Description

信息报告方法、装置、设备及存储介质 技术领域
本申请实施例涉及通信技术领域,特别涉及一种信息报告方法、装置、设备及存储介质。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案,并不构成对本申请实施例提供的技术方案的限定,本领域普通技术人员可知,随着网络架构的演变和新业务场景的出现,本申请实施例提供的技术方案对于类似的技术问题,同样适用。
首先,对本申请实施例中涉及的一些名词和相关技术等进行简单地介绍。
1、Type-1 HARQ-ACK码本和Type-2 HARQ-ACK码本
NR系统支持两种HARQ(Hybrid Automatic Repeat Request,混合自动重传请求)-ACK(Acknowledgement,肯定确认)码本:Type-1 HARQ-ACK码本(类型1 HARQ-ACK码本)和Type-2 HARQ-ACK码本(类型2 HARQ-ACK码本)。
Type-1 HARQ-ACK码本:采用半静态的方式确定PDSCH对应的HARQ-ACK信息的比特数。也即:通过通信协议预定义,或者,通过网络设备的半静态配置信息(如time domain resource allocation table(时域资源分配表)、K1 set(第一时隙计时集合)等),来确定可用于传输PDSCH的下行资源(即候选PDSCH接收机会),并为半静态确定的每个候选PDSCH接收机会预留HARQ-ACK反馈比特。该方法的优点在于可以避免因为终端设备漏检PDCCH(Physical Downlink Control Channel,物理下行控制信道)而造成的终端设备与网络设备对于HARQ-ACK码本大小理解不一致,避免网络设备无法正确解调终端设备发送的HARQ-ACK码本。该方法的缺点在于反馈开销较大,也即,候选PDSCH接收机会并不一定真正地有PDSCH传输。
Type-2 HARQ-ACK码本:采用动态的方式确定HARQ-ACK码本的比特数。也即,终端设备根据接收 到的DCI,确定实际调度的PDSCH和/或SPS(Semi-Persistent Scheduling,半静态调度)PDSCH所需要的HARQ-ACK反馈比特数。可选地,为了应对除最后一个PDCCH之外的其余PDCCH漏检的问题,引入了DAI(Downlink Assignment Index,下行分配索引)指示。请参考图1,其示出了本申请一个实施例提供的DAI指示的示意图。如图1所示,网络设备发送PDSCH 1~PDSCH 4,分别对应的DAI=1~4,终端设备由于漏检调度PDSCH 3的PDCCH,导致PDSCH 3并未被接收,但是终端设备接收到PDSCH 4,且对应的DAI=4,则终端设备可以判断出其漏检了PDSCH 3,则反馈4比特HARQ-ACK给网络设备。
2、信道状态信息(CSI)
CSI是指用来估计通信链路的信道特性的信息。网络设备可以基于终端设备上报的CSI确定下行数据的调制方案、信道编码码率等,以提高下行数据的传输可靠性和传输效率。
在NR系统的Rel-15以及Rel-16中,CSI是基于终端设备对CSI-RS资源的测量获取并上报至网络设备的。在Rel-15和Rel-16中,CSI的上报依据时域特征划分为:周期性上报CSI、半持续性上报CSI、非周期性上报CSI。
周期性上报CSI:网络设备通过RRC(Radio Resource Control,无线资源控制)信令为终端设备配置上报CSI的周期和偏移,终端设备接收到该RRC信令之后,在网络设备配置的PUCCH(Physical Uplink Control Channel,物理上行控制信道)上周期性地上报CSI。
半持续性上报CSI:在终端设备通过PUCCH半持续性地上报CSI的情况下,网络设备通过MAC(Medium Access Control,媒体接入控制)CE(Control Element,控制单元)信令激活/去激活CSI的上报,在MAC CE信令激活CSI的上报后,终端设备在PUCCH上周期性地上报CSI;在终端设备通过PUSCH(Physical Uplink Shared Channel,物理上行共享信道)半持续性地上报CSI的情况下,网络设备通过DCI(Downlink Control Information,下行控制信息)激活/去激活CSI的上报,在DCI激活CSI的上报后,终端设备在PUSCH上周期性地上报CSI。
非周期性上报CSI:网络设备通过DCI触发CSI的上报,终端设备接收到该DCI之后,在该DCI指示的PUSCH上仅上报一次CSI。
在一些实现中,用于在slot n(时隙n)上报CSI的信道/干扰测量资源不能晚于CSI参考资源时隙n-n CSI-ref。对于周期性和半持续性地上报CSI,当只配置一个CSI-RS用于信道测量资源时,n CSI-ref需要大于
Figure PCTCN2021083304-appb-000001
对于非周期性地上报CSI,n CSI-ref需要大于CSI计算时间,其中,CSI计算时间远大于PDSCH解码时间。
为了同时满足URLLC业务的低时延与高可靠这两个特性(例如,保证URLLC业务在时延允许范围内的传输次数可以达到可靠性需求),则需要终端设备上报更加准确的反映信道质量的信道状态信息,以辅助网络设备更好地进行初传和/或重传调度。在一个示例中,可以通过以下方式实现上报更为准确的信道状态信息。
(1)将周期性/半持续性地上报CSI的周期配置地非常短;
(2)使用DCI触发非周期地上报CSI。
针对方式(1),需要网络设备高密度地发送CSI-RS资源,才能够获得快速更新的信道状态信息,这一方面加大了系统的参考信号(CSI-RS资源)开销,另一方面增加了终端设备的测量与计算开销。与此同时,由于受到CSI测量时间的影响,终端设备上报的CSI需要基于CSI参考资源之前的CSI-RS测量得到,对于在上行时隙n上报的周期性/半持续性CSI,CSI参考资源最早为时隙n-4传输的CSI-RS(假设:UL(Uplink,上行链路)和DL(Downlink,下行链路)具有相同的子载波间隔,且对信道测量只配置了一个CSI-RS资源),而终端设备受到的干扰情况受到邻小区调度的影响很大,由于测量时间很长,终端设备在上报CSI时可能受到的干扰已经发生了变化,导致CSI不准确。
针对方式(2),网络设备需要发送DCI来触发CSI-RS的发送以及CSI的上报,一方面,用于触发CSI上报的DCI只能是调度PUSCH的DCI(UL DCI),而终端设备可能上下行业务不对称,并没有上行业务需求,这种情况下,为了触发CSI的上报,就会浪费UL DCI;另一方面,对于非周期性地上报CSI,终端设备从收到UL DCI到发送CSI的处理时间也很长,对于时延紧急的业务,如果初传错误,且时延需求无法容忍CSI上报,网络设备只能使用非常保守的MCS(Modulation and Coding Scheme,调制与编码策略)进行调度,导致系统的传输效率降低。
为满足URLLC业务的低时延与高可靠性的需求,且同时提升系统传输效率,Rel-17中提出了基于PDSCH的解调和/或测量的信道状态信息。基于PDSCH的解调和/或测量来获取信道状态信息不仅可以节约CSI-RS资源,还可以降低终端设备的计算功耗与处理时延,能够较好地满足URLLC业务的需求。
然而,针对基于PDSCH的解调和/或测量的信道状态信息如何上报至网络设备,Rel-17中尚未提及和 讨论。基于此,本申请实施例提供了一种信息报告方法,可用于解决上述技术问题。下面,将结合几个实施例对本申请的技术方案进行介绍说明。
需要说明的一点是,本申请实施例中所述的“终端设备向网络设备上报CSI”,又可以称为“终端设备向网络设备报告CSI”,还可以称为“终端设备向网络设备反馈CSI”。应理解,这些表述具有相同的含义,可以彼此替换。
请参考图2,其示出了本申请一个实施例提供的通信系统的示意图。该通信系统可以包括:终端设备10和网络设备20。
终端设备10的数量通常为多个,每一个网络设备20所管理的小区内可以分布一个或多个终端设备10。终端设备10可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备,以及各种形式的用户设备(User Equipment,UE),移动台(Mobile Station,MS)等等。为方便描述,本申请实施例中,上面提到的设备统称为终端设备。
网络设备20是一种部署在接入网中用以为终端设备10提供无线通信功能的装置。网络设备20可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备网络设备功能的设备的名称可能会有所不同,例如在5G(5th-Generation,第五代移动通信技术)NR系统中,称为gNodeB或者gNB。随着通信技术的演进,“网络设备”这一名称可能会变化。为方便描述,本申请实施例中,上述为终端设备10提供无线通信功能的装置统称为网络设备。
可选地,网络设备20与终端设备10之间通过某种空口技术互相通信,例如Uu接口。
本申请实施例中的“5G NR系统”也可以称为5G系统或者NR系统,但本领域技术人员可以理解其含义。
应理解,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频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)系统、先进的长期演进(Advanced Long Term Evolution,LTE-A)系统、NR系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to Unlicensed spectrum,LTE-U)系统、NR-U(New Radio-Unlicensed,非授权频段上的NR)系统、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。
请参考图3,其示出了本申请一个实施例提供的信息报告方法的流程图,该方法可以应用于上述图2所示的通信系统中。该方法可以包括如下步骤中的至少部分步骤。
步骤310,终端设备在满足第一报告条件的情况下,向网络设备报告第一信息,第一信息是基于PDSCH确定的。
第一信息用于估计通信链路的信道质量和/或信道特性,本申请实施例中,第一信息是基于PDSCH确定的。可选地,第一信息包括基于PDSCH的解调和/或测量得到的信道状态信息。应理解,“第一信息”这一名称可能会发生变化,例如,“第一信息”也可以称为“信道状态信息”,或者称为“新型信道状态信息”,或者称为“case-2 new reporting(情况2新型报告)”,或者称为“case-2 reporting(情况2报告)”。为了便于描述,本申请实施例将基于PDSCH确定的、用于估计通信链路的信道质量和/或信道特性的信息,统称为“第一信息”。
终端设备可以向网络设备报告第一信息,以向网络设备指示通信链路的信道质量和/或信道特性,从而为网络设备进行下行传输等提供参考。可选地,终端设备通过PUCCH资源向网络设备报告第一信息。本申请实施例中,终端设备在满足第一报告条件的情况下,向网络设备报告第一信息。该第一报告条件可以是通信协议定义的,也可以是网络设备配置(或称为“指示”)的,例如,网络设备通过高层信令配置第一报告条件,可选地,高层信令包括以下至少一项:SIB(System Information Block,系统消息块)、RRC、MAC。本申请实施例对第一报告条件的具体内容不作限定,可选地,第一报告条件包括:终端设备接收到特定的DCI、终端设备接收到的DCI中的某一DAI满足特定的条件、终端设备所在的时间单元满足特定的条件等,有关第一报告条件的其它介绍说明,请参见下述实施例,此处不多赘述。
需要说明的一点是,本申请实施例对终端设备确定第一信息的时机不作限定。在一个示例中,终端设备在满足第一报告条件之前确定第一信息,并在满足第一报告条件时或在满足第一报告条件之后向网络设备报告第一信息。在另一个示例中,终端设备在满足第一报告条件时或在满足第一报告条件之后,确定第一信息并向网络设备报告第一信息。
终端设备在向网络设备报告第一信息时,可以将第一信息作为单独的上行信息报告至网络设备,此时,终端设备可以将第一信息与其它上行信息(如HARQ-ACK信息)同时报告至网络设备,也可以不与其它上行信息(如HARQ-ACK信息)同时报告至网络设备;或者,终端设备也可以将第一信息与其它的上行 信息(如HARQ-ACK信息)组合在一起上报至网络设备,本申请实施例对第一信息的报告方式不作限定。
在一种可能的实施方式中,终端设备将第一信息与HARQ-ACK信息组合在一起上报至网络设备,基于此,上述终端设备向网络设备报告第一信息,包括:终端设备基于HARQ-ACK信息和第一信息,生成第一码本;终端设备向网络设备发送第一码本。本申请实施例对第一码本的具体生成方式不作限定,可选地,终端设备基于HARQ-ACK信息和第一信息,分别生成子码本,并组合子码本得到第一码本;或者,终端设备基于HARQ-ACK信息生成子码本,并将第一信息添加至子码本中得到第一码本。下面,针对第一码本的几种示例性生成方式进行介绍说明。

一方面,终端设备可以按照相关技术中生成HARQ-ACK码本的方式,基于HARQ-ACK信息生成第一子码本,该第一子码本包括O ACK比特的HARQ-ACK信息。另一方面,终端设备基于第一信息生成第二子码本,假设每个第一信息的比特数为S(S为正数),则第二子码本的比特数为T*S(T为正数),其中,T的取值确定方式请参见下述实施例,此处不多赘述。终端设备组合第一子码本和第二子码本,即可得到第一码本。可选地,终端设备将第一子码本添加至第二子码本之后得到第一码本;或者,终端设备将第二子码本添加至第一子码本之后得到第一码本。
本申请实施例对T的取值确定方式不作限定。终端设备在本次向网络设备报告第一信息与上次向网络设备报告第一信息之间,接收到来自于网络设备的至少一个DCI,每个DCI中包括至少一个DAI,该至少一个DAI包括第一DAI,可选地,该第一DAI是指至少一个DAI中的Counter DAI(计数DAI)。可选地,T为至少一个DCI中包括的第一DAI的取值为第一数值的次数,该第一数值可以是通信协议定义的,也可以是网络设备配置的,例如,网络设备通过高层信令配置第一数值,可选地,高层信令包括以下至少一项:SIB、RRC、MAC;或者,T为至少一个DCI中包括的第一DAI的取值满足如下条件的次数:mod(4*j+Z,X)=Y,其中,mod(4*j+Z,X)用于求取(4*j+Z)除以X的余数;j(j为正数)为至少一个DCI中包括的第一DAI的取值达到最大值的次数;Z(Z为正数)为第一DAI的取值;X(X为正数)为第一数量阈值,该第一数量阈值可以是通信协议定义的,也可以是网络设备配置的,例如,网络设备通过高层信令配置第一数量阈值,可选地,高层信令包括以下至少一项:SIB、RRC、MAC;Y(Y为正数)为第一参考值,该第一参考值可以是通信协议定义的,也可以是网络设备配置的,例如,网络设备通过高层信令配置第一参考值,可选地,高层信令包括以下至少一项:SIB、RRC、MAC。

在另一个示例中,上述终端设备基于HARQ-ACK信息和第一信息,生成第一码本,包括:终端设备基于HARQ-ACK信息,生成第一子码本;将至少一个DCI中包括的第一DAI中,满足第一取值条件的第一DAI对应的第一信息,添加至第一子码本中与满足第一取值条件的第一DAI对应的HARQ-ACK比特之后,得到第一码本。
终端设备在生成第一码本的过程中,可以判断至少一个DAI中分别包括的第一DAI是否满足第一取值条件。该第一取值条件包括第一DAI的取值为第一数值;或者,第一DAI的取值满足如下条件:mod(4*j+Z,X)=Y。若第一DAI的取值满足第一取值条件,则终端设备在第一子码本中与该第一DAI对应的HARQ-ACK比特之后,添加该第一DAI对应的第一信息,进而得到第一码本。
示例性地,假设网络设备向终端设备发送了6个DCI,分别为DCI 1至DCI 6,且这6个DCI中分别包括的第一DAI(C-DAI)为:1、2、3、4、1、2。在该示例中,还假设终端设备接收到这6个DCI中的5个DCI,且这5个DCI分别包括的C-DAI为:1、2、3、4、2,则终端设备生成的第一子码本包括6个比特的HARQ-ACK信息,分别为b 1、b 2、b 3、b 4、b 5、b 6,其中,b 5对应的HARQ-ACK信息为NACK。
在该示例中,可选地,还假设第一DAI需要满足的第一取值条件为第一DAI的取值为1,那么,终端设备针对C-DAI=1的DCI需要向网络设备报告第一信息。其中,DCI 1(终端设备接收到)中包括的第一DAI的取值为1,DCI 5(终端设备未检测到,但是终端设备接收到DCI 6,可以判断出漏检了DCI 5)中包括的第一DAI的取值也为1,则终端设备需要向网络设备上报两个第一信息。
在该示例中,可选地,还假设第一DAI需要满足的第一取值条件为第一DAI的取值满足mod(4*j+Z,X)=Y,其中,假设X取值为6,Y取值为1。由于j是至少一个DAI中包括的第一DAI的取值达到最大值的次数,基于上述示例,j的取值为1。Z为第一DAI的取值,在第一DAI为1的情况下,mod(4*j+Z,X)=Y(mod(4*1+1,6)=1)这一等式成立,那么,终端设备针对C-DAI=1的DCI需要向网络设备报告第一信息;在第一DAI为2、3、4的情况下,mod(4*j+Z,X)=Y这一等式均不成立,那么,终端设备针对C-DAI=2、3、4的DCI不需要向网络设备报告第一信息。其中,DCI 1(终端设备接收到)中包括的第一DAI的取值为1,DCI 5(终端设备未检测到,但是终端设备接收到DCI 6,可以判断出漏检了DCI 5)中包括的第一DAI的取值也为1,则终端设备需要向网络设备上报两个第一信息。
基于此,假设终端设备按照HARQ-ACK信息和第一信息分别生成子码本并组合的方式形成第一码本,且假设每个第一信息占用的比特数S为3,则终端设备基于第一信息生成的第二子码本的比特数为T*S为6,终端设备可以将第二子码本附在第一子码本之后,或者,将第一子码本附在第二子码本之后,形成12个比特的第一码本。
基于此,假设终端设备按照在基于HARQ-ACK信息生成的第一子码本中添加第一信息的方式形成第一码本,且假设每个第一信息占用的比特数S为3,则终端设备在第一子码本的第一个比特b 1之后添加DCI1中的第一DAI对应的3比特第一信息,在第一子码本的第五个比特b 5之后添加DCI 5中的第一DAI对应的3比特第一信息,从而形成12个比特的第一码本。
综上所述,本申请实施例提供的技术方案,通过为终端设备报告基于PDSCH确定的第一信息设置了第一报告条件,在满足第一报告条件的情况下,终端设备才会向网络设备报告第一信息,从而,在下行数据调度密集、上行反馈相对较少等场景下,终端设备无需针对每个PDSCH均报告第一信息,节省了上行开销,有助于降低终端设备的功耗和处理资源。并且,在本申请实施例中,终端设备可以将第一信息与其它上行信息(如HARQ-ACK信息等)组合在一起报告至网络设备,减少了终端设备与网络设备之间往来的信息数量,有助于提升系统的传输效率。
在一种可能的实施方式中,第一报告条件包括:DCI包含的第一DAI满足第一取值条件。
终端设备配置HARQ-ACK码本类型为Type-2 HARQ-ACK码本的情况下,网络设备需要向终端设备发送DCI,进而终端设备根据接收到的DCI确定实际调度的PDSCH或SPS PDSCH所需要的HARQ-ACK反馈比特数。本实施方式中,终端设备在本次报告第一信息与上次报告第一信息之间,可以接收来自于网络设备的至少一个DCI,每个DCI中包括至少一个DAI,该至少一个DAI中包括第一DAI。可选地,第一DAI包括至少一个DAI中的Counter DAI。在本实施方式中,第一报告条件包括DCI包含的第一DAI满足第一取值条件,也即,针对来自于网络设备的至少一个DCI中的任意一个DCI,若该DCI包含的第一DAI满足第一取值条件,则终端设备针对该DCI向网络设备报告第一信息;若该DCI包含的第一DAI不满足第一取值条件,则终端设备不针对该DCI向网络设备报告第一信息。
其中,第一取值条件可以是通信协议定义的,也可以是网络设备配置的,例如,网络设备通过高层信令配置第一取值条件,可选地,高层信令包括以下至少一项:SIB、RRC、MAC。本申请实施例对第一取值条件的具体内容不作限定。在一个示例中,第一取值条件包括第一DAI的取值为第一数值;其中,第一数值由通信协议定义;或者,第一数值由网络设备配置,例如,网络设备通过高层信令配置第一数值,可选地,高层信令包括以下至少一项:SIB、RRC、MAC。在另一个示例中,第一取值条件包括第一DAI的取值满足如下条件:mod(4*j+Z,X)=Y,其中,mod(4*j+Z,X)用于求取(4*j+Z)除以X的余数;j为来自于网络设备的至少一个DCI中包含的第一DAI的取值达到最大值的次数;Z为第一DAI的 取值;X为第一数量阈值,该第一数量阈值由通信协议定义,或者,该第一数量阈值由网络设备配置,例如,网络设备通过高层信令配置第一数量阈值,可选地,高层信令包括以下至少一项:SIB、RRC、MAC;Y为第一参考值,该第一参考值由通信协议定义,或者,该第一参考值由网络设备配置,例如,网络设备通过高层信令配置第一参考值,可选地,高层信令包括以下至少一项:SIB、RRC、MAC。
本实施方式中,虽然网络设备向终端设备发送了至少一个DCI,但终端设备却并不一定全部检测到,而由于每个DCI中均包括第一DAI,通过各个DCI中的第一DAI,终端设备可以判断是否漏检DCI。若通过某一DCI包含的第一DAI,终端设备确定漏检了该DCI之前的DCI,而之前的DCI包含的第一DAI满足第一取值条件的情况下,终端设备还是会针对之前的DCI向网络设备报告第一信息。因此,本申请实施例中,包含满足第一取值条件的第一DAI的DCI可以被终端设备接收到,也可以未被终端设备检测到。
由于第一信息是基于PDSCH确定的,在DCI包含的第一DAI满足第一取值条件的情况下,终端设备向网络设备报告第一信息,并且,第一信息对应的PDSCH为该DCI调度的PDSCH。然而,由于终端设备并不一定检测到包含满足第一取值条件的第一DAI的DCI,进而,在终端设备漏检的情况下,终端设备无法确定该DCI调度的PDSCH,因此,第一信息的内容需要相应做出改变。本实施方式中,在DCI包含的第一DAI满足第一取值条件,且终端设备接收到该DCI的情况下,第一信息对应的PDSCH为该DCI调度的PDSCH;在DCI包含的第一DAI满足第一取值条件,且终端设备未检测到该DCI的情况下,第一信息为第一指示值;其中,第一指示值由通信协议定义;或者,第一指示值由网络设备配置,例如,网络设备通过高层信令配置第一指示值,可选地,高层信令包括以下至少一项:SIB、RRC、MAC。
示例性地,如图4所示,网络设备向终端设备发送了4个DCI,这4个DCI调度的PDSCH分别为PDSCH 1、PDSCH 2、PDSCH 3、PDSCH 4,且这4个DCI包含的第一DAI(C-DAI)分别为C-DAI=1、C-DAI=2、C-DAI=3、C-DAI=4。如图4所示,终端设备未检测到调度PDSCH 2的DCI(该DCI包含的第一DAI为2)。
假设第一取值条件为第一DAI为4,则终端设备接收到调度PDSCH 4的DCI(该DCI包含的第一DAI为4)时,终端设备向网络设备报告第一信息,且该第一信息对应的PDSCH为PDSCH 4。
假设第一取值条件为第一DAI为3,则终端设备接收到调度PDSCH 3的DCI(该DCI包含的第一DAI为3)时,终端设备向网络设备报告第一信息,且该第一信息对应的PDSCH为PDSCH 3。
假设第一取值条件为第一DAI为1,则终端设备接收到调度PDSCH 1的DCI(该DCI包含的第一DAI为1)时,终端设备向网络设备报告第一信息,且该第一信息对应的PDSCH为PDSCH 1。
假设第一取值条件为第一DAI为2,而终端设备未检测到调度PDSCH 2的DCI(该DCI包含的第一DAI为2),但终端设备接收到调度PDSCH 3的DCI(该DCI包含的第一DAI为3),因此,终端设备可以确定其漏检了调度PDSCH 2的DCI(该DCI包含的第一DAI为2),则终端设备向网络设备反馈第一信息,该第一信息为第一指示值。
综上所述,本申请实施例提供的技术方案,通过终端设备配置Type-2 HARQ-ACK码本的情况下,基于DCI包含的第一DAI是否满足一定的取值条件,来确定是否向网络设备报告第一信息,实现了利用网络设备调度PDSCH或者SPS PDSCH的DCI来设置第一报告条件,而无需引入新的消息或信令,兼容了通信系统原有的信令设计。并且,本申请实施例中,在终端设备无法确定第一信息对应的PDSCH的情况下,设置第一信息为指示值,以避免由于终端设备漏检DCI导致的终端设备和网络设备对第一信息负载大小理解的不一致,而避免网络设备无法检测到第一信息。
在另一种可能的实施方式中,第一报告条件包括:第一时隙计时集合中存在满足第二取值条件的第一时隙计时。
终端设备配置HARQ-ACK码本类型为Type-1 HARQ-ACK码本的情况下,终端设备可以获取第一时隙计时集合(a set of slot timing values K1,K1 set),进而基于第一时隙计时集合确定候选PDSCH接收机会,并为半静态确定的每个候选PDSCH接收机会预留HARQ-ACK反馈比特。其中,第一时隙计时集合既可以是通信协议定义的,也可以是网络设备通过RRC信令发送至终端设备的。本实施方式中,利用第一时隙计时集合设置第一报告条件。终端设备可以遍历第一时隙计时集合中的每一个第一时隙,并且,在第一时隙计时集合中存在满足第二取值条件的第一时隙计时的情况下,向网络设备报告第一信息。
其中,第二取值条件可以是通信协议定义的,也可以是网络设备配置的,例如,网络设备通过高层信令配置第二取值条件,可选地,高层信令包括以下至少一项:SIB、RRC、MAC。本申请实施例对第二取值条件的具体内容不作限定。在一个示例中,第二取值条件包括第一时隙计时等于第二数值;其中,第二数值由通信协议定义;或者,第二数值由网络设备配置,例如,网络设备通过高层信令配置第二数值,可选地,高层信令包括以下至少一项:SIB、RRC、MAC。在另一个示例中,第二取值条件包括第一时隙计时满足如下条件:mod(K1,N)=M,其中,mod(K1,N)用于求取K1除以N的余数;K1为第一时 隙计时;M为第二参考值,该第二参考值由通信协议定义,或者,该第二参考值由网络设备配置,例如,网络设备通过高层信令配置第二参考值,可选地,高层信令包括以下至少一项:SIB、RRC、MAC;N为第三参考值,该第三参考值由通信协议定义,或者,该第三参考值由网络设备配置,例如,网络设备通过高层信令配置第三参考值,可选地,高层信令包括以下至少一项:SIB、RRC、MAC。
由于第一信息是基于PDSCH确定的,终端设备需要先确定第一信息对应的PDSCH,再基于PDSCH确定第一信息。本实施方式对第一信息对应的PDSCH的确定方式不作限定,可选地,第一信息对应的PDSCH为DCI调度的PDSCH。下面,介绍说明几种示例性地确定第一信息对应的PDSCH的方式。
在一个示例中,第一信息对应的PDSCH为满足第二取值条件的第一时隙计时对应的时间单元内最近的PDSCH,其中,该PDSCH为DCI调度的PDSCH或者SPS PDSCH。应理解,最近的PDSCH包括最近接收到的PDSCH,或者最近调度的PDSCH,或者最近检测的PDSCH。在该示例中,满足第二取值条件的第一时隙计时对应的时间单元内,存在DCI调度的PDSCH或者SPS PDSCH。然而,实际应用中,满足第二取值条件的第一时隙计时对应的时间单元内却并非一定存在DCI调度的PDSCH或者SPS PDSCH,因此,第一信息的内容需要相应做出改变。基于此,可选地,在满足第二取值条件的第一时隙计时对应的时间单元内,不存在DCI调度的PDSCH或者SPS PDSCH的情况下,第一信息为第一指示值,该第一指示值由通信协议定义,或者,该第一指示值由网络设备配置,例如,网络设备通过高层信令配置第一指示值,可选地,高层信令包括以下至少一项:SIB、RRC、MAC。其中,第一时隙计时对应的时间单元包括以下任意一项:帧、子帧、时隙、子时隙、OFDM(Orthogonal Frequency Division Multiplexing,正交频分复用)符号。
示例性地,如图5所示,第一时隙计时集合K1 set包括两个第一时隙计时,分别为K1=1和K1=2,其中,K1=1对应的时间单元为下行时隙#2,K1=2对应的时间单元为下行时隙#1。假设第二取值条件为第一时隙计时等于1,且假设第一信息对应的PDSCH为等于1的第一时隙计时对应的时间单元内最近的PDSCH。由于本示例中,第一时隙计时集合中存在等于1的第一时隙计时(K1=1),则终端设备向网络设备报告第一信息,且如图5所示,由于等于1的第一时隙计时(K1=1)对应的时间单元(下行时隙#2)内存在DCI调度的PDSCH或者SPS PDSCH,则第一信息对应的PDSCH为下行时隙#2中最右侧的PDSCH。假设等于1的第一时隙计时(K1=1)对应的时间单元(下行时隙#2)内不存在DCI调度的PDSCH或者SPS PDSCH,则终端设备向网络设备报告的第一信息为第一指示值。假设第二取值条件为第一时隙计时满足mod(K1,N)=M,其中,假设N取值为2,M取值为1,且假设第一信息对应的PDSCH为满足第二取值条件的第一时隙计时对应的时间单元内最近的PDSCH。由于本示例中,第一时隙计时集合中存在第一时隙计时(K1=1)满足第二取值条件(mod(1,2)=1这一等式成立),则终端设备向网络设备报告第一信息。且如图5所示,由于满足第二取值条件的第一时隙计时(K1=1)对应的时间单元(下行时隙#2)内存在DCI调度的PDSCH或者SPS PDSCH,则第一信息对应的PDSCH为下行时隙#2中最右侧的PDSCH。假设满足第二取值条件的第一时隙计时(K1=1)对应的时间单元(下行时隙#2)内不存在DCI调度的PDSCH或者SPS PDSCH,则终端设备向网络设备报告的第一信息为第一指示值。
在另一个示例中,在满足第二取值条件的第一时隙计时对应的时间单元内,终端设备接收到包含第一指示域的DCI的情况下,第一信息对应的PDSCH为包含第一指示域的DCI调度的PDSCH;第一指示域用于指示终端设备报告第一信息。可选地,在满足第二取值条件的第一时隙计时对应的时间单元内,终端设备接收到u个包含第一指示域的DCI,u为正整数;第一信息对应的PDSCH为u个DCI中最近的DCI调度的PDSCH;或者,第一信息对应的PDSCH为u个DCI调度的PDSCH中最近的PDSCH。应理解,最近的PDSCH包括最近接收到的PDSCH,或者最近调度的PDSCH,或者最近检测的PDSCH。可选地,在满足第二取值条件的第一时隙计时对应的时间单元内,终端设备未接收到包含第一指示域的DCI的情况下,第一信息为第一指示值;第一指示域用于指示终端设备报告第一信息;第一指示值由通信协议定义,或者,第一指示值由网络设备配置,例如,网络设备通过高层信令配置第一指示值,可选地,高层信令包括以下至少一项:SIB、RRC、MAC。其中,第一时隙计时对应的时间单元包括以下任意一项:帧、子帧、时隙、子时隙、OFDM符号。
示例性地,如图5所示,第一时隙计时集合K1 set包括两个第一时隙计时,分别为K1=1和K1=2,其中,K1=1对应的时间单元为下行时隙#2,K1=2对应的时间单元为下行时隙#1。假设第二取值条件为第一时隙计时等于1,且假设第一信息对应的PDSCH为包含第一指示域的DCI调度的PDSCH。由于本示例中,第一时隙计时集合中存在等于1的第一时隙计时(K1=1),则终端设备向网络设备报告第一信息。并且,如图5所示,假设网络设备调度下行时隙#2内左侧的PDSCH时,在DCI中携带了第一指示域用于指示终端设备反馈第一信息,则终端设备在等于1的第一时隙计时(K1=1)对应的时间单元(下行时隙#2)内接收到包含第一指示域的DCI,进而第一信息对应的PDSCH为该DCI调度的PDSCH,即下行时隙#2内左侧的PDSCH。此外,如图5所示,假设网络设备调度下行时隙#2内PDSCH时,在DCI中均携带 了第一指示域用于指示终端设备反馈第一信息,则终端设备在等于1的第一时隙计时(K1=1)对应的时间单元(下行时隙#2)内接收到两个包含第一指示域的DCI,进而第一信息对应的PDSCH为这两个DCI调度的PDSCH中最近的PDSCH,即下行时隙#2内右侧的PDSCH。
综上所述,本申请实施例提供的技术方案,通过终端设备配置Type-1 HARQ-ACK码本的情况下,基于第一时隙计时集合中的第一时隙计时是否满足一定的取值条件,来确定是否向网络设备报告第一信息,实现了利用第一时隙计时集合来设置第一报告条件,而无需引入新的消息或信令,兼容了通信系统原有的信令设计。并且,本申请实施例中,在终端设备无法确定第一信息对应的PDSCH的情况下,设置第一信息为指示值,以避免由于终端设备漏检DCI导致的终端设备和网络设备对第一信息负载大小理解的不一致,而避免网络设备无法检测到第一信息。
在再一种可能的实施方式中,第一报告条件包括:终端设备所在的时间单元满足第一时间条件。
本实施方式中,终端设备在其所在的时间单元满足第一时间条件的情况下,向网络设备报告第一信息。可选地,终端设备在其所在的时间单元满足第一时间条件的情况下,在其所在的时间单元向网络设备报告第一信息。可选地,终端设备所在的时间单元包括终端设备当前所在的时间单元。其中,第一时间条件可以是通信协议定义的,也可以是网络设备配置的,例如,网络设备通过高层信令配置第一时间条件,可选地,高层信令包括以下至少一项:SIB、RRC、MAC。本申请实施例对第一时间条件的具体内容不作限定。在一个示例中,第一时间条件包括:终端设备所在的时间单元为终端设备所在的上下行传输周期的最后一个时间单元;或者,第一时间条件包括:终端设备所在的时间单元为终端设备所在的上下行传输周期的第i个时间单元,i为正整数,i由通信协议定义,或者,i由网络设备配置。
其中,终端设备可以通过来自于网络设备的RRC信令获取上下行传输周期。可选地,该上下行传输周期包括一个传输时长,例如,该上下行传输周期包括P(P为正数);或者,该上下行传输周期包括至少两个不同的传输时长,例如,该上下行传输周期包括P和P2(P2为正数,且P2不等于P)。
在上下行传输周期包括至少两个不同的传输时长时,终端设备所在的上下行传输周期的最后一个时间单元,可以是终端设备所在的上下行传输周期包括的所有传输时长的最后一个时间单元,也即,终端设备在上下行传输周期包括的最后一个传输时长的最后一个时间单元,向网络设备报告第一信息;或者,终端设备所在的上下行传输周期的最后一个时间单元,可以是终端设备所在的上下行传输周期包括的各个传输时长的最后一个时间单元,也即,终端设备可以在上下行传输周期包括的各个传输时长的最后一个时间单元,均向网络设备报告第一信息。
在上下行传输周期包括至少两个不同的传输时长时,终端设备所在的上下行传输周期的第i个时间单元,可以是终端设备所在的上下行传输周期包括的所有传输时长的第i个时间单元,也即,终端设备在上下行传输周期包括的最后一个传输时长的第i个时间单元,向网络设备报告第一信息;或者,终端设备所在的上下行传输周期的第i个时间单元,可以是终端设备所在的上下行传输周期包括的各个传输时长的第i个时间单元,也即,终端设备可以在上下行传输周期包括的各个传输时长的第i个时间单元,均向网络设备报告第一信息。
由于第一信息是基于PDSCH确定的,终端设备需要先确定第一信息对应的PDSCH,再基于PDSCH确定第一信息。本实施方式对第一信息对应的PDSCH的确定方式不作限定,可选地,第一信息对应的PDSCH为DCI调度的PDSCH。下面,介绍说明几种示例性地确定第一信息对应的PDSCH的方式。
在一个示例中,第一信息对应的PDSCH为终端设备所在的上下行传输周期内最近的PDSCH;其中,该PDSCH为DCI调度的PDSCH或者SPS PDSCH。应理解,最近的PDSCH包括最近接收到的PDSCH,或者最近调度的PDSCH,或者最近检测的PDSCH。在该示例中,终端设备所在的上下行传输周期内,存在DCI调度的PDSCH或者SPS PDSCH。然而,实际应用中,终端设备所在的上下行传输周期内并非一定存在DCI调度的PDSCH或者SPS PDSCH,因此,第一信息的内容需要相应做出改变。基于此,可选地,在终端设备所在的上下行传输周期内,不存在DCI调度的PDSCH或者SPS PDSCH的情况下,第一信息为第一指示值,第一指示值由通信协议定义,或者,第一指示值由网络设备配置,例如,网络设备通过高层信令配置第一指示值,可选地,高层信令包括以下至少一项:SIB、RRC、MAC。
在另一个示例中,在终端设备所在的上下行传输周期内,终端设备接收到包含第一指示域的DCI的情况下,第一信息对应的PDSCH为包含第一指示域的DCI调度的PDSCH;第一指示域用于指示终端设备报告第一信息。可选地,在终端设备所在的上下行传输周期内,终端设备接收到w个包含第一指示域的DCI,w为正整数;第一信息对应的PDSCH为w个DCI中最近的DCI调度的PDSCH;或者,第一信息对应的PDSCH为w个DCI调度的PDSCH中最近的PDSCH。应理解,最近的PDSCH包括最近接收到的PDSCH,或者最近调度的PDSCH,或者最近检测的PDSCH。可选地,在终端设备所在的上下行传输周期内,终端设备未接收到包含第一指示域的DCI的情况下,第一信息为第一指示值;第一指示域用于指示终 端设备报告第一信息;第一指示值由通信协议定义,或者,第一指示值由网络设备配置,例如,网络设备通过高层信令配置第一指示值,可选地,高层信令包括以下至少一项:SIB、RRC、MAC。
综上所述,本申请实施例提供的技术方案,通过基于终端设备所在的时间单元是否满足一定的取值条件,来确定是否向网络设备报告第一信息,实现了利用终端设备所在的时间单元来设置第一报告条件,而无需引入新的消息或信令,兼容了通信系统原有的信令设计。并且,本申请实施例中,在终端设备无法确定第一信息对应的PDSCH的情况下,设置第一信息为指示值,以避免由于终端设备漏检DCI导致的终端设备和网络设备对第一信息负载大小理解的不一致,而避免网络设备无法检测到第一信息。
在又一种可能的实施方式中,第一报告条件包括:终端设备传输HARQ-ACK码本。
本实施方式中,终端设备在传输HARQ-ACK码本时,向网络设备报告第一信息。可选地,终端设备配置HARQ-ACK码本类型为Type-1 HARQ-ACK码本,或者,终端设备配置HARQ-ACK码本类型为Type-2 HARQ-ACK码本。可选地,终端设备传输的HARQ-ACK码本和报告的第一信息,可以承载在相同的消息中发送至网络设备;也可以承载在不同的消息中同时或者不同时地发送至网络设备,本实施方式对HARQ-ACK码本和第一信息的发送方式不作限定。
由于第一信息是基于PDSCH确定的,终端设备需要先确定第一信息对应的PDSCH,再基于PDSCH确定第一信息。本实施方式对第一信息对应的PDSCH的确定方式不作限定,可选地,第一信息对应的PDSCH为DCI调度的PDSCH。下面,介绍说明几种示例性地确定第一信息对应的PDSCH的方式。
在一个示例中,第一信息对应的PDSCH为HARQ-ACK码本中的HARQ-ACK信息对应的最近的PDSCH;PDSCH为DCI调度的PDSCH或者SPS PDSCH。然而,由于终端设备并非一定接收到来自于网络设备的DCI,因而HARQ-ACK码本中的HARQ-ACK信息也并非一定存在对应的PDSCH,在这种情况下,第一信息的内容需要相应做出改变。本实施方式中,在HARQ-ACK码本中存在对应有PDSCH的HARQ-ACK信息的情况下,第一信息对应的PDSCH为HARQ-ACK码本中的HARQ-ACK信息对应的最近的PDSCH;在HARQ-ACK码本中的全部HARQ-ACK信息均没有对应的PDSCH的情况下,第一信息为第一指示值;PDSCH为DCI调度的PDSCH或者SPS PDSCH;第一指示值由通信协议定义,或者,第一指示值由网络设备配置,例如,网络设备通过高层信令配置第一指示值,可选地,高层信令包括以下至少一项:SIB、RRC、MAC。应理解,最近的PDSCH包括最近接收到的PDSCH,或者最近调度的PDSCH,或者最近检测的PDSCH。
示例性地,如图6所示,终端设备在时隙#8通过PUCCH传输HARQ-ACK码本,则终端设备向网络设备报告第一信息。如图6所示,该HARQ-ACK码本中的HARQ-ACK信息对应的PDSCH为PDSCH 1至PDSCH 5,其中,PDSCH 5是HARQ-ACK码本中的HARQ-ACK信息对应的最近的PDSCH,则第一信息对应的PDSCH为PDSCH 5。
示例性地,如图7所示,终端设备在时隙#8通过PUCCH传输HARQ-ACK码本,则终端设备向网络设备报告第一信息。如图7所示,该HARQ-ACK码本中的HARQ-ACK信息对应的PDSCH为PDSCH 1至PDSCH 5,以及SPS PDSCH 6,其中,SPS PDSCH 6是HARQ-ACK码本中的HARQ-ACK信息对应的最近的PDSCH,则终端设备向网络设备报告的第一信息对应的PDSCH为SPS PDSCH 6。
示例性地,终端设备在时隙#8通过PUCCH传输HARQ-ACK码本,则终端设备向网络设备报告第一信息。假设该HARQ-ACK码本中包括7比特的HARQ-ACK信息,这7比特的HARQ-ACK信息分别对应于时隙#1至时隙#7内的PDSCH接收情况。假设时隙#1至时隙#7均没有PDSCH传输,即HARQ-ACK码本中的全部HARQ-ACK信息均没有对应的PDSCH,则终端设备向网络设备报告的第一信息为第一指示值。在另一个示例中,在终端设备接收到包含第一指示域的DCI,且DCI中的时序指示信息所指示的时间单元为HARQ-ACK码本所在的时间单元的情况下,第一信息对应的PDSCH为DCI调度的PDSCH;第一指示域用于指示终端设备报告第一信息。其中,HARQ-ACK码本所在的时间单元包括终端设备传输HARQ-ACK码本的时间单元。可选地,终端设备接收到v个包含第一指示域的DCI,且v个DCI中的时序指示信息所指示的时间单元均为HARQ-ACK码本所在的时间单元,v为正整数;第一信息对应的PDSCH为v个DCI中最近的DCI调度的PDSCH;或者,第一信息对应的PDSCH为v个DCI调度的PDSCH中最近的PDSCH。应理解,最近的PDSCH包括最近接收到的PDSCH,或者最近调度的PDSCH,或者最近检测的PDSCH。可选地,在终端设备未接收到包含第一指示域的DCI的情况下,或者,在终端设备接收到包含第一指示域的DCI,但DCI中的时序指示信息所指示的时间单元不为HARQ-ACK码本所在的时间单元的情况下,第一信息为第一指示值;第一指示域用于指示终端设备报告第一信息;第一指示值由通信协议定义,或者由网络设备配置,例如,网络设备通过高层信令配置第一指示值,可选地,高层信令包括以下至少一项:SIB、RRC、MAC。
综上所述,本申请实施例提供的技术方案,通过基于终端设备是否传输HARQ-ACK码本,来确定是 否向网络设备报告第一信息,实现了利用HARQ-ACK码本的传输来设置第一报告条件,而无需引入新的消息或信令,兼容了通信系统原有的信令设计。并且,本申请实施例中,在终端设备无法确定第一信息对应的PDSCH的情况下,设置第一信息为指示值,以避免由于终端设备漏检DCI导致的终端设备和网络设备对第一信息负载大小理解的不一致,而避免网络设备无法检测到第一信息。
