下面结合附图介绍本公开的实施例。本公开实施例提供的旁链路信息发送方法、接收方法、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5G系统,或者演进型长期演进(Evolved Long Term Evolution,eLTE)系统或者长期演进(Long Term Evolution,LTE)系统,或者后续演进通信系统等。
请参见图1,图1是本公开实施例可应用的一种网络系统的结构图,如 图1所示,包括终端11、终端12和控制节点13,其中,终端11和终端12之间可以通过PC5接口并使用sidelin通信,控制节点13和终端(包含终端11和终端12)之间可以通过空口(Uu)接口并使用上下行链路(uplink and downlink)进行通信。终端11和终端12可以是用户终端(User Equipment,UE)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)、可穿戴式设备(Wearable Device)、智能汽车、车载设备或者机器人等终端侧设备,需要说明的是,在本公开实施例中并不限定终端的具体类型。上述控制节点13可以是网络设备,例如:4G基站,或者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,或者传输接收点(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。或者,上述控制节点13可以是一些集成接入回程节点(Integrated Access Backhaul,IAB),还可以是一些sidelink终端、中继(relay),路边单元(Road Side Unit,RSU),当然,也可以是一些类似RSU或者IAB的其他网络设施。进一步的,一些控制节点13可能支持sidelink或Uu链路,也可能同时支持sidelink和Uu链路,对此本公开实施例不作限定。需要说明的是,在本公开实施例中并不限定控制节点13的具体类型。
另外,在控制节点为4G基站或者LTE基站的情况下,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可以为LTE物理上行控制信道(Physical Uplink Control Channel,PUCCH)或者物理上行共享信道(Physical Uplink Shared Channel,PUSCH)资源。
另外,在控制节点为5G或者以后版本的基站的情况下,控制节点可以调度NR sidelink或者LTE sidelink。
请参见图2,图2是本公开实施例提供的一种旁链路信息发送方法的流程图,该方法应用于终端,如图2所示,包括以下步骤:
步骤201、依据码本信息,获取sidelink信息对应的码本。
其中,上述码本信息可以是用于确定上述码本的配置的相关信息,另外,上述码本信息可以通过如下至少一种方式确定:
控制节点配置、协议预定义、其他终端指示、终端间协商和预配置。
例如:上述码本信息包括码本对应的大小、结构和位置信息时,这多项可以通过一种或者多种方式确定,如码本对应的大小由控制节点配置,码本对应的结构由协议预定义,码本对应的位置信息预配置。
而上述sidelink信息可以是sidelink传输的相关信息。例如:上述sidelink信息可以包括如下至少一项:
sidelink HARQ-ACK、sidelink SR和sidelink CSI。
本公开实施例中,HARQ-ACK信息包含一个或者多个状态比特,每个状态比特指示NACK或者ACK。
需要说明的是,本公开实施例中主要以sidelink信息为sidelink HARQ-ACK进行举例说明,而sidelink SR和sidelink CSI可以参见sidelink HARQ-ACK的相应说明,在本公开实施例中不作赘述。
上述依据码本信息,获取sidelink信息对应的码本可以是,依据码本信息,生成或者确定sidelink信息对应的码本。且上述码本中可以包含针对多个传输的Sidelink信息。
另外,上述终端可以是sidelink传输的接收终端(RX UE)或者发送终端(TX UE),也就是说,上述sidelink信息可以包括:
接收用户反馈的sidelink信息;或者
依据接收sidelink传输的接收情况确定的sidelink信息。
例如:在一种情况下,TX UE发送sidelink传输,RX UE接收sidelink传输并确定对应的sidelink HARQ-ACK,RX UE通过物理旁链路反馈信道(Physical Sidelink Feedback Channel,PSFCH)或者物理旁链路共享信道(Physical Sidelink Shared Channel,PSSCH)将sidelink HARQ-ACK反馈给TX UE,TX UE接收对应至少一个sidelink传输的sidelink HARQ-ACK或者接收来自至少一个RX UE的sidelink HARQ-ACK,这些信息为sidelink信息,并由TX UE发送sidelink信息对应的码本。
在另一种情况下,RX UE接收至少一个sidelink传输并确定对应的 sidelink HARQ-ACK,这些信息为sidelink信息,并由RX UE发送sidelink信息对应的码本。
步骤202、发送所述码本。
上述发送码本可以是向控制节点发送码本,也可以是向其他终端发送码本信息,再由其他终端转发给控制节点。另外,发送码本可以是通过PUCCH、PUSCH、PSFCH或者PSSCH发送,具体对此不作限定。
本公开实施例中,码本可以是在目标资源上发送,且不同码本可以在不同目标资源上发送,当然,对此不作限定,例如:同一目标资源上可以发送多个码本,如多个码本复用在同一个目标资源上。需要说明的是,本公开实施例中目标资源可以是指发送码本的资源,且目标资源上可以将码本与其他信息复用发送。
例如:终端发送sidelink信息的目标资源和终端发送对应Uu链路传输的HARQ-ACK信息的目标资源(例如,上行资源PUCCH或PUSCH)重叠时,终端将sidelink信息和对应Uu链路传输的HARQ-ACK信息复用,通过目标资源发送给基站;或者,当终端发送sidelink信息(该sidelink信息可以称作第一sidelink信息)的目标资源,该终端和sidelink控制节点之间传输对应的sidelink信息(该sidelink信息可以称作第二sidelink信息)的目标资源(例如,sidelink资源PSFCH或者PSSCH)重叠时,该终端将第一sidelink信息和第二sidelink信息进行复用,通过目标资源发送给sidelink控制节点。
例如:如图3所示,终端1在Uu时隙(slot)n接收到下行控制信息(Downlink Control Information,DCI)1和DCI2,其中,DCI1调度终端1在Sidelink时隙m传输SCI1和PSSCH1,DCI2调度终端1在Sidelink时隙m+1传输SCI2和PSSCH2,且SCI1和PSSCH1对应的PSFCH1,以及SCI2和PSSCH2对应的PSFCH2在Sidelink时隙m+2重叠,接收这两个sidelink传输(SCI+PSSCH)的用户可以分别在PSFCH1和PSFCH2上反馈对应这两个传输的sidelink HARQ-ACK信息。并且,这两个传输对应的sidelink HARQ-ACK信息可以在同一物理上行链路控制信道(Physical Uplink Control Channel,PUCCH)进行复用,即发送终端1在PSFCH1和PSFCH2获取sidelink HARQ-ACK信息并在PUCCH上发送对应的码本。其中,PSFCH3可以是空闲的 PSFCH。
需要说明的是,本公开实施例中,sidelink传输可以是发送或者接收,另外,sidelink传输可以是传输旁链路控制信息(Sidelink Control Information,SCI)和数据中的至少一项。
本公开实施例中,通过上述发送sidelink信息对应的码本,从而使得不同侧之间对sidelink信息理解一致,使得控制节点可以正常调度终端传输,以满足sidelink传输时延等方面的要求,进而提高资源利用率。另外,由于发送的是sidelink信息对应的码本,从而可以降低终端向控制节点发送的sidelink信息大小(size)较大时所需的资源,同时也可以降低控制节点调度对其他链路的影响。
作为一种可选的实施方式,上述码本信息包括如下至少一项信息:
所述码本对应的位置的类型;
所述码本对应的位置;
所述码本的结构;
所述码本对应的位置的遍历信息;
所述码本的大小;
其中,所述位置包括时机(occasion)和频域位置中至少一项。
本公开实施例中,一个位置可以对应sidelink信息中的一个或者多个比特(bit),且不同位置对应的bit数量可以相同或者不同。而步骤201中的sidelink信息可以是上述码本对应的位置的sidelink信息的集合。另外,一个目标资源(或者说对于该目标资源上传输的码本)至少一个有对应的位置。
另外,一个occasion在码本中可以对应一个或者多个的HARQ-ACK比特。
上述码本对应的位置的类型可以是用于确定上述码本对应哪些类型的位置,例如:occasion。
上述码本对应的位置可以是,位置和码本的对应关系,终端通过该对应关系推出一个目标资源上的码本对应哪些位置,例如:occasion。
上述码本的结构可以是一个码本,或者由至少两个子码本组成。
上述码本对应的位置的遍历信息可以用于配置如何进行配置的遍历,即 如何对位置进行排序,从而确定码本中bit和位置的顺序对应关系。
上述码本的大小可以是码本中包含的sidelink信息的bit数大小。例如:获取码本对应的occasion,以及每个occasion对应的sidelink信息(例如:HARQ-ACK)bit数大小后,可以确定码本的大小。另外,一个码本中可以是很多个sidelink传输对应的HARQ-ACK信息的级联。
该实施方式中,由于上述码本信息包括上述至少一项,从而可以依据该码本信息准确地确定上述sidelink信息的码本。需要说明的是,当上述码本信息只包括上述多项中的部分时,未被上述码本信息包括的部分可以协议定义或者预配置等,对此不作限定。
需要说明的是,本公开实施例中,主要以位置为occasion进行举例说明。

进一步的,终端可以确定该目标资源和位于时间n-K6且实际收到了调度信令的occasion存在对应关系。
之后,终端针对确定的每个调度信令occasion,终端确定该occasion对应的HARQ-ACK信息,例如:终端根据occaison的配置确定occasion对应的HARQ-ACK信息。终端级联不同occasion对应的HARQ-ACK信息得到码本,并在对应的目标资源上将码本进行发送,如发给控制节点。
其中,上述sidelink传输可以包含发送或接收,另外,同一个终端在某些时刻可能在发送,在其他时刻可能在接收。且上述sidelink传输的位置可以包括如下至少一项:

进一步,终端可以确定该目标资源和位于时间n-K8且实际发送了或者收到了sidelink信息的occasion(或者sidelink信息反馈资源的occasion)存在对应关系。
之后,针对确定的每个sidelink信息的occasion(或者sidelink信息反馈资源的occasion),用户确定该occasion对应的HARQ-ACK信息,例如:终端根据occasion的配置确定occasion对应的HARQ-ACK信息。终端级联不同occasion对应的HARQ-ACK信息得到码本,并在对应的目标资源上将码本进行发送,如发送给控制节点。

另外,上述条件可以是在反馈机制为机制2的情况下实现的,例如:组播情况下采用机制2。
下面,如果某个occasion对应的传输方式为组播,有M个接收终端,且采用机制2反馈进行举例说明:
一、如果用户在某个载波/bwp/resource pool对应的传输方式为:一个PSSCH上传输1个TB,则该载波/bwp/resource pool上的该occasion对应码本中1*M bit HARQ-ACK。
二、如果用户在某个载波/bwp/resource pool对应的传输方式为:一个PSSCH上传输2个TB:
如果这两个TB对应的HARQ-ACK信息进行复用,则该载波/bwp/resource pool上的该occasion对应码本中1*M bit HARQ-ACK,或者,所有载波/所有bwp/所有resource pool上的该occasion分别对应码本中1*M bit HARQ-ACK,例如:有4个载波,对于occasion m,每个载波在occasion m都分别对应码本中的1*M bit;
如果这两个TB对应的HARQ-ACK信息不进行复用,则该载波/bwp/resource pool上的该occasion对应码本中2*M bit HARQ-ACK,进一步的,该情况下的HARQ-ACK信息对应一个单独的子码本或者单独的码本;
或者,如果这两个TB对应的HARQ-ACK信息不进行复用,则所有载波/所有bwp/所有resource pool上的该occasion分别对应码本中2*M bit HARQ-ACK,例如有4个载波,对于occasion m,每个载波在occasion m都分别对应码本中的2*M bit。
三、如果用户在某个载波/bwp/resource pool对应的传输方式为:一个PSSCH上传输CBG:
如果传输的是1个TB的CBG,则该载波/bwp/resource pool上的该occasion对应码本中CBG_NUM_MAX*M bit HARQ-ACK,或者,所有载波/所有bwp/所有resource pool上的该occasion分别对应码本中CBG_NUM_MAX*M bit HARQ-ACK,例如:有4个载波,对于occasion m, 每个载波在occasion m都分别对应码本中的CBG_NUM_MAX*M bit;

进一步的,本公开实施例中,上述组播的HARQ-ACK码本可以为一个单独的子码本或者单独的码本。
需要说明的是,上述组播的HARQ-ACK码本可以为一个单独的子码本或者单独的码本。
另外,上述所有载波/所有bwp指的是该终端被配置的所有载波/所有bwp,所有resource pool指的是和该resource pool(即上述描述的某个resource pool,例如:在上述资源为resource pool,则该resource pool可以为上述第一资源至第八资源的resource pool)属于相同bwp/载波/载波组的所有resource pool。
另外,本公开实施例中,终端可以将多个sidelink传输的HARQ-ACK信息进行求与运算,得到的结果作为码本中这些传输对应的HARQ-ACK比特。所述多个sidelink传输可能是同一个维度上的sidelink传输,维度可能包含连接、业务、HARQ进程、载波、带宽部分BWP、资源池、子信道、sidelink信息反馈资源、用户、传输类型、资源调度类型、传输方式、时延、比值、位置和资中的至少一种。例如对同一个资源池上的多个sidelink传输的HARQ-ACK信息进行求与运算。
例如,终端可以将对应同一个目标资源的多个sidelink传输(无论调度类型,传输类型,传输方式等)的HARQ-ACK信息进行求与运算,得到的结果作为码本中这些sidelink传输对应的HARQ-ACK比特;更具体地,目标资源和4个sidelink传输对应,4个传输中两个是调度信令进行动态调度的sidelink传输,另外两个是configured sidelink grant上的sidelink传输,每个传输分别有1bit的HARQ-ACK信息,指示的状态为NACK,NACK,ACK,ACK(假设0表示NACK,1表示ACK,则对应数值为0,0,1,1),用户对着这些bit求与,得到的结果为1bit的0,即NACK,从而码本中1bit对应这4 个传输,且该bit指示NACK.又例如目标资源和4个sidelink传输对应,4个传输中两个是单播,另外两个是组播,每个传输分别有1bit的HARQ-ACK信息,指示的状态为NACK、NACK、ACK、ACK(假设0表示NACK,1表示ACK,则对应数值为0,0,1,1),用户对着这些bit求与,得到的结果为1bit的0,即NACK,从而码本中1bit对应这4个传输,且该bit指示NACK。
终端可以将来自不同终端反馈的HARQ-ACK信息进行求与运算,得到的结果作为码本中这些传输对应的HARQ-ACK比特;例如对于组播,终端可以将所有RX UE反馈的HARQ-ACK信息进行求与运算,得到的结果作为码本中该组播传输对应的HARQ-ACK比特;例如TX UE发送一个组播传输,有4个RX UE且反馈的HARQ-ACK信息为NACK、NACK、ACK、ACK(假设0表示NACK,1表示ACK,则对应数值为0,0,1,1),TX UE对着这些bit求与,得到的结果为1bit的0,即NACK,从而码本中1bit对应这个组播传输,且该bit指示NACK。
对于对应相同目标资源的至少两个传输,终端可以将对应的HARQ-ACK求与运算,得到的结果作为码本中这些传输对应的HARQ-ACK比特;
上述至少两个传输可以是configured sidelink grant上的传输和动态调度;或者上述至少两个传输可以是组播传输和单播传输。
另外,可选地对于采用反馈机制1情况,对应目标资源的occasion的sidelink信息指示为NACK或者不连续发送(Discontinuous Transmission,DTX)时,对应的码本该occasion对应的HARQ-ACK比特的并不一定指示NACK或者DTX,TX UE可以自己判断反馈的内容。
一个occasion在码本中可能对应一个或者多个HARQ-ACK比特。
本公开实施例中,依据码本信息,获取sidelink信息对应的码本;发送所述码本。由于发送sidelink信息对应的码本,从而使得不同侧之间对sidelink信息理解一致,使得控制节点可以正常调度终端传输,以满足sidelink传输时延等方面的要求,进而提高资源利用率。
