在第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)正在进行的5G的标准化过程中，考虑最大支持到400MHz的载波带宽。然而，对于终端侧，由于受制于各种不同类型终端设备的成本，不是所有的终端设备都能够支持400MHz带宽的通信、测量等操作。同时为了系统实现和调度的灵活性，在5G的讨论过程中同意在一个宽的带宽上，网络侧发送多个同步信号块(Synchronization Signal block，SS block，SSB)，以便终端设备在不同的SSB上做测量或初始接入。
在一个带宽上的多个SSB中有些SSB没有关联其余系统消息(Remaining System Information，RMSI)。终端设备在初始接入的时候，由于没有任何预先的信息，所以终端设备在入网之前不知道哪个SSB上关联RMSI。因此终端设备需要对每个SSB所在的同步频率的频点分别去做同步搜索和系统消息的检测。终端设备在检测到当前的SSB上没有关联RMSI时，再依次去检测下一个候选的同步频点。这样会增加终端设备的检测复杂度和入网(成功检测到RMSI)的时延。
因此，在一个带宽上有多个SSB灵活配置的系统中，如何有效地降低终端设备的检测复杂度成为一个亟待解决的技术问题。

本发明实施例中的通信设备可以为终端设备。终端设备也可以指用户设备(User Equipment，UE)、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。接入终端可以是蜂窝电话、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、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的终端设备等。
作为示例而非限定，在本发明实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及通过专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
本发明实施例中的通信设备可以为网络设备。网络设备可以是用于与终端设备通信的设备，该网络设备可以是全球移动通讯(Global System of Mobile communication，GSM)或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统中的基站(NodeB，NB)，还可以是长期演进(Long Term Evolution，LTE)系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等。
另外，在本发明实施例中，网络设备为小区提供服务，终端设备通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与网络设备进行通信，该小区可以是网络设备(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(small cell) 对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。另外，该小区还可以是超小区(Hypercell)。
图3为举例地可以应用本发明实施例的一种网络架构示意图，该网络架构示意图可以是下一代无线通信系统中的新无线接入(New Radio Access，NR)的网络架构图。在该网络架构示意图中，网络设备可以被分为一个集中式单元(centralized unit，CU)和多个传输接收点(transmission reception point，TRP)/分布式单元(distributed unit，DU)，即网络设备的基于带宽的单元(bandwidth based unit，BBU)被重构为DU和CU功能实体。需要说明的是，集中式单元、TRP/DU的形态和数量并不构成对本发明实施例的限定。图2所示的网络设备1和网络设备2各自对应的集中式单元的形态虽然有所不同，但是并不影响各自的功能。可以理解的是，集中式单元1和虚线范围内的TRP/DU是网络设备1的组成元素，集中式单元2和实线范围内的TRP/DU是网络设备2的组成元素，网络设备1和网络设备2为NR系统中涉及的网络设备(或称为基站)。
CU可以处理无线高层协议栈功能，例如无线资源控制(radio resource control，RRC)层，分组数据汇聚层协议(Packet Data Convergence Protocol，PDCP)层等，甚至也能够支持部分核心网功能下沉至接入网，术语称作边缘计算网络，能够满足未来通信网络对于新兴业务例如视频，网购，虚拟/增强现实对于网络时延的更高要求。
DU可以主要处理物理层功能和实时性需求较高的层2功能，考虑到无线远端单元(radio remote unit，RRU)与DU的传输资源，部分DU的物理层功能可以上移到RRU，伴随RRU的小型化，甚至更激进的DU可以与RRU进行合并。
CU可以集中式的布放，DU布放取决实际网络环境，核心城区，话务密度较高，站间距较小，机房资源受限的区域，例如高校，大型演出场馆等，DU也可以集中式布放，而话务较稀疏，站间距较大等区域，例如郊县，山区等区域，DU可以采取分布式的布放方式。
图3所举例的S1-C接口，可以为网络设备与核心网之间的标准接口，具体S1-C所连接的设备未在图3中示出。
图4示出了本发明实施例的同步信号块的结构的示意图。应理解，图4仅是示例，不构成对本发明实施例的限定。
如图4所示，同步信号，包括主同步信号(primary synchronization signal，PSS)和辅同步信号(secondary synchronization signal，SSS)，与物理广播信道(Physical Broadcast Channel，PBCH)可一起组成一个SSB，即，NR主同步信号(NR-PSS)，NR辅同步信号(NR-SSS)和NR物理广播信道(NR-PBCH)在一个SSB里发送。为了简洁，同步信号块中的NR-PSS、NR-SSS和NR-PBCH可以分别简称为PSS、SSS和PBCH。
另外，多个SSB可构成一个同步信号脉冲集(SS burst set)，SS burst set周期性地发送。也就是说，网络设备发送SSB的方式是采用周期性的SS burst set发送方式，每个SS burst set中包括多个SSB。
例如，图9是同步信号块的一种可能结构的示意图。PSS和SSS主要作用是帮助UE识别小区以及和小区进行同步，PBCH则包含了最基本的系统信息例如系统帧号、 帧内定时信息等。UE成功接收同步信号块是其接入该小区的前提。每个SSB持续4个符号，其中，PSS占据第1个符号，PBCH占据第2个符号，PBCH、SSS、PBCH占据第3个符号，PBCH占据第4个符号。
剩余最小系统消息(remaining minimum system information，RMSI)，承载于下行共享物理信道(physical downlink shared channel，PDSCH)，承载RMSI的PDSCH通过承载RMSI调度信息的物理下行控制信道(physical downlink control channel，PDCCH)来调度。SSB中的PBCH包括用于找到所述承载RMSI调度信息的PDCCH的一些基本信息。为了便于终端执行对于携带RMSI调度的PDCCH的盲检测时，SSB中的PBCH需要提供承载RMSI调度信息的PDCCH的搜索空间(Type0-PDCCH common search space)的一些信息。
应理解，本发明实施例对同步信号块和同步信号脉冲集的名称并不限定，也就是说，它们也可以表述为其他名称。例如，SSB也可以表述为SS/PBCH block。
图5示出了一个带宽上配置有多个SSB的示意图。应理解，图5仅是示例，不构成对本发明实施例的限定。
如图5所示，在一个带宽上的3个SSB中，SSB3关联RMSI，SSB1和SSB2没有关联RMSI。终端设备在没有任何信息的条件下，需要对每个SSB1，SSB2和SSB3所在的同步频率的频点分别去做同步搜索和RMSI的检测。终端设备在检测到当前的SSB上没有关联RMSI时，再依次去检测下一个候选的同步频点。这样会大大地增加终端设备的检测复杂度和入网的时延。
鉴于此，本发明实施例提供了一种技术方案，可以减少终端设备的盲检，降低终端设备的检测复杂度，减少终端设备的功耗和时延。
应理解，上述RMSI还可以变换为其他控制信息。另外，本发明实施例的技术方案除了可以应用于蜂窝和中继场景外，还可以应用于D2D场景。在本发明实施例中以控制信息为例进行描述。对于蜂窝和中继场景，该控制信息可以为系统消息(system information，SI)，如RMSI，或其它系统消息(other system information，OSI)。对于D2D场景，该控制信息为发送端调度接收端进行数据接收的控制信息。但本发明实施例对此并不限定。
还应理解，对于蜂窝和中继场景，本发明实施例中的物理广播信道可以为PBCH，同步信号标识可以为物理小区标识。对于D2D场景，本发明实施例中的物理广播信道可以为物理副链路广播信道(Physical Sidelink Broadcast Channel，PSBCH)，同步信号标识可以为D2D链路的同步信号区标识。但本发明实施例对此并不限定。
还应理解，SSB与控制信息的关联可以包括但不限定为以下方式：
方式一：该关联表示按协议规定的方式或预定义的方式在与SSB相同的时域资源上或在SSB后续的时域资源上有控制信息在发送。这个后续的时域资源与SSB有一定的时间上的对应关系。例如：与SSB相邻，或间隔一定的时长。
方式二：该关联为通过SSB中的物理广播信道来指示终端设备所关联的控制信息的资源配置信息。如该控制信息的资源池的位置，或该控制信息的指示信息的配置等。
图6示出了本发明一个实施例的通信的方法的示意性流程图。图6中的第一设备为 发送设备，例如可以为前面描述的网络设备或终端设备；第二设备为接收设备，例如可以为前面描述的终端设备。
610，第一设备确定第一指示信息，其中，该第一指示信息指示第二同步信号块的资源位置，该第二同步信号块关联控制信息。
在本发明实施例中，第一设备在发送同步信号块(表示为第一同步信号块)时，会确定关联控制信息的同步信号块(表示为第二同步信号块)的资源位置，进而在第一同步信号块中将第二同步信号块的资源位置指示给第二设备。
应理解，资源位置可以包括：时域位置，或频域位置或者时频位置。例如，在该第一指示信息指示时域位置时，表明第二同步信号块与第一同步信号块可以不在同一个时隙上。以下以频域位置为例进行说明，但本发明实施例对此并不限定。
可选地，该第二同步信号块的资源位置可以为该第二同步信号块在带宽中的绝对位置或相对于该第一同步信号块的相对位置。
例如，该第一指示信息可以指示第二同步信号块与第一同步信号块的频率偏移值，或者，该第一指示信息可以指示第二同步信号块在当前载波中的物理资源块(Physical Resource Block，PRB)的频率位置。
应理解，第二同步信号块与第一同步信号块可以相同，即，这种情况为第一同步信号块关联该控制信息的情况。相应地，在这种情况下，该第一指示信息指示的时域资源或频域资源的相对偏差值为0，或者指示的在带宽中绝对位置为第一同步信号块的位置。
可选地，第一设备可以在该第一同步信号块不关联该控制信息时，确定该第一指示信息。
也就是说，在该第一同步信号块关联该控制信息，可以不需要该第一指示信息。在该第一同步信号块不关联该控制信息时，第一设备配置该第一指示信息。
620，第一设备发送第一同步信号块，其中，该第一同步信号块中的物理广播信道携带该第一指示信息。
第一设备将该第一指示信息携带在该第一同步信号块中的物理广播信道中发送给第二设备。
可选地，在本发明一个实施例中，该第一指示信息可以携带于该物理广播信道的预留字段中。
将该第一指示信息可以携带于预留字段中，对其他字段没有影响，对物理广播信道的改动较小。
可选地，在本发明一个实施例中，可以对物理广播信道重新设置。例如，该物理广播信道可以包括三部分字段，其中，
第一字段仅在该第一同步信号块关联该控制信息时有效；
第二字段仅在该第一同步信号块不关联该控制信息时有效，该第二字段携带该第一指示信息；
第三字段在该第一同步信号块关联或不关联该控制信息时皆有效。
可选地，该第一字段和该第二字段在该物理广播信道占用的比特位部分或完全重叠。
例如，如图7所示，字段1和字段2在SSB关联或不关联控制信息时皆有效，为 上述第三字段；字段3-6在SSB关联控制信息时有效，为上述第一字段；字段3’和字段4’在SSB不关联控制信息时有效，为上述第二字段，可以在字段3’和字段4’携带该第一指示信息。
也就是说，在当前的SSB不关联控制信息时，物理广播信道字段中除了一部分测量时必须要用到的字段之外，其他字段会失效，在其它字段失效后，余下来的比特可以重新配置为新的字段，用于携带该第一指示信息。
以PBCH为例，SSB不关联控制信息时，PBCH中除超帧号(hyper frame number，HFN)，SSB时间序号(SSB time index)外，原有其他字段，如“RMSI控制资源”、“同步信号在PRB内的子载波偏移值”、“系统帧号(system frame number，SFN)”等会失效，失效后的字段留出来的PBCH比特可以用来携带该第一指示信息。
上述方案能够提供足够的信息比特用于指示第二同步信号块的资源位置。
对于一个做8192点快速傅里叶变换(Fast Fourier Transformation，FFT)的正交频分复用(orthogonal frequency division multiplexing,OFDM)系统，假设一个PRB占用12个子载波，最多有8192/12＝682个PRB。682个PRB最多使用10比特(指示最大1024个值)即可指示出所有的关联RMSI的SSB的PRB频率位置。
可选地，在本发明一个实施例中，该物理广播信道还携带第三指示信息，该第三指示信息指示该第一同步信号块的同步信号标识是否与该第二同步信号块的同步信号标识相同。
具体而言，在一些可能的设计中，该第一同步信号块的同步信号标识与该第二同步信号块的同步信号标识可能不同。在这种情况下，可以通过在物理广播信道中携带第三指示信息指示该第一同步信号块的同步信号标识是否与该第二同步信号块的同步信号标识相同。
可选地，在本发明一个实施例中，该物理广播信道还携带第四指示信息，该第四指示信息指示该第二同步信号块的同步信号标识。
具体而言，除了指示该第二同步信号块的资源位置外，还可以通过在物理广播信道中携带第四指示信息指示该第二同步信号块的同步信号标识。例如，在该第一同步信号块的同步信号标识与该第二同步信号块的同步信号标识不同的情况下，通过物理广播信道指示该第二同步信号块的同步信号标识，可以进一步降低第二设备的检测复杂度。
利用上述技术方案，第二设备在检测了该第一同步信号块之后，可以直接获知该第二同步信号块的资源位置，从而可以不用再做盲检，直接切到相应资源位置上做搜索，从而能够降低第二设备的检测复杂度，减少第二设备的搜索计算时间、功率消耗和时延。
可选地，第一设备还可以向第二设备指示该第一同步信号块是否关联该控制信息。
第一设备向第二设备指示该第一同步信号块是否关联该控制信息的方式可以是显式的方式，例如，通过相应的比特位指示；也可以是隐式的方式，例如，通过该第一同步信号块的传输方式指示，下面分别进行说明。
可选地，在本发明一个实施例中，该物理广播信道还携带第二指示信息，该第二指示信息指示该第一同步信号块是否关联该控制信息。
该实施例为显式指示的方式。例如，可以通过物理广播信道中的一个比特携带该第二指示信息，指示该第一同步信号块是否关联该控制信息。
可选地，在本发明一个实施例中，该第一设备还可以确定该第一同步信号块的传输方式，其中，该传输方式指示该第一同步信号块是否关联该控制信息；根据该传输方式发送该第一同步信号块。
该实施例为隐式指示的方式。该第一设备通过该第一同步信号块的不同的传输方式分别指示该第一同步信号块关联该控制信息或该第一同步信号块不关联该控制信息。
例如，该第一设备可以执行图8所示的流程。在801中，确定同步信号块是否关联控制信息，若是，则执行802，使用传输方式一发送该同步信号块，若否，则执行803，使用传输方式二发送该同步信号块。
可选地，该传输方式可以包括同步信号序列在频域中的映射方式、正交覆盖码(Orthogonal Coverage Code，OCC)、同步信号标识、物理广播信道的循环冗余校验(Cyclic Redundancy Check,CRC)掩码或者物理广播信道的加扰等，以下分别进行描述，但本发明实施例对此并不限定。
可选地，在本发明一个实施例中，该第一同步信号块的传输方式包括该第一同步信号块中的同步信号序列在频域中的映射方式；
该第一设备可以：
在该第一同步信号块关联该控制信息时，确定该映射方式为多种预定映射方式中的第一映射方式；和/或
在该第一同步信号块不关联该控制信息时，确定该映射方式为该多种预定映射方式中的第二映射方式。
具体而言，该第一设备可以根据该第一同步信号块是否关联该控制信息，确定该第一同步信号块中的同步信号序列在频域中的映射方式，针对关联或不关联，分别采用不同的映射方式。
例如，SSS或PSS的序列可以采用如图9所示的两种映射方式，SSS或PSS的序列从低频向高频映射为一种映射方式，可对应SSB关联了控制信息；SSS或PSS的序列从高频向低频映射为另一种映射方式，可对应SSB没有关联控制信息，反之亦然。
可选地，在本发明一个实施例中，该第一同步信号块的传输方式包括调制在该第一同步信号块的传输符号上的正交覆盖码的取值；
该第一设备可以：
在该第一同步信号块关联该控制信息时，确定该正交覆盖码的取值为多种预定取值中的第一取值；和/或
在该第一同步信号块不关联该控制信息时，确定该正交覆盖码的取值为该多种预取值中的第二取值。
具体而言，该第一设备可以根据该第一同步信号块是否关联该控制信息，确定调制在该第一同步信号块的传输符号上的正交覆盖码的取值，针对关联或不关联，分别采用不同的正交覆盖码的取值。
例如，可以采用如图10所示的不同正交覆盖码的取值，分别指示该第一同步信号块关联该控制信息或该第一同步信号块不关联该控制信息；或者可以采用如图11所示的不同正交覆盖码的取值，分别指示该第一同步信号块关联该控制信息或该第一同步信号块不关联该控制信息。在图10中，OCC调制在2个PBCH符号上，在图11中，调 制在PSS、PBCH、SSS和PBCH4个符号上，其中“+”表示对所有子载波上的数据或符号乘上+1，“-”表示对所有子载波上的数据或符号乘上“-1”。
可选地，在本发明一个实施例中，该第一同步信号块的传输方式包括该第一同步信号块使用的同步信号标识所属的范围；
该第一设备可以：
在该第一同步信号块关联该控制信息时，确定该第一同步信号块使用的同步信号标识属于第一子集；和/或
在该第一同步信号块不关联该控制信息时，确定该第一同步信号块使用的同步信号标识属于第二子集。
具体而言，在本实施例中，可以设置两个子集的同步信号标识，分别对应关联控制信息或不关联控制信息。例如，第一子集可以为同步信号块的同步信号标识(即实际的同步信号标识)的集合，第二子集可以为第一子集中的同步信号标识加上预定值后得到的同步信号标识的集合，其中，该预定值大于第一子集中的最大值与最小值的差。
例如，若实际的同步信号标识的集合为{0～503}，则第一子集可以为{0～503}，第二子集可以为{504～1007}；若实际的同步信号标识的集合为{0～1007}，则第一子集可以为{0～1007}，第二子集可以为{1008～2015}。
该第一同步信号块使用的同步信号标识可以属于上述第一子集，即采用该第一同步信号块的同步信号标识(即实际的同步信号标识)，也可以属于上述第二子集，即采用该第一同步信号块的同步信号标识(即实际的同步信号标识)与预定值的和。上述两种情况可分别对应关联控制信息或不关联控制信息。
即，该第一设备可以：
在该第一同步信号块关联该控制信息时，确定该第一同步信号块使用的同步信号标识为该第一同步信号块的同步信号标识，和/或，在该第一同步信号块不关联该控制信息时，确定该第一同步信号块使用的同步信号标识为该第一同步信号块的同步信号标识与预定值的和；或者，
在该第一同步信号块关联该控制信息时，确定该第一同步信号块使用的同步信号标识为该第一同步信号块的同步信号标识与预定值的和，和/或，在该第一同步信号块不关联该控制信息时，确定该第一同步信号块使用的同步信号标识为该第一同步信号块的同步信号标识；
其中，该预定值大于该第一同步信号块的同步信号标识的取值范围中的最大值与最小值的差。
对于该第一同步信号块使用的同步信号标识为该第一同步信号块的同步信号标识与预定值的和的情况，第二设备可以将检测到的该第一同步信号块使用的同步信号标识减去预定值后得到该第一同步信号块的同步信号标识，这样就不会影响第二设备的初始搜索的邻小区测量。
举例来说，若实际的同步信号标识的取值范围为{0～503}，则两个子集可以分别为{0～503}和{504～1007}。假设该第一同步信号块的同步信号标识为1，在该第一同步信号块关联该控制信息时，可以使用1；在该第一同步信号块不关联该控制信息时，可以使用505，第二设备可以通过将其减去预定值(504)后得到实际的同步信号标识1，反之 亦然。若实际的同步信号标识的取值范围为{0～1007}，则两个子集可以分别为{0～1007}和{1008～2015}。假设该第一同步信号块的同步信号标识为1，在该第一同步信号块关联该控制信息时，可以使用1；在该第一同步信号块不关联该控制信息时，可以使用1009，第二设备可以通过将其减去预定值(1008)后得到实际的同步信号标识1，反之亦然。
可选地，在本发明一个实施例中，该第一同步信号块的传输方式包括该第一同步信号块中的物理广播信道使用的CRC掩码；
该第一设备可以：
在该第一同步信号块关联该控制信息时，确定该CRC掩码为多种预定CRC掩码中的第一CRC掩码；和/或
在该第一同步信号块不关联该控制信息时，确定该CRC掩码为该多种预定CRC掩码中的第二CRC掩码。
具体而言，该第一设备可以根据该第一同步信号块是否关联该控制信息，确定该第一同步信号块中的物理广播信道使用的CRC掩码，针对关联或不关联，分别采用不同的CRC掩码。
例如，物理广播信道的CRC长度为16位时，可以使用“0000000000000000”和“0000000011111111”两种不同的CRC掩码来指示关联或不关联。
加CRC掩码的过程如下所示：
yc(n)＝(xc(n)+sc(n))mod 2,n＝0,1,..,N-1
其中，N为CRC的检验位数，xc表示原CRC检验位，sc为与CRC等长的掩码，yc为加完CRC之后的校验位。
可选地，在本发明一个实施例中，该第一同步信号块的传输方式包括该第一同步信号块中的物理广播信道采用的加扰序列；
该第一设备可以：
在该第一同步信号块关联该控制信息时，确定该加扰序列为多种预定加扰序列中的第一加扰序列；和/或
在该第一同步信号块不关联该控制信息时，确定该加扰序列为该多种预定加扰序列中的第二加扰序列。
具体而言，该第一设备可以根据该第一同步信号块是否关联该控制信息，确定该第一同步信号块中的物理广播信道采用的加扰序列，针对关联或不关联，分别采用不同的加扰序列。
例如，可以对物理广播信道编码前或编码后的信息或编码比特进行对应的加扰。使用不同的序列对应不同的状态(关联或不关联)。加扰的过程可以如下所示：
y(n)＝(x(n)+s(n))mod 2,n＝0,1,..,L-1
其中，L为物理广播信道的信息或编码比特长度，x表示加扰前的物理广播信道的信息或编码比特，s为加扰序列，y为加扰之后的物理广播信道的信息或编码比特。根据不同的状态生成不同的s。不同的状态可以对应不同的加扰序列，也可以对应不同的加扰序列的初始值。
采用上述技术方案，第二设备通过检测该第一同步信号块的实际的传输方式，从而确定该第一同步信号块是否关联了控制信息，不需要再盲检物理广播信道，从而能够降 低第二设备的检测复杂度，减少第二设备的功率消耗和时延。
630，第二设备获取该第一同步信号块中的物理广播信道携带的第一指示信息。
在接收侧，第二设备接收该第一同步信号块，获取其中的第一指示信息，从而可以直接获知该第二同步信号块的资源位置。
可选地，第二设备还可以先确定该第一同步信号块是否关联该控制信息。在确定该第一同步信号块不关联控制信息时，获取该第一同步信号块中的物理广播信道携带的第一指示信息。在确定该第一同步信号块关联该控制信息时，根据该第一同步信号块接收该控制信息。
对应于第一设备指示该第一同步信号块是否关联该控制信息的方式，第二设备可采用相应的方式确定该第一同步信号块是否关联该控制信息。
可选地，在该物理广播信道携带该第二指示信息时，第二设备可以根据该第二指示信息，确定该第一同步信号块是否关联该控制信息。

可选地，该第一同步信号块的传输方式包括该第一同步信号块使用的同步信号标识所属的范围；
第二设备可以：
在该第一同步信号块使用的同步信号标识属于第一子集时，确定该第一同步信号块关联该控制信息；和/或

可选地，该第一同步信号块的传输方式包括该第一同步信号块中的物理广播信道使用的CRC掩码；

可选地，该第一同步信号块的传输方式包括该第一同步信号块中的物理广播信道采用的加扰序列；

可选地，在该物理广播信道携带该第四指示信息，该第四指示信息指示该第二同步信号块的同步信号标识；第二设备可以根据该第四指示信息，确定该第二同步信号块的同步信号标识。
640，第二设备根据该第一指示信息接收该控制信息。
第二设备通过该第一指示信息，获知该第二同步信号块的资源位置，直接到相应资源位置上做搜索，接收该控制信息。
例如，该第二设备可以执行图12所示的流程。在1201中，检测同步信号块，确定同步信号块的传输方式，在1202中根据同步信号块的传输方式确定该同步信号块是否关联控制信息，若是，则执行1203，接收关联的该控制信息，若否，则执行1204，获取第一指示信息，根据该第一指示信息接收该控制信息。
本发明实施例的技术方案，通过向接收侧指示关联控制信息的同步信号块的资源位置，可以使得接收侧的终端设备直接获知该同步信号块的资源位置，从而可以不用再做盲检，直接切到相应资源位置上做搜索，从而能够降低终端设备的检测复杂度，减少终端设备的搜索计算时间、功率消耗和时延。
另外，本发明实施例的技术方案，通过同步信号块的传输方式向接收侧指示该同步信号块是否关联控制信息，可以使得接收侧的终端设备通过检测该同步信号块的传输方式，即可确定该同步信号块是否关联了控制信息，不需要再盲检物理广播信道，从而能够降低终端设备的检测复杂度，减少终端设备的功率消耗和时延。
应理解，本发明实施例的各种实施方式既可以单独实施，也可以结合实施，本发明实施例对此并不限定。
例如，本发明实施例中向接收侧指示关联控制信息的同步信号块的资源位置的实施方式与通过同步信号块的传输方式向接收侧指示该同步信号块是否关联控制信息的实施方式分别可以单独实施，也可以结合实施。下面单独描述通过同步信号块的传输方式向接收侧指示该同步信号块是否关联控制信息的实施方式。应理解，除以下描述外，下述实施例还可以参考前述各实施例中的相关描述，以下为了简洁，不再赘述。

本申请中，名词“网络”和“系统”可能会交替使用，但本领域的技术人员可以理解其含义。另外，本文中的部分英文简称是以LTE系统为例对本申请实施例进行的描述，其可能随着网络的演进发生变化，具体演进可以参考相应标准中的描述。
接下来，请参照图18，为本申请一个实施例中寻呼消息的传输方法的流程示意图。该方法通过网络设备与终端设备之间的交互实现，其中，该网络设备可以是蜂窝网络下的基站，也可以是WIFI中的无线接入点。
1801：网络设备配置传输寻呼消息的频域资源；
1802：网络设备向终端设备发送寻呼指示信息，所述寻呼指示信息用于指示所述传输寻呼消息的频域资源。
1803：终端设备接收所述寻呼指示信息，并根据所述寻呼指示信息获得寻呼消息。
以下，对1801进行更为详细地说明。
其中，用于传输寻呼消息的频域资源可以为部分带宽(bandwidth，BWP)。通常情况下，一个BWP对应一个终端设备，在初始接入的时候终端设备会被分配默认的BWP的带宽或者子带。在不同的实施方式中，BWP可以由一组连续的物理资源块(Physical Resource Block，PRB)组成，或者BWP可以为一个单带宽载波(single wideband carrier)中的一个子带，或者BWP还可以是载波聚合(carrier aggregation，CA)中的一个CC带宽。
再然后，对1802进行更为详细地说明。
在一个实施方式中，上述寻呼指示信息可以为寻呼参考标识。可以理解的是，不管是寻呼指示信息还是寻呼参考标识，其作用在于指示寻呼消息的存在或者指示寻呼消息的位置，上述命名只是示例性地描述，而并非用于对该信息的限定。在下文中，将以寻呼参考标识为例进行说明。
在不同的实施方式中，网络设备可以将寻呼参考标识承载在不同的信令中来进行发送，以下将针对不同的信令进行示例性地说明：
(1)网络设备将寻呼参考标识承载在同步信号块(synchronization signal block，SSB)中发送。具体地，该寻呼参考标识承载在SSB的物理广播信道(physical broadcast channel，PBCH)中。在一种可能的实施方式中，承载在PBCH中的寻呼参考标识用于指示是否存在关联的寻呼消息，终端设备在搜索到SSB时，可以根据其中的寻呼参考标识确定搜索到的SSB是否存在关联的寻呼消息。在另一种可能的实施方式中，承载在PBCH的寻呼指示信息用于指示关联的寻呼消息的位置，终端在搜索到SSB时，可以根据其中的寻呼指示信息到相应地位置接收寻呼消息。；或者，
(2)上述寻呼参考标识还可以为PBCH中的驻留(camp on available)标识位，即网络设备复用PBCH中的camp on available标识位来指示与SSB关联的寻呼消息。从而，当终端设备接收到SSB时，根据其中PBCH的camp on available标识位来指示是否存在与SSB关联的寻呼消息；或者，
(3)上述寻呼参考标识还可以承载在剩余系统信息(remaining system information，RMSI)中发送。从而，终端设备可以根据搜索到的RMSI中的寻呼参考标识来判断搜索到的RMSI中是否有关联的寻呼消息；或者，
(4)若RMSI和寻呼消息是对应时，即当一个SSB有关联的RMSI则表示该SSB也关联有寻呼消息，当一个SSB没有关联的RMSI则表示该SSB没有关联的寻呼消息。此时，上述寻呼参考标识可以为PBCH中的RMSI存在标识(RMSI presence flag)，即网络设备复用PBCH中的RMSI存在标识来指示是否有与SSB关联的寻呼消息。其中，RMSI存在标识用于指示SSB是否有关联的RMSI。从而，终端设备可以根据搜索到的SSB中PBCH的RMSI存在标识，来判断搜索到的SSB是否有关联的寻呼消息。
示例性地，上述寻呼参考标识可以采用“0”和“1”，来标识是否存在关联的寻呼消息。网络设备可以采用“0”来表示存在关联的寻呼消息，采用“1”来表示不存在关联的寻呼消息；或者，网络设备可以采用“1”来表示存在关联的寻呼消息，采用“0”来表示不存在关联的寻呼消息。
在一个实施例中，网络设备会在默认的BWP上发送寻呼消息，即当终端设备根据寻呼参考标识确定存在寻呼消息时，可以到默认的BWP上去搜索或者接收寻呼消息。该默认的BWP可以为承载SSB的BWP，或者该默认的BWP可以为承载RMSI的BWP。
在另一个实施例中，网络设备会指示承载寻呼消息的BWP，即当终端设备根据寻呼参考标识确定存在寻呼消息时，可以到指示的BWP上去搜索或者接收寻呼消息。示例性地，承载寻呼消息的BWP可以是承载寻呼消息的下行共享物理信道(physical downlink shared channel，PDSCH)的BWP，或者可以是承载调度所述寻呼消息的物理下行控制信道(physical downlink control channel，PDCCH)的CORESET的BWP，或者还可以是同时承载寻呼消息的PDSCH和调度所述寻呼消息的PDCCH的CORSET的BWP。网络设备可以通过寻呼参考标识来指示BWP，或者网络设备可以向终端设备发送指示位置的信息，以使终端设备可以在指示的BWP上搜索寻呼消息。具体地指示方法将在下文进行描述。
在一个实施方式中，网络设备可以在系统带宽内发送多个SSB和多个RMSI，且配置在一个BWP上发送寻呼消息。请参照图19，网络设备配置了3个SSB(SSB1、SSB2以及SSB3)，每一SSB所占用的带宽为终端设备支持的最小系统带宽。每一SSB具有关联的RMSI(associated RMSI)，网络设备在BWP1上发送SSB1及其关联的RMSI1，在BWP2上发送SSB2及其关联的RMSI2，在BWP3上发送SSB3及其关联的RMSI3，并配置在BWP2上传输寻呼消息。当终端搜索到SSB1时，根据SSB1中指示的RMSI指示信息获得承载SSB1关联的RMSI1的BWP1，查找到RMSI1并根据RMSI1指示的寻呼指示信息找到承载寻呼消息的BWP2，从而可以在该BWP2上读取寻呼消息。类似地，终端设备可以根据SSB2、SSB3相应地RMSI找到承载寻呼消息的BWP2。
网络设备还同时向终端设备发送寻呼，终端设备可以根据频率偏移信息获取用于传 输寻呼消息的BWP。具体地，SSB以及RMSI分别包含频率偏移信息，其中，SSB中的频率偏移信息用于指示承载RMSI的BWP相对于SSB所在BWP的偏移量，RMSI中的频率偏移信息用于指示承载寻呼信息的BWP相对于承载RMSI的BWP的偏移量。从而，当搜索到SSB时，终端设备可以根据搜索到的SSB中指示的频率偏移信息来寻找该SSB对应的承载RMSI的BWP，再根据RMSI中指示的用于发送Paging的BWP相对RMSI的BWP的频率偏移信息来找到承载寻呼消息(paging)的BWP，从而可以在该BWP上读取寻呼消息。该频率偏移信息将在下文进行示例性地描述。
可以理解的是，在不同的实施方式中，上述用户发送寻呼消息的BWP可以和承载RMSI的BWP的中心频点可以相同，也可以不同。
在另一个实施例中，网络设备的系统带宽内通过配置一个RMSI，且在一个BWP上发送寻呼消息。当网络设备配置多个同步信号块且配置一个RMSI时，所述寻呼指示信息承载在所述一个RMSI中发送；其中，每一所述同步信号块中包括RMSI指示信息，所述RMSI指示信息用于向终端设备指示所述一个RMSI的位置。请参照图20，网络设备配置了3个SSB(SSB1、SSB2以及SSB3)，每一SSB所占用的带宽为终端设备支持的最小系统带宽。其中，该一个RMSI与SSB2关联。网络设备可以配置在任意一个BWP上传输RMSI，在本实施例中，网络设备在BWP2上传输RMSI，可以理解的是，在其它的实施例中，网络设备也可以配置在BWP1或者BWP3上传输RMSI，在其他实施方式中，网络设备也可以在其他的BWP上传输RMSI，本申请对此不作限定。另外，虽然在图20中，用于发送寻呼信息的BWP的中心频点可以和承载RMSI的BWP的中心频点相同，可以理解地是，用于发送寻呼信息的BWP的中心频点可以和承载RMSI的BWP的中心频点也可以不同。
每个SSB的PBCH中携带指示该一个的RMSI位置的RMSI指示信息，以指示该一个RMSI。终端在搜索到SSB时，根据SSB中指示的RMSI指示信息来获得承载关联的RMSI的BWP，再根据RMSI中所指示的寻呼消息指示信息获取到承载寻呼消息的BWP。可选地，当SSB中的PBCH携带寻呼信息指示信息时，终端可以根据寻呼信息指示信息获得承载寻呼消息的BWP。
通过在SSB中指示RMSI的频率信息，当终端搜索到一个SSB后，可以根据该SSB所指示的RMSI的RMSI指示信息可以找到RMSI，而不需要重新搜索SSB以及进行SSB同步操作，从而降低了复杂度。
在又一个实施例中，当网络设备配置多个同步信号块且配置一个RMSI时，其中一个SSB具有关联的RMSI(以下简称：第一SSB)时。寻呼指示信息承载在所述一个RMSI中发送；其中，所述多个同步信号块中包括一个与所述第一RMSI关联的第一同步信号块，所述第一同步信号块中包括RMSI指示信息，所述RMSI指示信息用于向终端设备指示所述RMSI的位置；所述多个同步信号块中除第一同步信号块以外的为第二同步信号块，所述第二同步信号块中包括所述第一同步信号块指示信息，所述第一同步信号块指示信息用于指示所述第一同步信号块与所述第二同步信号块的相对位置。当网络设备配置了多个SSB，除第一SSB以外的其它的第二SSB需要携带第一同步信号块指示信息，该第一同步信号块指示信息用于指示与第一SSB的频率偏移，以使其它的SSB可以获取第一SSB的位置。以图21中的SSB1、SSB2以及SSB3为例，假设SSB2 为第一SSB，即SSB2具备关联的RMSI，则SSB1及SSB3分别携带SSB2的SSB指示信息。从而，当终端设备搜索到SSB1时，可以根据其中所携带的SSB指示信息获取到SSB2，并进一步根据SSB2关联的RMSI获得寻呼消息的位置，从而在相应的位置搜索或者接收寻呼消息。终端设备在接收到SSB3时，也采用类似地操作。
通过在不具备RMSI指示信息的SSB中指示具备RMSI指示信息的SSB的位置偏移，当UE搜索到一个SSB后，可以根据该SSB中的位置偏移信息找到承载有的RMSI指示信息的SSB的BWP，进而找到用于发送寻呼消息的BWP的位置，节省终端设备盲检SSB的次数，降低了终端设备复杂度。
应理解，本实施例并不限定与承载RMSI的BWP和承载默认的SSB的BWP相同的场景，即当承载RMSI的BWP不同于各个承载SSB的BWP时，仍然可以由网络设备配置某个SSB作为默认的SSB，从而采用本实施例的方式来实施。
在又一个实施例中，网络设备配置在多个BWP上发送寻呼消息，且在多个配置的BWP上发送的寻呼消息不重复。终端根据RMSI中的寻呼配置信息获得其所被调度的用于发送寻呼信息的BWP，其中，寻呼配置信息中包括：本载波中被激活的用于发送寻呼消息的BWP的个数Nn,用于发送寻呼消息的BWP编号(paging channel index，PCHI)和/或寻呼指示信息。
具体地，用于发送寻呼消息的PCHI符合以下公式：
Figure PCTCN2018109189-appb-000001
其中
Figure PCTCN2018109189-appb-000002
N＝min(T,nB)，nB、T为非连续接收(discontinuous reception，DRX)参数，具体地，T为DRX周期(cycle)，处于待机(idle)状态的UE每隔T被唤醒来收听寻呼消息，nB表示每个DRX cycle里有多少个寻呼时机(Paging Occasion，PO)，一个PO表示一次寻呼消息的发送。UE_ID可以是以下多个标识中的任意一个标识的值对一固定数值取余后的数值：国际移动用户标识(international mobile subscriber identity，IMSI)、国际移动设备标志(international mobile equipment identity，IMEI)、临时移动用户标志(temporary mobile subscriber identity，TMSI)、无线网络临时标识(radio network temporary identifier，RNTI)、国际移动用户标志(international mobile subscriber identity，IMSI)、国际移动设备标志(international mobile equipment identity，IMEI)、临时移动用户标志(temporary mobile subscriber identity，TMSI)、无线网络临时标识(radio network temporary identifier，RNTI)。系统根据分组的终端在其对应的BWP上发送paging消息。
示例性地，终端设备根据RMSI中的寻呼消息配置信息和UE_ID计算得到所被调度的用于发送寻呼消息的BWP的编号，从而获得用于承载寻呼消息的BWP的频率位置。 以UE_ID＝722的终端设备1，以及UE_ID＝739的终端设备2为例，T＝32，nB＝T/2＝16，N＝min(T,nB)＝16，Ns＝max(1,nB/T)＝1，获得终端设备1的PCHI＝FLOOR(722/16)MOD3＝0，终端设备2在PCHI对应的BWP上搜索或接收寻呼消息，获得终端设备2的PCHI＝FLOOR(739/16)MOD 3＝1，终端设备2在PCHI对应的BWP上搜索或接收寻呼消息。
网络设备在一个宽带载波中配置多个BWP用于发送寻呼消息消息,网络设备将用户进行分组，不同的用户分组对应不同的BWP，寻呼消息在这些BWP上不重复，从而节省寻呼资源。
上述方案既可以应用于授权(licensed)频段，亦可以应用于非授权(unlicensed)频段，对此本申请不作限定。但由于非授权频段的应用场景下，存在多个不同通信系统的竞争机制，以下，将针对非授权频段进行进一步地描述。
在unlicensed频段中，为了保证公平性，网络设备或者终端设备在发送数据之前需要进行先听后说(listen before talk，LBT)操作。
在非授权频段的应用场景下，以寻呼消息承载在寻呼帧(paging frame，PF)上为例进行说明，该寻呼帧也可以称为寻呼消息帧。RMSI中还可以携带以下寻呼帧参数中的一个或多个：第一时间偏移值、第二时间间隔以及寻呼帧的长度(paging of window，POW)。第一时间偏移值为寻呼帧相对于无线帧(radio frame，RF)起始时刻的偏移值，第一时间偏移值可以是以符号为单位，也可以是以时隙(slot)或者微时隙(mini slot)为单位。第一时间偏移值的值可以为零，此时意味着对应的寻呼帧与无线帧的起始时刻对齐。示例性地，当所述网络设备配置在多个BWP上发送寻呼消息时，各个BWP具有不同的第一时间偏移值P0、P1、P2。第二时间间隔为若在对应的BWP上未侦听到寻呼消息时，连续侦听寻呼消息的最长时间间隔。第二时间间隔可以是以符号为单位，也可以是以时隙(slot)或者微时隙(mini slot)为单位。
当网络设备针对每一SSB配置RMSI时，每一RMSI携带对应的SSB所在BWP上传输的寻呼帧参数。当网络设备针对多个SSB仅配置一个RMSI时，该一个RMSI携带对应的多个SSB分别所在BWP上传输的寻呼帧参数，即携带多个寻呼帧参数。
以下，请参照图22，以一个RMSI对应多个SSB为例进行说明。网络设备配置了三个SSB，分别为SSB1、SSB2以及SSB3，每一SSB所占用的带宽为终端设备所支持的最小带宽。该三个SSB分别在多个BWP(BWP1、BWP2以及BWP3)上传输，该多个BWP还传输寻呼消息。此时，该一个RMSI携带分别在BWP1、BWP2以及BWP3上传输的寻呼帧参数。POW1表示paging fram1的寻呼帧长，paging fram2、3类似。
如图所示，paging frame 1的第一时间偏移值为P0，即相对无线帧的起始时刻的偏移值为P0；paging frame 2的第一时间偏移值为P1，即相对无线帧的起始时刻的偏移值为P1；paging frame 3的第一时间偏移值为P2，即相对无线帧的起始时刻的偏移值为P2。其中，P0<P1<P2。
根据接收到的RMSI，终端设备在BWP1上侦听寻呼消息，若在第二时间间隔(例如：P1与P2之间的差值)内未侦听到寻呼消息，则跳转到BWP2上侦听寻呼消息；若在第二时间间隔侦听到寻呼消息，但侦听到的寻呼消息中没有查找到自己的寻呼消息时，即寻呼消息列表中没有包含该终端设备的UE_ID，则继续侦听直到POW1结束；若在第二时间间隔侦听到寻呼消息，且查找到自己的寻呼消息，则接收寻呼消息。
通过配置在多个BWP上发送且相对于无线帧偏移时长不同的寻呼消息帧，可以避免由于LBT结果的不确定性，有可能部分未侦听成功的BWP上不能发送寻呼消息，则在该BWP上驻留的终端设备无法接收到寻呼消息。从而，可以提高在unlicensed频段中终端设备侦听到寻呼消息的概率，从而提高通讯效率。
示例性地，上述各个实施例中寻呼指示信息、RMSI指示信息以及SSB指示信息可以包含或者采用频率偏移的方式来指示，以下针对频率偏移的坑情况进行示例性地说明。所述频率偏移信息用于指示BWP的频率位置信息。
当网络设备与终端均存在默认带宽时，上述频率偏移信息可以是：(1)寻呼信息所在的BWP的预定频点相对于承载SSB的BWP的起始频点或者承载RMSI的BWP的起始频点的偏移量；或者(2)承载寻呼信息的BWP的预定频点相对于承载SSB的BWP的结束频点或者RMSI所在的BWP的结束频点的偏移量；或者(3)承载寻呼信息的BWP的预定频点相对于承载SSB的BWP的中心频点或者承载RMSI的BWP的中心频点的偏移量。其中，承载寻呼信息的BWP的预定频点可以为起始频点、结束频点或者中心频点。
当网络设备与终端不存在默认带宽时，上述频率偏移信息可以为：(1)承载寻呼信息的BWP的起始频点和结束频点相对承载SSB的BWP的起始频点或者承载RMSI的BWP的起始频点的偏移量；或者(2)承载寻呼信息的BWP的起始频点和结束频点相对承载SSB的BWP的结束频点或者承载RMSI的BWP的结束频点的偏移量；或者(3)承载寻呼信息的BWP的起始频点和结束频点相对承载SSB的BWP的中心频点或者承载RMSI的BWP的中心点的偏移量。
当所述频率偏移信息若不存在默认带宽大小约定的前提下，该频率偏移信息也可以是被指示的BWP的起始频点或结束频点或中心频点相对承载SSB的BWP或承载RMSI的BWP的起始频点的偏移量和带宽大小；
可选的，该频率偏移信息可以是被指示的BWP的起始频点或结束频点或中心频点相对承载SSB的BWP或承载RMSI的BWP的结束频点的偏移量和带宽大小；
进一步可选的，该频率偏移信息可以是被指示的BWP的起始频点或结束频点或中心频点相对承载SSB的BWP或承载RMSI的BWP的中心频点的偏移量和带宽大小；
上述频点和带宽的单位可以是以Hz，KHz，或MHz等。上述偏移量的指示粒度可以是载波间隔、RB、或者RB组(RB group，例如10个RB)来进行。
