Radio resource management in HSDPA and HSUPA

Bell Labs Technical Journal (2007)

Stefan Brueck E. Jugl Hans-Juergen Kettschau Michael Link Jens Mueckenheim

This paper discusses the interaction between high speed downlink packet access (HSDPA) and high speed uplink packet access (HSUPA) scheduling algorithms running in the Node B and other resource management algorithms in the radio network controller (RNC), which are still required to satisfy user-perceived quality. We investigate the effect of load sharing with legacy dedicated channel transmission, and discuss load control algorithms suitable for HSDPA and HSUPA packet transmission. The main concepts of resource allocation are discussed together with results obtained from a dynamic system simulator developed by Alcatel-Lucent. © 2007 Alcatel-Lucent.

Limits of sectorisation gain caused by mobility and soft handoff

Electronics Letters (1999)

E. Jugl Holger Boche

The improvement of the capacity of mobile communication systems by sectorisation of radio cells is assessed to be too optimistic at present. The authors point out the limits of the sectorisation gain caused by the mobility behaviour of the subscribers and soft handoff. In environments with few subscribers a substantial loss of this gain occurs.

Algorithm for construction of (0,1)-matrix codes

Electronics Letters (1997)

E. Jugl Thomas Kuhwald K. Iversen

A new algorithm for the construction of (0, 1)-code matrices based on the Greedy algorithm is proposed which allows the generation of code matrices with any desired matrix dimension and weight. Such codes are very useful in incoherent optical code-division multiple-access (CDMA) systems combining wavelength hopping and time spreading. So it is possible to achieve an auto-correlation function with zero sidelobes and an aperiodic cross-correlation function with a maximum value of one.

DEFINITION OF SUITABLE SIMULATION SCENARIOS FOR DYNAMIC INVESTIGATIONS IN CELLULAR NETWORKS WITH “STEAM”

Holger Pampel E. Jugl

This paper gives an overview on the definition of simulation scenarios for the dynamic system level cellular simulation tool STEAM used within Lucent Technologies for the investigation of radio resource management algorithms in GSM and UMTS networks. It discusses the creation of so-called “wrap-around” scenarios and equal cell loading. Afterwards the influence of dynamic effects like mobility, queuing of incoming calls and filtering of measurements on the simulation results is discussed briefly.

D/sup 2/-ary signaling for incoherent all-optical CDMA systems

K. Iversen Thomas Kuhwald E. Jugl

A new method for two-dimensional multi-ary signaling in optical networks is presented, which combines two signaling schemes, D-ary PPM and D-ary FSK. Jointly with code-division multiple-access (CDMA), higher data rates than in conventional CDMA systems and larger network sizes can be achieved. Also fewer frequencies than in wavelength division multiplexing (WDM) are required.

Downlink beamforming and data rate adaptation applied for packet data transmission over the UMTS dedicated channel

E. Jugl M. Schact Armin Dekorsy J. Muckenheim

In this paper system level simulation results from the performance evaluation of applicable downlink beamforming concepts for UMTS are presented. For the first time the combination of beamforming and packet data services over UMTS dedicated channels in conjunction with data rate adaptation is investigated. The main focus of this paper is to assess realistic system capacity gains of the different beamforming concepts regarding UMTS specific conditions. Special focus is paid on the comparison of 3/6 sector scenarios with fixed beam switching (FBS) and beam pointing (BP). When applying FBS and BP with 4 antenna elements (4 beams for FBS) a cell throughput gain of about 180...190 % is reached compared to 3 sectors scenario. This gain is coming along with a reduction of the required downlink transmit power dedicated to a specific user. Moreover, due to the lower complexity of the FBS concept and the comparable capacity gain, FBS is preferred to BP

Dynamic pilot power allocation in CDMA systems

Fifth IEE International Conference on 3G Mobile Communication Technologies (3G 2004) The Premier Technical Conference for 3G and Beyond (2004)

E. Jugl

In this paper a new concept for the pilot power allocation in code division multiple access (CDMA) mobile communication systems is introduced. The drawback of current constant pilot power allocation is the so-called cell breathing effect. The introduced concept of a dynamic pilot power allocation scheme tries to adapt the actual pilot power according to the current load situation in the cell. Thus, on the one hand the radio emission can be reduced when the cell is in low loaded condition, and on the other hand more subscribers can be served in highly loaded cells. This results in an increased overall capacity of the CDMA system.

Influence of biased sampling on mobile communication systems

E. Jugl Holger Boche

The phenomenon that the probability density function (PDF) of the velocity of the boundary-crossing subscribers is different from that of all other subscribers has already been known for a long time (called biased sampling). This paper investigates the implication of this phenomenon with regard to the channel holding time and thus to the signaling traffic. A significant impact on analytical performance evaluations of mobile communication systems can be observed.

<title>Time/wavelength coding for diffuse infrared communication systems with multiple optical carriers</title>

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (1996)

K. Iversen Stefan Wolf Thomas Kuhwald E. Jugl Jens Mueckenheim

We propose two possibilities to combine multiple optical wavelengths with code division multiple access (CDMA) to achieve asynchronous access in diffuse IR-systems. A serial coding type which combines D-ary wavelength-shift keying with incoherent CDMA and a parallel coding type where the channels are distinguished by time/wavelength-matrices are investigated. We analyze the theoretical performance and show numerical results for different code families.

Performance evaluation of dynamic data rate adaptation on the UMTS dedicated channel

E. Jugl

We show the performance of packet data transmission on the UMTS dedicated channel (DCH). For that purpose, a framework of rate adaptation procedures has been developed. It significantly improves the performance in terms of decreased outage and lower transmission delay compared to simple algorithms which do not have the possibility of changing the rate. Furthermore, we show how the impact on the TCP/IP performance can be kept low.
