下面结合说明书附图对本申请实施例做进一步详细描述。
如图1所示，本申请实施例提供一种资源分配的方法，该方法包括：
步骤100：针对任意一个直接通信业务对应的逻辑信道，负责直接通信接口资源分配的协议层生成与所述逻辑信道对应的候选频带资源集合；

其中，本申请实施例中针对不同情况设定了不同的资源分配模式，并提供了两种分配模式，分别是网络调度的资源分配模式和终端自选的资源分配模式。
在“网络调度的资源分配模式”下主要指网络侧设备中的协议层生成该直接通信业务对应的逻辑信道对应的候选资源集合，并将确定的资源向与其进行直接通信的终端进行发送，所述终端在收到确定的资源后，执行直接通信接口数据发送。
而在“终端自选的资源分配模式”下主要指终端设备中的协议层生成该直接通信业务对应的逻辑信道对应的候选资源集合，并根据其确定的资源执行直接通信接口数据发送。
下面对两种模式分别进行介绍。
资源分配模式1：网络调度的资源分配模式。
具体的，对于网络调度的资源分配模式，所述协议层是指网络侧设备的MAC层。
也就是在进行直接通信业务对应的逻辑信道时，终端向网络侧设备发送辅助信息；协议层根据辅助信息生成与所述逻辑信道对应的候选频带资源集合，并从所述候选频带资源集合中为所述直接通信业务对应的逻辑信道分配使用的具体资源，并向终端发送包含指示信息的调度信息；终端根据指示信息确定对应的具体资源，并通过确定的资源传输所述直接通信业务对应的逻辑信道的数据。
以V2X业务为例，MAC层执行频带资源选择，生成与所述逻辑信道对 应的候选频带资源集合。然后MAC层根据终端对候选频带资源列表内的频带资源的测量结果确定该V2X业务在直接通信接口传输使用的具体资源。可选的，协议层根据如下信息之一或者组合确定所述直接通信业务对应的逻辑信道对应的候选频带资源集合：
直接通信业务对应的逻辑信道和SCS的对应关系；
各个频带资源和SCS的对应关系；
直接通信终端的能力信息；
高层配置的直接通信业务和频带资源的对应关系。
其中，对于直接通信业务对应的逻辑信道和SCS的对应关系来说，协议层若想通过直接通信业务对应的逻辑信道和子载波间隔SCS的对应关系确定所述直接通信业务对应的逻辑信道对应的候选频带资源集合，则所述网络侧设备中的协议层需要先确定所述直接通信业务对应的逻辑信道和SCS的对应关系。
具体的，所述协议层基于直接通信业务对应的逻辑信道的QoS参数确定直接通信业务对应的逻辑信道和SCS的对应关系；或，
所述协议层通过高层配置确定直接通信业务对应的逻辑信道和SCS的对应关系。
其中，所述生成与所述逻辑信道对应的候选频带资源集合中的资源集合可以有多种表现方式，例如生成与所述逻辑信道对应的候选频带资源集合中的资源列表，生成与所述逻辑信道对应的候选频带资源集合中的资源文件等。
需要说明的是，上面对资源集合的列举的方式只是举例说明，任何能够表示资源集合的方式都适用本申请实施例。
同时，在所述协议层生成与所述逻辑信道对应的候选频带资源集合后，需要从所述候选频带资源集合中为所述直接通信业务对应的逻辑信道分配使用的具体资源。
具体的，所述协议层根据所述直接通信业务对应的逻辑信道的数据量和/或直接通信终端对候选频带资源集合中的候选频带的测量结果，从所述候选 频带资源集合中为所述直接通信业务对应的逻辑信道分配具体使用的资源。
相应的，对于网络调度的资源分配模式下，所述协议层从所述候选频带资源集合中确定为所述直接通信业务对应的逻辑信道分配使用的具体资源后，通过向终端发送直接通信接口的调度信令，将所述确定的具体资源通知给所述终端。所述调度信令中通过携带资源指示信息，从而向终端指示直接通信接口使用的具体资源。

下面结合说明书附图对本申请实施例中一种资源分配的方法做进一步详细描述，其中分别选取网络调度资源分配模式下和终端自选的资源分配模式下直接通信接口资源的分配情景下进行举例说明。
实施例1：网络调度资源分配模式。
其中，网络调度资源分配模式下直接通信接口资源分配过程示意图如图4 所示，关于各个步骤的说明如下：
步骤1：网络侧设备确定各个频带资源使用的SCS通知。
其中，确定各个频带上频带资源使用的SCS通知有两种，具体如下：
确定方式1：基于网络实现确定各个频带资源使用的SCS。
确定方式2：协议约定或者预配置各个频带资源使用的SCS。
对于确定方式1,网络设备需要将频带资源使用的SCS通过并通过广播(复用现有SIB或者引入新的SIB)或者专用信令(包括RRC信令、MAC层信令或者物理层信令)通知终端。
对于确定方式2，通知过程可以省略。因此步骤1是可选步骤。

所述辅助信息的内容可以是但不限于如下之一或者组合：

步骤3：网络侧设备根据终端上报的辅助信息执行直接通信接口资源分配。
具体步骤如下：
(1)可用频带资源选择。
可选步骤。如果直接通信业务对应的逻辑信道和可用频带资源有对应关系，才需要执行本步骤。否则略过本步骤。
根据高层配置或者协议约定的直接通信业务对应的逻辑信道和可用频带资源的对应关系(高层配置来自步骤2终端上报的辅助信息或者网络设备通过和ProSe相关服务器交互直接获得)确定可用频带资源。
(2)频带资源选择。
网络设备的MAC执行频带资源选择，生成候选频带资源列表。
这个步骤中，考虑的因素包括但不限于如下之一或者组合：
直接通信业务对应的逻辑信道和SCS的对应关系；
直接通信终端的能力信息。
比如，如果直接通信终端能力很强，可以支持所有频带，那么只需要根据直接通信业务对应的逻辑信道和SCS的对应关系确定候选频带资源列表。否则，还需要考虑终端的能力信息，比如终端支持哪些SCS或者哪些频带组合。
其中，直接通信业务对应的逻辑信道和SCS的对应关系确定方式可以采用但不限于如下方式之一：
确定方式1：基于V2X业务的QoS参数确定V2X业务和SCS的对应关系。
比如PPPR或者时延参数等。
确定方式2：高层配置V2X业务和SCS的对应关系，所述高层指的是非接入层，比如SA2定义的ProSe相关协议层。
网络设备的MAC层通过直接通信业务对应的逻辑信道和SCS对应关系以及SCS和频带资源的对应关系就可以确定在步骤(1)确定的可用频带上哪些频带资源可以作为所述直接通信业务对应的逻辑信道的候选频带资源。
MAC层根据终端对候选频带资源列表内的频带资源的测量结果确定该直接通信业务对应的逻辑信道在直接通信接口传输使用的频带资源。
(3)具体资源选择。
网络设备在所选择的频带资源上进一步为终端每个直接通信业务对应的逻辑信道分配资源，综合考虑该直接通信终端每个直接通信业务对应的逻辑信道的资源分配情况，确定出针对该直接通信终端的总的资源分配信息。

(5)直接通信终端对直接通信接口资源调度信息进行处理。
直接通信终端基于接收到的直接通信接口资源分配信息确定各个直接通信业务对应的逻辑信道使用的资源。
(6)直接通信接口数据发送。
根据步骤(5)中确定的各个直接通信业务对应的逻辑信道使用的资源进行直接通信接口数据的发送。
实施例2：终端自选的资源分配模式。
其中，终端自选的资源分配模式下直接通信接口资源分配过程示意图如图5所示，关于各个步骤的说明如下：

其中，确定各个频带上频带资源使用的SCS有两种方法，具体如下：
确定方式1：基于网络实现确定各个频带资源使用的SCS。
确定方式2：协议约定或者预配置各个频带资源使用的SCS。
对于确定方式1,网络设备需要将频带资源/SCS对应关系通过并通过广播(复用现有SIB或者引入新的SIB)或者专用信令(包括RRC信令、MAC层信令或者物理层信令)通知终端。
对于确定方式2，通知过程可以省略。因此步骤1是可选步骤。
步骤2：终端执行直接通信接口资源分配。
其中，终端针对每个直接通信业务对应的逻辑信道进行直接通信接口资 源分配，具体资源分配步骤如下：
(1)可用频带资源选择。
可选步骤。如果直接通信业务对应的逻辑信道和可用频带资源有对应关系，才需要执行本步骤。否则略过本步骤。
(2)根据高层配置或者协议约定的直接通信业务对应的逻辑信道和可用频带资源的对应关系确定可用频带资源。
直接通信终端的MAC执行频带资源选择，生成候选频带资源列表。
这个步骤中，考虑的因素包括但不限于如下之一或者组合：
直接通信业务对应的逻辑信道和SCS的对应关系；
直接通信终端的能力信息。
比如，如果直接通信终端能力很强，可以支持所有频带，那么只需要根据直接通信业务对应的逻辑信道和SCS的对应关系确定候选频带资源列表。否则，还需要考虑终端的能力信息，比如终端支持哪些SCS或者哪些频带组合。
其中，直接通信业务对应的逻辑信道和SCS的对应关系确定方式可以采用但不限于如下方式之一：
确定方式1:基于V2X业务的QoS参数确定V2X业务和SCS的对应关系。
比如PPPR或者时延参数等，确定V2X业务和SCS的对应关系。
确定方式2:高层配置V2X业务和SCS的对应关系，所述高层指的是非接入层，比如SA2定义的ProSe相关协议层。
直接通信终端通过直接通信业务对应的逻辑信道和SCS对应关系以及SCS和频带资源的对应关系就可以确定在步骤(1)确定的可用频带上哪些频带资源可以作为所述直接通信业务对应的逻辑信道的候选频带资源。
MAC层根据终端对候选频带资源列表内的频带资源的测量结果确定该直接通信业务对应的逻辑信道在直接通信接口传输使用的频带资源。
(3)具体资源选择。
直接通信终端在所选择的频带资源上进一步为终端每个直接通信业务对应的逻辑信道分配资源。
步骤3：直接通信接口数据发送。
根据步骤2中确定的各个直接通信业务对应的逻辑信道使用的资源进行直接通信接口数据的发送。
