摘要

本文考虑一种采用非正交多址(NOMA)和小区不连续传输(Cell不连续传输)的基站,以降低其功耗,并研究了最优功率分配问题。我们首先证明了这个问题是凸的,并且只能使用单变量寻根算法来解决。然后,我们采用数值模拟来评估所提出的功率分配的性能。

Optimal Power Allocation for Minimizing the Energy Consumption of a NOMA Base Station with Cell DTx
In this paper, we consider a base station that jointly employs Non-Orthogonal Multiple Access (NOMA) and Cell Discontinuous Transmission (Cell DTx) in order to reduce its power consumption and we study the problem of optimal power allocation. We show first that this problem is convex and can be solved using only single variable root finding algorithms. Then, we employ numerical simulations in order to assess the performance of the proposed power allocation.
