Abstract:
1. A method of transmitting uplink control information by a Medium Access Control (MAC) layer of a User Equipment (UE) in a wireless communication system, the MAC layer comprising a first MAC sub-layer and at least a second MAC sub-layer, the method comprising: generating, by the at least a second MAC sub-layer, a MAC-e protocol data unit (PDU) and transmitting the MAC-e PDU to a network via an enhanced dedicated channel, wherein the MAC-e PDU includes only control information indicating an amount of resources required by the UE, wherein the MAC-e PDU is transmitted in connection with a specific enhanced transport format combination indicator (E-TFCI) value, wherein the first MAC sub-layer is a MAC-d sub-layer for handling a dedicated transport channel, wherein the at least a second MAC sub-layer is located below the first MAC sub-layer and is for handling the enhanced dedicated channel, wherein the specific E-TFCI value is transmitted via an enhanced dedicated physical control channel (E-DPCCH), and wherein the specific E-TFCI value indicates to the network that the control information is transmitted alone.
