具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
无线通信技术中，在IEEE802.11任务组中成立了802.11bf任务组，研究无线感知。其中无线感知一般应用于密集场景下的位置发现(例如，家庭环境及企业环境等)，近感探测和/或存在探测等应用场景中。图1示出了本公开实施例适用的一种无线感知通信系统的示意图。如图1所示，站点与AP之间进行无线通信。并且无线感知的流程可能是站点发起无线感知，AP响应者进行响应。
其中，本公开中涉及的站点可以理解为是无线局域网中的用户终端，该用户终端可以称为用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、物联网(Internet of Things，IoT)客户端或者车载设备等。本公开中AP指无线局域网用户终端接入网络的设备、路由器等。
图2示出了本公开实施例在AP控制下站点与站点之间进行无线感知的示意图。如图2所示，相关技术中，在AP控制下站点与站点之间进行无线感知的方式，可以参考标准中静默时间(Quiet Time Period，QTP)机制。图3A至图3B示出了本公开实施例静默时间机制的格式示意图。如图3A所示，包括信息元素ID，字节长度，信息元素ID扩展，控制，静默时间内容。其中Octets标识八位位组，variable表示变量。如图3B所示，包括对话框，静默时间抵消，静默时间持续时间，静默时间间隔，重复次数，特定服务标识符。其中Octets标识八位位组，variable标识变量。具体而言，支持QTP的站点向支持QTP的AP发送QTP请求，在QTP期间内进行站点与站点之间的通信。
但是，相关技术中虽然存在有QTP机制可以用于站点与站点之间的通信机制，但是，在一次进程中可能存在着一个发起者，多个响应者的情况。例如，在IEEE802.11bf中的流程，802.11bf一次进程可能存在一个发起者，并且存在多个响应者，此时，若使用QTP机制用于站点与站点之间的通信机制，则所有站点均为站点与站点之间通信的发起者，即可以理解为，每个站点都要发送QTP请求。因此，由QTP机制可以理解，在AP控制下支持WLAN sensing的站点与站点通信时，容易导致出现相互干扰的情况。
因此，本公开提供一种无线感知方法。
图4是根据一示例性实施例示出的一种无线感知方法的流程图。如图4所示，无线感知方法用于站点中，包括以下步骤。
在步骤S11中，确定无线感知周期请求帧。
在步骤S12中，发送无线感知周期请求帧。
在本公开实施例中，站点根据其支持的无线感知的具体应用确定无线感知周期请求帧。无线感知周期请求帧包括站点进行无线感知的第一周期信息元素，第一周期信息元素用于站点进行周期性无线感知。站点发送确定的无线感知周期请求帧。AP接收到站点发送的无线感知周期请求帧后，响应于接收的无线感知周期请求帧，向站点发送无线感知周期响应帧。站点接收AP发送的无线感知周期响应帧，且需要执行下述步骤。
图5是根据一示例性实施例示出的一种无线感知方法的流程图。如图5所示，无线感知方法还包括以下步骤。
在步骤S21中，接收无线感知周期响应帧。
在本公开实施例中，无线感知周期响应帧包括无线访问接入点AP的第二周期信息元素。
在步骤S22中，响应于第二周期信息元素与第一周期信息元素相同，确定周期性发起无线感知消息。
在本公开实施例中，站点确定接收的无线感知周期响应帧中包括的第二周期信息元素，并且将第二周期信息元素与站点的第一周期信息元素进行匹配。若第二周期信息元素与站点的第一周期信息元素相同，则确定AP同意站点的无线感知周期请求。此时，第二周期信息元素中状态码(status code)为响应，站点确定周期性发起无线感知消息。在本公开实施例中，AP发送的无线感知周期响应帧，可以是广播帧。第二周期信息元素中状态码(status code)为响应。
另一种方式，若AP不接受站点发送的无线感知周期请求帧，则在无线感知周期响应帧中确定与第一周期信息元素不相同的第二周期信息元素，此时，第二周期信息元素中状 态码(status code)为不响应。站点确定AP发送的无线感知周期响应帧中的第二周期信息元素不同于第一周期信息元素，则不进行周期性发起无线感知消息。
图6是根据一示例性实施例示出的一种无线感知方法无线感知周期请求帧的示意图。在本公开实施例中，无线感知周期请求帧包括的第一周期信息元素的格式如图6所示。在本公开实施例中，无线感知周期请求帧包括以下至少一项：
周期信息元素ID，字节长度，无线感知周期偏移量，无线感知持续时间，无线感知间隔，无线感知重复数量，连接信息。
其中，在本公开实施例中，无线感知周期偏移量(WLAN sensing period offset)基于第一个无线感知周期(WLAN sensing Period，WSP)和信标发送间隔时间(target beacon Transmission time，TBTT)确定。换言之，无线感知周期偏移量，可以设置为第一个无线感知周期(WSP)与以Tus表示的TBTT的偏移量。
无线感知持续时间(WLAN sensing duration)基于无线感知周期确定。换言之，无线感知持续时间可以设置为无线感知周期持续时间，其单位可以为32μs。当然对该单位的限定仅仅是为了举例说明，并不是对本公开的无线感知持续时间的具体限定。
无线感知间隔(WLAN sensing interval)基于连续无线感知周期之间发送的间隔确定。换言之，以两个连续无线感知周期为例，无线感知间隔可以设置为两个连续WSP开始之间的请求间隔。
无线感知重复数量(WLAN sensing repetition)基于无线感知周期请求帧数量确定。换言之，无线感知重复数量可以设置为无线感知周期请求帧数量。
在本公开一示例性实施例中，站点发送第一周期信息元素的次数可以根据无线感知重复数量确定。或者，站点发送第一周期信息元素的次数还可以根据无线感知可以实现的具体应用确定。其中无线感知可以实现的具体应用可以是标识支持位置发现，可以是标识动作检测，例如，近感探测(proximity detection)或存在探测(presence detection)。
在本公开实施例中，第一周期信息元素还可以包括站点执行无线感知的次数，用于标识站点在一个无线感知周期内执行无线感知的次数。其中，连接信息可以标识2.4GHz，5GHz、6GHz或60GHz等频带信息。需要说明的是，若第一周期信息元素包括有连接信息，则上述实施例中第一周期信息元素中的周期信息元素ID，字节长度，无线感知周期偏移量，无线感知持续时间，无线感知间隔以及无线感知重复数量均需要重复出现。
其中，第一周期信息元素和第二周期信息元素包括相同的信息元素，本公开为便于描述将站点发送的周期信息元素称为第一周期信息元素，将AP发送的周期信息元素称为第二周期信息元素。图7是根据一示例性实施例示出的一种无线感知方法无线感知周期响应 帧的示意图。无线感知周期响应帧中包括的第二周期信息元素的格式如图7所示。
在本公开实施例中需要理解的是，在站点发送无线感知周期请求帧，以及接受AP发送的无线感知周期响应帧之前，AP与站点进行初始关联的过程中，需要进行能力信息交互。站点发送第二信息，第二信息标识站点支持的无线感知能力信息，以告知AP站点支持的能力信息。AP根据接收到站点发送的无线感知能力信息确定站点支持的能力。AP发送第一信息，第一信息标识AP支持的无线感知能力信息，已告知站点其支持的无线感知能力信息，站点确定AP支持的无线感知能力信息。在本公开实施例中，站点可以在初始关联请求帧(association request)中携带第二信息，或者在欲关联请求帧(re-association request)中携带第二信息。AP可以在初始关联响应帧(association response)中携带第一信息，或者在欲关联响应帧(re-association response)中携带第一信息或信标帧中携带第一信息。
图8A至图8C是根据一示例性实施例示出的一种无线感知方法的能力信息元素格式示意图。在本公开实施例中，站点第二信息元素或者AP的第一信息元素的格式可以是如图8A所示的帧格式，或者是如图8B所示的帧格式。其中若第一信息或者第二信息的格式为图8B所示的帧格式中，则在图8B所示的帧格式包括的信息域中包括第一信息或第二信息，其信息域的格式如图8C所示，包括子元素ID，字节长度，支持的应用(例如，information1标识支持位置发现，information2标识支持近感探测或存在探测)。
本公开实施例提供的无线感知方法可以适用于站点与AP一对一通信的情况。若站点与AP确定周期性发起无线感知消息，则参与周期性发起无线感知消息的站点接收P2P消息帧，例如WLAN sensing initial doing request帧。不参与周期性发起无线感知消息的其他站点的无线感知设置其网络分配向量(Network Allocation Vector，NAV)为繁忙。当然，本公开实施例提供的无线感知方法也可以适用于站点与AP的其他情况。如果存在重传延迟值(backoff)，则确定将backoff在在进行周期性发起无线感知消息的线感知周期内进行递减。对于不支持无线感知的站点，则将不支持无线感知的站点的NAV设置为繁忙，并在进行周期性发起无线感知消息的线感知周期内进行递减。
基于相同/相似的构思，本公开实施例还提供一种无线感知方法。
图9是根据一示例性实施例示出的一种无线感知方法的流程图。如图9所示，无线感知方法用于无线访问接入点AP中，包括以下步骤。
在步骤S31中，接收无线感知周期请求帧。
在本公开实施例中，无线感知周期请求帧包括站点进行无线感知的第一周期信息元素，第一周期信息元素用于站点进行周期性无线感知。
站点根据其支持的无线感知的具体应用确定无线感知周期请求帧。无线感知周期请求帧包括站点进行无线感知的第一周期信息元素，第一周期信息元素用于站点进行周期性无线感知。站点发送确定的无线感知周期请求帧。AP接收到站点发送的无线感知周期请求帧后，响应于接收的无线感知周期请求帧，若确定接受无线感知周期请求帧，设置第二周期信息元素与第一周期信息元素相同。向站点发送无线感知周期响应帧。站点接收AP发送的无线感知周期响应帧，且需要执行下述步骤。
在本公开实施例中，无线感知周期响应帧包括无线访问接入点AP的第二周期信息元素。站点确定接收的无线感知周期响应帧中包括的第二周期信息元素，并且将第二周期信息元素与站点的第一周期信息元素进行匹配。若第二周期信息元素与站点的第一周期信息元素相同，则确定AP同意站点的无线感知周期请求。此时，第二周期信息元素中状态码(status code)为响应，站点确定周期性发起无线感知消息。在本公开实施例中，AP发送的无线感知周期响应帧，可以是广播帧。第二周期信息元素中状态码(status code)为响应。
另一种方式，若AP不接受站点发送的无线感知周期请求帧，则在无线感知周期响应帧中确定与第一周期信息元素不相同的第二周期信息元素，此时，第二周期信息元素中状态码(status code)为不响应。站点确定AP发送的无线感知周期响应帧中的第二周期信息元素不同于第一周期信息元素，则不进行周期性发起无线感知消息。

其中，在本公开实施例中，无线感知周期偏移量(WLAN sensing period offset)基于第一个无线感知周期(WLAN sensing Period，WSP)和信标发送间隔时间(target beacon Transmission time，TBTT)确定。换言之，无线感知周期偏移量，可以设置为第一个无线感知周期(WSP)与以Tus表示的TBTT的偏移量。
无线感知持续时间(WLAN sensing duration)基于无线感知周期确定。换言之，无线感知持续时间可以设置为无线感知周期持续时间，其单位可以为32μs。当然对该单位的限定仅仅是为了举例说明，并不是对本公开的无线感知持续时间的具体限定。
无线感知间隔(WLAN sensing interval)基于连续无线感知周期之间发送的间隔确定。换言之，以两个连续无线感知周期为例，无线感知间隔可以设置为两个连续WSP开始之间的请求间隔。
无线感知重复数量(WLAN sensing repetition)基于无线感知周期请求帧数量确定。换言之，无线感知重复数量可以设置为无线感知周期请求帧数量。
在本公开一示例性实施例中，站点发送第一周期信息元素的次数可以根据无线感知重复数量确定。或者，站点发送第一周期信息元素的次数还可以根据无线感知可以实现的具体应用确定。其中无线感知可以实现的具体应用可以是标识支持位置发现，可以是标识动作检测，例如，近感探测(proximity detection)或存在探测(presence detection)。
在本公开实施例中，第一周期信息元素还可以包括站点执行无线感知的次数，用于标识站点在一个无线感知周期内执行无线感知的次数。其中，连接信息可以标识2.4GHz，5GHz、6GHz或60GHz等频带信息。需要说明的是，若第一周期信息元素包括有连接信息，则上述实施例中第一周期信息元素中的周期信息元素ID，字节长度，无线感知周期偏移量，无线感知持续时间，无线感知间隔以及无线感知重复数量均需要重复出现。
其中，第一周期信息元素和第二周期信息元素包括相同的信息元素，本公开为便于描述将站点发送的周期信息元素称为第一周期信息元素，将AP发送的周期信息元素称为第二周期信息元素。图7是根据一示例性实施例示出的一种无线感知方法无线感知周期响应帧的示意图。无线感知周期响应帧中包括的第二周期信息元素的格式如图7所示。

图8A至图8C是根据一示例性实施例示出的一种无线感知方法的能力信息元素格式示意图。在本公开实施例中，站点第二信息元素或者AP的第一信息元素的格式可以是如图8A所示的帧格式，或者是如图8B所示的帧格式。其中若第一信息或者第二信息的格式为图8B所示的帧格式中，则在图8B所示的帧格式包括的信息域中包括第一信息或第二信息，其信息域的格式如图8C所示，包括子元素ID，字节长度，支持的应用(例如，information1标识支持位置发现，information2标识支持近感探测或存在探测)。
本公开实施例提供的无线感知方法可以适用于站点与AP一对一通信的情况。若站点 与AP确定周期性发起无线感知消息，则参与周期性发起无线感知消息的站点接收P2P消息帧，例如WLAN sensing initial doing request帧。不参与周期性发起无线感知消息的其他站点的无线感知设置其网络分配向量(Network Allocation Vector，NAV)为繁忙。当然，本公开实施例提供的无线感知方法也可以适用于站点与AP的其他情况。如果存在重传延迟值(backoff)，则确定将backoff在在进行周期性发起无线感知消息的线感知周期内进行递减。对于不支持无线感知的站点，则将不支持无线感知的站点的NAV设置为繁忙，并在进行周期性发起无线感知消息的无线感知周期内进行递减。
基于相同的构思，本公开实施例还提供一种无线感知装置。
可以理解的是，本公开实施例提供的无线感知装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。结合本公开实施例中所公开的各示例的单元及算法步骤，本公开实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能，但是这种实现不应认为超出本公开实施例的技术方案的范围。
