2148806 9507587 PCTABS00036 In a mobile radio telephone system employing TDMA or CDMA, mobile units (5, 7) often must determine the timing and approximate power necessary for transmissions to a base station. Information broadcast by base stations allows the mobile station to approximate its distance from each base station (1) based on an average signal strength received and thereby determine the coarse sector location. Broadcast information may include the mean radial distribution of signal strength versus distance. From the broadcast information, the mobile station (5, 7) determines the propagation loss for a transmission to the base station and the appropriate power level and timing for transmissions. Accordingly, the mobile station (5, 7) transmits signals to the base station (1) at the determined signal timing and power level.

Dans un système de radiotéléphone mobile dans lequel l'accès multiple à répartition dans le temps (TDMA) et l'accès multiple par différence de code (CDMA) sont utilisés, les unités mobiles (5, 7) doivent souvent déterminer la synchronisation et l'intensité approximative appropriées pour la transmission à une station de base. La diffusion d'informations par des stations de base permet à la station mobile d'évaluer la distance à laquelle celle-ci se trouve de chaque station de base (1) en fonction d'une intensité de signal moyenne reçue, et de déterminer ainsi l'emplacement approximatif du secteur. Les informations diffusées peuvent comprendre la répartition radiale moyenne de l'intensité du signal par rapport à la distance. A partir des informations diffusées, la station mobile (5, 7) détermine l'affaiblissement de propagation pour une transmission vers la station de base ainsi que le niveau d'intensité et la synchronisation appropriés pour les transmissions. Ainsi, la station mobile (5, 7) envoie des signaux à la station de base (1) selon la synchronisation et l'intensité déterminées.
