 本发明的最佳实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
应理解，本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯（Global System of Mobile communication， GSM）系统、码分多址（Code Division Multiple Access，CDMA）系统、宽带码分多址（Wideband Code Division Multiple Access，WCDMA）系统、通用分组无线业务（General Packet Radio Service，GPRS）、长期演进（Long Term Evolution，LTE）系统、LTE频分双工（Frequency Division Duplex，FDD）系统、LTE时分双工（Time Division Duplex，TDD）、通用移动通信系统（Universal Mobile Telecommunication System，UMTS）、全球互联微波接入（Worldwide Interoperability for Microwave Access，WiMAX）通信系统、新无线(New Radio，NR)或未来的5G系统等。
特别地，本申请实施例的技术方案可以应用于各种基于非正交多址接入技术的通信系统，例如稀疏码多址接入（Sparse Code Multiple Access，SCMA）系统、低密度签名（Low Density Signature，LDS）系统等，当然SCMA系统和LDS系统在通信领域也可以被称为其他名称；进一步地，本申请实施例的技术方案可以应用于采用非正交多址接入技术的多载波传输系统，例如采用非正交多址接入技术正交频分复用（Orthogonal Frequency Division Multiplexing，OFDM）、滤波器组多载波（Filter Bank Multi-Carrier，FBMC）、通用频分复用（Generalized Frequency Division Multiplexing，GFDM）、滤波正交频分复用（Filtered-OFDM，F-OFDM）系统等。
本申请实施例中的终端设备可以指用户设备（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用陆地移动通信网络（Public Land Mobile Network，PLMN）中的终端设备等，本申请实施例并不限定。
本申请实施例中的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GSM或CDMA中的基站（Base Transceiver Station，BTS），也可以是WCDMA系统中的基站（NodeB，NB），还可以是LTE系统中的演进型基站（Evolutional NodeB，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，本申请实施例并不限定。
图1是本申请实施例一个应用场景的示意图。图1中的通信系统可以包括终端设备10和网络设备20。网络设备20用于为终端设备10提供通信服务并接入核心网，终端设备10通过搜索网络设备20发送的同步信号、广播信号等而接入网络，从而进行与网络的通信。图1中所示出的箭头可以表示通过终端设备10与网络设备20之间的蜂窝链路进行的上/下行传输。
在LTE系统中，当终端设备初始接入或者需要测量邻小区时，均需要进行小区搜索过程，终端设备进行小区搜索的目的是为了获取小区物理ID，并且同时得到系统的定时同步和频率同步信息，这个过程是与系统带宽无关的，终端设备可以直接检测和获取。物理层是通过物理小区ID（Physical Cell Identities，PCI）来区分不同的小区的。物理小区ID总共有504个，它们被分成168个不同的组（记为N(1)_ID，范围是0-167），每个组又包括3个不同的组内标识（记为N(2)_ID，范围是0-2）。因此，物理小区ID（记为Ncell_ID）可以通过下面的公式计算得到：
PSS就是用来传输组内ID即N(2)_ID值，而SSS是用来传输组ID即N(1)_ID值。对于FDD制式，PSS周期的出现在时隙0和时隙10的最后一个OFDM符号上，SSS周期的出现在时隙0和时隙10的倒数第二个符号上。对于TDD制式，PSS周期的出现在子帧1、6的第三个OFDM符号上，SSS周期的出现在子帧0、5的最后一个符号上。
在NR通信系统中，引进了多天线阵列、波束赋形等设计，比如把原来的一个小区用多个波束来覆盖，波束增益可以在一定程度上弥补使用高频段所带来的覆盖减小，同时还可以减低相互间的干扰，增强系统性能。
NR中引入了同步信号块SS Block，主要由PSS和SSS组成，在某些SS Block中还可以包括PBCH，甚至有可能包括第三类同步信号，本申请实施例对SS block包括的信号类型不作限定。在NR中，同步信号的长度也可以增加，例如可以变为127；同时也可能在频域上重复，使得同步带宽整数倍增加。同步信号以SS Block为最小单元，多个SS Block组成一个SS burst，多个SS burst组成一个SS burst set，在SS Block内还可能以时分复用(Time Division Multiple，TDM)形式映射。如下图2所示，同步信号周期也即SS burst周期为10ms，这里的SS burst周期可以认为是同一个小区内相同同步信号块传输的周期，可以采用3个波束发送SS Block#1，SS Block#2，SS Block#3，其中每个SS Block可以如图2所示没有间隔，也可以是相隔一定单位的时域单元。在一个SS burst周期内，不同SS Block之间的时序图还可以是如图3所示的信号交叉的情况。
图4示出了本申请实施例的传输信号的方法100的示意性框图。如图4所示，该方法100可以由终端设备执行，具体地可以由用户设备执行，该方法100包括：
S110，确定多个同步信号块中每个同步信号块在第一周期内的时序；
S120，根据该每个同步信号块在该第一周期内的时序，分别接收该多个同步信号块。
首先，需要说明的是，这里所谓同步信号块的时序是指同步信号块所占的时域资源，可以是以时域单元为单位。例如，第一周期的资源在时域上包括7个OFDM符号，假如网络设备向终端设备发送3个同步信号块，并且网络设备通过一定方式告诉终端设备这3个同步信号块在第一周期的哪几个OFDM符号上，这样终端设备就可以直接在网络设备告诉的OFDM符号上接收这3个同步信号块。
可选地，该第一周期的时间长度可以等于该多个同步信号块的传输周期。
应理解，本申请实施例中的周期的长度可以与现有技术中的同步信号的周期类似，可以是同一小区任一SS Block的传输周期，还可以是同一小区传输SS Block的同一波束的传输周期。具体的可以如图2或图3所示的周期10ms。其中，相同SS Block是指包括的信号类型完全一样，并且包括的信号的内容也是完全相同的。若两个SS Block包括的信号类型不同或者包括的信号类型虽相同但信号的内容不完全相同，或者两个SS Block采用的波束不同，那么这两个SS Block是不同的。例如，SS Block#1包括PSS和SSS，PSS传输的N(2)_ID为0，SSS传输的N(2)_ID为10，采用的波束为波束1；而SS Block#2也包括PSS和SSS，但PSS传输的N(2)_ID为0，SSS传输的N(2)_ID为10，而采用的波束为波束2或者SS Block#2包括PSS、SSS还有PBCH，那么SS Block#1和SS Block#2是不同的。
还应理解，终端设备还可以确定在一个周期内的某一块时域资源是用来接收多个SS Block，那么终端设备就可以只在那一部分时域资源上检测该多个SS Block即可。例如，若网络设备在一个周期内向终端设备发送5个SS Block，那么终端设备可以确定在一个周期内的第2个时域单元至第6个时域单元上接收SS Block，但有可能只在第2个时域单元至第4个时域单元上就检测到该5个SS Block。也就是说，终端设备根本不需确定每一个SS Block在哪些具体的资源上传输，只需要知道大概的位置即可。
因此，本申请实施例的传输信号的方法，终端设备通过提前确定多个SS Block在一个周期中的时序，就可以在固定的时域资源上接收SS Block，从而使得终端设备可以大大降低计算复杂度，减少检测时间，节约功耗。
可选地，在本申请实施例中，该方法还包括：接收网络设备发送的指示信息，该指示信息用于指示待发送的多个同步信号块的数目，该确定多个同步信号块中每个同步信号块在第一周期内的时序，包括：根据该多个同步信号块的数目，确定与该多个同步信号块的数目对应的该每个同步信号块在该第一周期内的时序。
进一步地，网络设备为终端设备配置多种对应关系，并且发送给终端设备。网络设备向终端设备指示信息，该指示信息用于指示待发送的多个同步信号块的数目，终端设备在根据指示信息指示的数目在多种对应关系中确定第一对应关系，并根据该第一对应关系确定该每个同步信号块在第一周期内的时序。
具体地，网络设备可以提前配置好向终端设备发送的SS Block的数目与这些SS Block在一个SS burst周期内的时序关系。例如，网络设备可以配置3个SS Block分别在一个SS burst周期的前3个时域单元上传输；或者网络设备可以配置5个SS Block分别在一个SS burst周期的1、3、5、7、9的时域单元上传输等。或者网络设备还可以同时配置3个SS Block的时序和5个SS Block的时序。总之，这种指示方式下，SS Block的时序通常是通过静态配置或半静态配置的。
可选地，在本申请实施例中，该方法还包括：接收网络设备发送的第一同步信号块，该第一同步信号块与该多个同步信号块中任一同步信号块在该第一周期内的时序不同；接收网络设备发送的指示信息，该指示信息用于指示该任一同步信号块与该第一同步信号块之间间隔的时域单位数目；该确定多个同步信号块中每个同步信号块在第一周期内的时序，包括：根据该第一同步信号块在该第一周期内的时序和该时域单位数目，确定该每个同步信号块在该第一周期内的时序。
可选地，网络设备还可以提前向终端设备发送指示信息，指示信息用于指示多个同步信号块相邻两个之间相隔的时域单位数目，若终端设备检测出来其中一个同步信号块的时序，那么终端设备可以根据该指示信息指示的多个同步信号块中相邻两个之间相隔的时域单位数目，确定出来其他同步信号块可能的时序。
进一步地，若任意两个同步信号块之间相隔的时域单位数目相同，那么网络设备可以只向终端设备发送的指示信息可以只指示一个间隔数，若网络设备还告诉终端设备待发送的同步信号块的数目，那么终端设备可以确定出网络设备将发送的同步信号块可能的时序。无论任意两个同步信号块之间相隔的时域单位数是否相同，网络设备向终端设备发送的指示信息都可以指示多个间隔，那么网络设备不需要告诉终端设备待发送的同步信号块的数目，终端设备即可确定出来网络设备将发送的同步信号块可能的时序。
例如，网络设备要向终端设备发送5个SS Block，并且网络设备分别准备在一个SS burst周期内的第1、3、5、7和9个时域单元上传输，那么网络设备可以告诉终端设备每两个SS Block之间相隔一个时域单元，当终端设备检测到其中一个如第3个时域单元上的SS Block之后，那么终端设备就可以依次在该SS burst周期内的其他单数时域单元上依次去检测SS Block，网络设备在告诉终端设备相邻两个SS Block之间是等间隔的，以及间隔的时域单元数目的同时，也可以告诉终端设备总共有多少个SS Block。又例如，任意两个SS Block之间间隔的时域单元数目也可以不相等，那么网络设备可以告诉终端设备(K-1)个间隔数目，其中K为SS Block的数目，当终端设备检测到其中一个SS Block之后，即可以根据该(K-1)个间隔数目确定出其他SS Block在一个SS burst周期的时域资源位置。或者，网络设备还可以告诉终端设备第一个SS Block在一个SS burst周期内的时域资源位置，那么终端设备可以直接根据该多个SS block中每两个SS Block之间的间隔以及第一个SS Block的位置，就可以确定出来其他SS Block的位置。
可选地，在本申请实施例中，该方法还包括：接收网络设备发送的指示信息，该指示信息用于指示该每个同步信号块在该第一周期内的时序；该确定多个同步信号块中每个同步信号块在第一周期内的时序，包括：根据该指示信息，确定该每个同步信号块在该第一周期内的时序。
具体地，网络设备还可以动态的向终端设备指示将要向终端设备发送的多个SS Block中每个SS Block在一个SS burst周期中的具体位置。例如，网络设备可以直接向终端设备指示将要发送的3个SS Block分别被配置于一个SS Burst周期的前3个时域单元上。那么终端设备在接收到该指示信息后，可以直接在该SS Burst周期的前3个时域单元上检测该三个SS Block。
可选地，在本申请实施例中，该方法还包括：接收网络设备发送的指示信息，该指示信息用于指示多个对应关系中的第一对应关系，该对应关系为该每个同步信号块在该第一周期内时序的映射；该确定多个同步信号块中每个同步信号块在第一周期内的时序，包括：根据该第一对应关系，确定该每个同步信号块在该第一周期内的时序。
具体地，网络设备可以将该多个SS Block在一个SS burst周期内的时域位置提前固定好，并且可以提前配置多种对应关系。举例来说，网络设备提前配置好向终端设备发送5个SS Block，并且将用于发送该5个SS Block的时域资源在一个SS burst周期中固定。例如，可以将该5个SS Block固定在一个SS burst周期中的前5个时域单元上；网络设备还可以将该5个SS Block固定在一个SS burst周期中的第2、3、5、7、8个时域单元上。网络设备可以保存这两种配置关系，并将该两种配置关系发送给终端设备，在网络设备准备向终端设备发送5个SS Block时，可以先向终端设备发送一个指示信息，指示其中一种配置关系，这样终端设备在接收到该指示信息之后，即可以知道是哪一种配置关系，就采用指示信息指示的配置关系去接收网络设备发送的SS Block。例如，可以采用一个bit的指示信息来指示配置关系，可以用0来表示上述第一种配置关系，1表示上述第二种配置关系。
应理解，上述各种指示方式只是示意性说明，网络设备还可以采用上述各种指示方式的组合还实现终端设备确定多个SS Block在一个SS burst周期内的时域位置。
可选地，在本申请实施例中，该指示信息可以承载于广播消息、系统消息、无线资源控制(Radio Resource Control，RRC)信令、MAC CE信令和DCI信令中的至少一种。
具体地，在终端设备未与网络设备建立网络连接的情况下，可以通过小区的广播消息或者系统消息发送上述各种指示信息；而在终端设备与网络设备建立RRC连接之后，根据规定或者需求，网络设备可以通过RRC信令、MAC CE信令或者DCI信令发送上述各种指示信息。SS Block在一个SS burst周期中的时域位置可以是协议规定好的，也可以是网络设备通过静态或半静态方式配置好的。
可选地，在本申请实施例中，接收网络设备发送的指示信息，包括：在主载波上接收该网络设备发送的该指示信息。
LTE系统或者NR系统中的载波都可以作为主载波，可以通过主载波通知终端设备其辅载波中SS Block在一个周期内的时序，换句话说，可以在主载波上通过上述各种信令向终端设备发送指示信息。
需要说明的是，网络设备向终端设备发送的多个SS Block可以是网络设备配置的一个小区内的全部SS Block数目，也可以是部分SS Block数目，在本申请实施例中，对终端设备来讲，与小区配置的SS Block数目无关，只关注网络设备发送的SS Block数目。网络设备向终端设备发送的多个SS Block还可以包括终端设备所在小区的邻小区的部分或全部SS Block。
可选地，在本申请实施例中，不同SS Block可以采用不同波束传输，网络设备可以向终端设备发送系统消息或者广播消息采用的波束周围的波束对应的SS Block，例如，图2中的SS Block#1采用波束1，SS Block#2采用波束2，SS Block#3采用波束3，若网络设备采用波束2在图2中的SS Block#2的时域位置上发送广播消息或系统消息，那么网络设备可以通知终端设备SS Block#3的时域位置，那么终端设备可以直接在指示的时域位置上接收SS Block。
还应理解，上述网络设备提前配置的各种SS Block的时域位置可以是网络设备配置的小区内的最大SS Block数目的每个SS Block的时域位置。若网络设备向终端设备发送的是部分SS Block数目，那么终端设备依然在上述配置的时域位置去检测。例如，小区内最大SS Block数目为4，并且网络设备配置4个SS Block中的每个SS Block分别对应一个SS burst周期内的前4个时域单元中的每个时域单元。若网络设备向终端设备发送3个SS Block，终端设备依旧在前4个时域单元上检测，终端设备可能在前3个时域单元是检测到3个SS Block，在最后一个时域单元上并没有检测到。或者也可以是在后3个时域单元上检测到，在第一个时域单元上没有检测到。本申请实施例并不限于此。
还应理解，在本申请实施例中的时域单元可以是OFDM符号，也可以是时隙、微时隙等。
图5示出了本申请实施例的传输信号的方法200的示意性框图。如图5所示，该方法200可以由网络设备执行，具体地可以由基站执行，该方法200包括：
S210，向终端设备发送指示信息，该指示信息用于该终端设备确定多个同步信号块中每个同步信号块在第一周期内的时序；
S220，根据该每个同步信号块在该第一周期内的时序，向该终端设备发送该多个同步信号块。
因此，本申请实施例的传输信号的方法，通过向终端设备指示多个SS Block在一个SS burst周期内的时序，从而使得终端设备可以大大降低计算复杂度，减少检测时间，节约功耗。
可选地，在本申请实施例中，该多个同步信号块为同一小区的不同同步信号块，该第一周期的时间长度等于该多个同步信号块的传输周期。
