Abstract

Wireless communications systems may employ shared control resource set (CORESET) configurations for control information monitoring by a user equipment (UE) in an inactive state (e.g., for wake-up signal (WUS) monitoring) and for control information monitoring by a UE in an active state (e.g., for physical downlink control channel (PDCCH) monitoring). Further, a shared CORESET configuration may support one or more dynamic or variable configuration parameters, such that a shared CORESET configuration may be partially modified to optimize control information monitoring in different scenarios (e.g., to optimize WUS monitoring and PDCCH monitoring when using a shared CORESET configuration). For example, a CORESET configuration may include one or more static configuration parameters (e.g., a time resource, a frequency resource, a transmission configuration indicator (TCI) state, etc.) and one or more dynamic configuration parameters (e.g., an interleaving pattern, a precoding granularity, a time duration, a scrambling identification, etc.).
