Title: Innovations by Chethan Venkatesan
Introduction
Chethan Venkatesan is a notable inventor based in Dresden, Germany. He has made significant contributions to the field of narrowband Internet of Things (NB-IoT) technology. With a total of 3 patents, his work focuses on improving the reliability and efficiency of communication in IoT devices.
Latest Patents
One of his latest patents is titled "Broadcast channel reception in NB-IoT devices." This invention presents a method for enhancing the reliability of a narrowband physical broadcast channel (NPBCH) reception during the cell acquisition phase in NB-IoT user equipment (UE). The method aims to improve the existing NPBCH reception procedure, achieving a lower code-rate for more reliable transmission between eNodeB and UEs. The UE receives, descrambles, and de-rate-matches at least a first and a second group of 64 NPBCH subframes, utilizing the four most significant bits of the system frame number as a counter and a modifier sequence. This innovative approach allows the UE to attach to the cell if a match is found.
Another significant patent is the "Method for predictive reception of physical layer downlink repetitions in a NB-IoT UE for prolonged battery lifetime." This disclosure outlines a method that extends the battery life of IoT devices by estimating the expected number of repeated sub-frames necessary for successful reception of downlink transmissions. The method employs a redundancy estimation function and a repetition reception control function, creating a feedback loop to refine and adapt the predictive reception process.
