Fair QoS-Aware Scheduling in Dual-Carrier HSDPA

Abstract

With the growing need of high rate data services, 3GPP standard has investigated ways to support multimedia services with multi-carrier transmissions. Supporting high data rate guaranteeing the quality of service (QoS) and fairness of users is an important issue and should be addressed in an advanced wireless system. This paper investigates packet scheduling considering QoS of real-time traffic and fairness of non-real-time traffic through fixed delay adjustment based on multi-user PF scheduling in a dual-carrier (DC) HSDPA system. The proposed algorithm results in the QoS improvement of real-time traffic and fairness of non-real-time traffic, and the decrease of average sector throughput due to tradeoff between throughput and fairness.
