Abstract

In this paper, we focus on the joint user grouping and the resource block (RB) allocation algorithm for LTE uplink virtual MIMO systems. Considering the user grouping and joint resource allocation, we construct a VMIMO transmission system model. Based on this system model, we formulate maximizes the sum of system’s capacity with the system constrains, which is a complexity optimization problem. Further, to reduce the computational complexity, especially in the case of large number of users and resources, an efficient branch search algorithm using revised simplex method based on bi-direction 0-1 pivot (SM_BD0-1P) is proposed. We evaluate the proposed joint resource allocation algorithms in LTE uplink scenarios and the results show that it achieves good tradeoff between performance and complexity and has better system throughput than the existing algorithms for LTE uplink virtual MIMO systems.
