Statistical model based control signal outer-loop adjustment

A device adapted to:

• transmit a control signal to a wireless device;
• transmit a data signal to a wireless device;
• detect an ambiguous state of reception of the control signal by the wireless device based on a feedback of reception of the data signal;
• and
• in response to detecting the ambiguous state of reception, update a link adaptation, LA, parameter used to choose a coding scheme and power level for transmission of information in the control signal.

A network node in a cellular communications network, comprising:

• a processor;
• and
• a memory coupled to the processor, the memory containing instructions executable by the processor whereby the network node is operative to:
• transmit a control signal to a wireless device;
• transmit a data signal to a wireless device;
• detect an ambiguous state of reception of the control signal by the wireless device based on a feedback of reception of the data signal;
• and
• in response to detecting the ambiguous state of reception, update a link adaptation, LA, parameter used to choose a coding scheme and power level for transmission of information in the control signal.
