A cross-layered time-frequency scheduling and resource allocation algorithm
CLSA
is proposed for downlink in OFDMA systems.The CLSA aims at improving system throughput and outage.Besides
some other QoS metrics were considered too
such as physical channel state information as well as users’requirements on throughput
delay and packet error rate (PER).The performance of CLSA and related analysis were evaluated by amounts of simulations.Compared with the classic algorithms
the Modified Proportional Fair (MPF) algorithm and the Modified Largest Weighted Delay First (M-LWDF) algorithm
CLSA shows excellent performance in system effective throughput and outage of OFDMA system in simulations.
