Toward Dynamic Frequency Planning for Reliable Connectivity in Mobile 6G in-X Subnetworks

Within the research for the sixth generation of mobile networks, so-called in-X subnetworks (SNs) were proposed to support services with extreme performance requirements in geographically confined areas. To facilitate efficient spectrum usage and reliable connectivity within in-X SNs, adequate dynamic frequency planning methods for managing interference must be developed. This work provides background on in-X SNs and reviews related work on frequency planning and interference management. The problem of minimizing SN reconfigurations is identified as a key objective, while it is not addressed in the literature to date. Thus, the trade-off between minimizing subband usage and reducing SN reconfigurations is analyzed using both an already existing basic and a newly proposed advanced interference model. Preliminary results highlight how interference modeling and knowledge of future interference scenarios affect optimization outcomes, and future research directions toward dynamic frequency planning for in-X SNs in real 6G systems are discussed.     «
