Standardization of radio access network architecture and radio interface protocols for mobile communication systems

Anil Umesh

Anil UmeshMr. Anil Umesh has engaged in the establishment of standard specifications of network architectures and radio interface protocols, mainly in the 3rd Generation Partnership Project (3GPP), for 3.5th generation (High-Speed Packet Access (HSPA)), 4th generation (Long Term Evolution (LTE) and LTE-Advanced), and 5th generation (5G) mobile phone systems, and has made great contributions to the development and practical realization of mobile phone systems.
Through the above activities, Mr. Umesh has made numerous technical proposals to establish 3GPP standard specifications and has acquired numerous standard essential patents as an inventor. In the 3GPP Working Groups, he has been appointed as a coordinator (editor and rapporteur) on behalf of delegates of telecommunications carriers and vendors from around the world, and has demonstrated leadership in completing specifications. For 3.5th generation mobile phone system (HSPA), providing data communication services typified by the Internet connection at higher data rates was a major challenge. To overcome this challenge, Mr. Umesh made a number of technical proposals for the 3GPP standard specifications specifying radio interface protocols (TS25.309, TS25. 321, etc.) and completed the standard specifications in cooperation with major companies. In the examination of architectures for the radio access network (RAN) of 4th generation mobile phone systems (LTE/LTE-Advanced), he proposed the abolishment of the aggregation control node called RNC (Radio Network Controller), which was adopted in 3rd generation mobile phone systems, and moved the functions held by RNCs to base stations. This proposal was adopted in a 3GPP standard specification (TS 36.300), thereby realizing low latency mobile phone communications and enabling the introduction of new services with stringent requirements for latency. In the most recent standardization of 5G, he has been vigorously pursuing the standardization of interface specifications which enable the interconnection of aggregated nodes (CU: Centralized Unit) and distributed nodes (DU: Distributed Unit) from different vendors in the configuration of base stations. For this purpose, he has expanded his activities to other standardization bodies (xRAN and ORAN Alliance) beyond 3GPP. In the ORAN Alliance, he co-chairs a Working Group.
The series of standardization activities that Mr. Umesh has carried out have all been indispensable for the development and practical realization of mobile phone systems. I have high expectations regarding his performance looking into the future.
