为了便于理解,以下对本公开实施例涉及的一些内容进行说明:
混合自动选择重传(Hybrid Automatic Repeat Request,HARQ)机制:
控制节点和UE(也可以称为终端设备)通过Uu接口并使用上下行链路(即Uplink and Downlink)进行通信,UE和UE之间通过PC5接口并使用旁链路(即Sidelink,也可称为直连链路、副链路、侧链路或边链路等)通信,如图1a所示。
在新空口(New Radio,NR)中,对于下行数据包的传输,UE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HARQ-ACK信息(即NACK或者ACK)来告知控制节点该下行数据包的传输是否成功,如图1b所示,从而帮助控制节点决定是否需要重传。该机制能够有效地提高下行数据传输的可靠度和资源利用率。
在Sidelink上,UE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UE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接口下行数据包的HARQ反馈机制不同的是,Sidelink传输可能并不是在控制节点和UE之间进行的,而是在UE和UE之间的Sidelink上进行的,如图1c所示,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UE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UE在Sidelink上进行重传。进行Sidelink信息报告的UE可以是发送UE,也可以是接收UE,所谓的发送UE、接收UE是指发送、接收该Sidelink信息对应的Sidelink传输的UE。需要注意的是,一个SidelinkUE可能是发送也可能是接收UE。例如在时刻a1该UE发送Sidelink数据,在时刻a2接收其他UE的Sidelink数据。
一个发送UE报告Sidelink HARQ-ACK信息给控制节点的例子,可以如图1d所示。控制节点调度UE 1在Sidelink上发送一个传输块(Transport Block,TB)给UE2。UE2收到该TB但是无法成功解出来,于是在PSFCH上反馈一个NACK。UE1将该Sidelink NACK映射为Uu NACK并在目标资源上发给控制节点。控制节点收到NACK后知道该TB传输失败,因此发送一个调度信令调度UE1在Sidelink上重传该TB。
一个接收UE报告Sidelink HARQ-ACK信息给控制节点的例子,可以如图1e所示。Sidelink接收UE根据收到Sidelink传输并解码确定Sidelink HARQ-ACK信息后,若Sidelink接收UE和控制节点之间存在Uu连接并被分配了对应的目标资源,则可以在目标资源上直接将该Sidelink HARQ-ACK信息发送给控制节点,此时可能不需要通过PSFCH发送给发送UE。在图1e中,UE2向UE1传输NACK加上了方括号表明该步骤可能存在也可能不存 在。
Sidelink中的资源分配模式和控制节点:
在Sidelink中存在两种资源分配模式,分别是调度资源分配(即Scheduled Resource Allocation)模式与自主资源选择(即Autonomous Resource Selection)模式。前者由控制节点控制并为每个UE分配资源,后者由UE自主选择资源。对于某些UE,还可能同时进行两种资源分配模式。
在Sidelink中,控制节点可以是基站、集成接入回程节点(Integrated Access Backhaul,IAB)、用户设备、中继设备(即Relay)或路边单元(Road Side Unit,RSU)等,也可以是一些类似RSU或者IAB的其他网络设施。此外,一些控制节点可以同时支持Sidelink和Uu链路。
上行控制信息(Uplink Control InFormation,UCI)信息:
在第十五版本新空口(即R15NR)中,将UE反馈的上行控制信息统称为UCI,UCI的一个重要组成部分就是HARQ-ACK信息,除此之外,上述UCI还可以包括信道状态信息(Channel State InFormation,CSI)报告、调度请求(Scheduling,SR)等。
UCI可以在PUCCH资源或者PUSCH资源上传输,其中,PUCCH资源可以支持5种格式(即Format),不同Format的特性不同。其中PUCCH Format0以序列的形式承载1或者2bit UCI,时域占据1或者2个符号,频域占用1个资源块(Resource Block,RB)。
Sidelink信息:
对于Sidelink传输的HARQ-ACK信息可以在PSFCH信道上传输,另外Sidelink传输的CSI可以在PSSCH上传输,PSFCH目前已经支持以PUCCH Format 0的序列为基础(但是可能占据的时频域资源量不同,或者引入其他新的特性,或者引入其他新的Format),因此可以称其为PSFCH Format0,需要说明的是,此处并不限于称为PSFCH Format0,也可以根据实际情况称为其他名称。
需要说明的是,为了加以区别,可以将上行链路上传输的上行链路信息的HARQ-ACK信息称为Uu HARQ-ACK信息,可以将Sidelink上传输的HARQ-ACK信息称为Sidelink HARQ-ACK信息。
NR中的UCI复用:
在NR中,如果没有配置码块组(Codeblock Group,CBG)传输,则对应一个TB的HARQ-ACK信息为1bit,该bit如果为1则表示ACK,如果为0则表示NACK。如果控制节点发送了多个TB,且控制节点指示UE将这些TB对应的HARQ-ACK信息在同一个资源上发送给控制节点,则UE可以按照协议规定的方式(例如码本),将这些TB的HARQ-ACK信息复用成为一个新的HARQ-ACK信息(例如一个位图(即Bitmap)),并上报给控制节点。
例如,如图1f所示,控制节点发送了3个TB,其中TB#1和TB#3被UE成功解出,TB#2解码失败,则3个TB对应的HARQ-ACK信息的bit的值分别为1、1和0,分别表示ACK、ACK和NACK。且控制节点指示UE在同一个PUCCH上将这3个TB对应的HARQ-ACK信息的bit发出去,则UE将3个HARQ-ACK信息的bit复用为一个Bitmap 101并发给控制节点。
配置授权(即Configured Grant):
针对低时延业务或者周期业务的需求,NR支持两种上行半静态调度授权的上行传输(即Configured UL Grant)方式:第一类型(即Type1)和第二类型(即Type2)。
Configured UL Grant Type1:Configured UL Grant Type1资源可通过无线资源控制(Radio Resource Control,RRC)信令半静态地配置,用户设备收到该配置后即可以在该配置上根据自身业务到达情况和配置情况进行传输,不需要下行控制信息(Downlink Control Information,DCI)进行动态的调度。
Configured UL Grant Type 2:Configured UL Grant Type 2资源可通过RRC信令半静态地配置,用户设备收到该配置后不能直接使用,控制节点进一步地通过DCI激活该配置后用户设备才能根据该激活DCI使用该授权资源。控制节点还可以通过DCI去激活该配置,收到去激活DCI的用户设备会停止该授权资源。
一个Configured UL Grant通常对应周期性的可以用于UE发送信号的资源,且每个周期内包含多个传输时机(即Transmission Occasion)。相比于常规的动态调度(即Dynamic Grant),Configured UL Grant可以减少信令开销 和交互流程,保证低时延要求。
Sidelink中引入了类似Configured Grant的概念,可以支持两种Configured Sidelink Grant:
第一种:控制节点配置Sidelink资源,不需要额外发送信令进行激活和/或去激活,被配置用户设备可以根据来包状况使用这些资源,该资源配置可以但不限于被称为Configured Sidelink Grant Type1。
第一种:控制节点信令配置Sidelink资源,需要额外发送信令对该资源进行激活和/或去激活,该资源配置可以但不限于被称为Configured Sidelink Grant Type2。
需要说明的是,控制节点可以为用户设备配置多个Configured Sidelink Grant。

以下结合示例对本公开实施例进行说明:
示例一:配置PUCCH或PSFCH
情况一、若上述用于第一旁链路信息(也可称为第一Sidelink信息)的资源是PUCCH,可以通过以下方式中的至少一种配置用于目标旁链路信息的资源:
方式一、配置至少一个用于第一旁链路信息的PUCCH Resource Set。
例如,支持Sidelink的UE最多可以被配置5个PUCCH Resource Set,其中第五个PUCCH Resource Set(或者称为Sidelink PUCCH Resource Set)用于目标Sidelink信息,若该PUCCH Resource Set ID=4记为PUCCH Resource Set 4,即该PUCCH Resource Set中包含的PUCCH Resource用于目标Sidelink信息。
可选地,在允许复用的情况下,UE还可以在该PUCCH Resource Set 4上发送Uu的反馈信息。
可选地,UE不会在该PUCCH Resource Set 4上发送Uu的反馈信息,或者通过控制节点配置或者预配置或者协议定义或者调度保证用于Uu的反馈信息的资源不和PUCCH Resource Set 4上中的资源重叠。
方式二、配置至少一个用于第一Sidelink信息的PUCCH Resource。

可选地,在允许复用的情况下,UE还可以在该PUCCH Resource 30和/或PUCCH Resource31上发送Uu的反馈信息。
可选地,UE不会不在PUCCH Resource 30和PUCCH Resource31上发送Uu的反馈信息,或者通过控制节点配置或者预配置或者协议定义或者调度保证用于Uu的反馈信息的资源不和PUCCH Resource 30以及PUCCH Resource31重叠。
方式三、配置用于NR的PUCCH Resource Set和PUCCH Resource。
NR第十五版本(即NR Release 15)中UE最多可以被配置4个PUCCH Resource Set,每个Set内最多包含8或者32个PUCCH Resource,通过控制节点配置或者预配置或者协议定义或者调度分配用于报告第一sidelink信息 的PUCCH资源和或PUCCH resource set。
可选地,控制节点配置或者预配置或者协议定义或者通过调度保证用于Uu的反馈信息的资源不和配置的用于第一Sidelink信息的PUCCH资源重叠。
可选地,在允许复用的情况下,UE还可以在相同的PUCCH Resource Set和/或Resource上发送Uu的反馈信息。
例如,基站发送DCI调度Sidelink传输,并在DCI中指示PUCCH Resource1用于该Sidelink传输对应的Sidelink信息的报告,此时UE使用PUCCH Resource1用于该Sidelink传输对应的Sidelink信息的报告。
可选地,UE不会在PUCCH Resource1上发送Uu的反馈信息,或者通过控制节点配置或者预配置或者协议定义或者调度保证用于Uu的反馈信息的资源不和该PUCCH Resource1重叠。
本实施例可以通过上述方式配置专用于Sidelink信息报告的PUCCH资源,从而避免和上行链路信息复用。
情况二、若上述用于第一Sidelink信息的资源是PSFCH,可以通过以下方式中的至少一种配置用于第一Sidelink信息的资源:
方式一、配置至少一个用于第一Sidelink信息的PSFCH Resource Set。
例如,若支持Sidelink的UE最多可以被配置5个PSFCH Resource Set,其中ID=4的PSFCH Resource Set(或者称为Sidelink PSFCH Resource Set)用于目标Sidelink信息,即该PSFCH Resource Set中包含的PSFCH Resource用于目标Sidelink信息。
可选地,UE不会在PSFCH Resource Set4上发送第二Sidelink信息,或者通过控制节点配置或者预配置或者协议定义或者调度保证用于第二Sidelink信息的资源不和PSFCH Resource Set4上中的资源重叠。
可选地,在允许复用的情况下,UE还可以在PSFCH Resource Set4上发送第二Sidelink信息。
方式二、配置至少一个用于第一Sidelink信息的PSFCH Resource Set。
例如,若配置的PSFCH Resource Set0中包含了32个PSFCH Resource,其中PSFCH Resource30和PSFCH Resource31(或者称为Sidelink PSFCH Resource)用于第一Sidelink信息,PSFCH Resource0至PSFCH Resource29 用于第二Sidelink信息报告。

可选地,在允许复用的情况下,UE还可以在PSFCH Resource30和/或PSFCH Resource31上发送第二Sidelink信息。
方式三、配置用于NR的PSFCH Resource Set和PSFCH Resource
若UE最多被配置4个PSFCH Resource Set,每个PSFCH Resource Set内最多包含8或者32个PSFCH Resource,通过控制节点配置或者预配置或者协议定义或者调度保证用于第二Sidelink信息的资源不和配置用于第一Sidelink信息的PSFCH资源重叠。
例如,基站发送DCI调度Sidelink传输,并在DCI中指示PSFCH Resource1用于该Sidelink传输对应的Sidelink信息的报告,此时UE使用PSFCH Resource1用于该Sidelink传输对应的Sidelink信息的报告。
可选地,UE不会在PSFCH Resource1上发送第二Sidelink信息,或者通过控制节点配置或者预配置或者协议定义或者调度保证用于第二Sidelink信息的资源不和该PSFCH Resource1重叠。
可选地,在允许复用的情况下,UE还可以在PSFCH Resource1上发送第二Sidelink信息。
本实施例可以通过上述方式配置专用于第一Sidelink信息报告的PSFCH,避免将第一Sidelink信息和第二Sidelink信息进行复用。
示例二:配置PUSCH或PSSCH
情况一、若上述用于Sidelink信息的资源是PUSCH时,可以通过以下方式中的至少一种配置用于第一Sidelink信息的资源:
方式一、配置至少一个用于第一Sidelink信息的Configured UL Grant。
UE可以在配置的Configured UL Grant的Transmission Occasion上发送第一Sidelink信息。
方式二、用于调度该Sidelink传输的调度信令中携带了PUSCH的资源信 息。
UE可以在调度信令对应的PUSCH资源上发送第一Sidelink信息。
本实施例通过上述方式可以配置专用于第一Sidelink信息报告的PUSCH资源,从而避免将Sidelink信息和上行链路信息进行复用。
情况二、若上述用于第一Sidelink信息的资源是PSSCH,可以通过以下方式中的至少一种配置用于第一Sidelink信息的资源:
方式一、配置至少一个用于第一Sidelink信息的Configured Sidelink Grant。
UE可以在配置的Configured Sidelink Grant的Transmission Occasion上发送第一Sidelink信息。
方式二、用于调度该Sidelink传输的调度信令中携带了PSSCH的资源信息。
UE可以在调度信令对应的PSSCH资源上发送第一Sidelink信息。
本实施例通过上述方式可以配置专用于第一Sidelink信息报告的PSSCH资源,从而将第一Sidelink信息和第二Sidelink信息进行复用。
可选地,若为Configured Sidelink Grant配置资源,该资源可以是周期性的。
示例三:配置和/或指示资源
情况一、动态调度。
为了便于描述,以下以用于加扰调度Sidelink传输的调度信令的无线网络临时标识(Radio Network Tempory Identity,RNTI)称为SL-RNTI为例进行说明。
具体地,若调度Sidelink传输的调度信令通过SL-RNTI加扰,UE收到调度信令后发现其RNTI为SL-RNTI,从而知道是调度Sidelink传输的调度信令,基于该调度信令中的资源分配进行Sidelink传输,也即Sidelink发送或Sidelink接收。
可选地,用于调度Sidelink传输的调度信令中包含至少一个用于目标Sidelink信息的资源的标识。这样UE获取或者确定针对该Sidelink传输的HARQ-ACK信息后,可以使用该调度信令指示的资源将该HARQ-ACK信息上报给控制节点。
情况二、Configured Sidelink Grant Type2。
为了便于描述,以下以用于激活Configured Sidelink Grant Type2调度信令RNTI称为SL-CG-RNTI为例进行说明。
若激活Configured Sidelink Grant Type2的调度信令通过SL-CG-RNTI加扰,UE收到调度信令后发现其RNTI为SL-CG-RNTI,从而知道是激活Configured Sidelink Grant Type2的调度信令,基于该调度信令激活Configured Sidelink Grant Type2。
进一步地,UE可以在该激活的Configured Sidelink Grant Type2进行Sidelink传输,也即Sidelink发送或Sidelink接收。
可选地,激活Configured Sidelink Grant Type2的调度信令可以中包含至少一个用于目标Sidelink信息的资源的标识。这样UE使用该激活的Configured Sidelink Grant Type2进行Sidelink传输后,可以获取或者确定针对该Sidelink传输的HARQ-ACK信息,并使用该调度信令指示的资源将该HARQ-ACK信息上报给控制节点。
情况三、配置PUCCH和指示PUCCH。
资源配置信息中包含PUCCH Resource Set x,其中包含m个PUCCH Resource,控制节点发送调度信令指示PUCCH Resource y,指示UE在PUCCH Resource y上发送Sidelink信息。
例如,对于Configured Sidelink Grant Type2,用于激活该Configured Sidelink Grant Type2的调度信令中可以携带一个PUCCH ID,UE使用该PUCCH ID对应的PUCCH上报目标Sidelink信息。
又例如,对于组播传输,且有N个组内接收UE,第二调度信令携带了PUCCH域,该域指示了N个PUCCH,这样接收UE可以在收到该第二调度信令后,根据其自身的ID确定其PUCCH,并使用确定的PUCCH上报;或者发送UE收到该第二调度信令后,根据接收UE的ID,在指示的PUCCH上报告针对该接收UE的Sidelink信息。
可选地,上述根据接收UE的ID确定PUCCH可以包括根据接收UE的ID和PUCCH ID的关联关系确定PUCCH,也可以是根据接收UE的ID和PUCCH域中每个PUCCH对应的位置确定PUCCH。
例如,对于第二调度信令携带的PUCCH域包含N个PUCCH ID,UE ID最小的UE对应N个PUCCH ID中ID最小的PUCCH,UE ID第二小的UE对应N个PUCCH ID中ID第二小的PUCCH,以此类推。
例如,第二调度信令携带的PUCCH域为一个N bit的位图,每个bit对应1个PUCCH,UE ID最小的UE对应位图中第一个bit对应的PUCCH,UE ID第二小的UE对应位图中第二个bit对应的PUCCH,以此类推,需要说明的是,在该情况下位图中N个PUCCH的排序可以不是按照ID大小进行排序的。
需要说明的是,在用于Sidelink信息的资源为PSFCH的情况下,配置PSFCH和指示PSFCH的方式同上述配置PUCCH和指示PUCCH的方式,为避免重复,在此不做赘述。
情况四、配置PUSCH和指示PUSCH。
资源配置信息中包含Sidelink信息在PUSCH中时Sidelink信息的资源分配,其中可以包含m个可选资源分配方案,控制节点发送调度信令指示资源分配y,指示UE使用资源分配y并通过PUSCH发送目标Sidelink信息。
需要说明的是,在用于Sidelink信息的资源为PSSCH的情况下,配置PSSCH和指示PSSCH的方式同上述配置PUSCH和指示PUSCH的方式,为避免重复,在此不做赘述。
具体地,本实施例通过配置和/或指示,确定一个与一个或多个Sidelink传输对应的目标资源,即该一个或多个Sidelink传输对应的Sidelink信息在该目标资源上发送。
例如,对于在时刻n的目标资源,处于时刻n-1和时刻n-delta之间的Sidelink传输对应的Sidelink信息在该目标资源上传输,其中0<=delta<1。
可选地,上述多个Sidelink传输可以对应相同的发送UE,或者上述多个Sidelink传输可以对应相同的接收UE;或上述多个Sidelink传输可以对应相同的对应相同的发送UE和接收UE。
例如,在时刻n-1和时刻n-delta之间UE1给UE2发送了4个TB,若UE2收到4个TB并解码且对应的HARQ-ACK分别为NACK、ACK、ACK和NACK,UE2直接在目标资源上将4个TB对应的HARQ-ACK信息复用 发送,即在目标资源上发送NACK、ACK、ACK和NACK复用后的信息。或者UE2将4个TB对应的HARQ-ACK信息发给UE1,UE1在目标资源上将4个TB对应的HARQ-ACK信息复用发送,即在目标资源上发送NACK、ACK、ACK和NACK复用后的信息。
示例四:偏移信息
资源配置信息可以包含偏移信息,其中偏移信息可以包括一个或者多个偏移值,且含义不同。具体地,上述偏移信息可以包括用于所述目标旁链路信息传输的资源(如资源或资源集)和参考点之间的偏移值。
例如,若上述偏移信息中包括用于所述目标旁链路信息传输的资源所在的Slot相对于SFN0偏移的Slot数或者毫秒数或者帧数,并用O表示,则可以利用满足公式(时间t-SFN0)mod周期=O的时间t上的资源或者资源集报告目标旁链路信息。
例如,若上述偏移信息中包括用于所述目标旁链路信息传输的资源所在的Slot相对于DFN0偏移的Slot数或者毫秒数或者帧数,并用O表示,则可以利用满足公式(时间t-DFN0)mod周期=O的时间t上的资源或者资源集报告目标旁链路信息。
又例如,若偏移信息中包含用于所述目标旁链路信息传输的资源和其对应的Configured Sidelink Grant Type2的激活信令之间的时间差,并用K-SL-1表示,则UE可以使用(Configured Sidelink Grant Type2的激活信令时间n1+K-SL-1)对应的时间上的资源或者资源集)报告目标旁链路信息。
可选地,对于不同Configured Sidelink Grant Type2,K-SL-1值可以不同。
又例如,若偏移信息中包含用于所述目标旁链路信息传输的资源和其对应的Configured Sidelink Grant之间的时间差,并用K-SL-2表示,则UE可以使用(Configured Sidelink Grant时间n2+K-SL-2)对应的时间上的资源或者资源集报告目标旁链路信息。
可选地,上述Configured Sidelink Grant时间n2可能是每L个周期的开始或结束,其中,L为正整数。
又例如,若偏移信息中包含用于所述目标旁链路信息传输的资源和其对应的PSFCH之间的时间差,并用K-SL-3表示,则若用于反馈针对Sidelink 传输的HARQ-ACK信息的PSFCH所在时间为n3,UE使用(PSFCH所在时间n3+K-SL-3)对应的时间上的资源或者资源集报告目标旁链路信息。
又例如,若偏移信息中包含用于所述目标旁链路信息传输的资源和其对应的Sidelink传输之间的时间差,并用K-SL-4表示,则UE可以使用(Sidelink传输所在时间n4+K-SL-4)对应的时间上的资源或者资源集报告目标旁链路信息。
可选地,多个Configured Sidelink Grant基于偏移确定的资源可以是重叠的或者是相同的。
示例五:周期信息
本实施例中,周期信息所包括的相关内容可以参见前述描述。
具体地,目标资源周期为P0,一个目标资源和该目标资源相关的一个或者多个周期内的Sidelink传输位置对应,即多个Sidelink传输对应的Sidelink信息可以在该目标资源上发送,其中,上述Sidelink传输位置可以是实际用于Sidelink传输的位置,也可以是候选的用于Sidelink传输的候选位置(即Candidate Occasion)。
例如,目标资源周期为1ms,对于在时刻n的目标资源,处于时刻n-1ms和时刻n-delta之间的Sidelink传输对应的Sidelink信息在该目标资源上传输,其中0<=delta<1。
可选地,上述多个Sidelink传输可以对应相同的发送UE,或者上述多个Sidelink传输可以对应相同的接收UE;或上述多个Sidelink传输可以对应相同的对应相同的发送UE和接收UE。
例如,在时刻n-1ms和时刻n-delta之间UE1给UE2发送了4个TB,若UE2收到4个TB并解码且对应的HARQ-ACK分别为NACK、ACK、ACK和NACK,UE2直接在目标资源上将4个TB对应的HARQ-ACK信息复用发送,即在目标资源上发送NACK、ACK、ACK和NACK复用后的信息。或者UE2将4个TB对应的HARQ-ACK信息发给UE1,UE1在目标资源上将4个TB对应的HARQ-ACK信息复用发送,即在目标资源上发送NACK、ACK、ACK和NACK复用后的信息。
又例如,一个Configured Sidelink Grant为P,控制节点配置周期为P*α 的PUCCH资源用于报告该Configured Sidelink Grant上的传输对应的HARQ-ACK信息。若α=2,Configured Sidelink Grant周期1内目标UE传输了一个TB且接收UE反馈ACK,周期2内目标UE传输了一个TB且接收UE反馈NACK,此时在对应的PUCCH上目标UE向控制节点报告这两个周期上传输对应的sidelink信息即NACK和ACK,分别对应周期2和周期1,或者报告ACK和NACK,分别对应周期1和周期2。
示例六:通过激活DCI指示资源
对于Configured Sidelink Grant,Configured Sidelink Grant的高层配置中包含了对应的资源配置信息。
可选地,对于Configured Sidelink Grant Type2,控制节点可以通过激活信令指示用于目标旁链路信息传输的资源。
可选地,激活信令可以包含至少一个PUCCH标识和/或至少一个资源集标识。
例如,基站在激活Configured Sidelink Grant Type2的DCI中携带了PUCCH标识ID=0,UE使用ID=0对应的资源发送该Configured Sidelink Grant Type2对应的Sidelink信息。
又例如,基站在激活Configured Sidelink Grant Type2的DCI中携带了目标资源集标识ID=1,UE使用ID=1对应的资源集发送该Configured Sidelink Grant Type2对应的Sidelink信息。
又例如,基站在激活Configured Sidelink Grant Type2的DCI中携带了PUCCH标识ID=1和资源集标识ID=2,UE使用标识ID=2对应的资源集中ID=1对应的资源发送该Configured Sidelink Grant Type2对应的Sidelink信息。
示例七:默认配置
本实施例中,在UE未获取资源配置信息,或者获取的资源配置信息中不包含下述信息的情况下,UE可以通过以下方式中的至少一项确定目标资源:
方式一、不包含Configured Sidelink Grant的资源的资源信息时,认为相对于参考点最近的J个资源为用于反馈Configured Sidelink Grant的HARQ-ACL信息的资源。
其中,J可以由协议预定义、控制节点配置、预配置、终端间协商或其他 终端指示,上述其他终端可以是指除上述第一终端之外的终端。
例如,J=1,当UE在Configured Sidelink Grant上传输后,该传输所在的周期后最近的1个资源用于报告。
方式二、不包含Configured Sidelink Grant的资源的偏移信息时,认为相对于参考点的偏移为固定值,例如0,或者认为用于反馈Configured Sidelink Grant的HARQ-ACK信息最近的资源用于报告,此时偏移值为该最近的资源和参考点之间的偏移值。
例如,认为偏移值=0,当UE在Configured Sidelink Grant上传输后,该传输所在的周期结束时刻上的资源用于报告。
