下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的驻留方法及装置进行详细地说明。
首先对以下内容进行介绍:
Sidelink Relay机制:无线通信系统中的中继(Relay)技术,就是在基站与终端之间增加了一个或多个中继节点,负责对无线信号进行一次或者多次的转发,即无线信号要经过多跳才能到达终端。
无线中继技术不仅可用于扩展小区覆盖,弥补小区覆盖盲点,同时也可通过空间资源复用提升小区容量。对于室内覆盖,Relay技术也可起到克服穿透损耗,提升室内覆盖质量的作用。
以较简单的两跳中继为例,无线中继就是将一个基站-终端链路分割为基站-中继站和中继站-终端两个链路,从而有机会将一个质量较差的 链路替换为两个质量较好的链路,以获得更高的链路容量及更好的覆盖。
目前通信系统中已经支持的Relay为UE-to-Network relay,即Relay一端连接UE,一端连接网络侧。跟Relay连接的UE,叫做远端UE(Remote UE)。
图2是本申请实施例提供的中继场景的示意图;如图2所示,为UE-to-Network Relay机制的典型场景,Remote UE需要与网络侧传输数据,但由于覆盖不佳,找到Relay UE为其中转,其中Relay UE与基站之间是Uu接口,Relay UE和Remote UE之间是sidelink(PC5)接口。一般来说,Relay UE是开放的,可以为任何Remote UE服务。
图3是本申请实施例提供的驻留方法的流程示意图,如图2所示,该方法包括如下步骤:
步骤300,在第一终端确定同时满足第一条件和第二条件的情况下,第一终端确定驻留在与所述第一条件对应的直接链路或确定驻留在与所述第二条件对应的中继链路;
其中,所述第一条件包括小区选择条件或小区重选条件;所述第二条件包括中继选择条件或中继重选条件。
可选地,本申请实施例中的第一终端可以是中继场景下的远端终端。
可选地,本申请实施例给出一种SL relay场景的驻留方法,可以应用于中继场景下的远端终端。
可选地,当第一终端同时满足了中继选择/重选条件和小区选择/重选条件,可以确定接入该中继选择/重选条件对应的中继,或,该小区选择/重选条件对应的小区,从而明确第一终端应该执行中继选择/重选(即驻留在中继链路),还是执行小区选择/重选条件(即驻留在直接链路),确保Sidelink relay场景下的驻留在最佳链路下。
可选地,对于第一终端来说,如果合适的小区和合适的中继都可用,则第一终端可以基于本申请实施例提供的驻留方法来选择其中一个(或两者,仅对于L3中继)。
可选地,目标中继终端suitable relay UE可以称为合适的中继;
可选地,目标小区suitable cell可以称为合适的小区;
可选地,满足的中继选择/重选条件对应的中继可以是目标中继终端suitable relay UE,例如满足所有AS和继电器上层标准的中继;
可选地,满足第二条件可以是指满足目标中继终端suitable relay UE对应的中继选择/重选条件,即满足驻留在目标中继终端suitable relay UE对应的中继链路的条件;
可选地,满足的小区选择/重选条件对应的小区可以是目标小区suitable cell,例如,满足预定义的通信标准的小区;
可选地,满足第一条件可以是指满足目标小区suitable cell对应的小区选择/重选条件,即满足驻留在目标小区suitable cell对应的直连链路的条件。
可选地,本申请实施例适用于第一终端处于初始状态(比如刚开机的状态);此时第一终端可以同时满足小区选择条件和中继选择条件;
可选地,本申请实施例适用于第一终端处于初始状态(比如刚开机的状态),且还没有连接上任何中继终端;此时第一终端可以同时满足小区选择条件和中继选择条件;
