Abstract

The coexistence performance with control channel when TD-LTE and LTE-FDD systems coexist at the adjacent frequency band within the same geographical area is investigated. A simple mathematical model mapping from control channel performance to data channel throughput is employed to estimate system performance when considering the impact of the adjacent channel interference (ACI) on the control channels. The simulation results indicate that the ACI generated by Base Station (BS) of collocated LTE system significantly degrades the performance of the uplink of the victim LTE system. The link between BSs needs an extra isolation of 83.6 dB in the typical coexistence scenarios.
