Description

混合自动重传请求码本的确定方法及设备
相关申请的交叉引用
本申请主张在2019年11月8日在中国提交的中国专利申请号No.201911089029.0的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及移动通信技术领域,具体涉及一种混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)码本的确定方法及设备。
背景技术
为了节省网络下行控制信令开销,除了动态调度之外,新空口(New Radio,NR)系统还支持了半持续调度(Semi-persistent scheduling,SPS),其允许基站通过高层信令对用户进行SPS配置,并经过物理层的下行控制信息激活,以达到将无线资源周期性地分配给特定用户的目的,可见,半持续调度具有“一次调度,多次使用”的特点。NR系统中对SPS的配置是通过无线资源控制(Radio Resource Control,RRC)信令实现的。
相关技术中的NR系统的下行(downlink,DL)SPS支持的最小周期为10ms。而为了支持低业务时延,在增强的高可靠低时延通信(enhanced Ultra-Reliable and Low Latency Communications,eURLLC)中对DL SPS进行了增强,将SPS的周期缩短至1个时隙(slot)。
此外,终端收到SPS物理下行共享信道(Physical Downlink Shared Channel,PDSCH)后,需要针对SPS PDSCH是否解调正确向网络反馈HARQ反馈信息(HARQ-ACK),其中混合自动重传请求确认(HARQ-Acknowledgement,HARQ-ACK)的时域和频域资源确定方式如下:
频域资源:RRC信令通过参数n1PUCCH-AN配置PUCCH-ResourceId,用于确定物理上行控制信道(Physical Uplink Control Channel,PUCCH)频域资源;
时域资源:PDSCH到PUCCH的时序(timing)先由RRC信令通过参数 dl-DataToUL-ACK配置一组HARQ timing值,然后通过激活下行控制信息(activation DCI)中的PDSCH到HARQ的时序指示(PDSCH-to-HARQ timing indicator),来指示从RRC信令配置的一组HARQ timing值中选择其中一个。
NR系统支持半静态帧结构配置,具体可以通过高层信令(如RRC信令)配置的以下信息单元(Information Element,IE)进行配置:TDD-UL-DL-ConfigCommon和/或TDD-UL-DL-ConfigDedicated。NR系统还支持动态时隙格式指示(Slot Format Indicator,SFI)。即,可以通过RRC信令或下行控制信息(Downlink Control Information,DCI)将某些slot/某些符号配置或指示为上行、下行或灵活(flexible),当某些slot/某些符号被配置为下行或者指示为flexible时,将无法传输SPS PDSCH的HARQ-ACK。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例,然而应当理解,可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反,提供这些实施例是为了能够更透彻地 理解本公开,并且能够将本公开的范围完整的传达给本领域的技术人员。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的本申请的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。说明书以及权利要求中“和/或”表示所连接对象的至少其中之一。
本文所描述的技术不限于NR系统以及长期演进型(Long Time Evolution,LTE)/LTE的演进(LTE-Advanced,LTE-A)系统,并且也可用于各种无线通信系统,诸如码分多址(Code Division Multiple Access,CDMA)、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 Frequency-Division Multiple Access,SC-FDMA)和其他系统。术语“系统”和“网络”常被可互换地使用。CDMA系统可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio Access,UTRA)等无线电技术。UTRA包括宽带CDMA(Wideband Code Division Multiple Access,WCDMA)和其他CDMA变体。TDMA系统可实现诸如全球移动通信系统(Global System for Mobile Communication,GSM)之类的无线电技术。OFDMA系统可实现诸如超移动宽带(UltraMobile Broadband,UMB)、演进型UTRA(Evolution-UTRA,E-UTRA)、IEEE 802.21(Wi-Fi)、IEEE 802.16(WiMAX)、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信系统(Universal Mobile Telecommunications System,UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project,3GPP)的组织的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴 项目2”(3GPP2)的组织的文献中描述。本文所描述的技术既可用于以上提及的系统和无线电技术,也可用于其他系统和无线电技术。然而,以下描述出于示例目的描述了NR系统,并且在以下大部分描述中使用NR术语,尽管这些技术也可应用于NR系统应用以外的应用。
以下描述提供示例而并非限定权利要求中阐述的范围、适用性或者配置。可以对所讨论的要素的功能和布置作出改变而不会脱离本公开的精神和范围。各种示例可恰适地省略、替代、或添加各种规程或组件。例如,可以按不同于所描述的次序来执行所描述的方法,并且可以添加、省去、或组合各种步骤。另外,参照某些示例所描述的特征可在其他示例中被组合。
请参见图1,图1示出本公开实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络设备12。其中,终端11也可以称作用户终端或用户设备(User Equipment,UE),终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant,PDA)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备,需要说明的是,在本公开实施例中并不限定终端11的具体类型。网络设备12可以是基站和/或核心网网元,其中,上述基站可以是5G及以后版本的基站(例如:gNB、5G NR NB等),或者其他通信系统中的基站(例如:eNB、无线局域网(Wireless Local Area Network,WLAN)接入点、或其他接入点等),其中,基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇,需要说明的是,在本公开实施例中仅以NR系统中的基站为例,但是并不限定基站的具体类型。
基站可在基站控制器的控制下与终端11通信,在各种示例中,基站控制器可以是核心网或某些基站的一部分。一些基站可通过回程与核心网进行控制信息或用户数据的通信。在一些示例中,这些基站中的一些可以通过回程 链路直接或间接地彼此通信,回程链路可以是有线或无线通信链路。无线通信系统可支持多个载波(不同频率的波形信号)上的操作。多载波发射机能同时在这多个载波上传送经调制信号。例如,每条通信链路可以是根据各种无线电技术来调制的多载波信号。每个已调信号可在不同的载波上发送并且可携带控制信息(例如,参考信号、控制信道等)、开销信息、数据等。
基站可经由一个或多个接入点天线与终端11进行无线通信。每个基站可以为各自相应的覆盖区域提供通信覆盖。接入点的覆盖区域可被划分成仅构成该覆盖区域的一部分的扇区。无线通信系统可包括不同类型的基站(例如宏基站、微基站、或微微基站)。基站也可利用不同的无线电技术,诸如蜂窝或WLAN无线电接入技术。基站可以与相同或不同的接入网或运营商部署相关联。不同基站的覆盖区域(包括相同或不同类型的基站的覆盖区域、利用相同或不同无线电技术的覆盖区域、或属于相同或不同接入网的覆盖区域)可以交叠。
无线通信系统中的通信链路可包括用于承载上行链路(Uplink,UL)传输(例如,从终端11到网络设备12)的上行链路,或用于承载下行链路(Downlink,DL)传输(例如,从网络设备12到终端11)的下行链路。UL传输还可被称为反向链路传输,而DL传输还可被称为前向链路传输。下行链路传输可以使用授权频段、非授权频段或这两者来进行。类似地,上行链路传输可以使用有授权频段、非授权频段或这两者来进行。
如背景技术中所述的,相关技术中,终端可能在小区重选或接入后发生未预料到的小区无法接入、切片接入失败或切片服务质量(Quality of Service,QoS)回退等情况,这严重影响了用户体验,为解决以上问题中的至少一个,本公开实施例提供了一种混合自动重传请求码本的确定方法,可以减少或避免以上情况的发生,提高通信效率,改善用户体验。
从背景技术部分对相关技术的介绍可以看出,对于SPS PDSCH的HARQ-ACK反馈,其时序(timing)是通过RRC信令+activation DCI确定的,activation DCI一旦激活某个HARQ timing值,那么对所有SPS PDSCH,都是使用这个相同的HARQ timing值。
在DL SPS PDSCH的最小周期为10ms的情况下,即使每个SPS PDSCH 的HARQ timing相同,也还是能比较好的适配半静态帧结构的配置,将HARQ-ACK指示到可用的上行时隙(available UL slot)上。而当进一步将DL SPS PDSCH的周期缩短到1个时隙(slot)时,如图2所示,假设半静态帧结构被配置为DDDDU(D表示下行,U表示上行),时隙DL#1~DL#4均为下行时隙,UL#5为上行时隙。无论activation DCI中激活的HARQ timing(K1)是多少(图2中K1=1),都将有3个slot(如图2中的DL#1~DL#3)上的PDSCH的HARQ-ACK无处反馈。
假设无处反馈的HARQ-ACK可以推迟(postpone)到下一个可用(available)的UL slot上反馈,但是相关技术在确定HARQ-ACK码本时没有考虑到这个问题,即,在HARQ-ACK码本中并没有为这些PDSCH的HARQ-ACK留足比特,下面将针对采用半静态码本和动态码本的情况分别进行说明:
1)在半静态码本确定时,相关技术通过K1集合(K1 set)确定候选PDSCH接收机会(candidate PDSCH)的集合,若K1 set={1,2,3,4,5},而activation DCI中指示的K1=4,那么,如图3所示,下行时隙DL#2~4的PDSCH的HARQ-ACK将会推迟(postpone)到第2个UL时隙上反馈。而第2个UL时隙在确定HARQ-ACK码本时,并没有为下行时隙DL#2~4的PDSCH的HARQ-ACK留出比特位置,因此在第2个UL时隙上传输的HARQ-ACK码本(codebook)就会出现预留的比特数不够的问题。
2)在动态码本确定时,相关技术对SPS PDSCH的HARQ-ACK处理方式为:在码本的最后预留1个比特,用于传输SPS PDSCH的HARQ-ACK。但是当DL SPS PDSCH周期缩短到1个slot后,如图2,若K1=1,那么下行时隙DL#1~3的PDSCH都需要推迟(postpone)到UL#5来反馈HARQ-ACK,所以在UL slot#5传输的HARQ-ACK码本就会出现预留的比特数不够的问题。
为解决上述问题中的至少一个,本公开实施例提出了一种混合自动重传请求(HARQ)码本的确定方法,在半静态码本以及动态码本的确定中,通过扩大K1集合和候选PDSCH接收机会集合以及冗余反馈的方式,解决了由于SPS PDSCH HARQ-ACK推迟所导致的HARQ-ACK码本比特数不够的问题, 避免了SPS PDSCH不必要的重传,提升了频谱效率。
下面首先介绍在采用半静态码本时本公开实施例如何确定HARQ-ACK码本。
本公开实施例提供的半静态HARQ-ACK码本的确定方法,可以应用于终端或基站,用于确定半持续调度物理下行共享信道(SPS PDSCH)的HARQ-ACK码本。下面以终端为例进行说明。请参照图4,本公开实施例的半静态HARQ-ACK码本的确定方法在应用于终端侧时,包括:
步骤41,终端根据第一信息,确定候选PDSCH接收机会的第一集合。
这里,其中,所述第一信息可以包括以下信息中的至少一种:
A)一组时隙时序值或子时隙时序值K 1,1,K 1,2,…K 1,N用于表示从PDSCH到HARQ-ACK的时序。
这里,所述一组时隙时序值或子时隙时序值可以是预先定义的,还可以是基站通过高层信令配置给所述终端的。具体的,所述一组时隙时序值或子时隙时序值可以是相关技术中基站所配置的K1集合(K1 set)。
B)第一配置信息,所述第一配置信息包括小区级或用户级的上下行配置信息。
这里,所述第一配置信息具体可以包括:基站通过高层信令(如RRC信令)配置的以下信息单元(IE):TDD-UL-DL-ConfigurationCommon和/或TDD-UL-DL-ConfigDedicated。其中,TDD-UL-DL-ConfigurationCommon也可以称作时分双工-上行-下行公共配置,TDD-UL-DL-ConfigDedicated也可以称作时分双工-上行-下行专用配置。当然,本公开实施例基站还可以利用其他相关技术中的IE或新定义的配置参数,来作为所述第一配置信息,本公开实施例对此不做具体限定。
步骤42,终端根据所述第一集合,确定第一上行时隙或子时隙n的PUCCH资源上传输的HARQ-ACK信息或HARQ-ACK码本。
这里,针对所述第一集合中的每个PDSCH接收机会,在所述HARQ-ACK信息中保留至少一个用于反馈所述PDSCH接收机会对应的HARQ-ACK的比特,从而得到所述第一集合对应的HARQ-ACK码本,即第一上行时隙或子时隙n的PUCCH资源上传输的HARQ-ACK信息。
通过以上步骤,本公开实施例根据所述第一信息来确定候选PDSCH接收机会的第一集合,扩大了候选PDSCH接收机会集合,这样,本公开实施例在确定第一上行时隙或子时隙n的半静态码本时,不仅包含相关技术中已经含有的HARQ-ACK比特,还包含了SPS PDSCH对应的HARQ-ACK推迟到第一上行时隙或子时隙n上的HARQ-ACK比特,从而在确定HARQ-ACK码本时可以引入更多的冗余比特,解决了由于SPS PDSCH HARQ-ACK推迟所导致的HARQ-ACK码本比特数不够的问题,避免了SPS PDSCH不必要的重传,提升了频谱效率。
具体的,上述步骤41中,确定候选PDSCH接收机会的第一集合可以有不同的实现方式,下面将详细说明。
方式1:终端可以对所述一组时隙时序值或子时隙时序值中的每个时序值K 1,i,确定一个第二时序值集合{K 1,i,K 1,i+1,…,K 1,i+T-1},得到多个第二时序值集合,其中,所述T为第一周期;然后,确定包括所述多个第二时序值集合中的所有时序值的第一时序值集合;然后,根据第一时序值集合,确定候选PDSCH接收机会的第一集合。
方式2:终端可以根据第一时序值集合,确定候选PDSCH接收机会的第一集合,其中,所述第一时序值集合中的时序值属于以下集合的至少一个:{K 1,i,K 1,i+1,…,K 1,i+T-1},i=1…N,N为所述一组时隙时序值或子时隙时序值所包含的时序值总数,所述T为第一周期。
方式3:根据第一时序值集合,确定候选PDSCH接收机会的第一集合;其中,所述第一时序值集合包括从min{K 1,i}到max{K 1,i+T-1}的所有正整数,所述T为第一周期。
以上各个方式中,所述第一周期T可以是预先约定的;或者,所述第一周期T可以是基站通过高层信令配置给终端的;或者,所述第一周期T可以是终端根据第一配置信息确定的。所述第一周期T可以是整数,另外,不同的子载波间隔对应的第一周期可以相同或不同。可选的,所述第一周期可以是上下行转换周期。
在以上各个方式中,根据第一时序值集合,确定候选PDSCH接收机会的第一集合,具体可以包括:遍历所述第一时序值集合中的每个时序值K 1,X, 根据时序值K 1,X,确定第一上行时隙或子时隙n对应的至少一个第一下行时隙,并根据所述上下行配置信息,判断所述第一下行时隙是否存在某一时域资源分配,所述某一时域资源分配中的每一个符号都未被所述上下行配置信息配置为上行,若存在,则在所述第一集合中加入至少一个候选PDSCH接收机会;其中,所述某一时域资源分配为基站通过高层信令配置的,或者预先约定的。
通过以上实现方式,本公开实施例将相关技术的K1集合扩大为所述第一时序值集合,通过增加时序值,从而在后续基于所述第一时序值集合,确定候选PDSCH接收机会的第一集合时,扩充了候选PDSCH接收机会,这样,在步骤42中基于所述第一集合确定码本时加入更多的码本比特,解决了相关技术由于SPS PDSCH HARQ-ACK推迟等原因所导致的HARQ-ACK码本比特数不够的问题,避免了SPS PDSCH不必要的重传,提升了频谱效率。
本公开实施例还可以针对某个上行时隙或子时隙(为了便于描述,下文称之为目标上行时隙或子时隙),按照以下至少一种方式,确定所述目标上行时隙或子时隙是否为用于传输HARQ-ACK信息的第一上行时隙或子时隙n:
方式a)若所述目标上行时隙或子时隙未包括任一目标PUCCH资源,则确定所述目标上行时隙或子时隙不是所述第一上行时隙或子时隙n;
方式b)若所述目标上行时隙或子时隙未包括任一所述目标PUCCH资源,且不存在SPS PDSCH接收满足第一条件,则确定所述目标上行时隙不是所述第一上行时隙或子时隙n;
方式c)若所述目标上行时隙或子时隙未包括任一目标PUCCH资源,且存在SPS PDSCH接收满足所述第一条件,则确定所述目标上行时隙或子时隙为所述第一上行时隙或子时隙n,且使用基站通过高层信令为所述SPS PDSCH配置的PUCCH资源传输HARQ-ACK码本;
方式d)若所述目标上行时隙或子时隙包括任一所述目标PUCCH资源,且不存在SPS PDSCH接收满足所述第一条件,则确定所述目标上行时隙不是所述第一上行时隙或子时隙n。
其中,所述目标PUCCH资源是由下行控制信息包括的PDSCH到HARQ的HARQ反馈时序指示(PDSCH-to-HARQ-feedback timing indicator)以及 PUCCH资源指示(PUCCH resource indicator)所指示的PUCCH资源;所述第一条件为SPS PDSCH对应的HARQ反馈(HARQ-ACK)资源中的至少一个符号被配置或指示成了下行或者灵活(flexible),且所述HARQ-ACK资源之后最近的上行时隙或子时隙为所述目标上行时隙或子时隙。
在确定了所述目标上行时隙或子时隙是用于传输HARQ-ACK信息的第一上行时隙或子时隙n时,本公开实施例可以按照步骤41~42的方式确定在所述目标上行时隙或子时隙传输的HARQ-ACK信息(即所确定的HARQ-ACK码本)。而在确定了所述目标上行时隙或子时隙不是用于传输HARQ-ACK信息的第一上行时隙或子时隙n时,本公开实施例则可以不对所述的一组时隙时序值或子时隙时序值,即不对K1集合(K1 set)进行更新,而是直接根据K1集合,确定候选PDSCH接收机会的第一集合,进而根据所确定的第一集合,确定所述目标上行时隙或子时隙上传输的HARQ-ACK信息或HARQ-ACK码本。
仍然以图3为例,假设基站通过高层信令配置K1 set={1,2,3,4},上下行转换周期T=5,那么终端在确定半静态码本需要确定的比特数时,将K1 set更新为{1,1+5-1},{2,2+5-1}…{4,4+5-1},然后确定上述各个集合的并集,从而得到更新后的K1 set为{1,2,3,4,5,6,7,8}。终端遍历更新后的K1 set中的每一个K 1,x,根据所述K 1,x以及上下行子载波间隔确定上行时隙UL#5所对应的下行时隙,然后在所述下行时隙内,判断时域资源分配表格中的每一行时域资源分配,若存在某一时域资源分配的行,其中每一个符号(symbol)都没有被半静态帧结构配置(如TDD-UL-DL-ConfigurationCommon和/或TDD-UL-DL-ConfigDedicated)信息配置为了上行,则为所述下行时隙保留至少1个比特,用于反馈HARQ-ACK。
请参照图5,本公开实施例提供的半静态HARQ-ACK码本的确定方法,在应用于基站侧时,包括:
步骤51,基站根据第一信息,确定候选PDSCH接收机会的第一集合。
这里,其中,所述第一信息可以包括以下信息中的至少一种:
A)一组时隙时序值或子时隙时序值K 1,1,K 1,2,…K 1,N用于表示从PDSCH到HARQ-ACK的时序。
这里,所述一组时隙时序值或子时隙时序值可以是预先定义的,还可以是基站通过高层信令配置给终端的。具体的,所述一组时隙时序值或子时隙时序值可以是相关技术中基站所配置的K1集合(K1 set)。
B)第一配置信息,所述第一配置信息包括小区级或用户级的上下行配置信息。
这里,所述第一配置信息具体可以包括:基站通过高层信令(如RRC信令)配置的以下信息单元(IE):TDD-UL-DL-ConfigurationCommon和/或TDD-UL-DL-ConfigDedicated。其中,TDD-UL-DL-ConfigurationCommon也可以称作时分双工-上行-下行公共配置,TDD-UL-DL-ConfigDedicated也可以称作时分双工-上行-下行专用配置。当然,本公开实施例基站还可以利用其他相关技术中的IE或新定义的配置参数,来作为所述第一配置信息,本公开实施例对此不做具体限定。
步骤52,基站根据所述第一集合,确定第一上行时隙或子时隙n的PUCCH资源上接收的HARQ-ACK信息或HARQ-ACK码本。
这里,针对所述第一集合中的每个PDSCH接收机会,在所述HARQ-ACK信息中保留至少一个用于反馈所述PDSCH接收机会对应的HARQ-ACK的比特,从而得到所述第一集合对应的HARQ-ACK码本,即第一上行时隙或子时隙n的PUCCH资源上传输的HARQ-ACK信息。
本公开实施例的半静态HARQ-ACK码本确定方法在基站侧实施时的更多细节,可以参考前文在终端侧实施时的具体描述,为节约篇幅,此处不再赘述。
以上介绍了本公开实施例的半静态码本的确定方法。下面进一步介绍动态码本确定方法。
请参照图6,本公开实施例提供的动态码本的确定方法,可以应用于终端或基站,用于确定半持续调度物理下行共享信道(SPS PDSCH)的HARQ-ACK码本。下面以终端为例进行说明。请参照图6,本公开实施例的动态HARQ-ACK码本的确定方法在应用于终端侧时,包括:
步骤61,确定N比特的第一HARQ-ACK信息,所述第一HARQ-ACK信息至少包括用于反馈下行控制信息DCI所调度的PDSCH和/或半持续调度 物理下行共享信道释放SPS PDSCH release的HARQ-ACK信息。
这里,确定N比特的第一HARQ-ACK信息,具体可以包括:根据一组时隙时序值或子时隙时序值和时隙偏移值,确定PDCCH检测机会集合;根据所述PDCCH检测机会集合检测下行控制信息(DCI),并根据检测到的DCI中的累计数据分配指示(counter Data Assignment Indication,counter DAI)以及总数据分配指示(total Data Assignment Indication,total DAI),构建出所述N比特HARQ-ACK信息。
其中,所述一组时隙时序值或子时隙时序值,用于表示从PDSCH到HARQ-ACK的时序,具体可以是预先定义的,还可以是基站通过高层信令配置给所述终端的。例如,所述一组时隙时序值或子时隙时序值可以是相关技术中基站所配置的K1集合(K1 set)。所述时隙偏移值为下行控制信息中包含的时域资源分配域指示的,用于表示PDCCH到PDSCH的时序。
步骤62,若在第一集合内收到激活的M个目标SPS PDSCH,则在所述第一HARQ-ACK信息后,添加M比特用于传输目标SPS PDSCH的HARQ-ACK信息,得到第一上行时隙或子时隙n的PUCCH资源上传输的HARQ-ACK信息。
这里,所述目标SPS PDSCH属于同一个激活的SPS配置。所述第一集合为从时隙n-K 1,c-T+1到时隙n-K 1,c的所有时隙,或者,所述第一集合为从时隙n-K 1,c-T+1到时隙n-K 1,c的所有下行时隙。
所述K 1,c为SPS PDSCH对应的PDSCH到HARQ反馈时序值(PDSCH-to-HARQ-feedback timing value),所述T为第一周期。
所述第一周期T可以是预先约定的;或者,所述第一周期T可以是基站通过高层信令配置给终端的;或者,所述第一周期T可以是终端根据第一配置信息确定的。所述第一周期T可以是整数,另外,不同的子载波间隔对应的第一周期可以相同或不同。可选的,所述第一周期可以是上下行转换周期。
通过以上步骤,在确定动态HARQ-ACK码本时,本公开实施例在N比特的第一HARQ-ACK信息后,添加了M比特,用于传输目标SPS PDSCH的HARQ-ACK信息,对相关技术中的动态码本的长度进行了扩展,从而通过增加冗余反馈信息,解决了相关技术由于SPS PDSCH HARQ-ACK推迟所导致 的HARQ-ACK码本比特数不够的问题,避免了SPS PDSCH不必要的重传,提升了频谱效率。
在实际应用中,终端可能存在多个激活的SPS配置,此时,在上述步骤62中,当激活了多个SPS配置时,所述第一集合可以包括从时隙n-K 1,c,p-T+1到时隙n-K 1,c,p的所有时隙,或者,所述第一集合包括从时隙n-K 1,c,p-T+1到时隙n-K 1,c,p的所有下行时隙。
这里,所述K 1,c,p为第p个SPS配置的SPS PDSCH对应的PDSCH到HARQ反馈时序值PDSCH-to-HARQ-feedback timing value,所述T为第一周期。
类似的,本公开实施例还可以针对某个上行时隙或子时隙(为了便于描述,下文称之为目标上行时隙或子时隙),按照以下至少一种方式,确定所述目标上行时隙或子时隙是否为用于传输HARQ-ACK信息的第一上行时隙或子时隙n:
方式a)若所述目标上行时隙或子时隙未包括任一目标PUCCH资源,则确定所述目标上行时隙或子时隙不是所述第一上行时隙或子时隙n;
方式b)若所述目标上行时隙或子时隙未包括任一所述目标PUCCH资源,且不存在SPS PDSCH接收满足第一条件,则确定所述目标上行时隙不是所述第一上行时隙或子时隙n;
方式c)若所述目标上行时隙或子时隙未包括任一目标PUCCH资源,且存在SPS PDSCH接收满足所述第一条件,则确定所述目标上行时隙或子时隙为所述第一上行时隙或子时隙n,且使用基站通过高层信令为所述SPS PDSCH配置的PUCCH资源传输HARQ-ACK码本;
方式d)若所述目标上行时隙或子时隙包括任一所述目标PUCCH资源,且不存在SPS PDSCH接收满足所述第一条件,则确定所述目标上行时隙不是所述第一上行时隙或子时隙n。
其中,所述目标PUCCH资源是由下行控制信息包括的PDSCH到HARQ的HARQ反馈时序指示(PDSCH-to-HARQ-feedback timing indicator)以及PUCCH资源指示(PUCCH resource indicator)所指示的PUCCH资源;所述第一条件为SPS PDSCH对应的HARQ反馈(HARQ-ACK)资源中的至少一 个符号被配置或指示成了下行或者灵活(flexible),且所述HARQ-ACK资源之后最近的上行时隙或子时隙为所述目标上行时隙或子时隙。
在确定了所述目标上行时隙或子时隙是用于传输HARQ-ACK信息的第一上行时隙或子时隙n时,本公开实施例可以按照步骤61~62的方式确定在所述目标上行时隙或子时隙接收的HARQ-ACK信息(即所确定的HARQ-ACK码本)。而在确定了所述目标上行时隙或子时隙不是用于传输HARQ-ACK信息的第一上行时隙或子时隙n时,本公开实施例则可以直接执行步骤61,将步骤61得到的N比特的第一HARQ-ACK信息,作为所述目标上行时隙或子时隙上接收的HARQ-ACK信息。
仍然以图3为例,若K1 set={1,2,3,4,5},而激活DCI(activation DCI)中指示的K1=4,则在上行时隙UL#10上反馈的HARQ-ACK码本,包含DL#2到DL#6所传输的SPS PDSCH对应的HARQ-ACK信息,这样,可以为DL#2~DL#6在UL#10保留了传输反馈信息的比特位。
请参照图7,本公开实施例的动态HARQ-ACK码本的确定方法在应用于基站侧时,包括:
步骤71,基站确定N比特的第一HARQ-ACK信息,所述第一HARQ-ACK信息至少包括用于反馈下行控制信息DCI所调度的PDSCH和/或半持续调度物理下行共享信道释放SPS PDSCH release的HARQ-ACK信息。
步骤72,若在第一集合内收到激活的M个目标SPS PDSCH,则在所述第一HARQ-ACK信息后,添加M比特用于传输目标SPS PDSCH的HARQ-ACK信息,得到第一上行时隙或子时隙n的PUCCH资源上接收的HARQ-ACK信息。
这里,所述目标SPS PDSCH属于同一个激活的SPS配置。所述第一集合为从时隙n-K 1,c-T+1到时隙n-K 1,c的所有时隙,或者,所述第一集合为从时隙n-K 1,c-T+1到时隙n-K 1,c的所有下行时隙。所述K 1,c为SPS PDSCH对应的PDSCH到HARQ反馈时序值(PDSCH-to-HARQ-feedback timing value),所述T为第一周期。
而在激活多个SPS配置时,所述第一集合可以包括从时隙n-K 1,c,p-T+1到时隙n-K 1,c,p的所有时隙,或者,所述第一集合包括从时隙n-K 1,c,p-T+1到时 隙n-K 1,c,p的所有下行时隙。
这里,所述K 1,c,p为第p个SPS配置的SPS PDSCH对应的PDSCH到HARQ反馈时序值PDSCH-to-HARQ-feedback timing value,所述T为第一周期。
本公开实施例的动态HARQ-ACK码本确定方法在基站侧实施时的更多细节,可以参考前文在终端侧实施时的具体描述,为节约篇幅,此处不再赘述。
在本公开实施例中,在确定半静态或动态码本时,在至少两个不同优先级的PUCCH和PUSCH冲突时,可以先忽略(drop)低优先级与高优先级有重叠(overlap)的低优先级的上行传输(UL transmission),再判断PUCCH与PUSCH是否复用(multiplex)。
以上介绍了本公开实施例的各种方法。下面将进一步提供实施上述方法的装置。
