Description

信号处理方法、设备及系统 技术领域
本申请涉及通信技术领域，尤其涉及信号处理方法、设备及系统。
背景技术
随着无线通信的快速发展，人们早已不满足仅限于人与人的通信，物联网(internet of things，IoT)技术应运而生，并且其市场需求增长迅猛。IoT设备多是比较小巧、电池供电的系统，如智能抄表系统，需要对水、电煤气等使用情况进行周期性监测并上报，这些设备通常部署在地下室，墙壁中等无线信号覆盖很差的地方。因此在IoT通信系统设计时，覆盖增强作为一个基本的设计需求，在空口单跳要求达到20dB的覆盖增强。
IoT单跳20dB的覆盖增强，能满足大部分场景下的覆盖要求，但是在一些特殊的场景下，比如对于楼宇等多层分布的场景下，如果基站位于楼顶，则靠近基站近的楼层的IoT终端设备可以被服务到，但是离基站比较远的楼层的IoT终端设备，可能无法被服务到。此外，还有一些场景，比如一些煤气表等在比较深的地下，也可能一跳无法到达。而在这些场景下，有线的回程链路的部署也比较困难。因此为了进一步解决终端设备的深覆盖问题，可以引入中继机制来解决。
通常中继分为三种，包括层1中继(relay)、层2relay和层3relay。其中，层1relay又名转发器(repeater)、直放站或中继器等，主要功能是对衰减信号进行放大，重新发送或者转发，解决终端设备的深覆盖问题。图1给出了通常的中继系统的网格架构示意图。从图1中可以看出，repeater是中继节点，该repeater节点到施主演进的节点B(donor evolution node B，DeNB)之间是通过Un接口连接的，该repeater节点到远端(remote)终端设备之间是通过Uu接口连接的。
然而，repeater可能对DeNB和其他终端设备产生噪声干扰。
发明内容

在一种可能的设计中，本申请实施例提供的通信系统还可以包括网络设备。其中，网络设备，用于接收或发送第一信号；第二设备，还用于在该第一时域资源位置放大该第一信号。可选的，网络设备还用于发送第二信号，该第二信号包括用于指示传输第一信号的第一时域资源位置的信息。

具体实施方式
为了方便理解本申请实施例中的方案，首先给出相关技术的简要介绍或定义如下：
第一，搜索空间(search space，SS)：
搜索空间定义了检测物理下行控制信道(physical downlink control channel，PDCCH)的时域上的可能性。以NB-IoT系统中的窄带物理下行控制信道(narrowband physical downlink control channel，NPDCCH)为例，终端设备需要监听一个NPDCCH候选集合以获取下行控制信息(downlink control information，DCI)，该NPDCCH候选集合称为NPDCCH搜索空间。其中，NPDCCH搜索空间的资源周期性分布。网络设备可以通过系统信息块(system information block，SIB)或者无线资源控制(radio resource control，RRC)信令向终端设备指示NPDCCH搜索空间的周期和NPDCCH搜索空间在每个周期内的起始位置，终端设备根据网络设备的指示在NPDCCH搜索空间内盲检测NPDCCH。
其中，系统信息块或者RRC信令中携带参数R max、G和α offset。R max表示NPDCCH搜索空间的最大重复次数。终端设备接收到系统信息块或者RRC信令后，将R max和G的乘积确定为NPDCCH搜索空间的周期；将R max确定为NPDCCH搜索空间在每个NPDCCH搜索空间的周期内的持续时长；将R max、G和α offset三者的乘积确定为NPDCCH搜索空间的周期的起始位置与NPDCCH搜索空间的起始位置在时域上的间隔，即G*R max*α offset表示在时域上从NPDCCH搜索空间的周期的起始位置向后偏移G*R max*α offset长度为NPDCCH搜索空间的起始位置。
一个NPDCCH搜索空间的周期内可以有多个NPDCCH候选。图2示例出了本申请实施例所涉及的一种NPDCCH候选的示意图。其中，NPDCCH搜索空间的周期为G*R max，NPDCCH搜索空间在G*R max内的持续时长为R max个有效子帧，NPDCCH搜索空间的周期的起始位置与NPDCCH搜索空间的起始位置在时域上的间隔为G*R max*α offset，一个NPDCCH搜索空间的周期内最多可以有15个NPDCCH候选，每个NPDCCH候选的重复等级(repetition level)为R，第0至第7个候选中的每个候选的重复等级R等于R max/8，第0至第7个候选中的每个候选在时域上的长度等于R max/8(也即是8分之R max)个有效子帧，第8至第11个候选中的每个候选的重复等级R等于R max/4，第8至第11个候选中的每个候选在时域上的长度等于R max/4(也即是4分之R max)个有效子帧，第12至第13个候选中的每个候选的重复等级R为R max/2，第12至第13个候选中的每个候选在时域上的长度等于R max/2(也即是2分之R max)个有效子帧，第14个候选的重复等级R等于R max，第14个候选在时域上的长度等于R max个有效子帧。
需要说明的是，本申请实施例中，有效子帧的定义和具体的通信系统有关。以NB-IoT系统为例，有效子帧可称为NB-IoT下行子帧。在以下情形中，NB-IoT系统中的终端设备应当假设一个子帧为NB-IoT下行子帧：
比如，终端设备确定不包括窄带主同步信号(narrowband primary synchronization signal，NPSS)，或者窄带辅同步信号(narrowband secondary synchronization signal，NSSS)，或者窄带物理广播信道(narrowband physical broadcast channel，NPBCH)，或者NB系统信息块类型(system information block type1-NB)传输的子帧为NB-IoT下行子帧。或者，终端设备接收配置参数，该配置参数用于配置NB-IoT下行子帧。进而，终端设备根据该配置参数，可以确定NB-IoT下行子帧。其中，该配置参数可以通过系统信息块或者RRC信令配置，本申请实施例对此不作具体限定。
以eMTC系统为例，有效子帧可称为带宽减少低复杂度或者覆盖增强(bandwidth-reduced low-complexity or coverage enhanced，BL/CE)下行子帧。其中，BL/CE下行子帧可以通过配置参数进行配置，该配置参数通过系统信息块或者RRC信令配置。
第二，repeater协议栈架构：
图3给出了一种repeater协议栈架构示意图。其中，在面向远端终端设备的Uu口，repeater支持物理(physical，PHY)层的空口协议栈；在面向DeNB的回程链路，repeater支持PHY层的Un空口的传输。此外，由图3可以看出，远端终端设备协议栈从下至上依次包括：PHY层、媒体接入控制(media access control，MAC)层、无线链路控制(radio link control，RLC)层、分组数据汇聚层协议(packet data convergence protocol，PDCP)层、无线资源控制(radio resource control，RRC)层和非接入层(non-access stratum，NAS)；DeNB面向repeater的Un口，DeNB协议栈从下至上依次包括PHY层、MAC层、RLC层、PDCP层和RRC层。DeNB面向移动管理实体(mobile managenment entity)，MME协议栈从下至上依次包括：(level1，L1)层、L2层、网络协议(internet protocol，IP)层、流控制传输协议(stream control transmission protocol，SCTP)层和S1应用协议(S1 application protocol，S1-AP)层；MME面向DeNB的协议栈从下至上依次包括：L1层、L2层、IP层、SCTP层、S1-AP层和NAS层。其中，远端终端设备协议栈、DeNB协议栈和MME协议栈的相关描述可参考通信协议，在此不再详细赘述。
从图1所示的网络架构和图3所示的协议栈架构来看，repeater是一个DeNB和一个终端设备功能的结合。由于存在损耗，在线路上传输的信号功率会逐渐衰减，衰减到一定程度时将造成信号失真，从而会导致接收错误。repeater就是为解决这一问题而设计的，它是局域网环境下用来延长网络距离的最简单最廉价的互联设备，主要完成物理层的功能，负责在两个节点的物理层上按位传递信息，完成信号的复制、调整和放大功能，以此来延长网络的长度。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。其中，在本申请的描述中，除非另有说明，“/”表示前后关联的对象是一种“或”的关系，例如，A/B可以表示A或B；其中A，B可以是单数或者复数。并且，在本申请的描述中，除非另有说明，“多个”是指两个或多于两个。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b，或c中的至少一项(个)，可以表示：a，b，c，a-b，a-c，b-c，或 a-b-c，其中a，b，c可以是单个，也可以是多个。另外，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。同时，在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念，便于理解。
本发明实施例的技术方案可以应用于各种通信系统。例如，可以适用于长期演进(long term evolution，LTE)系统，如NB-IoT系统或者增强的机器间通信(enhanced machine type communications，eMTC)系统；也可以适用于其他无线通信系统，例如全球移动通信系统(global system for mobile communication，GSM)，移动通信系统(universal mobile telecommunications system，UMTS)，码分多址接入(code division multiple access，CDMA)系统或者第五代(5th generation，5G)系统，以及面向未来的通信系统等，本申请实施例对此不作具体限定。其中，本申请实施例中，术语“系统”可以和“网络”相互替换，在此统一说明，以下不再赘述。
如图4所示，为本申请实施例提供的一种通信系统40，该通信系统40包括第一设备401和第二设备402。第一设备401，用于确定传输第一信号的第一时域资源位置，并在第一时域资源位置的起始位置或者起始位置之前向第二设备402发送第一控制信令，第一控制信令用于开启第二设备402的信号放大功能。第二设备402，用于接收来自第一设备401的第一控制信令，并根据第一控制命令开启第二设备402的信号放大功能。其中，该方案的具体实现将在后续方法实施例中详细描述，在此不予赘述。
可选的，本申请实施例中的第一设备可以是终端设备或者终端设备内的芯片。
可选的，本申请实施例中的第二设备可以是层1relay，例如还可以称之repeater、直放站或中继器等，主要功能是对衰减信号进行放大，重新发送或者转发。
可选的，如图4所示，本申请实施例提供的通信系统40还可以包括网络设备404以及一个或多个远端终端设备403。其中，远端终端设备403通过第二设备402与网络设备404建立通信连接，如远端终端设备403通过第二设备402向网络设备404发送第一信号，或者网络设备404通过第二设备402向远端终端设备403发送第一信号等，本申请实施例对此不作具体限定。
通常的repeater一直处于开启的状态，不论是有用信号还是噪声，repeater都会对其进行放大。当DeNB没有发送数据给远端终端设备时，放大的噪声会对DeNB和其他终端设备产生噪声干扰。基于本申请实施例提供的通信系统，由于第一设备可以在传输第一信号的第一时域资源位置的起始位置或者起始位置之前指示第二设备开启信号放大功能，也就是说当有信号需要中转时才进行信号放大，当没有信号需要中转时不需要开启信号放大功能，因此可以避免当DeNB没有发送数据给远端终端设备时，放大的噪声会对DeNB和其他终端设备产生噪声干扰的问题，从而可以降低噪声干扰。
如图5所示，为本申请实施例提供的另一种通信系统50，该通信系统50包括第三设备501和网络设备502。第三设备501，用于确定传输第一信号的第一时域资源位 置，并在第一时域资源位置的起始位置或起始位置之前开启第三设备的信号放大功能。网络设备502，用于接收或发送第一信号。
可选的，本申请实施例中的第三设备可以是上述第一设备和第二设备集成或合一的设备。
可选的，如图5所示，该通信系统50还可以包括一个或多个远端终端设备503。其中，远端终端设备503通过第三设备501与网络设备502建立通信连接，如远端终端设备503通过第三设备501向网络设备502发送第一信号，或者网络设备502通过第三设备501向远端终端设备503发送第一信号等，本申请实施例对此不作具体限定。
可选的，本申请实施例中，网络设备502和远端终端设备501之间可以包括一个或多个第三设备501，该一个或多个第三设备501，可以理解为在网络设备502与远端终端设备503之间增加的一个或多个中继节点设备，负责对无线信号进行一次或者多次的转发，即无线信号要经过多跳才能到达终端设备。以较简单的两跳中继为例，就是将一个“网络设备—远端终端设备”的链路分割为“网络设备—第三设备”和“第三设备—远端终端设备”两个链路，从而有机会将一个质量较差的链路替换为两个质量较好的链路，以获得更高的链路容量及更好的覆盖，从而使得远端终端设备的功耗也得到改善。
通常，repeater一直处于开启的状态，不论是有用信号还是噪声，repeater都会对其进行放大。当DeNB没有发送数据给远端终端设备时，放大的噪声会对DeNB和其他终端设备产生噪声干扰。基于本申请实施例提供的通信系统，由于第三设备可以确定传输第一信号的第一时域资源位置，并在第一时域资源位置的起始位置或起始位置之前开启第三设备的信号放大功能，也就是说当有信号需要中转时才进行信号放大，当没有信号需要中转时不需要开启信号放大功能，因此可以避免当DeNB没有发送数据给远端终端设备时，放大的噪声会对DeNB和其他终端设备产生噪声干扰的问题，从而可以降低噪声干扰。
需要说明的是，本申请实施例中，上述第一设备或第三设备确定的传输第一信号的第一时域资源位置可能是传输第一信号的实际时域资源位置，也可能是包括传输第一信号的实际时域资源位置的一个可能的位置区域。比如，假设第一信号为承载在物理下行控制信道上的下行控制消息，则该第一时域资源位置其实是物理下行控制信道搜索空间，也就是说，需要在该物理下行控制信道搜索空间内一直开启信号放大功能。其中，物理下行控制信道搜索空间的相关描述可参考具体实施方式前序部分，在此不再赘述。或者，比如，假设第一信号为上行数据、下行数据、同步信号、系统信息块或者主信息块(master information，MIB)等，则该第一时域资源位置为传输第一信号的实际时域资源位置，在此统一说明，以下不再赘述。
需要说明的是，本申请实施例中的信号放大功能还可以称之为信号中转功能或者中继功能等，在此统一说明，以下不再赘述。
可选的，本申请实施例中的网络设备，是一种用于与终端设备通信的设备。该网络设备可以是任意一种具有无线收发功能的设备或可设置于该设备的芯片，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)、施主基站(donor evolved nodeB，DeNB)、 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 node B，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，如新空口(new radio，NR)系统中的下一代NB(generation，gNB)或传输点(如TRP或TP)，5G系统中基站的一个或一组(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BBU或分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU实现RRC层和PDCP层的功能，DU实现无RLC层、MAC层和PHY层的功能。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层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，可以将CU划分为接入网中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，在此不做限制。
可选的，本申请实施例中的终端设备或远端终端设备，可以是用于实现无线通信功能的设备，例如终端或者可用于终端中的芯片等。其中，终端可以是LTE系统、NR系统或者未来演进的PLMN中的用户设备(user equipment，UE)、接入终端、终端单元、终端站、移动站、移动台、远方站、远程终端、移动设备、无线通信设备、终端代理或终端装置等。接入终端可以是蜂窝电话、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、个人数字处理(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、车载设备或可穿戴设备，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。终端可以是移动的，也可以是固定的。
可选的，本申请实施例中的网络设备与远端终端设备也可以称之为通信装置，其可以是一个通用设备或者是一个专用设备，本申请实施例对此不作具体限定。
可选的，本申请实施例中的第一设备401、第二设备402或者第三设备501的相关功能可以由一个设备实现，也可以由多个设备共同实现，还可以是由一个设备内的一个或多个功能模块实现，本申请实施例对此不作具体限定。可以理解的是，上述功能既可以是硬件设备中的网络元件，也可以是在专用硬件上运行的软件功能，或者是硬件与软件的结合，或者是平台(例如，云平台)上实例化的虚拟化功能。
例如，本申请实施例中的第一设备401、第二设备402或者第三设备501的相关功能可以通过图6中的通信装置600来实现。图6所示为本申请实施例提供的通信装 置600的结构示意图。该通信装置600包括一个或多个处理器601，通信线路602，以及至少一个通信接口(图6中仅是示例性的以包括通信接口604，以及一个处理器601为例进行说明)，可选的还可以包括存储器603。
处理器601可以是一个通用中央处理器(central processing unit，CPU)，微处理器，特定应用集成电路(application-specific integrated circuit，ASIC)，或一个或多个用于控制本申请方案程序执行的集成电路。

通信接口604，可以是收发模块用于与其他设备或通信网络通信，如以太网，RAN，无线局域网(wireless local area networks，WLAN)等。例如，所述收发模块可以是收发器、收发机一类的装置。可选的，所述通信接口604也可以是位于处理器601内的收发电路，用以实现处理器的信号输入和信号输出。
存储器603可以是具有存储功能的装置。例如可以是只读存储器(read-only memory，ROM)或可存储静态信息和指令的其他类型的静态存储设备，随机存取存储器(random access memory，RAM)或者可存储信息和指令的其他类型的动态存储设备，也可以是电可擦可编程只读存储器(electrically erasable programmable read-only memory，EEPROM)、只读光盘(compact disc read-only memory，CD-ROM)或其他光盘存储、光碟存储(包括压缩光碟、激光碟、光碟、数字通用光碟、蓝光光碟等)、磁盘存储介质或者其他磁存储设备、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其他介质，但不限于此。存储器可以是独立存在，通过通信线路602与处理器相连接。存储器也可以和处理器集成在一起。
其中，存储器603用于存储执行本申请方案的计算机执行指令，并由处理器601来控制执行。处理器601用于执行存储器603中存储的计算机执行指令，从而实现本申请实施例中提供的信号处理方法。
或者，本申请实施例中，也可以是处理器601执行本申请下述实施例提供的信号处理方法中的处理相关的功能，通信接口604负责与其他设备或通信网络通信，本申请实施例对此不作具体限定。

在具体实现中，作为一种实施例，通信装置600可以包括多个处理器，例如图6中的处理器601和处理器608。这些处理器中的每一个可以是一个单核(single-CPU)处理器，也可以是一个多核(multi-CPU)处理器。这里的处理器可以指一个或多个设备、电路、和/或用于处理数据(例如计算机程序指令)的处理核。
在具体实现中，作为一种实施例，通信装置600还可以包括输出设备605和输入设备606。输出设备605和处理器601通信，可以以多种方式来显示信息。
上述的通信装置600可以是一个通用装置或者是一个专用装置。例如通信装置600可以是台式机、便携式电脑、网络服务器、PDA、移动手机、平板电脑、无线终端设备、嵌入式设备或具有图4中类似结构的设备。本申请实施例不限定通信装置600的 类型。
下面将结合图1至图6，对本申请实施例提供的通信方法进行展开说明。
首先给出本申请实施例中需要进行信号放大的第一信号的简单介绍如下：
本申请实施例中的第一信号例如可以包括承载在物理下行共享信道上的上行数据或者承载在物理下行共享信道上的下行数据。此时，指示传输第一信号的第一时域资源位置的信息可以通过解码承载在物理下行控制信道上的下行控制信息获得。
或者，本申请实施例中的第一信号例如可以包括承载在物理下行控制信道上的下行控制信息，此时指示传输第一信号的第一时域资源位置的信息可以通过SIB获得。
或者，本申请实施例中的第一信号例如可以包括同步信号，该同步信号可以包括NPSS或者NSSS。其中，NPSS位于每个无线帧的子帧5，NSSS位于每两个无线帧(偶数无线帧)的子帧9。也可以理解为，传输NPSS和NSSS的第一时域资源位置均为设定时域资源位置。
或者，本申请实施例中的第一信号例如可以包括MIB。其中，在NB-IOT系统中，MIB通过NPBCH承载，位于每个无线帧的子帧0。也可以理解为，传输MIB的第一时域资源位置为设定时域资源位置。
或者，本申请实施例中的第一信号例如可以包括SIB。SIB包括SIB1和其它SIB。这里的其它SIB例如可以包括SIB2、SIB3、SIB4、SIB5、SIB14、SIB15、SIB16、SIB20、SIB22或SIB23。在NB-IOT系统中，SIB1位于无线帧的子帧4，但是传输SIB1的无线帧位置是需要根据MIB的SIB1调度信息确定的。也就是说，在NB-IOT系统中，指示传输SIB1的第一时域资源位置的信息承载在MIB中。而对于其它SIB的传输位置是通过SIB1调度的，也就是说，指示传输其它SIB的第一时域资源位置的信息承载在SIB1中。在LTE系统中，SIB1的时域资源位置是固定的，SIB1的周期为80ms，在每个周期的偶数帧的子帧5上重复发送SIB1。而对于其它SIB的传输位置和周期是通过SIB1调度的，SIB1会指示其他SIB的SI窗口的时域位置和长度，但不会直接指示SI窗口内的哪些子帧调度了其他SIB，SI窗口内哪个子帧上有其他SIB可以通过解码该子帧上的承载在物理下行控制信道上的下行控制信息确定，也就是说，指示传输其它SIB的第一时域资源位置的信息承载在SIB1和承载在物理下行控制信道上的下行控制信息中。
或者，本申请实施例中的第一信号例如可以包括参考信号，该参考信号包括小区特定参考信号(cell reference signal，CRS)、窄带参考信号(narrowband reference signal，NRS)或调制参考信号(demodulation reference signal，DMRS)。其中，参考信号的传输位置可以通过SIB获取，也就是说，指示传输参考信号的第一时域资源位置的信息承载在SIB中。
或者，本申请实施例中的第一信号例如可以包括寻呼消息。终端设备仅在一个不连续接收(discontinuous reception，DRX)周期上的一个寻呼机会(paging occasion，PO)所在的子帧(以下也可以称之为PO位置)为起始子帧的物理下行控制信道搜索空间内以盲检的形式检测物理下行控制信道。而对于网络设备来说，可以在一个DRX周期内配置多个PO，因此在进行信号放大时需要放大这多个PO处的物理下行控制信道。也就是说，这里的传输第一信号的时域资源位置是包括传输第一信号的实际时域 资源位置的一个可能的位置区域，即多个PO位置为起始子帧的物理下行控制信道搜索空间的位置。其中，寻呼的配置信息可以通过SIB获取，如通过SIB2或SIB22获取，也就是说，指示传输寻呼消息的第一时域资源位置的信息承载在SIB中。
或者，本申请实施例中的第一信号例如可以包括随机接入过程中的各个消息。比如，第一信号可以包括随机接入过程中的前导码、随机接入响应(random access response，RAR)、消息3和消息4。其中，随机接入过程的具体流程可参考通常的随机接入流程，在此不再赘述。其中，承载前导码的物理随机接入信道的时域资源位置可以配置在SIB中，如在SIB2/SIB22/SIB23中配置指示传输前导码的第一时域资源位置的信息；指示传输RAR或消息4的第一时域资源位置的信息承载在物理下行控制信道上的下行控制信息中；指示传输消息3的第一时域资源位置的信息承载在RAR中。
需要说明的是，上述包括用于指示传输第一信号的第一时域资源位置的信息的信号也可以称之为第二信号，如在第一信号为承载在物理下行共享信道上的上行数据或者承载在物理下行共享信道上的下行数据时，第二信号为承载在物理下行控制信道上的下行控制信息；或者，在第一信号为参考信号或寻呼消息或随机接入过程中的前导码或承载在物理下行控制信道上的下行控制信息时，第二信号为SIB；或者，在第一信号为SIB1时，第二信号为MIB；或者，在第一信号为其它SIB时，第二信号为SIB1；或者，在第一信号为随机接入过程中的RAR或者消息4时，第二信号为承载在物理下行控制信道上的下行控制信息；或者，在第一信号为随机接入过程中的消息3时，第二信号为RAR，在此统一说明，以下不再赘述。
需要说明的是，本申请实施例中，第一信号的第一时域资源位置可以是超帧粒度的、无线帧粒度的、子帧粒度的、时隙粒度的或者符号粒度的等。也就是说，第一信号的第一时域资源位置可以占至少一个超帧，或者，第一信号的第一时域资源位置可以占至少一个无线帧，或者，第一信号的第一时域资源位置可以占至少一个子帧，或者，第一信号的第一时域资源位置可以占至少一个时隙，或者，第一信号的第一时域资源位置可以占至少一个符号。在此统一说明，以下不再赘述。
其次，对于图4或图5所示的通信系统，给出几种可能的协议栈架构如下：

其中，本申请实施例中，NPDCCH资源5的时域位置指示信息具体可以是DRX周期的大小，寻呼密度(即一个DRX周期中包括的寻呼机会的个数)，寻呼(paging，P)-RNTI加扰的NPDCCH的重复次数。通过寻呼密度和DRX周期的大小可以确定PO位置，PO位置为NPDCCH资源5的起始位置。
可选的，这里的第四SIB例如可以是SIB2。

S1303、网络设备向第二设备发送承载在NPDCCH资源5上的DCI5，该DCI5用于调度寻呼消息。相应的，第二设备接收来自网络设备的承载在NPDCCH资源5上的DCI5。
需要说明的是，虽然未示出，本申请实施例中，第一设备也可以在NPDCCH资源5上用P-RNTI解扰调度寻呼消息的DCI5，获得寻呼消息的调度信息，如寻呼消息的重复次数，在此统一说明，以下不再赘述。
此外，需要说明的是，本申请实施例中的第一P-RNTI也可以称之为第一无线网络临时标识，即第一设备使用第一无线网络临时标识解析调度寻呼消息的DCI5。其中，该第一无线网络临时标识为第一远端终端设备解析调调度寻呼消息的DCI5的无线网络标识，也就是说，第一远端终端设备会用第一P-RNTI解扰调度寻呼消息的DCI5，在此统一说明，以下不再赘述。
S1304、第二设备在NPDCCH资源5位置上对DCI5进行放大，并将信号放大之后的DCI5发送给第一远端终端设备。相应的，第一远端终端设备接收来自第二设备的放大后的DCI5。

S1312、第二设备根据控制信令34，在传输寻呼消息的时域资源位置的结束位置或者结束位置之后关闭信号放大功能。
需要说明的是，网络设备当不需要寻呼远端终端设备时，在NPDCCH资源5位置上不发送DCI5，此时，第一设备仍需放大NPDCCH资源5所在的资源。也就是说，上述S1301到S1312中的流程中仅包括S1301、S1302、S1305和S1306，在此统一说明，以下不再赘述。
可选的，本申请实施例中，若多个信号的时域资源位置存在重叠(包括部分重叠或全部重叠)，则第二设备应该在接收到针对第一个信号的指示开启信号放大功能的控制信令之后开启信号放大功能，在接收到针对最后一个信号的指示关闭信号放大功能的控制信令之后关闭信号放大功能。其中，这里的第一个信号为时域资源位置的起始位置最靠前的某个信号，这里的最后一个信号为时域资源位置的结束位置最靠后的某个信号。示例性的，如图14所示，假设信号a对应的时域资源位置的起始时刻为时刻1、结束时刻为时刻4；信号b对应的时域资源位置的起始时刻为时刻2、结束时刻为时刻7；信号c对应的时域资源位置的起始时刻为时刻3、结束时刻为时刻5；信号d对应的时域资源位置的起始时刻为时刻6、结束时刻为时刻8；信号e对应的时域资源位置的起始时刻为时刻9、结束时刻为时刻10。其中，时刻排序为时刻1≤时刻2≤时刻3≤时刻4≤时刻5≤时刻6≤时刻7≤时刻8≤时刻9≤时刻10，则第二设备应该在接收到针对信号a的指示开启信号放大功能的控制信令之后开启信号放大功能(即在时刻1或时刻1之前开启信号放大功能)，第二设备应该在接收到针对信号d的指示关闭信号放大功能的控制信令之后关闭信号放大功能(即在时刻8或时刻8之后关闭信号放大功能)，在此统一说明，以下不再赘述。

或者，可选的，本申请实施例中，也可以是第一设备在确定传输各个信号的时域资源位置之后，维护一个如表二所示的关系列表，进而第一设备针对第一个信号向第二设备发送指示开启信号放大功能的控制信令，针对最后一个信号向第二设备发送指示关闭信号放大功能的控制信令。其中，这里的第一个信号为时域资源位置的起始位置最靠前的某个信号，这里的最后一个信号为时域资源位置的结束位置最靠后的某个信号。比如，如图14所示，则第一设备在确定传输信号a的时域资源位置之后，在该时域资源位置的起始位置或起始位置之前(即在时刻1或时刻1之前)向第二设备发送指示开启信号放大功能的控制信令；第一设备在确定传输信号d的时域资源位置之后，在该时域资源位置的结束位置或结束位置之后(即在时刻8或时刻8之后)向第二设备发送指示关闭信号放大功能的控制信令，这样可以保证信号放大功能在时刻1至时刻8之间一直处于开启状态。
可选的，本申请实施例中的第一设备在开机接入到网络后处于长连接态，即一直处于连接态。当网络设备有系统消息变更时，网络设备直接指示一条RRC消息通知第一设备有系统消息变更，这条RRC消息可以是一条新的RRC消息，第一设备在接收到该RRC消息后，就知道系统消息变更了，进而可以重新确定寻呼、随机接入和参考信号等资源位置，在此统一说明，以下不再赘述。
可选的，本申请实施例中，第一设备可以通过RRC消息告诉网络设备自己的C-RNTI，该RRC消息中带有第一设备的C-RNTI，网络设备在知道第一设备的C-RNTI的情况下，可以与第一设备进行通信，如通过RRC消息指示第一设备系统消息变更，在此统一说明，以下不再赘述。
需要说明的是，本申请上述实施例以第一设备分别向第二设备发送指示开启信号放大功能的控制信令和关闭信号放大功能的控制信令为例进行说明。当然，本申请实施例中，也可以是第一设备在指示第二设备开启信号放大功能时同时指示信号放大功能开启的持续时间或者关闭信号放大功能的时间，以使得第二设备在开启信号放大功能之后，在需要关闭信号放大功能的时间关闭信号放大功能，本申请实施例对此不做具体限定。
需要说明的是，本申请上述实施例中的NPSS处理流程、NSS处理流程、MIB处理流程、SIB1处理流程、其他SIB处理流程、随机接入流程、上行或下行数据的调度流程以及寻呼流程相互解耦，互不依赖。比如，上述随机接入流程之前的寻呼流程也可以是其它寻呼流程，或者上述寻呼流程之后的随机接入流程也可以是其它随机接入 流程，等等，本申请实施例对此不作具体限定。
通常，repeater一直处于开启的状态，不论是有用信号还是噪声，repeater都会对其进行放大。当DeNB没有发送数据给远端终端设备时，放大的噪声会对DeNB和其他终端设备产生噪声干扰。基于本申请实施例图10或图11或图12或图13所示的信号处理方法，由于第一设备可以在传输第一信号的第一时域资源位置的起始位置或者起始位置之前指示第二设备开启信号放大功能，也就是说当有信号需要中转时才进行信号放大，当没有信号需要中转时不需要开启信号放大功能，因此可以避免当DeNB没有发送数据给远端终端设备时，放大的噪声会对DeNB和其他终端设备产生噪声干扰的问题，从而可以降低噪声干扰。

需要说明的是，本申请实施例中的消息6也可以理解为承载在NPDSCH上的下行数据，在此统一说明，以下不再赘述。
至此，下行数据的调度流程结束。
可选的，本申请实施例中，上述描述的随机接入过程、下行数据处理过程以及上行数据处理过程都是针对网络设备和一个远端终端设备进行描述的。实际上，网络设备可能与多个远端终端设备交互。该情况下，第三设备可以预先存储无线网络临时标 识与USS或者CSS的映射关系，该映射关系中包括上述第一无线网络临时标识与第一USS或者第一CSS的映射关系。这里的第一无线网络临时标识可以为上述第一C-RNTI、第一RA-RNTI或者第一TC-RNTI。其中，第三设备确定第一无线网络临时标识的方式可参考上述实施例中第一设备确定第一无线网络临时标识的方式，在此不再赘述。
可选的，本申请实施例中，第三设备预先存储的第一无线网络临时标识与第一USS或者第一CSS的映射关系的获取方式可参考上述实施例中第一设备预先存储的第一无线网络临时标识与第一USS或者第一CSS的映射关系的获取方式，在此不再赘述。
可选的，本申请实施例中，当第一远端终端设备处于空闲态时，第一远端终端设备可以在PO位置为起始子帧的物理下行控制信道搜索空间内以盲检的形式检测物理下行控制信道，该过程称之为寻呼流程。在寻呼成功之后即可进入上述随机接入流程。下面给出该寻呼流程中的信号处理方法，如图18所示，包括如下步骤：
S1801、第三设备根据第四SIB中包括的NPDCCH资源5的时域位置指示信息，在NPDCCH资源5的起始时域位置或起始时域位置之前开启信号放大功能。
其中，本申请实施例中，NPDCCH资源5的时域位置指示信息具体可以是DRX周期的大小，寻呼密度(即一个DRX周期中包括的寻呼机会的个数)，P-RNTI加扰的NPDCCH的重复次数。通过寻呼密度和DRX周期的大小可以确定PO位置，PO位置为NPDCCH资源5的起始位置。
可选的，这里的第四SIB例如可以是SIB2。
S1802、网络设备向第三设备发送承载在NPDCCH资源5上的DCI5，该DCI5用于调度寻呼消息。相应的，第三设备接收来自网络设备的承载在NPDCCH资源5上的DCI5。
可选的，本申请实施例中，第三设备也可以在NPDCCH资源5上用P-RNTI解扰调度寻呼消息的DCI5，获得寻呼消息的调度信息，如寻呼消息的重复次数，在此统一说明，以下不再赘述。
此外，需要说明的是，本申请实施例中的第一P-RNTI也可以称之为第一无线网络临时标识，即第三设备使用第一无线网络临时标识解析调度寻呼消息的DCI5。其中，该第一无线网络临时标识为第一远端终端设备解析调调度寻呼消息的DCI5的无线网络标识，也就是说，第一远端终端设备会用第一P-RNTI解扰调度寻呼消息的DCI5，在此统一说明，以下不再赘述。
S1803、第三设备在NPDCCH资源5位置上对DCI5进行放大，并将信号放大之后的DCI5发送给第一远端终端设备。相应的，第一远端终端设备接收来自第三设备的放大后的DCI5。
S1804、第三设备在NPDCCH资源5的结束时域位置或结束时域位置之后关闭信号放大功能。
S1805、第三设备根据获取到的寻呼消息的调度信息，在传输寻呼消息的时域资源位置的起始位置或者起始位置之前开启信号放大功能。
S1806、网络设备向第三设备发送寻呼消息。相应的，第三设备接收来自网络设备的寻呼消息。
S1807、第三设备在传输寻呼消息的时域资源位置对寻呼消息进行放大，并将信号 放大之后的寻呼消息发送给第一远端终端设备。相应的，第一远端终端设备接收来自第三设备的放大后的寻呼消息。
S1808、第三设备在传输寻呼消息的时域资源位置的结束位置或者结束位置之后关闭信号放大功能。
需要说明的是，网络设备当不需要寻呼远端终端设备时，在NPDCCH资源5位置上不发送DCI5，此时，第三设备仍需放大NPDCCH资源5所在的资源。也就是说，上述S1801到S1808中的流程中仅包括S1801和S1804，在此统一说明，以下不再赘述。
可选的，本申请实施例中，若多个信号的时域资源位置存在重叠(包括部分重叠或全部重叠)，则第三设备应该在传输第一个信号的时频资源位置的起始位置或起始位置之前开启信号放大功能，在传输最后一个信号的时频资源位置的结束位置或结束位置之前关闭信号放大功能。其中，这里的第一个信号为时域资源位置的起始位置最靠前的某个信号，这里的最后一个信号为时域资源位置的结束位置最靠后的某个信号。示例性的，如图14所示，假设信号a对应的时域资源位置的起始时刻为时刻1、结束时刻为时刻4；信号b对应的时域资源位置的起始时刻为时刻2、结束时刻为时刻7；信号c对应的时域资源位置的起始时刻为时刻3、结束时刻为时刻5；信号d对应的时域资源位置的起始时刻为时刻6、结束时刻为时刻8；信号e对应的时域资源位置的起始时刻为时刻9、结束时刻为时刻10。其中，时刻排序为时刻1≤时刻2≤时刻3≤时刻4≤时刻5≤时刻6≤时刻7≤时刻8≤时刻9≤时刻10，则第三设备应该在传输信号a的时频资源位置的起始位置或起始位置之前开启信号放大功能(即在时刻1或时刻1之前开启信号放大功能)，在传输信号d的时频资源位置的结束位置或结束位置之前关闭信号放大功能(即在时刻8或时刻8之后关闭信号放大功能)，在此统一说明，以下不再赘述。
要实现上述功能，一种可能的实现方式中，第三设备在确定传输各个信号的时域资源位置之后，维护一个如表三所示的关系列表，包括：信号以及对应的信号放大功能的开启时刻和关闭时刻的映射关系，从而第三设备根据该映射关系，可以获知传输不同信号的时域位置之间是否存在重叠，以及在存在重叠的情况下，第一个信号对应的信号放大功能的开启时刻以及最后一个信号对应的信号放大功能的关闭时刻。

可选的，本申请实施例中的第三设备在开机接入到网络后处于长连接态，即一直处于连接态。当网络设备有系统消息变更时，网络设备直接指示一条RRC消息通知第 三设备有系统消息变更，这条RRC消息可以是一条新的RRC消息，第三设备在接收到该RRC消息后，就知道系统消息变更了，进而可以重新确定寻呼、随机接入和参考信号等资源位置，在此统一说明，以下不再赘述。
可选的，本申请实施例中，第三设备可以通过RRC消息告诉网络设备自己的C-RNTI，该RRC消息中带有第三设备的C-RNTI，网络设备在知道第三设备的C-RNTI的情况下，可以与第三设备进行通信，如通过RRC消息指示第三设备系统消息变更，在此统一说明，以下不再赘述。
需要说明的是，本申请上述实施例中的NPSS处理流程、NSS处理流程、MIB处理流程、SIB1处理流程、其他SIB处理流程、随机接入流程、上行或下行数据的调度流程以及寻呼流程相互解耦，互不依赖。比如，上述随机接入流程之前的寻呼流程也可以是其它寻呼流程，或者上述寻呼流程之后的随机接入流程也可以是其它随机接入流程，等等，本申请实施例对此不作具体限定。
通常repeater一直处于开启的状态，不论是有用信号还是噪声，repeater都会对其进行放大。当DeNB没有发送数据给远端终端设备时，放大的噪声会对DeNB和其他终端设备产生噪声干扰。基于本申请实施例图15或图16或图17或图18所示的信号处理方法，由于第三设备可以确定传输第一信号的第一时域资源位置，并在第一时域资源位置的起始位置或起始位置之前开启第三设备的信号放大功能，也就是说当有信号需要中转时才进行信号放大，当没有信号需要中转时不需要开启信号放大功能，因此可以避免当DeNB没有发送数据给远端终端设备时，放大的噪声会对DeNB和其他终端设备产生噪声干扰的问题，从而可以降低噪声干扰。
上述图15至图18各步骤中的第三设备的动作可以由图6所示的通信设备600中的处理器601调用存储器603中存储的应用程序代码来执行，本申请实施例对此不作任何限制。
