Abstract
A method and system for assigning unique words in an SDMA communication system is disclosed. A base station has a set of available unique words from which to select and assign unique words. The base station prioritizes the unique words by determining which unique words are likely to interfere with adjacent base stations, and setting those words to a low priority. Thus, over time, the base station assigns unique words that have better cross correlation characteristics and improved communication sensitivity. The base station discovers the unique words likely to be used in adjacent base stations by direct communication with adjacent base stations, or by communicating with a central office facility. Alternatively, the base station may be made aware of the unique IDs for adjacent base stations, and use these IDs to determine a set of unique words likely to be used by these adjacent base stations.
