In existing cell-free non-orthogonal multiple access (NOMA) networks, each user equipment (UE) receives desired signals from a group of access points (APs) simultaneously, however, the UE belongs to only a single NOMA cluster. This prevents exploiting the potential benefits of having clusters wit...
In order to ensure the real-time requirement of user equipment, a markov decision process (MDP) model is constructed by quantifying resources in access points (APs) and user equipments (UEs). On this basis, we propose a Deep Q-Network (DQN) based dynamic uplink power control algorithm to ...

We present a simple NOMA-aided CF-mMIMO system model that considers single-antenna APs and single-antenna user equipment (UE) with a time-division duplex (TDD) transmission protocol. We further analyze the various works that concern NOMA with CF-mMIMO, to highlight the challenges and ...
P1 = aPs, Sensors 2021, 21, 5720 4 of 18 P2 = (1 − a)Ps, where Ps is the BS transmit power and a is the BS power allocation factor. In the proposed network model, the channel power gain of the BS − U2 link is less than that of the BS − U1,k link, so the BS ...
