Abstract

The power efficient mechanism for MTC (Machine type communication) UEs in LTE-A networks is investigated in this paper. Extending paging cycle has been verified as one efficient method to reduce the power consumption for MTC UE. However, unnecessary SI( System Information) acquisition will be introduced if the extended paging cycle is larger than MP (Modification Period). Therefore, a two-MP based SI acquisition mechanism is proposed in this paper to fully eliminate the unnecessary SI acquisition. According to simulation results, the power consumption will be reduced greatly with the proposed mechanism.
