Abstract
The invention relates to a method for transmission of data in a wireless network comprising a plurality of base stations broadcasting data at a same frequency and a plurality of mobile terminals. In order to overcome inter-cell transfer at the level of mobile terminals, the method comprises:
- assignments of first and second sub-sets of base stations at respectively at least a first and at least a second mobile terminal, the assignments varying in time according to first and second parameters, the two sub-sets having at least one base station in common and each at least having a specific base station,
- synchronized transmissions of respectively the base stations of the first and second sub-set of first and second specific data modulated with first and second modulations to respectively the at least first and second mobile terminals.
The invention also relates to the corresponding method for reception of data.
