3GPP Work Item description

This page contains informal descriptive text only.  See master WID page for further details.

Feature:     UMTS-850

WRC 2000 extended the current IMT-2000 frequency allocation to include bands (currently occupied by other services) within the 850 MHz band. In particular, ITU-R Working Party 8F has initiated a revision to ITU-R Recommendation M.1036-1. This revision includes recognition of the WRC 2000 bands identified for IMT-2000, in particular the band range 806-960 MHz.

It is believed that GPRS/EDGE at 850 MHz will evolve into UMTS at 850 MHz in the 2007 – 2008 time frame within ITU Region 2. This band is currently occupied by a variety of technologies so studies of migration paths of the likely combinations of technologies should be considered (both internal and external to 3GPP). While progressing the specification work for UMTS-850, 3GPP should consider studies performed by and recommendations given by Committee T1 (T1P1) concerning band plans, interference, and ITU Region 2 implementation issues. 

It is suggested that the changes to incorporate UMTS in the 1900 MHz band could be used as the basis for this work which would reduce the effort required within 3GPP. 

The purpose of this work item is to generate necessary information of the 850 MHz FDD system for potential deployment in ITU Region 2 only:

• Generate a report summarizing a study of UTRA FDD in the 850 band (as described below) which includes the migration to UMTS-850 of the following technologies: GPRS/EDGE, TIA/EIA-136, TIA/EIA/IS-95, and Analog AMPS.  The specific bands to be studied are These uplink/downlink parings are consistent with the revision of ITU-R M.1036-1:
      824 – 849 MHz: Up-link (UE transmit, Node B receive)
      869 – 894 MHz: Down-link (Node B transmit, UE receive).

• Appropriate changes to existing specifications.

Work to be accomplished by R4 and possibly R4 and R4
