AI Technical Summary

Technical Problem

In 5G wireless communication systems, determining available random access resources and configuring appropriate transmit power for random access preambles is challenging due to the use of high-frequency bands and multi-beam operations, leading to increased collision probability and overhead in informing transmit power.

Method used

A method and apparatus for determining initial active uplink bandwidth parts (UL BWP) and corresponding random access resources, including configuring and transmitting configuration information to user equipment (UE) for accurate random access procedures, and optimizing transmit power based on reference signal receiving power and path loss.

Benefits of technology

This approach reduces overhead, improves energy efficiency, prolongs terminal life, and enhances user experience by enabling reliable access for multiple users simultaneously, while minimizing power waste and collision probability.
