This paper investigates the performance of well known packet scheduling algorithms developed for single carrier wireless systems from a real time video streaming perspective. The performance evaluation is conducted using the downlink third generation partnership project long term evolution (3GPP LTE) system as the simulation platform. This paper contributes to the identification of a suitable packet...
Long term evolution (LTE) is the next generation wireless system that uses orthogonal frequency division multiple access (OFDMA) technology in the downlink. Packet scheduling becomes paramount as the wireless systems are moving towards all IP transmissions. Since LTE system is relatively new, very little work has been published to date that can precisely model and simulate the downlink LTE system...
This paper study the performance of an orthogonal frequency division multiple access (OFDMA) system under fractional load based in long term evolution (LTE) downlink. Fractional load is defined by a situation where only a fraction of the bandwidth is used for transmission due to lack of traffic. This type of situation should result in a global increase of signal to interference and noise ratio (SINR)...
Multimedia Broadcast/Multicast Service (MBMS) provides efficient solution for multimedia broadcasting services by distributing resources among a group of subscribers. Different from previous broadcasting services, MBMS subscribers will send feedback information which can be used to improve system performance by adapting resource allocation to channel state. In this paper in LTE frameworks we propose...
UTRAN Long Term Evolution is currently under standardization within 3GPP with the aim of providing a spectral efficiency 2 to 4 times higher than its predecessor HSUPA/HSDPA. We propose a fair channel aware search tree based packet scheduling algorithm which schedules based on the metric values designed by proportional allocation scheme. Fairness is provided by the algorithm by choosing the best metric...
This paper presents a new prioritized scheduling called prioritized fair channel-dependent scheduling (PFCDS) in enhanced universal mobile telecommunications system (EUMTS). There are some fair and efficient scheduling algorithms deriving from round-robin (RR) scheduling and C/I scheduling to achieve the trade-off between both the two extreme methods for quality-of-service (QoS). PFCDS scheduling...
