Discontinuous Reception (DRX) is one of the mechanisms to reduce User Equipment (UE) power consumption in Long Term Evolution (LTE) systems. In this work, a DRX-aware power and delay optimized scheduling scheme is proposed for downlink transmission of bursty packet data traffic. The UE power consumption is minimized by reducing the time that a UE spends receiving data. This is achieved by predominantly...
In this paper mobility performance is studied in heterogeneous networks with both macro and indoor base stations. Due to abrupt changes in received signal and interference level as User Equipment (UE) enters and leaves a building with indoor Home eNodeB (HeNB) there may be additional challenges for handover compared to more homogeneous network layout. The purpose of this paper is, with dynamic system...
In this paper we study the performance of idle mode mobility state detection schemes targeted for 3rd Generation Partnership Project (3GPP) Evolved UTRAN. The purpose is to compare the mobility state detection scheme specified in 3GPP Release 8 and a dual trigger scheme for 3GPP Release 9 using different User Equipment (UE) velocity conditions and cell reselection triggering sensitivity levels. A...
