背景技术
在5G新空口(NR，New Radio)的非授权频谱上，基站通过发射前监听(LBT，Listen Before Talk)获得传输机会(TXOP，Transmission Opportunity)。基站会发送初始信号给UE，告诉用户设备(UE，User Equipment)基站获得了TXOP。UE成功检测到了初始信号(Initial Signal)，知道基站获得了传输机会，开始一系列行为，例如监听物理下行控制信道(PDCCH，Physical Downlink Control Channel)等。初始信号又可以被称为前导(Preamble)信号，或者唤醒信号(WUS，Wake-Up Signal)。UE在激活时间(active time)时间内默认检测初始信号，只有检测到初始信号才开始监听PDCCH。这样初始信号又有省电的功能。因此，也可以被称为省电信号(Power Saving Signal)。

在5G系统中同步信号、广播信道是以同步信号块的方式发送的，并且引入了扫波束的功能。主同步信号(PSS，Primary Synchronization Signal)，辅同步信号(SSS，Secondary Synchronization Signal)和物理广播信道(PBCH，Physical Broadcast Channel)在SS/同步信号块(PBCH block)中。每个同步信号块可以看作是扫波束(beam sweeping)过程中的一个波束(模拟域)的资源。多个同步信号块组成一个同步信号突发(SS-burst)。SS-burst可以看作是包含了多个波束的相对集中的一块资源。多个同步信号突发组成一个同步信号突发集合(SS-burst-set)。PBCH block在不同波束上重复发送，是一个扫波束的过程，通过扫波束的训练，UE可以感知在哪个波束上收到的信号最强。比如，L个同步信号块在一个5ms窗口内的时域位置是固定的。L个同步信号块的索引在时域位置上是连续排列的， 从0到L-1，L为大于1的整数。因此一个同步信号块在这个5ms窗口内的发射时刻是固定的，索引也是固定的。
二、授权辅助接入(LAA，Licensed Assisted Access)中的发现参考信号(DRS，Discovery Reference Signal)：
在LTE Release 12中定义了DRS，用于用户设备对辅小区(SCell，Secondary Cell)的同步时频跟踪和测量，可以称为SCell的“发现”功能。采用DRS的好处是DRS是长周期信号，长周期信号对整个网络的干扰较小。DRS由PSS/SSS/CRS组成，其中CRS为小区指定参考信号(Cell-specific Reference Signal)。对于FDD系统，DRS持续时间(Duration)为1到5个连续子帧(subframe)；对于TDD系统，DRS持续时间为2到5个连续子帧。DRS的发射时机由发现测量时间配置(DMTC，Discovery Measurement Timing Configuration)定义，UE假设DRS在每个DMTC周期内出现一次。
在LTE的LAA中，DRS正好可以用于非授权频谱上的SCell的发现功能，因为其长周期特性，对减少对LAA系统和共享非授权频谱的异系统(如Wifi系统)的干扰。LAA DRS的持续时间为一个非空子帧内的12个正交频分复用(OFDM，Orthogonal Frequency Division Multiplexing)符号，以进一步减少对LAA系统和异系统的干扰。LAA DRS同样包括PSS/SSS/CRS。
LAA DRS的出现时机有两种情况：
情况一：UE可能假设LAA DRS可能出现在DMTC中的任一子帧中，并且UE可能假设LAA DRS出现在DMTC中包含一个PSS，一个SSS和CRS的第一个子帧上。也就是说，UE假设：在DMTC内基站进行LBT，如果监听到信道空闲，那么基站在一个非空子帧上发送一个DRS。
情况二：当LAA DRS与PDSCH/PDCCH/EPDCCH一起传输时，LAA DRS可能仅在子帧0和子帧5出现。也就是说，如果DMTC包含子帧0或5，并且用户设备在子帧0或5上需要检测PDCCH/EPDCCH或接收PDSCH，那么用户设备假设DRS只在子帧0或5上出现。
三、5G中的剩余最小系统信息(RMSI)：
5G中的RMSI相当于LTE中的SIB1，其包括除了MIB外的主要的系统信息。RMSI是在PDSCH里承载的，而PDSCH是通过PDCCH调度的。承载RMSI的PDSCH一般被称为RMSI PDSCH，调度RMSI PDSCH的PDCCH一般被称为RMSI PDCCH。
一般地，搜索空间集合(search space set)包含PDCCH的监测时机、搜索空间类型等性质。Search space set一般会绑定控制资源集合(CORESET)，并且，CORESET包含PDCCH的频域资源和持续时间等性质。
RMSI PDCCH所在的search space set一般被称为Type0-PDCCH search space set。一般地，它是由MIB配置的，或者切换等情形下由RRC配置的。Type0-PDCCH search space set被称为search space 0(或search space set 0)，所绑定的CORESET被称为CORESET 0。除了RMSI PDCCH的search space set，其他的公共搜索空间或公共搜索空间集合，如OSI PDCCH的search space set(Type0A-PDCCH search space set)、RAR PDCCH的search space set(Type1-PDCCH search space set)、paging PDCCH的search space set(Type2-PDCCH search space set)等，可以默认地与search space set 0相同。一般地，上述公共搜索空间或公共搜索空间集合都可以被重新配置。
四、同步信号块的LBT：
在NR的非授权频谱上，需要定义同步信号块，以便用户设备能够在小区搜索中检测到NR非授权频谱小区。同步信号块可以包含在DRS中，DRS作为包含同步信号块的一个整体；或者不定义DRS，同步信号块独立存在。
在NR非授权频谱上，基站发送DRS或同步信号块前需要进行LBT，只有当监听到信号空闲后，才发送DRS或同步信号块，否则在某一段时间后，基站再进行LBT。发送DRS或同步信号块是在某个发送窗口内进行的，该发送窗口可以是基站和用户设备约定好的，也可以是RRC信令通过DMTC或者同步测量时间配置(SMTC，Synchronization Measurement Timing Configuration)配置的。
由于需要进行LBT，所以DRS或同步信号块需要向后平移一定的时间。为了支持非授权频谱上的DRS或同步信号块向后平移的特性，DRS或同步信号块需要有多个预定义的时域位置。
五、RMSI的LBT：
在NR的非授权频谱上，基站发送RMSI前也可能需要进行LBT，只有当监听到信号空闲后，才发送RMSI，否则在某一段时间后，基站再进行LBT。发送RSMI是在某个发送窗口内进行的，该发送窗口可以是基站和UE约定好的，也可以是MIB或无线资源控制(RRC，Radio Resource Control))信令配置的。
由于需要进行LBT，所以RMSI需要向后平移一定的时间。为了支持非授权频谱上的RMSI向后平移的特性，RMSI需要有多个预定义的时域位置。
综上所述，对于初始信号，在NR的非授权频谱上，基站通过LBT获得TXOP后会发送初始信号，告诉UE基站获得了TXOP。通常UE在成功检测到初始信号后，需要监听某一种或多种类型的PDCCH来得到COT结构。这一种或多种类型的PDCCH可以通过search space set来配置。COT结构包括基站占据信道的持续时间(比如几毫秒，或几个时隙等等)、在持续时间内时隙的格式(比如上行、下行、灵活符号的配置)、在持续时间内可用的子信道(sub-channel)或子带(subbband)，其中，subbband是LTB的基本单位，例如20MHz带宽)等。
采用如下实施例，在NR非授权频谱里，UE在成功检测到初始信号后，可以确定监听的一种或多种类型的PDCCH，以根据PDCCH获得COT结构。
图1示出了本公开一实施例的初始信号处理方法流程示意图。如图1所示，该流程包括：
步骤S101、UE在非授权频谱里检测到初始信号后，确定需要监听的一种或多种PDCCH候选。
在一种可能的实现方式中，所述一种或多种PDCCH候选的类型包括：第一类PDCCH候选和调度PDCCH候选。
在一种可能的实现方式中，所述方法还包括：所述UE通过所述第一类PDCCH候选对COT结构进行指示。COT结构是指基站获得信道后所采用的结构，包括时域和频域结构，时域结构可以包括帧结构、时隙结构和/或符号的类型(包括上行、下行和灵活等)等，频域结构可以包括占用子带和/或占用PRB的情况等。
一个示例中，就PDCCH频域位置而言，UE在成功检测到初始信号，确定需要监听的第一类PDCCH候选。进一步，UE通过监听第一类PDCCH候选获得第一类下行控制信息(DCI，Downlink Control  Information)，UE通过第一类DCI确定需要监听的PDCCH候选。或者，UE在成功检测到初始信号，直接确定需要监听的PDCCH候选，包括了第一类PDCCH候选。
图2示出了本公开一实施例的初始信号处理方法流程示意图。如图2所示，该流程包括：
步骤S201、UE在非授权频谱里检测到初始信号。
步骤S202、UE通过监听第一类PDCCH候选获得第一类DCI，通过所述第一类DCI确定需要监听的一种或多种PDCCH候选。
在一种可能的实现方式中，除了上述步骤S101中，是根据初始信号直接确定需要监听的一种或多种PDCCH候选，简单来说，还包括一实现方式：根据初始信号找到第一类DCI，之后根据第一类DCI确定候选PDCCH，如根据第一类DCI确定CORESET；根据第一类DCI确定search space set；根据第一类DCI确定BWP。另一种实现方式是与上述步骤S101相结合的方式，如：根据初始信号找到第一类DCI，第一类DCI指示子带，则根据第一类DCI确定子带后，根据第一类DCI确定候选PDCCH。
具体的，所述UE通过所述第一类DCI确定需要监听的所述PDCCH候选，包括：检测到所述初始信号后，确定第一类DCI。根据所述第一类DCI确定所有候选的CORESET后，确定需要监听的PDCCH候选。其中，CORESET可以定义基本的时频域资源。
具体的，所述UE通过所述第一类DCI确定需要监听的所述PDCCH候选，包括：检测到所述初始信号后，确定第一类DCI。根据所述第一类DCI确定所有候选的search space set后，确定需要监听的PDCCH候选。
具体的，所述UE通过所述第一类DCI确定需要监听的所述PDCCH候选，包括：检测到所述初始信号后，确定第一类DCI。根据所述第一类DCI确定所有候选的部分带宽(BWP，Bandwidth Part)后，确定需要监听的PDCCH候选。
在一种可能的实现方式中，检测到所述初始信号后直接确定需要监听的所述PDCCH候选中包括：所述第一类PDCCH候选。
在一种可能的实现方式中，所述方法还包括：当在一个或多个子带内检测到所述初始信号后，确定需要监听的PDCCH候选的频域资源在子带内。
一个示例中，UE在某一个子带内成功检测到初始信号后，确定需要监听的PDCCH的频域资源在该子带内。这种通过频域资源关系确定需要监听的PDCCH的方式，适合组公共PDCCH(GC-PDCCH，Group Common-PDCCH)，组公共PDCCH表示某一组UE需要检测的PDCCH，或该PDCCH对应的DCI内容对于某一组UE是公共的，因为某一组UE可以使用公共的频域资源。
在一种可能的实现方式中，所述当在一个或多个子带内检测到所述初始信号后，确定需要监听的PDCCH候选的频域资源在子带内，还包括：所述UE在子带内检测到所述初始信号后，确定所有候选的PDCCH的过程中，若PDCCH候选的频域资源包含在所述子带内，则所述UE确定需要监听所述PDCCH候选。
一个示例中，UE在某一个子带内成功检测到初始信号后，检验所有可能的PDCCH候选(PDCCH candidate)，如果某个PDCCH候选的频域资源包含在该子带内，那么UE认为该PDCCH候选是需要检测的。
在一种可能的实现方式中，所述当在一个或多个子带内检测到所述初始信号后，确定需要监听的PDCCH的频域资源在子带内，还包括：所述UE在子带内检测到所述初始信号后，确定所有候选的CORESET的过程中，若CORESET包含在所述子带内，则所述UE确定需要监听所述CORESET内的PDCCH候选。
一个示例中，UE在某一个子带内成功检测到初始信号后，检验所有可能的CORESET，如果某个CORESET包含在该子带内，那么UE认为该CORESET内的PDCCH是需要检测的。所述“所有可能的CORESET”，可以是当前激活BWP(active BWP)内的所有CORESET，也可以是所有被配置的BWP(configured BWPs)内的所有CORESET。CORESET是关联到search space set(主要配置UE需要监听的PDCCH的时机，或者UE需要监听的PDCCH的时域位置)上的，即一个给定的search space set必定关联到一个CORESET上。不同的search space set可以关联到同一个CORESET上，或者换言之一个CORESET可以“包含”或关联多个search space set。所以上述方案更一般的描述为：UE在某一个子带内成功检测到初始信号后，检验所有search space set，如果某个search space set关联的某一个CORESET包含在该子带内，那么UE认为该search space set内的PDCCH是需要检测的。
在一种可能的实现方式中，所述当在一个或多个子带内检测到所述初始信号后，确定需要监听的PDCCH的频域资源在子带内，还包括：所述UE在子带内检测到所述初始信号后，确定所有候选的search space set的过程中，若search space set所关联的CORESET包含在所述子带内，则UE确定需要监听所述search space set。
在一种可能的实现方式中，所述当在一个或多个子带内检测到所述初始信号后，确定需要监听的PDCCH的频域资源在子带内，还包括：所述UE在子带内检测到所述初始信号后，确定所有候选的BWP。若BWP包含在所述子带内，则UE确定所述BWP被激活。
在一种可能的实现方式中，所述方法还包括：UE确定所述检验得到的BWP被激活后，所述UE确定所述BWP内所有配置于search space set内的PDCCH需要被检测。
一个示例中，UE在某一个子带内成功检测到初始信号后，检验所有被配置的BWP，如果某个BWP包含在该子带内，那么UE认为该BWP被激活，并且UE认为该BWP内的所有配置的search space set内的PDCCH是需要检测的。一般来说，当一个BWP被激活，该BWP内的所有配置的search space set内的PDCCH是需要检测的。
在一种可能的实现方式中，所述当在一个或多个子带内检测到所述初始信号后，确定被调度的PDSCH的PRB索引为所述一个或多个子带内的PRB顺序排列后的索引。上述可能的实现方式，适用于上述示例中在一个子带内成功检测到初始信号的情况，当在多个子带内成功检测到初始信号，上述实现方式仍然适用。
在一种可能的实现方式中，所述方法还包括：所述UE在检测到一个或多个初始信号后，确定需要监听的PDCCH候选与初始信号关联的PDCCH候选。其中，当所述初始信号为多个时，所述UE只监听多个初始信号中与每一个初始信号相关联的PDCCH候选。这种通过关联关系确定需要监听的PDCCH的方式，适合UE specific PDCCH，即该PDCCH对应的DCI内容只针对某一个UE。
在一种可能的实现方式中，所述UE在检测到一个或多个初始信号后，确定需要监听的PDCCH候 选与初始信号关联的PDCCH候选，还包括：所述UE在检测到所述初始信号后，监听与所述初始信号相关联的PDCCH候选。

一个示例中，UE在成功检测到某个初始信号后，确定该初始信号相关联的CORESET ID，UE只需要监听的相关联的CORESET内的PDCCH候选。更一般的描述为：UE在成功检测到某个初始信号后，确定该初始信号相关联的CORESET ID，UE只需要监听的相关联的CORESET所关联的search space set内的PDCCH候选。
在一种可能的实现方式中，所述UE在检测到一个或多个初始信号后，确定需要监听的PDCCH候选与初始信号关联的PDCCH候选，还包括：所述UE在检测到所述初始信号后，确定所述初始信号相关联的CORESET ID。所述UE只监听所述相关联的CORESET所关联的search space set内的PDCCH候选。

图3示出了本公开一实施例的初始信号处理方法流程示意图。如图3所示，该流程包括：
步骤S301、所述UE在非授权频谱里检测到初始信号后，根据所配置的监听时机监听一种或多种PDCCH。
区别于上述实施例，引入了监听时机，即是根据所配置的监听时机来监听一种或多种PDCCH。

在一种可能的实现方中，所述方法还包括：所述UE通过所述第一类PDCCH候选对COT结构进行指示。COT结构是指基站获得信道后所采用的结构，包括时域和频域结构，时域结构可以包括帧结构、时隙结构和/或符号的类型(包括上行、下行和灵活等)等，频域结构可以包括占用子带和/或占用PRB的情况等。
图4示出了本公开一实施例的初始信号处理方法流程示意图。如图4所示，该流程包括：
步骤S401、所述UE在非授权频谱里检测到初始信号。
步骤S402、当前时隙不是完整时隙，则在当前时隙的剩余符号里按照RRC配置的监听时机配置，或在所述当前时隙的后续完整时隙里按照RRC配置的监听时机配置，监听PDCCH候选。
具体是根据所配置的监听时机对所述第一类PDCCH候选进行监听。本公开中的监听时机配置指在search space set中配置的PDCCH监听时机，由search space set配置中的参数指定。
在一种可能的实现方式中，所述监听时为第一类PDCCH候选的所述监听时时，对所述第一类PDCCH候选进行监听。
在一种可能的实现方式中，所述UE根据所配置的监听时机对所述第一类PDCCH候选进行监听，还包括如下三种实现方式的至少一种组合：
方式一：所述UE在检测到所述初始信号后，若当前时隙不是完整时隙，则在当前时隙的剩余符号里基于默认的方式进行第一类PDCCH候选的监听。
方式二：所述UE在检测到所述初始信号后，若当前时隙不是完整时隙，则在当前时隙的后续完整时隙里按照RRC配置的监听时机，监听PDCCH候选。所述监听时机配置为第一类PDCCH候选的监听时机配置时，对所述第一类PDCCH候选进行监听。
在一种可能的实现方式中，所述UE根据所配置的监听时机对所述第一类PDCCH候选进行监听，还包括：所述UE在检测到所述初始信号后，若当前时隙不是完整时隙，则在当前时隙的剩余符号里按照RRC配置的用于部分时隙的时隙，监听所配置的PDDCH候选。所述监听时机配置为第一类PDCCH候选的监听时机配置时，对所述第一类PDCCH候选进行监听。
在一种可能的实现方式中，所述方法还包括：在当前时隙的后续完整时隙按照RRC配置的监听时机配置，监听PDCCH候选。所述监听时机配置为第一类PDCCH候选的监听时机配置时，对所述第一类PDCCH候选进行监听。
方式三：在一种可能的实现方式中，所述UE根据所配置的监听时机对所述第一类PDCCH候选进行监听，还包括：所述UE在检测到所述初始信号后，若当前时隙不是完整时隙，则不需要在当前时隙内进行第一类PDCCH候选的监听。在当前时隙的后续完整时隙里按照RRC配置的监听时机，监听PDCCH候选。所述监听时机配置为第一类PDCCH候选的监听时机配置时，对所述第一类PDCCH候选进行监听。
对于第一类PDCCH候选的监听的一个示例中：
UE在成功检测到初始信号后，如果当前时隙不是“完整时隙”，在当前时隙的剩余符号里，按照RRC配置的监听时机配置(第一类PDCCH候选的search space set配置)，进行第一类PDCCH候选的监听。在后续完整时隙里，按照RRC配置的监听时机配置(第一类PDCCH候选的search space set配置)， 进行第一类PDCCH候选的监听。
UE在成功检测到初始信号后，如果当前时隙不是完整时隙，在当前时隙的剩余符号里，按照默认的方式，进行第一类PDCCH候选的监听，例如默认每两个符号的第一个符号为PDCCH监听时机的开始符号。在后续完整时隙里，按照RRC配置的监听时机配置(第一类PDCCH候选的search space set配置)，进行第一类PDCCH候选的监听。
UE在成功检测到初始信号后，如果当前时隙不是完整时隙，在当前时隙的剩余符号里，按照RRC配置的专门用于“部分时隙”的监听时机配置(第一类PDCCH候选的search space set配置)，进行第一类PDCCH候选的监听。在后续完整时隙里，按照RRC配置的监听时机配置(第一类PDCCH候选的search space set配置)，进行第一类PDCCH候选的监听。
UE在成功检测到初始信号后，如果当前时隙不是完整时隙，不需要在当前时隙内进行第一类PDCCH候选的监听。在后续完整时隙里，按照RRC配置的监听时机配置(第一类PDCCH候选的search space set配置)，进行第一类PDCCH候选的监听。
在一种可能的实现方式中，所述方法还包括：所述UE根据所配置的监听时机对所述调度PDCCH候选进行监听。
在一种可能的实现方式中，所述UE根据所配置的监听时机对所述调度PDCCH候选进行监听，还包括：若所述UE没有检测到所述第一类PDCCH候选，则所述UE按照RRC配置的监听时机配置，监听PDCCH候选，根据所述监听时机配置对所述调度PDCCH进行监听。
在一种可能的实现方式中，所述UE根据所配置的监听时机对所述调度PDCCH候选进行监听，还包括：若所述UE没有检测到所述第一类PDCCH候选，则所述UE不需要对所述调度PDCCH进行监听，直到检测到所述第一类PDCCH候选。
在一种可能的实现方式中，所述方法还包括：所述UE获取第一类DCI的指示信息对应的起始时隙位置。
在一种可能的实现方式中，所述UE获取第一类DCI的指示信息对应的起始时隙位置，还包括：当前时隙(即检测到第一类PDCCH所在时隙)为第一类DCI的指示信息对应的起始时隙。这种方式适合指示信息针对的是当前时隙和后续时隙，好处是节省开销。
在一种可能的实现方式中，所述UE获取第一类DCI的指示信息对应的起始时隙位置，还包括：若当前时隙的索引是n，当前时隙是COT结构里的第k个时隙，则所述第一类DCI的指示信息对应的起始时隙索引为：n-k。其中，k>＝0。其中，k为指示给UE的当前时隙在COT结构中的索引。n是当前时隙的索引，或者检测到第一类PDCCH所在时隙。UE反推COT结构中的开始的时隙的索引是n-k。这种方式适合指示信息针对的是当前时隙或其之前的某个时隙为开始时隙的情形，好处是指示信息可以出现多次，每次都是针对同一个开始时隙。
在一种可能的实现方式中，所述UE获取第一类DCI的指示信息对应的起始时隙位置，还包括：若当前时隙的索引在一个时隙格式(SF，Slot Format)周期(也称时隙格式指示周期)中，则所述第一类DCI的指示信息对应的起始时隙为：所述时隙格式周期中的第一个时隙。其中，所述时隙格式周期由RRC信令进行指示。这种方式适合指示信息针对的是某个半静态配置的时隙为开始时隙的情形，适 合周期性的时隙格式。
对于调度PDCCH候选的监听的一个示例中：
如果UE没有成功检测到第一类PDCCH候选，那么UE按照RRC配置的监听时机配置，进行调度PDCCH的监听。
如果UE没有成功检测到第一类PDCCH候选，那么UE不需要进行调度PDCCH的监听，直到成功检测到第一类PDCCH候选。
这里，定义第一类DCI的指示信息为包含COT结构信息，或时隙格式指示(SFI，Slot Format Indicator)，或两者的指示信息。第一类DCI的指示信息可以指示“灵活”时隙或符号，“下行”时隙或符号，“上行”时隙或符号。一般来说，UE仅仅在下行符号上才监听PDCCH候选，所以第一类DCI的指示信息是比较重要的。
在一种可能的实现方式中，第一类DCI的指示信息中的COT结构信息可以覆盖时隙格式指示的信息。例如，当时隙格式指示的信息指示某个符号为“灵活”类型，第一类DCI的指示信息中的COT结构信息可以将之修改为“下行”类型。
第一类DCI的指示信息里包括了从某个时隙开始的连续多个时隙的信息，例如基站占据信道的持续时间、在持续时间内时隙的格式等。一般来说，UE需要知道第一类DCI的指示信息对应的起始时隙位置，才能推导出连续多个时隙的信息。
UE如何获取第一类DCI的指示信息对应的起始时隙位置，包括如下三种方法：
方法1：
当前时隙(即检测到第一类DCI的时隙)为第一类DCI的指示信息对应的起始时隙。
方法2：
当前时隙的索引是n，并且当前时隙是COT结构里的第k个时隙，那么第一类DCI的指示信息对应的起始时隙的索引是(n-k)。
方法3：
当前时隙的索引在第m个时隙格式周期中(时隙格式周期由RRC信令指示)，那么第一类DCI的指示信息对应的起始时隙是第m个时隙格式周期中的第一个时隙。

在一种可能的实现方式中，所述第二监听子单元，进一步用于：在子带内检测到所述初始信号后，确定所有候选的search space set的过程中，若search space set所关联的CORESET包含在所述子带内，则确定需要监听所述search space set。
