Method and apparatus for transmitting and receiving scheduling assignments in a communication system

A User Equipment (UE) apparatus for receiving a Scheduling Assignment (SA) in a communication system in which a base station transmits the SA including at least one Information Element (IE), the UE apparatus comprising:

• a transceiver configured to receive the SA;
• a comparator configured to identify if a first IE included in the received SA is set with a first predetermined value and at least one bit in a second IE included in the received SA is set with a second predetermined value;
• and
• a controller configured to perform an action corresponding to a semi-persistent scheduling of the UE, if the first IE included in the received SA is set with the first predetermined value and the at least one bit in the second IE included in the received SA is set with the second predetermined value.
