一种通信方法及装置
相关申请的交叉引用
本申请要求在2021年10月14日提交中国专利局、申请号为202111196242.9、申请名称为“一种通信方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
随着移动通信的高速发展，新业务类型，如视频聊天、虚拟现实(virtual reality，VR)/增强现实(augmented reality，AR)等数据业务的普遍使用提高了用户对带宽的需求。设备到设备(device-to-device，D2D)通信允许终端设备之间直接进行通信，可以在小区网络的控制下与小区用户共享频谱资源，有效的提高频谱资源的利用率。D2D通信包括一对多通信(one to many communication)以及一对一通信(one to one communication)。一对多通信对应于组播和广播通信，一对一通信对应于单播通信。在一对一通信中，若两个终端设备之间的距离小于预设距离，则二者可在相互发现之后建立邻近业务通信5(prose communication 5，PC5)连接，并通过PC5接口进行直接通信。
两个终端设备可分别为业务数据的发送端和接收端，发送端和接收端可通过授权频谱方式相互传输业务数据，具体地，授权频谱方式对应于授权频谱，发送端可从授权频谱中确定出授权频谱资源，然后在该确定出的授权频谱资源上向接收端发送业务数据。由于授权频谱受限，目前引入发送端和接收端通过非授权频谱方式相互传输业务数据的实现方式。
如此，发送端和接收端之间传输业务数据的频谱方式可以是授权频谱方式或非授权频谱方式，如何合理地确定出该频谱方式成为亟待解决的技术问题。

为方便对本申请实施例的理解，首先介绍一下本申请实施例涉及到的概念和基础知识。
1、5G QoS管理
在5G系统中，为了保证业务端到端的服务质量，提出了基于QoS flow的5G QoS模型，可参见图2所示。该5G QoS模型支持保证比特速率(guaranteed bit rate，GRB)的QoS flow(GBR QoS flow)和不保证比特速率的QoS flow(Non-GBR QoS flow)，使用同一个QoS flow控制的数据包接收相同的传输处理(如调度、准入门限等)。
对于一个终端设备，其可以与5G网络建立一个或者多个PDU会话；每个PDU会话中可以建立一个或者多个QoS flow。每个QoS flow由一个QoS flow标识(QoS flow identifier，QFI)识别，QoS flow标识在PDU会话中唯一标识一个QoS flow。一个QoS flow为GBR QoS flow还是Non-GBR QoS flow，由对应的QoS配置文件(QoS profile)确定。
对于GBR QoS flow，GBR QoS flow对应的QoS配置文件中必须包含以下QoS参数：5G QoS指示符(5G QoS identifier，5QI)、分配保持优先级(allocation and retention priority，ARP)、保证流比特速率(guaranteed flow bit rate，GFBR)和最大流比特速率(maximum flow bit rate，MFBR)。可选的，GBR QoS flow对应的QoS配置文件还可包含QoS通知控制(QoS  notification control，QNC)。根据QoS配置文件是否包含QNC将GBR QoS flow分为需要QNC的GRB QoS flow和不需要QNC的GBR QoS flow。对于需要QNC的GBR QoS flow，当RAN检测到对应的QoS flow资源不能被满足时，RAN通知SMF该事件，再通知PCF。进一步的，SMF可以发起QoS flow删除或者修改流程。
对于Non-GBR QoS flow，Non-GBR QoS flow对应的QoS配置文件中必须包含以下QoS参数：5QI、ARP；可选的，Non-GBR QoS flow对应的QoS配置文件中还可包含反转QoS属性(Reflective QoS Attribute，RQA)。
具体地QoS参数定义如下：
5QI：是一个标量，用于索引到对应的5G QoS特征；5QI分为标准化的5QI、预配置的5QI和动态分配的5QI。对于标准化的5QI，与一组标准化的5G QoS特征值一一对应；对于预配置的5QI，对应的5G QoS特征值预配置在接入网络节点(AN)；对于动态分配的5QI，对应的5G QoS特征包含在QoS配置文件中发送给AN。QoS特征值包括资源类型(resource type，资源类型分为GBR和Non-GBR)，优先级级别(priority level)，数据包时延预算(packet delay budget，可理解为数据包从终端设备到UPF的时延)，数据包错误概率(packet error rate)，最大数据突发量(maximum data burst volume)，平均窗口(averaging window，可用于计算GBR对应的速率)。
ARP：包含优先等级、抢占能力和被抢占能力；
RQA：用于指示使用对应QoS flow传输的业务使用反转QoS；
QNC：用于指示RAN在QoS flow的使用期当GFBR不能满足时是否通知网络；
GFBR：代表期望提供给GBR QoS flow的比特速率；
MFBR：限制提供给GBR QoS flow的比特速率，即提供给GBR QoS flow的最大比特速率。如超过该比特速率时，数据包可以被丢弃。
5G网络可以通过信令面执行QoS控制的管理流程，SMF基于QoS和业务需求进行业务数据流(service data flow，SDF)到QoS flow的绑定。SMF根据本地策略或者PCF发送的策略与计费控制(policy and charging control，PCC)规则，为SDF分配新QoS flow的QoS flow标识，推算出QoS配置文件和相应的数据包检测规则(packet detection rule，PDR)信息。其中，PCC规则包括两种类型：动态PCC规则和预定义的PCC规则。动态PCC规则由PCF提供给SMF，预定义的PCC规则配置在SMF上。PCC规则中包括业务数据流检测相关、计费相关和策略控制(policy control)相关等。业务数据流检测相关包括业务数据流模板(SDF template，一个PCC规则中的业务数据流模板检测出的数据包形成一个SDF)及模板优先级。策略控制相关包括Gate status(业务数据流可通过或丢弃)、被授权的QoS参数(5QI、ARP、maximum bitrate，guaranteed bitrate等)、QNC、Reflective QoS Control。其中，maximum bitrate为该业务数据流最大的比特速率，guaranteed bitrate为该业务数据流保证的比特速率。
2、D2D QoS管理
在5G的D2D通信中，两个终端设备(可分别表示为UE1和UE2)之间可建立一个或者多个PC5链路，该PC5链路可以是PC5单播链路(unicast link)。进一步的，每个PC5链路与一对应用层标识(APP Layer ID)对应。如图3为本申请示例性提供的一种D2D通信中基于QoS flow的QoS模型，其中PC5链路1与应用层标识1、应用层标识2相对应， 其中应用层标识1是UE1的应用层标识，应用层标识2是UE2的应用层标识。
每个PC5链路中可以建立一个或者多个QoS flow，如图3示出的例子中，PC5链路1中建立有PC5QoS flow#1至PC5QoS flow#3。进一步的，每个PC5QoS flow由一个PC5QoS flow标识(PC5QoS flow identifier，PFI)识别，PC5QoS flow标识在PC5链路中唯一标识一个PC5QoS flow。D2D QoS支持GBR QoS flow和Non-GBR QoS flow。
PC5QoS参数包括PQI(PC5 5QI)、PC5流比特速率(PC5flow bit rate)和PC5链路聚合比特速率(PC5link aggregated bit rates)。其中，PQI是一种特殊的5QI，每一个PQI值与QoS特征值一一对应，QoS特征值包括资源类型，优先级级别，数据包时延预算，数据包错误概率，最大数据突发量，平均窗口。PC5流比特速率包括保证流比特速率和最大流比特速率，PC5QoS参数中内容均可参见上述5G QoS管理中相关解释。
对于D2D场景下QoS管理，终端设备在注册过程中可从PCF获取QoS映射配置，QoS映射配置包括在终端设备策略中。QoS映射配置包括：配置1)业务类型或业务需求(优先级、可靠性、时延等)与PC5QoS参数(如PQI，MFBR/GFBR等)的对应关系；配置2)PC5QoS参数与侧行链路无线承载(side link radio bear，SLRB)的对应关系。其中PC5QoS参数为网络授权的PC5QoS参数。其中，配置1)可用于终端设备在网络服务和不在网络服务下场景，配置2)可用于终端设备不在网络服务下场景。PCF在向终端设备提供授权的PC5QoS参数的同时，也将授权的PC5QoS参数通过AMF发送给终端设备所驻留的RAN。值得注意的是，发送给终端设备和RAN的PC5QoS参数都是用于终端设备间直接通信的PC5QoS参数。用于终端设备间直接通信的PC5QoS参数可以理解为该PC5QoS参数用于终端设备间直接通信的PC5链路。
终端设备间在建立链路或更新链路流程中，协商PC5QoS flow信息，建立PC5QoS flow。具有相同PC5QoS参数的不同业务关联到同一个PC5QoS flow中。对于每个PC5QoS flow，PC5QoS flow信息包括PC5QoS flow标识以及PC5QoS flow标识对应的PC5QoS参数信息。终端设备推导出QoS规则(QoS rule)，表示PC5数据包过滤集合(PC5Packet Filter Set)与PC5QoS flow标识的对应关系。PC5数据包过滤集合可以包括业务类型、源层2标识(Source layer-2identifier，Source L2ID)/目的层2标识(Destination layer-2identifier，Destination L2ID)、应用层ID的任意组合。PC5数据包过滤集合可以是IP数据包过滤集合，包括源/目的IP地址、源/目的端口号等任意组合。
终端设备协商PC5QoS参数信息之后，终端设备在网络服务下，终端设备向RAN提供PC5QoS参数信息和链路信息(如PC5链路标识(PC5link ID)或目的层2标识)，从而终端设备从RAN中获取PC5QoS参数对应的接入层(access stratum，AS)层配置(如逻辑信道配置或无线承载配置)。RAN根据从PCF获取的授权的PC5QoS参数对终端设备提供的PC5QoS参数进行授权，授权通过后再提供AS层配置。
3、PC5链路建立
在5G系统中，两个终端设备(可分别表示为UE1和UE2)之间建立PC5链路的流程示意图可参见图4所示，其中UE1和UE2之间建立的PC5链路可以是PC5单播链路。
步骤401，UE1发送直接通信请求消息。
该直接通信请求消息中包括UE2的应用层标识。具体地，UE1使用源层2标识和目的层2标识发送该直接通信请求消息，该直接通信请求消息可以为广播消息。其中，源层2 标识为UE1自己分配的层2地址，目的层2标识为广播的层2地址。在UE1发送直接通信请求消息之前，UE2确定用于接收直接通信请求消息的层2地址，将UE2的层2地址配置在UE2侧。
步骤402，UE1与UE2之间建立安全通道。
步骤403，UE2接收UE1广播的直接通信请求消息，确定直接通信请求消息中包括UE2的应用层标识，UE2响应于该直接通信请求消息，向UE1发送直接通信响应消息。示例性的，直接通信响应消息可以是直接通信接受消息。该直接通信响应消息对应的源层2标识为UE2自己分配的层2地址，目的层2标识为步骤401中UE1的层2地址。
可选的，在步骤401和步骤403中，UE1与UE2之间还可以协商PC5QoS flow信息，PC5QoS flow信息中可包括PC5QoS flow标识以及PC5QoS flow标识对应的PC5QoS参数信息。
步骤404，在UE1与UE2之间建立完成PC5链路之后，UE1与UE2之间可以相互传输业务数据，其中业务数据又可称为是侧行数据、侧行业务数据、或邻近业务(proximity-based services，ProSe)数据等。
需要指出的是，UE1和UE2还会分别分配PC5链路标识来标识该PC5链路，其中PC5链路标识是每个终端设备单独分配的，只在终端设备内部层间交互使用。以其中任一个终端设备，比如UE1为例，该UE1中包括ProSe层和AS层，ProSe层与另外一个终端设备(即UE2)建立完PC5链路后，ProSe层将PC5链路标识、该PC5链路使用的源层2标识及目的层2标识发送给AS层。AS层存储PC5链路标识、源层2标识及目的层2标识的对应关系。ProSe层建立完PC5QoS flow后，将PC5QoS flow标识和对应的PC5QoS参数发送到AS层，AS层保存PC5QoS flow标识对应的PC5QoS参数，根据PC5QoS参数生成AS层配置(如逻辑信道配置或无线承载配置)。
在UE1发送数据包时，ProSe层确定数据包对应的PC5链路标识和PC5QoS flow标识，向AS层随数据包携带有PC5链路标识和PC5QoS flow标识，AS层根据PC5链路标识确定源层2标识和目的层2标识，AS层根据PC5QoS flow标识确定AS层配置，AS层利用源层2标识和目的层2标识、AS层配置发送相应数据。在UE1接收数据包时，UE1的AS层可接收所有终端设备发送的数据包，确定目的层2标识是否为自己分配的L2ID，若是，则判断自己为数据的接收端，递交上层进一步处理；若否，则丢弃该数据包。
4、授权频谱、非授权频谱、频谱资源
授权频谱(licensed spectrum)：目前公众移动通信网均使用授权频谱，由各国电信或频率管理部门分配授权，在授权频谱范围内不允许其他技术和网络使用，以确保移动网络的质量和安全。通过授权频谱中的频谱资源传输业务可以保障业务的可靠性等需求。
非授权频谱(unlicensed spectrum)：非授权频谱的使用无需申请并且免费。其中，无线保真(wireless fidelity，WiFi)、紫蜂协议(zigbee)等技术使用的是非授权频谱。通过非授权频谱中的频谱资源传输业务时业务的可靠性等需求不易保障。在本申请中，非授权频谱又可以称为免授权频谱。
频谱资源(spectrum resource)：指传输无线电磁波所用的频率资源，可以是一段频谱资源或某些特定的频率资源。例如，授权频谱中的频谱资源可以是3500MHz-3600MHz共100MHz带宽中的频率资源，非授权频谱中的频谱资源可以是5.15GHz-5.35GHz共200MHz 带宽中的频率资源。
两个终端设备之间建立PC5链路之后，两个终端设备即可以通过侧行链路相互传输业务数据。本申请提供的通信方法可用于合理确定出频谱方式，从而该两个终端设备可以采用确定出的频谱方式传输业务数据。
本申请中，两个终端设备可分别是第一终端设备和第二终端设备，其中第一终端设备可以是业务数据的发送端，第二终端设备可以是业务数据的接收端。为方便描述，如下将第一终端设备简称为UE1，第二终端设备简称为UE2。
UE1与UE2传输的业务数据可称为是第一业务的业务数据；UE1与UE2传输第一业务的业务数据的频谱方式，可称为是第一频谱方式，第一频谱方式可以是授权频谱方式，或非授权频谱方式，或授权频谱和非授权频谱(licensed spectrum and unlicensed spectrum)方式。具体地，当第一频谱方式是授权频谱方式时，UE1与UE2可通过授权频谱传输第一业务的业务数据；当第一频谱方式是非授权频谱方式时，UE1与UE2可通过非授权频谱传输第一业务的业务数据；当第一频谱方式是授权频谱和非授权频谱方式时，UE1与UE2可通过授权频谱和非授权频谱传输第一业务的业务数据。示例性的，UE1可基于载波聚合(carrier aggregation，CA)方式，实现同时使用授权频谱和非授权频谱与UE2传输第一业务的业务数据。
图5示出了本申请的一种通信方法，在该通信方法中，UE1可根据第一业务的业务信息，与UE2采用第一频谱方式传输第一业务的业务数据，具体如下所述。
步骤501，UE1获取第一业务的业务信息。
可选的，在UE1的应用层发起第一业务的请求时，UE1的应用层可生成第一业务的业务信息，并将该第一业务的业务信息发送给UE1的ProSe层。相应的，UE1的ProSe层可从UE1的应用层获取第一业务的业务信息。
其中，第一业务的业务信息可以包括以下(1)至(3)中的至少一项：
(1)第一业务的PC5QoS参数
其中，第一业务的PC5QoS参数中可包括以下一项或多项：第一业务的PQI、或第一业务的比特速率。
(2)第一业务的业务类型
其中，第一业务的业务类型可包括以下一项或多项：视频、语音、或关键业务(critical service)、ProSe业务类型(ProSe service type)、服务商业务标识(provider service identifier，PSID)、或智能交通系统应用标识(intelligent transport systems application identifier，ITS-AID)。其中，ProSe业务类型可以用于标识业务类型为ProSe的业务。
(3)第一业务的业务标识
其中，第一业务的业务标识可以是，ProSe标识(ProSe identifier)，或者第一业务的流描述(traffic descriptor)。
其中，第一业务的流描述可以是，第一业务对应的IP描述(IP descriptor)，或域描述(domain descriptor)，其中域描述比如是全限定域名(fully qualified domain name，FQDN)。
步骤502，UE1根据第一业务的业务信息，采用第一频谱方式与UE2传输第一业务的业务数据。
其中，UE1与UE2传输第一业务的业务数据，可以理解为第一业务的业务数据承载于 UE1与UE2之间的侧行链路上。本申请中，UE1与UE2之间的侧行链路可以是PC5链路(PC5link)、或层2链路(Layer-2link)、或PC5单播链路(PC5unicast link)。
上述技术方案中，UE1可根据第一业务的业务信息，采用第一频谱方式与UE2传输第一业务的业务数据，如此，UE1和UE2之间可通过更适用于业务特征的频谱方式来传输业务数据，有助于更好地满足业务需求以及合理地利用授权频谱和非授权频谱。
可选地，在上述实施例的第一种实施场景下，上述方法还包括：UE1根据第一业务的业务信息，确定第一频谱方式。

优先授权频谱方式，可理解为，UE1与UE2可通过授权频谱方式，也可通过非授权频谱方式来传输业务数据，但优先通过授权频谱方式传输业务数据。示例性的，UE1可先确定是否通过授权频谱方式来传输业务数据，若是，则通过授权频谱方式来传输业务数据；否则，UE1可通过非授权频谱方式传输业务数据。其中，UE1确定是否通过授权频谱方式传输业务数据的实现方式，可参见下述实施例中描述。
优先非授权频谱方式，可理解为，UE1与UE2可通过非授权频谱方式，也可通过授权频谱方式传输业务数据，但优先通过非授权频谱方式传输业务数据。示例性的，UE1可先确定是否通过非授权频谱方式传输业务数据，若是，则通过非授权频谱方式传输业务数据；否则，UE1可通过授权频谱方式传输业务数据。其中，UE1确定是否通过非授权频谱方式传输业务数据的实现方式，可参见下述实施例中描述。

解释为，该对应关系中第一业务的业务信息对应于授权频谱方式、或非授权频谱方式、或授权频谱和非授权频谱方式，UE1可将对应关系中第一业务的业务信息对应的频谱方式，作为第一频谱方式。
结合表1中例子，第一业务的业务信息中包括PQI＝90，那么UE1可根据PQI＝90和对应关系，确定第一频谱方式为授权频谱方式；或者结合表2中例子，第一业务的业务信息中包括视频1，那么UE1可根据视频1和对应关系，确定第一频谱方式为非授权频谱方式；或者结合表3中例子，第一业务的业务信息中包括流描述1，那么UE1可根据流描述1和对应关系，确定第一频谱方式为授权频谱方式。
本申请中，UE1的ProSe层可从应用层获取第一业务的业务信息，以及获取业务信息与频谱方式的对应关系。在第一个具体实施场景中，UE1确定第一频谱方式可以由UE1的ProSe层或者AS层来实现，可参照如下两种方式：
方式一、ProSe层根据第一业务的业务信息和对应关系，确定第一频谱方式；
方式二、AS层从ProSe层获取第一业务的业务信息和对应关系，AS层根据第一业务的业务信息和对应关系，确定第一频谱方式。
在第二个具体实施场景中，UE1根据第一业务的业务信息与第二频谱方式的对应关系，以及第一业务的业务信息，确定第二频谱方式；UE1再根据第二频谱方式和第一信息，确定第一频谱方式。
解释为，该对应关系中第一业务的业务信息对应于优先授权频谱方式或优先非授权频谱方式，UE1可根据第一业务的业务信息和对应关系，确定出第二频谱方式，该第二频谱方式即为优先授权频谱方式或优先非授权频谱方式。
结合表1中例子，第一业务的业务信息中包括PQI＝91，那么UE1可根据PQI＝91和对应关系，确定第二频谱方式为优先授权频谱方式；或者结合表2中例子，第一业务的业务信息中包括视频2，那么UE1可根据视频2和对应关系，确定第二频谱方式为优先非授权频谱方式；或者结合表3中例子，第一业务的业务信息中包括流描述4，那么UE1可根据流描述4和对应关系，确定第二频谱方式为优先授权频谱方式。
进一步的，UE1可根据第二频谱方式和第一信息，确定第一频谱方式。
其中，第一信息中可包括以下(a)至(d)中的至少一项：
(a)授权频谱资源的使用状态：可包括授权频谱资源的使用率和/或空闲率；
(b)非授权频谱资源的使用状态：可包括非授权频谱资源的使用率和/或空闲率；
(c)建议的频谱方式：即网络设备(比如RAN或核心网设备)向UE1建议的频谱方式，其中建议的频谱方式可以是授权频谱方式、或非授权频谱方式、或授权频谱和非授权频谱方式中的一个或多个；或，
(d)授权的频谱方式：或称为允许的频谱方式，即网络设备(比如RAN或核心网设备)授权或者允许UE1使用的授权频谱方式，其中授权的频谱方式可以是授权频谱方式、 或非授权频谱方式、或授权频谱和非授权频谱方式中的一个或多个。
该方式中，UE1可以根据授权频谱资源的使用状态、非授权频谱资源的使用状态、建议的频谱方式、授权的频谱方式中的一项或多项，结合第二频谱方式，更灵活且合理地确定出第一频谱方式。
进一步的，UE可以通过如下两种可能方式获取第一信息：
可能方式1，UE1可接收来自网络设备的第一信息。
其中，第一信息中可包括以下(a)至(d)中的至少一项：(a)授权频谱资源的使用状态、(b)非授权频谱资源的使用状态、(c)建议的频谱方式、(d)授权的频谱方式。
具体地，UE1可接收来自网络设备的第一信息。该第一信息可以是UE1向网络设备请求之后获取的，或者是网络设备主动发送给UE1的。其中，网络设备可以是RAN或核心网设备，核心网设备比如是PCF。
具体可参见下述三个示例：
示例1，UE1可从RAN接收建议的频谱方式。一个具体实现中，RAN可根据UE1的服务小区中的授权频谱或非授权频谱资源的使用状态，确定建议的频谱方式，将建议的频谱方式发送给UE1。举例来说，RAN已知UE1的服务小区中，授权频谱资源的空闲率小于或等于第一空闲率阈值，RAN向UE1建议的频谱方式为非授权频谱方式；或者，RAN已知UE1的服务小区中，授权频谱资源的空闲率大于第一空闲率阈值，RAN向UE1建议的频谱方式为授权频谱方式。
示例2，UE1可从RAN接收授权频谱资源的使用状态，和/或，UE1可从RAN接收非授权频谱资源的使用状态。
示例3，UE1可从RAN或核心网设备接收授权的频谱方式。应理解，RAN或核心网设备还可指示UE1不能使用一种或多种频谱方式，比如RAN向UE1授权的频谱方式为授权频谱方式，即RAN向UE1指示UE1不能使用非授权频谱方式，或者不能使用授权频谱和非授权频谱方式。在另外的实现方式中，授权的频谱方式，也可以替换为，禁止的或非授权的频谱方式，如下均以授权的频谱方式为例说明。
可能方式2，UE1可监测资源池中的资源，以获取第一信息。
其中，第一信息中可包括以下(a)或(b)中的至少一项：(a)授权频谱资源的使用状态、(b)非授权频谱资源的使用状态。
具体可参见下述两个示例：
示例1，UE1可监测资源池中的授权频谱资源，得到授权频谱资源的使用率和/或空闲率。例如，资源池中包括10MHz的授权频谱资源，UE1监测有1MHz的授权频谱资源可以使用或空闲，UE1确定授权频谱资源的使用率为90％或授权频谱资源的空闲率为10％。
示例2，UE1可监测资源池中的非授权频谱资源，得到非授权频谱资源的使用率和/或空闲率。例如，资源池中包括50MHz的非授权频谱资源，UE1监测有10MHz的非授权频谱资源可以使用或空闲，UE1确定非授权频谱资源的使用率为40％或非授权频谱资源的空闲率为60％。
本申请中，UE1根据第二频谱方式和第一信息，确定第一频谱方式，至少有如下举例：
例子1，在第二频谱方式为优先授权频谱方式，且授权频谱资源的空闲率大于第一空闲率阈值的情况下，UE1确定第一频谱方式为授权频谱方式。
例子2，在第二频谱方式为优先非授权频谱方式、且非授权频谱资源的空闲率大于第 二空闲率阈值的情况下，UE1确定第一频谱方式为非授权频谱方式。
例子3，在第二频谱方式为优先授权频谱方式，且建议的频谱方式为授权频谱方式的情况下，UE1确定第一频谱方式为授权频谱方式。
例子4，在第二频谱方式为优先非授权频谱方式，且建议的频谱方式为非授权频谱方式的情况下，UE1确定第一频谱方式为非授权频谱方式。
例子5，在第二频谱方式为优先授权频谱方式，且授权的频谱方式为授权频谱方式的情况下，UE1确定第一频谱方式为授权频谱方式。
例子6，在第二频谱方式为优先非授权频谱方式，且授权的频谱方式为非授权频谱方式的情况下，UE1确定第一频谱方式为非授权频谱方式。
当然，本申请中还可能存在第二频谱方式与第一信息存在冲突的情况，可参见例子7至例子9。
例子7，第二频谱方式为优先授权频谱方式，但是建议的频谱方式为非授权频谱方式的情况下，UE1可比较二者的优先级，比如第二频谱方式的优先级高于建议的频谱方式的优先级，那么UE1可确定第一频谱方式为授权频谱方式。或者，以建议的频谱方式为准，那么UE1可确定第一频谱方式为非授权频谱方式。
例子8，第二频谱方式为优先授权频谱方式，但是授权的频谱方式为非授权频谱方式，UE1可确定第一频谱方式为非授权频谱方式。
例子9，第二频谱方式为优先授权频谱方式，但是授权频谱资源的空闲率小于或等于第一空闲率阈值的情况下，UE1可确定第一频谱方式为非授权频谱方式。
需要说明的是，上述例子1至例子9仅是示例性说明UE1如何根据第二频谱方式和第一信息确定第一频谱方式，本申请还有其他的实现方式，此处不再赘述。
本申请中，UE1的ProSe层可从应用层获取第一业务的业务信息，以及获取业务信息与频谱方式的对应关系。UE1的AS层可从RAN或核心网设备接收第一信息，或者监测资源池中非授权频谱资源和/或授权频谱资源，得到第一信息。
在第二个具体实施场景中，确定第一频谱方式具体可以由UE1的ProSe层或AS层来实现，可参照如下三种方式：
方式一、ProSe层根据第一业务的业务信息和对应关系，确定第二频谱方式；AS层从ProSe层中获取第二频谱方式，AS层根据第二频谱方式和第一信息，确定第一频谱方式；
方式二、ProSe层根据第一业务的业务信息和对应关系，确定第二频谱方式；ProSe层从AS层中获取第一信息，ProSe层根据第二频谱方式和第一信息，确定第一频谱方式；
方式三、AS层从ProSe层中获取第一业务的业务信息和对应关系，AS层根据第一业务的业务信息和对应关系，确定第二频谱方式；AS层根据第二频谱方式和第一信息，确定第一频谱方式。
可选地，在上述实施例的第二种实施场景下，UE1可以在获取到第一业务的业务信息之后，即可采用第一频谱方式向UE2传输第一业务的业务数据(而无需根据第一业务的业务信息，确定第一频谱方式)。在该实施场景中，第一业务的业务信息可以是第一业务的业务标识，比如业务标识1与授权频谱方式绑定，业务标识2与非授权频谱方式绑定，业务标识3与授权频谱和非授权频谱方式绑定。如此，UE1若需要发送某个业务的业务数据时，直接根据与业务绑定的频谱方式向UE2传输业务数据，比如第一业务的业务标识为业务标识1，那么UE1采用授权频谱方式与UE2传输第一业务的业务数据。
可选地，在上述实施例的第三种实施场景下，上述方法还包括：UE1向UE2发送第二信息；其中，第二信息用于指示UE1采用第一频谱方式传输第一业务的业务数据。
基于第二信息中携带的不同信息，可以有如下两个可能示例：
在第1个可能示例中，第二信息中包括第一频谱方式的标识，UE1向UE2发送第二信息和第一业务的业务标识，相应的，UE2可根据第二信息中包括的第一频谱方式的标识，以及第一业务的业务标识，采用第一频谱方式传输第一业务的业务数据。
在第2个可能示例中，第二信息中包括第一业务的业务标识和第一频谱方式的标识，UE1向UE2发送第二信息，相应的，UE2可根据第二信息中包括的第一业务的业务标识和第一频谱方式的标识，采用第一频谱方式传输第一业务的业务数据。
第二信息可以承载在PC5信令消息中，该PC5信令消息可通过UE1与UE2之间的侧行链路进行传输。如下以第2个可能示例解释说明：
第二信息可以是一个通知消息，该通知消息可用于通知UE2：UE1通过第一频谱方式与UE2传输第一业务的业务数据。
或者，第二信息还可以是一个请求消息，该请求消息可用于UE1向UE2请求：是否可通过第一频谱方式传输第一业务的业务数据。UE2接收到该请求消息之后，向UE1发送响应消息，该响应消息可以是接受响应或拒绝响应。
其中接受响应可用于指示UE2接受通过第一频谱方式与UE1传输业务数据；拒绝响应可用于指示UE2拒绝通过第一频谱方式与UE1传输业务数据。示例性的，该响应消息可以是1个比特，比如该1比特取值为1时表示接受响应，该1比特取值为0时表示拒绝响应。示例性的，该请求消息或响应消息均可以是PC5信令消息，该PC5信令消息通过UE1与UE2之间的侧行链路进行传输，请求消息如直接通信请求(direct communication ruqest)消息，响应消息如直接通信接受(direct communication accept)消息。
在一种可能方式中，UE2也可以根据该第一业务的业务信息和对应关系，确定用于传输第一业务的业务数据的频谱方式(可称为第三频谱方式)。UE2可根据第三频谱方式，以及请求消息中第一频谱方式的标识和第一业务的业务标识，确定是否通过第一频谱方式与UE1传输第一业务的业务数据，然后UE2再向UE1发送拒绝响应或接受响应。
此处可以理解，UE2中也可以预先配置有业务信息与频谱方式的对应关系，UE2中预配置的对应关系与UE1中预配置的对应关系可以相同或不同，相应的，UE2确定出的第三频谱方式与UE1指示的第一频谱方式可以相同或不同。举例来说，UE1确定的第一频谱方式为授权频谱方式，UE2确定的第三频谱方式同样为授权频谱方式。UE1向UE2发送请求消息，UE2根据请求消息中的第一频谱方式的标识和第一业务的业务标识，确定第三频谱方式与第一频谱方式相同，UE2向UE1发送接受响应。
此外，UE2向UE1发送的响应消息中也可以包括第三频谱方式的标识，从而UE2可告知UE1当前UE2可通过第三频谱方式与UE1传输第一业务的业务数据。举例来说，UE1确定的第一频谱方式为授权频谱方式，UE2确定的第三频谱方式同样为授权频谱方式。UE1可向UE2发送请求消息，该请求消息中包括第一业务的业务标识和第一频谱方式的标识，其中第一频谱方式的标识用于指示授权频谱方式。UE2在接收到该请求消息之后向UE1发送响应消息，该响应消息中包括第一业务的业务标识和第三频谱方式的标识，第三频谱方式的标识同样用于指示授权频谱方式。相应的，UE1根据响应消息确定UE2可通过第一频谱方式(即授权频谱方式)与UE1传输第一业务的业务数据。
需要补充的是，在第一频谱方式是非授权频谱方式，或者为授权频谱和非授权频谱方式的情况下，UE1不仅可以向UE2发送第二信息，还可向UE2发送第一非授权频谱资源的信息，该第一非授权频谱资源的信息可用于指示UE1与UE2通过第一非授权频谱资源传输第一业务的业务数据。相应的，UE2接收到第二信息之后，可以收听该第一非授权频谱资源，以接收来自于UE1的第一业务的业务数据。
在该实现方式中，非授权频谱可以包括多个非授权频段，UE1可以从多个非授权频段中选择其中一个非授权频段，UE1向UE2发送该非授权频段的标识或编号，该非授权频段即为第一非授权频谱资源，该非授权频段的标识或编号即为第一非授权频谱资源的信息。举例来说，非授权频谱中包括非授权频段1(比如5.15GHz-5.35GHz)，和非授权频段2(比如5.725GHz-5.85GHz)，UE1可选择非授权频段1作为第一非授权频谱资源，然后UE1向UE2发送该非授权频段1的标识或编号。
UE1在从多个非授权频段中选择其中一个非授权频段的过程中，UE1可以从多个非授权频段中随机选择一个；或者UE1获取每个非授权频段中频谱资源的使用率和/或空闲率，从中选择一个使用率相对较低或空闲率相对较高的非授权频段。在另外的示例中，UE1还可以从非授权频谱的多个非授权频段中，确定第一非授权频谱资源的资源位置，将该第一非授权频谱资源的资源位置发送至UE2。此外，UE1也可以向UE2发送第一非授权频谱资源的信息，而无需向UE2发送第二信息，相应的，UE2根据该第一非授权频谱资源的信息，接收来自于UE1的第一业务的业务数据。
如此，UE2可以仅收听第一非授权频谱资源上是否有第一业务的业务数据，而无需收听所有非授权频谱上的资源，从而有助于减少UE2的能耗。
此外，UE1与UE2之间的侧行链路中可包括多个QoS flow，UE1与UE2之间传输的业务数据可承载于侧行链路中的某一个QoS flow(可以记为第一QoS flow)中。在此种情况下，UE1与UE2之间采用第一频谱方式传输第一业务的业务数据，可以理解为：UE1与UE2在侧行链路中采用第一频谱方式传输第一QoS flow，其中该第一QoS flow中承载有第一业务的业务数据。如此，UE1与UE2之间的多个QoS flow中可分别承载有不同业务信息对应的业务数据，且不同QoS flow可对应于不同的频谱方式，从而助于提高业务数据传输的灵活性。
在该实现方式中，UE1可根据第一频谱方式和第一QoS flow对应的频谱方式，将第一业务关联到第一QoS flow，从而在UE1向UE2发送第一业务的业务数据时，可将第一业务的业务数据承载于第一QoS flow中。
其中，UE1将第一业务关联到第一QoS flow，具体可以有如下两种可能方式：
预先说明的是，UE1与UE2的侧行链路中包括的QoS flow可对应于各自的频谱方式，比如某个QoS flow对应于授权频谱方式，或对应于非授权频谱方式，或对应于授权频谱和非授权频谱方式。QoS flow对应的频谱方式表示使用该频谱方式传输该QoS flow。例如，QoS flow对应的频谱方式为授权频谱方式，则使用授权频谱方式传输该QoS flow。
可能方式一，UE1可以先根据第一频谱方式，以及侧行链路中多个QoS flow分别对应的频谱方式，确定侧行链路中包括的多个QoS flow中是否存在与第一频谱方式相对应(或相关联)的QoS flow。若存在，则从中选择出与第一频谱方式相对应的QoS flow作为第一QoS flow；若不存在，则根据第一频谱方式，生成一个新的QoS flow，该新的QoS flow与第一频谱方式相对应，该新的QoS flow即为第一QoS flow。然后UE1将第一业务关联至 该第一QoS flow。
可能方式二，UE1可根据第一频谱方式，生成第一QoS flow，其中第一QoS flow与第一频谱方式相对应(或相关联)。然后UE1将第一业务关联至该第一QoS flow。
本申请中，第一QoS flow与第一频谱方式相对应，可以有如下两种示例：
一个示例中，第一QoS flow对应的频谱方式与第一频谱方式相同，比如第一QoS flow对应的频谱方式为授权频谱方式，第一频谱方式同样为授权频谱方式；或者，第一QoS flow对应的频谱方式为非授权频谱方式，第一频谱方式同样为非授权频谱方式；又或者，第一QoS flow对应的频谱方式为授权频谱和非授权频谱方式，第一频谱方式同样为授权频谱和非授权频谱方式，等等，UE1可以确定第一QoS flow与第一频谱方式相对应。
再一个示例中，第一QoS flow对应的频谱方式中包括第一频谱方式，比如第一QoS flow对应的频谱方式为授权频谱和非授权频谱方式，第一频谱方式为授权频谱方式；或者，第一QoS flow对应的频谱方式为授权频谱和非授权频谱方式，第一频谱方式为非授权频谱方式，UE1可以确定第一QoS flow与第一频谱方式相对应。
进一步需要说明的是，第一QoS flow不仅与第一频谱方式相对应，该第一QoS flow还需要满足第一业务的PC5QoS参数。
当第一业务的业务信息中包括第一业务的PC5QoS参数的情况下，UE1可以先根据第一业务的PC5QoS参数和对应关系确定第一频谱方式，然后从侧行链路中选择与第一频谱方式相对应、且满足第一业务的PC5QoS参数的QoS flow，作为第一QoS flow。
进一步的，UE1可以将对应于相同PC5QoS参数的业务关联至同一个QoS flow中，也可理解，不同业务若对应于相同的PC5QoS参数，那么该不同业务可以关联至同一个QoS flow中，该同一个QoS flow中可承载该不同业务分别对应的业务数据。
当第一业务的业务信息中包括第一业务的业务类型的情况下，UE1可以先根据第一业务的业务类型和对应关系确定第一频谱方式，然后从侧行链路中选择与第一频谱方式相对应、且满足第一业务的PC5QoS参数的QoS flow，作为第一QoS flow。
进一步的，不同类型的业务在对应于相同PC5QoS参数的情况下，也可能会对应于不同的第一频谱方式，即可能关联至不同的QoS flow中，也可理解，能够关联到同一个QoS flow的不同业务既要PC5QoS参数相同，又要业务类型与频谱方式的对应关系相同。
在该可能方式中，第二信息中可包括第一频谱方式的标识，UE1向UE2发送第二信息和第一QoS flow的标识，相应的，UE2可根据第二信息中包括的第一频谱方式的标识，以及第一QoS flow的标识，采用第一频谱方式传输第一QoS flow。又或者，第二信息中包括第一QoS flow的标识和第一频谱方式的标识，UE1向UE2发送第二信息，相应的，UE2可根据第二信息中包括的第一QoS flow的标识和第一频谱方式的标识，采用第一频谱方式传输第一QoS flow。进一步的，第一QoS flow具体可以是PC5QoS flow。
可选的，在步骤502中，UE1采用第一频谱方式与UE2传输第一业务的业务数据，具体可以是，UE1向RAN请求第一频谱方式对应的频谱资源，然后UE1根据请求到的频谱资源向UE2发送第一业务的业务数据；或者还可以是，UE1收听抢占第一频谱方式对应的频谱资源，然后UE1根据收听抢占的频谱资源向UE2发送第一业务的业务数据。相应的，UE2可以在第一频谱方式对应的频谱资源上进行检测，以接收到来自于UE1的第一业务的业务数据。如下示例性说明UE1采用第一频谱方式与UE2传输第一业务的业务数据的两种实现方式：
实现方式1，在第一频谱方式为授权频谱方式的情况下，UE1向RAN发送资源请求信息，该资源请求信息用于请求UE1与UE2之间传输第一业务的业务数据的授权频谱资源。相应的，RAN根据该资源请求信息，向UE1分配授权频谱资源，并将授权频谱资源的资源位置(如时频资源位置信息)指示给UE1。UE1在该资源位置对应的授权频谱资源上，向UE2发送第一业务的业务数据。在该实现方式中，若UE1向RAN请求授权频谱资源失败，RAN还可以向UE1分配非授权频谱资源，UE1基于RAN分配的非授权频谱资源，与UE2传输第一业务的业务数据。
实现方式2，在第一频谱方式为非授权频谱方式的情况下，UE1收听抢占资源池中的非授权频谱资源，确定出用于传输第一业务的业务数据的非授权频谱资源的资源位置。UE1在该资源位置对应的非授权频谱资源上，与UE2传输第一业务的业务数据。
可选的，在步骤502之前，UE1还可以向RAN发送PC5QoS参数和链路信息，其中链路信息比如是PC5链路标识或目的层2标识。RAN根据PC5QoS参数和链路信息，向UE1发送AS层配置。具体地，RAN根据从PCF中获取的授权的PC5QoS参数对UE提供的PC5QoS参数进行授权，授权通过后向UE1发送PC5QoS参数和链路信息对应的AS层配置。在该步骤中，UE1还可向RAN发送第一频谱方式的标识，RAN根据该第一频谱方式的标识判断是否预留用于UE1与UE2传输第一业务的业务数据的授权频谱资源或非授权频谱资源。
为了更好地解释本申请实施例，图6为本申请示例性提供的一种具体应用场景下的UE1与UE2传输第一业务的业务数据的实现方式。
步骤601，UE1向PCF发送5G邻近服务能力。具体地，UE1在注册流程中通过AMF向PCF发送5G邻近服务能力。
步骤602，PCF向UE1发送业务信息与频谱方式的对应关系。具体地，PCF通过AMF向UE1发送业务信息与频谱方式的对应关系。

示例性的，UE1根据业务信息与频谱方式的对应关系，以及第一业务的业务信息确定第一频谱方式。
再示例性的，UE1根据业务信息与频谱方式的对应关系，以及第一业务的业务信息确定第二频谱方式；UE1再根据第二频谱方式和第一信息，确定第一频谱方式。
步骤605，UE1向UE2发送请求消息，请求消息中包括第一QoS flow的标识和第一频谱方式的标识。
步骤606，UE2响应于UE1的请求消息，向UE1发送响应消息，响应消息中包括第一QoS flow的标识和第一频谱方式的标识。可以理解，该响应消息用于指示UE2接受通过第一频谱方式与UE1传输第一QoS flow。
步骤607，UE1向RAN发送信息报告，信息报告中包括第一频谱方式的标识、PC5QoS参数和链路信息，其中链路信息比如是PC5链路标识或目的层2标识。RAN中存储第一频谱方式的标识、PC5QoS参数和链路信息。
步骤608，RAN向UE1发送AS层配置。
步骤609，UE1采用第一频谱方式与UE2传输第一QoS flow，其中该第一QoS flow中承载有第一业务的业务数据。
需要指出的是，步骤603为可选步骤，在业务信息与频谱方式的对应关系中，若第一业务的业务信息与第二频谱方式相对应，则RAN可向UE1发送第一信息。
此外，在步骤602中，PCF还可向UE1发送该UE1的授权的频谱方式，具体地，在业务信息与频谱方式的对应关系中，若第一业务的业务信息与第二频谱方式相对应，则PCF可向UE1发送该UE1的授权的频谱方式，其中该授权的频谱方式即第一信息。该第一信息用于UE1在步骤604中确定第一频谱方式。

图10示出了本申请的另一种通信方法，在该通信方法中，UE1可根据UE1签约的频谱方式，与UE2采用第一频谱方式传输第一业务的业务数据，具体如下所述。
步骤1001，UE1获取UE1签约的频谱方式。
UE1签约的频谱方式可包括如下频谱方式中的一个或多个：授权频谱方式、非授权频谱方式、优先授权频谱方式、优先非授权频谱方式、或授权频谱和非授权频谱方式。
其中签约的频谱方式也可理解为授权的频谱方式，即UE1可获取网络设备授权给UE1(或网络设备允许UE1使用)的频谱方式。
进一步的，UE1还可获取UE1签约的频谱方式对应的区域信息，可以理解，UE在不同区域时可使用的频谱方式不同，比如授权频谱方式对应于区域1，UE1在区域1中使用授权频谱方式；非授权频谱方式对应于区域2，UE1在区域2中使用非授权频谱方式等。
在一种可能方式中，UE1签约的频谱方式可以是UE1从PCF接收的。示例性的，在注册过程中，UE1向AMF发送5G邻近服务能力，AMF将5G邻近服务能力转给PCF。PCF响应于该5G邻近服务能力，向UE1发送UE1签约的频谱方式。其中，UE1签约的频谱方式可以是PCF生成的，或者是PCF从UDR或者AF中获取的。在另外的实现方式中，UE1签约的频谱方式还可以是UE从UDM中获取，或者是UE1预配置的。UE1还可以通过上述的任一种方式获取UE1签约的频谱方式对应的区域信息，不再赘述。
步骤1002，UE1根据UE1签约的频谱方式，采用第一频谱方式与UE2传输第一业务的业务数据。
上述技术方案中，UE1和UE2之间可通过更适用于UE1特征的频谱方式来传输该业务数据，有助于更好地传输业务数据以及合理地利用授权频谱和非授权频谱。
可选地，在上述实施例的第1种实施场景下，上述方法还包括：UE1根据UE1签约的频谱方式，确定第一频谱方式。如下分两种情况说明：
在UE1签约一个频谱方式的情况中：
若UE1签约授权频谱方式、或签约非授权频谱方式、或签约授权频谱和非授权频谱方式，UE1可将UE1签约频谱方式确定为第一频谱方式。比如UE1签约授权频谱方式，那么UE1可确定授权频谱方式为第一频谱方式。
若UE1签约优先授权频谱方式、或签约优先非授权频谱方式(即第二频谱方式)，UE1可根据第二频谱方式和第一信息，确定第一频谱方式。比如，UE1签约优先授权频谱方式(即第二频谱方式)，第一信息中包括的授权频谱资源的空闲率大于第一空闲率阈值，UE1可根据授权频谱资源的空闲率和优先授权频谱方式，选择授权频谱方式(即第一频谱方式)。
在UE1签约多个频谱方式的情况中：
UE1可从UE1签约的多个频谱方式中确定出第一频谱方式。具体可以有如下两个示例：
在一个示例中，UE1可根据第一区域信息，以及UE1签约的频谱方式对应的区域信息，从UE1签约的多个频谱方式中确定出第一频谱方式。第一区域信息可用于表征UE1所在的区域。UE1可根据UE1所在的区域确定第一区域信息，或UE1从RAN接收第一区域信息。如此，UE1可更好地确定出与UE1所在区域相适应的第一频谱方式。
进一步的，频谱方式对应的区域信息可以是小区粒度的，频谱方式对应的区域信息可包括一个或多个小区；或者，频谱方式对应的区域信息还可以是跟踪区(tracking area，TA)粒度的，频谱方式对应的区域信息可包括一个或多个TA。
第一区域信息可以是小区粒度的，第一区域信息可用于指示UE1处于哪个小区；或者，第一区域信息还可以TA粒度的，第一区域信息可用于指示UE1处于哪个TA。
举例来说，UE1可以签约授权频谱方式、非授权频谱方式、授权频谱和非授权频谱方式中的多个，比如授权频谱方式对应于TA#1，非授权频谱方式对应于TA#2，授权频谱方式和非授权频谱方式对应于TA#3。UE1可根据UE1所处区域确定第一区域信息，比如第一区域信息为TA#1，UE1可根据第一区域信息(即TA#1)，以及UE1签约的频谱方式对应的区域信息，选择授权频谱方式(即第一频谱方式)。再比如，第一区域信息为小区#1，该小区#1属于TA#1，则UE1可根据第一区域信息(即小区#1)和UE1签约的频谱方式对应的区域信息，选择授权频谱方式(即第一频谱方式)。
在上述例子中，UE1还可以签约优先授权频谱方式和优先非授权频谱方式，比如优先授权频谱方式对应于TA#4，优先非授权频谱方式对应于TA#5，UE1还可根据UE1所处区域确定第一区域信息，比如第一区域信息指示TA#4，则UE1可根据第一区域信息和UE1签约的频谱方式对应的区域信息，选择优先授权频谱方式(即第二频谱方式)。在该情况中，UE1还可进一步根据第二频谱方式和第一信息，确定第一频谱方式。
当然，UE1还可签约授权频谱方式、非授权频谱方式、授权频谱和非授权频谱方式中的一个或多个，以及签约优先授权频谱方式和优先非授权频谱方式中的一个或多个，UE1从该签约的频谱方式中确定第一频谱方式的实现方式与上述类似。
在另一个示例中，UE1从UE签约的频谱方式中随机确定一个频谱方式，该确定出的频谱方式可以是第一频谱方式或第二频谱方式。在该确定出的频谱方式为第二频谱方式的 情况下，UE1可以根据第二频谱方式和第一信息，进一步确定第一频谱方式。
随后，UE1可采用确定出的第一频谱方式，与UE2传输第一业务的业务数据。
进一步的，UE1的ProSe层可获取UE1签约的频谱方式。AS层可从RAN或核心网设备接收第一信息，或者监测资源池中非授权频谱资源和/或授权频谱资源，得到第一信息。
确定第一频谱方式具体可以由UE1的ProSe层或AS层来实现，可参照如下五种方式：
方式1、ProSe层根据UE1签约的频谱方式、UE1签约的频谱方式对应的区域信息以及第一区域信息，确定第一频谱方式；其中，第一区域信息可以是AS层从RAN接收的，或者，AS层根据UE1所处的区域确定的，相应的，ProSe层可从AS层获取第一区域信息。或者在其他示例中，第一区域信息可以是ProSe层根据UE1所处区域确定的。
方式2、AS层接收来自于ProSe层的UE1签约的频谱方式、UE1签约的频谱方式对应的区域信息，AS层根据UE1签约的频谱方式、UE1签约的频谱方式对应的区域信息以及第一区域信息，确定第一频谱方式；其中第一区域信息可以是AS层从RAN接收的，或者，AS层根据UE1所处的区域确定的；或者在其他示例中，第一区域信息可以是ProSe层根据UE1所处区域确定的，相应的，第一区域信息可以是AS层从ProSe层获取。
方式3、ProSe层根据UE1签约的频谱方式，确定第二频谱方式；AS层接收来自于ProSe层的第二频谱方式，根据第二频谱方式和第一信息，确定第一频谱方式。
方式4、ProSe层根据UE1签约的频谱方式，确定第二频谱方式；ProSe层从AS层中接收第一信息，ProSe层根据第二频谱方式和第一信息，确定第一频谱方式。
方式5、AS层接收来自于ProSe层的UE1签约的频谱方式，AS层根据UE1签约的频谱方式，确定第二频谱方式；AS层根据第二频谱方式和第一信息，确定第一频谱方式。
本申请实施例中，第一信息、UE1获取第一信息、以及UE1根据第二频谱方式和第一信息确定第一频谱方式的具体说明，均可参见上述步骤502中关于确定第一频谱方式的实现方式中的描述，不再赘述。
可选地，在上述实施例的第2种实施场景下，若UE1签约一个频谱方式，且该签约的一个频谱方式为授权频谱方式、或非授权频谱方式、或授权频谱和非授权频谱方式，那么UE1可直接采用UE1签约的一个频谱方式，与UE2传输第一业务的业务数据。
可选地，上述方法还包括：UE1向UE2发送第二信息，第二信息用于指示UE1采用第一频谱方式传输第一业务的业务数据，具体可参见步骤502中关于第二信息的描述。
需要补充的是，在第一频谱方式是非授权频谱方式，或者为授权频谱和非授权频谱方式的情况下，UE1不仅可以向UE2发送第二信息，还可向UE2发送第一非授权频谱资源的信息，具体可参见步骤502中关于第一非授权频谱资源的信息的描述。
此外，UE1还可将第一频谱方式与UE1与UE2之间的侧行链路绑定，即UE1与UE2之间通过侧行链路传输第一业务的业务数据，且该侧行链路可占用第一频谱方式对应的频谱资源。一个具体是实现中，UE1通过UE1和UE2之间的侧行链路向UE2发送第二信息，第二信息中包括第一频谱方式的标识，相应的，UE2可根据第二信息中包括的第一频谱方式的标识，将UE1与UE2之间的侧行链路与第一频谱方式绑定。
本申请实施中，UE1可以通过第一频谱方式对应的频谱资源，与UE2传输侧行链路中的业务数据，也可以理解，该侧行链路中可包括一个或多个QoS flow，该一个或多个QoS flow均可通过第一频谱方式对应的频谱资源传输。
