METHOD OF AN UPLINK HARQ OPERATION AT AN EXPIRY OF TIME ALIGNMENT TIMER |
摘要 |
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. |

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