK消息的反馈位置可能是图8中虚箭头所指的位置,而图8中实箭头所指的位置就是目前时隙聚合处理策略的HARQ ACK反馈位置。对于聚合因子为其他值、其他帧结构、TDD制式下的上行时隙聚合,处理策略与本实施例相同,故不再一一穷举。
