Methods and apparatus are provided for communication between a User Equipment (UE) and a Node B in a communication system by receiving a control signal including a resource allocation type, a resource allocation and a Modulation and Coding Scheme (MCS) from the Node B, and transmitting data based on the control signal to the Node B. The resource allocation type indicate that the resource allocation allocates a first set of at least one contiguous resource block or the resource allocation allocates second sets of resource blocks, and each of the second sets include one or more consecutive resource block groups.
