图1为本申请提供的一种信息的传输方法的流程示意图。本实施例涉及的是UE如何根据服务小区的子载波间隔,确定服务小区的系统参数的过程。如图1所示,该方法包括:
S101、UE确定服务小区的子载波间隔。
具体的,上述UE可以确定服务小区(serving cell)的子载波间隔,也就是用户设备对应的服务小区的子载波间隔。其中,这里所说的用户设备对应的服务小区可以为网络设备为UE配置的服务小区,还可以为正在为UE服务的服务小区,还可以为UE正在接入的服务小区。上述所说的服务小区可以为UE的主服务小区(Primary serving cell),也可以为UE的辅服务小区(Secondary serving cell)。在本申请的一种实现方式中,上述服务小区(serving cell)还可以称为载波(carrier),即一个服务小区就是一个载波。
可选的,上述UE可以根据服务小区的载波频率,确定服务小区的子载波间隔,还可以根据服务小区对应的频率集合,确定服务小区的子载波间隔。UE确定服务小区的子载波间隔的实现方式将在后文中进行详细描述。
另外,UE还可以采用现有的确定服务小区的子载波间隔的方式,本申请对此不再赘述。
S102、UE根据服务小区的子载波间隔,确定服务小区的系统参数。
具体的,UE可以根据预设的子载波间隔与系统参数之间的对应关系以及服务小区的子载波间隔,确定服务小区的系统参数;还可以根据服务小区的子载波间隔计算系统参数,并将计算得出的系统参数作为服务小区的系统参数。当然,UE根据服务小区的子载波间隔,还可以采用现有的方式确定服务小区的系统参数,对此本申请不再赘述。其中,上述所说的服务小区的系统参数可以包括子帧长度、一个子帧包括的符号个数、有效符号长度、循环前缀(Cyclic Prefix,CP)长度等参数中的一个或多个。
以UE根据预设的子载波间隔与系统参数之间的对应关系以及服务小区的子载波间隔,确定服务小区的系统参数为例,具体实施时,当上述UE确定服务小区的子载波间隔之后,就可以根据该子载波间隔,在预设的对应关系中查找与该子载波间隔对应的系统参数,所查找到的系统参数即为服务小区的系统参数。其中,上述预设的对应关系可以根据用户的需求进行设置。示例性的,上述预设的映射关系可以如下述表1和表2所示。需要说明的是,表1和表2中的数值仅为举例,表1和表2中的数值还可以为四舍五入后的值,例如,本实施例中的有效符号长度和CP长度可以为近似于表中的数值的数。另外,不限定表中各参数间的相互依赖关系。
表1

Figure PCTCN2017076619-appb-000002
表2
Figure PCTCN2017076619-appb-000003
其中,例如表1中所示,当子载波间隔为15kHz时,UE的系统参数可以为系统参数1。该系统参数1中包括:子帧长度为1ms,符号个数为14个或12个,有效符号长度为66.67μs,CP长度为4.76μs或16.67μs,CP开销为小于等于6.7%。
需要说明的是,上述表1中示出的系统参数所对应的子载波间隔为15kHz的倍数,以使得这些系统参数和子载波间隔可以匹配部分现有LTE系统。上述表2中示出的系统参数5对应于子载波间隔为17.5kHz,以使得该系统参数和子载波间隔可以支持较短的发射间隔时间(Transmission Time Interval,TTI)长度,例如0.125ms的TTI长度。其中,不同的TTI长度下可以保持GP开销一致。
S103、UE根据服务小区的系统参数,在服务小区上向网络设备发送信息,或,接收网络设备发送的信息。
具体的,当UE获取到服务小区的系统参数之后,就可以使用该系统参数,在服务小区上与网络设备进行信息的传输。例如:UE可以根据服务小区的系统参数,在服务小区上向网络设备发送信息,该信息例如可以为上行数据、上行控制信息等。UE还可以根据服务小区的系统参数,在服务小区上接收网络设备发送的信息,该信息例如可以为下行数据、下行控制信息、下行参考信号等。
本申请提供的信息的传输方法,当服务小区在不同的业务、不同的部署场景、不同的频谱下,使用不同的系统参数时,UE可以通过服务小区当前所使用的子载波间隔确定服务小区当前所使用的系统参数,从而使得UE可以使用该系统参数,在服务小区上与网络设备进行信息的传输,提高了信息的传输效率。
进一步地,在上述实施例的基础上,本实施例涉及的是上述UE如何确定服务小区的子载波间隔的具体过程,则上述S101可以包括如下三种实现方式:
第一种实现方式:UE根据服务小区对应的频率集合,确定服务小区的子载波间隔。图2为本申请提供的另一种信息的传输方法的流程示意图,如图2所示,该方法可以包括:
S201、UE确定服务小区对应的频率集合。
具体的,UE确定服务小区对应的频率集合,可以为UE根据所述服务小区的载波频率确定所述服务小区的频率集合,例如上述UE可以将服务小区的载波频率所处的频率集合确定为服务小区对应的频率集合;还可以根据预设的服务小区与频率集合的对应关系,确定服务小区对应的频率集合,例如可以根据预设的服务小区的标识与频率集合的对应关系,以及,服务小区的标识,确定服务小区对应的频率集合。
S202、UE根据服务小区对应的频率集合,确定服务小区对应的子载波间隔集合。
具体的,上述UE可以根据服务小区对应的频率集合,在预设的频率集合与子载波间隔集合的对应关系中查找与该服务小区对应的频率集合对应的子载波间隔集合,该子载波间隔集合即为服务小区对应的子载波间隔集合;还可以根据服务小区对应的频率集合,计算子载波间隔集合,并将计算出的子载波间隔集合作为服务小区对应的子载波间隔集合等。
当上述UE根据服务小区对应的频率集合和预设的频率集合与子载波间隔集合的对应关系,确定服务小区对应的子载波间隔集合时,该预设的频率集合与子载波间隔集合的对应关系中可以包括X个子载波间隔集合,该X个子载波间隔集合中的任一子载波间隔集合可以包括至少一个子载波间隔,具体可以根据服务小区所对应的业务确定。其中,上述X可以为大于等于1的正整数,X的具体取值可以根据用户的需求确定。需要说明的是,上述X个子载波间隔集合中的第一子载波间隔集合至少包括一个子载波间隔不属于该X个子载波间隔集合中的第二子载波间隔集合,其中,这里所说的第一子载波间隔集合为上述X个子载波间隔集合中的任一子载波间隔集合,这里所说的第二子载波间隔集合为上述X个子载波间隔集中除上述第一子载波间隔集合之外的任一子载波间隔集合。可选的,上述预设的频率集合与子载波间隔集合的对应关系中还可以包括X个频率集合,该X个频率集合与上述X个子载波间隔集合可以一一对应,即每个频率集合对应一个子载波间隔集合。其中,该X个频率集合可以与通信系统所支持的频谱范围对应。

则在该表7所示的对应关系下,上述S202具体可以为:

可选的,上述预设的频率集合与子载波间隔集合的对应关系例如可以如表8所示:
表8
Figure PCTCN2017076619-appb-000009
则在该表8所示的对应关系下,上述S202具体可以为:
当服务小区对应的频率集合包括的频率均小于等于3GHz时,UE确定服务小区对应的子载波间隔集合包括15kHz子载波间隔和17.5kHz子载波间隔;
或,当服务小区对应的频率集合包括的频率均大于3GHz且小于等于6GHz时,UE确定服务小区对应的子载波间隔集合包括17.5kHz子载波间隔和35kHz子载波间隔;

或,当服务小区对应的频率集合包括的频率均大于80GHz时,UE确定服务小区对应的子载波间隔集合包括280kHz子载波间隔和560kHz子载波间隔。
在本实施例中,上述服务小区可以对应一个子载波间隔集合,该子载波间隔集合可以包括不同的子载波间隔,使得服务小区可以在不同场景下使用不同的子载波间隔,从而通过与场景更匹配的子载波间隔来提高通信系统的性能。例如:对于时延扩展大的场景,可以使用子载波间隔集合中的较小的子载波间隔,对于高速场景,可以使用子载波间隔集合中的较大的子载波间隔。以服务小区对应的频率集合包括的频率均小于等于6GHz,服务小区对应的子载波间隔集合包括15kHz子载波间隔和30kHz子载波间隔为例,则对于时延扩展大的场景,例如:时延扩展高达约5μs的场景,可以使用15kHz子载波间隔,对于高速场景,例如:高达500km/h的高速场景,可以使用30kHz子载波间隔。
在本实施例中,上述表3至表8所列举的频率集合和子载波间隔集合的对应关系,可以使每个子载波间隔集合中的每个子载波间隔与频谱均能够较好地匹配,从而在保证通信系统的性能的同时,能够最大限度的减少每个子载波间隔集合中的子载波间隔的个数。其中,上述频谱可以包括上述不同频率的集合。需要说明的是,上述表3至表8所示的子载波间隔集合可以适用于同一种业务的场景,例如只针对eMBB业务的场景。若服务小区同时支持多种业务,例如:同时支持eMBB业务和MTC业务等,则上述子载波间隔集合中的子载波间隔的数量可以根据所支持的业务的种类适当增加,具体可以根据业务的种类和用户的需求确定。
S203、UE根据服务小区对应的子载波间隔集合,确定服务小区的子载波间隔。
在本申请的一种实现方式中,上述UE可以根据服务小区对应的子载波间隔集合,检测服务小区的同步信号,并根据检测到的服务小区的同步信号,确定服务小区的子载波间隔。例如,UE可以根据服务小区对应的子载波间隔集合盲检服务小区的同步信号的方式,确定服务小区的子载波间隔。具体实施时,上述UE可以分别检测服务小区对应的子载波间隔集合中的每个子载波间隔对应的能量,其中,能量最大的子载波间隔即为服务小区的同步信号对应的子载波间隔,该同步信号对应的子载波间隔即为服务小区的子载波间隔。需要说明的是,上述UE检测子载波间隔对应的能量,具体可以参见现有技术,本申请对此不再赘述。
在采用这种方式确定服务小区的子载波间隔时,上述服务小区对应的子载波间隔集合可以包括小于等于两个子载波间隔(例如上述表3-表8所示的子载波集合),以减少UE盲检服务小区的同步信号的次数,提高UE检测服务小区的同步信号的成功率,缩短UE检测服务小区的同步信号的时间,也就是说缩短了UE接入服务小区的时间,提高了UE接入小区的成功率,从而提高了UE确定服务小区的子载波间隔的成功率。其中,本申请所涉及的服务小区的同步信号可以包括服务小区的主同步信号PSS和辅同步信号SSS 中的一个或多个。
在本申请的另一种实现方式中,上述UE还可以根据服务小区对应的子载波间隔集合,先确定服务小区的同步信号对应的子载波间隔和服务小区的广播信道对应的子载波间隔(这里所说的广播信道可以为传输主信息块(Master Information Block,MIB)的信道),从而根据确定的服务小区的同步信号对应的子载波间隔,检测服务小区的同步信号,并与服务小区同步,然后根据确定的服务小区的广播信道对应的子载波间隔,检测服务小区的主信息块,其中,该主信息块中可以包括子载波间隔指示信息,该子载波间隔指示信息可以向UE指示服务小区的子载波间隔,进而使得UE可以根据该子载波间隔指示信息,确定服务小区的子载波间隔。其中,本申请对子载波间隔指示的具体实现方式不进行限定,例如可以在主信息块中采用两个比特位作为子载波间隔指示,其中,不同的比特值可以对应不同的子载波间隔,以使得UE根据该比特值就可以确定服务小区的子载波间隔。
需要说明的是,上述UE检测服务小区的同步信号,以及,UE与服务小区同步,以及,UE检测服务小区的主信息块的具体实现方式,具体可以参见现有技术,本申请对此不再赘述。
在采用这种方式确定服务小区的子载波间隔时,上述服务小区的同步信号对应的子载波间隔和服务小区的广播信道对应的子载波间隔可以为服务小区对应的子载波间隔集合中的某一子载波间隔,可选的,上述服务小区的子载波间隔与服务小区的同步信号对应的子载波间隔和服务小区的广播信道对应的子载波间隔可以相同,也可以不同。在本申请的另一实现方式中,对应于该服务小区对应的子载波间隔集合中的每个子载波间隔,该服务小区的同步信号对应的子载波间隔和服务小区的广播信道对应的子载波间隔可以固定不变,例如:该服务小区的同步信号对应的子载波间隔和服务小区的广播信道对应的子载波间隔可以相同,且为服务小区对应的子载波间隔集合中最大的子载波间隔。示例性的,以包括15kHz子载波间隔和30kHz子载波间隔的子载波间隔集合为例,则该服务小区的同步信号对应的子载波间隔和服务小区的广播信道对应的子载波间隔可以均为30kHz。此时,由于对于服务小区对应的子载波间隔集合中的不同子载波间隔,都采用相同的子载波间隔发送同步信道和广播信道,从而使得UE不用盲检同步信号,就可以确定服务小区的子载波间隔,缩短了UE检测同步信号的时间,即缩短了UE与服务小区同步的时间,也就是说缩短了UE接入服务小区的时间,提高了UE检测服务小区的同步信号的成功率,也提高了UE接入小区的成功率,从而提高了UE确定服务小区的子载波间隔的成功率。
进一步地,上述服务小区的同步信号对应的循环前缀和服务小区的广播信道对应的循环前缀可以大于服务小区上的数据信道对应的循环前缀;例如,当上述服务小区上的数据信道对应的循环前缀约为2.38μs或约为4.76μs时,上述服务小区的同步信号对应的循环前缀约和上述服务小区的广播信道对应的循环前缀约可以为5.13μs。其中,这里所说的服务小区的同步信号对应的循环前缀和服务小区的广播信道对应的循环前缀,可以为传输同步信号的符号和传输广播信道的符号时对应的循环前缀,数据信道对应的循环前缀可以为传输数据的符号时对应的循环前缀。通过这种方式,可以扩大服务小区的同步信号和服务小区的广播信道的覆盖范围,提高服务小区的同步信号和服务小区的广播 信道的鲁棒性。
