Abstract:
In a Time Division Multiple Access based radio telecommunications system that employs downlink power control, a method of measuring and reporting received signal strength information, said method comprising the steps of:transmitting a downlink data signal from a base station to a mobile station during a first timeslot, said data signal being transmitted at a power level that is variable due to downlink power control; transmitting a control channel signal from the base station throughout a cell in which the mobile station is operating, said control channel signal being transmitted at a power level that is constant; at the mobile station, measuring a received signal strength of the control channel signal; reporting the received signal strength of the control channel signal, as measured by the mobile station, to the base station; and compensating for the measured received signal strength of the control channel signal to derive signal strength information associated with the downlink data signal received by the mobile station during the first timeslot.
