1. Data transmission method in a radio communication network comprising:
- at least one base station; and
at least one terminal adapted to individually and periodically transmit binary information on an uplink radio channel to at least one of the base stations called the first base station,wherein the method comprises;
transmitting at least one bit, called first binary information through the radio channel for controlling transmission power of the first base station; and
transmitting at least one bit, called second binary information through the radio channel designed to a purpose other than controlling the transmission power of the first base station,at least one of said first or second binary information being transmitted individually and periodically such that two consecutive binary information are never assigned to a purpose other than controlling the power of the first base station, andsaid second binary information being inserted among said first binary information.

Abstract
A cellular communication system is provided comprising a terminal, a base station (for example UMTS) and a communication equipment designed to transmit data to a terminal and which is not provided with an uplink channel (for example using an OFDM technique). By transmitting via the TCP channel data other than those for controlling the power of the receiver base station, the terminal can control the power of the OFDM system transmitting high speed data to the terminal, the OFDM system being coupled to the UMTS network with which the terminal communicates.

17. Terminal adapted to individually and periodically transmit binary information on an uplink radio channel to a base station called the first base station in a radio communication network, wherein the terminal is adapted to:
-
distinguish and insert among said binary information; at least one bit, called first binary information for controlling transmission power of the first base station; and at least one bit, called second binary information designed to a purpose other than the control of the power of the first base station, at least one of said first or second binary information being transmitted individually and periodically such that two consecutive binary information are never assigned to a purpose other than controlling the power of the first base station, and said second binary information being inserted among said first binary information.

18. A base station in a cellular network, adapted to individually and periodically receive binary information on an uplink radio channel from a terminal, wherein the base station is adapted to distinguish and extract among the said binary information:
-
at least one bit, called first binary information for controlling transmission power of the first base station; and at least one bit, called second binary information designed to a purpose other than controlling the power of the first base station, at least one of said first or second binary information being transmitted individually and periodically such that two consecutive binary information are never assigned to a purpose other than controlling the power of the first base station, and said second binary information being inserted among said first binary information.
