  Abstract

This paper focuses on the coexistence issue between enhanced LTE (LTE-Advanced) system and current system/network. One of the main features in LTE-A is that carrier aggregation (CA) is supported by aggregating individual carriers to enhance the data rate. For LTE-A to coexist with existing LTE system or newly deployed LTE-A system, the out-of-band interfering power emitted from the aggressing LTE-A system should be limited to an acceptable level not to degrade the performance of the existing systems. In this paper, we briefly introduce the terminologies used in coexistence study and provide the deterministic analysis. And then the system simulation assumptions and results are provided for the case of aggressor 40㎒ LTE-A and victim 10㎒ LTE/40㎒ LTE-A. Based on these analysis and simulation, references of 3GPP standards in the aspect of LTE-A out-of-band TRX RF requirement are considered.
