Hybrid scheduling scheme for a cooperative relay system in heterogeneous traffic environments

Abstract

We propose a hybrid scheduling scheme which can efficiently support various types of traffic in a cooperative relay system of downlink cellular networks. The hybrid scheduling scheme harmonizes the shared-channel resource allocation scheme and dedicated-channel resource allocation scheme to accommodate various traffic in heterogeneous traffic environments. We show that the proposed scheme significantly improves the system performance in terms of system throughput in heterogeneous traffic environments through the analysis of the system capacity and throughput.

Multi-Flow Scheduling for Coordinated Direct and Relayed Users in Cellular Systems

“…Each of the complex channels h ij , i, j ∈ {B, L, R, D}, is reciprocal, known at the receiver. We assume all the channels are known at the BS as in [14], [15]. Each user requests an uplink and a downlink transmissions to the BS.…”
