AI Technical Summary
Terminal devices suffer from ineffective power consumption when detecting network-side signaling, especially when detecting paging messages in idle state and control channels in connected state, leading to unnecessary energy consumption.
By receiving the first signal on the first frequency domain resources and determining the second frequency domain resources for receiving the second signal based on the beam scanning of the first signal, narrow beam scanning and frequency division multiplexing are adopted to reduce the receiving power consumption of the terminal equipment.
This reduces the receiving power consumption of terminal devices in continuous monitoring mode, improves receiving performance, and facilitates subsequent communication such as random access.
