Abstract
An integrated radio communication system with ordered hierarchical cellular coverage comprises a first system and a second system, the coverage of the second system covered by the coverage of the first system, and a set of dual-mode terminals that can selectively use the first system or the second system. The first and second systems are configured to simultaneously share a common portion Bc of a first band Bof frequencies respectively on a first uplink and a second uplink, and respectively manage first transmission resources and corresponding second transmission resources. The second radio communication system of lower level Nis free to manage its second transmission resources without any coordination constraint with respect to the first system of higher level Nwhereas the first system of higher level is configured to not disturb the second system in the common frequency band portion. The first system is configured to transmit data packets on a first uplink random access contention channel and to manage its first resources optimally in terms of transmission capacity of the channel as a function of the measurement of the occupancy of the second radio resources currently used by the second system and of the first resources currently used by the first system.
