Method for scheduling in mobile communication and apparatus thereof

A communication method, the method comprising:

• transmitting, by a terminal, a first message to a base station on an Uplink Shared Channel (UL-SCH), the first message including first information about an amount of first data available for transmission in a first buffer of the terminal and second information about an amount of second data available for transmission in a second buffer of the terminal, wherein the first buffer is associated with a first logical channel and the second buffer is associated with a second logical channel;
• receiving, by the terminal, a second message from the base station, the second message including third information about uplink resources;
• and
• transmitting, by the terminal, the first data to the base station using the uplink resources, wherein the first data is transmitted on the UL-SCH,
• wherein:
• the first information indicates that the first buffer is not empty and the second information indicates that the second buffer is empty, and
• the third information indicates location of the uplink resources.

A communication device, comprising:

• a circuitry configured to:
• cause the device to receive a first message from a terminal on an Uplink Shared Channel (UL-SCH), the first message including first information about an amount of first data available for transmission in a first buffer of the terminal and second information about an amount of second data available for transmission in a second buffer of the terminal, wherein the first buffer is associated with a first logical channel and the second buffer is associated with a second logical channel;
• allocate uplink resources based on the first information;
• cause the device to transmit a second message to the terminal, the second message including third information about the uplink resources;
• and
• cause the device to receive the first data from the terminal using the uplink resources,
• wherein the first data is received on the UL-SCH,
• the first information indicates that the first buffer is not empty and the second information indicates that the second buffer is empty, and
• wherein the third information indicates location of the uplink resources.
