ATIS Activities on IMT Standards Asok Chatterjee Vice President, Industry Relations, Ericsson Global Standards Collaboration (GSC) GSC-15
ATIS interfaces with ITU-R directly as a Sector Member. The primary ATIS committee addressing IMT is the Wireless Technologies and Systems Committee (WTSC). The Radio Interface activities for IMT are handled by the RAN subcommittee of WTSC (WTSC-RAN). Core Network activities for IMT are handled by the G3GSN subcommittee of WTSC (WTSC-G3GSN). ATIS transposes 3GPP specifications for three IMT-2000 Radio interfaces in ITU-R Rec. M.1457: CDMA-DS, CDMA-TDD, and TDMA-SC. A large number of the member companies of WTSC are working on the IMT issues through 3GPP as well as through ATIS Sector Member input. Highlight of Current Activities (1)
ATIS, as a 3GPP Organizational Partner (OP), is part of “the proponent” for and endorsed the 3GPP LTE-Advanced IMT-Advanced submission to ITU-R WP5D. ATIS WTSC Registered as an ITU-R WP5D Independent Evaluation Group. Evaluated both IMT-Advanced submissions (ADV/4 and ADV/8). Conducted its IMT-Advanced evaluation activities in WTSC-RAN in a series of extra interim meetings in addition to the regularly scheduled WTSC meetings. Participated in the IMT-Advanced Evaluation Correspondence Fora in WP5D, both asking questions and obtaining responses. Participated in both IMT-Advanced proposal Workshops. Highlight of Current Activities (2)
ATIS submitted interim and final IMT-Advanced evaluation reports and concluded that there were no areas where the proponents failed to meet the requirements. ATIS continues to discuss WP5D IMT activities, as well as WP5A activities on Broadband Wireless Access (which includes IMT technologies), and produce input contributions as a Sector Member. ATIS intends to participate in the development of the IMT.UPDATE report on the future growth of Broadband Wireless and its spectrum requirements. Highlight of Current Activities (3)
Next Steps/Actions • ATIS will: • Continue to support the evolution of IMT-Advanced technologies, • Be a Global Core Specification (GCS) proponent in support of M.[RSPEC], • Be authorized as a “Transposing Organization” under the IMT-Advanced RSPEC process for the 3GPP LTE-Advanced proposal, • Transpose 3GPP specifications in support of ITU-R IMT-2000 and IMT-Advanced (M.1457, M.[RSPEC]) and ITU-T (Q.1741) activities, and • Contribute to the development of the IMT Handbook in ITU-R WP5D.
Proposed Resolution No changes proposed to existing Resolution (GSC-14/1) at this time.
ATIS WTSC along with TIA TR-45.3 submitted the GCS and update package for TDMA-SC toward M.1457-10 to ITU-R WP5D. ATIS as OP of 3GPP submitted its letter of conveyance for CDMA-DS and CDMA-TDD toward M.1457-10 to ITU-R WP5D. ATIS as OP proponent of 3GPP IMT-Advanced submission provided its endorsement to ITU-R WP5D. ATIS WTSC, as a registered Independent Evaluation Group, submitted interim and final IMT-Advanced evaluation reports on both IMT-Advanced proposals. ATIS WTSC Evaluation Group actively participated in IMT-Advanced evaluation ITU-R Correspondence Groups and workshops/coordination meetings. ATIS intends to be identified as a GCS Proponent and Transposing Organization for IMT-Advanced LTE-Advanced Radio Interface. Recent Activities on IMT in ATIS (for IMT Task Force Report)
