Description

信息传输方法、装置及存储介质 技术领域
本申请实施例涉及通信技术领域，尤其涉及一种信息传输方法、装置及存储介质。

然而，由于终端通常采用最大发送功率发送反馈信息，同一通信组内的多个接收终端发送的反馈信息同时到达发送终端时，距离发送终端较近的接收终端的反馈信息可能会覆盖距离发送终端较远的接收终端的反馈信息，导致发送终端检测不到较远的接收终端的反馈信息，存在检测反馈信息失败的问题。

为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。

随着网络技术及智能车辆技术的发展，车联网越来越受到广泛关注。车联网系统是基于D2D的一种侧行链路传输技术，其与传统的LTE系统中通信数据通过基站接收或者发送的方式不同，车联网系统采用终端到终端直接通信的方式，具有更高的频谱效率以及更低的传输时延。
在第三代合作伙伴计划(3rd generation partnership project，3GPP)中，D2D分成了不同的阶段进行研究，如下：
邻近服务(proximity based services，ProSe)：主要用来提高频谱利用率和降低基站负荷。具体的，终端通过基站分配的频谱资源进行直接通信，从而提高无线频谱资源的利用率，而终端间邻近业务成功建立后，可以执行设备到设备的通信，基站的负荷得以降低，其主要针对公共安全类的业务。
车联网(V2X)：车联网系统针对车车通信的场景进行了研究，其主要面向相对高速移动的车车、车人通信的业务。
可穿戴设备(FeD2D)：主要用于可穿戴设备通过移动终端接入网络的场景，其主要面向是低移动速度以及低功率接入的场景。
下面简要介绍一下V2X通信的架构示意图。
目前，在车联网通信系统中，车联网终端通过车用无线通信技术(vehicle-to-everything，V2X)实现车与X(车、人、交通路侧基础设施和网络)智能信息的交互。V2X通信的交互模式包括：车辆与车辆(vehicle to vehicle，V2V)之间、车辆与路边基础设施(vehicle to infrastructure，V2I)之间、车辆与行人(vehicle to pedestrian，V2P)之间、车辆与网络(vehicle to network，V2N)之间的通信。示例性的，路边基础设施可以是路边单元(road side unit，RSU)。
图1为V2X通信的架构示意图。如图1所示，V2X通信包括V2V通信、V2P通信、V2I通信和V2N通信，V2X通信过程中，V2X业务通过侧行链路(sidelink)或者Uu口进行传输。
在实际应用中，V2X借助与人、车、路、云平台之间的全方位连接和高效信息交互，实现信息服务、交通安全、交通效率等典型应用场景。车联网终端通过V2I和V2N通信可以获取各种信息服务，包括交通信号灯信息，附近区域车辆信息，车辆导航，紧急救援，信息娱乐服务等。通过V2V和V2P通信可以实时获取周围车辆的车速、位置、行车情况及行人活动等信息，并通过智能算法实现碰撞预警功能，避免交通事故。通过V2I通信可以实现车速引导等功能，提高交通效率。
随着技术的不断发展，目前引入新无线(new radio，NR)通信系统，NR系统中V2X称之为NR-V2X。下面对于NR-V2X的应用场景进行解释说明。
在NR-V2X系统中，需要支持自动驾驶，因此，对车载终端之间数据交互提出了更高的要求，如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
在NR-V2X系统中，通过侧行链路进行通信称之为V2X sidelink通信模式。该种通信模式下，车载终端可以工作在有网络覆盖的场景，或者没有网络覆盖的场景。
在有网络覆盖的场景中，V2X sidelink通信模式进一步的划分为集中调度传输模式和分布式传输模式。
在集中调度传输模式下，终端设备在侧行链路传输V2X业务的传输资源是由网络设备分配的，在NR-V2X系统中称为模式1，也称为mode1；在分布式传输模式下，网络设备配置V2X sidelink资源池，终端设备每次传输V2X业务时，在网络配置的资源池中获取资源，无需网络设备调度，该模式在NR-V2X系统中称为模式2，也称为mode2。详见图2和图3所示示意图的记载。
图2是模式1所适用的系统架构示意图。图3是模式2所适用的系统架构示意图。参照图2和图3所示，第一终端设备和第二终端设备是具备V2X通信能力的终端设备，用于执行V2X通信，第一终端设备与第二终端设备之间通过无线通信接口进行V2X通信，第一终端设备与网络设备，或者，第二终端设备与网络设备之间通过无线通信接口进行通信。为清楚起见，将第一终端设备和第二终端设备之间的无线通信接口称之为第一空口，该第一空口例如为sidelink，第一终端设备和网络设备之间或第二终端设备与网络设备之间的无线通信接口称之为第二空口，该第二空口例如为Uu口。
参照图2所示，作为一种示例，第一终端设备与第二终端设备的传输资源是由网络设备分配，第一终端设备与第二终端设备根据网络设备分配的资源在侧行链路上进行数据的发送；网络设备可以为第一终端设备与第二终端设备分配单次传输的资源，也可以为第一终端设备与第二终端设备分配半静态传输的资源，此处不再赘述。
参照图3所示，作为另一种示例，第一终端设备与第二终端设备可以在资源池中选取一个资源进行数据的传输。具体的，第一终端设备与第二终端设备可以通过侦听的方式在资源池中选取传输资源，或者通过随机选取的方式在资源池中选取传输资源，关于第一终端设备与第二终端设备选取传输资源的方式，其可以根据实际情况确定，此处不再赘述。
在没有网络覆盖的场景中，终端设备采用上述的模式2进行传输，这时，资源池是通过预配置的方式获取的。具体的传输方式同上述的模式2，这里不再赘述。
更进一步的，在NR-V2X中，为了提高传输可靠性，在侧行链路上引入了反馈信道，如图2和图3所示，第一终端设备(例如，UE1)与第二终端设备(例如，UE2)构成一个单播链路，UE1向UE2发送侧行数据，UE2根据接收到的侧行数据的检测结果，向UE1发送反馈信息。示例性的，该反馈信息可以是混合自动重传请求确认信息(hybrid automatic repeat request，HARQ ACK)或HARQ非确认信息(HARQ NACK)。
UE1根据接收到的UE2的反馈信息，决定是否重传向UE2发送的数据。
值得说明的是，终端设备之间的反馈信息同样适用于组播通信中，在一个通信组中，当一个终端发送组播信息时，该组内的其他终端根据接收数据的状态向发送方发送反馈信息。
示例性的，对于组播通信方式，反馈信息的内容可以包括如下两种方式：只反馈HARQ NACK、反馈HARQ ACK或者HARQ NACK。具体分析如下：
方式1：只反馈HARQ NACK。即，只有接收方终端(例如，UE2至UE4)距离发送方终端(例如，UE1)在一定距离范围内，并且没有正确接收物理侧行共享信道(physical sidelink shared channel，PSSCH)，即需要反馈HARQ NACK的接收方终端才发送反馈信息；进一步地，所有需要发送HARQ NACK的接收方终端使用相同的传输资源发送反馈信息。
方式2：反馈HARQ ACK或者HARQ NACK。通信组内的接收方终端，如果正确接收PSSCH就发送HARQ ACK，如果没有正确接收PSSCH就发送HARQ NACK，进一步地，不同的接收方终端使用不同的传输资源发送反馈信息，其中，不同的传输资源包括不同的时域资源、频域资源或者码域资源。
示例性的，图4为一个通信组中终端设备之间的信息传输示意图。图5为通信组中终端设备反馈信息的资源分布示意图。如图4所示，一个通信组包括4个终端设备(UE1至UE4)，当UE1发送侧行数据时，UE2、UE3、UE4是数据接收方，并且根据数据是否正确接收向发送方UE1发送反馈信息。
如图5所示，如果UE1在时隙n通过物理侧行控制信道(physical sidelink control channel，PSCCH)和物理侧行共享信道(physical sidelink shared channel，PSSCH)发送侧行数据，如果采用方式2，即每个接收方终端(UE2、UE3、UE4)都需要发送反馈信息HARQ ACK或者HARQ NACK，则在时隙n+1，UE2、UE3、UE4使用不同的传输资源通过物理侧行反馈信道(physical sidelink feedback channel，PSFCH)向UE1发送反馈信息。如果采用方式1，即只有需要发送HARQ NACK的终端(UE2或UE3或UE4)，并且在距离UE1一定距离范围内的终端才需要发送反馈信息。
本实施例中，假设UE2、UE3、UE4都在需要发送反馈信息的距离范围内，并且都没有正确接收PSSCH，即需要反馈HARQ NACK，则UE2、UE3、UE4使用相同的时频资源发送反馈信息，如时隙n+3所示。
对于反馈方式2，UE1需要分别检测每个终端(UE2、UE3、UE4)的反馈信息，判断哪些终端已经正确接收，哪些终端没有正确接收；对于反馈方式1，UE1只需要检测在反馈资源上是否存在用户反馈了NACK即可，不用区分哪些用户反馈。
对于反馈方式2，由于需要检测所有的反馈信息，因此，多个接收方终端之间的干扰应该尽量低，以保证检测性能。在侧行传输中，可能会存在远近效应问题，即离得近的用户的信号会覆盖离得远的用户的信号，从而导致检测不到离得远的用户反馈的信号。
示例性的，图6为远近效应的覆盖示意图，如图6所示，当UE2、UE3、UE4均采用最大发送功率发送反馈信息时，由于UE2离UE1距离近，UE4离UE1的距离远，因此，UE1检测到的UE2的信号能量高，检测到的UE4的信号能量低，UE2的信号造成的带外干扰的能量甚至会比UE1接收到的UE4的信号能量还要高，从而导致UE1检测UE4的反馈信息失败。
针对上述问题，本申请实施例提供了一种信息传输方法，通过在NR-V2X中引入了侧行功率控制，发送方终端(第二终端设备)向接收方终端(至少两个第一终端设备)发送的侧行数据信息中携带用于确定对该侧行数据信息进行反馈的反馈信息的目标发送功率，这样接收方终端可以基于该指示信息确定出反馈信息的目标发送功率，并以该目标发送功率向第二终端设备发送反馈信息，使得第二终端设备可以接收到每个第一终端设备发送的反馈信息，解决由于距离发送终端较近的接收终端的反馈信息可能会覆盖距离发送终端较远的接收终端的反馈信息而导致的检测反馈信息失败的问题。

示例性的，对于一个第一终端设备，该第一终端设备还可以通过解析接收到的侧行数据信息，检测该侧行数据信息的侧行参考信号接收功率，即侧行参考信号接收功率，进而根据该参考信号接收功率和获取到的指示信息共同确定反馈信息的目标发送功率。
例如，第一终端设备可以直接根据侧行参考信号接收功率、指示信息和第二终端的目标接收功率的关联关系，直接确定出反馈信息的目标接收功率，也可以首先根据侧行参考信号接收功率和指示信息包括的第一信息，确定出侧行链路的路损，再根据该侧行链路的路损和指示信息包括的第二信息，确定出反馈信息的目标发送功率。关于确定目标发送功率的具体实现方式可以根据实际情况确定，此处不再赘述。关于该步骤的具体实现原理可以参见下述图8所示实施例的记载，此处不再赘述。

值得说明的是，本申请实施例并不限定上述步骤的执行顺序，其可以根据实际情况确定。例如，第一终端设备先获取用于确定第二终端设备的目标接收功率的第二信息，再获取用于确定该第二终端设备的发送功率等。
本申请实施例提供的信息传输方法，第二终端设备向至少两个第一终端设备发送的侧行数据信息中携带有指示信息，该指示信息用于确定对该侧行数据信息进行反馈的反馈信息的目标发送功率，这样每个第一终端设备可以基于该指示信息确定出反馈信息的目标发送功率，并以该目标发送功率向第二终端设备发送反馈信息，也即，该技术方案使得各个第一终端设备发送的反馈信息到达第二终端设备的功率是相近的，从而避免由于距离发送终端较近的接收终端的反馈信息可能会覆盖距离发送终端较远的接收终端的反馈信息而导致的检测反馈信息失败的问题。
示例性的，在上述实施例的基础上，图8为本申请实施例提供的信息传输方法实施例二的交互示意 图。如图8所示，在本实施例中，对于每个第一终端设备，上述步骤73可以通过如下步骤实现：
步骤81：获取该侧行数据信息对应的侧行参考信号接收功率。
在本实施例中，每个第一终端设备可以根据侧行数据信息(例如，PSCCH或者PSSCH)，测量侧行数据信息中参考信号(reference signal，RS)的接收功率，从而确定出该侧行链路上的侧行参考信号接收功率(sidelink reference signal receiving power，SL-RSRP)。
步骤82：根据该侧行参考信号接收功率和指示信息，确定该反馈信息的目标发送功率。
示例性的，每个第一终端设备可以获取第一信息，例如，该指示信息中包括第一信息，根据该第一信息确定第二终端设备的发送功率；每个第一终端设备可以获取第二信息，例如，该指示信息中包括第二信息，根据该第二信息确定第二终端设备的目标接收功率。
作为一种示例，在本实施例中，第一终端设备可以根据确定出的第二终端设备的发送功率、目标接收功率和侧行参考信号接收功率SL-RSRP直接确定出目标发送功率。示例性的，在第一终端设备中预置有第二终端设备的发送功率、目标接收功率和侧行参考信号接收功率的关联关系时，第一终端设备便可以直接确定出反馈信息的目标发送功率。
作为另一种示例，该步骤82可以通过如下步骤实现：
A1：根据该侧行参考信号接收功率和第一信息，确定侧行链路的路损。
示例性的，在本实施例中，第一终端设备可以根据该第一信息，确定该第二终端设备的发送功率，进而根据该侧行信号接收功率和第二终端设备的发送功率，确定该侧行链路的路损。
具体的，第一终端设备可以根据获取到的侧行参考信号接收功率和第二终端设备的发送功率的量化功率信息确定该第二终端设备的发送功率，也可以根据获取到的侧行参考信号接收功率和第二终端设备的发送功率对应的功率等级标识确定该第二终端设备的发送功率，还可以根据侧行参考信号接收功率和第二终端设备的发送功率与第一功率的差值确定该第二终端设备的发送功率。关于具体的确定方法可以根据实际情况确认，此处不再赘述。
可选的，在本实施例中，第一终端设备还可以对侧行信号接收功率进行滤波处理，得到滤波后的侧行信号接收功率。
具体的，第一终端设备可以获取多个SL-RSRP，并对获取到的多个SL-RSRP进行滤波处理，相应的，第一终端设备可以根据滤波后的侧行信号接收功率和第二终端设备的发送功率，确定该侧行链路的路损，以提高测量的准确度。
A2：根据该侧行链路的路损和第二信息，确定反馈信息的目标发送功率。
在本申请的实施例中，该第一终端设备可以根据确定出的第二终端设备的发送功率和获取到的侧行参考信号接收功率估算出第二终端设备与第一终端设备之间的侧行链路的路损大小，再根据该侧行链路的路损和第二终端设备的目标接收功率确定出反馈信息的目标发送功率。
本申请实施例提供的信息传输方法，通过获取该侧行数据信息对应的侧行参考信号接收功率，根据该侧行参考信号接收功率和指示信息，确定该反馈信息的目标发送功率。该技术方案可以准确的确定出反馈信息的目标发送功率，使得达到第二终端设备的反馈信息的功率相近，避免了不同第一终端设备的反馈信息之间的覆盖问题。
示例性的，在上述实施例的基础上，图9为本申请实施例提供的信息传输方法实施例三的流程示意图。如图9所示，在本实施例中，对于每个第一终端设备，该信息传输方法还包括如下步骤：
步骤91：获取该第一终端设备的下行路损。
可选地，该步骤可以为步骤81之后，在获取到该侧行数据信息对应的侧行参考信号接收功率之后，若第一终端设备与第二终端设备之间的侧行链路传输和第一终端设备与网络设备之间的上行传输共享载波，则第一终端设备在确定反馈信息的目标发送功率时，需要考虑第一终端设备的侧行传输对其他终端上行传输的干扰，因而，在本实施例中，还需要获取该第一终端设备的下行路损。
具体的，在本实施例中，第一终端设备通过检测网络设备发送的下行数据信息，获取下行数据信息中参考信号RS的接收功率，从而确定出该下行参考信号接收功率，再获取网络设备发送该下行数据信息的发送功率，进而根据该下行参考信号接收功率和下行数据信息的发送功率确定出第一终端设备的下行路损。

可选的，在本实施例中，每个第一终端设备可以首先基于确定的下行路损，确定出一个发送功率，在本实施例中称为第一发送功率。
B2：根据该侧行参考信号接收功率和指示信息，确定第二发送功率。
可选的，该步骤可以通过上述图7和图8所示实施例的方法，每个第一终端设备利用侧行参考信号接收功率和指示信息，确定出可能的第二发送功率。
B3：根据该第一发送功率、第二发送功率和该第一终端设备的最大发送功率，确定该反馈信息的目标发送功率。
进一步的，由于第一终端设备的实际发送功率不能超出它的最大发送功率，所以，在本实施例中，当每个第一终端设备确定出第一发送功率、第二发送功率和该第一终端设备的最大发送功率后，可以从中确定一个最优的发送功率。具体的，为了避免对上行传输造成干扰，基于指示信息确定的反馈信息的目标发送功率不能超过按照下行路损确定的发送功率。需要说明的是，第一终端设备的最大发送功率可以是网络配置的终端设备的最大发送功率。
示例性的，首先确定出第一发送功率、第二发送功率和第一终端设备的最大发送功率中的最小发送功率，其次将该最小发送功率作为反馈信息的目标发送功率。
例如，若第一发送功率为P_dl，第二发送功率为P_sl，第一终端设备的最大发送功率为P_max，则该反馈信息的目标发送功率P_fb＝min(P_sl,P_dl,P_max)。
本申请实施例提供的信息传输方法，在确定第一终端设备的反馈信息的目标发送功率时，通过获取该第一终端设备的下行路损，再根据该下行路损、侧行参考信号接收功率和指示信息，确定该反馈信息的目标发送功率，其不仅可以解决现有技术存在的距离第二终端设备较远的第一终端设备反馈的反馈信息被检测失败的问题，而且可以避免为上行传输的干扰，提升了用户体验。
示例性的，在本申请的一种可能设计中，图10为本申请实施例提供的信息传输方法实施例四的流程示意图。该图10所示的实施例与上述图7至图9所示实施例的方法不同，图7至图9所示实施例主要是第一终端设备基于接收到的指示信息确定出用于反馈的反馈信息的目标发送功率，而图10所示的实施例主要是第一终端设备根据接收到的侧行数据信息确定出进行反馈的反馈信息的目标信道资源，使得不同第一终端设备进行反馈信息的信道资源不同，以此来解决反馈信息的干扰或覆盖问题。
示例性的，与上述图7所示实施例的结构类似，本实施例中以一个第二终端设备与至少两个第一终端设备通过侧行链路进行通信进行说明。其中，至少两个第一终端设备中的每个第一终端设备均可以接收第二终端设备发送的侧行数据信息。同理，本实施例也适用于只有一个第一终端设备的情况。
示例性的，如图10所示，在本实施例中，该信息传输方法可以包括如下步骤：
步骤101：第二终端设备向至少两个第一终端设备发送侧行数据信息。
在本实施例中，在一个通信组中，当第二终端设备需要通过侧行链路与通信内的多个第一终端设备进行通信时，该第二终端设备可以通过组播的方式向通信组内的每个第一终端设备发送侧行数据信息。
在本实施例中，第二终端设备也通过PSCCH向至少两个第一终端设备发送控制信息，通过PSSCH向至少两个第一终端设备发送数据信息。
关于第二终端设备向至少两个第一终端设备发送侧行数据信息的方式与上述图7所示实施例中的类似，区别在于本申请实施例不限定控制信息携带的内容。
步骤102：每个第一终端设备根据接收到的第二终端设备发送的侧行数据信息，确定对该侧行数据信息进行反馈的反馈信息的目标信道资源。
其中，该目标信道资源与其他第一终端设备向第二终端设备发送反馈信息的信道资源不同。
可选的，在本申请的实施例中，每个第一终端设备或网络设备可以将参考信号接收功率划分为多个功率等级，每个功率等级对应一个信道资源集合，也即，利用划分的功率等级对反馈信息的传输资源进行分组，具有不同功率等级的第一终端设备在所属功率等级对应的信道资源集合内发送反馈信息。
示例性的，在本实施例中，侧行链路上的参考信号接收功率SL-RSRP的范围与功率等级的对应关系可以如表1所示，可选的，该功率等级是SL-RSRP等级。表1为SL-RSRP范围与SL-RSRP等级的对应关系。
SL-RSRP等级 SL-RSRP范围
等级0 SL-RSRP<-130dBm
等级1 -130dBm<＝SL-RSRP<-120dBm
等级2 -120dBm<＝SL-RSRP<-110dBm
等级3 -110dBm<＝SL-RSRP<-100dBm
等级4 -100dBm<＝SL-RSRP<-90dBm
等级5 -90dBm<＝SL-RSRP<-80dBm
等级6 -80dBm<＝SL-RSRP<-70dBm
等级7 SL-RSRP>＝-70dBm
值得说明的是，每个功率等级对应的SL-RSRP范围的具体取值可以根据实际情况确定，本实施例并不对其进行限定。
在本实施例中，不同的SL-RSRP等级对应不同的反馈信道传输资源集合，因而，第一终端设备可以根据获取到的侧行数据信息，获取SL-RSRP，进而根据该SL-RSRP所属的功率等级确定出用于承载反馈信息的目标信道资源，该反馈信息是第一终端设备用于反馈该侧行数据信息的是否正确接收的信息。
示例性的，在本实施例中，参照图10所示，在该步骤102之前，该方法还可以包括如下步骤：
步骤102a：每个第一终端设备获取资源映射关系，该资源映射关系用于表征功率等级与信道资源集合的对应关系。
示例性的，该功率等级是SL-RSRP等级。
可选的，在本实施例中，表征功率等级与信道资源集合的对应关系的资源映射关系被配置在每个第一终端设备内，因而，每个第一终端设备在需要发送反馈信息时，可以首先获取该资源映射关系。
可选地，该资源映射关系可以是预配置的、网络配置的或者是终端自主确定的。因而，该步骤至少可以通过如下方式实现：
实现方式1：每个第一终端设备接收网络设备发送的该资源映射关系，该资源映射关系是网络设备配置的。
在本实施例中，网络设备为一个通信组配置资源映射关系，并将配置好的资源映射关系通过网络配置信息发送给通信组内的各个终端设备(包括第一终端设备和第二终端设备)，因而，在本实施例中，每个第一终端设备均可以根据接收到的网络配置信息确定出该资源映射关系。
实现方式2：每个第一终端设备获取预先存储在该第一终端设备中的资源映射关系。
在本实施例中，该资源映射关系预配置在第一终端设备内部，这样每个第一终端设备在需要确定反馈信息的信道资源时，可以根据预配置信息获取预先存储在该第一终端设备中的资源映射关系。
实现方式3，每个第一终端设备根据预先存储的在该第一终端设备中的配置规则，确定资源映射关系；或者，根据从网络设备接收的配置规则，确定该资源映射关系。
在本实施例中，作为一种示例，每个第一终端设备通过与通信组内的其他终端设备进行协商或约定确定出用于表征功率等级与信道资源集合的对应关系的配置规则，并将其存储在第一终端设备中，所以，在本实施例中，当第一终端设备需要获取资源映射关系时，可以直接根据预先存储的该配置规则，确定资源映射关系。
作为一种示例，网络设备可以为一个通信组设定一个资源映射关系的配规则，并将其发送给通信组内的各个终端设备，因而，在本实施例中，每个第一终端设备在需要获取资源映射关系时可以根据从网络设备接收的配置规则确定该资源映射关系。
相应的，该步骤102可以通过如下步骤实现：
步骤102b：每个第一终端设备根据该侧行数据信息和资源映射关系，确定该反馈信息的目标信道资源。
示例性的，在本实施例中，第一终端设备接收到第二终端设备发送的侧行数据信息时，首先获取该侧行数据信息对应的侧行参考信号接收功率，再根据该侧行参考信号接收功率所属的功率等级和资源映射关系，确定该反馈信息的目标信道资源。
具体的，在本实施例中，第一终端设备根据该侧行参考信号接收功率的功率等级和该资源映射关系，确定该侧行信号接收功率所属功率等级对应的信道资源集合，根据该信道资源集合，确定该反馈信息的目标信道资源。
在本实施例中，第一终端设备获取到侧行数据信息时，首先获取该侧行数据信息对应的侧行参考信号接收功率，确定出该侧行参考信号接收功率所属的功率等级，再根据该功率等级和资源映射关系，确定该功率等级对应的信道资源集合，最后基于每个信道资源集合中资源利用信息(例如，空闲资源位置和大小)，确定出该反馈信息的目标信道资源。
示例性的，在本实施例中，不同的功率等级对应的反馈信息的信道资源不同，可以为频域资源不同或者时域资源不同或者码域资源不同，不同的第一终端设备使用具有不同功率等级对应的信道资源，使得同一个通信组内的终端之间的干扰很低。
例如，功率等级0对应的信道资源为子带N，功率等级1对应的信道资源为子带N+1，功率等级2对应的信道资源为子带N+2，以此类推。一个子带包括连续的多个物理资源块(physical resource block，PRB)，因此，具有相同功率等级的终端设备还可以使用该功率等级对应的子带内的不同的PRB，或者使用不同的码域资源，同样可以避免信息覆盖问题。
步骤103：每个第一终端设备根据该目标信道资源向第二终端设备发送反馈信息。
在本申请的实施例中，当第一终端设备确定出用于对该侧行数据信息进行反馈的反馈信息的目标信道资源之后，其可以在该目标信道资源上向第二终端设备发送反馈信息。
值得说明的是，位于同一通信组内的多个第一终端设备在接收到第二终端设备发送的侧行数据信息时，均可以执行上述步骤102和步骤103的方案，从而在避免相关干扰的情况下，实现反馈信息的发送。
相应的，当通信组内的多个第一终端设备在各种的目标信道资源上向第二终端设备发送反馈信息时，第二终端设备可以接收上述至少两个第一终端设备发送的反馈信息，进而可以根据每个第一终端设备发送的反馈信息确定出每个第一终端设备的侧行数据信息的接收情况，进而确定是否需要进行重传。
本申请实施例提供的信息传输方法，第二终端设备向至少两个第一终端设备发送侧行数据信息，每个第一终端设备根据接收到的第二终端设备发送的侧行数据信息，确定对该侧行数据信息进行反馈的反馈信息的目标信道资源，根据该目标信道资源向第二终端设备发送反馈信息。该技术方案，通过确定出每个第一终端设备对该侧行数据信息进行反馈的反馈信息的目标信道资源，由于不同信道资源之间的干扰很低，从而避免了由于距离第二终端设备较远的第一终端设备反馈的反馈信息被检测失败的问题。
图11为本申请实施例提供的信息传输装置实施例一的结构示意图。该装置可以集成在第一终端设备中，也可以为第一终端设备。如图11所示，该装置可以包括：接收模块111、处理模块112和发送模块113。
其中，接收模块111，用于接收第二终端设备发送的侧行数据信息，所述侧行数据信息携带指示信息，所述指示信息用于确定对所述侧行数据信息进行反馈的反馈信息的目标发送功率；
