Radio resource management in HSDPA and HSUPA

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.

Emission Reduction and Capacity Increase in GSM Networks by Single Antenna Interference Cancellation

Summary There is an increasing demand to utilize the frequency spectrum of mobile communication systems most efficiently. This means in particular to GSM networks that the frequency reuse shall be planned as low as possible. In this case the system may become limited by interference rather than coverage. One promising technology for GSM mobiles in interference-limited systems is single antenna interference cancellation (SAIC). This receiver technology allows both for increasing the network capacity and for reducing the base station transmit power. The aim of this paper is to assess the emission reduction as well as the system capacity capabilities when SAIC technology is applied in downlink receivers.
