本申请主张在2019年7月24日在中国提交的中国专利申请号No.201910673336.7的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,尤其涉及一种旁链路信息传输方法、终端和控制节点。
背景技术
在新空口(New Radio,NR)系统中,对于下行数据包的传输,终端可以根据自己的接收和解码状况,在物理上行链路控制信道(Physical Uplink Control Channel,PUCCH)或者物理上行共享信道((Physical Uplink Shared Channel,PUSCH)上反馈混合自动重传请求应答(Hybrid Automatic Repeat reQuest-Acknowledgement,HARQ-ACK)信息(即非确认字符NACK或者确认字符ACK)来告知控制节点该下行数据包的传输是否成功,从而帮助控制节点决定是否需要重传。
在旁链路(sidelink)上,终端通过物理旁链路控制信道(Physical Sidelink Control Channel,PSCCH)发送旁链路控制信息(Sidelink Control Information,SCI),调度物理旁链路共享信道(Physical Sidelink Shared Channel,PSSCH)的传输以发送sidelink数据。为了提高sidelink上数据传输的可靠度和资源利用率,在NR sidelink技术中也引入了HARQ反馈机制:sidelink接收终端收到sidelink数据后可以反馈sidelink HARQ-ACK信息来指示sidelink的传输是成功还是失败,该HARQ应答通过物理旁链路反馈信道(Physical Sidelink Feedback Channel,PSFCH)发送。
但是和NR Uu口下行数据包的HARQ反馈机制不同的是,sidelink传输可能并不是在控制节点和终端之间进行的,而是在终端和终端之间的sidelink上进行的,因此控制节点无法直接知道该sidelink数据包的传输是否成功,需 要由终端将Sidelink HARQ-ACK信息发送给控制节点,从而控制节点才可以进一步确定sidelink上的传输是否成功,并最终确定接下来是否需要调度发送终端在sidelink上进行重传。
目前sidelink终端如何将sidelink信息发出去的具体步骤和细节都还没有讨论。

具体实施方式
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
本申请的说明书和权利要求书中的术语“包括”以及它的任何变形,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。此外,说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一,例如A和/或B,表示包含单独A,单独B,以及A和B都存在三种情况。
在本公开实施例中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更可选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
下面结合附图介绍本公开的实施例。本公开实施例提供的一种旁链路信息的传输方法、终端和控制节点可以应用于无线通信系统中。该无线通信系统可以为采用5G系统,或者演进型长期演进(Evolved Long Term Evolution,eLTE)系统,或者后续演进通信系统。
请参见图1a和图1b,图1a和图1b是本公开实施例可应用的网络系统的结构图,如图1所示,包括第一终端11、第二终端12和控制节点13,其中,第一终端11和第二终端12可以是用户终端或者其他终端侧设备,例如: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)或可穿戴式设备(Wearable Device)等终端侧设备,需要说明的是,在本公开实施例中并不限定第一终端11和第二终端12的具体类型。上述控制节点13可以为网络设备,也可以中终端。该网络设备可以是5G基站,或者以后版本的基站,或者其他通信系统中的基站,或者称之为节点B,演进节点B,或者发送接收点(Transmission Reception Point,TRP),或者接 入点(Access Point,AP),或者所述领域中其他词汇,只要达到相同的技术效果,所述网络设备不限于特定技术词汇。另外,上述网络设备可以是主节点(Master Node,MN),或者辅节点(Secondary Node,SN)。需要说明的是,在本公开实施例中仅以5G基站为例,但是并不限定网络设备的具体类型。
请参见图2,图2是本公开实施例提供的一种旁链路信息的传输方法的流程图,该方法应用于终端,如图2所示,包括以下步骤:
步骤201,根据目标资源配置确定目标资源;
步骤202,在所述目标资源上发送目标旁链路信息,所述目标旁链路信息为第一配置旁链路授权对应的第一旁链路信息,或者所述目标旁链路信息为所述第一旁链路信息与第一信息的复用信息,所述第一信息为除所述第一配置旁链路授权之外的其他调度对应的旁链路信息。
在本公开实施例中,上述终端为旁链路传输系统中除控制节点以外的终端,例如,可以为发送旁路传输的发送终端,也可以为接收旁链路传输的接收终端,还可以为中间终端,该中间终端为所述发送终端或者所述接收终端传输数据到控制节点的中间传输节点,该中间传输节点不包括发送终端。以下各实施例中,以终端为旁路传输的发送终端和旁路传输的接收终端为例进行说明。此时,上述目标通知消息的接收方可以为控制节点,也可以为上述中间终端,以下各实施例中,以目标通知信息的接收方为控制节点为例进行说明。
可选的,上述终端为发送终端时,发送终端可以通过PSFCH或PSSCH接收旁链路信息。上述终端为接收终端时,可以根据旁链路传输的接收状态确定旁链路信息。为了方便理解,以下对发送终端接收旁链路信息以及接收终端确定旁链路信息统称为终端获取旁链路信息。
上述目标资源配置可以是控制节点配置(或指示)的、协议定义的、预配置的、终端间协商的或者其他终端指示的,在此不做进一步的限定,目标资源配置可以配置多个传输资源,该目标资源配置中配置的至少一个传输资源。
本实施例中,在终端获取旁链路信息后,可以将该旁链路信息映射为目标通知信息,并利用目标资源将该目标通知信息发送至控制节点。该旁链路信息包含对应一个或者多个sidelink传输的sidelink HARQ-ACK信息,旁链 路调度请求(Scheduling request,SR)和信道状态信息(Channel State Information,CSI)等中的至少一项。上述控制节点可以支持sidelink链路和/或Uu链路,其中,终端将sidelink信息映射为目标通知信息,若通过sidelink链路发送至控制节点时,该控制节点可以称之为sidelink控制节点;若通过Uu链路发送至控制节点时,该控制节点可以称之为Uu控制节点。当控制节点为Uu控制节点时,上述目标资源可以为PUCCH或PUSCH。当控制节点为sidelink控制节点,目标资源可以为PSFCH或PSSCH。
需要说明的是,上述第一信息可以包括以下至少一项:至少一个第二配置旁链路授权对应的第二旁链路信息;动态调度对应的第三旁链路信息。其中,动态调度通常是指通过调度信令动态分配资源,即每个动态调度的传输有一个对应的调度信令,在本专利中调度sidelink传输的调度信令可以是DCI也可能是SCI,例如当控制节点在sidelink上工作时,可以通过SCI调度终端进行sidelink传输。sidelink传输包含了控制部分和数据部分中的至少一项。第三旁链路信息指通过动态调度进行旁链路传输所对应的旁链路信息。在本公开实施例中,对于第一旁链路信息可以有不同的理解:
在一可选实施例中,上述第一配置旁链路授权可以理解为所有的配置旁链路授权,此时其他调度具体指动态调度。
在另一可选实施例中,上述第一配置旁链路授权可以理解为对于所有的type1(即configured sidelink grant type1)对应的旁链路授权(configured sidelink grant)称为第一配置旁链路授权,其他调度包括动态调度和type2(即configured sidelink grant type2)的旁链路授权。此时第一信息中的第二配置旁链路授权为type2对应的旁链路授权。其他实施例中,还可以是第一配置旁链路授权为type2对应的旁链路授权,第二配置旁链路授权为type1对应的旁链路授权。
在又一可选实施例中,上述第一配置旁链路授权可以理解为某一个configued sidelink grant称为第一配置旁链路授权,对于其他configued sidelink grant和动态调度称为其他调度。
本公开实施例通过根据目标资源配置确定目标资源,在目标资源上发送第一旁链路信息或者第一旁链路信息与第一信息的复用信息,从而明确了旁 链路信息的传输方式,实现了旁链路信息的传输。
需要说明的是,目标旁链路信息中HARQ码本的确定可以根据终端实际发生的旁链路传输确定,也可以根据可能发生(即包含实际发生和实际未发生)的旁链路传输确定。以下针对终端实际发生旁链路传输和终端实际未发生旁链路传输的情况下HARQ码本的确定方式进行详细说明。
例如,在一可选实施例中,上述在K个周期或者K个传输位置内未发生旁链路传输的情况下,所述目标旁链路信息不包括第一混合自动重传请求HARQ码本或所述第一HARQ码本映射的HARQ码本,所述第一HARQ码本为配置旁链路授权对应的HARQ码本;
或者,在K个周期或者K个传输位置内未发生旁链路传输的情况下,所述目标旁链路信息包括所述第一HARQ码本或所述第一HARQ码本映射的HARQ码本,且所述第一HARQ码本的各比特均指示固定状态;
其中,K为正整数。
需要说明的是,在本实施例中,可能是一个授权(grant)对应一个目标资源(例如,每一个配置旁链路授权可以对应一个第一HARQ码本),也有可能是多个grant对应一个目标资源。可能是一个grant内的一个传输位置(transmission occasion)对应一个目标资源,也可能是一个grant内的多个传输位置对应一个目标资源。可能是一个传输位置上的多个grant的对应一个目标资源,也可能是多个传输位置上的多个grant的对应一个目标资源。当多个位置(或者多个sidelink传输)和一个目标资源关联时,终端将每个位置(或者每个sidelink传输)对应的sidelink信息进行复用并以一个码本的形式发出去。例如,多个grant对应一个目标资源时,终端将每个grant的sidelink信息进行复用并以一个码本的形式发出去。通常存在多个位置或者传输对应的sidelink信息复用后的位图信息才称为码本,但是在本专利中为了方便描述,无论是否出现复用,将复用或者没有复用的sidelink信息都称为码本。例如针对不同位置或者针对不同传输的sidelink信息,或针对不同grant的sidelink信息,这些sidelink信都可以看做是不同的码本。换句话说,上述第一HARQ码本也可以理解为一个传输或者一个位置或者一个grant对应的HARQ-ACK信息,可以包括1个sidelink传输或者一个位置或者一个grant对应的HARQ- ACK信息,也可以理解为多个传输或者多个位置或者多个grant对应的HARQ-ACK信息,即也可以包括多个传输或者多个位置或者多个grant对应的HARQ-ACK信息。1个sidelink传输或者一个位置或者一个grant对应的HARQ-ACK信息中可能包含1个比特或者多个比特。
上述目标旁链路信息包括所述第一HARQ码本或所述第一HARQ码本映射的HARQ码本可以理解为:在通过目标资源传输目标旁链路信息时,需要对终端确定或者接收到的旁链路信息进行映射后,再进行传输时,目标旁链路信息包括所述第一HARQ码本映射的HARQ码本;当无需进行映射时,可以直接将第一HARQ码本在目标资源上进行传输,此时目标旁链路信息包括所述第一HARQ码本。上述固定状态具体可以为确认字符ACK或非确认字符NACK,在此不做进一步的限定。
本实施例中,上述目标旁链路信息为在K个周期或者K个传输位置的旁链路传输所对应的旁链路信息。可选的,一实施例中,在K个周期或者K个传输位置终端实际未发送旁链路传输或者未收到旁链路传输,因此终端无法获取到对应的sidelink信息,从而第一码本为空集合,因为是空集合或者说因为没有发生传输,所以终端不发第一HARQ码本(但是还可能发其他信息)。另一实施例中,接收终端将对应sidelink信息设置为固定状态(例如全部指示NACK或者全部指示ACK或者指示一个预设的比特或者指示一个预设的比特序列)并发给发送终端,从而对于发送终端来说第一HARQ码本可以不为空集合而是基于接收终端反馈的sidelink信息推出来的,但是因为发送终端知道实际没有发生传输,所以可以不发第一HARQ码本(但是还可能发其他信息)。
在另一可选实施例中,上述目标旁链路信息为在K个周期或者K个传输位置的旁链路传输所对应的旁链路信息。可选的,一实施例中,在K个周期或者K个传输位置终端实际未发送旁链路传输或者未收到旁链路传输,终端将第一HARQ码本中对应这些传输的比特设置为固定状态,例如全部设置为ACK,此时第一码本中对应这些实际未发生传输的位置的比特均指示为ACK。可选地,控制节点在收到第一码本后,针对这些的位置,不会调度重传。
在另一可选实施例中,上述目标旁链路信息为在K个周期或者K个传输 位置的旁链路传输所对应的旁链路信息。可选的,一实施例中,在K个周期或者K个传输位置终端实际未发送旁链路传输或者未收到旁链路传输,终端在确定第一码本后,对第一码本进行映射,发送映射后的码本给控制节点。例如第一HARQ码本中对应这些传输的比特设置为固定状态,可选地全部设置为ACK。并将第一HARQ码本中对应这些传输的比特求与,得到的1bit结果为映射后的码本,此时该bit指示ACK,并将该bit发送给控制节点。可选地,控制节点在收到映射后的码本,由于该码本指示ACK,控制节点不会调度重传。
在另一实施例中,可以设定参考时间点,在参考时间点之后的一个时间窗内如果没有收到传输或者发送了传输但是没有收到针对传输的反馈信息,则码本中对应该窗内位置的HARQ-ACK比特均指示NACK或者均指示ACK。
在另一可选实施例中,在K个周期或者K个传输位置内发生旁链路传输的情况下,所述目标旁链路信息包括第二HARQ码本或所述第二HARQ码本映射的HARQ码本,所述第二HARQ码本为配置旁链路授权对应的HARQ码本;K为正整数。
本实施例中,上述第二HARQ码本与第一HARQ码本的不同在于,第二HARQ码本对应的传输中包含至少一个实际发生的传输,进一步的,还可以包含可能发生但是实际没有发生的传输。第一HARQ码本对应的传输中包含可能发生但是实际没有发生的传输。
可选的,所述第二HARQ码本的比特数为以下任一项:
第一预设值;
实际发生传输的旁链路传输中第一传输单位的数量;
所述第一传输单位的数量与第二预设值中的最小值。
其中,在所述第二HARQ码本的比特数为第一预设值时,相当于传输固定比特的HARQ码本。在所述第二HARQ码本的比特数为实际发生传输的旁链路传输中第一传输单位的数量,HARQ码本的比特数可变。在所述第二HARQ码本的比特数为所述第一传输单位的数量与第二预设值中的最小值时,第二预设值用于限定传输的HARQ码本的比特数的最大值。
上述第一预设值和第二预设值的大小可以根据实际需要进行设置,本实 施例中,上述第一预设值和第二预设值可以是控制节点配置(或指示)的,协议定义的,预配置的、终端间协商的或者其他终端指示的,在此不做进一步的限定。上述第一传输单位可以为传输块(Transport Block,TB),也可以为码块组(Code Block Group,CBG)。一次旁链路传输中包含一个或者多个TB,其中如果配置为按照CBG的形式传输,一个TB可以包括多个CBG。上述K的大小可以根据实际需要进行设置,在此不做进一步的限定。
在一可选实施例中,所述第二HARQ码本的比特数为所述第一预设值的情况下,根据旁链路传输中第二传输单位的接收和解码状态,确定所述第二HARQ码本中与所述第二传输单位对应的比特所指示的目标确认信息。本实施例中,可能存在需要增加冗余比特的情况,例如,实际发生了3TB的传输,固定需要反馈4bit HARQ-ACK时,还需要补充1bit冗余信息。
上述第二传输单位为一个TB,也可以为多个TB,可以为一个CBG,也可以为多个CBG。一个旁链路传输可以对应一个或者多个第二传输单位。本实施例中,每一个旁链路传输对应一个第二HARQ码本,旁链路传输中的每个第二传输单位对应一个第二HARQ码本中的比特,当实际发生旁链路传输的第二传输单位的数量小于或大于第二预设值时,终端均认为实际发生旁链路传输的第二传输单位的数量等于第二预设值,此时反馈第二HARQ码本中的比特的数量为第二预设值。
其中,在一可选实施例中,在所述第二传输单位解码失败的情况下,所述目标确认信息为第一值;
和/或,在所述第二传输单位接收失败的情况下,所述目标确认信息为第二值;
和/或,在所述第二传输单位解码成功的情况下,所述目标确认信息为确认字符。
上述第一值和第二值具体指示的状态可以根据实际需要进行设置,例如本实施例中,该第一值为非确认字符(例如可以使用0指示非确认字符,此时该第二值为0)。该第二值为确认字符(例如可以使用1指示非确认字符,此时该第二值为1)。当然,在其他实施例中,该第一值可以为确认字符,第二值可以为非确认字符。或者在其他实施例中,第一值和第二值指示相同的 状态(NACK或者ACK)。应理解,上述接收失败是指没有接收到对应的第二传输单位或者没有接收到传输中的控制信令,例如SCI。
需要说明的是,一个configured sidelink grant上的sidelink传输进行重传时,终端确定重传的调制与编码策略(Modulation and Coding Scheme,MCS)的方法包含以下至少一项:
重传采用的MCS和激活该configured sidelink grant的调度信令中指示的MCS一致。进一步可选地,重传采用的MCS和最近一次收到的激活该configured sidelink grant的激活信令中MCS一致。
或者,重传采用的MCS和激活该configured sidelink grant后该sidelink传输的初传时采用的MCS一致。
或者,重传采用的MCS和激活该configured sidelink grant后位于冗余版本RV(Redundancy Version)=0的该sidelink传输采用的MCS一致,进一步可选地,重传采用的MCS和激活该configured sidelink grant后,距离重传最近一个位于RV=0的该sidelink传输采用的MCS一致。
需要说明的是,一个configured sidelink grant上的sidelink传输进行重传时,终端确定重传的传输块大小TBS(transmission block size)的行为包含以下至少一项:
重传时的TBS基于激活该configured sidelink grant后该sidelink传输的初传确定。例如重传时的TBS和激活该configured sidelink grant后该sidelink传输的初传时的TBS相同,或者重传时的TBS基于激活该configured sidelink grant后该sidelink传输的初传时采用的MCS确定。
或者,重传时的TBS基于激活该configured sidelink grant后位于RV=0的该sidelink传输确定。例如重传时的TBS和激活该configured sidelink grant后位于RV=0的该sidelink传输的TBS相同,或者重传时的TBS基于激活该configured sidelink grant后位于RV=0的该sidelink传输采用的MCS来确定。进一步可选地,重传时的TBS基于激活该configured sidelink grant后,距离重传最近的一个位于RV=0的该sidelink传输来确定。例如重传时的TBS和激活该configured sidelink grant后距离重传最近的一个位于RV=0的该sidelink传输的TBS相同,或者重传时的TBS基于激活该configured sidelink  grant后距离重传最近的一个位于RV=0的该sidelink传输采用的MCS来确定。
或者,重传时的TBS基于激活该configured sidelink grant的调度信令来确定。进一步可选地,重传时的TBS基于最近一次收到的激活该configured sidelink grant的激活信令来确定,例如重传时的TBS基于最近一次收到的激活该configured sidelink grant的激活信令中的MCS来确定(the TBS shall be determined from the most recent PDCCH scheduling the configured sidelink grant Type 2 PSSCH),或者重传时的TBS基于最近一次收到的激活该configured sidelink grant的激活信令调度的sidelink传输的TBS相同。
上述configured sidelink grant的激活可以是指通过调度信令激活,也可以是指configured sidelink grant配置生效。
进一步的,所述目标旁链路信息中的HARQ码本为第一旁链路传输对应的第一HARQ-ACK信息,或者所述第一HARQ-ACK信息映射的信息;
其中,所述第一旁链路传输为所述终端的旁链路传输。
本实施例中,终端进行旁链路信息发送时,可以仅针对终端自己的旁链路传输对应的旁链路信息进行发送。也就是说,上述第一旁链路传输为所述终端需要进行发送或接收的旁链路传输。具体的,第一旁链路传输可以包括实际发生的旁链路传输和实际未发生的旁链路传输。
可选的,所述第一HARQ-ACK信息为所述终端获取的HARQ-ACK信息。
可选的,当所述第一HARQ-ACK信息为多个时,对多个所述第一HARQ-ACK信息进行级联。
进一步的,在所述终端未获取到所述第一HARQ-ACK信息的情况下,根据以下至少一项确定所述第一HARQ-ACK信息:
在反馈机制为机制1的情况下,所述第一HARQ-ACK信息中所有比特为第三值;
在反馈机制为机制2的情况下,所述第一HARQ-ACK信息中所有比特为第四值。
上述第三值和第四值具体指示的状态可以根据实际需要进行设置,例如 本实施例中,该第三值为非确认字符(例如可以使用0指示非确认字符,此时该第四值为0)。该第四值为确认字符(例如可以使用1指示非确认字符,此时该第四值为1)。当然,在其他实施例中,该第三值可以为确认字符,第四值可以为非确认字符。或者在其他实施例中,第三值和第四值指示相同的状态(NACK或者ACK)。
此外,还可以根据组播与单播的情况确定所述第一HARQ-ACK信息中所有比特的值,或者结合组播、单播和反馈机制进行确定。例如,在所述终端未获取到所述第一HARQ信息的情况下,根据以下一项确定所述第一HARQ信息:
在所述第一旁链路传输为组播且反馈机制为机制1的情况下,所述第一HARQ信息中所有比特为确认字符;
在所述第一旁链路传输为组播且反馈机制为机制1的情况下,所述第一HARQ信息中所有比特为非确认字符。
又例如,在所述终端未获取到所述第一HARQ信息的情况下,根据以下一项确定所述第一HARQ信息:
在所述第一旁链路传输为组播且反馈机制为机制2或者所述第一旁链路传输为单播的情况下,所述第一HARQ信息中所有比特为确认字符。
在所述第一旁链路传输为组播且反馈机制为机制2或者所述第一旁链路传输为单播的情况下,所述第一HARQ信息中所有比特为非确认字符。
进一步的,所述在所述目标资源上发送目标旁链路信息之前,所述方法还包括:

进一步的,所述目标资源上传输的HARQ码本中各比特指示的确认信息,与配置旁链路授权的HARQ码本对应的位置的HARQ-ACK信息对应。
本实施例中,每一比特指示的确认信息包括NACK和ACK两种状态中的一种。上述目标资源上传输的HARQ码本中各比特可以由目标资源上传输的HARQ码本中各比特进行一一映射,或者压缩,或者扩展得到。可选的,当采用一一映射时,所述目标资源上传输的HARQ码本中各比特指示的确认信息,与配置旁链路授权的HARQ码本对应的位置的HARQ-ACK信息指示的确认信息相同(即是NACK或者ACK)。可选地,扩展包含比特填充和重复中的至少一项。
可选的,所述目标资源上传输的HARQ码本满足以下条件的至少一项:
对于同一个第一目标配置旁链路授权,所述第一目标配置旁链路授权对应的HARQ-ACK比特在码本中的编号,和第一目标比特在码本中的编号相同,所述第一目标比特为所述第一目标配置旁链路授权的配置生效后,第一次反馈所述第一目标配置旁链路授权对应的HARQ-ACK比特;

对于同一个所述第二目标配置旁链路授权,所述第二目标配置旁链路授权对应的HARQ-ACK比特在码本中的编号,和第三目标比特在码本中的编号相同,所述第三目标比特为激活所述第二目标配置旁链路授权后,第一次反馈所述第二目标配置旁链路授权对应的HARQ-ACK比特;
对于同一个所述第二目标配置旁链路授权,去激活所述第二目标配置旁链路授权的调度信令对应的HARQ-ACK比特在码本中的编号,和所述第二目标比特在码本中的编号相同;
其中,所述第一目标配置旁链路授权对应的HARQ-ACK比特在码本中的编号指的是所述第一目标配置旁链路授权中的第一位置(occasion)对应的HARQ-ACK比特在码本中的编号(即在比特位图中的编号或者顺序);所述第二目标配置旁链路授权对应的HARQ-ACK比特在码本中的编号指的是所述第二目标配置旁链路授权中的第二位置(occasion)对应的HARQ-ACK比特在码本中的编号(即在比特位图中的编号或者顺序)。
第一位置是和码本对应的位置,例如第一位置可以是第一目标配置旁链路授权上的一个或者多个传输位置,可以是第一目标配置旁链路授权上的一个或者多个sidelink传输的位置,可以是第一目标配置旁链路授权上的一个或者多个sidelink传输对应的sidelink信息的位置。
第二位置是和码本对应的位置,例如第二位置可以是第二目标配置旁链路授权上的一个或者多个传输位置,可以是第二目标配置旁链路授权上的一个或者多个sidelink传输的位置,可以是第二目标配置旁链路授权上的一个或者多个sidelink传输对应的sidelink信息的位置。
例如第一目标配置旁链路授权配置生效后,在时间t0,第一目标配置旁链路授权配置上发生了一次sidelink传输,该传输对应的HARQ-ACK bit是该传输对应的码本中的第一个比特。在时间t0+5和t0+12,第一目标配置旁链路授权上发生了两次sidelink传输,这两个sidelink传输可以认为是两个第 一位置,这两个第一位置对应的HARQ-ACK bit也是其各自所在码本中的第一个比特。
例如第二目标配置旁链路授权配置生效后,时间t0的调度信令激活第二目标配置旁链路授权配置,该调度信令对应的HARQ-ACK bit是对应的码本中的第一个比特。在时间t+20的调度信令去激活第二目标配置旁链路授权,这个调度信令可以认为是一个第二位置,这个位置对应的HARQ-ACK bit也是其所在码本中的第一个比特。
其中,所述第一目标配置旁链路授权的类型为配置旁链路授权类型1,所述第二目标配置旁链路授权的类型为配置旁链路授权类型2。
进一步的,所述目标资源包括根据所述目标旁链路信息的数据量选择的传输资源。
本实施例中,所述目标资源可传输的数据量大于或等于第一数据量;
其中,所述第一数据量为所述目标旁链路信息的数据量。
可选的,为了避免资源浪费,所述目标资源为所述第一配置旁链路授权对应的第一传输资源中,可传输的数据量与所述第一数据量之间的差值最小的传输资源。
例如,上述第一传输资源可传输的数据量包括1bit、2bit、4bit和5bit。若上述第一数据量为3bit时,采用4bit的第一传输资源作为目标资源。
可选的,还可以根据资源的类型选择对应的传输资源作为目标资源。例如,在所述目标旁链路信息为所述复用信息的情况下,所述目标资源为以下任一项:
在所述第一信息包括至少一个第二配置旁链路授权对应的第二旁链路信息、且不包括动态调度对应的第三旁链路信息的情况下,所述目标资源为所述第一配置旁链路授权对应的传输资源或所述第二配置旁链路授权对应的传输资源;
在所述第一信息包括所述第三旁链路信息、且不包括所述第二旁链路信息的情况下,所述目标资源为所述第一配置旁链路授权对应的传输资源或动态调度对应的传输资源;
在所述第一信息包括所述第二旁链路信息和所述第三旁链路信息的情况 下,所述目标资源为配置旁链路授权对应的传输资源或动态调度对应的传输资源。
本实施例中,选择的目标资源也可以满足对数据量要求。即所述目标资源可传输的数据量大于或等于第二数据量;其中,所述第二数据量为所述复用信息的数据量。进一步的,所述目标资源为所述第一配置旁链路授权对应的第一传输资源中,可传输的数据量与所述第二数据量之间的差值最小的传输资源。
需要说明的是,上述第一旁链路信息与第一信息进行复用的条件可以根据实际需要进行设置,例如,在一可选实施例中,在所述第一旁链路信息对应的第一资源和所述第一信息对应的第二资源满足预设条件的情况下,所述目标旁链路信息为所述复用信息,所述预设条件包括以下至少一项:
所述第一资源与所述第二资源部分或者全部重叠;

上述同一时域范围,可以指相同的时隙(slot)或子时隙(subslot)或时间窗或定时器(Timer)等。例如第一资源所在的slot中不会存在第二资源,或者第一资源的时域位置开始的一个时间窗内不会存在第二资源,或者以第一资源为参考点开启的一个定时器过期(expire)前不会存在第二资源等,同一频域范围可以指同一个带宽(例如20RB)或者相同带宽部分(bandwidth part,BWP)或者相同载波或者相同资源池或者相同子信道。上述第三预设值和第四预设值的大小可以根据实际需要进行设置,在本实施例中,上述第三预设值大于第四预设值。需要说明的是,上述预设条件可以包括以上一项或者多项,当包括多项时,可以理解为同时满足所有的条件,确定第一旁链路信息与第一信息进行复用,在目标资源上传输的目标旁链路信息为复用信息。
为了更好的理解本公开,以下通过sidelink终端(以下简称终端)将sidelink信息(以sidelink HARQ-ACK信息为例进行说明)发送给控制节点为例,对本公开的实现过程进行详细说明。
其中,终端可以包括发送终端(发送sidelink传输的终端)和接收终端(接收sidelink传输的终端)。上述控制节点可以支持sidelink链路和/或Uu链路,其中,终端将sidelink信息映射为目标通知信息,若通过sidelink链路发送至控制节点时,该控制节点可以称之为sidelink控制节点,目标通知信息可以理解为sidelink HARQ-ACK信息;若通过Uu链路发送至控制节点时,该控制节点可以称之为Uu控制节点,目标通知信息可以理解为Uu HARQ-ACK信息。当然,sidelink HARQ-ACK信息和Uu HARQ-ACK信息仅用于对终端通过不同的链路传输的HARQ-ACK信息进行区分,并不用于限定传输的内容。也有可能sidelink HARQ-ACK信息与Uu HARQ-ACK信息统称为HARQ-ACK信息。
控制节点为4G基站或者LTE基站的时候,控制节点可以调度NR sidelink或者LTE sidelink。当这种控制节点调度NR sidelink时,传输码本的目标资源为LTE PUCCH或者PUSCH资源。控制节点为4G基站或者LTE基站且调度NR sidelink的时候,可以配置configured sidelink grant type1给LTE sidelink终端。
控制节点为5G或者以后版本的基站的时候,控制节点可以调度NR sidelink或者LTE sidelink。控制节点为5G或者以后版本的基站且调度LTE sidelink的时候,可以通过配置configured sidelink grant type2给LTE sidelink终端并通过DCI进行激活去激活。调度NR sidelink的时候,可以通过配置configured sidelink grant type1和/或configured sidelink grant type2给NR sidelink终端。
应理解,终端获取sidelink信息的情况包括:
情况1:发送终端发送sidelink传输,接收终端接收sidelink传输并确定对应的sidelink HARQ-ACK信息,接收终端通过PSFCH或者PSSCH将sidelink HARQ-ACK信息反馈给发送终端,发送终端接收对应至少一个sidelink传输的sidelink HARQ-ACK信息或者接收来自至少一个接收终端的 sidelink HARQ-ACK信息,这些信息为sidelink信息。此时由发送终端向控制节点报告。
情况2:接收终端接收至少一个sidelink传输并确定对应的sidelink HARQ-ACK信息,这些信息为sidelink信息,此时由RX UE向控制节点报告。
发送终端或者接收终端将sidelink信息映射为目标通知信息;当控制节点为Uu控制节点时,将映射后的信息通过目标资源(上行资源)报告给控制节点,例如基站;当控制节点为sidelink控制节点时,将映射后的信息通过目标资源(sidelink资源)报告给sidelink控制节点。
无论是发送终端还是接收终端,以下统称为终端,对终端进行sidelink信息发送的过程进行详细说明。
一、关于sidelink信息复用:
终端获取目标资源配置,并根据目标资源配置确定目标资源;该,新哦啊跑资源配置可以是控制节点配置(或指示)的,协议定义的,预配置的、终端间协商的或者其他终端指示的。
方案1、可以根据传输信息的bit大小或者bit大小区间选择至少一个目标资源集或目标资源用于发送。
对于configured sidelink grant,根据configured sidelink grant上的sidleink传输对应的sidelink信息(例如HARQ-ACK信息)的bit大小或者bit大小区间选择至少一个目标资源集或目标资源用于发送;
当configured sidelink grant和其他调度对应的sidelink信息复用时,根据复用信息bit大小或者bit大小区间选择至少一个目标资源集或目标资源用于发送复用信息。
在一实施例中,假如为一个configured sidelink grant配置了两个目标资源set,set1内的所有资源能够承载的信息bit数处于区间1内,set2内的所有资源能够承载的信息bit数处于区间2内。
当终端需要反馈针对configured sidelink grant上sidelink传输的sidelink信息时,根据sidelink信息的大小选择对应的set,例如终端需要反馈针对configured sidelink grant上sidelink传输的sidelink信息bit数位于区间1,则选择set1进行发送;进一步,如果和其他调度(例如动态调度或者其他 configured sidelink grant)的sidelink传输的sidelink信息进行复用时,基于复用后sidelink信息的bit数在set1和set2中选择一个,例如复用后sidelink信息的bit数位于区间2,则选择set2进行发送。
在另一实施例中,假如配置了一个configured sidelink grant两个资源,资源1能够承载的信息bit数处于区间1内,资源2内的所有资源能够承载的信息bit数处于区间2内。
当终端需要反馈针对configured sidelink grant上sidelink传输的sidelink信息时,根据sidelink信息的大小选择对应的资源,例如终端需要反馈针对configured sidelink grant上sidelink传输的sidelink信息bit数位于区间1,则选择资源1进行发送;进一步,如果和其他动态调度的sidelink传输的sidelink信息进行复用时,基于复用后sidelink信息的bit数在资源1和资源2中选择一个,例如复用后sidelink信息的bit数位于区间2,则选择资源2进行发送。
其中,对于configured sidelink grant,如果其对应的第一资源和其他调度(其他configured sidelink grant和或动态调度)对应的第二资源满足预定条件,此时终端将configured sidelink grant对应的sidelink信息和其他调度对应的sidelink信息复用发送。该预设条件可以包括以下至少一项:
所述第一资源与所述第二资源部分或者全部重叠;
所述第一资源与所述第二资源处于同一目标范围,所述目标范围包括时域范围和频域范围其中至少之一;
所述第一资源的资源总数与所述第二资源的资源总数之和大于第三预设值;
所述第一资源的资源总数大于第四预设值;
所述第二资源的资源总数大于所述第四预设值;
所述第一资源与所述第二资源均为长格式资源。
例如,第一资源和第二资源处于同一个slot且总数超过2时,需要复用configured sidelink grant和其他调度对应的sidelink信息;
可选的,第一资源和第二资源处于同一个slot且configured sidelink grant和其他调度对应的sidelink信息都包含HARQ-ACK时,需要复用configured sidelink grant和其他调度对应的sidelink信息。
方案2,在复用发送的情况下,对应目标资源的确定还可以根据资源的类型选择目标资源。
在一可选实施例中,当configured sidelink grant对应的目标资源和动态调度对应的目标资源满足预定条件时,终端将configured sidelink grant对应的sidelink信息和动态调度对应的sidelink信息在configured sidelink grant对应的目标资源上复用发送。或者终端将configured sidelink grant对应的sidelink信息和动态调度对应的sidelink信息在动态调度对应的目标资源上复用发送。
在另一可选实施例中,当至少两个configured sidelink grant对应的目标资源满足预定条件时,终端将configured sidelink grant对应的sidelink信息在其中一个configured sidelink grant对应的目标资源上复用发送。
例如,当至少两个configured sidelink grant对应的目标资源满足预定条件时,此时终端将这些configured sidelink grant对应的sidelink信息在其中一个configured sidelink grant对应的目标资源上复用发送。
可选的,这些configured sidelink grant中id最小的configured sidelink grant;
可选的,这些configured sidelink grant中id最大的configured sidelink grant;
可选的,这些configured sidelink grant中transmission occasion出现最晚的configured sidelink grant;
可选的,这些configured sidelink grant中周期最小的configured sidelink grant;
可选的,这些configured sidelink grant中周期最大的configured sidelink grant;
可选的,这些configured sidelink grant中对应的sidelink信息反馈资源的周期最小的configured sidelink grant;具体地,这些configured sidelink grant中对应的PSFCH周期最小的configured sidelink grant;
可选的,这些configured sidelink grant中对应的sidelink信息反馈资源的密度最大的configured sidelink grant;具体地,这些configured sidelink grant中对应的PSFCH时域密度最大的configured sidelink grant;或者具体地,这些 configured sidelink grant中对应的PSFCH频域FDM数最大的configured sidelink grant;
可选的,这些configured sidelink grant中对应的sidelink信息反馈资源的周期最大的configured sidelink grant;具体地,这些configured sidelink grant中对应的PSFCH周期最大的configured sidelink grant;
可选的,这些configured sidelink grant中对应的sidelink信息反馈资源的密度最小的configured sidelink grant;具体地,这些configured sidelink grant中对应的PSFCH时域密度最小的configured sidelink grant;或者具体地,这些configured sidelink grant中对应的PSFCH频域FDM数最小的configured sidelink grant。
应理解,上述方案2与方案1可以结合使用,即方案2中选择的目标资源满足方案1中的数量要求。
需要说明的是,对于一个周期P,每个周期P内包含M个传输位置(transmission occasion)的configured sidelink grant,在K个周期或者K个传输位置内的transmission occasion的sidelink传输(sidelink传输包含实际发生和未发生的传输中的至少一项,传输为发送或者接收),终端包含以下行为(K为正整数)之一:
终端在这些occasion上传输固定个数的TB,即传输N_TB个TB,例如N_TB=1,即相同的TB。例如,传输同一个TB的不同RV版本,或者重复(repetition)传输同一个TB;
终端在这些occasion上可以传输的TB数不超过N_TB_MAX个。
二、如何确定configured sidelink grant的HARQ码本。
2.1对于实际发生的sidelink传输,反馈bit的确定。
以在K个周期内的transmission occasion的sidelink传输的情况进行举例:
1.对于一个周期内包含M个transmission occasion的configured sidelink grant,其K个周期内的所有transmission occasion,可能存在以下情况:
K个周期内的所有transmission occasion用于传输N_TB个TB,例如N_TB=1,即同一个TB的传输。例如K=1,即一个周期内的transmission  occasion只能传输一个TB;
或者,K个周期内的所有transmission occasion最多用于N_TB_MAX个TB的传输(实际传输的TB是可能少于或者等于N_TB_MAX)。例如,K=1,N_TB_MAX=2,即一个周期内的transmission occasion最多可以用于传输2个TB,具体用于1个还是2个TB传输取决于发送终端;
或者,没有任何TB数的限制。
可选的,对于接收终端,如果终端在K个周期内的至少一个transmission occasion上收到了sidelink传输,终端可以基于接收和解码状态确定这个K个周期对应的HARQ-ACK信息。
方式1,如果K个周期内的所有transmission occasion用于传输N_TB(固定值)个TB,例如N_TB=1,即同一个TB的传输。此时,基于接收和解码状态,这个K个周期对应的HARQ-ACK信息为N_TB bit ACK/NACK。a)例如N_TB=1时,解码成功对应1bit ACK,否则对应1bit NACK。
方式2,如果K个周期内的所有transmission occasion最多用于N_TB_MAX个TB的传输,这个K个周期对应的HARQ-ACK信息为N_TB_MAX bit ACK/NACK。此时可以反馈最大比特数N_TB_MAX bit或者实际收到的TB数N_actual。
当反馈N_TB_MAX bit时:针对收到的N_actual个TB,基于每个TB的接收和解码状态确定分别确定其对应的HARQ-ACK,从而确定N_TB_MAX bit HARQ-ACK,对于没有收到的TB,全部对应固定状态,例如ACK,从而确定N_TB_MAX-N_actual个ACK,并最终确定N_TB_MAX bit的HARQ-ACK信息。例如N_TB_MAX=4,但是只收到了3个TB且都解失败了,此时这个K个周期对应的HARQ-ACK信息为3bit NACK和1bit ACK。
或者,当反馈N_TB_MAX bit时:针对收到的N_actual个TB,基于每个TB的接收和解码状态确定分别确定其对应的HARQ-ACK,从而确定N_TB_MAX bit HARQ-ACK,对于没有收到的TB,全部对应固定状态,例如NACK,从而确定N_TB_MAX-N_actual个NACK,从而最终确定N_TB_MAX HARQ-ACK信息。例如N_TB_MAX=4,但是只收到了3个TB且都解失败了,此时这个K个周期对应的HARQ-ACK信息为4bit NACK。
当反馈N_actual bit时:针对收到的N_actual个TB,基于每个TB的接收和解码状态确定分别确定其对应的HARQ-ACK,反馈N_actual HARQ-ACK信息。例如,N_TB_MAX=4,但是只收到了N_actual=3个TB且分别对应为NACK、NACK和ACK,此时这个K个周期对应的HARQ-ACK信息为3bit且分别对应NACK、NACK和ACK。
方式3,没有任何TB数的限制:
反馈N_actual bit:针对收到的N_actual个TB,基于每个TB的接收和解码状态确定分别确定其对应的ACK/NACK,反馈N_actual bit HARQ-ACK信息。例如,只收到了N_actual=3个TB且分别对应为NACK、NACK和ACK,此时这个K个周期对应的HARQ-ACK信息为3bit且分别对应NACK、NACK和ACK。
方式4,如果K个周期内的每个transmission occasion对应一个HARQ-ACK比特,如果该occasion收到传输并解码则将对应比特设置为ACK,如果收到但是解码失败将对应比特设置为NACK。如果没有收到则设置为ACK,或者如果没有收到则设置为NACK。
对于在K个transmission occasion的sidelink传输的情况,确定configured sidelink grant的HARQ码本和上面K个周期的情况类似,不做赘述。
进一步的,终端还可能包含的行为有:
终端在对应的第一目标资源上将HARQ-ACK信息发送给控制节点;
和/或,终端在对应的第二目标资源上将HARQ-ACK信息发给发送终端。
可选的,对于发送终端,终端在K’个周期内的至少一个transmission occasion上发生了sidelink传输(一个或者多个),此时行为包含以下一种:
一实施例中,如果终端在第二目标资源收到至少一个HARQ-ACK信息,进一步基于收到的HARQ-ACK信息确定sidelink信息中针对自己发送的sidelinK传输的HARQ-ACK bit(s),并对应的目标资源上发送sidelink信息。
例如,Sidelink信息中针对自己发送的sidelink传输的HARQ-ACK bit(s)等于第二目标资源上收到的HARQ-ACK信息。假设收到ACK则设置为ACK,收到NACK则设置为NACK,收到一个HARQ-ACK bitmap则将Sidelink信息中对应该sidelink传输的HARQ-ACK bits的值设置为该bitmap。进一步的, 如果收到了多个HARQ-ACK信息,则将他们级联,Sidelink信息中针对自己发送的sidelink传输的HARQ-ACK bit(s)等于级联后的bitmap。
在另一实施例中,可以将第二目标资源上收到的HARQ-ACK信息内的所有bit求与或者位与,Sidelink信息中针对自己发送的sidelinK传输的HARQ-ACK bit等于求与或者位与结果。例如K=K’=1,在一个周期内终端发送了N_TB_MAX=4个TB,接收终端反馈4bit,收到了这4个TB的HARQ-ACK信息且分别对应ACK、NACK、NACK和NACK,将他们求与,从而得到1bit NACK,将Sidelink信息中对应该sidelink传输的HARQ-ACK bit等于NACK。
在又一实施例中,如果终端在第二资源没有收到HARQ-ACK信息。可以根据反馈机制确定sidelink信息。例如:
如果发送的sidelinK传输为组播且反馈机制为机制1,终端将Sidelink信息中自己发送的sidelinK传输对应的HARQ-ACK bit(s)全部设置为ACK,并对应的目标资源上发送sidelink信息;
如果发送的sidelinK传输为组播且反馈机制为机制2或者如果发送的sidelinK传输为单播,终端将Sidelink信息中自己发送的sidelinK传输对应的HARQ-ACK bit(s)全部设置为NACK,并对应的目标资源上发送sidelink信息。
在又一实施例中,如果终端在第二目标资源上没有收到HARQ-ACK信息,终端不发送针对自己发送的sidelinK传输的sidelink信息。
2.2对于没有实际发生的sidelink传输,反馈bit的确定。
如果终端在K’个周期内的所有transmission occasion都没有发送sidelink传输或者收到sidelink传输;一实施例中,终端在对应的目标资源上不发送针对该configured sidelink grant的该K个周期的HARQ-ACK信息(但是可能发其他调度的信息),可选地K’=1。另一实施例中,终端将Sidelink信息中对应该configured sidelink grant的该K’个周期的HARQ-ACK bit(s)全部设置为ACK,并对应的目标资源上发送sidelink信息。
具体的,反馈时可以采用半静态码本或动态码本。
可选的,如果configured sidelink grant使用半静态码本向控制节点发送sidelink信息。configured sidelink grant对应的目标资源的周期=β*configured  sidelink grant周期(即每β个周期P都有对应的目标资源,每β个周期向控制节点发送这β个周期内的sidelink信息)。
可选的,如果终端在一个configured sidelink grant的K’个周期内所有transmission occasion都没有收到sidelink传输,可以设置对应该configured sidelink grant的该K’个周期的HARQ-ACK bit(s)全部为ACK。
进一步的,还可能包含的行为有:终端在对应的第一目标资源上将HARQ-ACK信息发送给控制节点;和/或,终端在对应的第二目标资源上将HARQ-ACK信息发给发送终端。
可选的,如果终端在一个configured sidelink grant的K’个周期内所有transmission occasion都没有发送sidelink传输,此时,在一实施例中,如果终端在第二目标资源收到了针对该configured sidelink grant的该K’个周期的HARQ-ACK信息,确定发给控制节点的sidelink信息,并对应的目标资源上发送sidelink信息,其中确定sidelink信息的方法包含:Sidelink信息中对应该configured sidelink grant的该K’个周期的HARQ-ACK bit(s)=第一资源上收到的HARQ-ACK信息;或者,将第一资源上收到的HARQ-ACK信息内的所有bit求与或者求位与),Sidelink信息中对应该configured sidelink grant的该K’个周期的HARQ-ACK bit=求与结果或者求位与结果(例如针对该configured sidelink grant的该K’个周期,终端收到了4个ACK,将他们求与,从而得到1bit ACK,将Sidelink信息中对应该sidelink传输的HARQ-ACK bit=ACK)。
在另一实施例中,无论终端在第二目标资源是否收到HARQ-ACK信息,终端将Sidelink信息中对应该configured sidelink grant的该K’个周期的HARQ-ACK bit(s)全部设置为ACK,并对应的目标资源上发送sidelink信息。
可选的,如果configured sidelink grant使用动态码本向控制节点发送sidelink信息。configured sidelink grant对应的目标资源的周期和configured sidelink grant周期相同(即每个周期P都有对应的目标资源,每个周期向控制节点发送)。
可选地,configured sidelink grant对应的第二目标资源的周期和configured sidelink grant周期相同或者为configured sidelink grant周期的因数(即每个周 期P都有对应的第一资源,每个周期进行反馈)。
可选的,如果终端在K’个周期内的所有transmission occasion都没有发送sidelink传输或者收到sidelink传输。此时,终端在对应的目标资源上不发送针对该configured sidelink grant的该K个周期的HARQ-ACK信息(但是可能发其他调度的信息),可选地K’=1;或者,终端将Sidelink信息中对应该configured sidelink grant的该K’个周期的HARQ-ACK bit(s)全部设置为ACK,并对应的目标资源上发送sidelink信息。
