Introduction

Olivier Isnard is a notable inventor based in Viroflay, France. He has made significant contributions to the field of wireless communication, holding a total of 3 patents. His work focuses on enhancing the performance and reliability of radio links in wireless transmission systems.

Latest Patents

One of Isnard's latest patents is a procedure to determine radio link conditions using radio link control layer observations. This innovative method allows for the control of the performance of a radio link between a base transceiver station and a radio terminal. The radio network controller (RNC) monitors a directly observable L-parameter and determines a threshold violation without explicit L-L signaling. This triggers a status change of the radio link, enabling actions such as downgrading or upgrading the transmission rate or reconfiguring the radio link. The L-parameter may include the radio block error rate and the PDU retransmission rate.

Another significant patent involves a method for controlling data retransmission and a control unit for implementing this method. In this invention, frames exchanged between a control unit and a radio terminal are encapsulated with timestamping information. This information indicates the instant of transmission and reception of data frames, allowing for selective retransmission based on the acknowledgment frames received.
