随机接入过程的控制方法和相关设备
相关申请的交叉引用
本申请基于申请号为202210468455.0、申请日为2022年04月29日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域

背景技术
相关技术中，通过部署可重构智能超表面(Reconfigurable Intelligent Surface，RIS)或智能中继器(Smart Repeater)的方式来增加小区覆盖。对于网络设备来说，在随机接入过程中，如果能够识别终端的接入方式是直接接入还是经RIS/Smart Repeater中继接入，那么就可以制定个性化的策略，并且有利于RIS/Smart Repeater的地理位置部署。当前协议框架下可以通过区分接入的同步信号和PBCH块(Synchronization Signal and PBCH block，SSB)波束来粗略估计终端的位置，但方法准确度较低，并且由于频率范围二(FR2)的波束覆盖范围比较大，同一个接收波束下可能存在直接接入的终端与通过RIS/Smart Repeater中继接入的终端，因此很难实现准确地在接入阶段进行识别终端的类型。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
应了解，在本申请实施例的描述中，如果有描述到“第一”、“第二”等只是用于区分技术特征为目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量或者隐含指明所指示的技术特征的先后关系。“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示单独存在A、同时存在A和B、单独存在B的情况。其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项”及其类似表达，是指的这些项中的任意组，包括单项或复数项的任意组。例如，a、b和c中的至少一项可以表示：a，b，c，a和b，a和c，b和c，或者，a和b和c，其中a，b，c可以是单个，也可以是多个。
此外，下面所描述的本申请各个实施方式中所涉及到的技术特征只要彼此之间未构成冲突就可以相互组合。
高频通信的一个主要问题是信号能量随传输距离增加而急剧衰减，导致信号传输距离短，影响小区的信号覆盖。为增加小区的信号覆盖范围，相关技术提出，在网络设备和终端之间增加可重构智能超表面(Reconfigurable Intelligent Surface，RIS)或智能中继器(Smart Repeater)的方式来增加小区覆盖。
如图1所示，为本申请实施例适用的一种通信系统的示意图。在图1所示的通信系统中， 包括网络设备10、信号调节装置20和多个终端(31、41、42)。其中，终端可以分成两类：第一类，是位于网络设备的直接覆盖范围内，直接接入网路设备的终端，如图1中的终端31；第二类，是位于网络设备的直接覆盖范围以外，通过信号调节装置接入网路设备的终端，如图1中的终端41、42，也就是说网络设备10和终端41、42之间的信息需要经过信号调节装置20进行中继才能到达。这里的信号调节装置20可理解为是RIS或者Smart Repeater。
可以理解的是，本申请实施例涉及的网络设备可以为无线接入网中的节点，又可以称为基站，还可以称为无线接入网(Radio Access Network，RAN)节点(或设备)。例如，网络设备可以包括长期演进(Long Term Evolution，LTE)系统或演进的LTE系统(LTE-Advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，如传统的宏基站eNB和异构网络场景下的微基站eNB；或者也可以包括5G新无线(new radio，NR)系统中的下一代节点B(Next generation node B，gNB)，或者还可以包括传输接收点(Transmission Reception Point，TRP)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(Base Band Unit，BBU)、基带池BBU pool，或WiFi接入点(Access Point，AP)等；再或者还可以包括云接入网(Cloud Radio Access Network，CloudRAN)系统中的集中式单元(Centralized Unit，CU)和分布式单元(Distributed Unit，DU)；又或者可以包括非陆地网络(Non-Terrestrial Network，NTN)中的基站，即可以部署于高空平台或者卫星，在NTN中，网络设备可以作为层1(L1)中继(Relay)，或者可以作为基站，或者可以作为DU，或者可以作为接入回传一体化(integrated access and backhual，IAB)节点；又或者，网络设备可以是IoT中实现基站功能的设备，例如车联网(Vehicle-to-everything，V2X)、设备到设备(Device to Device，D2D)、或者机器到机器(Machine to Machine，M2M)中实现基站功能的设备，本申请实施例并不限定。
可以理解的是，本申请实施例涉及的终端可以指用户设备、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。终端还可以是蜂窝电话、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、计算设备或连接收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通信网络中的终端设备等，本申请实施例对此并不限定。
可以理解的是，本申请实施例涉及的智能超表面(RIS)，是一种具有可编程电磁特性的人工电磁表面结构，其面板上包含大量按照矩阵方式排布的电磁单元，通过控制电路可以动态地调控电磁单元的电磁性质，实现三维空间内无线信号传播特性的智能化重构，可以突破传统无线环境被动适应的局限性。
可以理解的是，本申请实施例涉及的智能中继器(Smart Repeater)，可以认为是部署在网络节点和终端设备之间的一个信号的中继装置，用于增强链路的性能。在下行，接收来自于网络节点的信息，将其进行增强放大之后，再发送给终端设备；对于上行也类似。
需说明的是，为方便起见，在本申请实施例的一些描述中，会使用“基站”指代网络设备，使用“RIS”或者“Smart Repeater”指代信号调节装置，使用“UE”或者“用户”指代终端。
为方便理解本申请的技术方案，下面对终端与网络设备建立连接的随机接入过程进行简 单的介绍。
随机接入过程是指从用户发送随机接入前导码开始尝试接入网络到与网络间建立起基本的信令连接之前的过程。随机接入是移动通信系统中非常关键的步骤，也是终端设备与网络建立通信链路的最后一步。终端设备可以通过随机接入与网络设备进行信息交互。根据用户是否独占前导码资源，可将用户的随机接入方式划分为基于竞争的随机接入(Contenti on-based Random Access)以及基于非竞争的随机接入(Contention-free Random Access)。
竞争的随机接入过程主要包括如下四步：第一步，终端从前导码资源池中随机选择一个前导码(preamble)，通过第一消息Msg1向网络设备发送随机接入请求，包含随机接入前导码；第二步，网络设备通过第二消息Msg2向终端发送随机接入响应(Random Access Response，RAR)，包含随机接入前导码标识符、临时小区无线网络临时标识(Cell-Radio Network Temporary Identifier，CRNTI)等信息，以及为终端下次上行传输所分配的时频资源；第三步，终端通过第三消息Msg3向网络设备发送无线资源控制(Radio Resource Control，RRC)连接请求，Msg3中包含用户终端标识以及RRC链接请求等信息，其中，该用户终端标识是用户唯一的，用于解决冲突；第四步，网络设备向终端发送第四消息Msg4(此过程也即为竞争解决content ion resolution过程)，Msg4包含了冲突解决中胜出的用户终端标识。用户在检测出自己的标识后，将临时C-RNTI升级为C-RNTI，并向基站发送ACK信号，完成随机接入过程，并等待基站的调度。否则，用户将在一段延时后开始新的随机接入过程。
非竞争的随机接入过程主要包括如下两步：第一步，终端通过A消息MsgA(随机接入请求)向网络设备发送已分配好的随机接入前导码；第二步，网络设备检测到分配好的随机接入前导码后，通过B消息MsgB(随机接入响应RAR(Random Access Response))向终端发送定时提前以及上行资源分配等信息。用户接收到随机接入响应后，认为已完成上行同步，等待基站的进一步调度。因此，基于非竞争的随机接入过程仅包含两个步骤：步骤一为发送前导序列；步骤二为随机接入响应的发送。
应能理解，如果终端是经RIS/Smart Repeater接入网络设备的，那么上述随机接入过程中终端和网络设备之间的交互信息均需通过RIS/Smart Repeater中继才能实现。
对于网络设备来说，在随机接入过程中，如果能够识别终端的接入方式是直接接入还是经RIS/Smart Repeater中继接入，那么就可以制定个性化的策略，并且有利于RIS/Smart Repeater的地理位置部署。当前协议框架下可以通过区分接入的SSB波束来粗略估计终端的位置，但方法准确度较低，并且由于FR2的波束覆盖范围比较大，同一个接收波束下可能存在直接接入的终端与通过RIS/Smart Repeater中继接入的终端，因此很难准确地在接入阶段识别终端的类型。
为解决上述技术问题，本申请实施例提供了一种随机接入过程的控制方法、网络设备、信号调节装置、终端、计算机可读存储介质和计算机程序产品，用于实现在接入阶段中识别终端类型。
如图2所示，为本申请实施例提供的一种随机接入过程的控制方法的流程图，该方法应用于网络设备侧，包括如下步骤S110-S130，下面依次对各个步骤进行介绍：
步骤S110，向终端下发第一配置信息，第一配置信息用于指示终端在接收到随机接入响应消息后重复发送多个上行信号。
本申请实施例中，网络设备向终端下发第一配置信息，目的是使终端在向网络设备发起 随机接入请求，并接收到网络设备的随机接入响应之后，根据该第一配置信息，向网络设备重复发送多个上行信号。
作为一种示例，如果终端向网络设备发起的是竞争随机接入请求，那么，终端向网络设备重复发送多个上行信号，可以是向网络设备重复发送多个随机接入过程中的第三消息(Msg3)。
作为另一种示例，终端向网络设备重复发送多个上行信号，还可以是向网络设备重复发送多个物理上行共享信道(Physical Uplink Shared Channel，PUSCH)。终端接收到网络设备分配的上行资源后，则可根据所分配的上行资源重复地向网络设备发送PUSCH。
应能理解，终端重复发送的上行信号还可以是其他类型的信号，本申请实施例对此不作限制。
本申请实施例的第一配置信息包括以下信息中的至少一项：重复发送的时域起始位置，重复发送的时域间隔，重复发送的信号数目。其中，重复发送的时域起始位置指示重复发送的多个上行信号中的第一个上行信号的时域位置，具体可以是一个单位为时隙或者符号的偏移间隔，即在随机接入响应消息的接收时刻经过上述偏移间隔后开始进行上行信号的重复发送；重复发送的时域间隔指示重复发送的上行信号的发送时域间隔，即两次重复发送的信号时域间隔，单位可以是时隙、符号等；重复发送的信号数目指示重复发送的上行信号的重复发送次数，例如重复发送4次，即重复发送的信号数目为4。当然，第一配置信息可以包含比上述更多或者更少的信息，例如，第一配置信息可以不指示重复发送的时域起始位置，而终端采用默认的偏移间隔确定重复发送的时域起始位置；第一配置信息也可以不指示重复发送的时域间隔，终端采用默认的时域间隔进行重复发送；第一配置信息还可以不指示重复发送的信号数目，而终端采用默认的重复发送信号数目进行重复发送。
示例性的，网络设备可以通过以下几种方式将第一配置信息下发给终端：
第一种，网络设备通过随机接入信道(Random Access Channel，RACH)配置信息下发给终端，该RACH配置信息包含携带第一配置信息的信元。其中，RACH配置信息可以是RACH-Config Common信息，或者RACH-Config Dedicated信令，还可以是RACH-Config Generic信令。
可以理解的是，以RACH配置信息是RACH-Config Common信息为例，为了第一配置信息承载于RACH-Config Common中，可以在RACH-Config Common的信元(IE)中添加与第一配置信息相关的字段。如图3所示，为RACH-Config Common信息的格式示意图，其中，与第一配置信息相关的字段包括K2-offset-repetition、repetition-Number-Msg3。这里，K2-offset-repetition指代重复发送的时域间隔；repetition-Number-Msg3指代重复发送的信号数目。
第二种，网络设备通过随机接入响应消息下发给终端，第一配置信息携带在随机接入响应消息中。
可以理解的是，网络设备可以通过随机接入过程中的RAR消息将第一配置信息下发给终端，也就是说，令第一配置信息承载于随机接入过程中的RAR消息中。这里的RAR消息具体可以是随机接入过程(包括竞争或者非竞争随机接入方式)中的第二条消息。具体地，可以在RAR消息添加与第一配置信息相关的字段，例如：k2+j(指代重复发送的时域起始位置)，K2-offset-repetition(指代重复发送的时域间隔)，repetition-Number-Msg3(指代重复 发送的信号数目)。
步骤S120，向信号调节装置下发第二配置信息，第二配置信息用于指示信号调节装置通过不同的预设方式中继第一上行信号和第二上行信号。
本申请实施例中，终端向网络设备发起随机接入请求，网络设备向终端发送随机接入响应，终端收到随机接入响应后，根据预置的第一配置信息向网络设备重复发送多个上行信号。
终端重复发送的多个上行信号中包括第一上行信号和第二上行信号。具体而言，第一上行信号和第二上行信号是终端重复发送的多个上行信号中不同的信号。第一上行信号可以包括一个或者多个信号，第二上行信号也可以包括一个或者多个信号。
在一个示例中，第一上行信号表征终端重复发送的多个上行信号中的第奇数个上行信号；第二上行信号表征终端重复发送的多个上行信号中的第偶数个上行信号。例如，终端在接收到网络设备侧的随机接入响应后，重复发送了4个上行信号，其中，第1个、第3个信号属于第一上行信号，第2个、第4个信号属于第二上行信号。
第一上行信号、第二上行信号也可以表征终端重复发送的多个上行信号中的特定一个或多个信号。例如，终端在接收到网络设备侧的随机接入响应后，重复发送了4个上行信号，第一上行信号特指第1个、第2个信号，第二上行信号特指第3个、第4个信号。
本申请实施例中，网络设备向信号调节装置下发第二配置信息，目的是使信号调节装置在接收到来自于终端的多个重复发送的上行信号之后，对这些上行信号中的第一上行信号和第二上行信号采用不同方式进行中继。一般而言，采用不同方式中继的信号在网络设备侧会具有较大的差别性；而终端直接重复发送给网络设备的多个上行信号没有经过特殊处理，所以在网络设备侧不会具有较大的差别性。这样，网络设备就可以根据接收到的重复发送的上行信号是否具有较大差别性，来确定这些上行信号是经信号调节装置中继而来，还是由终端直接发送。
示例性的，第二配置信息包括以下信息中的至少一项：重复发送的时域起始位置，重复发送的时域间隔，重复发送的信号数目，变更码本信息，变更相位信息，停止中继指示信息。
其中，重复发送的时域起始位置指示终端重复发送的多个上行信号中的第一个上行信号的时域位置，信号调节装置可以根据该时域起始位置确定上行信号接收的起始位置。
重复发送的时域间隔指示重复发送的多个上行信号的时域间隔，信号调节装置可以根据该时域间隔对接收终端重复发送的上行信号。
重复发送的信号数目指示终端重复发送的上行信号的数目，信号调节装置可以根据该数目接收对应数量的上行信号。
变更码本信息使信号调节装置具体可以是码本索引，使信号调节装置根据码本索引获取到第二码本。可以理解，第二码本是与第一码本不相同的码本，第一码本指信号调节装置原来用于中继当前终端信号的码本。
变更相位信息用于使信号调节装置对第一码本进行相位变更，得到第三码本。
停止中继指示信息用于使信号调节装置对终端重复发送的部分上行信号采用停止中继的策略进行中继。
应能理解的是，第二配置信息可以包括重复发送的时域起始位置，重复发送的时域间隔，重复发送的信号数目，变更码本信息，变更相位信息，停止中继指示信息中的一项或者多项，本申请实施例对第二配置信息的具体内容不作限制。
示例性的，信号调节装置通过不同的预设方式中继第一上行信号和第二上行信号，可以包括以下几种实现方式：
第一种，信号调节装置通过第一码本对第一上行信号进行中继，通过第二码本对第二上行信号进行中继。
可以理解的是，如果第二配置信息中包含变更码本信息，那么信号调节装置可以根据变更码本信息获取第二码本。对于终端重复发送的上行信号，信号调节装置对其中的第一上行信号采用第一码本进行中继，对其中的第二上行信号采用第二码本进行中继，如此达到对第一上行信号和第二上行信号的中继方式不一样。
第二种，通过第一码本对第一上行信号进行中继，通过对第一码本变更相位后获得的第三码本对第二上行信号进行中继。
可以理解的是，如果第二配置信息中包含变更相位信息，那么信号调节装置可以根据变更相位信息对第一码本进行相位变更，得到第三码本。对于终端重复发送的上行信号，信号调节装置对其中的第一上行信号采用第一码本进行中继，对其中的第二上行信号采用第三码本进行中继，如此达到对第一上行信号和第二上行信号的中继方式不一样。
第三种，通过第一码本对第一上行信号进行中继，通过停止中继的策略对第二上行信号进行中继。
可以理解的是，如果第二配置信息中包含停止中继指示信息，那么对于终端重复发送的上行信号，信号调节装置可以对其中的第一上行信号采用第一码本进行中继，对其中的第二上行信号采用停止中继的策略进行中继，具体地，可以在中继第二上行信号时关闭面板，达到停止中继目的。
示例性的，第二配置信息通过以下任一种方式下发给信号调节装置：
第一种，在与信号调节装置建立连接时，将第二配置信息下发给信号调节装置。
可以理解的是，网络设备可以通过半静态方式，在添加RIS或者Smart Repeater时，将第二配置信息作为现有通信内容的一部分下发，当有终端需要下发随机接入响应时，通过新的参考信号、数据包等方式将第二配置信息激活信令通知给RIS/Smart Repeater。
第二种，在下发随机接入响应消息时，将第二配置信息下发给信号调节装置。
可以理解的是，网络设备可以通过动态方式，当有终端需要下发随机接入响应时，将第二配置信息以新的参考信号、数据包等方式下发给RIS/Smart Repeater，并直接激活。
步骤S130，当接收到终端根据随机接入响应消息重复发送的多个上行信号，则根据上行信号接收情况确定终端的类型。
本申请实施例描述的终端的类型包括第一类型和第二类型，其中，第一类型表征终端直接接入网络设备，第二类型表征终端通过信号调节装置接入网络设备。
本申请实施例中，根据上行信号接收情况确定终端的类型，具体可以根据接收到的多个上行信号的信号质量信息确定终端的类型。
示例性的，信号质量信息可以包括参考信号接收功率(Reference Signal Receiving Power，RSRP)、信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)、信道质量指示(Channel Quality Indicator，CQI)、参考信号接收质量(Reference Signal Received Quality，RSRQ)等信息。
示例性的，如图4所示，根据接收到的多个上行信号的信号质量信息确定终端的类型， 具体包括但不限于如下步骤S131-S133：
步骤S131，获取接收到的多个上行信号中的第一上行信号的第一信号质量信息；
步骤S132，获取接收到的多个上行信号中的第二上行信号的第二信号质量信息；
步骤S133，判断第一信号质量信息和第二信号质量信息的差距值是否小于或者等于预设的差距阈值，若是，确定终端的类型为第一类型；若否，确定终端的类型为第二类型。
本申请实施例，通过比较第一上行信号和第二上行信号的信号质量信息，判断当前接收到的多个重复的上行信号是由第一类型还是第二类型的终端发送。可以理解的是，如果由第一类型的终端发送，那么，网络设备侧接收到的第一上行信号和第二上行信号的信号质量不会相差很大；如果由第二类型的终端发送，由于第二类型的终端的信号需要经过信号调节装置，而信号调节装置采用不同的方式中继第一上行信号和第二上行信号，使得网络设备侧接收到的第一上行信号和第二上行信号的信号质量相差较大。
举例来说，在RIS关闭面板的情况下，网络设备接收到的第二类型终端发出的第二上行信号的RSRP和SINR均很小，与RIS打开面板的情况下收到的第二类型终端发出的第一上行信号的RSRP和SINR相差较大。本申请实施例基于此，通过设置一个合理的差距阈值，判断第一上行信号对应的第一信号质量信息和第二上行信号对应的第二信号质量信息的差距值是否大于差距阈值，进而确定终端属于第一类型还是第二类型。
可以理解的是，为了提高终端类型识别的准确性，可以结合多种信号质量信息作为判断因素。示例性，第一信号质量信息包括第一RSRP和第一SINR，第二信号质量信息包括第二RSRP和第二SINR，差距阈值包括RSRP差距阈值和SINR差距阈值；当第一信号质量信息和第二信号质量信息的差距值大于预设的差距阈值，确定终端的类型为第二类型，包括：当第一RSRP和第二RSRP的差距值大于预设的RSRP差距阈值、且第一SINR和第二SINR的差距值大于预设的SINR差距阈值，确定终端的类型为第二类型。
可以理解，在第一上行信号和第二上行信号分别有多个的情况下，可以对多个第一上行信号对应的信号质量信息求平均，得到第一信号质量信息；对多个第二上行信号对应的信号质量信息求平均，得到第二信号质量信息。
示例性的，在第一上行信号和第二上行信号分别有多个的情况下，第一RSRP为多个第一上行信号对应的RSRP的平均值，第一SINR为多个第一上行信号对应的SINR的平均值，第二RSRP为多个第二上行信号对应的RSRP的平均值，第二SINR为多个第二上行信号对应的SINR的平均值。
如图5所示，为本申请实施例提供的一种随机接入过程的控制方法的流程图，该方法应用于信号调节装置侧，包括如下步骤S210-S220，下面依次对各个步骤进行介绍：
步骤S210，当接收到终端根据随机接入响应消息重复发送的多个上行信号，获取网络设备下发的第二配置信息。
步骤S220，根据第二配置信息将多个上行信号中继给网络设备，多个上行信号包括第一上行信号和第二上行信号，且第一上行信号和第二上行信号通过不同的预设方式中继，使得网络设备根据上行信号接收情况确定终端的类型。
本申请实施例中，信号调节装置在接收到网络设备下发的第二配置信息之后，如果接收到来自于终端的多个重复发送的上行信号，则根据第二配置信息对这些上行信号中的第一上行信号和第二上行信号采用不同方式进行中继。
具体地，终端向网络设备发起随机接入请求，网络设备向终端发送随机接入响应，终端收到随机接入响应后，根据预置的第一配置信息向网络设备重复发送多个上行信号。上行信号包括随机接入过程中终端发送的第三消息或者PUSCH。
可以理解的是，第一上行信号和第二上行信号是终端重复发送的多个上行信号中不同的信号。第一上行信号、第二上行信号可以分别包括一个或者多个信号。
在一个示例中，第一上行信号表征终端重复发送的多个上行信号中的第奇数个上行信号；第二上行信号表征终端重复发送的多个上行信号中的第偶数个上行信号。例如，终端在接收到网络设备侧的随机接入响应后，重复发送了4个上行信号，其中，第1个、第3个信号属于第一上行信号，第2个、第4个信号属于第二上行信号。
第一上行信号、第二上行信号也可以表征终端重复发送的多个上行信号中的特定一个或多个信号。例如，终端在接收到网络设备侧的随机接入响应后，重复发送了4个上行信号，第一上行信号特指第1个、第2个信号，第二上行信号特指第3个、第4个信号。
示例性的，第二配置信息包括以下信息中的至少一项：重复发送的时域起始位置，重复发送的时域间隔，重复发送的信号数目，变更码本信息，变更相位信息，停止中继指示信息。
其中，重复发送的时域起始位置指示终端重复发送的多个上行信号中的第一个上行信号的时域位置，信号调节装置可以根据该时域起始位置确定上行信号接收的起始位置。
重复发送的时域间隔指示重复发送的多个上行信号的时域间隔，信号调节装置可以根据该时域间隔对接收终端重复发送的上行信号。
重复发送的信号数目指示终端重复发送的上行信号的数目，信号调节装置可以根据该数目接收对应数量的上行信号。
变更码本信息使信号调节装置对第一码本进行变更，具体可以是码本索引，使信号调节装置根据码本索引获取到第二码本。可以理解，第二码本是与第一码本不相同的码本，第一码本指信号调节装置原来用于中继当前终端信号的码本。
变更相位信息用于使信号调节装置对第一码本进行相位变更，得到第三码本。
停止中继指示信息用于使信号调节装置对终端重复发送的部分上行信号采用停止中继的策略进行中继。
应能理解的是，第二配置信息可以包括重复发送的时域起始位置，重复发送的时域间隔，重复发送的信号数目，变更码本信息，变更相位信息，停止中继指示信息中的一项或者多项，本申请实施例对第二配置信息的具体内容不作限制。
示例性的，信号调节装置通过不同的预设方式中继第一上行信号和第二上行信号，可以包括以下几种实现方式：
第一种，信号调节装置通过第一码本对第一上行信号进行中继，通过第二码本对第二上行信号进行中继。
可以理解的是，如果第二配置信息中包含变更码本信息，那么信号调节装置可以根据变更码本信息获取第二码本。对于终端重复发送的上行信号，信号调节装置对其中的第一上行信号采用第一码本进行中继，对其中的第二上行信号采用第二码本进行中继，如此达到对第一上行信号和第二上行信号的中继方式不一样。这里的第一码本和第二码本是不相同的码本。
第二种，通过第一码本对第一上行信号进行中继，通过对第一码本变更相位后获得的第三码本对第二上行信号进行中继。
可以理解的是，如果第二配置信息中包含变更相位信息，那么信号调节装置可以根据变更相位信息对第一码本进行相位变更，得到第三码本。对于终端重复发送的上行信号，信号调节装置对其中的第一上行信号采用第一码本进行中继，对其中的第二上行信号采用第三码本进行中继，如此达到对第一上行信号和第二上行信号的中继方式不一样。
第三种，通过第一码本对第一上行信号进行中继，通过停止中继的策略对第二上行信号进行中继。
可以理解的是，如果信号调节装置为RIS，第二配置信息中包含停止中继指示信息，那么对于终端重复发送的上行信号，RIS可以对其中的第一上行信号采用第一码本进行中继，对其中的第二上行信号采用停止中继的策略进行中继，具体地，可以在中继第二上行信号时关闭面板，达到停止中继目的。
示例性的，信号调节装置可以通过以下任一种方式获取网络设备下发的第二配置信息：
第一种，在与网络设备建立连接时，从网络设备接收第二配置信息；
可以理解的是，网络设备可以通过半静态方式，在添加RIS或者Smart Repeater时，将第二配置信息作为现有通信内容的一部分下发。当有终端需要下发随机接入响应时，通过新的参考信号、数据包等方式将第二配置信息激活信令通知给RIS/Smart Repeater，使RIS/Smart Repeater检测终端的重复发送的上行信号。
第二种，在接收到网络设备的随机接入响应消息时，从网络设备接收第二配置信息。
可以理解的是，网络设备可以通过动态方式，当有终端需要下发随机接入响应时，将第二配置信息以新的参考信号、数据包等方式下发给RIS/Smart Repeater，并直接激活。
可以理解的是，信号调节装置从网络设备接收随机接入响应消息，并将随机接入响应消息转发给终端。
上述随机接入响应消息还可以携带第一配置信息，第一配置信息用于指示终端在接收到随机接入响应消息后重复发送多个上行信号。第一配置信息包括以下信息中的至少一项：重复发送的时域起始位置，重复发送的时域间隔，重复发送的信号数目。其中，重复发送的时域起始位置指示重复发送的多个上行信号中的第一个上行信号的时域位置，具体可以是一个单位为时隙或者符号的偏移间隔，即在随机接入响应消息的接收时刻经过上述偏移间隔后开始进行上行信号的重复发送；重复发送的时域间隔指示重复发送的上行信号的发送时域间隔，即两次重复发送的信号时域间隔，单位可以是时隙、符号等；重复发送的信号数目指示重复发送的上行信号的重复发送次数，例如重复发送4次，即重复发送的信号数目为4。
可以理解的是，采用不同方式中继的信号在网络设备侧会具有较大的差别性；而终端直接重复发送给网络设备的多个上行信号没有经过特殊处理，所以在网络设备侧不会具有较大的差别性。这样，网络设备就可以根据接收到的重复发送的上行信号是否具有较大差别性，来确定这些上行信号是经信号调节装置中继而来，还是由终端直接发送。例如，根据接收到的多个上行信号的信号质量信息确定终端的类型。
如图6所示，为本申请实施例提供的一种随机接入过程的控制方法，该方法应用于终端，包括如下步骤S310至步骤S330：
步骤S310，当接收到来自网络设备的随机接入响应消息，获取网络设备下发的第一配置信息。
本申请实施例中，终端向网络设备发起随机接入请求，网络设备向终端发送随机接入响 应，终端收到随机接入响应后，根据预置的第一配置信息向网络设备重复发送多个上行信号。
上行信号包括随机接入过程中的第三消息或者物理上行共享信道PUSCH。
作为一种示例，如果终端向网络设备发起的是竞争随机接入请求，那么，终端向网络设备重复发送多个上行信号，可以是向网络设备重复发送多个随机接入过程中的第三消息(Msg3)。
作为另一种示例，终端向网络设备重复发送多个上行信号，还可以是向网络设备重复发送多个PUSCH。终端接收到网络设备分配的上行资源后，则可根据所分配的上行资源重复地向网络设备发送PUSCH。
应能理解，终端重复发送的上行信号还可以是其他类型的信号，本申请实施例对此不作限制。
本申请实施例的第一配置信息包括以下信息中的至少一项：重复发送的时域起始位置，重复发送的时域间隔，重复发送的信号数目。其中，重复发送的时域起始位置指示重复发送的多个上行信号中的第一个上行信号的时域位置，具体可以是一个单位为时隙或者符号的偏移间隔，即在随机接入响应消息的接收时刻经过上述偏移间隔后开始进行上行信号的重复发送；重复发送的时域间隔指示重复发送的上行信号的发送时域间隔，即两次重复发送的信号时域间隔，单位可以是时隙、符号等；重复发送的信号数目指示重复发送的上行信号的重复发送次数，例如重复发送4次，即重复发送的信号数目为4。当然，第一配置信息可以包含比上述更多或者更少的信息，例如，第一配置信息可以不指示重复发送的时域起始位置，而终端采用默认的偏移间隔确定重复发送的时域起始位置；第一配置信息也可以不指示重复发送的时域间隔，终端采用默认的时域间隔进行重复发送；第一配置信息还可以不指示重复发送的信号数目，而终端采用默认的重复发送信号数目进行重复发送。
可以理解的是，终端可以通过以下任一种方式获取第一配置信息：
第一种，从网络设备发送的随机接入信道RACH配置信息获取第一配置信息，随机接入信道RACH配置信息包含携带第一配置信息的信元。
其中，RACH配置信息可以是RACH-Config Common信息，或者其他层级的信令，本申请实施例不作限制。
以RACH配置信息是RACH-Config Common信息为例，为了第一配置信息承载于RACH-Config Common中，可以在RACH-Config Common的信元(IE)中添加与第一配置信息相关的字段。如图3所示，为RACH-Config Common信息的格式示意图，其中，与第一配置信息相关的字段包括K2-offset-repetition、repetition-Number-Msg3。这里，K2-offset-repetition指代重复发送的时域间隔；repetition-Number-Msg3指代重复发送的信号数目。
第二种，从随机接入响应消息获取第一配置信息，第一配置信息携带在随机接入响应消息中。
可以理解的是，终端可以通过随机接入过程中的RAR消息获取网络设备下发的第一配置信息，也就是说，令第一配置信息承载于随机接入过程中的RAR消息中。这里的RAR消息具体可以是随机接入过程(包括竞争或者非竞争随机接入方式)中的第二条消息。具体地，可以在RAR消息添加与第一配置信息相关的字段，例如：k2+j(指代重复发送的时域起始位置)，K2-offset-repetition(指代重复发送的时域间隔)，repetition-Number-Msg3(指代重复 发送的信号数目)。
本申请实施例描述的终端的类型包括第一类型和第二类型，其中，第一类型表征终端直接接入网络设备，第二类型表征终端通过信号调节装置接入网络设备。如果终端为第一类型的终端，则执行下面步骤S320；如果终端为第二类型的终端，则执行下面步骤S330。
步骤S320，根据第一配置信息重复发送多个上行信号给网络设备，使得网络设备根据上行信号接收情况确定终端的类型。
对于第一类型的终端，其直接将上行信号发送给网络设备，过程中不会对任一上行信号作特殊的处理。
步骤S330，根据第一配置信息重复发送多个上行信号给信号调节装置，通过信号调节装置将多个上行信号中继给网络设备，使得网络设备根据上行信号接收情况确定终端的类型，其中，多个上行信号包括第一上行信号和第二上行信号，第一上行信号和第二上行信号由信号调节装置通过不同的预设方式进行中继。
本申请实施例中，终端重复发送的多个上行信号中包括第一上行信号和第二上行信号。具体而言，第一上行信号和第二上行信号是终端重复发送的多个上行信号中不同的信号。第一上行信号可以包括一个或者多个信号，第二上行信号也可以包括一个或者多个信号。
在一个示例中，第一上行信号表征终端重复发送的多个上行信号中的第奇数个上行信号；第二上行信号表征终端重复发送的多个上行信号中的第偶数个上行信号。例如，终端在接收到网络设备侧的随机接入响应后，重复发送了4个上行信号，其中，第1个、第3个信号属于第一上行信号，第2个、第4个信号属于第二上行信号。
第一上行信号、第二上行信号也可以表征终端重复发送的多个上行信号中的特定一个或多个信号。例如，终端在接收到网络设备侧的随机接入响应后，重复发送了4个上行信号，第一上行信号特指第1个、第2个信号，第二上行信号特指第3个、第4个信号。
可以理解的是，第二类型的终端将上行信号重复发送给信号调节装置，对于其中的第一上行信号和第二上行信号，信号调节装置会通过不同的预设方式中继，具体包括以下几种方式：
第一种，信号调节装置通过第一码本对第一上行信号进行中继，通过第二码本对第二上行信号进行中继。
可以理解的是，如果第二配置信息中包含变更码本信息，那么信号调节装置可以根据变更码本信息获取第二码本。对于终端重复发送的上行信号，信号调节装置对其中的第一上行信号采用第一码本进行中继，对其中的第二上行信号采用第二码本进行中继，如此达到对第一上行信号和第二上行信号的中继方式不一样。
第二种，通过第一码本对第一上行信号进行中继，通过对第一码本变更相位后获得的第三码本对第二上行信号进行中继。
可以理解的是，如果第二配置信息中包含变更相位信息，那么信号调节装置可以根据变更相位信息对第一码本进行相位变更，得到第三码本。对于终端重复发送的上行信号，信号调节装置对其中的第一上行信号采用第一码本进行中继，对其中的第二上行信号采用第三码本进行中继，如此达到对第一上行信号和第二上行信号的中继方式不一样。
第三种，通过第一码本对第一上行信号进行中继，通过停止中继的策略对第二上行信号进行中继。
可以理解的是，如果信号调节装置为RIS，第二配置信息中包含停止中继指示信息，那么对于终端重复发送的上行信号，RIS可以对其中的第一上行信号采用第一码本进行中继，对其中的第二上行信号采用停止中继的策略进行中继，具体地，可以在中继第二上行信号时关闭面板，达到停止中继目的。
可以理解的是，采用不同方式中继的信号在网络设备侧会具有较大的差别性；而终端直接重复发送给网络设备的多个上行信号没有经过特殊处理，所以在网络设备侧不会具有较大的差别性。这样，网络设备就可以根据接收到的重复发送的上行信号是否具有较大差别性，来确定这些上行信号是经信号调节装置中继而来，还是由终端直接发送。例如，根据接收到的多个上行信号的信号质量信息确定终端的类型。

本申请实施例的方案，网络设备向终端下发第一配置信息，第一配置信息用于指示终端在接收到随机接入响应消息后重复发送多个上行信号，多个上行信号包括第一上行信号和第二上行信号；网络设备向信号调节装置下发第二配置信息，第二配置信息用于指示信号调节装置通过不同的预设方式中继第一上行信号和第二上行信号；网络设备当接收到终端根据随机接入响应消息重复发送的多个上行信号，则根据上行信号接收情况确定终端的类型。由于经信号调节装置接入的终端，其发送的多个上行信号被信号调节装置以不同的预设方式中继给网络设备，使得这些以不同的预设方式中继的上行信号在网络设备侧具有较大的差别性，因而网络设备能够根据接收到的多个上行信号之间的差别性，判断这些来自终端的上行信号是由终端直接发送，还是经信号调节装置中继发送，进而实现在接入阶段中识别终端类型。
