Method and system for determining an interval of frequencies in a telecommunications network

A user equipment for determining an interval of frequencies of transmission, by said user equipment, of a signal to be sent to a base station in a telecommunications network, said interval of frequencies lying in a predetermined frequency band on which said base station operates and on which the user equipment is configured to transmit signals, the user equipment comprising:

• a memory for storing a table of references comprising values of reduction of maximum power of transmission of a signal by the user equipment such that a power of the signal transmitted by the user equipment at a predetermined off-band frequency is less than a predetermined maximum limit value of power, the user equipment being configured to determine the interval of frequencies from the table of references, said interval of frequencies enabling a transmission with a minimum attenuation of power, and
• a transmitter configured to transmit the signal in the interval of frequencies.

A method for transmitting, by a user equipment, a signal to a base station in a telecommunication network, said method comprising:

• determining an interval of frequencies of transmission of the signal to be sent to the base station, said interval of frequencies lying in a predetermined frequency band on which the base station operates, said interval of frequencies based on a table of references comprising values of reduction of maximum power of transmission of a signal by the user equipment such that a power of the signal transmitted by the user equipment at a predefined off-band frequency is less than a predetermined maximum limit value of power, said interval of frequencies enabling transmission without attenuating a power of a signal transmitted at said interval,
• wherein the determining is performed by the user equipment, and
• transmitting said signal by the user equipment to said base station in said interval of frequencies.
