Description

一种通信方法、装置及系统 技术领域
本申请涉及通信领域，并且更具体地，涉及一种通信方法、装置及系统。
背景技术
随着科技的发展，物联网(Internet of things，IoT)设备逐渐的进入了人们的生活，并在逐渐地改善着人们的生活。
为了降低IoT设备的功耗，根据IEEE 802.11的省电模式操作，设备可以进入休眠状态。处于休眠状态中的设备可以享受更低的功耗，但会增加接收数据的时延。因此，处于休眠状态中的设备需要周期性的接收来自网络设备的唤醒信号，根据唤醒信号中携带的信息判断是否有来自网络设备的下行数据需要接收。
为了能够进一步降低IoT设备的功耗，IEEE 802.11ba为IoT设备设计配备了两个无线电链，称为主连接无线电(primary connection radio,PCR)和伴连接无线电(companion radio,CR)，主连接无线电也可以称为主接收机，伴连接无线电也可以称为唤醒接收机。当设备通过唤醒接收机检测到唤醒信号后，可以根据该唤醒信号触发主接收机的唤醒，进而，主接收机可用于数据传输。唤醒接收机的功耗更低，且唤醒接收机复用主接收机的全部或部分射频硬件，可以降低成本。但是，唤醒接收机支持的接收天线数会影响唤醒接收机的接收性能和覆盖能力。主接收机和唤醒接收机在接收性能和覆盖能力上存在差异，会影响网络设备调度传输时采用的传输参数，降低系统的传输效率，同时也会造成覆盖空洞的问题，影响通信质量。
发明内容
本申请提供一种通信方法、装置及系统，能够提高传输效率，同时解决覆盖空洞的问题，提高通信质量。
第一方面，提供了一种通信方法，该方法由终端设备执行，或者也可以由配置于终端设备的部件(如电路或芯片)执行。本申请对此不作限定。
该方法包括：终端设备向网络设备发送第一指示信息，所述第一指示信息用于指示所述终端设备的第一接收机的接收天线数量信息；所述终端设备使用所述第一接收机接收所述网络设备发送的唤醒信号。
基于上述技术方案，终端设备可以通过第一指示信息向网络设备上报终端设备的第一接收机支持的接收天线数量信息，从而辅助网络设备确定唤醒信号的传输参数，提高传输效率。此外，上述技术方案提高了终端设备实现的灵活性，使得终端设备可以根据自身的节能需求或覆盖需求选择第一接收机支持的接收天线数量信息进行上报。
例如，智能家电根据自身的节能需求发送第一指示信息，向基站上报唤醒接收机支持的接收天线数。基站接收第一指示信息，并通过第一指示信息确定智能家电唤醒接收机支持的接收天线数，从而调整唤醒信号的传输参数，提高了传输效率。
在一种可能的设计中，所述第一指示信息指示所述第一接收机支持的接收天线数。
在一种可能的设计中，所述第一指示信息指示所述第一接收机和第二接收机的接收天线数相同。
采用该设计，可以节省第一指示信息的信令开销。终端设备通过第一指示信息指示第一接收机和第二接收机支持的接收天线数相同，就不需要再额外指示该第一接收机具体的接收天线数，从而节省了信令开销。
在一种可能的设计中，所述第一指示信息指示所述第一接收机和所述第二接收机的接收天线数不同。
在一种可能的设计中，所述终端设备向所述网络设备发送第二指示信息，所述第二指示信息指示所述第一接收机支持的接收天线数。
在一种可能的设计中，所述第一指示信息指示所述第一接收机支持的接收天线数为1、2或4中的一个。
在一种可能的设计中，所述第一指示信息指示所述第一接收机支持的频带信息，其中，所述第一接收机支持的接收天线数和所述第一接收机支持的频带信息存在关联关系。
采用该设计，可以节省信令开销。终端设备通过第一指示信息指示第一接收机支持的频带信息。基站接收第一指示信息，并通过第一接收机支持的接收天线数和第一接收机支持的频带信息的关联关系确定接收天线数，就不需要再额外接收指示该第一接收机具体接收天线数的指示信息，从而节省了信令开销。
在一种可能的设计中，所述第一指示信息指示所述第二接收机支持的接收天线数；所述第一接收机支持的接收天线数和所述第二接收机支持的接收天线数相同。
采用该设计，可以节省信令开销。终端设备通过第一指示信息指示第二接收机支持的接收天线数。基站接收第一指示信息，并通过第一接收机支持的接收天线数和第二接收机支持的接收天线数相同确定第一接收机支持的接收天线数，就不需要再额外接收一个指示信息指示该第一接收机的接收天线数，从而节省了信令开销。
在一种可能的设计中，包括：所述终端设备接收配置信息；处于第一状态的所述终端设备根据所述配置信息进入第二状态。
采用该设计，终端设备可以根据配置信息改变所处状态。考虑到第一接收机支持不同于第二接收机支持的接收天线数，第一接收机和第二接收机的覆盖能力是不同的，接收天线数越多，覆盖范围越大。根据配置信息，终端设备可以改变所处的状态，采用不同的接收机与网络设备进行通信，避免第一接收机和第二接收机的覆盖能力差距产生的覆盖空洞，从而提高通信质量。
例如，行人身上携带智能穿戴设备。行人移动至距离基站较近的位置，智能穿戴设备处于第一状态，采用唤醒接收机接收基站发送的唤醒信号。行人移动至距离基站较远的位置，智能穿戴设备的唤醒接收机支持的接收天线数不能满足行人和基站之间的覆盖距离，智能穿戴设备根据配置信息进入第二状态，采用主接收机与基站进行通信。因此，采用该设计可以避免第一接收机和第二接收机的覆盖能力差距产生的覆盖空洞，从而提高通信质量。
在一种可能的设计中，所述配置信息为第一阈值。
在一种可能的设计中，包括：所述配置信息为多个候选阈值，其中，不同的候选阈值与所述第一接收机可能支持的不同的接收天线数存在关联关系；所述终端设备根据所述第 一接收机支持的接收天线数从所述多个候选阈值中确定所述第一阈值。
采用该设计，终端设备可以根据第一接收机可能支持的不同的接收天线数更加准确的判断从第一状态进入第二状态的时机，进一步提高通信质量。
在一种可能的设计中，包括：所述配置信息为一个候选阈值以及一个或多个偏置信息；所述候选阈值与所述第一接收机可能支持的一个接收天线数存在关联关系；所述不同的偏置信息与所述第一接收机可能支持的不同的接收天线数存在关联关系；所述终端设备根据所述第一接收机支持的接收天线数从所述一个或多个偏置信息中确定第一偏置信息；所述终端设备结合所述候选阈值和所述第一偏置信息确定所述第一阈值。
采用该设计，可以节省信令开销。网络设备配置偏置信息所需的信令开销通常小于配置候选阈值本身所需的信令开销。终端设备结合一个候选阈值和一个偏置信息确定第一阈值，可以使网络设备采用更小的信令开销达到同样的配置效果。
在一种可能的设计中，包括：所述第二接收机或所述第一接收机基于第一参考信号进行测量，并获得测量结果；所述测量结果与所述第一阈值满足第一关系；所述终端设备从所述第一状态进入所述第二状态。

采用该设计，可以节省信令开销。基站接收第一指示信息，并通过第一接收机支持的接收天线数和第二接收机支持的接收天线数相同确定第一接收机支持的接收天线数，就不需要再额外接收一个指示信息指示该第一接收机的接收天线数，从而节省了信令开销。
在一种可能的设计中，包括：所述网络设备向所述终端设备发送配置信息；所述配置信息用于所述终端设备进入第一状态或第二状态。
采用该设计，终端设备可以根据配置信息改变所处状态。考虑到第一接收机支持不同于第二接收机支持的接收天线数，第一接收机和第二接收机的覆盖能力是不同的，接收天线数越多，覆盖范围越大。根据配置信息，终端设备可以采用不同的接收机与网络设备进行通信，避免第一接收机和第二接收机的覆盖能力差距产生的覆盖空洞，从而提高通信质量。
例如，行人身上携带智能穿戴设备。行人移动至距离基站较近的位置，智能穿戴设备处于第一状态，采用唤醒接收机接收基站发送的唤醒信号。行人移动至距离基站较远的位置，智能穿戴设备的唤醒接收机支持的接收天线数不能满足行人和基站之间的覆盖距离，智能穿戴设备根据配置信息进入第二状态，采用主接收机与基站进行通信。因此，采用该设计可以避免第一接收机和第二接收机的覆盖能力差距产生的覆盖空洞，从而提高通信质量。
在一种可能的设计中，所述配置信息为第一阈值。
在一种可能的设计中，所述配置信息为多个候选阈值，其中，不同的候选阈值与所述第一接收机可能支持的不同的接收天线数存在关联关系。
采用该设计，终端设备可以根据第一接收机可能支持的不同的接收天线数更加准确的判断从第一状态进入第二状态的时机，进一步提高通信质量。
在一种可能的设计中，包括：所述配置信息为一个候选阈值以及一个或多个偏置信息；所述候选阈值与所述第一接收机可能支持的一个接收天线数存在关联关系；所述不同的偏置信息与所述第一接收机可能支持的不同的接收天线数存在关联关系。
采用该设计，可以节省信令开销。网络设备配置偏置信息所需的信令开销通常小于配置候选阈值本身所需的信令开销。终端设备结合一个候选阈值和一个偏置信息确定第一阈值，可以使网络设备采用更小的信令开销达到同样的配置效果。
第三方面，提供了一种终端设备，此终端设备可以执行第一方面提供的方法，终端设备具体包括：处理单元，用于确定第一指示信息，所述第一指示信息用于指示所述终端设备的第一接收机的接收天线数量信息；收发单元，用于向网络设备发送第一指示信息；所述收发单元还用于，使用所述第一接收机接收所述网络设备发送的唤醒信号。

以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)终端设备
在本申请实施例中，终端设备包括向用户提供语音和/或数据连通性的设备，具体的，包括向用户提供语音的设备，或包括向用户提供数据连通性的设备，或包括向用户提供语音和数据连通性的设备。终端设备也可以称为用户设备(user equipment,UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端(terminal)、无线通信设备、用户代理或用户装置。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端设备、增强现实(augmented reality,AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart  grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、蜂窝电话、无绳电话、会话启动协议(session initiation protocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network,PLMN)中的终端设备等。
其中，可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
此外，终端设备还可以是IoT系统中的终端设备。IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。
本申请实施例中，用于实现终端设备的功能的装置可以是终端设备，也可以是能够支持终端设备实现该功能的装置，例如芯片系统或芯片，该装置可以被安装在终端设备中。本申请实施例中，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。
本申请对于终端设备的具体形式不作限定。
2)网络设备
本申请实施例中，网络设备可以是任意一种具有无线收发功能的设备。该设备包括但不限于：演进型节点B(evolved Node B,eNB)、无线网络控制器(radio network controller,RNC)、节点B(Node B,NB)、基站控制器(base station controller,BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如，home evolved NodeB，或home NodeB，HNB)、基带单元(base band unit,BBU)，无线保真(wireless fidelity,WIFI)系统中的接入点(access point,AP)、无线中继节点、无线回传节点、传输点(transmission point,TP)或者发送接收点(transmission and reception point,TRP)等，还可以为5G NR系统中的下一代节点B(next generation node B,gNB)或传输点(TRP或TP)，或者，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit,DU)等。或者该网络设备可以为未来第六代移动通信技术(the 6th generation,6G)网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。本申请实施例对网络设备所采用的具体技术和具体设备形态不做限制。
在一些部署中，gNB可以包括集中式单元(centralized unit,CU)和DU。gNB还可以包括有源天线单元(active antenna unit,AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control,RRC)，分组数据汇聚层协议(packet data convergence protocol,PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control,RLC)层、介质接入控制(medium access control,MAC)层和物理(physical,PHY)层的功能。AAU实现部分物理层处 理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network,RAN)中的网络设备，也可以将CU划分为核心网(core network,CN)中的网络设备，本申请对此不做限定。
网络设备为小区提供服务，终端设备通过网络设备分配的传输资源(例如，频域资源，或者说，频谱资源)与小区进行通信，该小区可以属于宏基站(例如，宏eNB或宏gNB等)，也可以属于小小区(small cell)对应的基站，这里的小小区可以包括：城市小区(metro cell)、微小区(micro cell)、微微小区(pico cell)、毫微微小区(femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
3)主接收机(main radio)
一般情况下，无论终端设备在空闲态或者非活动态执行接收寻呼的流程时，还是终端设备在连接态进行数据接收时，都是通过相同的接收模块(或者接收机，或者接收电路)来实现。在本申请中，为便于描述，将完成这些功能(或执行相关步骤)的模块称为主接收机。可以理解，主接收机仅是为区分做的命名，其具体命名不对本申请的保护范围造成限定。
主接收机的功耗较高，但主接收机的功能更多，可以收发的信号种类也更多。在与网络设备通信过程中，主接收机用于承担主要的数据传输。
在本申请中，主接收机例如可用于接收同步信号块(synchronization signal block，SSB)、物理下行控制信道(physical downlink control channel,PDCCH)、物理下行共享信道(physical downlink shared channel,PDSCH)、或信道状态信息参考信号(channel state reference signal，CSI RS)，或者可用于接收二进制相移键控(binary phase shift keying，BPSK)、正交相移键控(quadrature phase shift keying，QPSK)、16正交振幅调制(quadrature amplitude modulation，QAM)、64QAM或256QAM调制信号，或者可用于接收做快速傅里叶变换(fast Fourier transform，FFT)的信号或快速傅里叶逆变换(inverse fast fourier transform，IFFT)的信号。主接收机可以是本地振荡器精度较高的接收机。
终端设备使用主接收机接收的信号可以被称为在主链路上传输的信号，其中，主链路表征了终端设备和网络设备间的一种连接关系，是一个逻辑概念，而非一个物理实体。可以理解，主链路仅是为区分做的命名，其具体命名不对本申请的保护范围造成限定。
当终端设备采用主接收机接收寻呼时，功耗较高。例如，终端设备需要每隔一个非连续接收(discontinuous reception，DRX)周期就周期性地唤醒一次主接收机，当终端设备没有信令和数据业务进行传输时，在每个DRX周期唤醒一次主接收机的行为造成了终端设备的主要功耗。此外，由于主接收机较为复杂，其运行时的基准功耗(或静态功耗)比较高。
为了降低终端设备接收寻呼带来的功耗，一种可能的方法是，终端设备可以使用一个单独的低功耗小电路接收唤醒信号。该低功耗小电路有能力超低功耗监听唤醒信号，且主接收机可以处于关闭或深度睡眠状态，而该低功耗小电路可以处于激活状态或间歇性激活状态。当终端设备通过该低功耗小电路检测到唤醒信号后，终端设备可根据该唤醒信号触发主接收机的唤醒。主接收机打开时，可用于数据传输。该低功耗小电路可以使用一个结 构简单的单独的小电路、模块或芯片实现，其功耗较低。
4)唤醒接收机(wake-up receiver，WUR)
上述低功耗小电路可以称为例如唤醒接收机(wake up receiver，WUR)、低功耗唤醒接收机(low power wake-up receiver)、唤醒射频(wake-up radio，WUR)、辅接收机，或者也可以称为唤醒电路、低功耗电路，等等，关于其命名，本申请不予限制。下文为便于说明，统一描述为唤醒接收机。
在本申请中，唤醒接收机例如可用于接收用开关键控(on-off key，OOK)调制或频移键控(frequency shift keying，FSK)调制的信号，或者可用于接收在生成或解码过程中不用做FFT或IFFT的信号，或者可用于接收曼彻斯特编码的信号。
终端设备使用唤醒接收机接收的信号可以被称为在唤醒链路上传输的信号，其中，唤醒链路表征了终端设备和网络设备间的一种连接关系，是一个逻辑概念，而非一个物理实体。可以理解，唤醒链路仅是为区分做的命名，其具体命名不对本申请的保护范围造成限定，例如，唤醒链路还可以称为WUR链路。
在本申请中，唤醒接收机和主接收机相比能耗更低，示例性地，可表现为以下方面中的至少一种：唤醒接收机接收唤醒链路上传输的信号的能耗与主接收机接收主链路上传输的信号的能耗相比能耗更低；与主接收机相比，唤醒接收机本身的能耗更低；唤醒接收机是本地振荡器精度较低的接收机；唤醒接收机是采用包络检波的接收机；唤醒接收机是不需要做FFT或IFFT的信号的接收机。唤醒接收机节能的关键在于不采用高精度晶振(0.1ppm)，或者采用低精度的振荡器(如环形振荡器)的接收机结构。采用这种接收机架构，最终都需要采用包络检波的方式实现下变频。包络检波是一种非相干接收方式，相比主接收机相干接收的方式，覆盖性能存在较大差距。
图2示出了本申请的终端设备的接收机的一例示意图。其中，唤醒接收机可用于接收唤醒信号，进而，唤醒接收机可根据该唤醒信号中是否包含该终端设备的标识，判断是否触发主接收机的唤醒。作为示例，若唤醒信号中包含该终端设备的标识，则触发主接收机唤醒(开启)，如图2中的(a)所示；若唤醒信号中不包含该终端设备的标识，则主接收机处于关闭状态或者深度睡眠状态，如图2中的(b)所示。
唤醒接收机复用主接收机的部分射频硬件，比如主接收机的接收天线，可以降低成本。
5)唤醒信号
使用唤醒接收机接收的信号可以称作“唤醒信号”、“在唤醒链路上传输的信号”、“WUR信号”，等等，关于其命名，本申请不予限制。下文为便于说明，统一描述为唤醒信号。
唤醒信号可用于指示一个终端设备或者一组终端设备是否被寻呼。示例性地，若唤醒信号中包括某个终端设备的标识(UE ID)，则表示该终端设备被寻呼；相反地，若唤醒信号中不包括该终端设备的标识，则表示该终端设备未被寻呼。其中，UE ID例如为5G-S-TMSI，或者，UE ID可由5G-S-TMSI中的部分比特位组成，例如，UE ID可由5G-TMSI中的高比特位组成。
终端设备在收到唤醒信号后有两种可能的工作方式，在第一种方式中，终端设备在收到唤醒信号后，可根据该唤醒信号唤醒主接收机，并通过主接收机接收寻呼(paging)，之后，再发起随机接入；在第二种方式中，终端设备在收到唤醒信号后，可根据该唤醒信号唤醒主接收机并直接发起随机接入。
在本申请中，唤醒信号可以是用开关键控(on-off key，OOK)调制或频移键控 (frequency shift keying，FSK)调制的信号，或者也可以是在生成或解码过程中不用快速傅里叶变换(fast Fourier transform，FFT)或快速傅里叶逆变换(inverse fast fourier transform，IFFT)的信号，或者也可以是采用曼彻斯特编码的信号。当采用OOK调制时，每个比特(该比特可以是编码后的比特)对应一个符号(也可以被称为一个码片(chip))。在一种可能的情况中，当比特为1时，表示该符号长度内有信号发出(即该符号长度内信号功率不为0)，而当比特为0时，表示该符号长度内无信号发出(即该符号长度内信号功率为0)；在另一种情况中，当比特为0时，表示该符号长度内有信号发出(即该符号长度内信号功率不为0)，当比特为1时，表示该符号长度内无信号发出(即该符号长度内信号功率为0)。
网络设备通过唤醒链路传输的信号，除了唤醒信号外，可能还包含同步信号。同步信号可用于唤醒链路的时间同步，还可用于终端设备检测唤醒链路的质量。
6)接收天线数
接收天线数也可以表述为“接收分支(Rx branch)数”、“多输入多输出层(MIMO layer)数”，等等，关于其命名，本申请不予限制。下文为便于说明，统一描述为接收天线数。
上面对本申请中涉及到的术语做了简单说明，下文实施例中不再赘述。
如前所述，唤醒接收机的功耗更低，且唤醒接收机复用主接收机的全部或部分射频硬件，可以降低成本。但是，唤醒接收机相比主接收机相干接收的方式，覆盖性能存在较大差距。同时，唤醒接收机支持的接收天线数也会影响唤醒接收机的接收性能和覆盖能力。图3示出了唤醒接收机支持不同的接收天线数示意图，接收天线数少，节能增益大，适用于功耗需求大的场景；接收天线数多，能够对抗深衰落，获取空域接收分集增益，在保证一定节能效果情况下，适用于覆盖需求大的场景。主接收机和唤醒接收机在接收性能和覆盖能力上存在差异，会影响网络设备调度传输时采用的传输参数，降低系统的传输效率，同时，开启唤醒接收机的终端设备在多个小区之间移动时可能会出现唤醒接收机的覆盖空洞。
有鉴于此，本申请提供一种通信方法和装置，能够提高传输效率，同时解决覆盖空洞的问题。下文将结合附图详细说明本申请实施例提供的通信方法。本申请实施例提供的通信方法可以应用于上述图1所示的通信系统中。
图4是本申请实施例提供的通信方法的一例示意图。该方法400可以包括S410至S440。应理解，图4示出了该通信方法的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其他操作或者图4中的各个操作的变形，或者是合理的步骤间的调换。
S410，终端设备发送第一指示信息，第一指示信息指示第一接收机支持的接收天线数量信息。
具体的，该第一接收机可以是终端设备的唤醒接收机，也可以是终端设备的主接收机。
在一种可能的设计中，终端可以根据自身覆盖需求、能耗需求、移动性需求中的一个或多个，在主接收机支持的接收天线数内，选择唤醒接收机支持的接收天线数，通过第一指示信息发送给网络设备。具体的，覆盖需求可以是根据业务情况或者是覆盖相关参数确定的。
示例性的，终端设备通过测量判断参考信号接收功率(reference signal received power,RSRP)较好，满足测量放松条件，终端设备可以上报唤醒接收机支持的接收天线数为1； 终端设备通过测量判断RSRP较差，或者，不满足测量放松条件，终端设备可以上报唤醒接收机支持的接收天线数为2或4。
根据上面示例，若第一接收机是终端设备的主接收机，相应的，第一指示信息指示第一接收机支持的接收天线数量信息可以是指示终端的主接收机支持的接收天线数。第一指示信息还可以进一步同时指示终端的唤醒接收机支持的接收天线数。
同样的，若第一接收机是终端设备的唤醒接收机，相应的，第一指示信息指示第一接收机支持的接收天线数量信息可以是指示终端的唤醒接收机支持的接收天线数。
可选的，第一指示信息指示第一接收机支持的接收天线数。这里的天线数可以是指具体的接收天线数量。
示例性的，终端设备确定的第一接收机支持的接收天线数为4，则第一指示信息指示4；终端设备确定的第一接收机支持的接收天线数为2，则第一指示信息指示2。示例性的，可以通过2比特信息指示具体的接收天线数量，例如00可以表示第一接收机支持的接收天线数为1，01可以表示第一接收机支持的接收天线数为2，10可以表示第一接收机支持的接收天线数为4。
除上述示例中的指示方式外，还可以其它方式指示第一接收机支持的接收天线数量。下面，将介绍两种情况，可以通过指示两个接收机接收天线数量的关系的方式指示第一接收机的天线数量。
情况一：第一指示信息指示第一接收机和第二接收机的接收天线数相同。
结合上述示例，具体介绍第一指示信息指示第一接收机和第二接收机的接收天线数相同的指示方式。例如，该第一接收机是终端设备的唤醒接收机，第二接收机是终端设备的主接收机。在这种情况下，终端设备在执行步骤410前可以预先通知第二接收机的接收天线数量，步骤410直接通过第一指示信息指示第一接收机和第二接收机的接收天线数相同，基站即根据预先获知的第二接收机的接收天线数量和第一指示信息，确定出第一接收机的接收天线数量。应理解，该预先通知也可以是在步骤410之后的。此外，基站也可以通过其它方式获知第二接收机的接收天线数量，在这种情况下，终端设备就可以不通知基站第二接收机的接收天线数量，从而进一步节省信令开销。通知第二接收机接收天线数量的方式可以参考上述实施例，在此不再赘述。
情况二：第一指示信息指示第一接收机和第二接收机的接收天线数不同。
在这种情况下，一种可能的实现方式是，终端设备向网络设备发送第二指示信息，第二指示信息指示第一接收机支持的接收天线数。步骤410通过第一指示信息指示第一接收机和第二接收机的接收天线数不同，基站即根据第一指示信息和第二指示信息，确定出第一接收机的接收天线数量。应理解，终端设备向网络设备发送第二指示信息也可以是在发送第一指示信息之前。具体的，该第二指示信息指示的接收天线数的确定方式可以参考指示第一接收机的接收天线数量的相关实施例，在此不再赘述。
另一种可能的实现方式是，步骤410通过第一指示信息指示第一接收机和第二接收机的接收天线数不同，基站可以根据第一指示信息和预设规则，确定出第一接收机的接收天线数。
