QPPS : Qos Provision Packet Scheduling Algorithm in High Speed Downlink Packet Access
-The 3 Generation WCDMA standard has been enhanced to offer significantly increased performance for packet data. But coming application such as multimedia on desiring data rates will urge the UMTS support. To support such high data rates, High Speed Downlink Packet Access (HSDPA) labeled as 3.5G wireless system, has been published in UMTS Release 5. Under the HSDPA system, it will have to suppo...
متن کاملIssues in Scheduling Multimedia Traffic over the High Speed Downlink Packet Access (HSDPA) link of UMTS
In this paper, some issues in scheduling multimedia traffic over the HSDPA link of UMTS are addressed. Unlike previous contributions, the focus is on the case where packets having different QoS attributes need to be delivered to a specific user as part of a multimedia application packet delivery process. The following packet scheduling algorithms were considered: Max C/I, Proportional Fair (PF)...
متن کاملHigh-speed Downlink Packet Access
This chapter presents High-speed Downlink Packet Access (HSDPA) for WCDMA—the key new feature included in Release 5 specifications. The HSDPA concept has been designed to increase packet data throughput by means of fast physical layer (L1) retransmission and transmission combining as well as fast link adaptation controlled by the Node B (Base Transceiver Station (BTS)). This chapter is organise...
متن کاملCombined beamforming and scheduling for high speed downlink packet access
Joint operation of High Speed Downlink Packet Access (HSDPA) and adaptive antennas in a WCDMA cellular network is considered. The total throughput per cell of HSDPA depends heavily on the strategy employed by the scheduler. It is argued that the maximum SIR scheduler, which maximizes throughput in the single antenna system by serving only the user with best momentary channel quality, will not s...
متن کاملHigh Speed Downlink Packet Access: WCDMA Evolution
This article gives an overview of the high speed downlink packet access (HSDPA) concept; a new feature which is coming to the Release 5 specifications of the 3GPP WCDMA/UTRA-FDD standard. To support an evolution towards more sophisticated network and multimedia services, the main target of HSDPA is to increase user peak data rates, quality of service, and to generally improve spectral efficienc...
