- Adjacent and non-adjacent 5 MHz carriers in a single band (e.g. 2.1 GHz)
- Use of several bands. Band combinations suggested: I and VIII (2.1 GHz + 900 MHz, Europe), II and IV (1900 + 1700, US), I and V (2.1 GHz, Europe + 850 US [???])
- MIMO support depending on the capabilities of the UE in a band. This is an interesting as with this sentence it is assumed that a future UE could support MIMO only in some of the bands it supports.
Nothings written into stone yet (eh, into the standards I mean) but this is where things are likely to go.
Oh, and I learnt of a new company name: Alcatel-Lucent Shanghai Bell. An interesting combination!
