摘要： Disclosed are a base station, a relay station, and a terminal according to a method for designing a cellular system for improving resource usage efficiency by reducing interference between relay stations and interference between the base station and the relay station. The relay station gets control signals that terminals served by the base station transmit, and registers terminals, levels of the control signals of which are bigger than a predetermined value, to a list of the interference terminals. The relay station checks an interference resource through resource allocation information of the base station, checks an available resource corresponding to a resource except the interference resource among a resource allocated by the base station, and allocates some of the available resource to the terminal.

摘要： A communication resource allocation method for solving resource request imbalance content in a cell is provided. Considering a propagation environment, the base station allocates a whispering resource to a whispering area, the whispering resource being one part of the communication resource and the whispering area being a peripheral area of the first base station, and allocates a speaking resource to a speaking area, the speaking resource being other parts of the communication resource and the speaking area being a border area of a cell. When the resource request of the whispering area is increased, the base station further allocates a part of the speaking resource to the whispering area or increases a ratio of the whispering resource. When the resource request of the speaking area is increased, the base station controls a threshold value for identifying the whispering and speaking areas or increases a ratio of the speaking resource.

摘要： A transmission control method and apparatus in a collision interval during a collision of multidimensional hopping patterns. The present invention hopping-selects an orthogonal wireless resource in the area of the multidimensional orthogonal resource according to communication standards negotiated between a transmitter and a receiver, a corresponding channel being distinguished by the hopping pattern. The present invention allocates a specific multidimensional hopping pattern by the second stations. The hopping pattern is permanently allocated to the second stations or from the first station during a call set up. The permanent allocation of the hopping pattern to the second stations is achieved when the hopping pattern is identified based on a unique identifier. Such as ESN of the second station. The hopping patterns of the second stations are mutually independent so that the coordinates of the same orthogonal resource is allocated to different second stations in a simultaneous manner in a predefined moment.
