Abstract

Carrier Aggregation (CA) has been regarded as an important technology for Long Term Evolution-Advanced (LTE-A) which is currently standardized in the Third Generation Partnership Project (3GPP). CA is introduced to meet the requirement of very-high-rate-data transmission over wide bandwidths e.g. up to 100MHz. In this paper, the problem of power allocation restriction in the LTE-A system with CA has been discussed. Furthermore, a possible solution to set the Relative Narrowband Transmit Power (RNTP) threshold which is used to restrict the eNodeB transmit power of each carrier is proposed and the performance is evaluated. The results of proposed method in terms of first transmit success ratio, average and outage cell throughput are provided through system simulation.
