Embodiment 1
[0098] In this embodiment, a wireless channel environment conforming to Rayleigh fading is established and a base station and user topology are established, which includes a single macro base station located in the center of the topology, multiple small cells and users randomly distributed in positions. In the user access phase, the user feeds back the link status indication and channel gain information to the macro base station based on the link channel conditions, and the macro base station maximizes the product of the number of service base stations for each user based on the received information, and the optimal solution of the problem can be obtained through integer programming The optimal solution is the optimal user access instruction, and the user access instruction is sent to the user and the small cell, and the user and the small cell establish a link according to the access instruction. In the power allocation stage, each small cell sends a signal to the user accessi...
