METHOD FOR REDUCING POWER CONSUMPTION WHEN RECEIVING PAGING CHANNEL INFORMATION AT A MOBILE COMMUNICATION DEVICE

A mobile communication device (100) includes a receiver (102) which is normally shut off when the mobile communication device is idle. Upon the arrival of a paging time slot to which the mobile communication device is assigned, the mobile communication device turns on the receiver and begins receivi...

Summary:A mobile communication device (100) includes a receiver (102) which is normally shut off when the mobile communication device is idle. Upon the arrival of a paging time slot to which the mobile communication device is assigned, the mobile communication device turns on the receiver and begins receiving a composite signal including frequency diverse subchannels. The mobile communication device measures the delay spread of the subchannels (406). The receiver then adjusts the receiver on time for the next time slot based on the delay spread of the present time slot. L'invention concerne un appareil de communication mobile (100) comportant un récepteur (102) normalement coupé lorsque l'appareil de communication mobile est à l'état de repos. Lors de l'arrivée d'une fenêtre temporelle de radiomessagerie à laquelle l'appareil de communication mobile est affecté, l'appareil de communication mobile met le récepteur en marche et commence à recevoir un signal composite contenant des sous-canaux de diverses fréquences. L'appareil de communication mobile mesure l'étalement du temps de propagation des sous-canaux (406). Le récepteur règle ensuite le récepteur à temps pour la fenêtre temporelle consécutive sur la base de l'étalement du temps de propagation de la fenêtre temporelle courante.
