本申请实施例可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、先进的长期演进(Advanced long term evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、免授权频谱上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、免授权频谱上的NR(NR-based access to unlicensed spectrum,NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、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。

本申请实施例结合网络设备和终端设备描述了各个实施例,其中:终端设备也可以称为用户设备(User Equipment,UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置等。终端设备可以是WLAN中的站点(STAION,ST),可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及下一代通信系统,例如,NR网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)网络中的终端设备等。
作为示例而非限定,在本申请实施例中,该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备,是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称,如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上,或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备,更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能,例如:智能手表或智能眼镜等,以及只专注于某一类应用功能,需要和其它设备如智能手机配合使用,如各类进行体征监测的智能手环、智能首饰等。

在本申请实施例中,网络设备为小区提供服务,终端设备通过该小区使用的传输资 源(例如,频域资源,或者说,频谱资源)与网络设备进行通信,该小区可以是网络设备(例如基站)对应的小区,小区可以属于宏基站,也可以属于小小区(Small cell)对应的基站,这里的小小区可以包括:城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等,这些小小区具有覆盖范围小、发射功率低的特点,适用于提供高速率的数据传输服务。
在本申请实施例中,终端设备采用动态码本进行HARQ-ACK反馈,具体可以分为两种情况:
情况1:单载波场景。网络设备在向终端设备发送PDSCH时,会同时向终端设备发送DAI计数(counter DAI)信息,该DAI计数信息通过PDCCH发送给终端设备,用于终端设备确定HARQ反馈码本,即该DAI计数用于指示当前PDCCH调度的PDSCH是该HARQ反馈窗口内的第几个PDSCH,其中,PDSCH的排序方式是根据PDCCH的检测机会顺序排序的。为了减少DAI计数信息的比特数,可以使用取模的方式计数,例如,如果DAI计数的比特数为2比特,那么DAI计数的取值就模4;如果DAI计数的比特数为3比特,DAI计数的取值就模8。如图2所示,在HARQ-ACK反馈窗口内一共包括8个时隙,每个时隙上都配置有PDCCH检测机会,网络设备在该8个PDCCH检测机会中的第1、3、4、5、7个PDCCH检测机会上调度终端设备接收PDSCH,假设DAI计数的比特数为2比特,相应地,该5个时隙上的PDSCH对应的DAI计数分别为00,01,10,11,00。
对于每个PDSCH,其对应的HARQ-ACK反馈比特的大小K可以是高层配置的,例如,如果终端设备被调度的PDSCH中至少一个PDSCH支持2个码字,那么所有的PDSCH对应的HARQ-ACK比特都为2比特(K=2)。又例如,在支持基于码块组(Code block group,CBG)的反馈的情况下,假设一个PDSCH对应的最大HARQ-ACK比特数为8比特,所有PDSCH中每个PDSCH对应的HARQ-ACK比特数均为8比特(K=8)。
在图2的示例中,假设K=2,对应两个码字。当终端设备收到该5个PDSCH后,该终端设备可以确定该HARQ-ACK反馈窗口内的码本大小为10比特,如下表1所示:
表1
Figure PCTCN2018105495-appb-000001
当终端设备只收到5个PDSCH中的部分PDSCH,例如终端设备没有收到DAI计数为01的PDSCH,在这种情况下,在收到DAI计数为00的PDSCH后面收到了DAI计数为10的PDSCH,此时,终端设备可以判断自己丢掉了DAI计数为01的PDSCH,因此会在对应位置填充否定应答(Negative Acknowledgement,NACK),如下表2所示:
表2
Figure PCTCN2018105495-appb-000002
应理解,如果PDSCH中只有一个码字,那么码字1对应的HARQ-ACK反馈信息为NACK。
情况2:多载波场景。网络设备在向终端设备发送PDSCH时,会同时向终端设备发送DAI计数和DAI总数(total DAI)两个DAI信息,该两个DAI信息通过PDCCH发送给终端设备,用于终端设备确定HARQ反馈码本,其中,该DAI计数用于指示当前PDCCH调度的PDSCH是该HARQ反馈窗口内的第几个PDSCH,该DAI总数用于告诉终端设备该HARQ反馈窗口内截止到当前为止一共有多少个HARQ-ACK。PDSCH的排序方式 是根据PDCCH的检测机会顺序排序的,具体地,可以按照先频域后时域的顺序。为了减少DAI计数(或DAI总数)信息的比特数,可以使用取模的方式计数,例如,如果DAI计数(或DAI总数)的比特数为2比特,那么DAI计数(或DAI总数)的取值就模4;如果DAI计数(或DAI总数)的比特数为3比特,DAI计数(或DAI总数)的取值就模8。
如图3所示,终端设备被配置了2个载波,在HARQ-ACK反馈窗口内一共包括8个时隙,每个载波的每个时隙上都配置有PDCCH检测机会,那么PDCCH的检测机会排序为载波#1的第1个时隙,载波#2的第1个时隙,载波#1的第2个时隙,载波#2的第2个时隙,…,载波#1的第8个时隙,载波#2的第8个时隙。网络设备在该16个PDCCH检测机会中的第1、2、6、7、8、9、13、14个时隙上调度终端设备接收PDSCH,假设DAI计数和DAI总数的比特数分别为2比特,相应地,该8个时隙上的PDSCH对应的DAI计数和DAI总数如图3所示。
在图3的示例中,假设K=2,对应两个码字。假设终端设备没有收到第4个时隙上的PDSCH,该终端设备可以确定该HARQ-ACK反馈窗口内的码本如下表3所示:
表3
Figure PCTCN2018105495-appb-000003
应理解,PDCCH调度的PDSCH可以和PDCCH在同一个时隙上,也可以不和PDCCH在同一个时隙上,本申请实施例并不限定。
应理解,在非授权频段上,如图4所示,HARQ-ACK反馈窗口可以是根据网络设备抢占到信道之后才确定的,是一个动态的反馈窗口,例如,HARQ-ACK反馈窗口的起始位置为一个COT的起始位置,然而,由于被调度的PDSCH是提前准备的,因此,可能出现一个HARQ-ACK反馈窗口内的第一个PDCCH的检测机会中的DAI计数不为“00”的情况。另外,HARQ-ACK反馈窗口的起始位置可以是在后续的时频资源上指示的,因此,在后续指示的时候也可能出现窗口内的第一个PDCCH的检测机会中的DAI计数信息不为“00”的情况。在出现上述情况时,需要作出对应的规定,以使网络设备和终端设备对于HARQ-ACK码本的认知一致。
图5是根据本申请实施例的确定HARQ-ACK码本的方法200的示意性流程图,如图5所示,该方法200可以包括如下内容:
S210,终端设备接收网络设备发送的第一PDSCH,其中,该第一PDSCH是第一时间窗口内的PDSCH,该第一PDSCH对应第一HARQ-ACK信息;
S220,该终端设备确定该第一时间窗口对应的HARQ-ACK码本,该HARQ-ACK码本中包括该第一HARQ-ACK信息。
应理解,该第一时间窗口为HARQ-ACK反馈窗口。
需要说明的是,该HARQ-ACK码本为动态码本。具体可以是单载波场景下的动态码本,也可以是多载波场景下的动态码本。
可选地,在本申请实施例中,该第一PDSCH是该第一时间窗口内的第N个PDCCH检测机会指示对应的PDSCH,该第一PDSCH对应的DAI计数为M,N和M为正整数,且N<M。
换句话说,在该第一时间窗口内,该第一PDSCH是第N个PDCCH检测机会指示 对应的PDSCH,而该第一PDSCH对应的DAI计数却为M,即存在不一致的情况。
可选地,该终端设备确定该HARQ-ACK码本中的第N组HARQ-ACK信息为该第一HARQ-ACK信息,其中,每组HARQ-ACK信息包括K个HARQ-ACK比特,K为大于或等于1的正整数。
进一步地,当N为大于或等于2的正整数时,该终端设备确定该HARQ-ACK码本中的第一组至第N-1组HARQ-ACK信息为NACK信息或占位信息。
需要说明的是,占位信息不是NACK信息等具有具体含义的信息,同时占位信息所对应的位置也不能正常存放码本,例如可以理解为留空,即不用于存放码本信息。在第一组至第N-1组HARQ-ACK信息为占位信息时,该HARQ-ACK码本中,第一组至第N-1组留空,不存放信息。
可选地,该终端设备确定该HARQ-ACK码本中的第M组HARQ-ACK信息为该第一HARQ-ACK信息,其中,每组HARQ-ACK信息包括K个HARQ-ACK比特,K为大于或等于1的正整数。
进一步地,当M为大于或等于2的正整数时,该终端设备确定该HARQ-ACK码本中的第一组至第M-1组HARQ-ACK信息为NACK信息或占位信息。
可选地,在本申请实施例中,该终端设备接收该网络设备发送的第一指示信息,该第一指示信息用于确定以下信息中的至少一种:
该第一时间窗口的起始位置、该第一时间窗口的结束位置、该第一时间窗口的长度、传输该HARQ-ACK码本的资源的时域位置、传输该HARQ-ACK码本的资源的频域位置、传输该HARQ-ACK码本的资源数量。
可选地,该终端设备根据该第一指示信息确定该第一时间窗口。
可选地,该终端设备根据该第一指示信息确定传输该HARQ-ACK码本的资源的时域位置。
具体地,该终端设备根据HARQ-ACK反馈时间(timing)指示信息和该第一指示信息确定传输该HARQ-ACK码本的资源的时域位置,其中,该HARQ-ACK反馈时间指示信息为该第一时间窗口内的第一个PDSCH或最后一个PDSCH对应的HARQ-ACK反馈时间指示信息。
例如,第一PDSCH的最后一个符号的结束位置在时隙n上,HARQ-ACK反馈时间指示信息为5,第一指示信息指示的传输该HARQ-ACK码本的资源的时域位置为2,那么实际传输该HARQ-ACK码本的资源的时域位置在时隙n+7上。
可选地,作为一个实施例,对于HARQ-ACK反馈窗口内的第N个PDCCH的检测机会对应的PDSCH的DAI计数为M且N<M的情况,终端设备在进行HARQ-ACK码本确定时,该第N个PDCCH的检测机会对应的PDSCH对应的HARQ-ACK为该HARQ-ACK码本中的第M组HARQ-ACK反馈。例如,如图6所示,HARQ-ACK反馈窗口内一共包括8个时隙,每个时隙上都配置有PDCCH检测机会,HARQ-ACK反馈窗口内的第一个PDCCH的检测机会对应的PDSCH的DAI计数为2,终端设备在进行HARQ-ACK码本确定时对该HARQ-ACK反馈窗口内未发生的DAI计数为0和1对应的HARQ反馈确定为NACK。即,在这种情况下,终端设备确定HARQ-ACK码本时不受HARQ-ACK反馈窗口的限制。又例如,假设每个PDSCH对应的HARQ-ACK反馈比特的大小K=2,终端设备对图6所示的HARQ-ACK反馈窗口确定的HARQ-ACK码本如下表4所示:
表4
Figure PCTCN2018105495-appb-000004
Figure PCTCN2018105495-appb-000005
可选地,作为另一个实施例,对于HARQ-ACK反馈窗口内的第N个PDCCH的检测机会对应的PDSCH的DAI计数为M且N<M的情况,终端设备在进行HARQ-ACK码本确定时,该第N个PDCCH的检测机会对应的PDSCH对应的HARQ-ACK为该HARQ-ACK码本中的第N组HARQ-ACK反馈。例如,同样如图6所示,HARQ反馈窗口内一共包括8个时隙,每个时隙上都配置有PDCCH检测机会,HARQ-ACK反馈窗口内的第一个PDCCH的检测机会对应的PDSCH的DAI计数为3,终端设备在进行HARQ-ACK码本确定时将该DAI指示为3的PDSCH对应的HARQ反馈作为起始点。即,在这种情况下,终端设备确定HARQ-ACK码本时根据HARQ-ACK反馈窗口和DAI指示同时来确定码本。又例如,假设每个PDSCH对应的HARQ-ACK反馈比特的大小K=2,终端设备对图6所示的HARQ-ACK反馈窗口确定的HARQ-ACK码本如下表5所示:
表5
Figure PCTCN2018105495-appb-000006
需要说明的是,上述实施例仅以该HARQ-ACK码本为单载波场景下的动态码本为例进行说明,在该HARQ-ACK码本为多载波场景下的动态码本时上述实施例也适用。
因此,在本申请实施例中,当终端设备采用动态码本进行反馈时,如果HARQ-ACK反馈窗口内PDCCH检测机会指示对应的PDSCH的出现位置与PDSCH对应的DAI计数不一致时,码本确定的起始点以PDSCH出现位置为准,或者,码本确定的起始点以DAI计数为准,从而,可以使终端设备和网络设备对码本确定的认知一致。
图7是根据本申请实施例的确定HARQ-ACK码本的方法300的示意性流程图,如图7所示,该方法300可以包括如下内容:
S310,网络设备在第一时间窗口内向终端设备发送第一PDSCH,其中,该第一PDSCH对应第一HARQ-ACK信息;
S320,该网络设备确定该第一时间窗口对应的HARQ-ACK码本,该HARQ-ACK码本中包括该第一HARQ-ACK信息。
可选地,在本申请实施例中,该第一PDSCH是该第一时间窗口内的第N个PDCCH检测机会指示对应的PDSCH,该第一PDSCH对应的DAI计数为M,N和M为正整数,且N<M。
可选地,该网络设备确定该HARQ-ACK码本中的第N组HARQ-ACK信息为该第一HARQ-ACK信息,其中,每组HARQ-ACK信息包括K个HARQ-ACK比特,K为大于或等于1的正整数。
进一步地,当N为大于或等于2的正整数时,该网络设备确定该HARQ-ACK码本中的第1组至第N-1组HARQ-ACK信息为NACK信息或占位信息。
可选地,该网络设备确定该HARQ-ACK码本中的第M组HARQ-ACK信息为该第一HARQ-ACK信息,其中,每组HARQ-ACK信息包括K个HARQ-ACK比特,K为大于或等于1的正整数。
进一步地,当M为大于或等于2的正整数时,该网络设备确定该HARQ-ACK码本中的第1组至第M-1组HARQ-ACK信息为NACK信息或占位信息。
可选地,在本申请实施例中,该网络设备向该终端设备发送第一指示信息,该第一指示信息用于确定以下信息中的至少一种:
该第一时间窗口的起始位置、该第一时间窗口的结束位置、该第一时间窗口的长度、传输该HARQ-ACK码本的资源的时域位置、传输该HARQ-ACK码本的资源的频域位置、传输该HARQ-ACK码本的资源数量。
可选地,在本申请实施例中,该网络设备向该终端设备发送HARQ-ACK反馈时间指示信息,其中,该HARQ-ACK反馈时间指示信息为该第一时间窗口内的第一个PDSCH或最后一个PDSCH对应的HARQ-ACK反馈时间指示信息,该HARQ-ACK反馈时间指示信息用于确定传输该HARQ-ACK码本的资源的时域位置。
应理解,确定HARQ-ACK码本的方法300中的步骤可以参考确定HARQ-ACK码本的方法200中的相应步骤,为了简洁,在此不再赘述。
因此,在本申请实施例中,当终端设备采用动态码本进行反馈时,如果反馈窗口内PDCCH检测机会指示对应的PDSCH的出现位置与PDSCH对应的DAI计数不一致时,码本确定的起始点以PDSCH出现位置为准,或者,码本确定的起始点以DAI计数为准,从而,可以使终端设备和网络设备对码本确定的认知一致。
