Description

一种资源调度方法及相关设备 技术领域
本申请涉及无线网络技术领域，尤其涉及一种资源调度方法及相关设备。
背景技术
基于蜂窝网络的D2D(Device-to-Device，设备对设备)通信，是在系统的控制下允许终端之间通过复用小区资源直接进行通信的技术，它能够增加蜂窝通信系统频谱效率，降低终端发射功率，在一定程度上解决无线通信系统频谱资源匮乏的问题。
为了提升交通系统的安全性和智能化，智能交通的系统理念逐渐兴起。智能交通可以利用新一代的通信网络和数据处理能力，提高交通系统的整体效率，降低能量损耗，增加运输的安全和便捷。V2X(Vehicle to Everything，车联网)技术允许汽车与所有附近其它汽车及道路基础设施进行连续通信，比如，汽车与红绿灯、校区和铁路道口等设施之间通信。通信设备可以是车内嵌入式远程信息处理系统，或者是智能手机等移动设备。V2X技术使得车与车、车与基站、基站与基站之间能够通信，从而获得实时路况、道路信息、行人信息等一系列交通信息，从而提高驾驶安全性、减少拥堵、提高交通效率、提供车载娱乐信息等。
长期演进(Long Term Evolution，LTE)是目前重要的无线通信技术，基于LTE的V2X通信课题在第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)中正在进行标准化工作。在LTE版本14(release 14)V2X协议中，用户设备(User Equipment，UE)在侧向链路(sidelink)上资源分配有两种模式，一种是模式3(mode 3)，该种模式由基站调度发送数据所使用的资源，另一种是模式4(mode 4)，该种模式由用户设备自主选择发送数据所使用的资源。在半静态调度中，基站可以给UE配置至少一个SPS配置，但是，在通过SPS配置进行资源调度时存在资源浪费的问题。

具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
请参见图1，图1是本申请实施例提供的一种资源调度系统的架构示意图，该资源调度系统包括第一设备101、第二设备102和第三设备103，其中，第一设备101可以为用户设备，第二设备102可以为网络设备，第三设备103也可以为用户设备，也可以为中继节点(Relay node)。用户设备可以指终端设备，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。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。网络设备可以是用于与用户设备通信的设备，可以为接入点、中继节点、基站收发台(Base Transceiver Station，BTS)、节点B(NodeB，NB)、演进型节点(Evolutional Node B，eNB)或5G基站(Next generation Node B，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。
应理解，本申请实施例中，终端设备可以是安装在汽车里面的通信终端或车载通信设备，还可以是其它能够实现通信功能的模块化、可拆卸的车载终端。终端设备在功能上能够实现车与车(Vehicle to Vehicle，V2V)、车与人(Vehicle to Pedestrain，V2P)、车与基础设施(Vehicle to Infrastucture，V2I)等业务的信息通讯。
在图1所示的资源调度系统中，第一设备可以与第三设备或其他用户设备进行端到端通信，第一设备与第三设备或第一设备与其他用户设备之间通信的链路可以为侧行链路(sidelink)。第一设备与第二设备之间通信的链路可以为上行链路或下行链路。当第三设备为中继节点时，第一设备与第三设备之间通信的链路可以为上行链路或下行链路。第一设备还可以通过第三设备连接到第二设备。第二设备可以调度第一设备，例如，第二设备可以为第一设备分配第一设备向第二设备或向第三设备或向其他用户设备发送数据的资源。
本申请实施例还适用于其他资源调度系统，该资源调度系统包括第一设备、第二设备。其中，第一设备可以为终端设备，第二设备可以为终端设备或中继节点。第二设备可以调度第一设备，例如，第二设备可以为第一设备分配第一设备向第二设备或向其他终端设备发送数据的资源。第二设备可以与网络连接，第一设备可以通过第二设备连接到网络。
在LTE release 14 V2X协议中，UE在侧向链路上进行资源分配存在两种模式：第一，mode 3，该模式由基站调度UE发送数据的资源；第二，mode 4，该模式由UE自主选择发送数据的资源。mode 3包括动态调度和半静态调度(Semi-persistent scheduling，SPS)。在半静态调度中，基站可以给UE配置至少一个SPS配置，每个SPS配置用一个索引来指示。该两种模式具体流程如下：
在mode 3中，基站可以通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)激活/释放(或去激活)一个SPS配置。包括：PDCCH承载的下行控制信息(Downlink control information，DCI)中包含激活/释放指示信息和SPS配置索引指示信息。UE根据DCI 可以确定一个时域位置和一个频域位置，UE根据该时域位置(子帧)和频域位置、以及SPS配置的周期，确定出一个子帧集合，将该子帧集合上对应频域位置上的资源作为UE用于发送数据的资源。其中，一个子帧上的资源用于传输一个传输块(Transmission block，TB)。当每个TB重传次数不为0时(每个TB可以重传至少一次，而现有标准中每个TB最多重传1次)，UE还可以根据DCI确定出每个TB对应的重传的资源。
在mode 4中，UE可以基于侦听(sensing)进行资源选择或资源重选。UE基于sensing结果选择资源，并预留资源。UE可以向其他UE发送指示信息，该指示信息用于指示该UE预留资源的间隔。其他UE接收到该指示信息后，在选择资源时可以排除该UE预留的资源，从而避免UE发送数据时发生碰撞。其中，该指示信息包含于侧行控制信息(Sidelink control information，SCI)中，具体的，SCI中的资源预留域承载该指示信息。但是，在mode 3中，由于是由基站统一进行调度，UE不用去sensing其他UE将要使用的资源，因而SCI中的资源预留域设置为0，即没有指示资源预留。
使用mode 3的UE，以下简称为mode 3 UE。使用mode 4的UE，以下简称为mode 4 UE。
但是，mode 3 UE使用的资源池可以与mode 4 UE使用的资源池重叠。为了减少mode 4 UE选择的资源可能与mode 3 UE使用的资源发生碰撞，被激活的SPS配置的mode 3中UE发送的SCI中的资源预留域设置为SPS周期，这样mode 4 UE能够通过sensing检测到基站SPS调度的mode 3 UE使用的资源。另外，由于基站无法获知mode 4 UE选择的资源，基站在调度mode 3 UE的资源时，可能会与mode 4 UE选择的资源发生碰撞。因此，mode 3 UE或mode 4UE可以进行sensing，并将sensing结果上报给基站，基站根据sensing结果进行资源调度mode 3 UE。sensing结果可以包括候选资源或者可用资源。或者，sensing结果可以包括不可用的资源。或者，sensing结果包括某些资源上的信号强度/信号功率信息(比如，接收信号强度指示(Received Signal Strength Indication，RSSI)。
本申请实施例中，在时域上的时间单元可以为以下任意一种：传输时间间隔(Transmission Time Interval，TTI)，子帧或时隙等。以下以时间单元为子帧为例。
如图2所示，图2是本申请实施例提供的一种资源调度的示意图。假设UE使用基站配置的SPS资源发送数据，SPS的周期为P(例如P＝100)，并设置资源预留域的值(例如设置为1)，用于指示预留该子帧后的第100个子帧处的资源。UE在子帧/TTI n+200后某一子帧收到SPS release指示后，释放该SPS配置对应的授权(grant)，因此，UE不会使用n+300上的资源。然而UE在收到SPS release指示前的一个该SPS的资源上，即子帧n+200上的资源发送的SCI中，指示了n+300上的资源被预留。其他UE接收到该SCI在资源选择时将n+300的资源排除，导致n+300的资源被浪费。为了解决上述技术问题，提出了如下解决方案。
请参见图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，该方法包括但不限于如下步骤：
S301，第二设备向第一设备发送半静态调度SPS配置，所述SPS配置用于确定周期性资源。
其中，第一设备可以根据SPS配置确定周期性资源，第一设备可以使用该周期性资源发送数据。第一设备可以使用该周期性资源在端到端通信的链路上向其他终端设备发送数据，或者使用该周期性资源向第三设备发送数据，或者使用该周期性资源向第二设备发送数据。所述SPS配置可以包括以下至少一项：SPS的周期或SPS配置索引。所述周期性资源可以为 一组时频资源，该一组时频资源在时域上呈周期性。第一设备可以根据SPS配置中的周期确定所述周期性资源的周期。
S302，第二设备或第三设备向第一设备发送第一信息，所述第一信息用于指示释放所述SPS配置。其中，第一信息可以为DCI，该DCI包括用于指示SPS释放(或去激活)的指示信息。
可选的，在所述第一设备接收第一信息之前，所述第一设备可以接收第二设备或第三设备发送的第二信息，所述第二信息用于指示激活所述SPS配置。其中，第二信息可以为DCI，该DCI包括用于指示SPS激活的指示信息。第一设备在接收到第二信息后，可以根据SPS配置确定周期性资源。
S303，所述第一设备在接收到所述第一信息后的第N个所述周期性资源上发送第一指示信息，所述第一指示信息用于指示无预留资源，其中，N为大于或等于1的整数。
具体实现中，第一设备接收到第二设备发送的SPS配置之后，可以确定用于传输数据的周期性资源。在根据该周期性资源传输数据的过程中，如果接收到SPS release指示信息，第一设备可以在接收到所述SPS release指示信息后的N个周期性资源上继续进行数据传输，并在第N个周期性资源上传输第一指示信息，用于指示没有预留资源。其中，第一指示信息可以包含在SCI中。第一指示信息可以承载在SCI中的资源预留域。例如，资源预留域的值为0时，指示没有预留资源。其他终端设备或第三设备接收到该第一指示信息之后，确定第一设备在第N个周期性资源后没有预留资源，因此可以利用第N个周期性资源后的周期性资源。其中，确定个数N可以包括以下五种可选方式：

例如，如图4所示，第一设备接收到第二设备发送的SPS配置，并在激活该SPS配置之后，根据该SPS配置确定用于传输数据的周期性资源，所述周期性资源所在的子帧集合包括子帧n、子帧n+100、子帧n+200、子帧n+300等。第一设备可以在子帧n、子帧n+100上发送第三指示信息，指示资源预留间隔为100。当第一设备在n+100后某一子帧收到SPS release指示信息时，如果确定N为1，则第一设备在接收到SPS release指示信息之后进行一次传输后，也就是子帧n+200后释放该SPS配置，在子帧n+200上传输的SCI中的资源预留域设置为0，通知其他终端设备子帧n+200后没有预留资源，从而没有资源被浪费。
可选地，在步骤S302之前，第二设备或第三设备向第一设备发送授权，所述授权用于所述第一设备确定周期性资源。
第一设备在接收到所述授权后，根据授权和SPS配置确定周期性资源。具体地，第一设备根据授权确定至少一个资源时域信息和至少一个资源频域信息，并根据SPS配置，确定一组时频资源，该一组时频资源在时域上呈周期性，这一组时频资源为所述周期性资源。

可以理解的是，本申请还包括另一实施例，只包括步骤S301，S302，S304，而不包括步骤S303。可选地，该实施例还可包括上述实施例中的可选步骤。
在本申请实施例中，第一设备首先接收第一设备发送的半静态调度SPS配置，确定周期性资源；然后接收第二设备或第三设备发送的第一信息，第一信息用于指示释放SPS配置；最后在接收到第一信息后的第N个周期性资源上发送第一指示信息，第一指示信息用于指示无预留资源，通过在第N次数据传输之后释放SPS配置，保证了第N个周期性资源后的周期性资源可以被其他设备利用，从而节约了网络资源。
请参见图5，图5是本申请另一实施例提供的一种资源调度方法的流程示意图，该方法包括但不限于如下步骤：

S503，所述第一设备在第N个所述周期性资源上发送第一指示信息，所述第一指示信息用于指示无预留资源。
具体实现中，第一设备可以在N个周期性资源上进行数据传输，并在第N个周期性资源上传输第一指示信息，用于指示没有预留资源。其中，第一指示信息可以包含在SCI中。第一指示信息可以承载在SCI中的资源预留域。例如，资源预留域的值为0时，指示没有预留资源。其他终端设备或第三设备接收到该第一指示信息之后，确定第一设备在第N个周期性资源后没有预留资源，因此可以利用第N个周期性资源后的周期性资源。
可选的，所述第一设备可以在所述第N个所述周期性资源前的所述周期性资源上发送第三指示信息，所述第三指示信息包括或用于指示资源预留间隔，所述资源预留间隔由所述第一设备根据所述SPS配置确定。具体地，所述资源预留间隔可以根据SPS配置中的周期确定。例如，SPS配置中的周期为100，则第三指示信息用于指示资源预留间隔为100。其中，第三指示信息可以包含在SCI中。第三指示信息可以承载在SCI中的资源预留域。例如，资源预留域的值为1时，指示资源预留间隔为100。其他终端设备或第三设备接收到该第三指示信息之后，确定第一设备在发送该第三指示信息的资源之后间隔100个子帧的一个频域资源被第一设备预留。
可选的，第一设备可以在SPS配置被激活后的所述第N个所述周期性资源上发送所述第一指示信息。具体的，第一设备可以在接收到所述SPS配置后确定SPS配置被激活。或者第一设备可以在接收到SPS激活信息后确定SPS配置被激活。
可选的，第一设备可以在接收到所述SPS配置后的所述第N个所述周期性资源上发送所述第一指示信息。
例如，如图6所示，第一设备接收到第二设备发送的SPS配置，并且根据SPS配置所包含或指示的周期性资源的个数N确定N＝4。根据该SPS配置和个数N确定用于传输数据的周期性资源，所述周期性资源所在的子帧集合包括子帧n、子帧n+100、子帧n+200和子帧n+300。第一设备可以在子帧n、子帧n+100、子帧n+200上发送第三指示信息，指示资源预留间隔为100。第一设备在接收到SPS配置之后第4个周期性资源后，也就是子帧n+300后释放所述SPS配置。第一设备可以在子帧n+300上传输的SCI中的资源预留域设置为0，通知其他终端设备子帧n+300后的资源没有被预留，从而没有资源被浪费。在实际应用中，第一设备可以维护一个计数器。当确定个数N后，计数器的值设置为个数N。每到一个周期性资源后，则该计数器减1。当该计数器为0时，UE释放SPS配置，即不再使用该SPS配置确定传输数据的资源。
可选的，第一设备可以在接收到第一信息后的所述第N个所述周期性资源上发送所述第一指示信息。
又如，如图7所示，第一设备接收到第二设备发送的SPS配置和DCI，该DCI激活SPS配置，并根据SPS配置或DCI所包含或指示的周期性资源的个数N确定N＝3。根据该SPS配置、个数N确定用于传输数据的周期性资源，所述周期性资源所在的子帧集合包括子帧n+100、子帧n+200、子帧n+300第一设备可以在子帧n+100、子帧n+200上发送第三指示信息，指示资源预留间隔为100。第一设备在接收到SPS激活指示信息之后第3个周期性资源后，也就是子帧n+300后释放或去激活该SPS，在子帧n+300上传输的SCI中的资源预留域设置为0，通知其他终端设备子帧n+300后的资源没有被预留，从而没有资源被浪费。在实际应用中，第一设备可以维护一个计数器。当确定SPS配置被激活后，计数器的值设置为个数N。每到一个周期性资源后，则该计数器减1。当该计数器为0时，UE释放该SPS配置，即不再使用该SPS配置确定传输数据的资源。
可选的，当所述第一设备在所述第N个所述周期性资源前未接收到第三信息时，所述第一设备在所述第N个所述周期性资源上发送所述第一指示信息，所述第三信息用于指示重激活所述SPS配置。当所述第一设备在所述第N个所述周期性资源前接收到第三信息时，第一设备可以再次确定N个周期性资源。该N个周期性资源为接收到所述第三信息之后的N个周期性资源、或者为前一次N个所述周期性资源之后的N个所述周期性资源。其中，重激活SPS配置也可以为更新SPS配置或重初始化SPS配置。第三信息可以由第二设备发送，也可以由第三设备发送。可以理解的是，当所述第一设备在所述第N个所述周期性资源前未接收到第三信息时，所述第一设备可以立即发送第一指示信息，也可以执行完其他步骤后再发送第一指示信息。当所述第一设备在所述第N个所述周期性资源前接收到第三信息时，第一设备可以立即再次确定N个周期性资源，也可以执行完其他步骤后再确定N个周期性资源。
如图8所示，在SPS配置被激活并确定N＝3后，第一设备可以在子帧n、子帧n+100、子帧n+200上进行三次传输。但是在子帧n+100之后以及子帧n+200之前接收到SPS重激活的指示信息，因此，在SPS配置被激活后第一设备只经过了2次数据传输，也就是只经过了2个周期性资源，第一设备重新确定了N个周期性资源，并在重激活SPS的指示信息之后的子帧n+200、子帧n+300以及子帧n+400上进行3次数据传输，也就是3个周期性资源，如果在子帧n+400之前没有接收到SPS重激活的指示信息，则在子帧n+400上传输的SCI中的资源预留域设置为0，通知其他终端设备子帧n+400后没有预留资源，从而没有资源被浪费。
又如图9所示，在SPS配置被激活并确定N＝3后，第一设备可以在子帧n、子帧n+100、 子帧n+200上进行三次传输。当在子帧n+100之后以及子帧n+200之前接收到SPS重激活的指示信息之后，第一设备又确定了N个周期性资源，因此第一设备在子帧n、子帧n+100、子帧n+200上经过3次数据传输后，也就是经过3个周期性资源后，又确定了3个周期性资源所在的子帧为子帧n+300、子帧n+400以及子帧n+500，如果在子帧n+500之前没有接收到SPS重激活的指示信息，则在子帧n+500上传输的SCI中的资源预留域设置为0，通知其他终端设备子帧n+500后没有预留资源，从而没有资源被浪费。
可选的，所述第一设备在所述第N个所述周期性资源前可以接收到第三信息，第三消息包括或指示周期性资源的个数M，所述第三信息用于指示重激活所述SPS配置。其中，重激活SPS配置也可以为更新SPS配置或重初始化SPS配置。第一设备可以根据第三消息确定周期性资源的个数M，该M个周期性资源为接收到所述第三信息之后的M个周期性资源、或者为N个所述周期性资源之后的M个所述周期性资源。第三信息可以由第二设备发送，也可以由第三设备发送
如图10所示，在SPS配置被激活并确定N＝3后，第一设备可以在子帧n、子帧n+100、子帧n+200上进行三次传输。但是在子帧n+100之后以及子帧n+200之前接收到SPS重激活的指示信息，并指示M＝2。因此，在SPS配置被激活后第一设备只经过了2次数据传输，第一设备重新确定在SPS重激活的指示信息之后的2个周期性资源，所在的子帧为子帧n+200、子帧n+300，如果在子帧n+300之前没有接收到SPS重激活的指示信息，则在子帧n+300上传输的SCI中的资源预留域设置为0，通知其他终端设备子帧n+300后没有预留资源，从而没有资源被浪费。
又如图11所示，在SPS配置被激活并确定N＝3后，第一设备可以在子帧n、子帧n+100、子帧n+200上进行三次传输。当在子帧n+100之后以及子帧n+200之前接收到SPS重激活的指示信息，并指示M＝2。因此第一设备在子帧n、子帧n+100、子帧n+200上经过3次数据传输后，又确定了2个周期性资源，所在的子帧为子帧n+300、子帧n+400，如果在子帧n+400之前没有接收到SPS重激活的指示信息，则在子帧n+400上传输的SCI中的资源预留域设置为0，通知其他终端设备子帧n+400后没有预留资源，从而没有资源被浪费。
可选的，当所述第一设备在所述第N个所述周期性资源前接收到第四信息时，所述第一设备在所述第N个所述周期性资源上发送所述第一指示信息，所述第四信息用于指示释放所述SPS配置。当所述第一设备在所述第N个所述周期性资源前未接收到第四信息时，所述第一设备确定所述第N个所述周期性资源后的周期性资源。其中，第四消息可以为DCI，DCI，该DCI可以包括指示用于SPS释放的指示信息，也可以不包括指示用于SPS释放的指示信息。第四信息可以由第二设备发送，也可以由第三设备发送。可以理解的是，当所述第一设备在所述第N个所述周期性资源前接收到第四信息时，所述第一设备可以立即发送第一指示信息，也可以执行完其他步骤后再发送第一指示信息。当所述第一设备在所述第N个所述周期性资源前未接收到第四信息时，第一设备可以立即确定所述第N个所述周期性资源后的周期性资源，也可以执行完其他步骤后再确定所述第N个所述周期性资源后的周期性资源。
如图12所示，在SPS配置被激活并确定N＝3后，第一设备可以在子帧n、子帧n+100、子帧n+200上进行三次传输。由于在子帧n+200之前没有接收到SPS释放的指示信息，因此第一设备又确定了N个周期性资源，所在的子帧为子帧n+300、子帧n+400以及子帧n+500，由于在子帧n+300之后以及子帧n+400之前接收到SPS释放的指示信息，因此在子帧n+500上传输的SCI中的资源预留域设置为0，通知其他终端设备子帧n+500后没有预留资源，从 而没有资源被浪费。
可选地，在步骤S502之前，第二设备或第三设备向第一设备发送授权，所述授权用于所述第一设备确定周期性资源。
第一设备在接收到所述授权后，根据授权和SPS配置确定周期性资源。具体地，第一设备根据授权确定至少一个资源时域信息和至少一个资源频域信息，并根据SPS配置，确定一组时频资源，该一组时频资源在时域上呈周期性，这一组时频资源为所述周期性资源。
可选地，在步骤S502之后，本实施例还包括步骤S504：所述第一设备在第N个所述周期性资源对应的时刻后释放所述SPS配置，其中，N为大于等于1的整数。释放所述SPS配置可以包括以下至少一项：不再根据该SPS配置确定周期性资源，清除所述周期性资源对应的授权。

可以理解的是，本申请不限定步骤S503和步骤S504的先后顺序。
可以理解的是，本申请还包括另一实施例，只包括步骤S501，S502，S504，而不包括步骤S503。可选地，该实施例还可包括上述实施例中的可选步骤。
