The invention relates to a method for transmitting in a wireless network comprising a plurality of base stations, that transmit frames at a same frequency, and at least one mobile terminal. In order to optimise the size of a frame header, the method comprises: transmission, by a first set comprising at least two base stations, of at least a first part of the frame header on a same first physical channel comprising at least a first temporal interval, transmission, by at least a second set comprising at least one base station, of at least one second part of the frame header on a second physical channel comprising at least one second temporal interval different to the first temporal interval, the at least one second set being different from, but included in, the first set. The invention also relates to the corresponding method for reception.
