具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
根据相关技术中的协议,模式1(Mode 1)下的HARQ反馈具体包括:第一终端通过上行链路uplink反馈给网络侧设备。如图1所示,具体步骤如下:
步骤1,第二终端发送上行调度请求SR以及直通链路缓存状态报告BSR给网络侧设备;
步骤2,网络侧设备发送直通链路调度(sidelink grant)给第二终端进行资源分配;
步骤3,第二终端根据收到的网络侧设备发送的sidelink grant,在相应的资源发送直通链路控制信息SCI和数据(data)。
步骤4,第一终端盲检SCI,接收数据,并发送直通链路反馈控制信息(包括ACK或NACK或DTX)给网络侧设备;
步骤5,网络侧设备发送sidelink grant给第二终端调度重传。
上述HARQ反馈方式中直通链路反馈控制信息通过Uu口反馈,可靠性高,且节省了第二终端向网络侧设备申请资源的步骤,时延低。但是上述HARQ反馈方式存在以下问题:
第一终端反馈直通链路反馈控制信息给基站的资源分配问题,以及,第二终端收到调度重传的sidelink grant时,如何辨别其对应的是那个HARQ进程的问题。
如图2所示,本公开实施例提供一种信息传输方法,应用于第一终端,包括:
步骤21,接收第二终端发送的直通链路数据(sidelink data),基于所述直 通链路数据生成直通链路反馈控制信息;
步骤22,在第一上行链路资源上发送所述直通链路反馈控制信息。
需要说明的是,本公开实施例中,第一终端为直通链路的接收终端,第二终端为直通链路的发送终端。
可选的,上述第一上行链路资源可以是物理上行控制信道(Physical uplink control channel,PUCCH)资源,也可以是物理上行共享信道(Physical Uplink Shared CHannel,PUSCH)资源。
可选的,本公开的上述实施例中,所述方法还包括:

PUSCH资源信息,用于指示所述直通链路反馈控制信息在所占用的时隙内使用的起始符号、符号长度、起始物理资源块(Physical Resource block,PRB)以及PRB数量。
具体根据上述信息中的哪一个或哪几个来确定第一上行链路资源可通过协议规定的方式确定。
作为一个可选实施例(显式指示),所述根据下述信息中的至少一个,确定所述直通链路反馈控制信息占用的第一上行链路资源,包括:

接收网络侧设备发送的物理层下行控制信令,所述物理层下行控制信令用于指示所述高层信令配置或协议约定的可用值集合中的一个可用值;
根据所述物理层下行控制信令指示的可用值,确定所述直通链路反馈控制信息占用的第一上行链路资源。
需要说明的是,本公开的上述实施例中,网络侧设备发送的物理层下行 控制信令可以是网络侧设备直接发送给第一设备的,也可以是网络侧设备发送给第一设备和第二设备的。
若物理层下行控制信令是网络侧设备直接发送给第一设备,则该下行控制信令中可以仅携带指示可用值的指示域即可;若物理层下行控制信令是网络侧设备发送给第一设备和第二设备的,则该下行控制信令中不仅需携带指示可用值的指示域,还需携带其指示域适用的第一终端的标识等,在此不一一枚举。
作为一个可选实施例(显式指示),所述根据下述信息中的至少一个,确定所述直通链路反馈控制信息占用的第一上行链路资源,包括:

根据接收SCI的资源和/或接收直通链路数据的资源,确定至少一个信息的可用值,并根据确定的可用值确定所述第一上行链路资源。
需要说明的是,接收SCI的资源和/或接收直通链路数据的资源与至少一个信息的可用值之间具有一定的映射关系,第一终端根据接收SCI的资源和/或接收直通链路数据的资源就可以确定至少一个信息的可用值。
作为又一个可选实施例(显式指示+隐式指示),所述根据下述信息中的至少一个,确定所述直通链路反馈控制信息占用的第一上行链路资源,包括:

例如,网络侧设备通过高层信令配置第一终端发送直通链路反馈控制信息在上行资源上传输的时隙信息m的可用值集合为m∈{1,2,3,4,5,6,7,8};其表示若第一终端在时隙n接收到直通链路数据,则第一终端是时隙n+m向网络侧设备发送直通链路反馈控制信息。
网络侧设备通过高层信令配置第一终端反馈直通链路反馈控制信息的PUCCH资源信息,其用于指示上行控制信息可占用的PUCCH资源ID。例如,PUCCH资源信息{0,1,2,3,4,5,6,7}分别代表高层配置的PUCCH资源列表中的第1,2,3,4,5,6,7或8个PUCCH资源。
网络侧设备向第二终端发送物理层下行控制信令,用3比特(例如001)指示时隙信息m为1,用另外3比特(例如000)指示PUCCH资源ID为PUCCH资源0;
第二终端根据接收到的物理层下行控制信令,将时隙信息和PUCCH资源ID的相关信息填充至SCI中,并转发给第一终端。
第一终端在时隙n接收到直通链路数据,根据接收到的高层配置和SCI指示,则第一终端在时隙n+1的PUCCH资源0上发送所述直通链路反馈控制信息给网络侧设备。
进一步的,本公开的上述实施例中,步骤21之前,所述方法还包括:
接收所述第二终端发送的SCI,所述SCI为所述直通链路数据的调度控制信息,所述SCI包括下述至少之一:
