A method is disclosed of a wireless communication device comprising a radio transceiver and a first radio access control unit adapted to control operation of the wireless communication device in association with a first network node of a first cellular communication network. The method comprises (during use of the radio transceiver by the first radio access control unit) indicating a worse than actual channel condition to the first network node, monitoring a change in code rate of signals transmitted from the first network node in response to the worse than actual channel condition indication, determining a relation between the worse than actual channel condition indication and the code rate change, and determining an offset value based on the determined relation. The offset value is applicable to offset a channel condition indication value to be transmitted to the first network node in association with a gap in the use of the radio transceiver by the first radio access control unit. Corresponding computer program product, arrangement and wireless communication device are also disclosed, as well as using a server for storing the offset values.
