Resource allocation is a challenging issue in multiuser wireless systems. Since users are
not all in the same conditions and do not achieve the same performance given the same …

Enabling completely universal coverage, the space-ground communication system
integration is one of the most important aspects in the fifth generation (5G) or even the next …

We consider the scheduling problem in downlink wireless networks with heterogeneous,
Markov-modulated, ON/OFF channels. It is well-known that the performance of scheduling …

A resource allocation problem for a cognitive radio base station (CR-BS) communicating
with multiple CR mobile stations (MSs) is considered in the downlink, which relies on …

In this paper, we consider the power minimization problem of joint physical resource block
(PRB) assignment and transmit power allocation under specified delay and reliability …

In this paper, we study resource scheduling in a relay-assisted cognitive radio network with
the orthogonal frequency division multiple access (OFDMA) scheme adopted to cope with …

This paper studies the achievable rate and power allocation to improve the uplink (UL)
spectrum efficiency in a Long-Term Evolution Advanced (LTE-A) cooperative cellular …

In wireless fading channels, multi-user scheduling has the potential to boost the spectral
efficiency by exploiting diversity gains. In this regard, proportional fair (PF) scheduling …

Multiple-input—multiple-output (MIMO) orthogonal frequency-division multiple access
(OFDMA) has been selected as the core physical-layer access scheme for the downlink of …

This paper studies optimal transmission over wireless channels with imperfect channel state
information available at the transmitter side in the context of point-to-point channels …
