IDCC correctly anticipated the increased responsibilities of the node-b. This was taken from a patent issued to IDCC last year.
That patent was filed in 2004.

Wireless communication method and apparatus with reconfigurable architecture for supporting an enhanced uplink soft handover operation
(This could be a very important patent for IDCC - revlis)
Methods for improving uplink coverage, throughput and transmission latency are currently being investigated in third generation partnership project (3GPP) in the context of the Release 6 (R6) universal mobile telecommunications system (UMTS) study item "FDD uplink enhancements".
It is widely anticipated that in order to achieve these goals, Node-B (base station) will take over the responsibility of scheduling and assigning uplink resources (physical channels) to users. The principle is that Node-B can make more efficient decisions and manage uplink radio resources on a short-term basis better than the RNC, even if the RNC retains coarse overall control. A similar approach has already been adopted in the downlink for Release 5 (R5) high speed downlink packet access (HSDPA) in both UMTS frequency division duplex (FDD) and time division duplex (TDD) modes.
It is also envisioned that there could be several independent uplink transmissions processed between a wireless transmit/receive unit (WTRU) and a universal terrestrial radio access network (UTRAN) within a common time interval.
