Abstract

En fremgangsmåte for sending og et radiosystem omfatter minst en basestasjon (100) og et antall abonnentterminaler (201-203), hvor minst to av disse sender aksess-skurer til en og samme basestasjon. Aksess-skuren aktiverer en forbindelse mellom en abonnentterminal og en basestasjon som etableres ved hjelp av et signal som har en viss frekvens og sendes i tidsluker. Radiosystemet omfatter en sender- anordning (101) som beordrer abonnentterminalen til å sende til basestasjonen (100) et signal som anvender en tidsluke og frekvens som allerede brukes av en annen abonnentterminal. Radiosystemet omfatter videre en justeringsanordning (205) som på grunnlag av ordren som sendes fra senderanordningen (101), justerer sendetidspunktet for signalet som skal sendes til basestasjonen (101), slik at basestasjonen (101) mottar de sendte signalene på forskjellige tidspunkter.A method of transmission and a radio system comprises at least one base station (100) and a plurality of subscriber terminals (201-203), at least two of which transmit access bursts to one and the same base station. The access burst activates a connection between a subscriber terminal and a base station which is established by a signal having a certain frequency and transmitted in time slots. The radio system comprises a transmitter (101) which commands the subscriber terminal to transmit to the base station (100) a signal employing a time slot and frequency already used by another subscriber terminal. The radio system further comprises an adjusting device (205) which, on the basis of the order sent from the transmitting device (101), adjusts the transmission time of the signal to be sent to the base station (101), so that the base station (101) receives the transmitted signals at different times.
