Description

码本确定方法、通信设备及存储介质 技术领域
本申请涉及通信技术领域,尤其涉及一种码本确定方法、通信设备及存储介质。
背景技术
物理侧链路反馈信道(Physical Sidelink Feedback Channel,,PSFCH)用于携带从物理侧链路数据信道(Physical Sidelink Share Channel,PSSCH)收到的侧链传输的自动重传请求(Hybrid Acknowledgment Request,HARQ)反馈。PSFCH的结构与物理上行链路控制信道(Physical Uplink Control Channel,PUCCH)格式0相似,即ACK或NACK是通过旋转长度为12的频域基本序列的不同相位来表示。然后,相位旋转序列被映射到一个分配给PSFCH传输的资源块。PSFCH资源可以被配置为出现在资源池的每一个时隙、每两个时隙和每四个时隙。
由于PSFCH资源可以被配置为出现在资源池的每一个时隙、每两个时隙和每四个时隙,说明如果interlace传输用于PSFCH,一个资源池在每个时隙中最多有10个PSFCH资源。考虑到PSFCH上只携带一个比特的侧链路HARQ反馈,如此稀缺的PSFCH资源不足以携带针对PSSCH传输的HARQ反馈,进而可能导致不能及时传输HARQ反馈。
因此,有必要提出一种提高PSFCH资源上HARQ承载力的解决方案。
前面的叙述在于提供一般的背景信息,并不一定构成现有技术。

本申请的实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
需要说明的是,在本文中,术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含,从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素,而且还包括没有明确列出的其他要素,或者是还包括 为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下,由语句“包括一个……”限定的要素,并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素,此外,本申请不同实施例中具有同样命名的部件、特征、要素可能具有相同含义,也可能具有不同含义,其具体含义需以其在该具体实施例中的解释或者进一步结合该具体实施例中上下文进行确定。
应当理解,尽管在本文可能采用术语第一、第二、第三等来描述各种信息,但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如,在不脱离本文范围的情况下,第一信息也可以被称为第二信息,类似地,第二信息也可以被称为第一信息。取决于语境,如在此所使用的词语"如果"可以被解释成为"在……时"或"当……时"或"响应于确定"。再者,如同在本文中所使用的,单数形式“一”、“一个”和“该”旨在也包括复数形式,除非上下文中有相反的指示。应当进一步理解,术语“包含”、“包括”表明存在所述的特征、步骤、操作、元件、组件、项目、种类、和/或组,但不排除一个或多个其他特征、步骤、操作、元件、组件、项目、种类、和/或组的存在、出现或添加。本申请使用的术语“或”、“和/或”、“包括以下至少一个”等可被解释为包括性的,或意味着任一个或任何组合。例如,“包括以下至少一个:A、B、C”意味着“以下任一个:A;B;C;A和B;A和C;B和C;A和B和C”,再如,“A、B或C”或者“A、B和/或C”意味着“以下任一个:A;B;C;A和B;A和C;B和C;A和B和C”。仅当元件、功能、步骤或操作的组合在某些方式下内在地互相排斥时,才会出现该定义的例外。
应该理解的是,虽然本申请实施例中的流程图中的各个步骤按照箭头的指示依次显示,但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明,这些步骤的执行并没有严格的顺序限制,其可以以其他的顺序执行。而且,图中的至少一部分步骤可以包括多个子步骤或者多个阶段,这些子步骤或者阶段并不必然是在同一时刻执行完成,而是可以在不同的时刻执行,其执行顺序也不必然是依次进行,而是可以与其他步骤或者其他步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
取决于语境,如在此所使用的词语“如果”、“若”可以被解释成为“在……时”或“当……时”或“响应于确定”或“响应于检测”。类似地,取决于语境,短语“如果确定”或“如果检测(陈述的条件或事件)”可以被解释成为“当确定时”或“响应于确定”或“当检测(陈述的条件或事件)时”或“响应于检测(陈述的条件或事件)”。
需要说明的是,在本文中,采用了诸如S1、S2等步骤代号,其目的是为了更清楚简要地表述相应内容,不构成顺序上的实质性限制,本领域技术人员在具体实施时,可能会先执行S2后执行S1等,但这些均应在本申请的保护范围之内。
应当理解,此处所描述的具体实施例仅仅用以解释本申请,并不用于限定本申请。
在后续的描述中,使用用于表示元件的诸如“模块”、“部件”或者“单元”的后缀仅为了有利于本申请的说明,其本身没有特定的意义。因此,“模块”、“部件”或者“单元”可以混合地使用。

第六实施例
在本申请上述实施例的基础上,本实施例进一步公开了前述实施例中的码本确定方法。
在本申请实施例中,终端在一个HARQ反馈资源(PSFCH信道)上反馈HARQ-ACK信息的整体称为HARQ-ACK码本。终端至少针对以下几种侧链路传输数据进行HARQ-ACK反馈。
(1)表示有对应PSCCH调度的PSSCH数据传输。
(2)表示无对应PSCCH调度的SL configured grant的PSSCH数据传输。
可选地,所述码本指的是HARQ-ACK码本大小不随实际的数据调度情况动态改变的一种HARQ-ACK码本生成方式。在此方式下,HARQ-ACK的码本大小根据预定义或RRC配置的参数来确定。
可选地,对于半静态码本在PSFCH上的反馈,HARQ-ACK码本的生成分为以下两个步骤。
步骤1:针对特定HARQ-ACK反馈时间单元,即第一类型时隙n,对应的每个服务小区中激活的侧链路BWP,所有需要HARQ-ACK反馈的侧链路数据传输的集合(包括上述两类PSSCH,可统称为候选PSSCH接收时机)。该候选PSSCH接收时机集合记为MA,c。其中MA,c是根据下列参数来确定的。所述第一类型时隙为逻辑时隙,即包含在资源池内的时隙。
该激活侧链路BWP关联的资源池内的PSFCH信道周期。
参照图9,图9为根据第六实施例示出的码本确定方法的第一示例原理示意图,如图9所示,假设PSFCH周期为4个时隙,则PSFCH所在第一类型时隙为n,n+4,.......,n+4i。
假设PSSCH与PSFCH之间的最小间隔为2个时隙,则对应于在第一类型时隙n的PSFCH传输时机,其对应的PSSCH传输为第一类型时隙n-2,第一类型时隙n-3,第一类型时隙n-4,第一类型时隙n-5。(第一类型时隙n-6对应的PSSCH对应第一类型时隙(n-4)-2,即第一类型时隙(n-4)的PSFCH传输时机),此时,MA,c={2,3,4,5}。
参照图10,图10为根据第六实施例示出的码本确定方法的第二示例原理示意图,如图10所示,如果承载HARQ码本的PSFCH在候选的第一个PSFCH传输时机上因为LBT失败没有发送,则未发送的HARQ-ACK继续累积。如 果承载HARQ码本的PSFCH在前N-1个PSFCH传输时机上均未能发送,则在第N个PSFCH传输时机上,对应于第一类型时隙n的第N个PSFCH传输时机,其对应的PSSCH传输为第一类型时隙n-2,第一类型时隙n-3,第一类型时隙n-4,第一类型时隙n-5,......,第一类型时隙n-4*(N-1)-5。此时,MA,c={2,3,4,5,......,4*N+1}。考虑到码本的不宜太大,所述N的取值可以通过RRC配置确定。
步骤2:根据步骤1获得的各小区候选PSSCH接收时机集合和RRC配置的小区个数,HARQ空间绑定参数、CBG配置参数和各小区支持的最大码字(Codeword)参数至少之一,确定HARQ-ACK码本。
每个小区依次按照候选PSSCH接收时机集合MA,c中的每个候选PSSCH接收时机生成相应的HARQ-ACK信息比特。候选PSSCH接收时机集合MA,c中包括J个元素,其中,J为大于或等于1的正整数,c为小区的标识。
可选地,如果PSSCH信道支持最大两层传输,则将第一个候选PSSCH接收时机上可能承载的第一个传输块(Transport Block,TB)对应的第一HARQ-ACK信息置于码本的第一个位置;将第一个候选PSSCH接收时机上可能承载的第二个传输块对应的第二HARQ-ACK信息置于码本的第二个位置。以此类推,直到将最后一个候选PSSCH接收时机上可能承载的第二个传输块对应的第2*J个HARQ-ACK信息置于码本的第2*J个位置。
可选地,如果PSSCH信道支持最大两层传输,且支持HARQ-ACK信息空分复用,则第一个候选PSSCH接收时机上可能承载的第一个传输块对应的第一HARQ-ACK信息和第二个传输块对应的第二HARQ-ACK信息做与操作(即第一HARQ-ACK信息和第二第二HARQ-ACK信息逻辑上相乘),并将结果置于码本的第1个位置。以此类推,直到将最后一个候选PSSCH接收时机上可能承载的第一个传输块对应的第一HARQ-ACK信息和第二个传输块对应的第二HARQ-ACK信息做与操作,并将结果置于码本的第J个位置。
可选地,如果PSSCH信道支持CBG(Code Block Group,码块组)传输,并且其一个传输块的最大码块数目为M,则将第一个候选PSSCH接收时机上可能承载的第一个传输块(Transport Block,TB)的第一个码块组对应的第一HARQ-ACK信息置于码本的第一个位置;将第一个候选PSSCH接收时机上可能承载的第一个传输块的第二个码块组对应的第二HARQ-ACK信息置于码本的第二个位置;......,将第一个候选PSSCH接收时机上可能承载的第一个传输块的第M个码块组对应的第M个HARQ-ACK信息置于码本的第M个位置,以此类推,直到将最后一个候选PSSCH接收时机上可能承载的第一个传输块的第M个码块组对应的第M*J个HARQ-ACK信息置于码本的第M*J个位置。
本实施例通过上述方案,具体包括根据物理侧链路反馈信道的周期内的一个或多个物理侧链路数据信道接收时机,选取或确定所述候选物理侧链路数据信道接收时机集合,并在未能在当前所述物理侧链路反馈信道周期内的所述候选物理侧链路反馈信道上发送HARQ码本的情况下,将未发送的HARQ-ACK继续累积,确保HARQ反馈能够及时传输。
第七实施例
在本申请上述实施例的基础上,本实施例进一步公开了前述实施例中的码本确定方法。
在本申请实施例中,终端在一个HARQ反馈资源(PSFCH信道)上反馈HARQ-ACK信息的整体称为HARQ-ACK码本。终端至少针对以下几种侧链路传输数据进行HARQ-ACK反馈。
(1)表示有对应PSCCH调度的PSSCH数据传输。
(2)表示无对应PSCCH调度的SL configured grant的PSSCH数据传输。
可选地,所述码本指的是HARQ-ACK码本大小不随实际的数据调度情况动态改变的一种HARQ-ACK码本生成方式。在此方式下,HARQ-ACK的码本大小根据预定义或RRC配置的参数来确定。
可选地,对于半静态码本在PSFCH上的反馈,HARQ-ACK码本的生成分为以下两个步骤。
步骤1:针对特定HARQ-ACK反馈时间单元,即第一类型时隙n,对应的每个服务小区中激活的侧链路BWP,所有需要HARQ-ACK反馈的侧链路数据传输的集合(包括上述两类PSSCH,可统称为候选PSSCH接收时机)。该候选PSSCH接收时机集合记为MA,c。其中MA,c是根据下列参数来确定的。所述第一类型时隙为逻辑时隙,即包含在资源池内的时隙。
该激活侧链路BWP关联的资源池内的PSFCH信道周期。
假设PSFCH周期为4个时隙,则PSFCH所在第一类型时隙为n,n+4,.......,n+4i。
可选地,PSFCH信道与PUCCH信道之间关联的K集合中,所述K集合来自于DCI(Downlink Control Information,下行链路控制信息):sl-PSFCH-ToPUCCH或者高层参数者sl-PSFCH-ToPUCCH-CG-Type1。
可选地,假设PUCCH传输的第二类型时隙为j1,j2,j3,......,等,其关联的PSFCH传输时机为第一类型时隙n,n+4,.......,n+4i;其中第二类型时隙为小区内的实际时隙需满足:n+k1+delta1=j1;n+4+k2+delta2=j1等。
可选地,假设PSSCH与PSFCH之间的最小间隔为2个时隙,则对应于在第一类型时隙n的PSFCH传输时机,其对应的PSSCH传输为第一类型时隙n-2,第一类型时隙n-3,第一类型时隙n-4,第一类型时隙n-5。(第一类型时隙n-6对应的PSSCH对应第一类型时隙(n-4)-2,即第一类型时隙(n-4)的PSFCH传输时机)。如果第一类型时隙n的PSFCH传输时机加上DCI中指示的K1值再加上delta1等于第二类型时隙j1,即终端需要在第二类型 时隙j1的PUCCH资源上反馈在第一类型时隙n接收到的承载与PSFCH信道的侧链路反馈信息。以此类推,终端需要在第二类型时隙j1的PUCCH资源上反馈在第一类型时隙n+4接收到的承载与PSFCH信道的侧链路反馈信息。此时,满足n+k1+delta1=j1;n+4+k2+delta2=j1;则此时,MA,c={2,3,4,5}。其中delta1,delta2为第一类型时隙和第二类型时隙转化时所需的参数。
参照图11,图11为根据第七实施例示出的码本确定方法的第一示例原理示意图,如图11所示,如果承载HARQ码本的PSFCH在候选的第一个PSFCH传输时机上因为LBT失败没有发送,则未发送的HARQ-ACK继续累积。如果承载HARQ码本的PSFCH在第N-1个PSFCH传输时机上均未能发送,则在第N个PSFCH传输时机上,对应于第一类型时隙n的第N个PSFCH传输时机,其对应的PSSCH传输为第一类型时隙n-2,第一类型时隙n-3,第一类型时隙n-4,第一类型时隙n-5,......,第一类型时隙n-4*(N-1)-5。如果第一类型时隙n的PSFCH传输时机加上DCI中指示的K1值再加上delta1等于第二类型时隙j1,即终端需要在第二类型时隙j1的PUCCH资源上反馈在第一类型时隙n接收到的承载与PSFCH信道的侧链路反馈信息。以此类推,终端需要在第二类型时隙j1的PUCCH资源上反馈在第一类型时隙n-4*(N-1)-5接收到的承载与PSFCH信道的侧链路反馈信息。此时,满足n+k1+delta1=j1;n-4*(N-1)-5+kn+deltan=j1;此时,MA,c={2,3,4,5,......,4*N+1}。其中delta1,deltan为第一类型时隙和第二类型时隙转化时所需的参数。
同上,承载HARQ码本的PSFCH在第N个PSFCH传输时机,此时该PSFCH传输时机对应第一类型时隙n。如果此时不能满足第一类型时隙n的PSFCH传输时机加上DCI中指示的K1值再加上delta1等于第二类型时隙j1。此时HARQ码本重置,即MA,c={}。发送终端放弃传输承载HARQ码本的PSFCH信道。
步骤2:根据步骤1获得的各小区候选PSSCH接收时机集合和RRC配置的小区个数,HARQ空间绑定参数、CBG配置参数和各小区支持的最大码字(Codeword)参数至少之一,确定HARQ-ACK码本。
每个小区依次按照候选PSSCH结束时机集合MA,c中的每个候选PSSCH接收时机生成相应的HARQ-ACK信息比特。候选PSSCH结束时机集合MA,c中包括J个元素,其中,J为大于或等于1的正整数,c为小区的标识。具体过程可参见上述第五实施例,此处不再赘述。
本实施例通过上述方案,具体包括根据物理侧链路反馈信道的周期内的一个或多个物理侧链路数据信道接收时机,选取或确定所述候选物理侧链路数据信道接收时机集合,并在未能在当前所述物理侧链路反馈信道周期内的所述候选物理侧链路反馈信道上发送HARQ码本的情况下,将未发送的HARQ-ACK继续累积,确保HARQ反馈能够及时传输。

可选地,所述PSSCH接收时机在任意一个COT内。参照图12,图12为根据第八实施例示出的码本确定方法的第一示例原理示意图,如图12所示,假设PSSCH与PSFCH之间的最小间隔为2个时隙,则对应于在第一类型时隙n的PSFCH传输时机,其对应的PSSCH传输为第一类型时隙n-2,第一类型时隙n-3,第一类型时隙n-4,第一类型时隙n-5。(第一类型时隙n-6对应的PSSCH对应第一类型时隙(n-4)-2,即第一类型时隙(n-4)的PSFCH传输时机)。
可选地,如果所述PSSCH传输时机均在同一COT内,此时,MA,c={2,3,4,5}。
