20150071095 | Establishing the Quality Indicator of a Radio Channel by Decorrelating Radio Conditions and Network Activity - A method establishing a quality indicator of a radio transmission channel in a first cell of a cellular network using a plurality of orthogonal frequency-division multiplexed subcarriers for transmitting data. A first transmitter located in the first cell transmits a reference control signal including a total-load control signal modulating one or more of the orthogonal subcarriers, during one or more first symbol times dedicated to transmission of symbols other than data symbols, and a useful-load control signal modulating one or more orthogonal subcarriers during at least one second symbol time dedicated to transmission of data symbols. A transmitter located in an adjacent cell transmits an interfering control signal modulating, during the first symbol time(s). The quality indicator is determined according to a measured quality indicator of the channel under the useful load and a measured quality indicator of the channel under the total load. | 03-12-2015 |
