Abstract:
A method in a radio network node for dynamic carrier mode switching is provided. The radio network node is comprised in a radio communications system. The radio network node is configured to operate in a legacy mode and is further configured to operate in a non legacy mode. At least one carrier is operated so that it switches (602) from non legacy mode to legacy mode. When operating the carrier in the legacy mode, the radio network node signals (603) with a user equipment. The user equipment operates in legacy mode, but can not operate in non legacy mode. The radio network node then operates the at least one carrier so that it switches (604) from legacy mode back to non legacy mode.
