A network access node selects one chunk of spectrum from a plurality of chunks of spectrum to be a primary chunk for a particular cell; transmits in the primary chunk from a broadcast channel BCH that contains information needed by a terminal to at least perform initial cell access; and uses a synchronization channel SCH to indicate which chunk of the plurality of chunks is the primary chunk. A user equipment receives a SCH in a particular chunk of spectrum; determines from it that one chunk is a primary chunk for a particular cell; tunes its receiver to a BCH in the primary chunk and uses information received on the BCH to obtain initial access to the particular cell. In various embodiments the SCH is only in the primary chunk or the SCH has some indication (e.g., cell ID or relative position of primary chunk) telling which chunk is primary.
