Leveraging Downlink for Optimal Uplink Rate Allocation: An Incentive Compatible Approach

In this paper, we consider joint uplink and downlink rate allocations over a multicast/broadcast pair in a single-cell system. We assume a network of heterogeneous users, where the uplink utility of each user is held as private information and is unknown to the base station. The challenge is to design an optimal rate allocation scheme in the presence of such incomplete information. Here, we provide an incentive-compatible mechanism that leverages downlink demand to ensure that users truthfully reveal their uplink utilities, resulting in a socially optimal uplink rate allocation.
