Beam failure detection and recovery for deactivated secondary cell group (SCG)

Embodiments include a method for a user equipment (UE) configured to communicate with a wireless network via a primary cell group (MCG) and a secondary cell group (SCG). Such a method includes entering an energy saving mode for the SCG in response to receiving a first command via the MCG or the SCG; while in an energy saving mode for the SCG and in an active mode for the MCG, beam fault detection (BFD) for the SCG is performed and one or more beam management operations for the SCG are avoided from being performed. In some embodiments, the UE may perform various operations after detecting a beam failure in the SCG while in an energy saving mode for the SCG. Other embodiments include supplemental methods for a network node configured to provide MCG or SCG, and a UE and network node configured to perform such methods. 实施例包括用于被配置为经由主小区组(MCG)和辅小区组(SCG)与无线网络通信的用户设备(UE)的方法。此类方法包括：响应于经由MCG或SCG接收第一命令而进入用于SCG的节能模式；当处于用于SCG的节能模式且处于用于MCG的激活模式时，执行用于SCG的波束故障检测(BFD)并避免执行用于SCG的一个或多个波束管理操作。在一些实施例中，UE可以在处于用于SCG的节能模式时检测到SCG中的波束
