在该种情况下,可选的,网络设备可以通过资源调度的方式为终端设备分配资源。或者,网络设备可以为多个终端设备分配一个资源池,由多个终端设备通过竞争的方式在资源池中获取资源。其中,网络设备可以为控制信息和数据信息分配相互独立的资源池,也可以为控制信息和数据信息分配共享的资源池。需要说明的是,本申请所涉及的控制信息可以为侧行链路(sidelink)的控制信息,本申请所示的数据信息可以为侧行链路的数据信息。为了便于描述,在下述实施例中不再进行赘述。具体的,参见如下两种可行的实现方式:
一种可行的实现方式:控制信息和数据信息的资源池相互独立
下面,结合图1,对用于发送控制信息的控制资源池和用于发送数据信息的数据资源池进行详细说明。
图1为本申请提供的一种资源池的示意图。请参见图1,网络设备为终端设备分配数据资源池A和控制资源池B。数据资源池A中的资源仅用于终端设备发送数据信息,控制资源池中的资源仅用于终端设备发送控制信息。数据资源池A和控制资源池B相互独立。

另一种可行的实现方式:控制信息和数据信息共享资源池
下面,结合图2,对用于发送控制信息和数据信息的共享资源池进行详细说明。
图2为本申请提供的另一种资源池的示意图。请参见图2,网络设备为终端设备分配共享资源池C,共享资源池C中的资源用于终端设备发送数据信息和控制信息。
多个终端设备均可以通过共享资源池C中的资源发送数据信息和控制信息。例如,UE1可以通过资源池中的资源C1发送数据信息,UE1可以通过资源池中的资源C2发送控制信息。例如,UE2可以通过资源池中的资源C3发送数据信息,UE3可以通过资源池中的资源C4发送控制信息。
需要说明的是,本申请所示的共享资源池是指既可以发送数据信息又可以发送控制信息的资源的集合,当然,既可以发送数据信息又可以发送控制信息的资源的集合还可以有其它的称呼,例如,还可以称为单播资源池、组播资源池、广播资源池等。
第二种:终端设备位于网络设备的网络覆盖范围之外
在该种情况下,可选的,终端设备可以在预定义的带宽中通过竞争的方式获取资源。
例如,预定义的带宽可以为专用载波带宽,或专用载波上的部分带宽。
为了便于对本申请的理解,下面,结合图3介绍一种可适用于本申请所示技术方案的系统架构图。

其中,两个终端设备之间可以相互通信。一般地,终端设备之间的直联链路称为侧行链路(sidelink)。
可选的,一个终端设备可以确定用于发送控制信息的第一资源集合,并向与其通信的其它终端设备发送用于指示第一资源集合的第一信息。这样,其它终端设备在盲检测该终端设备发送的控制信息时,只需要在第一资源集合的资源中进行检测即可,进而缩小终端设备盲检测的范围,减少了终端设备盲检测的复杂度,节省了终端设备的功耗。
可选的,图3所示的应用系统架构可应用于车联网系统,在图3所示实施例的基础上,下面,通过图4所示的实施例,对车联网系统的架构进行介绍。
图4为本申请提供的车联网系统的架构示意图。请参见图4,包括第一车辆401、第二车辆402、行人403和网络设备404。

下面,通过具体实施例对本申请所示的技术方案进行详细说明。需要说明的是,下面几个具体实施例可以单独存在,也可以相互结合,对于相同或相似的内容,在不同的实施例中不再进行重复说明。
图5为本申请提供的一种控制信息传输方法的流程示意图。其中,第一设备和第二设备为可进行侧行链路通信的终端设备。请参见图5,该方法可以包括:
S501、第一设备确定第一资源集合。
其中,第一资源集合为第一设备发送控制信息所使用的资源的集合。
第一资源集合包括时域资源、频域资源、码域资源、空域资源、功率域资源中的至少一项。第一资源集合中的资源可以包括频域资源,如资源块RB的索引、RB的数量、子信道索引、子信道中的RB的标识。第一资源集合中的资源可以包括时域资源,如符号位置(包括起始符号或终止符号)、符号数量、时隙位置(包括起始时隙或终止时隙)、时隙数量等。第一资源集合可以包括码域资源,如根序列、掩码、扰码、循环移位、梳齿等。第一资源集合可以包括空域资源,如码字、流、层、天线数、天线端口编号、天线端口数等。第一资源集合可以包括功率域资源,如功率值、功率范围、功率偏移、功率门限等。
可选的,第一设备可以在第二资源集合中确定第一资源集合,第二资源集合中的资源用于发送侧行链路的控制信息,第一资源集合是第二资源集合的子集。
可选的,第一资源集合可以为第二资源集合的真子集。即,第一资源集合为第二资源集合中的一部分。
可选的,第二资源集合为用于发送侧行链路控制信息的资源的集合;或者,第二资源集合为第三资源集合中用于发送侧行链路控制信息的资源的集合,所述第三资源集合为用于发送侧行链路控制信息和数据信息的资源的集合。
例如,第二资源集合可以是PSCCH资源池,也可以是PSCCH与PSSCH共享的资源池,或者是PSCCH与PSSCH共享的资源池中可用于PSCCH传输的资源。
换句话说,第一资源集合是PSCCH资源池的子集。
可选的,第一资源集合中的资源可以为第一设备在第二资源集合中确定得到的、第一设备的可用资源(available resources),其中,可用资源为发送终端通过检测能量或解码其他用户的PSCCH,排除掉其他用户占用的资源之后,得到的资源集合。
可选的,第一资源集合可以包括至少一个子信道和/或所述至少一个子信道中的部分资源。
例如,若用于承载物理侧行控制信道(Physical Sidelink Control Channel,PSCCH)的子信道位于控制信息资源池或共享资源池中的专用区域(专用区域是指共享资源池中仅用于发送控制信息的区域),则该子信道仅用于承载PSCCH。在该种情况下,第一资源集合中包括至少一个子信道。
例如,若子信道只有部分资源用于承载PSCCH,则第一资源集合可以包括至少一个子信道中的部分资源。例如,若共享资源池中3个子信道用于承载PSCCH,且该3个子信道 中的低频2个RB用于承载PSCCH,其余资源用于发送物理侧行共享信道(Physical Sidelink Shared Channel,PSSCH),则确定第一资源集合中包括该3个子信道中的部分资源。
例如,若用于承载PSCCH的子信道均位于共享资源池中,且一部分用于承载PSCCH的子信道中只有部分资源用于承载PSCCH,另一部分用于承载PSCCH的子信道中的所有资源用于承载PSCCH,则第一资源集合可以包括至少一个子信道和至少一个子信道中的部分资源。例如,若共享资源池中的子信道1和子信道2中的资源均用于承载PSCCH,子信道3和子信道4中的低频2个RB用于承载PSCCH,则确定第一资源集合中包括子信道1、子信道2、子信道3中的低频2个RB和子信道4中的低频2个RB。
可选的,第二资源集合可以为网络设备为终端设备分配的、控制信息资源池中的资源集合。例如,第二资源集合可以为图1中的资源池B。
可选的,第二资源集合可以为网络设备为终端设备分配的、共享资源池中用于传输控制信息的资源的集合,共享资源池中的资源用于传输控制信息和数据信息。例如,第二资源集合可以为图2中的资源池C。
可选的,第二资源集合还可以为预定义的、用于传输控制信息的资源集合。
可选的,第一设备可以通过至少如下三种可行的实现方式确定第一资源集合:
一种可行的实现方式:
第一设备在第二资源集合中的资源上进行能量检测,并根据检测到的能量确定第一资源集合。
其中,若第一设备在第二资源集合中的一个资源上检测到的能量较低,说明第一设备在使用该资源时,与已使用该资源的其他设备之间的干扰较小。
可选的,第一设备可以检测第二资源集合中M个资源上的能量,若在一个资源上检测到的能量小于第一阈值,则可以将该资源确定为第一资源集合中的资源。即,第一设备在第一资源集合中的资源上检测到的能量小于第一阈值。在实际应用过程中,可以根据实际需要设置该第一阈值。
可选的,第一设备还可以检测第二资源集合中M个资源上的能量,并对在M个资源上检测到的能量进行排序,将检测到的能量最小的N个资源确定为第一资源集合中的资源,N为大于1的整数。在实际应用过程中,可以根据实际需要设置N的大小。
在该种可行的实现方式中,由于第一资源集合中的资源为第一设备检测到的能量较低的资源,这样,在第一设备在第一资源集合中的资源上发送控制信息时,第一设备对已经使用第一资源集合中的资源的其它设备的干扰较小。在能量较低的资源上发送,第一设备受到其他设备的干扰也较小,进而使得第一设备可以在第一资源上传输的控制信息的信噪比较大。
另一种可行的实现方式:
第一设备对第二资源集合中的资源上发送的控制信息进行检测,以确定第一资源集合。
可选的,若第一设备在第二资源集合中的一个资源上未检测到其它设备发送的控制信息,则可以将该资源确定为第一资源集合中的资源。即,第一设备在第一资源集合中的资源上未检测到控制信息。
在该种可行的实现方式中,由于在第一资源集合中的资源上未传输其它控制信息,因此,在第一设备在第一资源集合中的资源上发送控制信息时,第一设备对已经使用第一资 源集合中的资源的其它设备的干扰较小。在未检测到其它设备发送控制信息的资源上发送,第一设备受到其他设备的干扰也较小,进而使得第一设备可以在第一资源上传输的控制信息的信噪比较大。
再一种可行的实现方式:
第一设备接收第三设备发送的至少一个资源集合,第一设备在该至少一个资源集合中确定第一资源集合。
或者第三设备只向第一设备发送一个资源集合,第一设备将该一个资源集合确定为第一资源集合。
可选的,第三设备可以向第一设备发送多个资源集合中的资源的标识。第三设备还可以向第一设备发送多个资源集合的标识。第三设备还可以向其它设备发送至少一个资源集合和多个资源集合的标识。例如,第三设备可以广播、组播或者单播该至少一个资源集合和多个资源集合的标识。
例如,资源集合的标识和资源集合的对应关系可以如表1所示:
表1
资源集合的标识 资源集合
00 子信道1、子信道2
01 子信道2、子信道3
10 子信道6、子信道7中的RB1和RB2
可选的,第三设备可以为基站或者同步源。例如,当第一设备位于基站的网络覆盖范围之内时,则第三设备可以为基站。当第一设备不位于基站的网络覆盖范围之内时,则第三设备可以为同步源或组头。同步源为向其它设备发送同步信号的设备,同步信号可以用于进行时钟同步等。组头可以为其他设备分配资源,管理组员的加入和离开等。对于车队场景,车队的组头可以位于车队的任何位置,优选车队的中间位置,也可以是车队最前面的第一辆车(头车),或者是车队最后面的一辆车(尾车),或者是一般意义中的组头(Group header)。
可选的,本申请所涉及的同步源为第一设备同步到的同步源。
可选的,第三设备可以通过广播消息MIB、系统消息SIB、RRC信令、MAC层信令、物理层信令DCI等向第一设备发送至少一个资源集合。
若第三设备是一个终端设备,第三设备可以通过PSBCH、PSCCH、PSSCH、RRC信令、MAC层信令等向第一设备发送至少一个资源集合。
可选的,第一设备可以将至少一个资源集合中的一个资源集合确定为第一资源集合。或者,第一设备可以对M个资源集合中的资源的能量进行检测,以在至少一个资源集合中确定第一资源集合,例如,第一设备可以将至少一个资源集合中、检测到的能量最低的一个资源集合确定为第一资源集合。
第三设备为第一设备确定的至少一个资源集合中的M个资源均为第一设备的可用资源。
需要说明的是,第三设备可以为多个设备确定至少一个资源集合,第三设备为不同的设备确定的至少一个资源集合可能不同。
在该种可行的实现方式中,由第三设备为第一设备确定至少一个资源集合,使得第一 设备只需在至少一个资源集合中选择一个资源集合作为第一资源集合即可,进而使得第一设备可以快速确定第一资源集合。
第一设备只在第一资源集合内发送PSCCH,而不会在第一资源集合外发送PSCCH,并且第一设备向第二设备发送指示第一资源集合,这样,第二设备可以在第一资源集合中盲检测第一设备发送的控制信息,缩小了第二设备的盲检测范围,减少了终端设备盲检测的复杂度,节省了终端设备的功耗。
S502、第一设备向第二设备发送第一信息,第一信息用于指示第一资源集合。相应的,第二设备接收第一信息。
其中,第二设备为可以与第一设备通信的一个或多个设备。
可选的,第一信息包括第一资源集合中的资源的标识、第一资源集合的标识、时间范围、有效次数中的至少一种。
需要说明的是,第一信息还可以包括其它,本申请对此不作具体限定。
第一资源集合包括时域资源、频域资源、码域资源、空域资源、功率域资源中的至少一项。
可选的,第一资源集合中的资源可以包括频域资源,如资源块RB的索引、RB的数量、子信道索引、子信道中的RB的标识。第一资源集合中的资源可以包括时域资源,如符号位置(包括起始符号或终止符号)、符号数量、时隙位置(包括起始时隙或终止时隙)、时隙数量等。第一资源集合可以包括码域资源,如根序列、掩码、扰码、循环移位、梳齿等。第一资源集合可以包括空域资源,如码字、流、层、天线数、天线端口编号、天线端口数等。第一资源集合可以包括功率域资源,如功率值、功率范围、功率偏移、功率门限等。

例如,假设有效次数为5次,则在第一设备发送第一信息之后,第一设备前5次发送控制信息时,第一设备在第一资源集合的资源中发送控制信息,在第一设备第6次或者之后发送控制信息时,第一设备不一定在第一资源集合的资源中发送控制信息。

可选的,第一信令可以承载在PSCCH、PSSCH、物理侧行广播信道(Physical Sidelink Broadcast Channel,PSBCH)中的一种信道中。
若第一信令为PSCCH或PSSCH,则第一信令中包括的第一信息指示的第一资源集合为下一次或者之后一段时间或次数内用于发送PSCCH的资源。
可选的,第一信令可以为RRC信令或同步信号中的一种。
需要说明的是,当第二设备为一个设备时,则第一设备可以通过单播的方式向第二设备发送第一信息。当第二设备为多个设备、且第二设备为第一设备的组内设备时,则第一设备可以通过组播的方式向第二设备发送第一信息。当第二设备为不限制数量个设备、且第二设备为可与第一设备通信的设备时,则第一设备可以通过广播的方式向第二设备发送第一信息。
S503、第一设备在第一资源集合中的资源上,向第二设备发送控制信息。
需要说明的是,在S502之后,第一设备无需立刻执行S503。即,在第一设备执行S502之后,只有当第一设备需要向第二设备发送控制信息时才执行S503。
可选的,在S502之后,第一设备可以在第一资源集合中向第二设备发送一个或多个控制信息。
例如,第一信息包括时间范围,假设第一信息包括的时间范围为时刻1-时刻2,则在第一设备向第二设备发送第一信息之后,第一设备在时刻1-时刻2之间,第一设备可以在第一资源集合中的资源上向第二设备发送多个控制信息,且第二设备均在第一资源集合中检测该多个控制信息。
例如,第一信息包括有效次数,假设第一信息包括的有效次数为5次,则在第一设备向第二设备发送过第一信息之后,第一设备可以在第一资源集合中的资源上向第二设备发送5次控制信息,且第二设备均在第一资源集合中检测该5次发送的控制信息。
例如,假设第一信息中不包括时间范围和有效次数,则在第一设备向第二设备发送过第一信息之后、第一设备发送第一信息对应的失效信息之前,第一设备均可以在第一资源集合中的资源上向第二设备发送控制信息,且第二设备在第一资源集合中检测控制信息。
