具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本申请进行详细说明。应当理解,此处所描述的具体实施例仅用以解释本申请,并不用于限定本申请。
在本申请的描述中,需要理解的是,涉及到方位描述,例如上、下、前、后、左、右等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本申请和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本申请实施例的限制。
应了解,在本申请实施例的描述中,若干的含义为一个以上,多个(或多项)的含义是两个以上,大于、小于、超过等理解为不包括本数,以上、以下、以内等理解为包括本数。如果有描述到“第一”、“第二”等只是用于区分技术特征为目的,而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量或者隐含指明所指示的技术特征的先后关系。
本申请实施例的描述中,除非另有明确的限定,设置、安装、连接等词语应做广义理解,所属技术领域技术人员可以结合技术方案的具体内容合理确定上述词语在本申请实施例中的具体含义。
无线感知,或者WiFi感知,是一种利用WLAN信号对于处于覆盖范围内的用户动作进行识别的一种技术,其主要的工作原理在于,接入点设备在每次接收到信号时,都会对于无线信道进行估计,以提升无线性能。无线信道的估计结果被称为信道状态信息(Channel State Information,CSI),无线信道特征受到收发天线之间物体的位置和特性的影响,因此用户不同的动作和位置会产生不同的无线信道特征,也就是不同的CSI。因此,WLAN设备可以对于CSI进行分析,来获取用户的动作,位置或者其他信息。
相关技术中,通常采用单一的频率触发设备进行感知信号的触发和收集,这种无线感知方式,存在对空口资源的占用的弊端,申请人发现,触发设备会向接入点设备发送报文,而在触发设备持续向接入点设备发送报文的过程中,会存在占用系统空口资源的问题,从而降低了无线感知的能力和效率。
基于此,本申请实施例提供了一种无线感知方法、电子设备及存储介质,无线感知方法是一种提升无线感知的算法,无线感知方法可以应用在接入点设备或触发设备中,使得触发设备可以根据配置信息调整发送感知报文的工作状态,触发设备在调整发送感知报文的工作状态后,可以减少对空口资源的占用,触发设备可以根据覆盖范围内是否有目标物存在来发送感知报文,由于所有的触发设备的并非一直在发送报文,其占用的空口资源较低,从而实现多个触发设备的合理规划和调度,进而有效提高无线感知的能力和效率。此外,通过设置高频触发设备和低频触发设备,实现对多频触发设备进行合理的规划和调度,相比只采用单一频段触发设备实现了更大范围的覆盖,随着带宽提升,感知算法的性能也会提升,本申请实施例中在发现目标物处于近端时,动态的提升了带宽,在尽可能降低空口资源的占用的情况下,可以帮助提升感知算法的性能。不仅如此,在同等功率下,覆盖范围随着频率的降低而升高,所以较低频率触发设备的覆盖范围高于较高频率触发设备的覆盖范围,本申请实施例方法可以提升感知算法的覆盖。
本申请实施例中的接入点设备和触发设备之间可以实现通信连接,接入点设备为一种WLAN设备,也是一种无线接入点(即无线AP或WAP),相当于是连接有线网和无线网的桥梁,它可通过将流量从无线网桥接到有线网中,为现有的有线网增加无线功能,触发设备为任意一个可以发送报文的设备,例如,触发设备可以是用户设备,一个接入点设备可以同时为一个或者多个用户设备进行服务,这些用户设备的形式包括并不限于手机、物联网终端、或者另一个接入点设备等,接入点设备和触发设备之间的通信基于但不限于802.11系列协议。
如图1所示,一个接入点设备可以与多个触发设备通信连接,各个触发设备分别向接入点设备发送报文,接入点设备在接收到报文后,可以对报文进行信道估计,得到各个触发设备的信道状态信息,本申请实施例对上述用于信道估计的报文描述为感知报文,触发设备可以每隔一段时间向接入点设备发送一个感知报文。
如图2所示,触发设备可以包括低频触发设备和高频触发设备,一个接入点设备提供网络接入,同时有不少于2个的触发设备与接入点设备连接。低频触发设备和高频触发设备工作的频段不同,其中,工作频率较低的低频触发设备的天线相对于接入点设备天线的直线距离,大于或等于工作频率较高的高频触发设备的天线相对于接入点设备天线的距离,低频触发设备和高频触发设备可以每隔一段时间向接入点设备发送感知报文,低频触发设备和高频触发设备也可以是一个可以同时工作在两个频段的802.11设备,此时的低频、高频以触发设备实际工作时的频率进行界定。可以理解的是,低频触发设备和高频触发设备均可以有多个, 在此不做具体限制。
需要说明的是,本申请实施例中的低频触发设备和高频触发设备在频率上是相对的,低频触发设备的工作频率低于高频触发设备,例如,在一实施例中,低频触发设备为2.4G触发设备,高频触发设备为5G触发设备,高频触发设备还可以是更高频率的设备,如6G触发设备,在满足本申请实施例要求的前提下,低频触发设备和高频触发设备还可以是其他频率的设备,在此仅以2.4G和5G为例子进行说明。
下面进行详细说明。
本申请实施例提供了一种无线感知方法,应用于接入点设备中,适用于任何满足WiFi5标准的WLAN接入点设备,接入点设备在此不再赘述,参照图3所示,本申请实施例中的无线感知方法包括但不限于步骤S101至步骤S104。
步骤S101,分别接收多个触发设备发送过来的感知报文。
步骤S102,根据感知报文,得到对应的触发设备的信道状态信息。
步骤S103,根据信道状态信息判断对应的触发设备覆盖范围内是否有目标物存在,得到信道判断结果。
步骤S104,根据信道判断结果向触发设备发送配置信息,以使触发设备调整发送感知报文的工作状态。
在一实施例中,接入点设备通过与多个触发设备通信连接,触发设备可以向接入点设备发送感知报文,接入点设备在接收到感知报文后,根据感知报文分别得到对应的各个触发设备的信道状态信息,通过信道状态信息可以对对应的触发设备信号覆盖范围内的用户行为做出判断,本申请实施例可以根据信道状态信息判断对应的触发设备覆盖范围内是否有目标物存在,得到信道判断结果。在一些实施例中,信道判断结果有两种,包括对应的触发设备覆盖范围内有目标物存在的结果,或者对应的触发设备覆盖范围内没有目标物存在的结果,根据这两种结果,接入点设备可以得到配置信息,并向触发设备发送配置信息,触发设备在接收到配置信息后可以对自身进行控制,并调整触发设备本身发送感知报文的工作状态。
可以理解的是,触发设备调整发送感知报文的工作状态中,可以调整是否发送感知报文,或者调整发送感知报文的频率,还可以是调整发送的感知报文的频带或信息量,以使得触发设备可以根据覆盖范围内是否有目标物存在进行调整。
本申请实施例使得触发设备在调整发送感知报文的工作状态后,可以减少对空口资源的占用,触发设备可以根据覆盖范围内是否有目标物存在来调节发送感知报文的工作状态,从而实现多个触发设备的合理规划和调度,进而有效提高无线感知的能力和效率。
可以理解的是,对覆盖范围内有目标物存在的触发设备,本申请实施例可以提高其感知性能,对于覆盖范围内没有目标物存在的触发设备,本申请实施例可以降低其感知性能,从而达到减少对空口资源的占用,提高无线感知的能力和效率。
参照图4所示,在一实施例中,触发设备被配置为根据预设的时间周期间隔发送感知报文,上述步骤S103中还可以包括但不限于步骤S201至步骤S202。
步骤S201,在多个时间周期内,根据每个触发设备的多个信道状态信息,形成序列信息。
步骤S202,根据序列信息,判断对应的触发设备覆盖范围内是否有目标物存在,得到信道判断结果。
在一实施例中,触发设备按照预设的时间周期间隔发送感知报文,对某一触发设备来说, 其在第一时刻向接入点设备发送感知报文,并在时间达到预设的时间周期后,在第二时刻向接入点设备发送感知报文,触发设备循环发送感知报文的次数可以预先设置,即触发设备发送感知报文的时间周期的个数可以预先限定,并在这多个时间周期内,接入点设备可以根据每个触发设备所发送的感知报文得到对应的多个信道状态信息,并根据多个信道状态信息形成序列信息,可以理解的是,序列信息是针对某一触发设备的,序列信息是该触发设备累计多个时间周期内发送过来的感知报文所得到的多个信道状态信息的集合,接入点设备根据序列信息,可以判断对应的触发设备覆盖范围内是否有目标物存在,得到信道判断结果。当需要进行处理的触发设备有多个时,接入点设备可以得到多个不同的触发设备的序列信息。
可以理解的是,本申请实施例中接入点设备通过序列信息来计算得到信道状态结果,实现了根据触发设备多个不同时间周期的信道状态信息进行判断,例如,当时间周期有3个,即触发设备在连续3个时间周期内发送了3个感知报文给接入点设备,其发送的时刻分别是第一时刻、第二时刻和第三时刻,第一时刻、第二时刻和第三时刻之间两两时间间隔相同,且均等于时间周期的大小,接入点设备可以根据第一时刻、第二时刻和第三时刻得到的3个信道状态信息得到该触发设备的序列信息,并基于序列信息中的这3个信道状态信息进行处理,从而可以知道对应的触发设备覆盖范围内是否有目标物存在,得到信道判断结果。
可以理解的是,接入点设备可以根据序列信息中的多个信道状态信息进行处理,从而得到所需要的信道判断结果,接入点设备可以对多个信道状态信息赋予对应的权重,并根据赋予权重后的信道状态信息加权计算得到所需要的信道判断结果,又或者,可以将多个信道状态信息输入至预设的处理模型中,处理模型可以是神经网络模型或数学模型,从而计算得到所需要的信道判断结果,在此不做具体限制。
参照图5所示,在一实施例中,上述步骤S202之前,还可以包括但不限于步骤S301至步骤S302。
步骤S301,获取序列信息中各个信道状态信息之间的报文时间间隔。
步骤S302,当报文时间间隔与时间周期的大小不对应,对序列信息进行插值操作,以使插值后的报文时间间隔与时间周期的大小相对应。
在一实施例中,经过多个时间周期后,由于空口的阻塞或者其他原因,接入点设备收到的每个触发设备发送的感知报文可能会有缺失,感知报文的数量可能会与时间周期的数量不相同,或者序列信息中各个信道状态信息之间的报文时间间隔不均匀,为了解决这个问题,接入点设备对于每一个触发设备的序列信息进行插值,即对序列信息中的信道状态信息进行插值,避免了空口竞争导致的接收报文非均匀。
在一些实施例中,接入点设备可以获取序列信息中各个信道状态信息之间的报文时间间隔,对报文时间间隔进行判断,当报文时间间隔与时间周期的大小不对应,对序列信息进行插值操作,以使插值后的报文时间间隔与时间周期的大小相对应。
例如,当序列信息中各个信道状态信息对应的报文时间分别是1秒、2秒、3.2秒和4秒时,时间周期的大小为1秒,此时时间为3秒时应该有一个对应的信道状态信息,但是由于空口的阻塞或者其他原因,导致报文时间变成了3.2秒,因此本申请实施例可以对3秒时间上的信道状态信息进行插值,使得插值后的序列信息中的各个信道状态信息对应的报文时间分别为1秒、2秒、3秒和4秒。
又例如,当序列信息中各个信道状态信息对应的报文时间分别是1秒、2秒和4秒时, 时间周期的大小为1秒,此时时间为3秒时应该有一个对应的信道状态信息,但是由于空口的阻塞或者其他原因,导致2秒和4秒中间时间段缺失了一个,因此本申请实施例可以对3秒时间上的信道状态信息进行插值,使得插值后的序列信息中的各个信道状态信息对应的报文时间分别为1秒、2秒、3秒和4秒。
参照图6所示,在一实施例中,上述步骤S302之中还可以包括但不限于步骤S401至步骤S404。
步骤S401,获取待插值的目标信道状态信息的标准时间。
步骤S402,对序列信息中在标准时间外的信道状态信息进行反距离权重配置,并将不同权重的信道状态信息进行加权平均计算,得到目标信道状态信息,将目标信道状态信息添加到序列信息中。
步骤S403,或者,获取序列信息中标准时间之前的多个信道状态信息,并将多个信道状态信息进行加权平均计算,得到目标信道状态信息,将目标信道状态信息添加到序列信息中。
步骤S404,或者,获取序列信息中与标准时间对应时间间隔的信道状态信息,并作为插值后的目标信道状态信息,将目标信道状态信息添加到序列信息中。
在一实施例中,本申请实施例中可以根据不同的方式进行插值。例如,本申请实施例中定义每个感知报文发送的时间为标准时间,标准时间与对应的触发设备、对应的时间周期有关,对同一个触发设备来说,其在相邻的两个标准时间之间的时间间隔与时间周期的大小相等,在插值的过程中,接入点设备首先获取待插值的目标信道状态信息的标准时间,例如,在上述实施例中,当序列信息中各个信道状态信息对应的报文时间分别是1秒、2秒、3.2秒和4秒时,时间周期的大小为1秒,此时时间为3秒时应该有一个对应的信道状态信息,3秒则为对应的目标信道状态信息的标准时间,接入点设备需要向标准时间为3秒时插值一个信道状态信息作为目标状态信息。
例如,本申请实施例可以通过反距离加权来进行插值,目标信道状态信息的标准时间上接收到的信道状态信息,是其他时间的信道状态信息的加权平均,通过反距离权重配置,距离上述标准时间越远,则权重越小,反之,距离上述标准时间越近,则权重越大,将不同权重的信道状态信息进行加权平均计算,可以得到目标信道状态信息,将目标信道状态信息添加到序列信息中。
此外,本申请实施例还可以进行多次样条插值,在多次样条插值中,标准时间上的目标信道状态信息是其之前的多个信道状态信息加权平均处理后得到的,接入点设备可以获取序列信息中标准时间之前的多个信道状态信息,并将多个信道状态信息进行加权平均计算,得到目标信道状态信息,将目标信道状态信息添加到序列信息中,例如,本申请实施例可以获取标准时间之前的3个信道状态信息,对这3个信道状态信息赋予对应的权重,例如,可以设置这3个信道状态信息权重相同,又或者,设置越接近标准时间的信道状态信息的权重越大,在此不做具体限制,并通过对赋予权重后的3个信道状态信息进行加权平均计算后,可以得到所需要的目标信道状态信息。
此外,本申请实施例还可以获取序列信息中与标准时间对应时间间隔的信道状态信息,并作为插值后的目标信道状态信息,将目标信道状态信息添加到序列信息中,时间间隔可以预先设置,例如,将时间间隔设置为标准时间之前的最短时间间隔,或者标准时间之后的最短时间间隔,实现了获取距离标准时间最近的信道状态信息作为目标信道状态信息。
参照图7所示,在一实施例中,上述步骤S202之中还可以包括但不限于步骤S501至步骤S502。
步骤S501,计算序列信息的协方差矩阵,并根据协方差的对角元素是否大于门限值,确定对应的触发设备覆盖范围内是否有目标物存在,得到信道判断结果。
步骤S502,或者,将序列信息输入至预先训练好的神经网络模型中,得到神经网络模型的输出结果,并根据输出结果确定对应的触发设备覆盖范围内是否有目标物存在,得到信道判断结果。
在一实施例中,本申请实施例可以通过多种方式来计算得到信道判断结果,例如,本申请实施例中可以通过计算序列信息的协方差矩阵,计算序列信息中的多个信道状态信息的协方差矩阵,并当协方差存在对角元素大于门限值τ时,则认为对应触发设备的覆盖范围内有目标物存在,从而得到表征对应触发设备覆盖范围内有人存在的信道判断结果,又或者,当协方差存在对角元素小于门限值τ时,则认为对应触发设备的覆盖范围内没有目标物存在,从而得到表征对应触发设备覆盖范围内没有人存在的信道判断结果。
又例如,本申请实施例还可以根据预设的神经网络模型来得到信道判断结果。在一些实施例中,可以将序列信息输入至预先训练好的神经网络模型中,即将多个信道状态信息输入至预先训练好的神经网络模型中,神经网络模型对输入的数据进行处理,可以输出神经网络模型的输出结果,根据输出结果可以确定对应的触发设备覆盖范围内是否有目标物存在,从而得到信道判断结果,可以理解的是,神经网络模型可以预先根据样本中的多个样本序列信息或多个样本信道状态信息,与样本中的信道判断结果进行训练优化后得到,在此不做具体限制。
可以理解的是,当触发设备有多个时,接入点设备可以分别对多个触发设备进行计算,从而得到各个触发设备的信道判断结果。
在一实施例中,触发设备包括低频触发设备和高频触发设备,低频触发设备和高频触发设备均被配置为向接入点设备发送感知报文。
需要说明的是,本申请实施例中将触发设备分成了低频触发设备和高频触发设备,低频触发设备和高频触发设备之间的频率不同,如图2所示,本申请实施例中可以通过设置一个接入点设备提供网络接入,同时有不少于2个的触发设备与接入点设备连接,低频触发设备和高频触发设备工作的频段不同,其中,工作频率较低的低频触发设备的天线相对于接入点设备天线的直线距离,大于或等于工作频率较高的高频触发设备的天线相对于接入点设备天线的距离,低频触发设备和高频触发设备可以每隔一段时间向接入点设备发送感知报文,低频触发设备和高频触发设备也可以是一个可以同时工作在两个频段的802.11设备,此时的低频、高频以触发设备实际工作时的频率进行界定。可以理解的是,低频触发设备和高频触发设备均可以有多个,在此不做具体限制。
可以理解的是,低频触发设备的覆盖范围高于高频触发设备的覆盖范围,在同等功率下,无线感知的覆盖范围随着频率的降低而升高,所以较低频率触发设备的覆盖范围高于较高频率触发设备的覆盖范围,本申请实施例在用户位于远端时采用频率较低的链路增加覆盖,当用户位于近端则采用频率较高的链路提升识别性能,通过对多频触发设备进行合理的规划和调度,相比只采用单一频段的触发设备,可以提升感知算法的性能,提升感知算法的覆盖。
需要说明的是,本申请实施例中通过低频触发设备和高频触发设备实现多链路同时进行 收发,同时保证无线感知的高精度和高覆盖。
参照图8所示,在一实施例中,上述步骤S104之中还可以包括但不限于步骤S601至步骤S603。
步骤S601,根据高频触发设备的信道判断结果向高频触发设备发送配置信息,以使高频触发设备调整发送感知报文的工作状态。
步骤S602,根据高频触发设备的信道判断结果确定是否调整低频触发设备发送感知报文的工作状态。
步骤S603,若是,则根据低频触发设备的信道判断结果向低频触发设备发送配置信息,以使低频触发设备调整发送感知报文的工作状态。
在一实施例中,由于高频触发设备设置在靠近接入点设备的近端,因此,本申请实施例先对高频触发设备的信道判断结果向高频触发设备发送配置信息,以使高频触发设备调整发送感知报文的工作状态,随后是否调整远端低频触发设备发送感知报文的工作状态,需要进行判断,本申请实施例根据高频触发设备的信道判断结果确定是否调整低频触发设备发送感知报文的工作状态,当判断结果表征肯定时,则根据低频触发设备的信道判断结果向低频触发设备发送配置信息,以使低频触发设备调整发送感知报文的工作状态。
可以理解的是,本申请实施例中的无线感知方法,先对近端的高频触发设备进行调节,再根据高频触发设备中的信道判断结果来判断是否需要对远端的低频触发设备进行调节,通过这样的调节方式,使得本申请实施例在发现目标物处于近端时,优先提高近端高频触发设备的感知能力,再根据近端中高频触发设备的实际情况来判断是否对远端低频触发设备进行调节,在得到确定的结果后,再通过对远端的低频触发设备的调节同时提高了近端和远端的算法覆盖能力。
在一实施例中,本申请实施例根据高频触发设备的信道判断结果确定是否调整低频触发设备发送感知报文的工作状态,高频触发设备的信道判断结果包括对应的高频触发设备覆盖范围内有目标物存在,或者没有目标物存在,当近端存在覆盖范围内有目标物存在的高频触发设备,或者覆盖范围内有目标物存在的高频触发设备的数量较多时,可以确定不对低频触发设备进行调整,此时优先提高近端高频触发设备的感知能力,而当近端不存在覆盖范围内有目标物存在的高频触发设备,或者覆盖范围内有目标物存在的高频触发设备的数量较少时,可以确定对低频触发设备进行调整,以此实现了根据高频触发设备的信道判断结果来确定是否调整低频触发设备。
可以理解的是,本申请实施例中,对低频触发设备和高频触发设备的感知报文的收集是分别在各个时间周期内收集,在对感知报文进行处理,以确定是否根据其覆盖范围内是否有人来调节触发设备发送感知报文的工作状态时,是先对高频触发设备的感知报文进行处理并进行判断,待达到满足调节低频触发设备发送感知报文的工作状态的条件时,才对低频触发设备的感知报文进行处理,从而减少了设备的计算和处理压力,提高了无线感知的规划和调度能力,提高了设备的运行效率,有效提高了感知能力和效率。
参照图9所示,在一实施例中,上述步骤S602之中还可以包括但不限于步骤S701至步骤S702。
步骤S701,当所有高频触发设备的信道判断结果表征覆盖范围内没有目标物存在,则确定调整低频触发设备发送感知报文的工作状态。
步骤S701,当高频触发设备的信道判断结果表征覆盖范围内有目标物存在,确定不调整低频触发设备发送感知报文的工作状态,或者,根据覆盖范围内有目标物存在的高频触发设备的数量确定是否调整低频触发设备发送感知报文的工作状态。
在一实施例中,本申请实施例根据高频触发设备的信道判断结果确定是否调整低频触发设备发送感知报文的工作状态。在一些实施例中,当所有高频触发设备的信道判断结果表征覆盖范围内没有目标物存在,则确定调整低频触发设备发送感知报文的工作状态,此时说明近端的高频触发设备覆盖范围内均没有目标物存在,不需要提高近端高频触发设备的感知能力,因此可以确定对远端低频触发设备的调节。
此外,当高频触发设备的信道判断结果表征覆盖范围内有目标物存在,可以预先设置条件来判断是否调节远端的低频触发设备。在一些实施例中,可以是一旦存在一个高频触发设备覆盖范围内有目标物存在,则不再对远端的低频触发设备进行调节,以满足一定需求时对近端感知能力和效率提升的优先考虑。不仅如此,判断的条件还可以是根据覆盖范围内有目标物存在的高频触发设备的数量确定是否调整低频触发设备发送感知报文的工作状态,例如,当接入点设备预设一个第一数量阈值,用来对是否调节远端低频触发设备发送感知报文的工作状态进行判断,当覆盖范围内有目标物存在的高频触发设备的数量小于第一数量阈值,则说明近端需要调节的高频触发设备的数量在可控范围内,再对远端低频触发设备的调节不影响对空口资源的占用,因此确定可以对低频触发设备发送感知报文的工作状态进行调节,而当覆盖范围内有目标物存在的高频触发设备的数量大于第一数量阈值,说明通过提升近端高频触发设备的感知性能后,再提高远端的低频触发设备的感知性能会影响整个系统的感知能力,因此不再对远端低频触发设备进行调节。
参照图10所示,在一实施例中,上述步骤S104之中还可以包括但不限于步骤S801至步骤S802。
步骤S801,根据信道判断结果确定覆盖范围内有目标物存在的触发设备,向覆盖范围内有目标物存在的触发设备发送第一配置信息,以使触发设备提高发送感知报文的信息量。
步骤S802,或者,根据信道判断结果确定覆盖范围内没有目标物存在的触发设备,向覆盖范围内没有目标物存在的触发设备发送第二配置信息,以使触发设备减少或停止发送感知报文。
在一实施例中,在对触发设备进行发送感知报文的工作状态的调节过程中,当触发设备的信道判断结果确定覆盖范围内有目标物存在,接入点设备向覆盖范围内有目标物存在的触发设备发送第一配置信息,以使这些触发设备提高发送感知报文的信息量,从而提高了这些触发设备的感知性能,提升信道状态信息的信息量,有助于分析得到覆盖范围内的用户动作,而对信道判断结果确定覆盖范围内没有目标物存在的触发设备,接入点设备则向覆盖范围内没有目标物存在的触发设备发送第二配置信息,以使这些触发设备减少或停止发送感知报文,对这类触发设备来说,其覆盖范围内没有目标物存在,继续发送感知报文会占用空口资源,造成无线感知的性能降低,因此让这类触发设备减少或停止发送感知报文,可以有效减少其对空口资源的占用。
在一实施例中,上述步骤S101之前,还可以包括但不限于以下步骤:
分别向多个触发设备发送初始配置信息,以使触发设备接收初始配置信息后配置触发设备的工作频段为第一工作频段。
且,在上述步骤S801之中,还可以包括担不限于以下步骤:
向覆盖范围内有目标物存在的触发设备发送第一配置信息,以使触发设备将工作频段从第一工作频段提高到第二工作频段。
在一实施例中,本申请实施例在执行无线感知方法之前,先向所有的触发设备发送一个初始配置信息,以使得触发设备在接收到初始配置信息后配置自身的工作频段为第一工作频段,可以理解的是,第一工作频段是一个较低的工作频段,工作在这个频段下,可以节省触发设备的功率并减少对空口的占用,而对一类覆盖范围内有目标物存在的触发设备的调节时,接入点设备可以向其发送第一配置信息,触发设备在接收到第一配置信息后将工作频段从第一工作频段提高到第二工作频段。
例如,本申请实施例通过发送初始配置信息,初始化默认配置所有的触发设备工作在20MHz的工作频段,以节省触发设备功率和减少空口的占用,可以理解的是,对2.4G触发设备来说,其工作频段可以有20MHz或40MHz,对于5G触发设备来说,其工作频段可以有20MHz、40MHz或80MHz,可以理解的是,触发设备还可以工作在更高频段,在接入点设备对覆盖范围内有目标物的触发设备的调节时,需要帮助感知算法提升识别性能,提升对应的触发设备的工作频率从20MHz到较高频段,例如提高到40MHz或更高频段,以提升最终得到的信道状态信息的信息量,这是对感知性能的直接提升。
可以理解的是,本申请实施例通过提升带宽,即提升触发设备的工作频段,使得感知算法的性能也会提升,本申请实施例在发现处于近端时,动态的提升了带宽,在尽可能降低空口资源的占用的情况下,可以帮助提升感知算法的性能。
参照图11所示,在一实施例中,无线感知方法还可以包括但不限于步骤S901至步骤S902。
步骤S901,根据信道判断结果确定覆盖范围内有目标物存在的触发设备,并得到第三配置信息。
步骤S902,根据第三配置信息提高与覆盖范围内有目标物存在的触发设备的通信信息发送功率,或者根据第三配置信息降低接入点设备的增强的分布式信道访问参数。
在一实施例中,在得到触发设备覆盖范围内有目标物存在时,为了提高感知性能,本申请实施例还可以得到第三配置信息,并根据第三配置信息提高与覆盖范围内有目标物存在的触发设备的通信信息发送功率,或者根据第三配置信息降低接入点设备的增强的分布式信道访问(Enhanced Distributed Channel Access,EDCA)参数。可以理解的是,上述实施例中提高触发设备的工作频段,属于直接提升方法,本申请实施例中还可以通过间接提升方法,提升发送功率,或者降低EDCA参数,需要指出的是,其中直接提升方法可以在任何情况下,提升信道状态信息的信息量,而间接提升方法只能在信道较为拥塞下生效,在此不做具体限制。
需要说明的是,本申请实施例中的对感知性能的直接提升中,除了直接提升触发设备的工作频段,还可以降低触发设备发送感知报文的时间间隔,即,降低上述实施例中所描述的时间周期,从而也实现了感知报文信息量的提升,最终实现对信道状态信息的信息量的提升,提高了无线感知的性能。
参照图12所示,在一实施例中,上述步骤S101之中还可以包括但不限于步骤S1001至步骤S1002。
步骤S1001,分别确定各个触发设备一一对应的时间戳,并向各个触发设备发送时间戳, 以使触发设备根据对应的时间戳发送感知报文。
步骤S1002,分别接收多个触发设备根据对应的时间戳发送过来的感知报文。
在一实施例中,接入点设备为了避免多个触发设备出现同时发送感知报文的情况,避免造成空口阻塞,可以预先配置各个触发设备发送感知报文的时间。在一些实施例中,接入点设备分别确定各个触发设备一一对应的时间戳,并向各个触发设备发送时间戳,触发设备在接收到对应的时间戳后,根据对应的时间戳发送感知报文,使得接入点设备可以接收到多个触发设备根据对应的时间戳发送过来的感知报文,可以理解的是,不同的触发设备之间的时间戳并不相同,可以避免出现多个触发设备同时发送感知报文的情况。
在一实施例中,触发设备中包括低频触发设备和高频触发设备,参照图13所示,上述实施例中的时间戳根据以下步骤得到,可以包括但不限于步骤S1101至步骤S1105。
步骤S1101,分别获取低频触发设备和高频触发设备的设备数量。
步骤S1102,按照设备数量分别对低频触发设备和高频触发设备进行编号。
步骤S1103,获取低频触发设备和高频触发设备间隔发送感知报文的时间周期。
步骤S1104,根据设备数量、高频触发设备的编号、和时间周期,得到各个高频触发设备的时间戳。
步骤S1105,根据设备数量、低频触发设备的编号、末尾编号的高频触发设备的时间戳、和时间周期,得到各个低频触发设备的时间戳。
在一实施例中,接入点设备向每一个触发设备发送一个时间戳,根据低频触发设备和高频触发设备的设备数量,对每个触发设备依次进行编号,以使得触发设备根据不同的编号来依次发送感知报文,接入点设备还获取低频触发设备和高频触发设备间隔发送感知报文的时间周期,并根据设备数量、高频触发设备的编号、和时间周期,得到各个高频触发设备的时间戳,根据设备数量、低频触发设备的编号、末尾编号的高频触发设备的时间戳、和时间周期,得到各个低频触发设备的时间戳,使得各个触发设备的时间戳并不相同,可以理解的是,本申请实施例中优先让近端的高频触发设备发送感知报文,再在同一个时间周期内接收远端的低频触发设备发送的感知报文。
本申请实施例还可以定义第i个高频触发设备收到的时间戳为TH,i,定义第j个低频触发设备收到的时间戳为TL,i,每个触发设备从对应的时间戳开始,假设时间周期为T,则触发设备每隔T秒向接入点设备发送一个感知报文,其中,时间戳的计算方法是:

在上述公式(1)跟(2)中,将T秒分成了M+N份,M是低频触发设备的设备数量,N是高频触发设备的设备数量,T0是默认的初始时刻,在一实施例中,T0可以为0,这样可以表征多个触发设备发送的感知报文互相不冲突,N个较高频段触发设备会在TS,H,i,k=TH,i+kT进行发送,K为时间周期的数量,此时M个低频触发设备待机,随后再由低频触发设备发送感知报文,本申请实施例中称TS,H,i,k为上述实施例中的标准时间。
本申请实施例还提供了一种无线感知方法,应用于接触设备中,接触设备在此不再赘述,参照图14所示,本申请实施例中的无线感知方法包括但不限于步骤S1201至步骤S1202。
步骤S1201,向接入点设备发送感知报文,以使接入点设备根据感知报文得到对应的信 道状态信息,并根据信道状态信息判断对应的触发设备覆盖范围内是否有目标物存在,得到信道判断结果,接入点设备再根据信道判断结果得到配置信息。
步骤S1202,接收接入点设备发送的配置信息,并根据配置信息调整发送感知报文的工作状态。
在一实施例中,触发设备与接入点设备通信连接,触发设备可以向接入点设备发送感知报文,接入点设备在接收到感知报文后,根据感知报文分别得到对应的各个触发设备的信道状态信息,通过信道状态信息可以对对应的触发设备信号覆盖范围内的用户行为做出判断,本申请实施例可以根据信道状态信息判断对应的触发设备覆盖范围内是否有目标物存在,得到信道判断结果。在一些实施例中,信道判断结果有两种,包括对应的触发设备覆盖范围内有目标物存在的结果,或者对应的触发设备覆盖范围内没有目标物存在的结果,根据这两种结果,接入点设备可以得到配置信息,并向触发设备发送配置信息,触发设备在接收到配置信息后可以对自身进行控制,并调整触发设备本身发送感知报文的工作状态。
可以理解的是,触发设备调整发送感知报文的工作状态中,可以调整是否发送感知报文,或者调整发送感知报文的频率,还可以是调整发送的感知报文的频带或信息量,以使得触发设备可以根据覆盖范围内是否有目标物存在进行调整。
本申请实施例使得触发设备在调整发送感知报文的工作状态后,可以减少对空口资源的占用,触发设备可以根据覆盖范围内是否有目标物存在来调节发送感知报文的工作状态,从而实现多个触发设备的合理规划和调度,进而有效提高无线感知的能力和效率。
可以理解的是,对覆盖范围内有目标物存在的触发设备,本申请实施例可以提高其感知性能,对于覆盖范围内没有目标物存在的触发设备,本申请实施例可以降低其感知性能,从而达到减少对空口资源的占用,提高无线感知的能力和效率。
在一实施例中,向接入点设备发送感知报文的触发设备包括低频触发设备和高频触发设备。
需要说明的是,本申请实施例中将触发设备分成了低频触发设备和高频触发设备,对于某一触发设备来讲,其可以是低频触发设备和/或高频触发设备,低频触发设备和高频触发设备之间的频率不同,如图2所示,本申请实施例中可以通过设置一个接入点设备提供网络接入,同时有不少于2个的触发设备与接入点设备连接,低频触发设备和高频触发设备工作的频段不同,其中,工作频率较低的低频触发设备的天线相对于接入点设备天线的直线距离,大于或等于工作频率较高的高频触发设备的天线相对于接入点设备天线的距离,低频触发设备和高频触发设备可以每隔一段时间向接入点设备发送感知报文,低频触发设备和高频触发设备也可以是一个可以同时工作在两个频段的802.11设备。可以理解的是,低频触发设备和高频触发设备均可以有多个,在此不做具体限制。
可以理解的是,低频触发设备的覆盖范围高于高频触发设备的覆盖范围,在同等功率下,无线感知的覆盖范围随着频率的降低而升高,所以较低频率触发设备的覆盖范围高于较高频率触发设备的覆盖范围,本申请实施例在用户位于远端时采用频率较低的链路增加覆盖,当用户位于近端则采用频率较高的链路提升识别性能,通过对多频触发设备进行合理的规划和调度,相比只采用单一频段的触发设备,可以提升感知算法的性能,提升感知算法的覆盖。
在一实施例中,当本申请实施例中的无线感知方法应用于高频触发设备,接入点设备被配置为根据高频触发设备的信道判断结果得到配置信息;
当本申请实施例中的无线感知方法应用于低频触发设备,接入点设备被配置为根据其余高频触发设备的信道判断结果确定是否调整低频触发设备发送感知报文的工作状态,若是,则根据低频触发设备的信道判断结果得到配置信息。
在一实施例中,由于高频触发设备设置在靠近接入点设备的近端,因此,本申请实施例接入点设备先对高频触发设备的信道判断结果向高频触发设备发送配置信息,以使高频触发设备调整发送感知报文的工作状态,随后是否调整远端低频触发设备发送感知报文的工作状态,需要进行判断,本申请实施例根据高频触发设备的信道判断结果确定是否调整低频触发设备发送感知报文的工作状态,当触发设备为低频触发设备时,接入点设备根据与其连接的其余高频触发设备进行判断,当判断结果表征肯定时,则根据低频触发设备的信道判断结果向低频触发设备发送配置信息,以使低频触发设备调整发送感知报文的工作状态。
可以理解的是,本申请实施例中的无线感知方法,先对近端的高频触发设备进行调节,再根据高频触发设备中的信道判断结果来判断是否需要对远端的低频触发设备进行调节,通过这样的调节方式,使得本申请实施例在发现处于近端时,优先提高近端高频触发设备的感知能力,再根据近端中高频触发设备的实际情况来判断是否对远端低频触发设备进行调节,在得到确定的结果后,再通过对远端的低频触发设备的调节同时提高了近端和远端的算法覆盖能力。
在一实施例中,接入点设备还被配置为:当所有高频触发设备的信道判断结果表征覆盖范围内没有目标物存在,则确定调整低频触发设备发送感知报文的工作状态;当高频触发设备的信道判断结果表征覆盖范围内有目标物存在,确定不调整低频触发设备发送感知报文的工作状态,或者,根据覆盖范围内有目标物存在的高频触发设备的数量确定是否调整低频触发设备发送感知报文的工作状态。
在一实施例中,本申请实施例中接入点设备根据高频触发设备的信道判断结果确定是否调整低频触发设备发送感知报文的工作状态。在一些实施例中,当所有高频触发设备的信道判断结果表征覆盖范围内没有目标物存在,则确定调整低频触发设备发送感知报文的工作状态,此时说明近端的高频触发设备覆盖范围内均没有目标物存在,不需要提高近端高频触发设备的感知能力,因此可以确定对远端低频触发设备的调节。
此外,当高频触发设备的信道判断结果表征覆盖范围内有目标物存在,接入点设备可以预先设置条件来判断是否调节远端的低频触发设备。在一些实施例中,可以是一旦存在一个高频触发设备覆盖范围内有目标物存在,则不再对远端的低频触发设备进行调节,以满足一定需求时对近端感知能力和效率提升的优先考虑。不仅如此,判断的条件还可以是根据覆盖范围内有目标物存在的高频触发设备的数量确定是否调整低频触发设备发送感知报文的工作状态,例如,当接入点设备预设一个第一数量阈值,用来对是否调节远端低频触发设备发送感知报文的工作状态进行判断,当覆盖范围内有目标物存在的高频触发设备的数量小于第一数量阈值,则说明近端需要调节的高频触发设备的数量在可控范围内,再对远端低频触发设备的调节不影响对空口资源的占用,因此确定可以对低频触发设备发送感知报文的工作状态进行调节,而当覆盖范围内有目标物存在的高频触发设备的数量大于第一数量阈值,说明通过提升近端高频触发设备的感知性能后,再提高远端的低频触发设备的感知性能会影响整个系统的感知能力,因此不再对远端低频触发设备进行调节。
参照图15所示,在一实施例中,上述步骤S1202之中还可以包括但不限于步骤S1301至 步骤S1302。
步骤S1301,接收接入点设备发送的第一配置信息,以提高发送感知报文的信息量,其中,第一配置信息由接入点设备在触发设备覆盖范围内有目标物存在时得到。
步骤S1302,接收接入点设备发送的第二配置信息,并根据第二配置信息减少或停止发送感知报文,其中,第二配置信息由接入点设备在触发设备覆盖范围内没有目标物存在时得到。
在一实施例中,在对触发设备进行发送感知报文的工作状态的调节过程中,当触发设备的信道判断结果确定覆盖范围内有目标物存在,接入点设备向覆盖范围内有目标物存在的触发设备发送第一配置信息,触发设备接收到第一配置信息后,提高发送感知报文的信息量,从而提高了这些触发设备的感知性能,提升信道状态信息的信息量,有助于分析得到覆盖范围内的用户动作,而对信道判断结果确定覆盖范围内没有目标物存在的触发设备,接入点设备则向覆盖范围内没有目标物存在的触发设备发送第二配置信息,触发设备接收到第二配置信息后,减少或停止发送感知报文,对这类触发设备来说,其覆盖范围内没有目标物存在,继续发送感知报文会占用空口资源,造成无线感知的性能降低,因此让这类触发设备减少或停止发送感知报文,可以有效减少其对空口资源的占用。
在一实施例中,上述步骤S1201之前,还可以包括但不限于以下步骤:
接收接入点设备发送的初始配置信息,并根据初始配置信息配置工作频段为第一工作频段。
且,上述步骤S1301中,还可以包括担不限于以下步骤:
接收接入点设备发送的第一配置信息,并根据第一配置信息将工作频段从第一工作频段提高到第二工作频段。
在一实施例中,本申请实施例在执行无线感知方法之前,接入点设备先向所有的触发设备发送一个初始配置信息,以使得触发设备在接收到初始配置信息后配置自身的工作频段为第一工作频段,可以理解的是,第一工作频段是一个较低的工作频段,工作在这个频段下,可以节省触发设备的功率并减少对空口的占用,而对一类覆盖范围内有目标物存在的触发设备的调节时,接入点设备可以向其发送第一配置信息,触发设备在接收到第一配置信息后将工作频段从第一工作频段提高到第二工作频段。
例如,本申请实施例中接入点设备通过发送初始配置信息,初始化默认配置所有的触发设备工作在20MHz的工作频段,以节省触发设备功率和减少空口的占用,可以理解的是,对2.4G触发设备来说,其工作频段可以有20MHz或40MHz,对于5G触发设备来说,其工作频段可以有20MHz、40MHz或80MHz,可以理解的是,触发设备还可以工作在更高频段,在接入点设备对覆盖范围内有目标物的触发设备的调节时,需要帮助感知算法提升识别性能,提升对应的触发设备的工作频率从20MHz到较高频段,例如提高到40MHz或更高,以提升最终得到的信道状态信息的信息量,这是对感知性能的直接提升。
可以理解的是,本申请实施例通过提升带宽,即提升触发设备的工作频段,使得感知算法的性能也会提升,本申请实施例在发现处于近端时,动态的提升了带宽,在尽可能降低空口资源的占用的情况下,可以帮助提升感知算法的性能。
在一实施例中,当触发设备覆盖范围内有目标物存在,接入点设备还可以得到第三配置信息,接入点设备被配置为根据第三配置信息提高与覆盖范围内有目标物存在的触发设备的 通信信息发送功率,或者根据第三配置信息降低增强的分布式信道访问参数。
在一实施例中,在得到触发设备覆盖范围内有目标物存在时,为了提高感知性能,本申请实施例中接入点设备还可以得到第三配置信息,并根据第三配置信息提高与覆盖范围内有目标物存在的触发设备的通信信息发送功率,或者根据第三配置信息降低增强的EDCA参数。可以理解的是,上述实施例中提高触发设备的工作频段,属于直接提升方法,本申请实施例中接入点设备还可以通过间接提升方法,提升发送功率,或者降低EDCA参数,需要指出的是,其中直接提升方法可以在任何情况下,提升信道状态信息的信息量,而间接提升方法只能在信道较为拥塞下生效,在此不做具体限制。
需要说明的是,本申请实施例中的对感知性能的直接提升中,除了直接提升触发设备的工作频段,还可以降低触发设备发送感知报文的时间间隔,即,降低上述实施例中所描述的时间周期,从而也实现了感知报文信息量的提升,最终实现对信道状态信息的信息量的提升,提高了无线感知的性能。
参照图16所示,在一实施例中,上述步骤S1201之中还可以包括但不限于步骤S1401至步骤S1402。
步骤S1401,接收接入点设备发送的时间戳,其中,时间戳与触发设备一一对应。
步骤S1402,根据时间戳向接入点设备发送感知报文。
在一实施例中,接入点设备为了避免多个触发设备出现同时发送感知报文的情况,避免造成空口阻塞,可以预先配置各个触发设备发送感知报文的时间。在一些实施例中,接入点设备分别确定各个触发设备一一对应的时间戳,并向各个触发设备发送时间戳,触发设备在接收到对应的时间戳后,根据对应的时间戳发送感知报文,使得接入点设备可以接收到多个触发设备根据对应的时间戳发送过来的感知报文,可以理解的是,不同的触发设备之间的时间戳并不相同,可以避免出现多个触发设备同时发送感知报文的情况。
在一实施例中,触发设备为低频触发设备或高频触发设备,接入点设备分别与多个低频触发设备和高频触发设备连接;
当触发设备为高频触发设备,时间戳由接入点设备根据多个低频触发设备和高频触发设备的设备数量、高频触发设备的编号、和高频触发设备间隔发送感知报文的时间周期得到;
当触发设备为低频触发设备,时间戳由接入点设备根据设备数量、低频触发设备的编号、与接入点设备连接的末尾编号的高频触发设备的时间戳、和低频触发设备间隔发送感知报文的时间周期得到。
在一实施例中,接入点设备向每一个触发设备发送一个时间戳,根据低频触发设备和高频触发设备的设备数量,对每个触发设备依次进行编号,以使得触发设备根据不同的编号来依次发送感知报文,接入点设备还获取低频触发设备和高频触发设备间隔发送感知报文的时间周期,并根据设备数量、高频触发设备的编号、和时间周期,得到各个高频触发设备的时间戳,根据设备数量、低频触发设备的编号、末尾编号的高频触发设备的时间戳、和时间周期,得到各个低频触发设备的时间戳,使得各个触发设备的时间戳并不相同,可以理解的是,本申请实施例中优先让近端的高频触发设备发送感知报文,再在同一个时间周期内接收远端的低频触发设备发送的感知报文。
本申请实施例还可以定义第i个高频触发设备收到的时间戳为TH,i,定义第j个低频触发设备收到的时间戳为TL,i,每个触发设备从对应的时间戳开始,假设时间周期为T,则触发设 备每隔T秒向接入点设备发送一个感知报文,其中,时间戳的计算方法是:

在上述公式(1)跟(2)中,将T秒分成了M+N份,M是低频触发设备的设备数量,N是高频触发设备的设备数量,T0是默认的初始时刻,在一实施例中,T0可以为0,这样可以表征多个触发设备发送的感知报文互相不冲突,N个较高频段触发设备会在TS,H,i,k=TH,i+kT进行发送,K为时间周期的数量,此时M个低频触发设备待机,随后再由低频触发设备发送感知报文,本申请实施例中称TS,H,i,k为上述实施例中的标准时间。
除此之外,本申请实施例中提供了如下实施例,该实施例包括以下步骤:
1、初始化默认配置所有的触发设备工作在20MHz的工作频段,以节省触发设备功率和减少空口资源的占用。
2、在T0时刻,接入点设备向每一个触发设备发送一个时间戳,定义第i个高频触发设备收到的时间戳为TH,i,定义第j个低频触发设备收到的时间戳为TL,i,每个触发设备从时间戳开始,每隔T秒向接入点设备发送一个感知报文。其中,时间戳的计算方法是:

将T秒分成了M+N分,这样可以表征多个触发设备发送的感知报文互相不冲突,N个高频触发设备会在TS,H,i,k=TH,i+kT进行发送,M个低频触发设备待机,TS,H,i,k被称为标准时间。
3、接入点设备在每次接收到来自触发设备的感知报文时,进行信道估计,采集CSI信息,定义第k个来自第i个高频触发设备的CSI信息为HH,i,k,同时记录接收到这个感知报文的时间TR,H,i,k
4、经过K个T秒后,由于空口的阻塞或者其他原因,接入点设备收到的每个触发设备发送的感知报文可能没有K个,或者收到的报文时间间隔不为均匀的T秒,为了解决这个问题,接入点设备对于每一个触发设备的CSI信息进行插值,定义是第k个标准时间的插值后的数据。
插值的方法可以是:
(1)反距离加权法,即标准时间TS,H,i,k接收到的CSI,是其他时刻的CSI加权平均,距离标准时间越远,则权重越小,HH,i,k是来自第i个触发设备第k时刻的CSI数据,则插值的计算方法为:
其中wk是第k时刻的加权值。当k1<k2<k满足同时当k2>k3>k满足因此,距离k越远,则权重越小。
(2)三次样条插值,即标准时间TS,H,i,k接收到的CSI,是标准时间TS,H,i,k之前所有的CSI数据的加权平均,即:
其中,k小于3时,等于距离它最近的HH,i,k。当k大于三时,采用三次样条公式计算权重wk
(3)采用距离标准时间最近的CSI进行插值。
5、采用K个CSI判断第i个高频触发设备覆盖范围内是否有目标物,判决的方法可以是:
(1)计算K个CSI()的协方差矩阵,当协方差存在对角元素大于门限值τ,则认为高频触发设备的覆盖范围内有目标物。
(2)通过预训练的神经网络判决覆盖范围内是否有目标物存在。
所有N个高频触发设备都需要进行同样的判决,以确定其覆盖范围内是否有目标物存在。
6、调整所有在步骤5中判决为覆盖范围内有目标物的高频触发设备的参数以提升CSI的信息量,进而帮助感知算法提升识别性能,可以调整的参数分为如下的2个层次:
(1)直接提升方法:提升发送频段从20MHz到较高频段,或者降低发送间隔T;
(2)间接提升方法:提升发送功率,或者降低EDCA参数;
其中直接提升方法可以在任何情况下,提升CSI的信息量,而间接提升方法只能在信道较为拥塞下生效。
7、步骤5中如果高频触发设备覆盖范围内没有目标物存在,接入点设备要求高频触发设备停止发送感知报文,低频触发设备在TS,L,i,k=TL,i+kT时间处进行发送感知报文,通过覆盖范围内有目标物存在的高频触发设备的数量判断是否对低频触发设备进行调节,其处理过程与高频触发设备的处理过程相同,在此不再赘述。
8、采用步骤4中描述的CSI收集方法,持续获取来自高频触发设备或者低频触发设备的CSI数据,并送入后续处理。
