Patent ID: 8396141

Claim:
An apparatus in a communication system that includes a plurality of cells, wherein the cells transmit respective signals that include respective pilots through respective channels to a terminal, the apparatus comprising: a signal strength estimator configured to generate first estimates of at least one of signal strengths and signal-to-interference ratios of signals received from respective cells; an estimator configured to generate second estimates of at least one of a frequency selectivity, a time selectivity, and an antenna selectivity of respective channels between the terminal and respective cells; and a cell selector configured to generate a cell selection based on the first estimates and the second estimates; wherein the signals are orthogonal frequency division multiplex signals, the second estimates of the frequency selectivity of the channel include estimates of at least one of a coherence bandwidth and a delay spread of the channel, and the estimator is configured to generate the second estimates of the frequency selectivity by calculating a correlation in signal strength between pilots at different frequencies and at a same time instant.
