可选地，本申请实施例中的感知测量是基于毫米波实现的。对毫米波感知类型进行介绍：
图2是本申请一个示例性实施例提供的毫米波感知类型的示意图。如图2所示，图2的(a)为单基感知，参与感知的设备仅有一个，该设备通过自发(自行发送)感知PPDU和自收(自行接收)回响信号来感知环境，与传统的雷达工作方式相似。其中，自发自收指设备在发送感知PPDU时，会将该感知PPDU的发送方地址以及接收方地址均设置为该设备自身的地址。设备发送的感知PPDU经过环境的散射和/或反射，会形成回响信号，之后该设备可通过自身的地址接收到该回响信号，通过分析该回响信号能够实现对环境的感知。图2的(b)为双基感知，参与感知的设备有两个，其中一个设备发送感知PPDU，另一个设备接收回响信号来感知环境。图2的(c)为协作单基感知，参与感知的设备数量大于一个，每个设备通过自发感知PPDU和自收回响信号来感知环境，存在一个感知发起者控制所有其他设备以实现协作。图2的(d)为协作双基感知，参与感知的设备多于两个，即存在至少两对双基感知设备，每个发送设备(感知发送者)分别发送感知PPDU且由与其同组的接收设备(感知接收者)接收相应的回响信号，从而实现协作感知。图2的(e)为多基感知，参与感知的设备大于两个，一个发送设备发送感知PPDU，多个接收设备同时接收回响信号并同时完成环境感知。
对毫米波感知的流程进行介绍：
图3是本申请一个示例性实施例提供的毫米波感知的流程的示意图。如图3所示，该流程为毫米波感知的一般流程，从左向右依次为会话建立阶段、毫米波感知测量设置(方向性多吉比特(Directional Multi-Gigabit，DMG)Measurement setup)阶段和感知测量阶段。其中，感知测量阶段由多个感知测量突发组成，每个突发又由多个感知测量实例组成。突发与突发之间的时间间隔为突发间间隔，一个突发中相邻的感知测量实例之间的时间间隔为突发内间隔。图3中的MAC ADDR是指媒体接入控制(Medium Access Control，MAC)地址(address)，AID是指关联标识符，DMG测量设置ID(DMG Measurement setup Identity Document)是指毫米波感知测量设置标识，MS ID是指测量设置(Measurement Setup，MS)标识，突发ID是指突发标识，实例序列号(Sequential Number，SN)是指感知测量实例的标识，也可称为感知实例SN或感知实例ID。
在相关技术中的毫米波感知测量过程中，感知参与设备需要能够获得感知波束的角度信息，因此需要有关波束方位角和/或波束仰角的信息。但在相关技术的帧格式设计中存在无法准确指示波束方位角/波束仰角的问题，导致感知波束角度的坐标系指示不准确，影响感知流程的正常进行，本申请提供的感知测量方法可以有效解决这个问题。
图4是本申请一个示例性实施例提供的感知测量方法的流程图，本实施例以该方法由感知参与设备执行来举例说明，感知参与设备包括感知发起设备和感知响应设备中的至少一个。该方法包括：
步骤410：在感知测量过程中发送或接收携带有第一字段的帧，该第一字段用于指示坐标系设置相关的信息。
该坐标系设置相关的信息是与感知测量过程中所使用的坐标系有关的设置信息或配置信息。可选地，该坐标系设置相关的信息包括：参考坐标系的类型。
在一些实施例中，第一字段为坐标(coordinates)字段，该坐标字段用于指示参考坐标系的类型，参考 坐标系的类型包括如下至少之一：
·地球坐标系；
·任意一个STA的坐标系。
其中，任意一个STA的坐标系可以是感知发起设备的坐标系，或，感知响应设备的坐标系，或，感知发送设备的坐标系，或，感知接收设备的坐标系。
综上所述，本实施例提供的感知测量方法，通过在感知测量过程中发送或接收携带有第一字段的帧，能够使得感知参与设备之间设置或协商坐标系相关的信息，从而明确指示方位角/仰角的坐标系，确保响应感知流程的正常进行，保证感知测量的结果准确性。
1.1在感知会话建立阶段或在感知测量设置阶段，发送或接收携带有坐标字段的帧：
在一些实施例中，在感知测量过程中发送或接收携带有第一字段的帧，包括如下两个步骤中的至少一种：
在感知会话建立阶段，发送或接收携带有坐标字段的帧；
在感知测量设置阶段，发送或接收携带有坐标字段的帧。
感知测量过程至少可分为：基于触发帧(Trigger Based，TB)的感知测量过程(图5)、基于非触发帧(Based Non-Trigger，Based Non-TB)的感知测量过程(图6)，以及基于消极感知的感知测量过程(7)。其中，基于非触发帧也可称为非基于触发帧(Non-Trigger Based，Non-TB)。
图5是本申请一个示例性实施例提供的感知发起设备与感知响应设备建立感知测量流程的示意图，示例性的，感知发起设备为AP，感知响应设备为关联STA。
首先，在感知会话建立阶段，STA通过被动扫描或主动扫描获取到AP的无线网络信息，以便了解周围的无线网络分布情况。
·被动扫描：指STA在指定信道上被动监听AP周期广播的信标帧(Beacon frame)。其中，信标帧可以携带能力信息(Capability Information)、服务集标识(Service Set Identifier，SSID)等信息；
·主动扫描：指STA主动发送探测请求帧(Probe Request frame)至AP并且接收AP返回的探测响应帧(Probe Response frame)。其中，探测请求帧和探测响应帧可以携带能力信息、SSID、扩展能力(Extended Capability)等信息。上述不同帧中的能力信息是指发送当前帧的设备的能力信息。
其次，STA基于获取到的AP的无线网络信息建立与某一个AP的关联关系，以便获得无线网络的完全访问权，从而成为关联STA。
·STA首次连接一个AP时，STA会单播关联请求帧(Association Request frame)至AP并接收AP返回的关联响应帧(Association Response frame)。其中，关联请求帧可以携带能力信息、监听间隔(Listen Interval)、SSID、支持速率(Supported Rates)、服务质量能力(Quality of Service，QoS Capability)等信息；关联响应帧可以携带能力信息、状态码(Status Code)、关联标识符(Association Identify，AID)、扩展能力等信息。
·STA非首次连接一个AP时，STA会单播重关联请求帧(Reassociation Request frame)至AP并接收AP返回的重关联响应帧(Reassociation Response frame)。其携带信息与关联请求帧和关联响应帧类似。
再次，在感知测量设置阶段，基于上述环节中STA和AP交互的多种能力信息，AP发送感知测量设置请求帧(Sensing Measurement Set Request frame，MS Request frame)至关联STA并接收返回的感知测量设置响应帧(MS Response frame)，从而完成一个感知测量的设置。感知测量设置请求帧中可以携带测量帧(Null Data Physical layer Protocol Data Unit，NDP)带宽、NDP类型、上报类型等信息；感知测量设置响应帧中可以携带状态码等信息。
最后，在感知测量实例阶段，关联STA和AP之间建立感知测量实例(Measurement Instance)，开始发送和接收NDP并进行信道感知。
图6是本申请一个示例性实施例提供的感知发起设备与感知响应设备建立感知测量流程的示意图，在感知会话建立阶段，非关联STA与AP建立感知的流程与关联STA的流程相似，都使用信标帧、探测请求帧和探测响应帧来扫描AP的无线网络信息。
不同的是，非关联STA无需与AP建立关联关系，即无需向AP发送关联请求帧和接收关联响应帧，也无需向AP发送重关联请求帧和接收重关联响应帧。在感知测量设置阶段，非关联STA在扫描之后即可向AP发送感知测量设置查询帧(MS Query frame)来发起感知测量设置步骤，随后通过接收感知测量设置请求帧和发送感知测量设置响应帧来完成感知测量设置步骤。
最后，在感知测量实例阶段，非关联STA和AP之间建立感知测量实例，开始发送和接收NDP并进行信道感知。
图7是本申请一个示例性实施例提供的感知发起设备与感知响应设备建立感知测量流程的示意图，示例性的，感知发起设备为AP，感知响应设备为非关联STA。
STA在指定信道上被动监听AP周期广播的信标帧(Beacon frame)和宣告帧(Announce frame)来获取到AP的无线网络信息。之后STA向AP发送信息请求帧(Information Request)，AP收到后向STA发送信息响应帧(Information Response)。

其中，协议版本子字段占用B0-B1共2个比特，类型子字段占用B2-B3共2个比特，子类型子字段占用B4-B7共4个比特，前往DS子字段占用B8共1个比特，来自DS子字段占用B9共1个比特，更多片段子字段占用B10共1个比特，重试子字段占用B11共1个比特，功率调节子字段占用B12共1个比特，更多数据子字段占用B13共1个比特，受保护帧子字段占用B14共1个比特，+HTC子字段占用B15共1个比特。
关联请求帧、关联响应帧、重关联请求帧、重关联响应帧、探测请求帧、探测响应帧可以携带DMG感知波束描述符元素、DMG感知短能力元素中的至少一种。
在一些实施例中，宣告帧、信息请求帧、信息响应帧的帧结构如图10所示，都是行动(Action)帧结构，行动帧是管理帧的一种子类型，用于扩展管理帧。行动帧的帧体字段中的第一个字段是行动字段，其中的类别(Category)子字段和行动细节(Action Details)子字段用于指示不同行动帧的子类型。不同子类型的行动帧的帧体字段中含有的字段和元素各不相同。行动帧结构包括依次排列的：帧控制字段、时长字段、地址1字段、地址2字段、地址3字段、序列控制字段、HT控制字段、帧体字段、帧校验字段。其中，帧控制字段占用2个字节，时长字段占用2个字节，地址1字段占用6个字节，地址2字段占用6个字节，地址3字段占用6个字节，序列控制字段占用2个字节，HT控制字段占用0或4个字节，帧体字段占用字节数可变，帧校验字段占用4个字节。

为了解决感知波束角度的坐标系指示不准确的问题，本申请在DMG感知波束描述符元素中增加了坐标字段。
1.2.1.1实施例一：
坐标字段与N个波束描述符字段是同层级字段，用于指示DMG感知波束描述符元素中所有的波束方位角字段和波束仰角字段的参考坐标系。坐标字段取值为第一取值时，指示地球坐标系；坐标字段取值为第二取值时，指示任意一个STA坐标系。
示例性的，在DMG感知波束描述符元素中新增一个坐标字段，如图14所示，图14是本申请一个示例性实施例提供的DMG感知波束描述符元素的元素结构示意图，包括依次排列的：元素ID字段、长度字段、元素ID扩展字段、发送标识字段、坐标字段、波束描述符1字段至波束描述符N字段。其中，元素ID字段占用1个字节，长度字段占用1个字节，元素ID扩展字段占用1个字节，发送标识字段占用1个字节，坐标字段占用1个字节，波束描述符1字段至波束描述符N字段各自占用6个字节。
在一些实施例中，波束描述符1字段与图13中波束描述符1字段相同，此处不再赘述。
坐标字段指示所在的DMG感知波束描述符元素中所有波束方位角子字段和波束仰角子字段的参考坐标系，坐标字段可以取0-255之间任意两个值。示例性的，坐标字段取值1指示地球坐标系(比如，波束方位角＝0为北，波束仰角＝0为地平线)；坐标字段取值0指示任意一个STA坐标系。如果DMG感知短能力元素中的地球坐标字段取值为0，则该字段的取值唯一(仅为1或仅为0)且指示任意一个STA坐标系。
在不同的实施例中，坐标字段也可取值0指示地球坐标系；取值1指示任意一个STA坐标系，本申请对此不加以限定。
本实施例通过在DMG感知波束描述符元素中新增一个坐标字段，使得坐标字段指示所在的DMG感知波束描述符元素中所有波束方位角子字段和波束仰角子字段的参考坐标系，从而减少开销，统一指示方位角/仰角的坐标系，确保响应感知流程的正常进行，保证感知测量的结果准确性。

由于相关技术中现有的帧格式设计中存在尚未解决的问题，例如在并行模式的协作单基感知中，没有对单基PPDU的格式和长度做明确的规定，所以单基PPDU可能与感知测量报告帧发生重叠从而产生干扰，从而导致影响感知流程的正常进行，本申请提供的感知测量方法可以有效解决这个问题。
对毫米波协作单基感知测量实例进行介绍：
毫米波协作单基感知测量实例存在两种模式，一种为顺序模式，另一种为并行模式。示例性的，图26是本申请一个示例性实施例提供的毫米波协作单基感知测量的顺序模式实例的示意图，图27是本申请一个示例性实施例提供的毫米波协作单基感知测量的并行模式实例的示意图。
如图26和图27所示，顺序模式与并行模式的相同点在于：感知发起者在感知测量实例的初始阶段需要分别发送毫米波感知请求帧至每个感知响应者，而且每个感知响应者需要在短帧间隔(Short Interframe Space，SIFS)时间内回复一个毫米波感知响应帧至感知发起者。DMG感知请求也可称为RQ，DMG感知响应也可称为RSP。
如图26和图27所示，顺序模式与并行模式的不同点在于：顺序模式中，每个感知响应者依次自行发送且接收单基感知测量帧来感知环境，并在SIFS时间内发送感知测量报告帧至感知发起者。并行模式中，每个感知响应者同时发送且接收单基感知测量帧来感知环境，随后依次发送DMG感知测量报告帧(感知测量报告帧)至感知发起者。
需要说明的是，图26和图27中，在感知发起者或感知响应者对应的横线上方的格子，表示设备发送的帧，横线下方的格子(空白格)表示设备接收的帧，并且发送的帧和接收的帧之间是对应的。对于正中压在感知响应者对应的横线上的格子，表示感知响应者自发自收的帧，例如感知响应者自发自收的单基感知测量帧。例如，图26中感知发起者向感知响应者STA A发送了RQ(由感知发起者对应的横线上方的格子表示)，相应的，感知响应者STA A会接收到该RQ(由感知响应者STA A对应的横线下方的空白格子表示)。本申请的其它附图中的空白格的含义可参照上述说明，对此不再赘述。

由于在并行模式的协作单基感知中，没有对单基PPDU的格式和长度做明确的规定，所以单基PPDU可能与感知测量报告帧发生重叠从而产生干扰，如图29所示。图29是本申请一个示例性实施例提供的协作单基感知测量的并行模式的流程示意图。该流程由一个感知发起者(STA)和两个感知响应者(站点A，站点B)参与，包括以下过程(从左至右)：
(1)感知发起者发送DMG感知请求帧至站点A，其中设置“实例中STA数量”＝2，“PPDU数量”＝1，“STA ID”＝0；
(2)SIFS时间后，站点A回复DMG感知响应帧至感知发起者；
(3)SIFS时间后，感知发起者发送DMG感知请求帧至站点B，其中设置“实例中STA数量”＝2，“PPDU数量”＝1，“STA ID”＝1；
(4)SIFS时间后，站点B回复DMG感知响应帧至感知发起者；
(5)SIFS时间后，站点A和站点B同时分别自发自收1个单基感知测量帧从而感知环境；
(6)SIFS时间后，站点A发送DMG感知测量报告帧至感知发起者，上报感知测量的结果；
(7)SIFS时间后，感知发起者回复确认(Acknowledge，ACK)帧至站点A；
(8)SIFS时间后，感知发起者发送DMG感知上报轮询帧至站点B，触发站点B上报感知测量结果；
(9)SIFS时间后，站点B发送DMG感知测量报告帧至感知发起者，上报感知测量的结果；
(10)SIFS时间后，感知发起者回复ACK帧至站点B。
需要说明的是，上述(7)和(10)为可选步骤。上述示例中仅存在2个感知响应者，对于存在更多感知响应者的情况，可通过上述方法继续触发后续的感知响应者发送DMG感知测量报告帧。
如图29所示，在上述过程中，当站点B自发自收的单基感知测量帧(Monostatic PPDU)的长度大于站点A自发自收的单基感知测量帧的长度时，站点B自发自收的单基感知测量帧与站点A发送的DMG感知测量报告帧存在重叠，从而导致站点A与站点B之间产生干扰。
为了解决站点A与站点B之间产生干扰的问题，提供了一种感知测量方法，图30是本申请一个示例性实施例提供的感知测量方法的流程图，该方法由感知参与设备执行，包括：
步骤3010：在并行模式的协作单基感知过程中发送或接收携带有第二字段的帧，该第二字段用于指示单基PPDU的时长相关信息。
为了解决站点A与站点B之间产生干扰的问题，本申请提出了两种解决方案：
方案一：感知响应者主动将其所使用的单基PPDU的时长相关信息告知感知发起者，感知发起者基于这些信息依据一定的规则选择合适的DMG感知轮询帧的发送时刻；示例性的，感知响应者1和感知响应 者2告知感知发起者单基PPDU的时长分别为t1和t2，t1大于t2，那么感知发起者在时长t1后经过SIFS时间发送DMG感知轮询帧。示例性的，方案一中的单基PPDU的时长相关信息是指感知响应者发送单基PPDU的实际时长信息。
在并行模式的协作单基感知过程中，感知响应设备向感知发起设备发送携带有第二字段的帧，该帧为DMG感知测量设置响应帧或DMG感知响应帧；
在并行模式的协作单基感知过程中，感知发起设备接收感知响应设备发送的携带有第二字段的帧，该帧为DMG感知测量设置响应帧或DMG感知响应帧。
在方案一的实施例中，感知发起设备依据以下规则选择合适的DMG感知轮询帧的发送时刻：
在一个协作单基感知实例中，如果实例为并行模式，则感知发起设备必须在时长最长的单基PPDU发送结束之后不超过SIFS时间内发送第一个DMG感知轮询帧来触发感知响应设备上报感知测量结果。
方案二：感知响应者被动接收来自感知发起者的单基PPDU的时长配置信息，依据这些信息来发送合适的单基PPDU。同时，感知发起者也依据这些单基PPDU的时长配置信息来选择合适的DMG感知轮询帧的发送时刻。示例性的，感知发起者的单基PPDU的时长配置信息为t3，那么感知响应者1和感知响应者2发送的单基PPDU时长不能超过t3。示例性的，方案二中的单基PPDU的时长相关信息是指感知发起者要求的单基PPDU的最大发送时长，感知响应者发送的单基PPDU的实际发送时长不能超过感知发起者要求的单基PPDU的最大发送时长。
在并行模式的协作单基感知过程中，感知发起设备向感知响应设备发送携带有第二字段的帧，该帧为DMG感知测量设置请求帧或DMG感知请求帧；
在并行模式的协作单基感知过程中，感知响应设备接收感知发起设备发送的携带有第二字段的帧，该帧为DMG感知测量设置请求帧或DMG感知请求帧。
在方案二的实施例中，感知发起者依据以下规则选择合适的DMG感知轮询帧的发送时刻：
在一个协作单基感知实例中，如果该协作单基感知实例为并行模式，则感知响应者必须按照感知发起者的相关配置信息来发送符合要求的单基PPDU；
在一个协作单基感知实例中，如果该协作单基感知实例为并行模式，则感知发起者必须在时长最长的单基PPDU发送结束之后不超过SIFS时间内发送第一个DMG感知轮询帧来触发感知响应者上报感知测量结果。
