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.
