Description

信号接收方法及信号接收装置 技术领域
本申请实施例涉及通信技术领域，尤其涉及一种信号接收方法及信号接收装置。
背景技术
目前移动通信技术除了使用传统的低频(<3gHz)传输外，还在研究高频(高于6gHz)传输的可行性。相对于低频传输，高频有较多可用的且连续的无线频谱资源(尤其是在毫米波频段)，可支持提供更宽的物理信道。但是高频信号自由空间损耗大，受遮挡影响比较严重，穿透能力也要比低频信号差。因此当前主要引入波束赋形技术来应对这些挑战。
波束赋形利用了波形的干涉原理，信号经过加权后，形成窄带波束。其中，不同天线的波峰与波峰相遇位置叠加增强，波峰与波谷相遇位置叠加减弱。在多个天线的共同波峰叠加方向，从而使得信号强度得到显著增强。
然而，由于天线阵列的天线规模的增大，天线和射频前端器件的功耗占终端设备功耗的比重不断的增加，尤其是终端设备作为接收端时，射频前端器件的功耗大小与天线的数量有直接关系。
因此，本申请具体研究了在终端设备作为接收端时，如何降低射频前端器件的功耗。

具体实施方式
下面将结合本申请实施例中的附图对本申请实施例中技术方案进行描述。
波束赋形是一种基于天线阵列的信号预处理技术，通过调整天线阵列中每个阵元的加权系数产生具有指向性的波束，从而获得明显的信号增益，又可以称为波束增益或阵列增益。如图1所示，图1利用了波束赋形的原理，通过调整终端设备中各天线(antenna，简称A)的相位，使得终端设备发射(transmit，TX)的信号经过加权后能量叠加，形成指向接收端的窄带波束。其中，φ表示移相器，通过控制(control，简称C)可改变移相器的相位大小，从而调整天线的相位，进而达到调整波束方向的目的。如图1所示，箭头方向为形成的指向接收端的波束方向，θ表示形成的指向接收端的波束的方向。同样地，在终端设备作为接收端的情况下，该终端设备也可以通过调整各天线的相位，使到达各天线的信号波峰和波谷分别叠加，来形成指向发送端的波束，从而使得能够有效地接收信号。即终端设备作为接收端的情况下，该终端设备通过形成不同方向的接收波束，尝试从不同方向上接收信号，从而得到接收能量最好的方向来接收信号。因此，本申请实施例可在波束赋形的技术上形成的指向接收端的波束。
在收发天线规模较大时，基于降低成本和实现的复杂度的考虑，一般要使用模拟波束收发信号。其中，模拟波束使用的天线阵列结构如图2所示，具体地，图2中波阵面为天线阵列的接收平面，天线孔径为天线阵列中各天线阵子的间距，受空间传播路径影响，终端设备发射的信号并不是正对着波阵面，各天线接收同一信号时存在相位差，因此可通过移相器来调节到达各天线的波形相位，使相互对齐。即终端设备使用一组等间距的天线，在每个天线(或每组天线)对应的射频通路上配置移相器，通过改变各接收天线的相位，达到调整波束方向的目的。其中，终端设备的每个天线阵列中所有工作的天线对应的移相器配置参数，称为模拟波束的码本。即在天线阵列中，可通过改变码本配置生成不同的模拟收发波束，也就是说，码本的配置决定了波束的方向。可以理解的是，本申请实施例中的模拟波束是通过模拟方式生成波束。尽管模拟波束和数字波束都属于波束赋形技术，但是以模拟方式生成波束不同于以数字方式生成波束，两者的具体实现方式不同。可理解， 本申请实施例是在模拟波束的场景下示出的信号接收方法。
参见图3，图3通过仿真示出了不同的天线数量对波束形状和增益的影响。其中，横轴表示波束的覆盖范围，纵轴表示信号增益。从中可以看出，天线的数量和终端设备获得的信号增益成正比，和天线形成的波束的空间覆盖范围成反比。也就是说，天线的数量越多，终端设备获得的信号增益就越强，但是该天线形成的波束的覆盖范围就越窄。在终端设备作为接收端时，同时工作的天线数量直接决定了射频前端器件的功耗大小。因此在上述情况下，本申请实施例提出了一种信号接收方法，能够有效地降低射频前端器件的功耗，避免终端设备中的天线全部用来接收信号时的功耗损失。
本申请实施例中，天线阵列面板中的各天线可配置独立开关或多个天线共享配置开关，这样可以依据终端设备所在工作场景的信号强度信息的不同，来设置不同数量的天线参与信号的收发。可理解的是，上述描述也可以理解为一个移相器对应一个天线，或者一个移相器对应多个天线。参见图4，图4是本申请实施例提供的一种天线阵列的结构示意图。其中，终端设备通过一定数量的天线接收到信号后，可以将通过该一定数量的天线接收到的信号进行合并，从而发送到射频集成电路(radio frequency integrated circuit，RFIC)。可理解，图4中示出的是多个天线共享一个配置开关，但是不应理解为对本申请具有限定，如图4中一个开关也可对应一个天线(图中未示出)。具体地，图中一个开关对应了3个天线或2个天线，或者，也可理解为一个移相器对应2个天线，或者一个移相器对应3个天线。可以理解的是，图4仅为一种示例，不应将图4中数量上的对应关系理解为对本申请实施例具有限定。
同时参见图5，图5是本申请实施例提供的一种方向包含关系的示意图，图中示出了一个波束和三个波束在空间覆盖面上的包含关系。相对来说，无颜色波束对应的天线数量小于条纹色波束对应的天线数量。若无颜色波束对应的天线为第一天线，条纹色波束(其中的一个)对应的天线为第二天线，则从中可看出，第一天线形成的波束与第二天线形成的波束在空间覆盖面上具有包含关系。如下表1所示，表中示出了不同天线形成的波束在空间覆盖面上的方向包含关系，其中，终端设备可以通过该方向包含关系来为不同天线配置码本。可以理解的是，表1仅仅为一个示例，不应将表1示出的天线理解为对本申请实施例具有限定意义。
表1
天线数量 码本索引 方向包含
4 Cb41 Cb81，Cb82…
4 Cb42 Cb83，Cb84…
8 Cb81 Cb161,…
举例来说，终端设备可通过码本Cb41和码本Cb42分别为四个天线对应的移相器配置参数，且通过码本Cb41配置的天线形成的波束方向与通过码本Cb42配置的天线形成的波束方向不同。可理解，该四个天线对应的移相器可能为一个移相器，也可能为两个移相器，又或者为四个移相器等等，本申请实施例不作限定。终端设备可通过码本Cb81和码本Cb82分别为八个天线对应的移相器配置参数，且通过码本Cb81配置的天线所形成的波束方向与通过码本Cb82配置的天线所形成的波束方向不同。可理解，该八个天线对应的移相器可能 为八个移相器，也可能为六个移相器，又或者为四个移相器等等，本申请实施例不作限定。
其中，通过码本Cb81配置的天线形成的波束可包含在通过码本Cb41配置的天线形成的波束中。为了更形象地说明本申请实施例所描述的方向包含关系，现以图5为例来说明，如无颜色波束可为通过码本Cb41配置的天线形成的波束，而条纹色波束可分别为通过码本Cb81、码本Cb82和码本Cb83配置的天线形成的波束。也就是说，无颜色波束可为四个天线形成的波束，条纹色波束可分别为八个天线形成的不同方向的波束。因此从中可看出，四个天线形成的波束与八个天线形成的波束可具有包含关系。可理解，以上仅为示例，在具体实现中，四个天线形成的波束可能不是图5所示的大小或形状，以及八个天线形成的各个波束也可能不是图5所示的大小或形状。可以理解的是，表1所示的方向包含关系表仅为一种示例，在具体实现中，可能不止这些方向包含关系，因此，不应将表1所示的内容理解为对本申请具有限定意义。
其中，终端设备可以在选择不同天线时，可以依据表1来配置码本，以达到动态改变终端设备的波束的形状。
在上述所描述的背景的基础上，参见图6，图6是本申请实施例提供的一种信号接收方法的流程示意图，该信号接收方法可应用于终端设备，该终端设备可以为任意具有天线的设备，如该终端设备可以为手机、平板计算机、个人数字助理等智能终端。具体地，该终端设备是一种具有无线收发功能的设备，可以部署在陆地上，包括室内或内外、手持、穿戴或车载。也可以部署在水面上(如轮船等)。还可以部署在空中(如飞机、气球等)。该终端设备除了上述智能终端，还可以是虚拟现实(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)中的无线终端等等具有收发功能的终端。如图6所示，该信号接收方法至少包括以下步骤：
601、通过第一天线获取终端设备所在工作场景的信号强度信息，上述第一天线包含第一数量的天线。
本申请实施例中，终端设备所在工作场景可具体分为终端设备驻留服务小区的场景和终端设备未驻留服务小区的场景。其中，在终端设备驻留服务小区的情况下，信号强度信息为该服务小区的信号强度；在终端设备未驻留服务小区的情况下，信号强度信息可为终端设备在目标方位上搜索到的信号强度。可理解，在终端设备未驻留服务小区的情况下，该终端设备需要搜索服务小区，且该终端设备未搜索到服务小区，但是在目标方位上搜索到的信号强度。
其中，第一天线包含第一数量的天线，该第一数量可为预设的天线的数量，如终端设备出厂设置的天线的数量；或者，也可以为终端设备根据当前所在的工作场景而自动设置的天线数量等等，本申请实施例对于该第一数量不作限定。
602、根据上述信号强度信息确定第二天线；其中，上述第二天线为上述终端设备中的部分或全部天线，上述第二天线包含第二数量的天线，上述第一数量与上述第二数量不同。
其中，终端设备通过第一天线获取信号强度信息后，便可以依据该信号强度信息来确定第二天线，也就是说，终端设备所获取的信号强度对应了终端设备的天线中的第二天线，也即终端设备可以依据信号强度来确定使用多少天线来接收信号。
具体地，上述根据上述信号强度信息确定第二天线包括：
根据上述信号强度信息确定待调整的信号增益；
根据上述待调整的信号增益和上述第一天线确定上述第二天线。
本申请实施例中，终端设备在获取到信号强度信息后，可以对比该信号强度信息是否匹配当前的业务需求，在该信号强度信息不匹配当前的业务需求的情况下，则说明通过第一天线所获得的信号增益已无法匹配当前的业务需求，因此该终端设备就需要调整天线为第二天线，从而使得通过第二天线获得的信号增益能够匹配当前的业务需求。具体地，当前的业务需求可为以下任意一种：驻留服务小区的需求、进行业务的需求、打电话的需求、上网的需求等。可以理解，以上仅为示例，在具体实现中，还可以包括更多的需求，又或者还可以细分为其他需求，本申请实施例对于以上示例不作限定。可理解，当前的业务需求可以理解为终端设备正在进行的业务的需求。可理解，终端设备中可以存储信号强度与业务需求之间的关系，以及待调整的信号增益与天线数量之间的关系，从而可以使得终端设备在确定待调整的信号增益之后，能够直接根据待调整的信号增益与天线数量之间的关系来确定第二天线，提高确定第二天线的效率。
举例来说，参见表2，表2示出了待调整的信号增益与天线数量之间的相对关系。
表2
天线数量 待调整的信号增益(db)
2 3
4 3
8 3
16 3
… …
如第一天线的数量为2，终端设备确定的待调整的信号增益为3db，则根据表2，可以确定第二天线的数量为4。又如，第一天线的数量为4，终端设备确定的待调整的信号增益为3db，则可以确定第二天线的数量为8。又如，第一天线的数量为4，终端设备确定的待调整的信号增益为6db，则可以确定第二天线的数量为16。可理解，以上是在待调整的信号增益为需要增加的信号增益的情况下示出的，在具体实现中，也可能需要降低信号增益。可理解，在具体实现中，也可能不止以上几种天线数量的变化，还可能有其他数量的变化。在包含其他数量变化时，可根据天线与增益之间的关系，来得到与表2对应的关系图。举例来说，从N1个天线切换到N2个天线，则N1天线与N2天线之间的信号增益差值的计算方式可为10log(N1/N2)。通过计算信号增益差值，则终端设备在需要增加信号增益时，可直接依据该信号增益差值以及第一天线确定第二天线。可理解的是，在计算信号增益差值时，还可以用其他方式来计算，如通过信道误码率等，本申请不作唯一性限定。可理解，以下将以表2为例来说明本申请实施例所提供的信号接收方法。
在具体实现中，在不同的场景下，终端设备可能需要不同的信号强度来确定不同的待 调整的信号增益。因此，本申请实施例还提供了一种如何确定待调整的信号增益的方法，如下所示：
上述工作场景为驻留在服务小区，上述信号强度信息用于指示上述服务小区所提供的信号强度，上述根据上述信号强度信息确定待调整的信号增益包括：
在上述信号强度小于第一阈值时，确定待增加的信号增益作为上述待调整的信号增益，上述第二天线的数量大于上述第一天线的数量；
在上述信号强度大于第二阈值时，确定待降低的信号增益作为上述待调整的信号增益，上述第二天线的数量小于上述第一天线的数量。
本申请实施例中，第一阈值可以小于等于第二阈值。具体地，该第一阈值与该第二阈值可以根据终端设备当前的业务需求自动配置，更具体地，不同的业务也可以对应不同的第一阈值和第二阈值。其中，在终端设备通过第一天线所获取的信号强度小于第一阈值时，则说明通过第一天线所获得的信号增益不能满足当前的业务需求，终端设备需要获得更大的信号增益，进而该终端设备便可以根据待增加的信号增益以及第一天线确定第二天线。至于增加多少信号增益，则该终端设备可以根据当前的业务需求以及信号强度来确定。参见表3，表3示出了信号强度与业务之间的关系，举例来说，终端设备当前正在打电话，则信号强度需要大于等于-110。而终端设备通过第一天线获得的信号强度为-115，则终端设备可以确定需要增加信号增益，如为3db，则该终端设备可以根据3db以及第一天线确定第二天线。可理解的是，若增加3db的信号增益后，所获得的信号强度仍然小于第一阈值，则该终端设备还可以再增加3db的信号增益，即再增加天线的数量，最后所确定的天线即为第二天线。
可以理解的是，具体实现中，在增加天线数量时，第二天线的最高数量具体为多少，本申请实施例不作限定，该第二天线的数量可为终端设备天线数量的最高规格。可以理解的是，本申请实施例中信号强度的单位为dBm，以上未示出，但不应理解为对本申请实施例具有限定。
表3
信号强度(dBm) 满足的业务
>-115 满足小区驻留业务
>＝-110 满足打电话要求
>＝-108 满足上网要求
>＝-90 可满足所有业务要求
其中，在终端设备通过第一天线所获取的信号强度大于第二阈值时，则说明通过第一天线所获得的信号增益能够满足当前的业务需求，则终端设备可以降低信号增益，即根据待降低的信号增益以及第一天线确定第二天线。举例来说，终端设备当前正在打电话，信号强度为大于等于-110。而终端设备通过第一天线获得的信号强度为-108，则从节省功耗角度，该终端设备可以降低信号增益，如降低3db，则该终端设备便可以根据3db以及第一天线确定第二天线。可理解，表3所示出的例子仅为示例，不应理解为对本申请实施例的限定。
可理解的是，上述根据待调整的信号增益以及第一天线确定第二天线的具体实现方式， 可以参考前述实施例的描述，这里不再详述。
具体地，本申请实施例还提供了一种如何确定待调整的信号增益的方法，如下所示：
上述工作场景为未驻留在服务小区，上述信号强度信息用于指示该终端设备在目标方位上搜索到的信号强度，上述根据上述信号强度信息确定待调整的信号增益包括：
根据上述信号强度确定待增加的信号增益作为上述待调整的信号增益，上述第二天线形成的波束指向上述目标方位，上述第二天线的数量大于上述第一天线的数量。
本申请实施例中，终端设备在目标方位上搜索到信号强度时，则可能是由于终端设备获得的信号增益不够，而导致搜索遗漏，因此可以增加信号增益，如增加天线的数量，从而再通过第二天线获取信号强度。其中，终端设备可以增加3db的信号增益，也可以增加6db的信号增益。从而根据待增加的信号增益以及第一天线来确定第二天线。可理解，第二天线形成的波束指向目标方位，从而可以使得该第二天线在目标方位上有针对性地获取信号强度。其中，根据待增加的信号增益以及第一天线确定第二天线的具体实现方式，可以参考前述实施例，这里不再详述。
在终端设备未驻留服务小区的情况下，第一天线的数量小于第二天线的数量。在终端设备上电开机初始搜索服务小区的情况下，该终端设备可以先通过第一天线来进行全方位的搜索，由于第一天线的数量小于第二天线的数量，因此，第一天线形成的波束的宽度大于第二天线形成的波束的宽度，这样在终端设备初始搜索时，便可以快速地完成一轮全方位搜索过程。如果搜索失败，且在目标方位上搜索到信号强度，则可以增加天线的数量，使用第二天线进行搜索。同样地，在终端设备驻留服务小区的波束跟踪丢失时，该终端设备也可以先通过第一天线进行搜索，若搜索失败，且在目标方位上搜索到信号强度，则可以通过第二天线进行搜索。可理解，第一天线和第二天线可以为定向天线，以及第一天线和第二天线之间存在数量上的区别，但是第一天线和第二天线在类型和/或功能上是否完全一致，本申请实施例不作限定。
具体地，本申请实施例中，上述工作场景包括：
初始搜索上述服务小区；或者
上述服务小区的波束跟踪丢失；或者
小区切换且未接入上述服务小区。
其中，在终端设备进行小区切换，且未接入服务小区的场景，可以包括：终端设备位置变换时，需重新选择服务小区，且未接入新的服务小区的场景；或者，也可以包括：终端设备当前的服务小区的信号强度信息变差，需重新选择服务小区，且未接入新的服务小区的场景。在上述情况下，在终端设备搜索失败时，则终端设备可以将天线由第三天线切换为第四天线。
本申请实施例中，在工作场景为未驻留在服务小区时，还可以通过设置阈值来确定是否需要调整信号增益。如下所示：
上述工作场景为未驻留在服务小区，上述信号强度信息用于指示该终端设备在目标方位上搜索到的信号强度，上述根据上述信号强度信息确定待调整的信号增益包括：
在上述信号强度大于第三阈值的情况下，根据上述信号强度确定待增加的信号增益作为上述待调整的信号增益，上述第二天线形成的波束指向上述目标方位，上述第二天线的 数量大于上述第一天线的数量。
其中，信号强度是否超过第三阈值，可以由接收的信号强度指示(received signal strength indication，RSSI)来衡量，在终端设备检测到目标方位的RSSI较强(大于第三阈值)的情况下，但是没有接收到波束搜索需要的信息(即未搜索到服务小区的波束)时，则可能是由于获得的信号增益不够而导致无法搜索成功，因此，通过增加天线的数量，可以增加接收增益。
本申请实施例中，通过设置第三阈值，可以进一步增加信号增益不够的可能性，从而使得终端设备通过增加信号增益而搜索到服务小区的可能性增大，进而提高终端设备的搜索效率。可以理解的是，本申请实施例对于目标方位不作唯一性限定，该目标方位可以为任意检测到信号强度超过第三阈值的方位。本申请实施例中，第三阈值可以预先预置于终端设备中，如终端设备出厂时设置等。
603、为上述第二天线的移相器配置码本。
具体地，上述为上述第二天线的移相器配置码本包括：
依据方向包含关系为上述第二天线的移相器配置码本，上述方向包含关系中包含上述第一天线形成的波束与上述第二天线形成的波束在空间覆盖面上的包含关系。
本申请实施例中，第一天线形成的波束与第二天线形成的波束在空间覆盖范围上存在对应关系，如图5所示，若第二天线对应图5中的条纹色波束对应的天线，第一天线对应图5中无颜色波束对应的天线，则可以看出，第一天线形成的波束在空间覆盖面上包含了第二天线形成的波束。
本申请实施例中，在终端设备已驻留服务小区的情况下，在终端设备确定第二天线之后，就需要从第一天线切换为第二天线，其中，第二天线的数量大于第一天线的数量。在终端设备由第一天线切换为第二天线的过程中，该终端设备需要根据第一天线形成的波束方向为第二天线配置码本，由于第一天线形成的波束的宽度与第二天线形成的波束的宽度不同，即该终端设备需要在第一天线形成的波束的覆盖宽度范围内部进行细扫对准，从而确定第二天线形成的波束的具体方位。如图5所示，第一天线形成的波束为无颜色波束，第二天线形成的波束则可以在第一天线形成的波束的覆盖范围内进行细扫对准，从而来确定第二天线形成的波束的最终方位。
可理解，在为第二天线的移相器配置码本之后，该终端设备通过第二天线获取到服务小区所提供的信号强度后，该信号强度大于第二阈值，则该终端设备可以根据上述所提供的具体实现方式来确定第三天线，其中，该第三天线的数量小于第二天线的数量。该情况下，终端设备需要从第二天线切换为第三天线，而由第二天线切换为第三天线的过程中，该终端设备可根据方向包含关系直接为第二天线配置码本。可理解，上述第三天线可以与第一天线相同，也可能不同，本申请实施例不作限定。可理解，终端设备未驻留服务小区场景下的码本配置方法，可以参考前述实施例，这里不再详述。
604、通过上述第二天线接收信号。
本申请实施例中，依据终端设备所在工作场景的信号强度信息的不同，来确定第二天线，也就是说，该终端设备所在工作场景的信号强度信息对应了该终端设备的天线中的第二天线；实施本申请实施例，终端设备可以依据自身的需求，开关不同数量的天线，从而 达到动态改变天线数量的目的，不仅能够满足终端设备的收发性能，而且尽最大可能地优化了终端设备的射频前端功耗。
以下将结合具体场景来描述本申请实施例所提供的信号接收方法。
场景一、
参见图7，图7是本申请实施例提供的一种信号接收方法的具体场景示意图，该场景是在终端设备未驻留服务小区的情况下示出的例子，如图7所示，该信号接收方法至少包括：
701、终端设备上电开机初始搜索需驻留小区的波束或驻留小区的波束跟踪丢失。
702、使用第一天线进行搜索。
在终端设备上电开机初始搜索需驻留小区的波束或驻留小区的波束跟踪丢失时，因天线个数少，此时使用少量的天线以形成较宽的波束可以快速完成全方位覆盖的一轮搜索过程。
703、当搜索成功，可继续使用第一天线进行后续通信过程的处理，如使用第一天线接收信号。
可理解，在搜索成功后，该终端设备便测量服务小区的质量，这时，该终端设备便可以利用本申请提供的当终端设备接入服务小区时的方法来实现，这里不再一一详述。
704、当搜索失败(可能因信号增益不够而导致搜索遗漏或确实没有信号)，则检测目标方位的RSSI是否大于第三阈值；若是，则执行步骤705；否则执行步骤706。
705、增加天线数量，使用第二天线进行搜索；其中，该第二天线形成的波束指向目标方位。
706、增加天线数量，使用第四天线再次启动搜索；可以理解的是，步骤706中的第四天线可以与步骤705中的第二天线不同，至少可以在形成的波束方向上可以不同。如第二天线形成的波束指向目标方位，而第四天线形成的波束可以指向其他方位，从而通过该第四天线搜索其他方位上的信号强度。
707、若仍未搜索成功，则再次增加天线的数量进行搜索，直到天线数量增加到终端设备最高规格为止。
本申请实施例中，终端设备通过支持能够动态改变天线的天线阵列，可以在使用第一数量的天线，即第一天线搜索服务小区不成功，但搜索到目标方位上的信号强度时，确定第二天线，通过第二天线搜索服务小区。实施本实施例，在满足终端设备的收发性能的同时，还能够最大化地优化射频前端器件。
场景二、
参见图8，图8是本申请实施例提供的另一种信号接收方法的具体场景示意图，该场景是在终端设备已驻留服务小区的情况下示出的例子，如图8所示，该信号接收方法至少包括：
801、通过第一天线获取服务小区的信号强度，即终端设备处于正常工作场景(包括待机态和连接态)时，按协议要求会周期性测量服务小区的信号强度。
其中，待机态可表示终端设备已接入服务小区，即已该服务小区中的网络设备(如基站)进行连接，但是并没有与该网络设备进行数据(或信令)交互。而连接态则表示终端设备与该网络设备进行了数据(或信令)交互。
802、检测信号强度是否小于第一阈值，若是，则执行803；否则，执行804。
803、确定待增加的信号增益，以及根据表2和第一天线确定第二天线。
804、检测信号强度是否大于第二阈值，若是，则执行805；否则，执行806。
805、确定待降低的信号增益，以及根据表2和第一天线确定第二天线。
806、继续使用第一天线进行后续通信过程的处理，如使用第一天线接收信号。
807、在确定第二天线后，该终端设备便可以通过第二天线获取服务小区的信号强度。
本申请实施例中，终端设备在运行过程中，可以根据信号强度来动态改变天线的数量，信号强度较好时，尽可能使用少量的天线以降低功耗。而在信号强度较差时，使用多数量的天线以获得高的信号增益。
以上为本申请实施例示出的信号接收方法，以下将具体介绍本申请实施例中的信号接收装置。可以理解的是，该信号接收装置是以终端设备为例示出的，如图9所示，该终端设备至少包括：
获取单元901，用于通过第一天线获取上述终端设备所在工作场景的信号强度信息；上述第一天线包含第一数量的天线；
确定单元902，用于依据上述信号强度信息确定第二天线；其中，上述第二天线为终端设备中的部分或全部天线，上述第二天线包含第二数量的天线，上述第一数量与上述第二数量不同；
