Title: WIRELESS COMMUNICATION SYSTEM COMPRISING A PHYSICAL CHANNEL FOR OVERALL RANDOM ACCESS IN TIME AND SPACE
Abstract:
The present invention relates to a wireless communication system (10) comprising a cellular access network (31) connected to a cellular network core (30), said cellular access network comprising cellular base stations (310) adapted to exchange data with terminals (20) on physical channels, called coordinated access channels, each cellular base station (310) serving a geographical area, all the geographical areas served by said cellular base stations forming a geographical region. The wireless communication system (10) comprises random access base stations (320) serving the geographical region, each random access base station (320) being adapted to receive data emitted by terminals on a permanent physical channel, called random access channel, the permanent physical random access channels of said random access base stations using the same radio resources throughout the geographical region.
