Abstract:
Long Term Evolution (LTE) is a mobile network
that operates completely in packet domain. Due to the
variation of radio condition in LTE, the obtainable
bit rate for active users will vary. The two factors for
radio variation are fading and path-loss. By
analyzing the previous researches concerning with
packet scheduling of LTE network, in this paper, an
analytical model of the LTE radio scheduler is
proposed. This model is based on the stochastic
process to observe the system behavior
mathematically and takes the details of the
schedluler’s behavior taking into account given in a
state of the system, i.e. the number of the active users
and their distance from the base station. Instead
simulation result, the numerical result is shown. This
model mainly considers the path loss variation at
non-Guaranteed (nonGBR) bit rate such as FTP or HTTP.
