Resource allocation for maximizing outage throughput in OFDMA systems with finite-rate feedback
Previous works on orthogonal frequency division multiple access (OFDMA) systems with quantized channel state information (CSI) were mainly based on suboptimal quantization methods. In this paper, we consider the performance limit of OFDMA systems with quantized CSI over independent Rayleigh fading channels using the rate-distortion theory. First, we establish a lower bound on the capacity of th...

متن کاملAnalysis of OFDMA resource allocation with limited feedback
Radio link adaptation, multiple antenna techniques, relaying methods and dynamic radio resource assignment are among the key methods used to improve the performance of wireless communication networks. Opportunistic resource block (RB) allocation in downlink orthogonal frequency division multiple access (OFDMA) with limited feedback is considered. The spectral efficiency analysis of multiuser OF...

متن کاملA Dual-based Method for Resource Allocation in OFDMA-SDMA Systems with Minimum Rate Constraints
We consider multi-antenna base stations using orthogonal frequency-division multiple access (OFDMA) and space division multiple access (SDMA) techniques to serve single antenna users, where some of those users have minimum rate requirements and must be served in the current time slot (real time users), while others do not have strict timing constraints (non real time users) and are served on a ...
