Method and apparatus for improving a transmission using a configured resource in a wireless communication system

A User Equipment (UE), wherein an uplink grant is available for the UE in a TTI (Transmission Time Interval) and the UE does not have data available for transmission comprising:

• a control circuit;
• a processor installed in the control circuit;
• and
• a memory installed in the control circuit and operatively coupled to the processor;
• wherein the processor is configured to execute a program code stored in the memory to:
• determine whether to skip the uplink grant in the TTI according to whether a physical control information needs to be transmitted in the TTI or not.

A method of a UE (User Equipment), comprising:

• an uplink grant is available for the UE in a TTI (Transmission Time Interval), wherein the UE does not have data available for transmission;
• the UE transmits a physical control information on a data channel according to the uplink grant if the physical control information needs to be transmitted in the TTI;
• and
• the UE skips the uplink grant if the physical control information does not need to be transmitted in the TTI.
