Abstract

The Long Term Evolution (LTE) technology is ubiquitously implemented today and it achieves noticeable success in fulfilling the data transmission demand instigated by the unprecedented growth of mobile services. However, the LTE might fail to provide qualified services for Machine Type Communications (MTC) and the emerging Tactile Internet, as both require data being transmitted with extremely low latencies (0.5-5 ms). In this paper, we propose a novel predictive Semi-Persistent Scheduling (SPS) scheme with the corresponding SPS scheduler that takes advantage of transmission history, to effectively reduce the uplink latency of LTE systems. Moreover, the proposed SPS design is compatible with..
