摘要： Systems and methods allow cell acquisition in a wireless communication system in frequency division multiple access mode of operation. Code sequences transmitted over primary synchronization channel (P-SCH) enable detection of symbol boundary, cyclic prefix duration, and indication of broadcast channel bandwidth. Sequences transmitted over secondary synchronization channel (S-SCH) afford radio frame boundary detection, cell identification, and broadcast channel bandwidth indication. Cell identification can be conveyed jointly between P-SCH and S-SCH codes. Broadcast channel sequences convey cyclic prefix timing, system bandwidth, and other system information. Relay of cell acquisition information, as well as multiple-cell acquisition when wireless system operates with frequency reuse are described.
