Abstract:
1. A method of processing signals in a communication system, comprising: receiving a downlink subframe comprising a preamble, first and second sets of downlink subframe parameters, and a plurality of data within a predetermined frequency band, wherein said first set of downlink subframe parameters comprises channel parameters and said second set of downlink subframe parameters comprises adaptive antenna system (AAS) parameters; processing data in said preamble to obtain channel quality indicator (CQI) information; and using said CQI information to select either said first set or second set of downlink subframe parameters to process said data in said downlink subframe; initially searching all scannable frequencies within said frequency band for said channel parameters if said CQI information is below a predetermined level; and subsequently searching all scannable frequencies in said frequency band for said AAS parameters if no channel parameters are detected in the initial search.
