no code implementations • 27 Sep 2023 • Emanuele Peschiera, Xavier Mestre, François Rottenberg

We study cell-free massive multiple-input multiple-output precoders that minimize the power consumed by the power amplifiers subject to per-user per-subcarrier rate constraints.

no code implementations • 4 Apr 2023 • Emanuele Peschiera, François Rottenberg

When considering the overall BS power consumption and a large number of subcarriers, we show that significant savings are achievable in the low-load regime by using a subset of the BS antennas.
