Abstract
A method for a user equipment (UE) to generate a transmission is provided. In this method, a UE starts a time alignment timer when a time alignment command is received. The UE receives an uplink grant; and generates an initial transmission or a retransmission according to the uplink grant only when the time alignment timer is running upon receiving the uplink grant. In addition, the uplink grant is received through a Physical Downlink Control Channel (PDCCH) indicated by a Cell Radio Network Temporary Identifier (C-RNTI) of the UE.
