PFGBR Scheduling for Streaming Services over Wideband Cellular Network

This paper considers the multi-user scheduling for streaming services over wideband frequency-selective and time varying channel in cellular network such as E-UTRAN. First, the frequency-selective proportional fair (PF) scheduling is proposed for multi-carrier system under user´s maximum transmission power capability and continuous resource constraints, which is used to reduce the peak to average power ratio (PAPR) for uplink. In addition, the proportional fair with guaranteed bit rate (PFGBR) is proposed to enhance the quality of service (QoS) of streaming service and improve the user experiences in terms of data rate and delay. The PFGBR is to optimize the concave utility function of Sigma_i log R_t while provides guaranteed bit rate (GBR) specifically for streaming applications. The system simulation results for both frequency-selective PF and PFGBR are presented and it shows that the PFGBR can achieve better dynamics of rate and delay than PF algorithm.
