Dynamic Switching of Scheduling Algorithm for Uplink LTE System

Packet Scheduling (PS) is essential in Long Term Evolution (LTE) cellular system to handle huge traffic via allocating common resources among users. The main target of PS, in LTE systems, is the Radio Resource Management (RRM) by including strategies, algorithms, and schemes to control important parameters and factors such as transmit power, data rates, modulation scheme, and error coding scheme. The paper presents a performance comparison of two scheduling schemes for LTE uplink, Best Channel Quality Indicator BCQI, and Round Robin RR schedulers. Next, a new packet scheduler for uplink LTE networks, that adapts dynamically between the two mentioned packet scheduling algorithms is proposed, evaluated and compared with the performance of the two schedulers, BCQ and RR. The results of the performance, throughput, and fairness indicate that the proposed scheme gives compromise fairness between BCQI and RR in resource distributions in the LTE and maintains the system’s capacity as high as possible. The same improvement has also been observed with delay-sensitive services traffic.
