Title:
広帯域の通信システム内で狭帯域の信号を送信および受信するための方法および装置
Document Type and Number:
Japanese Patent JP4855385
Kind Code:
B2
Abstract:
Narrowband remote units will scan over frequencies within a wideband channel spectrum, evaluating frequency-selective channel characteristics. The best sub-channel(s) for communication will be determined and reported back to a base station via a channel-quality report message. The base station will then utilize only a narrowband portion (e.g., one sub-channel comprised of a plurality of OFDM subcarriers) of the wideband channel for transmitting data to the narrowband unit.
