(51)  International  Classification   H04L12/56 (2006.01)    H04L12/28 (2006.01)

(54)    Title

Fixed HS-DSCH or E-DCH allocation for voip (or HS-DSCH without HS-SCCH/E-DCH without E -DPCCH)

(57)    Abstract

In order to reduce the HS -SCCH overhead, a fixed time allocation approach could be used. In that case, the scheduling time of each VoIP user is semi-static and thus there is no need to transmit e.g. HS-SCCH toward the UE for the initial transmissions, if the UE knows when to receive data on the HS-DSCH and what transport format is used. There are at least two ways of implementing this: 1) HS- SCCH/E-DPCCH signalling to indicate parameters of a first transmission, with subsequent transmissions using the same parameters (and HS-SCCH/E-DPCCH always sent when changes needed), or

2)    fixed allocation, RRC signalling used to allocate users and tell the default transport parameters
