Throughput-aware resource allocation for QoS classes in LTE networks
In LTE systems, multicast services must be delivered efficiently in response to the need for strong QoS support. However, each class of quality services has its own requirements to be satisfied.

| description | In LTE systems, multicast services must be delivered efficiently in response to the need for strong QoS support.
However, each class of quality services has its own requirements to be satisfied. These quality constraints limit the scheduling flexibility, and the LTE downlink resource allocating algorithms need to assimilate these constraints while trying to maximize system performance in terms of fairness and throughput. This paper addresses
this fundamental problem of LTE downlink scheduling by adopting the time-domain Knapsack algorithm over the
traffic overload patterns. We fine tune the Knapsack algorithm, to overcome this problem and improve system
performance objectives. We demonstrate that more efficient performance can be achieved in terms of fairness index and system throughput, which is evaluated using simulation results.
