Description
相关申请的交叉引用
本申请主张在2020年7月24日在中国提交的中国专利申请号No.202010724743.9的优先权,其全部内容通过引用包含于此。
本公开涉及通信技术领域,尤其是指一种系统信息处理方法、获取方法、装置及终端。
相关技术中的无线通信采用蜂窝网络通信方式,即终端和网络侧设备通过Uu接口进行上下行数据或控制信息的传输。
直接通信是指邻近的终端可以在近距离范围内通过直接通信链路(也称为Sidelink或者PC5)进行数据传输的方式。Sidelink链路对应的无线接口称为直接通信接口(也称为Sidelink接口或者PC5接口)。
为了扩展网络覆盖,引入L2中继。L2中继本身可以是具有中继功能的终端。对于终端到网络中继(UE-to-Network Relay),L2中继和网络之间的接口使用Uu接口,和远端终端之间的接口使用直接通信接口。L2中继和网络之间的链路对远端终端而言可以称为回程链路(Backhaul link)。
长期演进(Long Term Evolution,LTE)系统中L2中继场景下,远端终端的系统信息获取方式如下:
网络可以配置中继终端是否允许向远端终端转发系统消息。如果中继终端允许向远端终端转发系统消息,则中继终端在Uu接口接收到系统消息后,可以将主系统信息块(Master Information Block,MIB),系统信息块1(SystemInformationBlock1,SIB1)以及直接通信相关SIB通过广播或者组播方式转发给远端终端。
对于第五代(5
th Generation,5G)以及未来的移动通信系统,除MIB或SIB1外,其他系统消息可以是按需(on-demand)发送的。因此相关技术中 的LTE L2中继系统的系统消息直接转发方式对于5G以及未来的中继通信系统并不适用。
