Patent ID: 8121044

Claim:
A method for Code Division Multiple Access (CDMA) control segment hopping, wherein the control segment carries control information in an Orthogonal Frequency Division Multiple Access (OFDMA) packet data mobile communication system, comprising: determining a number of CDMA control segment hopping zones, each CDMA control segment hopping zone representing a frequency area for CDMA control segment hopping, according to a total number of available resources in the system and a number of resources per CDMA control segment, wherein each resource includes a predetermined number of subcarriers, or according to a total number of available subcarriers in the system and a number of subcarriers per CDMA control segment; determining start points of the CDMA control segment hopping zones using the number of the CDMA control segment hopping zones; and transmitting or receiving the control information in the CDMA control segment through CDMA control segment hopping over the CDMA control segment hopping zones using the start points.
