Virtual multiple input multiple output (V-MIMO) systems employ a variety of scheduling algorithms to group multiple users and allocate the same set of physical resources to improve the spectral efficiency by exploiting the multiplexing capability in cellular uplink (UL) communication. This paper proposes an efficient dynamic scheduling algorithm for SC-FDMA-based UL network. It estimates the possible interference caused due to adding a new user to existing multiuser group and optimally selects users such that the interference level is within the limit for the receiver to perform flawless detection. A threshold for interference level based on the average SINR of the receiver ensures that users can be dynamically added to an existing group provided the total interference after adding new user is under the limit. Our extensive simulation results based on 3GPP LTE UL network shows that the proposed algorithm has much better performance than the existing random dynamic scheduling technique.
