Joint Resource Allocation for Uplink and Downlink in Wireless Networks: A Case Study With User-Level Utility Functions

Free registration required

Executive Summary

In most of researches in resource allocation for wireless networks, uplink and downlink problems are considered separately, especially when resources for uplink and downlink are statically partitioned, as in FDD and static TDD systems. However, even in those systems, joint resource allocation for uplink and downlink can improve system efficiency and the authors study this issue in this paper with the concept of the user-level utility function. In most cases, a user has a two-way communication that consists of two sessions: uplink and downlink sessions and its overall satisfaction to its communication depend on its satisfaction to each of its sessions.
