60 GHz Frequency Sharing Study between Fixed Service Systems and Small-Cell Systems with Modular Antenna Arrays

This paper presents numerical simulation results in order to identify how much interference can be generated to a fixed service (FS) receiver from nearby small cell networks when the FS systems and small-cell systems are sharing a 60 GHz mmWave frequency band. For this 60 GHz frequency sharing study, two different scenarios are considered, i.e., the aggregation of interference into an FS receiver occurred by every transmission (i) from base stations (BSs) to their associated user elements (UEs); (ii) from UEs and their associated BSs. Moreover, 60 GHz mmWave specific propagation characteristics and attenuation factors are considered for more precise simulation study. The simulation results determine how much interference rejection is required to protect the operation of FS.
