Key technologies of information reuse, which supports rapid collaborative design under network environment, are studied in this paper. The methods for integration modeling of information, the representation methods for information unit based on global view of the domain problem space, the model space and the active space in a design process, and the design process based on the hierarchy modeling strategy...
This paper addresses the problem cooperative downlink transmission in multicell multiantenna cellular networks. We have presented scheme for base station coordination and cooperation in MIMO with zero forcing beamformig system. Firstly, a projected channel matrices is given and it make the beams steer into the preferred user direction. Secondly, partial collaboration transmission and distributed scheduling...
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...
