—Femtocells are low-cost, miniature base-stations intended to improve indoor coverage in 3G networks and beyond. One of the main issues in adopting femtocells en masse is the surge in interference to the mobile users served by the macrocell arising from unplanned networks and private access. Therefore, distributed power control mechanisms for femtocells are(More)
— The need for Inter-cell Interference Coordination (ICIC) schemes in LTE heterogeneous networks, is well elucidated in literature [1]. We consider distributed scheduling mechanisms so that multiple base-station vendors can co-exist. Moreover, in legacy LTE networks, fast timescale coordination across base-stations may not be possible due to the inherent(More)
We consider energy-efficient resource allocation for wireless fading channels. We study the case where a sliding window ARQ protocol such as Go-Back-N is used to provide reliable communication. In particular, we consider power allocation policies that take into account the underlying window dynamics. An optimal dynamic programming approach and a sub-optimal(More)
We consider scheduling problems for downlink data transmission in wireless networks. There are multiple users in the system and each user is assigned a utility function that depends on queue length at the base station. Due to the burst error nature of the wireless channel, re-transmissions sometimes are necessary for providing reliable communications. Here(More)
