determining for the NodeB a third parameter (wait) value indicative of a time period for the NodeB to wait before the HS-SCCH order will be transmitted to the UE.
11. The method of claim 1 , further comprising:
determining for the NodeB a parameter (pre-emption) adapted to identify priority levels of multiple UEs to selectively inhibit E-DCH transmission.
12. The method of claim 4 , wherein said steps of determining and transmitting a pair of first and second parameter values are repeated for each of a plurality of UE groups associated with said NodeB to correspondingly configure NodeB operation.
13. The method of claim 12 , wherein said UE groups are defined in terms of any of service level agreements (SLA), service provider, UE device capability, type of mobile service, type of traffic, priority of traffic, priority of traffic channel, and Random Access Channel (RACH) parameters.
14. The method of claim 4 , wherein said steps of determining and transmitting a pair of first and second parameter values are repeated for each UE within a subset of UEs associated with said NodeB to correspondingly configure NodeB operation.
15. The method of claim 4 , wherein said steps of determining and transmitting a pair of first and second parameter values are repeated for at least one logical channel used by each UE within said subset of UEs associated with said NodeB.

The method of claim 4 , wherein said pair of first and second parameter values transmitted towards the NodeB comprise suggested parameter values to correspondingly configure NodeB operation to adapt any of said first and second parameter values in response to information possessed by said NodeB.
18. The method of claim 4 , wherein said steps of determining and transmitting a pair of first and second parameter values are repeated for each of a plurality of UE group types associated with said plurality of NodeBs to correspondingly configure common NodeB operation for each UE group type, wherein said UE group types are defined in terms of any of service level agreements (SLA), service provider, UE device capability, type of mobile service, type of traffic, priority of traffic, priority of traffic channel, and Random Access Channel (RACH) parameters.
19. The method of claim 1 , wherein said first and second parameters are configured according to HS-DSCH priority queue information.
20. The method of claim 1 , wherein said first parameter is estimated using the following equation:
RepPeriod= M max* Nb 01max+margin
where:
Mmax is a maximum number of preamble cycles;
Nb01max is an upper bound for random backoff when a NACK to AICH is received; and
Margin is an amount of time associated with propagation delay and UE processing time.
