Abstract
A telecommunications network comprising a first unit and a second unit. The second unit measures the accuracy with which it receives data and transmits a value representing that accuracy to the first unit. The first unit adjusts its maximum transmission power to the second unit dependent upon said value.
Claims16
A telecommunications network comprising a first unit and a second unit, the second unit comprising means operative to determine a value representative of the accuracy with which data is received from the first unit and to transmit said value to the first unit, the first unit being operative to adjust the maximum power with which the first unit sends data to the second unit dependent upon said value.
A method of adjusting maximum downlink power in a call between a first unit and a second unit in a telecommunications network, comprising the steps of:
- the second unit determining a value representative of the accuracy with which data is received from the first unit;
- the second unit transmitting said value to the first unit;
- and
- the first unit adjusting the maximum power with which the first unit sends data to the second unit dependent upon said value.
A base station comprising means operative to receive from a subscriber unit a value representative of the accuracy with which data sent downlink from the base station was received, the base station further comprising means operative to adjust the maximum downlink power for further downlink data transmissions dependent upon said value.
A radio network controller (RNC) comprising comparator means operative to process a value representative of accuracy with which data was received by a subscriber unit by comparing said value to at least one threshold, and dependent upon the outcome of the or each comparison generating a control signal for adjusting maximum downlink transmission power of a transmitter/receiver station (Node B).
