本申请主张在2017年5月4日在中国提交的中国专利申请No.201710308576.8的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种物理广播信道的传输方法及装置。
背景技术
在第四代移动通信技术长期演进(4th-Generation Long Term Evolution，4G LTE)系统中，物理广播信道(Physical Broadcast Channel，PBCH)用于传递小区重要信息，包括系统带宽、系统帧号等。终端通过PBCH可了解系统基本信息，继而为接入网络做准备。LTE中的主信息块(Master Information Block，MIB)信息通过PBCH进行传输。同时，PBCH是一种非调度、固定周期、固定大小、固定传输模式的物理信道。
在5G新空口(New Radio，NR)研究中，PBCH仍是重要课题方向。5G NR系统增加了高频传输，这导致NR PBCH与传统LTE PBCH会有不同。NR PBCH同样用来传递小区重要且基本信息，除包括系统带宽、系统帧号外，还可能包括波束扫描等相关信息。截止RAN1#88bis会议结束，已同意NR PBCH将占用40～100比特(bit)内容，且占用频带288子载波，2个时域符号，同时，也同意PBCH将传输剩余最小系统信息的调度信息的相关配置信息，将寻呼信息的指示信息也在PBCH中传输作为备选。因此，这导致NR PBCH承载比特相比于LTE大大增加。同时，不同信息所需要承载的资源及周期也会有很大不同。
但由于当前PBCH是一种非调度、固定周期、固定大小、固定传输模式的物理信道，因此，对于多场景部署及应用大规模多天线技术的5G NR系统来说，当前PBCH无法满足多场景兼容、配置灵活、时延等需求。

附图说明
为了更清楚地说明本公开实施例的技术方案，下面将对本公开实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
首先指出的是，本公开实施例的物理广播信道的传输方法，通过非调度、包括具有不同周期和/或不同负载大小的多个PBCH分段的PBCH，能够满足不同信息的承载需求，相比于通过相关技术中的固定周期、固定大小、固定传输模式的PBCH传输PBCH数据，可具有兼容多场景、配置灵活、资源利用率高、降低时延等优点。
参见图1所示，本公开实施例提供一种物理广播信道的传输方法，应用于基站，包括步骤101至步骤103，详述如下。
步骤101：获取PBCH数据。
其中，PBCH数据可以为最小系统信息，也可以为承载内容和周期都比 最小系统信息的承载内容和周期大的系统信息，例如剩余最小系统信息和/或寻呼信息，也可以为最小系统信息、剩余最小系统信息和寻呼信息，本公开不对其进行限制。具体地，最小系统信息通常为最频繁的系统信息，例如包括MIB信息等。剩余最小系统信息包括但不限于该剩余最小系统信息的调度信息的资源指示信息，寻呼信息包括但不限于寻呼指示信息。
步骤102：确定PBCH中与所述PBCH数据对应的PBCH分段。
其中，本公开实施例中的PBCH为一种非调度、包括具有不同周期和/或不同负载大小的多个PBCH分段的物理信道，即本公开实施例的PBCH包括具有不同周期和/或不同负载大小的多个PBCH分段。在确定与PBCH数据对应的PBCH分段时，可基于预先约定或协议约定，确定与PBCH数据对应的PBCH分段。而PBCH分段也可称为PBCH子集。
例如，参见图2所示，本公开一个具体实例的NR PBCH可包括三个PBCH分段，分别为NR-PBCH subset(子集)1、NR-PBCH subset2和NR-PBCH subset3，其中，NR-PBCH subset1的承载内容大小为B1，周期为T1，NR-PBCH subset2的承载内容大小为B2，周期为T2，NR-PBCH subset3的承载内容大小为B3，周期为T3，且B1＜B2＜B3，T1＜T2＜T3。
步骤103：通过与所述PBCH数据对应的PBCH分段，传输所述PBCH数据。
其中，在确定与PBCH数据对应的PBCH分段后，就可通过与PBCH数据对应的PBCH分段，传输PBCH数据。此处的PBCH分段依据对应PBCH数据的不同，可以为一个PBCH分段，也可以为多个PBCH分段。
本公开实施例的物理广播信道的传输方法，通过PBCH中与PBCH数据对应的PBCH分段，传输PBCH数据，PBCH包括具有不同周期和/或不同负载大小的多个PBCH分段，能够满足不同信息的承载需求，相比于通过相关技术中的固定周期、固定大小、固定传输模式的PBCH传输PBCH数据，可具有兼容多场景、配置灵活、资源利用率高、降低时延等优点。
本公开实施例中，当PBCH数据为最小系统信息时，确定PBCH中与PBCH数据对应的PBCH分段可具体为：
确定与最小系统信息对应的PBCH分段为，多个PBCH分段中的周期最 小和/或承载内容最小的PBCH分段。
例如，在图2所示的NR PBCH的前提下，可确定与最小系统信息对应的PBCH分段为NR-PBCH subset1。
这样，基站在确定与最小系统信息对应的PBCH分段后，就可通过多个PBCH分段中的周期最小和/或承载内容最小的PBCH分段，传输最小系统信息，使得终端频繁快速接收最小系统信息，满足终端需求，且相比于相关技术中的固定周期的PBCH，可借助将传输最小系统信息的PBCH分段的周期设置较小，从而达到时延降低的效果。
进一步的，针对仅预先约定或协议约定，多个PBCH分段中的周期最小和/或承载内容最小的PBCH分段的配置信息的情况，为了使终端了解多个PBCH分段中的除周期最小和/或承载内容最小的PBCH分段外的其他PBCH分段的配置信息，本公开实施例的传输方法还可包括：
通过周期最小和/或承载内容最小的PBCH分段，传输多个PBCH分段中，除周期最小和/或承载内容最小的PBCH分段外的其他PBCH分段的配置信息。
其中，其他PBCH分段的配置信息例如为其他PBCH分段的周期大小、承载内容大小等。这样，终端了解其他PBCH分段的配置信息后，可有利于终端准确接收PBCH数据。
本公开实施例中，当PBCH数据为剩余最小系统信息和/或寻呼信息时，确定PBCH中与PBCH数据对应的PBCH分段可具体为：
确定与剩余最小系统信息和/或寻呼信息对应的PBCH分段为，多个PBCH分段中的除周期最小和/或承载内容最小的PBCH分段外的其他PBCH分段中的至少一个PBCH分段。
例如，在图2所示的NR PBCH的前提下，可确定与剩余最小系统信息和/或寻呼信息对应的PBCH分段为NR-PBCH subset2和/或NR-PBCH subset3。
这样，通过周期较大且承载内容较大的PBCH分段传输剩余最小系统信息和/或寻呼信息，既可保证完整传输剩余最小系统信息和/或寻呼信息，又可避免频繁传输，节省系统资源，提高资源利用率。
此外，相比于相关技术中的固定传输模式的PBCH，本公开实施例的PBCH分段，即一个PBCH分段或多个PBCH分段，在一个同步信号块(Synchronization Signal Block，SS Block)内，可与主同步信号和/或辅同步信号采用频分复用、时分复用和/或码分复用方式进行传输。也就是说，本公开实施例中，通过与PBCH数据对应的PBCH分段，传输PBCH数据可具体为：
通过与PBCH数据对应的PBCH分段，在一个同步信号块内与主同步信号和/或辅同步信号采用频分复用、时分复用和/或码分复用方式，传输PBCH数据。
下面，结合图3至图4(b)对本公开另一个具体实例的物理广播信道的传输过程进行说明。
参见图3所示，本公开该另一个具体实例的NR PBCH包括两个PBCH分段，分别为NR-PBCH和NR-SPBCH(NR-Secondary PBCH,NR-辅PBCH)，NR-PBCH和NR-SPBCH均为非调度传输信道，并且，NR-PBCH周期与SS block周期相同，承载内容大小固定为80比特，NR-SPBCH周期为SS block周期的三倍，承载内容大小固定为150比特，这样，基站在传输NR MIB信息时，可通过NR-PBCH进行传输，而在传输剩余最小系统信息的调度信息的资源指示信息和寻呼指示信息时，可通过NR-SPBCH进行传输。对应的，终端在接收NR MIB信息时，可通过NR-PBCH进行接收，而在接收剩余最小系统信息的调度信息的资源指示信息和寻呼指示信息时，可通过NR-SPBCH进行接收。
进一步的，参见图4(a)所示，NR-PBCH在传输时，在SS block1内可与主同步信号(Primary Synchronization Signal，PSS)和辅同步信号(Secondary Synchronization Signal，SSS)采用时分复用方式，NR-SPBCH在传输时，在SS block1内可与PSS和SSS采用频分复用方式，具体地，NR-SPBCH分成两段，分别为NR-SPBCH-1和NR-SPBCH-2，且NR-SPBCH-1与PSS频分复用，NR-SPBCH-2与SSS频分复用。
另外，参见图4(b)所示，NR-PBCH和NR-SPBCH在传输时，在SS block1内也可与PSS和SSS采用时分复用方式。
上述实施例对本公开的基站侧的物理广播信道的传输方法进行了说明，下面将结合实施例和附图对本公开的对应终端侧的物理广播信道的传输方法进行说明。
参见图5所示，本公开实施例还提供一种物理广播信道的传输方法，应用于终端，包括步骤501，详述如下。
步骤501：通过PBCH中的PBCH分段，接收与所述PBCH分段对应的PBCH数据。
其中，PBCH包括具有不同周期和/或不同负载大小的多个PBCH分段。PBCH数据可以为最小系统信息，也可以为承载内容和周期都比最小系统信息的承载内容和周期大的系统信息，例如剩余最小系统信息和/或寻呼信息，也可以为最小系统信息、剩余最小系统信息和寻呼信息，本公开不对其进行限制。具体地，最小系统信息通常为最频繁的系统信息，例如包括MIB信息等。剩余最小系统信息包括但不限于该剩余最小系统信息的调度信息的资源指示信息，寻呼信息包括但不限于寻呼指示信息。

进一步的，本公开实施例中，所述传输方法还包括：
