Both approaches show significant performance gains in the severe cell border area. With the soft intercell interference cancellation scheme, it is possible to reach the single-user bound. ...
The handling of intercell interference at the cell border area is a strong demand in future communication systems to guarantee efficient use of the available bandwidth. ...
As an upper bound of the system, the performance with no ICIC is illustrated. The lower bound is represented by the single-user performance without any intercell interference. ...

Fifth-generation (5G) mobile networks aim to be qualified as the core connectivity infrastructures to address connected automated mobility (CAM), both from a technological and from a business perspective ...
However, cross-border contexts imply paramount communication challenges, such as seamless roaming, not addressed by current technology. ...
In Ethernet networks, where there is no roaming at all, this is addressed by applying time-sensitive networking standards that ensure bounded latency instead of a best-effort approach. ...

Cognitive radio networks significantly improve spectrum utilization efficiency by allowing unlicensed users to opportunistically access the unused licensed spectrum. ...
One of the key challenges is to determine how to properly assign the unused spectrum slots without impacting the licensed users and if necessary, move the existing users to different spectrum bands. ...
If the network has a bounded response time (or a threshold on delay) and the demand is high, these approaches will not be able to compute a solution within the time limit. ...
