摘要

我们考虑在混合LTE和802.11无线接入技术(rat)的异构网络中按比例公平分配速率，该网络支持多路径和多归属操作(同时连接用户设备到多个LTE BSs和一个802.11 AP)。我们表明，效用公平优化问题是非凸的，但可以通过以分布式方式解决一系列凸优化来找到全局最优。其结果是一种原则性的方法，可以从LTE卸载到802.11，并利用LTE/802.11路径多样性来满足用户流量需求。

Utility fair RAT selection in multi-homed LTE/802.11 networks

We consider proportional fair rate allocation in a heterogeneous network with a mix of LTE and 802.11 Radio Access Technologies (RATs) which supports multipath and multi-homed operation (simultaneous connection of a user device to multiple LTE BSs and one 802.11 AP). We show that the utility fair optimisation problem is non-convex but that a global optimum can be found by solving a sequence of convex optimisations in a distributed fashion. The result is a principled approach to offload from LTE to 802.11 and for exploiting LTE/802.11 path diversity to meet user traffic demands.
