相关申请的交叉引用
本申请主张在2021年03月10日在中国提交的中国专利申请No.202110262602.4的优先权,其全部内容通过引用包含于此。
技术领域
本申请属于无线通信技术领域,具体涉及一种半静态HARQ-ACK码本的生成方法及终端。
背景技术
用户设备(User Equipment,UE,也称为终端)在一个混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)反馈资源(物理上行控制信道(Physical Uplink Control Channel,PUCCH)或物理上行共享信道(Physical Uplink Shared Channel,PUSCH))上反馈的混合自动重传请求应答(Hybrid Automatic Repeat ReQuest Acknowledgement,HARQ-ACK)信息的整体称为HARQ-ACK码本。
半静态HARQ-ACK码本也叫做type 1HARQ-ACK codebook,其码本的大小与实际物理下行共享信道(Physical Downlink Shared CHannel,PDSCH)调度或物理下行控制信道(Physical downlink control channel,PDCCH)传输情况无关,由无线资源控制(Radio Resource Control,RRC)配置或预定义的参数来确定。当RRC参数pdsch-HARQ-ACK-Codebook=semi-static,即配置为半静态HARQ-ACK码本。
半静态HARQ-ACK码本的生成方法包括以下步骤:
1)确定与激活上行带宽部分(Uplink bandwidth Part,UL BWP)关联的K 1集合;
K 1是确定HARQ-ACK码本重要的参数之一,指的是物理下行共享信道和其对应的反馈资源(PUCCH/PUSCH)之间的时隙或子时隙偏移值。对于某 一个PDSCH对应的K 1,k值,由RRC配置或预定义可能的集合,然后通过PDSCH的相应调度下行控制信息(Downlink Control Information,DCI)信息的域指示可能的集合中的一个值。其中,K 1,k是K 1集合中的值,k=0……M-1,M为与激活UL BWP关联的K 1集合中的元素个数,即K 1集合的基或K 1集合的基数。
2)根据与激活UL BWP关联的K 1集合,确定候选PDSCH接收时机。
具体的,针对与激活UL BWP关联的K 1集合的每个K 1,k值,根据PDSCH对应的时域资源分配(Time Domain Resource Assignment,TDRA)表格,确定所述K 1,k值对应的时隙内的候选PDSCH接收时机。
3)根据候选PDSCH接收时机,确定半静态HARQ-ACK码本。
当UE支持两种类型的PDSCH同时传输业务时,两种类型的PDSCH的TDRA表格和/或K 1集合可以单独配置。而,此时如何确定半静态HARQ-ACK码本是需要解决的技术问题。

图1示出本申请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和网络侧设备12。其中,终端11也可以称作终端设备或者用户终端(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)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备,可穿戴式设备包括:手环、耳机、眼镜等。需要说明的是,在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网,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、无线局域网络(Wireless Local Area Networks,WLAN)接入点、无线保真(Wireless Fidelity,WiFi)节点、发送接收点(Transmitting Receiving Point,TRP)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,在本申请实施例中仅以NR系统中的基站为例,但是并不限定基站的具体类型。
下面结合附图,通过具体的实施例及其应用场景对本申请实施例提供的半静态HARQ-ACK码本的生成方法及终端进行详细地说明。
请参考图2,图2为本申请实施例的半静态HARQ-ACK码本的生成方法,由终端执行,包括:
步骤21:根据第一PDSCH对应的K 1集合和第二PDSCH对应的K 1集合中的至少一项,确定与激活UL BWP关联的K 1集合;
步骤22:针对与激活UL BWP关联的K 1集合中的每个K 1,k值,根据所述第一PDSCH对应的TDRA表格和所述第二PDSCH对应的TDRA表格中的至少一项,确定所述K 1,k值对应的时隙内的候选PDSCH接收时机,其中,k=0,……M-1,M为所述与激活UL BWP关联的K 1集合中的元素个数;
本申请实施例中,根据与激活UL BWP关联的K 1集合,可以确定一个HARQ-ACK反馈窗,即对于某个UL时隙,需要反馈的PDSCH或PDCCH(如指示SPS PDSCH release的PDCCH或者指示Scell dormancy的PDCCH等)在且只能在HARQ-ACK反馈窗内的时隙传输,或者说,该UL时隙只需要反馈HARQ-ACK反馈窗内的传输的PDSCH或PDCCH。
请参考图3,假设与激活UL BWP关联的K 1集合为{5,6,7},则n+9时隙对应的HARQ-ACK反馈窗为:n+4到n+2,其中,n+2与n+9的偏移值K 1,k为7,n+3与n+9的偏移值K 1,k为6,n+4与n+9的偏移值K 1,k为5。
步骤23:根据所述候选PDSCH接收时机确定半静态HARQ-ACK码本。
本申请实施例中,明确了终端支持第一PDSCH和第二PDSCH同时传输时,半静态HARQ-ACK码本的确定方式,能够优化半静态HARQ-ACK码本的确定方式。
本申请实施例中,可选的,根据第一PDSCH对应的K 1集合和第二PDSCH对应的K 1集合中的至少一项,确定与激活UL BWP关联的K 1集合包括以下之一:
1)使用所述第一PDSCH对应的K 1集合作为所述与激活UL BWP关联的K 1集合;
可选的,第二PDSCH对应的K 1集合是所述第一PDSCH对应的K 1集合的子集。
2)使用所述第二PDSCH对应的K 1集合作为所述与激活UL BWP关联的K 1集合;
可选的,第一PDSCH对应的K 1集合是所述第二PDSCH对应的K 1集合的子集。
3)使用所述第一PDSCH对应的K 1集合和所述第二PDSCH对应的K 1集合的合集作为所述与激活UL BWP关联的K 1集合。
本申请实施例中,明确了终端支持第一PDSCH和第二PDSCH同时传输时,与激活UL BWP关联的K 1集合的确定方式。
本申请实施例中,可选的,根据所述第一PDSCH对应的TDRA表格和所述第二PDSCH对应的TDRA表格中的至少一项,确定所述K 1,k值对应的时隙内的候选PDSCH接收时机包括以下至少一项:
若所述K 1,k值属于所述第一PDSCH对应的K 1集合和第二PDSCH对应的K 1集合的交集,根据所述第一PDSCH对应的TDRA表格的行索引和所述第二PDSCH对应的TDRA表格的行索引的合集,确定所述K 1,k值对应时隙内的候选PDSCH接收时机;
若所述K 1,k值不属于所述交集,根据所述第一PDSCH对应的TDRA表格的行索引或者所述第二PDSCH对应的TDRA表格的行索引,确定所述K 1,k值 对应时隙内的候选PDSCH接收时机。
本申请实施例中,只有在与激活UL BWP关联的K 1集合中的K 1,k值属于所述第一PDSCH对应的K 1集合和第二PDSCH对应的K 1集合的交集时,才使用第一PDSCH对应的TDRA表格和第二PDSCH对应的TDRA表格的合集,确定该K 1,k值对应的时隙内的候选PDSCH接收时机,在K 1,k值不属于所述交集时,只使用第一PDSCH对应的TDRA表格或者第二PDSCH对应的TDRA表格,确定该K 1,k值对应的时隙内的候选PDSCH接收时机,从而可以有效减小半静态HARQ-ACK码本的大小。
本申请实施例中,可选的,若所述K 1,k值不属于所述交集,根据所述第一PDSCH对应的TDRA表格的行索引或者所述第二PDSCH对应的TDRA表格的行索引,确定所述K 1,k值对应时隙内的候选PDSCH接收时机包括以下至少一项:
若所述K 1,k值属于所述第一PDSCH对应的K 1集合,根据所述第一PDSCH对应的TDRA表格的行索引,确定所述K 1,k值对应时隙内的候选PDSCH接收时机;
若所述K 1,k值属于所述第二PDSCH对应的K 1集合,根据所述第二PDSCH对应的TDRA表格的行索引,确定所述K 1,k值对应时隙内的候选PDSCH接收时机。
本申请实施例中,如果UE配置了子时隙(sub-slot),例如配置了subslotLengthForPUCCH,则上述实施例中的时隙可以被子时隙替代,例如确定K 1,k值对应的子时隙内的候选PDSCH接收时机。
本申请的上述实施例中,可选的,所述第一PDSCH和第二PDSCH对应的TDRA表格和/或K 1集合不同。
本申请的上述实施例中,可选的,所述第一PDSCH为单播PDSCH,所述第二PDSCH为组播PDSCH。
值得注意的是,本发明中第一PDSCH和第二PDSCH分别代表两类不同的PDSCH,如组播PDSCH和单播PDSCH,高优先级PDSCH和低优先级 PDSCH等。终端可以通过调度PDSCH的DCI格式、DCI所在的控制资源集(CORESET)、DCI所在的搜索空间,PDSCH的加扰RNTI或加扰调度PDSCH的DCI的CRC的RNTI等方式确定第一PDSCH或第二PDSCH。本发明对此不作具体限定。
目前,新无线(New Radio,NR)技术引入广播/多播特性。广播多播业务主要通过组播PDSCH(也可以叫做多播PDSCH,或者组公共PDSCH)进行传输。UE可以同时接收组播PDSCH和单播PDSCH,且组播PDSCH和单播PDSCH的TDRA表格和/或K 1集合可以单独配置。当UE支持单播PDSCH和组播PDSCH同时传输时,如果直接根据单播PDSCH的TDRA和组播PDSCH的TDRA表格的合集确定候选PDSCH接收时机,会增加带来不必要的HARQ-ACK码本大小。因此,当UE支持单播PDSCH和组播PDSCH同时传输时,可以根据本申请上述各实施例记载的半静态HARQ-ACK码本的生成方法,来确定半静态HARQ-ACK码本,以优化半静态HARQ-ACK码本的确定方式。值得注意的是,这里支持单播PDSCH和组播PDSCH同时传输,是指支持两种业务传输,在一段时间内,UE既可以接收单播PDSCH,也可以接收组播PDSCH,并不代表单播PDSCH和组播PDSCH在重叠的时域符号上传输。
下面以所述第一PDSCH为单播PDSCH,所述第二PDSCH为组播PDSCH为例,对本申请实施例的半静态HARQ-ACK码本的生成方法进行说明。

请参考图5,图5为本申请实施例中的单播PDSCH对应的TDRA表格以及对应的候选PDSCH接收时机的示意图。请参考图6,图6为本申请实施例中的组播PDSCH对应的TDRA表格以及对应的候选PDSCH接收时机的示意 图。
假设步骤41中确定的与激活UL BWP关联的K 1集合为{1,2,3,4,5,6,7,8}。
若K 1,k值为6或8时,属于单播PDSCH对应的K 1集合和组播PDSCH对应的K 1集合的交集{6,8},终端根据单播PDSCH对应的TDRA表格和组播PDSCH对应的TDRA表格的合集,确定该K 1,k值对应的时隙内的候选PDSCH接收时机,请参考图7,图7为本申请实施例中的单播PDSCH和组播对应的TDRA表格的合集以及对应的候选PDSCH接收时机的示意图。
若K 1,k值属于{1,2,3,4,5,7},仅属于单播PDSCH对应的K 1集合,终端根据单播PDSCH对应的TDRA表格,确定所述K 1,k值对应时隙内的候选PDSCH接收时机。
若K 1,k值为10,仅属于组播PDSCH对应的K 1集合,终端根据组播PDSCH对应的TDRA表格,确定所述K 1,k值对应时隙内的候选PDSCH接收时机。
步骤43:根据所述候选PDSCH接收时机确定半静态HARQ-ACK码本。
本申请的上述实施例中,可选的,上述确定每个K 1,k值对应的时隙内的候选PDSCH接收时机还包括以下至少一项:
1)排除TDRA表格里和上行符号重叠的候选PDSCH接收时机。
即与时分复用(Time Division Duplexing,TDD)的上下行时隙格式配置进行比较,确定候选的PDSCH接收时机的位置为有效的。当TDRA的某一行的候选PDSCH接收位置与上行符号重叠时,则该行的候选的PDSCH接收时机的位置不是有效的接收机会,需被排除。
可选的,所述上行符号为半静态配置,如参数TDD-UL-DL-ConfigurationCommon和TDD-UL-DL-ConfigDedicated配置的上行符号。
2)对时域位置上重叠的候选PDSCH接收时机进行合并,例如只能生成1个HARQ-ACK比特(bit)。即根据下行BWP关联的TDRA表格,得到时域资源不重叠的行,对重叠的行只考虑其中1行。
举例来说,假设与激活UL BWP关联的K 1集合为{5,6,7}。并假设在 每个K 1,k对应的下行(Downlink,DL)时隙内,确定HARQ-ACK codebook的PDSCH的TDRA表格的各行都如图7所示。
对K 1,k=7的情况,请参考图8,假设所有的候选PDSCH接收时机都不和上行符号冲突(conflict),因此都可以保留。
对K 1,k=6的情况,请参考图9,假设行数为2,3,8的PDSCH候选位置和上行符号重叠,因此被排除。
对K 1,k=5的情况,假设所有的候选PDSCH接收时机集合都和上行符号重叠,因此都被排除。
从而最终确定的候选PDSCH接收时机集合为:MA,c={0,1,2,3,4,5,6,7,8}。
在确定候选的PDSCH接收时机之后,还需要确定HARQ-ACK信息,可以根据以下方式确定HARQ-ACK信息:
确定的候选PDSCH接收时机集合中没有调度的PDSCH reception,UE反馈NACK;
确定的候选PDSCH接收时机集合中没有指示到当前时隙反馈的PDSCH reception,UE反馈NACK;
若PDSCH的反馈窗口重叠,则在DCI格式1-0或DCI格式1-1指示的位置反馈,其他位置反馈NACK;
对有ACK/NACK反馈的候选PDSCH接收时机集合,根据获得的各小区候选PDSCH集合和RRC配置的小区个数、HARQ空间绑定参数、码块组(Code block group,CBG)配置参数和各小区支持的最大码字(codeword)参数,共同确定HARQ-ACK码本。
需要说明的是,本申请实施例提供的半静态HARQ-ACK码本的生成方法,执行主体可以为半静态HARQ-ACK码本的生成装置,或者,该半静态HARQ-ACK码本的生成装置中的用于执行半静态HARQ-ACK码本的生成的控制模块。本申请实施例中以半静态HARQ-ACK码本的生成装置执行半静态HARQ-ACK码本的生成方法为例,说明本申请实施例提供的半静态HARQ-ACK码本的生成装置。
