Title:
周波数再利用方式を実施するための無線通信システムにおける方法および装置
Document Type and Number:
Japanese Patent JP3621113
Kind Code:
B2
Abstract:
A radio communication system (100) implements a frequency reuse plan by sending a message (308) simultaneously with other messages in a plurality of cell clusters (202-208) utilizing the frequency reuse plan, which provides a message carrier-to-interference ratio (C/I) sufficient for reception of the message when a receiver (104) is adjusted in accordance with a periodically transmitted pilot symbol (402-408). The C/I is smaller than preferred for reception of the pilot symbol. The pilot symbol is periodically transmitting simultaneously with other pilot symbols in a time diverse manner such that pilot symbol transmissions for adjacent ones of the plurality of cell clusters occur in non-overlapping time slots, thereby generating the larger C/I preferred for reception of the pilot symbol. The pilot symbol and the message are received by the receiver, and the receiver is adjusted in accordance with the pilot symbol to demodulate the message.
