In this paper, we maximize the parameterized energy efficiency (EEP) of a multi-channel fading communication link that simultaneously transmits data corresponding to delay-sensitive and delay-insensitive applications subject to a constraint on the minimum effective capacity (EC) of delay-sensitive traffic. EEP, in b/s/Hz, is defined as the difference between the spectral efficiency (SE) and the transmit...
In this paper, we consider the problem of energy-efficient resource and power allocation in the uplink of multiuser multi-channel Orthogonal Frequency Division Multiplexing (OFDM) based systems subject to constraints on user equipment (UE) transmit power. This problem is non-deterministic polynomial-time hard and an optimum solution for a system with U users and N resource units requires a complexity...
