Title: Anu Virtanen: Innovator in Communication Technologies

Introduction

Anu Virtanen is a prominent inventor based in Espoo, Finland. She has made significant contributions to the field of communication technologies, holding a total of 9 patents. Her work focuses on enhancing communication protocols and data mapping techniques, which are crucial for modern mobile and wireless systems.

Latest Patents

Among her latest patents is a method and apparatus for transport format signaling with HARQ. This invention provides a method for signaling in a communication link using the hybrid automatic repeat request (HARQ) protocol. The signaling includes a predetermined bit pattern that indicates whether control information in the current transmission can be used alone for decoding or if additional control information from an earlier transmission is required. The basic idea is to inform the receiving node with a single bit, known as the 'TFCI flag', which indicates the usability of the TFCI bits for decoding the transport channel.

Another notable patent involves the mapping of internet protocol (IP) based data. This method facilitates the mapping of IP-based data and signaling data to form a single connection between mobile handsets in a code division multiple access (CDMA) system. It utilizes multiple sets of physical channels, ensuring that each channel maintains the same spreading factor, thereby optimizing data transmission.
