Title
Energy Efficient Pilot And Data Power Allocation In Multi-Cell Multi-User Massive Mimo Communication Systems
Abstract
In this paper, we propose a joint pilot and data power allocation scheme aiming to improve the energy efficiency of time division duplexing (TDD) massive multi-user multiple-input multiple-output (MU-MIMO) communication systems for both uplink and downlink transmission. The proposed scheme uses a maximum-ratio combining (MRC) detector in the uplink together with a maximum-ratio transmission (MRT) precoder in the downlink. By using minimum mean square error (MMSE) channel estimation, the total uplink and downlink transmit power is minimized under per-user signal to interference-plus-noise ratio (SINR) requirement and per-user power consumption constraints. Lower bounds of the average SINR are derived and used in the power allocation algorithm in order to simplify the optimization problem. The tightness of the derived SINR lower bounds and the advantage of the proposed power saving scheme as compared to equal power allocation among all users are validated by computer simulation.
