Area of Science:

• Wireless Communication Engineering
• Telecommunications Technology
• Signal Processing

Background:

• 5G mobile networks utilize the millimeter-wave (mmWave) spectrum for high capacity.
• Directional beamforming is crucial for mmWave, but challenges conventional power-saving techniques like Idle Discontinuous Reception (IDRX).
• Current directional paging in mmWave networks leads to substantial resource overhead due to multi-beam transmissions.

Purpose of the Study:

• To propose a novel paging mechanism for directional air interfaces in mmWave-enabled 5G communications.
• To address the increased paging resource overheads associated with directional beam-based transmissions.
• To enhance power savings for devices operating in IDRX mode within mmWave networks.

Main Methods:

• Development of a Partitioned UE ID-based Directional Paging (PIDP) mechanism.
• Numerical analysis to evaluate the performance of the proposed PIDP mechanism.
• Comparison of PIDP with conventional directional paging strategies.

Main Results:

• The PIDP mechanism effectively reduces paging resource overheads in mmWave networks.
• The proposed method achieves a 15% gain in power savings compared to existing directional paging methods.
• PIDP demonstrates improved energy efficiency for devices utilizing directional beams.

Conclusions:

• The PIDP mechanism offers a viable solution for optimizing paging in directional mmWave 5G systems.
• Implementing PIDP can significantly reduce network resource consumption and improve device battery life.
