Distributed user scheduling and power allocation for collaborative multicell MIMO system

This paper addresses the problem cooperative transmission in multicell MIMO networks. Firstly, we have detailed partial collaboration downlink transmission scheme which reduce the complexity of user selection and a distributed scheduling method which prohibit complex centralized algorithm. Secondly, a distributed uplink power control method is given to coordinate user power levels to optimize overall performance. Utilizing the proposed techniques, it can reduce the inter-cell interference and improve the network performance with low complexity.
