Allocation Algorithms (RAAs) are an area of work where
researchers are seeking to optimize the efficient use of scarce
radio resources. The selection of an optimal Modulation and
Coding Scheme (MCS) that allows LTE to adapt to channel
conditions is a second area of ongoing work. In the wireless
part of LTE, these two factors, RAA and MCS selection are the
most critical in optimization. In this paper, the performance of
three resource allocation schemes is compared, and a new
allocation scheme, Average MCS (AMCS) allocation, is
proposed. AMCS is seen to outperform both “Minimum MCS
(MMCS)” and “Average Signal to Interference and Noise Ratio
MCS (SINR AMCS)” in terms of improvements to LTE UL
performance. The three algorithms were implemented in the
Vienna LTE-A Uplink Simulator v1.5.
