Holistic resource management and air interface abstraction models

Resource Management (RM) in fifth generation (5G) radio access network has been the subject of extensive study in recent years. An agile RM framework should encompass greatly-improved services from previous mobile network generations along with advanced new services meeting the challenging requirements, like massive data rate and ultra-low latency. The novel aspects of 5G system lies within co-existence of diverse legacy or new wireless technologies and air interfaces (AI) consuming shared resources of frequency, time, etc. This will lead to new use-cases, which should holistically be addressed by a comprehensive RM framework. In this paper we explore a number of these use cases, namely flexible services-based time scheduling, integration and abstraction of multiple AI variants (AIV) in a systematic way. RM for device-to-device communication and RM for internetwork collaboration have been shown as examples exploiting this model abstraction.
