We consider the resource allocation problem in cellular networks which support Device-to-Device Communications (D2D) under the orthogonal resource sharing setting. We propose and analyze two resource allocation schemes that guarantee perfect access fairness among all users, regardless of whether they are cellular or D2D, while taking advantage of multi-user diversity and local D2D communications to...
In this paper, the problem of adaptive bit and power allocation for coded OFDM systems is considered. With emphasis on low feedback overhead and low complexity, we present a simple adaptive allocation technique, where data are transmitted only using the strongest subcarriers with uniform power and uniform constellation size. Due to the reduced number of used subcarriers, a fraction of coded bits are...
