Description

一种资源调度方法及相关设备 技术领域
本申请涉及无线通信技术领域，尤其涉及一种资源调度方法及相关设备。
背景技术
设备到设备(Device to Device，D2D)是指用户设备(User Equipment，UE)之间可以直接进行通信、而不需要经过基站等设备的传输或转发的通信技术。D2D可部署在蜂窝网络覆盖范围内和/或网络覆盖范围之外。中继(UE-to-Network Relay)是在D2D通信中引入的特性，具有灵活部署的优点，能够在不增加现有网络设备的情况下扩大网络覆盖范围，在商用通信、公共安全通信(如地震、战争)等领域有着重要应用。
Rel-12到Rel-14的方案主要是定义了调度模式和资源池模式的D2D通信。基站直接为终端分配D2D传输资源或者资源池，或者，终端自身根据基站广播的资源池或者预配置资源池来选择传输资源。如果终端A位于基站覆盖范围内而终端B位于基站覆盖范围外，终端A作为终端B的中继节点，终端B只能利用预配置的资源或者是基站配置的资源池，但是基站无法给终端B直接调度资源，对于第五代移动通信技术(5-Generation，5G)场景下的D2D通信存在很大的局限性。
发明内容
本申请实施例提供一种资源调度方法及相关设备。可以解决现有技术方案中在中继场景下基站无法给远端UE直接调度资源的问题。

具体实施方式
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作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。
请参见图1，图1是本申请实施例提供的一种D2D连接系统的架构示意图，该系统信息传输系统包括基站、第一终端和第二终端，其中，第一终端为中继UE，位于基站覆盖范围内，第二终端为远端UE，位于基站覆盖范围外。第一终端和第二终端可以是指提供到用户的语音和/或数据连接的设备，也可以被连接到诸如膝上型计算机或台式计算机等的计算设备，或者其可以是诸如个人数字助理(Personal Digital Assistant，PDA)等的独立设备。第一终端和第二终端还可以称为系统、用户单元、用户站、移动站、移动台、远程站、接入点、远程终端、接入终端、用户终端、用户代理或用户装置。基站可以为接入点、节点B、 演进型节点(Evolve NodeB，eNB)或5G基站(Next generation base station，gNB)，指在空中接口上通过一个或多个扇区与无线终端进行通信的接入网络中的设备。通过将已接收的空中接口帧转换为IP分组，基站可以作为无线终端和接入网络的其余部分之间的路由器，接入网络可以包括因特网协议网络。基站还可以对空中接口的属性的管理进行协调。
请参见图2，图2是本申请实施例提供的一种资源调度方法的流程示意图。所述资源调度不依赖于所述基站与所述第二终端之间的物理层信道，而是采用间接的通过高层信令的方式来实现资源的调度控制。如图所示，本申请实施例中的方法包括：
S201，基站接收第一终端通过高层信令发送的调度请求，所述调度请求由第二终端发送给第一终端，所述第一终端为所述基站覆盖范围内的终端，所述第二终端为所述基站覆盖范围外的终端。
具体实现中，所述调度请求可以为周期性业务请求，第二终端可以获取当前业务的流量状况，根据当前业务的流量状况，确定数据业务的业务类型，如果数据业务的业务类型为周期性业务，则通过高层信令向第一终端发送周期性业务请求，第一终端接收到周期业务请求之后，将该周期性业务请求转发给基站。如果数据业务的业务类型不是周期性业务，也可以通过高层信令发送的调度请求。但是，如果当前业务并不是绝对的周期性业务，只是接近于周期性业务，特别是能够接受发送端缓存和业务整形的业务，第二终端也可以向基站发送周期性业务请求，从而获取周期性调度资源。其中，如果数据业务本身就是周期性业务，无需第二终端判断业务类型。
其中，高层信令包括但不限于无线资源控制(Radio Resource Control，RRC)消息。在传统的调度机制中，LTE系统的动态调度主要依靠调度请求(Scheduling Request，SR)、缓存状态报告(Buffer Status Report，BSR)或上行调度授权(UL grant)来进行资源调度，而本申请实施例是通过RRC消息承载原有的底层(如，媒体访问控制(Media Access Control，MAC)的控制信元(Control Element，CE)、或者物理层)的调度功能，避免对MAC以及底层协议的过多影响。
S203，所述基站根据所述调度请求，通过所述高层信令向所述第一终端发送调度资源，所述调度资源由所述第一终端转发给第二终端。
具体实现中，所述基站根据所述周期性的业务请求，分配所述半静态调度 资源；通过所述高层信令向所述第一终端发送所述半静态调度资源，从而节省调度资源以及减少动态调度延迟。其中，半静态调度方式是指在LTE的调度传输过程中，基站在初始调度通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)指示UE当前的调度信息，UE识别是半静态调度，则保存当前调度信息，每隔固定的周期在相同的时频资源位置上进行数据业务的发送或接收。
需要说明的是，按照传统资源调度机制，需要第二终端发送的调度请求在第一终端和第二终端之间的PC5接口(终端与终端之间的接口)上可以使用下行(Sidelink，SL)SR或者SL BSR机制，进而第一终端转发SL SR和SL BSR给基站，在基站收到调度请求后，再向第二终端分配资源并通过Uu接口(基站与终端之间的接口)和PC5接口的调度授权grant消息来指示。但是，MAC消息的传输可能会在第一终端转发时被延迟，SR/BSR和grant之间的时序关系未必能够保证。因此，本申请实施例中基站和覆盖范围外的终端之间基于高层信令来进行调度信令的传输，并向覆盖范围外的终端分配半静态调度资源，不仅实现基站直接给远端终端调度资源的目的，而且节省调度资源以及减少动态调度延迟。
需要说明的是，为了满足数据发送的短间隔，这种半静态配置的传输资源之间的间隔可能比传统的半静态调度(Semi-Persistent Scheduling，SPS)要短。并且，基站和远端UE之间的RRC消息对于中继UE可以是透传的，中继UE不需要对RRC消息进行处理，只是对RRC消息进行转发。中继UE向远端UE发送数据的调度采用Uu接口进行，由基站实施。
在本申请实施例中，基站首先接收第一终端通过高层信令发送的调度请求，所述调度请求由第二终端发送给第一终端，所述第一终端为所述基站覆盖范围内的终端，所述第二终端为所述基站覆盖范围外的终端；然后根据所述调度请求，通过所述高层信令向所述第一终端发送调度资源，所述调度资源由所述第一终端转发给第二终端。通过基站和覆盖范围外的终端之间基于高层信令来进行调度信令的传输，实现了在中继场景下基站直接给远端终端调度资源的目的。
请参考图3，图3是本申请实施例提供的一种资源调度方法的流程示意图。如图所示，本申请实施例中的方法包括：
S301，第二终端通过高层信令向第一终端发送调度请求。
具体实现中，所述调度请求为周期性业务请求，第二终端可以获取当前业务的流量状况，根据当前业务的流量状况，确定数据业务的业务类型，如果数据业务的业务类型为周期性业务，则通过高层信令向第一终端发送周期性业务请求，第一终端接收到周期业务请求之后，将该周期性业务请求转发给基站。如果数据业务的业务类型不是周期性业务，也可以通过高层信令发送的调度请求。但是，如果当前业务并不是绝对的周期性业务，只是接近于周期性业务，特别是能够接受发送端缓存和业务整形的业务，第二终端也可以向基站发送周期性业务请求，从而获取周期性调度资源。其中，如果数据业务本身就是周期性业务，无需第二终端判断业务类型。
