Latest Patents

Sosnin's innovations include two significant patents that aim to streamline the random access channel (RACH) processes. The first patent, titled **"Mapping between PRACH preambles and PUSCH resource units for 2-step RACH,"** outlines a method for improving the traditional 4-step RACH procedure by implementing a more efficient 2-step RACH process. This advancement involves the transmission of a Physical Random Access Channel (PRACH) preamble and the associated MsgA physical uplink shared channel (PUSCH) on predefined time and frequency resources. The second step of the process involves the gNB transmitting MsgB upon successful detection and decoding of the PRACH preamble.

The second patent, known as **"Fallback procedure for 2-step RACH,"** discusses the mechanisms for a fallback option during a 2-step RACH procedure for data transmission. This patent describes the generation and transmission of a first signal by user equipment (UE) followed by a decision-making process to determine if a 4-step RACH procedure is necessary. If required, the UE can efficiently transmit data by utilizing the 4-step procedure.
