Feature:     DS-CDMA introduction in the 800 MHz band

Spectrum for IMT-2000 was first identified at WARC-92, and additional spectrum was allocated at WRC-2000, in particular 806 to 960 MHz.  That band is currently used in Japan for various mobile services.  A rationalization of those services is currently being examined by the national telecommunication council, and it is likely that this band could be used for IMT-2000 in the near future.

The objectives of this work item are:

• Study of DS-CDMA in the 800 MHz band (as described below) for a potential deployment only in Japan. To include co-existing studies with the following technologies: ARIB STD-27(PDC), ARIB STD-T53(IS-95), and ARIB STD-T64 (cdma 2000), taking the frequency reframing plan in Japan into account. Generate a new technical report based on study results

• The specific bands to be studied are (these uplink / downlink parings are consistent with the revision of ITU-R M.[1036-1]):

[810 – 855] MHz: Up-link (UE transmit, Node B receive)
[855 – 900] MHz: Down-link (Node B transmit, UE receive)

Work to be accomplished by R4, with R2 studying signalling issues and R3 studying interface aspects.
