Abstract
Methods for a wireless transceiver, the methods having corresponding apparatus and computer programs, comprise: transmitting a ranging sequence modulated according to a first modulation mode at a power level selected according to a normalized carrier-to-noise value associated with the first modulation mode as set forth in a table associating normalized carrier-to-noise values with modulation modes; transmitting a first ranging request message according to a second modulation mode at a power level selected according to a normalized carrier-to-noise value associated with the second modulation mode, the first ranging request message being transmitted after having received a ranging response message for the ranging sequence; and increasing each normalized carrier-to-noise value in the table, except the normalized carrier-to-noise value associated with the first modulation mode, by a predetermined amount in response to the transceiver not receiving a response to the first ranging request message within a predetermined interval.
