Description

一种处理无线信号的方法和装置以及通信设备 技术领域
本申请实施例涉及通信领域，并且更具体地，涉及一种处理无线信号的方法和装置以及通信设备。
背景技术
在无线通信系统中，两个地理位置较近的网络设备同时在相同或邻近的工作频带上分别接收上行信号和发送下行信号时，由于网络设备的发射功率通常远远大于终端设备的发射功率，该下行信号将对该上行信号造成严重的干扰，将导致接收该上行信号的网络设备的前端低噪声放大器(low noise amplifier，LNA)阻塞，无法正常接收信号。因此，在现有技术中，需要工作在相同或邻近工作频带且地理位置较近的网络设备保持相同的传输方向(即同时进行下行传输或同时进行上行传输)来规避下行传输对上行传输造成的干扰。随着无线通信业务范围的扩展，采用同一工作频带且邻近的网络设备在同一时刻的下行业务量和上行业务量差异较大，采用相同的上、下行通信配置的限制将无法满足不同网络设备的业务需求。因此，邻近网络设备采用不同的上下行配置，又可以称为动态时分复用(time division duplexing，TDD)时，如何避免接收上行信号的网络设备因其他网络设备的下行信号的干扰而造成的LNA阻塞无法正常接收信号的情况，成为本领域技术人员亟待解决的问题。
发明内容

根据上述方案，第一网络设备通过检测接收到的其他网络设备发送的信号的干扰(即接收功率)，调节增益控制单元的参数至第一值，使得即使接收终端设备发送的第二信号存在其他网络设备发送的信号的干扰，也不会使得第一网络设备的LNA因干扰过大而造成阻塞。能够有效地减少因邻近网络设备发送的信号干扰过大造成LNA阻塞的情况发生的概率。
作为示例非限定，该第三信号包括该第二网络设备发送的信号和第二信号，其中，该第二网络设备发送的信号可以是该第一信号，也可以是第二网络设备发送的其他信号。
结合第一方面，在第一方面的某些实现方式中，该方法还包括：该第一网络设备通知该终端设备发送该第二信号的发射功率，该发射功率是该第一网络设备根据该接收功率确定的。
根据上述方案，第一网络设备根据干扰信号的功率，调节终端设备发送第二信号的功率，能够提高接收信号的信干噪比SINR。
结合第一方面，在第一方面的某些实现方式中，该接收功率是该第一信号在第二时间间隔内的平均功率。
结合第一方面，在第一方面的某些实现方式中，该接收功率是该第一信号经过该参数为最小值的增益控制单元调节功率后在该第二时间间隔内的平均功率，其中，该最小值为该参数的取值范围中的最小值。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、未来的第五代(5th generation，5G)系统或新无线(new radio，NR)，车到其它设备(Vehicle-to-X V2X)，其中V2X可以包括车到互联网(vehicle to network，V2N)、车到车(vehicle to-vehicle，V2V)、车到基础设施(vehicle to infrastructure，V2I)、车到行人(vehicle to pedestrian，V2P)等、车间通信长期演进技术(Long Term Evolution-Vehicle，LTE-V)、车联网、机器类通信(machine type communication，MTC)、物联网(Internet of Things，IoT)、机器间通信长期演进技术(long term evolution-machine，LTE-M)，机器到机器(machine to machine，M2M)等。

本申请实施例中的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、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，终端设备还可以是物联网(internet of things，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。
应理解，本申请对于终端设备的具体形式不作限定。

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，简称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、媒体接入控制(media 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。

S210，核心网设备向网络设备发送指示信息。
S220，网络设备A接收其他网络设备发送的信号#1。
S230，网络设备A检测信号#1的接收功率。
网络设备A接收邻近的其他网络设备发送的信号#1，以便网络设备A检测该其他网络设备发送的信号对网络设备A接收信号的干扰大小。网络设备A检测得到信号#1的接收功率，网络设备A根据信号#1的接收功率确定其他网络设备发送的信号对网络设备A接收信号的干扰大小。
作为示例非限定，信号#1的接收功率可以是信号#1在时间间隔A内的平均功率。在本申请中，时间间隔为特定时间长度的一段连续时间。
一种实施方式中，网络设备A根据核心网设备发送的干扰检测指示，检测该信号#1的接收功率，也就是说，网络设备A在S210中接收核心网设备发送的指示信息中包括该干扰检测指示，该干扰检测指示用于触发该网络设备A检测一次该信号#1的接收功率，该检测方式也可以称作非周期检测或触发检测。也就说，仅当网络设备A接收到核心网设备发送的干扰检测指示后，网络设备A即检测一次信号#1的接收功率，根据本次检测到的信号#1的接收功率调整该增益控制单元的参数。网络设备A在没有接收到核心网设备发送的该干扰检测指示的情况下，不检测信号#1的接收功率。
作为示例非限定，该干扰检测指示可以是核心网设备的操作管理维护(operation,administration and maintenance，OAM)网络单元向该网络设备A发送的指示。
例如，网络设备A接收到该核心网设备的OAM网络单元发送的干扰检测指示，指示网络设备A检测信号#1的接收功率，则网络设备A检测信号#1在时间间隔A(即，第二时间间隔的一例)内的平均功率。其中，相邻两次干扰检测指示的时间间隔不小于时间间隔A。可选地，干扰检测指示还可以指示时间间隔A的起始时刻和/或终止时刻。
另一种实施方式中，S210中核心网设备向网络设备A发送的指示信息中包括时间间隔B，该指示信息指示网络设备A以时间间隔B(即，第一时间间隔的一例)为周期，周期性地检测该信号#1的接收功率。该检测方式可以称为周期性检测。网络设备A在每个周期结束时根据检测得到的该周期内的信号#1的接收功率，调整增益控制单元的参数。该周期内的信号#1的接收功率可以是该周期内信号#1在时间间隔A内的平均功率，其中，时间间隔A小于时间间隔B的时间长度。
作为示例非限定，时间间隔B可以是核心网设备向该网络设备配置或指示的。可选地，该时间间隔B可以由核心网设备的OAM网络单元向该网络设备配置或指示的。
作为示例非限定，核心网设备向网络设备A发送的指示信息为5G通信系统中的下一代(next generation，NG)接口消息。
在本申请方案中，网络设备A包括增益控制单元，该增益控制单元用于根据其被设置的参数值调整该增益控制单元的输入信号的功率。该被设置的参数值为该参数的取值范围中的一个值，该增益控制单元的参数值为一个缩放系数，增益控制单元根据其被设置的参数值将输入信号的功率放大或缩小。该增益控制单元与LNA相连接，增益控制单元的输出信号将输入至LNA，因此，该增益控制单元可以对输入的信号的功率进行调整，使得其调整功率后的信号进入LNA后，LNA可以工作在线性区域，降低因干扰过大而造成的LNA阻塞的概率。
作为示例非限定，该参数的取值可以为大于1的实数，也可以为大于0且小于1的实数。当该参数取大于1的实数时，该增益控制单元将输入信号的功率放大；当该参数取大于0且小于1的实数时，该增益控制单元将输入信号的功率减小。
作为示例非限定，该参数的取值还可以表示为分贝(decibel，dB)值的形式，该参数的取值可以为正分贝值，也可以为负分贝值。当该参数取正分贝值时，该增益控制单元将输入信号的功率放大；当该参数取负分贝值时，该增益控制单元将输入信号的功率减小。
一种实施方式中，网络设备A在接收该信号#1前将该增益控制单元的参数设置为取值范围中的最小值，使增益控制单元根据该最小值调整该信号#1的功率，该信号#1的接收功率为调整功率后的信号#1的平均功率，例如图3所示，信号#1可以在网络设备A中通过参数为最小值的增益控制单元调整功率后由功率检测单元检测得到接收功率，网络设备A根据该接收功率调节增益控制单元的参数的值。将增益控制单元的参数设置为最小值，使网络设备A能够较准确地检测信号#1的接收功率，以便较准确地估计信号#1的干扰大小，但本申请不限于此。
在本申请方案中，网络设备A在第一频带接收信号，其中，频带为一个频率到另一个频率之间连续的一段频率间隔，也可以称为频率带宽。信号#1可以包括其他网络设备在该第一频带发送的信号，可以称为同频信号，也可以包括其他网络设备在第一频带以外的频带发送的信号，也可以称为异频信号，或者，信号#1即包括其他网络设备发送的同频信号又包括其他网络设备发送的异频信号，本申请对此不作限定。
例如，信号#1可以包括网络设备B(即其他网络设备包括网络设备B)在第一频带发送的信号B，信号B为网络设备A的接收信号的同频干扰信号。网络设备A根据检测得到的信号B的接收功率调节增益控制单元的参数。
再例如，信号#1可以包括网络设备C(即其他网络设备包括网络设备C)采用第二频带的频率资源发送的信号C，信号C为网络设备A的接收信号的异频干扰信号。网络设备A根据检测得到的信号B的接收功率调节增益控制单元的参数。
作为示例非限定，第二频带可以是第一频带的相邻频带。例如图4所示，第一频带为频率f2到频率f3的一段频率间隔，第二频带可以是最低频率大于或等于第一频带的最高频率的相邻频带，如图4中的示例1所示，第二频带为频率f3到频率f4的一段频率间隔，第二频带的最低频率f3等于第一频带的最高频率f3，也就是说，第二频带为频率高于第一频带的高频相邻频带。第二频带也可以是最高频率小于或等于第一频带的最低频率的相邻频带，如图4中的示例2所示，第二频带为频率f1到频率f2的一段频率间隔，第二频 带的最高频率f2等于第一频率的最低频率f2，也就是说，第二频带为第一频带的低频相邻频带。
再例如，信号#1既包括网络设备B在第一频带的频率资源发送的信号B又包括网络设备C在第二频带上发送的信号C，即其他网络设备既包括网络设备B又包括网络设备C，网络设备A根据检测得到的既包括信号B又包括信号C的信号#1的接收功率调节增益控制单元的参数。例如，非周期性检测的情况下，网络设备A接收到核心网设备发送的干扰检测指示后，检测包括信号B和信号C的信号#1的接收功率。再例如，在周期性检测的情况下，网络设备A在一个周期结束时，根据该周期内包括信号B和信号C的信号#1在时间间隔A中的平均功率，调节增益控制单元的参数。
信号#1还可以包括同一网络设备发送的同频信号和异频信号，但本申请不限于此。例如，信号#1包括网络设备B在第一频带发送的信号B和在第二频带发送的信号C，网络设备A根据该网络设备B发送的包括信号B和信号C的信号#1的接收功率，调节增益控制单元的参数。
S240，网络设备A根据信号#1的接收功率调节增益控制单元的参数为第一值。
S250，网络设备A根据信号#1的接收功率，确定终端设备的发送功率
S260，网络设备A通知终端设备发送信号#2(即，第二信号的一例)的发射功率。
S270，网络设备A接收终端设备信号#2。
S280，网络设备A的增益控制单元根据第一值调整信号#3的功率。
网络设备A在S230检测得到信号#1的接收功率后，根据该接收功率将增益控制单元的参数调节为第一值。作为示例非限定，该第一值使得信号经过参数为第一值的增益控制单元后功率变小，也就是说，该第一值为大于0且小于1的实数或者负分贝值。
在S270中，网络设备接收终端设备发送的信号#2得到信号#3(即，第三信号的一例)，其中信号#3包括终端设备发送的信号#2和其他网络设备发送的信号，即信号#2的干扰信号，其中，该其他网络设备是发送信号#1的网络设备。该信号#3经过参数为第一值的增益控制单元调整功率后输出信号#4(即，第四信号的一例)，该第一值使得信号#4输入LNA后LNA工作在线性区域，例如图5所示。也就是说，网络设备A根据信号#1的接收功率确定的增益控制单元的参数的第一值，能够使信号#3经过参数为第一值的增益控制单元调整功率输入LNA后，LNA工作线性区域。优选地，经该参数为第一值的增益控制单元调整功率后输出的信号#4，输入LNA后使得LNA工作在最佳状态，即放大系数为线性区域的最大值。
可选地，在网络设备A根据信号#1的接收功率调节增益控制单元的参数为第一值后，网络设备A执行S250，根据该信号#1的接收功率确定终端设备发送信号#2的发射功率，并在S260中通知终端设备发送信号#2的发射功率，该发射功率使得存在其他网络设备的干扰的情况下，提高网络设备A接收信号#2的接收信号的信干噪比(signal interference noise ratio，SINR)。例如，在不存在其他网络设备的干扰的情况下，终端设备以发射功率A向网络设备A发送信号，当存在其他网络设备的干扰的情况下，网络设备A根据其他网络设备发送的信号#1的接收功率调节增益控制单元的参数值后，通知终端设备发送信号#2的发射功率B，终端设备接收到网络设备A发送的该通知后，采用发射功率B发送信号#2，该发射功率B大于发射功率A。通过增加终端设备的发射功率来提升SINR， 是因为工业场景下，终端设备通常不会采用最大发射功率发送信号，因此，有余地调整终端设备发射功率。
另外，当网络设备A在一次检测到的信号#1的接收功率A时，且网络设备A根据接收功率A将增益控制单元的参数调节为第一值A，而在下一次检测到的信号#1的接收功率B小于接收功率A时，将增益控制单元的参数调节为第一值B，若该第一值表示为实数，则该第一值B为大于0且小于1的实数，且该第一值B大于第一值A；若该第一值表示为分贝值，则该第一值B为负数，且该第一值B小于第一值A。并且网络设备A通知终端设备发送信号#2的发射功率，该发射功率小于原发射功率，使网络设备A接收信号#2得到的接收信号的SINR满足需求的同时，能够降低终端设备的功率消耗。其中，下一次可以是非周期性检测的下一次被触发的检测，也可以是周期性检测的下一个周期的检测，但本申请不限于此。
根据本申请的方案，第一网络设备通过检测接收其他网络设备发送的信号的干扰，即接收功率，调节增益控制单元的参数至第一值，使得即使接收终端设备发送的第二信号存在其他网络设备发送的信号的干扰，也不会使得第一网络设备的LNA因干扰过大而造成阻塞。能够有效地减少因邻近网络设备发送的信号干扰过大造成LNA阻塞的情况发生的概率。另外，第一网络设备可以根据干扰信号的功率，调节终端设备发送第二信号的功率，能够提高接收信号的信干噪比SINR。
