METHOD AND SYSTEM FOR DISTRIBUTION IN A MIXED POINT-TO-MULTIPOINT AND POINT-TO-POINT (D2D) NETWORK

The invention relates to a method and a system for transmitting contents to a set of users UEk in a wireless communication network characterized in that it allocates the radio resources by executing at least the following steps: Measuring or evaluating the quality of the radio linkups between the base station BS and the users UEk (201 ), and the quality of the D2D radio linkups between the various users UEk (202), Selecting, as a function of the information in respect of quality of linkups, one, and only one, subset of users MG i *, of cardinality greater than or equal to 1, and a modulation and coding scheme MCS to be used for the point-to-multipoint transmission performed by the base station so as to guarantee the capacity to decode such a transmission to all the users forming part of the selected subset MGi*, Generating a tree A (206), of cardinality greater than or equal to 0, formed exclusively by linkups UEk→UEk (D2D) existing between the users so as to relay the content of the point-to-multipoint transmission from the users forming part of the subset MG i * as chosen in the previous step towards all the others, Allocating radio resources on the D2D links defined by the tree A.
