The invention discloses a method for achieving collaborative multipoint transmission dispatch and power distribution. Aiming at each PRB, the method adopts the
algorithm of transmission dispatch for determining a user of a collaborative cluster and dispatch, namely, RSRP values are counted, SINR is calculated according to the RSRP values and a current condition, edge users which are served in each
cell of each
base station are found out, the collaborative cluster and the edge users which are served by the collaborative cluster are determined in an iterating mode, and an idle
base station selects central users of the
cell to conduct serving; power pre-distribution is conducted through a water-filling
algorithm on each
base station; a non-cooperative game is adopted in each PRB to conduct interference coordination and optimum allocation of power is achieved. The method has the advantages that a
collaboration method is adjusted according to real-time dynamic conditions of the
system parameters of each PRB, dispatch is flexible and adaptability is strong; by the adoption of the centralized transmission dispatch scheme, expenditure of
algorithm time
delay is low and real time performance is strong; due to the fact that the non-cooperative game is adopted to achieve interference coordination in CoMP, power distribution is reasonable and handling capacity of the edge users is improved.
