Abstract

This invention is concerned with a transmission control method and apparatus in a collision interval for a collision of multidimensional hopping patterns. In the present invention, each orthogonal wireless resource in the coordinate of the multidimensional orthogonal resource can hop according to the hopping pattern negotiated between a transmitter and a receiver, and each corresponding channel is distinguished by the hopping pattern. A specific multidimensional hopping pattern is allocated to each secondary station. The hopping pattern is either permanently allocated to the secondary stations or temporarily allocated from the primary station during a call set-up. The permanent allocation of the hopping pattern to the secondary stations is achieved when the hopping pattern is identified based on a unique identifier, such as ESN of the secondary station. The hopping patterns of the secondary stations are mutually independent so that the coordinates of the same orthogonal resource is allocated to different secondary stations in a simultaneous manner in a specific moment. Through this invention, in order to improve the performance of the multidimensional resource hopping multiplexing system, refining transmission and perforation mechanisms for the collisions of multidimensional resource hopping patterns can reduce the overall perforation probability.
