QoS Aware Logical Channel Prioritization under Burst Resource Allocation for Uplink in LTE

摘要

Long Term Evolution (LTE) is the latest 3GPP (3rd Generation Partnership Project) standard of the Mobile communication system. LTE has been proposed to achieve higher data throughput, lower latency and better quality of service (QoS). In LTE network (n/w), the resource (resource referred to frequency and time domain on the air interface) sharing is one of the major challenging issues and it is one of the key functions to achieve the desired QoS for the different configured data stream. In this context of QoS for LTE n/w, Multiplexing & Logical Channel Prioritization (LCP) is referred. In this paper, we present a brief survey on LCP techniques for the uplink (UL) direction. UL direction referred mobile to n/w communication. A strategy has been proposed for LCP to achieve QoS under burst resource allocation environment. Proposed approach considers the priority of each logical channel configured by evolved NodeB (eNB) during radio bearer (RB) setup/re-configuration.
