Comparison 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 Based allows adaptive computational complexity by introducing variable number of best branches to be stored in the search procedure.
