We consider spectrum sharing between a limited set of operators having similar rights for accessing spectrum. A coordination protocol acting on the level of the RAN is designed. The protocol is non-cooperative, but assumes an agreement to a set of negotiation rules. The signaling overhead is low, and knowledge of a competitor’s channel state information is not assumed. No monetary transactions are...
A cloud radio access network (Cloud-RAN) is a new cellular technology that brings baseband processing units for a set of base stations into a central server retaining only the radio front-ends at the cell sites. This new architecture opens up opportunities for algorithms that require centralized processing. However, efficient implementation of the algorithms presents a number of challenges the most...
In this paper, we study the strategic coexistence of macro and pico cells and investigate a utility based resource allocation technique for heterogeneous networks. Aiming at finding an objective driven allocation of resources, we focus on time domain inter-cell interference coordination (ICIC) techniques. Macro and pico cells optimally select their almost blank subframe (ABS) muting rate and cell...
