Abstract :
In this paper, we consider a joint frequency-domain scheduling and user-pairing problem for virtual MIMO in SC-FDMA system, e.g., 3GPP-LTE. Due to the subcarrier adjacency constraint inherent to SC-FDMA, its complexity becomes unmanageable. We propose a greedy heuristic algorithm for PF scheduling to deal with the complexity in this joint problem. It has been shown that its performance can reach up to 90% of its upper bound.
