FIELD: physics, communications.
SUBSTANCE: invention relates to voice over IP (VoIP) transmission and other real time services for high-speed downlink packet access (HSDPA), high-speed packet access (HSUPA) in systems based on wide-band code division multiple access. A fixed time allocation approach can be used for a high-speed shared control channel (HS-SCCH). In this case the scheduled time for each user of the VoIP service is semi-static, and therefore there is no need to transmit service information, e.g. over a HS-SCCH to user equipment for initial transmission if the user equipment knows when to receive data over a HS-DSCH and which transportation format is used. There are at least two methods for realising this: 1) signalling over a HS-SCCH)/E-DPCCH to indicate first transmission parametres, with subsequent transmissions using the same parametres (and HS-SCCH/E-DPCCH is always transmitted when changes are required) or 2) fixed allocation, signalling the radio resource control (RRC) level is used to distribute users and communicating default transport parametres.
EFFECT: reduced amount of service information.
