The authors propose a joint bit and power loading, beamforming, Multiple Base Station set (MBS) selection and subcarrier allocation algorithm for a resource allocation problem in a uplink multicell coordinated Multi-Base-Station reception system. The objective is to minimize the total transmit power with rate constraint per Mobile Station (MS). The resources that they are considering include power, subcarrier, beamforming and the MBS set. The algorithm iteratively loads bits to the best link and subcarrier for the current rate increment and updates the Signal-to-Interference-plus-Noise Ratio (SINR) targets of all MSs on that particular subcarrier.
