Title: Innovations of Siva Dharshan Muruganathan

Introduction

Siva Dharshan Muruganathan is a prominent inventor based in Kanata, Canada. He holds an impressive 192 patents that showcase his contributions to the field of wireless communication technologies. His work has significantly advanced the capabilities of mobile networks.

Latest Patents

Among his latest patents is the invention titled "PUSCH multiple TRP reliability with UL TCI indication." This patent describes systems and methods to support Physical Uplink Shared Channel (PUSCH) multi-Transmission/Reception Point (TRP) scheduling. In this invention, the wireless device can obtain a configuration for Transmission Configuration Indicator (TCI) states for Uplink (UL) PUSCH scheduling. It can activate or deactivate a subset of configured TCI states. If two TCI states are indicated, the wireless device transmits two different PUSCHs corresponding to each indicated TCI state. If only one TCI state is indicated, a single PUSCH is transmitted. The wireless device also maps indicated TCI states to transmission occasions based on preconfigured parameters or predefined rules. Additionally, the device applies a Transmitted Precoding Matrix Indicator (TPMI) to the transmission occasions associated with each indicated TCI state.

Another notable patent is "Multi-DCI based PDSCH scheduling for URLLC." This invention outlines systems and methods for multiple Downlink Control Information (DCI) based Physical Downlink Shared Channel (PDSCH) scheduling. The method involves a User Equipment (UE) receiving first and second Physical Downlink Control Channels (PDCCHs) carrying first and second DCIs in different Control Resource Sets (CORESETs) during specified time periods. The UE also receives first and second PDSCHs scheduled by the DCIs and sends HARQ ACK/NACKs in designated Physical Uplink Control Channel (PUCCH) resources.
