A wireless transmit receive unit and methods for code division multiple access telecommunications are disclosed that process data in a physical layer and a medium access control (MAC) layer. The physical and MAC layers communicate data between each other via transport channels. The transport channels are associated with logical channels. Logical-channel data for the transport channels is provided in data units having a bit size evenly divisible by an integer N. The respective logical channels associated with a transport channel utilize MAC headers that have a selected modulo N bit size such that there is bit alignment of the MAC headers of all the logical channels associated with a particular transport channel.
