Abstract  Abstract

A method of operating multiple time alignment timers (TimeAlignmentTimer) is provided for facilitating communication between and evolved Node B (eNB) and a User Equipment (UE) in a Long Term Evolution (LTE) system supporting multiple carriers. The method includes starting a first TAT of a first group including the primary cell starting a second TAT when Timing Advance (TA) information on a second group not including the primary cell; and determining transmission of at least one of a Hybrid Automatic Repeat Request Acknowledgement/Negative-acknowledgement (HARQ ACK/NACK) a physical uplink control channel and a sounding reference signal according to a start and an expiration of at least one of the first and second TATs.
