Abstract
This paper studies regional planning issues of coordinated multi-point (CoMP) transmission with perfect feedback under single-user scenario. To determine a reasonable regional planning based on semi-dynamic cooperation idea, the net ergodic capacity optimization problem is derived when given the downlink received signal expression and the definition of penalty factor. The variables that should be optimized are the number of coordinated base stations (BSs) and the dividing-area radius. In order to solve this joint optimization problem, the capacity of non-CoMP and CoMP is analyzed and simplified with knowledge of index random distribution. Again on the basis of the above simplified expression, approximate results of two plans that determine a certain relationship between the number of cooperative BSs and the cell radius are given by using the method of fixed variable and calculus formula. Simulation results show that the two approximate curves are consistent with the results obtained by Monte Carlo simulation.
