    摘要: A radio terminal is organized to send a first access signal then, when it receives a positive acknowledgement from a base station, a second access signal, resources of the communication network being allocated to the radio terminal after receipt of the said second access signal at the base station. At a base station, the first access signal sent by a radio terminal is received and the communication service requested by the terminal is detected therein. In conditional manner, depending on the detected communication service, a receive power of the first access signal is measured, the measured receive power is compared with a threshold, and the transmission of a positive acknowledgement of the first access signal to the radio terminal is inhibited, when the measured receive power is greater than the said threshold.

    摘要: In order to acquire first subbands in at least a central band of a broad frequency band, in which subbands frames are transmitted by a base station (BSBB) of a broadband network (RBB) which is co-located with a network (RNB) having narrow subbands comprised in the broadband, a mobile (MBBB) which does not know the distribution of the subbands correlates subsequences of a generated reference signal with subsequences which are respectively detected in the subbands and compares correlation coefficients against a threshold. By knowing the distribution of the first subbands, the mobile is able to process the signalling transmitted by the base station, in order to access allocated resources, after a synchronisation phase.

    摘要: A transmission signal (S) resulting from modulation of a digital data signal by a modulation function dependent on time t, the data signal being formed of a series of bits (bk) each identified by its rank k and having a duration T, the transmission signal (S) consisting of a summation indexed to the rank k of the product of the complex constant j to the power k, of the modulation function (h(t−kT) and of an input signal. The input signal F(k) being a function of the data signal (bk), the modulation function h(t−kT) is a Gaussian function of time t.

    摘要: In certain circumstances, a mobile radiocommunication terminal estimates an initial radio signal transmission power, i.e. a random access request, to a base station located within the range thereof. If it is very close to said station, said initial estimated power can be lower, even greatly lower, than the minimum transmission power of the mobile terminal. In order to limit interference with other communications in progress, the transmission of said signals is inhibited if the difference between the minimum transmission power and the initial estimated power lies beyond a predefined threshold.
