Low-Power Wake-Up Signals for Reduced Main Receiver Usage

The receiver is divided into two distinct components: an LP-WUR designed for low-power wake-up signal reception and a full-featured main receiver (MR) for detailed control message decoding. The LP-WUR handles only the critical wake-up function with minimal power consumption, while the MR processes beam pair maintenance control messages when needed. This segmentation allows each component to be optimized for its specific function, resolving the contradiction between low power consumption and high decoding capability.

The LP-WUR acts as an intermediary that receives wake-up signals and triggers the MR to activate. This intermediary approach allows the system to maintain low power consumption during wake-up detection while enabling the full-featured MR to handle complex control message decoding only when necessary, thus resolving the contradiction between power savings and decoding reliability.

The system implements periodic wake-up cycles where the LP-WUR monitors for wake-up signals at low power intervals. The MR is activated periodically only when wake-up signals are detected, rather than remaining continuously on. This periodic activation pattern ensures communication reliability when needed while significantly reducing overall power consumption during sleep periods.

The LP-WUR performs preliminary wake-up detection before activating the full-featured MR. This preliminary action filters out unnecessary MR activations by first checking for wake-up signals at low power, thereby reducing overall power consumption while maintaining communication reliability through proper signal-triggered activation.
