ENERGY-AWARE RESOURCE ALLOCATION
STRATEGIES FOR LTE UPLINK WITH
SYNCHRONOUS HARQ CONSTRAINTS
ABSTRACT:
In this paper, we propose a framework for energy efficient resource allocation in multiuser
localized SC-FDMA with synchronous HARQ constraints. Resource allocation is
formulated as a two-stage problem where resources are allocated in both time and
frequency. The impact of retransmissions on the time-frequency problem segmentation is
handled through the use of a novel block scheduling interval specifically designed for
synchronous HARQ to ensure uplink users do not experience ARQ blocking.
We propose two suboptimal approaches to minimize average power allocation required for
resource allocation while attempting to reduce complexity. Results are presented for
computational complexity and average power allocation relative to system complexity and
data rate, and comparisons are made between the proposed optimal and suboptimal
approaches.
