具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开实施例描述的网络架构以及业务场景是为了更加清楚地说明本公开实施例的技术方案，并不构成对本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
图1是根据一示例性实施例示出的一种应用场景的示意图。该应用场景包括：基站110和至少一个终端。
如图1所示，终端的数量通常为多个，该多个终端位于基站110所管理的小区之内。在本公开实施例中，目标终端可以是基站110所管理的小区内的任一个终端。示意性地，如图1所示，目标终端以标号120表示，基站110所管理的小区内除目标终端120之外的其它终端以标号130表示。本公开实施例中，仅以基站110与目标终端120之间的交互流程进行举例说明，基站110与各个 其它终端130之间的交互流程可参照基站110与目标终端120之间的交互流程。
基站110与终端(例如终端120、终端130等)之间通过某种空口技术互相通信，例如可以通过蜂窝技术相互通信。本公开实施例描述的技术方案可以适用于LTE系统，也可以适用于LTE系统后续的演进系统，如LTE-A(LTE-Advanced)系统、第五代(5th Generation，5G)系统等。
本公开实施例中，名词“网络”和“系统”经常交替使用，但本领域技术人员可以理解其含义。本公开实施例所涉及到的终端可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端设备(terminal device)等等。为方便描述，上面提到的设备统称为终端。本公开实施例所涉及到的基站(Base Station，BS)是一种部署在无线接入网中用以为终端提供无线通信功能的装置。所述基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在LTE系统中，称为演进的节点B(evolved NodeB，eNB或eNodeB)。为方便描述，本公开实施例中，上述为终端提供无线通信功能的装置统称为基站或BS。
在一种可能的设计中，每一个sTTI资源为0.5ms。在另一种可能的设计中，每一个sTTI资源为2个OFDM符号。在TTI缩减为sTTI之后，一个子帧可以包括多个sTTI资源。例如，当每一个sTTI资源为2个OFDM符号时，一个子帧可以包括7个sTTI资源。如果沿用上述方案由高层配置所要激活的sTTI资源的数量和位置，则会限制sTTI资源调度的灵活性，且会存在资源浪费的问题。并且，如果需要调整所要激活的sTTI资源的数量和位置，则需要通过高层进行重配置，期间需要由高层与低层之间进行信令交互，这无疑增加了重配置的耗时，这显然是不符合时延缩减的要求的。基于此，本公开实施例提供一种资源调度方法，和基于这个方法的调度器、基站、终端及系统，以解决sTTI资源的分配和调度问题。本公开实施例提供的技术方案，核心思想是由高层配置SPS的周期，由低层的调度器负责分配和激活sTTI资源。
下面将基于上面所述的本公开实施例涉及的共性方面，对本公开实施例进一步详细说明。
图2是根据一示例性实施例示出的一种资源调度方法的流程图。该方法应 用于基站的调度器中。调度器是基站的一个功能实体，其主要用于负责分配和调度时频资源。该方法可以包括如下几个步骤：
在步骤201中，接收RRC层发送的SPS配置信息，SPS配置信息包括SPS的周期。
在本公开实施例中，由高层(也即RRC层)配置SPS的周期。SPS的周期用于指示相邻两个调度子帧之间的时间间隔。调度子帧是指调度器可以从中选择sTTI资源进行分配和激活的子帧。在本公开实施例中，对SPS的周期长度不作限定，SPS的周期长度包括但不限于40ms、20ms、10ms、5ms、2ms或1ms中的任意一种。在本实施例中，假设上述SPS配置信息是基站为其管理的小区内的目标终端配置的。例如，当基站为目标终端配置的SPS的周期为10ms时，则目标终端的相邻两个调度子帧之间的时间间隔即为10ms。在目标终端的调度子帧内，调度器可以从中选择sTTI资源分配给目标终端，并激活所分配的sTTI资源。
在本公开实施例中，高层在配置SPS配置信息时，存在如下两种可能情况。第一，不给定被激活的sTTI资源的数量和位置；第二，给定被激活的sTTI资源的数量的参考值，但不给定被激活的sTTI资源的位置。针对上述第二种可能情况，SPS配置信息还包括被激活的sTTI资源的数量的参考值，该参考值可以由高层根据实际业务情况进行设定。例如，当每一个sTTI资源为2个OFDM符号时，一个子帧可以包括7个sTTI资源，高层根据目标终端的实际业务情况，比如给定被激活的sTTI资源的数量的参考值为3。
在同时支持0.5ms和2个OFDM符号两种不同的sTTI资源的情况下，如果高层给定被激活的sTTI资源的数量的参考值，则该参考值总共有7种可能取值，该参考值可采用3个bit(比特)进行表示。
在步骤202中，根据SPS配置信息和参考信息，确定目标调度子帧中被激活的sTTI资源。
在本公开实施例中，由低层的调度器负责分配和激活sTTI资源。调度器可以位于MAC(Media Access Control，媒体接入控制)层。调度器根据目标终端的SPS配置信息和参考信息，确定目标终端的各个调度子帧中是否需要激活sTTI资源，以及在确定需要激活目标调度子帧中的sTTI资源的情况下，进一步确定目标调度子帧中被激活的sTTI资源。调度器具体确定目标调度子帧中被激活的sTTI资源的数量和位置。其中，参考信息包括但不限于以下至少 一项：sTTI配置信息、调度器所要调度的数据、无线资源情况。sTTI配置信息包括用于指示每一个sTTI资源的时长的信息，例如sTTI配置信息包括0.5ms和2个OFDM符号两种可选参数。调度器所要调度的数据可以包括调度器所要调度的总数据量、调度器所要为目标终端调度的数据量等信息。无线资源情况可以包括无线资源的分配、占用、质量等情况，例如为其它终端分配sTTI资源的情况、sTTI资源的干扰情况等。调度器根据设定的调度算法，对上述各项信息进行处理，确定目标终端的各个调度子帧中是否需要激活sTTI资源，以及在确定需要激活目标调度子帧中的sTTI资源的情况下，进一步确定目标调度子帧中被激活的sTTI资源。
在一个示例中，如图3所示，假设每一个sTTI资源为2个OFDM符号，则一个子帧包括7个sTTI资源。如图3所示，在目标终端的某一调度子帧内，调度器选择后三个sTTI资源进行激活。进一步地，在目标终端的不同调度子帧内，调度器可根据上述SPS配置信息和参考信息，适当调整被激活的sTTI资源的数量和/或位置。在调度子帧中的sTTI资源被调度器激活之后，该调度子帧即为激活子帧。
在步骤203中，根据目标调度子帧中被激活的sTTI资源向物理层提供激活参数，以使得物理层生成包含有上述激活参数的激活通知，该激活通知用于通知终端在目标调度子帧中被激活的sTTI资源。
激活参数用于指示在目标调度子帧中被激活的sTTI资源。可选地，激活参数用于指示在目标调度子帧中被激活的sTTI资源的数量和位置。例如，当目标调度子帧为目标终端的某一调度子帧时，基站向目标终端发送包含有激活参数的激活通知，该激活通知用于通知目标终端在目标调度子帧中被激活的sTTI资源。
可选地，激活通知为DCI，DCI中包含用于指示被激活的sTTI资源的数量和位置的参数。例如，sTTI资源的数量和位置可以比特映射(bitmap)的方式进行表示。另外，如果高层在SPS配置信息中给定了被激活的sTTI资源的数量的参考值，且选用该参考值作为最终确定的被激活的sTTI资源的数量，则激活通知中包含的激活参数可仅指示被激活的sTTI资源的位置即可，从而节省激活参数所需的比特数。可选地，激活通知以一个子帧为通知周期。当激活通知为DCI时，选用慢速DCI，也即通知周期为一个子帧(也即1ms)的DCI。
此外，对于不同的激活子帧，调度器可以自行根据SPS配置信息和参考信息，适当调整被激活的sTTI资源的数量和/或位置，实现sTTI资源的重配置。当调度器需要去激活sTTI资源时，调度器可向物理层发送去激活指示，以使得物理层生成去激活通知，基站向终端发送去激活通知，通知终端去激活sTTI资源。
综上所述，本公开实施例提供的方法，通过调度器接收RRC层发送的SPS配置信息，根据SPS配置信息和参考信息，确定目标调度子帧中被激活的sTTI资源；解决了相关技术中由高层配置所要激活的sTTI资源，所存在的限制sTTI资源调度的灵活性、资源浪费和增加重配置的耗时的问题；使得sTTI资源的调度不受限于SPS配置的固定限制，提高了sTTI资源调度的灵活性，基站的调度器能够方便地调整sTTI资源的颗粒度，避免资源浪费的问题，且有利于节省重配置的耗时。
另外，本公开实施例提供的方案，适用于上行SPS和下行SPS。
图4是根据另一示例性实施例示出的一种资源调度方法的流程图。该方法应用于终端中。该方法可以包括如下几个步骤：
在步骤401中，接收基站发送的SPS配置信息，SPS配置信息包括SPS的周期。
在本公开实施例中，SPS的周期由基站的高层(也即RRC层)配置。SPS的周期用于指示相邻两个调度子帧之间的时间间隔。通常情况下，SPS配置信息还包括偏移值。终端根据SPS的周期和偏移值，确定基站为终端分配的各个调度子帧的位置。
在步骤402中，根据SPS的周期获取基站发送的激活通知，激活通知中包含激活参数，激活参数用于指示在目标调度子帧中被激活的sTTI资源。
终端确定各个调度子帧的位置之后，在调度子帧内获取基站发送的信息，并对该信息进行解析以确定在该调度子帧内基站是否为本端分配sTTI资源。如果终端在目标调度子帧内获取到基站发送的激活通知，其解析确定该激活通知是基站发给本端的，则终端读取该激活通知中包含的激活参数。激活参数用于指示在目标调度子帧中被激活的sTTI资源。可选地，激活参数用于指示在目标调度子帧中被激活的sTTI资源的数量和位置。
可选地，激活通知为DCI，DCI中包含用于指示被激活的sTTI资源的数 量和位置的参数。例如，sTTI资源的数量和位置可以比特映射(bitmap)的方式进行表示。另外，如果基站的高层在SPS配置信息中给定了被激活的sTTI资源的数量的参考值，且选用该参考值作为最终确定的被激活的sTTI资源的数量，则激活通知中包含的激活参数可仅指示被激活的sTTI资源的位置即可，从而节省激活参数所需的比特数。
在步骤403中，在目标调度子帧内占用被激活的sTTI资源传输数据。
终端在确定目标调度子帧中被激活的sTTI资源之后，便可在目标调度子帧内占用被激活的sTTI资源接收和/或发送数据。
在本实施例中，提供了与基站侧相对应的终端侧的操作流程，终端根据获取到的激活通知确定基站为其分配的sTTI资源，并占用上述被激活的sTTI资源传输数据。本公开实施例提供的方法，sTTI资源的调度不受限于SPS配置的固定限制，提高了sTTI资源调度的灵活性，基站的调度器能够方便地调整sTTI资源的颗粒度，避免资源浪费的问题，且有利于节省重配置的耗时。
图5是根据另一示例性实施例示出的一种资源调度方法的流程图。该方法可应用于图1所示的应用场景中。该方法可以包括如下几个步骤：
在步骤501中，基站的RRC层向调度器发送SPS配置信息，并将SPS配置信息发送给目标终端。
SPS配置信息包括SPS的周期。可选地，SPS配置信息还包括被激活的sTTI资源的数量的参考值。可选地，SPS配置信息还包括建立或释放连接的指示信息，HARQ(Hybrid Automatic Repeat reQuest，混合自动重传)信息等。
在步骤502中，目标终端在接收到SPS配置信息之后，向基站发送第一接收响应。
第一接收响应用于指示目标终端成功接收上述SPS配置信息。
在步骤503中，基站的调度器根据SPS配置信息和参考信息，确定目标终端的目标调度子帧中被激活的sTTI资源。
调度器确定目标终端的各个调度子帧中是否需要激活sTTI资源，以及在确定需要激活目标调度子帧中的sTTI资源的情况下，进一步确定目标调度子帧中被激活的sTTI资源的数量和位置。可选地，参考信息包括但不限于以下至少一项：sTTI配置信息、调度器所要调度的数据、无线资源情况。
在步骤504中，基站的调度器向物理层提供激活参数。
激活参数用于指示目标终端的目标调度子帧中被激活的sTTI资源。可选地，激活参数用于指示在目标调度子帧中被激活的sTTI资源的数量和位置。
在步骤505中，基站的物理层生成包含有上述激活参数的激活通知，并将激活通知发送给目标终端。
激活通知用于通知目标终端在目标调度子帧中被激活的sTTI资源，例如被激活的sTTI资源的数量和位置。可选地，激活通知为DCI。可选地，激活通知以一个子帧(也即1ms)为通知周期。
相应地，目标终端根据SPS配置信息获取基站发送的激活通知。
在步骤506中，目标终端向基站发送第二接收响应。
第二接收响应用于指示目标终端成功接收上述激活通知。
在步骤507中，目标终端在目标调度子帧内占用被激活的sTTI资源传输数据。
在步骤508中，基站的调度器向物理层发送去激活指示。
在步骤509中，基站的物理层生成去激活通知，并将去激活通知发送给目标终端。
当调度器需要去激活sTTI资源时，调度器可向物理层发送去激活指示，以使得物理层生成去激活通知。基站向目标终端发送去激活通知，通知目标终端去激活sTTI资源。
在步骤510中，目标终端在接收到去激活通知之后，向基站发送第三接收响应。
第三接收响应用于指示目标终端成功接收上述去激活通知。之后，目标终端停止占用sTTI资源。
综上所述，本公开实施例提供的方法，通过调度器接收RRC层发送的SPS配置信息，根据SPS配置信息和参考信息，确定目标调度子帧中被激活的sTTI资源；解决了相关技术中由高层配置所要激活的sTTI资源，所存在的限制sTTI资源调度的灵活性、资源浪费和增加重配置的耗时的问题；使得sTTI资源的调度不受限于SPS配置的固定限制，提高了sTTI资源调度的灵活性，基站的调度器能够方便地调整sTTI资源的颗粒度，避免资源浪费的问题，且有利于节省重配置的耗时。
