Description

业务反馈方法和通信设备 技术领域
本发明涉及通信技术,尤其涉及一种业务反馈方法和通信设备。
背景技术
现有长期演进(Long Term Evolution,简称LTE)系统中,基站通过时分双工(Time Division Duplexing,简称TDD)系统调度无线设备,共享全部频谱资源。在现有的TDD系统中,通过混合自动重传(Hybrid Automatic Repeat Request,简称HARQ)机制提高物理层的传输可靠性,HARQ在时间维度的传输时序被称为HARQ定时。如图1所示的下行HARQ定时示意图(其中,D表示下行子帧,S表示特殊子帧,U表示上行子帧),TDD系统中基站在下行传输子帧0上为用户设备(User Equipment,简称UE)传输下行数据,UE在子帧0上接收该下行数据,之后UE经过固定的数据处理时间后(处理时间至少占4个子帧)对该下行数据进行处理后,UE在上行子帧7上向基站发送反馈信息,该反馈信息可以为肯定应答(Acknowledgement,简称ACK)信息或否定应答(Negative Acknowledgement,简称NACK)信息,从而使得基站根据该反馈信息判断是否给UE调度数据包的重传和新数据包的发送;假设基站在下行子帧3上发送下行数据,则UE也在子帧7上发送反馈信息,此时UE的数据处理时间占4个子帧。因此,图1中的下行HARQ定时可以理解为向UE指示发送反馈信息的子帧位置。
又例如,参见图2所示的上行HARQ定时示意图,假设UE在下行子帧3接收到基站发送的上行传输调度信息(UL grant),随后UE在该上行调度信息指定的上行时频资源处(上行子帧7)传输上行数据;基站在接收到上行传输数据后,在4个子帧后最近的下行传输资源位置(即下一无线帧的特殊子帧1)上向UE传输反馈信息。因此,图2中的上行HARQ定时可以理解为向基站指示发送反馈信息的子帧位置。也就是说,无论是上行HARQ定时,还是下行HARQ定时,其中涉及的HARQ定时均是向接收数据的设备指示反馈信息的子帧位置,使得该接收数据的设备可以及时的向发送数据的设备发送反 馈信息。
但是,现有技术的这种业务反馈的方法,业务数据从发送到反馈的周期过长,无法满足低延时业务的低延时要求。
发明内容
本发明提供一种业务反馈方法和通信设备,用以解决现有技术中的业务反馈方法,业务数据从发送到反馈的周期过长,无法满足低延时业务的低延时要求的技术问题。
第一方面,本发明提供一种业务反馈方法,包括:
第一通信设备接收第二通信设备在第一子帧的第一时频资源上发送的第一业务;所述第一时频资源包括所述第一子帧中的物理控制信道资源、所述第一子帧中的物理共享信道资源和反馈资源中的至少一种资源;
所述第一通信设备在预设的反馈子帧位置上发送所述第一业务对应的第一反馈信息;其中,所述第一时频资源对应在所述第一子帧上的子帧位置和所述反馈子帧位置之间的间隔为第一定时,所述第二通信设备发送第二业务的第二时频资源所对应的子帧位置与所述第一通信设备向所述第二通信设备发送第二反馈信息的第三时频资源所对应的子帧位置之间的间隔为第二定时,所述第一定时小于所述第二定时。
通过第一方面提供的业务反馈方法,第二通信设备在第一时频资源上向第一通信设备发送第一业务,使得第一通信设备在接收到第一业务后有足够的时间对第一业务进行处理,通过对第一子帧的时频资源的重新分配,使得第一通信设备可以在预设的反馈子帧位置上向第二通信设备发送第一反馈信息,因而确保第一业务从发送到接收其对应的第一反馈信息之间的延时(即第一定时),小于第二业务从发送到接收其对应的第二反馈信息之间的延时(即第二定时),即小于传统业务的反馈延时,故,本发明实施例提供的业务反馈方法,缩短了低延时业务数据从发送到反馈的周期,满足低延时业务的低延时要求。
在第一方面的第一种可能的实施方式中,所述第一通信设备在预设的反馈子帧位置上发送所述第一业务对应的第一反馈信息之前,还包括:
所述第一通信设备根据所述第一业务的类型、所述第一业务的大小和第 一映射关系,确定所述反馈子帧位置;所述第一映射关系包括所述第一时频资源与所述第一定时之间的对应关系。
在第一方面的第二种可能的实施方式中,所述第一通信设备在预设的反馈子帧位置上发送所述第一业务对应的第一反馈信息之前,还包括:
所述第一通信设备接收所述第二通信设备根据所述第一业务的类型、所述第一业务的大小和第一映射关系确定的所述反馈子帧位置;所述第一映射关系包括所述第一时频资源与所述第一定时之间的对应关系。
可选的,在第一方面的第三种可能的实施方式中,所述第一通信设备为用户设备UE,所述第二通信设备为基站;所述第一时频资源为所述第一子帧中的所述物理下行控制信道资源,所述第二时频资源为所述第一子帧中的所述物理下行共享信道资源;或者,所述第一时频资源为所述物理下行共享信道资源中的部分资源,所述第二时频资源为所述物理下行共享信道资源中的剩余部分资源;或者,所述第一时频资源为所述物理下行控制信道资源的部分资源和所述物理下行共享信道资源中的部分资源,所述第二时频资源为所述物理下行共享信道资源中的剩余部分资源;
则在所述第一通信设备接收所述第二通信设备在第一子帧的第一时频资源上发送第一业务之前,还包括:所述第一通信设备接收所述第二通信设备发送的第一指示信息,所述第一指示信息用于向所述第一通信设备指示所述第一子帧中包括所述第一业务。在该可能的实施方式下,所述反馈子帧位置为无线帧中距离所述第一子帧最近的且能够传输反馈信息的具有上行传输资源的子帧。
通过该第三种可能的实施方式提供的方法,第二通信设备在第一时频资源上发送第一业务之后,第一通信设备就可以在与该第一时频资源对应的,在无线帧中距离第一子帧最近的且能够传输反馈信息的具有上行传输资源的子帧上发送第一反馈信息,使得第一定时小于第二定时,大大缩短了第一业务的反馈延时。
可选的,在第一方面的第四种可能的实施方式中,所述第一通信设备为用户设备UE,所述第二通信设备为基站,所述第一子帧为type1子帧,所述第一通信设备接收第二通信设备在第一子帧的第一时频资源上发送的第一业务之前,所述方法包括:

该第四种可能的实施方式提供的方法,当UE完成第一业务的接收后,可以在当前第一子帧结束前利用当前第一子帧的上行传输资源向基站发送第一反馈信息,而无需在其他的子帧上去发送第一反馈信息,因此,大大缩短了UE对基站的第一业务进行反馈的时间,因而降低了第一业务的反馈延时。
可选的,在第一方面的第五种可能的实施方式中,所述第一通信设备为用户设备UE,所述第二通信为基站,所述第一子帧为type2子帧,所述第一时频资源为所述第一子帧中用于传输反馈信息的时频资源;则在所述第一通信设备接收第二通信设备在第一子帧的第一时频资源上发送的第一业务之前,还包括:

该第五种可能的实施方式提供的方法,当UE完成第一业务的接收后,可以在当前第一子帧结束前利用当前第一子帧的上行传输资源向基站发送第一反馈信息,而无需在其他的子帧上去发送第一反馈信息,因此大大缩短了UE对基站的第一业务进行反馈的时间,因而降低了第一业务的反馈延时。

则在所述第一通信设备接收第二通信设备在第一子帧的第一时频资源上发送第一业务之前,包括:所述第一通信设备向所述第二通信设备发送第四指示信息,所述第四指示信息用于向所述第二通信设备指示在所述第一子帧的第一时频资源上发送所述第一业务。在该第六种可能的实施方式下,所述反馈子帧位置为距离所述第一子帧最近的且能够传输反馈信息的具有下行传输资源的子帧。
通过该第六种可能的实施方式提供的方法,第二通信设备在第一时频资源上发送第一业务之后,第一通信设备就可以在与该第一时频资源对应的,在无线帧中距离第一子帧最近的且能够传输反馈信息的具有下行传输资源的子帧上发送第一反馈信息,即通过对第一子帧上的时频资源重新分配,大大缩短了第一业务的反馈延时。
可选的,在第一方面的第七种可能的实施方式中,所述第一通信设备为基站,所述第二通信设备为用户设备UE,所述第一子帧为type1子帧,所述第一通信设备接收第二通信设备在第一子帧的第一时频资源上发送的第一业务之前,所述方法包括:所述第一通信设备向所述第二通信设备发送第五指示信息,所述第五指示信息用于向所述第二通信设备指示所述第一时频资源为所述第一子帧中用于传输反馈信息的时频资源。

所述第一通信设备向所述第二通信设备发送第六指示信息,所述第六指示信息用于向所述第二通信设备指示所述第一时频资源为所述第一子帧中物理上行共享信道资源的部分资源。故,在上述第七种或第八种两种可能的实施方式下,所述反馈子帧位置为所述第一子帧的下下一个子帧。
通过该第七种可能的实施方式提供的方法,UE可以利用当前的第一子帧尾部的上行传输资源传输上行数据,无需单独等待一个上行子帧来传输上行数据,这样使得基站可以在第一子帧的下下一个子帧就可以完成第一反馈信息的发送,无需像传统业务(即第二业务)一样需要等待至少4个子帧才进 行反馈信息的发送,因此,本实施方式通过定义第一业务的资源重用位置,大大缩短了UE对基站的第一业务进行反馈的时间,因而降低了了第一业务的反馈延时,实现了低延时的用户数据传输。
可选的,在第一方面的第九种可能的实施方式中,所述第一通信设备为基站,所述第二通信设备为用户设备UE,所述第一子帧为type2子帧,所述第一通信设备接收第二通信设备在第一子帧的第一时频资源上发送的第一业务之前,所述方法包括:
所述第一通信设备在所述第一子帧的前一子帧向所述第二通信设备发送第七指示信息,所述第七指示信息用于向所述第二通信设备指示所述第一时频资源为所述第一子帧中的物理上行共享信道资源的部分资源。故,在该第九种可能的实施方式中,所述反馈子帧位置为所述第一子帧的下一个子帧。
通过该第九种可能的实施方式提供的方法,对第一子帧上的物理上行共享信道资源UL的资源复用,大大缩短了UE对基站的第一业务进行反馈的时间,因而降低了了第一业务的反馈延时。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本申请涉及的业务反馈方法和通信设备,可以适用于LTE系统的网络架构,还可以适用于下一代(4.5G或者5G)通信系统的网络架构。例如,参见图3所示,以LTE系统为例,该LTE系统中包括用户设备、演进型基站(Evolved Node B,简称eNodeB)和演进分组核心网(Evolved Packet Core,简称EPC)。其中,EPC负责核心网部分,信令处理部分为移动管理实体(Mobility Management Entity,简称MME),数据处理部分为服 务网关(Serving Gateway,简称S-GW),eNode B负责接入网部分,也称演进的UMTS陆地无线接入网(Evolved UTRAN,演进的UTRAN)。LTE系统支持与其他3GPP系统互操作,根据双工方式不同LTE系统分为频分双工LTE系统(Frequency Division Duplexing-LTE,简称FDD-LTE)和时分双工LTE系统(Time Division Duplexing-LTE,简称TDD-LTE)。
本申请中涉及的第一通信设备,可以为基站,也可以为UE,本申请中涉及的第二通信设备可以为UE,也可以为基站。当第一通信设备为基站时,第二通信设备为UE;当第一通信设备为UE时,第二通信设备为基站。
另外,本申请中涉及的基站可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换,作为无线终端与接入网的其余部分之间的路由器,其中接入网的其余部分可包括网际协议(IP)网络。基站还可协调对空中接口的属性管理。例如,基站可以是LTE中的演进型基站(NodeB或eNB或e-NodeB,evolutional Node B),本申请并不限定。
本申请中涉及的UE,可以是无线终端。无线终端包括向用户提供语音和/或数据服务的设备,可选的,该设备可以为具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。并且,该无线终端还可以经无线接入网(例如,RAN,Radio Access Network)与一个或多个核心网进行通信,例如该无线终端具体可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,该具有移动终端的计算机可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们可以与核心网进行语音和/或数据的交互。
需要说明的是,本发明实施例涉及的第一子帧可以是LTE系统中任一配比的无线帧中的子帧,还可以是采用图4中所示的新帧结构(type1子帧或type2子帧),所涉及的第一业务可以为反馈延时小于预设延时阈值的业务,例如可以为低延时(low latency)业务,该第一业务可以为承载在物理上行共享信道上或者物理下行共享信道上的数据,即该第一业务也可以称为第一数据;所涉及的第二业务可以为反馈延时大于等于预设延时阈值的业务,该第二业务也可以为承载在物理上行共享信道上或者物理下行共享信道上的数据,即该第二业务也可以称为第二数据。其中,DL 表示用于传输下行信息(可以是下行数据或者下行控制信息)下行传输资源,UL表示用于传输上行信息(可以是上行数据或者上行控制信息)的上行传输资源,GP表示用于保护间隔的资源。
本发明实施例提供的业务反馈方法和通信设备,用以解决现有技术中业务数据从发送到反馈的周期过长,无法满足低延时业务的低延时要求的技术问题。
下面以具体地实施例对本发明的技术方案进行详细说明。下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例中不再赘述。
图5为本发明提供的业务反馈方法实施例一的信令流程图。本实施例涉及的是第二通信设备在第一子帧上的第一时频资源上发送了第一业务之后,第一通信设备在预设的子帧位置上向第二通信设备发送第一反馈信息(该第一反馈信息可以是ACK信息或者NACK信息,下述的第二反馈信息可以是ACK或者NACK信息),从而实现满足低延时业务的低延时反馈的要求。本实施例中,第一通信设备可以为基站,第二通信设备可以UE,或者第一通信设备可以为UE,第二通信设备可以为基站,也就是说,本实施例涉及的方法可以是基站在接收到UE发送的第一业务时,向UE发送反馈信息的过程,也可以是UE在接收到基站发送的第一业务后,向基站发送反馈信息的过程。
如图5所示,该方法包括:
S101:第二通信设备在第一子帧的第一时频资源上向第一通信设备发送第一业务。
具体的,当第一通信设备为UE,第二通信设备为基站时,基站可以自行决定在第一子帧上的第一时频资源上向UE发送第一业务,该第一子帧为下行子帧;当第一通信设备是基站,第二通信设备是UE时,UE则要根据基站的调度指示,确定自身在第一子帧的第一时频资源上发送第一业务,该第一子帧为上行子帧。可选的,该第一业务可以为低延时业务。
上述第一时频资源可以包括第一子帧中的物理控制信道资源,还可以包括物理共享信道资源,还可以包括物理控制信道资源和物理共享信道资源。
具体的,该第一时频资源具体可以包括第一子帧上的物理下行控制信道 资源、第一子帧上的物理下行共享信道资源、物理上行控制信道资源、物理上行共享信道资源、用于传输反馈信息的时频资源中的至少一种时频资源。其中,物理下行控制信道资源可以为第一子帧上用于物理下行控制信道传输(Physical Downlink Control Channel,简称PDCCH)信息的时频资源,还可以为第一子帧上用于传输E-PDCCH信息的时频资源;上述物理上行控制信道资源可以为第一子帧上用于传输物理上行控制信道(Physical Uplink Control Channel,简称PUCCH)信息的时频资源,还可以为第一子帧上用于传输E-PUCCH信息的资源;上述物理下行共享信道资源可以是第一子帧上用于传输物理下行共享信道(Physical Downlink Shared Channel,简称PDSCH)信息的时频资源,还可以是用于传输E-PDCCH信息的时频资源;上述物理上行共享信道资源可以为第一子帧上用于传输物理上行共享信道(Physical Uplink Shared Channel,简称PUSCH)信息的时频资源,上述用于传输反馈信息的时频资源可以是type1子帧中用于传PUCCH信息和参考信号的上行传输资源,还可以是type2子帧中用于传输反馈信息和一些下行指示信息(通过PDCCH传输的信息)的下行传输资源。
需要说明的是,上述PDCCH信息指的是通过PDCCH信道传输的信息,PUCCH信息指的是通过PUCCH信道传输的信息,PDSCH信息指的是通过PDSCH信道传输的信息,PUSCH信息指的是通过PUSCH信道传输的信息。
当第二通信设备在第一时频资源上向第一通信设备发送了第一业务之后,第二通信设备会在第二时频资源上向第一通信设备发送第二业务,可选的,该第二业务为传统的对延时要求不高的业务,该第二时频资源的类型可以与第一时频资源的类型相同,也可以不同,例如,当第一时频资源为第一子帧中的物理下行控制信道资源,则第二时频资源就可以为第一子帧中的物理下行共享信道资源,再例如,第一时频资源为第一子帧上的物理下行共享信道资源中的部分资源,则第二时频资源就可以为物理下行共享信道资源中的剩余部分资源。
S102:第一通信设备接收第二通信设备在第一子帧的第一时频资源上发送的第一业务。
具体的,当第一通信设备为UE,第二通信设备为基站时,第二通信设备可以指示第一通信设备在第一子帧上相应的资源位置(例如可以在第一时频 资源上)接收该第一业务;当第一通信设备为基站,第二通信设备为UE时,第一通信设备可以指示第二通信设备在第一时频资源上发送第一业务,从而使得第一通信设备可以在相应的资源位置上(例如可以在第一时频资源上)接收第二通信设备发送的第一业务。
S103:第一通信设备在预设的反馈子帧位置上发送所述第一业务对应的第一反馈信息。
其中,所述第一时频资源对应在所述第一子帧上的子帧位置和所述反馈子帧位置之间的间隔为第一定时,所述第一通信设备接收所述第二通信设备发送的第二业务的第二时频资源所对应的子帧位置与所述第一通信设备向所述第二通信设备发送第二反馈信息的第三时频资源所对应的子帧位置之间的间隔为第二定时,所述第一定时小于所述第二定时。
具体的,正如上述所描述的,第一子帧会对应不同类型的时频资源,不同类型的时频资源对应在第一子帧上的子帧位置也是不同的。当第一通信设备接收到上述第一业务之后,第一通信设备可以在预设的反馈子帧位置上向第二通信设备发送第一业务对应的第一反馈信息,该预设的反馈子帧位置与第一时频资源对应在第一子帧上的子帧位置之间的间隔可以称为第一定时。当第一通信设备接收到第二业务之后,会在第一子帧的第三时频资源位置上向第二通信设备发送第二反馈信息,该反馈机制可以参照现有技术,例如,第二时频资源对应的子帧位置与第三时频资源对应的子帧位置之间的间隔至少在4个子帧之上,或者间隔4个子帧。在本实施中,第二时频资源所对应的子帧位置与第三时频资源所对应的子帧位置之间的间隔被称为第二定时,上述第一定时小于该第二定时,也就是说,本发明实施例中,第一业务既可以在物理控制信道资源上发送,也可以在物理共享信道资源上发送,并且第一业务在第二业务之前发送,使得第一通信设备在接收到第一业务后有足够的时间对第一业务进行处理,因而确保第一业务从发送到接收其对应的第一反馈信息之间的延时,小于第二业务从发送到接收其对应的第二反馈信息之间的延时,即小于传统业务的反馈延时,故,本发明实施例提供的业务反馈方法,可以缩短低延时业务数据从发送到反馈的周期,满足低延时业务的低延时要求,提高低延时业务的通信质量。
本发明实施例提供的业务反馈方法,第二通信设备在第一时频资源上向 第一通信设备发送第一业务,使得第一通信设备在接收到第一业务后有足够的时间对第一业务进行处理,通过对第一子帧的时频资源的重新分配,使得第一通信设备可以在预设的反馈子帧位置上向第二通信设备发送第一反馈信息,因而确保第一业务从发送到接收其对应的第一反馈信息之间的延时(即第一定时),小于第二业务从发送到接收其对应的第二反馈信息之间的延时(即第二定时),即小于传统业务的反馈延时,故,本发明实施例提供的业务反馈方法,缩短了低延时业务数据从发送到反馈的周期,满足低延时业务的低延时要求。
进一步地,上述第一定时的长度可以小于2个子帧的长度,上述第二定时的长度可以为4个子帧长度之上。可选的,上述预设的反馈子帧位置可以是第一通信设备自身确定的,也可以是第二通信设备指示第一通信设备的。具体可以参见下述两种可能的实施方式:
第一种可能的实施方式:第一通信设备根据所述第一业务的类型、所述第一业务的大小和第一映射关系,确定所述反馈子帧位置;所述第一映射关系包括所述第一时频资源与第一定时之间的对应关系,该第一定时可以用于指示上述反馈子帧位置。
具体的,第一通信设备在接收到第一业务之后,根据第一业务的类型判断第一业务为低延时业务,可选的,该第一业务可以携带自身的业务类型;之后,第一通信设备会根据第一业务的大小和预设的第一映射关系确定上述第一时频资源对应的第一定时,第一通信设备可以根据该第一定时和第一时频资源对应在第一子帧上的子帧位置确定上述发送第一反馈信息的反馈子帧位置,进而在该反馈子帧位置上发送第一反馈信息。该第一映射关系中,第一时频资源对应在第一子帧上的子帧位置不同,其对应的第一定时就不同,因而最终确定的反馈子帧位置就不同。可选的,该反馈子帧位置可以位于第一子帧上,可以位于第一子帧的下一个子帧上,还可以为位于第一子帧的下下一个子帧上,具体可以参见下述实施例的描述。
第二种可能的实施方式:第二通信设备根据所述第一业务的类型、所述第一业务的大小和第一映射关系,确定所述反馈子帧位置,并向所述第一通信设备发送所述反馈子帧位置,以指示所述第一通信设备在所述反馈子帧位置上发送所述第一反馈信息;所述第一映射关系包括所述第一时频资源与所 述第一定时之间的对应关系。
具体的,第二通信设备在向第一通信设备发送第一业务之前,会预先获知第一业务的类型和大小,当确定第一业务的类型为低延时业务时,第二通信设备会根据第一业务的大小和预设的第一映射关系确定上述第一时频资源对应的第一定时,第二通信设备可以根据该第一定时和第一时频资源对应在第一子帧上的子帧位置确定第一通信设备发送第一反馈信息的反馈子帧位置,进而将该反馈子帧位置发送给第一通信设备,以使第一通信设备在该反馈子帧位置上发送第一业务信息。该第一映射关系中,第一时频资源对应在第一子帧上的子帧位置不同,其对应的第一定时就不同,因而最终确定的反馈子帧位置就不同。可选的,该反馈子帧位置可以位于第一子帧上,可以位于第一子帧的下一个子帧上,还可以为位于第一子帧的下下一个子帧上,具体可以参见下述实施例的描述。
一般的,在上述业务反馈的场景中,可以分为两种系统,一种是未采用图4所示的新帧结构的系统,一种是采用了图4所示的新帧结构的系统。下述分别以不同的实施例对这两种系统中的业务反馈的过程进行详细的介绍。
图6为本发明提供的业务反馈方法实施例二的信令流程图。本实施例适用于未采用图4所示的新帧结构的系统,该实施例涉及UE对基站发送的第一业务进行反馈的过程,其中,第一通信设备为UE,第二通信设备为基站。为了清楚理解该方案,将第一通信设备用UE代替,将第二通信设备用基站代替。如图6所示,该方法包括:
S201:基站向UE发送第一指示信息。
其中,该第一指示信息用于向所述UE指示所述第一子帧中包括所述第一业务。可选的,基站可以在第一子帧上的PDCCH资源通过PDCCH向UE发送第一指示信息。
S202:UE接收该第一指示信息。
UE检测到该第一指示信息后,获知当前的第一子帧上包括第一业务,因此,UE等待接收该第一业务。
S203:基站在第一时频资源上向UE发送第一业务。
本实施例中,该第一时频资源可以为第一子帧中的物理下行控制信道资源,则基站发送第二业务的第二时频资源为第一子帧中的物理下行共享信道 资源(参见图7所示的第一子帧的资源位置结构示意图一);或者,该第一时频资源为第一子帧中的物理下行共享信道资源中的部分资源,则基站发送第二业务的第二时频资源为第一子帧中的物理下行共享信道资源中的剩余部分资源(参见图8所示的第一子帧的资源位置结构示意图二);或者,该第一时频资源为第一子帧中的物理下行控制信道资源的部分资源和该第一子帧中的物理下行共享信道资源中的部分资源,则基站发送第二业务的第二时频资源为第一子帧中的物理下行共享信道资源中的剩余部分资源(参见图9所示的第一子帧的资源位置结构示意图三)。
S204:UE接收该第一业务。
S205:UE在预设的反馈子帧位置上向基站发送第一反馈信息。
具体的,该预设的反馈子帧位置可以是UE自身确定的,也可以是基站确定后发送给UE的,具体的确定方式参见上述所描述的两种可能的实施方式,在此不再赘述。本实施例中,UE向基站发送第一反馈信息的反馈子帧位置为无线帧中距离第一子帧最近的且能够传输反馈信息的具有上行传输资源的子帧。例如,参见图10所示的无线帧结构示意图一,第一子帧为子帧0,第一时频资源对应在子帧0的前端部分,基站在该部分资源上发送第一业务,反馈子帧位置位于子帧2上,即UE在子帧2上发送第一反馈信息,二者之间的时间间隔为第一定时。对于第二业务,基站在子帧0的后半部分时频资源上发送,即第二时频资源对应在子帧0上的位置为子帧0的后半部分,第三时频资源对应的子帧位置位于子帧7上,第二时频资源对应的子帧位置与第三时频资源对应的子帧位置之间的时间间隔为第二定时,第二定时是传统业务的反馈机制,由图10可以看出,第一定时小于第二定时,故本发明实施例提供的业务反馈方法,大大缩短了第一业务的反馈延时。可选的,上述无线帧中距离第一子帧最近的且能够传输反馈信息的具有上行传输资源的子帧均可以作为反馈子帧位置,例如,当图10中的特殊子帧1中具备能够传输反馈信息的上行传输资源时,特殊子帧1也可以作为反馈子帧位置,当然,本实施例中所举的实际例子中,特殊子帧1上没有可以用来传输反馈信息的上行传输资源,因此,将子帧2作为反馈子帧位置。
S206:基站接收该第一反馈信息。
图11为本发明提供的业务反馈方法实施例三的流信令流程图。本实施例适用于采用了图4所示的新帧结构的系统,该实施例中的第一子帧为type1子帧。该实施例涉及UE对基站发送的第一业务进行反馈的另一具体过程,其中,第一通信设备为UE,第二通信设备为基站。为了清楚理解该方案,将第一通信设备用UE代替,将第二通信设备用基站代替。如图11所示,该方法包括:
S301:基站向UE发送第二指示信息。
其中,该第二指示信息用于向UE指示第一子帧中包括第一业务,并向UE指示在第一子帧的物理下行共享信道资源的部分时频资源上接收第一业务,实际上也就是指示UE在第一时频资源上接收第一业务(即基站会在第一时频资源上发送第一业务,相应的,UE也会在第一时频资源上接收该第一业务)。可选的,基站可以在第一子帧上的PDCCH资源上通过PDCCH向UE发送第二指示信息。
S302:UE接收该第二指示信息。
具体的,当UE接收到该第二指示信息后,可以根据该第二指示信息确定在第一时频资源上接收第一业务。
S303:基站在第一时频资源上向UE发送第一业务。
本实施例中,该第一时频资源可以为上述S301中的第一子帧的物理下行共享信道资源的部分时频资源,可以参见图12所示的第一子帧(type1)的资源位置结构示意图四。图12中,type1子帧包括物理下行控制信道资源ctrl(上述的第二指示信息可以在该部分时频资源上传输)、物理下行共享信道资源DL、保护间隔(GP)的资源GP以及用于通过PUCCH传输反馈信息和参考信号的时频资源UL。本实施例中,基站将第一子帧中的物理下行共享信道资源DL的部分资源(图12中的低延时low latency)作为第一时频资源来发送第一业务,将物理下行共享信道资源DL的剩余部分资源(DL’)作为第二时频资源来发送第二业务。
S304:UE接收该第一业务。
可选的,继续参见图12,UE也在图12所示的第一子帧的low latency部分接收第一业务。
S305:UE在预设的反馈子帧位置上向基站发送第一反馈信息。
具体的,该预设的反馈子帧位置可以是UE自身确定的,也可以是基站确定后发送给UE的,具体的确定方式参见上述所描述的两种可能的实施方式,在此不再赘述。本实施例中,UE向基站发送第一反馈信息的反馈子帧位置为第一子帧中的用于传输反馈信息的时频资源所在的位置,即上述图12所示的第一子帧的时频资源UL,也就是说,当UE完成第一业务的接收后,可以在当前第一子帧结束前利用当前第一子帧的上行传输资源向基站发送第一反馈信息,而无需在其他的子帧上去发送第一反馈信息,因此,本发明实施例,大大缩短了UE对基站的第一业务进行反馈的时间,因而降低了第一业务的反馈延时。
S306:基站接收该第一反馈信息。
图13为本发明提供的业务反馈方法实施例四的流程示意图。本实施例适用于采用了图4所示的新帧结构的系统,该实施例中的第一子帧为type2子帧。该实施例涉及UE对基站发送的第一业务进行反馈的另一具体过程,其中,第一通信设备为UE,第二通信设备为基站。为了清楚理解该方案,将第一通信设备用UE代替,将第二通信设备用基站代替。如图13所示,该方法包括:
S401:基站向UE发送第三指示信息。
其中,该第三指示信息用于向UE指示第一子帧中包括第一业务,并向UE指示在第一子帧上的用于传输反馈信息的时频资源上接收第一业务,实际上也就是指示UE在第一时频资源上接收第一业务(即基站会在第一时频资源上发送第一业务,相应的,UE也会在第一时频资源上接收该第一业务)。可选的,基站可以通过PDCCH向UE发送第三指示信息。
S402:UE接收该第三指示信息。
具体的,当UE接收到该第三指示信息后,可以根据该第三指示信息确定在第一时频资源上接收第一业务。
S403:基站在第一时频资源上向UE发送第一业务。
本实施例中,该第一时频资源可以为上述S401中的用于传输反馈信息的时频资源,可以参见图14所示的第一子帧(type2)的资源结构示意图五。图14中,type2子帧包括物理下行控制信道资源ctrl(上述的第二指示信息 可以在该部分时频资源上传输)、用于传输反馈信息和下行指示信息(例如PDCCH信息)的时频资源DL、保护间隔(GP)的资源GP以及物理上行共享信道资源UL。本实施例中,基站将第一子帧中的用于传输反馈信息的时频资源DL作为第一时频资源来发送第一业务(图14中的low latency)。
S404:UE接收该第一业务。
可选的,继续参见图14,UE也在图14所示的第一子帧的用于传输反馈信息的时频资源DL接收第一业务。
S405:UE在预设的反馈子帧位置上向基站发送第一反馈信息。
具体的,该预设的反馈子帧位置可以是UE自身确定的,也可以是基站确定后发送给UE的,具体的确定方式参见上述所描述的两种可能的实施方式,在此不再赘述。本实施例中,UE向基站发送第一反馈信息的反馈子帧位置为第一子帧中的物理上行共享信道资源所在的位置,即上述图14所示的第一子帧的物理上行共享信道资源UL,也就是说,当UE完成第一业务的接收后,可以在当前第一子帧结束前利用当前第一子帧的上行传输资源向基站发送第一反馈信息,而无需在其他的子帧上去发送第一反馈信息,因此,本发明实施例,大大缩短了UE对基站的第一业务进行反馈的时间,因而降低了第一业务的反馈延时。
S406:基站接收该第一反馈信息。
综上,上述实施例二至实施例四,均涉及的是第一通信设备为UE,第二通信设备为基站时的下行反馈过程。下面的几个实施例,均从第一通信设备为基站,第二通信设备为UE的上行反馈来进行介绍。为了能够清楚的理解本方案,下述第一通信设备均用基站来代替,下述的第二通信设备均用UE来代替。
图15为本发明提供的业务反馈方法实施例五的流程示意图。本实施例适用于未采用图4所示的新帧结构的系统,该实施例涉及基站对UE发送的第一业务进行反馈的过程。如图15所示,该方法包括:
S501:基站向UE发送第四指示信息。
其中,该第四指示信息用于指示UE在第一子帧的第一时频资源上发送第一业务。可选的,基站可以通过PDCCH向UE发送第四指示信息,该第四指示信息可以为上行调度授权(UL grant)信息。本实施例中,该第一时频资源 可以为第一子帧中的物理上行控制信道资源,则基站发送第二业务的第二时频资源为第一子帧中的物理上行共享信道资源(参见图16所示的第一子帧的资源位置结构示意图六);或者,该第一时频资源为第一子帧中的物理上行共享信道资源中的部分资源,则基站发送第二业务的第二时频资源为第一子帧中的物理上行共享信道资源中的剩余部分资源(参见图17所示的第一子帧的资源位置结构示意图七);或者,该第一时频资源为第一子帧中的物理上行控制信道资源的部分资源和该第一子帧中的物理上行共享信道资源中的部分资源,则基站发送第二业务的第二时频资源为第一子帧中的物理上行共享信道资源中的剩余部分资源(参见图18所示的第一子帧的资源位置结构示意图八)。
S502:UE接收该第四指示信息。
S503:UE根据第四指示信息,在第一时频资源上向基站发送第一业务。
S504:基站接收UE发送的第一业务。
S505:基站在预设的反馈子帧位置上向UE发送第一反馈信息。
具体的,该预设的反馈子帧位置可以是基站自身确定的,也可以是UE确定后告知给基站的,具体的确定方式参见上述所描述的两种可能的实施方式,在此不再赘述。本实施例中,基站向UE发送第一反馈信息的反馈子帧位置为无线帧中距离第一子帧最近的且能够传输反馈信息的具有下行传输资源的子帧。例如参见图19所示的无线帧结构示意图二,第一子帧为子帧7,UE根据基站的第四指示信息获知第一时频资源对应在子帧7的前端部分,则UE在该部分发送第一业务,反馈子帧位置位于子帧8上,即基站在子帧8上发送第一反馈信息,二者之间的时间间隔为第一定时。对于第二业务,UE在子帧7的后半部分时频资源上发送,即第二时频资源对应在子帧7上的位置为子帧7的后半部分,第三时频资源对应的子帧位置位于下一无线帧的子帧1上,第二时频资源对应的子帧位置与第三时频资源对应的子帧位置之间的时间间隔为第二定时,第二定时是传统业务的反馈机制,由图19可以看出,第一定时小于第二定时,故本发明实施例提供的业务反馈方法,通过对第一子帧上的时频资源重新分配,大大缩短了第一业务的反馈延时。可选的,上述无线帧中距离第一子帧最近的且能够传输反馈信息的具有下行传输资源的子帧均可以作为反馈子帧位置,例如,当图19中的子帧8中没有具备能够传输反馈 信息的下行传输资源时,子帧9也可以作为反馈子帧位置,只要确保第一定时小于第二定时即可,当然,本实施例中所举的实际例子中,子帧8上具有可以用来传输反馈信息的上行传输资源,因此,将距离子帧7最近的子帧8作为反馈子帧位置。
S506:UE接收该第一反馈信息。
图20为本发明提供的业务反馈方法实施例六的信令流程图。本实施例适用于采用了图4所示的新帧结构的系统,该实施例中的第一子帧为type1子帧。该实施例涉及基站对UE发送的第一业务进行反馈的另一具体过程。如图20所示,该方法包括:
S601:基站向UE发送第五指示信息。
其中,该第五指示信息用于向UE指示第一时频资源为第一子帧中用于传输反馈信息的时频资源,即指示UE在第一子帧上的用于传输反馈信息的时频资源上发送第一业务。可选的,基站可以通过PDCCH向UE发送第五指示信息,该第五指示信息可以为上行调度授权(UL grant)信息。
本实施例中,该第一时频资源可以参见图21所示的第一子帧(type1)的资源位置结构示意图九。图21中,type1子帧包括物理下行控制信道资源ctrl(上述的第五指示信息可以在该部分时频资源上传输)、物理下行共享信道资源DL、保护间隔(GP)的资源GP以及用于通过PUCCH传输反馈信息和参考信号的时频资源UL。本实施例中,UE将第一子帧中的时频资源UL作为第一时频资源来发送第一业务(图21中的低延时low latency)。
S602:UE接收该第五指示信息。
S603:UE在第一时频资源上向基站发送第一业务。
S604:基站接收该第一业务。
S605:基站在预设的反馈子帧位置上向UE发送第一反馈信息。
具体的,该预设的反馈子帧位置可以是基站自身确定的,也可以是UE确定后发送给基站的,具体的确定方式参见上述所描述的两种可能的实施方式,在此不再赘述。本实施例中,基站向UE发送第一反馈信息的反馈子帧位置为第一子帧的下下一个子帧,即上述图21所示的反馈子帧位置。也就是说,UE可以利用当前的第一子帧尾部的上行传输资源传输上行数据,无需单独等待 一个上行子帧来传输上行数据,这样使得基站可以在第一子帧的下下一个子帧就可以完成第一反馈信息的发送,无需像传统业务(即第二业务)一样需要等待至少4个子帧才进行反馈信息的发送,因此,本发明实施例提供的方法,通过定义第一业务的资源重用位置,大大缩短了UE对基站的第一业务进行反馈的时间,因而降低了了第一业务的反馈延时,实现了低延时的用户数据传输。
S606:UE在第一子帧的下下一个子帧的物理下行控制信道资源上接收该第一反馈信息。
图22为本发明提供的业务反馈方法实施例七的信令流程图。本实施例适用于采用了图4所示的新帧结构的系统,该实施例中的第一子帧为type2子帧。该实施例涉及基站对UE发送的第一业务进行反馈的另一具体过程。如图22所示,该方法包括:
S701:基站向UE发送第六指示信息。
其中,该第六指示信息用于向UE指示第一时频资源为所述第一子帧中物理上行共享信道资源的部分资源,即指示UE在第一子帧上的中物理上行共享信道资源的部分资源上发送第一业务。可选的,基站可以通过PDCCH向UE发送第六指示信息,该第六指示信息可以为上行调度授权(UL grant)信息。
本实施例中,该第一时频资源可以参见图23所示的第一子帧(type2)的资源位置结构示意图十。图23中,type2子帧包括物理下行控制信道资源ctrl(上述的第六指示信息可以在该部分时频资源上传输)、保护间隔(GP)的资源GP、物理上行共享信道资源UL。本实施例中,UE将第一子帧中的物理上行共享信道资源UL中的部分资源作为第一时频资源来发送第一业务(图23中的低延时low latency),UL’为剩余的物理上行共享信道资源。
S702:UE接收该第六指示信息。
S703:UE在第一时频资源上向基站发送第一业务。
S704:基站接收该第一业务。
S705:基站在预设的反馈子帧位置上向UE发送第一反馈信息。
具体的,该预设的反馈子帧位置可以是基站自身确定的,也可以是UE确定后发送给基站的,具体的确定方式参见上述所描述的两种可能的实施方式, 在此不再赘述。本实施例中,基站向UE发送第一反馈信息的反馈子帧位置为第一子帧的下下一个子帧,即上述图23所示的反馈子帧位置,第一时频资源对应在第一子帧上的子帧位置与反馈子帧位置之间的第一定时小于2个子帧的长度。因此,本发明实施例提供的方法,通过对第一子帧上的物理上行共享信道资源UL的资源复用,大大缩短了UE对基站的第一业务进行反馈的时间,因而降低了了第一业务的反馈延时。
S706:UE在第一子帧的下下一个子帧的物理下行控制信道资源上接收该第一反馈信息。
可选的,上述实施例六和实施例七中的反馈资源位置均是针对上行同步HARQ机制设计的,对于上行非同步的HARQ机制,所确定的反馈子帧位置为基站接收到第一业务后,根据基站自身的调度确定的子帧位置,也就是说,对于上行非同步的HARQ机制下基站对UE进行反馈的过程,与上述实施例六和实施例七基本相同,唯一不同之处在于基站可以根据第一时频资源与第一映射关系确定出一个子帧反馈位置,但是基站可以结合自身的实际情况,选择不在这个位置上进行反馈,而选择在其他的位置上进行第一反馈信息的发送。
图24为本发明提供的业务反馈方法实施例八的信令流程图。本实施例适用于采用了图4所示的新帧结构的系统,该实施例中的第一子帧为type2子帧。该实施例涉及基站对UE发送的第一业务进行反馈的另一具体过程。如图24所示,该方法包括:
S801:基站在第一子帧的前一子帧上向UE发送第七指示信息。
其中,该第七指示信息用于向UE指示第一时频资源为所述第一子帧中物理上行共享信道资源的部分资源,即指示UE在第一子帧上的中物理上行共享信道资源的部分资源上发送第一业务。可选的,基站可以在前一子帧的物理下行控制信道资源上通过PDCCH向UE发送第七指示信息,该第七指示信息可以为上行调度授权(UL grant)信息。
本实施例中,该第一时频资源可以参见图25所示的第一子帧(type2)的资源位置结构示意图十一。图25中,type2子帧包括物理下行控制信道资源ctrl(上述的第七指示信息在图25中的前一子帧物理下行控制信道资源 上传输)、保护间隔(GP)的资源GP、物理上行共享信道资源UL。本实施例中,UE将第一子帧中的物理上行共享信道资源UL中的部分资源作为第一时频资源来发送第一业务(图25中的低延时low latency),UL’为剩余的物理上行共享信道资源。
S802:UE接收该第七指示信息。
S803:UE在第一时频资源上向基站发送第一业务。
S804:基站接收该第一业务。
S805:基站在预设的反馈子帧位置上向UE发送第一反馈信息。
具体的,该预设的反馈子帧位置可以是基站自身确定的,也可以是UE确定后发送给基站的,具体的确定方式参见上述所描述的两种可能的实施方式,在此不再赘述。本实施例中,基站向UE发送第一反馈信息的反馈子帧位置为第一子帧的下一个子帧,即上述图25所示的反馈子帧位置,第一时频资源对应在第一子帧上的子帧位置与反馈子帧位置之间的第一定时小于2个子帧的长度。因此,本发明实施例提供的方法,通过对第一子帧上的物理上行共享信道资源UL的资源复用,大大缩短了UE对基站的第一业务进行反馈的时间,因而降低了了第一业务的反馈延时。
S806:UE在第一子帧的下一个子帧的物理下行控制信道资源上接收该第一反馈信息。
可选的,上述实施例八中的反馈资源位置是针对上行同步HARQ机制设计的,对于上行非同步的HARQ机制,所确定的反馈子帧位置为基站接收到第一业务后,根据基站自身的调度确定的子帧位置,也就是说,对于上行非同步的HARQ机制下基站对UE进行反馈的过程,与上述实施例八基本相同,唯一不同之处在于基站可以根据第一时频资源与第一映射关系确定出一个子帧反馈位置,但是基站可以结合自身的实际情况,选择不在这个位置上进行反馈,而选择在其他的位置上进行第一反馈信息的发送。
本发明实施例提供的业务反馈方法,第二通信设备在第一时频资源上向第一通信设备发送第一业务,使得第一通信设备在接收到第一业务后有足够的时间对第一业务进行处理,通过对第一子帧的时频资源的重新分配,使得第一通信设备可以在预设的反馈子帧位置上向第二通信设备发送第一反馈信息,因而确保第一业务从发送到接收其对应的第一反馈信息之 间的延时(即第一定时),小于第二业务从发送到接收其对应的第二反馈信息之间的延时(即第二定时),即小于传统业务的反馈延时,故,本发明实施例提供的业务反馈方法,缩短了低延时业务数据从发送到反馈的周期,满足低延时业务的低延时要求。
