In this paper, we propose a novel and efficient OS scheme with partial CQRI feedback. The average system capacity of the proposed OS scheme with partial CQRI feedback is analyzed as well as those of the conventional OS schemes with full and partial CQI feedbacks. Analysis and simulation results show that the proposed scheme improves system performance in terms of the average system capacity, especially when the amount of feedback per user is restricted to be small. It is shown that when the number of users is 100, the proposed scheme achieves 90% capacity of the full CQI feedback scheme, requiring only 4% and 60% feedback rate of the conventional full and partial CQI feedback schemes, respectively.
