Abstract:
1. A method for transmitting scheduling information in a mobile communication system, the method comprising: transmitting a medium access control protocol data unit (MAC PDU) comprising scheduling information; determining, when reception of the MAC PDU by a receiver has failed, whether the MAC PDU comprising the scheduling information was transmitted together with any data of a layer that is higher than a MAC layer, or whether the MAC PDU comprising the scheduling information was transmitted without any data of a layer that is higher than the MAC layer; ceasing the transmission of the MAC PDU comprising the scheduling information, in response to the determining step, when the MAC PDU is transmitted without any data of a layer higher than the MAC layer; and continuing the transmission of the MAC PDU comprising the scheduling information, in response to the determining step, when the MAC PDU is transmitted together with any data of a layer higher than the MAC layer, wherein the MAC PDU is transmitted through an Enhanced Dedicated Channel (E-DCH).
