Abstract
Apparatus and method for determining the activation status of a receiving station of a communication system. A sending station determines the activation status of the receiving station to be active, possibly inactive, or inactive. When the receiving station is only temporarily unable to receive signals transmitted thereto by the sending station, the sending station is less likely to determine the receiving station to be inactive as the receiving station is first determined to be possibly inactive.
