Abstract  Abstract

Narrowband remote units 101-103 scan the frequencies within the wideband channel spectrum to evaluate frequency-selective channel characteristics. The best sub-channel (s) for communication are determined and reported back to base station 104 via a channel-quality report message. The base station then uses only the narrowband portion, e.g., only the narrowband portion of the wideband channel that transmits data to the narrowband unit, where one sub-channel consists of multiple OFDM sub-carriers.
