Patent ID: 7620014

Claim:
A method of transmitting radio signals between a base station and mobile terminals, wherein signals transmitted from the base station to at least one of the mobile terminals are transmitted on a first frequency and signals transmitted from at least one of the mobile terminals to the base station are transmitted on a second frequency, the transmissions on the first and second frequencies being performed according to a frame structure comprising timeslots of like duration, wherein the first frequency carries a downlink logical traffic channel to at least one of the mobile terminals and the second frequency carries an uplink logical traffic channel from one of the mobile terminals, wherein the first frequency further carries a first downlink logical signaling channel to one of the mobile terminals during the transmission phase on the uplink logical traffic channel and a second downlink logical signaling channel to at least one of the mobile terminals during the reception phase on the downlink logical traffic channel, wherein the second frequency further carries a first uplink logical signaling channel from at least one of the mobile terminals during the reception phase on the downlink logical traffic channel and a second uplink logical signaling channel from one of the mobile terminals during the transmission phase on the uplink logical traffic channel, and wherein the first downlink and uplink logical signaling channels are each carried by a first timeslot of the frame structure, while the second downlink and uplink logical signaling channels are each carried by a second timeslot of the frame structure, distinct from said first timeslot.
