Abstract:
A method of processing data for a Hybrid Automatic Repeat reQuest (HARQ) operation in a wireless communication system. The method includes receiving a timing alignment command (TAC) and one or more uplink grants from a network; and generating a data unit. The one or more uplink grants are used for transmitting the generated data unit to the network. The method further includes starting a time alignment timer (TAT) upon receiving the TAC. The TAT is used to control how long a User Equipment (UE) is considered to have an uplink time that is aligned. The method further includes when the TAT expires, clearing the one or more uplink grants.
