A real time radio link monitoring using CSI

Abstract

In this paper, a real time radio link monitoring scheme for wireless communication applications is proposed. It can be used as a part of the radio resource management for the efficient radio link control in wireless communication systems. The proposed method is based on the use of the channel state information transmitted or generated by mobile terminals and base stations. In contrast to the existing radio link monitoring schemes, the proposed method can provide very fast responses to the channel variations so that it is appropriate for the real time operations. In addition, the proposed scheme is computationally efficient to implement.
