According to the invention data in a number of logical downlink channels (PCCH, CCCH, BCCH, CTCH, MCCH, MSCH and MTCH) intended for one or more mobile terminals are received in a first mapping unit (10), where at least a first High Speed Radio Network Temporary identity is allocated to these logical downlink channels addressing a group of mobile terminals for allowing transmission of channel data for reception by mobile terminals. A mobile terminal then reads, from a Broadcast Control Channel, necessary information including a High Speed Radio Network Temporary identity allocated to at least one logical downlink channel, where at least said first identity exists among possible identities. It then listens to a high speed shared control channel for the read identity. In case it detects the identity, the terminal follows a scheduling command, receives data on a high-speed downlink shared channel (HS-DCH) and processes said data.
