Abstract

Techniques are provided to assign radio resources with one of two or more types of assignments on a frame-by-frame basis. The first type of assignment uses subcarriers that are contiguous in both time and frequency, and the second type of assignment uses subcarriers that are disjoint and equally-spaced in frequency. The types of resource assignments can be multiplexed in a frame by dividing the frame into two zones, each zone of a different type. The demarcation between the first and second zones is implicitly indicated by the assignment messages for the mobile stations. Based on the loading conditions, the base station selects one of two demarcation strategies to use and communicates the selection implicitly by using one assignment message for a mobile station.
