为了便于理解本申请实施例，下面对本申请实施例所涉及到的基本流程以及基本概念进行简单说明。应理解，下文所介绍的基本流程以及基本概念并不对本申请实施例产生限定。
5G的主要应用场景为：增强移动超宽带(eMBB，Enhanced Mobile Broadband)、低时延高可靠通信(URLLC，Ultra Reliable Low Latency Communications)、大规模机器类通信(mMTC，massive Machine Type Communications)。其中，eMBB以用户获得多媒体内容、服务和数据为目标，其需求增长十分迅速；由于eMBB可能部署在不同的场景中，便如室内，市区，农村等，其能力和需求的差别也比较大，所以必须结合具体的部署场景详细分析。URLLC的典型应用包括：工业自动化，电力自动化，远程医疗操作(手术)，交通安全保障等。mMTC的典型特点包括：高连接密度、小数据量、时延不敏感业务、低成本和长使用寿命等。
在5G网络环境中，为了降低空口信令和快速恢复无线连接，快速恢复数据业务的目的，定义了新的RRC(无线资源控制，Radio Resource Control)状态，即RRC_INACTIVE(RRC非激活)状态。这种状态有别于RRC_IDLE(RRC空闲)状态、RRC_ACTIVE(RRC激活)或RRC_CONNECTED(RRC连接)状态。
关于终端设备(或称为UE)的节能，分别进行说明：
第一、针对RRC连接态的终端设备的节能：在5G的演进中，对UE(即终端设备)的节电提出了更高的要求。例如对于现有的DRX(Discontinuous Reception，非连续接收)机制，在每个on duration(激活时间)，UE(即终端设备)需要不断检测PDCCH(物理下行控制信道，Physical Downlink Control CHannel)来判断基站是否调度发给自己的数据传输。对于大部分UE(即终端设备)来说，可能在很长一段时间没有接收数据传输的需要，仍然需要保持定期的唤醒机制来监听可能的下行传输，对于这类UE(即终端设备)，节电有进一步优化的空间。
在R16标准中，引入了节能信号，以实现进一步的节能。该节能信号可以与DRX机制结合使用，该引入节能信号的处理方式，具体可以包括：终端设备在DRX ON duration(激活时间)之前，接收节能信号(或称为节能唤醒信号)。也就是，当针对一个终端设备在一个DRX周期有数据传输时，网络设备可以通过节能信号“唤醒”终端设备，以使得所述终端设备在唤醒后，在DRX On duration期间监听PDCCH；否则，当针对一个终端设备在一个DRX周期没有数据传输时，不向该终端设备发送节能信号(也就是不“唤醒”终端设备)，以使得该终端设备在DRX On Duration期间不需要监听PDCCH。相比现有DRX机制，上述引入节能信号的处理方式，能够在终端设备没有数据传输时，省略DRX On duration期间PDCCH监听，从而实现终端设备的节能。其中，所述节能信号，可以由DCI(下行链路控制信息，DownLink Control Information)format(格式)2_6承载。
将终端设备在DRX(Discontinuous Reception，非连续接收)On duration之外的时间被称为非激活 时间，在DRX On Duration的时间被称为激活时间，结合图2，对以上在DRX中引入节能信号的处理方式进行说明，可以包括：第一个节能信号指示监听PDCCH，则终端设备在接收到该第一个节能信号后，在第一个DRX周期的激活时间(第一个DRX周期的激活时间在图2中表示为黑色方框)内监听PDCCH；第二个节能信号指示不监听PDCCH，则终端设备在接收到该第二个节能信号后，不在第二个DRX周期的激活时间(第二个DRX周期的激活时间在图2中表示为无颜色方框)内监听PDCCH；第三个节能信号指示不监听PDCCH，则终端设备在接收到该第三个节能信号后，不在第三个DRX周期的激活时间(第三个DRX周期的激活时间在图2中表示为无颜色方框)内监听PDCCH；第四个节能信号指示监听PDCCH，则终端设备在接收到该第四个节能信号后，在第四个DRX周期的激活时间(第四个DRX周期的激活时间在图2中表示为黑色方框)内监听PDCCH。
在R17标准中，为了进一步增强连接态(即RRC连接态)的UE(即终端设备)的节能，引入了R16的搜索空间集合组切换的增强方案，以及在数据传输的间隙跳过PDCCH监听的方案(即PDCCH skipping(跳过)的方案)来实现节电。其中，搜索空间集合组切换和PDCCH skipping相关的控制信息可以是通过PDCCH承载的。
第二、针对RRC-Idle(RRC空闲态)/RRC-inactive(RRC非激活态)态终端设备的节能：在RRC idle/inactive状态下的终端设备，通过DRX的方式接收寻呼消息。由于在一个DRX周期内存在一个寻呼时机(paging occasion，PO)，因此终端设备只在PO接收寻呼消息，而在PO之外的时间不接受寻呼消息，来达到省电的目的。但是实际情况下，终端设备被寻呼到的概率可能并不高，因此，若终端设备周期性的在对应的PO上检测PDCCH，而有很大概率并没有检测到发给自己的寻呼消息，则客观上会造成功率的浪费。
与R16标准针对RRC连接态的终端设备的节能类似，R17标准对空闲态的终端设备接收寻呼消息的节能进行了优化，引入了与前述节能信号类似的一种节能信号，称为PEI(paging early indication，寻呼早期指示)。该PEI用于在目标PO到达之前，指示终端设备是否在该PO接收寻呼PDCCH。上述节能信号(即PEI)承载于PDCCH信道(以下为了方便描述，将其称为基于PDCCH信道的节能信号)，具体通过DCI(下行链路控制信息，DownLink Control Information)format(格式)2_7携带该节能信号(即PEI)。该基于PDCCH信道的节能信号可以承载更多的节能信息，例如，可以承载sub-grouping(子分组)信息，用于指示节能信息对应的终端设备子分组(或UE子分组)。可通过UE_ID(标识)将对应同一个PO的多个终端设备的进一步分组，得到多个终端设备组。若终端设备所在的终端设备组有任何一个终端设备需要被寻呼，则终端设备需要在该PO上接收寻呼消息，否则，终端设备不需要接收寻呼消息。以上通过将终端设备组(或称为终端设备子分组)信息与节能信息结合，可以更加精细的指示在目标PO是否需要接收寻呼的终端设备。比如，通过节能信号唤醒终端设备接收寻呼消息的一种场景，如图3所示：第一个节能信号指示一个或多个终端设备组中的终端设备在对应的PF(寻呼帧，Paging Frame)或者PO(在图3中将第一个节能信号所指示的PF或PO表示为灰色方块)上接收寻呼，则该终端设备组内的终端设备唤醒后，在PF或PO上监听寻呼；第二个节能信号则指示不监听PDCCH，也就是指示一个或多个终端设备组中的终端设备在对应的PF或者PO(在图3中将第二个节能信号所指示的PF或PO表示为无颜色方块)上不接收寻呼，则该终端设备组内的终端设备可以不在PF或PO上监听寻呼；第三个节能信号指示一个或多个终端设备组中的终端设备在对应的PF或者PO(在图3中将第三个节能信号所指示的PF或PO表示为灰色方块)上接收寻呼，则该终端设备组内的终端设备唤醒后，在PF或PO上监听寻呼。
为了终端设备的进一步节电，R18标准计划引入唤醒接收机(WUR,wake-up receiver)接收节能信号的方案。WUR具有极低成本、极低复杂度和极低功耗的特点，其主要通过基于包络检测的方式接收节能信号。因此，WUR接收的节能信号与现有R16、R17标准定义的基于PDCCH承载的信号的调制方式、波形等不同。节能信号主要通过对载波信号进行ASK调制的包络信号。包络信号的解调也可基于无线射频信号提供的能量驱动低功耗电路来完成，因此它可以是无源的。WUR也可以通过终端设备进行供电，无论哪种供电方式，该WUR相比终端设备的传统接收机都极大的降低了功耗，例如WUR可以实现小于1mw(毫瓦)的功耗，远低于传统接收机几十至几百mw的功耗。WUR可以和终端设备结合在一起，作为终端设备接收机的一个附加模块，也可以单独作为一个终端设备的唤醒功能模块。

应理解，在本申请的实施例中提到的“指示”可以是直接指示，也可以是间接指示，还可以是表示具有关联关系。举例说明，A指示B，可以表示A直接指示B，例如B可以通过A获取；也可以表示A间接指示B，例如A指示C，B可以通过C获取；还可以表示A和B之间具有关联关系。
在本申请实施例的描述中，术语“对应”可表示两者之间具有直接对应或间接对应的关系，也可以表示两者之间具有关联关系，也可以是指示与被指示、配置与被配置等关系。
为便于理解本申请实施例的技术方案，以下对本申请实施例的相关技术进行说明，以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。
图4是根据本申请第一方面实施例的通信方法的示意性流程图。该方法可选地可以应用于图1所示的系统，但并不仅限于此。该方法包括以下内容的至少部分内容。
S410、终端设备监听唤醒信号(WUS，wake-up Signal)；其中，所述WUS用于唤醒所述终端设备；所述WUS中携带第一信息，所述第一信息用于所述终端设备在唤醒后执行的操作。
所述终端设备监听所述WUS，可以指的是：所述终端设备处于空闲态的情况下，监听所述WUS。所述终端设备具体可以为低功耗设备；或者所述低功耗设备还可以称为零功耗设备。该终端设备，即所述低功耗设备，可以包括第一部件以及第二部件，所述第一部件的功耗低于所述第二部件，相应的，上述S410所述终端设备监听WUS，可以为：所述终端设备的第一部件监听所述WUS。再具体的，可以为：所述终端设备处于RRC空闲态的情况下，所述终端设备的第一部件监听所述WUS。
需要指出的是，在所述终端设备的第一部件监听所述WUS的过程中，所述终端设备的所述第二部件可以处于休眠状态。该休眠状态可以指的是所述第二部件一部分功能或一部分器件处于开启状态，但是另一部分功能或另一部分器件处于关闭状态或称为待唤醒状态等等。所述终端设备可以仅包含上述第一部件和第二部件；或者，所述终端设备除了包含上述第一部件和第二部件之外，还可以包含其他部件，只是本实施例不做穷举。
所述第一部件可以指的是所述终端设备中的低功耗接收机，或者可以称为唤醒接收机(WUR，wake-up receiver)，或者可以称为零功耗WUR，或者还可以称为低功耗WUR，或者还可以称为低功耗电路，关于该第一部件更多的名称本实施例不做穷举。所述第二部件可以指的是所述终端设备中的主接收机。
示例性的，结合图5，对前述终端设备进行说明，该终端设备由图5中所示的主接收机以及WUR构成。进一步的，如果网络设备需要终端设备开启或唤醒第二部件即图5中的主接收机，则所述网络设备可以向所述终端设备发送WUS。相应的，所述终端设备的WUR可以监听所述WUS；在终端设备的WUR监听到所述WUS的情况下，控制开启或唤醒所述终端设备的主接收机(即前述第二部件)；在终端设备的WUR没有监听到所述WUS的情况下，终端设备的主接收机可以保持处于休眠状态。也就是说，在终端设备没有业务或没有寻呼消息时，终端设备可以仅使用WUR(即第一部件)持续进行WUS监听；仅当终端设备有业务或有寻呼消息时，终端设备的WUR才会监听到WUS，再唤醒终端设备的主接收机以进行数据收发。
所述WUS为UE专属的；或者所述WUS为UE组共享的，所述UE组可以是包含所述终端设备的UE组；或者所述WUS为小区专用的，所述小区可以为所述终端设备所在的服务小区。因此，所述WUS还可以包括：UE标识，所述UE标识为UE ID或UE组UD或小区ID。
需要指出的是，所述UE标识可以包含在所述WUS中的第一信息中，或者所述UE标识可以不包含的WUS的第一信息中。本实施例不对所述UE标识在所述WUS中的具体信息位置进行限定。
其中，所述UE ID可以指的是终端设备的标识，可以为终端设备的唯一标识，比如，可以为以下任意之一：可以采用临时移动用户识别码(TMSI，Temporary Mobile Subscriber Identity)、国际移动用户识别码(IMSI，International Mobile Subscriber Identity)、I-RNTI(Inactive Radio Network Temporary Identifier，非激活无线网络临时标识)。
所述UE组可以是一个或多个终端设备所组成的；系统中可以配置一个或多个UE组，并且系统中为该一个或多个UE组中不同的UE组分配了不同的ID，以唯一区分不同的UE组。
所述小区ID可以是系统中包含的一个或多个小区分别对应的ID。所述WUS具体用于唤醒符合所述UE标识的终端设备。也就是，所述终端设备的第一部件(即WUR)在接收到所述WUS之后，基于所述WUS中携带的UE标识，确定自身为符合所述UE标识的终端设备的情况下，可以唤醒第二部件(即主接收机)。
其中，终端设备确定自身是否为符合所述UE标识的终端设备的方式，可以包括：在所述UE标识包含的为UE ID的情况下，终端设备基于自身的标识判断与所述UE ID是否相同；在相同的情况下，确定自身为符合所述UE标识的终端设备；或者，在所述UE标识包含的为UE组ID的情况下，终端设备基于自身所在的UE组的标识判断与所述UE组ID是否相同；在相同的情况下，确定自身为符合所述UE标识的终端设备；或者，在所述UE标识包含的为小区ID的情况下，终端设备基于自身所在的小区的标识判断与所述小区ID是否相同；在相同的情况下，确定自身为符合所述UE标识的终端设备。
可选的，该UE标识可以替换为比特图；在该比特图中的某一个比特位的取值可以用于表示是否唤醒唤醒对应的终端设备或UE组；举例来说，第一值表示唤醒所述终端设备，第二值表示不唤醒所述终端设备或UE组；第一值与第二值不同，比如，第一值为1、第二值为0，或者与之相反。
举例来说，所述WUS中携带比特图，所述比特图(bitmap)中可以包含Q个比特位，Q为大于等于1的整数。在所述比特图中包含的所述Q个比特位中，每个比特位可以用于对应一个UE组，且不同比特位对应不同的UE组。所述Q个比特位中，每一个比特位的取值可以用于指示是否唤醒对应的UE组中的终端设备。其中，每一个比特位的取值可以包括二进制第一值和二进制第二值。二进制第一值用于指示唤醒对应的UE组中的终端设备，也就是该二进制第一值用于指示对应的UE组中的终端设备唤醒第二部件；二进制第二值用于指示不唤醒对应的UE组中的终端设备，也就是二进制第二值用于指示UE组中的所述终端设备不唤醒第二部件。该二进制第一值和二进制第二值不同，比如二进制第一值为1、二进制第二值为0，或者二进制第一值为0、二进制第二值为1。比如，终端设备的第一部件(即WUR)在接收到该WUS之后，从该WUS中获取比特图，从所述比特图中获取所述终端设备所在的UE组所对应的比特位的取值；若该比特位的取值为二进制第一值，则所述终端设备可以唤醒第二部件(即主接收机)。
为了便于区分，下文从调制方式、调制波形、传输速率、支持的带宽范围、码率等方面，介绍WUR与主接收机之间的差异：从二者支持的调制方式来看，WUR支持的调制方式的复杂程度低于主接收机支持的调制方式的复杂程度。在一些实现方式中，WUR支持的调制方式可以包括以下调制方式中的一种或多种：幅移键控(amplitude shift keying，ASK)、相移键控(phase shift keying，PSK)、频移键控(frequency shift keying，FSK)等。相应地，主接收机支持的调制方式可以包括以下调制方式中的一种或多种：正交相移键控(quadrature phase shift keying，QPSK)、正交振幅调制(quadrature amplitude modulation，QAM)、正交频分复用(orthogonal frequency division multiplexing，OFDM)等。当然，在另一些实现方式中，主接收机也可以支持ASK、PSK、FSK中的至少之一的调制方式。本申请实施例对此不作具体限定。从二者支持的调制波形来看，WUR支持的调制波形的复杂度低于主接收机支持的调制波形的复杂度。例如，WUR支持的调制波形可以包括以下调制波形中的一种或多种：ASK信号对应的波形、PSK信号对应的波形、FSK信号对应的波形。相应地，主接收机支持的调制波形可以包括以下调制波形中的一种或多种：QPSK信号对应的波形、QAM信号对应的波形、OFDM信号对应的波形。当然，在一些实施例中，主接收机支持的调制波形还可以包括ASK、PSK、FSK中的一种或多种信号对应的波形。从二者支持的传输速率来看，WUR支持的传输速率低于主接收机支持的传输速率。从二者支持的带宽范围来看，WUR支持的带宽范围小于主接收机支持的带宽范围，或者说，WUR支持的带宽比主接收机支持的带宽窄。从二者支持的码率来看，WUR支持的码率低于主接收机支持的码率。
本实施例提供的方案中，所述终端设备仅使用第一部件(即WUR)监听所述WUS，可以节省终端设备的功耗。这是由于终端设备的WUR工作时使用极低的功耗(一般小于1mw)；并且，终端设备的WUR使用ASK或FSK的方式对信号进行调制，这也使得终端设备的WUR可以采用极其简单的硬件结构和极其简单的接收方式对信号进行接收和解调，例如，针对ASK信号，终端设备的WUR仅需要使用包络检测的方式对信号进行接收。因此，相对传统的终端设备一直使用主接收机的模式，本实施例采用终端设备的WUR监听WUS，能够极大节省终端设备的功耗。
上述WUS，还可以称为低功耗WUS，或者还可以称为其他名称，本实施例不做穷举。
所述WUS除了可以用于唤醒所述终端设备之外，还可以携带前述第一信息，所述第一信息用于所述终端设备在唤醒后执行的操作。示例性的，所述所述终端设备在唤醒后执行的操作可以包括以下一个或多个：随机接入、初始接入、时频同步。
具体的，所述第一信息可以包括以下一个或多个信息：用于执行随机接入的信息，所述用于执行随机接入的信息为第一PRACH(Physical Random Access Channel，物理随机接入信道)资源的配置信息；用于执行初始接入的信息，所述用于执行初始接入的信息为目标初始BWP(BandWidth Part，带宽部分)资源的配置信息；用于执行时频同步的信息，所述用于执行时频同步的信息为同步信号的配置信息。

其中，所述第一PRACH的时域资源信息，下面分两种情况来说：

其中，所述第一PRACH的时域资源的时域位置，包括：所述第一PRACH的时域资源的时域起始位置，或者，所述第一PRACH的时域资源的时域结束位置。
所述第一PRACH的时域资源的持续时长，可以指的是第一PRACH资源所占用的时域长度。可以采用时隙、符号、子帧、毫秒等等中任意之一为单位。示例性的，所述第一PRACH的时域资源的持续时长可以为：1个时隙、或2个时隙，或1毫秒、或3毫秒、更长或更短，这里仅作为示例性说明，不作为对本实施例的限定。
一种实施方式中，所述第一PRACH的时域资源位置信息具体包括：所述第一PRACH的时域资源的的时域起始位置、所述第一PRACH的时域资源的持续时长。该第一PRACH的时域资源的时域起始位置、所述第一PRACH的时域资源的持续时长可以是以符号、时隙、子帧、毫秒、微秒等任意之一为单位来表示。比如，所述第一PRACH的时域资源的时域起始位置可以表示为第A1个时隙；所述第一PRACH的时域资源的持续时长可以表示为A2个毫秒。

由于所述WUS可以占用一段时域资源，本实施例中，可以指定所述WUS所占用的一段时域资源中的一个时间(或一个时刻)作为该WUS的接收时间。比如，所述WUS的接收时间，可以包括：所述WUS的起始接收时间、或者、所述WUS的接收完成时间。应理解，所述WUS的接收时间还可以为所述WUS所占用的时域资源中的其他时间，比如可以为所述WUS所占用的时域资源的中点时间等等，只要所述终端设备与所述网络设备双方采用相同的WUS的接收时间即可。
同样的，所述第一PRACH的时域资源也可以占用一段时域资源，可以指定所述第一PRACH的时域资源中的时间(或时刻)作为该第一PRACH的时域资源的时域位置。比如，所述第一PRACH的时域资源的时域位置，包括：所述第一PRACH的时域资源的时域起始位置，和/或，所述第一PRACH的时域资源的时域结束位置。应理解，所述第一PRACH的时域资源的时域位置还可以为所述第一PRACH的时域资源中的其他时间，比如可以为所述第一PRACH的时域资源的中点时间等等，只要所述终端设备与所述网络设备双方采用相同的第一PRACH的时域资源的时域位置即可。
所述第一时域偏移，可以包括一个数值或多个数值。所述第一时域偏移的单位可以为符号、时隙、子帧、毫秒、微秒等任意之一。
在一种可能的实施方式中，所述第一时域偏移包括一个数值，将该数值称为第一数值。所述第一数值可以用于表示所述第一PRACH的时域资源的时域起始位置，与所述WUS的接收时间(比如WUS的起始接收时间)之间的相对时间偏移；或者，该偏移值可以用于表示所述第一PRACH的时域资源的时域结束位置，与所述WUS的接收时间(比如WUS的起始接收时间)之间的相对时间偏移。
这种实施方式中，所述第一PRACH的时域资源位置信息中还可以包括：第一PRACH的时域资源的持续时长。所述终端设备可以基于前述第一PRACH的时域资源的时域起始位置(或时域结束位置)以及第一PRACH的时域资源的持续时长，确定所述第一PRACH的时域资源的具体位置。
举例来说，所述第一时域偏移为第一数值，该第一数值等于A4，该第一时域偏移的单位为时隙。则所述终端设备可以基于该WUS的起始接收时间，确定所述第一PRACH的时域资源的时域起始位置为所述WUS的起始接收时间延迟A4个时隙之后的位置。所述终端设备可以基于前述第一PRACH的时域资源的时域起始位置，加第一PRACH的时域资源的持续时长，得到第一PRACH的时域资源的时域结束位置；将第一PRACH的时域资源的时域起始位置以及时域结束位置之间的范围，作为所述第一PRACH的时域资源的具体位置。再举例来说，所述第一时域偏移为第一数值，该第一数值等于A5， 该第一时域偏移的单位为时隙。则所述终端设备可以确定所述第一PRACH的时域资源的时域起始位置为所述WUS的接收结束时间延迟A5个时隙之后的位置。所述终端设备可以基于前述第一PRACH的时域资源的时域起始位置，加第一PRACH的时域资源的持续时长，得到第一PRACH的时域资源的时域结束位置；将第一PRACH的时域资源的时域起始位置以及时域结束位置之间的范围，作为所述第一PRACH的时域资源的具体位置。
在一种可能的实施方式中，在所述第一时域偏移包括两个数值时，比如两个数值分别表示为第二数值和第三数值；其中第二数值可以用于表示所述第一PRACH的时域资源的时域起始位置，与所述WUS的接收时间(比如WUS的起始接收时间)之间的相对时间偏移；第三数值可以表示所述第一PRACH的时域资源的时域结束位置，与所述WUS的接收时间(比如WUS的起始接收时间)之间的相对时间偏移。其中，第二数值小于第三数值。该第一时域偏移(即两个偏移值或多个偏移值)的单位可以为符号、时隙、子帧、毫秒、微秒等任意之一。
举例来说，所述第二数值为A6个时隙，第三数值等于A7个时隙，且A7大于A6。所述终端设备可以确定所述第一PRACH的时域资源的时域起始位置为所述WUS的接收结束时间延迟A6个时隙之后的位置；并确定所述第一PRACH的时域资源的时域结束位置为所述WUS的接收结束时间延迟A7个时隙之后的位置。
应理解，本实施方式中WUS的接收结束时间还可以替换为WUS的起始接收时间，或WUS的其他时间，只要网络设备和终端设备双方采用相同的时间即可。这里不再进行穷举。
在所述第一时域偏移包括两个或更多数值时，所述第一PRACH的时域资源位置信息中，可以不包含第一PRACH的时域资源的持续时长。

所述第一PRACH的频域资源的第一类频点，包括以下一个或多个：所述第一PRACH的频域资源的最低频点；所述第一PRACH的频域资源的最高频点；所述第一PRACH的频域资源的中心频点。应理解，这里仅为示例性说明，实际处理时所述第一类频点还可以为其他频点，只要终端设备和网络设备对该指定频点的定义或解释相同，即均在本实施例的保护范围内，这里不做穷举。
在一种可能的实施方式中，所述第一PRACH的频域资源位置信息中，可以仅包含所述第一PRACH的频域资源的第一类频点的位置。也就是说，该第一PRACH的频域资源位置信息中，可以不包含所述第一PRACH的频域资源的大小。此时，所述第一PRACH的频域资源的第一类频点，可以为多个频点。比如，所述第一PRACH的频域资源位置信息中，包含第一PRACH的频域资源的最低频点和中心频点的位置；或者，所述第一PRACH的频域资源位置信息中，包含第一PRACH的频域资源的最低频点和最高频点的位置。

所述第一PRACH的频域资源的第一类频点，包括以下一个或多个：所述第一PRACH的频域资源的最低频点；所述第一PRACH的频域资源的最高频点；所述第一PRACH的频域资源的中心频点。
应理解，这里仅为示例性说明，实际处理时所述第一类频点还可以为其他频点，只要终端设备和网络设备对该第一类频点的定义或解释相同，即均在本实施例的保护范围内，这里不做穷举。
其中，所述第一PRACH的频域资源的大小可以在所述第一PRACH的频域资源位置信息中包含；或者，可以为所述终端设备预先获取的，比如可以为网络设备在所述终端设备在上一次处于RRC连接态的情况下，通过DCI、RRC信令、系统消息中任意之一发送至所述终端设备的。
该第一频域偏移的单位，可以为PRB、RB、Khz、Mhz等等中任意之一。所述第一频域偏移可以包括一个或多个数值。
在一种可能的实施方式中，在所述第一频域偏移包括一个数值的时候，将该数值称为第四数值。该第一频域偏移值(即第四数值)可以用于表示所述第一PRACH的频域资源的一个第一类频点，与所述WUS的一个频域位置之间的相对频域偏移。
这种实施方式中，所述第一PRACH的频域资源位置信息中还可以包括：第一PRACH的频域资源的大小。
举例来说，以所述第一PRACH的频域资源的第一类频点为最低频点、所述WUS的频域位置为WUS占用的频域资源中的中心频点为例；所述终端设备在监听到WUS的情况下，基于所述WUS占用的频域资源中的中心频点的位置增加(或减少)第四数值，得到所述第一PRACH的频域资源的最低频点的位置。所述终端设备可以基于所述第一PRACH的频域资源的最低频点的位置，加第一PRACH的频域资源的大小，得到第一PRACH的频域资源的最高频点的位置；将第一PRACH的频域资源的最高频点以及最低频点之间的范围，作为所述第一PRACH的频域资源的具体范围。再举例来说，以所述第一PRACH的频域资源的第一类频点为中心频点、所述WUS的频域位置为WUS占用的频域资源中的最高频点为例；所述终端设备在监听到WUS的情况下，基于所述WUS的最高频点的位置增加(或减少)第四数值，得到所述第一PRACH的频域资源的中心频点的位置。所述终端设备可以基于所述第一PRACH的频域资源的中心频点的位置，加第一PRACH的频域资源的大小的1/2，得到第一PRACH的频域资源的最高频点的位置；基于所述第一PRACH的频域资源的中心频点的位置，减去第一PRACH的频域资源的大小的1/2，得到第一PRACH的频域资源的最低频点的位置；将第一PRACH的频域资源的最高频点以及最低频点之间的范围，作为所述第一PRACH的频域资源的具体范围。
在一种可能的实施方式中，在所述第一频域偏移包括两个数值，分别为第五数值和第六数值；其中，第五数值可以用于表示所述第一PRACH的频域资源的一个第一类频点，与所述WUS的一个频域位置之间的相对频域偏移；以及第六数值，用于表示所述第一PRACH的频域资源的另一个第一类频点，与所述WUS的一个频域位置之间的相对频域偏移。这种实施方式中，所述第一PRACH的频域资源位置信息中可以不包括第一PRACH的频域资源的大小。举例来说，以所述第一PRACH的频域资源的一个第一类频点为最低频点、另一个第一类频点为最高频点、所述WUS的频域位置为WUS占用的频域资源中的中心频点为例；所述终端设备在监听到WUS的情况下，基于所述WUS占用的频域资源中的中心频点的位置减少第五数值，得到所述第一PRACH的频域资源的最低频点的位置；基于所述WUS占用的频域资源中的中心频点的位置增加第六数值，得到所述第一PRACH的频域资源的最高频点的位置；将第一PRACH的频域资源的最高频点以及最低频点之间的范围，作为所述第一PRACH的频域资源的具体范围。
总的来说，前述第一PRACH的时域资源位置信息用于确定所述第一PRACH资源的时域资源范围(或称为时域位置)，前述第一PRACH的频域资源位置信息用于确定所述第一PRACH资源的频域资源范围(或称为频域范围)。上述第一PRACH资源的时域资源范围和频域资源范围，可以指的是用于随机接入的时频资源的位置(或总范围)。在实际处理中，在第一PRACH资源的时域资源范围和频域资源范围之内，还会存在更细粒度的第一PRACH时机(occasion)(或称为第一PRACH资源中的PRACH 时机)。
所述更细粒度可以指的是，在第一PRACH资源的时域资源范围和频域资源范围之内，存在一个或多个第一PRACH时机所分别对应的时域资源和频域资源。换句话说，任意一个第一PRACH时机的持续时长小于前述第一PRACH的时域资源的持续时长，和/或，任意一个第一PRACH时机的频域范围大小小于前述第一PRACH的频域资源的大小。
所述第一PRACH时机(occasion)的数量可以根据实际情况配置，具体可以包括以下一个或多个：在所述第一PRACH资源(即所述第一PRACH的时域资源范围和频域资源范围之内)中包含的第一PRACH时机的总数量；在第一PRACH的时域资源包含的第一PRACH时机的数量；在第一PRACH的频域资源包含的第一PRACH时机的数量。应理解，所述第一PRACH资源中包含的第一PRACH时机的总数量，大于或等于在第一PRACH的时域资源包含的第一PRACH时机的数量；或者，所述第一PRACH资源中包含的第一PRACH时机的总数量，大于或等于在第一PRACH的频域资源包含的第一PRACH时机的数量。
前述已经说明，所述第一PRACH时机的数量可以有一个或多个，下面实施例针对所述第一PRACH时机的时频位置说明中，可以理解为针对一个或多个第一PRACH时机中的任意之一的说明，由于针对每个第一PRACH时机的时频位置说明为相同的，因此不做一一赘述。
所述第一PRACH时机的时域资源位置信息，可以包含以下一个或多个：第一PRACH时机的时域起始位置、第一PRACH时机的时域结束位置、第一PRACH时机的持续时长。其中，所述第一PRACH时机的持续时长，小于前述第一PRACH的时域资源的持续时长。
第一PRACH时机的时域起始位置/时域结束位置，可以是以时隙、符号、子帧、毫秒等任意之一为单位来表示。
在一种可能的实施方式中，所述第一PRACH时机的时域资源位置信息，包含第一PRACH时机的时域起始位置、第一PRACH时机的时域结束位置。
在另一种可能的实施方式中，所述第一PRACH时机的时域资源位置信息，包含第一PRACH时机的时域起始位置和第一PRACH时机的持续时长。比如，PRACH时机的时域起始位置为第A3个时隙的第a1个符号，和PRACH时机的持续时长为A4个时隙。又比如，PRACH时机的时域起始位置为第A5个子帧，和PRACH时机的持续时长为A6个子帧。
所述第一PRACH时机的频域资源位置信息可以包含以下一个或多个：第一PRACH时机的最低频点位置、第一PRACH时机的最高频点位置、第一PRACH时机的中心频点位置、第一PRACH时机的频域范围大小。
其中，第一PRACH时机的频域范围大小，小于所述第一PRACH的频域资源的大小。第一PRACH时机的最低频点位置、中心频点位置、最高频点位置可以是以PRB、RB、Khz、Mhz中任意之一为单位。
在一种可能的实施方式中，所述第一PRACH时机的频域资源位置信息，包含第一PRACH时机的最低频点位置、第一PRACH时机的最高频点位置。所述终端设备基于第一PRACH时机的最低频点位置以及第一PRACH时机的最高频点位置，可以确定第一PRACH时机的频域资源范围。
在另一种可能的实施方式中，所述第一PRACH时机的频域资源位置信息，包含第一PRACH时机的最低频点位置和第一PRACH时机的频域范围大小。基于第一PRACH时机的最低频点位置和第一PRACH时机的频域范围大小，可以确定一个第一PRACH时机的频域资源范围。
比如，第一PRACH时机的最低频点位置为第B3个PRB，第一PRACH时机的频域范围大小包括B4个PRB。当然，上述PRACH时机的频域位置的指示中还可以采用其他单位，比如RB、KHz、MHZ等等，比如，PRACH时机的频域起始位置为B5Mhz，PRACH时机的频域范围大小可以为B6Mhz，这里不做穷举。
在又一种可能的实施方式中，所述第一PRACH时机的频域资源位置信息，包含第一PRACH时机的中心频点位置和第一PRACH时机的频域范围大小。基于第一PRACH时机的中心频点位置、第一PRACH时机的频域范围大小，可以确定一个第一PRACH时机的频域资源范围。

所述前导码索引号，具体可以指的是本次所述终端设备所使用的前导码索引号。在整个系统中每个第一PRACH时机可以对应有多个预先配置的前导码(比如可以有64个前导码)及其分别对应的索引号；网络设备可以通过在第一PRACH资源的配置信息中指示本次使用的前导码索引号，比如可以指示6、9或其他索引号，这里不做穷举；相应的，所述终端设备可以通过解析所述第一PRACH资源的配 置信息，获取本次所要使用的前导码岁引号，进而确定本次使用的前导码。需要指出的是，多个预先配置的前导码及其分别对应的索引号，可以为网络设备通过系统广播消息预先配置给终端设备的。
所述第一PRACH的周期，可以指的是每一个第一PRACH的周期的长度。周期的单位可以是时隙、符号、子帧、微秒、毫秒等等。比如，第一PRACH的周期的长度为10个时隙。需要指出的是，所述第一PRACH的周期可以是在基于前述第一PRACH的时域资源位置信息以及第一PRACH的频域资源位置信息，确定第一个周期的第一PRACH资源之后，基于该第一PRACH的周期确定一个或多个周期，并确定该一个或多个周期中各个周期的第一PRACH资源。比如，根据第一PRACH的周期可以确定各个周期的长度；基于前述第一PRACH的时域资源位置信息以及第一PRACH的频域资源位置信息，确定第一个周期的第一PRACH资源的时域资源范围为第X1～X2个时隙，频域范围为第Y1～Y2个PRB。基于各个周期的长度可以确定各个周期中第一PRACH的时域资源范围，比如周期长度为L个时隙，第二个周期中第一PRACH的时域资源范围可以为L+X1～L+X2个时隙，第二个周期中第一PRACH的频域范围可以不变同样为第Y1～Y2个PRB。
所述第一PRACH的时隙，可以指的是所述第一PRACH的发送时隙，或称为通过该第一PRACH发送随机接入前导码的发送时隙。应理解，在第一PRACH资源的配置信息中，配置了所述第一PRACH的时域资源位置信息、第一PRACH与SSB的映射关系的情况下，所述第一PRACH资源的配置信息可以不包含所述第一PRACH的时隙。或者，在第一PRACH资源的配置信息中，未配置所述第一PRACH的时域资源位置信息、未配置第一PRACH与SSB的映射关系的情况下，所述第一PRACH资源的配置信息可以包含所述第一PRACH的时隙。
所述第一PRACH的子载波间隔，可以指的是所述第一PRACH的频域资源上采用的子载波间隔。该第一PRACH的子载波间隔可以与当前系统的子载波间隔相同。或者，所述第一PRACH的子载波间隔可以为根据实际情况设置的，比如，可以为15kHZ、30Khz、60Khz、120Khz、240Khz等等，这里不做穷举。
应理解，在终端设备所接收到的WUS所携带的第一信息中，可以包含上述第一PRACH资源的配置信息的一个或多个具体内容。
进一步地，还可以包括：所述终端设备基于所述第一PRACH资源的配置信息，确定第一PRACH资源；所述终端设备在所述第一PRACH资源上进行随机接入。
前述已经说明，所述终端设备监听WUS，具体可以是：所述终端设备处于空闲态的情况下，监听所述WUS。相应的，所述终端设备基于所述WUS携带的所述第一信息中包含的所述第一PRACH资源的配置信息确定第一PRACH资源；所述终端设备在所述第一PRACH资源上进行随机接入，具体可以指的是：所述终端设备处于空闲态的情况下，基于所述WUS携带的所述第一信息中包含的所述第一PRACH资源的配置信息，确定第一PRACH资源；所述终端设备在所述第一PRACH资源上进行随机接入。
所述终端设备监听唤醒信号WUS之前，所述方法还包括：所述终端设备接收网络设备配置的第二PRACH资源的配置信息；其中，所述第二PRACH资源的配置信息，与所述第一PRACH资源的配置信息不同。
所述第二PRACH资源的配置信息，用于确定执行随机接入的第二PRACH资源；所述第二PRACH资源与所述第一PRACH资源的时域资源位置不同。也就是说，在所述终端设备中还可以获取并保存第二PRACH资源的配置信息，并且可以基于该第二PACH资源的配置信息确定用于执行随机接入的第二PRACH资源。
具体来说，所述第二PRACH资源的配置信息，用于确定第二PRACH资源；该第二PRACH资源的配置信息中可以携带的内容包括但不限于：第二PRACH的时域资源位置(比如起始位置、结束位置、持续时长中至少之一)、第二PRACH的频域资源位置(比如频域资源大小、最低频点、最高频点、中心频点中至少之一)、第二PRACH时机的位置以及数量等等。基于该第二PRACH资源的配置信息所确定的所述第二PRACH资源，至少与第一PRACH资源的时域资源位置是不同的。具体来说，该第二PRACH资源可以是当前系统配置的原PRACH资源。比如，系统为终端设备配置的第二PRACH资源的周期比较大(比如20ms)，也就是可以是第二PRACH资源的周期大于所述第一PRACH资源；和/或，第二PRACH资源的时域起始位置晚于所述第一PRACH资源的时域起始位置。这是因为，核心网的设备(比如MME)确定某一个处于空闲态的终端设备当前需要进行业务传输；该核心网的设备可以通知网络设备向处于空闲态(或非激活态)的所述终端设备发送WUS；相应的，网络设备向处于空闲态(或非激活态)的所述终端设备发送所述WUS。而这种情况下，希望该处于空闲态的终端设备能够尽快或及时的进行随机接入，从而终端设备可以尽快的进行后续的处理。但是，系统为终端设备配置的第二PRACH资源的周期比较大，若要所述终端设备处于空闲态的情况下，终端设备被WUS唤醒后若 仅基于第二PRACH资源进行随机接入，可能无法保证终端设备随机接入的及时性。因此，网络设备可以在所述WUS携带的第一信息中添加第一PRACH资源的配置信息，由于所述第一PRACH资源早于所述第一PRACH资源的时域起始位置，并且，第一PRACH资源的周期小于所述第一PRACH资源；因此，所述终端设备处于空闲态(或非激活态)的情况下，终端设备被WUS唤醒后基于第一PRACH资源可以更早或更及时的进行随机接入。
在一种可能的实施方式中，所述第一PRACH资源可以是针对竞争型的随机接入过程配置的临时性PRACH资源。旨在能够配置比当前系统配置的第二PRACH资源更早的第一PRACH资源。因此，可以在第一PRACH资源(或临时性PRACH资源)的配置信息中至少携带第一PRACH的时域资源位置信息、第一PRACH的频域资源位置信息，以使得所述终端设备可以获取与当前系统配置的第二PRACH资源不同的第一PRACH资源(或临时性PRACH资源)，进而能够尽快的发起随机接入建立RRC连接。
举例来说，所述第一PRACH资源(或临时性PRACH资源)的配置信息，可以包括：第一PRACH的时域资源位置信息，第一PRACH的频域资源位置信息，第一PRACH occasion(时机)的数量，第一PRACH与SSB的映射关系等。这里不做穷举。上述第一PRACH资源的时域资源位置信息，可以具体包含第一时域偏移；和/或，所述第一PRACH的频域资源位置信息，可以具体包含第一频域偏移。关于所述第一时域偏移以及第一频域偏移的说明与前述实施例相同，不做赘述。
在一种可能的实施方式中，所述第一PRACH资源可以为终端设备专用PRACH，使得终端设备可以执行免竞争的随机接入，以避免当终端设备使用基于竞争的随机接入时，在随机接入过程中与其他终端设备随机接入之间的干扰的问题，从而保证提升终端随机接入的成功率，加快终端RRC连接建立过程。这种实施方式中，所述WUS中携带的第一指示中的第一PRACH资源的配置信息，可以为专用PRACH资源的配置信息。举例来说，上述第一PRACH资源的配置信息可以包括：第一PRACH时机的时域资源位置信息、第一PRACH时机的频域资源位置信息、前导码索引号；该第一PRACH时机的时域资源位置信息中可以包括第一PRACH的时域资源的持续时长等。
可选地，所述第一PRACH资源的配置信息具体用于配置符合所述UE标识的终端设备。也就是，终端设备基于所述WUS中包含的UE标识，确定自身为符合所述UE标识的终端设备的情况下，可以基于该WUS唤醒第二部件，并且可以基于所述WUS的第一信息中包含的该第一PRACH资源的配置信息，确定所述第一PRACH资源；在所述第一PRACH资源上进行随机接入。其中，在所述第一PRACH资源(或临时性PRACH资源)上进行随机接入具体可以指的是，所述终端设备在所述第一PRACH资源(或临时性PRACH资源)上发起随机接入请求。关于所述WUS中包含的UE标识、所述终端设备如何确定自身是否为符合所述UE标识的终端设备的具体处理方式，在前述实施例中已经说明，因此不做重复说明。关于WUS中还可以携带比特图及其对应的唤醒终端设备的方式在前述实施例也做了详细说明，因此不再赘述。

或者，终端设备的第一部件(即WUR)在接收到该WUS之后，若确定自身符合所述UE标识的终端设备，则终端设备的第一部件(即WUR)基于所述第一PRACH资源的配置信息确定第一PRACH资源；所述终端设备的第一部件(即WUR)唤醒第二部件(即主接收机)；所述终端设备的主接收机(即第二部件)在第一PRACH资源(或临时性PRACH资源)上进行随机接入(具体可以为发起随机接入请求)。
或者，终端设备的第一部件(即WUR)在接收到该WUS之后，从该WUS中获取比特图，从所述比特图中获取所述终端设备所在的终端设备组所对应的比特位的取值；若该比特位的取值为二进制第一值，则所述终端设备可以唤醒第二部件(即主接收机)；所述终端设备的主接收机(即第二部件)在第一PRACH资源(或临时性PRACH资源)上进行随机接入(具体可以为发起随机接入请求)。
或者，终端设备的第一部件(即WUR)在接收到该WUS之后，若确定该WUS中未携带任何终端设备的标识以及终端组的标识，则所述终端设备的第一部件(即WUR)唤醒第二部件(即主接收机)；所述终端设备的第二部件(即主接收机)基于所述第一PRACH资源的配置信息确定第一PRACH资源；所述终端设备的第二部件(即主接收机)在基于第一PRACH资源(或临时性PRACH资源)的配置信息确定第一PRACH资源(或临时性PRACH资源)的情况下，在第一PRACH资源(或临时性PRACH 资源)上进行随机接入(具体可以为发起随机接入请求)。
可选地，在所述第一PRACH资源的配置信息中还可以进一步包含新的UE标识，该新的UE标识也可以为：新的UE ID、新的UE组ID、新的小区ID中之一。相应的，终端设备基于所述WUS中包含的UE标识，确定自身为符合所述UE标识的终端设备的情况下，可以基于该WUS唤醒第二部件；在基于所述第一PRACH资源的配置信息中包含的新的UE标识，确定自身为符合该UE标识的终端设备的情况下，可以使用所述WUS的第一信息中包含的该第一PRACH资源的配置信息以确定所述第一PRACH资源。还可以包括:在基于所述第一PRACH资源的配置信息中包含的新的UE标识，确定自身不为符合该UE标识的终端设备的情况下，可以不使用所述WUS的第一信息中包含的该第一PRACH资源的配置信息。
接下来针对所述第一信息中包含的目标初始BWP的配置信息，以及终端设备基于该目标初始BWP的配置信息所执行的处理进行说明：
所述目标初始BWP的配置信息，包括：所述目标初始BWP的ID，所述目标初始BWP为多个初始BWP中的一个或多个，所述多个初始BWP包括一个或多个初始上行BWP和/或一个或多个初始下行BWP，所述目标初始BWP为上行BWP和/或下行BWP。
终端设备还可以预先保存多个初始BWP的配置及其索引号，具体的，所述终端设备可以预先保存一个或多个初始上行BWP的配置及其索引号和/或一个或多个初始下行BWP的配置及其索引号。
上述多个初始BWP的配置及其索引号可以为终端设备根据协议预先设置的，或者可以是从网络设备获取的。关于多个初始BWP的配置及其索引号为从网络设备获取的方式中，具体获取方式可以为：所述终端设备接收第二信息；所述第二信息中包括多个初始BWP的配置及其索引号。所述第二信息可以为在所述终端设备处于RRC连接态的情况下，接收所述网络设备发送的第二信息，该第二信息可以携带在系统广播消息、RRC信令、MAC CE中的任意之一中，这里不对其进行穷举。
上述目标初始BWP的配置信息中包含的目标初始BWP的ID，还可以为目标初始BWP的索引号。其中，所述目标初始BWP可以包括上行BWP和/或下行；相应的，BWP目标初始BWP的ID(或索引号)，可以仅包含上行BWP的ID(或索引号)，或者仅包含下行BWP的ID(或索引号)，或者包含上行BWP的ID(或索引号)以及下行BWP的ID(或索引号)。
在目标初始BWP的配置信息包含不同内容以及终端设备预先配置的初始BWP不同的情况下，终端设备确定目标初始BWP的方式可以分多种情况来说：
情况一、所述终端设备预先配置的初始BWP，包括一个初始下行BWP，以及多个初始上行BWP。所述目标初始BWP的配置信息中包含的目标初始BWP的ID可以为上行BWP的ID。
也就是说，这种情况下，由于终端设备预先配置了一个初始下行BWP，因此，所述终端设备可以默认使用该初始下行BWP作为所述目标初始BWP中的下行BWP。在所述目标初始BWP的配置信息中不需要指示其中包含的目标初始BWP的一个ID为上行BWP还是下行BWP，终端设备可以默认该目标初始BWP的一个ID为一个上行BWP的ID。
举例来说，若WUS中携带的第一信息中的目标初始BWP的配置信息中仅包含上行BWP的ID，则终端设备可以基于上行BWP的ID确定所述目标初始BWP中的上行BWP，然后将终端设备预先配置的初始下行BWP直接作为所述目标初始BWP中的下行BWP。
情况二、所述终端设备预先配置的初始BWP，包括一个初始上行BWP，以及多个初始下行BWP。所述目标初始BWP的配置信息中包含的目标初始BWP的ID可以为下行BWP的ID。
也就是说，这种情况下，由于终端设备预先配置了一个初始上行BWP，因此，所述终端设备可以默认使用该初始上行BWP作为所述目标初始BWP中的上行BWP。在所述目标初始BWP的配置信息中不需要指示其中包含的目标初始BWP的一个ID为上行BWP还是下行BWP，终端设备可以默认该目标初始BWP的一个ID为一个下行BWP的ID。
举例来说，若WUS中携带的第一信息中的目标初始BWP的配置信息中仅包含下行BWP的ID，则终端设备可以基于下行BWP的ID确定所述目标初始BWP中的下行BWP，然后将终端设备预先配置的一个初始上行BWP直接作为所述目标初始BWP中的上行BWP。
情况三、所述终端设备预先配置的初始BWP，包括多个初始上行BWP，以及多个初始下行BWP。通常所述多个初始上行BWP与所述多个初始下行BWP的ID具备对应关系。其中，对应关系可以指的是初始下行BWP和初始上行BWP使用相同的ID(或索引号)；比如，所述终端设备预先配置的初始BWP，包括2个初始上行BWP，以及2个初始下行BWP；2个初始上行BWP的ID分别为初始上行BWP-0、初始上行BWP-1，2个初始下行BWP的ID分别为初始下行BWP-0、初始下行BWP-1。或者，该对应关系还可以指的是预先设置的初始下行BWP和初始上行BWP的ID的匹配关系；比如，所述终端设备预先配置的初始BWP，包括2个初始上行BWP，以及2个初始下行BWP；2个初始上行BWP 的ID分别为初始上行BWP-0、初始上行BWP-1，2个初始下行BWP的ID分别为初始下行BWP-3、初始下行BWP-2；其中，初始上行BWP-0与初始下行BWP-2之间预先设置了对应关系(即两者匹配)，初始上行BWP-1与初始下行BWP-3之间预先设置了对应关系(即两者匹配)。
由于终端设备预先配置了一个初始上行BWP以及多个初始上行BWP与所述多个初始下行BWP的ID具备对应关系。因此，所述目标初始BWP的配置信息中可以包含一个目标初始BWP的ID，该目标初始BWP的ID可以为下行BWP的ID。举例来说，若WUS中携带的第一信息中的目标初始BWP的配置信息中仅包含下行BWP的ID，则终端设备可以基于下行BWP的ID确定所述目标初始BWP中的下行BWP，然后终端设备根据预先配置的多个初始上行BWP与所述多个初始下行BWP的ID的对应关系，基于该目标初始BWP中的下行BWP的ID确定对应的上行BWP。
情况四、所述终端设备预先配置的初始BWP，包括多个初始上行BWP，以及多个初始下行BWP。与前述情况三不同在于，本情况中，终端设备中可以不预先配置所述多个初始上行BWP与所述多个初始下行BWP的ID的对应关系。因此，所述目标初始BWP的配置信息中可以包含多个目标初始BWP的ID。
可选的，所述目标初始BWP的配置信息中可以包含两个目标初始BWP的ID。该两目标初始BWP的ID可以包括下行BWP的ID以及上行BWP的ID。
举例来说，若WUS中携带的第一信息中的目标初始BWP的配置信息包括了下行BWP的ID以及上行BWP的ID，则终端设备可以基于下行BWP的ID确定所述目标初始BWP中的下行BWP，基于下行BWP的ID确定所述目标初始BWP中的上行BWP。
可选的，所述方法还可以包括：所述终端设备基于所述WUS携带的所述第一信息中包含的所述目标初始BWP的配置信息确定目标初始BWP，在所述目标初始BWP上进行初始接入。具体的：所述终端设备的第一部件在接收到WUS的情况下，唤醒所述终端设备的第二部件；所述终端设备的第二部件基于所述目标初始BWP的配置信息确定目标初始BWP，在所述目标初始BWP上进行初始接入。或者，所述终端设备的第一部件在接收到WUS的情况下，基于所述WUS中携带的相关指示信息，确定唤醒所述终端设备的第二部件；所述终端设备的第二部件在基于所述目标初始BWP的配置信息确定目标初始BWP的情况下，在所述目标初始BWP上进行初始接入。
上述初始接入可以包括小区搜索和随机接入等过程。通过小区搜索可以使得终端设备与网络设备获得下行同步，然后终端设备可以进行随机接入。比如，在所述目标初始BWP上进行初始接入，可以为：所述终端设备进行小区搜索、完成与网络设备的下行同步后，所述终端设备可以在所述上行BWP发送随机接入请求(即msg1)，在该下行BWP上接收网络设备发送的随机接入响应(即msg2)；在所述目标初始BWP还包含上行BWP的情况下，所述终端设备在所述上行BWP上传输RRC消息(即msg3)，用于通知网络设备随机接入过程的触发原因；所述终端设备在所述下行BWP上接收竞争冲突解决信息(即msg4)。
可选地，所述目标初始BWP的配置信息具体用于配置符合所述UE标识的终端设备。也就是，终端设备基于所述WUS中包含的UE标识，确定自身为符合所述UE标识的终端设备的情况下，所述终端设备的第二部件基于所述目标初始BWP的配置信息确定目标初始BWP，在所述目标初始BWP上进行初始接入。关于所述WUS中包含的UE标识、所述终端设备如何确定自身是否为符合所述UE标识的终端设备的具体处理方式，在前述实施例中已经说明，因此不做重复说明。关于WUS中还可以携带比特图及其对应的唤醒终端设备的方式在前述实施例也做了详细说明，因此不再赘述。
或者，在所述目标初始BWP的配置信息中还可以进一步包含新的UE标识，该新的UE标识也可以为：新的UE ID、新的UE组ID、新的小区ID中之一。相应的，终端设备基于所述WUS中包含的UE标识，确定自身为符合所述UE标识的终端设备的情况下，可以基于该WUS唤醒第二部件；在基于所述目标初始BWP的配置信息包含的新的UE标识，确定自身为符合该UE标识的终端设备的情况下，所述终端设备的第二部件基于所述目标初始BWP的配置信息确定目标初始BWP，在所述目标初始BWP上进行初始接入。另外，还可以包括：若基于所述目标初始BWP的配置信息包含的新的UE标识，确定自身为不符合该UE标识的终端设备的情况下，所述终端设备的第二部件不基于所述目标初始BWP的配置信息确定目标初始BWP。
可选地，本实施例提供的方式中，所述终端设备为降低能力(RedCap，Reduced Capability)终端。这是由于，通常其他类型的终端设备，系统为其配置一个初始BWP；而在降低能力(RedCap，Reduced Capability)终端中，由于其带宽更小(通常为20MHz小于传统的100MHz)、天线数量更少、采用简单的调制方式(比如64QAM)、采用半双工FDD等，因此系统会为其预先配置多个初始BWP。通过采用本实施例提供的方案，可以通过预先配置多个初始BWP，以保证网络设备指示不同终端设备进行初始接入的时候，可以仅通过WUS中的第一信息指示目标初始BWP的ID，即可确定本次所要使用的上行 BWP和/或下行BWP，进而在该上行BWP和/或下行BWP上进行初始接入的处理，从而可以实现负载分流或负载均衡的效果，另外，由于采用这样的方式不需要终端设备侧保存过多的交互过程中产生的信息，因此可以减少资源碎片，更加适用于窄带RedCap终端。
接下来针对所述第一信息中包含的同步信号的配置信息，以及终端设备的相关处理进行详细说明：
所述同步信号的配置信息，可以包括以下一个或多个：同步信号的发送周期；同步信号的时域资源位置信息；同步信号的频域资源位置信息；同步信号的天线端口；同步信号的发送波束。

所述同步信号的发送周期，可以比当前系统中的同步信号原发送周期小，也就是说，可以加密(加多)发送所述同步信号。所述同步信号的发送周期具体可以根据实际情况进行配置，比如可以是1ms、2ms或更长或更短，这里不做穷举。

举例来说，同步信号的时域资源位置信息中直接包含所述同步信号的时域资源位置以及所述同步信号的时域资源的持续时长。其中，所述同步信号的时域资源的时域位置，包括：所述同步信号的时域资源的时域起始位置，或所述同步信号的时域资源的时域结束位置。
所述终端设备可以基于所述同步信号的时域起始位置以及所述同步信号的时域资源的持续时长，确定同步信号的时域资源的时域终止位置；基于所述同步信号的时域资源的时域起始位置，和所述同步信号的时域资源的时域结束位置，确定所述同步信号的时域范围。
可选的，所述同步信号的时域资源位置信息，包括以下一个或多个：第二时域偏移，所述第二时域偏移用于表示所述WUS的接收时间与所述同步信号的时域资源的时域位置之间的偏移；所述同步信号的时域资源的持续时长。
所述同步信号的时域资源的时域位置，可以包括：所述同步信号的时域资源的时域起始位置，和/或，所述同步信号的时域资源的时域结束位置。
由于所述WUS可以占用一段时域资源，本实施例中，可以指定所述WUS所占用的一段时域资源中的一个时间(或一个时刻)作为该WUS的接收时间。所述WUS的接收时间，可以包括：所述WUS的起始接收时间、或者、所述WUS的接收完成时间。应理解，所述WUS的接收时间还可以为所述WUS所占用的时域资源中的其他时间，比如可以为所述WUS所占用的时域资源的中点时间等等，只要所述终端设备与所述网络设备双方采用相同的WUS的接收时间即可。
所述第二时域偏移，可以包括一个数值或多个数值。
举例来说，在第二时域偏移中包含一个数值，比如第七数值；该第七数值用于表示所述WUS的接收时间与所述同步信号的时域资源的时域起始位置之间的偏移；或者，用于表示所述WUS的接收时间与所述同步信号的时域资源的时域结束位置之间的偏移。该第二时域偏移的单位可以是时隙、符号、帧、子帧、毫秒等任意至少之一。这种实施方式中，所述同步信号的时域资源位置信息还可以包括：所述同步信号的时域资源的持续时长。
所述终端设备可以确定所述同步信号的时域资源的时域起始位置为所述WUS的起始接收时间延迟第二时域偏移之后的位置；基于前述同步信号的时域资源的时域起始位置，加同步信号的时域资源的持续时长，得到同步信号的时域资源的时域结束位置；将同步信号的时域资源的时域起始位置以及时域结束位置之间的范围，作为所述同步信号的时域资源的具体位置。
举例来说，所述第二时域偏移，可以包括多个数值，比如包含两个数值，分别为第八数值和第九数值；该第八数值用于表示所述WUS的接收时间与所述同步信号的时域资源的时域起始位置之间的偏移；第九数值用于表示所述WUS的接收时间与所述同步信号的时域资源的时域结束位置之间的偏移。该第二时域偏移的单位可以是时隙、符号、帧、子帧、毫秒等任意至少之一。其中，第八数值小于第九数值。
所述终端设备可以确定所述同步信号的时域资源的时域起始位置为所述WUS的起始接收时间延迟第八数值之后的位置；确定所述同步信号的时域资源的时域结束位置为所述WUS的起始接收时间延迟第九数值之后的位置；将同步信号的时域资源的时域起始位置以及时域结束位置之间的范围，作为所述同步信号的时域资源的具体位置。
可选的，所述同步信号的频域资源位置信息，包含以下一个或多个：所述同步信号的频域资源的第二类频点的位置；所述同步信号的频域资源的大小。
所述同步信号的频域资源的第二类频点，包括以下一个或多个：所述同步信号的频域资源的最低频点；所述同步信号的频域资源的最高频点；所述同步信号的频域资源的中心频点。该第二类频点的具体位置还可以根据实际情况的不同而不同，只要终端设备与网络设备双方预先确定采用相同的参考频点即可。
举例来说，所述同步信号的频域资源的第二类频点的位置包含有所述同步信号的频域资源最低频点、所述同步信号的频域资源最高频点；相应的，所述终端设备可以将所述同步信号的频域资源的最低频点以及最高频点之间的频域范围，直接作为所述同步信号的频域范围。举例来说，所述同步信号的频域资源的第二类频点的位置可以仅包含一个频点；则所述同步信号的频域资源位置信息还会包含所述同步信号的频域资源的大小。比如，所述同步信号的频域资源的第二类频点的位置仅为中心频点；所述终端设备可以基于所述同步信号的频域资源的中心频点的位置，以及同步信号的频域资源的大小，确定所述同步信号的频域范围；该频域范围指的是所述同步信号的最低频点至所述同步信号的最高频点之间的范围。
可选的，所述同步信号的频域资源位置信息，包含以下一个或多个：第二频域偏移，所述第二时域偏移用于表示所述WUS的频域位置与所述同步信号的频域资源的第二类频点之间的偏移；所述同步信号的频域资源的大小。
所述第二频域偏移的单位可以为PRB、RB、Khz、Mhz中任意之一。
同样的，所述同步信号的频域资源的第二类频点，包括以下一个或多个：所述同步信号的频域资源的最低频点；所述同步信号的频域资源的最高频点；所述同步信号的频域资源的中心频点。

该第二频域偏移的单位，可以为PRB、RB、Khz、Mhz等等中任意之一。所述第二频域偏移可以包括一个或多个数值。
在一种可能的实施方式中，在所述第二频域偏移包括一个数值，将该数值称为第十数值。该第二频域偏移值(即第十数值)可以用于表示所述同步信号的频域资源的一个第二类频点，与所述WUS的一个频域位置之间的相对频域偏移。这种实施方式中，所述同步信号的频域资源位置信息中还可以包括：同步信号的频域资源的大小。
举例来说，以所述同步信号的频域资源的第二类频点为最低频点、所述WUS的频域位置为WUS占用的频域资源中的中心频点为例；所述终端设备在监听到WUS的情况下，基于所述WUS占用的频域资源中的中心频点的位置增加(或减少)第十数值，得到所述同步信号的频域资源的最低频点的位置。所述终端设备可以基于所述同步信号的频域资源的最低频点的位置，加同步信号的频域资源的大小，得到同步信号的频域资源的最高频点的位置；将同步信号的频域资源的最高频点以及最低频点之间的范围，作为所述同步信号的频域资源的具体范围。再举例来说，以所述同步信号的频域资源的第二类频点为中心频点、所述WUS的频域位置为WUS占用的频域资源中的最高频点为例；所述终端设备在监听到WUS的情况下，基于所述WUS的最高频点的位置增加(或减少)第四数值，得到所述同步信号的频域资源的中心频点的位置。所述终端设备可以基于所述同步信号的频域资源的中心频点的位置，加同步信号的频域资源的大小的1/2，得到同步信号的频域资源的最高频点的位置；基于所述同步信号的频域资源的中心频点的位置，减去同步信号的频域资源的大小的1/2，得到同步信号的频域资源的最低频点的位置；将同步信号的频域资源的最高频点以及最低频点之间的范围，作为所述同步信号的频域资源的具体范围。
在一种可能的实施方式中，在所述第二频域偏移包括两个数值，分别为第十一数值和第十二数值；其中，第十一数值可以用于表示所述同步信号的频域资源的一个第二类频点，与所述WUS的一个频域位置之间的相对频域偏移；以及第十二数值，用于表示所述同步信号的频域资源的另一个第二类频点，与所述WUS的一个频域位置之间的相对频域偏移。这种实施方式中，所述同步信号的频域资源位置信息中可以不包括第一PRACH的频域资源的大小。
举例来说，以所述同步信号的频域资源的一个第二类频点为最低频点、另一个第二类频点为最高频点、所述WUS的频域位置为WUS占用的频域资源中的中心频点为例；所述终端设备在监听到WUS的情况下，基于所述WUS占用的频域资源中的中心频点的位置减少第十一数值，得到所述同步信号的 频域资源的最低频点的位置；基于所述WUS占用的频域资源中的中心频点的位置增加第十二数值，得到所述同步信号的频域资源的最高频点的位置；将同步信号的频域资源的最高频点以及最低频点之间的范围，作为所述同步信号的频域资源的具体范围。
这种方式中，所述终端设备可以基于所述第二频域偏移，确定所述同步信号的频域资源位置，基于所述同步信号的频域资源位置，确定同步信号的频域范围。具体可以为：所述终端设备基于所述第二频域偏移、以及WUS的频域位置，确定所述同步信号的频域资源的参考频点的位置，基于所述同步信号的参考频点的位置，确定同步信号的频域范围。比如，所述终端设备基于WUS的频域位置(比如最高频点)增加或减少所述第二频域偏移，得到所述同步信号的频域资源的参考频点(比如最低频点)的位置，然后基于所述同步信号的参考频点(比如最低频点)的位置以及同步信号预设频域资源大小，确定同步信号的频域范围。当然，还可以存在其他的确定同步信号的频域范围示例，只是不做穷举。
所述同步信号的天线端口、同步信号的发送波束可以由网络设备基于实际发送的情况来确定，这里不对其进行限定。
还需要指出，前述同步信号的配置信息，可以包括以上全部内容，或者可以仅包含其中部分。在所述同步信号的配置信息仅包含其中部分的情况下，可以包含第三配置信息以及第四配置信息；或者，可以包括同步信号的发送周期以及所述第四配置信息等等，这里不做穷举。
进一步地，还可以包括：所述终端设备基于所述同步信号的配置信息确定同步信号；所述终端设备基于所述同步信号进行时频同步。另外，还可以包括：所述终端设备在完成时频同步的情况下，进行随机接入。上述时频同步具体可以指的是所述终端设备与网络设备完成下行时频同步。
可选的，上述同步信号的配置信息具体用于配置符合所述UE标识的终端设备。因此，所述WUS中还会可以携带UE标识，所述UE标识为UE ID、或UE组ID、或小区ID。或者，所述WUS中还可以携带比特图。关于终端设备基于WUS中携带的UE标识(或比特图)判断自身是否为符合UE标识的终端设备的处理方式，在前述实施例中已经描述，不做赘述。
可选地，所述同步信号的配置信息具体用于配置符合所述UE标识的终端设备。也就是，终端设备基于所述WUS中包含的UE标识，确定自身为符合所述UE标识的终端设备的情况下，所述终端设备的第二部件基于所述同步信号的配置信息确定同步信号；基于所述同步信号进行时频同步。
或者，在所述同步信号的配置信息中还可以进一步包含新的UE标识，该新的UE标识也可以为：新的UE ID、新的UE组ID、新的小区ID中之一。相应的，终端设备基于所述WUS中包含的UE标识，确定自身为符合所述UE标识的终端设备的情况下，可以基于该WUS唤醒第二部件；在基于所述同步信号的配置信息包含的新的UE标识，确定自身为符合该新的UE标识的终端设备的情况下，所述终端设备的第二部件基于所述同步信号的配置信息确定同步信号；基于所述同步信号进行时频同步。另外，还可以包括：若基于所述目标初始BWP的配置信息包含的新的UE标识，确定自身为不符合该UE标识的终端设备的情况下，所述终端设备的第二部件不基于所述同步信号的配置信息确定同步信号。
上述同步信号的配置信息，主要是用于终端设备(终端设备的第二部件)唤醒后，由该终端设备的第二部件或称为主接收机进行数据收发。由于通常终端设备在与网络设备进行数据收发之前，终端设备的主接收机需使用同步信号获得时频同步。因为，为了优化终端的时频同步过程，除了网络正常发送的同步信号(比如SSB信号)之外，可以额外加密发送同步信号(比如SSB信号)或额外发送其他参考信号(如TRS，或CSI-RS)，使得终端可以在短时间内接收到更多的同步信号，用于加快终端完成时频同步过程。
最后需要说明的是，在所述第一信息中包含的内容不同的情况下，所述终端设备执行的处理也可以不同，在以上实施例中，针对第一信息分别包含第一PRACH资源的配置信息、目标初始BWP的配置信息、同步信号的配置信息的情况下，所述终端设备进行的相关处理进行了相关说明。在实际处理中，第一信息还可以包含上述两个或全部信息，所述终端设备所执行的处理也可以随之进行调整，下面举例来进行说明：

第二示例、所述第一信息中包含第一PRACH资源的配置信息和同步信号的配置信息。
所述终端设备在基于所述第一PRACH资源的配置信息确定所述第一PRACH资源，并且基于所述同步信号的配置信息完成时频同步的情况下，在所述第一PRACH资源上进行随机接入(具体可以为在所述第一PRACH资源上发起随机接入请求)。
第三示例、所述第一信息中包含第一PRACH资源的配置信息、目标初始BWP的配置信息、同步信号的配置信息。
所述终端设备在基于所述目标初始BWP的配置信息确定目标初始BWP，基于所述第一PRACH资源的配置信息确定所述目标初始BWP上的第一PRACH资源，并且基于所述同步信号的配置信息确定同步信号；在基于同步信号完成时频同步的情况下，在第一PRACH资源上发起随机接入请求，并在所述目标初始BWP上进行初始接入中的后续随机接入处理。
可见，通过采用上述方案，终端设备可以监听WUS，该WUS可以用于唤醒终端设备；该WUS中携带的可以用于所述终端设备在唤醒后执行的操作。如此，就可以使得终端设备基于接收到WUS唤醒，基于该WUS中的第一信息及时的执行唤醒后的操作，这样就可以缩短业务传输的时延，进而提升系统的处理效率。
图6是根据本申请第二方面实施例的通信方法的示意性流程图。该方法可选地可以应用于图1所示的系统，但并不仅限于此。该方法包括以下内容的至少部分内容。

所述WUS为UE专属的；或者所述WUS为UE组共享的，所述UE组可以是包含所述终端设备的UE组；或者所述WUS为小区专用的，所述小区可以为所述终端设备所在的服务小区。因此，所述WUS还可以包括：UE标识，所述UE标识为UE ID或UE组UD或小区ID。需要指出的是，所述UE标识可以包含在所述WUS中的第一信息中，或者所述UE标识可以不包含的WUS的第一信息中。本实施例不对所述UE标识在所述WUS中的具体信息位置进行限定。
其中，所述UE ID可以指的是终端设备的标识，可以为终端设备的唯一标识，比如，可以为以下任意之一：可以采用临时移动用户识别码(TMSI，Temporary Mobile Subscriber Identity)、国际移动用户识别码(IMSI，International Mobile Subscriber Identity)、I-RNTI(Inactive Radio Network Temporary Identifier，非激活无线网络临时标识)。所述UE组可以是一个或多个终端设备所组成的；系统中可以配置一个或多个UE组，并且系统中为该一个或多个UE组中不同的UE组分配了不同的ID，以唯一区分不同的UE组。所述小区ID可以是系统中包含的一个或多个小区分别对应的ID。所述WUS具体用于唤醒符合所述UE标识的终端设备。
可选的，该UE标识可以替换为比特图；在该比特图中的某一个比特位的取值可以用于表示是否唤醒唤醒对应的终端设备或UE组；举例来说，第一值表示唤醒所述终端设备，第二值表示不唤醒所述终端设备或UE组；第一值与第二值不同，比如，第一值为1、第二值为0，或者与之相反。

在所述第一时域偏移包括两个或更多数值时，所述第一PRACH的时域资源位置信息中，可以不包含第一PRACH的时域资源的持续时长。

所述前导码索引号，具体可以指的是本次所述终端设备所使用的前导码索引号。在整个系统中每个第一PRACH时机可以对应有多个预先配置的前导码(比如可以有64个前导码)及其分别对应的索引号；网络设备可以通过在第一PRACH资源的配置信息中指示本次使用的前导码索引号。
所述第一PRACH的周期，可以指的是每一个第一PRACH的周期的长度。周期的单位可以是时隙、符号、子帧、微秒、毫秒等等。需要指出的是，所述第一PRACH的周期可以是在基于前述第一PRACH的时域资源位置信息以及第一PRACH的频域资源位置信息，确定第一个周期的第一PRACH资源之后，基于该第一PRACH的周期确定一个或多个周期，并确定该一个或多个周期中各个周期的第一PRACH资源。
所述第一PRACH的时隙，可以指的是所述第一PRACH的发送时隙，或称为通过该第一PRACH发送随机接入前导码的发送时隙。应理解，在第一PRACH资源的配置信息中，配置了所述第一PRACH的时域资源位置信息、第一PRACH与SSB的映射关系的情况下，所述第一PRACH资源的配置信息可以不包含所述第一PRACH的时隙。或者，在第一PRACH资源的配置信息中，未配置所述第一PRACH的时域资源位置信息、未配置第一PRACH与SSB的映射关系的情况下，所述第一PRACH资源的配置信息可以包含所述第一PRACH的时隙。
所述第一PRACH的子载波间隔，可以指的是所述第一PRACH的频域资源上采用的子载波间隔。该第一PRACH的子载波间隔可以与当前系统的子载波间隔相同。或者，所述第一PRACH的子载波间隔可以为根据实际情况设置的，比如，可以为15kHZ、30Khz、60Khz、120Khz、240Khz等等，这里不做穷举。
应理解，在终端设备所接收到的WUS所携带的第一信息中，可以包含上述第一PRACH资源的配置信息的一个或多个具体内容。
所述网络设备发送WUS之前，所述方法还包括：所述网络设备为终端设备配置第二PRACH资源 的配置信息；其中，所述第二PRACH资源的配置信息，与所述第一PRACH资源的配置信息不同。
所述第二PRACH资源的配置信息，用于确定执行随机接入的第二PRACH资源；所述第二PRACH资源与所述第一PRACH资源的时域资源位置不同。
具体来说，所述第二PRACH资源的配置信息，用于确定第二PRACH资源；该第二PRACH资源的配置信息中可以携带的内容包括但不限于：第二PRACH的时域资源位置(比如起始位置、结束位置、持续时长中至少之一)、第二PRACH的频域资源位置(比如频域资源大小、最低频点、最高频点、中心频点中至少之一)、第二PRACH时机的位置以及数量等等。
基于该第二PRACH资源的配置信息所确定的所述第二PRACH资源，至少与第一PRACH资源的时域资源位置是不同的。具体来说，该第二PRACH资源可以是当前系统配置的原PRACH资源。比如，系统为终端设备配置的第二PRACH资源的周期比较大(比如20ms)，也就是可以是第二PRACH资源的周期大于所述第一PRACH资源；和/或，第二PRACH资源的时域起始位置晚于所述第一PRACH资源的时域起始位置。这是因为，核心网的设备(比如MME)确定某一个处于空闲态(或非激活态)的终端设备当前需要进行业务传输；该核心网的设备可以通知网络设备向处于空闲态(或非激活态)的所述终端设备发送WUS；相应的，网络设备向处于空闲态(或非激活态)的所述终端设备发送所述WUS。而这种情况下，希望该处于空闲态的终端设备能够尽快或及时的进行随机接入，从而终端设备可以尽快的进行后续的处理。但是，系统为终端设备配置的第二PRACH资源的周期比较大，若要所述终端设备处于空闲态的情况下，终端设备被WUS唤醒后若仅基于第二PRACH资源进行随机接入，可能无法保证终端设备随机接入的及时性。因此，网络设备可以在所述WUS携带的第一信息中添加第一PRACH资源的配置信息，由于所述第一PRACH资源早于所述第一PRACH资源的时域起始位置，并且，第一PRACH资源的周期小于所述第一PRACH资源；因此，所述终端设备处于空闲态(或非激活态)的情况下，终端设备被WUS唤醒后基于第一PRACH资源可以更早或更及时的进行随机接入。
在一种可能的实施方式中，所述第一PRACH资源可以是针对竞争型的随机接入过程配置的临时性PRACH资源。旨在能够配置比当前系统配置的第二PRACH资源更早的第一PRACH资源。因此，可以在第一PRACH资源(或临时性PRACH资源)的配置信息中至少携带第一PRACH的时域资源位置信息、第一PRACH的频域资源位置信息，以使得所述终端设备可以获取与当前系统配置的第二PRACH资源不同的第一PRACH资源(或临时性PRACH资源)，进而能够尽快的发起随机接入建立RRC连接。
在一种可能的实施方式中，所述第一PRACH资源可以为终端设备专用PRACH，使得终端设备可以执行免竞争的随机接入，以避免当终端设备使用基于竞争的随机接入时，在随机接入过程中与其他终端设备随机接入之间的干扰的问题，从而保证提升终端随机接入的成功率，加快终端RRC连接建立过程。这种实施方式中，所述WUS中携带的第一指示中的第一PRACH资源的配置信息，可以为专用PRACH资源的配置信息。
可选地，所述第一PRACH资源的配置信息具体用于配置符合所述UE标识的终端设备。
一种情况中，核心网的设备(比如MME)可以确定某一个终端设备当前需要进行业务传输；该核心网的设备可以通知网络设备向所述终端设备发送WUS；相应的，所述网络设备向该终端设备发送WUS，所述WUS中可以携带所述UE标识以及第一信息，该第一信息中可以包括第一PRACH资源(或临时性PRACH资源)的配置信息。
又一种情况中，可选地，在所述第一PRACH资源的配置信息中还可以进一步包含新的UE标识，该新的UE标识也可以为：新的UE ID、新的UE组ID、新的小区ID中之一。比如，核心网的设备可以确定一个终端组中的一个或多个终端设备需要进行业务传输；该核心网的设备可以通知网络设备向所述终端组发送WUS；相应的，所述网络设备向该终端组的终端设备发送WUS，所述WUS中可以携带所述UE标识以及第一信息，该第一信息中可以包括第一PRACH资源(或临时性PRACH资源)的配置信息，该第一PRACH资源的配置信息中还可以包含新的UE标识。
接下来针对所述第一信息中包含的目标初始BWP的配置信息进行说明：
所述目标初始BWP的配置信息，包括：所述目标初始BWP的ID，所述目标初始BWP为多个初始BWP中的一个或多个，所述多个初始BWP包括一个或多个初始上行BWP和/或一个或多个初始下行BWP，所述目标初始BWP为上行BWP和/或下行BWP。
这种方式中，还可以包括：所述网络设备发送第二信息；所述第二信息中包括多个初始BWP的配置及其索引号。
上述目标初始BWP的配置信息中包含的目标初始BWP的ID，还可以为目标初始BWP的索引号。其中，所述目标初始BWP可以包括上行BWP和/或下行；相应的，BWP目标初始BWP的ID(或索引号)，可以仅包含上行BWP的ID(或索引号)，或者仅包含下行BWP的ID(或索引号)，或者包含上行BWP的ID(或索引号)以及下行BWP的ID(或索引号)。
在目标初始BWP的配置信息包含不同内容以及终端设备预先配置的初始BWP的不同情况分别进行说明：
情况一、所述终端设备预先配置的初始BWP，包括一个初始下行BWP，以及多个初始上行BWP。所述目标初始BWP的配置信息中包含的目标初始BWP的ID可以为上行BWP的ID。
情况二、所述终端设备预先配置的初始BWP，包括一个初始上行BWP，以及多个初始下行BWP。所述目标初始BWP的配置信息中包含的目标初始BWP的ID可以为下行BWP的ID。
情况三、所述终端设备预先配置的初始BWP，包括多个初始上行BWP，以及多个初始下行BWP。通常所述多个初始上行BWP与所述多个初始下行BWP的ID具备对应关系。其中，对应关系可以指的是初始下行BWP和初始上行BWP使用相同的ID(或索引号)。或者，该对应关系还可以指的是预先设置的初始下行BWP和初始上行BWP的ID的匹配关系。由于终端设备预先配置了一个初始上行BWP以及多个初始上行BWP与所述多个初始下行BWP的ID具备对应关系。因此，所述目标初始BWP的配置信息中可以包含一个目标初始BWP的ID，该目标初始BWP的ID可以为下行BWP的ID。
情况四、所述终端设备预先配置的初始BWP，包括多个初始上行BWP，以及多个初始下行BWP。与前述情况三不同在于，本情况中，终端设备中可以不预先配置所述多个初始上行BWP与所述多个初始下行BWP的ID的对应关系。因此，所述目标初始BWP的配置信息中可以包含多个目标初始BWP的ID。
可选的，所述目标初始BWP的配置信息中可以包含两个目标初始BWP的ID。该两目标初始BWP的ID可以包括下行BWP的ID以及上行BWP的ID。
可选地，所述目标初始BWP的配置信息具体用于配置符合所述UE标识的终端设备。
可选地，在所述目标初始BWP的配置信息中还可以进一步包含新的UE标识，该新的UE标识也可以为：新的UE ID、新的UE组ID、新的小区ID中之一。相应的，终端设备基于所述WUS中包含的UE标识，确定自身为符合所述UE标识的终端设备的情况下，可以基于该WUS唤醒第二部件；在基于所述目标初始BWP的配置信息包含的新的UE标识，确定自身为符合该UE标识的终端设备的情况下，所述终端设备的第二部件基于所述目标初始BWP的配置信息确定目标初始BWP，在所述目标初始BWP上进行初始接入。另外，还可以包括：若基于所述目标初始BWP的配置信息包含的新的UE标识，确定自身为不符合该UE标识的终端设备的情况下，所述终端设备的第二部件不基于所述目标初始BWP的配置信息确定目标初始BWP。
可选地，本实施例提供的方式中，所述终端设备为降低能力(RedCap，Reduced Capability)终端。这是由于，通常其他类型的终端设备，系统为其配置一个初始BWP；而在降低能力(RedCap，Reduced Capability)终端中，由于其带宽更小(通常为20MHz小于传统的100MHz)、天线数量更少、采用简单的调制方式(比如64QAM)、采用半双工FDD等，因此系统会为其预先配置多个初始BWP。通过采用本实施例提供的方案，可以通过预先配置多个初始BWP，以保证网络设备指示不同终端设备进行初始接入的时候，可以仅通过WUS中的第一信息指示目标初始BWP的ID，即可确定本次所要使用的上行BWP和/或下行BWP，进而在该上行BWP和/或下行BWP上进行初始接入的处理，从而可以实现负载分流或负载均衡的效果，另外，由于采用这样的方式不需要终端设备侧保存过多的交互过程中产生的信息，因此可以减少资源碎片，更加适用于窄带RedCap终端。
接下来针对所述第一信息中包含的同步信号的配置信息进行说明：
所述同步信号的配置信息，可以包括以下一个或多个：同步信号的发送周期；同步信号的时域资源位置信息；同步信号的频域资源位置信息；同步信号的天线端口；同步信号的发送波束。
