AI Technical Summary
Existing wireless communication systems, particularly in NR V2X, do not effectively implement DRX (Discontinuous Reception) to manage power consumption, especially for battery-based UEs in V2X use cases and public safety applications, leading to inefficient power usage.
Implementing DRX on the sidelink interface with mechanisms such as WUS (Wake-Up Signal) and GTS (Go-To-Sleep Signal) to manage UE power consumption, allowing UEs to switch between active and sleep modes based on reception mode configuration signals, including priority information and multiplexing with AGC (Automatic Gain Control) signals.
Reduces power consumption in battery-based UEs by enabling efficient power management through DRX, allowing UEs to conserve energy by switching to sleep modes when not actively transmitting or receiving data, thereby extending battery life in V2X and public safety applications.
