Abstract

We consider the problem of long-term transmit point (TP) association in a heterogeneous network where CoMP (Coordinated Multiple Point) transmission scheme is supported. More specifically, the TP association is designed for a relatively long time period where only channel statistics is available, and each user equipment(UE) could be associated with a number of TPs. We formulate the problem as a two-stage stochastic optimization problem with ℓ1- norm regularization, and propose a stochastic sparse WMMSE (SS-WMMSE) algorithm to solve it. The simulation results show that the proposed algorithm significantly outperforms the traditional deterministic approach.
