Description

同步信号块指示及确定方法、网络设备和终端设备
本申请要求于2017年08月11日提交中国专利局、申请号为201710687868.7、申请名称为“同步信号块指示及确定方法、网络设备和终端设备”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
本发明涉及通信技术领域，尤其涉及一种同步信号块指示及确定方法、网络设备和终端设备。
背景技术
同步信号块是新无线(New Radio，NR)中定义的一种信号结构，其包含主同步信号(Primary Synchronization Sigal，PSS)、辅同步信号(Secondary Synchronization Signal，SSS)以及物理广播信道(Physical Broadcast Channel，PBCH)。PSS和SSS主要作用是帮助用户设备(User Equipment,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。
为了支持NR的多波束特性，NR定义了同步信号突发集(Synchronization Signal Burst Set，SS burst set)。同步信号突发集包含了一个或者多个同步信号块，在不同的频率范围，同步信号突发集所能包含的同步信号块的最大数量L是不同的。具体地，当频率不超过3GHz时，L＝4；当频率在3GHz和6GHz之间时，L＝8；当频率在6GHz和52.6GHz之间时，L＝64。
在实际传输过程中，一个同步信号突发集中实际传输的同步信号块的数目并不总是等于L，也可能会小于L，基站可以在没有传输同步信号块的时隙发送其他信息或者调度UE进行传输。这样一来，基站就需要将实际传输的同步信号块通知给UE，以便UE成功接收同步信号块。

本说明书结合终端设备描述了各个实施例。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，以及只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。
本说明书结合网络设备描述了各个实施例。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)。
本申请文件举例但不作为限定的网络设备中，一个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。

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。
在本发明实施例中，同步信号块(Synchronization Signal block，SS block，SSB)是NR无线网络中定义的一种信号结构，下面将结合图2对同步信号块进行简要说明。
如图2所示，每一个同步信号块由一个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号的主同步信号(Primary Synchronization Signal，PSS)，一个符号的辅同步信号(Secondary Synchronization Signal，SSS)，和两个符号的物理广播信道(Physical Broadcast Channel，PBCH)组成。PSS、SSS和PBCH在同步信号块中的位置如图2所示，其中，PSS/SSS的序列长度为127，在频域上占有127个子载波(Subcarrier，SC)，而PBCH在频域上占有288个子载波。
应理解，在本发明各种实施例中，符号和子载波分别表示传输信号的时频资源在时域和频域的粒度单元，它们可以具有目前通信系统中的含义，也可以具有未来通信系统中的含义。另外，若在未来通信系统中它们的名称发生了改变，它们也可以变换为未来通信系统中的名称。
在本发明各种实施例中，同步信号块组也可以称为同步信号阵(Synchronization Signal Burst，SS burst)，若在未来通信系统中同步信号块组的名称发生了改变，它们也可以变换为未来通信系统中的名称。
在本发明各种实施例中，网络设备在同步信号的一个传输周期内可以发送的同步信号块的最大数量为一个确定的值，即同步信号突发集中包含的同步信号块的最大数量是确定的，为了简洁，将同步信号突发集中包含的同步信号块的最大数量记为L。例如当频率在6GHz和52.6GHz之间时，L＝64。在实际通信过程中，网络设备实际发送的同步信号块的数量可以小于最大数量，例如小于64，网络设备可以利用未传输同步信号块的时频资源来传输其它数据或者调度终端设备进行传输。当网络设备实际发 送的同步信号块的数量小于最大数量时，需要通知终端设备实际发送了哪些同步信号块，以便终端设备能够在准确的时频资源上接收到同步信号块。
在本发明各种实施例中，网络设备以同步信号块组为基础来指示实际发送的同步信号块，下面将对同步信号块的可能分组方式进行简单介绍。以同步信号块突发集中包含的同步信号块的最大数量L＝64为例。
方式一：将64个同步信号块分为16个同步信号块组，每个同步信号块组中包含4个同步信号块，16个同步信号块组的序号依次为0～15，可以用4bit信息表示，每个同步信号块组中包含的4个同步信号块的序号依次为0～3，可以用2bit信息表示。
方式二：将64个同步信号块分为8个同步信号块组，每个同步信号块组中包含8个同步信号块，8个同步信号块组的序号依次为0～7，可以用3bit信息表示，每个同步信号块组中包含的8个同步信号块的序号依次为0～7，可以用3bit信息表示。
方式三：将64个同步信号块分4个同步信号块组，每个同步信号块组中包含16个同步信号块，4个同步信号块组的序号依次为0～3，可以用2bit信息表示，每个同步信号块组中包含的16个同步信号块的序号依次为0～15，可以用4bit的信息表示。
需要说明的是，上述分组方式是示例性的，依据上述分组原则还可以有其它的分组方式，例如可以将64个同步信号块分成32组。另外，每个同步信号块在同步信号块突发集中的序号可以通过同步信号块所在的同步信号块组的序号和同步信号块在该同步信号块组内的序号来确定，以上述分组方式二为例，同步信号块组1的序号可以表示为001，同步信号块组1中同步信号块2的序号可以表示为010，则同步信号块组1中的同步信号块2在同步信号突发集中的序号为001010(同步信号块组的序号的二进制数值作为高位，同步信号块的序号的二进制数值作为低位)，即同步信号块组1中的同步信号块2在同步信号突发集中的序号为10。又例如，同步信号块组7的序号可以表示为111，同步信号块组7中同步信号块2的序号可以表示为010，则同步信号块组7中的同步信号块2在同步信号突发集中的序号为111010，即同步信号块组1中的同步信号块2在同步信号突发集中的序号为58。换句话说，每个同步信号块在同步信号块突发集中的序号的二进制数值中的高位为该同步信号块所在的同步信号块组的序号的二进制数值，每个同步信号块在同步信号块突发集中的序号的二进制数值中的低位为该同步信号块在同步信号块组内的序号的二进制数值。
在本发明各种实施例中，实际发送的各个同步信号块组中实际发送的同步信号块的位置相同，这里的位置相同也可以理解为实际发送的每个同步信号块组中实际发送的同步信号块的序号相同。以上述分组方式三为例来说，同步信号块组0中实际发送的同步信号块的序号为0、1、2、3，同步信号块组1中实际发送的同步信号块的序号为0、1、2、3，此时这两个同步信号块组中实际发送的同步信号块的位置相同，即都是发送的同步信号块组中前4个同步信号块。又例如，同步信号块组0中实际发送的同步信号块的序号为0、2、4、6，同步信号块组1中实际发送的同步信号块的序号为0、2、4、6，此时这两个同步信号块组中实际发送的同步信号块的位置也是相同的。可以理解的是，实际发送的各个同步信号块组中实际发送的同步信号块的序号可以是连续的，也可以是不连续的。
下面将结合附图对本发明实施例提供的同步信号块的指示方法进行详细说明。
图3是本发明实施例提供的一种同步信号块指示方法300的示意性交互流程图。图3中的网络设备可以是图1所示系统中的网络设备102。终端设备可以是图1所示系统中的终端设备104、106、108、110、112和114。在具体实现过程中，网络设备和终端设备的数量可以不局限于本实施例和其它实施例的举例，以下不再赘述。
310，网络设备生成同步信号块指示消息，所述同步信号块指示消息包括同步信号块组指示信息和同步信号块指示信息，所述同步信号块组指示信息用于指示实际发送的同步信号块组，所述同步信号块指示信息用于指示实际发送的各个同步信号块组中实际发送的同步信号块。其中，实际发送的各个同步信号块组中实际发送的同步信号块的位置相同。
在一种可能的设计中，同步信号块组指示信息包括实际发送的同步信号块组的数量信息和配置信息，该数量信息用于指示实际发送的同步信号块组的个数m，该配置信息用于指示实际发送的同步信号块组为所有同步信号块组中前面m个同步信号块组或者最后m个同步信号块组。相应地，同步信号块指示信息可以为位图信息，该位图信息用于指示实际发送的各个同步信号块组中实际发送的同步信号块。在具体实现过程中，由于实际发送的各个同步信号块组中实际发送的同步信号块的位置相同，网络设备可以通过同步信号块组数量信息和配置信息指示实际发送的同步信号块组，通过同步信号块位图信息指示实际发送的各个同步信号块组中实际发送的同步信号块，从而向终端设备指示实际发送的所有同步信号块。以上文中描述的分组方式二为例，同步信号块组的数量信息可以为3bit信息，例如可以为100，同步信号块组的配置信息可以示例性地用表1来描述，可以为1bit信息，例如可以为0，则网络设备实际发送的同步信号块组的数量为4，并且这4个同步信号块组为所有同步信号块组中的前面4个同步信号块组，即同步信号块组0、1、2、3。相应地，同步信号块位图信息可以为比特序列，该比特序列的长度和每个同步信号块组中同步信号块的个数相同，并且比特序列中的每一比特对应一个同步信号块，其中该比特的值为1，则代表对应的同步信号块被发送；如果该比特的值为0，则代表对应的同步信号块没有被发送。具体而言，该同步信号块位图信息可以为8bit序列，例如可以为10100000，则实际发送的每个同步信号块组中实际发送的同步信号块为第1个同步信号块和第3个同步信号块，即同步信号块0和同步信号块2。可以理解的是，当终端设备接收到实际发送的同步信号块组数量信息为100，配置信息为0，同步信号块位图信息为10100000时，终端设备可以确定网络设备实际发送的同步信号块组为所有同步信号块组中的前4个同步信号块组，即同步信号块组0、1、2、3。实际发送的每个同步信号块组中实际发送的同步信号块为第1个同步信号块和第3个同步信号块，即同步信号块0和同步信号块2。应注意，同步信号块组的数量和比特信息对应的二进制数值可以不是一一对应的，例如在上述举例中，当3bit信息为000时可以对应同步信号块组的数量为8，即所有同步信号块组都发送。同步信号块组的数量和比特信息对应的二进制数值的对应关系可以根据实际需要确定，在此不作限定。
需要指出的是，在这种情况下，当采用不同的同步信号块分组方式时，网络设备指示实际发送的同步信号块的开销不同，具体如下，其中，分组方式和上文描述的分组方式相同。
