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 کاملLTE Uplink Scheduling - Flow Level Analysis
Long Term Evolution (LTE) is a cellular technology developed to support data traffic at potentially high rates. It is foreseen to extend the capacity and improve the performance of current 3G cellular networks. A key mechanism in the LTE traffic handling is the packet scheduler, which is in charge of allocating resources to active flows in both the frequency and time dimension. In this paper we...
متن کاملComparison of Channel Dependent Scheduling Policies in LTE Uplink
In this paper, three scheduling schemes are evaluated in different scenarios for SC-FDMA used in LTE uplink, First maximum expansion and recursive maximum expansion are powerful in terms of gain over round robin but suffers from poor fairness results, Search-Tree Based Algorithm guarantees same amount of bandwidth for each user and yet improve the performance by factor 0.5 up to 1.2. SearchTree...
