Description

同步信号块的定时方法及相关产品 技术领域
本申请涉及通信技术领域，尤其涉及一种同步信号块的定时方法及相关产品。
背景技术
同步信号是给需要同步处理信息的机器设备提供相同时间参考的信号。新空口(New Ratio，NR)/5G的Multi-beam(多波束)系统通过不同的beam(波束)来覆盖整个小区。每个beam对应一个同步信号块(SS block)，SS block至少包括主同步信号(Primary Synchronization Signal，PSS)、辅同步信号(Secondary Synchronization Signal，SSS)和物理广播信道(Physical Broadcast Channel，PBCH)，PBCH还含有用于解调的解调参考信号(DMRS)。
目前，在NR的讨论中，SS block索引(index)是携带在PBCH中的，当用户设备(User Equipment，UE)检测到一个SS block并成功解调了PBCH之后，UE就能获得SS block的index。但是在某些场景下，即使UE知道了SS block的index，UE还是可能无法知道SS block的符号(symbol)级别的定时和子帧(SF)级别的定时。由于获得准确的定时，如symbol级别和SF级别的定时是UE搜索小区的第一步，因此UE如何获得SS block的准确定时是需要解决的技术问题。

下面结合图1所示的网络构架对本申请实施例提供的同步信号块的定时方法进行详细说明。
请参见图2a，图2a为本申请实施例提供的一种同步信号块的定时方法的流程示意图，包括以下步骤：
S201、网络设备向用户设备发送SS block的定时信息。
在一示例中，所述SS block的定时信息是所述网络设备在物理广播信道(PBCH)和/或最小系统信息(minimal SI)中提供的。
具体地，由于PBCH是用户设备在小区搜索时最先就能检测的信道，网络设备将SS block的定时信息在PBCH中提供，这样用户设备能够在最短的时间内获得SS block的定时信息，有利于用户设备节约在小区搜索时消耗的能量，同时还有利于用户设备简化小区搜索的设计，否则的话，用户设备必然要通过检测其它信道获得SS block的定时。
另外，在目前的5G/NR系统中，用户设备在做初始小区搜索必须知道的信息组成了minimal SI。网络设备将SS block的定时信息通过minimal SI提供给用户设备，可节省调度信令，另外，可使得用户设备在做初始小区搜索时即可获得SS block的定时信息。
此外，minimal SI中相对重要的部分信息是在PBCH中传输的，剩下的部分信息由PBCH指示其它信道传输。比如，minimal SI包括信息A和B，信息A比信息B重要，网络设备通过PBCH传输信息A，后续用户设备监听PBCH时即可获得信息A，另外网络设备通过PBCH传输一指示信息，该指示信息用于指示信息B在其他信道(除了PBCH之外的信道)中传输，后续用户设备监听PBCH时即可获得该指示信息，通过该指示信息用户设备可知道信息B具体在哪些信道传输。另外，minimal SI中相对重要的部分信息可由网络设备根据不同的功能进行确定，比如，在本申请实施例中，携带有SS block的定时 信息的信息比较重要。或者，minimal SI中相对重要的部分信息可由网络设备自定义的，等等，本申请不作限定。
在一示例中，所述SS block的定时信息是所述网络设备通过专用信令提供的。所述专用信令例如可以是RRC连接重配置(RRC Reconfiguration)信令。可见，通过专用信令发送SS block的定时信息可保证SS block的定时信息准确性。
S202、所述用户设备接收网络设备发送的SS block的定时信息，所述用户设备根据所述SS block的定时信息确定SS block的定时。
在一示例中，所述SS block的定时信息包括以下几种情况中的至少一种：
1)所述SS block所用的配置方式；
2)所述SS block的索引(index)；
3)所述SS block在所属的SS burst set中所在的时域位置；
4)在时域上相邻的两个SS block的距离；
5)在一个SS burst set周期中包含的SS block数目。
需要说明的是，当SS block的定时信息是由网络设备在PBCH提供的，且SS block的定时信息包括以上5种信息中的至少2种信息时，网络设备可以在同一时刻将这至少2种信息在PBCH中广播，或者，网络设备不在同一时刻将这至少2种信息在PBCH中广播等等，本申请不作限定。
另外，当SS block的定时信息是网络设备在minimal SI提供的，且SS block的定时信息包括以上5种信息中的至少2种信息时，网络设备将这至少2种信息同时携带在minimal SI中的一条信息中，或者，网络设备不将这至少2种信息同时携带在minimal SI中的一条信息中等等，本申请不作限定。
另外，当SS block的定时信息是网络设备在PBCH和minimal SI提供的，且SS block的定时信息包括以上5种信息中的至少2种信息时，网络设备将这至少2种信息中的一部分携带在minimal SI中，剩下的一部分在PBCH中广播等等，本申请不作限定。
在一示例中，所述SS block所用的配置方式是预先约定的。SS block所用的配置方式可以是网络设备和用户设备预先约定的，或是协议中预先约定的，本申请不作限定。
在一示例中，所述SS block所用的配置方式是所述SS block在所属的SS burst set中时域上的位置关系。
具体地，如图2b所示，在一个SS burst set周期内，譬如20ms，在一个SS burst set周期中假设包含的2个SS block，2个SS block可能的排列方式是有限的。如图2b所示，在一个SS burst set周期中假如含有两个SS block，且有配置方式1和配置方式2两种排列方式。如图2b所示，配置方式1中SS block在所属的SS burst set中时域上的位置关系有：SS block#1的起始位置与SS burst set的起始位置重合，SS block#2的起始位置与SS block#1终止位置X个OFDM symbol等等。配置方式2中SS block在所属的SS burst set中时域上的位置关系有：SS block#1的起始位置距离SS burst set的起始位置Y个OFDM symbol，SS block#2的起始位置与SS block#1的终止位置距离Z个OFDM symbol等等。
需要说明的是，上述描述的SS block在所属的SS burst set中时域上的位置关系仅仅只是一种示例，对于SS block在所属的SS burst set中时域上的位置关系的具体呈现方式，本申请不作限定。
举例来说，假设一个SS burst set周期，譬如20ms，在一个SS burst set周期中包含的2个SS block，SS block所用的配置方式为图2b所示的配置方式1，SS block的index为SS block#1，配置方式1是协议中预先约定的，当用户设备接收到网络设备发送的上述信息后，用户设备就能依据事先约定的SS block的配置方式1知道SS block#1的准确的定时。另外，由于SS block的配置方式1中给出了SS burst set中SS block#2的时域位置关系，用户设备在得到SS block#1的准确的定时后，用户设备可根据SS block#1的准确的定时得到SS block#2的准确的定时，进而加快了用户设备搜索SS block的速度。
在一示例中，当所述SS block的定时信息包括所述SS block在所属的SS burst set中所在的时域位置时，所述SS block的定时信息还包括所述SS block所在的帧号，或者，所述SS block的定时信息还包括所述SS block所在的符合(symbol)的时域位置。
在一示例中，所述SS block所在的symbol时域位置用于定义所述SS block起始位置所在的symbol的时域位置，和/或所述SS block所在的symbol时域 位置用于定义所述SS block终止位置所在的symbol的时域位置。
在一示例中，所述SS block所在的帧号用于定义所述SS block起始位置所在的帧号，和/或所述SS block所在的帧号用于定义所述SS block终止位置所在的帧号。
举例来说，在某些情况下，如预先约定好SS block所用的配置方式可能会对网络设备在配置同步信号时构成一定的限制。譬如在5G系统中，在高频段可能更多的是时分双工(Time Division Duplexing，TDD)系统。而在TDD系统中，系统需要能按小区内不同的业务类型去动态的调整上下行帧比例。由于同步信号只能在下行帧上发送，假如预先约定好SS block所用的配置方式，有可能会对系统的调度产生限制。
为了避免上述情况，网络设备可以直接在PBCH或minimal SI中通知用户设备SS block在SS burst set中所在的时域位置。如图2c所示，一个周期为20ms的SS burst set里有2个SS block，每个SS block在时域上持续4个OFDM symbol。SS block#1从SS burst set的起始位置开始，SS block#2的起始位置距离SS block#1的结束位置在时域上为t个OFDM symbol。以图2c为例，symbol为单位，网络设备可以直接在PBCH或minimal SI中通知用户设备SS block#1在SS burst set中的位置是0，或者网络设备可以直接在PBCH或minimal SI中通知用户设备SS block#2在SS burst set中的位置是t+4，可见，SS block 2的起始位置位于SS burst set起始位置后的t+4个OFDM symbol。用户设备接收到网络设备通知的SS block#1在SS burst set中的位置为0时，用户设备可知道SS block#1从SS burst set的起始位置开始，或者，用户设备接收到网络设备通知的SS block#1在SS burst set中的位置为t+4时，用户设备可知道SS block#2从SS burst set起始位置后的t+4的位置开始。
其中，每个SS block在时域上持续的symbol的持续时间，如上述所述的每个SS block在时域上持续4个OFDM symbol，具体的持续时间可以是在协议中预先规定好的，也可以是包含在SS block的定时信息中的，本申请不作限定。
有时，用户设备除了要知道SS block在所属的SS burst set中所在的时域位置，也需要知道SS block所在的整个帧结构中的位置。所以网络设备在PBCH 或minimal SI中除了通知用户设备SS block在所属的SS burst set中所在的时域位置，还可以通知用户设备SS block所在的帧号，譬如SF index(在5G系统中，一个SF被定义为时域宽度为1ms)。在图2c中，SS block 1所在的帧号是SF i；SS block 2所在的帧号是SF j。SS block所在的帧号可以定义为SS block起始位置所在的帧号，也可以定义为结束位置所在的帧号。需要这个定义是由于有的SS block可能跨越前后两个SF。
或者，用户设备除了要知道SS block在所属的SS burst set中所在的时域位置，也需要知道SS block所在的symbol时域位置。所以网络设备在PBCH或minimal SI中除了通知用户设备SS block在所属的SS burst set中所在的时域位置，还可以通知用户设备SS block所在的symbol时域位置，在图2c中，SS block#1所在的symbol在第一个symbol到第四个symbol，SS block#2所在的symbol在第t+4个symbol到第t+8个symbol。SS block所在的symbol时域位置可以定义为SS block起始位置所在的symbol，也可以定义为终止位置所在的symbol。需要这个定义是由于有的SS block可能跨越前后两个SF。
又举例来说，为了加快用户设备搜索SS block的速度，网络设备除了指示用户设备SS block在所属的SS burst set中所在的时域位置，也可以指示在SS block所属的SS burst set内，在时域上相邻的两个SS block的距离。譬如，对于图2c的SS block#1,在时域上相邻的两个SS block的距离为是t，表明从当前SS block结束位置后t个OFDM symbol是SS block#2，这样当用户设备知道SS block#1的准确定时后，用户设备知道SS block#2的准确定时。
另外，假如SS block index为SS block#2，由于它已经是SS block#2所属的SS burst set的最后一个SS block，该种情况下，有两种办法指示，一个就是不指示，或是置为0，用于表示当前SS block已经是当前SS block所属的SS burst set的最后一个SS block。还有就是指示从当前SS block到下一个SS burst set的第一个SS block的时域距离(也就是时域上下一个SS block的距离)。在图2c中，SS block#2到下一个SS burst set的距离是q个symbol，所以在时域上相邻的两个SS block的距离为是q，这样当用户设备知道SS block#2的准确定时后，下一个SS burst set的第一个SS block的准确定时。
在本方案中，用户设备是基于网络设备发送的定时信息对SS block进行定 时的，相较于现有技术只通过SS block index对SS block进行定时，本方案更能获得SS block的准确定时。
