AI Technical Summary
Technical Problem
Wireless communication devices face challenges in reducing power consumption, particularly when using multiple receiver chains for MIMO communication, which increases power usage.
Method used
The solution involves dynamically determining the maximum number of MIMO layers based on communication parameters and inactivity timers, allowing the wireless device to adjust the number of active receiver chains accordingly, thereby opportunistically depowering unused chains to conserve power.
Benefits of technology
This approach effectively reduces power consumption by ensuring only the necessary receiver chains are active, thereby extending battery life and improving energy efficiency in wireless communication devices.
