Description

信息反馈方法、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,特别涉及一种信息反馈方法、装置、设备及存储介质。
背景技术
CSI(Channel State Information,信道状态信息)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。
目前,在NR(New Radio,新空口)系统的相关技术中,CSI是基于终端设备对CSI-RS(CSI Reference Signals,CSI参考信号)资源的测量获取并上报至网络设备的,具体而言,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。在一些实现中,为了同时满足URLLC(Ultra-Reliable and Low Latency Communication,低时延高可靠通信)业务的低时延与高可靠这两个特性,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。
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,提出了一种新型的信道状态信息。而关于如何得到该新型的信道状态信息,还需要进一步地讨论和研究。

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、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。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 PCTCN2021109388-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。
2、物理层优先级。
在NR系统中,为了更好的支持URLLC业务,对于上行信道在物理层引入了高优先级、低优先级。其中,priority index 0(优先级索引为0)表示低优先级,priority index 1(优先级索引为1)表示高优先级。终端设备可以根据网络设备的配置信息和/或指示信息,确定上行信道(上行信道包括:PUSCH、PUCCH)的优先级索引。
3、HARQ(Hybrid Automatic Repeat Request,混合自动重传请求)-ACK(Acknowledgement,肯定确认)码本。
NR系统支持两种HARQ-ACK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)、K1set(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。
4、MCS(Modulation and Coding Scheme,调制与编码策略)table(表格)。
NR系统的上行和下行均支持3个MCS表格,分别为256QAM(Quadrature Amplitude Modulation,正交振幅调制)、64QAM和lowSE64QAM。
在NR系统设计之初,只支持256QAM和64QAM两个MCS表格,其target(目标)BLER(Block Error Rate,误块率)为1e-1,旨在支持eMBB(Enhanced Mobile Broadband,增强移动宽带)业务,后来,为了更好的支持URLLC业务,设计了lowSE64QAM MCS表格,其目标BLER为1e-5。
示例性地,如下述表一所示,其示出了一个64QAM的MCS表格(MCS索引配置信息)。在MCS索引为0至28时,MCS索引所指示的调制阶数(Modulation Order)、码率(Target Code Rate)、频谱效率(Spectral Efficiency),可以用于初传调度和重传调度;在MCS索引为29至31时,MCS索引所指示的调制阶数、码率、频谱效率所对应的指示内容为“reserved(保留)”,可以用于重传调度。

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/n-5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,提出了基于PDSCH的解调和/或测量的信道状态信息,或称为“reporting of delta MCS(MCS差值的报告)”。其中,delta MCS为目标MCS和参考MCS之间的差值,目标MCS为使得使用该MCS接收的TB(Transport Block,传输块)的预测BLER(estimated BLER)小于或等于目标BLER的最大MCS。由于信道状态信息是基于PDSCH的解调和/或测量得到的,不需要额外的测量资源与测量时间,因此,基于PDSCH的解调和/或测量的信道状态信息的上报可以降低终端设备得到信道状态信息的计算时延与功耗,同时可以节约CSI-RS资源,使得系统有更多的资源来传输下行数据,提升网络容量。
然而,如果针对每个PDSCH均计算并上报信道状态信息,上报开销将会大大增大。如何平衡上报开销与信道状态信息上报的准确性,尚未提及和讨论。基于此,本申请实施例提 供了一种信息反馈方法,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。
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反馈方法的流程图,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,终端设备向网络设备发送第一反馈信息,第一反馈信息是基于参考MCS得到的;其中,参考MCS与第一PDSCH对应,或者,参考MCS由网络设备配置,或者,参考MCS由通信协议预定义。
第一反馈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,第一反馈信息与至少一个PDSCH对应,换句话说,第一反馈信息反映了至少一个PDSCH的信道质量和/或信道特性。
应理解,“第一反馈信息”这一名称可能会发生变化,例如,“第一反馈信息”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“reporting of delta MCS(MCS差值的报告)”,或者称为“case-2reporting(情况2报告)”。为了便于描述,本申请实施例将与至少一个PDSCH对应的、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“第一反馈信息”。
本申请实施例对第一反馈信息的内容不作限定,可选地,第一反馈信息包括基于至少一个PDSCH的解调和/或测量得到的信道状态信息;或者,第一反馈信息包括第一差值,第一差值为目标MCS与参考MCS之间的差值。其中,目标MCS是基于至少一个PDSCH确定的MCS;参考MCS是至少一个PDSCH中第一PDSCH对应的MCS,或者,参考MCS是网络设备配置的MCS,或者,参考MCS是通信协议预定义的MCS。可选地,第一PDSCH对应 的MCS为调度该第一PDSCH的DCI中包括的MCS。
在一个示例中,至少一个PDSCH的数量为k,k等于1或者k为大于1的整数,终端设备基于k个PDSCH,确定目标MCS。可选地,目标MCS是基于k个中间目标MCS得到的,k个中间目标MCS中第i个中间目标MCS是基于k个PDSCH中第i个PDSCH得到的,i为小于或等于k的正整数。换句话说,终端设备基于k个PDSCH确定了k个中间目标MCS,再基于k个中间目标MCS确定了目标MCS。其中,中间目标MCS是为使得使用该MCS接收的TB的预测BLER小于或等于目标BLER的最大MCS。可选地,终端设备基于相同的目标BLER确定k个中间目标MCS。应理解,在k等于1的情况下,终端设备基于一个PDSCH确定目标MCS,此时,目标MCS即为这一个PDSCH的中间目标MCS。
本申请实施例对终端设备基于k个中间目标MCS确定目标MCS的方式不作限定,在一个示例中,目标MCS为以下任意一项:k个中间目标MCS的最小值、k个中间目标MCS的平均值、k个中间目标MCS的最大值。可选地,在k个中间目标MCS的平均值为非整数的情况下,终端设备对k个中间目标MCS的平均值进行取整处理后得到目标MCS,该取整处理包括但不限于:四舍五入、向上取整、向下取整。
由上述介绍说明可知,在一些实现中,参考MCS是至少一个PDSCH中的第一PDSCH对应的MCS。基于此,终端设备需要从至少一个PDSCH中明确第一PDSCH,再基于第一PDSCH相关的信息确定参考MCS。在一个示例中,第一PDSCH包括以下任意一项:至少一个PDSCH中最近的PDSCH、至少一个PDSCH中最近的初传PDSCH、至少一个PDSCH中最近的PDSCH对应的初传PDSCH、至少一个PDSCH中对应的MCS最小的PDSCH、至少一个PDSCH中对应的MCS最大的PDSCH。可选地,至少一个PDSCH中对应的MCS最小的PDSCH,和/或,至少一个PDSCH中对应的MCS最大的PDSCH,不包括对应的MCS所对应的指示内容为保留的PDSCH。
示例性地,至少一个PDSCH为PDSCH 1、PDSCH 2、PDSCH 3和PDSCH 4,它们对应的MCS分别为3、4、5、4;其中,PDSCH 1、PDSCH 2和PDSCH 3均为初传,PDSCH 4为重传,且PDSCH 4对应的初传PDSCH为PDSCH 0。那么,若第一PDSCH包括至少一个PDSCH中最近的PDSCH,则第一PDSCH为PDSCH 4;若第一PDSCH为至少一个PDSCH中最近的初传PDSCH,则第一PDSCH为PDSCH 3;若第一PDSCH为至少一个PDSCH中最近的PDSCH对应的初传PDSCH,则第一PDSCH为PDSCH 0;若第一PDSCH为至少一个PDSCH中对应的MCS最小的PDSCH,则第一PDSCH为PDSCH 1;若第一PDSCH为至少一个PDSCH中对应的MCS最大的PDSCH,则第一PDSCH为PDSCH 2。
示例性地,至少一个PDSCH为PDSCH 1、PDSCH 2、PDSCH 3和PDSCH 4,终端设备基于PDSCH 1至PDSCH 4确定第一反馈信息。在终端设备基于PDSCH 1至PDSCH 4确定目标MCS时,终端设备基于相同的目标BLER(如1e-5的BLER)确定PDSCH 1至PDSCH 4分别对应的中间目标MCS,得到PDSCH 1至PDSCH 4对应的中间目标MCS分别为4、5、4、3。若目标MCS为PDSCH 1至PDSCH 4对应的中间目标MCS的最小值,则目标MCS为3;若目标MCS为PDSCH 1至PDSCH 4对应的中间目标MCS的平均值,则目标MCS为4。假设PDSCH 1至PDSCH 4分别对应的MCS为3、4、5、4,且参考MCS为PDSCH 1至PDSCH 4中某一个PDSCH对应的MCS,若参考MCS为PDSCH 1至PDSCH 4中对应的MCS最大的PDSCH所对应的MCS,则参考MCS为5(PDSCH 3对应的MCS);若参考MCS为PDSCH 1至PDSCH 4中最近的PDSCH对应的MCS,则参考MCS为4(PDSCH 4对应的MCS)。进一步地,终端设备基于目标MCS与参考MCS的差值,确定第一反馈信息。例如,第一反馈信息包括delta MCS,若目标MCS为3,参考MCS为5,则delta MCS=3-5=-2;若目标MCS为4,参考MCS为4,则delta MCS=4-4=0。
本申请实施例中,第一反馈信息的确定,还需要基于一个假设的TB大小确定。基于此,在一个示例中,第一反馈信息是基于第一TB得到的。由于第一反馈信息与至少一个PDSCH 对应,从而可选地,第一TB的大小是基于至少一个PDSCH中的第一PDSCH得到的,或者,第一TB的大小是基于至少一个PDSCH得到的。示例性地,在第一TB的大小是基于第一PDSCH得到的情况下,第一TB的大小是基于以下至少一项与第一PDSCH相关的信息得到的:目标MCS、第一PDSCH占用的物理资源块PRB,该目标MCS为基于第一PDSCH得到的;在第一TB的大小是基于至少一个PDSCH得到的情况下,第一TB的大小是基于以下至少一项与至少一个PDSCH相关的信息得到的:目标MCS、至少一个PDSCH占用的PRB,该目标MCS为基于至少一个PDSCH得到的。有关第一PDSCH的确定方式、目标MCS的计算方式等介绍说明,请参见上述实施例的介绍说明,此处不多赘述。
终端设备在得到第一反馈信息之后,可以向网络设备发送第一反馈信息,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资源向网络设备发送第一反馈信息。本申请实施例对第一反馈信息的上报方式不作限定。在一个示例中,终端设备在向网络设备发送第一反馈信息时,将第一反馈信息作为单独的上行信息上报至网络设备,此时,终端设备可以同时上报第一反馈信息与其它上行信息(如HARQ-ACK码本),也可以不同时上报第一反馈信息和其它上行信息(如HARQ-ACK码本)。在另一个示例中,终端设备将第一反馈信息与其它的上行信息(如HARQ-ACK码本)组合在一起上报至网络设备。有关终端设备向网络设备发送第一反馈信息的其它介绍说明,请参见下述实施例,此处不多赘述。
综上所述,本申请实施例提供的技术方案,通过终端设备基于参考MCS确定反馈信息,并向网络设备上报反馈信息,以向网络设备指示通信链路的信道质量和/或信道特性,由于参考MCS是PDSCH对应的MCS,或者是网络设备配置或通信协议预定义的MCS,从而不需要额外的针对通信链路的测量资源与测量时间,有助于降低终端设备得到信道状态相关的信息的计算时延与功耗,同时节约CSI-RS资源,使得通信系统有更多的资源来传输下行数据,提升网络容量。并且,本申请实施例中,终端设备上报的反馈信息对应于至少一个PDSCH,降低了反馈信息的上报开销。
下面,对至少一个PDSCH的确定方式进行介绍说明。
在一个示例中,第一PDSCH包括以下任意一项:第一时刻之前最近的PDSCH、第一时刻之前最近的初传PDSCH、第一时刻之前最近的PDSCH对应的初传PDSCH。
由上述实施例可知,第一PDSCH为至少一个PDSCH中的PDSCH(或者说第一PDSCH包含在至少一个PDSCH中),且第一PDSCH可以包括以下任意一项:至少一个PDSCH中最近的PDSCH、至少一个PDSCH中最近的初传PDSCH、至少一个PDSCH中最近的PDSCH对应的初传PDSCH。结合本示例,第一PDSCH包括以下任意一项:第一时刻之前最近的PDSCH、第一时刻之前最近的初传PDSCH、第一时刻之前最近的PDSCH对应的初传PDSCH,可以得知,至少一个PDSCH均为第一时刻之前的PDSCH。
本申请实施例中,用于承载第一反馈信息的传输资源的第一个时间单元或者最后一个时间单元为第二时刻,第一时刻早于或等于(或者可以说不晚于)第二时刻。可选地,时间单元包括以下任意一项:符号、时隙、子时隙等。也就是说,至少一个PDSCH均为第一反馈信息的开始发送时刻(用于承载第一反馈信息的传输资源的第一个时间单元)之前的PDSCH,或者至少一个PDSCH均为第一反馈信息的结束发送时刻(用于承载第一反馈信息的传输资源的最后一个时间单元)之前的PDSCH。
上述第一时刻早于或等于第二时刻包括第一时刻早于第二时刻或第一时刻等于第二时刻。在第一时刻早于第二时刻的情况下,可选地,第一时刻与第二时刻之间的时长,等于PDSCH的处理时长,或者大于PDSCH的处理时长。试想,若第一时刻与第二时刻之间的时长小于一个PDSCH的处理时长,则在终端设备上报第一反馈信息或者结束上报第一反馈信息的时刻,最近的PDSCH还未处理完成,则第一反馈信息无法反映该PDSCH对应的信道质 量和/或信道特性。因此,第一反馈信息对应的至少一个PDSCH应该是终端设备已经处理完成的PDSCH,以确保准确指示信道质量和/或信道特性,从而,第一时刻与第二时刻之间的时长,大于或等于一个PDSCH的处理时长。
为确保实时指示信道质量和/或信道特性,在一个示例中,至少一个PDSCH包括等于或晚于(或者可以说不早于)第三时刻的PDSCH,也就是说,至少一个PDSCH均为第三时刻之后(也可以包括第三时刻)的PDSCH。其中,第三时刻早于或等于第一时刻。本申请实施例对第三时刻的确定方式不作限定,可选地,第三时刻与第一时刻之间的时长为第一时长,也即,第三时刻为第一时刻之前间隔第一时长的时刻;或者,第三时刻与第二时刻之间的时长为第二时长,也即,第三时刻为第二时刻之前间隔第二时长的时刻。
结合上述有关至少一个PDSCH为第一时刻之前的PDSCH的介绍说明,可见,至少一个PDSCH为第一时间段内的PDSCH,该第一时间段的起始时刻为第三时刻,该第一时间段的结束时刻为第一时刻;或者可以说,至少一个PDSCH为等于或晚于第三时刻且早于或等于第一时刻的PDSCH。基于此,第一PDSCH还包括以下任意一项:等于或晚于第三时刻且早于或等于第一时刻的PDSCH中对应的MCS最小的PDSCH、等于或晚于第三时刻且早于或等于第一时刻的PDSCH中对应的MCS最大的PDSCH。示例性地,如图4所示,若终端设备需要在第二时刻开始上报第一反馈信息,则终端设备确定第一反馈信息对应的至少一个PDSCH为PDSCH 3至PDSCH 5。如图4所示,至少一个PDSCH为第三时刻与第一时刻之间的PDSCH,该第三时刻与第一时刻之间的时长为第一时长,该第三时刻与第二时刻之间的时长为第二时长,该第一时刻与第二时刻之间的时长等于PDSCH的处理时长。如图4所示,由于PDSCH 1和PDSCH 2在第三时刻之前,与第一反馈信息的上报时刻之间的时长过长,对应的信道质量和/或信道特性的反馈已经非实时,所以至少一个PDSCH不包括PDSCH 1和PDSCH 2;由于PDSCH 6位于第一时刻与第二时刻之间,在终端设备上报第一反馈信息时,PDSCH 6还未处理完成,即PDSCH 6对应的信道质量和/或信道特性无法在第一反馈信息中反馈,所以至少一个PDSCH也不包括PDSCH 6。
在一个示例中,第一PDSCH为至少一个PDSCH中的PDSCH(或者说第一PDSCH包含在至少一个PDSCH中);至少一个PDSCH包括以下任意一项:第一HARQ-ACK码本对应的PDSCH;第一HARQ-ACK码本对应的PDSCH中,对应的服务小区索引相同的PDSCH。
终端设备针对接收到的PDSCH,需要向网络设备反馈PDSCH对应的HARQ-ACK信息,以向网络设备指示PDSCH是否被正确接收。基于此,在一个示例中,至少一个PDSCH包括第一HARQ-ACK码本对应的PDSCH。本申请实施例对第一HARQ-ACK码本的类型不作限定,该第一HARQ-ACK码本可以是上述Type-1 HARQ-ACK码本,也可以是上述Type-2 HARQ-ACK码本。本申请实施例中,第一HARQ-ACK码本对应的PDSCH可以对应于一个或者多个服务小区(或称为对应于一个或者多个CC(Component Carrier,载波单元))。基于此,至少一个PDSCH可以是第一HARQ-ACK码本对应的所有PDSCH;也可以是第一HARQ-ACK码本对应的PDSCH中,对应的服务小区索引相同的PDSCH。
由上述示例可知,终端设备可以将至少一个PDSCH对应的第一反馈信息作为单独的上行信息上报至网络设备,也可以将至少一个PDSCH对应的第一反馈信息与其它上行信息组合上报至网络设备。其中,其它上行信息即可包括HARQ-ACK码本。基于此,在一个示例中,上述方法还包括:终端设备在第一上行资源上,向网络设备发送第一反馈信息和第一HARQ-ACK码本;在另一个示例中,终端设备在第一上行资源上,向网络设备发送第一反馈信息,终端设备在第二上行资源上,向网络设备发送第一HARQ-ACK码本。
本申请实施例中,网络设备可以通过高层信令配置终端设备在第一上行资源上发送第一反馈信息,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;或者,网络设备可以通过DCI指示终端设备在第一上行资源上发送第一反馈信息。在网络设备通过DCI指示终端设备在第一上行资源上发送第一反馈信息的情况下, DCI中的第一指示域用于指示终端设备发送或不发送第一反馈信息,该第一指示域可以是DCI中新定义的指示域,也可以是复用DCI中已有的指示域,本申请实施例对此不作限定。可选地,基于DCI中的第一指示域,在第一HARQ-ACK码本对应的PDSCH所对应的DCI中,存在至少一个DCI中的第一指示域指示终端设备发送第一反馈信息的情况下,终端设备在第一上行资源上,向网络设备发送第一反馈信息。
基于上述实施例,若第一反馈信息与第一HARQ-ACK码本组合上报至网络设备,则可以在第一HARQ-ACK码本中预留一定的比特来承载第一反馈信息,可选地,第一HARQ-ACK码本中预留第一反馈比特以用于承载第一反馈信息。本申请实施例对第一反馈比特的比特数不作限定,假设网络设备通过高层信令为终端设备配置了m个服务小区,m为正整数,该高层信令包括以下至少一项:SIB、RRC、MAC;在一个示例中,第一反馈信息的比特数包括:m个第一反馈比特的比特数,m个服务小区中每个服务小区对应第一反馈比特的比特数;在另一个示例中,第一反馈信息的比特数包括:m*n个第一反馈比特的比特数,m个服务小区中每个服务小区对应n个第一反馈比特的比特数,n为正整数。其中,第一反馈比特的比特数等于1,或者,第一反馈比特的比特数为大于1的整数。
示例性地,如下述表二所示,网络设备为终端设备配置了3个服务小区,分别为服务小区1、服务小区2和服务小区3。假设终端设备在同一PUCCH资源上,向网络设备上报第一反馈信息和HARQ-ACK码本,且假设一个第一反馈信息占用的比特数为x比特(x为正整数)、一个服务小区对应于一个第一反馈信息,则终端设备可以在PUCCH 1和PUCCH 2上传输的HARQ-ACK码本后均预留3*x比特,以用于承载3个服务小区分别对应的第一反馈信息。可选地,这3个x比特按照服务小区索引的大小依次(从小到大或从大到小)在HARQ-ACK码本中排列。应理解,在该示例中,第一PDSCH对应的至少一个PDSCH包括:HARQ-ACK码本对应的PDSCH中,服务小区索引相同的PDSCH。
如下述表二所示,PUCCH 1上传输的HARQ-ACK码本对应于PDSCH 1至PDSCH 6的HARQ-ACK信息,PUCCH 2上传输的HARQ-ACK码本对应于PDSCH 7至PDSCH 11的HARQ-ACK信息。以PUCCH 1上传输的HARQ-ACK码本为例,终端设备在PDSCH 1至PDSCH 6对应的HARQ-ACK信息后,预留3*x比特,每x比特用于承载一个第一反馈信息。其中,第一x比特对应于服务小区1,用于承载PDSCH 1和/或PDSCH 5对应的第一反馈信息;第二x比特对应于服务小区2,用于承载PDSCH 2和/或PDSCH 3和/或PDSCH 6对应的第一反馈信息;第三x比特对应于服务小区3,用于承载PDSCH 4对应的第一反馈信息。
表二 HARQ-ACK码本对应的PDSCH
服务小区1 PDSCH 1 / PDSCH 5 / PDSCH 7 PDSCH 10 /
服务小区2 PDSCH 2 PDSCH 3 PDSCH 6 PUCCH 1 PDSCH 8 / PUCCH 2
服务小区3 / PDSCH 4 / / PDSCH 9 PDSCH 11 /
当然,除了上述实施例中所述的至少一个PDSCH可以是一段时间段内的PDSCH,也可以是HARQ-ACK码本对应的PDSCH之外,至少一个PDSCH还可以由其它方式确定。下面,示出了几种确定至少一个PDSCH的其它方式。
在一个示例中,第一PDSCH为至少一个PDSCH中的PDSCH(或者说第一PDSCH包含在至少一个PDSCH中);承载至少一个PDSCH对应的HARQ-ACK信息的上行信道的优先级索引相同,该优先级索引可以为上述介绍说明的priority index 0或priority index 1;和/或,至少一个PDSCH对应的MCS表格相同,该MCS表格可以是上述介绍说明的256QAM、64QAM或lowSE64QAM。
在另一个示例中,第一PDSCH为至少一个PDSCH中的PDSCH(或者说第一PDSCH包含在至少一个PDSCH中);至少一个PDSCH不包括占用的PRB的数量小于第一值的PDSCH,也即,对应于宽带第一反馈信息的上报;和/或,至少一个PDSCH不包括占用的PRB与第一带宽重叠小于第二值的PDSCH,也即,对应于子带第一反馈信息的上报,例如,可以 将一个服务小区激活BWP划分为多个第一带宽,对应于每个第一带宽上报一个第一反馈信息。
当然,本申请实施例中,确定至少一个PDSCH的多种方式之间也可以组合使用。例如,至少一个PDSCH可以包括:等于或晚于第三时刻且早于或等于第一时刻的PDSCH中,承载对应的HARQ-ACK信息的上行信道的优先级索引相同的PDSCH。又例如,至少一个PDSCH可以包括:第一HARQ-ACK码本对应的PDSCH中,承载对应的HARQ-ACK信息的上行信道的优先级索引相同的PDSCH。再例如,至少一个PDSCH可以包括:等于或晚于第三时刻且早于或等于第一时刻的PDSCH中,对应的MCS表格相同的PDSCH。还例如,至少一个PDSCH可以包括:第一HARQ-ACK码本对应的PDSCH中,对应的MCS表格相同的PDSCH。应理解,基于本申请实施例提供的确定至少一个PDSCH的多种方式,所有能够实现确定至少一个PDSCH的组合方式,均应属于本申请的保护范围。
综上所述,本申请实施例提供的技术方案,通过提供了多种确定反馈信息对应的至少一个PDSCH的方式,以确保为网络设备提供相似调度参考信息,提升了终端设备确定至少一个PDSCH的灵活性。并且,由于不同服务小区的信道质量和/或信道特性差异可能较大,本申请实施例中,通过在每个HARQ-ACK码本后为每个服务小区分别预留用于承载反馈信息的比特,既可以实现一次HARQ-ACK码本的上报即可使得网络设备获得多个服务小区的信道质量和/或信道特性,还可以实现通过HARQ-ACK码本上报时间窗隐式得到至少一个PDSCH的时间窗。另外,本申请实施例中,还通过显式地指示一段时间段或时间窗来确定至少一个PDSCH,能够更加适用于反馈信息与HARQ-ACK码本分别上报的情形,且时间窗的右边界可以复用PDSCH的处理时长来界定,还可以避免额外的处理时间的定义。
需要说明的一点是,上述实施例中,从终端设备与网络设备之间交互的角度,对本申请实施例提供的信息反馈方法进行了介绍说明。上述实施例中,有关终端设备执行的步骤,可以单独实现为终端设备侧的信息反馈方法;有关网络设备执行的步骤,可以单独实现为网络设备侧的信息反馈方法。
