背景技术
随着无线业务日益增长，网络规模越建越大，设备能耗不断上升，无线接入网设备高能耗逐渐成为运营商运营成本(operating expense，OPEX)居高不下的主要原因之一。降低接入网设备的运行能耗，降低运营商的OPEX，是当前一个研究方向。
发明内容
本申请实施例提供一种节能方法及装置，以降低接入网设备的能耗，降低运营商的运营成本。
第一方面，提供一种节能方法，所述方法应用于基带单元，该方法的执体主体为基带单元，或基带单元中的部件(处理器、芯片或其它等)，包括：根据第一接收检测信号，确定第一射频单元的服务范围是否存在移动物体；所述第一射频单元的服务范围存在移动物体，所述第一射频单元工作在唤醒态；或者，所述第一射频单元的服务范围不存在移动物体，且所述第一射频单元为非监测射频单元，所述第一射频单元工作在休眠态；或者，所述第一射频单元的服务范围不存在移动物体，且所述第一射频单元为监测射频单元，所述第一射频单元工作在唤醒态；其中，所述监测射频单元在第一时间段的初始阶段工作在唤醒态，所述非监测射频单元在所述第一时间段的初始阶段工作在休眠态。
通过上述设计，接入网设备的射频单元中包括工作在唤醒态的第一射频单元。若在第一射频单元的服务范围内，检测到移动物体，则第一射频单元继续工作在唤醒态；若在第一射频单元的服务范围内，未检测到移动物体，且第一射频单元为非监测射频单元时，则将第一射频单元切换到休眠态，射频单元按需自适应节能，实现接入网设备的最大程度节能。
在一种设计中，所述第一射频单元工作在唤醒态，包括：启动或重启所述第一射频单元的定时器；在所述第一射频单元的定时器的运行期间，所述第一射频单元工作在唤醒态。
通过上述设计，工作在唤醒态的射频单元设置有定时器，在定时器的运行期间，对应的射频单元工作在唤醒态。在定时器过期后，对应的射频单元自动切换到休眠态。采用上述设计，当唤醒一个射频单元时，该唤醒的射频单元会在定时器过期后，自动切换到休眠态，进一步实现射频单元的节能。
在一种设计中，在所述第一射频单元工作在唤醒态时，还包括：唤醒所述第一射频单元的相邻射频单元中处于休眠态的射频单元；启动或重启所唤醒的相邻射频单元的定时器；在所述相邻射频单元的定时器的运行期间，所述相邻射频单元工作在唤醒态。
通过上述设计，当唤醒第一射频单元时，还唤醒第一射频单元的相邻射频单元。这主要是因为：当某个用户位于第一射频单元的服务范围时，随着用户移动，很可能会进入第一射频单元的相邻射频单元的服务范围，预先将第一射频单元的相邻射频单元唤醒，避免出现用户移动到相邻射频单元的服务范围时，相邻射频单元工作在休眠态，无法提供服务的问题，提供用户的服务体验。
在一种设计中，所述第一射频单元工作在休眠态，包括：在所述第一射频单元的定时器到期后，所述第一射频单元工作在休眠态。
在一种设计中，所述第一接收检测信号是由所述第一射频单元发送，且由第二射频单元接收的；或者，所述第一接收检测信号是由第二射频单元发送，且由所述第一射频单元接收的；或者，所述第一接收检测信号是由所述第一射频单元的第一天线发送，且由所述第一射频单元的第二天线接收的。
通过上述设计，接入网设备中的一个射频单元发送检测信号，另一个射频单元接收该检测信号。或者，接入网设备中的一个射频单元相连接的一个天线发送检测信号，同一个射频单元相连的另一个天线接收检测信号。该接收的检测信号可称为第一接收检测信号，该第一接收检测信号在空口传播的范围可 认为是射频单元的服务范围。通过对第一接收检测信号进行后续的雷达处理，可确定射频单元的服务范围内，即检测信号在空口传播的范围内，是否移在移动物体。该移动物体作为用户时，其手持的终端设备可处于连接态、空闲态或休眠态等。采用上述方法，可较准确的检测射频单元的服务范围内是否存在终端设备，从而有根据该检测结果，对相应的射频单元实现较精准的节能操作。
在一种设计中，所述根据第一接收检测信号，确定第一射频单元的服务范围是否存在移动物体，包括：根据所述第一接收检测信号，确定是否存在由移动物体引起的多普勒频移信号；存在由所述移动物体引起的多普勒频移信号，确定所述第一射频单元的服务范围内存在移动物体；或者，不存在由所述移动物体引起的多普勒频移信号，确定所述第一射频单元的服务范围不存在移动物体。
通过上述设计，通过对射频单元接收的检测信号，即第一接收检测信号，进行雷达处理，可确定射频单元的服务范围内是否存在移动物体。进一步，当检测到移动物体时，则第一射频单元工作在唤醒态，从而保证该移动物体有终端需要服务时，第一射频单元为其提供网络服务。
在一种设计中，所述第一射频单元的服务范围不存在连接态终端设备。
通过上述设计，可直接利用第一方面中的方法，进行节能操作。或者，可先确定第一射频单元的服务范围内是否存在连接态终端；在不存在连接态终端时，再根据第一接收检测信号，确定第一射频单元的服务范围内是否存在移动物体等操作。由于检测连接态终端的过程较简单，实现方式也有很多。当某个射频单元的服务范围内存在连接态终端时，可直接保持该射频单元工作在唤醒态，无需再执行第一方面的雷达相关的检测操作，进一步节省了接入网设备的能耗。
第二方面，提供一种检测移动物体的方法，所述方法应用于基带处理单元，该方法的执体主体为基带单元，或基带单元中的部件(处理器、芯片或其它等)，包括：根据第一接收检测信号，确定第一射频单元的服务范围是否存在移动物体；其中，所述第一接收检测信号是由所述第一射频单元发送，且由第二射频单元接收的；或者，所述第一接收检测信号是由第二射频单元发送，且由所述第一射频单元接收的；或者，所述第一接收检测信号是由所述第一射频单元的第一天线发送，且由所述第一射频单元的第二天线接收的。
通过上述设计，可确定第一射频单元的服务范围内是否存在移动物体。同时，移动物体为终端设备的用户，该终端设备的状态可为连接态、空闲态或非激活态等，从而实现对射频单元的服务范围内是否有终端设备的较准确检测。
在一种设计中，所述根据所述第一接收检测信号，确定所述第一射频单元的服务范围是否存在移动物体，包括:根据所述第一接收检测信号，确定是否存在由移动物体引起的多普勒频移信号；存在由所述移动物体引起的多普勒频移信号，确定所述第一射频单元的服务范围内存在移动物体；或者，不存在由所述移动物体引起的多普勒频移信号，确定所述第一射频单元的服务范围不存在移动物体。
通过上述设计，通过对射频单元接收的检测信号，即第一接收检测信号，进行雷达处理，可确定射频单元的服务范围内是否存在移动物体。当该移动物体为终端设备的用户时，可实现对射频单元的服务范围内是否存在终端设备的检测。射频单元的服务范围可认为是检测信号在空口中传播的范围。

接入网设备可以是基站(base station)、演进型基站(evolved NodeB，eNodeB)、发送接收点(transmission reception point，TRP)、第五代(5th generation，5G)移动通信系统中的下一代基站(next generation NodeB，gNB)、开放无线接入网(open radio access network，O-RAN)中的接入网设备、第六代(6th generation，6G)移动通信系统中的下一代基站、未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。接入网设备可以是宏基站(如图1中的110a)，也可以是微基站或室内站(如图1中的110b)，还可以是中继节点或施主节点等。本公开中对接入网设备所采用的具体技术和具体设备形态不做限定。
终端设备可以称为终端、用户设备(user equipment，UE)、移动台、移动终端设备等。终端设备可以广泛应用于各种场景中的通信，例如包括但不限于以下至少一个场景：设备到设备(device-to-device，D2D)、车物(vehicle to everything，V2X)、机器类通信(machine-type communication，MTC)、物联网(internet of things，IOT)、虚拟现实、增强现实、工业控制、自动驾驶、远程医疗、智能电网、智能家具、智能办公、智能穿戴、智能交通、或智慧城市等。终端设备可以是手机、平板电脑、带无线收发功能的电脑、可穿戴设备、车辆、无人机、直升机、飞机、轮船、机器人、机械臂、或智能家居设备等。本公开对终端设备所采用的具体技术和具体设备形态不做限定。
接入网设备和终端设备可以是固定位置的，也可以是可移动的。接入网设备和/或终端设备可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和人造卫星上。本公开对接入网设备和终端设备的应用场景不做限定。接入网设备和终端设备可以部署在相同的场景或不同的场景，例如，接入网设备和终端设备同时部署在陆地上；或者，接入网设备部署在陆地上，终端设备部署在水面上等，不再一一举例。
接入网设备和终端设备的角色可以是相对的，例如，图1中的直升机或无人机120i可以被配置成移动接入网设备，对于那些通过120i接入到无线接入网100的终端设备120j来说，终端设备120i是接入网设备；但对于接入网设备110a来说，120i是终端设备，即110a与120i之间是通过无线空口协议进行通信的。110a与120i之间也可以是通过接入网设备与接入网设备之间的接口协议进行通信的，此时，相对于110a来说，120i也是接入网设备。因此，接入网设备和终端设备都可以统一称为通信装置，图1中的110a和110b可以称为具有接入网设备功能的通信装置，图1中的120a-120j可以称为具有终端设备功能的通信装置。
接入网设备和终端设备之间的通信遵循一定的协议层结构。该协议层结构可以包括控制面协议层结构和用户面协议层结构。例如，控制面协议层结构包括无线资源控制(radio resource control，RRC)层、分组数据汇聚层协议(packet data convergence protocol，PDCP)层、无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理层等协议层的功能。例如，用户面协议层结构可以包括PDCP层、RLC层、MAC层和物理层等协议层的功能，在一种可能的实现中，PDCP 层之上还可以包括业务数据适配协议(service data adaptation protocol，SDAP)层。
在不同的场景下，接入网设备有不同的结构，对接入网设备的结构进行示例性说明：
1、基带单元和射频单元。
接入网设备包括基带单元和射频单元。基带单元和射频单元物理上可以设置在一起，也可以物理上分开设置，即分布式接入网设备。基带单元和射频单元的接口可以为光接口，两者之间可通过光纤传输数据。
基带单元，主要用于进行基带信号处理，对接入网设备进行控制等。对基带信号处理包括以下一项或多项：信道编码，复用，调制，扩频，或对载波的功率限幅等。示例性，基带单元由一个或多个单元构成，多个单元可共同支持单一接入制式的无线接入网，或者支持不同接入制式的无线接入网。
射频单元，主要用于对射频信号的收发、以及射频信号与基带信号的转换。射频单元的工作原理是将基带信号下行经变频、滤波、放大后通过发送滤波传到天馈。可选的，射频单元中也可以实现部分基带功能，例如包括以下一项或多项：快速傅里叶变换(fast fourier transform，FFT)变换/快速傅立叶反变换(inverse fast fourier transformation，iFFT)变换、或波束赋形等。
在本公开中，对接入网设备的结构不作限制。例如，接入网设备的结构为：室外宏站的基带单元(base band unit，BBU)+射频拉远单元(remote radio unit，RRU)+天线、或BBU+有源天线单元(active antenna unit，AAU)。或者，接入网设备的结构为：室内传统的BBU+RRU+分布天线、或新型数字化室内的BBU+射频拉远单元集线器(remote radio unit hub，RHUB)+微型射频拉远单元(pico remote radio unit，pRRU)等。在上述结构中，接入网设备的结构可归结为：基带单元(BBU)+射频单元(AAU或RRU)等。
如图2所示，说明室内覆盖技术中，接入网设备的三层结构：BBU+RHUB+pRRU。
BBU：分布式接入网设备的主要组成部分。主要完成以下一项或多项功能：信号的基带处理(如信道编解码、调制解调等)、提供传输管理以及接口、管理无线资源、或提供时钟信号等。PBUB：提供BBU和pPPRU之间的接口的汇聚功能，并给pRRU提供远程供电。其中，该接口可以为公共无线接口(common public radio interface，CPRI)或者其他可能的前传接口，不予限制。pRRU：用于实现射频信号处理等。
其中，一个BBU连接一个或多个PHUB，一个PHUB连接一个或多个pRRU。其工作过程包括：在下行传输中，BBU将下行信号发送给PHUB，PHUB与pRRU之间通过网线连接。PHUB将下行信号分发给各个pRRU。各个pRRU将下行信号处理为射频信号之后，通过射频馈线、合/分路器、天线等传输设备将射频信号接入室内。在上行传输中，室内的终端设备将上行信号发送给pRRU，各个pRRU将上行信号发送给PHUB，PHUB对上行信号进行汇聚，传输给BBU。
2、集中单元(central unit，CU)和分布单元(distributed unit，DU)。
接入网设备包括CU和DU。多个DU可以由一个CU控制。作为示例，CU和DU之间的接口可以称为F1接口。其中，控制面(control panel，CP)接口可以为F1-C，用户面(user panel，UP)接口可以为F1-U。本公开不限制各接口的具体名称。CU和DU可以根据无线网络的协议层划分：比如，PDCP层及以上协议层的功能设置在CU，PDCP层以下协议层(例如RLC层和MAC层等)的功能设置在DU；又比如，PDCP层以上协议层的功能设置在CU，PDCP层及以下协议层的功能设置在DU，不作限制。
上述对CU和DU划分的处理功能按照协议层的划分仅仅是一种举例，也可以按照其它的方式进行划分。例如，可以将CU和DU划分为具有更多协议层的功能，又例如将CU或DU还可以划分为具有协议层的部分处理功能。在一种设计中，将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。在另一种设计中，还可以按照业务类型或者其他系统需求对CU或者DU的功能进行划分，例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。在另一种设计中，CU也可以具有核心网的一个或多个功能。示例性的，CU可以设置在网络侧方便集中管理。在另一种设计中，将DU的无线单元(radio unit，RU)拉远设置。可选的，RU可以具有射频功能。
可选的，DU和RU可以在物理层(physical layer，PHY)进行划分。例如，DU可以实现PHY层中的高层功能，RU可以实现PHY层中的低层功能。
例如，PHY层的高层功能包括以下一项或多项：前馈纠错(forward error correction，FEC)编码/解码、加扰、或调制/解调。PHY层的低层功能包括以下中的一项或多项：快速傅里叶变换(fast fourier transform，FFT)变换/快速傅立叶反变换(inverse fast fourier transformation，iFFT)变换、数字波束赋形、或物理随机接入信道(physical random access channel，PRACH)的提取和滤波等。
再例如，用于发送时，PHY层的功能可以包括以下至少一项：添加循环冗余校验(cyclic redundancy check，CRC)码、信道编码、速率匹配、加扰、调制、层映射、预编码、资源映射、物理天线映射、或射频发送功能。用于接收时，PHY层的功能可以包括以下至少一项：CRC校验、信道解码、解速率匹配、解扰、解调、解层映射、信道检测、资源解映射、物理天线解映射、或射频接收功能。其中，PHY层中的高层功能可以包括PHY层的一部分功能，例如该部分功能更加靠近MAC层，PHY层中的低层功能可以包括PHY层的另一部分功能，例如该部分功能更加靠近射频功能。例如，PHY层中的高层功能可以包括添加CRC码、信道编码、速率匹配、加扰、调制、和层映射，PHY层中的低层功能可以包括预编码、资源映射、物理天线映射、和射频发送功能；或者，PHY层中的高层功能可以包括添加CRC码、信道编码、速率匹配、加扰、调制、层映射和预编码，PHY层中的低层功能可以包括资源映射、物理天线映射、和射频发送功能。例如，PHY层中的高层功能可以包括CRC校验、信道解码、解速率匹配、解码、解调、和解层映射，PHY层中的低层功能可以包括信道检测、资源解映射、物理天线解映射、和射频接收功能；或者，PHY层中的高层功能可以包括CRC校验、信道解码、解速率匹配、解码、解调、解层映射、和信道检测，PHY层中的低层功能可以包括资源解映射、物理天线解映射、和射频接收功能。
RU可以和终端设备通过射频信号进行通信。CU和DU可以包括在基带单元(baseband unit，BBU)中。BBU或DU与RU之间的接口可以称为前传接口。
示例性的，CU的功能可以由一个实体来实现，或者也可以由不同的实体来实现。例如，可以对CU的功能进行进一步划分，即将控制面和用户面分离并通过不同实体来实现，分别为控制面CU实体(即CU-CP实体)和用户面CU实体(即CU-UP实体)。该CU-CP实体和CU-UP实体可以与DU相耦合，共同完成接入网设备的功能。
可选的，上述DU、CU、CU-CP、CU-UP和RU中的任一个可以是软件模块、硬件结构、或者软件模块+硬件结构，不予限制。其中，不同实体的存在形式可以是不同的，不予限制。例如DU、CU、CU-CP、CU-UP是软件模块，RU是硬件结构。这些模块及其执行的方法也在本公开的保护范围内。
接入网设备的结构包括：CU、DU和RU。如图3所示，在一种设计中，接入网设备中包括近实时接入网智能控制(RAN intelligent controller，RIC)模块、CU、DU和RU等。可选的，接入网设备之外还包括非实时RIC。RIC为接入网设备的智能控制器，用于收集网络信息，执行网络优化等任务。或者，将图3中的CU分离为CU-CP和CU-UP。如图4所示，接入网设备的结构包括近实时RIC、CU、DU和RU等。
在本公开中，接入网设备中具有实现射频功能的单元。例如，当接入网设备的结构包括基带单元和射频单元时，该单元为射频单元。或者，当接入网设备的结构包括CU、DU和RU时，该单元为RU。为了便于描述，下文将具有射频功能的单元为射频单元为例。
在本公开中，用于实现射频单元的功能的装置可以是射频单元；也可以是能够支持射频单元实现该功能的装置，例如芯片系统、硬件电路、软件模块、或硬件电路加软件模块，该装置可以被安装在射频单元中或可以与射频单元匹配使用。在本公开中，芯片系统可以由芯片构成，也可以包括芯片和其他分立器件。为了便于描述，下文以用于实现射频单元的功能的装置是射频单元为例，描述本公开提供的技术方案。
在本公开中，接入网设备中具有实现基带功能的单元。例如，当接入网设备的结构包括：基带单元和射频单元时，实现基带功能的单元为基带单元。或者，当接入网设备的结构包括：CU、DU和RU时，实现基带功能的单元为CU和/或DU等，例如为BBU。为了便于描述，下文以用于实现基带功能的单元为基带单元为例。
在本公开中，用于实现基带单元的功能的装置可以是基带单元；也可以是能够支持基带单元实现该功能的装置，例如芯片系统、硬件电路、软件模块、或硬件电路加软件模块，该装置可以被安装在基带单元中或可以与基带单元匹配使用。为了便于描述，下文以用于实现基带单元的功能的装置是基带单元 为例，描述本公开提供的技术方案。
在新空口(new radio，NR)中，终端设备的状态包括连接(connected)态、空闲(idle)态和非激活(Inactive)态等，连接态也可称为激活(active)态。其中，空闲态是指终端设备在小区中完成驻留，但是未进行随机接入时所处的状态。通常在终端设备开机或RRC释放之后，终端设备进入空闲态。与空闲态相对应的是连接态，连接态是指终端设备完成随机接入，并建立RRC连接，且该RRC连接未释放时所处的状态。在连接态，终端设备可以与接入网设备进行数据传输。Inactive态是连接态与空闲态之间的状态。在Inactive态下，空口的用户面被暂停(suspend)，无线接入网(radio access network，RAN)与核心网(core network，CN)之间的用户面承载和控制面承载被维护。当终端设备发起寻呼或业务请求时，可以激活空口的用户面承载，并重用已有的RAN-CN之间的用户面承载和控制面承载。相较于空闲态，Inactive态保留了NG接口(NG接口为接入网与核心网间的接口)以及终端设备的上下文，终端设备在快速的恢复空口的连接之后，可以马上进行数据传输。
在本公开中，接入网设备包括基带单元和射频单元。基带单元通过射频单元接收的检测信号，确定射频单元的服务范围内是否存在移动物体。若存在移动物体，则表示该射频单元的服务范围内存在移动物体，则该射频单元工作在唤醒态；否则该射频单元工作在休眠态，从而实现接入网设备的节能。
在一种节能方案中，通过测量射频单元的参考信号接收功率(reference signal received power，RSRP)，确定射频单元的服务范围内是否存在连接态终端。例如，当测量的射频单元的RSPR大于或等于第一门限时，则确定射频单元的服务范围内存在连接态终端，射频单元工作在唤醒态；当测量的射频单元的RSRP小于第一门限时，则确定射频单元的服务范围内不存在连接态终端设备，射频单元工作在休眠态。缺点如下：由于连接态终端设备，向外发送参考信号。因此射频单元通过测量RSRP，确定射频单元的服务范围是否存在连接态终端。对于射频单元的服务范围内是否存在空闲态和/或非激活态终端设备，不能实现有效的检测。采用上述方案，可能导致某个射频单元被关闭，工作在休眠态，但其服务范围内存在空闲态和/或非激活态终端设备，终端设备的服务体验较差。
此外，对于空闲态终端设备，可通过改变接入网设备的跟踪区编码(tracking area code，TAC)，促使空闲态终端设备发起更新跟踪区(tracking area，TA)的过程，从而使接入网设备确定某个射频单元的服务范围内是否存在空闲态终端设备。该方案只有确定射频单元的服务范围内是否存在空闲态终端设备，对于非激活态终端设备的检测，并没有相关的解决方案。
在本公开中，根据射频单元接收的检测信号，确定射频单元的服务范围内是否存在移动物体。当移动物体为用户时，该用户的终端设备无论处于连接态、非激活态或空闲态等何种状态，只要该用户移动，则在本申请实施的方案中均能检测到。进而根据射频单元的服务范围内是否检测到移动物体，进行节能操作，从而避免出现在射频单元的服务范围内存在空闲态和/或非激活态终端设备时，关闭该射频单元服务的情况，提高终端设备的服务体验。
下面结合附图，说明本公开提供的节能方法，如图5所示，该方法包括：
接入网设备中包括基带单元和至少一个射频单元。该至少一个射频单元中的一个射频单元称为第一射频单元，第一射频单元工作在唤醒态。图5流程中的方法以对第一射频单元执行节能操作为例。可以理解的是，接入网设备中的很多单元均可执行图5的流程。在下文描述中，以基带单元作为图5流程的执行主体为例。
步骤501：基带单元根据第一接收检测信号，确定第一射频单元的服务范围是否存在移动物体。
例如，基带单元根据所述第一接收检测信号，确定是否存在由移动物体引起的多普勒频移信号；如果存在由移动物体引起的多普勒频移信号，确定第一射频单元的服务范围存在移动物体；或者，如果不存在由移动物体引起的多普勒频移信号，确定第一射频单元的服务范围不存在移动物体。关于具体的过程，可参见图9中的说明。
接入网设备中包括至少一个射频单元。前已述，该射频单元为接入网设备中实现射频功能的单元。在不同的接入网设备结构中，实现射频功能的单元有不同的名称。在本公开中，为了便于描述，将该实现射频功能的单元称为射频单元。以示意性的说明，确定第一接入检测信号的方式：
方式1：第一接收检测信号是由第一射频单元发送，且由第二射频单元接收的。第一射频单元与第二射频单元不同，第一射频单元和第二射频单元工作在唤醒态。
例如，接入网设备中包括第一射频单元和第二射频单元。第一射频单元和第二射频单元可以看作一个组合。第一射频单元发送检测信号，第二射频单元接收检测信号，第二射频单元接收的检测信号称为第一接收检测信号。检测信号还可称感知信号，检测信号可以为ZC序列，或格雷序列等。
方式2：第一接收检测信号是由第二射频单元发送，且由第一射频单元接收的。第一射频单元与第二射频单元不同，且第一射频单元和第二射频单元工作在唤醒态。
与方式1相同，接入网设备中包括第一射频单元和第二射频单元，且该两个射频单元为不同的射频单元。第二射频单元发送检测信号，第一射频单元接收检测信号，第一射频单元接收的检测信号称为第一接收检测信号。
如图6a所示，以接入网设备的三层架构为例，接入网设备中包括BBU、RHUB、pRRU0、和pRRU1，在指定时隙，执行以下过程：
1、BBU通过RHUB向pRRU0发送检测信号。
2、pRRU0置于发射状态，发射检测信号。
3、pRRU1置于接收状态，接收检测信号，且将接收的检测信号转发给BBU。
4、BBU对接收的检测信号进行雷达处理；确定是否存在由移动物体引起的多普勒频移信号；如果存在频移信号，则确定存在移动物体；否则确定不存在移动物体。检测移动物体的范围，参见图6a。该检测移动物体的范围可称为pRRU0的服务范围和/或pRRU1的服务范围。
方式3：第一接收检测信号是由所述第一射频单元的第一天线发送，且由所述第一射频单元的第二天线接收的。
第一射频单元连接有第一天线和第二天线，第一天线发送检测信号，第二天线接收检测信号，第二天线接收的检测信号称为第一接收检测信号。第一射频单元工作在唤醒态。
如图6b所示，以接入网设备的三层架构为例，接入网设备中包括BBU、RHUB和pRRU0、在指定时隙，执行以下过程：
1、BBU通过PHUB向pRRU0发送检测信号。
2、pRRU0的天线0置于发射状态，发射检测信号。
3、pRRU0的天线1置于接收状态，接收检测信号，且将接收的检测信号转发给BBU。
4、BBU对接收的检测信号进行雷达处理，确定是否存在移动物体。在该过程中，检测移动物体的范围，可参见图6b所示。该检测移动物体的范围也称为pRRU0的服务范围。
可以理解的是，在上述方式1中，具体由第二射频单元连接的某个天线发送检测信号，第一射频单元连接的某个天线接收检测信号。在上述方式2中，具体由第一射频单元连接的某个天线发送检测信号，第二射频单元连接的某个天线接收检测信号。
步骤502：第一射频单元的服务范围存在移动物体，第一射频单元工作在唤醒态；或者，第一射频单元的服务范围不存在移动物体，且所述第一射频单元为非监测射频单元，第一射频单元工作在休眠态；或者，第一射频单元的服务范围不存在移动物体，且第一射频单元为监测射频单元，第一射频单元工作在唤醒态。
其中，所述监测射频单元在第一时间段的初始阶段工作在唤醒态，所述非监测射频单元在第一时间段的初始阶段工作在休眠态。可选的，休眠态也称为节能态，唤醒态也称为检测业务态，或者感知业务态。对监测射频单元和非监测射频单元作如下说明：
1、监测射频单元和非监测射频单元是固定不变的。
例如，在接入网设备出厂时，即由厂家配置完成：接入网设备中的哪些射频单元为监测射频单元，哪些射频单元为非监测射频单元。其中，监测射频单元始终工作在唤醒态，非监测射频单元在接入网设备开启或重启时工作在休眠态，后续按需唤醒非监测射频单元，工作在唤醒态。例如，在非监测射频单元的服务范围内检测到移动物体时，将非监测射频单元唤醒，非监测射频单元工作在唤醒态。一段时间后，如果非监测射频单元的服务范围内检测不到移动物体，可再关闭该唤醒的非监测射频单元，非监测射频单元再次切换到休眠态。也就是，在该设计中，监测射频单元始终工作在唤醒态。对于非监测射频单元在初始阶段工作在休眠态。后续可根据非监测射频单元的服务范围内是否检测到移动物体，对非监测射频单元的工作状态进行调整。
在该设计中，前述“第一时间段”可为指永久的时间。监测射频单元始终工作在唤醒态，非监测射频单元在工作的初始阶段工作在休眠态。
2、监测射频单元和非监测射频单元是可配置的。
接入网设备中的监测射频单元和非监测射频单元并不是固定的，可以配置接入网设备中的监测射频单元和非监测射频单元。例如，根据接入网设备的应用场景，或者需求等，对接入网设备中的监测射频单元和非监测射频单元进行配置。或者，可每间隔一段时间或称为周期性，配置接入网设备中的监测射频单元和非监测射频单元等。
在该设计中，监测射频单元和非监测射频单元，可以在接入网设备出厂时配置完成。在接入网设备的使用过程中，可改变出厂配置的监测射频单元和非监测射频单元。或者，接入网设备在出厂时，并未配置监测射频单元和非监测射频单元。用户自行配置接入网设备的监测射频单元和非监测射频单元等。
在该设计中，前述“第一时间段”可指两次配置监测射频单元和非监测射频单元的时间段。在每次配置时，将监测射频单元的工作状态设置为工作在唤醒态。将非监测射频单元的初始工作状态设置为休眠态。
可选的，在本公开中，可为接入网设备中的第一射频单元设置定时器，第一射频单元为监测射频单元或非监测射频单元。在第一射频单元的定时器的运行期间，第一射频单元工作在唤醒态。在第一射频单元的定时器过期后，如果第一射频单元为非监测射频单元，第一射频单元切换到休眠态。因此，在本公开中，当在第一射频单元的服务范围内检测到移动物体时，需要重启第一射频单元的定时器。在工作在唤醒态的第一射频单元的服务范围内没有检测到移动物体，将第一射频单元切换到休眠态时，具体为：在第一射频单元的定时器到期后，第一射频单元工作在休眠态。
可选的，在确定第一射频单元工作在唤醒态时，将第一射频单元的相邻射频单元也唤醒。如此操作的目的主要为：用户是移动的，在确定第一射频单元的服务范围内存在用户或移动物体时，用户很可能会移动到第一射频单元的相邻射频单元的服务范围内，因此将相邻射频单元也唤醒，从而提高用户的服务体验。例如，在一种实现方式中：当唤醒第一射频单元时，还需要唤醒第一射频单元的相邻射频单元中处于休眠态的射频单元；重启所唤醒的相邻射频单元的定时器；在所述相邻射频单元的定时器的运行期间，相邻射频单元工作在唤醒态。
在本公开中，利用图5的流程，确定第一射频单元的服务范围内是否存在移动物体，并根据第一射频单元的服务范围内是否存在移动物体，执行相应的节能策略。或者，可以先确定第一射频单元的服务范围内是否存在连接态终端设备。如果第一射频单元的服务范围内不存在连接态终端设备，再则执行图5的流程。即前述图5中的流程中，所述第一射频单元的服务范围不存在连接态终端设备。关于确定第一射频单元的服务范围内是否存在连接态终端设备的方式，不作限制。例如，确定第一射频单元检测到的RSRP是否大于或等于(或大于)第一门限。如果大于或等于(或者，大于)第一门限，则确定第一射频单元的服务范围内存在连接态终端设备；如果小于(或者，小于或等于)第一门限，则确定第一射频单元的服务范围内不存在连接态终端设备。
例如，接入网设备中包括N个射频单元，N个射频单元的编号依次为0至N-1，N个射频单元中存在监测射频单元和非监测射频单元。监测射频单元工作在唤醒态，非监测射频单元在初始阶段工作在休眠态。监测射频单元可认为是“哨兵”，非监测射频单元根据其服务范围内是否有移动物体进入，按需唤醒，实现接入网设备的节能。对于唤醒的射频单元，射频单元可以为监测射频单元或非监测射频单元。可以为监测射频单元和非监测射频单元均设置定时器，下文以该示例进行描述。或者，可以为非监测射频单元设置定时器，可以不为监测射频单元设置定时器，监测射频单元工作在唤醒态。在唤醒射频单元时，重启该射频单元的定时器，在定时器的运行期间，对应的射频单元工作在唤醒态。在定时器过期后，对应的射频单元切换到休眠态。
下面结合附图，对上述场景中的节能方法进行说明，如图7所示，至少包括：
步骤701：启动/重启N个射频单元的定时器，N个射频单元的编号为0至N-1。
步骤701是可选的。例如，可以在接入网设备开机或重启的阶段，执行步骤701。在本公开中，周期性对N个射频单元进行节能操作。例如，在第一时间，执行下述步骤702至步骤715，按需对N个射频单元中的非监测射频单元进行节能操作。休眠一段时间后，在第二时间，再次执行下述步骤702至步骤715，按需对N个射频单元中的非监测射频单元进行节能操作。
步骤702：获取N个射频单元的工作状态、连接态终端设备的检测结果、移动物体的检测结果，将 i的取值设置为0。
射频单元的工作状态具体指射频单元工作在唤醒态或休眠态。连接态终端设备的检测结果是指在射频单元的服务范围内是否检测到连接态终端设备。移动物体的检测结果是指在射频单元的服务范围内是否检测到移动物体。
步骤703：判断i的取值是否小于N；如果小于N，执行步骤704；否则执行步骤705，休眠一定时间，再次执行步骤702；
步骤704：判断射频单元i是否工作在唤醒态；如果射频单元i工作在唤醒态，则执行步骤707；否则执行步骤706；
步骤706：设置i＝i+1；
步骤707：判断射频单元i的服务范围内是否检测到连接态终端设备；如果检测到连接态终端设备，执行步骤708；否则，执行步骤712。
步骤707是可选的。例如，在图7的流程中可以不执行步骤707。例如，在步骤704中，如果确定射频单元i工作在唤醒态，直接执行步骤712，判断射频单元i的服务范围内是否检测到移动物体。因为当移动物体为用户时，用户的终端设备的状态可以为连接态、空闲态或非激活态。也就是说，采用步骤712可确定射频单元i的服务范围内是否存在终端设备，即可确定射频单元i的服务范围内是否存在连接态终端设备，因此可以不再执行步骤707。或者，在图7的流程中，可以执行步骤707。例如，在步骤704中，如果确定射频单元i工作在唤醒态，则执行步骤707，判断射频单元i的服务范围内是否存在连接态终端；如果检测不到连接态终端，再执行步骤712，判断射频单元i的服务范围内是否检测到移动物体。
步骤708：重启射频单元i的定时器；
步骤709：确定射频单元i的相邻射频单元是否工作在唤醒态；如果工作在唤醒态，则执行步骤710：重启相邻射频单元的定时器；如果工作在休眠态，则执行步骤711：唤醒相邻射频单元，且重启相邻射频单元的定时器。
步骤712：判断射频单元i的服务范围内是否检测到移动物体；如果检测到移动物体，则执行步骤708；如果没有检测到移动物体，则执行步骤713；
步骤713：判断射频单元i是否为监测射频单元；如果是监测射频单元，则执行步骤706；如果不是监测射频单元，则执行步骤714；
步骤714：判断射频单元i的定时器是否到期；如果到期，则执行步骤715；如果未到期，则执行步骤706，继续对射频单元i+1执行节能操作；
步骤715：射频单元i的工作状态切换到休眠态，射频单元i工作在休眠态。
在本公开中，根据射频单元的检测结果，对非监测射频单元按需唤醒。例如，当非监测射频单元内存在连接态终端设备或存在移动物体时，才唤醒非监测射频单元；否则非监测射频单元工作在休眠态，实现接入网设备的节能。
如图8所示，接入网设备中包括9个射频单元。9个射频单元中包括2个监测射频单元和7个非监测射频单元。2个监测射频单元工作在唤醒态，7个非监测射频单元在初始阶段工作在休眠态。按需对7个非监测射频单元进行唤醒。2个监测射频单元和7个非监测射频单元的分布参见图8。
在初始阶段，参见图8中的第一个示意图，2个监测射频单元工作在唤醒态。在2个监测射频单元中的至少一个监测射频单元的服务范围内检测到移动物体时，则唤醒监测射频单元的相邻非监测射频单元。
在图8的第二个示意图中，是以左上角的监测射频单元检测到移动物体，唤醒左上角的监测射频单元的相邻射频单元为例的。
由于在射频单元工作在唤醒态时，射频单元的指示灯是点亮的。在射频单元工作在休眠态时，射频单元的指示灯是熄灭的。因此，在本公开中，当用户移动到某个射频单元的服务范围内或某个射频单元的附近时，该射频单元的指示灯是点亮的。同时，射频单元在唤醒时，设置有定时器，当定时器过期后，射频单元将再次切换到休眠态。也就是当用户移出射频单元的服务范围或射频单元的附近时，该射频单元的指示灯在点亮一段时间后，将再次熄灭。因此，在本公开中，对于非监测射频单元，可实现随用户的进入，则指示灯点亮，工作在唤醒态。当用户离开后，非监测射频单元切换到休眠态，指示灯熄灭， 实现“灯随人亮，人走灯熄”。
在图8的第三个示意图中，在第二个示意图中唤醒的非监测射频单元，随着用户的离开和定时器的过期等，将切换到休眠态，在第二个示意图中唤醒的非监测射频单元的指示灯熄灭。同时，随着用户移动，用户移动到右下角的监测射频单元，监测射频单元监测到其服务范围内存在移动物体，则唤醒右下角监测射频单元的相邻射频单元。当用户离开接入网络的服务范围内，接入网设备的射频单元的工作状态，再切换到图8中的第一个示意图。
在本公开中，无需购买专用硬件，无需改变接入网设备的硬件，不影响接入网设备的通信，实现接入网设备节能。同时，接入网设备中的非监测射频单元按需唤醒，自适能节能，对接入网设备实现最大程度的节能。
本公开中，在无线通信系统中引入雷达检测，利用该雷达检测实现无线通系统中物体(例如终端设备)的定位等。以接入网设备利用雷达检测，检测移动物体为例。本公开提供一种检测移动物体的方法，如图9所示，该方法包括：
接入网设备中包括基带单元，以基带单元实现移动物理检测为例。可以理解的是，接入网设备中很多单元，均可实现移动物理检测。下文仅为示例性描述，并不作为对本公开的限制。
步骤901：基带单元根据第一接收检测信号，确定第一射频单元的服务范围是否存在移动物体。
基带单元确定第一接收检测信号的过程，参见图5。例如，所述第一接收检测信号是由所述第一射频单元发送，且由第二射频单元接收的；或者，所述第一接收检测信号是由第二射频单元发送，且由所述第一射频单元接收的；或者，所述第一接收检测信号是由所述第一射频单元的第一天线发送，且由所述第一射频单元的第二天线接收的。
步骤901的实现过程可包括：根据所述第一接收检测信号，确定是否存在由移动物体引起的多普勒频移信号；如果存在由移动物体引起的多普勒频移信号，确定第一射频单元的服务范围内存在移动物体；或者，如果不存在由移动物体引起的多普勒频移信号，确定第一射频单元的服务范围不存在移动物体。
步骤901的处理过程可称为雷达处理。对雷达处理的实现方式，不作限制。以下示例性的说明，参见图10，雷达处理的过程：
1、多帧累积信道估计。例如，对第一接收检测信号进行信道估计，得到一个向量。每个接收检测信号在对应的帧中发送，多帧累计过程是将多帧得到的信道估计结果按照时间顺序排序，将多帧的信道估计结果组合成一个矩阵。
2、相位补偿。相位补偿的过程即补偿相位噪声，补齐不同帧信道估计结果的初相。
3、静态杂波消除。静态杂波消除的过程中，利用滤波器滤除杂波。
4、多普勒计算。多普勒计算的过程可使用离散傅里叶变换计算得到距离多普勒谱；
5、恒虚警率(constant false-alarm rate，CFAR)检测移动目标。CFAR检测算法在距离多普勒上搜索目标信号，该目标信号可为多普勒频移信号。如果搜索到多普勒频移信号，则检测结果为存在由移动物体引起的多普勒频移信号；或者，如果未搜索到多普勒频移信号，则检测结果为不存在由移动物体引起的多普勒频移信号。
6、上报检测结果。将检测结果上报给对应的单元。该上报检测结果的步骤是可选的，可以执行。例如，其它单元需要根据该检测结果，执行相应的操作，则可以将该检测结果，上报给对应的单元。或者，上述上报检测结果的步骤可以不执行。例如，由基带单元执行前述步骤1至5，获得检测结果。后续基带单元直接利用该检测结果，对射频单元执行节能操作。基站单元直接利用该检测结果，无需再向其它单元上报，上述上报检测结果的步骤不再执行。
步骤902：基带单元根据第一射频单元的服务范围内是否存在移动物体，对第一射频单元执行节能操作。
执行节能操作的过程，参见图5中的说明。例如，第一射频单元为非监测射频单元，在第一射频单元的服务范围内不存在移动物体时，则第一射频单元工作在休眠态。
步骤902是可选的，可以执行，或不执行，不作限制。例如，本公开的目的为：检测射频单元的服务范围内是否存在移动物体，则无需再执行任何步骤，可以不再执行步骤902。或者，根据射频单元的服务范围内是否存在移动物体，执行节能操作，则执行步骤902。或者，根据射频单元的服务范围内是否存在移动物理，可执行其它操作，则不执行步骤902。
通过上述设计，可实现射频单元的服务范围内是否有移动物体的检测，进一步对连接态、空闲态或 非激活态终端都能实现有效检测。
可以理解的是，为了实现上述方法中的功能，基带单元包括了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员很容易意识到，结合本公开所描述的各个示例的单元以及方法步骤，本公开能够以硬件或硬件和计算机软件相结合的形式来实现。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场景和设计约束条件。
