“…Coordination mechanisms have a large impact on the gains that spectrum sharing can achieve, and are intertwined with the supporting architectural solutions [3], [5], [8], [10]- [13]. The early work by Mihovska et al proposed an approach for both intra-and inter-operator coordination scenarios and concluded that operators can advantageously pool spectrum resources when network loads are temporarily uneven among the cooperating operators [10]. Ghadikolaei et al [8] showed that the large antenna setting can reduce the need for interoperator coordination.…”

“…for urban and suburban scenarios, outside the high rise core, where the buildings are of nearly uniform height. In (1), R is the separation between the base station (BS) or eNB and the UE, f is the carrier frequency, and D hb is the BS antenna height, measured from the average rooftop level. Considering two carrier frequencies, 800 MHz and 2 GHz, D hb = 15 m and a UE antenna of 1.5 m, one considers the following path loss model:…”

“…Most of the spectrum bands suitable for terrestrial wireless communication have already been allocated by the regulatory agencies to existing licensees, which has led to a spectrum scarcity problem. Dynamic spectrum access (DSA) techniques are promising to enable spectrum aggregation (SA) with intra-operator multiband scheduling [1]. DSA takes advantage of the non-uniform geographic and temporal distribution of traffic and interferers within a network, improving the efficiency of idle and underutilised radio frequency bands through sharing, coexistence and aggregation.…”
