这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开实施例中，为降低移动通信系统中网络设备的功耗，可以使得网络设备在满足设定的休眠条件时，进入休眠状态，处于休眠状态的网络设备停止下行发送或者只下行发送少量的信息，例如只下行发送发现参考信号(Discovery Reference Signal，DRS)。休眠的网络设备仍具有上行接收功能，当用户设备需要进行通信服务时，再唤醒休眠的网络设备，网络设备被唤醒后，恢复正常的收发功能，为用户设备提供通信服务。
在一些实施方式中，休眠条件可以包括：网络设备当前未连接有处于通信状态的用户设备。
在另一些实施方式中，休眠条件可以包括：网络设备当前未连接有处于通信状态的用户设备，且该网络设备处于另一网络设备的覆盖范围内。例如，网络设备可以是小基站，小基站在确定当前未连接有处于通信状态的用户设备，且确定自身处于宏基站的覆盖范围内时，可以进入休眠状态，当小基站进入休眠后，仍然有宏基站为此区域提供通信服务，保障用户设备的正常通信。
目前相关技术中未给出唤醒网络设备的具体实现方式，由此，本公开实施例提供一种唤醒设备的方法，以下结合附图对本公开进行解释说明。
下面首先介绍本公开实施例的实施环境。
本公开实施例的技术方案可以应用于各种通信系统。该通信系统可以包括4G(the 4th Generation，第四代)通信系统、5G(the 5th Generation，第五代)通信系统、和其他未来的无线通信系统(比如6G)中的一种或多种。
图1是根据一示例性实施例示出的一种通信系统的示意图。如图1所示，该通信系统可以包括用户设备101、第一网络设备102和第二网络设备103。该通信系统可以用于支持4G网络接入技术，例如长期演进(Long Term Evolution，LTE)接入技术，或者，5G网络接入技术，如新型无线接入技术(New Radio Access Technology，New RAT)，或者，其他未来的无线通信技术。需要说明的是，在该通信系统中，用户设备101、第一网络设备102和第二网络设备103的数量均可以为一个或多个，图1所示的通信系统中的用户设备101、第一网络设备102和第二网络设备103的数量仅为适应性举例，本公开对此不做限定。
图1中的第一网络设备102和第二网络设备103作为网络设备，可以用于支持用户设备101的接入和通信服务，例如，第一网络设备102和第二网络设备103可以是LTE中的演进型基站(evolutional Node B，eNB或eNodeB)，或者也可以是5G网络中的下一代基站(the next Generation Node B，gNB或gNodeB)，或者也可以是5G网络中的无线接入网(NG Radio Access Network，NG-RAN)设备，或者也可以是未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的基站、宽带网络业务网关(Broadband Network Gateway，BNG)、汇聚交换机或非3GPP(3rd Generation Partnership Project，第三代合作伙伴项目)接入设备等。
可选地，本公开实施例中的第一网络设备102和第二网络设备103可以是各种形式的基站，例如：宏基站、小基站、中继站、接入点、5G基站，或未来的基站、卫星、传输点(Transmitting and Receiving Point，TRP)、发射点(Transmitting Point，TP)、移动交换中心以及设备到设备(Device-to-Device，D2D)、机器到机器(Machine-to-Machine，M2M)、物联网(Internet of Things，IoT)、车联网(Vehicle-to-Everything，V2X)或其他通信中承担基站功能的设备等，本公开实施例对此不作具体限定。
图1中的用户设备101(User Equipment，UE)也可以称作用户终端，可以包括但不限于智能手机、智能可穿戴设备、智能音箱、智能平板、无线调制解调器(modem)、无线本地环路(Wireless Local Loop，WLL)台、PDA(Personal Digital Assistant，个人数字助理)、CPE(Customer Premise Equipment，客户终端设备)等。随着无线通信技术的发展，可以接入通信系统、可以与通信系统的网络设备进行通信、可以通过通信系统与其它物体进行通信的设备都可以是本公开实施例中的用户设备101；例如，智能交通中的终端和汽车、智能家居中的家用设备、智能电网中的电力抄表仪器、电压监测仪器、环境监测仪器、智能安全网络中的视频监测仪器、收款机等。用户设备101可以是静态固定的，也可以是移动的，本公开对此不作限定。在本公开实施例中，用户设备101可以与第一网络设备102和第二网络设备103进行通信。
需要说明的是，本公开实施例提供的唤醒设备的方法可以适用于异构网络，例如通信系统以“宏基站+小基站”的组网方式为用户设备101提供通信服务。其中，宏基站主要用于室外覆盖，覆盖范围较广，并且采用大量的小基站协同宏基站进行连续覆盖和室内浅层覆盖。其中，小基站包括但不限于微基站、皮基站和飞基站。
在本公开实施例中，第一网络设备102可以为宏基站，第二网络设备103可以为该宏基站的覆盖范围内的小基站。
在图1中，第一网络设备102用于发送第二网络设备103的物理随机接入信道(Physical Random Access Channel，PRACH)配置，用户设备101用于根据第一网络设备102发送的第二网络设备103的PRACH配置，在第二网络设备103的PRACH信道上发送用于唤醒第二网络设备103的信息，第二网络设备103在接收到用户设备101在PRACH信道上发送的用于唤醒的信息后，从休眠状态进入唤醒状态，恢复正常的收发功能，为用户设备101提供通信服务。
其中，更加具体的实施过程可以参见下述的相关实施例。
图2是根据一示例性实施例示出的一种唤醒设备的方法的流程图，应用于第一网络设备。请参照图2，该方法包括：
S201，发送第二网络设备的PRACH配置，该PRACH配置用于用户设备在第二网络设备的PRACH信道上发送用于唤醒第二网络设备的信息。
上述技术方案中，通过第一网络设备发送第二网络设备的PRACH配置，使得用户设备能够在第二网络设备休眠的情况下，获取到第二网络设备的PRACH配置，从而用户设备能够根据第二网络设备的PRACH配置，在第二网络设备的PRACH信道上发送用于唤醒第二网络设备的信息，进而实现唤醒第二网络设备。
可选地，第一网络设备可以通过广播方式发送第二网络设备的PRACH配置。
在一种实施方式中，在发送第二网络设备的PRACH配置之前，第一网络设备可以与第二网络设备协商该第二网络设备的PRACH配置。
协商PRACH配置的过程可以是由第二网络设备发起，比如可以是第二网络设备发起协商时携带一个PRACH配置，第一网络设备返回确认该配置，也可以是第二网络设备发起协商时携带多个PRACH配置，第一网络设备返回确认其中的一个配置。
协商PRACH配置的过程也可以是由第一网络设备发起，比如可以是第一网络设备发起协商时携带一个PRACH配置，第二网络设备返回确认该配置，也可以是第一网络设备发起协商时携带多个PRACH配置，第二网络设备返回确认其中的一个配置。
在本公开的一些实施例中，第二网络设备的PRACH配置可以包括以下至少一者：
第二网络设备的PRACH信道的时域资源；
第二网络设备的PRACH信道的频域资源；
第二网络设备的随机接入前导序列(preamble)。
例如，在一些实施例中，第二网络设备的PRACH配置包括第二网络设备的PRACH信道的频域资源，该频域资源包括第一偏移信息，第一偏移信息用于指示第二网络设备的PRACH信道的频域起始位置相对于第一网络设备的公共物理资源块0(common PRB0)的频域偏移。
通过第一偏移信息，使得用户设备能够在第二网络设备休眠的情况下，根据第一网络设备的公共物理资源块0的位置，确定出第二网络设备的PRACH信道的频域起始位置。
另外，在通信协议中，需要接入小区的用户设备可以在网络设备的PRACH信道上发送随机接入前导序列以发起随机接入。在此基础上，在一些实施例中，第二网络设备的PRACH配置可以包括第二网络设备的随机接入前导序列。其中，第二网络设备的 PRACH配置中包括的随机接入前导序列的数量可以为一个或多个。
在此基础上，用户设备在第二网络设备的PRACH信道上发送的用于唤醒第二网络设备的信息可以包括第二网络设备的PRACH配置中的随机接入前导序列。
在一种示例中，当第二网络设备的PRACH配置中包括多个随机接入前导序列时，用户设备可以在多个随机接入前导序列中选择一个随机接入前导序列，在第二网络设备的PRACH信道上发送所选择的随机接入前导序列。该随机接入前导序列作为用于唤醒第二网络设备的信息，第二网络设备响应于在自身PRACH信道上接收到相应的随机接入前导序列，进入唤醒状态。
上述技术方案中，通过将通信协议里的随机接入前导序列重用为用于唤醒第二网络设备的信息，使得在具体实施时可以将唤醒设备的过程重用到随机接入过程中，有利于在第二网络设备被唤醒后快速进入随机接入过程，在实际部署实施时十分方便。
图3是根据一示例性实施例示出的一种唤醒设备的方法的流程图，应用于第一网络设备。请参照图3，该方法包括：
S301，发送第一网络设备的同步信号块以及发送第一参数，该第一参数用于指示用户设备根据第一网络设备的同步信号块获得第二网络设备的下行同步。
在一种实施方式中，第一网络设备在同步信道上广播同步信号块，如SSB(Synchronization Signal and PBCH block，同步信号和PBCH块)，并且广播第一参数。
上述技术方案中，通过第一网络设备发送第一网络设备的同步信号块，以及通过第一网络设备发送第一参数，使得用户设备接收到第一网络设备发送的同步信号块和第一参数后，能够根据第一网络设备的同步信号块和第一参数来获得第二网络设备的下行同步，便于根据第二网络设备的下行同步，在第二网络设备的PRACH信道上发送用于唤醒第二网络设备的信息。
可以理解的是，在第二网络设备处于休眠状态下，第二网络设备通常不再广播自己的同步信号块(SSB)，因此用户设备无法通过第二网络设备的同步信号块来直接获得第二网络设备的下行同步。而通过第一网络设备发送的同步信号块和第一参数，使得在第二网络设备处于休眠状态下，用户设备能够获得第二网络设备的下行同步。
在本公开的一些实施例中，用户设备可以根据第一网络设备的同步信号块先获得第一网络设备的下行同步，然后再根据第一网络设备的下行同步和第一参数，来获得第二网络设备的下行同步。
在本公开的一些实施例中，第一参数用于指示第二网络设备与第一网络设备的下行定时相同，或者用于指示第二网络设备与第一网络设备间的下行定时时差。
例如，在第一参数用于指示第二网络设备与第一网络设备的下行定时相同的情况下，用户设备可以将第一网络设备的下行同步作为第二网络设备的下行同步。
例如，在第一参数用于指示第二网络设备与第一网络设备间的下行定时时差的情况下，用户设备可以根据第一网络设备的下行同步，和第一参数指示的第二网络设备与第一网络设备间的下行定时时差，获得第二网络设备的下行同步。

S401，发送针对第二网络设备的唤醒时延。
其中，唤醒时延用于指示从用户设备发送用于唤醒第二网络设备的信息，到用户设备接收到该第二网络设备发送的同步信号块之间的时延。
在一种实施方式中，用户设备接收第一网络设备发送的针对第二网络设备的唤醒时延，在发送用于唤醒第二网络设备的信息之后开始计时，如果在对应的唤醒时延内未接 收到该第二网络设备发送的同步信号块，则可以尝试采取其他相应措施，如增加上行发送功率或者改换另外的第二网络设备来进行唤醒。
通过发送第二网络设备的唤醒时延，使得用户设备可以在第二网络设备超时未唤醒的情况下，采取其他相应措施，避免长时间等待该第二网络设备的同步信号块。
图5是根据一示例性实施例示出的一种唤醒设备的方法的流程图，应用于第一网络设备。请参照图5，该方法包括：
S501，发送第二偏移信息，该第二偏移信息用于指示第二网络设备的同步信号块的频域位置相对于第一网络设备的同步信号块的频域位置的频域偏移。
通过发送第二偏移信息，使得用户设备能够根据第一网络设备的同步信号块的频域位置，和第二偏移信息所指示的频域偏移，确定第二网络设备的同步信号块的频域位置，这样便于在第二网络设备被唤醒后，用户设备能够在对应的频域位置上直接监听第二网络设备的同步信号块，而无须用户设备在不同频域上进行同步信号块的搜索。

S701，接收第一网络设备的同步信号块以及接收第一参数。
S702，根据第一网络设备的同步信号块以及第一参数，获得第二网络设备的下行同步。
在一种实施方式中，第一网络设备在同步信道上广播同步信号块，如SSB，并且广播第一参数，因此用户设备可以接收到第一网络设备广播的同步信号块和第一参数。
上述技术方案中，用户设备能够通过第一网络设备的同步信号块和第一参数，获得第二网络设备的下行同步。
图8是根据一示例性实施例示出的一种唤醒设备的方法的流程图，应用于用户设备。请参照图8，该方法包括：
S801，接收第一网络设备的同步信号块以及接收第一参数。
S802，根据第一网络设备的同步信号块，获得第一网络设备的下行同步。
S803，根据第一网络设备的下行同步和第一参数，获得第二网络设备的下行同步。
在上述技术方案中，用户设备可以先根据第一网络设备的同步信号块获得第一网络设备的下行同步，然后再根据第一网络设备的下行同步和第一参数，获得第二网络设备的下行同步。
在一些实施例中，第一参数用于指示第二网络设备与第一网络设备的下行定时相同，或者用于指示第二网络设备与第一网络设备间的下行定时时差。
例如，第一参数用于指示第二网络设备与第一网络设备的下行定时相同。
在此情况下，在步骤S803中，用户设备可以将第一网络设备的下行同步作为第二网络设备的下行同步。
例如，第一参数用于指示第二网络设备与第一网络设备间的下行定时时差。
在此情况下，在步骤S803中，用户设备可以根据第一网络设备的下行同步，和第一参数指示的第二网络设备与第一网络设备间的下行定时时差，获得第二网络设备的下行同步。
通过第一网络设备的同步信号块和第一参数的指示，使得在第二网络设备处于休眠状态下，用户设备能够获得第二网络设备的下行同步。
在获得第二网络设备的下行同步的基础上，用户设备可以在第二网络设备的PRACH信道上发送用于唤醒第二网络设备的信息。
在本公开的一些实施例中，第二网络设备的PRACH配置可以包括以下至少一者：
第二网络设备的PRACH信道的时域资源；
第二网络设备的PRACH信道的频域资源；
第二网络设备的随机接入前导序列(preamble)。
例如，在一些实施例中，第二网络设备的PRACH配置包括第二网络设备的PRACH信道的频域资源，该频域资源包括第一偏移信息，第一偏移信息用于指示第二网络设备的PRACH信道的频域起始位置相对于第一网络设备的公共物理资源块0(common PRB0)的频域偏移。
图9是根据一示例性实施例示出的一种唤醒设备的方法的流程图，应用于用户设备。请参照图9，该方法包括：
S901，根据第一网络设备的公共物理资源块0的位置，和PRACH配置中的第一偏移信息，确定第二网络设备的PRACH信道的频域起始位置。
具体而言，用户设备在接收到第一网络设备的同步信号块之后，可以根据第一网络设备的同步信号块确定第一网络设备的common PRB0的位置，然后再根据第一网络设备的common PRB0的位置，和上述PRACH配置中的第一偏移信息，确定第二网络设备的PRACH信道的频域起始位置。
通过第一偏移信息，使得用户设备能够在第二网络设备休眠的情况下，确定出第二网络设备的PRACH信道的频域起始位置。
另外，在通信协议中，需要接入小区的用户设备可以在网络设备的PRACH信道上发送随机接入前导序列以发起随机接入。在此基础上，在一些实施例中，第二网络设备的PRACH配置可以包括第二网络设备的随机接入前导序列。其中，第二网络设备的PRACH配置中包括的随机接入前导序列的数量可以为一个或多个。
图10是根据一示例性实施例示出的一种唤醒设备的方法的流程图，应用于用户设备。请参照图10，该方法包括：
S1001，接收第二网络设备的PRACH配置，该PRACH配置包括第二网络设备的随机接入前导序列。
S1002，在第二网络设备的PRACH信道上发送该PRACH配置中的随机接入前导序列。
在一种示例中，当第二网络设备的PRACH配置中包括多个随机接入前导序列时，用户设备可以在多个随机接入前导序列中选择一个随机接入前导序列，在第二网络设备的PRACH信道上发送所选择的随机接入前导序列。该随机接入前导序列作为用于唤醒第二网络设备的信息，第二网络设备响应于在自身PRACH信道上接收到相应的随机接入前导序列，进入唤醒状态。随后可以进行随机接入过程。
上述技术方案中，通过将通信协议里的随机接入前导序列重用为用于唤醒第二网络设备的信息，使得在具体实施时可以将唤醒设备的过程重用到随机接入过程中，有利于在第二网络设备被唤醒后快速进入随机接入过程，在实际部署实施时十分方便。
图11是根据一示例性实施例示出的一种唤醒设备的方法的流程图，应用于用户设备。请参照图11，该方法包括：

图12是根据一示例性实施例示出的一种唤醒设备的方法的流程图，应用于用户设备。请参照图12，该方法包括：
S1201，接收第二网络设备的PRACH配置。
S1202，根据第二网络设备的PRACH配置，在第二网络设备的PRACH信道上发送用于唤醒第二网络设备的信息。
S1203，响应于在对应的唤醒时延内未接收到第二网络设备发送的同步信号块，在另一个第二网络设备的PRACH信道上发送用于唤醒另一个第二网络设备的信息。
上述技术方案中，用户设备在第二网络设备的PRACH信道上发送用于唤醒第二网络设备的信息之后，如果在该第二网络设备对应的唤醒时延内未接收到该第二网络设备发送的同步信号块，那么可以改为在另一个第二网络设备的PRACH信道上发送用于唤醒另一个第二网络设备的信息。
在一种实施方式中，第一网络设备可以发送对应于多个第二网络设备的PRACH配置，用户设备可以选择其中一个第二网络设备的PRACH配置，根据选择的第二网络设备的PRACH配置，在该第二网络设备对应的PRACH信道上发送用于唤醒该第二网络设备的信息。如果在该第二网络设备对应的唤醒时延内未接收到该第二网络设备发送的同步信号块，则可以重新选择另一个第二网络设备的PRACH配置，根据新选择的另一个第二网络设备的PRACH配置，在该另一个第二网络设备的PRACH信道上发送用于唤醒该另一个第二网络设备的信息。
在此基础上，第一网络设备还可以发送对应于多个第二网络设备的第一参数。这样，如果用户设备重新选择了另一个第二网络设备，则可以根据该另一个第二网络设备的第一参数，获得该另一个第二网络设备的下行同步。用户设备可以在获得另一个第二网络设备的下行同步的基础上，在该另一个第二网络设备的PRACH信道上发送用于唤醒该另一个第二网络设备的信息。
可以理解的，各第二网络设备对应的唤醒时延可以是相同的，也可以是不同的，例如在通信协议内约定一个统一的唤醒时延，又例如第一网络设备针对不同的第二网络设备配置不同的唤醒时延。
在图11～图12中，唤醒时延可以是在通信协议内约定。
在图11～图12中，唤醒时延可以是通过第一网络设备发送的。
因此，该唤醒设备的方法还包括：
接收第一网络设备发送的针对第二网络设备的唤醒时延。
可以理解的，通过通信协议内约定的或第一网络设备发送的唤醒时延，使得用户设备可以在第二网络设备超时未唤醒的情况下，采取其他相应措施，避免长时间等待该第二网络设备的同步信号块。

图15是根据一示例性实施例示出的一种唤醒设备的方法的流程图，应用于第二网络设备。请参照图15，该方法包括：
S1501，在休眠状态下，响应于接收到用户设备根据第二网络设备的PRACH配置，在第二网络设备的PRACH信道上发送的用于唤醒第二网络设备的信息，进入唤醒状态。
在一种示例中，第二网络设备在满足设定的休眠条件时，可以进入休眠状态。处于休眠状态的第二网络设备停止下行发送或者只下行发送少量的信息，例如只下行发送DRS。休眠状态下的第二网络设备具有上行接收功能，能够接收用户设备上行发送的唤醒信号。
在上述技术方案中，第二网络设备能够响应于用户设备在PRACH信道上发送的用于唤醒的信息，从休眠状态进入唤醒状态，恢复正常的收发功能，为用户设备提供通信服务。
第二网络设备进入唤醒状态后，将会恢复正常的收发功能，因此第二网络设备可以正常在同步信道广播同步信号块(SSB)。
因此，该方法还包括：在进入唤醒状态后，发送同步信号块。
可选地，用户设备可以根据第二网络设备对应的唤醒时延，检测是否在对应唤醒时延内接收到第二网络设备发送的同步信号块，如果未能在对应唤醒时延内接收到第二网络设备发送的同步信号块，那么相应地增加上行发送功率再次发送，或者改为在另一个第二网络设备的PRACH信道上发送用于唤醒该另一个第二网络设备的信息。
可选地，用户设备可以根据第二网络设备的同步信号块的频域位置，在第二网络设备的同步信号块的频域位置监听第二网络设备的同步信号块。

第二网络设备的PRACH信道的频域资源；
第二网络设备的随机接入前导序列(preamble)。
在一些实施例中，用于唤醒第二网络设备的信息可以包括第二网络设备的PRACH配置中的随机接入前导序列。
上述技术方案中，通过将通信协议里的随机接入前导序列重用为用于唤醒第二网络设备的信息，使得在具体实施时可以将唤醒设备的过程重用到随机接入过程中，有利于在第二网络设备被唤醒后快速进入随机接入过程，在实际部署实施时十分方便。
图16是根据一示例性实施例示出的一种唤醒设备的方法的流程图，应用于第二网络设备。请参照图16，该方法包括：
S1601，与第一网络设备协商该第二网络设备的PRACH配置。
在一种示例中，第二网络设备可以与第一网络设备协商该第二网络设备的PRACH配置。
协商PRACH配置的过程可以是由第二网络设备发起，比如可以是第二网络设备发起协商时携带一个PRACH配置，第一网络设备返回确认该配置，也可以是第二网络设备发起协商时携带多个PRACH配置，第一网络设备返回确认其中的一个配置。
协商PRACH配置的过程也可以是由第一网络设备发起，比如可以是第一网络设备发起协商时携带一个PRACH配置，第二网络设备返回确认该配置，也可以是第一网络设备发起协商时携带多个PRACH配置，第二网络设备返回确认其中的一个配置。
在一示例性实施例中，第二网络设备可以根据第二网络设备的PRACH配置，当在PRACH信道的时频资源上检测到相应的随机接入前导序列的情况下，认为接收到对应于本设备的唤醒信号，于是进入唤醒状态。
此外，对于用户设备获得第二网络设备的PRACH配置的具体过程，获得第二网络设备的下行同步的具体过程，获得第二网络设备的唤醒时延的具体过程，以及获得第二网络设备的同步信号块的频域位置的具体过程，已经在前文有关的实施例中进行了说明，在此不重复赘述。
下面以第一网络设备为宏基站，第二网络设备为该宏基站的覆盖范围内的小基站为例，对本技术方案进行说明。
在本公开中，首先，宏基站广播至少一个PRACH配置，每个PRACH配置对应于该宏基站的覆盖范围内的至少一个小基站。每个PRACH配置包括对应的小基站的PRACH信道的时域资源、频域资源和小基站的随机接入前导序列。可以理解的，当多个小基站的PRACH信道的时域资源、频域资源和随机接入前导序列相同的情况下，可以通过一个PRACH配置同时对应这多个小基站。
在此之前，宏基站可以分别与每个小基站协商该小基站的PRACH配置，协商PRACH配置的过程可以由宏基站发起或由小基站发起，具体的协商过程可以参见前述的说明。
另外，宏基站还广播SSB和至少一个第一参数，该第一参数用于指示用户设备根据宏基站的SSB获得对应的小基站的下行同步。该第一参数可以指示小基站与宏基站的下行定时相同，或者指示小基站与宏基站的下行定时时差。该第一参数可以配置多个，每个第一参数分别对应于一个小基站。
然后，用户设备根据宏基站的SSB首先获得宏基站的下行同步，再根据第一参数获得小基站的下行同步。
然后，用户设备根据宏基站广播的其中一个PRACH配置，在对应的PRACH信道上发送被配置的随机接入前导序列，用于唤醒对应的小基站。该小基站被唤醒后，将在同步信道上广播SSB。
此外，宏基站还可以配置各个小基站对应的唤醒时延，如果用户设备在发送随机接入前导序列之后的唤醒时延内未接收到对应的小基站的SSB，可以增加上行发送功率再次发送被配置的随机接入前导序列，或者改为在另一个小基站的PRACH信道上发送另一个小基站被配置的随机接入前导序列。
应理解，由于用户设备之前已经获得宏基站广播的各个小基站对应的PRACH配置和第一参数，因此，可以很方便地获得另一个小基站的PRACH配置和下行同步。
在一些实施例中，宏基站在配置各个小基站的PRACH信道的频域资源时，频域资源包括第一偏移信息，第一偏移信息用于指示对应的小基站的PRACH信道的频域起始位置相对于该宏基站的公共物理资源块0的频域偏移，从而用户设备可以确定对应的小基站的PRACH信道的频域起始位置。
在一些实施例中，宏基站还可以配置各个小基站的SSB的频域位置相对于该宏基站的SSB的频域位置的第二偏移信息，这样便于在小基站唤醒后，用户设备能够在对应的频域位置上直接监听到小基站的SSB，而无须在不同频域上进行SSB的搜索。
