A novel cross-layer resource allocation scheme for multi-user, multi-service, MIMO-OFDMA systems

Abstract: International audienceThis paper presents a new cross-layer (PHY/MAC) resource allocation scheme based on Multiple Input Multiple Output (MIMO) and Orthogonal Frequency Division Multiple Access (OFDMA) system with a multi-service (MS) and a multiuser (MU) configuration. It is about a downlink transmission chain based on the IEEE 802.16m specifications, in which the available resources (power and bandwidth) are dynamically allocated according to the system parameters such as Channel State Information (CSI), spe… Show more

“…Several recent works have begun to consider OFDMA and MU-MIMO together [ 12 , 13 , 14 , 15 , 20 , 21 ]. Femanias et al examine subcarrier and power allocation as well as stream selection for downlink networks [ 12 ].…”

“…Hamda et al optimize the transmit power in an uplink cooperative MU-MIMO/OFDMA network by taking into account optimal relay selection [ 13 ]. In addition, many resource allocation methods have been proposed for various purposes, for example user-fairness [ 20 ], QoS (Quality of Service) [ 21 ], and PSNR (Peak Signal-to-Noise Ratio) for video communications [ 14 ]. Similar to our work, the recent seminal work by Kordbacheh et al models the interaction from the physical data rate to routing in the optimization for MU-MIMO/OFDMA networks, but a different approach is employed: greedy algorithm development from nonlinear optimization formulation [ 15 ].…”
