Recently, a lot of research effort has been spent on cross-layer system design. It has been
shown that cross-layer mechanisms (ie, policies) potentially provide significant performance …

Adaptive orthogonal frequency division multiple access (OFDMA) has recently been
recognized as a promising technique for providing high spectral efficiency in future …

For wireless systems with adaptive modulation and/or scheduling, feedback of channel
quality information is often necessary. It has been questioned whether the increased system …

In this paper we review contributions regarding dynamic, ie, channel-state adaptive
schemes for OFDM systems. As the wireless broadband channel is frequency-selective, the …

Device-to-Device (D2D) communications have recently attracted researchers, attention
because of their numerous applications in industry verticals. It enables communications …

Although the voice over Internet protocol (VoIP) service is expected to be widely supported
in wireless mobile networks, the feasibility and capacity of the protocol have not previously …

Within the last decade, the orthogonal frequency-division multiplexing (OFDM) transmission
scheme has become part of several standards for wireless systems. Today, OFDM is even a …

Flexible employment of frame configuration in light of the Doppler frequency change is
proposed. According to the present invention, frame configuration for a predetermined …

In this paper, the author studies the sum throughput maximization with proportional fair
scheduling (PFS) for downlink orthogonal frequency division multiple access (OFDMA) …

In this paper, we study the sum throughput maximization with access proportional fairness
(APF) for downlink orthogonal frequency-division multiple access (OFDMA) channels. We …
