Abstract:
A communication method in a communication system having a plurality of first transmission devices and a plurality of second transmission devices, the communication method being performed by each of the second transmission devices and comprising for a particular second transmission device of the plurality of second transmission devices:communicating with a selected first transmission device of the first transmission devices; intermittently receiving signals transmitted from the selected first transmission device or intermittently transmitting signals to the selected first transmission device; a first transmission step of transmitting signals to said selected first transmission device at a transmission rate R1; a suspension step of suspending signal transmissions to said selected first transmission device; a second transmission step of transmitting signals to said selected first transmission device at a transmission rate R2 higher than said transmission rate R1; and in said suspension step, monitoring the signal quality of radio channels that are different from the radio channel used by said first and second transmission steps, wherein said transmission rates R1 and R2 have the relationship R1 T1&lE;(R2âˆ’R1)T2, where T1 is the duration of said suspension step and T2 is the duration of said second transmission step.
