The transmitter optimization, to maximize the downlink sum rate of a multiple antenna cellular system with perfect data cooperation between the base stations and a separate power constraint per base station, was discussed. The incremental power allocation strategies combined with BC-MAC duality results were analyzed to perform the non-convex downlink transmitter optimization. The analysis showed that with optimal power allocation, the transmit power of a user was decreased as the overall transmit power increased.
