本公开提供的技术方案适用于5G网络或者其它使用高频波束进行信息传输的网络通信系统。其中,上述高频波束可以是频点在6GHz及以上频段的波束。本公开中涉及的执行主体包括:高频波束的发射端和接收 端,其中,上述高频波束的发射端可以是设置有大规模天线阵列的基站、子基站等。上述高频波束的接收端可以是设置有智能天线阵列的用户设备(User Equipment,UE)。用户设备UE可以是用户终端、用户节点、移动终端或平板电脑等。在具体实现过程中,基站和用户设备各自独立,同时又相互联系,共同实现本公开提供的技术方案。
在介绍本公开技术方案之前,首先了解5G中LTE系统的信息传输方式以及本公开涉及的关于同步信号传输的几个概念。
5G即NR(New Radio)网络相关标准正在3GPP(3rd Generation Partnership Project,第三代合作伙伴计划)中进行。5G网络通信系统的关键技术之一为:波束成形(beamforming)技术。基站NW在对下行同步信号及必要系统信息广播时,5G高频系统中采用了波束扫描的方法,通过集中功率快速扫描覆盖小区,参照图1-1根据一示例性实施例示出的5G系统中高频波束扫描示意图。
5G系统中,关于同步信号的传输,定义了以下三个概念:同步信息块SS block,同步信号突发SS burst和同步信号突发集合SS burst Set。
其中,同步信息块SS block,包括主同步信号(Primary Synchronization Signal,PSS)和辅同步信号(Secondary Synchronization Signal,SSS)。SS block被加载到高频波束中形成SS block波束。基站使用SS block波束对基站信号覆盖小区内的用户设备进行波束扫描,通过下行链路向小区内的用户设备广播同步信息。用户设备接收到上述同步信息块并解析后,实现与小区网络进行信号同步,为UE接入小区网络做准备。
同步信号突发SS burst,是指基站在波束扫描过程中使小区内某一工作频段的用户设备均被SS block波束扫描到,需要依次定向发射的预设数量的SS block波束。参照图1-2根据一示例性实施例示出的SS burst的结构示意图,SS burst可以理解为一组SS block波束,每个SS block波束承载一个SS block。一个SS burst中包括SS block波束的数量与单个波束的发射角度即单个波束的信号覆盖面积有关。一个SS burst中的每一个SS  block波束的频段都相同。
5G系统中,SS burst的发射属于周期性发射,也就是说,基站并不是不间断地发射SS burst,而是每间隔预设时长发射一个SS burst。例如,在一个SS burst发射完成后,间隔5ms再开始发射另一个SS burst。本公开实施例中,可以将相邻两个SS burst的间隔时长表示为SS burst发射周期T1,则上述示例中,T1=5ms。
同步信号突发集合SS burst Set,是指基站要实现5G系统中不同工作频段的用户设备都被SS block波束扫描到,最多需要发射几种SS burst,并根据相邻两个SS burst的间隔时长,即SS burst发射周期T1,确定的一个同步突发集合,对应一个持续时长,可以表示为T0。也就是说,SS burst Set的持续时长与5G系统中规定的通信频段的种类和上述SS burst发射周期T1有关。
假设,5G系统规定了以下四种通信频段:6GHz频段、8GHz频段、10GHz频段、50GHz频段,并且规定了SS burst Set中SS burst发射周期T1为5ms,即相邻两个SS burst的间隔时长为5ms,则在忽略不计SS burst发射时长(相对于SS burst发射周期T1来说,SS burst的发射时长很短,可能是几μs,可以忽略不计)的情况下,一个SS burst Set的持续时长相当于四个SS burst的间隔时长,即20ms,参照图1-3根据一示例性实施例示出的一种SS burst set的结构示意图,该模式的SS burst Set中,每个SS burst的通信频段均不相同,burst 1、burst 2、burst 3、burst 4的通信频段依次变大。
5G系统中,SS burst set的发射属于连续性发射,如图1-4所示。
基于上述技术介绍,本公开提供了一种传输同步信号块的方法,应用于基站中。
参照图2根据一示例性实施例示出的一种传输同步信号块的方法流程图,所述方法可以包括:
在步骤11中,根据预设同步信息块突发集合SS burst Set模式,确 定目标模式索引信息;
本公开实施例中,基站可以采用多种模式的SS burst Set广播同步信息块。在SS burst Set基本信息确定的情况下,每种SS burst Set模式对应的配置信息不同。其中,SS burst Set的基本信息包括:SS burst Set的持续时长T0、包含burst的数量、SS burst发射周期T1。一种SS burst Set模式的配置信息主要包括:burst的种类、每种burst的数量、burst之间的位置关系。
参照图3根据一示例性实施例示出的六种SS burst Set模式的结构示意图,基站可以根据实际需要,采用图3中的一种SS burst Set模式广播同步信息块。
其中,模式一,表示基站在一个SS burst Set持续时长如20ms内,使用相同频段的SS block波束对目标小区进行了四次同步信号扫描。也就是说,对于小区内一个位置不动的用户设备,在20ms内,会在四个不同时刻,被SS block波束覆盖到,其中,每相邻两个时刻的时差为5ms。
模式二和模式三,表示基站在一个SS burst Set的持续时长内,使用相同频段的波束对目标小区进行了两次同步信号扫描。也就是说,对于小区内一个位置不动的用户设备,在20ms内,会在间隔10ms的两个不同时刻,被SS block波束覆盖到。如图3所示,模式二和模式三中的burst 0可以表示其对应的时间段内基站的扫描波束内未配置同步信号块SS block,可以称之为无效burst。
模式二和模式三的不同在于:有效burst即burst 1与无效burst在时域上的位置排列关系不同。
模式四,表示在一个SS burst Set持续时长内,使用了两种频段的SS block波束对目标小区进行了两次同步信号扫描。以6GHz频段和8GHz频段为例,假设burst 1对应6GHz频段,burst 2对应8GHz频段,则模式四说明基站采用6GHz的SS block波束对目标小区扫描一周即完成一次同步信号覆盖后,对应burst 1;间隔T1时长如5ms,再开始采用8GHz的 SS block波束对目标小区扫描一周,对应burst 2。之后,再间隔5ms,开始burst 1的扫描以及间隔5ms进行后续burst 2的扫描。每个burst 1和burst2为一个组合,占用半个SS burst Set持续时长,即10ms。
也就是说,对于一个在小区内位置不动、工作频段为6GHz的用户设备,在20ms内,会在间隔10ms的两个不同时刻,被burst 1中的一个SS block波束覆盖到。同理,对于一个在小区内位置不动、工作频段为8GHz的用户设备,在20ms内,也会在间隔10ms的两个不同时刻,被burst 2中的一个SS block波束覆盖到。
模式五,表示在一个SS burst Set持续时长内,使用了四种频段的SS block波束对目标小区进行同步信号扫描。在20ms内,基站采用每种频段的SS block波束对目标小区进行了一次同步信号覆盖。同理,对于一个在小区内位置不动、工作在某一频段如6GHz的用户设备,只有一次被所需SS block波束扫描到的机会。
模式六,表示在一个SS burst Set持续时长内,基站采用一种频段的SS block波束对目标小区进行了一次同步信号扫描。同理,对于一个在小区内位置不动、工作在对应频段的用户设备,只有一次被SS block波束扫描到的机会。
本公开实施例中,可以采用预设格式及大小的模式索引信息来表示每一种模式类型。可以采用索引信息列表记录SS burst Set模式类型与模式索引信息的对应关系,示例性的,如表一所示:
模式类型 模式一 模式二 模式三 模式四 模式五 模式六
模式索引信息 4/4 2/4 2/4 2/2 1/1 1/4
表一
表一记录了图3所示每种SS burst Set模式对应的模式索引信息。
基于此,参照图4根据一示例性实施例示出的另一种传输同步信息块的方法流程图,上述步骤11可以包括:
在步骤111中,根据预设SS burst Set模式的模式类型查询预置索引 信息列表,获得所述预设SS burst Set模式对应的模式索引信息。
假设,基站准备采用图3中模式一对应的SS burst Set向目标小区传输同步信息块,则根据模式类型即模式一查询上述表一,可确定模式一对应模式索引信息为:4/4。
在步骤12中,将所述目标模式索引信息存储在每个同步信息块中,获得待发送目标同步信息块;
本公开实施例中,基站将其当前使用的SS burst Set模式的模式索引信息存储在每个同步信息块中,以告知用户设备其当前采用了哪种模式的SS burst Set进行同步信号传输。
基站确定的模式索引信息数据量小,占用几个bit即可完全表示,如表一所示,模式索引信息如4/4只需3个bit即可表示完全,可以有效节约无线传输资源。
本公开实施例中,可以采用以下几种方式,将目标模式索引信息存储在每个同步信息块SS block中,获得待发送的目标SS block:
第一种方式,将目标模式索引信息存储在预设SS burst Set模式中每个同步信息块的物理广播信道PBCH中;
在LTE系统中,物理广播信道PBCH用于传输小区的重要参数,比如用于系统信息配置的MIB(Master Information Block,主要信息块)信息,具有最高优先级,因此,采用此方式方便用户设备快速获取同步信息块,提高获取同步信息块的优先级,进而可以提高获取同步信息块的效率。
进一步地,基站还可以将目标模式索引信息存储在物理广播信道PBCH的指定字段中,比如第10~12bit,方便用户设备快速获取目标模式索引信息,进一步提高获取同步信息块的效率。
第二种方式,将目标模式索引信息存储在预设模式SS burst Set中每个同步信息块的其它信道中;
在本公开另一实施例中,基站也可以将目标模式索引信息存储在其它信道中,比如,用于动态广播小区信息比如各种SIB(System Information  Block,系统信息块)的物理信道DBCH中。
同理,基站也可以将目标模式索引信息存储在其它信道的指定位置,以方便用户设备快速找到同步信息块,此处不再赘述。
在步骤13中,通过高频波束向目标小区内的用户设备周期性发送所述目标同步信息块。
基站在生成目标SS block之后,将其加载在预设SS burst Set模式所包含的每个有效burst的高频波束中,形成SS block波束,使用SS block波束对目标小区进行同步信号扫描。
下面结合具体示例说明目标同步信息块的传输过程,假设基站确定要采用图3中SS burst Set模式五向一个目标小区内的用户设备传输同步信息块,其传输过程如下:
假设图1-2所述的burst为模式五中的burst 1,则基站在开始向目标小区发射第一个burst时,首先将模式五的模式索引信息如1/1加载到一个同步信息块中,形成图1-2中的block 1,然后使用对应频段如6GHz的高频波束如图1-1中的beam1,按照一定方向和预设发射角度发射至目标小区,使目标小区对应信号覆盖区域内的用户设备比如UE1可以获取同步信息块SS block 1。同理,依次按照上述方法获取block 2~block n,并采用对应频段如6GHz的高频波束依次发送至目标小区,使目标小区的全部区域都可以被SS block波束覆盖到。在间隔5ms后,按照上述方法采用另一种频段的高频波束发射图3中模式五的burst 2,依次类推,发射完成burst4之后,相当于完成了图1-4中一个SS burst Set的传输。
可见,采用本公开提供的传输同步信息块的方法,在5G系统中同步信号发射模式不统一的情况下,通过采用在SS block中增加模式索引信息的方式,可以使用户设备精确计算接收同步信号的时间,从而快速、准确地获取所需同步信息块,避免采用盲检方式导致设备功耗增加且影响设备工作效率。
参照图5根据一示例性实施例示出的另一种传输同步信息块的方法 流程图,在图2所示实施例的基础上,在步骤11之前,所述方法还可以包括:
在步骤10中,根据目标小区信息确定待发射SS burst Set模式。
一个基站可以覆盖几个小区,比如3个小区,每个小区内的用户设备分布情况可能相同也可能不同。若各小区的UE分布情况类似或相同,基站可以采用统一模式的SS burst Set向各小区传输同步信息块。
但是,如果各小区的UE分布情况不同,采用统一模式的SS burst Set可能会造成无线资源浪费或者无法使小区内的全部UE获取到同步信息块。
基于此,本公开实施例中,在基站向目标小区发射SS block之前,可以首先根据目标小区信息为目标小区选取合适的SS burst Set模式。
参照图6根据一示例性实施例示出的另一种传输同步信息块的方法流程图,所述步骤10可以包括:
在步骤101中,获取目标小区信息,所述目标小区信息至少包括以下一项:小区标识、小区中的用户设备类型、小区业务的繁忙程度;
在步骤102中,根据所述目标小区信息确定适合目标小区的SS burst Set模式。
本公开实施例中,一个目标小区的小区信息可以包括以下至少一项:小区标识、小区中的用户设备类型、小区业务的繁忙程度。
步骤102的实施可以包括但不限于以下几种情况:
第一种情况,根据目标小区的小区标识确定SS burst Set模式。假设目标小区信息仅包括小区标识。
基站在系统初始化时,可以根据各小区的类型预置一个同步模式列表。假设上述小区类型分为专用设备小区和普通小区。则基站在初始化时可以根据小区类型为各小区标识指定SS burst Set模式。仍以一个基站覆盖三个小区为例,包括:小区A、小区B、小区C。若小区A和B为普通小区,即该小区需要满足各频段的用户设备通信;小区C为专用设备小区, 比如为了特定需求比如保密需求,该小区仅允许某一特定频段如6G的用户设备通信,不允许其它工作频的用户设备接入。若基站可以采用的SS burst Set模式如图3所示,则上述预置同步模式列表可以如表二所示:
Figure PCTCN2017078439-appb-000001
表二
若目标小区的小区标识为A,则通过查询表二可知,基站可以采用图3中模式五代表的SS burst Set向小区A内的用户设备发送SS block。
第二种情况,根据目标小区的用户设备类型确定SS burst Set模式。此种情况下,目标小区信息至少包括:小区允许接入用户设备的设备类型。
基站在确定目标小区标识之后,根据小区的历史信息记录,发现一段时间内,比如该小区在第一季度仅有两种频段的用户设备接入,则基站可以根据上述信息,在第一季度采用图3中的模式四代表的SS burst Set向目标小区内的用户设备广播SS block。
第三种情况,根据小区业务繁忙程度确定SS burst Set模式。
此种情况主要针对目标小区仅允许接入一种频段的用户设备的情况。基站可以根据小区业务的历史信息记录,确定目标小区在各个时间段的业务繁忙情况,进而采用不同SS burst Set模式。从表二可知,目标小区C可以采用模式一、模式二、模式三、模式六发送SS block。假设,历史统计显示,小区C在一天中的8:00~12:00业务繁忙程度最高,12:00~22:00业务繁忙程度为中等,在22:00~8:00业务繁忙程度最低,则基站可以在不同时间段采用不同的SS burst Set模式下发SS block,如表三所示:
时间范围 业务繁忙程度 模式类型
8:00~12:00 高级 模式一
12:00~22:00 中级 模式二、模式三
22:00~8:00 低级 模式六
表三
从表三可知,基站可以根据小区业务的繁忙程度适用性采用合适的SS burst Set模式下发SS block,从而有效节约同步信息块占用的无线资源,提高无线资源的利用率,也可以减少基站的功耗。
相应的,本公开还提供了一种获取同步信息块的方法,应用于用户设备中。
参照图7根据一示例性实施例示出的一种获取同步信息块的方法流程图,可以包括以下步骤:
在步骤21中,按照预设初始检测窗口检测高频波束承载的同步信息块;
用户设备进入目标小区之后,会开启预设的初始检测窗口,比如时长为5ms的检测窗口,进行同步信息块的盲检,以便快速检测到第一个同步信息块。
关于如何确定UE的初始检测窗口,本公开实施例中,初始检测窗口的大小一般根据一个SS burst Set中包括不同频段的burst的数量来确定,即根据图3中模式五代表的SS burst Set来确定初始检测窗口。仍然假设一个SS burst Set的持续时长T0为20ms,模式五代表的SS burst Set包括四个burst,则可以将初始检测窗口的大小确定为5ms,考虑到实际检测中需要留有一定的余量,实际窗口可以稍大于5ms,可以表示为5ms+。
在步骤22中,从检测到的同步信息块中获取SS burst Set的模式索引信息;
本公开实施例中,基站发射的一种SS burst Set模式中的每一个SS block中均包括该SS burst Set的模式索引信息。
所以,用户设备在检测同步信息块之后,可以按照预设模式索引信息存储协议,从同步信息块的预设位置,比如物理信道PBCH中、其它预设信道中、或者上述预设信道的指定字段中解析SS burst Set的模式索引信 息。
本公开实施例中可以采用以下至少两种方式从同步信息块中获取SS burst Set的模式索引信息:
第一种方式,UE在检测到第一个同步信息块之后,按照预设的模式索引信息存储协议,从该第一个同步信息块中获取SS burst Set的模式索引信息。
第二种方式,UE从检测到的多个同步信息块中获取SS burst Set的模式索引信息。参照图8根据一示例性实施例示出的另一种获取同步信息块的方法流程图,上述步骤22可以包括以下步骤:
在步骤221中,从检测到的预设数量的同步信息块中,解析每一个模式索引信息;
本公开实施例中,UE可以连续获取预设数量的同步信息块,比如4个,从每一个同步信息块中获取所属SS burst Set的模式索引信息。
在步骤222中,将预设数量的模式索引信息中相同的模式索引信息,确定为有效模式索引信息。
通过步骤221共获得4个模式索引信息,正常情况下,这4个模式索引信息应该是相同的,但考虑到UE在解码中有可能出现错误,比如将模式索引信息2/4解析成4/4。为了避免上述解析错误导致预计的后续同步信息块达到时间不准确,本公开实施例中,将解析后的预设数量的模式索引信息中相同的信息确定为有效模式索引信息,提高模式索引信息的准确性。
在步骤23中,根据所述模式索引信息确定后续同步信息块的预计到大时间;
上述模式索引信息可以是用户设备按照第一种方式确定的模式索引信息,也可以是用户设备按照上述第二种方式确定的有效模式索引信息。
参照图9根据一示例性实施例示出的另一种获取同步信息块的方法流程图,上述步骤23可以包括以下步骤:
在步骤231中,根据所述模式索引信息确定两个相邻同步信息块的时间间隔;
UE在获取了模式索引信息之后,即可根据同步信息块所属的SS burst Set的模式类型计算出相邻两个同步信息块之间的时间间隔,也就是相邻两个相同的同步突发burst之间的时间间隔。
假设,UE获取的模式索引信息为:1/1,对应图3中模式五表示的SS burst Set,则可确定相邻两个相同的同步突发的时间间隔为20ms。同理,若所述模式索引信息为:4/4,对应图3中模式一表示的SS burst Set,则相邻两个相同的同步突发的时间间隔为5ms。依次类推,若将相邻两个相同的同步突发的时间间隔表示为T2,则可以示例性地采用以下表四记录模式索引信息、SS burst Set模式类型、T2之间的对应关系:
模式类型 模式一 模式二 模式三 模式四 模式五 模式六
模式索引信息 4/4 2/4 2/4 2/2 1/1 1/4
T2 5ms 10ms 10ms 10ms 20ms 20ms
表四
在步骤232中,根据当前同步信息块的接收时刻和所述两个相邻同步信息块的时间间隔,确定后续同步信息块的预计达到时间。
假设UE1在t1时刻检测到第一个同步信息块,比如是图1-2中所示的block 2,并且解析出的模式索引信息为2/4,通过查询表四可知,该模式中相邻两个block 2到达UE1的时间间隔为:10ms。也就是说UE1可以在t1+10ms时刻通过检测窗口检测到第二个同步信息块block 2,依次类推,计算后序block 2到达UE1的时刻。
在步骤24中,在后续信号同步过程中,按照所述预计达到时间获取目标同步信息块。
需要注意的是,在实际应用中,UE并不会在每个同步信息块达到的时刻都会开启检测窗口进行检测,而是根据按照预设策略进行信息同步, 比如每间隔2个同步信息块检测一次,则UE可以根据上述信息计算检测窗口的开启时间。仍以上述UE1为例,UE1在t1时刻检测到第一个同步信息块之后,可以按照预设策略比如每间隔2个同步信息块检测一次,则UE1可以以t1+30ms时刻为中心,开启预设宽度的同步信息检测窗口检测下一个目标同步信息块。同理,根据目标同步信息块的预计达到时间确定检测窗口的开启时间,依次检测目标同步信息块。
可见,采用本公开实施例提供的获取同步信息块的方法,用户设备可以首先从检测到的同步信息块中获取模式索引信息,以确定基站是采用何种模式的同步信息突发集合向所在小区广播同步信息,进而可以计算出每相邻两个同步信息块的时间间隔,从而估算后续同步信息块的接收时间,避免采用采用盲检方式进行同步信号检测,有效节约用户设备的无线资源,同时减少用户设备功耗。
