Abstract
The present invention provides a method for determining a need to retransmit a message that includes a user frame from a base station (,) in a communication system (,). A signaling message is inserted into the user frame. The user frame is transmitted from the base station (,) and received at a mobile unit (,). The mobile unit (,) transmits an erasure indicator bit to indicate that the user frame was received by the mobile unit (,). The base station (,) receives the erasure indicator bit. It is then determined, based at least in part upon the erasure indicator bit, whether the signaling message was accurately transmitted by the base station (,) and received by the mobile unit (,). If the signaling message was not accurately transmitted and received, the base station (,) will retrieve the stored signaling message and retransmit the signaling message to the mobile unit (,).
