Patent ID: 7349504

Claim:
A method for mitigating interference in a communication system comprising at least one base station and at least one terminal, a channel existing between the at least one base station and the at least one terminal, the channel comprising at least a first signal channel and a second signal channel, a first signal being communicated through the first signal channel, a second signal being communicated through the second signal channel, transmission and reception of signal in the communication system being done through the signal channels, the signal received through the channels comprising the first signal, the second signal and noise, the method comprising the steps of: a. determining channel characteristics at one receiving end, the determination of the channel characteristics being based on at least the first signal, total signal quality being based on at least the second signal, and noise characteristics, wherein the receiving end being at least one of a terminal and base station; b. computing a rate limit of the channels at the receiving end, the computation of the rate limit of the channels being based on at least the channel characteristics, the total signal quality, and the noise characteristics; c. computing a rate assignment of the channels at the base station, the computation of the rate assignment of the channels being based on control information containing at least the rate limit; and d. assigning the computed rate assignment to the channels for mitigating interference in the communication system, wherein the total signal quality is a Signal-to-all interference-plus-thermal-Noise Ratio (SINR), wherein the SINR is being computed for each of the terminals by using estimated symbols at each of the terminals, wherein symbol estimation is carried out by using one of a linear joint detection and a non-linear joint detection with group successive interference cancellation.
