BASE-STATION DEVICE AND COMMUNICATION METHOD

摘要

By a base station that is not limited to a cell concept, the system control cost is controlled and an area of high-communication-speed/high-communication-quality is expanded. There are provided fixed-cell support base-station devices 420 and 421 having functions of physical layer processing and higher layer processing according to the cell concept in the related art and an unfixed-area support base-station device 430 having a physical layer processing function that is not limited to the cell concept. The unfixed-cell support base-station device 430 performs physical layer signal processing for a terminal in a low throughput area and selects an arbitrary antenna group from antennas or antenna group linked to the fixed-cell support base stations 420 and 421, and the fixed-cell support base stations 420 and 421 transmit their own transmission signals and transmission signals directed to the terminal together.

主权项

1. A base-station device comprising:
a first base station unit which is connected with a first antenna and supports a first fixed cell; a second base station unit which is connected with a second antenna and supports a second fixed cell; and a communication unit which performs communication with the first base station unit and the second base station unit and supports an unfixed area, wherein the first base station unit transmits a first reference signal to a terminal and receives quality information calculated by the terminal using the first reference signal, the communication unit selects a specific antenna from the first antenna and the second antenna in a case where the quality information satisfies a predetermined condition, and generates a transmission signal to the terminal by performing baseband processing, and the generated transmission signal to the terminal is transmitted from the selected specific antenna to the terminal.
