Abstract:
The present invention concerns a method for determining, in a wireless cellular telecommunication network, if a base station can not handle a half-duplex terminal, the base station transferring signals in a cell of the base station, the half-duplex terminal, when being handled by the base station, not transferring and not receiving signals during a period of time, called idle period of the cell of the base station. The base station: transfers signals in the cell of the base station, receives a signal transferred by the half-duplex terminal in response to a signal transferred by the base station, determines from the received signal, a characteristic of the half-duplex terminal in the cell, determines that the base station can not handle the half-duplex terminal if the characteristic of the half-duplex terminal in the cell is not compatible with the idle period.

Abstract:
Methods and apparatus for transmitting and receiving data having a data stream in a wireless broadcast system are provided. A frame is generated. The frame includes preamble section and a data section. The data section carries the data stream. The preamble section carries signalling information. The frame is transmitted to a receiver. In generating the frame, the data section of the frame is segmented into a plurality of frequency zones, and the data stream is mapped to a frequency zone of the plurality of frequency zones. The signalling information includes segmentation information of the frequency zones.
Abstract:
The present invention concerns a method for determining a corrected estimated variance representative of the condition of reception of signals representative of symbols transferred by an emitter to a receiver through a communication channel, wherein the method comprises the step, executed by the receiver, of producing an estimation of the variance by a Wiener channel estimator comprising a linear filter of which coefficients are determined at least from a given average signal to interference plus noise ratio value, the method being characterised in that it comprises farther step, executed by the receiver, of: multiplying the estimation of the variance by a correction factor, the value of the correcting factor being dependent at least on the number of coefficients of the linear filter of the Wiener channel estimator.
