实施例九
在商场等场所中，基于WLAN的无线网络中，AP可以根据STA所在位置，对站点进行定位，判断人流量等，通过802.11az协议实现，AP借助信道探测帧测量不同站点到达站点的序列信息时间信息，由于时间测量的准确性要求，不能允许非本BSS站点对定位序列的空间复用。
存在多个BSS网络如图3所示，BSS1包含AP1、STA A和STA B，BSS2包含了AP2、STA1和STA2。
在BSS1中，AP1发送具有定位请求的定位请求触发帧(Positioning Request Trigger Frame)，通过触发帧中的类型(Type)域表明该帧为定位测量需求帧，调度STA A和STA B站点发送上行MU NDP，AP1接收到上行的MU NDP后，继续发送下行的NDPA以及下行的NDP，帧交换序列如图5所示：
AP1在发送的DL触发帧中使用HE PPDU帧格式发送，AP在物理层信令中的HE-SIG-A中设置为禁止空间复用信令(SR-DISALLOW)，并且在MAC层的触发帧中设置对应调度信息指令，包括接收到的目标(Target)信号强度指示值(RSSI，Received Signal Strength Indicator，)、发送功率空间流等信息，并且设置触发帧中common信息的空间复用指令设置为禁止空间复用信令SR-DISALLOW。
STA A和STA B接收到上述请求定位的Trigger帧后，SIFS间隔反馈HE MU NDP帧，所述的NDP帧在频域间隔分开，使得AP1能够遍历不同站点所发的频域NDP信号。所述STA A和STAB发送的NDP不包含数据单元，帧格式如图4所示，并且在所发送的HE MU NDP帧中的HE-SIG-A 中复制AP1中Trigger帧中的Common Info域中的信息包括设置的禁止空间复用指令即SR-DISALLOW。
AP1接收到STA A和STA B发送的上行HE MU NDP、测量信道、时间等信息用于定位，接着AP1发送下行的NDPA，设置物理层信令中HE-SIG-A域中空间复用字段为禁止空间复用信令SR-DISALLOW，确保该帧不被其他OBSS站点复用，并在SIFS时间后发送下行NDP信道测量帧，并且设置NDP帧中物理层信令HE-SIG-A中空间复用字段为禁止空间复用指令SR-Prohibted。
在BSS2中任意站点如图3所示，STA1或者STA2接收到无线帧，通过类型匹配是WiFi无线帧，解析物理层中HE-SIG-A信令中的BSS color字段判断该帧来自OBSS站点，并解析HE-SIG-A中的SR空间复用域得到该域为禁止空间复用信令(SR-DISALLOW)，站点STA1或STA2保持物理载波检测信道状态为忙，直到本无线帧结束。
实施例十
在WLAN网络中，一个重要的数据传输就是站点需要确认接收到发送给自己的数据，目前网络中下行数据量是远远大于上行数据的，对于下行数据确认的保护也变的很重要。
在802.11ax中支持多块确认(MU-BA，Multiple Block Ack)，即多个站点可以同时以正交频分多址(OFDMA，Orthogonal Frequency Division Multiplexing Access)的方式发送上块确认ACK。如图6所示，BSS1网络中的AP1通过HE MU方式发送下行多用户数据，可以通过OFDMA，多用户-多输入多输出(MU-MIMO)或者两者的结合，STA A和STA B反馈上行的块确认(BA，Block Ack)确认信息。
AP1以OFDMA的方式通过HE MU PPDU帧格式发送下行数据，接着发送携带触发帧，调度站点发送上行确认信息，在以下的情况中的任意一 种：
当AP所调度的帧满足指定的帧类型时：
BA帧/ACK帧，信道测量反馈(Sounding feedback)帧；
AP所调度的帧长度满足预设的长度阈值时；
预设的长度阈值为30字节；
在本实施例中，AP在触发帧中的Common Info域中的信息的空间复用子域设置为禁止空间复用SR-DISALLOW即禁止所有的空间复用行为。
STA A和STA B接收到Trigger帧后SIFS时间间隔后，回复HE Trigger-based PPDU帧格式发送的BA确认信息，不同STA在各自的RU上发送上行确认信息，在发送的HE Trigger-based PPDU中的物理层信令HE-SIG-A的空间复用字段依据接收到的Trigger帧中的common信息中空间复用的信令指示设置为禁止/限制空间复用信令(SR-DISALLOW)。
在BSS2中的站点中，STA1接收到一个无线帧，该无线帧满足接收门限，通过信号特征匹配判断该帧为WiFi无线帧，进步通过L-SIG和RL-SIG类型判断该帧为HE PPDU，解析HE-SIG-A信令的中的PPDU format字段判断该帧是Trigger-based PPDU，并解得BSS color值判断出该帧来自OBSS网络，并解析空间复用字段解得该字段为禁止/限制空间复用信令SR-DISALLOW，站点STA1保持物理载波检测信道状态为忙，直到本无线帧结束。
实施例十一
在精确时间测量(FTM，Fine Time Measurement)帧交互过程中，时间的测量为ms级别，该帧帧交互需要保护，不能让OBSS站点对本次帧交互进行复用，FTM一般用于测量本站点和其他站点距离，本站点可以基于帧交互利用其他站点的位置来决定本站点的位置。FTM的帧序列由发起方发起FTM请求，响应端发送FTM测量帧，发起方和响应方通过记录PPDU 的接收时间来确定位置信息，帧交互序列如图7所示：
在图3中，BSS1中，发起方STA A请求AP进行FTM测量，测量STA A与AP1的距离信息。其中发起方为STA A，响应方为AP1。
发起方通过请求(FTM request)帧发起请求，响应方回复Ack。
响应方在时间测量帧时期(Burst Duration)时间段内的t1_1时刻发送第一FTM测量帧，请求方在t2_1时刻接收到该帧，并在t3_1时刻发送Ack确认信息，并记录该时刻，响应方在t4_1时刻接收到Ack确认信息，并记录该时刻信息。
响应方在t1_2时刻发送FTM帧并携带发送第一FTM测量帧的时刻t1_1和接收Ack的时刻t4_1。
请求方在t2_2时刻接收到含有时间信息FTM_2后通过时间信息t1_1，t2_1，t3_1，t4_1来估计请求方到响应方的距离吗，并记录t2_2时刻。在t3_2发送Ack确认信息。
响应方在t4_2时刻接收到Ack确认信息，并记录该时刻。
在一个时间测量帧时期内，可以有多个测量确认交互，下一个测量交互携带上一个测量确认的时间信息。
在上述请求和响应站点发送的帧序列交互中，站点发送的FTM请求帧，FTM测量帧以及响应的Ack帧中，通过HE PPDU帧格式发送，在物理层的HE-SIG-A信令域的空间复用字段设置为禁止空间复用SR-DISALLOW。
在BSS2中站点STA1或者STA2接收一个无线帧，该帧能量超过接收门限，并通过前导匹配该帧为WiFi帧，进一步通过L-SIG重复判断该帧为HE PPDU，通过解析HE-SIG-A信令域，解析BSS color字段，判断该帧来OBSS，并解析空间复用字段，解得该字段为禁止空间复用SR-DISALLOW，则BSS2中接收到该帧的站点STA1或者STA2，会保持物理载波监听为忙，直到本无线帧的结束。
实施例十二
在WLAN网络中，特别是基于802.11ax协议的数据传输中，站点可以通过触发帧调度多个站点发送上行数据，在某些简单场景，例如AP调度站点发送上行确认信息，站点可以选择不将完整的触发帧发送给站点进行上行数据调度，只需要将Trigger部分信息放在上行多用户响应调度(UMRS，Uplink Multi-user Response Scheduling)控制域，这个域集成在高吞吐(HT，High Throughput)控制域中的A-Control域中，但是在UMRS控制域的信令没有空间复用域，因此对于响应具有UMRS域的帧类型，调度特定帧类型例如BA或者ACK等，须禁止空间复用，可以设置默认的禁止空间复用指令即SR-DISALLOW，SR-DISALLOW表示禁止所有的SR空间复用。
在BSS1中AP1通过OFDMA方式发送下行的HE MU PPDU，调度STA A和STA B发送上行ACK确认信息，并在每个多用户数据中的第一个MAC层数据单元(MPDU，MAC Protocol Data Unit)中含有UMRS Control域，站点接收到该PPDU后，会设置默认的空间复用指令即禁止空间复用信令，帧交互序列如图8所示。
当BSS2中的站点STA1接收到一个无线帧，经过前导匹配，确认该帧为Wi-Fi无线帧，进一步通过L-SIG重复判断出该帧为HE PPDU，进一步通过解得HE-SIG-A，判断格式(Format)域确定帧为基于触发帧的HE PPDU以及BSS Color域该帧来OBSS站点，解析空间复用(Spatial Reuse)域，确认为禁止空间复用信息，STA1则设置其物理载波监听为忙，直到该PPDU帧接收结束。
实施例十三
在WLAN网络中，特别是在基于802.11ax协议的数据通信中，AP可以调度多个站点发送上行数据，从而提高网络的平均吞吐。
在如图3中的情况下，BSS1网络中的AP1发送触发帧调度多个站点 STA A和STA B发送上行数据，该数据是除了信道测量反馈数据和确认信息的其他数据，AP1在Trigger帧中的Common Info域中的空间复用域设置为禁止SRP空间复用和Non SRG OBSS_PD空间复用指令即SRP_AND_NON-SRG-OBSS-PD_DISALLOW，帧传输序列如图9所示。
STAA和STAB接收到触发帧后，会复制触发帧中的空间复用域中的信令即SRP_AND_NON-SRG-OBSS-PD_DISALLOW，设置上行数据帧HE Trigger based PPDU中的物理层信令HE-SIG-A中的空间复用域也为SRP_AND_NON-SRG-OBSS-PD_DISALLOW。
在BSS2中的站点STA1接收到一个无线帧，经过前导匹配，确认该帧为Wi-Fi无线帧，进一步通过L-SIG重复判断出该帧为HE PPDU，进一步通过解得HE-SIG-A，判断Format域确定帧为基于HE触发帧PPDU以及BSS Color域该帧来OBSS站点，解析空间复用(Spatial Reuse)域，确认为SRP_AND_NON-SRG-OBSS-PD_DISALLOW信令，那么STA禁止SRP空间复用和Non SRG OBSS_PD空间复用，但依然可以执行SRG空间复用。
实施例十四
在WLAN网络中，特别是在基于下一代IEEE802.11协议的WLAN网络中，AP可以调度多个用户发送上行数据。
在图3中，BSS1网络中的AP1调度STA A和STA B发送多个下行多用户数据单元，并最后一个数据单元中携带触发帧，调度STA A和STA B发送上行块确认(BA，Block ACK)，如图10所示。
在BSS2网络中STA1，接收到无线帧，通过前导匹配得到该帧为WiFi帧，以及该帧是HE帧，并通过物理层中的BSS color判断出该帧来自OBSS网络，根据物理层中长度信息(即Length的长度)t满足预设的阈值T即t<T。STA 1会保持物理载波监听为忙，直到该PPDU结束。
