Abstract
A method of operating a radio communication system in which secondary stations use dedicated time slots to request services from a primary station. A secondary station wishing to request a service sends a request in every time slot allocated to it until it receives an acknowledgement from the primary station. The primary station can use combining techniques on multiple time slots to identify the presence or absence of a request from a secondary station with improved accuracy.
