Abstract:
1. A method for a mobile terminal to transmit scheduling information to a network in a mobile communication system, the method comprising: receiving, during a transmission to the network of a first protocol data unit (PDU) of a medium access control (MAC) layer comprising first data received from an upper layer that is higher than the MAC layer, second data from the upper layer to be transmitted to the network with a higher priority than the first data, wherein the transmission of the first PDU is performed using a first hybrid automatic repeat request (HARQ) process associated with a first timing point on which the first PDU is transmitted; triggering scheduling information providing the network with information regarding an amount of data available for transmission in a buffer of the mobile terminal upon receiving the second data from the upper layer; generating a second PDU of the MAC layer comprising the triggered scheduling information; and transmitting the second PDU to the network using a second HARQ process associated with a second timing point on which the second PDU is transmitted, wherein the second timing point is different from the first timing point, and wherein the second timing point occurs before a third timing point on which feedback information regarding the first PDU is received, and wherein the second HARQ process allows the transmission of the second PDU before the feedback information regarding the first PDU is received.
