ABSTRACT
Abstract:
Power control is used in cellular communications systems to reduce power consumption and satisfy as many users as possible by managing the mutual interference between users.
In signal to interference plus noise ratio (SINR) tracking power control schemes, all users are required to adjust their power levels each iteration, which is inefficient.
In this seminar, a prioritized and selective uplink power control scheme is discussed.
Priority user (PU) requirements are satisfied first, and then as many normal users (NUs) as possible are satisfied with their target SINRs.
In addition, if an NU is currently satisfied with their target SINR, they are not required to update their transmit power level.
Conversely, NUs who are not satisfied update their power levels.
Simulation results are presented which show that the proposed scheme outperforms dynamic target SINR tracking power control
(DTPC) and variable target SINR tracking power control (VTPC) in terms of power consumption and efficiency.
In addition, the proposed scheme is better than target SINR tracking power control (TPC) and opportunistic power control (OPC) as the number of users increases.
