Coordination among base stations (BS) is a powerful approach for mitigating inter-cell interference and maximizing the sum spectral efficiency in cellular systems. In practice, however, coordination with a large number of BS may not be feasible due to excessive overheads associated with BS coordination, e.g., complexity, channel estimation and channel feedback. One practical solution for implementing multi-cell coordination is, therefore, to form a BS cluster so that a limited number of BS are coordinated to control intra-cluster interference with a reasonable amount of overhead.
IEEE GLOBECOM is one of two flagship conferences of the IEEE Communications Society, together with IEEE ICC. Each year the conference attracts about 3000 submitted scientific papers. A technical program committee of more than 1,500 experts provides more than 10,000 reviews, and from this a small fraction of the submitted papers are accepted for publication and presentation at the conference. The conference meets once a year in North America and attracts roughly 2000 leading scientists and researchers and industry leaders from all around the world.
