ABSTRACT:
A terminal211measures pilot signals transmitted in directional (beam) patterns from an adjacent cell and an own cell, and estimates reception qualities with the presence (high)/absence (low) of the interference from the adjacent cell. The terminal211requests data rate request values (DRC1, DRC2) corresponding to the reception qualities with the presence/absence of the interference to the base station201. The base station201shares beam direction schedule with an adjacent cell base station, and confirms the presence/absence of interference to the terminal211for each slot. In accordance with the presence/absence of the interference, the base station201selects a suitable one of the two values of the data rates requested from the terminal211, and modulates the data and transmits it.
