Title
Average Downlink Rate In Ultra-Dense Networks
Abstract
In this paper, we study the average downlink rate in Ultra-Dense Networks (UDNs) considering the idle mode capability of the base stations (BSs). Wireless networks are densified by deploying a surplus of small cells in order to provide uniform coverage and high capacity. Consequently, the density of the small cells outpaces that of the active users in UDNs. Idle mode capability permits the idle BSs, due to lack of connected users, to turn off in order to mitigate their interference. We employ tools from stochastic geometry to compute the average downlink rate considering a general fading channel in both signal and interference links. In UDN, the likelihood of Line-of-Sight (LOS) transmission in some scenarios is high due to the closeness of the serving cells to the associated users. This propagation environment requires the consideration of Rician channel rather than Rayleigh channel in this context. The analytical results show a high degree of accuracy which is confirmed by extensive simulations in different combinations of the system parameters including small cell density, active users density, path loss exponent, and fading channels. Moreover, we simulate the impact of the association of a user to many BSs on the average downlink rate.
