摘要： The invention relates to the management of communications in a communication network (100) comprising at least one transmitting device (101) and at least one terminal (102) which is adapted to receive data. The inventive management method comprises the following steps: establishment (304, 309, 312) of a communication between one of the terminals, called the destination terminal, and one of the transmitting devices, called the transmitting device, using a first communication mode which is based on a single-carrier modulation; and passing to a second communication mode (307, 310) using a multicarrier modulation (OFDM), with a communication channel that uses the multicarrier modulation being assigned to the communication between the transmitting device and the destination terminal. According to the invention, said first and second communication modes are carried out successively in an alternating manner. The invention also relates to the corresponding signal, transmitting device and destination terminal.

摘要： A method is provided for extracting a sequence of pilot symbols enabling to estimate the transfer function of a transmission channel. At least a radiocommunication device communicates through the channel with a remote station, the latter regularly delivering to the radiocommunication device a reference pattern. The structure of the reference pattern is variable, depending on at least one characteristic of the transmission channel.

摘要： 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.

摘要： The cellular communications network has a large cell (100) with a base station (101) and a second smaller cell (120) with a second base station. The first base station drives the terminal when in standby mode when the terminal is present in the small cell, the second base station being able to take charge in the communication mode.

摘要： The invention concerns a method for estimating the transfer function of a multicarrier signal transmission channel (42) consisting of a temporal succession of symbols of a set of data elements, each of the data elements modulating a carrier frequency of the signal, the data elements comprising pilots and so-called informative data elements. The invention is characterised in that said method comprises: a step which consists in determining a set of two-dimensional discrete prolate spheroidal sequences (DPSS); a step which consists in writing (53) the transfer function in the form of a combination of at least some of the two-dimensional discrete prolate spheroidal sequences (DPSS); a step which consists in time-based and frequency-based two-dimensional interpolation (54) of at least some of the coefficients of the combination, so as to obtain an estimation of the transfer function at any point of a time-frequency network.

摘要： The terminal synchronization method between first (100) and second (120) cells associated with a first and second base station (101) has a common geographic zone. There is a first synchronization step on a synchronization signal transmitted by the first base station and received by the terminal. There is a second synchronization step on a predetermined signal dedicated to process multiple trajectories transmitted by the second base station and received by the terminal.
