Channel Aware Scheduling Algorithm for LTE Uplink and Downlink
In the past two decades, there has been a drastic increase in the mobile traffic, which is caused by the improved user experience with smart phones and its applications. In LTE system, the packet scheduler plays a vital role in the effective utilization of the resources. This field is not standardized and has immense scope of improvement, allowing vendor-specific implementation. LTE scheduling ...
متن کاملChannel Aware and Queue Aware Scheduling in LTE Uplink
Long Term Evolution (LTE) uses single carrier frequency division multiple access (SCFDMA) technique as the multiple access scheme in the uplink, due to its low peak to average power ratio (PAPR) compared to orthogonal frequency division multiple access (OFDMA). This advantage is achieved when the Resource Blocks (RBs) allocated to a user are contiguous in frequency domain. Considering this cons...

متن کاملSmart M2m Uplink Scheduling Algorithm over Lte
Currently the Long Term Evolution (LTE) System is an internationally recognized mobile communication standard for 4G. With the advent of Machine to machine (M2M) devices and network capability, a suitable uplink scheduling strategy is strongly needed for such systems. Scheduling method is one of the hot topics among current researches for M2M over LTE. It is found that there are major differenc...
متن کاملScheduling Policies for the LTE Downlink Channel: A Performance Comparison
A key feature of the packet scheduler in LTE system is that it can allocate resources both in the time and frequency domain. Furthermore, the scheduler is acquainted with channel state information periodically reported by user equipments either in an aggregate form for the whole downlink channel, or distinguished for each available subchannel. This mechanism allows for wide discretion in resour...
