Technical standards authority, the 3GPP2, said Wednesday it has completed a Technology Evolution Framework (TEF) outlining the evolution of cdma2000 beyond 2010 with regards to end to end system capabilities.

The framework is based on projected advances in wireless and networking technologies over the next decade, including the evolution of mobile devices, improvements in the radio air interface to carry native IP packets at ever increasing data speeds, and enabling full mobility voice and data communications across heterogeneous and constantly changing radio access network types.

3GPP2 technical specification groups are already evaluating different techniques to build on existing capabilities to further increase spectral efficiencies, data throughput and service-delivery capability.

At present, the 3GPP2 is working with the CDMA Development Group (CDG) on the next air interface evolution of cdma2000 known as Revision C, or EV-DOrC.

At the 3GPP2 meeting in Montreal earlier this month, the working group that was chartered by Technical Specification Group C (TSG-C) reached an agreement on defining a common framework for Frequency Division Duplexing (FDD) operations. This common framework agreement was based upon a consolidated proposal submitted by China Unicom, Huawei, KDDI, LG Electronics, Lucent Technologies, Motorola, Nortel, Qualcomm, RITT, Samsung, and ZTE.

The framework employs Orthogonal Frequency Division Multiple Access (OFDMA) on the forward link and supports several antenna techniques including Multiple Input Multiple Output (MIMO) and Spatial Division Multiple Access (SDMA). The reverse link employs quasi-orthogonal transmissions based on OFDMA, together with non-orthogonal user multiplexing with layered superposed OFDMA (LS-OFDMA). The reverse link also supports Code Division Multiple Access (CDMA) transmissions for control and for low-rate, low-latency traffic.

Detailed technical specifications are expected to be completed by early in the second quarter of 2007.

According to the Systems Requirement Document from the authority, using scalable bandwidths up to 20MHz, the forward link and reverse link peak data rates should be capable of up to 500Mbps and 150Mbps in a stationary indoor environment, and up to 100Mbps and 50 Mbps in a mobile environment, respectively.
