Claim of US Patent No. 10,194,402

1. A method of operation of a base station in a cellular communications network, comprising:determining whether a wireless device is to operate in a long range extension mode or a normal mode where the long range extension mode is a mode of operation in which the wireless device is configured to maintain communication with the base station of the cellular communications network over an extended coverage range as compared to a coverage range over which the wireless device is configured to maintain communication with the base station of the cellular communications network in the normal mode of operation; and
applying different values for at least one parameter selected from a group consisting of: one or more radio link monitoring parameters, one or more radio link failure detection parameters, and one or more radio link failure recovery parameters depending on whether the wireless device is to operate in the long range extension mode or the normal mode,
wherein the base station determines that the wireless device is to operate in the long range extension mode in response to a request from the cellular communications network and sends a request causing the wireless device to apply, for each parameter of the at least one parameter, a modified value for the long range extension mode that is different than that which would be applied for the normal mode of operation.
