1. A wireless communication system, comprising:
at least a first base station,
a second base station of the same type as the first base station,
a plurality of mobile stations, each mobile station being configured to establish a latency-critical service with the first base station, and
a contention-based multiple access uplink channel without prior reservation of resources, the uplink channel comprising a plurality of resources,
wherein:
the communication system is configured such that each mobile station is associated with a specific sequence, each sequence defining a portion of the plurality of resources of the uplink channel,
each mobile station is further configured to transmit, to the first base station, a plurality of copies of a data packet according to the associated sequence, and
the first base station is configured to decode, for each mobile station, at least one resource according to the associated sequence,
wherein:
the first base station is further configured to:
determine the associated sequence for each mobile station, and
transmit the associated sequence to each mobile station,
each mobile station is further configured to receive, originating from the first base station, the associated sequence,
the system is further configured such that, during a transfer of the uplink channel between the first base station and the second base station, for at least one mobile station, the first base station is further configured to transmit the associated sequence of the mobile station to the second base station.
