Welcome to Radio Resource Management for 5G New Radio
Description:
In this PhD course we will present the technology enablers for multi-service radio resource
management (RRM) in the 5G new radio (NR) as standardized by 3GPP. The system design
of NR will be presented, high-lighting the large degree of flexibility and options designing
state-of-the-art RRM algorithms to meet the future demands for managing complex multiservice
scenarios with highly diverse quality-of-service requirements. The course will cover
the following aspects:
- Overview of QoS service architecture for the 5G NR
- Review of the user- and control-plane protocol stack in radio part of the NR (i.e. SDAP,
- PDCP, MAC, PHY, RRC)
- Options for centralized and distributed network implementations of the NR
- Agile multi-service scheduling, including MAC scheduling and its interaction with QoE manager; this part will cover the many new scheduling options for NR and how to best explore those, given the flexible frame structure
- Non-scheduled options, also known as grant-free access
- Optimizations specifically tailored for enhanced mobile broadband and ultra-reliable low latency communications
- Specific RRM enablers to have NR operate with advanced beamforming and massive MIMO
- Options for service specific link adaptation and Hybrid Automatic Repeat reQuest (HARQ) enhancements
Specific aspects will be covered by self-study, but discussed in connection with the course,
e.g. multi-node connectivity options and enhanced mobility management. The course will
present the rationales for the various design choices made by 3GPP for the NR, highlight
differences as compared to LTE, and the design choices that are left open from the 3GPP
NR specifications. In fact, the former still leaves lots of design choices open, and present a
number of new challenging research problems that remains to be addressed. To this end,
the course gives an outlook of what is coming in the next 3GPP releases of NR.
Prerequisites:
It is expected that participants in this course are familiar with the basics of the 5G NR
physical layer design as well as principles of the LTE system design.
Learning objectives:
- General update on 5G standardisation
- Identification of open research areas/topics
- Specific radio resource management techniques for advanced physical layer and wireless systems with a high degree of (system) complexity
Teaching methods:
Lectures, exercises and short presentations/updates from participants (radio resource management
problem related to own research area, discussions based on self-study)
Criteria for assessment:
Active participation, with registration, and contribution to discussions, presentations and exercises.
Key literature:
Main literature will comprise overview papers/articles, excerpts from standardisation, and a
compendium of the course presentation material.

Important information concerning PhD courses We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 5,000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately three months before start. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.
