Abstract

本文公布一种系统消息的发送接收方法，包括：宏基站在宏小区的信道资源上发送微基站簇的系统消息，所述微基站簇包括两个以上属于所述宏基站的微基站。

Description

一种系统消息的发送接收方法及装置 技术领域
本申请涉及但不限于无线通信领域，尤指一种系统消息的发送接收方法及装置。
背景技术
第五代(5G，5th Generation)无线组网中，高频段微基站因其具有大带宽的优势，因此是一种重要的组网方式。高频段密集组网是5G无线组网的一个重要场景，由于其大带宽特性可为用户提供高速接入。但是，高频段比如毫米波波段的路径损耗很大，因此，基站覆盖相对来说就会比较小，比低频段(<3GHz)的覆盖小很多。
对于5G组网而言，一个合理的解决覆盖和容量的方案是用低频段宏基站来做覆盖，用高频段微基站来做容量。将一个低频段宏基站加上其周围一群高频段的微基站组成的一个簇(cluster)称为一个基站cluster。目前针对小区的系统广播消息是由每个小区本身使用其所具有的信道资源在其广播信道或者被调度的数据共享信道上发送的。但是在cluster组网下，如果系统消息的发送仍然按该方法发送，则每个高频段微基站都在自己的信道资源上周期性发送系统消息，由于微基站的数目是较大的，因此，这种发送方式至少具有两个缺点：1)浪费了微基站的信道资源；2)从节能的角度来讲，浪费了很多发射功率。

详述
下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
本发明实施例中，基站cluster由一个低频段的宏基站和多个高频段的微基站组成，宏基站的覆盖范围大于等于其所带的每个微基站的覆盖范围的和集，参照图1。
宏基站首先通过针对自身的系统消息，说明其自身是基站cluster中的宏基站。并且，宏基站为其所带的每个微基站(统称为微基站簇)，在宏小区的信道资源上代替微基站下发系统消息，这个系统消息是所有微基站的系统消息的和集，称作系统消息合集或者微基站簇的系统消息。微基站仅仅在自身的信道资源下发自身的基站ID，这个ID用于作为索引，以下简称为ID。
实际在组网时，微基站的很多配置有可能是相同的，对于这些相同的配置，宏基站在发送系统消息合集时，只需要发送一份配置数据，重复的配置数据无需做重复发送，终端(UE，User Equipment)在读取时，如果发现ID的数目大于配置数据的份数，则取距离ID索引最近的一份配置数据。
为便于说明，本发明实施例给出一种系统消息合集(也称为微基站簇的系统消息)的整体结构，见表1所示，每个系统消息内容见表2所示。

表2
对于基站cluster中的高频微基站，其系统消息不再需要下发带宽等系统配置信息，由系统消息合集的MIB负责发送，低频宏基站的MIB同时还发送对应微基站ID的频点信息、双工方式等关键信息，加速UE针对高频微基站的小区搜索过程。
引入基站cluster以后，UE小区搜索的过程如下：
1)UE对可能的低频段进行盲搜，搜索到低频段宏基站的系统消息。
2)UE读取宏基站的系统信息，确认其是基站簇归属的宏基站。
3)UE读取基站簇的系统消息，提取MIB中携带的频点信息，双工方式，小区识别号，带宽等关键信息。
4)UE按照第3步提取的频点信息，尝试与高频微基站同步，读取其基站ID，当UE与高频微基站取得同步后，维持与低频宏小区的联系，保证在和高频微基站的连接同时，仍能接收低频宏基站下发的系统消息以及其系统消息的改变。
5)UE按照ID，获取目标微基站的SIB1到SIB13等系统消息。
至此，UE获得cluster小区的所有信息。
图2为本发明实施例的系统消息的发送方法的流程示意图，如图2所示，所述系统消息的发送方法包括：
步骤201：宏基站在宏小区的信道资源上发送微基站簇的系统消息，所述微基站簇包括两个以上属于所述宏基站的微基站。
所述微基站簇的系统消息是指：所述微基站簇中每个微基站的系统消息的和集。
本发明实施例中，所述方法还包括：
宏基站通过所述宏基站的系统消息，指示所述宏基站是所述微基站簇的宏基站；
所述宏基站在宏小区的信道资源上发送所述宏基站的系统消息。
本发明实施例中，宏基站在宏小区的信道资源上发送微基站簇的系统消息时，对于每个微基站的相同的配置数据，发送一份所述配置数据。
本发明实施例中，所述宏基站在宏小区的信道资源上发送微基站簇的系统消息，包括：宏基站通过所述微基站簇的系统消息中的MIB发送每个微基站的系统配置信息、频点信息、双工方式和小区识别号，其中，所述小区识别号用于获得同步信号。
其中，系统配置信息可包括带宽信息。在传统机制中，频点信息、双工方式、小区识别号并不属于系统消息，不会通过系统消息发送给UE，因为UE可以通过物理层的搜索机制自动确定出来。本发明实施例中，不但通过系统消息发送系统配置信息，还发送微基站的频点信息、双工方式、小区识别 号等信息。
宏基站还可以通过微基站簇的系统消息中的SIB发送微基站的系统配置信息。图3为本发明实施例的系统消息的接收方法的流程示意图，如图3所示，所述系统消息的接收方法包括：
步骤301：终端接收宏基站在宏小区的信道资源上发送的微基站簇的系统消息，所述微基站簇包括两个以上属于所述宏基站的微基站。
本发明实施例中，所述微基站簇的系统消息是指：所述微基站簇中每个微基站的系统消息的和集。
本发明实施例中，所述方法还包括：
终端对低频段进行盲搜，搜索到宏基站的系统消息；
终端读取所述宏基站的系统消息，确定所述宏基站是微基站簇的宏基站。
本发明实施例中，所述方法还包括：
终端读取微基站簇的系统消息，从MIB中提取每个微基站的频点信息；
终端根据所述频点信息，与微基站进行同步，并获取所述微基站发送的基站标识(ID)；
终端根据所述微基站的ID，从所述微基站簇的系统消息中获取微基站的系统配置信息。
本发明实施例中，所述方法还包括：
当终端与所述微基站进行同步后，同时维持与所述宏基站的联系，其中，所述终端保持和所述微基站的连接的同时，接收所述宏基站发送的微基站簇的系统消息，以及接收所述宏基站发送的微基站簇的系统消息的改变信息，从而实时获得所述微基站最新的系统配置信息。
下面结合应用场景对本发明实施例的系统消息的发送接收方法作进一步描述。
应用场景1
如图4所示，cluster小区宏小区下挂4个高频段微小区，分别是小区 0,1,2,3。其频点分别是f0,f1,f2,f3，双工方式都是TDD，带宽，控制信道等相关配置都完全相同。微小区0和2有一个共同的4G邻区1、本cluster的宏小区0；微小区1和3有一个共同的4G邻区0、本cluster的宏小区0。其中4G邻区0和4G邻区1，以及cluster的宏小区0都使用相同的频率fL。
因此，对于这样一个典型的组网，系统消息合集仅仅包括MIB、SIB1、SIB2、SIB3、SIB5。参照如下表3：
Figure PCTCN2017091193-appb-000006
Figure PCTCN2017091193-appb-000007
表3
引入cluster以后，UE小区搜索的过程如下，
1)UE盲搜索低频段服务小区，并成功同步到cluster的低频宏小区0，读取其针对自身的系统消息，确认其属于cluster小区。
2)UE读取宏基站小区系统信息，确认其是cluster小区。
3)UE读取cluster小区的系统消息和集，提取MIB信息携带的频点f0,f1,f2,f3。
4)UE按照第3步提取的频点，尝试与高频微基站同步，读取其基站ID,假设UE位于微小区3的覆盖范围之内，则其成功同步到微小区3，提取微小区在其广播信道上发送的基站ID，对于本例子，ID为3。当UE与高频微基站取得同步后，继续维持与低频宏小区的联系，以获得其下发的系统消息，以及系统消息的改变。
5)UE按照ID，获取目标微基站的SIB1、SIB2、SIB3、SIB5等系统消 息。在提取SIB1、SIB2、SIB3时，由于3大于0，取靠近其最近的值即为基站0的系统消息作为本小区的系统消息。
至此，UE获得cluster小区下关于微小区3和低频宏小区的所有信息。
应用场景2
如图5所示，cluster小区宏小区下挂4个高频段微小区，分别是小区0,1,2,3。其频点分别是f0,f1,f2,f3，双工方式都是FDD，带宽，控制信道等相关配置各不相同。微小区0和2有一个共同的4G邻区1、本cluster的宏小区0，而且微小区0和2互为邻区；微小区1和3有一个共同的4G邻区0、本cluster的宏小区0。其中4G邻区0和4G邻区1，以及cluster的宏小区0都使用相同的频率fL。4个微小区的重选，接入等参数都各不相同。
因此，对于这样一个典型的组网，系统消息合集仅仅包括MIB、SIB1、SIB2、SIB3、SIB4、SIB5。如下表4所示：
