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.
