本公开涉及通信技术领域,尤其涉及一种非授权频段反馈信息传输方法、装置及存储介质。
背景技术

本公开实施例提供的反馈方法可应用于图1所示的无线通信系统中。参阅图1所示,该无线通信系统中包括终端和网络设备。终端通过无线资源与网络设备相连接,并进行数据的发送与接收。
可以理解的是,图1所示的无线通信系统仅是进行示意性说明,无线通信系统中还可包括其它网络设备,例如还可以包括核心网设备、无线中继设备和无线回传设备等,在图1中未画出。本公开实施例对该无线通信系统中包括的网络设备数量和终端数量不做限定。
进一步可以理解的是,本公开实施例的无线通信系统,是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术,例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access,WCDMA)、时分多址(time division multiple access,TDMA)、频分多址(frequency division multiple access,FDMA)、正交频分多址(orthogonal frequency-division multiple access,OFDMA)、单载波频分多址 (single Carrier FDMA,SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文:generation)网络、3G网络、4G网络或者未来演进网络,如5G网络,5G网络也可称为是新无线网络(New Radio,NR)。为了方便描述,本公开有时会将无线通信网络简称为网络。
进一步的,本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是:基站、演进型基站(evolved node B,基站)、家庭基站、无线保真(wireless fidelity,WIFI)系统中的接入点(access point,AP)、无线中继节点、无线回传节点、传输点(transmission point,TP)或者发送接收点(transmission and reception point,TRP)等,还可以为NR系统中的gNB,或者,还可以是构成基站的组件或一部分设备等。当为车联网(V2X)通信系统时,网络设备还可以是车载设备。应理解,本公开的实施例中,对网络设备所采用的具体技术和具体设备形态不做限定。
进一步的,本公开中涉及的终端,也可以称为终端设备、用户设备(User Equipment,UE)、移动台(Mobile Station,MS)、移动终端(Mobile Terminal,MT)等,是一种向用户提供语音和/或数据连通性的设备,例如,终端可以是具有无线连接功能的手持式设备、车载设备等。目前,一些终端的举例为:智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer,PPC)、掌上电脑、个人数字助理(Personal Digital Assistant,PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外,当为车联网(V2X)通信系统时,终端设备还可以是车载设备。应理解,本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
图1中,终端与网络设备进行通信,终端向网络设备发送数据的过程可称为上行传输。网络设备向终端发送数据的过程可称为下行传输。终端和网络设备进行上行传输和下行传输过程中,采用HARQ反馈技术,以保证传输的可靠性。
在R16NR-U的标准讨论和设计中,对于HARQ-ACK信息的反馈,设计和通过了2种反馈方式。一种是增强动态HARQ-ACK反馈方式,其与NR Release 15的动态码本(dynamic HARQ-ACK codebook)反馈基本相同。调度物理下行共享信道(Physical Downlink Shared channel,PDSCH)的下行控制信息(downlink control information,DCI)通过PUCCH资源指示(PUCCH resource indicator,PRI)/K1/发射功率控制(Transmit Power Control,TPC)等域指定承载该PDSCH的HARQ-ACK信息的物理上行控制信道(Physical Uplink Control Channel,PUCCH)资源。其中,K1表示PDSCH所在slot与对应的HARQ-ACK 信息所在的slot之间间隔的slot数量。DCI中有1bit用于指示该DCI所调度的PDSCH的组号,不同组的PDSCH的HARQ-ACK对应不同的HARQ-ACK码本。DCI所调度的PDSCH包括2组PDSCH。增强动态HARQ-ACK反馈方式可以为一个或者多个调度的PDSCH指定PUCCH资源,而不会产生额外的信息传输开销(overhead),因而适合用于要对单个PDSCH进行及时快速反馈的情况。
另一种是one-shot HARQ-ACK反馈方式。一次性HARQ-ACK反馈是一种半静态的反馈方式,终端需要一次性反馈所有配置的HARQ进程(包括实际调度了的HARQ进程,以及没有调度的HARQ进程)的HARQ-ACK信息。例如,假如网络设备为终端配置了16个HARQ进程,如果终端被触发反馈one-shot HARQ-ACK信息,则终端需要反馈所有16个进程的HARQ-ACK信息。如果存在没有被调度有的HARQ进程,则终端将反馈该进程上一次被使用时对应的HARQ-ACK信息,或者反馈一个默认值(例如非确认(NACK))。其中,可以由网络设备配置反馈上一次被使用时对应的HARQ-ACK信息,或者反馈默认值。对于配置了one-shot HARQ-ACK反馈方式的终端,发送给终端调度PDSCH的DCI中有1bit的信息域用于判断是否触发one-shot HARQ-ACK反馈。
One-shot HARQ-ACK码本包含的对应的PDSCH为承载该One-shot HARQ-ACK码本的PUCCH信道之前特定时长T(用于PDSCH解调和HARQ-ACK准备的最短时间,在3gpp TS 38.214中定义)之前的所有未反馈的PDSCH。如图2所示。假定在某种配置条件下,T=4.5个符号。承载该One-shot HARQ-ACK码本的PUCCH信道在时隙2(slot2)的符号2/3上。那么符号2的T时长之前的尚未反馈HARQ-ACK的PDSCH,例如图中的PDSCH1/2/3,都会在该one-shot码本中反馈HARQ-ACK信息。One-shot HARQ-ACK反馈方式由于需要一次反馈所有HARQ进程的,所以适用于对多个PDSCH(小于或等于总的HARQ进程数)集中一起进行反馈的情况,否则会出现较大的信息开销。
在5G NR中,终端并发支持高可靠低时延(Ultra Reliable Low Latency Communications,URLLC)业务类型和移动带宽增强(Enhance Mobile Broadband,eMBB)业务类型。URLLC业务是要求高可靠性和低时延的业务类型。eMBB业务并不要求那么高的可靠性和低时延,但会要求较大的数据传输速率。
对于URLLC业务,希望能够尽快的传输其HARQ-ACK信息,降低PDSCH到HARQ-ACK反馈之间的时延,以降低整体的数据传输时延。对于eMBB业务,其HARQ-ACK反馈并不严格要求低时延,可以将时域上前后多个PDSCH的HARQ-ACK信息集中一起传输,以提高资源利用效率。
对于同一个终端来说,同时有URLLC业务和eMBB业务是一种常见的场景。为了支持两种业务的灵活复用,HARQ-ACK码本分为2种不同的优先级,高优先级的码本能获得优先传输。例如当两个承载不同优先的HARQ-ACK信息的PUCCH信道在时域重叠时,传输高优先级的HARQ-ACK信息,丢弃低优先级的HARQ-ACK信息。在当前即将进行的R17标准讨论中,将研究如何在非授权频谱上部署URLLC业务。当URLLC业务部署在非授权频段上时,为了支持与eMBB业务的灵活复用,应该同样支持2种不同优先级的HARQ-ACK码本。
然而,已有NR-U协议中约定,如果终端被调度了在同一个slot中进行one-shot HARQ-ACK反馈和enhanced dynamic HARQ-ACK反馈,那么终端将只反馈one-shot HARQ-ACK码本,不反馈enhanced dynamic HARQ-ACK码本。如果在非授权频段上传输URLLC业务,对于触发了one-shot HARQ-ACK码本之后又突发的URLLC业务的PDSCH,应该如何进行HARQ-ACK反馈,是需要解决的问题。
本公开实施例提供一种NR-U中反馈信息的传输方法,终端接收到HARQ-ACK的优先级被指示为高优先级的PDSCH时,且该PDSCH的HARQ-ACK反馈PUCCH资源与其他PDSCH的one-shot HARQ-ACK在同一个时域资源单元内,则在该时域资源单元内发送该PDSCH的HARQ-ACK信息,以实现在在同一时域资源单元内区分PDSCH的HARQ-ACK信息优先级,进行HARQ-ACK信息的传输。
本公开实施例以下为描述方便,将HARQ-ACK信息优先级被指定为高优先级的PDSCH称为第一PDSCH。将one-shot HARQ-ACK码本对应的PDSCH称为第二PDSCH。
图3是根据一示例性实施例示出的一种NR-U中反馈信息传输方法的流程图,如图3所示,反馈信息传输方法用于终端中,包括以下步骤。
在步骤S11中,确定第一PDSCH的HARQ-ACK信息。
在步骤S12中,响应于反馈第一PDSCH的HARQ-ACK信息的PUCCH资源与反馈一个或多个第二PDSCH的one-shot HARQ-ACK的PUCCH资源在同一时域资源单元内,在该时域资源单元内发送第一PDSCH的HARQ-ACK信息。
本公开实施例中,第一PDSCH可以是动态调度的PDSCH,也可以是半静态调度的PDSCH(Semi-Persistent Scheduling,SPS PDSCH)。
更进一步的,本公开实施例中第一PDSCH的HARQ-ACK信息优先级高于第二PDSCH的one-shot HARQ-ACK信息优先级。其中,本公开实施例中第一PDSCH的HARQ-ACK信息可以被指示为高优先级。第一PDSCH的HARQ-ACK信息被指示为高优先级,且反 馈第一PDSCH的HARQ-ACK信息的PUCCH资源与反馈一个或多个第二PDSCH的one-shot HARQ-ACK的PUCCH资源在同一时域资源单元内,则在调度一个或多个第二PDSCH的one-shot HARQ-ACK的PUCCH资源的时域资源单元内发送第一PDSCH的HARQ-ACK信息。
其中,针对动态调度的第一PDSCH,第一PDSCH的HARQ-ACK信息的优先级可以由DCI指示。例如对于增强动态HARQ-ACK反馈方式,重用上述DCI中的1bit指示PDSCH组号(PDSCH group ID),除指示对应的PDSCH的组号外,还附带HARQ-ACK码本的优先级信息。例如当PDSCH group ID=1,表示其对应的HARQ-ACK为高优先级。当PDSCH group ID=0,表示其对应的HARQ-ACK为低优先级。也可以使用新的一个信息域bit,用于区分该DCI所调度的PDSCH所对应的HARQ-ACK码本的优先级。
针对半静态调度的第一PDSCH,第一PDSCH的HARQ-ACK信息的优先级可以在(Radio Resource Control,RRC)层的配置信息中配置。
本公开实施例中,第一PDSCH被调度时,通常会指示反馈第一PDSCH的HARQ-ACK信息的PUCCH资源。其中,针对动态调度的第一PDSCH,反馈第一PDSCH的HARQ-ACK信息的PUCCH资源可以由DCI指示。例如,反馈第一PDSCH的HARQ-ACK信息的PUCCH资源可以由指示第一PDSCH的HARQ-ACK信息的优先级的DCI指示。针对半静态调度的第一PDSCH,反馈第一PDSCH的HARQ-ACK信息的PUCCH资源可以由RRC层的配置信息配置并由激活DCI指示。其中,激活DCI可以理解为是用于激活半静态调度PDSCH的DCI。
本公开实施例中一种方式中,发送第一PDSCH的HARQ-ACK信息时,在DCI指示的PUCCH资源上发送第一PDSCH的HARQ-ACK信息。
其中,针对工作在NR-U中的终端,网络设备可以为终端配置支持增强动态HARQ-ACK反馈方式,并配置支持one-shot HARQ-ACK反馈方式。其中,若反馈第一PDSCH的HARQ-ACK信息的PUCCH资源与反馈一个或多个第二PDSCH的one-shot HARQ-ACK的PUCCH资源在同一时域资源单元内,则终端在该时域资源单元内发送第一PDSCH的HARQ-ACK信息。例如,使用增强动态反馈码本在DCI指示的PUCCH资源,发送第一PDSCH的HARQ-ACK信息。
可以理解的是,本公开实施例中并不限定第一PDSCH的HARQ-ACK信息的反馈方式必须采用增强动态反馈方式,也可以是采用诸如one-shot HARQ-ACK方式。
本公开实施例中上述涉及的时域资源单元可以是slot,也可以是子时隙(subslot)。本 公开实施例以下以slot为例进行说明,可以理解的是所举示例中slot也可以是subslot,本公开实施例不再重复一一赘述。
本公开实施例中,第一PDSCH对应于低时延业务,第二PDSCH对应于高时延业务。其中低时延业务和高时延业务是相对而言的,即第一PDSCH对应的业务对于时延的要求,高于第一PDSCH对应的业务。例如:第一PDSCH对应的业务为URLLC业务,第二PDSCH对应的业务为eMBB业务。当然,这只是举例说明,本公开实施例中并不对业务的类型进行限制。
本公开实施例中,所述第一PDSCH的HARQ-ACK信息,优先级高于第二PDSCHHARQ-ACK信息。例如:第一PDSCH对应的业务为URLLC业务,第二PDSCH对应的业务为eMBB业务;当然,这只是举例说明,本公开实施例中并不对业务的类型进行限制。
本公开实施例中,在非授权频段,终端可以确定第一PDSCH的HARQ-ACK反馈信息和确定第二PDSCH的HARQ-ACK反馈信息。可以理解的是,确定第一PDSCH的HARQ-ACK反馈信息和确定第二PDSCH的HARQ-ACK反馈信息并无先后顺序的限定。终端在调度一个或多个第二PDSCH的one-shot HARQ-ACK的PUCCH资源的时域资源单元内发送一个或多个第二PDSCH的one-shot HARQ-ACK信息以及第一PDSCH的HARQ-ACK信息。
本公开一示例中,在非授权频段,针对同一个slot被触发了one-shot HARQ-ACK反馈和enhanced dynamic HARQ-ACK反馈的情况。如果终端被配置了增强动态HARQ-ACK反馈和one-shot HARQ-ACK反馈,针对下述情况可以理解为是反馈第一PDSCH的HARQ-ACK信息的PUCCH资源与反馈一个或多个第二PDSCH的one-shot HARQ-ACK的PUCCH资源在同一时域资源单元内,则终端在在该时域资源单元内发送第一PDSCH的HARQ-ACK信息的情况。终端被触发了在一个slot中针对一个或多个第二PDSCH进行one-shot HARQ-ACK反馈之后,又收到一个PDSCH(第一PDSCH);其中该第一PDSCH的HARQ-ACK的优先级为高优先级,或第一PDSCH对时延的要求更高,或基于标准中对于第一PDSCH和第二PDSCH的设定;且该第一PDSCH的HARQ-ACK反馈PUCCH资源也在同一个slot中,但第一PDSCH的HARQ-ACK信息无法承载在该one-shot HARQ-ACK码本中,则终端将使用增强动态HARQ-ACK码本在被指示的PUCCH资源上反馈该第一PDSCH的HARQ-ACK信息。
本公开实施例中,第一PDSCH的HARQ-ACK信息无法承载在该one-shot HARQ-ACK 码本中,可以理解为是第一PDSCH的结束时间,与承载one-shot HARQ-ACK码本的PUCCH的起始时间之间的时间差小于第一时长。在本公开的所有实施方式中,第一时长为协议规定的;或,第一时长为UE确定并上报给网络设备的;或,第一时长为网络设备确定并发送给终端的;或,第一时长为网络设备与终端协商确定的;或,第一时长为终端与网络设备协商确定的。在本公开的所有实施例中,第一时长大于或等于解调PDSCH并产生HARQ-ACK信息的最小时长。
图4示出了本公开一示例性实施例中在同一slot中反馈one-shot HARQ-ACK码本和增强动态HARQ-ACK码本的示意图。参阅图4所示,终端在PDSCH3的调度DCI中触发了在slot2的PUCCH1上进行PDSCH1、PDSCH2和PDSCH3的one-shot HARQ-ACK反馈。但是终端在之后又收到了PDSCH 4,PDSCH 4的HARQ-ACK优先传输(PDSCH 4的HARQ-ACK的优先级为高优先级,或PDSCH 4对时延的要求更高,或基于标准中对于PDSCH 4与PDSCH1、PDSCH2、PDSCH3的设定),承载其HARQ-ACK的PUCCH资源被指示在slot2的PUCCH2上。由于PDSCH4不能满足特定时长T(图示中以T=4.5个符号为例进行说明)的限制,也即终端不能将PDSCH 4的HARQ-ACK反馈信息承载到PUCCH 1的one-shot HARQ-ACK码本中,但PDSCH 4的HARQ-ACK优先级指示为高,也即终端需要尽快对PDSCH 4进行HARQ-ACK反馈。应用本公开实施例提供的反馈信息传输方法,终端将在slot 2的PUCCH 2上,将PDSCH 4的HARQ-ACK信息承载在增强动态HARQ-ACK码本上反馈给网络设备。
本公开实施例中,第一PDSCH由网络设备向终端调度发送,终端将第一PDSCH的HARQ-ACK信息承载在增强动态HARQ-ACK码本上反馈给网络设备。网络设备接收终端反馈的第一PDSCH的HARQ-ACK信息。
图5是根据一示例性实施例示出的一种NR-U中反馈信息传输方法的流程图,如图5所示,反馈信息传输方法用于网络设备中,包括以下步骤。
在步骤S21中,发送第一PDSCH。
可以理解的是,本公开实施例中网络设备也会发送第二PDSCH。在本公开的所有实施例中,发送第一PDSCH和发送第二PDSCH之间没有先后顺序的限制;即:发送第一PDSCH可以在发送第二PDSCH之前,也可以是发送第一PDSCH在发送第二PDSCH之后,还可以是发送第一PDSCH并同时发送第二PDSCH。
在步骤S22中,响应于反馈第一PDSCH的HARQ-ACK信息的PUCCH资源与反馈一个或多个第二PDSCH的one-shot HARQ-ACK的PUCCH资源在同一时域资源单元内,在 该时域资源单元内接收第一PDSCH的HARQ-ACK信息。
本公开实施例中,网络设备使用增强动态HARQ-ACK码本在被指示的PUCCH资源上接收第一PDSCH的HARQ-ACK信息。
其中,第一PDSCH的结束时间,与承载one-shot HARQ-ACK码本的PUCCH的起始时间之间的时间差小于第一时长。在本公开的所有实施方式中,第一时长为协议规定的;或,第一时长为UE确定并上报给网络设备的;或,第一时长为网络设备确定并发送给UE的;或,第一时长为基站与UE协商确定的;或,第一时长为UE与网络设备协商确定的。在本公开的所有实施例中,第一时长大于或等于解调PDSCH并产生HARQ-ACK信息的最小时长。
本公开实施例中,所述第一PDSCH对应于低时延业务,所述第二PDSCH对应于高时延业务。其中低时延业务和高时延业务是相对而言的,即第一PDSCH对应的业务对于时延的要求,高于第一PDSCH对应的业务。例如:第一PDSCH对应的业务为URLLC业务,第二PDSCH对应的业务为eMBB业务。
本公开实施例中,所述第一PDSCH的HARQ-ACK信息,优先级高于第二PDSCHHARQ-ACK信息。例如:第一PDSCH对应的业务为URLLC业务,第二PDSCH对应的业务为eMBB业务。
可以理解的是,本公开实施例提供的NR-U的反馈信息传输方法可以应用于终端与网络设备交互的过程中。对于终端和网络设备交互实现在NR-U上反馈信息传输的过程可参阅上述实施例相关描述,在此不再赘述。
