Abstract
A method and system for assigning unique words in an SDMA (spatial division multiple access) 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 set of unique words by determining which unique words are likely to interfere with adjacent base stations, and setting those words to a low priority. In this way, over time, the base station assigns unique words that have a lower level of correlation to allow for better signal differentiation and improved communication sensitivity. When a mobile device enters a base station's geographic area, it generates an establish request message that indicates what unique word it is using in the adjacent cell. The base station extracts this unique word, and sets it to a low priority in its set of unique words. The base station is therefore able to assign unique words that facilitate improved communications.
