LTE SAE Standardization Activities and Contributions for Completion of the 3GPP LTE/SAE Standard Specifications The 3GPP Release 8 standard specifications completed in Radio Access Network Development Department Takehiro Nakamura†1 March 2009 are a major advance beyond the previous Sadayuki Abeta †1 specifications. Since 2004, there has been progress in the Core Network Development Department Takashi Koshimizu†1 key standardization sets in both the radio access specifica- Katsutoshi Nishida †1 tions and the core network specifications, under the respec- Itsuma Tanaka †1 tive working item names of LTE and SAE. NTT DOCOMO RD Strategy Department Naoto Matoba †1 has been active in the technical proposals and providing input to the standard process from the beginning. We have contributed greatly through serving as important positions and other ways in both the plenary meetings and the WG meetings for finalizing specification sets. Eventually, the set of standard specifications required for LTE/SAE develop- ment were completed. Access (OFDMA) for the access of Rel. 8. The LTE and SAE standard- 1.
