3GPP Work Item description

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

Feature:     UMTS 1,7/2,1 GHz

Additional spectrum was identified for IMT-2000 at WRC-2000, including the band 1710-1885 MHz. As a result of this decision the UMTS1800 work was concluded in TSG RAN (Rel-5). 

Subsequently, initiatives have been taken by one Administration in Region 2 to allow band pairing between 1710 MHz UL and 2110 MHz DL. It is expected that other Administrations will follow. 3GPP specified the band 2110-2170 MHz in its original R99 activity, and is also well suited for using with 1710-1770 MHz as uplink. Rapid specification work in 3GPP will allow for a timely global WCDMA arrangement so that the entire 2x60 MHz paired spectrum bands 1710-1770 and 2110-2170 MHz or parts of these bands may also be used with a consistent 400 MHz frequency separation between the uplink and the downlink.

While working with UMTS 1,7/2,1 GHz, 3GPP TSG RAN WG4 should consider information made available by FCC and Committee T1 (T1P1) concerning band plans, and ITU Region 2 implementation issues which may consider this new frequency allocation in North America. 

The objectives of this work item are:

• To generate necessary information for 1,7/2,1 GHz FDD system for potential deployment only in ITU Region 2 detailed below:

• Generate a report summarizing a study of radio requirements UTRA FDD in the 1.7/2.1 GHz Band 

1710 – 1770 MHz: Up-link (UE transmit, Node B receive)
2110 – 2170 MHz: Down-link (Node B transmit, UE receive)

Note  that this WRC 1,7/2,1 GHz band includes the current FCC band allocation given below for information:

• 1710 – 1755 MHz: Up-link (UE transmit, Node B receive)

• 2110 – 2155 MHz: Down-link (Node B transmit, UE receive)
  

This report, while considering the radio requirements for UTRA FDD in the 1,7/2,1 GHz band, shall investigate the need for two sets of Node B requirements:

• full band; and 

• restricted FCC bands given above.

and shall consider the use of UEs operating over 2 x 60 MHz in North America with possible interferance in 1755- 1770 MHz and 2155-2170 MHz.

Work to be led  by R4.
