A RADIO COMMUNICATION SYSTEM COMPRISING A PRIMARY STATION AND A PLURALITY OF SECONDARY STATIONS, AND A METHOD OF OPERATING SUCH A RADIO COMMUNICATION SYSTEM

摘要

The invention relates to a radio communication system in which secondary stations (110) can request services from a primary station (100) using a random access channel employing a time division multiple access protocol, An access request comprises an access packet (200) having a predetermined maximum data capacity. If a secondary station requires to transmit an access request including more payload data (202,206) than can be accommodated in a single access packet the data is subdivided into a plurality of parts each of which is transmitted in a separate access packet. The primary station combines the data from the plurality of access packets (200) forming the access request, and issues an acknowledgement to the secondary station.
