ABSTRACT:
Apparatus, and an associated method, selectively transmits packets of message data between a sending and a receiving station. When a packet of message data is received at a receiving station, the receiving station acknowledges reception thereat of the packet with an acknowledgment response signal, transmitted back to the sending station. If the sending station fails to detect an acknowledgment response signal, a packet of activity-request data is sent to the receiving station. If the receiving station fails to acknowledge reception of the packet of activity-request data, a determination is made that the receiving station would be unlikely to be able to receive an additional packet of message data. A channel to be used to transmit the packet of message data can instead be reallocated for other purposes.
