Patent ID: 8767574

Claim:
A method of estimating a received uplink signal power of a first transmission channel at a receiving node in a communications system, wherein the receiving node is a base station, wherein a received signal comprises information transmitted by a transmitting node over at least two transmission channels, wherein the transmitting node is a mobile station, the method comprising: measuring the received uplink signal power of a second of the at least two transmission channels; estimating a relationship between the transmission power of the second transmission channel and the transmission power of the first transmission channel; and estimating the received uplink signal power of the first transmission channel using the measurement of the received uplink signal power of the second transmission channel and said estimated relationship; measuring the received uplink signal power of at least one further transmission channel; estimating a relationship between the transmission power of the further transmission channel to the transmission power of the first transmission channel; and wherein estimating the received uplink signal power of the first transmission channel further comprises using the received uplink signal power of the at least one further transmission channel and the at least one estimated relationship between the transmission power of the first and further transmission channels.
