下面对本公开实施例提供的旁链路信息的传输方法及设备中涉及的一些概念和/或术语做一下解释说明。
旁链路(sidelink)：为UE与UE之间传输(如发送或者接收)信息的链路。UE在旁链路上传输的信息称为旁链路信息。UE在旁链路上与其它UE传输信息的过程称为旁链路通信，旁链路通信可以包括设备到设备(Device-to-Device，D2D)和车到外界(Vehicle-to-Everything，V2X)等通信。其中V2X主要包含了车到车通信(vehicle-to-vehicle，V2V)，车到路通信(vehicle-to-infrastructure，V2I)，车到网络通信(vehicle-to-network，V2N)以及车到人通信(vehicle-to-pedestrian，V2P)。
服务质量(Quality of Service，QoS)：是网络中的一种安全机制，是用来解决网络出现延迟和阻塞等问题的一种技术，可以为网络通信提供更好的服务能力。QoS可以包括传输带宽、传输时延以及丢包率等参数。
本公开实施例提供一种旁链路信息的传输方法及设备，UE可以获取传输 参数，并采用该传输参数，在旁链路上发送或者接收旁链路信息。通过该方案，由于UE可以先获取传输参数，然后再采用该传输参数在旁链路上发送或者接收旁链路信息；因此，当UE处于不同场景(如不同的覆盖范围、频段或移动速度等)时，UE可以获取不同的传输参数，如此在UE采用该传输参数传输旁链路信息时，能够动态适应不同场景下传输旁链路信息的需求。
本公开实施例中的传输参数可以包括参数名称和参数值。其中，该参数值可以为一个具体的数值或者为一个取值范围。具体可以根据实际使用需求确定，本公开实施例不作限定。
本公开实施例提供的旁链路信息的传输方法及设备，可以应用于通信系统中。具体可以应用于在该通信系统处于不同场景下，UE采用传输参数传输旁链路信息的过程中。
需要说明的是，本公开实施例中，上述通信系统可以包括长期演进(Long Term Evolution，LTE)通信系统、NR通信系统以及后续通信系统等。
示例性的，LTE通信系统可以为LTE中的旁链路通信系统，NR通信系统可以为NR中的旁链路通信系统，后续通信系统可以为后续的旁链路通信系统。
示例性的，图1示出了本公开实施例提供的一种通信系统的架构示意图。如图1所示，该通信系统可以包括第一UE 01、接入网设备02和第二UE 03。其中，第一UE 01与接入网设备02之间可以建立连接，接入网设备02与第二UE 03之间可以建立连接。并且第一UE 01和第二UE 03之间也可以建立连接。可以理解，第一UE 01和第二UE 03之间的通信即为旁链路通信。
需要说明的是，本公开实施例中，上述如图1所示的第一UE 01和接入网设备02之间可以是无线连接；接入网设备02与第二UE 03之间也可以是无线连接，第一UE 01和第二UE 03之间也可以是无线连接。为了更加清楚的示意第一UE 01和接入网设备02之间，接入网设备02与第二UE 03之间，以及第一UE 01和第二UE 03之间的连接关系，图1是以实线示意第一UE 01和接入网设备02之间，接入网设备02与第二UE 03之间，以及第一UE 01和第二UE 03之间的连接关系的。
UE(如图1所示的第一UE 01或者第二UE 03)是一种向用户提供语音和/或数据连通性的设备，具有有线/无线连接功能的手持式设备，或连接到 无线调制解调器的其他处理设备。UE可以经过无线接入网(Radio Access Network，RAN)与一个或多个核心网设备进行通信。UE可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，也可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与RAN交换语言和/或数据，例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)等设备。UE也可以称为用户代理(User Agent)或者终端设备等。
接入网设备02可以为基站。基站是一种部署在RAN中用于为UE提供无线通信功能的装置。基站可以包括各种形式的宏基站、微基站、中继站、接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如，在第三代移动通信(3G)网络中，称为基站(Node B)，在LTE系统中，称为演进型基站(evolved NodeB，eNB或eNodeB)等等。随着通信技术的演进，“基站”这一名称可能会发生变化。
下面结合附图，通过具体的实施例及其应用场景对本公开实施例提供的一种旁链路信息的传输方法及设备进行详细地说明。
目前，相关技术中，UE采用固定的传输参数在旁链路上传输旁链路信息，而随着5G技术的发展，NR要求NR系统支持大覆盖、高频段和高移动速度。如果UE在NR系统中大覆盖、高频段、高移动速度等场景下继续采用固定的传输参数传输旁链路信息，那么可能会导致信道时间选择性衰变、毫米波传输距离短等问题，因此上述采用固定的传输参数传输旁链路信息的方式已经无法满足NR系统中大覆盖、高频段、高移动速度等场景下传输旁链路信息的需求。
为了解决上述技术问题，本公开实施例提供一种旁链路信息的传输方法，下面以第一UE与第二UE之间的交互为例，并且假设第一UE为发送端UE，第二UE为接收端UE，对本公开实施例提供的旁链路信息的传输方法进行示例性的描述。
本公开的各个方法实施例中，为了区分第一UE获取的传输参数和第二UE获取的传输参数，可以将第一UE获取的传输参数称为第一传输参数，将 第二UE获取的传输参数称为第二传输参数。并且，为了区分第一UE获取传输参数时采用的映射关系和第二UE获取传输参数时采用的映射关系，可以将第一UE获取传输参数时采用的映射关系称为第一映射关系，将第二UE获取传输参数时采用的映射关系称为第二映射关系。以及，为了区分第一UE接收的高层发送的指示信息和第二UE接收的高层发送的指示信息，可以将第一UE接收的高层发送的指示信息称为第一指示信息，将第二UE接收的高层发送的指示信息称为第二指示信息。
基于如图1所示的通信系统，本公开实施例提供一种旁链路信息的传输方法，如图2所示，该旁链路信息的传输方法可以包括下述的步骤101-步骤104。
步骤101、第一UE获取第一传输参数。
其中，上述第一传输参数可以用于第一UE在旁链路上发送旁链路信息。
可选的，本公开实施例中，上述第一传输参数可以包括下述的至少一项：传输波形、数值配置信息、调制与编码策略(Modulation and Coding Scheme，MCS)、传输带宽、传输资源、载波聚合模式、传输周期、重传复用方式、重传次数、重传一次所需的时域时长、完成所有重传所需的时域时长、重传的时域间隔、重传一次所需的带宽、完成所有重传所需的总带宽、重传的频域间隔、重传周期、传输功率、功控目标、最大传输功率、功率调整因子、传输功率控制(Transmitted Power Control，TPC)命令、信道之间的功率谱密度差、发送分集方式、预编码方式、传输序列、传输格式、信道复用形式、资源池复用形式、拥塞控制策略、合并方式、通信距离需求、传输时延需求、信号与干扰加噪声比需求、信噪比需求、传输速率需求、块差错率需求、误码率需求、误差向量幅度需求、移动速度需求、信道忙碌率(Channel Busy Ratio，CBR)需求、信道占用率(Channel Occupancy Ratio)需求，以及可靠度需求等。

可选的，本公开实施例中，上述数值配置信息(numerology)可以包括CP和子载波间隔(Subcarrier Spacing，SCS)中的至少一项。在NR系统中，可以支持多种数值配置信息，例如子载波间隔可以包括15kHz、30kHz、60kHz、120kHz，以及240kHz等。其中，SCS增大，CP随之减小。在SCS较小，且CP较长的情况下，由于能够通过较长的CP避免符号间干扰，因此这种情况可以适用于传输时延较大和/或同步定时不理想的场景。一定SCS范围内，较大的SCS在大多普勒效应下性能比于较小的SCS在大多普勒效应下性能稳定，因此较大的SCS可以适用于UE高移动速度的场景。另外，由于SCS较大时，一个OFDM符号的时长较短，从而能够降低波束扫描需要的总时长，因此较大的SCS可以适用于大基数的波束扫描的场景。
可选的，本公开实施例中，上述载波聚合模式可以用于指示是否进行载波聚合，以及使用当前聚合载波中所有载波单元(Component Carrier，CC)中的几个CC传输数据。

可以理解，上述PSSCH可以用于传输数据信号；上述PSCCH可以用于传输控制信号；上述PSBCH可以用于传输广播信号；上述PSDCH可以用于传输发现信号。
可选的，本公开实施例中，上述发送分集方式可以包括是否发送分集以及分集的流数。其中，是否发送分集表示发送数据时是否采用分集的方式发送；分集的流数表示采用分集的方式发送数据时数据流的个数。
可选的，本公开实施例中，上述传输序列可以包括序列映射方法、序列类型、序列扰码，以及序列的循环移位(Cycle Shift)等中的至少一项。该序列映射方法可以包含：先映射频域后映射时域；或者，先映射时域后映射频域；或者频域上按照频域编号从大到小的顺序映射；或者频域上按照频域编号从小到大的顺序映射。
可选的，本公开实施例中，上述传输格式可以包括参考信号(Reference Signal，RS)占据符号数、RS占据时域位置、RS密度以及参考信号是否为梳状(comb)，以及参考信号使用的梳状数目等中的至少一项。
可选的，本公开实施例中，上述信号复用形式可以为控制信号和数据信号进行FDM或者TDM。其中，控制信号和数据信号的时域和/或频域可以相邻或者不相邻。
可选的，本公开实施例中，上述资源池复用形式可以为至少两个资源池为FDM、TDM或者重叠等。
可选的，本公开实施例中，上述拥塞控制策略可以包括基站集中控制和用户自行调整。
可选的，本公开实施例中，上述合并方式可以包括分集接收方式。其中，分集接收表示接收数据时采用分集的方式接收。
可选的，本公开实施例中，上述移动速度需求可以为绝对速度需求或者相对速度需求。
步骤102、第一UE采用第一传输参数，在旁链路上向第二UE发送旁链路信息。
本公开实施例中，第一UE可以采用第一传输参数，在旁链路上向第二UE发送物理层信号，该物理层信号中携带有旁链路信息。
可选的，本公开实施例中，上述物理层信号可以为在旁链路上传输的广播信号、控制信号、数据信号、同步信号、发现信号或者参考信号等。
步骤103、第二UE获取第二传输参数。
可选的，本公开实施例中，第二UE获取的第二传输参数可以是预配置或者预定义的；或者，也可以是第二UE根据映射关系(即第二映射关系)获取的；或者，也可以是第二UE根据高层发送的指示信息(即第二指示信息)获取的；或者，还可以是接收第一UE发送的。
本公开实施例中，上述步骤101中第一UE获取的第一传输参数和步骤103中第二UE获取的第二传输参数可以相同，也可以不同，还可以部分相同。具体的可以根据实际使用需求确定，本公开实施例不作限定。
步骤104、第二UE采用第二传输参数，在旁链路上接收第一UE发送的旁链路信息。
需要说明的是，本公开实施例中，第二UE的数量可以为一个或者多个，本公开实施例为了便于更好地描述第一UE与第二UE之间的交互，是以第二UE的数量为一个为例进行说明的。当第二UE的数量有多个时，第一UE与多个第二UE中的每个第二UE之间的交互，均与上述实施例中描述的第一UE与第二UE之间的交互类似，此处不再赘述。
本公开实施例中，由于第一UE采用的第一传输参数为在第一UE当前所处的场景下，根据第一UE当前的实际需求获取的，因此第一UE在采用该第一传输参数向第二UE发送旁链路信息时，能够适应当前场景下第一UE向第二UE发送旁链路信息的需求。
本公开实施例提供一种旁链路信息的传输方法，第一UE可以获取第一传输参数，并采用该第一传输参数，在旁链路上发送或者接收旁链路信息。通过该方案，由于第一UE可以先获取第一传输参数，然后再采用该第一传输参数在旁链路上发送或者接收旁链路信息；因此，当第一UE处于不同场景(如 不同的覆盖范围、频段或移动速度等)时，第一UE可以获取不同的第一传输参数，如此在第一UE采用该第一传输参数传输旁链路信息时，能够动态适应不同场景下传输旁链路信息的需求。
下面结合附图，通过具体的实施例及其应用场景对本公开实施例中第一UE获取第一传输参数的具体方法进行详细地说明。
可选的，在本公开实施例的第一种可能的实现方式中，结合图2，如图3所示，上述步骤101具体可以通过下述的步骤101a实现。
步骤101a、第一UE获取预配置或者预定义的第一传输参数。
可选的，本公开实施例中，第一UE可以获取第一UE的厂商预配置、协议预定义或者用户预定义的第一传输参数。
需要说明的是，本公开实施例中，预配置可以理解为第一UE的厂商预配置，预定义可以理解为协议预定义或者用户预定义。
本公开实施例中，由于第一UE在不同场景下获取的预配置或者预定义的第一传输参数可能不同，因此第一UE在采用预配置或者预定义的第一传输参数传输旁链路信息时，能够适应不同场景下传输旁链路信息的需求。
可选的，本公开实施例中，在本公开实施例的第二种可能的实现方式中，结合图2，如图4所示，在上述步骤101之前，本公开实施例提供的旁链路信息的传输方法还可以包括下述的步骤201，并且上述步骤101具体可以通过下述的步骤101b实现。
步骤201、第一UE获取第一映射关系。
其中，上述第一映射关系为QoS需求与第一传输参数之间的映射关系。
可选的，本公开实施例中，上述第一映射关系可以是预配置的；或者，上述第一映射关系可以是预定义的；或者，上述第一映射关系可以是其它UE为第一UE配置的；或者，上述第一映射关系可以是基站为第一UE配置的，该基站为第一UE提供服务。
需要说明的是，本公开实施例中，上述其它UE可以是具有高优先级的UE。具有高优先级的UE可以是具备高旁链路通信能力的UE。其中，UE具备高旁链路通信能力是指UE具有控制、调度、管理、分配、协作，以及处理等能力中的至少一项能力。另外，上述其它UE可以通过广播(例如可以是周期 性广播或者非周期性广播)的形式为第一UE配置第一映射关系。
可选的，本公开实施例中，可以预配置、预定义、由其它UE为第一UE配置或者由基站为第一UE配置多个第一映射关系。这样，第一UE可以根据接收到的QoS需求(具体可以是高层发送给第一UE的)，从该多个第一映射关系中获取与该QoS需求对应的第一映射关系。
示例性的，以多个第一映射关系是预配置的为例，假设预配置的第一映射关系有3个。如表1所示，示出了本公开实施例提供的一种QoS需求多个第一映射关系的实例。

Figure PCTCN2019081893-appb-000001
如表1所示，QoS需求1对应的第一映射关系为映射关系1；QoS需求2对应的第一映射关系为映射关系2；QoS需求3对应的第一映射关系为映射关系3。第一UE可以根据接收到的QoS需求，从映射关系1、映射关系2和映射关系3中获取与该QoS需求对应的第一映射关系。示例性的，假设第一UE接收到的QoS需求为QoS需求1，那么第一UE可以根据该QoS需求1，从映射关系1、映射关系2和映射关系3中获取与该QoS需求1对应的第一映射关系为映射关系1。
可选的，本公开实施例中，上述步骤201具体可以通过下述的步骤201a和步骤201b实现。
步骤201a、第一UE接收高层发送的QoS需求。
本公开实施例中，在网络体系中，高层可以为接入层(Access Stratum，AS)以上的层。
本公开实施例中，第一UE可以在AS传输旁链路信息。
可选的，本公开实施例中，QoS需求可以指QoS的取值或者QoS的取值范围。
步骤201b、第一UE根据QoS需求，获取与所述QoS需求对应的第一映射关系。
可选的，本公开实施例中，第一UE可以根据高层发送的QoS需求，从多个第一映射关系中获取与该QoS需求对应的第一映射关系。
示例性的，参考表1，假设第一UE接收到的QoS需求为QoS需求2，则第一UE可以根据QoS需求2从多个第一映射关系(如表1所示的映射关系1、映射关系2和映射关系3)中获取与QoS需求2对应的第一映射关系，即如表1所示的映射关系2。
可选的，本公开实施例中，以上述多个第一映射关系中的一个第一映射关系为例，该第一映射关系可以包括至少两个子映射关系。假设至少两个子映射关系具体包括n个子映射关系，那么该n个子映射关系分别可以为子映射关系1、子映射关系2、……、子映射关系n。并且，子映射关系1可以记为QoS需求→中间参数1，子映射关系2可以记为中间参数1→中间参数2，……，子映射关系n可以记为中间参数n-1→第一传输参数。
可选的，本公开实施例中，上述各个子映射关系中的中间参数(例如上述中间参数1、中间参数2、……、中间参数n-1)可以为传输参数，也可以为非传输参数，具体可以根据实际使用需求设置，本公开实施例不作限定。
下面以上述各个子映射关系中的中间参数为传输参数为例，对本公开实施例中的至少两个子映射关系进行示例性的说明。
示例性的，结合表1，假设映射关系1包括三个子映射关系(即上述n＝3)，分别记为QoS需求1→传输参数a1、传输参数a1→传输参数a2和传输参数a2→传输参数a，那么映射关系1可以记为QoS需求1→传输参数a1→传输参数a2→传输参数a；假设映射关系2包括两个子映射关系，分别记为QoS需求2→传输参数b1和传输参数b1→传输参数b，那么映射关系2可以记为QoS需求2→传输参数b1→传输参数b；假设映射关系3包括三个子映射关系，分别记为QoS需求3→传输参数c1、传输参数c1→传输参数c2和传输参数c2→传输参数c，那么映射关系3可以记为QoS需求3→传输参数c1→传输参数c2→传输参数c。
步骤101b、第一UE根据第一映射关系，获取第一传输参数。
示例性的，结合表1，如表2所示，示出了本公开实施例提供的第一映射关系(表示QoS需求与第一传输参数之间的映射关系)的实例。
表2
第一映射关系 QoS需求 第一传输参数
映射关系1 QoS需求1 传输参数a
映射关系2 QoS需求2 传输参数b
映射关系3 QoS需求3 传输参数c
如表2所示，映射关系1为QoS需求1与传输参数a之间的映射关系，可以记为QoS需求1→传输参数a；映射关系2为QoS需求2与传输参数b之间的映射关系，可以记为QoS需求2→传输参数b；映射关系3为QoS需求3与传输参数c之间的映射关系，可以记为QoS需求3→传输参数c。若第一UE接收到的QoS需求为QoS需求1，则第一UE可以从映射关系1、映射关系2和映射关系3中获取的与该QoS需求1对应的映射关系1，然后第一UE再根据该映射关系1获取传输参数a。如此，第一UE可以根据接收到的QoS需求1，获取传输参数a。
示例性的，假设QoS需求的取值范围为A1时，A1对应的第一传输参数为传输波形DFT-S-OFDM；QoS需求的取值范围为A2时，A2对应的第一传输参数为传输波形CP-OFDM。若第一UE接收的QoS需求为QoS需求1，且该QoS需求1的取值位于A1内，那么第一UE可以根据该QoS需求1获取映射关系1(即QoS需求1→传输参数a)，并且根据映射关系1获取传输参数a为传输波形DFT-S-OFDM。若第一UE接收的QoS需求为QoS需求2，且该QoS需求2的取值位于A2内，那么第一UE可以根据该QoS需求2获取映射关系2(即QoS需求2→传输参数b)，并且根据映射关系2获取传输参数b为传输波形CP-OFDM。
又示例性的，假设QoS需求的取值范围为A3，A3对应的第一传输参数为传输波形CP-OFDM；QoS需求的取值范围为A4，A4对应的第一传输参数为传输波形DFT-S-OFDM；QoS需求的取值范围为A5，A5对应的第一传输参数为传输波形CP-OFDM和DFT-S-OFDM。若第一UE接收的QoS需求为QoS需求1，且该QoS需求1的取值位于A3内，那么第一UE可以根据该QoS需求1获取映 射关系1(即QoS需求1→传输参数a)，并且根据映射关系1获取传输参数a为传输波形CP-OFDM。若第一UE接收的QoS需求为QoS需求2，且该QoS需求2的取值位于A4内，那么第一UE可以根据该QoS需求2获取映射关系2(即QoS需求2→传输参数b)，并且根据映射关系2获取传输参数b为传输波形DFT-S-OFDM。若第一UE接收的QoS需求为QoS需求3，且该QoS需求3的取值位于A5内，那么第一UE可以根据该QoS需求3获取映射关系3(即QoS需求3→传输参数c)，并且根据映射关系3获取传输参数c为传输波形CP-OFDM和DFT-S-OFDM中的任一种。
可以理解，上述A5可以为A3和A4的重叠部分。即当第一UE接收的QoS需求的取值位于该重叠部分时，第一UE获取的第一传输参数可以为与A3对应的第一传输参数和与A4对应的第一传输参数中的任一种。
又示例性的，假设QoS需求的取值范围为B1时，B1对应的第一传输参数为取值范围为P1的传输功率1；QoS需求的取值范围为B2时，B2对应的第一传输参数为取值范围为P2的传输功率2。若第一UE接收的QoS需求为QoS需求1，且该QoS需求1的取值位于B1内，那么第一UE可以根据该QoS需求1获取映射关系1(即QoS需求1→传输参数a)，并且根据映射关系1获取传输参数a为取值范围为P1的传输功率1。若第一UE接收的QoS需求为QoS需求2，且该QoS需求2的取值位于B2内，那么第一UE可以根据该QoS需求2获取映射关系2(即QoS需求2→传输参数b)，并且根据映射关系2获取传输参数b为取值范围为P2的传输功率2。
可以理解，本公开实施例中，第一UE获取的传输波形为第一UE发送携带旁链路信息的物理层信号的波形。
需要说明的是，本公开实施例中，由于QoS需求的取值范围可能会有重叠(如上述A1和A2可能会有重叠)，因此，当QoS需求的取值范围重叠时，第一UE可以获取A1对应的第一传输参数和A2对应的第一传输参数中的任意一个第一传输参数；或者，第一UE还可以采用其他方式获取A1对应的第一传输参数和A2对应的第一传输参数中的一个第一传输参数。具体可以根据实际使用需求设置，本公开实施例不作限定。
本公开实施例中，由于在不同场景下，第一UE获取的第一映射关系不同， 那么第一UE根据第一映射关系获取的第一传输参数则不同，因此第一UE在采用获取的第一传输参数传输旁链路信息时，能够适应不同场景下传输旁链路信息的需求。
可选的，本公开实施例中，上述第一UE根据高层发送的QoS需求获取的第一映射关系可以包括至少两个子映射关系。上述步骤101b具体可以通过下述的步骤101b′实现。
步骤101b′、第一UE根据至少两个子映射关系，获取第一传输参数。
需要说明的是，本公开实施例中，对于至少两个子映射关系的描述，具体可以参见上述步骤201b中对至少两个子映射关系的相关描述，此处不再赘述。
示例性的，结合表1，假设映射关系2可以包括两个子映射关系，该两个子映射关系分别为子映射关系1和子映射关系2，且子映射关系1记为QoS需求2→传输参数b1，子映射关系2记为传输参数b1→传输参数b。第一UE可以根据子映射关系1(即QoS需求2→传输参数b1)获取到传输参数b1，然后再根据子映射关系2(即传输参数b1→传输参数b)获取到传输参数b。
例如，假设QoS需求的取值对应通信距离需求(具体可以为旁链路通信距离需求)，当通信距离需求的取值范围为X1时，X1对应的第一传输参数为传输波形DFT-S-OFDM；当通信距离需求的取值范围为X2时，X2对应的第一传输参数为传输波形CP-OFDM。若第一UE接收的QoS需求为QoS需求2，那么第一UE可以根据该QoS需求2获取映射关系2(即QoS需求2→传输参数b1和传输参数b1→传输参数b)，并且根据映射关系2中的子映射关系1(即QoS需求2→传输参数b1)获取传输参数b1为通信距离需求。当该通信距离需求的取值位于X1内时，第一UE可以再根据映射关系2中的子映射关系2(即传输参数b1→传输参数b)获取传输参数b为传输波形DFT-S-OFDM；当该通信距离需求的取值位于X2内时，第一UE可以再根据映射关系2中的子映射关系2(即传输参数b1→传输参数b)获取传输参数b为传输波形CP-OFDM。
又例如，假设QoS需求的取值对应通信距离需求(具体可以为旁链路通信距离需求)，当通信距离需求的取值范围为X3时，X3对应的第一传输参数为取值范围为P3的传输功率3；当通信距离需求的取值范围为X4时，X4对 应的第一传输参数为取值范围为P4的传输功率4。若第一UE接收的QoS需求为QoS需求2，那么第一UE可以根据该QoS需求2获取映射关系2(即QoS需求2→传输参数b1和传输参数b1→传输参数b)，并且根据映射关系2中的子映射关系1(即QoS需求2→传输参数b1)获取传输参数b1为通信距离需求。当该通信距离需求的取值位于X3内时，第一UE可以再根据映射关系2中的子映射关系2(即传输参数b1→传输参数b)获取传输参数b为取值范围为P3的传输功率3；当该通信距离需求的取值位于X4内时，第一UE可以再根据映射关系2中的子映射关系2(即传输参数b1→传输参数b)获取传输参数b为取值范围为P4的传输功率4。
又例如，假设QoS需求的取值对应功率调整因子(例如传输功率调整因子)，当功率调整因子的取值范围为Y1时，Y1对应的第一传输参数为根据该功率调整因子调整后的功率(例如该调整后的功率可以为取值范围为P5的传输功率5)；当功率调整因子的取值范围为Y2时，Y2对应的第一传输参数为根据该功率调整因子调整后的功率(例如该调整后的功率可以为取值范围为P6的传输功率6)。若第一UE接收的QoS需求为QoS需求2，那么第一UE可以根据该QoS需求2获取映射关系2(即QoS需求2→传输参数b1和传输参数b1→传输参数b)，并且根据映射关系2中的子映射关系1(即QoS需求2→传输参数b1)获取传输参数b1为功率调整因子。当该功率调整因子的取值位于Y1内时，第一UE可以再根据映射关系2中的子映射关系2(即传输参数b1→传输参数b)获取传输参数b为根据该功率调整因子调整后的功率，即取值范围为P5的传输功率5；当该功率调整因子的取值位于Y2内时，第一UE可以再根据映射关系2中的子映射关系2(即传输参数b1→传输参数b)获取传输参数b为根据该功率调整因子调整后的功率，即取值范围为P6的传输功率6。
又例如，假设QoS需求的取值对应可靠度需求(具体可以为旁链路信息传输的可靠度需求)，当可靠度需求的取值范围为Z1时，Z1对应的第一传输参数为重传次数N1；当可靠度需求的取值范围为Z2时，Z2对应的第一传输参数为重传次数N2。若第一UE接收的QoS需求为QoS需求2，那么第一UE可以根据该QoS需求2获取映射关系2(即QoS需求2→传输参数b1和传输 参数b1→传输参数b)，并且根据映射关系2中的子映射关系1(即QoS需求2→传输参数b1)获取传输参数b1为可靠度需求。当该可靠度需求的取值位于Z1内时，第一UE可以再根据映射关系2中的子映射关系2(即传输参数b1→传输参数b)获取传输参数b为重传次数N1；当该通信距离需求的取值位于Z2内时，第一UE可以再根据映射关系2中的子映射关系2(即传输参数b1→传输参数b)获取传输参数b为重传次数N2。
本公开实施例中，由于在不同场景下，第一UE获取的至少两个子映射关系不同，那么第一UE根据至少两个子映射关系获取的第一传输参数则不同，因此第一UE在采用获取的第一传输参数传输旁链路信息时，能够适应不同场景下传输旁链路信息的需求。
可选的，本公开实施例中，在本公开实施例的第三种可能的实现方式中，结合图2，如图5所示，在上述步骤101之前，本公开实施例提供的旁链路信息的传输方法还可以包括下述的步骤301，并且上述步骤101具体可以通过下述的步骤101c实现。
步骤301、第一UE接收高层发送的第一指示信息。
其中，第一指示信息可以用于指示第一UE获取预配置或者预定义的第一传输参数。
步骤101c、第一UE根据第一指示信息，获取预配置或者预定义的第一传输参数。
需要说明的是，本公开实施例中，第一UE在接收到高层发送的第一指示信息的情况下，也可能接收到高层发送的QoS需求，此时第一UE仍然根据高层发送的第一指示信息的指示，获取预配置或者预定义的第一传输参数。
本公开实施例中，由于在不同场景下，高层发送的第一指示信息可能不同，那么第一UE接收的第一指示信息则不同，并且第一UE根据第一指示信息获取的预配置或者预定义的第一传输参数也不同，因此第一UE在采用这些第一传输参数传输旁链路信息时，能够适应不同场景下传输旁链路信息的需求。
可选的，本公开实施例中，在本公开实施例的第四种可能的实现方式中，结合图2，如图6所示，上述步骤101具体可以通过下述的步骤101d实现。
步骤101d、第一UE在旁链路上接收其它UE发送的第一传输参数。
可选的，本公开实施例中，其他UE可以包括第二UE。
本公开实施例中，由于第一UE在不同场景下接收到其它UE发送的第一传输参数可能不同，因此第一UE在采用接收的第一传输参数传输旁链路信息时，能够适应不同场景下传输旁链路信息的需求。
需要说明的是，本公开实施例中，第二UE获取第二传输参数的具体方法与第一UE获取第一传输参数的具体方法类似，具体可以参见本公开实施例中上述四种可能的实现方式(即第一种可能的实现方式至第四种可能的实现方式)中对第一UE获取第一传输参数的具体方法的相关描述，此处不再赘述。
可选的，本公开实施例中，在上述步骤101之后，结合图2，如图7所示，本公开实施例提供的旁链路信息的传输方法还可以包括下述的步骤401。
步骤401、第一UE在旁链路上向第二UE发送第一传输参数。
本公开实施例中，第一UE可以在旁链路上向第二UE发送物理层信号，该物理层信号中携带有第一传输参数。
可以理解，如图7所示的实施例中，上述第二UE获取的第二传输参数可以包括该第一传输参数。
需要说明的是，本公开实施例中，一种可能的实现方式中，第一UE可以先执行步骤401，再执行步骤102；即第一UE可以先向第二UE发送第一传输参数，再向第二UE发送旁链路信息。另一种可能的实现方式中，第一UE可以同时执行步骤102和步骤401；即第一UE可以同时向第二UE发送第一传输参数和旁链路信息。
可选的，本公开实施例中，上述一种可能的实现方式中，第一UE可以通过两个不同的物理层信号向第二UE发送第一传输参数和旁链路信息。上述另一种可能的实现方式中，第一UE可以通过一个物理层信号向第二UE发送第一传输参数和旁链路信息。
本公开实施例中，由于第一UE向第二UE发送的第一传输参数为第一UE向第二UE发送旁链路信息时采用的传输参数，因此在第一UE向第二UE发送该第一传输参数之后，可以使得第二UE能够准确地获取该第一传输参数，从而第二UE可以根据该第一传输参数准确地接收第一UE在旁链路上发送的旁 链路信息。如此，可以提高第二UE接收数据的准确性。
本公开实施例中，若第一UE获取的第一传输参数为其它UE(例如第二UE)发送的，那么第一UE获取的第一传输参数(即第二UE发送给第一UE的传输参数，这种场景下，第一UE获取的第一传输参数可以包括第二UE获取的第二传输参数)可以用于指示第二UE接收旁链路信息的接收行为(例如接收方式)，如此第一UE接收到该第一传输参数之后，第一UE可以根据该第一传输参数确定第一UE向第二UE发送旁链路信息的发送行为(例如发送方式)，然后第一UE可以按照该发送行为向第二UE发送旁链路信息。
例如，假设第一UE获取的第一传输参数(即第二UE发送给第一UE的传输参数)可以用于指示第二UE接收旁链路信息的接收方式为分集接收方式，那么第一UE接收到该第一传输参数之后，第一UE可以根据该第一传输参数确定第一UE向第二UE发送旁链路信息的发送方式为发送分集方式，然后第一UE可以按照该发送分集方式向第二UE发送旁链路信息。
当然，实际实现中，第一UE接收到第二UE发送的传输参数(用于指示第二UE接收旁链路信息的接收方式)之后，第一UE也可以忽略该传输参数，并按照通常情况下的方式(例如采用相关技术的固定参数的方式)向第二UE发送旁链路信息。
需要说明的是，上述实施例是以第一UE作为发送端UE，第二UE作为接收端UE为例，对本公开实施例提供的旁链路信息的传输方法进行示例性的描述的。实际执行中，第一UE也可以作为接收端UE，第二UE也可以作为发送端UE。当第二UE作为发送端UE时，第二UE获取的第二传输参数可以用于第二UE向第一UE发送旁链路信息；并且，当第二UE作为发送端UE时，第二UE可以将第二UE获取的第二传输参数发送给第一UE，用于第一UE接收第二UE发送的旁链路信息。当第一UE作为接收端UE时，第一UE获取的第一传输参数可以用于接收第二UE发送的旁链路信息；并且，当第一UE作为接收端UE时，第一UE也可以将第一UE获取的第一传输参数发送给第二UE，用于第二UE向第一UE发送旁链路信息。具体的，第一UE作为接收端UE，第二UE作为发送端UE时，第一UE与第二UE之间的交互过程与上述实施例中第一UE作为发送端UE，第二UE作为接收端UE时描述的第一UE与第二UE 之间的交互过程类似，具体可以参见上述实施例中的相关描述，此处不再赘述。
