STATISTICAL MODEL BASED CONTROL SIGNAL OUTER-LOOP ADJUSTMENT

摘要

Systems and methods for control signal outer-loop adjustment are disclosed. In some embodiments, a method of operation of a network node in a cellular communications network is provided. The method includes transmitting a control signal and a data signal to a wireless device. The method also includes 5 detecting an ambiguous state of reception of the control signal by the wireless device based on a feedback of reception of the data signal. The method also includes, in response to detecting the ambiguous state of reception, updating a link adaptation (LA) parameter used to choose a coding scheme and power level for transmission of information in the control signal. By updating the LA 10 parameter in response to detecting the ambiguous state of reception, the network node may provide improved performance.
