Description

信道管理方法、接入点和站点
本申请要求于2018年10月29日提交中国专利局、申请号为201811271282.3、发明名称为“信道管理方法、接入点和站点”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
本申请涉及通信领域，特别涉及一种信道管理方法、接入点和站点。
背景技术
无线局域网(wireless local area network，WLAN)的基本服务集合(basic service set，BSS)由多个WLAN设备组成。请参阅图1，其中，一个WLAN设备为接入点(access point，AP)，其余为站点(station，STA)。AP为WLAN网络BSS的管理设备，具有管理功能，例如发送信标(Beacon)广播帧等。STA与AP关联，并通过AP传输业务，以实现与其他设备的通信。
随着无线局域网通用标准802.11协议的发展，WLAN设备支持的传输带宽由传统802.11a协议的20MHz拓展到802.11ax协议的20MHz、40MHz、80MHz、160MHz。802.11协议在大带宽传输的演进过程中，对不同的20MHz进行了划分。请参阅图2，以802.11ax协议中AP的160MHz信道为例，该160MHz信道由2个连续的80MHz构成。160MHz信道包括8个20MHz信道，其中1个20MHz为AP的主20MHz信道，主20MHz信道与另一个相邻的20MHz信道(即AP的辅20MHz信道)构成主40MHz，主40MHz信道与主40MHz相邻的另一个连续的40MHz信道(即辅40MHz信道)构成主80MHz信道，剩下的连续80MHz信道为辅80MHz信道。仅支持20MHz带宽的STA，仅在主20MHz信道上与AP进行数据传输，支持40MHz带宽的STA，可以与AP在主20MHz信道或主40MHz信道上与AP数据传输，支持80MHz带宽的STA，可以与AP在主20MHz信道、主40MHz信道或主80MHz信道上与AP数据传输,支持160MHz带宽的STA，可以与AP在主20MHz信道、主40MHz信道、主80MHz信道或主160MHz信道上与AP数据传输。AP必须在主20MHz信道上发送Beacon等管理帧，以保持后向兼容。AP与STA进行数据传输之前，需要对信道进行侦听，当AP的主20MHz信道空闲时进行传输。
现有技术中，AP的传输带宽能力往往高于STA，请参阅图3-a,例如，AP关联了3个STA，该AP支持160MHz信道，STA-a和STA-b的带宽能力分别80MHz，STA-c的带宽能力为160MHz。由于STA需要在主信道进行数据传输，且STA-a和STA-b只支持80MHz信道，即使160MHz信道都是空闲的，AP也只能在AP的主80MHz信道上通过时分与STA-a和STA-b分别进行数据传输。当STA-a和STA-b工作时，只有主80MHz的信道被使用，因此信道利用率较低。

具体实施方式
本申请实施例提供了一种信道管理方法，用于提升信道的利用率。
本申请实施提供的信道管理方法应用于多种通信连接场景下，包括WLAN、授权辅助接入(License Assisted Access，LAA)系统，非授权频谱(Multefire)通信系统等。以下实施例中以在WLAN系统中的信道管理方法为例进行说明。
请参阅图3-b，为本申请实施例中AP与STA关联的一个实施例示意图。
通过本申请提供的信道管理方法，STA与AP建立通信连接后，可以根据AP发送的信道配置信令切换至AP的辅信道进行数据传输，可以提升信道的利用率。
示例性的，请参阅图3-b，160MHz信道的AP与三个STA关联，分别是带宽能力为80MHz的STA-a、带宽能力为80MHz的STA-b和带宽能力为160MHz的STA-c。若STA-b与AP建立通信连接后，由AP向STA-b发送信道配置信令，指示STA-b切换至辅80MHz信道上进行数据传输，则当AP侦听到160MHz信道空闲时，可以在主80MHz信道传输STA-a的数据，同时可以在辅80MHz信道上传输STA-b的数据；此外，当160MHz信道空闲时，AP还可以同时在主80MHz信道和辅80MHz信道上传输STA-c的数据。本申请实施例提供的信道管理方法，可以有效利用AP辅信道资源，提升信道利用率。
在图1提供的无线局域网中基本服务集合示意图的基础上，请参阅图4，为本申请实施例中信道管理方法的一个实施例示意图。
401、接入点AP与站点STA建立通信连接；
由于STA需要通过AP与其他设备通信，首先，AP与STA需建立通信连接，AP与STA可以通过网络扫描建立通信连接。STA可以通过主动扫描与AP建立连接，也可以通过侦听AP发送的信标帧与AP建立连接。STA在通信连接中还可以通过信令消息获取AP的主辅信道配置信息。STA在AP的主信道上传输入网信令，完成入网。
402、AP向该STA发送第一信道配置信令；
AP向该STA发送第一信道配置信令，指示该STA在第一信道工作即在第一信道进行数据传输，该第一信道为AP的辅信道。第一信道配置信令中可以携带AP为该STA配置的第一信道的信息，如第一信道的中心频点和带宽。此外，第一信道配置信令中还可以包含启动时刻，启动时刻用于指示该STA开始在配置的第一信道进行数据传输的时刻。
本申请实施例提供的信道管理方法，由于AP可以在主信道完成与STA的连接入网过程，然后通过向STA发送第一信道配置信令，指示STA切换至AP的辅信道工作，由于STA可以切换至AP的辅信道工作，AP在同一时刻可以在主信道和辅信道分别与不同的STA进行数据传输，因此可以提高信道的利用率。

601、AP与STA建立通信连接；
首先，AP与STA可以通过网络扫描建立通信连接，网络扫描有多种方式：
可选地，在主动扫描模式下，STA向AP发送探测请求(probe request)帧，当AP侦听到该探测请求后，将向该STA发送探测响应(probe response)帧；
可选地，在被动扫描模式下，STA侦听到AP周期发送的信标(beacon)帧。
STA可以通过AP发送的probe response或beacon消息，确定AP的主信道与辅信道的配置信息，STA在AP的主信道上传输入网信令，包括认证和关联等过程，完成入网。
602、STA向AP发送信道配置信息；
STA向AP发送信道配置信息。
可选地，该信道配置信息用于指示该STA支持在该AP的辅信道进行数据。例如信道配置信息中包含该STA是否支持工作信道配置的字段。例如，1代表该STA支持工作信道配置，0则代表该STA不支持工作信道配置。STA可以将信道配置信息和STA的带宽能力信息一同发送给该AP，也可以单独向AP发送该STA的信道配置信息。此处，对于STA向AP发送信道配置信息的具体方式不做限定。
可选地，对于未向AP发送信道配置信息的STA，AP默认为该STA不支持工作信道配置。
可选地，信道配置信息用于指示该STA支持的信道，该STA支持的该信道中包含该第一信道。例如，STA向AP发送该STA支持的信道，其中包含第一信道，第一信道为辅信道。
需要说明的是，工作信道调整涉及状态机等软件配置和滤波器参数等硬件参数的调整，STA是否支持在AP的辅信道工作由该STA的软硬件处理能力决定，本申请实施例中，仅针对支持在AP辅信道工作的STA，因此，STA将向AP发送信道配置信息，该信道配置信指示该STA支持在该AP的辅信道进行数据传输，或，该信道配置信息用于指示该STA支持的信道，该STA支持的该信道中包含该第一信道。
603、AP为STA配置第一信道，并向STA发送第一信道配置信令；
AP接收步骤602中STA发送的信道配置信息后，该AP可以为STA配置第一信道，AP为STA配置的第一信道由以下因素中的一个或多个决定：该AP每个带宽上的STA数量、负载、占空比、数据发送量或STA的带宽能力。在实际应用中AP为STA配置的信道可以是主信道或辅信道，本申请实施例中以配置的第一信道为辅信道进行说明。

606、AP向STA发送调度信息；
由于STA在辅信道工作，为避免与工作在主信道或其他辅信道STA的数据传输冲突，STA的上行数据传输需由AP调度进行。AP将通过第一信道向STA发送调度信息，以指示STA进行上行数据传输。可选地，调度信息中携带信道信息和时隙信息，该信道信息用于指示STA发送上行数据的信道，可以为第一信道，可以为主信道，也可以为除第一信道以外的其他AP的辅信道，此处不做限定；该时隙信息用于指示该STA发送上行数据的时长。

608、AP为STA配置第二工作信道，并向STA发送第二工作信道配置信令；
AP可以为STA再次配置工作信道，AP为STA配置的第二工作信道由以下因素中的一个或 多个决定：该AP每个带宽上的STA数量、负载、占空比、数据发送量或STA的带宽能力。其中，“第二”仅用于指代特定工作信道，与“第一”之间没有任何的顺序或大小关系。
第二工作信道可以是AP的主信道或AP的辅信道，此处不做限定。可选地，若STA当前工作的信道为主信道，则AP配置的第二工作信道可以是任一辅信道；若STA当前工作的信道为辅信道，则AP配置的第二工作信道可以是主信道，或者是另一辅信道。例如，若步骤604中STA将工作信道切换至AP的第一辅信道，则AP配置的第二工作信道可以为AP的主信道或AP的第二辅信道。
AP为STA配置第二工作信道后，将向STA发送第二工作信道配置信令，该信令用于指示该STA在该第二工作信道进行数据传输。第二工作信道配置信令中包含配置的第二工作信道。此外，第二工作信道配置信令中还可以包含启动时刻，即指示该STA开始在配置的第二信道进行传输的时刻。

可选地，该请求消息中未携带目标信道信息，则该STA可以请求AP为该STA配置工作信道。例如，若STA根据AP的配置在第一信道工作，可以向AP发送请求消息，请求切换至另一信道进行数据传输。
611、AP向STA发送第三信道配置信令；
AP接收STA发送的请求消息即信道切换请求后，AP可以向STA发送第三信道配置信令。
可选地，若STA发送的请求消息中携带目标信道信息，则该AP可以回复该请求消息的响应消息，该响应消息中携带调整指示，当该调整指示为不允许调整时，该STA的信道切换请求被拒绝，信道配置不改变；当该调整指示为允许调整时，该响应消息还可以包括新配置的信道信息；
可选地，若STA发送的请求消息中未携带目标信道信息，AP可以根据该请求消息为该STA配置新的工作信道即第三信道，然后该AP可以向STA发送第三信道配置信令，该第三信道配置信令中携带第三信道信息，携带第三信道信息的方式可以是携带该第三信道的带宽和中心频点，发送第三信道信息的具体形式此处不做限定。若AP拒绝该STA的信道切换请求，则向该STA返回拒绝消息。
本申请实施例中以AP允许该STA切换至第三信道为例进行说明。
612、STA切换工作信道；
STA向AP发送请求消息后，若接收到AP发送的第三信道配置信令，则STA可以切换工作信道。例如，由辅信道切换至主信道，或，由辅信道切换至其他辅信道，或，由主信道切换至辅信道，此处不做限定。本申请实施例中以该STA由辅信道切换至主信道为例进行说明。
若该STA切换至主信道，则可以根据先听后说(listen before talk，LBT)频谱礼仪，对信道进行侦听后，再发送数据。
需要说明的是，步骤610至步骤612为可选步骤，可以执行，也可以不执行，此处不做限定。
本申请实施例提供的信道管理方法，STA在主信道完成接入之后，若AP确认STA支持在AP的辅信道进行数据传输，则AP可以通过信道配置信令将STA配置到辅信道工作。此外，STA可以进行信道切换或再次通过AP发送的信道配置信令进行信道切换。STA在辅信道可以接收下行数据，还可以在AP调度信息的触发下进行上行数据的发送。因此，本申请实施例的方案可以增加AP的辅信道的信道利用率。
