Description

资源的配置方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种资源的配置方法及装置。
背景技术
随着无线多媒体业务的发展，一方面，人们对高数据速率和用户体验的需求也日益增长；另一方面，公共安全、社交网络、近距离数据共享、本地广告等应用场景使得人们对了解附近人或事物并与之通信即邻近服务(Proximity Services，简称为PS)或者称为单边连接(Sidelink)业务的需求也逐渐增加。这样一来，就会对传统蜂窝网络的系统容量和覆盖提出较高的要求。
但是，传统的以基站为中心的蜂窝网络，对高数据速率以及邻近服务的支持方面存在明显的局限性，在这种需求背景下，代表未来通信技术发展新方向的设备到设备(Device-to-Device，简称为D2D)技术应运而生。D2D技术的应用，可以减轻蜂窝网络的负担、减少用户设备的电池功耗、提高数据速率，并改善网络基础设施的鲁棒性，很好地满足上述高数据速率业务和邻近服务的要求。
图1是根据相关技术中的D2D UE进行直接发现/通信的示意图，如图1所示，D2D技术可以工作在授权频段或非授权频段，允许多个支持D2D功能的用户设备即D2D用户设备(D2D User Equipment，简称为D2D UE)在有网络基础设施或无网络基础设施的情况下进行直接发现/直接通信。目前，D2D的应用场景主要有三种：一种是，UE1和UE2在蜂窝网络的覆盖下进行数据交互，用户面数据不经过网络基础设施，如图1所示的模式1；另一种是，如图1所示的模式2，对于弱/无覆盖区域的UE第一终端传输下的UE4，允许信号质量较差的UE4通过附近有网络覆盖的UE3与网络进行通信，这样能帮助运营商扩展覆盖、提高容量；还有一种是，如图1所示的模式3，在发生地震或紧急情况，蜂窝网络不能正常工作的情况下，允许设备间直接通信，UE5，UE6和UE7间控制面和用户面都不经过网络基础设施而进行一跳或多跳的数据通信。
D2D技术通常包括D2D发现技术和D2D通信技术。其中，D2D发现技术是指，用于确定第一用户设备是否邻近第二用户设备的技术，通常，D2D UE间可通过发送或接收发现信号来发现对方；D2D通信技术是指，D2D用户设备之间部分或全部通信数据可以不通过网络基础设施而直接进行通信的技术。需要说明的是，终端使用D2D技术与终端直接通信使用的接口为PC5接口，终端与服务基站进行通信使用的接口称 之为Uu接口。
D2D UE在进行D2D发现或D2D通信之前，首先，都需要分别获取各自相应的无线资源，根据相关3GPP标准会议的进展，无论是D2D发现还是D2D通信中的获取无线资源，都存在两种资源分配方式，即基于UE选择获取资源分配的方式获取资源(本文中简称为第一资源分配方式)或是由基站为UE调度分配专有的资源(本文中简称为第二资源分配方式)进行D2D发现或D2D通信。其中，第一资源分配方式通常由基站或是系统预分配一个D2D资源池，参与D2D发现或D2D通信的UE，或者邻近服务UE(Proximity Service based UE，简称为ProSe UE)监听该资源池，并通过UE选择获取资源分配的方式获取无线资源；而第二资源分配方式由基站根据ProSe UE的请求为ProSe UE分配合适的无线资源。
从公共安全的角度来看，公共安全网络系统需要为第一响应人提供多媒体等服务手段来完成任务，要求具有单点通信和组内通信功能。具体来讲，公共安全场景的D2D通信包含如下类型：单播，组播，广播。单播指D2D用户设备之间一对一的通信模式，而组播与广播是针对D2D用户设备一对多的通信模式。单播通信可看成是组播通信的特殊形式，如D2D通信组内只包含两个用户设备，此时D2D组播通信相当于单播通信。与此同时，公共安全场景的通信要求具有很强的鲁棒性，能够在当前通信资源短缺或者拥塞或者网络基础设施瘫痪的情况下仍然能够最大限度的提供服务。因此公共安全要求D2D通信不仅在有网络覆盖场景下工作，也要求在部分覆盖以及无网络覆盖场景下工作。在无网络覆盖场景下，D2D用户设备可以通过自组织的方式工作，也可以在无覆盖环境下选取一些D2D用户设备作为中央节点(Central Node，简称为CN)，这些中央节点提供类似基站的功能。为了使得D2D通信可以更好的执行，终端在进行D2D通信之前往往需要首先发现其他终端的存在，因此在公共安全场景下对于D2D发现也要求支持在部分覆盖以及无网络覆盖场景下进行工作。在相关技术中，R12中仅仅定义了一种用于广告的发现消息，采用固定大小的资源块来承载不大于232bits的发现消息。由于在R13中定义了新的发现消息，且消息的可能大于232bits，因此相关的机制无法承载R13定义的发现消息。
针对相关技术中在终端需要持续周期的发送R13的发现消息时，相关D2D发现机制无法承载R13的发现消息的问题，目前尚未提出有效的解决方案。

具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
为了实现部分覆盖以及覆盖外场景下用于公共安全的D2D发现的功能，在R13中新增了多种发现消息类型，包括UE-to-network relay发现消息，UE-to-UE relay发现消息，组成员发现消息，临时移动组标识(Temporary Mobile Group Identity，简称为TMGI)发现消息等，这些发现消息的大小并不统一，且部分发现消息所需要包含的信息量大于232bits，但是相关的D2D发现技术中仅仅定义了一种用于广告的发现消息，且采用固定大小的资源块来承载不大于232bits的发现消息。因此，采用相关的D2D发现机制无法承载R13的发现消息。相关技术中还有一种解决方案是采用D2D通信信道来承载R13的发现消息，当终端每次需要发送发现消息的时候，都需要向控制单元申请资源，由控制单元为终端动态的调度资源，如果终端需要持续的周期发送发现消息，那么就需要持续的周期的发送资源申请，控制单元也需要持续的周期的为终端动态的调度资源，如果终端需要发送N个发现消息，那么上述流程也需要独立的执行N次，效率十分低下。针对上述问题，下面将结合本发明实施例及可选实施例进行相应的说明如何解决上述问题。
本实施例提供了一种资源的配置方法，图2是根据本发明实施例的一种资源的配置方法的流程图一，如图2所示，该方法的步骤包括：
步骤S202：终端接收来自控制单元的一个或多个空口传输的资源配置信息，其中，资源配置信息用于指示设备到设备D2D的空口传输资源；
步骤S204：终端依据一个或多个空口传输资源持续发送一个或多个消息数据。
通过本实施例中的步骤S202和步骤S204，控制单元会向终端发送多个资源配置信息，终端获取了资源配置后，则可以按照配置的周期持续的使用配置的资源块来发送每一个或多个消息数据，解决了相关技术中在终端需要持续周期的发送R13的发现消息时，相关D2D发现机制无法承载R13的发现消息的问题，进而到达了提高效率的效果。
对于本实施例中涉及到的资源配置信息，在本实施例的可选实施方式中可以为半持续调度配置信息，其中，该半持续调度资源的配置信息包括：半持续调度资源的空口网络临时标识、半持续调度资源建立指示、半持续调度资源的配置、半持续调度资源的周期以及半持续调度资源的功率等级。
而在本实施例的另一个可选实施方式中该资源配置信息也可以包括：资源类型的指示信息、资源标识的指示信息、资源周期的指示信息、资源大小的指示信息、资源的功率等级指示信息。
而对于本实施例中步骤S204中的终端依据一个或多个空口传输资源持续发送一个或多个消息数据的方式，可以通过如下方式来实现：终端通过D2D发现信道或D2D 通信信道持续发送一个或多个D2D消息，其中，D2D消息包括：D2D通信消息、D2D发现消息。
此外，在本实施例中的另一个可选实施方式中，即在终端接收来自控制单元的一个或多个空口传输的资源配置信息之前，本实施例的方法还可以包括：
步骤S206：终端向控制单元发送指示信息，其中，指示消息用于指示终端需要发送D2D消息。
而对于上述涉及到的指示信息可以是：用于指示对发送D2D消息感兴趣的第一指示信息，或用于指示请求调度发送D2D消息资源的第二指示信息，或用于指示D2D消息类型的第三指示信息。
其中，该第一指示信息或第二指示信息包括：D2D消息类型的指示信息、D2D消息标识的指示信息、D2D消息索引的指示信息、D2D消息周期索引的指示信息、D2D消息大小的指示信息、D2D消息的功率等级指示信息、D2D消息的发现范围等级信息。
对于本实施例中的发现消息包括但不限于：终端到网络的中继UE-to-network relay发现消息、终端到终端中继UE-to-UE relay发现消息、组成员发现消息、临时移动组标识TMGI发现消息、小区ID标识消息、R12类发现消息、R13类发现消息。
由上述可知，本实施例的方法可以通过控制单元向终端配置的空口传输资源持续传输一个或多个数据消息；而在需要释放该用于传输一个或多个数据消息时，也就是在终端依据一个或多个空口传输的资源持续发送一个或多个消息数据之后，本实施例的方法还包括：
步骤S11：终端向控制单元发送对发送D2D消息不感兴趣的第四指示信息；
步骤S12：终端接收控制单元响应于第四指示信息的第一资源释放信息；
步骤S13：终端释放第一资源释放信息指示的资源。
而在本实施例的另一个可选实施的释放资源的方式中，可以采用如下方式，即在终端依据一个或多个空口的传输资源持续发送数据之后，还包括：
步骤S22：终端接收控制单元发送的第二资源释放信息；
步骤S23：终端释放第二资源释放信息指示的资源
其中，第一资源释放信息和第二资源释放信息包括：资源对应的空口网络临时标识、资源类型的指示信息、资源标识的指示信息、资源索引的指示信息。
由上述本实施例的方式可知，采用了通过终端向控制单元发送指示信息，进而控 制单元向终端发送配置信息，该配置信息用于给终端配置一个或多个空口传输资源。而为了更加明确该指示信息的指示作用，在终端向控制单元发送指示信息之前，本实施例的可选实施方式中采用了如下两种方式：
方式一：终端接收控制单元通过广播信令或者无线链路控制RRC专有信令发送的资源信息，其中，资源信息包括以下至少之一：多种发现消息周期信息、多种发现消息资源块大小的指示信息、多种发现消息的索引、多种发现消息的功率等级指示信息、多种发现消息的发现范围等级信息。
基于上述控制单元向终端发送资源信息，本实施例中的终端向控制单元发送指示信息包括：终端向控制单元发送与发现消息资源信息特征对应的发现消息索引指示信息。也就是说，终端可以直接向控制单元发送索引信息，控制单元根据该索引信息就能知道该终端需要发送的发现消息的属性。
方式二：终端预配置多种发现消息的配置信息，其中，配置信息包括：消息的类型指示信息、消息的索引指示信息、消息的大小指示信息、消息的周期指示信息、消息的功率等级指示信息、消息的发现范围等级指示信息。
也就是说，终端预先被配置有发现消息的配置信息，可以直接告知控制单元终端感兴趣的发现消息是哪一类型。
图3是根据本发明实施例的资源的配置方法的流程图二，如图3所示，该方法的步骤包括：
步骤S304：控制单元向终端发送一个或多个空口传输的资源配置信息，其中，资源配置信息用于指示设备到设备D2D的空口传输资源，空口传输资源用于持续发送需要发送的一个或多个消息数据。
对于本实施例涉及到的资源配置信息可以为半持续调度配置信息，其中，半持续调度资源的配置信息包括：半持续调度资源的空口网络临时标识、半持续调度资源建立指示、半持续调度资源的配置、半持续调度资源的周期以及半持续调度资源的功率等级。
此外，该资源配置信息也可以包括：资源类型的指示信息、资源标识的指示信息、资源周期的指示信息、资源大小的指示信息、资源的功率等级指示信息。
而在本实施例中的步骤S304之前，即在控制单元向终端发送一个或多个空口传输的资源配置信息之前，本实施例还可以包括：
步骤S302：控制单元接收终端发送的指示信息，其中，指示消息用于指示终端需要发送D2D消息，D2D消息包括：D2D通信信息、D2D发现消息。
其中，指示信息包括：用于指示对发送D2D消息感兴趣的第一指示信息，或用于指示请求调度发送D2D消息资源的第二指示信息，或用于指示D2D消息类型的第三指示信息。
