Abstract:
1. A method of performing data communication between a mobile station and a network, each having a medium access control (MAC) layer, the method comprising: mapping a dedicated control channel (DCCH), which is a logical channel, to at least two transport channels for a MAC layer protocol; mapping a dedicated traffic channel (DTCH), which is a logical channel, to said at least two transport channels for the MAC layer protocol; determining, during data reception mode, a logical channel based on logical channel type information contained in a header of a MAC protocol data unit (PDU) received from a transmitting side; and branching data included in the MAC PDU to a corresponding MAC service access point (SAP) based on the determined logical channel, wherein the determined logical channel is the DCCH or the DTCH, and wherein the DCCH and the DTCH, are located between a radio link control (RLC) layer and the MAC layer, and said at least two transport channels are located between the MAC layer and a physical layer.
