Cross Layer Resource Allocation For Multi User Communication Systems

Satisfaction of different QoS demands for various broadband services in wireless networks requires that multi-user packet scheduling intelligently use both channel state information (CSI) and queue state information (QSI). A combination of queue-channel-aware scheduling and power/rate allocation on each transmit dimension is known as "cross-layer resource allocation". This thesis investigates various aspects of cross-layer resource allocation to illustrate its important role in multi-user communication systems. Of particular interest are downlink and uplink wireless systems that use orthogonal frequency division multiplexing (OFDM) modulation and multi-input multi-output (MIMO) transmission with multiple antennas.
