TL;DR: In this paper, the sum-rate maximization problem was studied for wireless networks that use downlink rate splitting multiple access (RSMA), where the base station (BS) divides the messages that can be transmitted to its users into a private part and a common part.

TL;DR: An analytical model is employed to solve a cross-layer optimization problem in IEEE 802.11 wireless local area networks using M/M/1 queuing model, and subsequently an adaptive MAC retry limit scheme is studied.

TL;DR: A low-complicity and accurate model is found to solve the problem of optimizing MAC-layer transmission of real-time video over wireless local area networks (WLANs) using cross-layer techniques and can be effectively invoked for analyzing adaptive retry-limit algorithms.

TL;DR: Investigation of the impact of power and continuous-rate adaptation using variable-power M-ary quadrature amplitude modulation (MQAM) on spectral efficiency of orthogonal frequency-division multiplexing (OFDM) systems subject to carrier frequency offset (CFO) in Rayleigh fading channels with perfect and imperfect channel information at the transmitter suggests adaptive modulation can improve the spectral efficiency.

TL;DR: Numerical results affirm that the secondary link of spectrum sharing system combining ARQ with adaptive modulation and coding (AMC) achieves significant gain in ASE depending on the maximum number of retransmissions initiated by the ARQ protocol.
