Method and apparatus for scheduling uplink rates adaptively to fast rate ramping in a packet communication system

A Node B for transmitting uplink rate assignment information for an uplink data transmission to a User Equipment (UE) in a mobile communication system, comprising:

• a controller for determining the uplink rate assignment information to be transmitted for each UE, wherein the uplink rate assignment information is attached with a UE ID-specific Cyclic Redundancy Check (CRC) of the UE when directly indicating an uplink rate grant for the UE, and the uplink rate assignment information is transmitted without the UE ID-specific CRC to the UE when indicating an uplink rate change in states or an uplink rate maintain;
• and
• a transmitter for transmitting the uplink rate assignment information to the UE.

A method for transmitting uplink data to a Node B by a User Equipment (UE) in a mobile communication system, comprising the steps of:

• receiving uplink rate assignment information for an uplink data transmission from the Node B, wherein the uplink rate assignment information is attached with a UE ID-specific Cyclic Redundancy Check (CRC) of the UE when directly indicating an uplink rate grant for the UE, and the uplink rate assignment information is transmitted without the UE ID-specific CRC to the UE when indicating an uplink rate change in states or an uplink rate maintain;
• and
• transmitting the uplink data to a Node B based on the uplink rate assignment information.
