Methods, devices and software programs for adapting uplink signaling during multicasting

摘要

The invention relates to a method for adapting uplink signaling during multicasting, according to which the user devices of a multicast group receive a multicast message from a network control unit via a radio channel (PMcCH) in a downlink connection. Said radio channel is adapted with respect to its power by transmitting information in an uplink connection via a corresponding radio channel (UL-DPCCH). According to the invention, said radio channel (UL-DPCCH) is power-controlled via at least one associated common radio channel (DL-PMcCH) that is associated with one or more of the user devices by transmitting corresponding information in the downlink direction from the network control unit to the user devices. Said information is then processed by the receiving user devices to adapt the power of the respective associated radio channels (UL-DPCCH) in the uplink direction.
