Description

一种寻呼方法、终端设备以及网络设备
本申请要求于2018年11月2日提交中国专利局、申请号为201811302859.2、发明名称为“一种寻呼方法、终端设备以及网络设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其涉及一种寻呼方法、终端设备以及网络设备。
背景技术
在第三代合作伙伴计划(3rd generation partnership project，3GPP)中，例如在长期演进(long term evolution，LTE)系统中，网络设备可以向空闲状态(idle)和连接状态(connected)的用户设备(user equipment，UE)发送寻呼消息(paging)。寻呼过程可以由核心网触发或者由基站(eNodeB)触发，该寻呼消息用于向处于空闲态的UE发送呼叫请求，或者用于通知系统信息更新，以及通知UE接收地震海啸预警信息(earthquake and tsunami warning system，ETWS)以及商用移动预警服务(commercial mobile alert system，CMAS)等信息。
eNodeB接收到核心网的寻呼消息后，解读其中的内容，得到该UE的跟踪区域标识(tracking area identity，TAI)列表(List)，并在其下属于列表中跟踪区的小区进行空口的寻呼。寻呼消息中的核心网域(CN Domain)指示不会在eNodeB解码，而是被传递到UE。eNodeB收到核心网的寻呼消息之后，将寻呼时机(paging occasion，PO)相同的UE的寻呼汇总成一条寻呼消息，通过寻呼信道传输给相关UE，UE通过系统消息收到的寻呼参数，结合自身的国际移动用户识别码(international mobile subscriber identification number，IMSI)计算寻呼时机，在相应的时间接收寻呼消息。
为了达到减少UE功耗的目的，UE使用非连续接收(discontinuous reception，DRX)模式来不定期接收寻呼消息。UE在一个DRX的周期内，只在相应的寻呼帧(paging frame，PF)上的PO时刻醒来进行寻呼消息的接收。在一个DRX周期内，终端可以只在PO出现的时间位置上去接收控制信息，然后再根据控制信道的调度信息去接收数据，而在DRX周期以外的其它时间，UE可以处于睡眠状态，以达到节省功耗的目的。
现有技术在实现过程中，终端只在DRX周期中的PO时刻接收寻呼消息。而在非授权频段中，信号在传输前，包括寻呼消息传输前需要执行先听后说(listen before talk，LBT)。即基站只有在执行LBT成功，在抢占资源成功时才能发送信号，而每次资源抢占的结果有很大的不确定性。因此，现有技术中半静态配置或隐式确定的寻呼时机可能由于执行LBT的失败，导致在先前确定的PO时刻也无法发送寻呼消息，从而造成基站实际可发送的寻呼机严重减少，而寻呼消息携带的一些重要信息未能及时传递给用户。
综上分析可知，现有技术存在由于执行LBT失败导致的寻呼机会减少的问题，降低了寻呼消息的传输效率。
发明内容
本申请实施例提供了一种寻呼方法、终端设备以及网络设备，用于提高寻呼消息的传输效率。
为解决上述技术问题，本申请实施例提供以下技术方案：
第一方面，本申请实施例提供一种寻呼方法，包括：第一终端设备在不连续接收周期内确定所述第一终端设备的第一寻呼时机；当所述第一寻呼时机上的信道侦听失败时，所述第一终端设备在时间窗内接收第一寻呼消息，所述时间窗的起始位置通过所述第一寻呼时机确定，所述时间窗包括至少一个寻呼时机。在本申请实施例中，第一终端设备可以确定一个非连续接收周期中用于发送第一寻呼消息的第一寻呼时机，如果在此第一寻呼时机上网络设备未能实际发送寻呼消息，由于信道侦听失败而未能实际使用的第一寻呼时机转移到一个时间窗中的下一个寻呼时机，而第一终端设备可以根据第一寻呼时机在一个时间窗内的其他寻呼时机上来接收第一寻呼消息，从而提高寻呼消息的传输效率。
在第一方面的一种可能实现中，所述时间窗包括的每个寻呼时机对应至少一个寻呼位置，其中，不同的寻呼位置占用不同的带宽区域。其中，每个寻呼时机在频域上对应至少一个寻呼位置。例如每个寻呼时机对应至少两个寻呼位置，不同的寻呼位置占用不同的带宽区域。其中，一个带宽区域可以是一个带宽部分，一个带宽区域也可以是一个子带，例如该子带为20MHz的带宽，或者40MHz的带宽等。对于第一寻呼时机对应的多个寻呼位置，这些寻呼位置在频域上占用不同的带宽区域。
在第一方面的一种可能实现中，所述第一终端设备在时间窗内接收第一寻呼消息，包括：所述时间窗还包括第二寻呼时机，所述第一终端设备在所述第二寻呼时机接收所述第一寻呼消息。其中，网络设备在第一寻呼时机上的信道侦听失败时，网络设备根据该第一寻呼时机确定出时间窗的起始位置，网络设备可以在该时间窗内第二寻呼时机向第一终端设备发送第一寻呼消息，相应的，第一终端设备可以在该时间窗内确定出第二寻呼时机，此时第一终端设备可以在第二寻呼时机接收第一寻呼消息，从而解决了因为第一寻呼时机的信道侦听失败无法传输寻呼消息的问题。
在第一方面的一种可能实现中，所述第一终端设备在所述第二寻呼时机接收所述第一寻呼消息，包括：所述第二寻呼时机对应至少两个寻呼位置，所述第一终端设备在所述第二寻呼时机对应的第一寻呼位置上接收所述第一寻呼消息，所述第二寻呼时机对应的第二寻呼位置用于第二终端设备接收第二寻呼消息。其中，第一终端设备在第二寻呼时机对应的第一寻呼位置上接收第一寻呼消息，第二终端设备可以在第二寻呼时机对应的第二寻呼位置上接收第二寻呼消息，提高了第一寻呼消息的传输效率。
在第一方面的一种可能实现中，所述第二寻呼位置为最小索引的带宽区域对应的寻呼位置或最大索引的带宽区域对应的寻呼位置。第二终端设备确定出第二寻呼时机对应的第二寻呼位置可以采用预定义的方式。其中，可以直接定义最小索引的带宽区域对应的寻呼位置或最大索引的带宽区域对应的寻呼位置为第二寻呼位置，最小索引指的是带宽区域的索引号最小，最大索引是指带宽区域的索引号最大，此处的带宽区域指的是信号传输所占用的带宽范围，带宽区域可以是频域上的子带。其中，一个带宽区域可以是一个带宽部分，一个带宽区域也可以是一个子带。
在第一方面的一种可能实现中，所述第一终端设备在所述第二寻呼时机对应的第一寻 呼位置上接收所述第一寻呼消息之前，所述方法还包括：所述第一终端设备接收第一参考信号序列，所述第一参考信号序列携带指示信息，所述指示信息用于指示所述第一寻呼消息所在的第一寻呼位置。其中，网络设备可以在第一寻呼位置上发送第一寻呼消息之前，先发送一个参考信号序列，例如网络设备发送第一参考信号序列，则第一终端设备可以接收该第一参考信号序列，第一参考信号序列携带第一寻呼位置上传输的第一寻呼消息的指示信息，此第一寻呼消息的指示信息用于指示第一寻呼时机相对于第二寻呼时机的偏移值。
在第一方面的一种可能实现中，所述指示信息还用于指示所述第一寻呼消息对应于所述时间窗内的所述第一寻呼时机。由于第一寻呼时机的信道侦听失败无法发送第一寻呼消息，该第一寻呼消息使用了第二寻呼时机对应的第一寻呼位置来发送，第一终端设备解析该指示信息可以确定出第二寻呼时机对应的第一寻呼位置上的第一寻呼消息对应于第一寻呼时机。
在第一方面的一种可能实现中，所述第一参考信号序列用于指示信号发送的起始位置信息。其中，第一参考信号序列可以为指示信号传输起始的初始参考信号序列，例如传输的信号可以是控制信道、同步信号、广播信道、下行参考信号或任意其他下行信号等。

在第二方面的一种可能实现中，所述时间窗包括的每个寻呼时机对应至少一个寻呼位置，其中，不同的寻呼位置占用不同的带宽区域。例如每个寻呼时机对应至少两个寻呼位置，不同的寻呼位置占用不同的带宽区域。其中，一个带宽区域可以是一个带宽部分，一个带宽区域也可以是一个子带，例如该子带为20MHz的带宽，或者40MHz的带宽等。对于第一寻呼时机对应的多个寻呼位置，这些寻呼位置在频域上占用不同的带宽区域。

终端设备1-6，又称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)、终端等，是一种向用户提供语音和/或数据连通性的设备，或，设置于该设备内的芯片，例如，具有无线连接功允许的手持式设备、车载设备等。目前，一些终端设备的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)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、远程手术(remote medical surgery)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。本申请实施例提供的终端设备可以是低复杂度终端设备和/或处于覆盖增强A模式下的终端设备。
在本申请实施例中，基站和UE1～UE6组成一个通信系统，在该通信系统中，基站发送 系统信息、RAR消息和寻呼消息中的一种或多种给UE1～UE6中的一个或多个UE，此外，UE4～UE6也组成一个通信系统，在该通信系统中，UE5可以作为基站的功能实现，UE5可以发送系统信息、控制信息和寻呼消息中的一种或多种给UE4和UE6中的一个或多个UE。
网络设备向终端设备发送的寻呼消息在空口通过物理下行共享信道(physical downlink shared channel，PDSCH)承载，在接收寻呼消息之前，终端设备需要先去监听物理下行控制信道(physical downlink control channel，PDCCH)，然后根据PDCCH上是否有携带寻呼无线网络临时标识(paging-radio network tempory identity，P-RNTI)，来判断网络在本次寻呼周期是否有发寻呼消息给自己。空闲态的终端设备可以使用不连续接收(discontinuous reception，DRX)功能减少功率消耗，增加电池寿命，即在一个DRX循环(cycle)周期内，终端可以只在寻呼时机出现的时间位置上去接收控制信息，然后再根据需要去接收数据，终端设备在DRX的循环周期以外的其它时间可以睡眠，以达到省电的目的，该DRX的循环周期也可以称为DRX周期。另外，对于空闲态的终端设备来说，如果总频繁的醒来去接收寻呼消息，也将导致终端设备的功耗增加，从而无法实现省电和增加电池寿命的目的。
终端设备在一个DRX的周期内，只在相应的寻呼帧(paging frame，PF)上的寻呼时机PO进行监听PDCCH上是否携带有P-RNTI，进而去判断相应的PDSCH上是否有承载寻呼消息。如果在PDCCH上携带有P-RNTI，就按照PDCCH上指示的PDSCH的参数去接收PDSCH上的数据；如果终端设备在PDCCH上未解析出P-RNTI，则无需再去接收PDSCH，就可以依照DRX周期进入休眠。利用这种机制，在一个DRX周期内，终端可以只在PO出现的时间位置上去接收PDCCH，然后再根据需要去接收PDSCH。而在其它时间可以睡眠，以达到省电的目的。
为解决现有技术中终端设备在一个DRX周期内由于执行LBT失败导致的寻呼机会减少的问题，本申请实施例提出如下的寻呼方法，请参阅图2所示，为本申请实施例提供一种的网络设备和第一终端设备之间的交互流程示意图，本申请实施例提供的寻呼方法，主要包括如下步骤：
201、网络设备确定第一终端设备的第一寻呼时机。
在本申请实施例中，网络设备需要和第一终端设备进行通信时，网络设备首先确定出第一寻呼时机，该第一寻呼时机是分配给第一终端设备的寻呼时机。
本申请实施例中每个寻呼帧中包括多个寻呼时机，例如一个寻呼帧中可以包括4个寻呼时机，网络设备需要和第一终端设备进行通信时，网络设备首先确定第一终端设备在一个寻呼帧中的哪个寻呼时机上做监听和寻呼消息的接收，例如第一寻呼时机是第一终端设备可以进行监听和接收的一个寻呼时机。通过寻呼帧和寻呼时机的配置，网络设备和终端设备可以按照预定义的规则确定寻呼时机在时域上的候选位置。
在本申请的一些实施例中，步骤201网络设备确定第一终端设备的第一寻呼时机，包括：
网络设备根据第一终端设备的标识确定第一终端设备的第一寻呼时机。
其中，第一寻呼时机可以由网络设备根据该第一终端设备的标识来确定，例如网络设备根据第一终端设备的UE ID确定出第一寻呼时机。第一终端设备的标识可以有多种，例 如可以根据第一终端设备的国际移动用户识别码(international mobile subscriber identification number，IMSI)确定出第一寻呼时机。
202、第一终端设备在不连续接收周期内确定第一终端设备的第一寻呼时机。
本申请实施例中一个不连续接收周期内包括至少一个寻呼帧，每个寻呼帧中包括至少一个寻呼时机，第一终端设备根据预定义规则确定在一个寻呼帧的寻呼时机上去尝试检测和接收寻呼消息，例如第一寻呼时机是第一终端设备根据网络设备给终端设备的寻呼帧和寻呼时机配置确定出的，第一终端设备可以按照预定义的规则确定寻呼时机在时域上的候选位置。
在本申请的一些实施例中，步骤202第一终端设备在不连续接收周期内确定第一终端设备的第一寻呼时机，包括：
第一终端设备根据第一终端设备的标识，在不连续接收周期内确定第一终端设备的第一寻呼时机。
其中，第一寻呼时机可以由第一终端设备根据该第一终端设备的标识来确定，例如第一终端设备根据UE ID确定出第一寻呼时机。第一终端设备的标识可以有多种，例如可以根据第一终端设备的IMSI确定出第一寻呼时机。
203、当网络设备在第一寻呼时机上的信道侦听失败时，网络设备在时间窗内发送第一寻呼消息，时间窗的起始位置通过第一寻呼时机确定，时间窗包括至少一个寻呼时机。
在本申请的一些实施例中，时间窗包括的寻呼时机个数是预定义的，或者是网络设备发送给第一终端设备的。其中，网络设备可以预定义该时间窗包括的寻呼时机个数，例如一个时间窗内可以包括8个寻呼时机，则第一终端设备可以按照预定义的方式确定出时间窗内的包括的寻呼时机个数。或者，网络设备在确定出时间窗包括的寻呼时机个数之后，网络设备还可以向第一终端设备发送通知消息，以使得第一终端设备根据该通信消息确定出时间窗包括的寻呼时机个数。
在本申请实施例中，网络设备确定出第一终端设备的第一寻呼时机之后，网络设备在该第一寻呼时机上或该第一寻呼时机之前进行传输前的信道侦听，即网络设备可以在第一寻呼时机上或该第一寻呼时机之前进行LBT。若信道侦听成功则说明网络设备抢占到信号传输的资源，网络设备可以使用该资源向第一终端设备发送第一寻呼消息。若信道侦听失败则说明该网络设备没有抢占到信号传输的资源，此时网络设备不能在第一寻呼时机发送第一寻呼消息。针对网络设备在第一寻呼时机上的信道侦听失败的情况，本申请实施例中网络设备在根据第一寻呼时机确定的时间窗内继续尝试发送第一寻呼消息，从而增加了寻呼消息的发送次数，保证了寻呼消息的传输效率。
在本申请实施例中，时间窗是指包括至少一个寻呼时机的一个时间段或者时间单元，该时间窗的起始位置通过第一寻呼时机确定。时间窗的起始位置可以由信道侦听失败时的第一寻呼时机的时域位置确定。更进一步地，时间窗的起始位置也可以是信道侦听失败时的第一寻呼时机之后的第一个可用寻呼时机的时域位置。即，时间窗的起始位置可以为第一寻呼时机所在的时域位置或根据第一寻呼时机确定的另一个时域位置，这里不做具体限定。另外，时间窗可以包括第一寻呼时机和第二寻呼时机，或者时间窗可以不包括第一寻呼时机，该时间窗包括第二寻呼时机。本申请实施例中时间窗的时长大小可以为预定义的， 或者是网络设备配置给第一终端设备的。本申请实施例中时间窗的时长大小是小于或等于一个不连续接收周期的，并且该时间窗在一个不连续接收周期内，第一终端设备只需要在不连续接收周期内的一个时间窗内唤醒，该时间窗可以是一个时间范围，例如时间窗可以是时间单元，可以是一个时间偏移长度，也可以是寻呼时机的个数等形式，此处不做限定。
在本申请实施例中，时间窗是指包括至少两个寻呼时机的一个时间段或者时间单元，该时间窗的起始位置通过第一寻呼时机确定。时间窗的起始位置可以由信道侦听失败时的第一寻呼时机的时域位置确定。更进一步地，时间窗的起始位置也可以是信道侦听失败时的第一寻呼时机之后的第一个可用寻呼时机的时域位置。即，时间窗的起始位置可以为第一寻呼时机所在的时域位置或根据第一寻呼时机确定的另一个时域位置，这里不做具体限定。另外，时间窗可以包括第一寻呼时机和第二寻呼时机，或者时间窗可以不包括第一寻呼时机，该时间窗包括第二寻呼时机和第三寻呼时机。该时间窗可以是一个时间范围，例如时间窗可以是时间单元，可以是一个时间偏移长度，也可以是寻呼时机的个数等形式，此处不做限定。
在本申请实施例中，预定义一个时间窗或网络设备为第一终端设备配置一个时间窗，时间窗包括至少一个寻呼时机，当第一寻呼时机上的信道侦听失败时，可以根据第一寻呼时机在时间窗内偏移到下一个可用的寻呼时机，从而该下一个可用的寻呼时机用于传输第一寻呼消息，其中，第一寻呼消息为由于信道侦听失败而未能实际发送给第一终端设备的寻呼消息。举例说明如下，如果在时域上确定的第一寻呼时机由于LBT失败，使得第一寻呼消息未能实际发送时，基站可在一个时间窗内的其他可用的寻呼时机上发送该第一寻呼消息。
在本申请的一些实施例中，步骤203网络设备在时间窗内发送第一寻呼消息，包括：
时间窗还包括第二寻呼时机，网络设备在第二寻呼时机向第一终端设备发送第一寻呼消息；以及，
网络设备在第二寻呼时机向第二终端设备发送第二寻呼消息。
其中，在时间窗内包括第一寻呼时机和第二寻呼时机，网络设备在第一寻呼时机上的信道侦听失败时，网络设备可以将该时间窗内第二寻呼时机同时用于向第一终端设备和第二终端设备发送寻呼消息，例如网络设备在第二寻呼时机向第一终端设备发送第一寻呼消息，网络设备在第二寻呼时机向第二终端设备发送第二寻呼消息。相应的，第一终端设备可以在该时间窗内确定出第二寻呼时机，此时第一终端设备可以在第二寻呼时机接收第一寻呼消息，从而解决了因为第一寻呼时机的信道侦听失败无法传输寻呼消息的问题。
在本申请的一些实施例中，网络设备在第二寻呼时机向第一终端设备发送第一寻呼消息；以及，网络设备在第二寻呼时机向第二终端设备发送第二寻呼消息，包括：
第二寻呼时机对应至少两个寻呼位置，网络设备在第二寻呼时机对应的第一寻呼位置上向第一终端设备发送第一寻呼消息，以及，
网络设备在第二寻呼时机对应的第二寻呼位置上向第二终端设备发送第二寻呼消息。
其中，对于第二寻呼时机，在频域上分别对应第一寻呼位置和第二寻呼位置，此时网络设备可以将第二寻呼时机对应的两个寻呼位置中的其中一个寻呼位置(例如第一寻呼位置)用于向第一终端设备发送第一寻呼消息，而将第二寻呼时机对应的两个寻呼位置中的 另一个寻呼位置(例如第二寻呼位置)用于向第二终端设备发送第二寻呼消息。此时第一终端设备在第二寻呼时机对应的第一寻呼位置上接收第一寻呼消息，第二终端设备可以在第二寻呼时机对应的第二寻呼位置上接收第二寻呼消息。
在本申请的一些实施例中，网络设备在时间窗内发送第一寻呼消息之前，本申请实施例提供的寻呼方法还包括：
网络设备向第一终端设备发送第一参考信号序列，第一参考信号序列携带指示信息，指示信息用于指示第一寻呼消息所在的第一寻呼位置。
其中，网络设备可以在第一寻呼位置上发送第一寻呼消息之前，先发送一个参考信号序列，例如网络设备发送第一参考信号序列，则第一终端设备可以接收该第一参考信号序列，第一参考信号序列携带第一寻呼位置上传输的第一寻呼消息的指示信息，此第一寻呼消息的指示信息可以为一个相对第二寻呼时机的索引，第一终端设备解析该第一参考信号序列得到指示信息，第一终端设备从该指示信息可以确定出第一寻呼时机对应的第一寻呼消息所在的第一寻呼位置。第一终端设备通过接收第一参考信号序列可以确定出第一寻呼消息所在的第一寻呼位置，从而第一终端设备可以检测和接收到该第一寻呼位置上发送给该第一终端设备的第一寻呼消息。
204、当第一寻呼时机上的信道侦听失败时，第一终端设备在时间窗内接收第一寻呼消息，时间窗的起始位置通过第一寻呼时机确定，时间窗包括至少一个寻呼时机。
在本申请实施例中，第一终端设备在确定出该第一终端设备的第一寻呼时机之后，若网络设备在第一寻呼时机上信道侦听失败时，网络设备无法在第一寻呼时机发送第一寻呼消息，此时网络设备可以根据该第一寻呼时机确定出时间窗，网络设备使用该时间窗内的下一个可用的寻呼时机来发送第一寻呼消息，因此第一终端设备也可以根据该第一寻呼时机确定出时间窗，在时间窗内尝试检测和接收第一寻呼消息。对于时间窗的说明，详见步骤203中的举例说明。
在本申请的一些实施例中，时间窗包括的每个寻呼时机对应至少一个寻呼位置，其中，不同的寻呼位置占用不同的带宽区域。
其中，每个寻呼时机在频域上对应至少一个寻呼位置。例如每个寻呼时机对应至少两个寻呼位置，不同的寻呼位置占用不同的带宽区域。其中，一个带宽区域可以是一个带宽部分(bandwith part，BWP)，一个带宽区域也可以是一个子带，例如该子带为20MHz的带宽，或者40MHz的带宽等。对于第一寻呼时机对应的多个寻呼位置，这些寻呼位置在频域上占用不同的带宽区域。
在本申请的一些实施例中，前述步骤204第一终端设备在时间窗内接收第一寻呼消息，包括：
时间窗内还包括第二寻呼时机，第一终端设备在时间窗内的第二寻呼时机接收第一寻呼消息。
其中，在时间窗内包括第二寻呼时机，网络设备在第一寻呼时机上的信道侦听失败时，网络设备根据该第一寻呼时机确定出时间窗的起始位置，网络设备可以在该时间窗内第二寻呼时机向第一终端设备发送第一寻呼消息，相应的，第一终端设备可以在该时间窗内确定出第二寻呼时机，此时第一终端设备可以在第二寻呼时机接收第一寻呼消息，从而解决 了因为第一寻呼时机的信道侦听失败无法传输寻呼消息的问题。
在本申请的一些实施例中，第二寻呼时机可以是第二终端设备的寻呼时机。另外，时间窗内还可以存在用于第一终端设备和第二终端设备使用的第三寻呼时机，该第三寻呼时机可以是第三终端设备的寻呼时机。在本申请实施例中，第一终端设备还可以使用该第三寻呼时机接收第一寻呼消息，从而提高寻呼消息的传输效率。
进一步的，在本申请的一些实施例中，时间窗内的每个寻呼时机对应多个寻呼位置。第一终端设备在时间窗内的第二寻呼时机接收寻呼消息，包括：
第二寻呼时机对应至少两个寻呼位置，第一终端设备在第二寻呼时机对应的第一寻呼位置上接收第一寻呼消息，第二寻呼时机对应的第二寻呼位置用于第二终端设备接收第二寻呼消息。
其中，对于第二寻呼时机，在频域上分别对应第一寻呼位置和第二寻呼位置，此时网络设备可以将第二寻呼时机对应的两个寻呼位置中的其中一个寻呼位置(例如第一寻呼位置)用于向第一终端设备发送第一寻呼消息，而将第二寻呼时机对应的两个寻呼位置中的另一个寻呼位置(例如第二寻呼位置)用于向第二终端设备发送第二寻呼消息。此时第一终端设备在第二寻呼时机对应的第一寻呼位置上接收第一寻呼消息，第二终端设备可以在第二寻呼时机对应的第二寻呼位置上接收第二寻呼消息。
在本申请的一些实施例中，第二寻呼时机对应的第一寻呼位置可以通过隐式确定，例如该第一寻呼位置可以由第一终端设备根据该第一终端设备的设备标识来确定，例如第一终端设备根据UE ID确定出第二寻呼时机对应的第一寻呼位置，从而使得第一终端设备可以获取到第二寻呼时机对应的第一寻呼位置。
在本申请的一些实施例中，第二寻呼位置为预定义的寻呼位置。网络设备可以按照预定义的方式来确定出第二寻呼时机对应的第二寻呼位置，从而网络设备可以在第二寻呼时机对应的第二寻呼位置上向第二终端设备发送第二寻呼消息，相应的第二终端设备可以在第二寻呼时机对应的第二寻呼位置上接收第二寻呼消息，第二终端设备通过预定义的第二寻呼位置，可以接收到网络设备发送的第二寻呼消息。
进一步的，在本申请的一些实施例中，第二寻呼位置为最小索引的带宽区域对应的寻呼位置或最大索引的带宽区域对应的寻呼位置。其中，第二终端设备确定出第二寻呼时机对应的第二寻呼位置可以采用预定义的方式。其中，预定义的方式有多种，例如可以直接定义最小索引的带宽区域对应的寻呼位置或最大索引的带宽区域对应的寻呼位置为第二寻呼位置，最小索引指的是带宽区域的索引号最小，最大索引是指带宽区域的索引号最大，此处的带宽区域指的是信号传输所占用的带宽范围，带宽区域可以是频域上的子带。其中，一个带宽区域可以是一个带宽部分，一个带宽区域也可以是一个子带，例如该子带为20MHz的带宽，或者40MHz的带宽等。举例说明如下，网络设备在第二寻呼时机上进行信道侦听成功时，该第二寻呼时机对应的待传输寻呼消息默认被映射到至少两个子带中某个预定义的子带上，例如，最小索引对应的子带可以是预定义的第二寻呼位置，或最大索引对应的子带可以是预定义的第二寻呼位置等，其中，子带可以为以20兆赫兹的整数倍为最小粒度的信道带宽。
在本申请的一些实施例中，第一终端设备在第二寻呼时机对应的第一寻呼位置上接收 第一寻呼消息之前，本申请实施例提供的寻呼方法还包括：
第一终端设备接收第一参考信号序列，第一参考信号序列携带指示信息，指示信息用于指示第一寻呼消息所在的第一寻呼位置。
其中，网络设备可以在第一寻呼位置上发送第一寻呼消息之前，先发送一个参考信号序列，例如网络设备发送第一参考信号序列，则第一终端设备可以接收该第一参考信号序列，第一参考信号序列携带第一寻呼位置上传输的第一寻呼消息的指示信息，此第一寻呼消息的指示信息用于指示第一寻呼时机相对于第二寻呼时机的偏移值。例如，以第二寻呼时机为当前寻呼时机，则该第一寻呼消息的指示信息用于指示第一寻呼时机相对于当前寻呼时机的偏移值。第一终端设备解析该第一参考信号序列得到指示信息，第一终端设备从该指示信息可以确定出第一寻呼消息所在的第一寻呼位置。第一终端设备通过接收第一参考信号序列可以确定出第一寻呼消息所在的第一寻呼位置，从而第一终端设备可以检测和接收到该第一寻呼位置上的第一寻呼消息。
在本申请的一些实施例中，第一参考信号序列可以为用于标识数据传输的起始的初始信号序列，或控制信道的解调参考信号序列，或信道状态信息参考信号序列，或时频同步跟踪参考信号序列，或同步类信号序列等，此处不做限定。
在本申请的一些实施例中，第一参考信号序列中的指示信息，还用于指示寻呼消息对应于时间窗内的第一寻呼时机。即网络设备使用该指示信息指示即将在第一寻呼位置上发送的第一寻呼消息对应于时间窗内的第一寻呼时机，由于第一寻呼时机的信道侦听失败无法发送第一寻呼消息，该第一寻呼消息使用了第二寻呼时机对应的第一寻呼位置来发送，第一终端设备解析该指示信息可以确定出第二寻呼时机对应的第一寻呼位置上的第一寻呼消息对应于第一寻呼时机。
在本申请的一些实施例中，第一参考信号序列，还用于指示信号发送的起始位置信息。其中，第一参考信号序列可以为指示信号传输起始的初始参考信号序列，例如传输的信号可以是控制信道、同步信号、广播信道、下行参考信号或任意其他下行信号等，这里不做具体限定。
通过前述实施例的举例说明可知，在本申请实施例中，网络设备可以确定一个非连续接收周期中用于发送第一寻呼消息的第一寻呼时机，如果在此第一寻呼时机上网络设备未能实际发送寻呼消息，网络设备可以将由于信道侦听失败而未能实际使用的第一寻呼时机转移到一个时间窗中的下一个寻呼时机，而第一终端设备可以根据第一寻呼时机在一个时间窗内的其他寻呼时机上来接收第一寻呼消息，从而提高寻呼消息的传输效率。
为便于更好的理解和实施本申请实施例的上述方案，下面举例相应的应用场景来进行具体说明。
本申请实施例可以实现寻呼消息传输流程的增强，以补偿由于执行LBT失败带来的寻呼时机减少的问题。本申请实施例涉及的网元为UE和基站，如图3所示，为本申请实施例提供的一种基站通过多波束发送寻呼消息的示意图。在NR授权频段中，当网络设备需要寻呼UE时，由于网络没有UE的上下文信息，不知道需要通过什么波束为UE发送寻呼消息，因此需要通过多个波束进行扫描，即通过多个波束发送寻呼消息以达到较好的覆盖。
5G系统中的同步信号(synchronization signal，SS)也支持多波束发送，便于小区 内的UE接收。同步信号的多波束发送是通过定义SS突发信号集(burst set)实现的。一个SS突发信号集包含一个或多个SS突发，一个SS突发包含一个或多个SS块(block)。一个SS块用于承载一个波束的同步信号，因此，一个SS突发信号集包含小区内SS block个数的同步信号。
在现有技术中，UE在一个DRX循环周期中只有一个PO，其中一个PO可以包括一轮波束下的寻呼消息(即多个寻呼时机)，但在非授权频谱中，由于受到不确定的LBT结果的影响。因此当基站LBT结果失败没有抢占到资源时，一些半静态或根据预定义规则决定的寻呼时机将不能正常发送，从而导致基站真正可发送的寻呼机会大大被削减。
本申请实施例中，为了实现NR非授权频谱下寻呼消息的发送，可以采用以下方式：
UE通过系统消息获得DRX周期和DRX周期内的用于确定小区的PF和PO的配置信息，通过该配置信息可以确定DRX周期内PF的集合和每个PF内PO的个数和位置。UE根据DRX周期内PF的集合和每个PF内PO的个数和位置，以及nB，确定PO突发信号集(burst set)包含的PF的个数。其中，nB表示一个DRX周期中PO的总数。nB是网络在系统消息广播(system information broadcast，SIB)2中广播的，其取值范围是4T，2T，T，T/2，T/4，T/8，T/16，T/32，单位是无线帧。
UE根据UE ID计算得到在DRX周期内UE需要接受寻呼消息的PF和PO burst set的位置，即不同的UE根据其UE ID分别计算各自的PO burst set。例如，Nps表示DRX周期内PO burst set的个数，DRX周期内的PO burst set的编号为1,…,Nps。则UE接收的PO burst set编号＝UE ID mod Nps。
如图4所示，为本申请实施例提供的一种PF和PO之间的关系示意图，一个PO burst set包含两个PF中的PO，即PF0和PF1。每个PF中包含4个PO。Nb＝8，若DRX周期＝32，则Nps＝16，UE根据自己的UE ID计算得到其接收寻呼消息的PO burst set的位置。
接下来说明UE可以通过如下公式计算出寻呼位置PF：
PF＝SFN mod T＝(T/N)×(UE ID mod N)。
其中，SFN是系统帧号，满足上面公式的所有SFN的值对应的无线帧都是PF,PF可以通过上述公式SFN mod T计算得到，对于前述实施例中的第一终端设备和第二终端设备在获取到各自的UE ID之后，都可以通过上述公式计算出各自的寻呼位置。由于SFN的取值范围是0～1023，所以PF会在0～1023的取值范围内周期性的出现，mod表示取模计算，/表示相除，×表示相乘。
T是UE的DRX周期长度，表示一个寻呼周期的长度，单位为无线帧(10ms)。T＝min(Tc，Tue)，即取Tc和Tue中间的最小值。其中Tc，Tue分别表示核心网和无线侧设置的寻呼周期，一般情况无线侧的寻呼周期小于核心网周期，默认等于无线侧寻呼周期，该参数从SIB2中读取。而Tc从SIB1的寻呼消息中获取。
N表示一个DRX周期中的PF的个数，N＝min(T,nB)，nB从SIB2中读取，nB表示一个DRX周期中PO的总数。nB是网络在SIB2中广播的，nB的取值可以是如下取值中的任意一种：4T，2T，T，T/2，T/4，T/8，T/16，T/32，单位是无线帧，不限定的是，nB也可以取除上述值以外的其它值。
UE ID可以包含在SIB1的寻呼消息中，通过IMSI模1024计算得到，即UE ID＝IMSI mod 1024。
接下来说明寻呼时机的确认。寻呼时机是寻呼帧包含的寻呼时机所在位置对应的子帧号，该时刻可以通过Ns与i_s对应关系获取，Ns表示一个PF中的PO的个数，i_s表示在PF中的第几个PO。以频分双工(frequency division duplexing，FDD)为例，对应关系如下表1所示。
  i_s＝0 i_s＝1 i_s＝2 i_s＝3
Ns＝1 Subframe 9 N/A N/A N/A
Ns＝2 Subframe 4 Subframe 9 N/A N/A
Ns＝4 Subframe 0 Subframe 4 Subframe 5 Subframe 9
其中，Ns＝max(1,nB/T)，表示一个PF中的PO的个数。
i_s＝floor(UE ID/N)mod Ns。
下面举例说明寻呼帧与寻呼时刻的计算。
这里寻呼周期的默认值为128，则T＝128。nB设置为T，即128，那么N＝128；Ns＝1.
第一步，计算寻呼帧位置。假设用户的IMSI＝448835805669362，则根据公式求得。
寻呼帧位置PF＝(T div N)*(UE ID mod N)＝(128/128)*((448835805669362mod 1024)mod 128)＝114。
则寻呼帧的位置可能出现在SFN＝(128*i)+114，(其中i＝0到N，但是SFN<＝1024)。如，寻呼帧的位置可能为114、242、370、498、626、754、882……。
第二步，寻呼时机确认。求Ns和i_s，根据公式求得。
Ns＝max(1,nB/T)＝1；
i_s＝floor(UE ID/N)mod Ns＝floor((448835805669362mod 1024)/128)＝0按照表1对应关系，Ns＝1&i_s＝0＝>PO＝9,即PO在寻呼帧的9子帧位置。
现有技术中受到LBT结果的影响，上述公式确定出的寻呼时机PO的位置有可能无效，而为补偿上述被LBT失败从而无效掉的PO的发送机会，可预定义一个时间窗或基站为UE配置一个时间窗。当根据上式确定的时刻i的PO被无效时，此PO可被偏移到时间窗内的下一个可获得的寻呼时机，例如偏移到PO(j)。对于时刻j，基站在至少一个子带上LBT成功了，且时刻j为不同于时刻i的一个寻呼发射时刻。一个时间窗可以包括至少一个寻呼时机PO，此处的至少一个寻呼时机默认指的是时域上的至少一个寻呼时机。一个寻呼帧内包括的寻呼时机PO的个数由系统信息配置给UE，而每种PO个数下各个PO的时域位置在基站和UE侧是预定义好的。
此外，考虑到非授权频谱资源上的数据传输通常可占用更大的传输带宽。例如20MHz，40MHz,80MHz，160MHz等。在大带宽场景下，基站在数据传输前需要在多个20MHz的子带上进行LBT，同样只有LBT成功的子带上才能进行数据传输。某个时刻，基站可能在多个子带上均LBT成功，从而可获得在多个候选子带上传输寻呼信息的机会。子带以非授权频谱时信号传输的最小信道带宽20MHz为例仅是一种示意。上述子带的定义可以为非20MHz的其他带宽值，例如40MHz，60MHz等，这里也不做具体限定。
在根据上式确定的PO对应的发送时刻j，如果基站在至少两个子带上LBT成功，则时 刻j对应的PO默认映射在至少两个子带中的某个确定的子带上。可选地，该确定的子带可以是该至少两个子带中对应了最小子带索引的一个子带。或，该确定的子带也可以是该至少两个子带中对应了最大子带索引的一个子带，这里不做具体限定。而所述至少两个子带中的其他子带可以分配给之前LBT失败的其他PO，例如，上述中时刻i的PO。
进一步，上述剩余子带被用来传输哪个PO可以根据预定义的规则来确定，例如根据UE ID来隐式决定，或根据UE ID和子带ID来联合隐式决定等，这里不做具体限定。
剩余子带被用来传输哪个PO也可以由基站显式指示给UE。例如，基站通过参考信号序列来携带每个子带上传输的PO的信息。可选地，此参考信号序列可以为用于数据传输识别的初始信号序列或控制信道的解调参考信号序列或信道状态信息参考信号序列或同步类信号序列等，这里不做具体限定。
为尽可能减少参考信号序列携带的信息比特数，提高参考信号序列的检测性能，此指示信息可以为以当前子带对应的寻呼时机PO为参考点，对一个时间窗内包含的所有时域PO的相对于当前参考点的相对索引指示。例如，假定一个时间窗内包含的时域PO个数为3，而当前子带对应的寻呼时机PO为时间窗内的第3个PO，则其他被转移过来的其他PO相对于此参考PO的相对索引指示值要么为1，要么为2。因此，参考信号序列所需要携带1比特即可。
如图5所示，为本申请实施例提供的一种时间窗内通过两个PO发送寻呼消息的示意图。以每个时刻的寻呼时机在频域上有3个子带(sub band)的传输机会为例，首先根据时域PF、PO的确定规则，所有的UE在时域上被分成4组，其中UE0代表第一组UE，UE1代表第二组UE，UE2代表第三组UE，而UE3代表第四组UE。对于第一组UE根据上述公式确定的时域PO位置为PO 0，但PO 0由于受到LBT结果失败的影响未能实际传输，因此，PO 0被转移到以PO 0为起点，3个PO为长度的一个时间窗的第三个PO中的子带1中，第三个PO时刻为用于第三组UE的一个PO时刻，在第三个PO时刻上基站在子带1和子带2上均LBT成功了，此时，子带2上的PO机会默认给第三组UE，从而剩余的子带1上的PO机会就可以转移给第一组UE。
通过前述的举例说明可知，网络设备可以确定一个非连续接收周期中用于发送第一寻呼消息的第一寻呼时机，如果在此第一寻呼时机上网络设备未能实际发送寻呼消息，网络设备可以将由于信道侦听失败而未能实际使用的第一寻呼时机转移到一个时间窗中的下一个寻呼时机，而UE可以根据第一寻呼时机在一个时间窗内的其他寻呼时机上来接收第一寻呼消息，从而提高寻呼消息的传输效率。另外，本申请实施例中UE只需要在一个DRX周期内的一些预定义的时刻被唤醒，而在DRX周期内的其他时刻进入休眠，本申请实施例中UE使用时间窗内更多的寻呼机会去尝试接收寻呼消息，增加了寻呼消息的接收效率，因此UE仅需在该时间窗内醒来接收寻呼消息而在时间窗外不需要频繁唤醒，可以节省UE功耗，达到省电的目的。本申请实施例中UE使用时间窗内的寻呼机会去尝试接收寻呼消息，增加了寻呼消息的接收效率，并且还可以减少UE的检测复杂度。
现有技术中，UE只会在一个DRX周期中确定多个PO中的一个PO用于接收寻呼消息，而本申请实施例中首先根据预定义的规则，确定一个DRX周期中用于接收寻呼的时刻点PO，如果在此时刻点上基站LBT失败未能实际发送寻呼消息，允许基站将LBT失败的PO转移 到一个时间窗中的下一个PO时刻点进行传输，而UE对应的以预定义的寻呼时刻点PO为起点，在一个时间窗内的其他可获得的PO时机资源上去继续搜索和检测寻呼消息。在此时间窗内可获得的PO时机资源包括LBT成功的时域资源和/或LBT成功的频域资源，基站通过一种参考信号序列来指示LBT失败后被转移的寻呼消息所在的寻呼位置。
前述实施例介绍了本申请实施例提供的一种寻呼方法，另一方面，对于UE的随机接入过程来说，在现有技术中，网络设备根据配置给UE的随机接入信道的时频资源确定随机接入响应所对应的下行控制信道的无线网络临时标识(radio network temporary identifier，RNTI)，对于不同的随机接入信道的时频资源，所对应的下行控制信道的RNTI也将不同，UE需要对多个不同RNTI加扰的下行控制信道进行多次检测尝试，因此现有技术增加了UE的检测复杂度。本申请实施例中，同一个UE基于不同的随机接入资源发送相同的随机接入前导码后，网络设备对UE发送的随机接入前导码进行随机接入响应，通过将多次分别发射的随机接入资源对应的随机接入响应的控制信道关联相同的RNTI，从而UE仅需对相同RNTI加扰的多个下行控制信道进行一次检测尝试即可，极大降低了UE的检测复杂度。接下来请参阅图6所示，为本申请实施例提供的网络设备和终端设备之间的一种交互流程示意图。本申请实施例提供的随机接入方法，主要包括如下步骤：
601、终端设备向网络设备发送K次第一前导码，第一前导码为终端设备需要发送给网络设备的任一个前导码，K次第一前导码对应于K个下行控制信息，K个下行控制信息都采用第一扰码值进行加扰，K为大于1的正整数。
在本申请实施例中，终端设备可以向网络设备多次发送相同的前导码，例如发送次数用K表示，发送的同一个前导码表示为第一前导码，第一前导码为终端设备需要发送给网络设备的任一个前导码。针对终端设备的K次第一前导码，网络设备需要针对K次第一前导码对应发送K个下行控制信息，这K个下行控制信息采用相同的扰码值进行加扰，使用的同一个扰码值表示为第一扰码值。
602、网络设备接收终端设备发送的K次第一前导码，第一前导码为终端设备需要发送给网络设备的任一个前导码，K为大于1的正整数。
在本申请实施例中，针对终端设备发送的K次第一前导码，网络设备在接收到第一前导码后，对应发送K个下行控制信息。
603、网络设备使用第一扰码值对K个下行控制信息进行加扰。
在本申请实施例中，针对终端设备发送的K次第一前导码，网络设备在接收到K次发送的第一前导码之后，网络设备需要发送K个下行控制信息，这K个下行控制信息都采用相同的扰码值进行加扰，使用的同一个扰码值表示为第一扰码值，由于终端设备仅需对相同RNTI加扰的多个下行控制信道进行一次检测尝试，从而可以大大减少终端设备的检测复杂度。
604、网络设备向终端设备发送K个下行控制信息。
在本申请的一些实施例中，K次第一前导码对应K个随机接入资源，第一扰码值为根据K个随机接入资源中的第一随机接入资源确定的。
其中，网络设备针对K次第一前导码发送K个下行控制信息，这K个下行控制信息由同一个扰码值来加扰，使用的同一个扰码值表示为第一扰码值。例如第一扰码值为根据K 个随机接入资源中的第一随机接入资源确定的，即终端设备只需要根据第一随机接入资源就可以确定出用于加扰K个下行控制信息的第一扰码值，不需要针对K次第一前导码对应的K个随机接入资源分别计算K个下行控制信息的扰码值，且终端设备只需要对相同RNTI加扰的多个下行控制信道进行一次检测尝试，可大大减少终端设备的检测复杂度。
进一步的，在本申请的一些实施例中，第一随机接入资源为预定义的随机接入资源；或者，第一随机接入资源为网络设备配置给终端设备的。
其中，网络设备和终端设备侧可以预定义第一随机接入资源，例如预先确定第一随机接入资源为K个随机接入资源中某个确定的随机接入资源。例如，K个随机接入资源中的第一个随机接入资源或K个随机接入资源中的最后一个随机接入资源等，这里不做具体限定，则终端设备可以按照该预定义的方式或规则确定出第一随机接入资源。或者，网络设备在确定出第一随机接入资源之后，网络设备还可以向终端设备发送第一随机接入资源的指示信息，以使得终端设备根据该指示信息确定出K个随机接入资源中的第一随机接入资源。
进一步的，在本申请的一些实施例中，K次第一前导码对应K个随机接入资源，K个随机接入资源属于第一随机接入资源组，第一随机接入资源组为预定义的，或者第一随机接入资源组是网络设备配置给终端设备的。
其中，网络设备可以预定义第一随机接入资源组。例如，根据预定义的规则确定第一随机接入资源组包含的随机接入资源信息，此预定义的规则可选地为：时域上和/或频域上连续的K个随机接入资源组成第一随机接入资源组等，这里不做具体限定。则终端设备可以按照预定义的方式确定出第一随机接入资源组。或者，网络设备在确定出第一随机接入资源组之后，网络设备还可以向终端设备发送第一随机接入资源组的指示信息，以使得终端设备根据该指示信息确定出第一随机接入资源组。可选地，网络设备可直接指示组成第一随机接入资源组的随机接入资源信息，如，随机接入资源的索引号等。可选地，网络设备也可指示组成第一随机接入资源组的任意两个连续的随机接入资源的间隔和/或组成第一随机接入资源组的随机接入资源的个数等信息给终端设备，这里不做具体限定。
605、终端设备在下行控制信息的检测时间窗中，根据第一扰码值接收网络设备发送的K个下行控制信息中的至少一个下行控制信息。
在本申请实施例中，网络设备发送了K个下行控制信息，其中，该下行控制信息可以包括随机接入响应消息的调度信息。由于网络设备采用相同的第一扰码值进行加扰，因此终端设备在此检测时间窗内只需要使用相同的第一扰码值来接收K个下行控制信息中的至少一个下行控制信息，对于终端设备而言，不需要对多个不同RNTI加扰的下行控制信道进行多次检测尝试，因此可以大大减少终端设备的检测复杂度。
为便于更好的理解和实施本申请实施例的上述方案，下面举例相应的应用场景来进行具体说明。
竞争随机接入是指演进基站没有为UE分配专用资源，完全由UE随机发起的随机接入过程。竞争随机接入过程分四步完成，终端向基站发送前导码(即为Msg1)，基站根据接收的前导码向终端发送随机接入响应(Random Access Response，RAR)(即为Msg2)，然后终端与基站进行第一次上行调度传输(即为Msg3)，最后基站向终端反馈竞争解决(即 为Msg4)。具体地，针对基站向终端发送RAR的过程为：基站根据发送前导码的PRACH时频资源位置确定RA-RNTI，然后采用随机接入无线网络临时标识(Random Access Radio Network Temporary Identifier，RA-RNTI)对RAR进行加扰，再将加扰后的RAR及其调度RAR的控制信息发送给终端。相应地，终端根据其发送前导码的随机接入信道(random access channel，RACH)的时频资源信息确定RA-RNTI，然后根据此RA-RNTI解调并接收获得RAR。由此可知，终端需要获得与基站处相同的RA-RNTI，才能获得正确的RAR。目前，终端和基站主要根据用于RACH时频资源的表征时间索引和/或频域位置索引，如时隙号索引、OFDM符号索引、子帧号索引、系统帧号索引和频域位置索引中的至少一个来确定RA-RNTI。为表述方便，下面将随机接入资源统一记为RACH资源。
在非授权频段上，为降低LBT失败带来的RACH发送机会的减少，在基站发送随机接入响应前，终端设备可针对同一个随机接入前导码进行多次RACH传输尝试，由于多次RACH传输对应了相同的随机接入前导码，因此，基站对每次传输的RACH资源响应一个相同RNTI值加扰的下行控制信息，对应地，UE在一个检测时间窗内试图检测多份相同RNTI值加扰的下行控制信息中的至少一份下行控制信息即可。这里，RNTI加扰可以是对下行控制信息的CRC的加扰，也可以是对DCI信息的直接加扰，这里不做具体限定。
在本申请的一些实施例中，随机接入响应的多个下行控制信息对应了相同RNTI值，而对应的多份RACH资源可构成一个RACH资源组，同一组内的RACH资源的随机接入响应对应了相同的RNTI值。此相同的RNTI值可以基于RACH资源组内的某一份参考RACH资源得到的，如，此参考RACH资源可以为RACH资源组内的第一份RACH资源或最后一份RACH资源等，这里不做具体限定。
在本申请的一些实施例中，一个RACH资源组内的参考RACH资源可以是预定义好的，也可以是基站配置给UE的。例如通过剩余最小系统信息(remaining minimum system information，RMSI)通知给UE的。其中，参考信号资源的配置方式也可以是除RMSI外的其他信息或信令。例如，其他系统信息(Other System Information,OSI)或无线资源控制信令(radio resource control,RRC)等，这里不做具体限定。这里的RACH资源组可以与同步信号或者广播信道块(Synchronization Signal/Broadcast Channel Block,SS/BCH Block)到一组随机接入时机(RACH Occasion，RO)映射中的RACH资源组相同或不同，如，这里的RACH资源组可以由SS/BCH Block映射到的RACH资源组中的全部或部分RACH资源组成。
在本申请的一些实施例中，基站和UE可根据下式确定一份RACH资源对应的下行控制信息关联的RNTI值：
RA-RNTI＝1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id。
其中，s_id是该RACH资源对应的第一个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号的索引号(0≤s_id<14)，t_id是该RACH资源在一个系统帧内对应的第一个时隙的索引号(0≤t_id<80),f_id是该RACH资源在频域的索引号(0≤f_id<8),ul_carrier_id是用于该RACH资源传输的上行载波的索引，其中0代表了NR正常上行载波，而1代表了NR辅助上行载波。
在本申请的前述实施例中，随机接入响应前多次发射的RACH资源关联了相同的RNTI 值，该多份RACH资源对应了相同的随机接入前导码，因此对于UE而言只需要根据多次发射的随机接入资源中的一个随机接入资源就可以确定出多个下行控制信息加扰时所使用的同一个扰码值，减少了UE的检测复杂度。
需要说明的是，对于前述的各方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本申请并不受所描述的动作顺序的限制，因为依据本申请，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作和模块并不一定是本申请所必须的。
