Reducing CQI Signalling Overhead in HSPA

Reducing CQI Signalling Overhead in HSPA

The efficiency of adaptive modulation and coding (AMC) procedure in high speed Downlink packet access (HSDPA) depends on the frequency of the channel quality information (CQI) reports transmitted by the UE to Node B. The more frequent the reports are the more accurate the link adaptation procedure is. On the other hand, the frequent CQI reports increase uplink interference, reducing thus the si...

Reducing the Adaptation Overhead

Déjà Vu is a case-based software design system whose success is based on two novel techniques: hierarchical case-based reasoning and adaptation-guided retrieval. Hierarchical case-based reasoning (HCBR) solves complex problems in a hierarchical fashion by reusing and combining the solutions of many separate cases and is fully supported by the normal CBR retrieve-and-adapt cycle. Adaptation-guid...

On Reducing Overhead in Loops

In this paper we discuss several techniques for reducing the overhead in Fortran-like DO loops. In particular, we describe two topics: 1. Simplifying loop bounds. 2. Removing a ne IF-statements from loops. The objective is to isolate the part of the iteration space of the original loop in which the bounds take simpler forms, or in which the condition is satis ed. The main technical tool for det...

Mobility Management Algorithms for Reducing Signalling Overhead in Next Generation Mobile Networks

Reducing Data Copying Overhead in Web Servers

Web servers that generate dynamic content are widely used in the development of Internet applications. With the Internet highly connected to people’s lifestyles, the service requirements of Internet applications have increased significantly. This increasing trend intensifies the need to improve server performance in dynamic content generation. In this thesis, we describe the opportunity to impr...
