Mobility Performance Analysis under Different SCell Measurement Periods in the LTE-A System with Carrier Aggregation
In order to achieve up to 1 Gb/s peak data rate in future International Telecommunications Advanced mobile systems, carrier aggregation technology is introduced by the 3GPP to support very-high-data-rate transmissions over wide frequency bandwidths (e.g., up to 100 MHz) in its new LTEAdvanced standards. In this paper, two carriers are considered, namely primary component carrier (PCell) and secondary component carrier (SCell). Appropriately loosening SCell measurement period is able to save UE power consumption without apparent effect on the system performance. This paper analyzes system mobility performances under various SCell measurement periods. Furthermore, it gives the least length a SCell measurement period could be relaxed to while still retaining the system performance in scenario 2.
