具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
相关技术中,基站(NB)全向发送同步信号块(SS block,Synchronization Signal block),在4个周期内重复发送4次。相邻两个同步信号块之间相隔一个周期。用户设备(UE)位于小区的中心区域时,接收的信号质量较好。用户设备根据一个同步信号块便可对其中的PBCH(物理广播信道)进行成功解码。如果用户设备位于小区边缘,接收的信号质量较差,对一个同步信号块中的PBCH进行解码,很可能会失败。为解决该问题,用户设备可以将两个周期的两个同步信号块中的PBCH进行软合并,然后对软合并后的PBCH进行解码,可提高解码的成功率。
相关技术中提出了波束定向发送同步信号块。基站一次在一个波束方向上发送同步信号块,在一个同步信号突发集合(SS burst set,Synchronization Signal burst set)内,遍历所有波束定向,也就是说在每个波束定向上发送一次同步信号块。在一个同步信号突发集合内保证在所有波束方向上扫描一周,并且在一个同步信号突发集合内网络侧会在至少两个波束方向上发送基本相同的同步信号块(两个同步信号块之间,除波束索引信息以外的广播数据均相同)。如图1所示,每个同步信号块上方的箭头表示波束方向,图1中以4个波束方向为例。相邻两个同步信号块在位置上可能紧密相连,也可能有一定的距离。
如果用户设备位于波束的正方向上,如图2所示,可接收到质量较好的信号,根据该方向上的同步信号块可成功解码PBCH。如果用户设备位于两个波束方向之间,如图3所示,接收的信号质量较差,可能无法成功解码PBCH。
为解决该问题,本实施例采用对PBCH进行软合并的方案。在全向发送同步信号块的场景中,将两个周期的两个同步信号块中的PBCH进行软合并。而在波束定向发送同步信号块的场景中,两个周期的两个同步信号块可能是不同的同步信号块,因此不能将两个周期的两个同步信号块中的PBCH进行软合并。本实施例提供了将一个同步信号突发集合内的两个 同步信号块中的PBCH进行软合并的方案。
图4是根据一示例性实施例示出的一种物理广播信道的处理方法的流程图,该物理广播信道的处理方法用于用户设备中,其中,用户设备可以是移动电话等具有移动通信功能的设备。如图4所示,该方法包括以下步骤401-404。
在步骤401中,根据预设的同步信号的位置,从获得的子帧中识别同步信号。
在步骤402中,在识别出同步信号时,确定第一同步信号块。
在步骤403中,在所述第一同步信号块所属的同步信号突发集合内,再次识别出同步信号时,确定第二同步信号块。
在步骤404中,将所述第一同步信号块和所述第二同步信号块中的物理广播信道(PBCH)进行软合并。
本实施例通过同步信号确定第一同步信号块,以及以同样方式在同一同步信号突发集合内确定第二同步信号块。本实施例支持在同一同步信号突发集合内确定两个同步信号块,从而支持同一同步信号突发集合内两个同步信号块中的PBCH的软合并。提高了用户设备解码PBCH的成功率。当然,还可以将同一同步信号突发集合内三个或三个以上同步信号块中的PBCH的软合并。以提高解码PBCH的成功率。
本实施例中,用户设备可以开机(或重启等)后立刻确定同一同步信号突发集合内的两个同步信号块,并进行PBCH的软合并。提高了解码PBCH的成功率。以及减少时延。
本实施例中,用户设备可以开机后立刻确定同一同步信号突发集合内的两个同步信号块,对两个同步信号块分别进行单独解码,同时对两个同步信号块的PBCH进行软合并和解码。有一个解码成功,便可获得PBCH上的数据。多个解码方案同步进行,提高了解码PBCH的成功率。减少时延。
本实施例中软合并有多种实现方式,例如将第一同步信号块和所述第二同步信号块中的PBCH按照对应的比特位,进行比特软信息相加再取平均。其它软合并算法也适用于本实施例。
本实施例中同步信号包括主同步信号(PSS)和辅同步信号(SSS),在确定主同步信号和辅同步信号的位置后,便可定位同步信号块。
本实施例中系统可以固定配置同步信号的位置,例如主同步信号的位置在子帧中的第3个符号(OFDM(Orthogonal Frequency Division Multiplex,正交频分复用)符号)和/或第7个符号。辅同步信号的位置在子帧中的第5个符号和/或第9个符号。
在一个实施例中,步骤403包括:步骤A1-步骤A2。
在步骤A1中,从所述第一同步信号块开始向后再次识别同步信号。
在步骤A2中,再次识别出同步信号时,确定第二同步信号块。
本实施例中用户设备开机后从获得的第一个子帧开始,从前向后识别同步信号,在识别出第一个同步信号时,可确定第一同步信号块。然后继续向后识别同步信号,再次识别出同步信号时,确定第二同步信号块。本实施例开机后立刻处理,时延较小。
在一个实施例中,步骤401包括:步骤B1-步骤B2。
在步骤B1中,接收并缓存预设时长的子帧;所述预设时长小于一个周期。
在步骤B2中,根据预设的同步信号的位置,从缓存的最后一个子帧的结束位置,向前识别同步信号。
步骤403包括:步骤B3-步骤B4。
在步骤B3中,在缓存的子帧中,从所述第一同步信号块开始向前再次识别同步信号。
在步骤B4中,再次识别出同步信号时,确定第二同步信号块。
本实施例中用户设备开机后先接收并缓存预设时长的子帧。例如,一个周期为20ms,预设时长为10ms。缓存10ms的子帧后,开始从缓存的最后一个子帧的结束位置,向前识别同步信号。也就是从第10ms所对应的子帧的结束位置向前识别同步信号。识别出第一个同步信号时,可确定第一同步信号块。然后继续向前识别同步信号,再次识别出同步信号时,确定第二同步信号块。
如果第一同步信号块与第二同步信号块进行PBCH软合并并解码后失败,可以将第二同步信号块作为第一同步信号块,继续向前确定第三同步信号块(作为第二同步信号块)。将第二同步信号块与第三同步信号块进行PBCH软合并和PBCH解码。直至解码成功或向前不再有同步信号块。
在向前识别第一个同步信号时,可继续接收并缓存子帧。如果向前未再次识别出同步信号,或者第一同步信号块与第二同步信号块进行PBCH软合并并解码后失败,则从所述第一同步信号块开始向后再次识别同步信号。
在一个实施例中,所述方法还包括:步骤C。
在步骤C中,对软合并后的PBCH进行解码。
在一个实施例中,所述方法还包括:步骤D1-步骤D4。
在步骤D1中,在对软合并后的PBCH进行解码失败时,从所述第一同步信号块开始,接收并缓存一个周期的子帧。
在步骤D2中,确定与所述第一同步信号块相隔一个周期的第三同步信号块。
在步骤D3中,在缓存的一个周期的子帧中,在所述第三同步信号块所属的同步信号突发集合内,从所述第三同步信号块开始向前获取第四同步信号块。
在步骤D4中,将所述第三同步信号块和所述第四同步信号块中的PBCH进行软合并。
本实施例中,第一同步信号块与第二同步信号块进行PBCH软合并后解码,有可能解码失败。说明第一同步信号块与第二同步信号块不在同一同步信号突发集合内。如果用户设备从第一同步信号块向后确定的第二同步信号块,则用户设备应向前查找第二同步信号块。如果用户设备缓存了第一同步信号块位置之前的子帧,则可以向前查找第二同步信号块,并再次尝试PBCH软合并和解码。如果用户设备没有缓存第一同步信号块位置之前的子帧,则向后查找与所述第一同步信号块相隔一个周期的第三同步信号块。由于第三同步信号块与第一同步信号块相隔一个周期,所以比较容易确定第三同步信号块,不需要逐个符号的 识别同步信号。因为之前向后查找并确定的第二同步信号块与第一同步信号块不在同一同步信号突发集合内。因此,在确定第四同步信号块时,从所述第三同步信号块开始向前获取第四同步信号块。这样确定的第四同步信号块与第三同步信号块在同一同步信号突发集合内。有助于提高PBCH解码的成功率。
在一个实施例中,所述方法还包括:步骤E。
在步骤E中,在对软合并后的PBCH进行解码成功时,从所述第一同步信号块和所述第二同步信号块的PBCH中,获取相同的数据部分。
本实施例中第一同步信号块与第二同步信号块的PBCH中,波束索引和序号等系统信息不同,用户数据部分相同,因此获取相同的数据部分,其余部分可丢弃。用户设备可以选择第一同步信号块和第二同步信号块中的任一个同步信号块确定自身位置,以便与系统保持同步。例如,用户设备选择第一同步信号块和第二同步信号块中信号强度较高的同步信号块确定自身位置。
在一个实施例中,再次识别出同步信号时,确定第二同步信号块之前,所述方法还包括:步骤F1-步骤F2。
在步骤F1中,获取当前的信号强度。
在步骤F2中,判断所述信号强度是否大于预设的信号强度阈值。
步骤403包括:步骤F3。
在步骤F3中,在所述信号强度不大于预设的信号强度阈值时,以及再次识别出同步信号时,确定第二同步信号块。
本实施例中,如果用户设备每次都采用软合并方案,可能功耗较大。因此,本实施例可先判断当前的信号强度是否大于预设的信号强度阈值。如果大于预设的信号强度阈值,说明信号质量较好,PBCH解码的成功率较高,可以不采用软合并方案,而是对单一同步信号块中的PBCH进行解码。如果不大于预设的信号强度阈值,说明信号质量较差,PBCH解码的成功率较低,需要采用软合并方案。
如果用户设备没有大距离移动,基本驻留在一个位置,还可以通过上一次是否采用软合并方案,来确定本次是否采用软合并方案。如果上一次采用软合并方案,则本次也采用软合并方案。如果上一次没有采用软合并方案,则本次也不采用软合并方案。
在一个实施例中,再次识别出同步信号时,确定第二同步信号块之前,所述方法还包括:步骤G1-步骤G2。
在步骤G1中,根据所述第一同步信号块中同步信号的位置,以及根据预设的PBCH与同步信号的相对位置关系,确定PBCH在所述第一同步信号块中的PBCH位置。
在步骤G2中,根据所述PBCH位置,对所述第一同步信号块中的PBCH进行解码。
再次识别出同步信号时,确定第二同步信号块,包括:步骤G3。
在步骤G3中,对所述第一同步信号块中的PBCH解码失败时,以及再次识别出同步信号时,确定第二同步信号块。
本实施例中,同步信号的位置是固定配置的,同一同步信号块中同步信号与PBCH之间的相对位置关系也是固定配置的。例如,同一同步信号块中同步信号后面的符号即为PBCH。确定PBCH的位置后,便可对PBCH进行解码。如果解码失败,说明信号质量较差,需采用软合并的方案,则再次识别出同步信号时,确定第二同步信号块。本实施例不一定每次都采用软合并方案,可兼容对单一同步信号块中PBCH解码的方案。有助于减少时延和提高解码的成功率。
