Embodiment Construction
[0035] The present invention will be further described below in combination with specific embodiments.
[0036] Assuming that a downlink environment of a heterogeneous cellular network is considered, the environment includes a macro base station and multiple small base stations, and multiple users are randomly distributed within the coverage of the cell, where the number of users is represented by N, and its set is: U={1, 2,...N}, the number of base stations is M, and its set: B={1, 2,...M}, when B=1, it is expressed as the index of the macro base station, and the base station j∈B The transmission power is p j , all base stations work in the same frequency band and the frequency reuse coefficient is 1, the system bandwidth is W, and the channel model is a Rayleigh fading channel with an average value of 1. The channel gain between base station j and user i is h ij , then if user i is associated with base station j, the downlink signal-to-interference-noise ratio from base st...
