Tiivistelmä

Unexpected fluctuations in radio resource demands of active sessions in millimeter-wave (mmWave) systems caused by dynamic blockage of the line-of-sight path may lead to accidental session drops. Existing solutions addressing this problem incorporate multi-connectivity operation that reroutes an ongoing session to another mmWave access point (AP) nearby. We introduce and analyze an alternative approach for improving session continuity based on the concept of bandwidth reservation. We develop an analytical model for the mmWave system that employs the proposed technique and quantify its benefits and drawbacks. We show that even a small fraction of reserved bandwidth may significantly improve session continuity.
