PILOT SIGNAL TRANSMITTING METHOD, RADIO COMMUNICATION SYSTEM, AND APPARATUS AND PROGRAM USED FOR THE SAME |
摘要 |
A larger cell uses a pilot pattern with a higher pilot density in a frequency axis direction to improve a channel estimation accuracy when a frequency selective fading variation is large. Meanwhile, a smaller cell uses a pilot pattern with a lower pilot density in the frequency axis direction. A pilot pattern that each base station uses is transmitted to a mobile station in a cell as a report signal. |
