Characterization of the missed spectrum-access opportunities under dynamic spectrum sharing

2016 8th International Conference on Communication Systems and Networks (COMSNETS), 2016
The radio frequency (RF) spectrum has been observed to be underutilized in the space, time, and frequency dimensions. To improve its utilization and meet growing demand, dynamic spectrum-sharing models are being investigated. In order to maximize the use of spectrum, we study how much of the spectrum can be potentially shared and how much is actually ...

Dynamic spectrum sharing for two-layer cellular networks

2011 IEEE 22nd International Symposium on Personal, Indoor and Mobile Radio Communications, 2011
Deploying femtocells faces a major challenge of causing downlink interference to the existing macrocell. This paper proposes an intelligent spectrum sharing mechanism for a two-layer cellular network, which comprises macrocells and femtocells. Because users are scheduled to access the spectrum in time-domain according to their channel conditions, the ...

Multi-tier exclusion zones for dynamic spectrum sharing

2015 IEEE International Conference on Communications (ICC), 2015
Reducing the size of exclusion zones (EZs) in spectrum sharing is vital for efficient utilization of fallow spectrum as well as for the economic viability of spectrum sharing itself. In this paper, we explore two approaches for reducing the size of EZs. We show that multi-tiered EZs can be used to improve spectrum utilization efficiency by implementing
