RNP-1 – Ray-tracing simulation environment for RHS-based integrated communication and sensing networks

Ranplan Group AB (RNP), is seeking to appoint a high-calibre doctoral candidate to join the Marie Skłodowska-Curie Doctoral Network ‘joInt wireless commuNicaTion and sEnsinG by hologRaphic surfAce TranscEivers’ (INTEGRATE). The selected candidate will work under the supervision of Prof. Jie Zhang.

About the INTEGRATE project

As the standardization of 5G wireless networks progresses, the research community has started focusing on what 6G will be. Motivated by the need of ensuring high data-rates while at the same time saving spectrum a major technology that has been proposed for 6G is the integration of communication and sensing services in the same infrastructure. This enables wireless networks to perceive the surrounding environments triggering new services and leading to a more efficient use of resources. The INTEGRATE project focuses on the theoretical, algorithmic, and architectural foundations of integrated communication and sensing networks, developing the first open access network-level simulator for joint communication and sensing. To this end, a new implementation of wireless transceiver is proposed, which leverages the use of reconfigurable holographic surfaces and allows the integration of communication and sensing with remarkable performance while at the same time reducing the energy consumption.

Specifically, INTEGRATE will:

1. develop reconfigurable holographic surfaces (RHSs) capable of supporting joint communication and sensing tasks and that can be integrated in wireless transceivers with minimal cost and energy requirements;
2. Characterize the fundamental performance limits of integrated communication and sensing networks, developing an algorithmic framework and protocol suite to approach these limits;
3. Build the first open access software simulation platform for joint communication and sensing networks.

Research project: This project aims at developing new ray-tracing modules able to account for the presence of RHSs. New software routines will be developed in order to develop a ray-tracing software capable of supporting the near-field propagation in the presence of RHSs. To this end, the main challenge is that RHSs will have to be equipped with many electromagnetic units to provide the best communication and sensing performance, which poses a complexity issue for ray-tracing simulation, especially in large-scale networks. This challenge will be addressed by the use of Bayesian methods to predict wireless channels realizations, together with a multi-resolution approach. A fine resolution will be used to model the region of greater interest, e.g., locations of metasurfaces, while a lower resolution will be applied in those regions of the network in which fewer terminals are located. electromagnetic signal for the highest possible joint communication and sensing performance.

Objectives: Develop a new ray tracing module that accounts for the presence of RHS-based transceivers in large-scale networks.

PhD enrolment: The selected applicant will be enrolled into a Ph.D. program at University of Paris-Saclay, France, while working to the project.

Location: Riddargarten 18, Floor 1, S-114 51, Stockholm, Sweden.

Duration: Fixed-term (3 Years Full-time).

Secondment: RNP-1 will spend a research stay of 8 months at another partner of the INTEGRATE project. The planned secondment for RNP-1 is at University of Paris-Saclay, France.
