CONFIGURATION OF OVERHEAD CHANNELS IN A MIXED BANDWIDTH SYSTEM
First Claim
1. A mobile station adapted to acquire a sync channel message using a wireless device operable in at least one of a single carrier mode in a single carrier system and a multi-carrier mode in a multi-carrier system, comprising:
- a first receive subsystem for receiving some data components of forward link data comprising a sync channel message on at least one of a set of preferred frequency channels included within a predetermined set of frequencies in a personal communications system (PCS) block of frequencies; and
at least one additional receive subsystem comprising multiple bands of adjacent of said frequency channels each said band including said one of a set of preferred frequency channels for simultaneously receiving remaining components of said forward link data.

Abstract
A method and apparatus for transmitting broadcast information in a multi-carrier communication system. The Sync Channel of the multi-carrier system is transmitted a 1.25 MHz channel bandwidth (i.e., over a single carrier), and to specify the preferred channels for the Sync Channel transmission instead of the preferred channels for the entire multi-carrier system. The Sync Channel Message will carry additional information indicating the center frequency of a multi-carrier system within a reserved set of frequency bands and indicating the frequency of a single carrier system in the reserved set of frequency bands. Considering the A block of the PCS band again, the preferred channels for Sync Channel transmission can be selected as channels 75, 150 and 225. This selection ensures that one of the preferred channels will always be used by any multi-carrier system regardless of the location of its center channel.
