具体实施方式
以下结合说明书附图及具体实施例对本发明的技术方案做进一步的详细阐述，应当理解，以下所说明的优选实施例仅用于说明和解释本发明，并不用于限定本发明。
方法实施例一：
如图1所示，本实施例提供一种调度控制方法，所述方法包括：
步骤S100：第一类节点通过下行信道向第二类节点发送指示信息；
所述指示信息包括第二类节点的调度请求信令SR资源的配置信息。
本实施例所调度控制方法应用于第一类节点中，所述第一类节点可以为以下的其中之一：基站、微基站、微微基站、毫微微基站、低功率节点及中继站；
所述第二类节点是一个或一组终端。这里的终端可为人到人H2H的第二类节点、机器到机器M2M的第二类节点、车辆到车辆V2V的第二类节点或设备到设备D2D的第二类节点。所述H2H的第二类节点典型的代表可包括手机等。所述M2M的第二类节点通常为能够进行机器之间通信的节点。车辆到车辆的第二类节点包括车载通信节点。所述D2D节点为设备到设备的通信节点。D2D通信是指终端不经过基站可以直接进行通信，每一个D2D通信链路占用的资源与一个蜂窝通信链路占用的相等，可以提高资源利用率和网络容量。而M2M是第五待移动5G通信的一个研究热点，不仅包括终端之间的直接通信，还包括各种机器之间的通信。所述第二类节点具体可为手机等。
在本实施例中所述第一类节点会向第二类节点发送SR资源的配置信息。所述SR为Scheduling Request的缩写，对应为调度请求信令。
在本实施例中所述第一类节点通过SR资源的调度信息的发送，控制所述第一类节点发送SR的频率、时机等状况信息，从而实现调度控制，从而 第二类节点接入所述第一类节点之后，蜂拥的向所述第一类节点申请资源调度，导致的调度拥塞等现象。
所述SR资源依据以下划分依据的至少其中之一划分为一个或多个SR集合：
发送SR的第二类节点的类型；
发送SR的第二类节点的工作模式；
触发发送SR的业务类型；
触发发送SR的业务类型的组合。
所述第二类节点的类型可包括人到人H2H的第二节点；机器到机器M2M的第二节点；车辆到车辆V2V的第二节点；设备到设备D2D的第二节点等。
第二类节点的工作模式可包增强覆盖工作模式、非增强覆盖工作模式及常规模式等。所述覆盖增强模式为能够连接到采用覆盖增强技术的小区的工作模式。非覆盖增强模式为能够连接到没有采用覆盖增强技术的工作模式。所述常规模式可为所述第二类节点中默认配置的工作模式，所述常规模式可为所述增强覆盖工作模式及非增强覆盖工作模式中的一种，但是所述第二类节点自身不区分常规模式是所述增强覆盖工作模式及非增强覆盖工作模式。当然，根据划分的指标不同，所述第二类节点的工作模式还有其他方式的划分。
触发发送SR的业务类型为第二类节点为实现某一个业务发送的所述SR；触发所述第二类节点发送所述SR的业务的业务类型。所述业务类型的组合包括一个或多个业务的组合。
所述第二节点的业务类型分类包括以下至少其中之一：按照数据包传输速率分类；按照数据包的传输时延分类；按照数据包传输误包率分类；按照数据包的包长进行分类；按照数据包的传输周期分类。这里的数据包 为对应于各种业务的数据包，发送业务数据的数据包。
在本实施例中所述将SR资源划分了一个或多个SR集合。这里的多个集合指的是至少两个SR集合。
将SR资源划分成SR集合，方便所述第一类节点的更有效率的管理和控制。
不同的SR集合对应不同的物理随机接入信道PRACH资源。所述PRACH资源可包括PRACH资源包括PRACH的时频资源和随机接入序列。不同的SR集合对应的不同的PRACH资源可包括：不同的SR集合对应的PRACH的时频资源不同和/或不同的SR集合对应的随机接入序列不同。
这样的话，不同类型的第二类节点、不同工作模式的第二类节点、不同业务类型的第二类节点或不同业务类型组合的第二类节点，将利用不同SR集合对应的PRACH资源进行随机接入，避免同一类型的第二类节点申请资源调度过多，导致其他类型的第二类节点根本无法请求调度的现象。
属于同一SR集合中的第二类节点配置的SR资源不同。这样的话，每一个第二类节点的SR资源不同，每一个第二类节点采用分配给其的SR资源发送调度请求信令。
当然，属于同一SR集合中的SR资源能够供所述第二类节点随机选择。即在一个SR集合中配置有一个或多个SR资源，属于同一SR集合中的第二类节点，随机选择其中的SR资源发送调度请求信令。
不同的SR集合对应的调度优先级不同；其中，所述调度优先级为所述第一类节点响应所述第二类节点发送的SR信息的优先级。通常调度优先级越高，则第一类节点将越快的响应所述第二类节点发送的SR信息。所述SR集合与所述调度优先级的映射关系可以由所述第一类节点配置，也可以是通信标准默认配置的；所述SR集合与调度优先级之间的映射关系的形成方式有多种，不局限于上述两种方式。
如图2所示，本实施例所述方法除了包括步骤S100外，所述方法还包括：
步骤S110：根据第二类节点发送SR信息使用的SR资源，确定所述发送的调度请求信令的SR资源所属的SR集合；
步骤S120：根据所述SR集合确定调度优先级；
步骤S130：根据所述调度优先级响应所述SR信息。
在步骤S110中，将根据第二节点发送SR信息的SR资源，确定出对应的SR集合，并根据SR集合确定出对应的调度优先级，根据调度优先级响应所述SR信息，若调度优先级高，则所述第一类节点将更快的响应所述SR信息，若调度优先级低，可能所述第一类节点将可能稍后在响应所述SR信息。
这样的话，所述第一类节点将根据调度优先级，有先后的响应所述SR信息，能够可能的优先需要快速响应的SR信息，同时能够相对较慢响应的SR信息就稍后再响应，显然这样会使得第一类节点更有调理的响应所述SR信息，减少因为响应的无序性导致用户使用满意度差的现象。
不同的调度优先级对应的SR响应时间窗长度不同，优先级越高，所述SR响应时间窗长度越短；所述步骤S130可包括：在所述调度优先级对应的SR响应时间窗内，向发送所述SR信息的第二类节点发送确认信息；所述确认信息用于通知所述第二类节点成功接收所述SR信息。所述确认信息可包括混合自动重传请求应答HARQ-ACK。
所述方法还包括：
步骤S140：向第二类节点发送响应所述SR信息的调度信息。
所述调度信息包括调度参数等各种信息，所述确认信息是所述第一类节点发送第二类节点，告诉第二类节点第一类节点已经接收到所述SR信息，而所述调度信息是响应所述SR信息进行资源调度形成的调度信息。通 常所述调度信息和所述确认信息一样都可作为响应所述SR信息的响应消息，都应该在对应于所述调度优先级的指定时间内发送。
所述确认信息和所述调度信息在不同信令中发送。将确认信息和调度信息在不同的信令中发送，则所述第一类节点在接收到所述SR信息之后，未完成资源调度形成调度信息之前，可首先发送所述确认信息告知第二类节点已经接收到了所述SR信息，避免第二类节点的SR信息的重复发送。
所述步骤S140可包括：在发送所述确认信息之后，发送所述调度信息。
所述步骤S140具体可包括：基于所述调度优先级确定发送所述确认信息和所述调度信息之间的发送时延；在发送所述确认信息之后，在所述发送时延之后发送所述调度信息。
例如，所述确认信息和所述调度信息都需要在所述SR响应时间窗内发送，若先发送所述确认信息，则根据所述SR响应时间窗和所述确认信息的发送时刻，可以确定出在发送所述确认信息多久之后，必须要发送所述确认信息，这个所述确认信息和所述调度信息之间的允许时间间隔即为所述发送时延的最大值。最后所述第一类节点需要在所述发送时延内发送所述调度信息，以及时进行SR信息的响应和资源调度，避免第二类节点的再次请求接入和SR信息的发送导致的接入拥塞的现象。
所述方法还包括：
向所述第二类节点发送包括所述发送时延的时延信息。在本实施例中所述第一类节点直接通过所述延时信息将所述发送延时告知第二类节点，这样第二类节点在接收到所述延时信息之后，就知道了所述发送延时，将在所述发送延时之后接收所述调度信息。
所述向所述第二类节点发送包括所述发送时延的时延信息，包括：
将所述时延信息与所述确认信息进行联合编码，形成联合编码信息；
向所述第二类节点发送所述联合编码信息。
在本实施例中将所述确认信息和延时信息进行联合编码，一来可以减少第一类节点和第二类节点之间交互的信令的开销，同时通过发送联合编码信息，可以一次性发送确认信息和延时信息，减少了第一类节点和第二类节点之间的信息交互量，降低了第二类节点的功耗。
此处的联合编码，例如利用两个2比特来表示确认信息，这2个比特“00”表示没有收到SR信息；“01”表示所述确认信息，且发送时延为1个量化单位；“10”表示所述确认信息，且发送时延为2个量化单位；“11”表示所述确认信息，且发送时延为3个量化单位。
如图3所示，所述步骤S140还可具体包括：
步骤S141：在发送所述确认信息之后，在所述发送延时内发送第一调度信息；所述第一调度信息包括预约调度时刻；
步骤S142：在所述预约调度时刻达到时，发送第二调度信息。
在本实施例中所述调度信息可包括第一调度信息和第二调度信息。当第一类节点当前较为繁忙，无法立即进行资源调度，可是必须在所述SR响应时间窗内响应所述SR信息，完成SR信息的响应，这个时候为了避免第一类节点的负荷的进一步加剧，所述第一类节点将在所述SR响应时间窗内先发送所述第一调度信息。在所述第一调度信息中包括预约调度时刻。这样，当所述第二类节点接收到所述第一调度信息之后，就会知道在预约调度时刻接收来接收第二调度信息。所述第一类节点根据自身的负载等情况确定好所述预约调度时刻之后，将在所述预约调度时刻发送所述第二调度信息。这样，所述第二类节点就能够在预约调度时刻成功的接收到所述第二调度信息，所述第二调度信息中包括资源调度的参数等，这样就完成了对SR信息的响应。
在本实施例中在发送所述确认信息时，可以单独将所述确认信息发送给每一个第二类节点，也可以将发送给多个第二类节点的确认信息承载在 同一消息中发送给第二类节点。例如，使用信息聚合的方式，将多个第二类节点的确认信息聚合在同一消息中发送，这样减少第一类节点信息的发送次数。
本实施例提供了一种调度控制方法，通过包括SR资源的配置信息的发送，实现了第二类节点的调度控制，避免了拥塞现象。
方法实施例二：
如图4所示，本实施例提供一种调度控制方法，所述方法包括：
步骤S210：接收第一类节点发送的指示信息；其中，所述指示信息包括第二类节点的调度请求信令SR资源的配置信息；
步骤S220：根据所述SR资源的配置信息，发送SR信息。
本实施例所述的调度控制方法能够应用于第二类节点中，所述第二类节点可为终端，例如M2M终端、H2H终端、V2V终端、D2D终端等类型的终端。
在本实施例中所述步骤S210中所述第二类节点将会接收所述指示信息。所述指示信息可包括SR资源的配置信息，将在对应的SR资源上发送SR信息，这样的话，至少实现了第二类节点发送SR信息的控制，进而实现了对第二类节点接入到所述第一类节点的调度控制和资源调度请求的控制。
如图5所示，所述步骤S220可包括：
步骤S221：根据所述SR资源的配置信息，确定第二类节点所属的SR集合；
步骤S222：根据所述SR集合确定SR资源；
步骤S223：利用所述SR资源发送SR信息。
在本实施例中所述步骤S220具体包括确定第二类节点所述的SR集合，并确定该SR集合中配置的SR资源，利用该SR集合中的SR资源发送的 SR信息，并非采用而难以的SR资源进行SR信息的发送，显然实现了对第二类节点SR信息的发送控制。
所述步骤S222可包括：
从所述SR集合中配置给所述第二类节点的SR资源。
由于SR集合中的每一个第二类节点都配置了其对应的SR资源，则此时，在确定SR集合后，在对应的SR集合中找到本第二类节点对应的SR资源来发送所述SR信息。
当然，在另一个示例中，所述SR集合中的SR资源可能并没有单独配置给每一个第二类节点，而是配置了一个或多个SR资源可供属于该SR集合中的第二类节点共用，则此时，所述步骤S222可包括：从所述SR集合对应的SR资源中随机选择用于发送所述SR信息的SR资源。
作为本实施例进一步改进，
如图6所示，所述方法还包括：
步骤S230：根据所述SR集合确定响应优先级；
步骤S240：根据所述响应优先级确定SR响应时间窗长度；
步骤S250：在所述SR响应时间长度内，接收所述第一类节点响应所述SR信息的消息；
步骤S260：若在所述SR响应时间长度内，接收到响应所述SR信息的消息则确认所述第一类节点成功接收到所述SR信息。
在本实施例中所述第二类节点还会根据所述SR集合确定响应优先级，通常响应优先级越高，则所述第一类节点响应所述SR信息的时间越快。在本实施例中所述第二类节点根据所述SR响应时间长度，就能预知合适将接收到第一类节点发送的响应所述SR信息的信息，从而保持唤醒状态。在本实施例中所述第二类节点将在所述SR响应时间长度内去接收并检测第一类节点响应所述SR信息的信息，在接收到所述第一类节点响应所述SR信 息的信息之后，将认为自己已经成功向第一类节点发送的SR信息，至少目前不用重新发送所述SR信息，以导致第一类节点的重新接收的现象。
所述步骤S250可包括：
接收响应所述SR信息的确认信息；
在接收到所述确认信息后，所述第二类节点进入休眠状态或闲置状态；
根据所述SR响应时间长度，在调度信息的发送时刻所述第二类节点唤醒接收响应所述SR信息的所述调度信息。
所述响应所述SR信息的信息可包括确认信息和调度信息。在本实施例中为了进一步节省所述第二类节点的功耗，在所述第二类节点接收到所述确认信息之后，将进入低功耗的休眠状态或闲置状态。在所述休眠状态或闲置状态下，则所述第二类节点不用盲检下行信道，从而能够节省功耗。这里的调度信息包括所述第一类节点对第二类节点发送的SR信息响应从而分配的资源的资源信息。
在具体实现时，所述第二类节点还会从所述第一类节点接收延时信息，所述延时信息包括发送延时，该发送延时表示的是所述调度信息在所述确认信息发送时刻之后的多长时间发送。所述第二类节点将根据所述发送延时，在所述发送延时之后接收所述调度信息。此外，所述调度信息和所述延时信息均可承载在通过联合编码形成的联合编码信息中，所述第二类节点可接收所述联合编码信息，解码所述联合编码信息，得到所述确认信息及所述发送延时。
所述第二类节点将根据所述确认信息的接收时刻和所述SR响应时间窗，可确定出所述调度信息的达到时刻，故所述第二类节点将在预计所述调度信息的达到时刻唤醒，以接收所述调度信息。所述调度信息中包括第一类节点响应所述SR信息进行的资源调度的参数等信息。
此外，若当前所述第一类节点特别忙，一方面需要告知第二类节点发 送的SR信息已经接收到，另一方面不想因为资源调度导致所述第一类节点的负荷进一步加重，拥塞现象进一步增加的问题。在本实施例中所述步骤S250可包括：
接收响应所述SR信息的确认信息；
在接收到所述确认信息后，所述第二类节点接收第一调度信息；所述调度信息包括预约调度时刻；
在接收到所述第一调度信息后，所述第二类节点进入休眠状态或闲置状态；
在所述预约调度时刻醒来，接收所述第一节点发送的第二调度信息；其中，所述第二调度信息包括所述第一类节点响应所述SR信息时为第二类节点分配的资源信息。
本实施例所述第二类节点在接收到所述确认信息之后，将接收调度信息，当前可能接收的调度信息可为第一调度信息。所述第一调度信息可包括预约调度时刻。所述第二节点在接收到所述第一调度信息之后，可以进入休眠状态或闲置状态，在低功耗的状态下，等待接收所述第二调度信息，在第二调度信息中具体包括所述第一类节点响应所述SR信息的资源调度结果或参数等信息。所述第二类节点可以根据所述第二调度信息执行后续的业务请求等操作。
第一类节点在发送所述确认信息时，可能是单独发送给每一个所述第二类节点的，则所述第二类节点单个独自接收即可。所述第一类节点也可能将多个第二类节点的确认信息承载在同一消息中发送，则这个所述第二类节点将通过接收所述消息，同时接收到多个确认信息，根据通信协议或事先协商等处理，从该消息中提取出发送给本第二类节点的确认信息。
本实施例中所述调度控制方法，所述第二类节点可以根据所述指示信息，避免无序的一窝蜂的请求第一类节点进行资源调度，导致的拥塞现象， 减少了拥塞显现的发生，提高了信息交互的有序性。
设备实施例一：
本实施例提供一种通信节点，所述通信节点为第一类节点，所述第一类节点包括：
第一发送单元，配置为通过下行信道向第二类节点发送指示信息；
所述指示信息包括第二类节点的调度请求信令SR资源的配置信息。
本实施例所述的第一类节点可为宏基站、微基站、微微基站、毫微微基站、低功率节点及中继站等通信节点。所述豪微微基站又可称为家庭基站。
所述第一发送单元可包括各种发送接口，该发送接口可为无线发送接口，例如宏基站的X2接口。所述豪微微基站的WiFi接口等。可用于向第二类节点发送指示信息。
所述指示信息中包括SR资源的配置信息，所述SR资源的配置信息，可通过对SR资源的配置，控制第二类节点发送的SR信息的发送，从而避免同一时刻很多第二类节点向第一类节点发送SR信息导致的拥塞现象。所述第二类节点可包括终端，例如，如方法实施例一中所述第二节点的类型包括：人到人H2H的第二节点；机器到机器M2M的第二节点；车辆到车辆V2V的第二节点；设备到设备D2D的第二节点等类型。所述第二节点的工作模式为其中之一：覆盖增强模式；非覆盖增强模式；常规模式。
在具体的实现过程中，所述第一类节点还可包括获取单元。所述获取单元的结构可包括处理器或处理电路等，所述处理器可为中央处理器、微处理器、数字信号处理器或可编程阵列等结果。所述处理电路可为专用集成电路。所述处理器可通过执行指定代码实现上述形成所述指示信息的功能。当然所述获取单元也可包括通信接口，所述通信接口可用于从外设接收所述指示信息。
所述SR资源依据以下划分依据的至少其中之一划分为一个或多个SR集合：发送SR的第二类节点的类型；发送SR的第二类节点的工作模式；触发发送SR的业务类型；触发发送SR的业务类型的组合。本实施例中所述第二类节点的类型、第二类节点的工作模式、业务类型或业务类型的组合的详细描述可参见前述方法实施例再次就不重复了，总之这些都是所述第一类节点进行SR资源划分成SR集合的依据。
不同的SR集合对应不同的物理随机接入信道PRACH资源。这样的话，不同类型的第二类节点或不同工作模式的第二类节点、不同业务类型的第二类节点或不同业务类型组合的第二类节点，接入所述第一类节点的PRACH资源也不同，也可以避免所有PRACH资源被同一类型的第二类节点或同一工作模式的第二类节点抢占用于随机接入的现象，从而更好的实现在各种第二类节点之间的随机接入的几率的公正性。
属于同一SR集合中的第二类节点配置的SR资源不同。属于同一个SR集合中的第二类节点的配置的SR资源也不同。例如，第二类节点A和第二类节点B属于同一个SR集合，在本示例中，所述第二类节点A和第二类节点B都各自被第一类配置的SR资源，显然这个时候，所述第二类节点将采用第一类节点配置给其的SR资源进行SR信息的发送。
在另一个示例中，属于同一SR集合中的SR资源能够供所述第二类节点随机选择。在本示例中同一SR集合的SR资源可为属于同一SR集合中的第二类节点的共用的，若SR集合中的第二类节点需要发送SR信息，可随机选择一个该SR集合中的SR资源。
不同的SR集合对应的调度优先级不同；其中，所述调度优先级为所述第一类节点响应所述第二类节点发送的SR信息的优先级。通过调度优先级的设置，可以方便第一类节点优先响应需要及时响应的SR信息。
如图7所示，所述第一类节点除了包括第一发送单元100之外，还包 括：
第一确定单元110，配置为根据第二类节点发送SR信息使用的SR资源，确定所述发送的调度请求信令的SR资源所属的SR集合；
第二确定单元120，配置为根据所述SR集合确定调度优先级；
响应单元130，配置为根据所述调度优先级响应所述SR信息。
本实施例中所述第一确定单元110、第二确定单元120和所述响应单元130都可对应于处理器或处理电路。所述处理电路可包括专用集成电路。所述处理器可包括微处理器、中央处理器、数字信号处理器或可编程阵列等。
所述第一确定单元110、第二确定单元120和响应单元130可分别对应不同的处理器或处理电路，也可以集成对应于相同的处理器或处理电路。当对应于相同的处理器或处理电路时，所述处理器或处理电路可以采用时分复用或并发线程的方式分别处理上述单元的功能。
在本实施例中，不同的调度优先级对应的SR响应时间窗长度不同，优先级越高，所述SR响应时间窗长度越短；所述响应单元130，具体用于在所述调度优先级对应的SR响应时间窗内，向发送所述SR信息的第二类节点发送确认信息；所述确认信息用于通知所述第二类节点成功接收所述SR信息。在本实施例中所述响应单元130还将包括发送接口，通过向所述第二类节点发送确认信息来告知第二类节点已经成功接收所述SR信息。
第一发送单元100，还配置为向第二类节点发送响应所述SR信息的调度信息。
所述调度信息包括所述第一类节点响应所述SR信息进行的资源调度的调度结果或调度参数，这样的话，所述第二类节点接收到所述调度信息之后，就可以根据所述调度信息完成响应的业务。
所述确认信息和所述调度信息在不同信令中发送。确认信息和调度信息在不同的信令发送，这样的话，所述第一发送单元可以分别发送所述确 认信息和所述调度信息，这样能够方便所述第一类节点灵活的控制向所述第二类节点发送的消息，避免响应所述SR信息的延时大的问题。
此外，所述第一发送单元100，配置为在发送所述确认信息之后，发送所述调度信息。这里相当于所述第一发送单元100首先用于发送确认信息，在发送完所述确认信息之后，再发送所述调度信息，这样有利于及时回复第二类节点已经接收到SR信息，同时为第一类节点进行资源调度提供更加充裕的时间。
可选地，所述第一发送单元100，配置为基于所述调度优先级确定发送所述确认信息和所述调度信息之间的发送时延；在发送所述确认信息之后，在所述发送时延之后发送所述调度信息。所述确认信息和所述调度信息分别发送，但是所述调度信息也不能相隔所述确认信息发送之后的时间太长，否则会导致响应延时大的问题，在本实施例中将根据所述调度优先级确定所述发送时延；确定的方法可以参见对应的方法实施例。在本实施例中所述第一发送单元100可包括计算器或具有计算功能的处理器等，可用来计算所述发送时延。
再比如，所述第一发送单元100，还配置为向所述第二类节点发送包括所述发送时延的时延信息。具体的如，所述第一发送单元100，配置为将所述时延信息与所述确认信息进行联合编码，形成联合编码信息；及向所述第二类节点发送所述联合编码信息。首先所述第一发送单元100还将复用于发送延时信息，这样就能简便的告知第二类节点的确认信息和调度信息之间的发送延时。且在本实施例中所述确认信息和所述时延信息共同被联合编码形成了联合编码信息，这样能够减少信令开销，降低节点之间的信息交互次数和数据量。
此外，所述第一发送单元100，配置为在发送所述确认信息之后，在所述发送延时之后发送第一调度信息；所述第一调度信息包括预约调度时刻； 在所述预约调度时刻达到时，发送第二调度信息。本实施例所述的第一发送单元100还将根据自己当前的负载状况，若当前负量大于指定负载量或负载等级高于指定负载等级，则所述第一发送单元100可在发送完所述确认信息之后，先发送第一调度信息，根据所述负载量或负载等级确定预约调度时刻；在预约调度时刻再发送所述第二调度信息，避免所述第一类节点的过分繁忙的现象。
所述第一发送单元110还用于将发送一个所述第二类节点或多个所述第二类节点的确认信息承载同一消息中发送。
所述第一类节点是以下至少其中之一：
宏基站、微基站、微微基站、毫微微基站、低功率节点及中继站；所述豪微微基站可为家庭基站。所述低功耗节点可为常见的LPN，这里的低功耗节点的常规定义可参见现有技术中。所述第二类节点是一个或一组终端。
总之，本实施例提供了一种第一类节点，能够用于实现方法实施例一中所述调度控制方法，通过第一发送单元的设置来发送指示信息，通过指示信息控制第二类节点的调度请求的拥塞现象。
设备实施例二：
如图8所示，本实施例提供一种通信节点，所述通信节点为第二类节点；
所述第二类节点包括：
接收单元210，配置为接收第一类节点发送的指示信息；其中，所述指示信息包括第二类节点的调度请求信令SR资源的配置信息
第二发送单元220，配置为根据所述SR资源的配置信息，发送SR信息。
本实施例所述的接收单元210可包括各种类型的通信接口，如例如， WiFi接收天线、移动接收天线等，能够从第一类节点接收所述指示信息。
所述第二发送单元220可包括各种类型的无线发送接口，能够利用所述SR资源发送SR信息。本实施例所述第二类节点并非利用任意一个SR资源来发送SR信息，而是要根据指示信息中的SR资源的配置信息来发送，显然实现了所述第一类节点对第二类节点SR信息发送的控制，减少了第一类节点因过多的第二类节点随机发送SR信息导致的拥塞现象。
所述第二发送单元220，配置为根据所述SR资源的配置信息，确定第二类节点所属的SR集合；根据所述SR集合确定SR资源；利用所述SR资源发送SR信息。在本实施例中所述SR资源是被配置成SR集合的，所述第二类节点首先根据SR资源的配置信息，确定其所在的SR集合，再次根据所述SR集合确定SR资源，最后在确定的SR资源上进行SR信息的发送。显然所述第二发送单元220还包括信息处理模块，该信息处理模块可包括处理器或处理电路，所述处理器或处理电路，可用于确定用于发送所述SR信息的SR资源。
在一个示例中，所述第二发送单元220，配置为从所述SR集合中配置给所述第二类节点的SR资源。在本示例中SR集合中给第二类节点单独配置了SR资源，所述第二发送单元220的处理模块可以根据所述第二类节点的标识信息查询所述配置信息，确定出所述SR集合中的配置该第二类节点的SR资源。
在另一个示例中，所述第二发送单元220，配置为从所述SR集合对应的SR资源中随机选择用于发送所述SR信息的SR资源。在本示例中所述SR集合中的SR资源是可以由位于该SR集合中的各个第二类节点所共享的，在本实施例中所述第二发送单元220中的处理模块可以随机的选择一个SR资源来发送所述SR信息，例如随机选择一个当前该SR集合中闲置的SR资源来发送所述SR信息。
此外，所述第二类节点还包括：
第三确定单元，配置为根据所述SR集合确定响应优先级；
第四确定单元，配置为根据所述响应优先级确定SR响应时间窗长度；
所述接收单元210，还用于第一在所述SR响应时间长度内，接收所述第一类节点响应所述SR信息的消息；
确认单元，用于若在所述SR响应时间长度内，接收到响应所述SR信息的消息则确认所述第一类节点成功接收到所述SR信息。
本实施例中所述SR集合与响应优先级有映射关系，故在本实施例所述第二类节点中还设置有第三确定单元。所述第三确定单元和所述确认单元的具体结构可为各种类型的处理器或处理电路。所述第四确定单元的具体结构也可以为各种类型的处理器或处理电路。
所述接收单元具体用于在SR响应时间长度内，接收响应所述SR信息的信息。在本实施例中所述第二类节点还可包括计量所述SR响应时间长度的定时器或计时器等结构。
此外，所述接收单元210，配置为接收响应所述SR信息的确认信息；在接收到所述确认信息后，所述第二类节点进入休眠状态或闲置状态；根据所述SR响应时间长度，在调度信息的发送时刻所述第二类节点唤醒接收响应所述SR信息的所述调度信息。在本实施例中所述接收单元210还包括具有信息处理功能的处理模块，所述处理模块可对应于处理器或处理电路。所述处理器或处理电路嫩巩固在接收到所述确认信息之后，控制所述第二类节点进入低功耗的休眠状态或闲置状态，在需要接收所述调度信息时，唤醒所述第二类节点去接收所述调度信息。这样显然节省了第二类节点的功耗，提高了调度的智能性。
当然本实施例中所述的接收单元210还可配置为接收第一类节点发送的延时信息，该延时信息包括第一类节点发送所述确认信息和所述u调度 信息之间的发送延时。所述接收单元210还将根据所述发送延时，在所述发送延时之后接收所述调度信息。当然所述确认信息和所述延时信息可共同联合编码在同一信息中，例如所述联合编码信息。所述接收单元210通过接收所述联合编码信息，接收所述确认信息和所述延时信息。
可选地，所述接收单元210，配置为接收响应所述SR信息的确认信息；在接收到所述确认信息后，所述第二类节点接收第一调度信息；所述调度信息包括预约调度时刻；在接收到所述第一调度信息后，所述第二类节点进入休眠状态或闲置状态；在所述预约调度时刻醒来，接收所述第一节点发送的第二调度信息；其中，所述第二调度信息包括所述第一类节点响应所述SR信息时为第二类节点分配的资源信息。
第一类节点在发送所述确认信息时，可能是单独发送给每一个所述第二类节点的，则所述接收单元210可用于独自接收所述确认信息。所述第一类节点也可能将多个第二类节点的确认信息承载在同一消息中发送，则所述接收单元2140将用于接收该消息，这样通过接收该消息将同时接收到多个确认信息，根据通信协议或事先协商等处理，从该消息中提取出发送给本第二类节点的确认信息。
在本实施例中所述调度信息被分为了第一调度信息和第二调度信息，所述第一调度信息包括的预约调度时刻，所述预约调度时刻可认为是所述第二类节点能够接收到所述第二调度信息的时刻。本示例所述的接收单元210的结构适用于所述第一类节点负载量加大或负载等级加高的时候，避免长时间等待所述第一类节点发送的调度信息导致的功耗大的问题。
以下结合上述任意实施例提供几个具体示例：
示例一：
在无线通信***中存在基站和终端。基站可相当于前述的第一类节点，所述终端相当于前述的第二类节点。
基站发送指示信息给终端。其中，所述指示信息包括以下至少之一：
终端发送SR信息的的调度请求信令资源的配置信息；
进一步的，所述SR信息通过PRACH资源发送。不同终端配置不同的调度请求信令(SR)发送的PRACH资源，且通过PRACH时频资源和/或随机接入序列区分。不同的业务类型或业务类型的组合的终端配置不同的所述PRACH资源；基站根据检测到SR确定终端需要调度的业务类型，并且为优先级高的业务类型先分配用于业务传输的资源。这样的话，就实现了第一类节点资源调度的梳理和控制，避免了第二类节点的在某一个时间点集中发送SR信息导致的资源调度拥塞的现象。
示例二：
终端从基站接收指示信息；
从指示信息获取发送SR信息的SR资源的配置信息；
根据该配置信息确定SR资源并在对应的SR资源上发送所述SR信息。
结合示例一可知，显然所述终端不可能随机选择一个SR资源来发送所述SR信息，必须采用分配给其的SR资源来发送，从而能够很好的避免现有技术中终端随机采用一个SR资源发送SR信息导致的拥塞现象。
本发明实施例还提供了一种计算机存储介质，所述计算机存储介质中存储有计算机可执行指令，所述计算机可执行指令用于上述调度控制方法的至少其中之一，例如图1至图6所示方法中的一个或多个。本实施例所述的计算机存储介质可包括硬盘、光盘或磁盘等各种类型的存储介质，可选为非瞬间存储介质。
