Description

一种信息传输方法及站点、接入点 技术领域
本发明涉及通信技术领域，尤其涉及一种信息传输方法及站点、接入点。
背景技术
无线保真(Wireless Fidelity，WiFi)技术是一种基于IEEE802.11系列标准的无线通信技术，具备WiFi接口的设备可以在2.4G/5GHz频段进行数据通信。目前WiFi技术已经被广泛用于家居家电、个人智能设备、办公网络、传感网络等场景中。当设备的WiFi接口开启侦听模式时，会不断探测空间中的WiFi消息，并通过识别WiFi消息的媒体访问控制(Media Access Control，MAC)头部分的地址字段来判断所接收的WiFi消息是否是指向自己的消息。传统的WiFi消息由于在发送设备采用正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)、二进制卷积码(Binary Convolutional Code，BCC)/低密度奇偶校验(Low-density Parity Check，LDPC)等，接收设备进行信号接收时需要执行快速傅里叶变换(Fast Fourier Transform，FFT)、前向纠错码(Forward Error Correction，FEC)译码等复杂信号处理过程，因而在接收设备的WiFi接口开启侦听时，会消耗较多的电量。对于电池供电的设备，如智能手机、平板、可穿戴设备(如手环、手表、眼镜、增强现实/虚拟现实(Augmented Reality/Virtual Reality，AR/VR)头盔等)、传感器设备等，其电能供应有限，对能耗要求较高，在目前制定的IEEE802.11ax标准中，在要求提高传输速率的同时，也要求设备做到尽可能省电。
为了降低功耗，IEEE802.11ba提出在配置传统WiFi接口的基础上，增加一个低功耗(Lower Power，LP)唤醒射频(Wake-up Radio，WUR)接口。由于WUR接口的消息接收和译码远比传统WiFi帧简单，其通常采用易于接收设备解调的调制方式如开关键控(On-Off Key，OOK)调制，接收设备可通过包络检波法判断接收信号承载的信息，因此，接收设备采用WUR接口相比使用WiFi接口在接收消息时更能够降低功耗。采用上述配置，目标设备的WiFi接口一般会处于休眠状态，其WUR接口处于清醒状态或间歇性清醒状态以等待接收唤醒消息，若目标设备的WUR接口接收到唤醒消息，该目标设备解析该唤醒消息并唤醒其自身的WiFi接口，然后通过自身的WiFi接口与发送设备进行数据通信。然而，在目标接收设备的WiFi接口处于休眠状态的情况下，还可能存在WiFi接口处于清醒状态的部分非目标设备，该部分的非目标设备可能会采用自身WiFi接口误接收并采用WiFi标准中规定的解析方式解析非发送给自身的唤醒消息直到校验失败，从而耗费大量能量，造成额外的接收功耗。

具体实施方式
本申请中所涉及的第一通信接口可以为WiFi接口，第二通信接口可以为WUR接口，其中，WiFi接口也可以是如长期演进(Long Term Evolution，LTE)接口等其它数据通信接口，用于数据通信的模块可统称为主通信接口(main radio)模块(802.11main radio，802.11主模块)，如LTE模块、WiFi模块，本发明为了表述方便，以WiFi模块及其相应的WiFi接口进行说明；用于设备唤醒的模块可统称为唤醒射频模块或WUR模块，对应用于设备唤醒接口为WUR接口，需要说明的是，本申请对上述各功能模块以及对应接口的名称不作具体限定。
本申请中所涉及的发送设备以接入点(Access Point，AP)为例，接收设备以站点(Station，STA)；目标设备是指所述WUR PPDU的目标接收设备，即指定作为接收所述WUR PPDU的设备，非目标设备是指非指定接收所述WUR PPDU的设备，为了表述方便，目标设备以目标接收STA，非目标设备以非目标接收STA为例进行说明。
请参见图1，图1为本发明一个实施例提供的一种基础设施基本服务集(Infrastructure Basic Service Set，Infrastructure BSS)的网络架构图，该网络中包括至少一个AP和至少一个STA，如接入点AP1和AP2，站点如STA1～STA9。其中，STA1～STA6属于BSS1，STA5～STA9属于BSS2。其中，AP从逻辑上可以包括WiFi接口(802.11main radio，802.11主模块)和WUR接口。对于802.11标准而言，802.11主模块常常为OFDM宽带发射机，其也可以产生窄带WUR唤醒信号，例如，将OFDM信号的部分子载波空置而仅在唤醒消息(Wake-up Radio Physical Layer Convergence Procedure(PLCP)Protocol Data Unit，WUR PPDU)对应的窄带上传输信号，从而产生窄带信号，因此AP实际上可以包括上述两个通信接口，也可以只包括WiFi接口。相应的，STA也可以包括WiFi接口和WUR接口。
请参见图2，图2为本发明一个实施例提供的一种AP与STA的通信示意图，如图2所示，AP包含一个802.11主模块，需要说明的是，AP在具体实现时也可以将802.11主模块和唤醒射频模块分别实现。由于802.11主模块和唤醒射频模块可使用相同的频段载波如2.4GHz进行信号传输，因此可以采用同一个天线进行信号发射，以节省成本和简化设备结构。若802.11主模块和唤醒射频模块采用不同的频带载波，例如分别采用5GHz和2.4GHz频段，则分别需要不同的天线进行信号发射。为了节省能量，STA的WiFi接口通常处于休眠状态而WUR接口通常处于清醒状态或间歇性清醒状态。AP向STA发送唤醒消息WUR PPDU，该 WUR PPDU用于唤醒目标接收STA的WiFi接口。
请参见图3-1，图3-1为本发明实施例提供的一种原始WUR PPDU的结构示意图，如图3-1所示，该原始WUR PPDU包括PHY Header部分和WUR Payload部分，其中，PHY Header部分包括传统802.11前导(L-preamble)即前短训练域(Legacy-Short Training Field，L-STF)、前长训练域(Legacy-Long Training Field，L-LTF)、前信令域(Legacy-Signal，L-SIG)字段。目标接收STA通过WUR接口接收到WUR Payload部分时，确定该WUR Payload为发送给自己的唤醒消息，可唤醒自身处于休眠状态的WiFi接口，然后该STA可采用WiFi接口与AP进行数据通信。
在IEEE802.11ax中，目前已定义了四种HE PPDU格式，包括高效率单用户物理层协议数据单元(High Efficiency Single User Physical Layer Protocol Data Unit，HE SU PPDU)，高效率多用户物理层协议数据单元(High Efficiency Multi User Physical Layer Protocol Data Unit，HE MU PPDU)，高效率扩展范围单用户物理层协议数据单元(High Efficiency Extended Range Single User Physical Layer Protocol Data Unit，HE ER SU PPDU)及高效率基于触发的物理层协议数据单元(High Efficiency Trigger Based Physical Layer Protocol Data Unit，HE trigger-based PPDU)。请参见图3-2～3-5，图3-2～3-5分别为HE SU PPDU、HE MU PPDU、HE ER SU PPDU和HE trigger-based PPDU的结构示意图。以图3-3为例，HE MU PPDU中包括L-STF、L-LTF、L-SIG、重复非高吞吐率信号域(Repeated Legacy-Signal，RL-SIG)、高效率信号A域(High Efficiency Signal-A，HE-SIG-A)、高效率信号B域(High Efficiency Signal-B，HE-SIG-B)、高效率短训练域(High Efficiency-Short Training Field，HE-STF)、高效率长训练域(High Efficiency-Long Training Field，HE-LTF)、数据Data和包延长(packet extendsion，PE)，图中如L-STF对应的8μs表示L-STF的时长，其它以此类推。图3-2、图3-4和图3-5相应描述请参考图3-3，在此不再赘述。
AP1通过第一通信接口发送WUR PPDU(假设STA1为目标接收STA)，由于无线信道的广播特性，该WUR PPDU可能会被除STA1之外的BSS1内的其它STA如STA2～STA6收到，也可以被相邻的BSS2内的STA如STA5～STA9收到。这些可收到WUR PPDU的STA中，包含已配置唤醒射频模块的处于休眠状态和清醒状态的STA以及未配置唤醒射频模块的STA。未配置唤醒射频模块的STA由于不存在WUR通信接口，其可以通过WiFi接口接收PHY Header部分以及WUR Payload部分，由于WUR Payload部分采用与传统WiFi不同的调制编码机制，因此该STA会解析失败，浪费处理资源及电量。而对于已配置唤醒射频模块的处于清醒状态的STA，也可能通过WiFi接口接收PHY Header部分和WUR Payload部分，若接受到非发送给自身的WUR PPDU，该STA可能会将WUR Payload部分以WiFi标准中规定的解析方式进行误解析直到校验失败，从而造成额外的接收功耗。
为了解决上述问题，参考图3-2～图3-5中的四种PPDU格式的部分或全部PHY Header字段，本申请对图3-1中原始WUR PPDU的结构进行了改进，设计出如图3-6所示的改进WUR PPDU。请参见图3-6，图3-6为本发明实施例中提供的一种改进WUR PPDU的结构示意图。该改进WUR PPDU包括PHY Header部分和载荷(WUR Payload)部分，其中，PHY Header部分除包括传统802.11前导(L-preamble)部分即L-STF、L-LTF、L-SIG之外，还可以包括RL-SIG和HE-SIG-A，还可以进一步包括HE-SIG-B。PHY Header部分用于同步、自动增益 控制(Automatic Gain Control，AGC)、信道估计、控制信息指示等，可以在20MHz(或20MHz的整数倍)带宽上采用OFDM方式发送，用于后向兼容，使得STA可据此判断当前消息为WiFi消息，从而选择相应的空闲信道评估(clear channel assessment，CCA)判决阈值。WUR Payload部分携带待发送给目标设备的唤醒射频信息，该唤醒射频信息可包含目标设备的WUR接口的标识信息(如WUR ID)或时间信息，用于目标接收STA根据该时间信息来唤醒WiFi接口或者使目标STA的WUR模块与AP保持同步。该唤醒射频信息还可以包含WUR preamble、MAC Header、帧体(Frame Body)、帧校验序列(Cyclical Redundancy Check，FCS)中的一种或者多种，当然也可能采用与上述命名不相同的字段命名表述。WUR Payload采用与PHY Header部分不同的调制方式，如OOK调制或者频移键控(Frequency-shift keying，FSK)调制，可以在相比PHY Header的传输带宽更窄的带宽上传输，例如2MHz信道、4MHz信道、5MHz信道等(传统WiFi最小带宽为20MHz)，使得接收端的能耗更小。
本发明实施例中，PHY Header中HE-SIG-A或者HE-SIG-B所携带的指示信息用于指示STA是否需要进一步接收或解析PHY Header之后的WUR Payload部分。对于WiFi接口处于休眠状态的目标接收STA，其可通过WUR接口接收WUR Payload，并从该WUR Payload中解析到自身的标识ID(如单播/多播/广播地址或者是单播/多播/广播ID)，确定该唤醒消息是发送给自己的，可唤醒自身的WiFi接口；对于WiFi接口处于清醒状态的非目标接收STA，通过WiFi接口接收到PHY Header，并根据PHY Header中HE-SIG-A或者HE-SIG-B所携带的指示信息判断不需要继续接收和/或解析PHY Header之后的WUR Payload部分，可以提前切换WiFi接口至休眠状态，进一步地，还可以根据PHY Header中的L-SIG中设置的L-LENGTH字段的长度确定休眠时间，从而达到为非目标设备的省电目的，具体请参考图4对应的实施例。
请参见图4，图4为本发明的一个实施例提供的一种信息传输方法的流程示意图。如图4所示，该方法是由接入点AP和站点STA共同执行的。本发明实施例提供的一种信息传输方法包括：S101～S107。
S101，AP生成唤醒射频的唤醒射频的协议数据单元WUR PPDU。
具体的，AP生成唤醒射频的WUR PPDU，所述WUR PPDU包括PHY Header和WUR Payload，所述PHY Header包括传统802.11前导(L-preamble)部分如L-STF、L-LTF、L-SIG字段，可包括RL-SIG、HE-SIG-A，还可进一步包括HE-SIG-B，其中，HE-SIG-A或HE-SIG-B携带指示信息，该指示信息用于指示STA是否需要进一步接收或解析PHY Header之后的WUR Payload部分。WUR Payload包括待发送给目标设备的唤醒射频信息，所述唤醒射频信息用于指示所述目标设备唤醒所述目标设备的第一通信接口，其中，第一通信接口为802.11主模块对应的WiFi接口。所述L-preamble中包括长度信息，所述长度信息用于指示所述WUR PPDU的持续时长或占用的字节数量。
S102，AP通过所述AP的第一通信接口发送所述WUR PPDU中的所述PHY Header。
相应的，STA通过所述STA的第一通信接口接收AP发送的WUR PPDU中的PHY Header。
具体的，AP通过第一通信接口即WiFi接口，发送所述WUR PPDU中的所述PHY Header。WiFi接口处于休眠状态的STA可能无法接收到PHY Header，而WiFi接口处于清醒状态的STA 能够通过自身的WiFi接口接收到AP发送的PHY Header，并解析该PHY Header以获得指示信息。
S103，STA通过所述STA的第一通信接口接收并解析PHY Header以获得指示信息。
S104，AP通过第一通信接口或第二通信接口发送所述WUR PPDU中的所述WUR Payload。
具体的，AP通过WiFi接口或WUR接口发送该WUR PPDU中的WUR Payload部分。其中，WUR Payload包括目标接收STA的唤醒射频信息，用于目标接收STA接收并解析该唤醒射频信息，并唤醒其WiFi接口。
S105，所述STA根据所述指示信息判断是否通过所述STA的所述第一通信接口或第二通信接口继续接收和/或解析所述WUR Payload。
具体的，STA可以根据所述指示信息判断是否通过所述STA的所述第一通信接口或第二通信接口继续接收和/或解析所述WUR Payload。其中，所述指示信息包括基本服务集颜色BSS color、上下行指示参数和目标设备的标识ID中的至少一种。
在一种可能的实施例中，所述指示信息为基本服务集颜色BSS color。请一并参见图4-1，图4-1为本发明实施例提供的改进WUR PPDU的第一结构示意图。如图4-1所示，WUR PPDU以使用HE SU PPDU的部分PHY Header字段为例进行说明。需要说明的是，在实际应用中，也可能使用前述的四种PPDU格式的部分或全部PHY Header字段，本发明并不以此为限。
在HE-SIG-A字段中，包含BSS color字段子域，该BSS color可用于发送该HE SU PPDU的设备所属BSS的标识，其中，BSS为AP与其关联的STA所组成的网络，故BSS Color也是网络标识。STA接收到WUR PPDU的PHY Header部分后，会认为接收到HE SU PPDU的PHY Header，并进一步判断接收到的PHY Header中的HE-SIG-A字段中的BSS Color值是否与自己所属网络的BSS Color匹配，若不匹配，则说明该HE SU PPDU是其它BSS中的PPDU，可以执行步骤S106，若匹配，则说明该HE SU PPDU是自身BSS中的PPDU，可以执行步骤S107。
本发明实施例中，当AP要发送WUR PPDU时，可以将WUR PPDU的PHY Header中的BSS color设置为一个预设值，该预设值可以使得非目标接收STA在接收到该PHY Header之后，判断该PHY Header的发送端不属于自身所属的BSS，从而不再继续接收或者解析AP后续发送的WUR PPDU的WUR payload，而进入休眠状态，从而达到省电的效果。在一种可选的实施例中，可以将BSS Color值设置为一个特殊值，例如，若BSS Color字段占用6个比特位，则可以设置BSS Color＝111111，或者设置为标准定义的其他值。该BSS Color值也可以动态设置为某个值，例如，STA对空间中的WiFi消息进行侦听，并记录OBSS的BSS Color值，然后在WUR PPDU的PHY Header的BSS Color字段设置任意一个未被记录过的BSS Color值即与记录的OBSS的BSS Color值不同的值。
在一种可能的实施例中，所述指示信息为上下行指示参数。请一并参见图4-2，图4-2为本发明实施例提供的改进WUR PPDU的第二结构示意图。如图4-2所示，WUR PPDU以使用HE SU PPDU的部分PHY Header字段为例进行说明。在HE-SIG-A字段中，包含UL/DL字段子域，该UL/DL字段可用于指示该WUR PPDU为上行PPDU还是下行PPDU，例如，当AP发送HE SU PPDU时，若设置UL/DL＝0，表示该HE SU PPDU为下行PPDU，若设置 UL/DL＝1，表示该HE SU PPDU为上行PPDU。AP发送HE SU PPDU，若STA接收到HE SU PPDU的PHY Header，通过解析获得UL/DL＝1，则判定该HE SU PPDU为上行PPDU，然而，对于STA只会接收下行PPDU，因此，STA将不再进行后续的HE SU PPDU的Payload部分的接收或者解析。即若所述上下行指示参数指示所述HE SU PPDU为上行PPDU，则所述STA确定不通过所述STA的第一通信接口或第二通信接口继续接收和/或解析所述WUR Payload。
在一种可能的实施例中，所述指示信息为目标设备的标识ID。请一并参见图4-3，图4-3为本发明实施例提供的改进WUR PPDU的第三结构示意图。如图4-3所示，以WUR PPDU使用HE MU PPDU的PHY Header为例进行说明，本发明实施例中，HE MU PPDU中的PHY Header还可以包括HE-SIG-B，进一步地，还可以包括,HE-STF和HE-LTF，其中，该HE-SIG-B中包含一段普通域Common Field和若干个用户域User Field。在各User Field域中携带所述目标设备的ID，其中，所述目标设备的ID为所述WUR payload的目标设备的第一通信接口或第二通信接口的ID，例如，目标设备的ID可以为由AP分配给所述目标设备的在第一通信接口上的标识ID，例如关联标识(Association Identifier，AID)，或者，目标设备的标识ID可以为所述目标设备的第一通信接口的接口地址或者其衍生值，例如MAC地址或者由MAC地址转化而得到的值，或者，目标设备的标识ID可以为所述目标设备在第二通信接口上的标识ID，例如，WUR ID或者WUR接口地址，上述仅为本发明实施例所列举的几个示例，目标设备的ID并不以此为限。为表述方便，本发明实施例采用在HE-SIG-B中的STA-ID字段设置目标设备的AID为例进行说明。具体地，AP可以参考HE MU PPDU的生成方法，将WUR PPDU的WUR Payload部分设置于一个或者多个资源单元(resource unit，RU)中，进一步地，当WUR PPDU使用HE MU PPDU的PHY Header时，AP可以在多个RU中分别设置多个窄带的WUR Payload。在未设置WUR Payload的RU中可以放置给其他设备的数据内容。当STA接收到所述HE MU PPDU的PHY Header后，若STA接收该PHY Header并判断出该PHY Header中的HE-SIG-B中所指示的STA-ID字段设置的AID与自身相应的AID不匹配，则确认该STA为非目标接收STA，执行步骤S106。若STA接收该PHY Header并判断该PHY Header中的HE-SIG-B中所指示的STA-ID字段设置的AID与自身相应的AID匹配，则确认该STA为目标接收STA，可以执行步骤S107。
S106，所述STA根据指示信息确定不接收和/或解析所述WUR Payload。
具体的，若判断出该STA为非目标接收STA，则可以根据指示信息确定不通过所述STA的第一通信接口或第二通信接口继续接收和/或解析所述WUR Payload，则不再继续接收或者解析AP发送的WUR Payload，可以提前切换WiFi接口至休眠状态。进一步地，非目标接收STA还可以根据PHY Header中的L-SIG中设置的L-LENGTH字段的长度确定休眠时间，从而达到为非目标设备的省电目的。
S107，所述STA根据指示信息确定接收和/或解析所述WUR Payload。
具体的，若判断出该STA为目标接收STA，则可以根据指示信息通过该目标接收STA的第二通信接口即WUR接口继续接收和/或解析所述WUR Payload，以获取唤醒射频信息，并唤醒其WiFi接口。
本发明实施例中，AP生成WUR PPDU，并通过第一通信接口发送WUR PPDU中的PHY Header，然后通过第一通信接口或第二通信接口发送所述WUR PPDU中的所述WUR Payload， STA通过第一通信接口接收PHY Header，并根据PHY Header的指示信息判断是否通过所述STA的所述第一通信接口或第二通信接口继续接收和/或解析所述WUR Payload，若否，则说明所述STA为非目标设备，确定不通过STA的第一通信接口或第二通信接口继续接收和/或解析所述WUR Payload，避免非目标设备因对非发送给自身的Payload部分的接收和/或解析而损失能量，达到非目标设备的省电目的。进一步的，非目标设备还可以根据PHY Header中的L-SIG中设置的L-LENGTH字段的长度确定休眠时间，从而进一步为非目标设备省电。
请参见图5，图5为本发明实施例提供的一种STA的模块化示意图。其中，所述STA1包括：接收单元11、判断单元12和第一确定单元13。
接收单元11，用于通过所述STA的第一通信接口接收接入点AP发送的唤醒射频的协议数据单元WUR PPDU中的物理头PHY Header，所述PHY Header包括指示信息，所述WUR PPDU包括所述PHY Header和唤醒射频载荷WUR Payload，所述WUR Payload携带待发送给目标设备的唤醒射频信息，所述目标设备是指所述WUR PPDU的目标接收STA；

在一种可能的实施例中，所述指示信息为基本服务集颜色BSS color；则所述第一确定单元13具体用于：若所述BSS color与所述STA的第一通信接口所属的BSS的BSS color不匹配，则确定不通过所述STA的第一通信接口或第二通信接口继续接收和/或解析所述WUR Payload。
在一种可能的实施例中，所述指示信息为上下行指示参数；所述若否，所述第一确定单元13具体用于：若所述上下行指示参数指示所述WUR PPDU为上行PPDU，则确定不通过所述STA的第一通信接口或第二通信接口继续接收和/或解析所述WUR Payload。
