We present a method to reduce the device battery consumption to efficiently support battery-operated machine-to-machine (M2M) communication in 3GPP long-term evolution. The long-term evolution discontinuous reception (DRX) is a key mechanism in reduc

This paper discusses the requirements on future radio access and, based on the requirements, proposes a framework for such a system. The proposed system based on orthogonal frequency-division multiplexing supports very low latencies and data rates up

We present a method to reduce the device battery consumption to efficiently support machine-to-machine (M2M) communication in LTE. We first introduce a model for calculating energy consumption of a LTE device. We assume that the M2M device transmits

This paper considers transmission of scheduling information in OFDMA-based cellular communication systems such as 3GPP long-term evolution (LTE). These systems provide efficient usage of radio resources by allowing users to be scheduled dynamically i

We study the uplink control signaling in 3GPP-Long Term Evolution (LTE) systems. Specifically, we propose a precoding method that uses complex-field coding (CFC) to improve the performance of the PUCCH format 2 control signaling. In the case of perfe

Control signaling strategies for scheduling information in cellular OFDM systems are studied. A single-cell multiuser system model is formulated that provides system capacity estimates accounting for the signaling overhead. Different scheduling granu

A framework for future radio-access systems, enabling user data rates up to 100 Mbps with wide-area coverage and up to 1 Gbps for local-area coverage, is presented. The proposed framework supports flexibility in system bandwidth and duplex arrangemen

High-speed downlink packet access (HSDPA) is included in release 5 of the WCDMA specifications to increase downlink capacity and bitrates. This paper considers performance aspects of streaming applications over HSDPA in a mixed streaming and best-eff

This paper discusses the TPC detection performance in soft handover in WCDMA. A simple TPC commands combining method is evaluated and an improved TPC combining method is proposed. Results show that although the simple combining method fulfills the 3G

Several scheduling algorithms are evaluated for the HS-DSCH channel in a WCDMA mixed traffic scenario. The traffic consists of FTP and Web surfing users. The maximum channel quality indicator (CQI) scheme serves users with the highest channel quality
