Abstract
This paper investigates an adaptive interference mitigation (AIM) technique at International Mobile Telecommunications for 2020 (IMT-2020) base station (BS) transmitters to improve the frequency sharing of terrestrial and satellite systems. In contrast to the conventional schemes, we take into account the mobile earth station (MES) and planar array antenna (PAA) rather than the fixed earth station (FES) nor linear array antenna (LAA), respectively. MES motion has an effect on the interference mitigation (IM) performance mainly due to the uncertain MES location resulting in exceeded interference. This paper firstly modeled the MES mobility and then derived the relation between MES velocity and MES location updating period. An adaptive interference mitigation (AIM) scheme is proposed next. Furthermore, simulation results are presented to illustrate the performance of the proposed scheme.

Notes
- 1.
In case the database does not exist or unavailable, other techniques such as spatial spectrum estimation should be adopted to acquire the MES direction.
- 2.
This IM algorithm would require the use of other frequencies to cover the area where the BS transmit antenna gain is reduced, here specified as \( \theta_{NS} \).
