Abstract  Abstract

Narrowband remote units (101-103) scan over frequencies within a wideband channel spectrum evaluating frequency-selective channel characteristics. The best sub-channel(s) for communication is determined and reported back to a base station (104) via a channel-quality report message. The base station then utilizes only a narrowband portion for example one sub-channel comprised of a plurality of OFDM subcarriers of the wideband channel for transmitting data to the narrowband unit.
