Claim of US Patent No. 9,491,629

1. A method, in a cellular communication network comprising cells among which at least one cell is switched off, for providing
at least a minimum coverage for multimedia transmission, said multimedia being parted into a number of independent autonomous
multimedia partitions, comprising:
transmitting from one or more neighbor cells of said switched off cell, one or more multimedia partitions of a primary subset
of the one or more multimedia partitions over a normal range;

transmitting from at least a first and a second neighbor cell of said switched off cell, one or more multimedia partitions
of a secondary subset of the one or more multimedia partitions over an extended range, said secondary subset of said first
neighbor cell being totally disjoint from said primary subset of said first neighbor cell, the secondary subset of said first
neighbor cell being partially disjoint of the secondary subset of said second neighbor cell when said first cell and said
second cell are adjacent.
