Interference Situation Adaptation Scheme for Organized Beam-hopping Based Systems

In organized beam-hopping (OBH) based systems, the organized hopping pattern is changeable according to the distribution of the mobile stations (MS) in the cell. However, the changed beam-hopping patterns may cause severe co-channel interference for the users which are hit by more than one beam. In this paper, we develop an interference situation adaptation scheme for OBH-based systems. The interference situation adaptation scheme is based on the required quality-of-service (QoS) of the user, and helps the users to avoid severe co-channel interference. Specifically, the data transmission will adaptively select a separately serving mode, a diversity mode, or even a data splitting mode. Key-Words: Organized beam-hopping, interference, adaptation, beamforming.
