Method for transmitting a message comprising information relating to the reception of data by a piece of receiving equipment belonging to a broadcast group, corresponding devices and computer programs

A method of communication between transmission equipment and at least one receiving equipment, both of which belonging to a broadcast group, the communication method being implemented by the transmission equipment and comprising:

• receiving a first message comprising at least a first set of information on generation of the message, by the receiving equipment, comprising information on reception of data, the first message being transmitted by a base station in a radio communication network to which all the equipments belonging to the broadcast group are connected, wherein the information on the generation of the message comprising information on the reception of data further comprises a complex-valued mathematical sequence which, when the sequence is applied to the radio signal to be used to transmit the message comprising information on the reception of data broadcast by the transmission equipment, modifies the amplitude of the radio signal to make it constant;
• broadcasting a second message, intended for the receiving equipment of the broadcast group, comprising a second set of information on the generation, by the receiving equipment, of the message comprising information on the reception of data, and at least one parameter pertaining to data to be broadcast by the transmission equipment;
• and
• receiving at least one message transmitted by at least one receiving equipment comprising information on an error having occurred during the reception of data broadcast by the transmission equipment.

Receiving equipment capable of transmitting a message comprising information on reception of data and belonging to a broadcast group comprising a plurality of receiving equipments and a transmission equipment, the receiving equipment comprising at least a hardware processor configured to:

• receive a first message comprising at least a first set of information on generation of the message, by the receiving equipment, comprising information on the reception of data, the first message being transmitted by a base station in a radio communication network to which all the equipments belonging to the broadcast group are connected, wherein the information on the generation of the message comprising information on the reception of data further comprises a complex-valued mathematical sequence which, when the sequence is applied to the radio signal to be used to transmit the message comprising information on the reception of data broadcast by the transmission equipment, modifies the amplitude of the radio signal to make it constant;
• receive a second message, broadcast by the transmission equipment, comprising a second set of information on the generation, by the receiving equipment, of the message comprising information on the reception of data, and at least one parameter pertaining to data to be broadcast by the transmission equipment;
• and
• transmit the message comprising information on an error having occurred during the reception of data broadcast by the transmission equipment.
