Description

传输信息的方法和通信设备
本申请要求于2018年06月04日提交中国专利局、申请号为201810566032.6、申请名称为“传输信息的方法和通信设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域,尤其涉及一种传输信息的方法和通信设备。
背景技术
目前第五代移动通信技术(5-Generation,5G)相比于前几代移动通信系统在传输速率、时延及功耗等方面都提出了更高的要求。将增强型移动宽带(enhanced Mobile Broadband,eMBB),海量机器类型通信(massive machine type communication,mMTC)和超可靠低延迟通信(ultra-reliable and low-latency communication,URLLC)定义为未来5G的三大典型业务,这为5G标准的制定指明了方向。
URLLC作为5G的三大典型业务之一,主要应用场景包括:无人驾驶,远程医疗等,这些应用场景在可靠性及时延方面提出了更加严格的需求。URLLC业务具体的需求包括:数据传输可靠性达到99.999%,传输时延低于1ms,以及在满足高可靠性及低时延要求下,尽可能减小指令开销。目前针对不同的业务生成的混合自动重传请求-确认(hybrid automatic repeat request-acknowledgement,HARQ-ACK)码本是以时隙slot为单位,在同一个slot中将要反馈的确认(acknowledge,ACK)信息/非确认(negative-acknowledge,NACK)联合编码生成一个HARQ-ACK码本,从而使得在一个slot中只能在一个物理上行链路控制信道(physical uplink control channel,PUCCH)上反馈一个HARQ-ACK码本,使得本来可以在一个slot中前半部分反馈的ACK/NACK需要等到该slot的后半部分,和最后一个待反馈的ACK/NACK一起反馈,造成URLLC业务的时延增大;并且在有不同业务的PUCCH进行反馈时,为了保证高可靠性业务的反馈信息的可靠性,而分配过大的资源,造成资源浪费。
因此,如何能够保证URLLC的可靠性和时延,成为一项亟待解决的问题。

应理解,本申请实施例中的方式、情况、类别以及实施例的划分仅是为了描述的方便,不应构成特别的限定,各种方式、类别、情况以及实施例中的特征在不矛盾的情况下可以相结合。
还应理解,在本申请的各实施例中,“第一”、“第二”等仅是为了指代不同的对象,并不表示对指代的对象有其它限定。
本申请实施例的技术方案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、LTE频分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)、通用移动通信系统(universal mobile telecommunication system,UMTS)、全球互联微波接入(worldwide interoperability for microwave access,WIMAX)通信系统、未来的第五代(5th generation,5G)系统或新无线(new radio,NR)等。
本申请实施例中的终端设备可以指用户设备、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。终端设备还可以是蜂窝电话、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)、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,未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network,PLMN)中的终端设备等,本申请实施例对此并不限定。

图1是本申请实施例所用的通信系统的示意图。如图1所示,该通信系统100包括网络设备102,网络设备102可包括多个天线组。每个天线组可以包括一个或多个天线,例如,一个天线组可包括天线104和106,另一个天线组可包括天线108和110,附加组可包括天线112和114。图1中对于每个天线组示出了2个天线,然而可以对于每个组使用更多或更少的天线。网络设备102可附加地包括发射机链和接收机链,本领域普通技术人员可以理解,它们均可包括与信号发送和接收相关的多个部件,例如处理器、调制器、复用器、解调器、解复用器或天线等。
网络设备102可以与多个终端设备通信,例如,网络设备102可以与终端设备116和终端设备122通信。然而,可以理解,网络设备102可以与类似于终端设备116或122的任意数目的终端设备通信。终端设备116和122可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA和/或用于在无线通信系统100上通信的任意其它适合设备。
如图1所示,终端设备116与天线112和114通信,其中天线112和114通过前向链路118向终端设备116发送信息,并通过反向链路120从终端设备116接收信息。此外,终端设备122与天线104和106通信,其中天线104和106通过前向链路124向终端设备122发送信息,并通过反向链路126从终端设备122接收信息。
例如,在频分双工FDD系统中,例如,前向链路118可利用与反向链路120所使用的不同频带,前向链路124可利用与反向链路126所使用的不同频带。
再例如,在时分双工TDD系统和全双工(full duplex)系统中,前向链路118和反向链路120可使用共同频带,前向链路124和反向链路126可使用共同频带。
被设计用于通信的每组天线和/或区域称为网络设备102的扇区。例如,可将天线组设计为与网络设备102覆盖区域的扇区中的终端设备通信。在网络设备102通过前向链路118和124分别与终端设备116和122进行通信的过程中,网络设备102的发射天线可利 用波束成形来改善前向链路118和124的信噪比。此外,与网络设备通过单个天线向它所有的终端设备发送信号的方式相比,在网络设备102利用波束成形向相关覆盖区域中随机分散的终端设备116和122发送信号时,相邻小区中的移动设备会受到较少的干扰。
网络设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置,也可以是任意形式的通信装置。当发送数据时,无线通信发送装置可对数据进行编码以用于传输。具体地,无线通信发送装置可获取要通过信道发送至无线通信接收装置的一定数目的数据比特,例如,无线通信发送装置可生成、从其它通信装置接收、或在存储器中保存等要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块或多个传输块中,传输块可被分段以产生多个码块。
此外,该通信系统100可以是公共陆地移动网络PLMN网络或者设备对设备(device to device,D2D)网络或者机器对机器(machine to machine,M2M)网络或者其他网络,图1仅为便于理解而示例的简化示意图,网络中还可以包括其他网络设备,图1中未予以画出。
下面,对本申请实施例的传输对象(即,HARQ-ACK码本)进行详细说明。
需要说明的是,在本申请的实施例中,HARQ-ACK码本指的是将在一个时间单元内需要反馈的ACK、NACK联合编码生成的反馈信息比特。
在本申请实施例中,下行数据的传输可以采用反馈技术,作为示例而非限定,该反馈技术可以包括例如,混合自动重传请求(hybrid automatic repeat request,HARQ)技术。
其中,HARQ技术是一种将前向纠错编码(forward error correction,FEC)和自动重传请求(automatic repeat request,ARQ)相结合而形成的技术。
例如,在HARQ技术中,接收端在从发送端接收到数据后,可以确定该数据是否准确译码。如果不能准确译码,则接收端可以向发送端反馈非确认(negative-acknowledge,NACK)信息,从而,发送端可以基于NACK信息,确定接收端没有准确接收到数据,从而可以进行重传处理;如果能够准确译码,则接收端可以向发送端反馈确认(acknowledge,ACK)信息,从而,发送端可以基于ACK信息,确定接收端准确接收到数据,从而可以确定完成了数据传输。
即,在本申请实施例中,当接收端解码成功是可以向发送端ACK信息,在解码失败时可以向发送端反馈NACK信息
作为示例而非限定,在本申请实施例中,上行控制信息可以包括HARQ技术中的ACK信息或NACK信息。
在NR中,HARQ-ACK码本的确定可以按照半静态码本(semi-static codebook)模式或者按照动态码本(dynamic codebook)模式来确定。
1、动态码本,又称为类型(type)2 HARQ codebook。终端设备在每个下行控制信道(physical downlink control channel,PDCCH)检测时机(monitoring occasion)检测PDSCH,根据PDCCH中的TimeDomainResourceAllocation字节和PDSCH-to-HARQ-timing字节,确定检测到的PDCCH调度的PDSCH在哪个时隙传输,以及确定对应的ACK/NACK在哪个时隙反馈。
2、半静态码本,又称为type 1 HARQ codebook。终端设备在每个下行控制信道(physical downlink control channel,PDCCH)检测时机(monitoring occasion)检测PDSCH,根据 PDCCH中的时域分配资源(time domain resource allocation)字节和PDSCH-to-HARQ-timing字节(对应的指示值我们可以称为第一指示值K1),确定检测到的PDCCH调度的PDSCH在哪个时隙传输,以及确定对应的ACK/NACK在哪个时隙反馈。在反馈时隙中生成一个HARQ-ACK码本中不仅包括被调度的PDSCH的反馈信息,还包括按照高层信令配置的PDSCH-to-HARQ-timing集合中所有候选时隙的反馈信息,如果对应的候选时隙中没有数据发送,则在对应的反馈比特位填NACK。
图2示出了根据现有技术中动态码本模式下生成HARQ-ACK码本的示意图。如图2所示,在下行链路上包括业务1和业务2,例如业务1为eMBB的PDSCH,业务2为URLLC的PDSCH。eMBB的PDSCH在第1个slot收到,PDCCH指示第一指示值K1=2,即eMBB业务对应的PUCCH资源在第3个slot;URLLC的PDSCH在第2个slot收到,且PDCCH指示K1=1,即URLLC业务对应的PUCCH资源在第3个slot。两个业务的PDCCH指示都在第3个slot中反馈,用户在实际反馈中,会将针对eMBB业务和针对URLLC业务的ACK/NACK统一生成一个HARQ-ACK码本,然后按照第二个PDCCH即URLLC业务的PDCCH指示来确定最终的PUCCH资源,然后进行反馈。
应理解,目前生成HARQ-ACK码本是以slot为单位,在同一个slot中的要反馈的ACK/NACK生成一个HARQ-ACK码本。
在图2所示的生成HARQ-ACK码本的示意图中,由于URLLC业务可靠性要求比较高,因此会分配比较多的PUCCH资源,PUCCH资源可以包括格式、时域位置、开始位置、结束位置等信息,以便通过降低码率来保证PUCCH的可靠性。由于URLLC业务需要和eMBB业务的ACK/NACK统一反馈,所以eMBB业务也会分配更多的资源,相当于eMBB也用同样低的码率来传输,从而导致资源浪费;也就是说,如果保证了资源不浪费,那么URLLC业务的PUCCH的可靠性就无法得到保证。
图3示出了根据现有技术中动态码本模式下生成HARQ-ACK码本的示意图。如图3所示,在下行链路上包括业务1和业务2,例如业务1可以为URLLC的PDSCH,业务2可以为URLLC的PDSCH。在下行链路上包括业务1和业务2。业务1的PDSCH在第1个slot收到,PDCCH指示K1=2,即业务1对应的PUCCH资源在第3个slot;业务2的PDSCH在第2个slot收到,且PDCCH指示K1=1,即业务2对应的PUCCH资源在第3个slot。两个业务的PDCCH指示都在第3个slot中反馈。根据图3可以看出,业务1在第3个slot的反馈信息为NACK,即业务1数据传输错误,其对应的重新传可以本来可以在下行链路第3个slot中业务1的位置进行重传,但是由于两个URLLC数据对应的HARQ在同一个slot中反馈,要生成一个HARQ码本,从而导致实际的反馈信息会在业务2的ACK之后,那么实际的业务1数据的重传只能在第4个slot中业务1的位置,从而造成业务1数据的时延较大。
应理解,在下行链路中可以传输相同的业务,如图3所示;也可以传输不同的业务,如图2所示。
因此,在现有技术中HARQ-ACK码本的传输方式是以slot为单位,将在同一个slot中的要反馈的ACK/NACK只生成一个HARQ-ACK码本。一方面,使得在一个slot中只能反馈一个PUCCH,造成URLLC业务的时延增大;另一方面,在有不同业务的PUCCH进行反馈时,为了保证高可靠性业务的PUCCH而分配过大的资源,造成资源浪费。
下面将结合具体的例子详细描述本申请中传输信息的方法,其中,终端设备生成第i个时域区间对应的混合自动重传请求-确认HARQ-ACK码本,第i个时域区间的时间单元长度小于一个时隙slot。
需要说明的是,这只是为了帮助本领域技术人员更好地理解本申请实施例,而非限制本申请实施例的范围。
图4是根据本申请的一个实施例的传输信息的方法的交互性流程图。
图4中的终端设备可以为图1中任意一个终端设备,图4中的网络设备也可以为图1中的网络设备,本申请对此不作限定。
S210,终端设备生成第i个时域区间对应的混合自动重传请求-确认HARQ-ACK码本,其中,所述第i个时域区间为一个时隙的N个时域区间中的任意一个,i小于或等于N,i为正整数、N为大于1的正整数。
例如,终端设备可以以1/2时隙为单位生成一个HARQ-ACK码本,则一个时隙中可以针对前1/2时隙和后1/2时隙分别生成一个HARQ-ACK码本,即一个时隙中可以生成两个HARQ-ACK码本;终端设备还可以以1/4时隙为单位生成一个HARQ-ACK码本,则一个时隙中可以针对每个1/4分别生成一个HARQ-ACK码本,即一个时隙中可以生成4个HARQ-ACK码本。
在本申请的实施例中,网络设备确定物理上行控制信道PUCCH资源;网络设备在确定的PUCCH资源上接收终端设备发送的混合自动重传请求-确认HARQ-ACK码本,其中,该HARQ-ACK码本为第i个时域区间对应的HARQ-ACK码本,所述第i个时域区间为一个时隙的N个时域区间中的任意一个,i小于或等于N,i为正整数、N为大于1的正整数。
应理解,第i个时域区间的时间单元长度可以为一个符号、多个符号、1/2时隙、1/4时隙、1/7时隙和1/8时隙中的任意一个,本申请实施例对此不作限定。
还应理解,时间单元长度为根据标准预定义的和/或所述终端设备的高层信令预配置的。例如,标准预定义和/或高层信令预配置时间单元的长度为1/2时隙,或1/4时隙,或1/8时隙,或M个符号,M为小于14的正整数。
在本申请的实施例中,终端设备能够在一个时隙中生成至少两个码本,例如,以1/2时隙为时域区间,则在一个时隙中终端设备可以生成2个HARQ-ACK码本;或者,以1/7时隙为时域区间,则在一个时隙中终端设备可以生成7个HARQ-ACK码本。本申请实施例对此不作限定。
S220,终端设备确定所述HARQ-ACK码本对应的物理上行控制信道PUCCH资源。
在本申请的实施例中,终端设备确定PUCCH资源后向网络设备发送该PUCCH资源,即网络设备在终端设备确定的PUCCH资源上接收终端设备生成的第i个时域区间对应的HARQ-ACK码本。
S230,终端设备在所述PUCCH资源上发送所述HARQ-ACK码本。
在本申请的实施例中,网络设备接收终端设备确定的PUCCH资源,在所述PUCCH资源接收所述终端设备发送的混合自动重传请求-确认HARQ-ACK码本。
需要说明的是,HARQ-ACK码本包括动态码本模式和半静态码本模式,在终端设备生成HARQ-ACK码本之前,网络设备会可以向终端设备发送配置信息,该配置信息用于指示所述HARQ-ACK码本为动态码本模式或半静态码本模式。
可选地,终端设备生成第i个时域区间对应的HARQ-ACK码本的方式可以包括但不限于以下两种方式。
方式一:终端设备根据指示值和下行信息的时域位置信息确定第i个时域区间对应的HARQ-ACK码本。
应理解,第一指示值表示第一下行信息的时间单元到所述终端设备反馈所述第一下行信息的HARQ-ACK码本的时间单元的偏移值,或者说是第一下行信息所在的时间单元和所述第一时间单元相差的时间单元的个数。第二指示值表示第二下行信息的时间单元到所述终端设备反馈所述第二下行信息的HARQ-ACK码本的时间单元的偏移值,或者说是第二下行信息所在的时间单元和所述第一时间单元相差的时间单元的个数。其中,第一下行信息所在的时间单元指第一下行信息所占的时域位置的最后一个符号所在的时间单元,或者第一下行信息所占的时域位置的第一个符号所在的时间单元。其中,第二下行信息所在的时间单元是指第二下行信息所占的时域位置的最后一个符号所在的时间单元,或者第二下行信息所占的时域位置的第一个符号所在的时间单元。
第一种可能的实现方式中,终端设备生成第i个时域区间对应的HARQ-ACK码本,该HARQ-ACK码本的模式为动态码本模式下生成的码本。即,基于网络设备实时调度的PDSCH个数来终端设备确定码本中包括的反馈信息。
例如,网络设备配置该终端设备生成的HARQ-ACK码本模式为动态码本模式。
作为一个可选的实施例,终端设备首先可以确定第一指示值,接收第一下行信息,终端设备可以根据第一下行信息的时域位置信息和第一指示值确定第一下行信息对应的反馈信息所在的第一时间单元,终端设备判断所述第一时间单元属于所述第i个时域区间,则所述终端设备生成所述第i个时域区间对应的HARQ-ACK码本包括所述第一时间单元中对应的反馈信息。
例如,在图5中示出了根据本申请一个实施例中的生成HARQ-ACK码本的示意图。如图5所示,假设终端设备根据接收到的第一下行信息中指示第一指示值为1,根据协议或者高层配置信息指示第一指示值的时间单元长度为1/2时隙,终端设备在第n个1/2时隙接收的第一下行信息,第一下行信息对应的反馈信息在第(n+1)个1/2时隙,即第一时间单元为第(n+1)个1/2时隙。
若第i个时域区间包括一个第一时间单元,则终端设备生成第i个时域区间的HARQ-ACK码本即为第一时间单元对应的反馈信息。若第i个时域区间包括多个第一时间单元,例如,第i个时域区间为第n个1/2时隙到第(n+1)个1/2时隙,则终端设备生成第i个时域区间的HARQ-ACK码本包括第一时间单元对应的反馈信息,即第(n+1)个1/2时隙对应的反馈信息,终端设备生成第i个时域区间的HARQ-ACK码本为第n个1/2时隙对应的反馈信息和第(n+1)个1/2时隙对应的反馈信息的联合编码后生成的码本。
在本申请的实施例中,第一指示值可以是根据标准预定义的和/或高层信令预配置的一个值。第一指示值还可以是终端设备接收网络设备发送的第一下行控制信息,第一下行控制信息中包括第一指示值。
例如,第一指示值可以是根据标准预定义的一个集合,根据第一下行控制信息的指示,从集合中确定一个第一指示值。
例如,第一指示值可以是根据高层信令预配置的一个集合,根据第一下行控制信息的 指示,从集合中确定一个第一指示值。
在本申请的实施例中,网络设备向终端设备发送第一下行信息,网络设备可以发送一个或者多个下行信息,所述网络设备在所述PUCCH资源上接收所述终端设备发送的混合自动重传请求-确认HARQ-ACK码本,包括:

应理解,在本申请的实施例中,第一指示值具有时间单元长度,第一指示值的时间单元长度可以为一个符号、多个符号、1/2时隙、1/4时隙、1/8时隙或1/7时隙中的任意一个。该时间单元的长度还可以是根据标准预定义的和/或所述终端设备的高层信令预配置的,本申请对此不作限定。在本申请的实施例中,第一指示值的时间单元长度小于或者等于第i个时域区间的时间单元长度。

第二种可能的实现方式中,终端设备生成第i个时域区间对应的HARQ-ACK码本,该HARQ-ACK码本为半静态码本模式下生成的码本。
例如,网络设备配置该终端设备生成的HARQ-ACK码本为半静态码本模式。
作为一个可选的实施例,终端设备首先确定第二指示值的集合,所述第二指示值表示所述第二下行信息所在的时间单元和所述第二下行信息对应的反馈信息所在的时间单元相差的时间单元的个数;终端设备根据所述第i个时域区间和所述第二指示值的集合确定第二下行信息的时域位置信息集合;所述终端设备在所述第i个时域区间根据所述第二下行信息所在的时间单元集合对应的下行信息的反馈信息生成所述HARQ-ACK码本。
应理解,在本申请的实施例中,终端设备可以接收至少一个第二下行信息。
例如,在图6中示出了根据本申请一个实施例中的生成HARQ-ACK码本的示意图。如图6所示,终端设备根据第i个时域区间和第二指示值的集合确定第二下行信息的时域位置信息集合,假设第i个时域区间为第n个1/2时隙,第二指示值的集合包括{0,1,2,3,4},第二指示值的时间单元可以为1/2slot,则终端设备可以确定在第i个时域区间可以发送第第n个1/2时隙,第n-1个1/2时隙,第n-2个1/2时隙,第n-3个1/2时隙,第n-4个1/2时隙的内的所有的第二下行信息对应的反馈信息,其中,第n个1/2时隙,第n-1个1/2时隙,第n-2个1/2时隙,第n-3个1/2时隙即为第二下行信息所在的时域单元集合。如果终端设备在该时域单元集合中至少收到了一个第二下行信息,则终端设备在第n个1/2slot中的反馈信息包括第n个1/2时隙,第n-1个1/2时隙,第n-2个1/2时隙,第n-3个1/2时隙,第n-4个1/2时隙的下行信息集合对应的ACK/NACK比特,这些比特联合编码生成一个HARQ-ACK码本,即终端设备在所述第i个时域区间根据第二下行信息所在的时间单元集合对应的下行信息的反馈信息生成所述HARQ-ACK码本。
需要说明的是,在本申请的实施例中,第二指示值的时间单元可以小于或者等于第i个时域区间的时域长度。
在本申请的实施例中,第二指示值的集合可以为根据协议标准预定义的,或者,第二指示值的集合可以为高层信令配置的。
其中,高层信令可以为MAC信令,或者为可以是指高层协议层发出的信令,高层协议层为物理层以上的至少一个协议层。其中,高层协议层具体可以包括以下协议层中的至少一个:媒体接入控制(medium access control,MAC)层、无线链路控制(radio link control,RLC)层、分组数据会聚协议(packet data convergence protocol,PDCP)层、无线资源控制(radio resource control,RRC)层和非接入层(non access stratum,NAS)。
在本申请的实施例中,时间单元的长度还可以是根据标准预定义的和/或所述终端设备的高层信令预配置的,本申请对此不作限定。
例如,时间单元长度可以为一个符号、多个符号(小于14个符号)、1/2时隙、1/4时隙、1/7时隙和1/8时隙中的任意一个,本申请对此不作限定。在本申请的实施例中。
在本申请的实施例中通过将第一指示值的时间单元长度变成1/2slot,或者1/4slot,或者1/7slot,或者1/8slot,或者一个或者多个符号(具体的值可以是协议规定的或者高层信令配置的),能够使得用户快速反馈PDSCH对应的ACK/NACK,从而实现快速反馈,降低反馈时延。
在本申请的实施例中,第i个时域区间的时域长度可以为根据标准预定义的或所述网络设备的高层信令预配置的,本申请对此不作限定。
例如,第i个时域区间的时域长度可以为Q个符号、1/2时隙、1/4时隙、1/7时隙或1/8时隙中的任意一个,其中,Q为小于14的正整数。
在本申请的实施例中,终端设备针对每个时域区间分别生成一个HARQA-ACK码本,由于时域区间的长度小于一个slot,例如,可以通过协议规定或者高层信令配置,可以为1/2slot,1/4slot,1/7时隙,1/8slot,或者一个或者多个符号,从而实现一个slot内生成至少两个HARQ码本,从而实现反馈至少两个PUCCH,能够保证低时延业务的PUCCH能够快速反馈,能够保证时延;并且在有不同业务的PUCCH进行反馈时,不需要合并进行反馈,避免为了保证某些的PUCCH的可靠性,而造成资源浪费。
方式二:终端设备根据下行信息的时域位置信息和PUCCH资源指示值确定第i个时域区间对应的HARQ-ACK码本。
应理解,在本申请的实施例中,终端设备可以根据K1指示值、下行信息的时域位置信息和PUCCH资源指示值确定第i个时域区间对应的HARQ-ACK码本。
例如,通过将一个时隙划分为多个时域区间,将确定的PUCCH资源处于每个时域区间的分别生成一个HARQ-ACK码本,由于时域区间的长度小于一个时隙,从而实现在一个时隙内生成多个HARQ-ACK码本,从而实现一个时隙内反馈至少两个PUCCH。
第一种可能的实现方式中,终端设备生成第i个时域区间对应的HARQ-ACK码本,该HARQ-ACK码本为动态码本模式下生成的码本。
例如,网络设备配置该终端设备生成的HARQ-ACK码本为动态码本模式。
作为一个可选的实施例,终端设备首先可以确定第一指示值,接收第一下行信息,终端设备可以根据第一下行信息的时域位置信息、第一指示值和第一PUCCH资源指示值确定第一PUCCH资源的时域位置,终端设备判断所述第一PUCCH资源的时域位置属于所述第i个时域区间,则所述终端设备生成所述第i个时域区间对应的HARQ-ACK码本包括所述第一PUCCH资源的时域位置对应的下行信息的反馈信息。
其中,第一指示值表示第一下行信息的时间单元到所述终端设备反馈所述第一下行信息的HARQ-ACK码本的时间单元的偏移值或者说是第一下行信息所在的时间单元和所述第一时间单元相差的时间单元的个数。其中第一下行信息所在的时间单元指第一下行信息所占的时域位置的最后一个符号所在的时间单元,或者第一下行信息所占的时域位置的第一个符号所在的时间单元。
第一PUCCH资源指示值可以用于指示所述第一PUCCH的开始符号和长度信息,即该第一PUCCH资源指示值用于指示第一PUCCH的时域位置。该第一PUCCH资源指示值可以直接指示第一PUCCH的时域位置,也可以指示一个索引,该索引指向一个PUCCH资源集合中的一个PUCCH,该PUCCH的时域位置即为第一PUCCH的时域位置。如果终端设备了多个PUCCH资源集合,则终端设备首先要根据反馈信息的比特数确定其中一个PUCCH资源集合,然后再通过PUCCH资源指示值指示的index确定该PUCCH集合内具体的PUCCH,该PUCCH的时域位置即为第一PUCCH的时域位置;如果终端设备只被配置了一个PUCCH资源,则该PUCCH资源的指示值指示的index可以直接确定第一PUCCH的时域位置。在本申请的实施例中,第一PUCCH资源指示值可以承载在第一下 行控制信息中。
例如,假设第一PUCCH资源指示值直接指示第一PUCCH的时域位置。终端设备在第n个slot接收到第一下行信息,第一指示值为1个slot,且第一PUCCH资源指示值指示开始符号为第2个符号,长度为2,则在该第一下行信息对应的PUCCH的时域资源在第n+1个slot的第2到第4个符号。
若第n+1个slot的第2到第4个符号属于第i个时域区间,则所述终端设备生成所述第i个时域区间对应的HARQ-ACK码本包括所述第一PUCCH资源的时域位置对应的下行信息的反馈信息。
再例如,假设第一PUCCH资源指示值通过指示index来指示指示第一PUCCH的时域位置。终端设备在第n个slot接收到第一下行信息,第一指示值为1个slot,且第一PUCCH资源指示值指示一个index,该index可以指示一个PUCCH资源集合中的一个PUCCH,根据该index确定第一PUCCH的开始符号为第2个符号,长度为2,则在该第一下行信息对应的PUCCH的时域资源在第n+1个slot的第2到第4个符号。
若第n+1个slot的第2到第4个符号属于第i个时域区间,则所述终端设备生成所述第i个时域区间对应的HARQ-ACK码本包括所述第一PUCCH资源的时域位置对应的下行信息的反馈信息。
若第i个时域区间包括一个第一PUCCH资源的时域位置,则终端设备生成第i个时域区间的HARQ-ACK码本即为第一PUCCH资源的时域位置对应的下行信息的反馈信息。若有多个第一PUCCH资源的时域位置在第i个时域区间内,例如,第i个时域区间为第n个1/2时隙到第(n+1)个1/2时隙,则终端设备生成第i个时域区间的HARQ-ACK码本包括第一PUCCH资源的时域位置对应的下行信息的反馈信息,即第(n+1)个1/2时隙对应的反馈信息,终端设备生成第i个时域区间的HARQ-ACK码本为第n个1/2时隙对应的反馈信息和第(n+1)个1/2时隙对应的反馈信息的联合编码后生成的码本。
需要说明的是,第一PUCCH的时域位置属于所述第i个时域区间,以第i个时域区间为1/2时隙为例说明。例如,第一PUCCH的时域位置的开始位置和时域结束位置均在1/2时隙的时域资源内,或者,第一PUCCH的时域位置的开始位置在1/2时隙的时域资源内,结束位置不在该1/2时隙的时域资源内;或者,第一PUCCH的时域位置的开始位置不在1/2时隙的时域资源内,结束位置在该1/2时隙的时域资源内。具体是上述哪一种方式为协议预定义的,即协议选择上述一种方式来确定第一PUCCH的时域位置属于所述第i个时域区间。
在本申请的实施例中,第一指示值可以是根据标准预定义的和/或高层信令预配置的一个值。第一指示值还可以是终端设备接收网络设备发送的第一下行控制信息,第一下行控制信息中包括第一指示值。
例如,第一指示值可以是根据标准预定义的一个集合,根据第一下行控制信息的指示,从集合中确定一个第一指示值。
例如,第一指示值可以是根据高层信令预配置的一个集合,根据第一下行控制信息的指示,从集合中确定一个第一指示值。
