Downlink mixed-traffic scheduling with packet division multiplexing

With the tremendous growth in the wireless communications industry, wireless networks are envisioned to provide always-on, seamless and ubiquitous wireless data services with different Quality of Service (QoS) requirements to a large number of users using a mix of real-time and non-real-time multimedia traffic. In this paper, we propose an Adaptive Cross Layer (physical, MAC and application) Scheduling with Flow and User Multiplexing (ACLS-FUM) scheduling policy and quantify the considerable QoS performance gains in terms of user throughput, user latency, user packet drop probability and user jitter in a mixed traffic environment. Improvements from increased packing efficiency and time slot availability achieved with packet division multiplexing (PDM) (which permits the base station (BS) to service multiple users in the same physical encoder packet in a single time slot) are presented.
