具体实施方式
下面结合本申请实施例中的附图对本申请的实施例进行描述。
本申请的说明书和权利要求书及上述附图中的术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
请参照图1，为本申请实施例提供的一种通信系统的架构示意图，为了便于描述和理解，在图1所示的架构中仅示出了一个接入点和两个站点，并以接入点与站点之间的通信进行举例说明。可以理解的是，在实际场景中，还可以包括多个站点或多个接入点，除了接入点与站点之间的通信之外，也可适用于接入点与接入点之间，站点与站点之间的通信。本申请实施例不作任何限定。
在图1所示架构下，由接入点10，第一站点20和第三站点30组成。
其中，接入点10是指为无线局域网(WLAN)用户终端(包括第一站点20和第二站点30)接入网络的设备。其可以是通信服务器、路由器、交换机、网桥、计算机、手机等。
第一站点20和第二站点30可以是需要与网络通信的用户终端。用户终端又可以称为移动终端、终端设备、用户设备等，其可以是计算机、手机、平板型电脑、手持设备、增强现实(Augmented Reality，简称AR)设备、虚拟现实(Virtual Reality，简称VR设备、机器类型通信终端或是其他可以接入网络的设备。
在本申请实施例中，第一站点20和第二站点30位于接入点的信号覆盖范围内，三者可以位于一个基本服务集(Basic Service Set，简称BSS)内。由于两个站点的位置较近或工作链路的频率相近，当二者同时与接入点进行通信时，将会相互的干扰。因此需要进行合理的调度来避免或减少干扰。
下面结合图2-图5对本申请测量干扰的方法进行详细描述。
请参见图2，图2为本申请实施例提供的一种测量干扰的方法的流程示意图；具体包括如下步骤：
S201.第二站点在第二链路上接收第一站点在第一链路上发送的测量信号。
可选地，所述测量信号可以为所述第一站点在所述第一链路上发送的任意一个数据包；第二站点可以根据预设周期选择在第二链路上接收一个数据包来进行干扰测量，也可以随机的任意选择一个数据包来进行干扰测量，本申请实施例不作任何限定。
或者，所述测量信号可以为所述第一站点接收所述接入点广播的干扰测量通知帧后，在所述第一链路上发送的测量信号。此时，在步骤S201之前，还可以包括步骤S200，接入点广播干扰测量通知帧，通知第一站点在第一链路上发送测量信号，并通知第二站点在 第二链路上侦听所述测量信号。
其中，第二链路为一个广泛的概念，用于与第一链路进行区别，其具体可以是除第一链路外的任意一条链路。在本质上，第二站点用于侦听测量信号的链路可统称为用于测试的接收链路。
可选地，接入点可以指定一个或多个第二站点准备接收测量信号，或者也可以不指定，如果不指定，则第二站点可以自主决定是否进行测量。该干扰测量通知帧可以是一种新定义的帧，或重用协议中已有的帧(比如非数据通知(Null Data Packet Announcement，简称NDPA)帧)。
S202.所述第二站点根据接收到的测量信号生成测量结果。
请参见图3，图3为测量结果包含的字段的一种帧结构示意图，具体可包括如下字段：
第一站点标识和/第一链路标识；第二站点标识和/或第二链路标识；是否存在跨链路干扰和/或跨链路信号衰减大小。
其中，是否存在跨链路干扰，用于定性的指示两个站点之间的两条链路上是否存在干扰。其可以是一个布尔型变量例如用1表示存在干扰，用0表示不存在干扰，具体可以通过接收功率大小和站点设备自身的去干扰能力比较得到。
第一站点标识指定发送测量信号的站点，第一链路标识指定第一站点在哪个链路上发送测量信号(这两项信息可能存在一一对应关系，可以只包含其一)，第二站点标识指定需要接收测量信号的站点，第二链路标识指定第二站点在哪条链路上接收测量信号(这两项信息可能存在一一对应关系，可以只包含其一)。链路标识可以设置为链路地址或其他形式的标识信息如整数等。对于一个仅支持单链路操作的站点，它的链路地址和站点地址相同，它的链路标识也可以和站点标识相同(或者也可以设置为映射关系)，此时，可在链路标识和站点标识中选择一个发送即可；对于一个支持多链路操作的站点，它的所有链路地址可以和站点地址相同，因此，在这种情况下需要利用链路标识来区分不同的链路，此时，可同时发送站点标识和链路标识；另一种可能是支持多链路操作的站点下的链路地址各不相同，此时可发送站点标识，以及链路标识(例如可将链路标识设为链路地址)，即可区分不同的链路。
跨链路信号衰减大小，用于指示从第一站点的第一链路到第二站点的第二链路之间的测量信号衰减大小。
当第二站点接收到测量信号之后，可以获得测量信号的接收功率的大小，从而可以根据接收功率的大小和第二站点自身的去干扰能力比较确定是否存在跨链路干扰。具体地，对于第二站点，判断一个外来信号如本申请中的测量信号是否干扰本设备，需要计算第二站点自身的发送功率大小和干扰信号的接收功率大小的比值(即计算信号干扰噪声比)，并和第二站点自身的抗干扰门限值进行比较，如果大于门限值则判断该干扰并不影响正常收发功能，否则影响。
或者，当第二站点获取到测量信号在第一链路上的发送功率时，还可以结合接收功率来确定跨链路信号衰减大小。如果知道测量信号在第一链路上的发送功率，可以用发送功率除以接收功率，两个功率的比值即衰减大小(假设为L)，无线通信中通常将L进行(10*logL)数值变换成分贝(dB)单位。比如，若比值为100，则衰减大小为20dB。
当然，第二站点除了在第二链路接收测量信号之外，还可以在第一链路接收测量信号。并根据在第一链路上得到的接收功率与第二站点上预存储的链路间损耗数据来确定跨链路信号衰减大小。例如，第二站点预存储了链路间损耗数据(假设第一链路和第二链路的损耗值为20dB，即信号功率跨链路需要除以100)，根据第一链路上的接收功率(假设为1W)，可以除以100得到第二链路上的等效接收功率0.01W。再利用发送功率与等效接收功率的比值计算得到跨链路信号衰减大小。
通过上述字段，接入点便可以获知到两个站点在第一链路和第二链路同时进行通信时是否存在干扰以及干扰的大小。从而可以在调度时，通过合理安排，降低二者的碰撞几率，提升通信系统的整体吞吐量。
可选地，请参见图4，为测量结果包含的字段的另一种帧结构示意图，具体可包括以下字段中的一个或多个：
发送功率大小，用于指示所述第一站点发送所述测量信号的发送功率；
接收功率大小，用于指示所述第二站点接收所述测量信号的接收功率。
当第二站点在多条链路上进行测量信号的接收和测试时，上述的第二链路标识，接收功率大小，以及，接收功率和发送功率的比值这三个信息字段可以包含与多条链路相对应的多组信息，以对应第二站点在多条链路上的测量结果。例如在第二链路1上对应第二链路标识1，接收功率大小1，以及，接收功率和发送功率的比值1，在第二链路2上对应第二链路标识2，接收功率大小2，以及，接收功率和发送功率的比值2。
S203.所述第二站点将所述测量结果发送给接入点。
可选地，在所述第二站点将所述测量结果发送给接入点之前，所述方法还可以包括：
所述第二站点接收所述接入点广播的干扰测量通知帧，所述干扰测量通知帧中携带用于指示所述第二站点反馈测量结果的反馈指示；
或者，所述第二站点接收所述接入点发送的反馈测量结果通知帧，所述反馈测量结果通知帧用于通知所述第二站点反馈测量结果。
为了通知第二站点反馈测量结果，所述接入点可以在所述干扰测量通知帧中携带反馈指示。通过该反馈指示，可以指定第二站点的反馈方式(如反馈链路，反馈时间及反馈类型)，第二站点可以按照指定的方式将测量结果反馈给接入点。如果存在多个第二站点时，可以向每个第二站点发送一个干扰测量通知帧，每个第二站点可以按照各自指定的方式来反馈各自的测量结果。或者也可以向所有第二站点发送相同的干扰测量通知帧，指定不同的第二站点发送测量结果的链路和时间；可选地，第二站点在自由选择的链路上进行信道竞争，将测量结果反馈给接入点，不同第二站点反馈给接入点的测量结果可以是同时发送或者非同时发送。
除了在干扰测量通知帧中进行指示之外，或者，所述接入点也可以向所述第二站点发送反馈测量结果通知帧，通知所述第二站点反馈测量结果。当存在多个第二站点时，可选地，接入点可以向每个第二站点分别发送一个反馈测量结果通知帧来请求测量结果。
可选地，参照图5，为干扰测量通知帧包含的字段的一种帧结构示意图，所述干扰测量通知帧可以包括以下字段：
第一站点标识和/或第一链路标识；发送功率大小，用于指示所述第一站点发送所述测 量信号的发送功率；第二站点标识和/或第二链路标识。
可选地，参照图6，为干扰测量通知帧包含的字段的另一种帧结构示意图，所述干扰测量通知帧还包括以下字段中的一个或多个：
反馈链路标识，用于指示所述第二站点反馈所述测量结果的链路；
反馈时间，用于指示所述第二站点反馈所述测量结果的时间；
接收功率反馈门限，用于指示所述第二站点反馈接收功率的门限值；
反馈类型，用于指示所述第二站点反馈跨链路干扰大小的信息类型。
其中，当存在多个第二站点时，第二站点标识，第二链路标识，反馈链路标识和反馈时间可以包含多组信息，对应多个第二站点的接收方式和反馈方式。其中，第二站点标识指定需要接收测量信号的站点，第二链路标识指定第二站点在哪条链路上接收测量信号(这两项信息可能存在一一对应关系，干扰测量通知帧可能只包含其一)，反馈链路标识指定该第二站点在哪条链路上反馈测量结果，反馈时间指定该第二站点在哪个时间点反馈测量结果；接入点可以用第二站点标识字段的特殊值如0指定所有第二站点都接收测量信号，也可以使用接收链路标识字段的特殊值如0指定对应的第二站点在所有链路上接收测量信号；接收功率反馈门限字段指定了当第二站点接收信号功率大小的最小值，当接收功率小于反馈门限时，第二站点不反馈具体的接收功率大小；反馈类型字段指定第二站点完成测量信号接收后向接入点反馈的指示跨链路干扰大小的信息类型，该反馈类型可以是测量信号接收功率的绝对值或是接收功率相对测量信号发送功率的相对值，又或者是标识是否存在跨链路干扰的布尔值。
当接入点接收到第二站点反馈的测量结果之后，接入点可以根据所述测量结果生成干扰信息，将干扰信息发送给所述第一站点。例如，接入点可以提取测量结果中与第二站点和第一站点之间的跨链路干扰相关的信息，来发送给第一站点，当存在多个第二站点时，接入点可以将每个第二站点和第一站点之间的跨链路干扰相关的信息单独提取并发送给第一站点，也可以对多个第二站点和第一站点之间的跨链路干扰相关的信息进行汇总，再发送给第一站点。
可选地，可以由所述接入点选择时间和链路(确保第一站点可以在选择的时间和链路上能够正常接收到干扰信息)，向所述第一站点发送所述干扰信息；
或者，也可以是所述接入点接收所述第一站点发送的干扰信息请求帧，向所述第一站点发送所述干扰信息。
参照图7，为干扰信息包括的字段的一种帧结构示意图，所述干扰信息可以包括以下字段：
第一链路标识；第二链路标识；第二站点标识；是否存在跨链路干扰和/或跨链路信号衰减大小。
需要说明的是，图3-图7所示的帧结构并不限定各个字段的排列顺序。
此外，所述第二站点的数量大于或等于一个，当所述第二站点的数量大于一个时，所述方法还包括：
所述接入点将所述干扰信息发送给其他的一个或多个第二站点。
当存在多个接入点时，测量干扰的方法类似，此处不再赘述。
需要说明的是，由于接入点或站点的物理位置或工作链路的频率可能发生变化，因此，所述第二站点测量干扰，可以根据预设周期进行。通过周期性的测量干扰并更新信息，可以确保系统长期稳定的运行。
在本申请实施例中，通过对跨链路干扰的测量及结果上报，可以使得接入点能够保存所有关联站点间不同链路上的干扰情况，站点也可以保存与自身存在跨链路干扰的其他站点信息以及相应的干扰水平。当已知这些干扰情况后，接入点可以避免给相互干扰的两个站点同时发送数据包，每个站点在检测到其干扰站点正在向接入点发送数据时，此时也应该避免向接入点发送数据。从而减少不同站点数据发送的碰撞概率，从而提升总体的吞吐量，提高了系统运行的效率。

S801.接入点向第一站点和第二站点广播干扰测量通知帧。
S802.第一站点在第一链路上发送测量信号。
可选地，当不存在步骤S301时，测量信号可以是第一站点在第一链路上发送的任意一个数据包。
S803.第二站点在第二链路上接收所述测量信号，根据接收所述测量信号的接收功率生成测量结果。
例如，可以直接在测量结果反馈接收功率的大小，由接入点根据接收功率的大小和测量信号发送功率的大小确定是否存在跨链路干扰或计算跨链路信号衰减大小，也可以由第二站点根据测量信号的接收功率与发送功率确定是否存在跨链路干扰或计算跨链路信号衰减大小。S804.第二站点向接入点反馈接收所述测量信号得到的测量结果。
S805.接入点根据测量结果生成干扰信息。
