Description

一种随机接入方法及站点
本申请要求在2016年11月01日提交中国专利局、申请号为201610942664.9、发明名称为“一种调度随机接入的方法和设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信领域，尤其涉及一种随机接入方法及站点。
背景技术
无线局域网络由站点组成，站点包括接入点(Access Point，AP)和用户站点(Station，STA)。在一些业务场景中，接入点与站点之间不需要一直进行数据传输，因此接入点与站点之间可以建立调度机制，以使得站点可以进入休眠状态。在调度机制中，将安排调度的站点称为调度站点，调度站点可以为AP，将被调度站点所调度的站点称为被调度站点，将除调度站点和被调度站点之外的站点称为非被调度站点，被调度站点和非被调度站点可以为STA。
被调度站点在调度周期内保持唤醒状态，而在调度周期以外可以进入休眠状态，以节约被调度站点的电量，例如，调度机制可以是802.11标准制定的目标唤醒时间(Target Wake Time，TWT)机制，TWT机制中调度周期为TWT服务周期。当被调度站点从休眠状态变为唤醒状态后，被调度站点需要向调度站点发送传输帧，以报告被调度站点已经进入唤醒状态或者指示被调度站点待发送的数据量，以便调度站点更好地调度该被调度站点进行后续的传输。被调度站点可以采用随机接入机制发送传输帧，即具有随机接入能力的站点均可以在调度站点分配的随机接入资源内随机选择资源块进行传输，例如随机接入机制可以是802.11标准的增补标准802.11ax制定的正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)随机接入机制。
由于现有技术中调度站点分配的随机接入资源可以被任何具有随机接入能力的站点识别，具有随机接入能力的站点包括具有随机接入能力的被调度站点和具有随机接入能力的非被调度站点，所以调度站点为具有随机接入能力的被调度站点分配的随机接入资源也可以被具有随机接入能力的非被调度站点识别。因此，在为具有随机接入能力的被调度站点分配的随机接入资源有限的情况下，当具有随机接入能力的非被调度站点较多时，多个站点同时选择同一资源块进行传输而引起传输碰撞的概率较高，这将导致具有随机接入能力的被调度站点在为其分配的随机接入资源上传输成功概率较低。
综上所述，现有的随机接入机制中存在具有随机接入能力的被调度站点在为其分配的随机接入资源上传输成功概率较低的问题。
发明内容
本发明实施例提供了一种随机接入方法及站点，用以解决现有的随机接入机制中存在的具有随机接入能力的被调度站点在调度站点分配的随机接入资源完成上上行传输的成功概率较低的问题。
第一方面，本发明实施例提供的一种随机接入方法，包括：
调度站点生成资源信息和站点信息，所述资源信息用于指示所述调度站点分配的信道资源，所述站点信息用于指示所述信道资源为第一站点的随机接入资源，以使得第二站点识别所述信道资源为分配给除所述第二站点以外的站点使用的资源，所述第一站点是指具有随机接入能力的被所述调度站点调度的所有站点中的全部或者部分站点，所述第二站点是指具有随机接入能力的所有站点中除所述第一站点之外的站点；
所述调度站点发送所述资源信息和所述站点信息，以使所述第一站点使用所述资源信息指示的信道资源进行随机接入。
其中，第一站点是指具有随机接入能力的被调度站点的统称，第一站点可以包括具有随机接入能力的被调度站点中的全部站点或者部分站点；第二站点是指具有随机接入能力的所有站点中除所述第一站点之外的站点的统称。
上述方法中，调度站点通过站点信息指示，资源信息指示的信道资源为第一站点的随机接入资源，以使得第二站点识别所述信道资源为分配给除第二站点以外的站点使用的资源。使得作为被调度站点的第一站点根据该站点信息的指示在资源信息指示的信道资源内进行随机接入，第二站点根据站点信息的指示，确定在资源信息指示的信道资源内不进行随机接入。通过上述方法可以实现，具有随机接入能力的全部或者部分被调度站点可以抢占调度站点分配的随机接入资源，而具有随机接入能力的其他站点不会抢占调度站点分配的随机接入资源，因此可以提高具有随机接入能力的被调度站点抢占随机接入资源的概率。被调度站点抢占到随机接入资源后采用现有技术在调度周期内向调度站点传输上行传输帧，因此可以提高具有随机接入能力的被调度站点通过调度站点分配的随机接入资源完成上行传输的成功概率。
在一种可能的实现中，所述调度站点发送所述资源信息和所述站点信息，包括：
所述调度站点在所述第一站点的调度周期内发送包括所述资源信息和所述站点信息的触发消息，所述触发消息用于触发多用户上行传输。
这样，调度站点可以通过触发消息发送资源信息和站点信息，以实现第一站点和第二站点接收资源信息和站点信息。
在一种可能的实现中，所述资源信息承载于所述触发消息的资源分配记录中的资源块分配字段，所述站点信息承载于所述触发消息的资源分配记录中的站点标识字段；或者，
所述资源信息承载于所述触发消息的资源分配记录中的资源块分配字段，所述站点信息承载于所述触发消息的共用信息字段或用户信息字段。
在一种可能的实现中，所述站点信息包括预设值，该预设值用于指示所述信道资源为所述第一站点的随机接入资源。
这样，可以通过站点信息包括预设值来实现站点信息的指示。
在一种可能的实现中，在所述调度站点生成资源信息和站点信息之前，还包括：
所述调度站点通过以下消息之一发送所述预设值：广播消息、查询响应消息、关联响应消息、重关联响应消息和目标唤醒时间响应消息。
这样，在第一站点和第二站点接收到调度站点发送的资源信息和站点信息之前，可以通过调度站点发送预设值实现第一站点和第二站点确定该预设值所指示的含义，进而保证第一站点和第二站点在接收到调度站点发送的资源信息和站点信息之后，根据资源信息和 站点信息的指示进行随机接入。
第二方面，本发明实施例提供的一种随机接入方法，包括：
站点接收调度站点发送的资源信息和站点信息，所述资源信息用于指示所述调度站点分配的信道资源，所述站点信息用于指示所述信道资源为第一站点的随机接入资源，以使得第二站点识别所述信道资源为分配给除所述第二站点以外的站点使用的资源，所述第一站点是指具有随机接入能力的被所述调度站点调度的所有站点中的全部或者部分站点，所述第二站点是指具有随机接入能力的所有站点中除所述第一站点之外的站点；

其中，第一站点是指具有随机接入能力的被调度站点的统称，第一站点可以包括具有随机接入能力的被调度站点中的全部站点或者部分站点；第二站点是指具有随机接入能力的具有随机接入能力的所有站点中除所述第一站点之外的站点的统称。
上述方法中，第一站点或第二站点接收调度站点发送的资源信息和站点信息，第一站点或第二站点根据站点信息的指示，使得作为被调度站点的第一站点根据该站点信息的指示在资源信息指示的信道资源内进行随机接入，第二站点根据站点信息的指示确定在资源信息指示的信道资源内不进行随机接入。通过上述方法可以实现，具有随机接入能力的全部或者部分被调度站点可以抢占调度站点分配的随机接入资源，而具有随机接入能力的其他站点不会抢占调度站点分配的随机接入资源，因此可以提高具有随机接入能力的被调度站点抢占随机接入资源的概率。被调度站点抢占到随机接入资源后采用现有技术在调度周期内向调度站点传输上行传输帧，因此可以提高具有随机接入能力的被调度站点通过调度站点分配的随机接入资源完成上行传输的成功概率。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
在本发明实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本发明。在本发明实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/ 或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。本文中字符“/”，一般表示前后关联对象是一种“或”的关系。

本发明实施例提供一种随机接入方法及站点，以解决现有技术中具有随机接入能力的被调度站点通过调度站点分配的随机接入资源完成上行传输的成功概率较低的问题。其中，本发明实施例提供的方法及站点是基于同一发明构思的，由于方法及站点解决问题的原理相似，因此方法及站点的实施可以相互参见，重复之处不再赘述。
为了更好地理解本发明实施例提供的技术方案，下面先对本发明实施例适用的网络架构进行描述。如图1A所示为本发明实施例提供的技术方案适用的网络架构示意图，如图1所示为无线局域网络，该网络由站点组成，站点包括接入点AP和用户站点STA1-STA4，STA1-STA4与AP之间可以进行数据传输。由于在一些业务场景下，由于STA1与AP之间、以及和STA2与AP之间不需要一直进行数据传输，因此分别在STA1与AP之间、以及和STA2与AP之间建立调度机制，以节约STA1和STA2的电能。
在调度机制中，将安排调度的站点称为调度站点，将被调度站点所调度的站点称为被调度站点，将除调度站点和被调度站点之外的站点称为非被调度站点。在如图1所示的场景下，将AP称为调度站点，将STA1和STA2称为被调度站点，将STA3和STA4称为非被调度站点。
以STA1与AP之间建立调度机制为例，调度机制是指，当被调度站点STA1向调度站点AP表明STA1支持被调度的能力后，AP通过控制帧、管理帧或数据帧等向STA1发送STA1的调度周期，该调度周期包括调度周期的起始时间与调度周期的持续时间，调度周期可以是一次性调度的，也可以是周期性调度的。根据AP的调度，STA1在调度周期内处于唤醒状态，而在调度周期以外可以进入休眠状态。例如，调度机制可以是802.11标准制定的TWT机制，TWT机制中调度周期为TWT服务周期。如图1B所示为STA1和STA2分别在调度周期内和在调度周期以外的状态示意图。
在调度机制中，当被调度站点从休眠状态变为唤醒状态后，被调度站点需要向调度站点发送上行传输帧，以报告被调度站点已经进入唤醒状态或者指示被调度站点待发送的数据量，以便调度站点更好地调度该被调度站点进行后续的传输。当需发送上行传输的被调度站点较多时，由调度站点对需要发送上行传输的被调度站点进行调度是一种效率较高的方法。但由于调度站点无法事先获知哪些被调度站点需要发送上行传输帧，所以调度站点无法直接调度相应的被调度站点，因此可通过采用随机接入机制解决被调度站点发送上行传输的问题，即具有随机接入能力的站点均可以在调度站点分配的随机接入资源内进行随 机接入，例如随机接入机制可以是802.11标准的增补标准802.11ax制定的OFDMA随机接入机制。
虽然随机接入机制可以解决被调度站点在唤醒后发送上行传输的问题，但由于现有技术中所有具有随机接入能力的站点都可以在调度站点分配的资源内进行随机接入，具有随机接入能力的站点包括具有随机接入能力的被调度站点和具有随机接入能力的非被调度站点。因此，在调度站点分配的随机接入资源有限的情况下，具有随机接入能力的非被调度站点会抢占一定的随机接入资源，这将导致具有随机接入能力的被调度站点通过调度站点分配的随机接入资源完成上行传输的成功概率较低。
实施例一
为了解决上述现有技术中具有随机接入能力的被调度站点通过调度站点分配的随机接入资源完成上行传输的成功概率较低的问题，本发明实施例提供了一种随机接入方法及站点。下面详细介绍本发明实施例提供的技术方案。
如图2所示，本发明实施例提供了一种随机接入系统，该系统200包括调度站点201、第一站点202和第二站点203。其中，调度站点201可以为接入点，第一站点202是指具有随机接入能力的被调度站点201调度的所有站点中的全部或者部分站点，第一站点202为具有随机接入能力的被调度站点，第二站点203是指指具有随机接入能力的所有站点中除第一站点202之外的站点，即第二站点203可以是具有随机接入能力的非被调度站点，也可以是具有随机接入能力的被调度站点，第一站点202和第二站点203可以为STA。
应理解，本实施例中第一站点是指具有随机接入能力的被调度站点的统称，第一站点可以包括具有随机接入能力的被调度站点中的全部站点或者部分站点；第二站点是指具有随机接入能力的所有站点中除第一站点之外的站点的统称。
随机接入系统200中，调度站点201、第一站点202和第二站点203之间的工作原理如下：
调度站点201，用于生成资源信息和站点信息，该资源信息用于指示调度站点201分配的信道资源，该站点信息用于指示该信道资源为第一站点201的随机接入资源，以使得第二站点202识别该信道资源为分配给除第二站点202以外的站点使用的资源。
所述调度站点发送所述资源信息和所述站点信息，以使所述第一站点使用所述资源信息指示的信道资源进行随机接入用于生成资源信息和站点信息；发送资源信息和站点信息。
第一站点202，用于接收调度站点201发送的资源信息和站点信息；根据该站点信息的指示，在该资源信息指示的信道资源内进行随机接入。
第二站点203，用于接收调度站点201发送的资源信息和站点信息；根据该站点信息的指示，确定在该资源信息指示的信道资源内不进行随机接入。
本发明实施例提供的一种随机接入系统中，调度站点通过站点信息指示，资源信息指示的信道资源为第一站点的随机接入资源，以使得第二站点识别所述信道资源为分配给除第二站点以外的站点使用的资源。作为被调度站点的第一站点根据该站点信息的指示在资源信息指示的信道资源内进行随机接入，第二站点根据站点信息的指示，确定在资源信息指示的信道资源内不进行随机接入。通过上述系统可以实现，具有随机接入能力的全部或者部分被调度站点可以抢占调度站点分配的随机接入资源，而具有随机接入能力的其他站 点不会抢占调度站点分配的随机接入资源，因此可以提高具有随机接入能力的被调度站点抢占随机接入资源的概率。被调度站点抢占到随机接入资源后采用现有技术在调度周期内向调度站点传输上行传输帧，因此可以提高具有随机接入能力的被调度站点通过调度站点分配的随机接入资源完成上行传输的成功概率。
基于与本发明实施例提供的一种随机接入系统的同一发明构思，如图3-1所示，本发明实施例还提供了一种随机接入方法，该方法中调度站点、第一站点以及第二站点之间的交互流程如下：
S301、调度站点生成资源信息和站点信息。
其中，资源信息用于指示调度站点分配的信道资源，站点信息用于指示资源信息指示的信道资源为第一站点的随机接入资源，以使得第二站点识别该信道资源为分配给除所述第二站点以外的站点使用的资源，第一站点是指具有随机接入能力的被调度站点调度的所有站点中的全部或者部分站点，第二站点是指具有随机接入能力的所有站点中除所述第一站点之外的站点。资源信息指示的信道资源可以包括一个或多个子载波组成的子载波集，资源信息可以包括子载波的位置和大小信息。
应理解，第一站点是指具有随机接入能力的被调度站点的统称，第一站点可以包括具有随机接入能力的被调度站点中的全部站点或者部分站点；第二站点是指具有随机接入能力的所有站点中除第一站点之外的站点的统称。第一站点是支持目标唤醒时间的随机接入设备，或有待传输数据的随机接入设备，或有待传输数据的支持目标唤醒时间的随机接入设备。
由于本实施例提供的随机接入方法适用于调度站点与第一站点建立调度机制的场景，因此在S301之前，调度站点向第一站点发送调度信息，该调度信息用于指示第一站点在调度周期内保持唤醒状态，以及在调度周期外可以保持休眠状态。在具体实现时，上述调度信息携带有调度周期的信息，例如调度周期的信息可包括调度周期的起始时间和调度周期的持续时间。调度站点可以将调度信息承载于以下消息之一进行发送：控制帧、管理帧和数据帧。其中，管理帧可以为调度协商帧、调度响应帧、信标帧、关联响应帧、重关联响应帧或探测响应帧。
调度站点与第一站点建立的调度机制可以为802.11标准制定的TWT机制，在此场景下，第一站点的调度周期为TWT服务周期，调度协商帧可以是TWT响应帧。
S302、调度站点发送资源信息和站点信息。
本实施例中可以通过如下方法实现S302：
调度站点在第一站点的调度周期内发送包括资源信息和站点信息的触发消息。
调度站点在第一站点的调度周期内发送的触发消息用于触发上行多用户传输。第一站点进入调度周期内由休眠状态变为唤醒状态，第一站点需要向调度站点发送上行传输帧，触发消息用于触发第一站站点进行上行传输，由于第一站点是具有随机接入能力的被调度站点中全部或者部分站点的统称，第一站点可以不只是一个站点，因此，触发消息用于触发第一站点进行上行多用户传输。多用户上行传输可以是基于OFDMA的上行传输，本实施例中的随机接入是指基于OFDMA的随机接入。上行多用户传输还可以是上行多输入多输出(Multiple-Input Multiple-Output，MIMO)传输、上行空分多址接入(Space Division Multiple Access，SDMA)传输等。
调度站点通过触发消息发送资源信息和站点信息可以分为如下两种情况：
情况一：资源信息承载于触发消息的资源分配记录中的资源块分配字段，站点信息承载于触发消息的资源分配记录中的站点标识字段。
其中，资源分配记录用于指示分配的信道资源以及将该信道资源分配给哪些站点。现有技术中，触发消息的资源分配记录通过资源块分配字段承载用于指示分配的信道资源的信息，通过站点标识字段承载用于指示将该信道资源分配给哪些站点的信息。情况一与现有技术中用于承载资源分配记录的字段相同，但区别在于，情况一中站点标识字段承载的站点信息用于指示分配的信道资源为第一站点的随机接入资源，而现有技术中站点标识字段承载的信息用于指示分配的信道资源为所有具有随机接入能力的站点的随机接入资源。
情况二：资源信息承载于触发消息的资源分配记录中的资源块分配字段，站点信息承载于触发消息的共用信息字段或用户信息字段。
其中，资源分配记录用于指示分配的信道资源以及将该信道资源分配给哪些站点。现有技术中，触发消息的资源分配记录通过资源块分配字段承载用于指示分配的信道资源的信息，通过站点标识字段承载用于指示将该信道资源分配给哪些站点的信息。情况二在现有技术的基础上通过共用信息字段或用户信息字段承载本实施例中的站点信息，即情况二应理解为，触发消息的资源分配记录中的资源块分配字段用于承载用于指示分配的信道资源的资源信息，触发消息的资源分配记录中的站点标识字段承载的信息用于指示分配的信道资源为所有具有随机接入能力的站点的随机接入资源，而触发消息的共用信息字段或用户信息字段承载用于指示分配的信道资源为第一站点的随机接入资源的站点信息。在此情况下以触发消息的共用信息字段或用户信息字段承载的站点信息为准，以使第一站点识别分配的信道资源为第一站点的随机接入资源，第二站点识别分配的信道资源为分配给除第二站点以外的站点使用的资源。
本实施例中，站点信息可以包括预设值，该预设值用于指示资源信息指示的信道资源为第一站点的随机接入资源。该预设值可以是固定值，也可以是动态值。通过将预设值设置为不同的值或者不同的取值范围，可以表示调度站点分配的信道资源为具有随机接入能力的不同站点的随机接入资源，可以为一个或者多个站点。
在调度站点生成站点信息之前，调度站点、第一站点和第二站点应协商获知预设值的含义。因此，在调度站点在生成站点信息之前，通过以下消息之一发送的预设值：广播消息、查询响应消息、关联响应消息、重关联响应消息和目标唤醒时间响应消息。需要说明的是，发送预设值的消息包括但不限于上述提供的消息。
预设值可以是由系统分配，此场景下由系统将预设值的含义通知调度站点，再由调度站点将预设值的含义通知给第一站点和第二站点。预设值也可以是由调度站点分配，此场景下由调度站点将预设值的含义通知第一站点和第二站点。因此，调度站点生成包括预设值的站点信息并发送后，第一站点和第二站点可以通过预先协商获知的该预设值的含义，来确定第一站点可以在调度站点发送的资源信息指示的信道资源内进行随机接入。
其中，由于第一站点可以包括具有随机接入能力的被调度站点中的全部站点或者部分站点，因此本实施例中使用调度站点分配的信道资源进行随机接入的站点可以包括具有随机接入能力的被调度站点中的全部站点或者部分站点。可以通过预设值来指示哪些具有随机接入能力的被调度站点允许在调度站点分配的随机接入资源内进行随机接入。
例如，将预设值设置为1时，表示第一站点为具有随机接入能力的被调度站点中的全 部站点，即预设值表示资源信息指示的信道资源为具有随机接入能力的被调度站点中的全部站点的随机接入资源；将预设值设置为0时，表示第一站点为具有随机接入能力的站点(包括被调度站点和非被调度站点)，即预设值表示资源信息指示的信道资源为具有随机接入能力的站点的随机接入资源。又例如，可以将所有具有随机接入能力的被调度站点进行分组，假设站点1-站点6均为具有随机接入能力的被调度站点，将站点1-站点6分为两组，第一组站点包括站点1-站点3，第二组站点包括站点4-站点6；将预设值设置为10时，表示第一站点为第一组站点，即预设值表示资源信息指示的信道资源为第一组站点的随机接入资源；将预设值设置为01时，表示第一站点为第二组站点，即预设值表示资源信息指示的信道资源为第二组站点的随机接入资源；将预设值设置为11时，表示第一站点为具有随机接入能力的全部被调度站点(包括第一组站点和第二组站点)；将预设值设置为00时，表示第一站点为具有随机接入能力的全部站点。
S303、第一站点接收到调度站点发送的资源信息和站点信息之后，根据站点信息的指示，在资源信息指示的信道资源内进行随机接入。
S304、第二站点接收到调度站点发送的资源信息和站点信息之后，根据站点信息的指示，确定在资源信息指示的信道资源内不进行随机接入。
下面举例说明本实施例提供的一种随机接入方法。
举例说明一
本实施例提供的一种随机接入方法如图3-2所示，如图3-2所示的方法可参见如图3-1所示的方法，主要区别在于，如图3-2所示的方法体现了调度站点发送调度信息的步骤，如图3-2所示的方法的全部解释说明可参见如图3-1所示的方法，此处不再赘述。
举例说明二
本实施例提供的一种随机接入方法如图3-3所示，如图3-3所示的方法可参见如图3-3所示的方法，主要区别在于，如图3-3所示的方法体现了调度站点发送调度信息和预设值的步骤，如图3-3所示的方法中资源信息承载于触发消息的资源分配记录中的资源块分配字段，站点信息承载于触发消息的资源分配记录中的站点标识字段。如图3-3所示的方法的全部解释说明可参见如图3-1所示的方法，此处不再赘述。
举例说明三
本实施例提供的一种随机接入方法如图3-4所示，如图3-4所示的方法可参见如图3-4所示的方法，主要区别在于，如图3-4所示的方法体现了调度站点发送调度信息的步骤，如图3-4所示的方法中资源信息承载于触发消息的资源分配记录中的资源块分配字段，站点信息承载于触发消息的共用信息字段或用户信息字段。如图3-4所示的方法的全部解释说明可参见如图3-1所示的方法，此处不再赘述。
本实施例提供的一种随机接入方法中，调度站点通过站点信息指示，资源信息指示的信道资源为第一站点的随机接入资源，以使得第二站点识别所述信道资源为分配给除第二站点以外的站点使用的资源。作为被调度站点的第一站点根据该站点信息的指示在资源信息指示的信道资源内进行随机接入，第二站点根据站点信息的指示，确定在资源信息指示的信道资源内不进行随机接入。通过上述方法可以实现，具有随机接入能力的全部或者部分被调度站点可以抢占调度站点分配的随机接入资源，而具有随机接入能力的其他站点不会抢占调度站点分配的随机接入资源，因此可以提高具有随机接入能力的被调度站点抢占随机接入资源的概率。被调度站点抢占到随机接入资源后采用现有技术在调度周期内向调 度站点传输上行传输帧，因此可以提高具有随机接入能力的被调度站点通过调度站点分配的随机接入资源完成上行传输的成功概率。
实施例二
本发明实施例还提供了另一种随机接入方法，用于解决现有技术中具有随机接入能力的被调度站点通过调度站点分配的随机接入资源完成上行传输的成功概率较低的问题。该方法涉及调度站点、第一站点以及第二站点，其中，调度站点可以为接入点，第一站点是指具有随机接入能力的被调度站点的统称，第一站点可以包括具有随机接入能力的被调度站点中的全部站点或者部分站点，第二站点是指具有随机接入能力的所有站点中除第一站点之外的站点的统称，第一站点和第二站点可以为STA。
如图4所示，本发明实施例还提供的另一种随机接入方法中调度站点、第一站点以及第二站点之间的交互流程如下：
S401、调度站点生成第一竞争窗口的信息和第二竞争窗口的信息。
其中，第一竞争窗口是指在调度站点分配的信道资源内第一站点进行随机接入的竞争窗口，第二竞争窗口是指在调度站点分配的信道资源内第二站点进行随机接入的竞争窗口，竞争窗口的信息可以包括该竞争窗口的最大值和最小值等信息。
第一竞争窗口的信息与第二竞争窗口的信息之间需要满足以下条件：第一竞争窗口的最大值小于第二竞争窗口的最大值，和/或，第一竞争窗口的最小值小于第二竞争窗口的最小值。
在第一站点的调度周期内，第一站点根据第一竞争窗口的信息指示的竞争窗口随机生成退避计数器的第一初始值，第一站点根据第一初始值完成退避后在调度站点分配的信道资源内进行随机接入；在第一站点的调度周期内，第二站点根据第二竞争窗口的信息指示的竞争窗口随机生成退避计数器的第二初始值，第二站点根据第二初始值完成退避后在调度站点分配的信道资源内进行随机接入。在第一竞争窗口的信息与第二竞争窗口的信息之间满足上述条件的情况下，第一初始值在统计意义上小于第一初始值，因此第一站点可以比第二站点更快地完成退避然后进行随机接入，从而第一站点获得更多的上行多用户传输机会，进而提高具有随机接入能力的被调度站点通过调度站点分配的随机接入资源完成上行传输的成功概率。
S402、调度站点发送第一竞争窗口的信息和第二竞争窗口的信息。
S402中调度站点可以将第一竞争窗口的信息和第二竞争窗口的信息承载于以下帧之一进行发送：控制帧、管理帧或数据帧中。其中，管理帧可以为调度协商帧、调度响应帧、信标帧、关联响应帧、重关联响应帧或探测响应帧。
需要说明的是，在S401和S402中调度站点也可以生成并发送第一竞争窗口的信息和第二竞争窗口的信息中的一个信息。在调度站点仅生成并发送第一竞争窗口的信息的情况下，第一竞争窗口的信息需要满足：相比于第二站点，第一站点根据第一竞争窗口的信息随机生成退避计数器的第一初始值能够使得第一站点更快的完成退避。在调度站点仅生成并发送第二竞争窗口的信息的情况下，第二竞争窗口的信息需要满足：相比于第一站点，第二站点根据第二竞争窗口的信息随机生成退避计数器的第二初始值能够使得第二站点更慢的完成退避。
本实施例中，上行多用户传输可以是上行OFDMA传输、上行MIMO传输、上行SDMA传输等。
S403、第一站点接收第一竞争窗口的信息之后，根据该第一竞争窗口的信息在调度站点分配的随机接入资源内进行随机接入。
S404、第二站点接收第一竞争窗口的信息之后，根据该第二竞争窗口的信息在调度站点分配的随机接入资源内进行随机接入。
上述S403和S404发生在第一站点的调度周期内，第一站点进入调度周期时会从休眠状态变为唤醒状态，此时第一站点需要发送上行传输帧，在第一站点的调度周期内第二站点可能也需要发送上行传输帧，因此第一站点和第二站点均需要通过竞争的方式抢占地调度站点分配的随机接入资源以进行随机接入。本实施例中，第一站点与第二站点分别基于调度站点指示的第一竞争窗口的信息和第二竞争窗口的信息竞争抢占调度站点分配的随机接入资源。
需要说明的是，本实施例中调度站点调度第一站点的过程和调度站点分配随机接入资源的过程均为现有技术，此处不再赘述。
本实施例提供的一种随即接入方法中，调度站点生成并发送第一竞争窗口的信息和第一竞争窗口的信息，其中，第一竞争窗口是指在调度站点分配的信道资源内第一站点进行随机接入的竞争窗口，第二竞争窗口是指在调度站点分配的信道资源内第二站点进行随机接入的竞争窗口，竞争窗口的信息可以包括该竞争窗口的最大值和最小值等信息。在第一站点的调度周期内，第一站点根据第一竞争窗口的信息指示的竞争窗口随机生成退避计数器的第一初始值，第一站点根据第一初始值完成退避后在调度站点分配的随机接入资源内进行随机接入；在第一站点的调度周期内，第二站点根据第二竞争窗口的信息指示的竞争窗口随机生成退避计数器的第二初始值，第二站点根据第二初始值完成退避后在调度站点分配的随机接入资源内进行随机接入。在第一竞争窗口的信息与第二竞争窗口的信息之间需要满足上述条件的情况下，第一初始值在统计意义上小于第一初始值，因此第一站点可以比第二站点更快地完成退避然后进行随机接入，从而第一站点获得更多的上行多用户传输机会，进而提高具有随机接入能力的被调度站点通过调度站点分配的随机接入资源完成上行传输的成功概率。
