摘要: Consider the max-min problem for an uplink SIMO heterogeneous network, where base stations (BS) are coordinated dynamically joint reception under some backhaul overhead constraints. We formulate this in perspective of power allocation, BS assignment and beamformer design, develop efficient algorithm based on alternating optimization. In particular, we transfer design subproblem into a group LASSO by applying direction method multipliers (ADMM). Consequently, is solved partially distributed manner each iteration simple closed-form solution derived. Numerical simulations demonstrate effectiveness efficiency proposed algorithm.
