1. A method of operating a radio communication system, comprising:
- allocating respective time slots in an uplink channel to a plurality of respective secondary stations; and
transmitting a respective request for services to establish required services from at least one of the respective secondary stations to a primary station in the respective time slots;
wherein the at least one respective secondary station re, transmits the same respective request in consecutive allocated time slots without waiting for an acknowledgement until said acknowledgement is received from the primary station, wherein the primary station determines whether a request has been transmitted by the at least one respective secondary station from a combination of the received signals in a plurality of successive time slots allocated to the at least one respective secondary station.

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.
