Abstract
An approach is provided for utilizing implicit negative acknowledgement. A determination is made that a user equipment is out of synchronization (e.g., with respect to the uplink). A control signal specifying timing alignment information is generated for transmission to the user equipment. An implicit negative acknowledgement corresponding to retransmission of data is declared if an acknowledgement is not received within a predetermined time interval.
