Abstract:
1. A communication device, comprising: a data transmission control unit configured to control transmission of data onto a communication channel and provide at least two radio resource control communication link states of the radio resource control protocol layer, wherein, when the data transmission control unit is in a first radio resource control communication link state, the data transmission control unit allocates the data to a first common communication channel or to a second common communication channel, wherein the first common communication channel or the second common communication channel is selected based on the amount of data to be transmitted, and wherein, when the data transmission control unit is in a second radio resource control communication link state, the data transmission control unit allocates the data to be transmitted to a third common communication channel; and a transmission unit configured to transmit the data via the common communication channel to which the data to be transmitted is allocated, wherein the common communication channels are common mobile radio transport channels, the first common communication channel is an enhanced uplink shared channel, the second common communication channel is a first random access channel, and the third communication channel is a second random access channel.
