Method and device for utilizing frequency bandwidth in a wireless communication system with asymmetrical traffic load

A first communication device (A/B) for wireless communication with a second communication device (C/D), which first device is provided with means for simultaneously transmitting (A) on a first frequency and receiving (B) on a second frequency, characterized in that the first device (A/B) is provided with means for, in cooperation with corresponding means in the second (C/D) device, and based on the need of each device to transmit information within a particular time interval, divide said time interval into a number of sub-intervals, the first device being provided with means for simultaneously transmitting on both the first and the second frequencies.

A system for wireless communication, comprising a first (A/B) and a second (C/D) communication device intended to transmit information to each other, where each device (A/B;

• C/D) comprises means for simultaneously transmitting on a first frequency and receiving on a second frequency, characterized in that both the first (A/B) and the second (C/D) device are provided with means for, in cooperation with each other, and based on the need of each device to transmit information during a particular time interval, divide said time interval into a number of sub-intervals, the first device comprising means (ANB) for simultaneously transmitting on both the first and the second frequencies within the said sub-intervals and the second device (C/D) comprising means for simultaneously receiving on both the first and the second frequencies within the said sub-intervals.

A method for utilizing the available bandwidth in a wireless communication system that comprises a first (A/B) and a second (C/D) communication device intended to transmit information to each other, where each device (A/B;

• C/D) can simultaneously transmit on a first frequency and receive on a second frequency, characterized in that, based on the need of the respective devices to transmit information within a particular interval of time, the said interval of time is divided up into a number of subintervals, the first device simultaneously transmitting on both the first and the second frequencies within a number of the said sub-intervals, and the second device simultaneously receiving on both the first and the second frequencies during these sub-intervals.
