  • Patent number: 10548119
    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.
